Description

Technical Field

[0001] The utility model relates to the technical field of laminators, in particular to a photovoltaic component laminator and a cam quick-change heating module mechanism used therein. Background Art

[0002] Photovoltaic module laminators are one of the main equipment for preparing photovoltaic modules. They use a heating device to heat the photovoltaic modules. The structure of the heating device basically includes a heating plate and a heating module. The heating module is fixedly arranged under the heating plate and is fixedly connected to the heating plate. The heating module of a traditional laminator adopts a structure that is fixed to the bottom of the heating plate with multiple bolts. When installing and disassembling the heating module, the bolts need to be removed from the heating module and the heating plate. When installing the heating module, the bolts need to be installed one by one. This is not only time-consuming, but also requires installation and disassembly maintenance personnel to enter the bottom of the equipment to remove the bolts, which may cause bumps, burns and other injuries to the maintenance personnel. In particular, for multi-layer laminators, the space between the layers is limited, and the space under the heating plate is particularly small, making it impossible for maintenance personnel to enter to disassemble and install the heating module. Therefore, a new type of heating module disassembly and assembly structure is needed to meet the maintenance needs of the laminator. Utility Model Content

[0003] The purpose of the utility model is to provide a photovoltaic module laminator and a cam quick-change heating module mechanism used therein to address the shortcomings of the prior art laminators in which bolts are used to fix the heating module under the heating plate, making it inconvenient or even impossible to disassemble and assemble the heating module when replacing the heating module.

[0004] The technical solution of this utility model to solve the technical problem is as follows:

[0005] A cam quick-change heating module mechanism for a laminating machine includes a frame, a heating module, a heating plate, and a cam assembly. The heating plate is fixedly arranged on the top of the frame. The cam assembly includes a cam, a camshaft, and a camshaft driving device. The cam is fixedly arranged on the camshaft. The camshaft is rotatably arranged on the frame and located below the heating plate so that the cam is located below the heating plate. The heating module is located between the heating plate and the cam. The camshaft driving device drives the camshaft to rotate so that the cam rotates, pressing the heating module located between the heating plate and the top of the cam tightly under the heating plate or separating it from the heating plate.

[0006] At least two cam assemblies are included, and each camshaft is provided with at least two cams;

[0007] The camshaft driving device is a handwheel assembly, which includes a handwheel fixedly connected to a portion of the camshaft located outside the frame. The handwheel assembly also includes a cam locking and positioning device. When the cam rotates to clamp the heating module between the cam and the heating plate, the handwheel is fixed by the cam locking and positioning device.

[0008] The cam locking and positioning device includes a hand-tightening bolt limiting plate and a hand-tightening bolt. The hand-tightening bolt limiting plate is fixedly arranged on the frame body, a limiting groove is arranged on the hand-tightening bolt limiting plate, and a threaded through hole is arranged on the hand wheel. The position of the threaded through hole is adapted to the position after the cam is rotated. When the cam is in the position of clamping the heating module, the position of the threaded through hole is aligned with the limiting groove. By rotating the hand-tightening nut of the hand-tightening bolt, the screw is screwed into the limiting groove on the hand-tightening bolt limiting plate to lock the hand wheel position.

[0009] The handwheel assembly also includes a handle, a mounting seat is provided on the surface of the wheel disc, the handle is hingedly connected to the mounting seat via a hinge shaft, one end of the handle hinged to the handle mounting seat is a flat top forming a handle flat top, when the handle is rotated and is perpendicular to the plane of the wheel disc, the handle flat top is in contact with the wheel disc plane, so that when the handwheel is in use, the handle is perpendicular to the wheel disc plane, and when the handle is not in use, the handle can be parallel to the wheel disc plane;

[0010] A heating module installation structure is also provided, and the heating module installation structure includes guide rails, which are provided in pairs and are used to be slidably connected to the two opposite sides of the heating module. The guide rails are fixedly connected to the bottom of the heating plate, and the distance between the guide rail track surface and the bottom of the heating plate is greater than the height of the heating module. When the cam and the heating plate are pressed against the heating module, the heating module is separated from the track surface of the guide rail. When the cam releases the heating module, the guide rail can support the heating module.

