Description

Technical Field

[0001] The invention relates to the technical field of jewelry processing equipment, in particular to jewelry surface treatment equipment. Background Art

[0002] Jewelry surface treatment technology is mainly divided into two categories: mechanical treatment and electrochemical treatment. Mechanical treatment mainly uses related mechanical tools to grind, polish, sandblast, etc. on jewelry in order to achieve the required process requirements and effects.

This method is particularly suitable for complex jewelry designs and hard-to-reach areas.

During processing, it is necessary to polish on the polishing machine first, and then manually transfer to the electroplating machine for electroplating.

DETAILED DESCRIPTION

[0009] The jewelry surface treatment device 100 of the present invention is as follows: Figure 1-3 As shown, it includes a frame 1, which serves as the structural basis of the entire equipment. A horizontally arranged platform plate 2 is provided on the frame 1, and the platform plate 2 serves as the installation basis of various mechanisms. A plating container station 60 is installed on the front side of the platform plate 2.

[0010] The electroplating container station 60 includes a preliminary cleaning liquid container 3, an electrolyte container 4, an activation liquid container 5 and a plurality of electroplating liquid containers 6. The preliminary cleaning liquid container 3 contains cleaning liquid, which plays a role in preliminary cleaning of the jewelry before processing. The electrolyte container 4 contains electrolyte, which can electrolytically process the jewelry to remove impurities such as oil stains on the surface. The activation liquid container 5 contains activator, which can activate the surface of the jewelry to improve the subsequent electroplating treatment effect. A plurality of electroplating liquid containers 6 are provided, and corresponding electroplating liquids can be placed according to different electroplating requirements to achieve electroplating treatment of the jewelry.

[0011] Carbon brushes 7 are also installed on the platform plate 2 to correspond to the electrolyte container 4, the activation liquid container 5 and each plating liquid container 6. The carbon brushes 7 play a vital role in the electroplating process. The carbon brushes 7 are arranged on the mounting plate 36 of the platform plate 2 and can be used to control the distance between the carbon brushes 7 and the jewelry or the clamping mechanism 63. The carbon brushes 7 can form an electric circuit when the jewelry is processed to ensure normal surface treatment operations such as electroplating.

[0012] On the rear side of the carbon brush 7, the platform plate 2 is equipped with a flushing container station 66, a drying nozzle 8, a polishing station 61 and an ultrasonic cleaning machine 9, wherein the flushing container station 66 includes a plurality of cleaning liquid containers 10, each of which is arranged in the order of increasing impurity concentration contained in the cleaning liquid, such as pure water, mineral water, and tap water, to meet different cleaning requirements, realize layer-by-layer cleaning of the jewelry, and ensure that no other impurities remain on the surface of the jewelry. The polishing station 61 includes a polishing rotary motor 11, and a polishing drum 12 is installed on the output shaft of the polishing rotary motor 11. The polishing drum 12 contains polishing media, and the jewelry can be put into the polishing drum 12 to achieve the corresponding polishing operation.

[0013] like Figure 4 and Figure 7 As shown, in order to realize the hanging and grabbing of jewelry and the transfer between various stations, a moving mechanism 62 is also installed on the platform plate 2, and a clamping mechanism 63 capable of hanging jewelry is installed on the moving mechanism 62. Fig.11 , 13 , 14, 15. The moving mechanism 62 can be an existing gear rack moving mechanism, a screw nut moving mechanism, a telescopic rod moving mechanism or an XYZ high-precision moving platform, which can realize the movement in three axes and the transfer between various mechanisms and workstations.

[0014] The clamping mechanism 63 can be an existing clamping claw, caliper or manipulator that can be used to hang jewelry, so that the clamping mechanism 63 can grab the jewelry to be processed and transfer it under the drive of the moving mechanism 62. The clamping mechanism 63 can rotate relative to the moving mechanism 62, so that the jewelry can rotate itself during cleaning, polishing or electroplating operations, so that the surface of the jewelry can be more fully in contact with the processing medium, so that the surface treatment effect is better.

[0015] When the clamping mechanism 63 drives the jewelry into the electroplating liquid container 6, the carbon brush 7 moves close to the clamping mechanism 63 and contacts with it, so that an electric circuit can be formed between the jewelry and the electroplating liquid, thereby realizing the corresponding electroplating operation. A control panel 13 is installed at the front end of the frame 1. The control panel 13 is connected to the control system 64 and each station component through a control line. By inputting different jewelry surface treatment parameters in the control panel 13, the jewelry can be driven by the clamping mechanism 63 and the moving mechanism 62 to go back and forth between the preliminary cleaning liquid container 3, the electrolyte container 4, the activation liquid container 5, the electroplating liquid container 6, the rinsing container station 66, the drying nozzle 8, the polishing station 61 and the ultrasonic cleaning machine 9 to realize the cleaning, polishing and electroplating of the jewelry.

