[0022] The features and other related features of the present application are further described in detail below through examples, so as to facilitate the understanding of the skilled in the art:

[0023] For the convenience of description and understanding, the description related to the positional relationship in the present application, such as front, back, up, down, left, right, outer and inner, please refer to the orientation shown in Figure 2 and Figure 3 .

[0024] As Figures 1 to 5As shown, the handle knob switch testing machine provided in the case comprises a rack 100, and the rack 100 comprises a mounting table 101. The rack 100 serves as the basic frame of the whole testing machine, and provides a mounting platform and a support frame. The mounting table 101 facilitates the installation of related mechanisms. The mounting table 101 is provided with a detection device 200, and the mounting table 101 is also provided with a first conveying mechanism 1 located in front of the detection device 200. The detection device 200 comprises a clamp 2, a detection mechanism 3, a rotating mechanism 4 and a discharging mechanism 5. The clamp 2 is detachably arranged on the mounting table 101. The detection mechanism 3 is arranged on the mounting table 101. The rotating mechanism 4 is suspended above the detection mechanism 3. The discharging mechanism 5 is connected below the clamp 2. The rack 100 is also provided with a second conveying mechanism 6 located below the discharging mechanism 5. The rack 100 is also provided with a central control system 7.

[0025] As above, in specific implementation, the clamp 2 is used to place and fix the handle knob switch material. The first conveying mechanism 1 conveys the handle knob switch material assembled in the previous process into the handle knob switch testing machine of the case, so as to link the previous and subsequent processes. First, the handle knob switch is placed on the clamp 2 by hand. Then, the detection mechanism 3 acts to detect the electrification effect of the handle knob switch on the clamp 2. At the same time, the rotating mechanism 4 drives the handle knob switch to rotate, so as to detect each gear position of the handle knob switch. After the detection is passed, the discharging mechanism 5 acts to discharge the handle knob switch material on the clamp 2 to the second conveying mechanism 6. The handle knob switch material after the detection is conveyed out of the rack 100 by the second conveying mechanism 6.

[0026] In specific implementation, in order to improve the testing efficiency, the detection device 200 is equidistantly provided with a plurality of detection devices. The user can set the corresponding number according to the demand. In the embodiment, the number of detection devices shown is five.

[0027] The first conveying mechanism 1 is horizontally arranged and extends out of the rack 100 at one end and is flush with the rack 100 at the other end. The length thereof can be adaptively adjusted according to the length of the rack 100 and the number of detection devices 200 arranged. In this way, the handle knob switch material can be effectively transmitted to the corresponding position of each detection device 200. Similarly, the second conveying mechanism 6 is horizontally arranged at the left and right ends of the rack 100, so as to correspond to each detection device 200 and receive the material discharged after the detection. The length thereof can also be adaptively adjusted according to the actual demand.

[0028] The case realizes the automation of handle knob switch power-on and knob detection through the setting of the detection device 200, meets the needs of large-scale production, and reduces production costs. The synergy of the detection mechanism 3 and the rotating mechanism 4 ensures that the power-on effect and multi-position function of each handle knob switch can be strictly detected, reducing the defective rate. The setting of the detachable clamp 2 enables the device of the case to adapt to handle knob switches of different specifications, enhancing the versatility and flexibility of the device. At the same time, the clamp 2 is used to place and fix the handle knob switch, ensuring that the handle knob switch remains stable during the detection process, improving the detection accuracy. The first conveying mechanism 1 realizes automatic feeding, and the second conveying mechanism 2 realizes automatic unloading. The combination of the two significantly improves production efficiency. The handle knob switch tester provided by the case not only simplifies the detection process of the handle knob switch, but also greatly improves the stability and accuracy of the detection, thereby providing a solid foundation for subsequent quality detection and packaging processes. Through precise control and efficient connection, the detection quality and efficiency of the product are significantly improved.

[0029] It should be noted that in specific implementation, the case detects the presence or absence of an object, detects the in-place situation of the object, and triggers the action or changes the state of the device by setting multiple induction switches. This related content is a well-known technology in the art, and each induction switch is not described in detail. In specific implementation, those skilled in the art can set corresponding induction switches according to common sense in the art combined with the handle switch assembly device of the case to realize the linkage between each mechanism.

