[0002] In the manufacturing sector, many products require rigorous testing, especially during the assembly process, where the assembly results need to be assessed to accurately determine whether the product is assembled correctly.

[0003] Common height detection devices in existing technologies, such as digital height gauges, have low detection accuracy, making it difficult to meet the accuracy requirements of assembling non-standard products. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an automated detection device to solve the technical problem of low detection accuracy of existing detection devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated detection device, comprising: A transmission mechanism is used to move the item to be inspected to the inspection position; A testing mechanism is used to measure the height of the object to be tested transmitted by the transmission mechanism; The detection mechanism includes a detection plate, a displacement sensor disposed on the detection plate, a spindle disposed on the detection plate and coaxially disposed with the displacement sensor, and a telescopic cylinder for driving the detection plate to move up and down.

Detailed Implementation

[0019] like Figures 1 to 4 As shown, this embodiment proposes an automated detection device, which includes a transmission mechanism 1 and a detection mechanism 2. The transmission mechanism 1 can be used to move the workpiece 3 to be detected to the detection position, and the detection mechanism 2 can be used to measure the height of the workpiece 3 conveyed by the transmission mechanism 1. Specifically, the detection mechanism 2 includes a detection plate 21, a displacement sensor 22, a spindle 23, and a telescopic cylinder 24. The displacement sensor 22 is disposed on the detection plate 21, and the spindle 23 is disposed on the detection plate 21 and coaxially disposed with the displacement sensor 22. In addition, the transmission mechanism 1 is provided with a positioning shaft 25, and the workpiece 3 to be detected is sleeved on the positioning shaft 25. In this way, the workpiece 3 to be tested can be conveyed to the position of the testing mechanism 2 for testing through the transmission mechanism 1. The mandrel 23 of the testing mechanism 2 abuts against the positioning shaft 25, and the displacement sensor 22 abuts coaxially with the mandrel 23, so that the height of the workpiece to be tested can be accurately measured, which effectively improves the testing accuracy. The detection plate 21 is raised and lowered by the telescopic cylinder 24. The displacement sensor 22 deforms when subjected to the pressure. When the bottom end face of the detection plate 21 contacts the end face of the workpiece 3 to be tested, the displacement sensor 22 detects the height value of the workpiece 3 to be tested based on the displacement change value measured by the deformation. It is simple and efficient.

[0020] In this application, the working principle of the detection device is as follows: When the height of the workpiece 3 needs to be detected, the transmission mechanism 1 starts working. At this time, the workpiece 3 is accurately placed on the positioning shaft 25 on the transmission mechanism 1, and the transmission mechanism 1 smoothly moves the workpiece 3 to the detection position. Then, the telescopic cylinder 24 is activated, which drives the detection plate 21 to slowly descend. The mandrel 23 on the detection plate 21 also descends and abuts against the positioning shaft 25. Since the displacement sensor 22 is coaxially set with the mandrel 23, the displacement sensor 22 will be subjected to corresponding resistance force and deform accordingly during the process of the mandrel 23 abutting against the positioning shaft 25. As the detection plate 21 continues to descend, when the bottom end face of the detection plate 21 contacts the end face of the workpiece 3, the displacement sensor 22 measures the displacement change value according to its own deformation. By analyzing and processing the displacement change value, the height value of the workpiece 3 can be accurately detected. The whole detection process is simple, efficient and highly accurate.

[0021] Further, please refer to Figure 1 and Figure 2 As shown, the detection plate 21 is also equipped with a mounting plate 26, which is mounted on the telescopic cylinder 24. Thus, by providing the mounting plate 26, the telescopic cylinder 24 and the detection plate 21 are securely connected, ensuring that the detection plate 21 remains stable during the lifting and lowering process driven by the telescopic cylinder 24, without any shaking or deviation, thereby guaranteeing the accuracy of the detection.

[0022] Preferably, the mounting plate 26 and the detection plate 21 are integrally formed. The integral forming design makes the connection between the mounting plate 26 and the detection plate 21 tighter and more secure, reduces the use of connecting parts, lowers the probability of detection device failure due to loose or damaged connecting parts, and improves the overall reliability and stability of the detection device.

