Technical Field
[0001] This invention relates to the field of zinc alloy electroplating technology, specifically to an automated vertical lifting production line and intelligent detection system for electroplating zinc alloys. Background Technology
[0002] Zinc alloys are commonly used alloys made by adding elements such as aluminum, copper, and magnesium to zinc. They have excellent casting fluidity, formability, and moderate mechanical properties. They are cost-controllable, easy to die-cast, and widely used in hardware, auto parts, electronics, decorative structural parts, and appearance parts. They are a basic alloy material in light industry manufacturing and equipment supporting fields. They can quickly form complex components to meet the needs of large-scale production and basic structural functions in multiple fields.
[0003] Zinc alloy electroplating is a core surface modification process for zinc alloy products. It forms a protective and decorative coating on the zinc alloy substrate through electrochemical deposition, effectively solving the problems of easy oxidation, poor corrosion resistance, and insufficient surface texture of zinc alloys. It improves wear resistance, weather resistance, and aesthetics, and connects the forming of zinc alloy substrates with the application of finished products. It is a key post-processing step to optimize the performance of zinc alloy products, expand applicable scenarios, and ensure product durability and appearance quality.
[0004] Existing technologies often involve manually attaching hangers to production line hooks to mount products. This method relies on manual alignment and attachment of the hangers, fixing them to the production line's transmission mechanism. While suitable for small-batch production, it has significant drawbacks: low efficiency, high labor intensity, susceptibility to hanger misalignment and detachment, poor alignment accuracy affecting electroplating quality, safety hazards associated with manual operation, and unsuitability for large-scale continuous production. Therefore, this paper proposes an automated vertical lifting production line for electroplating zinc alloys. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an automated vertical lifting production line and intelligent inspection system for electroplated zinc alloys, which can automatically hang the hangers on the hooks of the production line, thus solving the problems in the background technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic vertical lifting production line for electroplating zinc alloy, comprising a main frame, a horizontal moving mechanism disposed on the main frame, an electroplating tank disposed on the main frame, a vertical lifting mechanism disposed on the horizontal moving mechanism, and a feeding mechanism disposed on the vertical lifting mechanism. The feeding mechanism includes a hanging frame and a support frame. Conical blocks are fixed at both ends of the hanging frame. A symmetrical rotating plate is rotatably connected to the support frame. Symmetrically arranged trapezoidal blocks are fixed to the support frame. The bottom of the trapezoidal blocks contacts the top of the rotating plate. The feeding mechanism also includes an elastic element rotatably connected to the rotating plate and the support frame.
[0007] Furthermore, the horizontal moving mechanism includes a rack and a sliding seat. The rack is fixed on the main frame, and the sliding seat is mounted on the main frame via a slide rail. A first motor is fixed on the sliding seat, and a gear is fixed at the output end of the first motor. The gear meshes with the rack.
[0008] Through the above scheme, the main frame provides movement guidance for the sliding seat via a slide rail, limiting its displacement trajectory. The first motor, as the power output component, drives the gears. The gears mesh with the rack to transmit power, causing the sliding seat to reciprocate along the slide rail. During operation, the first motor starts and outputs driving force, causing the gears and rack to mesh and transmit power, converting the power into linear displacement of the sliding seat. This enables controllable movement of the sliding seat on the main frame, providing support for the position adjustment of subsequent components.
[0009] Furthermore, the electroplating tank includes a pretreatment tank, a main electroplating tank, and a posttreatment tank, which are fixed on the main frame.
[0010] The above scheme provides a mounting platform for the pretreatment tank, main electroplating tank, and posttreatment tank, which are arranged in an orderly manner to form a complete processing flow architecture. The pretreatment tank is responsible for product pretreatment, the main electroplating tank undertakes the electroplating operation, and the posttreatment tank performs the post-processing steps. During operation, the product is processed sequentially through the pretreatment tank, main electroplating tank, and posttreatment tank.
[0011] Furthermore, the pretreatment tank includes an oil removal tank, an acid pickling tank, an activation tank, and a multi-stage water washing tank; the electroplating main tank includes a pre-plating tank, a main plating tank, and a multi-stage water washing tank; and the post-treatment tank includes a passivation tank, a sealing tank, a water washing tank, a drying tank, and a multi-stage water washing tank.
[0012] The above scheme involves several steps: In the pretreatment tank, the degreasing tank removes oil stains from the product surface; the pickling tank dissolves the oxide layer; the activation tank enhances surface activity; and the multi-stage rinsing tank prevents cross-contamination of chemicals. In the main electroplating tank, the pre-plating tank prepares the substrate to ensure coating adhesion; the main plating tank achieves the deposition of the target coating; and the rinsing tank cleans residual plating solution. In the post-treatment tank, the passivation tank enhances the corrosion resistance of the coating; the sealing tank improves surface smoothness; the rinsing tank purifies residual chemicals; and the drying tank removes moisture.
