Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery spraying equipment, and specifically discloses a lithium battery spraying and feeding device. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-hydrolyzed electrolyte solution. Lithium-ion batteries store and release electrical energy by moving lithium ions back and forth between the positive and negative electrodes. During discharge, lithium ions move from the negative electrode to the positive electrode, and during charging, lithium ions return to the negative electrode. In the lithium-ion battery manufacturing process, in order to prevent short circuits and leakage, improve battery performance, and ensure the normal use and safety of lithium-ion batteries, it is usually necessary to use a spraying device to spray an insulating coating on the outside of the lithium-ion battery. Among them, UV insulating coatings are widely used in the lithium-ion battery manufacturing field because of their rapid curing, environmental friendliness, and excellent insulation properties.

[0003] Chinese patent CN220329019U discloses a lithium battery coating and feeding mechanism, including a horizontal moving frame, a rotating device or a fixture. The horizontal moving frame is mounted on a horizontal plane or suspended upside down on a gantry frame. The rotating device is mounted on the horizontal moving frame and can drive the rotating device to move along its length. The fixture is mounted on the rotating device and can rotate horizontally along the axis of the rotating device. The fixture is used to place lithium batteries. In the specific spraying process, the fixture is moved onto the jig and fixed at its bottom or top. After the spraying devices located on one or both sides of the feeding mechanism have finished spraying the side wall of the lithium battery, the rotating device drives the jig to rotate, and the spraying device then sprays the unsprayed surface of the lithium battery. This allows for spraying of the circumference of the lithium battery in one go, effectively reducing the spraying blind area and improving the spraying efficiency. At the same time, it reduces the need for connecting mechanisms and lowers the production cost of the spraying equipment. However, the feeding mechanism does not have a coating curing function during use, which means that after the lithium battery is sprayed, it needs to be removed from the jig and placed in an additional curing device for curing. During the process of removing the lithium battery, the coating is very likely to separate from the lithium battery, affecting the quality and efficiency of the lithium battery spraying. Therefore, in order to solve the above problems, this utility model proposes a lithium battery spraying feeding device. Utility Model Content

[0004] The present invention aims to provide a lithium battery coating feeding device, which has the function of curing the coating on the outside of the lithium battery, preventing the coating from falling off during the user's handling of the lithium battery, ensuring the quality and efficiency of the coating spraying on the outside of the lithium battery, eliminating the need for additional curing equipment, saving investment in lithium battery coating equipment costs, and thus reducing the production cost of lithium batteries.

[0005] This utility model is achieved through the following technical solution:

[0006] A lithium battery coating and feeding device includes a base and a feeding mechanism. The feeding mechanism is located above the base, and two coating device bodies are located on both sides of the feeding mechanism. Both coating device bodies are connected to the base. A curing mechanism is located at one end of the feeding mechanism. The feeding mechanism includes a support plate, and a sliding groove is provided inside the support plate. A slider is slidably connected inside the sliding groove. A lead screw is threaded through the slider and connected to the lead screw. One end of the lead screw is connected to a motor. Vertical plates are provided on both sides of the support plate, and a baffle is located above the vertical plates. The curing mechanism includes a top plate and two side plates. Two side plates are symmetrically connected to the lower sides of the top plate. Multiple ultraviolet lamps are provided on the opposite side of the two side plates and below the top plate. Limiting grooves are provided at the ends of the two side plates near the baffles. A light-shielding plate is slidably connected between the two limiting grooves. Telescopic rods are provided on both sides of the light-shielding plate.

[0007] As a further feature of the above solution, the support plate is detachably connected to the base, facilitating the installation and maintenance of the support plate. A support seat is connected to the end of the slide away from the motor, and the support seat is rotatably connected to the lead screw, providing support for the lead screw. The lead screw is detachably connected to the motor, and the outer side of the motor is connected to the base via a base, facilitating the installation and maintenance of the lead screw and motor. Retractable protective covers are connected to both ends of the slider, with the ends of the two retractable protective covers, which are far apart from each other, connected to the two ends of the support plate respectively. This prevents dust or paint from adhering to the lead screw and slider, ensuring smooth rotation of the lead screw and smooth movement of the slider, reducing the workload of cleaning the lead screw and slider for the user.

