The application relates to a sensor film pasting jig, which comprises a base, a containing cavity for placing a product and a cutting groove are formed in the base, a suction hole is formed in the bottom of the containing cavity, a vacuum channel is formed in the base, the vacuum channel is communicated with the suction hole, an insert is mounted in the cutting groove, a notch is formed in the insert, the hardness of the insert is greater than that of the base, in use, the product is placed in the containing cavity, the product abuts against the side wall of the containing cavity, and the product is fixed by suction through the suction hole. The film pasting jig can simultaneously realize sensor cutting and film pasting and cap film pasting, one set of mold cost is saved, the mold does not need to be replaced, and manpower is saved.

The utility model discloses an environment-friendly tail gas treatment device for N, O-bis (trimethylsilyl) acetamide production, which belongs to the technical field of tail gas treatment and comprises a filter box, one side of the filter box is fixedly connected with a first pipeline, two filter plates are clamped on the filter box, and filter screens are fixedly connected on the filter plates. According to the tail gas environment-friendly treatment device for N, O-bis (trimethylsilyl) acetamide production, when a filter plate is replaced, after an operator holds a rubber sleeve, the rubber sleeve is pulled to move, the rubber sleeve drives a connecting rod to slide in a second sliding groove, the connecting rod drives a clamping block to slide in a first sliding groove, and a spring is contracted until the clamping block is completely separated from the filter plate; and an operator pulls out and replaces the filter plate, so that the operator can conveniently and quickly replace the filter plate, the situation that a large amount of solid waste is attached to a filter screen on the filter plate due to long-term use of the filter plate, and consequently the filtering efficiency of the treatment device is reduced is prevented, and the functionality of the treatment device is improved.
