Description

Tape printing equipment and tape printing method

Technical Field

The present invention relates to a device for packaging semiconductor products, and more particularly, to a tape-punching device and a tape-punching method for packaging semiconductor products.

Background

Referring to fig. 1, in a conventional semiconductor packaging process, a semiconductor package 10 is placed in a tray 1a after molding (stacking) operation, and a plurality of trays 1a are stacked to form a stack 1 having six trays 1a as shown in fig. 1, and the stack 1 is directly bound with a magic tape (not shown) manually and stored in a warehouse, and the magic tape is detached manually before shipment, and an operator operates a taping machine to perform taping operation in X and Y directions, that is, to configure a packaging tape (not shown) on the appearance of the stack 1.

However, in the conventional taping operation, the upper and lower trays 1a are easily separated by manually detaching the magic tape, so that the semiconductor package 10 on the tray 1a falls, thereby damaging the semiconductor package 10.

In addition, when the tape-punching operation is performed, the tape-punching position is different according to the requirement every time, and the tape-punching condition of the shipment is changed according to the requirement, so that the tape-punching error is easy to occur when the tape-punching machine is operated manually (or by an operator), and the shipment quality is reduced.

Therefore, how to overcome the various problems in the prior art has become an issue to be solved.

Fig. 2 is a schematic layout view of the taping device 2 of the present invention. This beat belting 2 includes: a placing device 21, a removing device 22, a belt-binding device 23, a conveying device 24 and a displacement device 25 (shown in detail in fig. 8).

The tape-driving device 2 is defined with a feeding area A for arranging the placing device 21, a tape-removing area B for arranging the removing device 22, a tape-driving area C for arranging the tape-driving device 23, a reflow area D for arranging the conveying device 24, and a target area E for arranging the placing device 21.

In the present embodiment, the taping device 2 has a substantially rectangular appearance, as shown in fig. 2, and the above-mentioned area can be planned according to the requirements of the process steps. For example, the feeding zone a and the target zone E may be a single space communicated with each other and located at the right side of the rectangular body, and the debanding zone B and the debanding zone C are sequentially arranged at the front side of the rectangular body and adjacent to the feeding zone a, and the refluxing zone D is located at the rear side of the rectangular body and adjacent to the target zone E. The configuration of the tape-driving device 2 and the manner of planning each region are not limited to the above.

In addition, the taping device 2 is equipped with an automation system for automatically controlling the operations of the removing device 22, the taping device 23, the conveying device 24, and the displacing device 25. For example, the automation system may be equipped with a Programmable Logic Controller (PLC) to program the coordination among the removing device 22, the belt beating device 23, the conveying device 24 and the displacement device 25. It should be understood that suitable software or firmware may be used to control the operation of the strapping device 2.

Please refer to fig. 3A and 3B, which are schematic front views of the operation process of the feeding zone and the stripping zone of the taping device of the present invention. The placing device 21 is a movable carrying seat (e.g. a push-pull trolley) for placing or carrying at least one target 9, such as a stacked set including a plurality of trays 9a (as shown in fig. 4B').

In the present embodiment, the target 9 is used for carrying a plurality of semiconductor packages (such as the semiconductor package 10 shown in fig. 1), and the target 9 is provided with an excess object 8 in the feeding area a. For example, the unnecessary object 8 is a stopper for restricting the movement of the object 9 in transport. Specifically, the redundant objects 8 are rope-shaped (such as magic tape) and fix the trays 9a with each other in a binding manner, so that the trays 9a can be prevented from scattering when the placement device 21 is manually moved (or pushed) from the outside of the taping device 2 to the feeding area a (as shown in fig. 3A) or moved from the feeding area a to the taping removing area B (as shown in fig. 3B) by using the displacement device 25 (as shown in fig. 8).

As shown in fig. 3B, the removing device 22 is disposed at the stripping zone B for receiving the target 9 (i.e. the target 9 with the redundant objects 8) from the feeding zone a and removing the redundant objects 8 from the target 9.

Please refer to fig. 4A to 4D, which are schematic top views of the operation process of the removing device of the taping apparatus of the present invention. In the present embodiment, as shown in fig. 4A, the removing device 22 includes at least one driving member 220, at least one guiding member 221, at least one stopping member 222 and at least one receiving member 223. For example, the driving member 220 is used for driving the redundant object 8 to move; the guiding member 221 is used for guiding the displacement direction of the redundant object 8; the stopping member 222 is used for stopping the guiding member 221 from guiding the redundant articles 8; the receiving member 223 is used for receiving the redundant object 8 detached from the target 9.

