Description

Technical Field

[0001] The invention belongs to the field of metal electroplating, in particular to a metal shaft hard chromium plating clamping and conveying conductive device. Background Art

[0002] Hard chrome plating of metal shafts is a surface treatment technology. By plating a thicker chromium layer on the surface of the metal shaft, the characteristics of chromium are used to improve its hardness, wear resistance, heat resistance and corrosion resistance. In the process of hard chrome plating of metal shafts, in order to form a uniform and dense chromium plating layer on the surface of the metal shaft, it is generally necessary to first turn on the power to conduct the metal shaft, then electroplating, and finally hard chrome plating of the metal shaft.

[0003] The metal shaft needs to be treated for conductivity before electroplating, and during the conductive process it needs to be clamped and transported to the next processing tool for processing. The existing clamping and conductive device passes through two fixed plates, and a conductive sleeve is set on the surface of the fixed plate. The metal shaft is placed between the two fixed plates and contacts with the conductive sleeve on the surface of the fixed plate. The conductive sleeve is contacted with the metal shaft through transportation and clamped for transportation. Then the conductive structure will transmit electrical energy to the conductive sleeve, thereby conducting electricity to the metal shaft.

[0004] However, if there are impurities or defects on the surface of the metal shaft, these defective parts may hinder the flow of current during the conduction process, causing the current density to increase, the local temperature to rise, and the material on the surface of the metal shaft to melt or vaporize, thereby generating waste and forming impurity particles, which are attached to the surface of the conductive sleeve, causing impurities to adhere to the surface of the conductive sleeve, making the conductive sleeve have poor conductivity for the subsequent metal shaft. In addition, since there is current in the conductive sleeve and its surrounding parts during the process of clamping the metal shaft, the touch operation cannot be performed. The entire device can only be shut down so that the conductive sleeve no longer generates current, and then the conductive sleeve is cleaned and the device is started again after the cleaning is completed. However, this method will greatly affect the working cycle of the device.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0035] Specifically, in order to form a uniform and dense chrome plating layer on the surface of the metal shaft during the hard chrome plating process of the metal shaft, the metal shaft needs to be first subjected to a conductive treatment, and then electroplated, and finally subjected to the hard chrome plating of the metal shaft. The electroplating is completed by an electrolytic reaction in an electrolyte, and an electric current needs to be introduced into the surface of the metal shaft. The metal shaft itself does not have electrical energy, so the metal shaft needs to be subjected to a conductive treatment before electroplating. Before electroplating the metal shaft, the arc surface of the metal shaft needs to be placed on the surface of the conveying roller 22, and then the driving shaft 21 is started to rotate. The driving shaft 21 will rotate with the conveying roller 22, and since the chain 23 connects each driving shaft 21, each driving shaft 21 will rotate, thereby driving The metal shaft is transported in the direction of the clamping structure 4. When the metal shaft moves to the clamping structure 4, it will be located between the two fixed plates 44. At this time, the driving gear 42 is started to rotate, and the driving gear 42 will drive the fixed rack 43 to move. Since the fixed rack 43 is connected to the fixed plate 44, the two fixed plates 44 will move toward one end close to each other. When the conductive sleeve 45 located on the surface of the fixed plate 44 contacts the metal shaft, the driving gear 42 will stop rotating. Since the metal shaft has been fixed by the two fixed plates 44, the moving frame 41 is started to slide on the upper end of the base frame 1. The moving frame 41 will move with the metal shaft, and then the metal shaft will be separated from the surface of the conveying roller 22. At this time, the conductive structure 3 Electric energy will be transmitted to the conductive sleeve 45, so as to conduct electricity to the metal shaft. Since the movable frames 41 are in groups of two, when the movable frame 41 at the right end fixes the metal shaft, it will move to the left, so as to transfer the metal shaft to the movable frame 41 on the left. After the transfer is completed, the movable frame 41 on the right will move toward the direction of the transfer device 2 to reset, and the movable frame 41 on the left will send the metal shaft to the inside of the ultrasonic cleaning mechanism 5 for ultrasonic cleaning. After the movable frame 41 on the left sends the metal shaft to the inside of the ultrasonic cleaning mechanism 