Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and in particular to a cable chain. Background Technology

[0002] Cable chains are widely used in various automated equipment, including semiconductor equipment, to protect cables (such as power cables and hoses) from bending and tangling. Furthermore, when used in cleanroom semiconductor equipment, cable chains can also prevent dust generation caused by friction between different cables.

[0003] Since cable chains travel long distances alongside devices such as robotic arms, it is crucial to ensure the support strength of the sections of the cable chain that follow these devices to prevent collapse. In related technologies, one solution involves providing mutually abutting bosses in the middle of the main body of a corrugated cable chain in a second direction. The support provided by these bosses helps prevent collapse. In this method, the bosses are essentially formed by making the thickness of the middle section of the main body of the cable chain in the second direction greater than the thickness of the sides in the second direction. Furthermore, adjacent bosses are closely spaced along the first direction of the cable chain. Therefore, the process of forming these bosses requires sophisticated manufacturing techniques.

[0036] Figure 1 This is a schematic diagram of the cable chain according to the first aspect of this utility model. Figure 2 yes Figure 1 An enlarged view of point a in the middle. Figure 3 This is a simplified schematic diagram of support member 200. Figure 4 This is a side view of the cable chain according to an embodiment of this application. Figure 5 This is an exploded view of the cable chain according to an embodiment of this application. Figure 5 Only a portion of the cable chain is shown. (See reference) Figures 1 to 5According to a first aspect embodiment of the present invention, a cable chain for storing strip-shaped objects (not shown in the figures) includes a main body 100 and a plurality of support members 200. The main body 100 can be bent along its first direction to form a straight section 140 (dotted line frame portion) and a curved section 150 (dashed line frame portion). The main body 100 has a storage portion 110 and an extension portion 120. The storage portion 110 extends along the first direction of the main body 100 (the length direction of the main body 100 in the figures), and the strip-shaped object is stored in the storage portion 110. The extension portion 120 is located at least on one side of the main body 100 in a second direction orthogonal to the first direction (the width direction of the main body 100 in the figures). The extension portion 120 is connected to the storage portion 110 and extends along the first direction of the main body 100 together with the storage portion 110, while extending relative to the storage portion 110 toward the side of the main body 100 in the second direction. Multiple support members 200 are arranged on the extension 120 along the first direction of the main body 100, and when the multiple support members 200 are arranged in the straight section 140 of the main body 100, two adjacent support members 200 along the first direction of the main body 100 abut against each other along the first direction.

[0037] In this embodiment, the extension 120 has a simple shape and is easy to process and form. Compared with the previous method of forming a support structure on the outer surface of the corrugated portion 101 of the main body 100, setting the support member 200 on the extension 120 can reduce the production difficulty while providing support force.

[0038] It should be noted that although the dashed box portion is used to represent the curved segment 150 and the dotted line portion is used to represent the straight segment 140, this is only for illustrative purposes. The curved segment 150 and the straight segment 140 change with the movement of the cable chain. Furthermore, in this application, the first direction, second direction, and third direction of the main body 100 also change with the bending of the cable chain. Therefore, the first direction, second direction, and third direction will be different at different positions, but at the same position, the first direction, second direction, and third direction are always perpendicular.

[0039] Understandably, in the straight section 140, each support member 200 provides support by mutually resisting each other along the first direction. Under the short-stroke condition of the cable chain, the potential collapse problem of the upper straight section 140 is effectively reduced. Therefore, under the short-stroke condition, no other support means are needed (for example, the keel assembly 500 can be omitted), providing more space for the arrangement of strips (cables, air pipes, etc.), reducing the overall volume of the main body 100, or further optimizing the spatial configuration of the strips to accommodate the selection of more production components.

[0040] In this context, cable chain lengths of 1500mm or less are considered short-stroke, while cable chain strokes greater than 1500mm are considered long-stroke. (Refer to...) Figure 5 In long-stroke conditions, in addition to the support component 200, a keel assembly 500 can also be configured. The support component 200 and the keel assembly 500 work together to provide support, which can reduce the collapse problem that may occur in the cable chain under long stroke.

[0041] Specifically, the main body 100 can be made of flexible materials such as rubber, polyvinyl chloride, and polyurethane to achieve bending and wear resistance. The support 200 can be made of the same material as the main body 100. The support 200 is integrally formed with the main body 100 during the molding process.

