Description

Technical Field

[0001] This invention relates to a temperature measurement production line for testing the performance of mosquito coil devices. Background Technology

[0002] With the increasing application of integrated circuits in electric mosquito repellent devices, the performance requirements for their core component, the circuit board, are becoming increasingly stringent, and the corresponding quality control standards are constantly being raised. This necessitates comprehensive performance testing during the circuit board production process. Infrared thermography can accurately detect the temperature distribution of the circuit board during operation, promptly identifying potential defects such as abnormal chip heating and short circuits, preventing substandard circuit boards from entering the assembly stage and causing product malfunctions or safety hazards. Simultaneously, the power connector pins of the circuit board, as a crucial connection structure to functional components, also require rigorous structural strength testing. Insufficient pin strength can easily lead to bending, deformation, or even breakage under slight external forces during product assembly, transportation, or long-term use, directly causing poor circuit contact and power outages, severely impacting the reliability of the electric mosquito repellent device. However, existing testing methods, including but not limited to high and low temperature testing and online continuity testing, mostly rely on manual operation. This not only results in high labor costs and low testing efficiency, but also in inconsistent standards for judging test results. Especially in projects that require quantitative evaluation, such as pin bending strength, manual judgment is prone to errors, ultimately leading to inconsistent quality of circuit boards for electric mosquito coils leaving the factory, which directly affects the quality stability of end products. Chinese patent application number CN202310946865.6, entitled "A Temperature Measurement Production Line," discloses a temperature measurement production line for mosquito coil devices. This production line relates to the field of component testing technology and includes a conveyor frame, a temperature measuring component, and a pressure-resistant component. The conveyor frame has several conveyor plates, and a front box and a rear box are fixedly connected to both sides of the conveyor frame. A central control module is also installed on the conveyor frame. Transmission components are installed in both the front and rear boxes. The temperature measuring component, including an infrared temperature probe, is mounted on the conveyor frame. The temperature measuring component measures the temperature of components on the conveyor plates. The pressure-resistant component, including a probe assembly, is mounted on the conveyor frame. The pressure-resistant component allows the probe assembly to move vertically. An auxiliary component is also included, located on the side of the conveyor frame, to assist the infrared temperature probe in its operation. Through the cooperation of these structures, this invention achieves unified and automatic testing of components, ensuring compliance with factory standards. However, the lack of a strength testing structure in the production line makes the overall structure redundant, which is not conducive to improving the effectiveness of the equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a temperature measurement production line for testing the performance of mosquito coil devices. Its structure and layout are more reasonable, facilitating more comprehensive testing and improving the effectiveness of the structure.

[0004] To achieve the above objectives, the present invention provides a temperature measurement production line for testing the performance of mosquito coils, comprising a conveyor frame with several conveyor plates, a front box and a rear box at both ends of the conveyor frame, each containing a lifting mechanism, a temperature measuring mechanism, a pressure-resistant mechanism, and a pin testing mechanism for detecting pin deformation, all disposed on the conveyor frame between the front and rear boxes, several rows of test seats for accommodating mosquito coils to be tested are arranged on the conveyor plates, a movable frame is slidably mounted on the conveyor plate, and test platforms are respectively arranged on the movable frame at the positions corresponding to the test seats, a drive platform is also provided on the side of the conveyor plate, and several drive components for pushing the movable frame are arranged on the drive platform, the movable frame also being equipped with... The device includes a return spring for resetting the movable frame. The test platform is equipped with a test slot and a contact slot. One end of the contact slot is exposed outside the test slot, while the other end is connected to it. A contact block for applying pressure to the mosquito coil holder's prongs is slidably disposed within the contact slot. A loading spring abuts against the bottom surface of the contact slot. A contact platform is provided at the end of the contact block that inserts into the test slot. A metal spring for clamping the mosquito coil holder's prongs is provided within the test slot. A driven block for sliding due to contact with the mosquito coil holder's prongs is also provided on the inner wall of the test slot. The driven block has a contact ramp for contacting the contact block, causing it to sink into the contact slot. The contact ramp abuts against the contact platform. A contact spring also abuts between the driven block and the test slot. This structural layout is more rational, facilitating more comprehensive testing and improving the device's usability.

