Description

Technical Field

[0001] The invention belongs to the technical field of spraying equipment, in particular to a complete set of cabinet automatic spraying equipment. Background Art

[0002] Spray painting (also known as painting) is very important for furniture manufacturing. There are generally two ways to spray paint, manual spray painting and mechanical spray painting. The manual spray painting method is that the operator directly sprays paint on the surface of the furniture through the nozzle, which is not efficient and requires the operator to prepare corresponding protective equipment to reduce the damage caused by the paint to the operator.

[0003] In the production of bathroom cabinets, a paint spraying device is required to spray paint on the surface of the bathroom cabinet. The existing paint spraying device can only spray paint on one side of the bathroom cabinet at a time, which reduces the processing efficiency of the bathroom cabinet. At the same time, when the bathroom cabinet is processed and painted, there is a lack of special clamps for the bathroom cabinet, and the bathroom cabinet cannot be fixed well. If the fixing force is too large, it is easy to crush the furniture, and if the fixing force is too small, the furniture is easy to move and displace during painting, resulting in scratches on the sprayed paint surface, reducing the painting effect and spraying efficiency of the furniture cabinet. Summary of the invention

[0004] In order to make up for the shortcomings of the prior art, the furniture cabinet is limited and fixed in multiple directions in the horizontal and vertical directions, and the area of ​​the fixing points on the furniture cabinet is relatively small to reduce the impact on the spraying effect. The present invention proposes a set of cabinet automatic spraying equipment.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: the complete set of cabinet automatic spraying equipment described in the present invention comprises a frame, a mounting plate is mounted on the frame, a housing is mounted on the mounting plate, a sliding door is arranged on the housing, and a ventilation duct connected to a purification device is installed in the housing;

[0006] A turntable is installed on the mounting plate, and the turntable is driven by a rotating motor, and spraying manipulators are installed at both ends of the housing;

[0007] The sides of the turntable are symmetrically mounted with fixed columns, on which a lifting motor is mounted, and inside the fixed columns a slider is mounted via a screw rod, and the lifting motor drives the screw rod to rotate;

[0008] An electric push rod is installed on the sliding block, a connecting plate is installed on the electric push rod, a thimble is installed on the connecting plate, and the thimble is abutted and fixed on the side of the furniture cabinet.

[0009] Preferably, a telescopic shell is installed on the slider, and the telescopic shell is sleeved on the outside of the electric push rod and the connecting plate. An elastic block is installed on the end of the telescopic shell away from the slider, and the ejector pin passes through the elastic block, and the elastic block does not contact the surface of the furniture cabinet.

[0010] Preferably, an isolation layer is provided on the surface of the elastic block;

[0011] An accommodating cavity is provided inside the elastic block, the ejector pin passes through the accommodating cavity, and the accommodating cavity is filled with paraffin oil.

[0012] Preferably, there is an angle between the ejector pin and the horizontal plane, and the end of the ejector pin away from the slider is tilted downward;

[0013] When the end of the ejector away from the slider abuts against the surface of the furniture cabinet, the slider drives the end of the ejector close to the slider to move downward, so that the end of the ejector close to the slider and the end of the ejector away from the slider are in the same horizontal plane.

[0014] Preferably, one end of the ejector pin away from the slider is sleeved with a plastic layer.

[0015] Preferably, a rubber layer is installed on the surface of the turntable, and evenly distributed limiting needles are installed on the surface of the turntable, and the thickness of the rubber layer is greater than or equal to the height of the limiting needles.

[0016] Preferably, a movable groove is provided on the side of the rubber layer close to the turntable, and the upper end of the limiting needle passes through the movable groove;

[0017] Grooves are arranged on the surface of the rubber layer.

[0018] Preferably, the motor shaft on the rotating motor is connected to the turntable, a connecting ring is installed on the motor shaft, an air pipe is installed on the connecting ring, a connecting hole is opened in the motor shaft, and the movable groove and the connecting ring are connected to each other through the connecting hole;

[0019] The air pipe is connected to an external air source, and an air guide groove is provided on the surface of the limiting needle.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The automatic spraying equipment for a complete cabinet of the present invention is provided with a lifting motor, an electric push rod, a ejector pin, a rubber layer and a limiting pin. The ejector pin is used to limit and fix the furniture cabinet in the horizontal direction. The lifting motor, the ejector pin and the limiting pin are used to increase the longitudinal restriction and fixation on the basis of the horizontal fixation, thereby ensuring that the furniture cabinet will not shake or shift during the spraying process, thereby ensuring a good spraying effect. At the same time, since the diameter of the ejector pin is relatively small, the area of ​​the fixed point left on the surface of the furniture cabinet after spraying is relatively small, and the fixed point left can be conveniently re-sprayed and removed, which is not easy to affect the spraying effect of the furniture cabinet.

