Description

Technical Field

[0001] This utility model relates to the field of hanging fixture technology, and discloses a buffer device for a flat-top chain in conjunction with a hanging fixture roller and an electroplating equipment production line. Background Technology

[0002] Existing hanger buffer devices typically employ a structure combining a belt and teeth. A motor drives the belt, causing the teeth to move with the belt, which in turn propels the hanger forward, thus achieving hanger transport. However, the belt is prone to slippage and wear during operation, and the positioning accuracy during the engagement of the hanger and teeth is poor, resulting in rigid collisions between the teeth and the hanger, leading to numerous potential failure points and frequent maintenance. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a buffer device and electroplating equipment production line with a flat-top chain and a hanging roller, which effectively solves the problem of high failure rate of the buffer device.

[0004] In a first aspect, this utility model provides a buffer device for a flat-top chain in conjunction with a hanging roller, comprising:

[0005] Installation main body;

[0006] A drive motor is connected to the side of the mounting body and located at one end of the mounting body. The output shaft of the drive motor is rotatably connected to a drive wheel.

[0007] A flat-topped chain is fitted onto the outer surface of the drive wheel;

[0008] The hanger has rolling components on both sides, which abut against the upper surface of the flat-top chain and roll freely on the upper surface of the flat-top chain.

[0009] Beneficial Effects: The drive motor is mounted on the outside of the mounting body, and its output shaft is rotatably connected to the drive wheel. The flat-top chain is fitted onto the drive wheel and circulates under its drive. The flat surface of the flat-top chain provides stable support and a rolling surface for the rolling components of the hanger. The hanger is used to carry materials to be conveyed or temporarily stored. Multiple rolling components are provided on both sides of the hanger. These components abut against the upper surface of the flat-top chain and can roll freely on it. During the operation of the drive motor, the motor provides driving force to rotate the output shaft, which then transmits the driving force to the drive wheel. The drive wheel then transmits the driving force to the flat-top chain fitted onto its outer surface, thus driving the chain to move. The upper surface of the flat-top chain generates a horizontal frictional force on the rolling components, thereby driving the rolling components to move and causing the entire hanger to move synchronously with the chain. In this invention, the flat-top chain is more wear-resistant than the belt; by setting rolling components on both sides of the hanger, the rolling components abut against the upper surface of the flat-top chain, allowing the rolling components to roll freely relative to the flat-top chain, thus placing the hanger directly above the flat-top chain without needing to engage the hanger with the teeth, which can effectively reduce the failure rate of the buffer device and thus reduce the maintenance frequency.

[0010] In one embodiment, the rolling assembly includes a support column and a roller, the support column being fixedly connected to both sides of the hanger, and the roller being rotatably fitted onto the support column and abutting against the upper surface of the flat-top chain.

[0011] In one embodiment, a limiting structure is also included, which is installed on both sides of the mounting body to restrict the left and right movement of the hanger.

[0012] In one embodiment, the limiting structure includes a first connector, a second connector, and a limiting rod. One end of the first connector is connected to the mounting body, and the other end extends out of the upper surface of the flat-top chain. The second connector is connected to the second connector and extends above the flat-top chain. The limiting rod is connected to the second connector.

[0013] In one embodiment, a blocking structure is also included, mounted on the mounting body, for restricting the movement of the hanger.

[0014] In one embodiment, the blocking structure includes a driving member and a blocking member, the blocking member being drive-connected to the driving member, and the driving member controlling the blocking member to rise or fall.

[0015] In one embodiment, the drive element includes a drive cylinder.

[0016] In one embodiment, a driven wheel is also included, mounted on the mounting body and located at the other end of the mounting body, and the flat-top chain is looped around the outer surfaces of the driving wheel and the driven wheel.

[0017] In one embodiment, the flat-top chain is formed by sequentially splicing multiple chain plates, each chain plate having a first connecting part and a second connecting part, wherein the first connecting part of one chain plate is hinged to the second connecting part of another chain plate.

