Description

Technical Field

[0001] The invention relates to the field of packaging equipment for reel packaging trays, in particular to a protective tape winding device for reel packaging trays. Background Art

[0002] In the semiconductor industry, tape and reel (reel, material reel, reel, drum) are the main packaging materials for IC and are important products for IC storage, transportation and back-end supply. Tape, also called IC tape, is a kind of tape that can decorate multiple electronic components with a tape, and then the tape is wound on a reel.

[0003] At present, after the integrated circuit chip is taped into a roll, it is usually necessary to wrap it with a protective tape and seal the joints of the protective tape. After the disc-shaped chip has been manually inspected and re-inspected, a protective tape of a certain length is manually taken, and after it is wrapped around the reel once, the tape is pasted on the joints of the protective tape. The protective tape can better protect the chip and prevent it from being damaged. In addition, the protective tape can also prevent the chip from being damaged during transportation.

[0004] In order to improve the packaging efficiency of the reel packaging tray, a mechanical mechanism is used instead of manually winding the protective belt. A rotatable turntable carries the reel packaging tray, and presses the protective belt on the reel packaging tray and rotates synchronously or relatively therewith, and can adjust the clamping or loosening state, and is matched with a protective belt feeding device that can automatically feed the material. The protective belt feeding device needs to send the end to the reel packaging tray, and then be clamped and rotated so that the end is clamped by the subsequent part of the protective belt, and then the subsequent part is clamped and the protective belt is cut off. However, the existing protective belt feeding device has certain defects. The cutting part is located at the part of the entire device closest to the reel packaging tray. If the position of the reel packaging tray is designed too close, it is easy to interfere. If it is designed far away, the distance between the reel packaging tray and the incision is large, and the protective belt may fall off due to gravity deformation after cutting. Summary of the invention

[0005] The object of the present invention is to provide a protective tape winding device for a reel packaging tray, in which the cut portion is arranged in a protective tape feeding seat, and through the structural design of the conductive block, it is ensured that the cut protective tape can be inserted into the conductive block and sent to the reel packaging tray, thereby avoiding interference and preventing the cut protective tape from being deformed and falling due to gravity due to the large spacing.

[0006] In order to achieve the above objectives, the technical solution adopted by the present invention is: a protective tape winding device for a reel packaging tray, comprising a workbench and a rotating clamping mechanism and a protective tape feeding mechanism arranged on the workbench, the rotating clamping mechanism is used to place the reel packaging tray and clamp the protective tape sent by the protective tape feeding mechanism on the reel packaging tray, the protective tape feeding mechanism comprises a protective tape guide wheel and a protective tape feeding seat arranged on the workbench, the protective tape feeding seat is provided with a protective tape conveying structure for conveying the protective tape and a conductive block for guiding the conveying direction of the protective tape, the protective tape passes through the partition, conductive block and outer plate in the protective tape feeding seat, and a protective tape cutting structure composed of a protective tape cutting cylinder and a protective tape cutting knife is arranged between the protective tape conveying structure and the conductive block, the side of the conductive block close to the protective tape cutting structure is a concave cone, and the tip of the concave cone is a guide groove for the protective tape to pass through.

[0007] This solution ensures that the cut protective belt can enter the guide groove of the conductive block through the conductive block and its concave cone-shaped structural design, eliminating the influence of the protective belt cutting structure on the protective belt feeding. In this way, the protective belt cutting structure can be installed in the protective belt feeding seat, which can avoid interference while not increasing the distance between the protective belt feeding seat and the reel protective plate. After the protective belt is cut, the cut part of the protective belt can still be supported. Only when the protective belt is completely separated from the protective belt feeding seat will it have no supporting effect. The length of the protective belt after complete separation is small, so there will be no downward deformation due to gravity.

[0008] Preferably, the protective belt conveying structure includes a protective belt feeding drum and a feeding pressing drum that cooperate with each other. The protective belt feeding drum is driven by the protective belt feeding motor through a transmission structure. A feeding pressing cylinder is provided on the protective belt feeding seat. The feeding pressing cylinder is connected to a feeding pressing movable seat. The feeding pressing roller is installed on the feeding pressing movable seat.

[0009] The preferred solution designs the feeding and pressing roller to be adjustable, which not only facilitates the protective belt in the initial state to enter the protective belt conveying structure, but also can adapt to protective belts of different thicknesses.