[0008] As a further feature of the above solution, an electric turntable is connected above the slider, which can drive the lithium battery body to rotate so that the spraying device body can spray different surfaces of the lithium battery. An electric suction cup is connected above the electric turntable, and the lithium battery body is placed above the electric suction cup, so that the user can place the lithium battery on the electric suction cup and let it move with the slider.

[0009] As a further feature of the above solution, the lower parts of both upright plates are detachably connected to the base, and the upper parts of both upright plates are provided with protrusions. The lower end of the baffle is provided with a slot, which slides with the protrusions to facilitate the installation and maintenance of the upright plates and the baffle. This can prevent the paint from being sprayed onto the paint spraying device body on the other side during the spraying operation.

[0010] As a further feature of the above solution, a connecting plate is provided above the upright plate, and a slot is provided below the connecting plate. The upper surface of the connecting plate is lower than the lowest point of the spray nozzle in the spraying device body, which can keep the protruding plate clean and facilitate the placement of the baffle.

[0011] As a further feature of the above solution, a sealing plate is connected to the end of the top plate near the motor to prevent ultraviolet light from shining on the outside of the cavity formed by the top plate and the two side plates, thus avoiding accidental injury to the user. The lower ends of the two side plates are detachably connected to the base for easy installation and maintenance. Both ends of the ultraviolet lamp tube are connected to the top plate and the side plates through lamp holders. Connecting plates are provided at both ends of the upper part of the light shield. The connecting plates are detachably connected to the telescopic ends of the telescopic rod, allowing the light shield to slide in the limiting groove through the extension and retraction of the telescopic rod. This allows the coated lithium battery to move smoothly between the two side plates to be irradiated and cured by ultraviolet light. During the lithium battery coating process, the light shield blocks the ultraviolet light between the top plate and the two side plates, preventing ultraviolet light from shining on the spray head in the spraying device body and causing the UV coating on the spray head to solidify, thus reducing the workload of cleaning the spray head for the user. A bracket is connected to the lower end of the telescopic rod, and the lower end of the bracket is connected to the base to provide stable support for the telescopic rod.

[0012] As a further feature of the above solution, a controller is provided at the end of the base away from the motor to facilitate the control of the operation of relevant components in the device.

[0013] The present invention has the following beneficial effects during use:

[0014] The use of two retractable protective covers in the feeding mechanism can prevent dust and paint from adhering to the lead screw and slider, ensuring that the lead screw rotates smoothly and drives the slider and its upper components to move smoothly, reducing the workload of users in cleaning the lead screw and slider, and improving the efficiency of lithium battery spraying. The use of the upright plate and baffle prevents the spraying device body on one side from spraying paint onto the spraying device body on the other side during the spraying operation.