[0011] The cams are consistent in size and shape and installed at the same angle;

[0012] The cam is one of a flat cam, a cylindrical cam, a curved cam, a special-shaped cam, a groove cam, and an eccentric cam.

[0013] A photovoltaic module laminating machine comprises the above-mentioned cam quick-change heating module mechanism for the laminating machine.

[0014] The advantages and beneficial effects of the utility model are:

[0015] The cam quick-change heating module mechanism and laminator using the structure of the utility model can change the distance between the cam and the heating module by changing the angle of the cam, thereby pressing the heating module against the bottom of the heating plate. When removing the heating module, only the angle of the cam needs to be changed to increase the distance between the heating module and the heating plate, so that the heating module is separated from the heating plate, and then the heating module can be pulled out from under the heating plate. Therefore, the overall operation of the mechanism is convenient, which greatly reduces the labor intensity of maintenance personnel and the downtime maintenance time of the equipment, thereby reducing the maintenance cost of the equipment. At the same time, the cam quick-change heating module mechanism uses the cam to support the heating module during the disassembly and assembly process. After assembly, the cam and the heating plate clamp the heating module. Maintenance personnel do not need to enter the bottom of the equipment to operate, which effectively reduces safety risks and can adapt to the spatial status of multi-layer laminators.

[0031] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be construed to limit the scope of protection of the present invention. The description is based on the actual location of the laminate assembly production line in actual application.

[0032] like Figure 1-Figure 5As shown, the laminating machine of the present invention includes a cam quick-change heating module mechanism, which comprises a cam assembly 1, a heating module 2, a heating plate 3, and a frame 4. The heating module is fixedly mounted below the heating plate via the cam assembly, and the heating plate is fixedly supported by the frame. The heating plate is used to heat the photovoltaic modules and support the modules during lamination.

[0033] The heating module can be a plate-shaped component that generates heat, such as an electric heating plate assembly or an electromagnetic heating plate assembly. The frame includes horizontal and vertical beams, with horizontal beams 41 and vertical beams 42 interlaced to form the frame body. The heating plate is fixed to the upper portion of the frame body. A support beam 43 is also provided on the horizontal or vertical beam, located on the side of the horizontal or vertical beam where the heating module is mounted. The heating module is first inserted between two opposing horizontal beams and supported by the support beam, positioning it between the heating plate and the cam. The cam assembly includes a cam 132, a camshaft 131, a camshaft drive, and a cam locking and positioning device. The camshaft is rotatably mounted to the underside of the frame's horizontal beams via bearing blocks 12, located below the heating plate. Each cam assembly is secured by two bearing blocks. Preferably, the bearing blocks are vertical bearing blocks to provide sufficient space for the cams to operate properly. The entire cam assembly is located below the heating plate. At least three cams are provided, arranged in a triangular pattern, forming a support surface for the heating module, which secures the heating module. One end of the fixed cam of the camshaft is located below the heating plate, and the other end of the camshaft is connected to the output end of the camshaft driving device. The end of the camshaft connected to the cam driving device is located outside the heating plate and the frame body for easy operation. At least two camshafts are provided. In this patent application, it is preferred that at least two cams are provided on a camshaft, and the installation angles of the cams are consistent, so that when the camshaft rotates, the heights of the cams on the same camshaft can be made consistent, so that when they are at the top, they all contact the heating module and press the heating module tightly. In this patent application, the camshaft driving device can be driven by an electric motor or by a handwheel assembly. The handwheel assembly preferably adopts the following structure, including a handwheel 112, a handwheel handle 111, and the cam locking and positioning device includes a hand-tightening bolt 113 and a hand-tightening bolt limit plate 114. The handwheel is fixedly arranged at one end of the camshaft connected to the camshaft drive device, the handwheel handle is arranged on the operating side of the handwheel, the hand-tightening bolt limit plate is arranged horizontally and fixedly arranged at a position of the frame corresponding to the height of the handwheel, the length direction of the hand-tightening bolt limit plate is preferably vertical to the length direction of the camshaft, a limit groove is arranged at a position of the hand-tightening bolt limit plate corresponding to the position of the handwheel, a threaded through hole is arranged on the handwheel, the threaded through hole is used to install the hand-tightening bolt, when the cam presses the heating module, the threaded through hole and the limit groove are opposite, the hand-tightening nut is rotated, the bolt rod of the hand-tightening bolt is screwed into the threaded through hole and the limit groove on the hand-tightening bolt limit plate, and the handwheel is locked and positioned to prevent the handwheel from rotating. Of course, the position of the threaded through hole on the handwheel must be compatible with the lifting position of the cam. When the cam lifts and tightens the heating module, the threaded through hole and the limit groove set on the hand-tightening bolt limit plate are exactly opposite.

