Description

Technical Field

[0001] This application relates to the technical field of photovoltaic module assembly equipment, and particularly to a device for disassembling corner protectors of photovoltaic modules. Background Art

[0002] A patent document with the publication number CN117059707A discloses an automatic corner protector disassembly device. Paragraph 0039 of the specification of the above patent records that "bearings are installed in the substrate, and the rotating shafts provided at the bottom of the carrier plate are inserted into the bearings to form a rotating structure"; paragraph 0048 of the specification records that "when the alignment flap contacts the corner protector, it will receive a thrust from the corner protector, so that the entire disassembly module will adaptively rotate until the two fixing arms of the corner protector are in contact with the corresponding alignment flaps". However, the center of the rotating shaft is relatively close to the force application point of the corner protector, and the force arm is short. A relatively large force is required to push the corner protector clamping assembly including the alignment flap to rotate. If the two fixing arms of the corner protector cannot be correctly attached to the alignment flap, it is very likely to damage the photovoltaic module during the process of pulling the corner protector backward. Summary of the Invention

[0003] Therefore, the purpose of the present invention is to provide a device for disassembling corner protectors of photovoltaic modules, which at least partially solves the problems in the prior art.

[0004] A device for disassembling corner protectors of photovoltaic modules provided according to the present application includes a working unit, a follower unit, and a driving unit arranged in sequence from top to bottom;

[0005] The working unit includes a clamping assembly and a cutter unit. The clamping assembly is used to clamp the corner protector located at the corner of the photovoltaic module, and the cutter unit is used to cut the C-shaped tape of the corner protector;

[0006] The driving unit includes a first driving member for driving the working unit to move linearly in a first movement direction close to or away from the corner protector, and a second driving member for driving the working unit to rotate;

[0007] 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 provided at the top of the first connection part, a second linear guide rail is provided at the bottom of the second connection part, a first connecting member is slidably arranged on the first linear guide rail, a second connecting member is slidably arranged on the second linear guide rail, and the first connecting member and the second connecting member are connected by a rotating shaft, so as to form two rotation fulcrums between the first connection part and the second connection part;

[0008] The follower unit includes a reset member. During the process of the first driving member driving the working unit away from the corner protector, the reset member drives the second connection part to gradually reset to the initial state.

[0009] Preferably, in the initial state, the first linear guide rail is perpendicular to the second linear guide rail.

[0010] 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.

[0011] The working principle of the present application is as follows:

[0012] During the process that the first driving member drives the clamping assembly to linearly move towards the corner guard, the corner guard contacts the clamping assembly. The clamping assembly receives the thrust of the corner guard, and the second connecting portion can perform a random composite movement relative to the first connecting portion. The composite movement includes the linear movement of the second connecting portion relative to the first connecting portion along the first movement direction, the linear movement of the second connecting portion relative to the first connecting portion along the second movement direction, and the rotational movement of the second connecting portion relative to the first connecting portion around the central axis of the rotating shaft. The second movement direction is perpendicular to the first movement direction. The above three movement modes are randomly generated according to the positional angular relationship between the corner guard and the clamping assembly until the clamping assembly is adjusted to the accurate clamping position.

[0013] Through the corner guard removing device of the present disclosure, the first connecting portion and the second connecting portion are movably connected through two sets of slide rail and slider assemblies. When the corner guard pushes the second connecting portion to move along the first movement direction or the second movement direction, the second connecting portion undergoes a rotational movement. There are two rotation fulcrums between the first connecting portion and the second connecting portion. The distances from the two rotation fulcrums to the contact point between the corner guard and the clamping assembly are relatively far, and the force arms are long. Only a very small thrust can push the second connecting portion to rotate. The relative positions of the two rotation fulcrums can be adjusted in real time, and the adjustment angle is wide, enabling accurate adjustment of the position of the clamping assembly, and the two fixed arms of the corner guard can be correctly attached to the alignment retaining piece of the clamping assembly.

[0014] According to some embodiments, the reset member is a spring. During the process that the first driving member drives 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, a first guide rod parallel to the first linear guide rail is provided on the first connecting member, the spring is provided on the first guide rod, a first guide block is provided on the first connecting portion, and the end of the first guide rod is inserted into the guide hole of the first guide block. Preferably, a fixed block located between the two second connecting members is provided at the bottom of the second connecting portion, a second guide rod parallel to the second linear guide rail is provided on the fixed block, and the spring is provided on the second guide rod; a second guide block 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.

