Description

Technical Field

[0001] The invention relates to the technical field of plate spraying, in particular to a furniture plate spraying system. Background Art

[0002] At present, the main component of the automated furniture panel spraying production line is the hanging rail mechanism. Since the panel spraying process is divided into multiple steps, such as spraying, curing, and drying, in order to achieve automated processing, the hanging rail mechanism is required to drive the panel to circulate at multiple stations, so that the panel can be processed through multiple processes to obtain the finished panel with coating.

[0003] The key problem with hanging rails is that they cannot be fixed using a clamping mechanism. The advantage of the clamping mechanism is that it is suitable for clamping most plates, but the clamping surface covers the surface of the plate during clamping, which will cause obstruction in the spraying step, resulting in abnormalities in the finished plate and the need to add a touch-up paint step.

[0004] There is a plug-in hole on the side of the plate, and the head of the plug-in screw enters into the screw lock hole through the plug-in hole. A screw lock buckle with a single-side opening is provided in the screw lock hole. The screw lock buckle is rotated to lock with the screw head. The screw lock hole and the plug-in hole are easily adhered with topcoat during the painting process, which can easily cause the inner diameter of the hole to change. For multiple coating processes, it is easy to cause the hole to be filled too thickly, affecting the subsequent installation and connection. Summary of the invention

[0005] The purpose of the present invention is to provide a furniture panel spraying system, which realizes dynamic hanging with plug-in holes and screw-lock holes as the core. During the processing, not only can the direction be switched to meet the adjustment requirements of multiple process processing, but the shielding surface can also be adjusted to avoid paint obstruction at the hanging place to achieve comprehensive painting, and the plug-in holes and screw-lock holes can be sealed and protected to avoid secondary hole repair to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 6 : In this embodiment: it includes a hanging rail module 100 that limits the motion trajectory of the self-propelled module 300. The self-propelled module 300 fixes the workpiece through the cross-rail module 400, so that the workpiece moves according to the distribution path of the spray module 200. There are two connecting modules 500 slidingly connected below the cross-rail module 400, and the connecting modules 500 are respectively connected to the splicing side walls of the plate body.

[0027] In the present embodiment: the self-propelled module 300 moves according to the layout track of the hanging rail module 100 in the factory. In order to increase the hanging points to accommodate plates of various specifications, a cross-rail module 400 is provided. The connecting module 500 is connected to the cross-rail module 400. The connecting module 500 can slide on the cross-rail module 400. The connecting module 500 is connected to the side wall of the plate, so it can be adjusted according to the position of the plate when sliding on the cross-rail module 400.

[0028] In this embodiment: the cross rail module 400 includes a positioning cross rail 401 and a fixed column 402, the self-propelled module 300 includes a rotating unit 301 and a track self-propelled unit 302, the rotating unit 301 drives the track self-propelled unit 302 to slide in the hanging rail module 100, and the rotating unit 301 controls the rotation of the positioning cross rail 401 through the fixed column 402.

[0029] In this embodiment: although the hanging rail module 100 has an arc track, which can realize the rotation of the plate, different process steps are different. The advantage of setting the rotating unit 301 is that the fixed column 402 can be controlled to rotate by the rotating unit 301 according to the needs at the straight track, so that the angle of the positioning cross rail 401 changes. The track self-propelled unit 302 is a driving wheel assembly, which controls the movement of the motor through electricity, and the motor drives the driving wheel to rotate, so that the driving wheel can move in the hanging rail module 100.

[0030] In this embodiment: the connection module 500 includes a hanger plate posture control connector 1, two traction ropes 2, and two rotary lock plate hole connectors 3. The hanger plate posture control connector 1 includes a transverse self-propelled unit 11 and two winding units 12. The transverse self-propelled unit 11 slides in the positioning cross rail 401. The two winding units 12 respectively wind up the two traction ropes 2. The rotary lock plate hole connector 3 is connected to the end of the traction rope 2. The rotary lock plate hole connector 3 is inserted from the board body plug-in hole and realizes self-locking in the rotary lock hole.

[0031] In this embodiment: the hanging board attitude control connector 1 and the positioning rail 401 are slidable, and the lateral self-propelled unit 11 slides on the positioning rail 401, so that the lateral self-propelled unit 11 can drive the winding unit 12 to move. The winding unit 12 is composed of a servo motor, a controller, and a winding roller. The controller controls the servo motor to rotate forward or reverse at a certain time period and a certain position. The number of plug-in holes on one side of the conventional plate body is at least two, so the number set in the present invention is two. If there are too many holes in the plate body, it means that the plate body is heavy, so three, four or more holes can be set. Under the action of the two-point type, it is only necessary to control the winding or release length of the traction rope 2 to control the tilt of the plate body. The process that satisfies the tilt is: spraying the corners of the concave and convex surfaces of the plate, spraying the unobstructed side walls of the plate, and spraying the back of the plate. And although the connecting side of the plate is blocked by the traction rope 2, during the spraying process of the plate side, since the plate can be rotated, the blocking surface of the traction rope 2 and the connecting side is constantly changing, so full spraying can still be achieved.

[0032] In this embodiment: the plug holes equipped on the plate body are used as the center, the plug holes are connected, and the position and angle of the plate body are changed by means of multi-rope traction control, so as to meet the requirements of corner spraying, shielding surface spraying, and changing surface spraying.