[0016] The device also includes a detection mechanism 65, which requires at least four photoelectric switches installed on the guide rail to determine the starting position of the moving mechanism 62. If an error occurs, the controller will operate the moving mechanism 62 to return it to the machine starting position specified in the step. In addition, the device is also equipped with a power supply to provide power to each component. Other detection mechanisms that can identify the moving parts, as well as power supplies and other necessary components for providing power to each component can also be installed inside the above-mentioned device.

[0017] Furthermore, in order to realize the lateral, longitudinal and vertical movement of jewelry between different processing stations, such as Figure 3 , Figure 4 and Figure 5 As shown, the moving mechanism 62 includes an X-axis motor 14, a Y-axis motor 15, and a Z-axis motor 16. Screw rods 17 and transverse guide rails 18 are provided on both sides of the platform plate 2. A transverse seat 19 is installed on the transverse guide rail 18. A nut 20 that cooperates with the screw rod 17 is provided in the transverse seat 19. The output shaft of the X-axis motor 14 is connected to one of the screw rods 17. When the X-axis motor 14 is started, it can drive the transverse seat 19 to move laterally on the transverse guide rail 18.

[0018] In order to achieve synchronous movement of the transverse seats 19 on both sides, pulleys 21 are provided at the ends of the two screw rods 17, and a synchronous belt 22 is installed between the two pulleys 21. When the X-axis motor 14 is started, it can drive the transverse seats 19 on both sides to move synchronously.

[0019] A cross slide 23 is mounted on the two transverse seats 19, and the Y-axis motor 15 and the Z-axis motor 16 provide power for the longitudinal and vertical movement of the cross slide 23, respectively. A jewelry fixture rotating motor 24 is mounted on the slide of the cross slide 23, and a clamping mechanism 63 is mounted on the output shaft of the jewelry fixture rotating motor 24. The setting of the jewelry fixture rotating motor 24 allows the jewelry to rotate relative to the moving mechanism 62, so as to achieve better cleaning, polishing and electroplating operations.

[0020] In order to achieve the snap-fitting of the container mouths of the preliminary cleaning liquid container 3, the electrolyte container 4, the activation liquid container 5 and the several plating liquid containers 6 and avoid the volatilization of the solutions in the containers when not in operation, the preliminary cleaning liquid container 3, the electrolyte container 4, the activation liquid container 5 and the several plating liquid containers 6 are arranged side by side.

[0021] like Figure 6 As shown, a horizontally arranged flip rod 25 is installed at the front end of the frame 1, and a flip plate 26 is provided on the flip rod 25. A buckle cover 27 corresponding to the stage cleaning liquid cup 3, the electrolyte container 4, the activation liquid container 5, and the plating liquid container 6 is provided on the inner side of the flip plate 26.

[0022] Push plates 29 are also provided on both sides of the flip rod 25, and a first tension spring 28 is installed between the push plate 29 and the frame 1. The first tension spring 28 always has a tendency to pull the buckle cover 27 to rotate away from the container mouth. A push rod 30 is installed on the transverse displacement seat 19, and a rolling bearing 31 is installed at the end of the push rod 30. The rolling bearing 31 is arranged corresponding to the push plate 29. When the transverse displacement seat 19 moves close to the flip rod 25, the push rod 30 can contact the push plate 29 and drive the buckle cover 27 to rotate until it is buckled with the container mouth.

[0023] When the device is not in use, the lateral displacement seat 19 is located near the flip rod 25, and the push rod 30 pushes the push plate 29, so that the buckle cover 27 on the flip plate 26 can rotate and buckle with the container mouth to prevent the internal solution from volatilizing. When the device needs to be used, after the jewelry is hung on the clamping mechanism 63, the specified parameters are input into the control panel 13, and the lateral displacement seat 19 will first move away from the flip rod 25. Under the tension of the first tension spring 28, the buckle cover 27 is flipped open and maintained in the open state to facilitate subsequent surface processing. The rolling bearing 31 is arranged at the front end of the push rod 30, which can convert the sliding friction between the push rod 30 and the push plate 29 into rolling friction, which can effectively reduce the friction during the contact process and extend the service life of each component.

[0024] Furthermore, if Figure 4 , 6 As shown in FIG. 7 , in order to facilitate the assembly and disassembly of the push rod 30 on the traverse seat 19, a rolling bearing 31 is installed at one end of the push rod 30, a stud is provided at the other end of the push rod 30, and a screw hole matching the stud is provided on the traverse seat 19. By rotating the stud, the initial length of the push rod 30 extending out of the traverse seat 19 can be adjusted to change the distance between the traverse seat 19 and the push plate 29 when the traverse seat 19 is not in use, that is, the initial reset position of the traverse seat 19 when it is not in use.

