Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter assembly technology, and in particular to an automatic filter assembly fixture. Background Technology
[0002] The filter assembly fixture solves efficiency bottlenecks (e.g., 50% faster pump body filter assembly) and quality risks (e.g., glue-free carbon cloth filter assembly) in filter assembly through three core technologies: precision positioning (multi-axis guidance), synchronous pressing (cylinder linkage), and flexible clamping (rubber / magnetic attraction). In the future, with the increasing demand for flexible manufacturing, modular quick-change design and IoT pressure monitoring (real-time feedback of pressing force) will become key upgrade priorities. When selecting a fixture, it is necessary to match the filter material characteristics (plastic / metal / composite layer) with the production line cycle time requirements, prioritizing the fixture's compatibility, expandability, and ease of maintenance.
[0003] However, existing devices require each filter to be placed individually during automatic filter assembly, which necessitates continuous filter placement by the user. Furthermore, the device must be stopped during filter placement, increasing the workload for workers and affecting the continuity of operation. Utility Model Content

[0007] The ejection assembly includes a stepper servo motor and a rotating rod. The output end of the stepper servo motor is fixedly connected to a pulley A, and a pulley B is sleeved on the surface of the rotating rod. The pulley A and pulley B are connected by a synchronous belt drive. A rotating plate is fixedly connected to the top of the rotating rod, and a cylinder three abuts against the bottom of the rotating plate. A photoelectric switch is installed below the rotating plate, and the bottom of the photoelectric switch is installed on the top of the operating table.
[0008] As a further improvement to the above solution, a connecting frame is fitted onto the surface of the stepper servo motor and the surface of the rotating rod. The top of the connecting frame is fixedly connected to the top of the inner wall of the operating table, ensuring the normal operation of the stepper servo motor and the rotating rod.
[0009] As a further improvement to the above solution, an ejector plate is fixedly connected to the top of the cylinder three, and the surface of the cylinder three is installed on the bottom of the inner wall of the operating table to facilitate the ejection operation of the cylinder three.
[0010] As a further improvement to the above solution, a touch screen is installed on the surface of the control panel, and buttons are also installed on the surface of the control panel to facilitate the adjustment and setting of the device.
[0011] As a further improvement to the above solution, the surface of the rotating plate is provided with equally spaced slots for placing the filter screen.
[0012] As a further improvement to the above solution, the top of the operating table is provided with an opening for the three output ends of the cylinder to pass through, ensuring the normal operation of the three output ends of the cylinder.
[0013] As a further improvement to the above solution, the top of the operating table is provided with a mounting groove, and a rotating bearing is installed inside the mounting groove. The surface of the rotating rod is installed inside the rotating bearing, which ensures the normal operation of the rotating rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, through the setting of a drive component, allows the user to place the product inside the placement slot during use. Cylinder three is activated to lift the product from the slot, followed by activation of cylinder one, which moves the filter vacuum nozzle downwards to contact the product surface. The filter vacuum nozzle then holds the product in place. Cylinder two is then activated, causing cylinder one to move to the right, aligning the product with the jig positioning mold. Cylinder one is then activated again to move the product downwards, allowing it to fall onto the jig positioning mold via the filter vacuum nozzle. Finally, the filter vacuum nozzle is reset, and the stepper servo motor is activated. Under the action of pulleys A and B and the synchronous belt, the rotating plate rotates 90 degrees, switching to another product in the placement slot. This process is repeated, enabling the device to automatically assemble the filter. Attached Figure Description
