Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of inhaul cable precision motion modules, and in particular to a drag chain device and an inhaul cable module. Background Art
[0002] As the scale of inhaul cable PMM (precision motion modules) increases, the number of hot-press forming modules continues to rise, leading to a significant increase in the overall size of the equipment. Against this background, the length of the drag chain matched with the transfer module is also extended to ten meters or even more than ten meters.
[0003] However, the ultra-long drag chain is prone to sagging and deformation under the action of its own weight during the reciprocating movement, resulting in unintended friction between the upper and lower layers of the drag chain. This friction will not only aggravate the wear on the surface of the drag chain and reduce its service life, but also may cause problems such as operating noise and jamming, affecting equipment stability and production efficiency. Contents of the Utility Model
[0004] In view of this, the utility model provides a drag chain device to solve the problems of drag chain wear, low service life, high operating noise and jamming.
[0005] In a first aspect, the present application provides a drag chain device, comprising a drag chain, a first support portion and a second support portion. The drag chain is adapted to move along a first direction; the first support portion is arranged on the drag chain, the first support portion comprises a connecting member and a rolling member arranged on the connecting member, and the connecting member is connected with the drag chain, so that the first support portion follows the drag chain to move along the first direction; the second support portion is arranged on the moving path of the first support portion; wherein when the drag chain moves along the first direction, the upper surface of the second support portion is used for supporting the rolling member.
[0006] Beneficial effects: Through the combined supporting effect of the first support portion and the second support portion on the drag chain, the upper layer of the drag chain is supported to maintain a distance from the lower layer of the drag chain during movement, avoiding mutual friction of the drag chains, which can not only prolong the service life of the drag chain, but also avoid problems such as operating noise and jamming, and improve equipment stability and production efficiency.
[0007] In an optional implementation, the rolling member comprises a roller and a roller outer cover, the roller outer cover is connected with the connecting member, the roller is arranged at the bottom of the roller outer cover, and the roller is rollably arranged on the second support portion.
[0008] Beneficial effects: By arranging the roller on the second support portion in a rollable manner, the frictional resistance between the rolling member and the second support portion is reduced, thereby reducing the noise generated during the movement of the drag chain and facilitating the movement of the drag chain. At the same time, the form of the roller matched with the roller outer cover can simplify the overall structure of the rolling member, and is more adapted to the movement direction of the drag chain while providing supporting force.
[0009] In one optional embodiment, the roller cover includes a box-shaped cover and a spindle disposed inside the box-shaped cover. The bottom of the box-shaped cover is provided with an opening. The roller is rotatably disposed on the spindle. The bottom of the roller protrudes from the opening. The connector is connected to the upper part of the box-shaped cover.
[0010] Beneficial effects: By setting up a box-shaped outer cover and a spindle, the roller is housed in the box-shaped outer cover to protect it. At the same time, the setting of the spindle facilitates the rotation of the roller relative to the box-shaped outer cover, which in turn facilitates the rolling of the roller relative to the second support.
[0011] In one alternative embodiment, a cleaning portion is provided on at least one side of the rolling element, and the cleaning portion contacts the upper surface of the second support portion.
[0012] Beneficial effects: By setting a cleaning part on the rolling element, when the rolling element moves on the upper surface of the second support, the cleaning part can follow the roller and clean the dust on the upper surface of the second support, keeping the upper surface of the second support clean and facilitating the movement of the rolling element on the second support.
[0013] In one alternative embodiment, the cleaning unit includes a brush and a mounting member, the brush being mounted to the box-shaped outer cover via the mounting member, and the bottom of the brush contacting the second support portion.
[0014] Beneficial effects: The brush is mounted on the box-shaped outer cover by the mounting parts, and the movement of the rolling parts makes it easy for the brush to adhere to and clean the dust on the second support.
[0015] In one alternative embodiment, the second support is a support rail, the upper surface of which has two inclined surfaces and a horizontal plane disposed between the two inclined surfaces, the height of the upper surface of the inclined surfaces gradually increasing in the direction of the inclined surfaces toward the horizontal plane.
