Description

Technical Field

[0001] This utility model belongs to the field of SMT tape splicing technology, and in particular relates to a tape feeding device and a tape splicing machine. Background Technology

[0002] SMT (Surface Mount Technology) is a core technology in modern electronics manufacturing and is widely used in consumer electronics, communication equipment, automotive electronics and other fields. The core equipment of SMT technology is the SMT placement machine, which can automatically pick up components and place them accurately on the PCB through an electronic eye recognition device.

[0003] In actual production, when the tape in the pick-and-place machine is about to run out, a tape receiver is needed to connect the tape head of the new tape tray in the storage cartridge to the tail of the old tape in the pick-and-place machine. This requires conveying the tape head of the new tape tray in the storage cartridge to the receiving platform of the tape receiver. Existing conveying methods typically use a double ratchet system, where the first ratchet is mounted on the storage cartridge and the second ratchet is mounted on the feeder frame. During operation, the tape head of the new tape tray in the storage cartridge must first be manually mounted onto the first ratchet (i.e., the clip on the tape head engages with the teeth of the first ratchet). The first ratchet rotates, conveying the tape head to the feeding platform of the feeder frame. Then, the second ratchet conveys the tape towards the receiving platform of the tape receiver. Clearly, this method requires excessive manual intervention and suffers from low work efficiency. Utility Model Content

The avoidance groove is configured to avoid the teeth of the second conveying ratchet when the second conveying ratchet is engaged in the material clamping hole of the material belt head, so that the teeth of the second conveying ratchet can be engaged in the material clamping hole of the material belt head.

[0026] Furthermore, the feeding mechanism also includes a clamping assembly located at the loading station, which is configured to remove the limiting member from the bearing surface of the bearing groove after the material belt of the new material tray has been conveyed.

[0027] Secondly, a material strip feeding machine is provided, which includes the aforementioned material strip feeding device.

[0028] Compared with the prior art, the advantages of the material belt feeding 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 strip clips containing new material trays and transports the received material strip clips to the lifting station. The lifting mechanism lifts the material strip clips in the lifting station to a preset height, so that the material strip head in the bearing groove is in the loading station. At the same time, the second conveying ratchet is inserted into the bearing groove through the clearance gap, so that the teeth of the second conveying ratchet are inserted into the material clamping hole of the material strip in the bearing groove. The first driving component drives the second conveying ratchet to rotate, sending the material strip in the bearing groove to the feeding platform. The first conveying ratchet then transports the material strip on the feeding platform toward the receiving platform. The material strip head of the new material tray can be transported without manual intervention, resulting in high work efficiency.

[0030] 2) Through the cooperation of the first drive assembly, the second drive assembly, the first positioning part and the second positioning part, the first drive assembly drives the first positioning part to rise and position on the bottom surface of the first limiting part, and the second drive assembly drives the second positioning part to fall and position on the top surface of the second limiting part. The cooperation of the first positioning part and the second positioning part implements internal support and positioning for the material strip clip, realizing a stable and reliable connection between the material strip clip and the lifting component, avoiding positional shift and tilting of the lifting component during the lifting and lowering of the material strip clip, and greatly improving the stability of the material strip clip during lifting and lowering.

[0031] 3) By opening a positioning hole at the bottom of the first limiting block and setting the positioning component at the top of the positioning rod, when the lifting component moves to the preset height, the positioning component 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, thus realizing the positioning of the material strip clip in the first and second directions, providing a simple and effective positioning method; at the same time, the second driving component drives the second positioning part to descend, so that the V-shaped protrusion fits into the V-shaped groove. Through the mutual abutment between the V-shaped groove and the V-shaped protrusion, it can not only cooperate with the first limiting block to restrict the movement of the material strip clip in the horizontal and vertical directions during the lifting process, but also restrict the rotational movement of the material strip clip.

