Description

Technical Field

[0001] The present invention relates to the field of ceramic shells, and in particular to a new energy ceramic shell leak detection multi-cavity sub-detection system and method. Background Art

[0002] Ceramic shell leak detection methods include air tightness detection, water pressure detection, fluorescence detection, ultrasonic detection and resistance method. Each method is suitable for different detection needs. It determines whether there are micropores or cracks in the shell through pressurization, gas or liquid penetration, ultrasonic signal response, resistance change, etc., to ensure its sealing and reliability.

[0003] At present, the leak detection method of new energy ceramic shells in the industry mainly relies on manual helium inspection. Although this method is suitable for small batch inspection, it has the following problems: First, manual operation leads to low inspection efficiency, and due to frequent manual contact, it may cause damage or contamination to the product surface, thus affecting the consistency and reliability of the product; second, manual inspection cannot achieve real-time automatic sorting, that is, it cannot automatically distinguish between defective products and qualified products during the inspection process. Therefore, after the entire batch is inspected, it is still necessary to further manually screen defective products, which increases additional workload and labor costs.

[0004] Therefore, the present invention provides a new energy ceramic shell leak detection multi-cavity sub-detection system and method to solve the problems raised in the above background technology. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a new energy ceramic shell leak detection multi-cavity inspection system, including a symmetrically arranged large cavity A and a large cavity B, the two have the same structure, each large cavity includes six small cavities, which are arranged in 2*3 rows, and a sorting platform is installed above the small cavity. A test position is opened at the position where each small cavity contacts the sorting platform, and the six small cavities of the large cavity A correspond to the test positions A1-A6 respectively, and the six small cavities of the large cavity B correspond to the test positions B1-B6 respectively.

[0006] Preferably, a plurality of inspection valves are installed at the bottom of the sorting platform, and an air intake valve is arranged below the inspection valve.

[0007] Preferably, a sub-check valve is arranged on one side of the check valve.

[0008] Preferably, the large cavity A and the large cavity B are both controlled by a robotic arm.

[0009] Preferably, a movable conversion platform is installed above the sorting platform, and a capping cylinder is provided above the conversion platform.

[0010] Preferably, a first helium sensing unit is arranged in the small cavity, and a second helium sensing unit is arranged on the inner walls of the large cavities A and B.

[0011] The present invention also provides a new energy ceramic shell leak detection multi-cavity separation method, comprising the following steps:

[0012] Step S1, helium leak detection: perform helium detection on the large cavity A as a whole, including small cavities A1-A6. When the helium leakage rate of the large cavity A is detected to exceed the standard value, the system determines that the large cavity A is NG and automatically enters the sub-inspection step;

[0013] Step S2, sorting process: when the large cavity A enters the sorting inspection, A1-A6 automatically separate the cavities for leak detection until NG products in each small cavity are detected;

[0014] Step S3, separation and marking: after detecting a specific NG small cavity, the small cavity is separated onto a sorting platform, and the NG product is automatically removed from the production line or marked as required;

[0015] Step S4, alternating work: when large cavity A is in the process of sorting, large cavity B performs alternating work. Large cavity B includes six small cavity test positions B1-B6, and the detection principle is the same as A.

[0016] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0017] 1. The symmetrical arrangement of large cavity A and large cavity B and their respective small cavities can achieve efficient helium leak detection. Each small cavity is independently set with a test position, making the detection process more comprehensive and accurate, and can quickly identify leaking parts, improving the overall detection efficiency.

[0018] 2. The system can automatically identify and separate unqualified (NG) small cavities, reducing the need for manual intervention and the workload of operators; by installing a helium sensor unit, the leak point can be detected more accurately, improving the sensitivity and reliability of leak detection.

[0019] 3. Through the alternating working mechanism of large cavity A and large cavity B, the two large cavities can perform leak detection and sorting at the same time, maximizing the utilization rate of the equipment and avoiding production stagnation. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0025] Embodiment 1

[0026] See also Figures 1-2 In this embodiment, a new energy ceramic shell leak detection multi-cavity sorting system is provided, including a symmetrically arranged large cavity A1 and a large cavity B2, the two having the same structure, each large cavity including six small cavities 3, arranged in a 2*3 positive row, a sorting platform 4 is installed above the small cavity 3, and a test position 11 is opened at the position where each small cavity contacts the sorting platform 4, the six small cavities of the large cavity A correspond to the test positions A1-A6 respectively, and the six small cavities of the large cavity B correspond to the test positions B1-B6 respectively. A first helium sensing unit 9 is arranged in the small cavity 3, and a second helium sensing unit 10 is arranged on the inner wall of the large cavity A1 and the large cavity B2. When working, nitrogen is introduced into the large cavity A1, and the second nitrogen sensing unit detects the nitrogen content. When the leak detection rate of the large cavity A1 is greater than the standard value, the test position will be judged as NG and automatically enter the sorting inspection. Nitrogen is introduced into the small cavity 3 alone, and the nitrogen content in the small cavity 3 is detected by the first nitrogen sensing unit 9, so as to judge the NG products in the small cavity 3. The design of alternating automatic loading and unloading of the large cavity A1 and the large cavity B2 and alternating automatic leak detection and multi-cavity sorting inspection saves the time of manual loading, and the reliable manipulator precision ensures the accurate positioning and loading and unloading of the cavity, so that the large cavity A1 and the large cavity B2 can be automatically loaded and unloaded alternately.

