Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For example, see Figure 1-Figure 11 The present invention discloses a cell thickness detection device for a solar photovoltaic component production line, comprising a processing table 1, a resistance plate 2 is fixedly installed at one end of the processing table 1, a hydraulic rod 3 is installed at the other end of the processing table 1, a sliding plate 4 is arranged at the power output end of the hydraulic rod 3, the sliding plate 4 is slidably connected to the processing table 1, a supporting assembly 5 is arranged on one side of the sliding plate 4, the supporting assembly 5 comprises a first slider 51, a second slider 52, and a third slider 53 which are slidably connected to the sliding plate 4, a limiting block 6 is arranged on the other side of the sliding plate 4, the limiting block 6 is fixedly installed on the processing table 1, a first detection head 11 is installed on the limiting block 6, the first detection head 11 is used to detect the thickness of a single cell 7, a second detection head 12 is arranged on one side of the first detection head 11, and the second detection head 12 is used to detect the thickness of the cell 7 stacked together.

[0031] When the existing battery cell 7 thickness detection device detects the thickness of the battery cell 7, due to various uncertain factors and production complexity in the production process of the battery cell 7, the thickness of different positions of the same battery cell 7 may be different, because the raw materials and cutting processes may cause the thickness of the battery cell 7 to be uneven after production, and the existing detection equipment can only detect a fixed point of the battery cell 7, and the detection of the thickness of the battery cell 7 is not comprehensive enough, which may affect the subsequent processing of the battery cell 7; the equipment can, during the detection of a single battery cell 7, enable the battery cell 7 to move in a wave-like manner through the supporting component 5, so that the first detection head 11 can detect multiple positions of the battery cell 7, so that the first detection head 11 can detect the battery cell 7 more comprehensively, which is beneficial to the subsequent processing of the battery cell 7 and ensures that the thickness of the battery cell 7 meets the production standards.

[0032] Through the combined design of the first detection head 11 and the second detection head 12, the thickness of a single battery cell 7 and the thickness of multiple battery cells 7 stacked together can be separately detected, so that the device can timely discover and remove battery cells 7 that do not meet the thickness standards, ensuring the smooth progress of subsequent processes and the quality of the final product; at the same time, Figure 1The first detection head 11 and the second detection head 12 shown are provided with matching detection heads on the processing table 1, and the thickness of the battery cell 7 is detected by the cooperation of the detection heads on both sides; the design of the whole structure is to simplify the operation process, reduce manual intervention, and significantly improve the processing and detection efficiency of the battery cell 7 through automation and precise control.

[0036] A sliding column 517 is provided on one side of the first slider 51 and the second slider 52, and a sliding groove 57 is provided on the second slider 52 and the third slider 53. The sliding column 517 on the first slider 51 is slidably connected with the sliding groove 57 on the second slider 52, and the sliding column 517 on the second slider 52 is slidably connected with the sliding groove 57 on the third slider 53.

[0037] The sliding column 517 on the first slider 51 is provided with a groove 518, and an adjustment plate 512 is provided at one end of the sliding groove 57. The adjustment plate 512 is slidably connected to the second slider 52 and the third slider 53 respectively. A second spring 513 is provided on one side of the adjustment plate 512, and one end of the second spring 513 is installed in the second slider 52 and the third slider 53 respectively.

[0038] The second slider 52 is internally slidably connected with a limiting bevel block 58, which is used for being slidably connected with the groove 518. A slope groove 59 is provided on the limiting bevel block 58, and the inclined surface of the slope groove 59 abuts against a resistance rod 511. The resistance rod 511 is internally slidably connected with the second slider 52. A first spring 510 is provided at one end of the limiting bevel block 58, and one end of the first spring 510 is installed in the second slider 52.

[0039] A round rod 514 is fixedly connected to one side of the third slider 53, and a round tube 515 is slidably connected to the round rod 514. A protrusion 519 is provided on one side of the round tube 515, and the protrusion 519 is slidably connected to the smooth groove 46. A third spring 516 is provided on one side of the protrusion 519, and the third spring 516 is located in the sliding plate 4.

[0040] The limiting block 6 is provided with a plurality of straight slide grooves 61 and wave slide grooves 62 . The straight slide grooves 61 are connected with the wave slide grooves 62 . The sliding balls 56 are used for sliding connection with the straight slide grooves 61 and the wave slide grooves 62 .

