The lower carrier 20 includes a carrying platform 2 and a lower shielding frame 3. The loading platform 2 includes a carrier 21, a connecting post 222 and a plurality of lower magnetic members 23. The carrier board 21 is configured to carry the lower shielding frame 3, the painting material 1 and the upper mask 40. The carrier board 21 includes a substrate portion 211, a convex portion 212 protruding from the top end of the substrate portion 211, and a shoulder portion 213. The outer contour of the convex portion 211 is smaller than the outer contour of the substrate portion 211. The shoulder portion 213 is formed on the outer peripheral surface 214 of the side edge of the substrate portion 211 for carrying the lower shielding frame 3, so that the convex portion 212 and the substrate portion 211 and The shoulder portion 213 is gradually expanded in a stepped manner.

A screw hole 215 extending from a bottom end of the substrate portion 211 toward the convex portion 212 is formed in the middle of the carrier 21, and one end of the connecting post 22 is screwed to the screw hole. The other end is connected to a rotary drive mechanism (not shown). Thereby, the rotary driving mechanism can drive the paint masking fixture 200 and the paint to be painted 1 to perform a horizontal rotary motion, so that the spray paint sprayed from the spray gun (not shown) can be sprayed on the paint surface 114 to be painted.

The carrier board 21 is further formed with a plurality of mounting blind holes 216 extending from the bottom end of the substrate portion 211 to the convex plate portion 212 with the opening facing downward, and the number of the mounting blind holes 216 is the same as the number of the lower magnetic members 23.

The pressing wall 41 is for pressing against the non-painted surface 121 of the paint to be painted 1, and the carrying wall 42 is for carrying the upper magnetic member 5. The upper magnetic member 5 of the present embodiment is exemplified by a metal pressing plate. The upper magnetic member 5 can be attracted by the magnetic force of the lower magnetic member 23 to press the upper shielding frame 4 toward the painting member 1. In order to make the pressing wall 41 have good adhesion when it is pressed against the non-painted surface 121, the bearing wall 42 has good structural strength to carry the magnetic member 5, In the embodiment, the upper shadow frame 4 is made of a soft plastic material in a two-shot injection molding manner. The pressing wall 41 of the upper shielding frame 4 includes an elastic pressing wall portion 411 for pressingly contacting the non-painting surface 121, and a connecting wall portion 412 formed at the top end of the elastic pressing wall portion 411. The bearing wall 42 is formed. At the top end of the connecting wall portion 412, the hardness of the connecting wall portion 412 and the carrying wall 42 is greater than the hardness of the elastic pressing wall portion 411. Thereby, the elastic pressing wall portion 411 can maintain good adhesion when it is in tight contact with the non-painting surface 121 to prevent the occurrence of capillary phenomenon, and at the same time, the bearing wall 42 has good structural strength to carry the magnetic member 5 to The upper shadow frame 4 is prevented from being deformed by the upper magnetic member 5 to cause deformation.

The elastic pressing wall portion 411 of the pressing wall 41 has a pressing surface 413 for pressingly contacting the non-painting surface 121, and the elastic pressing wall portion 411 and the connecting wall portion 412 together define an outer wall surface 414. The wall 414 is used to align with the contour 122 of the non-painted surface 121 (shown in FIG. 2) whereby the upper mask 40 can completely shield the non-painted surface 121. Referring to FIG. 9 together, the carrying wall 42 of the upper shielding frame 4 defines a rectangular positioning groove 421, and the carrying wall 42 includes a shielding wall portion 422 protruding from the outer wall surface 414. The shielding wall portion 422 has a The lower surface 423 to which the outer wall surface 414 is joined, the lower surface 423 and the outer wall surface 414 together define a corner space 45. When the spray paint sprayed from the spray gun is sprayed into the corner space 45 via the external environmental space S, since the pressure in the corner space 45 is different from the pressure at the outer environmental space S, and the pressure in the corner space 45 is greater than the external environmental space S Therefore, when the spray spray is sprayed to the corner space 45, the flow rate is reduced and the flow rate is reduced, so that the amount of adhesion of the paint adhered to the surface to be painted 114 is from the external environmental space S toward the corner space 45. Gradually reduce, so that the amount of paint can be attached to the gradual adhesion effect. Moreover, the probability that the paint penetrates between the abutting surface 413 and the non-painted surface 121 can be effectively reduced.

Preferably, the outer wall surface 414 has a curved chamfered portion 415 at the bottom end and connected to the pressing surface 413. By the design of the curved chamfered portion 415, the paint penetration into the pressing surface 413 can be further increased. The resistance to the non-painted surface 121 and the adhesion of the paint between the outer wall surface 414 and the surface to be painted 114 can be avoided.

