Description

Technical Field

[0001] This invention relates to the field of meat grinder production and testing technology, and in particular to a test line for a meat grinder. Background Technology

[0002] As a small kitchen appliance, meat grinders must undergo performance tests, including power-on operation and noise levels, before leaving the factory. Currently, the most common testing methods for meat grinders on the market are manual operation, which is inefficient and easily affected by interference, making it difficult to meet the needs of rapid testing for large-scale production.

[0003] To improve testing efficiency, meat grinder testing lines have emerged in recent years. Existing meat grinder testing typically utilizes conveyor belts and detection structures to transport and test the grinder, achieving a certain degree of automation. However, in actual testing, manual insertion of the plug into the corresponding socket is still required to power the grinder. This process is cumbersome and labor-intensive, and frequent plugging and unplugging can cause wear or damage to the plug, thus affecting the smooth progress of the test and the subsequent use of the grinder. Summary of the Invention

[0004] The main objective of this invention is to propose a test line for meat grinders, which aims to improve the automation level of meat grinder testing and enhance the reliability of the test line.

[0005] To achieve the above objectives, the present invention proposes a test line for a meat grinder, comprising:

[0006] abutment;

[0007] A conveying assembly is disposed on the base;

[0008] A fixture, movably mounted on the conveying assembly, includes a tray and a simulated socket disposed on the tray. The tray supports the meat grinder, and the simulated socket is capable of being plugged into the meat grinder.

[0009] A test component is provided on the base and arranged along the conveying path of the conveying component. The test component includes a power-on structure and a test structure. The power-on structure can be plugged into the analog socket to supply power to the plug. The test structure is used to test the performance of the meat grinder.

[0010] In one embodiment, the outer periphery of the plug is provided with a limiting protrusion, and the simulated socket includes:

[0011] A fixed base is provided on the tray, and the fixed base is provided with a first insertion hole for the plug pins to be inserted;

[0012] A movable block, movably disposed on the upper surface of the fixed base, has a notch on the side facing the plug to avoid the plug, and the side of the movable block facing the fixed base can abut against the side of the limiting protrusion facing away from the fixed base; and

[0013] A locking element is movably disposed in the simulated socket and capable of locking the movable block, such that the movable block can cooperate with the simulated socket to restrict the movement of the limiting protrusion, thereby locking the plug in the first socket.

[0014] In one embodiment, the simulated socket further includes a positioning cylinder disposed on the fixed base, with an opening at the bottom of the positioning cylinder; the power-on structure includes:

[0015] power supply;

[0016] The first mounting base is movable and height-adjustable on the base;

[0017] A positioning post is provided on the first mounting base;

[0018] A conductive post is movably mounted on the first mounting base and electrically connected to the power supply, and the end of the conductive post is provided with a recess;

[0019] A first driving structure, disposed on the base and drivenly connected to the first mounting seat, is capable of driving the first mounting seat to move the conductive post and the positioning post closer to the fixed base, so that the positioning post is inserted into the positioning cylinder and the conductive post is aligned with the pins of the plug; and

[0020] The second driving structure is disposed on the first mounting base and drivenly connected to the conductive post. It can drive the conductive post to move close to the pin of the plug and insert into the first socket so that the recess abuts against the pin of the plug.

[0021] In one embodiment, the test components are provided in two sets along the conveying path of the conveying components. The test structure in one test component is used to test the noise of the meat grinder, and the test structure in the other test component is used to test the button life, speed and insulation of the meat grinder.

[0022] In one embodiment, one of the test components includes a soundproof room, and the test structure includes a first mechanical gripper structure and a sound sensor disposed inside the soundproof room. The first mechanical gripper structure is capable of gripping the knob of the meat grinder and rotating the knob to switch the gear of the meat grinder, and the sound sensor is used to detect the sound of the meat grinder at different gears.

[0023] In one embodiment, the test structure of another test component includes a button striking structure for detecting the button life of the meat grinder, a rotational speed test structure for detecting the rotational speed of the meat grinder, and a high-voltage needle structure for testing the insulation of the meat grinder, wherein the button striking structure, the rotational speed test structure, and the high-voltage needle structure are movably arranged around the meat grinder.

[0024] In one embodiment, the button striking structure includes:

[0025] The pressure sensor can be raised and lowered on the base.

[0026] A sleeve is located at the bottom of the pressure sensor;

[0027] A pressure shaft, with one end movably disposed inside the sleeve facing the pressure sensor, and the other end capable of pressing against the button of the meat grinder; and

[0028] A first elastic element is disposed inside the sleeve and connected to the end of the pressure shaft facing the pressure sensor;

[0029] When the pressure shaft presses against the first elastic element and abuts against the button of the meat grinder, the pressure sensor detects the real-time reaction force of the meat grinder button on the pressure shaft.

[0030] In one embodiment, the high-pressure needle structure includes:

[0031] High voltage instrument;

[0032] A first conductive needle is movably mounted on the base and electrically connected to the high voltage instrument. The first conductive needle can approach the meat grinder and contact the metal casing of the meat grinder.

[0033] A first conductive buffer pad is disposed at the end of the first conductive needle body that contacts the metal shell of the meat grinder;

[0034] A second conductive needle is movably mounted on the base and electrically connected to the high-voltage instrument; the first conductive needle can approach and contact the plug; and

[0035] The second conductive buffer pad is disposed at the end of the second conductive needle body that contacts the plug of the meat grinder.

[0036] In one embodiment, the conveying assembly includes a first conveying structure and a second conveying structure that is vertically mounted on the conveying path of the first conveying structure, wherein the conveying direction of the second conveying structure is perpendicular to the conveying direction of the first conveying structure;

[0037] The test assembly also includes a receiving structure, which is movably disposed on the base and has the same conveying direction as the second conveying structure. The second conveying structure is capable of conveying the fixture to the receiving structure.

