Description

Technical Field

[0001] This utility model relates to the field of automated printing equipment technology, and in particular to a fully automatic side screen printing machine for lead-acid batteries. Background Technology

[0002] Lead-acid batteries, as a traditional energy storage device, are widely used in automotive starting, power system backup power, and industrial equipment. In the production process of lead-acid batteries, labeling and printing are an indispensable step, used to indicate important information such as the battery model, specifications, production date, and voltage. Accurate and clear labeling not only helps in product identification and tracking but also plays a crucial role in ensuring user safety and compliant operation. Currently, to reduce errors caused by manual printing and to meet the high standards of modern industrial production, automatic side screen printing machines have emerged. These machines can complete precise screen printing operations on the sides of lead-acid batteries with minimal human intervention, thereby significantly improving production efficiency and printing quality.

[0003] Patent CN212332101U discloses a fully electric screen printing machine. This device utilizes an X-axis motor, a Y-axis motor, and a printing depth motor for drive. The required printing action is achieved through the cooperation of an X-axis moving component, a Y-axis lifting component, and a printing depth component. Compared to the traditional cylinder-driven method, this design avoids the need for an air compressor, simplifying the system structure. In addition, the working status of the X-axis motor, Y-axis motor, and printing depth motor can be precisely controlled by a PLC controller, making operation simpler and more efficient.

[0009] As a further preferred embodiment, the horizontal movement assembly includes an electric slide rail, a slider, a third mounting plate, and a second mounting base. The second mounting plate is fixedly connected to symmetrically distributed electric slide rails, and sliders are mounted on the electric slide rails. The sliders are all fixedly connected to the third mounting plate, and the third mounting plate is fixedly connected to the second mounting base.

[0010] As a further preferred embodiment, the scraper fixing assembly includes a telescopic cylinder, a support rod, a scraper mounting bracket, and a connecting block. The second mounting base is equipped with symmetrically distributed telescopic cylinders, and the second mounting base is slidably provided with symmetrically distributed support rods.

[0021] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0022] Example 1: Please refer to Figure 1 and Figure 2A fully automatic side screen printing machine for lead-acid batteries includes a base 1, a housing 2, a mounting platform 3, a screen printing assembly, a height adjustment assembly, a horizontal movement assembly, a squeegee fixing assembly, a human-machine interface platform 4, a first servo motor 5, a conveyor belt 6, a lead-acid battery 601, a baffle 7, a blocking cylinder 8, and a clamping cylinder 9. The housing 2 has bases 1 at each of its four bottom corners, and the mounting platform 3 is located on top of the bases 1. The screen printing assembly, height adjustment assembly, horizontal movement assembly, and squeegee fixing assembly are located on the rear side of the mounting platform 3. The human-machine interface platform 4 is located on the front side of the mounting platform 3, used for operating and controlling the entire equipment's operating parameters, status monitoring, and fault indication functions. The housing 2 has a base 1 at each of its four bottom corners, and the mounting platform 3 is located on top of the bases 1. The mounting platform 3 has the screen printing assembly, height adjustment assembly, horizontal movement assembly, and squeegee fixing assembly located on its rear side. The mounting platform 4 is located on its front side, used for operating and controlling the entire equipment's operating parameters, status monitoring, and fault indication functions. A first servo motor 5 is installed on the surface of the mounting platform 3, and a conveyor belt 6 is installed on the top of the mounting platform 3. The conveyor belt 6 is driven by the first servo motor 5 to automatically transport the lead-acid battery 601 from left to right. Two baffles 7 are symmetrically distributed on the top of the conveyor belt 6 to limit the lead-acid battery 601 in the front-back direction and prevent it from deviating during transportation. A blocking cylinder 8 is installed on one side of the baffle 7 to block subsequent lead-acid batteries 601 from entering the processing area during the positioning process, ensuring that a single battery is in an effective working position. A clamping cylinder 9 is installed on the other side of the baffle 7 to clamp the lead-acid battery 601 to be processed, ensuring its accurate positioning.

[0023] When using this device, the flipped lead-acid battery 601 is first placed at the starting end of the conveyor belt 6. After starting the equipment, the first servo motor 5 drives the conveyor belt 6 to rotate, conveying the lead-acid battery 601 from left to right at a set speed. During the conveying process, the baffles 7 on both the front and rear sides guide and limit the lead-acid battery 601 to prevent it from tilting or deviating during movement. When the lead-acid battery 601 reaches the designated printing station, the blocking cylinder 8 is activated, and its movable rod extends to block the subsequent battery to prevent it from interfering with the current processing. Subsequently, the clamping cylinder 9 is activated, and its movable rod pushes the clamping baffle 7 inward to move the battery currently located at the printing station. The lead-acid battery 601 is clamped to ensure that it will not shift during the printing process, thereby improving printing accuracy. After the lead-acid battery 601 is positioned and clamped, the screen assembly is precisely adjusted to the appropriate printing height by the height adjustment component. At the same time, the horizontal moving component drives the squeegee fixing component to move laterally along the guide rail, so that the squeegee applies pressure and slides evenly on the screen to complete the screen printing operation on the side of the lead-acid battery 601. The entire screen printing process can be operated through the human-machine interaction platform 4 to set parameters, monitor the operating status, and view alarm information, so as to realize intelligent management and efficient operation of the equipment, improve production efficiency and printing accuracy, and reduce manual intervention.

