Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer device, and an object of the present invention is to allow a plurality of transfer tables to stop at the end of the transfer without impact, and to prevent objects to be transferred from being displaced at the end of the transfer. The purpose of the present invention is to ensure that the plurality of tables are positioned securely at the above-mentioned end position and that they do not inadvertently move back.

An embodiment of the present invention will be described below with reference to drawings of an automatic assembly apparatus for resin molded products.

First, an overview of the transfer device of this embodiment will be explained with reference to FIG. 1. A table 2 for stocking metal substrates to which resin is bonded is movably arranged in the frame. A frame body, so-called magazine 3, for storing metal substrates is positioned and fixed.

The function of the table 2 is to move the next magazine to a predetermined position, that is, below the substrate holding part 4, which will be described later, when there are no more substrates stored in the center of a certain magazine 3. Therefore, the above-mentioned board holding part 4 will be explained as follows.
This is a detection device 6 (phototube,
(consisting of limit switches, etc.)
The metal substrate is raised to a predetermined height, and is automatically raised by the thickness of the substrate that decreases as the assembly process progresses.

Although the position of the metal substrate is predetermined by the magazine 3, the substrate guide 5 serves to ultimately determine the position of the metal substrate because the accuracy is rough.

Incidentally, when the stock table 2 moves, in order to prevent the magazine 3 above it from colliding with the lower end of the board holding part 4, the board holding part 4 is automatically raised to a position where it will not collide.

Next, the substrate gold suction unit 7 is provided close to the substrate guide 5, and this is a rotating plate 9 that moves horizontally and rotates at the end of the table 8 that protrudes in the direction of the guide 5.
It has a suction block 10 that moves back and forth based on this rotary plate 9 and suctions a metal substrate.

When a metal substrate is lifted up by the substrate holding part 4 and the detection device 61 of the substrate guide 5 is set at a certain height, the substrate suction part 7 is rotatably attached to the support plate la of the frame 1. It is automatically tilted to a predetermined angle and held by the attached rotating part 11. In this state, the suction block 10 moves forward,
The metal substrate inside the substrate guide 5 is pulled 1 by the suction force of the air.
While taking out only the sheet and holding it, it retreats to the original state, rotates, and returns. Incidentally, the rotating section 11 constitutes a part of the lateral movement guide 12 of the substrate suction section 7. The sheet metal suction unit 7 that has taken out and held the metal substrate is moved laterally to the right on the table guide 13 by the driving force of the lateral movement drive unit 14, and is stopped and fixed at a predetermined position at the right end. Note that the substrate gold adsorption unit 7 is made up of two blocks, and the pitch is different when the metal substrate is taken out from the substrate metal guide 5 and when it is moved to the right end (when it is attached to a mold). The pitch is automatically changed while moving laterally on the guide 13. After the board suction unit 7 has made a lateral movement, when a signal indicating that the board is mounted is OK is generated on the rail 21 located opposite to the board suction unit 7, the metal board held by the lock 10 is moved to the rail 21 by suction. It is automatically fed and installed. The seal 21 is attached to the front surface of the cavity block 16 so as to extend from side to side via a rail guide 22 fixed to the fixed mold cavity block 16 constituting the automatic molding machine.

Note that the metal substrate A attached to the rail 21
It is positioned in such a way that it does not move inadvertently. When the metal substrate A is mounted in this way, the preheating section 1
5 comes into contact with the substrate A, heats the substrate A to an appropriate temperature, and prepares to feed it into the mold. As described above, the steps from mounting the metal substrate A to the rail 21 to preheating are performed with the molds closed, that is, with the core flock 17 in contact with the cavity block 16. Before the mold opens, upon receiving a signal from the molding machine, the preheating section 15 retreats and separates from the metal substrate A on the rail 21. This mold opening process will be described later.
After retreating (mold opening completed), the claw 1 of the substrate feeding section 18
9 rotates to sandwich the metal substrate A mounted on the rail 21 between the adjacent claws 19, 19, and in that state move it laterally to the right to place the metal substrate A at a predetermined position in the mold. At the same time, the substrate B, which has already been resin-molded, is ejected from the mold and fed into the substrate take-out section 20. After this, the claw 19 rotates back to its original position, separates from the metal substrate A, and returns to its original state again. After it is detected that the claws 19 have returned, the mold is tightened, that is, the core block 17 comes into contact with the cavity block 16 to perform the molding process, and this operation is repeated thereafter. Next, each part will be explained in detail.

First, the details of the substrate holding part 4 are shown in FIG.

It has a motor 202 for driving the substrate lifting screw 201 up, a motor 203 for driving it down, and a cylinder 204 for removing and disengaging the clutch 206 when the screw 201 is lowered,
When the screw 201 is lowered, the cylinder 204 moves downward and lowers the first clutch 206 through the connecting fitting 205.
Disengage the second clutch 207.

In this state, the lowering motor 203 is rotated and the rotation is transmitted from the pulley 208 to the pulley 209 through the transmission band. The pulley 209 and the second clutch 207 are connected to the shaft 21
0, and a gear 211 is also attached in the same way. Rotation is transmitted from the gear 211 through the gear 212 to a nut holder 214 housed in a housing 213 attached to the main body. A nut 215 is fixed within the nut holder 214 with a key 216.
The force of the lowering motor 203 is transmitted through the above path, and the screw 201 is lowered. A rotation stopper 217 is attached to the lower end of the screw 201, and its tip is held by a guide 218 fixed to the main body, so that it can move up and down but cannot rotate. When ascending, the clutch detachment cylinder 204 is engaged, the clutches 206 and 207 are engaged, and the ascending motor 20
2 force is transmitted to raise the screw 201. Next, the substrate adsorption section 7 will be explained using FIGS. 3 to 5. Laterally moving table 301, 302 (indicated by number 8 in FIG. 1)
At the end of the movement (left end, right end), hold the table 3

When the table 302 moves to the other end, the fixed pawl 307 is returned by the pawl release cam 309, the hook of the reverse prevention pawl 305 is released, and the tables 301 and 302 are moved. The rotation of the motor 310 of the shaft 311 is transmitted from the table moving motor 310, and the claw release cam 309 is attached to the shaft 311.
The transmission body (sprocket) 312 and the first connecting plate 3 that move the
13 is fixed, and a connecting pin 314 is attached to the connecting plate 313. The transmission body 312 and the claw release cam 309 are connected by a connecting body (such as a chain) 315. At a position corresponding to the first connecting plate 313, a second connecting plate 316 is fixed to a shaft 317 and held in a rotatable state. etc.) 318 is fixed. The difference between the table 301 and the transmission body 318 is a connecting body (such as a chain) 315. When the table is moved to the left end, the connecting pin 314 is connected to the connecting plate 314.
When the table moves to the right from this state where it is touching the left side of the notch (see Figure 4), the motor 301
rotates the transmission body 312 clockwise through the reverse shaft 311, and rotates the claw release cam 30 through the coupling body 315.
9 to the right, the fixed side claw 307 is moved backward, and the hook with the reverse prevention claw 305 attached to the table 301 is released. Then, the connecting pin 314 hits the right side of the notch of the connecting plate 316, and the connecting plate 316 rotates together with the connecting plate 313 and the connecting pin 314, and the table 301 is moved to the right end via the shaft 317, the transmission body 318, and the connecting body 315, and then The table 302 also moves accordingly. The state in which the table is at the right end is shown in FIG. The operation progresses from FIG. 4.
