Description

Technical Field

[0001] This invention relates to the field of packaging equipment for reel packaging trays, and more particularly to a rotating clamping mechanism for packaging reel packaging trays with protective tape. 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] To improve the packaging efficiency of reel trays, mechanical mechanisms are used to replace manual wrapping of protective tape. This requires a rotating turntable to support the reel tray, along with a corresponding structure to press the protective tape onto the reel tray and rotate it synchronously or relative to it. The clamping or loosening state also needs to be adjustable. Most existing technologies separate the reel tray rotation from the clamping structure, using a set track to make the clamping structure rotate around the reel tray. Furthermore, the clamping structure needs to be equipped with a mechanism to adjust the clamping or loosening state of the clamping components. This structure is complex and prone to interference with other structures. During installation, the coaxiality requirements between the track and the reel tray rotation structure are high, which can easily lead to installation errors that cause the clamping structure to damage the chip. Summary of the Invention

[0005] The purpose of this invention is to provide a rotating clamping mechanism for protective packaging of reel packaging trays. The clamping component is rotated by a rotating swing arm, and the rotating center structure of the swing arm is sleeved on the rotating shaft of the reel packaging tray. The rotation of the swing arm and the rotation of the reel packaging tray have good coaxiality. Compared with the structure of an external track, the structure is also simpler.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a rotating clamping mechanism for packaging protective tape on reel packaging trays, comprising a rotating base, a rotating shaft connected to the rotating base via a rotating motor, a turntable for carrying reel packaging trays mounted on the rotating shaft, a sleeve shaft that can rotate relative to each other fitted on the rotating shaft, a swing arm drive structure fitted on the sleeve shaft, a swing arm fixedly fitted on the sleeve shaft, the swing arm being located below the turntable, and the outer end of the swing arm extending beyond the reel packaging tray on the turntable, a clamping device provided on the outer end of the swing arm that cooperates with the reel packaging tray on the turntable, the clamping device being used to press the protective tape inside the reel packaging tray.

[0007] In this design, the swing arm rotation center structure is sleeved on the rotating shaft of the reel packaging tray. The rotation of the swing arm and the rotation of the reel packaging tray have good coaxiality. The rotation of the clamping device is realized through the swing arm. Compared with the existing track-type structure, the structure is simple and has smaller error.

[0008] Preferably, the swing arm drive structure includes a swing arm transmission pulley fixedly sleeved on a bushing and a swing arm motor mounted on a rotating seat. A swing arm output pulley is sleeved on the output shaft of the swing arm motor, and the swing arm output pulley and the swing arm transmission pulley are connected by a swing arm transmission belt.

[0009] Preferably, both the swing arm motor and the rotary motor rotate at a fixed speed after starting, and the rotational shaft and the sleeve shaft rotate at the same speed.

[0010] This preferred solution fixes the rotation speed of the swing arm motor and the rotating motor. This ensures that the shaft and bushing rotate synchronously by means of the transmission ratio and the rotation speed of the swing arm motor and the rotating motor. This ensures that the clamping point will not move relative to the reel packaging tray when the reel packaging tray is clamped by the clamping structure.

[0011] Preferably, the clamping device includes a clamping shaft mounted on a swing arm via a bearing seat and parallel to the rotating shaft. A clamping block is mounted on the clamping shaft and rotates with it. The lower part of the clamping shaft is connected to a clamping motor on a rotating seat via a clamping transmission structure. A clamping output pulley is sleeved on the output shaft of the clamping motor. A clamping rotating pulley is sleeved below the clamping shaft. The clamping transmission structure includes clamping transmission pulleys sleeved on a shaft and capable of rotating relative to each other. The clamping transmission pulley and the clamping rotating pulley are connected by a clamping rotating belt. The clamping transmission pulley and the clamping output pulley are connected by a clamping transmission belt. The clamping rotating belt and the clamping transmission belt are located at the upper and lower parts of the clamping transmission pulley, respectively.

