Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic industry, and in particular to a structure for automatically sliding and cleaning debris on a back AOI glass. Background Art

[0002] At present, in the loading station of the sorting and testing section of the battery workshop in the photovoltaic industry, the AOI back-side inspection uses a suction cup to transfer the cells. However, the thickness of the cells is gradually becoming thinner with the development of the industry, and because the cells are relatively brittle, fragments are easily generated during the suction cup transfer process and fall into the back-side inspection chassis. In order to protect the back camera from damage, the camera position needs to be protected. Currently, a piece of glass is placed above the chassis. On the one hand, it does not affect the acquisition of pictures taken by the camera, and on the other hand, it plays a role in protecting the camera.

[0003] Although this structure protects the camera from falling debris and causing damage to the camera, it also has the following effects during use:

[0004] 1. The generated debris will fall on the glass, thereby blocking the camera shooting area, causing AOI misidentification and resulting in batch downgrade;

[0005] 2. Fragments fall on the glass, causing the glass surface to be scratched due to frequent wiping by personnel during use, thus affecting the test results;

[0006] 3. Glass in a horizontal position makes it inconvenient for personnel to remove fragments, which may easily cause hand injuries. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and proposes a structure for automatically sliding off and cleaning the debris on the back AOI glass.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A structure for automatically sliding off and cleaning debris on a rear AOI glass, comprising:

[0010] A chassis, a camera is fixedly connected to the lower inner wall of the chassis, and a shooting port is opened on the top of the chassis;

[0011] An automatic sliding cleaning mechanism comprises a transparent glass which is fixedly connected to the inner wall of the chassis at an angle, the angle between the side wall of the transparent glass and the inner wall of the chassis is 45°, a discharge port is provided on the side wall of the chassis near the bottom of the transparent glass, and the transparent glass is arranged above the camera.

[0012] Preferably, the chassis is provided with a collecting mechanism for collecting fragments on the back AOI glass, the collecting mechanism includes a fixing plate fixedly connected to the side wall of the chassis by a bracket, a collecting frame is attached to the upper end of the fixing plate, a groove is opened on the side wall of the chassis, the side wall of the collecting frame is located in the groove, and the collecting frame is located below the discharge port.

[0015] Preferably, the side wall of the chassis close to the shooting port is arranged to be inclined downward.

[0016] The utility model has the following beneficial effects:

[0017] 1. An automatic sliding cleaning mechanism is set up. After the debris falls on the transparent glass, it easily slides down from the inclined transparent glass under the action of gravity, and finally flows out through the discharge port, so that the debris is cleaned thoroughly to avoid the debris falling on the top of the glass, thereby blocking the camera shooting area, causing AOI misidentification, resulting in batch degradation, and low use and maintenance costs, no need for personnel to perform frequent maintenance, avoid scratches on the glass surface, etc., causing damage to the glass itself and injuries to personnel's hands, and avoid debris falling on the glass, resulting in frequent wiping of the glass during use, causing scratches on the glass surface, thereby affecting the test results, and horizontal glass, which is inconvenient for personnel to take fragments and easily causes hand injuries.

[0018] 2. By setting up an air blowing mechanism, the external gas can flow out from multiple air holes through the air inlet pipe and the air jet pipe, and blow air to the upper surface of the transparent glass, thereby speeding up the cleaning of the debris on the upper surface of the transparent glass, avoiding blocking the camera shooting area, causing AOI misrecognition, and resulting in batch reduction.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 3 A structure for automatically sliding and cleaning debris on the back AOI glass includes a chassis 1, a camera 2 is fixedly connected to the lower inner wall of the chassis 1, and the back of the battery cell can be identified. It is a prior art. A shooting port 3 is opened on the top of the chassis 1, and the side wall of the chassis 1 near the shooting port 3 is tilted downward.

[0025] The automatic sliding cleaning mechanism includes a transparent glass 4 which is fixedly connected to the inner wall of the chassis 1 at an angle, and the angle between the side wall of the transparent glass 4 and the inner wall of the chassis 1 is 45°. A discharge port 5 is provided on the side wall of the chassis 1 near the bottom of the transparent glass 4, and the transparent glass 4 is arranged above the camera 2.

