[0002] Currently, in the production process of lithium-ion batteries and other batteries, after secondary liquid injection, the product needs to be sealed with sealing nails to seal the liquid injection port, so as to ensure the airtightness of the battery product. At the same time, a secondary helium test is also required to check the airtightness of the weld.

[0003] In the existing welding inspection process, battery products need to be transferred to the turntable or circulation line of the machine by a robotic arm.

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0059] like Figures 1-10 As shown, this application embodiment provides a conveying mechanism, including a first conveying line 100, a second conveying line 200, and a helium detection tray 110.

[0060] The first conveyor line 100 and the second conveyor line 200 are used to transport products, so that corresponding processes (such as welding, inspection, and sorting) can be completed simultaneously while the products are being transported on the first conveyor line 100 and the second conveyor line 200. In operation, the inlet of the first conveyor line 100 is connected to the outlet of the preceding material flow line, allowing products to be directly transported from the preceding material flow line to the first conveyor line 100 for loading. Correspondingly, the outlet of the second conveyor line 200 is connected to the inlet of the following material flow line, allowing products to be transported a certain distance on the second conveyor line 200 before being directly transported to the lower material flow line for unloading.

[0061] It should be noted that the products involved in this solution are preferably battery cells. After the battery cell is filled with electrolyte, the filling hole needs to be sealed with a sealing pin. After sealing, a preliminary test is required to check the airtightness of the weld. This mainly involves the welding and testing process of the sealing pin of the battery cell. That is, the product is a battery cell to be processed before welding, and a battery cell to be processed after welding. The product is a battery cell to be tested before helium testing, and a battery cell to be tested after helium testing. Since this solution does not protect the product itself, it is referred to as the product in this document, which does not affect the completeness of the solution. Of course, the product can also be other similar products.

[0062] The helium detection tray 110 is used to carry products. By cooperating with the helium detection cover 150, it can form a sealed chamber to accommodate the products for helium detection within the sealed chamber. Furthermore, both ends of the helium detection tray 110 are respectively connected to the first conveyor line 100 and the second conveyor line 200. In use, the inlet of the helium detection tray 110 is connected to the outlet of the first conveyor line 100, allowing products to be directly conveyed from the first conveyor line 100 onto the helium detection tray 110 for helium detection. The outlet of the helium detection tray 110 is connected to the inlet of the second conveyor line 200, allowing products to be directly conveyed from the helium detection tray 110 onto the second conveyor line 200 for corresponding processes to be completed on the second conveyor line 200 (such as sorting products based on helium detection results).

[0063] It should be noted that during the specific docking process, the first conveyor line 100 can be positioned between the front logistics line and the second conveyor line 200, the second conveyor line 200 can be positioned between the first conveyor line 100 and the lower logistics line, and the helium inspection tray 110 can be positioned between the first conveyor line 100 and the second conveyor line 200 to achieve sequential product conveying. Furthermore, the conveying surfaces of the front logistics line, the first conveyor line 100, the helium inspection tray 110, the second conveyor line 200, and the rear logistics line can be on the same plane to ensure stable product connection. For example, the conveying methods of the front logistics line, the first conveyor line 100, the helium inspection tray 110, the second conveyor line 200, and the rear logistics line can all be set as belt conveyors, chains, or chain plates.

[0064] Of course, there are no restrictions on the form of connection between the first conveyor line and the front logistics line, or between the second conveyor line and the rear logistics line. The first conveyor line and the front logistics line, as well as the second conveyor line and the rear logistics line, can also form a complete line, and products can be transported in a continuous manner. Alternatively, products from the front logistics line can be moved to the first conveyor line by a robotic arm, or products from the second conveyor line can be moved to the rear logistics line.

[0065] The helium detection tray 110 includes a tray body 111 and a connecting conveyor assembly. The tray body 111 forms part of the helium detection mechanism 6 and can be matched with the helium detection cover 150 of the helium detection mechanism 6 so that the tray body 111 and the helium detection cover 150 form a sealed chamber. The helium detection test is completed by placing the product in the sealed chamber. In use, the product is placed on the upper surface of the tray body 111, and the product is sealed in the sealed chamber by covering the upper surface of the tray body 111 with the helium detection cover 150. Specifically, a sealing gasket can be provided between the tray body 111 and the helium detection cover 150.

[0066] Of course, in other solutions, such as Figure 10 As shown, the product is carried in a fixture, and the product is transported by conveying the fixture. When the fixture is on the tray body, the fixture can match the helium test cover 150 so that the fixture and the helium test cover 150 form a closed chamber. By placing the product in the closed chamber, the helium test is completed.

