[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present application, the driving motor is started to drive one of the driving shafts to rotate, so that the first gear on the driving shaft body rotates, and the meshing between the first gear and the driven teeth is used to make one side of the transmission chain rotate in the forward direction. In the above process, the rotation of the driving shaft will drive the second gear to rotate accordingly, and the two second gears are meshed and transmitted, so that the transmission chain on the other side rotates in the opposite direction, so that the parts will move in the forward and reverse directions when they are in the middle, and the parts will first pass through the first guard plate and the third guard plate, and then the second guard plate and the third guard plate will be moved under the above transmission, so as to realize spraying on both sides of the parts and use the same curing lamp to dry both sides of the material, which not only improves the spraying efficiency, but also ensures the effect after spraying.

[0028] 2. The limit cover can push the movable piston to compress and seal the ventilation pipe, so that when the ventilation pipe passes through the exhaust hole or the intake hole, the movable piston is automatically opened under the action of the support spring to realize gas exchange;

[0029] A micro vacuum pump is installed inside the exhaust hole, so that the air inside the ventilation pipe will be evacuated to a vacuum state when the ventilation pipe passes through, so that the vacuum suction cup will absorb the current parts, and when the ventilation pipe passes through the air intake hole, the outside air will be introduced into the conveying pipe, and the vacuum suction cup will be released from the vacuum state, so as to realize automatic unloading of parts;

[0030] By starting the auxiliary push rod, the sealing push plate can be pushed so that it can close the moving piston in real time, ensuring that before the parts are transferred to the other side, the vacuum suction cup on the current side is in a vacuum state. Then the electric push rod is started so that the docking push plate can push the support frame to connect the parts with the vacuum suction cup on the other side. After the connection, the auxiliary push rod and the recovery electric push rod open the moving piston and reset the support frame.

[0031] The above structure enables the present application to perform stable transfer when transferring parts, avoiding the situation where the parts fall prematurely, wherein the electric push rod will retract after the vacuum suction cup on the other side fixes the parts, thereby releasing the connection between the vacuum suction cup on the current side and the parts.

[0032] 3. Through the position of the first guard plate, one side of the component can be sprayed in advance, and then enter the third guard plate to be processed by the curing lamp to ensure that the spraying effect of the previous side is not disturbed when the other side is sprayed. After that, the other side can be sprayed through the position of the second guard plate, and then enter the third guard plate again to process the other side to ensure the stability of the spraying effect when taking the material later.

[0033] 4. Use the holding spring to hold the sealing cover so that the sealing cover will be sealed and fit on the surface of the limit cover to ensure that during the vacuum pumping process, the current vacuum hole is in a sealed state and will not be disturbed by the outside air to avoid the decrease of the suction force of the vacuum suction cup. After the vacuuming is completed, the vacuum hole is inclined so that the inner wall of the vacuum hole will push the moving piston to move inside the ventilation pipe and seal it, thereby ensuring that the moving piston can be smoothly restricted by the limit cover in the future to ensure the current suction force of the vacuum suction cup.

[0055] In this embodiment, the base 1 has a driving shaft 104 rotatably mounted at both ends, a first gear 105 is fixedly mounted at the bottom of the driving shaft 104, and a driven tooth 301 is disposed on the inner wall of the transmission chain 3, and the driven tooth 301 meshes with the first gear 105;

[0056] A feeding platform 101 and a discharging platform 103 are respectively fixedly mounted on the outer surfaces of the base 1 on both sides;

[0057] A driving motor 106 is fixedly mounted on the upper end of one of the bases 1 , and an output end of the driving motor 106 is fixedly connected to one of the driving shafts 104 .

[0058] The two driving shafts 104 are fixedly mounted with second gears 202 , the outer side of the driving shafts 104 is provided with a protective chassis 2 , the interior of the protective chassis 2 is provided with a transmission slot 201 , and the two second gears 202 are both located inside the transmission slot 201 and mesh with each other.

