Multiple material receiving seats 10 are shifted to positions corresponding to the connecting seats 30 in sequence under the rotation of the shift disk 20. The connecting seats 30 are moved to the corresponding material receiving seats 10 under the action of the power source. After the connecting seat 30 is connected with the material receiving seat 10, a sealing detection channel is formed.

[0026] Specifically, combined Figure 2 As shown, a hollow chamber 51 is formed in each pen cap 50, and a sealing ring 60 for sealing is installed on the top of the chamber 51. In practice, the sealing ring 60 can be made of silicone material, such as silicone beads. During the test, the pen cap 50 is carried on the material receiving seat 10, and the shape and size of the upper end of the material receiving seat 10 are matched with the chamber 51 of the pen cap 50. Since the pen cap 50 is hollow, the upper end of the material receiving seat 10 extends into the chamber 51 of the pen cap 50 and abuts against the sealing ring 60 in the pen cap 50.

[0027] A plurality of material receiving seats 10 are arranged on the shifting plate 20, and the plurality of material receiving seats 10 are generally evenly distributed along the circumferential direction of the shifting plate 20, and each material receiving seat 10 is used to bear a corresponding pen cap 50, and each material receiving seat 10 is vertically fixed on the shifting plate 20, so that the pen cap 50 is vertically carried on the material receiving seat 10. The shifting plate 20 rotates under the action of an external force, and the pen cap 50 on each material receiving seat 10 is sequentially transported to the sealing detection position through the rotation of the shifting plate 20. The sealing detection position in this embodiment is the position corresponding to the connecting seat 30.

[0028] A first sealing channel 11 is provided in each material receiving seat 10 .

In this embodiment, the power source includes a lifting seat 70 connected to the connecting seat 30. The connecting seat 30 is driven by the lifting seat 70 to move toward the direction close to the material receiving seat 10 until it is sealed to the material receiving seat 10; or to move away from the material receiving seat 10, leaving the material receiving seat 10 until it is reset. Because the material receiving seat 10 is vertically arranged, the connecting seat 30 here is driven by the lifting seat 70 to do the following: Figure 1 Movement in the up and down directions as indicated by the arrows.

[0030] A second sealing channel 31 is provided in the connection seat 30. In this embodiment, the second sealing channel 31 axially penetrates the connection seat 30, that is, penetrates the upper end and the lower end of the connection seat 30, and the upper end of the second sealing channel 31 is connected with the lower end of the first sealing channel 11 on the material receiving seat 10 after the connection seat 30 and the corresponding material receiving seat 10 are sealed and connected, forming a sealing detection channel penetrating the material receiving seat 10 and the connection seat 30, and the lower end of the second sealing channel 31 is connected to the vacuum detection mechanism 40. Among them, the upper end of the formed sealing detection channel (that is, the upper end of the first sealing channel 11) is connected to the sealing ring 60, and the lower end (that is, the lower end of the second sealing channel 31) is connected to the vacuum detection mechanism 40.

[0031] Preferably, a sealing layer 80 is further provided on the end surface of the connecting seat 30 in contact with the material receiving seat 10, for enhancing the sealing performance of the connecting seat 30 and the material receiving seat 10, and a silicone layer can be used for the sealing layer 80. In addition, a buckle ring 90 is further provided at the lower end of the shifting plate 20, for fixing the material receiving seat 10 on the shifting plate 20 after the material receiving seat 10 is installed on the shifting plate 20.

[0032] The vacuum detection mechanism 40 is connected to the connection base 30, and detects the sealing of the sealing detection channel to detect the sealing of the sealing ring 60 in the pen cap 50. Specifically, in this embodiment, the vacuum detection mechanism 40 includes a vacuum machine 41 and a vacuum detection meter 42, wherein the vacuum machine 41 is used to generate the negative pressure required for the detection, and is connected to the connection base 30 through a hollow connecting pipe 43, and the connecting pipe 43 is connected to the second sealing channel 31 in the connection base 30. The vacuum detection meter 42 is connected to the connecting pipe 43, and is used to detect the change of the vacuum value of the sealing detection channel and output information.

[0033] Preferably, a valve 32 is further provided between the connecting pipe 43 and the connecting seat 30 , for controlling the connection or closing between the second sealing channel 31 in the connecting seat 30 and the vacuum detection mechanism 40 .

[0034] During implementation, the present invention is not limited to being applicable to the sealing test of the sealing ring inside the pen cap, and other products that require sealing test can also be implemented using the solution of the present invention.

If there is a sealing ring 60 in the pen cap 50 and it is assembled correctly, the sealing ring 60 and the upper end of the material receiving seat 10 will also form a seal. At this time, the reading of the vacuum detection meter 42 will be within the normal range, indicating that the pen cap 50 has passed the test, otherwise, it is unqualified. After the test is completed, the valve is closed, and the connecting seat 30 is driven by the lifting seat 70 to move downward and reset, so that the current material receiving seat 10 is separated from the vacuum detection mechanism 40, and the shift plate 20 rotates to move the next pen cap 50 to the sealing detection position.

[0036] Based on the above-mentioned sealing detection device for the sealing ring inside the pen cap 50, a pen cap sealing detection method disclosed in an embodiment of the present invention comprises the following steps:

The connecting seat 30 moves upward under the drive of the lifting seat 70 until the sealing layer 80 at its upper end is sealed and connected with the lower end of the material receiving seat 10. After the connection, the second sealing channel 31 in the connecting seat 30 is connected with the first sealing channel 11 in the material receiving seat 10 to form a sealing detection channel.

[0039] S2, opening the vacuum detection mechanism 40 to detect the sealing performance of the sealing detection channel, so as to detect the sealing performance of the sealing ring 60.

[0040] Specifically, open the valve 32, and the vacuum detection mechanism 40 starts to work. If there is a sealing ring 60 in the pen cap 50 and it is assembled correctly, the sealing ring 60 and the upper end of the material receiving seat 10 will also form a seal. At this time, the reading of the vacuum detection gauge 42 will be within the normal range, indicating that the pen cap 50 has passed the inspection, otherwise, it is unqualified.

[0041] S3, after the detection is completed, the connecting seat 30 is disconnected from the material receiving seat 10 and reset under the action of the power source, and the next material receiving seat is moved to the sealing detection position driven by the shift plate 20 to perform the next pen cap detection.

[0042] Specifically, after the detection is completed, the valve 32 is closed, and the connecting seat 30 moves downward and resets under the drive of the lifting seat 70, so that the current material receiving seat 10 is separated from the vacuum detection mechanism 40, and the shift plate 20 rotates to move the next pen cap 50 to the sealing detection position, and the above steps S1 to S3 are repeated.
