DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The tearing device can be used to automatically tear off the part of the workpiece that needs to be torn off. In the embodiment of the present invention, the workpiece and the part that needs to be torn off are not specifically limited. For example, the part of the workpiece that needs to be torn off can be: an isolation strip that matches the isolation pattern and is set on the surface of the workpiece.

[0037] Reference Figure 1 , Figure 1 The structure schematic diagram of a tearing device in an embodiment of the present invention is shown. The tearing device 100 may include: a frame 101, a clamping claw mechanism 102, a beam 103, and a support table 104. The frame 101 can provide support and support for the tearing of the part of the workpiece to be torn off. The number of the frames can be two or more. The beam 103 is arranged on the frame 101.

[0038] The clamping mechanism 102 is arranged on the crossbeam 103, and the support platform 104 is arranged on the frame 101. The support platform 104 and the crossbeam 103 are arranged opposite to each other, and the surface of the support platform 104 facing the crossbeam 103 is used to lay the workpiece 105. The workpiece can be, for example, a conductive metal foil. The function of the conductive metal foil is to collect the current of the back contact solar cell. The back contact solar cell has no main grid line on the front, and the positive and negative electrodes are both arranged on the back of the solar cell. The back contact solar cell can be an IBC cell (Interdigitated Back Contact, finger-shaped cross-back contact solar cell), an MWT cell (Metal Wrap Through, metal perforated winding cell), an EWT (Emitter Wrap Through, emitter perforated winding cell) cell, etc.

[0039] The material of the workpiece may be at least one of copper, silver, aluminum, nickel, magnesium, iron, titanium, molybdenum, tungsten and their alloys. For example, the material of the workpiece may be at least one of copper, silver, aluminum, nickel, magnesium, iron, titanium, molybdenum and tungsten. Alternatively, the material of the workpiece may be an alloy of at least two of copper, silver, aluminum, nickel, magnesium, iron, titanium, molybdenum and tungsten. Alternatively, the material of the workpiece may be a combination of at least one single substance and at least one alloy.

[0040] In the embodiment of the present invention, the thickness of the workpiece may be 5-200 microns. For example, the thickness of the workpiece may be 10-60 microns. In the embodiment of the present invention, this is not specifically limited.

[0041] In the embodiment of the present invention, a peeling strip matching the isolation pattern is provided on the surface of the workpiece. The peeling strip may be a portion of the workpiece that needs to be torn off. The peeling strip may be provided by laser etching, or by stamping, etc. In the embodiment of the present invention, this is not specifically limited.

[0042] Before laser etching or punching, since the thickness of the workpiece is small, a base material can be attached to one side of the workpiece, and the base material can play a supporting or bracing role to avoid warping caused by the small thickness of the workpiece. In order to avoid the loss of the base material, the thickness of the stripping strip can be equal to or less than the thickness of the workpiece. For example, the thickness of the stripping strip can be 30% to 90% of the thickness of the conductive foil.

[0043] Optionally, the isolation pattern may include: a zigzag line or an arc line. The width of the zigzag line or the arc line may be greater than 50 microns, such as 200 microns or greater. After the peeling strip corresponding to the isolation pattern on the workpiece is torn off, the workpiece with isolation is obtained to isolate the positive and negative electrodes of the back contact solar cell to avoid short circuit.

[0044] In the embodiment of the present invention, after the whole peeling strip is torn off, the whole workpiece can be divided into 60 or 72 adjacent regions, each of which can correspond to a back contact solar cell. Each region is connected to each other through the remaining workpiece, so that each back contact solar cell is connected in series, and the lines of several adjacent regions can form an X-shaped joint at the center corner, thereby reducing the number of required starts. The area of ​​each region can be 1.635m 2 (0.991m×1.650m) and 1.938m 2 (0.991 m×1.956 m). In the embodiment of the present invention, no specific limitation is made to this.

[0045] In the embodiment of the present invention, the surface of the workpiece is also provided with a conductive site, which is a point where the workpiece is electrically connected to the negative electrode fine grid line and the positive electrode fine grid line of the back-contact solar cell backlight surface. Alternatively, the conductive site is a point where the workpiece is electrically connected to the negative electrode, positive electrode, etc. of the back-contact solar cell backlight surface. In the embodiment of the present invention, this is not specifically limited.

