Description

Technical Field

[0001] The present invention relates to the production process of solar panels, specifically to glass gluing equipment and an automated processing system for photovoltaic glass panels. Background Art

[0002] Photovoltaic glass is composed of glass, solar cells, film, back glass, special metal wires, etc. By sealing solar cells in the middle of a piece of glass and a piece of back glass through film and laminating them into solar cells, it can generate electricity using solar radiation and has a special glass with relevant current lead-out devices and cables.

[0003] Reference document CN218502559U, a butyl glue coating device, records a gluing device on a glass plate to solve the problem of uneven gluing. However, the reference document does not have a detection component for the relevant process and cannot perform process treatment after detecting unqualified products, so manual feeding and detection are required, resulting in low efficiency overall.

[0004] The existing technology urgently needs a complete set of automated equipment to improve production efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to solve the automation problems of power generation detection of the glass gluing equipment for photovoltaic glass panels and material diversion processing of the detection results in the prior art.

[0006] To solve the above technical problems, the following technical solutions are provided:

[0007] Glass gluing equipment, the glass gluing equipment includes a second frame, a conveyor line and a light detection platform. There are two groups of the second frames and a compound three-coordinate manipulator is installed on the top. A glass gluing end is installed on the compound three-coordinate manipulator. The light detection platform includes an external light source and a current measurement component. The external light source is suitable for being installed at the bottom of the conveyor line to irradiate the wiring of the photovoltaic glass panel upward. The current measurement component includes fixing plates on both sides of the conveyor line. A lifting cylinder is installed on the side of the fixing plate facing away from the conveyor line. The output end of the lifting cylinder is installed with an upper clamping plate. A metal contact is installed at the bottom of the upper clamping plate. A lower clamping plate is installed on the side of the fixing plate facing the conveyor line. The upper clamping plate and the lower clamping plate are suitable for clamping on the wiring of the photovoltaic glass panel and conducting current detection through the metal contact with the wiring.

[0008] Automated processing system for photovoltaic glass panels, including:

[0009] The cable placement equipment is equipped with a universal positioning mechanism, a three-coordinate robot, and a multi-axis robot arm. The universal positioning mechanism is suitable for blocking and fixing the photovoltaic glass panel; the multi-axis robot arm is suitable for laying the cable on the photovoltaic glass panel; the three-coordinate robot arm is equipped with a follow-up glue application terminal and a cable welding terminal for cable placement and welding;

[0010] It also includes glass gluing equipment;

[0011] Wire bending equipment, which is suitable for bending and gluing wires;

[0012] A junction box installation device, suitable for installing a junction box on a photovoltaic glass panel and applying solder paste;

[0013] Wire box welding equipment, which is suitable for welding the junction box and the cable;

[0014] The glue injection and cover-laying device is suitable for injecting glue into the junction box and installing the end cover on the junction box.

[0015] In a further technical solution, the universal positioning mechanism includes a limit switch, a lifting cylinder, a blocking cylinder, a clamping cylinder and a suction platform. The lifting cylinder is suitable for being installed at the bottom of the conveyor line and connected; two groups of suction platforms are installed on both sides of the conveyor line, and a suction cup is installed on the top of the suction platform; the clamping cylinder is installed at the lower part of the suction platform, and multiple groups are provided on the outside of the suction platform; a fixed column is installed at the output end of the clamping cylinder, and is in an extended state when the photovoltaic glass panel has not passed the limit switch.

[0016] Specifically, the universal positioning mechanism is used to secure the glass sheet during each process step. Therefore, its structure should be simple and must provide a secure, clamping action. This invention achieves a lifting effect on the conveyor line by installing a lifting cylinder at the bottom of the conveyor line. The output end of the lifting cylinder connects the plate to the bottom frame of the conveyor line, achieving a telescopic lifting effect. Suction cups on the suction platform absorb the bottom of the glass sheet. The retraction of the clamping cylinder secures both sides of the glass sheet.