[0005] The advantages of this design are as follows: By integrating the temperature measuring mechanism, pressure resistance mechanism, and plug testing mechanism onto the conveyor frame, a one-stop comprehensive testing system for mosquito coils is achieved, encompassing temperature performance, pressure resistance, and plug structural strength. This eliminates the need for additional independent testing equipment, streamlining the testing process and improving efficiency. By configuring a movable frame and testing platform on the test seat of the conveyor plate, and utilizing the contact block within the contact groove in conjunction with the loading spring, the bottom contact force experienced by the plug during actual assembly and use can be accurately simulated, effectively testing the plug's resistance to deformation. Simultaneously, the driven block and contact slope within the test groove, which are slid due to plug contact, allow for targeted testing of the plug's tip's load-bearing capacity, enabling multi-dimensional and comprehensive testing. When the plug deformation exceeds a preset threshold, its position changes, allowing for rapid identification and determination of defective products by the plug testing mechanism. This automated screening prevents defective products from entering the next process, significantly improving the stability and reliability of the mosquito coil's final product quality.

[0006] As a further feature of the present invention, the movable frame is provided with several rows of support beams, and two movable beams are slidably arranged on the support beams. The test platform is correspondingly arranged on the movable beams. Holding springs for keeping the movable beams centered are respectively provided on both sides of the movable beams. A pusher is also provided on the drive platform. A channel for the output shaft of the pusher is provided between the two movable beams. Several continuously arranged abutting flanges are provided on the output shaft of the pusher. The outer peripheral walls of the abutting flanges abut against the movable beams.

[0007] The advantages of this design are as follows: By incorporating support beams, slidingly connected movable beams, and retaining springs on the movable frame, the movable beams remain centered when no external force is applied, ensuring precise alignment between the test platform and the test seat and guaranteeing consistent initial positions for the pin tests. The output shaft of the pusher on the drive platform passes through the channel between the two movable beams, and its continuous abutment flanges on its outer periphery evenly contact the movable beams, applying a lateral thrust to the movable frame. This allows for testing the lateral strength of the pins, detecting their lateral bending resistance, and improving the accuracy of the pin deformation resistance test. Simultaneously, the retaining springs enable the movable beams to quickly return to center after the pusher resets, preparing for the next test. This adapts to the continuous operation requirements of the production line, further enhancing the continuity and efficiency of the testing.

[0008] As a further feature of the present invention, the conveyor frame is also provided with a support platform, the support platform is provided with a lifting frame and a lifting motor for controlling the height of the lifting frame, the lifting frame is provided with a support seat for supporting the output shaft of the pusher, the drive platform is also provided with a lifting frame and a lifting motor for driving the lifting frame to lift, and the pusher is provided on the lifting frame.

[0009] The advantages of this setup are as follows: In non-testing conditions, the lifting motor drives the entire lifting frame to rise, which in turn raises the pushing component and output shaft synchronously. This completely separates the output shaft from the conveyor plate's movement path, eliminating interference and collisions between the output shaft and the conveyor plate or the mosquito coil unit under test. This clears obstacles for smooth conveying, ensuring the high efficiency of continuous production line transport, while also reducing component wear and extending equipment lifespan. In testing conditions, the lifting motor drives the lifting frame to precisely descend, ensuring the pushing component's output shaft fits precisely into the channel between the two movable beams, achieving accurate alignment between the output shaft and the movable beams. Simultaneously, the lifting motor can flexibly adjust the support height of the lifting frame, providing stable support for the output shaft through the support seats on the lifting frame. This effectively counteracts the output shaft's own weight and force shifts during the pushing process, ensuring the output shaft remains in a horizontal and balanced state at all times.

[0010] As a further feature of the present invention, a stop groove is provided on the side wall of the conveyor plate, a stop seat is provided on the conveyor frame, a stop crank arm and a stop cylinder for driving the stop crank arm to swing are provided on the stop seat, one arm of the stop crank arm is located close to the stop groove, and the other arm abuts against the output end of the stop cylinder.

[0011] The advantages of this design are as follows: By incorporating a stop groove on the side wall of the conveyor plate, along with the stop seat, stop crank arm, and stop cylinder on the conveyor frame, the stop crank arm can be quickly driven into the stop groove when the conveyor plate reaches the testing station, achieving precise positioning and fixation of the conveyor plate. During testing, there is no displacement deviation in the conveyor plate, preventing misalignment of the pins with the test slots and contact blocks due to conveyor plate wobbling, or component position shifts during temperature and pressure tests, effectively improving the accuracy and repeatability of various tests. Simultaneously, the crank arm structure driven by the stop cylinder responds quickly, adapting to the continuous conveying rhythm of the production line, ensuring testing stability without affecting conveying efficiency.

