[0055] The rotating disc 21 is coaxially and rotatably connected with the open ring 20, and the rotating disc 21 is provided with a groove. The width of the groove is matched with the width of the opening of the open ring 20.

[0056] The two sides of the open ring 20 are fixedly connected with second connecting plates 27, one of the second connecting plates 27 is rotatably provided with a first gear 22, and the other second connecting plate 27 is rotatably provided with a second gear 23. The rotating disc 21 is coaxially and fixedly provided with an open gear ring 24, and the first gear 22 and the second gear 23 are engaged with the open gear ring 24. The distance between the first gear 22 and the second gear 23 is greater than the width of the groove of the rotating disc 21, and at least one of the first gear 22 and the second gear 23 is kept engaged with the open gear ring 24 by rotating the rotating disc 21.

One of the pulleys is coaxially and fixedly connected with the first gear 22, the other pulley is coaxially and fixedly connected with the second gear 23, and the transmission belt is arranged between the two pulleys. The first motor 19 drives the first gear 22 to rotate, and the second gear 23 rotates under the action of the belt transmission structure 28, and the open gear ring 24 rotates.

[0058] Two third sliding blocks 31 are slidingly connected to the upper limit of the rotating disc 21, and each third sliding block 31 is fixedly connected with a pair of shears 32. Specifically, the rotating disc 21 is fixedly installed with a second double-shaft motor 29, and the two motor shafts of the second double-shaft motor 29 are fixedly connected with a second threaded rod 30 in the same straight line. The two third sliding blocks 31 correspond to the two second threaded rods 30, and the third sliding block 31 is threadedly connected with the corresponding second threaded rod 30.

[0059] The second double-shaft motor 29 drives the second threaded rod 30 to rotate, thereby making the two third sliding blocks 31 approach or move away from each other, and making the two shears 32 approach or move away from each other.

[0060] The shears 32 are provided with an installation groove on the side close to the circuit board module 1, and the installation groove is provided with an elastic air cushion 36, and the sandpaper 33 is fixedly connected with the elastic air cushion 36.

[0061] The third sliding block 31 is fixedly connected with a connecting cavity 34, and the connecting cavity 34 is in communication with the air cavity 35 of the elastic air cushion 36. The rotating disc 21 is fixedly installed with a fixed block 25, and the two ends of the fixed block 25 are fixedly installed with a piston rod 26. The two piston rods 26 correspond to the two connecting cavities 34, and the piston rod 26 is arranged in cooperation with the corresponding connecting cavity 34. When the two third sliding blocks 31 approach each other, the connecting cavity 34 gradually approaches the corresponding piston rod 26, the piston rod 26 extends into the connecting cavity 34, and the piston rod 26 and the connecting cavity 34 are in sealing sliding cooperation, thereby making the air in the connecting cavity 34 be squeezed into the air cavity 35, making the elastic air cushion 36 expand outward, and the sandpaper 33 move outward. After the shears 32 cut off the connecting piece 2, the sandpaper 33 abuts against the broken section, and then the rotating disc 21 is rotated, and the sandpaper 33 grinds the broken section.

[0062] The clamping assembly for fixing the circuit board module 1 is arranged on the supporting plate 8. The clamping assembly comprises a clamping plate 11 and a clamping block 12. The supporting plate 8 is fixedly installed with a first double-shaft motor 14, and the two motor shafts of the first double-shaft motor 14 are in the same straight line. The two output ends of the first double-shaft motor 14 are fixedly connected with a first threaded rod 15, the clamping plate 11 is threadedly connected with one of the first threaded rods 15, and the other first threaded rod 15 is threadedly connected with a connecting block 13. The two ends of the connecting block 13 are fixedly connected with the clamping block 12.

[0063] In use, the main terminal material belt 3 after secondary injection molding is conveyed to the upper front of the base 4.

[0064] The electric push rod 5 is started to move the supporting plate 8 upward, and then the slide rail 9, the first slide block 10, the second slide block 16 and the cutting assembly are moved upward, the guide block 1601 slides along the guide groove 7, and the second slide block 16 moves along the guide groove 7 away from the circuit board module 1. With the upward movement of the cutting assembly, the connecting piece 2 gradually locates in the groove of the rotating disc 21.

