Provided is a crimp terminal for alleviating manufacturing while maintaining waterproof property against a contact portion with an aluminum core wire. A barrel portion of a crimp terminal has an inner barrel piece and an outer barrel piece, and a seal member is provided for being stuck across a first region, a second region, and a third region, and after crimping for sealing a space between the inner barrel piece and the outer barrel piece, an opening of the barrel portion formed cylindrical on the terminal portion side, and a space between the covered portion and the barrel portion, and a plurality of recesses is dispersedly provided on an inner surface of the barrel portion so as to partly overlap with the seal member.

The present invention relates to a set of interchangeable crimp units for a crimping machine. According to the invention each crimp unit comprises an integrated sensor for measuring a crimping force or a crimping displacement during the crimping process.

Crimp tooling includes an anvil and a wire crimper. The anvil includes a base and a tip with a cradle at the tip for supporting a terminal. The anvil has first and second anvil guide surfaces located relative to the cradle. The wire crimper has first and second legs on opposite sides of a crimp slot that receives the cradle and the terminal supported by the cradle. The wire crimper defines a crimp profile in the crimp slot configured to form the terminal during crimping. The first and second legs have first and second wire crimper guide surfaces, respectively. The first and second wire crimper guide surfaces are configured to engage the first and second anvil guide surfaces, respectively, to guide a position of the wire crimper relative to the anvil.

The invention relates to a spunbond nonwoven laminate which is provided with a plurality of laminated spunbond nonwoven layers. At least two and at most four spunbond nonwoven layers have crimped continuous filaments. A degree of crimping of the filaments in each of the spunbond nonwoven layers is different from a degree of crimping in each of the other spunbond nonwoven layers and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments each having at least one first plastic component and at least one second plastic component. In addition, the invention also relates to a method and device for manufacturing the spunbond nonwoven laminate which is provided with a plurality of laminated spunbond nonwoven layers.

The invention discloses a high-precision stepped crimping hole processing method, which comprises the following steps: Step 1, punching a positioning hole; Step 2, measuring expansion and contraction for the first time; Step 3, positioning the first pin; Step 4, passing Mechanically drill through holes; step 5, perform controlled depth drilling to obtain controlled depth drilled holes, the depth of controlled depth drilled holes is the depth of the target conduction layer, and the controlled depth drilled holes are the inner diameter of the target through hole; step 6, sink copper; Step seven, electroplating; step eight, forming electroplating PIN holes after electroplating the positioning holes, and testing the size of electroplating PIN holes; step nine, positioning through the second pin nails and electroplating PIN holes matched with electroplating PIN holes; Drill to get backdrilled drill holes. The invention reduces the influence of positioning point deviation and improves the position accuracy of back drilling; the tool diameter of back drilling only needs to be increased by 0.025mm to 0.1mm relative to depth control drilling, which avoids the large diameter of conventional back drilling. The waste of space; the allowable deviation accuracy of the finished hole position is less than the copper thickness of the hole, ensuring that the crimping hole is a through hole.

The invention relates to an artificial intelligence-based evaluation method for hot-rolled steel coil crimp, which performs gray-scale processing on the initial steel coil image to obtain a gray-scale image; processes the gray-scale images respectively to obtain corresponding moiré pattern identification features 1 and 2. Moiré recognition feature 2, and obtain the initial moiré recognition index, when the initial moiré recognition index is greater than the set threshold, the area composed of pixels corresponding to the initial moiré recognition index is the initial moiré area; obtain different camera positions Steel coil image, segment and delete the steel coil image according to the initial moiré area, obtain the feature image, and extract the moiré area, calculate the steel coil curl evaluation value corresponding to the camera position according to the moiré area; according to the total value of the initial steel coil image The area and the obtained steel coil curl evaluation value of each camera position are used to calculate the current coil unwinding degree. That is to say, the present invention realizes the evaluation of steel coil crimp by detecting the moiré pattern, and improves the detection efficiency.
