Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.

The invention discloses a multi-station carrier switching device, which is used for switching carriers 10 at different stations and comprises a bottom plate 20, wherein the bottom plate 20 comprises a first direction D1 and a second direction D2 which are perpendicular to each other, a first station S1, a second station S2 and a fifth station S5 are sequentially arranged on the bottom plate 20 along the first direction D1, a third station S3 is arranged on one side of the second station S2 along the second direction D2, and a fourth station S4 is arranged on one side of the third station S3 along the first direction D1; a first streamline 21, the first streamline 21 is disposed at the first station S1, the first streamline 21 includes a first displacement member 22, and a transport direction of the first displacement member 22 is parallel to the first direction D1; a second flow line 23, the second flow line 23 being movably disposed at the second station S2 and the third station S3, the second flow line 23 including a second displacement member 24, the transport direction of the second displacement member 24 being parallel to the first direction D1; a third flow line 25, the third flow line 25 being disposed at the fourth station S4, the third flow line 25 including a third displacement member 26, the transport direction of the third displacement member 26 being parallel to the first direction D1; a fourth flow line 27, the fourth flow line 27 being disposed at the fifth station S5, the fourth flow line 27 including a fourth displacement member 28, the transport direction of the fourth displacement member 28 being parallel to the first direction D1; each carrier 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 processing in different working procedures.

Referring to fig. 1 and 2, the multi-station carrier switching device according to the present invention includes a first flow line 21, a second flow line 23, a third flow line 25 and a fourth flow line 27 for transporting the carrier 10 to the next station. Fig. 1 is only used for understanding the station and the direction, and the specific structure is based on fig. 2. Before transportation, the carrier 10 can be stopped and the carrier 10 can be processed; it should be noted that, specifically, whether each streamline directly conveys the carrier 10 to the next station, or conveys the carrier 10 to the next station after stopping and processing, it can be determined according to the processing requirement of the product on the actual carrier 10. Each streamline realizes the transportation of the carrier 10 through the corresponding displacement component; the first displacement member 22, the second displacement member 24, the third displacement member 26, and the fourth displacement member 28 can all be transported by different structures according to actual transportation requirements, such as combined transportation of a synchronous wheel and a belt, combined transportation of a screw, a motor, and a displacement block, and the like, so long as transportation of the carrier 10 can be achieved. The second flow line 23 can move between the second station S2 and the third station S3, and according to different requirements, a driving mode of the second flow line 23 can be selected, for example, a motor is matched with a screw rod, a synchronous wheel is matched with a belt, a telescopic cylinder is matched with the belt, and the like. The arrangement modes of different stations can also be set according to actual requirements, and the arrangement modes of the different stations do not only comprise one type shown in fig. 2; for example, the third station S3 is provided on the other side of the second station S2, the second station S2 is provided on the other side of the first station S1, etc.

In the multi-station carrier switching device, when in use, the carrier 10 firstly enters the first flow line 21 to realize feeding, and then enters the second flow line 23 under the drive of the first displacement component 22. The second flow line 23 is displaced along the second direction D2, and is displaced from the second station S2 to the third station S3, and the carrier 10 enters the third flow line 25 under the drive of the second displacement member 24. Subsequently, the carrier 10 is returned to the second flow line 23 by the third displacement member 26; the second streamline 23 is displaced in the second direction D2 from the third station S3 to the second station S2. Finally, the carrier 10 enters the fourth flow line 27 under the drive of the second displacement component 24, and realizes blanking under the drive of the fourth displacement component 28. The multi-station carrier switching device limits the positions of all the streamline, and the space is divided in the second direction D2 to reasonably utilize the space, so that the whole device has a more compact structure and the space utilization rate is improved. The second streamline 23 can be moved between the second station S2 and the third station S3, the same streamline is shared by double stations, the requirements of five stations can be met by only four streamlines, and the cost of one streamline is reduced. On this basis, because space utilization improves, streamline quantity reduces for this device is when cooperating other processingequipment to realize the processing to the product on the carrier 10, can arrange more processingequipment, realize the processing of more multiple operation. And interference of actions among different devices when other processing devices are used for processing is avoided.