[0059] In the present application, the driving motor 106 is started to drive one of the driving shafts 104 to rotate, so that the first gear 105 on the shaft body of the driving shaft 104 rotates, and the meshing between the first gear 105 and the driven tooth 301 is used to make the transmission chain 3 on one side rotate in the forward direction. In the above process, the rotation of the driving shaft 104 will drive the second gear 202 to rotate accordingly, and the two second gears 202 are meshed and transmitted, so that the transmission chain 3 on the other side rotates in the opposite direction, so that the parts will move in the forward and reverse directions when they are in the middle, and the parts will first pass through the first guard plate 501 and the third guard plate 504, and then the second guard plate 502 and the third guard plate 504 will be moved under the above transmission, so as to realize the spraying of both sides of the parts and use the same curing lamp 506 to dry both sides of the material, which not only improves the spraying efficiency but also ensures the effect after spraying.

[0060] It should be noted that the control component 4 includes a limit cover 401, which is fixedly mounted on the upper surface of the base 1, and an air intake hole 402 is opened near the limit cover 401 on one side, and another air intake hole 402 is opened near the discharge platform 103 on the limit cover 401 on the other side;

[0061] An electric push rod 403 is fixedly installed under each air inlet hole 402, and a docking push plate 4031 is fixedly installed at the output end of the electric push rod 403;

[0062] An auxiliary push rod 406 for temporarily maintaining a vacuum state is fixedly installed inside each air inlet hole 402 , and a sealing push plate 4061 is fixedly installed at the output end of the auxiliary push rod 406 .

[0063] A suction hole 404 is provided on one side of the limiting cover 401 near the other side of the limiting cover 401, and another suction hole 404 is provided on the other side of the limiting cover 401 near the feeding platform 101;

[0064] A plurality of air extraction holes 404 are provided inside the limiting covers 401 on both sides, and a micro vacuum pump 405 is fixedly installed inside each of the air extraction holes 404 .

[0065] In order to realize automatic adsorption and discharge of materials, the movable piston 7063 is limited by the limit cover 401 during its movement, so that the movable piston 7063 blocks the ventilation pipe 7062 and seals the ventilation pipe 7062. When the movable piston 7063 moves to the exhaust hole 404 or the intake hole 402, the movable piston 7063 is pushed outward with the support of the support spring 7064, thereby opening the ventilation pipe 7062 and allowing gas to enter and exit the ventilation pipe 7062.

[0066] In the present application, a micro vacuum pump 405 is installed inside the air extraction hole 404, so that when the air exchange tube 7062 passes through, the piston 7063 is moved out, and the air extraction hole 404 is sealed with the sealing cover 7066, so that the micro vacuum pump 405 can evacuate the air inside the air exchange tube 7062 to make it a vacuum state, so that the vacuum suction cup 7053 can absorb the current parts, and when the air exchange tube 7062 passes through the air intake hole 402, the sealing cover 7066 is smaller than the air intake hole 402, and when the piston 7063 is moved out, the outside air will be automatically introduced into the conveying tube 706, and the vacuum suction cup 7053 will be released from the vacuum state, so as to realize the automatic unloading of parts;

[0067] In order to allow the parts to smoothly enter the connecting assembly 7 on the other side, the sealing push plate 4061 can be pushed by starting the auxiliary push rod 406, so that it can close the movable piston 7063 in real time, ensuring that before the parts are transferred to the other side, the vacuum suction cup 7053 on the current side is in a vacuum state, and then the electric push rod 403 is started so that the docking push plate 4031 can push the support frame 703, and the parts are connected to the vacuum suction cup 7053 on the other side. After the connection, the auxiliary push rod 406 and the recovery electric push rod 403 are connected, and the movable piston 7063 is opened and the support frame 703 is reset.

[0068] The above structure enables the present application to perform stable transfer when transferring parts, avoiding the situation where the parts fall prematurely, wherein the electric push rod 403 will shrink after the vacuum suction cup 7053 on the other side fixes the parts, thereby releasing the connection between the vacuum suction cup 7053 on the current side and the parts.

