Description

Technical Field

[0001] The utility model belongs to the technical field of laser scribing, and in particular relates to a multi-channel laser automatic scribing production line. Background Art

[0002] Laser scribing equipment is mainly used in the manufacturing process of thin-film solar cells and crystalline silicon solar cells. The product is transmitted by the CV wheel and stays on the laser scribing platform. The laser scribes the product to complete the processing of the product. After the scribing, it is transmitted to the next process through the CV wheel. However, as the size of the product increases, the gravity of the product itself increases, and the span of the corresponding laser scribing equipment increases. During the laser scribing process, the middle part sinks due to the increase in span. The product process requires that the flatness of the laser scribing platform be less than 0.1mm, while the actual measured value is 0.5mm, which is much larger than the process requirement. Therefore, the flatness of the product during scribing cannot be guaranteed. Utility Model Content

[0003] The utility model aims to provide a multi-channel laser automatic scribing production line to solve the technical problem that the existing laser scribing process cannot meet the process requirements of products with larger sizes.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A multi-channel laser automatic marking production line includes a laser marking platform, the laser marking platform includes two mounting side plates, and a plurality of roller shaft groups are installed between the two mounting side plates;

[0006] Each roller set includes a support bar and two rollers. Both ends of the rollers are rotatably mounted on two mounting side plates through bearings. Several CV wheels are arranged on the rollers. Both ends of the support bar are fixed on the two mounting side plates, and the support bar is located between the two rollers. Three bearing seats are arranged on each side of the support bar. One roller is rotatably mounted on the three bearing seats on one side of the support bar through three bearings, and the other roller is rotatably mounted on the three bearing seats on the other side of the support bar through three bearings.

[0007] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model installs a support bar between two adjacent rollers, so that the three are connected as one, ensuring the flatness of the laser scribing platform, so that large-area products can be generated, ensuring the processing quality of the products while also improving the output efficiency of the products, thereby further optimizing the laser scribing process, improving the manufacturing process of solar cells, and providing the society with better solar cell products.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] The present invention is further described in detail below in conjunction with the embodiments.

[0015] like Figure 1-4 As shown, a specific embodiment of a multi-channel laser automatic scribing production line provided by the utility model:

[0016] A multi-channel laser automatic marking production line includes a laser marking platform A, wherein the laser marking platform A includes two mounting side plates 1, and a plurality of roller shaft groups are installed between the two mounting side plates 1;

[0017] Each roller set includes a support bar 2 and two rollers 3. Both ends of the rollers 3 are rotatably mounted on two mounting side plates 1 through bearings. A plurality of CV wheels 4 are arranged on the rollers 3. Both ends of the support bar 2 are fixed on the two mounting side plates 1, and the support bar 2 is located between the two rollers 3. Three bearing seats 5 are arranged on both sides of the support bar 2, two of which are close to one end of the support bar 2, two of which are close to the middle of the support bar 2, and the other two of which are close to the other end of the support bar 2.

[0018] One of the rollers 3 is rotatably mounted on three bearing seats 5 on one side of the support bar 2 via three bearings, and the other roller 3 is rotatably mounted on three bearing seats 5 on the other side of the support bar 2 via three bearings.

[0019] The multi-channel laser automatic marking production line of this embodiment installs a support bar 2 between two rollers 3, so that the support bar 2 and the two adjacent rollers 3 form a whole, preventing the middle part of the roller 3 that is too long from sinking after carrying the product, thereby ensuring the flatness of the laser marking platform A.

[0020] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