[0034] It is best to set a handle mounting base 117 on the handwheel, and the handle is hingedly connected to the handle mounting base through a hinge shaft. The end of the handle hinged to the handle mounting base is a flat top to form a handle flat top. When the handle is rotated and is perpendicular to the plane of the wheel, the handle flat top is in contact and connected with the wheel plane, so that the handle is perpendicular to the wheel plane when the handwheel is in use. When the handle is not in use, the handle can be pressed down to make the handle parallel to the wheel plane, saving space.

[0035] After the heating module is installed, turn the handwheel to rotate the camshaft. When the cam protrusion on the camshaft rotates to the top, it presses against the heating module to secure it. To remove the heating module, reverse or continue rotating the camshaft until the top of the cam tilts, causing the heating module to fall and then be removed.

[0036] Each heating module requires two or more cams for fixation to ensure that the heating module plane is evenly stressed and prevent tilting.

[0037] The best solution is that the cams have the same shape and size and rotate synchronously, and when in the position of clamping the heating module, the raised parts of each cam are located at the top.

[0038] In a preferred solution, a heating module installation structure is also provided to prevent the heating module from shifting due to the friction with the cam during the rotation of the cam. The heating module installation structure includes a guide rail 44 provided above the crossbeam 41. The guide rails are provided in pairs. The upper portion of the guide rail is fixedly connected to the bottom of the heating plate 3. The length direction of the guide rail is perpendicular to the insertion direction of the heating module. The guide rail is slidably connected to the corresponding edge of the heating module. This can prevent the heating module from shifting due to the friction when the cam rotates when the heating module is fixed, affecting the accuracy of the heating plate position. The position of the heating module maintains the designed accuracy and ensures the uniformity of heating. A heat-insulating pad 43 is provided above the crossbeam and the longitudinal beam. The heating plate is fixedly connected to the crossbeam and the longitudinal beam through the heat-insulating pad. An insulation board is provided on the outside of the crossbeam and the longitudinal beam to prevent heat loss.

[0039] The following takes the camshaft drive device as an example of a handwheel to illustrate the overall working process of the laminating machine of the present invention: when the heating module needs to be replaced, remove the insulation board and the insulation pad at the corresponding position, turn the handwheel to rotate the cam, and during the rotation of the cam, the heating module gradually separates from the upper surface of the heating plate and is supported by the cam. When the cam rotates to a certain angle, the heating module falls on the guide rail and is supported by the guide rail. After the handwheel is rotated into place, it is completely separated from the heating module, and the heating module to be replaced is pulled out, and the new heating module is inserted into the guide rail. The handwheel is rotated in the opposite direction to make the cam lift the heating module until it rotates to the high part of the cam, and the heating plate and the cam clamp the heating module upward, and the insulation pad and the insulation board are placed and fixed to complete the replacement of the heating module. During replacement, the length of the guide rail is parallel to the length of the cam wheel and, therefore, perpendicular to the direction of cam rotation. Therefore, even if friction between the cam and the heating module causes the module to move, the guide rails' positioning limits ensure that the gap between the guide rails and the heating module is within the required range, typically 0.03mm. This allows for precise positioning of the heating module and prevents excessive displacement. Cam types include, but are not limited to, flat cams, cylindrical cams, curved cams, special-shaped cams, grooved cams, and eccentric cams.
