Description

Technical Field

[0001] This invention relates to the field of meat product testing technology, and in particular to an online meat product testing component and a liquid nitrogen quick-freezing cabinet. Background Technology

[0002] In the field of food processing and safety testing, frozen storage is a crucial step in ensuring meat quality and extending shelf life. The quality characteristics of meat during the freezing process directly affect its tissue structure, nutrient retention, and subsequent safety for consumption. For testing centers, accurately grasping the parameter information of different meats during the freezing process is an important prerequisite for conducting subsequent frozen meat quality testing, microbial content analysis, and physicochemical index evaluation. The scientific validity and reliability of the test results highly depend on the precise control of the freezing process parameters.

[0003] Currently, meat freezing primarily utilizes conventional freezing equipment such as cold storage facilities and blast freezers. These devices only provide basic low-temperature freezing and cannot monitor and record key parameters during the freezing process in real-time and intuitively. In actual testing, to obtain quality characteristic parameters of frozen meat, testing personnel typically use offline sampling, where meat samples are taken at specific points in the freezing process and analyzed using specialized instruments. However, this method has several drawbacks: firstly, sampling is destructive, meaning some samples cannot be used for subsequent comprehensive testing, resulting in sample waste; secondly, offline testing cannot continuously track parameter changes throughout the entire freezing process, only obtaining discrete time-point data, which is insufficient to fully reflect the dynamic changes during freezing, potentially leading to biased judgments of quality characteristics and affecting the accuracy of subsequent test results.

[0004] Therefore, given the technological gap in existing freezing equipment's inability to intuitively and in real-time monitor the quality characteristics of meat during the freezing process, thus affecting subsequent testing, developing a specialized device capable of accurately monitoring the quality characteristics of different meats during the freezing process and assisting in subsequent inspection and testing has become an urgent technical problem to be solved in the current food testing field. Summary of the Invention

[0005] The purpose of this invention is to provide an online meat inspection component and a liquid nitrogen quick-freezing cabinet, which solves the problem mentioned in the background art that existing freezing equipment cannot intuitively and in real time monitor the quality of meat during the freezing process.

[0006] The technical solution adopted in this invention is as follows: An online meat product detection component includes a rectangular frame, which is welded together from end to end to form first square tubes. Two sets of first wheel seats are symmetrically arranged on the bottom surface of the rectangular frame, and first rollers are rotatably connected to the first wheel seats. Four second square tubes are symmetrically arranged on the top surface of the rectangular frame, and the upper sidewalls of the four second square tubes are connected in series via third square tubes. Support plates are connected to the sidewalls of the second square tubes at equal intervals from top to bottom. The four support plates form a frame structure, on which a material tray is placed, and meat products are placed inside the material tray. First wire holes are opened on the sidewalls of the two front second square tubes, and each second square tube has at least three first wire holes (top, middle, and bottom). Foot seats are fixed to the sidewalls of the second square tubes by bolts. Each foot seat has a second wire hole communicating with the first wire holes. A first conduit is connected, with a central column connected to its free end. A second conduit is connected at the angle of the first conduit, and a first tube seat is connected to the side wall of the second conduit. A sensor assembly is connected to the lower end of the first tube seat. The sensor assembly is used for online detection of parameters of meat products. The wiring of the sensor assembly passes through the second conduit, the first conduit, the foot seat, and the second square tube. A positioning tube is installed at the upper end of the second square tube located at the front. Two symmetrically arranged first limiting plates are connected to the inner wall of the positioning tube. A flap is hinged to the top surface of the first limiting plate. When the flaps on both sides are in a horizontal state, they can close the positioning tube to block moisture. A first spring is connected to the bottom surface of the flap, and the free end of the first spring is connected to the inner wall of the positioning tube. A socket is connected to the end of the sensor assembly, and the socket is located below the flap. An insulation component is provided on the outer wall of the sensor assembly wiring.

