Description

Technical Field

[0001] The invention relates to the technical field of detection equipment, in particular to an electric heater detection device with classification and screening functions. Background Art

[0002] An electric heater is a device that converts electrical energy into thermal energy and is used to heat air, water or solid objects. They are widely used in home heating, industrial heating, heating water sources, processing and laboratory applications. Electric heaters are usually composed of one or more heating elements (such as resistance wires, electric heating tubes, etc.). Electric current passes through these elements to generate heat, thereby heating the surrounding environment or objects. To detect the quality of a heater, it is necessary to turn on the electric heater and observe the heating effect. A good electric heater should be able to quickly reach the set temperature and maintain a stable temperature so that the heating effect is uniform. Although the existing detection methods are effective, there is a lack of automated detection equipment. Therefore, electric heaters still rely on manual handheld sensors for detection. The high temperature of the detection environment is not only harmful to the health of the operator, but also affects the accuracy of the detection, resulting in some electric heaters with quality problems passing the detection and entering the market. Summary of the invention

Since the diameter of the active bevel gear ring is larger than that of the driven bevel gear, the driven bevel gear drives the active magnetic disk to rotate rapidly. The active magnetic disk can drive the driven magnetic disk to move through magnetic transmission. Since the escapement wheel is restricted by the escapement fork, the detection wheel and the driven magnetic disk are both restricted by the escapement wheel. Therefore, the detection wheel cannot rotate. The active magnetic disk can only provide a rotational circumferential force to the detection wheel through magnetic transmission. Only when the escapement fork releases the restriction on the escapement wheel can the detection wheel rotate, that is, the intermittent rotation of the detection wheel is controlled by the escapement fork.

The power rocker, the slide slot rocker, the main rocker and the auxiliary rocker have the same length, and the length of the auxiliary rocker is twice the length of the main rocker. If the electric heater works normally, the working rocker returns normally. If the electric heater has a defect, the control system will control the electromagnetic clamp to power on during the return of the working rocker, and the flexible clamp block will clamp the end of the electric heater.

Since the diameter of the active bevel gear ring 8 is larger than the diameter of the driven bevel gear 7, the driven bevel gear 7 drives the active magnetic disk 6 to rotate rapidly, and the active magnetic disk 6 can drive the driven magnetic disk 5 to move through magnetic transmission. Since the escapement wheel 9 is restricted by the escapement fork 10, the detection wheel 1 and the driven magnetic disk 5 are both restricted by the escapement wheel 9, so the detection wheel 1 cannot rotate, and the active magnetic disk 6 can only provide a rotational circumferential force to the detection wheel 1 through magnetic transmission. Only when the escapement fork 10 releases the restriction on the escapement wheel 9 can the detection wheel 1 rotate, that is, the intermittent rotation of the detection wheel 1 is controlled by the escapement fork 10.

[0028] An escape wheel 9 is also provided on the side of the detection wheel 1 connected to the driven magnetic disk 5. An escapement fork 10 is rotatably provided on the front column 3. The escapement fork 10 cooperates with the escapement wheel 9. A rope 11 is connected to the rotating shaft of the escapement fork 10. The rope 11 is located between the front column 3 and the rear column 4. One end of the rope 11 is connected to a spring 12, and the other end of the rope 11 is connected to an iron block 13. There is a positioning slide on the equipment bracket, and the iron block 13 is slidably installed in the positioning slide. An electromagnet 14 is provided at the bottom of the positioning slide. The electromagnet 14 is connected to a control system through a circuit. Every time the control system controls the electromagnet 14 to be energized once, the electromagnet 14 attracts the iron block 13, and the iron block 13 pulls the escapement fork 10 to rotate through the rope 11.

The rotation angle of the detection wheel 1 is the angle between two adjacent electric heaters on the detection wheel 1.

