Description

Technical Field

[0001] This utility model relates to the field of assembly equipment, specifically a semi-automatic assembly equipment for screwing on metal clips of a liquid crystal display module. Background Technology

[0002] In the design and assembly of small electrical appliances, due to the compact internal space and strict cost control, the fixing method of the LCD display module must balance structural stability, assembly efficiency, and economy. Therefore, a simple, low-cost, and easy-to-install mechanical fixing solution is typically adopted: a metal frame is installed around the LCD display module, tightly covering the edge of the LCD screen, protecting the screen, enhancing structural rigidity, and assisting in positioning. Multiple slender legs extend from the bottom of the metal frame, precisely aligning with pre-drilled holes on the control circuit board and inserting them through. Subsequently, the ends of the legs are twisted or bent at a certain angle on the back of the control circuit board, forming a sturdy metal clip structure, thus mechanically locking the LCD display module to the control circuit board. This fixing method eliminates the need for additional screws or adhesives, saving material costs and assembly time, avoiding the risk of loosening due to thermal expansion and contraction or vibration, and facilitating disassembly and replacement during later maintenance. Furthermore, the metal frame itself also possesses a certain electromagnetic shielding function, helping to improve the overall anti-interference capability of the equipment. Therefore, this structure is widely used in small home appliances and consumer electronics products where space is limited and cost is sensitive.

[0003] Because the circuit boards and LCD modules of these small electrical appliances are inexpensive, and the size and specifications of the LCD modules are often non-standard parts, if specialized fully automated equipment is used to lock the iron frame legs that connect the LCD modules to the control circuit boards, various molds need to be specially customized. Although this can improve production efficiency, the cost of customized molds is high, so it is difficult to reduce production costs. When locking by manually twisting the legs, the production efficiency is low and it is easy to cause hand injuries.

[0004] Therefore, in order to reduce production costs while maintaining production efficiency, a semi-automatic assembly device for screwing iron buckles on liquid crystal display modules is proposed. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a semi-automatic assembly device for screwing iron buckles on liquid crystal display modules.

[0006] The objective of this utility model can be achieved through the following technical solutions: This utility model discloses a semi-automatic assembly device for tightening iron buckles of a liquid crystal display module, comprising an operating table and an assembly frame. The assembly frame is disposed on the operating table and is equipped with a torsion component and a fixing plate. The torsion component includes a swing arm and several screws, with the screws connected to the swing arm. The fixing plate has several through holes, and the screws slide through the through holes respectively. A positioning rod is provided on the inner sidewall of each through hole, and the positioning rod is slidably disposed in the spiral groove on the screw. The assembly area of ​​the operating table is used to fix the assembly parts. The swing arm drives the screws to rotate and torsion the iron frame support legs as the lifting action is performed.

[0007] As a further embodiment of this utility model, one end of the swing arm is rotatably mounted on the assembly frame, and a transmission mechanism is provided between the swing arm and the plurality of screws, through which the swing arm drives the plurality of screws to rise, fall and rotate.

[0008] As a further embodiment of this utility model, the transmission mechanism includes a mounting plate and a connecting rod, with both ends of the connecting rod rotatably connected to the swing arm and the mounting plate, respectively.

[0009] As a further embodiment of this utility model, a slider is rotatably provided on the top of the screw, and the screw is connected to the mounting plate through the slider.

[0010] As a further embodiment of this utility model, the mounting plate is provided with a plurality of sliding grooves, and the slider is slidably mounted in the sliding grooves.

[0011] As a further embodiment of this utility model, a torsion head is provided at the bottom of the screw, and the torsion head has a clamp-like structure.

[0012] The beneficial effects of this utility model are as follows: An assembly area is provided on the operating table for placing assemblies formed by the combination of an LCD screen and an iron frame. Multiple movable sliding plates are provided on the assembly area for limiting the position of the assemblies and adapting to assemblies of different sizes. A swing arm on the assembly frame can rotate based on its connection point, and several screws are connected to the swing arm. Therefore, as the swing arm rotates, the screws can move up and down. A fixing plate is provided below the swing arm on the assembly frame. The screws pass through through holes in the fixing plate and suspend above the assemblies. The through holes in the fixing plate restrict the position of the screws, preventing them from deviating during the lifting and lowering process. Meanwhile, a positioning rod is installed on the inner wall of the through hole. The positioning rod engages with the spiral groove of the screw. Since the position of the positioning rod inside the through hole is fixed, while the screw rises and falls with the movement of the rocker arm, the spiral groove engages with the positioning rod during the screw's rise and fall, driving the screw to rotate. Through the rotation of the screw, it descends to contact the support leg of the assembly, allowing the support leg to be rotated at an angle, thus locking the LCD screen and the iron frame. This semi-automated assembly process improves work efficiency compared to manual assembly while avoiding excessively high production costs. Attached Figure Description

