Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chip packaging technology, and in particular relates to a roll winding error prevention device and winding equipment. Background Technology
[0002] Chip taping refers to the process of taking bare chips or pre-packaged IC components, selecting a carrier tape of appropriate width and depth based on the chip's size, thickness, and pin distribution, and then using an IC taping machine to neatly and precisely place the chips into the carrier tape grooves at a certain spacing and direction. The chips are then sealed using methods such as heat sealing with a cover tape. Finally, a tape reel is wound onto a reel using a tape winding machine so that subsequent pick-and-place machines can perform the placement process efficiently and accurately.
[0003] For small package sizes of taped products (such as DFN): the median gap between the device inside the tap and the cover tape surface is about 60μm. During the tape winding process, layers are stacked, and the winding becomes tighter towards the inner circle. Given that the cover tape material is relatively soft, if the winding is too tight, the cover tape surface will deform and sink. The adhesive layer on the cover tape surface and the product surface will be in long-term pressure contact, causing the device to stick to the cover tape surface, affecting the effective output per hour (UPH) and the number of qualified products in the SMT plant. The device that fixes the empty reel in the traditional automatic reel unwinding and rewinding device does not have a reel orientation error prevention device. It is not easy for personnel to detect the reel orientation error. Once the reel is reversed, the taped tape in the reel will also be reversed and flow to the customer, causing customer complaints. Utility Model Content
[0004] To address the problems in the prior art, this utility model provides a roll winding error prevention device and a winding equipment.
[0005] To achieve the above objectives, this utility model proposes a roll winding error prevention device, including a base, and further comprising: The connector is installed on the base by inserting it into the base via a reel-type shaft on the base surface. The connector is divided into a fastening area and a slack area. The anti-fooling pin is vertically set on the surface of the fastening area. After the reel is fed to the reel holding shaft, the anti-fooling pin is correspondingly set in the groove on the back of the reel to prevent the reel from being fed in the wrong direction. The slack pin is vertically positioned in the slack area and can be adjusted to change the center distance between itself and the reel holding shaft, thereby adjusting the inner diameter of the tape during reel winding.
[0006] Furthermore, the central shaft portion of the connector is hollowed out, and the reel holding shaft is inserted into the connector through the hollowed-out central shaft portion. The reel holding shaft, the foolproof pin, and the slack pin are parallel to each other and extend in the same direction.
[0007] Furthermore, the fastening area of the connecting seat also includes an opening communicating with the hollowed-out part of the central shaft. A threaded bolt A passes through the opening. The size of the hollowed-out part of the central shaft is adjusted by bolt A, so as to be close to or separate from the reel holding shaft, thereby firmly installing or separating the connecting seat from the base.
[0008] Furthermore, the relaxation area has a hollow center and an inner ring on its inner wall. The inner ring has a slider, which restricts the upper slider from moving downward. The relaxation pin is vertically disposed on the surface of the slider and is parallel to the anti-fooling pin.
[0009] Furthermore, one end of the bolt B is located below the inner ring. The inner ring restricts the upward movement of this end of the bolt B. The other end of the bolt B is screwed into the slider through a threaded connection. By adjusting the bolt B, the slider can move or be fixed on the inner ring, thereby adjusting the inner diameter of the tape when the reel is winding.
[0010] Furthermore, the relaxation area is located on the visible area of the reel on the reel holding shaft.
[0011] Furthermore, the slack pin extends from the back of the reel on the reel holding shaft through the visible area of the reel to the front of the reel.
[0012] Furthermore, the foolproof device for the reel winding is made of stainless steel.
[0013] A tape winding device includes the aforementioned tape winding error prevention device, which is mounted on the drive mechanism of the tape winding device via a base, thereby driving the tape reel to rotate for tape winding.
[0014] The beneficial effects of this utility model are: 1. By setting up a foolproof pin, the feeding reel is prevented from being inserted backwards, thus preventing customer complaints caused by the reel being in the wrong direction; 2. By setting the slack pin, the center distance between the pin and the reel holding shaft can be adjusted, the inner diameter of the tape can be adjusted when the reel is winding, there are no squeezing marks on the inner ring of the tape, and no material sticks to the cover tape when peeling off the cover tape, preventing the inner ring from being squeezed and thrown off.

[0017] The present invention will now be described in conjunction with specific embodiments, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.
[0018] The directional terms used in this utility model, such as up, down, left, right, front, back, inside, outside, front, back, side, etc., are merely for reference to the accompanying drawings. The embodiments and directional terms used in the following description with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Furthermore, the various specific processes and materials provided in this utility model are examples of applications of other processes and / or the use of other materials that those skilled in the art will recognize.