Specifically, the driving member 220 is located at the front and rear of the target object 9 to apply a force (e.g. a pushing force) to the redundant object 8 in the left and right directions of the target object 9. The guiding member 221 is a sheet-shaped member, which is located below the target 9 to catch or hook the redundant object 8 in the groove 90 (as shown in fig. 4B') at the bottom of the target 9 to orient the redundant object 8, and to make the guiding member 221 closer to the edges of the left and right sides of the target 9 than the redundant object 8. The stopping member 222 is a baffle plate, and is located outside at least one of the left and right sides of the object 9, so that a space S is formed between the stopping member 222 and the left and right side edges of the object 9. The receiving member 223 has a receiving space 2230 and is disposed below the space S.

In addition, at least one stopping structure 224 may be disposed as required, for example, outside the edges of the left and right sides of the target 9, so as to position the driving member 220 to stop pushing the redundant object 8.

Therefore, when the removing device 22 is activated, the guiding member 221 is moved into the groove 90 to touch the extra object 8 (as shown in fig. 4B and 4B'), then the guiding member 221 is rotated to clamp or hook the extra object 8 (as shown in the arrow direction t of fig. 4C-1) and the guiding member 221 is moved out of the groove 90 (the hook of the guiding member 221 is located in the groove 90), and the driving member 220 is used to push the extra object 8 towards the left and right sides of the target 9 (as shown in the arrow direction H of fig. 4B and 4C-1) and synchronously drive the guiding member 221 (as shown in the pushing process of fig. 4B to 4C or 4C-1 to 4C-2). Then, after the driving member 220 pushes the extra object 8 to reach the space S (as shown in fig. 4D), the stopping structure 224 stops the driving member 220, so that the driving member 220 does not push the extra object 8 any more, and the guiding member 221 passes through the space S (even under the stopping member 222, as shown in fig. 4D '), at this time, the stopping member 222 blocks the extra object 8, so that the guiding member 221 is separated from the extra object 8, and the extra object 8 falls into the accommodating space 2230 of the accommodating member 223 from the space S (as shown by the arrow G in fig. 4D'). Thereafter, the displacement device 25 moves the target 9 (from which the redundant object 8 has been removed) to the taping zone C, and the guiding member 221 returns to the original position (e.g., corresponding to the position below the groove 90) to perform the next taping operation of the target 9 with the redundant object 8.

Referring to fig. 5A to 5E and fig. 6A to 6B, the taping device 23 is configured to receive the object 9 (i.e., the object 9 from which the redundant object 8 has been removed) from the removing device 22, so as to dispose at least one packaging tape 5A,5B,6 on the object 9.

In the present embodiment, the taping device 23 includes at least one positioning assembly 230 (e.g., a block module), a first taping machine 231 (located at the first working location C1 of the taping region C as shown in fig. 2), and a second taping machine 232 (located at the second working location C2 of the taping region C as shown in fig. 2).

Specifically, the positioning assembly 230 is configured to adjust the orientation of the target 9, the first taping machine 231 is configured to arrange the packaging tapes 5A and 5B on the target 9 (as shown in fig. 5A to 5E) along a first direction X (as shown in fig. 5A to 5E), and the second taping machine 232 is configured to arrange the packaging tape 6 on the target 9 (as shown in fig. 6A to 6B) along a second direction Y (as shown in fig. 6A to 6B), wherein the first direction X and the second direction Y are perpendicular to each other.

Therefore, when the tape-driving device 23 is activated, the target 9 is first positioned at a predetermined position of the first working position C1 of the first tape-driving unit 231 by the positioning component 230, so that the target 9 presents the short-edge tape-driving orientation as shown in fig. 5A, and then the first tape-driving unit 231 performs the short-edge tape-driving operation on one side of the target 9, i.e. a packaging tape 5A is disposed along the first direction X as shown in fig. 5B to 5C. Next, the positioning assembly 230 horizontally rotates the object 9 by 180 degrees (as shown by arrow W in fig. 5C), so as to perform a short-side taping operation on the other side of the object 9, i.e. another wrapping tape 5b is disposed along the first direction X as shown in fig. 5D to 5E.

