Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to a multi-station carrier switching device. Background Art

[0002] With the progress of technology, people's demand for the quantity of products is constantly increasing. During the production and processing of a product, it often needs to go through multiple different processes. For each process, a corresponding device is usually required to perform specific actions on the product to be processed. After the actions are completed, the product is then transported to the next device for the next process. In order to reduce the time waste between two processes, a transportation device is often set between these devices to transport the product. An in-line flow line is thus generated. By transporting the product along the flow line to each station for processing in sequence, the production efficiency is ensured.

[0003] As the number of processes continues to increase, the corresponding number of devices also increases, and the space utilization rate has also become an issue that needs to be taken seriously.

Detailed implementation mode

[0043] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and be able to implement it, but the embodiments cited are not intended to limit the present invention.

[0044] The present invention discloses a multi-station vehicle switching device for switching the vehicle 10 among different stations, which includes a bottom plate 20. The bottom plate 20 includes a first direction D1 and a second direction D2 that are perpendicular to each other. Along the first direction D1 on the bottom plate 20, a first station S1, a second station S2, and a fifth station S5 are sequentially arranged. On one side of the second station S2 along the second direction D2, a third station S3 is arranged. On one side of the third station S3 along the first direction D1, a fourth station S4 is arranged; a first streamline 21 is arranged at the first station S1. The first streamline 21 includes a first displacement member 22, and the transportation direction of the first displacement member 22 is parallel to the first direction D1; a second streamline 23 is movably arranged on the second station S2 and the third station S3. The second streamline 23 includes a second displacement member 24, and the transportation direction of the second displacement member 24 is parallel to the first direction D1; a third streamline 25 is arranged at the fourth station S4. The third streamline 25 includes a third displacement member 26, and the transportation direction of the third displacement member 26 is parallel to the first direction D1; a fourth streamline 27 is arranged at the fifth station S5. The fourth streamline 27 includes a fourth displacement member 28, and the transportation direction of the fourth displacement member 28 is parallel to the first direction D1; each vehicle 10 sequentially passes through the first station S1, the second station S2, the third station S3, the fourth station S4, the third station S3, the second station S2, and the fifth station S5 to realize the processing of different processes.

[0045] Referring to Figure 1 and Figure 2 As shown, for the multi-station vehicle switching device of the present invention, the first streamline 21, the second streamline 23, the third streamline 25, and the fourth streamline 27 are all used for the transportation of the vehicle 10 to transport the vehicle 10 to the next station. Figure 1 Only for the understanding of the stations and directions, the specific structure is based on Figure 2subject to. Before transportation, the vehicle 10 can also be stopped and processed; it should be noted that whether each specific streamline directly transports the vehicle 10 to the next work station or stops and processes the vehicle 10 before transporting it to the next work station can be determined according to the processing requirements of the products on the actual vehicle 10. Each streamline realizes the transportation of the vehicle 10 through the corresponding displacement component; it should be noted that the first displacement component 22, the second displacement component 24, the third displacement component 26, and the fourth displacement component 28 can all adopt different structures to achieve transportation according to actual transportation requirements, such as the combined transportation of a synchronous pulley and a belt, the combined transportation of a lead screw, a motor, and a displacement block, etc., as long as the transportation of the vehicle 10 can be realized. The second streamline 23 can move between the second work station S2 and the third work station S3. According to different requirements, the driving mode of the second streamline 23 can be selected, such as through a motor cooperating with a lead screw, a synchronous pulley cooperating with a belt, a telescopic cylinder, etc. For the arrangement methods of different work stations, they can also be set according to actual requirements, not only including, for example, Figure 2 as shown in; for example, setting the third work station S3 on the other side of the second work station S2, setting the second work station S2 on the other side of the first work station S1, etc.

[0046] When the multi-station vehicle switching device of the present invention is in use, the vehicle 10 first enters the first streamline 21 to achieve loading, and then enters the second streamline 23 under the drive of the first displacement component 22. The second streamline 23 displaces along the second direction D2, displacing from the second work station S2 to the third work station S3, and the vehicle 10 enters the third streamline 25 under the drive of the second displacement component 24. Subsequently, the vehicle 10 returns to the second streamline 23 under the drive of the third displacement component 26; the second streamline 23 displaces along the second direction D2, displacing from the third work station S3 to the second work station S2. Finally, the vehicle 10 enters the fourth streamline 27 under the drive of the second displacement component 24 and realizes unloading under the drive of the fourth displacement component 28. The multi-station vehicle switching device of the present invention limits the positions of each streamline, shunts in the second direction D2, and reasonably utilizes space, making the structure of the entire device more compact and improving the space utilization rate. Setting the second streamline 23 to be able to move between the second work station S2 and the third work station S3 realizes the sharing of the same streamline by two work stations. Only four streamlines can meet the requirements of five work stations, reducing the cost of one streamline. On this basis, due to the improvement of space utilization rate and the reduction of the number of streamlines, when this device cooperates with other processing devices to process the products on the vehicle 10, more processing devices can be arranged to realize the processing of more processes. It also avoids the interference of the actions between different devices when other processing devices are processing.

