Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module assembly equipment, and in particular to a photovoltaic module corner protector disassembly device. Background Art

[0002] The patent document with publication number CN117059707A discloses an automatic corner guard removal device. Paragraph 0039 of the patent specification states that "a bearing is installed in the base plate, and a rotating shaft arranged at the bottom of the carrier plate is inserted into the bearing to form a rotating structure"; Paragraph 0048 of the specification states that "when the correction baffle contacts the corner guard, it will receive a thrust from the corner guard, so that the entire removal module will adaptively rotate until the two fixed arms of the corner guard fit with the corresponding correction baffle", but the center of the rotating shaft is close to the force point of the corner guard, and the force arm is short, so a large force is required to push the corner guard clamping assembly including the correction baffle to rotate. If the two fixed arms of the corner guard cannot fit correctly with the correction baffle, it is very likely that the photovoltaic module will be damaged in the process of pulling the corner guard backwards. Summary of the invention

[0003] Therefore, an object of the present invention is to provide a photovoltaic module corner protection device, which at least partially solves the problems in the prior art.

[0004] A photovoltaic module corner protection removal device provided in the present application includes a working unit, a follower unit and a driving unit arranged in sequence from top to bottom; The working unit comprises a clamping assembly and a cutting unit, wherein the clamping assembly is used to clamp the corner protector located at the corner of the photovoltaic module, and the cutting unit is used to cut the C-shaped tape of the corner protector; The driving unit comprises a first driving member for driving the working unit to move toward or away from the corner guard along a first linear motion direction, and a second driving member for driving the working unit to rotate; The follower unit includes a first connection part connected to the driving unit, and a second connection part connected to the working unit; two first linear guide rails parallel to the first movement direction are arranged on the top of the first connection part, and a second linear guide rail is arranged on the bottom of the second connection part; a first connection member is slidably arranged on the first linear guide rail, and a second connection member is slidably arranged on the second linear guide rail; the first connection member and the second connection member are connected by a rotating shaft, so that two rotation fulcrums are formed between the first connection member and the second connection member; The follower unit includes a reset member, and in the process that the first driving member drives the working unit to move away from the corner protector, the reset member drives the second connecting part to gradually reset to an initial state.

[0005] Preferably, in an initial state, the first linear guide rail is perpendicular to the second linear guide rail.

[0006] According to some embodiments, a thrust ball bearing is provided in the first connecting member, one end of the rotating shaft is fixedly connected to the second connecting member, and the other end is fixedly connected to the inner ring of the thrust ball bearing.

[0007] How this application works is: When the first driving member drives the clamping assembly to move linearly toward the corner guard, the corner guard contacts the clamping assembly, and the clamping assembly is pushed by the corner guard. The second connection part can make random compound motion relative to the first connection part. The compound motion includes linear motion of the second connection part relative to the first connection part along the first motion direction, linear motion of the second connection part relative to the first connection part along the second motion direction, and rotational motion of the second connection part relative to the first connection part around the central axis of the rotating shaft, and the second motion direction is perpendicular to the first motion direction. The above three motion modes are randomly generated according to the position angle relationship between the corner guard and the clamping assembly until the clamping assembly is adjusted to the accurate clamping position.

[0008] With the corner guard removal device disclosed in the present invention, the first connection part and the second connection part are movably connected through two sets of slide rail slider assemblies. At the moment when the corner guard pushes the second connection part to move along the first movement direction or the second movement direction, the second connection part rotates. There are two rotation fulcrums between the first connection part and the second connection part. The two rotation fulcrums are relatively far away from the contact point between the corner guard and the clamping assembly, and the force arm is long. Only a small thrust is needed to push the second connection part to rotate. The relative position of the two rotation fulcrums can be adjusted in real time, with a wide adjustment angle, and the position of the clamping assembly can be accurately adjusted. The two fixed arms of the corner guard can be properly fitted with the return baffle of the clamping assembly.

[0009] According to some embodiments, the reset member is a spring, and in the process of the first driving member driving the working unit away from the corner guard, the spring drives the first connecting member to reset along the first linear guide rail, and the spring drives the second connecting member to reset along the second linear guide rail. Preferably, the first connecting member is provided with a first guide rod parallel to the first linear guide rail, the first guide rod is provided with the spring, the first connecting portion is provided with a first guide block, and the end of the first guide rod is inserted into the guide hole of the first guide block. Preferably, the bottom of the second connecting portion is provided with a fixed block located between the two second connecting members, the fixed block is provided with a second guide rod parallel to the second linear guide rail, the second guide rod is provided with the spring; the second connecting member is provided with a second guide block, and the end of the second guide rod is inserted into the guide hole of the second guide block.

