The attaching platform 5 can move up and down in the three-dimensional space between the first profiling body 3 and the second profiling body 4, and is used for attaching the membrane 7 to be attached placed on the attaching sleeve 6.

Through evacuating equipment evacuation for the absorption hole will wait to laminate diaphragm 7 adsorb on the surface of laminating platform 5, ensures that the diaphragm 7 that waits to laminate can not be at the attached in-process because of external force skew, influences attached effect.
In addition, in order to prevent the bonding platform 5 from moving downward and further moving downward after contacting the first support surface 312 and the second support surface 412, damage to the first and second imitation bodies 3 and 4 or the bonding platform 5 may occur, in this embodiment, pressure sensors (not shown) may be disposed at the first support surface 312 and the second support surface 412, when the bonding platform 5 contacts the first support surface 312 and the second support surface 412 and further moves downward, a pressure may be generated, the pressure sensors detect a pressure signal, and a controller (not shown) connected to the pressure sensors may control the bonding platform 5 to stop moving.

Example two
The embodiment provides a bonding method, which is applied to the above bonding jig, as shown in fig. 7, and includes:
step 120, placing the membrane 7 to be bonded on the bonding platform 5;
step 140, nesting the attaching sleeve 6 of the semi-enclosed structure to be attached to the first imitation 3 and the second imitation 4;
step 160, in a vacuum state, the bonding platform 5 is lifted up, so that the membrane 7 to be bonded is bonded to the inner surface of the bonding sleeve 6 of the semi-surrounding structure to be bonded.
Optionally, before step 160, the attaching method further includes:
the attaching jig is placed in the vacuum cavity, and the vacuum cavity is vacuumized, so that the inside of the vacuum cavity reaches a preset vacuum value.
The vacuum cavity can be connected with a vacuum pumping device, and after the attaching jig is placed in the vacuum cavity, the vacuum pumping device can pump vacuum, so that the inside of the vacuum cavity reaches a preset vacuum value. The preset vacuum value may be-95 Kpa and below. The vacuum state can ensure that the membrane 7 to be attached is tightly attached to the attaching sleeve 6 with a semi-enclosed structure, and the membrane 7 and the attaching sleeve are prevented from falling off from each other.
Optionally, before step 120, the attaching method further includes: the attaching platform 5 is lifted up, so that the horizontal height of the attaching platform 5 is greater than the horizontal heights of the first imitation body 3 and the second imitation body 4.
The laminating platform 5 rises, and its horizontal height is greater than the horizontal height that first imitative body 3 and second imitative body 4 are located, is for more convenient placing the diaphragm 7 of waiting to laminate on the laminating platform, promotes laminating efficiency. It will be appreciated that placing the membrane 7 to be laminated on the lamination stage in other ways necessarily increases the difficulty of placing the membrane 7 to be laminated on the lamination stage.
Optionally, after the membrane 7 to be laminated is placed on the lamination platform 5, and before the lamination sleeve 6 of the semi-enclosed structure to be laminated is nested on the first imitation 3 and the second imitation 4, the lamination method further includes:
the attaching platform 5 descends, so that the horizontal height of the attaching platform 5 is smaller than the horizontal heights of the first imitation body 3 and the second imitation body 4.
Wherein, laminating platform 5 descends, makes the level that laminating platform 5 is located be less than the level that first imitative body 3 and second imitative body 4 are located, specifically is:
the attaching platform 5 is lowered, so that the distance between the horizontal height of the attaching platform 5 and the horizontal height of the first copying body 3 and the second copying body 4 is 1 mm to 2 mm.
It can be understood that, since the horizontal height of the lamination platform 5 is lower than the horizontal height of the first and second imitation bodies 3 and 4 by a distance between 1 mm and 2 mm, after the lamination sleeve 6 of the semi-enclosed structure to be laminated is nested on the first and second imitation bodies 3 and 4, the distance between the membrane 7 to be laminated and the lamination sleeve 6 of the semi-enclosed structure is between 1 mm and 2 mm, so that the subsequent vacuum lamination process can be conveniently realized.
In this embodiment, the membrane 7 to be bonded is placed on the bonding platform 5, and the membrane 7 and the bonding platform 5 are aligned in equal size and then placed on the bonding platform 5 based on the size of the membrane 7 and the size of the bonding platform 5.
In many mobile terminals, the size of the mobile terminal screen is typically rectangular. The size of the membrane 7 is designed to be rectangular corresponding to the size of the mobile terminal screen. The size of the mobile terminal screen may also be a special-shaped screen, etc., and the embodiment is not limited to the specific shape of the mobile terminal screen. Here, it should be noted that the size of the screen of the mobile terminal, the size of the attaching platform, and the size of the membrane 7 to be attached should be the same. When the membrane 7 to be bonded is placed on the bonding platform 5, the membrane 7 needs to be aligned with the bonding platform 5 in equal size and then placed on the bonding platform 5. It can avoid subsequent laminating error, improves laminating precision.
Optionally, after the film 7 to be laminated is placed on the lamination platform 5, the lamination method further includes:
the membrane 7 to be bonded is adsorbed by adsorption on the bonding platform 5.
After the membrane 7 to be laminated is placed on the lamination platform, in order to avoid the movement of the membrane 7 to be laminated on the lamination platform, the membrane 7 to be laminated needs to be fixed on the lamination platform. In this embodiment, at least one adsorption hole can be formed on the attaching platform, and the membrane 7 to be attached is adsorbed on the attaching platform through the adsorption hole. The position of the adsorption hole on the attaching platform can be symmetrically arranged to ensure the uniformity and compactness of adsorption.
Wherein, the adsorption hole can be connected the evacuation equipment, and the evacuation equipment can be with the diaphragm 7 of waiting to laminate on laminating platform steadily through the mode of adsorption hole evacuation.
Optionally, after nesting the attaching sleeve 6 of the semi-enclosed structure to be attached to the first dummy body 3 and the second dummy body 4, the attaching method further includes:
the first imitation body 3 moves along the surface contacted with the first base 1, so that the first arc-shaped curved surface 321 of the first imitation body 3 is attached to the sleeve body with a semi-enclosed structure at one side of the attaching sleeve; or/and
the second imitation body 4 moves along the surface contacted with the second base 2, so that the second arc-shaped curved surface 421 of the second imitation body 4 is attached to the sleeve body with the semi-enclosed structure at the other side of the attaching sleeve.
It will be appreciated that the first 3 and second 4 imitation forms are identical to the structure of the two sides of the mobile terminal. The structures on two sides of the mobile terminal can be external structures at two opposite ends of the shell of the mobile terminal, and after the attaching sleeves 6 of the semi-enclosed structure to be attached are nested on the first imitation body 3 and the second imitation body 4, the first imitation body 3 and the second imitation body 4 are not necessarily completely and tightly attached to the inner walls of the semi-enclosed structure to be attached. At this time, the first imitation 3 can be controlled to move along the surface contacted with the first base 1, so that the first arc-shaped curved surface 321 of the first imitation 3 is attached to the half-surrounding sleeve body on one side of the attaching sleeve 6; the second copying body 4 can be controlled to move along the surface contacted with the second base 2, so that the second arc-shaped curved surface 421 of the second copying body 4 is attached to the half-surrounding sleeve body on the other side of the attaching sleeve 6. In this way, the bonding process between the membrane 7 to be bonded and the sleeve of the semi-encircling structure can be avoided.
