Description

Technical Field

[0001] The present invention relates to the technical field of automobile manufacturing, and particularly to a clamping device and working method for automobile door installation. Background Art

[0002] At present, with the booming development of the automobile manufacturing industry, the output of automobiles is increasing day by day, and consumers' requirements for automobile quality are becoming increasingly stringent. With the continuous progress of technology, some automated equipment has begun to be involved in the field of automobile door installation. However, the existing automated equipment generally has some significant defects.

[0003] In terms of clamping, the clamping structure design of most equipment is not reasonable enough and the stability is poor. At the same time, due to the different sizes, shapes and materials of automobile doors of different brands and models, the existing automated equipment can often only install doors of one or several specific specifications, and it is difficult to flexibly adapt to the diverse door requirements, which undoubtedly limits the versatility and application scope of the equipment.

[0004] In addition, before the installation of automobile doors, it is usually necessary to carry out cleaning and drying treatments to ensure the cleanliness of the door surface and avoid impurities affecting the installation quality. However, most of the existing automated installation equipment lacks cleaning and drying functions, which requires additional dedicated cleaning and drying links before the installation process. This not only increases the equipment investment and site occupation, but also prolongs the production cycle and raises the production cost.

[0005] Today, with the increasingly prominent problems of resources and the environment, the rational use of water resources and environmental protection are attracting more and more attention. During the automobile manufacturing process, a large amount of water resources are consumed for cleaning doors. The existing cleaning equipment has obvious deficiencies in the recycling of water resources. Most of the used water is directly discharged without effective treatment, which not only causes a great waste of water resources, but also may pollute the environment due to pollutants such as oil stains and impurities in the sewage, and does not conform to the concept of sustainable development. In summary, a highly efficient, intelligent and environmentally friendly door installation clamping device that can overcome the above-mentioned problems is proposed, which has important practical significance for promoting the development of the automobile manufacturing industry. Summary of the Invention

[0011] Furthermore, the adsorption device includes a vacuum pump fixedly installed on one side of the supporting plate. An adsorption air pipe is arranged at the air inlet end of the vacuum pump. A branch air pipe is fixedly installed at one end of the adsorption air pipe. Several adsorption pipes are evenly arranged on one side of the branch air pipe.

[0012] Further, the air circulation device includes an air circulation box fixedly installed above the moving plate.

An air passing motor is fixedly arranged above the coarse-hole air passing plate. Driving gears are staggeredly arranged at the output end of the air passing motor.

A scraping plate is fixedly arranged below the scraping connecting plates. The scraping plate is in contact with the bottom of the filter water tank.

[0013] Further, a working method of a clamping device for automobile door installation includes the following steps: S1: Arrange the car doors evenly at both ends of the device to prepare for subsequent adsorption operations.

[0014] S2: Use the control device to control the operation of the moving device. The moving motor in the moving device drives the moving threaded rod to rotate, so that the moving sliding plate threadedly adapted to the moving threaded rod moves along the active slide rail, thereby driving the moving plate and the rotating motor, the supporting device, the scraping devices on both sides and the dryer installed below to move towards both ends of the device. The supporting device simultaneously drives the adsorption device to move; When the adsorption device moves to one end of the device, the suction cup contacts one side of the car door. At this time, use the control device to control the operation of the vacuum pump. The vacuum pump extracts the air inside the suction cup through the adsorption air pipe, the branch air pipe and the adsorption pipe, and is in a vacuum state, so as to adsorb the car door.

[0015] S3: Use the control device to control the rotation of the rotating motor. The rotating motor drives the support plate to rotate, and then the supporting device drives the adsorbed car door to adjust the direction so that the car door faces the vehicle frame direction to meet the subsequent installation requirements.

