Description

Technical Field

[0001] The invention relates to the technical field of electrophoretic component spray decontamination, in particular to a torrent spray decontamination treatment process for the surface of an electrophoretic component. Background Art

[0002] Electrophoresis is the abbreviation of electrophoresis phenomenon, which refers to the phenomenon that charged particles move toward the electrode with opposite electrical properties under the action of an electric field. The technology that uses the different moving speeds of charged particles in an electric field to achieve separation is called electrophoresis technology. Through electrophoresis technology, an external electric field can be used to make particles such as pigments and resins suspended in the electrophoresis liquid migrate in a directional manner and deposit on the substrate surface of one of the electrodes. This electrophoresis-based coating method is widely used in industries such as automobiles, building materials, hardware and home appliances. After electrophoretic coating, the workpiece will have stronger strength, adhesion and corrosion resistance. However, the electrophoretic process also has certain limitations. For example, non-conductive objects such as wood and plastic cannot be coated with this coating method. In order to increase the adhesion effect of paint during electrophoresis of the workpiece, the electrophoretic parts need to be sprayed for decontamination pretreatment to remove oil, impurities and rust on the surface of the electrophoretic parts to prevent oil, impurities and rust from affecting the subsequent formation of the phosphating film of the electrophoretic parts and the bonding strength of the electrophoretic coating.

[0003] In the existing patents related to spray treatment, such as the invention patents with publication numbers CN107638979A and CN117139224A, these related patent technologies usually adopt a torrent spraying method to increase the contact area between the water flow and the electrophoretic parts and the spraying intensity in order to increase the decontamination effect during spray decontamination pretreatment. In order to prevent the electrophoretic parts from falling off during torrent spraying, the electrophoretic parts need to be manually fixed on the mobile rack, which is not only time-consuming and labor-intensive, but also causes the fixed points between the electrophoretic parts and the fixed rack to fail to be effectively spray-cleaned during the torrent spray decontamination process on the surface of the electrophoretic parts. The electrophoretic parts need to be rinsed twice, and the entire torrent spray decontamination work on the surface of the electrophoretic parts cannot be completed at one time, which greatly affects the decontamination efficiency and decontamination quality of the torrent spraying on the surface of the electrophoretic parts.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time with the existing treatment process, and even if it can be solved, it needs to be solved with the cooperation of external tools, thus failing to achieve the desired effect. Therefore, we propose a torrent spray decontamination treatment process and treatment device for the surface of electrophoretic parts that can avoid the above problems. Summary of the invention

The threaded connection relationship between the threaded rod 2101 and the sliding frame 2104 can be used to drive the sliding frame 2104 to slide to the left inside the bracket 17.

[0061] Example 3

[0062] When the sliding frame 2104 slides to the left until it contacts the first contact switch 2119, the first contact switch 2119 is closed, and the first electromagnetic clutch 2103 is controlled by the wire to release the transmission, so that the sliding frame 2104 stops at the leftmost position of the bracket 17, and the toggle plate 2134 is also stuck in the L-shaped frame 2131, and the second electromagnetic clutch 2107 is also controlled by the first contact switch 2119. By combining the internal transmission structure of the second electromagnetic clutch 2107, the servo motor 2102 can be The rotating rod 2110 is driven to rotate by the large gear 2108 and the small gear 2109. The rotation of the rotating rod 2110 cooperates with the limiting of the first bevel gear 2114, the second bevel gear 2115 and the limiting frame 2112 to drive the bidirectional screw 2113 to rotate. When the bidirectional screw 2113 rotates, the guide rod 2117 can be driven to slide inside the bracket 17 through the fixing plate 2116, and then the push plate 2118 is used to push the connecting plate 2105 to move downward, forcing the compression spring 2106 to stretch and accumulate elastic force.

[0063] When the connecting plate 2105 moves downward, the limit plate 2132 cooperates with the elastic force provided by the toggle plate 2134 and the tension spring 2133 to limit the position of the L-shaped frame 2131, and then the sliding seat 2125 can be driven to slide upward inside the fixed frame 2124 through the pull rod 2130, and the reset spring 2129 is forced to contract. During the upward sliding of the sliding seat 2125, the movable hinge relationship between the connecting rod 2128 and the clamping frame 2126, and the movable hinge relationship between the clamping frame 2126 and the fixed frame 2124 can be used to drive the clamping frame 2126 to move upward. 126 opens until the connecting plate 2105 drives the fixing frame 2124 and the clamping frame 2126 to move downward to the outside of the workpiece 2123. At this time, the downward pressure is greater than the elastic force of the tension spring 2133, thereby forcing the toggle plate 2134 to swing downward along the hinge point with the limiting plate 2132, releasing the limit on the L-shaped frame 2131, and then using the elastic force of the return spring 2129 to push the sliding seat 2125 to move downward, thereby cooperating with the connecting rod 2128 and the clamping frame 2126 to allow the clamping sleeve 2127 to clamp the workpiece 2123 from the outside;

