The structural part includes a base plate for supporting the product to be inspected, a pressure plate set on the base plate for pressing the product tightly against the base plate, a cylinder one for applying pressure to the pressure plate, a cylinder two for pushing out the product to be inspected, and a feeding device. In use, it can test multiple products simultaneously, with high testing efficiency. The setting of the sealing ring makes the testing accuracy high, and the setting of the limiting plate ensures that the product will not shake at will. It not only ensures the testing accuracy, but also makes the product loading and unloading quick and convenient, further improving the product testing efficiency. However, this technical solution uses the feeding device to clamp and pull back the sealing parts, and cannot place normal sealing parts on the placement plate according to the quality of the sealing parts, so that personnel need to rearrange them, increasing labor costs.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, a material feeding structure for testing the airtightness of metal seals includes a frame 1, on which a robotic arm 12, a conveyor belt 9, and at least one product placement plate 10 are mounted. The robotic arm 12 can place the metal seals on the conveyor belt 9 onto the product placement plate 10, which is placed on the frame 1. A batch conveying frame 4 is fixed to one side of the frame 1, and the bottom of the batch conveying frame 4 is also fixed with support legs that are in contact with the ground. The batch conveying frame 4 includes multiple placement openings and a funnel-shaped material plate. The funnel-shaped material plate is inclined and one end is located above the conveyor belt 9 so that the metal seals in the placement openings can slide onto the conveyor belt 9. Multiple rollers 5 located in the placement openings are rotatably mounted on the batch conveying frame 4. The rollers 5 are electrically driven to rotate so as to drive the metal seals into the funnel-shaped material plate.

[0022] The electric drive rotation of the roller 5 is specifically achieved by multiple rollers 5 being driven by pulleys and transmission belts, and one of the rollers 5 being connected to the motor via a pulley, with the motor fixed on the batch conveyor frame 4;

[0023] It should be noted that the connection between the pulley and the drive belt is existing technology, so it will not be described in detail here.

[0024] The frame 1 is also equipped with a clamping device for clamping metal seals, which can place the metal seals into the placement opening one by one;

[0025] When in use, the clamping device clamps the metal seals that have been tested and moves them to the top of the placement port. Then, according to the test results, the metal seals are dropped one by one into the placement port. After that, the roller 5 rotates and moves the metal seals one by one into the funnel-shaped material plate. After being moved by the funnel-shaped material plate, the metal seals fall onto the conveyor belt 9. The robotic arm 12 clamps the metal seals that have passed the test and places them on the corresponding product placement plate 10 according to the test results. The metal seals that fail the test are removed by the conveyor belt 9.

[0026] The other end of the conveyor belt 9 is equipped with a storage box, where metal seals that fail the inspection fall into the storage box.

[0027] In this embodiment, the product placement plate 10 includes two sets, front and back, each set consisting of two pieces arranged vertically. The frame 1 is provided with a product displacement component 11, and the product placement plate 10 is detachably connected to the product displacement component 11.

[0028] The product displacement assembly 11 includes multiple sets of linear displacement assemblies fixed on the frame 1. Each set of linear displacement assemblies consists of two parts and each set of linear displacement assemblies is fixed with a displacement plate 13. The displacement plate 13 is provided with a plug hole 15, and the product placement plate 10 is provided with a plug post 14 that is plugged into the plug hole 15.

[0029] The product placement plate 10 is secured by the cooperation of the plug post 14 and the plug hole 15, ensuring positioning while preventing the linear displacement component from shifting.

[0030] In this embodiment, a clamping displacement assembly 2 is provided on the frame 1, a displacement seat 3 is provided on the clamping displacement assembly 2, and the robotic arm 12 is disposed on the displacement seat 3.

[0031] During use, the clamping displacement component 2 drives the robotic arm 12 to move, ensuring that the robotic arm 12 can place the corresponding metal seal on the product placement plate 10.

[0032] In this embodiment, the outer ring of the roller 5 is fixedly sleeved with an elastic layer;

[0033] During use, an elastic layer provides cushioning to prevent damage to the metal seals when they fall.

[0034] In this embodiment, the clamping device includes a material feeding displacement component 8 disposed on the frame 1, a clamping plate 7 disposed on the material feeding displacement component 8, and a clamping cylinder 6 fixed on the clamping plate 7. The clamping cylinder 6 is located above the batch conveying frame 4 and the number is the same as the number of placement openings.

[0035] In use, the material feeding displacement component 8 drives the clamping plate 7 to move, and the clamping plate 7 drives the clamping cylinder 6 to move, thereby ensuring the movement of the clamping cylinder 6 and clamping the metal seal through the clamping cylinder 6, thus ensuring the transfer of the metal seal.

[0036] The clamping displacement assembly 2, the unloading displacement assembly 8, and the linear displacement assembly all consist of two electric slide rails and two electric sliders. The electric slide rails and electric sliders work together to move the corresponding displacement seat 3 and displacement plate 13.

[0037] Specifically, the electric slide rail and electric slider are equipped with a lead screw and a motor inside the electric slide rail, and a threaded block that engages with the lead screw thread. Displacement control is achieved through the engagement of the lead screw and the threaded block. Similarly, the electric slider and electric slide rail can also adopt other structures in the existing technology.

[0038] The electric slide rail and the frame 1, as well as the electric slider and the displacement seat 3, displacement plate 13 and clamping plate 7, can be fixed by existing bolts or other fixing methods.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