[0017] In a further technical solution, in step 1, the cable placement equipment includes a frame 1 located on both sides, a three-coordinate robot is installed on the frame 1, and a conveyor line 1 and a conveyor line 2 are respectively installed between the frame 1 on both sides. The photovoltaic glass panel is suitable for being transferred from the conveyor line 1 to the conveyor line 2. The conveyor line 1 and the conveyor line 2 are both installed with a universal positioning mechanism, and the universal positioning mechanism is suitable for blocking and fixing the photovoltaic glass panel;

[0018] The three-coordinate manipulator includes a column X-axis, a crossbeam Y-axis, and a lifting Z-axis. There are two sets of column X-axes, which are arranged in parallel on both sides of the first rack. There are two sets of crossbeam Y-axes, which are installed in parallel between the two sets of column X-axes. A connecting plate is installed between the two sets of crossbeam Y-axes. A lifting Z-axis is installed on the connecting plate. A counterweight is installed on one side of the lifting Z-axis. A follow-up glue application end is installed at the bottom of the lifting Z-axis.

[0019] First blocking and fixing: In the fixing step 1, when the limit switch detects the passage of the photovoltaic glass plate, the output end of the blocking cylinder rises to block the forward movement of the photovoltaic glass plate; at the same time, the output end of the lifting cylinder retracts downward, driving the first conveyor line or the second conveyor line to descend and placing the photovoltaic glass plate on the suction platform. Meanwhile, the output end of the synchronous clamping cylinder contracts inward to clamp the photovoltaic glass plate, and the suction cups on the suction platform firmly adsorb the photovoltaic glass plate; the follow-up glue application end coats butyl glue on the photovoltaic glass plate according to the set path.

[0020] Specifically, there are two sets of conveyor lines on the wire arrangement and mounting equipment. The actions of blocking, clamping, and adsorption are realized through the general positioning mechanism on the first conveyor line, and the glue application action is realized through the three-coordinate manipulator. Among them, toothed plates and driving motors are arranged on both the column X-axis and the crossbeam Y-axis of the three-coordinate manipulator. A gear is installed at the output end of the driving motor to mesh with the toothed plate to achieve reciprocating movement in a single direction.

[0021] In a further technical solution, a wire arrangement welding end is installed on the outer side of the column X-axis close to the second conveyor line. Multi-axis robotic arms are installed on both sides of the first rack. The output end of the multi-axis robotic arm is a rotating end, and a grasping sub-end and a paste applying sub-end are respectively installed on the rotating end; Metal wire arrangement bins are installed on both sides of the multi-axis robotic arm. The bottom of the metal wire arrangement bin is connected to the corresponding first rack, and a wire arrangement is installed at the top of the metal wire arrangement bin.

[0022] Second blocking and fixing: When the photovoltaic glass plate is on the second conveyor line, it is fixed by the general positioning mechanism. Then, the grasping sub-end of the multi-axis robotic arm grabs the wire arrangement in the metal wire arrangement bin and places it at the glue application position of the follow-up glue application end and presses it downward; Subsequently, the rotating end rotates to drive the paste applying sub-end to apply solder paste to the wire arrangement, and then, the wire arrangement welding end welds the position where the solder paste is applied.

[0023] Specifically, the multi-axis robot places and presses the wire arrangement from the metal wire arrangement bin at the aforementioned glue application position. The wire arrangement welding end is fixed to a set of column X-axes of the three-coordinate manipulator, and the welding end welds the wire arrangement on the second conveyor line downward.

[0024] In a further technical solution, in step two, the glass gluing device includes a second rack, a compound three-coordinate manipulator, a light detection platform, a lifting and reversing platform, a qualified product conveyor line, and a recycling branch line; there are two groups of the second racks, and a conveyor line is installed between the two groups of the second racks. A light detection platform is installed at the lower end of the conveyor line, and a general positioning mechanism is installed outside the conveyor line;

[0025] The light detection platform includes an external light source and a current measurement component. The external light source is adapted to irradiate the photovoltaic glass plate from the bottom where the conveyor line is installed;

[0026] The current measurement component includes fixing plates located on both sides of the conveyor line. A lifting cylinder is installed on the side of the fixing plate facing away from the conveyor line. The output end of the lifting cylinder is adapted to stretch up and down and is installed with an upper clamping plate. A lower clamping plate is installed on the side of the fixing plate opposite to the conveyor line. The upper clamping plate and the lower clamping plate are adapted to clamp the end of the wire arrangement of the photovoltaic glass plate;

[0027] The compound three-coordinate manipulator has the same structure as the three-coordinate manipulator;

[0028] The lifting and reversing platform includes a conveyor line, a detection switch, a side positioning mechanism, a lifting mechanism, and a side pushing mechanism. There are two groups of both the detection switch and the side positioning mechanism. The detection switch is adapted to detect the passing of the photovoltaic glass plate and control the side positioning mechanism. The side positioning mechanism is adapted to block the photovoltaic glass plate. The output end of the lifting mechanism is adapted to drive the conveyor line to move up and down. The side pushing mechanism is adapted to push the photovoltaic glass plate; the height of the recycling branch line is lower than the height of the qualified product conveyor line.

