Description

Technical Field

[0001] The present invention relates to the technical field of fire cabinet electroplating, and in particular to an electroplating device for processing fire cabinets. Background Art

[0002] Electroplating refers to a surface processing method in which the base metal to be plated is used as the cathode in a salt solution containing the metal to be plated. Through electrolysis, the cations of the metal to be plated in the plating solution are deposited on the surface of the base metal to form a coating. The performance of the coating is different from that of the base metal and has new characteristics. According to the function of the coating, it can be divided into protective coating, decorative coating and other functional coatings.

[0003] In the existing technology, when a common fire cabinet electroplating device is used for fire cabinet electroplating, the plating solution in the electroplating tank needs to flow so that the metal ions consumed near the cathode can be replenished in time and the concentration polarization effect of the cathode can be reduced. At the same time, the upper limit of the allowable cathode current density can be increased, and a fine and dense plating layer can be obtained at a higher current density and higher current efficiency. However, it will also stir various solid impurities and residues in the electroplating solution, so the flowing electroplating solution needs to be filtered regularly or continuously. However, the existing device has the following problems for filtering the electroplating solution: (1) the fixed filter screen is easy to be clogged during continuous filtration; (2) it is more troublesome to clean the solid impurities and residues on the filter screen.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

DETAILED DESCRIPTION

[0043] The technical solutions 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 only part of the embodiments of the present invention, rather than all the embodiments.

[0044] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0045] Reference Figure 1-9 A plating device for processing fire cabinets, comprising a bracket 1, a conveying device 3 provided on the upper portion of the bracket 1 for driving a cabinet body 2 to move, a workbench 4 located below the cabinet body 2, and an electroplating tank 5 provided in the middle of the workbench 4. A filter mechanism 6 for filtering the electroplating solution is provided at the front end of the electroplating tank 5;

[0046] The filtering mechanism 6 includes a filter box 61 provided at the front end of the electroplating tank 5 and a plurality of filter components provided in the filter box 61. The plurality of filter components are sequentially provided in the filter box 61 from top to bottom. A liquid inlet is provided at the upper left end of the filter box 61, and a liquid outlet is provided at the lower right end of the filter box 61. A box door is detachably installed at the front end of the filter box 61, and a seal is provided between the box door and the filter box 61. Specifically, the box door can be opened to remove solid impurities or residues at the bottom of the filter box 61 from the filter box 61.

[0047] The filter assembly includes a conical filter cover 62 fixedly connected to the filter box 61, with the smaller end of the conical filter cover 62 facing upward. A plurality of fan-shaped grooves are provided around the conical filter cover 62, and fan-shaped filter screens 63 are provided in the plurality of fan-shaped grooves, each of which is rotatably provided by a first torsion spring shaft. The plurality of first torsion spring shafts are provided at the smaller end of the conical filter cover 62. Specifically, the fan-shaped filter screens 63 on the side of the conical filter cover 62 are tilted, so that most solid impurities and residues will accumulate on the end of the fan-shaped filter screen 63 away from the first torsion spring shaft, making it easier for the electroplating solution to fall from the non-accumulated area in the later stage and facilitating the collection of solid impurities and residues in the later stage.

[0048] The filter diameters of the fan-shaped filters 63 in the multiple filter assemblies decrease from top to bottom. Specifically, the electroplating liquid passes through the fan-shaped filters 63 in the filter assemblies from top to bottom, achieving multi-stage filtration of the electroplating liquid, leaving solid impurities and residues in the electroplating liquid on the fan-shaped filters 63. The filtered electroplating liquid enters the return pipe 51 from the liquid outlet pipe 53, and is then sprayed into the electroplating tank 5 from the multiple spray heads 52, achieving the flow of the electroplating liquid in the electroplating tank 5, so that the electroplating liquid contacts the cabinet 2 evenly, and preventing the solid impurities and residues in the electroplating liquid from reducing the bonding strength between the plating layer and the base metal, thereby preventing the plating layer from becoming rough, loose, and porous.

