Description

Technical Field

[0001] The present invention relates to the technical field of resistance detection, and specifically to a patch resistor performance detection device. Background Art

[0002] A patch resistor is a type of metal glaze resistor, which is made by mixing metal powder and glass glaze powder and printing it on a substrate using screen printing method2. It is usually made of a ceramic or metal sheet, covered with a resistive material to control the resistance value. At both ends of the patch resistor, there are welding or metal layers for connecting to the pads on the circuit board.

[0003] According to a patch resistor high-temperature detection device disclosed in Application No. 202410969345.1, it includes an L-shaped base and a feeding component, a feeding component, a discharging component, a detection component and a driving component installed on the L-shaped base. There are multiple resistor placement cavities inside the feeding component, and multiple connected guide grooves and detection ports are respectively arranged on the upper and lower parts of the feeding component. The discharging component includes multiple inclined openings arranged.

[0004] The above detection device can connect the patch resistor to the contact for detection, and at the same time, a heating device can be used to heat and detect the patch resistor to enhance the detection effect. However, the above contacts are not stored and are exposed to the air during use. Dust in the air adheres to the contacts. Dust is usually non-conductive. When it adheres to the contacts, it will form an isolation layer between the contacts and the patch resistor, increasing the contact resistance. This may lead to poor current transmission, causing deviations in the detected resistance value, and even may not be able to accurately measure the resistance value due to poor contact. To solve the above problems, the present invention proposes a patch resistor performance detection device. Summary of the Invention

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] As Figures 1 - 8 shown, the present invention provides the following technical solutions: Embodiment 1: A patch resistor performance detection device, including a base 1, a fixed block 2 is fixedly connected to the upper surface of the base 1, a bracket 3 is fixedly connected to the outer wall of one side of the fixed block 2, a heating lamp 4 is fixedly connected to the outer wall of one end of the bracket 3, an adjustment mechanism 5 is provided on one side of the fixed block 2, and a clamping mechanism 6 is provided above the base 1; The adjustment mechanism 5 includes a support block 51, a chute is equidistantly penetrated through the outer wall of one side of the fixed block 2, a slider 52 is slidably connected to the inner wall of the chute, one end of the slider 52 extends outside the chute and is fixedly connected to the support block 51, a cavity is penetrated through the inside of the support block 51, a limit block 53 is slidably connected to the inner wall of the cavity, a limit hole 54 is penetrated through the outer wall of one side of the support block 51, one end of the limit block 53 penetrates and extends into the limit hole 54, an auxiliary block 55 is fixedly connected to the upper end of the support block 51, a blocking block 56 is slidably connected to the inner wall of the chute, a sliding cavity is penetrated through the inside of the blocking block 56 and the slider 52, a triangular block 57 is slidably connected to the inner wall of the sliding cavity, and triangular holes 58 are equidistantly penetrated through the inner wall of the chute, and the triangular block 57 penetrates and extends into the triangular holes 58; The supporting mechanism 6 includes a cleaning block 61, and a plurality of mounting holes are equidistantly provided on the upper surface of the support block 51. The inner walls of the mounting holes are slidably connected to the cleaning blocks 61, and the inner bottom walls of the mounting holes are symmetrically fixedly connected to the contacts 62. The interior of the support block 51 is symmetrically provided with movable grooves relative to the mounting holes, and the inner walls of the movable grooves are slidably connected to conical blocks 63, which abut against the cleaning block 61. The interior of the support block 51 is provided with a pushing groove below the movable groove, and the inner wall of the pushing groove is slidably connected to a slide rod 64, and the outer wall of the slide rod 64 is fixedly connected to a triangular push block 65 relative to the position of the conical block 63, and one end of the triangular push block 64 abuts against the conical block 63.

[0021] In use, the drive motor 10, the heating lamp 4 and the display 16 are all connected to an external drive source through a controller. The contact 62 and the display 16 are both connected to a detection device. The handle 15 is used to pull the slide bar 64 and the triangular push block 65 to move outward. The triangular push block 65 pushes the tapered block 63 to move outward. The tapered block 63 moves in the moving groove and compresses the third spring 14. At this time, the cleaning block 61 moves downward in the mounting hole, exposing the mounting hole. The chip resistor to be detected can be inserted into the mounting hole. The chip resistor abuts against the contact 62, and the contact 62 connects the chip resistor into the measurement circuit. Using the principle of bridge balance, the resistance value of the chip resistor is converted into a measurable electrical signal, such as a voltage or current signal. Then, by measuring this electrical signal, the resistance value of the resistor is determined. The display 16 converts the received electrical signal into a digital signal for display. Personnel can detect the performance of the chip resistor through the display 16. The T-shaped slider 12 can be moved outward, and the T-shaped slider 12 compresses the second spring 13. The T-shaped slider 12 can be used to drive the blocking block 56 to move upward. According to the temperature to be heated, the blocking block 56 is moved to the required position. After adjustment, the fourth spring 17 pushes the triangular block 57 to move into the triangular hole 58 to limit and fix the blocking block 56. When the T-shaped slider 12 is released, the second spring 13 pushes the T-shaped slider 12 to squeeze the fourth spring 17, increasing the elastic force of the fourth spring 17. The drive motor 8 is started to drive the drive rod 9 and the drive gear 10 to rotate. The drive gear 10 drives the rack 7 and the support block 51 to move upward, adjusting the height of the support block 51. The support block 51 drives the support block 51 on one side to move upward synchronously through the limit block 53, adjusting the height of the support block 51 until the support block 51 abuts against the blocking block 56, moving the support block 51 to the required position. According to the different distances between the support block 51 and the heating lamp 4, the heating effect of the chip resistor is adjusted. The heating lamp 4 heats the chip resistor, and it is observed whether there are abnormal phenomena such as overheating, smoking, and strange smells in the resistor. After the detection is completed, the drive motor 8 is started to drive the drive rod 9 to rotate in the reverse direction, so that the support block 51 moves downward. The support block 51 drives other support blocks 51 to move downward synchronously through the auxiliary block 55. The first spring 11 pushes the limit block 53 to move into the limit hole 54 to connect the support block 51. When the chip resistor needs to be taken out, the handle 15 is used to push the slide bar 64 and the triangular push block 65 inward. The second spring 13 pushes the tapered block 63 to move inward. The tapered block 63 pushes the cleaning block 61 and the chip resistor to move upward, moving the chip resistor out of the storage hole.
