[0047] To more clearly illustrate the technical solution of the present invention, a preferred embodiment is provided below for reference. Figures 1-12An electric furnace assembly, testing, and packaging line includes an assembly line 1, a testing line 2, a labeling line 3, and a packing line 4 arranged sequentially, wherein:

[0048] Assembly line 1 is used to assemble and manufacture electric furnaces;

[0049] The testing production line 2 includes a second frame 21, a transmission device 22, a soundproof chamber 23, a swing machine 24, and several electrical testing devices 25. The second frame 21 is made of metal. Several electrical testing devices 25 are mounted on the second frame 21. The transmission device 22 is mounted on the second frame 21 and is used to drive the electrical testing devices 25 to move along the length of the second frame 21. The soundproof chamber 23 is located in the middle of the second frame 21 and has perforations at the positions corresponding to the electrical testing devices 25. The transmission device 22 can drive the electrical testing devices 25 to enter or exit the soundproof chamber 23 through the perforations. A first decibel detector is installed inside the soundproof chamber 23. The swing machine 24 is located in the middle of the second frame 21. Preferably, the swing machine 24 is located at the rear of the soundproof chamber 23. The swing machine 24 is used to drive the electric furnace on the electrical testing devices 25 to swing. Feeding mechanisms 26 are provided at both ends of the testing production line 2.

[0050] The labeling production line 3 includes a second conveying device 31 and a labeling device 32, with the labeling device 32 located outside the second conveying device 31;

[0051] The packaging line 4 includes a third conveying device 41 and a packaging device 42, with the packaging device 42 located outside the third conveying device 41.

[0052] The working process of the electric furnace assembly, testing, and packaging line involved in this invention is as follows: Workers cooperate with automated equipment to assemble and prepare the electric furnace at assembly line 1; subsequently, the feeding mechanism 26 transports the prepared electric furnace from assembly line 1 to the electrical testing device 25 on testing line 2. The electric furnace can be electrically connected to the electrical testing device 25, which supplies power to the furnace to confirm its normal operation. After completing the electrical testing, the electric furnace remains in the start-up state, while the electrical testing device 25, driven by the transmission device 22, moves the furnace, causing it to enter the interior of a soundproof chamber 23 through a perforation. The soundproof chamber 23 essentially isolates external sound, leaving only the sound generated by the electric furnace during operation. A first decibel detector detects the operating sound of the electric furnace to determine whether its operating volume exceeds the standard. The first decibel detector is connected to... A first alarm is connected. When the operating sound of the electric furnace exceeds the set decibel value, the first alarm will sound an alarm. After the volume test is completed, the electric furnace is then conveyed to the swing machine 24. The swing machine 24 lifts the electric furnace and controls it to swing. By analyzing whether there are abnormal noises inside the electric furnace during the swing, it is determined whether there are screws or other parts that have fallen off inside the electric furnace. In the electrical test, volume test and swing test, the electric furnace that fails is directly removed from the inspection production line 2, while the electric furnace that passes is conveyed by the feeding mechanism 26 to the second conveying device 31. The second conveying device 31 moves the electric furnace to the labeling device 32 for labeling. After labeling is completed, the second conveying device 31 conveys the electric furnace to the third conveying device 41. The third conveying device 41 moves the electric furnace to the packing device 42, where the packing device 42 packs the electric furnace. This application rationally combines assembly line 1, testing line 2, labeling line 3, and packing line 4, allowing the entire production process of electric furnaces from preparation to packaging to be completed on a single production line. This makes the entire production process smoother and more organized, eliminating the need to transfer electric furnaces to different equipment and thus improving production efficiency. In addition, this application optimizes the structure of testing line 2, enabling the accurate screening of defective products that cannot be powered on normally, have unstable structures, or produce excessive operating noise. This ensures that all output electric furnaces are high-quality products, thereby protecting the interests of consumers.