[0016] S4: After the direction of the car door is adjusted, use the control device to control the operation of the water pump. The water pump extracts the water source in the filter water tank and discharges it to the distribution pipe through the circulating water pipe; The distribution pipe sprays the water source on the surface of the car door through the atomizing nozzles. At the same time, the distribution pipe is moved up and down through the slide rails at both ends to ensure that the surface of the car door can be comprehensively washed with water; Moreover, during the movement of the mobile device, the scraping connection plates below both ends of the moving plate move accordingly. The scraping connection plates drive the scraper below to move in the filter water tank, scraping and moving the water and dust generated in the filter water tank, so that the water moves to one end of the filter water tank and flows into the water storage tank. The filter plate in the water storage tank filters the dust in the water source for the recycling of water resources. Meanwhile, due to the rotation of the supporting device, after the rinsing is completed, the car door is in the middle position between the two dryers. The control device is used to control the operation of the dryers, and the dryers perform the drying work on the surface of the car door. During the drying process, since water mist is generated during drying, the control device is used to control the operation of the air passing motor. The air passing motor drives the transmission fan to rotate. The transmission fan sucks the gas around the lower car door and discharges the gas to the exhaust box through the air passing channel. When the gas passes through the exhaust box, the thick-hole air passing plate blocks the impurity dust, and the fine filter screen further isolates the gas. At the same time, the surface of the fine filter screen blocks the hot mist, causing water condensate beads to form here. The water condensate beads drop into the vertical collection box. The gas in the exhaust box is discharged to the circulating air pipe through the exhaust pipe. The circulating air pipe is discharged through the circulating nozzle, and the circulating nozzle faces the position of the car door. The discharged gas blows and removes dust from the car door and accelerates the drying of the car door.

[0017] S5: The mobile device moves to the installation area to be installed. The operator installs the car door on the vehicle frame. After the installation is completed, the control device is used to stop the operation of the vacuum pump, so that the adsorption device cancels the adsorption of the car door.

[0018] S6: The mobile device moves to one end. The control device is used to control the rotation of the rotation motor, driving the support plate to rotate, so that the device is in a state where it can adsorb a new car door again, and is ready to perform the adsorption operation on the new car door.

[0019] The beneficial effects of this technical solution are as follows: (1) The clamping device of the present invention integrates multiple functions such as adsorption, rotation, cleaning, and drying. Through automated control and precise mechanical structures, the manual intervention links are greatly reduced, the production efficiency of car door installation is significantly improved, and the labor intensity of workers is reduced.

[0020] (2) The water circulation device realizes the efficient recycling of water resources through the coordinated work of components such as the filter water tank, filter plate, and drainage tank, reducing the waste of water resources. The air circulation device recovers and processes the mist generated during the drying process, not only reducing environmental pollution, but also accelerating the drying process of the car door through circulating blowing, reducing energy consumption.

[0021] (3) Structures such as the electric lifting rod and adjusting rod in the supporting device, and the adjustable suction plate in the suction device can be flexibly adjusted according to different models and sizes of car doors, ensuring that the suction cups are closely attached to the door surface, achieving precise adaptation to a variety of car door models, and improving the versatility and applicability of the device.

