Description

Technical Field

[0001] The utility model belongs to the technical field of braid stripping test, and in particular relates to a novel tensile force test instrument for braid stripping. Background Art

[0002] Taping is used to package bulk component products, with the carrier tape at the bottom and the cover tape at the top, to fix the components between the carrier tape and the cover tape. The tape needs to be tested for peeling tension to ensure that the carrier tape and the cover tape will not separate after the components are packaged, causing the components to scatter. When performing a peeling tension test on the tape, the lower tape and the upper cover tape at one end of the tape need to be separated, and the ends of the lower tape and the upper cover tape need to be fixed to the corresponding structure respectively, so as to facilitate subsequent tension testing.

[0003] In the related art, an automatic tester for the stripping tension of braid is disclosed, including a tensile gauge, a sensor, a tensile frame, a slide rail, a strip presentation platform, a motor, a lead screw, a display, and a controller. The tensile gauge is installed on the tensile frame, and a sensor is provided at one end of the tensile gauge close to the strip presentation platform. A display is provided on the left side of the tensile gauge, and the display is connected to the tensile gauge through a cable. A slide rail is provided on the right side of the tensile gauge, and a strip presentation platform is provided on the slide rail. A motor is provided on the left side of the slide rail, and the motor is connected to the slide rail through a lead screw. A controller is provided on the left side of the motor, and the controller controls the movement of the lead screw by controlling the motor, and drives the slide rail to move through the lead screw. The device has a reasonable design, a simple structure, and is easy to operate. The stripping of braid is performed by the movement of the slide rail, and the test results are accurate. The data can be well transmitted to a computer through the sensor.

[0004] However, the above structure still has some shortcomings. When the device is in use, it can only perform a 180° peeling test on the braid and cannot tighten and straighten the braid.