[0064] At this time, the special bidirectional thread on the bidirectional screw 2113 can drive the fixing plate 2116 and the guide rod 2117 to move upward again, so the compression spring 2106 will also pull the connecting plate 2105 to move upward again until the upper surface of the L-shaped frame 2131 contacts the toggle plate 2134 again, and force the toggle plate 2134 to swing upward to make the L-shaped frame 2131 return to its original position. At this time, the automatic material removal of the workpiece 2123 can be completed. When the left fixing plate 2116 moves upward to contact the second contact switch 2120, the second contact switch 2120 The second electromagnetic clutch 2107 can be controlled to disconnect the first electromagnetic clutch 2103 and close it, and the servo motor 2102 can rotate in the opposite direction, so that the servo motor 2102 can drive the threaded rod 2101 to rotate again through the first electromagnetic clutch 2103, and then the reverse rotation of the servo motor 2102 can drive the sliding frame 2104 and the clamped workpiece 2123 to move to the top of the spray pool 11. At this time, the suction force provided by the water suction pump 14 can be used to draw out the flushing liquid inside the spray pool 11 and spray it to the workpiece 2123 through the multi-way pipe 15 and the spray head 16;

[0065] Since the spray head 16 is at a certain angle and is symmetrically distributed front to back, a torrent spraying flushing and decontamination form can be formed. The sprayed flushing liquid is filtered by the screen 12 and the microporous filter plate 13 and then flows back into the spray pool 11 for recycling. Therefore, when the workpiece 2123 is subjected to torrent spraying, it can be automatically clamped and moved to the top of the spray pool 11 for torrent spraying and decontamination cleaning. The staff only needs to place the workpiece 2123 on the limiting fixture 2122, which increases the convenience of loading the electrophoretic parts during torrent spraying and decontamination, reduces the labor intensity of the staff, and also improves the torrent spraying and decontamination efficiency of the electrophoretic parts.

[0066] Example 4

[0067] See also Figure 2 , Figure 3 and Figure 8 The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The clamping mechanism 2 also includes a clamping switching unit 22. The clamping switching unit 22 is arranged inside the automatic clamping unit 21. The clamping switching unit 22 can switch the clamping mode of the electrophoretic part and eliminate the blind spot of the flood spray.

[0068] As a further limitation of the clamping mechanism 2 of the present invention, the clamping switching unit 22 includes an auxiliary frame 2201, both sides of the auxiliary frame 2201 are fixedly connected to the inner wall of the bracket 17, the upper surface of the auxiliary frame 2201 is fixedly connected to a guide frame 2202, the guide frame 2202 is located above the spray pool 11, the bottom surface of the auxiliary frame 2201 is provided with a guide groove 2203, the front and back sides of the guide frame 2202 are fixedly connected to a ladder frame 2204, and the bottom surface of the connecting plate 2105 is fixedly connected to three positioning cylinders 2205, each The interior of the positioning cylinder 2205 is slidably connected to a moving seat 2206. The outer surface of each positioning cylinder 2205 and the outer surface of each moving seat 2206 are movably hinged to one end of two connecting rods 2207. The other end of each group of connecting rods 2207 is movably hinged to a connecting frame 2208. There are two connecting rods 2207 in each group. A side of each connecting frame 2208 away from the positioning cylinder 2205 is fixedly connected to a clamping plate 2209. The inner bottom wall of each positioning cylinder 2205 is fixedly connected to one end of the positioning spring 2210. The other end of each positioning spring 2210 is fixedly connected to the bottom surface of the moving seat 2206, and the upper surface of each moving seat 2206 is fixedly connected to a movable rod 2211. The top of each movable rod 2211 passes through the connecting plate 2105 and is fixedly connected to a guide block 2212. Both side surfaces of each guide block 2212 are arc surfaces. The side surfaces of each group of L-shaped frames 2131 close to each other are fixedly connected to a sliding rod 2213. The number of each group of L-shaped frames 2131 is two. By setting the clamping switching unit 22, it can be During the torrent spray cleaning process of the workpiece 2123, the clamping and fixing position of the workpiece 2123 is switched back and forth, so that there will be no spray dead angles for the workpiece 2123 during the torrent spray cleaning, and the clamping position on the workpiece 2123 can also be cleaned by the torrent spray, so that the fixed points of the electrophoretic parts can be effectively sprayed and cleaned, and there is no need to rinse the electrophoretic parts for the second time, so that the torrent spray cleaning work of the entire surface of the electrophoretic parts can be completed at one time, which greatly increases the torrent spray cleaning efficiency of the electrophoretic parts and also improves the torrent spray cleaning quality of the electrophoretic parts.

