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 process of processing photovoltaic modules, it is necessary to connect the solder strips and the cell pieces into a cell string. In order to ensure that the solder strips and the cell pieces are reliably connected, a glue applying device is usually used to apply glue on the solder strips after the cell string is formed, or the glue applying device is used to apply glue on the cell pieces before the cell string is formed. The glue applying device includes a screen and a scraper assembly. The screen has an array of screen holes arranged therein and is used to hold the glue. The scraper assembly can scrape the glue on the screen from the screen holes to the solder strips. After the glue is solidified, the solder strips and the cell pieces are reliably adhered. After the screen is used for a long time, the glue or other impurities on the screen can easily block the screen holes. In order to ensure normal glue application, the screen is usually cleaned regularly by manual operation. However, the efficiency of manual cleaning is low and cannot meet the needs of efficient production. CONTENT OF THE UTILITY MODEL

[0246] The sixth guide rail 731 is horizontally arranged on the support table 74, and the screen placing rack 71 is in sliding connection with the sixth guide rail 731.

[0247] The thirteenth driving member 733 is in driving connection with the third synchronous belt 732, and the thirteenth driving member 733 is a motor. The thirteenth driving member 733 is configured to drive the third synchronous belt 732 to rotate.

[0248] The screen placing rack 71 is fixedly connected with a part of the belt body of the third synchronous belt 732, so that the screen placing rack 71 can advance or retreat along the sixth guide rail 731 with the rotation of the third synchronous belt 732. In the process that the screen 100 on the screen placing rack 71 moves, the screen 100 passes above the detection camera 72, so that the shooting range of the detection camera 72 can cover all the lower surfaces of the screen 100, to detect the cleanliness of the screen 100. If the width of the screen 100 in the direction perpendicular to the moving direction of the screen placing rack 71 is relatively wide, two or more detection cameras 72 can be arranged in the direction perpendicular to the moving direction of the screen placing rack 71, to ensure that after the screen 100 passes above the detection cameras 72 once in one direction, all the detection cameras 72 can collectively shoot the lower surfaces of the screen 100.

[0249] As another embodiment, the screen placing rack 71 is stationary, i.e., the screen 100 on the screen placing rack 71 is stationary. The bracket for mounting the detection camera 72 is driven by a cylinder or a linear module, to realize the movability of the detection camera 72, so as to drive the detection camera 72 to shoot and detect the entire lower surface of the screen 100.

[0250] Optionally, as shown in FIG. 6, the detection mechanism 7 further comprises a first detection camera 71 and a second detection camera 72. Figures 13-14 ​The screen placing rack 71 is provided with a plurality of second limiting columns 711 for limiting the circumference of the screen 100. Figure 13 Each corner of the screen 100 corresponds to two second limiting columns 711.

[0251] The screen placing rack 71 can support the screen 100, and the plurality of second limiting columns 711 provided on the screen placing rack 71 can limit and fix the screen 100.

[0252] Optionally, continuing to refer to Figures 13-14 One side of the screen placing rack 71 is provided with a second pushing assembly 712.

[0253] The second pushing assembly 712 is configured to push one end of the screen 100 located on the screen placing rack 71 in the horizontal direction, so that the screen 100 on the screen placing rack 71 is pressed against the second limiting column 711.

[0254] Optionally, continuing to refer to Figures 13-14 The second pushing assembly 712 includes a third mounting rack 7121, a fourteenth driving member 7122, and a second pushing head 7123, wherein:

[0255] The fourteenth driving member 7122 is installed on the third mounting rack 7121, and the fourteenth driving member 7122 can be a pneumatic cylinder. The fourteenth driving member 7122 is drivingly connected with the second pushing head 7123.

[0256] The fourteenth driving member 7122 is configured to drive the second pushing head 7123 to push one end of the screen 100 located on the screen placing rack 71 in the horizontal direction, so that the screen 100 on the screen placing rack 71 is pressed against the second limiting column 711. The design of the screen placing rack 71 can ensure that the screen 100 remains stable during detection, avoiding detection errors caused by shaking. Through stable support, the reliability and consistency of detection can be improved.

[0257] Optionally, continuing to refer to Figures 13-14 The third mounting rack 7121 is installed on the support table 74.

[0258] Optionally, continuing to refer to Figure 14 The support table 74 in the detection mechanism 7 is provided with a first waste collection area, a detection area, and a second waste collection area along the moving direction of the screen placing rack 71.

[0259] The detection area of the support table 74 is provided with an avoiding hole 741, and the detection camera 72 is arranged below the avoiding hole 741.

[0260] When the screen 100 moves to the position of the avoiding hole 741, the lower surface of the screen 100 can be exposed in the field of view of the detection camera 72.

[0261] The screen placing rack 71 can move back and forth between the first waste collection area, the detection area, and the second waste collection area; the screen placing rack 71 is located above the detection camera 72 when it moves to the detection area;

[0262] The first waste collection area and the second waste collection area are respectively provided with a second waste box 75 and a third waste box 76; the screen placing rack 71 moves above the second waste box 75 and the third waste box 76, and the second waste box 75 and the third waste box 76 are both used to collect the waste falling from the screen 100.

