[0052] A notch 210 is provided on an inner side surface of the receiving groove 203, and a laser level 211 for detecting the straightness of the circuit board is installed inside the notch 210. An extension rod 212 is slidably inserted on a side surface of the carrier plate 201 away from the positioning plate 102. The conveying assembly 2 also includes a cylindrical groove 213 provided on a side surface of the carrier plate 201, and the extension rod 212 is slidably matched with the cylindrical groove 213. The inner peripheral side surface of the cylindrical groove 213 is symmetrically provided with a slide groove 214. The peripheral side surface of the extension rod 212 is symmetrically fixedly connected with a slide rod 215 that is slidably matched with the slide groove 214. A second spring 216 is fixedly connected between one end of the extension rod 212 and the inner bottom surface of the cylindrical groove 213. The top of the base 101 is symmetrically fixedly connected with a contact plate 103 that is slidably matched with the conveying assembly 2 (the contact plate 103 has straight portions at both ends and an inclined portion in the middle, as shown in FIG. Figure 2 ), the contact plate 103 and the convex ball plate 208 are slidably matched;

[0053] The top of the base 101 is symmetrically fixed with a blanking assembly 3 for automatic blanking of circuit boards. The blanking assembly 3 includes an L-shaped rod 301 symmetrically fixedly connected to the top of the base 101, a storage box 302 is fixedly connected between the two L-shaped rods 301, and the two sides of the storage box 302 and the L-shaped rod 301 are vertically arranged with a first blanking opening 303, an outer side surface of the storage box 302 is fixedly connected with a first electromagnet plate 304, and an outer side surface of the storage box 302 is fixedly matched with a material guide 4;

[0054] The material guide member 4 includes a material guide frame 401 fixedly connected to an outer side surface of the storage box 302, two opposite inner sides of the material guide frame 401 are slidably connected to U-shaped guide plates 402, a U-shaped connecting plate 403 is fixedly connected between the two U-shaped guide plates 402, and a second electromagnetic plate 404 away from the U-shaped guide plate 402 is fixedly connected to the top of the material guide frame 401;

[0055] The unloading component 3 also includes a pushing member 5 fixedly connected to the top of the base 101, and the pushing member 5 includes a first fixed plate 501 fixedly connected to the top of the base 101, and a cylinder 502 is fixedly connected to one side of the first fixed plate 501, and an output end of the cylinder 502 is fixedly connected to a push plate 503 that slides with the first unloading port 303. The support component 1 also includes a plurality of support rods 104 symmetrically fixedly connected to the bottom of the base 101, and a second unloading port 105 that is compatible with the supporting plate 201 is symmetrically opened on the top of the base 101, and a guide groove 106 that slides with the support column 202 is opened on the top of the base 101.

[0056] The operation process of this embodiment is as follows: the circuit board is neatly placed in the storage box 302 (the receiving groove 203 in the initial conveying component 2 is opposite to the second unloading port 105, at this time, the convex ball plate 208 is in contact with the contact plate 103 on the left, and the distance between the two supporting plates 206 in the conveying component 2 is greater than the width of the second unloading port 105), the conveying component 2 is controlled to move to the inclined portion position on the contact plate 103, and the conveying component 2 stops moving. At this time, the receiving groove 203 on the carrying plate 201 is opposite to the bottom of the guide frame 401. Synchronously, the convex ball plate 208 drives the two cross plates 204 to approach each other under the contact of the inclined portion of the contact plate 103, and then drives the supporting plate 206 and the limiting plate 205 to move in the direction of approaching each other (the distance between the two supporting plates 206 is less than the width of the circuit board, and the distance between the two limiting plates 205 is less than the width of the circuit board). The distance is greater than the width of the circuit board), and then the cylinder 502 is controlled, and the cylinder 502 drives the push plate 503 to move toward the inside of the storage box 302, and the push plate 503 pushes the circuit board located at the bottom to move toward the outside of the storage box 302, so that the circuit board moves to the inside of the U-shaped guide plate 402, until the circuit board moves to conflict with the second electromagnetic plate 404, and then the second electromagnetic plate 404 is energized, so that the second electromagnetic plate 404 drives the U-shaped guide plate 402 to move away from the circuit board, so that it is out of contact with the circuit board, and the circuit board will accurately fall into the receiving groove 203, and then the second electromagnetic plate 404 is closed, and the push plate 503 is reset at the same time, and then the first electromagnetic plate 304 is started, and the first electromagnetic plate 304 attracts the U-shaped connecting plate 403 to move to the right, thereby driving the U-shaped guide plate 402 to move to the right until it is reset (such as Figure 7 , 8 , 9).

