The knob body 120 is electrically connected to the control circuit, and the knob 100 has multiple working positions that can be rotated to different angles. By rotating the knob body 120 to different working positions, different signal nodes can be triggered, thereby generating corresponding trigger signals. The control circuit is responsible for processing these trigger signals and converting them into specific control logic so that the knob 100 can achieve different control effects.

[0003] After the knob 100 is manufactured, it needs to be tested, such as the response speed of the control circuit after the knob body 120 is rotated to one of the working positions, to ensure the real-time and smooth control of the knob and avoid delays or stuttering.

[0004] Currently, when testing the knob 100, the knob body 120 is mostly rotated manually to different working positions, and the conduction status of the control circuit is determined by the controller. However, manually rotating the knob body 120 is labor-intensive and inefficient.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0046] Please see Figure 1 The knob 100 includes a housing 110, a control circuit disposed inside the housing 110, and a knob body 120 rotatably disposed on the housing 110. The knob body 120 is electrically connected to the control circuit, and the knob 100 has multiple working positions that can be rotated to different angles. Currently, when testing the knob 100, the knob body 120 is mostly rotated manually, which results in high labor intensity and low work efficiency for the workers. Therefore, this embodiment aims to propose a knob testing device to improve the testing efficiency of the knob 100 and reduce the labor intensity of the workers.

[0047] Specifically, please refer to Figures 2 to 6 The knob detection device includes a support part 1, a rotating part 2, and a detection part. The support part 1 supports and locks the housing 110; the rotating part 2 is connected to the knob body 120 and drives the knob body 120 to rotate sequentially to different working positions; the detection part is electrically connected to the control circuit to detect the conduction state of the control circuit when the knob body 120 is in different working positions. Preferably, the detection part is a PIC controller (Programmable Interrupt Controller) from the prior art.

[0048] It is understandable that by placing the knob 100 on the support part 1 and electrically connecting the detection part to the control circuit of the knob 100, the knob body 120 is rotated sequentially to different working positions by the rotating part 2, so that the detection part can detect the conduction status of the control circuit. With this setting, the rotation part 2 can replace manual rotation, which can reduce the labor intensity of the workers and ensure the detection efficiency of the knob 100.

[0049] It should be noted that the conduction state of the control circuit includes, but is not limited to, whether the circuit is conducting or not, and the response speed of the control circuit after the knob body 120 is rotated to one of the working positions, etc., which are not specifically limited here.

[0050] In this embodiment, the supporting part 1 includes a platform 11 and a pushing mechanism 12. The platform 11 has a through hole 111 through which the knob body 120 passes. The pushing mechanism 12 is spaced apart from the platform 11 and is used to push the housing 110 so that the housing 110 remains in contact with the platform 11. It can be understood that when the operator passes the knob body 120 through the through hole 111, the pushing mechanism 12 can lock the knob 100 onto the platform 11, thereby preventing the knob 100 from shifting during the testing process. This ensures the accuracy of the docking between the knob body 120 and the rotating part 2, and thus ensures the accuracy of the knob 100 during the testing process.

[0051] Preferably, the platform 11 and the pushing mechanism 12 are arranged vertically. It can be understood that when the knob 100 is placed, the knob 100 is placed upside down on the platform 11, that is, the knob body 120 is set downwards, and the knob body 120 is passed through the through hole 111. Under the cooperation of the pushing mechanism 12 and the platform 11, the knob 100 can be limited in the vertical direction to lock the knob 100.

[0052] The pushing mechanism 12 includes a driving member 121 and a pushing member 122. The pushing member 122 is disposed at the driving end of the driving member 121, and the driving member 121 is used to drive the pushing member 122 to move closer to or away from the housing 110. It is understood that the driving member 121 is preferably a linear drive structure in the prior art, such as a cylinder. The piston rod of the cylinder is arranged vertically as the driving end, and the pushing member 122 is disposed on the piston rod of the cylinder. Under the action of the piston rod, the pushing member 122 can be pushed closer to or away from the housing 110, thereby completing the locking and unlocking of the knob 100. The pushing member 122 is preferably rod-shaped, coaxially arranged with the piston rod, and has an elastic pad at the end that abuts against the knob 100 to prevent rigid contact between the pushing member 122 and the knob 100 when locking the knob 100.