[0049] The bottoms of the multiple fan-shaped filter screens 63 in any group of filter components are in contact with one end of the knocking rod 64, and the ends of the multiple knocking rods 64 away from the fan-shaped filter screen 63 are rotatably connected to the bottom of the support plate 65 through the second torsion spring shaft. The top of the support plate 65 is fixedly connected to the bottom of the top of the conical filter cover 62, and the upper parts of the knocking rods 64 away from the end of the fan-shaped filter screen 63 are all in contact with the bottom ends of the trigger blocks 66. The tops of the multiple trigger blocks 66 are all mounted on the bottom ends of the fixed plates 67, and the middle parts of the fixed plates 67 are fixedly mounted on the surface of the rotating shaft 68. The rotating shaft 68 is rotatably set in the filter box 61, and the top of the filter box 61 is provided with a first motor for driving the rotating shaft 68. Specifically, starting the first motor drives the rotating shaft 68 to rotate, thereby driving the fixed plate 67 to rotate, so that the fixed plate The multiple trigger blocks 66 at the bottom end of 67 contact the upper parts of the multiple fixed rods 641 in turn. Specifically, when the trigger block 66 contacts the upper part of the fixed rod 641, the trigger block 66 will drive the rotation around the second torsion spring axis, so that the adjustment rod 643 knocks the fan-shaped filter 63; when the trigger block 66 is disengaged from the upper part of the fixed rod 641, the second torsion spring axis drives the fixed rod 641 to reset, so that the adjustment rod 643 is away from the fan-shaped filter 63, thereby causing the electroplating liquid and solid impurities or residue on the fan-shaped filter 63 to shake, preventing solid impurities or residue from blocking the filter holes of the fan-shaped filter 63, accelerating the flow of the electroplating liquid, and improving the efficiency of the electroplating liquid filtration. Here, the shaking range of the fan-shaped filter 63 when knocking is determined by the tension of the filter layer and the filter frame in the fan-shaped filter 63.

[0050] Furthermore, the knocking rod 64 includes a fixed rod 641 rotatably connected to the support plate 65, a second electric telescopic rod 642 provided at one end of the fixed rod 641 away from the support plate 65, and an adjusting rod 643 provided at the movable end of the second electric telescopic rod 642, the adjusting rod 643 contacts the bottom end of the fan-shaped filter 63, specifically, starting the second electric telescopic rod 642, so that the second electric telescopic rod 642 is shortened, driving the adjusting rod 643 close to the fixed rod 641, reducing the rotation range of the adjusting rod 643, further starting the first motor, driving the rotating shaft 68 to rotate, and then driving the multiple trigger blocks 66 to rotate through the fixed plate 67, so that the multiple trigger blocks 66 contact the fixed rod 641, similarly, when the trigger block 66 contacts the fixed rod 641 When the filter screen 63 is in contact with the filter housing 63, the filter housing 63 is moved away from the filter housing 63 by the second torsion spring shaft. When the filter screen 63 is in contact with the filter housing 63, the filter housing 63 is moved away from the filter housing 63 by the first torsion spring shaft. When the filter screen 63 is in contact with the filter housing 63, the filter housing 63 is moved away from the filter housing 63 by the second torsion spring shaft. When the filter screen 63 is in contact with the filter housing 63, the filter housing 63 is moved away from the filter housing 63 by the first torsion spring shaft.

[0051] Furthermore, the end of the fixed rod 641 away from the support plate 65 is connected to a guide sleeve 644 through a thread, and the end of the guide sleeve 644 away from the fixed rod 641 is slidably connected to the surface of the adjusting rod 643. The inner wall of the guide sleeve 644 is provided with a rubber ring that holds the adjusting rod 643 tightly. Specifically, through the provision of the guide sleeve 644, the movement of the adjusting rod 643 can be guided, and the stability of the adjusting rod 643 during the movement process can be improved. At the same time, the bearing capacity of the second electric telescopic rod 642 can be improved to avoid the bending of the second electric telescopic rod 642 when the high adjusting rod 643 contacts the fan-shaped filter 63. The provision of the rubber ring can provide a closed working environment for the second electric telescopic rod 642.