[0053] In this embodiment, the assembly line 1 includes two first conveying devices 11 arranged side by side and two transfer devices 12 located at both ends of the first conveying devices 11. The first conveying device 11 includes a first frame and a first transmission belt. The first transmission belt is connected to the first frame. The first frame is provided with a first driving mechanism that drives the first transmission belt to rotate. Several tooling plates are placed on the first transmission belt. The transfer device 12 includes a base 121, a transfer trolley 122 and two lifting trolleys 123. The transfer trolley 122 is mounted on the base 121. The two lifting trolleys 123 are distributed on both sides of the transfer trolley 122. The base 121 is provided with a lifting mechanism that drives the lifting trolleys 123 to move up and down. The positions of the two lifting trolleys 123 correspond to the positions of the two first conveying devices 11. The transfer trolley 122 and the lifting trolley 123 have the same structure, both including a body 1231 and two sets of transmission components 1232 located on both sides of the body 1231. The transmission direction of the transmission components 1232 is perpendicular to the transmission direction of the first conveying device 11.

[0054] Furthermore, the transmission component 1232 consists of a transmission belt, a transmission motor, and two drive wheels; both drive wheels are rotatably connected to the vehicle body 1231, the transmission belt is connected to the two drive wheels, and the transmission motor is mounted on the vehicle body 1231 to drive either drive wheel to rotate.

[0055] Furthermore, a number of detection cameras are provided above the first conveying device 11, and all of the detection cameras are mounted on the first frame. A second alarm is provided on the outside of the detection cameras and is mounted on the first frame. A controller is installed on the first frame, and both the detection cameras and the second alarm are electrically connected to the controller.

[0056] In practical applications, the first conveyor device 11 is divided into several workstations, each equipped with either a worker or an automatic assembly machine. The first transmission belt drives the tooling plate to move, allowing it to reach various workstations for the assembly of different parts. During the assembly process, after the tooling plate stops at each workstation, a detection camera takes a picture of the semi-finished product on the tooling plate and transmits the image to the controller. The controller analyzes whether there are any differences between the actual captured image and the preset structure (e.g., whether there is a significant deviation between the position of a newly installed component and the preset position, or whether there are missing locking screws, etc.). When an abnormality is detected, the second alarm will sound an alarm to remind the worker to conduct an inspection, thereby improving the yield rate of the manufactured electric furnaces. When the first transmission belt drives the tooling plate... When the plate moves to the end of the first conveyor 11, the lifting mechanism drives the lifting trolley 123 to rise, thereby lifting the tooling plate. Then, the conveyor motor starts, causing the conveyor belt to run, thereby moving the tooling plate to the fixed trolley. The fixed trolley then uses the transmission component 1232 to transport the tooling plate to another lifting trolley 123. Next, the lifting mechanism drives the lifting trolley 123 carrying the tooling plate to descend, placing the tooling plate on the second conveyor 11 for subsequent assembly of other components. When the tooling plate moves to the end of the second conveyor 11, it means that the electric furnace has completed the loading of all parts. At this time, the electric furnace can be transported to the testing production line 2 by the feeding mechanism 26, while the tooling plate is transported back to the first conveyor by another transfer device 12. Using the design of this application, the length of the assembly production line 1 is significantly shortened, thereby shortening the overall length of the electric furnace assembly, testing, and packaging line, making it easier to install in the workshop.

[0057] In this embodiment, the electrical testing device 25 includes an electrical testing tray 251, which is connected to the transmission device 22. A conductive brush 254 is provided at its bottom, and a socket 253 is provided at its top. The conductive brush 254 includes a copper conductor and several copper wires connected to the copper conductor. The socket 253 is electrically connected to the copper conductor. A conductive copper busbar 255 is installed on the second frame 21, located below the electrical testing tray 251 and electrically connected to the conductive brush 254. It should be understood that the electrical testing tray 251 can be made of bakelite, plastic, or metal, etc.

[0058] Furthermore, the top of the electrical test plate 251 is provided with a positioning block 252, which is L-shaped.

[0059] Furthermore, a temperature sensor is provided on the electrical testing plate 251.

