It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described here.

[0039] like Figure 1As shown, the present application provides a cylindrical lithium battery cell shelling device, including a battery shell clamping mechanism 100, a battery shell feeding mechanism 400, a calibration mechanism 200, a battery cell feeding mechanism 500 and a push rod mechanism 300. The battery shell clamping mechanism 100 and the battery cell feeding mechanism 500 are respectively located at both ends of the calibration mechanism 200. The battery cell 700 clamped on the battery cell feeding mechanism 500 is calibrated by the calibration mechanism 200 and then sent into the battery shell 600 clamped by the battery shell clamping mechanism 100 to complete the loading of the battery cell 700. The push rod mechanism 300 is used to drive the battery cell 700 to move toward the battery shell 600. The battery shell clamping mechanism 100 has a first clamp 130 for clamping the first end 601 of the battery shell 600; a calibration mechanism 200, the calibration mechanism 200 has a second clamp 214 for clamping the second end 602 of the battery shell 600 and a third clamp 220 coaxially arranged with the second clamp 214; the push rod mechanism 300 has a push rod 310 that reciprocates axially along the third clamp 220, and the push rod 310 is used to push the battery cell 700 to move axially along the calibration mechanism 200 so that the battery cell 700 enters the battery shell 600. During operation, the first clamp 130 clamps the first end 601 of the battery shell 600, and the second clamp 214 clamps the second end 602 of the battery shell 600. Since the third clamp 220 is coaxially arranged with the second clamp 214, the battery shell 600 clamped by the first clamp 130 and the second clamp 214 can be coaxially aligned with the third clamp 220. When the push rod mechanism 300 pushes the battery cell 700 through the third clamp 220, it can directly enter the battery shell 600, thereby realizing the automatic loading of the battery cell 700 into the battery cell shell. At the same time, the assembly accuracy is improved, and the occurrence of problems such as jamming, distortion, deformation and scrapping of the battery cell during the process of loading into the battery shell 600 is greatly reduced.

[0040] like Figure 2-3As shown, the battery shell clamping mechanism 100 is used to clamp and fix the battery shell 600, which includes a mobile driving member 110 placed along a first direction and a mounting substrate 120 fixed on the mobile driving member 110. The mobile driving member 110 can be a hydraulic press or a cylinder, which is used to drive the mounting substrate 120 to move along the second direction. A plurality of first clamps 130 are evenly spaced on the end surface of the mounting substrate 120 facing the calibration mechanism 200, and the first clamp 130 is used to clamp the end of the battery shell 600 to be loaded with the battery cell 700. The first clamp 130 includes an outer ring 131 and a plurality of first clamps 132 (the number of first clamps 132 is not less than two). The first clamp 132 is an arc-shaped plate, and a plurality of first clamps 132 are evenly spaced and fit in the inner ring of the outer ring 131. On the outer ring 131, a first electric push rod 133 is provided at a position corresponding to each first clamping plate 132. The main body of the first electric push rod 133 is fixed on the outer ring of the outer ring 131, and its telescopic shaft passes through the wall of the outer ring 131 and is fixedly connected to the first clamping plate 132 corresponding to each other. When the telescopic shaft of the first electric push rod 133 is extended, it pushes the corresponding first clamping plate 132 to move closer to the center of the outer ring 131, and thereby clamps and fixes the end of the battery housing 600 located in the outer ring 131. By pushing the first clamping plate 132 to clamp the battery housing 600 by the first electric push rod 133, it can adapt to the assembly work of battery housings 600 of different diameters, and the clamping position of the battery housing 600 can also be adjusted by the first electric push rod 133, so that the battery housing 600 and the battery cell 700 remain coaxial during the assembly process, so that the battery cell 700 can be accurately inserted into the battery housing 600, thereby improving the assembly accuracy.

