DETAILED DESCRIPTION

[0066] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more explicit definition of the protection scope of the present invention. Obviously, the embodiments described in the present invention are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0067] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0068] Embodiment 1: The specific structure of the present invention is as follows:

[0069] Please refer to the attached Figure 1-8 The present invention provides a circulating transmission device with a track-type carrier device, including a front-end conveying group 100, a rear-end conveying group 300, at least one intermediate conveying group 200, at least one carrier fixture 3 and multiple positioning devices 5.

[0070] The front conveying group 100 has a first housing and a lifting conveying mechanism 2 disposed in the first housing. The lifting conveying mechanism 2 includes a lifting part 21 and a first conveying line 22 which is drivingly connected to the lifting part 21 and can be driven by the lifting part 21 to perform lifting actions.

[0071] The rear conveying group 300 has the same structure as the front conveying group 100;

[0072] At least one intermediate conveying group 200, at least one intermediate conveying group 200 is arranged between the front conveying group 100 and the rear conveying group 300 and is spliced ​​in sequence to form a linear splicing structure, the intermediate conveying group 200 has a second housing, an upward conveying line 11 arranged in the second housing, and a downward conveying line 12 arranged in the second housing, and the first conveying line 22 is alternately connected with the upward conveying line 11 and the downward conveying line 12 by lifting;

[0073] At least one set of carrier fixtures 3, each of which can be driven by the first conveyor line 22, the upward conveyor line 11 and the downward conveyor line 12 to move in a linear manner through friction;

[0074] Multiple groups of positioning devices 5 The positioning devices 5 have a clamping mechanism for fixing and releasing the carrier fixture 3 , and the positioning devices 5 are provided at one node position of the first conveyor line 22 and at least one node position of the upward conveyor line 11 .

[0075] by Figure 1 For example, Figure 1 In the embodiment, a front conveying group 100, a middle conveying group 200 and a rear conveying group 300 are sequentially connected. The lifting part 21 of the front conveying group 100 and the lifting part 21 of the rear conveying group 300 drive their respective first conveying lines 22 to rise and fall. The first conveying line 22 of the front conveying group 100 is connected at the beginning of the upward conveying line 11 and the end of the downward conveying line 12, and the first conveying line 22 of the rear conveying group 300 is connected at the end of the upward conveying line 11 and the beginning of the downward conveying line 12.

[0076] When the first conveyor line 22 at the front end is connected with the down conveyor line 12, the first conveyor line 22 at the front end and the down conveyor line 12 are transported in the same direction and to the left, and the down conveyor line 12 delivers the reflowed carrier fixture 3 to the first conveyor line 22 at the front end. After the first conveyor line 22 at the front end receives the carrier fixture 3, it is fixed by the positioning device 5 at the front end. At this time, the lifting part 21 at the front end drives the first conveyor line 22 at the front end to rise to connect with the up conveyor line 11, and at the same time, it is fed to the carrier fixture 3 through the nearby feeding equipment. At this time, the first conveyor line 22 at the front end reverses to the right to transport the carrier fixture 3.

[0077] The positioning device 5 at the front end releases the carrier fixture 3, and the carrier fixture 3 is sent to the upward conveyor line 11 and runs to the positioning device 5 on the intermediate conveyor group 200. Since the number of intermediate conveyor groups 200 is set to at least one group, the positioning device 5 is set at the corresponding processing position as needed. When the carrier fixture 3 reaches each processing position, it is fixed by the positioning device 5, and the processing equipment set on the adjacent side of the intermediate conveyor group 200 processes the processed items on the carrier fixture 3, and finally sent to the first conveyor line 22 at the rear end and fixed by the positioning device 5 at the rear end. The nearby unloading equipment takes out the processed items, and the lifting part 21 at the rear end drives the first conveyor line 22 at the rear end to descend to connect with the downward conveyor line 12. At the same time, the first conveyor line 22 at the rear end reverses to the left for transportation. The downward conveyor line 12 receives the empty carrier fixture 3 and flows back to the first conveyor line 22 at the front end.

[0078] The above-mentioned moving mode of the stage fixture 3 is that the stage fixture 3 moves along the guide rail and the stage fixture 3 is driven by the contact friction force generated between each conveying line and the stage fixture 3 .