[0016] Beneficial effects: The second support section adopts a support rail configuration, which facilitates its arrangement. Furthermore, inclined planes are provided at both ends of the support rail, and a horizontal plane is positioned between the two inclined planes. The horizontal plane supports the rolling elements, effectively maintaining a distance between the upper and lower cable chains during movement. Additionally, when the first support section leaves the support range of the support rail, the inclined planes cushion the impact, reducing damage from collisions.
[0017] In one alternative embodiment, the top surface of the support track is provided with a collection hole; the lower part of the support track is provided with a collection component corresponding to the collection hole.
[0018] Beneficial effects: By setting collection holes on the support track and setting collection components for the corresponding collection holes, when the cleaning part cleans the surface of the first support part, the dust can quickly leave the support track through the collection holes, thereby achieving rapid cleaning of the support track. In addition, the collection components facilitate the collection and centralized treatment of dust.
[0019] In one alternative embodiment, the cable chain is provided with a plurality of connectors and a plurality of rolling elements at intervals along the first direction, with each connector being disposed on a respective rolling element.
[0020] Beneficial effects: Setting up multiple connectors to support the cable chain makes it less prone to sagging and deformation during the reciprocating movement of ultra-long cable chains, thus improving the support effect on the cable chain.
[0021] In one alternative embodiment, an elastic element is provided between the connector and the rolling element.
[0022] Beneficial effects: By incorporating elastic elements, the vibration transmitted from the rolling elements to the cable chain can be reduced when the cable chain drives the rolling elements, thereby improving the stability of the cable chain.
[0023] Secondly, this application provides a pull-wire module, including: a transplanting module guide rail and a transplanting gripper, wherein the transplanting gripper is movably disposed on the transplanting module guide rail; a drag chain device as described in any one of the above is provided on one side of the transplanting module guide rail, the transplanting gripper is disposed on the drag chain, the drag chain is disposed between the transplanting module guide rail and the second support portion, the drag chain is provided with at least one first support portion, and the drag chain is connected to the connector.
[0024] Beneficial effects: This cable pulling module features the aforementioned cable chain device. Through the combined support of the first and second support parts, the upper cable chain is supported and kept at a distance from the lower cable chain during movement, preventing friction between them. During operation, this avoids problems such as operating noise and jamming, improving equipment stability and production efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0029] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.
[0030] In a first aspect, this application provides a cable chain device, including a cable chain 1, a first support portion 2, and a second support portion 3. The cable chain 1 is adapted to move along a first direction X. The first support portion 2 is disposed on the cable chain 1 and includes a connector 21 and a rolling element 22 disposed on the connector 21. The connector 21 is connected to the cable chain 1 so that the first support portion 2 moves with the cable chain 1 along the first direction X. The second support portion 3 is disposed on the moving path of the first support portion 2. When the cable chain 1 moves along the first direction X, the upper surface of the second support portion 3 is used to support the rolling element 22.
[0031] First, it should be noted that in this embodiment, the first direction X is the direction of movement of the cable chain 1. In this embodiment, "upper part," "lower part," "upper layer," and "lower layer" refer to positions along the height direction of the cable chain device; that is, the upper part is located above the lower part along the height direction, and the upper layer is located above the lower layer along the height direction. The cable chain 1 includes an upper cable chain 1 and a lower cable chain 1. During the reciprocating movement of the extra-long cable chain 1, the upper cable chain 1 is prone to sagging and deformation due to its own weight, causing unexpected friction between the upper and lower cable chains 1. This exacerbates the wear on the surfaces of the upper and lower cable chains 1 and can also lead to problems such as operating noise and jamming.
[0032] In this embodiment, as Figure 1 , Figure 5 As shown, the first support part 2 is used to support the upper cable chain 1. The connector 21 can be a connecting plate or a connecting frame. One end of the connector 21 is connected and fixed to the cable chain 1, and the other end of the connector 21 is connected to the rolling element 22. The connector 21 can be connected to the upper part of the upper cable chain 1, or to the lower part of the upper cable chain 1. Of course, the connector 21 can also be connected to the side of the upper cable chain 1. The following description uses the connection of the connector 21 to the lower part of the upper cable chain 1 as an example.
