DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present invention provides a new energy vehicle parts silver plating equipment, exemplarily, such as Figure 1 and Figure 2 As shown, it comprises a working box 100, a sealing door 110 is provided on the side wall of the working box 100, and a material transport unit 300 is provided at the center of the top inner wall of the working box 100. The material transport unit 300 is used to transport batches of parts in sequence.

[0034] A silver plating unit 400 is installed at the center of the inner wall at the bottom of the working box 100, and the bottom of the material transport unit 300 movably extends into the cavity of the silver plating unit 400. The silver plating unit 400 is used to perform silver plating on parts.

[0035] Specifically, a drying component 200 is installed on the inner wall of the working box 100. The drying component 200 is used to quickly dry and dehydrate the parts separated from the silver plating unit 400.

[0036] Preferably, a control component 500 is installed on the outer wall of the working box 100, and the control component 500 is electrically connected to the material transport unit 300 and the silver plating unit 400. The control component 500 is used to control the working state of the material transport unit 300 and the silver plating unit 400.

[0037] For example, Figure 3 As shown, the material transport unit 300 includes a first electric push rod 310, which is installed at the center of the top inner wall of the working box 100. The bottom of the first electric push rod 310 is connected to a lifting frame 320 in a transmission manner, and a servo motor 330 is installed on one side wall of the lifting frame 320. Two groups of chains 340 are symmetrically arranged in the lifting frame 320 with its own vertical center line as the center, and both groups of chains 340 are connected to the servo motor 330 in a transmission manner. The chains 340 are arranged vertically.

[0038] Exemplarily, a plurality of groups of crossbars 350 are arranged at equal intervals along their own paths between the two groups of chains 340, and the two ends of the crossbars 350 are respectively installed on the two groups of chains 340. A vertical rod 360 is hinged on the crossbar 350, and a material lifting mechanism 370 is installed at the bottom of the vertical rod 360.

[0039] For example, Figure 4 and Figure 5 As shown, the material lifting mechanism 370 includes a loading barrel 371, which is installed at the bottom of the vertical pole 360 ​​and is a grid-like structure. A central through slot 373 is provided at the center of the bottom of the loading barrel 371, and a net tower 374 is installed on the central through slot 373. The net tower 374 is a truncated cone structure, and the top diameter is smaller than the bottom diameter. The net tower 374 is a grid-like structure. A loading door 372 is movably installed on the loading barrel 371.

[0040] First, the batch of parts are placed in each assembly barrel 371 respectively. After completion, the loading door 372 is closed, and then the first electric push rod 310 is started, and the lifting frame 320 and each assembly barrel 371 are driven to descend by the first electric push rod 310 until the bottom assembly barrel 371 can be completely immersed in the cavity of the silver plating unit 400. Then the servo motor 330 is turned on, and the two groups of chains 340 are driven to rotate by the servo motor 330, and the chains 340 drive each assembly barrel 371 to immerse in and leave the cavity of the silver plating unit 400 at a uniform speed in turn, thereby realizing the automated batch operation of parts. When the chain 340 drives the silver-plated parts to leave the cavity of the silver plating unit 400, the drying component 200 on the side wall of the working box 100 is used to quickly dry the parts, further improving the degree of automation. In addition, since the loading barrel 371 is a grid-like structure, the silver ions in the electroplating solution can act on the parts from all directions, and the silver plating effect is also improved without manual operation. When the silver plating of the components in each assembly barrel 371 is completed, the first electric push rod 310 is started, and the lifting frame 320 is driven to rise by the first electric push rod 310 until the bottom assembly barrel 371 is completely separated from the silver plating unit 400.

[0041] The batch of parts are placed in each group of material lifting mechanisms 370, and the chains 340 drive each group of material lifting mechanisms 370 to enter and leave the cavity of the silver plating unit 400 in sequence, so as to realize the automatic batch silver plating operation, and the parts can be silver-plated twice or even multiple times without moving the parts, so that the workers can always stay away from the electroplating solution without affecting the silver plating work, which not only improves the automation degree and work efficiency of the device, but also reduces the safety hazards. At the same time, the grid structure is used to allow the silver ions in the electroplating solution to act on the parts from all directions, thereby improving the silver plating effect.

