Description

Technical Field

[0001] The present invention belongs to the technical field of SMT tape splicing, and particularly relates to a tape loading device and a tape splicing machine for a tape. Background Art

[0002] SMT (Surface Mount Technology) is the core technology in modern electronic manufacturing and is widely used in fields such as consumer electronics, communication equipment, and automotive electronics. The core equipment of the SMT chip mounting technology is the SMT mounter, which can automatically grab components and accurately place them on the PCB through an electronic eye identifier.

[0003] In the actual production process, when the tape in the mounter is about to run out, it is necessary to join the tape head of the new tape reel in the storage magazine and the tail of the old tape in the mounter through a tape splicing machine. This requires transporting the tape head of the new tape reel in the storage magazine to the splicing platform of the tape splicing machine. The existing transportation method usually adopts a double ratchet transportation method, where the first ratchet is installed on the storage magazine and the second ratchet is installed on the feeding frame. During operation, it is necessary for workers to first install the tape head of the new tape reel in the storage magazine on the first ratchet (i.e., the card hole on the tape head is stuck on the teeth of the first ratchet). The first ratchet rotates to send the tape head to the feeding platform of the feeding frame, and then the second ratchet transports the tape towards the splicing platform of the tape splicing machine. Obviously, the above method requires too much manual intervention and has the problem of low work efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a tape loading device and a tape splicing machine to solve the problem of low work efficiency in the conventional tape loading method in the prior art.

[0025] Further, a relief groove extending in the second direction is formed in a part of the bearing surface of the bearing groove corresponding to the relief gap. The relief groove is configured to relieve the teeth of the second conveying ratchet when the second conveying ratchet is inserted into the material clamping hole of the material head, so as to facilitate the teeth of the second conveying ratchet to be inserted into the material clamping hole of the material head.

[0026] Further, the feeding mechanism further includes a clamping assembly located at the loading station. The clamping assembly is configured to remove the limiting member from the bearing surface of the bearing groove after the material tape of the new material tray is conveyed.

[0028] Compared with the prior art, the beneficial effects of the material tape loading device are as follows:

[0029] 1) Through the cooperation of the conveying mechanism, the lifting mechanism and the feeding mechanism, the conveying mechanism receives the material tape magazine equipped with a new material tray and conveys the received material tape magazine to the lifting station. The lifting mechanism lifts the material tape magazine at the lifting station to a preset height, so that the material head in the bearing groove is at the loading station. At the same time, the second conveying ratchet is inserted into the bearing groove through the relief gap, so that the teeth of the second conveying ratchet are inserted into the material clamping hole of the material tape in the bearing groove. The first driving member drives the second conveying ratchet to rotate, conveys the material tape in the bearing groove to the feeding platform, and conveys the material tape on the feeding platform towards the receiving platform through the first conveying ratchet. The feeding of the material head of the new material tray can be realized without manual intervention, and the working efficiency is high.

[0030] 2) Through the cooperation of the first driving assembly, the second driving assembly, the first positioning portion and the second positioning portion, the first driving assembly drives the first positioning portion to lift and position on the bottom surface of the first limiting portion, and the second driving assembly drives the second positioning portion to descend and position on the top surface of the second limiting portion. The cooperation of the first positioning portion and the second positioning portion is used to internally support and position the material tape magazine, realizing a stable and reliable connection between the material tape magazine and the lifting member, and avoiding the position deviation and inclination of the material tape magazine during the lifting process driven by the lifting member, greatly improving the stability of the material tape magazine during lifting.

[0031] 3) By providing a positioning hole at the bottom of the first limiting block and arranging the positioning member at the top end of the positioning rod, when the lifting member moves to a preset height, the positioning member is inserted into the positioning hole and the end face of the second end of the positioning rod abuts against the bottom surface of the first limiting block, thereby realizing the positioning of the tape magazine in the first direction and the second direction, providing a positioning method with a simple positioning method and good positioning effect; at the same time, the second driving component drives the second positioning portion to descend, so that the V-shaped convex block fits and inserts into the V-shaped groove. By the mutual abutment of the V-shaped groove and the V-shaped convex block, it can not only cooperate with the first limiting block to limit the movement of the tape magazine in the horizontal direction and the height direction during the lifting process, but also limit the rotational movement of the tape magazine.