[0012] The preferred clamping transmission structure uses a sleeve shaft as the transmission shaft, which ensures that the swing arm and the clamping rotating belt are basically parallel. This state can be maintained during the swinging of the swing arm, which can avoid interference and ensure that the clamping rotating belt does not become loose.

[0013] Preferably, the end of the swing arm has a hole for installing the clamping shaft and a slot that connects to the hole at a right angle to divide the swing arm into two parts, and the two parts are locked together by locking holes and bolts; the end of the clamping block that is sleeved on the clamping shaft has a hole for sleeved on the clamping shaft and a slot that connects to the hole at a right angle to divide the clamping block into two parts, and the two parts are locked together by locking holes and bolts.

[0014] This preferred design divides the end of the swing arm and the end of the clamping block into two parts, and uses bolts with locking holes to deform and lock the two parts together. This ensures a secure installation while facilitating disassembly, and also allows for adjustment of the height of the clamping block to accommodate reel packaging trays of different widths.

[0015] Preferably, the rotating shaft is a stepped shaft, with the upper step used to support the placed turntable, and a rotating block is inserted into the side of the rotating shaft and locked by bolts. The reel packaging tray has an insertion port that cooperates with the rotating block.

[0016] This preferred solution, through the design of the rotating locking block, not only facilitates the placement and removal of the reel packaging tray, but also ensures that the reel packaging tray rotates synchronously with the rotating shaft by cooperating with the slot on the reel packaging tray.

[0023] 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.

[0024] like Figure 1-4 As shown, the specific structure of the present invention is as follows: a rotating clamping mechanism for packaging reel packaging trays with protective tape, including a rotating base 11, the rotating base 11 being connected to a rotating shaft 13 via a rotating motor 12, and a turntable 14 for carrying reel packaging trays 4 being mounted on the rotating shaft. The rotating shaft 13 is characterized by having a sleeve 16 that can rotate relative to it, the sleeve 16 being fitted with a swing arm drive structure, and a swing arm 17 being fixedly sleeved on the sleeve 16. The swing arm 17 is located below the turntable 14, and the outer end of the swing arm 17 extends beyond the reel packaging tray 4 on the turntable 14. The end is provided with a clamping device that cooperates with the reel packaging tray 4 on the turntable 14. The clamping device is used to press the protective tape into the reel packaging tray. The swing arm drive structure includes a swing arm transmission pulley 22 fixedly sleeved on the bushing 16 and a swing arm motor 20 set on the rotating seat 11. A swing arm output pulley 21 is sleeved on the output shaft of the swing arm motor 20. The swing arm output pulley 21 and the swing arm transmission pulley 22 are connected by a swing arm transmission belt 23. After the swing arm motor 20 and the rotating motor 12 are started, they both rotate at a fixed speed, and the rotating shaft 13 and the bushing 16 rotate at the same speed.

[0025] Figure 1 This shows the cooperation state between the rotating clamping mechanism 3 and the reel packaging tray 4 of this application. In actual working process, it is necessary for the clamping device to rotate relative to the rotating shaft 13, and it is also necessary for the clamping device 13 to rotate synchronously with the rotating shaft 13. The solution of this application limits the rotation speed of the rotating shaft 13 and the sleeve shaft 16 to be the same in order to ensure that the two rotate synchronously. In order to achieve this effect, in practical applications, the simplest way is to make the transmission ratio between the swing arm drive pulley and the swing arm output pulley 1:1. In this way, it is only necessary to set the swing arm motor 20 and the rotating motor 12 to rotate at the same fixed speed.

