Description

Technical Field

[0001] This application relates to the field of solar cell manufacturing technology, and in particular to a testing device. Background Technology

[0002] As solar cell production becomes increasingly automated, automated optical inspection (AOI) equipment is typically used to photograph the cells and perform area array inspection to determine whether the cells are defective.

[0003] During the manufacturing process of solar cells, the cells are fragile. When fragments fall onto the light source, they can block the light and create irregular dark areas in the image, leading to camera misjudgment. Currently, manually cleaning the fragments from the light source by stopping the machine reduces efficiency and increases labor costs. Summary of the Invention

[0004] This application provides a detection device that automatically removes debris that obstructs the light source, improving processing efficiency and saving labor costs.

[0005] This application provides a detection device, the detection device comprising:

[0006] A cell transfer mechanism, wherein the cell transfer mechanism has a detection position;

[0007] A cleaning mechanism is located below the detection position. The cleaning mechanism includes a first cleaning component for receiving debris falling from the detection position. The first cleaning component is rotatable relative to the battery cell transfer mechanism.

[0008] A backlight panel is installed on the cleaning mechanism and is located on the side of the first cleaning component away from the battery cell transmission mechanism. The light source emitted by the backlight panel can illuminate the detection position through the first cleaning component.

[0009] In one possible design, along the height direction of the detection device, the projection surface of the backlight covers the projection surface of the battery cell at the detection position, and the projection surface of the first cleaning component covers the projection surface of the backlight.

[0010] In one possible design, when the first cleaning component rotates, at least a portion of the first cleaning component facing the detection position can rotate to a position opposite to the detection position.

[0011] In one possible design, the cleaning mechanism further includes a support and a first drive assembly, wherein the first cleaning component is a conveyor belt structure;

[0012] The backlight panel and the first driving component are both mounted on the bracket, the first cleaning component is mounted on the first driving component, and the first driving component can drive the first cleaning component to rotate.

[0013] In one possible design, the first drive assembly includes a first drive element, a first drive shaft, and a second drive shaft;

[0014] The first drive shaft and the second drive shaft are rotatably mounted on the bracket, the first cleaning component is sleeved on the outer ring of the first drive shaft and the second drive shaft, and the first driving component is connected to the first drive shaft.

[0015] In one possible design, the transmission direction of the first cleaning component is perpendicular to the transmission direction of the battery cell transmission mechanism.

[0016] In one possible design, the backlight panel is disposed inside the first cleaning component.

[0017] In one possible design, the cleaning mechanism further includes a second drive member, and the bracket is mounted on the second drive member;

[0018] Before the first cleaning component is rotated, the second driving component can drive the cleaning mechanism to move away from the detection position along the height direction of the detection device.

[0019] After the first cleaning component completes its rotation, the second driving component can drive the cleaning mechanism to move towards the detection position along the height direction of the detection device.

[0020] In one possible design, the cleaning mechanism also includes a waste bin;

[0021] Along the transport direction of the first cleaning component, the waste bin is located on one side of the cleaning mechanism.

[0022] In one possible design, the cleaning mechanism further includes a second cleaning component;

[0023] Along the transmission direction of the first cleaning component, the second cleaning component is located at the side end of the first cleaning component, and when the first cleaning component rotates, the second cleaning component passes over the surface of the first cleaning component.

[0024] The beneficial effects of this embodiment are as follows: A first cleaning component is provided between the backlight panel and the detection position. Fragments falling from the battery cells at the detection position can directly fall onto the first cleaning component, which prevents the fragments from falling onto the backlight panel, reducing the risk of the light source being blocked. Automatic fragment removal is achieved by controlling the rotation of the first cleaning component, improving processing efficiency and eliminating the need for personnel to clean the fragments, thus saving labor costs.

[0047] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0048] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0050] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0051] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0052] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0053] Industrial back-inspection cameras require a light source to be installed behind the object being photographed. The object will block the light source, creating dark and luminous areas in the camera's field of view. The camera identifies the shape, area, and size of the dark areas to determine the object's current coordinates, state, and integrity. For example, it detects the object's position and angle, providing a coordinate reference for subsequent steps. It also checks the object's dimensions (length, width, diagonals, etc.) to ensure they meet tolerances. Finally, it inspects the object's edges for breakage or defects.

[0054] When debris, dust, or large particles obstruct the light source, they create irregular dark areas in the camera image, leading to misjudgment. Current solutions typically involve stopping the camera and manually cleaning away the debris. However, manual processing is slow and increases labor costs.