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figures 1-3As shown, this utility model discloses a semi-automatic assembly device for screwing iron buckles on a liquid crystal display module. It includes an operating table 1 and an assembly frame 2. The assembly frame 2 is mounted on the operating table 1 and has a torsion assembly and a fixing plate 4. The torsion assembly includes a swing arm 3 and several screws 8. The screws 8 are connected to the swing arm 3. The fixing plate 4 has several through holes 10. The screws 8 slide through the through holes 10, and each through hole 10 has a positioning rod on its inner sidewall. The positioning rod slides within the spiral groove of the screw 8. The assembly area of ​​the operating table 1 is used to fix the assembly parts. The swing arm 3 drives the screws 8 to rotate and torsion the iron frame support legs 9 as the device moves up and down.

[0017] The control panel 1 has an assembly area for placing assemblies formed by combining LCD screens and iron frames. The assembly area has multiple movable sliding plates for limiting the position of the assemblies and adapting to assemblies of different sizes. A swing arm 3 on the assembly frame 2 can rotate based on its connection point, and several screws 8 are connected to the swing arm 3. Therefore, as the swing arm 3 rotates, the screws 8 can move up and down. A fixing plate 4 is located below the swing arm 3 on the assembly frame 2. The screws 8 pass through through holes 10 on the fixing plate 4 and suspend above the assemblies. The through holes 10 on the fixing plate 4 restrict the position of the screws 8, preventing them from deviating during the lifting and lowering process. Meanwhile, a positioning rod is provided on the inner wall of the through hole 10. The positioning rod is used to engage with the spiral groove of the screw 8. Since the position of the positioning rod in the through hole 10 is fixed, and the screw 8 will rise and fall with the movement of the swing rod 3, during the rising and falling of the screw 8, the spiral groove engages with the positioning rod and drives the screw 8 to rotate. Through the rotation of the screw 8, the screw 8 descends to contact the assembly support leg 9 and can then twist the angle of the support leg 9, so that the support leg 9 twists and locks the LCD screen and the iron frame into a locked state. Through the semi-automatic assembly of the assembly equipment, work efficiency is improved compared with manual assembly, while avoiding excessive production costs.

[0018] Since only one end of the swing arm 3 is hinged to the assembly frame 2, as the swing arm 3 swings, a certain angle will be formed between the swing arm 3 and the screws 8, which will cause the screws 8 to be unable to rise and fall vertically. In order to avoid this problem, in one embodiment, one end of the swing arm 3 is rotatably mounted on the assembly frame 2, and a transmission mechanism is provided between the swing arm 3 and the screws 8. The swing arm 3 drives the screws 8 to rise, fall and rotate through the transmission mechanism.

[0019] Specifically, the transmission mechanism includes a mounting plate 6 and a connecting rod 5, with both ends of the connecting rod 5 rotatably connected to the rocker arm 3 and the mounting plate 6, respectively. Several screws 8 are rotatably mounted on the mounting plate 6. Because the connecting rod 5 and the mounting plate 6 are arranged between the screws 8 and the rocker arm 3, and are rotatably connected in sequence, as the rocker arm 3 swings based on the hinge point, the connecting rod 5, the mounting plate 6, and the screws 8 will automatically adjust to a suitable angle, allowing the screws 8 to rise and fall vertically within the through hole 10.

[0020] As a further embodiment of this invention, a slider 7 is rotatably mounted on the top of the screw 8, and the screw 8 is connected to the mounting plate 6 via the slider 7. Since the number and position of the locking legs 9 vary depending on the different control circuit boards on which different LCD displays are mounted, to facilitate assembly according to different LCD displays and control circuit boards, the screw 8 is rotatably mounted on the slider 7, and the slider 7 is then slidably connected to the mounting plate 6. Simultaneously, several grooves are provided on the mounting plate 6, and the slider 7 is slidably installed within these grooves. After the slider 7 is slidably installed into the groove, a fixing device is provided within the groove to lock the slider 7 and prevent it from slipping.

[0021] As a further embodiment of this invention, a torsion head is provided at the bottom of the screw 8, and the torsion head has a clamp-like structure. Specifically, clamp-like structures extend from opposite sides of the bottom of the screw 8, and the clamp-like structures on both sides gradually narrow from high to low, forming an inverted triangle. As the screw 8 descends until it contacts the support leg 9, the clamp-like structures on both sides will abut against the two sides of the support leg 9. As the screw 8 rotates, the clamp-like structures will twist the support leg 9, thereby locking its rotation direction.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
