[0016] The present invention according to the embodiments will be described below with reference to the drawings. However, it should be understood that the described embodiments are merely a part of the embodiments of the present invention and do not include all of the embodiments.

[0017] When a component is said to be attached to another component, it may be directly attached to the other component, or an intermediate component may be present. When a component is said to be "placed" on another component, it may be directly attached to the other component, or an intermediate component may be present at the same time.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention pertains. The terms used herein are for the purpose of describing specific examples only and are not intended to be limiting of the present application. As used herein, the term "or / and" includes any and all combinations of one or more of the associated listed items.

[0019] A buffer device according to an embodiment of the present invention is used to temporarily store a carrier tape on a carrier tape table. The carrier tape has a through hole, and the carrier tape table pulls the carrier tape to external equipment for processing and includes a buffer box and a buffer unit. The buffer box is for buffering the carrier tape and is attached to the carrier tape table. The buffer box has an opening, and the carrier tape is positioned within the opening. The buffer unit includes a buffer driver and a gear connected to each other. The gear is attached within the buffer box. A plurality of gears are attached circumferentially to the gear. The buffer driver drives the gear to rotate, so that the gear is positioned within the through hole. The gear moves the carrier tape into the buffer box.

[0020] In the buffer device described above, a gear is driven and rotated by a buffer driver. The gear of the gear is installed in a through-hole, so the carrier tape moves toward the buffer box in conjunction with the gear. The carrier tape temporarily stored in the buffer box allows more time to align the carrier tapes, improving alignment accuracy and eliminating the need to stop the equipment, thereby improving production efficiency.

[0021] Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] As can be seen with reference to Figures 1, 2, 3, and 4, the buffer device 100 temporarily stores the carrier tape 300 on the carrier tape table 200 and processes the carrier tape 300 in cooperation with external equipment. Optionally, the carrier tape 300 is provided on a material tray 400. The head portion of the carrier tape 300 is pulled through the carrier tape table 200 to the external equipment for processing. Optionally, the carrier table 200 is provided with a groove 201. The carrier tape 300 is provided in the groove 201. Optionally, the carrier table 200 can pull multiple carrier tapes 300 to the external equipment for processing. The carrier tape 300 is provided with through holes 301. The through holes 301 are provided at equal intervals along the longitudinal direction of the carrier tape 300.

[0023] The buffer device 100 includes a buffer box 10 for temporarily storing the carrier tape 300 and a buffer unit 20 connected to the buffer box 10 for storing the carrier tape 300 in the buffer box 10. In one embodiment, the buffer box 10 has a first width, and the carrier tape 300 has a second width. The first width and the second width are equal. Alternatively, the first width may be slightly larger than the second width. Here, the difference between the first width and the second width is d, and 1 mm≦d≦2 mm. The difference d between the first width and the second width may be any one of 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2.0 mm. Controlling the width of the buffer box 10 prevents the carrier tape 300 from being wound or folded back within the buffer box 10.

[0024] As shown in FIGS. 1 and 5 , in one embodiment, the buffer box 10 includes a connecting frame 11, a first connecting plate 12, and a second connecting plate 13. The first connecting plate 12 and the second connecting plate 13 are provided on both sides of the connecting frame 11. A carrier tape 300 is provided between the first connecting plate 12 and the second connecting plate 13. A first width is defined between the opposing surfaces of the first connecting plate 12 and the second connecting plate 13. The buffer box 10 further includes a first fixing plate 14 connected to the connecting frame 11 and abutting the first connecting plate 12, and a second fixing plate 15 connected to the connecting frame 11 and abutting the second connecting plate 13. The buffer unit 20 connects the first fixing plate 14 and the second fixing plate 15. Some of the buffer units 20 are provided between a first fixed plate 14 and a second fixed plate 15. A first width is defined between the opposing surfaces of the first fixed plate 14 and the second fixed plate 15. The provision of the first fixed plate 14 and the second fixed plate 15 facilitates installation of the buffer units 20. In one embodiment, the buffer box 10 includes a first portion 10a having an opening 101 and a second portion 10b communicating with the first portion 10a. The carrier tape 300 enters the buffer box 10 through the opening 101. Specifically, when buffering the carrier tape 300, the first portion 10a is brought into proximity with the carrier tape 300, so that the carrier tape 300 is positioned within the opening 101. The buffer unit 20 then drives and moves the carrier tape 300, causing the carrier tape 300 to enter the first section 10a through the opening 101, then enter the second section 10b from the first section 10a, and finally be stored in the second section 10b. Preferably, the first section 10a and the second section 10b extend vertically and are arranged horizontally, so that the carrier tape 300 is less likely to fall from the first section 10a after entering the second section 10b, making it easier to buffer the carrier tape 300. Also, the buffer box 10 preferably has a substantially L-shaped structure.

