[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Research has found that in the patch process, a material tape is needed. The material tape is set on a reel and continuously pulled out until it is used up and then replaced. In order to improve the operating efficiency of the production line, a specially designed tape changing mechanism is required to replace the new material tape on the reel during the continuous conveying of the material tape.

[0027] However, in order to install the material tape on the reel, the end of the material tape will be bent to fit into the groove of the reel. But after the end of the material tape is pulled out, a crease will be formed. During the process of changing the tape without stopping the machine, the crease will not be eliminated, which will affect the use of this section of the material tape.

[0028] Based on the above research, Figure 1 The embodiment of the present disclosure provides a docking bin device for SMT feeding, comprising: a docking bin body 1, a belt extraction mechanism 2 and a control module, wherein the belt extraction mechanism 2 is suitable for extracting the tape from the old reel, and the docking bin body 1 is suitable for temporarily storing the tape extracted by the belt extraction mechanism 2. Specifically, referring to Figure 4 The docking bin body 1 has an opening 10 at the top, which is suitable for allowing the material tape to enter the docking bin body 1 for temporary storage, and the docking bin body 1 has a conveying track 11 at the top, and when the material tape is replaced, the material tape is transported along the conveying track 11. The belt-drawing mechanism 2 is slidably arranged on one side of the docking bin body 1, and the belt-drawing mechanism 2 has a belt-changing assembly 3 on the side facing the conveying track 11. The control module is communicatively connected with the belt-drawing mechanism 2 and the belt-changing assembly 3, and is suitable for controlling the lifting and lowering of the belt-drawing mechanism 2.

[0029] Reference Figure 2 In order to achieve the effect of replacing the material belt, the belt changing assembly 3 includes a belt drawing wheel 31 and a belt feeding wheel 32 arranged in sequence along the material belt conveying direction. The belt drawing wheel 31 and the belt feeding wheel 32 are both facing the opening 10, but the rotation speed of the belt drawing wheel 31 is faster than that of the belt feeding wheel 32. When replacing the material belt, the belt drawing mechanism 2 descends, so that the belt drawing wheel 31 and the belt feeding wheel 32 respectively push the material belt down, insert the conveying track 11 and press the material belt, and then the belt drawing wheel 31 and the belt feeding wheel 32 rotate. Since the rotation speed of the belt drawing wheel 31 is faster than that of the belt feeding wheel 32, the length of the material belt drawn out by the belt drawing wheel 31 is greater than the length of the material belt delivered by the belt feeding wheel 32. The material belt drawn out by the belt drawing wheel 31 and not delivered by the belt feeding wheel 32 will fall into the inside of the docking bin body 1 through the opening 10, and the belt feeding wheel 32 will deliver the material belt in the docking bin body 1. The arrangement of the above-mentioned components allows the remaining unconveyed material on the reel to be drawn out by the withdrawal wheel 31 while maintaining conveyance, and temporarily stored inside the docking bin body 1 for subsequent conveyance by the delivery wheel 32, thereby avoiding interruption of the material tape due to the inability to continuously convey the material tape when replenishing the reel of the material tape.

[0030] Reference Figure 2In order to eliminate the fold at the end of the material belt, in at least one embodiment, the interior of the belt pulley 31 is hollow, and a plurality of air extraction grooves 33 are provided around the belt pulley 31, and the air extraction grooves 33 are densely arranged along the circumference of the belt pulley 31. When the belt pulley 31 extracts air through the air extraction grooves 33, the material belt pressed by the belt pulley 31 will be tightly adsorbed on the air extraction grooves 33, and further attached to the rotating wheel of the belt pulley 31. In addition, since the air extraction grooves 33 are densely arranged around the circumference of the belt pulley 31, the problem of being unable to adsorb the material belt due to the large interval between different air extraction grooves 33 is effectively avoided. Further, a rotary joint 34 is installed on one side of the belt pulley 31, and the rotary joint 34 can be connected to an air extraction device such as an air pump through an air pipe, thereby realizing the air extraction function of the air extraction groove 33, and the rotary joint 34 also realizes the effect that the air extraction device will not be driven to rotate together when the belt pulley 31 rotates, thereby avoiding the influence of the rotation of the belt pulley 31 on the air extraction device.