[0010] The rotating clamping mechanism includes a rotating seat arranged on a workbench, the rotating seat is connected to a rotating shaft through a rotating motor, a rotating disk carrying a reel packaging disk is installed on the rotating shaft, a sleeve shaft that can rotate with each other is sleeved on the rotating shaft, the sleeve is matched with a swing arm driving structure, the sleeve shaft is fixedly sleeved with a swing arm, the swing arm is located below the rotating disk, and the outer end of the swing arm exceeds the reel packaging disk on the rotating disk, and a clamping device that cooperates with the reel packaging disk on the rotating disk is arranged on the outer end of the swing arm, and the clamping device is used to press the protective belt into the reel packaging disk.

[0011] The swing arm rotation center structure sleeve of the preferred solution is sleeved on the rotating shaft of the reel packaging plate. The rotation of the swing arm and the rotation of the reel packaging plate have good coaxiality. The rotation of the clamping device is achieved through the swing arm. Compared with the existing track structure, the structure is simple and the error is smaller.

[0012] Preferably, the swing arm driving structure includes a swing arm transmission pulley fixedly sleeved on the shaft sleeve and a swing arm motor arranged on the rotating seat, a swing arm output pulley is sleeved on the output shaft of the swing arm motor, and the swing arm conveyor pulley and the swing arm transmission pulley are connected by a swing arm transmission belt.

[0013] Preferably, the swing arm motor and the rotating motor both rotate at a fixed speed after being started, and the rotating shaft and the sleeve shaft have the same speed.

[0014] This preferred solution fixes the rotation speed of the swing arm motor and the rotating motor, so that the transmission ratio and the rotation speed of the swing arm motor and the rotating motor can be used to ensure the synchronous rotation of the rotating shaft and the sleeve, thereby ensuring that the clamping point will not move relative to the reel packaging plate when the reel packaging plate and the clamping structure are clamped.

[0015] Preferably, the clamping device includes a clamping shaft installed on the swing arm through a bearing seat and parallel to the rotating shaft, a clamping block rotating therewith is installed on the clamping shaft, the lower part of the clamping shaft is connected to the clamping motor on the rotating seat through a clamping transmission structure, the output shaft of the clamping motor is sleeved with a clamping output pulley, a clamping rotating pulley is sleeved below the clamping shaft, the clamping transmission structure includes a clamping transmission pulley sleeved on the sleeve 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, and the clamping rotating belt and the clamping transmission belt are respectively located at the upper and lower parts of the clamping transmission pulley.

[0016] The clamping transmission structure of the preferred embodiment uses a sleeve shaft as the transmission shaft, which can ensure that the swing arm and the clamping rotating belt are in a basically parallel state. This state can always be maintained during the swinging of the swing arm, which can avoid interference and ensure that the clamping rotating belt will not loosen.

[0017] Preferably, the end of the swing arm is provided with a hole for installing the clamping shaft and a notch connected to the hole at a right angle to divide the swing arm into two parts, and the two parts are locked by a locking hole and a bolt; the end of the clamping block is sleeved on the clamping shaft and is provided with a hole for sleeved the clamping shaft and a notch connected to the hole at a right angle to divide the clamping block into two parts, and the two parts are locked by a locking hole and a bolt.

[0018] The preferred solution is to split the end of the swing arm and the end of the clamping block into two parts, and deform and lock the two halves through locking holes and bolts, so that it can ensure a tight installation while facilitating disassembly, and the height of the clamping block can also be adjusted to adapt to reel packaging trays of different widths.

[0019] Preferably, the rotating shaft is a stepped shaft, the upper step is used to support the placed turntable, and a rotating block is inserted into the side of the rotating shaft and locked by bolts, and a socket that cooperates with the rotating block is opened on the reel packaging plate.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0030] like Figure 1-3 As shown, the specific structure of the present invention is: a protective tape winding device for a reel packaging tray, comprising a workbench 2 and a rotating clamping mechanism 3 and a protective tape feeding mechanism 5 arranged on the workbench 2, the rotating clamping mechanism is used to place the reel packaging tray 5 and clamp the protective tape sent by the protective tape feeding mechanism 5 on the reel packaging tray 5, and is characterized in that the protective tape feeding mechanism 5 comprises a protective tape guide wheel 32 and a protective tape feeding seat 31 arranged on the workbench 2, the protective tape feeding seat 31 is provided with a protective tape conveying structure for conveying the protective tape 33 and a conductive block 39 for guiding the conveying direction of the protective tape 33, the protective tape 33 passes through the partition, the conductive block 39 in the protective tape feeding seat 31, and the protective tape 33 passes through the partition, the conductive block 39 in the protective tape feeding seat 31. The guide block 39 and the outer plate, and a protective belt cutting structure composed of a protective belt cutting cylinder 40 and a protective belt cutting knife 41 is arranged between the protective belt conveying structure and the conductive block 39, the side of the conductive block 39 close to the protective belt cutting structure is a concave cone, and the tip of the concave cone is a guide groove for the protective belt 33 to pass through, the protective belt conveying structure includes a protective belt feeding drum 35 and a feeding clamping drum 38 that cooperate with each other, the protective belt feeding drum 35 is driven by the protective belt feeding motor 34 through the transmission structure, and a feeding clamping cylinder 36 is arranged on the protective belt feeding seat 31, and the feeding clamping cylinder 36 is connected to a feeding clamping movable seat 37, and the feeding clamping roller 38 is installed on the feeding clamping movable seat 37.