[0026] Furthermore, the fragments generated by the battery cell during the suction cup transmission process will enter the chassis 1 through the shooting port 3, and then the fragments will fall on the transparent glass 4. Since the surface of the transparent glass 4 is smooth, the fragments will easily slide down from the inclined transparent glass 4 under the action of gravity, and finally flow out through the discharge port 5, so that the fragments are thoroughly cleaned, and the generated fragments are prevented from falling on the glass, thereby blocking the camera shooting area, causing AOI misidentification, and leading to batch degradation. In addition, the use and maintenance costs are low, and personnel do not need to perform maintenance frequently, so as to avoid scratches on the glass surface, etc., causing damage to the glass itself and injuries to personnel's hands, and to avoid fragments falling on the glass, resulting in frequent wiping of the glass by personnel during use, causing scratches on the glass surface, thereby affecting the test results, and the glass in a horizontal position is inconvenient for personnel to take fragments, which can easily cause hand injuries.

[0027] It should be noted that, viewed from the side, the width of the transparent glass 4 and the width of the discharge port 5 are consistent with the size of the inner wall of the chassis 1 .

[0028] The chassis 1 is provided with a collecting mechanism for collecting fragments on the back AOI glass, and the collecting mechanism includes a fixing plate 6 fixedly connected to the side wall of the chassis 1 through a bracket 10, and a collecting frame 7 is attached to the upper end of the fixing plate 6. A groove 8 is opened on the side wall of the chassis 1, and the side wall of the collecting frame 7 is located in the groove 8. The collecting frame 7 is located below the discharge port 5. In addition, the inner wall of the collecting frame 7 matches the inner wall of the discharge port 5, so that all the fragments flowing out of the discharge port 5 can enter the collecting frame 7.

[0029] The side wall of the fixing plate 6 is connected to the lower end of the collecting frame 7 by a plurality of bolts 9 to ensure the stability of the collecting frame 7 .

[0030] The chassis 1 is provided with a blowing mechanism for blowing air onto the transparent glass 4, and the blowing mechanism includes an air inlet pipe 11 fixedly connected to the upper inner wall of the chassis 1, one end of the air inlet pipe 11 is located inside the chassis 1 and is fixedly connected to an air jet pipe 12, and the air jet pipe 12 is provided with a plurality of air jet holes 13 near the inner wall of the transparent glass 4, and the air jet pipe 12 is located above the side wall of the transparent glass 4.

[0031] Furthermore, the air inlet pipe 11 is connected to an external air pump, which can control the air pump to pump air into the air inlet pipe 11. This is a prior art. The external gas can then flow out from multiple air jet holes 13 through the air inlet pipe 11 and the air jet pipe 12 to blow air onto the upper surface of the transparent glass 4, thereby speeding up the cleaning of debris on the upper surface of the transparent glass 4 and avoiding blocking the camera shooting area, causing misidentification of AOI, and resulting in batch degradation.

[0032] When the back side of the cell is inspected using the AOI back side inspection box, the box 1 is first set directly below the cell, and the cell is transferred by the suction cup, which is the prior art. When the cell moves from directly above the shooting port 3, the camera 2 can shoot the back side of the cell through the shooting port 3, so as to perform AOI identification.

[0033] If the battery cell is broken into pieces during the conveying process, the broken pieces that fall into the chassis 1 through the shooting port 3 will fall on the transparent glass 4. Since the surface of the transparent glass 4 is smooth, the broken pieces will easily slide down from the inclined transparent glass 4 under the action of gravity, and finally flow out through the discharge port 5, so that the broken pieces can be cleaned up thoroughly, and the use and maintenance costs are low, and personnel do not need to perform maintenance frequently, so as to avoid scratches on the glass surface, etc., which may cause damage to the glass itself and injuries to personnel's hands.

[0034] At this time, the external air pump can be started, and the external gas will flow out from the multiple air injection holes 13 through the air inlet pipe 11 and the air injection pipe 12, blowing air to the upper surface of the transparent glass 4, speeding up the cleaning of the debris on the upper surface of the transparent glass 4, avoiding blocking the camera shooting area, causing AOI misrecognition, and resulting in batch degradation;

[0035] The debris flowing out of the discharge port 5 will be collected in the collecting frame 7. Later, it is only necessary to rotate a plurality of bolts 9 to separate the collecting frame 7, and then remove the collecting frame 7 to clean the debris inside.

[0036] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
