[0031] As shown in Figures 1 to 6 A clamping positioning jig, comprising a frame 1, the frame 1 has a clamping space 11 inside, the clamping space 11 is used for accommodating a workpiece 2;

[0032] Elastic positioning member 3, at least one side of the frame 1 is provided with the elastic positioning member 3, the clamping end 311 of the elastic positioning member 3 extends into the clamping space 11 to elastically press the workpiece 2 in the frame 1;

[0033] First fixing member 4, at least one side of the frame 1 can be detachably provided with the first fixing member 4, and one side of the workpiece 2 is elastically pressed by the elastic positioning member 3, the other side of the workpiece 2 is elastically pressed by the elastic positioning member 3 or is pressed by the first fixing member 4.

[0034] The clamping positioning jig of the scheme is particularly suitable for the fixation of glass substrate type workpieces 2. Of course, it can also be suitable for the fixation of other workpieces 2 which are easily damaged by clamping or conventional workpieces 2.

[0035] Specifically, the clamping positioning jig of the scheme comprises a frame 1, and the workpiece 2 is fixed in the clamping space 11 of the frame 1 by the elastic positioning member 3. Since the elastic positioning block 31 elastically presses the workpiece 2, the pressing force on the glass substrate type workpiece 2 will not be too large, which can effectively reduce the stress on the glass substrate and avoid damage to the glass substrate due to excessive clamping force.

[0036] To ensure the clamping stability of workpiece 2, this solution also adds a first fixing member 4 to the frame 1, which can also press workpiece 2. In some embodiments, both the upper and lower surfaces of workpiece 2 are pressed by multiple elastic positioning blocks 31, and in some areas of at least one side of workpiece 2, it is optional to additionally set the first fixing member 4 for auxiliary pressing as needed.

[0037] In a more preferred embodiment, one side of the workpiece 2 is pressed by a plurality of elastic positioning blocks 31, and the other side of the workpiece 2 is pressed by a plurality of first fixing members 4, which has a better fixing effect and is less likely to damage the workpiece 2.

[0038] Furthermore, such as Figure 6 As shown, multiple elastic positioning elements 3 are spaced apart on any side of the frame 1; each elastic positioning element 3 includes a positioning block 31, a connecting shaft 32, an elastic element 33, and a guide post 34. The positioning block 31 includes a clamping end 311 and a connecting part 312 with an L-shaped vertical cross section. The end of the connecting part 312 extends horizontally towards the side close to the workpiece 2 to form the clamping end 311. The clamping end 311 is used to abut against the edge of any side of the workpiece 2.

[0039] The connecting part 312 includes a first side arm 3121 and a second side arm 3122. The end of the first side arm 3121 is bent downward to form the second side arm 3122. One end of the connecting shaft 32 is connected to the frame 1, and the other end of the connecting shaft 32 is fitted with the elastic member 33. The end of the elastic member 33 abuts against the inner side of the second side arm 3122. The first side arm 3121 has a movable groove 3123. The guide post 34 is inserted into the movable groove 3123. The bottom end of the guide post 34 is connected to the frame 1, so that when the elastic positioning member 3 elastically presses the workpiece 2, the elastic member 33 is squeezed and the elastic positioning member 3 moves away from the clamping space 11.

[0040] In this embodiment, after the workpiece 2 is placed in the clamping space 11, it is pressed by the elastic positioning member 3. When the side of the workpiece 2 comes into contact with the elastic positioning member 3, a certain force will be generated. Since the frame 1 is connected to the positioning block 31 through the connecting shaft 32 and the elastic member 33, the clamping end 311 will move slightly away from the clamping space 11 after the elastic member 33 is squeezed. When the positioning block 31 moves, it is guided by the guide post 34 and the movable groove 3123, so that the positioning block 31 moves in a straight line and retracts. Therefore, the workpiece 2 is subjected to less force by the elastic positioning member 3 when it is pressed, which can prevent the glass substrate workpiece 2 from being damaged by the fixture.

[0041] The structure of the first fixing member 4 in this scheme is similar to that of the elastic positioning member 3, but it does not have a connecting shaft 32 and an elastic member 33, and only plays a basic clamping role.

[0042] Furthermore, the clamping end 311 includes a first clamping surface 3111 and a second clamping surface 3112, and the included angle between the first clamping surface 3111 and the second clamping surface 3112 is ≥90°.

[0043] In some embodiments, the included angle between the first clamping surface 3111 and the second clamping surface 3112 is 90°. The first clamping surface 3111 of the clamping end 311 is close to the surface of the workpiece 2, and the second clamping surface 3112 is close to the side of the workpiece 2. The edge of either side of the workpiece 2 is pressed against, thereby fixing the workpiece 2.

[0044] In other embodiments, the included angle between the first clamping surface 3111 and the second clamping surface 3112 may be greater than 90°, in which case the edge of any side of the workpiece 2 is pressed against and fixed by the clamping end 311.

