Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and particularly to an electric heater detection device with a classification and screening function. Background Art

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

[0003] The purpose of the present invention is to provide an electric heater detection device with a classification and screening function to solve the problems raised in the above background art.

[0004] To solve the above technical problems, the present invention provides the following technical solution: An electric heater detection device with a classification and screening function includes an equipment support, a loading robot, an unloading robot, and several electric heaters to be detected. A detection runner, a power assembly, and a detection rod group are installed on the equipment support. Plug holes are evenly distributed in a ring on the detection runner, and a contact circuit is arranged inside the detection runner. The loading robot inserts the electric heater into the plug hole, and the unloading robot removes the detected electric heater. The power assembly drives the detection runner to rotate intermittently. A temperature sensor is installed on the detection rod group, and the temperature sensor detects the electric heater. After the loading robot inserts the electric heater to be detected into the plug hole, the electric heater is connected and conducted with the contact circuit, and the electric heater starts to heat. After a period of heating, the electric heater moves to the bottom along with the detection runner, and the detection rod group detects the electric heater through the temperature sensor.

[0005] Further, a front column and a rear column are provided on the device bracket. A support shaft is provided above the front column and the rear column. The detection runner is rotatably installed on the support shaft. A driven disk is installed at one end of the detection runner away from the insertion hole. A driving disk is sleeved and installed on the support shaft. A plurality of pairs of magnets are evenly arranged in a ring on the side of the driven disk close to the driving disk. The magnetic poles of two adjacent magnets facing the outside are opposite. The structure of the driving disk is the same as that of the driven disk.

[0006] Further, a driven bevel gear is coaxially connected to the side of the driving disk away from the driven disk. The power assembly includes a driving bevel gear ring and a driven sprocket. The driving bevel gear ring is installed on the device bracket. The driving bevel gear ring meshes with the driven bevel gear for transmission. The side of the driving bevel gear ring away from the rear column is coaxially connected to the driven sprocket. After the servo motor is powered on, it drives the driving sprocket to rotate. The driving sprocket drives the linkage sprocket to rotate through the driving chain. The linkage sprocket drives the driven sprocket connected to the driving bevel gear ring to rotate through the driven chain. The driven sprocket drives the driving bevel gear ring to rotate. The driving bevel gear ring drives the driven bevel gear to rotate. Since the diameter of the driving bevel gear ring is larger than that of the driven bevel gear, the driven bevel gear drives the driving disk to rotate rapidly. The driving disk can drive the driven disk to move through magnetic force transmission. Since the escapement wheel is restricted by the escapement fork and the detection runner and the driven disk are both restricted by the escapement wheel, the detection runner cannot rotate. The driving disk can only provide a circumferential force for the detection runner to rotate through magnetic force transmission. Only when the escapement fork releases the restriction on the escapement wheel can the detection runner rotate. That is, the intermittent rotation of the detection runner is controlled by the escapement fork.

[0007] Further, an escapement wheel is also provided on the side of the detection runner connected to the driven disk. An escapement fork is rotatably provided on the front column. The escapement fork cooperates with the escapement wheel. A rope is connected to the rotating shaft of the escapement fork. The rope is located between the front column and the rear column. One end of the rope is connected to a spring, and the other end of the rope is connected to an iron block. There is a positioning slideway on the device bracket. The iron block is slidably installed in the positioning slideway. An electromagnet is provided at the bottom of the positioning slideway. The electromagnet is electrically connected to a control system. Each time the control system controls the electromagnet to be powered on, the electromagnet attracts the iron block. The iron block pulls the escapement fork to rotate through the rope. After the electromagnet is powered on, the spring pulls the escapement fork to reset through the rope. That is, the escapement fork swings back and forth once, and the detection runner rotates once. The angle of rotation of the detection runner is the included angle between two adjacent electric heaters on the detection runner.

