Description

Jig for coating{Jig for coating}

The present invention relates to a jig for painting, and more particularly, to a jig for painting that is coupled to a support rod to improve productivity while minimizing unnecessary waste of paint or coating liquid.

In general, since the process of painting or coating the surface of an article such as a smartphone or a cosmetic case requires both precision and productivity, a chain conveyor type automatic painting device is used. The chain conveyor type automatic painting device has a plurality of support rods spaced apart from each other in a chain arranged to circulate continuously through an antistatic chamber for removing static electricity, a painting booth for spraying paint or coating liquid, and a drying room for drying the paint or coating liquid. It is installed, and an article to be painted or coated is fixed on the top of each support rod, and it moves with the chain, and the article is painted or coated. In such a conventional automatic painting apparatus, since one article is fixed to one support rod, painting or coating is possible only as many as the number of support rods installed in the chain. Therefore, when there are a large number of items to be painted or coated, productivity decreases, and when the size of the items to be painted or coated is small, paint or coating liquid is sprayed between the spaced support rods and not only stains the chain, but also makes paint or coating liquid unnecessary. There is a wasted problem.

Accordingly, there is a need for a jig for painting that is coupled to the support rod to improve productivity while minimizing unnecessary waste of paint or coating liquid.

It is provided to completely inform the scope of the invention to those who have, and the invention is only defined by the scope of the claims. The same reference numerals refer to the same components throughout the specification.

Hereinafter, with reference to FIGS. 1 to 7, a jig for painting according to an embodiment of the present invention will be described in detail.

The jig for painting according to an embodiment of the present invention supports a plurality of objects to be painted or coated on the surface, and can be used in conjunction with a chain conveyor type automatic painting device.

The painting jig can paint or coat a larger amount of the object to be painted at once than the number of support rods rotatably coupled to the chain portion, thereby improving productivity. In particular, since the painting jig is seated on the support rod to support the object to be painted, it is possible to minimize the paint or coating liquid from being deposited on the chain and prevent unnecessary waste of the paint or coating liquid. In addition, since one support rod rotates a plurality of extension rods at once by rotating rotational force and paints or coats the object to be painted, there is an excellent feature in terms of efficiency.

Hereinafter, with reference to FIGS. 1 to 4, it will be described in detail with respect to the jig for painting (1).

1 is a bottom perspective view showing a jig for painting according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a state in which a cover portion of the jig for painting is opened. 3 is a cross-sectional view showing a painting jig cut in the longitudinal direction, and FIG. 4 is a cross-sectional view showing a state in which a painting object is coupled to the painting jig.

The jig for painting 1 according to the present invention is rotatably coupled to the top of the chain portion (see C of FIG. 5) to form a closed loop along the paint spraying path, and rotates along the chain portion (C). It is supported by at least two support rods (R) among a plurality of support rods (see R in FIG. 5) spaced apart from each other. A plurality of jigs for painting (1) may be arranged in a row along the chain portion (C), respectively, the main body 10, the rotating rod 20, a plurality of extension rods 30, and the rotating unit 40 ).

The main body 10 is a cylindrical member with an open top and is mounted on the top of a plurality of support rods R. That is, the main body 10 is mounted in a horizontal direction on the top of at least two support rods R spaced apart from each other. Since the main body 10 is horizontally seated on the top of the at least two support rods R spaced apart from each other, paint or coating liquid is sprayed between the support rods R to minimize burying in the chain portion C. The shape of the main body 10 is not limited, but may be formed in a form having a narrow width and a long length so that more extension rods 30 to be described later can be coupled. The body 10 is coupled to the rotating rod 20 on the outside.

The rotating rod 20 is a rod or rod-shaped member with a space formed therein, and is vertically disposed on the outer lower surface of the main body 10. The rotating rod 20 is rotatably coupled to the main body 10 and is coupled with any one of a plurality of support rods R supporting the main body 10 to receive a rotational driving force. That is, any one of the plurality of support rods (R) is inserted and fixed into the rotating rod (20), and the rotating rod (20) receives a rotational driving force from the support rod (R) inserted and fixed therein to It rotates integrally. The rotating rod 20 may have an inner circumferential surface having a size corresponding to the outer circumferential surface of the support rod R so that the support rod R can be inserted and fixed.

