Description
Technical Field
[0001] This invention relates to the field of transmission filter processing technology, and in particular to an automatic assembly device for transmission filters. Background Technology
[0002] Hydraulic oil often contains particulate impurities, which can cause wear on the relatively moving surfaces of hydraulic components, valve jamming, and blockage of throttling orifices, greatly reducing the reliability of the system. Installing a filter element in the system is a necessary means to ensure the normal operation of the hydraulic system.
[0003] Currently, transmission filter elements typically involve placing filter paper on top of a plate and then pressing the plate together with a cover plate. On current transmission filter element assembly lines, manual labor is heavily involved. For example, before the cover plate is pressed in by the pressing equipment, to prevent the plastic cover plate from being damaged, manual labor is required to use a hammer to tap the side of the plate to hold the top surface of the cover plate in place for pre-assembly. Then, the plate is placed on the pressing platform for pressing. This step is inefficient and consumes a lot of manpower. Summary of the Invention

[0012] Furthermore, the auxiliary clamping assembly also includes a fixed plate, a movable plate, a connecting rod, an elastic element, and a lifting cylinder fixedly connected to the worktable. The connecting rod passes through the fixed plate, with one end fixedly connected to the movable plate and the other end movably connected to the gripper via a first rotating shaft. The gripper is rotatably connected to the fixed plate via a second rotating shaft. One end of the elastic element abuts against the fixed plate, and the other end abuts against the movable plate. Multiple lifting cylinders are provided, and these cylinders are respectively fixed below the material preparation station, the pre-assembly station, and the unloading station.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0021] like Figures 1-9As shown, an automatic assembly device for a transmission filter element according to an embodiment of the present invention is provided. The transmission filter element includes a plate 1 located at the bottom, a cover plate 2 covering the plate 1, and filter paper located between the plate 1 and the cover plate 2. The automatic assembly device is used to press the cover plate 2 onto the plate 1.
[0022] The automated assembly equipment includes a pre-assembly component 100, a pressing component 400, and a transport component (not shown). The pre-assembly component 100 includes a chassis 200 and an extrusion component 300 disposed above the chassis 200. The chassis 200 is configured to rotate and has at least one material preparation station 110, a pre-assembly station 120, and a material discharge station 130. The extrusion component 300 includes a support 310, a drive component 320 fixed on the support 310, and a pair of... Side pressing blocks 330, a pair of side pressing blocks 330 are located on both sides of the pre-assembly station 120. Driven by the drive assembly 320, the side pressing blocks 330 move towards the gearbox filter element and press the side surface 10 of the plate 1. The side surface 10 of the plate 1 is deformed under the pressure of the side pressing blocks 330 and latches onto the upper surface of the cover plate 2. The pressing assembly 400 is used to press the cover plate 2 onto the plate 1. The transport assembly is used to transfer the gearbox filter element located at the discharge station 130 to the pressing assembly 400. In this embodiment, there are two material preparation stations 110. The material preparation stations 110 are mainly used to place the gearbox filter elements to be processed, and are mainly placed manually. After the gearbox filter element to be processed is placed at the material preparation station 110, it moves to the pre-assembly station 120 under the rotation of the chassis 200. Under the action of the extrusion component 300, it is pre-assembled. Then, it continues to move to the discharge station 130 under the rotation of the chassis 200, waiting for the transport component to grab it and place it at the pressing component 400 for further pressing.
[0023] like Figure 9 As shown, the chassis 200 mainly utilizes the combined action of the motor 150 and the divider 160 to achieve its rotation function. Both the motor 150 and the divider 160 are fixed on the frame 140, and the divider 160 is connected to the motor 150 via a transmission connection. After the motor 150 starts, it transmits power to the divider 160. The divider 160, according to preset parameters, converts continuous rotation into precise intermittent motion, driving the chassis 200 to rotate at a certain angle. As the chassis 200 rotates, the synchronously rotating worktable 350 passes sequentially through the material preparation station 110, the pre-assembly station 120, and the unloading station 130.
[0024] like Figures 3-6As shown, the drive assembly 320 includes a drive motor 321, a drive gear 322 fixed on the shaft of the drive motor 321, and a pair of racks 323. The pair of racks 323 are located on both sides of the drive gear 322 and mesh with the drive gear 322 at the same time. Both racks 323 are slidably connected to the bracket 310. A connecting block 324 is fixed on the rack 323, and the connecting block 324 is fixedly connected to the side pressure block 330.
[0025] The bracket 310 is provided with a slide rail 325, and the rack 323 is provided with a slider 326 that is slidably connected to the slide rail 325.
[0026] The bracket 310 is also provided with an auxiliary pressing assembly 340, which includes a pair of pressing cylinders 341, a connecting plate 342 and an auxiliary pressing rod 343. The pair of pressing cylinders 341 are fixed on both sides of the bracket 310, the connecting plate 342 is fixedly connected to the piston rod of the pressing cylinder 341, and the auxiliary pressing rod 343 is fixedly connected to the connecting plate 342.
[0027] The automatic assembly equipment also includes multiple worktables 350, which are used to support the gearbox filter element. The worktables 350 rotate synchronously with the chassis 200 and pass through the material preparation station 110, the pre-assembly station 120 and the unloading station 130 in sequence.