[0055] Therefore, this embodiment provides a detection device. Figure 1 This is a schematic diagram of the testing device 1. The testing device 1 includes a cell transfer mechanism 11, a backlight panel 13, and a back inspection camera (not shown in the figure). Along the height direction Z of the testing device 1, the backlight panel 13 is positioned below the cell transfer mechanism 11. The light source emitted by the backlight panel 13 can illuminate the cell transfer mechanism 11, and the position where the light source emitted by the backlight panel 13 illuminates the cell transfer mechanism 11 is the detection position 111 of the cell transfer mechanism 11. The back inspection camera is mounted above the cell transfer mechanism 11, and the detection position 111 of the cell transfer mechanism 11 is located within the field of view of the back inspection camera.

[0056] The cell transfer mechanism 11 can be a conveyor belt mechanism, including multiple conveyor belts operating simultaneously. The slicing of the cells 2 allows them to be transported to each conveyor belt of the cell transfer mechanism 11, which then transfers the cells 2 to the next workstation. The light emitted by the backlight panel 13 simultaneously illuminates each conveyor belt, giving each conveyor belt a detection position 111. During the transfer of the cells 2 on the cell transfer mechanism 11, each cell 2 passes through the detection position 111. At this time, the cell 2 blocks the light emitted by the backlight panel 13, and when the back inspection camera takes a picture from above, the area of ​​the cell 2 appears as a dark area.

[0057] It should be noted that the width of the battery cell 2 is greater than the width of the conveyor belt, so that when the battery cell 2 is placed on the conveyor belt, a portion of the structure in the width direction of the battery cell 2 can extend out of the conveyor belt, so that the back inspection camera can capture the dark area of ​​the battery cell 2.

[0058] Figure 2 This is a schematic diagram of the testing device 1 from another perspective. The testing device 1 also includes a cleaning mechanism 12. Along the height direction Z of the testing device 1, the cleaning mechanism 12 is located below the cell transfer mechanism 11, specifically below the detection position 111. A backlight panel 13 is installed on the side of the cleaning mechanism 12 away from the cell transfer mechanism 11. The light source emitted by the backlight panel 13 can illuminate the detection position 111 through the cleaning mechanism 12. Along the length direction Y of the testing device 1, each cell 2 can be transported above the backlight panel 13 via the cell transfer mechanism 11, so that each cell 2 can be illuminated by the backlight panel 13.

[0059] Please continue to refer to this. Figure 2The cleaning mechanism 12 includes a first cleaning component 121, which is located along the height direction Z of the detection device 1. At least a portion of the first cleaning component 121 is disposed between the detection position 111 and the backlight panel 13. The first cleaning component 121 can catch debris falling from the detection position 111. The first cleaning component 121 can rotate relative to the battery cell transfer mechanism 11 to remove debris from the first cleaning component 121 so as not to interfere with subsequent photography.

[0060] The first cleaning component 121 is made of a light-transmitting material, so that the light source emitted by the backlight panel 13 can pass through the first cleaning component 121 and illuminate the detection position 111 of the battery cell transmission mechanism 11.

[0061] In other words, a first cleaning element 121 is set between the backlight panel 13 and the detection position 111. Fragments falling from the battery cell 2 at the detection position 111 can fall directly onto the first cleaning element 121, which prevents them from falling onto the backlight panel 13. When the back inspection camera detects irregular dark areas in the photo, it determines that the battery cell 2 is unqualified. When the back inspection camera determines that the dark areas of the battery cell 2 are continuously unqualified, it may be because there are fragments on the first cleaning element 121. In this case, the first cleaning element 121 can be driven to rotate to remove the fragments.

[0062] Understandably, in the process of determining that consecutive defective battery cells 2 are driven to rotate the first cleaning component 121, the number of consecutive defective battery cells 2 can be 3, 4, 5, 6, etc. For example, when the back inspection camera determines that the number of consecutive defective battery cells 2 is 5, the first cleaning component 121 can be driven to rotate to remove the debris on the first cleaning component 121. The specific settings can be determined according to the actual situation, and this embodiment does not limit it.

[0063] The testing device 1 includes a control module. The back inspection camera, the battery cell transfer mechanism 11, and the cleaning mechanism 12 are all electrically connected to the control module. When the back inspection camera detects that the dark area of ​​the battery cell 2 being photographed is continuously unqualified, the back inspection camera can transmit a signal to the control module. The control module can control the cleaning mechanism 12 to drive the first cleaning component 121 to rotate, so as to remove the debris on the first cleaning component 121.