[0046] In a first aspect, a tape loading device is provided. Refer to Figures 1 to 11 As shown, in this embodiment, a tape loading device includes a base 10 and a conveying mechanism 20, a lifting mechanism 30 and a feeding mechanism 40 installed on the base 10. Among them: a lifting station is provided on the conveying path of the conveying mechanism 20. The conveying mechanism 20 is configured to receive a tape magazine 50 loaded with a new tape reel and convey the received tape magazine 50 along a first direction ( Figure 1 the X direction in Figure 1a relief gap 53 extending in the Y direction; the lifting mechanism 30 is arranged at the lifting station and on the first side of the conveying mechanism 20, and the lifting mechanism 30 is configured to lift the tape magazine 50 at the lifting station to a preset height so that the tape head in the carrying groove 51 is at the loading station; the feeding mechanism 40 includes a base 41, a first driving member 42, a first conveying ratchet 43, a second conveying ratchet 44 and a feeding platform 45. The base 41 is installed on the base table 10. The first conveying ratchet 43 and the second conveying ratchet 44 are rotatably installed on the base 41 and arranged at intervals along the second direction. The driving end of the first driving member 42 is connected to the first conveying ratchet 43 and the second conveying ratchet 44. The first driving member 42 is configured to drive the first conveying ratchet 43 and the second conveying ratchet 44 to rotate in the same direction. The feeding platform 45 is installed on the base table 10 and arranged below the first conveying ratchet 43. The second conveying ratchet 44 is located directly above the loading station. The feeding platform 45 is configured to receive the tape conveyed by the second conveying ratchet 44; the second conveying ratchet 44 is inserted into the carrying groove 51 through the relief gap 53 so that the teeth of the second conveying ratchet 44 are inserted into the card holes of the tape in the carrying groove 51. The first driving member 42 drives the second conveying ratchet 44 to rotate to convey the tape in the carrying groove 51 to the feeding platform 45, and the tape on the feeding platform 45 is conveyed towards the receiving platform through the first conveying ratchet 43.

[0047] Specifically, the conveying mechanism 20 adopts a linear module composed of a motor and a synchronous belt type linear transmission pair.

[0048] It can be seen that through the cooperation of the conveying mechanism 20, the lifting mechanism 30 and the feeding mechanism 40, the conveying mechanism 20 receives the tape magazine 50 loaded with a new reel and conveys the received tape magazine 50 to the lifting station. The lifting mechanism 30 lifts the tape magazine 50 at the lifting station to a preset height so that the tape head in the carrying groove 51 is at the loading station. At the same time, the second conveying ratchet 44 is inserted into the carrying groove 51 through the relief gap 53 so that the teeth of the second conveying ratchet 44 are inserted into the card holes of the tape in the carrying groove 51. The first driving member 42 drives the second conveying ratchet 44 to rotate, conveys the tape in the carrying groove 51 to the feeding platform 45, and conveys the tape on the feeding platform 45 towards the receiving platform through the first conveying ratchet 43, realizing the conveying of the tape head of the new reel without manual intervention and improving the working efficiency.

[0049] As an implementation manner, the lifting mechanism 30 includes a lifting frame 31, a first driving component 32, a second driving component 33, a lifting member 34, a first positioning portion 35 and a second positioning portion 36, wherein: The lifting frame 31 is vertically installed on the base 10. On one side of the tape magazine 50 close to the lifting frame 31, a first limiting portion 55 and a second limiting portion 56 are arranged along the height direction. The fixed end of the first driving component 32 is installed on the lifting frame 31, and the driving end of the first driving component 32 is connected to the lifting member 34. The first driving component is configured to drive the lifting member 34 to lift and lower. The first positioning portion 35 is fixed on the lifting member 34 and extends upward. The second driving component 33 is installed on the lifting member 34. The second positioning portion 36 extends downward and is connected to the driving end of the second driving component 33. The second driving component 33 is configured to drive the second positioning portion 36 to lift and lower. The first positioning portion 35 and the second positioning portion 36 are located between the first limiting portion 55 and the second limiting portion 56; The first driving component 32 drives the lifting member 34 to move to a first preset height, so that the first positioning portion 35 is lifted and positioned on the bottom surface of the first limiting portion 55. The second driving component 33 drives the second positioning portion 36 to descend, so that the second positioning portion 36 descends and is positioned on the top surface of the second limiting portion 56. Through the cooperation of the first positioning portion 35 and the second positioning portion 36, the tape magazine 50 is internally supported and positioned at the lifting station. The first driving component 32 drives the lifting member 34 to move to a second preset height, so that the tape head in the bearing groove 51 is at the feeding station.

