Description
Technical Field
[0001] This invention relates to the field of resistance testing technology, and more specifically to a resistance testing device for alloy resistors. Background Technology
[0002] Alloy resistor resistance testing equipment mainly adopts a dual-wire testing method, which simultaneously applies excitation current and acquires voltage signals through two wires to quickly measure the resistance value of alloy resistors. It has a simple structure and is easy to operate, making it suitable for routine resistance testing scenarios where high measurement accuracy is not required. It can meet the resistance screening needs in general production and inspection processes.
[0003] Chinese patent CN119125675B discloses a resistance testing device for alloy resistors, relating to the technical field of resistance testing equipment. This device includes: a support testing main body, a lifting mechanism, a probe component, a reciprocating upward lifting mechanism, and a resistor placement mechanism. The support testing main body includes a frame, a platform, a resistance tester body, and a back frame. The platform is fixed to the top of the frame, the back frame is located at the back of the frame, and the resistance tester body is mounted on top of the back frame. The lifting mechanism includes a mounting frame and a lifting section. A rotation drive assembly drives a cam to rotate continuously, bringing the alloy resistor into contact with the probe component, which, in conjunction with the resistance tester body, is used to detect the resistance value of the alloy resistor. The continuous and repeated rotation of the rotation drive assembly enables rapid resistance value detection of the alloy resistor. This method is more efficient than the traditional manual method of placing probes or clamps at both ends of the alloy resistor for testing; however, this device still has the following problems. When testing the resistance of alloy resistors, this device can only test each alloy resistor one by one, which is inefficient. Furthermore, during resistance testing, the alloy resistor will experience temperature changes after being powered on, and the resistance will change due to the temperature change. It is difficult to ensure that the measured resistance value is the result after the temperature of the alloy resistor has stabilized by manually controlling the testing time.

[0012] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0013] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0014] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A resistance testing device for alloy resistors, comprising a substrate 1; The substrate 1 is equipped with a carrier plate conveying structure 2 for conveying and clamping the carrier plate 5; The substrate 1 is equipped with an alloy resistor detection and grading mechanism 3 for conveying alloy resistors into the carrier tray 5, detecting the resistance value of the alloy resistors in the carrier tray 5, and grading and unloading them. The alloy resistance detection and grading mechanism 3 includes a detection drive component 31, a detection component 32, and a feeding and grading component 33. The detection drive component 31 is used to drive the detection component 32 to rotate and adjust the distance of the detection component 32 according to the resistance type. The detection component 32 is used to detect the resistance value of the alloy resistance pair. The feeding and grading component 33 is used to grade and feed the alloy resistance according to the resistance value detected by the detection component 32. The substrate 1 and the detection component 32 are both connected to the detection drive component 31. The feeding and grading component 33 is connected to the substrate 1.
[0015] In this invention, after the operator starts the device, the carrier plate conveying structure 2 feeds the alloy resistors into the carrier tray 5, and then drives one carrier tray 5 to move below the detection drive component 31. At this time, the detection drive component 31 adjusts the position of the detection component 32 according to the size of the alloy resistors. Then, the detection component 32 detects the resistance value of the alloy resistors passing through the carrier tray 5 below it. After the detection is completed, the carrier tray 5 moves to the side below the unloading and grading component 33. The unloading and grading component 33 grades and unloads the alloy resistors according to the resistance value detection results of each alloy resistor by the detection component 32. After completion, the carrier plate conveying structure 2 drives the carrier tray 5 with the alloy resistors unloaded to move, and at the same time feeds the carrier tray 5 again to complete the cycle.
