[0022] The automatic assembly equipment includes a pre-assembly component 100, a press assembly 400 and a transport component (not shown in the figure). The pre-assembly component 100 includes a chassis 200 and an extrusion component 300 arranged above the chassis 200. The chassis 200 is configured to be rotatable and is provided with at least one material preparation station 110, a pre-assembly station 120 and a discharge station 130. The extrusion component 300 includes a bracket 310, a driving component 320 fixed to the bracket 310 and a pair of A pair of side pressure blocks 330 are located on either side of the pre-assembly station 120. Driven by the drive assembly 320, the side pressure blocks 330 move toward the transmission filter element and press the side surface 10 of the plate 1. The side surface 10 of the plate 1 deforms under the pressure of the side pressure blocks 330 and snaps onto the upper surface of the cover plate 2. The press-fit assembly 400 is used to press the cover plate 2 onto the plate 1. The transport assembly is used to transfer the transmission filter element located at the discharge station 130 to the press-fit assembly 400. In this embodiment, two material preparation stations 110 are provided. The material preparation stations 110 are primarily used to place the transmission filter element to be processed, and are mainly placed manually. After the gearbox filter element to be processed is placed at the preparation station 110, it moves to the pre-assembly station 120 under the rotation of the chassis 200, and is pre-assembled under the action of the extrusion component 300. 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 take it to the pressing component 400 for further pressing.

[0023] like Figure 9 As shown, chassis 200 primarily utilizes the combined action of motor 150 and divider 160 to achieve its self-rotation function. Both motor 150 and divider 160 are fixed to frame 140, and divider 160 is in driving connection with motor 150. After motor 150 is activated, it transmits power to divider 160. Divider 160 converts continuous rotation into precise intermittent motion according to pre-set parameters, driving chassis 200 to rotate at a predetermined angle. As chassis 200 rotates, worktable 350, which rotates synchronously with it, passes through material preparation station 110, pre-assembly station 120, and unloading station 130 in sequence.

[0024] like Figure 3-Figure 6As shown, the driving assembly 320 includes a driving motor 321, a driving gear 322 fixed on the rotating shaft of the driving motor 321, and a pair of racks 323. The pair of racks 323 are respectively located on both sides of the driving gear 322 and are engaged with the driving gear 322 at the same time. The pair of racks 323 are both 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] A slide rail 325 is provided on the bracket 310 , and a slider 326 slidably connected to the slide rail 325 is provided on the rack 323 .

[0026] An auxiliary pressing assembly 340 is also provided on the bracket 310. The auxiliary pressing assembly 340 includes a pair of downward pressing cylinders 341, a connecting plate 342 and an auxiliary pressing rod 343. The pair of downward pressing cylinders 341 are respectively fixed on both sides of the bracket 310, the connecting plate 342 is fixedly connected to the piston rod of the downward pressing cylinder 341, and the auxiliary pressing rod 343 is fixedly connected to the connecting plate 342.

[0027] The automatic assembly equipment further includes a plurality of workbenches 350 , which are used to support the transmission filter element. The workbenches 350 rotate synchronously with the chassis 200 and pass through the material preparation station 110 , the pre-assembly station 120 and the discharge station 130 in sequence.

[0028] The workbench 350 is provided with a groove 355 for receiving the transmission filter element, and the upper surface of the workbench 350 is provided with a through groove 356 communicating with the groove 355 , and 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 a plurality of auxiliary clamping assemblies 360 arranged in a one-to-one correspondence with the plurality of workbenches 350. The auxiliary clamping assemblies 360 include a pair of clamping jaws 361, which are respectively located on the first side 351 and the second side 352 of the workbench 350 and are used to clamp the transmission filter element. A pair of side pressure blocks 330 are respectively located on the third side 353 and the fourth side 354 of the workbench 350, that is, two through grooves 356 are provided, and are respectively located on the third side 353 and the fourth side 354 of the workbench 350.

