This is particularly true for the light guides and LED indicators. Due to light guidance requirements, the distance between the light guides and the LEDs is typically small. Manual assembly during PCBA assembly can lead to collisions between the LEDs and the light guides, damaging them. Summary of the Invention

[0016] (3) Beneficial effects
[0017] Compared with the prior art, the present invention provides a PCBA assembly tool with the following beneficial effects:
[0018] 1. This PCBA assembly tool divides the components to be assembled into a fixed part and a sliding part, and respectively installs the LED indicator workpiece on the sliding part and the shell on the fixed part; compared with the existing technology, manual installation is generally used when assembling PCBAs, which can easily lead to careless installation operations, which may cause the components on the PCBA to collide with the shell, causing damage to the components, especially between the light guide column and the LED indicator. Due to the light guiding requirements, the distance between the light guide column and the LED is generally small. During PCBA assembly, manual operation may cause the LED to collide with the light guide column, thereby causing damage to the LED. During assembly, this device only needs to push the sliding shell along the track, so that the sliding shell slides along the track until it is connected to the fixed shell, and drives the LED indicator workpiece inside the sliding shell to be horizontally inserted into the shell, avoiding collision and reducing damage.

When splicing, it is only necessary to place the circuit board and the outer shell into the sliding shell and the fixed shell according to the limit conditions. Compared with the existing technology that is prone to errors and collisions during manual docking, the installation efficiency is improved and the probability of damage is reduced.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] See also Figure 1-4 , a PCBA assembly tool, including a base 1, a fixed shell 2 and a sliding shell 3 are arranged above the base 1, the fixed shell 2 and the base 1 are fixedly connected, that is, the fixed shell 2 will not move on the upper surface of the base 1, a slide rail 4 is arranged between the sliding shell 3 and the base 1, the sliding shell 3 has the freedom of movement along the direction of the slide rail 4, and the slide rail 4 and the base 1 are fixedly connected; the inner lower surface of the fixed shell 2 and the inner lower surface of the sliding shell 3 are located in the same horizontal plane, ensuring that when the sliding shell 3 and the fixed shell 2 are connected, the inner upper surfaces of the two can be spliced into a complete plane; the fixed shell 2 is connected to the outer shell 5, and the outer shell 5 is installed according to the actual equipment to be installed. In this embodiment, the outer shell 5 is installed inside the fixed shell 2, and a circuit board 6 is placed inside the sliding shell 3. The position of the circuit board 6 corresponds to the outer shell 5. When the sliding shell 3 is connected to the fixed shell 2, the outer shell 5 is sleeved on the outside of the circuit board 6, and the circuit components on the upper surface of the circuit board 6 enter the inner shell 5.
[0027] See also Figure 1-4 A limiting groove 7 is provided on the inner surface of the fixed shell 2, and the limiting groove 7 is provided on the four sides of the inner side of the fixed shell 2. A limiting protrusion 8 is provided on the surface of the outer shell 5, and the shape and position of the limiting groove 7 and the limiting protrusion 8 are adapted to each other; the outer shell 5 is detachably connected to the limiting groove 7 through the limiting protrusion 8, and the outer shell 5 only has the freedom of movement in the up and down directions inside the fixed shell 2 through the limiting protrusion 8, that is, the outer shell 5 will not slide inside the fixed shell 2.
[0028] See also Figure 1-3 The movement direction of the slide rail 4 is parallel to the horizontal plane, and the circuit board 6 is horizontally installed inside the sliding shell 3 to ensure that when the sliding shell 3 is connected to the fixed shell 2, the circuit board 6 can horizontally enter the interior of the shell 5.
[0029] See also Figure 1-2 The slide rail 4 is a linear slide rail 4 or a ball slide rail 4. The slide rail 4 is connected to the sliding shell 3 through a slider. One end of the slider has the freedom of movement along the slide rail 4, and the other end is fixedly connected to the sliding shell 3 by glue or screws. There are two slide rails 4, which are located on both sides of the upper surface of the base 1, so that the sliding shell 3 is more stable when moving.
[0030] See also Figure 3, elevated blocks are provided on both sides of the sliding shell 3, and the circuit board 6 is placed on the elevated blocks. When the circuit board 6 moves toward the fixed shell 2 driven by the sliding shell 3, the circuit board 6 enters the outer shell 5 horizontally; the internal width of the sliding shell 3 is the same as the width of the circuit board 6, so that the internal space of the sliding shell 3 has a limiting effect on the circuit board 6, so that the circuit board 6 will not deviate inside the sliding shell 3 and can accurately enter the inner part of the outer shell 5.
[0031] See also Figure 1-2 An LED indicator workpiece 9 is installed on the circuit board 6, and a light guide column 10 is provided inside the shell 5.

The first magnetic block 11 and the second magnetic block 12 have opposite magnetic poles and attract each other. When the sliding shell 3 approaches the fixed shell 2 along the track, the two attract each other and are fixed, so that the sliding shell 3 and the fixed shell 2 will not separate when the device is in use.
[0033] In summary, compared with the prior art, this PCBA assembly tooling generally uses manual installation when assembling PCBAs, which can easily lead to careless installation operations, which may cause the components on the PCBA to collide with the housing 5, resulting in damage to the components, especially between the light guide column 10 and the LED indicator. Due to the light guiding requirements, the distance between the light guide column 10 and the LED is generally small. During PCBA assembly, due to manual operation, the LED may collide with the light guide column 10, thereby causing damage to the LED. During assembly, this device only needs to push the sliding shell 3 along the track, so that the sliding shell 3 slides along the track until it is connected to the fixed shell 2, and drives the LED indicator workpiece 9 inside the sliding shell 3. It is inserted horizontally into the shell 5 to avoid collision and reduce damage; and the device 2 limits the shell 5 in the fixed shell 2 through the limit block, so that it has and only has the freedom of movement in the vertical direction, and limits the circuit board 6 in the sliding shell 3, and the lower surface of the interior of the fixed shell 2 and the lower surface of the interior of the sliding shell 3 are located on the same horizontal plane, so that the sliding shell 3 can deliver the circuit board 6 into the shell 5 in parallel when it moves, ensuring stability while reducing the difficulty of installation. When splicing, it is only necessary to put the circuit board 6 and the shell 5 into the sliding shell 3 and the fixed shell 2 according to the limit conditions. Compared with the existing technology that is prone to errors and collisions during manual docking, the installation efficiency is improved and the probability of damage is reduced.