[0069] The specific implementation of this embodiment is as follows: when the sliding frame 2104 moves to the right to above the spray pool 11, the guide block 2212 will first enter the guide groove 2203, and the arc surface of the guide block 2212 will cooperate with the guidance of the guide frame 2202 and the guide groove 2203 to push the movable rod 2211 downward. When the clamping frame 2126 and the clamping sleeve 2127 clamp the workpiece 2123, the positioning cylinder 2205 will also enter the workpiece 2123, but will not contact the workpiece 2123. At this time, when the movable rod 2211 moves downward, it will push the movable seat 2206 downward to slide inside the positioning cylinder 2205, and force the positioning spring 2210 to contract, so that the movable rod 2211 can move downward. During the downward movement of the movable seat 2206, the connecting rod 2207 and the connecting frame 2208 can push the two clamping plates 2209 away from each other and contact the inner wall of the workpiece 2123, so that the workpiece 2123 is clamped inside the workpiece 2123. After the clamping plate 2209 clamps the workpiece 2123, the sliding rod 2213 will contact the ladder frame 2204 and, guided by the inclined surface of the ladder frame 2204, can drive the L-shaped frame 2131 to move upward. As the L-shaped frame 2131 moves upward, in cooperation with the pull rod 2130, the sliding seat 2125 and the connecting rod 2128, the clamping frame 2126 can be unfolded again to release the workpiece 2123, so that the flushing liquid can be The clamping sleeve 2127 is re-positioned to contact the workpiece 2123, and after the sliding rod 2213 is separated from the ladder frame 2204, the clamping sleeve 2127 will clamp the workpiece 2123 again by the elastic force provided by the reset spring 2129. When the guide block 2212 is separated from the guide groove 2203, the clamping plate 2209 is separated from the workpiece 2123 by the push of the positioning spring 2210. Since the ladder frame 2204 is composed of two trapezoids and the guide groove 2203 also has two crests, the internal and external clamping switching of the workpiece 2123 can be performed twice. At the same time, since the two highest points of the ladder frame 2204 have a parallel surface and the guide groove 2203 also has a parallel surface, the internal and external clamping switching of the workpiece 2123 can be performed twice. There are also parallel grooves at both ends at the wave crest, which can ensure that there will be no problem of discontinuity in connection when the workpiece 2123 is switched between internal and external clamping, resulting in the workpiece 2123 falling off. By switching the clamping and fixing position of the workpiece 2123 back and forth, there will be no spraying dead corners for the workpiece 2123 during the flood spray cleaning, so that the clamping position on the workpiece 2123 can also be cleaned by the flood spray, ensuring that the fixed points of the electrophoretic parts can be effectively sprayed and cleaned, without the need for secondary rinsing of the electrophoretic parts, so that the flood spray cleaning work on the entire surface of the electrophoretic parts can be completed at one time, which greatly increases the flood spray cleaning efficiency of the electrophoretic parts, and also improves the flood spray cleaning quality of the electrophoretic parts.

[0070] Example 5

[0071] See also Fig. 9 and Fig.10 , the present invention provides a technical solution:

[0072] The present invention makes corresponding improvements to the technical problems mentioned in the background technology. A feeding mechanism 3 is arranged on the right side of the automatic clamping unit 21. The feeding mechanism 3 is used together with the clamping mechanism 2 to automatically feed the electrophoretic parts after the torrent spraying.

