Description

Technical Field

[0001] The present invention relates to the technical field of battery cell carrier detection, and more specifically, to a detection jig applied to battery cell carriers. Background Art

[0002] Photovoltaic cells are semiconductor components that convert solar energy into electricity. Primarily made of semiconductor materials like silicon, they play a crucial role in many aspects of the photovoltaic industry chain. Cell carriers are primarily used for cleaning and handling photovoltaic cells during production. They hold and protect the cells, ensuring they are not damaged during cleaning or other handling procedures.

[0003] The photovoltaic cell carrier is a monolithic frame structure with multiple rows of slots for placing the cells. During the manufacturing process, it is crucial to ensure that the cell carrier, especially the sidewalls and bottom of the slots, are flat and burr-free. This is because burrs on uneven surfaces can scratch the cell surface when removing the cell, potentially damaging its surface structure and directly affecting its photovoltaic conversion efficiency, mechanical stability, and long-term reliability.

[0004] In the prior art, a probe is installed on the micrometer, and the probe is moved from top to bottom to detect whether the side wall of the placement groove is flat and has burrs. However, if there are burrs on the bottom of the placement groove, the offset direction of the probe during detection is different from the offset direction when detecting the side wall. It is impossible to continue to detect the bottom after detecting the side wall. Another set of detection probes with different offset directions must be used for detection, resulting in increased equipment costs and reduced detection efficiency. Summary of the Invention

[0005] The present invention provides an inspection jig for battery cell carriers, and the problem to be solved is: since the offset directions of the probes when inspecting the side walls and the bottom walls of the placement groove are different, the existing technology cannot continue to inspect the bottom wall after inspecting the side walls, and another set of inspection probes with different offset directions need to be used for inspection.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 10 and Figure 11 As shown, the two sides of the cell carrier 5 each have a row of placement grooves 51 . The cell carrier 5 has an upper plane 50 . The inner sides of the placement grooves 51 have placement groove side walls 511 , placement groove bottom walls 512 and placement groove rear walls 513 .

[0031] Refer to the instruction manual Figures 1-11 A detection fixture for a battery cell carrier includes a workbench 1, on which a carrying mechanism 4 and a moving mechanism 2 are installed. The carrying mechanism 4 is used to carry the battery cell carrier 5, and a detection mechanism 3 is provided at the output end of the moving mechanism 2; the detection mechanism 3 includes a mounting frame 31 installed at the output end of the detection mechanism 3, a rotating frame 32 is installed on the mounting frame 31, a probe assembly 33 is provided on the front side of the rotating frame 32, and a driving member 34 is fixedly installed on the rear side of the probe assembly 33. A groove 341 is provided on one side of the driving member 34, and an insertion rod 342 is fixedly connected to the other side of the driving member 34. The insertion rod 342 is movably inserted into one end of the rotating frame 32, and an elastic component is sleeved on the outer side of the insertion rod 342. One 343, the two ends of the elastic component one 343 are fixedly connected to the driving component 34 and the rotating frame 32 respectively; a transmission component 35 is movably provided inside the groove 341, and a second insertion rod 351 is fixedly connected to one side of the transmission component 35, and the second insertion rod 351 is movably inserted into the other end of the rotating frame 32, and an elastic component two 352 is sleeved on the outer side of the second insertion rod 351, and the two ends of the elastic component two 352 are pressed against the rotating frame 32 and the transmission component 35 respectively, and a micrometer 36 is installed at the upper end of the rotating frame 32, and the transmission component 35 is used to push the probe of the micrometer 36 to move; during detection, the moving mechanism 2 drives the detection mechanism 3 to move, so that the probe assembly 33 moves along the side wall 511 of the placement groove and the bottom wall 512 of the placement groove.

[0032] In the above technical solution, if Figure 6 As shown, a fixed plate 353 is fixedly connected to the transmission member 35, and an inclined surface 354 is provided at the upper end of the fixed plate 353. The probe of the micrometer 36 is pressed on the surface of the inclined surface 354. A guide rod 321 is fixedly connected to the rotating frame 32, and the fixed plate 353 is sleeved on the guide rod 321. The guide rod 321 is arranged parallel to the insertion rod 351.

[0033] It should be noted that when the transmission member 35 is in motion, the inclined surface 354 can push the probe of the dial gauge 36 to move, so that the dial gauge 36 can detect the burr.

