Description

Technical Field

[0001] This utility model relates to the field of overheat protector testing, specifically an overheat protector current detection device with a feeding function. Background Technology

[0002] An overheat protector is a device used to monitor the temperature of equipment or system and automatically cut off the power supply or trigger a protection mechanism when the temperature exceeds a safe threshold to prevent damage or safety accidents caused by overheating. After production, overheat protectors need to undergo current testing to ensure safety during use and thus ensure product quality. Currently, when performing current testing on larger overheat protectors, they are usually transported by conveyor belt.

[0003] Currently, when transporting overheat protectors via conveyor belt, the conveyor belt stops running when the overheat protector is transported to the bottom of the testing equipment. However, the heavier overheat protector will move forward a short distance due to inertia, requiring operators to manually adjust its position, thus reducing the testing efficiency. Therefore, to address the above problem, an overheat protector current detection device with a feeding function is proposed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and avoid the problem of overheat protectors requiring manual adjustment due to positional deviations, which reduces the detection efficiency of overheat protectors, this utility model proposes an overheat protector current detection device with a feeding function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an overheat protector current detection device with feeding function, comprising:

[0006] Mounting frame, the mounting frame having a conveying assembly inside;

[0007] A stop-stop component, the stop-stop component being disposed on the surface of the mounting bracket;

[0008] An antistatic assembly is disposed on the left side of the top of the mounting bracket;

[0009] The interception assembly includes a fixed frame 1 fixedly installed at the top center of the mounting bracket. A Hall sensor and a photoelectric sensor are fixedly installed on the top wall of the fixed frame 1. A groove is formed at the bottom right end of the fixed frame 1. A motor is fixedly installed inside the bottom end of the groove. A rotating rod is fixedly connected to the output shaft at the top of the motor. A baffle is fixedly connected to the surface of the rotating rod. A magnet is fixedly installed inside the baffle at the end away from the rotating rod. A torsion spring is fixedly connected to the top end of the baffle. A support platform is fixedly installed inside the mounting bracket. An electromagnet is fixedly installed inside the support platform.

[0010] Preferably, the photoelectric sensor is electrically connected to the microprocessor, motor, and electromagnet. When the photoelectric sensor detects that the overheat protector below has moved to the processing area, the motor is driven to rotate the baffle, thereby intercepting the overheat protector and keeping it in the processing area for detection.

[0011] Preferably, the baffle has two ends that are adapted to and attached to each other, and the near ends of the two magnets are opposite magnetic poles. The two baffles are stably attached together by the magnets, so that the two baffles can intercept the overheat protector.

[0012] Preferably, the torsion spring is wound around the surface of the rotating rod, and the top end of the torsion spring is fixedly connected to the top wall of the groove. The rebound force of the torsion spring can cause the baffle to rotate away from the conveyor belt, so that the baffle will not block the feeding of the overheat protector.

[0013] Preferably, the conveying assembly includes two drive rods rotatably connected to the left and right sides inside the mounting frame. A conveyor belt is sleeved on the surface of the two drive rods, and a belt is sleeved on the surface of the drive rods. A rotating rod is sleeved on the side of the belt away from the drive rods. A brush is fixedly connected to the surface of the rotating rod. A guide rail is fixedly connected to the inner wall of the mounting frame. Slider blocks are slidably connected to the left and right sides inside the guide rail. A pressure rod is fixedly connected to the end of the slider away from the inner wall of the mounting frame, and a pressure spring is fixedly connected to the surface of the slider.

[0014] Preferably, the front and rear ends of the rotating rod are rotatably connected to the front and rear sides inside the mounting frame, and the brush is adapted to fit the bottom of the conveyor belt, so that the brush can clean the bottom of the conveyor belt.

[0015] Preferably, the two pressure rods are respectively fitted to the left and right sides of the belt, and the end of the pressure spring away from the slider is fixedly installed on the inner wall of the guide rail. The bottom ends of the Hall sensor and the photoelectric sensor are facing the top surface of the conveyor belt. The two pressure rods approach each other under the action of the pressure spring force. At this time, the two pressure rods can tighten the belt, so that the belt can stably drive the rotating rod to rotate.

[0016] Preferably, the static eliminator includes a fixed frame two that is fixedly installed on the top left side of the mounting frame. An ion air bar is fixedly installed on the top wall of the fixed frame two. The ion air bar can eliminate static electricity at the feeding point of the moving conveyor belt below, preventing static electricity from attracting dust.

[0017] The advantages of this utility model are:

[0018] When the overheat protector is transported via a conveyor belt, the baffle automatically intercepts it, placing it within the detection area. Furthermore, the energized electromagnet below the conveyor belt attracts the overheat protector transported above, further defining its position for subsequent direct current detection. Additionally, a brush removes dust from the bottom of the conveyor belt, and an ionizer removes static electricity from the loading area, preventing the conveyor belt surface from accumulating excessive dust. This prevents the overheat protector's metal contacts from attracting dust or oil, which could lead to poor contact and increased resistance, thus ensuring the accuracy of current detection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The following is in conjunction with the appendix Figure 1 — Figure 5 This application will be described in further detail.

