[0036] Now, various exemplary embodiments of the present utility model will be described in detail with reference to the drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps described in these embodiments do not limit the scope of the present utility model.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present utility model, its application, or use.

[0038] Technologies and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies and devices should be regarded as part of the specification.

[0039] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it will not be further discussed in subsequent figures.

[0041] In order to solve the problem that the existing equipment has a low accuracy of inserting the tape into the reel, resulting in low production efficiency. The present utility model provides a disk threading device, in combination with Figures 1 to 6 As shown, specifically, the disk threading device includes: a reel picking and placing assembly 10, a positioning assembly 20, and a tape conveying assembly 30; the reel picking and placing assembly 10 includes a loading tray movable along a first direction, and the loading tray is used to carry and fix a reel 5; the positioning assembly 20 includes a positioning disk 21 movable along a second direction; in the vertical plane where the disk body 111 of the loading tray is located, the first direction and the second direction are orthogonally arranged; the axial directions of both the loading tray and the positioning disk 21 are the first direction; both the loading tray and the positioning disk 21 include a positioning station within their respective stroke ranges; at the positioning station, the loading tray and the positioning disk 21 are coaxially arranged to achieve the alignment of the loading tray and the positioning disk 21, and the loading tray and the positioning disk 21 are respectively attached to two opposite disk surfaces of the reel 5. By moving the loading tray along the first direction close to the positioning disk 21, the positioning disk 21 is used to push the reel 5 on the loading tray so that the reel 5 is attached to the disk surface of the loading tray facing the positioning disk 21 and is fixed by the fixing member 112 of the loading tray, thereby realizing the consistency and stability of the position of the reel 5 on the loading tray; the tape conveying assembly 30 is used to cooperate with the reel 5 attached and fixed to the loading tray so that the end of the tape moves along the tape conveying direction into the slot of the reel 5. It should be noted that, in combination with Figure 1 As shown, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction; a slot for inserting one end of the tape is formed on the reel 5. Before winding the tape, it is necessary to first insert the tape into the above slot, and then complete the winding of the tape by rotating the reel 5.

[0042] In the above embodiments, the tape conveying assembly 30 includes a guiding structure for guiding the tape. By using this guiding structure, the head end of the tape can be accurately inserted into the tape slot. Specifically, the guiding structure includes a cover plate 311 and a bottom plate 312, and the cover plate 311 and the bottom plate 312 are fixed. When the cover plate 311 and the bottom plate 312 are closed, an internal track of the guiding structure is formed between the cover plate 311 and the bottom plate 312 to guide and limit the tape. Under the limitation of the guiding structure, the tape can move along the extending direction of the internal track within the internal track to improve the accuracy of inserting the head end of the tape into the reel slot.

[0043] Further, a groove 313 penetrating along the tape conveying direction is formed on one side of the bottom plate 312 close to the cover plate 311, and a limiting edge 314 extending upward is provided on the bottom plate 312 for limiting the tape. Specifically, a groove 313 penetrating along the tape conveying direction and two limiting edges 314 extending upward are formed on the upper surface of the bottom plate 312. The groove 313, the limiting edge 314 and the lower surface of the cover plate 311 enclose to form the above internal track. The groove 313 is formed by downward depression of a part of the upper surface of the bottom plate 312 to accommodate the tape pocket, the limiting edge 314 extends along the length direction of the bottom plate 312, and the two limiting edges 314 are arranged along the width direction of the bottom plate. The groove 313 is used to limit the pocket of the chip. Through the arrangement of the two limiting edges 314 on the bottom plate 312, the placement of the tape is limited, ensuring that the tape moves smoothly within the internal track and the head end of the tape will not shift in position after extending out of the internal track.