Meanwhile, a plurality of extension rods 30 may be coupled to the main body 10. The extension rod 30 is a rod or rod-shaped member, and is disposed upright on the main body 10 so that the lower end is rotatably coupled to the main body 10, and the coating object A is mounted on the upper part. The painting object (A) may be formed indented in the lower portion so that the upper portion of the extension bar 30 can be inserted and fixed. The extension rod 30 may be formed in a cone shape by gradually decreasing the diameter of the upper portion on which the object to be painted (A) is mounted, and thus, the object to be painted (A) of various diameters can be mounted. A plurality of extension rods 30 may be arranged along the length direction of the main body 10, and in this case, the number of extension rods 30 may be greater than the number of support rods R supporting the main body 10. have. Since the number of extension rods 30 is more than the number of support rods (R) supporting the main body 10, compared to the conventional case of painting or coating by attaching a painting object (A) to each support rod (R). It is possible to paint or coat a larger amount of the object to be painted (A) at once, so that productivity can be improved.

An elastic clip 70 may be coupled to an upper end of each of the extension rods 30. The elastic clip 70 is to fix the coating object (A) to the extension rod 30, and may include a fixing plate 71 and a plurality of wing portions 72. The fixing plate 71 is a plate-like member having a width corresponding to the upper surface of the extension rod 30 and may be fixed to the upper surface of the extension rod 30. For example, the fixing plate 71 may be fixed by screwing or uneven coupling to the upper surface of the extension bar 30. A plurality of wing portions 72 are coupled to the outer peripheral surface of the fixing plate 71. The wing portion 72 is to apply an elastic force to the object to be painted (A), and a plurality of them are radially disposed on the outer circumferential surface of the fixing plate 71 to be elastically coupled. The plurality of wing portions 72 are arranged in a radially unfolded state from the extension rod 30, as shown in FIG. 4(a), and are pressed by the painting object (A) to the FIG. 4(b). As shown, it may be in close contact with the outer peripheral surface of the extension bar (30). Since the elastic clip 70 is coupled to the upper end of the extension bar 30, the coupling and separation of the painting object A and the extension bar 30 can be made easily.

The plurality of extension rods 30 may be rotated simultaneously by the rotation unit 40. The rotating unit 40 rotates the plurality of extension rods 30 by receiving driving force from the rotating rod 20 by rotatably connecting the rotating rod 20 and the plurality of extension rods 30 to each other. The rotation unit 40 may include a driving gear 41 and a plurality of driven gears 42. The driving gear 41 is a gear having a rotating shaft installed on the rotating rod 20 and may rotate by receiving a driving force from the rotating rod 20. The driving gear 41 may be accommodated in the main body 10, and if necessary, an extension rod 30 may be installed on the upper side. The plurality of driven gears 42 are installed on the plurality of extension rods 30, respectively, and mesh with each other, but at least one of them may mesh with the driving gear 41. In other words, the plurality of driven gears 42 are interposed between the extension rod 30 and the body 10, respectively, so that the rotation shaft is rotatably coupled to the body 10, and meshes with the adjacent driven gear 42, but at least one Meshes with the drive gear 41. Therefore, when the driving gear 41 rotates, the plurality of driven gears 42 rotate at once and the plurality of extension rods 30 rotate, and thus, the coating object mounted on each of the extension rods 30 ( A) can be painted or coated as a whole while rotating 360°. The drive gear 41 and the plurality of driven gears 42 have the same gear ratio, and may be arranged to be meshed with each other in series along the moving direction of the chain portion C. Since the gear ratios of the drive gear 41 and the plurality of driven gears 42 are the same, the speed is the same as when the coating object (A) is mounted directly to the support rod (R) without using the painting jig (1). It can be painted or coated while rotating the extension rod 30 and the object to be painted (A). That is, by preventing the extension rod 30 and the object to be painted (A) from rotating excessively quickly or slowly, the outer surface of the object to be painted (A) may be uniformly painted or coated. In the drawing, it is shown that the driving gear 41 and the plurality of driven gears 42 are formed as spur gears with gear teeth formed on the outer circumferential surface, respectively, and are engaged in series along the moving direction of the chain part C, but the present invention is not limited thereto. , The shape and arrangement of the driving gear 41 and the driven gear 42 may be variously modified. In addition, the rotation unit 40 is not limited to including a driving gear 41 and a plurality of driven gears 42, and various structures that rotatably connect the rotating rod 20 and the plurality of extension rods 30 Can be transformed into For example, the rotating unit 40 may be formed in a conveyor belt structure to rotatably connect the rotating rod 20 and the plurality of extension rods 30.

