Description

Technical Field

[0001] The present application relates to the technical field of shell surface coating, and in particular to a coating device based on shell surface treatment. Background Art

[0002] Electroplating involves depositing metal ions from an electrolyte solution onto the cathode surface of a workpiece under the influence of a direct current (DC) electric field. This process, based on ion redox reactions, aims to alter the surface properties of solid materials or create metals with specific compositions and properties.

[0003] In the electroplating process for electronic product housings, a common practice is to arrange and assemble multiple housings on a single frame. The gantry crane in the electroplating workshop then collaborates with a computer system to automatically immerse the frame with the housings in the electroplating bath to complete the electroplating. Although gantry cranes are renowned for their lifting and handling capabilities, automated operation, and high safety performance in electroplating production lines, they still have some shortcomings in actual application:

[0004] Operational Complexity: Gantry crane operation requires a high level of professional skills and experience. Improper operation can lead to equipment failure or safety accidents. In addition, the complex control system requires operators to undergo professional training to master it, which increases the difficulty of personnel training and management.

[0005] Difficult maintenance: The metal structure and electrical system of the gantry crane require regular maintenance and inspection to ensure its stability and reliability. However, due to its large size and complex structure, the maintenance process is relatively difficult and requires specialized maintenance personnel and equipment, which increases maintenance costs and downtime.

[0006] Limited adaptability and flexibility: Gantry cranes are often designed and manufactured for specific electroplating production lines, which limits their adaptability and flexibility. Changes in the process or workpieces of an electroplating line may require the gantry crane to be replaced or modified, increasing production costs and potentially extending line adjustment time, impacting productivity.

[0007] Furthermore, the housing is immersed in the electroplating bath via a gantry crane. During the electroplating process, the crane also lifts and lowers the housing back and forth within the bath, ensuring a more uniform deposition of metal ions onto the housing. The electroplating line requires numerous devices to be controlled, requiring frequent maintenance and specialized technicians, resulting in high overall costs. Summary of the Invention

Detailed implementation mode

[0036] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as a limitation of the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0037] The coating equipment based on the surface treatment of the housing provided by the embodiments of the present application can be applied to the surface coating of the housing, replacing the gantry crane in the original electroplating workshop. It requires fewer control devices, has a simple operation structure, is convenient for maintenance, and effectively reduces costs.

[0038] As Figure 1-8 shown, the coating equipment based on the surface treatment of the housing provided by the embodiments of the present application includes a support frame 10, an electroplating bath 20, a drive assembly 30, a conductive component 40, a dipping plating assembly 50, a conveying assembly 60 and a hanging material assembly 70.

[0039] Among them, the support frame 10 is arranged on the electroplating bath 20, the driving component 30 is arranged on the electroplating bath 20, the driving component 30 is used for stirring the electroplating solution in the electroplating bath 20, and the conductive component 40 is arranged on the electroplating bath 20.

[0040] It should be noted that the conductive component 40 is a conductive plate made of titanium plate. The conductive component 40 is inserted into the electroplating bath 20, and the external power supply is electrically connected to the conductive component 40. The solution in the electroplating bath 20 is conducted through the conductive component 40. At this time, the metal medium in the solution serves as the anode, and the housing serves as the cathode, so that the solution in the electroplating bath 20 is electroplated and attached to the surface of the housing.

[0041] The dip coating assembly 50 is movably arranged on the electroplating bath 20. The dip coating assembly 50 includes a first driving component 501, a fixing frame 502, a fastening connecting piece 503, a telescopic adjusting mechanism 504, and a connecting piece 505.

[0042] Among them, the first driving component 501 is arranged on the electroplating bath 20. There are two groups of fixing frames 502, and the two groups of fixing frames 502 are respectively movably arranged in the electroplating bath 20. The fastening connecting piece 503 is arranged on the two groups of fixing frames 502, and the fastening connecting piece 503 is connected to the output end of the first driving component 501. There are two groups of telescopic adjusting mechanisms 504, and the two groups of telescopic adjusting mechanisms 504 are respectively arranged on the corresponding fixing frames 502. The connecting piece 505 is arranged at the movable end of the telescopic adjusting mechanism 504, and the connecting piece 505 is in contact connection with the driving component 30.

