[0033] The battery cell detection clamping and moving device of the application has compact structure, is stable and reliable, is convenient and fast to use, has high automation degree, and can improve the detection efficiency and detection precision of the battery cell 100. The battery cell 100 can be driven to stably and reliably slide in a straight line through the sliding module. The battery cell 100 can be driven to stably and reliably rotate through the rotating platform 10. The two groups of vertical sides of the battery cell 100 can be stably and effectively clamped through the clamping device, and the clamping device has high compatibility and can clamp battery cells of different sizes. The clamping device includes the lower mounting plate 21, the middle mounting plate 22 and the upper mounting plate 23 which are horizontally and spacedly arranged from bottom to top, can reserve compact installation space for the first clamping device and the second clamping device, and ensure effective clamping of the two groups of vertical sides of the battery cell 100.

[0034] The sliding module includes the bottom plate 30, the linear module 31 and the guide rail 32 installed on the bottom plate 30, and the guide rail 32 is parallel to the slide rail of the linear module 31. The linear module 31 is a general synchronous belt linear motion module in the technical field, which is not limited specifically herein, can realize stable and effective linear sliding, and improve the sliding displacement precision of the battery cell.

[0035] The sliding module further includes a sliding base which is a symmetrical integral piece. The sliding base includes two L-shaped base plates 33 arranged oppositely, and a connecting base plate 34 connected between the end portions of the two L-shaped base plates 33. The two L-shaped base plates 33 form a cavity for installing the rotating platform 10.

[0036] The bottoms of the two L-shaped base plates 33 are respectively fixed on the sliders of the linear module 31 and the guide rail 32. The linear module 31 can drive the sliding base to stably and effectively slide in a straight line along the slide rail of the linear module 31 and the guide rail 32.

[0037] Specifically, the L-shaped base plate 33 includes a vertical base plate and a horizontal base plate fixed perpendicularly at the bottom of the vertical base plate. The horizontal base plate is fixedly connected to the slider. The specific fixed connection mode can be a general fixed connection mode in the technical field, which is not limited specifically herein.

[0038] In addition, the bottom plate 30 is installed with a grating ruler 35. The reading head on the grating ruler is installed on the sliding base. The position information of the sliding base can be tracked and fed back in real time through the grating ruler 35, so that the position information of the clamping device and the battery cell can be fed back in real time, the clamping device and the battery cell can stably slide in a straight line, and the displacement precision and detection precision of the battery cell 100 are improved.

[0039] The rotating platform 10 is installed in the cavity between the two L-shaped base plates 33. The specific installation and connection mode can be a general connection mode in the technical field, which is not limited specifically herein.

[0040] The rotating platform 10 and the lower mounting plate 21 are fixedly positioned by positioning pins, so that the clamping device can be stably and firmly positioned and mounted on the rotating platform 10, ensuring that the rotating platform 10 can drive the clamping device to rotate smoothly and effectively, and ensuring the accuracy of rotating the battery cell 100 into position and the detection accuracy.

[0041] The rotating platform 10 can be a hollow rotating platform commonly used in the technical field, which is driven to rotate by a servo motor, which is not specifically limited here. The hollow rotating platform has the advantages of high torque and rigidity, high precision, high transmission efficiency, simple installation, etc., which is conducive to ensuring the assembly process precision, ensuring the accuracy of rotating the battery cell 100 into position, and improving the detection accuracy.

[0042] The rotating platform 10 is provided with a slot-shaped photoelectric sensor, and the slot-shaped photoelectric sensor and the servo motor of the rotating platform 10 are connected with the PLC control system.

[0043] In the initial position, the rotating platform 10 is in the first detection position, which can make the two first side surfaces 101 on the battery cell 100 correspond to the two side line-scan laser sensors of the detection mechanism, respectively. When the rotating platform 90 rotates 90° from the first detection position to the second detection position, it can make the two second side surfaces 102 on the battery cell 100 correspond to the two side line-scan laser sensors of the detection mechanism, respectively. After the rotating platform 90 rotates 90° from the first detection position to the second detection position, the slot-shaped photoelectric sensor on the rotating platform 10 can sense that the rotating platform 10 rotates to the second detection position. At this time, the slot-shaped photoelectric sensor sends a signal to the PLC control system, and the PLC control system controls the servo motor to stop moving, so that the rotating platform 10 can be positioned on the second detection position, so that the two side line-scan laser sensors can stably and effectively detect the size and flatness of the two first side surfaces 101 and the two second side surfaces 102 on the battery cell 100.

