Description

Technical Field

[0001] The present invention relates to the technical field of spraying devices, and more particularly to an automatic spraying device for metal stamping parts. Background Art

[0002] Spraying is a coating method in which the spray gun or disc atomizer is used to disperse the spray into uniform and fine droplets with the help of pressure or centrifugal force, and then the droplets are applied to the surface of the object to be coated. When spraying the workpiece with existing spray equipment, the staff hangs the parts on a hook and transports them to the spraying area through a conveyor chain. The staff then uses a handheld spray gun to spray the parts. In this process, the parts are only hung by one hook, which makes them prone to shaking during transportation. In addition, when the staff uses the spray gun to spray, the back of the parts cannot be sprayed, and the staff needs to manually adjust the angle of the parts by manually adjusting the angle. In addition, the parts are affected by the impact of the spray gun and will also shake during spraying, which not only causes waste of spray materials but also increases the spraying time.

[0009] The present invention is further configured as follows: the reset components are divided into multiple groups, and the multiple groups of reset components are arranged corresponding to the multiple through holes. The multiple groups of reset components all include a cover plate, which is sleeved on the outer wall of the pull rod and installed on the top of the tube body. A piston is installed on the outer wall of the pull rod and below the cover plate. A torsion spring is connected between the top of the piston and the bottom of the cover plate. A threaded groove is provided on the inner wall of the tube body, and a boss is installed on the outer wall of the piston. The boss is slidably connected to the inside of the threaded groove.

[0010] The present invention is further configured as follows: a sealing sleeve is provided at the connection between the cover plate and the pull rod; two tapered holes are symmetrically provided on the top of the cover plate; and the tapered holes are tapered from top to bottom.

[0011] The present invention is further configured as follows: the protective component includes a protective cover, which is sleeved on the outside of the bracket and slidably connected to the top of the base, the front surface of the protective cover is hingedly mounted with a door body, and the front surface of the door body is mounted with a handle.

[0013] The present invention is further configured as follows: two electric slide rails are vertically installed inside the protective cover, and the two electric slide rails are respectively arranged corresponding to two groups of spraying components. The electric slide rails are located at the connection between the supporting platform and the protective cover, and the supporting platform is slidably connected to one side of the electric slide rails.

[0014] The advantages of the present invention are:

[0015] (1) By setting up a hanging component and a pulling component, the six-axis manipulator takes out the metal stamping part and hangs it on the second hanging rod, and presses down or lifts up the second hanging rod according to the length of the metal stamping part so that the hole on the metal stamping part is fitted onto the first hanging rod.

[0016] (2) By setting up two groups of spraying components, the two groups of spraying components move up and down on the front and back sides of the metal stamping part respectively, so that the front and back sides of the metal stamping part can be sprayed. When the spraying components move down, they can drive the pull rod and the piston to move down. The piston drives the boss to slide inside the thread groove. The piston rotates during the downward movement and drives the pull rod, the Y-shaped frame and the second hanging rod to rotate synchronously. The second hanging rod drives the metal stamping part and the first hanging rod to rotate. At this point, the metal stamping part rotates for the first time during the spraying process, thereby ensuring the uniformity of the spraying and eliminating the need for manual operation by the staff.

[0017] (3) The piston divides the inner cavity of the tube into an upper cavity and a lower cavity. When the piston moves downward, air is sucked into the upper cavity through the large diameter of the tapered hole. When the support platform moves upward, the torsion and elastic force of the torsion spring drive the piston and the pull rod to rotate and move upward to reset. Since the bottom end of the tapered hole has a smaller aperture, the air is discharged slowly. The piston moves upward slowly under the influence of air pressure, thereby slowing down the upward movement of the pull rod, Y-shaped frame and the second hanging rod. The second rotation speed of the metal stamping part slows down, which can increase the time that the side of the metal stamping part faces the muzzle of the spray gun, thereby achieving the purpose of uniform spraying.