[0022] 2. The automatic spraying equipment for a complete cabinet described in the present invention is provided with an elastic block, a accommodating cavity and an isolation layer, so that a layer of paraffin oil will adhere to the surface of the ejector pin when it is extended, thereby reducing the adhesion of the paint contaminated on the surface of the ejector pin, making it easier for the elastic layer to remove the paint adhered to the surface of the ejector pin. At the same time, the paint cleaned off the elastic layer can also be conveniently cleaned under the action of the isolation layer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 6 As shown, the complete set of cabinet automated spraying equipment of the present invention comprises a frame 11, a mounting plate 1 is mounted on the frame 11, a housing 2 is mounted on the mounting plate 1, a sliding door 21 is provided on the housing 2, and a ventilation duct connected to a purification device is installed in the housing 2;

[0033] A turntable 4 is installed on the mounting plate 1, and the turntable 4 is driven by a rotating motor 12. Spraying manipulators 22 are installed at both ends of the housing 2.

[0034] The side of the turntable 4 is symmetrically mounted with a fixed column 3, on which a lifting motor 31 is mounted, and a slider 32 is mounted in the fixed column 3 via a screw rod 311, and the lifting motor 31 drives the screw rod 311 to rotate;

[0035] The slider 32 is provided with an electric push rod 33, the electric push rod 33 is provided with a connecting plate 34, the connecting plate 34 is provided with an ejector pin 35, and the ejector pin 35 is fixedly abutted against the side of the furniture cabinet 5;

[0036] When spraying a set of furniture cabinets 5, the furniture cabinets 5 are placed on the turntable 4, and then the lifting motor 31 and the electric push rod 33 are controlled by the controller: first, the lifting motor 31 is controlled to move, driving the screw rod 311 to rotate, so that the slider 32 drives the electric push rod 33 to gradually move upward until the height of the electric push rod 33 is greater than or equal to half the height of the furniture cabinet 5 to be sprayed, and then the lifting motor 31 is stopped, and then the electric push rod 33 is controlled to gradually extend, driving the connecting plate 34 and the ejector pin 35 to move toward the furniture cabinet 5, so that the end of the ejector pin 35 away from the slider 32 contacts and abuts against the side of the furniture cabinet 5, thereby fixing the furniture cabinet 5 to prevent the furniture cabinet 5 from shaking or displacement during the subsequent spraying process;

[0037] Afterwards, the controller controls the spraying manipulator 22 to start spraying the furniture cabinet 5, and during the spraying process, according to the change of the spraying position, the controller controls the rotating motor 12 to drive the turntable 4 and the furniture cabinet 5 to rotate, so as to facilitate the spraying manipulator 22 to spray the furniture cabinet 5, thereby improving the efficiency and effect of the spraying;

[0038] At the same time, since the diameter of the ejector pin 35 is relatively small, the contact area between the ejector pin 35 and the furniture cabinet 5 is also relatively small. Therefore, when the furniture cabinet 5 is limited and fixed by the ejector pin 35, the unsprayed area remaining on the surface of the furniture cabinet 5 is also relatively small, which reduces the influence of the limitation and fixation of the furniture cabinet 5 on the spraying effect.

[0039] At the same time, after the surface spraying of the furniture cabinet 5 is completed, the controller will control the electric push rod 33 and the lifting motor 31 to return to the initial position, thereby releasing the limit and fixation of the furniture cabinet 5. In this process, when the ejector 35 just begins to leave the furniture cabinet 5, that is, there is a small gap between the ejector 35 and the furniture cabinet 5, and the end of the ejector 35 away from the slider 32 is still located near the furniture cabinet 5, the controller controls the spraying manipulator 22 to spray the small dots formed by the ejector 35 on the furniture cabinet 5, thereby eliminating the adverse effects of the mutual contact between the ejector 35 and the furniture cabinet 5 on the spraying. At the same time, since the ejector 35 is still located near the furniture cabinet 5, in the process of eliminating the small dots formed by the ejector 35 on the furniture cabinet 5, even if the furniture cabinet 5 shakes or moves, it can immediately contact the ejector 35 to stabilize the furniture cabinet 5 to prevent the furniture cabinet 5 from tilting or tipping over;

