Description

Technical Field

[0001] The utility model belongs to the technical field of display panel detection, and particularly relates to a double-head independent correction automatic plugging system. Background Art

[0002] In the field of in-vehicle liquid crystal display panel detection, most products need to be lit before detection. The common method is to connect electrical signals to the products through automatic crimping or automatic plugging to achieve lighting. The number of sockets may be single-headed or multi-headed. The current technical solutions usually use a fixture with an intermediate docking head on the carrier. The double ports on the female head side are of custom-designed dimensions, which are consistent with the plugging dimensions to be automatically docked at the bottom. However, due to possible incoming material deviations in the positions of the two interfaces on the fixture and the product, it is necessary to use the fixture for transfer, and the interfaces on the fixture and the product need to be manually plugged. This method makes it impossible for the equipment to achieve a fully automatic process, thus affecting the production capacity of the equipment and the high qualification rate of the products. Summary of the Utility Model

[0003] In order to solve all or part of the above prior art problems, the utility model provides a double-head independent correction automatic plugging system to overcome the problem of manual intervention and auxiliary plugging due to incoming material deviations of products.

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] A double-head independent correction automatic plugging system includes: a loading module for grasping, moving a product to be tested and carrying the product to be tested, and the product to be tested has a female head for plugging; a plugging module including a lifting mechanism, a plugging mechanism and a clamping mechanism arranged at the upper end thereof, and a male head matching the female head is installed on the plugging mechanism; the lifting mechanism is used to drive the plugging mechanism and the clamping mechanism to lift synchronously, so that the male head is plugged and connected with the female head; the clamping mechanism is used to fix or release the plugging mechanism; a visual control module for photographing the position of the female head of the product to be tested and generating a driving instruction according to the female head position information to drive the loading module to grasp and move the product to be tested.

[0006] By integrating the loading module, the plugging module and the visual control module, the system overcomes the problem of manual intervention and auxiliary plugging due to incoming material deviations of products. Through the precise positioning of the visual control module and the automatic operation of the plugging module, full-automatic plugging is realized, and the production efficiency and the product qualification rate are improved.

[0007] There are 2 female heads arranged on the product to be tested, and 2 plugging modules are provided. The system design not only supports single-head operation, but also can handle the plugging tasks of two female heads simultaneously.

[0008] The plug-in mechanism comprises a connecting shaft and an elastic member for mounting the male head, and two ends of the elastic member are respectively fixedly connected to the lower part of the connecting shaft and the upper end surface of the lifting mechanism.

[0009] When the clamping mechanism clamps the connecting shaft, the elastic member is in a compressed state; when the male connector and the female connector are plugged in, the clamping mechanism releases the connecting shaft, and the elastic member is in an upwardly stretched and / or offset state. The elastic member provides a force opposite to gravity, so that the vertical force of the entire plug-in mechanism reaches a balanced state. This gravity compensation mechanism can prevent unnecessary displacement or deformation of components due to gravity.

[0010] The connecting shaft is provided with a limiting groove, and the side wall of the limiting groove is provided with a relative cut surface. The limiting groove and the cut surface on the side wall can form reliable multi-point contact with the clamp during clamping, which can effectively prevent the connecting shaft from tilting or deflecting during clamping.

[0011] A clamping block is installed inside the clamping jaw of the clamping mechanism. The shape of the inner side surface of the clamping block is the same as the shape of the limiting groove. When the clamping jaw releases the connecting shaft, the connecting shaft is offset by 1-2 mm within the clamping range of the clamping jaw. This design can ensure that the connecting shaft can be accurately positioned at a predetermined position during the clamping process. When the clamping jaw releases the connecting shaft, since the limiting groove and the inner side surface of the clamping block are precisely matched, even if an offset occurs, it can be controlled within the range of 1-2 mm, thereby ensuring that the connecting shaft will not leave the clamping range and always remain in a controllable position area.

[0012] The loading module includes a loading gripper and a carrier, and the loading gripper includes a moving arm and a plurality of vacuum suction cups for grabbing and moving the product to be tested.

[0013] The platform is provided with a jig, and the shape and size of the profiling cavity on the jig are consistent with the product to be tested, and is used to accurately fix and place the product to be tested. Through the coordinated work of the feeding gripper and the platform, and the characteristics that the profiling cavity on the jig is consistent with the shape and size of the product to be tested, the operation accuracy, clamping stability and production efficiency are greatly improved, and human errors are reduced.

