Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a packaging structure for a liquid crystal television display screen driver module. Background Technology

[0002] Display driver module packaging is the process of combining and protecting the display driver chip and related electronic components and circuits through specific processes and materials to form a complete and stable module.

[0003] Existing LCD display driver modules typically employ COG (Coding over Ink) packaging technology. This involves applying anisotropic conductive adhesive to the area on the glass substrate that will connect to the display driver module using a dispensing device. After pressing with other equipment, the two are integrated, completing the packaging of the display driver module. However, over time, the adhesive in the dispensing tube can easily clog the nozzle. When this happens, operators need to find a suitable new nozzle, remove the old one, and install a new one, followed by adjustments. This entire process is cumbersome and inconvenient. Therefore, we provide an LCD TV display driver module packaging structure to solve these problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 10This utility model is a packaging structure for a liquid crystal television display screen driving module, including a machine base 1; support columns 102 are symmetrically fixedly connected to both sides of the upper surface of the machine base 1, a bearing plate 103 is horizontally fixed to the top of the support columns 102, a slide table 3 is slidably connected to the outer wall of the bearing plate 103, a housing 4 is slidably connected to the outer wall of the slide table 3, a needle changing assembly is provided inside the housing 4, a lifting assembly is slidably provided on one side of the housing 4, the needle changing assembly includes an electric push rod 401, the electric push rod 401 is fixedly connected to the upper surface of the housing 4, the output end of the electric push rod 401 passes through the housing 4 and extends into the interior, a stop block 402 for use with the lifting assembly is fixed to the outer peripheral surface of the output end of the electric push rod 401, a rotating shaft 405 is rotatably provided at the end of the electric push rod 401, one end of the rotating shaft 405 passes through the housing 4, a storage plate 7 is fixedly connected to the end of the rotating shaft 405, and a positioning assembly 8 is provided on the upper surface of the storage plate 7.

[0031] Furthermore, the lifting assembly includes a gear 404, which is rotatably connected inside the housing 4. The teeth of the gear 404 are respectively engaged with a rack 403 and a rack 411. A fixing plate 5 is fixedly connected to the outer wall of the rack 411, and a rubber tube 6 is fixedly connected to the middle of the fixing plate 5.

[0032] Furthermore, a vertical groove 408 is provided on one side of the housing 4 to cooperate with the lifting assembly, and a connecting rod 412 is fixedly connected to the output end of the electric push rod 401, with the connecting rod 412 passing through the middle of the rotating shaft 405.

[0033] Furthermore, a guide rod 407 is fixedly connected inside the housing 4, and a guide groove 406 for use with the guide rod 407 is opened on the outer peripheral surface of the rotating shaft 405. A limit ring 409 is fixedly connected to the outer peripheral surface of the rotating shaft 405, and a spring 410 sleeved on the rotating shaft 405 is rotatably connected to the lower surface of the limit ring 409. The other end of the spring 410 is fixedly connected to the inner bottom surface of the housing 4.

[0034] The operation process of this embodiment is as follows: one side of the storage plate 7 is engaged with the existing needle 9 of the dispensing device, and the other side stores a new needle 9. When the needle 9 of the dispensing device becomes clogged, the electric push rod 401 is activated. The output end of the electric push rod 401 moves inside the housing 4. During the movement, the stop 402 at the output end of the electric push rod 401 contacts the rack 1 403, pushing the rack 1 403 to move in the slide groove 408 inside the housing 4. Due to the rack 1 403 and rack 2 411 meshes with gear 404. When stop 402 contacts rack 403, rack 403 descends, and gear 404 rotates, causing rack 411 to rise. As rack 411 rises, it drives the fixing plate 5 and hose 6 to rise. During the rise of hose 6, it disengages from needle 9 in storage plate 7. At this time, electric push rod 401 continues to move, and connecting rod 412 retracts into rotating shaft 405. When the output end of electric push rod 401 contacts rotating shaft 405, it causes the rotating shaft 405 to move. The limiting ring 409 outside the shaft 405 compresses the spring 410. During the movement of the shaft 405, the guide groove 406 on its outer wall forces the shaft 405 to rotate under the restriction of the guide rod 407. When the shaft 405 rotates 180 degrees, the guide rod 407 is located at the intersection of the arc groove and the vertical groove on the upper part of the guide groove 406. The storage plate 7 rotates 180 degrees accordingly under the drive of the shaft 405. At this time, the blocked needle 9 is replaced, and the new needle 9 is located below the tubing 6. When the electric push rod 401 retracts, the elastic potential energy of the spring 410 is released, the rotating shaft 405 rises, and the vertical end of the guide groove 406 outside the rotating shaft 405 moves along the guide rod 407. The rack 411 descends under the action of gravity. During the descent of the rack 411, it drives the gear 404 to rotate, which in turn drives the rack 403 to rise. During the downward movement of the rack 411, it drives the fixing plate 5 and the hose 6 to move together, so that the hose 6 can be engaged with the new needle 9 in the storage plate 7, thereby completing the replacement.

[0035] For a specific embodiment two, please refer to Figure 4 , Figure 8 , Figure 9 and Figure 10Based on the first specific embodiment, the positioning component 8 includes a lower ring body 802. Specifically, the lower ring body 802 is symmetrically fixed on the upper surface of the storage plate 7. An upper ring body 801 is rotatably connected to the top of the lower ring body 802. Multiple guide plates 804 are rotatably arranged inside the lower ring body 802. A gear 2 805 is fixedly connected to the upper surface of each guide plate 804. The tooth ends of the gear 2 805 are meshed with an internal gear ring 803. The internal gear ring 803 is fixedly connected to the inner wall of the upper ring body 801. The gear 2 805 is fixedly connected to the middle of the guide plate 804. A circular rod 810 is rotatably connected at one end to the inner bottom surface of the lower ring body 802. Multiple limiting rods 806 are slidably arranged inside the lower ring body 802 to cooperate with the guide plate 804. An inner ring 811 is fixedly connected inside the lower ring body 802. One end of the limiting rod 806 passes through the inner ring 811. A second limiting ring 808 is fixedly connected to the outer wall of the limiting rod 806. A second spring 807 is fixedly connected to one side of the second limiting ring 808 and sleeved on the limiting rod 806. The other end of the second spring 807 is fixedly connected to the outer wall of the inner ring 811.

[0036] Furthermore, the inner wall of the inner ring 811 is symmetrically provided with slots 809, and a needle 9 is engaged inside the slots 809. The outer wall of the needle 9 is provided with a limiting groove 901 for use with the limiting rod 806. The needle 9 and the tubing 6 are used in conjunction with each other.

[0037] The operation process of this embodiment is as follows: Rotate the upper ring body 801 counterclockwise. The internal gear ring 803 inside the upper ring body 801 rotates. The rotation of the internal gear ring 803 drives the gear 805 on the circumference of the circular rod 810 to rotate. Since the gear 805 is fixed to the guide plate 804, the gear 805 and the guide plate 804 rotate together. During the rotation, the guide plate 804 contacts the limiting rod 806. During the movement of the limiting rod 806, the limiting ring 808 on the outer circumference of the limiting rod 806 compresses the spring 807. The spring 807 generates elastic potential energy. At this time, the limiting rod 806 extends and engages with the limiting groove 901 on the outer wall of the needle 9 to position the needle 9 and prevent the needle 9 from shaking during operation. When the guide plate 804 rotates to the groove opening, the elastic potential energy of the spring 807 is released, pushing the limiting rod 806 to retract from the limiting groove 901 on the outer wall of the needle 9. At this time, the needle 9 can be taken out.
