Photovoltaic junction boxes are crucial components of solar modules, primarily connecting the electricity generated by the solar cells to external wiring and conducting the current produced by the photovoltaic modules. The performance of the junction box assembly plays a key role, and to improve its performance stability, the dimensions of the internal columnar diodes need to be strictly controlled. Currently, the lack of automated lead cutting equipment in the manufacturing process of columnar diodes leads to low processing efficiency and inaccurate dimensional control. Utility Model Content

The diode storage device can vertically hold multiple columnar diodes. The diode discharging device can block the bottommost columnar diode in the diode storage device. The diode lateral turnover mechanism can drive a diode turnover block to move back and forth. When the diode turnover block moves below the diode storage device, the diode discharging device releases its obstruction of the bottommost columnar diode in the diode storage device, and the bottommost columnar diode falls onto the diode turnover block. The diode discharging device then returns to its original position and blocks the bottommost columnar diode in the diode storage device. The diode turnover block moves to the diode lead stamping mechanism, which, in conjunction with the diode turnover block, cuts the leads of the columnar diodes. After cutting, the diode turnover block moves to the diode unloading mechanism, which removes the columnar diodes from the diode turnover block for unloading.

[0015] The beneficial effects of this utility model are reflected in the following: In this technical solution, through the cooperation of various components, multiple columnar diodes are placed in the diode storage device during use. The diode discharging device blocks the bottom columnar diode in the diode storage device. The diode lateral turnover mechanism drives the diode turnover block to move below the diode storage device. The diode discharging device releases the block on the bottom columnar diode in the diode storage device, and the bottom columnar diode falls onto the diode turnover block. The diode discharging device returns to its original position and blocks the bottom columnar diode in the diode storage device. Then, the diode turnover block moves to the diode pin stamping mechanism. The diode pin stamping mechanism works with the diode turnover block to cut the pins of the columnar diode. After cutting, the diode turnover block moves to the diode unloading mechanism. The diode unloading mechanism takes out the columnar diode from the diode turnover block for unloading. In this way, this device can automatically cut the pins of columnar diodes, realize precise control of the pin size of columnar diodes, and improve the production efficiency of columnar diodes.

[0036] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0037] Example 1

[0038] like Figures 1-11 As shown, this embodiment provides a columnar diode lead cutting device, including a base plate 6. The base plate 6 is equipped with a diode storage device 1, a diode discharging device 2, a diode lateral turnover mechanism 3, a diode lead stamping mechanism 4, and a diode unloading mechanism 5. The diode storage device 1 can vertically place multiple columnar diodes. The diode discharging device 2 can block the lowest columnar diode in the diode storage device 1. The diode lateral turnover mechanism 3 can drive a diode turnover block 35 to move back and forth. When the diode turnover block 35 moves to below the diode storage device 1, the diode... The tube discharge device 2 releases the obstruction of the bottom columnar diode in the diode storage device 1, and the bottom columnar diode in the diode storage device 1 falls onto the diode turnover block 35. The diode discharge device 2 returns to its original position to block the bottom columnar diode in the diode storage device 1. The diode turnover block 35 moves to the diode pin stamping mechanism 4. The diode pin stamping mechanism 4 cooperates with the diode turnover block 35 to cut the pins of the columnar diode. After cutting, the diode turnover block 35 moves to the diode unloading mechanism 5. The diode unloading mechanism 5 takes out the columnar diode from the diode turnover block 35 for unloading.

[0039] In this embodiment, through the cooperation of various components, multiple columnar diodes are placed in the diode storage device 1 during use. The diode discharging device 2 blocks the bottommost columnar diode in the diode storage device 1. The diode lateral turnover mechanism 3 drives the diode turnover block 35 to move below the diode storage device 1. The diode discharging device 2 releases the block on the bottommost columnar diode in the diode storage device 1, and the bottommost columnar diode in the diode storage device 1 falls onto the diode turnover block 35. The diode discharging device 2 returns to its original position to block the bottommost columnar diode in the diode storage device 1. Then, the diode turnover block 35 moves to the diode pin stamping mechanism 4. The diode pin stamping mechanism 4, in conjunction with the diode turnover block 35, cuts the pins of the columnar diode. After cutting, the diode turnover block 35 moves to the diode unloading mechanism 5. The diode unloading mechanism 5 removes the columnar diode from the diode turnover block 35 for unloading. In this way, the device can automatically cut the pins of columnar diodes, achieve precise control of the pin size of columnar diodes, and improve the production efficiency of columnar diodes.

[0040] In this embodiment, the diode storage device 1 includes a support body 11 and a receiving body 12 mounted on the support body 11. The receiving body 12 has a receiving groove 13 that is open at both the top and bottom. The front wall of the receiving groove 13 has a recess 14 that is open at the top, and the rear wall of the receiving groove 13 has a notch 15 that is open at both the top and bottom. The bottom of the front wall of the receiving groove 13 has two through holes 16. The columnar diode includes a column and leads on both sides. The column is located in the recess 14 and the notch 15, and the leads are located in the receiving groove 13, thus realizing the placement of the columnar diode.