[0010] By arranging springs for the first connection part and the second connection part, automatic reset of the first connection part and the second connection part can be achieved, and the second connection part cannot swing arbitrarily under the restriction of the spring force.

[0011] According to some embodiments, the follower unit includes a limiting mechanism; the limiting mechanism includes a limiting groove provided in the second connection part, and a roller connected to the first connection part is inserted into the limiting groove. The position of the roller provided on the first connection part remains stationary, and the second connection part moves relative to the first connection part. When the inner groove edge of the limiting groove contacts the roller, the second connection part cannot continue to deflect, and the follow-up deflection angle of the second connection part is limited. Preferably, a cylinder is provided on the first connection part, and a locking groove connected to the limiting groove is provided in the second connection part. When the clamping assembly does not contact the corner guard, or during the translation or rotation of the working unit, the cylinder drives the roller to enter the locking groove to lock the second connection part, so as to prevent the working unit from shaking.

[0012] According to some embodiments, the clamping assembly includes a clamping claw cylinder fixed to the second connection part, and an upper clamping plate and a lower clamping plate respectively connected to two fingers of the clamping claw cylinder, and the lower clamping plate is provided with two upwardly extending return baffles, and after the edge of the corner guard is in contact with the return baffles, the clamping claw cylinder drives the upper clamping plate and the lower clamping plate to clamp the corner guard. The clamping assembly is fixedly connected to the second connection part, and after the clamping assembly receives the thrust from the corner guard, the second connection part retreats along the first movement direction together with the clamping assembly and the cutter unit arranged above it, and the clamping assembly and other mechanisms on the second connection part are relatively maintained unchanged, which is convenient for debugging and stable operation of the equipment.

However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0016] Unless the context requires otherwise, throughout the specification and claims, the word "comprise" and variations such as "include" and "have" should be construed as having an open, inclusive meaning, ie, should be interpreted as meaning "including, but not limited to."

[0017] Example like Figure 1 and 2 As shown, the glue overflowing from the photovoltaic component A forms a glue bead C between the corner protector B and the photovoltaic component A, which causes the corner protector B to be skewed relative to the photovoltaic component A.

[0018] The corner protection removal equipment is generally provided with four corner protection removal devices, which correspond to the four corners of the photovoltaic module respectively. The photovoltaic module is positioned correctly in the equipment, and the corner protection removal devices are moved close to the corners of the photovoltaic module.

[0019] Figure 4 The photovoltaic module corner protection removal device shown in the figure includes a working unit 100, a follower unit 200 and a driving unit 300 which are arranged in sequence from top to bottom.

[0020] The working unit 100 includes a clamping assembly 110 and a cutting unit 120. The clamping assembly is used to clamp the corner guard at the corner of the photovoltaic module, and the cutting unit is used to cut the C-shaped tape of the corner guard. Figure 3The clamping assembly 110 includes a clamping claw cylinder 111, and an upper clamping plate 112 and a lower clamping plate respectively connected to two fingers of the clamping claw cylinder. The lower clamping plate is provided with two upwardly extending return baffles 113. After the edge of the corner guard is in contact with the return baffles, the clamping claw cylinder drives the upper clamping plate and the lower clamping plate to clamp the corner guard. The cutting unit 120 includes two sets of cutting mechanisms respectively arranged on both sides of the clamping unit; the cutting mechanism includes a cutting cylinder 121 and a cutting assembly 122. The cylinder drives the cutting assembly to move along the edge of the corner guard to cut the C-type tape.

[0021] The driving unit 300 includes a first driving member 310 for driving the working unit 100 to move toward or away from the corner guard along a first linear motion direction, and a second driving member 320 for driving the working unit 100 to rotate. Figure 4 The base platform 400 of the corner guard removal device is provided with a third linear guide rail 500, the mounting plate of the second driving member 320 is slidably connected to the third linear guide rail, the first driving member is preferably a cylinder, the cylinder body of which is fixed on the base platform 400, and the telescopic rod is fixedly connected to the mounting plate. The second driving member is preferably a rotary cylinder, and the follower unit is fixed on the rotary table of the rotary cylinder.

[0022] like Figure 5-7 As shown, the follower unit includes a first connection part 210 connected to the second driving member, and a second connection part 220 connected to the working unit. The clamping assembly 110 and the cutter unit 120 are fixed on the second connection part. Two first linear guides 230 parallel to the first movement direction D are arranged on the top of the first connection part, and a second linear guide 240 is arranged on the bottom of the second connection part 220. A first connecting member 250 is slidably arranged on the first linear guide, and a second connecting member 260 is slidably arranged on the second linear guide. The first connecting member and the second connecting member are connected by a rotating shaft so that two rotation fulcrums are formed between the first connecting member 210 and the second connecting member 220. Preferably, a thrust ball bearing 280 is arranged in the first connecting member 250, one end of the rotating shaft is fixedly connected to the second connecting member 260, and the other end is fixedly connected to the inner ring of the thrust ball bearing 280.