[0043] It should be noted that in this embodiment, the first driving component 501 is a hydraulic cylinder. The first driving component 501 is controlled by a control switch and connected to a power supply to drive the fixing frame 502 to move up and down, adjust the height of the connecting piece 505, and make the connecting piece 505 cooperate with the hanging component 70 conveyed on the guide rail 601, so as to bring the housing on the hanging component 70 into the electroplating bath 20 to complete the coating.

[0044] The conveying component 60 is arranged on the support frame 10. The hanging component 70 is detachably arranged on the conveying component 60, and the hanging component 70 is connected to the connecting piece 505.

[0045] The hanging component 70 includes a connecting shaft rod 701, a limiting piece 702, and a clamping piece 703.

[0046] Among them, there are multiple groups of limiting pieces 702, and the multiple groups of limiting pieces 702 are linearly arranged in an array on the connecting shaft rod 701. The clamping piece 703 is arranged on the connecting shaft rod 701, and the clamping piece 703 is detachably arranged on the conveying component 60. The connecting shaft rod 701 is connected to the connecting piece 505.

[0047] It should be noted that the multiple sets of limit members 702 are designed according to the internally placed housings. One or more housings can be placed in the limit members 702 and designed according to the actual situation. The clamping member 703 is provided with a limit through groove, which is limit-hung on the hanging member 6033, and the clamping member 703 is in contact connection with the lifting transmission member 6032 of the lifting.

[0048] Specifically: The steps for electroplating and coating the housing are as follows: Place the housing to be coated on the hanging component 70. The hanging component 70 moves and conveys on the conveying component 60 and stops conveying when it reaches directly above the electroplating bath 20. Operate the first driving component 501 to drive the fixed frame 502 to move up and down. During the upward movement of the fixed frame 502, it drives the connecting member 505 to be connected to the connecting shaft rod 701, and drives the clamping member 703 to disengage from the conveying component 60. Then operate the first driving component 501 again to drive the limit member 702 to sink into the electroplating bath 20. Energize the conductive component 40 in the electroplating bath 20. At this time, the conductive component 40 conducts electricity to the solution in the electroplating bath 20. The solution is the anode and the housing is the cathode. The metal medium in the solution of the electroplating bath 20 adheres to the surface of the housing to form a film, thus completing the coating process. After completing the coating process, operate the first driving component 501 again to drive the connecting shaft rod 701 to rise. At this time, the clamping member 703 cooperates with the conveying component 60 and is clamped on the conveying component 60, facilitating the movement to the next working station.

[0049] In an embodiment of the present application, as Figure 3 shown, the conveying component 60 includes a guide rail 601, a conveying chain 602, and a hanging connection mechanism 603.

[0050] Among them, the guide rail 601 is arranged on the support frame 10, the conveying chain 602 is movably arranged on the guide rail 601, the hanging connection mechanism 603 is detachably arranged on the conveying chain 602, and the hanging connection mechanism 603 is clamped with the clamping member 703.

[0051] It should be noted that in this embodiment, the described guide rail 601 is installed on the support frame 10, and the height of the guide rail 601 is designed according to the actual situation. The conveying chain 602 passes through the guide rail 601 during the conveying process and is limited by the guide rail 601. The length and shape of the guide rail 601 are designed according to the moving path required by the housing in the coating process. The conveying chain 602 is driven by a sprocket and a motor for conveying. The sprocket and the motor are prior arts, so no specific description is made here.

[0052] Further, in order to conveniently and precisely control the conveying chain 602 to drive the hanging material connection mechanism 603 to move to the position where it cooperates with the dip plating assembly 50 and stop, the operation of the conveying chain 602 is controlled by a sensor or a PLC control system. For example, an optoelectronic sensor is used to emit infrared rays and receive reflected signals to determine whether an item reaches a specified position. The sensor or the PLC control system is a prior art, so no specific description is given here.

[0053] The hanging material connection mechanism 603 includes a fastening and adjusting member 6031, a lifting transmission member 6032, and a hanging member 6033.