[0033] The rolling element 22 is disposed at the lower part of the connecting element 21 and is movably disposed on the second support part 3. The structure of the second support part 3 can be set according to the size of the on-site installation space. Since this application is for supporting the cable chain 1, which is connected to the transplanting gripper 200, the movement of the cable chain 1 is a reciprocating linear motion. Therefore, the movement direction of the rolling element 22 connected to the cable chain 1 through the connecting element 21 is also a linear reciprocating motion. The structure of the second support part 3 can be set as a linear type to adapt to the movement direction of the rolling element 22. The second support part 3 is disposed on one side of the cable chain 1, and the rolling element 22 connected to the cable chain 1 through the connecting element 21 is also located on one side of the cable chain 1 to avoid interference with the cable chain 1. The second support part 3 and the first support part 2 only serve to support the cable chain 1.
[0034] With this configuration, the first support part 2 and the second support part 3 jointly support the cable chain 1, so that the upper cable chain 1 is supported and kept at a distance from the lower cable chain 1 when it moves, avoiding contact between the upper cable chain 1 and the lower cable chain 1 and mutual friction. This not only improves the service life of the cable chain 1, but also avoids problems such as operating noise and jamming, thereby improving equipment stability and production efficiency.
[0035] Optionally, in the first support portion 2 described above, one or more connecting members 21 may be provided on each rolling element 22. Preferably, one connecting member 21 is provided on each rolling element 22 so that the rolling element 22 can effectively support the connecting member 21, while simplifying the structure of the first support portion 2.
[0036] In one embodiment, the rolling element 22 includes a roller 221 and a roller cover 222. The roller cover 222 is connected to the connector 21. The roller 221 is disposed at the bottom of the roller cover 222 and is rotatably disposed on the second support 3.
[0037] In this embodiment, as Figure 5 As shown, the roller cover 222 is connected to the connector 21, and the connector 21 can be installed on the upper part of the roller cover 222, which facilitates the connection between the connector 21 and the upper cable chain 1. Furthermore, the connector 21 can be installed on the top surface of the roller cover 222. This not only facilitates the connection between the connector 21 and the roller cover 222, but also facilitates the arrangement of the elastic element 6 between the top surface of the roller cover 222 and the connector 21, thereby achieving the technical effect of reducing vibration transmitted from the rolling element 22 to the connector 21.
[0038] The roller cover 222 is used to mount the roller 221, and the rolling direction of the roller 221 is consistent with the movement direction of the cable chain 1. When the cable chain 1 is moving, it drives the roller 221 to roll on the second support 3 through the connector 21 and the roller cover 222 in sequence. In this way, by rotatably mounting the roller 221 on the second support 3, the rolling friction between the roller 221 and the second support 3 can be reduced, which not only facilitates the movement of the roller 221 on the second support 3 by the cable chain 1, but also reduces the noise generated by the cable chain 1 during movement. At the same time, the use of roller 221 in conjunction with roller cover 222 simplifies the overall structure of the rolling element 22, and makes it more compatible with the movement direction of the cable chain 1 while providing support.
[0039] In one embodiment, the roller cover 222 includes a box-shaped cover 2221 and a spindle 2222 disposed inside the box-shaped cover 2221. The bottom of the box-shaped cover 2221 is provided with an opening. The roller 221 is rotatably disposed on the spindle 2222. The bottom of the roller 221 protrudes from the opening. The connector 21 is connected to the upper part of the box-shaped cover 2221.
