Description

Technical Field

[0001] The present invention belongs to the technical field of mobile phone glass cover assembly, and relates to a press mounting component, specifically a positioning mechanism for rapid replacement of a press base. Background Art

[0002] With the popularization of electronic devices such as smart phones, the assembly process requirements for mobile phone glass covers are increasing day by day. During the bonding process of the glass cover and other functional auxiliary materials (such as sensors, touch modules, etc.), back glue is usually used for bonding. To ensure the bonding effect of the back glue, a press is usually used to perform a pressing treatment on the assembled product to activate the viscosity of the back glue and make it reach the best bonding strength.

[0003] In the existing press structure, the press base is a key component for fixing the position of the product to be pressed, and its stability directly affects the pressing effect. However, the current fixing method of the press base has the following problems:

[0004] 1. In the prior art, an additional bottom plate structure is usually used to lock the press base to ensure its stability during the pressing process. This method not only increases the material cost, but also requires disassembling and reinstalling the entire bottom plate structure when replacing press bases of different models, which is cumbersome to operate and seriously affects the production efficiency.

[0005] 2. Some prior arts use glue to directly bond the press base to the workbench surface of the press. However, the glue fixing method has the problem of insufficient bonding strength. After long-term use or high-frequency pressing operations, the press base is likely to become loose or even fall off, affecting the pressing accuracy. In addition, it is difficult to disassemble the press base without damage after being fixed with glue, resulting in the press base being unable to be reused, increasing the production cost.

[0006] 3. Due to the lack of a quick adjustment mechanism for the fixing method of the press base, when it is necessary to adjust the position of the press base to adapt to products of different sizes or models, it is often necessary to reinstall or replace the entire fixing structure, and rapid and accurate positioning adjustment cannot be achieved, reducing the versatility and production efficiency of the equipment.

[0007] Therefore, there is an urgent need for a new fixing solution for the press base to solve the problems of resource waste, cumbersome switching, unreliable fixing and insufficient adjustment flexibility existing in the prior art, so as to improve the applicability, stability and production efficiency of the press. Summary of the Invention

[0008] To solve the technical problems in the background art, the present invention proposes a positioning mechanism for rapid replacement of a press base, which realizes the rapid switching of the press base, reduces the downtime and improves the production efficiency.

[0009] The object of the present invention can be achieved by the following technical solutions:

[0010] A positioning mechanism for rapid replacement of a pressure-holding base, comprising: one or more positioning pressure blocks and a plurality of mounting holes correspondingly distributed on the metal panel of a pressure-holding machine. The positioning pressure block includes an integrally formed pressing portion and a connecting portion. A through hole is provided in the middle of the connecting portion. The connecting portion is fixedly connected to the corresponding mounting hole on the metal panel of the pressure-holding machine through a bolt passing through the through hole. The pressing portion is arranged on one side of the connecting portion. A clamping groove adapted to the pressure-holding base is provided between the pressing portion and the connecting portion. The positioning pressure block is clamped on the periphery of the pressure-holding base through the clamping groove, so as to position and install the pressure-holding base on the metal panel of the pressure-holding machine.

[0011] Further, the bottom surface of the pressing portion is adapted to the top surface of the pressure-holding base, so that when the positioning pressure block is clamped on the pressure-holding base, the bottom surface of the pressing portion is in close contact with the top surface of the pressure-holding base, restricting the displacement of the pressure-holding base in the vertical direction.

[0012] Further, the bottom surface of the pressing portion is provided with anti-slip lines to increase the frictional resistance between the positioning pressure block and the pressure-holding base.

[0013] Further, the bottom surface of the pressing portion is provided with an elastic cushion layer, and the elastic cushion layer is made of rubber or silica gel material to reduce the rigid contact between the positioning pressure block and the pressure-holding base.

[0014] Further, the side surface of the connecting portion is adapted to the side surface of the pressure-holding base, so that when the positioning pressure block is clamped on the pressure-holding base, the side surface of the connecting portion is in close contact with the side surface of the pressure-holding base, restricting the displacement of the pressure-holding base in the horizontal direction.

[0015] Further, the through hole is a strip-shaped through groove, and the bolt can horizontally move in the through hole along the extending direction of the strip-shaped through groove to adjust the installation position of the positioning pressure block.

[0016] Further, the extending direction of the strip-shaped through groove of the through hole is consistent with the length / width direction of the pressure-holding base, so that the positioning pressure block can adjust its position along the length / width direction of the pressure-holding base to adapt to pressure-holding bases of different sizes.

[0017] Further, a scale ruler is provided on one side of the strip-shaped through groove of the through hole to quantify the horizontal displacement adjustment amount of the positioning pressure block and achieve precise alignment of the pressure-holding base.

[0018] Further, a countersunk head groove adapted to the bolt head is provided on the periphery of the through hole, and the countersunk head groove is arranged on the top surface of the connecting portion to receive the bolt head and make the bolt head flush with the top surface of the connecting portion.

[0019] Further, an annular flange is provided at the bottom of the countersunk head groove, so that a pre-tightening force is generated when the lower end surface of the bolt head contacts the annular flange, preventing the bolt from loosening.