[0042] Figure 6 This is an explosion diagram of the main body 100. Figure 7 This is an explosion diagram of the main body 100 from another perspective. (See reference...) Figure 6 and Figure 7 The main body 100 may have an extension 120 on one side in the second direction, or it may have extensions 120 on both sides in the second direction to accommodate more support members 200 and provide greater support strength. The specific design can be adapted to meet the support requirements.

[0043] Reference Figure 2 In some embodiments, each support member 200 is disposed on the outer side of the extension 120 in a third direction, wherein the third direction is a direction orthogonal to both the first and second directions. The shape of the receiving portion 110 of the main body 100 can be set to an elliptical shape to minimize the space occupied in the third direction while accommodating the strip as much as possible. Therefore, the dimension in the second direction is larger than the dimension in the third direction. Connecting the support member 200 to the third-direction side of the main body 100 allows for a larger contact area for connection, ensuring the connection strength between the support member 200 and the extension 120, and facilitating processing and shaping. On the other hand, the support member 200 can also be placed closer to the main body 100 to ensure that the application of supporting force counteracts the weight of the strip and reduces collapse.

[0044] Reference Figure 1 and Figure 4 In the curved section 150, since the bending process creates an inner and outer diameter, if the support member 200 is located on the inner diameter of the curved section 150, the bending process requires overcoming a large force, and may even result in the inability to bend. Furthermore, the support member 200 is prone to damage under excessive pressure. Conversely, if the support member 200 is only installed in the relevant area of ​​the straight section 140, the support force provided by the support member 200 is limited, affecting the support effect.

[0045] Therefore, in some embodiments, the main body 100 has opposing straight sections 140 in a third direction, a curved section 150 connects the opposing straight sections 140, and an extension 120 is provided with support members 200 on the opposite side (outer diameter side) of the opposing straight sections 140, and at least a portion of the plurality of support members 200 extends into the curved section 150. By positioning the support members 200 on the opposite side of the opposing straight sections 140, when a portion of the support members 200 bends from the straight section 140 into the curved section 150, they separate from each other and lose their support due to being at the outer diameter of the bend, which is beneficial for the bending of the cable chain. The plurality of support members 200 can also be evenly arranged on the extension 120 along the first direction of the main body 100 for ease of processing.

[0046] In this embodiment, support members 200 can also be provided on the side of the relatively straight sections 140 that are close to each other (the side of the inner diameter) to further provide support, as long as the support members 200 on the side that are close to each other do not extend into the curved section 150. It is understood that during operation, after the main body 100 is bent, there are always relatively straight sections 140 on both sides of it in the first direction. Therefore, the actual length that the curved section 150 may cover on the main body 100 is limited. As long as support members 200 are provided in the part that may form the curved section 150, it can be ensured that the inner diameter at the curved section 150 will not have support members 200 that hinder bending.

[0047] Reference Figure 2 and Figure 3 In some embodiments, the support member 200 includes a connecting portion 210 and a supporting portion 220. The connecting portion 210 connects the extension portion 120 and the supporting portion 220. The supporting portion 220 abuts against the supporting portion 220 of the adjacent support member 200. The connecting portion 210 has a dimension D1 in a first direction of the main body 100, and the supporting portion 220 has a dimension D2 in the first direction of the main body 100, satisfying that D1 < D2. The size setting of the connecting portion 210 and the supporting portion 220 allows the support member 200 to present a T-shape that is wider at the top and narrower at the bottom. The connecting portion 210 has a smaller size, which can reduce the consumption of production materials. When the supporting portions 220 abut against each other, they can more easily swing slightly with the movement of the cable chain. When the support member 200 moves into the bending section 150, the bending resistance can also be reduced, making the movement smoother.

[0048] Reference Figures 5 to 7In some embodiments, the main body 100 includes a first housing 160 and a second housing 170. The first housing 160 and the second housing 170 each include a receiving portion 110 and an extension portion 120. The extension portion 120 of the first housing 160 and the extension portion 120 of the second housing 170 are connected along a third direction of the main body 100. A receiving cavity 130 for receiving strip-shaped objects is formed between the receiving portion 110 of the first housing 160 and the receiving portion 110 of the second housing 170. Dividing the main body 100 into the first housing 160 and the second housing 170 allows for the laying of cables or other strip-shaped objects on one housing before the other housing is attached and connected. This simplifies assembly compared to the action of threading cables or other strip-shaped objects into the receiving cavity 130. The first housing 160 and the second housing 170 can be mutually fixed using bolts / screws, pressure plates / strips, grooves / slots, welding, riveting, or other methods.

