Description

Technical Field

[0001] The utility model relates to the technical field of conductive film production, in particular to an auxiliary installation mechanism for an evaporation boat. Background Art

[0002] Conductive film is a polymer material with metal on the surface. It is widely used in lithium-ion batteries and is mainly used as a battery current collector in lithium-ion batteries. Existing conductive metal films are mostly prepared by vacuum evaporation process. Vacuum evaporation refers to evaporating the coating material (or film material) by a certain heating evaporation method under vacuum conditions, so that the coating material is vaporized and the vaporized particles fly to the substrate surface and condense into a film.

[0003] The vacuum evaporation process has been widely used in the existing thin film production. In order to enable vacuum evaporation, the material to be evaporated needs to be heated. In the prior art, an evaporation boat is generally used to hold the material to be evaporated. The evaporation boat is mostly clamped and fixed on the vacuum evaporation equipment. Specifically, the vacuum evaporation equipment includes an evaporation tank, and a fixed electrode and a movable electrode are arranged in the evaporation tank. The movable electrode is elastically arranged, that is, the movable electrode can move based on the evaporation tank, and can be reset and moved under the action of elasticity. When installing the evaporation boat, an external force drives the movable electrode to move and increase the distance between it and the fixed electrode. After the evaporation boat is placed, the external force disappears, and the movable electrode is elastically reset to clamp the evaporation boat, so as to complete the vacuum evaporation.

[0004] When clamping the evaporation boat, a crowbar is required, and the lower end of the crowbar is pressed against the bottom of the fixed chuck, and the middle part of the crowbar is pressed against one side of the movable chuck, so as to press the movable chuck into the vacuum evaporation equipment. For example, utility model CN219772227U discloses an evaporation boat loading crowbar, including two spaced-apart legs, a connecting rod fixedly connecting the two legs, and a crowbar arm fixed at the bottom end on the connecting rod, the spacing between the two legs matches the size of the evaporation boat, and the crowbar drives the two legs to press the movable chuck along the two ends of the outer side of the end face of the movable chuck, so that the movable chuck is pressed into the vacuum evaporation equipment, so that the evaporation boat is placed between the movable chuck and the fixed chuck through the gap between the two legs, so that the movable chuck is evenly stressed when being pressed, and radial deviation caused by uneven stress when the movable chuck is pressed is avoided, thereby ensuring that the movable chuck always maintains good contact with the evaporation boat.

[0005] However, it was found during the production process that using a crowbar could easily damage the electrode and reduce the service life of the vacuum evaporation equipment. Utility Model Content

[0006] In order to overcome the deficiencies of the prior art, the utility model provides an auxiliary installation mechanism for an evaporation boat, which facilitates the installation of the evaporation boat by means of a foot pedal, can reduce electrode damage, and increase the service life of the vacuum evaporation equipment.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] An auxiliary installation mechanism for an evaporation boat comprises a support plate, a movable plate, an elastic member and a hinged plate, wherein the movable plate is arranged on the upper side of the support plate and is slidably connected to the support plate, one end of the hinged plate is hinged to the support plate, and the other end is in sliding contact with the movable plate, and the hinged plate is used to drive the movable plate to move when it rotates downward, and the movable plate can push the movable electrode to move when it moves, and the movable plate is connected to the elastic member, and the elastic member provides an elastic force to drive the movable plate to reset and move.

[0009] As a further improvement of the above technical solution, a hinge groove is provided on the support plate, and one end of the hinge plate is hinged to the side wall of the hinge groove through a hinge shaft.

[0010] As a further improvement of the above technical solution, a roller is installed at the other end of the hinged plate, and the roller is arranged in close contact with the movable plate.

[0011] As a further improvement of the above technical solution, a slide groove is arranged on the support plate, a sliding block is slidably connected in the slide groove, and the sliding block is fixedly connected to the bottom of the movable plate.

[0012] As a further improvement of the above technical solution, the shape of the slide groove and the slider is T-shaped.

[0013] As a further improvement of the above technical solution, the elastic member includes a spring, which is arranged in the slide groove, one end of the spring is connected to the side wall of the slide groove, and the other end of the spring is connected to the slider.

[0014] As a further improvement of the above technical solution, a foot pedal is connected to the top of the hinged plate, and a support plate is connected between the foot pedal and the hinged plate.

[0015] As a further improvement of the above technical solution, the support plate is placed on the bottom of the evaporation tank through a support seat.

[0016] As a further improvement of the above technical solution, the support seat includes an adjustment seat and a screw rod, a threaded hole is provided in the adjustment seat, the lower section of the screw rod rotates in the threaded hole, and the top end of the screw rod is fixedly connected to the bottom surface of the support plate.

[0017] As a further improvement of the above technical solution, a handle is provided on the support plate.