[0050] Specifically, the first driving component 32 is an electric cylinder, and the lifting member 34 is a lifting seat. The driving end of the electric cylinder is connected to the lifting seat. The electric cylinder drives the lifting seat to rise to the first preset height, so that the positioning member 351 is inserted into the positioning hole 551 and the end surface of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550.

[0051] Certainly, as another implementation manner, the first driving component 32 can also be a driving motor, and the driving type of the first driving component 32 will not be elaborated here.

[0052] It can be seen that through the cooperation of the first driving component 32, the second driving component 33, the first positioning portion 35 and the second positioning portion 36, the first driving component 32 drives the first positioning portion 35 to be lifted and positioned on the bottom surface of the first limiting portion 55, and the second driving component 33 drives the second positioning portion 36 to descend and be positioned on the top surface of the second limiting portion 56. By using the cooperation of the first positioning portion 35 and the second positioning portion 36 to internally support and position the tape magazine 50, the stable and reliable connection between the tape magazine 50 and the lifting member 34 is realized, and the position deviation and inclination of the lifting member 34 during the process of driving the tape magazine 50 to lift and lower are avoided, greatly improving the stability of the tape magazine 50 during lifting.

[0053] As an implementation manner, the first limiting portion 55 includes a first limiting block 550 detachably mounted on the top end of the tape magazine 50. A positioning hole 551 is formed in the bottom surface of the first limiting block 550. The first positioning portion 35 includes a positioning rod 350 and a positioning member 351. The first end of the positioning rod 350 is mounted on the lifting member 34. The positioning member 351 is disposed at the second end of the positioning rod 350. The top end of the positioning member 351 is a conical surface with a smaller upper part and a larger lower part. The positioning member 351 is adapted to the positioning hole 551. When the lifting member 34 moves to the first preset height, the positioning member 351 is inserted into the positioning hole 551 and the end surface of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550. The second limiting portion 56 includes a second limiting block 560 detachably mounted on the bottom end of the tape magazine 50. A V-shaped groove 561 extending in the first direction is formed in the top surface of the second limiting block 560. The second positioning portion 36 includes a positioning block. A V-shaped protrusion 360 extending in the first direction is disposed on the bottom surface of the positioning block. The V-shaped protrusion 360 is adapted to the V-shaped groove 561. The second driving assembly 33 drives the second positioning portion 36 to descend, so that the V-shaped protrusion 360 is fitted and inserted into the corresponding V-shaped groove 561.

[0054] It can be seen that by forming the positioning hole 551 in the bottom of the first limiting block 550 and disposing the positioning member 351 at the top end of the positioning rod 350, when the lifting member 34 moves to the preset height, the positioning member 351 is inserted into the positioning hole 551 and the end surface of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550, the positioning of the tape magazine 50 in the first direction and the second direction is realized, providing a positioning method with a simple positioning method and a good positioning effect. At the same time, the second driving assembly 33 drives the second positioning portion 36 to descend, so that the V-shaped protrusion 360 is fitted and inserted into the V-shaped groove 561. By the mutual abutment of the V-shaped groove 561 and the V-shaped protrusion 360, not only can the movement of the tape magazine 50 in the horizontal direction and the height direction be restricted during the lifting process in cooperation with the first limiting block 550, but also the rotational movement of the tape magazine 50 can be restricted.

[0055] Specifically, the second driving assembly 33 is a double-rod cylinder. The fixed end of the double-rod cylinder is mounted on the lifting member 34. The driving end of the double-rod cylinder is connected to the upper end of the positioning block. The double-rod cylinder drives the positioning block to descend until the V-shaped protrusion 360 is fitted and inserted into the corresponding V-shaped groove 561.

[0056] It can be seen that by using the second driving assembly 33 as a double-rod cylinder, the two piston rods of the double-rod cylinder are symmetrically distributed and connected by a mounting rod, avoiding the torque caused by unilateral force, preventing the deflection or self-rotation of a single piston rod. The upper end of the positioning block is connected to the two piston rods, further avoiding the phenomenon of the positioning block rotating during the lifting process.

