Description

Technical Field

[0001] The present application relates to the field of cloth pulling rods, and in particular to a folding locking pin used for fixing cloth pulling rods. Background Art

[0002] Lamination is an important process in the production of photovoltaic modules. It is the process of conveying the stacked cover plate, the first encapsulation film, the solar cell, the second encapsulation film and the back plate into the laminator, and melting the encapsulation film under high temperature and high pressure to encapsulate the cover plate, solar cell and back plate together. In the lamination process, the feeding and discharging of the lamination raw materials require the motor to drive the pull rod, which is pulled forward with the high-temperature cloth to ensure that the lamination raw materials can enter the specified position in the cavity to complete the lamination process.

[0003] The pull rod is an important part of the photovoltaic laminator for the inlet and outlet transmission of photovoltaic modules. Since photovoltaic modules are generally large in area, heavy in weight and have a long transmission distance, the high-temperature cloth needs to be replaced regularly due to long-term transmission wear. The high-temperature cloth is often fixed in the pull rod. For common pull rods, see Figure 1-a and Figure 1-b , respectively, are the top view and the front view of the pull rod. Step-shaped grooves are set at both ends of the pull rod to limit the sleeve rod. Figure 2 As shown, the bolt penetrates the groove wall and inner wall of the cloth pulling rod, clamps the sleeve rod in the cloth pulling rod to prevent the sleeve rod from moving, and the sleeve rod penetrates the high-temperature cloth to drive the high-temperature cloth. A specific cloth pulling rod is as shown in the Chinese utility model patent with application number 202222899236.6.

[0004] When replacing the high temperature cloth, all bolts or quick release pins need to be removed, the sleeve rod needs to be removed, and then a new high temperature cloth needs to be inserted, and all bolts or quick release pins need to be installed again. This operation is very time-consuming, and after multiple disassembly and assembly, it is very easy for the bolt thread to be damaged or the quick release pin ball to fall off, resulting in scrapping.

[0028] When replacing the high temperature cloth, all bolts or quick release pins need to be removed, the sleeve rod needs to be removed, and then a new high temperature cloth needs to be inserted, and all bolts or quick release pins need to be installed again. This operation is very time-consuming, and after multiple disassembly and assembly, it is very easy for the bolt thread to be damaged or the quick release pin ball to fall off, resulting in scrapping.

[0029] In order to solve the problems existing in the related technology, Figure 3-a FIG. 1 is a front view of a folding lock pin for fixing a cloth pulling rod provided by an embodiment of the present disclosure. Figure 3-b FIG. 1 is a top view of a folding lock pin for fixing a cloth pulling rod provided by an embodiment of the present disclosure. Figure 3-c , which is a left view of a folding lock pin for fixing a cloth pulling rod provided in an embodiment of the present disclosure.

[0030] The disclosed embodiment provides a folding lock pin for fixing a cloth pulling rod, comprising: a pin body 4 of a cylindrical pin, a plug 5 and a buckle 6, wherein a blind hole is respectively arranged on both sides of the plug 5, and the positions of the two blind holes are asymmetrical. The buckle 6 is connected to the plug 5 through the two blind holes. The buckle 6 is in a rectangular shape, and the position where the blind hole of the buckle 6 and the plug 5 are connected is one side of the rectangle where the buckle 6 is located. A convex buckle body is arranged on the opposite side where the rectangle where the buckle 6 is located is connected to the blind hole of the plug 5. The position where the buckle 6 is connected to the through hole of the plug 5 is at the midpoint of the long side of the rectangle where the buckle 6 is located. The convex buckle body is arranged at the midpoint of the long side of the rectangle where the buckle 6 is located. The convex buckle body is a semicircular arc.

[0031] In the embodiment of the present disclosure, the folding lock pin is improved, and the buckle 6 in the folding lock pin is set to be rectangular. When the sleeve rod needs to be fixed, the pin body 4 of the cylindrical pin is inserted into the cloth pulling rod 3, and the buckle 6 is fastened. One side of the rectangle where the buckle 6 is located can be stuck in the groove position of the cloth pulling rod 3 to lock the sleeve rod; when the folding lock pin is removed, the buckle 6 can be loosened by lightly pulling the buckle 6, and the folding lock pin can be pulled out.

[0032] See also Figure 4 The figure is a schematic diagram of an application of a folding lock pin to fasten a cloth pulling rod in an embodiment of the present disclosure. It should be understood that the width from the lower end surface of the top head 5 of the folding lock pin to the opposite side, that is, the width that the buckle 6 can accommodate, needs to be greater than or equal to the thickness of the groove wall 31. In this way, the groove wall 31 can completely enter the buckle 6. In practical applications, under normal circumstances, the width that the buckle 6 can accommodate can be greater than the groove wall 31 by 0.5mm to 2mm. In this way, it is easy to fasten the buckle 6, and the buckle 6 will not be too loose when fastened.

[0033] It should be noted that the common folding lock pin passes through the two ends of the buckle 6 through two asymmetric blind holes at the top 5. Since the two ends of the buckle 6 pass through two asymmetric positions, a deformation force is generated when the buckle 6 is swung back and forth. The above deformation force will generate an elastic force when the buckle 6 is swung. The elastic force can make the buckle 6 fully open or fully fastened, and not in an intermediate state. The present application utilizes the elasticity of the folding lock pin to make it easier to fasten and disassemble the folding lock pin.

[0034] The present application sets the buckle 6 of the folding lock pin into a rectangular shape. Under the premise that the buckle 6 can lock the groove of the cloth-pulling rod 3, the folding lock pin can be quickly installed and removed, thereby realizing the rapid installation and removal of the pin when the sleeve rod 2 is installed in the cloth-pulling rod 3.

[0035] The disclosed embodiment further provides a cloth-pulling rod system, comprising: a sleeve rod 2 and a cloth-pulling rod 3, wherein the cloth-pulling rod 3 further comprises the above-mentioned folding locking pin for fixing the cloth-pulling rod.

[0036] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
