[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1, as Figure 1 As shown, an ink coating device for aluminum substrate production includes a machine table 1, an inner surface of the machine table 1 is provided with a loading and unloading device 5, a support frame 7 is fixedly connected to the middle of the upper end of the machine table 1, an electric telescopic rod 8 is fixedly connected to the upper end of the support frame 7, a piston rod at the output end of the electric telescopic rod 8 passes through the upper end of the support frame 7 and extends to the lower end of the support frame 7 and is fixedly connected to an ink coating device 6, a driving motor 4 that is transmission-connected to the loading and unloading device 5 is fixedly connected to the rear right end of the machine table 1 through a motor bracket, a driving device 3 that is transmission-connected to the driving motor 4 is symmetrically fixedly connected to the rear upper end of the machine table 1, and a control console 2 that is connected to the electric telescopic rod 8 and the driving motor 4 through wires is fixedly connected to the middle of the right end of the machine table 1.

[0023] It should be particularly noted that the above-mentioned console 2 is a conventional control terminal, which is used to control the extension and retraction of the electric telescopic rod 8 and the start and stop of the drive motor 4 in the control device, thereby coordinating the action frequency of the electric telescopic rod 8 and the drive motor 4 to realize automatic feeding and ink coating alternating actions. It is a commonly used control method in modern production equipment, and its internal structure and operating principle are not additionally displayed and explained in the present invention.

[0024] Further, for applying ink to the aluminum substrate, refer to Figure 2 , Figure 6 , Figure 7 and Fig. 9 The ink coating device 6 includes a mounting box 62 fixedly connected to the piston rod at the output end of the electric telescopic rod 8, a coating driving structure 61 connected to the driving device 3 is symmetrically arranged on the upper part of the inner surface of the mounting box 62, an ink supply device 63 is fixedly connected to the top wall of the inner surface of the mounting box 62, and guide structures 67 are symmetrically arranged on the left and right sides of the inner surface of the mounting box 62. The inner surfaces of the two guide structures 67 and the coating driving structure 61 are jointly provided with a scraper structure 66 that is in close contact with the bottom wall of the inner surface of the mounting box 62; The ink applying device 6 also includes a screen 65 provided on the bottom wall of the inner cavity of the installation box 62. The four corners of the lower end of the installation box 62 are fixedly connected with support blocks 64 in a rectangular distribution. The bottom wall of the inner cavity of the installation box 62 is fixedly connected with baffles 68 symmetrically around the center point of the screen 65. The two baffles 68 are both tightly attached to the scraper structure 66. A UV lamp is also installed under the paint driving structure 61 to accelerate the curing of the ink.

[0025] The above-mentioned UV lamp can accelerate the curing of ink to form a stable coating. The reaction principle is a mature technical means in the prior art and is a conventional technical means. In the present invention, its arrangement, installation method and operating principle will not be displayed and described in detail.

[0026] During the printing process of the screen 65, the ink is transferred to the aluminum substrate through the mesh holes on the screen 65 by the extrusion of the scraper structure 66, so that a uniform ink layer can be formed on the surface of the aluminum substrate to provide insulation and solder resistance; The screen 65 is woven from many tiny filamentary fibers or metal wires to form a uniform mesh structure. During the coating process, the lower end of the screen 65 is tightly fitted with the upper end of the aluminum substrate, so that in the initial state, the ink with higher viscosity can be blocked from being in the upper layer and not passing through the screen 65. Under pressure, the ink can pass through the screen 65 into the lower part and be coated on the aluminum substrate. However, the transmittance will be affected by different scraping pressures, and thus the uniformity of ink distribution will also be affected.

[0027] It should be particularly noted that the above-mentioned ink supply device 63 is a conventional material storage device for storing and providing ink. A plurality of nozzles are arranged at the lower part thereof. The peristaltic pump installed inside the device can be used to spray the ink from the nozzles and make it fall onto the bottom wall of the inner cavity of the installation box 62, thereby realizing the continuous supply of ink. The spraying frequency follows the extension frequency of the electric telescopic rod 8. The ink is sprayed when the electric telescopic rod 8 is retracted. The device is a conventional technical means in the prior art and belongs to a mature prior art. In the present invention, no additional display and explanation of its internal structure and operating principle are given.