[0057] As an implementation manner, the first driving member 42 includes a first motor 420, a driving gear 421, a first intermediate gear 422, a second intermediate gear 423, a first driven gear 424 and a second driven gear 425, wherein: the fixed end of the first motor 420 is mounted on the base 41, the driving gear 421 is rotatably mounted on the base 41, the driving end of the first motor 420 is connected to the driving gear 421, and the first motor 420 is configured to drive the driving gear 421 to rotate; the first driven gear 424 and the second driven gear 425 are rotatably mounted on the base 41 and located on one side of the driving gear 421 in the second direction, the first intermediate gear 422 is rotatably mounted on the base 41 and located between the driving gear 421 and the first driven gear 424, and the second intermediate gear 423 is rotatably mounted on the base 41 and located between the first driven gear 424 and the second driven gear 425; the driving gear 421 is coaxially and drivingly connected to the first conveying ratchet wheel 43, the second driven gear 425 is coaxially and drivingly connected to the second conveying ratchet wheel 44, the driving gear 421 meshes with the first intermediate gear 422, the first driven gear 424 meshes with the first intermediate gear 422 and the second intermediate gear 423, and the second driven gear 425 meshes with the second intermediate gear 423; the first motor 420 drives the driving gear 421 to rotate, so as to synchronously drive the first driven gear 424 to rotate in the same direction through the first intermediate gear 422, and then the first driven gear 424 rotating in the same direction synchronously drives the second driven gear 425 to rotate in the same direction through the second intermediate gear 423, thereby driving the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 to rotate synchronously in the same direction.

[0058] It can be seen that through the cooperation of the first motor 420, the driving gear 421, the first intermediate gear 422, the second intermediate gear 423, the first driven gear 424 and the second driven gear 425, a driving assembly with a compact structure, stable operation and high transmission efficiency is provided, ensuring the accuracy and stability of the feeding head conveying;

[0059] Specifically, the driving gear 421 and the second driven gear 425 have the same specifications, the first intermediate gear 422 and the second intermediate gear 423 have the same specifications, the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 have the same specifications, and the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 have the same installation height.

[0060] It can be seen that by setting the same specifications for the intermediate gears, the same specifications for the driving gear 421 and the second driven gear 425, and the same specifications for the conveying ratchet wheels, the conveying speed of the feeding head on the tape magazine 50 by the first motor 420 is made consistent with the conveying speed of the feeding head on the feeding platform 45, ensuring the safety and stability of the feeding head conveying.

[0061] As an implementation manner, the feeding mechanism 40 further includes a feeding frame 46 and a second driving member. The feeding frame 46 is vertically installed on the base 10. The second driving member includes a second motor 47, a third motor 48, a transverse movement seat 49, and a lifting seat 400, where: the transverse movement seat 49 is arranged on the top of the feeding frame 46 so as to reciprocate along a first direction, the lifting seat 400 is arranged on the transverse movement seat 49 so as to be liftable, the fixed end of the third motor 48 is installed on the transverse movement seat 49, the driving end of the third motor 48 is connected to the lifting seat 400, and the third motor 48 is configured to drive the lifting seat 400 to lift so as to drive the base 41 to lift. The fixed end of the second motor 47 is installed on the feeding frame 46, the driving end of the second motor 47 is connected to the transverse movement seat 49, and the second motor 47 is configured to drive the transverse movement seat 49 to traverse along the first direction.

[0062] Specifically, the second driving member adopts a linear module composed of a motor cooperating with a synchronous belt linear transmission pair and a ball screw linear transmission pair.

[0063] It can be seen that through the cooperation of the second motor 47, the third motor 48, the transverse movement seat 49, and the lifting seat 400, the transverse movement and lifting of the base 41 are realized, and the upper space of the feeding platform 45 can be avoided during subsequent processes, which is convenient for subsequent operations.

[0064] As an implementation manner, the base 41 is installed on the lifting seat 400 through a floating assembly 60. The floating assembly 60 includes a floating plate 61 and at least one buffer member 62. The first end of each buffer member 62 is connected to the lifting seat 400, the second end of each buffer member 62 is connected to the top end of the floating plate 61, and the base 41 is installed on the floating plate 61.

[0065] Specifically, two buffer members 62 are provided, and both buffer members 62 are buffer springs, and the two buffer springs are arranged at intervals along a second direction.

[0066] It can be seen that by providing the floating assembly 60, the floating connection between the base 41 and the lifting seat 400 is realized, and the phenomenon that the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 on the base 41 are in hard contact with the feeding platform 45 is avoided.

[0067] Specifically, a mounting seat 410 is fixedly arranged on the base 41. The mounting seat 410 has a receiving cavity. The first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 are located in the receiving cavity, and the bottom ends of the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 extend out of the receiving cavity.

[0068] Specifically, the driving gear 421, the first intermediate gear 422, the second intermediate gear 423, the first driven gear 424, and the second driven gear 425 are located in the receiving cavity.