[0038] In one embodiment, the test line of the meat grinder further includes:

[0039] A first positioning detection element is disposed on the base and opposite to the second conveying structure, and is used to detect whether the fixture has reached the second conveying structure;

[0040] The limiting block is configured as a triangular structure and has a first end, a second end and a third end arranged circumferentially, the first end being rotatably connected to the base;

[0041] A support roller, rotatably mounted at the second end, is capable of contacting the bottom surface of the tray and rolling along the tray; and

[0042] A driving component, disposed on the base and drivenly connected to the third end, is capable of driving the third end to rotate the second end around the first end, such that the third end abuts against the side of the tray or the supporting roller contacts the bottom surface of the tray, so as to limit or release the fixture in the second conveying structure.

[0043] The technical solution of this invention involves setting up a base, a conveying assembly, a fixture, and a testing assembly on a meat grinder testing line. The conveying assembly is located on the base; the fixture is movably mounted on the conveying assembly and includes a tray and a simulated socket on the tray. The tray supports the meat grinder, and the simulated socket can be plugged into the meat grinder's plug. The testing assembly is located on the base and arranged along the conveying path of the conveying assembly. The testing assembly includes a power-on structure and a testing structure. The power-on structure can be plugged into the simulated socket to supply power to the plug, and the testing structure is used to test the performance of the meat grinder. Compared to existing testing lines that require manual plug-and-play operation, the technical solution of this invention uses a fixture with a simulated socket. During testing, the meat grinder is placed on the tray of the fixture with its plug plugged into the simulated socket. After the conveying assembly transports the fixture to the testing assembly, the power-on structure can be plugged into the simulated socket to supply power to the meat grinder. This eliminates the need for manual intervention, improving the automation level of the meat grinder testing, avoiding frequent plug-and-play operations, reducing the risk of plug wear, and improving the reliability of the testing line.

[0068] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0069] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0070] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0071] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0072] As a small kitchen appliance, meat grinders must undergo performance tests, including power-on operation and noise levels, before leaving the factory. Currently, the most common testing methods for meat grinders on the market are manual operation, which is inefficient and easily affected by interference, making it difficult to meet the needs of rapid testing for large-scale production.

[0073] To improve testing efficiency, meat grinder testing lines have emerged in recent years. Existing meat grinder testing typically utilizes conveyor belts and detection structures to transport and test the grinder, achieving a certain degree of automation. However, in actual testing, manual insertion of the plug into the corresponding socket is still required to power the grinder. This process is cumbersome and labor-intensive, and frequent plugging and unplugging can cause wear or damage to the plug, thus affecting the smooth progress of the test and the subsequent use of the grinder.

[0074] This invention proposes a test line for meat grinders to improve the automation level of meat grinder testing and enhance the reliability of the test line.

[0075] Please see Figures 1 to 3 In one embodiment, the test line of the meat grinder 700 includes a base, a conveying assembly 100, a fixture, and a test assembly 400. The conveying assembly 100 is disposed on the base. The fixture is movably mounted on the conveying assembly 100 and includes a tray 210 and a simulated socket 220 disposed on the tray 210. The tray 210 is used to support the meat grinder 700, and the simulated socket 220 can be plugged into the plug 710 of the meat grinder 700. The test assembly 400 is disposed on the base and arranged along the conveying path of the conveying assembly 100. The test assembly 400 includes a power-on structure 410 and a test structure. The power-on structure 410 can be plugged into the simulated socket 220 to supply power to the plug 710, and the test structure is used to test the performance of the meat grinder 700.

[0076] The lower surface of the fixture's tray 210 overlaps with the conveying assembly 100. The upper surface of the tray 210 is provided with a positioning groove for placing the meat grinder 700. The shape and size of the positioning groove are designed to fit the shape and size of the meat grinder 700 to limit its movement. A simulated socket 220 is located on the upper surface of the tray 210 and is positioned close to the positioning groove to facilitate the insertion of the meat grinder 700's plug 710. Furthermore, the tray 210 is provided with a cable routing frame 230 to guide the cable of the plug 710 to the simulated socket 220, while also limiting the cable movement to prevent interference with conveying and inspection operations.

[0077] The power supply structure of the test component 400 can automatically connect to the analog socket 220 after the conveying component 100 conveys the fixture to the test component 400, so as to supply power to the plug 710 and then to the meat grinder 700, which facilitates the test structure of the test component 400 to effectively test the performance of the meat grinder 700.

[0078] The technical solution of the present invention involves setting up a base, a conveying assembly 100, a fixture, and a testing assembly 400 on the test line of a meat grinder 700. The conveying assembly 100 is located on the base; the fixture is movably mounted on the conveying assembly 100 and includes a tray 210 and a simulated socket 220 located on the tray 210. The tray 210 is used to support the meat grinder 700, and the simulated socket 220 can be plugged into the plug 710 of the meat grinder 700; the testing assembly 400 is located on the base and is arranged along the conveying path of the conveying assembly 100. The testing assembly 400 includes a power-on structure 410 and a testing structure. The power-on structure 410 can be plugged into the simulated socket 220 to supply power to the plug 710, and the testing structure is used to test the performance of the meat grinder 700. Compared to existing test leads that require manual plugging and unplugging of the plug 710, the present invention provides a fixture with a simulated socket 220. During testing, the meat grinder 700 is placed on the tray 210 of the fixture with its plug 710 connected to the simulated socket 220. After the conveying assembly 100 conveys the fixture to the test assembly 400, the power supply structure 410 can be connected to the simulated socket 220 to supply power to the meat grinder 700. This eliminates the need for manual intervention, improves the automation level of the meat grinder 700 test, avoids frequent plugging and unplugging of the plug 710, reduces the risk of wear and tear on the plug 710, and improves the reliability of the test lead.