5, the movable frame 41 on the left will also move toward the direction of the transfer device 2, and the movable frame 41 on the left will reset. Since each device is set between The conveying roller 22 allows the metal shaft to pass smoothly between each device. After the metal shaft is ultrasonically cleaned, it will continue to be conveyed to the electroplating tank 6. Then, the metal shaft is transferred to the electroplating tank 6 by the conveying roller 22 set between each device. The metal ions are deposited on the surface of the shaft through electrochemical reaction to form a metal coating, which is specifically a process of anodic oxidation and cathodic reduction. The metal on the anode will be oxidized into cations, and the metal ions on the cathode will be reduced into metals. These two processes are carried out simultaneously, so that the metal ions are transferred in the electrolyte solution and precipitated on the cathode to form a uniform metal coating. Then, the metal shaft is rinsed with water through the water washing structure provided in the electroplating tank 6 to complete the electroplating treatment of the metal shaft.However, when the clamping structure 4 is conveying the metal shaft, since the metal shaft will be tightly attached to the surface of the conductive sleeve 45, and the conductive structure 3 will also perform conductive treatment on the metal shaft, if there are defects on the surface of the metal shaft at this time, these defective parts may hinder the flow of current, increase the current density, increase the local temperature, and cause the material on the surface of the metal shaft to melt or vaporize, thereby generating waste, and these wastes will adhere to the surface of the conductive sleeve 45, so that impurities are attached to the surface of the conductive sleeve 45, and the conductive sleeve 45 has a poor conductive effect on the subsequent metal shaft. However, at this time, there is still current in the conductive sleeve 45 and its surrounding parts, and the touch operation cannot be performed. In this case, the existing solution can only shut down the entire device so that the conductive sleeve 45 no longer generates current, and then the conductive sleeve 45 can be cleaned, and the device can be started again after cleaning. However, this method will greatly affect the working cycle of the device. For this reason, a cleaning device 7 is set on the surface of the base frame 1 close to the clamping structure 4. When the movable frame 41 on the right side has completed the transportation of the metal shaft , the right moving frame 41 will move toward the direction of the transfer device 2 to reset, and when the right moving frame 41 is reset, the cleaning frame 713 located inside the base frame 1 is started to rise, and after the cleaning frame 713 is raised, the moving rod 709 is started to slide, so that the moving rod 709 moves toward the right cleaning frame 713, and then the I-shaped magnetic block 710 located on the surface of the moving rod 709 will be stuck in the I-shaped card slot 717 on the inner wall of the cleaning frame 713, and then the moving rod 709 will push the cleaning frame 713 moves toward the right cleaning frame 713, and the abutting brush 725 located on the side wall of the cleaning frame 713 will also abut against the surface of the conductive sleeve 45, so as to clean the conductive sleeve 45, and when the right mobile frame 41 is reset, the moving rod 709 will also move toward the right mobile frame 41, so that the moving rod 709 drives the cleaning frame 713 to reset; by setting the cleaning device 7, the conductive sleeve 45 on the upper end of the mobile frame 41 can be automatically cleaned without powering off the device. ;

[0036] like Figures 1 to 10As shown, the cleaning device 7 also includes: a telescopic cylinder 701, which is arranged below the base frame 1; a clamping ring 702, which is fixedly connected to one end of the telescopic cylinder 701; a fixed frame 705, which slides on the upper surface of the base frame 1; a sliding rod 706, which is fixedly connected to the inside of the fixed frame 705; a sliding ring 707, which slides on the arc surface of the sliding rod 706, and the sliding ring 707 is fixedly connected to the moving rod 709; a limit block 727, which is arranged at the inner center position of the fixed frame 705, and the sliding ring 707 drives the moving rod 709 in the initial state. The movable rod 709 abuts against the surface of the limit block 727; the rotating shaft 726, the rotating shaft 726 is arranged on both sides of the base frame 1; the arc rack 704, the two arc racks 704 rotate on the arc surface of the rotating shaft 726, and the arc rack 704 is meshed with the fixed frame 705; the rotating arm 703, the rotating arm 703 is connected to the two arc racks 704, and the clamping ring 702 is sleeved on the surface of the rotating arm 703; the gear groove 714, the gear groove 714 is opened on one side of the cleaning frame 713; the meshing gear 715, the meshing gear 715 is rotatably connected to the inside of the placement groove 712, and the meshing gear 715 is meshed with the gear groove 714.