[0015] By providing springs for the first connecting part and the second connecting part, automatic reset of the first connecting part and the second connecting part can be achieved, and the second connecting part cannot swing randomly under the restrictive action of the spring force.

[0016] According to some embodiments, the follower unit includes a limiting mechanism; the limiting mechanism includes a limiting groove provided in the second connecting part, and a roller connected to the first connecting part is inserted into the limiting groove. The position of the roller provided on the first connecting part remains stationary, and the second connecting part moves relative to the first connecting part. When the inner groove edge of the limiting groove contacts the roller, the second connecting part can no longer deflect, and the follower deflection angle of the second connecting part is limited. Preferably, a cylinder is provided on the first connecting part, and a locking groove communicating with the limiting groove is provided in the second connecting 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 into the locking groove to lock the second connecting part, which can avoid the shaking of the working unit.

[0017] According to some embodiments, the clamping assembly includes a jaw cylinder fixed to the second connecting part, and an upper clamping plate and a lower clamping plate respectively connected to two fingers of the jaw cylinder. Two upwardly extending rectifying retaining pieces are provided on the lower clamping plate. After the edge of the corner guard fits with the rectifying retaining pieces, the jaw 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 connecting part. After the clamping assembly receives the thrust from the corner guard, the second connecting part, together with the clamping assembly and the cutting unit provided above it, retracts along the first movement direction, and the relative position between the clamping assembly and other mechanisms on the second connecting part remains unchanged, which is convenient for the debugging and stable operation of the equipment.

[0028] Unless the context requires otherwise, throughout the specification and claims, the word "comprising" and its variants, such as "comprises" and "having", should be understood in an open, inclusive sense, i.e., should be interpreted as "including, but not limited to".

[0029] Embodiment

[0030] As Figure 1 and 2 shown, the glue overflowing from the photovoltaic module A forms glue beads C between the corner guard B and the photovoltaic module A, which will cause the corner guard B to be skewed relative to the photovoltaic module A.

[0031] Generally, four corner guard removing devices are provided in the corner guard removing device, corresponding to the four corners of the photovoltaic module respectively. The photovoltaic module is aligned and positioned in the device, and the corner guard removing device approaches the corners of the photovoltaic module.

[0032] Figure 4 The photovoltaic module corner guard removing device shown in includes a working unit 100, a follower unit 200, and a driving unit 300 arranged in sequence from top to bottom.

[0033] The working unit 100 includes a clamping assembly 110 and a cutter unit 120. The clamping assembly is used to clamp the corner guard located at the corner of the photovoltaic module, and the cutter unit is used to cut the C-shaped tape of the corner guard. See Figure 3, the clamping assembly 110 includes a jaw cylinder 111, an upper clamping plate 112 and a lower clamping plate respectively connected to two fingers of the jaw cylinder. Two upwardly extending alignment stoppers 113 are provided on the lower clamping plate. After the edge of the corner guard fits against the alignment stoppers, the jaw cylinder drives the upper and lower clamping plates to clamp the corner guard. The cutter unit 120 includes two sets of cutter mechanisms respectively arranged on both sides of the clamping unit; the cutter mechanism includes a cutter cylinder 121 and a cutter assembly 122, and the cylinder drives the cutter assembly to move along the edge of the corner guard to cut the C-shaped tape.

[0034] The driving unit 300 includes a first driving member 310 that drives the working unit 100 to approach or move away from the corner guard along a first linear motion direction, and a second driving member 320 that drives the working unit 100 to rotate. Refer to Figure 4 , a third linear guide rail 500 is provided on the base platform 400 of the corner guard removing device. 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, and its cylinder body is fixed to 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 to the rotary table of the rotary cylinder.

[0035] As Figures 5 - 7 shown, the follower unit includes a first connecting portion 210 connected to the second driving member, and a second connecting portion 220 connected to the working unit. The clamping assembly 110 and the cutter unit 120 are fixed to the second connecting portion. Two first linear guide rails 230 parallel to the first motion direction D are provided at the top of the first connecting portion. A second linear guide rail 240 is provided at the bottom of the second connecting portion 220. A first connecting member 250 is slidably arranged on the first linear guide rail, and a second connecting member 260 is slidably arranged on the second linear guide rail. The first connecting member and the second connecting member are connected by a rotating shaft, so that two rotating fulcrums are formed between the first connecting portion 210 and the second connecting portion 220. Preferably, a thrust ball bearing 280 is provided 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.