[0030] As shown in Figure 1 , Figure 2 Specifically, the first conveying mechanism 1 of the case includes a first driving roller 11, a first motor 12, a first driven roller 13, and a first conveying belt 14. The first motor 12 is connected with the first driving roller 11 to drive the first driving roller 11 to rotate. The first conveying belt 14 is sleeved between the first driving roller 11 and the first driven roller 13 and can circulate between them. The first motor 12 provides a power source to drive the first driving roller 11 to rotate, and the first driven roller 13 cooperates with the first driving roller 11 to support and guide the movement of the first conveying belt 14. In specific implementation, the first motor 12 is a speed-regulating motor to adjust the conveying speed of the first conveying mechanism 1 as a whole according to needs. First baffles 15 are arranged on both sides of the first conveying belt 14. The first baffles 15 are arranged on both sides of the upper end of the first conveying belt 14 to prevent the handle knob switch material from falling off the first conveying belt 14 during transmission.

[0031] As shown in Figures 1 to 5As shown, specifically, the detection mechanism 3 of the case includes a first fixed seat 31, a first cylinder 32 connected to the first fixed seat 31, and a detection head 33 connected to the front end of the first cylinder 32 and movable with the first cylinder 32, and a conductive needle 34 is arranged on the detection head 33. In specific implementation, after the handle knob switch material is placed on the clamp 2 by manual rotation of the knob, the detection mechanism 3 starts to act, the first cylinder 32 is pushed out to move towards the clamp 2, the conductive needle 34 on the detection head 33 is inserted into the handle knob switch on the clamp 2 to perform power-on detection, and after the detection is completed, the first cylinder 32 is retracted, and the reciprocating motion is performed. The detection mechanism 3 of the case realizes efficient and accurate power-on detection of the handle knob switch.

[0032] Further, in order to improve the detection efficiency and adapt to the detection requirements of different handle knob switches, two detection mechanisms 3 are symmetrically arranged in the case, and two detection mechanisms 3 are arranged at the upper and lower ends of the clamp 2, respectively. Two conductive needles 34 are arranged on the detection head 33. Of course, the user can also configure different detection mechanisms 3 and the number of conductive needles 34 according to the product requirements of different models of handle knob switches.

[0033] Continuing to refer to Figures 1 to 5 As shown, specifically, the unloading mechanism 5 of the case includes a second cylinder 51, a movable seat 52 connected to the front end of the second cylinder 51 and movable with the second cylinder 51, and a bottom plate 53 connected to the upper end of the movable seat 52. The clamp 2 includes a positioning hole 21, an unloading hole 22 passing through the positioning hole 21, and a slot 23 between the positioning hole 21 and the unloading hole 22, and the bottom plate 53 is movably inserted into the slot 23. In specific implementation, when the second cylinder 51 is retracted, the movable seat 52 and the bottom plate 53 are moved, so that the bottom plate 53 is separated from the slot 23 of the clamp 2, at this time the positioning hole 21 and the unloading hole 22 of the clamp 2 are mutually penetrated, and because there is no support of the bottom plate 53, the material in the positioning hole 21 will automatically fall into the unloading hole 22 and finally fall into the second conveying mechanism 6, completing the unloading after detection, and reciprocating movement. When the detection is unqualified, the second cylinder 51 does not retract, at this time the unqualified handle knob switch material needs to be manually taken down. The unloading mechanism 5 of the case is cooperatively designed with the structure of the clamp 2, both of which are simple in structure and do not need more mechanism linkage for unloading, so that the whole unloading process is simple and efficient, and the stability and accuracy of unloading can be effectively guaranteed.

[0034] As Figure 1 , Figure 2As shown, the second conveying mechanism 6 of the case includes a second driving roller 61, a second motor 62, a second driven roller 63, and a second conveying belt 64. The second motor 62 is connected with the second driving roller 61 to drive the second driving roller 61 to rotate. The second conveying belt 64 is sleeved between the second driving roller 61 and the second driven roller 63 and can circulate between them. The second motor 62 provides a power source to drive the second driving roller 61 to rotate. The first driven roller 13 cooperates with the second driving roller 61 to support and guide the movement of the second conveying belt 64. In specific implementation, the second motor 62 is a speed-regulating motor to adjust the conveying speed of the second conveying mechanism 6 as required. Second baffles 65 are arranged on both sides of the second conveying belt 64. The second baffles 65 are arranged on both sides of the upper end of the second conveying belt 64 to prevent the handle knob switch from falling off the second conveying belt 64 during transmission.