[0040] At the same time, during the spraying process, some paint will float in the internal space of the housing 2. At this time, the air in the housing 2 will be extracted by the ventilation duct to the external purification device, thereby preventing the paint floating in the spraying process from spreading and affecting the health of the workers;

[0041] At the same time, a pipe connected to a hot air blower is also installed in the casing 2. Before the furniture cabinet 5 is fixed and spraying begins, hot air is sent into the casing 2 through the hot air blower to preheat the surface of the furniture cabinet 5 and increase the surface temperature of the furniture cabinet 5, so as to avoid excessive temperature difference between the surface of the furniture cabinet 5 and the sprayed paint during the spraying process, which will affect the subsequent paint spraying effect on the furniture cabinet 5.

[0042] As an embodiment of the present invention, a telescopic shell 331 is installed on the slider 32, and the telescopic shell 331 is sleeved on the outside of the electric push rod 33 and the connecting plate 34. An elastic block 36 is installed at one end of the telescopic shell 331 away from the slider 32, and the ejector pin 35 passes through the elastic block 36, and the elastic block 36 does not contact the surface of the furniture cabinet 5;

[0043] When the electric push rod 33 begins to extend, the connecting plate 34 located in the telescopic shell 331 will drive the telescopic shell 331 to extend together. When the telescopic shell 331 is fully extended, the connecting plate 34 will continue to extend for a distance, so that the ejector pin 35 on the connecting plate 34 passes through the elastic block 36 at the end of the telescopic shell 331 away from the slider 32. At this time, there is a gap between the elastic block 36 and the furniture cabinet 5, which can facilitate the spraying manipulator 22 to spray the surface of the furniture cabinet 5, and avoid the elastic block 36 contacting the furniture cabinet 5 or the distance between the elastic block 36 and the furniture cabinet 5 is too close, which will interfere with the spraying manipulator 22, resulting in a spraying dead angle on the surface of the furniture cabinet 5, affecting the spraying effect;

[0044] At the same time, since the ejector pin 35 limits and fixes the furniture cabinet 5, when paint is sprayed on the surface of the furniture cabinet 5, a part of the paint will also be stained on the surface of the ejector pin 35. The ejector pin 35 passes through the elastic block 36. When the spraying of the furniture cabinet 5 is completed and the electric push rod 33 is retracted, the connecting plate 34 and the ejector pin 35 will first drive the telescopic shell 331 and the elastic block 36 to be retracted together. When the telescopic shell 331 is fully retracted, the connecting plate 34 will continue to drive the ejector pin 35 to be retracted, so that the ejector pin 35 is withdrawn from the elastic block 36, so that the paint stained on the surface of the ejector pin 35 is wiped and scraped by the elastic block 36, and the paint stained on the surface of the ejector pin 35 is removed as much as possible to ensure the cleanliness of the surface of the ejector pin 35 and avoid affecting the subsequent spraying effect of the furniture cabinet 5.

[0045] As an embodiment of the present invention, an isolation layer 361 is provided on the surface of the elastic block 36;

[0046] The elastic block 36 has an accommodating cavity 362 formed inside, and the ejector pin 35 passes through the accommodating cavity 362 . The accommodating cavity 362 is filled with paraffin oil.

[0047] By providing an isolation layer 361 composed of wax or tape on the surface of the elastic block 36, the paint wiped or scraped off by the ejector pin 35 by the elastic block 36 will not be firmly attached to the surface of the elastic block 36, so that the paint attached to the surface of the elastic block 36 can be easily cleaned;

[0048] At the same time, when the ejector pin 35 passes through the elastic block 36, the ejector pin 35 will pass through the paraffin oil in the accommodating cavity 362, so that a layer of paraffin oil film will exist on the surface of the ejector pin 35 extending out of the elastic block 36, so that the paint contaminated on the surface of the ejector pin 35 during the spraying process of the furniture cabinet 5 will not adhere firmly, so that when the ejector pin 35 is retracted from the elastic block 36, the elastic block 36 will remove the paint adhering to the surface of the ejector pin 35.