[0028] During the operation of this embodiment, the aluminum substrate is first sent to the bottom of the installation box 62 by utilizing the cooperation between the loading and unloading equipment 5 and the driving motor 4, and the control console 2 controls the electric telescopic rod 8 to drive the installation box 62 to descend and fit with the upper side of the loading and unloading equipment 5, and the driving device 3 and the coating driving structure 61 cooperate to drive the scraper structure 66 to operate, and the scraper structure 66 cooperates with the screen 65 to make the ink evenly pass through the screen 65 and be coated on the upper layer of the aluminum substrate, and the aluminum substrate is coated for the second time by utilizing the cooperation between the coating driving structure 61, the scraper structure 66 and the guide structure 67 to ensure the uniformity of the ink application and avoid the uneven distribution of the ink caused by uneven force affecting the electrical performance of the aluminum substrate.

[0029] Embodiment 2: Based on embodiment 1, this embodiment drives the feeding belt 51 to operate intermittently by driving the driving motor 4 on the active dial 511 and synchronously utilizing the cooperation between the active dial 511 and the driven wheel 512. The aluminum substrate is intermittently driven to move forward by the cooperation between the contact block 54 provided on the active dial 511 and the material storage box 52, and gradually moves to the bottom of the coating driving structure 61. The operating frequency of the electric telescopic rod 8 is adapted through the transmission action of the driving motor 4 and the active dial 511, thereby realizing intermittent transportation of the aluminum substrate and applying ink to it during the stopping of transportation. After the coating is completed, the coated aluminum substrate is sent out by utilizing the cooperation between the pressing roller 55 and the receiving roller 56, thereby realizing automatic loading and unloading.

[0030] Specifically, to realize the loading and unloading of aluminum substrates, refer to Figure 3 and Figure 4The loading and unloading equipment 5 includes a feeding belt 51 installed on the inner surface of the machine 1. The outer surface of the feeding belt 51 is fixedly connected with a plurality of contact blocks 54 symmetrically distributed on the left and right sides in a curved distribution. The upper ends of the plurality of contact blocks 54 are rotatably connected with anti-wear rollers 541. The rear part of the upper end of the machine 1 is fixedly connected with a material storage box 52 through a connecting frame. The lower end of the material storage box 52 is symmetrically provided with connecting grooves 53 that penetrate the front and rear ends of the material storage box 52 and are connected with its inner cavity. The connecting grooves 53 are of the same width as the contact blocks 54. A discharge port of the same height and width as the aluminum substrate is provided at the front end of the material storage box 52. The rear part of the upper end of the machine 1 is rotatably connected with a pressing roller 55 through a connecting frame. The inner surface of the machine 1 is located at the tail end of the feeding belt 51 and is rotatably connected with a receiving roller 56 flush with the upper end of the feeding belt 51.

[0031] Further, in order to coordinate the action frequency of the electric telescopic rod 8 for intermittent feeding, refer to Figure 3 The loading and unloading equipment 5 also includes a driven wheel 512 which is connected to the winding shaft at the rear of the feeding belt 51. The driven wheel 512 is meshed with an active dial 511 which is rotatably connected to the right end of the machine 1. The outer surface of the active dial 511 is connected to the output end of the driving motor 4 through a belt drive.

[0032] In summary, firstly, the active dial 511 and the driven wheel 512 together constitute a grooved wheel mechanism, and its main operating rule is that every time the active dial 511 rotates one circle, the driven wheel 512 rotates a certain angle accordingly, and the displacement distance of the feeding belt 51 corresponding to the rotation angle is determined by the actual production process and the length of the aluminum substrate specification, thereby realizing intermittent feeding; When the feeding belt 51 follows the driven wheel 512, the contact block 54 enters the connecting groove 53 and drives the aluminum substrate at the bottom to slide out from the discharge port in front of the material storage box 52. At this time, the aluminum substrate on the upper side falls to the lower part under the action of gravity and is pushed out from the discharge port in sequence during the continuous operation of the feeding belt 51. The anti-wear roller 541 is provided to prevent the upper side of the contact block 54 from contacting with the upper aluminum substrate and causing scratches and damage to the upper aluminum substrate during the process of pushing out the aluminum substrate.

[0033] Furthermore, after the coating is completed and solidified, the feed belt 51 will drive the coated aluminum substrate to move backward through the contact block 54. At this time, the aluminum substrate will enter under the pressure roller 55. After the feed belt 51 turns downward, the aluminum substrate will not tilt downward due to the action of the pressure roller 55, but will be pushed to the upper side of the receiving roller 56 under the action of the contact block 54, and will be sent to the next process through an externally connected feeding device or fall into a storage box.