[0020] Advantages of the present invention: The positioning mechanism for rapid replacement of the pressure-holding base provided by the present invention enables the installation and replacement process of the pressure-holding base to be more convenient by providing one or more positioning blocks that can be quickly connected to and adjusted in position on the metal panel of the pressure-holding machine, and pressing and fixing the pressure-holding base through the positioning blocks. This realizes the rapid switching of the pressure-holding base, reduces downtime, improves production efficiency, and enables the repeated use of the pressure-holding base, saving production costs. In addition, by adopting an integrally formed design for the positioning blocks, the manufacturing and maintenance costs are low, it is applicable to pressure-holding bases of various specifications, and has strong versatility.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0025] As Figures 1 - 3 shown, the present invention provides a positioning mechanism for rapid replacement of a pressure-holding base, including: one or more positioning blocks 10 and a plurality of mounting holes correspondingly distributed on the metal panel 20 of the pressure-holding machine. The positioning block 10 includes a pressing portion 1 and a connecting portion 2 formed integrally. A through hole 21 is provided in the middle of the connecting portion 2. The connecting portion 2 is connected and fixed to the corresponding mounting hole on the metal panel 20 of the pressure-holding machine through a bolt 30 passing through the through hole 21. The pressing portion 1 is provided on one side of the connecting portion 2. A slot 3 adapted to the pressure-holding base 40 is provided between the pressing portion 1 and the connecting portion 2. The positioning block 10 is clamped on the periphery of the pressure-holding base 40 through the slot 3 to position and install the pressure-holding base 40 on the metal panel 20 of the pressure-holding machine.

[0026] The bottom surface 11 of the pressing part 1 is adapted to the top surface of the pressure-holding base 40, so that when the positioning pressing block 10 is engaged with the pressure-holding base 40, the bottom surface 11 of the pressing part 1 is in close contact with the top surface of the pressure-holding base 40, restricting the displacement of the pressure-holding base 40 in the vertical direction. The bottom surface 11 of the pressing part 1 is provided with anti-slip lines to increase the frictional resistance between the positioning pressing block 10 and the pressure-holding base 40. The bottom surface 11 of the pressing part 1 is provided with an elastic cushion layer, and the elastic cushion layer is made of rubber or silica gel to reduce the rigidity between the positioning pressing block 10 and the pressure-holding base 40. In summary, the anti-slip lines and the elastic cushion layer of the pressing part 1 can both increase the friction and reduce the rigid impact, effectively extending the service life of the equipment.

[0027] The side surface 22 of the connecting part 2 is adapted to the side surface of the pressure-holding base 40, so that when the positioning pressing block 10 is engaged with the pressure-holding base 40, the side surface 22 of the connecting part 2 is in close contact with the side surface of the pressure-holding base 40, restricting the displacement of the pressure-holding base 40 in the horizontal direction. Thus, the double limit of the pressure-holding base 40 is realized through the side surface 22 of the connecting part 2 and the bottom surface 11 of the pressing part 1, effectively preventing the displacement of the pressure-holding base 40 in the horizontal and vertical directions and ensuring the stability of the pressure-holding process of the pressure-holding machine.

[0028] The through hole 21 is a strip-shaped through groove, and the bolt 30 can move horizontally along the extending direction of the strip-shaped through groove in the through hole 21 to adjust the installation position of the positioning pressing block 10. Specifically, the extending direction of the strip-shaped through groove of the through hole 21 is consistent with the length / width direction of the pressure-holding base 40, so that the positioning pressing block 10 can adjust its position along the length / width direction of the pressure-holding base 40 to adapt to different sizes of the pressure-holding base 40. A scale ruler is provided on one side of the strip-shaped through groove of the through hole 21. Through the cooperation of the scale ruler and the strip-shaped through groove, the horizontal displacement adjustment amount of the positioning pressing block 10 can be quantified to achieve fine adjustment and meet the precise alignment requirements for different sizes of the pressure-holding base 40.

[0029] A counterbore 23 adapted to the head of the bolt 30 is provided on the periphery of the through hole 21, and the counterbore 23 is arranged on the top surface of the connecting part 2 to receive the head of the bolt 30 and make the head of the bolt 30 flush with the top surface of the connecting part 2. Specifically, an annular flange is provided at the bottom of the counterbore 23, so that a pre-tightening force is generated when the lower end surface of the head of the bolt 30 contacts the annular flange, preventing the bolt 30 from loosening and ensuring the stability during long-term use.

[0030] When the present invention works, first, place the pressure-holding base 40 between multiple mounting holes on the metal panel 20 of the pressure-holding machine. Use the bolt 30 to pass through the through-hole 21 of the positioning block 10, and preliminarily fix one or more positioning blocks 10 in the corresponding mounting holes of the metal panel 20 of the pressure-holding machine. Then, adjust the horizontal position of the positioning block 10 so that the card slot 3 of the positioning block 10 can be adaptively engaged with the peripheral side of the pressure-holding base 40. Press down the positioning block 10 so that the bottom surface 11 of the pressing part 1 is closely attached to the top surface of the pressure-holding base 40, and the side surface 22 of the connecting part 2 is closely attached to the side surface of the pressure-holding base 40, restricting the displacement of the pressure-holding base 40 in the vertical and horizontal directions. Finally, after confirming that the position of the pressure-holding base 40 is correct, tighten the bolt 30 to press and fix the pressure-holding base 40 to ensure that the pressure-holding base 40 will not shift or vibrate during the pressure-holding process of the pressure-holding machine. When it is necessary to replace the pressure-holding base 40, just loosen the bolt 30, slide the positioning block 10 along the strip-shaped through groove so that the positioning block 10 disengages from the current pressure-holding base 40, then take out the old pressure-holding base 40, put in the new pressure-holding base 40, readjust the position of the positioning block 10 and lock the bolt 30 to complete the replacement of the pressure-holding base 40. In summary, the present invention realizes the rapid replacement, precise positioning and stable fixation of the pressure-holding base 40, significantly improving the production efficiency and equipment reliability.

[0031] The above content is only an example and explanation of the structure of the present invention. Those skilled in the art of the present technology can make various modifications or supplements or use similar methods to replace the described specific embodiments, as long as they do not deviate from the structure of the invention or exceed the scope defined by this claim book, they should all belong to the protection scope of the present invention.