[0008] Furthermore, a housing is provided on the equipment support. The detection rod group includes an auxiliary swing rod, a working rocker, a driving rocker, and a crank disc. The auxiliary swing rod is rotatably installed on the housing. The working rocker is composed of a main rocker and a sub-rocker. The main rocker and the sub-rocker are linearly installed. The driving rocker is composed of a power rocker and a chute rocker. The power rocker and the chute rocker are connected in an L shape. The connection between the power rocker and the chute rocker is rotatably connected to the equipment support. The driving chain drives the driving sprocket to rotate. The driving sprocket drives the driven sprocket connected to the crank disc to rotate through the driven chain. When the crank disc rotates, it drives the adjusting slider to rotate. The adjusting slider drives the chute rocker to swing. The driving rocker drives the working rocker to swing. The working rocker further drives the electromagnetic jaw to move repeatedly.

[0009] Furthermore, the crank disc is rotatably installed on the equipment support. A driven sprocket is coaxially connected to one side of the crank disc. An adjusting slider is slidably arranged inside the crank disc. An adjusting bolt is rotatably installed on the crank disc. The adjusting bolt is threadedly connected to the adjusting slider. The auxiliary swing rod is rotatably connected to one end of the main rocker. One end of the main rocker is rotatably connected to the power rocker. A through groove is provided on the chute rocker. The adjusting slider is slidably connected to the through groove. The operator changes the distance between the adjusting slider and the rotation center of the crank disc by rotating the adjusting bolt, 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 movement trajectory of the electromagnetic jaw at the end of the sub-rocker approaches a straight line within a certain range. The temperature sensor on the electromagnetic jaw scans and detects the surface of the electric heater. By detecting the temperature of the surface of the electric heater, it is judged whether the heater is working properly.

[0010] Furthermore, an electromagnetic jaw is provided at the end of the sub-rocker away from the main rocker. A flexible clamping block is provided on the electromagnetic jaw. The temperature sensor is installed on the electromagnetic jaw. The electromagnetic jaw is electrically connected to the control system. The lengths of the power rocker, the chute rocker, the main rocker, and the sub-rocker are the same. The length of the auxiliary swing rod is twice the length of the main rocker. If the electric heater works properly, the working rocker returns normally. If there is a defect in the electric heater, the control system will control the electromagnetic jaw to be energized and work during the return process of the working rocker. The flexible clamping block clamps the end of the electric heater and pulls the defective electric heater out of the insertion hole of the detection runner during the return swing, and puts the defective electric heater into the collection box.

[0011] Furthermore, the power assembly includes a servo motor, a driving sprocket, and two driving sprockets. The two driving sprockets are respectively located directly below the two driven sprockets. Each driving sprocket is composed of two sprocket combinations. A driven chain is connected between the driving sprocket and the driven sprocket. The driving sprocket is installed on the servo motor. The same driving chain is connected between the driving sprocket and the two driving sprockets.

[0012] Furthermore, a contact switch is provided at the rotational mounting position of the auxiliary swing rod and the housing. The contact switch is electrically connected to the control system circuit. When the working joystick swings back to the end, the auxiliary swing rod touches the contact switch, and the contact switch controls the electromagnet to be energized. That is, every time the working joystick drives the electromagnetic gripper to scan and detect an electric heater, the detection runner rotates once, and a new electric heater is selected for the next round of detection. The blanking robot pulls out the electric heater remaining on the insertion hole of the detection runner and places it on the conveyor line for subsequent manufacturing processes. By driving the detection runner and the detection rod group to cooperate and operate through the power assembly, the detection and screening of the electric heater are realized, improving the detection efficiency and detection accuracy of the electric heater.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0014] The active disk is used to provide a rotating circumferential force to the detection runner through magnetic force transmission. Every time the working joystick drives the temperature sensor in the electromagnetic gripper to scan and detect an electric heater, the escapement fork controls the intermittent rotation of the detection runner. If the electric heater works normally, the working joystick returns normally. If the electric heater has defects, the control system will control the electromagnetic gripper to clamp the end of the electric heater during the return process of the working joystick, and pull out the electric heater from the insertion hole of the detection runner during the backswing process. By driving the detection runner and the temperature sensor in the detection rod group to cooperate and operate through the power assembly, the detection and screening of the electric heater are realized, improving the detection efficiency and detection accuracy of the electric heater.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-8 , the present invention provides a technical solution: an electric heater detection device with a classification and screening function, including an equipment bracket, a loading robot, an unloading robot and a number of electric heaters to be detected. A detection runner 1, a power component and a detection rod group are installed on the equipment bracket. Insertion holes are evenly distributed in a ring on the detection runner 1. A contact circuit (not shown in the figure) is provided inside the detection runner 1. The loading robot inserts the electric heater into the insertion hole, and the unloading robot takes out the detected electric heater. The power component drives the detection runner 1 to rotate intermittently. A temperature sensor is installed on the detection rod group, and the temperature sensor detects the electric heater. After the loading robot inserts the electric heater to be detected into the insertion hole, the electric heater is connected and conducted with the contact circuit, and the electric heater starts to heat. After a period of heating, the electric heater moves to the bottom along with the detection runner 1, and the detection rod group detects the electric heater through the temperature sensor.