[0012] As a further feature of the present invention, a rolling wheel is provided at one end of the stop crank arm that abuts against the stop groove.

[0013] The beneficial effects of this design are as follows: By installing a rolling wheel at the end of the stop arm that contacts the stop groove, the sliding friction between the stop arm and the stop groove is converted into rolling friction. This significantly reduces the frictional force when they come into contact, reduces component wear, and extends the service life of the stop arm and the conveyor plate. Simultaneously, the smoothness of rolling friction makes the process of the stop arm engaging or disengaging from the stop groove more stable, avoiding conveyor plate jamming or stop positioning deviation caused by excessive frictional resistance. This ensures the smooth operation of the production line and further improves overall inspection efficiency.

[0014] As a further feature of the present invention, the test pin testing mechanism includes a test frame, a test plate, and a test motor for driving the test plate to rise and fall. The test motor is mounted on the test frame, and the test plate is connected to the output end of the test motor. The test plate is provided with test stations corresponding to the test base positions, and the test stations are provided with test slots corresponding to the mosquito coil plug positions. The inner wall of the test slot is provided with contact pieces for generating electrical signals by contacting the plug.

[0015] The advantages of this setup are as follows: By using a detection motor to drive the detection plate's lifting and lowering, precise coordination with the production line's conveyor rhythm can be achieved, automating the pin detection process without manual intervention and significantly improving detection efficiency. The detection stations on the detection plate correspond one-to-one with the test seats. The contact plates on the inner wall of the detection slot can precisely contact the pins. When the pin deformation exceeds a threshold, the contact state with the contact plate changes (e.g., poor contact, contact position shift), and the change in electrical signal quickly determines whether the product is qualified. Compared to manual visual inspection, this not only reduces subjective error but also achieves quantitative and automated screening of detection results, improving the accuracy and timeliness of determining unqualified products. Regarding the contact plate structure design, contact plates can be installed on the side walls and bottom wall of the detection slot. The side wall contact plates have one end fixed to the slot wall and the other end slightly protruding into the slot, forming a left-right clamping area to match the normal reference position in the pin width direction. A conductive contact plate is centrally located on the bottom wall, with one end fixed and the upper surface slightly convex, forming a U-shape with the side wall contact plates. The contact area covers the normal contact position at the bottom of the pins. The side wall contact pieces are connected in parallel with wires to the positive channel of the signal acquisition module, and the bottom wall contact piece is connected to the negative channel of the signal acquisition module, forming a loop structure. The signal acquisition module is integrated into the detection board and electrically connected to the central control module via a ribbon cable. The loop is equipped with a low-voltage power supply to ensure safety and signal stability. The incense burner is also equipped with a positioning post. The end of the positioning post has a contact flange along the circumferential direction. In the initial state, when the detection board has not descended, the three wall contact pieces are not in contact, and the loop is broken. The signal acquisition module outputs three initial disconnect signals. If the pins are not deformed, or the deformation is within the threshold: the left and right sides of the pins are elastically clamped to the side wall contact pieces, and the bottom is in close contact with the bottom wall contact piece, and the circuit is fully conductive. The signal acquisition module detects the three conductive stable low-resistance signals in real time and immediately transmits qualified electrical signals to the central control module. If the pin deformation exceeds the threshold and bending deformation occurs to the left or right: the pins cannot simultaneously contact the side wall contact pieces, and the circuit is only conductive at the bottom wall or completely disconnected. The signal acquisition module captures a single-sided conductive or open circuit signal.

[0016] As a further feature of the present invention, the test plate is also provided with a positioning post corresponding to the mosquito coil device to be tested, and the end of the positioning post is provided with an abutting flange along the circumferential direction.

[0017] The advantages of this design are as follows: By incorporating positioning posts on the test plate, the mosquito coil holder can be precisely positioned when placed on the test base, preventing misalignment that could cause the pins to fail to accurately enter the test or detection slots, thus ensuring smooth testing. The circumferential contact flange at the end of the positioning post forms a reliable contact with the surface of the mosquito coil holder, enhancing its positioning stability during testing and preventing displacement due to the forces exerted by the contact and driven blocks. This ensures accurate transmission of the test force on the pins, further improving the accuracy of the pin deformation resistance test and subsequent inspections, and guaranteeing the reliability of the test results.

[0018] As a further feature of the present invention, a guide post and a guide rod are provided between the detection plate and the detection frame, and the guide post and the guide rod are inserted into each other.