[0044] In a specific embodiment, the tape conveying assembly 30 further includes a tape flow channel 32 for carrying the tape and communicating with the internal track of the guiding structure, and a first driving mechanism 33 for driving the tape to move within the tape flow channel 32 and the internal track of the guiding structure; the first driving mechanism 33 is configured to move the end of the tape along the tape conveying direction outside the guiding structure. Specifically, the first driving mechanism 33 can be a driving motor with a driving wheel arranged on a rotating shaft. The tape flow channel 32 is used to carry the tape, and the tape can move within the tape flow channel 32 and the internal track under the drive of the first driving mechanism 33. The tape flow channel 32 is arranged along the tape conveying direction. One end of the tape flow channel 32 includes a tape feeding port, and the other end is connected to the above guiding structure. Before the tape is inserted into the slot of the reel 5, the guiding structure is first docked with the slot of the reel 5, so that the end of the tape for cooperating with the slot can be accurately and stably inserted into the slot.

[0045] In a specific embodiment, the tape conveying assembly 30 further includes a rotation adjustment mechanism 34 for driving the guiding structure to rotate about the first direction. By using the rotation adjustment mechanism 34 to drive the guiding structure to rotate, the end of the guiding structure close to the reel 5 enters the reel 5 at a certain angle and its internal track is docked and conducted with the slot of the reel 5, ensuring that the head end of the tape extending from the end of the guiding structure can accurately penetrate into the tape slot.

[0046] More specifically, the rotation adjustment mechanism 34 is a closed-loop motor. The guiding structure is arranged on the rotating shaft of the closed-loop motor. The rotating shaft of the closed-loop motor is arranged along the first direction, and the guiding structure extends along the third direction. By rotating the closed-loop motor, the guiding structure is driven to rotate about the first direction to adjust the angle at which the head end of the tape enters the reel 5. The closed-loop motor has the advantages of high precision, high stability and strong reliability. It can sense the actual working state of the motor in real time through closed-loop feedback and make adjustments according to the feedback data to ensure the accuracy of inserting the tape into the reel slot.

[0047] In a specific embodiment, the tape threading device further includes a mounting substrate 41, a first moving plate 42 arranged on the mounting substrate 41 and a second moving plate 43 arranged on the first moving plate 42. The tape conveying assembly 30 is arranged on the second moving plate 43. The first moving plate 42 is configured to be movable along the third direction on the mounting substrate 41, and the second moving plate 43 is configured to drive the tape conveying assembly 30 to move along the first direction on the first moving plate 42. The third direction is perpendicular to both the first direction and the second direction. By adjusting the first moving plate 42 and the second moving plate 43, the position of the guiding structure in the third direction and the first direction can be adjusted, so that the guiding structure can be aligned with the reel 5 fixed on the loading tray, and the tape can accurately enter the slot. More specifically, a first strip-shaped hole 44 extending along the third direction is arranged on the first moving plate 42. The first moving plate 42 realizes the position adjustment on the mounting substrate 41 by means of bolts passing through the first strip-shaped hole 44, that is, when the bolts are loosened, the first moving plate 42 is pushed to move along the third direction, and after reaching the position, the bolts are tightened to fix the position of the first moving plate 42 on the mounting substrate 41. Similarly, a second strip-shaped hole 45 extending along the first direction is arranged on the second moving plate 43. The second moving plate 43 realizes the position adjustment on the first moving plate 42 by means of bolts passing through the second strip-shaped hole 45, that is, when the bolts are loosened, the second moving plate 43 is pushed to move along the first direction, and after reaching the position, the bolts are tightened to fix the position of the second moving plate 43 on the first moving plate 42.

[0048] In a specific embodiment, the pick-and-place reel assembly 10 further includes a rotating mechanism 12 for driving the material-carrying disk to rotate about the first direction, a third driving mechanism 13 with a driving end reciprocating along the first direction, and a suction member 14 reciprocating along the first direction. The suction member 14 is driven by a pick-and-place cylinder 15 to move along the first direction to transfer the reel 5 onto the material-carrying disk. The suction member 14 can be a vacuum chuck. The third driving mechanism 13 is used to drive the material-carrying disk to reciprocate along the first direction. The rotating mechanism 12 can specifically be a rotating motor, and the third driving mechanism 13 can specifically be a pick-up cylinder. The pick-up cylinder can drive the material-carrying disk to reciprocate along the first direction. The material-carrying disk can move along the first direction close to the positioning disk 21 after alignment therewith and cooperate with the positioning disk 21 to clamp the reel 5 between the material-carrying disk and the positioning disk 21, so that the reel 5 fits on the disk surface of the material-carrying disk facing the reel 5, thereby solving the problem of inconsistent positions of the reels on the material-carrying disk and improving the success rate of threading the tape into the reels.

