Description

Technical Field

[0001] The present invention relates to the technical field of lifting table painting, and more specifically, to a partitioned panel painting device for an automatic lifting table and its working method. Background Art

[0002] An electric lifting table is a table that can adjust the height of the tabletop through electric control. Its core function is to allow users to freely switch between sitting and standing postures to reduce the adverse effects of prolonged sitting on the body. Generally, it consists of a lifting device, a control system, a tabletop, a table frame, table legs, and a power supply system. Among them, the tabletop is the load-bearing part of the electric lifting table and is used to place items.

[0003] In the prior art, the production of the tabletop first requires selecting suitable raw materials, and then using professional cutting equipment to cut the board into the required size and shape. At the same time, operations such as grooving and drilling are performed on the board to reserve holes for subsequent installation. Then, edge sealing treatment is carried out on the board. Finally, the surface of the board is polished to make it smooth and flat. At the same time, surface decoration such as sticker pasting, painting, or solid wood veneer pasting is carried out according to design requirements.

[0004] However, most of the existing painting equipment uses spray guns to perform large-area painting on the surface of the board without any partitioned painting treatment. If the tabletop is composed of two regular boards spliced together, it will cause the painting equipment to repeatedly paint the gap at the splicing of the two boards, resulting in visible "step" - shaped marks at the splicing of the two boards, thus reducing the painting effect of the tabletop and being unfavorable to the production quality of the tabletop.

[0005] Therefore, a partitioned panel painting device for an automatic lifting table and its working method are proposed to improve the existing problems. Summary of the Invention

[0016] A partitioned panel painting method for an automatic lifting table, using the partitioned panel painting device for an automatic lifting table as described above, includes the following steps: S1. First, the staff place the spliced plates on the painting unit. Then, the painting unit is started. It first moves to above one of the plates and then performs the painting process. At this time, the deformation unit is located above the gap between the spliced plates, only exposing the surface of one of the plates and the gap, covering the surface of the other plate close to the gap without interfering with the painting process. S2. During the working process of S1, if the two plates are regular, the gaps between the two plates are on the same horizontal line. At this time, only the initial state of the deformation unit is needed to cover the surface of the unpainted plate close to the gap. At the same time, during the painting process along the gap, on the one hand, the corresponding electric slide rail is started to drive the corresponding micro brush to slide synchronously. The micro brush rolls on the surface of the unpainted plate, so that the micro brush is evenly distributed flush with the painting point of the painting unit, avoiding the painting unit from painting the paint on the surface of the unpainted plate. On the other hand, the adjustment motor is started, and its output end drives the adjustment shaft and the micro brush to rotate synchronously, so that the rolling direction of the micro brush is consistent with the direction of the gap. S3. After the surface and gap of one of the plates are painted, the deformation unit is moved to above the painted plate to cover both the position of the painted plate close to the gap and the gap at the same time. At this time, the micro brush needs to be wetted with paint so that the micro brush rolls on the surface of the painted plate, preventing the paint from overlapping at the gap. S4. If the tabletop is composed of two irregular but regular plates spliced together, the deformation motor is started to drive the movable bar to rotate, so that the movable bar can slide in the movable plate and drive the movable plate to swing left and right, so that the main connecting plate and the deformation gear swing left and right synchronously, and then the deformable part deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular plates, achieving the purpose of covering the gaps between the two irregular but regular plates. S5. During the working process of S4, on the one hand, the corresponding electric slide rail is started to drive the corresponding micro brush to slide synchronously. The micro brush rolls on the surface of the unpainted plate, so that the micro brush is evenly distributed flush with the painting point of the painting unit, avoiding the painting unit from painting the paint on the surface of the unpainted plate. At this time, the micro brush should roll along the corresponding gap direction. On the other hand, the adjustment motor is started, and its output end drives the adjustment shaft and the micro brush to rotate synchronously, so that the rolling direction of the micro brush is consistent with the direction of the gap.

[0017] In summary, the present application includes at least one of the following beneficial technical effects: (1) Through the design of the deformation unit, it can not only block the gaps between two regular plates, but also block the gaps between two irregular but regular plates, thus avoiding the problem that the painting equipment repeatedly paints the gaps at the joint of the two plates, making the "step" - shaped marks visible at the joint of the two plates, improving the painting effect of the tabletop, and further improving the production quality of the tabletop.

