TECHNICAL FIELD
[0001] The utility model relates to automatic control technical field, in particular to a kind of automatic pressure maintaining equipment with temperature control, alarm and pressure balance. BACKGROUND
[0002] With the rapid development of science and technology, mobile phones have become an indispensable tool in people's lives. In the production and manufacturing process of mobile phones, various process treatments are needed to ensure the quality and performance of mobile phones, among which the pressure maintaining process is a crucial link. With the increasing power and complexity of mobile phones, the precision and reliability of production processes are increasingly demanding. Automatic pressure maintaining machines can ensure consistent pressure maintaining treatment for each mobile phone during production through precise pressure control and automated operation processes, improving product consistency and stability.
[0003] In the prior art, most mobile phone pressure maintaining machines only use up-down heating to cure glue. Up-down heating requires heat to be conducted through the screen to the frame of the mobile phone. The up-down heating scheme fails to effectively control local temperature, which may cause the entire mobile phone to be too hot and may even cause equipment failure. Moreover, up-down heating cannot fully activate the glue, resulting in poor glue curing effect and affecting the adhesive properties of the glue. The existing equipment does not have a dedicated heat dissipation design, and the heat generated during the glue curing process cannot be dissipated in time, further affecting the curing effect. If manual lever is used to apply pressure, the force of manual control is unstable and difficult to accurately adjust, which may cause uneven pressure and affect the curing effect of the glue. The existing methods cannot provide effective side heating and heat dissipation design, resulting in insufficient activation of the glue during the curing process and poor pressure bonding effect. Pressure control is not accurate and poses a potential threat to the safety of mobile phone equipment.

[0033] As Figure 4As shown, when the workpiece needs to be pressed down, the driving motor 601 starts to work at this time, driving the gear 602 to rotate, and the gear 602 and the rack 603 are engaged and moved, and when the rack 603 moves, the force arm 604 is pulled down, and the buckle 2 is in a clamping state at this time, so the force arm 604 drives the pressing plate 605 to be pressed down, and when the pressing plate 605 contacts the object, the side contacted first is adjusted by the balancer 606, and then the pressing plate 605 is ensured to be parallel to the object and the pressure is uniform when the object is finally pressed, at this time, the two pressure sensors 607 feedback the pressure for the operator to record and judge.
[0034] As shown in the figure, Figure 5 The inside of the case 1 is provided with an automatic centering clamp mechanism 7, which includes two servo motors 701 mounted in the inside of the case 1, two synchronous pulleys 702 are rotatably connected in the inside of the case 1, synchronous belts 703 are mounted between the two synchronous pulleys 702 and the corresponding servo motors 701, the inner ends of the two synchronous pulleys 702 are fixedly connected with lead screws 704, the other ends of the two lead screws 704 are mounted with heating sliding blocks 705, the outer walls of the two heating sliding blocks 705 are slidably connected with the inner walls of the corresponding heating fixed edges 4, the inner walls of the heating fixed edges 4 provide accurate guidance for the heating sliding blocks 705, so that the heating sliding blocks 705 can keep accurate position and direction during sliding, and ensure that the movement trajectory of the heating sliding blocks 705 meets the design requirements, thereby improving the accuracy of the whole heating and clamping operation, the bottoms of the two heating sliding blocks 705 are mounted with heating sheets 5, and the periphery and bottom are heated by the plurality of heating sheets 5, avoiding the limitation of up-down heating, which can ensure uniform curing of the glue, and at the same time reduce the direct impact of heat on the screen, prevent the screen from overheating or shorten the service life, and the inside of the case 1 is provided with a temperature alarm 706 near the heating sliding block 705.