[0054] Among them, the fastening and adjusting member 6031 is detachably arranged on the conveying chain 602, the lifting transmission member 6032 is arranged on the fastening and adjusting member 6031 in a lifting manner, and the hanging member 6033 is arranged on the fastening and adjusting member 6031 in a rotatable manner.

[0055] It should be noted that a screw rod is provided at the top of the fastening and adjusting member 6031, and a threaded hole is provided on the conveying chain 602. The screw rod is threadedly connected in the threaded hole, which is convenient for disassembling, installing, and replacing the hanging material connection mechanism 603 at different positions on the conveying chain 602 according to the installation position of the housing.

[0056] Further, the hanging member 6033 includes a shaft installed on the fastening and adjusting member 6031. A hook-shaped hanging plate is connected to the shaft through a scroll spring. When the clamping member 703 is disengaged from the hanging member 6033, the scroll spring drives the hanging plate to rebound. At this time, when driving the limiting member 702 to move downward, it will not contact the hanging plate and directly fall into the electroplating bath 20.

[0057] In an embodiment of the present application, as Figure 4 shown, the fastening and adjusting member 6031 includes a housing 60311, an inner movable plate 60312, a lower clamping plate 60313, an upper clamping plate 60314, a through hole 60315, a blind groove 60316, and a through groove 60317.

[0058] Among them, the housing 60311 is detachably arranged on the conveying chain 602, the inner movable plate 60312 is rotatably arranged inside the housing 60311, and the lower clamping plates 60313 are arranged in an annular array on the bottom wall of the inner movable plate 60312. The upper clamping plates 60314 are arranged in an annular array on the top wall of the inner movable plate 60312. The lower clamping plate 60313 and the upper clamping plate 60314 are respectively in contact connection with the lifting transmission member 6032. The through hole 60315 is opened on the inner movable plate 60312. The blind groove 60316 is opened between two adjacent groups of upper clamping plates 60314, and the through groove 60317 is opened outside two adjacent groups of upper clamping plates 60314.

[0059] It should be noted that in this embodiment, the inner movable plate 60312 is rotatably arranged in the outer housing 60311 through bearings. The lower clamping plate 60313 and the upper clamping plate 60314 are respectively provided with inclined end faces. The number of the lower clamping plates 60313 is the same as that of the upper clamping plates 60314, and the lower clamping plates 60313 and the upper clamping plates 60314 are annularly arranged on the inner movable plate 60312 and are distributed in a ring with their heads and tails connected.

[0060] In an embodiment of the present application, as Figure 4 and Figure 5 shown, the lifting transmission member 6032 includes a movable base 60321, a fixed shaft rod 60322, a lower top plate 60323, a first pressing rod 60324, a second pressing rod 60325, a reset member 60326 and an upper pressing plate 60327.

[0061] Among them, the movable base 60321 is movably arranged in the outer housing 60311. One end of the fixed shaft rod 60322 is arranged on the movable base 60321. The lower top plate 60323 is arranged on the movable base 60321, and the lower top plate 60323 is in contact connection with the lower clamping plate 60313. The first pressing rod 60324 is arranged on the bottom wall of the movable base 60321, the second pressing rod 60325 is arranged on the movable base 60321, and the two ends of the reset member 60326 are respectively connected to the top wall of the fixed shaft rod 60322 and the top wall of the inner cavity of the outer housing 60311. The upper pressing plate 60327 is arranged on the top wall of the fixed shaft rod 60322, and the upper pressing plate 60327 is in contact connection with the upper clamping plate 60314.

[0062] It should be noted that an opening groove for the lifting movement of the first pressing rod 60324 and the second pressing rod 60325 is provided on the outer housing 60311. The movable base 60321 moves up and down in the outer housing 60311 and is reset by the reset member 60326. The reset member 60326 is a reset spring. Inclined end faces are respectively provided on the lower top plate 60323 and the upper pressing plate 60327. When the movable base 60321 moves upward, the lower top plate 60323 abuts against the lower clamping plate 60313, and the inner movable plate 60312 is pushed to rotate by the mutual fitting of the inclined end faces. And the rotation angle is such that when the upper pressing plate 60327 falls, it cooperates with the upper clamping plate 60314. When the movable base 60321 moves downward, the upper pressing plate 60327 cooperates with the inclined end face of the upper clamping plate 60314, so as to push the inner movable plate 60312 to rotate again, and the rotation direction and the rotation angle are the same.

