Description

Technical Field

[0001] The utility model relates to a device suitable for semiconductor manufacturing process, in particular to a disengagement mechanism of a strap of a tray. Background Art

[0002] With the rapid advancement of science and technology, the semiconductor industry has already played a vital role in related industries around the world, and advanced packaging technology is an indispensable part of the semiconductor industry.

[0003] In general, traditional semiconductor packaging processes place multiple sheets formed by cutting wafers into trays, usually made of polypropylene, to facilitate transporting the sheets in the production line. In order to transport more sheets simultaneously in the production line, the trays are stacked to form a tray stacking group. In order to prevent the trays from slipping or detaching from each other during subsequent transportation, a strap is usually used to secure the trays in the tray stacking group. Before entering the next process, the strap must be removed to remove the sheets from the trays.

[0004] However, the previous method of manually removing the belt is inevitably prone to human errors, and may also cause disadvantages such as manpower consumption and cumbersome operations. Figure 1 A tape stripping device suitable for semiconductor manufacturing process is disclosed. Figure 1 The stripping device includes a removal device 9 for removing two straps 8, and the removal device 9 includes a plurality of driving members 91 spaced apart from each other for pushing the straps 8, a plurality of stop members 92 respectively arranged corresponding to the driving members 91, and two receiving members 93 respectively defining two accommodating spaces 94 and resting on the stop members 92. When in use, the removal device 9 is operated by an automated robotic arm, and the driving member 91 is used to push the straps 8 bundled in a tray stacking group toward the left and right sides. When the straps 8 are pushed to the upper area of the receiving member 93, the stop member 92 will stop the driving member 91 from moving, and thereby stop pushing the straps 8. At this time, the straps 8 are detached from the tray stacking group and fall into the accommodating space 94 of the receiving member 93, completing the process of detaching the straps 8.

[0005] However, in the process of removing the belt 8 from the pallet stacking group, the above-mentioned belt removal equipment may cause displacement between the pallets in the pallet stacking group due to factors such as uneven force or unclear positioning, or uneven stacking, which may cause chaos in the subsequent production line. Therefore, the previous equipment needs to be improved. Utility Model Content

[0015] The tray strap detachment mechanism of the present invention further comprises two positioning identification units spaced apart from each other along the second direction and arranged above the bottom plate, and used for detecting whether the strap has detached from the tray stacking group.

[0028] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0029] See Figure 2 The embodiment of the detachment mechanism of the tray strap of the utility model is suitable for bundling two mutually spaced straps 8 in a tray stacking group 81 formed by stacking multiple trays 80, and subsequently performing the detachment and recovery operations of the straps 8.

[0030] A first direction X and a second direction Y perpendicular to the first direction X are defined. The following operations of this embodiment are generally described by moving along the first direction X or the second direction Y.

[0031] See Figure 2 and Figure 3 , an embodiment of the disengagement mechanism of the strap of the pallet of the present invention, this embodiment includes a base plate 1 suitable for setting the pallet stacking group 81, two fixing jigs 2 arranged on the base plate 1 and spaced apart from each other along the first direction X to press against the pallet stacking group 81, two detection parts A arranged on the base plate 1 at intervals along the first direction X, two pressing modules 3 arranged on the base plate 1 at intervals along the first direction X, two stripping modules 4 extending in a direction parallel to the second direction Y and spaced apart from each other along the first direction X on the base plate 1, two recovery units 5 spaced apart from each other along the second direction Y and respectively arranged on opposite sides of the pallet stacking group 81, two positioning judgment units 6 spaced apart from each other along the second direction Y above the base plate 1, and a visual inspection module 7 arranged above the base plate 1 and used to photograph the pallet stacking group 81 from a height higher than the pallet stacking group 81. The detection elements A preferably adopt an optical sensing mechanism and cooperate with each other to form a sensing line A0 along the first direction X and suitable for penetrating the tray stacking group 81 to determine whether the tray stacking group 81 is fixed to the fixing fixture 2.

