[0044] To address the technical problems of existing technologies that rely on manual inspection and handling of solar cells, resulting in time-consuming, labor-intensive processes and reduced production efficiency, this application provides an integrated device for solar cell straightening and inspection, referring to... Figure 1 The device includes:

[0045] The sheet handling mechanism 1 is used to organize the materials in the material box 100;

[0046] Inspection unit 2 is used to acquire images of the materials and transmit the images to the control and recognition system, which can determine whether the materials meet the packaging requirements based on the images.

[0047] The recycling mechanism 3 is used to transport materials that do not meet packaging requirements to the manual operation area;

[0048] The transfer mechanism 4 is used to transfer materials between the processing mechanism 1, the inspection mechanism 2, and the recycling mechanism 3.

[0049] In this embodiment, the material specifically refers to several stacked battery cells.

[0050] The working process of the integrated battery cell straightening and testing device is as follows:

[0051] First, the sorting mechanism 1 organizes the stacked battery cells in the material box 100, arranging them neatly. Then, the transfer mechanism 4 picks up the battery cells from the material box 100 and places them at the detection mechanism 2. The detection mechanism 2 acquires an image of the battery cell and transmits it to the control and recognition system. The control and recognition system can determine whether the battery cell has missing cells, damage, or other defects, and thus whether the battery cell meets the packaging requirements. Based on the recognition results of the control and recognition system, the transfer mechanism 4 moves the battery cells that meet the packaging requirements from the detection mechanism 2 to the next packaging process, and moves the battery cells that do not meet the packaging requirements from the detection mechanism 2 to the recycling mechanism 3. Finally, the recycling mechanism 3 transports the battery cells that do not meet the packaging requirements to the manual operation area, where manual laborers repair or reject them.

[0052] As described above, the integrated solar cell straightening and testing device provided in this application can automatically complete the straightening, testing, and recycling steps of solar cells. When recycling solar cells that do not meet packaging requirements, the device does not require machine shutdown and manual handling, thus avoiding safety hazards such as personnel injury and improving production efficiency.

[0053] In this embodiment, the transfer mechanism 4 includes a first transfer component 41 and a second transfer component 42, wherein:

[0054] The first transfer component 41 includes a first robot and a material gripper. The material gripper is installed at the power output end of the first robot and is used to grip materials.

[0055] The second transfer component 42 includes a second robot and a material box gripper. The material box gripper is mounted on the power output end of the second robot and is used to grip the material box 100.

[0056] Reference Figure 2 and Figure 3 Film processing institution 1 includes:

[0057] The flipping platform 11 is used to support and fix the material box 100 containing materials, and it has a first state in which it is horizontally arranged and a second state in which it is vertically arranged.

[0058] The flip drive component 12 is used to drive the flip platform 11 to switch between the first state and the second state.

[0059] The material blocking assembly 13 includes a floating blocking member 131, which can block the opening of the material box 100 when the flipping platform 11 switches between the first state and the second state.

[0060] The air blowing assembly 14 includes at least one nozzle 141 for blowing air into the material box 100.

[0061] Continue to refer to Figure 2 and Figure 3 The baffle assembly 13 also includes:

[0062] Mounting bracket 132;

[0063] The blocking drive source 133 is slidably mounted on the fixed base 132 in the direction of approaching or moving away from the flipping platform 11, and is used to drive the blocking member 131 to move in the direction of approaching or moving away from the flipping platform 11.

[0064] The elastic element 134 is connected between the fixed base 132 and the blocking drive source 133, and is used to provide the elastic force to drive the blocking drive source 133 closer to the flipping platform 11.

[0065] The specific working process of film processing agency 1 is as follows:

[0066] Reference Figure 2 In the initial state, the flipping platform 11 is set horizontally, blocking the piston rod of the drive source 133 from retracting;

[0067] Reference Figure 3 Next, the flipping drive assembly 12 drives the flipping platform 11 to rotate from a horizontal setting to a vertical setting. When the flipping platform 11 rotates at a certain angle, the piston rod of the blocking drive source 133 extends, driving the blocking member 131 to move to the opening of the material box 100.

[0068] The flipping drive assembly 12 drives the flipping platform 11 to continue rotating. During this process, under the action of the elastic member 134, the blocking member 131 can be adjusted in the horizontal direction according to the degree of flipping of the battery cell. This flexible clamping method can avoid damage to the battery cell.

[0069] Subsequently, the air blowing assembly 14 blows air into the material box 100 through the gap on the side wall of the material box 100, causing the battery cells to disperse and fall to the bottom of the material box 100 under the action of gravity. The blocking member 131 can adaptively float during the air blowing and sorting process to further avoid damaging the battery cells.