[0063] Furthermore, when the hook 5052 rises and pushes the connecting member 703 and the hanging member 6033 to separate, the upper pressure plate 60327 is inserted into the blind groove 60316. At this time, the first pressure rod 60324 no longer interferes with the hanging member 6033. The hanging member 6033 is reset by the scroll spring and no longer connected to the connecting member 703 when it falls. When the coating is completed, the hook 5052 drives the connecting member 703 to move upward again, pushing the inner movable plate 60312 to rotate. At this time, the upper pressure plate 60327 is inserted into the through groove 60317. At this time, the first pressure rod 60324 moves downward to interfere with the hanging member 6033. During the downward movement of the connecting member 703, it is again engaged with the hanging member 6033. The second pressure rod 60325 is pressed against the top wall of the connecting member 703, ensuring stability during transportation.

[0064] In one embodiment of the present application, Figure 6 As shown, the fastening connector 503 includes an outer collar 5031 , a fixing rod 5032 and a fixing collar 5033 .

[0065] There are two groups of outer rings 5031 , which are arranged on corresponding fixing frames 502 , fixing rods 5032 are arranged in the two groups of outer rings 5031 , fixing rings 5033 are arranged on the fixing rods 5032 , and fixing rings 5033 are arranged at the output end of the first driving component 501 .

[0066] It should be noted that the outer collar 5031 is welded to the fixing frame 502, and the fixing rod 5032 is inserted into the two sets of outer collars 5031 and a fixing collar 5033 is sleeved on the fixing rod 5032. The fixing collar 5033 is connected to the first driving component 501. When the first driving component 501 is operated, the fixing frame 502 is driven to move up and down to adjust the height.

[0067] In one embodiment of the present application, Figure 7 As shown, the telescopic adjustment mechanism 504 includes a hollow shell 5041 , a movable plate 5042 , a buffer component 5043 and a push rod 5044 .

[0069] It should be noted that a limiting sliding groove is provided in the hollow housing 5041, and a slider that is limited and slides in the limiting sliding groove is provided on the movable plate 5042, so that the movable plate 5042 is limited and slides in the limiting sliding groove. The buffer member 5043 is a buffer spring. When the driving assembly 30 operates, when the connecting member 505 is pushed up and down by the driving assembly 30, it is reset by the buffer member 5043.

[0070] In an embodiment of the present application, as Figure 6 shown, the connecting member 505 includes a fastening plate 5051 and a hook 5052.

[0071] Among them, the fastening plate 5051 is arranged on the ejector rod 5044, and there are multiple groups of hooks 5052. The multiple groups of hooks 5052 are linearly arranged on the fastening plate 5051.

[0072] It should be noted that a convex block is provided at the bottom of the fastening plate 5051. The position of the convex block corresponds to the position of the driven rod holder 30232, and the convex block is arranged between the hooks 5052.

[0073] In an embodiment of the present application, as Figure 8 shown, the driving assembly 30 includes a stirring mechanism 301, a feeding mechanism 302, and a conveyor belt 303.

[0074] Among them, the stirring mechanism 301 is arranged on the electroplating bath 20. The stirring mechanism 301 is used to stir the electroplating solution in the electroplating bath 20. The feeding mechanism 302 is rotatably arranged in the electroplating bath 20, and the feeding mechanism 302 is in contact connection with the fastening plate 5051. The conveyor belt 303 is sleeved on the stirring mechanism 301 and the feeding mechanism 302.

[0075] It should be noted that the stirring mechanism 301 drives the feeding mechanism 302 to rotate synchronously through the conveyor belt 303. During the process of stirring the solution in the electroplating bath 20, the feeding mechanism 302 and the fastening plate 5051 are synchronously driven to be in contact, and the fastening plate 5051 is pushed to move up and down, so that the adhesion of the solution in the electroplating bath 20 is higher and the coating is more uniform during the electroplating process.

