[0002] Photovoltaic cells are the core components of photovoltaic power generation systems, and their quality directly impacts the performance and lifespan of photovoltaic modules. To improve the durability and protection of photovoltaic cells, the edges of the cells are typically hemmed to prevent cracking, peeling, oxidation, and other issues. Hemming methods include dispensing, roller-type, and immersion methods.
[0003] After the existing immersion hemming machine has hemmed the battery cell, it is necessary to control the battery cell to rise between two sets of UV lamps for UV curing, and the light sources of the two sets of UV lamps are usually facing both sides of the battery cell, and the light emitted will irradiate the surface of the hemming glue liquid in the glue box. In order to prevent the light source of the UV lamp from curing the hemming glue on the surface of the glue box and affecting the subsequent hemming effect, after the battery cell is separated from the glue surface, an accordion cover is usually set to shield the surface of the hemming glue in the glue box, and then UV curing is performed on the surface of the battery cell.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example
[0019] like Figure 1-Figure 4As shown, a photovoltaic cell edge wrapping machine includes a cell placing mechanism, a glue box 13 for dipping the cell body 7 on the cell placing mechanism into glue, and also includes: a UV curing component, the UV curing component includes a first curing module and a second curing module, the first curing module includes a first lamp body 16, a light strip 22 installed on the outer wall of the first lamp body 16, a lower adjustment plate 23 and an upper adjustment plate 24 installed on the outer wall of the first lamp body 16 and arranged on the same side as the light strip 22, the upper adjustment plate 24 is superimposed on the outer wall of the lower adjustment plate 23 for adjusting the light output area of the light strip 22, and an adjustment mechanism installed on the outer wall of the first lamp body 16 for adjusting the light output angle of the light strip 22.
[0020] After the battery cell body 7 is transported to the top of the glue box 13 by the sheet placing mechanism, it is wrapped with edge glue on the surface of the glue box 13, and then transported to the first curing module and the second curing module by the sheet placing mechanism for UV curing. Taking the first curing module as an example, by adjusting the distance between the lower adjustment plate 23 and the upper adjustment plate 24 on the outer wall of the first lamp body 16, the light output area of the light strip 22 is adjusted, which is conducive to irradiating the light emitted by the light strip 22 on the edge of the battery cell body 7, and preventing the light output area of the light strip 22 from being too large and irradiating the edge glue surface inside the glue box 13. By setting an adjustment mechanism, the light output angle of the light strip 22 irradiated on the surface of the battery cell body 1 can be adjusted. The adjustment mechanism is used in conjunction with the first curing module and the second curing module to further prevent the light source emitted by the light strip 22 from irradiating the edge glue surface inside the glue box 13, and prevent the edge glue surface inside the glue box 13 from being cured, affecting the subsequent edge binding effect.
[0021] The first screw threaded hole 25 is provided on the bottom surface of the first adjusting plate 16 so that the first adjusting plate 16 and the upper adjusting plate 24 can adjust the distance between the two concave surfaces along the direction of the slot, thereby adjusting the light output area of the lamp strip 22. The lower adjusting plate 23 and the upper adjusting plate 24 are fixedly connected to the outer wall of the first lamp body 16 by a first bolt. The first bolt passes through the two U-shaped grooves 25 of the lower adjusting plate 23 and the upper adjusting plate 24 and is threadedly connected to the inner wall of the first screw threaded hole. After the distance between the lower adjusting plate 23 and the upper adjusting plate 24 is adjusted, the lower adjusting plate 23 and the upper adjusting plate 24 are fixed to the outer wall of the first lamp body 16 by screwing the first bolt into the first screw threaded hole.
