Description

Technical Field

[0002] Electroplating is the process of plating a thin layer of other metals or alloys on certain metal surfaces using the principle of electrolysis. It is a process that uses electrolysis to adhere a layer of metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (copper sulfate, etc.) and enhancing aesthetics.

[0003] A special form of electroplating is local electroplating, which is mainly used to achieve different effects on different parts of the surface of the workpiece.

[0004] At present, when parts are partially electroplated, several products are usually fixed in a profiling fixture, and then the profiling fixture is manually operated to clamp the products.

Example

[0041] like Figure 1-11As shown, a spot plating wheel mechanism includes a wheel spot plating mold 8, a feeding chute 3, a clamping mechanism 6, a driving mechanism 4 and an air jet unloading member. A plurality of sample slots 822 are spaced apart on the circumference of the wheel spot plating mold 8, and each sample slot 822 is provided with at least one spot plating opening 8231. The feeding chute 3 is close to the wheel spot plating mold 8, and the sample 2 falls into the sample slot 822 through the feeding chute 3; one end of the spot plating jet 20 is placed in the wheel spot plating mold 8, and the sample 2 on the wheel spot plating mold 8 is electroplated through the spot plating opening 8231, and the other end extends out of the wheel spot plating mold 8, and the spot plating jet 20 is rotatably connected to the wheel spot plating mold 8. The clamping mechanism 6 is partially sleeved on the wheel spot plating mold 8 corresponding to the spot plating jet 20, and is used to clamp the sample 2 and seal it with the spot plating opening 8231. The driving mechanism 4 is transmission-connected to the wheel spot plating mold 8. One end of the jet unloading piece is inserted into the wheel spot plating mold 8 through the rotation center of the wheel spot plating mold 8, and is bent to extend toward the circumferential side of the wheel spot plating mold 8, so as to jet out the sample 2 pasted in the sample groove 822.

[0042] like Figure 2 , which is a schematic diagram of a use and installation structure of the present invention. A spot plating wheel mechanism of the present invention is installed on a machine body 19. Specifically, a processing chamber 191 for accommodating a spot plating wheel mechanism of the present invention is provided on the machine body 19.

[0043] like Figure 2 As described above, a support base plate 5 and a fixing plate 7 are installed in the processing chamber 191, and the support base plate 5 is connected to the machine body 19 via a plurality of support columns 1. The plurality of support columns 1 are used to support and install the support base plate 5.

[0044] like Figure 1-3 As shown, the support base plate 5 is used to support and install the clamping mechanism 6, the spot plating injection piece 20 and the driving mechanism 4. The wheel-type spot plating mold is rotatably installed on the spot plating injection piece 20. When the driving mechanism 4 drives the wheel-type spot plating mold, the wheel-type spot plating mold can rotate relative to the spot plating injection piece 20.

[0045] The sample is guided to the wheel-type spot plating mold in the feeding slide 3 to realize automatic sample loading.

[0046] like Figure 1 As shown, the feed slide is installed in a downwardly inclined manner. The sample 2 can slide freely downward along the feed slide, and the sample sliding out of the feed slide falls into the sample slot 822 on the wheel-type spot plating mold.

[0047] like Figure 1 As shown, the feeding chute is a square structure. In order to facilitate viewing of the samples in the feeding chute, an observation slot can be provided along the length of the feeding chute, through which the state and quantity of the samples in the feeding chute can be quickly known.

[0048] It is understandable that one positional relationship between the feed chute and the wheel-type spot plating mold is that the longitudinal center line of the feed chute and the rotation axis of the wheel-type spot plating mold are perpendicular to each other.

[0049] Working method: The driving mechanism 4 drives the wheel spot plating mold to rotate, and the sample slides onto the sample slot 822 of the wheel spot plating mold through the feeding slide. The sample rotates with the wheel spot plating mold to the clamping mechanism. The clamping mechanism squeezes the sample to fit on the wheel spot plating mold, and the spot plating injection part 20 performs local electroplating on the sample through the spot plating port 8231 to obtain a spot-plated product.

