Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 and Figure 2 shown, a jaw mechanism for PCB riveting includes a mounting plate 1, and a downward pressing assembly 2 is connected to one side of the mounting plate 1;

[0026] As Figure 4 shown, the downward pressing assembly 2 includes an L-shaped block 201, a cylinder 202 is fixedly connected to the back surface of the L-shaped block 201, an output end of the cylinder 202 is fixedly connected to a lifting block 203, the lifting block 203 is slidably connected to the L-shaped block 201, a pressing plate 204 is fixedly connected to the bottom of the lifting block 203, and a pressing groove 205 is provided on the pressing plate 204. When it is necessary to perform a riveting operation, the cylinder 202 is started, the piston rod of the cylinder 202 extends downward, pushing the lifting block 203 to slide on the L-shaped block 201, driving the pressing plate 204 to move vertically downward through the lifting block 203, pushing the rivet 13 to move downward. When the bottom of the rivet 13 contacts the target position, the continuously applied pressure pushes the rivet 13 to rivet the rivet on the PCB board. The automated downward pressing operation greatly speeds up the riveting speed, improves the production efficiency, reduces the space occupied by the equipment, and improves the compactness and flexibility of the production line.

[0027] As Figure 4 shown, a second slider 206 is fixedly connected to the lifting block 203, a second slide rail 207 is fixedly connected to the inside of the L-shaped block 201, and the second slider 206 is slidably connected to the second slide rail 207, which can ensure that the lifting block 203 always maintains a stable vertical movement during the lifting process, avoiding shaking and offset of the lifting block 203 during the movement, and improving the accuracy of riveting.

[0028] As Figure 1As shown, a fixing member 3 is fixedly connected to one side of the mounting plate 1, and an L-shaped block 201 is fixedly connected to the fixing member 3. Through the fixing member 3, the L-shaped block 201 can be firmly mounted on the mounting plate 1 to form a stable support structure.

[0029] As Figure 1 , Figure 2 and Figure 3 shown, a pneumatic finger 4 is fixedly connected to the bottom of the mounting plate 1. Output ends on both sides of the pneumatic finger 4 are fixedly connected with connecting blocks 5, and a first jaw 6 and a second jaw 7 are respectively fixedly connected to the two connecting blocks 5. The first jaw 6 and the second jaw 7 are arranged oppositely, and limiting grooves are provided on opposite surfaces of the first jaw 6 and the second jaw 7. When the pneumatic finger 4 operates, it drives the connecting blocks 5 through its output ends on both sides, and then drives the first jaw 6 and the second jaw 7 to move relatively, enabling flexible clamping or releasing of the rivet 13 and facilitating driving the rivet 13 to move in position.

[0030] As Figure 1 and Figure 3 shown, first sliders 8 are fixedly connected to the tops of both the first jaw 6 and the second jaw 7. First slide rails are fixedly connected to both sides of the bottom of the mounting plate 1, and the first sliders 8 are slidably connected to the first slide rails. The first jaw 6 and the second jaw 7 can maintain a stable posture and position during movement, avoiding clamping failure caused by shaking or deviation.

[0031] As Figure 1 shown, a support plate 9 is fixedly connected to the middle of the bottom of the mounting plate 1, a positioning rod 10 is fixedly connected to the bottom of the support plate 9, and a rivet 13 is sleeved on the outer surface of the positioning rod 10. The shape of the pressing groove 205 is U-shaped, the pressing groove 205 is sleeved on the outer surface of the positioning rod 10, and the pressing plate 204 is located above the rivet 13. When the jaw mechanism moves to directly above the rivet 13, the jaw mechanism moves downward, the positioning rod 10 is inserted into the top inside the rivet 13, and the rivet 13 can be clamped by the first jaw 6 and the second jaw 7.

[0032] As Figure 1 and Figure 2 shown, a limiting seat 11 is fixedly connected to the side of the mounting plate 1 away from the fixing member 3, and a rubber pad 12 is fixedly connected to the inside of the limiting seat 11. The rubber pad 12 is elastic. When the first jaw 6 and the second jaw 7 move away from each other and open, the rubber pad 12 can limit the maximum distance between the first jaw 6 and the second jaw 7 when they open.

[0033] Working principle: When the jaw mechanism moves to directly above the rivet 13, the jaw mechanism moves downward, the positioning rod 10 is inserted into the top inside the rivet 13, the pneumatic finger 4 operates, drives the connecting blocks 5 through its output ends on both sides, and then drives the first jaw 6 and the second jaw 7 to move relatively to clamp the rivet 13;

[0034] When moving the rivet 13 above the target position and when a riveting operation needs to be performed, the air cylinder 202 is activated. The piston rod of the air cylinder 202 extends downward, pushing the lifting block 203 to slide on the L-shaped block 201. The pressing plate 204 is driven by the lifting block 203 to move vertically downward, pushing the rivet 13 to move downward. When the bottom of the rivet 13 touches the target position, the continuously applied pressure pushes the rivet 13 to rivet it onto the PCB board.
