Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic module production, and in particular to a clamping device for tearing off adhesive tape of photovoltaic modules. Background Art

[0002] During the production process of photovoltaic modules, a laminator is required to press the glass, EVA, battery cells, EVA and backplane together. Before lamination, in order to ensure the installation position of the various parts of the photovoltaic module, tape is usually pasted around the frame of the photovoltaic module before entering the laminator. After lamination is completed, the tape used for solidification needs to be torn off.

[0003] Among them, one end of the tape of the photovoltaic module frame will be exposed 3cm to 5cm from the edge of the photovoltaic module (one is to expose the tape end, so that it is easy to tear the tape off from the photovoltaic module, without manually finding the tape end directly from the photovoltaic module frame, and the other is that the exposed length cannot be too long to affect the normal processing of the photovoltaic module), and the exposed parts of the four groups of tapes around are exposed in a clockwise or counterclockwise manner. In the prior art, the tape is generally torn off manually.

[0004] In the prior art, some automated equipment has also appeared to perform tape tearing work. Chinese patent CN202110760013.9 discloses a double-glass tape tearing machine, which includes a frame, a conveyor line, a straightening component, a lifting device, a lower adsorption component, an upper adsorption component, a long-side tape tearing mechanism and a short-side tape tearing mechanism. The frame is equipped with a conveyor line, and the conveyor line is surrounded by straightening components. The frame below the conveyor line is equipped with a lifting device, and the lifting device is equipped with a lower adsorption component for adsorbing and fixing photovoltaic components. The upper part of the frame is provided with an upper adsorption component for clamping photovoltaic components. The conveyor line is also provided with a long-side tape tearing mechanism and a short-side tape tearing mechanism. Through the above method, the present invention has a compact structure and stable operation. It can replace manual automatic tape tearing, integrates conveying, tape clamping, tape winding and unloading, has a high degree of automation, saves a lot of working hours, reduces costs and increases efficiency, and improves production capacity. Although the patent discloses tape tearing equipment. However, during the process of tearing off the tape, especially when the tape is just clamped, it is very easy to break the tape because less tape ends leak out, resulting in failure in tearing off the tape. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, the present application provides a clamping device for tearing off the adhesive tape of a photovoltaic module.

[0006] The present application provides a clamping device for photovoltaic module tape tearing operation using the following technical solution:

[0007] A clamping device for the tape tearing operation of a photovoltaic module, comprising a clamping assembly. The clamping assembly includes a tape grasping mounting plate and a tape flattening mechanism and a tape clamping mechanism mounted on the tape grasping mounting plate. The tape flattening mechanism and the tape clamping mechanism are both driven by a clamping power mechanism. The output ends of the clamping power mechanisms of the tape flattening mechanism and the tape clamping mechanism respectively clamp the tape through a first clamping body and a second clamping body. The clamping surfaces of the first clamping body are all flat surfaces, and the clamping surfaces of the second clamping body adopt a convex table surface and a concave surface that are mutually engaged; a driving mechanism, which includes a tape clamping cylinder for adjusting the position of the clamping assembly. The output end of the tape clamping cylinder is connected to the tape grasping mounting plate. The bottom of the tape clamping cylinder is slidably connected to the mounting seat through a fixedly connected tape clamping cylinder mounting plate. And a servo motor for driving the tape clamping cylinder mounting plate to slide on the mounting seat is installed at the end of the mounting seat. The bottom of the mounting seat is slidably installed on the device cross beam (not shown in the figure) through a tape clamping mounting plate, and the bottom of the tape clamping mounting plate is locked to the device cross beam through a module locking seat.

[0008] By adopting the above technical solution, in the clamping assembly, the tape flattening mechanism mounted on the tape grasping mounting plate first straightens the tape head attached to the photovoltaic module, and then the tape clamping mechanism clamps the tape end at the same time. When tearing the tape, it can fully fit with the tape, evenly distribute the force of tearing the tape on the tape surface, and perform the tape tearing operation under the action of the driving mechanism, avoiding breaking the tape. The clamping surface of the first clamping body in the tape flattening mechanism uses a flat surface to straighten the end of the tape. The clamping surface of the second clamping body in the tape clamping mechanism adopts a design in which a convex and a concave groove are mutually engaged, increasing the clamping force and the degree of fitting of the tape, and improving the success rate of tape tearing. Adjust the position of the mounting seat in the driving mechanism according to the size of the photovoltaic module, slide and adjust the relative position with the device cross beam through the tape clamping mounting plate at the bottom of the mounting seat, and lock and fix it through the locking seat. Then adjust the tape clamping cylinder on the mounting seat, and the tape clamping cylinder adjusts the clamping assembly to the relative position corresponding to the photovoltaic module. When performing the tape tearing operation of the photovoltaic module, the tape clamping cylinder mounting seat at the bottom of the tape clamping cylinder is driven by the servo motor to move on the mounting seat, so as to tear the tape at the edge of the photovoltaic module.

A limiting groove for the up and down displacement of the rotating shaft is provided on the clamping block.