[0034] In the above technical solution, if Figure 4-Figure 6 As shown, the groove 341 is an ellipsoidal surface, and the surface shape of the transmission member 35 is adapted to the shape of the groove 341. The bottom of the groove 341 is the groove bottom 3411, and the side wall of the groove 341 is the groove side wall 3412. When the driving member 34 moves and rotates, it drives the transmission member 35 to move.

[0035] It should be noted that if Figure 5As shown, when the driving member 34 moves to the left, the groove bottom 3411 will push the transmission member 35 to move to the left. When the driving member 34 moves to the right, under the action of the elastic member 2 352, the transmission member 35 will move to the right. When the driving member 34 rotates, under the action of the groove side wall 3412, the transmission member 35 will be pushed to move to the left.

[0036] In this embodiment, the moving mechanism 2 can use a robotic arm or other device to drive the detection mechanism 3 to move. The elastic component 1 343 and the elastic component 2 352 are both compression springs. The probe assembly 33 has a probe body 332. During detection, the probe body 332 extends into the placement slot 51.

[0037] In this embodiment, the implementation method is as follows: in the initial state, Figure 11 As shown, the probe body 332 is tilted downward. When it is necessary to detect whether there are burrs on the placement groove side wall 511 in the placement groove 51, the detection mechanism 3 is driven to move by the moving mechanism 2, so that the probe body 332 extends into the placement groove 51 and contacts one of the placement groove side walls 511. Then the probe body 332 slides downward along the placement groove side wall 511. When encountering a burr, the probe body 332 will be pushed by the burr. At this time, the probe body 332 will drive the driving member 34 to move. When the driving member 34 moves, it drives the transmission member 35 to move. The transmission member 35 drives the probe of the micrometer 36 through the fixed plate 353 and the inclined surface 354. At this time, the micrometer 36 detects the burr. When the front end of the probe body 332 moves to the bottom of the placement groove side wall 511 and contacts the placement groove bottom wall 512, as shown in FIG. Figure 11 As shown, by moving the probe body 332 to the right by the moving mechanism 2, it is possible to detect whether there are burrs on the bottom wall 512 of the placement groove. When encountering burrs, the probe body 332 will swing upward, and the probe body 332 drives the driving member 34 to rotate, as shown in FIG. Figure 6 As shown, the driving member 34 can drive the transmission member 35 to move to the left through the groove side wall 3412, and finally the probe of the micrometer 36 is moved. At this time, the micrometer 36 detects the burr. Figure 11 As shown, the portion on the lower right side that was not detected when detecting the side wall 511 of the placement groove can also be detected together.

[0038] It should be noted that the width of the probe body 332 should be smaller than the width of the placement slot 51. This is to prevent the other side from affecting the probe body 332 when testing one side of the placement slot sidewall 511 in the placement slot 51. During the testing process, after testing one side of the placement slot sidewall 511, the other side of the placement slot sidewall 511 is tested. Similarly, after testing one side of the placement slot bottom wall 512, the other side of the placement slot bottom wall 512 is tested. The width of the probe body 332 should be greater than or equal to half the width of the placement slot 51. This is to ensure that the entire surface of the placement slot bottom wall 512 can be tested twice.

[0039] It should also be noted that, similar to detecting the bottom wall 512 of the placement groove, the probe body 332 can also detect whether there are burrs on the rear wall 513 of the placement groove.

[0040] The above technical solution sets a driving member 34 and a transmission member 35. During the detection process of the probe body 332, if there is any unevenness, whether it is the burrs on the side wall 511 of the placement groove pushing the probe body 332 to move, or the burrs on the bottom wall 512 of the placement groove pushing the probe body 332 to swing, it can be converted into the movement of the transmission member 35. The transmission member 35 is used to drive the micrometer 36 to move, thereby achieving the purpose of detecting the burrs, and a set of devices can perform detection at the same time.

[0041] Refer to the instruction manual Figure 3-Figure 11 The lower end of the rotating frame 32 is rotatably connected to the mounting frame 31 , and a power assembly 38 is installed on the mounting frame 31 , and the power assembly 38 is used to drive the rotating frame 32 to rotate.

[0042] It should be noted that the power assembly 38 includes a second motor 381 and a belt drive component 382. The second motor 381 is mounted on the mounting frame 31. The output end of the second motor 381 is connected to the rotating frame 32 via the belt drive component 382, ​​thereby driving the rotating frame 32 to rotate via the second motor 381. When the rotating frame 32 rotates, it can drive the various components mounted on the rotating frame 32 to rotate. The purpose is to enable the probe body 332 to switch between horizontal and tilted directions. When the probe body 332 is in a horizontal state, it can detect whether there are burrs on the upper surface 50 in the area of ​​the placement groove 51.

