Description

Technical Field

[0001] This invention relates to the field of safety pin electroplating technology, and in particular to a safety pin electroplating device for elevator processing. Background Technology

[0002] In elevator manufacturing, safety pins are critical components, and their surfaces typically require electroplating to improve corrosion resistance, wear resistance, and aesthetics. Traditional safety pin electroplating processes mostly rely on manual operation or semi-automated equipment, resulting in low efficiency, high labor intensity, and inconsistent plating quality. Existing technologies typically use fixed plating tanks, requiring manual placement of each safety pin into the plating solution, followed by removal after plating. This method is not only inefficient but also prone to uneven plating due to improper operation, potentially affecting product performance. Furthermore, while some automated plating equipment can achieve continuous feeding, its complex structure, high maintenance costs, and inability to adapt to the plating requirements of safety pins of different specifications are significant challenges. Therefore, there is an urgent need for a highly automated, easy-to-operate, and stable safety pin electroplating device to improve production efficiency, reduce labor costs, and ensure uniform and consistent plating quality. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention adopts the following technical solution: an electroplating device for safety pins in elevator processing, comprising a working mechanism for electroplating safety pins, the working mechanism comprising an electroplating tank, and the working mechanism being provided with a feeding mechanism for continuously feeding safety pins into the working mechanism and a delivery mechanism for delivering electroplated safety pins out.

[0004] The working mechanism includes a conveyor frame fixedly installed on the electroplating box, an electric cylinder frame fixedly installed on the conveyor frame, a top electric cylinder fixedly installed on the electric cylinder frame, a placement plate fixedly installed on the output end of the top electric cylinder, and a lower pressure plate and a vertical rack fixedly installed on the placement plate.

[0005] Furthermore, the working mechanism also includes a connecting frame fixedly installed on the electroplating tank, an inner guide frame fixedly installed on the connecting frame, two electrodes are provided inside the electrode, namely an anode and a cathode, and the electroplating tank is filled with electroplating solution.

[0006] When the safety pin reaches the placement plate, the top electric cylinder extends, causing the placement plate, lower pressure plate, and vertical rack to descend. The placement plate then guides the safety pin into the electrode. The safety pin is guided by the inner guide frame, and the two electrodes work together with the electroplating solution in the electroplating tank to electroplat the safety pin. After electroplating is completed, the top electric cylinder retracts, and the placement plate causes the safety pin to leave the electrode, making the upper surface of the placement plate flush with the upper surface of the conveyor frame.

[0007] Furthermore, the feeding mechanism includes a feeding frame fixedly installed on the conveyor frame, a lower drive shaft and a double-acting screw rotatably installed below the feeding frame, the lower drive shaft drives the double-acting screw to rotate through a bottom drive belt, a push frame is slidably installed inside the feeding frame, the push frame and the double-acting screw form a threaded transmission, a slide rod is slidably installed on the push frame, a push plate is fixedly installed on the slide rod, a slide rod spring is provided between the push plate and the push frame, and multiple safety pins are placed inside the feeding frame, with the push plate and safety pins in contact.

[0008] Furthermore, a drive motor is fixedly installed on the feed rack, a drive wheel is fixedly installed on the motor shaft of the drive motor, another drive wheel is rotatably installed on the conveyor rack, a toggle belt is wound around the two drive wheels, multiple toggle rods are rotatably installed on the toggle belt, and a torsion spring is provided between the toggle rods and the toggle belt.

[0009] Furthermore, a one-way gear and an inner ratchet are rotatably mounted on the electroplating box. Two ratchet bars are rotatably mounted on the inner ratchet, and the ratchet bars mesh with the inner ratchet. A transmission wheel is fixedly mounted on the inner ratchet. The one-way gear meshes with a vertical rack, and a transmission belt is wound around the transmission wheel and the lower transmission shaft.

