[0029] like Figures 1 to 5As shown, the present application provides a rail transport device, which includes: a rail assembly 100, a carrier assembly 200, and a first positioning assembly 300. The rail assembly 100 includes a transport rail 110 and a mounting seat 120. The mounting seat 120 is slidably assembled on the transport rail 110. The carrier assembly 200 is installed based on the mounting seat 120. The carrier assembly 200 includes a fixture plate 210, and the fixture plate 210 is provided with positioning holes 212.

[0030] The first positioning assembly 300 includes a first driving device 310, an inclined slot block 320, a first follower wheel 330, a second follower wheel 340, a first positioning plate 350, and a second positioning plate 360. The first driving device 310 is fixedly connected to the inclined slot block 320. The inclined slot block 320 is provided with a first inclined slot 321 and a second inclined slot 322. The first follower wheel 330 is rotatably disposed in the first inclined slot 321, and the second follower wheel 340 is rotatably disposed in the second inclined slot 322. The first positioning plate 350 and the second positioning plate 360 ​​are respectively located on both sides of the inclined slot block 320, and the first positioning plate 350 is fixedly connected to the first follower wheel 330, the second positioning plate 360 ​​is fixedly connected to the second follower wheel 340, and the second positioning plate 350 is fixedly connected to the second follower wheel 340. The positioning plate 360 ​​is L-shaped, and the second positioning plate 360 ​​extends to the top of the first positioning plate 350. The end of the second positioning plate 360 ​​close to the first positioning plate 350 is provided with a positioning pin 361, and the positioning pin 361 matches the positioning hole 212. The first inclined groove 321 and the second inclined groove 322 have opposite inclinations, so that under the movement of the first inclined groove 321 and the second inclined groove 322, the first follower wheel 330 and the second follower wheel 340 can respectively drive the first positioning plate 350 and the second positioning plate 360 ​​to move in opposite directions, so that the first positioning plate 350 and the second positioning plate 360 ​​clamp and fix the fixture plate 210, and the positioning pin 361 is inserted into the positioning hole 212.

[0031] In a specific embodiment, the track assembly 100 is the basic structure of the entire device, the transport track 110 provides a sliding path for the mounting seat 120, the mounting seat 120 is a component connecting the carrier assembly 200 and the transport track 110, and there are several mounting seats 120, and the mounting seats 120 can move freely on the transport track 110. The carrier assembly 200 is arranged on the mounting seat 120 to realize the material transportation function. The fixture plate 210 in the carrier assembly 200 is a platform for placing the material to be transported, and there are several positioning holes 212. The positioning holes 212 run through the fixture plate 210. The positioning holes 212 are arranged to cooperate with the first positioning assembly 300 to achieve precise positioning. The shape and size of the fixture plate 210 can be designed according to the shape and size of the actual material.

[0032] The first driving device 310 is a component that provides power. In this embodiment, the first driving device 310 is a cylinder. The first driving device 310 is horizontally arranged and is used to push the chute block 320 to move. The chute block 320 is roughly in the shape of a rectangular parallelepiped. The chute block 320 is fixedly connected to the output end of the first driving device 310. The first chute 321 and the second chute 322 on the chute block 320 are transversely arranged slots with a certain inclination angle. The first chute 321 and the second chute 322 have the same inclination angle but opposite inclination directions. This opposite inclination trend causes the first follower wheel 330 and the second follower wheel 340 respectively located in the first chute 321 and the second chute 322 to produce displacements in different directions when the chute block 320 moves. The first follower wheel 330 and the second follower wheel 340 are cylindrical and arranged horizontally, and are used to convert the horizontal movement of the chute block 320 into the vertical movement of the first positioning plate 350 and the second positioning plate 360. The first positioning plate 350 is a rectangular plate, and the first positioning plate 350 is arranged vertically. The first positioning plate 350 is connected to the first follower wheel 330, and the second positioning plate 360 ​​is L-shaped, and the second positioning plate 360 ​​is connected to the second follower wheel 340, and one end of the second positioning plate 360 ​​extends above the first positioning plate 350, and a positioning pin 361 is provided at one end of the second positioning plate 360 ​​close to the first positioning plate 350, and the number and shape of the positioning pin 361 match the positioning hole 212.The horizontal height of one end of the first inclined slot 321 close to the first driving device 310 is higher than the horizontal height of one end of the first inclined slot 321 away from the first driving device 310, and the horizontal height of one end of the second inclined slot 322 close to the first driving device 310 is lower than the horizontal height of one end of the second inclined slot 322 away from the first driving device 310. When the first driving device 310 is in a retracted state, the first follower wheel 330 is in a low horizontal position in the first inclined slot 321, and the second follower wheel 340 is in a high horizontal position in the second inclined slot 322. At this time, the first positioning plate 350 and the second positioning plate 360 ​​are in an open state. After the fixture plate 210 moves with the mounting seat 120 to between the first positioning plate 350 and the second positioning plate 360 ​​in the open state, the mounting seat 120 stops moving, and the output end of the first driving device 310 extends, so that the first The inclined groove 321 and the second inclined groove 322 move in the horizontal direction. By fixing the first positioning plate 350 fixedly connected to the first follower wheel 330 and the second positioning plate 360 ​​fixedly connected to the second follower wheel 340 in the horizontal direction, the first follower wheel 330 drives the first positioning plate 350 to move to a high horizontal position in the first inclined groove 321, and the second follower wheel 340 drives the second positioning plate 360 ​​to move to a low horizontal position in the second inclined groove 322, that is, the first positioning plate 350 rises vertically and the second positioning plate 360 ​​falls vertically, so that the first positioning plate 350 and the second positioning plate 360 ​​clamp and fix the fixture plate 210 to realize the positioning of the fixture plate 210 in the vertical direction, and the positioning pin 361 on the second positioning plate 360 ​​will be inserted into the positioning hole 212 to realize the positioning of the fixture plate 210 in the horizontal direction.