[0007] A liquid nitrogen quick-freezing cabinet using the aforementioned online meat detection component includes a cabinet body with a door connected to the front side of the cabinet body via hinges. The door is fixed to the cabinet body by a wheel handle lock. Two symmetrical first tracks are mounted on the bottom surface of the cabinet body, with first guide grooves on the top surface of the first tracks, and first rollers roll along the first guide grooves. A U-shaped adjusting seat is mounted on the bottom surface of the cabinet body, and a second limiting plate for blocking a rectangular frame is fixed to the adjusting seat by positioning bolts. A first partition is installed inside the cabinet body, dividing the interior into a quick-freezing chamber and a circulation chamber. A liquid nitrogen pipe is installed in the quick-freezing chamber, and an atomizing nozzle is installed on the liquid nitrogen pipe. Four equidistant second partitions are installed in the circulation chamber, dividing the circulation chamber into four independent chambers. An air inlet is opened on the upper side wall of each of the first partitions, and four air outlets are arranged from top to bottom and corresponding to the independent chambers, with exhaust fans installed on the air outlets. A plug assembly compatible with a socket is mounted on the top surface of the cabinet body.

[0008] Inside the cabinet, there are two symmetrically arranged second bearing seats that are rotatably connected. A main pipe is rotatably connected to the second bearing seats. A valve body with a plug is installed in the middle of the main pipe. One end of the valve body is connected to a branch pipe, and the free end of the branch pipe is connected to a liquid nitrogen pipe. An atomizing nozzle is installed on the liquid nitrogen pipe. The other end of the valve body is connected to an overflow valve. An auxiliary support is connected between the main pipe and the liquid nitrogen pipe. A gear set is connected to the main pipe outside the cabinet. The gear set is driven by a third motor.

[0009] The beneficial effects of this invention are as follows: The technical advantages of this invention are reflected in two aspects: the online meat detection component and the matching liquid nitrogen quick-freezing cabinet. Specifically, the structural design of the online meat detection component has multiple advantages. The combination of the rectangular frame, the first wheel seat, and the first roller enables convenient movement and stable support of the component; the frame structure composed of the support plate ensures that the trays are placed neatly; the first and second conduits allow for orderly wiring; the cooperation between the flap inside the positioning tube and the first spring effectively blocks moisture; and the insulation component provides insulation and moisture protection for the wiring. The two different sensor components achieve convenient plugging and unplugging of the fiber optic probe and rapid buffered plugging and unplugging, respectively. Combined with the detection system composed of the processor, near-infrared spectrometer, and fiber optic converter, it can realize rapid and non-destructive online detection of quality characteristic parameters of meat products during the freezing process. This avoids the sample waste of traditional sampling detection and solves the defect that offline detection cannot continuously track dynamic changes, greatly improving the accuracy and reliability of detection. Secondly, the liquid nitrogen quick-freezing cabinet using this component also boasts excellent performance. The first track and second limiting plate enable precise positioning and movement of the detection components; the first and second partitions, in conjunction with the exhaust fan, create four independent nitrogen circulations, resulting in more uniform freezing of meat products; the multi-directional buffer and drive structure of the plug assembly allows for precise and convenient docking with the socket; the rotating plate and gear transmission structure provide automated drive for the sensor components; and the coordination of the liquid nitrogen pipeline, valve body, and overflow valve ensures stable and controllable liquid nitrogen delivery. In summary, the overall structural design of this invention is reasonable, balancing detection accuracy, ease of operation, equipment stability, and automation, effectively meeting the needs of online detection during the quick-freezing process of meat products.