[0019] After chip products are plastic-encapsulated and cut into product units, they need to be packaged and transported. The equipment neatly and precisely places the chips into the carrier tape grooves according to a certain spacing and direction. The cover tape and carrier tape are bonded together by heat sealing and other methods to fix the chip position and prevent dust and moisture, forming a tape.
[0020] Reels are commonly used tape and reel consumables in this field. They need to be fed onto the tape winding machine during tape winding. They are usually made of plastic or high-strength paper-plastic composite material and are used to carry the wound carrier tape for easy storage, transportation and feeding to the chip mounter feeder. The reel has a hollow center, and the hollow edge matrix is provided with card interfaces. There is also a visible area on the reel. The upper and lower circular shells of the reel are connected as one piece. The recessed area in the middle of the two is the winding area. There are grooves on the back of the reel around the central matrix.
[0021] The existing feeding mechanism is a structure consisting of a base 1 and a reel holding shaft 2 (e.g.) Figure 1-3As shown in the figure, the reel holding shaft 2 is installed on the surface of the base 1. The size of the reel holding shaft 2 matches the size of the central hollow area of the reel (not shown in the figure). The reel is inserted into the reel holding shaft 2. A snap-fit block (not shown in the figure) is set on one side of the reel holding shaft 2. The snap-fit block snaps into the snap-fit interface. The base 1 is installed on the drive mechanism of the winding equipment, which drives the reel to rotate for tape winding. The snap-fit block and the reel holding shaft 2 are directly inserted into the corresponding area. The reel can be loaded normally from both the front and back. It is not easy for personnel to notice that the reel is in the wrong direction. Once the reel is reversed, the tape contained in the reel will be reversed and flow to the customer, causing customer complaints. During the tape winding process, the layers are stacked and the winding becomes tighter towards the inner circle. Since the cover tape material is relatively soft, if the winding is too tight, the surface of the cover tape will deform and sink. The glue layer on the surface of the cover tape and the product surface will be in long-term pressure contact, causing the device to stick to the surface of the cover tape, affecting the production capacity.
[0022] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figure 4 -Appendix Figure 7 The present invention provides a more detailed description of a roll winding anti-mistake device. The anti-mistake device includes a base 1, with a roll holding shaft 2 disposed on the surface of the base 1 for loading and placing the roll. The central hollow area of the roll matches the size of the roll holding shaft 2. The roll is inserted into the roll holding shaft 2 through the central hollow area. A locking block is disposed on one side of the roll holding shaft 2, and locking interfaces are provided in the matrix of the central hollow edge of the roll. The locking block engages with the locking interfaces, enhancing the secure loading of the roll.
[0023] The foolproof device also includes: The connecting seat 3 and the connecting seat 2 have a hollowed-out central shaft. The reel holding shaft 2 is inserted into the connecting seat 3 through the hollowed-out central shaft. The connecting seat 3 is installed on the base 1 by inserting the reel holding shaft 2 on the surface of the base 1.
[0024] The connecting seat 3 is divided into a fastening area 4 and a loosening area 5. The fastening area 4 of the connecting seat 3 also includes an opening 8 that communicates with the hollow part of the central shaft. A threaded bolt A9 passes through the opening 8. The size of the hollow part of the central shaft is adjusted by the bolt A9, so as to be close to or separate from the reel holding shaft 2, thereby firmly installing or separating the connecting seat 3 from the base 1.
[0025] The anti-foolproof pin 6 is vertically positioned on the surface of the fastening area 4. After the reel is loaded onto the reel holding shaft 2, the anti-foolproof pin 6 is correspondingly positioned in the groove on the back of the reel (not shown in the figure). Figure 3 and Figure 7 As shown in the figure, this is to prevent the reel from reversing during loading.
[0026] The relaxation pin 7 is vertically set in the relaxation area 5 and can adjust the center distance between it and the reel holding shaft 2 to adjust the inner diameter of the tape when the reel is winding.
[0027] The relaxation zone 5 is hollowed out in the middle and has an inner ring 10 on its inner wall. The inner ring 10 has a slider 11 on it, which restricts the upper slider 11 from moving downward. The relaxation pin 7 is vertically set on the surface of the slider 11 and is parallel to the anti-fooling pin 6. The reel holding shaft 2, the anti-fooling pin 6 and the relaxation pin 7 are parallel to each other and extend in the same direction. There is one end of the bolt B12 below the inner ring 10. The inner ring 10 restricts the upper end of the bolt B12 from moving upward. The other end of the bolt B12 is screwed into the slider 11 through a threaded engagement. By adjusting the bolt B12, the slider 11 can move or be fixed on the inner ring 10, thereby adjusting the inner diameter of the tape when the reel is wound.