[0018] The beneficial effects of the utility model are as follows: by stepping on the hinged plate, the hinged plate is rotated downward, and the free end of the hinged plate pushes the movable plate to move outward. When the movable plate moves, it pushes the movable electrode to move, thereby increasing the distance between the movable electrode and the fixed electrode, which is convenient for installing the evaporation boat. After the evaporation boat is installed, the external force on the hinged plate is cancelled, and the movable plate is driven to move back under the action of the elastic member. When the movable plate moves back, it drives the hinged plate to rotate upward to complete the reset; at the same time, the movable electrode rebounds, thereby clamping the evaporation boat. In the installation of the evaporation boat, compared with the prior art method of using a crowbar, the utility model uses a pedaling method to facilitate the installation of the evaporation boat. Only the side walls of the movable plate and the movable electrode are in contact, which can reduce electrode damage and increase the service life of the vacuum evaporation equipment.

[0027] Reference Figure 1-5 An embodiment of the utility model provides an evaporation boat auxiliary installation mechanism 5, which is used to install the evaporation boat 4 between the fixed electrode 2 and the movable electrode 3 in the evaporation tank 1. In a specific embodiment, the evaporation boat auxiliary installation mechanism 5 includes a support plate 52, a fixed plate 53, a movable plate 54, an elastic member and a hinge plate 55. A handle 57 is fixed on the support plate 52 to facilitate the staff to place the evaporation boat auxiliary installation mechanism 5 in the evaporation tank 1 or take it out. The fixed plate 53 and the movable plate 54 are respectively arranged at the two ends of the upper side of the support plate 52, and the fixed plate 53 is fixedly connected to the support plate 52, and the movable plate 54 is slidably connected to the support plate 52. One end of the hinged plate 55 is hinged to the support plate 52, and the other end of the hinged plate 55 is in sliding contact with the movable plate 54. When the hinged plate 55 rotates downward, it can drive the movable plate 54 to move away from the fixed plate 53. The projection of the movable plate 54 and the end of the movable electrode 3 in the height direction has an overlapping part, that is, the movable plate 54 can abut against the movable electrode 3 after moving, thereby pushing the movable electrode 3 to move, increasing the distance between the movable electrode 3 and the fixed electrode 2, so as to facilitate the installation of the evaporation boat 4.

[0028] In this embodiment, refer to Figure 3 and Figure 5 A support seat 51 is provided at the bottom of the support plate 52, and the evaporation boat auxiliary installation mechanism 5 is placed at the bottom of the evaporation tank 1 through the support seat 51. In order to improve the stability of the evaporation boat auxiliary installation mechanism 5 after placement, two support seats 51 are provided.

[0029] Furthermore, the support seat 51 includes an adjustment seat 511 and a screw 512. A threaded hole is set in the adjustment seat 511. The lower section of the screw 512 rotates in the threaded hole. The top of the screw 512 is fixedly connected to the bottom surface of the support plate 52. By adjusting the length of the screw 512 screwed into the threaded hole, the height of the support plate 52 can be adjusted, so that the height of the movable plate 54 is adapted to the height of the movable electrode 3, so that the movable plate 54 can stably push the movable electrode 3.

[0030] In this embodiment, refer to Figure 2-5 The support plate 52 is provided with a hinge slot 521, one end of the hinge plate 55 is hinged to the side wall of the hinge slot 521 through a hinge shaft 58, and the support plate 52 can rotate up and down along the hinge shaft 58. The other end of the hinge plate 55 is provided with a roller 56, and the roller 56 is arranged in close contact with the moving plate 54. The roller 56 rolls on the moving plate 54, and when the external force drives the support plate 52 to rotate downward, the moving plate 54 is pushed to move; when the external force is eliminated, the moving plate 54 moves back to drive the support plate 52 to rotate upward.

[0031] Furthermore, a foot pedal 551 is connected to the top of the hinged plate 55, and a support plate 552 is connected between the foot pedal 551 and the hinged plate 55. The provision of the support plate 552 facilitates increasing the height of the foot pedal 551, thereby facilitating manual application of external force on the foot pedal 551 outside the evaporation tank 1, and the foot pedal 551 and the hinged plate 55 rotate downward as a whole.

[0032] In this embodiment, refer to Figure 3-5 The support plate 52 is provided with a slide groove 522, in which a slider 523 is slidably connected. The slider 523 is fixedly connected to the bottom of the movable plate 54, that is, the movable plate 54 can move on the support plate 52 through the slider 523 and the slide groove 522.

[0033] Furthermore, the shape of the slide groove 522 and the slider 523 is T-shaped, and can also be other shapes such as Y-shaped, arc-shaped, etc., to avoid deflection of the movable plate 54 when sliding, and improve the stability of the movable plate 54 sliding on the support plate 52.

[0034] In this embodiment, refer to Figure 3-4The elastic member includes a spring 524, and the spring 524 is arranged in the slide groove 522. One end of the spring 524 is connected to the side wall of the slide groove 522, and the other end of the spring 524 is connected to the slider 523. When the hinge plate 55 rotates downward to drive the movable plate 54 to move outward, the spring 524 is stretched. When the external force disappears, the spring 524 will rebound to a natural state under the action of the elastic force, thereby driving the movable plate 54 to move back. When the movable plate 54 moves back, it drives the hinge plate 55 to rotate upward to complete the reset.

[0035] In other embodiments, the spring 524 may be connected between the fixed plate 53 and the movable plate 54. Similarly, when the hinge plate 55 is in the initial state, the spring 524 is in a natural state.

[0036] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
