DETAILED DESCRIPTION

[0021] 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.

[0022] Please refer to Figure 1-5 ;

[0023] The jig described in the utility model is used for the dispensing installation of metal buttons and mobile phone shells, and the overall structure is simpler, specifically comprising a base 1, on which a base 2 for fixing the mobile phone shell 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 not assembled, the mobile phone shell is provided with a through groove at the position corresponding to the button. When the mobile phone shell is fixed on the base 2, the position of the through groove faces downward, and a notch 31 is provided on one side of the base 2 corresponding to the through groove. A movable pressing block 32 is penetrated in the base 2 at the position corresponding to the notch 31, and an elastic member 33 is provided between the movable pressing block 32 and the base 2. A strip hole 34 is provided on the base 2. The base 2 is placed vertically, so the strip hole 34 in this embodiment extends longitudinally, and a lever 35 is penetrated through the strip hole 34, and the lever 35 is connected to the movable pressing block 32; the range of motion of the movable pressing block 32 can be limited by the limitation of the strip hole 34 and the lever 35;

[0024] 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.

[0025] First, the lever 35 is lifted upward along the strip hole 34 by an external device, and at the same time, the movable pressure block 32 is pulled into the base 2 and the elastic member 33 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 pressure block 32. 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 the button is bonded to the inner side of the mobile phone case. It should be noted that a clearance position corresponding to the button is provided on the base 1. Finally, the lever 35 is released, and the movable pressure block 32 is ejected from the base 2 under the action of the elastic member 33, and the end of the movable pressure block 32 presses the button tightly, so that the button is close to the mobile phone case. After a period of time, the lever 35 is lifted up to retract the movable pressure block 32 into the base 2 again, and then the mobile phone case can be taken out.

[0026] 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.

[0027] 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, a notch 4 36 corresponding to the button is provided at the end of the movable pressing block 1 32. After the movable pressing block 1 32 presses the button, a glue dispensing gun is inserted into the notch 4 36 to dispense glue, and glue is injected into it to bond the mobile phone case and the button.

[0028] 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, specifically including two notches 41 on both sides of the notch 31, corresponding to the position of the two notches 41, a movable pressing block 42 is penetrated in the base 2, an elastic member 43 is provided between the movable pressing block 42 and the base 2, a bar hole 44 is provided on the base 2, a lever 45 is penetrated in the bar hole 44, and the lever 45 is connected to the movable pressing block 42. The movable range of the movable pressing block 42 can be limited by the limitation of the two bar holes 44 and the two levers 45;

[0029] Before the mobile phone case is fixed on the base 2, the lever 1 35 and the lever 2 45 are first lifted by an external device, and the movable pressure block 1 32 and the movable pressure block 2 42 are retracted into the base 2, 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 45 is released first, and the movable pressure block 2 42 is pushed out under the action of the elastic member 2 43. In this embodiment, the movable pressure block 2 42 extends out of the edge of the base 2. At this time, the end of the movable pressure block 2 42 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 35 is released.

[0030] The utility model is directed to one embodiment of the base 2, specifically a substrate 1 21 fixedly mounted on the base 1, one end of the substrate 1 21 is combined with a substrate 2 22, the substrate 1 21 and the substrate 2 22 both have the contour of the inner side of the mobile phone shell, in the initial state, the substrate 2 22 is close to the substrate 1 21 under the action of external force, and the model formed at this time is smaller than the size of the mobile phone shell, which is convenient for the mobile phone shell to be loaded, and after the mobile phone shell is loaded, the substrate 2 22 moves away from the basic direction, so that the substrate 1 21 and the substrate 2 22 are respectively in conflict with the edge positions of the two ends of the inner side of the mobile phone shell, thereby fixing the mobile phone shell;

[0031] In addition, there are two movable pressing blocks 42. When the two movable pressing blocks 42 press the edge of the mobile phone case at the same time, the two movable pressing blocks 42 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 buttons.

[0032] In this embodiment, the substrate 1 21 is fixedly arranged, and the substrate 2 22 is movably arranged. There is no limitation on the connection method of the substrate 2 2 . For example, it can be slidably connected to the substrate 1 21 , or movably connected to the base 1 .

[0033] This embodiment describes the connection method of the substrate two 22, specifically, the substrate two 22 is slidably connected to the substrate two 22, and an elastic member three 23 is provided between the two, and a toggle block 24 is provided at the end face of the substrate two 22; before assembling the mobile phone case, the toggle block 24 is first pushed toward the substrate one 21 through an external device, so that the substrate two 22 follows the movement and approaches the substrate one 21, and then the mobile phone case is put in, and then the toggle block 24 is released, and the substrate two 22 is pushed to move away from the substrate one 21 under the action of the elastic member three 23, and finally conflicts with the inner edge of the mobile phone case.

[0034] Furthermore, a fixing plate 25 is provided at one end of the substrate 1 21 close to the substrate 2 22, a limiting groove 26 is provided in the fixing plate 25, a slot cooperating with the fixing plate 25 is provided in the substrate 2 22, and a toggle block 24 is placed in the limiting groove 26. The mutual cooperation between the toggle block 24 and the limiting groove 26 can prevent the substrate 2 22 from being separated from the substrate 2 22. At the same time, the mutual cooperation between the fixing part and the slot can limit the sliding direction of the substrate 2 22 from deviation.

[0035] Based on the above method, the base 2 is suitable for installing buttons of mobile phone shells of the same style and different sizes. The distance between the end of the mobile phone shell and the button is fixed. At this time, no matter how the size of the mobile phone shell changes, the button can be installed.

[0036] One of the embodiments of the base 1 of the utility model specifically includes a bottom plate 11 and a vertical plate 12 which are arranged perpendicular to each other, a base plate 1 21 is fixed on the vertical plate 12, an end surface of a base plate 22 is in close contact with the vertical plate 12, and the vertical plate 12 is provided with a notch 3 13 corresponding to the toggle block 24, and the notch 3 13 is provided to provide space for the movement of the toggle block 24. In addition, the positions of the vertical plate 12 corresponding to the toggle rod 1 35 and the toggle rod 2 45 should be provided with avoidance positions to provide space for the external components to move the toggle rod 1 35 and the toggle rod 2 45.