[0025] The specific implementation process is as follows: Embodiment 1: Please refer to Figures 1-10 , a technical solution provided by the present invention: a clamping device for installing a car door, including a plurality of brackets 1. The brackets 1 serve as the basic support structure of the entire device. A water circulation device 2 is fixedly provided below the brackets 1, a moving device 3 is fixedly provided above the brackets 1, a rotating motor 4 is fixedly provided below the moving device 3, a supporting device 5 is fixedly provided below the rotating motor 4, an adsorption device 6 is fixedly provided on one side of the supporting device 5, dryers 7 are symmetrically provided on the side of the supporting device 5, an air circulation device 8 is fixedly provided above the moving device 3, scraping devices 10 are symmetrically provided at both ends of the moving device 3, and a car door 9 is provided on one side of the adsorption device 6; Among them, the mobile device 3 includes a driving slide rail 301 fixedly installed above the bracket 1 by bolts. The bolts are evenly distributed and tightened to a specified torque to ensure the firm installation of the slide rail. One end of the driving slide rail 301 is provided with a mobile motor 302 through a motor base. The motor base is connected to both the driving slide rail 301 and the mobile motor 302 by bolts. The output end of the mobile motor 302 is tightly connected to the mobile threaded rod 303 through a high-precision coupling. The coupling ensures the concentricity of the motor output shaft and the threaded rod, reducing vibration during operation. The surface of the mobile threaded rod 303 is adapted to the mobile slide plate 304 through threads, and the thread precision meets relevant standards to ensure the smoothness of movement. When the mobile motor 302 rotates, the mobile slide plate 304 can move along the driving slide rail 301. A mobile plate 305 is fixedly installed below the mobile slide plate 304 by welding. At the same time, driven slide rails 306 are symmetrically arranged at both ends of the bracket 1. Driven rods are installed in the driven slide rails 306, and driven plates are movably arranged on the surfaces of the driven rods. The lower part of the driven plate is fixedly connected to the mobile plate 305 by welding. When the mobile motor 302 rotates to drive the mobile threaded rod 303 to rotate, the mobile slide plate 304 moves along the driving slide rail 301 under the action of the threads. Due to the coordinated action of the driven slide rail 306 and the driving slide rail 301, the mobile plate 305 can move stably, thereby driving other components installed below it to move and realizing the precise positioning of the adsorption device 6; The water circulation device 2 includes a filter water tank 201 tightly and fixedly installed under the bracket 1 by high-strength bolts. Each bolt is equipped with a corresponding nut and gasket, and the nut is tightened to the specified torque to ensure a firm connection. Inside the filter water tank 201, several filter plates 203 are evenly welded. The welding adopts the full-welding process to ensure the connection strength between the filter plate 203 and the inner wall of the filter water tank 201. The filter plate 203 can effectively intercept impurities and dust in the water. A slope 204 is integrally cast at the lower part of the inner wall to facilitate the flow and centralized discharge of sewage. The upper part of the filter water tank 201 is connected to the drainage tank 202 by welding, and the welding part is sealed to prevent water leakage. Multiple drainage grooves are opened on the surface of the drainage tank 202 to ensure the smooth discharge of water flow. In addition, a water inlet pipe 205 is provided on one side of the filter water tank 201 by means of pipeline connection. The pipeline connection is sealed with a sealing rubber ring to ensure no leakage and is used to supplement the water source. A water pump is installed at one end. The water pump and the circulating water pipe 206 are tightly connected by threading, and the thread is wound with raw tape to enhance the sealing performance. The other end of the circulating water pipe 206 is tightly connected to the distribution pipe 207 through a flange. A rubber sealing gasket is placed between the flanges and evenly fastened with bolts. Several atomizing nozzles 208 are inclinedly installed under the distribution pipe 207 to ensure that the nozzles can evenly spray water on the surface of the car door 9. When the water pump works, the water in the filter water tank 201 is pumped out, pumped into the distribution pipe 207 through the circulating water pipe 206, and then sprayed on the car door 9 in a fan shape by the atomizing nozzles 208 to achieve the cleaning of the surface of the car door 9. The filter plate 203 can filter impurities in the water, the slope 204 guides the sewage to flow to the drainage tank 202, and the drainage grooves drain the water, realizing the preparation for the recycling of water; The rotary motor 4 is fixedly installed under the moving plate 305 through a special motor mounting seat. The mounting seat, the moving plate 305 and the motor are all tightly connected by bolts. A support plate 501 is fixedly provided at its output end and tightly connected to the support plate 501 by key connection. The matching precision of the key and the keyway is relatively high to ensure the effective transmission of torque; The support device 5 includes a number of inclined sliding grooves 502 formed on the surface of the support plate 501. An electric lifting rod 503 is fixedly installed on one side of the support plate 501 by welding, and the welding is firm and reliable. The lower part of the electric lifting rod 503 is connected to the lifting plate 504 by bolts, and the bolts are equipped with lock nuts. Above one end of the lifting plate 504, a lifting connection plate 505 is fixedly provided by welding. In addition, the support device 5 further includes symmetrically installed lifting slide rails 506. A lifting slide rod 507 is adaptively arranged in the lifting