Referring to FIG. 2 and FIG. 6 , the non-painting surface 121 of the painting material 1 is formed with a first positioning hole 123 and a second positioning hole 124. The first positioning hole 123 and the second positioning hole 124 are located on opposite sides, wherein the first The positioning hole 123 is a non-circular hole, and the second positioning hole 124 is a circular hole. The first positioning post 43 and the second positioning post 44 of the upper shielding frame 4 are located on opposite sides, and the first positioning post 43 is a non-circular post having a shape matching the shape of the first positioning hole 123, and the first positioning post 43 is slidable. The first positioning hole 123 is inside. The second positioning post 44 is a circular post having a shape matching the shape of the second positioning hole 124. The second positioning post 44 can be locked in the second positioning hole 124. The first positioning post 43 and the second positioning post 44 are respectively locked in the first positioning hole 123 and the second positioning hole 124, so that the upper shielding frame 4 can be prevented from rotating or shaking relative to the painting material 1 to be painted. The upper shadow frame 4 can be stably positioned on the paint to be painted 1 . It should be noted that, in other design manners, the second positioning hole 124 and the second positioning post 44 may be omitted, so that the upper shielding frame 4 is only stuck to the first positioning of the to-be-painted component 1 through the first positioning post 43. In the hole 123, the positioning effect can also be achieved.

Referring to FIG. 3, FIG. 4 and FIG. 6, the upper magnetic member 5 includes a pressing plate portion 51 for pressing against the carrying wall 42, and a positioning plate portion 52 protruding from the bottom end of the pressing plate portion 51.

In addition, the carrier wall 42 of the upper shadow frame 4 and the upper magnetic member 5 together define a top wall 53 of the upper mask 40 for shielding the non-painted surface 121, whereby spray coating can be prevented from being sprayed onto the non-painted surface 121.

Specifically, the upper mask 40 includes two components of the upper shadow frame 4 and the upper magnetic member 5, and a design manner in which the upper shadow frame 4 and the upper magnetic member 5 are detachably assembled, so that the upper shield is shielded. The frame 4 can be different in size according to the different sizes of the areas of the paint to be painted surface 114 and the non-painted surface 121 of the paint to be painted 1 , and the correspondingly painted and unpainted surface 121 of the paint to be painted 1 of the different styles can be replaced. The upper shield frame 4 is mated with each other, whereby the elasticity of the upper mask 40 in use can be improved. In addition, in other design manners, each of the lower magnetic members 23 of the carrier 2 (as shown in FIG. 5) may be a metal member, and the upper magnetic member 5 may be a magnet, thereby enabling the lower load to be carried. The lower shadow frame 3 of the frame 20 and the upper shadow frame 4 of the upper mask 40 firmly hold the effect of the paint to be painted 1 .

When the paint masking fixture 200 and the paint to be painted 1 are to be assembled, first, the lower shielding frame 3 is sleeved on the substrate portion 211 of the carrier 2 so that the bottom end of the lower shielding frame 3 abuts against the shoulder 213, and the inner circumference The surface 31 abuts against the outer peripheral surface 214. Next, the respective tabs 113 of the paint to be painted 1 are first aligned with the lower cover. The corresponding accommodating groove 311 of the cover frame 3 is placed on the lower shadow frame 3 so that the end surface 112 of the lacquering member 1 abuts against the top edge 32 of the lower shadow frame 3, and the lacquer member 1 is to be painted. The glass plate 12 is abutted against the convex portion 212, and each of the locking pieces 113 is inserted into the corresponding receiving groove 311. Then, the first positioning post 43 and the second positioning post 44 of the upper shielding frame 4 are respectively aligned with the first positioning holes 123 (shown in FIG. 2 ) and the second positioning holes 124 of the painting material 1 (as shown in FIG. 2 ). And superimposing the upper shadow frame 4 on the paint to be painted 1 so that the pressing surface 413 of the elastic pressing wall portion 411 is pressed against the non-painted surface 121 of the paint to be painted 1, and the first positioning post 43 and the first The two positioning posts 44 are respectively locked in the first positioning holes 123 and the second positioning holes 124. Finally, the positioning plate portion 52 of the upper magnetic member 5 is aligned with the positioning groove 421 of the upper shielding frame 4, and the upper magnetic member 5 is placed on the upper shielding frame 4, so that the positioning plate portion 52 is locked in the positioning groove 421. The platen portion 51 is pressed against the carrier wall 42. The magnetic member 5 is adsorbed by the magnetic force of each lower magnetic member 23 (shown in FIG. 5), so that the lower shielding frame 3 of the lower carrier 20 and the upper shielding frame 4 of the upper mask 40 firmly hold the workpiece to be painted 1 And the pressing surface 413 of the elastic pressing wall portion 411 can be brought into close contact with the non-painted surface 121.