[0010] When the rack descends, it drives the one-way gear to rotate. At this time, the ratchet bar rotates relative to the one-way gear, but the ratchet bar does not drive the inner ratchet to rotate. When the rack rises, it drives the one-way gear to rotate. At this time, the ratchet bar drives the inner ratchet and the transmission wheel to rotate. The transmission belt drives the lower transmission shaft to rotate, and the bottom transmission belt drives the double-acting screw to rotate. This causes the pusher to slide along the feed frame. The push plate pushes the foremost safety pin onto the conveyor frame, and the slide bar spring provides support. The drive motor rotates, driving the drive wheel to rotate, which in turn drives the actuating belt to move. The actuating rod moves the safety pin that has just been pushed onto the conveyor frame onto the placement plate. At the same time, the actuating rod pushes the electroplated safety pin to the connecting plate. When the safety pin reaches the connecting plate, it cannot be pushed any further. At this time, the actuating rod rotates relative to the actuating belt, and the torsion spring between the actuating rod and the actuating belt is twisted. After the actuating rod passes the safety pin, the torsion spring drives the actuating rod to reset.

[0011] Furthermore, the delivery mechanism includes a pop-out column slidably mounted on the connecting plate, an ejection plate fixedly mounted on the pop-out column, a pop-out spring provided between the ejection plate and the connecting plate, and a pop-out plate fixedly mounted on the pop-out column.

[0012] Furthermore, a column is fixedly installed on the electroplating box, a pressure rod is slidably installed on the column, a column spring is provided between the pressure rod and the column, a one-way rotating rod is rotatably installed on the pressure rod, a torsion spring is provided between the one-way rotating rod and the pressure rod, a pop-out rod is rotatably installed on the conveyor frame, the pop-out rod cooperates with the pop-out plate, and a reset torsion spring is provided between the pop-out rod and the conveyor frame.

[0013] Furthermore, a fixed ramp is fixedly installed on the electroplating box, a sliding block is slidably installed on the pressure rod, an inner spring is provided between the sliding block and the pressure rod, and a connecting block is fixedly installed on the sliding block.

[0014] As the pressure plate descends, it causes the sliding block, the lowering rod, and the one-way rotating rod to descend as well. The column spring is compressed, and the one-way rotating rod causes the ejector rod to rotate. The ejector rod causes the ejector plate, ejector column, and ejection plate to slide along the connecting plate, and the ejector spring is compressed. When the one-way rotating rod passes the ejector rod, the ejector spring rebounds, and the ejector plate pushes the electroplated safety pin next to the connecting plate into the external collection basket for collection. When the docking block contacts the fixed ramp, the fixed ramp causes the docking block and the sliding block to slide along the lowering rod, and the inner spring is compressed, causing the sliding block to move away from below the lower pressure plate. Then, the column spring rebounds and resets, causing the lowering rod, the sliding block, and the one-way rotating rod to rise and reset. When the one-way rotating rod encounters the ejector rod, the torsion spring between the one-way rotating rod and the lower pressure rod twists, and then the one-way rotating rod reaches above the ejector rod. When the pressure plate rises, the pressure plate causes the sliding block to slide along the lower pressure rod through the slope of the sliding block, and the inner spring is compressed. Then, the pressure plate reaches above the sliding block and returns to its initial position.

[0015] The beneficial effects of this invention compared with the prior art are: (1) This invention achieves automatic feeding, electroplating and unloading of safety pins through the coordinated cooperation of the feeding mechanism, the working mechanism and the delivery mechanism, without manual intervention, which greatly improves production efficiency and reduces labor intensity; (2) The working mechanism set up in this invention adopts precise electrode positioning and internal guide frame guiding structure to ensure that the safety pin maintains a stable posture during the electroplating process, so that the electroplating solution is evenly covered, avoiding uneven plating thickness or missed plating, and improving the product qualification rate; (3) When the top electric cylinder set up in this invention extends, it drives the safety pin to be electroplated and sends out the safety pin that has been electroplated. When the top electric cylinder retracts, it drives the feeding mechanism to push out the next safety pin to be processed. The degree of automation is high and the continuity is good.