[0041] In this embodiment, the diode feeding device 2 includes a pad 21 and a diode feeding cylinder 22 mounted on the pad 21. The output shaft of the diode feeding cylinder 22 is connected to a mounting block 23. Two diode limiting pins 24 are connected to the mounting block 23. The two diode limiting pins 24 can pass through two through holes 16 and enter the receiving body 12. The diode limiting pins 24 support the pins on both sides of the lowest columnar diode in the diode storage device 1. A diode detection sensor 25 is provided on the mounting block 23. The diode detection sensor 25 can detect whether there is a columnar diode on the diode turnover block 35.

[0042] In practical use, the diode limiting pin 24 supports the pins on both sides of the lowest columnar diode in the diode storage device 1, thereby blocking the columnar diode. When the diode storage cylinder 22 retracts, the lowest columnar diode falls onto the diode turnover block 25. Then, the diode storage cylinder 22 extends to continue blocking the lowest columnar diode in the diode storage device 1. When the diode detection sensor 25 detects that there is a columnar diode on the diode turnover block 35, the control system controls the diode lateral turnover mechanism 3 to move the diode turnover block 35 to below the diode pin stamping mechanism 4.

The bottom end of the guide rod 46 is connected to a pressure plate 44, and the two punches 43 are located on the left and right sides of the pressure plate 44.

[0045] In this embodiment, a support base 7 is provided for mounting and fixing the stamping cylinder 41. When cutting the pins, the stamping cylinder 41 drives the stripping fixture 42 to move downward. The pressure plate 44 first contacts and limits the columnar diode. Then the stamping cylinder 41 continues to press down. At this time, due to the presence of the spring 45, the spring 45 contracts and the pressure plate 44 will no longer move downward. The stripping fixture 42 drives the punch 43 to move downward. The punch 43 cuts the pins of the columnar diode downward.

[0046] In this embodiment, the diode feeding mechanism 5 includes a vertical action cylinder 51 and a diode feeding channel transverse movement cylinder 54. The vertical action cylinder 51 is mounted on the support base 7, and a diode clamping device 53 is connected to the bottom end of the vertical action cylinder 51. The diode clamping device 53 can clamp columnar diodes, and the diode feeding channel transverse movement cylinder 54 can drive the diode feeding channel 55 to move back and forth.

[0047] After the columnar diode leads are cut, the diode turnover block 35 moves to below the diode unloading mechanism 5. The vertical action cylinder 51 drives the diode clamping device 53 to move downward. The diode clamping device 53 clamps the cut columnar diode. Then, the diode unloading channel transverse movement cylinder 54 drives the diode unloading channel 55 to move below the vertical action cylinder 51. The diode clamping device 53 releases the columnar diode, and the columnar diode is discharged through the diode unloading channel 55, thereby realizing the unloading.

[0048] In this embodiment, a vertical cylinder mounting base 52 is provided on the support base 7, and the vertical cylinder 51 is mounted on the vertical cylinder mounting base 52. The vertical cylinder mounting base 52 is provided in this embodiment for mounting the vertical cylinder.

The fixing plate is connected to the diode unloading channel 55. The output shaft of the diode unloading channel transverse cylinder 54 is connected to the fixing plate. In this embodiment, the transverse cylinder mounting base 56 is provided to mount the diode unloading channel transverse cylinder 54. In actual use, the diode unloading channel transverse cylinder 54 drives the fixing plate to move, thereby driving the diode unloading channel 55 to move.

[0050] In this embodiment, the diode lateral rotation mechanism 3 includes a servo protective cover 31, a servo motor 33, and a diode lateral rotation slide rail 37. The servo motor 33 is disposed inside the servo protective cover 31, and a lead screw 32 is connected to the output shaft of the servo motor 33.

The diode rotation block 35 is connected to the diode transverse rotation slider 36, and the lead screw 32 passes through the diode rotation block 35 and is threadedly connected to the diode rotation block 35.

[0052] In this embodiment, the servo motor 33 drives the lead screw 32 to rotate, which, together with the diode turnover block 35, the diode transverse turnover slider 36 and the diode transverse turnover slide rail 37, forms a lead screw structure, driving the diode turnover block 35 to move back and forth.

[0053] In this embodiment, a servo motor mounting base 34 is provided on the base plate 6, and the servo motor 33 is mounted on the servo motor mounting base 34. The servo motor mounting base 34 is provided in this embodiment for mounting the servo motor 33.

[0054] In this embodiment, the diode turnover block 35 has the following shape: Figure 12 As shown, the top wall has a column placement slot, with openings on both the front and rear sides of the column placement slot, and pin placement slots are provided on the left and right side walls of the column placement slot.

[0055] After the columnar diode is placed on the diode turnover block 35, the column is located in the column placement slot and the pin is placed in the pin placement slot. The pins that exceed the length are cut off on the left and right sides of the diode turnover block 35. After cutting, the diode clamping device 53 can clamp the columnar diode from the front and rear openings.
