[0031] Referring to Figures 1-6 , according to an embodiment of a filter screen assembling machine of the present utility model, it includes a processing table 11, a bearing table 12 is fixedly arranged on the tabletop of the processing table 11, a plurality of bosses are arranged in the front and back of the upper side surface of the bearing table 12, and an arc-shaped groove 13 for placing a filter screen is arranged in the upper side surface of the boss;

[0032] An installation groove 14 is arranged in each of the left and right side surfaces of the bearing table 12, an installation plate 15 is hinged in the installation groove 14 through a rotating shaft, one end of the installation plate 15 away from the bearing table 12 extends upward, and a plurality of locking plates 16 in the same front and back position as the arc-shaped groove 13 are arranged at the end of the installation plate 15 extending upward. The side surface of the locking plate 16 close to the bearing table 12 is an arc surface. A locking mechanism for controlling the angles of the installation plate 15 and the locking plates 16 is further arranged on the processing table 11. That is, when the installation plate 15 swings upward and the locking plates 16 approach each other until they fit, if the workpiece and the filter screen are placed in the arc-shaped groove 13 at this time, the filter screen will be extruded by the inner curved surface of the locking plate 16 and attached to the workpiece, and then further fixed by a laser welding machine.

[0033] In order to facilitate the automatic positioning of the workpiece and placing it in the arc-shaped groove 13, a workpiece clamping mechanism is further included. The workpiece clamping mechanism includes a fixing plate 17 arranged on the processing table 11. A sliding plate 18 is slidably connected to the front side surface of the fixing plate 17, and a clamp for clamping the workpiece is arranged on the sliding plate 18. In this embodiment, the clamp includes a clamping barrel 19 fixed on the sliding plate 18 through an installation plate. A fixing rod 20 is fixedly arranged in the clamping barrel 19, and an outer support rod 21 is integrally formed at the end of the fixing rod 20.

[0034] In order to enable the workpiece sleeved on the outer support rod 21 to automatically sink into the arc-shaped groove 13, a first cylinder 22 is arranged on the processing table 11. The end of the first piston rod extending out of the first cylinder 22 is equipped with a connecting plate 23 connected to the sliding plate 18. That is, the staff can control the up and down movement of the outer support rod 21 and the workpiece by controlling the first cylinder 22. When the outer support rod 21 moves to the lowermost side, the workpiece sleeved on the outer support rod 21 can be placed in the arc-shaped groove 13.

[0035] In addition, in order to prevent the workpiece sleeved on the outer support rod 21 from moving forward when the outer support rod 21 moves downward, a spring plate 29 is further arranged on the bearing table 12. A contact plate 30 is slidably connected back and forth in the spring plate 29, and the front end of the contact plate 30 is connected to the inside of the spring plate 29 through a second spring. The contact plate 30 is located on the front side of the convex platform. An inclined chamfer is formed between the upper side surface and the rear side surface of the contact plate 30. When the outer support rod 21 moves downward, the workpiece sleeved on it will first adhere to the inclined angle on the contact plate 30 and be pushed backward and positioned by the second spring and the contact plate 30.

[0036] In this embodiment, the locking mechanism includes two vertical second cylinders 24 arranged in the processing table 11. The end of the second piston rod extending out of the second cylinder 24 is equipped with a support plate 25. The support plate 25 is close to the lower side surface of the mounting plate 15. That is, the staff can control the up and down position of the support plate 25 by controlling the second cylinder 24. During the upward movement of the support plate 25, the support plate 25 can push against the mounting plate 15 and make the locking plates 16 approach each other. When the support plate 25 moves to the uppermost side, the ends of the two locking plates 16 are fitted with each other to press the filter screen located in the arc-shaped groove 13 against the workpiece.

[0037] In order to enable the mounting plate 15 to reset and the locking plate 16 to droop downward after the support plate 25 sinks, a torsion spring 26 is sleeved on the rotating shaft. The two ends of the torsion spring 26 are respectively attached to the mounting plate 15 and the wall surface of the mounting groove 14.

[0038] In the second embodiment of the locking mechanism, in order to reduce the wear between the support plate 25 and the mounting plate 15 when the support plate 25 moves upward, runner wheels 27 are installed on the front and rear sides of the support plate 25. The runner wheels 27 are attached to the lower side surface of the mounting plate 15. In this embodiment, the runner wheels 27 are used to replace the direct contact between the support plate 25 and the mounting plate 15, so that the sliding friction when the support plate 25 rises becomes rolling friction, reducing noise and wear.

[0039] In the second embodiment of the filter screen assembling machine, a pre-positioning mechanism is further included. The pre-positioning mechanism includes a through hole disposed within the curved surface of the arc-shaped groove 13. A bearing platform is arranged within the processing table 11. The upper side surface of the bearing platform is connected to a plug rod 28 through a first spring. The plug rod 28 penetrates through the through hole and extends into the arc-shaped groove 13.

[0040] Moreover, a cutting mechanism is further included. The cutting mechanism includes a fixed platform installed on the processing table 11. A third air cylinder 31 is arranged on the fixed platform. The end of a third piston rod extending out of the third air cylinder 31 is equipped with a cross-cutting knife 32. The above-mentioned cross-cutting knife 32 is located on the left side of the above-mentioned convex platform and can move left and right. The cross-cutting knife 32 is used to cut off the redundant filter screen.

[0041] Specific filter screen assembling process:

[0042] There are multiple annular grooves arranged front and back within the workpiece, and oil passing holes are provided within the annular grooves. The filter screen needs to be wound around the annular grooves and cover the oil passing holes.

[0043] First, the worker sleeves the workpiece onto the outer support rod 21 and places the sheet-shaped filter screen within the arc-shaped groove 13. Then, the first air cylinder 22 controls the downward movement of the outer support rod 21. During this process, the workpiece will be pushed backward by the abutting plate 30, and the annular grooves within the workpiece will be aligned with the front and back positions of the arc-shaped groove 13. Moreover, during the downward movement of the outer support rod 21, the plug rod 28 will first abut against the filter screen and the workpiece for pre-positioning. After the outer support rod 21 moves to the lowermost side, the plug rod 28 completely enters the through hole.

[0044] After the outer support rod 21 moves to the lowermost side, the second air cylinder 24 controls the upward movement of the support plate 25, and upwardly pushes the mounting plate 15 through the runner 27, thereby causing the two locking plates 16 to approach each other. When the two locking plates 16 are mutually engaged, the pressing of the filter screen located within the arc-shaped groove 13 is completed.

[0045] After pressing, the redundant filter screen will extend to the upper side of the locking plate 16. Then, the third air cylinder 31 controls the rightward movement of the cross-cutting knife 32 and cuts off the redundant filter screen. Then, the cross-cutting knife 32 resets to the left.

[0046] Then, the support plate 25 moves downward, and the mounting plates 15 move away from each other under the action of the torsion spring 26. Then, the outer support rod 21 can rise, and the worker can remove the workpiece on the outer support rod 21.

[0047] It should be noted that the above-mentioned workpiece includes but is not limited to a VVT solenoid valve with a model number of 06L 109 257F.

[0048] The above are only specific embodiments of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