[0046] like Figure 1-6As shown in Embodiment 1, an online meat inspection component includes a rectangular frame 1, which is welded together from end to end by first square tubes 2. Two sets of symmetrically arranged first wheel seats 3 are mounted on the bottom surface of the rectangular frame 1. The first wheel seats 3 are inverted U-shaped, and first rollers 4 are rotatably connected to the first wheel seats 3. Four symmetrically arranged second square tubes 5 are connected to the top surface of the rectangular frame 1, and the upper sidewalls of the four second square tubes 5 are connected in series via third third tubes 6. The sidewalls of the second square tubes 5 are connected from top to bottom... Four equally spaced support plates 7 form a frame structure, on which a material tray 8 is placed. The material tray 8 has evenly arranged first through holes 9, and the material tray 8 is used to hold meat products. Two second square tubes 5 on the front side have first wire holes 10 on their side walls, with each second square tube 5 having at least three first wire holes 10 (top, middle, and bottom). The side walls of the second square tubes 5 are fixed with feet 11 by bolts. Each foot 11 has a second wire hole 12 communicating with the first wire holes 10, and the foot 11 is connected to a second wire hole 12. A first conduit 13 is connected to a central post 14 at its free end. A second conduit 15 is connected to the included angle of the first conduit 13. A first tube seat 16 is connected to the side wall of the second conduit 15. A sensor assembly 17 is connected to the lower end of the first tube seat 16. The sensor assembly 17 is used for online detection of parameters of meat products. The wiring of the sensor assembly 17 passes through the second conduit 15, the first conduit 13, the foot seat 11, and the second square tube 5. A positioning tube 18 is installed at the upper end of the second square tube 5 located at the front. The positioning tube 18 has two symmetrically arranged first limiting plates 19 connected to its inner wall. A flap 20 is hinged to the bottom surface of each first limiting plate 19. When the flaps 20 are horizontal, they can close the positioning tube 18 to block moisture. A first spring 21 is connected to the bottom surface of the flap 20, and the free end of the first spring 21 is connected to the inner wall of the positioning tube 18. A socket 22 is connected to the end of the sensor assembly 17, located below the flap 20. An insulation component 23 is provided on the outer wall of the sensor assembly 17's wiring. The technical problem it solves is that existing freezing equipment cannot intuitively and in real-time monitor the quality characteristics parameters of meat during the freezing process. Beneficial effects: The flap 20, in conjunction with the first spring 21, can automatically seal the positioning tube 18, effectively blocking moisture and protecting the circuit and socket 22; the heat preservation component 23 provides heat preservation and protection for the circuit of the sensor component 17, ensuring the normal operation of the circuit; the sensor component 17 can realize rapid and non-destructive online detection of quality characteristic parameters of meat products during the freezing process, which not only avoids the waste of samples in traditional sampling and testing, but also solves the defect that offline testing cannot continuously track dynamic changes, greatly improving the accuracy and reliability of detection.

[0047] like Figure 7As shown, as an optimization of Embodiment 1, the thermal insulation component 23 includes a flexible buffer layer 24, a heat insulation layer 25, a moisture-proof layer 28, and a fastener 30 arranged from the inside out. The flexible buffer layer 24 is made of polytetrafluoroethylene film, the inner layer of the heat insulation layer 25 is made of aerogel felt, and the outer layer is made of fiberglass mesh. The moisture-proof layer 28 is made of aluminum-plastic composite film, and the fastener 30 is made of low-temperature resistant nylon cable ties. Beneficial effects: The polytetrafluoroethylene film, as the flexible buffer layer 24, can effectively buffer the impact of external forces on the circuit; the heat insulation layer 25, composed of aerogel felt and fiberglass mesh, has excellent heat insulation effect and can reduce the impact of temperature changes on the circuit; the aluminum-plastic composite film moisture-proof layer 28 can effectively block water vapor and prevent the circuit from getting damp; the low-temperature resistant nylon cable ties are firmly fixed and adaptable to low-temperature environments, so that the structure of each layer of the thermal insulation component 23 is stably attached to the circuit, comprehensively improving the thermal insulation, buffering, and moisture-proof protection effect of the sensor component 17 circuit.

