It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of this application described herein.

[0038] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship recorded in the embodiments and shown in the drawings, or the orientation or positional relationship in which the product of this utility model is usually placed when in use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0039] As Figures 1 - 5 shown, the present utility model specifically relates to an automated handling line for helium leak detection of cylindrical shells, including a frame assembly 100, a handling assembly 200, a scanning assembly 300, a conveying assembly 400 and a helium leak detection assembly 500;

[0040] The rack assembly 100 includes a rack housing 110 and a rack base 120;

[0041] The handling assembly 200 is disposed on the rack base 120 and includes a bracket assembly 210, a loading manipulator assembly 220, a defective code scanning manipulator assembly 260, a helium leak detection handling manipulator assembly 230, a defective product handling manipulator assembly 240, and an unloading manipulator assembly 250. The loading manipulator assembly 220, the defective code scanning manipulator assembly 260, the helium leak detection handling manipulator assembly 230, the defective product handling manipulator assembly 240, and the unloading manipulator assembly 250 are respectively slidably connected to the bracket assembly 210;

[0042] The loading manipulator assembly 220 includes a loading pressing cylinder 221 and a loading pneumatic gripper 222 to transport a plurality of cylindrical shells to the code scanning assembly 300;

[0043] The defective code scanning manipulator assembly 260 includes a defective code scanning pressing cylinder 261 and a defective code scanning pneumatic gripper 262 to transport the cylindrical shells with abnormal code scanning;

[0044] The helium leak detection handling manipulator assembly 230 includes a helium leak detection handling pressing cylinder 231 and a helium leak detection pneumatic gripper 232 to transport the qualified cylindrical shells after code scanning to the conveying assembly 400, and through the conveying assembly 400, the cylindrical shells are sent to the helium leak detection assembly 500 for helium leak detection test;

[0045] The defective product handling manipulator assembly 240 includes a defective product pressing cylinder 241 and a defective product pneumatic gripper 242 to transport the cylindrical shells with abnormal helium leak detection;

[0046] The unloading manipulator assembly 250 includes an unloading pressing cylinder 251 and an unloading pneumatic gripper 252 to transport the qualified cylindrical shells after helium leak detection.

[0047] It should be noted that among them, the handling assembly 200, the code scanning assembly 300, the conveying assembly 400, and the helium leak detection assembly 500 are all disposed on the rack base 120, and the conveying assembly 400 and the helium leak detection assembly 500 cooperate with each other to transport the cylindrical shells to be tested to the helium leak detection assembly 500, and the helium leak detection assembly 500 performs helium leak detection test on the cylindrical shells.

[0048] In addition, the helium leak detection assembly 500 mainly completes the sealing test of the cylindrical shells before welding. The detection method is vacuum helium leak detection method. First, a certain amount of helium is filled into the cylindrical shells, and the sealing performance of the cylindrical shells before welding is determined by detecting the helium leakage amount within a certain period of time. The helium leak detection assembly 500 is a fully automatic device and is a relatively mature device in the prior art. Therefore, it will not be described in detail.

[0049] The bracket assembly 210 includes a gantry and multiple linear modules provided on the gantry. The multiple linear modules do not interfere with each other. The loading manipulator assembly 220, the defective code scanning manipulator assembly 260, the helium leak detection handling manipulator assembly 230, the defective product handling manipulator assembly 240, and the unloading manipulator assembly 250 are respectively connected to the gantry through linear modules. The above-mentioned manipulator assemblies all move within a specified stroke and will not interfere with each other.

[0050] First, the loading manipulator assembly 220 moves to a specified position through the linear module. The loading downward pressing cylinder 221 drives the loading pneumatic gripper 222 to move vertically downward, and clamps and fixes the cylindrical shell through the loading pneumatic gripper 222, and then transports the grabbed cylindrical shell to the code scanning assembly 300 to complete the code scanning and confirmation of the cylindrical shell.

[0051] The code scanning assembly 300 includes a linear translation module 320, a placement table assembly provided on the linear translation module 320, and a code reader 310 provided on one side of the placement table assembly.

[0052] Among them, the position of the gantry is fixed. When the placement table moves to a specified position through the linear translation module 320, the loading pneumatic gripper 222 moves synchronously and is located directly above the placement table, so that the loading downward pressing cylinder 221 and the loading pneumatic gripper 222 cooperate with each other to place the cylindrical shell on the placement table.

[0053] In addition, the position of the code reader 310 is fixed and unchanged. Therefore, during the code scanning process, the placement table assembly slowly moves through the linear translation module 320 so that the code reader 310 can read all the cylindrical shells on the placement table once.

[0054] The placement table assembly includes a tooling bracket 330, a plurality of positioning rotating shafts 340 provided at the end of the tooling bracket 330, and a driving motor 360 for driving the plurality of positioning rotating shafts 340 to rotate. One end of the positioning rotating shaft 340 is connected to the cylindrical shell, and the other end of the positioning rotating shaft 340 is connected to the driving motor 360 through a pulley assembly 350.

