Description

TECHNICAL FIELD

[0001] The utility model relates to hardware machining technology especially a safe paint spraying and drying integrated device. BACKGROUND

[0002] In the production and processing of hardware fittings such as metal plates, in order to enhance the appearance, corrosion resistance and meet the specific design requirements, the plate usually needs to be painted and dried.

[0003] In the prior art, paint spraying and drying are usually operated independently in two different processing rooms, which occupies production space and reduces production efficiency. Based on the above factors, the Chinese utility model patent with publication number CN219816795U discloses a paint spraying and drying integrated machine, which can simultaneously paint multiple hardware products. When the hardware product is painted, the blower and the heating resistance wire are started, the blower generates airflow through the heating resistance wire to blow against the hardware product, which accelerates the drying speed of the paint on the surface of the hardware product, thereby improving the production efficiency. However, the device can only paint and dry one side of the hardware plate, and manual turning is required, which increases the probability of dust entering the room, increases the intensity of workers, and affects the quality of paint spraying and drying. Therefore, the Chinese utility model patent with publication number CN220780951U discloses a dust-free paint spraying and drying integrated room. The second motor drives the screw rod to rotate, so that the two clamping plates are close to each other, the plate is clamped, then the second cross frame is lifted by the electric telescopic rod, the second cross frame is rotated by the motor, and then the second cross frame is lowered by the electric telescopic rod, completing the turning of the plate. Manual operation is not required, which reduces the burden on workers and realizes efficient paint spraying and drying of the plate workpiece.

[0004] However, during paint spraying and drying, the water and harmful solvents in the paint volatilize and accumulate in the paint drying room, which cannot be discharged in time. With the increase of paint spraying and drying time, the accumulated harmful substances affect the subsequent paint spraying and drying of the plate, resulting in a decrease in the quality and efficiency of paint spraying and drying. Furthermore, since drying requires heating the plate, the internal environment of the drying room is isolated from the outside, resulting in a high temperature in the drying room. After opening the door, the operator is easily scalded by the hot air in the paint drying room. In addition, some harmful substances volatilize into the external environment, polluting the surrounding environment and affecting the respiratory health of surrounding workers.

[0005] Therefore, it is necessary to improve the safety of the existing paint spraying and drying equipment. UTILITY MODEL CONTENTS

[0041] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0042] like Figures 1-18 As shown, the safety-type integrated paint spraying and drying device of this utility model includes:

[0043] The processing box 1 includes a box body 11, one side of which is open and rotatably connected to a door 12. The length direction of the open side of the box body 11 is the first direction. A locking member 13 is provided between the box body 11 and the door 12 to lock the two together to form the inner cavity of the processing box 1.

[0044] The processing assembly comprises a paint spraying unit 2 and a heating unit 3, the paint spraying unit 2 comprises a downward spraying head 21 arranged in the box 11, the spraying head 21 is fixedly connected with a conveying pipe 22 penetrating the inner wall or the side wall of the box 11, the conveying pipe 22 is used for connecting a paint supply device, the heating unit 3 comprises an infrared lamp 31 arranged in the box 11;

[0045] The storage assembly is arranged below the processing assembly, the storage assembly comprises a translation frame 4, a translation unit 5, a turnover unit 6 and a driving unit 7, the turnover unit 6 is distributed along a first direction, the turnover unit 6 comprises two turnover shells 61 symmetrically distributed and rotating above the translation frame 4 and a pressure regulating unit arranged below the two turnover shells 61, the symmetry planes of the two turnover shells 61 are parallel to the open side of the box 11, one side of the two turnover shells 61 is open and the rotation axis is parallel to the first direction, the driving unit 7 drives the two turnover shells 61 to rotate between a laying position and an access position, in the laying position, the open sides of the two turnover shells 61 are both horizontal and located at the top surfaces of the corresponding turnover shells 61, in the access position, the open sides of the two turnover shells 61 are both vertical and face each other, the distance between the open sides of the two turnover shells 61 is greater than or equal to the thickness of the plate 9, the pressure regulating unit is used for regulating the air pressure in the turnover shells 61; the translation unit 5 drives the translation frame 4 to move along a horizontal direction perpendicular to the first direction so that the open side of one of the turnover shells 61 in the laying position faces the processing assembly; preferably, the pressure regulating unit is a bidirectional air pump 62, two ends of the bidirectional air pump 62 are fixedly connected with the two turnover shells 61 respectively.