[0026] The actual operation of the rotating clamping mechanism 3 of this application is as follows: First, the reel packaging tray 4 is placed from the upper end of the rotating shaft 13 onto the turntable 14, completing the feeding of the reel packaging tray 4. Then, in conjunction with the protective tape feeding mechanism, the protective tape is clamped. The end of the protective tape will enter the clamping area. Then, the swing arm motor 20 drives the sleeve shaft 16 to rotate through the transmission structure, which in turn drives the swing arm 17 on the sleeve shaft 16 to rotate. Then, the clamping device presses the end of the protective tape slightly behind onto the reel packaging tray 4. Then, the swing arm motor 20 and the rotating shaft 14 are started simultaneously. The motor 12 rotates synchronously, causing the reel packaging tray and the clamping device to rotate nearly one revolution. At this point, the end of the clamped protective tape will be pressed down by the subsequent protective tape. Simply reverse the swing arm motor 20 to drive the swing arm 17 to rotate in the opposite direction, so that the clamping device can move to the position where the end of the protective tape is pressed down by the subsequent protective tape. The clamping device will then press down the protective tape. After that, simply cut the protective tape to complete the protective tape winding of the reel packaging tray. Finally, seal the outer end of the protective tape with glue to complete the entire process of wrapping the protective tape of the reel packaging tray.

[0027] like Figure 2-5 As shown, the clamping device includes a clamping shaft 18 mounted on a swing arm 17 via a bearing seat and parallel to the rotating shaft 13. A clamping block 19 is mounted on the clamping shaft 18 and rotates with it. The lower part of the clamping shaft 18 is connected to a clamping motor 27 on a rotating seat 11 via a clamping transmission structure. A clamping output pulley 28 is sleeved on the output shaft of the clamping motor 27. A clamping rotating pulley 24 is sleeved below the clamping shaft 18. The clamping transmission structure includes a clamping transmission pulley 25 sleeved on a sleeve shaft 16 and capable of rotating relative to it. The clamping transmission pulley 25 and the clamping rotating pulley 24 are connected by a clamping rotating belt 26. The clamping drive pulley 25 and the clamping output pulley 28 are connected by the clamping drive belt 29, and the clamping rotating belt 26 and the clamping drive belt 29 are located at the upper and lower parts of the clamping drive pulley 25, respectively. The end of the swing arm 17 is provided with a hole for installing the clamping shaft and a slot that connects to the hole at a right angle to divide the swing arm 17 into two parts. The two parts are locked by locking holes 30 and bolts. The clamping block 19 is sleeved on the end of the clamping shaft 18 and is provided with a hole for sleeved on the clamping shaft and a slot that connects to the hole at a right angle to divide the clamping block 19 into two parts. The two parts are locked by locking holes 30 and bolts.

[0028] Before starting work, adjust the height of the clamping block 19 according to the corresponding width specifications of the reel packaging tray 4 and the protective tape. Specifically, first loosen the bolts in the locking hole 30, adjust the height, and then tighten the bolts. Next, perform the protective tape wrapping operation. During the independent rotation of the swing arm, the clamping block 19 is in a non-clamping state. When clamping is required, the clamping motor 27 drives the clamping drive pulley 25 to rotate relative to the sleeve shaft 16 through the transmission structure, and then drives the clamping shaft 18 to rotate through the transmission structure. The clamping block 19 can be driven to rotate, so that the clamping block 19 clamps the protective belt. In the clamping structure of this application, the sleeve shaft 16 is used as the transmission center shaft. When the swing arm 17 drives the clamping device to rotate as a whole, since the clamping rotating belt 26 is basically parallel to the swing arm 17, the rotation of the swing arm 17 will not cause the clamping transmission pulley 25 to rotate. Only the engagement part of the clamping rotating belt 26 and the clamping transmission pulley 25 will change. This can ensure that the swing arm 17 and the clamping device can work independently without interfering with each other.

[0029] like Figure 1 and Figure 5 As shown, the rotating shaft 13 is a stepped shaft, with the upper step used to support the placed turntable 14, and a rotating locking block 15 is inserted into the side of the rotating shaft 13 and locked with bolts. The reel packaging tray 4 has an insertion port that cooperates with the rotating locking block 15.

[0030] The reel packaging tray 4 is first inserted into the upper part of the rotating shaft 13, and its insertion port is aligned with the position of the rotating block 15. Then, simply place the reel packaging tray 4 on the turntable 14, and the rotating block 15 and the insertion port will make the reel packaging tray 4 rotate synchronously with the rotating shaft 13.