[0060] In practical applications, after the feeding mechanism 26 transports the electric furnace from the assembly line 1 to the electrical testing tray 251, the electric furnace is positioned by the L-shaped positioning block 252. Then, the transmission device 22 drives the electrical testing tray 251 to move to the testing station. At this time, the conductive brush 254 on the electrical testing tray 251 contacts the conductive copper busbar 255 on the second frame 21, so that the socket 253 is connected to the power supply. When the operator inserts the power plug of the electric furnace into the socket 253, the electric furnace can obtain power and start up. Then, the heating temperature and heating efficiency are detected manually or by using a temperature sensor to determine whether the electric furnace is qualified. The design of this application can effectively screen out electric furnaces that cannot generate heat properly. In addition, this application uses copper wire as the bristle structure of the conductive brush 254. The copper wire has a small diameter and a certain degree of elastic deformation. Therefore, when the conductive brush 254 moves to the corresponding position of the conductive copper busbar 255, the copper wire can deform and thus make close contact with the conductive copper busbar 255, ensuring the electrical conduction of the socket 253, thereby improving the accuracy of detection. Moreover, under long-term use, there will be no mutual wear between the conductive brush 254 and the conductive copper busbar 255, which improves the service life of the conductive structure.

[0061] In this embodiment, the second frame 21 is also equipped with several blocking mechanisms for limiting the movement of the electrical testing tray 251. The blocking mechanism includes a first telescopic driver and a baffle. The baffle is connected to the first telescopic driver and is driven to move up and down by the first telescopic driver. In practical applications, the baffle blocks the electrical testing tray 251, ensuring that it stops precisely after moving to the next workstation. While the electrical testing tray 251 is moving, the first telescopic driver drives the baffle downwards, thus preventing the baffle from obstructing the movement of the electrical testing tray 251. It should be understood that the first conveying device 11 is also equipped with a blocking mechanism to limit the movement of the tooling plate.

[0062] In this embodiment, the transmission device 22 includes a second transmission belt, which is connected to the second frame 21. The electrical measuring device 25 is placed on the second transmission belt. The second frame 21 is provided with a second drive mechanism that drives the second transmission belt to rotate. There are two sets of transmission devices, which are distributed vertically and are both connected to the second frame 21. The two ends of the second frame 21 are respectively provided with return plate mechanisms 27. The return plate mechanism 27 includes a second telescopic driver 271 and a return plate trolley 272. The return plate trolley 272 is connected to the second telescopic driver 271 and is driven to move up and down by the second telescopic driver 271. The return plate trolley 272 includes a vehicle body and two sets of transmission components arranged on both sides of the vehicle body.

[0063] In practical applications, the electrical testing tray 251 contacts the second transmission belt, which drives the electrical testing tray 251 to move. This allows the electric furnace on the electrical testing tray 251 to sequentially perform electrical testing, volume testing, and sway testing. When the electrical testing tray 251 moves to the end of the second frame 21, it indicates that the electric furnace has completed the above tests. The electric furnace can then be transported to the second conveyor 31 via the feeding mechanism 26. The electrical testing tray 251 continues to move under the action of the second transmission belt until it reaches the return tray trolley 272. Subsequently, the second telescopic driver 271 drives the return tray trolley 272 downward, aligning the electrical testing tray 251 with the second transmission belt below. The return tray trolley 272 uses a transmission component to control the movement of the electrical testing tray 251 onto the second transmission belt. Using the design of this application, the electrical testing tray 251 can be automatically transported back by the second transmission belt below, achieving automatic return and eliminating the need for manual handling of the electrical testing tray 251, thus reducing workload.

[0064] As another preferred embodiment, the transmission device 22 includes a transmission chain, which is driven to the second frame 21. The electrical testing tray 251 is fixedly connected to a link on the transmission chain. The second frame 21 is equipped with a second drive mechanism that drives the transmission wheel to rotate. With the above design, the upper part of the transmission chain can drive the electrical testing tray 251 to move forward, while the lower part of the transmission chain can drive the electrical testing tray 251 to move backward, thereby realizing the automatic return of the electrical testing tray 251.

[0065] In this embodiment, the swing machine 24 includes a support 241, a movable plate 244, and a swing frame 242. The support 241 is located outside the second frame 21. The movable plate 244 is hinged to the support 241. The swing frame 242 is located above the electrical measuring device 25 and is slidably connected to the movable plate 244. The movable plate 244 is provided with a fifth telescopic driver that drives the swing frame 242 to move up and down. The support 241 is equipped with a first rotary driver 243 that drives the movable plate 244 to rotate. The bottom of the swing frame 242 is provided with two clamping arms 245, which are slidably connected to the swing frame 242. The swing frame 242 is provided with a fourth telescopic driver that drives the two clamping arms 245 to move closer or further away from each other. The ends of the clamping arms 245 are provided with a second rotary driver 246, and the output end of the second rotary driver 246 is provided with a clamping member 247.