[0046] When the device is in operation, first, the locking member 13 is removed from the locking connection between the box 11 and the box door 12, then the box door 12 is rotated so that the box door 12 is opened, the translation unit 5 pushes the translation frame 4 to move towards the open side of the box 11, the two turnover shells 61 in the turnover unit 6 are adjusted to the access position by the driving unit 7, so that the two turnover shells 61 are vertically arranged and the open sides face each other, the plate 9 to be painted is placed between the two turnover shells 61, the bottom of the plate 9 is supported by the translation frame 4, as shown in Figure 3 and Figure 4 .

[0047] After the plate 9 is placed, the translation unit 5 pulls the translation frame 4 to move towards the inside of the box 11, then the box door 12 is closed after the box door 12 closes the open side of the box 11, the box door 12 and the box 11 are locked and connected by the locking member 13, so that the box door 12 and the box 11 form a sealed processing environment.

[0048] Afterwards, the bidirectional air pump 62 starts, and air in one of the two turning shells 61 connected by the pump is transported to the other turning shell 61, so that in the two turning shells 61 of the turning unit 6, one of them is continuously pumped out of air, the pressure decreases, and the other is continuously supplied with air, the pressure increases, thereby making one side of the two sides of the board 9 be subjected to the adsorption force of the turning shell 61 with reduced pressure, and the other side be subjected to the pushing force of the turning shell 61 with increased pressure, so that the board 9 is adsorbed and fixed to the open side of the turning shell 61 with reduced pressure, and the board 9 remains relatively fixed to the turning shell 61.

[0049] On the basis of the above, the driving unit 7 starts, and the two turning shells 61 in the turning unit 6 are simultaneously adjusted to the flat position, and it needs to be noted that in the utility model, the turning shell 61 is flat, and the length and width dimensions are respectively smaller than the length and width dimensions of the board 9, so that in the flat position, the board 9 is horizontally arranged and covers the top surface of the turning shell 61 with reduced pressure, that is, the open side of the top of the turning shell 61. The translation unit 5 drives the translation frame 4 to move, so that the board 9 on the top of the turning shell 61 can face the paint spraying unit 2 and the heating unit 3 in the processing assembly.

[0050] After the horizontal position of the board 9 is adjusted, the paint supply device connected with the conveying pipe 22 operates, paint is conveyed to the spray head 21 through the conveying pipe 22, so that the paint is sprayed in mist form on the surface of the board 9, and the paint spraying operation is realized. After the single-side paint spraying is completed, the infrared lamp 31 in the heating unit 3 starts, and infrared rays are radiated to the top surface of the board 9, that is, the paint spraying surface, so that the top surface of the board 9 is heated by the infrared rays, and the paint is dried after being heated.

[0051] After the single-side paint spraying and drying operation of the board 9 are completed, the driving unit 7 is started again, and the two turning shells 61 in the turning unit 6 are simultaneously adjusted to the access position, in which the two turning shells 61 face each other and the open sides are vertically arranged, so that the board 9 between the two turning shells 61 is vertically arranged. Then the bidirectional air pump 62 is driven, and the input state of the two ends of the bidirectional air pump 62 is adjusted, so that the end that originally pumps out air performs exhaust, and the end that originally exhausts air performs pumping, so that the pressure change of the two turning shells 61 is opposite to that before, the turning shell 61 opposite to the paint spraying surface of the board 9 is continuously supplied with air, which changes from reduced pressure to increased pressure, and air flows out of the open side of the turning shell 61, pushing the board 9, and the turning shell 61 adjacent to the paint spraying surface of the board 9 is continuously pumped out of air, which changes from increased pressure to reduced pressure, and after the air is pumped out, negative pressure is formed, adsorbing the paint spraying surface of the board 9. Then the driving unit 7 is started again, and the two turning shells 61 in the turning unit 6 are simultaneously adjusted to the flat position, at this time, the paint spraying surface of the board 9 is downward and is the bottom surface, and the top surface of the board 9 is not painted.

