Description

Technical Field

[0001] This invention relates to the field of suspended painting molds, and more particularly to a suspended painting mold core processing device. Background Technology

[0002] Suspended mold coating, as the name suggests, involves the coating mold floating due to buoyancy, which promotes a more uniform paint film. The condition for mold levitation is as follows: In enameled wire production, the paint adhering to the wire is subjected to pressure within the mold due to the wire's movement speed and mold angle. When this pressure is sufficient to suspend the mold, and the wire is centered, this pressure provides the necessary buoyancy. The prerequisite for mold levitation is that the pressure must exceed the mold's own weight. Greater pressure results in greater buoyancy; for better levitation, the lighter the mold, the better.

[0003] The suspended painted mold core is made of 304 stainless steel, with the center painted part made of diamond material, which can be natural or artificial diamond. The painted mold core with diamond inlaid needs to undergo the final and most important step, which is to drill holes in the diamond core and then polish it. Currently, the polishing is done semi-automatically. After the mold is completed, the interior also needs to be polished. Due to the high precision requirements, the use of semi-automatic polishing results in a high defect rate. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a suspended painting mold core processing device.

[0005] To achieve the purpose of this invention, the technical solution adopted by this invention is: a suspended coating mold core processing device, comprising an anti-leakage adhesive application area, a polishing liquid injection area, and a diamond core drilling area;

[0006] Anti-leakage adhesive application area: This area is equipped with a mold core input conveyor belt, a rotary conveyor, and an anti-leakage adhesive application machine. The rotary conveyor has multiple mold core slots arranged in a circular array. The rotary conveyor is driven to rotate by a servo motor. Along the rotation direction of the rotary conveyor, there are sequentially arranged mold core input station, mold core adhesive application station, mold core transition station, and mold core output station. The end of the mold core input conveyor belt corresponds to the mold core slot at the mold core input station. An anti-leakage adhesive application machine is installed above the mold core slot at the mold core adhesive application station.

[0007] Polishing slurry filling area: includes a flipping gripper, a transfer conveyor belt, and a polishing slurry storage tank. A flipping gripper is provided on one side of the mold core slot at the mold core output station. The flipping gripper picks up the mold core on the mold core slot and flips it 180° to send the mold core with the adhesive side facing down onto the transfer conveyor belt. A polishing slurry storage tank is provided on one side of the transfer end of the transfer conveyor belt. An infusion tube is inserted into the polishing slurry storage tank. The outlet of the infusion tube extends to directly above the mold core at the transfer end of the transfer conveyor belt. An infusion pump is provided on the infusion tube.

[0008] Diamond core drilling area: includes transfer grippers, drilling table and ultrasonic drill bit. The transfer grippers pick up the mold core at the end of the transfer conveyor belt and send it into the drilling table. The drilling table is driven to rotate and drill through a drilling motor. An ultrasonic drill bit is set directly above the drilling table. The ultrasonic drill bit is driven to rotate downward through a sliding screw. A discharge chute is set on one side of the drilling table.

[0009] The adhesive applicator includes an adhesive applicator bracket, an adhesive feeding roll, an adhesive receiving roll, and an adhesive applicator cylinder. Adhesive tape limiting rollers are installed on both sides above the mold core slot at the adhesive applicator station. An adjusting roller is installed on each of the two adhesive tape limiting rollers facing each other. An adhesive feeding roll and an adhesive receiving roll are installed on the outer sides of each of the two adjusting rollers facing each other. The adhesive tape passes sequentially from the adhesive feeding roll through the adjusting roller, the adhesive tape limiting roller, the adhesive tape limiting roller, and the adjusting roller before returning to the adhesive receiving roll, which is simultaneously driven by a servo motor. An adhesive applicator cylinder is installed above the two adhesive tape limiting rollers, and an adhesive applicator pressure block is installed at the end of the pneumatic rod below the adhesive applicator cylinder, with the pressure block facing the mold core slot.

