Description

Technical Field

[0001] This invention relates to the field of packaging equipment for reel packaging trays, and more particularly to an automatic tape applicator for reel packaging trays. Background Technology

[0002] In the semiconductor industry, tape and reel (reel, roll, spool, roll) are the main packaging materials for ICs and are important products for IC storage, transportation and back-end material supply. Tape and reel, also known as IC tape and reel, is a type of tape that can hold multiple electronic components on a single tape and then coil the tape onto a reel.

[0003] Currently, after integrated circuit chips are packaged into rolls, they usually need to be wrapped with protective tape and the joints of the protective tape are sealed. After the disc-shaped chips have undergone manual spot checks, a protective tape of a certain length is manually taken, wrapped around the disc once, and tape is pasted at the joints of the protective tape. The protective tape can better protect the chips and prevent chip damage. In addition, the protective tape can also prevent chip damage that may occur during transportation.

[0004] Currently, there are two main methods for applying tape. One method involves cutting the tape to the required length first and then applying it using a suction device. The other method involves cutting the tape after application. The first method is more complex, as the tape cannot be fed simply by unwinding. The second method is less suitable for reel packaging trays, as the cutter may interfere with the reel packaging tray and could potentially damage the chips on the tape. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic tape applicator for reel packaging trays. The tape is cut, and with the adsorption holes on the applicator head, the tape can be pulled off from the cut by rotating the reel packaging tray. At the same time, the tape can be continuously fed, achieving continuous and automatic tape application.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: an automatic tape applicator for reel packaging trays, comprising an applicator mounting base, an applicator movable base mounted on the applicator mounting base via an applicator movable device, a tape roll placed on the applicator movable base, the tape roll passing sequentially through a take-up and untake-up drum, a cutting device and an applicator head on the applicator movable base, the take-up and untake-up drum being equipped with a take-up and untake-up motor, the applicator head having an applicator adsorption hole, the applicator adsorption hole being equipped with a negative pressure adsorption component, and the cutting device being used for a center cut of the tape.

[0007] This solution uses a cutting device to create an opening in the tape, which does not affect the pulling and unwinding of the tape. After the tape is applied, the tape will be attracted to the adhesive adsorption hole on the applicator head. At this time, the cut is located between the reel packaging tray and the applicator head. Thus, the tape can be broken simply by separating the applicator head from the reel packaging tray. The structure is simple, and the position of the cutting device will not interfere with the reel packaging tray at all.

[0008] Preferably, the cutting device includes a cutting cylinder mounted on the adhesive application seat, the cutting cylinder being connected to a cutting blade, the cutting blade being a conical block with a cone tip at the end near the adhesive tape.

[0009] This preferred solution defines the structure of the cutting device. Through the conical design of the cutting blade, the size of the cut can be controlled by controlling the extension and retraction length of the cutting cylinder, thus adapting to tape cutting of various widths.

[0010] Preferably, the adhesive applicator has a row of horizontal adhesive adsorption holes, and the center of the adhesive adsorption holes is at the same height as the center of the cutting blade.

[0011] This preferred solution ensures that the center height of the adhesive adsorption hole is consistent with that of the cutting blade. In this way, when the tape is broken, the position corresponding to the adhesive adsorption hole is the cutting part, and there will be no misalignment between the cutting part and the adsorption hole, which would cause the adhesive adsorption hole to have an adsorption force on the tape to be broken. This improves the neatness of the tape after it is broken.

[0012] Preferably, a tail-folding device is provided between the cutting device and the adhesive applicator. The tail-folding device includes a tail-folding opening between the cutting device and the adhesive applicator. A tail-folding air column is provided on the outside of the tail-folding opening. An air blowing hole is provided on the tail-folding air column for blowing the tape into the tail-folding opening. The air blowing hole cooperates with the air blowing component. A tail-folding component is provided inside the tail-folding opening to make the tape portions blown in stick together.

[0013] This preferred solution includes a folding device, which uses a folding air jet to blow the tape into the folding opening in a concave shape. This facilitates the folding assembly to adhere the concave portions of the tape to each other and fold the tape. When the folded tape is attached to the protective tape on the reel packaging tray, the efficiency of finding the tape end and removing the protective tape is high.