[0044] As shown in Figures 4-5 The first clamping device includes a first forward and reverse screw 41 mounted on the lower mounting plate 21, and two first nut seats 42 respectively mounted at both ends of the first forward and reverse screw 41, and the first clamping mechanism 43 is connected to the two first nut seats 42, respectively.

[0045] The first clamping mechanism 43 includes two vertically arranged first transition plates 431, the inner sides of the two first transition plates 431 are located in the same plane, and the inner sides of the two first transition plates 431 are respectively connected with first clamping jaws 432 which can slide up and down, and the first clamping jaws 432 on the two first clamping mechanisms 43 are arranged one by one corresponding to each other.

[0046] The clamping surface of the first clamping jaw 432 is provided with a polyether ether ketone protective plate, which can protect the battery cell 100.

[0047] Through rotation of the first reversible screw 41, the two first nut blocks 42 can be driven to slide relative to or away from each other along the first reversible screw 41. When the two first nut blocks 42 slide relative to each other, the distance between the first clamping jaws 432 on the two first clamping mechanisms 43 decreases, so that the two corresponding first side surfaces 101 of the battery cell 100 can be clamped; when the two first nut blocks 42 slide away from each other, the distance between the first clamping jaws 432 on the two first clamping mechanisms 43 increases, so that the clamping of the battery cell 100 is released.

[0048] In this embodiment, the two first transition plates 431 are connected with a first air cylinder 433, which is used to drive the first clamping jaws 432 to slide up and down. The inner side surface of the first transition plate 431 is provided with a first vertical slide, and the first clamping jaw 432 slides up and down along the first slide.

[0049] The lower mounting plate 31 is provided with two first slide rails 44, which are respectively arranged parallel to the two sides of the first reversible screw 41; the first nut block 42 is connected with a connecting seat 421 for mounting the first clamping mechanism 43, and the two sides of the connecting seat 421 slide along the two first slide rails 44, respectively, to ensure that the connecting seat 421 and the first clamping mechanism 43 can slide smoothly and effectively.

[0050] The two first transition plates 431 are respectively fixedly connected to the two sides of the connecting seat 421. The specific fixing connection mode can be a common connection mode in the technical field, which is not limited here.

[0051] The first clamping device further comprises a first motor 45 mounted on the middle mounting plate 22, and a first synchronous belt 46 is connected between the output shaft of the first motor 45 and the bearing seat 411 at the end of the first reversible screw 41. The first motor 45 is used to drive the first synchronous belt 46 to rotate, so as to drive the first reversible screw 41 to rotate, and through the rotation of the first reversible screw 41, the two first nut blocks 42 can be driven to slide relative to or away from each other along the first reversible screw 41.

[0052] In addition, the lower mounting plate 21 is provided with a clamping-in-place photoelectric sensor and a loosening-in-place photoelectric sensor (not shown in the figure). The clamping-in-place photoelectric sensor can sense the clamping-in-place state of the first clamping mechanism to the first side surface 101 of the battery cell 100 and send a signal to the first motor 45, so that the first motor 45 stops rotating, thereby enabling the first clamping mechanism to maintain the clamping-in-place state. Thus, the battery cell 100 can be accurately and effectively clamped, so that the battery cell 100 can be smoothly and effectively slid and rotated, the sliding and rotating precision is improved, and the detection precision is further improved. When the first clamping mechanism moves to a certain position, the battery cell 100 is loosened and no longer clamped. At this time, the first clamping mechanism is in a loosening-in-place state. The loosening-in-place photoelectric sensor can sense the loosening-in-place state of the first clamping mechanism and send a signal to the first motor 45. The first motor 45 stops rotating, thereby enabling the first clamping mechanism to maintain the loosening-in-place state.