[0031] When in use, first place the reel packaging tray 4 on the rotating clamping mechanism 3, then place a roll of protective tape, and then pull out the end so that the end of the protective tape 33 passes through the protective tape guide wheel 32 and enters between the protective tape feeding roller 35 and the feeding pressing roller 38, and then the feeding pressing movable seat 37 is driven to move by the feeding pressing cylinder 36 so that the feeding pressing roller 38 presses the protective tape 33 on the protective tape feeding roller 35 to complete the preparation of the protective tape. When the protective tape needs to be wound, the protective tape feeding motor 34 drives the protective tape feeding roller 35 to rotate to realize the transportation of the protective tape 33. The protective tape will first pass through the partition on the protective tape feeding seat 31 and then enter the guide groove in the conduction block 39, and then pass through the outer plate of the protective tape feeding seat 31 and continue to move a distance to the reel packaging tray 4. In order to ensure the best matching of the protective tape 33 and the reel packaging tray 4 To achieve the desired effect, the delivered protective belt 33 can be designed to be tangent to the reel packaging disk 4, and then the rearward portion of the end of the protective belt 33 can be clamped on the reel packaging disk 4 by means of a rotating clamping mechanism, and then the rotating reel packaging disk and the clamping part are driven to rotate synchronously for nearly one circle. While rotating, the protective belt feeding motor 34 drives the protective belt feeding roller 35 to rotate to continuously convey the protective belt 33. After rotating for nearly one circle, the end of the protective belt 33 will be pressed by the subsequent protective belt. In this way, the clamping part of the rotating clamping mechanism is moved alone to the end of the protective belt to clamp the protective belt, and then the protective belt cutting knife 41 can be driven by the protective belt cutting cylinder 40 to cut the protective belt 33, and then the rotating clamping mechanism drives the rotating reel packaging disk and the clamping part to rotate synchronously, and the protective belt 33 is pasted and sealed with masking glue to complete the winding of the protective belt of the reel packaging disk.

[0032] like Figure 4-6 The rotating clamping mechanism shown comprises a rotating seat 11 on a workbench 2, the rotating seat 11 is connected to a rotating shaft 13 through a rotating motor 12, a rotating disc 14 carrying a reel packaging disc 4 is mounted on the rotating shaft, and is characterized in that a sleeve shaft 16 which can rotate with each other is sleeved on the rotating shaft 13, the sleeve shaft 16 is matched with a swing arm driving structure, a swing arm 17 is fixedly sleeved on the sleeve shaft 16, the swing arm 17 is located below the rotating disc 14, and the outer end of the swing arm 17 exceeds the reel packaging disc 4 on the rotating disc 14, and a swing arm 17 is arranged on the outer end of the swing arm 17 to be connected to the rotating disc 14. The reel packaging tray 4 is matched with a clamping device, which is used to press the protective tape into the reel packaging tray; the swing arm driving structure includes a swing arm transmission pulley 22 fixedly sleeved on the shaft sleeve 16 and a swing arm motor 20 arranged 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 conveyor pulley 21 and the swing arm transmission pulley 22 are connected by a swing arm transmission belt 23, and the swing arm motor 20 and the rotating motor 12 both rotate at a fixed speed after starting, and the rotating shaft 13 and the sleeve shaft 16 have the same speed.

[0033] In actual working engineering, the clamping device is required to rotate relative to the rotating shaft 13, and the clamping device 13 is also required to rotate synchronously with the rotating shaft 13. The scheme of the present application limits the rotating shaft 13 and the sleeve shaft 16 to the same rotation speed in order to ensure that the two rotate synchronously. In order to achieve this effect, in actual application, the simplest way is to make the transmission ratio between the swing arm drive pulley and the swing arm conveyor pulley 1:1, so that it is only necessary to set the swing arm motor 20 and the rotating motor 12 to rotate at the same fixed speed.