[0029] A cover 15 is provided on the equipment bracket, and the detection rod group includes an auxiliary rocker arm 16, a working rocker arm, a driving rocker arm and a crank plate 21. The auxiliary rocker arm 16 is rotatably mounted on the cover 15, the working rocker arm is composed of a main rocker arm 171 and a secondary rocker arm 172, the main rocker arm 171 and the secondary rocker arm 172 are installed in a straight line, the driving rocker arm is composed of a power rocker arm 201 and a chute rocker arm 202, the power rocker arm 201 and the chute rocker arm 202 are connected in an L shape, and the connection between the power rocker arm 201 and the chute rocker arm 202 is rotatably connected to the equipment bracket, the crank plate 21 is rotatably mounted on the equipment bracket, and the crank A driven sprocket 28 is coaxially connected to one side of the disk 21, an adjusting slider 23 is slidably arranged in the crank disk 21, an adjusting bolt 22 is rotatably installed on the crank disk 21, the adjusting bolt 22 is threadedly connected to the adjusting slider 23, the auxiliary rocker arm 16 is rotatably connected to one end of the main rocker arm 171, one end of the main rocker arm 171 is rotatably connected to the power rocker arm 201, a through groove is provided on the slide rocker arm 202, the adjusting slider 23 is slidably connected to the through groove, a contact switch (not shown in the figure) is provided at the rotation installation position of the auxiliary rocker arm 16 and the cover shell 15, and the contact switch is connected to the control system circuit.

[0030] The active chain 26 drives the linkage sprocket 27 to rotate, and the linkage sprocket 27 drives the driven sprocket 28 connected to the crank disk 21 to rotate through the driven chain 29. When the crank disk 21 rotates, it drives the adjusting slider 23 to rotate, and the adjusting slider 23 drives the slide groove rocker 202 to swing, and the driving rocker drives the working rocker to swing, and the working rocker further drives the electromagnetic clamp 18 to move repeatedly. The operator changes the distance from the adjusting slider 23 to the rotation center of the crank disk 21 by rotating the adjusting bolt 22, thereby changing the swing amplitude of the driving rocker, and further changing the rotation amplitude of the working rocker. Through the setting of the detection rod group, the motion trajectory of the electromagnetic clamp 18 at the end of the auxiliary rocker 172 approaches a straight line within a range, and the temperature sensor on the electromagnetic clamp 18 scans and detects the surface of the electric heater, and determines whether the heater is working normally by detecting the temperature of the surface of the electric heater.

[0031] An electromagnetic clamp 18 is provided at one end of the auxiliary rocker 172 away from the main rocker 171, and a flexible clamping block 19 is provided on the electromagnetic clamp 18. A temperature sensor is installed on the electromagnetic clamp 18, and the electromagnetic clamp 18 is connected to the control system circuit. The power rocker 201, the slide slot rocker 202, the main rocker 171 and the auxiliary rocker 172 have the same length. The length of the auxiliary rocker 16 is twice the length of the main rocker 171. The power component includes a servo motor 24, a driving sprocket 25 and two interlocking sprockets 27. The two interlocking sprockets 27 are respectively located directly below the two driven sprockets 28. Each interlocking sprocket 27 is composed of two sprockets. A driven chain 29 is connected between the interlocking sprocket 27 and the driven sprocket 28. The driving sprocket 25 is installed on the servo motor 24. The driving sprocket 25 and the two interlocking sprockets 27 are connected with the same driving chain 26. If the electric heater works normally, the working rocker returns normally. If the electric heater is defective, the control system will control the electromagnetic clamp 18 to be energized during the return of the working remote rod, and the flexible clamp 19 will clamp the end of the electric heater. During the swing back process, the electric heater will be unplugged from the plug-in hole of the detection wheel 1, and the defective electric heater will be put into the collection frame (not shown in the figure). The auxiliary swing rod 16 touches the contact switch when the working remote rod swings back to the end. The contact switch controls the electromagnet 14 to be energized, that is, the working rocker drives the electromagnetic clamp 18 to scan and detect the electric heater once, the detection wheel 1 rotates once, and an electric heater is replaced for the next round of detection. The unloading robot will unplug the electric heater left on the plug-in hole of the detection wheel 1 and place it on the conveyor line for subsequent manufacturing processes. The detection wheel 1 is driven by the power component to cooperate with the detection rod group to realize the detection and screening of the electric heater, thereby improving the detection efficiency and detection accuracy of the electric heater.