[0052] In the above case, the plate 9 is turned over, and the horizontal position of the plate 9 is changed, the translation frame 4 is driven by the translation unit 5 to move horizontally, and the horizontal position of the translation frame 4 and the plate 9 is adjusted, so that the top surface of the plate 9 faces the processing assembly, and then the paint spraying unit 2 and the heating unit 3 in the processing assembly complete the paint spraying and drying treatment on the other surface of the plate 9 in turn.

[0053] After the plate 9 is turned over and the horizontal position of the translation frame 4 is adjusted, the paint spraying unit 2 and the heating unit 3 complete the double-sided paint spraying and drying operation of the plate 9, the locking operation of the box body 11 and the box door 12 by the locking piece 13 is removed, the box door 12 is rotated, and the product plate 9 after double-sided paint spraying and drying is taken out.

[0054] Compared with the prior art, the device can adjust the positions of the two turnover shells 61 through the driving unit 7 at one time, when the two turnover shells 61 are in the access station, the air pressure of the two turnover shells 61 is adjusted through the pressure regulating unit, that is, the bidirectional air pump 62, so that the air pressure of one of the turnover shells 61 increases while the air pressure of the other turnover shell 61 decreases, the plate 9 is conveniently close to the turnover shell 61 with reduced air pressure, and then the two turnover shells 61 are adjusted to the flat laying station through the driving unit 7, so that the plate 9 is kept in a horizontal state, the translation frame 4 is driven by the translation unit 5 to move, so that the horizontal plate 9 moves to the lower side of the processing assembly, and the paint spraying unit 2 and the heating unit 3 are conveniently arranged in sequence to perform paint spraying and drying treatment on the top surface of the plate 9. In this way, the positions of the two turnover shells 61 are adjusted, and the air pressure of the turnover shells 61 is adjusted by the pressure regulating unit, so that the plate 9 is smoothly turned over, the storage rack assembly of the device is provided with a plurality of turnover units 6, the driving unit 7 acts on the plurality of turnover units 6 at the same time, and then the plate 9 corresponding to the plurality of turnover units 6 can be turned over at one time, and the horizontal position of the translation frame 4 and the plate 9 is adjusted by the translation unit 5, so that the paint spraying unit 2 and the heating unit 3 are conveniently arranged for paint spraying and drying operation, thereby realizing mass production of the plate 9, and improving the processing efficiency.

[0055] In the utility model, the plate 9 is turned over by the turnover unit 6, and the horizontal position of the translation frame 4 is adjusted by the translation unit 5, so that the plate 9 is kept in a horizontal state, and the plate 9 is moved to the lower side of the processing assembly by the translation unit 5, so that the paint spraying unit 2 and the heating unit 3 are conveniently arranged in sequence to perform paint spraying and drying treatment on the top surface of the plate 9.

When the lock pin 133 is separated from the lock pipe 131, the box door 12 can be rotated. The box door 12 is provided with an observation window 121, which facilitates the observation of the processing condition of the plate 9 in the processing box 1. A control button is further provided below the observation window 121, which facilitates the control of the operation of the heating unit 3, the translation unit 5, the overturning unit 6, the driving unit 7 and other components in the box body 11. The end of the box door 12 away from the rotating seat 116 is provided with a handle 122, which facilitates the rotation of the box door 12.

