The loading conveyor belt 10, the upper cutting assembly 26, the lower cutting assembly 17, the upper loading seat assembly 12, the lower loading seat assembly 16, the upper discharge conveyor belt 25, and the lower discharge conveyor belt 19 are all installed on the production line and connected to the control system.

[0020] A first picking and unloading robot 11 is provided on one side of the loading conveyor belt 10 located at the discharge port; a second picking and unloading robot is provided on one side of the upper discharging conveyor belt 25 and the lower discharging conveyor belt 19 located at the feed port; the loading conveyor belt 10 takes away the diodes one by one through the first picking and unloading robot 11 and places them correspondingly in the diode embedding groove 21; the second picking and unloading robot 11 through the upper discharging conveyor belt 25 and the lower discharging conveyor belt 19 takes out the diodes in the diode embedding groove 21 and places them correspondingly on the upper discharging conveyor belt 25 and the lower discharging conveyor belt 19 for discharging.

[0021] The upper loading base assembly 12 and the lower loading base assembly 16 both include a lifting drive motor 27, a drive shaft 24, a rotation drive motor 36, a circular placement seat 22, an upper cutting support plate 23, a lower cutting support plate 20, and a threaded mounting sleeve 31; the drive shafts 24 of the upper loading base assembly 12 and the lower loading base assembly 16 are coaxially arranged.

[0022] One end of the drive shaft 24 is connected to the power output end of the lifting drive motor 27, and the other end of the drive shaft 24 is connected to the rotation drive motor 36; the power output end of the rotation drive motor 36 extends into the threaded mounting sleeve 31 and is coaxially threaded with the threaded mounting sleeve 31.

[0023] The circular placement seat 22 is fixedly sleeved in the middle of the outer side surface of the threaded mounting sleeve 31; an air storage cavity is formed inside the circular placement seat 22, and the air storage cavity is connected to the negative pressure air source through an air pipe; a plurality of diode embedding grooves 21 are arranged in a circumferential array on the opposite sides of the outer side surface of the circular placement seat 22, and each diode embedding groove 21 is provided with a negative pressure air hole 32 connected to the air storage cavity; negative pressure gas is provided to the air storage cavity by the negative pressure air source, so that the diode can be fixed in the diode embedding groove 21 to complete the cutting process.

[0024] The outer wall of the threaded mounting sleeve 31 and the area above or below the circular placement seat 22 are both provided with external threads. The upper cutting support plate 23 is coaxially sleeved on the outer side of the threaded mounting sleeve 31, threadedly connected to the threaded mounting sleeve 31, and located above the circular placement seat 22; the lower cutting support plate 20 is coaxially sleeved on the outer side of the threaded mounting sleeve 31, threadedly connected to the threaded mounting sleeve 31, and located below the circular placement seat 22; the distance between the upper surface of the upper cutting support plate 23 and the upper surface of the circular placement seat 22 is the required length of one pin of the diode; the distance between the lower surface of the lower cutting support plate 20 and the lower surface of the circular placement seat 22 is the required length of the other pin of the diode. The outer sides of the upper cutting support plate 23 and the lower cutting support plate 20 are both circumferentially arrayed with pin limiting grooves 14 that match the number of diode fitting grooves 21. When the length of the cutting pin needs to be adjusted, it is only necessary to rotate the upper cutting support plate 23 and / or the lower cutting support plate 20 to change the relative distance between them and the circular placement seat 22.

[0025] The upper cutting assembly 26 includes cutting structures A13 respectively arranged on opposite sides of the upper cutting space, and the lower cutting assembly 17 includes cutting structures B18 respectively arranged on opposite sides of the lower cutting space. Each cutting structure A13 and cutting structure B18 includes a cutting drive motor 30, a cutting drive shaft 40, an upper cutting blade 28, a lower cutting blade 29, and a connecting seat 35. One side of the cutting drive shaft 40 is connected to the power output end of the cutting drive motor 30, and the other side of the cutting drive shaft 40 is connected to the connecting seat 35. The upper cutting blade 28 should be arranged on the upper part of the connecting seat 35 away from the cutting drive motor 30, and the lower cutting blade 29 should be arranged on the lower part of the connecting seat 35 away from the cutting drive motor 30. Each upper cutting blade 28 and lower cutting blade 29 are configured as arc-shaped blades. During actual operation, the cutting drive motor 30 drives the upper cutting blade 28, the lower cutting blade 29 and the connecting seat 35 to move in the upward cutting space direction through the cutting drive shaft 40 to complete the cutting action.

[0026] Each upper cutting blade 28 and lower cutting blade 29 has a connecting plate 34 formed on the side facing the connecting base 35. The connecting base 35 is provided with a strip-shaped adjustment hole 39 for the connecting plate 34 to be inserted into. Waist-shaped holes 38 are provided on opposite sides of the adjustment hole 39 in the longitudinal direction. A mounting plate 37 is connected to one side of each connecting plate 34 that passes through the adjustment hole 39 and is secured to the waist-shaped hole 38 via bolts 41. This structural arrangement facilitates adjustment of the relative distance between the upper cutting blade 28 and the lower cutting blade 29.

[0027] The upper discharging conveyor belt 25 is connected to the lower discharging conveyor belt 19 through the inclined guide belt 15. Through such a structural setting, the diodes of the upper discharging conveyor belt 25 and the lower discharging conveyor belt 19 are finally merged into one discharging point, and only one discharging and receiving station is set up, saving personnel costs.

[0028] A guide rod 33 is provided between the connecting plate 34 of the upper cutting blade 28 and the lower cutting blade 29. By providing the guide rod 33, it is ensured that when adjusting the relative distance between the upper cutting blade 28 and the lower cutting blade 29, it can be adjusted along the guide rod 33 without deviation, thereby improving the accuracy and convenience of adjustment.

[0029] The present invention uses a loading conveyor belt to load the upper loading seat assembly and the lower loading seat assembly in turn, and loads the materials in a one-way manner, which simplifies the structure and reduces the space occupied by the equipment; the upper cutting assembly and the lower cutting assembly are used to synchronously cut the pins on both sides of the diodes on the upper loading seat assembly and the lower loading seat assembly, thereby improving processing efficiency.

[0030] The operating principle of this embodiment is:

[0031] 1. The upper loading seat assembly 12 moves to the position of the loading space, the rotary drive motor 36 drives the threaded mounting sleeve 31 to rotate, and the loading conveyor belt 10 places the diode into the diode fitting groove 21 of the circular placement seat 22;

[0032] 2. The upper loading seat assembly 12 is reset after completing the loading. At the same time, the lower loading seat assembly 16 moves to the position of the loading space to load the material. Then, the upper cutting assembly 26 starts the cutting action.

[0033] 3. While the lower loading base assembly 16 is loading the material, the upper cutting assembly 26 is reset after completing the cutting action, and the upper discharging conveyor belt 25 is discharging the material;

[0034] 4. After the upper discharging conveyor belt 25 completes discharging, the lower loading base assembly 16 completes loading and resets;

[0035] 5. The upper loading seat assembly 12 repeats the loading action. At the same time, the lower loading seat assembly 16 completes the cutting action and resets, and the lower discharging conveyor belt 19 discharges the material.

[0036] 6. Repeat the above steps.

[0037] The above-described embodiment merely represents one embodiment of the present invention. While the description is relatively specific and detailed, it should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
