Description

Technical Field

[0001] The utility model relates to the technical field of junction box installation equipment, in particular to a junction box installation equipment. Background Art

[0002] In the manufacturing process of photovoltaic modules, it is necessary to install a junction box on the solar panel, align the junction box with the bus bar for plugging and installation, and weld the bus bar on the junction box.

[0003] Generally, there are two types of junction boxes: a wired junction box and a wireless junction box. The wired junction box is usually installed on both sides of the photovoltaic module panel to form an output end, and the wireless junction box is installed in the middle of the photovoltaic module panel to form a current path.

[0004] At present, the assembly of the junction box is usually done manually, and the junction box in the material box is manually transferred to the wiring position on the solar panel, and the junction box is assembled with the wiring on the solar panel. This has a slow assembly efficiency, consumes a lot of manpower, and has a high labor cost. Utility Model Content

[0005] The utility model provides a junction box installation device to solve the technical problems of low installation efficiency and high labor cost in the prior art of manually installing the junction box on a solar cell panel.

[0006] In order to solve the above problems, the utility model provides a junction box installation device adopting the following technical solutions:

[0007] A junction box installation device, comprising:

[0008] A frame, on which a junction box conveying unit, a junction box detection unit, a solar panel conveying unit, a junction box transfer unit and a junction box assembly unit are arranged;

[0009] The junction box conveying unit is used to convey the junction box to the junction box transfer unit;

[0010] The junction box detection unit is used to detect the weight and appearance of the junction box during the process of the junction box being transported by the junction box transport unit;

[0011] A junction box assembly station is provided on the frame, and the solar panel conveying unit is used to convey the solar panel to the junction box assembly station;

[0012] The junction box assembly unit is used to assemble the junction box at the junction box transfer module onto the wiring on the solar cell panel located at the junction box assembly station.

[0013] The beneficial effects of the above technical solution are: using the junction box conveying unit to convey the junction box, using the junction box assembly unit to assemble the junction box, using the installation equipment to replace manual installation of the junction box, realizing the automated assembly of the junction box, and improving the assembly efficiency.

[0014] Further, the junction box delivery unit includes a wired junction box delivery module and a wireless junction box delivery module; the junction box detection unit includes a weight sensor;

[0015] The wired junction box delivery module comprises:

[0016] a feed assembly for supplying a wired junction box;

[0017] The weighing platform is used to place the wired junction box supplied by the feeding assembly, and the weight sensor is installed at the bottom of the weighing platform to detect the weight of the wired junction box on the weighing platform;

[0018] A first transfer assembly, located between the feeding assembly and the weighing platform, is used to transfer the wired junction boxes at the feeding assembly to the weighing platform in sequence;

[0019] A second transfer assembly is located beside the weighing platform and is used to transfer the wired junction box on the weighing platform to the next conveying station when the weight sensor detects that the weight of the wired junction box on the weighing platform is within a set range;

[0020] A wired junction box collection station is used to collect wound wired junction boxes;

[0021] The rejecting mechanism is used to transfer the wired junction box to the wired junction box collection station when the weight sensor detects that the weight of the wired junction box exceeds a set range.

[0022] The beneficial effect of the above technical solution is: by installing a weight sensor at the bottom of the weighing platform, the junction box taken out from the feeding assembly is weighed and detected. If the measured weight of the junction box is within the set range, it means that only one wired junction box has been taken out. If the detected weight of the junction box exceeds the set range, it means that multiple junction boxes are entangled with each other and are taken out together. At this time, the rejection mechanism will reject the multiple wired junction boxes entangled with each other from the weighing mechanism. In this way, the first transfer assembly can be prevented from taking out multiple wired junction boxes entangled with each other from the feeding assembly, and the multiple wired junction boxes entangled with each other are transported to the subsequent junction box assembly station, which affects the assembly of the junction boxes.

[0023] Furthermore, the weighing platform can rotate around a horizontal axis, and a drop channel is provided under the weighing platform. The outlet of the drop channel is connected to the wired junction box collection station, and the rejection mechanism includes a rotating drive component for driving the weighing platform to rotate. The rotating drive component is used to drive the weighing platform to flip up and down when the weight sensor detects that the weight of the wired junction box on the weighing platform exceeds a set range, so that the wired junction box on the weighing platform slides into the drop channel and falls to the wired junction box collection station.

[0024] The beneficial effect of the above technical solution is: when the weight sensor detects that the weight of the wired junction box exceeds the set range, the rotating drive drives the weighing platform to rotate the set angle, so that the weighing platform is tilted, so that the wired junction boxes entangled with each other on the weighing platform can slide from the tilted weighing platform into the blanking channel, and the rejection method is simple, and the rejected wired junction boxes can be collected at the collection station.

