[0025] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings.

[0026] like Figure 1 and Figure 2As shown, a battery size detection mechanism 10 includes: a conveying device 100, a size detection device 200 and a lifting device 300. The conveying device 100 includes a feeding belt 110 and a loading jig 120. The loading jig 120 is arranged on the feeding belt 110. The feeding belt 110 is provided with a detection area. The lifting device 300 and the size detection device 200 are respectively located on both sides of the detection area. When the feeding belt 110 drives the battery 20 on the loading jig 120 to move to the detection area, the lifting device 300 is used to lift the battery 20 from the loading jig 120, and the size detection device 200 is used to detect the diameter and thickness of the lifted battery 20.

[0027] It should be noted that the feeder belt 110 is a chain feeder belt, which has the advantages of accurate and stable conveying speed, and can ensure accurate synchronous conveying. There are multiple loading jigs 120, and each loading jig 120 is arranged at intervals on the feeder belt 110. The feeder belt 110 continuously moves the loading jig 120 containing the battery to be tested to the detection area, and stops between the lifting device 300 and the size detection device 200, wherein the lifting end of the lifting device 300 is located below the loading jig 120 and is aligned with the bottom of the battery 20 on the loading jig 120, and then the battery 20 is lifted up from the loading jig by the lifting device 300, so that the size detection device 200 can perform size detection on the battery 20. In this embodiment, a plurality of battery placement cavities are provided on the carrier jig 120. For example, four battery placement cavities are provided on the carrier jig 120, and correspondingly, two inspection areas are also provided on the feeder belt 110. The feeder belt 110 first transfers the battery 20 to the first inspection area, and performs size inspection on the first battery 20 and the third battery 20 on the carrier jig 120. After the inspection of the first battery 20 and the third battery 20 is completed, the feeder belt 110 continues to transfer the carrier jig 120 to the second inspection area, and performs size inspection on the second battery 20 and the fourth battery 20 on the carrier jig 120. In this way, the feeder belt 110 continuously transfers the carrier jig 120 to the first inspection area and the second inspection area for size inspection of the battery 20, thereby realizing full automation of the diameter and thickness inspection of the battery 20 and improving the efficiency of the inspection.

[0028] Combine Figure 5 and Figure 6 As shown, in one embodiment, the size detection device 200 includes a thickness detection module 210 and a diameter detection module 220 , the thickness detection module 210 and the diameter detection module 220 are respectively located on one side of the detection area, and the thickness detection module 210 is arranged on the diameter detection module 220 .

[0029] It should be noted that the thickness detection module 210 is used to measure the thickness of the battery 20, and the diameter detection module 220 is used to measure the diameter of the battery 20. The thickness detection module 210 and the diameter detection module 220 are respectively located on the same side of the detection area and are arranged opposite to the jacking device 300 on the other side of the detection area. In addition, the thickness detection module 210 is arranged on the diameter detection module 220. In this way, the size detection mechanism can be made more compact and more production space can be saved. Moreover, when the feeding belt 110 moves the battery 20 to be detected to the detection area, the jacking end of the jacking device 300 is located on the battery 20 to be detected on the carrier fixture 120. At the same time, the thickness measuring end of the thickness detection module 210 is located at the top of the battery 20 to be detected on the loading jig 120, and the detection end of the diameter detection module 220 is arranged opposite to the side of the battery to be detected. When the lifting device 300 ejects the battery 20 from the loading jig 120, the thickness measuring end of the thickness detection module 210 also forms a certain return stroke upward, thereby obtaining the thickness data of the battery 20. At the same time, the diameter detection module 220 photographs and detects the side of the battery 20, thereby obtaining the diameter data of the battery 20. In this way, the diameter and thickness detection of the battery 20 can be completed at one time at the same workstation, which greatly improves the detection efficiency.

[0030] Furthermore, the diameter detection module 220 includes a support member 221, an adjustment member 222 and a CCD camera 223. The support member 221 is arranged on one side of the feed belt 110, the adjustment member 222 is slidably arranged on the support member 221, the CCD camera 223 is arranged on the adjustment member 222, and the detection end of the CCD camera 223 is located on the detection area. The adjustment member 222 is used to adjust the distance from the detection end of the CCD camera 223 to the loading fixture 120.

[0031] It should be noted that the support member 221 is fixedly arranged on one side of the feed belt 110. Through the support member 221, the height of the detection end of the CCD camera 223 is aligned with the height of the battery 20 ejected from the carrier jig 120 by the lifting device 300, and the horizontal distance from the detection end of the CCD camera 223 to the carrier jig 120 is adjusted by the adjustment member 222. In this way, the detection end of the CCD camera 223 can be placed at the optimal shooting angle, thereby improving the detection accuracy of the battery 20.