slide rails 506. Symmetrically arranged lifting slide plates 508 adapted to the threads are provided on the surface of the lifting slide rod 507, and the thread fit is smooth. One side of each of the lifting slide plates 508 is fixedly connected to an adjusting rod 509 by welding. When the rotating motor 4 works, it drives the support plate 501 to rotate, and the angle of the car door 9 can be adjusted. The electric lifting rod 503 drives the relevant components to lift through the lifting plate 504 and the lifting connection plate 505. The adjusting rod 509 can move up and down along the lifting slide rod 507 driven by the lifting slide plate 508, and can also slide in the inclined sliding groove 502 at the same time. Through the cooperation of these structures, the position of the adsorption plate 605 can be flexibly adjusted to adapt to car doors 9 of different sizes and shapes; The adsorption device 6 includes a vacuum pump 601 fixedly installed on one side of the support plate 501 by bolts. The air inlet end of the vacuum pump 601 is threadedly connected to the adsorption air pipe 602, and the threaded part is well sealed to prevent air leakage. One end of the adsorption air pipe 602 is tightly connected to the branch air pipe 603 through a three-way joint. The three-way joint is firmly connected and sealed. A number of adsorption pipes 604 are evenly welded and distributed on one side of the branch air pipe 603. The welding ensures the connection strength and sealing performance. An adsorption plate 605 is fixedly installed above the adsorption pipe 604 by welding, and a suction cup 606 is fixedly installed below by threaded connection. The threaded connection ensures the stable installation of the suction cup 606. The adsorption plate 605 is movably installed on the surface of the adjusting rod 509. The adjusting rod 509 is provided with a smooth guiding groove, and the adsorption plate 605 can move smoothly therein. And a clamping rod is fixedly provided on one side of the adsorption plate 605. The clamping rod is movably adapted to the inclined sliding groove 502, so that the adsorption plate 605 can be adjusted according to the specific situation of the car door 9 to ensure that the suction cup 606 is closely attached to the surface of the car door 9 to achieve reliable adsorption. The air circulation device 8 includes an air circulation box 801 fixedly installed above the moving plate 305 by bolt connection. The bolts are evenly distributed and tightened. The interior of the air circulation box 801 is divided into an air passing channel 802 and an exhaust box 803 by welding. The welding is well sealed. A thick-hole air passing plate 804 is fixedly installed below the air passing channel 802, and an air passing motor 805 is installed above through a motor seat. The motor seat is firmly installed. The output end of the air passing motor 805 is staggeredly installed with a driving gear 806. The driving gear 806 is key-connected to the motor output shaft. The key connection ensures power transmission. The surface of the driving gear 806 is connected to a driven gear 808 through a transmission belt 807. The tension of the transmission belt 807 is precisely adjusted. A transmission fan 809 is fixedly installed above the driven gear 808 by welding. The air passing channel 802 is Z-shaped, and a vertical collection box 810 is movably arranged inside through clamping. A cover plate 811 is movably installed above the vertical collection box 810 through a hinge. The hinge rotates flexibly. The other end is movably clamped with a fine filter screen 812 through a card slot. The card slot is closely matched with the fine filter screen 812. Exhaust pipes 813 are symmetrically arranged on one side of the exhaust box 803. The lower part of the exhaust pipe 813 is fixedly connected to a circulation air pipe 814 by threaded connection. The thread is sealed. The circulation air pipe 814 is fixedly installed on one side of the moving plate 305 through a pipe clamp. The clamping force of the pipe clamp is moderate. A number of inclined circulation nozzles 815 are evenly welded and distributed below. The air passing motor 805 drives the driving gear 806 to rotate, and through the transmission belt 807, the driven gear 808 and the transmission fan 809 rotate, sucking the gas around the car door 9 into the air passing channel 802. The thick-hole air passing plate 804 and the fine filter screen 812 filter impurities and fog. The fog condenses into water and falls into the vertical collection box 810. The purified gas is blown out from the circulation nozzles 815 through the exhaust pipes 813 and the circulation air pipe 814 to blow dust and accelerate drying of the car door 9; The scraping device 10 includes scraping connection plates 1001 fixedly installed at both ends of the moving plate 305 by welding, and the welding strength meets the usage requirements. The scraping connection plates 1001 are connected to the scraper 1002 by bolts below, and the bolts are equipped with spring washers to prevent loosening. The scraper 1002 is in contact with the bottom of the filter water tank 201, and the contact part is wear-resistant. During the movement of the moving device 3, the scraper 1002 can move in the filter water tank 201 to scrape and move the water and dust in the tank to one end of the tank for subsequent treatment. The dryers 7 symmetrically arranged on the sides of the support device 5 cooperate with the circulating spray heads 815 to quickly and effectively dry the surface of the car door 9. The dryers 7 generate hot air, and the gas blown out by the circulating spray heads 815 assists the hot air to dry the car door 9. At the same time, the scraper 1002 cleans the impurities at the bottom of the filter water tank 201 driven by the moving plate 305; The specific working process is as follows: Before the installation work starts, the car doors 9 to be installed need to be arranged orderly and neatly at both ends of the device; Subsequently, an instruction is issued through the control device to start the moving device 3. At this time, the moving motor 302 starts to operate, and its output shaft drives