[0003] The mold cavity inside the existing silk screen printing jig is the same size as the glass cover plate, which makes it difficult to take and place the glass cover plate. When the surface printing of the glass cover plate is completed and the glass is taken out, the staff will inevitably touch the printed surface of the glass, which will cause damage to the pattern on the printed surface of the glass cover plate and seriously affect the quality of the surface printing of the glass cover plate. In this regard, we have proposed a jig suitable for silk screen printing on the concave surface of the cover plate. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0027] For example, please refer to Figure 1-6 A jig suitable for screen printing on a concave surface of a cover plate includes a jig body 10, a buffer assembly 50 is connected to both sides of the top of the jig body 10, a fixing plate 20 is connected to the top of the jig body 10, and a contoured scraper 21 is fixed to the bottom of the fixing plate 20;

[0028] The bottom of the jig body 10 is connected to a lifting mechanism 40, and the lifting mechanism 40 includes a rotating motor 41 connected to one side of the bottom of the jig body 10, a bidirectional screw rod 42 connected to the driving end of the rotating motor 41, a fixed block 43 connected to both sides of the bidirectional screw rod 42 and an arm rod 44 rotatably connected to the top of the fixed block 43, the top of the arm rod 44 is rotatably connected to the profiling jig seat 45, the top of the profiling jig seat 45 is connected to the cover plate 30, and one side of the profiling jig seat 45 is connected to the ejection mechanism 70.

[0029] It should be noted that, in the embodiment, the rotating motor 41 drives the bidirectional screw rod 42 to rotate, thereby driving the fixed block 43 to move, and then the arm rod 44 to rotate, thereby driving the profiling fixture seat 45 to rise and fall.

[0030] For example, please refer to Figure 5 The ejecting mechanism 70 includes a rotating rod 71 rotatably connected to one side of the profiling jig seat 45, a first bevel gear 72 connected to the bottom of the rotating rod 71, a second bevel gear 73 meshingly connected to one side of the first bevel gear 72 and a third bevel gear 74 connected to one side of the second bevel gear 73, one side of the third bevel gear 74 is rotatably connected to the profiling jig seat 45, the top of the third bevel gear 74 is meshedly connected to the fourth bevel gear 75, the top of the fourth bevel gear 75 is connected to a limiting rod 76, the outer wall of the limiting rod 76 is slidably connected to a threaded rod 77, and the threaded rod 77 cooperates with the threaded hole of the profiling jig seat 45.

[0031] It should be noted that, in the embodiment, rotating the rotating rod 71 drives the first bevel gear 72 to rotate, thereby driving the second bevel gear 73 and the third bevel gear 74 to rotate, and then driving the fourth bevel gear 75, the limiting rod 76 and the threaded rod 77 to rotate. Since the threaded rod 77 cooperates with the threaded hole, the threaded rod 77 rotates and the threaded rod 77 rises.

[0032] For example, please refer to Figure 2 and Figure 4 , positioning columns 22 are fixed on both sides of the bottom of the fixing plate 20;

[0033] Positioning grooves 11 are provided on both sides of the top of the fixture body 10 , and the groove bodies of the positioning grooves 11 are slidably connected to the positioning posts 22 .

[0034] It should be noted that, in the embodiment, the positioning post 22 enters the positioning groove 11 to limit the position of the fixing plate 20 , thereby preventing the fixing plate 20 from deviating and causing silk screen printing failure.

[0035] For example, please refer to Figure 2 The groove body of the positioning groove 11 is connected to the buffer component 50, and the buffer component 50 includes a spring 51 connected to the groove body of the positioning groove 11 and a buffer plate 52 connected to the top of the spring 51.

[0036] It should be noted that, in the embodiment, the elastic force of the spring 51 provides the buffer plate 52 with space to descend, thereby facilitating the deceleration of the fixing plate 20 .

[0037] For example, please refer to Figure 4 , a plurality of limiting protrusions 451 are fixed on both sides of the bottom of the profiling fixture seat 45;

[0038] A plurality of limiting sliding grooves 12 are provided on both sides of the top of the fixture body 10 , and the groove bodies of the limiting sliding grooves 12 are slidably connected to the limiting protrusions 451 .

[0039] It should be noted that, in the embodiment, the limiting slide groove 12 limits the descending distance of the profiling jig seat 45 , and the limiting protrusion 451 cooperates with the limiting slide groove 12 to enhance the stability of the profiling jig seat 45 .

[0040] For example, please refer to Figure 3 A cavity 452 is provided on the top of the profiling fixture seat 45 , vent holes 453 are provided on both sides of the top of the cavity 452 , and the bottom of the cavity 452 is connected to the air pump 60 .

[0041] It should be noted that, in the embodiment, the air pump 60 absorbs the cover plate through the vent hole 453 to prevent the cover plate from moving.

[0042] For example, please refer to Figure 5-6 , the limiting bars 761 are fixed on both sides of the limiting rod 76;

[0043] Rectangular grooves 771 are provided on both sides of the inner wall of the threaded rod 77 , and the groove body of the rectangular groove 771 is slidably connected to the limiting bar 761 .

[0044] It should be noted that, in the embodiment, the limiting strip 761 cooperates with the rectangular groove 771 to prevent the threaded rod 77 from rotating relative to the limiting rod 76, so that the threaded rod 77 and the limiting rod 76 rotate synchronously.

[0045] The specific operation mode of the utility model is as follows:

[0046] The jig for screen printing on the concave surface of the cover plate is adapted to perform screen printing by lowering the profiling squeegee 21. After the screen printing is completed, the profiling squeegee 21 is raised, and then the bidirectional screw 42 is rotated by the rotating motor 41, thereby driving the fixed block 43 to move, and then rotating the arm 44, thereby driving the profiling jig seat 45 to rise, so that the profiling jig seat 45 is higher than the jig body 10, making it easier for the user to take out the cover plate 30;

[0047] By rotating the rotating rod 71, the first bevel gear 72 is driven to rotate, thereby driving the second bevel gear 73 and the third bevel gear 74 to rotate, and then driving the fourth bevel gear 75, the limiting rod 76 and the threaded rod 77 to rotate. Since the threaded rod 77 cooperates with the threaded hole, the threaded rod 77 rotates and the threaded rod 77 rises, causing one end of the cover plate 30 to tilt up, making it easier for the staff to take out the cover plate 30.

[0048] The above-described embodiments merely represent implementation methods of the present application. However, those skilled in the art will appreciate that variations and modifications may be made without departing from the spirit of the present application, and these modifications are intended to fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