[0076] In an embodiment of the present application, as Figure 8 shown, the stirring mechanism 301 includes a second driving member 3011, a rotating shaft 3012, and a stirring rod 3013.

[0077] Among them, the second driving member 3011 is arranged on the electroplating bath 20. The rotating shaft 3012 is rotatably arranged in the electroplating bath 20, and the rotating shaft 3012 is arranged at the output end of the second driving member 3011. There are multiple groups of stirring rods 3013. The multiple groups of stirring rods 3013 are linearly arranged on the rotating shaft 3012.

[0078] It should be noted that the second driving component 3011 is a stepping motor, and the output end of the stepping motor is connected to the rotating shaft 3012 through a speed reducer. By controlling the switch to connect to the power supply to operate the second driving component 3011, the rotating shaft 3012 is driven to rotate, and then the stirring rod 3013 is driven to rotate. When the stirring rod 3013 rotates, it will not contact the conductive component 40. Thereby, the electroplating solution in the electroplating tank 20 is stirred to prevent precipitation.

[0079] In an embodiment of the present application, as Figure 8 shown, the blanking mechanism 302 includes a rotating shaft rod 3021, a blanking component 3022, and a follower 3023.

[0080] Among them, the rotating shaft rod 3021 is rotatably arranged in the electroplating tank 20, the blanking component 3022 is arranged on the rotating shaft rod 3021, the follower 3023 is arranged in the electroplating tank 20, and the blanking component 3022 and the follower 3023 are in contact connection.

[0081] It should be noted that rubber wheels cooperating with the conveyor belt 303 are respectively provided on the rotating shaft rod 3021 and the rotating shaft 3012. The surface of the rubber wheel is provided with anti-slip lines, and the conveying transmission is stable and the phenomenon of idling is prevented. The top of the blanking component 3022 is provided with a rounded corner, and the blanking component 3022 and the follower 3023 are in tangential cooperation.

[0082] The follower 3023 includes a limit frame 30231, a follower rod frame 30232, a limit baffle 30233, an elastic component 30234, and a connection bracket 30235.

[0083] Among them, the limit frame 30231 is arranged in the electroplating tank 20, the follower rod frame 30232 is movably arranged in the limit frame 30231, and the follower rod frame 30232 and the blanking component 3022 are in contact connection. The limit baffle 30233 is arranged in the electroplating tank 20, the connection bracket 30235 is arranged on the follower rod frame 30232, and the two ends of the elastic component 30234 are respectively connected to the limit baffle 30233 and the connection bracket 30235.

[0084] It should be noted that the elastic component 30234 is a spring. The connection bracket 30235 connects two groups of follower rod frames 30232 together for synchronous lifting and lowering movement. And the heights of the two groups of follower rod frames 30232 are limited to be the same by the limit frame 30231. A rounded corner is provided at the bottom of the follower rod frame 30232, and when the blanking component 3022 rotates, it is tangent to the follower rod frame 30232 and is pushed upward. The convex block on the fastening plate 5051 abuts against the top of the follower rod frame 30232, so as to drive the shell to lift and lower in the electroplating solution synchronously, thereby generating an electroplating film on the surface of the shell.

[0085] It should be noted that during the electroplating process of the housing, pretreatment and post-treatment processing techniques are respectively adopted. The pretreatment process includes: hanging, installing the housing on the hanging component 70, then placing it on the conveying component 60 for conveying, conveying it above the chemical polishing tank, and immersing the hanging component 70 into the chemical polishing tank. After chemical polishing, the hanging component 70 is taken out and conveyed to the municipal water washing tank for washing. After washing, the hanging component 70 is conveyed to the neutralization tank, and finally moved to the municipal water washing tank again to complete the pretreatment.