[0052] Furthermore, a limit plate 69 for adjusting the rotation angle of the multiple fan-shaped filter screens 63 is provided above the multiple knocking rods 64, and the ends of the multiple limit plates 69 away from the fan-shaped filter screens 63 are fixedly connected to the outer surface of the connecting ring 691, and the connecting ring 691 and the multiple support plates 65 are connected by sliding sleeves to slide up and down, and the connecting ring 691 and the bottom of the top of the conical filter cover 62 are connected by a first electric telescopic rod 692. Specifically, the positioning of the fan-shaped filter screen 63 is achieved by the fan-shaped groove, the first torsion spring shaft and the limit plate 69; start the first motor to drive the rotating shaft 68 to rotate, and then drive the multiple trigger blocks 66 to rotate through the fixed plate 67, so that the multiple trigger blocks 66 are in contact with the fixed rod 641. Similarly, when the trigger block 66 is in contact with the fixed rod 641 When in contact, the trigger block 66 will drive the fixed rod 641 to rotate around the second torsion spring axis, so that the adjusting rod 643 contacts the fan-shaped filter 63, driving the fan-shaped filter 63 to rotate around the first torsion spring axis, so that the fan-shaped filter 63 is away from the limit plate 69. When the trigger block 66 is disengaged from the fixed rod 641, the second torsion spring axis drives the fixed rod 641 to quickly reset, so that the adjusting rod 643 quickly moves away from the fan-shaped filter 63. At this time, under the action of the first torsion spring axis, the fan-shaped filter 63 is driven to rotate quickly and contact the limit plate 69. The impact force when the fan-shaped filter 63 contacts the limit plate 69 will cause the solid impurities or residue in the fan-shaped filter 63 to separate from the fan-shaped filter 63, thereby further accelerating the cleaning of the fan-shaped filter 63.

[0053] Furthermore, the trigger block 66 is a square plate, and one end of the square plate close to the rotation direction of the rotating shaft 68 is arc-shaped, which is convenient for contact with the fixed rod 641. Specifically, since the one end of the trigger block 66 close to the rotation direction of the rotating shaft 68 is arc-shaped, it is convenient for the trigger block 66 to contact with the fixed rod 641, and the other end of the trigger block 66 is a right-angled side, so the trigger block 66 can suddenly disengage from the fixed rod 641, allowing the fixed rod 641 to be quickly reset.

[0054] Furthermore, a mounting hole is provided in the middle of the top of the conical filter cover 62, and the mounting hole is connected to the rotating shaft 68 via a sealed bearing. Specifically, the setting of the sealed bearing prevents unfiltered electroplating liquid from falling directly onto the bottom of the filter box 61.

[0055] The inner walls of the plurality of sector-shaped grooves are provided with inwardly inclined material guide slopes. Specifically, the setting of the material guide slopes can guide the electroplating solution and solid impurities or slag in a mirror-like manner.

[0056] Furthermore, the upper left end of the filter box 61 is connected to a liquid inlet pipe connected to the liquid inlet port, the end of the liquid inlet pipe away from the filter box 61 is connected to and communicated with the output end of the liquid pump, the input end of the liquid pump is communicated with the lower part of the electroplating tank 5 through the liquid extraction pipe, the liquid extraction pipe is connected to a liquid replenishment pipe through a three-way valve, the liquid replenishment pipe is communicated with an external electroplating liquid storage device, and a first valve is provided at one end of the liquid replenishment pipe close to the three-way valve, and a second valve is provided on the liquid extraction pipe between the three-way valve and the electroplating tank 5. Specifically, the second valve on the liquid extraction pipe is opened, and the first valve on the liquid replenishment pipe is closed, and then the liquid extraction pump is started to introduce the electroplating liquid from the lower part of the electroplating tank 5 into the filter box 61; when it is necessary to replenish the electroplating liquid to the electroplating tank 5, the second valve is closed and the first valve is opened, and the liquid extraction pump is started to introduce the electroplating liquid in the external electroplating liquid storage device into the electroplating tank 5;