[0053] As shown in Figures 6-7 The second clamping device includes a second forward and reverse lead screw 51 mounted on the middle mounting plate 22, and two second nut seats 52 mounted at both ends of the second forward and reverse lead screw 51, respectively. The two second nut seats 52 are respectively connected with a second clamping mechanism 53. The second clamping mechanism 53 includes a second transition plate 531 arranged vertically, and a second clamping jaw 532 connected to the second transition plate 531 and capable of sliding up and down. The second clamping jaws 532 on the two second clamping mechanisms 53 are oppositely arranged.

[0054] The clamping surface of the second clamping jaw 532 is provided with a polyether ether ketone protective plate, which can protect the battery cell 100.

[0055] The second transition plate 531 is connected with a second air cylinder 533, which is used to drive the second clamping jaw 532 to slide up and down.

[0056] The two second nut seats 52 can slide relative to each other or in opposite directions along the second forward and reverse lead screw 51. When the two second nut seats 52 slide relative to each other, the distance between the second clamping jaws 532 on the two second clamping mechanisms 53 becomes smaller, thereby clamping the two corresponding second side surfaces 102 of the battery cell 100. When the two second nut seats 52 slide in opposite directions, the distance between the second clamping jaws 532 on the two second clamping mechanisms 53 becomes larger, thereby releasing the clamping of the battery cell 100.

[0057] The second clamping device further comprises a second motor 54 installed on the middle mounting plate 22, a second synchronous belt 55 is connected between the output shaft of the second motor 54 and the bearing seat at the end of the second lead screw 51, the second motor 54 is used to drive the second synchronous belt 55 to rotate, so as to drive the second lead screw 51 to rotate. The rotation of the second lead screw 51 can drive the two second nut seats 52 to slide relative to or away from the second lead screw 51.

[0058] In addition, the middle mounting plate 22 is provided with two second sliding rails 56, and the two second nut seats 52 slide along the two second sliding rails 56 respectively, so as to ensure that the second nut seats 52 and the second clamping mechanism 53 can slide smoothly and effectively. In addition, the middle mounting plate 22 is provided with a clamping-in-place photoelectric sensor 57 and a loosening-in-place photoelectric sensor 58, the clamping-in-place photoelectric sensor 57 can sense the clamping-in-place state of the second side 102 of the battery cell 100 clamped by the second clamping mechanism, and send a signal to the second motor 54, so that the second motor 54 stops rotating, so that the second clamping mechanism can maintain the clamping-in-place state; so as to accurately and effectively clamp the battery cell 100, so that the battery cell 100 can slide and rotate smoothly and effectively, improve the sliding and rotating precision, and further improve the detection precision. When the second clamping mechanism moves to a certain position, the battery cell 100 can be loosened and no longer clamped, at this time, the second clamping mechanism is in a loosening-in-place state, the loosening-in-place photoelectric sensor 58 can sense the loosening-in-place state of the second clamping mechanism, and send a signal to the second motor 54, so that the second motor 54 stops rotating, so that the second clamping mechanism can maintain the loosening-in-place state.

[0059] The length directions of the first lead screw 41 and the second lead screw 51 are perpendicular to each other, so the moving directions of the first clamping jaw 432 and the second clamping jaw 532 are perpendicular to each other, so that the first clamping jaw 432 and the second clamping jaw 532 can clamp the perpendicular sides of the battery cell 100. The first side 101 of the battery cell 100 is perpendicular to the second side 102, and the two groups of first clamping jaws 432 can clamp the two first sides 101 respectively, and the two second clamping jaws 532 can clamp the two second sides 102 respectively.