[0033] In this embodiment: the rotary lock plate hole connector 3 includes an extension connecting tube 31, a control screw 32, and a rubber jacket 33. The rubber jacket 33 is fixedly connected to the circumferential side of the extension connecting tube 31, and the outer wall surface of the rubber jacket 33 contacts the inner wall of the plug-in hole. The external part of the extension connecting tube 31 is rotatably connected to a rope fixing slip ring 38, and the rope fixing slip ring 38 is fixedly connected to the traction rope 2. The control screw 32 is rotatably connected to the inner hole of the extension connecting tube 31, and the control screw 32 extends into the rotary lock hole.

[0034] In this embodiment: first, the extension connecting tube 31 is the basic pipeline, and the rubber jacket 33 is sleeved on the outside of the extension connecting tube 31. The rubber jacket 33 can contact the hole body when the extension connecting tube 31 enters the plug-in hole to avoid self-rotation. At this time, the control screw 32 is exposed to the outside of the extension connecting tube 31 for controlling the rotation. The traction rope 2 is connected to the fixed rope slip ring 38. When the traction rope 2 controls the plate body to move, the fixed rope slip ring 38 can rotate relative to the extension connecting tube 31, so that the extension connecting tube 31 will not rotate.

[0035] In this embodiment: the end of the control screw 32 is rotatably connected with a support ball 37, and the support ball 37 contacts the inner wall of the rotary lock hole. The support ball 37 contacts the rotary lock hole, and the circular structure is used to avoid damage to the rotary lock hole. The support ball 37 can also be made of rubber material to play a buffering role on the rotary lock hole. The ball structure of the support ball 37 can be replaced according to demand.

[0036] In this embodiment: one end of the peripheral side of the control screw 32 close to the support ball 37 is a smooth surface, and the smooth surface is rotatably connected to the limit slip ring 34, and the support slip ring 35 is threadedly connected to the threaded surface of the control screw 32. The end of the extended connecting tube 31 slides and limits the limit slip ring 34 and the support slip ring 35 through the guide rod 311. The peripheral side of the limit slip ring 34 is rotatably connected to at least two symmetrically distributed limit rods 341 through a torsion spring, and the support slip ring 35 is fixedly connected to a support rod 351 corresponding to the limit rod 341 and in contact with each other.

[0037] In this embodiment: in the insertion stage, the limit rod 341 is in close contact with the support rod 351 under the influence of the torsion spring. At this time, the shape is conical, and the distance between the two limit rods 341 is not greater than the diameter of the rubber sleeve 33. In this stage, the control screw 32 can drive the limit slip ring 34 into the rotary lock hole. The circular shape is the rotary lock hole. At this time, the support ball 37 is in contact with the rotary lock hole, so that the extension connecting tube 31 cannot move further to the left. At this time, the control screw 32 is rotated, and the support slip ring 35 is limited by the guide rod 311, and the limit slip ring 34 is limited by the guide rod 311, so that the support slip ring 35 can only slide toward the limit slip ring 34, and the support rod 351 keeps in contact with the limit rod 341 and makes the limit rod 341 expand to both sides under the influence of pushing, so as to contact with the side wall of the rotary lock hole, please refer to 7. In this state, the extension connecting tube 31 slides to the right side and cannot move due to the contact of the limit rod 341. At the same time, the extension connecting tube 31 cannot move to the left side, thereby realizing the connection with the rotary lock hole.

[0038] In this embodiment: the end of the extension connecting tube 31 is fixedly connected with a closing sleeve 36 that surrounds the limit slip ring 34 and the support slip ring 35. An air intake pipe is opened outside the extension connecting tube 31. After the limit rod 341, the support rod 351 and the rotary lock hole are supported and fixed, the closing sleeve 36 is inflated so that the closing sleeve 36 covers the rotary lock hole.

[0039] In this embodiment: although the limit rod 341 can be limited with the rotary lock hole, it cannot achieve the closure of the rotary lock hole, and in the paint spraying environment, the internal structure of the limit rod 341 will also be affected by the paint spraying, resulting in difficulty in movement, so a closed sleeve 36 is provided, and since an air intake pipe is provided outside the extension connecting pipe 31, gas can be rushed into the closed sleeve 36, and the gas expands the closed sleeve 36, and a dynamic sealing structure is provided between the rotation part of the extension connecting pipe 31 and the control screw 32 to achieve sealing, and the air intake pipe can be blocked by a plug. At this time, the closed sleeve 36 covers the rotary hole groove, so that the paint spraying cannot act on the groove body.

[0040] In this embodiment: the lateral self-propelled unit 11 is provided with a self-locking mechanism that cooperates with the positioning rail 401. After the hanging board attitude control connector 1 adjusts its position, it is locked with the positioning rail 401 through the self-locking mechanism, so that the traction rope 2 remains vertical, and is connected to the board body through the rotating locking plate hole connector 3.

[0041] In this embodiment, the length of the extension connecting tube 31 located at the bottom is greater than the length of the extension connecting tube 31 located at the top, and the two traction ropes 2 on the same side are distributed in parallel.

[0042] In this embodiment: when the length of the extension connecting tube 31 located below is greater than the length of the extension connecting tube 31 located above, the plate body will not cause interference when the rotation angle is less than 360 degrees. If it is necessary to rotate 360 ​​degrees, it is necessary to further release the length of the traction rope 2 below, so that the traction rope 2 located on the inner side below is in a free bending state, and the traction rope 2 above is stressed and in a straight state, thereby meeting the 360-degree rotation requirement. It can also be rotated 360 degrees with the help of the fixed column 402. In order to avoid the horizontal space interference problem caused by the rotation of the fixed column 402, the two lateral self-propelled units 11 are synchronously translated on the positioning guide rail 401 when the gravity eccentricity does not affect the fixed column 402. When the fixed column 402 is driven to rotate, the distance between the plate body and the nozzle is increased to avoid structural interference.

[0043] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
