In one embodiment, referring to fig. 17 and 18, the groove 42 is disposed inside a receiving area of the first pressing member 1, the receiving area is an area surrounded by the pressing portion 12, and the cross section of the groove 42 is circular. Specifically, a bump 43 is arranged in the accommodating area, the height of the bump 43 is greater than or equal to that of the pressing part 12, the groove 42 is arranged on the bump 43, and the height of the groove 42 is less than or equal to that of the bump 43. It can be understood that when the height of the groove 42 is equal to the height of the bump 43, the opening is flush with the surface of the bump 43, and the bottom is attached to the first press-fitting member 1; when the height of the groove 42 is smaller than the height of the bump 43, the opening is flush with the surface of the bump 43, and the bottom is located on the bump 43. Of course, in other embodiments, the grooves 42 may also be disposed outside the accommodating area on the first pressing member 1, the number, size and shape of the grooves are not affected by the structure of the pressed object, and the positioning accuracy can be improved by disposing a plurality of grooves 42 outside the accommodating area.
Further, the pressing fixture further comprises a buffer part, wherein the buffer part is elastically compressed between the marking function module and the first pressing part, and the buffer part can be made of metal, alloy, rubber, plastic and the like.
The buffering piece is arranged between the marking function module and the first pressing piece, so that the installation of the marking function module is facilitated, and when the first pressing piece is collided or falls, the external force transmitted from the first pressing piece to the marking function module is absorbed, and the marking function module is prevented from falling off from the first pressing piece due to the fact that the external force is large.
In one embodiment, the buffer member is an elastic ring, which is a mechanical part that works by elasticity, and is made of an elastic material, and is deformed by an external force and returns to its original shape after the external force is removed. The elastic ring can be a rubber ring, one end of the elastic ring is fixed in the accommodating cavity of the first pressing piece, and the other end of the elastic ring is attached to the side face of the marking function module. The elastic ring can reduce the impact of external force on the marking functional module under the action of external load, so that the marking functional module is not easy to fall off. Of course, in other embodiments, the buffer member may also be an elastic sheet, a spring tube, a bellows, a diaphragm, or the like.
As shown in fig. 19, a schematic flow chart of a manufacturing method of a housing provided in the embodiment of the present application is shown, where the manufacturing method of the housing includes:
110: and providing a shell, wherein the shell is provided with a colloid and a colloid protective film.
Specifically, the shell is provided with an inner surface and an outer surface, the inner surface of the shell is provided with a colloid, the colloid can be formed on the shell through a glue dispensing or back glue process, a colloid protective film is pasted on one side of the colloid, which is far away from the inner surface of the shell, and the colloid protective film is used for preventing external dust from scattering on the colloid. The housing may be a battery cover, i.e. a rear housing, of the terminal product, the battery cover being provided with glue for gluing to the middle frame.
120: and placing the shell in a pressing fixture, wherein the colloid protective film faces towards the marking functional module of the first pressing piece.
Specifically, place the casing in the spacing inslot of second pressfitting spare, the one side that is equipped with the colloid on the casing deviates from second pressfitting spare, and first pressfitting spare pressfitting is put on the casing, and the casing is placed between first pressfitting spare and second pressfitting spare promptly, and the pressfitting portion and the mark function module of first pressfitting spare contact with the colloid protection film simultaneously.
130: pressing the shell and the colloid through the pressing fixture; wherein the marking function module marks the housing.
Specifically, the surface of the first pressing piece, on which the pressing part is arranged, is aligned with the inner surface of the shell, and the pressing of the shell and the colloid is completed by applying pressure on the first pressing piece. When the shell is pressed by the first pressing piece in the shell manufacturing method, the marking function module is arranged on the first pressing piece, so that the shell can be marked at the same time, in other words, the shell is pressed and marked by the same process, the time of circulation of the shell in a plurality of processes can be reduced, and the shell manufacturing method is high in efficiency and low in cost. The pressing fixture has the pressing and marking functions, so that when the pressed object is pressed through the pressing fixture, a mark can be left on the pressed object, and the time spent on manual marking is reduced; in addition, the mark has a prompting function, and rework caused by pressure leakage when an object to be pressed which is not pressed enters the next working procedure can be avoided.
The features mentioned above in the description, the claims and the drawings can be combined with one another in any desired manner, insofar as they are of significance within the scope of the application.
The foregoing is a preferred embodiment of the present application, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