[0064] In this embodiment, by setting up a cleaning mechanism 12 to receive fragments of the battery cell 2 falling from the detection position 111, the risk of fragments falling onto the backlight panel 13 is reduced, thereby reducing the risk of the light source being blocked. By controlling the rotation of the cleaning mechanism 12, the fragments are automatically removed, improving processing efficiency and eliminating the need for staff to clean the fragments, thus saving labor costs.

[0065] Please continue to refer to this. Figure 2Along the height direction Z of the detection device 1, the projection surface of the backlight panel 13 covers the projection surface of the battery cell 2 at the detection position 111. That is, the projection surface of the battery cell 2 at the detection position 111 in the height direction Z of the detection device 1 is located within the projection surface of the backlight panel 13 in the height direction Z of the detection device 1, and the projection surface of the backlight panel 13 is larger than the projection surface of the battery cell 2 at the detection position 111, so that the light source emitted by the backlight panel 13 can surround the battery cell 2 at the detection position 111, so that there will be dark areas and light-emitting areas in the shooting field of the back inspection camera, so that the back inspection camera can identify whether the dark area is a regular dark area.

[0066] Please continue to refer to this. Figure 2 Along the height direction Z of the detection device 1, the projection surface of the first cleaning component 121 covers the projection surface of the backlight panel 13. That is, the projection surface of the backlight panel 13 in the height direction Z of the detection device 1 is located within the projection surface of the first cleaning component 121 in the height direction Z of the detection device 1, so that the first cleaning component 121 can prevent fragments on the battery cell 2 of the detection position 111 from falling onto the backlight panel 13.

[0067] Understandably, in other embodiments, based on the fact that the projection surface of the first cleaning component 121 covers the projection surface of the battery cell 2 of the detection position 111, the projection surface of the backlight panel 13 in the height direction of the detection device 1 can also be slightly larger than the projection surface of the first cleaning component 121 in the height direction Z of the detection device 1, so that the backlight panel 13 can be connected to other components (such as the components supporting the backlight panel 13). The specific settings can be determined according to the actual situation, and this embodiment does not limit it.

[0068] In some embodiments, when the first cleaning component 121 rotates, a portion of the first cleaning component 121 facing the detection position 111 can rotate to a position facing away from the detection position 111. That is, when the back inspection camera identifies that the battery cell 2 is continuously unqualified, the control module can control the first cleaning component 121 of the cleaning mechanism 12 to rotate, so that a portion of the first cleaning component 121 initially facing the battery cell 2 rotates to the side facing away from the battery cell 2, thereby completing the cleaning of the first cleaning component 121 and allowing the inspection device 1 to continue operating.

[0069] Specifically, the side of the first cleaning component 121 that initially faces the battery cell transfer mechanism 11 is designated as the receiving surface. Before the first cleaning component 121 rotates, the receiving surface of the first cleaning component 121 faces upwards. After the first cleaning component 121 rotates, it must rotate at least to a position where the receiving surface faces downwards, so that the fragments on the receiving surface of the first cleaning component 121 can fall off.

[0070] Alternatively, in other embodiments, the control module can control the first cleaning component 121 of the cleaning mechanism 12 to rotate one revolution to remove debris from the first cleaning component 121. Specifically, the side of the first cleaning component 121 that initially faces the battery cell transfer mechanism 11 is designated as the receiving surface. Before the first cleaning component 121 rotates, the receiving surface of the first cleaning component 121 faces upwards. After the first cleaning component 121 rotates, the receiving surface of the first cleaning component 121 remains facing upwards as it rotates one revolution.

[0071] In some embodiments, the first cleaning component 121 is a light-transmitting conveyor belt structure, which can have a large receiving surface and effectively prevent fragments on the battery cell 2 at the detection position 111 from falling onto the backlight panel 13. Furthermore, by configuring the first cleaning component 121 as a conveyor belt structure, the first cleaning component 121 requires less space to move when removing fragments, allowing the cleaning mechanism 12 to be placed in the empty space below the battery cell conveying mechanism 11, thus reducing the space occupied by the first cleaning component 121.

[0072] in, Figure 3 This is a schematic diagram showing the distribution of the first cleaning component 121 and the backlight panel 13 in one embodiment. The backlight panel 13 can be disposed within the annular circle formed by the first cleaning component 121 to reduce the risk of debris on the first cleaning component 121 falling onto the backlight panel 13 when the first cleaning component 121 rotates.