[0032] The working principle of the present invention is as follows: after the feeding robot inserts the electric heater to be detected into the plug hole, the electric heating is connected to the contact circuit, and the electric heater starts to heat up. After a period of heating, the electric heater moves to the bottom along with the detection wheel 1, and the detection rod group detects the electric heater through the temperature sensor. After the servo motor 24 is energized, it drives the active sprocket 25 to rotate, and the active sprocket 25 drives the linkage sprocket 27 to rotate through the active chain 26. The linkage sprocket 27 drives the driven sprocket 28 connected to the active bevel gear ring 8 to rotate through the driven chain 29. The driven sprocket 28 drives the active bevel gear ring 8 to rotate, and the active bevel gear ring 8 rotates. The ring 8 drives the driven bevel gear 7 to rotate. Since the diameter of the active bevel gear ring 8 is larger than that of the driven bevel gear 7, the driven bevel gear 7 drives the active magnetic disk 6 to rotate quickly. The active magnetic disk 6 can drive the driven magnetic disk 5 to move through magnetic transmission. Since the escapement wheel 9 is restricted by the escapement fork 10, the detection wheel 1 and the driven magnetic disk 5 are both restricted by the escapement wheel 9. Therefore, the detection wheel 1 cannot rotate. The active magnetic disk 6 can only provide a rotational circumferential force to the detection wheel 1 through magnetic transmission. Only when the escapement fork 10 releases the restriction on the escapement wheel 9 can the detection wheel 1 rotate, that is, the intermittent rotation of the detection wheel 1 is controlled by the escapement fork 10.

[0033] Every time the control system controls the electromagnet 14 to be energized once, the electromagnet 14 attracts the iron block 13, and the iron block 13 pulls the escapement fork 10 to rotate through the rope 11. After the electromagnet 14 is energized, the spring 12 pulls the escapement fork 10 to reset through the rope 11, that is, the escapement fork 10 swings back and forth once, and the detection wheel 1 rotates once. The rotation angle of the detection wheel 1 is the angle between the two adjacent electric heaters on the detection wheel 1. The active chain 26 drives the linkage sprocket 27 to rotate, and the linkage sprocket 27 drives the driven sprocket 28 connected to the crank disk 21 to rotate through the driven chain 29. When the crank disk 21 rotates, it drives the adjusting slider 23 to rotate, and the adjusting slider 23 drives the slide groove rocker 202 to swing, and the driving rocker drives the working rocker to swing, and the working rocker further drives the electromagnetic clamp 18 to move repeatedly.

[0034] The operator changes the distance from the adjusting slider 23 to the rotation center of the crank disk 21 by turning the adjusting bolt 22, thereby changing the swing amplitude of the driving rocker arm and further changing the rotation amplitude of the working rocker arm. By setting the detection rod group, the motion trajectory of the electromagnetic clamp 18 at the end of the auxiliary rocker arm 172 approaches a straight line within a certain range. The temperature sensor on the electromagnetic clamp 18 scans and detects the surface of the electric heater. By detecting the temperature of the surface of the electric heater, it is determined whether the heater is working normally. If the electric heater is working normally, the working rocker arm returns normally. If the electric heater has a defect, the control system will control the electromagnetic clamp 18 to be energized during the return of the working rocker arm, and the flexible clamp 19 clamps the electric heater. At the end of the test wheel 1, the electric heater is unplugged from the socket of the detection wheel 1 during the swing back process, and the defective electric heater is put into the collection frame. The auxiliary swing arm 16 touches the contact switch when the working remote rod swings back to the end. The contact switch controls the electromagnet 14 to be energized, that is, the working rocker drives the electromagnetic clamp 18 to scan and detect the electric heater once, the detection wheel 1 rotates once, and an electric heater is replaced for the next round of detection. The unloading robot unplugs the electric heater left on the socket of the detection wheel 1, and places it on the conveyor line body for subsequent manufacturing processes. The detection wheel 1 is driven by the power component to cooperate with the detection rod group to realize the detection and screening of the electric heater, thereby improving the detection efficiency and detection accuracy of the electric heater.