[0032] In one embodiment, the support member 221 includes a base 221a and a guide plate 221b. The base 221a is disposed on one side of the feeding belt 110, the guide plate 221b is disposed on the base 221a, and the adjustment member 222 is slidably disposed on the guide plate 221b.

[0033] It should be noted that the guide plate 221b is installed on the fixed base 221a, and a guide rail is provided on the guide plate 221b. The adjusting member 222 is slidably connected to the guide rail. By adjusting the adjusting member 222, the adjusting member 222 is moved along the guide rail to move the CCD camera 223 close to the material loading fixture 120, so that the CCD camera 223 is in the best shooting position.

[0034] Furthermore, in order to achieve the stability of the position movement and the convenience of position adjustment of the CCD camera 223, the adjustment member 222 includes a sliding table 222a, a screw rod 222b and an adjustment handwheel 222c. The sliding table 222a is slidably connected to the guide plate 221b, and the CCD camera 223 is arranged on the sliding table. One end of the screw rod 222b is connected to the sliding table 222a, and the other end of the screw rod 222b is connected to the adjustment handwheel 222c.

[0035] It should be noted that the sliding platform 222a is provided with a sliding portion that is connected to the guide rail on the guide plate 221b. By rotating the adjustment handwheel 222c, the sliding portion on the sliding platform 222a can be moved along the guide rail of the guide plate 221b, thereby facilitating adjustment of the position of the CCD camera 223. In this embodiment, the adjustment member 222 also includes a locking block and a locking handle. The locking block is provided on the guide plate 221b and extends through the screw rod 222b. The locking handle is connected to the locking block. In this way, after the CCD camera 223 is adjusted to the appropriate position, the adjustment handwheel 222c can be locked by the locking block, thereby ensuring that the CCD camera 223 will not move due to accidental contact with the adjustment handwheel 222c.

[0036] In one embodiment, the thickness detection module 210 includes a thickness measuring support frame 211 and a thickness measuring piece 212. The thickness measuring support frame 211 is set on the base 221a, and the thickness measuring piece 212 is set on the side of the thickness measuring support frame 211 close to the detection area. The thickness measuring end of the thickness measuring piece 212 is aligned with the battery 20 on the loading fixture 120.

[0037] It should be noted that the thickness detection module 210 is used to measure the thickness of the battery 20, and the thickness measuring piece 212 is arranged on the side of the thickness measuring support frame 211 close to the detection area. In this way, when the loading jig 120 stops at the detection area, the thickness measuring end of the thickness measuring piece 212 is located above the loading jig 120 and is aligned with the battery 20 on the loading jig 120. The lifting device 300 ejects the battery 20 on the loading jig 120, and the ejection stroke of the lifting device 300 is a fixed value. When the upper surface of the battery 20 on the loading jig 120 contacts the thickness measuring end of the thickness measuring piece 212, the thickness measuring end forms a certain return stroke upward, so that the thickness data of the battery 20 can be obtained.

[0038] Furthermore, the thickness measuring part 212 includes a thickness measuring sensor 212a, a thickness measuring column 212b and a column head 212c. The thickness measuring sensor 212a is arranged on the support frame 211, one end of the thickness measuring column 212b is connected to the thickness measuring sensor 212a, and the other end of the thickness measuring column 212b is connected to the column head 212c, and the column head 212c is aligned with the battery 20 on the loading fixture 120.

[0039] It should be noted that when the loading jig 120 transfers the battery 20 to be tested to the testing area, the thickness measuring column 212b and the column head 212c are located directly above the battery 20 to be tested, and the lifting device 300 is located directly below the battery to be tested. When the lifting device 300 lifts the battery 20 to be tested upward from the loading jig 120 for a distance, the column head 212c contacts the upper surface of the battery 20 to be tested. At this time, the plane where the lifting device 300 contacts the battery 20 to be tested is used as the zero point, and the ejection stroke of the lifting device 300 is a fixed value. The lifting device 300 continues to lift the battery 20 to be tested upward for a certain distance, and the thickness measuring column 212b and the column head 212c retract upward to form a certain return stroke. The thickness measuring sensor 212a obtains the thickness data of the battery 20 and completes the thickness measurement of the battery 20.

[0040] Combine Figure 5 As shown, in order to further improve the accuracy of the contact sensing of the column head 212c, the contact sensing end of the column head 212c is a semicircular structure.

[0041] It should be noted that the contact sensing end of the column head 212c is a semicircular structure. In this way, the contact between the battery 20 to be tested and the column head 212c can be point contact. Once the battery 20 to be tested contacts the semicircular center point of the column head 212c, the thickness sensor 212a responds quickly, thereby improving the accuracy of the contact sensing of the column head 212c.