[0055] The tooling bracket 330 includes a bottom plate 331 connected to the linear translation module 320 and a bearing plate 333. A plurality of support columns 332 are connected between the bottom plate 331 and the bearing plate 333. The positioning rotating shaft 340 is rotatably connected to the bearing plate 333, and one end of the positioning rotating shaft 340 extends out of the upper end of the bearing plate 333 and can be connected to the cylindrical shell. The other end of the positioning rotating shaft 340 extends out of the lower end of the bearing plate 333 and is connected to the output end of the driving motor 360 through the pulley assembly 350. The driving motor 360 can drive the plurality of positioning rotating shafts 340 to rotate synchronously through the pulley assembly 350, thereby driving the cylindrical shell to rotate so that the code reader 310 can complete the code scanning work on the surface of the cylindrical shell.

[0056] The linear translation module 320 is a mechanism capable of driving the tooling bracket 330 to move linearly, which can be a guide rail, a lead screw, a linear guide rail 410, etc. The relevant structures and principles are easily understood by those skilled in the art, so no detailed description will be given here.

[0057] Further, eight positioning rotating shafts 340 are defined as a group, and there are two groups of the positioning rotating shafts 340.

[0058] Among them, one group of positioning rotating shafts 340 is the group being scanned, and the other group is the group to be scanned. By setting two groups, the scanning efficiency can be improved.

[0059] When the cylindrical shell is scanned and confirmed to be abnormal, the defective scanning manipulator assembly 260 moves to the scanning assembly 300 through the linear module. At this time, the placement table reaches the designated position through the linear translation module 320, and the defective scanning pressing cylinder 261 drives the defective scanning pneumatic gripper 262 to clamp and carry the defective scanned cylindrical shell.

[0060] In addition, each manipulator assembly is provided with a sensor to detect whether an item exists, which belongs to conventional technical means and will not be described in detail here.

[0061] When the cylindrical shell is scanned and confirmed to be okay, the helium leak detection handling manipulator assembly 230 clamps and fixes the scanned cylindrical shell on the placement table.

[0062] The helium leak detection handling manipulator assembly 230 moves to the placement table area through the linear module. The helium leak detection pressing cylinder 231 and the helium leak detection pneumatic gripper 232 cooperate with each other to clamp and fix the cylindrical shell, and carry the cylindrical shell to the conveying assembly 400;

[0063] The linear translation module 320 is arranged in parallel with the conveying assembly 400.

[0064] There are multiple groups of the conveying assembly 400, and there are multiple groups of the helium leak detection assembly 500. The multiple groups of the conveying assembly 400 and the helium leak detection assembly 500 correspond to each other one by one.

[0065] The multiple groups of helium leak detection assemblies 500 and the multiple groups of conveying assemblies 400 cooperate with each other to be able to perform helium leak detection on multiple groups of cylindrical shells simultaneously, improving the detection efficiency.

[0066] The conveying assembly 400 includes a linear guide rail 410 arranged on the frame base 120 and a tooling 420 slidably connected to the linear guide rail 410 and for placing the cylindrical shell.

[0067] The tooling 420 moves to the designated position through the linear guide 410. At this time, the helium leak detection pneumatic gripper 232 is located directly above the tooling 420. Through the cooperation of the helium leak detection handling and pressing cylinder 231 and the helium leak detection pneumatic gripper 232, the cylindrical shell is placed on the tooling 420.

[0068] The tooling 420 then moves to the helium leak detection assembly 500 through the linear guide 410 to complete the helium leak detection test on the cylindrical shell placed on the tooling 420.

[0069] After the helium leak detection test is completed, if there is an abnormal sealing situation in the cylindrical shells tested this time, the abnormal cylindrical shells are transported to the retest channel (not marked in the figure) by the blanking manipulator assembly 250. Wait for the defective product handling manipulator assembly 240 to transport the cylindrical shells to be retested in the retest channel to the re-inspection station (not marked in the figure). If there are still abnormalities during the re-inspection process, the defective products will be carried out by the defective product handling manipulator assembly 240.

[0070] If all the cylindrical shells tested this time are qualified products, the cylindrical shells on the tooling 420 are transported by the blanking manipulator assembly 250.

[0071] The specific handling process is the same as that in the above text, so it will not be described in detail here.

[0072] The structures of the loading manipulator assembly 220, the helium leak detection handling manipulator assembly 230, and the blanking manipulator assembly 250 are the same; the structures of the code scanning defective manipulator assembly 260 and the defective product handling manipulator assembly 240 are the same.

[0073] The structures of the loading pneumatic gripper 222 and the code scanning defective pneumatic gripper 262 are the same.

[0074] The loading manipulator assembly 220 is provided with multiple groups of the loading pneumatic grippers 222.

[0075] The above embodiments are only specific implementation manners of the present invention, used to illustrate the technical solutions of the present invention, rather than limiting it. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: any person skilled in the art within the technical scope disclosed by the present invention can still modify the technical solutions recorded in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered within the protection scope of the present invention.
