Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell technology, and in particular to a device for bending leads of high-temperature solar panel fabric. Background Technology

[0002] Solar photovoltaic (PV) modules are generally assembled from large photovoltaic panels and four frames. The photovoltaic panels convert light energy into electrical energy through a photoelectric conversion device, and then the electrical energy is conducted out through leads. Sometimes, high-temperature cloth is needed to insulate the connection points between the leads and the photovoltaic panels.

[0003] Chinese patent CN214161210U discloses a high-temperature cloth bending machine for photovoltaic modules. This equipment uses a transfer robotic arm to remove high-temperature cloth from the high-temperature cloth feeding device, move it to the lead wire location, allow the lead wire to pass through the middle of the high-temperature cloth, and then bend the two lead wires to both sides, thereby confining the high-temperature cloth. The problem is that the high-temperature cloth is a small, soft piece of material, which is generally stacked in the high-temperature cloth feeding device. There is a possibility of stacking during removal, making it impossible to guarantee that each piece is placed at the lead wire location. This could cause the high-temperature cloth to fall onto the photovoltaic module, resulting in material waste and cleaning difficulties. Furthermore, the equipment has a fixed overall size and a monolithic structure, making installation inflexible.

[0004] Therefore, it is necessary to improve the equipment to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide a device for bending and connecting high-temperature cloth to a solar panel. This device breaks down the placement of the high-temperature cloth into four actions, with each action completed by a single mechanism. This reduces component costs and increases the overall work speed. The device also features a modular structure and flexible installation.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a solar panel high-temperature cloth bending lead device, comprising a feeding unit, a feeding robot, a plate feeding unit, and a vision unit. The feeding unit and the feeding robot are disposed on the same side of the plate feeding unit in the Y direction, and the vision unit is disposed above the plate feeding unit. The feeding unit includes a frame, a camera assembly disposed on the upper part of the frame, a flexible vibrating plate located directly below the camera assembly, a feeding robot located between the flexible vibrating plate and the plate feeding unit, a feeding mechanism located on the side of the flexible vibrating plate away from the plate feeding unit, and a transfer platform located on the X-direction side of the flexible vibrating plate. The X and Y directions are both located in the horizontal plane and are perpendicular to each other.

[0007] Specifically, the plate feeding unit includes a plate feeding timing belt, an X-direction alignment mechanism arranged in pairs on both sides of the plate feeding timing belt in the X direction, and a Y-direction alignment mechanism arranged in pairs on both sides of the plate feeding timing belt in the Y direction.

[0008] Furthermore, the vision unit includes a vision bracket spanning above the feeding synchronous belt and multiple vision modules arranged side by side on the vision bracket along the Y direction, wherein the vision modules take pictures of the upper surface of the photovoltaic panel at an angle downward.

[0009] Furthermore, the vision support is provided with a Y-direction extending track frame, and the vision module is movably fixed on the track frame.

[0010] Specifically, the loading robot includes a loading robot arm and a loading gripper located at the free end of the loading robot arm. The loading gripper includes a gripper mounting plate connected to the end of the loading robot arm, a plurality of loading slide cylinders arranged side by side below the gripper mounting plate, and a loading suction nozzle that is independently driven to rise and fall by each loading slide cylinder.

[0011] Specifically, the feeding mechanism includes a mounting base connected to the frame, a feeding hopper rotatably connected to the mounting base along the X-axis, a ratchet on the rotating shaft of the feeding hopper, and a pen-shaped cylinder that drives the ratchet to rotate.