[0022] Specifically, the deflection adjustment mechanism includes a support plate 14 fixedly connected to the top of the plastic box 13, a bent plate 18 fixedly connected to the outer wall of the first lamp body 16, an arc groove 19 is provided on the outer wall of the support plate 14, a second bolt 20 is slidably connected to the inner wall of the arc groove 19, a second threaded hole is provided on the outer wall of the bent plate 18 away from the first lamp body 16, the second bolt 20 passes through the arc groove 19 and is threadedly connected to the inner wall of the second threaded hole, a handle 21 is fixedly installed on the outer wall of the first lamp body 16, and the first lamp body 16 is adjusted by holding the handle 21. The deflection angle of the body 16 is adjusted to adjust the light output angle of the lamp strip 22. When the first lamp body 16 rotates, the bending plate 18 is driven to deflect synchronously, thereby driving the second bolt 20 to slide in the arc groove 19. After adjusting the light output angle of the lamp strip 22, the second bolt 20 is tightened to the second threaded hole to position the bending plate 18, thereby realizing the deflection adjustment function of the lamp strip 22, preventing the light source emitted by the lamp strip 22 from irradiating the edging glue surface in the glue box 13 and solidifying the edging glue surface inside the glue box 13, affecting the subsequent edging effect.
[0023] The second curing module includes a second lamp body 17. The second curing module has the same structure as the first curing module. The light strips 22 of the first curing module and the second curing module are both arranged above the glue box 13 and heat and cure the two sides of the battery cell body 7 after being dipped in glue, thereby improving the UV curing effect. Example
[0024] like Figure 1-Figure 2 The film placing mechanism shown includes a flipping mechanism, a Z-axis driving component 9 and a positioning mechanism. The flipping mechanism includes a vertically arranged back plate 1, a U-shaped plate 4 slidably connected to the outer wall of the back plate 1 close to the plastic box 13, a flipping shaft 5 rotatably connected to the inner wall of the U-shaped plate 4, and a DD motor 6 fixedly connected to the top of the flipping shaft 5. The top of the DD motor 6 is fixedly connected to a suction cup for adsorbing the battery cell body 7. The outer wall of the back plate 1 is provided with a solenoid valve 3 connected to the suction cup. It also includes a flipping motor 8 arranged on the outer wall of the U-shaped plate 4 for driving the flipping shaft 5 to rotate. The Z-axis driving component 9 is connected to the outer wall of the back plate 1 and drives the U-shaped plate 4 to move up and down along the outer wall of the back plate 1.
[0025] The alignment mechanism includes two groups of vertically arranged backlight sources 10, and the bottom of the backlight source 10 is fixedly connected to a connecting plate 2, which is arranged between the back plate 1 and the plastic box 13. The two groups of backlight sources 10 are respectively arranged on both sides of the flip axis 5 for irradiating the back side of the battery cell body 7 in the vertical state after flipping. The alignment mechanism also includes an alignment camera 11 arranged facing the light source direction of the backlight source 10.
[0026] In the initial state, the DD motor and the suction cup are both in a vertical state. The battery cell body 7 is placed horizontally above the suction cup, the solenoid valve 3 is connected to an external air pump, the suction cup adsorbs the battery cell body 7, and the flip motor 8 is started. The flip motor 8 drives the flip axis 5 to deflect 90 degrees, thereby driving the DD motor 6 and the suction cup to flip synchronously, and then flipping the battery cell body 7 to a vertical state, and the battery cell body 7 is directly above the glue box 13. At this time, the backlight source 10 illuminates the back of the battery cell body 7, and the alignment camera 11 takes a picture of the battery cell body for alignment, and then sends the alignment result to the DD motor 6. The DD motor 6 corrects the battery cell body 7 according to the alignment result to ensure that the edge of the battery cell body 7 is relatively level with the glue surface of the glue groove 13, thereby improving the edge wrapping accuracy. Then, the Z-axis drive component 9 is started, and the U-shaped plate 4 is driven by the Z-axis drive component 9 to move downward along the outer wall of the back plate 1, thereby driving the flip axis 5, the DD motor 6, and the suction cup to move synchronously, and then the battery cell body 7 is transported to the inside of the glue box 13 for edge wrapping.
[0027] After the battery cell body 7 is edge-wrapped, the Z-axis drive 9 drives the battery cell body 7 to rise between the first curing module and the second curing module for UV curing, and then the DD motor drives the suction cup and the battery cell body 7 to rotate, repeating the above correction steps for the battery cell body 7, and then the Z-axis drive 9 drives the battery cell body 7 to descend, completing the edge-wrapping work of all edges of the battery cell body 7.
[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