[0067] The connecting conveyor assembly is disposed on the pallet body 111. Specifically, the connecting conveyor assembly can be disposed on the upper surface of the pallet body 111 or on the side of the pallet body 111. Moreover, the connecting conveyor assembly can carry products through the pallet body 111, so that the upper surface of the pallet body 111 becomes part of the product conveying line, and products can be transported onto the pallet body 111 without the need for complex handling structures such as robotic arms.

[0068] During operation, the two ends of the first conveyor line 100 are connected to the front logistics line and the pallet body 111, respectively, so that the products to be processed are directly conveyed onto the first conveyor line 100. The two ends of the pallet body 111 are connected to the first conveyor line 100 and the second conveyor line 200, respectively, so that the products to be helium tested are directly conveyed onto the pallet body 111. The two ends of the second conveyor line 200 are connected to the pallet body 111 and the rear logistics line, respectively, so that the products that have completed helium testing are directly conveyed onto the second conveyor line 200 and the subsequent rear logistics line. While conveying the products, processing and testing of the products can also be completed, which can greatly improve work efficiency.

[0069] This setup connects the front logistics line, the first conveyor line 100, the helium inspection tray 110, the second conveyor line 200, and the rear logistics line into a single product conveyor line that can be directly connected and transported. This allows for the transport of products in an assembly line format. Simultaneously, corresponding processes (such as nailing, welding, inspection, helium inspection, re-inspection, and sorting) can be completed on the first conveyor line 100, the helium inspection tray 110, and the second conveyor line 200. This facilitates the integration of welding and helium inspection, avoids product transfer between welding and helium inspection, eliminates the need for complex transfer structures such as robotic arms, and allows product processing and inspection to be completed during transport. The simple structure improves work efficiency.

[0070] This conveying mechanism includes a sensing component, which is at least located on one side of the helium detection tray 110 and is used to sense the position of the product on the helium detection tray 110 (i.e., whether the product is completely on the helium detection tray 110; when the product is completely on the helium detection tray 110, the helium detection tray 110 cooperates with the helium detection cover 150 to allow the product to be located in a sealed chamber for helium detection). Specifically, the sensing component can be in the form of an infrared sensor, a distance sensor, or a CCD camera. The installation position of the sensing component can be located on one side or both sides of the helium detection tray 110. Here, the specific installation is based on the specific structure of the sensing component to facilitate accurate sensing and positioning of the product on the helium detection tray 110.

[0071] Furthermore, the first conveyor line 100, the second conveyor line 200, and the connecting conveyor assembly are all communicatively connected to the sensing component, so as to control the conveying of the first conveyor line 100, the second conveyor line 200, and the connecting conveyor assembly according to the sensing content of the sensing component. For example, when the product is conveyed from the first conveyor line 100 to the pallet body 111, the first conveyor line 100 and the connecting conveyor assembly work simultaneously. When the product is completely on the pallet body 111, at least the connecting conveyor assembly stops working to keep the product on the pallet body 111.

[0072] In this way, by setting up the sensing components, the position of the product can be located, thereby enabling the first conveyor line 100, the second conveyor line 200 and the connecting conveyor components to coordinate the conveying of the product, so as to ensure the accuracy of the product's position during conveying.

[0073] This conveying mechanism includes a limiting component disposed on the pallet body 111 on one side near the second conveyor line 200, which can restrict the product from being conveyed from the pallet body 111 to the second conveyor line 200. Through the limiting effect of the limiting component, the product can be held on the pallet body 111.

[0074] During operation, the pallet body 111 can accommodate multiple products or multiple fixtures (the fixtures are used to support the products and move them during transport), allowing for simultaneous helium testing of batches of products. Within the same batch, when the first product is transported onto the pallet body 111, its movement is stopped by the limiting components. The second and subsequent products continue to move until adjacent products contact each other, at which point the limiting components also stop the movement. Finally, when all products in the same batch are transported onto the pallet body 111, the connecting conveyor stops transporting the products, and the limiting components release their restraints, allowing for simultaneous helium testing of the same batch of products.

[0075] In this way, by cooperating with the limiting component and the connecting conveyor component, the pallet body 111 can simultaneously carry multiple products of the same batch, preventing products from flowing out of the pallet body 111, so as to complete the simultaneous helium inspection of multiple products of the same batch, which is beneficial to improving the efficiency of helium inspection.

[0076] Specifically, the limiting component includes a baffle and a cylinder for moving the baffle. Under the action of the cylinder, the baffle can block the products on the pallet body 111, or it can remove the baffle from blocking the products on the pallet body 111. The structure is simple, stable and reliable.

