5results about How to "Guaranteed Screening" patented technology

This utility model belongs to the field of medical device testing technology, specifically relating to a fixture for testing the release force of an injection activator and a testing device using the same. The fixture includes: a barb component comprising at least two barb protrusions adapted to be simultaneously inserted into the injection activator; at least two flexible arms of the barb component, each corresponding to a barb protrusion and connected to one end of a flexible arm; and a base connected to the other end of each flexible arm, wherein the base is adapted to be placed in a testing machine. The fixture and testing device using the same utilize the deformation of the flexible arms of the barb component to insert and fix the barb protrusions into the injection activator. Simultaneously, the base of the barb component places the entire fixture into the testing machine for accurate release force testing, thereby ensuring the production or screening of qualified products.

This utility model relates to the field of tea processing and discloses a tea sorting device, including a casing, a feeding port, a waste conveying port, a cylinder, a left vertical plate, a right vertical plate, a sieve plate, a fixed plate, a partition plate, a waste conveying plate, an abutment plate, a vibrating motor, and an auxiliary turning assembly. In use, initially, the cylinder piston rod extends, causing the abutment plate to contact the fixed plate and the sieve plate, enclosing the tea in the sieving space. The tea is fed vertically from the feeding port through the material passage into the sieving space. The vibrating motor is activated, causing the sieve plate to vibrate and disperse the tea. Impurities are shaken onto the waste conveying plate and output from the waste outlet. The auxiliary turning assembly is activated to continuously agitate and turn the tea. After sieving, the cylinder piston rod retracts, opening the sieving space. The vibrating motor continues to vibrate, causing the tea to fall through the space for air separation, thus achieving the tea sorting process. This utility model has the advantages and effects of thorough tea sorting, high efficiency, and wide adaptability.

The utility model relates to the technical field of epidemic wood treatment, in particular to epidemic wood crushing and worm egg killing integrated equipment, which comprises a box body, two crushing rollers, a first crushing roller, a second crushing roller, a third crushing roller and a fourth crushing roller, the first frame body is arranged in the box body in a sliding manner, and a filter screen is fixed in the first frame body; the first frame body is arranged in the box body in a sliding mode, the second frame body is arranged in the box body in a sliding mode, a plurality of connecting rods are arranged on the second frame body, and each connecting rod is fixed to the first frame body. According to the device, the filter screen is arranged, so that the epidemic wood powder falling on the filter screen can be screened by the filter screen, the small-particle epidemic wood powder falling below the filter screen is in contact with the liquid medicine output by the spraying assembly, the work of killing the worm eggs in the epidemic wood is realized, the worm eggs hidden in the large particles are left on the filter screen to wait for next crushing, and the worm egg killing effect is ensured.

The application relates to a memory chip early storage failure screening method and a test system. The screening method comprises the following steps: acquiring first voltage data of all chips on a wafer; establishing a first voltage data distribution curve; screening out failure chips and high-risk chips with a first dispersion degree; establishing a distribution hotspot map of the first voltage data on the wafer; determining a high-risk area in the failure chips and the high-risk chips; performing reliability test on the high-risk chips and the chips in the high-risk area, and acquiring second voltage data of the chips after the test; determining unqualified chips according to the second voltage data; and determining a target card control value according to the first voltage data of the unqualified chips, which is used for early failure screening of wafer chips in the same batch. The test system is based on the above screening method and comprises a voltage data acquisition module, a reliability test module, an analysis and calculation module and a screening module. The application can realize more efficient and comprehensive early storage failure screening.

The application relates to the technical field of cement raw material grinding particle size measurement, and discloses a ball mill cement raw material grinding particle size measurement system and a measurement method thereof, which comprises a detection box, a rotary transmission unit and a rotary detection unit, a feeding hopper is vertically and penetratively arranged on the detection box; a servo motor is arranged in the inner cavity of the detection box, a six-sided box is connected with the servo motor in a power mode, an upper tooth plate and a lower tooth plate which are mutually attached are movably arranged in the six-sided box, and six side walls of the six-sided box are movably arranged. After data collection is accepted, the servo motor continues to work to drive the six-sided box to rotate, the two follow-up rods can be driven to rotate in the rotating process of the six-sided box, so that the filter cylinder and the collecting cone cylinder can be driven to rotate vertically downward to discharge powder; the powder is discharged under the action of a flow guide inclined table, when the six-sided box rotates, the outer gear ring drives the transmission gear to rotate, so that the blowing impeller is driven to rotate to blow air to ensure the cleanliness of the filter cylinder and the collecting cone cylinder.