Detailed Implementation

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0028] Example: Figures 1-9As shown, an elevator processing safety pin electroplating device includes a working mechanism for electroplating safety pins 4. The working mechanism includes an electroplating tank 101. The working mechanism is provided with a feeding mechanism for continuously feeding the safety pins 4 into the working mechanism and a delivery mechanism for sending out the electroplated safety pins 4.

[0029] The working mechanism includes a conveyor frame 102 fixedly installed on the electroplating box 101, an electric cylinder frame 103 fixedly installed on the conveyor frame 102, a top electric cylinder 104 fixedly installed on the electric cylinder frame 103, a placement plate 105 fixedly installed on the output end of the top electric cylinder 104, and a lower pressure plate 106 and a vertical rack 107 fixedly installed on the placement plate 105.

[0030] like Figure 2 , Figure 3 As shown, the working mechanism also includes a connecting frame 109 fixedly installed on the electroplating tank 101. An inner guide frame 108 is fixedly installed on the connecting frame 109. Two electrodes 110 are provided inside the electrode 110, namely the anode and the cathode. The electroplating tank 101 is filled with electroplating solution.

[0031] When the safety pin 4 reaches the placement plate 105, the top electric cylinder 104 extends, causing the placement plate 105, the lower pressure plate 106, and the vertical rack 107 to descend. The placement plate 105 carries the safety pin 4 into the electrode 110. The safety pin 4 is guided by the inner guide frame 108. The two electrodes 110 work together with the electroplating solution in the electroplating tank 101 to electroplat the safety pin 4. After the electroplating is completed, the top electric cylinder 104 retracts, and the placement plate 105 drives the safety pin 4 to leave the electrode 110, so that the upper surface of the placement plate 105 is flush with the upper surface of the conveyor frame 102.

[0032] like Figures 4-7 As shown, the feeding mechanism includes a feeding frame 201 fixedly installed on the conveyor frame 102. A lower drive shaft 207 and a double-acting screw 209 are rotatably installed below the feeding frame 201. The lower drive shaft 207 drives the double-acting screw 209 to rotate through the bottom drive belt 208. A push frame 214 is slidably installed inside the feeding frame 201. The push frame 214 and the double-acting screw 209 form a threaded transmission. A slide rod 216 is slidably installed on the push frame 214. A push plate 215 is fixedly installed on the slide rod 216. A slide rod spring 217 is provided between the push plate 215 and the push frame 214. Multiple safety pins 4 are placed inside the feeding frame 201. The push plate 215 is in contact with the safety pins 4.

[0033] like Figures 4-7As shown, a drive motor 210 is fixedly installed on the feed rack 201. A drive wheel 211 is fixedly installed on the motor shaft of the drive motor 210. Another drive wheel 211 is rotatably installed on the conveyor rack 102. A toggle belt 212 is wound around the two drive wheels 211. Multiple toggle rods 213 are rotatably installed on the toggle belt 212. A torsion spring is provided between the toggle rods 213 and the toggle belt 212.

[0034] like Figures 4-7 As shown, a one-way gear 202 and an inner ratchet 203 are rotatably mounted on the electroplating tank 101. Two ratchet bars 204 are rotatably mounted on the inner ratchet 203. The ratchet bars 204 mesh with the inner ratchet 203. A transmission wheel 205 is fixedly mounted on the inner ratchet 203. The one-way gear 202 meshes with the vertical rack 107. A transmission belt 206 is wound around the transmission wheel 205 and the lower transmission shaft 207.