[0018] Secondly, this utility model also provides an electroplating equipment production line, comprising:

[0019] Multiple brackets, installed on the ground;

[0020] The flat-top chain, as described above, is coupled with a buffer device for the hanging roller, and the buffer device is mounted on the bracket.

[0021] Beneficial effects: Since the electroplating equipment production line includes the above-mentioned flat-top chain with hanger roller buffer device, it has the same effect as the flat-top chain with hanger roller buffer device, and will not be described in detail here.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] According to embodiments of the present invention, such as Figures 1 to 4 As shown, a buffer device with a flat-top chain and a hanging roller is provided, including: a mounting body 100; a drive motor 200 connected to the side of the mounting body 100 and located at one end of the mounting body 100, the output shaft of the drive motor 200 being rotatably connected to a drive wheel; a flat-top chain 300 sleeved on the outer surface of the drive wheel; and a hanging device 400, with rolling components on both sides of the hanging device 400, the rolling components abutting against the upper surface of the flat-top chain 300 and rolling freely on the upper surface of the flat-top chain 300.

[0032] In this embodiment, the mounting body 100 is the basic structure of the entire buffer device, used to support and fix the drive motor 200, the drive wheel, and the flat-top chain 300, to ensure stable operation and coordinated work between the drive motor 200, the drive wheel, and the flat-top chain 300. The mounting body 100 includes a pair of receiving slots located on the same horizontal plane, which are formed by two oppositely arranged side plates and a bottom plate, and have an opening at the top of the receiving slot.

[0033] The drive motor 200 serves as the power source, mounted on the mounting body 100 and fixedly connected to the side plate on the outer side of the mounting body 100. The drive wheel is located on the other side of the side plate, and the output shaft of the drive motor 200 passes through this side plate and is rotatably connected to the drive wheel. The flat-top chain 300 is disposed in the receiving groove and sleeved on the drive wheel, performing cyclical motion under the drive of the drive wheel. The upper surface of the flat-top chain 300 is flat, providing stable support and a rolling surface for the rolling components of the hanger 400.

[0034] The hanger 400 is used to carry materials to be conveyed or temporarily stored. Multiple rolling components are provided on both sides of the hanger 400. These rolling components abut against the upper surface of the flat-top chain 300 and can roll freely on the upper surface of the flat-top chain 300. During the operation of the drive motor 200, the drive motor 200 provides driving force to drive the output shaft to rotate. The output shaft transmits the driving force to the drive wheel to drive the drive wheel to rotate. The drive wheel then transmits the driving force to the flat-top chain 300, which is sleeved on the outer surface of the drive wheel, thereby driving the flat-top chain 300 to move. The upper surface of the flat-top chain 300 generates a horizontal frictional force on the rolling components, thereby driving the rolling components to move, and also causing the entire hanger 400 to move synchronously with the flat-top chain 300.

[0035] In this invention, the flat-top chain 300 is typically made of metal, making it more wear-resistant. By setting rolling components on both sides of the hanger 400, the rolling components abut against the upper surface of the flat-top chain 300, allowing the rolling components to roll freely relative to the flat-top chain 300. This allows the hanger 400 to be placed directly above the flat-top chain 300 without needing to engage with the teeth, effectively reducing the failure rate of the buffer device and thus reducing the maintenance frequency.

[0036] In one embodiment, the rolling assembly includes a support column 410 and a roller 420. The support column 410 is fixedly connected to both sides of the hanger 400, and the roller 420 is rotatably sleeved on the support column 410 and abuts against the upper surface of the flat-top chain 300.

