[0002] SMT (Surface Mount Technology) is a commonly used assembly technology and process in the current electronic equipment production industry.

[0003] In the patch process, material tape is needed. The material tape is set on a reel, and several reels are placed side by side on a base to form a clip. When the material tape on any reel is used up, the reel needs to be lifted by the corresponding lifting device, and then the reel is replaced. After the reel is replaced, it is put back into the clip.

[0057] 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.

[0058] After research, it was found that in the patch process, a material tape is needed. The material tape is set on a reel, and several reels are placed side by side on a base to form a clip. When the material tape on any reel is used up, the reel needs to be lifted by the corresponding lifting device, and then the reel is replaced. After the reel is replaced, it is put back into the clip.

[0059] However, in the process of using the lifting device to lift the reel for a long time, the contact part between the lifting device and the reel is prone to deformation under the action of long-term impact force, such as bending at a certain angle, and the bending direction cannot be controlled, causing the reel to tilt to a certain extent when the lifting device lifts the reel, and the tilting direction cannot be determined. However, when changing the reel, the reel needs to be kept upright. If the reel is tilted, the accuracy of reel changing will be affected.

[0060] Based on the above research, Figure 1 As shown, the embodiment of the present disclosure provides a SMT feeding clip device, including: a base 1 and a lifting mechanism 2, the base 1 is suitable for plugging a plurality of clip seats 10, and the lifting mechanism 2 is arranged on one side of the base 1, and is used to lift or lower the clip seat 10. A lifting fork block 3 is installed at the movable end of the lifting mechanism 2, and a lifting assembly 4 is rotatably arranged at the bottom of the lifting fork block 3, the lifting fork block 3 is suitable for forking the clip seat 10, and the lifting assembly 4 is suitable for lifting the clip seat 10 to keep it horizontal when the clip seat 10 is lifted to the maximum stroke, and when the lifting fork block 3 is put back into the clip seat 10, the lifting assembly 4 will push away other clip seats 10 on both sides of the clip seat 10 to prevent the clip seat 10 from colliding with the clip seats 10 on both sides thereof, causing damage.

[0061] Reference Figure 4In at least one embodiment, the lifting assembly 4 has a lifting plane 41 on the side facing the magazine seat 10, and a guiding arc surface 42 on the side away from the magazine seat 10. The lifting plane 41 is suitable for lifting the magazine seat 10 to keep it horizontal, and the guiding arc surface 42 is suitable for arranging the magazine seats 10 on both sides of the magazine seat 10 to achieve the above effect. Therefore, when any magazine seat 10 is changed, the lifting mechanism 2 drives the lifting fork block 3 to engage with the magazine seat 10, and pushes the magazine seat 10 to lift up until it reaches the maximum stroke. Then the lifting assembly 4 rotates until the lifting plane 41 abuts against the bottom of the magazine seat 10, and lifts the magazine seat 10 to keep it horizontal. At this time, the effect can be referred to Figure 5 After the clip seat 10 is changed, the lifting mechanism 2 drives the lifting fork block 3 to drive the clip seat 10 to descend, and the guiding arc surface 42 of the lifting assembly 4 separates the clip seats 10 on both sides of the clip seat 10 to prevent the clip seat 10 from colliding with the clip seats 10 on both sides and causing damage. The effect at this time can be referred to Figure 6 It is also worth mentioning that the lifting assembly 4 includes two support blocks 43 that are separately arranged, and the two support blocks 43 are arranged in a mirror image to lift the magazine seat 10. Specifically, the side of the support block 43 facing the magazine seat 10 is flat to form the above-mentioned lifting plane 41, and the side of the support block 43 away from the magazine seat 10 has a rounded corner to form the above-mentioned guiding arc surface 42. In addition, a separation spring 44 is arranged between the two support blocks 43 that are arranged in a mirror image, and the two ends of the separation spring 44 are respectively connected to the two support blocks 43, and the two support blocks 43 are elastically separated by the separation spring 44, so that a certain distance is formed between the two support blocks 43.

