Description

Technical Field

[0001] The present invention relates to the technical field of spraying equipment, and more specifically, to a spraying equipment used for producing a supporting structure of an automatic lifting table. Background Art

[0002] The supporting structure of the automatic lifting table is its core part, which determines the stability, lifting speed and load-bearing capacity of the table. Common supporting structures include dual motors, single motor, pneumatic and hydraulic systems. The dual motor supporting structure drives the lifting columns on both sides through two motors respectively, providing high stability and fast lifting, which is suitable for large-size desktops and heavy loads. The single motor structure drives the lifting columns on both sides through one motor. It has a lower cost but relatively weaker lifting speed and load-bearing capacity.

[0003] At present, the spraying equipment produced by the automatic lifting table support structure on the market usually uses an automatic spraying robot arm to support the workpiece through the mounting holes, pass the steel wire through the supporting holes of the workpiece, and after the workpiece is suspended in the air by the steel wire, the automatic spraying robot arm sprays the surface of the workpiece. The existing automatic spraying robot arm evenly distributes the paint on the surface of the workpiece to form the required paint layer.

[0004] Because the steel wire supports the workpiece during the process of spraying paint on the workpiece, and there are many mounting holes on the surface of the workpiece, during the process of the automatic spray robot arm painting the workpiece, the paint will enter the inside of the workpiece through the mounting holes, and the paint will solidify on the inner wall of the workpiece, causing tolerance errors on the inner wall of the workpiece, and scratching the telescopic component that will be installed inside the workpiece later. If too much paint enters, the telescopic component cannot enter the inside of the workpiece to achieve the telescopic effect, which affects the final quality and appearance of the product, and when the paint enters the through hole, it will also cause paint accumulation on the side wall of the installation through hole. During subsequent installation, the threaded hole needs to be cleaned first. If the paint directly blocks the installation through hole, secondary processing will be required. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a spraying device for producing an automatic lifting table support structure.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0022] By adopting the above technical solution, the paint touch-up module is set to be ejected toward the mounting hole. After being ejected, the paint touch-up module expands outward, and the roller brush column repairs the damaged paint part.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0047] See also Figure 1-13 , the present invention provides the following technical solutions:

[0048] Example 1, see Figure 1 and Figure 2 A spraying device for the production of an automatic lifting table support structure includes a spraying unit 1, on which a support product 2 is arranged, the spraying unit 1 can transport the support product 2 and apply paint to the spraying unit 1, the spraying unit 1 includes a conveying support foot 11, the conveying support foot 11 is arranged equidistantly, a conveying bracket 12 is installed above the conveying support foot 11, the conveying bracket 12 is installed above the conveying support foot 11, the conveying bracket 12 is arranged in an annular manner, and a conveying guide rail 13 is arranged at one end of the conveying bracket 12 close to the conveying support foot 11, The conveying rail 13 conveys the support product 2, and a spraying base 14 is set in the middle position of the conveying bracket 12. A spraying robot arm 15 is installed above the spraying base 14, and a spray gun 16 is installed at the output end of the spraying robot arm 15. The spraying robot arm 15 can adjust the position of the spray gun 16 to spray different positions of the support product 2. The spraying base 14 provides rotation conditions for the spraying robot arm 15. During this process, the conveying rail 13 continuously conveys the support product 2, thereby achieving the purpose of continuous spraying of multiple support products 2.

[0049] See also Figure 3The supporting product 2 includes a supporting body 21, which is an important component of the supporting structure of the automatic lifting table and provides support for the entire lifting table. Mounting holes 22 are equidistantly arranged on the supporting body 21, and the mounting holes 22 provide installation conditions for the supporting body 21. The mounting holes 22 are equidistantly arranged on the supporting body 21 to facilitate subsequent installation.

[0050] Since the prior art only supports the supported product 2 by passing a steel wire through the mounting hole 22 during the clamping process, the supported product 2 will shake during the spraying process by the spray gun 16, resulting in irregular shaking during the spraying process and uneven paint spraying.

