Technical Field

[0001] This utility model relates to the technical field of glass paper laying machines, and more particularly to a pressure plate assembly and a paper laying machine. Background Technology

[0002] During the glass stacking process, a release liner needs to be laid between adjacent glass panes. The release liner is then cut with a cutter to meet dimensional requirements. In related technologies, when the cutter cuts the release liner, it performs a secondary cut on the already cut and stacked release liner, generating fine paper scraps. If these paper scraps remain in the stacked glass, they can damage and render the photovoltaic modules produced from the glass unusable, affecting the glass production process. Utility Model Content

[0012] According to some embodiments of the present invention, the lower pressure plate also has a plurality of openings, which are disposed on the second pressing part and spaced apart along a third direction.

[0035] The pressure plate assembly of a first aspect embodiment and the paper laying machine of a second aspect embodiment of the present invention will now be described with reference to the accompanying drawings. It should be noted that, for ease of description and understanding, in the embodiments of the present invention and the accompanying drawings, the up-down direction is indicated as the first direction, the front-back direction as the second direction, and the left-right direction as the third direction. The first, second, and third directions intersect each other. In practical applications of the pressure plate assembly and the paper laying machine, the first, second, and third directions may also be other directions.

[0036] A first aspect of this utility model provides a pressure plate assembly 100 for cutting release paper 400, see reference. Figure 1As shown, the pressure plate assembly 100 includes a base 110, a plate 120, and a pressure block 130. The base 110 serves as the carrier of the pressure plate assembly 100, and both the plate 120 and the pressure block 130 are connected to the base 110. The plate 120 has an upper pressure plate 121 and a lower pressure plate 122, which are arranged vertically and movably connected to the base 110. Along the front-rear direction, the upper pressure plate 121 extends to form a first pressing portion 1211, and the lower pressure plate 122 extends to form a second pressing portion 1221. The first pressing portion 1211 and the second pressing portion 1221 can move relative to each other to jointly clamp the release paper 400 that needs to be cut. The pressure block 130 is connected to the lower pressure plate 122 and is disposed along the vertical direction on the side of the second pressing part 1221 opposite to the first pressing part 1211. The pressure block 130 and the second pressing part 1221 are spaced apart. The pressure block 130 is used to abut against the previously cut release paper 400, separating the cut release paper 400 from the release paper 400 that needs to be cut, thereby preventing the cut release paper 400 from being cut a second time. The first pressing part 1211, the second pressing part 1221 and the pressure block 130 can move relative to the base 110 in a first direction, so that the pressure plate assembly 100 can switch between a first position and a second position.

[0037] Specifically, when stacking glass 300, a release paper 400 needs to be placed between two adjacent stacked glass 300. When laying the release paper 400, it needs to be laid flat on the surface of the glass 300, and then a portion is cut from a whole sheet or a roll of release paper 400 by a cutting component 200 such as a cutter to separate the two adjacent glass 300.

[0038] In one example, see Figure 1 and Figure 5As shown, the release paper 400 is disposed between the first pressing part 1211 and the second pressing part 1221. When the release paper 400 needs to be laid, it is pulled out from between the first pressing part 1211 and the second pressing part 1221 to cover the glass 300. Then, the first pressing part 1211, the second pressing part 1221 and the pressing block 130 move downward relative to the base 110, so that the first pressing part 1211 and the second pressing part 1221 can jointly clamp the release paper 400 to be laid and cut, and so that the pressing block 130 abuts against the previously stacked and cut release paper 400. At this time, the pressure plate assembly 100 is in the first position. Since the second pressing part 1221 and the pressing block 130 are both disposed on the lower pressing plate 122, and the lower pressing plate 122 is disposed below the upper pressing plate 121, the downward movement distance of the first pressing part 1211 is greater than the movement distance of the second pressing part 1221, so that the first pressing part 1211 and the second pressing part 1221 can abut against each other. After moving to the first position, the release paper 400 to be laid needs to be cut by the cutting component 200. Since the pressing block 130 and the second pressing part 1221 are spaced apart, and the pressing block 130 abuts against the release paper 400 that has been stacked and cut, the cutting component 200 will not perform secondary cutting on the release paper 400 that has been stacked and cut during the cutting process, thereby avoiding the generation of paper scraps.