[0049] In a specific embodiment, the material-carrying disk includes: a disk body 111 with a through hole opened at the center thereof; a fixing member 112; and a driving member 113 passing through the through hole and connected to the fixing member 112 for driving the fixing member 112 to fix to or separate from the reel 5. The fixing member 112 can specifically be a claw, and the driving member 113 can specifically be a triangular chuck cylinder. The claw is controlled by the triangular chuck cylinder to tighten or open, thereby completing the picking-up, placing, and fixing of the reel. The above-mentioned claw is used in cooperation with the triangular chuck cylinder to limit the reel 5 so that it does not shake in the circumferential direction, and the success rate of threading the tape into the reel is improved.

[0050] To realize the movement of the positioning disk 21 in the second direction, the positioning assembly 20 further includes a fourth driving mechanism 22 with a driving end reciprocating along the second direction. The positioning disk 21 is disposed at the driving end of the fourth driving mechanism 22. The fourth driving mechanism 22 can specifically be a positioning cylinder. The cylinder rod of the fourth driving mechanism 22 drives the positioning disk 21 to move downward to achieve alignment with the material-carrying disk. After the positioning operation of the reel 5 is completed, the fourth driving mechanism 22 drives the positioning disk 21 to move upward to avoid interference with subsequent operations.

[0051] The working process of the reel threading device of the present utility model is as follows:

[0052] The driving member 113 drives the fixing member 112 to tighten. At this time, the spool 5 can pass through the fixing member 112 and contact the disk body 111. The third driving mechanism 13 drives the material loading disk to extend, the picking and placing cylinder 15 drives the adsorbing member 14 to extend, the adsorbing member 14 adsorbs the spool 5, and the picking and placing cylinder 15 drives the adsorbing member 14 and the spool 5 to retract, so that the spool 5 is sleeved on the fixing member 112. When the spool 5 is located behind the fixing member 112, the driving member 113 will extend in the X direction to drive the fixing member 112 to open and thus fix the spool 5. The third driving mechanism 13 drives the material loading disk to retract, and the driving member 113 drives the fixing member 112 to tighten again. At this time, the spool 5 is in a free state. The fourth driving mechanism 22 of the positioning component 20 drives the positioning disk 21 to extend, so that the center of the positioning disk 21 is aligned with the center of the disk body 111. The third driving mechanism 13 drives the material loading disk to extend and approach the positioning disk 21, so that the spool 5 is closely attached to the disk body 111 of the material loading disk. At this time, the position consistency of the spool 5 is ensured. Then, the driving member 113 drives the fixing member 112 to open and fix the spool 5 to ensure that the spool 5 does not shake in the circumferential direction. Finally, the sensor cooperates with the rotating mechanism 12 to rotate the spool slot to a fixed angle. The closed-loop motor drives the guiding structure to rotate a certain angle and enter the spool 5. The encoder at the rear end of the closed-loop motor feeds back in a closed loop to confirm whether the guiding structure reaches the specified angle at this time. Due to the limitation of the guiding structure, it can be ensured that the tape does not run left and right when it comes out of the end opening of the guiding structure, thereby greatly improving the success rate of threading the tape into the spool 5.

[0053] In summary, through the cooperation of the picking and placing spool assembly and the positioning component, in the positioning station, the driving material loading disk and the positioning disk are coaxially arranged, and the spool on the material loading disk is pushed to move by approaching the positioning disk so that the spool fits against the disk surface of the material loading disk facing the positioning disk, so as to ensure that the position of the spool on the material loading disk can be kept stable and consistent each time the material loading disk picks up materials. Then, in cooperation with the guiding structure of the tape conveying component to guide the tape, the end of the tape can accurately move along the tape conveying direction into the spool slot on the material loading disk, improving the success rate of threading the tape into the spool, and thus improving the overall production efficiency.

[0054] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