[0073] That's understandable, please continue to refer to it. Figure 3 When the backlight panel 13 is disposed within the inner ring of the first cleaning member 121, a portion of the structure of the backlight panel 13 can extend out of the first cleaning member 121 to facilitate connection with other supporting components (such as the bracket 122 described below). Alternatively, other supporting components can extend into the inner ring of the first cleaning member 121 and connect with it. Specific configurations can be determined according to actual conditions, and this embodiment does not impose limitations.

[0074] Alternatively, please refer to Figure 4 , Figure 4 This is a schematic diagram showing the distribution of the first cleaning component 121 and the backlight panel 13 in another embodiment. The backlight panel 13 may be disposed below the first cleaning component 121.

[0075] It should be noted that when the backlight panel 13 is positioned below the first cleaning component 121, the length of the first cleaning component 121 must be greater than the length of the backlight panel 13 along the transmission direction of the first cleaning component 121. The backlight panel 13 is positioned at the end of the first cleaning component 121 and rotates from the upward to the downward end away from the receiving surface of the first cleaning component 121. Figure 4 An arrow is provided at one end of the first cleaning component 121 to reduce the risk of debris falling onto the backlight panel 13 when the receiving surface of the first cleaning component 121 is rotated to be positioned opposite the backlight panel 13.

[0076] Figure 5 This is a schematic diagram of the cleaning mechanism 12. In some embodiments, the cleaning mechanism 12 further includes a bracket 122 and a first drive assembly 123. Both the backlight panel 13 and the first drive assembly 123 are mounted on the bracket 122. The first cleaning component 121 is mounted on the first drive assembly 123, and the first drive assembly 123 can drive the first cleaning component 121 to rotate, thereby removing debris from the first cleaning component 121.

[0077] Please continue to refer to this. Figure 5 The first drive assembly 123 includes a first drive member 123a, a first drive shaft 123b, and a second drive shaft 123c. The first drive shaft 123b and the second drive shaft 123c are rotatably mounted on the bracket 122. The first cleaning member 121 is sleeved on the outer ring of the first drive shaft 123b and the second drive shaft 123c. The first drive member 123a is connected to the first drive shaft 123b.

[0078] Specifically, the first drive shaft 123b and the second drive shaft 123c are distributed along the transmission direction of the first cleaning component 121, and are connected by the first cleaning component 121. The first driving component 123a can drive the first drive shaft 123b to rotate. The friction between the first drive shaft 123b and the first cleaning component 121 causes the first cleaning component 121 to rotate, and at the same time, the friction between the first cleaning component 121 and the second drive shaft 123c causes the second drive shaft 123c to rotate, thereby realizing the rotation of the first cleaning component 121.

[0079] Understandably, the first driving component 123a can also be connected to the second drive shaft 123c, and the second drive shaft 123c drives the first drive shaft 123b to rotate through the first cleaning component 121. The specific configuration can be determined according to actual conditions, and this embodiment does not impose any limitations.

[0080] In this embodiment, the first driving component 123a can be a motor 123a1, the driving end of which is connected to the first transmission shaft 123b, driving the first transmission shaft 123b to rotate. Alternatively, the first driving component 123a can also be a motor 123a1 and a transmission belt 123a2, with one end of the transmission belt 123a2 sleeved on the driving end of the motor 123a1 and the other end of the transmission belt 123a2 sleeved on the first transmission shaft 123b, allowing the motor 123a1 to drive the first transmission shaft 123b to rotate via the transmission belt 123a2. Furthermore, the first driving component 123a can also be other components, which can be specifically set according to actual conditions; this embodiment does not impose any limitations on this.

[0081] Please refer to the reference. Figure 2 and Figure 5In some embodiments, the cleaning mechanism 12 further includes a second drive member 124, and the bracket 122 is mounted on the second drive member 124. Before the first cleaning member 121 is rotated, the second drive member 124 can drive the cleaning mechanism 12 to move away from the detection position 111 along the height direction Z of the detection device 1. After the first cleaning member 121 has completed its rotation, the second drive member 124 can drive the cleaning mechanism 12 to move closer to the detection position 111 along the height direction Z of the detection device 1.