[0027] The equipment support is provided with a front column 3 and a rear column 4. A support shaft 2 is arranged above the front column 3 and the rear column 4. The detection runner 1 is rotatably installed on the support shaft 2. A driven disk 5 is installed at one end of the detection runner 1 away from the insertion hole. A driving disk 6 is sleeved and installed on the support shaft 2. A plurality of pairs of magnets are evenly arranged in a ring on one side of the driven disk 5 close to the driving disk 6. The magnetic poles of two adjacent magnets facing the outside are opposite. The structure of the driving disk 6 is the same as that of the driven disk 5. A driven bevel gear 7 is coaxially connected to one side of the driving disk 6 away from the driven disk 5. The power assembly includes a driving bevel gear ring 8 and a driven sprocket 28. The driving bevel gear ring 8 is installed on the equipment support. The driving bevel gear ring 8 is meshed with the driven bevel gear 7 for transmission. A driven sprocket 28 is coaxially connected to one side of the driving bevel gear ring 8 away from the rear column 4. After the servo motor 24 is powered on, it drives the driving sprocket 25 to rotate. The driving sprocket 25 drives the linkage sprocket 27 to rotate through the driving chain 26. The linkage sprocket 27 drives the driven sprocket 28 connected to the driving bevel gear ring 8 to rotate through the driven chain 29. The driven sprocket 28 drives the driving bevel gear ring 8 to rotate. The driving bevel gear ring 8 drives the driven bevel gear 7 to rotate. Since the diameter of the driving bevel gear ring 8 is larger than that of the driven bevel gear 7, the driven bevel gear 7 drives the driving disk 6 to rotate rapidly. The driving disk 6 can drive the driven disk 5 to move through magnetic force transmission. Since the escapement wheel 9 is restricted by the escapement fork 10, both the detection runner 1 and the driven disk 5 are restricted by the escapement wheel 9. Therefore, the detection runner 1 cannot rotate. The driving disk 6 can only provide a circumferential force for the detection runner 1 to rotate through magnetic force transmission. Only when the escapement fork 10 releases the restriction on the escapement wheel 9 can the detection runner 1 rotate. That is, the intermittent rotation of the detection runner 1 is controlled by the escapement fork 10.

[0028] An escapement wheel 9 is also arranged on one side of the detection runner 1 connected to the driven disk 5. An escapement fork 10 is rotatably arranged on the front column 3. The escapement fork 10 is matched 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 with a spring 12, and the other end of the rope 11 is connected with an iron block 13. There is a positioning slideway on the equipment support. The iron block 13 is slidably installed in the positioning slideway. An electromagnet 14 is arranged at the bottom of the positioning slideway. The electromagnet 14 is electrically connected to a control system. Each time the control system controls the electromagnet 14 to be powered on, the electromagnet 14 attracts the iron block 13. The iron block 13 drives the escapement fork 10 to rotate through the rope 11. After the electromagnet 14 is powered on, the spring 12 drives the escapement fork 10 to reset through the rope 11. That is, the escapement fork 10 swings back and forth once, and the detection runner 1 rotates once. The rotation angle of the detection runner 1 is the included angle between two adjacent electric heaters on the detection runner 1.