[0037] Specifically, after the right moving frame 41 has completed the transfer of the metal shaft, the right moving frame 41 will move toward the direction of the transfer device 2 to reset. When the right moving frame 41 is reset, the meshing gear 715 is started to rotate, and the meshing gear 715 will drive the cleaning frame 713 to move upward, thereby raising the cleaning frame 713 to the surface of the base frame 1. When the meshing gear 715 is rotating, the telescopic cylinder 701 is started, and the telescopic cylinder 701 will drive the arc-shaped racks 704 on both sides of the base frame 1 through the clamping ring 702 to rotate the shaft 726. The center of the circle swings, and at this time, the fixed frame 705 meshing with the arc-shaped rack 704 will also be driven to move in the direction of the right moving frame 41. At this time, the moving rod 709 located inside the fixed frame 705 will abut against the surface of the limit block 727, thereby driving the I-shaped magnetic block 710 to move into the I-shaped slot 717 on the inner wall of the cleaning frame 713, so that the moving rod 709 drives the cleaning frame 713 to move in the direction of the right moving frame 41, and the abutting brushes 725 located on both sides of the cleaning frame 713 will also abut against the conductive sleeve 45, thereby cleaning the surface of the conductive sleeve 45. When cleaning and wiping, and the conductive sleeve 45 above the right movable frame 41 is being cleaned, the movable rod 709 on the left side inside the fixed frame 705 will also be driven to move to the right side, but at this time the movable rod 709 on the left side will slide on the surface of the sliding rod 706 and will not conflict with the movement of the movable rod 709 on the right side. When the movable rod 709 on the right side has finished cleaning the conductive sleeve 45, the telescopic cylinder 701 will drive the arc-shaped rack 704 to reset, and the movable rod 709 on the right side will slide on the surface of the sliding rod 706 and finally abut against the fixed frame 705, thereby driving the cleaning frame 713 to reset through the moving rod 709, so that the cleaning frame 713 moves to the top of the placement slot 712, and the moving rod 709 abuts against the limit block 727 again. If it is necessary to clean the conductive sleeve 45 above the left movable frame 41, it is only necessary to drive the arc-shaped rack 704 to reverse by the telescopic cylinder 701. By setting the moving rod 709 and the cleaning frame 713, the surface of the conductive sleeve 45 above the movable frame 41 can be cleaned of impurities without powering off the clamping structure 4.

[0038] like Figures 2 to 3 As shown, the cleaning frame 713 is disposed inside the base frame 1 , and the cleaning frame 713 will move to the upper surface of the base frame 1 during operation.

[0039] Specifically, the cleaning frame 713 is arranged inside the base frame 1, so that the cleaning frame 713 will not interfere with the transportation of the metal shaft by the clamping structure 4, and impurities and dust on the surface of the metal shaft will not fall into the cleaning frame 713, thereby causing the abutment brushes 725 located on both sides of the cleaning frame 713 to be contaminated.

[0040] like Figure 6 As shown, the arc surface of the sliding rod 706 is sleeved with a return spring 708 , one end of the return spring 708 is fixedly connected to the inner wall of the fixed frame 705 , and the other end of the return spring 708 is fixedly connected to the sliding ring 707 .

[0041] Specifically, when the moving rod 709 cleans the surface of the conductive sleeve 45, after the conductive sleeve 45 is cleaned, the fixed frame 705 will reset the moving rod 709, so that the moving rod 709 will abut against the surface of the limit block 727 again. By setting the reset spring 708, the reset spring 708 can release the elastic force when the fixed frame 705 resets, thereby pushing the sliding ring 707 to abut against the surface of the limit block 727, so that the sliding ring 707 drives the moving rod 709 to reset quickly.

[0042] like Figure 6 As shown, one end of the upper surface of the base frame 1 close to the fixed frame 705 is rotatably connected to a plurality of auxiliary rollers 711 , and the fixed frame 705 slides on the surface of the auxiliary rollers 711 .