Referring to FIG. 3, FIG. 7, FIG. 8 and FIG. 9, FIG. 7 is a flow chart of a method for masking the paint using the paint masking fixture 200 of the embodiment, which comprises the following steps:

Step S1: providing a paint to be painted 1 which comprises a surface to be painted 114 and a non-painted surface 121, and the non-painted surface 121 and the surface to be painted 114 together form a continuous surface.

Step S2: a dimension setting step of pressing the outer wall surface of the wall 41 414 has a height H defined between the abutting surface 413 and the lower surface 423. The outer side of the shielding wall portion 422 further includes an outer end surface 424 connected to the lower surface 423. The lower surface 423 of the shielding wall portion 422 has a length L defined between the outer wall surface 414 and the outer end surface 424, according to the paint to be painted 1 The desired height H size and length L size are selected, and the upper shadow frame 4 of the mask 40 corresponding to the size is selected.

Step S3: the masking step, after the paint to be painted 1 is assembled and positioned in the foregoing manner, the pressing surface 413 of the pressing wall 41 of the upper mask 40 of the paint shielding fixture 200 is pressed against the non-painting paint. Surface 121, and outer wall surface 414 is aligned with contour 122 of non-painted surface 121. The top wall 53 of the upper shroud 40 shields the non-painted surface 121, and the lower surface 423 of the blocking wall portion 422 and the outer wall surface 414 together define a corner space 45. On the other hand, the lower shadow frame 3 of the lower carrier 20 shields the latching piece 113 of the painting material 1 to be painted.

When the painting material 1 is to be painted, the rotary driving mechanism drives the paint shielding fixture 200 and the painting material 1 to be rotated in the direction of the arrow A by the loading platform 2 to perform a horizontal rotation motion. The spray paint sprayed by the spray gun is sprayed on the surface to be painted 114 of the paint to be painted 1 in a direction of arrows I and II at a certain flow rate and flow rate. Since the external environmental space S is not blocked by the shield wall portion 422, the paint is sprayed. The flow rate to be sprayed onto the surface to be painted 114 at the external environmental space S is relatively fast and the flow rate is high. Since the pressure in the corner space 45 is greater than the pressure in the external environment space S, when the paint is sprayed into the corner space 45 via the external environmental space S, the flow rate is reduced and the flow rate is reduced, so that the paint is attached to the surface to be painted 114. The amount of adhesion on the surface is gradually reduced from the external environmental space S toward the corner space 45, so that the adhesion amount of the paint can reach the gradual adhesion effect, and the spray penetration of the paint into the pressing surface 413 and the non-paint surface 121 can be effectively reduced. The probability between the upper shadow frame 4 can achieve a good shielding effect.

After the painting operation of the painting surface 114 is completed, the upper shielding frame 4 is detached from the lacquering member 1 and then the lacquering member 1 is detached from the lower shielding frame 3, and the lacquering member 1 is treated by painting. Remove with 200 for subsequent assembly work.

It should be noted that, in the size setting step of step S2, when the height H dimension of the outer wall surface 414 is set to be large, the pressure in the corner space 45 is reduced, and at this time, adjacent to the pressing surface 413 and the curved shape The amount of paint adhesion at a point P of the joint of the corner portion 415 is increased; conversely, when the height H dimension of the outer wall surface 414 is set small, the pressure in the corner space 45 is increased, and at this time, the paint adhesion at the point P is attached. The amount will decrease. On the other hand, when the length L of the lower surface 423 is set to be large, the pressure in the corner space 45 is increased, and at this time, the amount of paint adhesion at the point P is decreased; on the contrary, when the length L of the lower surface 423 is set to be small. At this time, the pressure in the corner space 45 is reduced, and at this time, the amount of paint adhesion at the point P is increased. By the foregoing sizing method, the paint visor jig 200 can be correspondingly adjusted and set with the height H size and the length L according to the amount of paint adhesion required for the lacquer 1 to be added, so as to increase the application of the paint visor 200. The breadth and flexibility of use.

In summary, the paint masking fixture 200 of the present embodiment is pressed against the paint to be painted 1 by the pressing surface 41 of the upper shielding frame 4 with the pressing surface 413. The non-painted surface 121 can effectively shield the spray paint from spraying onto the non-painted surface 121. And by the pressing wall 41 of the upper shielding frame 4 and the shielding wall portion 422 of the carrying wall 42 , a corner space 45 is defined between the pressing wall 41 and the shielding wall portion 422 , thereby effectively shielding the painting and The amount of paint applied is brought to a gradual adhesion effect. In addition, the paint masking jig 200 has a simple structure and is easy to assemble, and can effectively reduce the manufacturing cost. Furthermore, the paint masking fixture 200 can be correspondingly adjusted and set with the height H dimension and the length L dimension of the shadow frame 4 according to the amount of paint adhesion required for the paint surface 114 to be painted 1 to be added. The breadth of the above and the flexibility of use make it possible to achieve the object of the present invention.

The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