[0018] (2) Through the design of the shielding unit, it can shield both the painted plate and the gap at the same time. While shielding, on the one hand, it does not damage the original painted surface, and on the other hand, it can perform supplementary painting on the positions where the surfaces of the plates on both sides of the gap are missed due to the design of the deformation unit itself, thus ensuring the spraying quality of the tabletop and further improving the spraying efficiency of the tabletop.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0029] Among them, the role of the deformation unit 2 is to block the gaps between two regular plates and also to block the gaps between two irregular but regular plates, thereby avoiding the problem that the painting equipment repeatedly paints the gaps at the joint of the two plates, making the "step"-shaped traces visible at the joint of the two plates, thereby improving the painting effect of the tabletop and further improving the production quality of the tabletop.

[0030] The role of the occlusion unit 3 is to simultaneously block and process the painted plate and the gap. While blocking, on the one hand, it does not damage the original painted surface, and on the other hand, it can perform supplementary leak painting treatment on the positions where the surfaces of the plates on both sides of the gap are missed due to the design of the deformation unit 2 itself, thereby ensuring the spraying quality of the tabletop and further improving the spraying efficiency of the tabletop.

[0031] Refer to Figures 1-2 , specifically, the painting unit 1 includes a workbench 11, Y-axis horizontal electric linear guides 12 symmetrically arranged in the radial N direction on the top of the workbench 11, a painting table 13 arranged between the Y-axis horizontal electric linear guides 12, an X-axis horizontal electric linear guide 14 arranged above the painting table 13, a vertical electric linear guide 15 arranged on one side of the X-axis horizontal electric linear guide 14, and a painting member 16 arranged on the side of the vertical electric linear guide 15 away from the X-axis horizontal electric linear guide 14.

[0032] Among them, starting through the Y-axis horizontal electric linear guide rail 12, the painting table 13 and the splicing table board placed on the surface of the painting table 13 can be displaced synchronously and displaced below the X-axis horizontal electric linear guide rail 14; subsequently, the X-axis horizontal electric linear guide rail 14 starts, driving the vertical electric linear guide rail 15 and the painting member 16 to be displaced above the plate to be painted. At the same time, the vertical electric linear guide rail 15 starts, driving the painting member 16 to approach the surface of the plate for painting treatment.

[0033] Refer to Figures 3-6 , specifically, the deformation unit 2 includes a deformation motor 21, a movable bar 22 arranged at the output end of the deformation motor 21, a movable plate 23 arranged at one end of the movable bar 22 away from the deformation motor 21, a main connecting plate 24 arranged at one end of the movable plate 23 away from the movable bar 22, a deformation gear 25 arranged at one end of the main connecting plate 24 away from the movable plate 23, a deformation member 26 meshing and driving with the deformation gear 25, and an auxiliary member 27 arranged above the deformation member 26.

[0034] Among them, if the table board is spliced by two irregular but regular plates, the deformation motor 21 starts, driving the movable bar 22 to rotate, so that the movable bar 22 can slide in the movable plate 23 and drive the movable plate 23 to swing left and right, so that the main connecting plate 24 and the deformation gear 25 swing left and right synchronously, and then the deformation member 26 deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular plates, achieving the purpose of covering the gaps between the two irregular but regular plates; avoiding the problem that the painting equipment repeatedly paints the gaps at the splicing place of the two plates, making the visible "step" - shaped traces at the splicing place of the two plates, thus improving the painting effect of the table board and further improving the production quality of the table board.

[0035] Refer to Figures 1-2 , further, the painting member 16 includes a first support plate 161, a first motor 162 arranged at the top of the first support plate 161, a second support plate 163 arranged at the output end of the first motor 162, a second motor 164 arranged on one side of the second support plate 163, and a painting gun 165 arranged at the output end of the second motor 164; the side wall of the first support plate 161 is connected to the side of the vertical electric linear guide rail 15 away from the X-axis horizontal electric linear guide rail 14, and the output end of the second motor 164 penetrates the side wall of the second support plate 163 and is connected to the outer wall of the painting gun 165.

[0036] Among them, when the first motor 162 starts, driving the second support plate 163 to rotate, and at the same time the second motor 164 starts, driving the painting gun 165 to rotate, the purpose of adjusting the painting angle of the painting gun 165 is achieved, which is beneficial to the uniformity of painting.