[0066] Furthermore, both the first rotary driver 243 and the second rotary driver 246 are servo motors, and the servo motors are equipped with a noise reduction structure. The noise reduction structure includes a soundproof cover and a buffer pad. The soundproof cover is placed outside the servo motor and is used to isolate the noise generated by the rotor inside the servo motor during operation. The buffer pad is placed between the servo motor and the bracket 241 and acts as a buffer for the servo motor, reducing the vibration amplitude of the servo motor, thereby reducing the noise generated by the vibration of the servo motor.

[0067] Furthermore, the clamping element 247 includes an electromagnet. It should be understood that the electric furnace itself is not very strong. If a strong clamping force is applied directly to the electric furnace to clamp it, it is easy to scratch the electric furnace and affect its appearance. Therefore, this application uses the clamping arm 245 and the electromagnet to apply a certain clamping force and magnetic attraction force to the electric furnace. Under the cooperation of the two forces, the electric furnace can be stably driven to swing, and the electric furnace can be prevented from being scratched.

[0068] Furthermore, the testing line 2 also includes a soundproof testing room, which is located in the middle of the second frame 21, and the swing machine 24 is located inside the soundproof testing room.

[0069] In practical applications, after the electric furnace undergoes noise detection, the transmission device 22 moves it to the corresponding position on the swing machine 24. At this time, the fifth telescopic actuator drives the swing frame 242 downward, causing the two clamping arms 245 to move to both sides of the electric furnace. The fourth telescopic actuator then drives the two clamping arms 245 to move closer together, so that the electromagnet and the electric furnace are in close contact. When the electromagnet is energized, it generates magnetism, thereby forming a clamping force and magnetic attraction. The electric furnace is clamped by the cooperation of these two forces. Subsequently, the fifth telescopic actuator drives the clamping arms 245 upward, causing the electric furnace to separate from the electric measuring plate 251. Then, the second rotation... The actuator 246 is activated, causing the electric furnace to swing left and right. After a certain number of swings, the first rotary actuator 243 is activated, causing the swing frame 242 to swing back and forth, thus causing the electric furnace to swing back and forth. Because the soundproof testing chamber 248 essentially isolates external noise, and both the first rotary actuator 243 and the second rotary actuator 246 are equipped with sound-absorbing structures, when a part falls inside the electric furnace, the abnormal noise produced by the collision of the part with other components can be clearly heard during the swing test. By manually listening to whether there is an abnormal noise, it can be determined whether a part has fallen inside the electric furnace. Preferably, a second decibel detector can also be installed in the soundproof testing chamber 248 to detect the volume inside the soundproof testing chamber 248, thereby determining whether there is an abnormal noise and analyzing whether a part has fallen inside the electric furnace.

[0070] As another preferred option, the swing machine 24 can also be equipped with a multi-degree-of-freedom robotic arm. The output end of the multi-degree-of-freedom robotic arm is equipped with a material handling mechanism, which includes an electromagnet. In practical applications, the electric furnace is lifted by the material handling mechanism, and then the multi-degree-of-freedom robotic arm is used to drive the electric furnace to swing, thereby determining whether any parts have fallen out of the electric furnace.

[0071] In this embodiment, the feeding mechanism 26 is located above the electrical measuring device 25, and includes a transverse frame 261, a transverse drive component 262, a third telescopic driver 263, and a picking component 264. The transverse frame 261 is slidably connected to the second frame 21. The transverse drive component 262 is mounted on the second frame 21 and is used to drive the transverse frame 261 to move laterally. The third telescopic driver 263 is mounted on the transverse frame 261 and is used to drive the picking component 264 to move up and down. The picking component 264 includes an electromagnet.

[0072] In practical applications, after the first transmission belt transports the tooling plate to one end near the feeding mechanism 26, the transverse drive component 262 drives the transverse frame 261 to move, causing the picking component 264 to move above the tooling plate. Then, the third telescopic drive 263 drives the picking component 264 downward to pick up the electric furnace on the tooling plate. Then, with the cooperation of the transverse drive component 262 and the third telescopic drive 263, the electric furnace moves onto the electric testing tray 251 for testing.

[0073] The above description is only a preferred embodiment of the present invention, and its structure is not limited to the shapes listed above. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