[0062] Reference Figure 3The bottom of the lifting fork block 3 is provided with a receiving groove 31, and the two support blocks 43 are retracted in the receiving groove 31. At this time, the separation spring 44 is compressed, and the two support blocks 43 are attached to each other. The top of the support block 43 also has a movable protrusion 45, and the thickness of the movable protrusion 45 is less than half the width of the receiving groove 31. The lifting assembly 4 includes a rotating shaft 46, which is respectively connected to the two movable protrusions 45. When the rotating shaft 46 rotates, it is suitable for driving the two movable protrusions 45 to rotate synchronously, that is, driving the two support blocks 43 to rotate synchronously around the rotating shaft 46. When the two support blocks 43 rotate out of the storage slot 31 until the lifting plane 41 abuts against the bottom of the magazine seat 10 and is horizontal, because the thickness of the two movable protrusions 45 is less than half the width of the storage slot 31, the two support blocks 43 can slide along the rotating shaft 46, that is, the side walls of the two support blocks 43 no longer abut against the inner wall of the storage slot 31, but the side walls of the two movable protrusions 45 can abut against the inner wall of the storage slot 31. Because of the setting of the above-mentioned separation spring 44, the two support blocks 43 are bounced away by the separation spring 44 until the side walls of the two movable protrusions 45 abut against the inner wall of the storage slot 31. In this state, in addition to maintaining parallelism, the two support blocks 43 are also separated by a certain distance, and the distance is slightly smaller than the distance between the two side discs of the magazine seat 10. That is to say, the lifting planes 41 on the two support blocks 43 respectively lift the two sides of the magazine seat 10 at this time, instead of lifting it to the material belt between the two side discs of the magazine seat 10, ensuring the stability of the reel. In order to drive the rotation shaft 46 to rotate, an electric actuator is installed on one side of the lifting fork block 3, and the electric actuator is connected to the rotation shaft 46 in a transmission manner. As an option, the electric actuator is a driving motor. When the lifting mechanism 2 drives the lifting fork block 3 to engage with the magazine seat 10 and push the magazine seat 10 to lift until it reaches the maximum stroke, the driving motor is started to drive the rotation shaft 46 to rotate to achieve the lifting effect of the above-mentioned support block 43. In addition, when the lifting fork block 3 needs to be put back into the magazine seat 10, the driving motor drives the rotation shaft 46 to rotate in the opposite direction to drive the support block 43 to rotate around the rotation shaft 46 toward the storage groove 31. At this time, the guide arc surface 42 will not only push away the magazine seats 10 on both sides of the lifted magazine seat 10 to prevent collision, but also make the support block 43 be stored in the storage groove 31 again along the guide arc surface 42 after the guide arc surface 42 contacts the storage groove 31, and restore the initial state.

[0063] Reference Figure 2In order to achieve the effect of the lifting mechanism 2 driving the lifting fork block 3 to rise or fall, in at least one embodiment, the lifting mechanism 2 includes a vertical pillar 21, and a lifting rail 22 is provided on one side of the vertical pillar 21. The lifting assembly 4 includes a lifting bracket 47, and the lifting bracket 47 is slidably arranged on the lifting rail 22, which is suitable for sliding up and down along the lifting rail 22. A lifting motor 23 is also installed on the vertical pillar 21, and the lifting bracket 47 is transmission-connected to the lifting motor 23, and the lifting motor 23 is suitable for driving the lifting bracket 47 to slide up and down along the lifting rail 22. Optionally, a screw rod is installed at the movable end of the lifting motor 23, and the lifting bracket 47 is threadedly connected to the screw rod. The lifting motor 23 can drive the screw rod to rotate, and further drive the lifting bracket 47 to slide up and down along the lifting rail 22 to achieve the above effect.

[0064] Reference Figure 2 , in order to achieve the effect that the base 1 slides horizontally to adjust the position of the base 1, the lifting fork block 3 lifts the clip seat 10 at different positions on the base 1. In at least one embodiment, the SMT feeding clip device also includes an adjusting slide rail 5, and the base 1 is slidably arranged on the adjusting slide rail 5, which is suitable for sliding along the adjusting slide rail 5. An adjusting motor 51 is installed at one end of the adjusting slide rail 5, and the adjusting motor 51 is transmission-connected with the base 1, which is suitable for driving the base 1 to slide along the adjusting slide rail 5. Optionally, a screw rod is installed at the movable end of the adjusting motor 51, and the base 1 is threadedly connected with the screw rod. The adjusting motor 51 can drive the screw rod to rotate, and further drive the base 1 to slide along the adjusting slide rail 5. When the lifting fork block 3 is put back into the clip seat 10, the adjusting motor 51 drives the base 1 to slide along the adjusting slide rail 5, and the clip seat 10 facing the lifting fork block 3 is replaced with other clip seats 10 in the SMT feeding clip device to continuously feed materials.

[0065] It is also worth mentioning that a plurality of slots 12 are provided on the base 1 , and the slots 12 are suitable for inserting the magazine holders 10 , so that a plurality of magazine holders 10 can be neatly arranged on the base 1 .

In at least one embodiment, a clamping block 11 is further provided on the base 1, and the lifting fork block 3 can be inserted into the clamping block 11 and clamped with the clamping block 11, so that when the lifting fork block 3 is lifted, the lifting fork block 3 is lifted up by the clamping block 11.

[0067] On the other hand, the magazine seat 10 is internally mirrored with two sets of pillars to position reels of two different specifications.

[0068] In addition, at least one embodiment further provides a feeding method for a clip device, and the feeding method is performed using the SMT feeding clip device described above, and the feeding method includes: when any clip seat 10 is changed, the lifting mechanism 2 drives the lifting fork block 3 to engage with the clip seat 10, and pushes the clip seat 10 to lift until it reaches the maximum stroke, then the lifting assembly 4 rotates until the lifting plane 41 abuts against the bottom of the clip seat 10, and lifts the clip seat 10 to keep it horizontal, then after the clip seat 10 is changed, the lifting mechanism 2 drives the lifting fork block 3 to drive the clip seat 10 to descend, and the guide arc surface 42 of the lifting assembly 4 separates the clip seats 10 on both sides of the clip seat 10.
