[0002] An integrated circuit is a microelectronic device or component. Using a certain process, components such as transistors, resistors, capacitors, and inductors required in a circuit, as well as wirings, are interconnected and fabricated on a small piece or several small pieces of semiconductor wafers or dielectric substrates, and then encapsulated in a tube shell to form a micro-structure with the required circuit functions. Generally, integrated circuits are installed on circuit boards. As the main body of the integrated circuit, the circuit board plays a crucial role in the assembly process of the integrated circuit.
[0003] When currently detecting an integrated circuit board, a multimeter is usually used to detect the circuit and functions. The operator needs to hold the positive electrode detection pen and the negative electrode detection pen respectively. When the integrated circuit board is damaged, it is necessary to continuously detect each circuit component to determine the damaged component. This operation requires the operator to use both hands simultaneously, resulting in a relatively slow overall detection efficiency. Content of the Utility Model

Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.
[0022] Please refer to Figures 1-3 , a point-touch pen for integrated circuit quality inspection, including a pen housing 1. An installation cavity is formed in the pen housing 1. A left slide plate 12 and a right slide plate 13 are respectively slidably connected in the installation cavity. A left conductive plate 14 and a right conductive plate 15 are respectively fixedly installed on the left slide plate 12 and the right slide plate 13. A display screen 16 is also installed on the pen housing 1; it further includes a variable-distance mechanism. The variable-distance mechanism includes a moving plate 21 slidably connected in the installation cavity. An inclined left guide groove 22 and a right guide groove 23 are formed on the moving plate 21. A left guide rod 24 and a right guide rod 25 are respectively fixedly connected to the left slide plate 12 and the right slide plate 13. The left guide rod 24 and the right guide rod 25 respectively extend into the corresponding left guide groove 22 and right guide groove 23, and the left guide rod 24 is slidably connected to the left guide groove 22, and the right guide rod 25 is slidably connected to the right guide groove 23. A pressing rod 26 slidably connected to the pen housing 1 is fixedly connected to the moving plate 21.
[0023] A single-chip microcomputer is also provided in the pen housing 1. The left conductive plate 14, the right conductive plate 15, and the display screen 16 are all electrically connected to the single-chip microcomputer. The left conductive plate 14 and the right conductive plate 15 are electrically connected to the detection circuit, which are well-known technical means in the art and will not be elaborated.
[0024] Through the provided variable pitch mechanism, the operator pushes the pressing rod 26 to drive the moving plate 21 to move. The movement of the moving plate 21 drives the corresponding left slide plate 12 and right slide plate 13 to move towards each other through the cooperation of the left guide groove 22 and the left guide rod 24 and the right guide groove 23 and the right guide rod 25, so as to clamp both ends of the components on the integrated circuit board to be detected by the left conductive plate 14 and the right conductive plate 15. The detection circuit energizes and detects the components through the left conductive plate 14 and the right conductive plate 15, and processes the detected current through the single-chip microcomputer, and displays the detected current on the display screen 16 for the operator to judge. The utility model can complete the detection operation with one hand, has simple operation, and improves the quality inspection efficiency.
[0025] Further, a control mechanism is further included. The control mechanism includes a plurality of sequentially connected triangular blocks 31 fixedly connected to the pressing rod 26, and locking grooves 32 are formed between adjacent triangular blocks 31. A locking component 33 is further provided on the pen case 1. The locking component 33 includes a fixed block 330 fixedly connected to the pen case 1. A locking rod 331 is slidably connected in the fixed block 330. The end of the locking rod 331 is adapted to the locking groove 32. A first spring 332 is provided between the fixed block 330 and the locking rod 331. The locking rod 331 extends into the locking groove 32 under the action of the first spring 332.
[0026] Due to the setting of the triangular blocks 31, the pressing rod 26 can be pushed unidirectionally. When the left conductive plate 14 and the right conductive plate 15 are in contact with both ends of the component, the locking rod 331 extends into the locking groove 32 under the action of the first spring 332 to lock the pressing rod 26, thereby fixing the left conductive plate 14 and the right conductive plate 15 for convenient detection.
[0027] Further, an unlocking rod 333 is fixedly connected to the locking rod 331. The unlocking rod 333 extends out of the fixed block 330 and is slidably connected to the fixed block 330. By pushing the unlocking rod 333 to drive the locking rod 331 to move, the locking rod 331 is separated from the locking groove 32, so as to facilitate manually pulling out the pressing rod 26 for detecting the next component.
[0028] Further, a second spring 4 is fixedly connected between the end of the moving plate 21 and the side wall of the installation cavity. The second spring 4 is used to reset the position of the pressing rod 26, and it is not necessary for the operator to manually reset the pressing rod 26, which is more convenient for operation.
[0029] Working principle: The operator pushes the pressing rod 26 to drive the moving plate 21 to move. The movement of the moving plate 21 drives the corresponding left slide plate 12 and right slide plate 13 to move towards each other through the cooperation of the left guide groove 22 and the left guide rod 24 and the right guide groove 23 and the right guide rod 25, so as to clamp both ends of the components on the integrated circuit board to be detected by the left conductive plate 14 and the right conductive plate 15. At this time, the locking rod 331 extends into the locking groove 32 under the action of the first spring 332 to fix the left conductive plate 14 and the right conductive plate 15 for easy detection. The detection circuit energizes and detects the components through the left conductive plate 14 and the right conductive plate 15, and processes it through the single-chip microcomputer, and displays the detected current on the display screen 16 for the operator to judge; after the detection is completed, the unlocking rod 333 is pushed to drive the locking rod 331 to move, so that the locking rod 331 is separated from the locking groove 32, and under the action of the second spring 4, the pressing rod 26 automatically resets. The utility model can complete the detection operation with one hand, has simple operation, improves the quality inspection efficiency, and after being proficient, different components can be detected separately with both hands to accelerate the quality inspection efficiency.
[0030] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
