[0004] Regarding the above-mentioned related technologies, the light source board is placed by setting a placement unit, but the distance between the two placement boards is fixed, so only light source boards of a single size can be placed, making the device unable to detect light source boards of different sizes, reducing the applicability of the device. Utility Model Content

[0005] In order to solve the above problems, the present invention provides a light source board testing tool, which adopts the following technical solutions:

[0006] The cam is secured to the upper and lower ends of the cam, and the cam is secured to the lower ends of the cam.

[0007] By adopting the above technical solution, when the equipment is in use, the staff can drive the equipment to move through the driving wheels, which is conducive to improving the convenience of equipment movement. When the equipment is moved to a suitable position, the base is driven to rise through the lifting assembly, and then the base is synchronously raised with the column and the driving wheel, so that the driving wheel is off the ground, which can play a role in supporting and stabilizing the equipment, and can also play a role in adjusting the height of the equipment, making it easier for staff of different heights to operate.

[0008] When the equipment is stabilized, the distance between the two placement plates can be adjusted by adjusting the operation of the components, which is convenient for the equipment to place light source boards of different sizes and to facilitate the equipment to carry out side walls of light source boards of different sizes. When the distance between the two placement plates is adjusted, the staff will place the light source board between the two placement plates. A bearing plate is provided on the top of the base to support the light source board. The two placement plates can clamp the light source. There are power connection plates in the two placement plates to connect the power supply. Then the protective frame is driven down by the first cylinder to cover the light source board, and then the controller is turned on to provide power, so that the light source board emits light. The light generated by the light source board is detected by the photoelectric sensor arranged in the protective frame. When the light source board emits light normally, the warning light emits green light. When the light source board emits light abnormally, the warning light emits red light, which is convenient for the staff to judge.

[0009] Furthermore, the lifting assembly includes two base plates arranged under the base, and two symmetrically distributed second cylinders are fixedly installed on the bottom end of the base, and the ends of the piston shafts of the two second cylinders are fixedly installed with connecting blocks, and the bottom ends of the two connecting blocks are fixedly connected to the top end of the base plate on the same side, and the bottom ends of the two base plates are fixedly installed with anti-slip pads.

[0010] By adopting the above technical solution, when the equipment is moved to a suitable position, the second cylinder drives the connecting blocks and the base plate of the same group to descend, so that the base plate contacts the ground. Then, the base is raised under the driving force of the second cylinder, and the driving wheel is separated from the ground, which can support and stabilize the equipment and help maintain the stability of the equipment.

[0011] Furthermore, the adjustment assembly includes a double-threaded screw rotatably installed in the installation groove, and the side wall of the double-threaded screw is provided with two symmetrically distributed support blocks. The top ends of the two support blocks pass through the base and are fixedly connected to the bottom end of the placement plate on the same side. A mounting box is fixedly installed on one side of the base, and a reduction motor is fixedly installed in the mounting box. One end of the double-threaded screw passes through the base and extends into the mounting box. The double-threaded screw passes through one end of the mounting box and is fixedly connected to the end of the output shaft of the reduction motor.

[0012] By adopting the above technical solution, the double-thread screw is driven to rotate by the reduction motor, and the double-thread screw drives the two support blocks located in the installation groove to move synchronously. The two support blocks move with the placement plate on the same side, which can adjust the distance between the two placement plates, making it convenient for the equipment to place light source boards of different sizes.

[0013] Furthermore, stabilizing blocks are fixedly installed on both sides of the two support blocks, and the inner wall of the installation groove is provided with a stabilizing groove that matches the stabilizing block on the same side.

[0014] By adopting the above technical solution, when the two support blocks slide in the installation grooves, the support blocks slide with the stabilizing blocks in the stabilizing grooves on the same side. The cooperation between the stabilizing blocks and the stabilizing grooves is conducive to maintaining the stability of the support block movement.

[0015] Furthermore, two symmetrically distributed sliders are fixedly mounted on the bottom ends of the two horizontal sections of the placement plates, and a sliding groove matching the sliders on the same side is provided on the top of the base.

[0016] By adopting the above technical solution, when the support block moves with the placement plate on the same side, the placement plate slides with the slider on the same side in the slide groove. The cooperation between the slider and the slide groove is conducive to maintaining the smooth movement of the placement plate.

[0017] Furthermore, a plurality of springs distributed in a linear array are fixedly connected between the opposite side of the two power connection plates and the side opposite to the vertical section of the placement plate on the same side. Two symmetrically distributed limit blocks are fixedly installed at the bottom ends of the two power connection plates, and the top ends of the horizontal sections of the two placement plates are provided with limit grooves that match the limit blocks on the same side.

[0018] By adopting the above technical solution, a spring is provided between the power board and the placement plate on the same side. When the power board and the light source board contact one side opposite to the other, the spring can play a buffering role and is conducive to maintaining the precision of contact between the power board and the light source board. When the power board is located on the top of the placement plate on the same side and slides, the power board slides in the limit groove on the same side with the limit block. The cooperation between the limit block and the limit groove is conducive to maintaining the sliding stability of the power board.

[0019] Furthermore, an observation port is provided on a side of the protection frame away from the vertical section of the support plate, and a protection plate is provided in the observation port.

[0020] By adopting the above technical solution, the protective frame can block the emission of light sources, which helps to prevent workers from being exposed to light for a long time and causing astigmatism in their eyes. An observation port is provided on one side of the protective frame, and a protective plate is provided inside the observation port. The protective plate is made of brown glass, which makes it easy for workers to check the power connection status of the light source board.

[0021] In summary, the present invention has the following beneficial technical effects:

[0022] (1) In the present invention, by adjusting the setting of the component, the double-thread screw is driven to rotate by the reduction motor, and then the two support blocks move synchronously with the placement plates on the same side, which can adjust the distance between the two placement plates, facilitate the placement of light source plates of different sizes for detection, and help to improve the scope of application of the equipment.

[0023] (2) In the present invention, the setting of the driving wheel makes it easy for the staff to adjust the placement of the equipment, and the lifting assembly drives the equipment to rise and fall, thereby making the driving wheel leave the ground, thereby achieving the function of supporting and stabilizing the equipment, and can also play the role of adjusting the height of the equipment, which is convenient for staff of different heights to operate.

[0024] (3) In the present invention, the light source board is firmly clamped by placing a plate, and then the power board is connected to the light source board, so that the light source board can be energized. Then, the protective frame is driven down by the first cylinder and the light source board is covered, which helps to prevent the light source from affecting the staff. The light intensity emitted by the light source board is detected by the photoelectric sensor. When the light source board is emitting light normally, the warning light emits green light. When the light source board is emitting light abnormally, the warning light emits red light, which makes it easier for the staff to make judgments. BRIEF DESCRIPTION OF THE DRAWINGS
