Description

Technical Field

[0001] This invention relates to an automatic filter screen assembly device, specifically to an automatic filter screen assembly machine. Background Technology

[0002] A filter is a device for filtering impurities from a medium. It includes a filter screen and a filter plate. The filter screen is fixed to the filter plate. Filter plates are classified by shape, such as rectangular, circular, annular, and square. The shape of the filter plate is determined by its working part; for example, diesel filters in large equipment diesel engines typically use rectangular filter plates. The filter plate is machined from a single piece of metal. It has medium passage holes and closed-loop grooves on its side walls. After the filter screen completely covers one side of the filter plate, the perimeter is pressed into the grooves by pressure strips to fix the screen in place. Currently, the assembly of filter screens and filter plates is generally done manually, which has the following technical drawbacks: 1. Manual assembly is inefficient, time-consuming, and labor-intensive. 2. The pressure strips do not press evenly into the grooves, resulting in an unstable filter screen and potential damage. Summary of the Invention

[0003] To address the problems of low assembly efficiency, loose filter screens, and easy filter screen damage in existing filter screen assembly, this invention provides an automatic filter screen assembly machine that replaces manual filter screen assembly. It has high assembly efficiency, uniform pressure from the pressure bar, and ensures a secure filter screen without causing damage.

[0004] The technical solution of the present invention is: an automatic filter assembly machine, comprising a frame, on which a linear module, a linear pushing device, and a divider are provided. The linear pushing device is connected to a slider in the linear module, and the linear module can drive the linear pushing device to move linearly along the direction of a vertical push rod. A pressure head is connected to the push rod of the linear pushing device, and the pressure head is adapted to a groove on the side wall of the filter plate. A support plate is connected to the output shaft of the divider, and a support column and a lifting cylinder are fixed on the support plate. A positioning plate is fixed at the upper end of the support column, and the positioning plate is used to support and position the filter plate. A protective frame that can slide up and down is provided on the support column, and a through hole is provided on the protective frame. The outer contour of the through hole is adapted to the filter plate, and the lifting cylinder can drive the protective frame to rise and fall.

[0005] The linear pusher is an electric push rod.

[0006] The dividing angle of the divider is 90 degrees.

[0007] The support plate is rectangular, and there are four support columns located at the four corners of the support plate.

[0008] A guide frame is fixed on the support column, and a guide sleeve is provided on the guide frame. A guide rod is fixed at the lower end of the protective frame. The guide rod is located inside the guide sleeve and can slide along the guide sleeve.

Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings.

[0017] like Figures 1-3As shown, an automatic filter assembly machine includes a frame 1. The frame 1 is equipped with a linear module 2, a linear pushing device 3, and a divider 4. The linear pushing device 3 is connected to a slider in the linear module 2. The linear module 2 can drive the linear pushing device 3 to move linearly along a direction perpendicular to the push rod. A pressure head 5 is connected to the push rod of the linear pushing device 3. The pressure head 5 is adapted to a groove 7 on the side wall of the filter plate 6. A support plate 8 is connected to the output shaft of the divider 4. A support column 9 and a lifting cylinder 10 are fixed on the support plate 8. A positioning plate 17 is fixed to the upper end of the support column 9. The positioning plate 17 is used to support and position the filter plate 6. A sliding guard frame 11 is provided on the support column 9. The guard frame 11 has a through hole 12, the outer contour of which is adapted to the filter plate 6. The lifting cylinder 10 can drive the guard frame 11 to rise and fall. This embodiment uses a rectangular filter plate 6 as an example for illustration. Due to the adoption of the above technical solution, when assembling the filter screen, the protective frame 11 is in a raised state. First, the filter screen plate 6 is placed on the positioning plate 17. The outer contour of the positioning plate 17 is consistent with the outer contour of the filter screen plate 6. After being positioned by the positioning plate 17, the filter screen plate 6 is aligned with the periphery of the positioning plate 17. The pre-cut filter screen is placed on top of the filter screen plate 6. The lifting cylinder 10 is activated, causing the protective frame 11 to descend until the upper surface of the protective frame 11 is flush with the lower inner wall of the groove 7 on the side wall of the filter screen plate 6. At this time, the protective frame 11 stops, and the groove 7 is located above the protective frame 11. The pressure strip is aligned with the groove 7, and the linear pushing device 3 works and squeezes the pressure strip through the pressure head 5. Within the groove 7, the PLC controls the coordinated operation of the linear module 2, the linear pushing device 3, and the divider 4. The linear module 2 drives the linear pushing device 3 to move along the direction of the groove 7 on the filter plate 6. The pressure head 5 gradually squeezes the pressure strip into the groove 7. When it reaches the inflection point, the pressure head 5 retracts. The divider 4 can rotate intermittently at 90-degree intervals according to a certain working rhythm. After one side of the filter plate 6 has been pressed by the pressure strip, the pressure head 5 retracts, the divider 4 drives the filter plate 6 to rotate 90 degrees, and the pressure head 5 extends again to continue pressing the pressure strip into the groove 7 of the next side of the filter plate 6. This process continues until the pressure strip is completely closed in the groove 7 of the filter plate 6, and the filter assembly is completed. The filter plate 6 with the installed filter is removed, and the assembly of the filter on the next filter plate 6 is performed. This invention replaces manual operation for assembling filter screens, resulting in high assembly efficiency, uniform pressure of the pressure strip, and a secure filter screen that will not be damaged.

[0018] The linear pusher 3 is an electric push rod. Using an electric push rod facilitates automated control.

[0019] The dividing angle of the divider 4 is 90 degrees. This embodiment is designed only for quadrilateral workpieces, and the dividing angle of the divider 4 can be determined according to the specific dividing angle required by the workpiece.

[0020] The support plate 8 is rectangular, and there are four support columns 9 located at the four corners of the support plate 8. The structure is simple and easy to process and assemble.

[0021] A guide frame 13 is fixed on the support column 9, and a guide sleeve 14 is provided on the guide frame 13. A guide rod 15 is fixed to the lower end of the protective frame 11. The guide rod 15 is located inside the guide sleeve 14 and can slide along the guide sleeve 14. The guide rod 15 and the guide sleeve 14 play a guiding role, ensuring that when the protective frame 11 moves up and down, the through hole 12 on the protective frame 11 can correspond to the filter screen plate 6 and fit snugly around the filter screen plate 6 to press down the filter screen.

[0022] A surrounding plate 16 is provided below the protective frame 11. The surrounding plate 16 serves a protective function to prevent the filter screen from interfering with the lifting cylinder 10.

[0023] The positioning plate 17 is provided with a central positioning pin 18 and two side positioning pins 19. The filter plate 6 is positioned by three-point axial hole positioning through the central positioning pin 18 and the two side positioning pins 19, which ensures accurate positioning and alignment of the filter plate 6 with the periphery of the positioning plate 17.
