[0102] On the basis of the above structure, the airtightness detection mechanism 1 and the taking and placing assembly 33 are respectively located on opposite sides of the transfer bottom plate 32.

[0103] The working process of the above structure is as follows: when the material 100 on the detection carrier 11 is being detected, the material 100 on the transfer carrier 4 is placed on the transition carrier 35 by the taking and placing assembly 33; when the detection of the material 100 on the detection carrier 11 is completed, the transfer driving assembly 34 drives the transfer bottom plate 32 to rotate 180°, so that the positions of the detection carrier 11 and the transition carrier 35 are exchanged; at this time, the original transition carrier 35 moves to the detection position and becomes a new detection carrier 11; then, the taking and placing assembly 33 transfers the material 100 that has been detected on the original detection carrier 11 to the transfer carrier 4; at this time, the original detection carrier 11 becomes a new transition carrier 35, ready for the next cycle. In the above structure, the automatic detection of the material is realized through the cooperation of the transfer carrier 4, the transfer bottom plate 32, the taking and placing assembly 33 and the transfer driving assembly 34; the setting of the transition carrier 35 can place the material 100 to be detected while the material 100 is being detected, realizing the flow detection work and greatly improving the detection efficiency of the device.

[0104] With reference to the above Figure 8 and Figure 9 , the taking and placing assembly 33 comprises a mounting seat 331 and at least one clamping structure 332, each clamping structure 332 is arranged on the mounting seat 331 and is used for clamping the material 100 to and from the transfer carrier 4 and the transition carrier 35.

[0105] Specifically, the taking and placing assembly 33 further comprises a fourth driving member 333 and a fifth driving member 334, wherein: the fourth driving member 333 is used for driving the mounting seat 331 to ascend and descend; the fifth driving member 334 is used for driving the mounting seat 331 to move between the transfer carrier 4 and the transfer bottom plate 32.

[0106] In the above structure, the at least one clamping structure 332 is arranged in one-to-one correspondence with the at least one containing groove 41. The mounting seat 331 and each clamping structure 332 are driven by the fourth driving member 333 and the fifth driving member 334 to move between the transfer carrier 4 and the transfer bottom plate 32, so as to move the material 100 to be detected on the transfer carrier 4 to the transfer bottom plate 32, or move the material 100 that has been detected on the transfer bottom plate 32 to the transfer carrier 4.

[0107] On the basis of the above structure, any clamping structure 332 comprises a clamping jaw and a sixth driving member for driving the clamping jaw to open or close.

[0109] In the embodiment, the third driving member 361 is specifically a pneumatic cylinder, and the piston rod end of the third driving member 361 can extend into or move out of the limiting groove. The outer side surface of the transfer carrier 4 is provided with a positioning hole, and the piston rod end of the third driving member 361 can be inserted into the positioning hole on the transfer carrier 4, thereby further preventing the transfer carrier 4 from being displaced.

[0110] When the transfer carrier 4 reaches the specified position, first, the piston rod end of the third driving member 361 penetrates through one of the limiting blocks 362 and extends into the limiting groove; then, the piston rod end of the third driving member 361 continues to extend into the limiting groove and is inserted into the positioning hole on the transfer carrier 4, thereby fixing the transfer carrier 4 between the piston rod end of the third driving member 361 and the other limiting block 362.

[0111] The number of third driving members 361 can be adjusted according to actual conditions, for example, the length of the transfer carrier 4; when the number of third driving members 361 is multiple, the multiple third driving members 361 are arranged in sequence along the length direction of the transfer carrier 4, thereby multiple-position positioning of the transfer carrier 4 can be realized, and the transfer carrier 4 can be prevented from shaking or being displaced.

Specifically, the transfer bottom plate 32 is in a disc type structure, the gear 341 and the transfer bottom plate 32 are coaxially arranged, and the transfer bottom plate 32 is driven to rotate through the gear-rack structure. Compared with directly using a rotary power member, the driving structure of the gear-rack is more space-saving, and is also convenient for positioning the transfer bottom plate 32 and improving the rotation accuracy of the transfer bottom plate 32.

[0113] In other embodiments, the transfer driving assembly 34 comprises a second driving member 343, the second driving member 343 has a rotatable output shaft, and the output shaft of the second driving member 343 is connected to the transfer bottom plate 32. Exemplarily, the second driving member 343 can be a rotary pneumatic cylinder, or an oil cylinder, or an electric cylinder; the output shaft of the second driving member 343 can be indirectly connected to the transfer bottom plate 32 through a connecting shaft, a gear, a belt wheel or the like, or can be directly connected to the transfer bottom plate 32; the above structures can all drive the transfer bottom plate 32 to rotate through the second driving member 343.

The buffer 312 and the block 311 are used for limiting, which can avoid the transfer base plate 32 from rotating excessively under the action of inertia, and ensure the rotation accuracy of the transfer base plate 32.

[0115] In the embodiment, the first driving member 123, the second driving member 343, the third driving member 361, the fourth driving member 333, the fifth driving member 334 and the sixth driving member are all set as air cylinders, so as to further reduce the manufacturing cost of the device.
