In specific implementation, the tool fixture is applied to the assembly of display equipment for example, so as to explain the working principle of the tool fixture.

Referring to fig. 1, fig. 2 and fig. 3, the tooling fixture provided by the present invention includes a carrier 11, the carrier 11 includes a first side 101 and a second side 102 adjacent to each other, and the length of the first side 101 is greater than that of the second side 102; the first side 101 is provided with at least one protruding fixing hole 111, and the fixing hole 111 is used for being fixedly connected with a first workpiece; and the positioning piece 12, the positioning piece 12 is connected with the carrier plate 11 through a fastener 30, and the positioning piece 12 is used for abutting against the edge of the second workpiece.

The first workpiece in this embodiment may be a back plate 21 in a display device, and the second workpiece is a COF plate 22. The back plate 21 comprises a front surface and a back surface which are opposite, the liquid crystal glass covers the front surface of the back plate 21, the COF plate 22 needs to be fixed on the back surface of the back plate 21, and the COF plate 22 is connected with the liquid crystal glass through a COF line. The back surface of the back plate 21 is provided with hanging avoiding columns.

When the tool fixture is used, the fixing hole 111 of the tool fixture is penetrated through the wall-hung column to fixedly connect the tool fixture with the back plate 21. The length of the first side 101 and the length of the second side 102 of the carrier 11 (or the length and the width of the carrier 11) can be configured according to the size of the back plate 21. The positioning element 12 extends to the side of the back plate 21 along the direction of the second side 102 of the carrier plate 11, and the direction is taken as the length direction of the positioning element 12, and the length of the positioning element 12 can be set according to actual requirements. Specifically, the positioning element 12 is used to abut against the edge of the COF board 22, so as to ensure that the COF line is positioned just in the middle of the safety gap between the front shell 23 and the back plate 21 along the front edge of the positioning element 12 away from the carrier board 11 when the COF board 22 is fixed. Then, to the COF board 22 of the same model, hang this frock tool on backplate 21 earlier, later directly fix COF board 22 along the forward position parallel and level of setting element 12 just can ensure that the COF line of being connected with COF board 22 is located safety clearance's centre, can avoid from this when fixed COF board 22, need make a round trip to adjust COF board 22's position, and then improved COF board 22's fixed speed, realize COF board 22's quick location, improve assembly efficiency.

In some embodiments, referring to fig. 4, the positioning element 12 includes a fixing portion 121 and a positioning portion 122, one end of the fixing portion 121 is connected to the carrier plate 11 through the fastening element 30, the other end of the fixing portion 121 is connected to one end of the positioning portion 122, the other end of the positioning portion 122 is used for abutting against a first workpiece, and the middle portion of the positioning portion 122 is used for abutting against a second workpiece.

The fixing portion 121 and the positioning portion 122 are connected to form an L-shape. Considering that the back surface of the back sheet 21 is convex, the edge of the fixed COF sheet 22 is concave with respect to the central convex portion. Therefore, if the carrier 11 is fixed to the rear convex portion of the back plate 21 through the fixing holes 111, the positioning element 12 extends to the concave portion along the direction of the second side edge 102; then, in order to achieve a better spacing effect, the positioning member 12 is provided in an L shape including the fixing portion 121 and the positioning portion 122, and it is ensured that one end of the positioning portion 122 is connected to the fixing portion 121, and the end of the other end of the positioning portion 122 abuts against the recessed portion of the back plate 21. At this time, it can be understood that the positioning portion 122 is perpendicular to the plane of the back plate 21. When the COF board 22 is fixed, the COF board 22 is directly disposed along the positioning portion 122, and after the fixing, the COF board 22 abuts against the positioning portion 122, so that the fixing accuracy of the COF board 22 can be improved.