[0050] The wheel-type spot plating mold 8 drives the electroplated sample to rotate to disengage from the clamping mechanism. The sample is separated from the wheel-type spot plating mold under its own gravity and falls onto the sample conveyor belt below, and then the sample is taken away by the conveyor belt.

[0051] When samples appear on the wheel spot plating mold and cannot be unloaded from the wheel spot plating mold by themselves, the jet unloading part will spray air at the samples retained in the wheel spot plating mold to blow the samples out of the wheel spot plating mold, which can effectively ensure that there are no electroplated samples on the wheel spot plating mold, allowing the electroplating work to proceed smoothly.

[0052] In some optional embodiments, a structure of a clamping mechanism is provided. Figure 3 As shown, the clamping mechanism 6 includes at least three auxiliary roller members and a clamping transmission belt 62, wherein at least two auxiliary roller members are spaced apart from each other and installed close to the wheel-type spot plating mold 8, and the remaining auxiliary roller members are installed at intervals and distributed. The clamping transmission belt 62 is tangentially closed and transmission-connected with at least three auxiliary roller members, and is tightly sleeved on the circumferential surface of the wheel-type spot plating mold 8 corresponding to the spot plating injection member 20.

[0053] The number of auxiliary roller members installed can be 3, 4, 5, 6, 7, 8, 9 or 10, etc. A suitable number of auxiliary roller members can be selected for installation according to work needs.

[0054] like Figure 1 , 3 As shown, a number of auxiliary roller components and a distributed installation structure are provided. The number of auxiliary roller components installed is 4. The 4 auxiliary roller components are distributed and installed on the supporting bottom plate 5. The auxiliary roller components may include 2 first auxiliary roller components 61 and 2 second auxiliary roller components 63. The 2 second auxiliary roller components 63 are installed close to the wheel-type spot plating mold 8 at intervals, and the 2 first auxiliary roller components 61 may be installed away from the wheel-type spot plating mold 8.

[0055] The two second auxiliary roller members 63 squeeze the compression belt 62 located between the two second auxiliary roller members 63 onto the wheel-type spot plating mold 8 .

[0056] It is understandable that when the wheel-type spot plating mold 8 rotates, the clamping transmission belt 62 is driven to move, and multiple auxiliary roller members support the clamping transmission belt to form a closed transmission, so that the clamping transmission belt always remains in close connection with the wheel-type spot plating mold 8.

[0057] like Figure 3 As shown, a structure of the first auxiliary roller member is given. The first auxiliary roller member 61 includes a first adjustment shaft 611, a first adjustment nut 612, a first roller 613, a first spring 614, a first support shaft 615 and a first base 616. The first base 616 is mounted with a first support shaft 615, and the first spring 614, the first roller 613 and the first adjustment nut 612 are sleeved on the first support shaft 615 in sequence, and the first adjustment nut 612 is threadedly connected to the first support shaft 615. The first spring 614 supports the first roller 613. The first adjustment nut 612 can move along the first support shaft 615 by screwing the first adjustment nut 612.

[0058] like Figure 3 As shown, a connection structure between the first support shaft and the first adjusting nut is provided. A first adjusting shaft 611 is provided on the top of the first support shaft 615 , and the first adjusting shaft 611 is provided with threads for threaded connection with the first adjusting nut 612 .

[0059] In order to prevent the first adjusting nut from loosening, two first adjusting nuts may be installed at the same time. The two first adjusting nuts are used together to prevent the first adjusting nuts from loosening during vibration.

[0060] like Figure 3 As shown in the figure, a structure of the second auxiliary roller member is given. The second auxiliary roller member 63 includes a second adjustment shaft 631, a second adjustment nut 632, a second roller 633, a second spring 634, a second support shaft 635 and a second base 636. The second base 636 is mounted with a second support shaft 635, and the second spring 634, the second roller 633 and the second adjustment nut 632 are sleeved on the second support shaft 635 in sequence, and the second adjustment nut 632 is threadedly connected to the second support shaft 635. The second spring 634 supports the second roller 633. The second adjustment nut 632 can move along the second support shaft 635 by screwing the second adjustment nut 632.