[0025] Further, the junction box detection unit includes front and back visual detection cameras;

[0026] The wired junction box delivery module comprises:

[0027] A feeding platform is located beside the weighing platform, and the second transfer component is used to transfer the wired junction box on the weighing platform with a weight within a set range to the feeding platform;

[0028] The material flipping and transferring mechanism is used to grab the wired junction box on the feeding platform and transfer the wired junction box to the next conveying station when the front and back visual inspection cameras detect that the front side of the wired junction box is facing upwards; when the front and back visual inspection cameras detect that the back side of the wired junction box is facing upwards, the wired junction box is flipped over and then transferred to the next conveying station.

[0029] The beneficial effect of the above technical solution is that after the wired junction box is taken out, it is not necessarily in the front-facing position. By setting up front and back visual inspection cameras to detect the front and back placement of the wired junction box, and setting up a material turning and transfer mechanism to flip the wired junction box with the back facing up to the front facing up, problems can be avoided when installing the wired junction box later.

[0030] Furthermore, the junction box transfer unit includes multiple sets of junction box feeding mechanisms;

[0031] The wired junction box delivery unit comprises:

[0032] A material storage conveyor line is located beside the material feeding platform, and the material turning and transferring mechanism is used to transfer the wired junction box facing upward to the material storage conveyor line;

[0033] The third transfer component is located beside the conveying end of the stock conveyor line, and the junction box loading mechanism is located at the conveying end of the stock conveyor line. The third transfer component is used to transfer the wired junction box on the stock conveyor line to the corresponding junction box loading mechanism.

[0034] Furthermore, the stock conveyor line is used to drive the wired junction box to be intermittently conveyed forward, and the conveying end of the stock conveyor line is a material picking position. The junction box detection unit includes an in-place visual detection camera, and the in-place visual detection camera is located above the material picking position. When the in-place visual detection camera detects the wired junction box on the material picking position, the third transfer component transfers the wired junction box to the junction box loading mechanism. When the in-place visual detection camera detects that there is no wired junction box on the material picking position, the stock conveyor line conveys forward a set distance.

[0035] The beneficial effects of the above technical solution are: a visual detection camera is set in place to detect whether there is material at the material picking position on the stock material conveyor line. When material is detected, the position of the material can be determined and the third transfer component can be controlled to transfer it. When no material is detected, the stock material conveyor line continues to convey it forward for a distance. Compared with the method of using sensors to detect whether there is material, the use of an in-place visual detection camera for detection has a wider recognition area and more accurate detection results, which can avoid the situation where the wired junction box at the material picking position is not detected, resulting in the undetected wired junction box falling from the stock material conveyor line as it is conveyed by the stock material conveyor line.

[0036] Furthermore, the wireless junction box delivery module includes:

[0037] A wireless junction box feeding mechanism, used for supplying wireless junction boxes;

[0038] A wireless junction box conveyor line is located beside the wireless junction box feeding mechanism;

[0039] A fourth transfer component is located between the wireless junction box feeding mechanism and the wireless junction box conveying line, and is used to transfer the wireless junction box at the wireless junction box feeding mechanism to the wireless junction box conveying line;

[0040] The conveying end of the wireless junction box conveying line extends to the side of one group of junction box feeding mechanisms, and the third transfer component is used to transfer the wireless junction boxes on the wireless junction box conveying line to the corresponding junction box feeding mechanisms.

[0041] Furthermore, the junction box assembly unit includes:

[0042] A transverse drive mechanism is arranged on the frame, and a transverse output end of the transverse drive mechanism is connected to a moving frame;

[0043] A first lifting drive mechanism is arranged on the movable frame, and a lifting output end of the first lifting drive mechanism is connected to a mounting bracket;

[0044] A grabbing assembly for grabbing the junction box, which is arranged on the mounting bracket, and the grabbing assembly is used to move back and forth between the junction box feeding mechanism and the wiring of the solar panel with the moving frame to grab the junction box to above the wiring of the solar panel, and the first lifting drive mechanism is used to drive the grabbing assembly to move downward with the junction box so that the wiring passes through the jack on the junction box;

[0045] The mounting bracket is provided with a bending and pressing assembly, which includes two horizontally movable bending push plates, the lower ends of which are arranged inclined in a direction approaching each other, and the bending and pressing assembly also includes a pressing block located between the two bending push plates and movable up and down, the two bending push plates are used to extend between the two wires and move away from each other to push and bend the wires passing through the junction box, and the pressing block is used to move downward in the process of the two bending push plates moving away from each other to push and bend the wires so as to press the wires onto the metal welding block of the junction box.