[0012] Specifically, the transfer platform has several transfer positions arranged side by side along its length. The unloading robot includes a unloading robot arm and a unloading gripper located at the free end of the unloading robot arm. The unloading gripper includes a suction cup assembly and a gripper assembly. The suction cup assembly includes a flange connecting frame connected to the unloading robot arm, multiple unloading slide cylinders arranged side by side at the front of the flange connecting frame, and a pair of unloading suction nozzles driven independently by each unloading slide cylinder. The gripper assembly includes a horizontal slide cylinder connected to the lower part of the flange connecting frame, a cylinder connecting plate driven by the horizontal slide cylinder to move closer to and away from the unloading suction nozzle, multiple gripper cylinders arranged side by side on the cylinder connecting plate, and a pair of grippers driven by each gripper cylinder to move closer to and away from the unloading suction nozzle. The number of gripper cylinders, the number of unloading slide cylinders, and the number of transfer positions on the transfer platform are equal. When the unloading suction nozzle descends, each pair of grippers is located between a pair of unloading suction nozzles.

[0013] The beneficial effects of this utility model's technical solution are:

[0014] 1. The placement of the high-temperature fabric is broken down into four actions. The first action is to pour the high-temperature fabric from the feeding hopper into the flexible vibrating plate. The position of the high-temperature fabric in the feeding hopper is not critical, making control simple and allowing for a large feeding capacity. The second action is for the flexible vibrating plate to disperse the high-temperature fabric, solving the problem of overlapping. The third action is for the feeding robot to orderly place the scattered high-temperature fabric onto the transfer platform, solving the problem of positioning the high-temperature fabric. The fourth action is for the unloading robot to remove the high-temperature fabric from the transfer platform and then attach it one by one to the lead wire. The same action is completed by a single mechanism, saving on parts costs and ensuring a fast overall work pace.

[0015] 2. Modular components facilitate on-site installation and allow for flexible layout. Attached Figure Description

[0031] The present invention will be further described in detail below with reference to specific embodiments.

[0032] Example:

[0033] like Figure 1 As shown, the present invention provides a robotic high-temperature cloth-making device 100, which includes a feeding unit 1, a feeding robot 2, a plate-feeding unit 3 and a vision unit 4. The feeding unit 1 and the feeding robot 2 are located on the same side of the plate-feeding unit 3 in the Y direction, and the vision unit 4 is located above the plate-feeding unit 3.

[0034] In this equipment, the feeding unit 1, the unloading robot 2, the plate feeding unit 3, and the vision unit 4 are all modular, making on-site installation convenient and the layout flexible.

[0035] like Figure 2 As shown, the feeding unit 3 includes a feeding timing belt 31, an X-direction alignment mechanism 32 arranged in pairs on both sides of the feeding timing belt 31 in the X direction, and a Y-direction alignment mechanism 33 arranged in pairs on both sides of the feeding timing belt 31 in the Y direction. The X and Y directions are both located in the horizontal plane and are perpendicular to each other.

[0036] The feeding timing belt 31 is used to transport the photovoltaic panel 200 along the X direction. When the photovoltaic panel 200 reaches the middle of the feeding timing belt 31, the two X-direction alignment mechanisms 32 can be raised to align the photovoltaic panel 200 in the front-back direction, and the two Y-direction alignment mechanisms 33 can align the photovoltaic panel 200 in the left-right direction, so that the photovoltaic panel 200 is within the feeding range of the unloading robot 2.

[0037] like Figure 1 As shown, the vision unit 4 includes a vision bracket 41 spanning above the feeding synchronous belt 31 and multiple vision modules 42 arranged side by side on the vision bracket 41 along the Y direction. The vision modules 42 shoot the upper surface of the photovoltaic panel 200 at an angle downward. The vision bracket 41 is provided with a track frame 43 extending in the Y direction, and the vision modules 42 are movably fixed on the track frame 43.

[0038] Because the material handling robot 2 needs to place the high-temperature cloth 300 onto the photovoltaic panel 200 from top to bottom, and the high-temperature cloth 300 needs to be passed through by the lead wire 201, the vision module 42 needs to detect the position of the lead wire 201 from an oblique angle. Therefore, the vision module 42 needs to take a downward-angled image of the upper surface of the photovoltaic panel 200. The lead wire 201 is arranged in an island shape on the photovoltaic panel 200 and is arranged side by side along the Y direction. The position of the lead wire 201 will vary depending on the size of the photovoltaic panel 200. The vision module 42 needs to be able to fine-tune its Y-direction position along the track frame 43 to ensure that the lead wire 201 it detects falls within its field of view.

