Description

Technical Field

[0001] This utility model relates to the field of pressure-holding fixtures, and in particular to a pressure-holding fixture for a laptop touchpad. Background Technology

[0002] In the laptop manufacturing process, when the laptop touchpad is glued to the laptop shell using an adhesive process, the surfaces where the touchpad and the shell are to be bonded must first be cleaned and dust-free, then a high-viscosity adhesive is applied, and then pressure is applied to bond the adhesive layers together.

[0003] In the current laptop manufacturing process, pressing the laptop touchpad with a finger activates the adhesive layer between the bottom of the touchpad and the laptop casing, allowing the adhesive layer to adhere. However, because the area of ​​force applied by pressing with a finger is limited, the adhesive layer may not be fully activated in certain areas. In particular, the edge areas are prone to adhesion failure due to pressure decay. During subsequent use, when subjected to temperature changes or external impacts, the touchpad may peel up due to insufficient adhesive strength. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides, for example Figure 1 - Figure 2 The illustrated notebook computer touchpad pressure-holding fixture includes a pressure-holding fixture base plate 1. The pressure-holding fixture base plate 1 serves as the basic load-bearing structure of the entire fixture, providing an installation platform for other components and directly contacting the notebook computer casing assembly with the touchpad already attached. It transmits the uniform pressure required for pressure holding. During the assembly process, the notebook computer casing assembly is placed on the pressure-holding fixture base plate 1, and its flat surface ensures the initial bonding reference between the touchpad and the casing.

[0016] A pressure-holding fixture protective frame 2 is fixedly connected to the outer peripheral wall of the pressure-holding fixture base plate 1. The pressure-holding fixture protective frame 2 forms a protective boundary to prevent the outer casing assembly from sliding out or being displaced by external forces during operation. At the same time, an auxiliary function module, a bubble level 6, is integrated. The detection mechanism can detect the bubble level 6 during the assembly process to ensure that the laptop outer casing assembly is in a horizontal state when pressed down. The rigid structure of the pressure-holding fixture protective frame 2 restricts the displacement of the outer casing assembly and ensures that the pressure is applied vertically to the touchpad. The fixture can be easily moved through the handle slot 21 to avoid direct contact with the outer casing assembly and thus prevent contamination.

[0017] Positioning posts 22 are fixedly connected to the upper ends of the four corners of the pressure holding fixture protective frame 2. The positioning posts 22 are used to cooperate with the positioning holes of the external pressing equipment to achieve precise alignment between the fixture and the equipment and prevent the fixture from shifting during the pressing process. When the fixture is placed on the press worktable, the positioning posts 22 are inserted into the guide holes of the press to ensure that the position repeatability error of each pressing is less than 0.05mm. The pressure holding fixture base plate 1 is provided with a control board support 3 and a support mechanism 4. The control circuit board under the touch panel is supported by the first hole 31 and the second hole 32 to prevent the circuit board from deforming or short-circuiting during pressing. At the same time, it cooperates with the fixing bolts 5 to achieve detachable replacement. Before pressing, the control circuit board is embedded in the first hole 31 and the second hole 32. The gap between the edge of the circuit board and the hole is controlled within 0.1mm to ensure that the circuit board is subjected to uniform force during pressing.

[0018] Support mechanism 4 is used to support the laptop casing. Support mechanism 4 includes peripheral support member 41 and central support member 42. Both peripheral support member 41 and central support member 42 are mounted on pressure holding fixture base plate 1. Fixing bolts 5 are threadedly connected between control board support member 3, peripheral support member 41, central support member 42 and pressure holding fixture base plate 1. Peripheral support member 41 is distributed around the edge of touchpad, supporting the peripheral area of ​​the casing assembly and preventing edge warping during pressing. Central support member 42 is located at the center directly below the touchpad, providing reverse support. The pressure is balanced by the pressure head to prevent the touchpad from denting due to excessive local pressure. When pressing the laptop touchpad, the peripheral support 41 adopts an L-shaped structure to fit the edge of the shell, and the central support 42 adopts a cylindrical design with a diameter matching the inner ring of the touchpad to ensure uniform pressure distribution. The control board support 3, peripheral support 41, central support 42 and pressure holding fixture base plate 1 are connected by threads to realize modular assembly and quick replacement. When the peripheral support 41 is worn due to long-term use, the fixing bolts 5 can be loosened to replace the new part, reducing maintenance costs.

[0019] The pressure-holding fixture protective frame 2 is provided with a mounting groove 23, and a bubble level 6 is fixedly connected in the mounting groove 23. The bubble level 6 displays the horizontal status of the fixture in real time during the pressure-holding process. The bubble level 6 uses the horizontal bubbles formed by the surface tension of the liquid to determine the horizontal status, preventing uneven pressure distribution caused by fixture tilting. An external detection mechanism can detect the bubble level 6 during the assembly process. When the bubble level 6 malfunctions, the detection mechanism immediately alarms and stops the pressing operation.

[0020] Both sides of the pressure-holding fixture protective frame 2 are provided with hand slots 21, which can be used to easily move the fixture and avoid direct contact with the outer shell components, thus preventing contamination.

[0021] The control board support 3 is provided with a first hole 31 and a second hole 32. The control circuit board under the touch panel is supported by the first hole 31 and the second hole 32 to prevent the circuit board from deforming or short-circuiting during pressing. At the same time, it can be disassembled and replaced in conjunction with the fixing bolt 5. Before pressing, the control circuit board is embedded in the first hole 31 and the second hole 32. The gap between the edge of the circuit board and the hole is controlled within 0.1mm to ensure that the circuit board is subjected to uniform force during pressing.

[0022] The bottom of the pressure-holding fixture base plate 1 is fixedly connected to an anti-slip fixing frame 11. The anti-slip fixing frame 11 increases the friction between the fixture and the worktable, preventing the fixture from sliding during the pressing process. During pressing, the rubber material of the anti-slip fixing frame 11 contacts the worktable, and the coefficient of friction is increased to more than 0.8.

[0023] The pressure holding fixture base plate 1, the pressure holding fixture protective frame 2, and the anti-slip fixing frame 11 are manufactured as a single piece. The single-piece manufacturing structure is stable and has a long service life.

[0024] Example 1: When using this laptop touchpad pressure-holding fixture, first, the fixture is precisely fixed to the corresponding position of the pressing equipment using the positioning post 22 to ensure a stable installation. Then, the C-shell assembly with the touchpad already bonded is placed smoothly inside the fixture. The fixture structure is used to achieve automatic positioning and alignment. The operator presses the start button with both hands at the same time, and the upper mold of the pressing equipment automatically presses down according to the preset parameters, applying uniform pressure to the touchpad to fully activate the backing adhesive. During the pressure holding process, the fixture's support mechanism 4 and the control board support 3 work together to ensure that the assembly does not deform. After the equipment completes the pressing and automatically raises the upper mold, the operator can smoothly remove the product through the hand slots 21 on both sides of the pressure-holding fixture's protective frame 2, completing the entire pressure holding process.

[0025] Example 2: The touch panel is kept horizontal and evenly stressed during the pressing process, which completely solves the problem of edge pressure attenuation caused by finger pressing. The activation rate of the adhesive layer is higher than that of the traditional process. The integrated design of the bubble level 6 and the anti-slip fixing frame 11 further eliminates operation errors and environmental interference. The threaded connection of the fixing bolt 5 shortens the replacement time of worn parts and significantly reduces maintenance costs.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