[0046] Firstly, a material belt feeding device is provided; please refer to [reference needed]. Figures 1 to 11 As shown, in this embodiment, a material conveying device includes a base 10 and a conveying mechanism 20, a lifting mechanism 30, and a feeding mechanism 40 mounted on the base 10. The conveying mechanism 20 has a lifting station along its conveying path. The conveying mechanism 20 is configured to receive a material conveyor clip 50 containing a new material tray and to move the received material conveyor clip 50 along a first direction (…). Figure 1 The material is conveyed to the lifting station in the X direction. A carrying groove 51 and a limiting member 52 are provided at the top of one end of the material clip 50 near the first side of the conveying mechanism 20. The carrying groove 51 is configured to carry the head of the new material tray, and the limiting member 52 is configured to press the head of the material in the carrying groove 51 onto the carrying surface of the carrying groove 51. The limiting member 52 and the carrying groove 51 are positioned along a second direction (X direction). Figure 1The avoidance gap 53 extends in the Y direction; the lifting mechanism 30 is set at the lifting station and located on the first side of the conveying mechanism 20. The lifting mechanism 30 is configured to lift the material strip clip 50 at the lifting station to a preset height so that the material strip head in the bearing groove 51 is in 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 mounted on the base 10. The first conveying ratchet 43 and the second conveying ratchet 44 are rotatably mounted on the base 41 and spaced apart 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 actuator 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 mounted on the base 10 and located 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 material belt conveyed by the second conveying ratchet 44. The second conveying ratchet 44 is inserted into the bearing groove 51 through the clearance gap 53, so that the teeth of the second conveying ratchet 44 are inserted into the material clamping holes of the material belt in the bearing groove 51. The first driving member 42 drives the second conveying ratchet 44 to rotate, so as to send the material belt in the bearing groove 51 to the feeding platform 45. The first conveying ratchet 43 conveys the material belt on the feeding platform 45 toward the receiving platform.

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

[0048] As can be seen, through the cooperation of the conveying mechanism 20, the lifting mechanism 30 and the feeding mechanism 40, the conveying mechanism 20 receives the material strip clip 50 containing the new material tray and conveys the received material strip clip 50 to the lifting position. The lifting mechanism 30 lifts the material strip clip 50 in the lifting position to a preset height, so that the material strip head in the bearing groove 51 is in the loading position. At the same time, the second conveying ratchet 44 is inserted into the bearing groove 51 through the clearance gap 53, so that the teeth of the second conveying ratchet 44 are inserted into the material clamping hole of the material strip in the bearing groove 51. The first driving member 42 drives the second conveying ratchet 44 to rotate, sending the material strip in the bearing groove 51 to the feeding platform 45. The first conveying ratchet 43 then conveys the material strip on the feeding platform 45 toward the receiving platform. The material strip head of the new material tray can be conveyed without manual intervention, which improves work efficiency.

[0049] In one embodiment, the lifting mechanism 30 includes a lifting frame 31, a first drive assembly 32, a second drive assembly 33, a lifting member 34, a first positioning part 35, and a second positioning part 36. The lifting frame 31 is vertically mounted on the base 10. The feed belt clip 50 has a first limiting part 55 and a second limiting part 56 along its height direction on the side near the lifting frame 31. The fixed end of the first drive assembly 32 is mounted on the lifting frame 31, and the driving end of the first drive assembly 32 is connected to the lifting member 34. The first drive assembly is configured to drive the lifting member 34 to move up and down. The first positioning part 35 is fixed to the lifting member 34 and extends upwards. The second drive assembly 33 is mounted on the lifting member 34, and the second positioning part 36 extends downwards and is connected to the second drive assembly 33. At the driving end, the second driving component 33 is configured to drive the second positioning part 36 to rise and fall. The first positioning part 35 and the second positioning part 36 are located between the first limiting part 55 and the second limiting part 56. The first driving component 32 drives the lifting member 34 to move to the first preset height so that the first positioning part 35 is lifted and positioned on the bottom surface of the first limiting part 55. The second driving component 33 drives the second positioning part 36 to fall so that the second positioning part 36 falls and is positioned on the top surface of the second limiting part 56. Through the cooperation of the first positioning part 35 and the second positioning part 36, the material strip clip 50 is internally supported and positioned at the lifting station. The first driving component 32 drives the lifting member 34 to move to the second preset height so that the material strip head in the bearing groove 51 is in the loading station.

[0050] Specifically, the first drive component 32 is an electric cylinder, the lifting component 34 is a lifting seat, the drive 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 component 351 is inserted into the positioning hole 551 and the end face of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550.

[0051] Of course, as another implementation, the first drive component 32 can also be a drive motor, and the drive type of the first drive component 32 will not be described in detail here.

[0052] As can be seen, through the cooperation of the first drive assembly 32, the second drive assembly 33, the first positioning part 35, and the second positioning part 36, the first drive assembly 32 drives the first positioning part 35 to rise and be positioned on the bottom surface of the first limiting part 55, and the second drive assembly 33 drives the second positioning part 36 to fall and be positioned on the top surface of the second limiting part 56. The cooperation of the first positioning part 35 and the second positioning part 36 provides internal support and positioning for the material strip clip 50, thereby achieving a stable and reliable connection between the material strip clip 50 and the lifting component 34. This avoids positional shift and tilting of the lifting component 34 during the lifting and lowering of the material strip clip 50, and greatly improves the stability of the material strip clip 50 during lifting and lowering.