[0042] By providing a central through slot 373 at the bottom of the charging barrel 371 and arranging a truncated cone-shaped net tower 374 on the central through slot 373, a batch of parts can be evenly laid on the inner wall of the bottom of the charging barrel 371 along the side wall of the net tower 374 after entering the charging barrel 371, thereby reducing the probability of accumulation. At the same time, the plating liquid can also enter the net tower 374 through the central through slot 373, and then enter the charging barrel 371 from the net tower 374, further increasing the contact area between the parts and the plating liquid, and also making the silver plating more balanced.

[0043] For example, Figure 6 and Figure 7 As shown, the silver-plating unit 400 includes a bottom cylinder 410, and the bottom cylinder 410 is installed at the center of the bottom inner wall of the working box 100. A silver-plating pool 420 is opened at the center of the top of the bottom cylinder 410, and each group of the material lifting mechanism 370 is movably extended into the silver-plating pool 420. A plurality of groups of top grooves 411 are distributed in a circular array around the silver-plating pool 420, and anti-overflow grooves 412 are arranged around the top opening of the top grooves 411, and the anti-overflow grooves 412 are open structures near the side of the silver-plating pool 420. A liquid baffle plate 413 is provided at the edge of one side of the anti-overflow groove 412 away from the silver-plating pool 420, and the top cross-section of the liquid baffle plate 413 is a fan-shaped structure. A liquid flow hole 421 is provided on a side wall of each group of the top grooves 411 near the silver-plating pool 420, and each group of the top grooves 411 is connected to the silver-plating pool 420 through a corresponding group of liquid flow holes 421.

[0044] For example, Figure 8 As shown, a second electric push rod 430 is installed vertically at the bottom center of the top groove 411, and a ventilation groove is provided on one side of the second electric push rod 430. A lifting block 440 is connected to the top of the second electric push rod 430 in a transmission manner. A sealing ring 441 is sleeved on the side walls around the lifting block 440, and the outer wall of the sealing ring 441 is slidably fitted with the inner wall around the top groove 411. And the end of the liquid flow hole 421 close to the top groove 411 is movably fitted with the sealing ring 441. A silver rod fixing component 442 is provided at the top center of the lifting block 440, and a side stand plate 443 is provided on the side of the silver rod fixing component 442 away from the liquid flow hole 421, and a first one-way valve is provided on the side stand plate 443, and a first air blowing port 450 is provided on the output end of the first one-way valve, and the output end of the first air blowing port 450 faces the silver rod fixing component 442.

[0045] For example, Fig. 9 and Fig.10As shown, a conical bottom groove 460 is provided at the bottom of the silver-plating pool 420. The conical bottom groove 460 is a conical structure, and the end with a larger opening is vertically upward and connected with the silver-plating pool 420. A spiral air guide tube 470 is installed on the side wall of the conical bottom groove 460. The spiral air guide tube 470 is a conical structure and is installed on the conical bottom groove 460 along a spiral path. A plurality of groups of second one-way valves are arranged at equal intervals on the spiral air guide tube 470 along its own spiral path. The output end of the second one-way valve is connected with a second blowing port 471, and the output end of the second blowing port 471 is vertically upward.

[0046] First, each group of second electric push rods 430 is started, and each group of lifting blocks 440 is driven to rise by each group of second electric push rods 430 until the silver rod fixing parts 442 are separated from the top groove, and then each group of silver rods is fixed on each group of silver rod fixing parts 442, and then the lifting blocks 440 are controlled to descend. When the silver rods completely enter the top groove 411, the sealing ring 441 is also separated from the flow hole 421 at the same time, so that the plating solution can enter the top groove 411 and decompose the silver ions in the silver rods, and then the plating solution can be quickly circulated through the first blowing port 450, and the plating solution with silver ions can be more concentrated to move to the center of the silver plating pool 420. Then, each group of second blowing ports 471 is started, so that the plating solution with silver ions all moves upward, and acts from all sides and the bottom at the same time, so that the silver ions can act on the loading barrel 371 entering the silver plating pool 420.

[0047] By setting multiple groups of top grooves 411 and placing multiple groups of silver rods in each group of top grooves 411, when silver plating is performed, the flow holes 421 are used to realize the circulation of the plating solution. When one group of silver rods needs to be replaced, it is only necessary to control the second electric push rod 430 in the top groove 411 to drive the group of silver rods to rise, and use the sealing ring 441 to gradually discharge the plating solution in the top groove from the top of the top groove 411. When the silver rod is completely separated from the top groove 411, the sealing ring 441 just blocks the flow hole 421 to prevent the plating solution from entering the top groove 411. The replacement of the silver rod can be completed without stopping the silver plating work, thereby improving the continuity of the silver plating work.