[0029] A housing 15 is provided on the equipment support. The detection rod group includes an auxiliary swing rod 16, a working rocker, a driving rocker, and a crank disc 21. The auxiliary swing rod 16 is rotatably installed on the housing 15. The working rocker is composed of a main rocker 171 and a sub-rocker 172. The main rocker 171 and the sub-rocker 172 are installed in a straight line. The driving rocker is composed of a power rocker 201 and a chute rocker 202. The power rocker 201 and the chute rocker 202 are connected in an L shape. The connection part of the power rocker 201 and the chute rocker 202 is rotatably connected to the equipment support. The crank disc 21 is rotatably installed on the equipment support. A driven sprocket 28 is coaxially connected to one side of the crank disc 21. An adjusting slider 23 is slidably arranged in the crank disc 21. An adjusting bolt 22 is rotatably installed on the crank disc 21. The adjusting bolt 22 is threadedly connected to the adjusting slider 23. The auxiliary swing rod 16 is rotatably connected to one end of the main rocker 171. One end of the main rocker 171 is rotatably connected to the power rocker 201. A through groove is formed on the chute rocker 202. The adjusting slider 23 is slidably connected to the through groove. A contact switch (not shown in the figure) is provided at the rotatable installation part of the auxiliary swing rod 16 and the housing 15. The contact switch is electrically connected to the control system circuit.

[0030] The driving chain 26 drives the linkage sprocket 27 to rotate. The linkage sprocket 27 drives the driven sprocket 28 connected to the crank disc 21 to rotate through the driven chain 29. When the crank disc 21 rotates, it drives the adjusting slider 23 to rotate. The adjusting slider 23 drives the chute rocker 202 to swing. The driving rocker drives the working rocker to swing. The working rocker further drives the electromagnetic gripper 18 to move repeatedly. The operator changes the distance from the adjusting slider 23 to the rotation center of the crank disc 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 movement trajectory of the electromagnetic gripper 18 at the end of the sub-rocker 172 approaches a straight line within a certain range. The temperature sensor on the electromagnetic gripper 18 scans and detects the surface of the electric heater. By detecting the temperature of the surface of the electric heater, it is judged whether the heater is working properly.

[0031] An electromagnetic gripper 18 is provided at one end of the auxiliary rocker 172 away from the main rocker 171. A flexible gripper block 19 is provided on the electromagnetic gripper 18. The temperature sensor is installed on the electromagnetic gripper 18. The electromagnetic gripper 18 is electrically connected to the control system circuit. The lengths of the power rocker 201, the chute rocker 202, the main rocker 171, and the auxiliary rocker 172 are the same. The length of the auxiliary swing rod 16 is twice the length of the main rocker 171. The power assembly includes a servo motor 24, a driving sprocket 25, and two linkage sprockets 27. The two linkage sprockets 27 are respectively located directly below the two driven sprockets 28. Each linkage sprocket 27 is composed of two sprockets. A driven chain 29 is connected between the linkage sprocket 27 and the driven sprocket 28. The driving sprocket 25 is installed on the servo motor 24. The same driving chain 26 is connected between the driving sprocket 25 and the two linkage sprockets 27. If the electric heater works normally, the working rocker returns normally. If there is a defect in the electric heater, the control system will control the electromagnetic gripper 18 to be energized during the return of the working rocker. The flexible gripper block 19 clamps the end of the electric heater and pulls the electric heater out of the insertion hole of the detection runner 1 during the backswing process, and puts the defective electric heater into a collection box (not shown in the figure). When the working rocker swings back to the end, the auxiliary swing rod 16 touches the contact switch, and the contact switch controls the electromagnet 14 to be energized. That is, every time the working rocker drives the electromagnetic gripper 18 to scan and detect an electric heater, the detection runner 1 rotates once, and a new electric heater is replaced for the next round of detection. The blanking robot pulls out the electric heater remaining in the insertion hole of the detection runner 1 and places it on the conveyor line for subsequent manufacturing processes. By driving the detection runner 1 to cooperate with the detection rod group through the power assembly, the detection and screening of the electric heater are realized, and the detection efficiency and detection accuracy of the electric heater are improved.