[0047] Refer to Figure 3As shown, in some embodiments of the multi-station vehicle switching device of the present invention, both the second flow line 23 and the third flow line 25 include a lifting member 30 for lifting and positioning the vehicle 10. Considering the requirements for processing quality, the lifting member 30 is provided on the second flow line 23 and the third flow line 25. When processing is required, the lifting member 30 jacks up and positions the vehicle 10 to ensure that the products on the vehicle 10 can be precisely processed and the product quality is guaranteed. The lifting member 30 includes a separated state and a jacking and positioning state. When the lifting member 30 is in the separated state, the lifting member 30 is separated from the vehicle 10; when the lifting member 30 is in the jacking and positioning state, the lifting member 30 jacks up the vehicle 10 so that the vehicle 10 is separated from the second displacement member 24 or the third displacement member 26. When the vehicle 10 is being transported normally, the lifting member 30 is in the separated state and separated from the vehicle 10 to avoid interfering with the transportation of the vehicle 10; when a certain process of the vehicle 10 needs to be processed, the lifting member 30 rises to jack up the vehicle 10 and separates the vehicle 10 from the displacement member, thereby achieving positioning. It should be noted that different lifting members 30 can be selected according to different product requirements, such as cylinders, screw rods in cooperation with motors, etc., as long as the vehicle 10 can be jacked up and positioned. Considering that the first flow line 21 and the fourth flow line 27 are usually loading and unloading flow lines, and the position accuracy of the vehicle 10 on them is not as high as that of the vehicle 10 on the second flow line 23 and the third flow line 25, the lifting member 30 is only provided on the second flow line 23 and the third flow line 25 to achieve the jacking and positioning of the vehicle 10 at the second station S2, the third station S3, and the fourth station S4. Of course, the lifting member 30 can also be provided on the first flow line 21 and the fourth flow line 27 according to actual needs.

[0048] Further, referring to Figure 4 and 5As shown, in some embodiments of the multi-station vehicle switching device of the present invention, the second streamline 23 and the third streamline 25 both include two relatively arranged streamline support plates 40. The arrangement direction of the two streamline support plates 40 of the same streamline is parallel to the second direction D2, and the lifting member 30 is arranged between the two streamline support plates 40; the second displacement member 24 and the third displacement member 26 both include two sets of displacement units 29, and the two sets of displacement units 29 are respectively arranged on the two streamline support plates 40 of the same streamline. The displacement unit 29 is used to drive the vehicle 10 to displace along the first direction D1 and enter the second streamline 23 or enter the third streamline 25. In this part, the specific structures of the second streamline 23 and the third streamline 25 are defined. The second streamline 23 and the third streamline 25 both include two streamline support plates 40, and at least one set of displacement units 29 is arranged on each streamline support plate 40 to realize the transportation of the vehicle 10. This structure defines that the lifting member 30 is arranged between the streamline support plates 40 instead of on both sides, effectively improving the space utilization rate of the streamline itself. At the same time, for the limitation of the displacement unit 29, the two displacement units 29 cooperate to realize the transportation of the vehicle 10, avoiding the interference of the displacement unit 29 to the lifting member 30 during the lifting process of the lifting member 30. It should be noted that according to actual needs, the specific structure of the displacement unit 29 can be selected, such as a motor, a synchronous pulley cooperating with a synchronous belt, or a motor cooperating with a lead screw, as long as it can realize the transportation of the vehicle 10.

