Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, and more specifically, to a multi-point, one-time fully automatic resist coating device for injection molded parts. Background Technology

[0002] Before plastic parts enter the chemical plating and electroplating tanks, the areas that are "unwanted to be coated" are precisely sealed with a plating inhibitor, thereby achieving effects such as local electroplating, two-color electroplating, and transparent electroplating.

[0003] Chinese Patent Publication No. CN216396958U discloses a hydrophobic paint coating device for flexible metal parts, including an outer frame. A sliding seat is provided at the lower inner end of the outer frame, and a hydrophobic paint tank is provided on the upper side of the sliding seat. A coating roller is rotatably connected to the inner side of the hydrophobic paint tank via a bearing. A guide roller is rotatably connected to the inner wall of the upper end of the outer frame. A blower fan is provided at one end of the upper surface of the outer frame and at the upper end of the outer surface of the outer frame. A guide tube is provided on the inner side of the outer frame corresponding to the blower fan, and the position of the guide tube corresponds to the position of the guide roller.

[0004] The above technical solution blows excess hydrophobic paint down into the hydrophobic paint tank and dries the hydrophobic paint on the surface of the flexible metal strip, thereby reducing the phenomenon of hydrophobic paint dripping onto the outside. However, in the local electroplating process of injection molded parts, it is necessary to apply a resist solution (resist oil) to the areas that do not need to be plated before electroplating. The geometry of existing injection molded parts is becoming increasingly complex, and their surfaces often have height differences and irregular curved surfaces, resulting in the non-collinear distribution of the points to be coated in space. Currently, most of the spray needles in the industry adopt a fixed installation structure, which lacks self-adjustment capability. Since the spatial distance between the spray needle and different spray points is dynamic... The spray distance is constantly changing and cannot be kept constant. When the distance between the spray needle and a certain spray point is too large, the resist oil is easily affected by airflow interference and atomized and scattered during its journey from the nozzle to the surface of the workpiece. This results in blurred coating edges, inaccurate positioning, and even false spraying or missed spraying. Conversely, when the spray distance is too small, the high-pressure sprayed resist oil directly impacts the uneven surface of the injection molded part, which will produce the phenomenon of "slurry bursting" (i.e., resist oil splashing or accumulating). This not only damages the uniformity and density of the coating, but may also contaminate the electroplated area or surrounding equipment, affecting the coating quality and effect of the injection molded part. Summary of the Invention

One of the side frames is fixedly mounted on a mounting bracket, and a motor is fixedly mounted on the surface of the mounting bracket.

[0009] Preferably, the surface of the injection molded part body is provided with a suspension rod for suspending it, and the suspension rod is suspended on a lifting device.

[0010] Preferably, the first and second rotating frames are located between two spraying devices. Multiple telescopic devices are fixedly installed on the inner side of the spraying devices. A connecting plate is fixedly installed on the telescopic end of the telescopic device, and the top of the connecting plate is fixedly connected to the surface of the sprayer.

[0011] Preferably, an inlet pipe is fixedly installed on the outer surface of each of the valve blocks, and a sliding groove is opened on the inner side of each of the two spraying frames. The slide frame is slidably connected in the sliding groove, and the slide frame is slidably connected to the spraying frame through the sliding groove.

[0012] Preferably, both of the crossbars are rotatably connected to lead screws, which are threaded to the bottom of the spraying equipment. Both of the crossbars are fixedly mounted with motors on their side surfaces, and the output ends of the motors are fixedly connected to the lead screws.

[0013] Preferably, a base is provided below the spraying frame, and a vertical frame is fixedly installed on the surface of the base. Two spraying frames are respectively fixedly installed on both sides of the vertical frame. A telescopic rod one is fixedly installed on the inner side of the vertical frame. The telescopic end of the telescopic rod one is fixedly connected to the surface of one of the slides. A telescopic rod two is fixedly installed on the inner side of the ends of the two spraying frames. The telescopic end of the telescopic rod two is fixedly connected to the surface of the other slide.

[0014] Preferably, a solenoid valve assembly is fixedly installed on the inner side of the vertical frame, a pump body is fixedly installed on the top surface of the vertical frame, a placement box is fixedly installed on the inner side of the vertical frame, the placement box is located above the solenoid valve assembly, the inlet of the pump body is connected to the placement box through a hose, the outlet of the pump body is connected to the solenoid valve assembly through a pipeline, and multiple outlets of the solenoid valve assembly are connected to multiple inlet pipes through hoses.