[0041] like Figure 6As shown, the battery case feeding mechanism 400 can carry the battery case 600 in and out of the designated position between the battery case clamping mechanism 100 and the calibration mechanism 200. The battery case feeding mechanism 400 includes a first row of clamps 410 and a second row of clamps 420. The first row of clamps 410 and the second row of clamps 420 are fixed in parallel on the base. The first row of clamps 410 and the second row of clamps 420 are both composed of a plurality of V-shaped grooves 430 arranged in a straight line at equal intervals. And the V-shaped grooves 430 on the first row of clamps 410 and the V-shaped grooves 430 on the second row of clamps 420 correspond one to one, so that the V-shaped grooves 430 on the first row of clamps 410 and the V-shaped grooves 430 on the corresponding second row of clamps 420 can form a V-shaped support point to support the two ends of the battery case 600. The battery case feeding mechanism 400 is designed with a V-shaped groove 430, which can be used to transport battery cases 600 of different diameters, so as to achieve a multi-purpose tool. The battery case feeding mechanism 400 can move in a track 320 manner. When loading the battery cell 700, the battery case feeding mechanism 400 carrying the battery case 600 enters between the battery case clamping mechanism 100 and the calibration mechanism 200. After loading the battery cell, the battery case 600 carrying the loaded battery cell exits between the battery case clamping mechanism 100 and the calibration mechanism 200.

[0042] like Figure 4-5As shown, the calibration mechanism 200 includes a plurality of calibration units 210 arranged side by side, and the number and position of the calibration units 210 correspond to the first fixtures 130 on the mounting substrate 120. The calibration unit 210 includes a mounting platform 211 and a movable base 212. The movable base 212 is composed of a base and an arc-shaped slideway arranged on the base. The arc-shaped slideway extends along the length direction of the base. The mounting platform 211 has a slider 213, which is a rectangular plate placed on the movable base 212 and slides along the length direction of the movable base 212. The third fixture 220 is fixed in the middle area of ​​the slider 213. The third fixture 220 is a cylindrical structure, and its bottom passes through the slider 213 and fits in the arc-shaped slideway of the movable base 212. An opening 217 is provided at the top of the third fixture 220, and the opening 217 extends along the length direction of the third fixture 220. The bottom of the third fixture 220 is fitted with the arc-shaped slideway of the mobile base 212 to increase the contact area between the two and avoid deformation of the third fixture 220. In addition, it can also play a limiting role to prevent the third fixture 220 from sliding laterally out of the arc-shaped slideway. The third fixture 220 is provided with a plurality of second clamps 215, and the second clamps 215 are arc-shaped plates, which are evenly spaced and fitted on the inner wall of the third fixture 220. The outer wall of the third fixture 220 is provided with a second electric push rod 216, and the telescopic shaft of the second electric push rod 216 passes through the wall of the third fixture 220 and is fixedly connected to the second clamp 215. Each second clamp 215 is connected to a corresponding second clamp 215. The second electric push rod 216 can push its corresponding second clamp 215 to the center of the third fixture 220 by extending the telescopic shaft, so as to make the battery cell 700 coaxial with the third fixture 220. The third clamp 220 is fixedly connected to a second clamp 214 at one end close to the battery shell clamping mechanism 100. The second clamp 214 has the same structure as the first clamp 130. The second clamp 214 and the third clamp 220 are coaxially arranged, so that the battery shell 600 and the battery cell 700 remain coaxial during the assembly process, so that the battery cell 700 can be accurately inserted into the battery shell 600, thereby improving the assembly accuracy.

[0043] like Figure 6As shown, the structure of the battery cell feeding mechanism 500 is the same as that of the battery shell feeding mechanism 400. It includes a first row of clamps 410 and a second row of clamps 420. The first row of clamps 410 and the second row of clamps 420 are fixed in parallel on the base. The first row of clamps 410 and the second row of clamps 420 are both composed of a plurality of V-grooves 430 arranged in a straight line at equal intervals. And the V-grooves 430 on the first row of clamps 410 and the V-grooves 430 on the second row of clamps 420 correspond one to one, so that the V-grooves 430 on the first row of clamps 410 and the V-grooves 430 on the corresponding second row of clamps 420 can form a V-shaped support point to support the two ends of the battery cell 700. The battery cell feeding mechanism 500 structure is used to carry the battery cells 700 to be loaded into the other end of the calibration mechanism 200. When working, the battery cell feeding mechanism 500 loads the battery cells at the loading position, and after loading is completed, it carries the battery cells to the other side of the calibration mechanism 200, and controls the battery cells on the battery cell feeding mechanism 500 to align with the calibration units 210 of each calibration mechanism 200, and waits for the battery cell feeding mechanism 500 to withdraw after loading is completed. The in and out movement of the battery cell feeding mechanism 500 is driven by a hydraulic press or a pneumatic press.