[0043] Specifically, when the arc-shaped rack 704 swings, it will drive the fixed frame 705 to move. At this time, a plurality of auxiliary rollers 711 are set at the lower end of the fixed frame 705, so that when the fixed frame 705 slides on the surface of the auxiliary rollers 711, the friction between the fixed frame 705 and the base frame 1 is reduced, thereby reducing the wear of the fixed frame 705.

[0044] like Figures 6 to 10 As shown, an inner wall of the I-shaped slot 717 is provided with an electro-permanent magnet block 718 , and the electro-permanent magnet block 718 is in contact with the I-shaped magnet block 710 .

[0045] Specifically, when the moving rod 709 drives the I-shaped magnetic block 710 to move toward the inner wall of the I-shaped slot 717, the I-shaped magnetic block 710 will eventually come into contact with the electric permanent magnet block 718. At this time, the electric permanent magnet block 718 is powered, and the electric permanent magnet block 718 will absorb the I-shaped magnetic block 710, so that the moving rod 709 will not be detached when driving the cleaning frame 713, and when the moving rod 709 drives the cleaning frame 713 to reset, when the cleaning frame 713 is located directly above the placement slot 712, the power supply to the electric permanent magnet block 718 will be stopped, so that the moving rod 709 and the cleaning frame 713 are no longer fixed, thereby facilitating the cleaning frame 713 to move to the placement slot 712 again.

[0046] like Figures 7 and 8As shown, the two cleaning frames 713 are connected to each other, the inner wall of the right cleaning frame 713 is fixedly connected with a telescopic frame 720, and a positioning rod 721 is provided at the upper end of the telescopic frame 720. The inner wall of the left cleaning frame 713 is fixedly connected with a connecting frame 719, and a groove is provided on the surface of the connecting frame 719, and the positioning rod 721 slides on the inner wall of the groove on the surface of the connecting frame 719, and the initial position of the positioning rod 721 is located on the left side of the groove on the surface of the connecting frame 719.

[0047] Specifically, when the moving rod 709 drives the cleaning frame 713 on the right to clean the conductive sleeve 45, due to the movement of the telescopic frame 720 and the cleaning frame 713 on the left will not move, the positioning rod 721 will slide on the inner wall of the groove on the surface of the connecting frame 719, and will eventually stop at the end of the groove. Then, when the cleaning frame 713 on the right is reset, the positioning rod 721 will also move to the initial position of the groove on the surface of the connecting frame 719. The cleaning frame 713 on the left will also do the same when cleaning the conductive sleeve 45. By connecting the two cleaning frames 713, the moving trajectory of the cleaning frame 713 during cleaning will not be offset, and the reset of the cleaning frame 713 after cleaning can be more precise.

[0048] like Figures 7 and 8 As shown, a limit buckle 728 is provided on one end of the upper surface of the connecting frame 719 close to the left cleaning frame 713 , and the limit buckle 728 and the positioning rod 721 abut against each other.

[0049] Specifically, when the two cleaning frames 713 move to the initial position, the positioning rod 721 can accurately move the cleaning frame 713 to the top of the placement slot 712. However, if the positioning rod 721 cannot be fixed, the positioning effect will be poor. For this reason, a limit buckle 728 is provided on the upper surface of the connecting frame 719 to fix the positioning rod 721 in the initial position, so that the positioning rod 721 can be accurately reset. Embodiment 2

[0050] like Figures 9 and 10 As shown, in contrast to Example 1, another implementation of the present invention is that a collecting frame 716 is provided inside the placement groove 712 , and a plurality of snap-in strips 722 are provided on the surface of the collecting frame 716 , and the snap-in strips 722 are in contact with the abutting brush 725 .

[0051] Specifically, after the conductive sleeve 45 is cleaned, the cleaning frame 713 needs to be moved to the placement groove 712 again. By setting a collecting frame 716 inside the placement groove 712, when the cleaning frame 713 moves downward, the abutment brushes 725 located on both sides of the cleaning frame 713 will abut against the clamping strips 722 on the surface of the collecting frame 716, which can not only collect impurities stuck on the surface of the abutment brush 725, but also ensure that there are no impurities stuck on the surface of the abutment brush 725 each time the abutment brush 725 is used.