[0048] like Figure 8 As shown, as an optimization of Embodiment 1, it also includes a processor 32, an illumination module 33, a near-infrared spectrometer 34, and a fiber optic converter 35. The near-infrared spectrometer 34 is connected to the processor 32 via a USB data cable 36, and the processor 32 is connected to the fiber optic converter 35 via an RS232 data cable 37. The illumination module 33 is connected to the fiber optic converter 35 via a first optical fiber 38, and the fiber optic converter 35 is connected to the sensor assembly 17 via a second optical fiber 39. The near-infrared spectrometer 34 is connected to the sensor assembly 17 via the fiber optic converter 35. The illumination module 33 is a halogen tungsten lamp. The second optical fiber 39 includes a splitting fiber 41 and a combining fiber 42. The splitting fiber 41 is connected to the fiber optic converter 35, and the combining fiber 42 is connected to the sensor assembly 17. The middle section of the combining fiber 42 is equipped with a mutually compatible socket 22 and a plug. Working process: The needle 53 of the sensor assembly 17 is aligned with the meat product; the illumination module 33 provides illumination for the sensor assembly 17; the sensor assembly 17 is inserted into the meat product at a preset depth; the near-infrared spectrometer 34 collects data from the meat product sequentially through the sensor assembly 17 according to the sequence and time interval preset by the fiber optic converter 35; the near-infrared spectrometer 34 sends the generated spectral data to the processor 32, which processes the spectral data and compares the processing result with a preset reference value to obtain the quality grade. This invention utilizes the sensor assembly 17 to perform rapid, non-destructive online detection of quality characteristic parameters during the freezing process of meat products. This overcomes the destructive testing of traditional sampling methods, which wastes samples, and also overcomes the limitations of offline testing, which cannot continuously track parameter changes throughout the entire freezing process of meat, only acquiring discrete time-point data. This makes it difficult to fully reflect the dynamic changes in the freezing process, potentially leading to biased judgments of quality characteristics and affecting the accuracy of subsequent test results.

[0049] like Figure 9As shown, as an optimization of Embodiment 1, the sensor assembly 17 includes a sleeve 43 connected to the first tube seat 16. A second tube seat 44 is slidably connected to the inner wall of the sleeve 43. The flange of the second tube seat 44 has first spring holes 45 arranged at equal angles. A second spring 46 is installed in the first spring hole 45. A lever 47 is installed on the outer wall of the second tube seat 44. An optical fiber probe 48 is installed in the middle of the second tube seat 44. The optical fiber probe 48 is used to insert into meat products for quality detection. The optical fiber probe 48 includes a fixing tube 49. A nut head 50 is screwed onto the external thread of the fixing tube 49. The nut head 50 is located outside the second tube seat 44. An optical fiber seat 51 is threaded to the inner wall of the fixing tube 49. The probe housing 52 is installed between the fixing tube 49 and the nut head 50 for inserting the second optical fiber 39. The lower end of the probe housing 52 has a needle 53, and the top surface of the probe housing 52 has a blind hole 54. A tilted reflector 55 is installed at the lower end of the blind hole 54. An inner tube 56 is installed inside the blind hole 54, with its lower end abutting against the reflector 55. An optical fiber sleeve 57 is installed on the inner wall of the inner tube 56. The optical fiber sleeve 57 is used to position the second optical fiber 39, which faces the reflector 55. A portion of the second optical fiber 39 serves as the input optical fiber, and the other portion serves as the output optical fiber. The outer wall of the probe housing 52 has a light-transmitting hole 58, which corresponds to the reflector 55. A window 59 is installed on the light-transmitting hole 58. The technical problems that can be solved are: inconvenient insertion and resetting of the probe housing 52 in the sensor assembly 17, and unstable installation and positioning of the optical fiber probe 48. During testing, the input optical fiber transmits light to the reflector 55, which projects the light through the aperture 58 onto the meat product. The reflected light is then reflected by the reflector 55 back to the output optical fiber, completing data acquisition. Beneficial effects: The combination of the lever 47 and the second spring 46 facilitates the insertion and resetting of the optical fiber probe 48, making operation convenient; the threaded connection between the nut head 50 and the optical fiber seat 51 ensures a secure and stable installation of the optical fiber probe 48; the combination of the reflector 55, aperture 58, and window 59 optimizes light transmission and reflection, improving detection accuracy; the reasonable structural design ensures the stable and reliable operation of the sensor assembly 17.

[0050] like Figure 10 and 11As shown in Embodiment 2, unlike Embodiment 1, the sensor assembly 17 includes a third tube seat 60 connected to the first tube seat 16. Two symmetrically arranged shock-absorbing springs 61 are hinged to the inner wall of the third tube seat 60. A fourth tube seat 62 is hinged to the free end of each shock-absorbing spring 61. An optical fiber probe 48 is mounted on the fourth tube seat 62. A lever 63 is connected to the side wall of the fourth tube seat 62, and the lever 63 is slidably connected to the third tube seat 60. When both shock-absorbing springs 61 are simultaneously pointing upwards, the optical fiber probe 48 is quickly pulled out of the meat product; when both shock-absorbing springs 61 are simultaneously pointing downwards, the optical fiber probe 48 is quickly inserted into the meat product. Beneficial effects: The shock-absorbing springs 61 and lever 63 work together to enable rapid insertion and removal of the optical fiber probe 48 from the meat product, improving operational efficiency; the shock-absorbing springs 61 provide cushioning and shock absorption, preventing damage to the probe housing 52 or the meat product during insertion and removal, ensuring the safety and reliability of the detection process; the structure is simple, the operation is convenient, and it adapts to different detection scenarios.

