The track switching component 3 is used for switching the connection between the working station A and the waiting stations on different track transmission units (when the first waiting station B and the fourth waiting station E at both ends of the first track transmission unit I are connected to the working station A, the second waiting station C and the third waiting station D at both ends of the second track transmission unit II are not connected to the working station A).

[0036] The X-type turnout intelligent switching platform of the present invention has four waiting stations and one working station. The four waiting stations are interconnected with the working stations in pairs (when the two waiting stations on one track transmission unit are connected with the working station at the same time, the two waiting stations on the other track transmission unit are not connected with the working station). When there are four vehicle models, a combination is formed to improve the transportation work efficiency. Therefore, the present invention has the characteristics of high flexibility and can improve the tact time of multi-model production. In order to reduce the floor space, the angle between the two track transmission units I and II can be selected to be a smaller angle, such as 15 to 45°.

[0037] In this embodiment, Figure 4 As shown, the track 1 includes a steel structure support 11 and a track body 12 arranged on the steel structure support 11. The steel structure support 11 and the track body 12 are disconnected at the intersection of two tracks 1, and the track switching assembly 3 is arranged at the disconnected position.

[0039] In this embodiment, Figure 6As shown, the base 31 is a frame base, the driving cylinder 32 of the segmented driving mechanism is arranged inside the frame base, the slide rail 33, the slider 34, the first segmented track 35 and the second segmented track 36 of the segmented driving mechanism are arranged on the top of the frame base, and the top of the frame base is also provided with a slider limit block 38 for limiting the movement range of the slider 34 and a slider position sensor 37 for sensing the movement position of the slider 34. The driving cylinder 32 is connected to the slider 34 through a connecting rod passing through the top of the frame base.

[0040] like Figure 5 As shown, the four waiting stations in this embodiment are all provided with a waiting station position sensor 19 for sensing whether the transfer trolley 2 has arrived at the corresponding waiting station and a waiting station buffer 18 for buffering the transfer trolley 2 .

[0041] like Figure 4 As shown, in this embodiment, work station A is provided with four work station position sensors 17, four groups of work station buffers 16, four groups of work station in-place positioning pins 15 and four groups of work station in-place guide wheels 14; the four work station position sensors 17 are respectively used to sense whether the transfer carts 2 carried by the four waiting stations B, C, D, and E have reached work station A; the four groups of work station buffers 16 are respectively used to buffer the transfer carts 2 carried by the four waiting stations; the four groups of work station in-place positioning pins 15 are respectively used to position the transfer carts 2 carried by the four waiting stations; the four groups of work station in-place guide wheels 14 are respectively used to accurately guide the transfer carts 2 carried by the four waiting stations into work station A.

[0042] The working principle of the present invention is:

[0043] When only one vehicle model is produced, the first waiting station B carries a transfer trolley, the second waiting station C, the third waiting station D, and the fourth waiting station E can be removed, and the system transmission only uses the working station A and the first waiting station B. The moving direction of the mobile trolley is from the first waiting station B to the working station A, and the track switching component 3 is not required.

[0044] When producing two or more vehicle models, the entire transmission system uses partial functions. The first waiting station B and the second waiting station C each carry a transfer trolley and move to the working station A respectively, and the track switching component 3 is not needed.

[0045] When producing three vehicle models, all functions of the entire transmission system are used. The first waiting station B, the second waiting station C, and the fourth waiting station E each carry a transfer trolley, and four track switching components 3 are required. When the transfer trolley moves from the first waiting station B to the working position A or from the fourth waiting station E to the working position A, the track switching component 3 connects the first track transmission unit.

[0046] When producing 4 models, all functions of the entire transmission system are fully used. The first waiting station B, the second waiting station C, the third waiting station D and the fourth waiting station E each carry a transfer trolley, and four track switching components 3 are required. When the transfer trolley moves from the second waiting station C to the working station A or from the third waiting station D to the working station A, the track switching component 3 connects the second track transmission unit.

[0047] During the movement, the power is driven by the motor on the transfer trolley to drive the gear and the X-transmission track rack 13, and then the six rollers on the transfer trolley roll on the corresponding track body 12 to achieve fast and quiet movement.

[0048] After the transfer trolley arrives at the working station or waiting station, the corresponding buffer plays a role in reducing the power. After the transfer trolley arrives at the working station A, the corresponding position sensor (usually a travel switch) senses that it is in place, and the work station in-place positioning pin extends and acts on the positioning transfer trolley to achieve precise positioning.

[0049] When the transfer trolley exceeds the travel limit, it touches the corresponding position sensor (usually a travel switch) and the system stops, making the system safer and more reliable.

[0050] The above description of the embodiments is to facilitate the understanding and use of the invention by those skilled in the art. It is obvious that those skilled in the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the present invention is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the scope of protection of the present invention.