[0052] like Figures 9 and 10 As shown, coil springs 723 are provided on both sides of the rotating rod 724, and the initial state of the coil springs 723 is a relaxed state.

[0053] Specifically, by arranging coil springs 723 on both sides of the rotating rod 724, when the abutment brush 725 abuts against the clamping strip 722 on the surface of the collecting frame 716, the elastic force can be released by the coil spring 723, thereby cleaning the impurities on the surface of the abutment brush 725. After the impurities on the surface of the abutment brush 725 are cleaned, the coil spring 723 can also release the elastic force to drive the abutment brush 725 to quickly return to its original position.

[0054] Working principle: Before electroplating the metal shaft, it is necessary to place the metal shaft on the surface of the conveyor roller, and then start the driving shaft to rotate. The driving shaft will rotate with the conveyor roller, and because the chain connects each driving shaft, each driving shaft will rotate, thereby driving the metal shaft to be transported in the direction of the clamping structure. When the metal shaft moves to the clamping structure, it will be located between the two fixed plates. At this time, the driving gear is started to rotate, and the driving gear will drive the fixed rack to move. Since the fixed rack is connected to the fixed plate, the two fixed plates will move toward the end close to each other. When the conductive sleeve on the surface of the fixed plate contacts the metal shaft, the driving gear The metal shaft will stop rotating, and then the metal shaft will leave the surface of the conveying roller. At this time, the conductive structure will transmit electrical energy to the conductive sleeve, thereby conducting electricity to the metal shaft. Since the mobile frames are in groups of two, when the mobile frame on the right end fixes the metal shaft, it will move to the left, thereby transferring the metal shaft to the mobile frame on the left. After the transfer is completed, the mobile frame on the right will move toward the direction of the transfer device to reset. During the resetting of the mobile frame, the meshing gear is started to rotate, and the meshing gear will drive the cleaning frame to move upward, thereby raising the cleaning frame to the surface of the base frame, and while the meshing gear is rotating, the telescopic cylinder is started to telescope. The cylinder will drive the arc-shaped racks on both sides of the base frame to swing with the rotating shaft as the center through the clamping ring, and at this time, the fixed frame meshed with the arc-shaped rack will also be driven to move in the direction of the right moving frame. At this time, the moving rod located inside the fixed frame will abut on the surface of the limit block, thereby driving the I-shaped magnetic block to move into the I-shaped slot on the inner wall of the cleaning frame, so that the moving rod drives the cleaning frame to move in the direction of the right moving frame, and the abutting brushes located on both sides of the cleaning frame will also abut against the conductive sleeve, thereby cleaning and wiping the surface of the conductive sleeve, and when the conductive sleeve above the right moving frame is cleaning, the moving brush located on the left side of the fixed frame The moving rod will also be driven to move to the right, but at this time the moving rod on the left will slide on the surface of the sliding rod and will not conflict with the movement of the moving rod on the right. When the moving rod on the right finishes cleaning the conductive sleeve, the telescopic cylinder will drive the arc-shaped rack to reset, and the moving rod on the right will slide on the surface of the sliding rod, and will eventually abut against the right side of the inner wall of the fixed frame, thereby driving the cleaning frame to reset through the moving rod, so that the cleaning frame moves to the top of the placement slot, and the moving rod abuts against the limit block again. If the conductive sleeve above the left moving frame needs to be cleaned later, it is only necessary to make the telescopic cylinder drive the arc-shaped rack to reverse.By setting the moving rod and the cleaning frame, the surface of the conductive sleeve above the moving frame can be cleaned of impurities in the clamping structure without powering off, and the metal shaft will be sent to the inside of the ultrasonic cleaning mechanism for ultrasonic cleaning. After the metal shaft is ultrasonically cleaned, it will continue to be transported to the electroplating tank, and then the metal shaft will be sent to the electroplating tank for electroplating, and then rinsed with water through the water washing structure in the electroplating tank, thus completing the electroplating treatment of the metal shaft. ;
