Fig. 1 and 2 show a product 10 that requires topical application. In this embodiment, the product 10 may be a television housing, and it should be understood that the product to which the local spraying jig provided by the present invention is applied is not limited to a television housing, and any product that needs to be locally sprayed falls within the protection scope of the present invention. Referring to fig. 2, in order to realize the local spraying, a method is generally adopted to provide a boundary line 100 on the product 10 as a boundary between the spraying area 101 and the non-spraying area 102 of the product 10, and a boundary groove 100 (also called a process groove) may be provided as a boundary line in the prior art. When the partial painting is performed, masking tape is stuck along the boundary line 10 to the non-painting area 102 of the product 10 to separate the painting area 101 and the non-painting area 102. However, the method wastes resources, cannot ensure the production quality, and has lower production efficiency.
To solve the above problems, the present invention provides a local spraying jig, and fig. 3 to 10 are schematic views of an embodiment of the local spraying jig provided in the present invention. Referring to fig. 3 to 5, the local spraying jig includes a mounting base 1, a shielding cover 2 and a pressing bar 30. The mounting 1 carries and mounts the product 10 to be sprayed. The hood 2 is movably arranged above the mounting 1 such that the hood 2 has a covering position covering the non-painting area 102 of the product 10 and an open position which is open such that the product 10 can be taken out. In this embodiment, in order to facilitate opening, the hood 2 may further include a handle 23. The pressing strip 30 is disposed on the periphery of the mask 2, and includes a pressing edge 31, where the pressing edge 31 is used to at least partially separate the spraying area 101 and the non-spraying area 102 of the product 10 corresponding to the dividing line 100 on the product 10 when the mask 2 is in the covering position.
The mode that the screening cover 2 is movably arranged on the mounting seat 1 can be various, for example, the screening cover can be in sliding connection, rotating connection or detachable connection, and the product 10 can be screened only when spraying is carried out, and the product 10 can be taken out after spraying is finished. In this embodiment, one end of the spray shelter 2 is provided with a connecting plate 22, and is hinged to the mounting base 1 through the connecting plate 22, so as to realize the rotary connection with the mounting base 1. At this time, the pressing bar 30 is disposed at a free end of the shield 2 opposite to the connecting plate 22, so that the product 10 can be taken out when the shield 2 is rotated to be opened to the opened position, and the pressing edge 31 of the pressing bar 30 corresponds to the dividing line 100 when the shield 2 is rotated to be closed to the cover position.
It should be noted that the boundary line 100 may be a boundary groove 100 (or a process groove) which has no solid structure and is used only for distinguishing the boundary between the painted area 101 and the non-painted area 102, or may be a boundary groove 100 (or a process groove) which is provided along the boundary between the painted area 101 and the non-painted area 102 for convenience of operation, in this embodiment, the boundary line 100 is formed by the boundary groove 100, and the pressing blade 31 is inserted into the boundary groove 100 when the mask 2 is in the covering position.
Referring to fig. 6, when the partial spray coating jig is used for spraying, the product 10 to be sprayed is fixed to the mounting base 1, and the shielding cover 2 is closed, so that the pressing blade 31 is inserted into the boundary groove 100 of the product 10 (i.e., corresponds to the boundary line 100 of the product 10). At this time, the shielding cover 2 covers the non-spraying area of the product 10, and the pressing blade 31 separates the spraying area 101 and the non-spraying area 102 of the product 10, and in some embodiments, if the pressing blade 31 only partially separates the spraying area 101 and the non-spraying area 102, it is further required to stick a masking paper on the non-spraying area 102 where the product 10 is still exposed, so that only the spraying area 101 of the product 10 is exposed, and then the spraying operation is performed. The spraying area 101 and the non-spraying area 102 of the product 10 are separated by the reusable pressing blade 31, and the adhesive tape is not adhered manually, so that the consumption of the adhesive tape is reduced, the spraying quality is ensured, and the production efficiency is improved.
Further, the pressing bar 30 is detachably attached to the hood 2. In this way, the bead 30 can be replaced when the bead 30 needs to be replaced (for example, when the bead 30 is contaminated due to multiple spraying or when the boundary line changes and the pressing edge 31 needs to be adjusted accordingly).
