Description

Technical Field

[0001] The invention relates to the technical field of thickness detection, and in particular to a multifunctional detection device for lithium battery separator production. Background Art

[0002] Battery separator refers to a layer of separator material between the positive and negative electrodes of the battery. It is a very critical part of the battery and has a direct impact on the safety and cost of the battery. During production, the battery separator needs to be coated with a layer of coating. After the coating is applied, it needs to be dried by drying equipment. After drying, the battery separator needs to be measured by laser measuring equipment for width, thickness, etc. to avoid defects in the quality of the battery separator product after drying. The utility model with the existing publication number CN218443759U discloses a battery diaphragm thickness detection device, including a frame and a cabinet door, an indicator gauge is arranged at the lower part of the hydraulic rod, the hydraulic rod and the indicator gauge are connected to each other through a connecting plate, and a laser probe is arranged at the bottom of the lower end of the indicator gauge. The battery diaphragm thickness detection device uses a mechanized detection method to reduce the detection error. Due to the continuous production of battery diaphragms, the battery diaphragms that have just been dried will have size changes. In order to reasonably control the quality of battery diaphragms, common laser size measuring equipment is mostly installed at the rear end of the production line of the drying equipment. When the battery diaphragm passes by, direct online measurement is performed by the laser measuring equipment.

[0023] Embodiment 2: On the basis of embodiment 1, the horizontal sliding stability of the movable support plate 5 is enhanced. The movable support plate 5 is provided with two oil chambers 39 at the lower end of the diverter groove 24. The upper ends of the two oil chambers 39 are connected to the diverter groove 24 through a one-way valve. The upper end of the slider 35 sleeved on the slide rail 4 is provided with an oil drip hole. The lower ends of one side of the two oil chambers 39 are respectively connected to the two oil drip holes and are provided with an oil delivery pipe 36. The upper ends of both sides of the movable support plate 5 are provided with a clearance groove 31. The clearance groove 31 is provided. The slots 31 are connected to the output slots 26 and are provided with blocking slots. A blocking rod is provided in the blocking slot through a partition plate for horizontal movement.

When the slide rail 4 needs to be moved During the lubrication operation, the blocking piston 32 blocks the output groove 26, the push block 33 retracts into the blocking groove, the push rod 40 is inserted into the clearance groove 31 and contacts the push block 33. When the slide rail 4 and the slider 35 need to be lubricated, the control screw 38 controls the movable support plate 5 to move to the position of the push rod 40. During normal detection, the movable support plate 5 can complete the normal detection without reaching the position of the push rod 40. When the two push rods 40 are inserted into the clearance groove 31 and push the push rod 40, the push rod 40 is pushed into the clearance groove 31. When the block 33 and the blocking piston 32 move, the blocking piston 32 blocks the output groove 26. At this time, the gas in the diverter groove 24 cannot be sent into the spacing groove 28 through the output groove 26. Then, as the air pressure in the diverter groove 24 gradually increases, the high-pressure gas pushes the one-way valve of the oil chamber 39 to enter it. Then, after the lubricating oil in the oil chamber 39 is pressurized, it flows to between the slider 35 and the slide rail 4 through the oil delivery pipe 36, lubricating the sliding of the two, thereby improving the smoothness and accuracy of the left and right sliding during detection.

When the slide rail (4) needs to be lubricated, the blocking piston (32) blocks the output groove (26), the push block (33) retracts into the blocking groove, and the push-in rod (40) is inserted into the clearance groove (31) and contacts the push block (33).