[0033] In summary, by utilizing the cooperation between the inclined slot block 320 and the first follower wheel 330 and the second follower wheel 340, the first positioning plate 350 and the second positioning plate 360 ​​can position the fixture plate 210 in all directions. Compared with the traditional positioning method, the positioning accuracy is higher and can meet the production process requirements with higher requirements for material positioning.

[0034] like Figure 3 and Figure 5 As shown, the first positioning assembly 300 also includes a fixing frame 370, the fixing frame 370 includes a first limiting groove 371 and a second limiting groove 372, the first positioning plate 350 and the second positioning plate 360 ​​are respectively slidably assembled in the first limiting groove 371 and the second limiting groove 372, and the first limiting groove 371 and the second limiting groove 372 are used to limit the horizontal movement of the first positioning plate 350 and the second positioning plate 360.

[0035] In a specific embodiment, the fixing frame 370 is used to provide stable support and guidance for the first positioning plate 350 and the second positioning plate 360. The first limiting groove 371 and the second limiting groove 372 are rectangular grooves, and the first limiting groove 371 and the second limiting groove 372 are respectively adapted to the first positioning plate 350 and the second positioning plate 360. The shape and size of the first limiting groove 371 and the second limiting groove 372 can ensure that the first positioning plate 350 and the second positioning plate 360 ​​slide smoothly in the vertical direction, and also effectively limit the displacement of the first positioning plate 350 and the second positioning plate 360 ​​in the horizontal direction. When the first positioning plate 350 and the second positioning plate 360 ​​move in the vertical direction, the groove walls of the first limiting groove 371 and the second limiting groove 372 can prevent the first positioning plate 350 and the second positioning plate 360 ​​from shaking, thereby ensuring the accuracy and stability of positioning.

[0036] like Figure 2 As shown, the mounting seat 120 includes a first mounting plate 121 , the carrier assembly 200 is mounted based on the first mounting plate 121 , and a flexible plate 122 is provided between the first mounting plate 121 and the carrier assembly 200 .

[0037] In a specific embodiment, the first assembly plate 121 in the mounting seat 120 is a basic platform for installing the carrier assembly 200. The first assembly plate 121 is a horizontally arranged rectangular plate. A layer of flexible plate 122 is provided on the side of the first assembly plate 121 close to the carrier assembly 200. The flexible plate 122 is attached to the surface of the first assembly plate 121. The flexible plate 122 is located between the first assembly plate 121 and the carrier assembly 200. The flexible plate 122 is made of elastic materials such as rubber plates or silicone plates. The flexible plate 122 plays a role in buffering and shock absorption. During transportation, when the device is subjected to vibration or impact, the flexible plate 122 can absorb part of the energy, reduce the impact of vibration on the material on the carrier assembly 200, and prevent the material from being damaged or displaced due to vibration. At the same time, the flexible plate 122 can also effectively prevent the first positioning assembly 300 from damaging the equipment due to excessive pressure caused by positioning errors when positioning the fixture plate 210.