[0039] like Figure 3 and Figure 4 As shown, the feeding unit 1 includes a frame 11, a camera assembly 12 located on the upper part of the frame 11, a flexible vibrating plate 13 located directly below the camera assembly 12, a feeding robot 14 located between the flexible vibrating plate 13 and the feeding unit 3, a feeding mechanism 15 located on the side of the flexible vibrating plate 13 away from the feeding unit 3, and a transfer platform 16 located on the X-direction side of the flexible vibrating plate 13. The feeding robot 14 includes a feeding robot arm 141 and a feeding gripper 142 located at the free end of the feeding robot arm 141. The feeding gripper 142 includes a gripper mounting plate 1421 connected to the end of the feeding robot arm 141, a plurality of feeding slide cylinders 1422 arranged side by side below the gripper mounting plate 1421, and a feeding suction nozzle 1423 that is independently driven to rise and fall by each feeding slide cylinder 1422. A plurality of transfer positions are arranged side by side along the length direction on the transfer platform 16.

[0040] The high-temperature cloth 300 used on the photovoltaic panel 200 is a sheet material with a size of about 1 cm. The feeding mechanism 15 is used to feed the high-temperature cloth 300 in batches to the flexible vibrating plate 13. When the high-temperature cloth 300 first lands on the flexible vibrating plate 13, it will stack up, but under the vibration of the flexible vibrating plate 13, the high-temperature cloth 300 will collapse and separate, and adjacent high-temperature cloth 300 will not be completely stuck together. This allows the feeding gripper 142 to pick up the high-temperature cloth 300 one by one, preventing stacking. Each feeding nozzle 1423 can independently pick up one piece of high-temperature cloth 300, so the feeding gripper 142 only needs to move slightly within the range of the flexible vibrating plate 13 to quickly pick up multiple pieces of high-temperature cloth 300, and then move them together to the transfer platform 16 for placement. The camera assembly 12 is used to identify the actual position of the scattered high-temperature cloth 300 and guide the feeding nozzle 1423 to pick up the high-temperature cloth 300.

[0041] like Figure 5 As shown, the feeding mechanism 15 includes a mounting base 151 connected to the frame 11, a feeding hopper 152 rotatably connected to the mounting base 151 along the X-axis, a ratchet 153 disposed on the rotating shaft of the feeding hopper 152, and a pen-shaped cylinder 154 that pushes the ratchet 153 to rotate.

[0042] The feeding hopper 152 has a scoop-shaped structure. The part away from the rotating shaft has an upward opening, and the part near the rotating shaft forms a feeding channel. When the opening is lower than the rotating shaft, it can be used to put loose high-temperature cloth 300. When the opening is higher than the rotating shaft, the feeding channel can tilt the high-temperature cloth 300 onto the flexible vibrating plate 13. The oscillation of the feeding hopper 152 is accomplished by the ratchet 153 driven by the pen-shaped cylinder 154.

[0043] like Figure 6 and Figure 7As shown, the unloading robot 2 includes an unloading robot arm 21 and an unloading gripper 22 located at the free end of the unloading robot arm 21. The unloading gripper 22 includes a suction cup assembly 221 and a gripper assembly 222. The suction cup assembly 221 includes a flange connecting frame 2211 connected to the unloading robot arm 21, multiple unloading slide cylinders 2212 arranged side by side at the front of the flange connecting frame 2211, and a pair of unloading suction nozzles 2213 independently driven by each unloading slide cylinder 2212. The gripper assembly 222 includes a horizontal slide cylinder connected to the lower part of the flange connecting frame 2211. The system comprises a cylinder 2221, a cylinder connecting plate 2222 driven by a horizontal slide cylinder 2221 to move closer to and away from the feeding nozzle 2213, multiple gripper cylinders 2223 arranged side-by-side on the cylinder connecting plate 2222, and a pair of grippers 2224 driven by each gripper cylinder 2223 to move closer to and away from the feeding nozzle 2213. The number of gripper cylinders 2223, the number of feeding slide cylinders 2212, and the number of transfer positions on the transfer platform 16 are equal. When the feeding nozzle 2213 descends, each pair of grippers 2224 is positioned between a pair of feeding nozzles 2213. The camera assembly 12 helps the loading robot 14 and the feeding manipulator 2 to position themselves so that the high-temperature cloth 300 can be picked up in the required posture and placed in the correct position.

