Description

Bundling mechanism for strapping Tray disc fixing strap

The present invention relates to the field of transport of Tray discs, and more particularly to a disassembly mechanism dedicated to the removal of strapping Tray disc retaining straps.

Most of the Tray discs used in high-tech semiconductor products, also known as "semiconductor trays". In order to meet the requirements of conduction or non-conduction, the Tray discs are stacked together, and the series of manufacturing processes such as degaussing and high-temperature drying are performed, and the end of the Tray disc is bundled and transported by an end tape such as disclosed in Taiwan Patent No. 591072. To the destination.

During the production process, in order to prevent the stacked Tray discs from being scattered all over the place, a set of Tray discs which are bundled and folded as shown in the patents such as Taiwan No. M516566 and No. M516575 are usually used. The fixing has a head end and a tail end, and a devil felt is sewn at a side end of the fixing belt adjacent to the head end, and a tail end of the fixing belt is connected to a ring body.

In use, the fixing strap is at the bottom end of the stacked Tray disc, and the head end passes through the ring body, and after the belt body is folded in half, the side of the fixing belt is adhered with the devil felt, and the stacked Tray disc has a temporary restraining effect.

However, the process of removing the strap from the Tray disc is not as easy or smooth as imagined. The Tray disk forms two pairs of grooves at the bottom like the patents of Taiwan No. M269283 and No. M269284. Each groove is just in the way of the outward movement of the fixing band, and becomes a stumbling block that the fixing tape cannot be removed. Since the fixing tape is easily caught in the groove, the fixing band is blocked by the side wall of the groove, and the working time of the unloading is relatively delayed.

Therefore, how to smoothly remove the fixing tape from the stacked Tray disk has become an urgent problem to be solved by the present invention.

In view of this, the present invention provides a detaching mechanism for binding a Tray disk fixing tape, the main purpose of which is to adopt a structure similar to the filling, so that the groove temporarily disappears at the initial stage of disassembly, and the fixing tape is smoothly removed from the Tray disk, effectively solving the problem. The grooves hinder the disassembly and shorten the working time required for the removal.

For the above object, the detaching mechanism of the present invention is used to remove the fixing strap of the bundled Tray disc. The detaching mechanism comprises: a filling member; a movable seat for pivoting the filling member to the movable seat and maintaining the ascending state; a bottom plate connected to the movable seat, allowing the movable seat and the filling member to move back and forth relative to the bottom plate; a claw; a pusher fixed to the bottom plate, the pusher being coupled to the claw to drive the pawl to move back and forth in the retracted and extended positions; and a one-way valve engaging a mouth, the check valve being fastened to the bottom plate and supporting the mouth The high pressure fluid is ejected toward the jaws.

When the two disassembly mechanisms are disposed on a machine table, the bottom plate reciprocates on the side of the Tray disk stacked on the machine table, and the restriction padding is added to the groove of the lowermost Tray disk.

In the retracted position, the pusher operating pawl does not contact the strap of the bundled Tray disc. In the extended position, the pusher drives the jaws to grip the strap.

During the disassembly, the bottom plate and the claw clamping fixing belt are displaced outward, and the filling member is inserted into the fixing belt to be displaced in the same direction, and the fixing belt is expanded by the filling member, and the Tray is removed from the groove. The disc, the high-pressure fluid sprayed from the mouth prevents the claws from hooking up the removed strap.

Wherein, the machine is equipped with a transmission assembly and a terminator. The drive assembly arranges for the bottom plate to reciprocate on the side of the stacked Tray disk, the terminator limiting the fill member to be added to the recess of the lowermost Tray disk. During disassembly, the bottom plate is driven by the drive assembly, and the associated jaw clamping retaining strap is displaced outwardly so that the mating member can be inserted into the retaining strap to move in the same direction. The strap is expanded by the filler member, over the recess and out of the Tray disc.

Thus, the present invention removes the detaching mechanism of the bundled Tray disk fixing tape, and the filling member temporarily dissipates the groove at the initial stage of disassembly, thereby helping the fixing tape to be smoothly removed from the Tray disk, thereby effectively solving the obstacle caused by the groove to be disassembled, and simultaneously Reduce the time required for unloading.

The above-mentioned objects, structures and features of the present invention will be described in detail with reference to the preferred embodiments of the present invention. .

Figure 13 is an action diagram of the Tray disc and the detaching mechanism at the later stage of disassembly.

Referring to Fig. 1, a specific structure of a detaching mechanism 10 is illustrated. A filling member 20, a claw 30 and a check valve 40 are mounted on a bottom plate 12. The main characters of the detaching mechanism 10 are the filling member 20 and the claws 30, and the filling member 20 is replenished to the groove, so that the groove temporarily disappears at the initial stage of disassembly, and the fixing belt is clamped by the claw 30, and smoothly moves away from the stack. Tray disk. For the disassembly of the fixing tape, the filling member 20 effectively solves the obstruction of the groove while shortening the working time required for the claw 30 to remove the fixing tape.

