The above described features and advantages of the present invention will be more apparent from the following description.

1 is an exploded perspective view of an assembly jig, a first workpiece, and a second workpiece according to an embodiment of the present invention. Referring to FIG. 1 , the assembly jig 100 is adapted to attach a first workpiece 10 to a second workpiece 20 . In the present embodiment, the first workpiece 10 is, for example, a bezel of a screen of a notebook computer, and the second workpiece 20 is, for example, a glass of a screen. For convenience of description, the following description will be made by replacing the first workpiece and the second workpiece with the frame 10 and the glass 20, respectively, but not limited thereto. In addition, a glue 30 is disposed on the glass 20 for fitting the frame 10, for example.

The assembly jig 100 includes a base 110, a plurality of elastic positioning members 120, a pneumatic cylinder 130, and a press-fit fixing block 140. The base 110 has a bottom plate 112 and a plurality of side walls 114 connected to each other. The bottom plate 112 and the side walls 114 constitute a processing space P. The processing space P is adapted to accommodate the glass 20, and each of the side walls 114 has at least one receiving hole 114a.

The elastic positioning members 120 are respectively disposed in the receiving holes 114a and protrude from the processing space P in a normal state. In detail, each of the elastic positioning members 120 includes, for example, a spring 122 and a ball 124. The spring 122 is disposed in one of the receiving holes 114a. The ball 124 is coupled to the spring 122, and the ball 124 protrudes at least partially in the processing space P at least partially. In addition, the elastic positioning members 120 are detachably disposed in the receiving holes 114a for the user to replace the springs 122 with different elastic coefficients. In addition, in an embodiment not shown, the elastic positioning members 120 may be integrally formed of an elastic material, but are not limited thereto.

The pneumatic cylinder 130 is disposed toward the processing space P. The press-fit block 140 is coupled to the pneumatic cylinder 130 and is located between the pneumatic cylinder 130 and the base 110. The pneumatic cylinder 130 is used to drive the pressing and fixing block 140 to move toward or away from the base 110. In addition, in the embodiment, the assembly jig 100 further includes a cushioning member 150 disposed between the pressing and fixing block 140 and between the pressing and fixing block 140 and the base 110. For example, the material of the cushioning member 150 may be rubber or a foamed material or the like.

2A-2E are flow charts of assembling the glass and the frame of FIG. 1 by assembling the jig. Referring first to FIGS. 2A and 2B, the glass 20 is placed in the processing space P. Referring to FIG. 2B and FIG. 2C , the user can apply a pressure to move the glass 20 to the bottom plate 112 , so that the glass 20 and the elastic positioning member 120 structurally interfere. During the structural interference of the glass 20 with the elastic positioning member 120, the glass 20 abuts against the elastic positioning members 120. That is to say, the glass 20 will abut against the balls 124, so that the balls 124 press the springs 122 to compress and deform, and move the balls 124 into the accommodating holes 114a.

It is worth mentioning that after the glass 20 abuts against the elastic positioning members, the glass 20 can be positioned at a predetermined position of the base 110, which is quite convenient. In addition, since the tolerances of the different batches of the bezel 10 and the glass 20 may be different, it may be necessary to change the predetermined position of the glass at the base 110. When the predetermined position of the glass 20 at the base 110 is to be changed, it is only necessary to replace the springs 122 of different spring constants, which is very elastic in use.

In addition, in the embodiment, the assembly jig 100 further includes a protective layer (not shown) disposed on the bottom plate 112 and located in the processing space P. The material of the protective layer is, for example, Teflon rubber, and can be disposed on the bottom plate 112 in a coating manner. In this way, when the glass 20 is disposed in the processing space P, the glass 20 can be separated from the bottom plate 112 by the isolation of the protective layer, thereby preventing the glass 20 from being scratched.

Next, referring to FIG. 2C and FIG. 2D, the bezel 10 is placed in the processing space P. In detail, the assembly jig 100 further includes a plurality of limiting members 160 respectively disposed on the sidewalls 114 and located in the processing space P. In terms of the relative position, the limiting members 160 are away from the bottom plate 112 relative to the elastic positioning members 120 for limiting the position of the frame 10 . The bezel 10 can be adapted between the limit members 160. When the bezel 10 is placed in the processing space P, the bezel 10 contacts and abuts against the limiting members 160 without directly contacting the glass 20. In the present embodiment, the stoppers 160 are made of, for example, a cushioning material such as rubber or foamed material, and the frame 10 can be prevented from being modified. In another embodiment not shown, the limiting members 160 may also be omitted, and the positions of the frames are limited by the side walls 114.

Referring to FIG. 2D and FIG. 2E , the pneumatic cylinder 130 drives the pressing and fixing block 140 to move toward the bottom plate 112 along a first direction D1 , so that the pressing and fixing block 140 abuts against the frame 10 by the cushioning member 150 to make the frame. 10 and the glass 20 are bonded together by a backing 30 disposed between the two.

In the present embodiment, the pneumatic cylinder 130 can press the frame 10 and the glass 20 in a two-stage manner. In detail, the first stage is that the air cylinder 130 drives the frame 10 close to the glass 20, and the operator can confirm whether the alignment of the frame 10 and the glass 20 is correct at this time. If there is a misalignment, the springs 122 of different elastic coefficients may be replaced as needed to change the relative position of the glass 20 and the bezel 10. After the positioning is confirmed, the second stage of pressing is performed. At this time, the pneumatic cylinder 130 continues to move the pressing and fixing block 140 in the direction of the bottom plate 112 in the first direction D1, so that the frames 10 and 20 are surely joined by the adhesive 30 therebetween. Since the glass 20 cannot be re-engaged with the frame 10, the above two-stage press-fitting can reduce the joint failure caused by the incomplete positioning, that is, the engagement.

Figure 3 is a top plan view of a portion of the assembly of Figure 2C. Referring to FIG. 3 , in the embodiment, the number of the elastic positioning members 120 is, for example, eight, and is symmetrically disposed on each of the side walls 114 . Although the present embodiment is exemplified by the eight elastic positioning members 120, the number and position of the elastic positioning members 120 may be adjusted by the engineer, and is not limited thereto.

In summary, the positioning jig and the assembly jig of the present invention can conveniently and accurately position the relative positions of the first workpiece and the second workpiece by providing an elastic positioning member on the side wall of the base. Thereby, the problem of the offset caused by the manual positioning can be avoided, and the first workpiece and the second workpiece can be assembled quickly and efficiently. In addition, when facing the male parts with different tolerances, it can also be adjusted by replacing the elastic positioning members with different elastic coefficients, which is quite elastic in use.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