[0051] like Figure 12-14As shown, further, a liquid nitrogen quick-freezing cabinet using an online meat detection component is proposed, including a cabinet body 64. A cabinet door 65 is connected to the front side of the cabinet body 64 via a hinge 66, and the cabinet door 65 is fixed to the cabinet body 64 by a wheel handle lock 67. Two symmetrical first tracks 68 are installed on the inner bottom surface of the cabinet body 64. The top surface of the first track 68 has a first guide groove 69, and a first roller 4 rolls along the first guide groove 69 of the first track 68. An adjusting seat 70 is installed on the inner bottom surface of the cabinet body 64. The adjusting seat 70 is U-shaped, and a second limiting plate 72 is fixed to the adjusting seat 70 by a positioning bolt 71. The second limiting plate 72 is used to block the rectangular frame 1. A first partition 73 is installed inside the cabinet body 64, dividing the internal space of the cabinet body 64 into two parts, one chamber serving as a quick-freezing chamber. The quick-freezing chamber 74 and the circulation chamber 75 are separate chambers. A liquid nitrogen pipe 76 is installed inside the quick-freezing chamber 74 of the cabinet 64, and an atomizing nozzle 77 is installed on the liquid nitrogen pipe 76. Four equally spaced second partitions 78 are installed inside the circulation chamber 75, dividing the circulation chamber 75 into four independent chambers 79. An air inlet 80 is provided on the upper side wall of the first partition 73, and four air outlets 81 are provided on the first partition 73. The air outlets 81 are arranged from top to bottom and correspond to the four independent chambers 79. An exhaust fan 82 is installed on each air outlet 81, enabling four independent nitrogen circulations in the quick-freezing chamber 74, resulting in more consistent freezing of meat products. A plug assembly 83 is installed on the top surface of the cabinet 64, and the plug assembly 83 is compatible with a socket 22. Technical problems that can be solved: Poor compatibility between the online meat inspection component and the blast freezer; inconvenient movement and unstable positioning of the component within the freezer 64; uneven nitrogen circulation within the blast freezer, resulting in inconsistent freezing levels of meat products; inconvenient electrical connection between the blast freezer and the inspection component, lacking a suitable connection structure. During operation, the atomizing nozzle 77 sprays liquid nitrogen to quickly freeze the meat products within the blast freezer chamber 74, and the exhaust fan 82 operates to create four independent nitrogen circulations within the blast freezer chamber 74. Beneficial effects: The online meat inspection component, through the cooperation of the first roller 4 and the first track 68, facilitates movement within the freezer 64; the second limiting plate 72 securely positions the component, improving the compatibility between the component and the blast freezer; the four independent nitrogen circulations ensure uniform nitrogen circulation within the blast freezer, resulting in more consistent freezing levels of meat products and guaranteeing freezing quality; the plug component 83 is compatible with the socket 22, enabling convenient electrical connection between the blast freezer and the inspection component, improving ease of use.