[0034] Embodiment 3: Based on Embodiment 2, this embodiment further utilizes the cooperation between the driving device 3 and the paint driving structure 61 to transmit the paint driving structure 61 during the descending process of the installation box 62, thereby utilizing the action of the paint driving structure 61 to drive the scraper structure 66 to slide in the guide structure 67, and through the cooperation between the guide structure 67 and the scraper structure 66, the ink on the bottom of the installation box 62 is alternately applied, so that the ink is infiltrated into the aluminum substrate below through the screen 65, and the guiding effect of the guide structure 67 is utilized to prompt the scraper structure 66 to scrape the ink for the second time, thereby ensuring that the ink is evenly distributed on the aluminum substrate, while reducing the waste of ink and improving the utilization efficiency.

[0035] Specifically, to realize the driving of the ink coating device 6, refer to Figure 5 The driving device 3 includes an L-shaped bracket 31 fixedly connected to the upper end of the machine 1, a horizontal portion of the L-shaped bracket 31 is provided with a slide groove 33 that passes through left and right, and a synchronous wheel 32 is symmetrically arranged on the inner surface of the horizontal portion of the L-shaped bracket 31. The central axis of the synchronous wheel 32 located at the rear is rotatably connected to the inner surface of the L-shaped bracket 31 and is transmission-connected to the driving motor 4. The outer surface of the synchronous wheel 32 located at the front is rotatably connected to a spring slider 34 that is slidably connected to the inner surfaces of the slide grooves 33 on both sides. The rear springs of the two spring sliders 34 are fixedly connected to the rear side walls of the inner surfaces of the adjacent slide grooves 33. The outer surfaces of the two synchronous wheels 32 are commonly wound with a synchronous belt 35. A slot 36 connected to the upper end of the L-shaped bracket 31 is provided on one side close to the ink coating device 6.

[0036] The rear synchronous wheel 32 is connected to the drive motor 4 and rotates under the action of the drive motor 4. At the same time, due to the action of the spring slider 34, the two slide grooves 33 are always at the farthest distance. At this time, the synchronous belt 35 is taut, and the synchronous belt 35 continues to run under the action of the synchronous wheel 32. When the paint driving structure 61 descends under the action of the electric telescopic rod 8, the paint driving structure 61 will enter the groove 36 and gradually press the synchronous belt 35. At this time, under the action of the tension, the spring slider 34 slides backward in the slide groove 33, and the synchronous belt 35 gradually fits on the paint driving structure 61 to transmit it.

[0037] Further, in order to drive the scraper structure 66 to slide back and forth on the inner surface of the mounting box 62 to facilitate the application of ink, refer to Figure 6 , Figure 7 and Fig. 9The paint driving structure 61 includes a second slide groove 616 opened on the upper inner surface of the installation box 62, and the inner surface of the second slide groove 616 is slidably connected with a center block 614, and the inner surface of the center block 614 is threadedly connected with a reciprocating screw 613, and the rear end of the reciprocating screw 613 passes through the inner surface of the second slide groove 616 and extends to the rear end of the installation box 62 and is transmission-connected with a bevel gear set 612 fixedly connected to the rear end of the installation box 62, and the inner surface of the input side of the bevel gear set 612 is fixedly connected with a driving wheel 611, and the central axis of the driving wheel 611 is directly above the adjacent notch 36, and one end of the center block 614 close to the scraper structure 66 is fixedly connected with a telescopic support rod 615, and the piston rod of the telescopic support rod 615 is rotatably connected to the scraper structure 66 and the lower end of the fixed part thereof is higher than the upper part of the guide structure 67.

[0038] It should be noted that the bevel gear set 612 is composed of two mutually meshing bevel gears and a mounting frame for supporting the two bevel gears, and is used to convert the power direction to achieve transmission. Its application principle is a conventional technical means in the prior art and will not be repeated in the present invention.

[0039] The driving wheel 611 gradually presses the synchronous belt 35 and rotates along with the operation of the synchronous belt 35, thereby driving the reciprocating screw 613 to rotate through the bevel gear set 612. During the rotation of the reciprocating screw 613, the center block 614 slides in the second slide groove 616. At this time, the center block 614 pulls the scraper structure 66 to slide in the guide structure 67 through the telescopic support rod 615, thereby scraping the ink on the upper side of the screen 65 and promoting the ink to penetrate the screen 65 and penetrate into the upper layer of the aluminum substrate.

[0040] The surface of the reciprocating screw 613 is a bidirectional thread, and the threaded connection between it and the center block 614 is a tongue-shaped slide. During the continuous rotation of the reciprocating screw 613, the slide slides in the track on the surface of the reciprocating screw 613 until it reaches the opposite side and enters the reverse track through a smooth arc groove, and moves back through the reverse track, thereby realizing reciprocating motion. This operating mode has been widely used in the prior art and is a mature technical means. Its specific operating mode and principle will not be displayed or elaborated in the present invention.

