[0030] Figure 2 It is the second perspective view of the mechanism for positioning the battery cell in the embodiment of the present invention.

[0031] Figure 3 It is the structural schematic diagram of the mechanism for positioning the battery cell in the embodiment of the present invention.

[0032] As Figures 1-3 shown, the mechanism for positioning the battery cell (hereinafter referred to as the positioning mechanism) 100 in this embodiment includes a feeding mechanism 1, a bottom support mechanism 2, and a plurality of positioning units 3.

[0033] Figure 4 It is the structural schematic diagram of the feeding mechanism in the embodiment of the present invention.

[0034] As Figures 1-4 shown, the feeding mechanism 1 is used to place the battery cell, and the feeding mechanism 1 includes a feeding plate 101 and a plurality of push blocks 102.

[0035] The feeding plate 101 is arranged in a rectangle and is used to place the battery cell. A plurality of weight reduction holes are provided on the feeding plate 101.

[0036] The plurality of push blocks 102 are conical and are fixedly connected to the feeding plate 101, and are used to cooperate with the plurality of positioning units 3 to position the battery cell.

[0037] In this embodiment, six push blocks 102 are provided. Two of them are located at two diagonal corners of the feeding plate 101, and the remaining four are arranged in the middle of the feeding plate 101 and are symmetrically distributed along the length and width directions of the feeding plate 101.

[0038] Figure 5 It is the structural schematic diagram of the bottom support mechanism in the embodiment of the present invention.

[0039] As Figures 1-3 and Figure 5 shown, the bottom support mechanism 2 is used to support the material discharging mechanism 1. The bottom support mechanism 2 includes a fixed bottom plate 201 and a plurality of support units.

[0040] The support unit includes a linear bearing seat 202, a limit sleeve 203 and a support guide rod 204.

[0041] The linear bearing seat 202 is arranged on the fixed bottom plate 201. The support guide rod 204 is slidably connected with the linear bearing seat 202. One end of the support guide rod 204 far away from the linear bearing seat 202 is fixedly connected with the material discharging plate 101 for supporting the material discharging plate 101. The limit sleeve 203 is arranged on the linear bearing seat 202 for limiting the extreme descending position of the material discharging plate 101.

[0042] Specifically, when the battery cell is placed on the material discharging plate 101, the gravity pressure of the battery cell drives the material discharging plate 101 and the support guide rod 204 to displace downward along the linear bearing seat 202, and the material discharging plate 101 can descend to the position of the limit sleeve 203 at most.

[0043] Figure 6 is a schematic structural diagram of the long side positioning unit in the embodiment of the present invention.

[0044] Figure 7 is a first schematic structural diagram of the short side positioning unit in the embodiment of the present invention.

[0045] Figure 8 is a second schematic structural diagram of the short side positioning unit in the embodiment of the present invention.

[0046] As Figures 1-3 and Figures 6-8 shown, a plurality of positioning units 3 are arranged around the fixed bottom plate 201 and are used to cooperate with the push block 102. When the battery cell is placed on the material discharging plate 101 to generate gravity pressure, the material discharging plate 101 and the push block 102 are pressed down, driving the positioning unit 3 to displace and contact the battery cell to center the battery cell.

[0047] The positioning unit 3 includes at least one adjustment component 301, a positioning block mounting plate 302 and a plurality of adjustment positioning blocks 303.

[0048] The positioning block mounting plate 302 is connected to the adjustment assembly 301. The positioning unit 3 is divided into a long-side positioning unit and a short-side positioning unit. The positions of the long-side positioning unit correspond to the positions of the two long sides of the blanking plate 101. The positions of the short-side positioning unit correspond to the positions of the two short sides of the blanking plate 101. Two adjustment assemblies 301 are connected to the positioning block mounting plate 302 of the long-side positioning unit. The two adjustment assemblies 301 are symmetric with respect to the central axis of the long side of the blanking plate 101. The adjustment assembly 301 and the positioning block mounting plate 302 are distributed at a right angle. The positions of the two adjustment assemblies 301 respectively correspond to the positions of the two push blocks 102 located in the middle of the blanking plate 101 and close to one side of the long-side positioning unit.

[0049] One adjustment assembly 301 is connected to the positioning block mounting plate 302 of the short-side positioning unit. The adjustment assembly 301 is located in the middle of the positioning block mounting plate 302 and is distributed at a right angle to the positioning block mounting plate 302. The position of the adjustment assembly 301 corresponds to the position of the push block 102 located at the diagonal of the blanking plate 101 and close to the short-side positioning unit. The adjustment positioning block 303 is fixedly connected or detachably connected to the positioning block mounting plate 302 and is used to displace towards the direction close to the blanking plate 101 under the drive of the adjustment assembly 301 and then contact and push the battery cell to center the battery cell.

[0050] The adjustment positioning block 303 is arranged in an L shape and includes a horizontal section and a vertical section connected perpendicularly. The horizontal section is connected to the positioning block mounting plate 302, and the vertical section is used to push the battery cell.