[0025] As can be seen with reference to FIG. 6 , in one embodiment, the buffer apparatus 100 further includes a movement unit 30 connected to the buffer box 10 for moving the buffer box 10 toward or away from the carrier tape 300. The movement unit 30 includes a first mounting plate 31, a second mounting plate 32, and a movement driver 33. The first mounting plate 31 is connected to both sides of the connection frame 11. The first mounting plate 31 is also connected to both sides of the connection frame 11 via fixed blocks 34. The fixed blocks 34 are connected to the connection frame 11 and are in contact with and connected to the first and second connecting plates 12 and 13. The first mounting plate 31 is attached to the fixed blocks 34. The second mounting plate 32 and the first mounting plate 31 are elastically connected. A movement space is defined between the second mounting plate 32 and the first mounting plate 31. Preferably, the second mounting plate 32 and the first mounting plate 31 are connected via a buffer member 35. A first slide rail 311 is provided on the first mounting plate 31, and a first slider 321 is provided on the second mounting plate 32, and the first slider 321 can slide on the first slide rail 311. A main body portion of the moving driver 33 is connected to the second mounting plate 32. A drive shaft of the moving driver 33 is connected to the first mounting plate 31 via a third mounting plate 36. The moving driver 33 drives the first mounting plate 31 to move relative to the second mounting plate 32, and moves the buffer box 10, thereby moving the carrier tape 300 toward or away from the opening 101. The distance the first mounting plate 31 moves relative to the second mounting plate 32 is the buffer distance of the buffer member 35.

[0026] In one embodiment, the buffer device 100 further includes a transfer means (not shown). When a carrier tape 300 on the carrier tape table 200 requires buffering, the transfer means moves the buffer box 10, the buffer unit 20 connected to the buffer box 10, and other components so as to move them above the carrier tape 300. Then, the movement driver 33 drives the first mounting plate 31 to move it relative to the second mounting plate 32, bringing the buffer box 10 close to the carrier tape 300 and bringing the carrier tape 300 close to the opening 101. Then, the buffer unit 20 buffers the carrier tape 300 inside the buffer box 10. The buffer unit 20 stores the remaining part of the carrier tape 300 in the material tray 400 in the buffer box 10 in advance, making it easier to find the end of the carrier tape 300 in advance. When the end of the carrier tape 300 is to be butted against the beginning of the carrier tape 300 in another material tray 400, the carrier tape 300 buffered in the buffer box 10 is pulled to an external facility for processing. By buffering the carrier tape 300 in the buffer box 10, the time required to butt the carrier tape 300 can be increased, the accuracy of the butt-up can be improved, and production efficiency can be improved without stopping the facility.

[0027] 3, 6, and 7, the buffer unit 20 includes a buffer driver 21 and a gear 22. The buffer driver 21 is fixed to the first fixed plate 14 and connected to the gear 22 to drive and rotate the gear 22. The buffer driver 21 also includes an electric motor. The buffer driver 21 and the gear 22 are connected via a synchronous belt 20a.

[0028] The gear 22 is provided in the buffer box 10 and is in contact with the carrier tape 300. The gear 22 is also provided between the first fixed plate 14 and the second fixed plate 15. A plurality of gears 221 are provided in the through holes 301 in the circumferential direction of the gear 22. A second pitch is defined between adjacent gears 221. A first pitch is defined between adjacent through holes 301. The second pitch is equal to the first pitch. When the buffer driver 21 drives and rotates the gear 22, the gear 221 is positioned in the through holes 301, and as the gear 22 continues to rotate, it carries the carrier tape 300 with it and moves it into the buffer box 10. Optionally, the gear 22 includes a rack disk.