[0041] Further, in order to guide the running track and state of the scraper structure 66, refer to Figure 8 The guide structure 67 includes a horizontal groove 1 671 provided at the lower part of the inner surface of the installation box 62, a magnetic block 672 is fixedly connected to the inner surface of the horizontal groove 1 671 symmetrically in the front and back, a horizontal groove 2 673 is provided at the upper part of the inner surface of the installation box 62, and triangular grooves 674 are provided on the left and right sides of the inner surface of the horizontal groove 2 673, and the connection between the two triangular grooves 674 and the horizontal groove 2 673 is unidirectionally connected with a baffle 675 tightly attached to the bottom wall of the inner surface of the horizontal groove 2 673, and the baffle 675 connects the horizontal groove 2 673 with the inclined surface of the triangular groove 674 in the initial state.

[0042] Further, to achieve uniform scraping of the ink, refer to Figure 8 , Fig. 9 and Fig.10 The scraper structure 66 includes a connecting block 662 and a sliding block 663. A partition is provided in the middle of the inner surface of the sliding block 663. A plurality of compression springs 668 are linearly distributed and fixedly connected at the lower end of the connecting block 662. The ends of the plurality of compression springs 668 away from the connecting block 662 are commonly fixedly connected to a sliding plate 667. The end of the sliding plate 667 close to the connecting block 662 is fixedly connected to a plurality of limit rods slidably connected to the inner surface of the connecting block 662. The outer surface of the sliding plate 667 is slidably connected to the upper side of the inner surface of the sliding block 663.

The lower ends of the plurality of compression springs 666 are commonly fixedly connected to a silicone scraper 664 slidably connected to the lower inner surface of the ink supply device 63. The left and right ends of the connecting block 662 are fixedly connected and are slidably connected to the upper rollers 661 on the inner surfaces of the horizontal groove 2 673 and the triangular groove 674. The outer surfaces of the central axes of the two upper rollers 661 are rotatably connected to the inner surfaces of the piston rods at the output ends of the adjacent telescopic support rods 615. The left and right ends of the sliding block 663 are slidably connected to the lower rollers 665 on the inner surfaces of the adjacent horizontal groove 1 671. The lower rollers 665 are made of metal and can be adsorbed by the magnetic block 672.

[0043] In summary, when the telescopic support rod 615 moves forward, it will drive the upper roller 661 to slide in the horizontal groove 673. In this process, due to the adsorption of the magnetic block 672, the lower roller 665 is tightly fitted with the magnetic block 672. The movement of the upper roller 661 will cause the connecting block 662 and the sliding plate 667 to slide downward in the sliding block 663, and gradually press the compression spring 1 666 to shrink it, until the connecting block 662 changes from tilting backward to tilting forward. At this time, the ink is within the angle between the silicone scraper 664 and the screen 65, and the magnetic block 672 and the lower roller 665 are still adsorbed together. The upper roller 661 continues to follow the movement of the telescopic support rod 615, and the sliding plate 667 is pulled by the connecting block 662 to slide upward until it reaches the top. At this time, the connecting block 662 pulls the sliding block 663 through the compression spring 2 668 and the sliding plate 667. The suction force of the magnetic block 672 is not enough to resist the pulling force provided by the compression spring 2 668. At this time, the lower roller 665 is separated from the magnetic block 672. The silicone scraper 664 is kept tilted forward and scrapes the ink to move on the screen 65 to smear the aluminum substrate. Before the lower roller 665 reaches the front of the horizontal groove 671, the upper roller 661 moves upward along the baffle 675 and the triangular groove 674. Since the sliding block 663 and the lower roller 665 are sliding, the lower roller 665 is restricted in the horizontal groove 671 by the magnetic block 672 and the horizontal groove 671. However, the sliding block 663 and the silicone scraper 664 installed therein are lifted upward by the connecting block 662, and the silicone scraper 664 passes over the ink to reach the front of the ink until the upper roller 661 falls from the vertical part of the silicone scraper 664. At this time, the lower roller 665 is adsorbed by the magnetic block 672 on the front side, and the scraping structure 66 as a whole can be regarded as tilting forward. Similarly, when the scraper structure 66 moves backward, after the upper roller 661 returns to the intersection of the horizontal and vertical parts of the triangular groove 674 at the rear, the silicone scraper 664 is at the rear of the ink. Through the reciprocating movement of the scraper structure 66, the ink is scraped twice, thereby promoting the ink to penetrate downward through the mesh of the screen 65 and ensuring the uniformity of the coating on the aluminum substrate.