[0037] In this embodiment, support columns 410 are fixedly connected to both sides of the hanger 400, and the support columns 410 are symmetrically welded to the sides of the hanger 400, so that the support columns 410 and the hanger 400 are integrally set to ensure the balance of the hanger 400 and ensure that the rolling assembly and the hanger 400 are a whole, preventing the hanger 400 from shaking or falling off during movement. The inner diameter of the roller 420 is slightly larger than the outer diameter of the support column 410, so that the roller 420 can be sleeved on the support column 410 and allows the roller 420 to rotate around the axis of the support column 410. After the roller 420 is sleeved on the support column 410, a blocking part is also provided on the outside of the support column 410. The diameter of the blocking part is larger than the inner diameter of the roller 420 to limit the radial displacement of the roller 420 and prevent the roller 420 from falling off the support column 410. The roller 420 directly abuts against the upper surface of the flat-top chain 300. The weight of the hanger 400 and the material is transferred to the support column 410 through the hanger 400 body, and then transferred to the roller 420 below by the support column 410. Finally, the roller 420 presses down on the flat-top chain 300. The roller 420 can convert sliding friction into rolling friction. If the hanger 400 is in direct contact with the flat-top chain 300, a large amount of sliding friction will be generated between the hanger 400 and the flat-top chain 300, which will easily wear the flat-top chain 300 and the hanger 400, and require more power to drive. After the roller 420 is fitted onto the support column 410, the roller 420 will rotate around the support column 410 with the movement of the flat-top chain 300. At this time, the friction between the hanger 400 and the chain becomes rolling friction between the roller 420 and the flat-top chain 300, which can reduce the friction between the hanger 400 and the flat-top chain 300 and reduce the wear of the parts, so that the hanger 400 can move more smoothly on the flat-top chain 300.

[0038] During the operation of the drive motor 200, the drive motor 200 provides driving force to drive the output shaft to rotate. The output shaft transmits the driving force to the drive wheel to drive the drive wheel to rotate. The drive wheel then transmits the driving force to the flat-top chain 300 sleeved on the outer surface of the drive wheel, thereby driving the flat-top chain 300 to move. The upper surface of the flat-top chain 300 generates a horizontal frictional force on the roller 420 to drive the roller 420 to rotate around the axis of the support column 410. At the same time, the hanger 400 is rigidly connected to the roller 420 through the support column 410. The rotation of the roller 420 will drive the entire hanger 400 to move synchronously with the flat-top chain 300.

[0039] In one embodiment, a limiting structure is also included, which is installed on both sides of the mounting body 100 to limit the movement of the hanger 400.

[0040] In this embodiment, the limiting structures are fixed on both sides of the mounting body 100, that is, on the left and right sides of the running track of the flat-top chain 300, and are continuously arranged along the running direction of the flat-top chain 300, thereby covering the entire movement path of the hanger 400 and avoiding any unprotected blind spots. The limiting structures on the left and right sides are symmetrically distributed, so that a channel matching the width of the hanger 400 is formed between the two limiting structures. The width of this channel is slightly larger than the width of the hanger 400, so that the limiting structures do not affect the normal movement of the hanger 400, while also limiting the excessive deviation of the hanger 400.

[0041] The hanger 400 is supported on the flat-top chain 300 by rollers 420 on both sides. If the running speed of the flat-top chain 300 fluctuates, the material on one side of the hanger 400 is too heavy, or the rollers 420 are worn and cannot rotate smoothly, the hanger 400 may shift to one side. If there is no limiting structure and the shift is too large, the hanger 400 may slip directly off the edge of the flat-top chain 300, causing material to fall, the buffer device to stop or malfunction, etc. By setting limiting structures on both sides of the mounting body 100, the rollers 420 of the hanger 400 can be stopped when the hanger 400 shifts to a preset range, preventing the rollers 420 of the hanger 400 from derailing.

[0042] In one embodiment, the limiting structure includes a first connector 510, a second connector 520, and a limiting rod 530. One end of the first connector 510 is connected to the mounting body 100, and the other end extends out of the upper surface of the flat-top chain 300. The second connector 520 is connected to the first connector 510 and extends above the flat-top chain 300. The limiting rod 530 is connected to the second connector 520.