The check valve 40 is a supporting angle of the detaching mechanism 10. At the end of disassembly, the one-way valve 40 ensures that the strap is removed from the jaws 30. Therefore, the check valve 40 is separated from the bottom plate 12 and is no longer actuated in synchronization with the filler member 20 and/or the pawl 30, and is within the permissible range of the present invention. In other words, the one-way valve 40 is attached to the filler member 20 and the pawl 30 mounted to the bottom plate 12. Therefore, the check valve 40 and the bottom plate 12 can be disposed in different orientations of a machine table 50 (see FIG. 4), which are not necessary for simultaneous operation. The check valve 40 can perform a certain action alone without interfering with the filling member 20 or the claws 30.

As shown in Figs. 1 to 3, the bottom plate 12 and the filling member 20 are coupled together via a movable seat 25. A straight rail slide 13 fixed under the movable seat 25 can be spanned on a straight rail 11 secured to the bottom plate 12 to slide the movable seat 25 back and forth along the length of the straight rail 11.

An elastic member 26 connects the movable seat 25 and the bottom plate 12, so that the movable seat 25 is retracted (or close to) the bottom plate 12 as a normal state. In this embodiment, the elastic member 26 is a tension spring, and the two ends of the tension spring are connected to the bottom plate 12 and the movable seat 25 by a set of fasteners 27 such as screws and bolts, and the movable seat 25 is required to move relative to the bottom plate 12. Force.

In addition, the upright portion 28 is integrally formed with the movable seat 25 on a different side from the contact member 29 that is locked to the movable seat 25. The upright portion 28 is erected on the top surface of the movable seat 25, and is different from a pole 24 protruding from the bottom surface of the movable seat 25.

In the present embodiment, the filling member 20 has a lateral portion 21 and a hole 22. Using bump In the fitting manner, the filling member 20 is pivotally connected to the side of the upright portion 28 through the hole 22. The transverse portion 21 is located above the upright portion 28 for shielding another elastic member 23 mounted on the upright portion 28, and under the force of the elastic member 23, provides the torque required for the filling member 20 to rise relative to the upright portion 28. The transverse portion 21 is blocked from the top surface of the upright portion 28, and the angle at which the filler member 20 is raised relative to the upright portion 28 does not exceed 50°.

In this embodiment, the elastic member 23 is a torsion spring, and the torsion spring has a spiral ring and two legs. The spiral ring is pivotally connected to the other side of the upright portion 28, one of the two legs abuts the upright portion 28, and the other foot is placed on the other side. The transverse portion 21 generates a certain torque or force. In some embodiments, the resilient member 23 can be a compression spring or a reed that also provides the force required to lift the filler member 20.

The back side of the claw 30 is coupled to an auxiliary plate 31 to connect the auxiliary plate 31 to a pusher 32. In the present embodiment, the front side of the pawl 30 is flat. In some embodiments, the front side of the jaw 30 is rugged, such as a plurality of rows of ratchets.

The pusher 32 may be a pneumatic (or hydraulic) cylinder that is fastened to a main plate 33 that is locked to the base plate 12. The pneumatic cylinder has a telescopic shaft (not shown) for coupling the auxiliary plate 31 to drive the pawl 30 to move back and forth in a retracted position and an extended position along a direction substantially perpendicular to the straight rail 11.

A lower stage seat 34 is secured to the other side of the main board 33, and a resist 35 is coupled to the lower stage seat 34. The resisting member 35 may be a pneumatic (or hydraulic) cylinder, and an external thread is arranged on the cylinder body for locking into the internal threaded hole of the low-step seat 34, and the pneumatic cylinder is not interfered with and the claw 30 is moved back and forth in the retracted and extended positions. . Of course, the pneumatic cylinder also has a shaft 36 that is telescopic.

The one-way valve 40 engages a nozzle 41 and a tubular body 42. When the check valve 40 is fastened to the sub-plate 43 locked to the bottom plate 12, the nozzle 41 is supported by the check valve 40 toward the bottom or the bottom of the claw 30, and the high-pressure fluid of the discharge pipe body 42 is introduced into the check valve 40. Such as gas.

As shown in FIGS. 4 and 5, a machine table 50 is provided with a pair of brackets 52, two track sets 53 and a transmission assembly 54 on a flat support surface 51. In groups of two, each group of disassembly mechanisms 10 is fixed to the machine The support surface 51 of the table 50 is located on both sides of the bracket 52.

In the figure, the brackets 52 are spaced apart from the support surface 51 for holding up the stacked Tray disc 60 such that the recess 61 of the bottommost tray disc 60 and the support surface 51 are maintained at a certain height, and in each bracket 52. The terminator 55 is oppositely fixed in the opposite direction. In the present embodiment, the terminator 55 is a pneumatic (or hydraulic) cylinder capable of increasing or decreasing the total length. In some embodiments, the terminator 55 can be a rod, rod or block of constant length.