[0019] The beneficial effects of this design are as follows: By incorporating interlocking guide posts and rods between the detection plate and the detection frame, the vertical movement of the detection plate is precisely guided, ensuring it remains vertical throughout its movement and preventing tilting or offset. This structure effectively prevents misalignment between the detection slot and the mosquito coil holder pins, ensuring precise contact between the contact plate and the pins. This avoids misjudgments or missed detections due to alignment deviations, significantly improving the reliability and consistency of pin deformation detection and guaranteeing the accuracy of automated screening results.

Detailed Implementation

[0021] This invention provides a first embodiment of a temperature measurement production line for testing the performance of mosquito coil devices, such as... Figures 1 to 6As shown, the device includes a conveyor frame 1 with several conveyor plates 3. A front box 21 and a rear box 22 are located at both ends of the conveyor frame 1, each containing a lifting mechanism. Between the front box 21 and the rear box 22, a temperature measuring mechanism 4, a pressure-resistant mechanism 5, and a pin testing mechanism 6 for detecting pin deformation are also located on the conveyor frame 1. Several rows of test seats for accommodating mosquito coil devices under test are arranged on the conveyor plates 3. Movable frames 32 are slidably mounted on the conveyor plates 3, with test stands 33 corresponding to the test seats on the movable frames 32. A drive platform 11 is also located beside the conveyor plates 3 on the conveyor frame 1. The drive platform 11 has several drive components 111 for pushing the movable frames 32. A return spring 3 is also fitted onto the movable frames 32 for resetting them. 4. The test platform 33 is provided with a test groove and a contact groove. One end of the contact groove is exposed outside the test groove, and the other end is connected to the test groove. A contact block 331 for applying pressure to the mosquito coil insert is slidably disposed in the contact groove. A loading spring 333 is in contact between the contact block 331 and the bottom surface of the contact groove. A contact platform 332 is provided at the end of the contact block 331 that is inserted into the test groove. A metal spring 336 for clamping the mosquito coil insert is provided in the test groove. A driven block 334 for sliding due to contact with the mosquito coil insert is also provided on the inner wall of the test groove. A contact inclined surface is provided on the driven block 334 for contacting the contact block 331 so that the contact block 331 is inserted into the contact groove. The contact inclined surface abuts against the contact platform 332. A contact spring 335 is also in contact between the driven block 334 and the test groove. The advantages of this design are as follows: By integrating the temperature measuring mechanism 4, pressure-resistant mechanism 5, and pin testing mechanism 6 onto the conveyor frame 1, a one-stop comprehensive testing system for mosquito coils, encompassing temperature performance, pressure resistance, and pin structural strength, is achieved. This eliminates the need for additional independent testing equipment, simplifies the testing process, and improves testing efficiency. By configuring a movable frame 32 and a testing platform 33 on the testing seat of the conveyor plate 3, and utilizing the contact block 331 within the contact groove in conjunction with the loading spring 333, the bottom contact force experienced by the mosquito coil pins during actual assembly and use can be accurately simulated, effectively testing the pins' resistance to deformation. Simultaneously, by utilizing the driven block 334 and the contact slope within the testing groove, which slide due to the pin's contact, the load-bearing capacity of the pin tips can be specifically tested, achieving a comprehensive, multi-dimensional testing of the pins. When the deformation of the pin exceeds the preset threshold, its position will change. Subsequently, the pin testing mechanism 6 can quickly identify and determine unqualified products, complete automated screening, prevent unqualified products from flowing into the next process, and significantly improve the stability and reliability of the mosquito coil device's factory quality.

[0022] As a further feature of this embodiment, the movable frame 32 is provided with several rows of support beams 34, and two movable beams 35 are slidably mounted on the support beams 34. The test platform 33 is correspondingly mounted on the movable beams 35. Holding springs 36 are provided on both sides of the movable beams 35 to keep them centered. The drive platform 11 is also provided with a pusher 113. A channel 341 is provided between the two movable beams 35 for the output shaft of the pusher 113 to pass through. Several continuously arranged abutment flanges 114 are provided on the output shaft of the pusher 113, and the outer peripheral walls of the abutment flanges 114 abut against the movable beams 35. The beneficial effect of this configuration is that, by providing support beams 34, slidably connected movable beams 35, and holding springs 36 on the movable frame 32, the movable beams 35 always remain centered when no external force is applied, ensuring precise alignment between the test platform 33 and the test seat, and guaranteeing the consistency of the initial position of the pin test. The output shaft of the pusher 113 on the drive platform 11 passes through the channel 341 between the two movable beams 35. The continuous contact flange 114 on its outer peripheral wall can evenly contact the movable beams 35, thereby applying a lateral thrust to the movable frame 32, thus enabling the testing of the lateral strength of the pins and detecting the lateral bending resistance of the pins, improving the accuracy of the pin deformation resistance test. At the same time, the retaining spring 36 can drive the movable beams 35 to quickly return to center after the pusher 113 resets, preparing for the next test, adapting to the continuous operation requirements of the production line, and further improving the continuity and efficiency of the test.

