Description

Technical Field

[0001] The present invention relates to the technical field of coffee machine detection, and particularly to an automatic test platform for coffee machine production quality control management. Background Art

[0002] A coffee machine is an electrical device that combines water and coffee powder through an automated or semi-automated process to produce different types of coffee. The coffee machine intelligently controls the water temperature, pressure, and extraction time, allowing users to easily make professional-grade coffee at home or in a commercial setting.

[0003] During the production process of a coffee machine, a water pump needs to be connected to an extraction boiler through a three-way valve, and there also needs to be a pipeline connection between the extraction boiler and the brewing head. Since the extraction boiler needs to maintain a sealed state with a stable pressure during the use of the coffee machine, it is necessary to ensure the overall sealing of the extraction boiler, as well as the sealing of each inlet and outlet pipeline and the pipeline connection parts. Currently, the sealing of different parts is detected one by one, resulting in low detection efficiency. During the detection process of the position change of different parts, it is also easy to cause inaccurate detection. In addition, during the use of the coffee machine, the internal pump components will generate a certain amount of vibration, and the finished coffee machine is also prone to being jolted during transportation. These will all have a certain impact on the sealing of each part of the coffee machine. Therefore, an automatic test platform for coffee machine production quality control management is proposed.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Example, refer to Figures 1 to 10 , an automatic test platform for quality control management of coffee machine production, including a test base 1 and a simulation platform 2 for installing coffee machine components 3. A plurality of fixed seats 4 are connected to the top end of the test base 1. A plurality of flexible spring rods 5 are connected to the fixed seats 4. The end of the flexible spring rod 5 is fixedly connected to a fixing plate 6. The end face of the fixing plate 6 is connected to a transfer plate 12 through a compensation component. Electromagnetic limit columns 10 are connected to both sides of the fixing plate 6 through connecting plates. An electric control guide rail 13 is connected to the outside of the transfer plate 12. The inner side walls of the electric control guide rail 13 are respectively connected to a detection half cover 17 through two sliding seats 14;

[0036] Furthermore, the compensation component is composed of a compensation telescopic rod 7, a universal bead 8, and a spherical tile 9. The fixing plate 6 is fixedly connected to the universal bead 8 through the compensation telescopic rod 7. The universal bead 8 is rotatably connected to the inner side wall of the spherical tile 9. The outer side wall of the spherical tile 9 is fixedly connected to the outside of the transfer plate 12. Two opposite limiting magnetic beads 11 are fixedly connected to the outside of the transfer plate 12. The limiting magnetic beads 11 are opposite to the positions of the electromagnetic limit columns 10. The inner side wall of the electric control guide rail 13 is slidably connected to the sliding seat 14. Two opposite docking plates 15 are fixedly connected to the outer side wall of the detection half cover 17. Two docking magnetic seats 16 are fixedly connected to the inward side wall of the docking plate 15. The end of the sliding seat 14 is fixedly connected to one side of the docking plate 15 through a right-angle rod. An arc-shaped sealing hopper 18 is connected to the bottom end of the detection half cover 17. A pipe-shaped sealing hopper 20 is connected to the top end of the detection half cover 17. Sealing rubber strips 19 are fixedly connected to both side walls of the detection half cover 17. A port sealing cover 40 is fixedly connected to the top end of the pipe-shaped sealing hopper 20. A pressure sensor 22 is connected to one side of the detection half cover 17;