[0060] As Figure 8 and Figure 9As shown, the upper mounting plate 23 is provided with four first sliding grooves 231 and two second sliding grooves 232, the four first sliding grooves 231 are arranged in a two-row two-column symmetrical structure, the two second sliding grooves 232 are located on the same straight line, and the two second sliding grooves 232 are symmetrically arranged on the two sides of the symmetrical structure formed by the four first sliding grooves 231; the length direction of the first sliding groove 231 is perpendicular to the length direction of the second sliding groove 232, and the first sliding groove 231 and the second sliding groove 232 are arranged in perpendicular intersection; the intersection position of the first sliding groove 231 and the second sliding groove 232 is provided with an adaptive plate 233, the battery cell 100 is placed on the adaptive plate 233, and the adaptive plate 233 is adapted to the bottom surface of the battery cell 100, so that the battery cell 100 can be stably and effectively placed on the upper mounting plate 23.

[0061] The four first clamping jaws 432 on the first clamping mechanism 43 are respectively slidably fitted in the four first sliding grooves 231, so that the first clamping jaw 432 can stably and effectively slide, thereby ensuring that the first clamping jaw 432 can stably and effectively clamp the battery cell 100. The two second clamping jaws 532 are slidably fitted in the two second sliding grooves 232, so that the second clamping jaw 532 can stably and effectively slide, thereby ensuring that the second clamping jaw 532 can stably and effectively clamp the battery cell 100.

[0062] As shown in the figure, Figure 9 The middle mounting plate 22 is provided with four third sliding grooves 221, and the four third sliding grooves 221 correspond one by one to the four first sliding grooves 231; the length direction of the four third sliding grooves 221 is perpendicular to the length direction of the second lead screw 51, and two of the third sliding grooves 221 are located on one side of the second lead screw 51, and the other two third sliding grooves 221 are located on the other side of the second lead screw 51.

[0063] The first transition plate 431 on the first clamping mechanism 43 extends out of the third sliding groove 221 and slides along the third sliding groove 221, so that the first clamping jaw 432 can stably and effectively slide, thereby ensuring that the first clamping jaw 432 can stably and effectively clamp the battery cell 100.

[0064] The lower mounting plate 21 and the middle mounting plate 22, and the middle mounting plate 22 and the upper mounting plate 23 are vertically connected with a plurality of prisms, and the specific connection mode can be a general connection mode in the technical field, which is not limited here. The prisms can make the lower mounting plate 21, the middle mounting plate 22 and the upper mounting plate 23 horizontally and spaced from bottom to top, can reserve a compact installation space for the first clamping device and the second clamping device, and ensure effective clamping of the two groups of vertical sides of the battery cell 100.

[0065] The operation process of the battery cell detection clamping and moving device of the application comprises:

[0066] Clamping the battery cell 100: the first motor 45 drives the first screw rod 41 to rotate, so that the two first nut seats 42 move relative to each other, thereby driving the two first clamping mechanisms to move relative to each other, so that the distance between the first clamping jaws 431 on the two first clamping mechanisms becomes smaller, thereby clamping the two first side surfaces 101 of the battery cell 100. When the first clamping mechanism is clamped to the first side surface 101, the clamping-to-position photoelectric sensor can sense the clamping-to-position state of the first clamping mechanism and send a signal to the first motor 45, so that the first motor 45 stops rotating, thereby maintaining the clamped-to-position state of the first clamping mechanism. The second motor 54 drives the second screw rod 51 to rotate, so that the two second nut seats 52 move relative to each other, thereby driving the two second clamping mechanisms to move relative to each other, so that the distance between the second clamping jaws 531 on the two second clamping mechanisms becomes smaller, thereby clamping the two second side surfaces 102 of the battery cell 100. When the second clamping mechanism is clamped to the first side surface 102, the clamping-to-position photoelectric sensor 57 can sense the clamping-to-position state of the second clamping mechanism and send a signal to the second motor 54, so that the first motor 54 stops rotating, thereby maintaining the clamped-to-position state of the second clamping mechanism.

[0067] The linear module 31 drives the clamping device and the battery cell 100 to move stably and accurately to the first specified position, at which the rotating platform 10, the clamping device and the battery cell 100 are just at the first detection position, and the two first side surfaces 101 on the battery cell 100 correspond to the two side line-scan laser sensors of the detection mechanism respectively.
