For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] The specific structure of the battery sealing size detection device of the embodiment of the present application is described below with reference to the accompanying drawings. Figures 1-4 The specific structure of the battery sealing size detection device of the embodiment of the present application is described below with reference to the accompanying drawings.

[0028] The present application discloses a kind of battery sealing size detection device, such as Figures 1-3As shown, the battery sealing size detection device includes a support 1, an image detection module 2, a reference part 3 and a driving mechanism 4. The support 1 is provided with a test platform 5, and the test platform 5 is provided with a matching hole. The test platform 5 is used for placing a battery 7. The image detection module 2 includes a transmitting part 21 and a receiving part 22. The transmitting part 21 and the receiving part 22 are located on the test platform 5 and at two sides of the test platform 5. The reference part 3 is arranged on the test platform 5. The driving mechanism 4 is provided with a power output end which penetrates through the test platform 5 and can abut against the bottom wall of the battery 7 to drive the battery 7 to separate from the test platform 5 and rotate relative to the test platform 5. It can be understood that the test platform 5 is provided with a matching hole 51 which is smaller than the size of the battery 7. In the actual working process, the battery 7 is placed at the position of the test platform 5 provided with the matching hole 51 so that the battery 7 covers the matching hole 51. The transmitting part 21 of the image detection module 2 emits light to the battery 7 and the reference part 3, and the receiving part 22 receives the projection of the battery 7 and the reference part 3. The size of the reference part 3 is used for reference, and the sealing size of the battery 7 is obtained. Specifically, since the size of the reference part 3 is known, after the receiving part 22 receives the projection of the reference part 3 in the test process, the actual size and the projection size can be obtained according to the size and the projection size of the reference part 3, and then the sealing size of the battery 7 can be obtained according to the ratio. After the first measurement is completed, the driving mechanism 4 is started, the power output end of the driving mechanism 4 can rise in the matching hole 51, so that the power output end can abut against the bottom wall of the battery 7 to make the battery 7 separate from the test platform 5. Then the power output end rotates to make the battery 7 rotate by an angle relative to the test platform 5. Then the power output end descends in the matching hole 51 to make the power output end separate from the battery 7 and make the battery 7 return to the test platform. Then the image detection module 2 can be tested again (the specific test process is the same as the first test process). According to the test results of two times, the sealing size of the battery 7 can be obtained, the test misjudgment rate is reduced, and the probability of unqualified products mixed into qualified products is reduced.

[0029] In some embodiments, as Figure 1 and Figure 3As shown, the driving mechanism 4 comprises a jig 41, a driving support 42, a first driving member 43 and a second driving member 44. The jig 41 is fitted in the fitting hole 51 of the test platform 5 to form a power output end of the driving mechanism 4. The driving support 42 is arranged in the bracket 1. The first driving member 43 is arranged on the driving support 42. The second driving member 44 is connected with the first driving member 43 and can move in the vertical direction under the driving of the first driving member 43. The second driving member 44 is connected with the jig 41 to drive the jig 41 to rotate. It can be understood that the jig 41 arranged separately as the power output end of the driving mechanism 4 ensures that the battery 7 can be stably contacted, driven to be separated from the test platform 5 and rotated relative to the test platform 5 during the working process of the driving mechanism 4. The driving support 42 arranged separately for supporting other components of the driving mechanism 4 can reduce the stress of the bracket 1 compared with arranging the driving mechanism 4 directly on the bracket 1, thereby avoiding the phenomenon that the bracket 1 is bent under stress and adversely affects the normal measurement of the image detection module 2. The first driving member 43 can drive the second driving member 44 to move vertically, realizing the vertical movement of the jig 41. The second driving member 44 drives the jig 41 to rotate. The driving mechanism 4 is divided into the first driving member 43 and the second driving member 44, avoiding the use of a mechanical arm with complex structure and high cost to realize the lifting and rotation of the jig 41, simplifying the structure of the driving mechanism 4 and reducing the manufacturing cost of the driving mechanism 4.

[0030] In some specific embodiments, as shown in Figure 2 As shown, the first driving member 43 comprises a cylinder 431 and a first driving seat 432. The cylinder body 4311 of the cylinder 431 is installed on the driving support 42. The first driving seat 432 is connected with the piston rod 4312 of the cylinder 431 and the second driving member 44. It can be understood that compared with connecting the piston rod 4312 of the cylinder 431 with the second driving member 44, using the first driving seat 432 as an intermediate connecting component improves the connection stability of the first driving member 43 and the second driving member 44, thereby ensuring that the first driving member 43 can stably drive the second driving member 44 to lift.