[0035] As shown, Figures 1 to 4 The rotating mechanism 4 of the case includes a rotating shaft 41, a third motor 42, a third cylinder 43, and an extension frame 44. The upper end of the rotating shaft 41 is drivingly connected with the third motor 42 to facilitate rotation under the drive of the third motor 42. The side of the rotating shaft 41 is connected to the side wall of the third motor 42 through a bearing 45. The extension frame 44 includes a second fixed seat 441, a support rod 442 connected to the second fixed seat 441, and a linear bearing 443 movably connected to the support rod 442. The third cylinder 43 is connected to the upper end of the support rod 442. The third motor 42 is connected to the linear bearing 443 through a connecting plate 46. The end of the third cylinder 43 is connected to the side wall of the third motor 42.

[0036] As described above, the rotating mechanism 4 of the case realizes efficient, accurate, and multi-grade automatic detection of the handle knob switch, ensuring the continuity and stability of the detection and rotation process, and improving the detection efficiency and quality. The extension frame 44 provides stable support and guidance for the third motor 42 and the rotating shaft 41, ensuring that the rotating shaft 41 can accurately insert and exit the handle knob switch, and ensuring that the third motor 42 and the rotating shaft 41 do not deviate or shake during up and down movement, improving the stability of the operation. The design of the linear bearing 443 ensures that the third motor 42 and the rotating shaft 41 can move smoothly along the support rod, improving the accuracy of inserting and pulling out the handle knob switch. In specific implementation, the third motor 42 is drivingly connected with the rotating shaft 41 through a belt (not shown in the figure). The third cylinder 43 is arranged to drive the third motor 42 to move up and down along the support rod 442, thereby driving the rotating shaft 41 to move up and down. In specific implementation, the end of the rotating shaft 41 is provided with a clamping groove matched with the handle knob switch. The end of the rotating shaft 41 is inserted into the handle part of the handle knob switch and drives the handle to rotate.

[0037] When the handle knob switch is placed on the clamp 2 by artificial, the detection mechanism 3 is started, at the same time, the rotating mechanism 4 is also started to cooperate with the detection mechanism 3 to detect. Specifically, the third cylinder 43 drives the third motor 42 and the rotating shaft 41 to descend synchronously, the rotating shaft 41 is clamped into the handle knob switch, the third motor 42 drives the rotating shaft 41 to rotate, and the rotating shaft 41 rotates in the forward direction or the reverse direction, and the rotating shaft 41 rotates multiple times to test different gears of the handle knob switch, and when the test is completed, the third cylinder 43 drives the third motor 42 and the rotating shaft 41 to ascend synchronously.

[0038] Preferably, the third motor 42 is a stepping motor, the number of rotations and the angle of the rotating shaft 41 are controlled by setting a program, and different gears of the knob switch are detected respectively to adapt to different models of the knob switch. In specific implementation, the bearing 443 is provided with multiple bearings to assist the rotating shaft 41 to rotate, the bearing 433 plays a role of supporting the rotating shaft 41, and the rotating shaft 41 rotates stably and accurately. At the same time, the bearing 433 connects the rotating shaft 41 and the third motor 42, so that the rotating shaft 41 and the third motor 42 can ascend and descend synchronously.

[0039] Further, as shown in Figure 1 、 Figure 2 , in order to ensure the safety of personnel when taking and placing the handle knob switch on the clamp 2, and prevent personnel from being accidentally injured, the sensing mechanism 8 is further provided on the rack 100, the sensing mechanism 8 includes the thermal infrared human body sensor 81 symmetrically arranged on the left and right sides of the detection device 200, and the thermal infrared human body sensor 81 is arranged between the detection device 200 and the first conveying mechanism 1. That is, when the thermal infrared human body sensor 81 senses the taking and placing action of personnel, the detection device 200 will not start, and after the thermal infrared human body sensor 81 senses that the hands of personnel are moved away from the detection device 200, the detection device 200 starts to work.