[0042] Furthermore, in order to prevent the battery 20 to be tested from being subjected to excessive contact force with the column head 212c when being ejected, which would cause the thickness measuring column 212b to cause secondary damage to the upper surface of the battery 20 due to inertia, the thickness measuring column 212b is configured as an elastic structure.

[0043] It should be noted that the connection between the traditional thickness measuring column and the thickness measuring sensor is not fixed. When the battery 20 is lifted up, the entire thickness measuring column is also lifted up, thereby obtaining the thickness of the battery 20. However, this structure is prone to cause the thickness measuring column to rebound due to inertia when the ejection force is large, causing secondary damage to the surface of the battery 20. Therefore, in this embodiment, the thickness measuring column 212b is configured as an elastic structure, and the connection end of the thickness measuring column 212b and the thickness measuring sensor 212a is not fixed. Therefore, when the thickness measuring column 212b retracts upward, the entire thickness measuring column 212b is not lifted up, but retracts upward through the elastic structure, thereby avoiding the ejection force of the lifting device 300 when lifting the battery 20 being too large, resulting in the thickness measuring column 212b causing secondary damage to the upper surface of the battery 20 due to inertia.

[0044] Combine Figure 3 and Figure 4 As shown, in one embodiment, the jacking device 300 includes a jacking support 310, a jacking column 320 and a jacking drive 330. The jacking support 310 is on one side of the feeding belt 110, and the jacking drive 330 is arranged on the jacking support 310. The jacking column 320 is connected to the jacking drive 330. When the feeding belt 110 drives the battery 20 on the loading jig 120 to move to the detection area, the jacking column 320 is located below the battery 20. The jacking drive 330 is used to drive the jacking column 320 to perform a jacking movement in the direction of the loading jig 120 so that the jacking column 320 can eject the battery 20 from the loading jig 120.

[0045] It should be noted that there are two top columns 320, which correspond to the two batteries 20 to be tested on the loading jig 120. When the feeding belt 110 drives the battery 20 on the loading jig 120 to move to the testing area, the top column 320 is located below the battery 20 and is driven by the lifting drive 330 to lift the battery 20 on the loading jig 120 upward. After completing the size detection of the battery 20, the lifting drive 330 is reset and drives the top column 320 back to the initial position again.

[0046] Furthermore, the lifting support member 310 includes a bracket 311 and a lifting guide member 312, the bracket 311 is arranged on one side of the feeding belt 110, the lifting guide member 312 is arranged on the bracket 311, the lifting column 320 is arranged on one end of the lifting guide member 312 close to the loading fixture 120, and the lifting drive member 330 is slidably connected to the lifting guide member 312.

[0047] It should be noted that the lifting guide member 312 also includes a transverse guide plate 312a and a longitudinal guide plate 312b. The transverse guide plate 312a is arranged on the bracket 311, and one end of the longitudinal guide plate 312b is connected to the end of the transverse guide plate 312a close to the detection area. The transverse guide plate 312a and the longitudinal guide plate 312b are respectively slidably connected to the lifting drive member 330. Similarly, the lifting drive member 330 is provided with a longitudinal sliding portion and a transverse sliding portion, and the lifting column 320 is provided on the transverse sliding portion. After the lifting drive member 330 is started, the transverse sliding portion moves transversely along the transverse guide plate 312a, and at the same time drives the longitudinal sliding portion to move upward along the longitudinal guide plate 312b, thereby driving the lifting column 320 to move upward and eject the battery 20 from the loading fixture 120.

[0048] Combine Figure 3 and Figure 4 As shown, in one embodiment, the traditional ejection mechanism only uses a cylinder to connect the ejector column, and the ejector column is lifted up by the drive of the cylinder. However, this method is more difficult to control the stability and driveability of the cylinder drive. Therefore, in order to improve the stability and accuracy of the upward movement of the ejector column 320 and avoid excessive ejection force when the ejector column 320 pushes the battery 20 upward, causing damage to the battery 20. The lifting drive component 330 includes a cylinder 331, a transverse slider 332, a guide block 335, a longitudinal slider 333 and a follower 334. The cylinder 331 is connected to the transverse slider 332. The transverse slider 332 is slidably set on the transverse guide plate 312a, and the guide block 335 is set on the side of the transverse slider 332 away from the transverse guide plate 312a. One end of the follower 334 is connected to the longitudinal slider 333, and the other end of the follower 334 is slidably connected to the guide block 335. The longitudinal slider 333 is slidably set on the longitudinal guide plate 312b. The jacking column 320 is set on the side of the longitudinal slider 333 close to the loading fixture 120.