[0046] The beneficial effects of the above technical solution are: the transverse driving mechanism drives the moving frame to move back and forth, driving the grabbing assembly to move back and forth between the wiring of the junction box feeding mechanism and the wiring of the solar cell, so that the grabbing assembly grabs the junction box and transfers the junction box to above the wiring of the solar cell panel, and the first lifting driving mechanism is used to drive the junction box grabbed by the grabbing assembly to move downward, so that the wiring passes through the jack on the junction box, and the bending push plate in the bending and pressing assembly is used to bend the wiring passing through the junction box so that the top of the wiring is folded onto the metal welding block on the junction box, and the pressing block is used to flatten the bent wiring so that the wiring and the metal welding block are more fitted, and the pressing block is located between the two bending push plates. In the process of the two bending push plates moving away from each other and pushing the bent wiring, the pressing block starts to move downward, so that after the bending push plate pushes the wiring to bend, the pressing block can be quickly pressed on the bent wiring, and the actions of bending the wiring and flattening the wiring are more coherent, and the time spent on flattening the wiring is less, thereby improving the installation efficiency of the junction box.

[0047] Furthermore, the bending and pressing assembly also includes a lifting drive connected to the mounting bracket, the output end of the lifting drive is connected to a mounting plate, the pressing block is connected to the bottom of the mounting plate, the mounting plate is also connected to a pushing member, and the pushing member is located above the pressing block;

[0048] The two bent push plates are slidably assembled on the mounting bracket, and the two bent push plates have an inclined sliding surface on one side close to each other, and a V-shaped movable groove is formed between the two sliding surfaces. The pushing member is located in the movable groove and abuts against the two sliding surfaces, and the lifting drive member is used to drive the mounting plate to drive the pressure block and the pushing member to move downward so as to push the two bent push plates to move away from each other while the pressure block is pressed downward.

[0049] The beneficial effects of the above technical scheme are: the driving end of the lifting drive member is connected to the mounting plate, and the pressure block and the pushing member used to drive the two bent push plates away from each other are installed on the mounting plate, so that the lifting drive member drives the mounting plate to move to drive the pressure block and the pushing member to move at the same time, and the pushing member moves downward to push the two pushing surfaces to drive the two bent push plates away from each other, so that the driving end of the lifting drive member only needs to move up and down to simultaneously realize the downward pressure of the pressure block and the movement of the two bent push plates away from each other, the driving method is simple, and the structural arrangement is simple and compact.

[0050] Furthermore, a second lifting drive mechanism is installed on the mobile frame, and a lifting output end of the second lifting drive mechanism is connected to a straightening component, which is located below the grabbing component and the bending and pressing component. The straightening component is used to clamp the wiring to straighten the wiring when the mobile frame moves to the wiring point of the solar panel.

[0051] The beneficial effect of the above technical solution is that the straightening assembly is used to straighten the wiring to a vertical state before the wiring passes through the wiring box, ensuring that the wiring can correspond to the socket on the wiring box and can pass through the socket smoothly. The straightening assembly is connected to the driving output end of the second lifting drive mechanism, and the second lifting drive mechanism can drive the straightening assembly to move up and down, so that when the lateral driving mechanism drives the moving frame to drive the straightening assembly to move back and forth between the wiring of the wiring box feeding mechanism and the wiring of the solar panel, the straightening assembly can be lifted above the wiring to avoid interference between the straightening assembly and the wiring, and before assembling the wiring box, the straightening assembly can be lowered to the wiring to straighten the wiring.

[0071] The following is one embodiment of a junction box installation device provided by the utility model:

[0072] like Figure 1 , Fig.10 and Fig.11 As shown, a junction box installation device is used to transport and assemble a junction box 22. The junction box 22 is divided into a wired junction box and a wireless junction box. The structure of the wired junction box is as follows Fig. 9 As shown. The length direction of the equipment is defined as the left-right direction, and the width direction is the front-to-back direction.

[0078] The junction box detection unit includes a front and back visual inspection camera 61 disposed on the frame 24. Each of the above-mentioned feeding platforms 44 is provided with a storage conveyor line 57 extending in the left and right directions. The above-mentioned material turning and transferring mechanism is used to grab the wired junction box on the feeding platform 44. At the same time, according to the detection results of the front and back visual inspection cameras 61, when the wired junction box is facing up, the wired junction box is first turned over to face up and then transferred to the storage conveyor line 57. When the wired junction box is facing up, the wired junction box is directly transferred to the storage conveyor line 57.