[0032] Example

[0033] See also Figure 1-10 , the present invention provides the following technical solutions:

[0034] An automatic spraying device for metal stamping parts includes a base 1, a placing component 2 is installed on the top of the base 1, and a hanging component 3 is installed on the top of the placing component 2. The placing component 2 is used to support the hanging component 3, so that there is a large gap between the hanging component 3 and the base 1, and the metal stamping part that needs to be sprayed can be suspended in this gap through the hanging component 3. A pulling component 5 is installed inside the placing component 2 and directly below the hanging component 3. A reset component 4 is installed inside the pulling component 5. When the metal stamping part is suspended by the hanging component 3, the pulling component 5 applies a downward pulling force to the metal stamping part, thereby ensuring that the metal stamping part does not shake when suspended. When the pulling component 5 applies the downward pulling force to the metal stamping part, the reset component 4 It can slow down the speed at which the pulling force disappears, causing the metal stamping parts to be pulled for a longer time, and through the cooperation of the reset component 4 and the pulling component 5, the metal stamping parts can rotate during the application of the pulling force and the gradual disappearance of the pulling force, thereby adjusting the angle of the metal stamping parts. The top of the base 1 is slidably connected with a protective component 6, which is sleeved on the outside of the placement component 2. Two groups of spray components 7 are installed inside the protective component 6, and one side of the placement component 2 extends between the two groups of spray components 7. The protective component 6 is used to drive the spray component 7 to move, and the spray component 7 is used to spray the metal stamping parts. This method not only reduces paint splashing, but also the protective component 6 can cover the metal stamping parts being sprayed. The entire device is automatically controlled by the control system.

[0035] The placement component 2 includes a bracket 21, which is installed in the middle of the top surface of the base 1. A support tube 22 is provided on the top of the bracket 21. Both ends of the support tube 22 are threadedly connected with screws 23. The end of the screw 23 away from the support tube 22 passes through the inner wall of the bracket 21. The suspension component 3 is connected to the support tube 22, and the connection between the screw 23 and the bracket 21 is locked by a locking nut to ensure that the screw 23 and the support tube 22 are axially stationary. The support tube 22 is connected to the bracket 21 by the screw 23. This method can facilitate the disassembly and assembly of the support tube 22. The support tube 22 is used to support the suspension component 3.

[0036] There are multiple groups of suspension components 3, and each group of suspension components 3 includes a clamp 31. The clamp 31 is clamped on the outer wall of the support tube 22. The outer wall of the clamp 31 is symmetrically connected to two support rods 32. The bottom of the two support rods 32 is fixedly connected to a fixing plate 33. One side of the fixing plate 33 is evenly provided with through grooves 34. A hook 35 is passed through the inside of a through groove 34. The bottom of the hook 35 is rotatably connected to a first hanging rod 36. The clamp 31 is used to fix the support rod 32 to the outer wall of the support tube 22. The hook 35 and the first hanging rod 36 are used together to hang metal stamping parts. Since the support rod 32 is tilted upward, when hanging metal stamping parts, the hook 35 can be hung inside a suitable through groove 34 according to the size of the metal stamping parts.

[0037] The pulling assembly 5 includes a support plate 51, which is located inside the bracket 21, and the two ends of the support plate 51 are detachably connected to the inner wall of the bracket 21. Through holes 56 are evenly opened on the top of the support plate 51. Multiple through holes 56 are corresponding to multiple groups of suspension components 3. A tube body 52 is passed through the inside of the through hole 56, and a pull rod 53 is passed through the inside of the tube body 52. ​​A Y-shaped frame 54 is installed on the top of the pull rod 53. The top of the Y-shaped frame 54 is connected to two second hanging rods 55. The two second hanging rods 55 are respectively connected to two first hanging rods in a group of suspension components 3. A hanging rod 36 is correspondingly set, and the pull rod 53 and the Y-shaped frame 54 cooperate to support the second hanging rod 55, and the tube body 52 limits the pull rod 53 in the vertical reverse direction, so that the pull rod 53 remains in a vertical state. When the first hanging rod 36 hangs the metal stamping part, the top of the second hanging rod 55 is also hung on the metal stamping part. When the pull rod 53, the Y-shaped frame 54 and the second hanging rod 55 move downward, the first hanging rod 36 and the second hanging rod 55 respectively apply up and down pulling force to a metal stamping part. This method can ensure that the metal stamping part will not swing.

