Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a belt pulling-down test mechanism. Background Art

[0002] At present, in the production process of products such as semiconductor chips, the tray is a "material tray" for carrying workpieces to run on the production line, and is widely used in the packaging and transportation of electronic components, which can protect the components from damage during transportation. Its specifications are generally 2 inches, 3 inches, and 4 inches.

[0003] After the workpieces such as electronic components are loaded into the corresponding specification trays, it is necessary to band the stacked trays with plastic belts to prevent the trays from scattering due to factors such as vibration during transportation. Therefore, after the trays are banded, it is necessary to detect the quality of the bands to ensure that the bands will not break during transportation. The existing technologies basically use the method of manually pulling the bands to check the quality of the bands, but the pulling force and angle of manual detection cannot be accurately controlled, resulting in inaccurate detection results, and manual detection takes a long time, resulting in low efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a belt pulling-down test mechanism, which includes a horizontally arranged bottom plate. Support rods are symmetrically arranged on the bottom plate. A carrier is arranged at the top of each support rod for carrying the tray with the belt to be tested. Force sensors are arranged between the carrier and the two support rods.

[0005] A pressing module for pressing the tray on the carrier is further arranged on the bottom plate.

[0006] A pulling-down module for pulling down the plastic belt of the tray on the carrier is further arranged on the bottom plate.

[0007] Among them, the pressing module includes an L-shaped support frame arranged on the bottom plate, a lower piezoelectric cylinder installed on the horizontal plate of the L-shaped support frame, and a pressing block arranged at the telescopic end of the lower piezoelectric cylinder. The pressing block is vertically located above the carrier.

[0008] Among them, the pressing module further includes a lower pressing limit induction sheet arranged on the side of the telescopic end of the lower piezoelectric cylinder, and a lower pressing lower sensor and a lower pressing upper sensor correspondingly arranged on the side of the L-shaped support frame and corresponding to the lower pressing limit induction sheet for defining the upper and lower limits of the extreme lifting of the pressing block.

[0009] Among them, a lower pressing lower sensor corresponding to the carrier is installed on the side of the L-shaped support frame.

[0010] Among them, the pulling-down module includes a pulling-down electric cylinder arranged on the lower side of the bottom plate, a support frame that is vertically movable through a guide post on the upper side of the bottom plate and is driven by the pulling-down electric cylinder to move up and down, a rotary cylinder installed on the support frame, a turntable rotatably arranged on the support frame and driven by the rotary cylinder to rotate, and clamping jaws symmetrically arranged on the turntable.

[0011] Among them, the pulling-down module further includes a pulling-down limit induction sheet horizontally arranged on the side of the support frame, and a pulling-down lower position sensor and a pulling-down upper position sensor installed on the side of the support rod corresponding to the pulling-down limit induction sheet for defining the upper and lower limits of the extreme lifting of the clamping jaws.

[0012] Through the above technical solution, the strap pulling-down test mechanism provided by the present utility model is used for detecting the quality of the strap after the tray is strapped. After the tray arrives, the strapped tray is pressed and fixed by the pressing-down module, and then the plastic strap is clamped and pulled down by the pulling-down module, and the actual pulling force is fed back through a force sensor. If the plastic strap does not break when the standard value is exceeded, it is qualified. It can be adjusted to be applicable to the tests of strapping trays of various different specifications such as 2-inch, 3-inch, and 4-inch trays, and has the characteristics of stability, reliability, and high compatibility, and can effectively detect the quality problem that the strap is likely to break due to poor strap quality after strapping.

[0018] Among them, the pressing module includes an L-shaped support frame 11 arranged on the bottom plate 10, a piezoelectric cylinder 12 installed on the horizontal plate of the L-shaped support frame 11, and a pressing block 13 arranged at the telescopic end of the piezoelectric cylinder 12.

[0022] Then, after the tray 30 on the loading platform 18 is in place, the piezoelectric cylinder 12 drives the pressing block 13 to press down and presses the tray 30 on the loading platform 18.

[0023] Then, after the pulling-down cylinder 19 drives the support frame 21 to rise to a specified height, the rotary cylinder 22 drives the turntable 23 to rotate so that the clamping jaws 25 rotate and clamp the plastic belt 31.
