[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1-3 A new and improved die-cutting assembly jig is shown, comprising a jig body 1 and a positioning plate 2. The jig body 1 is a rectangular box made of aluminum alloy or hard plastic. A vacuum chamber is provided inside the jig body 1. A suction hole 11 connected to the vacuum chamber is provided on the side of the jig body 1. A quick connector 3 is installed at the suction hole 11. The quick connector 3 is connected to a negative pressure generating device through a pipeline and a control valve. Preferably, the negative pressure generating device is a vacuum pump.

[0019] like Figure 1 , Figure 3 As shown, a rectangular placement groove 12 is provided on the top of the fixture body 1, and a vacuum hole 13 connected to the vacuum chamber is provided at the bottom array of the placement groove 12. When the control valve is opened, the negative pressure generating device forms a negative pressure in the vacuum chamber, thereby forming an adsorption force at the vacuum hole 13.

[0020] like Figure 1-3As shown, the positioning plate 2 is a rectangular plate that matches the placement groove 12, and the thickness of the positioning plate 2 is equal to the depth of the placement groove 12. An L-shaped component groove 21 is opened at the center of the upper surface of the positioning plate 2, and an L-shaped die-cutting hole 22 is opened at the bottom of the component groove 21. The die-cutting hole 22 is located in the center of the component groove 21, and the depth of the die-cutting hole 22 is less than the thickness of the die-cutting piece (not shown).

[0021] Two positioning pins 23 are fixed at one end of the bottom of the component slot 21, and a positioning hole that matches the positioning pin is opened on the component (not shown). When in use, the die-cutting piece is first placed in the die-cutting piece hole 22, and the negative pressure generating device is turned on to fix the die-cutting piece; then the positioning hole of the component is put on the positioning pin 23 to put the component into the component slot 21.

[0022] like Figure 1-3 As shown, a plurality of through holes 24 are also provided at the bottom of the component slot 21 , and the plurality of through holes 24 are evenly distributed around the die-cut hole 22 , and the positions of the through holes 24 correspond to the positions of the vacuum holes 13 on the jig body 1 , so that the vacuum holes 13 can adsorb the components through the through holes 24 .

[0023] Preferably, circular avoidance positions 14 are provided at the four corners of the placement groove 12 to facilitate the removal of the positioning plate 2 from the placement groove 12. A silicone layer is applied to the edge of the bottom of the positioning plate 2 to prevent vacuum leakage from causing unreliable adsorption.

[0024] The working principle of the embodiment of the present application is as follows:

[0025] First, select the required positioning plate 2 according to the needs and place the positioning plate 2 in the placement groove 11 of the fixture body 1;

[0026] Then the die-cut piece is placed in the die-cut piece hole 22 and the component is placed in the component slot 21;

[0027] Then, the negative pressure generating device is turned on to press the component tightly with the die-cut part;

[0028] Finally, the negative pressure generating device is turned off and air is blown to break the vacuum, so that the assembled die-cut components are blown out of the positioning plate 2.

[0029] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0030] By setting through holes connected to the vacuum holes around the die-cut holes, the components can be adsorbed and squeezed on the die-cut parts, so that the die-cut parts and the components can be closely fitted, avoiding poor adhesion caused by manual pressing and leakage.

[0031] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