[0041] First, the battery cells 7 are placed on each supporting tray 54. The supporting tray 54 is provided with an adsorption mechanism for adsorbing the battery cells 7. The adsorption mechanism is a prior art and can prevent the battery cells 7 from being offset during operation of the equipment. Then, the hydraulic rod 3 is started to drive the sliding plate 4 to slide on the processing table 1. The sliding of the sliding plate 4 drives the first slider 51, the second slider 52, and the third slider 53 to move together. The first slider 51, the second slider 52, and the third slider 53 will not be separated from the sliding plate 4. In the process of driving the sliding plate 4 to slide on the processing table 1 by the hydraulic rod 3, the third slider 53 on the sliding plate 4 and the supporting tray 54 on the third slider 53 are moved to the first detection head 11. At this time, the sliding ball 56 on the third slider 53 slides from the straight slide groove 61 into the wave slide groove 62. The design of the wave slide groove 62 allows the sliding ball 56 to slide in the straight slide groove 61. When sliding in the wave slide groove 62, it can drive the sliding rod 55 and the supporting tray 54 to move in a wave-like manner. At the same time, each slider corresponds to a sliding rod 55, and each sliding rod 55 passes through each slider respectively. The sliding rod 55 is slidably connected to the slider, so that the battery cell 7 on the supporting tray 54 can move with the supporting tray 54, so that the first detection head 11 can detect multiple locations of the battery cell 7, so that the first detection head 11 can collect more data on the thickness of the battery cell 7, so that the thickness detection of the battery cell 7 is more accurate; with the push of the hydraulic rod 3, the subsequent second slider 52 and the first slider 51 pass under the first detection head 11 in turn, and at the same time, the second slider 52 and the first slider 51 are also correspondingly provided with corresponding straight slide grooves 61 and wave slide grooves 62, so that the first detection head 11 can detect the thickness of the battery cell 7 on the second slider 52 and the first slider 51 supporting tray 54.

[0042] As the hydraulic rod 3 is continuously driven, when the sliding plate 4 drives the third slider 53 to slide to the contact plate 2, the bearing tray 54 on the third slider 53 contacts the contact plate 2. As the sliding plate 4 continues to slide, the round rod 514 on one side of the third slider 53 slides in the smooth groove 46 along with the raised block 519 on the round tube 515. During the sliding process of the raised block 519, the third spring 516 is contacted, causing the third spring 516 to deform, providing power for subsequent recovery. At the same time, the design of the third spring 516 ensures that there is always a force that can support the third slider 53, so that the third slider 53 can pass through the second The sliding column 517 on the slider 52 pulls the second slider 52. When the second slider 52 is pulled, the second slider 52 can pull the first slider 51 through the sliding column 517 on the first slider 51. At the same time, the length of the third slide groove 43 is greater than the second slide groove 42, and the length of the second slide groove 42 is greater than the first slide groove 41. Under the action of the third spring 516, the positions of the first slider 51, the second slider 52, and the third slider 53 are staggered, so that the interval between the first slider 51, the second slider 52, and the third slider 53 is maintained at the maximum state, providing sufficient detection space for the battery cells 7 on each slider.

[0043] When the sliding plate 4 drives each slider to move together, the supporting tray 54 on the third slider 53 first contacts the contact plate 2. When the supporting tray 54 on the third slider 53 contacts the contact plate 2, as the hydraulic rod 3 continues to drive the sliding plate 4, the third slider 53 slides in the third sliding groove 43, and at the same time, the sliding column 517 on the second slider 52 slides in the sliding groove 57 of the third slider 53. When the battery cell 7 of the supporting tray 54 on the second slider 52 is detected, as the hydraulic rod 3 continues to push, the supporting tray 54 on the second slider 52 makes the contact rod 511 contact the contact plate 2 before contacting the contact plate 2, so that the contact rod 511 slides into the second slider 52. While the contact rod 511 slides, it contacts the inclined groove 59 on the limiting inclined block 58, so that the limiting inclined block 58 slides downward, and while the limiting inclined block 58 slides, The first spring 510 is deformed and the sliding of the limiting bevel 58 is restricted so that the limiting bevel 58 slides out of the groove 518, so that the limiting bevel 58 releases the restriction on the sliding column 517 on the first slider 51, so that the first slider 51 can move normally. With such a design, the first slider 51 can move only after the first detection head 11 completes the detection of the battery cell 7 on the tray 54 of the second slider 52. With such a design, when the first detection head 11 detects the battery cell 7 on the tray 54 of the second slider 52, the first slider 51 will not be offset, which can prevent the tray 54 on the first slider 51 from affecting the detection of the thickness of the battery cell 7 on the tray 54 of the second slider 52 by the first detection head 11, so that the trays 54 on each slider can pass under the first detection head 11 in turn, and the overlap of the trays 54 is prevented.