[0044] like Figure 1 As shown, the push rod mechanism 300 includes a track 320 arranged along the second direction, and both ends of the track 320 are fixed by vertical rods. The track 320 spans the entire battery shell clamping mechanism 100, the battery shell feeding mechanism 400, the calibration mechanism 200 and the battery cell feeder. The track 320 is slidably connected to the slide 340, and the slide 340 is driven by a hydraulic press to slide on the guide rail. A crossbeam 330 is fixed to the lower end of the slide 340, and the crossbeam 330 is arranged along the first direction. A plurality of push rods 310 are arranged at equal intervals on the crossbeam 330. The push rod 310 is coaxial with the battery cell 700 on the battery cell feeding mechanism 500, and is used to push the battery cell 700 into the calibration unit 210 of the calibration mechanism 200.

[0045] In the present application, the following steps are required to load the battery cell 700 and the battery housing 600 using the cylindrical lithium battery cell shell loading device:

[0046] S1: In the loading area of ​​the battery shell feeding mechanism 400, the battery shell 600 is loaded into the V-shaped groove 430 of the battery shell feeding mechanism 400. The loading of the battery shell 600 can be done manually or by a robot arm. Then the battery shell feeding mechanism 400 carrying the battery shell 600 is fed between the battery shell clamping mechanism 100 and the calibration mechanism 200 by a hydraulic press, and the battery shell 600 on the battery shell feeding mechanism 400 corresponds to the first clamp 130 of the battery shell clamping mechanism 100 one by one.

[0047] S2: In the battery cell 700 loading area, the battery cell 700 is loaded into the V-shaped groove 430 of the battery cell feeding mechanism 500. The loading of the battery cell 700 can also be completed manually or by a robot. Then the battery cell feeding mechanism 500 carrying the battery cell 700 is fed between the push rod mechanism 300 and the calibration mechanism 200 by a hydraulic press, and the battery housing 600 on the battery cell feeding mechanism 500 is made to correspond one to one with the third fixture 220 of the calibration unit 210.

[0048] S3: Start the push rod mechanism 300, so that the slide 340 moves along the track 320 toward the calibration mechanism 200. The push rod 310 on the slide 340 pushes the end of the battery cell 700 on the battery cell feeding mechanism 500, so that one end of the battery cell 700 enters the third fixture 220 of the calibration unit 210. After all the battery cells 700 enter the third fixture 220, start the second electric push rod 216 on the third fixture 220, and the plurality of second clamps 215 in the third fixture 220 move toward the center and push the battery cells 700 in the third fixture 220 to finally remain coaxial with the third fixture 220, so as to achieve calibration of the battery cells 700.

[0049] S4: At the same time as S3 is started, the mobile driving member 110 of the battery shell clamping mechanism 100 moves toward the battery shell feeding mechanism 400 under the drive of the hydraulic press, and drives the first clamp 130 on the mounting substrate 120 to move toward the battery shell 600, so that one end of the battery cell shell enters the inner circle of the first clamp 130. The first electric push rod 133 on the first clamp 130 is started, pushing the first clamping plate 132 to move toward the axis of the first clamp 130, clamping and fixing the corresponding battery shell 600. After the first clamp 130 clamps the shell, the mobile driving member 110 continues to push the mounting substrate 120 to move in the second direction, so that the other end of the battery shell 600 enters the first clamp 130 on the calibration mechanism 200, and the first clamp 130 on the calibration mechanism 200 clamps the other end of the battery shell 600. By installing the first clamp 130 on the substrate 120 and the first clamp 130 on the calibration mechanism 200 to clamp the two ends of the battery shell 600 respectively, the axis line of the battery shell 600 can be aligned with the axis line of the third clamp 220 of the calibration mechanism 200. The battery cell can smoothly enter the battery shell 600 under the guidance of the third clamp 220 without deflection.

[0050] S5: The push rod mechanism 300 continues to push the battery cell 700 to move in the third clamp 220, and the battery cell 700 moves axially along the third clamp 220, passes through the first clamp 130 at the end of the third clamp 220 and enters the battery housing 600, completing the loading action of the battery cell housing and the battery housing 600.

[0051] The present application can realize precise loading of battery cases 600 and battery cells 700 through the battery case clamping mechanism 100, the battery case feeding mechanism 400, the calibration mechanism 200, the battery cell feeding mechanism 500 and the push rod mechanism 300. The whole process is automated, which not only saves manpower but also improves loading efficiency and greatly improves production efficiency.

[0052] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
