[0007] Preferably, the elastic fixing component includes a connecting rod disposed on the side of the fixing cap, and a hook rod disposed on the tail end of the connecting rod away from the fixing cap, the hook rod having a channel inside. The bottom end of the fixed cylinder is provided with a guide rod that cooperates with the channel, and a positioning spring is provided on the outer periphery of the guide rod. The hook rod moves axially within the fixed cylinder and compresses the positioning spring during the movement.

[0008] Preferably, the outer periphery of the fixed cylinder is provided with a guide groove for the movement of the hook rod, and a positioning rotating groove is provided at the end of the guide groove so that the hook rod can rotate through the positioning rotating groove.

[0009] Preferably, the lower part of the support frame has two sets of through slots for moving the fixed cylinder, and the inner wall of the through slot is provided with a limiting plate so that the fixed cylinder can move axially linearly inside the through slot through the limiting plate.

[0010] Preferably, the outer periphery of the fixed cylinder is provided with a sliding groove that cooperates with the limiting plate, and the two sets of sliding grooves are symmetrically arranged so that the fixed cylinder can move on the side of the limiting plate through the sliding groove.

[0011] Preferably, the side wall of the molding machine has a groove at the positioning hole that mates with the hook rod, and an arc-shaped groove at the end of the groove that mates with the positioning slot, so that the hook rod can rotate to abut against the side of the arc-shaped groove.

[0015] The flexible fixing component can extend and engage with the positioning hole on the side wall of the battery separator molding machine to form a stable connection. Compared with rigid bolt connections, this method is better suited to the needs of rapid installation and greatly improves installation and commissioning efficiency.

[0016] The anti-slip rubber pads installed at the hook rod have an inclined design that allows them to fit tightly against the side wall of the arc-shaped groove, effectively preventing the hook rod from sliding during the application of force and further improving the stability and reliability of the fixation.

[0017] The markings on the fixed screw cap indicate the rotation angle, allowing operators to intuitively grasp the rotation angle of the screw cap, ensuring the accuracy and consistency of each disassembly and assembly operation, and improving operational convenience. Attached Figure Description

Detailed Implementation

[0020] To address the problem of existing technologies requiring multiple people to tighten multiple bolts, resulting in long downtime and reduced continuous production efficiency, this utility model provides a battery separator anti-warping structure fixing component. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] Please see Figure 1-7 This utility model provides a battery separator anti-warping structure fixing assembly, including: Support frame 1 is used to support the anti-warping structure of battery separator; the lower part of the support frame 1 is provided with two sets of through grooves 5 for moving the fixed cylinder 2, and the inner wall of the through groove 5 is provided with a limiting plate 6 so that the fixed cylinder 2 can move axially linearly inside the through groove 5 through the limiting plate 6.

[0022] The side wall of the molding machine has a groove 8 at the positioning hole 7 that mates with the hook rod 32, and an arc-shaped groove 9 at the end of the groove 8 that mates with the positioning rotating groove 22, so that the hook rod 32 can rotate to abut against the side of the arc-shaped groove 9.

[0023] Two sets of fixed cylinders 2 are respectively located at the lower part of the support frame 1 and pass through the support frame 1. The front end of the fixed cylinder 2 is used to insert into the positioning hole 7 on the side wall of the battery separator forming machine. The bottom end of the fixed cylinder 2 is provided with a guide rod 34 that cooperates with the channel 33. The outer periphery of the guide rod 34 is provided with a positioning spring 35. The hook rod 32 moves axially within the fixed cylinder 2 and compresses the positioning spring 35 during the movement.

[0024] The outer periphery of the fixed cylinder 2 is provided with a guide groove 21 for the movement of the hook rod 32, and a positioning rotating groove 22 is provided at the tail end of the guide groove 21 so that the hook rod 32 can rotate through the positioning rotating groove 22.

[0025] The outer periphery of the fixed cylinder 2 is provided with a sliding groove 23 that cooperates with the limiting plate 6, and the two sets of sliding grooves 23 are symmetrically arranged so that the fixed cylinder 2 can move on the side of the limiting plate 6 through the sliding groove 23.

[0026] The elastic fixing component 3 is housed within the fixing cylinder 2 and can extend from the front end of the fixing cylinder 2 to engage with the positioning hole 7. The elastic fixing component 3 includes a connecting rod 31 disposed on the side of the fixing cap 4. A hook rod 32 is disposed on the tail end of the connecting rod 31 away from the fixing cap 4. A channel 33 is opened inside the hook rod 32. An anti-slip pad 10 is disposed at the hook rod 32. The anti-slip pad 10 is arranged at an angle so that the anti-slip pad 10 rotates at the angle to abut against the side wall of the arc-shaped groove 9.

[0027] A fixing cap 4, located outside the fixing cylinder 2, is used to drive the elastic fixing component 3 to complete the snap-fit, thereby detachably fixing the support frame 1 to the battery separator forming machine. A mark 11 for indicating the rotation angle is provided on the fixing cap 4.

[0028] The working principle of the battery separator anti-warping structure fixing component provided by this utility model is as follows: the support frame 1 is placed on the side of the battery separator forming machine, so that the two sets of fixing cylinders 2 are respectively aligned with the positioning holes 7 on the side wall of the forming machine.

[0029] Slowly insert the front end of the fixed cylinder 2 into the positioning hole 7, ensuring that the fixed cylinder 2 can smoothly enter the positioning hole 7 and that the outer periphery of the fixed cylinder 2 is tightly fitted to the side wall of the molding machine.

[0030] Pressing the fixed cap 4 causes the hook rod 32 to move through the guide groove 21 within the fixed cylinder 2 via the transmission of the connecting rod 31 and the hook rod 32. Simultaneously, the positioning spring 35 is compressed until the hook rod 32 moves to the side of the positioning rotating groove 22. At this point, rotating the fixed cap 4 causes the hook rod to rotate through the positioning rotating groove 22 into the arc-shaped groove 9. The elastic force of the positioning spring 35 pushes the hook rod 32 outward, making it abut against the arc-shaped groove 9. The anti-slip rubber pad 10 at the hook rod 32 fits tightly against the side wall of the arc-shaped groove 9, thereby detachably fixing the support frame 1 to the battery separator forming machine.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