[0040] Continuing as shown in Figure 1 、 Figure 2 , the central control system 7 of the present case includes the control panel 71, and the control panel is used for debugging and control to adapt to the detection requirements of different models of the knob switch

[0041] Further, as shown in Figure 1 、 Figure 2 , the installation table 101 is further provided with the material frame 9 located in front of the first conveying mechanism 1. The material frame 9 is used for temporarily storing the handle knob switch materials conveyed by the first conveying mechanism 1, and prevents the materials on the first conveying mechanism 1 from being stacked too much to affect the work of the first conveying mechanism 1.

[0042] The complete working principle of the handle knob switch testing machine of the present case is as follows:

[0043] The device is in standby state, waiting for the material to enter the detection process. The first conveying mechanism 1 conveys the handle knob switch material assembled in the previous process from the material frame 9 to the corresponding clamp 2 position of the detection device 200. The material frame 9 is used to temporarily store the handle knob switch material conveyed by the first conveying mechanism 1, preventing the material on the first conveying mechanism 1 from stacking too much, ensuring smooth transmission. The personnel take out the material from the material frame 9 and place it on the clamp 2, preparing for detection. The thermal infrared human sensor 81 monitors the personnel's actions in real time, ensuring that the detection device 200 does not start when the personnel take and place the material, ensuring operation safety. When the sensor detects that the personnel's hands move away from the detection device 200, the first cylinder 32 of the two symmetrically arranged detection mechanisms 3 starts, driving the detection head 33 to move forward, so that the four conductive needles 34 are inserted into different electrical interfaces of the handle knob switch on the clamp 2. After the conductive needles 34 are inserted, the detection mechanism 3 starts to detect, evaluating the electrical performance of the handle knob switch. Each conductive needle 43 is responsible for a specific electrical interface, ensuring that all interfaces can be strictly detected. The third cylinder 43 of the rotating device 4 starts, driving the third motor 42 and its attached components to move downward along the support rod 442, so that the rotating shaft 41 end is inserted into the handle part of the handle knob switch on the clamp 2. The third motor 42 starts, driving the rotating shaft 41 to rotate under program control, bringing the handle knob switch to multi-position detection. According to the set program, the number of rotations and the angle of the rotating shaft are controlled, and different positions of the knob switch are detected respectively. After detection is completed, the third cylinder 43 is started again, driving the third motor 42 and its attached components to move upward along the support rod 442, so that the rotating shaft is pulled out of the handle knob switch. When the detection is qualified, the second cylinder 51 starts the retraction action, driving the movable seat 52 and the bottom plate 53 to move backward, so that the bottom plate is detached from the insertion slot 23. At this time, the positioning hole 21 is connected with the discharging hole 22, and because there is no support of the bottom plate 53, the material in the positioning hole 21 automatically falls into the discharging hole 22, and finally falls into the second conveying mechanism 6, completing the discharging. When the detection is unqualified, the second cylinder 51 does not retract, and the bottom plate 53 remains in the insertion slot 23, and the unqualified material needs to be taken out manually. The above process is repeated to ensure that each handle knob switch can be strictly detected, and the qualified products are conveyed out of the rack by the second conveying mechanism 6, and the unqualified products are handled by manual.

[0044] The handle knob switch testing machine of the present case realizes the full-process automation operation from material feeding, detection, discharging to safety control. Not only simplifies the detection process of handle knob switch, but also greatly improves the stability and accuracy of detection. Through precise control and efficient connection, the handle knob switch testing machine of the present case ensures the smoothness and efficiency of the whole detection process, significantly improves the assembly quality and production efficiency of the product. In addition, the flexible configuration of the mechanism structure such as clamp 2, detection mechanism 3 and the flexible configuration options of the number of detection devices 200 make the equipment adapt to handle knob switches of various specifications and models and different detection efficiency requirements, meet the diversified needs of different users.

[0045] As above, the present case protects a handle knob switch testing machine, and all technical solutions identical or similar to the present case shall be shown to fall within the protection scope of the present case.
