The first positioning substrate 21 is fixedly disposed on the carrier 1 and located at one side of the receiving groove 11 along the X direction. The first positioning movable plate 22 is movably disposed on the carrier 1 and located between the accommodating groove 11 and the first positioning substrate 21, and a gap is formed between the first positioning movable plate 22 and the first positioning substrate 21. The first positioning piece 23 extends from the first positioning flap 22 toward the accommodating groove 11. The middle portion of the first transmission rod 24 is movably inserted into a first through hole (not shown) of the first positioning substrate 21, and one end of the first transmission rod 24 is fixedly connected to the first positioning movable plate 22. Both ends of the first restoring member 25 abut between the first positioning base plate 21 and the first positioning flap 22. A first handle 26 is connected to the other end of the first transfer lever 24.

When the mobile phone middle frame is ready to be installed in the accommodating groove 11, the first driving rod 24, the first positioning movable plate 22 and the first positioning piece 23 can be driven to move away from the accommodating groove 11 by rotating the first handle 26, so that enough space is reserved for installing the mobile phone middle frame, after the mobile phone middle frame is installed in the accommodating groove 11, the first handle 26 is loosened, the first positioning movable plate 22 and the first positioning piece 23 move towards the accommodating groove 11 under the action of the resetting force of the first resetting piece 25, at the moment, the tail end of the first positioning piece 23 extends into the accommodating groove 11 and contacts with the mobile phone middle frame, and the mobile phone middle frame is positioned in the accommodating groove 11.

As shown in fig. 3 and 5, in some embodiments, the first positioning element 23 is rod-shaped, and one end of the first positioning element is fixedly connected to the first positioning movable plate 22, and the other end of the first positioning element is formed into a pointed shape and extends toward the receiving groove 11. Wherein, the first positioning member 23 and the first positioning movable plate 22 may be connected by a fastener.

When the mobile phone middle frame is ready to be installed in the accommodating groove 11, the second handle 36 can be rotated to drive the second transmission rod 34, the second positioning movable plate 32 and the second positioning piece 33 to move away from the accommodating groove 11, so that a sufficient space is reserved for installing the mobile phone middle frame, after the mobile phone middle frame is installed in the accommodating groove 11, the second handle 36 is loosened, the second positioning movable plate 32 and the second positioning piece 33 move towards the accommodating groove 11 under the action of the resetting force of the second resetting piece 35, and at the moment, the tail end of the second positioning piece 33 extends into the accommodating groove 11 and contacts with the mobile phone middle frame, so that the mobile phone middle frame is positioned in the accommodating groove 11. The second transmission rod 34 and the second handle 36 may be connected in the same manner as the first transmission rod 24 and the first handle 26.

Further, similar to the first positioning member 23, the second positioning member 33 may also be rod-shaped, and one end of the second positioning member is fixedly connected to the second positioning movable plate 32, and the other end of the second positioning member is formed to be pointed and extends toward the accommodating groove 11. The mobile phone middle frame may also have a hole-shaped structure on a surface opposite to the second positioning member 33, so that the tip of the second positioning member 33 can be at least partially inserted into the hole-shaped structure to position and fix the mobile phone middle frame, and thus, the second positioning member 33 can limit the displacement of the mobile phone middle frame in the X direction and the Z direction, so as to position the middle frame in the X direction and the Z direction.

In some embodiments, at least one guide rod (not shown) may be disposed between the second positioning base plate 31 and the second positioning movable plate 32, and the guide rod may be disposed in the same manner as the guide rod 27 (refer to fig. 5) between the first positioning base plate 21 and the first positioning movable plate 22 and is used for guiding the clamping movement of the second positioning element 33, which will not be described herein again. In an alternative implementation manner, the second returning element 35 may be a spring, the second returning element 35 may have a plurality of parts, and the second returning element 35 may be sleeved on the second transmission rod 34 and/or the guide rod (referring to the guide rod between the second positioning substrate 31 and the second positioning flap 32) to elastically connect the second positioning substrate 31 and the second positioning flap 32.