[0049] As an embodiment of the present invention, there is an angle between the ejector pin 35 and the horizontal plane, and the end of the ejector pin 35 away from the slider 32 is tilted downward;

[0050] When the end of the ejector pin 35 away from the slider 32 abuts against the surface of the furniture cabinet 5, the slider 32 drives the end of the ejector pin 35 close to the slider 32 to move downward, so that the end of the ejector pin 35 close to the slider 32 and the end of the ejector pin 35 away from the slider 32 are in the same horizontal plane;

[0051] Through the data fed back to the controller by the sensor on the electric push rod 33, the controller can accurately determine the moment when the ejector pin 35 abuts against the furniture cabinet 5 to limit and fix the furniture cabinet 5. After that, the controller will control the lifting motor 31 to drive the slider 32 to move downward by one end, so that the inclined ejector pin 35 becomes horizontal again or the end of the ejector pin 35 close to the slider 32 is tilted downward, so as to utilize the elasticity of the ejector pin 35 to apply additional downward force to the furniture cabinet 5, ensure that the bottom surface of the furniture cabinet 5 can be tightly attached to the turntable 4, ensure the good effect of limiting and fixing the furniture cabinet 5, and avoid shaking or displacement of the furniture cabinet 5 during the spraying process, which affects the spraying effect.

[0052] As an embodiment of the present invention, one end of the ejector pin 35 away from the slider 32 is sleeved with a plastic layer;

[0053] By sleeved a plastic layer on the ejector pin 35, the position where the ejector pin 35 and the furniture cabinet 5 contact each other is made relatively soft, thereby avoiding that the contact position of the ejector pin 35 and the furniture cabinet 5 exerts a large pressure on the furniture cabinet 5, causing the metal ejector pin 35 to damage the surface of the furniture cabinet 5 under the action of pressure.

[0054] As an embodiment of the present invention, a rubber layer 41 is installed on the surface of the turntable 4, and uniformly distributed limiting needles 42 are installed on the surface of the turntable 4, and the thickness of the rubber layer 41 is greater than or equal to the height of the limiting needles 42;

[0055] By arranging a rubber layer 41 on the turntable 4, the process of placing the furniture cabinet 5 on the turntable 4 is buffered to prevent the bottom edge of the furniture cabinet 5 from colliding with the turntable 4 and being damaged. At the same time, after the furniture cabinet 5 is placed on the turntable 4, due to the gravity of the furniture cabinet 5, the furniture cabinet 5 will squeeze and compress the rubber layer 41, so that the thickness of the rubber in the compressed part is smaller than the height of the limiting needle 42. At this time, the bottom surface of the furniture cabinet 5 and the limiting needle 42 will contact and abut each other, further limiting and fixing the position of the furniture cabinet 5, preventing the furniture cabinet 5 from shaking or displacing during the spraying process, thereby ensuring the spraying quality and spraying effect.

[0056] As an embodiment of the present invention, a movable groove 411 is formed on the side of the rubber layer 41 close to the turntable 4, and the upper end of the limiting needle 42 passes through the movable groove 411;

[0057] A groove 412 is formed on the surface of the rubber layer 41;

[0058] By providing the movable groove 411 on the rubber layer 41, the force required for the rubber layer 41 to be deformed by pressure is reduced, and when the furniture cabinet 5 with relatively small size or light weight is sprayed, the furniture cabinet 5 can also squeeze the rubber layer 41, so that the limiting needle 42 limits and fixes the bottom surface of the furniture cabinet 5, thereby preventing the furniture cabinet 5 from shaking or displacement during the spraying process;

[0059] At the same time, since the surface of the rubber layer 41 is provided with a groove 412, when the furniture cabinet 5 squeezes the rubber layer 41 and causes the rubber layer 41 to deform, the portion of the rubber layer 41 close to the furniture cabinet 5 will be concave and deformed downward. In this process, the edge of the bottom surface of the furniture cabinet 5 is likely to sink into the groove 412, thereby further limiting and fixing the furniture cabinet 5 on the rubber layer 41 to prevent the furniture cabinet 5 from displacement and shaking.