[0043] In this embodiment, the limiting structure consists of a first connecting member 510, a second connecting member 520, and a limiting rod 530. First, the first connecting members 510 on both sides are installed on the left and right sides of the mounting body 100, extending beyond the upper surface of the flat-top chain 300, ensuring that the heights of the first connecting members 510 on both sides are consistent, thus laying the foundation for the positioning of subsequent components. Then, the second connecting member 520 is fixed to the upper end of the first connecting member 510, and the horizontal extension length of the second connecting member 520 is adjusted to ensure that both second connecting members 520 on both sides extend towards the flat-top chain 300, and that the distance between the two second connecting members 520 after extension is slightly greater than the maximum width of the hanger 400, thus determining the lateral position for the subsequent installation of the limiting rod 530. Finally, the limiting rod 530 is fixed to the horizontal end of the second connecting member 520, ensuring that the limiting rod 530 is parallel to the running direction of the flat-top chain 300, and that the heights of the limiting rods 530 on both sides are the same. At this time, the limiting rods 530 on both sides form a channel parallel to the flat top chain 300. When the hanger 400 runs in this channel, if the hanger 400 deviates to the left or right, the limiting rods 530 will block the rollers 420 of the hanger 400, thereby constraining the hanger 400 in the left and right directions and preventing the rollers 420 from deviating from the flat top chain 300.

[0044] In one embodiment, a blocking structure is also included, mounted on the mounting body 100, for restricting the movement of the hanger 400.

[0045] In this embodiment, the blocking structure is installed on the mounting body 100 and located at one end of the mounting body 100 near the drive motor 200. When the buffer hanger 400 is in operation, the blocking structure blocks the first hanger 400. Since the hanger 400 is mounted on the flat-top chain 300 via a rolling assembly, although the flat-top chain 300 is still running, the rolling assembly will slip relative to the hanger 400, preventing the hanger 400 from moving forward. Subsequent hangers 400 carried by the flat-top chain 300 will be blocked by the previous hanger 400. The rolling assembly on the hanger 400 will also slip relative to the flat-top chain 300, causing the hangers 400 that need to be temporarily stored to be in close contact with each other, thus achieving the purpose of temporarily storing the hangers 400. Moreover, there are no gaps between the hangers 400, saving storage space, increasing the storage density of the hangers 400, and improving the space utilization of the buffer device.

[0046] In one embodiment, the blocking structure includes a drive member and a blocking member 610, the blocking member 610 being drive-connected to the drive member, the drive member controlling the blocking member 610 to rise or fall. Further, the drive member includes a drive cylinder.

[0047] In this embodiment, the blocking structure consists of a driving member and a blocking member 610. The blocking member 610 is driven by the driving member, which provides driving force to control the rising or falling of the blocking member 610. When the driving member is a driving cylinder, the blocking member 610 is driven by the piston rod of the driving cylinder. When it is necessary to block the hanger 400 so that the hanger 400 is buffered on the buffer device, compressed air enters the rodless chamber of the driving cylinder to push the piston rod out. The blocking member 610 connected to the piston rod rises accordingly until it extends beyond the upper surface of the flat-top chain 300, blocking the movement path of the hanger 400. When the hanger 400 moves with the flat-top chain 300, it is blocked by the rising blocking member 610. Since the flat-top chain 300 is still running and the roller 420 of the hanger 400 can roll freely on the flat-top chain 300, the roller 420 will slip in place at the blocked position, thereby blocking the hanger 400 at the blocked position to achieve buffering of the hanger 400.

[0048] When the hanger 400 needs to continue moving, compressed air enters the rod chamber of the drive cylinder to push the piston rod back. The blocking member 610 descends synchronously with the piston rod until it is below the upper surface of the flat-top chain 300, so that the blocking member 610 no longer obstructs the path of the hanger 400. The hanger 400 continues to move under the drive of the flat-top chain 300. The blocking member 610 can be a stop block or a baffle. By using a drive cylinder as the driving component, the start or stop time of the cylinder's extension and retraction is short, which can quickly intercept the moving hanger 400 and prevent the hanger 400 from exceeding the blocking position due to inertia. Moreover, as long as the air source pressure is stable, the extension and retraction stroke of the drive cylinder is fixed, ensuring that the blocking position is consistent each time, and its operation is stable and reliable. It is understood that the driving component can also be a motor, hydraulic cylinder, etc., and the specific design can be customized according to actual usage requirements.