As shown in fig. 2 and fig. 3, in some embodiments, the assembly fixture may further include a fixing mechanism 5, the fixing mechanism 5 is mounted on the carrier plate 1, and the fixing mechanism 5 includes a fixing member 54 at least partially located in the receiving groove 11 and movably disposed relative to the receiving groove 11. The fixing member 54 is used for fixing the middle frame of the mobile phone in the accommodating groove 11. For example, referring to fig. 2, the portion of the fixing member 54 located in the accommodating groove 11 is spaced from the groove wall of the accommodating groove 11, so that when the middle frame of the mobile phone is installed in the accommodating groove 11, the fixing member 54 and the groove wall of the accommodating groove 11 can clamp the middle frame of the mobile phone to fix the middle frame of the mobile phone in the accommodating groove 11. It should be understood that the first positioning mechanism 2 and the second positioning mechanism 3 also have the function of fixing the middle frame of the mobile phone, and the middle frame of the mobile phone can be more stably fixed in the accommodating groove 11 by further fixing the middle frame of the mobile phone through the fixing mechanism 5.

As shown in fig. 2-4, further, the fixing mechanism 5 may include an insert 51, a first wedge 52, and a second wedge 53. The insert 51 is embedded in the carrier plate 1, and the insert 5 has an insert groove 511. The first wedge 52 is disposed in the insert pocket 511, one end of the first wedge 52 is elastically connected to a pocket wall of the insert pocket 511 by a first elastic member 81, and the other end of the first wedge 52 has a first inclined surface 521. One end of the second wedge 53 has a second inclined surface 531, one end of the first wedge 52 extends into the insert groove 511 and is slidably connected with the first inclined surface 521 of the first wedge 52 through the second inclined surface 531, and the other end of the second wedge 53 extends out of the carrier plate 1. The fixing member 54 extends from the first wedge 52 toward the receiving groove 11.

With reference to fig. 3, when the middle frame of the mobile phone is ready to be installed in the accommodating groove 11, the bottom end of the second wedge 53 is firstly pulled, so that the first wedge 52 moves under the sliding fit of the wedge surfaces of the first inclined surface 521 and the second inclined surface 531, and the fixing member 54 can be driven to move synchronously, so that the distance between the fixing member 54 and the groove wall of the accommodating groove 11 is increased, and a sufficient space is made for the middle frame of the mobile phone to be installed in the accommodating groove 11, and in the process, the movement of the first wedge 52 compresses the first elastic member 81. After the middle frame of the mobile phone is installed in the accommodating groove 11, the force applied to the second wedge 53 is removed, so that the first wedge 52 drives the fixing member 54 to move synchronously under the action of the restoring force of the first elastic member 81, and the distance between the fixing member 54 and the wall of the accommodating groove 11 is reduced, thereby clamping the middle frame of the mobile phone in the accommodating groove 11. Therefore, only the part of the second wedge block 53 extending out of the carrier plate 1 needs to be stirred, so that the fixing mechanism 5 can be operated to loosen or clamp, the operation is convenient and flexible, and the operation efficiency can be effectively improved in the production process.

The fixing mechanisms 5 may be provided in plurality, and the plurality of fixing mechanisms 5 may be respectively embedded at different positions of the carrier plate 1, so that the fixing member 54 of each fixing mechanism 5 may fix different positions of the middle frame of the mobile phone, thereby fixing the middle frame of the mobile phone more firmly.

In particular, in this embodiment, the first positioning mechanism 2 includes two first positioning members 23, and the third positioning mechanism 2' includes one first positioning member 23, so that not only can the mobile phone middle frame be clamped and fixed from both sides, but also the risk that the mobile phone middle frame rotates when being clamped can be avoided by the two first positioning members 23 of the first positioning mechanism 2. Moreover, the plurality of first positioning pieces 23 on the first positioning mechanism 2 are driven by one first handle 26 together, so that the operation is quicker, and the third positioning mechanism 2' is driven by only one handle, so that the operation efficiency is improved.