[0039] After the release paper 400 is laid, a new piece of glass 300 is placed on top of it, and then a new release paper 400 is laid on top of this new glass 300. At this time, the first pressing part 1211, the second pressing part 1221, and the pressing block 130 move upward relative to the base 110 until the pressing block 130 is above the release paper 400 that has just been cut. The first pressing part 1211 and the second pressing part 1221 separate, and the pressure plate assembly 100 is in the second position. Then, the new release paper 400 is pulled out from between the first pressing part 1211 and the second pressing part 1221 and placed on top of the new glass 300. The pressing block 130 is then driven to descend and abut against the release paper 400 that has just been cut, and then the cutting is completed. This cycle is repeated to complete the stacking of the glass 300s.

[0040] In related technologies, when the cutting component 200 cuts the release liner 400, the cutting blade of the cutting component 200 performs a secondary cut on the already cut and stacked release liner 400, thereby generating fine paper scraps. Because the paper scraps are extremely fine, once they get mixed into the release liner 400, they cannot be completely removed by conventional cleaning methods. Furthermore, since the production of photovoltaic glass 300 has stringent standards for the cleanliness of the production environment and raw materials, these fine paper scraps may affect the quality of the glass 300, or even damage and render it unusable.

[0041] Compared to related technologies, the pressure plate assembly 100 of this utility model embodiment moves vertically relative to the base 110 through the first pressing part 1211, the second pressing part 1221 and the pressing block 130. When the release paper 400 needs to be cut, the first pressing part 1211 and the second pressing part 1221 jointly clamp the release paper 400 to be cut, while the pressing block 130 can abut against the release paper 400 that has been cut previously, thereby increasing the distance between the release paper 400 to be cut and the release paper 400 that has been cut, thereby avoiding the cutter from making a second cut on the release paper 400 that has been cut.

[0042] In some embodiments, see Figures 1 to 4 As shown, the pressure plate assembly 100 includes a plurality of pressure blocks 130. The plurality of pressure blocks 130 are spaced apart along the left-right direction on the lower pressure plate 122, thereby providing pressure over a wide range on the cut release paper 400, ensuring that the release paper 400 in different positions is fixed. Specifically, see [reference needed]. Figure 5 As shown, in the top-to-bottom direction, when the cutting component 200 cuts the first layer of release paper 400, the pressure block 130 abuts against the edge of the second layer of release paper 400, causing the edge of the second layer of release paper 400 to bend downwards, thereby increasing the gap between the first layer of release paper 400 (the release paper 400 being cut) and the second layer of release paper 400 (the release paper 400 that has been cut). By setting multiple pressure blocks 130, the edges of the release paper 400 can be covered and pressed, preventing the edges of the second layer of release paper 400 from lifting and causing secondary cutting.

[0043] Furthermore, in some embodiments, the spacing between any two adjacent pressure blocks 130 is the same. Specifically, by setting the spacing between any two adjacent pressure blocks 130 to be the same, the pressure blocks 130 can apply consistent pressure at different locations, ensuring that the cut release paper 400 receives the same support force at all points, thus avoiding warping of the release paper 400 caused by localized stress concentration. This ensures the compressive stability of the pressure blocks 130 on the cut release paper 400, improving the cutting efficiency of the release paper 400 and the stacking efficiency of the glass 300.

[0044] In some embodiments, see Figure 3 and Figure 5 As shown, the pressing block 130 extends in the front-back direction, giving it a first length L1. The second pressing part 1221 is also arranged in the front-back direction, and the length of the second pressing part 1221 is a second length L2, where the first length L1 is greater than the second length L2.

