Detailed implementation manners

[0018] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the following further details the present invention in combination with specific embodiments.

[0019] Embodiment 1:

[0020] As Figure 1 , Figure 2 and Figure 3As shown in the figure, a rapid curing light solidifying machine for screen printing ink includes: an ultraviolet light emitter 11, and a fixing plate 1 fixedly installed on one side of the ultraviolet light emitter 11 by bolts; it also includes: a support plate 2 arranged at both ends of the fixing plate 1, a servo motor 21 is fixedly installed on one side of the support plate 2 by bolts, the power output end of the servo motor 21 passes through the support plate 2 and is connected to the fixing plate 1, and the servo motor 21 drives the fixing plate 1 to adjust the swing angle of the ultraviolet light emitter 11, so as to be able to adjust the irradiation range of the ultraviolet light emitter 11, so that each battery case sprayed with screen printing ink and photosensitizer during the conveying process can obtain the light solidifying effect of a fan-shaped irradiation path under the ultraviolet light emitter 11. Since the two servo motors 21 are arranged oppositely, when driving, the two servo motors 21 rotate synchronously and in opposite directions, so that the fixing plate 1 can be deflected; a support plate 3 is arranged below the support plate 2, an electric push rod 31 is fixedly installed on one side inside the support plate 3 by bolts, the output end of the electric push rod 31 passes through the support plate 3 and is fixedly connected to the support plate 2 by bolts. Through the driving and adjusting action of the electric push rod 31, the position height of the support plate 2 can be adjusted, and then the light solidifying process can be carried out on the battery cases sprayed with screen printing ink and photosensitizer at different heights. A vertically oriented slot 32 is opened on one side above the support plate 3, a plug rod 33 is movably inserted into the slot 32, the top of the plug rod 33 is fixedly connected to the support plate 2 by bolts. Through the positioning action of the plug rod 33, the stability of the support plate 2 during movement can be further limited. The plug rod 33 is arranged in parallel with the electric push rod 31; a flexible tube 4 is fixedly installed on the opposite sides of the periphery of the support plate 3 by bolts, one end of the flexible tube 4 is fixedly installed with a mounting block 41 by bolts, and a pair of photoelectric switches 42 are fixedly installed on one side of the mounting block 41. The pair of photoelectric switches 42 are used to detect the transmission position of the battery cases sprayed with screen printing ink and photosensitizer to control the start and stop of the ultraviolet light emitter 11. By providing the flexible tube 4, it is convenient for users to adjust the opposite position of the pair of photoelectric switches 42, so as to be able to make detection position change adjustments according to the outer shape of the battery cases sprayed with screen printing ink and photosensitizer, improving the accuracy of detecting the position of the motor case; a clamping assembly is arranged at the bottom of the support plate 3, and the clamping assembly is used to fixedly install the support plate 3 to the conveyor belt of the battery cases sprayed with screen printing ink and photosensitizer through bolts, so that the battery cases sprayed with screen printing ink and photosensitizer during the conveying process are solidified.

[0021] Among them, the support plate 3 is installed on both sides of the conveyor belt for transporting the battery case sprayed with screen printing ink and photosensitizer through the clamping assembly. According to the height of the transported battery case, the position height of the two support plates 2 is adjusted by the electric push rod 31, so that the battery case can be transported under the ultraviolet light emitter 11 installed on the fixing plate 1. At the same time, the ultraviolet light is irradiated by means of the ultraviolet light emitter 11, so that the screen printing ink sprayed is cured on the battery case by means of the photosensitizer, thereby effectively improving the curing efficiency. The opposed switches 42 are fixed on both sides of the support plate 3 through the flexible tubes 4, so that the opposed position and angle of the opposed switches 42 can be adjusted according to the shape of the battery case during the transportation process. With the driving effect of the servo motor 21, the irradiation position of the ultraviolet light emitter 11 can be synchronously adjusted, thereby effectively improving the effect of flexibly curing the battery cases sprayed with screen printing ink in different shapes and effectively improving the curing efficiency.

[0022] Embodiment 2:

[0023] The difference from the previous embodiment is that threaded sets 23 are fixedly installed near both ends above the fixing plate 1 through bolts. A lead screw 22 is threadedly inserted in the middle of the threaded set 23. The power output end of the servo motor 21 passes through the support plate 2 and is fixedly connected to the end of the lead screw 22 through a bolt. Positioning nuts 24 are threadedly sleeved on the periphery of the lead screw 22 on both sides of the threaded set 23. The positioning nuts 24 are used to limit the position of the threaded set 23 on the lead screw 22. Two limit rods 25 are fixedly installed on the side of the support plate 2 close to the fixing plate 1 through bolts. The two limit rods 25 are symmetrically arranged with the central axis of the lead screw 22. The limit rods 25 are used to limit the swing amplitude of the fixing plate 1.