[0010] By adopting the above technical solution, the clamping power mechanism drives the movement of one end of the L-shaped clamping plate through the expansion and contraction of the driving cylinder installed in the clamping block. The corner of the L-shaped clamping plate, that is, its middle section, is rotatably connected to the clamping block. Thus, the end of the L-shaped clamping plate away from the driving cylinder realizes the clamping and release of the tape.

[0011] Preferably, the first clamping body is connected to the L-shaped clamping plate through a washer.

[0012] By adopting the above technical solution, the first clamping body clamps and straightens the tape under the action of the L-shaped clamping plate, and a washer is arranged between the first clamping body and the L-shaped clamping plate to adjust the clamping angle of the first clamping body, so that the first clamping body can fit and clamp the tape.

[0013] Preferably, both the convex table surface and the concave surface on the opposite surface of the second clamping body adopt a multi-layer structure.

[0014] By adopting the above technical solution, both the convex table surface and the concave surface on the opposite surface of the second clamping body adopt a multi-layer structure, which can further improve the clamping stability of the second clamping body on the tape and ensure the stability of clamping the tape during the tape tearing operation.

[0015] Preferably, the tape-grabbing mounting plate includes two sets of plate bodies with an acute included angle.

[0016] By adopting the above technical solution, the tape-grabbing mounting plate in the clamping mechanism adopts two sets of plate bodies with an acute included angle, which can avoid the edge of the clamping mechanism tearing the tape perpendicular to the tape end, facilitate pulling out the tape, and effectively avoid the situation of the tape end being broken.

A wire sleeve is installed at the bottom of the tape-clamping cylinder mounting plate, and the lead screw at the output end of the servo motor is in transmission cooperation with the wire sleeve.

[0018] By adopting the above technical solution, the annular tape-clamping cylinder mounting plate can stably perform the reciprocating operation of tape tearing on the mounting seat under the action of the servo motor.

[0019] Preferably, the tape-clamping mounting plate includes plate bodies located at the top and side of the device cross beam, and one side of the tape-clamping mounting plate close to the device cross beam is in transmission cooperation with the slide rail on the device cross beam through a slider.

[0020] By adopting the above technical solution, the tape-clamping mounting plate is in transmission with the cross beam on the device cross beam through the sliders on the top plate and the side plate, and after adjusting the position, the tape-clamping mounting plate is fixed on the device cross beam through the module locking seat, improving the stability of the entire clamping mechanism during the tape tearing process.

[0021] Preferably, the module locking seat is installed at the bottom of the tape-clamping mounting plate on the top of the device cross beam, and includes an L-shaped seat body and a locking screw penetrating through the bottom of the L-shaped seat body. A handle is installed at the outer end of the locking screw, and the inner end of the locking screw abuts against the device cross beam.

Both the tape-smoothing mechanism 111 and the tape-clamping mechanism 112 are driven by a clamping power mechanism 113. The output ends of the clamping power mechanisms 113 of the tape-smoothing mechanism 111 and the tape-clamping mechanism 112 respectively clamp the tape through a first clamp body 114 and a second clamp body 115. The clamping surfaces of the first clamp body 114 are all flat surfaces, and the clamping surfaces of the second clamp body 115 adopt a convex table surface and a concave surface that are mutually fitted; a driving mechanism 2, the driving mechanism 2 includes a tape-carrying cylinder 21 for adjusting the position of the clamping assembly 1. The output end of the tape-carrying cylinder 21 is connected to the tape-gripping mounting plate 11. The bottom of the tape-carrying cylinder 21 is slidably connected to a mounting seat 23 through a fixedly connected tape-carrying cylinder mounting plate 22. And a servo motor 231 for driving the tape-carrying cylinder mounting plate 22 to slide on the mounting seat 23 is installed at the end of the mounting seat 23. The bottom of the mounting seat 23 is slidably installed on a device crossbeam (not shown in the figure) through a tape-carrying mounting plate 24. And the bottom of the tape-carrying mounting plate 24 is locked to the device crossbeam through a module locking seat 241. In the clamping assembly 1, the tape-smoothing mechanism 111 mounted on the tape-gripping mounting plate 11 first straightens the tape head attached to the photovoltaic module, and then the tape-clamping mechanism 112 clamps the tape end at the same time. When tearing the tape, it can fully fit with the tape, evenly distribute the tape-tearing force on the tape surface, and perform the tape-tearing operation under the action of the driving mechanism 2, avoiding breaking the tape. Among them, the clamping surface of the first clamp body 114 in the tape-smoothing mechanism 111 uses a flat surface to straighten the tape head. The clamping surface of the second clamp body 115 in the tape-clamping mechanism 112 adopts a design in which a protrusion and a groove are mutually fitted, increasing the clamping force and the degree of fit with the tape, and improving the success rate of tape tearing. Adjust the position of the mounting seat 23 in the driving mechanism 2 according to the size of the photovoltaic module, slidably adjust the relative position with the device crossbeam through the tape-carrying mounting plate 24 at the bottom of the mounting seat 23, and lock it through the locking seat. Then adjust the tape-carrying cylinder 21 on the mounting seat 23, and the tape-carrying cylinder 21 adjusts the relative position of the clamping assembly 1 corresponding to the photovoltaic module.