[0060] As an embodiment of the present invention, the motor shaft 121 on the rotating motor 12 is connected to the turntable 4, a connecting ring 131 is installed on the motor shaft 121, an air pipe 13 is installed on the connecting ring 131, a connecting hole 122 is opened in the motor shaft 121, and the movable groove 411 and the connecting ring 131 are connected to each other through the connecting hole 122;

[0061] The air pipe 13 is connected to an external air source, and an air guide groove is provided on the surface of the limiting needle 42;

[0062] When placing the furniture cabinet 5, the movable groove 411 is evacuated by an external air source, so that the movable groove 411 is in a negative pressure state, thereby promoting the rubber layer 41 to deform, and the furniture cabinet 5 contacts the limiting needle 42 and is limited and fixed;

[0063] At the same time, when the spraying of the furniture cabinet 5 is completed, the limiting and fixing of the furniture cabinet 5 by the ejector pin 35 is first released, and then the movable groove 411 is inflated through an external air source, so that the pressure in the movable groove 411 is too large and the rubber layer 41 expands, which promotes the bottom surface of the furniture cabinet 5 to break away from the contact of the limiting needle 42, making it convenient to remove the furniture cabinet 5 from the turntable 4. At the same time, when the movable groove 411 is inflated, part of the gas in the movable groove 411 will be discharged from the air guide groove on the limiting needle 42, and further blow air between the bottom surface of the furniture cabinet 5 and the rubber layer 41, so as to avoid negative pressure between the bottom surface of the furniture cabinet 5 and the rubber layer 41, and avoid affecting the removal of the furniture cabinet 5 from the turntable 4.

[0064] The specific workflow is as follows:

[0065] When spraying a set of furniture cabinets 5, the furniture cabinets 5 are placed on the turntable 4, and then the lifting motor 31 and the electric push rod 33 are controlled by the controller: first, the lifting motor 31 is controlled to move, driving the screw rod 311 to rotate, so that the slider 32 drives the electric push rod 33 to gradually move upward until the height of the electric push rod 33 is greater than or equal to half the height of the furniture cabinet 5 to be sprayed, and then the lifting motor 31 is stopped, and then the electric push rod 33 is controlled to gradually extend, driving the connecting plate 34 and the ejector pin 35 to move toward the furniture cabinet 5, so that the ejector pin 35 is far in contact with and abuts against the side of the furniture cabinet 5 to fix the furniture cabinet 5;

[0066] Afterwards, the controller controls the spraying robot 22 to start spraying the furniture cabinet 5, and the controller controls the rotating motor 12 to drive the turntable 4 and the furniture cabinet 5 to rotate;

[0067] At the same time, after the surface spraying of the furniture cabinet 5 is completed, the controller will control the electric push rod 33 and the lifting motor 31 to return to the initial position, and release the limit and fixation of the furniture cabinet 5. In this process, when the ejector 35 just begins to leave the furniture cabinet 5, that is, there is a small gap between the ejector 35 and the furniture cabinet 5, and the end of the ejector 35 away from the slider 32 is still located near the furniture cabinet 5, the controller controls the spraying manipulator 22 to spray the small dots formed by the ejector 35 on the furniture cabinet 5, so as to eliminate the adverse effects of the mutual contact between the ejector 35 and the furniture cabinet 5 on the spraying. At the same time, since the ejector 35 is still located near the furniture cabinet 5, in the process of eliminating the small dots formed by the ejector 35 on the furniture cabinet 5, even if the furniture cabinet 5 shakes or moves, it can immediately contact the ejector 35 to stabilize the furniture cabinet 5;

[0068] At the same time, during the spraying process, some paint will float in the internal space of the housing 2. At this time, the air in the housing 2 will be extracted by the ventilation duct to the external purification device to prevent the paint floating in the spraying process from spreading;

[0069] At the same time, a pipe connected to a hot air blower is also installed in the housing 2. Before the furniture cabinet 5 is fixed and spraying begins, hot air is sent into the housing 2 through the hot air blower to preheat the surface of the furniture cabinet 5 and increase the surface temperature of the furniture cabinet 5;

[0070] When the electric push rod 33 begins to extend, the connecting plate 34 located in the telescopic shell 331 will drive the telescopic shell 331 to extend together. When the telescopic shell 331 is fully extended, the connecting plate 34 will continue to extend for a distance, so that the ejector pin 35 on the connecting plate 34 passes through the elastic block 36 at the end of the telescopic shell 331 away from the slider 32. At this time, there is a gap between the elastic block 36 and the furniture cabinet 5, which is convenient for the spraying robot 22 to spray the surface of the furniture cabinet 5.