[0024] Among them, by adjusting the position of the threaded set 23 on the lead screw 22 and with the help of the positioning nuts 24 on both sides of the threaded set 23, the position between the fixing plate 1 and the support plate 2 can be limited, so that the ultraviolet light emitter 11 can irradiate the battery cases sprayed with screen printing ink on the conveyor belts at different positions, further improving the curing effect of the battery cases placed at different positions on the conveyor belt. By providing two symmetrically arranged limit rods 25 on the support plate 2, the irradiation range of the ultraviolet light emitter 11 can be limited, thereby preventing the risk of irradiating the staff and improving the safety during the curing process.

[0025] Embodiment 3:

[0026] The difference from the second embodiment is that the clamping assembly includes: a chassis 5, which is fixedly installed at both ends of the bottom of the support plate 3 by bolts. A threaded sleeve 51 is threadedly inserted in the middle of the chassis 5. One end of the threaded sleeve 51 passes through the chassis 5 and is fixedly connected to a clamping disc 52 by bolts; a screw rod 53 is threadedly inserted in the middle of the threaded sleeve 51. One end of the screw rod 53 passes through the clamping disc 52 and is rotatably connected to a pressure disc 54 through a bearing. An elastic rubber ring 55 is sleeved on the outer periphery of the screw rod 53 between the pressure disc 54 and the clamping disc 52. By adjusting the distance between the pressure disc 54 and the clamping disc 52, the expansion amount of the elastic rubber ring 55 is adjusted to change the outer diameter of the elastic rubber ring 55; a receiving groove is formed on one side of the clamping disc 52 close to the pressure disc 54, and the elastic rubber ring 55 is arranged in the receiving groove. The distance between the pressure disc 54 and the clamping disc 52 is adjusted to adjust the extension amount of the elastic rubber ring 55; anti-slip patterns are formed on the outer periphery of the pressure disc 54 and the outer periphery of the clamping disc 52.

[0027] Among them, the chassis 5 is placed on both sides of the conveyor belt. The position between the clamping discs 52 is adjusted by rotating the threaded sleeve 51, so that the two support plates 3 are installed and fixed on both sides of the conveyor belt by means of the clamping force, and the ultraviolet light emitter 11 projects towards the battery case on the conveyor belt. By rotating the screw rod 53, the distance between the pressure disc 54 and the clamping disc 52 is adjusted, so that when the elastic rubber ring 55 between the two is embedded in the gap on both sides of the conveyor belt, the firmness of the clamping disc 52 and the pressure disc 54 on both sides of the conveyor belt can be further improved, and the installation stability effect is further improved.

[0028] Working principle: When in use, the support plate 3 is installed on both sides of the conveyor belt for transporting battery cases sprayed with screen printing ink and photosensitizer through the clamping assembly. According to the height of the transported battery cases, the position height of the two support plates 2 is adjusted by the electric push rod 31, so that the battery cases can be transported under the ultraviolet light emitter 11 installed on the fixed plate 1. At the same time, ultraviolet light irradiation is carried out by means of the ultraviolet light emitter 11, so that the screen printing ink sprayed is cured on the battery cases by means of the photosensitizer. The opposed switches 42 are fixed on both sides of the support plate 3 through the flexible tubes 4, so that the opposed position and angle of the opposed switches 42 can be adjusted according to the form of the battery cases during the transportation process. When the form of the battery case is larger, the opposed switches 42 on the opposite sides are opposed and irradiated on the periphery of the battery case through the flexible tubes 4 to detect the transportation position of the battery case. By obtaining the detection position and transportation time of the battery case, the irradiation angle of the ultraviolet light emitter 11 is synchronously adjusted, so that the ultraviolet light emitter 11 can always irradiate towards the periphery of the battery case during the transportation process of the battery case between the two groups of opposed switches 42. Similarly, when the form of the battery case is smaller and the transportation position of the battery case is offset, the transportation state of the battery case is detected by the two groups of opposed switches 42 to synchronously adjust the irradiation angle of the ultraviolet light emitter 11 on the battery case, so that the battery case can be in the irradiation state when being transported between the two groups of opposed switches 42. With the driving effect of the servo motor 21, the irradiation position of the ultraviolet light emitter 11 can be synchronously adjusted, thereby effectively improving the effect of flexibly curing battery cases sprayed with screen printing ink in different forms, effectively improving the curing efficiency. The chassis 5 is placed on both sides of the conveyor belt, and the position between the clamping disks 52 is adjusted by rotating the threaded sleeve 51, so that the two support plates 3 are installed and fixed on both sides of the conveyor belt by means of the clamping force, and the ultraviolet light emitter 11 projects towards the battery cases on the conveyor belt. By rotating the screw rod 53 to adjust the distance between the pressing disk 54 and the clamping disk 52, when the elastic rubber ring 55 between the two is embedded in the gaps on both sides of the conveyor belt, the firmness of the clamping disk 52 and the pressing disk 54 on both sides of the conveyor belt can be further improved, and the installation stability effect is further improved.