[0037] Refer to Figure 3, Further, an arc-shaped slide rail 131 is provided on the top of the painting table 13, and an arc-shaped block 132 is slidably arranged on the arc-shaped slide rail 131; a column 133 is provided on the top of the arc-shaped block 132, and the output end of the deformation motor 21 penetrates through the side wall of the column 133 and is connected to one end of the movable bar 22 away from the movable plate 23. A ring plate 134 is further provided on one side of the column 133, and a through groove 135 is opened on the side wall of the ring plate 134 away from the column 133.

[0038] Among them, if the tabletop is spliced by two irregular but regular plates, when the deformation motor 21 is started, it drives the movable bar 22 to rotate, so that the movable bar 22 can slide in the movable plate 23, and drives the connection between the movable plate 23 and the main connecting plate 24 to swing left and right in the through groove 135, so that the main connecting plate 24 and the deformation gear 25 swing left and right synchronously, and further the deformation part 26 deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular plates, achieving the purpose of covering the gaps between the two irregular but regular plates.

[0039] During this process, the ring plate 134 will also drive the column 133 to swing left and right in the reverse direction, so that the column 133 drives the arc-shaped block 132 to slide on the arc-shaped slide rail 131, thus achieving the purpose of guiding.

[0040] Refer to Figures 4-6 , Further, the movable bar 22 is in an irregular shape, and a movable pin 221 is provided at one end of the movable bar 22 away from the deformation motor 21. The movable plate 23 is in a T shape, and a movable groove 231 is opened on the side wall of the movable plate 23 close to the movable bar 22. The movable pin 221 can cooperate and slide in the movable groove 231; both the movable bar 22 and the movable plate 23 are located within the ring plate 134. One end of the movable plate 23 away from the movable groove 231 penetrates through the through groove 135 and is connected to one end of the main connecting plate 24 away from the deformation gear 25, and the connection between the movable plate 23 and the main connecting plate 24 can be rotatably connected to the inner wall of the through groove 135.

[0041] Among them, when the deformation motor 21 is started, it drives the movable bar 22 to rotate, so that the movable pin 221 can slide in the movable groove 231, and drives the movable plate 23 to swing left and right, so that the main connecting plate 24 and the deformation gear 25 swing left and right synchronously, and further the deformation part 26 deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular plates, achieving the purpose of covering the gaps between the two irregular but regular plates; avoiding the problem that the painting equipment repeatedly paints the gaps at the splicing place of the two plates, resulting in visible "step" - shaped traces at the splicing place of the two plates, thus improving the painting effect of the tabletop and further improving the production quality of the tabletop.

[0042] Refer to Figures 4-6, Further, the number of deformation members 26 is several. The deformation member 26 includes a main gear 261, a connecting rod 262 disposed at one end of the main gear 261, and a secondary gear 263 disposed at the end of the connecting rod 262 away from the main gear 261. One of the main gears 261 can be meshed with and driven by the deformation gear 25. A second main column 264 is rotatably connected to the bottom of one of the main gears 261. One end of the second main column 264 away from the main gear 261 is connected to the top of the painting table 13. A first main column 251 is rotatably connected to the bottom of the deformation gear 25. One end of the first main column 251 away from the deformation gear 25 is connected to the top of the painting table 13. The secondary gear 263 can be meshed with and driven by an adjacent main gear 261.

[0043] Refer to Figures 4-6 , Still further, the number of auxiliary members 27 is several. The auxiliary member 27 includes a main auxiliary plate 271 and a secondary auxiliary plate 272 rotatably connected to one end of the main auxiliary plate 271. One end of one of the main auxiliary plates 271 away from the secondary auxiliary plate 272 extends into the through groove 135 and is rotatably connected to the inner wall of the through groove 135. The secondary auxiliary plate 272 is in a Z shape. One corner side wall of one of the secondary auxiliary plates 272 is rotatably connected to the top of the deformation gear 25, and the other corner side wall is rotatably connected to the top of one of the main gears 261. One end of the secondary auxiliary plate 272 away from the main auxiliary plate 271 is rotatably connected to one end of an adjacent main auxiliary plate 271.

[0044] The main auxiliary plates 271 are distributed in a staggered manner, the secondary auxiliary plates 272 are distributed in an opposite manner, and the main auxiliary plates 271 and the secondary auxiliary plates 272 are arranged in sequence along the radial direction N.