[0036] In the initial state of the follower unit, the direction of the first linear guide rail is parallel to the first motion direction D, and the first linear guide rail 230 is perpendicular to the second linear guide rail 240. If the position of the corner guard B is accurate and does not skew relative to the photovoltaic module 2, the second connecting portion 220 will not deflect. If the corner guard B is skewed relative to the photovoltaic module A (as Figure 2As shown in the figure, one angular side of the corner guard first contacts the corresponding alignment stop piece 113. The clamping assembly 110 receives an oblique thrust from the corner guard. The two connecting pieces at the bottom of the second connecting part 220 rotate in the same direction, and the second connecting part will deflect relative to the first connecting part 210. Since the second connecting part is slidably connected to the second connecting piece 260, the second connecting part will translate relative to the second connecting piece, and the clamping assembly is quickly aligned by the corner guard. After the clamping assembly 110 is aligned, both angular sides of the corner guard B are attached to the alignment stop piece 113, the second connecting part 220 stops deflecting, and the clamping plate of the clamping assembly clamps the corner guard.

[0037] As Figure 7 As shown in the figure, after the second connecting part 220 deflects relative to the first connecting part 210, the second connecting part cannot automatically reset. Therefore, a resetting member is provided in the follower unit 200 in this embodiment. During the process of the first driving member 310 driving the working unit 100 away from the corner guard, the resetting member drives the first connecting part to gradually reset to the initial state.

[0038] The resetting member is a spring. During the process of the first driving member 310 driving 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 piece to reset along the first linear guide rail 230, and the second spring 263 drives the second connecting piece to reset along the second linear guide rail 240. During the translation process of the first connecting piece and the second connecting piece, the second connecting piece rotates around the fulcrum to align the second connecting part 220. After both angular sides of the corner guard B are attached to the alignment stop piece 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 table.

[0039] In some embodiments, a first guide rod 251 parallel to the first linear guide rail 230 is provided on the first connecting piece 250, a first spring 252 is provided on the first guide rod, a first guiding block 253 is provided on the first connecting part 210, and the end of the first guide rod is inserted into the guiding hole of the first guiding block. When the first connecting piece 250 retracts along the first linear guide rail 230, the first spring 252 is compressed. When the applied thrust gradually disappears, the first spring rebounds to drive the first connecting piece to move towards the photovoltaic module.

[0040] In some embodiments, a fixing block 261 located between the two second connecting pieces 260 is provided at the bottom of the second connecting part 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 guiding block 264 is provided on the second connecting piece, and the end of the second guide rod is inserted into the guiding hole of the second guiding block. When the second connecting part 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 part 220 to align.

[0041] As Figure 7 shown, the first connecting member 250 in the follower unit 200 moves to one end of the first linear guide 230 corresponding to the photovoltaic module, which is the maximum yaw angle of the clamping assembly 110 and the second connecting portion 220. In actual production applications, the corner guard will not be skewed at such a large angle. Therefore, in some embodiments, a limiting mechanism 290 for limiting the deflection angle of the clamping assembly 110 is provided in the follower unit 200. As Figure 6 shown, the limiting mechanism includes a limiting groove 291 provided in the second connecting portion, and two rollers 292 connected to the first connecting portion 210 are inserted into the limiting groove. The positions of the rollers remain stationary, and the second connecting portion 220 deflects relative to the first connecting portion 210. When the inner groove edge of the limiting groove contacts the rollers, the second connecting portion cannot continue to deflect, and the follow-up deflection angle is limited.

[0042] In some embodiments, a cylinder 293 is provided on the first connecting portion 210, and a locking groove 294 communicating with the limiting groove 291 is provided in the second connecting portion 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 rollers 292 into the locking groove to lock the second connecting portion 220, which can avoid the shaking of the working unit.

[0043] In summary, a photovoltaic module corner guard disassembly device provided in this embodiment has the advantages of a wider position adjustment angle of the clamping assembly, a smaller required thrust, and a higher position accuracy relative to the corner guard compared with the existing disassembly devices.
