[0028] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0029] Such as Figures 1-6As shown in the figure, the utility model discloses a pin cutting and bending mechanism for electronic devices, which includes a machine base 20, a driving device 21 arranged on the machine base 20, and a number of corresponding first movable blocks 22 and second movable blocks 23. A concave portion 221 is provided on the first movable block 22. A cutting knife portion 222 is provided at the lower end of the concave portion 221, and a bending portion 223 is provided at the upper end of the concave portion 221. A convex portion 231 corresponding to the concave portion 221 is provided on the second movable block 23. The upper surface of the cutting knife portion 222 is flush with the lower surface of the convex portion 231, and a distance b is maintained between the lower surface of the bending portion 223 and the upper surface of the convex portion 231. Specifically, the distance b > the diameter of the pin 31 on the electronic device 30. The driving device 21 can drive the first movable block 22 and the second movable block 23 to move closer to or away from each other, so that the cooperation between the cutting knife portion 222 and the convex portion 231 cuts the pin 31 on the electronic device 30, and the cooperation between the bending portion 223 and the convex portion 231 bends the pin 31 on the electronic device 30. When the convex portion 231 extends into the concave portion 221, the pin 31 is first cut by the cooperation between the cutting knife portion 222 and the convex portion 231, and then the pin 31 is bent by the cooperation between the bending portion 223 and the convex portion 231, so as to complete the cutting and bending of multiple pins 31 at one time.

[0030] The pin cutting and bending mechanism for the electronic device 30 further includes a first sliding seat 24 and a second sliding seat 25 arranged oppositely. Both the first sliding seat 24 and the second sliding seat 25 are slidably connected to the machine base 20. A number of the first movable blocks 22 are arranged at intervals along the X-axis on the first sliding seat 24, and a number of the second movable blocks 23 are arranged at intervals along the X-axis on the second sliding seat 25. The driving device 21 can drive the first sliding seat 24 and the second sliding seat 25 to move in opposite directions along the X-axis, so that the first movable block 22 and the second movable block 23 move closer to or away from each other; by setting the first sliding seat 24 and the second sliding seat 25, arranging the first movable block 22 on the first sliding seat 24, and arranging the second movable block 23 on the second sliding seat 25, driving the first sliding seat 24 and the second sliding seat 25 to move in opposite directions by the driving device 21 can realize the movement of the first movable block 22 and the second movable block 23 closer to or away from each other. The sliding connection method makes the movement of the first movable block 22 and the second movable block 23 stable, improving the cutting and bending effects of the pin 31.

[0031] At least one first mounting seat 241 is provided on the first sliding seat 24. A second mounting seat 251 corresponding to the first mounting seat 241 one by one is provided on the second sliding seat 25. Specifically, the first mounting seat 241 is connected to the first sliding seat 24 by screws, and the second mounting seat 251 is connected to the second sliding seat 25 by screws. The number of both the first mounting seat 241 and the second mounting seat 251 is two. The two first mounting seats 241 are distributed along the X-axis direction. An avoidance space 26 for the insertion of the pin 31 is formed between the first mounting seat 241 and the second mounting seat 251. The first movable block 22 is detachably mounted on the first mounting seat 241. Specifically, the first movable block 22 is detachably mounted on the first mounting seat 241 by an interference fit method or can also be detachably mounted on the first mounting seat 241 by screws. The second movable block 23 is detachably mounted on the second mounting seat 251. The mounting method of the second movable block 23 is the same as that of the first movable block 22. Both the concave portion 221 and the convex portion 231 are located in the avoidance space 26. By providing the first mounting seat 241 and the second mounting seat 251, during assembly, first assemble the first movable block 22 to the first mounting seat 241 and the second movable block 23 to the second mounting seat 251, and then assemble the first mounting seat 241 to the first sliding seat 24 and the second mounting seat 251 to the second sliding seat 25. The assembly and disassembly are convenient.

[0032] A blanking channel 27 is provided below the avoidance space 26. The blanking channel 27 is mounted on the machine base 20. A waste recycling box (not shown) is provided below the blanking channel 27. By providing the blanking channel 27 and the waste recycling box, the waste after the pin 31 is cut falls into the waste recycling box through the blanking channel 27, avoiding the waste from scattering everywhere.

[0033] The driving device 21 includes a first driving component 211 and a second driving component 212. The first driving component 211 can drive the first sliding seat 24 to move, and the second driving component 212 can drive the second sliding seat 25 to move. The driving force of the first driving component 211 > the driving force of the second driving component 212. During operation, the first driving component 211 first drives the first sliding seat 24 to move. After the first sliding seat 24 drives the first movable part to move in place, it stops. Next, the second driving component 212 drives the second sliding seat 25 to move. The second sliding seat 25 drives the second movable part to move. The convex portion 231 on the second movable part is inserted into the concave portion 221 on the first movable part. Since the driving force of the first driving component 211 > the driving force of the second driving component 212, the second movable part cannot push the first movable part to move, so that the positions of the concave portion 221 and the bending portion 223 remain unchanged, thus avoiding abnormal deformation and bending of the pin 31.