[0079] Please see Figure 2 and Figure 3 In one embodiment, the outer periphery of the plug 710 is provided with a limiting protrusion 711. The simulated socket 220 includes a fixed base 221 disposed on the support plate 210. The fixed base 221 is provided with a first socket for the plug pins of the plug 710 to be inserted. The movable block 222 is movably disposed on the upper surface of the fixed base 221. The movable block 222 is provided with a notch on the side facing the plug 710 to avoid the plug 710. The side of the movable block 222 facing the fixed base 221 can abut against the side of the limiting protrusion 711 facing away from the fixed base 221. The locking member 223 is movably disposed on the simulated socket 220 and can lock the movable block 222, so that the movable block 222 can cooperate with the simulated socket 220 to restrict the movement of the limiting protrusion 711, thereby locking the plug 710 in the first socket.

[0080] Specifically, the fixed base 221 has two second sockets spaced apart for the insertion of the two prongs of the plug 710. The upper surface of the fixed base 221 has two connecting blocks 224. The two connecting blocks 224 are located at opposite ends of the fixed base 221 and have first grooves on their respective sides. The opposite ends of the movable block 222 have connecting protrusions, which are movably positioned in the first grooves. The connecting blocks 224 connect the movable block 222 to the fixed base 221 and allow the movable block 222 to move horizontally and vertically, facilitating its movement closer to or away from the plug 710. The fixed base 221, connecting blocks 224, and movable blocks 222 are all made of insulating material to prevent safety hazards such as electrical leakage during testing. One end of the movable block 222 has a notch with an inner diameter smaller than the outer diameter of the limiting protrusion 711, allowing the movable block 222 to abut against the limiting protrusion 711, thereby restricting the movement of the plug 710. The other end of the movable block 222 is provided with a first connecting hole, and the fixed base 221 is provided with a second connecting hole. The locking member 223 can pass through the first connecting hole and the second connecting hole to cooperate with the fixed base 221 to lock the movable block 222. In one embodiment, the locking member 223 is configured as a reset-type indexing pin. The spring of the reset-type indexing pin drives the pin head to extend and simultaneously pass through the first connecting hole and the second connecting hole to connect the fixed base 221 and the movable block 222, thereby locking the movable block 222. By pulling the button of the reset-type indexing pin, the pin head can overcome the spring force and exit the second connecting hole, thereby unlocking the movable block 222. In another embodiment, the locking member 223 can also be configured as a screw, with the second connecting hole correspondingly set as a threaded hole. The screw passes through the first connecting hole and is screwed into the second connecting hole to lock the movable block 222. The locking force of the movable block 222 can be adjusted by controlling the connection depth between the screw and the second connecting hole.

[0081] Thus, by cooperating with the movable block 222, the locking member 223 and the limiting protrusion 711 of the plug 710, the pins of the plug 710 can be restricted to the first socket, so that the simulated socket 220 can reliably support and fix the plug 710, preventing the plug 710 from loosening or falling off during the test, and ensuring the stability and accuracy of the test.

[0082] Please see Figures 2 to 4In one embodiment, the analog socket 220 further includes a positioning cylinder 225, which is disposed on the fixed base 221 and has an opening at the bottom. The power-on structure 410 includes a power supply, a first mounting base 411, a positioning post 413, a conductive post 414, a first driving structure 415, and a second driving structure 416. The first mounting base 411 is movably mounted on the base; the positioning post 413 is disposed on the first mounting base 411; the conductive post 414 is movably mounted on the first mounting base 411 and electrically connected to the power supply, and the end of the conductive post 414 has a recess. The driving structure 415 is located on the base and is driven to be connected to the first mounting base 411. It can drive the first mounting base 411 to move the conductive post 414 and the positioning post 413 closer to the fixed base 221, so that the positioning post 413 is inserted into the positioning cylinder 225 and the conductive post 414 is opposite to the pin of the plug 710. The second driving structure 416 is located on the first mounting base 411 and is driven to be connected to the conductive post 414. It can drive the conductive post 414 to move closer to the pin of the plug 710 and insert it into the first socket, so that the recess abuts against the pin of the plug 710.

[0083] Specifically, the analog socket 220 also includes a positioning block 226. The tray 210 has a mounting opening 212, which is located below the fixed base 221 and communicates with two second sockets. The positioning block 226 is located inside the mounting opening 212 and has two first clearance holes that correspond one-to-one with the two first sockets. The height of the fixed base 221 is adapted to the height of the plug pins of the plug 710 to avoid unnecessary interference between the plug pins of the plug 710 and the positioning block 226 or the tray 210. The fixed base 221 also has a second clearance hole, which is located between the two first through holes to avoid the positioning cylinder 225. The positioning cylinder 225 is hollow and located between the first clearance holes. One end of the positioning cylinder 225 is fixedly inserted through the positioning block 226 and has an opening, while the other end of the positioning cylinder 225 is closed and extends into but does not protrude from the second clearance hole to avoid interference with the plug 710. Both the positioning block 226 and the positioning cylinder 225 are made of insulating material to further ensure power supply safety.

[0084] The test assembly 400 includes a workbench, which is placed on a base and has a working position. A first mounting base 411 is vertically mounted on the workbench via a first drive structure 415. A positioning post 413 is fixed to the first mounting base 411 and protrudes from the upper surface of the first mounting base 411. A second drive structure 416 is located at the bottom of the first mounting base 411 and is drive-connected to a second mounting base 412. Two conductive posts 414 are spaced apart and protruding from the second mounting base 412. Both conductive posts 414 are electrically connected to a power source and can abut against two corresponding pins. The top of each conductive post 414 has a recess to increase the contact area with the pins and improve the stability of conductivity. The power source can be a low-voltage, high-current DC power source to meet the power requirements of the meat grinder 700 during testing, while ensuring the safety of the operator. The first drive structure 415 and the second drive structure 416 can both be configured as motors or cylinders, etc. The conductive posts 414 can be made of copper or other materials to have good conductivity; no restrictions are placed here. The positioning post 413 and the conductive post 414 are arranged parallel to each other, and the second mounting base 412 is movably inserted through the positioning post 413. The second driving structure 416 can drive the second mounting base 412 to move the conductive post 414 up and down along the positioning post 413. Further, in one embodiment, the closed end of the positioning cylinder 225 is conical, and the top end of the positioning post 413 is correspondingly set to be conical, so that when the positioning post 413 is inserted into the positioning cylinder 225, the guiding effect of the conical structure can be used to quickly and accurately complete the docking between the positioning post 413 and the positioning cylinder 225, ensuring positioning accuracy.

