Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology for liquid crystal display panels, and more specifically, to a transfer mechanism for dual pressure sensor detection. Background Technology

[0002] Currently, most automated transfer stations on the market do not use pressure sensors. The disadvantages of this method are: (1) During equipment interaction (such as placement, picking, docking), excessive pressure (overpressure) can easily lead to product damage, or insufficient pressure (not meeting the standard) can lead to interaction failure (such as not being firmly adsorbed or not being placed in place). (2) Due to the lack of real-time detection and quantification of the actual applied pressure, operators cannot accurately grasp the pressure value during the interaction process. (3) When it is necessary to change the production model of the product, due to the lack of a predetermined pressure parameter as a reference, the equipment debugging time is long, the efficiency is low, and errors are easy to occur, making it difficult to quickly adapt to the production needs of the new product. Therefore, there is an urgent need for a mechanism that can detect pressure in real time and in multiple dimensions during product transfer and quantify the pressure parameters to improve the accuracy, reliability, and changeover efficiency of equipment interaction. Utility Model Content

[0003] To address the problems in existing automated transfer stations, such as the inability to detect pressure in real time, the potential for overpressure / underpressure on products, the inability to quantify parameters, and the long turnaround times, this invention provides a transfer mechanism with dual pressure sensors. By incorporating dual pressure sensors and a corresponding elastic buffer structure, real-time detection and quantification of the pressure experienced by the product during transfer and interaction with equipment are achieved. This provides data for equipment pressure control and improves the accuracy and reliability of the interaction.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a transfer mechanism for dual pressure sensor detection, comprising: an X-direction moving module, which includes an X-direction linear module and a servo motor for driving the X-direction linear module; and a Z-direction pressure detection module, which is vertically arranged above the X-direction linear module. The Z-direction pressure detection module includes a first fixed plate, a second fixed plate, and a third fixed plate arranged parallel to each other along the Z-direction. A first pressure sensor is arranged on the upper side of the first fixed plate, and the second fixed plate is located above the first pressure sensor. First linear bearings are fixed around the second fixed plate, and a first guide post slides through the first linear bearing. The bottom end of the first guide post slides through the second fixed plate. The top of the device is fixed to the third fixing plate; the X-direction pressure detection module is set on the upper side of the third fixing plate. The X-direction pressure detection module includes a fourth fixing plate, a fifth fixing plate, and a sixth fixing plate arranged parallel to each other along the X-direction. A second pressure sensor is set in the middle of the right side of the fourth fixing plate. The fifth fixing plate is set to the right side of the second pressure sensor. A second linear bearing is fixed at the front and rear ends of the fifth fixing plate respectively. A second guide post slides through the second linear bearing. The left side of the second guide post slides through the fourth fixing plate. The right side of the second guide post is fixedly connected to the sixth fixing plate; the fixture is fixedly connected to the right side of the sixth fixing plate. The lower side of the fixture is slidably connected to the X-direction linear guide rail installed on the upper side of the third fixing plate.

[0005] Preferably, a first spring is sleeved on the outside of the first guide post, and the first spring is located between the second fixing plate and the third fixing plate.

[0006] Preferably, a second spring is sleeved on the outside of the second guide post, and the second spring is located between the fifth fixing plate and the sixth fixing plate.

[0007] Preferably, the front and rear ends of the fourth fixing plate are respectively provided with third linear bearings, and the left side of the second guide post slides through the third linear bearing and is fixed with a fixing ring.

[0008] In summary, this utility model provides a transfer mechanism with dual pressure sensor detection. The beneficial effects of this utility model are:

[0009] The transfer mechanism with dual pressure sensors described in this invention achieves positional movement of the mechanism through an X-axis movement module, monitors the pressure exerted on the product in the Z-axis direction in real time and provides overload buffering through a Z-axis pressure detection module, and monitors the lateral pressure on the product in real time and provides overload buffering through another X-axis pressure detection module. Through the coordinated operation of the dual pressure sensors, precise quantification and monitoring of the pressure (especially the Z-axis and lateral pushing forces) on the product is achieved throughout the entire process of movement, placement, picking, and other interactions with the equipment.