[0025] Furthermore, in order to realize the installation of the preliminary cleaning liquid container 3, the electrolyte container 4, the activation liquid container 5 and each plating liquid container 6 on the platform plate 2, as shown in FIG. Figure 8As shown, a vertically lifting tray 32 is installed on the front side of the platform plate 2, wherein the vertical lifting of the tray 32 can be realized by an electric push rod or a telescopic cylinder. A heating plate 33 is installed on the upper side of the tray 32, and a container fixing ring 34 is provided on the upper side of the heating plate 33 to match the preliminary cleaning liquid container 3, the electrolyte container 4, the activation liquid container 5 and each plating liquid container 6. The container fixing ring 34 can provide positioning for the installation of each container. In order to realize the fixed installation of the container fixing ring 34 on the tray 32, a plurality of clamps 35 are installed between the container fixing ring 34, the heating plate 33 and the tray 32, and the clamps 35 are located between adjacent containers.

[0026] Furthermore, in order to realize the action drive of the carbon brush 7 moving close to and contacting the clamping mechanism 63 to form an energized circuit, as shown in FIG. Fig. 9 and Fig.10 As shown, the carbon brush 7 is arranged on the mounting plate 36, a slide rail seat 37 is provided at the lower side of the mounting plate 36, a slider 38 matching with the slide rail seat 37 is provided at the bottom of the mounting plate 36, and the mounting plate 36 and the carbon brush 7 thereon can move along the slide rail seat 37.

[0027] An electromagnet 39 is also installed at the bottom of the mounting plate 36, and a vertical plate 40 is provided at the front end of the mounting plate 36. An iron block 41 corresponding to the electromagnet 39 is provided on the vertical plate 40, wherein a second tension spring 42 is also installed between the mounting plate 36 and the slide rail seat 37. The second tension spring 42 always has a tendency to keep the carbon brush 7 on the mounting plate 36 away from the electroplating liquid container 6. When the clamping mechanism 63 drives the jewelry into the electroplating liquid container 6, the electromagnet 39 is energized and attracted to the iron block 41 to overcome the tension of the second tension spring 42, so that the carbon brush 7 contacts the clamping mechanism 63 and forms an energized circuit.

[0028] Furthermore, in order to adjust the vertical height of the mounting plate 36 so as to adapt to different types of clamping mechanisms 63 and form a contact power circuit, a height adjustment screw 43 is installed at the bottom of the slide rail seat 37, and a through hole matching the height adjustment screw 43 is provided on the platform plate 2. A first nut 44 and a second nut 45 are mounted on the height adjustment screw 43, and the first nut 44 and the second nut 45 are respectively located on the upper and lower sides of the platform plate 2, and the height adjustment screw 43 is installed at a fixed height on the platform plate 2 by clamping the two nuts.

[0029] After rotating the first nut 44 and the second nut 45 away from the platform plate 2, the height adjustment screw 43 can be vertically raised and lowered relative to the platform plate 2. After the adjustment is completed, the two nuts are rotated to the upper and lower sides of the platform plate 2 again for clamping and positioning. By rotating the first nut 44 and the second nut 45, the height distance between the slide rail seat 37 and the platform plate 2, that is, the height distance position of the mounting plate 36 and the carbon brush 7 thereon relative to the platform plate 2, can be adjusted.

[0030] Further, in order to achieve the hanging of the jewelry on the clamping mechanism 63 and drive the jewelry to rotate relative to the moving mechanism 62 to improve the treatment effects of cleaning, polishing, and electroplating of the jewelry itself, as Fig.11 shown, the clamping mechanism 63 includes a first conductive column 46 provided on the output shaft of the jewelry fixture rotation motor 24. A circular conductive plate 47 is provided at the bottom of the first conductive column 46. The carbon brush 7 can contact the circular conductive plate 47 to form an energized circuit. The outer circumference of the circular conductive plate 47 is circular, and while forming an energized circuit in contact with the carbon brush 7, it does not affect the rotation of the clamping mechanism 63 itself.

[0031] The bottom of the circular conductive plate 47 is installed with a second conductive column 49 through a universal joint 48. The outer circumference of the universal joint 48 is sleeved with insulating grease 50. Through the connection of the universal joint 48, when the circular conductive plate 47 rotates, it can drive the second conductive column 49 to swing unrestrictedly within the circumferential range. Due to the wrapping restriction of the insulating grease 50, the second conductive column 49 can swing within a small range relative to the first conductive column 46. The setting of the above structure can drive the jewelry to swing within a small range to improve the surface treatment effects of cleaning, polishing, and electroplating, and at the same time can limit the swinging range of the jewelry to avoid the jewelry colliding with or interfering with each component during the processing, thus playing a role in protecting the jewelry.