[0015] Preferably, a fixing frame is symmetrically fixedly installed on the bottom surface of the two spraying racks, a plurality of recycling ports are fixedly installed on the surface of the fixing frame, a manifold is fixedly installed in the middle of the bottom surface of the fixing frame, a plurality of return pipes connected to the circuit are fixedly installed on both sides of the spraying equipment, the return pipes are connected to the recycling ports through flexible hoses, a recycling bin is placed on the surface of the base, and the manifold is connected to the recycling bin through flexible hoses.

[0016] Preferably, a controller is fixedly installed on the surface of the vertical frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) This multi-point, one-time fully automatic resist plating liquid coating device for injection molded parts controls the extension and retraction of the retractable sprayer to ensure that the distance between all sprayer nozzles and all coating locations on the injection molded part body is the same. Compared with traditional coating devices, this spraying equipment uses a retractable sprayer, which ensures that the distance between multiple sprayers and multiple coating locations on the injection molded part body is the same. Under the same pump pressure, the sprayer can complete the coating of the injection molded part body. This not only solves the problems of blurred coating edges, inaccurate positioning, false spraying, and missed spraying when the distance between the spray needle and the spraying point is too large, but also solves the problem of resist plating liquid splashing instantly upon contact with the injection molded part body surface when the distance between the spray needle and the spraying point is too small, thus improving the coating quality of the injection molded part body.

[0019] 2) When this multi-point, one-time fully automatic resist plating liquid coating device for injection molded parts is in use, during the coating process of the sprayer on the coating position of the injection molded part, the excess resist plating oil reaches the recycling port through multiple return pipes and hoses. The resist plating oil is then collected through the manifold and finally collected into the recycling tank. This prevents the excess resist plating liquid from leaking out and also recycles the resist plating liquid, saving the resources used for resist plating liquid.

[0020] 3) When using this multi-point, one-time fully automatic resist coating device for injection molded parts, the motor rotates, causing the lead screw to rotate. The rotation of the lead screw causes the spraying equipment to move inside the cross frame. When both sides of the injection molded part need to be sprayed, after the two spraying devices have finished moving, their positions correspond to each other. Without flipping the injection molded part, both sides of the injection molded part can be coated simultaneously. When the positions of the two spraying devices are misaligned, multiple injection molded parts can be coated on one side only, further improving the coating efficiency of the injection molded parts.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1 - Figure 9A fully automatic, one-time, multi-point resist plating device for injection molded parts includes two symmetrical spraying frames 1. Two slides 2 are symmetrically slidably connected between the two spraying frames 1. A crossbeam 13 is fixedly installed on the top surface of each of the two slides 2. A spraying device 3 is slidably connected to the surface of each of the two crossbeams 13. The spraying device 3 can adjust the spraying distance between the sprayer 5 and the injection molded part body 11. The spraying device 3 includes multiple horizontally arranged valve blocks 4. The valve blocks 4 are conventional controllable flow valve blocks in the prior art. A retractable sprayer 5 is fixedly installed on the surface of any one of the valve blocks 4. The sprayer 5 is a conventional spray needle in the prior art. The retractable sprayer 5 adjusts the spraying distance to the injection molded part body 11. The side surfaces of the two spraying frames 1 are fixedly equipped with... The device is equipped with two side frames 6, each internally connected to a rotating frame 7 and a rotating frame 8. Rotating shafts 10 are installed between the two ends of rotating frames 7 and 8 and the two side frames 6, allowing them to rotatably connect. Multiple vision sensors 9 are fixedly mounted on the bottom surfaces of both rotating frames 7 and 8. These vision sensors 9 are conventional vision sensors in the prior art. The vision sensors 9 move with rotating frames 7 and 8, enabling a comprehensive scan of the coating points on the injection-molded part body 11. The injection-molded part body 11 to be coated is placed between rotating frames 7 and 8. One of the side frames 6 has a through-hole placement groove 12 on its surface. The rotating frames 7 and 8 rotate in opposite directions, carrying multiple vision sensors 9 to scan and collect data on the coating position of the injection molded part body 11. The coating position data collected by the vision sensors 9 is compared with the coating point data and the distance data between the sprayer 5 and the coating position of the injection molded part body 11 entered by the operator into the controller 37. Telescopic rods 27 and 28 extend, respectively carrying two spraying devices 3 towards the injection molded part body 11. At this time, multiple retractable sprayers 5 follow the spraying devices 3. After initial adjustment of the distance between the multiple retractable sprayers 5 and the injection molded part body 11, the distance between the sprayer 5 and the coating position of the injection molded part body 11 is determined. Due to the uneven surface of the injection molded part body 11... The surface is uneven, and the distance between the coating points on the injection molded part 11 and the sprayer 5 varies. Based on the coating points on the injection molded part 11, the retractable sprayer 5 is controlled to extend and retract, ensuring that the distance between the nozzles of all sprayers 5 and all coating locations on the injection molded part 11 is the same. Compared to traditional coating devices, this spraying equipment 3 uses a retractable sprayer 5, making the distance between multiple sprayers 5 and multiple coating locations on the injection molded part 11 the same. Under the same pump pressure, the sprayers 5 can complete the coating of the injection molded part 11. This not only solves the problems of blurred coating edges, inaccurate positioning, incomplete spraying, and missed spraying when the distance between the spray needle and the spray point is too large, but also solves the problem of insufficient distance between the spray needle and the spray point.The problem of splashing of the resist plating oil upon contact with the surface of the injection molded part 11 has been addressed, thus improving the coating quality of the injection molded part 11.