[0077] In this design, the first conveyor line 100 and the second conveyor line 200 are on the same straight line, and the helium inspection tray 110 is located between the first conveyor line 100 and the second conveyor line 200, so that the first conveyor line 100, the helium inspection tray 110, and the second conveyor line 200 transport products along the same straight line. This allows for the installation of other mechanisms on the conveying mechanism (specifically, one or more mechanisms for performing operations such as nailing, welding, inspection, helium inspection, re-inspection, and sorting on the products), where multiple other mechanisms can be distributed on the same straight line or on both sides of the same straight line. This saves space, facilitates debugging and maintenance by personnel, and ultimately helps ensure the stability and reliability of the workflow.

[0078] This application provides a sealing nail welding inspection system, including a conveying mechanism, which is the conveying mechanism in the above embodiment.

[0079] This setup connects the front logistics line, the first conveyor line 100, the helium inspection tray 110, the second conveyor line 200, and the rear logistics line into a single product conveyor line that can be directly connected and transported. This allows for the transport of products in an assembly line format. Simultaneously, corresponding processes (such as nailing, welding, inspection, helium inspection, re-inspection, and sorting) can be completed on the first conveyor line 100, the helium inspection tray 110, and the second conveyor line 200. This facilitates the integration of welding and helium inspection, avoids product transfer between welding and helium inspection, eliminates the need for complex transfer structures such as robotic arms, and allows product processing and inspection to be completed during transport. The simple structure improves work efficiency.

[0080] like Figure 3 As shown, this sealing nail welding inspection system includes a nail mounting mechanism and a welding mechanism 4.

[0081] The nailing mechanism and the welding mechanism are installed on the first conveyor line. Specifically, "installed on the first conveyor line" means that the nailing mechanism and the welding mechanism can be installed above the first conveyor line or on one side of the first conveyor line.

[0082] The nailing mechanism is used to nail the products on the first conveyor line 100 online, so as to transfer the sealing nails into the liquid injection hole of the product. Here, the nailing mechanism is set at the nailing station. During the process of conveying the products, the first conveyor line 100 can convey the products to the nailing station so that the nailing mechanism at the nailing station can nail the products.

[0083] Specifically, the nailing mechanism includes a vibratory feeder assembly 2 and an assembly assembly 3. The vibratory feeder assembly 2 is used to transport the sealing nails to the assembly station by means of vibration feeding. The assembly assembly 3 is used to assemble the sealing nails at the assembly station onto the product at the nailing station. The assembly assembly 3 can be set as a robotic arm or other gripper.

[0084] The welding mechanism 4 is used to perform online welding operations on the products on the first conveyor line 100, so that the sealing nail located in the liquid injection hole of the product is welded and fixed to the product, thereby achieving internal welding sealing of the product. Here, the welding mechanism 4 is set at the welding station. During the process of conveying products, the first conveyor line 100 can transport the products to the welding station so that the welding mechanism 4 at the welding station can perform welding operations on the products.

[0085] It should be noted that the term "online" in this article refers to a streamlined operation that takes place directly during the transportation process without the need for handling or transfer.

[0086] During product processing, the first conveyor line 100 connects with the preceding logistics line and the second conveyor line 200, allowing the product to be directly input and processed on the first conveyor line 100. Furthermore, driven by the first conveyor line 100, the product can move along it to the nailing station and the welding station. The nailing mechanism performs nailing operations on the product at the nailing station, and the welding mechanism 4 performs welding operations on the product at the welding station, thus completing the sealing nail welding process. The entire processing is completed on the first conveyor line 100, reducing product transfer operations, simplifying the processing structure, and improving work efficiency. Moreover, when the product is supported by the fixture 101, the fixture 101 is always transported on the first conveyor line 100, eliminating the need for repeated loading and unloading of the product on the fixture 101 or for changing the fixture 101, which facilitates precise product positioning.

[0087] With this setup, during the sealing nail welding process, products can flow in and out without the need for complex handling structures such as robotic arms. The use of an assembly line for connecting and conveying can improve product processing efficiency. Moreover, the entire processing process is completed on the first conveyor line 100, which can reduce product transfer operations, simplify the processing structure, and facilitate precise product positioning.

[0088] To improve the processing quality of the product, the sealing nail welding inspection system also includes a cleaning mechanism 1 and / or an inspection mechanism 5.

[0089] The cleaning mechanism 1 is used to clean the liquid injection port of the product on the first conveyor line 100 to prevent impurities in the liquid injection port from interfering with the position of the sealing nail when the sealing nail is being fed. Specifically, the cleaning mechanism 1 is set at the cleaning station. During the process of conveying the product, the first conveyor line 100 can transport the product to the cleaning station so that the cleaning mechanism 1 at the cleaning station can perform the cleaning operation on the product.