[0069] In the specific configuration, the spray assembly 5 includes a third guard plate 504, which is fixedly mounted in the middle of the base 1, and a drying tank 505 is provided inside the third guard plate 504, and a curing lamp 506 is fixedly mounted inside the drying tank 505;

[0070] A second guard plate 502 is fixedly installed on one side of the third guard plate 504 , a first guard plate 501 is fixedly installed on the upper surface of the protective chassis 2 , and a plurality of processing spray guns 503 are fixedly installed inside the first guard plate 501 and the second guard plate 502 .

[0071] Through the position of the first guard plate 501, one side of the component can be sprayed in advance, and then enter the third guard plate 504 to be processed by the curing lamp 506 to ensure that the spraying effect of the previous side is not disturbed when the other side is sprayed. After that, the other side can be sprayed through the position of the second guard plate 502, and then enter the third guard plate 504 again to process the other side to ensure the stability of the spraying effect when taking materials later.

[0072] In the present application, a limit slot 601 is fixedly installed on the upper end of each mounting column 6 , and the interior of each limit slot 601 is connected to the middle of the coil spring 7012 .

[0073] It should be noted that the connecting assembly 7 includes a mounting sleeve 701, a movable slide rail 702 is fixedly mounted on the upper end of the mounting sleeve 701, a support frame 703 is slidably mounted inside the movable slide rail 702 through a return spring 7021, rotation grooves 704 are respectively provided on both sides of the support frame 703, rotation columns 7042 are rotatably mounted inside the rotation grooves 704 on both sides, threaded holes 7041 are provided through the rotation columns 7042 on both sides and the middle of the support frame 703, a threaded rod 705 is threadedly mounted inside each threaded hole 7041, and a vacuum suction cup 7053 is connected to one end of each threaded rod 705;

[0074] The mounting sleeve 701 has a combined rotating groove 7011 formed therein and is rotatably mounted on the upper end of the mounting column 6 . The inner wall of the combined rotating groove 7011 is connected to the outer side of the coil spring 7012 . A coil spring 7012 is installed between the combined rotating groove 7011 and the limiting slot 601 .

[0075] The above structure enables the present application to rotate within a certain range, so as to facilitate personnel to pre-store materials and subsequently retrieve materials, and reduce damage to the mounting column 6 due to position movement during the process.

[0076] Among them, a rotating connection seat 7052 is rotatably mounted on one end of each threaded rod 705, a vacuum suction cup 7053 is fixedly mounted on one end of the rotating connection seat 7052, and a conveying pipe 706 is fixedly connected to the outer side of the rotating connection seat 7052;

[0077] A knob 7051 is fixedly mounted on the outer side of the threaded rod 705;

[0078] By turning the knob 7051, the threaded rod 705 can be threadedly matched with the threaded hole 7041, so that the extended length of the threaded rod 705 can be adjusted to ensure that the vacuum suction cup 7053 can meet the size of the current parts, thereby improving the applicability of the present application.

[0079] An expansion platform 707 is fixedly installed on the rotating columns 7042 on both sides and in the middle of the support frame 703. A stabilizing spring 7072 for supporting the threaded rod 705 is installed inside the expansion platform 707. A pipe rack 7071 is fixedly installed on the outside of each expansion platform 707. Each pipe rack 7071 is fixedly connected to the corresponding conveying pipe 706 inside.

[0080] The stabilizing spring 7072 can make the support frame 703 automatically reset after the outward push is canceled, so as to facilitate subsequent use, and the position of the delivery pipe 706 can be limited by the pipe frame 7071.

[0081] In the present application, a branch pipe seat 7061 is fixedly installed at the bottom of a plurality of pipe racks 7071, and the bottoms of a plurality of delivery pipes 706 are connected to the branch pipe seat 7061. A ventilation pipe 7062 is fixedly installed on one side of the branch pipe seat 7061, and a movable piston 7063 is movably installed inside the ventilation pipe 7062. A support spring 7064 is installed between the movable piston 7063 and the inner side of the branch pipe seat 7061, and a holding spring 7065 is arranged on the outer side of the ventilation pipe 7062. A sealing cover 7066 is movably arranged on the body of the ventilation pipe 7062, and the sealing cover 7066 is fixedly connected to the holding spring 7065. The area of ​​the sealing cover 7066 is larger than the air extraction hole 404.