[0073] As a further limitation of the unloading mechanism 3 of the present invention, the unloading mechanism 3 includes a support platform 301, the support platform 301 is located on the right side of the spray pool 11, the upper surface of the support platform 301 is fixedly connected to the limiting cover 302, the inner rotatable connection of the limiting cover 302 is connected to the fixing rod 303, the outer surface of the fixing rod 303 is fixedly connected to the clamping frame 304, the clamping frame 304 is located inside the limiting cover 302, one end of the threaded rod 2101 is fixedly connected to the third bevel gear 305, the upper surface of the support platform 301 is rotatably connected to the transmission rod 306, the top of the transmission rod 306 is fixedly connected to the fourth bevel gear 307, the outer surface of the fourth bevel gear 307 is meshed with the outer surface of the third bevel gear 305, the upper surface of the support platform 301 is rotatably connected to the stabilizing column 308, the outer surface of the stabilizing column 308 and the transmission rod 3 The outer surface of 06 is jointly sleeved with a pulley 309, the outer surface of the stabilizing column 308 is fixedly connected to an incomplete gear 310, the outer surface of the fixing rod 303 is fixedly connected to a transmission gear 311, the outer surface of the transmission gear 311 meshes with the outer surface of the incomplete gear 310, and the upper surface of the auxiliary frame 2201 is fixedly connected to two trapezoidal blocks 312, and the two trapezoidal blocks 312 are both located above the limiting cover 302. By setting up a feeding mechanism 3, the workpiece 2123 that has been decontaminated by the torrent spraying can be automatically unloaded, and there is no need for the staff to manually remove the workpiece 2123, which can not only prevent the workpiece 2123 from being contaminated again during the manual removal of the workpiece 2123, but also further reduce the labor intensity of the staff, making the unloading work of the electrophoretic parts in the torrent spraying decontamination process also very convenient and quick;

[0074] The outer surface of the transmission rod 306 is rotatably connected with a stabilizing plate 315, and the right side of the stabilizing plate 315 is fixedly connected to the inner side wall of the bracket 17. The stabilizing plate 315 can locate the position of the transmission rod 306, increase the stability of the transmission rod 306 when rotating, and prevent the transmission rod 306 from excessive swinging during the transmission process;

[0075] The bottom surface of the support platform 301 is fixedly connected with two second support legs 313, and the bottom surfaces of the two second support legs 313 are provided with two second mounting through holes 314. The second support legs 313 can support and stabilize the position of the support platform 301, so that the support platform 301 can maintain a suitable height. The second mounting through holes 314 can cooperate with bolts and other fixing parts to install the second support legs 313 and the support platform 301 at the required working position.

[0076] The specific implementation of this embodiment is as follows: when the sliding frame 2104 moves to the right above the support platform 301, the sliding rod 2213 will contact the trapezoidal block 312, and through the guidance of the inclined surface of the trapezoidal block 312, it can drive the L-shaped frame 2131 to move upward. As the L-shaped frame 2131 moves upward, in conjunction with the pull rod 2130, the sliding seat 2125 and the connecting rod 2128, the clamping frame 2126 can be re-expanded, thereby releasing the workpiece 2123, allowing the workpiece 2123 to fall into one of the clamping frames 304. In the clamping groove, when the workpiece 2123 falls into the gap between the clamping frame 304 and the limiting cover 302, the rotation of the threaded rod 2101 can cooperate with the third bevel gear 305 to drive the fourth bevel gear 307 to rotate, and then cooperate with the support platform 301 to drive the transmission rod 306 to rotate. When the transmission rod 306 rotates, it can cooperate with the pulley 309 to drive the stabilizing column 308 and the incomplete gear 310 to rotate. The incomplete teeth on the incomplete gear 310 can drive the transmission gear 311 and the fixing rod 303 to rotate a certain distance. The clamping frame 304 is rotated at the same angle to move the workpiece 2123 that falls into the limiting cover 302 to another position, and the card slot position on the other clamping frame 304 is moved to below the trapezoidal block 312, until the workpiece 2123 after three flood sprayings falls into the limiting cover 302. Finally, with the rotation of the clamping frame 304, the workpiece 2123 that has been cleaned can enter the next processing step of the workpiece 2123 through the discharge on the limiting cover 302, which can make the flood spraying decontamination completed. The workpiece 2123 is unloaded automatically, and there is no need for the staff to manually remove the workpiece 2123. This not only prevents secondary contamination of the workpiece 2123 during the manual removal of the workpiece 2123, but also further reduces the labor intensity of the staff, making the unloading work in the electrophoretic part flood spray decontamination process also very convenient and quick. Finally, it is only necessary to let the servo motor 2102 reverse again to move the sliding frame 2104 and the connecting plate 2105 to the left, so that the next workpiece 2123 flood spray decontamination work can be carried out.

[0077] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