[0023] In the initial state of the follower unit, the direction of the first linear guide is parallel to the first movement direction D, and the first linear guide 230 is perpendicular to the second linear guide 240. If the position of the corner guard B is accurate and not skewed relative to the photovoltaic component 2, the second connecting portion 220 will not deflect. If the corner guard B is skewed relative to the photovoltaic component A (such as Figure 2As shown in the figure, one corner edge of the corner guard first contacts the corresponding return baffle 113, and the clamping assembly 110 is subjected to the oblique thrust from the corner guard. The two connecting members at the bottom of the second connecting portion 220 rotate in the same direction, and the second connecting portion will deflect relative to the first connecting portion 210. Due to the sliding connection between the second connecting portion and the second connecting member 260, the second connecting portion will translate relative to the second connecting portion, and the clamping assembly is quickly corrected by the corner guard. After the clamping assembly 110 is corrected, the two corner edges of the corner guard B are both in contact with the return baffle 113, the second connecting portion 220 stops deflecting, and the clamping plate of the clamping assembly clamps the corner guard.

[0024] like Figure 7 As shown, after the second connection part 220 is deflected relative to the first connection part 210, the second connection part cannot automatically reset, so in this embodiment, a reset member is set in the follower unit 200. When the first driving member 310 drives the working unit 100 away from the corner guard, the reset member drives the first connection part to gradually reset to the initial state.

[0025] The reset member is a spring. When the first driving member 310 drives the working unit 100 away from the corner guard, the thrust applied by the corner guard gradually disappears, the first spring 252 drives the first connecting member to reset along the first linear guide rail 230, and the second spring 263 drives the second connecting member to reset along the second linear guide rail 240. During the translation of the first connecting member and the second connecting member, the second connecting member rotates around the fulcrum to align the second connecting part 220. After the two corner edges of the corner guard B are both in contact with the alignment baffle 113, the spring force of the spring can also prevent the second connecting part from continuing to deflect due to the vibration of the machine.

[0026] In some embodiments, a first guide rod 251 parallel to the first linear guide rail 230 is provided on the first connector 250, a first spring 252 is provided on the first guide rod, a first guide block 253 is provided on the first connector 210, and the end of the first guide rod is inserted into the guide hole of the first guide block. When the first connector 250 moves backward along the first linear guide rail 230, the first spring 252 is compressed, and when the applied thrust gradually disappears, the first spring rebounds and drives the first connector to move toward the photovoltaic module.

[0027] In some embodiments, a fixing block 261 located between two second connecting members 260 is provided at the bottom of the second connecting portion 220, a second guide rod 262 parallel to the second linear guide rail 240 is provided on the fixing block, and a second spring 263 is provided on the second guide rod. A second guide block 264 is provided on the second connecting member, and the end of the second guide rod is inserted into the guide hole of the second guide block. When the second connecting portion 220 moves along the first linear guide rail 230, the second spring 263 on one side is compressed, and the second spring on the other side is stretched. When the applied thrust gradually disappears, the second spring rebounds and resets to drive the second connecting portion 220 to be straightened.

[0028] like Figure 7 As shown, the first connecting member 250 in the follower unit 200 moves to the end of the first linear guide rail 230 corresponding to the photovoltaic assembly, which is the maximum deflection angle of the clamping assembly 110 and the second connecting portion 220. In actual production applications, the corner guard will not produce such a large angle of deflection, so in some embodiments, the follower unit 200 is provided with a limit mechanism 290 for limiting the deflection angle of the clamping assembly 110. Figure 6 As shown, the limiting mechanism includes a limiting groove 291 arranged in the second connecting part, and two rollers 292 connected to the first connecting part 210 are inserted into the limiting groove. The positions of the rollers remain stationary, and the second connecting part 220 deflects relative to the first connecting part 210. When the inner groove edge of the limiting groove contacts the rollers, the second connecting part can no longer deflect, and the follow-up deflection angle is limited.

[0029] In some embodiments, a cylinder 293 is provided on the first connecting part 210, and a locking groove 294 connected to the limiting groove 291 is provided in the second connecting part 220. When the clamping assembly 110 does not contact the corner guard, or during the translation or rotation of the working unit 100, the cylinder drives the roller 292 to enter the locking groove to lock the second connecting part 220, thereby preventing the working unit from shaking.

[0030] In summary, the photovoltaic component corner guard disassembly device provided in this embodiment has the advantages of a wider position adjustment angle of the clamping component, smaller thrust required, and higher position accuracy relative to the corner guard, compared with the existing disassembly device.
