[0038] Preferably, the follower 72 includes a follower structure 721 and a Y-axis telescopic member 722 for causing the follower structure 721 to telescopically move along the Y-axis direction.

[0039] Preferably, the connecting groove 6 horizontally penetrates through the fixture base 1 along the Y-axis direction, and the Y-axis moving mechanism 42 can drive the connecting groove 6 of the fixture base 1 along the Y-axis direction to sleeved on the connecting wheel 5 of another fixture base 1 and limit the fixture base 1.

[0041] Preferably, a detection mechanism 10 is provided on one side of the long-axis mechanism 3.

[0044] The working principle of the present utility model:

[0045] In this embodiment, two long-axis mechanisms 3 and two short-axis mechanisms 4 form a rectangular meandering loop conveyor line. The two long-axis mechanisms 3 are arranged in parallel side by side. The two short-axis mechanisms 4 are parallel to each other. The two short-axis mechanisms 4 are respectively located on the left and right sides of the long-axis mechanism 3, so that the two adjacent ends of the two long-axis mechanisms 3 are transferred by the Y-axis moving mechanism 42 in the corresponding short-axis mechanism 4. One end of the two first X-axis linear guide rails 31 drives the second X-axis linear guide rail 41 to be respectively matched with the two first X-axis linear guide rails 31 through the Y-axis moving mechanism 42. When the first X-axis linear guide rail 31 in the front is matched and docked with the second X-axis linear guide rail 41, the slider 2 on the first X-axis linear guide rail 31 is driven by the driving mechanism 7 and slides into the second X-axis linear guide rail 41. The moving end of the Y-axis moving mechanism 42 drives the second X-axis linear guide rail 41 with the slider 2 to move backward to be matched with the first X-axis moving mechanism 71 at the rear. The slider 2 on the second X-axis linear mechanism slides into the first X-axis linear guide rail 31 at the rear, completing the transfer of the slider 2. Since the fixture base 1 is installed on the slider 2, the conversion of the fixture base 1 is completed. Similarly, the two adjacent ends on the other side of the two first X-axis linear guide rails 31 are also transferred through the adjacent short-axis mechanism 4, thus forming a complete closed meandering loop conveyor line.

[0046] In this embodiment, every two sliders 2 are provided corresponding to one fixture base 1, that is, two sliders 2 are fixedly connected to one fixture base 1 and move together. A plurality of fixture bases 1 are sequentially connected on each first X-axis linear guide rail 31. The driving mechanism 7 drives the follower 72 to move along the X-axis direction through the X-axis moving mechanism 71, as shown in the appendix Figure 1The X-axis direction is the horizontal left-right direction, and the Y-axis direction is the vertical up-down direction. The follower 72 includes a follower structure 721 and a Y-axis telescopic member 722. The Y-axis telescopic member 722 can select a telescopic mechanism such as a cylinder to drive the follower structure 721 to reciprocate back and forth, that is, move in the Y-axis direction. A cam 9 is provided at one end of the follower structure 721 close to the corresponding first X-axis linear guide 31. The telescopic end of the Y-axis telescopic member 722 drives the cam 9 to extend into the follower groove 8 for cooperation. When the X-axis drives the follower structure 721 to move left and right, it will drive the cam 9 that cooperates with the follower groove 8 to move left and right, thereby causing the fixture base 1 to move left and right. Further, the connected fixture base 1 also moves accordingly, so as to drive all the fixture bases 1 on the first X-axis linear guide 31 where it is located. In addition, the first X-axis linear guide 31, the slider 2, the Y-axis moving mechanism 42, and the X-axis moving mechanism 71 can also select a linear module to drive the fixture base 1. Both the cam 9 and the connecting wheel 5 are selected as wheel-shaped structures, which are convenient for wear during the cooperation process, improve the cooperation efficiency, and reduce losses.

[0047] The follower groove 8 is located in the middle of the fixture base 1. The follower groove 8 of each fixture base 1 can be matched with the cam 9. Therefore, the cam 9 on the follower structure 721 is promoted by the Y-axis telescopic member 722 to replace the follower grooves 8 of different fixture bases 1 for cooperation, so as to avoid the insufficient movement stroke of the fixture base 1 provided by the X-axis moving mechanism 71.

[0048] The connecting groove 6 is horizontally arranged front and back at one end of the fixture base 1. The connecting wheel 5 of the fixture base 1 can move back and forth and extend into the connecting groove 6 of another fixture base 1 to achieve detachable cooperation. Since the first X-axis linear guide 31 ensures that the fixture base 1 cannot move back and forth, the fixture base 1 can only move along the X-axis, which limits the position of the die base on the same X-axis linear guide in the Y-axis direction. Only during the Y-axis moving mechanism 42 of the short-axis mechanism 4, the second X-axis linear guide 41, and the connecting wheel 5 of the fixture base 1 located on the second X-axis linear guide 41 can move back and forth and extend into the connecting groove 6 of another fixture base 1. The connecting groove 6 is connected front and back and is wider outside and narrower inside, which has a guiding effect and is convenient for the connecting wheel 5 to slide into the connecting groove 6.

[0049] The detection mechanism 10 on one side of the long-axis mechanism 3 can detect the position of the fixture base 1 and the quality of the fixture base 1. The through hole opened at the bottom of the connecting groove 6 can further limit the position of the connecting wheel 5, or a detection unit is arranged below the through hole to detect whether the connecting wheel 5 is on the connecting groove 6.

[0050] The technical means disclosed by the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
