Description

Technical Field

[0001] This utility model relates to the field of pressing fixture technology, specifically a pressing fixture for mobile phone motherboards. Background Technology

[0002] A mobile phone motherboard pressing fixture is a tool used to fix and press mobile phone motherboards during the manufacturing process;

[0003] For example, the Chinese authorized patent with announcement number CN213288987U (A 5G mobile phone motherboard two-in-one pressing fixture): includes a base plate and a cover, the cover being pressed and connected to the base plate. The base plate is provided with a fixing block and a fixing groove for placing the motherboard. The cover is fixed to the base plate by the fixing block. The fixing groove is provided with spring clips for fixing the mobile phone motherboard around its perimeter. A counterweight is fixed below the cover, the counterweight is located above the fixing groove, and several pressing posts for pressing the motherboard are provided at the lower edge of the counterweight. This utility model places the mobile phone motherboard with components in the fixing groove, positions and fixes the mobile phone motherboard by spring clips, and then presses the mobile phone motherboard by the counterweight. This can ensure that the mobile phone motherboard will not shift position and cause open soldering when passing through the reflow oven, and can also prevent the mobile phone motherboard from bending or warping.

[0004] However, existing mobile phone motherboards are designed with one base plate corresponding to one size of motherboard. Placing motherboards of different sizes can easily lead to positional misalignment, or even require replacing the base plate, resulting in poor applicability. Furthermore, the motherboards are pressed and fixed by clamping posts during the pressing process, which is time-consuming and laborious, resulting in poor flexibility. Therefore, this design does not meet the current requirements. To address this, we propose a mobile phone motherboard pressing fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile phone motherboard pressing fixture to solve the problems mentioned in the background art. When placing existing mobile phone motherboards, one base plate corresponds to one size of mobile phone motherboard. Placing mobile phone motherboards of different sizes can easily lead to positional misalignment, or even replacement of the base plate, resulting in poor applicability. Furthermore, when pressing the mobile phone motherboard, it is fixed by pressing down with clamping columns, which is time-consuming and laborious when installing and removing the mobile phone motherboard, resulting in poor flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile phone motherboard pressing fixture, comprising: a base, wherein the base has an installation cavity inside, and the top of the installation cavity is open, a pressing component is provided at the upper end of the installation cavity, a connecting groove is provided on the inner wall of the installation cavity, and multiple connecting grooves are provided, and a limit strip is provided on one side of the connecting groove, and multiple limit strips are provided.

[0007] Preferably, a connecting seat is provided on one side of the limiting strip, and the connecting seat is inserted along the connecting groove, and both the connecting seat and the connecting groove are T-shaped.

[0008] Preferably, the pressing assembly includes a lower pressing seat, a fixed top plate is provided above the lower pressing seat, a guide sleeve is provided at the center of the upper surface of the lower pressing seat, a guide groove is provided inside the guide sleeve, a guide post is provided at the center of the lower surface of the fixed top plate, and the guide post moves up and down along the guide groove, and a force application frame is provided on the upper surface of the lower pressing seat near the front end.

[0009] Preferably, compression springs are provided on both sides of the guide sleeve, a first spring fixing seat is provided at the lower end of the compression spring, and a second spring fixing seat is provided at the upper end of the compression spring. The first spring fixing seat and the second spring fixing seat are welded and fixed to the lower pressure seat and the fixed top plate, respectively.

[0010] Preferably, the rear surface of the fixed top plate is provided with a fixing frame, one end of the fixing frame is provided with a mounting hole, and the fixing frame is fixed to the base by external bolts through the mounting hole.

[0011] Preferably, the pressing assembly further includes a lower pressing base plate, the upper surface of which is provided with a stabilizing insert plate, and the lower surface of the lower pressing base is provided with a stabilizing slot, wherein the stabilizing insert plate is inserted into the stabilizing slot and fixed by external fixing adhesive.

[0012] Preferably, the base has fixing plates on both the front and rear surfaces of its bottom sides, and the fixing plates are welded to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a compression spring between the lower pressure seat and the fixed top plate, and sets a limiting strip inside the mounting cavity. Different sizes of limiting strips are selected according to the size of the mobile phone motherboard, which facilitates the limiting and fixing of mobile phone motherboards of different sizes. When installing the limiting strip, the connecting seat is inserted along the connecting groove. Since the connecting seat and the connecting groove are both T-shaped, the connection stability of the limiting strip is improved and it is not easy to slip off. After the mobile phone motherboard is placed, the lower pressure seat is moved down by the elasticity of the compression spring to press the mobile phone motherboard. The operation is simple and convenient, improving the convenience of operation. It solves the problem that when placing the existing mobile phone motherboard, one base plate corresponds to one size of mobile phone motherboard. When placing mobile phone motherboards of different sizes, the position is easily offset, or even the base plate needs to be replaced, resulting in poor applicability. In addition, when the mobile phone motherboard is pressed and fixed by the pressing column, it is time-consuming and laborious to install and remove the mobile phone motherboard, resulting in poor flexibility.

[0015] (2) By setting a stabilizing slot on the lower surface of the pressure seat and a stabilizing insert plate on the upper surface of the pressure base plate, the stabilizing insert plate is inserted into the stabilizing slot, so that the pressure base plate can be detached. After the surface of the pressure base plate is damaged by friction after long-term use, the pressure base plate can be replaced independently through the detachable pressure base plate, without having to replace the entire pressure seat, thus reducing replacement costs.

Figure 1 As shown, the upward lifting of the force application frame 16 causes the lower pressure seat 8 to move upward, deforming the compression spring 10 and causing the lower pressure seat 8 to leave the mounting cavity 4, exposing space for easy installation of the mobile phone motherboard. When the lower pressure seat 8 moves, the guide post 13 along the guide groove 15 improves the stability of the movement of the lower pressure seat 8 and prevents positional deviation. The mobile phone motherboard is placed inside the space composed of multiple limit bars 5, and the limit bars 5 squeeze and limit the mobile phone motherboard. Then the force application frame 16 is released, and the elasticity of the compression spring 10 causes the lower pressure seat 8 to move downward, performing a pressing operation on the mobile phone motherboard.
