The invention discloses a full-automatic intelligent fish skin cutting and stripping method. The method is implemented based on a fish skin stripping device. The fish skin stripping device comprises a clamping mechanism, an annular cutting knife (1), a separating knife (2) and a peeling mechanism (3). The clamping mechanism comprises a gill hook (4) and a tail clamp mechanism (5), the annular cutting knife is located at the eccentric position of the central axis between the gill hook and the tail clamp mechanism, and the separating knife and the peeling mechanism are located on the gill hook side. The fish skin cutting and stripping method includes the following steps of clamping, recognizing and scanning, annular cutting, fish skin separating, longitudinal cutting and peeling. By means of the method, fish skin is automatically separated, the fish skin stripping efficiency is improved, it is avoided that fish skin is damaged, and interference of the knives is avoided.

The invention relates to an automatic crab trap releasing device. Problems of great labor intensity, high cost and low efficiency caused by manually releasing the traditional crab trap are mainly solved. The automatic crab trap releasing device comprises a fixed seat and an unhooking device, wherein a lifting hook comprises a clamping part and a releasing part; a crab trap is connected with a supporting rope through the lifting hook; the unhooking device is hinged on the fixed seat; the unhooking device comprises a bottom plate, a stopping plate and a stopping block; a unhooking slot is formed in the bottom plate; the unhooking slot comprises a sliding-in end and a releasing end; the stopping block is fixedly connected with the bottom plate; a clamping slot is formed in the stopping block; the lifting hook is in clamping fit with the clamping slot; the supporting rope is connected with the releasing part; the releasing part of the lifting hook is pulled by the supporting rope to slide into the unhooking slot; the clamping part of the lifting hook is pushed in the clamping slot so as to drive the unhooking device to rotate for a certain angle around a hinging center; the supporting rope is separated from the lifting hook through a rope releasing opening; and the lifting hook is released from the unhooking device. As the releasing device can be used for releasing the crab trap, the automatic crab trap releasing device provided by the invention is advantaged in that the labor intensity of the releasing device is low, the cost of the device is saved, the production effect of the device is extremely high, and automatic separation is effectively realized.

The invention relates to the field of mechanical welding, in particular to a robot resistance spot-welding technological parameter testing and control method. The robot resistance spot-welding technological parameter testing and control method comprises the steps that S1, measuring position transfer verification is carried out; S2, empty spot welding is carried out; S3, actual measurement is carried out; S4, a program position output parameter of the S2 and an actual position output parameter of S3 are subjected to parameter linearization; and S5, a technological parameter setting value is verified. The robot resistance spot-welding technological parameter testing and control method has the following beneficial effects that according to the technical scheme, the robot resistance spot-welding technological parameter testing and control method comprises empty spot and practical spot welding parameter comparison verification, so that the parameter output conformability of the parameters on the two situations is ensured; a fixing bracket of a welding testing instrument is designed and manufactured, so that artificial participation is reduced, and the operational safety performance is improved; a welding test piece fixing bracket is designed and manufactured, so that the history that a welding test piece can not be verified is ended; robot parameter definitions are increased, and welding current and welding pressure test automation separation is realized; and a robot program is designed and written, so that the operational flexibility is ensured, and personnel participation is reduced.

A preparative circulating chromatography apparatus can be applied in chromatographic separation preparation of target components in a complex sample and is mainly advantaged in that: (1) with pre-treatment and concentration of an on-line sample, large-volume sampling on the premise of a high column efficiency can be achieved; (2) through position exchange between a separation column and a trapping column, circulating separation and purification of the target components are achieved and the preparative circulating chromatography apparatus is less in circulating dead volume and column efficiency loss; and (3) through concentration-elution of a finish product through the trapping column, a separation-concentration integrated process is achieved, wherein the three functions are achieved through adjustment of an adsorption performance of the trapping column and valve exchange. Compared with a conventional preparative chromatography method, the apparatus has significant advantages on separations of natural products, drugs and chemical products, especially on separation and preparation of micro-scale targeted components and unstable components in a mixture.

The invention discloses a full-automatic fish skin separating method based on a fish skin separating device. The fish skin separating device comprises a clamping mechanism, a girdling knife (1), a separating knife (2) and a skinning mechanism (3), wherein the clamping mechanism comprises a fish gill hook (4) and a tail clamping mechanism (5); the girdling knife is located at the eccentric position of the central axis between the fish gill hook and the tail clamping mechanism; the separating knife and the skinning mechanism are located on the side of the fish gill hook; three-dimensional image scanning is performed on a fish body to obtain the annular cutting position and path, the separating path, the longitudinal cutting path and the skinning path; the fish body to be skinned is horizontally clamped by the clamping mechanism in tandem, the girdling knife conducts annular cutting around the fish body, the separating knife extends into the fish body from the incision at the annular cutting part to separate the fish skin from the fish body, then the girdling knife longitudinally cuts the fish skin in the length direction of the fish body, and the tail clamping mechanism releases in the skinning process of the skinning mechanism. The full-automatic fish skin separating method realizes automatic fish skin separation, improves the fish skinning efficiency and prevents the fish skin from being broken.
