[0030] See also Figures 1 to 4 The present invention provides a technical solution: a junction box removal device and method for a crystalline silicon photovoltaic module, comprising a frame 1, a crushing mechanism 2, a feeding mechanism 3 and a cutting mechanism 4, wherein the crushing mechanism 2 is fixed on the frame 1, the feeding mechanism 3 is set at the entrance of the crushing mechanism 2, the cutting mechanism 4 is set at the entrance of the feeding mechanism 3, the cutting mechanism 4 comprises a workbench 41, a wire management frame 42, a cutter assembly 43 and a wire assembly 44, the wire management frame 42 is fixed on the workbench 41, the cutter assembly 43 is set on the upper side of the wire management frame 42, and the wire assembly 44 is set on the discharge side of the wire management frame 42;

[0031] The whole line assembly 44 includes a sliding base plate 441, a clamping plate 442, a group of lifting cylinders 443, a group of first electric push rods 444, a first push plate 445, a driving module 446 and a recycling box 447, wherein the driving module 446 is arranged on the workbench 41, the sliding base plate 441 is arranged at the driving end of the driving module 446, the movable end of the lifting cylinder 443 is connected to the sliding base plate 441, the clamping plate 442 is fixedly connected to the lifting cylinder 443 and has an empty groove, the first electric push rod 444 is arranged on the clamping plate 442, the first push plate 445 is connected to the driving end of the first electric push rod 444 and matches the empty groove of the clamping plate 442, a discharge trough 411 is opened on one side of the workbench 41, the recycling box 447 is arranged on the lower side of the discharge trough 411, and an empty groove is opened on the sliding base plate 441.

[0032] In actual operation, after the cable of the junction box is placed on the surface of the sliding base plate 441, the lifting cylinder 443 drives the clamping plate 442 to move down to the surface of the cable and clamp it. During this process, the first push plate 445 shrinks in the empty groove of the clamping plate 442. After clamping the cable, the sliding base plate 441 is driven by the driving module 446 to move the clamping plate 442 backward for a distance to tighten the cable as much as possible. When the cable is cut off, the sliding base plate 441 moves to the upper side of the discharge trough 411, and the clamping plate 442 is lifted up to contact the restriction on the cable. The first electric push rod 444 drives the first push plate 445 to push the cables on the surface of the sliding base plate 441 into the recycling box 447 for unified collection.

[0033] It should be noted that: in order to improve stability, the tangent mechanism 4 can be connected and fixed to the frame 1 through a number of brackets; the drive module 446 is preferably but not limited to a motor, pulley drive and screw drive structure; a switch structure can be provided at the bottom of the recovery box 447 to collect cables.

[0034] A knife groove is provided in the middle of the cable management frame 42 , and a plurality of wire grooves are provided at intervals on the upper side, wherein the wire groove is used to place cables, and the knife groove is used to accommodate the blade of the cutting knife assembly 43 .

[0036] In actual operation, in the initial state, the lifting plate 432 is lifted to the highest position, and the cutter 434 is also located on the upper side of the through slot. However, when cutting is required, the second electric push rod 433 drives the lifting plate 432 to drive the cutter 434 to move downward, and the cutter 434 will cut the cable when it moves down to the bottom of the knife slot.

[0037] The feeding mechanism 3 includes a feeding bin 31, a roller assembly 32, a driving screw 33, a second push plate 34, a guide plate 35, a plurality of knife plates 36 and a pulley drive group 37, wherein the roller assembly 32 is arranged on the side wall of the feeding bin 31 for assisting feeding, the driving screw 33 is rotatably arranged on the upper surface of the feeding bin 31, the second push plate 34 is sleeved on the driving screw 33 and threadedly matched therewith, the guide plate 35 is fixed in the feeding bin 31, the knife plates 36 are arranged at intervals in the feeding bin 31 for preliminarily separating the junction box body, and the pulley drive group 37 is arranged in conjunction with the driving screw 33 for driving the driving screw 33 to rotate.

[0038] In actual operation, the drive screw 33 is driven to rotate by the pulley drive group 37, thereby driving the second push plate 34 to move, and the junction box body with the cable cut off is pushed into the silo 31, and is initially separated by the knife plate 36.

[0039] It should be additionally explained that the roller assembly 32 is composed of a plurality of rollers and a pulley transmission structure for driving the rollers to rotate.

[0040] The crushing mechanism 2 includes a crushing knife group 21 , a driving assembly 22 and a screening bin 23 , wherein the crushing knife group 21 is mounted in the screening bin 23 , and the driving assembly 22 is connected to the crushing knife group 21 .

[0041] The specific implementation methods are as follows:

[0042] Step 1: Loading, the operator places a certain number of junction boxes on the workbench 41, and places the cable parts in the corresponding cable troughs on the cable management rack 42 in sequence;

[0043] Step 2: Tighten. The cable assembly 44 drives the clamping plate 442 to move down to the cable surface and clamp it. The driving module 446 drives the clamping plate 442 to move back a distance to tighten the cable.

[0044] Step 3: Cutting, the cutter assembly 43 drives the cutter 434 to move downward, and the cutter 434 cuts the cables of each junction box in the process of moving to the knife slot, and then moves upward to the initial state;

[0045] Step 4: Cable recovery, the driving module 446 drives the clamping plate 442 and the sliding bottom plate 441 to move back to the upper side of the discharge chute 411, the clamping plate 442 moves up to release the restriction on the cable, and the first electric push rod 444 drives the first push plate 445 to push the cable on the surface of the sliding bottom plate 441 into the recovery box 447;

[0046] Step 5: Pre-treatment of the box body. The pulley drive group 37 drives the driving screw 33 to rotate, so that the second push plate 34 is pushed toward the feeding bin 31. The junction box body on the workbench 41 is pushed into the feeding bin 31. Under the pressure of the second push plate 34, it is pre-cut by the knife plate 36 to reduce the overall volume and enters the crushing mechanism 2 with the help of the roller assembly 32.