[0090] The inspection mechanism 5 is used to inspect the products on the first conveyor line 100 to check the welding quality of the products, facilitating subsequent scrap screening. Here, the inspection mechanism 5 is located at the inspection station. During the product transport process, the first conveyor line 100 can transport the products to the inspection station, allowing the inspection mechanism 5 at the station to perform inspection operations. Specifically, the inspection mechanism 5 is equipped with a CCD camera, which inspects the welding quality of the products through image processing, enabling a preliminary screening of the products and reducing the workload of subsequent helium inspection.

[0091] It should be noted that the cleaning mechanism 1, the nailing mechanism, the welding mechanism 4, and the inspection mechanism 5 mentioned above can all be structures in the prior art. The focus here is on the structural coordination form that completes the cleaning operation, loading operation, welding operation, and inspection operation during the product conveying process of the first conveyor line 100. Moreover, the cleaning station, loading station, welding station, and inspection station mentioned above can be arranged sequentially along the conveying direction of the first conveyor line 100 to facilitate the sequential completion of the cleaning operation, loading operation, welding operation, and inspection operation. Specifically, the cleaning station, loading station, welding station, and inspection station can be a corresponding spatial position on the first conveyor line 100, so that the cleaning mechanism 1, the nailing mechanism, the welding mechanism 4, and the inspection mechanism 5 can be respectively set at the corresponding station and perform the cleaning operation, loading operation, welding operation, and inspection operation on the product at the corresponding station.

[0092] In some embodiments, a guide structure is provided on the first conveyor line 100. The guide structure can guide the displacement of the product so that the product always moves along the conveying direction of the first conveyor line 100 during the conveying process. This avoids the product deviating from the conveying direction of the first conveyor line 100 due to other interferences (such as the sliding caused by its own imbalance on the conveying surface, or the processing force applied to the product by other mechanisms during processing), thereby affecting the positioning of the product and the processing accuracy.

[0093] like Figure 1 As shown, the product is supported on the fixture, and the guiding structure includes a guide plate 102. The fixture 101 is a device for accommodating the product. One fixture 101 can accommodate multiple products at the same time. Under the support of the fixture 101, multiple products can be transported and processed in batches, which is beneficial to improving processing efficiency. Multiple guide plates 102 are provided (preferably two). Multiple guide plates 102 are respectively arranged on both sides of the first conveyor line 100, and a guiding path is formed between the guide plates 102. The guiding path is formed above the conveying surface of the first conveyor line 100, and the width of the guiding path matches the width of the fixture 101 so that the guiding path can be just enough for the fixture 101 to pass through. The fixture 101 is guided by the guide plates 102 so that the fixture 101 is displaced along the conveying direction of the first conveyor line 100. Since the product is located on the fixture 101, guiding the fixture 101 can achieve the product's guidance. Thus, guiding the product by guiding the fixture 101 can be achieved by the guide plate 102 contacting the fixture 101 to guide it, avoiding contact and collision between the product and the guide plate 102, which is beneficial for product protection.

[0094] Specifically, guide wheels are provided at the four corners of the fixture 101. Through the cooperation of the guide wheels and the guide plate 102, rolling friction can be generated between the fixture 101 and the guide plate 102 to improve the stability of the fixture 101 and the product conveying.

[0095] In other embodiments, the guiding structure includes a guiding component 103, which is elongated and extends in the same direction as the conveying direction of the first conveyor line 100, so that the extension direction of the guiding component 103 is the guiding direction for the product. Multiple guiding components 103 are provided (specifically, four or five, depending on the relative width of the first conveyor line 100 and the product). These multiple guiding components 103 are arranged at intervals along the perpendicular direction of the conveying direction of the first conveyor line 100, forming a guiding path for the product to pass through between adjacent guiding components 103. This guiding path is formed above the conveying surface of the first conveyor line 100, and the width of the guiding path matches the width of the product, so that the guiding path can just accommodate the product. Thus, the product is guided by multiple guiding components 103, causing the product to move along the conveying direction of the first conveyor line 100. Since there are multiple guide components 103, multiple guide paths can also be formed. For example, if there are five guide components 103, four guide paths can be formed. By guiding and conveying multiple products on multiple guide paths at the same time, the guidance of multiple products in an array can be realized, which is conducive to the accurate positioning of each product and improves the stability of product conveying and guidance.

[0096] like Figure 2 As shown, the guide assembly 103 includes a roller frame and multiple rollers. The extending direction of the roller frame is consistent with the conveying direction of the first conveyor line 100. The multiple rollers are rotatably mounted on the roller frame and are spaced apart along the extending direction of the roller frame. This creates roller surfaces on the sides of adjacent roller frames. When the guide assembly 103 guides the product, the product can roll along the roller surfaces, thereby improving the stability of product conveying through the rolling friction generated between the product and the rollers.

[0097] Specifically, multiple rollers are provided on both sides of the roller frame to form a roller surface, so as to avoid interference between two adjacent guide paths and thus improve the reliability of the guide assembly 103.