[0061] like Figure 3 As shown, a connection structure between the second support shaft and the second adjusting nut is provided. A second adjusting shaft 631 is provided on the top of the second support shaft 635 , and the second adjusting shaft 631 is provided with threads for threaded connection with the second adjusting nut 632 .

[0062] In order to prevent the second adjusting nut from loosening, two second adjusting nuts can be installed at the same time. The two second adjusting nuts are used together to prevent the second adjusting nuts from loosening during vibration.

[0063] It is understandable that the first roller 613 can rotate relative to the first support shaft 615. The second roller 631 can rotate relative to the second support shaft 635.

[0064] In some optional embodiments, in order to prevent the sample from moving with the compacting belt, a scraper 18 is additionally installed. The scraper 18 is close to the compacting belt 62 and is used to remove the sample 2 attached to the compacting belt 62.

[0065] The pressing belt presses the sample onto the wheel-type spot plating mold for local electroplating. When the sample moves with the pressing belt, the sample moves and touches the scraper 18, and the scraper 18 blocks the sample from moving with the pressing belt, so that the sample is separated from the pressing belt, achieving the purpose of scraping.

[0066] In some embodiments, a structure of a scraper is provided. Figure 1 As shown, the scraper 18 includes a first support shaft 183, a scraper plate 181, a support rod 185 and a limiting spring 184. A support cylinder 182 is rotatably mounted on the first support shaft 183; one end of the scraper plate 181 is close to the pressing transmission belt 62, and the other end is connected to the support cylinder 182; the support rod 185 is arranged in parallel with the first support shaft 183; one end of the limiting spring 184 is connected to the support rod 185, and the other end is connected to the scraper plate 181.

[0067] The support tube 182 is sleeved on the first support shaft 183, so that the scraper plate 181 can rotate relative to the first support shaft 183 with the help of the support tube 182, so that the scraper plate can swing.

[0068] like Figure 1 As shown, a structural structure of the scraper is provided, and a fixing plate 7 is additionally installed. The fixing plate 7 is aligned with the supporting bottom plate 5 and installed on the machine body 19, and the fixing plate 7 is used to support and install the scraper.

[0069] It should be noted that one installation structure of the scraper plate is that the scraper plate and the pressing belt are installed in an inclined manner. It is understandable that the angle between the moving direction of the scraper plate and the pressing belt is an acute angle. This can facilitate the scraper plate to be inserted between the pressing belt and the sample, so that the sample can be scraped off quickly.

[0070] The limiting spring 184 can limit the scraper plate 181 to stay close to the compression transmission belt, so that the scraper plate can effectively scrape off the sample attached to the compression transmission belt. It can be understood that the limiting spring is elastic. When the sample on the scraper plate presses the scraper plate, the scraper plate can move slightly, and the limiting spring produces elastic deformation and has elastic potential energy to avoid hard contact with the sample and scratching the sample. When the sample is separated from the compression transmission belt, the elastic potential energy of the limiting spring pushes the scraper plate to move in the opposite direction and reset.

[0071] It should also be noted that when the scraper plate is supported on the compression belt, the compression belt protrudes away from the support tube, which is conducive to forming a gap between the compression belt and the sample at the protrusion, thereby allowing the scraper plate to be inserted more smoothly between the compression belt and the sample.

[0072] In some optional embodiments, in order to facilitate the adjustment of the compression between the compression belt and the wheel-type spot plating mold, a tension adjustment mechanism 17 is additionally installed. The tension adjustment mechanism 17 is tangentially connected to the compression belt 62 and is used to adjust the compression between the compression belt 62 and the wheel-type spot plating mold 8.

[0073] It is understandable that the tension adjustment mechanism can solve the problem of the compression conveyor belt becoming loose after long-term operation. In addition, the tension adjustment mechanism can also adjust the compression degree of the compression conveyor belt and the wheel-type spot plating mold for samples of different thicknesses.