[0263] Optionally, referring back to Figures 13-14 , the detection mechanism 7 further comprises at least one light source 77 configured to illuminate the detection area. When the screen placing rack 71 moves to the detection area, the light source 77 can illuminate the screen 100 on the screen placing rack 71.

[0264] Optionally, referring back to Figures 13-14 , the light source 77 is installed on the third mounting rack 7121.

[0265] The addition of the light source 77 can provide sufficient and uniform illumination, ensuring the stability of the light conditions in the detection environment. The stability and sufficiency of the illumination are crucial to the imaging quality of the detection camera 72, helping to improve the accuracy and reliability of the detection. Good lighting conditions can enable the camera to capture the details of the surface of the screen 100 more clearly, reducing false positives and missed detections.

[0266] 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 cleaning mechanism 6, the washing mechanism 2, the drying mechanism 3, the detection mechanism 7, 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 cleaning mechanism 6, the washing mechanism 2, the drying mechanism 3, the detection mechanism 7, and the two material collecting mechanisms 4, and 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:

[0267] Pull out the first material frame 11 to the replenishment position, and manually stack the screen 100 to be cleaned into the first material frame 11 one by one. After the replenishment is completed, push the first material frame 11 back to the original position, and drive the first driving member 122 in the feeding mechanism 1 to raise the first supporting plate 1231, and use the first supporting plate 1231 to support the screen 100 in the first material frame 11 to move upwards until the first screen 100 on the top layer reaches the first specified height and stops.

[0268] The left side transfer assembly 52 is controlled to move along the conveying track 51 to above 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 top layer first screen printing plate 100 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 top layer first screen printing plate 100. After the top layer first screen printing plate 100 is clamped by the pickup part 523, the lifting driving part 522 drives the pickup part 523 to ascend, and the left side transfer assembly 52 is controlled to move transversely to above the cleaning mechanism 6.

[0269] The left side transfer assembly 52 places the picked first screen printing plate 100 on the second bearing frame 61 of the cleaning mechanism 6. The brush roller 632 is controlled to rotate and move horizontally to clean the first screen printing plate 100 by the brush roller 632. The brush roller 632 can be controlled to move horizontally in one direction once, or to move in two directions twice, or to move repeatedly for multiple times.

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

[0271] After the cleaning is completed, the left side transfer assembly 52 is controlled to pick up the first screen printing plate 100 on the second bearing frame 61 and place the first screen printing plate 100 into the container 21 of the cleaning mechanism 2 for cleaning.

[0272] At this time, the left side transfer assembly 52 returns to above the feeding mechanism 1 again. In addition, the first driving part 122 in the feeding mechanism 1 drives the first supporting plate 1231 to ascend by the height of one screen printing plate 100, so that the second screen printing plate 100 located on the top layer also ascends to the first specified height and waits for feeding.

[0273] After the left side transfer assembly 52 moves to the feeding mechanism 1, the second screen printing plate 100 of the feeding mechanism 1 is continuously carried to the cleaning mechanism 6 and the cleaning mechanism 2 for cleaning. Meanwhile, the first screen printing plate 100 is carried away after the drying in the drying mechanism 3 is completed, and the second screen printing plate 100 is carried to the drying mechanism 3 by the left side transfer assembly 52 for drying treatment.

[0274] The first screen 100 is first carried to the detection mechanism 7 by the right side moving assembly 52 after being dried by the drying mechanism 3. If the cleanliness of the first screen 100 meets the standard, the first screen 100 is placed in the left side material receiving mechanism 4 which is used to specially hold the screen 100 meeting the standard. If the cleanliness of the first screen 100 does not meet the standard, the first screen 100 is placed in the right side material receiving mechanism 4 which is used to specially hold the screen 100 not meeting the standard.

[0275] The second screen 100 is also first carried to the detection mechanism 7 by the right side moving assembly 52 after being dried by the drying mechanism 3. Then, the second screen 100 is placed in the left side or right side material receiving mechanism 4 according to the detection result.

[0276] The cleaning process of the subsequent screen 100 is the same as above and will not be described in detail.

[0277] In addition, it should be noted that the residual glue which needs to be cleaned of the screen 100 mainly concentrates on the glue holding side of the screen 100 and the screen hole. Therefore, when the screen 100 is stacked in the first material frame 11, the glue holding side of the screen 100 faces downward. In this way, the glue holding side of the screen 100 carried to the cleaning mechanism 6, the cleaning mechanism 2, the drying mechanism 3 and the detection mechanism 7 all faces downward. In this way, the brush roller 632 in the cleaning mechanism 6 contacts the glue holding side of the screen 100 and the detection mechanism 7 detects whether the glue holding side of the screen 100 is cleaned.

It should be understood by those skilled in the art that the description in the embodiments is only exemplary. All changes made without departing from the true spirit and scope of the present application should belong to the protection scope of the present application.
