Description

Technical Field

[0001] The utility model relates to the technical field of single-chip computer pin comparison detection, in particular to a single-chip computer pin comparison detection device. Background Art

[0002] Microcontrollers have many pins, including 8-pin and 16-pin. Microcontrollers with different pins can realize different functions. When applying them to products, the functions should be determined first and then the pins with the required functions should be selected. For example, common I / O ports, AD / DA converters, timers and counters, and serial communications are often used in applications. However, there are many uncertainties in the production process that will cause the pin size of the microcontroller to exceed the range, making the microcontroller a defective product, and the pins need to be tested.

[0003] For example, a single-chip microcomputer pin comparison detection device with application number CN201720880241.9 includes a base and at least two detection units and a transmission group, the detection unit includes a single-chip microcomputer fixing slot, a first slide rail, a sliding frame, a reset baffle and several top columns; the two ends of the sliding frame are respectively slidably connected to the two first slide rails, the top column is connected to the sliding frame through the second slide rail, the top column and the sliding frame are arranged vertically, and a displacement sensor is provided on the sliding frame, which is used to detect the relative displacement of the top column and the sliding frame; the reset baffle is fixedly connected to the ends on the same side of the two first slide rails; there are two transmission groups, and the transmission group is used to drive the sliding frame to move horizontally; this utility model is a single-chip microcomputer pin comparison detection device, which can detect whether the length and installation position of the single-chip microcomputer pin meet the specifications, and has the characteristics of simple structure, rapid detection and high working efficiency. However, the detection head of the single-chip microcomputer pin comparison detection device cannot rotate, and fixed detection is performed on a part of the pin. The detection range is relatively small, which easily leads to inaccurate detection results. In addition, the sizes of the single-chip microcomputers are inconsistent, and the position distribution of the lead angles is also different. The single-chip microcomputer pin comparison detection device is difficult to detect different single-chip microcomputers, and its scope of application is small.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a single chip microcomputer pin comparison detection device is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a single chip microcomputer pin comparison detection device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a single-chip microcomputer pin comparison and detection device, comprising a single-chip microcomputer body and a pin sheet, one side of the single-chip microcomputer body is fixedly connected to the pin sheet, and one side of the pin sheet is provided with a nut seat, one side of the nut seat is fixedly connected to a rotating mechanism, and a driving mechanism is provided at the bottom of the single-chip microcomputer body.

[0007] Preferably, the rotating mechanism includes a fixed block fixedly connected to the top position of the nut seat, and one side of the fixed block is fixedly connected to the motor, one side of the nut seat is fixedly connected to the connecting plate, and a rotating rod is provided at the output end of the motor, and one end of the rotating rod is fixedly connected to the detection head.

[0008] Preferably, a lead is provided on one side of the detection head, and a detector is provided at one end of the lead.

[0009] Preferably, the internal thread of the nut seat is connected to a screw rod, and auxiliary rods are provided on the upper and lower sides of the screw rod.

[0010] Preferably, one end of the auxiliary rod is fixedly connected to the outer frame, and the bottom of the nut seat is fixedly connected to the moving block.

[0011] Preferably, the interior of the moving block is movably connected to a double-section threaded rod, and the exterior of the moving block is provided with a driving mechanism.

[0012] Preferably, the driving mechanism includes a passive roller rotatably connected to the external position of the double-section threaded rod, and the external movably connected belt of the passive roller, the internal movably connected belt is connected to the driving roller, and a driver is provided at one end of the driving roller, and a placement rack is provided at the bottom of the driver.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a rotating mechanism and a driving mechanism. When the detection head detects the pin piece, the rotating mechanism drives the detection head to move left and right in the horizontal direction, thereby expanding the detection range of the detection head for the pin piece and avoiding only local detection, which affects the accuracy of the detection result. The driving mechanism drives the detection head inside the outer frame to move. The distance between the two groups of detection heads can be adjusted according to the pin pieces on both sides of the microcontroller body of different sizes, which facilitates close-range detection of the pin pieces and quick adjustment, thereby increasing the practical application range of the utility model.

[0015] 2. The utility model uses the setting of a lead screw and a double-section spiral rod. The lead screw drives the nut seat to move left and right. There is no need for manual control of the detection head. The pin pieces are detected one by one. The detection head moves with the nut seat to ensure that each group of pin pieces on both sides of the microcontroller body is detected. Under the action of the driver, the double-section spiral rod drives the two external groups of moving blocks to move toward the center of the microcontroller body at the same frequency, so that the pin pieces on both sides are detected at the same time.