[0049] Specifically, in some embodiments, one of the extensions 120 of the first housing 160 and the second housing 170 is provided with a locking groove 180, and the other is provided with a locking boss 190. The locking groove 180 and the locking boss 190 are both located on opposite sides of the first housing 160 and the second housing 170, and the locking boss 190 engages within the locking groove 180. The engagement of the locking boss 190 and the locking groove 180 enables a detachable connection between the first housing 160 and the second housing 170, facilitating assembly and disassembly. Specifically, the locking boss 190 and the locking groove 180 can be configured as a dovetail block and a dovetail groove, respectively, so that the size of the locking boss 190 inside the locking groove 180 is larger than the opening of the locking groove 180, thereby improving the connection strength between the two.

[0050] Figure 8 This is a simplified schematic diagram showing the connecting component 300 in the engaged state. (Refer to...) Figures 6 to 8 In some embodiments, based on the main body 100 including a first housing 160 and a second housing 170, the cable chain further includes a connecting assembly 300. The connecting assembly 300 is located on one side of the main body 100 in a second direction. The connecting assembly 300 includes a first connector 310 and a second connector 320. The first connector 310 is connected to the extension 120 of the first housing 160, and the second connector 320 is connected to the extension 120 of the second housing 170. The first connector 310 and the second connector 320 are alternately arranged in a first direction of the main body 100, and the first connector 310 and the second connector 320 are detachably connected. The connection assembly 300 can improve the connection strength between the first housing 160 and the second housing 170, and compared with the direct pressing and bonding of the first housing 160 and the second housing 170, it can also achieve a detachable connection.

[0051] Reference Figure 6 and Figure 7 In some embodiments, the connecting component 300, the engaging boss 190, and the engaging groove 180 can be simultaneously provided to jointly achieve a detachable connection between the first housing 160 and the second housing 170. The connecting component 300 is located on one side of the main body 100 in a second direction. The connecting component 300 includes a detachably connected first connector 310 and a second connector 320. The first connector 310 is connected to the extension 120 of the first housing 160, and the second connector 320 is connected to the extension 120 of the second housing 170. The first connector 310 and the second connector 320 are alternately arranged in the first direction of the main body 100. In the second direction of the main body 100, the support member 200, the engaging boss 190, and the engaging groove 180 are located between the connecting component 300 and the receiving portion 110. The connecting component 300 is located on the outermost side of the extension 120 in the second direction of the main body 100 to achieve sealing and connection on the outside. The engaging boss 190 and engaging groove 180 further connect the first housing 160 and the second housing 170. The support member 200 can also be positioned as close as possible to the storage part 110 to ensure support.

[0052] Specifically, refer to Figure 2 and Figure 8 In some embodiments, the first connector 310 includes a first engagement portion 311 and a first limiting portion 312. The first engagement portion 311 connects the first limiting portion 312 and the extension 120 of the first housing 160. The first limiting portion 312 is located on the side of the first engagement portion 311 facing the second housing 170. The second connector 320 includes a second engagement portion 321 and a second limiting portion 322. The second engagement portion 321 connects the second limiting portion 322 and the extension 120 of the second housing 170. The second limiting portion 322 is located on the side of the second engagement portion 321 facing the first housing 160, and the second limiting portion 322 is located on the side of the first limiting portion 312 facing the first engagement portion 311. The first limiting portion 312 and the second limiting portion 322 abut against each other in the third direction of the main body 100. By abutting against each other, the movement of the first housing 160 and the second housing 170 separating from each other in the third direction of the main body 100 can be restricted, thereby improving the connection strength.

[0053] Reference Figure 8In some embodiments, a first guide surface 313 is provided on the side of the first limiting part 312 opposite to the first joining part 311. The first guide surface 313 is inclined in a third direction of the main body 100 and is used to abut against the second limiting part 322. When assembling the first housing 160 and the second housing 170, the first limiting part 312 and the second limiting part 322 need to be fastened along a third direction of the main body 100 so that the first limiting part 312 and the second limiting part 322 are ultimately in a mutually abutting and fastened state. The provision of the first guide surface 313 can guide the first limiting part 312 and the second limiting part 322 relative to the direction of movement during movement, so as to drive the first limiting part 312 and the second limiting part 322 to deform and avoid positioning, reducing the assembly difficulty.