[0046] Reference Figure 2 , Figure 2 A schematic diagram of a workpiece provided with a peeling strip in an embodiment of the present invention is shown. Figure 2 10 may be a conductive site on the workpiece. 11 may be a peeling strip. After the peeling strip is torn off, a gap is formed. Through the gap, the conductive site of the workpiece that is in electrical contact with the positive electrode of the back contact solar cell and the conductive site that is in electrical contact with the negative electrode of the back contact solar cell are isolated on both sides of the gap to avoid short circuit.

[0047] The clamping claw structure 102 is used to grab the part of the workpiece 105 that needs to be torn off, and lift the part of the workpiece 105 that needs to be torn off in a direction perpendicular to the support platform 104, thereby tearing off the part of the workpiece 105 that needs to be torn off.

[0048] Reference Figure 3 As shown, Figure 3 The schematic diagram of the structure of a clamping structure in an embodiment of the present invention is shown. The clamping structure 102 includes: at least one first clamping jaw 1021 and at least one second clamping jaw 1022. The first clamping jaws 1021 can be arranged in parallel, and the second clamping jaws 1022 can be arranged in parallel, so that multiple parts of the workpiece that need to be torn off can be grasped at the same time for tearing off, which can improve the tearing efficiency.

[0049] In the embodiment of the present invention, the first clamping jaw 1021 and the second clamping jaw 1022 have a height difference in a direction perpendicular to the support platform 104, and the second clamping jaw 1022 is located above the first clamping jaw 1021. That is, in a direction perpendicular to the support platform, the first clamping jaw 1021 is closer to the support platform, and the second clamping jaw 1022 is farther from the support platform 104. The first clamping jaw 1021 can first grab the part of the workpiece that needs to be torn off and rise in the vertical direction, so that the second clamping jaw 1022 can grab the part of the workpiece that needs to be torn off, and the second clamping jaw 1022 continues to grab the part of the workpiece that needs to be torn off and rises in the vertical direction, and then tears off the part that needs to be torn off under uniform force.

[0050] In the embodiment of the present invention, at the same time, each first clamping jaw is in the same working state or different working states. At the same time, each second clamping jaw is in the same working state or different working states. In the embodiment of the present invention, this is not specifically limited.

[0051] In the present invention, the clamp mechanism is used to grab the part of the workpiece that needs to be torn off and is fixed on the support platform facing the surface of the beam. The first clamp and the second clamp grab the part of the workpiece that needs to be torn off and move in the vertical direction, thereby tearing off the part of the workpiece that needs to be torn off, and realizing mechanized and automatic tearing. In addition, the first clamp and the second clamp can tear off the part that needs to be torn off under uniform force, thereby largely avoiding the part that needs to be torn off from being torn off during the tearing process, without the need for multiple tearing, and high production efficiency. At the same time, by continuously tearing off the first clamping jaw and the second clamping jaw with a height difference in the vertical direction, at least two clamping jaws are needed to realize the tearing off of the part to be torn off on the workpiece; and multiple clamping jaws can tear off the parts to be torn off on multiple workpieces or multiple parts of a workpiece at the same time, so the production efficiency is high; the tearing device can also adjust the angle according to the actual situation of the part to be torn off on the workpiece, not only can it tear off the part to be torn off in a larger area, but the clamping jaw mechanism can also tear off the part to be torn off along the setting direction of the part to be torn off. During the tearing process, the part to be torn off is subjected to more uniform force, thereby being able to largely avoid the part to be torn off from being torn off during the tearing process, without the need for multiple tearing, so the production efficiency is high; further, the tearing device has only two types of clamping jaws, which is convenient for the manufacture of standard parts, reduces production costs, and is convenient for maintenance.

[0052] Optionally, both the first clamp 1021 and the second clamp perform a grabbing action on the portion of the workpiece 105 that needs to be torn off. The grabbing action includes a grabbing and lifting action, and a loosening and lowering action. The grabbing and lifting action is: the clamp grasps the portion of the workpiece that needs to be torn off, and lifts the portion that needs to be torn off to keep it away from the workpiece, and then tears the portion that needs to be torn off from the workpiece. The loosening and lowering action is: the clamp remains relaxed, and in the relaxed state, the clamp releases the portion of the workpiece that needs to be torn off, and approaches the workpiece to prepare for continued tearing.

[0053] Optionally, when the clamps grasp the part of the workpiece to be torn off, at any time, at least one of the first clamps or at least one of the second clamps is performing a grasping and lifting action. In other words, at any time when the clamps grasp the part of the workpiece to be torn off, there is a need for the clamps to grasp and lift the part to be torn off, so as to prevent the part of the workpiece to be torn off from falling due to gravity when it is not grasped.