[0045] In some specific embodiments, the included angle between the first clamping surface 3111 and the second clamping surface 3112 may be <90°, that is, the first clamping surface 3111 and the second clamping surface 3112 respectively abut against the edges of the upper and lower surfaces of the same side of the workpiece 2 to achieve fixation.

[0046] Furthermore, both the first clamping surface 3111 and the second clamping surface 3112 extend downwards at an angle from the side closest to the clamping space 11 to the side furthest from the clamping space 11. When the elastic positioning member 3 presses against the workpiece 2, the edge of any side of the workpiece 2 can abut against the first clamping surface 3111 or the second clamping surface 3112. In order to ensure that the edge of any side of the workpiece 2 is always abutted against the clamping end 311 without applying excessive pressure to the edge of any side of the workpiece 2, the first clamping surface 3111 and the second clamping surface 3112 in this embodiment are both inclined. When the elastic positioning member 3 is squeezed by the workpiece 2 and retracts to the side furthest from the clamping space 11, the edge of any side of the workpiece 2 slides to a suitable position on the first clamping surface 3111 or the second clamping surface 3112.

[0047] Furthermore, such as Figure 5 As shown, the frame 1 is provided with a plurality of mounting slots 12, and each positioning block 31 is embedded in the corresponding mounting slot 12. The first side arm 3121 is provided with at least two movable slots 3123, and each movable slot 3123 is provided with a guide post 34 connected to the frame 1.

[0048] In this embodiment, first, the positioning block 31 is installed in the mounting groove 12 on the frame 1, preventing the positioning block 31 from shifting left and right on the frame 1, and better stability; then, the guide column 34 is inserted into the movable groove 3123 and connected with the frame 1, since the diameter of the head of the guide column 34 is greater than the width of the movable groove 3123, the elastic positioning piece 3 is limited by the guide column 34 on the frame 1 and cannot move up and down, but can only move forward and backward (i.e. move towards or away from the clamping space 11). In order to ensure better guiding effect, two movable grooves 3123 are provided on the first side arm 3121, and the corresponding guide column 34 is also provided with two, the elastic positioning piece 3 moves along the two movable grooves 3123 at the same time, the moving path is not easy to shift, and the pressing effect on the workpiece 2 is better.

[0049] Further, the frame 1 is also provided with a containing groove 13, and the end of the connecting shaft 32 installed on the frame 1 is located in the containing groove 13. In actual production, the mounting position of the connecting shaft 32 is provided on the frame 1, so that the connecting shaft 32 is located within the range of the frame 1, and the end thereof does not protrude into the clamping space 11.

[0050] Further, the elastic piece 33 is a spring. When the spring is sleeved on the connecting shaft 32 as the elastic piece 33, it still has good elastic deformation ability after being compressed and stretched for many times, so that the elastic positioning piece 3 in the jig has a longer service life and can stably press and fix the workpiece 2.

[0051] Further, the second fixing piece 5 is also included, at least one side of the frame 1 is detachably provided with the second fixing piece 5, the second fixing piece 5 extends into the clamping space 11 and the end thereof abuts against the edge of the workpiece 2.

[0052] In this embodiment, in addition to the elastic positioning piece 3 and the first fixing piece 4 which can respectively press the surface / edge of the workpiece 2, the second fixing piece 5 is also provided to abut against the edge of the workpiece 2, so that the multiple parts of the workpiece 2 can be fixed at the same time, the fixing effect is better, and the workpiece 2 is further prevented from falling off the frame 1. In actual production, 3-4 second fixing pieces 5 can be provided at intervals on each side of the frame 1, or only some of the second fixing pieces 5 can be provided on some sides of the frame 1 according to requirements.

[0053] Further, the top end of the second fixing piece 5 is in the shape of a prism. The top end of the second fixing piece 5 abuts against the edge of the workpiece 2 in the shape of a prism, that is, the part of the top end of the second fixing piece 5 abutting against the workpiece 2 is a plane, and the workpiece 2 is not in point contact, but in relatively larger area contact, so as not to easily cause damage to the edge of the glass substrate workpiece 2.

[0054] Further, the first fixing member 4 and the second fixing member 5 are connected to the frame 1 by bolts. In order to ensure the stability of the connection between the first fixing member 4, the second fixing member 5 and the frame 1, the first fixing member 4 and the second fixing member 5 are preferably bolted to the frame 1, which is relatively stable in connection, and the source and type of the bolts are relatively extensive, and the installation cost is relatively low. In addition, a plurality of bolt holes can be pre-formed on the frame 1, and in the bolt holes at different positions, the first fixing member 4 or the second fixing member 5 can be selected and installed according to the needs to achieve different fixing effects.

[0055] Of course, in other embodiments, other clamping or other fixing methods can be used between the first fixing member 4 and the second fixing member 5 and the frame 1.

[0056] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
