Description

Technical Field

[0001] The utility model relates to the technical field of exhaust temperature sensor detection equipment, in particular to an exhaust temperature sensor circuit board function detection equipment. Background Art

[0002] The exhaust temperature sensor is usually installed on the exhaust pipe of an automobile, close to the engine. During production line production, functional testing needs to be carried out after the program is written on the circuit board to confirm whether the PCBA function and program are missed. During detection, the circuit board needs to be firmly clamped to prevent displacement. However, the existing circuit board detection equipment has low applicability to the specification size and cannot ensure centering clamping. Therefore, we designed an exhaust temperature sensor circuit board function detection equipment.

[0003] A Chinese utility model patent with the patent number CN202122872285.6 discloses a multi-functional PCB circuit board detection equipment, including a base. A support frame is connected to the top of the base, and a fixed seat is installed above the inner wall of the support frame. One side of the fixed seat close to the central axis of the base is meshed with a rotating shaft, and a display screen is installed in front of the rotating shaft. An activity frame is arranged below the inner wall of the support frame, and torsion spring shafts are connected to both ends of the activity frame. A first pulling rope is wound around the outer wall of the torsion spring shaft, and the end of the first pulling rope is connected to a first pedal. In this utility model, when people place the PCB circuit board inside the activity frame and step on the second pedal, the second pedal can rotate along the connecting shaft and drive the second pulling rope to pull the moving rod, then the moving rod pulls the spring to extend. Therefore, the crisp sound of metal impact indicates that the pins of the components connected to the circuit board are too long, and this detection work is completed. However, this utility model has the following problems: First, it does not have the function of fixing circuit boards of different specifications, and its applicability is low.

[0022] Embodiment 1

[0023] As Figures 1 to 3 shown, the present utility model provides a function detection device for an exhaust temperature sensor circuit board, including a base 1. The main detection components are all located inside the base 1. A bracket 2 is provided at the rear side of the upper end of the base 1 to limit the downward pressing position of the anti-slip handle 73. And a placement groove 3 is provided at the middle position of the upper end of the base 1. The circuit boards are all detected in the placement groove 3. The bottom of the placement groove 3 is smooth with a small friction coefficient. Adjusting structures 4 are provided on the inner side surfaces of the placement groove 3. The adjusting structure 4 includes an elastic member 41. The elastic member 41 can be a spring structure. One end of the elastic member 41 away from the inner side surface of the placement groove 3 is provided with a clamping plate 42. The clamping plates 42 are abutted end to end to form a rectangular clamping area 43. The circuit board is placed as centered as possible into the rectangular clamping area 43, so that the clamping plates 42 are in contact with the edge of the circuit board, and the elastic member 41 is compressed and contracted, thereby clamping the circuit board stably.

[0024] Further, as Figure 1 shown, two guide rails 5 are symmetrically provided on the left and right sides of the placement groove 3, and the two guide rails 5 are symmetrically arranged front and back to limit the downward movement path of the moving plate 6 and ensure that the pressing rod 64 always presses the circuit board vertically. A limit nut 51 is provided at the upper end of the guide rail 5 to prevent the moving plate 6 from disengaging from the guide rail 5 when moving upward. Thus, the limit nut 51 plays a limiting role, and the outer circumferential surface of the guide rail 5 is sleeved with the moving plate 6.

[0025] Further, as Figure 2As shown, six positioning holes 61 are provided on the surface of the moving plate 6. A shallow groove 62 is provided at the upper end of the positioning hole 61. A fixing member 63 is provided in the groove of the shallow groove 62. The lower end of the fixing member 63 passes through the positioning hole 61 and is connected to a pressure lever 64. The position of the fixing member 63 in the adjustment hole 61 is adjusted according to the characteristics of the circuit board to ensure that the pressure lever 64 can stably limit the position of the circuit board.

[0026] Further, as Figure 1 shown, a vertical connecting rod 7 is provided at the middle position of the upper end of the moving plate 6. Connecting pieces 71 are symmetrically provided on the left and right sides of the upper end of the vertical connecting rod 7. An extension piece 72 is provided at the upper side position between the connecting pieces 71.

[0027] Further, as Figure 3 shown, the rear end of the extension piece 72 is fixedly connected to an anti-slip handle 73. When force is applied to the anti-slip handle 73 by hand, the extension piece 72 is pressed down, so that the connecting piece 71 and the vertical connecting rod 7 drive the moving plate 6 to press down. The anti-slip handle 73 is located at the upper side position of the bracket 2. Two wires 11 are provided between the brackets 2 and are located at the rear side position of the upper end of the base 1. One end of the wire 11 away from the base 1 is provided with a probe 8. The base 1 and the load module are connected together by means of probe wiring.

A protective sleeve 81 is provided outside the probe 8 to protect the probe 8 in the idle state.

[0028] Further, as Figure 1 shown, a power switch 12 is provided at the left front position of the front end of the base 1, and a working switch 13 is provided at the upper right front corner position of the upper end of the base 1.