[0010] The adhesive applicator support is equipped with an adhesive applicator pressing roller on the side of the transition station near the mold core. The adhesive applicator pressing roller is made of soft rubber. The rotating shafts at both ends of the adhesive applicator pressing roller are set on deformable elastic metal sheets. Under normal conditions, the lowest point of the adhesive applicator pressing roller is lower than the highest point of the mold core.

[0011] The adjusting roller has a telescopic rod connected to the shafts at both ends. The telescopic rod is vertically arranged and extends into the spring sleeve from the top. A piston block is provided at the end of the telescopic rod that extends into the sleeve, and a spring is provided between the piston block and the bottom of the spring sleeve.

[0012] Positioning baffles are provided at the transmission ends and on both sides of the mold core input conveyor belt and the transfer conveyor belt; the mold core input conveyor belt has an opening on the side near the mold core input station and a pushing cylinder on the other side; the transfer conveyor belt has an opening on the side near the drilling table at its transmission end.

[0013] The flipping gripper includes a wide gripper cylinder, a clamping plate, and a rotary cylinder; a clamping plate is provided on each side of the pneumatic rod of the wide gripper cylinder, and anti-slip rubber is provided on the facing sides of the two clamping plates; a connecting plate is provided on one side of the wide gripper cylinder, and the rotating shaft of the rotary cylinder passes through the connecting plate and is fixed thereto.

[0014] A discharge cylinder is provided below the transfer gripper to drive the transfer gripper up and down, and the bottom of the discharge cylinder is provided on the module lead screw.

[0015] The drilling platform includes an upper rotating platform and a lower rotating platform. The upper rotating platform has a cavity on its inner side and an opening at its bottom for the lower rotating platform to extend and retract. The inner wall of the drilling platform has a circular array of multiple vertical sliding grooves. The lower rotating platform has a slider at a corresponding position. A spring is installed between the top of the cavity of the drilling platform and the top of the lower rotating platform. A magnet is installed in the middle of the top of the rotating platform. The lower rotating platform has circular teeth on its lower side. A toothed belt is fitted around the circular teeth and is driven to rotate by a drilling motor.

[0016] The beneficial effects of this invention are as follows:

[0017] Applying adhesive serves two purposes: firstly, it increases the friction between the mold core and the drilling table; secondly, since drilling and polishing are performed simultaneously in this device, after adding polishing fluid and drilling the diamond, the fluid will flow out, resulting in poor polishing. At the same time, the fluid flowing onto the polishing table requires frequent cleaning of the entire processing equipment. Therefore, applying adhesive perfectly solves the problem of these two processes not being able to be performed simultaneously. It allows for polishing of the mold core while drilling, and also prevents fluid from flowing out. A small amount of polishing fluid is sufficient to complete the polishing process.

[0018] The upper rotating platform and the lower rotating platform are separated. A magnet is set on the top of the lower rotating platform. When drilling is required, the magnet adheres to and attracts the mold core, and the friction of the adhesive paper causes it to rotate. When drilling and grinding are finished and the magnetism is no longer needed, the rotating platform and the lower rotating platform are separated by the action of springs. This way, the gripper does not have magnetic force, making gripping simple. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0031] See Figure 1-10 .

[0032] This invention discloses a suspended painting mold core processing device (see Figure 1 , 2 ), including the anti-leakage adhesive area 1, the polishing fluid filling area 2, and the diamond core drilling area 3;

[0033] Anti-leakage adhesive application area 1: This area is equipped with a mold core input conveyor belt 11, a rotary conveyor 12, and an anti-leakage adhesive application machine 13. The rotary conveyor 12 has multiple mold core slots 121 arranged in a circular array. The turntable is driven to rotate by a servo motor. Along the rotation direction of the turntable, there are sequentially arranged mold core input station 122, mold core adhesive application station 123, mold core transition station 124, and mold core output station 125. The end of the mold core input conveyor belt 11 corresponds to the mold core. The mold core slot 121 at the input station is equipped with a glue-proofing machine 13 above the mold core slot 121 at the mold core gluing station 123. The suspended painted mold cores are placed on the mold core input conveyor belt 11 with the side to be glued facing up for input. At the end of the mold core input conveyor belt 11, they are fed into the mold core slot 121 of the rotary conveyor plate 12 for step-by-step rotary conveying. When passing through the mold core gluing station 123, they are glued by the glue-proofing machine 13.