[0030] The auxiliary clamping assembly 360 also includes a fixed plate 362 fixedly connected to the workbench 350, a movable plate 363, a connecting rod 364, an elastic member 365 and a lifting cylinder 366. The connecting rod 364 passes through the fixed plate 362, and one end of the connecting rod 364 is fixedly connected to the movable plate 363, and the other end is movably connected to the clamping claw 361 through a first rotating shaft 367. The clamping claw 361 is rotatably connected to the fixed plate 362 through a second rotating shaft 368. One end of the elastic member 365 abuts against the fixed plate 362, and the other end abuts against the movable plate 363. A plurality of lifting cylinders 366 are provided, and the plurality of lifting cylinders 366 are respectively fixed below the material preparation station 110, the pre-assembly station 120, and the discharge station 130. When the piston rod of the lifting cylinder 366 is extended, the movable plate 363 is acted upon by the piston rod and then drives the clamping jaws 361 to an open state through the connecting rod 364. When the piston rod of the lifting cylinder 366 is retracted, the movable plate 363 is acted upon by the elastic member 365 and then drives the clamping jaws 361 to a clamped state through the connecting rod 364. This embodiment has four stations, each of which is provided with a lifting cylinder 366. It is worth noting that the lifting cylinders 366 do not rotate synchronously with the chassis 200. The lifting cylinders 366 are fixed to the bottom frame 140, while the other components of the auxiliary clamping assembly 360 rotate synchronously with the chassis 200.

[0031] A long hole 3610 is defined in the clamping jaw 361 , and the first rotating shaft 367 passes through the long hole 3610 .

[0032] refer to Figure 1 The press assembly 400 includes a base 410, a press platform 420, a hydraulic cylinder, and a press plate 430 connected to the hydraulic cylinder. The press platform 420 is set on the base 410, and the press plate 430 is located directly above the press platform 420. The press assembly 400 is a finished device 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 absorb the pre-assembled transmission filter element and, driven by the multi-axis motion module, move it to the press assembly 400. Of course, the transport assembly can also be transferred using a robotic arm. The robotic arm is a finished device and will not be described in detail here.

[0034] The working process of automatic assembly equipment is as follows: During the operation of the automatic transmission filter assembly equipment, the rotation of the chassis 200 becomes the core driving force for the orderly progress of the entire assembly process. As the chassis 200 rotates, the worktable 350, which rotates synchronously with it, passes through the preparation station 110, the pre-assembly station 120, and the discharge 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 up, and driving the clamping claw 361 to open through the connecting rod 364. At this time, the plate 1 of the gearbox filter element is manually placed in the groove 355 of the workbench 350. After the placement is completed, the piston rod of the lifting cylinder 366 contracts, and the movable plate 363 descends under the action of the elastic member 365. The clamping claw 361 closes, clamping the filter element firmly on the workbench 350. As the chassis 200 rotates, the workbench 350 carries the filter element to the pre-assembly station 120. At the pre-assembly station 120, the drive assembly 320 starts working, and the drive motor 321 drives the active gear 322 to rotate. Since a pair of racks 323 are respectively located on both sides of the active gear 322 and mesh with it, the rotation of the active gear 322 will drive the pair of racks 323 to move simultaneously in the direction close to the transmission filter element. The rack 323 drives the side pressure block 330 to move through the connecting block 324. The side pressure block 330 passes through the through slot 356 on the workbench 350, squeezes the side 10 of the plate 1, and deforms the side 10 of the plate 1 and buckles the upper surface of the cover 2. At the same time, the pair of downward pressure cylinders 341 of the auxiliary pressing assembly 340 are actuated, driving the auxiliary pressure rod 343 to press down through the connecting plate 342 to assist in fixing the filter element, thereby ensuring the accuracy and stability of the pre-assembly process. After the pre-assembly is completed, the chassis 200 continues to rotate, and the workbench 350 transports the filter element to the discharge station 130. At this time, the transport component starts to operate, and the multi-axis motion module it contains accurately controls the movement trajectory of the suction cup assembly 510 according to the preset program. The suction cup assembly 510 uses the vacuum adsorption principle to tightly absorb the pre-assembled transmission filter element, and under the drive of the multi-axis motion module, it moves smoothly and quickly to the top of the pressing platform 420 of the pressing assembly 400. Subsequently, the suction cup assembly 510 releases the vacuum and accurately places the filter element on the pressing platform 420. The hydraulic cylinder of the pressing assembly 400 drives the pressing plate 430 to move downward, firmly pressing the cover plate 2 onto the plate 1, completing the final assembly of the transmission filter element.

[0035] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
