[0034] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0035] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0036] The traditional method of fixing the needle membrane is to fix the required needle membrane on the support plate by a gland, and then tighten the gland by screws to complete the installation of the needle membrane. Limited by the equipment space and the number of fixed parts, the equipment changeover time is about 2 hours each time, which greatly affects the work efficiency. Based on this, the utility model discloses a needle membrane quick disassembly and assembly mechanism, which can quickly replace different types of needle membranes, reduce the changeover time and improve efficiency.

[0037] See also Figures 1 to 4 As shown, the needle membrane quick disassembly and assembly mechanism includes a first component and a second component.

[0038] like Figure 1 and Figure 2 In the present application, the first component and the second component are opposite to each other in the second direction (Z-axis direction), and the two components can be close to or far away from each other, so as to cooperate with the power-on detection of the electronic paper product.

[0039] Combination Figure 3 and Figure 4 As shown, both the first component and the second component include a guide groove block 1, a needle membrane fixing plate 2 and a ball screw 3. Among them, slots 11 are provided on both sides of the guide groove block 1, the needle membrane fixing plate 2 is arranged in the slots 11 along the first direction (Y-axis direction), positioning grooves 21 are provided on both sides of the needle membrane fixing plate 2, and the ball screw 3 is provided on both sides of the guide groove block 1 and matches and corresponds to the positioning groove 21, and the ball screw 3 is used to fix the needle membrane fixing plate 2 in place.

[0040] In this application, the needle film fixing plate 2 of the first component is provided with an upper needle film 4, and the needle film fixing plate 2 of the second component is provided with a lower needle film 5. By controlling the positions of the first component and the second component, the upper needle film 4 and the lower needle film 5 can be moved closer to or farther from each other along the second direction, so as to conduct a lighting test on the electronic paper product. For different models of electronic paper products, the tester only needs to pull out the existing needle film fixing plate 2 together with the upper needle film 4 / lower needle film 5 from the guide groove block 1, and insert the new film fixing plate together with the adapted upper needle film 4 / lower needle film 5 into the guide groove block 1 for fixing.

[0041] The above mechanism can quickly and effectively fix or remove the required needle membrane by combining the guide groove block 1 with the ball screw 3 and inserting and installing the needle membrane fixing plate 2, thereby shortening the equipment changeover time to about 20 minutes each time, thereby reducing the changeover time and improving efficiency, and also reducing the safety hazards of operators lying down for a long time to operate inside the equipment.

[0042] In addition, the overall structure of the mechanism is simplified and easy to operate. The guide groove block 1 can pull the upper needle membrane 4 / lower needle membrane 5 in / out along the first direction without deviation, ensuring the accuracy of the position, so that it can be reliably matched with the electronic paper product to be tested. The ball screw 3 can position and fix the needle membrane fixing plate 2 after it is in place through elastic resistance, thereby ensuring the stability of the upper needle membrane 4 / lower needle membrane 5.

In the present application, the linear drive 7 is preferably a cylinder. In some other embodiments, it can also be replaced by a device that can provide linear thrust, such as an electric push rod, a servo linear module, etc.

[0045] Furthermore, the needle membrane quick disassembly and assembly mechanism also includes a distance sensor 8, which is used to detect the moving stroke of the first component and / or the second component, and can feed back the detection data to the processing system of the equipment, and then control the driving stroke of the linear drive 7 to prevent problems such as over-travel collision.

[0047] In some embodiments, the cross-section of the slot 11 is one of U-shaped, T-shaped, dovetail-shaped, and circular-shaped, so as to achieve better anti-slip and guiding effects and ensure the installation effect of the needle membrane fixing plate 2.

[0048] In some embodiments, the number of ball screws 3 on each side of the guide slot block 1 is 2 to 4, so as to improve the stability of the needle membrane fixing plate 2 after installation. Figure 3 As shown, in the present application, there are two ball screws 3 on each side of the guide slot block 1 .

[0049] See also Figure 4 As shown, in some embodiments, the needle membrane fixing plate 2 is provided with at least two positioning holes 22, and the positioning holes 22 are used to position the upper needle membrane 4 or the lower needle membrane 5, so as to facilitate the installation operation of the upper needle membrane 4 or the lower needle membrane 5.