[0085] In the initial state, the top of the positioning post 413 is higher than the top of the conductive post 414, so that when the fixture reaches the test assembly 400 and the first drive structure 415 drives the first mounting base 411 to move the second mounting base 412 and the positioning post 413 upward, the positioning post 413 can first be inserted into the positioning cylinder 225 through the opening of the positioning cylinder 225 to achieve positioning. When the positioning post 413 abuts against the closed end of the positioning cylinder 225, the first drive structure 415 stops working so that the first mounting base 411 stops rising; at this time, the two conductive posts 414 are aligned with the two first clearance holes one by one, and the second drive structure 416 starts working to drive the second mounting base 412 to move the conductive post 414 upward and extend into the first clearance hole until the concave part of the conductive post 414 is tightly abutted against the pin of the plug 710, thereby achieving stable and reliable power supply to the meat grinder 700.

[0086] Furthermore, the meat grinder 700 production line also includes a second positioning detection element and a control system. The second positioning detection element is used to detect whether the fixture has reached the working position of the workbench in the test assembly 400. The control system is electrically connected to the second positioning detection element and the power supply structure. The working position is the location of the fixture during the testing process of the meat grinder 700 by the test assembly 400. The power supply structure is located below the working position. When the second positioning detection element detects that the fixture has reached the working position, it can send a real-time signal to the control system, enabling the control system to promptly control the power supply structure to supply power to the plug 710, ensuring the automation of the test line and the timeliness and accuracy of powering the meat grinder 700. The second detection element can be configured as a photoelectric sensor or an infrared sensor, etc., and the control system can be configured as a circuit board or controller with certain data processing and computing capabilities, etc., without limitation.

[0087] Please see Figure 1 , Figure 5 and Figure 8 In one embodiment, two sets of test components 400 are provided along the conveying path of the conveying component 100. One test component 400 has a test structure used to test the noise of the meat grinder 700, while the other test component 400 has a test structure used to test the button life, speed, and insulation of the meat grinder 700. Specifically, both sets of test components 400 are equipped with a workbench and a power supply structure. The two sets of test components 400 can perform comprehensive and orderly testing of multiple performance aspects of the meat grinder 700, and both sets of test components 400 perform automated testing of the meat grinder 700, thereby improving both the automation level and the comprehensiveness of the performance testing of the meat grinder 700.

[0088] Please see Figures 5 to 7 In one embodiment, one of the test components 400 includes a soundproof room 420, and the test structure includes a first mechanical claw structure 430 and a sound sensor 440 disposed inside the soundproof room 420. The first mechanical claw structure 430 can grip the knob 720 of the meat grinder 700 and rotate the knob 720 to switch the gear of the meat grinder 700. The sound sensor 440 is used to detect the sound of the meat grinder 700 at different gears.

[0089] Specifically, the soundproof chamber 420 includes a soundproof housing 421 and a soundproof door 422. The soundproof housing 421 has an opening to allow a fixture to enter its interior. The soundproof door 422 is adjustable and can be raised and lowered on the outer wall of the soundproof housing 421 to cover or expose the opening. A workbench is located inside the soundproof housing 421. The first mechanical gripper structure 430 and the sound sensor 440 are both located on the workbench and arranged around the work position. When the sound sensor 440 is working, the soundproof door 422 covers the opening to isolate the interior and exterior environments of the soundproof housing 421, ensuring testing accuracy. The interior of the soundproof chamber 420 is lined with sound-absorbing material to effectively reduce external noise interference and provide an accurate testing environment for the sound sensor 440. The top and / or bottom of the soundproof housing 421 have accommodating spaces to house the power supply and related electrical devices, ensuring a compact and rational overall layout. The testing assembly 400 also includes a support frame to support the soundproof housing 421 and ensure its structural stability.

[0090] The first mechanical gripper structure 430 includes a mechanical gripper body 431 and a third drive structure 432. The mechanical gripper body 431 is rotatably connected to the worktable via a first mounting bracket 435 and is capable of gripping or releasing the knob 720 of the meat grinder 700. The third drive structure 432 is mounted on the first mounting bracket 435 and is driven to the mechanical gripper body 431 to drive the mechanical gripper body 431 to rotate the knob 720. Further, the first mechanical gripper structure 430 also includes a translation drive structure 436, which is driven to the first mounting bracket 435 to drive the first mounting bracket 435 to move the mechanical gripper body 431 and the third drive structure 432 closer to or further away from the knob 720. The third drive structure 432 may include a motor, a synchronous pulley, a synchronous belt, or other structures to achieve a drive connection with the mechanical gripper body 431. The mechanical gripper body 431 may be configured as a bionic mechanical gripper, etc. The translation drive structure 436 may be configured as a motor or a linear module, etc., without limitation. A sound sensor 440 is positioned close to the grinding drum 730 of the meat grinder 700 to accurately capture the sound generated during operation. The sound sensor 440 can be configured as a high-sensitivity microphone or sound level meter to accurately measure the decibel values ​​of the sound generated by the meat grinder 700 at different speeds; no limitation is made here. Both the sound sensor 440 and the first mechanical gripper structure 430 are electrically connected to the control system. The control system controls the first mechanical gripper structure 430 to rotate the knob 720 to different speeds. The sound sensor 440 transmits the collected sound signals to the control system, allowing the control system to analyze and process the sound signals to determine whether the sound data of the meat grinder 700 at each speed is acceptable.