[0029] Specifically, overall, the glass gluing device is fixed through a general positioning device. First, the welding effect is detected by the light detection platform. After the normal wire arrangement is irradiated with light, a weak current will be generated inside it based on the photovoltaic effect. The current detection is carried out through the weak current. The current measurement component inside it includes detection jaws. By clamping the upper and lower ends of the wire arrangement, the closure of the current loop is achieved. When a weak current appears, the current measurement component will react.

[0030] The lifting and reversing platform is for the shunt processing of the detection results of the light detection platform. For qualified products, they can be directly transferred to the next process equipment. For unqualified products, they will be blocked by the side positioning mechanism and the height will be lowered through the lifting mechanism. Therefore, the recycling branch line in the design is at a different height from the normal product passing conveyor line of the lifting and reversing platform. When unqualified products appear, the lifting mechanism works. The side pushing mechanism pushes the unqualified products onto the recycling branch line. The unqualified products on the recycling branch line need to be subjected to subsequent repeated detection and repair.

[0031] In a further technical solution, after passing through Step 3, the photovoltaic glass plates are combined with the wire harness and the backplane glass respectively to form a photovoltaic panel;

After being folded twice, the wire harness is in a "C" shape, and its top is parallel to the photovoltaic panel;

[0035] The label picking and placing mechanism includes a label picking multi-axis robot, a compound vision frame, and an automatic label feeder;

[0036] A label picking table is installed on one side of the automatic label feeder facing the conveyor line. The automatic label feeder is suitable for conveying labels to the label picking table;

[0037] There are two sets of the compound vision frames, which are respectively located on the two sets of the third racks. Two sets of vision modules are respectively arranged on the compound vision frames. One set of vision modules is located on the conveyor line and is suitable for detecting the photovoltaic panel, and the other set of vision modules is located above the label picking table. The multi-axis robot is suitable for tearing the label and pasting it on the wire harness, specifically, the top of the wire harness is parallel to the outer side of the glass plate;

[0038] The glue applying mechanism includes a single set of cross beam X-axis, translation Y-axis, and vertical Z-axis. The cross beam X-axis is installed with a transverse slide rail. One end of the translation Y-axis is installed on the transverse slide rail at the top of the cross beam X-axis. A longitudinal slide rail is installed on the translation Y-axis. The top of the vertical Z-axis is installed on the translation Y-axis. The vertical Z-axis is a lifting axis along the vertical direction. A glue applying end is installed at the bottom of the vertical Z-axis. The glue applying end is suitable for applying glue to the photovoltaic panel.

[0039] Specifically, the wire harness is folded to facilitate the subsequent component installation and distinguish the male and female connectors of the photovoltaic panel. The folding part is realized by two consecutive action cylinders for folding, and the label pasting is realized by a multi-axis robot.

[0041] The dual-end three-axis manipulator includes two groups of parallel track X-axes. The two groups of track X-axes are installed on both sides of the fixed platform, the buffer platform, and the push garage. The fixed platform, the buffer platform, and the push garage are sequentially arranged within the two groups of track X-axes;

[0042] Two groups of translation Y-axes are installed between the two groups of track X-axes. A tray grabbing gripper is installed on the translation Y-axis close to the push garage, and a rotating end is installed on the other group of translation Y-axes. The rotating gripper includes a box-grabbing end and a paste-applying end;

[0043] The push garage includes a bottom frame. There are multiple groups of the bottom frames and they are equally spaced. A tray cart is installed inside the bottom frame. A tray is placed on the tray cart, and a junction box is placed on the tray.

