[0027] The utility model provides a high-precision mobile phone cover pressing device, including a frame 1 and a pressing upper mold 4, a driving device 9 and a mounting seat 8 are installed in the frame 1, a screw is arranged in the mounting seat 8, the top of the screw is rotatably connected with a driven wheel 12, the driven wheel 12 is rotatably connected with the driving device 9 through a transmission belt 14, the driving device 9 drives the driven wheel 12 to rotate together through the transmission belt 14, and the driven wheel 12 drives the screw to rotate and lift when rotating, the screw is arranged vertically downward and the bottom of the screw is connected with a lifting plate 22, a mounting frame 10 is fixedly connected below the lifting plate 22, the lower end surface of the mounting frame 10 is symmetrically provided with an "L"-shaped support frame 18 for installing the pressing upper mold 4, the bottom of the frame 1 is fixedly connected with a pressing lower mold 3 arranged corresponding to the pressing upper mold 4, specifically, the pressing lower mold 3 is arranged just below the pressing upper mold 4, and the pressing lower mold 3 is used to install the part to be mounted 5. At least one fixing screw 16 is threadedly connected on the mounting frame 10. The utility model has two fixing screws 16, which are symmetrically arranged at positions close to the support members. The fixing screws 16 abut against one side of the pressed upper mold 4. The mounting frame 10 is provided with at least one abutting column 17 on the side away from the fixing screw 16. There are three abutting columns 17, two of which are also symmetrically arranged at positions close to the support members, and the other is arranged in the middle of the two support members. The abutting column 17 abuts against the other side of the pressed upper mold 4. The fixing screws 16 and the abutting columns 17 cooperate to abut against both sides of the pressed upper mold 4 to limit the longitudinal movement of the pressed upper mold 4. At least one pressing screw 19 is arranged on the top of the mounting frame 10. The pressing screws 19 of the utility model are symmetrically arranged, and there are two of them in total. The bottom of the pressing screw 19 can abut against the upper end surface of the pressed upper mold 4.

[0028] Specifically, the pressing upper mold 4 is pushed in along the support frame 18, and the pressing upper mold 4 is supported and pressed tightly by two relative support frames 18 to limit the lateral movement of the pressing upper mold 4. When the pressing upper mold 4 is pushed to a certain position, it abuts against the abutment column 17, and then the fixing screw 16 is screwed in. The longitudinal movement of the pressing upper mold 4 is limited by the cooperation of the abutment column 17 and the fixing screw 16. Subsequently, the pressing screw 19 is screwed down, so that the pressing upper mold 4 is effectively fixed in the vertical direction to limit its up and down movement relative to the mounting frame 10, thereby improving the working stability and pressing accuracy of the pressing upper mold 4. Finally, the component 5 to be mounted is installed on the pressing lower mold 3, and the equipment can start working. The complex components are abandoned from the structural point of view, which greatly improves the convenience of installation and disassembly, and saves a lot of time and labor costs.

[0029] In this embodiment, the pressing upper mold 4 includes a fixed plate 41 and a cover plate mold 42. The fixed plate 41 and the cover plate mold 42 are movably connected through a plurality of vertical rods 45 and support rods. The utility model has a total of eight support rods, which are evenly arranged in four directions between the fixed plate 41 and the cover plate mold 42. A pressure sensor 44 is installed between every two vertical rods 45. The lower end surface of the pressure sensor 44 is provided with a plurality of spring 43 holes. The top of the cover plate mold 42 is provided with a spring 43 hole 2 corresponding to the spring 43 hole 1. The spring 43 hole 1 and the spring 43 hole 2 are used to install the spring 43. When the device During the pressing operation, the spring 43 will be compressed due to the pressing pressure. At this time, the pressure sensor 44 can monitor and transmit the pressure value of the spring 43 in real time, so that the operator can adjust the downward pressure applied around the cover mold 42 according to the pressure value of the spring 43 to ensure that the pressure in all directions is balanced and consistent, thereby effectively improving the pressing quality and accuracy of the component 5 to be mounted. At the same time, when the cover mold 42 descends, the spring 43 is compressed to generate elastic force to ensure a smooth pressing process, and to prevent operating errors from causing excessive instantaneous impact force to damage the pressing upper mold 4 and the pressing lower mold 3.

[0030] In this embodiment, in order to prevent the position of the screw rod from being offset when it is lifted or lowered, resulting in inaccurate product pressing, sliding blocks 11 are installed on both sides of the lifting plate 22, supporting side plates 6 are installed on both sides of the frame 1, and slide rails 7 are installed on the inner side of the supporting side plates 6. Through the sliding cooperation between the sliding blocks 11 and the slide rails 7, the lateral movement of the screw rod during the lifting process is limited to ensure that it is always lifted and lowered along the trajectory of the slide rails 7, thereby improving the overall lifting stability of the equipment and ensuring the accuracy of product pressing.

[0031] In addition, a sensor 21 is installed on the inner side of the supporting side plate 6, which senses the position of the sliding block 11 to prevent the mounting base 8 from rising too high and detaching from the slide rail 7. The sensor 21 is arranged at a position far away from the slide rail 7 to prevent the slider from directly colliding with the sensor 21 due to sensing failure, thereby causing damage to the equipment.

[0032] In this embodiment, the pressing lower mold 3 is symmetrically installed with a plurality of fixing parts 15, which can tightly press different parts of the to-be-mounted component 5, so as to achieve the purpose of effectively positioning and firmly fixing the to-be-mounted component 5. At the same time, the utility model can flexibly adjust and replace the fixing parts 15 according to the different sizes and shapes of the to-be-mounted component 5. It only needs to select or customize the fixing parts 15 of the corresponding size and structure to replace the original fixing parts 15, so as to easily cope with various types of to-be-mounted components 5, thereby greatly improving the adaptability of the equipment.

[0033] In this embodiment, the driven wheel 12 is installed in the upper cover 2, and the driving device 9 includes a driving wheel 13 installed in the upper cover 2. The driving wheel 13 is rotatably connected to the driven wheel 12 through a transmission belt 14. A dust cover 20 is installed above the driven wheel 12 and the driving wheel 13.

[0034] Specifically, the driving device 9 can be a cylinder or a motor (not limited here). When the driving device 9 is started, the driving device 9 will drive the driving wheel 13 to start rotating, and drive the driven wheel 12 to rotate together through the transmission belt 14. The rotation speed of the driving wheel 13 is controlled by adjusting the driving device 9, so as to achieve precise control of the lifting speed of the screw rod. In addition, the dust cover 20 protects the driven wheel 12 and the driving wheel 13 from the invasion of dust and other particulate matter, thereby extending their service life.
