Referring to fig. 1, fig. 2 and fig. 3, the tooling fixture of the present invention includes a carrier plate 11, the carrier plate 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 adapted according to the size of the back plate 21. The positioning element 12 extends towards 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 the backplate 21 earlier, later directly fix the COF board 22 along the leading edge parallel and level of setting element 12 just can ensure that the COF line that is connected with COF board 22 is located the centre of safety clearance, can avoid when fixed COF board 22 from this, need make a round trip to adjust the position of COF board 22, 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 plate 21 is convex, the edge of the fixed COF board 22 is concave with respect to the central convex portion. Therefore, if the carrier plate 11 is fixed on the convex portion of the back surface of the back plate 21 through the fixing hole 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.

In some embodiments, referring to fig. 5, the positioning element 12 further includes a bending portion 123, the bending portion 123 is connected to the other end of the positioning portion 122, and the bending portion 123 is used for abutting against the first workpiece. Specifically, the bent portion 123 may be opposite to the fixing portion 121, and the provision of the bent portion 123 increases the contact area between the other end of the positioning portion 122 and the back plate 21, so as to prevent the end of the positioning portion 122 from scratching the back plate 21 when the back plate 21 contacts, thereby improving the reliability of the tooling fixture.

As an embodiment, please refer to fig. 2, a sliding slot 1211 is disposed on the fixing portion 121, and the fastening member 30 connects the fixing portion 121 with the carrier 11 through the sliding slot 1211. The number of the sliding grooves 1211 can be one or two in parallel; the fastener 30 connects the positioning member 12 with the carrier plate 11 through the sliding slot 1211. In this embodiment, the slide slot 1211 is provided, so that the positioning member 12 can slide along the slide slot 1211. The direction of the sliding slot 1211 is parallel to the line of the first side 101 of the carrier plate 11, that is, the positioning element 12 can slide in a direction perpendicular to the carrier plate 11. Because of the display device to different models, the model of COF board 22 also has the difference, sets up setting element 12 as can sliding, and the position that is equivalent to location portion 122 can remove along the direction of second side 102, ensures that this frock tool can the assembly of the COF board 22 of different models, improves range of application.

Specifically, referring to fig. 6, the carrier 11 is provided with a plurality of positioning holes 112, and the fastening member 30 is disposed through the sliding slot 1211 and the positioning holes 112 to fix the fixing portion 121 to the carrier 11.