[0082] In other words, when the back inspection camera identifies consecutive non-conforming battery cells 2, the control module first controls the second drive component 124 to drive the bracket 122 to move away from the battery cell transfer mechanism 11, thereby moving the first cleaning component 121 away from the battery cells 2 on the battery cell transfer mechanism 11. Once the second drive component 124 has moved the bracket 122 into position, the control module controls the first drive component 123a to drive the first transmission shaft 123b to rotate. The first transmission shaft 123b then drives the first cleaning component 121 to rotate, causing the debris on the first cleaning component 121 to fall off. After the first drive component 123a drives the first cleaning component 121 to rotate one revolution, the control module then controls the second drive component 124 to drive the bracket 122 to move closer to the battery cell transfer mechanism 11, thereby returning the first cleaning component 121 to its initial position.

[0083] The second driving component 124 can drive the bracket 122 to descend by a distance of 3mm-5mm, so that there is a certain distance between the first cleaning component 121 and the battery cell transmission mechanism 11, so as to avoid the first cleaning component 121 hitting the battery cell 2 when it rotates, or the fragments on the first cleaning component 121 hitting the battery cell 2, which would cause damage to the battery cell 2.

[0084] In one embodiment, the second driving component 124 can be a cylinder, which drives the bracket 122 to rise or fall. Alternatively, the second driving component 124 can also be a component that cooperates with a motor 123a1 and a linkage mechanism, with the motor 123a1 driving the linkage mechanism to raise or lower the bracket 122. Still other components are also possible; the specific design can be determined according to actual conditions, and this embodiment does not impose any limitations.

[0085] Please continue to refer to the reference. Figure 1 and Figure 2 In some embodiments, the transmission direction B of the first cleaning component 121 is set approximately perpendicular to the transmission direction A of the battery cell transmission mechanism 11, so that the bracket 122 of the cleaning mechanism 12 is staggered from the support structure of the battery cell transmission mechanism 11, so as to facilitate the installation and maintenance of the cleaning mechanism 12 and the battery cell transmission mechanism 11.

[0086] Alternatively, in other embodiments, the transmission direction B of the first cleaning component 121 and the transmission direction A of the battery cell transmission mechanism 11 can be set approximately parallel. The specific direction can be set according to actual conditions, and this embodiment does not impose any limitations.

[0087] In some embodiments, the cleaning mechanism 12 further includes a waste bin (not shown in the figure), located on one side of the cleaning mechanism 12 along the conveying direction B of the first cleaning member 121. That is, when the receiving surface of the first cleaning member 121 rotates from facing upward to facing downward, the debris on the receiving surface of the first cleaning member 121 can fall into the waste bin for easy collection and cleaning of the debris.

[0088] In some embodiments, the cleaning mechanism 12 further includes a second cleaning component (not shown) located at the side end of the first cleaning component 121 along the transmission direction B of the first cleaning component 121. The second cleaning component can be mounted above the waste bin via a support rod. When the first cleaning component 121 rotates, the second cleaning component passes over the surface of the first cleaning component 121. That is, when the receiving surface of the first cleaning component 121 rotates from facing upwards to facing downwards, the receiving surface of the first cleaning component 121 will pass over the second cleaning component, allowing the second cleaning component to clean the receiving surface and sweep away debris from the receiving surface, reducing the risk that debris on the receiving surface may not fall off.

[0089] The second cleaning component can be a brush or other similar parts, and the specific design can be determined according to the actual situation. This embodiment does not impose any limitations on this component.

[0090] Alternatively, in other embodiments, the first cleaning component 121 may adopt other structures. For example, a plate-like structure connected to the rotating arm, with the backlight plate 13 mounted on the back of the plate-like structure and able to rotate together with it. Specific configurations can be determined according to actual conditions, and this embodiment does not impose limitations.

[0091] In general, in one embodiment, when the battery cell 2 is transported on the battery cell transport mechanism 11, a back inspection camera photographs the battery cell 2 and determines whether the battery cell 2 is qualified based on the dark area formed by the battery cell 2. When the back inspection camera detects that the battery cell 2 is continuously unqualified, the back inspection camera transmits the information to the control module. The control module controls the battery cell transport mechanism 11 to stop, and at the same time, the control module controls the second drive member 124 to drive the bracket 122 to descend, so that the first cleaning member 121 is separated from the battery cell 2 by a certain distance. Then, the control module controls the first drive member 123a to drive the first cleaning member 121 to rotate. When the first cleaning member 121 rotates, its surface will pass over the second cleaning member, so that the second cleaning member can sweep away the debris on the first cleaning member 121, causing the debris to fall into the waste bin. When the first cleaning member 121 has rotated one revolution, the cleaning is completed, and the control module can control the battery cell transport mechanism 11 to continue operating.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
