[0002] With the development of smart phones, smart phone peripheral accessories are also emerging in an endless stream. For example, mobile phone shells are not only made of plastic materials, but also made of all-metal materials. In order to meet different customer needs, a mobile phone shell with a plastic shell and metal buttons has emerged. Since the shell and the buttons are made of different materials, they cannot be directly installed. The solution adopted is to provide a metal sheet on the inside of the shell, and then fix the metal sheet and the metal buttons by welding. In order to facilitate operation, a fixture specially used for producing such mobile phone shells has emerged, such as the Chinese public patent document CN113894417A, a mobile phone shell button welding fixture and a welding device, which fixes the buttons on the outside of the mobile phone shell by setting an outer fixture, fixes the metal sheet on the inside of the mobile phone shell by setting an inner fixture, and loads the buttons through a loading platform at the same time, which is very suitable for laser welding of mobile phone shell buttons, and improves welding efficiency.

[0003] It can be seen from the above-mentioned public documents that the structure of the jig is very complicated. During processing, two clamps are needed to fix the shell and the buttons respectively before operation can be performed.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Please refer to Figure 1-5 ;

[0022] The jig described in the utility model can adapt to different sizes of mobile phone shells of the same mobile phone to achieve adaptive fixation, and is suitable for the dispensing installation of metal buttons and mobile phone shells. The overall structure is simpler, specifically comprising a base 1, on which a base 2 is provided. The base 2 in this embodiment is placed vertically. It should be noted that before the mobile phone shell and the button are assembled, a through groove is provided at the position of the mobile phone shell corresponding to the button. When the mobile phone shell is fixed on the base 2, the position of the through groove faces downward, and at least one notch is provided on one side of the base 2. Corresponding to the position of the notch, a retractable clamping component 3 is provided in the base 2. The end of the clamping component 3 corresponds to the position of the mobile phone shell for installing the button. Corresponding to the two ends of the base 2, a fixed baffle 4 and a movable baffle 51 are respectively provided on the base 1, and an elastic member 3 52 is provided between the movable baffle 51 and the base 1;

[0023] In one embodiment, the fixture of the utility model is used together with an automated device. The structure of the automated device is not limited here, and the use process of the fixture is described.

[0024] First, external forces are applied to the movable baffle 51 and the clamping assembly 3 through an external device, so that the movable baffle 51 compresses the elastic member 3 52 and moves away from the base 2, and the clamping assembly 32 is retracted into the base 2. At this time, the mobile phone can be placed on the base 2;

[0025] When installing a small-sized mobile phone case, the shape of the base 2 in this embodiment is adapted to the mobile phone case. At this time, the movable baffle 51 is first released, and the movable baffle 51 moves toward the base 2 under the action of the elastic member 3 52, and finally cooperates with the end of the base 2 to clamp and fix the edge of the mobile phone case. At this time, the through groove of the mobile phone case is located below the pressing component 3;

[0026] When installing a large-sized mobile phone case, the shape of the base 2 in this embodiment is not important, but it cannot be larger than the space in the inner cavity of the mobile phone case. Preferably, the base 2 is adapted to the shape of the small-sized mobile phone case. At this time, the movable baffle 51 is released first, and the movable baffle 51 moves toward the base 2 under the action of the elastic member 3 52, while pushing the mobile phone case to move toward the fixed baffle 4. Finally, one end of the mobile phone case contacts the fixed baffle 4, and the other end contacts the movable baffle 51. The large-sized mobile phone case is fixed under the clamping of the movable baffle 51 and the fixed baffle 4. At this time, the through groove of the mobile phone case is located below the pressing component 3;

[0027] Then put the glue-treated key into the through groove, and then release the clamping component 3, which applies downward pressure to the key to make the key fit tightly against the inner edge of the mobile phone case. After a period of time, the key is fixed to the edge of the mobile phone case, and then apply external force to the movable baffle 51 and the clamping component 3 to release the fixation of the mobile phone case and the key, and then the mobile phone case can be taken out.

[0028] It should be noted that no matter how the size of the mobile phone case changes, the distance between the end of the mobile phone case and the button The distance is fixed, so it will not cause the situation that it cannot be installed due to changes in the size of the mobile phone case.

[0029] The fixture structure described in the utility model is simpler, the manufacturing cost is low, and it is suitable for the glue dispensing installation of the mobile phone shell and the buttons, so that the installation and fixing methods of the mobile phone shell and the buttons are more abundant, the production methods are more numerous, and the cost is lower.

