Description

Technical Field

[0001] The utility model relates to the technical field of preparation of film-covered battery strings, in particular to a battery string heating and flexible pressing device. Background Art

[0002] When preparing a film-covered battery string, an infrared light heating member heats battery cells in the to-be-welded film-covered battery string through infrared light, so that the adhesive films on the opposite sides thereof are melted, and a solder strip is pasted on the front and back surfaces of the battery cells through the adhesive film to fix the solder strip group relative to the battery cells. At the same time, the adhesive film is also liable to adhere to the conveying belt when heated, and when the film-covered battery string is separated from the belt conveying channel, the adhesive film is liable to be lifted up, resulting in local bulging.

[0003] In related technologies, through secondary heating and pressing, the area where the adhesive film is lifted up is pasted on the battery cell again, but the pressing contacts on both sides of the adhesive film facing the conveying belt are all rigid contacts. As Figure 1 shown, a part of the adhesive film near the solder strip group is not completely attached, resulting in a gap. When the produced photovoltaic module is subjected to EL detection after lamination, multiple shadows appear around the solder strip group, thereby reducing the qualified rate.

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] As Figures 2 to 4 shown, the present application discloses a battery string heating and flexible pressing device. The disclosed battery string heating and flexible pressing device includes a conveying mechanism 100, a first heating element 200, a support deformation component 300, and a pressing tool 400. Among them, the first heating element 200 can be an infrared heating lamp tube, an infrared heating LED lamp bead, etc., and the present application does not make any restrictions on this.

[0027] Specifically, the press tool 400 is disposed above the conveying mechanism 100 in a liftable manner. The support deformation assembly 300 is embedded in the conveying mechanism 100. The support surface of the support deformation assembly 300 is flush with the conveying surface of the conveying mechanism 100. The press tool 400 is opposite to the support deformation assembly 300. The conveying mechanism 100 can drive the battery string to move. The support deformation assembly 300 includes a flexible deformation plate 320 covering its top. The first heating element 200 is used to heat a part of the battery string located on the support deformation assembly 300. The press tool 400 is used to press the part of the battery string after being heated by the first heating element 200.

[0028] During the use of the battery string heating and flexible pressing device, after the battery string undergoes the first welding process and all the press tools pressing itself are recycled, the conveying mechanism 100 carries and drives the battery string to move step by step. When a part of the battery string moves onto the support deformation assembly 300, the first heating element 200 heats the part of the battery string. When the adhesive films on both sides of the battery cells in the part of the battery string are heated to a molten state, the press tool 400 descends to press the part of the battery string after being heated by the first heating element 200. The press tool 400 and the support deformation assembly 300 are in extrusion cooperation. The support deformation assembly 300 deforms under pressure, so that the part of the battery string facing one side of the support deformation assembly 300 is flexibly wrapped by the support deformation assembly 300 to increase the contact area and is extruded in the reverse direction, so that the adhesive film around the solder strip in the part of the battery string facing one side of the support deformation assembly 300 can be completely adhered. This is beneficial for reducing the shadows around the solder strip group during the EL detection after lamination of the photovoltaic module produced by this battery string, thereby improving the qualification rate.

[0029] In the embodiment of the present application, the disclosed battery string heating and flexible pressing device may further include a gas blowing assembly. Specifically, the gas blowing assembly is disposed in the conveying mechanism 100. The gas blowing assembly is located below the support deformation assembly 300. The gas blowing assembly can blow out gas along the embedding gap between the support deformation assembly 300 and the conveying mechanism 100, so that when the battery string passes through this gap, it will not contact the support deformation assembly 300 and cause damage to the battery cells in the battery string, ensuring that the battery string can pass through the support deformation assembly 300 smoothly.

[0030] In a further technical solution, the gas blowing assembly can be disposed on the conveying mechanism 100. The support deformation assembly 300 is provided with a gas path and a plurality of air outlet holes disposed on the support end of the support deformation assembly 300 and communicated with the gas path. The gas blowing assembly is communicated with the gas path. By blowing air through the gas blowing assembly, passing through the gas path, and then discharging from the plurality of air outlet holes, it is beneficial that, except when the press tool 400 descends to press the part of the battery string, at least part of the battery string is easily suspended and passes through when passing through the support deformation assembly 300, avoiding abrasion.

[0031] In the embodiment of the present application, the support deformation assembly 300 may include a base 310 and a flexible deformation plate 320. Specifically, the base 310 is embedded in the conveying mechanism 100, and the flexible deformation plate 320 covers the base 310.

[0032] Of course, the flexible deformation plate 320 can be a silica gel plate, a sponge plate, a TPE plate, etc., and the present application does not make any restrictions on this.

[0033] In the embodiment of the present application, a second heating element 500 may be provided below the support deformation assembly 300 of the conveying mechanism 100. When a part of the battery string moves onto the support deformation assembly 300, the second heating element 500 is in an on state, and heat can be sequentially transferred to the support deformation assembly 300 and the part of the battery string, so that the adhesive films on both sides of the battery cells in the part of the battery string can be heated to a molten state. The press tool 400 descends to press the part of the battery string, and the press tool 400 and the support deformation assembly 300 are in extrusion cooperation. The support deformation assembly 300 deforms under pressure, so that the part of the battery string facing one side of the support deformation assembly 300 is flexibly wrapped by the support deformation assembly 300 and is reversely extruded, so that the adhesive film around the solder tape in the part of the battery string facing one side of the support deformation assembly 300 can be completely adhered.

[0034] In addition, the second heating element 500 can be a heating rod, an electric soldering iron, etc., and the present application does not make any restrictions on this.

[0035] In the embodiment of the present application, an air-blowing support platform 600 may be provided on the conveying mechanism 100 along its conveying direction and adjacent to the support deformation assembly 300. When approaching the support deformation assembly 300, the blowing action of the air-blowing support platform 600 can make the part of the battery string move upward slightly, so as to avoid damage to the battery cells in the battery string caused by the part of the battery string contacting the support deformation assembly 300.

[0036] In the embodiment of the present application, the base 310 may be provided with a plurality of protrusions, and the flexible deformation plate 320 may be provided with a plurality of grooves. Specifically, the plurality of protrusions and the plurality of grooves are engaged with each other. The flexible deformation plate 320 and the base 310 are engaged and cooperated through the plurality of protrusions and the plurality of grooves.

[0037] In the embodiment of the present application, a flexible deformation layer may be covered on the pressing surface of the press tool 400. So that when the press tool 400 and the support deformation assembly 300 are in extrusion cooperation, the flexible deformation layer presses the part of the battery string heated by the first heating element 200, and the part of the battery string facing the press tool 400 can be flexibly wrapped and extruded by the flexible deformation layer.

[0038] In an alternative solution, the first heating element 200 can be arranged on the pressing tool 400. The pressing tool 400 can be a light-transmitting pressing tool. The first heating element 200 can be an infrared light heating element. The first heating element 200 can move up and down with the pressing tool 400, so that the distance between the first heating element 200 and the battery string is convenient to adjust, thereby increasing the irradiation area of the infrared light heating element and a part of the battery string, and also facilitating the integrated design of the structure.

[0039] In another alternative solution, the first heating element 200 can be located above the conveying mechanism 100. The first heating element 200 is fixedly arranged, so as to avoid an interaction area when the first heating element 200 moves and the pressing tool 400 moves up and down, thereby avoiding movement interference between the two.

[0040] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