[0031] In some more specific embodiments, as shown in Figure 3As shown, the first driving base 432 is provided with a matching groove 4321, and the inner side wall of the matching groove 4321 is provided with a clamping protrusion 4322. The piston rod 4312 is matched in the matching groove 4321, and the piston rod 4312 is provided with a clamping groove 43121 matched with the clamping protrusion 4322. Thus, in the assembly process, the free end of the piston is directly inserted into the matching groove 4321, and the clamping protrusion 4322 is clamped into the clamping groove 43121. This can not only ensure the stability of the connection between the first driving base 432 and the piston rod 4312, thereby ensuring that the cylinder 431 can stably drive the first driving base 432 to rise and fall, but also facilitate the connection between the first driving base 432 and the piston rod 4312, thereby facilitating the assembly of the battery sealing size detection device.

[0032] Of course, it should be additionally noted here that in other embodiments of the present application, the first driving member 43 can select an electric push rod, a motor-driven ball screw, or a motor-driven gear rack and other linear driving mechanisms according to actual needs, and is not limited to the cylinder 431 of the present embodiment.

[0033] In some specific embodiments, as shown in Figure 3 As shown, the second driving member 44 includes a second driving base 441 and a driving motor 442. The second driving base 441 is connected to the first driving member 43, and the driving motor 442 is arranged on the second driving base 441. The motor shaft of the driving motor 442 is connected to the jig 41. It can be understood that the second driving base 441 can stably support the driving motor 442, thereby ensuring that the first driving member 43 can stably drive the second driving member 44 to rise and fall.

[0034] In some more specific embodiments, as shown in Figure 4 As shown, the second driving base 441 includes two horizontally arranged horizontal portions 4411 and a vertical portion 4412. The two ends of the vertical portion 4412 are respectively connected to the two horizontal portions 4411. The driving motor 442 is arranged on one of the horizontal portions 4411. One end of the jig 41 is inserted into the other horizontal portion 4411 and extends out of the horizontal portion 4411. The end of the jig 41 extending out of the horizontal portion 4411 is connected to the driving shaft of the driving motor 442 through a shaft coupling 443. It can be understood that the second driving base 441 is formed as a U-shaped plate. On the one hand, it can ensure the stable connection between the second driving base 441 and the first driving member 43. On the other hand, it can stably support the driving motor 442 and the jig 41, thereby ensuring that the jig 41 can stably rotate under the driving action of the driving motor 442.

[0035] In some optional embodiments, as shown in Figure 4As shown, the jig 41 comprises a rotating shaft part 411 and a supporting part 412, the rotating shaft part 411 is fitted in the fitting hole, one end of the rotating shaft part 411 extends out of the fitting hole 51 and is connected with the shaft coupling 443, the supporting part 412 is connected with the other end of the rotating shaft part 411, the horizontal part 4411 is provided with a bearing seat 444, the bearing seat 444 is sleeved on the rotating shaft part 411, and a rolling bearing is arranged between the bearing seat 444 and the rotating shaft part 411. Thus, during the rotation of the jig 41, the rolling bearing can reduce the friction between the jig 41, the bearing seat 444 and the second driving seat 441, so as to ensure that the jig 41 can rotate stably.

[0036] In some optional embodiments, the rotating shaft part 411 is further provided with a photoelectric detection sheet 6, the photoelectric detection sheet 6 is provided with a notch 61, the second driving seat 441 is provided with a photoelectric detector, and the emitting end and the receiving end of the photoelectric detector are located on the two sides of the photoelectric detection sheet 6 respectively. It can be understood that the interaction between the photoelectric detector and the photoelectric detection sheet 6 can make the battery 7 stop stably after rotating through a specified angle, so as to facilitate the second measurement of the image detection module 2.

[0037] In some embodiments, the support 1 comprises a supporting plate 11 and a plurality of columns 12, the plurality of columns 12 are arranged on the supporting plate 11 in a length direction of the supporting plate 11, and the test platform 5 and the image detection module 2 are detachably arranged on the supporting plate 11. Thus, the supporting plate 11 can ensure the stability of the image detection module 2, the reference part 3 and the driving mechanism 4, and the columns 12 can ensure that the battery seal size detection device has sufficient height and is convenient for placing the battery 7.

[0038] In some embodiments, the side, away from the supporting plate 11, of the column 12 is provided with a supporting cushion plate 121, and the supporting cushion plate 121 is used for fixedly connecting with an external workbench. Thus, the battery seal size detection device can be stably placed on the external workbench, so as to facilitate the use of the battery seal size detection device.