[0044] The feeding nozzle 2213 is used to pick up the pre-positioned high-temperature cloth 300 from the transfer position. The grippers 2224 are positioned alternately with the feeding nozzle 2213. When the suction cup assembly 221 places the high-temperature cloth 300 onto the photovoltaic panel 200, a pair of leads 201 pass vertically through the high-temperature cloth 300 and are located outside the two grippers 2224. The grippers 2224 are used to flip the two leads 201 outwards to both sides, thus fixing the high-temperature cloth 300 onto the photovoltaic panel 200. Pressing down on the leads 201 simultaneously fixes the position of the high-temperature cloth 300, improving work efficiency, reducing cycle time, and making it more flexible to use.

[0045] The working process of the solar panel high-temperature cloth bending lead wire equipment 100 is as follows:

[0046] High-temperature fabric 300 is fed in batches from hopper 152 to flexible vibratory feeder 13, which vibrates to disperse the high-temperature fabric 300. After the vibration stops, camera assembly 12 identifies the position of the high-temperature fabric 300, and loading robotic arm 141 moves loading gripper 142 above flexible vibratory feeder 13. Multiple loading slide cylinders 1422 in loading gripper 142 sequentially drive loading nozzles 1423 downward to pick up the high-temperature fabric 300. Then, loading robotic arm 141 moves loading gripper 142 above transfer platform 16 and places high-temperature fabric 300 one by one on the transfer position on transfer platform 16. After loading gripper 142 leaves the transfer platform 16, unloading gripper 22 moves to transfer platform 16. Multiple sets of feeding slide cylinders 2212 simultaneously drive the feeding suction nozzle 2213 to descend, thereby picking up all the high-temperature cloth 300 on the transfer platform 16. Under the monitoring of the vision module 42, the feeding gripper 22 moves the high-temperature cloth 300 one by one to the position of the lead wire 201 on the photovoltaic panel 200, so that the high-temperature cloth 300 is passed through the lead wire 201. The feeding suction nozzle 2213 releases the high-temperature cloth 300 and retracts to the top. Then the gripper 2224 presses the lead wire 201 from the middle to both sides to fix the high-temperature cloth 300. After fixing all the high-temperature cloth 300 in a batch, the feeding robot 2 goes to the transfer platform 16 to pick up another batch of high-temperature cloth 300. This process is repeated to complete the operation of feeding the high-temperature cloth 300 and bending the lead wire 201.

[0047] The placement of the high-temperature cloth 300 is divided into four actions. The first action is to pour the high-temperature cloth 300 from the feeding hopper 152 into the flexible vibrating plate 13. The position of the high-temperature cloth 300 in the feeding hopper 152 is not required, making control simple and allowing for a large feeding volume. The second action is for the flexible vibrating plate 13 to disperse the high-temperature cloth 300, solving the problem of stacking. The third action is for the feeding robot 14 to place the scattered high-temperature cloth 300 in an orderly manner onto the transfer platform 16, solving the positioning problem of the high-temperature cloth 300. The fourth action is for the unloading robot 2 to remove the high-temperature cloth 300 from the transfer platform 16 together and then attach them one by one to the guide wire 201. The same action is completed by a set of mechanisms, saving parts costs and increasing the overall work pace.

[0048] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