[0015] The use of a sealing plate in the curing mechanism can prevent ultraviolet light from shining on the outside of the cavity formed by the top plate and the two side plates, thus avoiding accidental injury to the user and ensuring the safety of the device. The design of two limiting grooves can restrict the movement direction of the light shielding plate, so as to block the ultraviolet light between the top plate and the two side plates during the lithium battery coating process, preventing ultraviolet light from shining on the spray head in the spraying device body and causing the UV coating on the spray head to solidify, reducing the amount of work for the user to clean the spray head. The use of two telescopic rods helps to move the light shielding plate in the limiting groove through the extension and retraction of the telescopic rods, so that the coated lithium battery can be smoothly moved between the two side plates to receive ultraviolet light irradiation and curing.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0026] An embodiment discloses a lithium battery spray coating and feeding device, including a base 1 and a feeding mechanism 2. The feeding mechanism 2 is arranged above the base 1, and spray coating device bodies 4 are arranged on both sides of the feeding mechanism 2. Both spray coating device bodies 4 are connected to the base 1. A curing mechanism 5 is arranged at one of the upper ends of the feeding mechanism 2. The feeding mechanism 2 includes a support plate 21. A groove 211 is arranged inside the support plate 21. A slider 22 is slidably connected inside the groove 211. A lead screw 23 is threaded through the slider 22 and threadedly connected to the lead screw 23. One end of the 3 is connected to a motor 231. Both sides of the support plate 21 are provided with upright plates 27. A baffle 29 is provided above the upright plates 27. The curing mechanism 5 includes a top plate 51 and two side plates 52. Two side plates 52 are symmetrically connected to the lower sides of the top plate 51. Multiple ultraviolet lamps 54 are provided on the opposite side of the two side plates 52 and below the top plate 51. A limiting groove 521 is provided at the end of the two side plates 52 near the baffle 29. A light-shielding plate 55 is slidably connected between the two limiting grooves 521. Telescopic rods 56 are provided on both sides of the light-shielding plate 55.

[0027] like Figure 1 and Figure 2 As shown, the support plate 21 is detachably connected to the base 1, facilitating the installation and maintenance of the support plate 21. A support seat 212 is connected to the end of the slide groove 211 furthest from the motor 231. The support seat 212 is rotatably connected to the lead screw 23, providing support for the lead screw 23. The lead screw 23 is detachably connected to the motor 231. The outer side of the motor 231 is connected to the base 1 via a base 232, facilitating the installation and maintenance of the lead screw 23 and the motor 231. Retractable protective covers 24 are connected to both ends of the slider 22. The ends of the two retractable protective covers 24 that are furthest from each other are connected to both ends of the support plate 21, preventing dust or paint from adhering to the lead screw 23 and slider 22, ensuring smooth rotation of the lead screw 23 and smooth movement of the slider 22, reducing the workload of cleaning the lead screw 23 and slider 22.

[0028] like Figure 1 and Figure 2As shown, an electric turntable 25 is connected above the slider 22, which can drive the lithium battery body 3 to rotate so that the spraying device body 4 can spray different surfaces of the lithium battery. An electric suction cup 26 is connected above the electric turntable 25, and the lithium battery body 3 is placed above the electric suction cup 26, so that the user can place the lithium battery on the electric suction cup 26 and let it move with the slider 22.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the lower parts of both upright plates 27 are detachably connected to the base 1, and the upper parts of both upright plates 27 are provided with protrusions 271. The lower end of the baffle 29 is provided with a slot 281. The slot 281 and the protrusions 271 are slidably engaged, which facilitates the installation and maintenance of the upright plates 27 and the baffle 29 and can prevent the paint from being sprayed onto the other side of the spraying device body 4 during the spraying operation.

[0030] like Figure 1 and Figure 3 As shown, a connecting plate 28 is provided above the upright plate 27, and a slot 281 is provided below the connecting plate 28. The upper surface of the connecting plate 28 is lower than the lowest end of the nozzle in the spraying device body 4, which can keep the protruding plate clean and facilitate the placement of the baffle 29.

[0031] like Figure 1 , Figure 5 and Figure 6 As shown, a sealing plate 53 is connected to the end of the top plate 51 near the motor 231 to prevent ultraviolet light from shining on the outside of the cavity formed by the top plate 51 and the two side plates 52 and accidentally injuring the user. The lower ends of the two side plates 52 are detachably connected to the base 1 for easy installation and maintenance. Both ends of the ultraviolet lamp tube 54 are connected to the top plate 51 and the side plates 52 through lamp holders 541. Connecting plates 551 are provided at both ends of the upper part of the light shield 55. The connecting plates 551 are detachably connected to the telescopic end of the telescopic rod 56, allowing the telescopic rod 56 to be used for telescopic communication. The telescopic movement causes the light-shielding plate 55 to slide in the limiting groove 521, so that the coated lithium battery can be smoothly moved between the two side plates 52 to be irradiated and cured by ultraviolet light. During the lithium battery coating process, the light-shielding plate 51 and the two side plates 52 are blocked from the ultraviolet light, preventing the ultraviolet light from shining on the spray head in the spraying device body 4 and causing the UV coating on the spray head to solidify, thus reducing the amount of work for the user to clean the spray head. The lower end of the telescopic rod 56 is connected to the bracket 57, and the lower end of the bracket 57 is connected to the base 1, which can provide stable support for the telescopic rod 56.