[0045] Specifically, along the front-to-back direction, the length of the pressing block 130 is greater than the length of the second pressing part 1221. The lengths of the first pressing part 1211 and the second pressing part 1221 are the same. Since the first pressing part 1211 and the second pressing part 1221 together clamp the release paper 400 during its laying, the cutting assembly 200 needs to cut the release paper 400 on the side of the first pressing part 1211 and the second pressing part 1221 facing the stacked glass 300. Making the first length L1 greater than the second length L2 ensures that the pressing block 130 can contact the previously cut release paper 400 when moving downwards, and also increases the distance between the second pressing part 1221 and the stacked glass 300, thus facilitating the cutting assembly 200's cutting of the release paper 400 and avoiding interference between the second pressing part 1221 and the cutting assembly 200.

[0046] In some embodiments, see Figure 1 and Figure 2 As shown, the lower pressure plate 122 also has multiple openings 1222, which are disposed on the second pressing part 1221 and spaced apart in the left-right direction. The openings 1222 respectively guide the upper and lower sides of the second pressing part 1221 in the vertical direction and the side of the second pressing part 1221 away from the base 110 in the front-back direction, i.e., the front side of the base 110. Specifically, when the glass 300 is stacked, the side of the second pressing part 1221 away from the base 110 is the side facing the glass 300. Since the release paper 400 needs to be laid on the glass 300, and the release paper 400 is disposed between the first pressing part 1211 and the second pressing part 1221, when the release paper 400 needs to be laid, it needs to be pulled out from between the first pressing part 1211 and the second pressing part 1221 by a clamping device. The opening 1222 of the lower pressure plate 122 corresponds to the clamping area of ​​the clamping device. During installation, the release paper 400 is placed on the opening 1222, and the clamping device clamps the release paper 400 through the opening 1222, thereby pulling the release paper 400 out between the first pressing part 1211 and the second pressing part 1221. By providing the opening 1222, contact between the clamping device and the second pressing part 1221 can be avoided, preventing interference between their movements, thereby improving the efficiency of laying and cutting the release paper 400.

[0047] Further, see Figure 2 and Figure 4 As shown, the upper pressure plate 121 includes a plurality of first pressing parts 1211, which are spaced apart in the left-right direction, and the plurality of first pressing parts 1211 correspond to a plurality of openings 1222. The number and position of the first pressing parts 1211 correspond to the number and position of the openings 1222, respectively.

[0048] Specifically, by setting multiple first pressing parts 1211, multiple positions of the release paper 400 can be pressed, thereby improving the clamping effect of the upper pressure plate 121 and the lower pressure plate 122. Above the opening 1222 of the second pressing part 1221, a corresponding first pressing part 1211 is provided. The corresponding positions of the first pressing parts 1211 and the opening 1222 allow the first pressing parts 1211 to press the release paper 400 at the opening 1222 flat. When the release paper 400 needs to be pulled out from between the first pressing parts 1211 and the second pressing parts 1221 for laying, the clamping device can better contact the release paper 400 to clamp the release paper 400 at the opening 1222, thereby further improving the laying and cutting efficiency of the release paper 400.

[0049] Further, see Figure 2 and Figure 4 As shown, the first pressing part 1211 is divided into a first part 1212 and a second part 1213 along the left-right direction, and the first part 1212 and the second part 1213 are connected. The first part 1212 corresponds to the opening 1222 along the up-down direction, thereby blocking the opening 1222 in the up-down direction. The second part 1213 corresponds to the second pressing part along the up-down direction, so that in the second position, the second part 1213 abuts against the second pressing part.

[0050] Specifically, in one embodiment, the first part 1212 and the second part 1213 have the same width in the left-right direction. By aligning the first part 1212 and the second part 1213 with the opening 1222 and the pressing part 1221 respectively, when laying the release paper 400, the first part 1212 can press against the release paper 400 located at the opening 1222, thereby ensuring the stability of the release paper 400 at the opening 1222 and facilitating the clamping device's gripping of the release paper 400. Simultaneously, the second part 1213 and the pressing part 1221 clamp and fix the remaining portion of the release paper 400, ensuring that the release paper 400 is stably clamped between the second part 1213 and the pressing part 1221, improving the laying efficiency of the release paper 400.