[0056] The specific structure of the processing assembly is as shown in Figures 3-6 As shown, the processing assembly includes a conveying pipe 22, a main horizontal pipe 23, a branch vertical pipe 24, a branch horizontal pipe 25 and a fixing sleeve 26. The conveying pipe 22 is fixedly penetrated through the top wall of the box body 11 in the vertical direction. The top end of the conveying pipe 22 is used for connecting a paint supply device. The bottom end of the conveying pipe 22 is fixedly communicated with the main horizontal pipe 23 extending in the first direction and closed at both ends. The two ends of the main horizontal pipe 23 are fixedly connected with the fixing sleeve 26 sleeved thereon. The fixing sleeve 26 is fixed below the top wall of the box body 11. The lower side of the main horizontal pipe 23 is fixedly communicated with the branch vertical pipes 24 distributed along the length direction of the main horizontal pipe 23 at equal intervals and extending downward in the vertical direction. The bottom end of the branch vertical pipe 24 is fixedly communicated with the branch horizontal pipe 25 extending in the horizontal direction perpendicular to the first direction and closed at both ends. The lower side of the branch horizontal pipe 25 is fixedly communicated with the spray heads 21 distributed along the length direction of the branch horizontal pipe 25 at equal intervals.

[0057] After the above structure is adopted, when paint spraying is performed, the paint supply device delivers paint through the conveying pipe 22. The paint is sequentially delivered through the main horizontal pipe 23, the branch vertical pipe 24 and the branch horizontal pipe 25, and then uniformly sprayed downward from the spray heads 21 to adhere to the top surface of the plate 9 to form a paint layer to be dried.

[0058] Further improvement is that the heating unit 3 further includes a telescopic unit 32 arranged on the box body 11 and driving the infrared lamp 31 to move in the vertical direction. The two ends of the movement path of the infrared lamp 31 are located above the spray heads 21 and below the spray heads 21, respectively. The heating unit 3 further includes a distance sensor 33 for detecting the height position of the spray heads 21.

[0059] Specifically, the heating unit 3, the telescopic unit 32 is provided with four, rectangular array distribution in the box 11, the telescopic unit 32 is vertically downward electric push rod, the shell of telescopic unit 32 is fixed on the top of the box 11, the piston rod is sealed through the top wall of the box 11 and is fixedly connected with the horizontal adjusting plate 35, the adjusting plate 35 is fixed with the upward distance sensor 33, the distance sensor 33 is towards the inner top wall of the box 11, the infrared lamp 31 is connected with the downward lampshade 36, the length direction of infrared lamp 31 and lampshade 36 is perpendicular to the first direction horizontal direction, the lampshade 36 is fixed below the adjusting plate 35 by the vertical rod 34, the adjusting plate 35 is sealed and sleeved on the outer branch vertical pipe 24 and is in sliding fit with the branch vertical pipe 24;The infrared lamp 31 is distributed in the first direction equidistantly and side by side, the projection of infrared lamp 31 on the horizontal plane is equidistantly distributed with the projection of the branch horizontal pipe 25 on the horizontal plane.

[0060] After the above design, through the equidistantly distributed infrared lamp 31, the top surface of the plate 9 is uniformly heated during the heating and drying process, the telescopic unit 32 can control the adjusting plate 35 to move along the branch vertical pipe 24 in the axial direction, that is, the vertical direction, and then drive each infrared lamp 31 to move synchronously by the vertical rod 34 and the lampshade 36, and the top end and the bottom end of the moving path of the infrared lamp 31 are located above and below the nozzle 21 respectively, so that the infrared lamp 31 has sufficient movement range during the heating process, and the height position of the infrared lamp 31 can be detected by the distance sensor 33 detecting the distance position between the adjusting plate 35 and the inner top wall of the box 11.

[0061] In the heating unit 3 of the utility model, the height position of the infrared lamp 31 is controlled by the telescopic unit 32, so that the position of the infrared lamp 31 and the paint layer on the top surface of the target, that is, the plate 9, can be controlled.

[0062] The first stage, that is, the initial preheating stage, the telescopic unit 32 drives the infrared lamp 31 to move upwards, increases the height difference between the infrared lamp 31 and the plate 9, reduces the received infrared rays of the metal plate 9, so that the plate 9 can be gradually heated, and the thermal stress or surface overheating of the plate 9 caused by sudden high-temperature heat radiation can be avoided, and the internal temperature distribution of the plate 9 is more uniform through preheating, so as to prepare for the subsequent heating process.