[0069] It can be seen that by providing the mounting base 410 with a receiving cavity and arranging the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 in the receiving cavity, the first conveying ratchet wheel 43 and the second conveying ratchet wheel 44 are protected, avoiding the risk of tape winding during the tape conveying process, and improving the safety and reliability of the tape conveying process.

[0070] Specifically, at least two rotatable limiting wheels 411 are arranged at intervals along the second direction at the bottom of the mounting base 410. The at least two limiting wheels 411 are located directly above the feeding platform 45, and the at least two limiting wheels 411 are configured to limit the tape on the feeding platform 45 in the vertical direction.

[0071] Specifically, two rotatable limiting wheels 411 are arranged at intervals along the second direction at the bottom of the mounting base 410. The two limiting wheels 411 are located directly above the feeding platform 45.

[0072] Of course, as another implementation manner, the limiting wheel 411 can be directly arranged on the base 41.

[0073] It can be seen that by arranging the rotatable limiting wheels 411 at intervals along the second direction at the bottom of the mounting base 410, the tape head on the feeding platform 45 is limited in the vertical direction. While preventing the tape head from shifting or jumping during the conveying process, the friction with the upper surface of the tape head is reduced, ensuring the smoothness and stability of the tape head transporting along the second direction.

[0074] As an implementation manner, a positioning groove 510 is provided on one side of the bearing groove 51 in the second direction. A positioning protrusion 520 is provided on the bottom surface of the limiting member 52. The positioning protrusion 520 is adapted to the positioning groove 510. When the limiting member 52 is placed on the bearing surface of the bearing groove 51, the positioning protrusion 520 fits and inserts into the positioning groove 510.

[0075] Specifically, the positioning groove 510 is a rectangular groove, and the positioning protrusion 520 is a rectangular protrusion adapted to the rectangular groove.

[0076] It can be seen that by adopting the positioning structure in which the positioning protrusion 520 and the positioning groove 510 cooperate with each other, it is ensured that the limiting member 52 can be accurately placed at the preset position on the bearing groove 51.

[0077] As an implementation manner, an avoidance groove 511 extending along the second direction is provided on the bearing surface of the bearing groove 51 corresponding to the avoidance gap 53. The avoidance groove 511 is configured to avoid the teeth of the second conveying ratchet wheel 44 when the second conveying ratchet wheel 44 is inserted into the material clamping hole of the tape head, so as to facilitate the teeth of the second conveying ratchet wheel 44 to be inserted into the material clamping hole of the tape head.

[0078] As an implementation manner, the feeding mechanism further includes a clamping assembly 460. The clamping assembly 460 is installed on the lifting frame 400 and is located at the loading station. The clamping assembly 460 is configured to move the limiting member 52 away from the bearing surface of the bearing groove 51 after the tape of the new tape reel is conveyed.

[0079] Specifically, the clamping assembly adopts an electric gripper.

[0080] It can be seen that by setting the clamping assembly 460, the limiting member 52 is moved away from the bearing surface of the bearing groove 51 after the tape of the new tape reel is conveyed, which facilitates the subsequent replacement of the new tape reel by manual or robotic means.

[0081] In a second aspect, a tape loading machine is provided, which includes the above-mentioned tape loading device.

[0082] When the above-mentioned tape loading device is working, the following steps are carried out:

[0083] S1, Place a plurality of tape cartridges 50 containing new tape reels on the conveying mechanism 20 in sequence. The conveying mechanism 20 drives the tape cartridges 50 to move along the first direction, driving the tape cartridges 50 containing new tape reels to move to the jacking station in sequence;

[0084] S2, The first driving assembly 32 located at the jacking station drives the lifting member 34 to move to the first preset height, so that the first positioning portion 35 jacks up and is positioned on the bottom surface of the first limiting portion 55. The second driving assembly 33 drives the second positioning portion 36 to descend, so that the second positioning portion 36 descends and is positioned on the top surface of the second limiting portion 56, and the tape cartridge 50 is internally supported and positioned. After the positioning is completed, the first driving assembly 32 drives the lifting member 34 to move to the second preset height, so that the tape head in the bearing groove 51 is at the loading station;

[0085] S4, The second driving member drives the base 41 to horizontally move and lift towards the feeding platform 45, so that the teeth of the feeding ratchet are inserted into the card holes of the tape in the bearing groove 51;

[0086] S5, The first driving member 42 drives the second conveying ratchet 44 to rotate, conveys the tape in the bearing groove 51 to the feeding platform 45, and conveys the tape on the feeding platform 45 towards the receiving platform through the first conveying ratchet 43.

[0087] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above examples. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