[0071] At the same time, when the spraying of the furniture cabinet 5 is completed and the electric push rod 33 is retracted, the connecting plate 34 and the ejector pin 35 will first drive the telescopic shell 331 and the elastic block 36 to be retracted together. When the telescopic shell 331 is completely retracted, the connecting plate 34 will continue to drive the ejector pin 35 to be retracted, so that the ejector pin 35 is withdrawn from the elastic block 36, so that the paint on the surface of the ejector pin 35 is wiped and scraped by the elastic block 36, and the paint on the surface of the ejector pin 35 is removed as much as possible;

[0072] By providing an isolation layer 361 composed of wax or tape on the surface of the elastic block 36, the paint wiped or scraped off by the ejector pin 35 by the elastic block 36 will not be firmly attached to the surface of the elastic block 36, so that the paint attached to the surface of the elastic block 36 can be easily cleaned;

[0073] At the same time, when the ejector pin 35 passes through the elastic block 36, the ejector pin 35 will pass through the paraffin oil in the accommodating cavity 362, so that a layer of paraffin oil film exists on the surface of the ejector pin 35 extending out of the elastic block 36, so that the paint contaminated on the surface of the ejector pin 35 during the spraying process of the furniture cabinet 5 is not firmly attached;

[0074] The controller can accurately determine the moment when the ejector pin 35 abuts against the furniture cabinet 5 and limits and fixes the furniture cabinet 5 through the data fed back by the sensor on the electric push rod 33. After that, the controller will control the lifting motor 31 to drive the slider 32 to move downward by an end distance, so that the inclined ejector pin 35 becomes horizontal again or the end of the ejector pin 35 close to the slider 32 tilts downward, so as to utilize the elasticity of the ejector pin 35 to apply an additional downward force to the furniture cabinet 5.

[0075] By sleeve-fitting the plastic layer on the ejector pin 35, the contact position between the ejector pin 35 and the furniture cabinet 5 is relatively soft, so as to avoid that the contact position between the ejector pin 35 and the furniture cabinet 5 exerts a large pressure on the furniture cabinet 5, causing the metal ejector pin 35 to damage the surface of the furniture cabinet 5 under the pressure;

[0076] By arranging the rubber layer 41 on the turntable 4, the process of placing the furniture cabinet 5 on the turntable 4 is buffered. At the same time, after the furniture cabinet 5 is placed on the turntable 4, due to the gravity of the furniture cabinet 5, the furniture cabinet 5 will squeeze and compress the rubber layer 41, so that the thickness of the rubber in the compressed part is smaller than the height of the limiting needle 42. At this time, the bottom surface of the furniture cabinet 5 and the limiting needle 42 will contact and abut each other, further limiting and fixing the position of the furniture cabinet 5.

[0077] By providing the movable groove 411 on the rubber layer 41, the force required for the rubber layer 41 to be deformed under pressure is reduced, and thus when spraying a relatively small or light furniture cabinet 5, the furniture cabinet 5 can also squeeze the rubber layer 41, so that the limiting needle 42 limits and fixes the bottom surface of the furniture cabinet 5;

[0078] At the same time, since the surface of the rubber layer 41 is provided with a groove 412, when the furniture cabinet 5 squeezes the rubber layer 41 and deforms the rubber layer 41, the portion of the rubber layer 41 close to the furniture cabinet 5 will be deformed downward. In this process, the edge of the upper bottom surface of the furniture cabinet 5 is easily sunken into the groove 412, further limiting and fixing the furniture cabinet 5 on the rubber layer 41 to prevent the furniture cabinet 5 from displacement and shaking.

[0079] When placing the furniture cabinet 5, the movable groove 411 is evacuated by an external air source, so that the movable groove 411 is in a negative pressure state, thereby promoting the rubber layer 41 to deform, and the furniture cabinet 5 contacts the limiting needle 42 and is limited and fixed;

[0080] At the same time, when the spraying of the furniture cabinet 5 is completed, the limiting and fixing of the furniture cabinet 5 by the ejector pin 35 is first released, and then the movable groove 411 is inflated through an external air source, so that the pressure in the movable groove 411 is too large and the rubber layer 41 expands, which promotes the bottom surface of the furniture cabinet 5 to break away from the contact of the limiting needle 42, making it convenient to remove the furniture cabinet 5 from the turntable 4. At the same time, when the movable groove 411 is inflated, part of the gas in the movable groove 411 will be discharged from the air guide groove on the limiting needle 42, and further blow air between the bottom surface of the furniture cabinet 5 and the rubber layer 41, so as to avoid negative pressure between the bottom surface of the furniture cabinet 5 and the rubber layer 41, and avoid affecting the removal of the furniture cabinet 5 from the turntable 4.
