Description

Technical Field

[0001] This utility model relates to a high-temperature cloth conveying device, and in particular to a high-temperature cloth conveying device for a solar cell module laminator used in the field of solar cell module encapsulation. Background Technology

[0002] A solar cell module laminator is a solar cell module encapsulation device. It provides a high-temperature vacuum environment to encapsulate various materials used in solar cell modules. With the rapid development of photovoltaic modules, improving production efficiency and reducing production costs have become the main development trends.

[0003] To address the issue of high-temperature fabric transmission, a solar cell module manufacturer in the market has adopted a design using a pull rod and chain, which has gained a certain market share.

[0004] As component sizes increase, laminators are also becoming larger. In existing technologies, pull rods are fixed to the transmission chain on both sides, and the chain drives the pull rods to move. The pull rods then drag the high-temperature fabric. Due to the different forces and stretching lengths on both sides of the chain, the high-temperature fabric is unevenly distributed in terms of weight and friction, which can easily cause problems such as wrinkles, misalignment, wear, and tearing. This affects component production and quality. Moreover, during the installation of the pull rods, workers need to enter the middle of the equipment to remove and install screws. The internal space of the laminator is compact, and the operation of changing the high-temperature fabric can also affect the personal safety of workers. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that as the size of the components increases, the current transmission method of pull rod plus chain is prone to problems such as wrinkles, deviation, wear and tear of high temperature cloth during use, and it is also easy to affect the personal safety of workers during the replacement of high temperature cloth.

[0006] To address the aforementioned problems, this utility model provides a high-temperature cloth conveying device for a solar cell module laminator, comprising two reinforcing layers fixedly connected to the upper end of the high-temperature cloth body. Two self-adhesive cloth strips are fixedly connected to the lower end of the high-temperature cloth body. Below the self-adhesive cloth strips are two drive chain groups. Multiple L-shaped mounting plates are fixedly connected to one end of each of the two longitudinally opposite drive chain groups. Self-adhesive cloth strips are fixedly connected to the upper ends of the multiple mounting plates. The self-adhesive cloth strips are bonded together. Two positioning components, corresponding to the two drive chain groups, are located at the upper end of the reinforcing layers. Each positioning component includes a mounting box placed on the upper end of the reinforcing layers, and the inner cavity of the mounting box contains a sliding plate. Multiple tension springs are fixedly connected between the upper end of the slide plate and the inner top wall of the mounting box. A pressure plate is provided at the upper end of the mounting box. Multiple pull rods corresponding to the multiple tension springs are fixedly connected at the lower end of the pressure plate. The lower ends of the pull rods pass through the mounting box and the adjacent tension springs in sequence and are fixedly connected to the upper end of the slide plate. Multiple limiting rods are fixedly connected to the lower end of the slide plate. The lower ends of the limiting rods pass through the reinforcing layer, the high-temperature cloth body, the self-adhesive strip one, the self-adhesive strip two, and the mounting plate in sequence. Limiting grooves are carved on the surface of the limiting rods. A positioning rod is provided in multiple limiting grooves. Two positioning blocks are movably sleeved on the outer surface of the positioning rod. The end of the positioning block away from the positioning rod is fixedly connected to the adjacent mounting plate.

[0007] In the aforementioned high-temperature cloth conveying device for solar cell module laminators, the fixing points of the high-temperature cloth body are evenly distributed on both sides of the high-temperature cloth body by means of self-adhesive cloth strip one and self-adhesive cloth strip two being bonded together. During the transmission process, the entire high-temperature cloth body is evenly stressed, effectively ensuring the stability of the transmission and thus effectively avoiding problems such as wrinkles, deviation, wear, and tearing of the high-temperature cloth body. Moreover, during the installation process, the staff does not need to enter the laminator, thereby effectively avoiding any impact on the personal safety of the staff.

[0008] As a further improvement of this application, the surface of the positioning block is chiseled with a movable groove, the positioning rod is located in the movable groove, and the height of the movable groove is greater than the diameter of the positioning rod.

[0009] As a further improvement of this application, the limiting groove is L-shaped, and the width of the limiting groove is greater than the diameter of the positioning rod.

[0010] As a further improvement of this application, the reinforcing layer is made of multiple layers of high-temperature fabric bonded together, and the length of the reinforcing layer is consistent with the width of the high-temperature fabric body.

[0011] As another improvement of this application, the four transmission chain groups are located at the four corners of the lower end of the high-temperature cloth body, and the transmission chain groups are formed by multiple transmission chains rotating end to end in pairs.

[0012] In summary, in practical applications, self-adhesive strip one and self-adhesive strip two are adhered together. The mounting box is then placed at an appropriate position above the reinforcing layer. Pushing the pressure plate downwards causes the sliding plate to move downwards, stretching the tension spring downwards and causing multiple limiting rods to move downwards, thus exposing the limiting grooves on the surface of the limiting rods. Rotating the positioning rod causes it to engage in the limiting groove. Releasing the pressure plate resets the sliding plate and limiting rods, and the limiting groove moves upwards with the limiting rod until its upper end is hidden. This provides secondary limiting and fixing of self-adhesive strip one and self-adhesive strip two, evenly distributing the fixing points of the high-temperature fabric body on both sides. During transmission, the entire high-temperature fabric body is evenly stressed, effectively ensuring transmission stability and preventing problems such as wrinkles, deviation, wear, and tearing of the high-temperature fabric body. Furthermore, during installation, workers do not need to enter the laminator, effectively avoiding any impact on their personal safety. Attached Figure Description