[0038] The reset assembly 4 is a plurality of groups, and the plurality of reset assemblies 4 are arranged corresponding to the plurality of through holes 56. The plurality of reset assemblies 4 include a cover plate 41, which is sleeved on the outer wall of the pull rod 53 and installed on the top of the tube body 52. ​​The outer wall of the pull rod 53 and located below the cover plate 41 are provided with a piston 44. A torsion spring 46 is connected between the top of the piston 44 and the bottom of the cover plate 41. The inner wall of the tube body 52 is provided with a threaded groove 47. The outer wall of the piston 44 is provided with a boss 45. The boss 45 slides It is dynamically connected to the inside of the thread groove 47. When the pull rod 53 moves downward, it drives the piston 44 to slide inside the tube body 52, and the torsion spring 46 is pulled. As the piston 44 continues to move downward, the piston 44 drives the boss 45 to slide inside the thread groove 47. The piston 44 rotates during the downward movement, causing the torsion spring 46 to be twisted and generate torque during the process of being stretched. Conversely, when the pull rod 53 moves upward, the piston 44 is affected by the pull rod 53, the torsion spring 46 and the thread groove 47 to rotate upward and reset.

[0039] A sealing sleeve 42 is provided at the connection between the cover plate 41 and the pull rod 53. Two conical holes 43 are symmetrically opened on the top of the cover plate 41. The conical holes 43 are conically arranged from top to bottom. The piston 44 divides the inner cavity of the tube body 52 into an upper cavity and a lower cavity. When the piston 44 continues to move downward, the space of the upper cavity increases, and negative pressure is generated inside it, causing external air to flow into the interior of the tube body 52 through the large diameter of the conical hole 43 and accumulate in the upper cavity. Conversely, when the piston 44 moves upward, the space of the upper cavity shrinks and the air inside it is squeezed. Since the bottom end aperture of the conical hole 43 is small, the speed at which air enters the conical hole 43 is slow, that is, the air is discharged slowly, thereby slowing down the upward movement speed of the piston 44, the pull rod 53, the Y-shaped frame 54 and the second hanging rod 55.

[0040] The protective component 6 includes a protective cover 61, which is mounted on the outside of the bracket 21 and is slidably connected to the top of the base 1. A door body 62 is hingedly installed on the front surface of the protective cover 61, and a handle 63 is installed on the front surface of the door body 62. The protective cover 61 slides left and right on the top of the base 1, and the length of the protective cover 61 is less than the length of the bracket 21. Therefore, the protective cover 61 can only block part of the suspension component 3, and the other part of the suspension component 3 is exposed. This part of the suspension component 3 is convenient for loading. When the device needs to be repaired, the staff can open the door body 62 through the handle 63 to repair the spray component 7 in the protective cover 61.

[0041] The two groups of spraying components 7 each include a carrying platform 71, and the two carrying platforms 71 are respectively located at the front and rear sides of the bracket 21. Spray guns 72 are evenly installed on the top of the two carrying platforms 71. The discharge port of the spray gun 72 points to the position where the component 2 is placed. The pull rod 53 is set in an L shape, and the pull rod 53 is divided into a vertical part and a horizontal part. The side of the carrying platform 71 away from the protective cover 61 extends to the top of the horizontal part. Two electric slide rails 8 are vertically installed inside the protective cover 61. The two electric slide rails 8 are respectively set corresponding to the two groups of spraying components 7. The rail 8 is located at the connection between the supporting platform 71 and the protective cover 61, and the supporting platform 71 is slidably connected to one side of the electric slide rail 8. The spraying assembly 7 is displaced synchronously with the movement of the protective cover 61, that is, the spray gun 72 sprays the metal stamping parts in the protective cover 61. The electric slide rail 8 is used to adjust the height of the two groups of spraying assemblies 7, so that uniform spraying can be performed from both sides of the metal stamping parts. When the spraying assembly 7 moves downward, the supporting platform 71 pushes the pull rod 53 in the protective cover 61 downward, which can trigger the operation of the pulling assembly 5 and the reset assembly 4.