[0014] The visual control module includes a visual unit and a control unit. The visual unit is used to capture the position of the female head of the product to be tested and send it to the control unit. The control unit is used to receive the position information of the female head of the product to be tested, generate a driving instruction according to the female head position information, and drive the loading gripper to grab and move the product to be tested. After adopting the visual control module, the visual unit and the control unit work together to automatically complete the positioning and grabbing operations, eliminating the errors caused by human factors, thereby improving the stability and reliability of the entire system.

[0015] The uses of the double-headed independent correction automatic plugging system disclosed by the present utility model include: being applicable to the field of integrated processes of in-vehicle liquid crystal panel display panels and the plugging and unplugging application scenarios of double connectors.

[0016] The present invention has at least the following beneficial effects:

[0017] 1) Through the precise positioning of the visual control module and the automated operation of the plugging module, the accuracy and stability of the plugging process are effectively improved. It no longer relies on manual intervention, greatly reducing the errors introduced by human operation, ensuring that each plugging can be completed at the predetermined position and angle, thereby improving the quality and consistency of the product.

[0018] 2) Combining the collaborative work of the feeding module and the plugging module, this system can simultaneously handle the plugging tasks of two female connectors, significantly improving the production efficiency. The automated operation process ensures that more plugging tasks can be completed in a shorter time, strongly supporting the requirements of efficient manufacturing production.

[0019] 3) The elastic member and the limiting groove in the design of the plugging mechanism effectively achieve the compensation and control of gravity. This design ensures the stability of the connecting shaft during the plugging process, preventing unnecessary displacement or deformation caused by the influence of gravity, and further improving the reliability and service life of the system.

[0028] Next, the technical solutions in the specific embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] In the embodiments of the present utility model, with reference to Figures 1-6 As shown, a double-headed independent correction automatic plugging system includes a feeding module, a plugging module 3, and a vision control module, aiming to efficiently process the plugging requirements of the product to be tested 1. In this embodiment, there are 2 female heads on the product to be tested, and 2 plugging modules 3 are provided.

[0030] The feeding module is used to grasp, move, and carry the product to be tested 1, which has female head interfaces dedicated for plugging. Through precise grasping and safe movement, it provides the necessary material support for the subsequent plugging process. The feeding module includes a feeding gripper and a carrier 2. The feeding gripper adopts a moving arm structure and multiple vacuum suction cups to ensure the stable grasping and safe movement of the product to be tested 1. The moving arm is a multi-degree-of-freedom robotic arm that can flexibly adjust its posture and position to adapt to products to be tested 1 with different positions and shapes. The vacuum suction cups provide sufficient adsorption force to ensure that the product does not slide or shift during movement, thus ensuring the safety and stability of the operation. Special fixtures are provided on the carrier 2, and the profiling cavities of these fixtures are completely matched with the shape and size of the product to be tested 1. The design of the profiling cavity is aimed at ensuring that the product to be tested 1 can be accurately fixed and placed, so as to be accurately positioned to the position required for the subsequent plugging operation.

[0031] The plug-in module 3 includes a lifting mechanism 31, a plug-in mechanism 32, and a clamping mechanism 33. The plug-in mechanism 32 and the clamping mechanism 33 are arranged at the upper end of the lifting mechanism 31, and the male head 321 that is matched and plugged with the female head is installed on the plug-in mechanism 32. The lifting mechanism 31 is used to drive the plug-in mechanism 32 and the clamping mechanism 33 to lift synchronously, so as to ensure that the male head 321 can be accurately docked to the position of the female head during the plugging process. The clamping mechanism 33 is used to fix or release the plug-in mechanism 32 to ensure the stability and safety of the plugging operation. The plug-in mechanism 32 includes a connecting shaft 322 and an elastic member 323. The two ends of the elastic member 323 are respectively fixedly connected to the lower part of the connecting shaft 322 and the upper end surface of the lifting mechanism 31. These components are designed to install the male head 321 and adjust the pressure and position during plugging. When the clamping mechanism 33 clamps the connecting shaft 322, the elastic member 323 is in a compressed state; when the male head 321 is plugged with the female head, the clamping mechanism 33 releases the connecting shaft 322, and the elastic member 323 has an upward stretching and / or offset state. The connecting shaft 322 is provided with a limiting groove and corresponding cut surfaces on the side wall, and these designs are aimed at ensuring accurate positioning and stability during plugging. The clamping block 331 is installed inside the clamping jaw of the clamping mechanism 33, and the shape of its inner side surface matches the shape of the limiting groove on the connecting shaft 322. During the plugging process, after the clamping mechanism 33 releases the connecting shaft 322, the connecting shaft 322 may be offset by about 1-2 mm under the action of the clamping block 331. This tiny offset amount ensures the flexibility and accuracy during the plugging process while maintaining a reliable connection between the male and female heads.