[0016] Example 2: In some embodiments, such as Figures 1-5 As shown, in a preferred embodiment of the present invention, the detection drive assembly 31 includes a first servo motor 311, a first splined shaft 312, a second servo motor 313, a first threaded rod 314, and a fixing frame 315; the fixing frame 315 is fixedly connected to the base plate 1; the first splined shaft 312 and the first threaded rod 314 are both rotatably connected to the fixing frame 315; the first servo motor 311 and the second servo motor 313 are both fixedly connected to the fixing frame 315; the driving end of the first servo motor 311 is fixedly connected to the first splined shaft 312; the driving end of the second servo motor 313 is fixedly connected to the first threaded rod 314; the first threaded rod 314 has two symmetrical threaded grooves; the first threaded rod 314 is connected to the detection assembly 32; the first servo motor 311 and the second servo motor 313 are electrically connected to the controller. The detection component 32 includes a first rotating wheel 321, a detection probe 322, and a transverse block 323. Two first rotating wheels 321 are symmetrically distributed left and right. Each first rotating wheel 321 is keyed to a first spline shaft 312. The first rotating wheel 321 slides at its upper limit on the first spline shaft 312 and rotates synchronously with the first spline shaft 312. Multiple detection probes 322 arranged in a circular array are fixedly connected to the outer wall of each first rotating wheel 321. The detection probes 322 on the two first rotating wheels 321 correspond one-to-one. The sides of the two first rotating wheels 321 that are furthest from each other are rotatably connected to the lower end of a transverse block 323. The upper end of the transverse block 323 is threadedly connected to a threaded groove on a first threaded rod 314. The detection probes 322 are electrically connected to the controller via slip rings. The inner ring of the electric slip ring is slidably connected to the first spline shaft 312 via a key block, and the outer ring of the electric slip ring is fixedly connected to the transverse block 323.
[0017] The detection probe 322 adopts existing mature technologies in the field, such as a resistance detection probe disclosed in Chinese patent CN220820116U, which will not be described in detail here.
[0018] The feeding and grading assembly 33 includes a sixth push cylinder 331, a third servo motor 332, a turntable 333, an electric suction cup 334, and a feeding box 336; the lower end of the sixth push cylinder 331 is fixedly connected to the base plate 1; the driving end of the sixth push cylinder 331 is fixedly connected to the third servo motor 332; the driving end of the third servo motor 332 is fixedly connected to the turntable 333; a plurality of electric suction cups 334 arranged in a circular array are fixedly installed on the turntable 333; the plurality of electric suction cups 334 are arranged in a circular array and are fixedly connected to the base plate 1; the third servo motor 332 and the electric suction cups 334 are both electrically connected to the controller.
[0019] In this invention, the operator inputs the dimensions of the alloy resistor inside the carrier disk 5, and the controller starts the second servo motor 313. The second servo motor 313 drives the first threaded rod 314 to rotate. The rotation of the first threaded rod 314 drives two transverse blocks 323 to move synchronously in opposite directions through two symmetrical threaded grooves. The transverse blocks 323 push the turntable 333 to slide along the first spline shaft 312, so that the distance between the corresponding detection probes 322 on the two turntables 333 changes according to the dimensions of the alloy resistor. Then, the first servo motor 311 drives the first spline shaft 312 to rotate. The rotation of the first spline shaft 312 drives the first rotating wheel 321 to rotate. The rotation of the first spline shaft 312 drives the detection probe 322 to rotate. The detection probe 322 rotates until it comes into contact with the alloy resistor inside the carrier disk 5. The movement of the carrier disk 5 and the rotation of the detection probe 322 are synchronized until the detection probe 322 rotates to the rear symmetrical position. During this process, the detection probe 322 continuously detects the resistance value of the alloy resistor to prevent deviation in resistance detection due to short energization time. After detection, the alloy resistor is driven by the carrier disk 5. The device continues to move to the lower end of an electric suction cup 334; the sixth push cylinder 331 drives the third servo motor 332 and the turntable 333 to move down synchronously, and the controller controls the electric suction cup 334 on the upper side of the corresponding alloy resistor to start and adsorb the alloy resistor; after adsorption, the controller controls the sixth push cylinder 331 to reset, and then the third servo motor 332 drives the turntable 333 to rotate. If the alloy resistor is qualified, when the corresponding electric suction cup 334 moves above the carrier belt 4, the sixth push cylinder 331 moves down to drive the electric suction cup 334 to move down. At this time, the controller... The controller controls the electric suction cup 334 on the upper side of the carrier 5 to pick up the next alloy resistor. If the alloy resistor picked up by the electric suction cup 334 on the carrier tape 4 is qualified, the controller controls the electric suction cup 334 to stop picking up the alloy resistor and place the alloy resistor in the contour groove in the carrier tape 4. If the alloy resistor is not qualified, when the corresponding electric suction cup 334 moves to the upper part of the feeding box 336 with the corresponding deviation range, the controller drives the electric suction cup 334 to stop picking up the alloy resistor, so that the alloy resistor falls into the feeding box 336 with the corresponding deviation range.