[0070] After the air blowing is completed, the flipping drive assembly 12 drives the flipping platform 11 to rotate from a vertical position to a horizontal position. When the flipping platform 11 rotates to a certain angle, the piston rod of the blocking drive source 133 retracts, driving the blocking member 131 away from the material box 100 so as not to hinder the rotation of the flipping platform 11. After the flipping platform 11 rotates to a horizontal position, the neatly arranged battery cells fall to the bottom of the material box 100 under the action of gravity, thus completing the battery cell arrangement step.

[0071] Reference Figure 4 Testing agency 2 includes:

[0072] Material carrier 21 is used to carry materials;

[0073] The side detection component 22 is used to acquire a first image of the side of the material and transmit the first image to the control and recognition system;

[0074] The corner detection component 23 is used to acquire a second image of the corner of the material and transmit the second image to the control and recognition system.

[0075] The working process of testing agency 2 is as follows:

[0076] First, the first transfer component 41 places the sized material onto the material platform 21; then, the side detection component 22 and the corner detection component 23 take pictures of the side and corner of the material in sequence, and transmit the captured images to the control and recognition system; the control and recognition system can identify and analyze the image to determine whether there are missing pieces, damage, or other issues with the material.

[0077] As an optional embodiment, continue to refer to Figure 4 The detection mechanism 2 includes two side detection components 22, each positioned opposite to one of the two sides of the material platform 21; two corner detection components 23, each positioned opposite to one of the two corners of the material platform 21; and a rotation drive component 24 for driving the material platform 21 to rotate. The working principle of this embodiment is as follows: First, the two side detection components 22 and the two corner detection components 23 detect the shape of two sides and two corners of the material, respectively; after detection, the rotation drive component 24 drives the material platform 21 to rotate 180°; then, the two side detection components 22 and the two corner detection components 23 detect the shape of the other two sides and the other two corners of the material, respectively.

[0078] Optionally, the rotary drive assembly 24 includes a motor, a reducer, and a reducer support, wherein the motor, reducer, and material platform 21 are sequentially connected in a transmission manner, and the reducer is fixed on the reducer support. This arrangement allows the power of the motor to be transmitted to the material platform 21 via the reducer.

[0079] As another optional embodiment, the number of side detection components 22 is four and they correspond to the four sides of the material being photographed, and the number of corner detection components 23 is four and they correspond to the four corners of the material being photographed.

[0080] Continue to refer to Figure 4 Each side detection assembly 22 includes a side-shooting camera 221 and a first camera drive source (not shown in the drawings), wherein: the shooting end of the side-shooting camera 221 is set opposite to one side of the material on the material platform 21; the first camera drive source is used to drive the side-shooting camera 221 to reciprocate along the length direction of the material side corresponding to the side-shooting camera 221.

[0081] Furthermore, each set of corner detection components 23 includes a corner shooting camera 231 and a second camera driving source (not shown in the drawings), wherein: the shooting end of the corner shooting camera 231 is set opposite to a corner of the material on the material platform 21; the second camera driving source is used to drive the corner shooting camera 231 to move in a direction that approaches or moves away from the corner of the material corresponding to the corner shooting camera 231.

[0082] Optionally, the first camera drive source and the second camera drive source are cylinders or motors.

[0083] The setting of the first camera drive source increases the shooting range of the side-viewing camera 221, making the images captured by the side-viewing camera 221 more comprehensive. The setting of the second camera drive source enables the corner-viewing camera 231 to avoid the movement path of the side-viewing camera 221 during the detection process of the side detection component 22. At the same time, it enables the corner-viewing camera 231 to get as close as possible to the edge of the material during the detection process to obtain a clearer image.

[0084] Reference Figure 5 The recycling facility 3 includes:

[0085] The conveying assembly 31 includes two spaced conveyor belts 311, and the two sides of the material box 100 can be respectively attached to the two conveyor belts 311.

[0086] The lifting assembly 32 includes a lifting bracket 321, a lifting platform 322, and a lifting drive source 323. The lifting platform 322 is disposed between two conveyor belts 311, and the lifting drive source 323 is mounted on the lifting bracket 321 and is used to drive the lifting platform 322 to lift.

[0087] Specifically, the lifting support 321 includes an installation platform and multiple columns. The upper end of each column is fixed to the installation platform, and the lower end of each column is provided with a foot plate. The lifting drive source 323 is specifically a cylinder. The cylinder body of the lifting drive source 323 is fixed on the lifting support 321, and the piston rod of the lifting drive source 323 passes through the installation platform and is fixed to the lifting platform 322.

[0088] In the above structure, the lifting platform 322 is positioned between the two conveyor belts 311. The width of the lifting platform 322 is smaller than the gap between the two conveyor belts 311, so that the lifting platform 322 can pass through the gap between the two conveyor belts 311 during lifting. The width of the material box 100 is greater than the gap between the two conveyor belts 311, so that both sides of the material box 100 along the width direction can overlap the two conveyor belts 311 respectively.

