Description

Technical Field

[0001] This utility model relates to the field of electroplating equipment technology, and in particular, to a fully automatic electroplating rack transfer and lifting machine. Background Technology

[0002] In an electroplating production system, a track typically includes multiple racks slidably connected along it. These racks are driven by a chain drive and can move along the track, with equal distances maintained between adjacent racks. Shelves for holding products to be electroplated or already electroplated are suspended from these racks. In a typical production process, the shelves for finished electroplated products (i.e., the first shelf) and the shelves for products to be electroplated (i.e., the second shelf) are both located on the same track.

[0003] In the prior art, equipment for transferring material racks between a track system and an electroplating machine, for example, Figure 1 The electroplating material transfer and lifting machine shown generally consists of a slide rail 1, a support frame 2, a cylinder 28, and a hook 29. The support frame 2 is mounted on the slide rail 1 and is driven by a motor to reciprocate along the slide rail 1. The cylinder 28 is vertically fixed to the support frame 2, and the end of its shaft is connected to the hook 29. By controlling the extension and retraction of the cylinder 28, the hook 29 can move up and down, thereby hooking or releasing the material rack.

[0004] The working process of the existing electroplating material transfer and lifting machine is as follows: First, the support frame 2 moves along the slide rail 1 towards the electroplating machine, causing the hook 29 to rise and lift the first material rack 9, which has completed electroplating, from the electroplating machine. Next, the support frame 2 moves back along the slide rail 1 towards the track 31, the hook 29 descends, and the first material rack 9 is hooked back onto the hanger 30 on the track 31, detaching from the first material rack 9. Then, the support frame 2 moves a short distance away from the first hanger 30 along the slide rail 1 to adjust the position of the hanger 30 on the track 31 via chain drive, so that the second material rack 10 to be electroplated moves to the position corresponding to the hook 29. After that, the support frame 2 moves again along the slide rail 1 towards the track 31, and removes the second material rack 10 from the hanger 30 via the hook 29. Finally, the support frame 2 moves along the slide rail 1 towards the electroplating machine, and hangs the second material rack 10 onto the electroplating machine.

[0005] However, this existing technical solution has inefficiencies. In particular, after the first rack is hung back on the hanger, it is necessary to wait for the second rack on the track to move into place and align with the hook of the transfer and lifting machine. This introduces an unnecessary time delay and reduces the operating efficiency of the entire electroplating production system. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a fully automatic electroplating rack transfer and lifting machine to improve production efficiency.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a fully automatic electroplating rack transfer and lifting machine, including a slide rail and a support frame. The support frame is driven by a power structure and moves back and forth along the length direction of the slide rail. It also includes a first hook and a second hook slidably connected to the support frame. The first hook is used to hook a first rack, and the second hook is used to hook a second rack. The distance between the first hook and the second hook is equal to the distance between the first rack and the second rack. The support frame is provided with a drive mechanism for driving the first hook and the second hook to move synchronously in opposite directions.

[0008] To achieve the above technical solution, the support frame, driven by a power structure, moves along the slide rail to the vicinity of the electroplating machine. When it reaches this point, the first hook on the support frame lifts the first material rack from the electroplating machine. Subsequently, the support frame moves to the track system, the drive mechanism activates, the first hook descends, precisely hooking the first material rack onto a designated empty rack on the track and then releasing it. The distance between the first and second hooks is equal to the distance between adjacent material racks on the track. Simultaneously with or very briefly after the first hook's placement action, the second hook rises to hook the second material rack. Immediately afterward, the support frame moves back to the electroplating machine, and the second hook descends to place the second material rack into the machine. During this process, the empty rack on the track moves forward a certain distance, aligning its position with the first hook. The placement of the first material rack and the retrieval of the second material rack are performed almost simultaneously, significantly reducing or even eliminating the time delay caused by waiting for the track to align with a single hook in the prior art. Therefore, the operating efficiency of the material transfer and lifting machine is improved, thereby enhancing the production cycle time and automation level of the entire electroplating production line.

[0009] In a preferred embodiment of this utility model, the driving mechanism includes a driving block, a first support roller, and a second support roller. The first support roller is fixed on a first hook, and the second support roller is fixed on a second hook. The driving block is driven by a driving assembly and reciprocally slidably connected to a support frame. A first inclined surface and a second inclined surface are respectively provided on both sides of the driving block. The inclination directions of the first inclined surface and the second inclined surface are opposite and the inclinations are equal. The first support roller abuts against the first inclined surface, and the second support roller abuts against the second inclined surface.

[0010] To achieve the above technical solution, the drive block is driven by the drive assembly to slide horizontally back and forth on the support frame. Since the support rollers fixed on the first hook and the second hook respectively abut against the first inclined plane and the second inclined plane on the drive block with opposite inclination directions and equal inclination, the horizontal movement of the drive block cleverly transforms the horizontal constraint of the rollers into the vertical movement of the first and second hooks. When the drive block slides to one side, the first hook rises or falls vertically under the action of the first inclined plane, while the second hook falls or rises vertically under the action of the second inclined plane, and vice versa. This achieves synchronous movement of the first hook and the second hook with equal distance and opposite direction in the vertical direction, thus providing a reliable and efficient way to mechanically control the lifting and lowering of the two hooks.

