Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of material connection, and in particular to a UV fixing device for a welding strip and a battery cell. Background Art
[0002] Material connection technology refers to the process of combining two or more materials using specific physical or chemical means to form a composite structure with specific properties and functions. In this technology, the bonding of the soldering ribbon and the battery cell is achieved through ultraviolet curing adhesive (UV glue). During the curing process, the UV glue can quickly change from liquid to solid after being irradiated by ultraviolet rays, thereby ensuring a stable bonding effect between the materials.
[0003] A Chinese patent discloses a wire mesh elastic anti-sticking pressure strip device and a battery cell string welding machine (authorization announcement number CN207753034U). This patented technology no longer uses the wire mesh to directly contact the welding strip to apply pressure, but uses the tension of the wire mesh to provide the downward pressure of the pressing needle, and the pressing needle presses against the welding strip to press the welding strip onto the battery panel. In view of the above and existing related technologies, the inventor believes that there are often the following defects: when the existing welding strip and the battery cell are fixed, most of them use the method of pressing the welding strip to the battery board by pressing the pressing needle, but the method of pressing the pressing needle is more likely to cause a cold weld due to the inaccurate welding point between the welding strip and the battery panel, and the pressure brought by the pressing needle to the battery panel is relatively large. Once any of the pressing needles has elasticity problems due to the tension of the wire mesh, it is easy to press the battery panel into a hidden crack, resulting in quality problems for the entire battery string. Summary of the invention
[0004] The technical problem to be solved by the present invention is that in the prior art, solder strips and solar panels are prone to cold soldering, and the method of controlling the pressure of the pressing needle by adjusting the tension of the wire mesh will cause uneven pressure and difficulty in control, which can easily cause hidden cracks in the solar panel. For this reason, we propose a UV fixing device for solder strips and solar cells.

[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0020] Reference Figure 1 - Figure 4As shown, the present invention provides a technical solution: a soldering ribbon and battery cell UV fixing device, comprising a clamping mechanism 1, comprising a clamping mechanism 1 and a UV curing mechanism 2, characterized in that: an elastic anti-adhesion pressure strip 3 is arranged at the bottom end of the clamping mechanism 1, a battery cell body 4 is placed at the bottom end of the elastic anti-adhesion pressure strip 3, a soldering ribbon body 5 is installed on the surface of the battery cell body 4, the interior of the clamping mechanism 1 comprises a mounting bracket 10, a downward pressing driving mechanism 11 and a pressing plate mechanism 12, the mounting bracket 10 is installed at the bottom end of the clamping mechanism 1, the downward pressing driving mechanism 11 is installed at the top end of the mounting bracket 10, and the pressing mechanism 12 is installed at the bottom end of the clamping mechanism 1. The plate mechanism 12 is installed at the top of the downward pressure driving mechanism 11. The downward pressure driving mechanism 11 includes a servo motor 110, a motor support 111, a screw body 112, a screw support seat 113, a guide device 114, a coupling 115 and a limit sensor 116. The servo motor 110 is installed at the bottom of the downward pressure driving mechanism 11. The motor support 111 is installed at the top of the servo motor 110. The limit sensor 116 is installed on the surface of the motor support 111. The guide device 114 is installed on the surface of the mounting bracket 10. The number of the guide devices 114 is two. The coupling 11 5 is installed inside the motor support 111, the screw support seat 113 is installed on the top of the coupling 115, the screw body 112 is installed on the top of the screw support seat 113, the interior of the pressing plate mechanism 12 includes a light-transmitting pressing plate 120, an elastic anti-sticking pressure strip 121, a pressing plate frame 122 and an adjustment fixing frame 123, the adjustment fixing frame 123 is installed at the top of the pressing plate mechanism 12, the pressing plate frame 122 is installed at the front end of the pressing plate mechanism 12, the light-transmitting pressing plate 120 is installed at the bottom end of the pressing plate mechanism 12, the pressing plate frame 122 and the light-transmitting pressing plate 120 are fixed by threads, and the pressing plate frame 122 The adjustment fixing frame 123 is fixed with threads. When the soldering tape body 5 and the battery cell body 4 with UV glue are conveyed to the specified position, the clamping mechanism 1 controls the transparent pressing plate 120 to press the soldering tape body 5 and the battery cell body 4 flatly, so that each soldering tape body 5 is completely in contact with the UV glue point position on the corresponding battery cell body 4. Compared with the prior art that uses the elastic anti-sticking strip 3 to press down, it is less likely to damage the battery cell body 4, and the UV glue point position on the battery cell body 4 can be completely and tightly contacted with the soldering tape body 5, thereby ensuring the uniform distribution and curing effect of the UV glue.