[0089] Reference Figure 6 and Figure 7 The working principle of recycling mechanism 3 is as follows:

[0090] In the initial state, the lifting drive source 323 drives the lifting platform 322 to rise above the conveying surface of the conveyor belt 311; according to the identification result of the control identification system, the transfer mechanism 4 transfers the material box 100 containing the battery cells that do not meet the packaging requirements to the lifting platform 322; subsequently, the lifting drive source 323 drives the lifting platform 322 to descend below the conveying surface of the conveyor belt 311, during which the material box 100 is intercepted on the conveyor belt 311; finally, the conveyor belt 311 transports the material box 100 to the manual operation area, where the battery cells that do not meet the packaging requirements are repaired or rejected by the operator.

[0091] Continue to refer to Figure 7 The lifting assembly 32 also includes several guide rods 326, each guide rod 326 being slidably connected to the lifting bracket 321 and its upper end being fixed to the lifting platform 322.

[0092] To improve the stability of the lifting platform 322 during the lifting process, each guide rod 326 and the lifting bracket 321 are connected by a linear bearing. In addition, there are multiple guide rods 326 arranged around the periphery of the lifting drive source 323; the lower end of each guide rod 326 is fixed to a connecting plate 327, and the connecting plate 327 has a clearance hole for the lifting drive source 323 to pass through.

[0093] Reference Figure 8 and Figure 9 The bottom of the material box 100 is embedded with a positioning structure 101, and the lifting platform 322 is provided with a positioning block 324 for aligning and connecting with the positioning structure 101. In this embodiment, there are multiple positioning structures 101 (specifically four) and they are evenly distributed around the center of the material box 100 to perform multi-point positioning of the battery cell material box 100 and improve the positioning accuracy of the material box 100.

[0094] Continue to refer to Figure 9 The positioning structure 101 includes a guide block 1011, which has a tapered hole. The cross-sectional area of ​​the tapered hole gradually increases from top to bottom. The positioning block 324 can be inserted into the tapered hole. In this embodiment, the positioning block 324 includes a positioning boss and a mounting flange connected to the lower end of the positioning boss. The positioning boss is tapered to fit the shape of the tapered hole and is used to insert into the tapered hole. The mounting flange is fixed to the lifting platform 322 by countersunk screws.

[0095] Furthermore, the positioning structure 101 also includes a magnet 1012, which is clamped between the bottom plate of the material box 100 and the guide block 1011;

[0096] The magnet 1012 can be attracted and connected to the positioning block 324, and / or the positioning block 324 is provided with a Hall sensor 325.

[0097] Optionally, the guide block 1011 can be embedded into the bottom of the material box 100 by means of snap-fit, deformation pressing, screwing, or adhesive. The upper surface of the guide block 1011 is provided with a groove for accommodating the magnet 1012. When the guide block 1011 is embedded into the bottom of the material box 100, the magnet 1012 is snapped between the bottom plate of the material box 100 and the guide block 1011, thus achieving the fixed installation of the magnet 1012.

[0098] In the above structure, the magnet 1012 can be attracted and connected to the positioning block 324, thereby further restricting the position of the material box 100 relative to the lifting platform 322. A Hall sensor 325 is provided on the positioning block 324. The Hall sensor 325 can sense the magnet 1012, and thus can determine whether the material box 100 is in position based on the sensing result of the Hall sensor 325.

[0099] In this embodiment, the Hall sensor 325 is screwed to the positioning block 324.

[0100] In other embodiments, the Hall sensor 325 may be replaced with a photoelectric sensor.

[0101] Reference Figure 1 The specific working process of the integrated battery cell straightening and testing device provided in this embodiment is as follows:

[0102] Initially, the lifting platform 322 of the recycling mechanism 3 rises above the conveying surface of the conveyor belt 311;

[0103] First, the second transfer component 42 transfers the material box 100 containing the battery cells to the flipping platform 11 of the cell sorting mechanism 1, and the cell sorting mechanism 1 sorts the battery cells.

[0104] Subsequently, the first transfer component 41 removes the shaped battery cells from the material box 100 and transfers them to the material platform 21 of the testing mechanism 2, where the testing mechanism 2 checks whether the battery cells meet the packaging requirements.

[0105] If the battery cells meet the packaging requirements, the first transfer component 41 grabs the battery cells on the material carrier 21 and transfers them to the next packaging process, while the second transfer component 42 grabs the empty material box 100 on the flipping platform 11 and transfers it to the previous battery cell placement process.

[0106] If the battery cells do not meet the packaging requirements, the first transfer component 41 grabs the battery cells on the material carrier 21 and transfers them to the empty material box 100 on the flipping platform 11. Then, the second transfer component 42 grabs the material box 100 on the flipping platform 11 and transfers it to the lifting platform 322 of the recycling mechanism 3. After the Hall sensor 325 on the lifting platform 322 senses that the material box 100 is in place, the lifting platform 322 of the material box descends to below the conveying surface of the conveyor belt 311, and the material box 100 is intercepted on the conveyor belt 311. The conveyor belt 311 transports the material box 100 to the manual operation area.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
