Description

Technical Field

[0001] The utility model relates to the technical field of mouse, in particular to a mouse IC component. Background Art

[0002] With the development of electronic technology, electronic computers have become an indispensable tool in our lives and offices. Among them, the mouse, as the main input device of electronic computers, has a great impact on our operating efficiency. In the earliest years, mechanical mice were used. The principle of mechanical mice is to use conductive rubber rollers and negative electric positioning axes to position and move, but the accuracy of mechanical mice is too poor, so they were eliminated. Nowadays, the most common one should be the optical mouse. Its working principle is to receive the reflected light through the light source body and reflect it to the optical sensor (sensing chip). Among them, the optical sensor (sensing chip), optical lens and light source body are essential components of the optical mouse. The industry generally integrates these three components into one, also known as a three-in-one integrated IC or IC component.

[0003] Traditional optical mice generally solder IC components to PCB boards through hardware components, which require tinning. When the IC components enter the tin furnace, the tin liquid has a certain buoyancy, which will lift the IC components and cause them to deviate from the predetermined welding position. Therefore, in the traditional soldering process, specific fixtures are required to assist in soldering, which has low applicability and high cost. In addition, traditional IC components directly expose the optical lens to the outside, which is easily burned by hot air during the soldering process. The convex surface of the optical imaging is easily fogged and blurred, resulting in poor IC soldering effect or even loss of function. In daily use, the optical lens is also easily affected by the outside world, resulting in a reduced service life. Utility Model Content

[0005] Technical solution: To achieve the above purpose, the mouse IC component of the utility model is provided with a PCB board and an IC component, wherein the IC component is provided with an IC upper cover and an IC fixed bottom shell, and the IC upper cover is connected to the IC fixed bottom shell;

[0006] The IC upper cover is provided with a plastic shell, the plastic shell is connected to the IC fixed bottom shell, and a wick and a sensor chip are installed at the bottom of the plastic shell;

[0007] A lens assembly is installed above the IC fixed bottom shell, a light isolation sheet is installed above the lens assembly, and a light transmission hole and a light filtering hole are opened at the bottom of the IC fixed bottom shell.

[0008] Furthermore, the lens assembly is provided with an arc-shaped lens portion and a convex lens portion, a light-isolating sheet is installed between the arc-shaped lens portion and the convex lens portion, the arc-shaped lens portion and the convex lens portion are separated by the light-isolating sheet, and the wick and the sensing chip are separated by the light-isolating sheet.

[0009] Furthermore, the position of the wick corresponds to the arc-shaped lens portion, the position of the sensor chip corresponds to the convex lens portion, the arc-shaped lens portion is located above the light-transmitting hole, and the convex lens portion is located above the light-filtering hole.

[0010] Furthermore, the light-isolating sheet is provided with a blocking portion, a wick passing hole is provided on one side of the blocking portion, and a light-filtering light-transmitting hole is provided on the other side.

[0011] Furthermore, hooks are fixedly connected on both sides of the IC fixed bottom shell, and the bottom of the IC fixed bottom shell is also covered with a heat insulation film. The hooks are connected to the bottom of the PCB board to fix the IC fixed bottom shell to prevent the IC fixed bottom shell from shifting under the action of buoyancy.

[0012] Furthermore, a plurality of hardware components are fixedly connected to the periphery of the plastic shell, and the hardware components are fixedly connected to the PCB board.

[0013] The beneficial effects of the utility model are:

[0015] 2. In the utility model, by setting the lens assembly in the IC fixed bottom shell, the heat insulation film is used to isolate the hot air from the outside when entering the tin furnace, thereby avoiding the risk of burns caused by hot air, the optical imaging convex surface is easily fogged and blurred, resulting in poor IC passing effect, or even loss of function. In addition, because the lens assembly is set inside, the contact with the outside world is reduced, and the service life is also greatly increased. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A lamp wick 22 and a sensor chip 23 are installed at the bottom of the plastic shell 21, a light transmission hole 31 and a light filtering hole 32 are opened at the bottom of the IC fixed bottom shell 3, and the bottom of the IC fixed bottom shell 3 is also covered with a heat insulation film 34.

A lamp wick transmission hole 52 is opened on one side of the blocking portion 51, and a light filtering light transmission hole 53 is opened on the other side. The arc lens portion 41 and the convex lens portion 41 are connected to each other. The mirror portion 42 is separated by a blocking portion 51, the wick 22 and the sensing chip 23 are separated by the blocking portion 51, the wick 22 is arranged above the arc lens portion 41, the sensing chip 23 is arranged above the convex lens portion 42, the arc lens portion 41 is located above the light transmission hole 31, the convex lens portion 42 is located above the filter hole 32, the wick transmission hole 52 is arranged between the wick 22 and the arc lens portion 41, and the filter transmission hole 53 is arranged between the convex lens portion 42 and the sensing chip 23.

[0031] The operating principle of the mouse IC component:

[0032] During soldering, the mouse IC component enters the solder furnace, and the hook 33 on the IC fixed bottom shell 3 fixes the IC fixed bottom shell 3. The mouse IC component will not be lifted up due to the buoyancy of the tin liquid, resulting in deviation.

[0033] When in use, the flash light emitted by the wick 22 passes through the arc lens portion 41 to the desktop, and then is reflected by the desktop to the filter hole 32 on the IC fixed bottom shell 3 to collect the effective light onto the convex lens portion 42, and then the image is transmitted to the sensing chip 23 through the convex lens, thereby producing different image change principles.
