[0003] The Chinese utility model publication number CN216291647U proposes a patch device for PCB circuit boards: the user rotates a pillar, which drives the placement box to rotate, and the placement box drives the circuit board inside it to rotate. When it rotates to correspond to the feed end of the patch device, the rod is inserted into the socket; by setting a limiting mechanism, the ring body squeezes the rod while rotating. One end of the rod is spherical, and the inside of the socket is also spherical. The rod pushes the slider to squeeze the spring, and the rod leaves the socket. As the ring body rotates ninety degrees, the rod is engaged with the socket again to limit the ring body.

However, the existing technology does not have a limiting mechanism to assist in limiting the position of the placement box. It may be difficult for the placement box to accurately align with the feed port of the placement machine, which may cause the circuit board to be inaccurately positioned during the processing, affecting the processing accuracy and reducing product quality.

[0006] 2. The ring body needs to squeeze the rod when rotating. The squeezing effect will cause wear on the surface of the rod and the ring body, accelerate the wear and aging of parts, and reduce the service life of the equipment. Utility Model Content

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-3 As shown, a PCB circuit board patch device includes: a base 1, a patch machine 2 is fixedly installed on the upper end of the base 1, a moving mechanism is slidably provided at the upper end of the base 1 and at a position on one side of the patch machine 2, and a rotating mechanism is provided above the moving mechanism.

[0022] Multiple circuit boards are placed on the rotating mechanism. The rotating mechanism is used to fix the circuit boards and rotate the circuit boards to be processed to the feed port position of the placement machine 2. The moving mechanism is used to push the circuit boards to be processed into the placement machine 2 for processing and then pull them out after processing is completed.

[0023] A receiving groove 3 is provided inside the base 1, and a motor 6 is fixedly installed inside the receiving groove 3. A screw rod 4 is rotatably provided inside the receiving groove 3. The output shaft of the motor 6 is fixedly connected to the end of the screw rod 4. The outer side of the screw rod 4 is threadedly connected to two sliders 5. A notch 7 is provided on the upper end surface of the base 1. The notch 7 is connected to the receiving groove 3, and the size of the notch 7 is adapted to the moving trajectory of the two sliders 5.

[0024] The moving mechanism includes two sliders 5 and a support plate 8 . The two sliders 5 pass through the notch 7 and are fixedly connected to the support plate 8 .

[0025] The motor 6 is started, and the output shaft of the motor 6 drives the screw rod 4 to rotate, so that the two sliders 5 drive the support plate 8 to move left and right in the horizontal direction.

[0026] The rotating mechanism includes a pillar 12, a fixed block 9, and a plurality of placement boxes 10. The bottom end of the pillar 12 is rotatably connected to the support plate 8, and the top end of the pillar 12 is fixedly connected to the fixed block 9. The fixed block 9 is circumferentially fixedly connected with a plurality of fixed rods 11. The ends of the fixed rods 11 are fixedly connected to the corresponding placement boxes 10. Both sides of the placement box 10 are threadedly connected with a second screw 20. The end of the second screw 20 passes through the side wall of the placement box 10 and is rotatably connected to a splint 19.

[0027] Place the circuit board in the placement box 10, rotate the two second screws 20, and the second screws 20 drive the clamping plates 19 to move toward the circuit board to clamp the circuit board.

[0028] A limiting mechanism is set on the side sliding of the placement machine 2 close to the placement box 10. The limiting mechanism and the rotating mechanism cooperate with each other to rotate the circuit board to be processed and limit it to the feed port position of the placement machine 2. The limiting mechanism includes a slide 16 and an embedded rod 21. The slide 16 is "L"-shaped, and the embedded rod 21 is arc-shaped. A slide groove 17 is provided on the side of the placement box 10 of the placement machine 2. One end of the slide 16 is slidably connected in the slide groove 17, and the other end of the slide 16 is fixedly connected to a stopper 18. The stopper 18 has a limiting groove near the side of the placement box 10. The placement box 10 is fixedly installed with an embedded rod 21 on the side close to the slide 16. The embedded rod 21 is adapted to the limiting groove, and the embedded rod 21 can enter the limiting groove.

[0029] The chute 17 needs to be specially designed so that when the slide plate 16 slides to the upper end of the chute 17 , the stopper 18 corresponds to the position of the feed port of the placement machine 2 .

[0030] The upper end surface of the support plate 8 is fixedly connected to a fixing plate 13, and a first screw 14 is threadedly connected to the fixing plate 13. A plurality of threaded holes 15 are opened around the pillar 12. The number of threaded holes 15 is the same as the number of the placement boxes 10, and the placement boxes 10 and the threaded holes 15 are arranged correspondingly.

[0031] When the pillar 12 is rotated, when one of the placement boxes 10 corresponds to the feed port position of the placement machine 2, the first screw 14 is rotated, and the first screw 14 is threadedly connected to the threaded hole 15 corresponding to the placement box 10, so that the pillar 12 is fixed and cannot rotate.

[0032] Working principle:

[0033] When a circuit board needs to be mounted, the circuit board is placed in the placement box 10 so that each placement box 10 contains a circuit board. The two second screws 20 on the placement box 10 are rotated, and the second screws 20 drive the clamping plate 19 to move toward the circuit board to clamp the circuit board.

[0034] Slide the slide 16 to the upper end of the slide groove 17. At this time, the slide 16 and the stopper 18 are between two adjacent placement boxes 10. Rotate the support 12 counterclockwise. The support 12 drives all the placement boxes 10 to rotate. The placement boxes 10 drive the circuit boards inside to rotate. When the embedded rod 21 of one of the placement boxes 10 enters the limit groove of the stopper 18, it indicates that this placement box 10 is aligned with the feed port of the placement machine 2. Rotate the first screw 14. The first screw 14 will be threadedly connected with the corresponding threaded hole 15, so that the support 12 is fixed.

[0035] After the circuit board to be processed rotates to the feed port position of the placement machine 2, the slide plate 16 is slid to the other end of the slide groove 17 so that the stopper 18 does not hinder the movement of the placement box 10, and the motor 6 is started. The output shaft of the motor 6 drives the screw 4 to rotate, so that the two sliders 5 drive the support plate 8 to move to the left. The support plate 8 drives one of the placement boxes 10 through the feed port of the placement machine 2 into the placement machine 2 for processing;

[0036] After the processing is completed, the motor 6 is controlled to rotate in the opposite direction and pull it out, and the first screw 14 is rotated in the opposite direction to turn the first screw 14 out of the threaded hole 15 so that the support 12 can rotate; then the subsequent placement box 10 is pushed into the placement machine 2 according to the above steps, and the processed circuit board is removed, and the unprocessed circuit board is installed again.

[0037] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
