In one aspect of the present embodiment, a sliding sleeve 20 is disposed at a corner of the working platform 11, the sliding sleeve 20 is slidably connected to a sliding rod 21, and an end of the sliding rod 21 is fixedly connected to the lifting plate 1. The control of the lowest position of the lifting plate 1 is realized by arranging the sliding sleeve 20, so that the precision of the second air cylinder 23 is reduced, the second air cylinder 23 only needs to be controlled to extend and contract, and the specific position is controlled by the height of the sliding sleeve 20. The middle part of the workbench 11 is in threaded connection with a screw rod 16, and one side of the screw rod 16 close to the push plate 13 is provided with a top plate 17 matched with the push plate 13. The top plate 17 also limits the lowest height of the push plate 13, so that the first air cylinder 19 only needs to control stretching, and the position of the top plate 17 can be adjusted due to the arrangement of the screw rod 16, so that the effect of adjusting the lowest position of the push plate 13 can be realized, namely, the adjustment of detecting the thickness of the silica gel pad is realized, and the rotating wheel 18 is arranged at the lower end of the screw rod 16, so that the rotation of the screw rod 16 is convenient.
First place this device stable on the desktop, start first cylinder 19 and second cylinder 23, first cylinder 19 and second cylinder 23 contract completely, spacing 14 inserts in spacing hole 8 this moment, and realize adjusting the height of spacing 14 through rotatory lead screw 16, make the height of the height distance lifter plate 1 upper surface of spacing 14 upper end just be the thickness of silica gel pad, also be exactly the silica gel pad can not leak if accord with the thickness requirement after falling spacing hole 8, open electromagnetism suction head 3 simultaneously, move sliding plate 4 to the leftmost side, make electromagnetism suction head 3 fix sliding plate 4, whole device accomplishes the preparation work this moment.
The silica gel pad to be detected can be poured on the lifting plate 1, the silica gel pad can roll on the lifting plate 1, some silica gel pads can roll into the limiting hole 8, the center of the silica gel pad is just concentric with the limiting rod 15, due to the arrangement of the limiting rod 15, even if the inner diameter of the limiting hole 8 is slightly larger than the outer diameter of the silica gel pad, the silica gel pad can be stably placed in the limiting hole 8, so that the device can detect silica gel pads with different sizes, the redundant silica gel pads can roll into the first storage box 22, the silica gel pads can be observed by naked eyes, if some silica gel pads with extremely small thickness are completely sunk into the limiting hole 8, the silica gel pads can be found out at a glance to be removed, other silica gel pads which vertically fall into the limiting hole 8 do not need attention, the first air cylinder 19 can be started after the detection is completed, the first air cylinder 19 can push the push plate 13 upwards, the push plate 13 drives the limit frame 14 to move upwards, at the moment, some vertically placed silica gel pads are not sleeved on the limit rod 15 and can be ejected by the limit frame 14, so that the silica gel pads slide to the right along with the lifting plate 1 again, the first air cylinder 19 contracts after ejection is finished, at the moment, the electromagnetic suction head 3 is opened, the scraper 7 can move to the right under the action of gravity, when some silica gel pads slightly protrude out of the lifting plate 1, the silica gel pads can be clamped with the scraper 7, at the moment, unqualified silica gel pads can be manually removed, when the scraper 7 moves to the right, the maximum thickness of the remaining silica gel pads on the surface meets the use requirement, at the moment, the second air cylinder 23 can be started, the lifting plate 1 is jacked up by the second air cylinder 23, the guide rod 9 can be in contact with the silica gel pads, the guide rod 9 enables the silica gel pads to be separated from the limit frame 14, the silica gel pads in accordance with the size can roll down to the second storage box 26 along with the guide rod 9, thereby completing the work of one size detection.
The condition of moulding plastics or extrusion is usually adopted to the silica gel pad in the course of processing, therefore if the surface of silica gel pad is not flat, general performance falls to can stick out in spacing hole 8, consequently most need detect the biggest thickness in the in-process of inspection whether satisfy the demand can.
The invention is suitable for a display screen module silica gel flatness detection tool, and the flatness of a large number of silica gel pads can be detected by the device at one time through the matching of the limiting frame 14 and the lifting plate 1 which moves up and down, and the on-off of the first air cylinder 19, the second air cylinder 23 and the electromagnetic suction head 3 only need to be controlled in the whole detection process, so that the error of manual quality detection is avoided, and the whole detection effect is improved.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