[0089] The three sets of junction box feeding mechanisms are located on the right side of the above-mentioned transverse moving assembly, such as Figure 7 and Figure 8As shown, the terminal box feeding mechanism includes a base 18, a feeding platform 17 and a rotary drive mechanism 19. The base 18 is fixedly mounted on the frame 24, the feeding platform 17 is square, the feeding platform 17 is rotatably assembled on the base 18, and the rotary drive mechanism 19 includes a rotary drive motor, which is in transmission connection with the feeding platform 17. Two groups of clamping assemblies are provided on the feeding platform 17, and the two groups of clamping assemblies are respectively located at two diagonal positions on the feeding platform 17. The clamping assemblies include a clamping drive member 20 and two clamping blocks 21. The clamping drive member 20 adopts a clamping drive cylinder. The clamping drive cylinder has two piston rod ends arranged in the left and right directions, and each piston rod end is connected to a clamping block 21. The clamping drive cylinder is used to drive the two clamping blocks 21 to move toward each other to a set position to clamp the terminal box 22. The clamping block 21 has two clamping heads 2101 arranged at intervals in the front-to-back direction, and the spacing between the two clamping heads 2101 is greater than the width of the clamping end of the above-mentioned grabbing clamp 9, so that when the grabbing assembly moves to the junction box 22 on the junction box feeding mechanism, the grabbing clamp 9 can be clamped on the outer wall of the junction box 22 located between the two clamping heads 2101, so that the clamping block 21 can clamp the junction box 22 to keep the junction box 22 in a fixed state while the grabbing clamp 9 grabs the junction box 22, so as to avoid the junction box 22 shaking when the grabbing clamp 9 grabs the junction box 22, resulting in inaccurate clamping position.

[0090] Among the three groups of junction box feeding mechanisms mentioned above, the two groups of junction box feeding mechanisms located on both sides are used to place wired junction boxes, and the group of junction box feeding mechanisms located in the middle is used to place wireless junction boxes.

[0091] The solar panel conveying unit includes a solar panel conveying line 60, which is located below the above-mentioned straightening assembly. The solar panel conveying line 60 is used to convey the solar panels in the front-to-back direction, so that the solar panels are moved to a state where the wiring on the solar panels are respectively located below the above-mentioned three groups of straightening assemblies.

[0092] The junction box installation device is provided with a control module, which is used to respond to the detection results of each detection element in the device to control each power element in the device to act. The control process is a prior art and will not be described in detail here.

[0093] When the utility model is in use, the first material box 35 filled with wired junction boxes is first placed on the feeding conveyor line 33, and the feeding conveyor line 33 drives the first material box 35 to be conveyed forward. After the first material box 35 moves to the reciprocating conveyor line 38, the reciprocating conveyor line 38 stops conveying forward, and the first transfer component 37 grabs the wired junction boxes in the first material box 35. When the wired junction boxes in the first material box 35 are taken out, the feeding lifting cylinder drives the reciprocating conveyor line 38 and the first material box 35 on the reciprocating conveyor line 38 to move downward to the reflux conveyor line 34, and the empty first material box 35 moves to the reflux conveyor line 34 and is output along the reflux conveyor line 34.

[0094] The first transfer assembly 37 transfers the captured wired junction box to the weighing platform 39. When the weight sensor 40 below the weighing platform 39 detects that the weight of the wired junction box exceeds the set range, the rotating drive member drives the weighing platform 39 to rotate to an inclined state, so that the wired junction box on the weighing platform 39 falls into the second material box 42 along the drop channel 41. When the weight sensor 40 detects that the weight of the wired junction box is within the set range, the second transfer assembly transfers the wired junction box to the feeding platform 44. The flipping and transferring mechanism grabs the wired junction box on the feeding platform 44 and transfers the wired junction box to the bottom of the front and back visual inspection camera 61. If the front and back visual inspection camera 61 detects that the back of the wired junction box is facing upward, the flipping and transferring mechanism flips the wired junction box and then transfers the wired junction box to the storage conveyor line 57. If the front and back visual inspection camera 61 detects that the front of the wired junction box is facing upward, the flipping and transferring mechanism directly transfers the wired junction box to the storage conveyor line 57. The stock conveyor line 57 is intermittently conveyed forward. When the in-place visual inspection camera 59 detects the wired junction box on the material-collecting position of the stock conveyor line 57, the third transfer component 58 grabs the wired junction box and transfers it to the corresponding junction box loading mechanism. While the wired junction box is being loaded, the wireless junction box is also being loaded. The wireless junction boxes are sequentially transported from the inside of the vibration feeder to the outlet of the vibration feeder and moved to the wireless junction box pallet 45. The fourth transfer component transfers the wireless junction box on the wireless junction box pallet 45 to the wireless junction box conveyor line 48. The third transfer component 58 transfers the wireless junction box transported to the end of the wireless junction box conveyor line 48 to the junction box loading mechanism located in the middle.