the moving threaded rod 303 to rotate. Since the moving threaded rod 303 is threadedly adapted to the moving slide plate 304, under the rotation of the threaded rod, the moving slide plate 304 moves smoothly along the active slide rail 301. The movement of the moving slide plate 304 further drives the moving plate 305 fixedly connected thereto. At the same time, the rotating motor 4, the support device 5 installed below the moving plate 305, and the scraping device 10 and the dryer 7 at both ends of the moving plate 305 also move towards both ends of the device. When the adsorption device 6 moves to one end of the device with the support device 5, the suction cup 606 just contacts one side of the car door 9. Immediately afterwards, the control device starts the vacuum pump 601. The vacuum pump 601 quickly extracts the air inside the suction cup 606 through the adsorption air pipe 602, the branch air pipe 603, and the adsorption pipe 604, making the inside of the suction cup 606 in a vacuum state, so as to firmly adsorb the car door 9 and ensure that the car door 9 is stable and immovable during subsequent operations; After the car door 9 is adsorbed, the rotating motor 4 is started by using the control device. The output end of the rotating motor 4 is key-connected to the support plate 501. When the motor operates, it drives the support plate 501 to rotate, and then the support device 5 connected to the support plate 501 drives the adsorbed car door 9 to adjust the direction. By precisely controlling the rotation angle of the rotating motor 4, the car door 9 is adjusted to face the direction of the vehicle frame to meet the specific requirements for the subsequent installation of the car door 9 and ensure that the car door 9 can be accurately installed on the vehicle frame; After the angle of the car door 9 is adjusted in place, the control device starts the water pump. The water pump pumps out the water source stored in the filter water tank 201. The water source is transported to the distribution pipe 207 through the circulating water pipe 206. A number of atomizing nozzles 208 welded obliquely below the distribution pipe 207 evenly spray the water source on the surface of the car door 9 in a fan shape, realizing the preliminary cleaning of the car door 9. At the same time, the distribution pipe 207 moves up and down by means of the slide rails at both ends, ensuring that the entire surface of the car door 9 can be flushed in all directions, effectively removing various stains and impurities on the surface of the car door 9. During the movement of the moving device 3, the scraping connecting plates 1001 fixed below both ends of the moving plate 305 move synchronously. The scraping connecting plates 1001 drive the scraping plate 1002 below to move in the filter water tank 201. The scraping plate 1002 scrapes and moves the water and dust in the filter water tank 201 to one end of the tank. Subsequently, the water flows into the water storage tank. The filter plate 203 in the water storage tank filters the dust in the flowing water source, realizing the recycling of water resources and greatly reducing the waste of water resources; As the supporting device 5 rotates, the car door 9 that has completed cleaning is exactly in the middle position between the two dryers 7. At this time, the control device starts the dryer 7, and the dryer 7 starts to generate hot air to perform the drying operation on the surface of the car door 9. During the drying process, since water mist will be generated due to the evaporation of water, in order to accelerate the drying process and recover the mist, the control device starts the air passing motor 805. The driving gears 806 installed in a staggered manner at the output end of the air passing motor 805 rotate driven by the motor. The driving gears 806 drive the driven gears 808 to rotate through the transmission belt 807, and then the transmission fan 809 connected to the driven gears 808 rotates synchronously. The transmission fan 809 sucks the gas containing mist around the car door 9 below into the air passing channel 802. When the gas flows in the air passing channel 802, it first passes through the thick hole air passing plate 804. The thick hole air passing plate 804 can block larger impurities and dust in the gas. Subsequently, the gas continues to move forward and passes through the fine filter screen 812. The fine filter screen 812 further filters and isolates the gas. At the same time, the surface of the fine filter screen 812 blocks the mist with heat, causing the water condensate beads to form on the surface of the fine filter screen 812 when it meets cold. The water condensate beads finally fall into the vertical collection box 810. The purified gas enters the exhaust box 803 and is discharged to the circulating air pipe 814 through the exhaust pipe 813. Finally, it is discharged from the inclined circulating nozzles 815 evenly distributed below the circulating air pipe 814. The gas discharged from the circulating nozzles 815 directly faces the car door 9, not only blowing dust on the car door 9 but also further accelerating the drying speed of the car door 9; The mobile device 3 continues to move, precisely moving the device adsorbed with the car door 9 to the area to be installed. At this time, the operator installs the car door 9 accurately on the vehicle frame according to the installation process requirements. After the installation of the car door 9 is completed, the control device issues an instruction to control the vacuum pump 601 to stop running, the internal pressure of the suction cup 606 returns to normal, and the adsorption device 6 cancels the adsorption of the car door 9. Thus, the installation process of the car door 9 is completed; The mobile device 3 moves to one end, and the control device controls the rotary motor 4 to rotate again. The rotary motor 4 drives the support plate 501 to rotate, returning the device to its initial state, that is, the state where it can adsorb a new car door 9, making full preparations for the next adsorption and installation operation of the car door 9, and realizing the recycling of the device.