[0011] In a preferred embodiment of this utility model, the driving assembly includes a drive motor, a threaded shaft, and a guide rod. The drive motor is fixed on the support frame and drives the threaded shaft to rotate. The threaded shaft is rotatably connected to the support frame. The guide rod is fixed on the support frame and is arranged parallel to the threaded shaft. The drive block is threadedly connected to the threaded shaft and slidably connected to the guide rod.

[0012] To achieve the above technical solution, the drive motor is fixed on the support frame and rotates the threaded shaft; the drive block is threadedly connected to the rotating threaded shaft, and at the same time, it is prevented from rotating by sliding connection with the guide rod, so as to accurately convert the rotational motion of the threaded shaft into the linear reciprocating sliding of the drive block along the axial direction; thus providing the drive block with stable, controllable and precisely positioned horizontal movement capability.

[0013] In a preferred embodiment of this utility model, a first bevel gear is connected to the drive shaft of the drive motor, the first bevel gear being coaxially arranged with the drive shaft, and a second bevel gear meshing with the first bevel gear is connected to the threaded shaft, the second bevel gear being coaxially arranged with the threaded shaft.

[0014] The above technical solution is achieved by transmitting power through the meshing of the first bevel gear on the drive shaft and the second bevel gear on the threaded shaft. This can efficiently and reliably transmit the rotational power of the drive motor to the threaded shaft, and is especially suitable when the axes of the drive motor and the threaded shaft are arranged perpendicularly, providing flexibility in layout while ensuring that the threaded shaft can rotate stably.

[0015] In a preferred embodiment of this utility model, a first stabilizing tube and a second stabilizing tube are fixedly connected to the lower surface of the support frame, the first hook is slidably connected in the first stabilizing tube, and the second hook is slidably connected in the second stabilizing tube.

[0016] To achieve the above technical solution, the first and second stabilizing tubes are fixedly connected to the lower surface of the support frame, and the corresponding hooks are slidably connected inside the stabilizing tubes; this provides stable and precise guidance for the vertical lifting and lowering of the two hooks, effectively preventing the hooks from swaying, tilting or rotating during the lifting and lowering process, and ensuring that the hooks always maintain the correct posture.

[0017] As a preferred embodiment of this utility model, a reinforcing rod is fixedly connected between the first stabilizing tube and the second stabilizing tube.

[0018] The above technical solution enhances the rigidity and stability of the overall structure of the first and second stabilizing tubes by strengthening the rod; it prevents the first and second stabilizing tubes from deforming or shifting inward or outward due to force during use, thus ensuring a precise and fixed spacing between the first and second stabilizing tubes.

[0019] As a preferred embodiment of this utility model, the power structure includes a power motor and a power wheel. The power motor is fixed on the support frame and drives the power wheel to rotate. The power wheel is rotatably connected to the slide rail and rotatably connected to the support frame.

[0020] To achieve the above technical solution, the power motor is fixed on the support frame and drives the power wheel to rotate. The power wheel is rolled on a fixed slide rail on one side and rotated on the support frame on the other side. When the power wheel rotates, it generates thrust through rolling friction with the slide rail, driving the support frame to move horizontally in a straight line along the slide rail.

[0021] In a preferred embodiment of this utility model, a first rotating wheel coaxially connected to the first support roller, and a second rotating wheel coaxially connected to the second support roller, wherein the first rotating wheel is rolled on the first inclined surface, and the second rotating wheel is rolled on the second inclined surface.

[0022] By implementing the above technical solution, the original sliding friction contact between the support roller and the inclined plane is changed to rolling friction contact between the wheel and the inclined plane. Rolling friction is much less than sliding friction, which significantly reduces the frictional resistance during operation, making the horizontal movement of the drive block smoother and less strenuous. At the same time, it reduces the wear of components, improves transmission efficiency and service life, and helps to achieve more stable and precise lifting and lowering movements of the first hook and the second hook.

[0030] The following is in conjunction with the appendix Figure 2 To be continued Figure 5 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0031] An automatic electroplating rack transfer and lifting machine includes a slide rail 1 and a support frame 2. The support frame 2 is driven by a power structure 3 and moves back and forth along the length of the slide rail 1.

[0032] The power structure 3 includes a power motor 4 and a power wheel 5. The power motor 4 is a servo motor, which is fixed to the support frame 2 and drives the power wheel 5 to rotate. The power wheel 5 is rolledly connected to the upper surface of the slide rail 1 and rotatably connected to the support frame 2.

[0033] To improve stability, a limiting wheel 6 is rotatably connected to the side wall of the support frame 2, and the limiting wheel 6 is rolledly connected to the side wall of the slide rail 1. The axis of the drive wheel 5 is horizontally set, and the axis of the limiting wheel 6 is vertically set. The slide rail 1 is horizontally set.