[0074] In some embodiments, a structure of a tension adjustment mechanism is provided. Figure 4 As shown, the tension adjustment mechanism 17 includes a shaft seat 1710, a swing rod 178 and a push rod 175. The shaft seat 1710 is installed with a fixed shaft 179. The swing rod 178 is rotatably installed on the fixed shaft 179, with a support 176 installed on one end and a vertical shaft 1711 installed on the other end. The vertical shaft 1711 is sleeved with a support spring 1715, a third roller 1712, and a third adjustment nut 1713 in sequence, and the third adjustment nut 1713 is threadedly connected to the vertical shaft 1711. One end of the push rod 175 is movably connected to the adjustment rod 174, and the other end is provided with a collar 177, which is sleeved on the support 176; the adjustment rod 174 is penetrated by a limiting block 171, and nuts are installed on both sides of the limiting block 171, and the nuts are threadedly connected to the adjustment rod 174.

[0075] The nut includes a first nut 172 and a second nut 173 . The first nut 172 and the second nut 173 are threadedly mounted on the adjustment rod 174 and are located on different sides of the limiting block 171 .

[0076] It is understandable that by screwing the first nut 172 and the second nut 173 , the first nut 172 and the second nut 173 can move along the adjustment rod 174 .

[0077] A connection structure between the vertical shaft 1711 and the third adjusting nut 1713: the vertical shaft 1711 is provided with a third adjusting rod 174, the third adjusting rod 174 is provided with a threaded section, and the third adjusting nut is threadedly connected to the third adjusting rod.

[0078] The support spring 1715 supports the third roller 1712 and sleeves it on the vertical shaft 1711, which can provide a shock-absorbing effect for the third roller. The position of the third roller 1712 on the vertical shaft can be adjusted by screwing the third adjustment nut 1713, so as to adjust the height of the third roller on the vertical shaft.

[0079] It should be noted that two third adjusting nuts can be installed to achieve a better self-locking effect and prevent the third adjusting nut from loosening when vibrated.

[0080] One way to adjust the nut: like Figure 4 As shown, when reducing the distance between the limiting block 171 and the support 176, the second nut 173 can be first screwed along the adjusting rod 174 to move close to the support 176 to the required distance, and then the first nut 172 is screwed. While the adjusting rod 174 extends toward the side of the limiting block 171 on which the first nut is installed, the adjusting rod pulls the pushing rod 175, and the pushing rod 175 pulls the support 176 through the collar 177. The support 176 drives the swinging rod 178 to swing, and the support 176 swings toward the limiting block 171. While shortening the distance between the limiting block 171 and the support 176, the swinging rod drives the third roller 1712 to swing.

[0081] like Figure 4 As shown, when increasing the spacing between the limiting block 171 and the support 176, the first nut 172 can be first screwed and moved along the adjusting rod 174 in the direction away from the limiting block 171 to the required distance, and then the second nut 172 is screwed. While the adjusting rod 174 extends toward the side of the limiting block 171 on which the second nut is installed, the adjusting rod pushes the pushing rod 175, and the pushing rod 175 pushes the support 176 through the collar 177. The support 176 drives the swing rod 178 to swing, and the support 176 swings in the direction away from the limiting block 171. The swing rod drives the third roller 1712 to swing while increasing the spacing between the limiting block 171 and the support 176.

[0082] It is understandable that by moving the adjustment rod, the position of the third roller 1712 can be changed, and then the position of the tensioning adjustment mechanism supporting the compression transmission belt can be changed, so that the tensioning adjustment mechanism can adjust the compression between the compression transmission belt and the wheel-type spot plating mold.

[0083] In some optional embodiments, a structure of a wheel-type spot plating mold is provided. Figure 5-7As shown, the wheel-type spot plating mold 8 includes a spot plating mold frame 85, a first support ring 81, a second support ring 84 and a driven wheel 83. A plurality of sample rack grooves 851 are circumferentially distributed on the spot plating mold frame 85, each sample rack groove 851 has a through opening 852 at the bottom, and each sample rack groove 851 is used to install a sample rack 82, and the sample rack 82 has a sample groove 822. The first support ring 81 is installed at one end of the spot plating mold frame 85. The second support ring 84 is installed at the other end of the spot plating mold frame 85. The driven wheel 83 is connected to the second support ring 84, and is in transmission connection with the driving mechanism 4.