[0044] Specifically, by setting up the push garage to realize manual material transportation, compared with the single-person feeding problem in the prior art. In the present invention, a tray cart is provided. There are 12 partition columns on the tray cart to form four groups of areas for palletizing trays, and more than one group of junction boxes can be placed on the tray. The junction box installation device simplifies the working steps. By setting up the buffer platform, the tray grabbing gripper on one group of manipulators fixes the placement position of the tray, and the box-grabbing end on the other group of manipulators takes out the junction box and places it at the specified position of the photovoltaic panel, and injects solder paste along the position of the junction box.

[0045] In a further technical solution, the junction box welding device includes a light detection platform, a junction box welding mechanism, a lifting and reversing platform, and a recycling branch line; the junction box welding device has the same structure as the light detection platform, the lifting and reversing platform, and the recycling branch line in the glass gluing device;

[0046] The junction box welding mechanism includes a three-axis coordinate platform. The three-axis coordinate platform includes a toothed plate, a moving plate, and a driving motor. The output end of the driving motor faces downward and is installed with a gear meshing with the toothed plate; the driving motor is installed on the moving plate and drives the moving plate to move along the toothed plate. A vision module and a junction box welding end are respectively installed on both sides of the moving plate. The vision module is adapted to detect the position of the photovoltaic panel, and the junction box welding end is adapted to weld the junction box on the photovoltaic panel.

[0047] Specifically, the overall structure of the junction box welding mechanism of the present invention is similar to the previous structure. A universal positioning mechanism is again used to fix the junction box, and the junction box welding end is used to achieve welding. The welding part here is to weld the internal wiring of the junction box to the wiring of the photovoltaic panel, thereby adding equipment to the circuit. The illumination detection platform is again used to detect the illumination circuit of the added junction box.

[0048] In a further technical solution, the glue injection and capping equipment includes a frame four, the frame four is provided with two groups and a conveyor line is installed between them, a universal positioning mechanism is installed on the conveyor line, a double-end three-axis robot is installed between the two groups of the frame four, the double-end three-axis robot includes a crossbeam X-axis, a translation Y-axis and a lifting Z-axis, the translation Y-axis is installed with two groups, each group of the translation Y-axis is installed with a lifting Z-axis, one group of the lifting Z-axis is installed with a cap removal terminal and a vision module, and the other group of the lifting Z-axis is installed with a glue injection terminal; the vision module is located on the side of the corresponding lifting Z-axis opposite to the glue injection module;

[0049] A pickup mechanism is installed on one of the four frames, and the pickup mechanism includes a multi-tube silo, a cap-removing robot, a hook-cap component, and a clearance component.

[0050] The glue injection end injects glue on the photovoltaic glass panel, and the cap removal end places the end cap on the glue injection position.

[0051] The subsequent frame gluing is to inject glue into the inside of the aluminum frame. The frame assembly machine installs the glued aluminum frame panels around the photovoltaic panel, extrudes and closes them into shape, and then produces a complete photovoltaic panel.

[0052] The position of the pre-series cable may not be unique, that is, multiple cables may be installed on one glass plate, which is set according to the needs of the manufacturer.

[0053] Compared with the prior art, the present invention can achieve the following technical effects:

[0054] The present invention as a whole is a highly automated device for producing photovoltaic glass panels, which has excellent effects such as high integration, high efficiency, and high quality.

[0055] The general positioning mechanism of the present invention is used to fix the glass plate in each process step, and the structure is simple. The present invention realizes the lifting effect of the conveyor line by installing a lifting cylinder at the bottom of the conveyor line. The output end of the lifting cylinder is connected to a connecting plate member and is connected to the bottom frame of the conveyor line to achieve the effect of telescopic drive for lifting. The suction cups on the suction platform are used to adsorb the bottom of the glass plate. The clamping of both sides of the glass plate is realized by the retraction effect of the clamping cylinder.

[0056] There are two sets of conveyor lines on the wire arrangement and mounting device of the present invention. The general positioning mechanism on conveyor line one is used to realize the actions of blocking, clamping and adsorption, and the gluing action is realized by a three-coordinate manipulator. The wire arrangement is placed and pressed at the aforementioned gluing position by a multi-axis robot that arranges the wire from the metal wire arrangement bin. The end of the wire arrangement welding faces downward to weld the wire arrangement on conveyor line two.