[0032] like Figure 1As shown, a controller 6 is provided at the end of the base 1 away from the motor 231 to facilitate the control of the operation of the relevant components in the device.

[0033] The lithium battery coating feeding device disclosed in this embodiment is used by placing the lithium battery to be coated on the electric suction cup 26, activating the electric suction cup 26 using the controller 6 to fix the lithium battery in place, activating the motor 231 using the controller 6 to rotate the motor 231 and move the slider 22 towards the curing mechanism 5. When the slider moves between the two coating device bodies 4, the motor 231 is turned off, the connecting plate 28 above the lower plate 27 is removed, the slot 281 below the baffle 29 is connected to the protruding plate, the baffle 29 is placed on the upper plate 27, and the coating device body 4 away from the baffle 29 is activated using the controller 6 to perform coating treatment on the lithium battery, spraying a UV insulating coating on the outside of the lithium battery. During the coating process, the electric turntable 25 is activated using the controller 6 to slowly rotate the electric suction cup 26 and the lithium battery so that the coating device body 4 can uniformly coat different positions on the outside of the lithium battery.

[0034] After spraying is completed, shut down the spraying device body 4 and the electric turntable 25. Use the controller 6 to simultaneously control the extension of the two telescopic rods 56, causing the telescopic rods 56 to slide the light shield 55 in the two limiting grooves 521. When the lower plane of the light shield 55 is higher than the upper plane of the lithium battery, shut down the telescopic rods 56 to stop them from extending. Use the controller 6 to start the motor 231, causing the motor 231 to drive the lead screw 23 to rotate inside the slider 22, pulling the slider 22 together with the electric turntable 25, electric suction cup 26 and lithium battery into the cavity formed between the top plate 51 and the two side plates 52. Shut down the motor 231. Use the controller 6 to simultaneously control the retraction of the two telescopic rods 56 to reset the light shield 55. Use the controller 6 to simultaneously start multiple ultraviolet lamps 54, causing the top plate 51, light shield 55, sealing plate 53 and the two side plates 52 to move together. An ultraviolet light environment is formed between the side plates 52, so that the lithium battery and its surface UV coating are completely exposed to ultraviolet light to cure the UV coating. After a period of time, the curing is completed. The telescopic rod 56 is extended again to lift the light shield 55 upwards until the lower plane of the light shield 55 is higher than the upper plane of the lithium battery. The telescopic rod 56 and the ultraviolet lamp 54 are closed. The controller 6 is used to start the motor 231, so that the motor 231 reverses and drives the slider 22 to slide in the slide groove 211. The slider 22 and the lithium battery are pushed together to the end of the slide groove 211 away from the motor 231. The controller 6 is used to turn off the motor 231 and the electric suction cup 26. The coated lithium battery is removed from the electric suction cup 26. A new lithium battery to be coated is placed on the electric suction cup 26. The above operation is repeated to continue the lithium battery coating operation.

[0035] The components disclosed in this utility model, including the base 1, lithium battery body 3, spraying device body 4, controller 6, support plate 21, support seat 212, slider 22, lead screw 23, motor 231, machine base 232, retractable protective cover 24, electric turntable 25, electric suction cup 26, upright plate 27, protrusion 271, top plate 51, side plate 52, ultraviolet lamp tube 54, lamp holder 541, and telescopic rod 56, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