Referring to fig. 3, in the multi-station carrier switching device according to the present invention, in some embodiments, the second flow line 23 and the third flow line 25 each include a lifting member 30, and the lifting member 30 is used for lifting and positioning the carrier 10. In consideration of the requirement on the processing quality, the lifting component 30 is arranged on the second flow line 23 and the third flow line 25, and when processing is required, the lifting component 30 lifts and positions the carrier 10, so that the products on the carrier 10 can be accurately processed, and the product quality is ensured. The lifting component 30 comprises a separation state and a lifting positioning state, and when the lifting component 30 is in the separation state, the lifting component 30 is separated from the carrier 10; when the lifting member 30 is in the lifting positioning state, the lifting member 30 lifts the carrier 10 such that the carrier 10 is separated from the second displacement member 24 or the third displacement member 26. When the carrier 10 is normally transported, the lifting component 30 is separated from the carrier 10 in a separation state, so that the carrier 10 is prevented from being disturbed in transportation; when the carrier 10 needs to be processed in a certain process, the lifting member 30 is lifted up to lift up the carrier 10, and the carrier 10 is separated from the displacement member, thereby realizing positioning. It should be noted that, according to different product requirements, different lifting components 30, such as a cylinder, a screw rod, and a motor, can be selected, so long as the lifting and positioning of the carrier 10 can be achieved. Considering that the first flow line 21 and the fourth flow line 27 are usually feeding and discharging flow lines, for the position accuracy of the carriers 10 thereon, the carriers 10 on the second flow line 23 and the third flow line 25 are not high, and therefore, the lifting members 30 are only arranged on the second flow line 23 and the third flow line 25 to realize the lifting positioning of the carriers 10 at the second station S2, the third station S3 and the fourth station S4. Of course, the lifting member 30 may be provided to the first flow line 21 and the fourth flow line 27 according to actual needs.

Further, referring to fig. 4 and 5, in the multi-station carrier switching device according to the present invention, in some embodiments, each of the second streamline 23 and the third streamline 25 includes two streamline support plates 40 disposed opposite to each other, the alignment 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 disposed between the two streamline support plates 40; the second displacement member 24 and the third displacement member 26 each include two groups of displacement units 29, where the two groups of displacement units 29 are respectively disposed on two streamline support plates 40 of the same streamline, and the displacement units 29 are used to drive the carrier 10 to displace along the first direction D1 and enter the second streamline 23 or the third streamline 25. In this section, a specific structure of the second flow line 23 and the third flow line 25 is defined, and each of the second flow line 23 and the third flow line 25 includes two flow line support plates 40, and at least one group of displacement units 29 are disposed on each of the flow line support plates 40 to realize transportation of the carrier 10. This structure defines the elevating member 30 to be disposed between the streamline support plates 40 instead of both sides, effectively improving the space utilization of the streamline itself. Meanwhile, for limiting the displacement units 29, the two displacement units 29 are matched to realize the transportation of the carrier 10, so that the interference of the displacement units 29 on the lifting component 30 in the lifting process of the lifting component 30 is avoided. It should be noted that, according to actual needs, a specific structure of the displacement unit 29, such as a motor, a synchronous wheel, a synchronous belt, or a motor, a screw rod, etc., may be selected, so long as the transportation of the carrier 10 can be achieved.

Further, referring to fig. 4, 5 and 14, in some embodiments of the multi-station carrier switching device according to the present invention, each of the second streamline 23 and the third streamline 25 includes 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 at least provided with one set of opening and closing units 41, and the opening and closing units 41 are used for driving two streamline support plates 40 of the second streamline 23 to relatively approach or separate, or driving two streamline support plates 40 of the third streamline 25 to relatively approach or separate. By providing the opening and closing unit 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 relatively displaced. The limitation of the structure effectively avoids the interference of the lifting component 30 to the carrier 10 and the displacement unit 29 in the lifting and positioning process. The streamline support plate 40 can be relatively far away when jacking positioning is required; upon completion of the machining, without positioning, the streamline support plate 40 can be relatively close so that the carrier 10 can be placed on the displacement unit 29. Preferably, each group of the opening and closing units 41 includes an opening and closing fixing plate 411, an opening and closing cylinder 412, an opening and closing slider 413 and an opening and closing sliding rail 414. The opening and closing fixing plate 411 is fixedly arranged, and the opening and closing cylinder 412 is respectively connected with the opening and closing fixing plate 411 and the streamline support plate 40; meanwhile, the streamline support plate 40 is connected with the opening and closing sliding block 413, the opening and closing sliding block 413 can be arranged on the opening and closing sliding rail 414 in a sliding mode, the opening and closing sliding rail 414 is fixedly arranged, and the opening and closing air cylinder 412 stretches out and draws back to achieve relative approaching or separating of the streamline support plate 40. Preferably, an opening and closing buffer element 416 is arranged on one axial side of the opening and closing sliding rail 414, so as to avoid over-displacement and reduce unnecessary loss caused by displacement collision; the other axial side of the opening and closing slide rail 414 is provided with an opening and closing sensor 415 to detect the position of the streamline support plate 40.

