Embodiment Construction
[0017] Such as figure 1 , figure 2 and image 3 As shown, a detection fixture for detecting the main control board provided by the present invention includes a workbench 1 provided with a control system. The workbench is composed of a casing 1b and a top cover 1a thereof. Connected through hinges, the top cover 1a is provided with a parameter display 2 and an alarm 13 that are connected with the control system, a support frame 3 is also provided on the top cover, a connection seat 6 is provided on the upper part of the support frame, and a positioning device is provided at the lower end of the connection seat. The upper end of the sleeve 8 is provided with a bending handle 5 which is hingedly connected with it, and a splint 4 is respectively connected to both sides of the bending handle. , the push rod is inserted into the positioning sleeve, and is matched with the positioning sleeve. The lower end of the push rod is connected with a push plate 10. The top cover on one sid...

The invention relates to a detection jig for detection of a master control board. The detection jig is characterized by comprising a bench provided with a control system, a support is arranged on the bench, a connector is arranged on the upper portion of the support, a positioning sleeve is arranged at the lower end of the connector, a bent handle is hinged to the upper end of the connector, two clamp plates are connected to two sides of the bent handle respectively, one end of every clamp plate is hinged to a bent segment of the bent handle, the other end of every clamp plate is connected with a push rod, the push rod is in clearance fit with the positioning sleeve, a push plate is connected to the lower end of the push rod, pressure rods in a group are evenly distributed at the bottom of the push plate, a lift holder used for holding the master control board is arranged on the bench right under the pressure rods, probes in a group in connected fit with the control system are arranged on the bench right under the lift holder, and a closed loop forms once contacts or pins of the master control board are in contact with the probes. The detection jig has the advantages that the structure is simple, operations are convenient, the master control board can be detected more efficiently and precisely, labor intensity is reduced for staff, and maintenance is facilitated.
Description
technical field [0001] The invention relates to the technical field of detection equipment, in particular to a detection jig for a main control board of an electric pencil sharpener. Background technique [0002] As the core component of electrical products, the main control panel directly determines the qualification rate of electrical products. Therefore, the main control board needs to be tested before the whole machine is assembled. However, the existing main control board mostly uses manual methods to detect whether each part of the main control board circuit can meet the design parameter requirements, the detection speed is slow, the detection accuracy is low, and it cannot meet the needs of rapid detection, resulting in relatively low work efficiency. It has brought difficulties to large-scale integrated production of enterprises. Contents of the invention [0003] The purpose of the present invention is to solve the problems of slow speed and low precision of the...