[0051] In one example, the pressure plate assembly 100 includes a first drive device. The first drive device connects to and drives the first pressing part 1211, the second pressing part 1221, and the pressure block 130, enabling them to move vertically relative to the base 110. The first drive device can be an electric linear actuator or a pneumatic cylinder. The first drive device is electrically connected to the upper pressure plate 121 and the lower pressure plate 122.

[0052] Specifically, when the release paper 400 needs to be cut, the first driving device pushes the upper pressure plate 121 and the lower pressure plate 122 downwards, allowing the release paper 400 held by the first pressing part 1211 and the second pressing part 1221 to be laid on the glass 300. Simultaneously, the pressure block 130 also moves with the lower pressure plate 122 to contact the cut release paper 400, ensuring stable pressure on the cut portion. Conversely, after cutting, the first driving device pushes the upper pressure plate 121 and the lower pressure plate 122 upwards, resetting the first pressing part 1211, the second pressing part 1221, and the pressure block 130 to prepare for the next paper-laying operation. The first driving device provides a stable power source for the plate 120 and the pressure block 130, enabling each component to complete its respective movement task. This not only improves the efficiency of paper-laying operations but also reduces the possibility of manual intervention, thereby lowering the risk of misoperation.

[0053] Furthermore, in another embodiment, the pressure plate assembly 100 also includes a second driving device. The second driving device is used to control the independent movement of the first pressing part 1211. That is, in addition to the overall up-and-down movement provided by the first driving device, the first pressing part 1211 can also achieve additional up-and-down movement relative to the second pressing part 1221 and the pressure block 130 through the second driving device. Specifically, during the paper laying process, since the release paper 400 to be laid is arranged between the first pressing part 1211 and the second pressing part 1221, relative movement needs to be generated between the first pressing part 1211 and the second pressing part 1221 to achieve the clamping and release of the release paper 400 to be laid. When the release paper 400 is laid, the first pressing part 1211, driven by the second driving device, will move upward relative to the second pressing part 1221, and the two will separate so that the release paper 400 can be pulled out from between the first pressing part 1211 and the second pressing part 1221. When the pull-out length of the release paper 400 reaches a preset value, the first pressing part 1211, driven by the second driving device, will move downward relative to the second pressing part 1221 until the first pressing part 1211 and the second pressing part 1221 abut against each other to jointly clamp the release paper 400. Then, the upper pressure plate 121 and the lower pressure plate 122 will move relative to the base 110 under the drive of the first driving device to drive the pressure block 130 to the designated position.

[0054] A second aspect of this utility model provides a paper laying machine 10, see reference. Figures 1 to 5 As shown, the paper laying machine 10 includes a cutting assembly 200 and a pressure plate assembly 100 as described in any of the above embodiments. The cutting assembly 200 is movably connected to the upper pressure plate 121 and can slide in the left-right direction relative to the upper pressure plate 121 and the lower pressure plate 122, thereby cutting the release paper 400 when the pressure plate assembly 100 is in the first position.

[0055] Specifically, when laying the release paper 400 using the paper laying machine 10, the release paper 400 needs to be pulled out from between the first pressing part 1211 and the second pressing part 1221 to cover the glass 300 to be laid. Then, the first pressing part 1211 is driven to move relative to the second pressing part 1221 by the second driving device, so that the first pressing part 1211 and the second pressing part 1221 can jointly clamp the release paper 400 to be laid and cut. Then, the first driving device drives the first pressing part 1211, the second pressing part 1221 and the pressure block 130 to move downward relative to the base 110, so that the pressure block 130 abuts against the previously stacked and cut release paper 400. Finally, the cutting assembly 200 moves in the left and right direction relative to the pressure plate assembly 100 to cut the release paper 400 to be laid.

[0056] The paper-laying machine 10 of this utility model uses the pressure block 130 to abut against the cut release paper 400 at the first position, increasing the distance between the release paper 400 to be cut and the release paper 400 that has been cut. This ensures that when the cutting component 200 cuts the release paper 400, the cutting component 200 will not come into contact with the previously cut release paper 400, thereby avoiding the release paper 400 being cut a second time and generating paper scraps, thereby improving the production efficiency of the glass 300.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
