Description

Technical Field

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

[0002] During the processing of photovoltaic modules, the soldering tape and the battery cells need to be connected in series to form a battery string. To ensure that the soldering tape and the battery string are reliably connected, a glue-applying device is usually used to apply glue to the soldering tape after the battery string is formed, or a glue-applying device is used to apply glue to the battery cell before the battery string is formed. The glue-applying device includes a screen and a scraper assembly. The screen has mesh holes arranged in an array. The screen is used to hold glue. The scraper assembly can scrape the glue on the screen from the mesh holes to the soldering tape. After the glue is cured, the soldering tape and the battery cell are reliably bonded. After the screen is used for a long time, the glue or other impurities on the screen are easy to clog the mesh holes. To ensure normal glue application, the screen is usually cleaned manually on a regular basis, but the efficiency of manual cleaning is low and cannot meet the needs of efficient production. Summary of the invention

[0010] By setting a feeding mechanism in the screen cleaning device for automatic feeding, manual intervention can be reduced and production efficiency can be improved. When cleaning the screen, the screen to be cleaned at the feeding mechanism can be first transferred to the cleaning mechanism by the transfer mechanism for cleaning, so as to remove glue or other impurities on the screen surface and inside the mesh. After cleaning, the cleaned screen is transferred to the drying mechanism for drying by the transfer mechanism to reduce moisture residue on the screen surface. After drying, the dried screen is transferred to the receiving mechanism for storage by the transfer mechanism.

When all the screens in the first material frame are taken out by the transfer mechanism, the first material frame can be moved out manually by the operator or automatically by the second driving member to avoid the transfer mechanism for refilling. At the refilling position, the next batch of screens to be cleaned can be placed in the first material frame manually or by a robot, thereby realizing refilling of the first material frame.

The design of the screen placement rack 71 can ensure that the screen 100 remains stable during the detection process, avoiding detection errors caused by shaking, and through stable support, the reliability and consistency of detection can be improved.

[0257] Optional, continue to Figure 13-14 , the third mounting frame 7121 is installed on the supporting platform 74.

Good lighting conditions can enable the camera to capture the details of the surface of screen 100 more clearly, reducing misjudgment and missed detection.

[0266] The location layout of each mechanism in this application can be determined according to the actual needs of the work site. As one embodiment, Figure 1 As shown, the feeding mechanism 1, the cleaning mechanism 6, the washing mechanism 2, the drying mechanism 3, the detection mechanism 7 and the two receiving mechanisms 4 are arranged in sequence along the first direction, and the conveying track 51 extends along the first direction, and the conveying track 51 is arranged above the feeding mechanism 1, the cleaning mechanism 6, the washing mechanism 2, the drying mechanism 3, the detection mechanism 7 and the two receiving mechanisms 4. There are two transfer components 52, which are marked as the left transfer component 52 and the right transfer component 52, respectively. The left transfer component 52 and the right transfer component 52 are respectively suspended below the conveying track 51. The specific work flow is summarized as follows:

[0267] The first material frame 11 is pulled out to the material replenishing position, and the screens 100 to be cleaned are manually stacked in sequence into the first material frame 11. After the material replenishing is completed, the first material frame 11 is pushed back to its original position, and the first driving member 122 in the feeding mechanism 1 drives the first support plate 1231 to rise, and the first support plate 1231 is used to support the screens 100 in the first material frame 11 to move upward until the first screen 100 on the top layer reaches the first specified height and stops.

[0268] The left side transfer component 52 is controlled to move along the conveying track 51 to the top of the first material frame 11, and the lifting drive unit 522 in the left side transfer component 52 drives the picking unit 523 to descend, so that the picking unit 523 reaches the first specified height where the first screen 100 on the top layer is located, and the first clamping jaw 5231 and the second clamping jaw 5232 of the picking unit 523 are controlled to approach each other to clamp the first screen 100 on the top layer. After the first screen 100 on the top layer is clamped by the picking unit 523, the lifting drive unit 522 is used to drive the picking unit 523 to rise, and the left side transfer component 52 is controlled to move horizontally to the top of the cleaning mechanism 6.

[0269] The left transfer assembly 52 places the picked up first screen 100 on the second carrier 61 of the cleaning mechanism 6, and controls the rotation and horizontal movement of the brush roller 632 to use the brush roller 632 to perform the first cleaning of the first screen 100. The brush roller 632 can be controlled to move horizontally in one direction once, or move in two directions twice, or move repeatedly for multiple times for cleaning.

[0270] After the cleaning is completed, the left transfer assembly 52 is controlled to pick up the first screen 100 on the second carrier 61 and put the first screen 100 into the container 21 of the cleaning mechanism 2 for cleaning.

[0271] After cleaning is completed, the first screen 100 in the container 21 is taken out to the first supporting bracket 31 of the drying mechanism 3 by using the left transfer assembly 52, and the drying mechanism 3 starts to blow air to the first screen 100 for drying.

[0272] At this time, the left transfer assembly 52 returns to the top of the feeding mechanism 1. In addition, the first driving member 122 in the feeding mechanism 1 drives the first support plate 1231 to rise to the height of one screen 100, so that the second screen 100 on the top layer also rises to the first specified height and waits for loading.

[0273] After the left transfer component 52 moves to the feeding mechanism 1, it will continue to transport the second screen 100 of the feeding mechanism 1 to the cleaning mechanism 6 and the washing mechanism 2 for cleaning in turn. At the same time, the first screen 100 is dried and moved away at the drying mechanism 3, and the left transfer component 52 transports the second screen 100 to the drying mechanism 3 for drying.

[0274] After the first screen 100 is dried at the drying mechanism 3, it will be transported to the detection mechanism 7 for detection via the right transfer component 52. If the cleanliness of the first screen 100 meets the standard, the first screen 100 will be placed in the left-side material receiving mechanism 4, and the left-side material receiving mechanism 4 is used to specially hold screens 100 that meet the cleanliness standard; if the cleanliness of the first screen 100 does not meet the standard, the first screen 100 will be placed in the right-side material receiving mechanism 4, and the right-side material receiving mechanism 4 is used to specially hold screens 100 that do not meet the cleanliness standard.

[0275] After the second screen 100 is dried in the drying mechanism 3, it will also be transported to the detection mechanism 7 for detection through the right transfer assembly 52, and then placed in the left or right material receiving mechanism 4 according to the detection result.

[0276] The subsequent cleaning process of the screen 100 is as described above, and the details will not be described one by one.

[0277] In addition, it should be noted that since the residual glue that needs to be cleaned from the screen 100 is mainly concentrated on the glue-containing side of the screen 100 and in the mesh 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 that is transported to the cleaning mechanism 6, the washing mechanism 2, the drying mechanism 3 and the detection mechanism 7 faces downward, so that the brush roller 632 in the cleaning mechanism 6 contacts the glue-containing side of the screen 100, and the detection mechanism 7 detects whether the glue-containing side of the screen 100 has been cleaned.
