Description

Technical Field

[0001] This utility model belongs to the field of sensor assembly technology, specifically relating to an O-ring feeding and detection mechanism for sensor assembly. Background Technology

[0002] In the field of modern sensor manufacturing, O-rings are widely used in various sensor products as important sealing elements, playing a crucial role in preventing liquid and gas leakage and dust prevention. Their assembly quality directly affects the performance and service life of the sensor.

[0003] Currently, in the sensor assembly process, the loading of O-rings relies on manual operation. Workers need to manually place the O-rings in the designated positions and manually press them onto the sensor. Before the O-rings are pressed and installed, defect detection is required. Existing detection methods mostly rely on manual visual inspection, where workers use their experience and eyesight to judge whether the O-rings are installed correctly and whether there is any damage. This detection method is greatly affected by human factors, and the accuracy and reliability of the detection results are low. It is easy to miss or misjudge problems. Moreover, manual inspection is slow and cannot match the pace of automated production lines, which greatly reduces assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an O-ring feeding and detection mechanism for sensor assembly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an O-ring feeding and detection mechanism for sensor assembly, comprising:

[0006] A vertical frame is provided, with a horizontal frame connected to the top of the vertical frame. An X-axis servo screw linear module is connected to the horizontal frame. A fixed plate is provided on the X-axis moving slide of the X-axis servo screw linear module. A Z-axis servo screw linear module is connected to the fixed plate. A mounting frame is provided on the Z-axis moving slide of the Z-axis servo screw linear module, and a pre-compression component for pressing the O-ring seal is provided on the mounting frame.

[0007] A CCD vision detector is mounted on the surface of a fixed plate and is used to detect and confirm whether the O-ring is installed in place.

[0008] Preferably, the pre-compression assembly includes a pressure frame connected to the surface of the mounting frame, and a pressure head connected to the bottom of the pressure frame.

[0009] Preferably, a detection frame is connected to the fixed plate, and the CCD vision detector is mounted on the detection frame.

[0010] Preferably, a focusing ring is installed on the surface of the detection frame and at the bottom of the CCD vision detector.

[0011] Preferably, the stand is equipped with a cable chain at the top and a storage box at the bottom.

[0012] Preferably, a slide rail is connected to the crossbar, and one end of the fixing plate is slidably connected to the slide rail.

[0013] Preferably, the bottom of the support frame is connected to a mounting base.

[0014] Preferably, a distance sensor is provided at the bottom of the pressure frame and on one side of the pressure head.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The mechanism is equipped with X-axis and Z-axis servo lead screw linear modules, which can realize fast and accurate displacement control. In the O-ring pressing process, the pre-pressing component can be quickly moved to the designated position. The automated operation mode can work continuously and stably, effectively improving the overall production efficiency and meeting the needs of large-scale production.

[0017] (2) In terms of inspection, the CCD vision detector can accurately determine whether the O-ring is installed in place by analyzing the O-ring image. It can also detect whether the O-ring has minor defects such as deformation or damage. This inspection method is not affected by human factors and avoids the problems of missed detection and misjudgment caused by insufficient experience and visual fatigue during manual inspection. It ensures the accuracy and reliability of the inspection results, thereby improving the overall quality of sensor products, greatly increasing the inspection speed, and reducing the waiting time in the production process.

[0018] (3) The design of the pressure frame and pressure head in the pre-compression assembly can perform stable compression operation on the O-ring. The pressure head can accurately install the O-ring onto the sensor according to the set pressure and stroke, ensuring the installation quality of the O-ring. At the same time, the distance sensor set on one side of the bottom of the pressure frame can monitor the distance between the pressure head and the sensor or O-ring in real time, further ensuring the accuracy of the compression process and avoiding damage to the O-ring or loose installation due to excessive or insufficient pressure.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-2 The sensor assembly O-ring feeding and detection mechanism shown includes:

[0024] A vertical frame 1 is provided, and a horizontal frame 2 is connected to the top of the vertical frame 1. An X-axis servo screw linear module 3 is connected to the horizontal frame 2. A fixed plate 4 is provided on the X-axis moving slide of the X-axis servo screw linear module 3. A Z-axis servo screw linear module 5 is connected to the fixed plate 4. A mounting frame 6 is provided on the Z-axis moving slide of the Z-axis servo screw linear module 5, and a pre-compression component for pressing the O-ring seal is provided on the mounting frame 6.

[0025] CCD vision detector 7, which is disposed on the surface of fixed plate 4, is used to detect and confirm whether the O-ring is installed in place.

[0026] The pre-compression assembly includes a pressure frame 8, which is connected to the surface of the mounting frame 6. A pressure head 9 is connected to the bottom of the pressure frame 8. The mounting frame 6 serves as a carrier, providing a stable installation foundation for the pressure frame 8. The pressure frame 8 is firmly connected to the surface of the mounting frame 6, ensuring that there will be no loosening or displacement during the entire operation, and ensuring the stable operation of the pressure head 9.