[0084] A structure of the sample rack 82 includes a rack body 821 , a sample slot 822 is provided on the rack body 821 , a boss 823 is provided in the sample slot 822 , and a plurality of spot-plating openings 8231 are distributed on the boss 823 . The spot-plating openings 8231 are communicated with the through opening 852 .

[0085] like Figure 5 As shown, a mounting structure of the feed barrel 16 and the support base plate 5 is provided, and a shaft sleeve seat 21 is additionally installed. The shaft sleeve seat 21 is installed on the support base plate 5, and the feed pipe passes through the support base plate 5 and the shaft sleeve seat 21 in sequence and then extends and inserts into the wheel-type spot plating mold 8. The feed barrel 16 is fixedly mounted on the support base plate 5 through the shaft sleeve seat 21. The shaft sleeve seat 21 can also play a supporting role for the feed barrel.

[0086] In some optional embodiments, a structure of a spot-plated injection part is provided. Figure 1 , 3 As shown in Figures 8, 9 and 10, the spot plating injection member 20 includes a feed cylinder 16, a spray body 203 and a spray nozzle 204. The feed cylinder 16 is inserted into the wheel-type spot plating mold 8 through the rotation center of the wheel-type spot plating mold 8, and is provided with a spray port 161; the spray body 203 is installed in the feed cylinder 16, and a accommodating space 2031 is provided in the spray body 203, one end of the accommodating space 2031 is provided with a feed port 202, and the other end is provided with a spray port, and the feed port 202 is tightly connected to the spray port 161; the spray nozzle 204 is tightly connected to the spray port.

[0087] It should be noted that a feeding structure of the feeding cylinder includes a feeding pump, and the feeding pump supplies the electroplating solution to the feeding cylinder.

[0088] It is understandable that the feed cylinder does not affect the rotation of the wheel-type spot plating mold.

[0089] One structure of the spray nozzle 204 includes a side plate 2042 and an arc plate 2043. The side plates 2042 are installed on both sides of the arc plate 2043 to form an arc-shaped slot structure. The arc plate 2043 is provided with spray holes 2041 spaced apart in the direction of the arc length.

[0090] A mounting structure for the spray nozzle. The spray nozzle is buckled on the spray port, and a sealing gasket is placed between the spray nozzle and the spray body, and then the spray nozzle is fixed to the spray body by bolts. The sealing gasket can ensure the airtight connection between the spray nozzle and the spray body to prevent the electroplating liquid from leaking from the connection between the spray nozzle and the spray body.

[0091] An installation structure of the ejector and the feeding barrel: an axial hole 201 is provided on the ejector 203, and the ejector 203 is sleeved on the feeding barrel 16 through the axial hole 201. The ejection port 161 on the feeding barrel 16 is aligned with the feed port 202 and is tightly connected.

[0092] Working method: The feed pump is connected to the feed cylinder. The feed pump draws the plating liquid and delivers it to the feed cylinder 16. The feed cylinder 16 sprays the plating liquid into the accommodating space 2031 of the injection body 203 through the spray port 161. The plating liquid in the accommodating space 2031 enters the injection nozzle 204 through the injection port, and the injection hole 2041 on the injection nozzle 204 sprays the plating liquid outward.

[0093] In some optional embodiments, a structure of the jet unloading member is provided. Figure 1 As shown, the jet unloading part includes a branch pipe 14, an air pipe 12 and a laser sensor 11. The branch pipe 14 is placed in the wheel-type spot plating mold 8, and a nozzle 15 is installed at one end; the air pipe 12 is installed with a control valve 13, and is inserted through the rotation center of the wheel-type spot plating mold 8 and connected to the branch pipe 14; the laser sensor 11 is installed close to the wheel-type spot plating mold 8, and is used to monitor whether there is a sample 2 on the sample slot 822. The laser sensor 11 is electrically connected to the control valve 13; when the laser sensor 11 detects that there is a sample 2 on the sample slot 822, the control valve 13 opens, and the nozzle 15 sprays gas to blow the sample out of the sample slot 822; when the optical sensor 11 detects that there is no sample 2 on the sample slot 822, the control valve 13 is closed.