[0091] Furthermore, a first trigger 433 protrudes from the exterior of the robotic gripper body 431, and a first inductive switch 434, which cooperates with the first trigger 433, is provided on the worktable. The first inductive switch 434 is located on the rotation path of the robotic gripper body 431. In one embodiment, each gear position corresponds to one first inductive switch 434, and the number and position of the first inductive switches 434 are set according to the number and position of the knob 720. The first inductive switch 434 can be configured as a photoelectric switch, and the first trigger 433 is correspondingly configured as a baffle. When the robotic gripper body 431 drives the knob 720 to rotate, the first trigger 433 will sequentially trigger the corresponding first inductive switch 434. The first inductive switch 434 transmits a signal to the control system, which records the corresponding gear information and sound data to ensure the accuracy and completeness of noise detection. Simultaneously, it effectively prevents the robotic gripper body 431 from rotating excessively or insufficiently, ensuring the smooth progress of the test. In some other embodiments, only one first inductive switch 434 may be provided, and the control system may determine the real-time gear position of the knob 720 based on the number of times the first trigger 433 triggers the first inductive switch 434.

[0092] Please see Figures 8 to 12 In one embodiment, the test structure of another test component 400 includes a key striking structure 450 for detecting the key life of the meat grinder 700, a speed testing structure 460 for detecting the speed of the meat grinder 700, and a high-voltage needle structure 470 for testing the insulation of the meat grinder 700. The key striking structure 450, the speed testing structure 460, and the high-voltage needle structure 470 are movably arranged around the meat grinder 700. Specifically, the test component 400 also includes a frame, with a workbench located inside the frame. The key striking structure 450, the speed testing structure 460, and the high-voltage needle structure 470 are all arranged around the working positions of the workbench. The top and / or bottom of the frame are provided with accommodating space to accommodate power supplies and related electrical structures, ensuring the rationality and compactness of the overall layout. Further, the test component 400 includes two sets of test structures, and the workbench has two working positions, with each set of test structures arranged around one working position. The two sets of test structures can work simultaneously to simultaneously test the key life, speed, and insulation of two meat grinders 700, further improving testing efficiency.

[0093] Please see Figure 9 and Figure 10In one embodiment, the button striking structure 450 includes a pressure sensor 451, a sleeve 452, a pressing shaft 453, and a first elastic element. The pressure sensor 451 is movably mounted on the base. The sleeve 452 is located at the bottom of the pressure sensor 451. One end of the pressing shaft 453 facing the pressure sensor 451 is movably located inside the sleeve 452, and the other end can press against the button of the meat grinder 700. The first elastic element is located inside the sleeve 452 and is connected to the end of the pressing shaft 453 facing the pressure sensor 451. When the pressing shaft 453 squeezes the first elastic element and presses against the button of the meat grinder 700, the pressure sensor 451 detects the real-time reaction force of the button of the meat grinder 700 on the pressing shaft 453. Specifically, the button striking structure 450 also includes a second mounting bracket 454 and a fourth drive structure 455. The second mounting bracket 454 is mounted on the frame and located above the worktable. The pressure sensor 451 is mounted on the second mounting bracket 454 via the fourth drive structure 455. The fourth drive structure 455 can drive the pressure sensor 451 to synchronously raise and lower the sleeve 452 and the pressure shaft 453, so that the pressure shaft 453 moves closer to or away from the button of the meat grinder 700. The fourth drive structure 455 can be configured as a linear module or other structures, and is not limited here. Further, the pressure sensor 451 is provided with a second trigger 456. The second mounting bracket 454 is provided with two second inductive switches 457 that cooperate with the second trigger 456. The two second inductive switches 457 are spaced apart along the lifting stroke of the pressure sensor 451. The second inductive switch 457 away from the worktable is used to detect whether the pressure sensor 451 has reset, and the second inductive switch 457 close to the worktable is used to detect whether the pressure sensor 451 has reached the preset striking position. The preset striking position is the position corresponding to when the pressing shaft 453 fully presses down the button on the meat grinder 700. The second sensor switch 457 can be configured as a photoelectric switch, and the second trigger 456 can be configured as a baffle.

[0094] In the initial state of the button striking structure 450, the second trigger 456 triggers the second inductive switch 457 away from the worktable. When a button life test is required, the power-on structure 410 resets to disconnect the power supply to the meat grinder 700. The control system controls the fourth drive structure 455 to drive the pressure sensor 451 to move the sleeve 452 and the pressure shaft 453 downward, so that the pressure shaft 453 gradually approaches the button of the meat grinder 700 until it reaches the preset striking position. At this time, the second trigger 456 triggers the second inductive switch 457 near the worktable. At this time, the control system records the real-time reaction force data detected by the pressure sensor 451 to determine whether the force on the button of the meat grinder 700 meets the standard. After a button press test is completed, the fourth drive structure 455 drives the pressure sensor 451 to rise. When the second trigger 456 triggers the second inductive switch 457 away from the worktable again, it indicates that the pressure sensor 451 has been reset. The control system can then control the next button press test. By repeatedly testing and recording the data of each real-time reaction force, the control system can accurately obtain the lifespan data of the buttons on the meat grinder 700.

[0095] During this process, the first elastic element primarily provides cushioning when the pressure shaft 453 contacts and applies pressure to the button of the meat grinder 700, preventing the pressure shaft 453 from causing rigid impact to the button and damaging it. Simultaneously, the elastic force of the first elastic element can simulate the force changes when a human hand presses the button, making the test results closer to actual usage. The first elastic element can be configured with components with good elasticity, such as springs, and its elastic coefficient can be selected and adjusted according to actual testing needs to ensure accurate detection of the performance of the meat grinder 700 button under different forces; no restrictions are imposed here.