[0023] Further, please refer to Figure 2 and Figure 3 As shown, the detection plate 21 has a fixing hole 211 for fixing the displacement sensor 22. In addition, the detection plate 21 also has a through hole 212, which allows one end of the displacement sensor 22 to pass through and abut against the mandrel 23. In this way, by setting the fixing hole 211, the displacement sensor 22 can be accurately fixed at a designated position on the detection plate 21, preventing the displacement sensor 22 from shifting during operation and affecting the detection accuracy. By setting the through hole 212, a channel is provided for the abutment between the displacement sensor 22 and the mandrel 23, so that the displacement sensor 22 can accurately sense the displacement change of the mandrel 23, and thus accurately measure the height of the workpiece 3 to be tested.

[0024] Further, please refer to Figure 2 and Figure 4 As shown, a spring 27 is also fitted onto the mandrel 23. Meanwhile, a stepped hole 213 is formed on the detection plate 21, and the spring 27 is disposed within the stepped hole 213. One end of the spring 27 abuts against the mandrel 23, and the other end abuts against the detection plate 21. Thus, by incorporating the spring 27, a buffering and resetting function is achieved. Specifically, during the detection process, when the mandrel 23 experiences a pressure drop, the spring 27 is compressed, absorbing some of the pressure and preventing excessive impact between the mandrel 23 and the detection plate 21, thus protecting the various components of the detection device. After the detection is completed, the elasticity of the spring 27 allows the mandrel 23 to quickly return to its initial position, preparing for the next detection, thereby improving the working efficiency and stability of the detection device.

[0025] Further, please refer to Figure 1As shown, the displacement sensor 22 also has a connector 221 for electrical connection to an external terminal device. By using connector 221, the displacement sensor 22 can transmit measured displacement change values ​​and other data to an external terminal device, such as a computer or controller, in real time. The external terminal device can further process and analyze this data, such as converting the displacement change values ​​into the height value of the part to be inspected, and storing, displaying, or judging according to preset standards, thereby achieving automated processing and management of the inspection results and improving the level of intelligence in the inspection work.

[0026] Further, please refer to Figure 1 As shown, the detection plate 21 has an opening 214 at the contact position between the displacement sensor 22 and the spindle 23. Through this opening 214, the contact between the displacement sensor 22 and the spindle 23 can be easily observed. During the detection process, the staff can directly see through the opening 214 whether the two are accurately contacting each other, and whether there are any abnormalities in the contact process, such as whether the displacement sensor 22 is loose or whether the spindle 23 is offset, so as to facilitate timely detection and problem solving and ensure the smooth progress of the detection work.

[0027] Further, please refer to Figure 2 As shown, the detection mechanism 2 also includes a base 28, on which the telescopic cylinder 24 is mounted. By setting the base 28, a stable support platform is provided for the telescopic cylinder 24, enabling it to remain stable during operation and preventing it from shaking due to its own vibration or external factors. This ensures the smoothness of the lifting and lowering of the detection plate 21, thereby improving the accuracy of the detection.

[0028] Further, please refer to Figure 1 As shown, the transmission mechanism 1 includes a hydraulic cylinder 11 and a slider 12. The slider 12 is located at the movable end of the hydraulic cylinder 11, and the positioning shaft 25 is mounted on the slider 12. By controlling the extension and retraction of the hydraulic cylinder 11, the slider 12 can be moved smoothly in the horizontal direction, thereby accurately moving the workpiece 3 to the detection position. The slider 12 facilitates the installation of the positioning shaft 25 and allows for easy adjustment of its position to accommodate the detection requirements of workpieces of different specifications.

[0029] Furthermore, such as Figure 1As shown, the testing device also includes a base plate 4, on which both the testing mechanism 2 and the transmission mechanism 1 are mounted. By setting up the base plate 4, a unified installation platform is provided for the entire testing device, integrating the testing mechanism 2 and the transmission mechanism 1 together. This makes the structure of the testing device more compact and reasonable, facilitating installation, debugging, and maintenance. At the same time, the base plate also provides a certain degree of protection, protecting the various components of the testing device from interference and damage from the external environment.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