[0013] Furthermore, the vertical lifting mechanism includes a mounting plate, which is fixed on a sliding seat. A second motor is fixed on the mounting plate, and a lead screw module is fixed to the output end of the second motor. A connecting frame is fixed on the lead screw module.
[0014] Through the above scheme, the sliding seat can drive the mounting plate to move synchronously, realizing the position adjustment of the vertical lifting mechanism. The mounting plate provides a fixed base for the second motor, which acts as a power source to output driving force, driving the lead screw module to move. The lead screw module transmits power and adjusts the height of the connecting frame. During operation, after the second motor starts, it drives the connecting frame to move through the lead screw module, which, in conjunction with the movement of the sliding seat, enables the connecting frame to operate in the designated area.
[0015] Furthermore, the elastic element is an elastic telescopic rod.
[0016] The above scheme uses an elastic element to reset the rotating plate after it has rotated.
[0017] Furthermore, the lower end of the cone block is configured as an inclined guide surface, which is inclined outward along the length of the bracket; the end of the rotating plate near the cone block is machined into an arc-shaped fitting surface, which is completely fitted with the outer circumferential surface of the cone block; the elastic element is arranged horizontally, its axis is parallel to the rotation plane of the rotating plate, and the extension and retraction direction of the elastic element is tangent to the rotation trajectory of the rotating plate.
[0018] Furthermore, the rotating plate is rotatably connected to the support frame via a pin, and an arc-shaped groove adapted to the cone block is opened in the middle of the rotating plate; the inclined surface of the trapezoidal block faces the end of the rotating plate, and the two ends of the elastic element are respectively hinged to the back of the rotating plate and the side wall of the support frame. When the elastic element is in its natural state, the top surface of the rotating plate is in close contact with the bottom surface of the trapezoidal block.
[0019] Furthermore, the bottom of the sliding seat is provided with a sliding groove that matches the slide rail. The rack is fixed along the length of the main frame. The gear is sleeved and fixed to the end of the output shaft of the first motor. The gear and the rack mesh on the full tooth surface. The mounting plate is fixed to the top surface of the sliding seat by bolts. The lead screw module is set vertically. Its upper end is coaxially fixed to the output end of the second motor, and its lower end is threadedly connected to the top of the connecting frame.
[0020] Furthermore, the pretreatment tank, electroplating main tank, and posttreatment tank are arranged sequentially along the length of the main frame, with an operating gap reserved between adjacent tanks; the degreasing tank, pickling tank, activation tank, and multi-stage water washing tank of the pretreatment tank are arranged linearly, the pre-plating tank, main plating tank, and multi-stage water washing tank of the electroplating main tank are connected sequentially, and the passivation tank, sealing tank, water washing tank, and drying tank of the posttreatment tank are arranged in the process flow order, and the bottom of all tanks are welded and fixed to the crossbeams of the main frame.
[0021] Furthermore, an intelligent inspection system for an automated vertical lifting production line for electroplated zinc alloys includes the following steps:
[0022] Step 1: After the hanging bracket of the feeding mechanism carries the workpiece, the position sensor detects the contact status between the hanging bracket and the support frame to confirm that the hanging bracket is installed in place;
[0023] Step 2: When the horizontal moving mechanism drives the vertical lifting mechanism to move, the horizontal position data of the sliding seat is collected in real time by the displacement sensor to ensure that the bracket is accurately aligned with the corresponding position of the electroplating tank.
[0024] Step 3: After the vertical lifting mechanism drives the hanging rack to be immersed in the electroplating tank, the output parameters of the high-frequency power supply are collected through current sensors and voltage sensors, and the electric field distribution in the main electroplating tank is monitored synchronously.
[0025] Step 4: The temperature of the plating solution in the electroplating tank is detected by a temperature sensor, and the data is fed back to the controller in real time, which in turn activates the steam heating pipe to adjust the temperature of the solution to the set range.
[0026] Furthermore, it also includes the following steps:
[0027] Step 5: Collect the bath parameters of the pretreatment tank, main electroplating tank and posttreatment tank in real time through pH sensor and concentration sensor, and combine them with the flow sensor data of the filter to determine the purity of the bath solution;
[0028] Step Six: When the tank liquid parameters are detected to deviate from the preset threshold, the controller triggers the replenishment device to replenish the corresponding reagent, and at the same time controls the filter to increase the filtration frequency; when the tank liquid contamination exceeds the standard, the linkage drainage system discharges the tank liquid into the standby tank, and switches the qualified tank liquid in the standby tank to the working tank.