[0010] Pressure parameter quantification: The output signals of the first and second sensors provide operators with accurate pressure data, parameterizing the pressure state that was originally difficult to perceive.

[0011] Avoid overpressure / underpressure risks: Real-time pressure detection can promptly alert or provide feedback to the control system when pressure is abnormal, effectively preventing product damage due to excessive pressure or interaction failure due to insufficient pressure.

[0012] Reduce changeover and commissioning time: When changing to different product models, the optimal pressure parameter values ​​required for different products can be preset and stored in the system. After equipment changeover, the program can quickly recall and accurately control the pressure based on sensor feedback, eliminating the need for repeated trial and error debugging as in traditional methods, greatly improving changeover efficiency.

[0013] Provides cushioning protection: Two independent spring-guide post-linear bearing combinations provide vertical and lateral elastic compensation, allowing the suction plate to have slight displacement in the event of collision or misalignment, protecting both the product and the sensor and mechanism itself.

[0014] Enhancing the intelligence level of equipment: Integrating pressure detection into the transfer mechanism provides key process feedback information for automated production lines, laying the foundation for achieving adaptive, high-precision, and high-reliability automated production.

[0015] In summary, this mechanism has a compact structure and rich detection dimensions, enabling it to accurately quantify product interaction pressure in real time and provide effective protection, significantly improving the safety, reliability, and flexibility (rapid changeover) capabilities of automated transfer links.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] A transfer mechanism with dual pressure sensors includes: an X-direction movement module, a Z-direction pressure detection module, an X-direction pressure detection module, and a fixture 4.

[0021] The X-direction movement module includes an X-direction linear module 11 and a servo motor 12 that drives the X-direction linear module 11.

[0022] The Z-direction pressure detection module is vertically mounted on top of the X-direction linear module. The Z-direction pressure detection module includes a first fixed plate 21, a second fixed plate 22, and a third fixed plate 23 arranged parallel to each other along the Z-direction. A first pressure sensor 24 is mounted on the upper side of the first fixed plate 21, and the first sensor 24 detects the pressure value in real time. The second fixed plate 22 is located above the first pressure sensor 24. First linear bearings 25 are fixed around the second fixed plate 22, and first guide posts 26 slide through the first linear bearings 25. The bottom end of the first guide post 26 slides through the second fixed plate 22, and its top end is fixed to the third fixed plate 23.

[0023] Furthermore, a first spring 27 is sleeved on the outside of the first guide post 26, and the first spring 27 is located between the second fixing plate 22 and the third fixing plate 23. When the pressure is too high (exceeding the spring preload and safety value), the first spring 27 is significantly compressed to provide cushioning, and at the same time, the data of the first sensor 24 exceeding the limit can trigger an alarm or shutdown. After the pressure is released, the first spring 27 pushes the first guide post 26 and the upper component to reset.

[0024] The X-direction pressure detection module is located on the upper side of the third fixed plate 23. The module includes a fourth fixed plate 31, a fifth fixed plate 32, and a sixth fixed plate 33 arranged parallel to each other along the X-direction.

[0025] Furthermore, a second spring 37 is sleeved on the outside of the second guide post, located between the fifth fixed plate 32 and the sixth fixed plate 33. The two second springs 37 are compressed (or stretched, depending on the direction of the lateral force), providing lateral elastic compensation and cushioning. If the pressure is too high, exceeding the data limit of the second sensor 34 can also trigger feedback. After the external force disappears, the second springs 37 help the mechanism reset.

[0026] Preferably, the front and rear ends of the fourth fixing plate 31 are respectively provided with third linear bearings 35, and the left side of the second guide post slides through the third linear bearing 35 and is fixed with a fixing ring.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