[0096] Please see Figure 9 and Figure 11In one embodiment, the high-pressure needle structure 470 includes a high-pressure instrument, a first conductive needle body 471, a first conductive buffer pad 472, a second conductive needle body 473, and a second conductive buffer pad 474. The first conductive needle body 471 is movably disposed on the base and is electrically connected to the high-pressure instrument. The first conductive needle body 471 can approach the meat grinder 700 and contact the metal shell of the meat grinder 700. The first conductive buffer pad 472 is disposed at the end of the first conductive needle body 471 that contacts the metal shell of the meat grinder 700. The second conductive needle body 473 is movably disposed on the base and is electrically connected to the high-pressure instrument. The first conductive needle body 471 can approach the plug 710 and contact the plug 710. The second conductive buffer pad 474 is disposed at the end of the second conductive needle body 473 that contacts the plug 710 of the meat grinder 700. The first conductive buffer pad 472 and the second conductive buffer pad 474 can be configured as materials with good conductivity and buffering properties, such as conductive metal foam or conductive rubber, to effectively buffer the impact force between the first conductive needle 471 and the metal shell of the meat grinder 700, and between the second conductive needle 473 and the plug 710 of the meat grinder 700, while ensuring conductivity. The first conductive needle 471 and the second conductive needle 473 can be configured as components with good conductivity, such as metal probes, without limitation. Specifically, a test position is reserved on the outer wall of the plug 710, and a metal test piece connected to the internal grounding wire of the plug 710 is provided at the test position. The metal test piece is embedded in the insulating shell of the plug 710, and the second conductive buffer pad 474 can contact the metal test piece. The first conductive needle 471 and the second conductive needle 473 are respectively mounted on the worktable via a third mounting base 477 and a fifth driving structure 478. The fifth driving structure 478 can drive the corresponding third mounting base 477 to move the first conductive needle 471 closer to or away from the metal casing of the meat grinder 700. The other fifth driving structure 478 can drive the corresponding third mounting base 477 to move the second conductive needle closer to or away from the test position of the plug 710. The fifth driving structure 478 can be configured as a linear module or other structures; no limitation is made here.

[0097] When performing an insulation test, the power-on structure 410 resets to disconnect the power supply to the meat grinder 700. The two fifth drive structures 478 respectively drive the first conductive needle 471 to approach the metal shell of the meat grinder 700 and the second conductive needle 473 to approach the test position of the plug 710, until the first conductive buffer pad 472 is in close contact with the metal shell and the second conductive buffer pad 474 is in reliable contact with the metal test piece. The high voltage instrument starts and outputs a high voltage signal. The high voltage signal passes sequentially through the high voltage end of the high voltage instrument, the first conductive needle 471, the first conductive buffer pad 472, the metal shell of the meat grinder 700, the metal test piece of the plug 710, the second conductive buffer pad 474, and the second conductive needle 473, and finally returns to the circuit end of the high voltage instrument, forming a complete test circuit. The high-voltage tester's detection module can detect the magnitude of the current in the circuit and transmit the detection results to the control system. If the detected current value is within the preset safety threshold range, it indicates that the meat grinder 700 has good insulation performance. If the detected current value exceeds the preset safety threshold range, it indicates that the meat grinder 700 has insulation problems such as leakage. The control system will promptly record the unqualified product and alert the staff through alarms and other means.

[0098] Furthermore, a second elastic element 475 is sleeved around the outer periphery of the first conductive needle body 471, and a third elastic element 476 is sleeved around the outer periphery of the second conductive needle body 473. One end of the first conductive needle body 471 connected to the second conductive buffer sheet has a stop protrusion on its outer periphery, and the other end movably passes through a corresponding third mounting base 477. The opposite ends of the second elastic element 475 abut against the stop protrusion and the third mounting base 477 respectively, to further buffer the impact force between the first conductive needle body 471 and the metal shell of the meat grinder 700, preventing a rigid collision between the first conductive needle body 471 and the metal shell. Simultaneously, the elastic force of the second elastic element 475 ensures a stable and good contact between the first conductive needle body 471 and the metal shell, guaranteeing the accuracy of the insulation test. The structure of the second conductive needle body 473 can be referenced to the structure of the first conductive needle body 471, and the function of the third elastic element 476 can be referenced to the function of the second elastic element 475, which will not be elaborated further here. The second elastic element 475 and the third elastic element 476 can both be configured as springs or silicone sleeves or other materials with good elasticity, and no restrictions are imposed here.

[0099] Please see Figure 9 and Figure 12In one embodiment, the rotation speed testing structure 460 includes a rotation unit and a main testing unit. The rotation unit includes a second mechanical claw structure 461 and a torque sensor 462. The main testing unit includes a test shaft 464, an encoder 463, a fifth mounting base 465, and a sixth drive structure 466. The rotation unit is used to rotate the knob 720 of the meat grinder 700 to adjust the gear. The second mechanical claw structure 461 is mounted on the base and can be configured similarly to the first mechanical claw structure 430, which will not be described in detail here. The torque sensor 462 is mounted on the mechanical claw body 431 of the second mechanical claw structure 461 and is coaxially arranged with the mechanical claw body 431 to detect the magnitude of the torque received by the second mechanical claw structure 461 when rotating the knob 720 of the meat grinder 700. The main testing unit is used to test the rotational speed of the meat grinder 700 at different speeds. The sixth drive structure 466 is mounted on the worktable and driven by the fifth mounting base 465. The test shaft 464 is rotatably mounted on the fifth mounting base 465. The encoder 463 is mounted on the fifth mounting base 465 and connected to one end of the test shaft 464. The other end of the test shaft 464 can extend into the grinding drum 730 of the meat grinder 700 and engage with the rotor hole. Specifically, the end of the test shaft 464 away from the encoder 463 has a engaging part. The shape and size of the engaging part can be flexibly set according to the shape and size of the rotor hole to ensure that the test shaft 464 can rotate synchronously with the rotor hole. The sixth drive structure 466 can be configured as a motor or a linear module, etc.; the encoder 463 can be configured as a photoelectric encoder 463 or a magnetoelectric single-turn encoder 463, etc.; the torque sensor 462 can be configured as a flange static torque sensor 462, etc., without limitation.