[0028] After installation, the relaxation area 5 is set on the visible area of the reel on the reel holding shaft 2 (not shown in the figure, e.g., ...). Figure 2 and Figure 6 As shown), without affecting the normal and stable installation of the reel, the slack pin 7 passes through the visible area of the reel from the back of the reel on the reel holding shaft 2 to the front of the reel. The slack pin 7 crosses the recessed wrapping area in the middle of the reel, and the wrapping is stacked layer by layer on the slack pin 7.
[0029] The screw-on device for the reel is made of stainless steel and has high toughness and tensile strength.
[0030] To prevent operators from inserting empty reels backwards during the testing process, anti-misoperation pins 6 (the number of which is not limited in this invention) are installed on the fastening area 4. When the reel is inserted onto the reel holding shaft 2 in the forward direction, the anti-misoperation pins 6 are correspondingly positioned in the groove on the back of the reel. When the reel is inserted onto the reel holding shaft 2 in the reverse direction, the anti-misoperation pins 6 will not engage because the front of the reel is flat and has no groove, thus preventing the reel from being inserted backwards. The length and position of the anti-misoperation pins 6 in the fastening area 4 can be flexibly adjusted according to different reel sizes and structures to achieve the purpose of preventing the reel from being inserted backwards. In this invention, the anti-misoperation pins 6 are correspondingly positioned in the groove on the back of the reel. Based on the reels currently used by our company, to match these reels, the anti-misoperation pins 6 are set to a length of 8.5mm, a diameter of 1.5mm, and a center distance of 20mm to prevent customer complaints caused by the reel being inserted backwards.
[0031] By tightening bolt A9, the size of the hollowed-out part in the central shaft of the fastening area 4 of the connecting seat 3 is adjusted. The hollowed-out part in the central shaft of the fastening area 4 is either close to or separate from the reel holding shaft 2, thereby firmly installing or separating the connecting seat 3 from the base 1. This allows the connecting seat 3 to be installed on different bases 1, adapting to factory needs and offering high flexibility.
[0032] As the package size decreases, the amount of tape wound on the reel increases, and the inner loop of the tape winding on the reel becomes tighter. Excessive inner loop winding causes compression between the carrier tape and the cover tape, resulting in indentations on the tape and even causing the product to stick to the cover tape, leading to rejection issues for the customer (if there are compression marks on the inner loop of the tape, the device in the marked area is more likely to stick to the surface of the cover tape when the cover tape is peeled off, causing rejection). Similarly, to match the existing reels, the slack pin 7 is set to an adjustable center distance structure with a length of 12mm and a diameter of 1.5mm to prevent inner loop compression rejection.
[0033] The relaxation zone 5 is hollowed out in the middle and has an inner ring 10 on its inner wall. A slider 11 is mounted on the inner ring 10, which restricts the downward movement of the upper slider 11. One end of a bolt B12 is located below the inner ring 10, which restricts the upward movement of that end of the bolt B12. The other end of the bolt B12 is screwed into the slider 11 via a threaded connection. A relaxation pin 7 is vertically positioned on the surface of the slider 11. By adjusting the bolt B12, the slider 11 can move or be fixed on the inner ring 10, thereby adjusting the distance between the relaxation pin 7 and the center of the reel. The slack pin 7 extends from the back of the reel on the reel holding shaft 2 through the visible area of the reel to the front of the reel. The tape is stacked layer by layer on the slack pin 7. The inner diameter of the tape is adjusted when the reel is winding the tape. After the tape is finished, the reel is unloaded, and the stacked tape separates from the slack pin 7. The inner loop of the tape has room to move, so as to avoid the tape being wound too tightly and causing the material to stick. This utility model only discloses the features of this embodiment. Other embodiments that realize the adjustment of the inner diameter of the tape to prevent the tape from being wound too tightly are also within the protection scope of this utility model and are not limited thereto.
[0034] Furthermore, the slack pin 7 and the foolproof pin 6 are detachably mounted on the connector 3, such as by screwing them into the connector 3 through a threaded connection, which facilitates flexible replacement to match different reels.
[0035] This utility model also includes a winding device, which includes the above-mentioned roll winding anti-mistake device. The anti-mistake device is installed on the drive mechanism of the winding device via a base 1, which drives the roll to rotate for winding.
[0036] This utility model prevents the feeding reel from being inserted backwards by setting a foolproof pin 6, thus preventing customer complaints caused by the reel being inserted in the wrong direction. By setting a slack pin 7, the center distance between the reel and the reel holding shaft 2 can be adjusted, thereby adjusting the inner diameter of the braid when the reel is winding. There are no squeezing marks on the inner circle of the braid. When peeling off the cover tape, there is no material stuck to the cover tape, preventing the inner circle from being squeezed and thrown off. The structure is simple and easy to install, without increasing the workload of personnel.
[0037] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this utility model are protected by this utility model.