[0094] The wheel-type spot plating mold 8 drives the sample through the clamping mechanism, and the clamping mechanism squeezes the sample into the sample slot. While the wheel-type spot plating mold drives the sample through the area where the clamping mechanism is sleeved, the spot plating jet 20 electroplates the sample. As the wheel-type spot plating mold rotates, the electroplated sample is driven to separate from the clamping mechanism. Under the action of its own weight, the sample can freely separate from the wheel-type spot plating mold. However, some samples are squeezed by the clamping mechanism and tightly fit with the sample slot, causing the sample to be unable to separate from the wheel-type spot plating mold by its own gravity. At this time, the jet unloading part can jet the sample retained on the wheel-type spot plating mold, and can blow the sample away from the wheel-type spot plating mold, so that there is no retained sample on the wheel-type spot plating mold, and avoid the sample retained on the wheel-type spot plating mold affecting the feeding of the feeding slide.

[0095] It should be noted that the gas pipeline 12 can be connected to a gas storage tank or a compressed air station. The gas storage tank and the compressed air station can serve as the gas source of the gas pipeline.

[0096] like Figure 1 As shown, a mounting structure of the laser sensor is provided, with a support base 9 and a suspension 10 being additionally installed. The support base 9 is installed on the support bottom plate 5, and is used to support and install the feed chute 3 and the suspension 10, and the suspension 10 is used to support and install the laser sensor 11.

[0097] It is understandable that a through hole is provided on the bottom surface of the sample holder slot 851 of the spot plating mold frame 85, so that the gas ejected from the nozzle can directly act on the sample.

[0098] Working method: When the laser sensor 11 detects that there are samples 2 retained on the wheel spot plating mold 8, it can send data information to the control valve 13. Upon receiving the data information, the control valve 13 opens, and the pressurized gas in the gas pipe 12 is transported to the branch pipe 14. The pressurized gas in the branch pipe 14 is ejected outward through the nozzle 15. The ejected gas blows the sample, and the sample is subjected to force and then detaches from the wheel spot plating mold.

[0099] The laser sensor 11 monitors that there is no sample on the wheel-type spot plating mold to which it is turned, and the control valve 13 is in a closed state. No gas is ejected out of the nozzle.

[0100] It is understandable that a material guide trough may be installed below the laser sensor to uniformly guide the samples blown out by the jet discharger to the collection box.

[0101] In some optional embodiments, a structure of a driving mechanism is provided. Fig.11 As shown, the driving mechanism includes a driving motor 41, a driving wheel 48 and a driving shaft 45. One end of the driving shaft 45 is drivingly connected to the driving motor 41, and the other end is drivingly connected to the driving wheel 48.

[0102] An installation structure of the drive motor and the machine body: the motor bracket 42 is installed on the machine body 19, the drive motor 41 is installed on one end of the motor bracket 42, the first bearing seat 44 is installed on the other end of the motor bracket 42, the coupling 43 is transmission-connected to the drive motor 41, and the drive shaft 45 passes through the first bearing seat 44 and is transmission-connected to the coupling 43.

[0103] A rotation connection structure between the drive shaft and the support base plate. A second bearing seat 46 is installed on one side of the support base plate 5, and a third bearing seat 47 is installed on the other side corresponding to the second bearing seat 46. The drive shaft 45 passes through the second bearing seat 46, the support base plate 5 and the third bearing seat 47 in sequence and is transmission-connected to the drive wheel 48. The drive shaft is rotationally connected to the second bearing seat 46 and the third bearing seat 47.

[0104] A transmission connection between the driving mechanism and the wheel-type spot plating mold: the driving wheel 48 is meshed and transmission-connected with the driven wheel 83 of the wheel-type spot plating mold 8 . Obviously, various changes and modifications may be made to the present invention by those skilled in the art without departing from the spirit and scope of the present invention. The present disclosure is not limited to the precise structure described above and shown in the accompanying drawings, and various changes and modifications may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims. Thus, if these changes and modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these changes and modifications.