[0086] The post-treatment process includes: driving the hanging component 70 by the conveying component 60 to move the housing that has completed the pretreatment process, and successively passing through the oxidation tank, multiple pure water washing tanks, dyeing tank, pure water washing tank, sealing hole tank, pure water washing tank, ash removal tank, pure water washing tank, hot water washing tank, drying, and unloading to complete electroplating. Finally, after inspection and packaging, it can be stored in the warehouse (the above steps are the prior art of housing electroplating). When passing through each treatment tank, through the cooperation of the immersion plating component 50 and the conveying component 60, the immersion plating component 50 drives the hanging component 70 to disassemble and assemble on the conveying component 60 and complete the processing.

[0087] The coating steps of the coating equipment based on the surface treatment of the housing in the embodiment of the present application are as follows:

[0088] The steps of conveying the housing in place and feeding it into the electroplating tank 20 are: placing the housing to be coated on the hanging component 70, and the hanging component 70 moves and conveys on the conveying component 60. When it is conveyed directly above the electroplating tank 20 at the electroplating station to be processed, the conveying stops. The first driving component 501 is operated to drive the fixed frame 502 to move up and down. During the rising process of the fixed frame 502, the hook 5052 is driven to be connected with the connecting shaft rod 701, and the clamping part 703 is driven to disengage from the conveying component 60.

[0089] When disengaging, the clamping part 703 is connected with the first pressure rod 60324 to push the movable base 60321 to move up synchronously. The lower top plate 60323 abuts against the lower clamping plate 60313, and the inner movable plate 60312 is pushed to rotate by the mutual fitting of the inclined end faces. And the rotation angle is such that when the upper pressure plate 60327 falls, it cooperates with the upper clamping plate 60314. At this time, the upper pressure plate 60327 is inserted into the blind groove 60316, and the first pressure rod 60324 does not abut against the hanging part 60,33. The hanging part 6033 is reset by the volute spring and is not connected with the falling clamping part 703. The first driving component 501 is operated again to drive the limiting part 702 to sink into the electroplating tank 20.

[0090] The steps to keep the electroplating solution in the electroplating bath 20 uniform and the coating on the surface of the housing uniform during the electroplating process are as follows: Operate the second driving component 3011 to drive the rotating shaft 3012 to rotate, and then drive the stirring rod 3013 to rotate, thereby stirring the electroplating solution in the electroplating bath 20 to prevent precipitation. During the process of the stirring mechanism 301 stirring the solution in the electroplating bath 20, it synchronously drives the ejecting mechanism 302 to contact the fastening plate 5051, and pushes the fastening plate 5051 to move up and down, so that the adhesion of the solution in the electroplating bath 20 is higher during the electroplating process. When the ejecting component 3022 rotates, it is tangent to the driven rod frame 30232 and pushes upward. The bump on the fastening plate 5051 abuts against the top of the driven rod frame 30232, thereby synchronously lifting and driving the fastening plate 5051. The housing on the hook 5052 rises and falls in the electroplating solution, so that an electroplating film is formed on the surface of the housing.

[0091] The steps for the housing after electroplating to be hung on the conveying component 60 again are as follows: After electroplating is completed, operate the first driving component 501 again to drive the fixed frame 502 to rise, and drive the clamping part 703 to be connected to the first pressing rod 60324 again. Then push the movable base 60321 to move upward. Similarly, the lower top plate 60323 abuts against the lower clamping plate 60313 again, driving the inner movable plate 60312 to rotate. When it falls, the upper pressing plate 60327 is inserted into the through groove 60317. The first pressing rod 60324 moves downward and abuts against the hanging part 6033, thereby driving the hanging part 6033 to rotate. When the clamping part 703 moves downward, it is clamped on the hanging part 6033. Thus, when the first driving component 501 drives the fixed frame 502 to descend, the hanging component 70 after electroplating is left on the conveying component 60 and conveyed to the next working station through the conveying component 60.

[0092] In summary, the coating equipment based on the housing surface treatment in the embodiment of the present application replaces the gantry crane in the original electroplating workshop, requires fewer control devices, has a simple operation structure, is convenient for maintenance, and effectively reduces costs.

Those of ordinary skill in the art can make changes, modifications, substitutions, and deformations to the above embodiments within the scope of the present application.