[0033] Please see Figure 8 and Figure 9 One of the side frames 6 has a gear 14 and a gear 2 15 rotatably connected to its surface. The gear 14 and the gear 2 15 mesh with each other. One of the side frames 6 has a mounting bracket 16 fixedly installed on its surface. The mounting bracket 16 has a motor 17 fixedly installed on its surface. The motor 17 is a conventional forward and reverse reversing motor in the prior art. The output end of the motor 17 is fixedly connected to the gear 14.

[0034] Please see Figure 8 and Figure 9 The surface of the injection molded part body 11 is provided with a suspension rod 18 for suspending it, and the suspension rod 18 is suspended on a lifting device.

[0035] Please see Figure 5 - Figure 7 The first rotating frame 7 and the second rotating frame 8 are located between the two spraying devices 3. Multiple telescopic devices 19 are fixedly installed on the inner side of the spraying device 3. The telescopic devices 19 are conventional electric control push rods in the prior art. A connecting plate 20 is fixedly installed on the telescopic end of the telescopic device 19. The top of the connecting plate 20 is fixedly connected to the surface of the sprayer 5.

[0036] Please see Figure 1 - Figure 6 An inlet pipe 21 is fixedly installed on the outer surface of any valve block 4. A sliding groove 22 is opened on the inner side of each of the two spraying racks 1. The slide 2 is slidably connected in the sliding groove 22. The slide 2 is slidably connected to the spraying rack 1 through the sliding groove 22. The two slides 2 move towards each other, so that the two spraying devices 3 move towards each other, thereby realizing the initial adjustment of the spraying distance of the injection molded part body 11.

[0037] Both crossbars 13 are rotatably connected to lead screws 23, which are threaded to the bottom of the spraying equipment 3. Both crossbars 13 are fixedly mounted with motors 24, which are conventional forward and reverse motors in the prior art. The output end of the motors 24 is fixedly connected to the lead screws 23. The rotation of the motors 24 drives the lead screws 23 to rotate, which causes the spraying equipment 3 to move inside the crossbars 13. When both sides of the injection molded part body 11 need to be sprayed, after the two spraying equipment 3 have moved, their positions correspond to each other. Without flipping the injection molded part body 11, both sides of the injection molded part body 11 can be coated simultaneously. When the positions of the two spraying equipment 3 are misaligned, multiple injection molded parts body 11 can be coated on one side only, further improving the coating efficiency of the injection molded part body 11.

