Description

Technical Field

[0001] The utility model relates to the technical field of electric cooker detection, in particular to an electric cooker button convex height detection tool. Background Art

[0002] Electric rice cookers are also called electric pots or rice cookers. They are cookers that convert electrical energy into internal energy. They are easy to use, clean and hygienic, and have multiple functions such as steaming, boiling, stewing and simmering food. Common electric rice cookers are divided into three categories: automatic heat preservation type, timed heat preservation type and new microcomputer controlled type. Now they have become daily household appliances. The invention of electric rice cookers has reduced the time many families spend on cooking. Electric rice cookers need to be tested during production.

[0003] For example, the "automatic detection equipment for an electric rice cooker" with the publication number "CN220040615U" includes a frame, on which are provided a fixing device, a camera recognition device and a hand clamping device; the fixing device is used to fix the electric rice cooker; the camera recognition device is used to photograph the electric rice cooker and identify whether the photographed image contains the power slot position of the electric rice cooker; the hand clamping device includes an XYZ moving mechanism and a hand clamping mechanism, and the hand clamping mechanism is arranged at the Z-moving end of the XYZ moving mechanism; the present application utilizes the camera recognition device to first identify the power slot position of the electric rice cooker in the photographed image, and then acts on the position of the power cord through the XYZ moving mechanism and the hand clamping mechanism, thereby completing the automatic power-on and power-off operations of the electric rice cooker, thereby completing subsequent detection work related to input parameters such as input power and input current of the electric rice cooker, which can reduce manual labor intensity and improve detection efficiency.

[0004] However, the above patent does not detect the rice cooker buttons. If the rice cooker buttons are empty or sunken, the production quality of the rice cooker will be affected. In view of this, we propose a tool for detecting the height of the convex hull of the rice cooker buttons. Utility Model Content

[0005] The utility model aims to provide a tool for detecting the height of a convex hull of a rice cooker button to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tool for detecting the height of a convex bump of a rice cooker button, comprising: a device body, a detection module is arranged on the device body, a mechanical arm is arranged on the detection module, and a height detection mechanism is arranged on the mechanical arm;

[0009] Preferably, a reset mechanism is provided on the robotic arm, and the reset mechanism comprises: a sleeve, which is fixedly connected to the bottom of the robotic arm, the inner wall of the sleeve is slidably connected with a sleeve rod ejector, the bottom end of the sleeve rod ejector extends into the interior of the hollow tube, the top end of the sleeve rod ejector is fixedly connected with a reset spring, and the top end of the reset spring is fixedly connected to the inner wall of the sleeve.

[0010] Preferably, the top end of the stylus is fixedly connected with a bracket, the bracket is arranged in an inverted "U" shape, and is located directly below the ejector pin of the sleeve rod. The hollow tube is driven upward by an electric telescopic rod. When the ejector pin of the sleeve rod contacts the bracket, the ejector pin of the sleeve rod pushes the bracket downward, and the bracket drives the stylus to move, thereby causing the stylus to drive the slider to slide along the slide groove, thereby resetting the stylus to facilitate subsequent detection operations.

[0011] Preferably, the inner wall of the hollow tube is provided with two slide grooves opposite to each other, the outer wall of the stylus is fixedly connected with two sliders, and the two sliders are slidably connected with the two slide grooves respectively, and the sliders are driven by the stylus to slide along the inner wall of the slide groove, so as to facilitate the movement of the stylus.

There are two electric telescopic rods, two top plates and two buffer springs, which are respectively located on the left and right sides of the hollow tube. When the electric telescopic rod drives the hollow tube to fit the rice cooker, the pressure of the electric telescopic rod can be buffered by the provided buffer spring.

[0013] Preferably, the bottom ends of the hollow tube and the stylus are fixedly connected with a protective film, and the protective film can protect the contact surface between the hollow tube and the stylus and the rice cooker, thereby avoiding scratches on the surface of the rice cooker, further improving the production quality of the rice cooker.

[0015] 1. The top plate is driven down by starting the electric telescopic rod, and the top plate drives the mounting plate to move, and the mounting plate drives the hollow tube to move. When the bottom of the hollow tube is in contact with the surface of the rice cooker, the convex bulge of the rice cooker button pushes the stylus upward, and the stylus drives the infrared sensor to move. At the same time, the signal receiving panel receives the signal. At this time, the vertical movement distance of the infrared sensor is the height of the button bulge, so that it can detect whether the rice cooker button is stepped on or sunken, thereby improving the production quality of the rice cooker. On the contrary, the hollow tube is driven upward by the electric telescopic rod. When the sleeve rod ejector pin contacts the bracket, the sleeve rod ejector pin pushes the bracket downward, and the bracket drives the stylus to move, so that the stylus drives the slider to slide along the slide groove, so that the stylus is reset, which is convenient for subsequent detection operations.

[0016] 2. When the electric telescopic rod drives the hollow tube to fit the electric rice cooker, the pressure of the electric telescopic rod can be buffered by the provided buffer spring, and the contact surface between the hollow tube and the stylus and the electric rice cooker can be protected by the provided protective film, thereby avoiding scratches on the surface of the electric rice cooker, and further improving the production quality of the electric rice cooker.