[0026] Embodiment 2: Please refer to Figures 1-10 , a technical solution provided by the present invention: A working method of a clamping device for installing a car door, including the following steps: S1: First, arrange the car doors 9 to be installed evenly at both ends of the device, making preparations for subsequent adsorption operations, ensuring the accurate position of the car doors 9, and facilitating the adsorption by the adsorption device 6; S2: Start the mobile device 3 through the control device. The mobile motor 302 starts to work, driving the mobile threaded rod 303 to rotate, causing the mobile slide plate 304 threadedly adapted to the mobile threaded rod 303 to move along the active slide rail 301. The movement of the mobile slide plate 304 drives the mobile plate 305, as well as the rotary motor 4, the support device 5, the scraping devices 10 on both sides, and the dryer 7 installed below it to move towards both ends of the device. The support device 5 drives the adsorption device 6 to move during the movement; When the adsorption device 6 moves to one end of the device, the suction cup 606 comes into contact with one side of the car door 9. At this time, the control device starts the vacuum pump 601. The vacuum pump 601 extracts the air inside the suction cup 606 through the adsorption air pipe 602, the branch air pipe 603, and the adsorption pipe 604, making the inside of the suction cup 606 in a vacuum state, thereby realizing the firm adsorption of the car door 9; S3: Use the control device to start the rotary motor 4. The rotary motor 4 drives the support plate 501 to rotate, and then the support device 5 drives the adsorbed car door 9 to adjust the direction, adjusting the car door 9 to face the vehicle frame to meet the specific requirements for the subsequent installation of the car door 9 and ensuring that the car door 9 can be accurately installed on the vehicle frame; S4: After the direction adjustment of the car door 9 is completed, the control device starts the water pump. The water pump extracts the water source in the filter water tank 201 and transports it to the distribution pipe 207 through the circulating water pipe 206; The distribution pipe 207 evenly sprays the water source on the surface of the car door 9 through the atomizing nozzles 208. At the same time, the distribution pipe 207 is moved up and down through the slide rails at both ends to ensure that the entire surface of the car door 9 can be comprehensively rinsed to remove stains and impurities on the surface of the car door 9; During the movement of the mobile device 3, the scraping connection plates 1001 under both ends of the mobile plate 305 move accordingly. The scraping connection plates 1001 drive the lower scraping plates 1002 to move in the filter water tank 201, scraping and moving the water and dust in the filter water tank 201, so that the water moves to one end of the filter water tank 201 and flows into the water storage tank. The filter plate 203 in the water storage tank filters the dust in the inflowing water source, realizing the recycling of water resources and reducing the waste of water resources; Due to the rotation of the support device 5, after the rinsing is completed, the car door 9 will be in the middle position between the two dryers 7. At this time, the control device starts the dryer 7, and the dryer 7 dries the surface of the car door 9; During the drying process, since drying will generate water mist, the control device starts the air passing motor 805. The air passing motor 805 drives the transmission fan 809 to rotate. The transmission fan 809 sucks the gas around the lower car door 9 and discharges the gas to the exhaust box 803 through the air passing channel 802; When the gas passes through the exhaust box 803, the thick-hole air passing plate 804 will block impurities and dust, and the fine filter screen 812 further filters and isolates the gas. At the same time, the surface of the fine filter screen 812 will block the hot mist, causing water condensate beads to form on the surface of the fine filter screen 812, and the water condensate beads will drop into the vertical collection box 810; The gas in the exhaust box 803 is discharged to the circulating air pipe 814 through the exhaust pipe 813. The circulating air pipe 814 is discharged through the circulating nozzle 815, and the circulating nozzle 815 faces the position of the car door 9. The discharged gas blows and dusts the car door 9, and at the same time accelerates the drying speed of the car door 9; S5: The mobile device 3 continues to move, moves the device adsorbing the car door 9 to the installation area to be installed. The operator accurately installs the car door 9 on the vehicle frame. After the installation of the car door 9 is completed, the control device controls the vacuum pump 601 to stop running, so that the adsorption device 6 cancels the adsorption of the car door 9, and the installation process of the car door 9 is completed; S6: The mobile device 3 moves to one end. The control device controls the rotation motor 4 to rotate, driving the support plate 501 to rotate, so that the device returns to the state where it can adsorb a new car door 9 again, prepares for the next adsorption and installation operation of the car door 9, and realizes the recycling of the device.

