Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laminators, and more specifically, to a heating bottom plate of a laminator. Background Art
[0002] A laminator is an important device required for manufacturing solar cell modules. It is a device that presses EVA, solar cell wafers, tempered glass, and back sheets into a rigid whole under high-temperature and vacuum conditions. The heating bottom plate is an essential component of the laminator and is used to heat-treat the modules. Sometimes, mid-hole fragments are generated after the modules are heated and laminated. This is mainly because when the modules are in a high-temperature state during lamination, the EVA melts and has strong fluidity. During the vacuum pumping process, the back sheet flows violently, and the solder tape on the front side of the cell wafer is more likely to apply force to the cell wafer, resulting in the cell wafer being damaged due to force; however, reducing the temperature will cause bubbles to be generated around the module due to insufficient temperature. Therefore, there is an urgent need for a heating bottom plate that can both reduce the temperature of the module at the mid-hole position during lamination but does not affect the temperature of other positions of the module. Summary of the Utility Model

[0029] Example, refer to Figures 1 - 2, which is an embodiment of the present utility model, proposes a heating bottom plate of a laminator for heating a component 11. A middle hole 12 is provided on the component 11, and it includes an upper heating plate 1, a lower heating plate 2, an upper high-temperature cloth 3, a lower high-temperature cloth 4, and a bottom high-temperature cloth 5. The lower heating plate 2 is located below the upper heating plate 1; the upper high-temperature cloth 3 is located between the upper heating plate 1 and the lower heating plate 2; the lower high-temperature cloth 4 is located between the lower heating plate 2 and the upper high-temperature cloth 3. A placement channel is formed between the upper high-temperature cloth 3 and the lower high-temperature cloth 4 for placing the component 11; the bottom high-temperature cloth 5 is provided between the lower high-temperature cloth 4 and the lower heating plate 2, and the middle holes 12 on the component 11 located in the placement channel are all directly above the bottom high-temperature cloth 5. By using the bottom high-temperature cloth 5 to isolate the temperature at the position of the middle hole 12 on the component 11, the temperature at the position of the middle hole 12 can be reduced, and at the same time, the temperature at other positions of the component 11 will not be affected. The probability of generating fragments at the middle hole 12 can be reduced, and at the same time, the generation of bubbles around the component 11 due to insufficient temperature can be avoided, thereby improving the product quality.
[0030] Further, the surface of the bottom high-temperature cloth 5 facing the lower high-temperature cloth 4 is a rough surface, which can increase the friction between the bottom high-temperature cloth 5 and the lower high-temperature cloth 4 and improve the isolation effect of the temperature at the position of the middle hole 12.
[0031] Further, as Figure 2 shown, the width of the bottom high-temperature cloth 5 is greater than the diameter of the middle hole 12, ensuring that the bottom high-temperature cloth 5 can effectively reduce the temperature at the position of the middle hole 12.
[0032] Further, as Figure 2 shown, the width of the bottom high-temperature cloth 5 is L, the diameter of the middle hole 12 is D, and the ratio of L to D is 1.5:1 - 3:1, and preferably 2.5:1. On the premise of ensuring that the bottom high-temperature cloth 5 can effectively reduce the temperature at the position of the middle hole 12, the width of the bottom high-temperature cloth 5 is reduced as much as possible, which can avoid the generation of bubbles around the component 11 due to insufficient temperature and can better ensure the product quality.
[0033] Further, as Figure 1 and Figure 2 shown, it further includes a transition plate 6. The transition plate 6 is arranged outside one end of the lower heating plate 2. One end of the bottom high-temperature cloth 5 is arranged on the transition plate 6, and the other end of the bottom high-temperature cloth 5 is arranged on the lower heating plate 2. The transition plate 6 does not contact the lower heating plate 2 and has a lower temperature. Fixing one end of the bottom high-temperature cloth 5 on the transition plate 6 can avoid discomfort of the operator caused by excessive temperature when disassembling and assembling the bottom high-temperature cloth 5.
[0034] Further, as Figure 2 shown, it further includes a high-temperature tape 7. The bottom high-temperature cloth 5 is adhered to the transition plate 6 by means of the high-temperature tape 7. Using the high-temperature tape 7 to adhere the bottom high-temperature cloth 5 to the transition plate 6, the connection is firm and reliable, the disassembly and assembly are convenient and fast, saving time and effort.
[0035] Further, as Figure 3 shown, it further includes a locking member 8, and the bottom high-temperature cloth 5 is arranged on the lower heating plate 2 by means of the locking member 8. The locking member 8 is a bolt or a screw. The bottom high-temperature cloth 5 is locked on the lower heating plate 2 by using the locking member 8, and the connection is firm and reliable, and the disassembly and assembly are convenient, fast, time-saving and labor-saving.
[0036] Further, as Figure 3 shown, it further includes a fixing column 9. The bottom high-temperature cloth 5 is clamped between the fixing column 9 and the lower heating plate 2. One end of the locking member 8 passes through the fixing column 9 and the bottom high-temperature cloth 5 and then is connected to the lower heating plate 2, and the other end of the locking member 8 is located outside the fixing column 9. The bottom high-temperature cloth 5 is pressed against the lower heating plate 2 by using the fixing column 9, and then the fixing column 9 and the bottom high-temperature cloth 5 are fixed on the lower heating plate 2 by using the locking member 8, which can increase the stress area of the bottom high-temperature cloth 5 and make the connection more firm and reliable.
[0037] Further, the number of the locking members 8 is at least two, and all the locking members 8 are arranged along the length direction of the fixing column 9. The multiple locking members 8 act together to make the connection between the fixing column 9, the bottom high-temperature cloth 5 and the lower heating plate 2 more firm and reliable.
[0038] Further, as Figure 1 shown, it further includes a silica gel plate 10. The silica gel plate 10 is arranged at the bottom of the upper heating plate 1. The upper high-temperature cloth 3 is located below the silica gel plate 10, and the bottom surface of the silica gel plate 10 is an arc surface protruding downward in the middle. The silica gel plate 10 can make the heat generated by the upper heating plate 1 radiate more evenly to the surroundings, so that the component 11 is heated more evenly.