[0014] Preferably, the tail-folding assembly includes a tail-folding rotating block mounted via a vertically oriented tail-folding rotating shaft. The tail-folding rotating block includes a tail-folding block body for adhering the tape portions to each other and a connecting block body for connection. The connecting block body is hinged to a tail-folding connecting block, and the other end of the tail-folding connecting block is hinged to a tail-folding driving block, which is driven by a tail-folding cylinder.

[0015] This preferred solution uses a cylinder to drive the tail-folding block to rotate, thereby pressing the concave tape portion blown into the tail-folding opening onto the tail-folding block, thus achieving mutual adhesion of the concave tape portions. The tail-folding part, in conjunction with the tail-folding air-blowing column structure, can achieve tail-folding through simple operation.

[0016] Preferably, the adhesive applicator is provided with a groove-shaped film feeding slant, the tape roll is placed on the film feeding slant and the adhesive applicator, and the adhesive applicator is also provided with an active seat cover plate for limiting the upper part of the tape roll, and the film feeding slant and the adhesive applicator are provided with film roll limiting posts for limiting the position of the tape roll.

[0017] This preferred solution uses a film unloading slant frame in conjunction with an adhesive applicator to place the tape roll. Compared with the existing rotary drum structure, it has a simpler structure and is easier to pick up and put down. When unloading, the tape roll will also be moved along with it due to the reduction in thickness, and it will always be limited by the film roll limiting post, so it will not fall off.

[0018] Preferably, the adhesive application device includes an adhesive application motor and an adhesive application gear on the adhesive application mounting base. The adhesive application motor drives the adhesive application gear to rotate through a transmission structure. The adhesive application mounting base and the adhesive application seat are connected by a slider and a slide rail structure. The adhesive application seat is provided with an adhesive application rack that meshes with the adhesive application gear.

[0019] This preferred solution uses a combination of a toothed column and a rack to move the adhesive applicator. This allows the movement distance of the adhesive applicator to be controlled by the number of rotations of the adhesive applicator motor, preventing excessive movement from damaging the chips on the reel packaging tray.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0027] like Figure 1 and Figure 3-5 As shown, the specific structure of the present invention is as follows: an automatic tape applicator for reel packaging trays, including a tape applicator mounting base 51, a tape applicator movable base 54 mounted on the tape applicator mounting base 51 via a tape applicator movable device, a tape roll 57 placed on the tape applicator movable base 54, the tape 67 of the tape roll 57 passing sequentially through a take-up and untake-up spool 60, a cutting device 63, and a tape applicator head 65 on the tape applicator movable base 54, the take-up and untake-up spool 60 being equipped with a take-up and untake-up motor 59, and the tape applicator head 65 having a tape applicator opening. The adhesive adsorption hole 66 is equipped with a negative pressure adsorption component. The cutting device 63 is used for the center cut of the adhesive tape 67. The cutting device 63 includes a cutting cylinder 77 set on the adhesive application seat 54. The cutting cylinder 77 is connected to a cutting knife 78. The cutting knife 78 is a conical block with a cone tip at the end near the adhesive tape 67. A row of horizontal adhesive adsorption holes 66 is opened on the adhesive application head 65, and the center of the adhesive adsorption hole 66 is at the same height as the center of the cutting knife 78.

[0028] The specific tape application operation of the tape application mechanism of the present invention is as follows. It needs to be used in conjunction with a rotatable reel packaging tray. At the beginning, the tape roll (specifically masking tape) 57 needs to be placed first. Then, the tape 67 is pulled out from the end of the tape roll 57, and the tape passes through the take-up and untake-down roll 60, the cutting device 63 and the tape application head 65 in sequence. The tape 67 is then suctioned by negative pressure through the tape application suction hole 66, thus completing the preparation work for tape application. Afterwards, the cutting cylinder 77 drives the cutting blade 78 to move towards the tape, so that its conical tip opens at the center of the tape 67. Then, the tape application moving device drives the tape application moving seat 54 and its upper tape application part to move as a whole, so that the tape application head 65... 5. Press the tape 67 onto the protective strip of the reel packaging tray. At the same time, the take-up and unwind motor 59 drives the take-up and unwind drum 60 to rotate, unwinding the tape roll 57. Then, the reel packaging tray rotates to complete the tape application and seal the protective strip. Afterward, the tape adsorption hole 66 is subjected to negative pressure adsorption again. At this time, the cut tape part will be at the outermost tape adsorption hole 66. Then, the tape application device is returned to its original position, and the tape 67 can be pulled off from the cut. Then, the take-up and unwind motor 59 drives the take-up and unwind drum 60 to perform a winding operation, so that the tape 67 between the tape application head 65 and the take-up and unwind drum 60 is taut. The subsequent cutting and tape application operations can then be performed again.

