Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a fuse sand filling detection device. Background Art

[0002] A fuse, also known as a fuse link, refers to an electrical component that melts its fuse element by the heat generated by itself to cut off the circuit when the current exceeds the specified value. Fuse links are widely used in high and low voltage power distribution systems, control systems, and electrical equipment. As a short circuit and overcurrent protector, it is one of the most commonly used protection devices.

[0003] The fuse sand filling technology is an important process for fuse manufacturing. The sand filling process usually includes pouring the filling material into the fuse housing, then pressurizing to expel air bubbles, and then curing at appropriate temperature and humidity. Inside the fuse, the sand filling can play the following roles:

[0004] 1. Protect electronic components. There are usually electronic components inside the fuse, such as copper wires or silver, used to connect the circuit. The sand filling can fix the electronic components in their proper positions and protect them from environmental influences (such as moisture, vibration, etc.).

[0005] 2. Strengthen the mechanical strength of the fuse. The fuse housing is usually made of plastic or ceramic and is easily damaged. The sand filling can fill the air voids, increasing the mechanical strength and impact resistance of the housing.

[0006] 3. Prevent foreign substances from entering the interior. Inside the fuse, the sand filling can fill the air voids to prevent moisture, dust, chemical substances, etc. from entering, preventing damage to electronic components and affecting the operation of the circuit.

[0007] In the prior art, sand filling is carried out by a sand filling device. However, there are the following defects in the existing sand filling process: First, the existing sand filling device stores quartz sand in a sand storage tank, and a pipeline is arranged at the bottom of the sand storage tank to guide the quartz sand to the sand filling hole for sand filling. However, since quartz sand is easy to absorb water vapor in the air, its fluidity becomes poor, making it difficult to ensure the ramming density of quartz sand in the fuse. Second, the quartz sand enters the sand filling hole by gravity, and the quartz sand in the fuse is relatively loose and not tight enough, making it difficult to ensure the safety characteristics of the fuse. Therefore, a device is needed to detect the fuse products after sand filling to ensure the product qualification rate. Summary of the Utility Model

[0008] The utility model aims at the defects existing in the prior art and provides a fuse sand filling detection device.

[0009] In order to solve the above technical problems, the utility model is solved by the following technical solutions.

[0010] A fuse sand filling detection device comprises a rotating mechanism and a detection mechanism. The rotating mechanism is used to receive and fix the fuse product and transport it to a target working position. The rotating mechanism comprises a turntable and a driving motor. The turntable is provided with a plurality of circumferentially distributed limit grooves. The driving motor is used to drive the turntable to rotate periodically. The detection mechanism is arranged above the rotating mechanism, and comprises a detection cylinder, a pressure sensor and a detection rod. The output end of the detection cylinder is fixedly connected to the pressure sensor and the detection rod connected to the lower end of the pressure sensor. The detection cylinder drives the detection rod to penetrate the fuse product and resist the sand material to perform detection work.

[0011] Preferably, limit plates are provided on both sides of the limit slot, and the limit plates include fixed limit plates and movable limit plates. The fixed limit plates are provided on the side of the limit slot close to the center of the turntable, and the movable limit plates are provided on the side of the limit slot away from the center of the turntable.

[0012] Preferably, a pushing mechanism is provided on the inner side of the turntable, and the pushing mechanism includes an operating table, a pushing rod and a PLC controller. The PLC controller is used to control the telescopic movement of the pushing rod after receiving a signal from a pressure sensor.

The first push rod is used to push out qualified products, and the second push rod is used to push out unqualified products.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0025] As Figures 1 to 4 shown, it shows a fuse sand filling detection device provided by an embodiment of the present application, including a rotating mechanism and a detection mechanism. The rotating mechanism is used to receive a fixed fuse product and transport it to a target working position. The rotating mechanism includes a turntable 1, a limit plate, and a driving motor 13. There are a plurality of uniformly distributed limit grooves 14 on the turntable 1. In this embodiment, four limit grooves 14 are adopted. Limit plates are provided on both sides of the limit groove 14. The limit plates include a fixed limit plate 11 and a movable limit plate 12. The fixed limit plate 11 is arranged on the side of the limit groove 14 close to the center of the turntable 1. An arc-shaped groove 111 is provided on the fixed limit plate 11 for limiting the fuse product. The movable limit plate 12 is arranged on the side of the limit groove 14 away from the center of the turntable 1. The driving motor 13 is used to drive the turntable 1 to rotate periodically; the detection mechanism is arranged above the rotating mechanism and includes a detection cylinder 21, a pressure sensor 22, and a detection rod 23. The output end of the detection cylinder 21 is fixedly connected to the pressure sensor 22 and the detection rod 23 connected to the lower end of the pressure sensor 22. The detection cylinder 21 performs detection work by driving the detection rod 23 to penetrate and abut against the fuse product sand.

[0026] Inside the turntable 1, there is a material pushing mechanism, which includes an operating table 31, a material pushing rod, and a PLC controller. The PLC controller is used to control the telescopic movement of the material pushing rod after receiving the signal from the pressure sensor 22. If the detection result is qualified, it will be pushed out after rotating one station; if the detection result is unqualified, it will be pushed out after rotating two stations.

[0027] The material pushing rod includes a first material pushing rod 32 and a second material pushing rod 33. The first material pushing rod 32 and the second material pushing rod 33 are respectively arranged on the operating table 31 and move through the limiting slots 14 respectively. The first material pushing rod 32 is used to push out qualified products, and the second material pushing rod 32 is used to push out unqualified products, which are respectively carried out in the limiting slots 14 of the third station and the fourth station.

[0028] The movable limiting plate 12 is connected with a rotating shaft 121, the rotating shaft 121 is connected with a control motor 122, and the control motor 122 is connected with the PLC controller, so as to cooperate to open and close the movable limiting plate 12 in different stations.

[0029] Outside the turntable 1, there is a material receiving mechanism 4, which is used to receive the detected fuse products and convey them. The material receiving mechanism 4 includes a driving roller 41 and a conveyor belt 42. The driving roller 41 drives the conveyor belt 42 to rotate, which is convenient for subsequent process treatment.

[0030] During the use process, the fuse products can be placed into the limiting slots 14 of the turntable 1 manually or through the corresponding conveying mechanism. At this time, the movable limiting plate 12 is in the open state. The arc shape of the fixed limiting plate 11 in the limiting slot 14 can fix the fuse products well in the corresponding detection positions. After placing, the movable limiting plate 12 is closed and rotates clockwise into the next station for detection. The detection mechanism drives the detection rod 23 to penetrate into the sand filling hole on the fuse product through the detection cylinder 21, so as to resist against the internal sand material for detection work. The pressure sensor 22 thus measures the pressure information, and transmits the downward distance of the detection rod 23 and the feedback pressure signal to the PLC controller, so as to judge whether the sand amount in the fuse product is qualified, and transport the qualified products to the next station, open the movable limiting plate 12 at this station, and cooperate with the first material pushing rod 32 to push out. The unqualified products are continuously transported to the next station, open the movable limiting plate 12 at this station, and cooperate with the second material pushing rod 33 to push out.

[0031] Through the mutual cooperation of the turntable 1 and the limiting plate, the utility model places the fuse products to be detected into the limiting slots 14 and transports them to the detection position, improving the stability of the transportation and subsequent detection processes; through the setting of the detection mechanism, it can quickly judge whether the fuse products to be detected are qualified in sand filling, improving the detection efficiency; through the material pushing mechanism, the judged fuse products can be pushed out respectively as qualified products and unqualified products, having the function of pre-classification and improving the processing efficiency of subsequent processes.
