The liquid crystal screen in this kind of product usually needs to be stably and firmly installed on PCBA to ensure the stability and reliability of display effect. In order to achieve this goal, the commonly used method is to use a liquid crystal screen fixed iron frame, which is designed with a series of iron sheet fasteners. These fasteners need to be bent to a specific angle (usually 90°) during assembly process, so that they can be closely attached to PCBA, thereby firmly fixing the liquid crystal screen in place. This fastening method not only provides necessary mechanical support, but also helps to maintain the stability of electrical connection between liquid crystal screen and PCBA.

[0026] The technical solutions of the present application will be further described in combination with the accompanying drawings and through specific embodiments.

[0027] Embodiment one

[0028] The iron buckle pressing device provided in the embodiment, like Figures 1-5As shown in the figure, wherein the components such as wires and air tubes in the device are omitted, including the tool base 1, the driving unit 2 and the pressing member 3, the tool base 1 is provided with a fixing part 11 for fixing the PCBA 6 and the fixed iron frame 7, the pressing member 3 is located on one side of the fixing part 11, the acting end of the driving unit 2 is connected with the pressing member 3, and the driving unit 2 drives the pressing member 3 to move towards the fixing part 11. Specifically, the device integrates the tool base, the driving unit and the pressing member as three core components, forming an efficient system for pressing the iron buckle. The tool base serves as the support basis of the whole device, the PCBA and the fixed iron frame are fixed in the fixing part, which ensures the stability and alignment accuracy during the pressing process, effectively avoiding displacement or inclination caused by improper manual operation, thereby reducing the damage risk of the buckle of the fixed iron frame during pressing. The driving unit serves as the power source of the whole pressing action, and its acting end is connected with the pressing member. By precisely controlling the movement of the driving unit, the pressing member can move stably, quickly and controllably towards the fixing part. The movement direction of the pressing member is perpendicular to the original extension direction of the buckle, so as to make the buckle of the fixed iron frame form a 90° bend, so that the buckle and the PCBA are tightly attached. This mechanical pressing method not only significantly improves the pressing efficiency, but also ensures the consistency and repeatability of the pressing force, thereby ensuring the product quality while greatly improving the production efficiency.

[0029] Preferably, the driving unit 2 and the pressing member 3 are each provided with two groups, which are respectively located on the left and right sides of the fixing part 11. By arranging one group of driving unit and pressing member on each of the left and right sides, simultaneous and symmetrical pressing of the iron frame buckle can be achieved, which not only ensures uniform distribution of pressing force and effectively avoids the problems of deflection or stress concentration caused by unilateral pressing, but also greatly shortens the pressing period and improves the production efficiency.

[0030] Preferably, the fixing part 11 is a fixing groove provided in the middle of the tool base 1 for accommodating the PCBA and the fixed iron frame, and the depth of the fixing groove is matched with the height of the PCBA. By designing the fixing part as a fixing groove with a height matched with that of the PCBA, the PCBA can be ensured to be in the best position during the pressing process, avoiding poor pressing or damage caused by positional deviation. At the same time, the design of the fixing groove also provides stable support for the PCBA and the iron frame, reducing the shaking caused by external interference and further improving the pressing accuracy and product quality. Further, the PCBA can be better fixed in the fixing groove through threaded connection.

[0031] Preferably, one side of the fixing groove is provided with a taking-out part 12 for conveniently taking out the PCBA and the fixed iron frame, and the taking-out part 12 is in communication with the fixing groove. The provision of the taking-out part makes it easy for the operator to take out the PCBA from the fixing groove through the taking-out part after the pressing is completed, thereby reducing the operation difficulty and labor intensity of production.