A clamping plate 222 is fixedly connected; multiple top material blocks 223 are limited and slidably connected to the first conveying plate 214 or the second conveying plate 216; the lower end of the top material block 223 is fixedly connected to the top material plate 224; the driving end of the second push cylinder 225 is fixedly connected to the top material plate 224; the second push cylinder 225 is fixedly connected to the first conveying plate 214 or the second conveying plate 216; the baffle plate 226 is fixedly connected to the upper end of the first conveying plate 214 or the second conveying plate 216. The feeding plate circulation assembly 23 includes a third pusher cylinder 231, a first pusher block 232, a discharge platform 233, a third linear module 234, a fourth pusher cylinder 235, and a second pusher block 236. The third pusher cylinder 231 is fixedly connected to the base plate 1 via a support seat. The driving end of the third pusher cylinder 231 is fixedly connected to the first pusher block 232. The lower end of the discharge platform 233 is fixedly connected to the base plate 1. The third linear module 234 and the second linear module 215 are symmetrically distributed on the left and right sides. The third linear module 234 is fixedly connected to the base plate 1. The fourth pusher cylinder 235 is fixedly connected to the base plate 1 via a support seat. The driving end of the fourth pusher cylinder 235 is fixedly connected to the second pusher block 236. The second feeding plate 216 is fixedly connected to the driving end of the third linear module 234. The alloy resistor feeding assembly 24 includes a feeding frame 241, a baffle block 243, and a fifth pusher cylinder 244; the lower end of the feeding frame 241 is fixedly connected to the substrate 1; a discharge port 242 is opened on the lower left side of the feeding frame 241; the right end of the feeding frame 241 is fixedly connected to the discharge end of an external vibrating feeder; the fifth pusher cylinder 244 is fixedly connected to the feeding frame 241; the driving end of the fifth pusher cylinder 244 is fixedly connected to the baffle block 243; the baffle block 243 slides against the lower side of the feeding frame 241.
[0021] In this invention, after the operator starts the device, the fourth pusher cylinder 235 drives the second pusher block 236 to move. The movement of the second pusher block 236 pushes multiple carrier trays 5 to the left, so that the leftmost carrier tray 5 is aligned with a first conveyor plate 214. Then, the first linear module 212 drives the pusher plate 213 to move. The movement of the pusher plate 213 pushes the leftmost carrier tray 5 to move above the first conveyor plate 214. The rear end of the carrier tray 5 abuts against the baffle plate 226. Then, the first pusher cylinder 221 drives the first clamping plate 222 to clamp the carrier tray 5. After clamping and fixing, the second linear module 215 drives the first feed plate 214 to move past the underside of the detection probe 322. The detection probe 322 detects the alloy resistor in the carrier plate 5. When the alloy resistor in the carrier plate 5 moves to the underside of the electric suction cup 334, the electric suction cup 334 adsorbs the alloy resistor. After the alloy resistor in the carrier plate 5 is completely removed, the second linear module 215 drives the carrier plate 5 to move and align with the unloading table 233. Then, the first push cylinder 221 resets and cancels the clamping of the carrier plate 5. After that, the second push cylinder 225... The top plate 224 pushes the top block 223 upward to push the carrier 5 out of the first conveyor plate 214. After being pushed out, the third push cylinder 231 is activated and pushes the carrier 5 to the upper side of the unloading platform 233 via the first push block 232. At this time, the rightmost carrier 5 on the upper side of the unloading platform 233 enters the upper side of another first conveyor plate 214. The first push cylinder 221 on the other first conveyor plate 214 is activated to clamp the carrier 5. After that, the third linear module 234 can move the other first conveyor plate 214 to the loading rack 24. When the material is below, the fifth push cylinder 244 is activated, causing the baffle block 243 to no longer block the discharge port 242, allowing the alloy resistor to fall through the loading rack 241 into the alloy resistor contour groove opened on the carrier plate 5. After the loading is completed, the fifth push cylinder 244 drives the baffle block 243 to reset. At the same time, the third linear module 234 drives the first conveyor plate 214 to continue moving and align with the feeding table 211. Then, the fourth push cylinder 235 drives the second push block 236 to move. The movement of the second push block 236 pushes multiple carrier plates 5 to move to the left, completing the cycle.