[0032] See Figure 3In order to facilitate the description of the operation of the pressing module 3 and the stripping module 4, Figure 3 The visual inspection module 7 is not shown in the figure. Each of the pressing modules 3 includes a pressing plate 31 that can be flush against the tray stacking group 81 along the second direction Y. Each of the pressing plates 31 has a plate 311 that can be flush against the tray stacking group 81 along the second direction Y, and two connecting members 312 extending along the first direction X and connected to both sides of the plate 311 at intervals along the second direction Y, and used to balance the force of the plate 311 when pressing. Specifically, the pallets 80 in this embodiment can be stacked in 3 to 13 layers, so the longitudinal height of each plate 311 of each pressing plate 31 must be at least higher than the longitudinal height of 13 layers of the pallets 80.

[0033] See Figure 2 、 4 to Figure 6 Each of the stripping modules 4 includes a driving member 41 spaced apart from the corresponding pressing module 3, and two stripping members 42 spaced apart from each other and connected to the driving member 41 along the second direction Y. The stripping members 42 can move between a standby position and a stripping position along the second direction Y. Figure 2 As shown, it is the state in the standby position, and as Figure 4 and Figure 5 As shown, when the stripping member 42 of each stripping module 4 is in the stripping position, each driving member 41 drives the plate 311 to press against the tray stacking group 81, and can drive the stripping member 42 to push the belt 8 away from each other in the second direction Y until the belt 8 is completely detached from the tray stacking group 81 and falls into the recovery unit 5.

[0034] It is worth mentioning that the drive member 41 of the stripping module 4 is driven by a pneumatic cylinder in this embodiment to move the stripping member 42. However, in actual implementation, the stripping member 42 can also be driven by a motor, and the driving method is not limited to the above example. In addition, in addition to driving the stripping member 42, the drive member 41 can also use air pressure to adjust and drive the plate 311 of the pressing plate 31 to press against the tray stack 81. In response to different types of tray stacks 81 or different numbers of trays 80, the pressure can be changed by adjusting the air pressure to achieve the optimal fixing effect.

[0035] Also, see Figure 6Each of the recovery units 5 is used to recover the straps 8 that have been detached from the tray stacking group 81, and includes a recovery component 51 that defines a recovery space 50, and at least one set of full-stack sensors 52 disposed in the recovery space 50. Each of the recovery components 51 is specifically a strap storage box, and the full-stack sensor 52 preferably adopts an optical sensing mechanism to detect whether the strap 8 exceeds the capacity of the recovery space 50. It is also particularly noted that, in this embodiment, according to on-site requirements, the full-stack sensors 52 of each of the recovery units 5 are preferably multiple, and are arranged equidistantly and horizontally spaced from each other along the first direction X, and form a grating-like pattern to detect the possibility that the strap 8 falls into the recovery space 50 and may cause irregular stacking.

[0036] Re-read Figure 3 Each positioning and determination unit 6 includes two positioning and determination elements 61 spaced apart from each other along the first direction X. The positioning and determination elements 61 are defined as projected along the first direction X, thereby forming a virtual sensing line 60 at the opening of the recycling unit 5 on the same side. The virtual sensing line 60 utilizes infrared light projection and can detect whether the strap 8 has successfully fallen from the tray stack 81.

[0037] In practice, when the stripping module 4 begins to operate, the positioning determination element 61 of the positioning determination unit 6 is composed of a photoelectric sensor and projects infrared light through the virtual sensing line 60. Therefore, when the strap 8 is driven to the virtual sensing line 60, it will block the virtual sensing line 60 and then automatically fall into the recovery space 50 of the recovery element 51 due to gravity. At this time, the infrared light is no longer blocked. Therefore, the presence or absence of the blocking signal on the virtual sensing line 60 can be used to determine whether the strap 8 has been successfully dropped.

[0038] Re-read Figure 2 It should be noted that the visual inspection module 7 in this embodiment mainly uses a CCD visual inspection system to assist in inspection. When the tray stacking group 81 is placed on the bottom plate 1 and fixedly pressed against the fixing fixture 2, the visual inspection module 7 can read the barcode according to the important information recorded on the barcode above the tray stacking group 81. In addition, when the tray stacking group 81 is fixedly pressed against the fixing fixture 2, the visual inspection module 7 can also be used to confirm whether the tray stacking group 81 is completely placed on the bottom plate 1, and at the same time confirm whether the tray stacking group 81 is tied with the strap 8. In addition, by further cooperating with the positioning identification member 61, it can also be confirmed whether the strap 8 has been successfully detached, thereby serving as a mechanism to ensure whether this embodiment is operating normally.
