Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, in particular to a manual pressing type pole seat mechanism. Background Art

[0002] Conductive film is a polymer material with metal coated on the surface. It is widely used in lithium-ion batteries, and is mainly used as a battery current collector in lithium-ion batteries. The most commonly used method for producing conductive films is vacuum evaporation process. Vacuum coating is to place the film material in a vacuum coating chamber and heat it through an evaporation source to evaporate it. The evaporated particles escape from the surface of the evaporation source and condense on the surface of the substrate to form a film. Vacuum coating is usually resistive heating. The evaporation boat is fixed between the positive and negative electrodes, and the material to be evaporated is placed in the evaporation boat. Current is passed through the electrodes, and the current flows through the evaporation boat. The evaporation boat heats up to evaporate the material to be evaporated.

[0003] In order to quickly replace the evaporation boat, the existing evaporation boat device usually fixes the evaporation boat between the positive and negative motors by clamping, such as a clamping device for evaporation boat with publication number CN116397197A. Although this method simplifies the operation to a certain extent, it still has some significant defects in actual use.

[0004] First, although this clamping method is convenient for replacement, due to the limitation of clamping force and stability, the evaporation boat may fall off due to vibration, temperature change or other external factors. Once the evaporation boat falls off, it will affect the normal operation of the vacuum coating machine and may even cause equipment damage and production interruption.

[0005] Secondly, the existing evaporation boat clamping device usually uses mechanical or electric clamps. Due to mechanical wear and long-term use of these clamps, their clamping force may change, resulting in unstable fixation of the evaporation boat. In this case, the clamps need to be checked and adjusted regularly, which increases maintenance costs and time costs. Utility Model Content

[0029] See also Figures 1 to 3 The present embodiment provides a manual clamping type pole seat mechanism, including an evaporation tank 1, a positive pole seat 2, a negative pole seat 3, an evaporation boat 4 and a clamping assembly 5. The evaporation tank 1 is provided with pole seat holes 101 on opposite sides. One end of the positive pole seat 2 and the negative pole seat 3 respectively penetrates through the two pole seat holes 101 and is arranged in the evaporation tank 1. The positive pole seat 2 and the negative pole seat 3 are arranged at intervals, and the ends close to the positive pole seat 2 and the negative pole seat 3 are provided with placement grooves 201. Both ends of the evaporation boat 4 are fixed in the two placement grooves 201 through the clamping assembly 5. Among them, the clamping assembly 5 includes a butterfly nut 501, a screw 502 and a pressing block 503. The lower end of the screw 502 is fixed outside the placement groove 201, and the upper end of the screw 502 passes through the pressing block 503 and is threadedly connected with the butterfly nut 501. When the butterfly nut 501 is manually turned to tighten the butterfly nut 501, the pressing block 503 presses the corresponding end of the evaporation boat 4 into the placement groove 201, thereby fixing the evaporation boat 4 between the positive pole seat 2 and the negative pole seat 3. When the butterfly nut 501 is manually turned in the opposite direction, the pressing block 503 loosens the corresponding end of the evaporation boat 4, releasing the squeezing of the corresponding end of the evaporation boat 4, so that the evaporation boat 4 can be easily taken out of the placement groove 201. The setting of the above-mentioned pressing assembly 5 can not only realize the evaporation boat 4 is firmly fixed between the positive pole seat 2 and the negative pole seat 3, but also facilitate the rapid replacement of the evaporation boat 4 without the need for tools, thereby reducing time costs and improving production efficiency and quality; the structure is simple, no regular inspection and adjustment are required, and the maintenance cost is low.

[0030] See also Figure 3In this embodiment, each clamping assembly 5 has two butterfly nuts 501 and two screw rods 502, the lower ends of the two screw rods 502 are respectively fixed on the outer sides of the placement groove 201, the two butterfly nuts 501 are respectively threadedly connected to the upper ends of the screw rods 502, and the two ends of the pressing block 503 are respectively provided with through holes 5031 for the screw rods 502 to pass through. By providing two screw rods 502 and butterfly nuts, it can be ensured that the two ends of the pressing block 503 are evenly stressed, so as to better press the corresponding end of the evaporation boat 4 into the placement groove 201. In addition, a buffer pad 504 is provided between the butterfly nut 501 and the pressing block 503, and the buffer pad 504 plays a buffering role to prevent the butterfly nut 501 from crushing the pressing block 503.

[0031] See also Figure 3 In this embodiment, a pressing groove 5032 matching the upper surface of the end of the evaporation boat 4 is provided at the bottom of the pressing block 503. The setting of the pressing groove 5032 enables the pressing block 503 to better press the corresponding end of the evaporation boat 4 into the placement groove 201.

[0032] See also Figure 3 In this embodiment, the upper surface of the end of the evaporation boat 4 and the top of the pressing groove 5032 are arranged in an inverted V shape, and the lower surface of the end of the evaporation boat 4 and the bottom of the placement groove 201 are arranged in a V shape. The above arrangement increases the contact area between the end of the evaporation boat 4 and the positive electrode seat 2 and the negative electrode seat 3, and improves the stability of the current. In addition, graphite paper 6 is arranged between the evaporation boat 4 and the placement groove 201 and the pressing groove 5032. The graphite paper 6 can enhance the conductivity between the positive electrode seat 2, the evaporation boat 4 and the negative electrode seat 3, thereby accelerating the evaporation efficiency.

Due to the metal dust that will fall during the evaporation process, the first insulating sleeve 7 and the insulating sleeve 8 can prevent the evaporation tank 1 and the positive electrode seat 2 and the negative electrode seat 3 from being connected by metal dust, thereby causing a short circuit. In addition, a second insulating sleeve 9 is provided in the pole seat hole 101 of the evaporation tank 1. The second insulating sleeve 9 can well separate the evaporation tank 1 from the positive electrode seat 2 and the negative electrode seat 3, prevent the evaporation tank 1 from being electrically conductive with the positive electrode seat 2 and the negative electrode seat 3, and can also seal the gap between the pole seat hole 101 and the positive electrode seat 2 and the negative electrode seat 3, thereby reducing the probability of metal dust being deposited in the gap. Preferably, the first insulating sleeve 7 is a mica insulating sleeve, and the insulating sleeve 8 is a polytetrafluoroethylene insulating sleeve.
