Description

Technical Field

[0001] The present application relates to the field of batch detection of sensors, and in particular to a glass-sealed resistor sorting device. Background Art

[0002] Glass-sealed resistors, especially glass-sealed thermistors, are electronic components that measure electrical properties based on the material's resistance changing with temperature. This type of resistor exploits the fact that the number of carriers in semiconductor materials changes with temperature, creating a relationship between their resistance and temperature. As the temperature rises, the resistance of glass-sealed thermistors with a negative temperature coefficient (NTC) decreases, while the resistance of glass-sealed thermistors with a positive temperature coefficient (PTC) increases. In the home appliance sector, glass-sealed resistors are used for functions such as temperature control and overheating protection to ensure the safe operation of home appliances. In the automotive sector, with the rapid development of new energy vehicles and intelligent driving technologies, glass-sealed resistors play an important role in battery management systems and engine control. In the industrial control sector, glass-sealed resistors, with their high precision and fast response, provide strong support for temperature monitoring and fault warning of industrial equipment.

[0003] The resistance testing of glass-sealed resistors currently relies mainly on manual operation. This traditional method is not only inefficient, but also difficult to effectively control the testing environment temperature due to its exposed design. Since the testing temperature cannot be precisely defined, the quality of the test results is uneven, making it difficult to meet the strict requirements of subsequent precision sorting work. Summary of the Invention

[0004] This device provides a glass-sealed resistor sorting device, and the specific implementation is as follows:

[0005] A glass-sealed resistor sorting device, comprising:

[0006] The box body and the feed turntable and feeding turntable inside the box body are provided with a transfer assembly for conveying glass-sealed resistors. The side of the feed turntable is provided with a feeder, a first flush assembly and a branching assembly in sequence along its circumference. The side of the feed turntable is provided with a magnetic block for adsorbing the glass-sealed resistors introduced from the feeder. The first flush assembly and the branching assembly are used to sort the glass-sealed resistors on the feeder.

[0007] The side of the feeding turntable is provided with a detection component and several grabbing machines along its circumference. The detection component is connected to the multimeter. The side of the feeding turntable is provided with several positioning seats for magnetically attracting glass-sealed resistors along its circumference. The cross-section of the positioning seat is a C-shaped seat body, and its upper and lower ends are provided with sawtooth grooves. The middle part of the C-shaped seat body is used to magnetically attract the head of the glass-sealed resistor, and its head is also in contact with the detection probe of the detection component to realize resistance detection. The first sampling claw of each grabbing machine flips through the sawtooth groove and acts on the glass-sealed resistor to realize classified grabbing according to the resistance value.

[0008] Based on the above technical solution, the feed turntable and the delivery turntable enable efficient batch transportation of glass-sealed resistors, significantly improving the efficiency of the sorting operation. At the same time, through the coordinated action of the first flush assembly, the second flush assembly, and the branching assembly, we have carried out batch arrangement of the glass-sealed resistors during the transportation process, making preliminary preparations for subsequent inspection work.

[0009] Preferably, the upper and lower parts of the box body are divided into an installation chamber and a temperature control chamber, both of which are provided with openings at the position of the detection component, the feeding turntable and the feed turntable are rotated in the installation chamber, and the detection component is arranged in the temperature control chamber.

[0010] Preferably, the feeding turntable is provided with several vertical slide rails slidably connected to the positioning seat along the circumference, and a guide ring in the shape of an oblique closed loop is provided on the outer side thereof; a second roller abutting against the guide ring is provided at the end of the positioning seat, and the lower end of the guide ring vertically corresponds to the detection component in the opening.

[0011] Based on the above technical solution, by configuring an independent temperature-controlled chamber and combining it with a guide ring with an oblique closed-loop design, the transportation height of the glass-sealed resistor can be adjusted. This ensures that the resistor can be kept in a specific temperature environment during the resistance value detection process, thereby achieving precise control of the detection temperature and further enhancing the accuracy and reliability of the test results.

[0012] Preferably, the feeder includes a translation drive box and a suction tube that is lifted and lowered on the side of the translation drive box, and the output end of the translation drive box is connected to the second drive motor; the suction tube sucks the glass-sealed resistor downward, and the output end of the second drive motor is provided with a second sampling claw that acts on the end of the suction tube, and the second sampling claw flips in the opposite direction to transfer the glass-sealed resistor upside down to the magnetic suction block.

[0013] Based on the above technical solution, a feeder is configured to enable the glass-sealed resistor to be quickly and magnetically assembled on the feed turntable in an inverted manner; in addition, the suction tube is raised and lowered by a cylinder structure, and a columnar protrusion is designed on the second sampling claw, which can abut against the air path of the suction tube to effectively release its suction function.

[0014] Preferably, the first leveling component includes a vertical push plate and a flat push plate that abuts the head of the glass-sealed resistor. The front end of the vertical push plate is configured as a V-shaped head that acts on the wiring harness of the glass-sealed resistor, and the flat push plate and the vertical push plate are connected to the same pneumatic source.

[0015] Preferably, the branching assembly includes a first base connected to the forward propulsion part, a translation block is longitudinally provided on the first base, and a wedge-shaped guide block connected to the driving member is transversely provided; the inclined surfaces on both sides of the wedge-shaped guide block abut against the first roller on the translation block, and the two translation blocks are respectively provided with a toggle pin that acts on the glass-sealed resistor harness to cause it to fork.

[0016] Based on the above technical solution, vertical and horizontal push plates are used to position the bottom surface of the glass-sealed resistor head and stabilize it laterally on the magnetic block. The outward bifurcation of the glass-sealed resistor harness is achieved through the reverse coordinated action of the two toggle pins in the branching assembly. In addition, a spring return mechanism is connected between the two translation blocks to ensure flexibility and reset accuracy, while the forward propulsion unit adopts a cylinder-like structure to achieve efficient and stable propulsion operation.

[0017] Preferably, the transfer assembly is provided with a pneumatic push plate through a suspension, and the magnetic block corresponds horizontally to the C-shaped seat body, and the front end of the pneumatic push plate is set to be V-shaped.

[0018] Preferably, it also includes a second leveling component arranged on the side of the feeding turntable, and the second leveling component is arranged between the grabber and the transfer component, and the second leveling component has a built-in lifting module, and a positioning pin is provided at the output end thereof, and the positioning pin acts on the head of the glass-sealed resistor from top to bottom.

[0019] Based on the above technical solution, a pneumatic push plate is used to cancel the magnetic adsorption of the magnetic block on the head of the glass-sealed resistor. Then the entire head of the glass-sealed resistor can be smoothly magnetically inserted into the inner side of the C-shaped base, thereby achieving limited fixation; in this process, the wiring harness part of the glass-sealed resistor will pass upward through the serrated groove and be exposed. The lifting module is designed as a cylinder-like structure, which drives the positioning pin to move vertically and acts on the head of the glass-sealed resistor to ensure the vertical positioning of the glass-sealed resistor on the bottom of the C-shaped base.

[0020] Preferably, the gripping machine further comprises a base, a side portion of which acts on the first sampling claw via the first drive motor, and a front end of the first sampling claw is configured as a U-shaped structure capable of passing through the serrated groove.

[0022] 1. This utility model realizes batch conveying of glass-sealed resistors through the feed turntable and the delivery turntable, greatly improving the sorting efficiency.

The end of the positioning seat 13 is provided with a second roller 1301 abutting against the guide ring 12, and the lower end of the guide ring 12 is vertically corresponding to the detection component 14 in the opening.