[0035] When the vertical rack 107 descends, it drives the one-way gear 202 to rotate. At this time, the ratchet 204 rotates relative to the one-way gear 202, but the ratchet 204 does not drive the inner ratchet 203 to rotate. When the vertical rack 107 rises, it drives the one-way gear 202 to rotate. At this time, the ratchet 204 drives the inner ratchet 203 and the transmission wheel 205 to rotate, which in turn drives the lower transmission shaft 207 to rotate via the transmission belt 206. The bottom transmission belt 208 drives the double-acting screw 209 to rotate, causing the pusher 214 to slide along the feed frame 201. The pusher plate 215 pushes the foremost safety pin 4 onto the conveyor frame 102, and the slide spring 21... 7 provides support force, drives the motor 210 to rotate, drives the drive wheel 211 to rotate, thereby driving the actuating belt 212 to move. The actuating rod 213 moves the safety pin 4 that has just been pushed onto the conveyor frame 102 to the placement plate 105. At the same time, the actuating rod 213 pushes the electroplated safety pin 4 to the connecting plate 301. When the safety pin 4 reaches the connecting plate 301, since the safety pin 4 can no longer be pushed, the actuating rod 213 rotates relative to the actuating belt 212. The torsion spring between the actuating rod 213 and the actuating belt 212 is twisted. When the actuating rod 213 passes the safety pin 4, the torsion spring drives the actuating rod 213 to reset.

[0036] like Figure 8 , Figure 9 As shown, the delivery mechanism includes a pop-out post 312 that is slidably mounted on the connecting plate 301, a push-out plate 313 that is fixedly mounted on the pop-out post 312, a pop-out spring 314 that is provided between the push-out plate 313 and the connecting plate 301, and a pop-out plate 311 that is fixedly mounted on the pop-out post 312.

[0037] like Figure 8 , Figure 9As shown, a column 303 is fixedly installed on the electroplating box 101, a downward pressure rod 305 is slidably installed on the column 303, a column spring 304 is provided between the downward pressure rod 305 and the column 303, a one-way rotating rod 306 is rotatably installed on the downward pressure rod 305, a torsion spring is provided between the one-way rotating rod 306 and the downward pressure rod 305, a pop-out rod 307 is rotatably installed on the conveyor frame 102, the pop-out rod 307 cooperates with the pop-out plate 311, and a reset torsion spring 310 is provided between the pop-out rod 307 and the conveyor frame 102.

[0038] like Figure 8 , Figure 9 As shown, a fixed ramp 302 is fixedly installed on the electroplating box 101, a sliding block 308 is slidably installed on the lower pressure rod 305, an inner spring 309 is provided between the sliding block 308 and the lower pressure rod 305, and a docking block 315 is fixedly installed on the sliding block 308.

[0039] When the pressure plate 106 descends, it causes the sliding block 308, the pressure rod 305, and the one-way rotating rod 306 to descend, compressing the column spring 304. The one-way rotating rod 306 drives the ejector rod 307 to rotate, and the ejector rod 307 drives the ejector plate 311, the ejector column 312, and the ejection plate 313 to slide along the connecting plate 301. The ejector spring 314 is compressed. When the one-way rotating rod 306 passes the ejector rod 307, the ejector spring 314 rebounds, and the ejector plate 313 pushes the electroplated safety pin 4 next to the connecting plate 301 into the external collection basket for collection. When the docking block 315 contacts the fixed ramp block 302, the fixed ramp block 302 drives the docking block 315 and the sliding block 308 to slide along the pressure rod 305, compressing the inner spring 309, causing the sliding block 308 to move away from below the pressure plate 106. Subsequently, the column spring 304 rebounds and resets, driving the pressure rod 305, the sliding block 308, and the ejector rod 306 to rotate. 08 and the one-way rotating rod 306 rise to reset. When the one-way rotating rod 306 encounters the pop-out rod 307, the torsion spring between the one-way rotating rod 306 and the lowering rod 305 twists. Then the one-way rotating rod 306 reaches above the pop-out rod 307. When the lowering plate 106 rises, the lowering plate 106 drives the sliding block 308 to slide along the lowering rod 305 through the slope of the sliding block 308. The inner spring 309 is compressed. Then the lowering plate 106 reaches above the sliding block 308 and returns to the initial position.