[0053] Furthermore, the support unit 1 also includes a positioning member 13, which is detachably mounted on the platform 11. The positioning member 13 has a positioning groove 131 that is adapted to engage with the housing 110, so that the through hole 111 is coaxially arranged with the knob body 120. It is understood that when testing different models of knobs 100, different models of positioning members 13 are selected, and the positioning member 13 is installed on the platform 11 using detachable connectors such as bolts. The through hole 111 is placed in the positioning groove 131. Under the action of the positioning groove 131, the rotating body and the through hole 111 can be coaxially arranged, thereby enabling the positioning of different models of knobs 100 and improving the applicability of the knob testing device. In addition, under the action of the positioning groove 131, the rotation of the knob body 120 is prevented from causing the housing 110 to rotate synchronously, thus ensuring the accuracy of the knob body 120 during rotation.

[0054] In this embodiment, the rotating part 2 includes a rotating component 21 and an angle detection component 22. The rotating component 21 has a rotating end that rotates around its own axis, and the rotation axis of the rotating end coincides with the rotation axis of the knob body 120. The angle detection component 22 is disposed at the rotating end and electrically connected to the rotating component 21 to control the rotation angle of the rotating end. It is understood that the rotating component 21 is preferably a stepper motor in the prior art. The rotating shaft of the stepper motor serves as the rotating end of the rotating component 21 and can be connected to the knob body 120 to drive the knob body 120 to rotate around its own axis. In addition, the angle detection component 22 is preferably an encoder in the prior art. The encoder and the stepper motor can be combined to form a closed-loop control system. The encoder monitors the angle or speed of the stepper motor in real time and feeds the information back to the controller. The controller compares the preset target with the feedback information and adjusts the output pulse signal to correct the actual operating state of the stepper motor, thereby enabling precise motion control of the rotation angle of the rotating body to control the knob body 120 to rotate accurately to different working positions and improve the accuracy of detection.

[0055] Furthermore, the end of the knob body 120 facing away from the housing 110 has a notch 1210; the rotating end has a locking groove 211 that is adapted to engage with the knob body 120. It can be understood that, under the action of the notch 1210 and the locking groove 211, the rotating end and the knob body 120 can be ensured to rotate synchronously, thereby further ensuring the positional accuracy of the knob body 120 during rotation. Preferably, the notch 1210 is a flat notch 1210.

[0056] In this embodiment, the detection unit has at least two ejector pins 3, and the control circuit has at least two terminals 130, with each ejector pin 3 corresponding to each terminal 130. The knob detection device also includes a moving part 4, which is used to move all ejector pins 3 simultaneously closer to or further away from their corresponding terminals 130. Under the action of the moving part 4, each ejector pin 3 can be brought into contact with its corresponding terminal 130, thereby connecting the detection circuit on the detection unit with the control circuit to detect the conduction state of the control circuit. After detection, the ejector pins 3 can be separated from the terminals 130 by the moving part, allowing the operator to remove the knob 100. The entire process does not require manual connection of the detection circuit and control circuit, resulting in low human intervention and further improving the detection efficiency of the knob 100.

[0057] Specifically, the moving part 4 includes a moving member 41 and a base 42. The moving member 41 has a moving end that can move closer to or further away from the terminal 130. The base 42 is disposed on the moving end, and all the ejector pins 3 are fixedly fixed to the base 42 at intervals along a preset direction. It is understood that the moving member 41 is preferably a linear motion cylinder in the prior art. The piston rod of the linear motion cylinder serves as the moving end of the moving member 41, which can move closer to or further away from the terminal 130, fixing all the ejector pins 3 side by side on the base 42. Under the action of the moving member 41, the ejector pins 3 can be moved to a position that mates with the terminal 130. In addition, the fixed connection method can ensure that the ejector pins 3 remain in the initial position after a long period of testing, thereby improving the accuracy of testing. The fixed connection method is preferably a snap-fit ​​connection or other similar connection method, which will not be described in detail here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