[0100] When speed testing is required, the control system first controls the sixth drive structure 466 to drive the test shaft 464 into the rotor hole. Then, it controls the rotation unit to move so that the second mechanical gripper structure 461 clamps and rotates the knob 720 of the meat grinder 700. This causes the rotor hole of the meat grinder 700 to drive the test shaft 464 to rotate. The encoder 463 outputs a real-time pulse sequence to the control system, which can convert the real-time pulse sequence into instantaneous speed. The second mechanical gripper structure 461 can rotate the knob 720 to different positions, allowing the encoder 463 to output corresponding real-time pulse sequences based on the rotation of the test shaft 464 at different positions. This enables the control system to accurately calculate the actual speed of the meat grinder 700 at different positions. During speed testing, the torque sensor 462 detects the torque received by the second mechanical gripper structure 461 when rotating the knob 720 in real time and transmits the data to the control system. The control system can then integrate the speed data and torque data to comprehensively evaluate the rotational performance of the meat grinder 700 at different positions.

[0101] Please see Figure 7 , Figure 9 , Figure 13 and Figure 14 In one embodiment, the conveying assembly 100 includes a first conveying structure 110 and a second conveying structure 120 that is vertically mounted on the conveying path of the first conveying structure 110. The conveying direction of the second conveying structure 120 is perpendicular to the conveying direction of the first conveying structure 110. The testing assembly 400 also includes a receiving structure that is movably mounted on the base and whose conveying direction is the same as that of the second conveying structure 120. The second conveying structure 120 is capable of conveying the fixture to the receiving structure.

[0102] The first conveying structure 110 includes a conveying chain 112, a seventh drive structure, and two parallel and spaced fixed frames 111. A conveying chain 112 is movably mounted on each fixed frame 111. The fixture's support plate 210 is mounted on the two conveying chains 112. The seventh drive structure is located on the fixed frames 111 and is driven by the two conveying chains 112 to move the fixture. The seventh drive structure can be configured as a motor and gear transmission structure, etc., and is not limited here. The two fixed frames 111 are interconnected, and there is a gap between them to accommodate the second conveying structure 120. Each test structure is provided with a corresponding second conveying structure 120. The second conveying structure 120 includes a sixth mounting base 121, a first conveyor belt 122, and an eighth drive structure. The sixth mounting base 121 is located between two fixed frames 111. The eighth drive structure includes a first power component 123 and a second power component 124. The first power component 123 is drivenly connected to the first conveyor belt 122 to drive the first conveyor belt 122 to rotate relative to the sixth mounting base 121. The second power component 124 is located on the sixth mounting base 121 and drivenly connected to the first power component 123 to drive the first power component 123 to lift the first conveyor belt 122. The first power component 123 can be configured as a swing cylinder or a rotary motor, etc., and is drivenly connected to the first conveyor belt 122 through a synchronous pulley structure. The second power component 124 can be configured as a linear motor or a feed cylinder, etc., without limitation. Furthermore, the conveying assembly 100 also includes a loading belt 130 and a unloading belt 140, which are located at opposite ends of the conveying chain 112 to perform loading and unloading operations on the fixture.

[0103] Each workstation is equipped with a receiving structure. The straight-line distance between the receiving structure and the second conveying structure 120 is less than that of the gear on the pallet 210, ensuring that the pallet 210 can be smoothly conveyed between the second conveying structure 120 and the receiving structure. The receiving structure includes a support frame 481, a second conveyor belt 482, and a ninth drive structure 483. Two support frames 481 are arranged in parallel and spaced apart, and each support frame 481 is movably connected to a second conveyor belt 482. The ninth drive structure 483 includes a third power component and a synchronous pulley. The third power component is located on the worktable and drives the second conveyor belt 482 to rotate through the synchronous pulley. Specifically, the two synchronous pulleys connected to the two second conveyor belts 482 are connected by a connecting rod. A first bevel gear is sleeved on the outer circumference of the connecting rod, and a second bevel gear is sleeved on the outer circumference of the output shaft of the third power component. The first bevel gear and the second bevel gear mesh with each other. When the output shaft of the third power component rotates, it can drive the connecting rod to rotate synchronously through the transmission of the first bevel gear and the second bevel gear, thereby causing the two second conveyor belts 482 to rotate synchronously. The third power component can be configured as a swing cylinder or a rotary motor, etc., without limitation. In one embodiment, the receiving structure also includes a limiting component, which is located on the support frame 481 away from the second conveying structure 120, and is used to abut against the pallet 210 to prevent the pallet 210 from detaching from the second conveyor belt 482. The first limiting component can be configured as a baffle or a limiting roller, etc., without limitation.

[0104] Please see Figure 7 and Figure 9 In one embodiment, the test assembly 400 further includes a lifting structure surrounding the receiving structure. Each working position has a lifting structure, which includes a carrier plate 491 and a fourth power member 492. The carrier plate 491 is located near the second conveyor belt 482 and is drivenly connected to the fourth power member 492. The gap between the two conveyor belts is smaller than the size of the pallet 210. When the pallet 210 is located on the second conveyor belt 482, the fourth power member 492 can drive the carrier plate 491 to rise and lift the pallet 210 off the second conveyor belt 482, so that the pallet 210 is stably placed on the carrier plate 491, so that the test structure can perform various performance tests on the meat grinder 700 placed on the pallet 210.

[0105] Please see Figure 7 In one embodiment, the test line of the meat grinder 700 further includes a transition structure, which includes a positioning bracket 510 and a transition roller 520. The positioning bracket 510 is disposed on the workbench and located between the first conveyor belt 122 and the second conveyor belt 482. The transition roller 520 is rotatably disposed on the positioning bracket 510 and can provide support for the fixture when the fixture moves between the first conveyor belt 122 and the second conveyor belt 482, so that the fixture can smoothly transition from the first conveyor belt 122 to the second conveyor belt 482, ensuring the continuity and stability of the conveying process.