[0095] The transverse driving mechanism drives the transverse beam 25 to move on the frame 24 in the left and right directions, thereby driving the mobile frame 1 to move on the frame 24 in the left and right directions. The mobile frame 1 drives the grabbing assembly and the bending and pressing assembly thereon to move above the wiring box feeding mechanism. At this time, the grabbing driving component 8 drives the two grabbing clamps 9 to approach each other, so that the two grabbing clamps 9 are clamped on the outer wall of the wiring box 22 clamped by the clamping assembly on the feeding platform 17, and the grabbing clamps 9 are located between the two clamping heads 2101. After the two grabbing clamps 9 clamp the wiring box 22, the clamping assembly releases the wiring box 22, and the grabbing assembly grabs the wiring box 22 and transfers the grabbed wiring box 22 to above the wiring of the solar panel fixed on the frame 24 as the mobile frame 1 moves. At this time, the second lifting drive mechanism 30 drives the support seat 28 to move downward, driving the straightening assembly to move to a height position corresponding to the wiring of the solar panel, and the second telescopic drive member 15 drives the movable plate 32 to move toward the wiring of the solar panel, so that the middle plug plate 12 is inserted between the two wirings on the solar panel, and the side straightening plate 11 extends to the side of the two wirings. Then, the straightening drive member 13 drives the two side straightening plates 11 to move toward the middle plug plate 12, so that the two side straightening plates 11 and the middle plug plate 12 clamp the two wirings to straighten the wiring.

[0096] After the wiring is straightened, the first lifting drive mechanism 2 drives the entire mounting bracket 3 to move downward, driving the terminal box 22 grabbed by the grabbing assembly to move downward from top to bottom, so that the wiring passes through the socket 2201 on the terminal box 22. After a part of the wiring passes through the socket 2201, the straightening drive member 13 drives the two side straightening plates 11 to move away from the middle plug plate 12 to release the wiring, and then the second telescopic drive member 15 drives the middle plug plate 12 and the side straightening plates 11 to withdraw from the wiring, and the first lifting drive mechanism 2 continues to drive the grabbing assembly to move downward so that the wiring completely passes through the socket 2201 on the terminal box 22. After that, the lifting drive member 4 drives the mounting plate 5 to drive the roller 10 and the pressing block 6 thereon to move downward, and the roller 10 pushes the two push surfaces 701, so that the two bending push plates 7 move away from each other, and the bending push plates 7 push the two wirings to bend to both sides, and at the same time, the pressing block 6 moves downward to the bent wiring to flatten the bent wiring. The end of the wire is pressed and folded onto the metal welding block 2202 on the junction box 22. At this time, the wire is welded to the metal welding block 2202 using welding equipment to complete the assembly of the junction box 22.

[0097] The utility model can realize the automatic assembly of the junction box, the assembly efficiency is higher, and the labor cost can be effectively reduced.

[0098] In this embodiment, the feeding component includes a feeding conveyor line and a reflux conveyor line. The feeding lifting cylinder and the reciprocating conveyor line are arranged to cooperate with the feeding conveyor line and the reflux conveyor line to realize the loading of the first material box and the recovery of the empty first material box. In other embodiments, the feeding component includes a material box conveyor line extending in the front-to-back direction. A plurality of first material boxes arranged at equal intervals are placed on the material box conveyor line. The material box conveyor line conveys forward intermittently. The material box conveyor line drives each first material box to move to the bottom of the first transfer component in turn and stay for a set time. After the first transfer component takes out the wired junction box in the first material box, the material box conveyor line drives the empty first material box to continue to convey forward, so that the empty first material box leaves the bottom of the first transfer component.

[0099] In this embodiment, the weighing platform is rotatably mounted on the frame, and the rejection mechanism includes a rotating drive member, which is used to drive the weighing platform to flip so as to reject the wired junction box with a weight exceeding the range. In other embodiments, the weighing platform is fixed on the frame, and the rejection mechanism includes a push-rejection cylinder, and the piston rod end of the push-rejection cylinder is connected to a push-rejection plate, and the push-rejection cylinder is used to drive the push-rejection plate to move so as to reject the wired junction box with a weight exceeding the range on the weighing platform to the bottom of the weighing platform.