[0054] Reference Figure 8 In other embodiments, a second guide surface 323 is provided on the side of the second limiting portion 322 opposite to the second joining portion 321. The second guide surface 323 is inclined to a third direction of the main body 100 and is used to abut against the first limiting portion 312. Similarly, the provision of the second guide surface 323 can also guide the movement direction of the first limiting portion 312 and the second limiting portion 322, thereby reducing the assembly difficulty. The first guide surface 313 and the second guide surface 323 can be provided simultaneously to further improve the guiding effect.

[0055] Figure 10 This is a schematic diagram of connector 400, please refer to it. Figure 9 and Figure 10 In some embodiments, the cable chain further includes a connector 400, which has a first compression groove 410 extending along a first direction of the main body 100. At least a portion of the connecting component 300 is housed in the first compression groove 410. The first compression groove 410 has a communicating first entry section 411 and a first engagement section 412. The groove diameter of the first entry section 411 gradually decreases in the direction approaching the first engagement section 412. The connector 400 enables the rapid installation of the first connector 310 and the second connector 320. The first connector 310 and the second connector 320 enter the first entry section 411 together. The gradually decreasing groove diameter of the first entry section 411 compresses the first connector 310 and the second connector 320, causing them to gradually approach and deform against each other. After the first connector 310 and the second connector 320 pass through the first engagement section 412, the installation is completed.

[0056] Reference Figure 10In other embodiments, the connector 400 is further provided with a second pressing groove 420, which has a communicating second entry section 421 and a second engagement section 422. The groove diameter of the second entry section 421 gradually decreases along the direction close to the second engagement section 422, wherein the groove diameter of the first engagement section 412 is larger than that of the second engagement section 422. The function and installation principle of the second pressing groove 420 are the same as those of the first pressing groove 410, but the groove diameter of the second engagement section 422 is smaller than that of the first engagement section 412, which can further increase the pressing force on the first connector 310 and the second connector 320. In actual installation, the first pressing groove 410 or the second pressing groove 420 can be selected to install the connecting assembly 300 according to the working conditions and requirements, so as to adjust the engagement amount of the first connector 310 and the second connector 320.

[0057] The following describes the specific assembly and movement process of the cable chain in some embodiments:

[0058] First, the strip is placed on the first housing 160, and then the second housing 170 is closed onto the first housing 160. Pressing the first housing 160 and the second housing 170 together causes the engaging protrusions 190 and engaging grooves 180 to engage one-to-one. Then, the connector 400 is used to press and connect the first connecting member 310 and the second connecting member 320, so that the first connecting member 310 and the second connecting member 320 are in a mutually engaged state. The connector 400 can be detached after completing the connection function, or it can be left directly on the connecting assembly 300 to facilitate adjustment of the engagement degree of the connecting assembly 300.

[0059] Furthermore, the cable chain also includes a fixed connector 600. The main body 100 has fixed connectors 600 connected to both ends in the first direction. The fixed connectors 600 have high rigidity, ensuring the connection between the cable chain and the external drive equipment. When the keel assembly 500 needs to be installed in long-stroke conditions, a fastener 610 is also provided inside the fixed connector 600. The fastener 610 is fixed to the fixed connector 600 by snap-fitting, welding, or other methods, and is connected to the keel assembly 500 to fix the position of the keel assembly 500 within the main body 100. A protruding structure 620 is also provided on the side of the fixed connector 600 opposite to the main body 100. The protruding structure 620 provides an installation position for cable ties and other fixing equipment, facilitating the fixing of cables and other strip-shaped objects to the fixed connector 600.

[0060] During short-stroke operation, the support members 200 located in the straight section 140 abut against each other, providing support for the main body 100 of the straight section 140 and reducing the possibility of collapse or downward tilting of the upper straight section 140. As the movement progresses, part of the original straight section 140 will bend into a curved section 150. Since the support members 200 are located on the outside of the bend, the outer diameter of the bend separates the support members 200 from each other, thus not affecting the bending action, resulting in smooth movement.

[0061] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