Figure 3 and Figure 4 The screen assembly includes a first mounting base 10, a mounting bracket 11, a fixed screen plate 12, a screen printing screen plate 13, an anti-slip screw wheel 1401, a bolt 14, and a clamping block 15. The two first mounting bases 10 are arranged symmetrically from left to right. Each first mounting base 10 is provided with a mounting bracket 11. The fixed screen plate 12 is fixedly connected to the mounting bracket 11. The screen printing screen plate 13 is sandwiched between the two fixed screen plates 12. The fixed screen plate 12 has two threaded holes symmetrically distributed front to back. The bolt 14 passes through the threaded hole and is threadedly connected to it. The top of the bolt 14 is provided with an anti-slip screw wheel 1401, and the bottom of the bolt 14 is provided with a clamping block 15 for clamping the screen printing screen plate 13 to ensure the stability of the screen plate during the printing process.

[0025] Please see Figure 5 The height adjustment assembly includes a first mounting plate 16, a second servo motor 17, a reciprocating screw 18, a guide rod 19, a reciprocating seat 20, and a second mounting plate 21. Two guide rods 19 are symmetrically distributed on the left and right sides and fixed to the top rear side of the mounting platform 3. The top ends of the two guide rods 19 are jointly fixed to the first mounting plate 16. The second servo motor 17 is mounted on the top of the first mounting plate 16. The output shaft of the second servo motor 17 is connected to the reciprocating screw 18. The reciprocating seat 20 is threaded on the reciprocating screw 18. The two sides of the reciprocating seat 20 are slidably connected to the two guide rods 19 to form a guiding fit. The second mounting plate 21 is fixedly connected to the reciprocating seat 20 and is fixedly connected to the first mounting seat 10 to drive the wire mesh assembly to achieve vertical lifting and lowering adjustment.

[0026] Please see Figure 3 and Figure 5 The horizontal moving component includes an electric slide rail 22, a slider 23, a third mounting plate 24, and a second mounting base 25. Two electric slide rails 22 are fixedly connected to the second mounting plate 21, which are symmetrically distributed vertically. A slider 23 is installed on each of the electric slide rails 22. The two sliders 23 are fixedly connected to the third mounting plate 24. The second mounting base 25 is fixedly connected to the third mounting plate 24, which is used to drive the scraper fixing component to move left and right in the horizontal direction.

[0027] Please see Figure 5 and Figure 6The scraper fixing assembly includes a telescopic cylinder 26, a support rod 27, a scraper mounting bracket 28, and a connecting block 29. Two telescopic cylinders 26 are symmetrically distributed on the second mounting base 25. Two support rods 27 are slidably distributed on the second mounting base 25. The support rods 27 are fixedly connected to the movable rods of the telescopic cylinders 26. A connecting block 29 is fixedly connected to the bottom end of the support rods 27. The scraper mounting bracket 28 is detachably installed on the bottom of the connecting block 29. The scraper mounting bracket 28 has a slot, which can realize the quick installation and replacement of the screen printing scraper.

[0028] Please see Figure 2 and Figure 3 It also includes a protective component installed on the mounting platform 3. The protective component includes a protective frame 30, a first dustproof plate 31, and a second dustproof plate 32. The protective frame 30 is fixed to the rear side of the mounting platform 3. The protective frame 30 is completely covered around the height adjustment component and is used to physically isolate and protect key transmission components such as servo motors, reciprocating screws 18, and guide rods from dust, thereby improving the safety and stability of equipment operation. The first dustproof plate 31 is fixed to the front side of the protective frame 30 to seal the protective frame 30. The second dustproof plate 32 is provided on the front side of the second mounting plate 21. The second dustproof plate 32 is located in front of the movement path of the electric slide rail 22 to prevent ink splashes or foreign objects from falling into the electric slide rail 22.

[0029] Before use, the operator selects a suitable screen printing stencil 13 according to the battery model to be printed and places it between two fixed stencils 12. Then, by rotating the anti-slip screw wheel 1401, the bolt 14 is pressed down, causing the clamping block 15 to clamp the screen printing stencil 13 to ensure stability during the printing process. At the same time, the squeegee is also installed on the squeegee mounting bracket 28, ready for printing. When the equipment starts running, the second servo motor 17 starts, driving the reciprocating lead screw 18 to rotate, causing the reciprocating seat 20 to slide up and down along the guide rod 19. The reciprocating seat 20 drives the first mounting seat 10, the screen assembly, the horizontal moving assembly, and the squeegee fixing assembly to move up and down as a whole through the second mounting plate 21, thereby achieving a high degree of matching between the screen printing stencil 13 and the surface of the lead-acid battery 601. This function can be used for lead-acid batteries 601 of different sizes. Automatic or manual adjustment ensures printing accuracy and consistency. When the screen printing plate 13 is adjusted to the appropriate position, the telescopic cylinder 26 is activated, pushing the support rod 27 downward, causing the squeegee mounting bracket 28 and the squeegee to press against the surface of the screen printing plate 13. At this time, the electric slide rail 22 drives the slider 23 to move left and right, causing the third mounting plate 24 and its second mounting seat 25 to move synchronously, thereby causing the squeegee fixing assembly to move laterally. Driven by the electric slide rail 22, the squeegee slides uniformly across the screen printing plate 13 from left to right, transferring the ink evenly to the side of the lead-acid battery 601, completing one complete printing action. After printing is completed, the telescopic cylinder 26 retracts, causing the squeegee to lift up to avoid smudging the printed pattern. At the same time, the reciprocating seat 20 drives the entire printing mechanism to move upward, detaching from the surface of the lead-acid battery 601, preparing for the next cycle.

[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