[0030] In the embodiment of the utility model, a limiting movable groove 53 is provided on the base 1, and a guide shaft 54 ​​is provided in the limiting movable groove 53. The guide shaft 54 ​​passes through the movable plate. The limiting movable groove 53 can limit the movable range of the movable baffle 51, and the guide shaft 54 ​​can limit the moving direction of the movable baffle 51. Preferably, there are two guide shafts 54, and the elastic member 52 is sleeved on the guide shaft 54.

[0031] One embodiment of the clamping assembly 3 of the utility model specifically includes a movable pressure block 31 inserted in the base 2, an elastic member 32 is provided between the movable pressure block 31 and the base 2, a strip hole 33 is provided on the base 2, a lever 34 is inserted through the strip hole 33, and the lever 34 is connected to the movable pressure block 31. The base 2 is placed vertically, so the strip hole 33 in this embodiment extends longitudinally, the strip hole 33 is inserted through the lever 34, and the lever 34 is connected to the movable pressure block 31; the movable range of the movable pressure block 31 can be limited by the limitation of the strip hole 33 and the lever 34;

[0032] First, the lever 34 is lifted upward along the strip hole 33 by an external device, and at the same time, the movable pressing block 31 is pulled into the base 2 and the elastic member 32 is compressed. Then, the mobile phone case is installed in the base 2. At this time, the through groove of the mobile phone case for installing the button just corresponds to the bottom of the movable pressing block 31. Then, the button is first glued by an external device, and then transferred and placed in the through groove, so that the button passes through the inner side of the mobile phone case, and at the same time, the button is bonded to the inner side of the mobile phone case. Finally, the lever 34 is released, and the movable pressing block 31 is ejected from the base 2 under the action of the elastic member 32, and the end of the movable pressing block 31 presses the button tightly, so that the button is close to the mobile phone case. After a period of time, the lever 34 is lifted up to make the movable pressing block 31 re-retract into the base 2, and then the mobile phone case can be taken out.

[0033] It should be noted that after the mobile phone case is fixed to the base 2, one side of the base 2 will be covered by the mobile phone case, so an activity space corresponding to the lever 1 34 should be provided on the base 1 for an external device to operate the lever 1 34.

[0034] Of course, the above is only one of the usage methods. The glue dispensing operation can also be performed after the button and the mobile phone case are assembled. Specifically, an avoidance position 39 corresponding to the button is provided at the end of the movable pressing block 31. After the movable pressing block 31 presses the button tightly, the glue dispensing gun is extended from the avoidance position 39 to dispense glue, and glue is injected into it to bond the mobile phone case and the button.

[0035] In the embodiment of the utility model, since the mobile phone case is placed in an upright manner, the mobile phone case is prone to tilting and deflecting after being placed on the base 2. For this reason, a pre-fixed structure is provided to limit the position of the mobile phone case. Two movable pressing blocks 35 are inserted in the base 2. The movable pressing blocks 35 are located on both sides of the movable pressing block 1 31. An elastic member 36 is provided between the movable pressing block 35 and the base 2. A strip hole 37 is provided on the base 2. The strip hole 37 is penetrated by a lever 38. The lever 38 is connected to the movable pressing block 35. The movable pressing block 35 can extend out of the edge of the base 2.

[0036] Before the mobile phone case is fixed on the base 2, the lever 1 34 and the lever 2 38 are first lifted by an external device, and the movable pressure block 1 31 and the movable pressure block 2 35 are retracted into the base 2 at the same time, and then the mobile phone case is installed into the base 2. For example, the mobile phone case is placed into the base 2 by an external device. At this time, the external device is not released, and the lever 2 38 is released first, and the movable pressure block 2 35 is pushed out under the action of the elastic member 2 36. In this embodiment, the movable pressure block 2 35 extends out of the edge of the base 2. At this time, the end of the movable pressure block 2 35 applies pressure to the inner edge of the mobile phone case to fix it relatively to the base 2, and then the buttons are installed and the lever 1 34 is released.

[0037] In addition, there are two movable pressing blocks 35. When the two movable pressing blocks 35 press the edge of the mobile phone case at the same time, the two movable pressing blocks 35 form two fixed points on the edge of the mobile phone case. The position of the edge of the mobile phone case between the two fixed points will become flat, which is more conducive to installing the buttons.