[0106] Please see Figure 7 In one embodiment, the test line of the meat grinder 700 further includes a first barcode scanner 310, located between two support frames 481. A barcode scanner 211 is provided at the bottom of the tray 210. When the meat grinder 700 is placed on the tray 210 and the fixture reaches the working position, the bottom markings or QR codes of the meat grinder 700 can be read by the first barcode scanner 310 through the barcode scanner 211. The first barcode scanner 310 is electrically connected to the control system and can transmit the read markings or QR code information to the control system in real time. The control system identifies and records the meat grinder 700 based on the received information, providing accurate basis for subsequent test data association and traceability, realizing information management of the testing process, and improving testing efficiency and data accuracy. Further, please refer to... Figure 13 The testing line for the meat grinder 700 also includes a second barcode scanner 320, which is located between two fixed frames 111. During the process of conveying the fixture carrying the meat grinder 700 via the first conveying structure 110, the second barcode scanner 320 reads the bottom markings or QR codes of the meat grinder 700 through the detection port of the pallet 210. The reading information from the first barcode scanner 310 and the second barcode scanner 320 complement each other, further ensuring the accuracy of traceability.

[0107] When the meat grinder 700 needs to be inspected, the control system controls the seventh drive structure to drive the conveyor chain 112 to move the fixture carrying the meat grinder 700 above the second conveyor structure 120. Then, the control system controls the second power component 124 to drive the first power component 123 to drive the first conveyor belt 122 to rise, so that the first conveyor belt 122 contacts the bottom of the fixture and lifts the fixture. Subsequently, the control system controls the first power component 123 to drive the first conveyor belt 122 to rotate and controls the ninth drive structure 483 to drive the second conveyor belt 482 to rotate, so that... The fixture is smoothly conveyed to the working position under the joint transmission of the first conveyor belt 122 and the second conveyor belt 482. When the fixture completely leaves the first conveyor belt 122 and is located entirely on the second conveyor belt 482, the first power component 123 and the ninth drive structure 483 stop working. The control system then controls the fourth power component 492 to drive the carrier plate 491 to rise, so as to lift the fixture and make the fixture in a stable state, ensuring the stability of the fixture during the test. At the same time, the control system controls the corresponding test structure to work to test the meat grinder 700.

[0108] After the test is completed, the control system controls the lifting structure to reset; then, it controls the receiving structure and the second conveying structure 120 to work to send the fixture back to the second conveying structure 120; after the fixture is located in the second conveying structure 120, the control system controls the second conveying structure 120 to reset, and at the same time controls the first conveying structure 110 to work to transport the fixture to the next second conveying structure 120 for the next round of testing.

[0109] Please see Figure 14 and Figure 15 In one embodiment, the test line of the meat grinder 700 further includes a first positioning detection element 610, a limiting block 620, a support roller 630, and a drive member 640. The first positioning detection element 610 is disposed on the base and opposite to the second conveying structure 120, and is used to detect whether the fixture has reached the second conveying structure 120. The limiting block 620 is configured as a triangular structure with a first end, a second end, and a third end 621 arranged circumferentially. The first end is rotatably connected to the base. The support roller 630 is rotatably disposed on the second end and can contact the bottom surface of the tray 210 and roll along the tray 210. The drive member 640 is disposed on the base and is drivenly connected to the third end 621, and can drive the third end 621 to drive the second end to rotate around the first end, so that the third end 621 abuts against the side of the tray 210 or the support roller 630 contacts the bottom surface of the tray 210, so as to limit or release the fixture in the second conveying structure 120.

[0110] The limiting block 620 is mounted on the base via a seventh mounting base 650. The seventh mounting base 650 is located between two fixed frames 111 and is rotatably connected to the first end of the limiting block 620 via a rotating shaft. The driving member 640 is mounted on the seventh mounting base 650 and is drivenly connected to the third end 621. The third end 621 has a second groove on the side facing the output shaft of the driving member 640, and the output shaft of the driving member 640 extends movably into the second groove to drively connect with the third end 621. The driving member 640 can be configured as a motor or cylinder, etc., and is not limited here.

[0111] The first positioning detection element 610 is configured as a through-beam detection structure, including a transmitter and a receiver. The transmitter and receiver are respectively disposed on a fixed frame 111 and located on opposite sides of the second conveying structure 120. The line connecting the transmitter and receiver is inclined relative to the conveying direction of the first conveying structure 110 to more accurately detect whether the fixture has reached the second conveying structure 120. When the fixture moves above the second conveying structure 120 and blocks the light emitted by the transmitter, the receiver cannot receive the signal and will send a signal to the control system that the fixture has reached the position. After receiving the signal, the control system will immediately control the first conveying structure 110 to stop, ensuring that the fixture stops accurately above the second conveying structure 120; at the same time, it will control the drive 640 to drive the third end 621 of the limiting block 620 to rotate the second end around the first end, so that the third end 621 is higher than the second end and abuts against the side of the support plate 210, limiting the fixture and further preventing the fixture from being misaligned relative to the second conveying structure 120. When the first conveying structure 110 is required to normally convey the fixture, the driving member 640 drives the third end 621 to rotate the second end around the first end, so that the third end 621 is lower than the second end, avoiding the third end 621 from obstructing the pallet 210. At the same time, the supporting roller 630 contacts the bottom surface of the pallet 210 and can roll along the bottom surface of the pallet 210 to provide stable support for the conveying of the fixture. Multiple sets of the first positioning detection element 610 can be provided to detect the position of the fixture in the first conveying result in real time. Of course, in other embodiments, the first positioning detection element 610 can also be configured as a proximity switch or a vision detection structure, etc., and there is no limitation here.
