Description

Technical Field

[0001] The present invention belongs to the technical field of SMT tape, and particularly relates to a feeding device for a multi-position double-bin type SMT tape reel. Background Art

[0002] SMT is the abbreviation of Surface Mounted Technology, which is the most popular technology and process in the electronic assembly industry.

[0003] Currently, during the feeding process of the tape reel on the SMT tape splicing machine, generally multiple side-by-side positions are adopted, and each position is successively transferred and aligned with the feeding station. Moreover, each time a tape reel is completed, it needs to be shifted once for alignment. Therefore, there are the following technical defects:

[0004] 1) The layout of each position not only needs to be completely separated, but also there should be no interference between them. Therefore, the number of positions arranged in the formed space is small, and at the same time, due to space limitations, the frequency of replenishing the positions is relatively high, that is, the continuity of automatic feeding is poor, which further affects the feeding efficiency;

[0005] 2) After each tape reel is completed, it is necessary to perform displacement and transfer. Once there is an alignment deviation, it will cause the SMT tape to be distorted, resulting in a relatively high probability of tape jamming or blockage, and unable to meet the feeding requirements;

[0006] 3) There is no connection between each position and they are completely independent. Therefore, it occupies a large space and cannot meet the side-by-side feeding of the SMT tape of a compact SMT tape splicing machine. Summary of the Invention

[0007] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an improved feeding device for a multi-position double-bin type SMT tape reel.

[0008] To achieve the above purpose, the technical solution adopted by the present invention is:

[0009] A feeding device for a multi-level dual-bin type SMT tape reel, which includes a base, a plurality of tape rails arranged side by side on the base, and bins slidably installed on each tape rail. The tape rails extend along the width direction of the base. Each bin includes a bin seat slidable on the tape rail, an upper bin body and a lower bin body provided on opposite sides of the bin seat. The upper bin body is rotatably mounted on the bin seat around a pivot extending along the length direction of the base, and an arc-shaped material guiding portion extending forward and upward is formed at the bottom of the upper bin body. The lower bin body is located below the rear side of the upper bin body. The SMT tape reel is freely unwound and placed in the upper bin body and the lower bin body. When every two adjacent bins are aligned side by side, the upper and lower bin bodies are misaligned and complementary in the front-rear and up-down directions. At least two SMT tape reels that can be selected for alignment can be provided at the same feeding position. Moreover, the SMT tape unwound from one lower bin body can form feeding by adhering to the floating or constant arc-shaped material guiding portion of the upper bin body of another bin. At the same time, when each bin moves along the tape rail, the lower SMT tape reel can lift the upper bin body on the moving path to rotate upward around the pivot to form an avoidance, and the upper bin body gradually resets around the pivot after losing the top contact.

[0010] Preferably, in the projection of each bin in the extending direction of the pivot, the horizontal distance between the centers of the two SMT tape reels is less than the vertical distance between the centers of the two SMT tape reels. Based on the layout of the distances, the alignment layout of the two SMT tape reels in a space as small as possible is further realized. The advantages of this are as follows: 1. It can meet the feeding of multiple trays at the same position; 2. It can further reduce the volume of each bin itself, and the space utilization rate is also greatly improved.

[0011] In some specific embodiments, the horizontal distance between the centers of the two SMT tape reels is at least half of the vertical distance between the centers of the two SMT tape reels. In this way, the preparation layout of multiple SMT tape reels can be carried out in a limited space to meet the needs of automatic feeding of SMT tapes.

[0012] According to a specific implementation and preferred aspect of the present invention, when every two adjacent bins are aligned side by side, the bottoms and tops of the two SMT tape reels for making up the position overlap partially in the projection along the tape rail direction. On the premise of meeting the feeding of multiple trays, the overlapping can save space at least in the height direction to optimize the entire bin structure.

[0013] In some specific embodiments, the height of the overlapping part is 1 / 4 to 1 / 3 of the radius of the SMT tape reel. Generally, the height of the overlapping part is 1 / 4 of the radius of the SMT tape reel. Under this parameter limitation, the cooperation of the unwinding of the two SMT tape reels can be better realized, so that the arc-shaped material guiding portion of the upper bin body can assist the unwinding of the SMT tape reel in the corresponding lower bin body under the best tension.

[0014] According to another specific implementation and preferred aspect of the present invention, an arc-shaped mounting surface is formed at the top of the bin base, and the upper bin body is rotatably mounted on the arc-shaped mounting surface through a pivot. The bottom plate of the upper bin body is an arc concentric with the center of the SMT tape reel to be mounted, and the upper bin body is erected on the arc-shaped mounting surface from a part of the side of the arc-shaped bottom plate; the lower bin body is fixed at the lower part of the bin base and is located on the opposite side of the side where the upper bin body is located. Based on the layout of the arc-shaped mounting surface, the flip mounting of the upper bin body is realized, and at the same time, based on the relative layout of the lower bin body, the feeding requirements of multiple bins for alignment are met.

[0015] Preferably, an insertion module is formed on one side of the bottom of each upper bin body, and an insertion slot is provided on the arc-shaped mounting surface of each bin base. Among them, the insertion module is synchronously disengaged from or inserted into the insertion slot as the upper bin body flips, and the upper bin body is supported on the bin base based on the cooperation of the insertion module and the insertion slot. The insertion module and the insertion slot are in a limiting and guiding cooperation (note that the cooperation here is not a tenon and mortise groove cooperation method), so that the upper bin body will not cause lateral movement when flipping, and the probability of accidental rubbing between adjacent two bins is eliminated.

