Description

Technical Field

[0001] The utility model relates to a soldering device for liquid crystal displays, belonging to the technical field of soldering for liquid crystal displays. Background Technique

[0002] The structure of an LCD is to place a liquid crystal cell between two parallel glass substrates. TFT (Thin Film Transistor) is set on the lower substrate glass, and a color filter is set on the upper substrate glass. By changing the signals and voltages on the TFT, the rotation direction of liquid crystal molecules is controlled, so as to control whether the polarized light of each pixel point is emitted or not to achieve the display purpose. When an LCD is produced, soldering is required. At present, a fully automatic soldering machine is generally used for soldering;

[0004] Since the above-mentioned fully automatic soldering device completes the soldering operation of the liquid crystal display through automatic control inside, but the staff needs to manually control the placement and alignment operation of the liquid crystal display component structure. Because the specifications and sizes of the liquid crystal displays to be batch soldered are different, the liquid crystal display needs to be reinstalled and aligned each time, which brings certain adverse effects to the actual use. Therefore, improvement is needed. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Example 1 Please refer to Figures 1 - 7 , the present utility model provides a technical solution:

A heat dissipation fan box 10 with a dust filter net is fixedly installed on the top of the inner wall of the full-automatic soldering machine 1.

[0029] Specifically, as Figures 1 - 7 shown, the bottom of the rotating table 3 is fixedly connected to a supporting sliding plate 11. An annular groove 12 is provided at the bottom of the inner wall of the full-automatic soldering machine 1. The inner wall of the annular groove 12 and the surface of the supporting sliding plate 11 are slidably connected. Under the action of the supporting sliding plate 11 and the annular groove 12, the stable anti-tilting rotation of the rotating table 3 is ensured.

[0030] Furthermore, a vertical main fan 22 is fixedly installed on the inner wall of the heat dissipation fan box 10. A side inclined secondary fan 23 is fixedly installed on the side of the inner wall of the heat dissipation fan box 10. The side inclined secondary fan 23 is located on the side of the vertical main fan 22. The number of the heat dissipation fan boxes 10 is three, and the three heat dissipation fan boxes 10 are respectively connected to the front side and the left and right sides of the full-automatic soldering machine 1. Through the vertical main fan 22 and the side inclined secondary fan 23 inside the heat dissipation fan box 10, blowing heat dissipation operation can be carried out, so that the liquid crystal display screen can be quickly cooled after soldering for easy taking.

[0031] Specifically, as Figures 1 - 7 shown, the limiting component includes a limiting plate 13 and a limiting groove 14. The limiting plate 13 is fixedly connected to the side of the threaded sleeve plate 8. The limiting groove 14 is provided on the side of the inner wall of the lower groove. The inner wall of the limiting groove 14 and the surface of the limiting plate 13 are slidably connected. Through the arrangement of the limiting plate 13 and the limiting groove 14, the movement track of the threaded sleeve plate 8 is limited, so that the rotation of the threaded rod 7 can drive the threaded sleeve plate 8 to move.

[0032] Furthermore, a guiding balance groove 15 is provided on the lower surface of the inner wall of the regulation frame 5. The inner wall of the guiding balance groove 15 and the bottom of the positioning sleeve plate 9 are slidably connected.

[0033] Example 2 Please refer to Figures 1 - 7, the difference between this embodiment and Embodiment 1 lies in that: an electric cylinder 16 is fixedly installed on the side surface of the inner wall of the positioning sleeve plate 9, the output end of the electric cylinder 16 is fixedly connected with a restraint clamping frame 17, and a basic support plate 18 is clamped near the middle of the inner wall of the positioning sleeve plate 9.

The operation of the electric push rod 19 can drive the auxiliary clamping plate 20 to move, and the addition of the anti-slip soft pads 21 can be used for the anti-wear clamping effect of the liquid crystal display screen.

[0034] Working principle of the utility model: During use, staff can perform soldering operations on the liquid crystal display screen according to the PLC inside the fully automatic soldering machine 1. However, depending on the size of the liquid crystal display screen, different positioning templates 9 can be installed. That is, the positioning template 9 is tightly clamped and installed above the threaded template 8 for restraint and locking. Through the setting of the guiding balance groove 15, the bottom of the positioning template 9 can be constrained and guided, reducing the situation of the positioning template 9 tilting during movement. The operation of the driving motor two 6 can drive the threaded rod 7 to rotate. Through the setting of the limiting plate 13 and the limiting groove 14, the movement trajectory of the threaded template 8 is limited, so that the rotation of the threaded rod 7 can drive the threaded template 8 to move. The movement of the threaded template 8 can drive the positioning template 9 thereon to move. After opening the side door 4, the right side of the fully automatic soldering machine 1 can be exposed, enabling the positioning template 9 driven by the threaded template 8 to move out of the fully automatic soldering machine 1, facilitating staff to place the components of the liquid crystal display screen outside. The operation of the electric cylinder 16 can drive the restraint clamping frame 17 to move. The L-shaped clamping plate on the restraint clamping frame 17 can achieve the clamping effect of the main body. According to the different sizes of the display screen, the operation of the electric push rod 19 can be controlled. The operation of the electric push rod 19 can drive the auxiliary clamping plate 20 to move. The anti-slip soft pad 21 is added to achieve the anti-wear clamping effect for the liquid crystal display screen. If the specification dimensions of the new and old batches of the liquid crystal display screen change greatly, the entire positioning template 9 can be replaced. The soldering operation of the liquid crystal display screen is carried out at the rear side of the inner wall of the fully automatic soldering machine 1, and the liquid crystal display screen is placed in the four control frames 5 at the top of the rotating table 3. After the soldering is completed at the rear side, the driving motor one 2 operates to drive the rotating table 3 to rotate and change direction. Under the action of the support slide plate 11 and the annular groove 12, the stable anti-tilting rotation of the rotating table 3 is ensured. During the rotation, the liquid crystal display screen can pass through three heat dissipation fan boxes 10 successively after soldering. Through the vertical main fan 22 and the side inclined secondary fan 23 inside the heat dissipation fan box 10, the blowing and heat dissipation operation can be carried out, so that the liquid crystal display screen can be quickly cooled after soldering for easy taking. The function of restraining and turning soldering for multiple liquid crystal display screens of different specifications and the subsequent operation effect of quick cooling for easy taking and placing can be realized.
