Technical Field
[0001] The utility model relates to the technical field of circuit boards, and more particularly to a circuit board detection jig. Background Art
[0002] A circuit board, also known as a printed circuit board or PCB, is a fixed design board used to connect electronic components, connectors, and conductive lines. It is made of conductive material, usually an insulating base material covered with copper foil. Before the advent of circuit boards, the interconnection between electronic components relied on wires to form a complete circuit. With the continuous development of electronic products, circuit board manufacturing technology has also continued to develop. Circuit boards are an important component of electronic equipment, and their quality affects the quality of the entire device. Therefore, after the circuit boards are produced, they usually need to be tested.
[0003] Shortcomings of the existing technology: After the circuit board is produced in the existing technology, the staff is usually required to place the circuit board in the testing equipment, and then take it out after the test is completed, and repeat this operation. At the same time, the monitoring fixture in the existing technology usually transports and moves the circuit board through a conveyor belt, but this movement method cannot fix the position of the circuit board, which can easily cause the circuit board to shift in position during the movement or testing process, affecting the test results of the circuit board. Utility Model Content

[0010] Preferably, the top rectangular array of the four guide rods is fixedly connected to the bottom end of the fixed plate.
[0011] Technical effects and advantages of this utility model:
[0012] 1. The utility model is equipped with a conveyor to transport the circuit board that needs to be inspected, and the circuit board is moved to the bottom of the inspection component. The quality of the circuit board is inspected by the inspection component. The electric telescopic rod pushes the limit plate up and down. The limit plate moves downward, causing the inspection module to move downward as well.

DETAILED DESCRIPTION
[0019] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The circuit board inspection fixture involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0020] The utility model provides a circuit board detection fixture, such as Figure 1 As shown, it includes a workbench 1, four mounting seats 2 are fixedly installed in a rectangular array on the top of the workbench 1, a conveyor 3 is fixedly installed between the four mounting seats 2, the conveyor 3 is located at the top of the workbench 1, and the stability of the conveyor 3 during operation is ensured by the mounting seats 2, a support plate 4 is fixedly installed on the rear side of the top of the workbench 1, an L-shaped support frame 5 is fixedly installed on the front side of the top of the workbench 1, a connecting block 6 is fixedly installed on the middle of the inner wall of the L-shaped support frame 5, and a fixing plate 7 is fixedly connected to the rear end of the connecting block 6, and the tightness of the connection between the fixing plate 7 and the L-shaped support frame 5 is ensured by the connecting block 6. A detection component 8 is fixedly installed on the top of the inner cavity of the support frame 5, and the stability of the detection component 8 during operation is increased by the fixing plate 7. A cylinder 9 is fixedly installed on the top of the support plate 4, and a positioning plate 10 is fixedly connected to the output end of the cylinder 9. The positioning plate 10 is pushed to move by the cylinder 9. The positioning plate 10 is located on the top surface of the conveyor 3. The positioning plate 10 is L-shaped. The circuit board moved to the bottom of the detection component 8 is fixed at a right angle to the L-shaped positioning plate 10 to ensure the accuracy of the position between the circuit board and the detection component 8, and to avoid the circuit board from being offset during the movement or detection process, thereby affecting the detection results.
[0021] Further, such as Figure 2 As shown, the detection component 8 includes an electric telescopic rod 81, the bottom end of the electric telescopic rod 81 is fixedly connected to a limit plate 82, and the limit plate 82 is moved up and down by the electric telescopic rod 81. Four sliding sleeves 83 are fixedly installed in a rectangular array on the top of the limit plate 82, and the inner cavity of the sliding sleeve 83 is movably connected to a guide rod 84. The bottom end of the limit plate 82 is fixedly connected to a detection module 85, and the bottom end of the detection module 85 is fixedly connected to multiple detection probes 86 at equal distances. The circuit board is detected by the detection module 85 and the detection probe 86.
[0022] Further, such as Figure 3 and Figure 4 As shown, the top end of the electric telescopic rod 81 is fixedly connected to the top end of the inner cavity of the L-shaped support frame 5, and the electric telescopic rod 81 is fixed by the L-shaped support frame 5. The bottom end of the electric telescopic rod 81 passes through the middle of the fixed plate 7 and is fixedly connected to the top end of the limit plate 82. The limit plate 82 is located below the fixed plate 7. When the circuit board is fixed by the positioning plate 10, it moves downward through the limit plate 82, so that the detection probe 86 contacts the surface of the circuit board for detection.
[0023] Furthermore, the rectangular array at the top of the four guide rods 84 is fixedly connected to the bottom of the fixed plate 7. When the limit plate 82 drives the detection module 85 and the detection probe 86 to move downward, uneven pressure is likely to occur. The guide rods 84 make the downward pressure of the detection module 85 uniform, avoiding damage to the circuit board.
[0024] The working principle of the utility model is as follows: first, the circuit board to be inspected is placed on the top of the conveyor 3, and the circuit board is moved to the bottom of the inspection component 8 through the conveyor 3. At this time, the cylinder 9 is started, and the positioning plate 10 is pushed to move by the cylinder 9. The positioning plate 10 is L-shaped. The circuit board moved to the bottom of the inspection component 8 is fixed at a right angle to the L-shaped positioning plate 10 to ensure the accuracy of the position between the circuit board and the inspection component 8, and to avoid the circuit board from deviating during the movement or inspection process, which affects the inspection result. After it is fixed, the electric telescopic rod 81 pushes the limit plate 82 When the limit plate 82 drives the detection module 85 and the detection probe 86 to move downward, the guide rod 84 makes the downward pressure of the detection module 85 uniform to avoid damage to the circuit board. The limit plate 82 moves downward so that the detection probe 86 contacts the surface of the circuit board for detection. The data obtained by the detection is received and processed by the detection module 85. After the detection is completed, the electric telescopic rod 81 enables the limit plate 82 to drive the detection module 85 and the detection probe 86 to move upward, and the cylinder 9 retracts the positioning plate 10, which is transported by the conveyor 3 and moved to the next process.