[0034] Polishing slurry filling area 2 includes a flipping gripper 21, a transfer conveyor belt 22, and a polishing slurry storage tank 23. A flipping gripper 21 is provided on one side of the mold core slot at the mold core output station. The flipping gripper picks up the mold core from the mold core slot and flips it 180°, turning the mold core with the adhesive side facing down and sending it onto the transfer conveyor belt 22. A polishing slurry storage tank 23 is provided on one side of the transfer end of the transfer conveyor belt 22. An infusion tube 231 is inserted into the polishing slurry storage tank 23, and the outlet of the infusion tube 231 extends to the transfer conveyor belt 23. 2. Above the mold core at the end of the transmission line, an infusion pump is installed on the infusion tube. After the mold core is glued in the anti-leakage adhesive area 1, it is transferred to the mold core output station 125. The flipping gripper 21 picks up the mold core at the mold core output station 125 and flips it 180°, sending it onto the transfer conveyor belt 22. The infusion tube 231 is installed above the end of the transfer conveyor belt 22. The infusion tube 231 drips polishing liquid. The polishing liquid is a mixture of diamond powder and water. A little pigment is added to the polishing liquid so that the staff can tell at a glance whether polishing liquid has been dripped in.

[0035] Diamond core drilling area 3 includes a transfer gripper 31, a drilling table 32, and an ultrasonic drill bit 33. The transfer gripper 31 picks up the mold core from the end of the transfer conveyor belt and feeds it into the drilling table. The drilling table is driven to rotate and drill by a drilling motor 326. An ultrasonic drill bit is positioned directly above the drilling table and rotates downwards via a sliding screw. A discharge trough 34 is provided on one side of the drilling table. Mold cores awaiting polishing fluid addition at the end of the transfer conveyor belt 22 in polishing fluid filling area 2 are picked up by the transfer gripper 31. The two gripper arms of the transfer gripper can open outwards by 90° to pick up the cores and feed them into the drilling table for drilling and polishing. Finally, the cores are fed out into the discharge trough 34.

[0036] like Figure 3 , 4As shown in Figure 5, the anti-leakage adhesive applicator 13 includes an adhesive applicator bracket 131, an adhesive feeding roll 132, an adhesive receiving roll 133, and an adhesive applicator cylinder 134. Adhesive tape limiting rollers 135 are arranged on both sides above the mold core slot at the adhesive applicator station. An adjusting roller 136 is arranged on each of the two adhesive tape limiting rollers facing each other. An adhesive feeding roll and an adhesive receiving roll are arranged on the outer sides of each of the two adjusting rollers facing each other. The adhesive tape passes sequentially through the adjusting roller, the adhesive tape limiting roller, the adhesive tape limiting roller, and the adjusting roller from the adhesive feeding roll and is then returned to the adhesive receiving roll. The adhesive receiving roll is simultaneously driven by a servo motor 137. An adhesive applicator cylinder 134 is arranged above the two adhesive tape limiting rollers. An adhesive applicator pressure block 138 is arranged at the end of the pneumatic rod below the adhesive applicator cylinder, and the pressure block faces the mold core slot. The adjusting roller 136 has a telescopic rod 1361 connected to the rotating shafts at both ends. The telescopic rod is vertically positioned and extends into the spring sleeve 1362. A piston block 1363 is provided at the extended end of the telescopic rod, and a spring 1364 is provided between the piston block and the bottom of the spring sleeve. Since the adhesive is applied by pressing the adhesive tape with a cylinder, the tape may be pulled. If the tape is too rigid, it is easy to break or difficult to recover, resulting in loose tape that is difficult to apply later. The adjusting roller 136, under the influence of the spring and its own weight, positions the piston block 1363 in the middle of the spring sleeve. When the adhesive tape is pressed down, the adjusting roller 136 also moves to match the rapidly moving tape. After application, the adhesive cylinder 134 retracts, breaking the force balance between the spring and the telescopic rod, and the adjusting roller 136 returns to its original position, flattening the tape for the next application.