Preferably, referring to fig. 7 and 8, the length direction of the pressing bar 30 is a horizontal direction, at least one side of the spray hood 2 is provided with a mounting sleeve 33 extending along the horizontal direction, a yielding hole 330 extending along the horizontal direction is formed in a side wall of the mounting sleeve 33, the pressing bar 30 includes a pressing bar body 32 extending along the horizontal direction, the pressing blade 31 is arranged along the length direction of the pressing bar body 32 and extends downward from the pressing bar body 32, the pressing bar body 32 is sleeved in the mounting sleeve 33, and the pressing blade 31 extends out of the mounting sleeve 33 from the yielding hole 330. So that the dividing slot 100 of the product 10 can be inserted when the screening can 2 is in the covering position, and the separation of the painting zone 101 from the non-painting zone 102 is achieved.
Further, referring to fig. 7, a limiting hole 333 is formed in a side wall of the mounting sleeve 33, and a limiting pin 34 is inserted into the mounting sleeve 33 from the limiting hole 333 and abuts against the molding body 32 to limit the molding body 32 and the mounting sleeve 33 from sliding in a transverse direction. In this embodiment, the limiting hole 333 is disposed at an end side of the mounting sleeve 33 and located at an outer end of the molding main body 32, so that when the limiting pin 333 is inserted into the mounting sleeve 33, the limiting pin abuts against the outer end of the molding main body 32, so as to limit the sliding of the molding main body 32. In this way, the limit pin 333 applies only an axial force to the bead 32, thereby preventing the bead body 32 from being deformed.
When the pressing strip 30 is installed, the limiting pin 34 at one end of the installation sleeve 33 is firstly taken out, the pressing strip body 32 is sleeved into the installation sleeve 33 along the transverse direction, at the moment, the pressing blade 31 extends out of the installation sleeve 33 from the position yielding opening 330, and after the pressing blade is sleeved in place, the limiting pin 34 is inserted to limit the relative sliding between the pressing strip body 32 and the installation sleeve 33. When the pressing strip 30 needs to be disassembled, the limiting pin 34 is taken out, and the pressing strip 30 can transversely slide out.
Further, the cross section of the bead body 32 is square, the mounting sleeve 33 is a square tube matched with the bead body 32, and is formed by enclosing an upper folding plate 331 and a lower folding plate 332, the cross section of the upper folding plate 331 and the cross section of the lower folding plate 332 are both L-shaped, the upper folding plate 331 and the upper side of the lower folding plate 332 are connected with each other (including but not limited to screw connection), the lower side end of the upper folding plate 331 and the lower side end of the lower folding plate 332 are arranged at intervals to form the let position opening 330, the upper folding plate 331 is further provided with a connecting structure 3 (including but not limited to mounting holes, mounting screws and the like) for connecting with the mask cover 2, so as to mount the mounting sleeve 33 to the mask cover 2. In this way, on the one hand, the mounting sleeve 33 can be easily manufactured, and on the other hand, the circumferential limitation between the bead body 32 and the mounting sleeve 33 can be realized depending on the shape of the two, so that the pressing blade 31 is prevented from being deformed due to the abutment between the pressing blade 31 and the side wall of the mounting sleeve 33.
Preferably, in this embodiment, the mounting sleeve 33 is formed by machining a steel material, which has the advantages of being easy to machine and durable. The pressing strip 30 is formed by extruding aluminum and has the advantages of easy guarantee of straightness, smooth surface, difficulty in rubbing products and easiness in forming. In order to be able to adapt to the corresponding dividing line 100, when the dividing line 100 is arranged linearly, the requirement on the straightness of the mounting sleeve 33 and the bead 30 is high, and preferably, the straightness of the mounting sleeve 33 is less than 0.3mm, and the straightness of the bead 30 is less than 0.2 mm.
