When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0015] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0016] Please see Figures 1 to 7 The shielding cover pressing device according to one embodiment of the present utility model includes a body 10, a feeding component 20 installed on the top surface of the body 10, a support plate 30 installed above the feeding component 20, and a loading / unloading component 40 and a pressing component 50 installed on the bottom surface of the support plate 30.
[0017] The feeding assembly 20 includes an X-axis linear module 21 mounted on the top surface of the machine body 10, a fixture 22 connecting the slide of the X-axis linear module 21, and a guide plate 23 connected to one side of the machine body 10; the guide plate 23 is located on one side of the X-axis linear module 21.
[0018] The jig 22 has multiple evenly spaced receiving cavities 220 on its top surface, which are used to position and receive the PCB board 24. Please refer to... Figure 6 and Figure 7To understand this, multiple shielding cover brackets 25 are fixedly installed on each PCB board 24. The multiple shielding cover brackets 25 are distributed in a discontinuous manner, and the closed area formed by their encirclement is the shielding area. A tray 26 is placed on the guide plate 23, and shielding covers 27 are placed evenly spaced on the tray 26. The shielding covers 27 are used to match and connect the shielding cover brackets 25.
[0019] Specifically, in this embodiment, the shielding bracket 25 is a closed ring-shaped metal frame. The interior of the metal frame is used for the corresponding insertion of the pins 270 of the shielding cover 27 to achieve a fixed connection between the shielding bracket 25 and the shielding cover 27.
[0020] The support plate 30 is connected to the top surface of the body 10 at its four opposite corners via columns 31, thereby achieving the connection and installation of the support plate 30 and the body 10.
[0021] The loading and unloading assembly 40 includes a Y-axis linear module 41 mounted on the bottom surface of the support plate 30, a loading and unloading lifting cylinder 42 connected to the slide of the Y-axis linear module 41, a support plate 43 connected to the end of the loading and unloading lifting cylinder 42, and a plurality of suction nozzles 44 evenly spaced on the support plate 43; the suction nozzles 44 are used to pick up the shielding cover 27.
[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the Y-axis linear module 41 is positioned opposite to the guide plate 23. During actual operation, the Y-axis linear module 41 drives the suction nozzle 44 to move above the guide plate 23. The piston rod of the loading / unloading lifting cylinder 42 extends, driving the suction nozzle 44 vertically downwards until it picks up the shielding cover 27 on the tray 26. Then, the piston rod of the loading / unloading lifting cylinder 42 retracts, causing the shielding cover 27 to rise synchronously. The Y-axis linear module 41 drives the suction nozzle 44 to move horizontally above the X-axis linear module 21, meaning the shielding cover 27 is positioned above the X-axis linear module 21. Subsequently, the X-axis linear module 21 drives the fixture 22 to move below the support plate 43. At this point, the shielding cover 27 corresponds one-to-one with the shielding cover bracket 25. The piston rod of the loading / unloading lifting cylinder 42 extends again, initially embedding the pins 270 of the shielding cover 27 into the interior of the shielding cover bracket 25. After the initial docking is completed, the X-axis linear module 21 drives the fixture 22 to move directly below the pressing assembly 50, ready to perform the final pressing action.
[0023] The pressing assembly 50 includes a pressing lifting cylinder 51 installed on the bottom surface of the support plate 30, a lifting plate 52 connected to the end of the pressing lifting cylinder 51, a floating plate 53 elastically connected to the bottom of the lifting plate 52, and a plurality of pressing blocks 54 evenly spaced on the bottom surface of the floating plate 53. The pressing blocks 54 correspond one-to-one with the receiving cavity 220. The pressing blocks 54 are used to abut against the shielding cover 27 to push the pins 270 of the shielding cover 27 to be completely embedded into the interior of the shielding cover bracket 25. The interference fit between the pins 270 and the shielding cover bracket 25 is used to achieve a stable assembly of the shielding cover 27 and the shielding cover bracket 25.
[0024] Specifically, in this embodiment, guide rods 55 are connected to the four opposite corners of the floating plate 53, and each guide rod 55 is fitted with a spring 56. The guide rods 55 slide upwards through the lifting plate 52, and the springs 56 are sandwiched between the floating plate 53 and the lifting plate 52 to elastically support the floating plate 53. During the pressing process, the piston rod of the pressing lifting cylinder 51 extends, driving the lifting plate 52, the floating plate 53, and the pressing block 54 to press vertically downwards synchronously until the pressing block 54 abuts against the shielding cover 27. In this process, the elastic buffering effect of the springs 56 first allows the pressing block 54 to flexibly abut against the shielding cover 27, avoiding damage caused by instantaneous impact. Subsequently, the piston rod of the pressing lifting cylinder 51 continues to extend, increasing the downward pressure until the pin 270 is completely embedded inside the shielding cover bracket 25, completing the pressing assembly.
[0025] In this embodiment, the pressure block 54 is a urethane pressure block, whose soft properties can effectively prevent mechanical damage such as scratches and indentations to the surface of the shield 27 during the pressing process.
[0026] The aforementioned shielding cover pressing equipment has a simple structure and is easy to use. It achieves automated loading and unloading through the X-axis linear module 21, Y-axis linear module 41 and suction nozzle 44. With the help of the pressing block 54, it achieves flexible and uniform force application, ensuring that the shielding cover 27 and the shielding cover bracket have a stable interference fit, avoiding excessive force that could damage the PCB board 24 or the shielding cover 27. This automated operation significantly improves assembly efficiency and product qualification rate.
[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