[0063] The second stage, that is, the middle heating stage, the telescopic unit 32 drives the infrared lamp 31 to move downwards, reduces the height difference between the infrared lamp 31 and the plate 9, can accelerate the drying speed and improve the drying efficiency, because the plate 9 has been preheated before, the internal temperature distribution is relatively uniform, so that the plate 9 can withstand higher heat radiation intensity without causing surface overheating or excessive internal stress.

[0064] In the third stage, the telescopic unit 32 drives the infrared lamp 31 to move upward, increases the height difference between the infrared lamp 31 and the plate 9, gradually cools the plate 9, and helps the plate 9 to cool slowly, avoids thermal stress or surface caused by sudden cooling of the plate 9, and gradually cools the plate 9 to make the temperature distribution inside the plate 9 more uniform, and improves the drying quality.

[0065] Therefore, in the utility model, the telescopic unit 32 controls the infrared lamp 31 to move up and down, adjusts the height distance from the plate 9, realizes the drying heating mode that the infrared lamp 31 is far away from the plate 9 in the early stage and the late stage and the infrared lamp 31 is close to the plate 9 in the middle stage, compared with the existing fixed distance heating mode, has more uniform temperature distribution, through preheating and gradual cooling transition, makes the heat distribution inside the plate 9 more uniform, reduces the risk caused by thermal stress and surface temperature sharp change, through the drying mode that the plate 9 is close in the middle stage, can accelerate the drying speed, improves the drying efficiency, in short, adopts the above structure, can consider drying efficiency and drying quality, guarantees that the drying operation is safe and efficient.

[0067] Because the box body 11 needs to be painted and dried, the isolation pipe 111 can protect the translation unit 5, ensure the safe operation of the translation unit 5, and reduce the influence of painting and heating on the translation unit 5.

[0068] Further improvement is, the translation frame 4 is provided with a support roller 46 abutting and contacting with the inner bottom wall of the box body 11. By setting the support roller 46, the translation frame 4 can be supported to move in the box body 11 of the processing box 1, which is convenient to move, thereby reducing the power consumption of the translation unit 5.

[0069] The specific structure of the translation frame 4 is as shown in Figure 11As shown, the translation frame 4 comprises an upper horizontal plate 41 and a lower horizontal plate 42 arranged in sequence from top to bottom, both of which are horizontally arranged and the length direction is the first direction, and the support rollers 46 are arranged at the four corners of the lower horizontal plate 42; the two ends of the upper horizontal plate 41 and the lower horizontal plate 42 are fixedly connected through the legs 43 extending in the vertical direction; the top surface of the upper horizontal plate 41 is also provided with a protruding strip 44 extending in the first direction, and the width direction of the protruding strip 44 is the vertical direction, which is used to support the plate 9 between the two turnover shells 61 when the two turnover shells 61 are moved to the access station (as Figure 9 As shown, the upper horizontal plate 41 is also provided with equally spaced partition plates 45 in the first direction, and the partition plates 45 are vertically arranged and the distribution interval is consistent with the width size of the plate 9, which facilitates positioning of the plate 9 and avoids left and right deviation of the plate 9.

[0070] The upper side of the lower horizontal plate 42 is also fixedly provided with two sliding sleeves 48, and the box body 11 is also fixedly provided with two guide rails 117 corresponding to the two sliding sleeves 48, the guide rails 117 are inverted U-shaped, the two ends of the guide rails 117 are fixed to the upper side of the inner bottom wall of the box body 11, the middle part extends in the horizontal direction perpendicular to the first direction and is in sliding cooperation with the corresponding sliding sleeve 48, so that when the translation unit 5 operates, the translation frame 4 can move smoothly along the horizontal direction perpendicular to the first direction.

[0071] Further improvement is that the distance between the open sides of the two turnover shells 61 at the access station is equal to the thickness of the plate 9. As shown, Figure 9 After adopting this structure, it is ensured that when the two turnover shells 61 are rotated to the access station, the plate 9 is accurately inserted between the two turnover shells 61 and the adjacent two partition plates 45, the top of the plate 9 is supported by the protruding strip 44, and the open sides of the two turnover shells 61 are respectively attached to the two surfaces of the plate 9, when the bidirectional air pump 62 is started, the adsorption force of one of the turnover shells 61 on the plate 9 and the thrust of the other turnover shell 61 on the plate 9 are increased, so that the plate 9 can be firmly attached to the turnover shell 61 with reduced pressure, which is conducive to the smooth turnover of the plate 9.