[0037] It should be noted that: the base of the coffee machine component 3 with the sealed component assembled is fixedly installed on the simulation platform 2. Subsequently, the flexible spring rod 5 on the fixed seat 4 is bent to the sealed parts at the pipeline ports or connection parts such as the extraction boiler and the three-way valve on the coffee machine component 3. Then, the two detection half covers 17 are placed on both sides of the part to be detected. Then, the two sliding seats 14 slide towards each other in the electric control guide rail 13, so as to drive the two detection half covers 17 to approach each other, making the two docking magnetic seats 16 on the opposite docking plates 15 magnetically attract each other, and making the sealing rubber strips 19 on the two detection half covers 17 press against each other, so that the opposite arc-shaped sealing hoppers 18, pipe surface sealing hoppers 20 and port sealing covers 40 are butted and pressed against each other (wherein the arc-shaped sealing hoppers 18, pipe surface sealing hoppers 20 and port sealing covers 40 are all made of rubber). When detecting the pipeline connection part, the port sealing cover 40 is turned outwards, and the pipe surface sealing hopper 20 is pressed against the outer side wall of the pipeline. At the same time, through a plurality of obliquely arranged electric control suction cups 21 adsorbed on the arc-shaped surfaces such as the boiler, the arc-shaped sealing hopper 18 can be pressed for sealing. Then, the overall sealed component is gradually pressurized. This is a commonly used technical means for detection and will not be elaborated here. If there is insufficient sealing in each sealed part, the gas inside the coffee machine will gradually leak out, resulting in the gradual increase of the air pressure in the space formed by the two detection half covers 17, which can then be detected and recognized by the air pressure sensor 22;

[0038] Based on the above advantages: in this way, multiple detection half covers 17 can be used to uniformly test the sealing performance of each sealed part of the coffee machine component 3, and quickly identify where there are unqualified sealing performances, greatly improving the overall detection efficiency, and also avoiding the mutual influence during the separate detection of different parts, making the detection results more accurate and reliable;

[0039] A plurality of electric control suction cups 21 are connected to the outer side wall of the detection half cover 17 through a fixed half ring, and two temperature measuring components for testing the temperature of the pipeline are connected to the outer side wall of the fixed half ring;

[0040] Furthermore, the temperature measuring component is composed of a thermometer 24 and a heat conduction arc plate 25. The fixed half ring is fixedly connected to the thermometer 24 through a spring bent rod 23, and the temperature measuring part of the thermometer 24 is connected to the heat conduction arc plate 25;

[0041] It should be noted that: while performing the sealing detection, the spring bent rod 23 is bent on both sides of the extraction pipeline or the extraction boiler, and the opposite heat conduction arc plates 25 are pressed against the outer side walls of the same material. Then, the heating module is started (this is the structure of an existing coffee machine) to simulate the temperature state when using the coffee machine component 3 to extract coffee;

[0042] The benefits based on the above are as follows: The thermometer 24 will measure the temperatures of boilers or pipelines made of the same material at different positions through the heat-conducting arc plate 25, avoiding insufficient power of the coffee machine heating block or failure of the temperature control module, and ensuring that the water temperature will not fluctuate significantly during the use of the coffee machine;

[0043] Two limiting components for limiting the simulation platform 2 are respectively connected to the top end of the test base 1. The two sides of each limiting component are provided with piston rods 31. The piston rods 31 are connected to a main oil pipe 33 through piston plates 32. The two sides of the main oil pipe 33 are respectively provided with branch oil pipes 34. A valve assembly is arranged below the piston plate 32. The outer side wall of the branch oil pipe 34 is connected to a protective pipe shell 35;

[0044] Further, the limiting component consists of an insertion plate 28 and a threaded rod 27. A limiting groove adapted to the insertion plate 28 is opened at the bottom end of the simulation platform 2. A through hole is opened on the insertion plate 28. A limiting rod is slidably connected to the through hole. The top end of the test base 1 is rotatably connected to a threaded sleeve 26. The threaded sleeve 26 is threadedly connected to the threaded rod 27. The limiting rod is fixedly connected to the top end of the test base 1. A support seat 29 is fixedly connected to the bottom end of the simulation platform 2. The support seat 29 is fixedly connected to a rubber adapter sleeve 30 through a support rod. The large port of the rubber adapter sleeve 30 is fixedly connected to the top end of the piston rod 31. The bottom end of the piston rod 31 is fixedly connected to the top end of the piston plate 32. The side wall of the piston plate 32 is slidably connected to the inner side wall of the main oil pipe 33. The outer side wall of the piston rod 31 is slidably connected to the inner side wall of the circular hole opened at the top end of the protective pipe shell 35. The outer side wall of the branch oil pipe 34 is fixedly connected to the inner side wall of the protective pipe shell 35. The lower ports of the two branch oil pipes 34 are fixedly connected to the main oil pipe 33 through oil pipe connectors 38. The upper ports of the branch oil pipes 34 are in a sealed state. The valve assembly consists of a limiting plate 36, a buffer spring 37 and a valve plate 39. The bottom end of the limiting plate 36 is fixedly connected to the inner top side wall of the main oil pipe 33 through a sliding rod. The buffer spring 37 is sleeved on the outer side wall of the sliding rod. The valve plate 39 is slidably connected to the outer side wall of the sliding rod;

