Description

Technical Field

[0001] This utility model relates to the field of battery separator production technology, and in particular to an automatic marking and verification device for separator cutting. Background Technology

[0002] Battery separators are porous materials that play a crucial role in batteries. They primarily isolate the positive and negative electrodes while allowing ions to pass through for electrochemical reactions. As a thin film material located between the positive and negative electrodes, the separator's main function is to prevent short circuits caused by direct contact between the electrodes, while allowing ions in the electrolyte to migrate freely during charging and discharging, thus ensuring normal battery operation. The slitting and marking of battery separators is a vital step in battery production. Proper slitting controls the dimensional accuracy and edge quality of the separator, reducing burrs and cracks, thereby improving the adhesion between the separator and the electrodes and contributing to enhanced battery performance, such as preventing short circuits and improving charging and discharging efficiency. During battery production, appropriate markings, such as production batch number, model, and production date, are affixed to the separator for easy identification and management. These markings help companies trace product quality.

[0003] In the existing technology, the marking process of battery separators requires the use of existing inkjet marking machines, and operators need to change the ink regularly. In order to facilitate the operation of operators, we propose an automatic marking and verification device for separator cutting. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 The automatic marking and verification device for diaphragm slitting includes a workbench 1, with a marking box 3 fixedly connected to the upper end of the workbench 1. The workbench 1 is made of high-strength steel to ensure the stability of the overall structure. Multiple conveying rollers 2 are fixedly connected to the upper end of the workbench 1. A through groove is provided through the marking box 3, and a receiving plate 8 is installed in the through groove. The receiving plate 8 is anodized to improve wear resistance and corrosion resistance. A lifting device is fixed to the lower end of the receiving plate 8. The lifting device includes multiple guide rods 11 fixedly connected to the lower end of the receiving plate 8. The guide rod 11 is made of stainless steel and the surface is polished to reduce friction. Guide grooves are provided through the side wall of the marking box 3 and the workbench 1 at the corresponding position. Multiple guide rods 11 are slidably connected through each guide groove. A base 9 is fixedly connected to the lower end of the workbench 1 at the corresponding position. An operating groove is provided through the base 9. An adjusting screw 10 is threaded through the inner wall of the operating groove. The tail end of the adjusting screw 10 passes through the side wall of the workbench 1 and the marking box 3 and is rotatably connected to the lower end of the receiving plate 8.

[0020] A device base 4 is fixedly connected to the upper end of the marking box 3. The marking box 3 and the device base 4 share a common mounting point for the inkjet printer body. The inkjet printer body is equipped with a high-precision printhead to ensure printing quality. A material trough is installed through the upper end of the device base 4, and a material replenishment device is installed inside the trough. The material replenishment device includes two ink cartridges 6 installed in the material trough. The lower ends of both ink cartridges 6 are fixedly connected to feed pipes 13. The lower ends of both feed pipes 13 are connected to the feed inlet of the inkjet printer body. A filter screen is installed at the feed inlet to prevent impurities from entering the printhead. Each ink cartridge 6 has a cover 15 at its top. A liquid level sensor 14 is installed inside each cover 15. Both liquid level sensors 14 are located inside the ink cartridge 6. The liquid level sensors 14 adopt a high-sensitivity design to ensure accurate detection of the remaining ink level. Two sensor indicator lights 16 are fixedly connected to the top of each cover 15. The two sensor indicator lights 16 on the same cover 15 are connected to the corresponding liquid level sensors 14 via signal. The sensor indicator lights 16 use LED light sources, which are energy-saving, environmentally friendly, and have a long lifespan.

[0021] Two sliding grooves are provided through the side wall of the top cover 7. Metal sheets are fixedly connected to the inner wall of each sliding groove. Magnetic sheets 17 are fixedly connected to the side walls of each of the two ink cartridges 6. The positions of the two magnetic sheets 17 correspond to the positions of the two metal sheets.

The handles 5 are ergonomically designed, comfortable to grip, and easy for operators to quickly open and close the top cover.

[0023] In use, the diaphragm enters the marking chamber 3 sequentially through multiple conveying rollers 2. The inkjet printer body, located at the device base 4, marks the diaphragm sequentially under the control of a relevant controller in the prior art. Rotating the corresponding adjusting screw 10 can drive the receiving plate 8 to move up and down within the marking chamber 3, reducing the vibration amplitude of the diaphragm and preventing damage. When the ink in one of the ink cartridges 6 is used up, the corresponding indicator light 16 will light up with the corresponding color light under the signal transmission of the corresponding liquid level sensor 14, reminding the operator to replace the ink cartridge 6 in time. When replacing, the operator presses down the ink cartridge 6 that does not need to be replaced, so that the corresponding magnetic sheet 17 disengages from the metal sheet on the top cover 7, allowing the inkjet printer body to continue working without affecting its normal operation.