[0032] To achieve the hanging of the jewelry, a hook 51 and a stop lever 52 are installed at the bottom of the second conductive column 49. A torsion spring 53 is installed on the rotating shaft of the stop lever 52. The torsion spring 53 always has a tendency to rotate the stop lever 52 to close the opening of the hook 51. When installing the jewelry, only need to overcome the elastic force of the torsion spring 53 to push the stop lever 52 to rotate, expose the opening of the hook 51, and then hang the jewelry on the hook 51. After releasing the stop lever 52, the stable hanging of the jewelry on the clamping mechanism 63 can be achieved. The hook 51, the second conductive column 49, the universal joint 48, and the circular conductive plate 47 in the above clamping mechanism 63 are all made of conductive materials to ensure the formation of a contacting energized circuit.

[0033] Further, another structural form of the clamping mechanism 63 is as Fig.13 shown, including a first conductive column 46 provided on the output shaft of the jewelry fixture rotation motor 24. A circular conductive plate 47 is provided at the bottom of the first conductive column 46. The carbon brush 7 can contact the circular conductive plate 47 to form an energized circuit. The bottom of the circular conductive plate 47 is connected with a non-conductive material fixture 57 through a conductive shaft. A card slot 58 is provided on the outer circumference of the non-conductive material fixture 57. A limit energized hook 59 is also installed on the non-conductive material fixture 57. The limit energized hook 59 is connected to the circular conductive plate 47 through a wire.

[0034] As Fig.14 and Fig.15As shown, the position-limiting power-on hook 59 can be directly hung with small-volume rings and other jewelry, and can rotate with the jewelry fixture rotating motor 24 while being powered on. Multiple position-limiting power-on hooks 59 can also be installed in the clamping mechanism 63 to improve production efficiency. When it is necessary to hang larger jewelry such as bracelets, the bracelets can be positioned and hung in the slots 58 of the non-conductive material fixture 57. Since the non-conductive material fixture 57 itself cannot be powered on, the position-limiting power-on hook 59 needs to be hung on the bracelet to achieve the power-on requirement of the jewelry to be electroplated.

[0035] Fig.14 It is a schematic diagram of a state where a small-volume jewellery such as a ring is hung on the clamping mechanism 63.

[0036] Fig.15 It is a schematic diagram of the state where a relatively large piece of jewelry, such as a bracelet, is hung on the clamping mechanism 63.

[0037] Furthermore, in order to realize the contacting energizing circuit during the electrolysis, activation, electroplating and other operations, as Fig.12 As shown, the electrolyte container 4, the activation liquid container 5 and the plating liquid container 6 are all equipped with a conductive mesh 54, which is connected to the electroplating power supply together with the carbon brush 7 through a wire, and the carbon brush 7 is in contact with the clamping mechanism 63. When the jewelry enters the electrolyte container 4, an electrical circuit is formed among the jewelry, the electrolyte, the conductive mesh 54, the clamping mechanism 63 and the carbon brush 7.

[0038] Furthermore, in order to blow away residual impurities on the surface of the jewelry during the processing, an air pump 55 is installed on the platform plate 2, and a blow pipe 56 is installed on the clamping mechanism 63. The blow pipe 56 is connected to the air pump 55 through an air path. The blow pipe 56 can blow high-pressure gas toward the position where the jewelry is hung, and can blow away and clean impurities attached to or remaining on the surface of the jewelry without damaging the jewelry.

[0039] Although the above has described in detail the mechanized structure of each part of the jewelry surface treatment equipment, Fig.16 An overall system schematic diagram is shown to describe the working principle of the present invention, as shown below: The frame 1 and the platform plate 2 are mechanically connected together. The control panel 13 and the control system 64 are mounted on the frame 1, and the control panel 13 and the control system 64 maintain electrical communication. The control system 64 also communicates electrically with motors such as the X-axis motor 14, the Y-axis motor 15, the Z-axis motor 16, the polishing rotation motor 11, and the jewelry fixture rotation motor 24. The control system 64 also communicates electrically with the rinse container station 66, the polishing station 61, and the electromagnet 39 to operate these parts of the jewelry surface cleaning mechanism.

[0040] The moving mechanism 62 is mechanically connected to the clamping mechanism 63 and further mechanically connected to the jewelry to be processed. The traverse seat 19 is slidably connected to the platform plate 2 through the traverse guide rail 18 and is mechanically connected to the moving mechanism 62 .

[0041] The detection mechanism 65 is mechanically connected to the moving mechanism 62 and the clamping mechanism 63 , and electrically communicates with the control system 64 to send the detection status to the control system 64 .