[0045] It should be noted that: Before the simulation of the bumps during the transportation of the coffee machine or the vibrations during use, first cut off the power supply of the electromagnetic limit post 10, so that the magnetic attraction limit between the electromagnetic limit post 10 and the limit magnetic bead 11 is released, allowing the compensation telescopic rod 7 to cooperate with the free rotation of the universal beads 8 to compensate for the displacement and angle between the detection half cover 17 and the flexible spring rod 5 during the subsequent simulation of vibrations, avoiding the detection half cover 17 being pulled off. Subsequently, control the rotation of the threaded sleeve 26 to make the threaded rod 27 move downward during rotation, so that the insertion plate 28 moves downward and disengages from the limiting groove, canceling the fixed limit on the simulation platform 2;

[0046] During the vibration simulation process, the staff applies a vibration external force to the simulation platform 2. At this time, the piston rod 31 will drive the piston plate 32 to slide on the inner wall of the main oil pipe 33, compressing and pumping the oil column in the main oil pipe 33 to ensure that the hydraulic oil in the main oil pipe 33 is full. When the oil column in the main oil pipe 33 is compressed downward, the hydraulic oil will be pressed into the two branch oil pipes 34 through the gap between the valve plate 39 and the oil pipe interface 38. When the oil column in the main oil pipe 33 moves upward, it will drive the valve plate 39 to compress the buffer spring 37 and slide upward, quickly pumping the hydraulic oil in the two branch oil pipes 34, realizing the slow vibration simulation of up and down bumps (simulating the state with shock absorption after overall assembly or when installed at home, making the vibration simulation state more in line with the actual use situation). For the lateral vibration, the air in the rubber adapter sleeve 30 is in a state of continuous compression and expansion slowdown for actual simulation, and then the sealing condition of the overall coffee machine component 3 is detected in this state;

[0047] The benefits based on the above are as follows: This can utilize the air pumping and pressure in the rubber adapter sleeve 30 and the hydraulic buffer in the main oil pipe 33 to simulate a vibration mode with a certain shock absorption buffer state, simulating the vibration environment of the coffee machine component 3 during use, being more in line with the state with a certain shock absorption after overall assembly and after installation and use, making the coffee machine detection in this state more in line with the actual use situation and ensuring that the detection results are more scientific and reliable;