[0027] The large cavity A1 and the large cavity B2 are both controlled by a robotic arm. During operation, the loading and unloading of products in the large cavity A1 and the large cavity B2 are both autonomously controlled by the robotic arm.

[0028] A sorting platform 4 is installed at the bottom of the large cavity A1 and the large cavity B2, and a plurality of inspection valves 5 are installed at the bottom of the sorting platform 4. An air inlet valve 6 is arranged below the inspection valve 5, and a sub-inspection valve 7 is arranged on one side of the inspection valve 5. During operation, nitrogen is introduced through the air inlet valve 6, and the inspection valve 5 is opened, so that nitrogen enters the large cavity A1 for testing. When the test is abnormal, the sub-inspection valve 7 is opened, so that the products in the small cavity 3 in the large cavity A1 are tested one by one, so as to find out NG products.

[0029] A movable conversion platform 11 is installed above the sorting platform 4, and a capping cylinder 8 is provided above the conversion platform 11. NG products on the sorting platform 4 can be marked, collected or removed. This function ensures that NG products can be quickly and effectively removed from the production line, avoiding the impact on subsequent production.

[0030] During specific operation, nitrogen is introduced into the large cavity A1, and the second nitrogen sensing unit 10 detects the nitrogen content. When the leak detection rate of the large cavity A1 is greater than the standard value, the test position will be judged as NG and automatically enter the sub-inspection. Nitrogen is introduced into the small cavity 3 alone, and the nitrogen content in the small cavity 3 is detected by the first nitrogen sensing unit 9, so as to judge the NG products in the small cavity. The design of alternating automatic loading and unloading of the large cavity A1 and the large cavity B2 and alternating automatic leak detection and multi-cavity sub-inspection saves the time of manual loading, and the reliable manipulator precision ensures the accurate positioning and loading and unloading of the cavity, so that the large cavity A and the large cavity B can be automatically loaded and unloaded alternately.

[0031] Embodiment 2

[0032] See also Figure 3 A multi-cavity inspection method for leak detection of a new energy ceramic shell is implemented by the inspection device of the first embodiment, comprising the following steps:

[0033] Step S1, helium leak detection: Perform helium detection on the large cavity A as a whole, including small cavities A1-A6. When the helium leakage rate of the large cavity A is detected to exceed the standard value, the system determines that the large cavity A is an NG product and automatically enters the sub-inspection step; by performing helium detection on the large cavity A as a whole, potential leakage problems are effectively identified to ensure the sealing of the components. The system automatically determines unqualified (NG) products according to the set standards, reduces manual intervention, improves detection speed and accuracy, detects problems early, and reduces the risk of losses in subsequent production links.

[0034] Step S2, sorting and processing: When the large cavity A enters the sorting inspection, A1-A6 automatically conducts leak detection in each cavity until the NG products in each small cavity are detected; at this stage, each small cavity (A1-A6) is leak-checked one by one, and the specific NG small cavity can be accurately located, which is convenient for targeted processing and optimizes resource utilization, ensuring that only parts that need to be repaired or replaced are processed, thereby improving production efficiency and response speed.

[0035] Step S3, separation and marking: After detecting a specific NG small cavity, separate the small cavity onto the sorting platform, and automatically remove the NG product from the production line or mark it as needed; by quickly removing the NG small cavity from the production line, this step can effectively prevent unqualified products from continuing to flow into the next process, reducing the rework rate and customer complaint risk. At the same time, marking NG products facilitates subsequent analysis and problem tracking, helps to continuously improve the production process, and ensures smooth operation of the production line.

[0036] Step S4, alternating work: when large cavity A is in the process of sorting, large cavity B is in alternating work, and large cavity B contains six small cavity test positions B1-B6, and the detection principle is the same as A. It ensures that the production line does not stagnate, thereby improving the overall production capacity, maximizing the efficiency of equipment use, reducing the risk of shutdown caused by single point failure, and enabling enterprises to have stronger flexibility and competitiveness in a rapidly changing market environment.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