[0057] After the circuit board is loaded into the receiving groove 203, the conveying component 2 is continuously controlled to move toward the direction close to the positioning plate 102, so that the convex ball plate 208 continues to contact the inclined portion on the contact plate 103, thereby driving the limit plate 205 and the support plate 206 to move toward the outer wall of the circuit board, so that the limit plate 205 and the support plate 206 are pressed against the outer wall of the circuit board to limit the circuit board (at this time, there is still a gap between the two support plates 206, in order to better perform the subsequent stamping deformation operation).

[0058] After the convex ball plate 208 abuts against the straight part of the abutment plate 103 near the positioning plate 102, the conveying assembly 2 continues to move toward the positioning plate 102 until it abuts against the positioning plate 102, and then collides with the circuit board. Finally, a laser level is used to detect whether the top surface of the circuit board is horizontal. If the circuit board is horizontal, there is no deformation, which means it is qualified. If the circuit board is not horizontal, it is bent, which means it is unqualified.

[0062] The operation process of this embodiment is: when the two extension plates 604 move away from each other at the bottom of the first mounting plate 603 (a limiting groove matching the two extension plates 604 is provided at the bottom of the first mounting plate 603), the two spur plates 807 are driven to move in the direction of moving away from each other (no teeth are provided in the middle of the spur plates 807), so that the spur plates 807 drive the meshing driving gear 803 to rotate, further drive the first rotating shaft 802 and the first bevel gear 804 to rotate, and then drive the second bevel gear 810 meshing therewith to rotate, so that the second bevel gear 810 drives the screw rod 809 to rotate, and the screw rod 809 drives the special-shaped plate 811 to move, so that the special-shaped plate 811 drives the conveying component 2 to move, and provides power for the movement of the conveying component 2.

[0063] The toothless part of the spur plate 807 moves to the position where it is aligned with the driving gear 803. At this time, the conveying assembly 2 is just directly below the storage box 302. After the circuit board is unloaded into the conveying assembly 2, the spur plate 807 continues to move until the conveying assembly 2 abuts against the positioning plate 102. After the deformation detection of the circuit board is completed, the conveying assembly 2 moves in the opposite direction until the driving gear 803 contacts the convex plate 904, so that the convex plate 904 drives the trigger plate 905 to move upward and abut against the switch 902. The trigger switch 902 energizes the second electric telescopic rod 1002, and the second electric telescopic rod 1002 drives the lifting plate 1003 to move upward, thereby driving the toothed plate 100 4 moves in the direction close to the driving gear 803, so that the latch plate 1004 is stuck on the driving gear 803, and the driving gear 803 is locked, thereby ensuring the stability of the parking position of the conveying component 2 (the first electric telescopic rod 602 in the pressing component 6 stops moving downward), until the conveying component 2 moves to the straight part where the resistance plate 103 is away from the positioning plate 102, at this time, the circuit board in the conveying component 2 is facing the second unloading port 105, and under the elastic force of the first spring 209, the supporting plate 206 and the limiting plate 205 are driven to move in the direction away from each other, so that the circuit board falls from the conveying component 2, and the unloading of the circuit board is completed.