[0032] Working principle of the present invention: After the feeding robot inserts the electric heater to be detected into the insertion hole, the electric heater is connected and conducted with 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 runner 1. The detection rod group detects the electric heater through the temperature sensor. After the servo motor 24 is powered on, it drives the driving sprocket 25 to rotate. The driving sprocket 25 drives the driven sprocket 27 to rotate through the driving chain 26. The driven sprocket 27 drives the driven sprocket 28 connected to the driving bevel gear ring 8 to rotate through the driven chain 29. The driven sprocket 28 drives the driving bevel gear ring 8 to rotate, and the driving bevel gear ring 8 drives the driven bevel gear 7 to rotate. Since the diameter of the driving bevel gear ring 8 is larger than that of the driven bevel gear 7, the driven bevel gear 7 drives the driving disk 6 to rotate rapidly. The driving disk 6 can drive the driven disk 5 to move through magnetic drive. Since the escapement wheel 9 is restricted by the escapement fork 10, and both the detection runner 1 and the driven disk 5 are restricted by the escapement wheel 9, the detection runner 1 cannot rotate. The driving disk 6 can only provide a circumferential force for the detection runner 1 to rotate through magnetic drive. Only when the escapement fork 10 releases the restriction on the escapement wheel 9 can the detection runner 1 rotate, that is, the intermittent rotation of the detection runner 1 is controlled by the escapement fork 10.

[0033] Each time the control system controls the electromagnet 14 to be powered on, the electromagnet 14 attracts the iron block 13, and the iron block 13 drives the escapement fork 10 to rotate through the rope 11. After the electromagnet 14 is powered on, the spring 12 drives the escapement fork 10 to reset through the rope 11, that is, the escapement fork 10 swings back and forth once, and the detection runner 1 rotates once. The rotation angle of the detection runner 1 is the included angle between two adjacent electric heaters on the detection runner 1. The driving chain 26 drives the driven sprocket 27 to rotate. The driven 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. The adjusting slider 23 drives the chute rocker 202 to swing, and the driving rocker drives the working rocker to swing. The working rocker further drives the electromagnetic jaw 18 to move repeatedly.

[0034] The operator changes the distance between the adjusting slider 23 and the rotation center of the crank disc 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 movement trajectory of the electromagnetic gripper 18 at the end of the auxiliary rocker 172 approaches a straight line within a certain range. The temperature sensor on the electromagnetic gripper 18 scans and detects the surface of the electric heater. By detecting the temperature of the surface of the electric heater, it is judged whether the heater is working normally. If the electric heater is working normally, the working rocker returns normally. If the electric heater has defects, the control system will control the electromagnetic gripper 18 to be energized during the return of the working rocker. The flexible clamping block 19 clamps the end of the electric heater and pulls the electric heater out of the insertion hole of the detection runner 1 during the return swing, and puts the defective electric heater into the collection box. The auxiliary swing rod 16 touches the contact switch when the working rocker swings back to the end. The contact switch controls the electromagnet 14 to be energized. That is, every time the working rocker drives the electromagnetic gripper 18 to scan and detect an electric heater, the detection runner 1 rotates once, and a new electric heater is replaced for the next round of detection. The blanking robot pulls out the electric heater remaining on the insertion hole of the detection runner 1 and places it on the conveying line for subsequent manufacturing processes. The detection runner 1 and the detection rod group are driven by the power assembly to cooperate and run, realizing the detection and screening of the electric heater, and improving the detection efficiency and detection accuracy of the electric heater.