[0028] This application discloses an overheat protector current detection device with a feeding function. (Refer to...) Figure 1 A current detection device for an overheat protector with a feeding function, comprising:

[0029] Mounting frame 1, with a conveying component 2 installed inside the mounting frame 1;

[0030] Stop component 3 is disposed on the surface of mounting bracket 1;

[0031] The static eliminator 4 is located on the left side of the top of the mounting bracket 1;

[0032] Reference Figure 2 and Figure 5The stopping component 3 includes a fixed frame 311 fixedly installed at the top center of the mounting bracket 1. A Hall sensor 312 and a photoelectric sensor 32 are fixedly installed on the top wall of the fixed frame 311. A groove 331 is formed at the bottom right end of the fixed frame 311. A motor 332 is fixedly installed inside the bottom end of the groove 331. A rotating rod 333 is fixedly connected to the output shaft at the top of the motor 332. A baffle 334 is fixedly connected to the surface of the rotating rod 333. A magnet 335 is fixedly installed inside the end of the baffle 334 away from the rotating rod 333. Two baffles 334 have two ends that are far from the fixed frame 311 and are fitted together. The near ends of the two magnets 335 are opposite magnetic poles. The two baffles 334 are stably attached together by the magnets 335, so that the two baffles 334 can intercept the overheat protector. A torsion spring 336 is fixedly connected to the top of the baffle 334. The torsion spring 336 is wound around the surface of the rotating rod 333. The top of the torsion spring 336 is fixedly connected to the top wall of the groove 331. The rebound force of the torsion spring 336 rotates the baffle 334 away from the conveyor belt 22. At this time, the baffle 334 will not block the feeding of the overheat protector.

[0033] The mounting bracket 1 has a support platform 341 fixedly installed inside, and an electromagnet 342 is fixedly installed inside the support platform 341. The photoelectric sensor 32 is electrically connected to the microprocessor, motor 332, and electromagnet 342. When the photoelectric sensor 32 detects that the overheat protector below has moved to the processing area, the motor 332 is driven to rotate the baffle 334, thereby intercepting the overheat protector and keeping it in the processing area for detection.

[0034] Reference Figure 2 - Figure 4The conveying assembly 2 includes two drive rods 21 rotatably connected to the left and right sides inside the mounting frame 1. A conveyor belt 22 is sleeved on the surface of the two drive rods 21, and a belt 23 is sleeved on the surface of the drive rods 21. A rotating rod 24 is sleeved on the side of the belt 23 away from the drive rods 21. A brush 25 is fixedly connected to the surface of the rotating rod 24. The front and rear ends of the rotating rod 24 are rotatably connected to the front and rear sides inside the mounting frame 1, respectively. The brush 25 is adapted to fit and fit against the bottom of the conveyor belt 22, and the brush 25 can clean the bottom of the conveyor belt 22. A guide rail 261 is fixedly connected to the inner wall of the mounting frame 1, and the left and right sides inside the guide rail 261 are slidably connected. There is a slider 262, and a pressure rod 263 is fixedly connected to the end of the slider 262 away from the inner wall of the mounting bracket 1. A pressure spring 264 is fixedly connected to the surface of the slider 262. The two pressure rods 263 are respectively adapted to fit against the left and right sides of the belt 23. The end of the pressure spring 264 away from the slider 262 is fixedly installed on the inner wall of the guide rail 261. The bottom ends of the Hall sensor 312 and the photoelectric sensor 32 are facing the top surface of the conveyor belt 22. The two pressure rods 263 approach each other under the action of the elastic force of the pressure spring 264. At this time, the two pressure rods 263 can tighten the belt 23, so that the belt 23 can stably drive the rotating rod 24 to rotate.

[0035] Reference Figure 2 The static eliminator 4 includes a fixed frame 2 41 fixedly installed on the top left side of the mounting frame 1. An ion air bar 42 is fixedly installed on the top wall of the fixed frame 2 41. The ion air bar 42 can eliminate static electricity at the feeding point of the moving conveyor belt 22 below, preventing static electricity from attracting dust.

[0036] Working principle: The operator places the overheat protector with detection on the upper left side of the top of the conveyor belt 22 in the loading area. At this time, the drive rod 21 drives the conveyor belt 22 to transport the overheat protector. When the overheat protector moves to the right and is below the photoelectric sensor 32, the photoelectric sensor 32 receives a signal and drives the motor 332 and the electromagnet 342 through the microprocessor. After the motor 332 starts, it drives the baffle 334 to rotate. At this time, the two baffles 334 rotate against the elastic force of the torsion spring 336 until the two baffles 334 rotate to their near ends and stick together. At this time, the magnets 335 inside the two baffles 334 attract each other. At this time, the two baffles 334 can intercept the moving overheat protector. At the same time, the electromagnet 342 is energized and attracts the overheat protector transported above, further limiting the overheat protector, so that the overheat protector stops below the Hall sensor 312. Then, the current signal can be collected by the Hall sensor 312 to detect the current.

[0037] When the drive rod 21 rotates, it drives the rotating rod 24 to rotate via the belt 23. At this time, the rotating rod 24 drives the brush 25 to rotate, and the brush 25 can clean the bottom of the conveyor belt 22. Meanwhile, the slider 262, under the action of the pressure spring 264, drives the pressure rod 263 to press tightly against the belt 23, so that the two pressure rods 263 keep the belt 23 taut. This allows the belt 23 to drive the rotating rod 24 to rotate stably, ensuring that the brush 25 cleans the conveyor belt 22. At the same time, the operator can activate the ion air bar 42 to remove static electricity from the feeding area on the left side of the top of the conveyor belt 22, preventing the static electricity on the surface of the conveyor belt 22 from attracting dust and contaminating the stored electricity of the overheat protector, thus avoiding affecting the current detection effect of the overheat protector.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