[0051] See also Figure 5 and Figure 6 A clamping unit 3 is equidistantly arranged above the spraying unit 1. The clamping unit 3 is used to assist in positioning the supporting product 2. The specific structure of the clamping unit 3 is as follows:

[0052] The clamping unit 3 includes a clamping slider 31, which is slidably mounted on the conveying guide rail 13, and the clamping slider 31 is slidably mounted on the conveying bracket 12. A rotating block 32 is rotatably mounted below the clamping slider 31, and the rotating block 32 is driven by a motor. The rotating block 32 can rotate on the clamping slider 31, and a swing support block 33 is installed below the rotating block 32. The swing support block 33 is connected to the rotating block 32. When the rotating block 32 rotates, the swing support block 33 rotates simultaneously with the rotating block 32. The shape of the swing support block 33 is special-shaped, and the swing support block 33 is connected to the rotating block 32 in a cylindrical position. A connecting block 35 is installed in a fit at the bottom of the block 33, and the bottom of the swing support block 33 is fitted with the top of the connecting block 35 to form a sphere. Grooves are equidistantly arranged at the upper end of the connecting block 35, and a rotating bead 34 is slidably arranged in the groove of the connecting block 35. An arc groove fitting with the rotating bead 34 is provided at the lower end of the swing support block 33, and a support plate mechanism 36 is installed at the lower end of the connecting block 35. The rotating bead 34 can allow the connecting block 35 to move in any direction in the swing support block 33. During the movement, the rotating bead 34 rubs against the inner wall of the swing support block 33, so that the swing angle and speed of the connecting block 35 are kept within a controllable range.

[0053] See also Figure 5 and Figure 6The support plate mechanism 36 includes a mounting plate 363, which is circular in shape, with a hollow rectangular groove in the middle of the mounting plate 363, a threaded shaft 364 is rotatably installed in the middle of the rectangular groove of the mounting plate 363, a support plate mounting block 361 is provided on the side wall of the mounting plate 363, and a support plate motor 362 is installed on the support plate mounting block 361, the output end of the support plate motor 362 penetrates the mounting plate 363, and the output end of the support plate motor 362 is connected to the threaded shaft 364, and the support plate motor 362 can drive the threaded shaft 364 to rotate in the mounting plate 363.

[0054] See also Figure 5 and Figure 6 The first slider 365 and the second slider 366 are rotatably mounted on the threaded shaft 364. The middle portion of the first slider 365 that fits with the threaded shaft 364 is a positive thread, and the middle portion of the second slider 366 that fits with the threaded shaft 364 is a reverse thread. A rectangular block is provided in the middle of the threaded shaft 364, and the rectangular block of the threaded shaft 364 is fixedly connected to the mounting plate 363. A support plate 367 is installed below the second slider 366 and the first slider 365. When the threaded shaft 364 rotates forward, the first slider 365 and the second slider 366 moves toward the outer wall of the mounting plate 363, and the support plate 367 moves toward the outer wall of the mounting plate 363. The support plate 367 supports the supported product 2. When the threaded shaft 364 reverses, the first slider 365 and the second slider 366 move toward the middle of the mounting plate 363, and the support plate 367 moves toward the middle of the mounting plate 363, releasing the support for the processed supported product 2 for easy removal. The support plate motor 362 drives the threaded shaft 364 to rotate in the mounting plate 363, driving the support plate 367 to move on the threaded shaft 364.

[0055] Through the friction of the rotating ball 34, the connecting block 35 can move in any direction in the swing support block 33. During the movement, the rotating ball 34 rubs against the inner wall of the swing support block 33, so that the swing angle and speed of the connecting block 35 are maintained within a controllable range, thereby achieving the effect of facilitating the loading and unloading of the supporting product 2 and limiting the swing angle and speed of the connecting block 35.

[0056] In the second embodiment, since the steel wire supports the workpiece during the process of spraying paint on the workpiece, and there are many mounting holes on the surface of the workpiece, during the process of the automatic spray robot arm 15 coating the workpiece, the paint will enter the interior of the workpiece through the mounting hole 22, and the paint will solidify on the inner wall of the workpiece, causing tolerance errors on the inner wall of the workpiece, and scratching the telescopic component that will be installed inside the workpiece later. If too much paint enters, the telescopic component cannot enter the interior of the workpiece to achieve the telescopic effect, which affects the final quality and appearance of the product, and when the paint enters the through hole, it will also cause paint accumulation on the side wall of the mounting through hole. During subsequent installation, the threaded hole needs to be cleaned first. If the paint directly blocks the mounting through hole, secondary processing will be required.

[0057] See also Figure 2 and Figure 3 A supporting product 2 is installed below the clamping unit 3, a blocking unit 4 is installed below the clamping unit 3, and repairing units 5 are installed equidistantly on the blocking unit 4. When the clamping unit 3 positions the supporting product 2, the blocking unit 4 cooperates with the repairing unit 5 to block the mounting hole 22 inside the supporting product 2 to prevent paint from entering the interior of the supporting body 21.