[0027] The fixing plate 4 is connected to the detection frame 10, and the CCD vision detector 7 is installed on the detection frame 10.

[0028] A focusing ring 11 is installed on the surface of the detection frame 10 and at the bottom of the CCD vision detector 7.

[0029] The top of the support frame 1 is equipped with a cable chain 12 and the bottom is equipped with a storage box 13. The cable chain 12 at the top of the support frame 1 is used to store and protect the cables during the operation of the equipment. With the movement of the X-axis and Z-axis, the cable chain 12 can bend and extend flexibly to ensure that the cables are not subjected to excessive pulling or friction, and to ensure that the electrical connection of the equipment is stable and reliable. The storage box 13 at the bottom of the support frame 1 is used to store tools, spare parts and other items, which are convenient for operators to access during equipment maintenance and debugging.

[0030] The crossbar 2 is connected to a slide rail 14. One end of the fixed plate 4 is slidably connected to the slide rail 14. The slide rail 14 provides a stable guide for the movement of the fixed plate 4. When the X-axis servo screw linear module 3 drives the fixed plate 4 to move, the slide rail 14 restricts the movement direction of the fixed plate 4, so that it can only slide smoothly along the direction of the slide rail 14, avoiding the fixed plate 4 from deviating, shaking or getting stuck during the movement.

[0031] The bottom of the support frame 1 is connected to a mounting base 15, which is designed with mounting holes. The entire mechanism can be easily and securely installed in the designated working position through the mounting holes.

[0032] A distance sensor 16 is provided at the bottom of the pressure frame 8 and on one side of the pressure head 9. The distance sensor 16 can monitor the distance between the pressure head 9 and the O-ring or the sensor installation position in real time.

[0033] The sensor is equipped with an O-ring feeding and detection mechanism. The mechanism is supported by a vertical frame 1. The horizontal frame 2 connected to the top of the vertical frame 1 provides an installation platform for the X-axis servo lead screw linear module 3. When the X-axis servo lead screw linear module 3 is working, the motor inside the X-axis servo lead screw linear module 3 drives the lead screw to rotate, causing the X-axis moving slide to move linearly along the lead screw. This, in turn, drives the fixed plate 4 mounted on the X-axis moving slide to move precisely in the X-axis direction. The Z-axis servo lead screw linear module 5 on the fixed plate 4 is also driven by a motor to control the Z-axis moving slide to move up and down in the Z-axis direction. The mounting frame 6 moves with the Z-axis moving slide. In this way, through the coordinated movement of the X-axis and Z-axis servo lead screw linear modules 5, the position of the pre-pressing component on the mounting frame 6 can be precisely controlled, and the precise positioning of the O-ring feeding and pressing position can be achieved.

[0034] The CCD vision detector 7 is mounted on the inspection frame 10, which is connected to the fixed plate 4. After the O-ring is manually placed to the designated position, the CCD vision detector 7 starts working. The focusing ring 11 is used to adjust the focal length of the CCD vision detector 7 so that the O-ring presents a clear image within the imaging range of the CCD vision detector 7. The CCD vision detector 7 receives the light reflected from the O-ring, converts the light signal into an electrical signal, and then generates a digital image after a series of processing and conversions. The computer image processing system analyzes these digital images and, through preset algorithms and standards, determines whether the installation position of the O-ring is accurate and whether the O-ring has defects such as deformation or damage. If the O-ring is detected to be improperly installed, the system will issue a corresponding signal to notify the operator to handle it or start the subsequent rejection procedure for defective products.

[0035] When a qualified O-ring is placed on the pressing position on the sensor, the pressure frame 8 in the pre-pressing assembly is connected to the surface of the mounting bracket 6. After the mounting bracket 6 moves to the designated position, the pressure head 9 at the bottom of the pressure frame 8 moves downward under the drive of the Z-axis servo lead screw linear module 5. During the pressing of the O-ring, the distance sensor 16 monitors the distance between the pressure head 9 and the O-ring or the sensor mounting position in real time. When the distance reaches the set value, the pressure head 9 stops descending and maintains a certain pressure to accurately press the O-ring onto the sensor, ensuring that the O-ring is installed tightly and plays a good sealing role.

[0036] The working principles of other auxiliary components: The cable carrier 12 at the top of the upright frame 1 is used to store and protect cables during equipment operation. With the movement of the X and Z axes, the cable carrier 12 can flexibly bend and extend, ensuring that the cables are not subjected to excessive pulling or friction, and guaranteeing stable and reliable electrical connections. The storage box 13 at the bottom of the upright frame 1 is used to store tools, spare parts, and other items, making them convenient for operators to access during equipment maintenance and debugging. The slide rail 14 connected to the cross frame 2 is slidably connected to one end of the fixed plate 4, providing stable guidance for the movement of the fixed plate 4, enhancing the smoothness of X-axis movement, and further improving the accuracy of loading and inspection. The mounting base 15 fixes the entire mechanism to the workbench, increasing the stability of the equipment, reducing vibration during operation, and ensuring the accuracy of inspection and assembly work.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