[0042] Specifically, an external six-axis manipulator group is provided on one side of the base 1, and the external six-axis manipulator group can slide left and right on one side of the base 1, and its sliding position is misaligned with the sliding position of the protective component 6. The control system controls the six-axis manipulator to take out the metal stamping part and hang it on the second hanging rod 55, and presses down or lifts up the second hanging rod 55 according to the length of the metal stamping part, so that the hole on the metal stamping part is fitted onto the first hanging rod 36, and the placement of the metal stamping part is completed. This method can ensure that the metal stamping part will not swing, and all the suspension components 3 and pulling components 5 exposed outside the protective cover 61 are placed in this way;

[0043] After all the hanging components 3 and pulling components 5 exposed outside the protective cover 61 have completed the placement of the metal stamping parts, the control system controls the protective cover 61 to slide on the top of the base 1 so that it covers the metal stamping parts that have been hung.

[0044] At this time, the control system controls the displacement of the six-axis manipulator group. When the protective cover 61 moves to the position of the metal stamping part, the six-axis manipulator group moves to all the suspension components 3 and pulling components 5 exposed outside the protective cover 61, and the six-axis manipulator group continues to complete the placement action.

[0045] After the protective cover 61 covers the suspended metal stamping part, the control system controls the electric slide 8 and the spray gun 72 to start. The two groups of spray guns 72 spray the paint from the front and back sides to the front and back surfaces of the metal stamping part respectively. The electric slide 8 drives the two groups of spraying components 7 to make an up and down reciprocating motion as a whole, so that the spray guns 72 spray the front and back surfaces of the metal stamping part evenly.

[0046] When the supporting platform 71 moves down to the position of the pull rod 53, the pull rod 53 moves down under the influence of the thrust, and the pull rod 53 drives the Y-shaped frame 54 and the second hanging rod 55 to move down. When the second hanging rod 55 moves down, it pulls the metal stamping part down, and the first hanging rod 36 pulls the metal stamping part upward. At this point, the metal stamping part is subjected to the upper and lower pulling forces at the same time to ensure that it does not shake, thereby avoiding the situation where the metal stamping part shakes due to the impact of the paint;

[0047] During the downward movement of the pull rod 53, the piston 44 is driven to slide inside the tube 52, and the torsion spring 46 is pulled. As the piston 44 continues to move downward, the piston 44 drives the boss 45 to slide inside the thread groove 47. The piston 44 rotates during the downward movement, causing the torsion spring 46 to be twisted and generate torque during the process of being stretched. The piston 44 drives the pull rod 53, the Y-shaped frame 54 and the second hanging rod 55 to rotate synchronously. The second hanging rod 55 drives the metal stamping part and the first hanging rod 36 to rotate. At this point, the metal stamping part rotates during the spraying process, thereby ensuring the uniformity of the spraying and eliminating the need for manual operation by the staff.

[0048] The piston 44 divides the inner cavity of the tube body 52 into an upper cavity and a lower cavity. As the piston 44 continues to move downward, the space in the upper cavity increases, generating negative pressure inside the upper cavity. This causes external air to flow into the interior of the tube body 52 through the large diameter of the tapered hole 43 and accumulate in the upper cavity. When the support platform 71 moves upward, the thrust of the support platform 71 on the pull rod 53 disappears. At this time, the torsion and elastic force of the torsion spring 46 drive the piston 44 and the pull rod 53 to rotate and move upward to reset.

[0049] However, when the piston 44 moves upward, the space in the upper chamber shrinks and the air inside is squeezed out. Since the bottom end of the tapered hole 43 has a smaller diameter, the air enters the tapered hole 43 more slowly, that is, the air is discharged more slowly. As a result, the piston 44 moves upward more slowly due to the air pressure, thereby slowing down the upward movement of the pull rod 53, the Y-shaped frame 54, and the second hanging rod 55.

[0050] The purpose of this method is to slow down the speed of the second rotation of the metal stamping part. That is, during the first rotation, the metal stamping part is rotated by the thrust of the support platform 71 pushing the pull rod 53. The rotation speed is relatively fast, and uneven spraying may occur on the side of the metal stamping part during the spraying process. After the second rotation speed is slowed down, the time when the side of the metal stamping part faces the muzzle of the spray gun 72 can be increased, thereby achieving the purpose of uniform spraying.

[0051] When the metal stamping parts in the protective cover 61 are sprayed, the metal stamping parts exposed to the outside of the suspension component 3 and the pulling component 5 are placed. The control system controls the protective cover 61 and the six-axis manipulator group to run in an offset manner and switch positions. The six-axis manipulator disassembles and replaces the metal stamping parts after spraying, and the spraying operation continues in the protective cover 61.