[0037] like Figure 3 As shown, an adhesive applicator roller 14 is provided on the side of the adhesive applicator bracket near the transition station of the mold core. The adhesive applicator roller is made of soft rubber, and the pivots at both ends of the adhesive applicator roller are mounted on deformable elastic metal sheets 141. Under normal conditions, the lowest point of the adhesive applicator roller is lower than the highest point of the mold core. Because insufficient adhesion may occur during the pressing and applying of adhesive, an adhesive applicator roller 14 with a bottom height lower than the mold core is provided to press and adhere the adhesive firmly along its movement trajectory.

[0038] like Figure 6 , 7 As shown, positioning baffles 4 are provided at the transmission ends and on both sides of the mold core input conveyor belt and the transfer conveyor belt; the mold core input conveyor belt has an opening 41 on the side near the mold core input station and a pushing cylinder 15 on the other side; the transfer conveyor belt has an opening 41 on the side near the drilling table at the transmission end.

[0039] like Figure 6The flipping gripper 21 shown includes a wide gripper cylinder 211, a clamping plate 212, and a rotary cylinder 213; a clamping plate 212 is respectively provided on the air pressure rods on both sides of the wide gripper cylinder 211, and anti-slip rubber is provided on the facing sides of the two clamping plates; a connecting plate 214 is provided on one side of the wide gripper cylinder 211, and the rotating shaft of the rotary cylinder passes through the connecting plate and is fixed thereto.

[0040] like Figure 8 The transfer gripper shown is equipped with a discharge cylinder 311 below it, which drives the transfer gripper to move up and down. The bottom of the discharge cylinder is mounted on the module lead screw. The grinding part above the drilling table 32 is a funnel-shaped groove, so the transfer gripper needs to be lowered. Therefore, the discharge cylinder 311 is set to drive it to lower the mold core for processing.

[0041] like Figure 9 , 10 The drilling platform 32 shown includes an upper rotating platform 321 and a lower rotating platform 322. The upper rotating platform has a cavity on its inner side and an opening at its bottom for the lower rotating platform to extend and retract. The inner wall of the drilling platform has a circular array of multiple vertical sliding grooves 3211. The lower rotating platform has a slider 3222 at a corresponding position. A spring 323 is provided between the top of the cavity of the drilling platform and the top of the lower rotating platform. A magnet 324 is provided in the middle of the top of the rotating platform. The lower rotating platform has circular teeth on its lower side. A toothed belt 325 is fitted onto the circular teeth and is driven to rotate by a drilling motor 326. However, the friction of the adhesive tape alone is not enough to achieve complete rotation with the rotating platform 322. Therefore, an upper rotating platform 321 and a lower rotating platform 322 are set up. The top of the lower rotating platform 322 is equipped with a magnet. The upper rotating platform 321 and the lower rotating platform 322 are made of non-magnetic metal. The attraction force between the magnet and the mold core is less than the elastic force of the spring. As long as the ultrasonic drill bit 33 presses down on the upper rotating platform 321 to make the magnet stick together, the magnet attracts the mold core and rotates the hole under the drive of the rotating cylinder. At the same time, the ultrasonic drill bit 33 and the polishing fluid polish it.