[0098] Of course, in other solutions, the guide component 103 can also be set in the form of a sliding plate, and the guide component 103 can achieve its guiding function by the sliding friction between the product and the sliding plate.

[0099] In some embodiments, a limiting mechanism is provided on the first conveyor line 100. The limiting mechanism can keep the product at the nailing station where the nailing mechanism is located or the welding station where the welding mechanism 4 is located, so that when the nailing mechanism and the welding mechanism 4 perform processing operations on the product (nailing operation and welding operation, respectively), the product position is kept at the corresponding position on the first conveyor line 100. By performing processing operations on the product with a fixed position, the accuracy and stability of processing can be improved, which is conducive to ensuring the precise positioning of the product to be processed.

[0100] Specifically, two limiting mechanisms can be provided to keep the product at the nailing station and the welding station respectively. Of course, in combination with the cleaning mechanism 1 and the detection structure, four limiting mechanisms can be provided to keep the product at the cleaning station, the nailing station, the welding station and the detection station respectively.

[0101] The limiting mechanism includes a blocking component and a lifting component. The blocking component is used to prevent the product from moving along the conveying direction of the first conveyor line 100, so that the product's position is fixed at the corresponding work station. Specifically, under the action of the first drive (such as a cylinder or hydraulic cylinder), the blocking component can move relative to the first conveyor line 100, so that the blocking component can both block the product and release the product, thereby controlling the start and stop of the product.

[0102] The lifting component is used to lift the product, thereby removing it from the conveying action of the first conveyor line 100. Simultaneously, the lifting component holds the product at a corresponding work position, thus preventing the force between the first conveyor line 100 and the product from affecting the product's processing quality. Specifically, under the action of a second drive (such as a pneumatic or hydraulic cylinder), the lifting component can be displaced relative to the first conveyor line 100, causing the product to rise or fall relative to the first conveyor line 100. This allows the product to either detach from the first conveyor line 100 or remain on it for conveying, thereby controlling whether the product contacts the first conveyor line 100.

[0103] Of course, in other solutions, the limiting mechanism can also be set as a clamp, which can clamp and lift the product at the corresponding workstation to achieve the limiting and holding function.

[0104] In this scheme, the first conveyor line 100 is set as a double-speed chain structure or a conveyor belt structure to have high stability, so as to facilitate precise control and positioning of the product and ensure processing quality.

[0105] Here, in conjunction with the above-mentioned limiting mechanism, in order to ensure that the lifting component can drive the product to lift, the first conveyor line 100 has two double-speed chain structures or conveyor belt structures, which are parallel and spaced apart to form a conveying area on both, so that the two can support and convey the two ends of the product (fixture 101) respectively. The lifting component is set in the area between the two, so that the lifting component can protrude and be recessed in the conveying surface of the first conveyor line 100.

[0106] Moreover, the first conveyor line 100 extends in a straight line, which makes the installation structure of the double-speed chain structure or the conveyor belt structure simple, stable and reliable, and helps to save costs.

[0107] like Figure 4 As shown, the connecting conveyor assembly includes a connecting conveyor 112 and a connecting drive 113. The connecting conveyor 112 is used to carry and convey the product. The connecting conveyor 112 extends from one end of the pallet body 111 to the other end to facilitate connection with the preceding and following product conveyor lines and ensure the stability of the conveying. The connecting drive 113 is connected to the connecting conveyor 112 and can drive the connecting conveyor 112 to form a conveying action, so that the connecting conveyor 112 moves the product from one end of the pallet body 111 to the other end, thereby allowing the product to pass through the pallet body 111.

[0108] Specifically, the connecting drive unit 113 has a fixed end and a drive end (the connecting drive unit 113 can be configured as a motor, with the fixed end and drive end being the motor housing and motor drive shaft, respectively). The fixed end is fixed to the pallet body 111, and the drive end can rotate relative to the fixed end. The connecting conveyor line can be configured as a double-speed chain or a conveyor belt, having a double-speed chain or conveyor belt that carries the product and a drive wheel that drives the double-speed chain or conveyor belt to rotate and convey the product. The drive wheel is connected to the drive end, thereby realizing the transmission connection between the connecting drive unit 113 and the connecting conveyor unit 112. Moreover, multiple double-speed chains and conveyor belts can be arranged in parallel (preferably two, but three or four are also possible), and evenly distributed on the pallet body 111 to ensure the stability of product conveying.

[0109] With this configuration, the product is carried and transported by the connecting conveyor 112 without relative displacement with the product, which has good transport stability and can ensure the accuracy of the relative position of the product during transport.