[0049] Further, referring to Figure 4 、 Figure 5 and Figure 14As shown, in some embodiments of the multi-station carrier switching device of the present invention, both the second streamline 23 and the third streamline 25 include at least two sets of opening and closing units 41. The opening and closing units 41 are respectively connected to the streamline support plates 40. Each streamline support plate 40 is provided with at least one set of the opening and closing units 41. The opening and closing units 41 are used to drive the two streamline support plates 40 of the second streamline 23 to approach or move away from each other relatively, or drive the two streamline support plates 40 of the third streamline 25 to approach or move away from each other relatively. By providing the opening and closing units 41 on the streamline support plates 40 of the second streamline 23 and the third streamline 25, the two streamline support plates 40 of the same streamline can be displaced relatively. This structural limitation effectively avoids the interference of the lifting component 30 on the carrier 10 and the displacement unit 29 during the lifting and positioning process. When jacking and positioning are required, the streamline support plates 40 can move away relatively; when processing is completed and positioning is not required, the streamline support plates 40 can move closer relatively, so that the carrier 10 can be placed on the displacement unit 29. Preferably, each set of the opening and closing units 41 includes an opening and closing fixed plate 411, an opening and closing cylinder 412, an opening and closing slider 413, and an opening and closing slide rail 414. The opening and closing fixed plate 411 is fixedly arranged, and the opening and closing cylinders 412 are respectively connected to the opening and closing fixed plate 411 and the streamline support plates 40; at the same time, the streamline support plates 40 are connected to the opening and closing sliders 413, and the opening and closing sliders 413 are slidably arranged on the opening and closing slide rails 414. The opening and closing slide rails 414 are fixedly arranged, and the opening and closing cylinders 412 expand and contract to realize the relative approach or separation of the streamline support plates 40. Preferably, an opening and closing buffer 416 is arranged on one axial side of the opening and closing slide rail 414 to avoid unnecessary losses caused by excessive displacement and reduce displacement collision; an opening and closing sensor 415 is arranged on the other axial side of the opening and closing slide rail 414 to detect the position of the streamline support plate 40.

[0050] Further, referring to Figure 4 、 Figure 5 and Figure 14As shown, in some embodiments of the multi-station carrier switching device of the present invention, the second streamline 23 includes two sets of the second displacement components 24, and the two sets of the second displacement components 24 are arranged in sequence along the height direction of the streamline support plate 40; the third streamline 25 includes two sets of the third displacement components 26, and the two sets of the third displacement components 26 are arranged in sequence along the height direction of the streamline support plate 40. Among them, when the lifting component 30 displaces the carrier 10 from the upper second displacement component 24 to the lower second displacement component 24, or when the lifting component 30 displaces the carrier 10 from the lower second displacement component 24 to the upper second displacement component 24, the opening and closing unit 41 drives the two streamline support plates 40 of the second streamline 23 to first move away from each other and then move closer to each other; when the lifting component 30 displaces the carrier 10 from the upper third displacement component 26 to the lower third displacement component 26, or when the lifting component 30 displaces the carrier 10 from the lower third displacement component 26 to the upper third displacement component 26, the opening and closing unit 41 drives the two streamline support plates 40 of the second streamline 23 to first move away from each other and then move closer to each other. Through the arrangement of the two sets of displacement components, the second streamline 23 and the third streamline 25 can improve the production efficiency on the premise of ensuring the space utilization rate, enabling the carrier 10 to quickly achieve reflux and not interfering with the processing of the next carrier 10. It can be imagined that on the premise that the streamline support plate 40 cooperates with the opening and closing unit 41 to be able to open and close, the carrier 10 on the upper third displacement component 26 of the third streamline 25 can descend to the lower third displacement component 26, and then be transported to the lower second displacement component 24 through the lower third displacement component 26, and then the carrier 10 can be lifted from the lower second displacement component 24 to the upper second displacement component 24 through the lifting component 30. At the same time, the next carrier 10 is transported from the upper second displacement component 24 to the upper third displacement component 26, achieving the effect of rapid switching of the carriers 10 on the second streamline 23 and the third streamline 25 and ensuring the production efficiency. In addition, in cooperation with the structure of the lifting component 30, the opening and closing unit 41 and the two sets of displacement components, compared with additionally arranging a transfer structure outside the streamline to realize the switching of the upper and lower displacement components, this structure can well ensure the overall space utilization rate, does not occupy extra space, so that the saved space can be used for the setting of other processing devices, which can improve the overall integration degree; and it can also avoid the mutual interference between different processing devices. In the prior art, in addition to the linear streamline, there is also a streamline structure that rotates through a turntable. It is provided with a turntable, and different processing devices are arranged around the turntable, and the products are transported to different devices in sequence by rotating the turntable to realize the processing of different processes. This turntable-type streamline can undoubtedly improve the space utilization rate compared with the linear streamline. However, when actually carrying out processing production, the disadvantages of this structure are then discovered.When transporting and processing products with small volume and light weight, the rotary streamline can work well. However, when facing products with slightly larger volume and slightly heavier weight, the products have a certain rotational inertia, and it is impossible to ensure that the products can be accurately rotated and transported to the appropriate position for processing. If positioning components are additionally arranged on the turntable to position the products, the energy consumption during rotation will increase. Moreover, when the processing devices arranged around the turntable are in operation, due to the small relative distance between different processing devices and the easy occurrence of mutual interference, it is not suitable for the whole-line automated online production and processing. And this device well overcomes the above defects, can ensure the production efficiency and space utilization rate, and realizes the efficient and precise automated processing of products. It should be noted that in the above, when the opening and closing unit 41 drives the two streamline support plates 40 to first move away from each other and then move closer to each other, the first and second time nodes can be set according to actual needs, as long as the interference between the lifting component 30, the carrier 10 and the displacement unit 29 is avoided. For example, after the carrier 10 arrives and before the lifting component 30 contacts the carrier 10, the opening and closing unit 41 immediately drives them away; or when the carrier 10 is lifted by the lifting unit by a certain distance and positioned, the opening and closing unit 41 immediately drives them away. Similarly, after the carrier 10 is lifted above the displacement unit 29 by a certain distance by the lifting component 30, the opening and closing unit 41 drives them closer, and then the lifting component 30 descends so that the carrier 10 contacts the displacement unit 29; it is also possible that after the lifting component 30 directly lifts the carrier 10 to a height parallel to the surface of the displacement unit 29 where the carrier 10 contacts, the opening and closing unit 41 drives them closer.

