Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a strap pull-up testing mechanism. Background Art

[0002] At present, in the production process of semiconductor chips and other products, trays are the "material trays" that carry workpieces on the production line. They are widely used in the packaging and transportation of electronic components. They can protect components from damage during transportation. Their specifications are generally 2 inches, 3 inches, and 4 inches.

[0003] After electronic components and other workpieces are loaded into trays of corresponding specifications, multiple stacked trays need to be strapped with plastic tape to prevent the trays from opening due to vibration and other factors during transportation, resulting in the trays scattering and other defects. Therefore, after the trays are strapped, the quality of the straps needs to be tested to ensure that the straps will not break during transportation. The existing technology basically uses manual strapping to check the quality of the straps, but the manual inspection of the strapping force and angle cannot be accurately controlled, resulting in inaccurate inspection results, and manual inspection takes a long time, resulting in low efficiency.

[0009] Through the above technical scheme, the utility model provides a drawstring pull-up test mechanism, which is used to detect the quality of the drawstring after the tray is strapped. After the tray is in place, the strapped plastic belt is sucked up by a suction cup, and the actual tension is fed back through a tension sensor.

[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] refer to Figure 1 The present embodiment provides a strap pull-up test mechanism, comprising a horizontally arranged bottom plate 10, a supporting side plate 11 symmetrically and vertically installed on the bottom plate 10, a top plate 25 horizontally installed above the supporting side plates 11 on both sides, slide rails 12 symmetrically arranged on the inner sides of the supporting side plates 11, a loading assembly installed on the slide rails 12, and a pull-up assembly installed on the top plate 25 and located above the loading assembly.

[0015] Among them, the loading assembly includes a support block 13 symmetrically and slidably installed on the inner side of the slide rails 12 on both sides, a rodless cylinder assembly 14 horizontally arranged between the support blocks 13 on both sides, and a carrier 15 slidably arranged on the rodless cylinder assembly 14; the loading assembly also includes a height limiting plate 16, the height limiting plate 16 is horizontally installed between the slide rails 12 on both sides to limit the height between the height limiting plate 16 and the carrier 15 according to the height of the tray 30, and the height limiting plate 16 is provided with a avoidance groove 161 corresponding to the upper pull-up assembly.

[0016] Among them, the pulling-up component includes an electric cylinder 20 vertically installed on the top plate 25, a lifting slide 18 driven by the electric cylinder 20 and slidably installed between the two side slide rails 12, and a suction cup 19 installed on the lower side of the lifting slide 18, a tension sensor 24 is arranged between the suction cup 19 and the lifting slide 18, and the suction cup 19 is located above the carrier 15 for the adsorption and pulling test of the plastic belt 31 on the tray 30; the pulling-up component also includes a lifting limit block 21 arranged on the inner side of the slide rail 12 and located above the lifting slide 18, a lower sensor 17 and an upper sensor 23 installed on the side of the supporting side plate 11, and a lifting sensor sheet 22 installed on the lifting slide 18 and corresponding to the lower sensor 17 and the upper sensor 23 for lifting limit sensing of the suction cup 19.

[0017] The working principle of this embodiment:

[0018] First, according to the height of the tray 30 to be tested of different specifications after being strapped, the support block 13 is driven by an electric cylinder to slide and rise along the slide rail 12, so that the tray 30 after being strapped fits the height limit plate 16 above;

[0019] Then, the platform 15 is driven to slide out by the rodless cylinder assembly 14, and the tray 30 with the tested belt is placed on the platform 15 by a manual rear manipulator or the like, and then the platform 15 is driven to move to the bottom of the height limit plate 16 by the rodless cylinder assembly 14;

[0020] After the in-position sensor 17 senses that the tray 30 is in position, the electric cylinder 20 drives the lifting slide 18 to descend and then drives the suction cup 19 to descend to the avoidance groove 161 provided on the corresponding height limit plate 16, and then the suction cup 19 absorbs the plastic belt 31 on the tray 30 and senses whether the suction cup 19 is in position through the in-position sensor 17;

[0021] Finally, the electric cylinder 20 drives the lifting slide 18 to rise and then drives the suction cup 19 to rise to the specified height to realize the suction and pull-up test of the plastic belt 31 on the tray 30 and feedback the actual tension through the tension sensor 24, and the lower sensor 17 and the upper sensor 23 correspond to the lifting sensor sheet 22 to determine the maximum lifting height of the suction cup 19 and the lifting limit block 21 to limit the lifting height;

[0022] At the same time, according to the actual tension fed back by the tension sensor 24, if it exceeds the standard value and the plastic belt 31 does not break, it is judged to be qualified; this mechanism can be adjusted to be suitable for testing the straps of various specifications of trays 30 such as 2 inches, 3 inches, and 4 inches. It has the characteristics of stability, reliability, and high compatibility, and can effectively detect quality problems such as easy disconnection due to poor quality of the straps.