[0072] Further improvement is that the driving unit 7 comprises a lifting mechanism 71 arranged on the translation frame 4 and a transmission mechanism 72 corresponding to the turnover unit 6, and the transmission mechanism 72 comprises a transmission rod 721 hinged to the output end of the lifting mechanism 71 and hinged to the two turnover shells 61.

[0073] Specifically, as shown, Figure 9 When the driving unit 7 operates, the lifting mechanism 71 acts as a power source and acts on the lower end of the transmission rod 721, which drives the turnover shell 61 to rotate and realizes flexible rotation switching of the turnover shell 61 between the flat laying station and the access station.

[0074] A further improvement is that the lifting mechanism 71 includes a lifting motor 711 fixedly connected to the translation frame 4 and pointing upwards, a lifting screw 712 coaxially connected to the output end of the lifting motor 711, a lifting sleeve 713 threadedly connected to the lifting screw 712, and a lifting bar 714 fixed to the top of the lifting sleeve 713 and extending along a first direction. The lifting bar 714 is rotatably connected to the transmission rod 721. The lifting mechanism 71 also includes a protective cylinder 715 extending in the vertical direction. The protective cylinder 715, the translation frame 4, and the lifting sleeve 713 enclose a protective cavity surrounding the lifting motor 711 and the lifting screw 712.

[0075] Specifically, such as Figures 11-14 As shown, in the lifting mechanism 71, the lifting motor 711 is fixed above the middle of the lower horizontal plate 42 and is upwardly oriented. The output end of the lifting motor 711 is coaxially connected to a lifting screw 712 extending in the vertical direction. The lifting screw sleeve 713 is threadedly connected to the lifting screw 712 and has a lifting bar 714 extending in the first direction fixed at its top end. The two ends of the lifting bar 714 are slidably sleeved on two support legs 43. The transmission mechanism 72 includes a connecting frame 722 and a transmission rod 721 hinged to both ends of the connecting frame 722. The lifting bar 714 is fixedly connected through the connecting frame 722. Connecting frame 722; bidirectional air pump 62 is fixed directly below connecting frame 722; a connecting pipe 614 is fixedly connected to the side of the flip shell 61 facing away from the open side, a first rotating arm 615 is fixed to the side of the connecting pipe 614 adjacent to the protrusion 44, a second rotating arm 616 is fixed to the side of the flip shell 61 adjacent to the protrusion 44, the second rotating arm 616 is rotatably connected to a connecting seat 617, the connecting seat 617 is fixed above the upper horizontal plate 41; the two ends of the bidirectional air pump 62 are respectively connected to the corresponding connecting pipes 614 of the two flip shells 61 through two hoses 621.

[0076] With the above structure, the flexible deformation of the hose 621 allows the two ends of the bidirectional air pump 62 to maintain good communication with the corresponding connecting pipes 614 of the two flip shells 61 after the flip shell 61 rotates. In the lifting mechanism 71, the protective cylinder 715 and the lifting screw sleeve 713 isolate and protect the lifting motor 711 and the lifting screw 712, preventing them from being affected by painting and drying heating. After the lifting motor 711 starts running, it drives the lifting screw 712 to rotate, acting on the lifting screw sleeve 713. Through the guiding action of the support leg 43, the lifting bar 714 moves smoothly up and down in the vertical direction, thereby driving the connecting frame 722 to move smoothly up and down, changing the height position of the lower end of the transmission rod 721. This allows the flip shell 61 to rotate under the rotational connection of the second rotating arm 616 and the connecting seat 617, adjusting the position of the flip shell 61 to achieve the workstation adjustment of the plate 9. The protective cylinder 715 is connected to the output end of the translation unit 5, so that after the translation unit 5 starts running, the translation frame 4 moves horizontally through the protective cylinder 715.