[0051] Further, referring to Figure 6As shown, in some embodiments of the multi-station carrier switching device of the present invention, the lifting member 30 includes a jacking plate 31, a first lifting unit 32, and a second lifting unit 33. The jacking plate 31, the first lifting unit 32, and the second lifting unit 33 are connected and arranged in sequence from top to bottom. Both the first lifting unit 32 and the second lifting unit 33 include an extended state and a retracted state. By setting two lifting units to cooperate with the jacking plate 31 to achieve the jacking and positioning of the carrier 10, the jacking efficiency and jacking accuracy can be well guaranteed, ensuring that the carrier 10 can quickly and accurately switch between two sets of displacement members. Preferably, two cylinders are selected as the first lifting unit 32 and the second lifting unit 33, and the pistons of the two cylinders are connected. The jacking plate 31 is also connected to a guide rod 34, and the guide rod 34 can move up and down relative to the guide base 36, and the guide base 36 is fixedly arranged; to ensure stability during the lifting process and prevent deflection and jitter. Preferably, a buffer pad 35 is further provided at the end of the guide rod 34 away from the jacking plate 31 to achieve buffering between the guide rod 34 and the guide base 36. When both the first lifting unit 32 and the second lifting unit 33 are in the retracted state, the jacking plate 31 is located below the second displacement member 24 or the third displacement member 26 at the lower layer and is separated from the carrier 10; when the first lifting unit 32 is in the extended state and the second lifting unit 33 is in the retracted state, the jacking plate 31 jacks up the carrier 10 on the second displacement member 24 at the lower layer or the carrier 10 on the third displacement member 26, so that the carrier 10 is separated from the second displacement member 24 or the third displacement member 26 at the lower layer; when both the first lifting unit 32 and the second lifting unit 33 are in the extended state, the carrier 10 on the second displacement member 24 at the upper layer or the carrier 10 on the third displacement member 26 is jacked up, so that the carrier 10 is separated from the second displacement member 24 or the third displacement member 26 at the upper layer; when the first lifting unit 32 is in the retracted state and the second lifting unit 33 is in the extended state, the jacking plate 31 is located below the second displacement member 24 or the third displacement member 26 at the upper layer and is separated from the carrier 10. Taking the second flow line 23 as an example for illustration, when the carrier 10 arrives, refer to Figure 8 As shown, at this time, both the first lifting unit 32 and the second lifting unit 33 are in the retracted state, the jacking plate 31 is separated from the carrier 10, and the carrier 10 stays on the second displacement member 24 at the lower layer. Then, as Figure 9 shown, the first lifting unit 32 is in the extended state and jacks up the jacking plate 31, so that the jacking plate 31 separates the carrier 10 from the second displacement member 24 at the lower layer. Subsequently, as Figure 10As shown, the opening and closing unit 41 drives the streamline support plate 40 to move relatively away to avoid interfering with the ascent of the vehicle 10. After the streamline support plate 40 moves away, as Figure 11 shown, the first lifting component 30 jacks up and is in the extended state to jack up the vehicle 10 above the second displacement component 24 on the upper layer. As Figure 12 shown, after the jacking is in place, the opening and closing unit 41 drives the streamline support plate 40 to move relatively closer. Finally, as Figure 13 shown, the first lifting unit 32 is in the retracted state, so that the jacking plate 31 is separated from the vehicle 10, and thus the vehicle 10 falls onto the second displacement component 24 on the upper layer, completing the switching of the vehicle 10 from the lower layer to the upper layer. Other jacking processes are similar and will not be repeated.

