Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic manufacturing, and more particularly, to a screen cleaning device. BACKGROUND

[0002] In the processing of photovoltaic modules, it is necessary to connect the solder strips and the cell pieces into cell strings, and the reliable connection between the solder strips and the cell pieces is one of the key steps to ensure the performance and quality of the photovoltaic modules. In order to achieve this goal, a glue applying device is usually used to apply glue on the solder strips after the cell strings are formed, or to apply glue on the cell pieces before the cell strings are formed. The glue applying device mainly consists of a screen and a doctor blade assembly, wherein the screen is provided with an array of screen holes for carrying glue, and the doctor blade assembly is responsible for scraping the glue on the screen through the screen holes to the solder strips or to the cell pieces. After the glue is cured, the solder strips and the cell pieces are bonded.

[0003] However, in actual production, after the screen is used for a long time, glue residues and other impurities are easy to block the screen holes, resulting in failure to apply glue normally, and thus affecting the connection effect of the solder strips and the cell pieces, and even reducing the performance of the entire photovoltaic module.

[0004] At present, in order to solve this problem, the method of manually cleaning the screen regularly is mostly adopted. However, the manual cleaning is low in efficiency and time-consuming, and cannot meet the strict requirements of modern photovoltaic module manufacturing process for efficient and clean production.

[0218] The position layout of each mechanism in the present application can be determined according to the actual needs of the work site. As one of the embodiments, as shown in Figure 1 The feeding mechanism 1, the wiping mechanism 2, the detection mechanism 3, and the two material collecting mechanisms 4 are arranged in sequence along the first direction, the conveying track 51 extends along the first direction, and the conveying track 51 is arranged above the feeding mechanism 1, the wiping mechanism 2, the detection mechanism 3, and the two material collecting mechanisms 4. The transfer assembly 52 is two, which are respectively marked as the left transfer assembly 52 and the right transfer assembly 52. The left transfer assembly 52 and the right transfer assembly 52 are respectively hung below the conveying track 51. The specific working process is summarized as follows:

[0219] The first material frame 11 is pulled out to the replenishment position, and the screen plate 100 to be cleaned is manually stacked in the first material frame 11 in sequence, after the replenishment is completed, the first material frame 11 is pushed back to the original position, and the first driving member 122 in the feeding mechanism 1 drives the first supporting plate 1231 to rise, the screen plate 100 in the first material frame 11 is lifted by the first supporting plate 1231, and stops until the first screen plate 100 on the top layer reaches the first specified height.

[0220] The left side transfer assembly 52 is controlled to move along the conveying track 51 to the upper side of the first material frame 11, the lifting driving part 522 in the left side transfer assembly 52 drives the pickup part 523 to descend, so that the pickup part 523 reaches the first specified height where the first screen plate 100 on the top layer is located, the first clamping jaw 5231 and the second clamping jaw 5232 of the pickup part 523 are controlled to approach each other to clamp the first screen plate 100 on the top layer, after the first screen plate 100 on the top layer is clamped by the pickup part 523, the pickup part 523 is lifted by the lifting driving part 522, and the left side transfer assembly 52 is controlled to move horizontally to the upper side of the wiping mechanism 2.

[0221] The left side transfer assembly 52 places the picked first screen plate 100 on the second supporting frame 21 of the wiping mechanism 2, and controls the brush roller 232 to rotate and move horizontally to clean the first screen plate 100 by the brush roller 232. The brush roller 232 can be controlled to move horizontally in one direction once, or move in two directions twice, or repeatedly move multiple times for cleaning.

[0222] After the left side transfer assembly 52 places the picked screen plate 100 on the second supporting frame 21 of the wiping mechanism 2, the left side transfer assembly 52 returns to the upper side of the feeding mechanism 1 again, and the first driving member 122 in the feeding mechanism 1 drives the first supporting plate 1231 to rise by the height of a screen plate 100, so that the second screen plate 100 on the top layer also rises to the first specified height and waits for feeding.

[0223] After the left side transfer assembly 52 moves to the feeding mechanism 1, the second screen plate 100 of the feeding mechanism 1 is continuously carried, and the first screen plate 100 is carried away after being cleaned in the wiping mechanism 2, and the left side transfer assembly 52 places the second screen plate 100 in the wiping mechanism 2 for cleaning.

[0224] After the first screen plate 100 is cleaned in the wiping mechanism 2, the first screen plate 100 is carried to the detection mechanism 3 by the right side transfer assembly 52 first, if the cleanliness of the first screen plate 100 meets the standard, the first screen plate 100 is placed in the left side material collecting mechanism 4, and the left side material collecting mechanism 4 is used to specially contain the screen plate 100 whose cleanliness meets the standard; if the cleanliness of the first screen plate 100 does not meet the standard, the first screen plate 100 is placed in the right side material collecting mechanism 4, and the right side material collecting mechanism 4 is used to specially contain the screen plate 100 whose cleanliness does not meet the standard.

[0225] The second screen 100, after being wiped by the wiping mechanism 2, is first carried by the right side moving and carrying assembly 52 to the detecting mechanism 3 for detection, and then placed into the left or right side material receiving mechanism 4 according to the detection result.

[0226] The cleaning process of the subsequent screen 100 is as above, and will not be described one by one.

[0227] In addition, it should be noted that, since the residual glue that needs to be cleaned of the screen 100 mainly concentrates on the glue containing side of the screen 100 and the screen holes, when the screen 100 is stacked in the first material frame 11, the glue containing side of the screen 100 faces downward, so that the glue containing side of the screen 100 carried to the wiping mechanism 2 and the detecting mechanism 3 all faces downward, so that the brush roller 232 in the wiping mechanism 2 contacts the glue containing side of the screen 100, and the detecting mechanism 3 detects whether the glue containing side of the screen 100 is cleaned.