[0021] Reference Figure 5 As shown, in the present embodiment: a fixing groove is opened at the bottom end of the light-transmitting pressing plate 120, and an elastic anti-sticking strip 121 is installed inside the fixing groove. Through the setting of the elastic anti-sticking strip 121, when the light-transmitting pressing plate 120 presses the solder strip body 5 and the battery cell body 4, due to the elastic effect of the elastic anti-sticking strip 121, it can effectively prevent the UV glue from overflowing or sticking to the pressing plate during the pressing process, thereby pressing the solder strip and the battery cell tightly and more flatly, and at the same time it is not easy to cause hidden cracks in the battery cell.
[0022] Reference Figure 5 As shown, in this embodiment: the UV curing mechanism 2 includes a main body support 20, a UV light source 21, a height adjustment device 22, a locking device 23 and a sliding device 24, the main body support 20 is installed inside the UV curing mechanism 2, the surface of the UV curing mechanism 2 is installed with a locking device 23, the UV light source 21 is installed at the bottom of the UV curing mechanism 2, the number of height adjustment devices 22 is four and all are installed at the top of the UV light source 21, the sliding device 24 is installed on both sides of the UV light source 21, when the UV curing mechanism 2 is working, the distance between the UV light source 21 and the welding strip body 5 and the battery cell body 4 can be accurately controlled by the height adjustment device 22, to ensure that the UV light is evenly irradiated on the UV glue point, so as to achieve the best curing effect, the locking device 23 is used to fix the position of the UV curing mechanism 2 to prevent movement during the UV curing process, thereby ensuring the stability of the curing process, and the sliding device 24 allows the UV curing mechanism 2 to move within a certain range to adapt to battery cell bodies 4 of different sizes, thereby improving the applicability and flexibility of the device.
[0023] Reference Figure 1 and Figure 2 As shown, in this embodiment: the soldering strip body 5, the battery cell body 4, the clamping mechanism (1) and the UV curing mechanism 2 are arranged at the same station. Such an arrangement can ensure that during the welding process, the relative position between the battery cell body 4 and the soldering strip body 5 remains stable. Such stability can effectively prevent any position deviation in the welding fixing link, thereby ensuring the reliability of the welding quality.
[0024] Step 1: Standby preparation
[0025] In the standby state, the downward pressing driving mechanism 11 in the clamping mechanism 1 works to lift the pressing plate mechanism 12 to a high position. This step ensures that in the initial state, the pressing plate mechanism 12 is in a position that does not affect the conveying of the welding strip body 5 and the battery cell body 4, and is ready for subsequent material conveying and processing.
[0026] Step 2: Material conveying and compaction
[0027] When the solder strip body 5 and the battery cell body 4 with UV glue are conveyed to the bottom of the pressing plate mechanism 12, the downward pressing drive mechanism 11 starts to drive the pressing plate mechanism 12 to move downward until it reaches the pressing position. During this process, the elastic pressure strip 121 in the pressing plate mechanism 12 plays a key role. It can tightly press all the solder strip bodies 5 and the battery cell body 4, and through its elastic characteristics, it ensures that each solder strip body 5 is in full contact with the UV glue point position on its corresponding battery cell body 4, providing good contact conditions for subsequent UV glue curing and bonding.
[0028] Step 3: UV glue curing
[0029] After the soldering strip body 5 and the battery cell body 4 are pressed together, the UV light source 21 is turned on and irradiates them in the pressed state. The irradiation of UV light causes the UV glue on the battery cell body 4 to undergo a curing reaction, thereby firmly bonding the soldering strip body 5 and the battery cell body 4 together. In this process, the irradiation time of UV light needs to be precisely controlled to ensure that the UV glue can be fully cured to achieve the ideal bonding strength.
[0030] Step 4: Completion and Reset
[0031] When the set UV light irradiation time is reached, the UV light source 21 is turned off and the irradiation of the solder strip body 5 and the battery cell body 4 is stopped. At the same time, the downward drive mechanism 11 drives the clamping mechanism 1 to return to the high-position standby state, so that the entire device is restored to the initial standby preparation state, so as to carry out the next round of bonding processing operations of the solder strip body 5 and the battery cell body 4.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