[0052] Furthermore, referring to Figure 6 and Figure 7 shown, in some embodiments of the multi-station vehicle switching device of the present invention, at least two positioning pins 311 are provided on the surface of the lifting component 30 in contact with the vehicle 10, and positioning holes 11 adapted to the positioning pins 311 are provided on the vehicle 10. By providing the positioning pins 311 and cooperating with the positioning holes 11, the positioning of the vehicle 10 can be well achieved, avoiding problems such as random shaking of the vehicle 10 and ensuring the processing accuracy of the product. Preferably, a hollow part 312 is provided on the jacking plate 31, which can not only reduce the weight and reduce the jacking energy consumption, but also increase the structural strength of the jacking plate 31.

[0053] Furthermore, referring to Figure 14 shown, in some embodiments of the multi-station vehicle switching device of the present invention, the second streamline 23 further includes a blocking member 241, and the blocking member 241 is provided at the end of the second displacement component 24 on the lower layer. By providing the blocking member 241, it can be avoided that when the vehicle 10 is displaced from the third displacement component 26 on the lower layer to the second displacement component 24 on the lower layer, over-displacement occurs. Preferably, the blocking member 241 is provided as two fixedly arranged blocking plates, which have a simple structure and effectively play a blocking role. Of course, other blocking members 241 can also be selected according to actual needs as long as they can achieve blocking.

[0054] Furthermore, referring to Figure 2 and Figures 15 - 22As shown, in some embodiments, the multi-station carrier switching device of the present invention further includes a displacement base plate 50 and a displacement driving member 51. The second streamline 23 is disposed on the displacement base plate 50, and the displacement driving member 51 drives the displacement base plate 50 to move between the second station S2 and the third station S3. This structure defines the structure for the second streamline 23 to move between the second station S2 and the third station S3. The second streamline 23 realizes the displacement between the two stations through the displacement floor and the displacement driving member 51. According to actual requirements, different displacement driving members 51 can be selected, such as a motor cooperating with a lead screw, a cylinder, etc. Preferably, a motor and a synchronous cooperation with a rack are selected to achieve displacement; at the same time, a guide rail is provided to ensure accuracy. Preferably, components such as the opening and closing unit 41 and the lifting member 30 are all disposed on the displacement base plate 50. This structure can accurately realize the movement of the second streamline 23 between the second station S2 and the third station S3. Among them, when the carrier 10 enters the upper third displacement member 26 from the upper second displacement member 24, the displacement driving member 51 drives the displacement base plate 50 to return to the second station S2 and pick up the next carrier 10; when the carrier 10 enters the lower second displacement member 24 from the lower third displacement member 26, the displacement driving member 51 drives the displacement base plate 50 to return to the second station S2; during the return process, the opening and closing unit 41 drives the two streamline support plates 40 of the second streamline 23 to first move away from each other and then move closer to each other, so that the lifting plate 31 lifts the carrier 10 on the lower second displacement member 24 to the upper second displacement member 24. Through this limitation, the second streamline 23 can make full use of the idle time of the carrier 10 on the third streamline 25 during processing to transport the subsequent carrier 10 or cooperate with other devices for processing. It ensures the overall production efficiency and can carry and process more carriers 10. It should be noted that the time nodes of first and then in the first move away from each other and then move closer to each other here are the same as those above, as long as the mutual interference of components during the lifting process can be avoided, and no repeated description will be made.