[0038] Please see Figure 1 - Figure 4 A base 25 is provided below the spraying frame 1. A vertical frame 26 is fixedly installed on the surface of the base 25. Two spraying frames 1 are fixedly installed on both sides of the vertical frame 26. A telescopic rod 27 is fixedly installed on the inner side of the vertical frame 26. The telescopic end of the telescopic rod 27 is fixedly connected to the surface of one of the slides 2. A telescopic rod 28 is fixedly installed on the inner side of the ends of the two spraying frames 1. The telescopic end of the telescopic rod 28 is fixedly connected to the surface of the other slide 2. The telescopic rod 28 and the telescopic rod 27 are conventional electrically controlled push rods in the prior art.

[0039] Please see Figure 1 - Figure 3 A solenoid valve assembly 29 is fixedly installed on the inner side of the vertical frame 26. The solenoid valve assembly 29 is a conventional solenoid valve assembly 29 in the prior art. A pump body 30 is fixedly installed on the top surface of the vertical frame 26. A placement box 31 is fixedly installed on the inner side of the vertical frame 26. The placement box 31 is located above the solenoid valve assembly 29. The inlet of the pump body 30 is connected to the placement box 31 through a hose. The pump body 30 is a conventional pressure pump in the prior art. The outlet of the pump body 30 is connected to the solenoid valve assembly 29 through a pipeline. Multiple outlets of the solenoid valve assembly 29 are connected to multiple inlet pipes 21 through hoses.

[0040] Two spraying racks 1 are symmetrically fixedly mounted with a fixed frame 32 on their bottom surfaces. Multiple recovery ports 33 are fixedly mounted on the surface of the fixed frame 32. A manifold 34 is fixedly mounted in the middle of the bottom surface of the fixed frame 32. Multiple return pipes 35 connected to the circuit are fixedly mounted on both sides of the spraying equipment 3. The return pipes 35 are connected to the recovery ports 33 through hoses. A recovery bucket 36 is placed on the surface of the base 25. The manifold 34 is connected to the recovery bucket 36 through hoses. When the sprayer 5 coats the coating position of the injection molded part body 11, excess resist plating oil reaches the recovery port 33 through multiple return pipes 35 and hoses. The resist plating oil is then collected through the manifold 34. Finally, the collected resist plating liquid is collected in the recovery bucket 36. This prevents excess resist plating liquid from leaking out and also recycles the resist plating liquid, saving the use of resist plating liquid resources.

[0041] A controller 37 is fixedly mounted on the surface of the vertical frame 26. The controller 37 is a conventional programmable control device in the prior art, and the electrical equipment controlled by the controller 37 is also prior art, which will not be described in detail here. The controller 37 is electrically connected to the motor 17, the telescopic device 19, the motor 24, the pump body 30, and the telescopic rod 1 27 and the telescopic rod 28.

