Description

Technical Field

[0001] The present invention relates to the technical field of laminator rubber plate stretching, and more specifically to a bidirectional stretching device and method for a laminator rubber plate. Background Art

[0002] During the manufacturing process of solar panels, the rubber plate plays the roles of heating and pressing. On the one hand, the rubber plate can transfer heat quickly to ensure uniform temperature inside the panel, avoiding deformation or cracking caused by temperature differences, thereby ensuring stable power output of each panel. On the other hand, the rubber plate has good elasticity and toughness, and can keep the panel flat under high temperature and high pressure. In short, using a rubber plate can ensure the stability and quality of the product. At the same time, the rubber plate has become one of the important consumable parts in the laminator. To ensure production efficiency and work safety, the rubber plate needs to be replaced regularly during the use of the laminator.

[0003] However, currently, when replacing the rubber plate, there is no special device for pulling the rubber plate, making it extremely laborious for workers to pull the rubber plate during the process. At least 8 people are required to complete it. The process of pulling the rubber plate is time-consuming and laborious, usually carried out by workers' experience, lacking guidance on forming methods, and affecting the production progress.

[0004] Therefore, providing a bidirectional stretching device and method for a laminator rubber plate is an urgent problem that those skilled in the art need to solve. Summary of the Invention

[0005] In view of this, the present invention provides a bidirectional stretching device and method for a laminator rubber plate, which is easy to pull and replace, and improves efficiency and quality.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A bidirectional stretching device for a laminator rubber plate includes a rubber plate pressed between an upper box and a pressing frame, and further includes a pressing component and a tensioning component. The two adjacent short extension edges of the rubber plate are respectively pressed against the edge of the upper box through the pressing component, and the other two adjacent long extension edges of the rubber plate are respectively connected to the top plate of the upper box through the tensioning component.

[0008] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0009] The pressing component is used to fix the two adjacent short extension edges of the rubber plate, and the tensioning component is used to stretch the other two adjacent long extension edges of the rubber plate, realizing bidirectional stretching during the replacement of the laminator rubber plate. The operation is simple, time-saving and labor-saving, and the efficiency and quality are improved.

[0010] Further, the pressing assembly includes a first bent pressing plate and a blocking rod. The horizontal plate of the first bent pressing plate is fixed on the upper box, and the bottom end of the inclined plate of the first bent pressing plate presses against the short extended edge of the rubber plate. The blocking rod is inserted between the short extended edge and the inclined plate of the first bent pressing plate, or the blocking rod is inserted between the step of the short extended edge and the inclined plate of the first bent pressing plate.

[0011] The beneficial effect of adopting the above further technical solution is to realize the pressing of the short extended edge, and the blocking rod limits or blocks the short extended edge to prevent it from slipping out of the first bent pressing plate.

[0012] Further, the tensioning assembly includes a pull rod, a second bent pressing plate and a threaded connection member. The pull rod is located inside and in contact with the long extended edge. The horizontal plate of the second bent pressing plate is fixed on the pull rod, and the bottom end of the inclined plate of the second bent pressing plate presses against the outside of the long extended edge. The pull rod is connected to the top plate of the upper box through the threaded connection member.

[0013] The beneficial effect of adopting the above further technical solution is to realize the pressing and pulling actions on the long extended edge.

[0014] Further, the tensioning assembly further includes a knurled rod, and the knurled rod is fixed inside the inclined plate of the second bent pressing plate to press against the outside of the long extended edge.

[0015] The beneficial effect of adopting the above further technical solution is to increase the friction force and improve the pressing effect.

[0016] Further, the threaded connection member includes a nut and a bolt. The nut is fixed on the top plane of the pull rod. The screw of the bolt sequentially penetrates through the top plate of the upper box and the top plane of the pull rod from top to bottom, and the screw is threadedly connected to the nut.

[0017] A method for bidirectional stretching of a rubber plate of a laminator is carried out by using a bidirectional stretching device for a rubber plate of a laminator as described above, and includes the following steps:

[0018] 1) Curl the short extended edge of the rubber plate upward, and then fix the horizontal plate of the first bent pressing plate on the upper box through bolts, so that the bottom end of the inclined plate of the first bent pressing plate presses against the short extended edge of the rubber plate to complete the pressing of the short extended edge;

[0019] 2) Insert the blocking rod into the gap between the short extended edge and the inclined plate of the first bent pressing plate or insert the blocking rod into the gap between the step of the short extended edge and the inclined plate of the first bent pressing plate;

[0020] 3) Insert the long extension edge of the rubber plate between the pull rod and the second bent pressing plate. At the same time, the knurled rod presses against the long extension edge to complete the pressing of the long extension edge. Then rotate the screw to drive the pull rod to rise and drive the long extension edge to be pulled.