As shown in fig. 8, in some embodiments, the assembly fixture further includes a fourth positioning mechanism 3 ', and the fourth positioning mechanism 3' is disposed on the carrier plate 1 and located on the other side of the accommodating groove 11 opposite to the second positioning mechanism 3. The fourth positioning mechanism 3' may have the same structure as the second positioning mechanism 3, and is used for clamping and fixing the middle frame of the mobile phone together with the second positioning mechanism 3. In particular, in the present embodiment, the second positioning mechanism 3 includes a second positioning substrate 31, two second positioning members 33, two second positioning movable plates 32, two second transmission rods 34 and two second handles 36 are disposed on the second positioning substrate 31, and the two positioning members are disposed on two sides of the second positioning substrate 31 respectively, and each second positioning member 33 is driven by the respective second handle 36, which can avoid the risk of rotation of the middle frame of the mobile phone when the middle frame of the mobile phone is clamped, and can also make the clamping of the middle frame of the mobile phone along the Y direction more stable.

In this embodiment, the stop block 391 is located between the accommodating groove 11 and the fourth positioning mechanism 3', and the fixing element 54 moves relative to the accommodating groove 11 and also relative to the stop block 391. Specifically, when the middle frame of the mobile phone is installed in the accommodating groove 11, the second wedge 53 of the fixing mechanism 5 can be driven to drive the first wedge 52 to move, and further the fixing member 54 is driven to move away from the stop block 391, so that a sufficient space is left for installing the middle frame of the mobile phone. After the middle frame of the mobile phone enters the receiving groove 11, the second wedge 53 is released, the first wedge 52 is reset under the action of the first elastic element 81, and the fixing element 54 is driven to move towards the stop block 391.

As shown in fig. 8-12, in some embodiments, the positioning device further includes a third wedge 37 and a fourth wedge 38. The third wedge 37 is partially movably inserted into a first via hole (not shown) of the second positioning substrate 31, the third wedge 37 has a third inclined surface 371, and one end of the third wedge 37 is fixedly connected to the pushing block 39.

The third elastic member 83 is abutted between the pressing block 72 and the driven member 71, and when the driven member 71 is pressed against the pressing plate 4, the driven member 71 can elastically press the pressing plate 4 based on the third elastic member 83 according to the thickness and other sizes of the product, so that the product is prevented from being crushed due to excessive pressing force. For example, when the product is thick, the pressing of the driven member 71 on the pressing plate 4 compresses the third elastic member 83 upward so that the flexibility self-adjusts the pressing force, which can effectively protect the product while pressing.

As shown in fig. 15, in the present embodiment, two first pressing blocks 72 are disposed on one handle 7, the two first pressing blocks 72 are respectively disposed on two sides of the handle 7, and each first pressing block 72 is respectively pressed with two driven members 71 by two third elastic members 83 in a floating manner. In addition, a second pressing piece 72' is provided in the middle of the handle 7, and functions as the first pressing piece 72, and a driven piece 71 is floatingly pressed by a third elastic piece 83. The second pressure piece 72' differs from the first pressure piece 72 in that they have different shapes and they each press a different number of the driven pieces 71. Therefore, the floatable receiving parts 71 on the lifting handle 7 can more stably and safely compress the pressing plate 4, and further play a role in fixing the mobile phone middle frame and the glass screen in the boiler pressure maintaining process.

As shown in fig. 15, in some embodiments, the handle 7 has a pressing groove 7c, one end of the first slot 7a communicates with the pressing groove 7c, the first pressing piece 72 is disposed in the pressing groove 7c and is flush with the surface of the handle 72, and the driven piece 71 is disposed at the other end of the first slot 7 a.