[0052] like Figure 15-21As shown, in a further optimization, the plug assembly 83 includes a first pipe 84, the lower end of which is located inside the cabinet 64. A guide seat 85 is installed on the top surface of the first pipe 84, and a second pipe 86 is slidably connected to the guide seat 85. A first telescopic rod 87 is connected to the side wall of the second pipe 86, and a first support seat 88 is connected to the tail end of the first telescopic rod 87. The first support seat 88 is U-shaped and connected to the top surface of the cabinet 64. A bearing seat 89 is installed inside the second pipe 86, and symmetrically arranged second tracks 90 are installed on the bearing seat 89. A slide rod 91 is slidably connected to the second track 90. ​​The side wall of the slide rod 91 has a toothed groove 92, and a drive gear 93 meshes on the toothed groove 92. The drive gear 93 is located on the bearing seat 89 and is driven by a first motor 94. The inner wall of the second pipe 86 is connected to... There is an insulation component 23. The lower end of the slide rod 91 is connected to a first slide seat 95, which is adapted to the second pipe 86. The bottom surface of the first slide seat 95 is connected to an insertion tube 96. The lower end of the insertion tube 96 has a chamfered structure. The inner side wall of the insertion tube 96 has a groove 97. A slide bar 98 is slidably connected in the groove 97. A vertical rod 99 is connected to the slide bar 98. A third spring 100 is connected to the top surface of the slide bar 98. The free end of the third spring 100 is connected to the groove 97. The bottom surface of the vertical rod 99 is connected to a first carrier plate 101. A plug is connected to the bottom surface of the first carrier plate 101. The plug is adapted to the socket 22. A wedge rod 102 is connected to the side wall of the first carrier plate 101. The wedge rod 102 is used to open the flap 20. A bundled optical fiber 42 is connected to the plug. The bundled optical fiber 42 passes through the first carrier plate 101, the vertical rod 99, the first slide seat 95, and the slide rod 91. The technical problems that can be solved are: the plug of the plug assembly 83 is inconvenient to mate with the socket 22 of the detection assembly, the flap 20 is difficult to open automatically during the mate process, the mate accuracy is low, and the stability of signal transmission is affected. The movement process is as follows: during mate, the first telescopic rod 87 pushes the second pipe 86 to adjust its height, the first motor 94 drives the drive gear 93 to move the slide rod 91 down along the second track 90, the wedge rod 102 moves down to open the flap 20, the chamfered structure of the insertion tube 96 guides the plug and socket 22, the third spring 100 acts as a buffer during the mate process; the insulation assembly 23 provides insulation protection for the bundled optical fiber 42. Beneficial effects: The first telescopic rod 87, the drive gear 93 and the slide rod 91 work together to achieve precise lifting and moving of the plug; the wedge rod 102 automatically opens the flip plate 20; the chamfered structure of the insertion tube 96 guides the plug and socket 22, improving the convenience and accuracy of docking; the third spring 100 acts as a buffer to avoid rigid impact during docking and protect the plug and socket 22; the heat insulation component 23 provides heat insulation protection for the bundled optical fiber 42, ensuring signal transmission stability and improving overall connection reliability.

[0053] like Figure 22-24As shown, further optimization involves connecting a second support base 103 to the top surface of the first carrier plate 101. The second support base 103 is U-shaped, and a third track 104 is connected to its vertical section. A second slide block 105 is slidably connected to the third track 104, and a second carrier plate 106 is connected to the second slide block 105. A fourth spring 107 is connected to the second carrier plate 106, and its free end is connected to the second support base 103. A third carrier plate 108 is connected to the second carrier plate 106 with a gap. The end face of the third carrier plate 108 has a through groove 109, and a fifth spring 110 is connected to the inner wall of the through groove 109. The free end of the fifth spring 110 is connected to a fourth carrier plate 111, on which a plug is mounted. The plug can float, providing good fault tolerance and more accurate insertion. The technical problem solved is the lack of a multi-directional buffer adjustment structure during plug docking, resulting in low fault tolerance and difficulty in compensating for docking deviations, leading to inaccurate insertion. Movement Process: During docking, the lateral force on the plug is adjusted by the compression of the fifth spring 110 by the fourth carrier plate 111, while the vertical force is adjusted by the compression of the fourth spring 107 by the second carrier plate 106 and the sliding adjustment of the second slide block 105 along the third track 104, thus achieving plug floating. Beneficial Effects: The cooperation of the fourth spring 107, the fifth spring 110, the second slide block 105, and the third track 104 enables the plug to have multi-directional floating adjustment capabilities, improving docking error tolerance, effectively compensating for docking deviations, ensuring more accurate insertion, reducing docking failures, and improving connection stability and reliability.