[0028] The workbench 350 is provided with a groove 355 for storing the gearbox filter element, and the upper surface of the workbench 350 is provided with a through groove 356 communicating with the groove 355. The through groove 356 is used for the side pressure block 330 to pass through.
[0029] like Figure 8 As shown, the automatic assembly equipment also includes multiple auxiliary clamping components 360 that are arranged one-to-one with multiple worktables 350. Each auxiliary clamping component 360 includes a pair of grippers 361, which are located on the first side 351 and the second side 352 of the worktable 350 respectively for clamping the gearbox filter element. A pair of side pressure blocks 330 are located on the third side 353 and the fourth side 354 of the worktable 350 respectively. That is, there are two through slots 356, which are located on the third side 353 and the fourth side 354 of the worktable 350 respectively.
[0030] The auxiliary clamping assembly 360 also includes a fixed plate 362, a movable plate 363, a connecting rod 364, an elastic element 365, and a lifting cylinder 366, all fixedly connected to the worktable 350. The connecting rod 364 passes through the fixed plate 362, with one end fixedly connected to the movable plate 363 and the other end movably connected to the gripper 361 via a first rotating shaft 367. The gripper 361 is rotatably connected to the fixed plate 362 via a second rotating shaft 368. One end of the elastic element 365 abuts against the fixed plate 362, and the other end abuts against the movable plate 363. Multiple lifting cylinders 366 are provided, and these cylinders are fixed below the material preparation station 110, the pre-assembly station 120, and the unloading station 130, respectively. When the piston rod of the lifting cylinder 366 extends, the movable plate 363 rises under the action of the piston rod, thereby driving the gripper 361 to the open state via the connecting rod 364. When the piston rod of the lifting cylinder 366 retracts, the movable plate 363 descends under the action of the elastic element 365, thereby driving the gripper 361 to the clamping state via the connecting rod 364. This embodiment has four stations, each equipped with one lifting cylinder 366. It is worth noting that the lifting cylinders 366 do not rotate synchronously with the chassis 200; they are fixed on the bottom frame 140, while the other components in the auxiliary clamping assembly 360 rotate synchronously with the chassis 200.
[0031] The gripper 361 has an elongated hole 3610, through which the first rotating shaft 367 passes.
[0032] refer to Figure 1 The pressing assembly 400 includes a base 410, a pressing platform 420, a hydraulic cylinder, and a pressure plate 430 connected to the hydraulic cylinder. The pressing platform 420 is mounted on the base 410, and the pressure plate 430 is located directly above the pressing platform 420. The pressing assembly 400 is a finished product and will not be described in detail here.
[0033] The transport assembly includes a multi-axis motion module and a suction cup assembly 510. The suction cup assembly 510 is used to pick up the pre-assembled gearbox filter element and move it to the pressing assembly 400 under the drive of the multi-axis motion module. Of course, the transport assembly can also be transferred using a robotic arm. The robotic arm is a finished product and will not be described in detail here.
[0034] The working process of the automated assembly equipment is as follows: During the operation of the automatic gearbox filter assembly equipment, the rotation of the chassis 200 becomes the core driving force for the orderly progress of the entire assembly process. When the chassis 200 rotates, the worktable 350, which rotates synchronously with it, passes through the material preparation station 110, the pre-assembly station 120, and the unloading station 130 in sequence. At this time, the piston rod of the lifting cylinder 366 located below the material preparation station 110 extends, pushing the movable plate 363 to rise. Through the connecting rod 364, the gripper 361 opens. At this time, the manual person places the plate 1 of the gearbox filter element into the groove 355 of the worktable 350. After placement, the piston rod of the lifting cylinder 366 retracts, the movable plate 363 descends under the action of the elastic element 365, and the gripper 361 closes, firmly clamping the filter element on the worktable 350. As the chassis 200 rotates, the worktable 350 carrying the filter element arrives at the pre-assembly station 120. At the pre-assembly station 120, the drive assembly 320 begins operation. The drive motor 321 drives the drive gear 322 to rotate. Since a pair of racks 323 are located on both sides of the drive gear 322 and mesh with it, the rotation of the drive gear 322 drives the racks 323 to move simultaneously towards the gearbox filter element. The racks 323 drive the side pressure block 330 to move via the connecting block 324. The side pressure block 330 passes through the through slot 356 on the worktable 350, pressing the side 10 of the plate 1, deforming it and securing it to the upper surface of the cover plate 2. Simultaneously, the pair of downward pressing cylinders 341 of the auxiliary pressing assembly 340 actuate, driving the auxiliary pressure rod 343 downward via the connecting plate 342 to assist in fixing the filter element, ensuring the accuracy and stability of the pre-assembly process. After pre-assembly, the chassis 200 continues to rotate, and the worktable 350 transports the filter element to the unloading station 130. At this time, the transport component begins to operate, and its multi-axis motion module precisely controls the movement trajectory of the suction cup component 510 according to a preset program. The suction cup component 510 uses the principle of vacuum adsorption to firmly pick up the pre-assembled gearbox filter element, and under the drive of the multi-axis motion module, it moves smoothly and quickly above the pressing platform 420 of the pressing component 400. Subsequently, the suction cup component 510 releases the vacuum and accurately places the filter element on the pressing platform 420. The hydraulic cylinder of the pressing component 400 drives the pressure plate 430 to move downward, firmly pressing the cover plate 2 onto the plate 1, completing the final assembly of the gearbox filter element.
[0035] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
