[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For the auxiliary bracket for lithium battery assembly, by setting the adjusting stud, moving seat, top rack and placing rack, loosen the locking nut sleeve to control the rotation of the adjusting stud, control the moving seat to slide on the surfaces of the adjusting stud and the two groups of limiting sliding rods, so that the top rack rotates between the rotating rack and the connecting rack, thereby jacking up one side of the placing rack, making the placing rack tilt at a certain angle on the top of the base, and obliquely placing the lithium battery into the placing groove on the top of the placing rack, preventing the lithium battery from sliding out from one end of the placing groove, and at the same time making the lithium battery slide down to the same height inside the placing groove, ensuring that multiple lithium batteries stuck inside the placing groove can be flush, and there will be no misalignment or deviation during assembly.

[0013] 2. For the auxiliary bracket for lithium battery assembly, by setting the placing groove, blocking rack, pressing rack and pressing spring, the lithium battery is stuck inside the placing groove, push the lithium battery to move inside the placing groove, make one end of the lithium battery tightly abut against the pressing rack to jack up the pressing rack away from the placing rack until the lithium battery is tightly attached to the surface of the blocking rack, and under the rebounding action of the pressing spring, press down the pressing rack to tightly press against the surface of the lithium battery, thereby tightly pressing and fixing the lithium battery between the placing groove and the pressing groove, ensuring that the lithium battery will not randomly fall out from the inside of the placing groove during the assembly of the lithium battery.

Detailed implementation mode

[0018] The technical solution of this patent will be further described in detail below in conjunction with the specific implementation mode.

[0019] As Figures 1-3 shown, the utility model provides a technical solution: an auxiliary bracket for lithium battery assembly, including a base 1. Fixed suction cups 2 are fixedly installed at the four corners of the bottom of the base 1. A rectangular groove 3 is provided at the top of the base 1. Limit slide bars 4 are symmetrically and fixedly installed on both sides of the inner wall of the rectangular groove 3. By providing the limit slide bars 4, when the moving seat 9 slides on the surfaces of the two limit slide bars 4, it is ensured that the moving seat 9 will not tilt or deflect during the moving process.

[0020] An adjusting screw 5 is rotatably installed at the central position between the two limit slide bars 4 inside the rectangular groove 3. One end of the adjusting screw 5 passes through the base 1 and is fixedly installed with a locking stud 6. A locking nut sleeve 7 is provided on the surface of the locking stud 6. A cross plate 8 is fixedly installed at the end of the locking stud 6 away from the adjusting screw 5. Due to the presence of the locking nut sleeve 7, the locking nut sleeve 7 is tightened against the surface of the base 1, thereby locking and fixing the locking stud 6 to ensure that the adjusting screw 5 will not rotate randomly inside the rectangular groove 3.

[0021] A moving seat 9 is provided on the surfaces of the adjusting screw 5 and the two limit slide bars 4 inside the rectangular groove 3. By providing the adjusting screw 5, the adjusting screw 5 is controlled to rotate, so that the moving seat 9 slides on the surfaces of the adjusting screw 5 and the two limit slide bars 4.

[0022] Rotating frames 10 are fixedly installed at both ends of one side of the moving seat 9. A top frame 11 is rotatably installed at the top of the rotating frame 10. Connecting frames 12 are rotatably installed at the ends of the two top frames 11 away from the rotating frames 10. A placing frame 13 is rotatably installed on one side of the top of the base 1, and one side of the bottom of the placing frame 13 is fixedly connected to the connecting frame 12. Due to the presence of the top frame 11, when the moving seat 9 moves inside the rectangular groove 3, the top frame 11 rotates between the rotating frame 10 and the connecting frame 12, thereby lifting and tilting one side of the bottom of the placing frame 13 close to the connecting frame 12 to adjust the tilting angle of the placing frame 13 on the top of the base 1.

[0023] Five groups of placement grooves 14 are equidistantly arranged at the top of the placement rack 13. One side of the top of the placement rack 13 is fixedly installed with a blocking rack 15, and the shape of the blocking rack 15 corresponds to that of the placement groove 14. By providing the blocking rack 15, when multiple groups of lithium batteries are inserted into the corresponding placement grooves 14 and closely attached to one side of the blocking rack 15, it is ensured that the multiple groups of lithium batteries are flush with each other.

[0024] At the ends of both sides of the placement rack 13 away from the blocking rack 15, fixing plates 16 are respectively fixedly installed. A pressing rod 17 is slidably installed inside the fixing plate 16. The tops of the two pressing rods 17 pass through the fixing plate 16 and are fixedly installed with a pressing frame 20. The bottom end of the pressing rod 17 passes through the fixing plate 16 and is fixedly installed with an end plate 18. A pressing spring 19 is provided on the surface of the pressing rod 17 between the fixing plate 16 and the end plate 18. Due to the provision of the pressing spring 19 and the pressing frame 20, under the rebounding action of the pressing spring 19, the end plate 18 is pressed down away from the fixing plate 16, so that the pressing frame 20 approaches the placement rack 13, and the lithium battery is clamped and fixed between the pressing frame 20 and the placement rack 13.

[0025] Five groups of pressing grooves 21 are equidistantly arranged at the bottom of the pressing frame 20, and the positions of the pressing grooves 21 correspond to those of the placement grooves 14. One side of the inner top of the pressing groove 21 is beveled. By providing the pressing groove 21, when the lithium battery passes through the bottom of the pressing groove 21, the beveled pressing groove 21 facilitates clamping and fixing the lithium battery between the pressing groove 21 and the placement groove 14.

[0026] The working principle of the present utility model is as follows:

[0027] After moving the base 1 to a suitable position on the top of the assembly table, when pressing the fixed suction cup 2, the base 1 is adsorbed and fixed on the top of the assembly table. Loosen the locking nut 7 to control the cross plate 8 to drive the locking stud 6 and the adjusting screw 5 to rotate, and adjust the position of the moving seat 9 inside the rectangular groove 3, so that the top frame 11 rotates between the rotating frames 10 at both ends of the moving seat 9 and the connecting frame 12 at the bottom of the placement rack 13, thereby lifting one side of the placement rack 13 close to the locking nut 7 until the placement rack 13 tilts at a certain angle on the top of the base 1. Then tighten the locking nut 7 to lock and fix the adjusting screw 5, so that the placement rack 13 does not fall when tilting at a certain angle on the top of the base 1. Place five groups of lithium batteries on the top of the placement grooves 14, and push the lithium batteries to slide inside the placement grooves 14 through the corresponding pressing grooves 21 until the lithium batteries are closely attached to the blocking rack 15 inside the placement grooves 14. Under the rebounding action of the pressing spring 19, the pressing frame 20 is pressed against the surface of the lithium battery, so that the five groups of lithium batteries can be flush and pressed inside the corresponding placement grooves 14, which is convenient for the assembler to assemble the five groups of lithium batteries.
