[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Depend on Figures 1-4 This utility model relates to a bonding fixture for electronic shelf label ink screens and PCBA boards, including a bonding fixture 1. The bonding fixture 1 includes a fixture body 101. The fixture body 101 has a lower positioning groove 102 inside, and an upper positioning groove 103 is formed at the top of the lower positioning groove 102. The shape of the lower positioning groove 102 is formed according to the shape of the electronic shelf label ink screen, and it is used to position the electronic shelf label ink screen. The shape of the upper positioning groove 103 is formed according to the shape of the PCBA board, and it is used to position the PCBA board. A clamping and mounting component 2 is connected to one end of the fixture body 101, and a support component 3 is formed at the top of the other end of the fixture body 101.

[0024] The clamping and mounting assembly 2 includes a horizontal plate 201 positioned above the fixture body 101. A groove 203 is formed on the horizontal plate 201, and two sliders 204 are symmetrically slidably mounted inside the groove 203. Pressure rollers 205 are mounted at the bottom ends of the sliders 204. A pressure plate 206 is positioned above the horizontal plate 201, and two connecting rods 207 are symmetrically hinged to the bottom ends of the pressure plate 206. The bottom ends of the two connecting rods 207 are respectively hinged to the two sliders 204, forming a V-shape. Guide rods 208 are symmetrically mounted at the top of the horizontal plate 201, and the pressure plate 206 is slidably connected to the guide rods 208. A limiting plate 209 is fixedly mounted at the top of the guide rods 208, and the limiting plate 209 is located on the pressure plate 201. Above 06, springs 210 are symmetrically installed at the bottom of the pressure plate 206. The bottom of the springs 210 is fixedly connected to the horizontal plate 201. A side plate 211 is installed at one end of the fixture body 101. A rotating seat 212 is installed on the side plate 211. A connector 202 is installed at the end of the horizontal plate 201 near the side plate 211. The connector 202 is rotatably connected to the rotating seat 212. The fixture body 101 is provided with a lower positioning groove 102 and an upper positioning groove 103 for overlapping placement of the electronic price tag ink screen and the PCBA board, which facilitates the positioning and installation of the electronic price tag ink screen and the PCBA board. At the same time, the electronic price tag ink screen and the PCBA board on the upper and lower sides are pressed by two pressure rollers 205, which facilitates adhesion and fixation.

[0025] The support assembly 3 includes a fixed plate 301 symmetrically installed on the top of the end of the fixture body 101 away from the side plate 211. A receiving box 302 is fixedly installed on the side of the two fixed plates 301 that are away from each other. A support plate 303 is slidably installed inside the receiving box 302. The bottom wall of the horizontal plate 201 presses on the support plate 303 to keep the horizontal plate 201 horizontal. A pull rod 304 is fixedly installed on the end of the support plate 303 near the receiving box 302. One end of the pull rod 304 extends to the outside of the receiving box 302. When the bottom wall of the horizontal plate 201 contacts the support plate 303, the horizontal plate 201 is horizontally positioned above the fixture body 101, which facilitates the pressing of the electronic price tag ink screen and the PCBA board. At the same time, the horizontal plate 201 is rotatably connected to the rotating base 212, so that the horizontal plate 201 can be rotated upward to open, which facilitates the placement of the electronic price tag ink screen and the PCBA board inside the fixture body 101.

[0026] Working principle: When in use, firstly, during positioning, since the horizontal plate 201 is rotatably connected to the rotating seat 212 on the side plate 211 through the connector 202, at this time, rotating the horizontal plate 201 will open the horizontal plate 201 upward, exposing the fixture body 101. Then, pulling the two pull rods 304 will move the support plate 303 into the receiving box 302.

[0027] Then, an electronic price tag ink screen is placed in the lower positioning groove 102 inside the fixture body 101. The shape of the lower positioning groove 102 is adapted to the shape of the electronic price tag ink screen. Then, an adhesive layer is applied to the electronic price tag ink screen. Then, a PCBA board is placed in the upper positioning groove 103. The shape of the upper positioning groove 103 is adapted to the shape of the PCBA board. After both are placed inside the fixture body 101, the electronic price tag ink screen and the PCBA board are tightly attached.

[0028] Then, the support plate 303 inside the housing 302 is pushed outward, and then the horizontal plate 201 is rotated so that the bottom wall of the horizontal plate 201 contacts the support plate 303 to support the horizontal plate 201 and make it horizontal. At this time, the bottom walls of the two pressure rollers 205 contact the top wall of the PCBA board, and then the pressure plate 206 is pushed downward. Then, the two pressure rollers 205 are pushed along the slide groove 203 to move away from each other through the two connecting rods 207, pressing the electronic price tag ink screen and the PCBA board together to make them bonded and installed. Finally, the horizontal plate 201 is opened upward to remove the bonded workpiece.