[0055] Refer to Figure 23As shown, in some embodiments of the multi-station carrier switching device of the present invention, positioning members 60 are provided on the first displacement member 22, the second displacement member 24, the third displacement member 26, and the fourth displacement member 28. The positioning member 60 is used for blocking and positioning the carrier 10. The positioning member 60 includes a passing state and a blocking and positioning state. When the positioning member 60 is in the passing state, the carrier 10 can be displaced along the first direction D1. When the positioning member 60 is in the blocking and positioning state, the positioning member 60 blocks the carrier 10 from being displaced along the first direction D1. By providing the positioning member 60, positioning of the carrier 10 for each streamline is achieved, facilitating processing by other devices. Preferably, the positioning member 60 includes a positioning column 61, a positioning slider 62, a positioning slide rail 63, and a positioning cylinder 64. The positioning cylinder 64 and the positioning slide rail 63 are both fixedly provided. The two ends of the positioning slider 62 are respectively connected to the positioning column 61 and the piston of the positioning cylinder 64. At the same time, the positioning slider 62 is movably arranged on the positioning slide rail 63 to achieve precise and stable blocking and positioning of the carrier 10. Preferably, a detection sensor is also provided to detect whether the carrier 10 is in place, facilitating the state switching of the positioning member 60.

[0056] The working principle of the multi-station carrier switching device of the present invention is as follows:

[0057] Referring to Figure 15 As shown, first, a carrier 10 enters the first streamline 21. On the first streamline 21, this carrier 10 can choose whether other devices are needed for processing according to actual requirements. Secondly, as Figure 16 shown, the first carrier 10 enters the second streamline 23 located at the second station S2. At this time, the second carrier 10 enters the first streamline 21. On the second streamline 23 at the second station S2, the first carrier 10 can choose whether other devices are needed for processing according to actual requirements. When processing is required, both the first lifting unit 32 and the second lifting unit 33 are in the extended state, so that the lifting plate 31 separates the carrier 10 from the displacement unit 29 to achieve positioning and facilitate precise processing. Subsequently, as Figure 17 shown, the second streamline 23 is displaced to the third station S3 under the drive of the displacement driving member 51. On the second streamline 23 at the third station S3, the first carrier 10 can choose whether other devices are needed for processing according to actual requirements. Then, as Figure 18 shown, the first carrier 10 is displaced onto the upper third displacement member 26 of the third streamline 25. Here, the first carrier 10 can choose whether other devices are needed for processing according to actual requirements. At the same time, during this idle time, the second streamline 23 returns to the second station S2 to pick up the second carrier 10. As Figure 19As shown, the first carrier 10 is lowered to the third displacement component 26 of the lower layer under the cooperation of the lifting component 30 and the opening and closing unit 41; at the same time, the second streamline 23 transports the second carrier 10 to the third workstation S3. Figure 20 As shown, under the action of the displacement unit 29, the second carrier 10 is transported from the second displacement component 24 of the upper layer to the third displacement component 26 of the upper layer; at the same time, the first carrier 10 is transported from the third displacement component 26 of the lower layer to the second displacement component 24 of the lower layer. Figure 21 As shown, the second streamline 23 completes the lifting of the first carrier 10 from the second displacement component 24 of the lower layer to the second displacement component 24 of the upper layer during the process of returning to the second workstation S2; at the same time, the second carrier 10 also descends from the third displacement component 26 of the upper layer to the third displacement component 26 of the lower layer. Figure 22 As shown, the first carrier 10 is transported to the fourth flow line 27 under the action of the displacement unit 29. On the fourth flow line 27, the first carrier 10 can choose whether to need other devices for processing or unloading according to actual needs; at the same time, the second flow line 23 also receives the next carrier 10 to repeat the process. Figures 19 to 22 Corresponding steps are performed to achieve continuous processing and transportation of the products on the carrier 10.

[0058] The device limits the position of each streamline, diverts in the second direction D2, and reasonably utilizes the space, so that the structure of the entire device is more compact and the space utilization rate is improved. The second streamline 23 is set to be able to move between the second station S2 and the third station S3, so that two stations share the same streamline. Only four streamlines can meet the needs of five stations, reducing the cost of one streamline. On this basis, due to the improvement of space utilization and the reduction in the number of streamlines, when the device cooperates with other processing devices to realize the processing of products on the carrier 10, it is possible to arrange more processing devices and realize the processing of more processes. It also avoids interference between the actions of different devices when other processing devices are processing. The setting of the lifting component 30 and the opening and closing unit 41 makes the entire processing flow more efficient and further ensures high space utilization.

[0059] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