[0044] As the hydraulic rod 3 continues to push the sliding plate 4, when the battery cell 7 on the first slider 51 supporting tray 54 also passes the first detection head 11, the hydraulic rod 3 continues to push the sliding plate 4. At this time, the supporting trays 54 on each slider all contact with the contact plate 2, so that the sliding column 517 on the first slider 51 slides to the adjustment plate 512 on the second slider 52, and at the same time, the sliding column 517 on the second slider 52 slides to the adjustment plate 512 on the first slider 51. As the hydraulic rod 3 continues to push, the first slider 51 slides from the first slide groove 41 into the lower inclined groove 44, and at the same time, the third slider 53 slides from the third slide groove 43 into the upper inclined groove 45. This design makes the first slider 51 approach one side of the second slider 52 under the action of the lower inclined groove 44, and at the same time, the third slider 53 approaches the other side of the second slider 52 under the action of the upper inclined groove 45. Through this design, each slider The support tray 54 and the battery cells 7 can be stacked tightly together. At the same time, during the stacking process, the sliding column 517 on the first slider 51 will squeeze the adjustment plate 512 on the second slider 52, and the sliding column 517 on the second slider 52 will squeeze the adjustment plate 512 on the third slider 53. The second spring 513 will be deformed while being squeezed. The design of the second spring 513 can provide power for the resetting of the adjustment plate 512. The design of the adjustment plate 512 can provide a relatively adjustable distance between each slider and the support tray 54 to prevent the battery cells 7 from being damaged due to excessive force when the sliders approach each other. At the same time, the battery cells 7 on each support tray 54 can be in close contact. The thickness of the stacked battery cells 7 is detected by the second detection head 12, and then the system of the second detection head 12 will automatically subtract the thickness of each support tray 54 to obtain the thickness of the stacked battery cells 7.

[0045] When the third slider 53 slides from the third slide groove 43 into the upper inclined groove 45, the third slider 53 will drive the round rod 514 and the round tube 515 to slide, so that the round rod 514 can always move with the third slider 53. Through such a design, the third spring 516 can always act on the third slider 53, so that after the thickness of a single battery cell 7 and the thickness of the battery cell 7 after stacking are detected, when the hydraulic rod 3 pulls the sliding plate 4 to slide back, the third spring 516 can push the third slider 53 to slide through the round tube 515 and the round rod 514. At this time, since the sliding column 517 of the first slider 51 is stuck in the second slider 52, and the sliding column 517 of the second slider 52 is stuck in the third slider 53, the third slider 53 slides and drives the second slider 52 and the first slider 51 to slide together, so that each sliding column 517 is disengaged from the clamping of each slider, and at the same time, each adjustment plate 512 is restored under the action of the second spring 513 When the first slider 51 is in the original position, the third spring 516 is used to pull the third slider 53 and the second slider 52, so that the sliding post 517 on the first slider 51 slides to the limiting inclined block 58, and the first slider 51 has slid to the rightmost end of the first slide groove 41 and can no longer move. At the same time, the third spring 516 is still pulling the third slider 53 and the second slider 52, so that the sliding post 517 on the first slider 51 slides to the inclined surface of the limiting inclined block 58, and through the resistance to the inclined surface of the limiting inclined block 58, the limiting inclined block 58 slides into the second slider 52, and when it slides to the groove 518 on the sliding post 517, the limiting inclined block 58 is clamped again by the second spring 513.

[0046] At the same time, each slider corresponds to a smooth groove 46 and a third spring 516. This design can assist each slider to return to its original position, and can also prevent the position of other sliders from being offset when the battery cell 7 on the slider is detected, thereby preventing the subsequent detection from being affected. At the same time, when the resistance rod 511 on the second slider 52 is resisted by the resistance plate 2 into the second slider 52, as the hydraulic rod 3 continues to drive the sliding plate 4, the second slider 52 will resist the corresponding third spring 516 to produce deformation. At the same time, Figure 8 The first sliding block 51 is also provided with a round rod 514 and a round tube 515 structure which is the same as that of the third sliding block 53 .

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