[0053] In one embodiment, the first limiting part 55 includes a first limiting block 550 detachably mounted on the top of the feed strip clip 50. The bottom surface of the first limiting block 550 has a positioning hole 551. The first positioning part 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, and the positioning member 351 is disposed at the second end of the positioning rod 350. The top of the positioning member 351 is a conical surface that is smaller at the top and larger at the bottom. 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. The end face of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550; the second limiting part 56 includes a second limiting block 560 detachably installed at the bottom end of the material belt clip 50, and a V-shaped groove 561 extending in the first direction is provided on the top surface of the second limiting block 560. The second positioning part 36 includes a positioning block, and a V-shaped protrusion 360 extending in the first direction is provided on the bottom surface of the positioning block. The V-shaped protrusion 360 is adapted to the V-shaped groove 561. The second driving component 33 drives the second positioning part 36 to descend, so that the V-shaped protrusion 360 fits into the corresponding V-shaped groove 561.

[0054] As can be seen, by opening a positioning hole 551 at the bottom of the first limiting block 550 and setting the positioning member 351 at the top 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 face of the second end of the positioning rod 350 abuts against the bottom surface of the first limiting block 550, the positioning of the material strip clip 50 in the first direction and the second direction is realized, providing a positioning method that is simple and has a good positioning effect; at the same time, the second driving component 33 drives the second positioning part 36 to descend, so that the V-shaped protrusion 360 fits into the V-shaped groove 561. Through the mutual abutment between the V-shaped groove 561 and the V-shaped protrusion 360, it can not only cooperate with the first limiting block 550 to restrict the movement of the material strip clip 50 in the horizontal and vertical directions during the lifting process, but also restrict the rotational movement of the material strip clip 50.

[0055] Specifically, the second drive component 33 is a double-rod cylinder. The fixed end of the double-rod cylinder is installed on the lifting component 34, and the drive 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 fits and inserts into the corresponding V-shaped groove 561.

[0056] As can be seen, by using a double-rod cylinder as the second drive component 33, the two piston rods of the double-rod cylinder are symmetrically distributed and connected by a mounting rod, the torque caused by unilateral force is avoided, and the deflection or spin of a single piston rod is prevented. 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] In one embodiment, 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 a 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. 1. Located between the first driven gear 424 and the second driven gear 425; the driving gear 421 is coaxially connected to the first conveying ratchet 43, the second driven gear 425 is coaxially connected to the second conveying ratchet 44, the driving gear 421 meshes with the first transition gear 422, the first driven gear 424 meshes with the first transition gear 422 and the second transition gear 423, and the second driven gear 425 meshes with the second transition 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 transition 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 transition gear 423, thereby driving the first conveying ratchet 43 and the second conveying ratchet 44 to rotate synchronously in the same direction.

[0058] As can be seen, the combination of the first motor 420, the driving gear 421, the first transition gear 422, the second transition gear 423, the first driven gear 424 and the second driven gear 425 provides a drive assembly with a compact structure, stable operation and high transmission efficiency, ensuring the accuracy and stability of the material head conveying.

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

[0060] It can be seen that by setting the transition gears to have the same specifications, the driving gear 421 and the second driven gear 425 to have the same specifications, and the conveying ratchet to have the same specifications, the conveying speed of the first motor 420 on the material belt clip 50 and the conveying speed of the material head on the feeding platform 45 are consistent, thus ensuring the safety and stability of the material head conveying.

[0061] In one embodiment, the feeding mechanism 40 further includes a feeding frame 46 and a second driving member. The feeding frame 46 is vertically mounted on the base 10. The second driving member includes a second motor 47, a third motor 48, a transverse shift seat 49, and a lifting seat 400. The transverse shift seat 49 is reciprocally movable on the top of the feeding frame 46 in a first direction. The lifting seat 400 is vertically movable on the transverse shift seat 49. The fixed end of the third motor 48 is mounted on the transverse shift seat 49, and the driving end of the third motor 48 is connected to the lifting seat 400. The third motor 48 is configured to drive the lifting seat 400 to rise and fall, thereby driving the base 41 to rise and fall. The fixed end of the second motor 47 is mounted on the feeding frame 46, and the driving end of the second motor 47 is connected to the transverse shift seat 49. The second motor 47 is configured to drive the transverse shift seat 49 to move laterally in the first direction.

[0062] Specifically, the second drive unit is a linear module consisting of a motor, a synchronous belt linear transmission pair, and a ball screw linear transmission pair.