[0054] like Figure 25-27As shown, in a further optimization, two symmetrically arranged first bearing seats 112 are connected to the side wall of the cabinet 64. A rotating rod 113 is rotatably connected to the first bearing seat 112. A first bevel gear 114 is connected to the rotating rod 113 located outside the cabinet 64. A gearbox 115 is connected to the outer wall of the cabinet 64. A first gear 116 and a second gear 117 are rotatably connected inside the gearbox 115. The first gear 116 is driven by a second motor 118. The first gear 116 meshes with the second gear 117. A second bevel gear 119 is connected to the shaft end of the second gear 117. The first bevel gear 114 meshes with the second bevel gear 119. A first rotating plate 120 is located on the side wall of the rotating rod 113 inside the cabinet 64. The first rotating plate 120 is used to drive the dial plate 47 or the lever 63 to descend. The technical problem that can be solved is that driving the dial plate 47 or the lever 63 of the sensor assembly 17 is inconvenient, making automated operation difficult and affecting the continuity of the detection process. Movement Process: During operation, the second motor 118 drives the first gear 116 to rotate, which in turn drives the second gear 117 and the second bevel gear 119 to rotate. The second bevel gear 119 meshes with and drives the first bevel gear 114 and the rotating rod 113 to rotate. The rotating rod 113 drives the first rotating plate 120 to rotate, and the first rotating plate 120 drives the dial plate 47 or the lever 63 to descend. Beneficial Effects: Through the cooperation of the motor, gears, bevel gears, rotating rod 113, and first rotating plate 120, the automated driving of the dial plate 47 or the lever 63 is achieved, improving driving efficiency and operational accuracy, ensuring the continuity and automation of the testing process, and reducing labor costs.

[0055] like Figure 28 As shown, in a further optimization, a fifth carrier plate 121 is connected to the first rotating plate 120, and a sixth carrier plate 122 is hinged to the fifth carrier plate 121. The sixth carrier plate 122 is used to drive the dial plate 47 or the lever 63 to descend. A sixth spring 123 is connected between the fifth carrier plate 121 and the sixth carrier plate 122. The technical problem that can be solved is that the first rotating plate 120 lacks a buffer structure when driving the dial plate 47 or the lever 63, which easily generates rigid impacts during the driving process, leading to component wear and affecting driving stability and service life. Movement process: When the first rotating plate 120 rotates, it drives the fifth carrier plate 121 and the sixth carrier plate 122 to rotate. The sixth carrier plate 122 contacts the dial plate 47 or the lever 63 and drives it to descend. During the driving process, the sixth spring 123 extends and retracts according to the force, playing a buffering role. Beneficial effects: The sixth spring 123 cooperates with the hinged sixth carrier plate 122 to buffer and dampen the shock when the drive plate 47 or lever 63 descends, avoiding wear of components caused by rigid impact, improving drive stability and reliability, extending the service life of components, and ensuring the continuous and stable operation of the detection component.

[0056] like Figure 29 and 30As shown, further optimization involves two symmetrically arranged second bearing seats 124 rotatably connected inside the cabinet 64. A main pipe 125 is rotatably connected to the second bearing seats 124. A valve body 126 is installed in the middle of the main pipe 125, and a block 127 is located in the middle of the valve body 126. One end of the valve body 126 is connected to a branch pipe 128, and the free end of the branch pipe 128 is connected to a liquid nitrogen pipe 76. An atomizing nozzle 77 is installed on the liquid nitrogen pipe 76. The other end of the valve body 126 is connected to an overflow valve 129. An auxiliary support 130 connects the main pipe 125 and the liquid nitrogen pipe 76. A gear set 131 is connected to the main pipe 125 located outside the cabinet 64, and the gear set 131 is driven by a third motor 132. This solves the technical problem of fixing the liquid nitrogen injection position. Movement process: During operation, the third motor 132 drives the gear set 131 to rotate the main pipe 125 and the valve body 126; at the same time, the liquid nitrogen pipe 76 and the atomizing nozzle 77 swing, making the freezing effect more uniform.

[0057] like Figure 31 As shown, further optimizations include a second guide groove 133 on the side of the first track 68, a second wheel seat 134 mounted on the first wheel seat 3, and a second roller 135 mounted on the second wheel seat 134. The second roller 135 is adapted to the second guide groove 133, which improves the accuracy of the plug and socket 22 docking.