[0032] Preferably, the driving unit 2 comprises an electromagnetic valve 21 and two cylinders 22, the outer interface P of the electromagnetic valve 21 is connected with a gas source, the first gas pipe interface A of the electromagnetic valve 21 is respectively connected with the front end interface of the two cylinders 22, and the second gas pipe interface B of the electromagnetic valve 21 is respectively connected with the rear end interface of the two cylinders 22. In the embodiment, the operation of the tool is realized by controlling the opening and closing of the gas circuit through the electric signal. When the button is pressed, the electric signal is input to the electromagnetic valve, and after the button is released, the electromagnetic valve loses the electric signal. When no electric signal is input, the P→A path is always open, and at this time the front end of the cylinder push rod is compressed and retracted. When the button is pressed and the electric signal is input, the electric signal controls the P→B path to be ventilated, and the P→A path is disconnected, at this time the rear end of the cylinder push rod is pressed and moves forward, driving the compression member to start the compression work. After the button is released, the electric signal is lost, and the cylinder returns to the initial retracted state. In this way, the reciprocating motion of the double cylinders is controlled by the point-by-point button. The above structure not only improves the automation degree of the compression process, but also ensures the stability and consistency of the compression force, further improves the product quality and production efficiency. In addition, the combination of the electromagnetic valve and the cylinder also has the advantages of simple structure, convenient maintenance and the like.

[0033] Preferably, the compression member 3 comprises a connecting sheet metal part 31 and a compression plate 32, one end of the connecting sheet metal part 31 is fixedly connected with the acting end of the cylinder 22, and the other end of the connecting sheet metal part 31 is fixedly connected with the compression plate 32. The connecting sheet metal part, as the core component of the compression member, not only has sufficient strength and rigidity, but also can accurately transmit the driving force generated by the cylinder to the compression plate. At the same time, the design of the connecting sheet metal part also takes into account the stress condition in the compression process, ensuring the uniform distribution and stability of the compression force. In addition, the fixed connection mode of the connecting sheet metal part and the compression plate also enhances the reliability and durability of the compression member, so that the device can operate stably for a long time. Further, the connecting sheet metal part 31 is in U shape, and the compression plate 32 is fixedly connected horizontally to the bottom of the connecting sheet metal part 31. The U-shaped connecting sheet metal part design not only enhances its structural strength, but also can better withstand the lateral force in the compression process, avoiding deformation or damage caused by uneven stress. At the same time, the compression plate is fixedly connected horizontally to the bottom of the connecting sheet metal part, ensuring the vertical transmission of the compression force and avoiding poor compression caused by angle deviation. This design not only improves the compression precision, but also prolongs the service life of the compression member.

[0034] Preferably, the device further comprises a guide unit 4, which is installed in the tool base 1 and connected to the acting end of the air cylinder 22. Specifically, the guide unit 4 comprises a linear guide rail 41 and a sliding block 42, which are used to bear the linear reciprocating motion of the air cylinder. The tool base is provided with a receiving groove for accommodating the linear guide rail and the sliding block, and a pressing piece is located on the upper side of the receiving groove and is threadedly connected to the sliding block. The arrangement of the guide unit enables the air cylinder to move along a predetermined trajectory when driving the pressing piece, thereby avoiding poor pressing or damage caused by deviation of the movement trajectory. At the same time, the guide unit can also buffer and limit the movement of the air cylinder, ensuring the stability and reliability of the pressing process. This design not only improves the pressing precision, but also enhances the safety and stability of the device.

[0035] Preferably, the device further comprises a power supply 5, which is located at the bottom of the tool base 1 and electrically connected to the driving unit 2. The power supply is located at the bottom of the tool base, which is convenient for the operator to connect and maintain, and can avoid the interference of power lines on the pressing process. In this embodiment, a DC 24V1A power supply is selected.

[0036] Preferably, the contact edge of the pressing piece 3 that contacts the iron frame fastener is rounded. Specifically, since the pressing piece and the fastener contact the pressing plate in this embodiment, only the contact edge of the pressing plate needs to be rounded. Through the above-mentioned rounding, the friction and extrusion during the pressing process can be reduced, and the deformation or damage of the fastener caused by stress concentration can be avoided. At the same time, the rounding can also improve the durability and service life of the pressing piece, reducing the cost of replacement and maintenance.

[0037] The utility model is described through preferred embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. The utility model is not limited by the specific embodiments disclosed herein, and other embodiments falling within the scope of the claims of the present application all belong to the scope of protection of the utility model.