Further, referring to fig. 4, 5 and 14, in the multi-station carrier switching device according to the present invention, in some embodiments, the second flow line 23 includes two sets of the second displacement members 24, and the two sets of the second displacement members 24 are sequentially arranged along the height direction of the flow line support plate 40; the third flow line 25 includes two sets of the third displacement members 26, and the two sets of the third displacement members 26 are sequentially disposed along the height direction of the flow line support plate 40. Wherein, when the lifting member 30 moves the carrier 10 from the second moving member 24 at the upper layer to the second moving member 24 at the lower layer, or when the lifting member 30 moves the carrier 10 from the second moving member 24 at the lower layer to the second moving member 24 at the upper layer, the opening and closing unit 41 drives the two streamline support plates 40 of the second streamline 23 to be relatively far away and then relatively close; the opening and closing unit 41 drives the two streamline support plates 40 of the second streamline 23 to be relatively far apart and then relatively close when the lifting member 30 displaces the carrier 10 from the third displacement member 26 of the upper layer to the third displacement member 26 of the lower layer, or when the lifting member 30 displaces the carrier 10 from the third displacement member 26 of the lower layer to the third displacement member 26 of the upper layer. Through the arrangement of the two groups of displacement components, the second flow line 23 and the third flow line 25 can improve the production efficiency on the premise of ensuring the space utilization rate, so that the carrier 10 can quickly realize backflow without interfering with the processing of the next carrier 10. It is conceivable that the carrier 10 of the third displacement member 26 located at the upper layer of the third flow line 25 is lowered onto the third displacement member 26 at the lower layer on the premise that the flow line support plate 40 is openable and closable by the opening and closing unit 41, and then transported to the second displacement member 24 at the lower layer by the third displacement member 26 at the lower layer, and then the carrier 10 is lifted up to the second displacement member 24 at the upper layer from the second displacement member 24 at the lower layer by the lifting member 30. Meanwhile, the next carrier 10 is transported to the third displacement component 26 on the upper layer from the second displacement component 24 on the upper layer, so that the effect of rapidly switching the carriers 10 of the second flow line 23 and the third flow line 25 is realized, and the production efficiency is ensured. In addition, in cooperation with the structures of the lifting member 30, the opening and closing unit 41 and the two groups of displacement members, compared with the structure that a transfer structure is additionally arranged outside a streamline to realize the switching of the upper and lower displacement members, the structure can well ensure the whole space utilization rate and does not occupy extra space, so that the saved spaces are used for the arrangement of other processing devices, and the whole integration degree can be improved; mutual interference between different processing devices can be avoided. In the prior art, besides a straight streamline, a streamline structure which rotates through a turntable is also arranged, a turntable is arranged around the turntable, different processing devices are arranged, and products are sequentially transported to different equipment through the turntable to realize processing of different procedures. The turntable streamline can certainly improve the space utilization rate compared with a straight streamline. However, the disadvantages of this structure are found in the actual production of the process. The turntable streamline can work well when facing small-volume and light-weight products for transportation and processing. However, when the product with a slightly larger volume and a slightly heavier weight is faced, the product has a certain rotational inertia, and the product cannot be guaranteed to be accurately transported to a proper position for processing. If the product is positioned by additionally providing a positioning member on the turntable, the power consumption upon rotation increases. Moreover, when the processing device arranged around the turntable is used for processing, the relative distance between different processing devices is small, mutual interference is easy to occur, and the processing device is not suitable for the whole-line automatic online production and processing. The device well overcomes the defects, can ensure the production efficiency and the space utilization rate, and realizes the efficient and accurate automatic processing of products. It should be noted that, the above opening and closing unit 41 drives the two streamline support plates 40 to be relatively far away from each other and then relatively close to each other, and the first and second time nodes can be set according to actual requirements, so long as interference among the lifting member 30, the carrier 10 and the displacement unit 29 is avoided. For example, when the carrier 10 is in place and before the lifting member 30 contacts the carrier 10, the opening and closing unit 41 is driven away; or when the carrier 10 is lifted by the lifting unit for a certain distance to realize positioning, the opening and closing unit 41 is driven to move away. Similarly, when the carrier 10 is lifted by the lifting member 30 to a distance above the displacement unit 29, the opening and closing unit 41 is driven to approach, and the lifting member 30 descends again to make the carrier 10 contact with the displacement unit 29; the opening/closing unit 41 may be driven to approach after the carrier 10 is directly lifted up to a height parallel to the surface of the displacement unit 29 contacting the carrier 10 by the lifting member 30.