[0082] A force-bearing pressure plate 7031 is extended from one side of the support frame 703 , and the force-bearing pressure plate 7031 is limitedly matched with the docking push plate 4031 .

[0083] When in use, the force-bearing pressure plate 7031 can receive the thrust from the electric push rod 403, so that the support frame 703 can extend outward, so that it can dock with the connecting component 7 on the other side;

[0084] The piston 7063 is moved to seal the ventilation tube 7062 when it is restricted by the limit cover 401, and the micro vacuum pump 405 is used to keep the current vacuum cup 7053 fixed to the parts. The supporting spring 7064 can make the parts pop out of the moving piston 7063 when passing through the air inlet hole 402, and the vacuum of the vacuum cup 7053 can be automatically released to make it contact with the parts. During the vacuuming process, the sealing cover 7066 is pressed by the holding spring 7065, so that the sealing cover 7066 will be sealed and fitted on the surface of the limit cover 401 to ensure that during the vacuum pumping process, the current vacuum hole 404 is in a sealed state and will not be disturbed by the outside air. After the vacuuming is completed, the vacuum hole 404 is tilted so that the inner wall of the vacuum hole 404 will push the moving piston 7063 to move inside the ventilation tube 7062 and seal it, thereby ensuring that the moving piston 7063 can be successfully restricted by the limit cover 401 later to ensure the suction of the current vacuum suction cup 7053.

[0085] The working principle of the surface spraying treatment device for automobile parts processing:

[0086] When in use, firstly, the material is replenished on the feeding table 101. During replenishment, the micro vacuum pump 405 is installed inside the air extraction hole 404, so that the air inside the ventilation tube 7062 is evacuated to make it a vacuum state when passing through, and then the vacuum suction cup 7053 can adsorb the current parts. The vacuum suction cup 7053 can be evacuated multiple times by providing multiple air extraction holes 404, so as to avoid the problem of reduced suction force of the vacuum suction cup 7053 during the process of transferring parts. During the air extraction process, the holding spring 7065 is used in conjunction with the sealing cover 7066 to ensure that the vacuum suction cup 7053 will not be disturbed by external gas during each air extraction process under the air extraction of the micro vacuum pump 405, thereby ensuring the suction force of the vacuum suction cup 7053.

[0087] In this process, the driving motor 106 is started to drive one of the driving shafts 104 to rotate, so that the first gear 105 on the shaft of the driving shaft 104 rotates, and the meshing between the first gear 105 and the driven tooth 301 is used to make the transmission chain 3 on one side rotate in the positive direction. In the above process, the rotation of the driving shaft 104 will drive the second gear 202 to rotate accordingly, wherein the two second gears 202 are meshed and transmitted, thereby making the transmission chain 3 on the other side rotate in the opposite direction, so that the parts will move in the positive and negative directions when in the middle;

[0088] In the above-mentioned moving direction, the parts will first pass through the first guard plate 501 and the third guard plate 504, and then move the second guard plate 502 and the third guard plate 504 under the above-mentioned transmission to achieve spraying on both sides of the parts and use the same curing lamp 506 to dry both sides of the material;

[0089] When the parts are transferred to the other side, the sealing push plate 4061 can be pushed by starting the auxiliary push rod 406, so that it can close the moving piston 7063 in real time, ensuring that before the parts are transferred to the other side, the vacuum suction cup 7053 on the current side is in a vacuum state, and then the electric push rod 403 is started so that the docking push plate 4031 can push the support frame 703, and the parts are connected to the vacuum suction cup 7053 on the other side. After the connection, the auxiliary push rod 406 and the recovery electric push rod 403 are connected, and the moving piston 7063 is opened and the support frame 703 is reset;

[0090] Finally, the parts will be transferred to the unloading platform 103 for personnel to take out. When taking them out, the ventilation pipe 7062 will introduce the outside air into the conveying pipe 706 when passing through the air inlet hole 402, and the vacuum state of the vacuum suction cup 7053 will be released, thereby realizing automatic unloading of the parts.

[0091] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
