Description

Technical Field

[0001] This utility model relates to the field of strain gauge load cell placement machine, specifically to an automatic strain gauge load cell placement machine. Background Technology

[0002] A strain gauge load cell is a device that detects weight or force by measuring the deformation of an elastic body. Its core principle is based on the strain effect (the change in resistance caused by the deformation of a material under force). It is one of the most commonly used sensor types in industrial weighing and force measurement. A strain gauge load cell includes an elastic body, strain gauges, circuitry, and a housing.

[0003] Because of their thin and lightweight structure, strain gauges are typically attached and positioned using a base film with a certain degree of adhesion during the manufacturing process. Before assembling the strain gauge onto the strain gauge load cell, it needs to be removed from the base film and placed on a rack to facilitate subsequent processing.

[0004] However, existing automatic patching machines for strain gauge load cells are inconvenient for removing strain gauges from the base film; when removing strain gauges from the base film, their positions on the plane sometimes shift, and strain gauges that shift in position on the plane cannot be accurately placed on the rack.

[0005] The purpose of this invention is to design an automatic patching machine for strain gauge weighing sensors to address the problems existing in the prior art. Utility Model Content

[0022] Therefore, the present invention provides the following effects and / or advantages:

[0023] 1) The frame is used to support components and to place the automatic patcher stably on the ground; the loading rack is used to load a base film with several strain gauges attached, the strain gauges being longitudinally attached to the base film; the detection device is used to identify and record the position of the strain gauges on the plane after the loading rack loads the base film with several strain gauges attached; the placement rack is used to place the strain gauges removed from the base film loaded by the loading rack; the pick-and-place device is used to remove at least one strain gauge from the base film loaded by the loading rack each time.

[0024] The scraping device is used to scrape each strain gauge to be removed before the lifting and placing device removes at least one strain gauge from the bottom membrane loaded on the loading frame. The scraping process involves first pushing the bottom membrane at the strain gauge to be removed up a predetermined vertical distance and then scraping it a predetermined distance in a predetermined direction, so that the lifting and placing device can remove the strain gauge from the bottom membrane loaded on the loading frame.

[0025] The removal and placement device is used to move at least one strain gauge to the calibration device for calibration after each removal of at least one strain gauge from the bottom membrane loaded by the loading frame.

[0026] The calibration device is used to identify the position of at least one strain gauge carried by the take-up and put-down device on the plane, and compare it with the data recorded by the detection device, so as to check whether the position of each strain gauge carried by the take-up and put-down device on the plane has shifted.

[0027] The take-up and put-down device is used to correct and reset at least one strain gauge carried by the take-up and put-down device that has been detected by the calibration device as having a positional deviation on the plane, and then move at least one strain gauge to the top of the placement rack and place it on the placement rack; the take-up and put-down device is used to move at least one strain gauge to the top of the placement rack and place it on the placement rack when the calibration device has detected that the positional deviation of each strain gauge carried by the take-up and put-down device on the plane has not occurred.

[0028] In summary: it facilitates the removal of strain gauges from the base film; even if the strain gauge's position on the plane shifts during removal, it can be corrected and reset, thus ensuring that the strain gauge removed from the base film can be accurately placed on the display rack.

[0029] 2) The third XY linear module is used to drive the placement frame to a predetermined position after the pick-and-place device places at least one strain gauge on the placement frame each time, so that the pick-and-place device can place the strain gauge next time.