[0057] For the glass gluing device of the present invention, fixation is achieved through a general positioning device. First, the welding effect is detected by a light detection platform. After a normal wire arrangement is irradiated with light, a weak current will be generated inside it based on the photovoltaic effect. The current detection is carried out through the weak current. The current measurement component inside it includes detection jaws. By clamping the upper and lower ends of the wire arrangement, the closure of the current loop is realized. When a weak current appears, the current measurement component will react. The detection steps are simple and highly efficient, and do not require complex structures for detection. Most of the existing technologies are manual detection of the on-off of photovoltaic glass plates, resulting in low efficiency.

[0058] For the wire arrangement bending device of the present invention, bending is achieved through two sets of continuous action cylinders. The longitudinal cylinder bends it into an "L" shape, and the transverse cylinder bends it into a "C" shape. Then, a multi-axis robot is used to realize label pasting, and the steps are programmed without the need for human intervention.

[0059] The wire box installation device of the present invention realizes material stacking by setting up a push garage. In the present invention, a tray cart is set up. There are 12 sets of partition columns on the tray cart to form four groups of areas for palletizing trays, and more than one set of junction boxes can be placed on the tray. The wire box installation device simplifies the working steps. By setting up a buffer platform, the tray gripping hand on one set of mechanical arms fixes the placement position of the tray, and the box-taking end on the other set of mechanical arms takes out the junction box and places it at the designated position on the photovoltaic panel, and injects solder paste along the position of the junction box.

[0060] The overall structure of the wire box welding mechanism of the present invention is similar to the previous structure. The general positioning mechanism is used again to fix, and the wire box welding end realizes the welding of the junction box. The welding part here is to weld the internal circuit of the junction box to the wire arrangement of the photovoltaic panel, realizing an increase in equipment on the circuit. The light detection platform is used again to detect the light circuit of the added junction box.

[0061] The material delivery of the end cap is achieved by setting up a multi-tube silo, the end cap is taken out from the silo tube by a hook cover component, and the end cap is transported by a cover removal robot and a clearance component. The glue is injected according to the set path through the glue injection end, and then placed and pressed on the glue injection position by the cover removal end. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0093] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0094] The photovoltaic glass plate of the present invention is based on a perovskite solar cell. Before entering the wire arranging and mounting equipment, perovskite liquid has been set in the photovoltaic glass plate, which is considered to be able to generate current. A perovskite solar cell is a solar cell that uses an organic metal halide semiconductor of the perovskite type as a light-absorbing material, belonging to the third generation of solar cells and also called a new concept solar cell.

[0095] When receiving sunlight irradiation, the perovskite layer first absorbs photons to generate electron-hole pairs. Due to the difference in the exciton binding energy of the perovskite material, these carriers either become free carriers or form excitons. Moreover, because these perovskite materials often have a low carrier recombination probability and a high carrier mobility, the diffusion distance and lifetime of the carriers are relatively long.

[0096] Then, these un-recombined electrons and holes are respectively collected by the electron transport layer and the hole transport layer, that is, electrons are transported from the perovskite layer to the electron transport layer and finally collected by FTO; holes are transported from the perovskite layer to the hole transport layer and finally collected by the metal electrode. Of course, there are always some carrier losses in these processes, such as the reversible recombination of electrons in the electron transport layer and holes in the perovskite layer, the recombination of electrons in the electron transport layer and holes in the hole transport layer (in the case where the perovskite layer is not dense), and the recombination of electrons in the perovskite layer and holes in the hole transport layer. To improve the overall performance of the battery, these carrier losses should be minimized. Finally, a photocurrent is generated through the circuit connecting FTO and the metal electrode.

[0137] In summary, the preparation process of the photovoltaic glass panel automated processing system includes the following processing steps:

[0138] Step 1: Wire placement: The front-end line body transports the photovoltaic glass panel to the starting point of the wire placement equipment 100, passing through the conveyor line 101 and the conveyor line 2 102. The conveyor line 101 and the conveyor line 2 102 are both equipped with a universal positioning mechanism 700. The panel undergoes two blocking and fixing operations in sequence: the first blocking and fixing is for gluing, and the second blocking and fixing is for patching and welding.