[0054] Optionally, the grasping action includes the following steps: the first jaw synchronously performs a grasping and lifting action, when the second jaw synchronously performs a grasping and lifting action, the first jaw synchronously performs a loosening and lowering action, the second jaw synchronously performs a grasping and lifting action, when the first jaw synchronously performs a grasping and lifting action, the second jaw synchronously performs a loosening and lowering action.

[0055] Specifically, when each second jaw has not yet grasped the part to be torn off, each first jaw grasps the part to be torn off at the same time, and synchronously lifts the part to be torn off, and each second jaw can be in a relaxed state. After the second jaw can reach the part to be torn off, each second jaw grasps the part to be torn off at the same time, and synchronously lifts the part to be torn off. When each second jaw grasps and lifts the part to be torn off at the same time, each first jaw can synchronously perform a relaxing and descending operation. When each first jaw synchronously performs a grasping and lifting action, each second jaw can synchronously perform a relaxing and descending operation. Furthermore, each first jaw and each second jaw alternately perform a grasping and lifting action and a relaxing and descending action, and in a smaller working space, the part to be torn off can be completely torn off from the workpiece.

[0056] In the embodiment of the present invention, each first clamp and second clamp can be lifted at a uniform speed during the grasping and lifting action, which can further make the part to be torn off be subjected to more uniform force during the grasping and lifting process, and can further avoid the part to be torn off from being torn off during the tearing process, without the need for multiple tearing, and the production efficiency is high.

[0057] Reference Figure 4 , Figure 4A partial structural diagram of a clamping jaw in an embodiment of the present invention is shown. Figure 4 As shown, the clamp may include: a clamp cylinder 1023, a servo mechanism ( Figure 4 The upper chuck 1024 and the lower chuck 1025 are flat plates arranged in parallel and opposite to each other. The upper chuck 1024 and the lower chuck 1025 clamp the part of the workpiece that needs to be torn off. The upper chuck 1024 and the lower chuck 1025 are flat plates arranged in parallel and opposite to each other. The pressure acting on the part of the workpiece that needs to be torn off is relatively small, so that the part of the workpiece that needs to be torn off can be subjected to more uniform force during the grasping and lifting process, thereby largely avoiding the part of the workpiece that needs to be torn off from being torn off during the tearing process, without the need for multiple tearing, and high production efficiency.

[0058] The clamping jaw cylinder 1023 is used to control the opening and closing of the upper clamp 1024 and the lower clamp 1025. Specifically, before grabbing the part of the workpiece to be torn off, the clamping jaw cylinder 1023 is used to control the upper clamp 1024 and the lower clamp 1025 to open. After the part of the workpiece to be torn off is placed between the upper clamp 1024 and the lower clamp 1025, the clamping jaw cylinder 1023 is used to control the upper clamp 1024 and the lower clamp 1025 to close. The servo mechanism is used to control the rise or fall of the clamp, providing a relatively uniform power for the rise or fall of the clamp.

[0059] Optionally, the crossbeam includes at least two groups of rotatable bases, and the above-mentioned clamping structure is arranged on the crossbeam through the rotatable base, and the rotatable base is used to rotate the clamping mechanism. Furthermore, the clamping structure can have a larger deflection angle on the crossbeam through the above-mentioned rotatable base, and the angle of the clamping mechanism can be adjusted according to the specific situation of the part to be torn off on the workpiece. On the one hand, the clamping mechanism can tear off the part to be torn off in a larger area, and on the other hand, the clamping mechanism can tear off the part to be torn off along the setting direction of the part to be torn off through the above-mentioned rotatable base. During the tearing process, the part to be torn off is subjected to more uniform force, thereby being able to largely avoid the part to be torn off from being torn off during the tearing process, without the need for multiple tearing, and high production efficiency.

[0060] Optionally, the rotatable base is rotated, and the angle between the first clamping jaw of the clamping jaw mechanism and the vertical direction is 45°. When the angle between the first clamping jaw and the vertical direction is 45°, the first clamping jaw can tear off the part of the workpiece to be torn off with a small force, thereby largely avoiding the part to be torn off during the tearing process, eliminating the need for multiple tearing, and achieving high production efficiency.