[0045] Among them, during the left - right swing of the deformation gear 25, since one of the main gears 261 can be meshed with and driven by the deformation gear 25, when the deformation gear 25 swings, it will drive one of the main gears 261 to rotate in the same direction, so that the deformation gear 25 drives the main connecting plate 24, and one of the main gears 261 drives the connecting rod 262 and the secondary gear 263 to approach each other, thus achieving the purpose of bending. The rotation of the remaining deformation members 26 is achieved by the meshing transmission between the secondary gear 263 and the adjacent main gear 261, achieving the purpose of repeated bending, and further causing the deformation members 26 to deform and bend, which is consistent with the bending of the gaps between two irregular but regular plates, achieving the purpose of covering the gaps between two irregular but regular plates. It avoids the problem that the painting equipment repeatedly paints the gaps at the joint of the two plates, resulting in visible "step" - shaped marks at the joint of the two plates, thereby improving the painting effect of the table board and further improving the production quality of the table board.

[0046] During this process, one of the main auxiliary plates 271 will also swing synchronously with the left and right swinging of the main connecting plate 24 and the deformation gear 25. At this time, the corresponding secondary auxiliary plate 272 will not move. The two ends of its corners are connected to the corresponding second main column 264 and the first main column 251, while the remaining auxiliary parts 27 will swing with the bending of the corresponding deformation part 26.

[0047] Embodiment 2. Through the technical solution of Embodiment 1, although the problem that the painting device in the prior art repeatedly paints the gap at the joint of two plates, resulting in a "step" - shaped mark visible at the joint of the two plates, is solved; however, the problem of how to simultaneously shield the painted plates and the gap, without damaging the original paint surface, and still be able to make up for the missed painting on the surfaces of the plates on both sides of the gap has not been solved. For this reason, the following solution is now proposed: Refer to Figure 7 , specifically, the shielding unit 3 includes a fixed plate 31, an electric slide rail 32 arranged on one side of the fixed plate 31, an adjustment motor 33 arranged on the top of the electric slide rail 32, an adjustment shaft 34 arranged at the output end of the adjustment motor 33, and a micro - brush 35 rotatably connected to the end of the adjustment shaft 34 away from the adjustment motor 33.

[0048] Refer to Figure 7 , further, the top of the fixed plate 31 is connected to the bottoms of the corresponding main gear 261 and the secondary gear 263. A chute 311 is opened on the side wall of the fixed plate 31, and the electric slide rail 32 slides in the chute 311. The output end of the adjustment motor 33 passes through the bottom of the electric slide rail 32 and is connected to the adjustment shaft 34.

[0049] Among them, during the process of painting the surface of the plate, on the one hand, the corresponding electric slide rail 32 starts, driving the corresponding micro - brush 35 to slide synchronously. The micro - brush 35 rolls on the surface of the unpainted plate, so that the micro - brush 35 is evenly distributed flush with the painting point of the painting unit 1, avoiding the painting unit 1 from painting the paint on the surface of the unpainted plate. At this time, the micro - brush 35 should roll along the direction of the corresponding gap; on the other hand, the adjustment motor 33 starts, and its output end drives the adjustment shaft 34 and the micro - brush 35 to rotate synchronously, so that the rolling direction of the micro - brush 35 is consistent with the direction of the gap.

[0050] After the surface of one of the plates and the gap are painted, the deformation unit 2 is displaced above the painted plate, and the position of the painted plate close to the gap and the gap are shielded simultaneously. At this time, the micro brush 35 needs to be soaked with paint so that the micro brush 35 rolls on the surface of the painted plate, preventing the paint from overlapping at the gap. While shielding, on the one hand, the original painted surface is not damaged, and on the other hand, due to the design of the deformation unit 2 itself, the positions on the surfaces of the plates on both sides of the gap where the paint is missed can be filled and painted, thus ensuring the spraying quality of the tabletop and improving the spraying efficiency of the tabletop.

[0051] Embodiment 3, a partitioned panel painting method for an automatic lifting table, using the partitioned panel painting device for an automatic lifting table as described above, includes the following steps: S1. First, the staff place the spliced plates on the painting unit 1. Then, the painting unit 1 is started. It first moves above one of the plates and then performs the painting process. At this time, the deformation unit 2 is located above the gap of the spliced plates, only exposing the surface of one of the plates and the gap, and shielding the surface of the other plate close to the gap without interfering with the painting process.