Further, in order to avoid scratching the inner wall of the boundary groove 100, the pressing blade 31 is sized to: when the shielding cover 2 is in the covering position, the pressing blade 31 is inserted into the dividing groove 100 of the product 10 and spaced from the inner wall of the dividing groove 100. For example, when the boundary groove 100 has a rectangular cross section, the thickness of the pressing blade 31 is set to be smaller than the width of the boundary groove 100, and the length of the pressing blade 31 inserted into the boundary groove 100 is set to be smaller than the depth of the boundary line 100. Preferably, the width of the pressing blade 31 is 0.1-0.2mm smaller than that of the process tank 100, and the lower end of the pressing blade 31 is 0.1-0.2mm away from the bottom of the process tank 100. (for example, when the dividing line 100 is 0.8mm wide, the thickness of the pressing edge 31 is 0.6 mm). Further, the end face of the lower end of the pressing blade 31 is arranged in an arc line, so that the product 10 can be effectively prevented from being scratched, and therefore marks are prevented from being left on the product 10.
Further, in the first embodiment, the pressing blade 31 is linearly disposed, and since the dividing groove 100 extends downward on both sides of the product, the pressing blade 31 cannot cover the side of the product 10. In this case, it is necessary to attach a masking paper to the corresponding part of both sides of the product 10 to isolate the side surface which is not covered by the pressing blade 31. The pressing edge 31 has the advantages of convenient production and difficult deformation.
In the second embodiment, both ends of the pressing blade 31 in the transverse direction are protruded downward to cover the side of the product, and at this time, the pressing blade 31 can cover the side of the product, thereby avoiding the use of the masking tape, but such a pressing blade 31 has a complicated shape, a more complicated molding process, and is easily deformed, and has a shorter service life than the straight pressing blade 31.
It will be appreciated by those skilled in the art that since the shape of the dividing line 100 may be varied, the pressing edge 31 is disposed parallel to the dividing line 100 to accommodate different shapes of the dividing line 100, so long as it is possible to achieve full separation of the non-sprayed region 102 and the sprayed region 101 of the product 10, avoiding the additional use of sticker separation.
Further, referring to fig. 3, the mounting base 1 includes a supporting member 11 and a bottom mold 12, the supporting member 11 is used for supporting the spray hood 2, and the bottom mold 12 is detachably mounted on the supporting member 11. The bottom die 12 is provided with a fixing position for embedding the product 10, and preferably, the bottom die 12 is a concave die matched with the product 10. Preferably, the bottom mold 12 is made of bakelite board, so as to avoid scratching the product 10. Therefore, the product 10 to be sprayed can be mounted on the mounting seat 1 after being mounted on the bottom die 12, and the operation is simpler and more convenient. After the spraying is finished, the product 10 and the bottom die 12 can be taken out together, so that the product 10 is prevented from being contacted with the undried paint.
Preferably, the supporting member 11 may be formed by combining aluminum profiles or welded by steel pipes, and mainly plays a role in supporting the bottom mold 12 and the covering assembly 2, and the covering hood 2 may be made of iron sheet through bending. The local spraying jig is simply manufactured, and cost is saved.
Further, die block 12 is equipped with spacing arch 121 upwards, the hiding and spraying cover 2 be equipped with spacing breach 21 that spacing arch 121 corresponds, spacing arch 121 with spacing breach 21 is used for the hiding and spraying cover 2 butt when being in the shroud position, make pressure sword 31 in from top to bottom direction interval in product 10. Thus, in this embodiment, when the shielding cover 2 rotates to the cover lid position, the pressing strip 301 is just inserted into the dividing groove 100, and has a certain distance (preferably 0.1-0.2mm) from the bottom of the dividing groove 100, so as to prevent the pressing edge 31 from rubbing and scraping the product 10. Preferably, two limiting protrusions 121 are arranged and are respectively positioned on two sides of the product 10, and two limiting notches 21 are arranged on the shielding cover 2 and correspond to the two limiting protrusions 121.
For the convenience of understanding, the following description is made in conjunction with the whole process of spraying by using the local spraying jig provided in the present embodiment. The method for spraying by adopting the local spraying jig provided by the embodiment can comprise the following steps:
s1, mounting the pressing bar 30 on the canopy 2;
s2, rotating the screen 2 to the open position, and mounting the product 10 to be painted to the mounting base 1;