[0110] Of course, in some other solutions, the connecting conveyor assembly can also be configured in other forms. For example, the connecting conveyor assembly includes rollers and a lever. The rollers are located on the upper surface of the pallet body 111 and can roll relative to the pallet body 111, thereby causing the product to move relative to the pallet body 111 on the rollers. The lever is located on the side of the pallet body 111, and the product can flow in and out of the pallet body 111 by moving the lever. Alternatively, the connecting conveyor assembly can be configured as a linear motor.

[0111] The upper surface of the pallet body 111 is provided with a receiving groove 115, and the connecting conveyor 112 is disposed in the receiving groove 115 so that the connecting conveyor 112 is located inside the pallet body 111, thereby hiding the height of the connecting conveyor 112 inside the pallet body 111. This helps to reduce the overall height of the helium detection cover 150 and the helium detection mechanism 6, thereby saving material costs and reducing the volume occupied by the machine.

[0112] Furthermore, the conveying surface of the connecting conveyor 112 (i.e., the upper surface of the connecting conveyor 112) protrudes from the upper surface of the pallet body 111. That is, the conveying surface is higher than the opening of the receiving groove 115 and the upper surface of the pallet body 111. In this way, when the product is on the helium inspection pallet 110, it will not contact the upper surface of the pallet body 111, but will directly contact the conveying surface of the connecting conveyor 112. The product is supported by the conveying surface, which can avoid contact friction between the product and the pallet body 111, thereby avoiding obstruction of the connecting conveyor of the product and further improving the stability of the product conveying.

[0113] It should be noted that the height of the conveying surface of the connecting conveyor 112 is close to the height of the upper surface of the pallet body 111, so that the difference between the two is small. Without affecting the product conveying, the connecting conveyor 112 and the pallet body 111 can have better integrity.

[0114] In the first embodiment, the connecting drive 113 is located on the outside of the receiving groove 115. When the tray body 111 is closed with the helium detector cover 150, the connecting drive 113 is located outside the sealed chamber, facilitating connection between the connecting drive 113 and the power supply and maintaining the stability of the power supply. Specifically, the fixing part of the connecting drive 113 is fixed to the outer wall of the receiving groove 115, and the driving part (i.e., the drive shaft) of the connecting drive 113 passes through the side wall of the receiving groove 115 and is connected to the connecting conveyor 112 located inside the receiving groove 115 to drive the connecting conveyor 112.

[0115] Furthermore, a sealing element 114 is provided between the driving part of the connecting drive member 113 and the side wall of the receiving groove 115. Specifically, the side wall of the receiving groove 115 is provided with a mounting hole, the driving part of the connecting drive member 113 passes through the mounting hole, and the sealing element 114 is also provided in the mounting hole and seals the mounting hole. In this way, under the action of the sealing element 114, the airtightness of the sealed chamber formed by the tray body 111 and the helium detection cover 150 during the helium detection process can be guaranteed, thereby ensuring the accuracy of the helium detection.

[0116] Here, the seal 114 can be configured to seal a magnetic fluid or a mechanical seal structure.

[0117] In the second scheme, the connecting drive is set in the receiving groove. When the tray body 111 is closed with the helium detector cover 150, the connecting drive 113 is located inside the sealed chamber, which has good sealing performance. Moreover, the connecting drive is equipped with a wireless charging module and / or a battery module. Through the design of the wireless charging module and the battery module, the power supply to the connecting drive can be realized, ensuring the stability of the power.

[0118] In the third scheme, the connecting drive is located outside the receiving groove and is connected to the connecting conveyor via a magnetic structure. Specifically, the first part of the magnetic structure is located inside the receiving groove and is connected to the connecting conveyor, while the other part is located outside the receiving groove and is connected to the connecting drive. The magnetic transmission between the first and second parts enables the connection between the connecting drive and the connecting conveyor, resulting in better sealing performance.

[0119] Combined with appendix Figure 4-8 The sealing nail welding inspection system includes a helium inspection mechanism 6, which includes a loading and unloading station, a helium inspection station, a switching track 120, and a switching drive assembly 130.

[0120] The loading and unloading station is located on the product conveying path to facilitate the loading and unloading of products. Here, the product conveying path is the path formed for conveying products when both ends of the helium inspection tray 110 are connected to the first conveyor line 100 and the second conveyor line 200 respectively. When both ends of the helium inspection tray 110 are connected to the first conveyor line 100 and the second conveyor line 200 respectively, the helium inspection tray 110 is in the loading and unloading station to facilitate the connection and conveying of the helium inspection tray 110 with the first conveyor line 100 and the second conveyor line 200 respectively.