[0139] After completion, it falls down and is transferred to the external equipment via the second conveyor line 102 to complete the overall coating;

[0140] Block and fix at one time: In step one, when the limit switch 701 detects that the photovoltaic glass panel has passed, the output end of the blocking cylinder 703 is lifted and blocks the photovoltaic glass panel from moving forward; at the same time, the output end of the lifting cylinder 702 retracts downward, driving the conveyor line 101 or the conveyor line 2 102 to descend and place the photovoltaic glass panel on the suction platform 705, and the output end of the synchronous clamping cylinder 704 retracts inward and clamps the photovoltaic glass panel, and the suction cup on the suction platform 705 firmly adsorbs the photovoltaic glass panel; the follow-up glue coating end coats butyl glue on the photovoltaic glass panel according to the set path.

[0141] Secondary blocking and fixing: When the photovoltaic glass plate is on the second conveyor line 102, it is fixed by the general positioning mechanism 700. Then, the picking sub-end 1071 of the multi-axis robotic arm 107 picks up the wire harness from the wire harness bin 108 of the metal wire harness, places it at the glue application position of the follow-up glue application end, and presses it down. The wire harness is installed on the photovoltaic glass plate and its end extends out of the photovoltaic glass plate. Subsequently, the end rotates, driving the solder paste application end 1072 to apply solder paste to the wire harness. Then, the wire harness welding end 106 welds the position where the solder paste is applied.

[0142] Step 2, glass glue application: When the photovoltaic glass plate arrives at the glass glue application device 200 after wire harness patchwork;

[0143] Block and fix the photovoltaic glass plate, apply glue evenly around the four edges. The glue application width is 6 - 8 mm and the height is 0.5 mm. The four sides of the photovoltaic glass plate are evenly coated, and butyl glue is coated on the upper end of the wire harness. Then, perform light and current detection on the welding condition of the previous wire harness;

[0144] For qualified photovoltaic glass plates, the compound coordinate manipulator 201 performs glue application operations around the edges of the photovoltaic glass plate, and then continues to be conveyed through the lifting and reversing platform and leaves the glass glue application device 200;

[0145] For unqualified photovoltaic glass plates, they are conveyed to the lifting and reversing platform, blocked, lowered, and laterally pushed to the recycling branch line;

[0146] Step 3, laying the glue film, covering with the backplane glass and laminating and heating; After the photovoltaic glass plate is combined with the wire harness and the backplane glass, it becomes the photovoltaic glass plate. The photovoltaic glass plates in Steps 1 to 2 are further panel glass, and when combined with the wire harness and the backplane, they are called the basic photovoltaic panel. Then, bending the wire harness and installing the junction box are the subsequent processing of the photovoltaic panel. The panel glass and the photovoltaic panel are collectively called the photovoltaic glass plate.

[0147] Step 4, wire harness edge folding and positioning: The photovoltaic panel enters the wire harness edge folding device 300. The general positioning mechanism 700 blocks and fixes the photovoltaic panel. The bending mechanism 301 performs two edge folding processes on the wire harness. The picking and placing label mechanism 302 fixes the label on the wire harness. After applying glue, it enters the next working station;

[0148] Step 5, junction box installation: When entering the junction box installation device 400, the general positioning mechanism 700 blocks and fixes the photovoltaic panel. The tray gripper 401 takes out the tray from the push garage 406 and places it on the buffer platform 402. The box picking end 403 takes out the junction box from the tray and places it at the position where glue was applied to the photovoltaic panel in Step 4, and presses it. Then, it rotates to make the solder paste application end 404 apply solder paste into the junction box and enters the next working station;

[0149] Step 6, junction box welding: The photovoltaic panel enters the junction box welding device 500 and is blocked and fixed by the universal positioning mechanism 700. The junction box welding end of the junction box welding mechanism 501 welds the internal wiring of the junction box to the wiring of the photovoltaic panel, and then illuminates and detects the current.

[0150] Step 7, glue injection and upper cover: After entering the glue injection and upper cover equipment 600, the universal positioning mechanism 700 blocks and fixes the photovoltaic panel, and the glue injection terminal 601 injects glue into the junction box. The end cover is taken out from the silo tube through the hook cover component, and the end cover is transported through the cover removal robot and the clearance component; the end cover is pressed on the glue coating position of the junction box. After completing the processing system, the photovoltaic panel is unlocked and leaves the equipment, and the whole processing system is completed.