[0049] Other possible implementations include a sensor and a solenoid valve, with the sensor electrically connected to the solenoid valve, which in turn connects to the air supply. When the hanger 400 moves to a blocking position or needs to be buffered on a buffer device, the sensor generates a blocking command and sends it to the solenoid valve. Upon receiving the blocking command, the solenoid valve opens and transmits compressed air to the rodless chamber of the drive cylinder to extend the piston rod. When the hanger 400 needs to be released, the solenoid valve generates a directional command and sends it to the solenoid valve. Upon receiving the release command, the solenoid valve switches the air supply direction, and compressed air enters the rod chamber of the drive cylinder to retract the piston rod.

[0050] In one embodiment, a driven wheel is also included, which is mounted on the mounting body 100 and located at the other end of the mounting body 100, and a flat-top chain 300 is looped around the outer surfaces of the driving wheel and the driven wheel.

[0051] In this embodiment, a driven wheel is also provided at the other end of the mounting body 100. The flat-top chain 300 is annularly sleeved on the outer surfaces of the driving wheel and the driven wheel, thus forming a complete closed loop. The driving motor 200 provides driving force to drive the driving wheel to rotate; the teeth of the driven wheel mesh with the annular flat-top chain 300, and the rotational force of the driving wheel is converted into the linear traction force of the chain, thereby driving the flat-top chain 300 to move in a clockwise or counterclockwise direction; since the driven wheel is located at the other end of the mounting body 100 and meshes with the flat-top chain 300, when the flat-top chain 300 moves, it can drive the driven wheel to rotate passively, so that the driven wheel rotates with the movement of the flat-top chain 300, and the driven wheel can change the direction of movement of the flat-top chain 300, thereby realizing the cyclic movement of the flat-top chain 300 around the driving wheel and the driven wheel.

[0052] In one embodiment, the flat-top chain 300 is formed by sequentially splicing multiple chain plates 310. Each chain plate 310 is provided with a first connecting part 311 and a second connecting part 312. The first connecting part 311 on one chain plate 310 is hinged to the second connecting part 312 on another chain plate 310.

[0053] In this embodiment, the flat-top chain 300 is formed by sequentially hinged and spliced ​​multiple independent chain plates 310 through pins or connectors to form a continuous, flexible annular flat-top chain 300. When the chain passes around the driving and driven wheels, the chain plates 310 can rotate around the pins, allowing the arc surfaces that fit against the driving and driven wheels to complete the turning, preventing the flat-top chain 300 from jamming due to excessive rigidity. Moreover, if the flat-top chain 300 is partially worn, it is not necessary to replace the entire flat-top chain 300; only the damaged chain plates 310 need to be replaced, reducing maintenance costs. At the same time, the total length of the flat-top chain 300 can be flexibly adjusted by increasing or decreasing the number of chain plates 310 to adapt to different sizes of mounting bodies 100.

[0054] Furthermore, each chain plate 310 is provided with a first connecting part 311 and a second connecting part 312, which are located on both sides of the chain plate 310. The first connecting part 311 on one chain plate 310 is hinged to the second connecting part 312 on another chain plate 310, so that multiple chain plates 310 are hinged to each other to form a complete annular flat-top chain 300. Both the driving wheel and the driven wheel are gears. The connection between the first connecting part 311 and the second connecting part 312 has a protrusion, which is engaged between two teeth of the driving wheel or the driven wheel, thereby realizing the meshing of the flat-top chain 300 with the driving wheel and the driven wheel, so as to facilitate the movement of the flat-top chain 300.

[0055] On the other hand, this utility model also provides an electroplating equipment production line, including: multiple supports 10 installed on the ground; and a buffer device with a flat-top chain and hanging rollers as described above, the buffer device being installed on the supports 10. Since the electroplating equipment production line includes the aforementioned buffer device with a flat-top chain and hanging rollers, it has the same effect as the buffer device with a flat-top chain and hanging rollers, and will not be described in detail here.

[0056] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0057] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