[0040] In this embodiment, as Figure 5 , Figure 6 , Figure 7 As shown, the box-shaped outer cover 2221 includes five walls, including four side walls and one top wall. Two opposing side walls are used to mount and fix the mandrel 2222, and the top wall is used to connect with the connector 21. The five walls and the opening form an open cuboid structure. The axis of the mandrel 2222 is perpendicular to the direction of movement of the roller 221. The bottom of the roller 221 protrudes from an opening, and the height of the protrusion can be adjusted according to the actual application. By setting the box-shaped outer cover 2221 and the mandrel 2222 together, the roller 221 is housed within the box-shaped outer cover 2221, providing protection for the roller 221. Simultaneously, the mandrel 2222 facilitates the rotation of the roller 221 relative to the box-shaped outer cover 2221, thereby facilitating the rolling of the roller 221 relative to the second support 3.
[0041] Alternatively, in addition to the five-wall arrangement described above, the box-shaped outer cover 2221 may also include three walls, namely two opposing side walls and a top wall, wherein the two opposing side walls are used to mount and fix the mandrel 2222. In this way, while ensuring the mandrel 2222 is effectively mounted on the box-shaped outer cover 2221, the material of the box-shaped outer cover 2221 is reduced, thereby lowering production costs.
[0042] In one embodiment, since the dust generated during the use of the cable chain device is easy to fall onto the upper surface of the second support 3, and the roller 221 generates dust by rubbing against the upper surface of the second support 3 when it moves, the presence of dust affects the movement of the roller 221. A cleaning part 4 is provided on at least one side of the rolling element 22, and the cleaning part 4 contacts the upper surface of the second support 3.
[0043] In this embodiment, as Figure 4 , Figure 5 As shown, when the rolling element 22 includes a box-shaped outer cover 2221, the cleaning part 4 can be fixed to the outer wall of the box-shaped outer cover 2221. Specifically, along the moving direction of the rolling element 22, the cleaning part 4 can be fixed to one side of the box-shaped outer cover 2221 or to both sides of the box-shaped outer cover 2221. When two cleaning parts 4 are provided, the arrangement direction of the two cleaning parts 4 is consistent with the moving direction of the roller 221.
[0044] In this way, by providing a cleaning part 4 on the rolling element 22, when the roller 221 moves on the upper surface of the second support 3, the cleaning part 4 can follow the roller 221 and clean the dust on the upper surface of the second support 3, so that the upper surface of the second support 3 is kept clean and the roller 221 can move on the second support 3.
[0045] In one embodiment, the cleaning part 4 includes a brush 41 and a mounting member 42. The brush 41 is mounted on the box-shaped outer cover 2221 via the mounting member 42, and the bottom of the brush 41 contacts the second support part 3.
[0046] In this embodiment, as Figure 5 As shown, by contacting the upper surface of the second support 3 with the brush 41, the brush 41 can effectively remove dust from the upper surface of the second support 3 as it moves with the roller 221. The mounting member 42 can be a strip plate or a fixing frame arranged along the box-shaped outer cover 2221, and the brush 41 can be arranged along the length direction of the mounting member 42, that is, the length direction of the brush 41 is perpendicular to the movement direction of the roller 221.
[0047] Optionally, the mounting component 42 can be detachably connected to the box-shaped outer cover 2221 by means of bolting, bonding or snapping, thereby facilitating the replacement of the brush 41.
[0048] In one embodiment, the second support 3 is a support rail, the upper surface of which has two inclined surfaces 31 and a horizontal surface 33 disposed between the two inclined surfaces 31. The height of the upper surface of the inclined surfaces 31 gradually increases in the direction of the inclined surfaces 31 toward the horizontal surface 33.
[0049] In this embodiment, as Figure 1 , Figure 2 , Figure 4 As shown, the extension direction of the support track is consistent with the movement direction of the cable chain 1. On the upper surface of the support track, inclined surfaces 31 are provided at both ends, and a horizontal surface 33 is provided between the two inclined surfaces 31. When the cable chain 1 drives the first support part 2 to move beyond the length of the top surface of the support track, after the first support part 2 leaves the support range of the support track, its height will be lower than the height of the top surface of the support track under the influence of gravity. By providing inclined surfaces 31 at both ends of the support track, the rollers 221 of the first support part 2 can be cushioned after leaving the top surface of the support track, and before they move to the top surface of the support track, thereby reducing damage to the rollers 221 and other structures of the first support part 2 due to impacts.