[0049] It should be noted that the guide block 335 is a wedge-shaped guide block 335, and a sliding arc surface is provided on the wedge-shaped guide block 335. The follower 334 is a cam bearing follower 334, and a cam is provided on the cam bearing follower 334, and the cam is in contact with the sliding arc surface on the wedge-shaped guide block 335. When the jacking operation is performed, the cylinder 331 is extended to push the horizontal slider 332 to move along the horizontal guide plate 312a toward the direction of the feed belt 110. In this way, the wedge guide block 332 on the horizontal slider 332 is 35 also moves in the direction of the conveyor belt 110. At the same time, the cam on the cam bearing follower 334 rotates upward along the sliding arc surface on the wedge-shaped guide block 335, thereby driving the longitudinal slider 333 to move upward along the longitudinal guide plate 312b, so that the ejector column 320 ejects the battery 20 from the loading fixture upward. In this way, not only the stability and accuracy of the upward movement of the ejector column 320 can be guaranteed, but also the ejection force of the ejector column 320 can be avoided to be too large, which may cause damage to the battery 20 to be tested.

[0050] Furthermore, in order to ensure smooth reset after the jacking operation is completed, the jacking device 330 also includes a fixed block 370 and a reset elastic member 380. The fixed block is arranged on the jacking guide member 312, and one end of the reset elastic member 380 is connected to the longitudinal slider 333, and the other end of the reset elastic member 380 is connected to the fixed block 370.

[0051] It should be noted that the reset elastic member 380 is a reset spring. After the jacking operation of the jacking column 320 is completed, the reset spring gradually returns to its initial state from the stretched state. During the restoration process, the cylinder 331 slowly retracts, and the longitudinal slider 333 gradually moves downward along the longitudinal guide plate 312b driven by the reset spring. At the same time, the cam bearing follower 334 gradually rotates downward along the sliding arc surface and pushes the wedge-shaped guide block 335 to move, finally allowing each component to smoothly return to its initial position.

[0052] Combine Figure 3 and Figure 4 As shown, in one embodiment, in order to improve the detection accuracy of the CCD camera 223 during the diameter detection process of the battery 20, the lifting device 300 also includes a fixing plate 340, a heat dissipation plate 350 and a light source 360, the fixing plate 340 is arranged on the lifting guide 312 shown, the heat dissipation plate 350 is arranged on the fixing plate 340, the light source 360 ​​is arranged on the heat dissipation plate 350, and the light source 360 ​​is aligned with the detection end of the CCD camera 223.

[0053] It should be noted that the light source 360 ​​is aligned with the detection end of the CCD camera 223. Thus, when the CCD camera 223 photographs and detects the battery 20 to be inspected, the light source 360 ​​can provide sufficient light to ensure clarity of the image captured by the CCD camera 223, thereby improving the accuracy of the dimensional detection of the battery 20. In this embodiment, multiple light sources 360 are provided. Preferably, two light sources 360 are provided, with the two light sources 360 corresponding to the two CCD cameras 223. The heat sink 350 is provided with a light source mounting portion and a mounting fixing portion. The mounting fixing portion is provided with a strip-shaped adjustment hole. Similarly, the fixing plate 340 is provided with a mounting hole corresponding to the strip-shaped adjustment hole. The strip-shaped adjustment hole allows the distance between the light source 360 ​​and the CCD camera 223 to be appropriately adjusted. The light source 360 ​​is mounted and fixed to the light source mounting portion. Thus, the heat generated by the light source 360 ​​can be dissipated by the heat sink 350, thereby increasing the service life of the light source 360.

[0054] In one embodiment, a battery placement cavity is defined on the loading fixture 120 , and a top column avoidance hole is defined at the bottom of the battery placement cavity. The top column avoidance hole is aligned with the top column 320 .

[0055] It should be noted that the top post avoidance hole is aligned with the top post 320 and is larger than the top post 320. This allows the top post 320 to quickly pass through the top post avoidance hole while avoiding collision with the loading fixture 120. In this embodiment, the battery placement cavity is provided with a guide inclined surface, so that the battery 20 can be quickly inserted into the battery placement cavity.

[0056] Furthermore, an optical fiber avoidance groove is provided on the loading fixture 120, and the optical fiber avoidance groove is communicated with the battery placement cavity.

[0057] It should be noted that a fiber optic sensor is provided on one side of the feed belt 110, and the fiber optic emitting end of the fiber optic sensor is aligned with the fiber optic avoidance groove. The fiber optic sensor is used to check whether a battery is placed on the battery placement cavity. In this way, it can avoid the occurrence of empty inspections in the subsequent size detection process, thereby improving the detection efficiency of the battery 20.

[0058] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