[0051] Specifically, the position of the adjustment positioning block 303 on the positioning block mounting plate 302 is determined according to the size of the battery cell. When the battery cells are of a unified size, the adjustment positioning block 303 can be directly fixedly connected to the positioning block mounting plate 302. When the battery cell sizes are not unified, the adjustment positioning block 303 is detachably connected to the positioning block mounting plate 302, which is convenient for adjusting the position of the adjustment positioning block 303 according to the size of the battery cell and then fixing it with bolts.

[0052] Specifically, when the battery cell is placed on the blanking plate 101, the gap between the side of each adjustment positioning block 303 close to the battery cell and the battery cell is about 5 mm.

[0053] The adjustment assembly 301 includes an adjustment assembly bearing seat 3011, a guide rod 3012, a connecting rod 3014, a connecting rod rotating shaft 3015, a spring 3016, and a spring retaining sleeve 3017.

[0054] The adjustment assembly bearing seat 3011 is connected to the fixed bottom plate 201.

[0055] The guide rod 3012 is inserted into the adjustment component bearing seat 3011 and is slidably connected to the adjustment component bearing seat 3011. One end is connected to the positioning block mounting plate 302. A circlip 3013 is provided on the side of the adjustment component bearing seat 3011 away from the positioning block mounting plate 302 for maintaining the initial position of the guide rod 3012.

[0056] A spring 3016 is sleeved on the guide rod 3012. The spring 3016 is located between the adjustment component bearing seat 3011 and the positioning block mounting plate 302. Spring collars 3017 are provided at both ends of the spring 3016. One spring collar 3017 abuts against the adjustment component bearing seat 3011, and the other spring collar 3017 abuts against the positioning block mounting plate 302.

[0057] The connecting rod 3014 is rotatably connected to the other end of the guide rod 3012 through a pin shaft 3019. A travel hole is provided at one end of the connecting rod 3014 close to the guide rod 3012, and a through hole is provided at one end of the guide rod 3012 close to the connecting rod 3014. The pin shaft 3019 passes through the travel hole and the through hole. A fixing circlip 3020 is provided on the pin shaft 3019. The fixing circlip 3020 is located below the guide rod 3012 to prevent the pin shaft 3019 from loosening and falling off due to rotation.

[0058] A mating section 3018 is provided on the side of the connecting rod 3014 away from the guide rod 3012. The mating section 3018 is an inclined plane cut along the axial direction of the connecting rod 3014. The mating section 3018 of the adjustment component 301 matches the corresponding push block 102, and the push block 102 abuts against the mating section 3018.

[0059] One end of the connecting rod rotating shaft 3015 is fixedly connected to the fixed bottom plate 201, and the other end is rotatably connected to the connecting rod 3014.

[0060] Working principle: Place the battery cell on the feeding plate 101. The gravity of the battery cell itself causes the feeding plate 101 to press down, driving the push block 102 to press down.

[0061] After the push block 102 presses down, it pushes the connecting rod 3014 to rotate with the connecting rod rotating shaft 3015 as the rotation axis. Among them, the mating section 3018 rotates in the direction close to the positioning block mounting plate 302, and one end of the connecting rod 3014 close to the guide rod 3012 rotates in the direction away from the positioning block mounting plate 302.

[0062] The rotation of the connecting rod 3014 drives the guide rod 3012 to move in the direction close to the feeding plate 101. The spring 3016 is compressed under force. The guide rod 3012 drives the positioning block mounting plate 302 and the adjustment positioning block 303 to move in the direction close to the battery cell to contact the battery cell, perform centering positioning on the battery cell, and subsequent operations can be carried out on the battery cell.

[0063] After the operation is completed, the battery cell is taken out. The spring 3016 is no longer stressed and resets, driving the guide rod 3012 to move away from the feeding plate 101 until the guide rod 3012, the positioning block mounting plate 302, and the adjusting positioning block 303 return to their initial positions.

[0064] The guide rod 3012 drives the connecting rod 3014 to rotate about the connecting rod rotating shaft 3015. Among them, the mating section 3018 rotates away from the positioning block mounting plate 302, and the end of the connecting rod 3014 close to the guide rod 3012 rotates towards the positioning block mounting plate 302.

[0065] The rotation of the mating section 3018 pushes the push block 102 to rise, driving the feeding plate 101 to rise to the initial position.

By cooperating with the feeding mechanism 1, the battery cells placed on the feeding mechanism 1 can complete their own centering positioning by their own gravity, without the need to provide an additional power source, and the overall structural design cost is reduced.

[0069] A plurality of weight reduction holes are provided on the feeding plate 101 to reduce the loss of force when the spring 3016 drives the feeding plate 101 to reset, and extend the service life of the spring 3016.

[0070] The positioning block mounting plate 302 is connected to the adjusting assembly 301. Two adjusting assemblies 301 are symmetrically connected to the positioning block mounting plate 302 of the long side positioning unit, improving the stability when the adjusting positioning block 303 positions the battery cell.

[0071] A snap ring 3013 is provided on the side of the adjusting assembly bearing seat 3011 away from the positioning block mounting plate 302 for maintaining the initial position of the guide rod 3012. A fixed snap ring 3020 is provided on the pin shaft 3019, and the fixed snap ring 3020 is located below the guide rod 3012 to prevent the pin shaft 3019 from loosening and falling off due to rotation.
