Description

Technical Field

[0001] The utility model relates to the technical field of two-stage transmission, in particular to a two-stage transmission type positioning device for narrow spaces. Background Art

[0002] The lithium-ion battery separator is an important component in a lithium-ion battery. The lithium-ion battery separator is a porous thin film material that plays a role in separating the positive and negative electrodes in the battery and preventing internal short circuits in the battery. After the production of the lithium-ion battery separator, the separator roll needs to be packaged. As disclosed in Chinese Patent CN115626316A, a fully automatic anti-magnetic packaging line for lithium battery separators includes: a coil loading mechanism, which includes a material rack and a coil loading manipulator, and the separator coil is placed on the material rack; a coil coating mechanism, which includes a double-speed chain conveyor line, a coil loading jig, a central paper tube bagging machine, and a coil bagging machine; a tube inserting mechanism, which includes a support frame, an X-direction moving module, a Z-direction moving module, an inserting tube assembly, and a tube inserting elevator; a coil unloading mechanism, which includes an unloading manipulator and an unloading roller conveyor line; a packaging material feeding mechanism, which includes a packaging material roller loading line, a disk feeding assembly, and a packaging material loading and unloading manipulator, and plastic packaging boxes are stacked on the packaging material roller loading line.

[0003] During the packaging process of the lithium-ion battery separator, multiple separator rolls are stacked and packaged. In order to position multiple separator rolls, it is necessary to insert a paper tube into the center of the stacked multiple separator rolls to achieve the positioning of the separator rolls.

[0004] In order to ensure that the paper tube can be smoothly inserted into multiple separator rolls and avoid position offset between the upper and lower separator rolls, it is necessary to use a positioning rod instead of the paper tube to pre-position multiple separator rolls in advance. However, when the positioning rod is inserted into the central through holes of multiple separator rolls stacked on the conveyor line, due to the limited space below the conveyor line, it is not convenient to arrange a long-stroke driving mechanism, resulting in a limited rising height of the positioning rod when positioning multiple separator rolls, and multiple separator rolls cannot be effectively positioned. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a two-stage transmission type positioning device for narrow spaces to solve the problem of limited rising height of the positioning rod when the space below the roller conveyor line is limited.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: A two-stage transmission type positioning device for narrow spaces includes:

[0012] As a further description of the above technical solution:

[0013] The supporting plate is provided with kidney-shaped holes, and bolts pass through the kidney-shaped holes and then connect to the support feet.

[0014] As a further description of the above technical solution:

[0015] An anti-tilting bracket is arranged on the supporting plate. The anti-tilting bracket is triangular, and the anti-tilting bracket is fixedly installed on the back of the mounting frame.

[0016] As a further description of the above technical solution:

[0017] The second connecting plate is fixedly installed on the synchronous belt through a belt pressing plate. The second connecting plate and the belt pressing plate are symmetrically arranged on both sides of the synchronous belt, and the belt pressing plate is provided with tooth grooves matching the shape of the synchronous belt.

During the rising process of the lifting seat, since the position of the first connecting plate remains unchanged, the synchronous belt pulls the second connecting plate to rise, and the positioning rod rises a second time accordingly. Therefore, when the driving motor drives the lifting seat to rise a certain height, the positioning rod rises a double height, achieving two-stage transmission and ensuring the rising distance of the positioning rod under the condition of limited installation space height.

Mounting frame 21 is fixedly installed on frame 1, driving motor 22 is fixedly installed on mounting frame 21, the output end of driving motor 22 is connected to driving gear 221, lifting seat 23 is slidably connected to mounting frame 21, a rack 231 meshing with driving gear 221 is arranged on one side of lifting seat 23, the synchronous belt mechanism is fixedly installed on lifting seat 23, the synchronous belt mechanism includes synchronous belt 24, a first connecting plate 211 is arranged on mounting frame 21, first connecting plate 211 is fixedly installed on synchronous belt 24, and a second connecting plate 241 is also arranged on synchronous belt 24;

[0037] Positioning rod 3, which is slidably connected to lifting seat 23, and the end of second connecting plate 241 is fixedly installed on positioning rod 3.

[0038] Frame 1 includes support feet 11 and a supporting plate 12. Supporting plate 12 is fixedly installed on the top of support feet 11, and mounting frame 21 is fixedly installed on supporting plate 12. In addition, a waist-shaped hole 121 is provided on supporting plate 12, and bolts pass through waist-shaped hole 121 and then connect to support feet 11, which is convenient for adjusting the distance between the two support feet 11 and realizing position avoidance when the installation conditions are limited.

[0039] An anti-tilting bracket 13 is arranged on supporting plate 12. Anti-tilting bracket 13 is triangular, and anti-tilting bracket 13 is fixedly installed on the back of mounting frame 21. The triangular anti-tilting bracket 13 can effectively prevent the installation of mounting frame 21 from tilting, ensure the smooth vertical lifting of lifting seat 23, and ensure the positioning effect of positioning rod 3.

[0040] The second connecting plate 241 is fixedly installed on the synchronous belt 24 through the belt pressing plate 242. The second connecting plate 241 and the belt pressing plate 242 are symmetrically arranged on both sides of the synchronous belt 24. The belt pressing plate 242 is provided with tooth grooves that match the shape of the synchronous belt 24. The synchronous belt 24 effectively fixes the second connecting plate 241 and effectively drives the positioning rod 3. The installation of the first connecting plate 211 is the same.

[0041] A plurality of groove-shaped photoelectric sensors 212 arranged in a straight line are provided on the mounting frame 21, and positioning stoppers 232 corresponding to the groove-shaped photoelectric sensors 212 in position are provided on the lifting seat 23, which is convenient for monitoring the upward travel distance of the positioning rod 3.

The positioning rod 3 installs the slide rail 32 through the installation groove 31, effectively hiding the slide rail 32 and avoiding affecting the positioning of the diaphragm roll.

[0043] Working principle: When the positioning device under the roller conveyor line works, the positioning rod 3 passes through the gap between the rollers and then positions a plurality of stacked diaphragm rolls. During the specific positioning process, the driving motor 22 drives the driving gear 221 to rotate. The driving gear 221 drives the lifting seat 23 to rise through the rack 231. The positioning rod 3 rises once along with the lifting seat 23. During the rising process of the lifting seat 23, since the position of the first connecting plate 211 remains unchanged, the synchronous belt 24 pulls the second connecting plate 241 to rise, and the positioning rod 3 rises a second time. Therefore, when the driving motor 22 drives the lifting seat 23 to rise a certain height, the positioning rod 3 rises by a double height, realizing two-stage transmission and ensuring the rising distance of the positioning rod 3 under the condition of limited installation space height.