[0029] In one embodiment, the buffer unit 20 further includes a buffer movement mechanism 23 for moving the buffer driver 21 and the gear 22 toward or away from the carrier tape 300. The buffer movement mechanism 23 includes a buffer movement driver 231, a mounting block 232, and a rotating holder 233. The buffer movement driver 231 is attached to the first fixed plate 14 on a side thereof facing away from the second fixed plate 15. A driving end of the buffer movement driver 231 is connected to the buffer driver 21 and the mounting block 232. Optionally, a fourth mounting plate 234 is provided at the driving end of the buffer movement driver 231. The fourth mounting plate 234 connects the buffer driver 21 and the mounting block 232. The mounting block 232 is slidably connected to the first fixed plate 14. Furthermore, the mounting block 232 includes a second slider 232a and a second slide rail 232b. The second slide rail 232b is attached to the side of the first fixed plate 14 that is away from the second fixed plate 15. The second slider 232a is provided slidably on the second slide rail 232b. The rotating holder 233 is connected to the mounting block 232. The gear 22 is connected to the rotating holder 233 so as to be rotatable.

[0030] When the mounting block 232 is driven by the buffer movement driver 231 to slide on the second slide rail 232b, the buffer driver 21 and the gear 22 move together with the rotating holder 233, and the gear 22 approaches or moves away from the carrier tape 300. When it is necessary to buffer the carrier tape 300, the gear 22 approaches the carrier tape 300, and the gear 221 is disposed in the through-hole 301. When buffering is completed, the gear 22 moves away from the carrier tape 300, and disengages the gear 221 from the through-hole 301.

[0031] As shown in FIGS. 3, 6, and 7, in one embodiment, the buffer device 100 further includes a tape pressure unit 40. The carrier tape 300 moves from one end of the carrier tape table 200 where the gear 22 is located to one end where the tape pressure unit 40 is located, and extends from the carrier tape table 200 to external equipment. The first and second fixing plates 14 and 15 are arranged along a first direction X. When observed from the first direction X, the rotation direction of the gear 22 and the movement direction of the carrier tape 300 are the same. When observed from the first direction X, the gear 22 rotates clockwise as the carrier tape 300 moves from the end where the gear 22 is located toward the end where the tape pressure unit 40 is located.

[0032] In one embodiment, the tape pressure unit 40 includes a tape pressure driver 41, a mounting block 42, a first connecting rod 43, and a second connecting rod 44. The mounting block 42, the first connecting rod 43, and the second connecting rod 44 are provided within the buffer box 10. More specifically, the mounting block 42, the first connecting rod 43, and the second connecting rod 44 are located between the first fixed plate 14 and the second fixed plate 15. The tape pressure driver 41 is attached to the first fixed plate 14. The mounting block 42 is connected to the tape pressure driver 41. The first connecting rod 43 is connected to the mounting block 42 so as to be rotatable. The second connecting rod 44 is connected to the first fixed plate 14 and the first connecting rod 43 so as to be rotatable. The tape presser driver 41 drives and moves the mounting block 42, and also rotates the first connecting rod 43 relative to the mounting block 42 and the second connecting rod 44, thereby moving the first connecting rod 43 closer to or farther away from the carrier tape 300. Preferably, the first connecting rod 43 is provided with a presser bar 431. The presser bar 431 is provided above the carrier tape 300, and has a gap between it and the carrier tape 300. This prevents the presser bar 431 from pressing against the carrier tape 300 and restricting movement of the carrier tape 300, and also makes it possible to regulate movement of the carrier tape 300 within the groove 201.

[0033] Furthermore, a pressure wheel 421 is provided on the mounting block 42. When the tape presser driver 41 drives the mounting block 42 to move it toward the carrier tape 300, it also rotates the first connecting rod 43 in a direction away from the carrier tape 300, and brings the pressure wheel 421 into contact with the carrier tape 300, so that when the carrier tape 300 is positioned within the recessed groove 201, the carrier tape 300 is moved to the external equipment. This prevents the processing of the external equipment from being affected due to misalignment of the carrier tape 300.