[0029] Furthermore, it also includes the following steps:
[0030] Step 7: After the workpiece is electroplated and passivated and sealed in the post-treatment tank, the coating thickness on the workpiece surface is detected by a coating thickness sensor, and coating appearance defects are identified by a vision inspection module.
[0031] Step 8: If the coating thickness is found to be below standard, the controller adjusts the output power of the high-frequency power supply and the immersion time of the workpiece in the main electroplating tank; if an appearance defect is detected, the linkage sorting mechanism transfers the unqualified workpiece to the rework area, and the qualified workpiece enters the drying tank for drying.
[0032] Furthermore, it also includes the following steps:
[0033] Step 9: Detect the exhaust gas parameters at the inlet and outlet of the exhaust gas treatment tower using exhaust gas concentration sensors, and simultaneously monitor the operating speed of the fan and the flow rate data of the spray system;
[0034] Step 10: When the exhaust gas concentration exceeds the emission standard, the controller increases the fan speed and the power of the circulating pump of the spray system to enhance the exhaust gas washing effect; when the fan is detected to be operating abnormally, the alarm device is triggered and the electroplating process of the production line is cut off. Operation is resumed after the fault is cleared; all detection data are stored in the controller in real time to form a production detection log.
[0035] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:
[0036] This electroplating zinc alloy vertical lifting automatic production line controls the lifting and lowering of the support frame through a vertical lifting mechanism. During the descent of the support frame, the rotating plate is limited by the cone block and will rotate on the support frame. After the rotating plate moves below the cone block, the rotating plate resets. At this time, the support frame rises. Because the trapezoidal block limits the rotating plate, the support frame can lift the hanger and the cone block through the rotating plate, realizing the automatic hanging of the hanger on the hook of the connecting frame.

The lead screw module 503 transmits power and adjusts the height of the connecting frame 504. During operation, after the second motor 502 starts, it drives the connecting frame 504 through the lead screw module 503, coordinating with the movement of the sliding seat 402 to enable the connecting frame 504 to operate within a designated area.

The two ends of the elastic member 206 are respectively hinged to the back of the rotating plate 204 and the side wall of the support frame 202. When the elastic member 206 is in its natural state, the top surface of the rotating plate 204 is in close contact with the bottom surface of the trapezoidal block 205.

[0054] This invention also discloses an intelligent inspection system for an automated vertical lifting production line for electroplated zinc alloys, comprising the following steps:
[0055] Step 1: After the hanging frame 201 of the feeding mechanism 2 carries the workpiece, the position sensor detects the contact status between the hanging frame 201 and the support frame 202 to confirm that the hanging frame 201 is installed in place.
[0056] Step 2: When the horizontal moving mechanism 4 drives the vertical lifting mechanism 5 to move, the horizontal position data of the sliding seat 402 is collected in real time by the displacement sensor to ensure that the hanging bracket 201 is accurately aligned with the corresponding position of the electroplating tank 3.
[0057] Step 3: After the vertical lifting mechanism 5 drives the hanging bracket 201 to be immersed in the electroplating tank 3, the output parameters of the high-frequency power supply are collected through the current sensor and voltage sensor, and the electric field distribution in the main electroplating tank 302 is monitored synchronously.
[0058] Step 4: The temperature of the plating solution in the electroplating tank 3 is detected by the temperature sensor, and the data is fed back to the controller in real time, which in turn activates the steam heating tube to adjust the temperature of the solution to the set range.
[0059] Step 5: Collect the bath parameters of the pretreatment tank 301, electroplating main tank 302, and posttreatment tank 303 in real time using pH and concentration sensors, and combine them with the flow sensor data of the filter to determine the purity of the bath solution.
[0060] Step Six: When the tank solution parameters are detected to deviate from the preset threshold, the controller triggers the replenishment device to replenish the corresponding reagent, and at the same time controls the filter to increase the filtration frequency; when the tank solution contamination exceeds the standard, the linkage drainage system discharges the tank solution into the standby tank, and switches the qualified tank solution in the standby tank to the working tank.
[0061] Step 7: After the workpiece is electroplated and passivated and sealed in post-treatment tank 303, the coating thickness on the workpiece surface is detected by a coating thickness sensor, and coating appearance defects are identified by a vision inspection module.
[0062] Step 8: If the coating thickness is found to be below standard, the controller adjusts the output power of the high-frequency power supply and the immersion time of the workpiece in the main electroplating tank 302; if an appearance defect is detected, the linkage sorting mechanism transfers the unqualified workpiece to the rework area, and the qualified workpiece enters the drying tank for drying.