Further, referring to fig. 6, in some embodiments of the multi-station carrier switching device according to the present invention, the lifting member 30 includes a lifting plate 31, a first lifting unit 32 and a second lifting unit 33, the lifting plate 31, the first lifting unit 32 and the second lifting unit 33 are sequentially connected from top to bottom, and the first lifting unit 32 and the second lifting unit 33 each include an extended state and a retracted state. By arranging two lifting units to be matched with the lifting plate 31, lifting positioning of the carrier 10 is realized, lifting efficiency and lifting precision can be well guaranteed, and switching between two groups of displacement components of the carrier 10 can be rapidly and accurately realized. Preferably, two cylinders are selected as the first elevating unit 32 and the second elevating unit 33, and pistons of the two cylinders are connected. The jacking plate 31 is also connected with a guide rod 34, the guide rod 34 can move up and down relative to a guide base 36, and the guide base 36 is fixedly arranged; so as to ensure stability and no deflection and jitter in the lifting process. Preferably, the end of the guide rod 34 remote from the jacking plate 31 is also provided with a cushioning pad 35 to provide cushioning with the guide base 36.

The working principle of the multi-station carrier switching device provided by the invention is as follows:

referring to fig. 15, first, a piece of carrier 10 enters a first flow line 21. On the first flow line 21, the piece of carrier 10 can select whether other devices are needed for processing according to actual requirements. Next, as shown in fig. 16, the first block carrier 10 enters the second flow line 23 at the second station S2, and at this time, the second block carrier 10 enters the first flow line 21. On the second streamline 23 of the second station S2, the first carrier 10 can select whether other devices are needed for processing according to actual requirements; when processing is required, the first lifting unit 32 and the second lifting unit 33 are both in an extended state, so that the lifting plate 31 separates the carrier 10 from the displacement unit 29, thereby realizing positioning and facilitating accurate processing. Subsequently, as shown in fig. 17, the second streamline 23 is displaced to the third station S3 by the displacement driving member 51, and the first block carrier 10 can select whether other devices are required for processing according to actual requirements on the second streamline 23 of the third station S3. Next, as shown in fig. 18, the first carrier 10 is displaced onto the upper third displacement member 26 of the third flow line 25, where the first carrier 10 can select whether other devices are required for processing according to actual requirements; at the same time, the second flow line 23 returns to the second station S2 during the spare time to pick up the second block carrier 10. As shown in fig. 19, the first carriage 10 is lowered onto the third displacement member 26 of the lower stage by the elevating member 30 and the opening/closing unit 41; while the second flow line 23 transports the second chunk carrier 10 to the third station S3. As shown in fig. 20, the second block carrier 10 is transported by the second displacement member 24 of the upper layer to the third displacement member 26 of the upper layer by the displacement unit 29; at the same time, the first block carrier 10 is transported from the third displacement member 26 of the lower layer to the second displacement member 24 of the lower layer. As shown in fig. 21, the second streamline 23 completes the lifting of the first block carriers 10 from the second displacement member 24 of the lower layer to the second displacement member 24 of the upper layer in the process of returning to the second station S2; at the same time, the second mass carrier 10 is also lowered from the third displacement member 26 of the upper layer onto the third displacement member 26 of the lower layer. Finally, as shown in fig. 22, the first block carrier 10 is transported to the fourth flow line 27 under the action of the displacement unit 29, and on the fourth flow line 27, the first block carrier 10 can select whether other devices are needed for processing or blanking according to actual requirements; at the same time, the second flow line 23 also receives and removes a piece of carrier 10, so as to repeat the steps corresponding to fig. 19 to 22, and realize continuous processing and transportation of the product on the carrier 10.