[0029] like Figure 1 and Figure 3-4 As shown, a tail-folding device 64 is provided between the cutting device 63 and the adhesive applicator 65. The tail-folding device 64 includes a tail-folding opening between the cutting device 63 and the adhesive applicator 65. A tail-folding air-blowing column 62 is provided on the outside of the tail-folding opening. The tail-folding air-blowing column 62 has an air-blowing hole for blowing the tape 67 into the tail-folding opening. The air-blowing hole cooperates with the air-blowing component. A tail-folding component is provided inside the tail-folding opening to achieve mutual adhesion of the tape portions blown in. The tail-folding component includes a tail-folding rotating block 72 installed through a vertically oriented tail-folding rotating shaft 71. The tail-folding rotating block 72 includes a tail-folding block body for mutual adhesion of the tape portions and a connecting block body for connection. The connecting block body is hinged to a tail-folding connecting block 74. The other end of the tail-folding connecting block 74 is hinged to a tail-folding driving block. The tail-folding driving block is driven by a tail-folding cylinder 73.

[0030] To facilitate tearing the tape 67 during subsequent use, this application includes a tail-folding device. The specific tail-folding operation is as follows: after completing the tape application preparation work and before cutting the tape, the take-up / unwind motor 59 drives the take-up / unwind drum 60 to unwind, thus slackening the tape between the application head 65 and the take-up / unwind drum 60. Then, the air blowing assembly operates, causing air to blow through the air holes on the tail-folding air column 62, blowing the tape 67 into the tail-fold opening. The blown portion forms a concave shape. Then... The folding cylinder 73 drives the folding drive block to move, and then the folding connecting block 74 transmits the folding rotating block 72 to rotate around the folding shaft 71. This allows the folding block to press the concave tape inside the folding opening, so that the concave tape parts stick together. Then, the take-up and untake-down drum 60 is used to wind up the tape, straightening the folded tape 67. Then, the cutting and tape application operations are performed. After folding, the sticking tape parts can be found and quickly torn off when used later.

[0031] like Figure 1-3 As shown, the adhesive applicator 54 is provided with a groove-shaped film feeding slant 56, and the tape roll 57 is placed on the film feeding slant 56 and the adhesive applicator 54. The adhesive applicator 54 is also provided with an active seat cover plate 58 for limiting the upper part of the tape roll 57, and the film feeding slant 56 and the adhesive applicator 54 are provided with film limiting posts 61 for limiting the position of the tape roll 57.

[0032] Traditionally, tape rolls are unloaded by placing them on a rotating tray. However, this application uses an adhesive-applying movable seat 54 and a tape roll unloading inclined frame 56 to form two unloading support points at a certain angle. The tape roll 57 is placed on the adhesive-applying movable seat 54 and the tape roll unloading inclined frame 56, and the tape roll 57 is made to adhere to the two tape roll limiting posts 61. During subsequent unloading, the tape roll 57 is pulled along with the unloading process, always adhering to the two tape roll limiting posts 61 to prevent it from falling off. Compared with existing tape roll placement structures, it is simpler to pick up and put down, has a simpler structure, and will not interfere with other structures.

[0033] like Figure 1-2 As shown, the adhesive application device includes an adhesive application motor 52 and an adhesive application gear 53 mounted on an adhesive application mounting base 51. The adhesive application motor 52 drives the adhesive application gear 53 to rotate through a transmission structure. The adhesive application mounting base 51 and the adhesive application seat 54 are connected by a slider and a slide rail structure. The adhesive application seat 54 is provided with an adhesive application rack 55 that meshes with the adhesive application gear 53.

[0034] Since the tape is applied to reel packaging trays, the tape application head 65 requires high precision. First, the required movement distance of the tape application head 65 needs to be determined based on the placement position of the reel packaging tray. Then, the required number of rotations (radians) of the tape application motor 52 is calculated. The tape application motor 52 can then be rotated the set number of times, which drives the tape application motor 53 to rotate through the transmission structure. In turn, the meshing of the teeth drives the tape application motor rack 55 to move, thus allowing the tape application seat 54 to move precisely along the slider and slide rail structure.
