Fig. 1 is a perspective view of a seal detection apparatus 100 according to an embodiment of the present invention. As shown in fig. 1, the present embodiment discloses a sealing detection device 100, which generally uses human eyes to determine the sealing qualification of a product 200, and the problem of this manual detection method is: the judgment error rate is high, namely, misjudgment is easy to occur, so that some unqualified products 200 flow to the market and some products 200 with good sealing are subjected to secondary sealing.

In order to improve the accuracy of judging whether the sealing of the product 200 is qualified or not, the following scheme is adopted: the sealing detection device 100 comprises a pressure container 30 and a laser machine 40, wherein the pressure container 30 comprises a container body 31 and a sealing cover 32, and the container body 31 is provided with a containing cavity 311 for containing a product 200. The laser machine 40 is configured to emit a radiation 41 toward the product 200 during the process in which the sealing cover 32 seals the container body 31 and the accommodating chamber 311 is filled with the air pressure, to detect the height change of the product 200.

The seal detection device 100 of the embodiment has the following beneficial effects: when the sealing cover 32 seals the container body 31 and the receiving cavity 311 is filled with pressure, if the product 200 is not sealed properly, a leakage of gas occurs, resulting in a change in the height of the product 200. If the product 200 is sealed properly, the height of the product 200 will not change. The embodiment detects the height change of the product 200 through the ray 41 emitted by the laser machine 40, and further determines whether the product 200 is sealed qualified, so that the detection precision is high, and further the detection accuracy of the sealing detection device 100 of the embodiment is high.

The seal detection apparatus 100 of the present embodiment further includes an inflation mechanism for inflating the accommodation chamber 311. For example, the inflation mechanism includes an air tube in communication with the receiving cavity 311.

The specific process of the sealing detection device 100 of this embodiment for detecting whether the product 200 is sealed qualified includes: 1) the sealing cover 32 is turned over to open the pressure container 30, and then the product 200 is placed in the receiving cavity 311. 2) The sealing lid 32 is turned over to close the pressure vessel 30. 3) Laser machine 40 moves over product 200 and emits radiation 41 toward product 200. 4) The accommodating chamber 311 is inflated until the air pressure reaches a preset value, and then pressure holding is performed. During the process from inflation to pressure holding, laser machine 40 detects whether the height of product 200 changes. The height here refers to the height in the vertical direction. 5) Finally, the pressure in the accommodating cavity 311 is released, and the laser machine 40 finishes detecting the product 200. The laser machine 40 is moved to the origin by a position adjustment mechanism hereinafter. 6) The sealing lid 32 is turned over to open the pressure vessel 30 and the product 200 is taken out of the containing chamber 311. 7) The seal-eligible products 200 may be placed in a bin and the seal-ineligible products 200 recovered for secondary sealing. And after secondary sealing, performing sealing detection.

As further shown in fig. 1, preferably, the number of the laser machines 40 of the present embodiment is at least two, and at least two laser machines 40 are respectively used for emitting the radiation 41 to at least two products 200. For example, the number of the laser machines 40 in this embodiment is 4, so that the sealing detection apparatus 100 in this embodiment can simultaneously detect whether the sealing of 4 products 200 is qualified or not at one time. In other embodiments, the number of laser machines 40 may also be 2, 3, 5, etc.

Fig. 2 is a perspective view of the pressure vessel 30 of the seal detection apparatus 100 according to the embodiment of the present invention. As shown in fig. 2, the pressure container 30 preferably further includes a support 312 located in the accommodating cavity 311 and a carrier 313 mounted on the support 312, wherein the carrier 313 is used for holding the product 200. The support 312 is horizontally disposed, and the carrier 313 is also horizontally disposed. The carrier 313 has the advantages that: the levelness of the product 200 can be improved, and the accuracy of detecting whether the sealing is qualified or not can be further improved.

Preferably, the carrier 313 has at least two receiving grooves for receiving the product 200. The tank bottom level of holding tank sets up. Preferably, at least two receiving grooves are distributed in an array. The advantage that sets up the holding tank lies in: the product 200 can be stably positioned in the accommodating cavity 311, and the accuracy of detecting whether the sealing is qualified or not is guaranteed. In addition, the receiving slots also facilitate placement and positioning of the product 200. For example, the number of the receiving grooves of the present embodiment is 4, and the 4 receiving grooves are arranged in two rows in the transverse direction and two rows in the longitudinal direction.