[0047] Step 6: crushing the box body. After the junction box body enters the crushing mechanism 2, the fragile plastic box body is quickly crushed to a suitable size, and is screened in the screening bin 23 and collected uniformly;

[0048] Step 7: The hard-to-crush parts in the junction box will continue to accumulate on the screen surface of the screening bin 23. After a certain period of time, the bin can be opened by personnel for unified processing.

[0049] Furthermore, on the basis of the above technical solution, in order to avoid the situation where the cutting blade 434 becomes blunt or damaged after long-term use and cannot cut the cable at one time, a force sensing module can be provided on the clamping surface of the clamping plate 442 to record the pulling state of the cable. Specifically, in step 2, when the clamping plate 442 moves down to the surface of the cable, the tension sensing module detects a continuously increasing pressure from the initial state of no external force, and the pressure signal is a long strip signal arranged at intervals, and the number of strips represents the number of cables clamped. Because the thickness of the cables is different, the magnitude of the force detected is also different. Similarly, when the clamping plate 442 presses the cable, the force signal detected by the force sensing module remains unchanged. Note that the clamping plate 442 is not completely pressed at this time, and the cable can be pulled by external force. When the clamping plate 442 moves back to tighten the cable, the force sensing module determines the tension state of each cable according to the change of the force signal. If the part between the clamping side of the cable and the junction box has been tightened, when the clamping plate 442 moves back, the cable that has reached the limit state will be pulled out a distance. At this time, the force sensing module can detect an obvious pulling force signal. If the part between the clamping side of the cable and the junction box is still In the relaxed state, when the clamping plate 442 moves backward, the force sensing module will not detect an obvious pulling force signal until each detection unit detects an obvious pulling force signal, that is, the cable is completely tightened, which means to ensure that the cutter assembly 43 can cut the cable as completely as possible, thereby improving the cable recovery rate. At the same time, the cable in the taut state also reduces the difficulty of cutting. After being fully tightened, the clamping plate 442 completely clamps the cable to avoid being affected by the cutting force of the cutter assembly 43, resulting in incomplete cutting. In step three, during the process of the cutter 434 moving down to cut the cable, the force sensing module can detect the external tension signal of each cable, which is the pulling force on the cable when the cutter 434 moves down. If the cable is completely cut, the corresponding tension signal message is sent. If the cable is not completely cut, the tension signal still exists. The tension sensing module can judge the cable cutting state according to the change of the force signal in this process. For the cable that is completely cut, a secondary cutting signal can be issued, and the cutter assembly 43 performs secondary cutting. If it is still not completely cut, a reminder can be issued to notify the staff to check the cutter 434 itself.

The pulley drive assembly (37) drives the driving screw (33) to rotate, so that the second push plate (34) is pushed toward the feed bin (31). The junction box body on the workbench (41) is pushed into the feed bin (31). Under the pressure of the second push plate (34), the box body is pre-cut by the knife plate (36) to reduce the overall volume and then enters the crushing mechanism (2) with the help of the roller assembly (32). Step 6: crushing the box body. After the junction box body enters the crushing mechanism (2), the fragile plastic box body is quickly crushed to a suitable size, and then screened through the screening bin (23) and collected uniformly; Step 7: The hard-to-crush parts in the junction box will continue to accumulate on the screen surface of the screening bin (23). After a certain period of time, personnel will open the bin and process them uniformly; In order to avoid the situation where the cutting blade (434) becomes blunt or damaged after long-term use and cannot cut the cable in one go, a force sensing module is provided on the clamping surface of the clamping plate (442) to record the pulling state of the cable. In step 2, when the clamping plate (442) moves down to the surface of the cable, the force sensing module detects a continuously increasing pressure from the initial state of no external force, and the pressure signal is a long signal arranged at intervals, and the number of bars represents the number of clamped cables. Because the thickness of the cables is different, the magnitude of the force detected is also different. When the clamping plate (442) presses the cable, The force signal detected by the force sensing module remains unchanged. Note that the clamping plate (442) is not completely tightened at this time, and the cable is pulled by external force. When the clamping plate (442) moves backward to tighten the cable, the force sensing module determines the tension state of each cable according to the change in the force signal. If the part between the cable clamping side and the junction box has been tightened, then when the clamping plate (442) moves backward, the cable that has reached the limit state will be pulled out a distance. At this time, the force sensing module can detect an obvious pulling force signal. If the part between the cable clamping side and the junction box is still in a loose state, then the clamping plate When (442) moves backward, the force sensing module will not detect obvious pulling force signals until all detection units detect obvious pulling force signals, which means that the cable is completely tightened. This ensures that the cutter assembly (43) can cut the cable more completely, thereby improving the cable recovery rate. At the same time, the taut cable also reduces the difficulty of cutting. After being fully tightened, the clamp (442) completely clamps the cable to prevent the cutter assembly (43) from sliding or moving due to force when cutting downward, resulting in incomplete cutting. In step three, the cutter (434) moves downward to cut. During the process of cutting the cables, the force sensing module can detect the tension signal generated by each cable when the cutter (434) moves downward. If the cable is completely cut, the corresponding tension signal disappears. If the cable is not completely cut, the tension signal still exists. The force sensing module can judge the cutting state of the cable according to the change of the force signal during this process. For the cable that is completely cut, a secondary cutting signal will be issued to make the cutter assembly (43) perform a secondary cutting. If the cable is still not completely cut, a reminder will be issued to notify the staff to check the cutter (434) itself.