[0043] Refer to the instruction manual Figure 3-Figure 4 and Figure 7 The probe assembly 33 includes a slide rail 331, which is fixedly connected to the driving member 34. The probe body 332 is slidably connected to the inside of the slide rail 331. A moving drive assembly 37 is installed on the mounting frame 31 for driving the probe body 332 to slide back and forth inside the slide rail 331. The length direction of the probe body 332 is perpendicular to the axis of the insertion rod 342.

[0044] Furthermore, the mobile drive assembly 37 includes a motor 371 fixedly mounted on the mounting frame 31, a rocker 372 fixedly mounted on the output end of the motor 371, two push rods 373 are mounted on the end of the rocker 372 away from the motor 371, the probe body 332 is located between the two push rods 373, and the distance between the two push rods 373 is greater than the width of the probe body 332, so that the probe body 332 can move between the two push rods 373.

[0045] It should be noted that Figure 10 Taking a row of placement slots 51 on one side as an example, when the detection starts from the first placement slot 51 on the left, when the detection is close to the right side, since the detection mechanism 3 has a certain volume and occupies a certain space, the probe body 332 may not be inserted into the placement slot 51 on the right for detection. Therefore, the above technical solution adopts a method of making the probe body 332 movable in the slide rail 331. When detecting the placement slot 51 on the right, the probe body 332 is moved to the right, and when detecting the placement slot 51 on the left, the probe body 332 is moved to the left. Specifically, when moving, the rocker 372 is driven to swing by the motor 371, and the rocker 372 drives the probe body 332 to move through the push rod 373. The purpose of making the distance between the two push rods 373 greater than the width of the probe body 332 is to enable the probe body 332 to move freely when encountering burrs.

[0046] Furthermore, magnet 1 333 is fixedly installed at both ends of the slide rail 331, and magnet 2 334 is fixedly installed at one end of the probe body 332 located inside magnet 1 333. When magnet 2 334 is located at the end of the slide rail 331, it is adsorbed and fixed to magnet 1 333.

[0047] It should be noted that, due to the mutual adsorption and fixation between the first magnet 333 and the second magnet 334 , when the probe body 332 encounters a burr, no relative movement occurs between the probe body 332 and the slide rail 331 .

[0048] Refer to the instruction manual Figure 1-Figure 2 and Figure 8 The carrying mechanism 4 includes a turntable 41 and a motor 42. The motor 42 is used to drive the turntable 41 to rotate. A clamping component is provided on the turntable 41, and the clamping component is used to clamp the battery cell carrier 5.

[0049] Furthermore, the clamping component includes a fixed block 43, a clamping block 44 and a fastening bolt 46. A number of mounting grooves 411 are provided on the turntable 41. A fixed block 43 is provided at both ends of each mounting groove 411. A clamping block 44 is slidably provided on the inclined surface on the opposite side of the two fixed blocks 43. A long groove 45 is provided on the upper surface of the clamping block 44. The fastening bolt 46 is threadedly connected to the fixed block 43 from the position of the long groove 45, so that the fastening bolt 46 presses the clamping block 44 onto the fixed block 43.

[0050] It should be noted that when clamping the cell carrier 5, the cell carrier 5 is placed between the clamping blocks 44 on both sides. Then, the tightening bolts 46 are tightened. Under the action of the tightening bolts 46, the clamping blocks 44 slide down the inclined surface of the fixing block 43. Once the clamping blocks 44 clamp the cell carrier 5, they no longer move. After testing one row of placement slots 51, the motor 3 42 drives the turntable 41 to rotate, and the placement slots 51 on the other side are rotated to the bottom of the detection mechanism 3 for testing.

[0051] Refer to the instruction manual Figure 1 and Figure 2 A cylinder three 10 is installed on the workbench 1, and the moving mechanism 2 includes a fixed frame 21 fixedly installed on the output end of the cylinder three 10, a guide rod 22 is fixedly installed on the fixed frame 21, a slider 23 is slidably installed on the guide rod 22, a cylinder one 24 is fixedly installed on the slider 23, the output end of the cylinder one 24 is installed on the guide rod 22, a cylinder two 25 is vertically installed on the slider 23, and the output end of the cylinder two 25 is fixedly installed on the mounting frame 31.

[0052] It should be noted that cylinder three 10 is used to drive the moving mechanism 2 to move forward and backward, cylinder one 24 is used to drive the slider 23 to move back and forth on the guide rod 22, and cylinder two 25 is used to drive the detection mechanism 3 to move vertically.

[0053] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