[0061] Optional, see Figure 1As shown, a first guide rail ( Figure 1 (not shown in the figure), the rotatable base can be slidably set on the first guide rail. Then, the above-mentioned clamping jaw structure not only realizes the angle deflection through the rotatable base and the above-mentioned first guide rail, but also can move along the axial direction of the crossbeam. On the one hand, the clamping jaw mechanism can tear off a larger area of ​​the part that needs to be torn off. On the other hand, the clamping jaw mechanism can continuously adjust the tearing direction according to the setting direction of the part that needs to be torn off at various positions on the workpiece through the above-mentioned rotatable base and the first guide rail, and tear off the part that needs to be torn off along the setting direction of the part that needs to be torn off. During the tearing process, the part that needs to be torn off is subjected to more uniform force, thereby being able to avoid the part of the workpiece that needs to be torn off from being torn off during the tearing process to a large extent, without the need for multiple tearing, and high production efficiency.

[0062] In the embodiment of the present invention, optionally, the first guide rail and the rotatable base may be powered by a power assembly, and the power assembly may be a motor, etc. In the embodiment of the present invention, no specific limitation is made to this.

[0063] In the embodiment of the present invention, optionally, a second guide rail 1011 is further provided on the frame 101, and the beam 103 is arranged on the frame 101 through the second guide rail 1011, that is, the beam 103 can move along the second guide rail 1011, and then, driven by the beam 103, the above-mentioned clamping mechanism can also move along the second guide rail 1011, and the clamping mechanism can tear off a larger area of ​​the part that needs to be torn off.

[0064] In the embodiment of the present invention, the frame 101 is further provided with a second guide rail 1011, and the crossbeam 103 is provided on the frame 101 through the second guide rail 1011. The first guide rail is provided along the axial direction of the crossbeam. Therefore, the second guide rail 1011 is perpendicular to the first guide rail, and the second guide rail 1011 does not intersect with the first guide rail 1011, that is, the movement of the first guide rail and the second guide rail 1011 will not interfere with or affect each other. The second guide rail 1011 can be driven to move by a reduction motor, and this is not specifically limited in the present invention.

[0065] In the embodiment of the present invention, optionally, refer to Figure 5 , Figure 5 A schematic diagram of another tearing device structure in an embodiment of the present invention is shown. Figure 1On the basis of: a suction structure 1041 is provided on the support table 104. The suction structure 1041 is used to suction the workpiece 105 on the support table 104, so that the workpiece 105 is flat on the support table. Since the workpiece 105 is thin and usually easy to warp, the suction structure 1041 can be used to easily and flatly place the workpiece 105 on the support table 104, so as to facilitate the tearing off of the part to be torn off.

[0066] The adsorption mechanism 1041 is also used to adsorb the torn part that needs to be torn off. Specifically, after the torn part needs to be torn off, it can be adsorbed on the adsorption structure 1041, which is conducive to collecting the torn part that needs to be torn off.

[0067] In the embodiment of the present invention, optionally, the adsorption structure may include: a suction cup or a vacuum adsorption structure to simply realize the adsorption function.

[0068] In the present invention, the clamp mechanism is used to grab the part of the workpiece that needs to be torn off and is fixed on the support platform facing the surface of the beam. The first clamp and the second clamp grab the part of the workpiece that needs to be torn off and move in the vertical direction, thereby tearing off the part of the workpiece that needs to be torn off, and realizing mechanized and automatic tearing. In addition, the first clamp and the second clamp can tear off the part that needs to be torn off under uniform force, thereby largely avoiding the part that needs to be torn off from being torn off during the tearing process, without the need for multiple tearing, and high production efficiency. At the same time, by continuously tearing off the first clamping jaw and the second clamping jaw with a height difference in the vertical direction, at least two clamping jaws are needed to realize the tearing off of the part to be torn off on the workpiece; and multiple clamping jaws can tear off the parts to be torn off on multiple workpieces or multiple parts of a workpiece at the same time, so the production efficiency is high; the tearing device can also adjust the angle according to the actual situation of the part to be torn off on the workpiece, not only can it tear off the part to be torn off in a larger area, but the clamping jaw mechanism can also tear off the part to be torn off along the setting direction of the part to be torn off. During the tearing process, the part to be torn off is subjected to more uniform force, thereby being able to largely avoid the part to be torn off from being torn off during the tearing process, without the need for multiple tearing, so the production efficiency is high; further, the tearing device has only two types of clamping jaws, which is convenient for the manufacture of standard parts, reduces production costs, and is convenient for maintenance.

[0069] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0070] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present invention.

[0071] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