[0052] S2. During the operation of S1, if the two plates are regular, the gaps between the two plates are on the same horizontal line. At this time, only the initial state of the deformation unit 2 is needed to shield the surface of the unpainted plate close to the gap. At the same time, during the painting process along the gap, on the one hand, the corresponding electric slide rail 32 is started to drive the corresponding micro brush 35 to slide synchronously. The micro brush 35 rolls on the surface of the unpainted plate, so that the micro brush 35 is evenly distributed flush with the painting point of the painting unit 1, preventing the painting unit 1 from painting the paint on the surface of the unpainted plate. On the other hand, the adjustment motor 33 is started, and its output end drives the adjustment shaft 34 and the micro brush 35 to rotate synchronously, so that the rolling direction of the micro brush 35 is consistent with the direction of the gap.

[0053] S3. After the surface of one of the plates and the gap are painted, the deformation unit 2 is displaced above the painted plate, and the position of the painted plate close to the gap and the gap are shielded simultaneously. At this time, the micro brush 35 needs to be soaked with paint so that the micro brush 35 rolls on the surface of the painted plate, preventing the paint from overlapping at the gap.

[0054] S4. If the tabletop is composed of two irregular but regular plates spliced together, the deformation motor 21 is activated to drive the movable bar 22 to rotate, so that the movable bar 22 can slide within the movable plate 23 and drive the movable plate 23 to swing left and right. As a result, the main connecting plate 24 and the deformation gear 25 swing left and right synchronously, and then the deformable member 26 deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular plates, achieving the purpose of covering the gaps between the two irregular but regular plates.

[0055] S5. During the operation of S4, on the one hand, the corresponding electric slide rail 32 is activated to drive the corresponding micro brush 35 to slide synchronously. The micro brush 35 rolls on the surface of the unpainted plate, making the micro brush 35 evenly distributed flush with the painting point of the painting unit 1, avoiding the painting unit 1 from painting the surface of the unpainted plate when painting.

10. A partitioned panel painting method for an automatic lifting table, which uses the partitioned panel painting device for an automatic lifting table as described in any one of claims 1-9, characterized in that, Including the following steps: S1. First, the staff places the spliced board on the painting unit (1). Subsequently, the painting unit (1) is started. It first moves to above one of the boards and then performs the painting process. At this time, the deformation unit (2) is located above the gap between the spliced boards, only exposing the surface of one board and the gap, covering the surface of the other board close to the gap, and not interfering with the painting process. S2. During the operation in S1, if the two boards are regular, the gaps between the two boards are on the same horizontal line. At this time, only the initial state of the deformation unit (2) is needed to cover the surface of the unpainted board close to the gap. At the same time, during the painting process along the gap, on the one hand, the corresponding electric slide rail (32) is started to drive the corresponding micro brush (35) to slide synchronously. The micro brush (35) rolls on the surface of the unpainted board, so that the micro brush (35) is evenly distributed flush with the painting point of the painting unit (1), avoiding the painting unit (1) from painting the paint on the surface of the unpainted board. On the other hand, the adjustment motor (33) is started, and its output end drives the adjustment shaft (34) and the micro brush (35) to rotate synchronously, so that the rolling direction of the micro brush (35) is consistent with the direction of the gap. S3. After the surface and gap of one of the boards are painted, the deformation unit (2) is moved to above the painted board, covering both the position of the painted board close to the gap and the gap at the same time. At this time, the micro brush (35) needs to be wetted with paint, so that the micro brush (35) rolls on the surface of the painted board, preventing the paint from overlapping at the gap. S4. If the tabletop is spliced by two irregular but regular boards, the deformation motor (21) is started to drive the movable bar (22) to rotate, so that the movable bar (22) can slide in the movable plate (23) and drive the movable plate (23) to swing left and right, so that the main connecting plate (24) and the deformation gear (25) swing left and right synchronously, and then the deformation part (26) deforms and bends, which is consistent with the bending of the gaps between the two irregular but regular boards, achieving the purpose of covering the gaps between the two irregular but regular boards. S5. During the operation in S4, on the one hand, the corresponding electric slide rail (32) is started to drive the corresponding micro brush (35) to slide synchronously. The micro brush (35) rolls on the surface of the unpainted board, so that the micro brush (35) is evenly distributed flush with the painting point of the painting unit (1), avoiding the painting unit (1) from painting the paint on the surface of the unpainted board. At this time, the micro brush (35) should roll along the corresponding gap direction. On the other hand, the adjustment motor (33) is started, and its output end drives the adjustment shaft (34) and the micro brush (35) to rotate synchronously, so that the rolling direction of the micro brush (35) is consistent with the direction of the gap.