8. A working method of a clamping device for automobile door installation, characterized in that: It includes the following steps: S1: Arrange the car doors (9) evenly at both ends of the device to prepare for subsequent adsorption operations; S2: Use the control device to control the operation of the moving device (3). The moving motor (302) in the moving device (3) drives the moving threaded rod (303) to rotate, so that the moving slide plate (304) threadedly adapted to the moving threaded rod (303) moves along the active slide rail (301), thereby driving the moving plate (305) and the rotating motor (4), the support device (5), the scraping devices (10) on both sides and the dryer (7) installed below to move towards both ends of the device. The support device (5) simultaneously drives the adsorption device (6) to move. When the adsorption device (6) moves to one end of the device, the suction cup (606) contacts one side of the car door (9). At this time, the control device is used to control the operation of the vacuum pump (601). The vacuum pump (601) evacuates the air inside the suction cup (606) through the adsorption air pipe (602), the branch air pipe (603) and the adsorption pipe (604), and is in a vacuum state, so as to adsorb the car door (9). S3: Use the control device to control the rotation of the rotary motor (4). The rotary motor (4) drives the support plate (501) to rotate, and then the support device (5) drives the adsorbed car door (9) to adjust the direction, so that the car door (9) faces the frame direction to meet the subsequent installation requirements. S4: After the direction adjustment of the car door (9) is completed, use the control device to control the operation of the water pump. The water pump extracts the water source in the filter water tank (201) and discharges it to the distribution pipe (207) through the circulating water pipe (206). The distribution pipe (207) sprays the water source on the surface of the car door (9) through the atomizing nozzles (208). At the same time, the distribution pipe (207) is moved up and down through the slide rails (306) at both ends to ensure that the surface of the car door (9) can be comprehensively washed with water. Moreover, during the movement of the moving device (3), the scraping connecting plates (1001) under both ends of the moving plate (305) move accordingly. The scraping connecting plates (1001) drive the scraping plates (1002) below to move in the filter water tank (201), scrape and move the water and dust generated in the filter water tank (201), so that the water moves to one end of the filter water tank (201) and flows into the water storage tank. The filter plate (203) in the water storage tank filters the dust in the water source for the recycling of water resources. At the same time, due to the rotation of the support device (5), after the washing is completed, the car door (9) is in the middle position between the two dryers (7). Use the control device to control the operation of the dryer (7). The dryer (7) dries the surface of the car door (9). During the drying process, water mist is generated due to drying. Use the control device to control the operation of the air passing motor (805). The air passing motor (805) drives the transmission fan (809) to rotate. The transmission fan (809) sucks the gas around the car door (9) below and discharges the gas to the exhaust box (803) through the air passing channel (802). When the gas passes through the exhaust box (803), the thick-hole air passing plate (804) blocks the impurity dust, and the fine filter screen (812) further isolates the gas. At the same time, the surface of the fine filter screen (812) blocks the hot fog, causing water condensation beads to be generated here. The water condensation beads drop into the vertical collection box (810). The gas in the exhaust box (803) is discharged to the circulating air pipe (814) through the exhaust pipe (813). The circulating air pipe (814) is discharged through the circulating nozzle (815), and the circulating nozzle (815) faces the position of the car door (9). The discharged gas blows dust on the car door (9) and accelerates the drying of the car door (9). S5: The mobile device (3) moves to the area to be installed, and the operator installs the vehicle door (9) on the vehicle frame. After the installation is completed, the control unit stops the operation of the vacuum pump (601) to cancel the adsorption of the adsorption device (6) on the vehicle door (9). S6: The mobile device (3) moves to one end, and the control device is used to control the rotation of the rotary motor (4) to drive the support plate (501) to rotate, so that the device is in a state where it can adsorb a new vehicle door (9) again, and is ready to perform the adsorption operation on the new vehicle door (9).