[0023] As a further provision of this embodiment, the conveyor frame 1 is also provided with a support platform 12, on which a lifting frame 121 and a lifting motor for controlling the height of the lifting frame 121 are provided. The lifting frame 121 is provided with a support seat 122 for supporting the output shaft of the pusher 113. The drive platform 11 is also provided with a lifting frame and a lifting motor for driving the lifting frame to rise and fall. The pusher 113 is disposed on the lifting frame. The beneficial effect of this configuration is that, in the non-testing state, the lifting frame is raised as a whole by driving the lifting motor, which can drive the pusher 113 and the output shaft to rise synchronously, so that the output shaft is completely separated from the movement path of the conveyor plate 3, completely avoiding interference and collision between the output shaft and the conveyor plate 3 and the mosquito coil device under test, clearing obstacles for the smooth conveying of the conveyor plate 3, ensuring the high efficiency of continuous conveying of the production line, reducing component wear, and extending the service life of the equipment. In the test state, the lifting motor drives the lifting frame to descend precisely, so that the output shaft of the pushing component 113 is precisely embedded in the channel 341 between the two movable beams 35, achieving precise alignment between the output shaft and the movable beams 35; at the same time, the lifting motor can flexibly adjust the support height of the lifting frame 121, and the support seat 122 on the lifting frame 121 forms a stable support for the output shaft, effectively offsetting the weight of the output shaft itself and the force offset during the pushing process, ensuring that the output shaft is always in a horizontal balance state.

[0024] As a further feature of this embodiment, a stop groove 31 is provided on the side wall of the conveyor plate 3, and a stop seat 7 is provided on the conveyor frame 1. The stop seat 7 is provided with a stop crank arm 71 and a stop cylinder 72 for driving the stop crank arm 71 to swing. One arm of the stop crank arm 71 is positioned close to the stop groove 31, and the other arm abuts against the output end of the stop cylinder 72. The beneficial effect of this configuration is that, by providing a stop groove 31 on the side wall of the conveyor plate 3, and cooperating with the stop seat 7, stop crank arm 71, and stop cylinder 72 on the conveyor frame 1, the arm of the stop crank arm 71 can be quickly driven into the stop groove 31 when the conveyor plate 3 moves to the test station, achieving precise positioning and fixation of the conveyor plate 3. During the test, the conveyor plate 3 has no displacement deviation, which can avoid misalignment of the pins with the test groove and the contact block 331 due to the shaking of the conveyor plate 3, or component position shift during temperature and pressure tests, effectively improving the accuracy and repeatability of various tests. Meanwhile, the crank arm structure driven by the stop cylinder 72 responds quickly and can adapt to the continuous conveying rhythm of the production line, ensuring test stability without affecting conveying efficiency.

[0025] As a further feature of this embodiment, a rolling wheel 73 is provided at one end of the stop arm 71 that abuts against the stop groove 31. The beneficial effects of this configuration are: by providing the rolling wheel 73 at the end of the stop arm 71 that abuts against the stop groove 31, the sliding friction between the stop arm 71 and the stop groove 31 is converted into rolling friction, significantly reducing the frictional force when they come into contact, reducing component wear, and extending the service life of the stop arm 71 and the conveyor plate 3. Simultaneously, the smoothness of the rolling friction makes the process of the stop arm 71 engaging or disengaging from the stop groove 31 more stable, avoiding jamming of the conveyor plate 3 or stop positioning deviation due to excessive frictional resistance, ensuring the smooth operation of the production line, and further improving the overall testing efficiency.