[0065] Since the cutting pliers 32 have a certain thickness, if the cutting is directly performed from the connecting position of the connecting piece 2 and the circuit board module 1, stress extrusion is caused to the circuit board module 1, which may cause extrusion damage to the circuit board module 1, and then adversely affect the circuit board module 1. The closer the cutting point is to the circuit board module 1, the greater the stress transmitted to the circuit board module 1, and the more likely the extrusion damage to the circuit board module 1. Therefore, the cutting assembly is moved away from the circuit board module 1, the shearing point is away from the circuit board module 1, and then the influence of the shearing stress on the circuit board module 1 is reduced.

[0066] Then, the first double-shaft motor 14 is started, and the first threaded rod 15 rotates. The clamping plate 11 and the connecting block 13 are moved close to each other, and the clamping plate 11 and the clamping block 12 clamp and fix the circuit board module 1.

[0067] Then, the second double-shaft motor 29 is started, the second threaded rod 30 rotates, the two third slide blocks 31 move close to each other, the cutting pliers 32 move close to each other to shear the connecting piece 2, at this time, a part of the connecting piece 2 is reserved to be connected with the circuit board module 1, and the circuit board module 1 is separated from the carrier strip of the main terminal strip 3. The end surface of the connecting piece 2 is rectangular.

[0068] The second double-shaft motor 29 is reversely rotated, and the two cutting pliers 32 move away from each other.

[0069] Then, the first motor 19 is started, the first gear 22 rotates, the second gear 23 rotates, the open tooth ring 24 rotates, the rotating disc 21 rotates, and the rotating disc 21 drives the cutting pliers 32 to rotate, so that the rotating disc 21 rotates by 90 degrees, and at this time, the blade of the cutting pliers 32 is parallel to the long side of the connecting piece 2.

[0070] Then, the supporting plate 8 is moved downward by the electric push rod 5, the clamping assembly drives the circuit board module 1 to move downward, the cutting assembly moves downward, the guide block 1601 slides along the guide groove 7, and under the guidance of the guide groove 7, the cutting assembly moves toward the circuit board module 1, so that the cutting pliers 32 move close to the circuit board module 1. Until the cutting pliers 32 are located at the connecting position of the connecting piece 2 and the circuit board module 1.

[0071] The second double-shaft motor 29 is started to make the two shearing jaws 32 close to each other, and the shearing jaws 32 shear the connecting piece 2 along the long edge of the cross section. Since the reserved connecting piece 2 has been separated from the carrier tape of the main terminal tape 3, the reserved connecting piece 2 can fully absorb the stress generated during shearing, thereby reducing the extrusion damage to the circuit board module 1 and ensuring the quality of the circuit board module 1. Since the shearing jaws 32 shear along the long edge of the cross section, the contact area of the shearing jaws 32 and the connecting piece 2 is larger, and under the condition of equal shearing force, the larger the contact area of the shearing jaws 32 and the connecting piece 2, the smaller the pressure, and the smaller the stress generated. Therefore, shearing along the long edge of the cross section makes the stress on the unit area relatively small, and the stress distribution is relatively uniform, which helps to reduce local stress concentration, thereby reducing the adverse effects of stress on the circuit board module 1 and ensuring the quality of the circuit board module 1.

[0072] During the process of the two third sliders 31 approaching each other, the connecting cavities 34 gradually approach the corresponding piston rods 26, the piston rods 26 extend into the connecting cavities 34, the air in the connecting cavities 34 is extruded into the dynamic air cavities 35, the elastic air cushions 36 expand outward, the sandpaper 33 moves outward, and when the shearing jaws 32 cut the connecting piece 2, the sandpaper 33 abuts against the cross section. Then the first motor 19 is started to make the rotating disc 21 rotate, the cutting assembly rotates, the sandpaper 33 slides along the cross section, and then the cross section is polished.

[0073] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