[0015] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0016] First implementation method: Figure 1 , Figure 2 and Figure 3The diagram shows a high-temperature cloth conveying device for a solar cell module laminator, comprising two reinforcing layers 1 fixedly connected to the upper end of the high-temperature cloth body. The reinforcing layers 1 are made of multiple layers of high-temperature cloth bonded together, and the length of the reinforcing layers 1 is consistent with the width of the high-temperature cloth body, effectively preventing damage to the high-temperature cloth body during operation. Two self-adhesive cloth strips 2 are fixedly connected to the lower end of the high-temperature cloth body. Two transmission chain groups 3 are provided below the self-adhesive cloth strips 2. The four transmission chain groups 3 are located at the four corners of the lower end of the high-temperature cloth body. The transmission chain groups 3 are formed by multiple transmission chains being connected end to end in pairs. Multiple L-shaped mounting plates 4 are fixedly connected to one end of the two longitudinally opposite transmission chain groups 3. The upper ends of the multiple mounting plates 4 are fixedly connected to self-adhesive cloth strips 5. Self-adhesive cloth strips 2 and 5 are bonded together, so that the high-temperature cloth body is fixed to the transmission chain groups 3, which facilitates the transmission of the entire high-temperature cloth body. Point A in the figure is the high-temperature cloth body.

[0017] During the transmission process of the high-temperature cloth body, self-adhesive strip 12 and self-adhesive strip 25 are bonded together. The reinforcing layer 1, the high-temperature cloth body, self-adhesive strip 12 and self-adhesive strip 25 are installed and fixed by multiple bolts. The high-temperature cloth body is moved by pulling the transmission chain group 3. When the high-temperature cloth is replaced, the bonding between self-adhesive strip 12 and self-adhesive strip 25 is opened, and the high-temperature cloth can be rolled up and pulled out from one side. The staff does not need to enter the equipment, which not only effectively avoids problems such as wrinkles, deviation, wear and tear of the high-temperature cloth body, but also improves the safety of the staff during operation.

[0018] Second implementation method: This embodiment adds a positioning component to the first embodiment, while the rest remains the same as the first embodiment.

[0019] Figure 4 , Figure 5 and Figure 6The diagram shows that the upper end of the reinforcing layer 1 is provided with two positioning components, each corresponding to one of the two transmission chain groups 3. Each positioning component includes a mounting box 6 placed on the upper end of the reinforcing layer 1. The inner cavity of the mounting box 6 is provided with a sliding plate 7. Multiple tension springs 8 are fixedly connected between the upper end of the sliding plate 7 and the inner top wall of the mounting box 6. The upper end of the mounting box 6 is provided with a pressure plate 9. Multiple pull rods 10, each corresponding to one of the multiple tension springs 8, are fixedly connected to the lower end of the pressure plate 9. The lower ends of the pull rods 10 sequentially pass through the mounting box 6 and the adjacent tension springs 8, and are fixedly connected to the upper end of the sliding plate 7. Pressing the pressure plate 9 can move the pull rods 10 downwards, causing the tension springs 8 to stretch downwards, and the sliding plate 7 and the limiting rod 11 also move downwards accordingly. Releasing the pressure plate 9 can reset the tension spring 8, causing the slide plate 7 and the limiting rod 11 to reset. The lower end of the slide plate 7 is fixedly connected to multiple limiting rods 11. The lower end of the limiting rod 11 moves through the reinforcing layer 1, the high-temperature cloth body, the self-adhesive strip 1 2, the self-adhesive strip 2 5, and the mounting plate 4 in sequence. The surface of the limiting rod 11 is chiseled with limiting grooves 12. The multiple limiting grooves 12 are all equipped with positioning rods 13. The outer surface of the positioning rod 13 is movably fitted with two positioning blocks 14. The end of the positioning block 14 away from the positioning rod 13 is fixedly connected to the adjacent mounting plate 4. The positioning rod 13 is inserted into the multiple limiting grooves 12, which can install and fix the reinforcing layer 1, the high-temperature cloth body, the self-adhesive strip 1 2, and the self-adhesive strip 2 5.

[0020] Figure 6 and Figure 7 As shown: the surface of the positioning block 14 is chiseled with a movable slot 15, the positioning rod 13 is located in the movable slot 15, and the height of the movable slot 15 is greater than the diameter of the positioning rod 13, so as to facilitate the rotation of the positioning rod 13. The limiting slot 12 is L-shaped, and the width of the limiting slot 12 is greater than the diameter of the positioning rod 13, so as to facilitate the positioning rod 13 to be inserted into the limiting slot 12.

[0021] When installing and fixing the reinforcing layer 1, the high-temperature cloth body, the self-adhesive strip 1 2, and the self-adhesive strip 2 5, the mounting box 6 can be placed at an appropriate position above the reinforcing layer 1. By pushing the pressure plate 9 downward, the sliding plate 7 moves downward, the tension spring 8 stretches downward, and multiple limiting rods 11 move downward, thus exposing the limiting groove 12 on the surface of the limiting rod 11. By rotating the positioning rod 13, the positioning rod 13 is inserted into the limiting groove 12. The pressure plate 9 is released, and the sliding plate 7 and the limiting rod 11 are reset. The limiting groove 12 moves upward with the limiting rod 11 until the upper end of the limiting groove 12 is hidden, thereby performing secondary limiting and fixing of the self-adhesive strip 1 2 and the self-adhesive strip 2 5. This not only simplifies the installation but also effectively improves the stability of the self-adhesive strip 1 2 and the self-adhesive strip 2 5 during use.

[0022] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