[0038] In summary, the presence of the flexible plate 122 improves the transportation stability and safety of the rail transportation device, reduces the impact of vibration on the carrier assembly 200, helps to extend the service life of the entire device, and improves the reliability of the equipment.

[0039] like Figure 2 As shown, the carrier assembly 200 also includes a base plate 220, a spring 230 and a screw 240. The carrier assembly 200 is installed based on the base plate 220. The screw 240 passes through the base plate 220 and the first assembly plate 121. The spring 230 is sleeved on the screw 240. The spring 230 presses the base plate 220 toward the first assembly plate 121, and the base plate 220 can slide relative to the first assembly plate 121.

[0040] In a specific embodiment, the substrate 220 is the installation base of the carrier assembly 200. The substrate 220 is a horizontally arranged rectangular plate. The shape of the substrate 220 matches the shape of the flexible board 122. The substrate 220 is attached to the side of the flexible board 122 away from the first assembly plate 121. A screw 240 is provided at each of the four corners of the substrate 220. The screw 240 passes through the substrate 220, the flexible board 122 and the first assembly plate 121. A spring 230 is sleeved on the screw 240. One end of the spring 230 conflicts with the end of the screw 240, and the other end of the spring 230 conflicts with the upper surface of the substrate 220. The spring 230 applies a force to the substrate 220 toward the first assembly plate 121, so that the substrate 220 can maintain a relatively stable state.

[0041] To summarize, the spring 230 applies force to the substrate 220 so that the substrate 220 can be relatively stably installed on the first assembly plate 121. At the same time, the substrate 220 can also move relative to the first assembly plate 121 under the action of external force, so that when the positioning of the first positioning assembly 300 is inaccurate, the position of the carrier assembly 200 can be manually adjusted so that the fixture plate 210 moves to an accurate positioning position.

[0042] like Figure 4 As shown, the first positioning assembly 300 further includes a first connecting rod 380 and a second connecting rod 390 . The first connecting rod 380 connects the first follower wheel 330 and the first positioning plate 350 , and the second connecting rod 390 connects the second follower wheel 340 and the second positioning plate 360 ​​.

[0043] In a specific embodiment, the first connecting rod 380 and the second connecting rod 390 are transmission connecting parts in the first positioning assembly 300. The first connecting rod 380 and the second connecting rod 390 are both cylindrical and horizontally arranged. One end of the first connecting rod 380 is connected to the center position of the first follower wheel 330 and the other end is fixedly connected to the first positioning plate 350. One end of the second connecting rod 390 is connected to the center position of the second follower wheel 340 and the other end is fixedly connected to the second positioning plate 360. When the first follower wheel 330 moves up and down in the first chute 321 with the movement of the chute block 320, the first connecting rod 380 can transmit this up and down movement to the first positioning plate 350 without deviation, ensuring the movement accuracy of the first positioning plate 350 in the vertical direction. Similarly, the second connecting rod 390 also plays the same role on the second positioning plate 360.

[0044] In summary, the use of the first connecting rod 380 and the second connecting rod 390 improves the motion transmission accuracy and reliability of the first positioning assembly 300. The use of the first connecting rod 380 and the second connecting rod 390 can effectively avoid the problem of inaccurate positioning caused by gaps or deviations during the transmission process, and ensure the synchronization and accuracy of the movement of the first positioning plate 350 and the second positioning plate 360 ​​in the vertical direction, which helps to improve the positioning accuracy of the entire rail transportation device.

[0045] like Figure 2 As shown, the track assembly 100 also includes a second positioning assembly 130, which includes a second driving device 131 and a positioning block 132. A boss 123 is provided on the side of the first assembly plate 121 close to the positioning block 132, and the positioning block 132 is provided with a notch, the shape of the notch matches the shape of the boss 123, and the second driving device 131 can drive the positioning block 132 to move toward the boss 123 so that the boss 123 is embedded in the notch to position the first assembly plate 121.