[0032] The vision control module is used to photograph the position of the female head of the product 1 to be tested, and generate a driving instruction according to the position information of the female head, so as to drive the feeding module to accurately grasp and move the product 1 to be tested. The vision control module includes a vision unit 4 and a control unit. The vision unit 4 uses a high-performance CCD camera to photograph the position of the female head of the product 1 to be tested, and this image information will be sent to the control unit in a timely manner for subsequent data processing and analysis. The control unit is used to receive the position information of the female head of the product 1 to be tested from the vision unit 4 and process this information. Based on the processing result, the control unit generates a corresponding driving instruction to guide the gripper of the feeding module to perform precise grasping and moving operations. The control unit usually integrates advanced algorithms and processors, and can analyze image data in real time and quickly generate precise driving instructions to ensure the efficiency and accuracy of the entire operation process.

[0033] A double-head independent correction automatic plugging method provided in this embodiment is implemented by using the double-head independent correction automatic plugging system provided above, and includes the following steps:

[0034] S1. The feeding module grasps and moves the product 1 to be tested and suspends it above the stage 2. The vision control module is activated to take a photo of the product 1 to be tested and capture the position of the first female head. Based on the image processing results, the vision control module generates precise driving instructions and transmits them to the feeding module. The feeding module moves the product 1 to be tested according to the instructions so that it is directly above the first male head.

[0035] S2. After the product 1 to be tested is directly above the first male head, the feeding module remains stable. The lifting mechanism 31 is activated and gradually rises to insert the first male head into the first female head, completing the insertion of the first set of male and female heads. After the insertion is completed, the clamping mechanism 33 releases the inserted male head.

[0036] S3. The vision control module is activated again to take a second photo of the product 1 to be tested to determine the position of the second female head. Based on the captured position information, the vision control module generates new driving instructions and sends them to the feeding module. The feeding module executes the instructions and moves the product 1 to be tested so that it faces the second male head.

[0037] S4. After the product 1 to be tested is directly above the second male head, the feeding module remains stable. The lifting mechanism 31 is activated and gradually rises to insert the second male head into the second female head, completing the insertion of the second set of male and female heads. After the insertion is completed, the clamping mechanism 33 releases the inserted male head. The feeding module moves the product 1 to be tested with the insertion completed into the profiling cavity of the fixture on the stage 2, preparing for testing.

[0038] S5. The functional test of the product 1 to be tested is completed in the profiling cavity. After the test is completed, the clamping mechanism 33 clamps the two male heads 321 respectively. The lifting mechanism 31 is activated and moves downward to separate the inserted male heads 321 and female heads of the first and second sets. After the separation is completed, the feeding module removes the tested product and returns to the initial position, preparing for the next cycle.

[0039] In step S2, through the automatic release mechanism after the insertion operation, freedom is provided for the positioning of another interface. The system can not only achieve the precise insertion of the first interface, but also provide the required freedom for the positioning of the next interface through the release and loosening mechanism. This method can be extended to the application of multiple interfaces and is also applicable to other requirements for automatic correction. For example, in the assembly process of multi-interface devices, each interface can be automatically released after insertion, providing adjustment space for the accurate positioning of subsequent interfaces. This strategy improves the flexibility and precision of the system, helps to achieve unmanned operation in equipment production, improves production efficiency and reduces human intervention. This is a very effective automated solution for production lines that require high precision and high efficiency, such as the manufacture of in-vehicle liquid crystal display panels and the assembly of other electronic devices.

[0040] In step S5, after the male head 321 and the female head are separated, the plugging module 3 is restored to the initial state by the lifting device at the bottom.

[0041] The double-headed independent correction automatic plugging method provided by the present utility model realizes efficient and accurate automatic plugging operations through advanced vision control technology and precise mechanical operations, greatly improving the automation level of the production line and the product quality, and is particularly suitable for the comprehensive manufacturing process of in-vehicle liquid crystal display panels and other plugging and unplugging application scenarios of double connectors.

[0042] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the scope of protection of the claims of the present utility model.