[0048] When the present invention is in use, the base of the coffee machine component 3 with the sealing component assembled is fixedly installed on the simulation platform 2. Subsequently, the flexible spring rod 5 on the fixed seat 4 is bent to the sealing position of the pipeline ports or connection parts such as the extraction boiler and the three-way valve on the coffee machine component 3. Then, the two detection half covers 17 are placed on both sides of the part to be detected. Then, the two sliding seats 14 slide towards each other in the electric control guide rail 13, so as to drive the two detection half covers 17 to approach each other, making the two docking magnetic seats 16 on the two opposite docking plates 15 magnetically attract each other, and making the sealing rubber strips 19 on the two detection half covers 17 press against each other, so that the opposite arc surface sealing hoppers 18, pipe surface sealing hoppers 20 and port sealing covers 40 are docked and pressed against each other (where the arc surface sealing hoppers 18, pipe surface sealing hoppers 20 and port sealing covers 40 are all made of rubber). When detecting the pipeline connection part, the port sealing cover 40 is turned outwards, and the pipe surface sealing hopper 20 is pressed against the outer side wall of the pipeline. At the same time, the electric control suction cups 21 arranged obliquely are adsorbed on the arc-shaped surfaces such as the boiler, so that the arc surface sealing hopper 18 can be pressed and sealed. Subsequently, the overall sealing component is gradually pressurized. This is a commonly used technical means for detection and will not be elaborated here. If there is insufficient sealing in each sealing part, the gas inside the coffee machine will gradually leak out, resulting in an increase in the air pressure in the space formed by the two detection half covers 17, which can then be detected and recognized by the air pressure sensor 22. In this way, the sealing performance of each sealing part of the coffee machine component 3 can be uniformly tested by using multiple detection half covers 17, and the location where the sealing performance is unqualified can be quickly identified, greatly improving the overall detection efficiency and avoiding the mutual influence during the separate detection of different parts, making the detection result more accurate and reliable;

[0049] While performing the sealing detection, the spring bent rod 23 is bent on both sides of the extraction pipeline or the extraction boiler, and the opposite heat conducting arc plates 25 are pressed against the outer side wall of the same material. Then, the heating module (this is the structure of an existing coffee machine) is started to simulate the temperature state when using the coffee machine component 3 to extract coffee. Then, the thermometer 24 will measure the temperature conditions of the boiler or pipeline of the same material at different parts through the heat conducting arc plates 25, avoiding insufficient power of the coffee machine heating block or failure of the temperature control module, and ensuring that the water temperature will not be too high or too low during the use of the coffee machine;

[0050] Before simulating the bumps during the transportation of the coffee machine or the vibrations during use, first cut off the power supply of the electromagnetic limit post 10, so that the magnetic attraction limit between the electromagnetic limit post 10 and the limit magnetic bead 11 is released, and the compensation telescopic rod 7 cooperates with the free rotation of the universal beads 8 to compensate for the displacement and angle between the detection half cover 17 and the flexible spring rod 5 during the subsequent simulated vibration process, avoiding the detection half cover 17 being pulled off. Then, control the rotation of the threaded sleeve 26, and the threaded rod 27 moves downward during rotation, so that the insertion plate 28 moves downward and disengages from the limit slot, canceling the fixed limit of the simulation platform 2;

[0051] During the vibration simulation process, the vibration external force applied by the staff to the simulation platform 2 causes the piston rod 31 to drive the piston plate 32 to slide on the inner wall of the main oil pipe 33, compressing and pumping the oil column in the main oil pipe 33 to ensure that the hydraulic oil in the main oil pipe 33 is full. When the oil column in the main oil pipe 33 is compressed downward, the hydraulic oil will be pressed into the two branch oil pipes 34 through the gap between the valve plate 39 and the oil pipe interface 38. When the oil column in the main oil pipe 33 moves upward, it will drive the valve plate 39 to compress the buffer spring 37 and slide upward, quickly pumping the hydraulic oil in the two branch oil pipes 34, realizing the slow vibration simulation of the up and down bumps (simulating the state with shock absorption when assembled or installed at home, making the vibration simulation state more in line with the actual use situation). For the lateral vibration, the air in the rubber adapter sleeve 30 is in a state of continuous compression and expansion slowdown for actual simulation. Then, the sealing performance of the overall coffee machine component 3 is detected in this state. In this way, the air suction and pressure in the rubber adapter sleeve 30 and the hydraulic buffer in the main oil pipe 33 can be used to simulate a vibration mode with a certain shock absorption and buffer state, simulating the vibration environment of the coffee machine component 3 during use, which is more in line with the state with a certain shock absorption after overall assembly and installation, making the coffee machine detection in this state more in line with the actual use situation and ensuring that the detection results are more scientific and reliable.
