[0039] Reference Figures 1 to 5 An embodiment of the present invention provides a transfer mechanism, which includes a frame 100, a driving assembly 200 and a check assembly 300.

[0040] The frame 100 is provided with a movable channel 110 opening upward, and two supporting blocks 120 located in the movable channel 110, with an avoidance gap S provided between the two supporting blocks 120. The movable channel 110, the supporting blocks 120 and the avoidance gap S are all extended in the front-to-back direction. The two supporting blocks 120 are used to respectively support the left bottom and the right bottom of the jig 600, so that the jig 600 can be movably arranged in the movable channel 110 in the front-to-back direction. The driving assembly 200 is provided on the frame 100, and the check assembly 300 is provided on the driving assembly 200. The check assembly 300 is provided with an abutment portion 321 that can resist pressure and rebound, and the abutment portion 321 is provided in the avoidance gap S.

[0041] It is understandable that the jig 600 can be placed in the moving channel 110 through the opening. When the jig 600 is placed in the moving channel 110 , the left bottom and the right bottom of the jig 600 are supported by the two supporting blocks 120 respectively.

[0042] When the driving assembly 200 drives the abutting portion 321 to move backward within the avoidance gap S, the abutting portion 321 pushes the front end of the jig 600 on the moving channel 110 to drive the jig 600 to move backward on the moving channel 110 .

[0043] When the driving assembly 200 drives the abutting portion 321 to move forward within the clearance S, the abutting portion 321 abuts against the rear end of the jig 600 on the movable channel 110 and, after being pressed, rebounds and moves sequentially to the bottom side and the front end of the jig 600. It is understood that when the abutting portion 321 moves to the front end of the jig 600, the abutting portion 321 can push the jig 600 backward on the movable channel 110 when it is ready to move backward.

[0044] Through the above structure, on the one hand, the driving component 200 can drive the abutment portion 321 to move backward in the avoidance gap S, so that the abutment portion 321 pushes the front end of the jig on the movable channel 110, so as to drive the jig 600 to move backward on the movable channel 110 to the corresponding work station to perform corresponding work on the valve bottom cup assembly 710 with the valve cover assembly 720 on the jig 600; on the other hand, the left bottom and the right bottom of the jig 600 on the movable channel 110 are respectively supported by two supporting blocks 120. When the valve bottom cup assembly 710 with the valve cover assembly 720 on the jig 600 is inspected, or riveted, or other work that requires a pressing action as a prerequisite, the bearing effect provided by the two supporting blocks 120 is sufficient to meet the requirements of the above work.

[0045] In this embodiment, referring to Figure 1 and Figure 3 The number of the check assemblies 300 is six, and the six check assemblies 300 are sequentially spaced apart in the front-to-back direction, and the distance between two adjacent check assemblies 300 is greater than the length of the fixture 600.

[0046] Through the above structure, the arrangement of the six check assemblies 300 can synchronously push the six jigs 600 on the moving channel 110 to move backward.

[0047] In some embodiments, three check assemblies 300 are provided, and the three check assemblies 300 are spaced apart in sequence along the front-to-back direction, and the distance between two adjacent check assemblies 300 is greater than the length of the fixture 600.

[0048] In this embodiment, referring to Figure 1 and Figure 2 The movable channel 110 includes a first channel section 111 and a second channel section 112 connected to each other in the front and rear directions. The first channel section 111 can receive the jig 600 through the corresponding opening portion. The frame 100 is provided with a limit block 130 arranged along the front and rear directions in the second channel section 112.

[0049] When the jig 600 moves from the first channel section 111 to the second channel section 112 , the limiting block 130 is located above the protrusion 610 on the right side of the jig 600 to prevent the jig 600 from escaping through the opening corresponding to the second channel section 112 .

[0050] It can be understood that when the jig 600 moves from the first channel section 111 to the second channel section 112, the left bottom and the right bottom of the jig 600 are still respectively abutted against the two supporting blocks 120, and the protrusion 610 on the right side of the jig 600 moves between the limit block 130 and the corresponding supporting block 120.

[0051] It can be understood that the jig 600 moves back to the corresponding workstation on the movable channel 110 . Specifically, the jig 600 moves back to the corresponding workstation on the second channel section 112 .

[0052] Through the above structure, the setting of the limit block 130 can improve the stability of the jig 600 when moving in the second channel section 112, and can improve the stability of the jig 600 when working on the valve bottom cup assembly 710 with the valve cover assembly 720.

[0053] The check assembly 300 includes a connecting seat 310 , a swing arm 320 and an elastic member.

[0054] Reference Figures 3 to 5 The connecting seat 310 is arranged on the driving assembly 200, the front end of the swing arm member 320 is rotatably connected to the connecting seat 310, the rear end of the swing arm member 320 is the above-mentioned abutment portion 321, and the elastic member is arranged between the swing arm member 320 and the connecting seat 310. The elastic member can drive the abutment portion 321 to swing upward to a preset height.

[0055] The contact portion 321 moves forward and then moves to the bottom side and the front end of the fixture 600 in sequence after being pressed and rebounded. Figure 3 The corresponding rear end of the jig 600 presses against the abutting portion 321 that moves forward. Under the action of the elastic member, the abutting portion 321 that is pressed downward continues to move forward in a state of abutting against the bottom side of the jig 600. When the abutting portion 321 continues to move forward until the abutting state with the bottom side of the jig 600 is released, under the action of the elastic member, the abutting portion 321 swings up to the front end of the jig 600.

[0056] The elastic member is provided between the swing arm member 320 and the connecting seat 310. For details, refer to Figure 4 and Figure 5 The bottom side of the swing arm 320 is provided with a first hole 322, the connecting seat 310 is provided with a second hole 311 located below the first hole 322, and the two ends of the elastic member are respectively inserted into the first hole 322 and the second hole 311.

[0059] It is understandable that when the rotating wheel 400 abuts against the fixture 600 on the moving channel 110 and moves forward, the rotating wheel 400 can rotate to reduce friction during movement.

[0060] In some embodiments, the rotating wheel 400 is rotatably connected to the left side of the abutting portion 321 .

[0061] In this embodiment, referring to Figure 1 and Figure 3 The frame 100 is provided with five first driving members 500, each of which is provided with a positioning block 510. The first driving members 500 can drive the positioning block 510 to extend, thereby abutting against the rear end of the corresponding jig 600 on the movable channel 110 to position the jig 600 at the corresponding position; the first driving members 500 can also drive the positioning block 510 to retract, thereby preventing the jig 600 from moving on the movable channel 110.

[0062] In this embodiment, the first driving member 500 is configured as a cylinder. Of course, in some embodiments, the first driving member 500 can be configured as an electric push rod, etc.

[0063] The driving assembly 200 includes a sliding frame 210 and a second driving member 220 .

[0064] Reference Figure 1 and Figure 3 The sliding frame 210 is slidably disposed on the frame 100, the connecting seat 310 is disposed on the sliding frame 210, and the second driving member 220 is disposed on the frame 100.