[0077] Further improvement is that the displacement sensor 47 is arranged on the side wall of the protection cylinder 715 facing away from the open side of the box body 11, and the displacement sensor 47 faces the inner wall of the open side of the box body 11, so that the displacement sensor 47 can detect the horizontal movement distance and position of the protection cylinder 715, and facilitate the adjustment of the board 9 on one of the turnover shells 61 under the flat paving station to the directly below the processing assembly.

[0078] Further improvement is that the two turnover shells 61 are provided with electric heating nets 63.

[0079] After the paint spraying is completed and the top surface of the board 9 is heated and dried by the infrared lamp 31, the bidirectional air pump 62 is started to extract the air in the turnover shell 61 with no cover on the open side and slowly convey it to the other turnover shell 61, and the electric heating nets 63 in the two turnover shells 61 are powered on, so that the air is heated and warmed after passing through the electric heating nets 63 in the two turnover shells 61, and acts on the bottom surface of the board 9, so that the bottom surface of the board 9 is heated and warmed. In this way, during the drying process, the double-sided heating of the board 9 can be realized, and compared with the heating of only the top surface of the board 9, the double-sided heating can ensure that the heat is more evenly distributed in the board 9, thereby reducing the uneven drying problem caused by uneven heat distribution. In addition, after the bidirectional air pump 62 is operated, the airflow generated can promote the flow of hot air in the processing box 1, further promoting the uniformity of the heating of the board 9. The infrared lamp 31 uses radiation heating, which can ensure that the inside and surface of the board 9 can be uniformly heated due to the penetration and radiation of infrared rays. In addition, due to the double-sided heating, the heating area of the board 9 is increased, thereby shortening the drying time, and compared with single-sided heating, the water and solvent in the paint on the surface of the board 9 can be removed more quickly, thereby improving the drying efficiency.

[0080] Further improvement is that the turnover shell 61 is provided with a flow dividing plate 611, the circumferential outer edge of the flow dividing plate 611 is fixedly connected with the circumferential inner wall of the turnover shell 61, and the flow dividing plate 611 is densely provided with flow dividing through holes 6111.

[0081] By arranging the flow dividing plate 611 densely provided with flow dividing through holes 6111, the adsorption force on the board 9 is more uniform when the board 9 is adsorbed, and the deformation of the board 9 is reduced. In addition, during the heating and drying process, the hot air uniformly acts on the surface of the board 9 by using the flow dividing plate 611, thereby ensuring the uniformity of the heating of the bottom surface of the board 9.

[0083] Specifically, as shown in Figure 13 and Figure 14 , the shunt plate 611 can also protect the electric heating net 63, preliminarily filter the air entering the turnover shell 61, reduce the dust and impurities on the electric heating net 63, and ensure the safe operation of the electric heating net 63; the uniformly distributed communication holes 613 are arranged on the circumferential side wall of the turnover shell 61, and the power of the bidirectional air pump 62 during operation is reduced, so that when the turnover shell 61 discharges gas, the gas can be discharged from the communication hole 613 after contacting the bottom surface of the plate 9, avoiding blowing the plate 9; the buffer pad 612 is a rubber pad and a rectangular frame structure, when the two turnover shells 61 rotate to the storage and retrieval stations, the bidirectional air pump 62 operates at high power, so that the plate 9 is firmly adsorbed on the buffer pad 612 of one of the turnover shells 61, not only that, the flexible contact is realized through the buffer pad 612, avoiding the abrasion of the plate 9 and the turnover shell 61 due to rigid contact, and reducing the product quality.

[0087] When the circulating filtering assembly 8 is running, the air suction pump 81 is started to suck the air in the processing box 1 and deliver it to the air inlet cavity of the filtering shell 82, the filter screen frame 84 in the filtering shell 82 is used to store filtering material, preferably activated carbon particles, which filter out harmful substances in the air, so that the clean air returns to the processing box 1 through the backflow pipe 83, ensuring the cleanliness of the gas in the processing box 1, ensuring the quality of paint spraying and drying, while reducing the residue of harmful substances in the processing box 1 to ensure the health of the surrounding air environment and avoid affecting the respiratory health of surrounding personnel.