[0034] The first driving component 211 includes a first cylinder 2111 and a first lever 2112, and the second driving component 212 includes a second cylinder 2121 and a second lever 2122. The first lever 2112 and the second lever 2122 are both rotatably connected to the base 20. The first cylinder 2111 is transmission-connected to the first slide 24 via the first lever 2112, and the second cylinder 2121 is transmission-connected to the second slide 25 via the second lever 2122. By adopting a cylinder + lever driving structure, the lever can increase the driving force of the cylinder, so that the first movable block 22 and the second movable block 23 can easily cut and bend the pin 31, and the cutting and bending effects are good.

[0035] The lower end of the first lever 2112 is rotatably connected to the movable joint of the first cylinder 2111, the upper end of the first lever 2112 is rotatably connected to the first slide 24, the lower end of the second lever 2122 is rotatably connected to the movable joint of the second cylinder 2121, the upper end of the second lever 2122 is rotatably connected to the second slide 25, the driving force of the first cylinder 2111 is greater than the driving force of the second cylinder 2121, and the power arm of the first lever 2112 is equal to the power arm of the second lever 2122. It can be understood that the first cylinder 2111 and the second cylinder 2121 with equal driving forces can also be used, in which case the power arm of the first lever 2112 is greater than the power arm of the second lever 2122.

[0036] The machine base 20 is provided with a first limit seat 28 and a second limit seat 29, and the first limit seat 28 and the second limit seat 29 are arranged at a distance along the X-axis direction. The first slide 24 and the second slide 25 are both arranged between the first limit seat 28 and the second limit seat 29. The upper end of the first lever 2112 is rotatably connected to the first limit seat 28, and the upper end of the second lever 2122 is rotatably connected to the second limit seat 29.

[0037] A first adjusting screw 242 and a second adjusting screw 243 are respectively provided at the two ends of the first slide 24, and the axes of the first adjusting screw 242 and the second adjusting screw 243 are the same as the movement direction of the first slide 24. The first adjusting screw 242 cooperates with the first limit seat 28, and the second adjusting screw 243 cooperates with the second limit seat 29 to adjust the movement stroke of the first slide 24. During adjustment, the first adjusting screw 242 is rotated to make the first adjusting screw 242 screwed into the first slide 24 deeper. The first slide 24 moves a larger stroke toward the first limit seat 28 to make the first adjusting screw 242 abut against the first limit seat 28 and stop the first slide 24 from moving, indirectly adjusting the position of the first movable block 22 when it stops, thereby adjusting the degree of fit between the first movable block 22 and the pin 31, and improving the cutting and bending effects. The adjustment method of the second adjusting screw 243 is the same as the adjustment method of the first adjusting screw 242.

[0038] Both ends of the second sliding seat 25 are respectively provided with a third adjusting screw 252 and a fourth adjusting screw 253. The structure and principle of the third adjusting screw 252 are the same as those of the first adjusting screw 242, and the structure and principle of the fourth adjusting screw 253 are the same as those of the second adjusting screw 243, so they will not be described in detail.

[0039] It should be noted that the driving device 21 in the present invention can also adopt the mode of a single power unit + transmission mechanism to realize the reverse movement of the first sliding seat 24 and the second sliding seat 25; the electronic device 30 in the present invention can be a quartz crystal resonator, or can be an electronic device 30 such as a capacitor or resistor with pins 31.

[0040] The working principle of the present utility model:

[0041] The external manipulator transports the electronic device 30 above the first movable block 22 and the second movable block 23, and then moves the electronic device 30 downward so that the pins 31 on the electronic device 30 are inserted between the first movable block 22 and the second movable block 23. First, the first cylinder 2111 drives the first lever 2112 to rotate, and the first lever 2112 drives the first sliding seat 24 to move along the X-axis direction. The first sliding seat 24 drives the first movable block 22 to move. When the side of the cutting part 222 facing the convex part 231 abuts against the side wall of the pin 31, the first sliding seat 24 remains stationary. Then, the second cylinder 2121 drives the second lever 2122 to move, and the second lever 2122 drives the second sliding seat 25 to move. The second sliding seat 25 drives the second movable block 23 to move. During the process of the convex part 231 being embedded into the concave part 221, the pin 31 is first cut off through the cooperation of the cutting part 222 and the convex part 231, and then the pin 31 is bent through the cooperation of the bending part 223 and the convex part 231. The waste material after the pin 31 is cut off falls into the waste recycling box through the blanking channel 27, and the external manipulator removes the electronic device 30 whose pins 31 have been cut off and bent.

[0042] In summary, in the present utility model, a driving device 21, a number of first movable blocks 22 and second movable blocks 23 which are in one-to-one correspondence are arranged on the machine base 20.

The upper surface of the cutting blade portion 222 is flush with the lower surface of the convex portion 231, and a distance b is maintained between the lower surface of the bending portion 223 and the upper surface of the convex portion 231. During operation, the pins 31 of the electronic device 30 are inserted between the first movable block 22 and the second movable block 23. The driving device 21 drives the first movable block 22 and the second movable block 23 to move closer. When the convex portion 231 extends into the concave portion 221, the pins 31 are first cut by the cooperation of the cutting blade portion 222 and the convex portion 231, and then the pins 31 are bent by the cooperation of the bending portion 223 and the convex portion 231, so as to complete the cutting and bending of multiple pins 31 at one time, with high production efficiency and reduced production costs.

[0043] The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model.