[0034] A first hook 7 and a second hook 8 are slidably connected to the support frame 2, and both the first hook 7 and the second hook 8 move vertically. The first hook 7 is used to hook the first material rack 9, and the second hook 8 is used to hook the second material rack 10. The distance between the first hook 7 and the second hook 8 is equal to the distance between the first material rack 9 and the second material rack 10.

[0035] A drive mechanism 11 is provided on the support frame 2 for driving the first hook 7 and the second hook 8 to move synchronously in opposite directions.

[0036] The drive mechanism 11 includes a drive block 12, a first support roller 13, and a second support roller 14. The first support roller 13 is fixed to the first hook 7 by a first support rod, and the second support roller 14 is fixed to the second hook 8 by a second support rod. A first rotating wheel 15 is rotatably connected to the first support roller 13, and a second rotating wheel 16 is rotatably connected to the second support roller 14.

[0037] The drive block 12 is slidably connected to the support frame 2, and is located between the first hook 7 and the second hook 8. A first inclined surface 17 and a second inclined surface 18 are respectively formed on both sides of the drive block 12. The inclination directions of the first inclined surface 17 and the second inclined surface 18 are opposite and their slopes are equal. The first rotating wheel 15 is rotatably connected to the first inclined surface 17, and the second rotating wheel 16 is rotatably connected to the second inclined surface 18.

[0038] The drive assembly 19 includes a drive motor 20, a threaded shaft 21, and a guide rod 22. The drive motor 20 is fixed to the support frame 2 and drives the threaded shaft 21 to rotate; the drive motor 20 is a servo motor. The threaded shaft 21 is rotatably connected to the support frame 2 and is horizontally positioned. The guide rod 22 is fixed to the support frame 2 and is parallel to the threaded shaft 21. The drive block 12 is threadedly connected to the threaded shaft 21 and slidably connected to the guide rod 22.

[0039] A first bevel gear 23 is fixedly connected to the drive shaft of the drive motor 20, and the drive shaft and the first bevel gear 23 are coaxially arranged. A second bevel gear 24 that meshes with the first bevel gear 23 is fixedly connected to the threaded shaft 21, and the second bevel gear 24 is coaxially arranged with the threaded shaft 21. The drive motor 20 is vertically arranged.

[0040] A first stabilizing tube 25 and a second stabilizing tube 26 are fixedly connected to the lower surface of the support frame 2. A first hook 7 is slidably connected to the first stabilizing tube 25, and a second hook 8 is slidably connected to the second stabilizing tube 26.

[0041] A reinforcing rod 27 is fixedly connected between the first stabilizing tube 25 and the second stabilizing tube 26.

[0042] The power motor 4 in the power structure 3 is fixed on the support frame 2 and drives the power wheel 5 to rotate. The power wheel 5 is rolledly connected to the upper surface of the slide rail 1 and rotatably connected to the support frame 2, thereby driving the support frame 2 to move horizontally back and forth along the slide rail 1. The limiting wheel 6 rolls on the side wall of the slide rail 1 to provide lateral stability.

[0043] When the support frame 2 moves to a position close to the electroplating machine, the drive block 12 slides horizontally along the threaded shaft 21 and the guide rod 22. Through the rolling engagement of the first inclined surface 17 and the first rotating wheel 15, the first rotating wheel 15 rolls to the upper end of the first inclined surface 17, causing the first hook 7 to rise and lift the first material rack 9 from the electroplating machine. At the same time, the second roller rolls to the lower end of the second inclined surface 18, and the second hook 8 descends.

[0044] Next, the support frame 2 moves horizontally above the track 31 system via the power structure 3, positioning itself in a suitable position so that the first hook 7 aligns with the empty rack 30 to be placed, and the second hook 8 aligns with the second material rack 10 to be hooked. At this time, the drive block 12 slides horizontally again. Since the first inclined plane 17 and the second inclined plane 18 have opposite inclination directions and equal inclination, the first hook 7 places the first material rack 9 onto the rack 30 and disengages it, while the second hook 8 hooks the second material rack 10 to be electroplated from the rack 30, achieving synchronous reverse vertical movement of "placing and retrieval".

[0045] Finally, the support frame 2 moves horizontally to the electroplating machine position again via the power structure 3, bringing the second material rack 10 hooked on the second hook 8 above the electroplating machine. The drive assembly 19 then drives the drive block 12 to move, causing the second hook 8 to descend and securely place the second material rack 10 into the electroplating machine. At the same time, the first hook 7 lifts the first material rack 9 on the electroplating machine, completing the entire material transfer cycle.

[0046] Compared to existing cylinder-driven hooks, this patent application features inherently high-precision mechanical synchronization. Unlike systems that require complex control systems to coordinate the movement of independent cylinders to achieve synchronization, this mechanical structure ensures that the vertical movements of the first hook 7 and the second hook 8 are highly synchronized and opposite in direction through physical linkage, greatly simplifying the complexity of the control system. Furthermore, combined with precision transmission components such as the threaded shaft 21, this mechanical linkage method makes it easier to achieve precise control and positioning of the vertical movements of the first hook 7 and the second hook 8, thus providing a more reliable, accurate, and easy-to-maintain hook synchronous lifting function than independent cylinder solutions.

[0047] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