Structurally, the track set 53 is substantially identical to the aforementioned straight track and straight track slides, with the difference being a different number. That is to say, each track group 53 has two straight rails, which are composed of two sliding seats fixed to the bottom plate 12. Secondly, the straight rails and the brackets 52 are parallel to each other, and the detaching mechanism 10 is guided through the carriage to reciprocate outside the bracket 52.

The transmission assembly 54 has two screws 56 which are mounted on the outside of the track set 53 and which are parallel to the bracket 52 and can be driven by a pulley set or other transmission mechanism. The two linkages 57 are a group, and each of the linkages 57 is screwed to the screw 56 to be connected to the bottom plate 12. When the screw 56 drives the interlocking seat 57, the detaching mechanism 10 drives the detaching mechanism 10 to move in the same direction.

A pressing member 64 is designed on the upper surface of the machine table 50, and can be lowered onto the uppermost Tray disk 60 in response to operational requirements, and the pressing force is applied to prevent the stacked Tray disk 60 from moving. Therefore, the press member 64 has a positioning function for the Tray disc 60.

It is not difficult to understand in Figures 6 and 7 that during the preparation for disassembly, the terminator 55 abuts against the pole 24, counteracting (or offsetting) the force exerted by the elastic member 26 on the movable seat 25, except that the touch member 29 is kept away from the resistance. In addition to the member 35, the padding member 20 is just below the stacked Tray disk 60, thereby being replenished into the recess 61 of the lowermost Tray disk 60. Due to the lifting action of the filling member 20, the highest end of the lateral portion 21 touches the wall surface of the recess 61.

As shown in Fig. 8, the pusher 32 is in an unactuated state during preparation for disassembly. At this point, the pawl 30 stays in the retracted position but does not approach the strap 62 that is tied to the Tray disc 60.

In Fig. 9, each of the detaching mechanisms 10 is brought into the starting phase, and the driving jaws 30 are brought from the retracted position to the extended position, and the fixing belt 62 is clamped from both sides of the Tray disc 60. When the transmission assembly 54 drives the detaching mechanism 10 to the end of the screw 56 (see Fig. 4), the claws 30 are displaced outwardly (i.e., in the short side direction) along the long side of the Tray disk 60 with the fixing band 62 interposed therebetween.

At the same time, under the condition that the upright 24 abuts the terminator 55, the movable seat 25 is pulled by the elastic member 26 toward the bottom plate 12, and the filling member 20 remains in the groove 61 except that the total length of the tension spring is continuously reduced (see Fig. 7) is not affected by the shortening of the distance between the bottom plate 12 and the movable seat 25 (i.e., the bottom plate 12 is close to the movable seat 25).

In Fig. 10, the claws 30 are continuously displaced outward along the long sides of the Tray disc 60, and the straps 62 are passed through the recesses 61 (see Fig. 7). The filling member 20 is inserted into the fixing belt 62 as shown in Figs. 7 and 11 to prevent the fixing belt 62 from sinking into the recess 61. At this point, the bottom plate 12 continues to approach the movable seat 25 with the associated shaft 36 against the contact member 29 such that the overall length of the resilient member 26 is no longer changed.

As shown in Fig. 12, the bottom plate 12 and the movable base 25 are displaced in the same direction as the fixed belt 62 under the condition that the shaft 36 is placed against the contact member 29. Since the side of the groove 61 is inclined, the lateral portion 21 is pressed by the bottom surface of the lowermost layer tray 60 to approach the horizontal state. The fixing band 62 is expanded by the filling member 20 and smoothly passes over the groove 61.

As shown in Fig. 13, when the fixing strap 62 moves away from the Tray disc 60 with the claw 30, the bottom plate 12 is parked on the rail group 53, the shaft 36 of the resisting member 35 is increased in length, and the pushing member 29 is pushed in the direction of the arrow 80. Moving on, the movable seat 25 is displaced by a certain distance from the bottom plate 12, so that the filling member 20 moves in the same direction to prevent the fixing belt 62 from being caught by the filling member 20.

At the end of disassembly, the pusher 32 urges the pawl 30 from the extended position back to the retracted position, and the pawl 30 moves in the direction of arrow 82 of Fig. 13 and no longer maintains contact with the strap 62. Therefore, the fixing belt 62 is dropped by gravity and can be recycled and reused.

If necessary, the nozzle 41 directs a high pressure fluid (such as air) along the arrow 84 of Figure 13 The direction is sprayed toward the lower half of the pawl 30 or the strap 62 to prevent the teeth of the pawl 30 from hooking the burrs or braided portions of the strap 62.

Of course, the detaching mechanism 10 is brought back to the original position by the transmission assembly 54, waiting for the execution of the next disassembly operation.