[0063] Step 9: Detect the exhaust gas parameters at the inlet and outlet of the exhaust gas treatment tower using exhaust gas concentration sensors, and simultaneously monitor the operating speed of the fan and the flow rate data of the spray system;
[0064] Step 10: When the exhaust gas concentration exceeds the emission standard, the controller increases the fan speed and the power of the circulating pump of the spray system to enhance the exhaust gas washing effect; when the fan is detected to be operating abnormally, the alarm device is triggered and the electroplating process of the production line is cut off. Operation is resumed after the fault is cleared; all detection data are stored in the controller in real time to form a production detection log.
[0065] The working principle of the above embodiments is as follows:
[0066] The staff hangs the product to be electroplated on the hanger 201, and then places the hanger 201 on the right end of the main frame 1. The second motor 502 starts and controls the lead screw module 503 to start, which in turn drives the connecting frame 504 to rise and fall. The rise and fall of the connecting frame 504 will drive the support frame 202 to rise and fall.
[0067] During the descent of the support frame 202, the rotating plate 204 will rotate on the support frame 202 due to the limiting effect of the cone block 203. After the rotating plate 204 moves below the cone block 203, the rotating plate 204 will reset. At this time, the support frame 202 will rise. Since the trapezoidal block 205 limits the rotating plate 204, the support frame 202 can raise the hanger 201 and the cone block 203 through the rotating plate 204, so as to automatically hang the hanger 201 on the hook of the connecting frame 504.
[0068] The first motor 403 drives the gear 404 to rotate. The gear 404 meshes with the rack 401, so the sliding seat 402 will slide horizontally, thereby driving the mounting plate 501, the second motor 502, the hanger 201 and other parts to move horizontally, and moving the hanger 201 to the corresponding working area of the pretreatment tank 301, the electroplating main tank 302 and the posttreatment tank 303 to realize the electroplating work of the product.

10. An intelligent detection system for an automated vertical lifting production line for electroplating zinc alloys, applied to the automated vertical lifting production line for electroplating zinc alloys as described in any one of claims 1-9, characterized in that, Includes the following steps: Step 1: After the hanging bracket (201) of the feeding mechanism (2) carries the workpiece, the position sensor detects the contact state between the hanging bracket (201) and the support frame (202) to confirm that the hanging bracket (201) is installed in place; Step 2: When the horizontal moving mechanism (4) drives the vertical lifting mechanism (5) to move, the horizontal position data of the sliding seat (402) is collected in real time by the displacement sensor; Step 3: After the vertical lifting mechanism (5) drives the hanging bracket (201) to be immersed in the electroplating tank (3), the output parameters of the high-frequency power supply are collected by the current sensor and voltage sensor, and the electric field distribution in the main electroplating tank (302) is monitored synchronously. Step 4: The temperature of the plating solution in the electroplating tank (3) is detected by the temperature sensor, and the data is fed back to the controller in real time. The steam heating pipe is linked to adjust the temperature of the plating solution to the set range. Step 5: Collect the bath parameters of the pretreatment tank (301), electroplating main tank (302), and posttreatment tank (303) in real time using pH sensor and concentration sensor, and combine them with the flow sensor data of the filter to determine the purity of the bath solution; Step Six: When the tank solution parameters are detected to deviate from the preset threshold, the controller triggers the replenishment device to replenish the corresponding reagent, and at the same time controls the filter to increase the filtration frequency; when the tank solution contamination exceeds the standard, the linkage drainage system discharges the tank solution into the standby tank, and switches the qualified tank solution in the standby tank to the working tank. Step 7: After the workpiece is electroplated and passivated and sealed in the post-treatment tank (303), the thickness of the coating on the workpiece surface is detected by the coating thickness sensor, and the appearance defects of the coating are identified by the visual inspection module. Step 8: If the coating thickness is found to be below standard, the controller adjusts the output power of the high-frequency power supply and the immersion time of the workpiece in the electroplating main tank (302); if an appearance defect is detected, the linkage sorting mechanism transfers the unqualified workpiece to the rework area, and the qualified workpiece enters the drying tank for drying. Step 9: Detect the exhaust gas parameters at the inlet and outlet of the exhaust gas treatment tower using exhaust gas concentration sensors, and simultaneously monitor the operating speed of the fan and the flow rate data of the spray system; Step 10: When the exhaust gas concentration exceeds the emission standard, the controller increases the fan speed and the power of the circulating pump of the spray system to enhance the exhaust gas washing effect; when the fan is detected to be operating abnormally, the alarm device is triggered and the electroplating process of the production line is cut off. Operation is resumed after the fault is cleared; all detection data are stored in the controller in real time to form a production detection log.
