Description

Technical Field

[0001] This application belongs to the field of circuit board processing technology, specifically a circuit board processing clamping and positioning structure. Background Technology

[0002] With the continuous development of electronic communication technology and the continuous improvement of people's living standards, user terminal devices such as mobile phones, laptops, and tablets are being used more and more commonly in people's daily lives. As the carrier that carries the internal components of the user terminal, the circuit board is the core component of the user terminal device.

[0003] For example, CN212381478U discloses a circuit board processing clamping and positioning structure, including a bottom shell. A clamping mechanism is provided on the top outer wall of the bottom shell, and a support shell communicating with the bottom shell is fixedly connected to one side of the top outer wall. An arc-shaped shell is fixedly connected to the top outer wall of the support shell. The inner arc surface of the arc-shaped shell has evenly distributed air inlets. A filter shell is fixedly connected to the inner side wall of the support shell, and a filtering mechanism is provided inside the filter shell. A crossflow fan is fixedly connected to the inner side wall of the support shell below the filter shell, with the air inlet of the crossflow fan facing the side of the arc-shaped shell. This invention allows the welding fumes generated during circuit board soldering to be drawn into the filter shell by the crossflow fan through the air inlets for filtration. This prevents the welding fumes from drifting and causing harm to workers, prevents the circuit board surface temperature from accumulating and rising during soldering, thus preventing damage to the circuit board, and allows for illumination, preventing the arc-shaped shell from obstructing light.

[0004] However, in this application, the movable clamping block that engages with the clamping screw results in limited adjustment or excessive space occupation due to the excessive length of the clamping screw when dealing with circuit boards of different sizes. Utility Model Content

[0007] By adopting the above technical solution, the device can position and clamp circuit boards of different sizes by setting the threaded rod drive clamping block structure, without occupying a large space.

[0012] In a preferred embodiment, a drawer is movably provided on one side surface of the base, and a pull block is fixedly provided on the surface of the drawer.

[0013] By adopting the above technical solution, the user can pull the pull plate out of the base by holding the pull block, which facilitates subsequent work.

[0014] In a preferred embodiment, a lamp holder is mounted on one end surface of the arc-shaped shell, and a lighting lamp is provided on the surface of the lamp holder.

[0015] By adopting the above technical solution, the lamp holder is designed to facilitate the installation of the lighting lamp, which can then provide illumination.

[0016] In a preferred embodiment, a filter shell is snapped onto one outer surface of the arc-shaped shell, and a crossflow fan is disposed below the filter shell on the surface of the arc-shaped shell.

[0017] By adopting the above technical solution, the crossflow fan can draw in the smoke generated during operation and filter it through the inside of the filter housing.

[0018] In a preferred embodiment, the filter housing has a support strip at the bottom of the inner side of the arc-shaped housing, and a filter screen is provided above the support strip.

[0019] By adopting the above technical solution, the filter shell and support strip can facilitate the installation and fixation of the filter screen, so that the filter screen can perform filtering work better.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, by setting a threaded rod drive clamping block structure, the device can position and clamp circuit boards of different sizes without occupying a large space. The start-up drive motor, together with the fixed plate and bearing block, can cause the slider to slide on the surface of the threaded rod and drive the movable clamping block to move. At the same time, the fixed clamping block can clamp the circuit board between the fixed clamping block and the movable clamping block. Attached Figure Description