[0042] The steps of using this invention are as follows: Before the spraying equipment 3 starts operating, the operator inputs the coating point data of the injection molded part body 11 to be processed through the operation controller 37, calculates the distance data from the sprayer 5 to the coating point, and the controller 37 automatically stores the data as a processing program. The injection molded part body 11 is fixedly placed on the surface of the lifting rod 18. Using existing external lifting equipment, the lifting rod 18 and the injection molded part body 11 are moved through the placement groove 12 between the first rotating frame 7 and the second rotating frame 8. After the transfer is completed, the motor 17 rotates counterclockwise, causing the first gear 14 to rotate counterclockwise. At the same time, the second gear 15 rotates clockwise, causing the first gear 14 to rotate counterclockwise. The second gear 15 rotates clockwise, causing the first rotating frame 7 to rotate counterclockwise. The rotating mechanism causes the rotating frame 2 8 to rotate clockwise. At this time, the rotating frames 1 7 and 2 8 rotate in opposite directions, causing multiple vision acquisition devices 9 to scan and collect the coating position of the injection molded part body 11. After the rotating frames 1 7 and 2 8 rotate 180 degrees, the multiple vision acquisition devices 9 transmit the collected coating position data of the injection molded part body 11 to the controller 37. The controller 37 first controls the telescopic rod 1 27 and telescopic rod 2 28 to extend simultaneously. The extension of the telescopic rod 1 27 and telescopic rod 2 28 respectively causes the two slides 2 to move towards each other. The two slides 2 moving towards each other cause the two cross frames 13 to move towards each other. The two cross frames 13 moving towards each other cause the two spraying devices 3 to move towards the injection molded part body 11. At this time, multiple retractable sprayers 5 follow the spraying devices 3. After the two spraying devices 3 have completed their movements, the distance between the multiple retractable sprayers 5 and the injection molded part body 11 is initially adjusted, determining the distance between the sprayers 5 and the coating positions on the injection molded part body 11. The coating position data of the injection molded part body 11 collected by multiple vision acquisition devices 9 is compared with the coating point data and the distance data between the sprayers 5 and the coating positions on the injection molded part body 11 entered by the operator into the controller 37. This comparison then controls all the telescopic devices 19 corresponding to the spraying points. The telescopic devices 19 extend, moving the connecting disc 20. The movement of the connecting disc 20 moves the retractable sprayers 5 towards the coating points on the surface of the injection molded part body 11. Because the surface of the injection molded part body 11 is uneven, and the distance between the coating points on the injection molded part body 11 and the sprayers 5... Depending on the distance, the retractable sprayer 5 is extended and retracted according to the coating points on the injection molded part body 11, ensuring that the distance between the nozzle positions of all sprayers 5 and all coating positions on the injection molded part body 11 is the same. After adjustment, the controller 37 controls the pump body 30 to operate, drawing the resist plating liquid from the placement box 31 and delivering it to the solenoid valve assembly 29. Based on the sprayer 5 to which the resist plating liquid is to be sprayed, the controller controls the outlet of the solenoid valve assembly 29 connected to the sprayer 5 to open. At this time, the resist plating liquid is delivered through the hose to the inlet pipe 21 and sprayed out through the corresponding sprayer 5, coating the desired positions on the injection molded part body 11. The coated injection molded part body 11 is then transported to the next processing step.This scheme uses rotating frames 7 and 8 in opposite directions to scan and collect the coating position of the injection molded part body 11 using multiple vision acquisition devices 9. The coating position data collected by the multiple vision acquisition devices 9 is compared with the coating point data and the distance data between the sprayer 5 and the coating position of the injection molded part body 11 entered by the operator into the controller 37. Telescopic rods 27 and 28 extend, respectively carrying two spraying devices 3 towards the injection molded part body 11. At this time, multiple retractable sprayers 5 follow the spraying devices 3. After the initial adjustment of the distance between the multiple retractable sprayers 5 and the injection molded part body 11, the distance between the sprayer 5 and the coating position of the injection molded part body 11 is obtained. Because the surface of the injection molded part body 11 is uneven, and the coating point of the injection molded part body 11 is close to the sprayer 5, the distance between the sprayer 5 and the coating position of the injection molded part body 11 is determined. The distance between the sprayers 5 and the coating points on the injection molded part 11 varies. The retractable sprayers 5 are controlled to extend and retract, ensuring that the distance between the nozzles of all sprayers 5 and the coating points on all injection molded parts 11 is the same. Compared to traditional coating devices, this spraying equipment 3 uses retractable sprayers 5, making the distance between multiple sprayers 5 and multiple coating points on the injection molded part 11 the same. Under the same pump pressure, the sprayers 5 can complete the coating of the injection molded part 11. This not only solves the problems of blurred coating edges, inaccurate positioning, incomplete spraying, and missed spraying when the distance between the spray needle and the spray point is too large, but also solves the problem of splashing of the coating agent upon contact with the surface of the injection molded part 11 when the distance between the spray needle and the spray point is too small, thus improving the coating quality of the injection molded part 11.

[0043] During the coating process of the sprayer 5 on the coating position of the injection molded part body 11, the excess resist plating oil reaches the recycling port 33 through multiple return pipes 35 and hoses. The resist plating oil is then collected through the manifold 34, and finally the collected resist plating liquid is collected into the recycling tank 36. This prevents the excess resist plating liquid from leaking out and also recycles the resist plating liquid, saving the use of resist plating liquid resources.

[0044] The motor 24 rotates, causing the lead screw 23 to rotate. The rotation of the lead screw 23 causes the spraying equipment 3 to move inside the cross frame 13. When both sides of the injection molded part body 11 need to be sprayed, after the two spraying equipment 3 have finished moving, their positions correspond to each other. Without flipping the injection molded part body 11, both sides of the injection molded part body 11 can be coated simultaneously. When the positions of the two spraying equipment 3 are misaligned, multiple injection molded parts body 11 can be coated on one side, further improving the coating efficiency of the injection molded part body 11.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