[0063] As can be seen, the cooperation of the second motor 47, the third motor 48, the transverse moving seat 49 and the lifting seat 400 realizes the transverse movement and lifting of the drive base 41, which can avoid the upper space of the feeding platform 45 when performing subsequent processes, thus facilitating subsequent operations.

[0064] In one embodiment, the base 41 is mounted on the lifting seat 400 via 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, and the second end of each buffer member 62 is connected to the top end of the floating plate 61. The base 41 is mounted on the floating plate 61.

[0065] Specifically, there are two buffer elements 62, both of which are buffer springs, and the two buffer springs are spaced apart along the second direction.

[0066] As can be seen, by setting the floating component 60, a floating connection between the base 41 and the lifting seat 400 is achieved, avoiding the phenomenon of hard contact between the first conveying ratchet 43 and the second conveying ratchet 44 on the base 41 and the feeding platform 45.

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

[0068] Specifically, the driving gear 421, the first transition gear 422, the second transition gear 423, the first driven gear 424, and the second driven gear 425 are located within the accommodating cavity.

[0069] As can be seen, by setting a mounting base 410 with a accommodating cavity and placing the first conveying ratchet 43 and the second conveying ratchet 44 inside the accommodating cavity, the first conveying ratchet 43 and the second conveying ratchet 44 are protected, avoiding the risk of the material belt getting tangled during the conveying process, and improving the safety and reliability of the material belt conveying process.

[0070] Specifically, at least two rotatable limiting wheels 411 are provided 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 are configured to limit the material belt on the feeding platform 45 in the vertical direction.

[0071] Specifically, the bottom of the mounting base 410 is provided with two rotatable limit wheels 411 at intervals along the second direction, and the two limit wheels 411 are located directly above the feeding platform 45.

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

[0073] As can be seen, by setting rotatable limiting wheels 411 at intervals along the second direction at the bottom of the mounting base 410, the material head on the feeding platform 45 is vertically limited, preventing the material head from deviating or jumping during the conveying process, while reducing the friction between the material head and the surface of the material head, thus ensuring the smoothness and stability of the material head's transport along the second direction.

[0074] In one embodiment, the bearing groove 51 has a positioning groove 510 on one side in the second direction, and the bottom surface of the limiting member 52 has a positioning protrusion 520. 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 into the positioning groove 510.

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

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

[0077] In one embodiment, a relief groove 511 extending in the second direction is provided on the bearing surface of the bearing groove 51 corresponding to the relief gap 53. The relief groove 511 is configured to avoid the teeth of the second conveying ratchet 44 when the second conveying ratchet 44 is inserted into the material clamping hole of the material head, so that the teeth of the second conveying ratchet 44 can be inserted into the material clamping hole of the material head.

[0078] In one embodiment, the feeding mechanism also includes a clamping assembly 460, which is mounted on the lifting frame 400 and located at the loading station. The clamping assembly 460 is configured to remove the limiting member 52 from the bearing surface of the bearing groove 51 after the material belt of the new material tray has been conveyed.

[0079] Specifically, the clamping assembly uses electric grippers.

[0080] As can be seen, by setting the clamping component 460, the limiting component 52 can be removed from the bearing surface of the bearing groove 51 after the material belt of the new material tray is conveyed, which facilitates the replacement of the new material tray by manual or robotic arm.

[0081] Secondly, a material strip feeding machine is provided, which includes the aforementioned material strip feeding device.

[0082] The above-mentioned conveyor belt feeding device performs the following steps during operation:

[0083] S1, several tape clips 50 with new material trays are placed on the conveying mechanism 20 in sequence. The conveying mechanism 20 drives the tape clips 50 to move along the first direction, and drives the tape clips 50 with new material trays to move to the lifting position in sequence.

[0084] S2, the first drive assembly 32 located at the lifting station drives the lifting member 34 to move to the first preset height, so that the first positioning part 35 is lifted and positioned on the bottom surface of the first limiting part 55. The second drive assembly 33 drives the second positioning part 36 to descend, so that the second positioning part 36 descends and is positioned on the top surface of the second limiting part 56, and performs internal support positioning on the material strip clip 50. After positioning is completed, the first drive assembly 32 drives the lifting member 34 to move to the second preset height, so that the material strip head in the bearing groove 51 is in the loading station.

[0085] S4, the second drive unit drives the base 41 to move laterally and rise and fall toward the feeding platform 45, so that the teeth of the feeding ratchet are inserted into the material clamping hole of the material belt in the bearing groove 51.

[0086] S5, the first driving member 42 drives the second conveying ratchet 44 to rotate, and sends the material belt in the bearing groove 51 to the feeding platform 45. The material belt on the feeding platform 45 is then conveyed toward the receiving platform by the first conveying ratchet 43.

[0087] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