[0058] See also Figure 7 The blocking unit 4 includes a connecting rod 41, which is installed below the support plate mechanism 36. The upper end of the connecting rod 41 is connected to the rectangular block in the middle position of the threaded shaft 364. A connecting plate 42 is installed below the connecting rod 41. The diameter of the connecting plate 42 is smaller than the internal length of the supporting product 2. Displacement support frames 44 are symmetrically installed on both sides below the connecting plate 42. The upper shape of the displacement support frame 44 is L-shaped, and the main body of the displacement support frame 44 is a hollow rectangle. Two movable sliding rods are symmetrically arranged on one side of the displacement support frame 44 close to the center of the connecting plate 42.

[0059] See also Figure 7 A blocking motor 45 is installed at the L-shaped position above the two displacement support frames 44. The output end of the blocking motor 45 penetrates the displacement support frame 44. A sliding rod 49 is installed at the output end of the blocking motor 45. The sliding rod 49 is set in the middle position of the displacement support frame 44. The sliding rod 49 is provided with a thread, and the sliding rod 49 can rotate in the displacement support frame 44.

[0060] See also Figure 7Four sliders 47 are equidistantly installed on the slide bar 49, and threads are arranged inside the sliders 47, and the threads inside the sliders 47 match with the threads on the slide bar 49. Hinge rods 46 are installed on the side walls of the four sliders 47. A connecting slider 48 is installed on the side of the displacement support frame 44 away from the repair unit 5. The connecting slider 48 is installed on two symmetrically arranged movable slide bars of the displacement support frame 44. A fixing plate 43 is installed at the center position of the two displacement support frames 44. When the blocking motor 45 drives the slide bar 49 to rotate, the four sliders 47 move downward, and the hinged rod 46 limits the downward movement distance of the four sliders 47 to prevent a single slider 47 from moving downward.

[0061] See also Figures 8 to 13 The repair unit 5 includes a repair block 51, a controller 52 is installed on the side wall of the repair block 51, and a camera 53 is installed on the side of the controller 52 near the opening of the repair block 51. The camera 53 first takes an image of the mounting hole 22, and converts the taken photo into an electrical signal to transmit to the controller 52. The controller 52 is provided with a database inside, and the database is provided with identification photos of the mounting hole 22 at different angles under different brightness. When the controller 52 receives the photo sent by the camera 53, it will compare it with the identification photos of the mounting hole 22 under different brightness in the internal database, and pre-identify the position of the mounting hole 22. According to the obtained photos of the position of the mounting hole 22, the position of the mounting hole 22 is divided into five types: left position, upper position, middle position, lower position, and right position. The controller 52 compares the photos of the mounting hole 22 with the identification photos of different positions of the mounting hole 22 in the internal database, identifies the position of the mounting hole 22, and takes photos according to the obtained position of the mounting hole 22, and divides the position adjustment of the mounting hole 22 into two adjustment modes: up and down adjustment and left and right adjustment.

[0062] As the blocking unit 4 drives the repair unit 5 to block the mounting hole 22, the blocking unit 4 moves downward, and after moving to a suitable position, the repair unit 5 extends out to block the mounting hole 22, and the spray gun 16 sprays the support body 21. At this time, the paint on the support body 21 and the paint blocked by the repair unit 5 on the mounting hole 22 form a main body. When the repair unit 5 retracts subsequently, the paint forming a main body will be destroyed. When the paint on the mounting hole 22 is destroyed, part of the paint on the support body 21 will be destroyed synchronously, resulting in defects in the product.

[0063] The repair block 51 is hollow, with a driving cylinder 54 installed in the middle of the repair block 51, and a lifting block 55 installed at the output end of the driving cylinder 54. The driving cylinder 54 drives the lifting block 55 to be ejected or retracted. A repair motor 56 is installed in the middle position of the lifting block 55, and a repair mechanism 57 is installed at the output end of the repair motor 56. The repair motor 56 drives the repair mechanism 57 to rotate.

[0064] The repair mechanism 57 includes a repair support block 572, which is in an irregular shape. The repair support block 572 extends outward at five angles. The repair support block 572 is provided with a paint touch-up module 571 in a circular and equidistant manner. A repair slider 573 is installed in the slot on the repair support block 572. A circular sliding column is provided on the lower side of the repair slider 573. The upper side of the repair slider 573 is fixedly connected to the paint touch-up module 571. When the repair slider 573 slides outward, the paint touch-up module 571 slides outward synchronously. A driving module 574 is installed below the repair support block 572. The repair mechanism 57 also includes a repair shaft 575, one end of the repair shaft 575 away from the paint repair module 571 is connected to the output end of the repair motor 56, the repair shaft 575 penetrates the driving module 574 and is connected to the middle position of the repair support block 572, a protective plate 576 is installed below the driving module 574, a fixing block 577 is installed at the lower protruding end of the repair support block 572, the protective plate 576 is connected below the fixing block 577, and the fixing block 577 is arranged on the outer side of the driving module 574 to prevent the driving module 574 from interfering with the fixing block 577 during operation.