[0057] Furthermore, a liquid outlet pipe 53 connected to the liquid outlet is provided at the lower right end of the filter box 61, and the end of the liquid outlet pipe 53 away from the filter box 61 is connected to and communicated with the loop pipe 51 at the upper end of the electroplating pool 5, and the end of the loop pipe 51 away from the inner wall of the electroplating pool 5 is detachably installed with multiple spray heads 52, and the loop pipe 51 is fixedly connected to the inner wall of the electroplating pool 5 through multiple Ω rings 54; the multiple spray heads 52 are arranged obliquely downward, specifically, the filtered electroplating liquid enters the loop pipe 51 from the liquid outlet pipe 53, and then is sprayed into the electroplating pool 5 from the multiple spray heads 52, thereby realizing the flow of the electroplating liquid in the electroplating pool 5, so that the electroplating liquid is evenly in contact with the cabinet 2, avoiding the reduction of the bonding strength between the plating layer and the base metal due to solid impurities and slag in the electroplating liquid, making the plating layer rough, loose and porous.

[0058] Furthermore, the conveying device 3 includes a hook 31 for hanging the cabinet 2 and a third electric telescopic rod 32 arranged at the top of the hook 31. The tops of the multiple third electric telescopic rods 32 are slidably connected to the bottom end of the installation box through the mounting block. The installation box is fixedly arranged on the top of the bracket 1. The bottom end of the installation box is provided with a return chute for sliding multiple mounting blocks. A conveyor belt 33 is rotatably arranged in the installation box. Multiple mounting blocks are evenly slidably and fixedly connected to the bottom end of the conveyor belt 33. The top end of the installation box is provided with a second motor for driving the conveyor belt 33. Specifically, the cabinet 2 is first hung on the hook 31 at one end of the workbench 4; then the motor is started. The second motor drives the conveyor belt 33 to rotate, and then drives the hooks 31 at the bottom of the multiple third electric telescopic rods 32 to approach the middle of the workbench 4 through the mounting block until the cabinet 2 on the hooks 31 is located above the electroplating tank 5, and the second motor is stopped to prevent the cabinet 2 from moving. Then, the third electric telescopic rod 32 is started to extend, thereby driving the cabinet 2 to move downward, so that the cabinet 2 is located in the electroplating tank 5 and contacts the electroplating liquid. When the electroplating of the cabinet 2 is completed, the third electric telescopic rod 32 is started to reset, and the cabinet 2 is lifted from the electroplating tank 5. Further, the second motor is started to transport the electroplated cabinet 2 to the next process.

[0059] Working principle: When in use, first hang the cabinet 2 on the hook 31 at one end of the workbench 4; then start the second motor to drive the conveyor belt 33 to rotate, and then drive the hooks 31 at the bottom of the multiple third electric telescopic rods 32 to move close to the middle of the workbench 4 through the mounting block until the cabinet 2 on the hook 31 is above the electroplating tank 5, and then stop the second motor so that the cabinet 2 no longer moves; then start the third electric telescopic rod 32 to extend it, and then drive the cabinet 2 downward so that the cabinet 2 is located in the electroplating tank 5 and contacts the electroplating liquid; when the electroplating of the cabinet 2 is completed, start the third electric telescopic rod 32 to reset, lift the cabinet 2 from the electroplating tank 5, and further start the second motor to convey the electroplated cabinet 2 to the next process;

[0060] During the electroplating process of the cabinet 2, the second valve on the liquid extraction pipe is opened, and the first valve on the liquid replenishing pipe is closed, and then the liquid extraction pump is started to guide the electrolytic liquid from the lower part of the electroplating tank 5 into the filter box 61. At this time, the electroplating liquid passes through the fan-shaped filter 63 in the filter assembly from top to bottom, realizing multi-stage filtration of the electroplating liquid, leaving solid impurities and residues in the electroplating liquid on the fan-shaped filter 63, and the filtered electroplating liquid enters the return pipe 51 from the liquid outlet pipe 53, and is then sprayed into the electroplating tank 5 from the multiple spray heads 52, realizing the flow of the electroplating liquid in the electroplating tank 5, so that the electroplating liquid is evenly contacted with the cabinet 2, and it is prevented that the solid impurities and residues in the electroplating liquid reduce the bonding strength between the plating layer and the base metal, making the plating layer rough, loose, and porous;