[0048] Through each group of first air blowing ports 450, the electroplating solution with silver ions can be more concentratedly moved toward the center of the silver plating pool 420, and then through each group of second air blowing ports 471, the electroplating solution with silver ions can all move upward, acting from all sides and the bottom at the same time, so that the silver ions can be concentrated on the loading barrel 371 entering the silver plating pool 420, thereby accelerating the silver plating speed and improving the work efficiency. At the same time, each group of second air blowing ports 471 is arranged in a spiral path, so that the blown air flow is more concentrated on the loading barrel 371, so that the parts in the loading barrel 371 can roll quickly, thereby avoiding the silver plating dead corner caused by the stacking of parts.

[0049] The above embodiments have the following beneficial effects: 1. Place batches of parts in each group of material lifting mechanisms 370, and drive each group of material lifting mechanisms 370 to enter and leave the cavity of the silver plating unit 400 in sequence through the chain 340, so as to realize automated batch silver plating operation, and perform secondary or even multiple cycles of silver plating without moving the parts, so as to keep the workers away from the electroplating solution without affecting the silver plating work, which not only improves the automation degree and work efficiency of the device, but also reduces safety hazards. At the same time, the grid structure is used to allow the silver ions in the electroplating solution to act on the parts from all directions, thereby improving the silver plating effect.

[0050] 2. By providing a central through slot 373 at the bottom of the charging barrel 371 and arranging a truncated cone-shaped net tower 374 on the central through slot 373, a batch of parts can be evenly laid on the inner wall of the bottom of the charging barrel 371 along the side wall of the net tower 374 after entering the charging barrel 371, thereby reducing the probability of accumulation. At the same time, the plating solution can also enter the net tower 374 through the central through slot 373, and then enter the charging barrel 371 from the net tower 374, further increasing the contact area between the parts and the plating solution, and making the silver plating more balanced.

[0051] 3. By setting multiple groups of top grooves 411 and placing multiple groups of silver rods in each group of top grooves 411, when silver plating is performed, the flow hole 421 is used to realize the circulation of the plating liquid. When one group of silver rods needs to be replaced, it is only necessary to control the second electric push rod 430 in the top groove 411 to drive the group of silver rods to rise, and use the sealing ring 441 to gradually discharge the plating liquid in the top groove from the top of the top groove 411. When the silver rod is completely separated from the top groove 411, the sealing ring 441 just blocks the flow hole 421 to prevent the plating liquid from entering the top groove 411. The replacement of the silver rod can be completed without stopping the silver plating work, thereby improving the continuity of the silver plating work.

[0052] 4. Through each group of first air blowing ports 450, the electroplating solution with silver ions can be more concentratedly moved toward the center of the silver plating pool 420, and then through each group of second air blowing ports 471, the electroplating solution with silver ions can all move upward, acting from all sides and the bottom at the same time, so that the silver ions can be concentrated on the loading barrel 371 entering the silver plating pool 420, thereby accelerating the silver plating speed and improving the work efficiency. At the same time, each group of second air blowing ports 471 is arranged in a spiral path, so that the blown air flow acts more concentratedly on the loading barrel 371, so that the parts in the loading barrel 371 can roll quickly, thereby avoiding the silver plating dead corner caused by the stacking of parts.

[0053] Based on the above-mentioned silver-plating equipment for new energy vehicle parts, an embodiment of the present invention further proposes a silver-plating method for the silver-plating equipment. Exemplarily, the silver-plating method includes: Place the batches of parts in each assembly barrel and close the loading door when finished; Start the first electric push rod, and drive the lifting frame and each assembly barrel to descend through the first electric push rod until the lowest assembly barrel can be completely immersed in the cavity of the silver plating unit; Start two sets of chains, and the chains drive the assembled barrels to immerse into the cavity of the silver plating unit at a uniform speed in turn; Start the first blowing port of each group to make the electroplating solution with silver ions move toward the center of the silver plating pool; The second blowing ports of each group are activated to make the electroplating solution containing silver ions move upwards, and act from all sides and the bottom at the same time, so that the silver ions can be concentrated on the loading barrel entering the silver plating pool; When the chain drives the silver-plated parts out of the silver-plating pool, the drying parts are started to quickly dry the parts.