[0121] The helium testing station is located at least on one side of the product transport path to facilitate helium testing. Specifically, a helium testing cover 150 and a helium testing drive assembly are positioned opposite the helium testing station. The helium testing drive assembly moves the helium testing cover 150 closer to and further away from the helium testing station. When the helium testing tray 110 is at the helium testing station, the helium testing drive assembly moves the helium testing cover 150 closer to the helium testing tray 110. The helium testing tray 110 and the helium testing cover 150 are connected to seal the product to be tested within a closed chamber, thereby completing the helium testing.

[0122] Here, the helium detection drive assembly includes a helium detection drive component 160 and a helium detection guide component 170. The helium detection drive component 160 (preferably a cylinder or hydraulic cylinder) can drive the helium detection cover 150 to move. The helium detection guide component 170 (specifically may include a guide rod and a bushing sleeved outside the guide rod) can guide the movement of the helium detection cover 150 to ensure that the helium detection cover 150 can accurately cover the corresponding position on the helium detection tray 110 and ensure the sealing effect.

[0123] Both the loading / unloading station and the helium inspection station are located on the switching track 120. The helium inspection tray 110 is set on the switching track 120 and can move along the switching track 120 to either the loading / unloading station or the helium inspection station, thereby switching the working state of the helium inspection tray 110. That is, when the helium inspection tray 110 is in the loading / unloading station, the loading and unloading processes are completed; when the helium inspection tray 110 is in the helium inspection station, the helium inspection process is completed. Specifically, the switching track 120 is set as a slide rail, and a slider is set at the bottom of the helium inspection tray 110. The displacement of the helium inspection tray 110 relative to the slide rail is achieved by the sliding displacement of the slider relative to the slide rail. Here, multiple slide rails are arranged in parallel (preferably two, but three or four can also be used) to ensure sliding balance.

[0124] The switching drive component 130 can drive the helium inspection tray 110 to move along the switching track 120, so that the helium inspection tray 110 can switch between the loading / unloading station and the helium inspection station. In this way, the position control of the helium inspection tray 110 can be realized through the switching drive component 130, which saves time and effort and helps to improve the level of automation.

[0125] Here, multiple helium inspection trays 110 are provided (preferably two, but also three or four), and they can be alternately located at the loading and unloading stations, so that multiple helium inspection trays 110 can alternately load and unload materials at the loading and unloading stations, which is beneficial to improving the efficiency of helium inspection.

[0126] With this configuration, multiple helium inspection trays 110 can be moved along the switching track 120 to switch between the loading / unloading station and the helium inspection station. This allows one helium inspection tray 110 to perform the loading / unloading process while another helium inspection tray 110 performs the helium inspection process, thereby improving the efficiency of helium inspection.

[0127] Correspondingly, multiple helium inspection stations are also provided (preferably two, but three or four are also possible). This creates multiple helium inspection stations on the switching track 120, and the helium inspection mechanism 6 forms a multi-station helium inspection configuration by matching and switching multiple helium inspection trays 110 with these stations, significantly improving work efficiency. Furthermore, the multiple helium inspection stations are positioned on opposite sides of the loading / unloading stations, which helps reduce displacement between the loading / unloading stations and the helium inspection stations, thus reducing waste.

[0128] Of course, a single helium inspection station can also be set up so that multiple helium inspection trays 110 can alternate between the loading / unloading station and the helium inspection station, which can avoid the impact between the helium inspection process and the loading / unloading process.

[0129] like Figure 7-8 As shown, the switching drive assembly 130 includes a switching drive component 131 and a switching connector 133. The switching drive component 131 has a switching part 132. When the switching drive component 131 is working, the switching part 132 can be displaced along the switching track 120. Specifically, the switching drive assembly 130 can be configured as a linear motor (or a cylinder or hydraulic cylinder). The switching part 132 is a platform that can be displaced under the drive of the linear motor. The switching connector 133 is disposed on the switching part 132 and can follow the switching part 132 to move along the switching track 120. The connection and disconnection between the switching drive assembly 130 and the helium detection tray 110 are realized through the connection and disconnection of the switching connector 133 and the helium detection tray 110.

[0130] Since there are multiple helium detection trays 110, and the switching connector 133 can be connected to and disconnected from any one of the helium detection trays 110, the switching drive component 130 can drive any one of the helium detection trays 110 to move along the switching track 120. In this way, any one of the multiple helium detection trays 110 can be driven individually through one switching drive component 130, which helps to save drive costs.

[0131] Of course, multiple helium detection trays 110 can also be driven individually through multiple switching drive components 130.