[0061] When the electroplating solution passes through the fan-shaped filter 63 in the filter assembly from top to bottom, the first motor is started to drive the rotating shaft 68 to rotate, thereby driving the fixed plate 67 to rotate, so that the multiple trigger blocks 66 at the bottom end of the fixed plate 67 sequentially contact the upper parts of the multiple fixed rods 641. Specifically, when the trigger block 66 contacts the upper part of the fixed rod 641, the trigger block 66 will drive the rotation around the second torsion spring axis, so that the adjustment rod 643 knocks the fan-shaped filter 63; when the trigger block 66 When the second torsion spring shaft is disengaged from the upper portion of the fixing rod 641, the fixing rod 641 is reset, so that the adjusting rod 643 moves away from the fan-shaped filter 63, thereby causing the electroplating liquid and solid impurities or residue on the fan-shaped filter 63 to vibrate, thereby preventing the solid impurities or residue from blocking the filter holes of the fan-shaped filter 63, accelerating the flow of the electroplating liquid, and improving the efficiency of the electroplating liquid filtration. Here, the vibration range of the fan-shaped filter 63 when struck is determined by the tension between the filter layer and the filter frame in the fan-shaped filter 63;

[0062] Since the end of the trigger block 66 close to the rotation direction of the rotating shaft 68 is arc-shaped, it is easy for the trigger block 66 to contact the fixed rod 641. The other end of the trigger block 66 is a right-angled side, so the trigger block 66 can suddenly separate from the fixed rod 641, allowing the fixed rod 641 to be quickly reset.

[0063] When it is necessary to clean the solid impurities or residue on the fan-shaped filter 63, the liquid extraction pump is turned off, and the electroplating liquid in the filter box 61 is completely drained. Furthermore, the first electric telescopic rod 692 is started to drive the connecting ring 691 to move downward, so that the multiple limit plates 69 move downward. At this time, under the action of the multiple first torsion spring shafts, the multiple fan-shaped filter screens 63 rotate and move downward along with the limit plates 69. At this time, a gap appears between the end of the fan-shaped filter screen 63 away from the first torsion spring shaft and the fan-shaped groove, and the tilt angle of the fan-shaped filter screen 63 will be larger, thereby facilitating the solid impurities or residue on the fan-shaped filter screen 63 to slide down until the solid impurities or residue fall to the bottom of the filter box 61.

[0064] Among them, when solid impurities or residues on the fan-shaped filter screen 63 slide down, the second electric telescopic rod 642 is started, so that the second electric telescopic rod 642 is shortened, driving the adjusting rod 643 to approach the fixed rod 641, reducing the rotation range of the adjusting rod 643; further, the first motor is started to drive the rotating shaft 68 to rotate, and then drive the multiple trigger blocks 66 to rotate through the fixed plate 67, so that the multiple trigger blocks 66 are in contact with the fixed rod 641. Similarly, when the trigger block 66 is in contact with the fixed rod 641, the trigger block 66 will drive the fixed rod 641 to rotate around the second torsion spring axis, so that the adjusting rod 643 is in contact with the fan-shaped filter screen 63, driving the fan-shaped filter screen 63 to rotate around the first The torsion spring shaft rotates, causing the fan-shaped filter 63 to move away from the limit plate 69. When the trigger block 66 is disengaged from the fixing rod 641, the second torsion spring shaft drives the fixing rod 641 to quickly return to its original position, causing the adjustment rod 643 to quickly move away from the fan-shaped filter 63. At this time, under the action of the first torsion spring shaft, the fan-shaped filter 63 is driven to rotate quickly and contact the limit plate 69. The impact force when the fan-shaped filter 63 contacts the limit plate 69 will cause the solid impurities or residues in the fan-shaped filter 63 to separate from the fan-shaped filter 63, thereby further accelerating the cleaning of the fan-shaped filter 63. Furthermore, the box door is opened to remove the solid impurities or residues at the bottom of the filter box 61 from the filter box 61.

[0065] When the electroplating bath 5 needs to be replenished with electroplating liquid, the second valve is closed and the first valve is opened, and the liquid pump is started to introduce the electroplating liquid in the external electroplating liquid storage device into the electroplating bath 5 .