[0034] The actual working of the rotating clamping mechanism 3 of the present application is as follows: first, the reel packaging disk 4 is placed from the upper end of the rotating shaft 13 onto the turntable 14 to complete the discharge of the reel packaging disk 4, and then the protective belt feeding mechanism is cooperated to clamp the protective belt, and the end of the protective belt will enter the clamping area, and then the swing arm motor 20 drives the sleeve shaft 16 to rotate through the transmission structure, so that the swing arm 17 on the sleeve shaft 16 can be driven to rotate, and then the clamping device presses the end of the protective belt on the reel packaging disk 4 at a slightly rearward position, and then the swing arm motor 20 and the rotating disk are synchronously started. The driving motor 12 rotates synchronously, so that the reel packaging disk and the clamping device rotate synchronously for nearly one circle. At this time, the end of the clamped protective belt will be pressed by the subsequent protective belt. It only needs to reverse the swing arm motor 20 to drive the swing arm 17 to rotate in the opposite direction, so that the clamping device can be moved to the position where the end of the protective belt is pressed by the subsequent protective belt, and the protective belt is pressed by the clamping device. After that, it only needs to cut off the protective belt to complete the winding of the protective belt of the reel packaging disk, and then the outer end of the protective belt is sealed with glue to complete the entire process of winding the protective belt of the reel packaging disk.

[0035] like Figure 4-7As shown, the clamping device includes a clamping shaft 18 mounted on the swing arm 17 through a bearing seat and parallel to the rotating shaft 13, a clamping block 19 rotating therewith is mounted on the clamping shaft 18, the lower part of the clamping shaft 18 is connected to the clamping motor 27 on the rotating seat 11 through a clamping transmission structure, the output shaft of the clamping motor 27 is sleeved with a clamping output pulley 28, a clamping rotating pulley 24 is sleeved below the clamping shaft 18, the clamping transmission structure includes a clamping transmission pulley 25 sleeved on the sleeve shaft 16 and capable of rotating relative to each other, 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 through the clamping drive belt 29, and the clamping rotating belt 26 and the clamping drive belt 29 are respectively located at the upper and lower parts of the clamping drive pulley 25, and the end of the swing arm 17 is provided with a hole for installing the clamping shaft and a notch connected to the hole at a right angle to divide the swing arm 17 into two parts, and the two parts are locked by a locking hole 30 and a bolt; the clamping block 19 is sleeved on the end of the clamping shaft 18 and is provided with a hole for sleeved the clamping shaft and a notch connected to the hole at a right angle to divide the clamping block 19 into two parts, and the two parts are locked by a locking hole 30 and a bolt.

[0036] Before work, the height of the clamping block 19 is adjusted according to the reel packaging plate 4 and the protective tape of the corresponding width specifications. Specifically, the bolts in the locking holes 30 are loosened first, and then the bolts are tightened after adjustment. Then the protective tape winding operation is performed. During the rotation of the swing arm alone, the clamping block 19 is in a non-clamping state. When clamping is required, the clamping drive pulley 25 is driven to rotate relative to the sleeve shaft 16 through the clamping motor 27 through the transmission structure, and then the clamping shaft 18 is driven to rotate through the transmission structure. It can drive the clamping block 19 to rotate, so that the clamping block 19 clamps the protective belt. The clamping structure of the present application uses the sleeve shaft 16 as the transmission center axis. 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 connection position of the clamping rotating belt 26 and the clamping transmission pulley 25 will change, which can ensure that the swing arm 17 and the clamping device can work independently without interfering with each other.

[0037] like Figure 7 As shown, the rotating shaft 13 is a stepped shaft, the upper step is used to support the placed turntable 14, and a rotating block 15 is inserted into the side of the rotating shaft 13 and locked by bolts, and a socket that cooperates with the rotating block 15 is opened on the reel packaging plate 4.

[0038] The reel packaging tray 4 is first inserted from the upper part of the rotating shaft 13, and the socket on it is made to correspond to the position of the rotating block 15. In this way, the reel packaging tray 4 only needs to be placed on the rotating disk 14, and the reel packaging tray 4 can be driven to rotate synchronously with the rotating shaft 13 through the cooperation between the rotating block 15 and the socket.

The above examples are only used to help understand the methods and core ideas of the present invention. The above is only a preferred implementation of the present invention.