[0050] In one embodiment, a collection hole 32 is provided on the top surface of the support track; a collection member 5 corresponding to the collection hole 32 is provided on the lower part of the support track.
[0051] In this embodiment, as Figure 3 , Figure 4 As shown, several collection holes 32 are arranged along the top surface of the support track and are evenly distributed on the top surface of the support track. When the brush 41 moves in contact with the top surface of the support track, the dust on the top surface of the support track will be driven to fall down along the collection holes 32, so that the dust can quickly leave the support track through the collection holes 32, thereby realizing the rapid cleaning of the support track.
[0052] Optionally, to facilitate the collection of dust falling from the collection holes 32, the collection component 5 includes a collection box 51 and a collection pipe 52. The upper opening of the collection box 51 covers the area of all the collection holes 32 distributed on the support track to improve the collection effect. The bottom of the collection box 51 is provided with several funnel-shaped collection ports, each of which is connected to the collection pipe 52 to achieve centralized collection of dust. Of course, in addition to the above-described configuration, the collection component 5 can also adopt other structures capable of collecting dust.
[0053] In one embodiment, in order to improve the support effect on the cable chain 1, the cable chain 1 is provided with a plurality of connectors 21 and a plurality of rolling elements 22 at intervals along the first direction X, and each connector 21 is respectively disposed on each rolling element 22.
[0054] In this embodiment, as Figure 1 As shown, multiple connectors 21 are spaced apart along the movement direction of the cable chain 1, and each connector 21 can be supported by a rolling element 22. Thus, when dealing with a long cable chain 1, the cable chain 1 can be supported by adding connectors 21, making it less prone to sagging and deformation during reciprocating movement of the extra-long cable chain 1, thereby improving the support effect on the cable chain 1. Furthermore, within the maximum stroke of the cable chain 1, preferably each first support part 2 can be supported by a second support part 3, further enhancing the support effect of the first support part 2 on the cable chain 1.
[0055] The number of the aforementioned connectors 21 can be adjusted adaptively according to the specific length of the cable chain 1.
[0056] In one embodiment, when the drag chain 1 drives the rolling element 22 to move, a large vibration feedback will be generated. In order to reduce the vibration between the connector 21 and the rolling element 22, an elastic element 6 is provided between the connector 21 and the rolling element 22.
[0057] In this embodiment, as Figure 5 , Figure 6 , Figure 7As shown, the connector 21 can be mounted on the top surface of the box-shaped outer cover 2221 via the mounting plate 7, and an elastic element 6 is provided between the box-shaped outer cover 2221 and the connector 21. The elastic element 6 can reduce the vibration transmitted from the rolling element 22 to the cable chain 1, thereby improving stability.
[0058] Optionally, the elastic element 6 can be a spring, and the number of springs can be set according to the actual application. When the elastic element 6 is set as a spring, the spring can be used in conjunction with a damper (not shown in the figure) to achieve the shock absorption function. Of course, the elastic element 6 can also be a flexible pad or other material that can achieve the shock absorption function.
[0059] Secondly, this application provides a pull-wire module, including: a transplanting module guide rail 100 and a transplanting gripper 200, the transplanting gripper 200 being movably disposed on the transplanting module guide rail 100; a drag chain device of any of the above is disposed on one side of the transplanting module guide rail 100, the transplanting gripper 200 is disposed on the drag chain 1, the drag chain 1 is disposed between the transplanting module guide rail 100 and the second support part 3, the drag chain 1 is provided with at least one first support part 2, and the drag chain 1 is connected to the connector 21.
[0060] In this embodiment, as Figure 1 , Figure 2 As shown, the cable pulling module has the aforementioned cable carrier device. The first support part 2 and the second support part 3 jointly support the cable carrier 1, ensuring that the upper cable carrier 1 is supported and maintains a distance from the lower cable carrier 1 during movement, thus preventing friction between the cable carriers. During the operation of the cable pulling module, this avoids problems such as operating noise and jamming, improving equipment stability and production efficiency.