[0034] When the moving driver 33 drives the first mounting plate 31 to move it relative to the second mounting plate 32, the buffer box 10 moves in tandem with it to approach the carrier tape 300. When the carrier tape 300 is set in the opening 101, buffering of the carrier tape 300 has not yet begun, and a pressure bar 431 is provided above the carrier tape 300 to help regulate the position of the carrier tape 300. If the remaining carrier tape 300 requires buffering, the tape pressure driver 41 drives the mounting block 42 to move downward and also rotates the first connecting rod 43 in a direction away from the carrier tape 300, moving the pressure bar 431 away from the carrier tape 300 and bringing the pressure wheel 421 into contact with the carrier tape 300. The buffer unit 20 then begins buffering the carrier tape 300.

[0035] In one embodiment, the tape pressure unit 40 further includes a connecting block 45 and a guide block 46. The guide block 46 is mounted on the first fixed plate 14. The connecting block 45 is connected to the tape pressure driver 41 and the mounting block 42, and is drilled into the guide block 46. The tape pressure driver 41 drives the connecting block 45 to slide within the guide block 46, and moves the mounting block 42 to move.

[0036] Furthermore, the connecting block 45 is provided with a position restricting piece 451. The first fixed plate 14 is provided with a stopper 452. The tape presser driver 41 drives and moves the connecting block 45, causing the position restricting piece 451 to move to the stopper 452, restricting the distance the connecting block 45 moves and further restricting the rotational width of the first connecting rod 43, preventing the first connecting rod 43 from colliding with the inner wall of the buffer box 10.

[0037] When the buffer device 100 is used, first, the transfer means moves the buffer box 10, buffer unit 20, moving unit 30, and tape pressure unit 40 to the location of the carrier tape 300 that needs to be buffered. Then, the movement driver 33 drives the first mounting plate 31 to move it relative to the second mounting plate 32, and moves the buffer box 10 to position the carrier tape 300 in the opening 101. At this time, the pressure bar 431 is located above the carrier tape 300 to assist and limit the movement position of the carrier tape 300. When the remaining carrier tape 300 needs to be buffered, the tape pressure driver 41 drives the mounting block 42 to move downward, and rotates the first connecting rod 43 in a direction away from the carrier tape 300, moving the pressure bar 431 away from the carrier tape 300 and moving the pressure wheel 421 so that it comes into contact with the carrier tape 300. The buffer movement driver 231 then drives the mounting block 232 to slide the second slide rail 232b, and moves the buffer driver 21, gear 22, and rotating holder 233 together, bringing the gear 22 closer to the carrier tape 300. At this time, the buffer driver 21 drives and rotates the gear 22, and the gear 221 of the gear 22 is positioned within the through-hole 301. The carrier tape 300 moves in tandem toward the first section 10a, enters the second section 10b from the first section 10a, and is finally buffered in the second section 10b. When buffering is complete, the buffer unit 20, the movement unit 30, and the tape pressure unit 40 are reset. At this time, external equipment processes the carrier tape 300 in the buffer box 10. The time it takes to process the carrier tape 300 in the buffer box 10 can be used to align the end of the carrier tape 300 with the beginning of the carrier tape 300 in another material tray 400.

[0038] In the buffer device 100, the gear 22 is driven and rotated by the buffer driver 21. Since the gear 221 of the gear 22 is provided in the through hole 301, the carrier tape 300 moves in tandem toward the buffer box 10. By buffering the carrier tape 300 in the buffer box 10, the time required to align the carrier tape 300 can be increased, improving alignment accuracy and eliminating the need to stop the equipment, thereby improving production efficiency.

[0039] Those skilled in the art should recognize that the above embodiments are provided to illustrate the present invention, and are not intended to limit the present invention. Any appropriate improvements and modifications to the above embodiments fall within the scope of the disclosure of this application, as long as they fall within the essential spirit of the present invention.