[0026] As a further feature of this embodiment, the test pin testing mechanism 6 includes a testing frame 61, a testing plate 63, and a testing motor 62 for driving the testing plate 63 to rise and fall. The testing motor 62 is mounted on the testing frame 61, and the testing plate 63 is connected to the output end of the testing motor 62. The testing plate 63 has testing stations 631 corresponding to the test base positions, and each testing station 631 has a testing groove corresponding to the mosquito coil pin position. The inner wall of the testing groove is provided with contact pieces for generating electrical signals upon contact with the pin. The advantage of this configuration is that by driving the testing plate 63 to rise and fall with the testing motor 62, precise coordination with the conveyor belt rhythm can be achieved, automating the pin testing action without manual intervention and significantly improving testing efficiency. The testing stations 631 on the testing plate 63 correspond one-to-one with the test sockets. The contact plates on the inner wall of the testing groove can make precise contact with the pins. When the pin deformation exceeds the threshold, the contact state between the pin and the contact plate will change (such as poor contact, contact position displacement, etc.). Then, the product's qualification can be quickly determined through changes in electrical signals. Compared with manual visual judgment, this not only reduces subjective error but also realizes the quantification and automated screening of test results, improving the accuracy and timeliness of the judgment of unqualified products. For the structural design of the contact plates, contact plates can be set on the side walls and bottom wall of the testing groove. The contact plates on the side walls are fixed to the groove wall at one end and slightly protrude into the groove at the other end to form a left and right clamping interval, which is adapted to the normal reference position in the width direction of the pin. A conductive contact plate is set in the center of the bottom wall, fixed at one end and slightly convex on the upper surface, forming a U-shape with the contact plates on the side walls. The contact area covers the normal contact position at the bottom of the pin. The contact pieces on both sides are connected in parallel with wires to the positive channel 341 of the signal acquisition module, and the contact piece on the bottom wall is connected to the negative channel 341 of the signal acquisition module, forming a loop structure. The signal acquisition module is integrated into the detection board 63 and electrically connected to the central control module via a ribbon cable. The loop is equipped with a low-voltage power supply to ensure safety and signal stability. The incense burner is also equipped with a positioning post. The end of the positioning post is provided with a contact flange 114 along the circumferential direction. In the initial state, when the detection board 63 has not descended, none of the three wall contact pieces are in contact. When the circuit is disconnected, the signal acquisition module outputs three initial disconnection signals. If the pins are not deformed, or the deformation is within the threshold: the left and right sides of the pins are elastically clamped to the side wall contact pieces, and the bottom is in close contact with the bottom wall contact piece, the circuit is fully conductive, and the signal acquisition module detects the stable low-resistance signals of the three conductive lines in real time and immediately transmits qualified electrical signals to the central control module. If the pin deformation exceeds the threshold and bending deformation occurs to the left or right: the pins cannot simultaneously contact the side wall contact pieces, the circuit is only conductive at the bottom wall or completely disconnected, and the signal acquisition module captures a single-sided conductive or open-circuit signal.

[0027] As a further feature of this embodiment, a positioning post 632 is also provided on the test plate 63 corresponding to the mosquito coil device under test. The end of the positioning post 632 has a circumferentially oriented contact flange. The beneficial effect of this design is that by providing a positioning post on the test plate, the mosquito coil device can be accurately positioned when placed on the test seat, preventing misalignment that could cause the pins to fail to accurately enter the test or detection slots, thus ensuring smooth testing. The circumferential contact flange 114 at the end of the positioning post can reliably contact the surface of the mosquito coil device, enhancing the positioning stability of the mosquito coil device during testing. This prevents displacement of the mosquito coil device due to the forces exerted by the contact block 331 and the driven block 334 during testing, ensuring accurate transmission of the test force on the pins, further improving the accuracy of the pin deformation resistance test and subsequent detection, and ensuring the reliability of the test results.

[0028] As a further feature of this embodiment, a guide post 64 and a guide rod 65 are provided between the detection plate 63 and the detection frame 61, with the guide post 64 and guide rod 65 interlocking. The beneficial effect of this configuration is that, by providing the interlocking guide post 64 and guide rod 65 between the detection plate 63 and the detection frame 61, precise guidance can be provided for the lifting and lowering movement of the detection plate 63, ensuring that the detection plate 63 remains vertical during its up-and-down movement and preventing tilting or deviation. This structure effectively prevents misalignment between the detection slot and the mosquito coil holder pins, ensuring precise contact between the contact piece and the pins, avoiding misjudgments or missed judgments due to alignment deviations, significantly improving the reliability and consistency of pin deformation detection, and guaranteeing the accuracy of automated screening results.

[0029] The above examples are merely one preferred embodiment of the present invention. Ordinary variations and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included within the protection scope of the present invention.