[0132] Specifically, the switching connector 133 is equipped with a telescopic pin 134, and the helium detection tray 110 is equipped with a pin hole that matches the telescopic pin 134. When the helium detection tray 110 is in the corresponding position, the telescopic pin 134 can extend into and out of the pin hole, thereby realizing the connection and disconnection between the switching connector 133 and the helium detection tray 110. That is, when the telescopic pin 134 is inside the pin hole, the switching connector 133 can drive the helium detection tray 110 to move along the switching track 120; when the telescopic pin 134 is outside the pin hole, the switching connector 133 cannot drive the helium detection tray 110 to move along the switching track 120. In this way, the connection and disconnection between the switching connector 133 and the helium detection tray 110 is achieved through the telescopic displacement of the telescopic pin 134, which is simple to operate, easy to control, and helps to save costs.

[0133] It should be noted that the telescopic pin 134 forms an angle with the displacement direction of the helium detection tray 110, preferably 90 degrees, so as to create an obstacle in the displacement direction of the helium detection tray 110 and drive the helium detection tray 110 to move.

[0134] Here, the switching connector 133 can be set as a pneumatic cylinder or a hydraulic cylinder, and the telescopic pin 134 is set as its telescopic end. Of course, it can also be set as a combination of a motor and a lead screw and nut mechanism.

[0135] The helium detection mechanism 6 includes a positioning component 140, which has a positioning part that can limit the displacement of the helium detection tray 110 along the switching track 120 to position the helium detection tray 110 at the helium detection station. In this way, the positioning of the helium detection tray 110 is achieved by controlling the position of the positioning part. The structure is simple and easy to process and program control.

[0136] The helium detection tray 110 is equipped with a clamping head and a positioning part is equipped with a clamping slot. The clamping head is positioned within the clamping slot by the displacement of the clamping slot.

[0137] Furthermore, the positioning component 140 also includes a support member and a slide cylinder. The support member can be fixed to the ground, a load, or a machine tool to achieve fixed support. Preferably, the support member is set as a column. The slide cylinder is set on the support member. The drive end of the slide cylinder is connected to the positioning part and drives the positioning part to move closer to or away from the helium detection tray 110.

[0138] Specifically, the positioning part is equipped with two rollers, forming the aforementioned bayonet between them. The two rollers can rotate relative to the positioning part to guide the insertion of the clamping head. When the clamping head and the bayonet are not fully aligned, the clamping head and the bayonet approach each other, and the end of the clamping head contacts the rollers on both sides of the bayonet. The rollers rotate and guide the clamping head into the bayonet, so that the bayonet and the clamping head are precisely positioned, improving the positioning accuracy.

[0139] This sealing nail welding inspection system includes a helium re-inspection mechanism 7, a reject conveyor line 8, and a transfer mechanism 9. The helium re-inspection mechanism 7 performs a re-inspection of the products. After the first helium inspection, if any products fail, they need to undergo a second helium inspection via the re-inspection mechanism 7, or vice versa, to ensure the accuracy of the helium inspection. The reject conveyor line 8 is used to transport products that fail the re-inspection by the helium re-inspection mechanism 7 to remove them. Specifically, it can be in the form of a drive belt or a double-speed chain. The transfer mechanism 9 is used to transfer products between the second conveyor line 200, the helium re-inspection mechanism 7, and the reject conveyor line 8, enabling the flow of products between these three systems. Specifically, the transfer mechanism 9 can be configured as a robotic arm structure.

[0140] In the case of a helium testing tray 110 that simultaneously carries multiple products for helium testing, if any one product in the same batch fails the helium testing on the tray 110, all products in the batch will be marked as unqualified. The helium testing re-inspection agency 7 will then conduct a re-inspection and screening of the multiple products in the batch to separate the qualified and unqualified products. The specific sorting and re-inspection method can be set to re-inspect one by one or to re-inspect using a binary method.

[0141] For example, if there are n products in the same batch, during the re-inspection, the n products are divided into two groups (each group has ½n products) and re-inspected separately. The qualified group is transferred to the second conveyor line 200 for unloading, and the unqualified group is again divided into two groups (each group has ¼n products) and re-inspected separately. The qualified group is transferred to the second conveyor line 200 for unloading, and the unqualified group continues to be divided and re-inspected, and so on, until all unqualified products are sorted out. The unqualified products are then sent to the rejection conveyor line 8 for rejection. In this way, the binary sorting method can reduce the number of re-inspections.

[0142] Thus, through the cooperation of the helium re-inspection mechanism 7, the reject conveyor line 8, and the transfer mechanism 9, a second helium inspection of the product can be achieved, which helps to improve the accuracy of the helium inspection and can separate qualified and unqualified products to ensure that qualified and unqualified products are transported separately, thus ensuring that all products fed in subsequent batches are qualified products.

[0143] Furthermore, the reject conveyor line 8 and the helium inspection re-inspection mechanism 7 are located on both sides of the second conveyor line 200, respectively. This reduces the transfer distance of the transfer mechanism 9 when transferring products, resulting in a shorter transfer path and improved work efficiency.