Then, the target object 9 is moved to a predetermined position (in the moving direction K shown in fig. 2) of the second working position C2 of the second taping unit 232 by the positioning component 230, the target object 9 is horizontally rotated by 90 degrees by the positioning component 230 to make the target object 9 present the long-side taping orientation shown in fig. 6A, and then the second taping unit 232 performs long-side taping on the target object 9, that is, the packaging tape 6 is disposed along the second direction Y shown in fig. 6A-6B.

It should be understood that the taping device 23 is not limited to the inclusion of multiple taping units. Specifically, by means of the positioning component 230, the orientation of the target object 9 can be adjusted, and the tape-punching device 23 can only have a single tape-punching unit as required, that is, after the tape-punching operation of the short side in the first direction X is completed, the positioning component 230 rotates the target object 9 by 90 degrees, and then the tape-punching operation of the long side in the second direction Y can be performed.

In addition, the tape-punching device 23 can arrange all the wrapping tapes 5a,5b,6 on the target 9 in different directions, or can arrange all the wrapping tapes 5a,5b on the target 9 in the same direction, so that the tape-punching directions and the number of the wrapping tapes can be arranged as required.

In addition, the tape-driving device 23 has a variety of types, and the overall structure of the tape-driving unit is well known in the art and can be designed according to the requirement, so the type of the tape-driving device 23 will not be described in detail in this embodiment.

The conveying device 24 is used for receiving the target object 9 (i.e. the target object 9 which has completed the belt-driving operation) from the belt-driving device 23, so as to move the target object 9 to the target area E. In detail, the target 9 is moved from the second belt-driving unit 232 of the belt-driving device 23 to the front end of the conveying device 24 by the displacement device 25, conveyed by the conveying device 24, and then the target 9 is moved from the rear end of the conveying device 24 to the placing device 21 of the target area E by the displacement device 25.

Referring to fig. 7A to 7C, in the present embodiment, the conveying device 24 has a variety of structures, such as a wheel rod type (e.g., a rotating shaft 70 shown in fig. 7A), a belt type (e.g., a conveying belt 71 shown in fig. 7B), a rail type (e.g., a rail 72 shown in fig. 7C, which may include a pulley 73 for carrying the object 9), or other suitable structures, and is not particularly limited.

The displacement device 25 is used for moving the object 9 into and out of different areas of the banding device 2, for example, the object 9 is moved from the placement device 21 of the feeding area a to the removal device 22, from the removal device 22 to the banding device 23, from the banding device 23 to the delivery device 24, or from the delivery device 24 to the placement device 21 of the target area E.

In the present embodiment, the displacement device 25 is at least one set of robot arms, as shown in fig. 8, but is not limited thereto.

Therefore, the whole process of the tape-driving operation of the tape-driving device 2 of the present invention is to sequentially pass through the feeding area a, the tape-removing area B, the tape-driving area C, the reflow area D and the target area E, so that the operator can obtain the desired target 9 with the packaging tapes 5a,5B,6 by pushing the placing device 21 into the feeding area a and then pushing the placing device 21 out of the target area E, thereby achieving the purpose of automatic tape-driving operation.

In addition, the tape-punching equipment 2 of the present invention can configure a plurality of sets of tape-stripping zones B and tape-punching zones C as required to simultaneously perform tape-punching operations on a plurality of sets of target objects 9.

In summary, the tape-punching apparatus 2 and the tape-punching method of the present invention stably place the target object 9 (including a plurality of trays 9a) having the redundant objects 8 (magic tapes) on the predetermined position of the tape-removing area B by the displacement device 25 by means of the design of the automated integration system, and remove the redundant objects 8 by the removal device 22, thereby preventing the trays 9a of the target object 9 from being separated from each other, and further preventing the semiconductor packages on the trays 9a from falling down to damage the semiconductor packages.

In addition, when the tape-driving device 23 performs tape-driving operation, since the tape-driving position varies according to the requirement and the tape-driving condition of the shipment changes according to the requirement, the tape-driving position and direction can be accurately controlled by the movement, positioning and rotation of the positioning component 230, so as to avoid the occurrence of tape-driving error, thereby effectively improving the shipment quality.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Modifications to the above would be obvious to those of ordinary skill in the art, but would not bring the invention so modified beyond the spirit and scope of the present invention. Therefore, the scope of the invention should be determined from the following claims.