[0046] In a specific embodiment, the second positioning component 130 is a structure for assisting the positioning of the mounting base 120. The second driving device 131 is used as a power source and can be a motor, a cylinder, etc. In this embodiment, the second driving device 131 is a cylinder, the second driving device 131 is vertically arranged, and the second driving device 131 is fixedly assembled on the outside of the transport track 110. The positioning block 132 is fixedly assembled on the output end of the second driving device 131. A notch is provided on the side of the positioning block 132 close to the mounting base 120. A boss 123 is provided on the side of the first assembly plate 121 close to the second positioning component 130. The boss 123 is cylindrical, and the shape of the notch matches the shape of the boss 123. When the mounting base 120 moves to a preset position, the second driving device 131 drives the positioning block 132 to move toward the boss 123, so that the boss 123 is accurately embedded in the notch, thereby limiting the movement of the first assembly plate 121 at a specific position, further improving the positioning accuracy of the mounting base 120 on the transport track 110. This positioning method can be used in situations where the position of the mounting base 120 needs to be accurately stopped or adjusted, such as at specific workstations such as material loading and unloading and processing.

[0047] In summary, the addition of the second positioning component 130 further enhances the positioning function of the rail transport device. By working in coordination with the first positioning component 300, more accurate and reliable positioning can be achieved under different working stages and requirements. During material loading and unloading or processing, precise positioning can ensure the accuracy and efficiency of the operation, reduce problems such as material damage and processing errors caused by positioning errors, and improve product quality and production efficiency. At the same time, this dual positioning structure increases the positioning flexibility of the device, can be adjusted and optimized according to different production processes and material requirements, is suitable for a variety of complex production scenarios, and improves the versatility and adaptability of the equipment.

[0048] like Figure 2 As shown, the mounting base 120 further includes a plurality of rollers 124 . The rollers 124 are fixedly mounted on a side of the first assembly plate 121 away from the carrier assembly 200 , and the plurality of rollers 124 are clamped on both sides of the transport track 110 .

[0049] In a specific embodiment, the roller 124 is a key component for the mounting base 120 to slide on the transport track 110. A plurality of rollers 124 are fixed on one side of the first assembly plate 121 close to the transport track 110, and a plurality of rollers 124 are symmetrically clamped on both sides of the transport track 110. The outer surface of the roller 124 is in contact with the transport track 110, and the smooth movement of the mounting base 120 is achieved through the rolling friction between the roller 124 and the transport track 110.

[0050] In summary, the rolling of the rollers 124 makes the movement of the mounting base 120 on the transport track 110 more stable and smooth, reduces vibration and noise, and improves the reliability of the transport process. In addition, the structural design of the rollers 124 clamped on both sides of the transport track 110 can effectively prevent the mounting base 120 from derailing during transportation, thereby improving the safety of transportation.

[0051] like Figure 1 As shown, the transport track 110 is circular.

[0052] In a specific embodiment, the annular design of the transport track 110 enables the track transport device to realize a circular transport function. On an automated production line, materials can be continuously transported in a circular manner on the annular transport track 110, starting from a starting point, passing through various processing stations, testing stations, etc., and finally returning to the starting point or other designated locations, thereby realizing continuous circulation and automated processing of materials. This annular transport track 110 structure can make full use of space, improve the utilization rate of the production site, and can flexibly set the position and number of each station according to production requirements, facilitating the optimization and adjustment of the production process. A transmission belt is also provided on the inner side of the transport track 110, and the transmission belt is also annular. The shape of the transmission belt matches the shape of the transport track 110, and the mounting seat 120 is fixedly connected to the transmission belt, and the transmission belt is used to drive the mounting seat 120 to move on the annular track.

[0053] like Figure 2 As shown, the fixture plate 210 is provided with a lug 211 , and the positioning hole 212 is located on the lug 211 .

[0054] In a specific embodiment, the lug 211 is a portion protruding outward on the jig plate 210. The lugs 211 are symmetrically arranged on both sides of the jig plate 210. Each lug 211 is provided with a plurality of positioning holes 212. The design of the lug 211 can facilitate the docking of the positioning hole 212 with the positioning pin 361 in the first positioning assembly 300, and can also enhance the stability of the jig plate 210 during positioning. The position of the positioning hole 212 on the lug 211 is precisely calculated to ensure that when the first positioning plate 350 and the second positioning plate 360 ​​clamp the jig plate 210, the positioning pin 361 can be accurately inserted into the positioning hole 212. The design of the lug 211 makes the positioning of the jig plate 210 more accurate and reliable, and protects the main structure of the jig plate 210 to a certain extent, avoiding damage to the material on the jig plate 210 due to the positioning operation.