[0065] When the driving cylinder 54 is pushed out, the paint touch-up module 571 forms a disc to block the mounting hole 22. After the spray gun 16 has finished spraying, the driving cylinder 54 continues to push outward, which can prevent the paint from sticking to the outer wall of the paint touch-up module 571 and being unable to be retracted later. At the same time, the protective disc 576 partially blocks the mounting hole 22. After the paint touch-up module 571 is pushed out, the protective disc 576 blocks the mounting hole 22 for the second time, thereby protecting the mounting hole 22 and preventing the paint from entering the inner wall of the support body 21 when the paint touch-up module 571 repairs the paint around the mounting hole 22, causing deviations in the tolerance of the inner wall of the support body 21.

[0066] A disc is formed by the paint touch-up module 571 to drive the cylinder 54 to push out and block the mounting hole 22. After the spray gun 16 has finished spraying, the drive cylinder 54 continues to push out to prevent the paint from sticking to the outer wall of the paint touch-up module 571 and the support body 21, thereby achieving the effect that the paint touch-up module 571 can directly break the hole after blocking the mounting hole 22.

[0067] The paint touch-up module 571 includes a paint touch-up block 5711, a paint scraper 5712 is installed on the arc-shaped outer side of the paint touch-up block 5711, and the paint scraper 5712 can scrape off excess paint. The paint touch-up block 5711 is symmetrically installed with a paint touch-up support block 5713 on the arc-shaped inner side of the paint scraper 5712. A central shaft 5714 is rotatably installed in the middle of the paint touch-up support block 5713, and the central shaft 5714 can rotate on the paint touch-up support block 5713. A roller brush column 5715 is rotatably installed on the central shaft 5714, and the roller brush column 5715 can touch up the position of the support body 21 near the mounting hole 22. The protective plate 576 An active motor 5743 is installed on the top, and a driven wheel 5741 is arranged in the middle upper part of the protective plate 576. The output of the active motor 5743 is installed with a driving wheel 5742. The active motor 5743 drives the driving wheel 5742 to rotate. The driving wheel 5742 is meshed with the driven wheel 5741. An arc-shaped slide groove is arranged inside the driven wheel 5741. The circular slide column of the repair slider 573 is installed in the arc-shaped slide groove of the driven wheel 5741. When the driven wheel 5741 rotates, it can drive the circular slide column of the repair slider 573 to move in the arc-shaped slide groove, and synchronously drive the repair slider 573 to extend outward or retract.

[0068] When the paint touch-up module 571 is pushed out of the mounting hole 22, the paint touch-up module 571 expands outward, and the roller brush column 5715 repairs the damaged paint part. The repair motor 56 rotates, driving the roller brush column 5715 to rotate and perform rolling brushing. In the process of the paint touch-up module 571 shrinking toward the middle, it can continue to repair to the position of the mounting hole 22, and the paint scraper plate 5712 can scrape the paint to the same thickness to avoid burrs. After the paint is repaired, the paint touch-up module 571 retracts into the inside of the support body 21, and the support product 2 is transported to the required position. The clamping unit 3 releases the clamping and unloads.

[0069] The paint touch-up module 571 is pushed out toward the mounting hole 22, and after being pushed out, the paint touch-up module 571 expands outward, and the roller brush column 5715 repairs the damaged paint part. The repair motor 56 rotates, driving the roller brush column 5715 to rotate and perform rolling brushing. In the process of the paint touch-up module 571 shrinking toward the middle, it can continue to repair to the position of the mounting hole 22, thereby achieving the effect of performing secondary repairs on the paint around the mounting hole 22 after the paint touch-up module 571 is pushed out.

[0070] When the repair unit 5 is extended, the repair shaft 575 is in the mounting hole 22 , and when the spray gun 16 sprays paint on the support body 21 , the support product 2 will shake, causing the shaking stress to be concentrated on the repair shaft 575 , causing damage to the repair unit 5 .

[0071] By allowing the connecting block 35 to move in any direction in the swing support block 33, the blocking unit 4 is synchronously driven to move, thereby avoiding excessive stress on the repair unit 5 when the spray gun 16 sprays paint on the outside of the supported product 2, thereby preventing the repair unit 5 from being damaged, thereby achieving the effect of following the movement of the repair unit 5 and the supported product 2.

[0072] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