[0040] The working principle of the safety pin electroplating device for elevator processing disclosed in this invention is as follows: Multiple safety pins 4 are placed inside the feed rack 201. When the vertical rack 107 descends, it drives the one-way gear 202 to rotate. At this time, the ratchet bar 204 rotates relative to the one-way gear 202, but the ratchet bar 204 does not drive the inner ratchet 203 to rotate. When the vertical rack 107 rises, it drives the one-way gear 202 to rotate. At this time, the ratchet bar 204 drives the inner ratchet 203 and the transmission wheel 205 to rotate. The transmission belt 206 drives the lower transmission shaft 207 to rotate, and the bottom transmission belt 208 drives the double-acting screw 209 to rotate, causing the pusher 214 to slide along the feed rack 201. The push plate 215 pushes the foremost safety pin... The safety pin 4 is pushed onto the conveyor frame 102 and supported by the slide spring 217. The drive motor 210 rotates, driving the drive wheel 211 to rotate, which in turn drives the actuating belt 212 to move. The actuating rod 213 moves the safety pin 4, which has just been pushed onto the conveyor frame 102, onto the placement plate 105. At the same time, the actuating rod 213 pushes the electroplated safety pin 4 to the connecting plate 301. When the safety pin 4 reaches the connecting plate 301, it cannot be pushed any further. At this time, the actuating rod 213 rotates relative to the actuating belt 212, and the torsion spring between the actuating rod 213 and the actuating belt 212 is twisted. When the actuating rod 213 passes the safety pin 4, the torsion spring drives the actuating rod 213 to reset. When the safety pin 4 reaches the placement plate 105, the top electric cylinder 104 extends, causing the placement plate 105, the lower pressure plate 106, and the vertical rack 107 to descend. The placement plate 105 carries the safety pin 4 into the electrode 110. The safety pin 4 is guided by the inner guide frame 108. The two electrodes 110 work together with the electroplating solution in the electroplating tank 101 to electroplat the safety pin 4. After the electroplating is completed, the top electric cylinder 104 retracts, and the placement plate 105 drives the safety pin 4 to leave the electrode 110, so that the upper surface of the placement plate 105 is flush with the upper surface of the conveyor frame 102.When the pressure plate 106 descends, it causes the sliding block 308, the pressure rod 305, and the one-way rotating rod 306 to descend, compressing the column spring 304. The one-way rotating rod 306 drives the ejector rod 307 to rotate, and the ejector rod 307 drives the ejector plate 311, the ejector column 312, and the ejection plate 313 to slide along the connecting plate 301. The ejector spring 314 is compressed. When the one-way rotating rod 306 passes the ejector rod 307, the ejector spring 314 rebounds, and the ejector plate 313 pushes the electroplated safety pin 4 next to the connecting plate 301 into the external collection basket for collection. When the docking block 315 contacts the fixed ramp block 302, the fixed ramp block 302 drives the docking block 315 and the sliding block 308 to slide along the pressure rod 305, compressing the inner spring 309, causing the sliding block 308 to move away from below the pressure plate 106. Subsequently, the column spring 304 rebounds and resets, driving the pressure rod 305, the sliding block 308, and the ejector rod 306 to rotate. 08 and the one-way rotating rod 306 rise to reset. When the one-way rotating rod 306 encounters the pop-out rod 307, the torsion spring between the one-way rotating rod 306 and the lowering rod 305 twists. Then the one-way rotating rod 306 reaches above the pop-out rod 307. When the lowering plate 106 rises, the lowering plate 106 drives the sliding block 308 to slide along the lowering rod 305 through the slope of the sliding block 308. The inner spring 309 is compressed. Then the lowering plate 106 reaches above the sliding block 308 and returns to the initial position.