[0031] Reference Figure 2 The following specifically describes how to eliminate the crease at the end of the material belt. When the withdrawal wheel 31 rotates and presses over the crease of the material belt, that is, the very end of the material belt, the crease will be flattened. At this time, the vacuum device is started, and the end of the material belt is tightly adsorbed on the rotating wheel of the withdrawal wheel 31. At the same time, the withdrawal wheel 31 rotates in the opposite direction, and the material belt is drawn out from the inside of the docking bin body 1 in the opposite direction, and is rolled up and bent on the withdrawal wheel 31, and the crease of the material belt is bent in the opposite direction to offset the angle caused by the crease. Then the withdrawal wheel 31 restores its original rotation direction and stops vacuuming. The withdrawal wheel 31 draws out the remaining material belt, presses the crease for the last time to eliminate it, and then the remaining material belt is sent into the docking bin body 1. It should be explained in detail that in order to achieve the best effect of eliminating creases, when the material belt is transported horizontally, the protruding direction of the crease is upward. In this way, when the material belt is rolled onto the withdrawal wheel 31, the protruding direction of the crease is toward the withdrawal wheel 31. When rolling, the crease will be bent in the opposite direction of its protrusion, which has the best effect of eliminating the crease. It is also worth mentioning that there is a guide 35 between the withdrawal wheel 31 and the feeding wheel 32. The lower part of the guide 35 protrudes from the bottom of the withdrawal wheel 31 and the feeding wheel 32, and is used to guide the material belt drawn out by the withdrawal wheel 31 into the interior of the docking bin body 1. The belt changing assembly 3 also includes two belt pressing plates 36, which are horizontally arranged and respectively located on both sides of the withdrawal wheel 31, and are used to assist the withdrawal wheel 31 and the feeding wheel 32 to press the material belt after the withdrawal mechanism 2 slides downward.

[0032] Reference Figure 1 and Figure 3In at least one embodiment, an adjustment motor 12 is installed on one side of the docking bin body 1, and an adjustment shaft 13 is installed on the movable end of the adjustment motor 12. The adjustment shaft 13 is provided with a limit rod 14 and a limit plate 15 at intervals. The falling material belt falls along the limit rod 14, then contacts the limit plate 15, is limited by the limit rod 14 and the limit plate 15, and falls on the adjustment shaft 13 between the limit rod 14 and the limit plate 15, so as to avoid damage to the material belt due to excessive falling angle when the material belt falls. It is worth mentioning that the adjustment motor 12 can freely adjust the height of the adjustment shaft 13 to timely adjust the falling angle of the material belt.

[0033] Reference Figure 5 In order to achieve the effect of the belt-drawing mechanism 2 sliding up and down, in at least one embodiment, a bracket 4 is provided on one side of the docking bin body 1, and a lifting rail 41 is provided on the bracket 4. When the belt-drawing mechanism 2 slides up and down, it slides along the lifting rail 41. A driving motor 411 is installed on the bracket 4, and a screw rod is installed on the movable end of the driving motor 411. The belt-drawing mechanism 2 includes a belt-drawing seat 42, and the belt-drawing seat 42 is slidably arranged on the lifting rail 41 and is threadedly connected to the screw rod. When the driving motor 411 drives the screw rod to rotate, the belt-drawing seat 42 threadedly connected to the screw rod is further driven to slide along the lifting rail 41, thereby achieving the effect of the belt-drawing mechanism 2 sliding up and down. It is also worth mentioning that the belt-drawing seat 42 is provided with a translation rail 43, and a translation seat 44 is slidably arranged on the translation rail 43, and the translation seat 44 is suitable for sliding along the translation rail 43. The belt-drawing seat 42 is also provided with a translation motor, a screw is installed at the movable end of the translation motor, and the translation seat 44 is threadedly connected to the screw. The translation motor can drive the screw to rotate, and further drive the translation seat 44 to slide along the translation rail 43. The belt-drawing wheel 31 and the belt-feeding wheel 32 are both installed on the translation seat 44, so that the belt-drawing wheel 31 and the belt-feeding wheel 32 can slide along the translation rail 43 with the translation seat 44. The belt-drawing motor 45 and the belt-feeding motor 46 are installed on the translation seat 44. The belt-drawing motor 45 is connected to the belt-drawing wheel 31 in a transmission manner, and the belt-feeding motor 46 is connected to the belt-feeding wheel 32 in a transmission manner. Through the rotation of the belt-drawing motor 45 and the belt-feeding motor 46, the belt-drawing wheel 31 and the belt-feeding wheel 32 are driven to rotate respectively, so as to achieve the belt-drawing effect.

The avoidance motor 52 can drive the screw rod to rotate, and further drive the docking bin body 1 to slide along the avoidance slide rail 51 to achieve the above-mentioned avoidance effect.