Meanwhile, a guide part 50 may be formed under the main body 10. The guide part 50 guides the remaining support rods R not connected to the rotating rod 20 among the plurality of support rods R supporting the main body 10 to prevent separation, and the outer side of the main body 10 It may be disposed spaced apart from the rotating rod 20 on the lower surface. As described above, any one of the plurality of support rods R is inserted and fixed to the rotating rod 20 to transmit the rotational driving force. At this time, the main body 10 can rotate around the rotating rod 20, and when the main body 10 rotates, the object A is deviated from the paint spray path, so that painting or coating is not properly performed. do. Accordingly, the present invention forms a guide portion 50 for guiding the support rod R not connected to the rotating rod 20 under the main body 10, and thus, the separation of the support rod R and the main body ( 10) is prevented from rotating so that painting or coating can be easily performed. As shown, the guide portion 50 may include a wall that faces each other with the support rod R interposed therebetween, and is disposed side by side to guide both sides of the support rod R. In the drawing, it is shown that two pairs of guide parts 50 are arranged in a line along the length direction of the main body 10, but the number of guide parts 50 is not limited thereto, and the number of guide parts 50 is supported for supporting the main body 10 It can be adjusted according to the number of rods (R). In addition, the guide portion 50 is not limited to include a wall that guides both sides of the support rod (R), the guide portion 50 is formed in a groove shape by recessing the lower surface of the main body 10 toward the top. May be.

In addition, the cover portion 60 may be detachably coupled to the main body 10. The cover part 60 covers the upper side of the main body 10, and a through hole 60a through which the plurality of extension rods 30 pass may be formed. As the cover part 60 covers the upper side of the main body 10, the driving gear 41 and the driven gear 42 accommodated in the main body 10 are not covered with paint or coating liquid, so the driving gear 41 and the driven gear 42 ) Can be smoothly engaged. In the drawings, a plurality of through-holes 60a are formed in the cover part 60, and each through-hole 60a is shown to be formed in a shape corresponding to the outer circumferential surface of the extension bar 30, but is not limited thereto, The shape and number of the through holes 60a may be variously modified. For example, a single through hole 60a formed in a rectangular shape may be formed in the cover part 60 so that the plurality of extension rods 30 can pass therethrough.

Hereinafter, the operation of the painting jig 1 will be described in more detail with reference to FIGS. 5 to 7.

Figure 5 is a state diagram of the use of the jig for painting, Figures 6 and 7 are operation diagrams for explaining the operation of the jig for painting.

The jig for painting (1) according to the present invention can paint or coat a larger amount of the object to be painted (A) at once than the number of support rods (R) rotatably coupled to the chain part (C), thereby increasing productivity. It can be improved. In particular, since the jig for painting (1) is seated on the support rod (R) to support the object to be painted (A), it is possible to minimize the intrusion of paint or coating liquid on the chain part (C), and the paint or coating liquid is unnecessary. Can be prevented. In addition, since one support rod (R) rotates the plurality of extension rods 30 at once with the rotational force and paints or coats the object to be painted (A), there is an excellent advantage in terms of efficiency.

First, referring to FIG. 5, the chain portion C is connected to a pair of sprockets S1 and S2 in which one side and the other side are respectively spaced apart from each other to form a closed loop along the paint spraying path. At the upper end of the chain portion (C), a support rod (R) is rotatably coupled to move along the chain portion (C), and a plurality of support rods (R) are arranged spaced apart from each other. The painting jig (1) is supported by at least two support rods (R), one of the at least two support rods (R) is inserted and fixed to the rotating rod (20) and the rest is guided by the guide unit (50). do. Each of the plurality of extension rods 30 is equipped with a coating object (A) on the upper part, and at this time, the wing portion 72 of the elastic clip 70 is pressed by the coating object (A) to While in close contact with the outer circumferential surface, the object to be painted (A) can be fixed to the extension bar (30).

Meanwhile, the rotating rod 20 rotates by receiving a rotational driving force from the inserted and fixed support rod R, and as the rotating rod 20 rotates, as shown in FIGS. 6 and 7, the driving gear 41 rotates. Thus, the plurality of driven gears 42 are collectively rotated. When a plurality of driven gears 42 rotate, the extension rod 30 installed in each driven gear 42 rotates, and as the extension rod 30 rotates, the painting object A rotates while painting or coating. This is done. Since the upper side of the main body 10 is covered by the cover part 60, the driving gear 41 and the driven gear 42 are smoothly engaged because no paint or coating liquid is applied to the driving gear 41 and the driven gear 42. And can be rotated.