[0016] According to another specific implementation and preferred aspect of the present invention, an extension edge extending outward from the side plate of the bin body is formed at the front end of the upper bin body, and an arc-shaped material guiding part with an open lower part is formed between the two extension edges and the arc-shaped bottom plate. Based on the occlusion formed by the extension part, the mutual interference between the hoppers during feeding is avoided; at the same time, according to the change of the instantaneous tension, the arc-shaped material guiding part forms a floating match as the upper bin body flips, so as to meet various requirements of SMT tape feeding.

[0017] In some specific embodiments, the extension length of the extension edge gradually increases from bottom to top along the extension direction of the arc-shaped bottom plate. Because, as the tape moves upward and forward and gradually moves away from the SMT tape reel, if the extension length does not change, the interference rate of adjacent hopper feeding caused by large-scale bin offset will increase significantly.

[0018] In addition, in the projection of each bin in the extension direction of the pivot, the pivot is located within the area formed by the vertical center lines of the two SMT tape reels, and the pivot is also located within the area formed by the horizontal center lines of the two SMT tape reels. Based on the position limitation of the pivot, it is more beneficial to the layout of the two SMT tape reels being relatively close to each other, thereby optimizing the size of each bin.

[0019] At the same time, in the projection of each bin in the extension direction of the pivot, the front part of the upper bin body is exposed outside the front side of the bin base. The main technical purpose of such a setting is that the SMT tape unwound from the lower bin body can fit the arc-shaped material guiding part at the front end of the upper bin body under different tensions, so as to avoid the feeding interference of the SMT tape caused by the bin base.

[0020] Due to the application of the above technical solutions, the present invention has the following advantages compared with the prior art:

[0021] During the feeding of the tape reels on the existing SMT tape feeding machine, the layout of each tape position not only needs to be completely separated, but also there should be no interference between them. Therefore, the number of tape positions arranged in the formed space is small. At the same time, due to space limitations, the frequency of replenishing the tape positions is relatively high, that is, the continuity of automatic feeding is poor, which in turn affects the efficiency. In addition, after each tape reel is completed, displacement transfer needs to be carried out. Once there is a misalignment, it will cause the SMT tape to be distorted, resulting in a relatively high probability of tape jamming or blockage, and unable to meet the feeding requirements. Moreover, there is no any connection between each tape position and they are completely independent. Therefore, it occupies a large space and cannot meet the side-by-side feeding of SMT tapes for compact SMT tape feeding machines and other deficiencies. However, the present invention cleverly solves various existing deficiencies through the overall design of the feeding device for the multi-position dual-bin type SMT tape reel. After adopting the feeding device for the multi-position dual-bin type SMT tape reel, based on multiple bins arranged side by side and aligned, due to the front-back and up-down misalignment of the upper bin body and the lower bin body in alignment, that is, in this alignment, two SMT tape reels can feed synchronously or successively. At the same time, during feeding, based on the floating or constant tension formed by the upper bin body, it assists the SMT tape reel in the lower bin body to unwind and feed. Therefore, on the one hand, based on the complementary and misaligned upper and lower bin bodies, the present invention not only meets the feeding of two SMT tape reels at the same position, but also the upper bin body can form the tension assistance for the unwinding of the lower SMT tape reel (whether it is floating or constant tension), avoiding the feeding interference between multiple stations. At the same time, it can meet the side-by-side layout of multiple SMT tape reels with complementary interference in a limited space, improving the continuity of automatic feeding. On the other hand, based on the movement avoidance formed by the flipping of each upper bin body, multiple tape positions are coordinated. It not only shortens the vertical distance between the two SMT tape reels placed in each bin to optimize the structure of the bin, but also facilitates the shifting of each bin for replenishing the SMT tape reel.

[0040] As Figures 1 to 9 shown, the feeding device of the multi-level double-bin type SMT tape reel in this embodiment includes a base 1, a plurality of tape rails 2 arranged side by side on the base 1, and bins 3 slidably installed on each tape rail 2, wherein the tape rails 2 extend along the width direction of the base.

[0041] Each bin 3 includes a bin base 30 that slides on the material rail 2, an upper bin body 31 and a lower bin body 32 provided on opposite sides of the bin base 30. The upper bin body 31 is rotatably mounted on the bin base 30 around a pivot axis s extending in the length direction of the base 1, and an arc-shaped material guiding portion 31a extending forward and upward is formed at the bottom of the upper bin body 31; the lower bin body 32 is located below the rear side of the upper bin body 31, and the lower bin body 32 is fixed to the lower part of the bin base 30 and on the opposite side of the side where the upper bin body 31 is located. The upper bin body 31 is a separate semi-circular bin body structure, and the lower bin body 32 forms a semi-circular bin body structure based on the bin base 30. The SMT tape reels J can be freely unwound and placed in the upper bin body 31 and the lower bin body 32.

[0042] In some specific embodiments, an arc-shaped mounting surface 300 is formed at the top of the bin base 30, and the upper bin body 31 is rotatably mounted on the arc-shaped mounting surface 300 through the pivot axis s. The bottom plate of the upper bin body 31 is arc-shaped and concentric with the center of the SMT tape reel to be mounted, and the upper bin body 31 is mounted on the arc-shaped mounting surface 300 from a part of the side of the arc-shaped bottom plate. Based on the layout of the arc-shaped mounting surface, the flip mounting of the upper bin body can be realized, and at the same time, based on the relative layout of the lower bin body, the need for alignment and feeding of multiple bins can be met.

[0043] An insertion module 31b is formed on one side of the bottom of each upper bin body 31, and an insertion slot c is provided on the arc-shaped mounting surface 300 of each bin base 30. The insertion module 31b is synchronously disengaged from or inserted into the insertion slot c as the upper bin body 31 flips, and the upper bin body 31 is supported on the bin base 30 based on the cooperation between the insertion module 31b and the insertion slot c. The insertion module and the insertion slot are in a limiting and guiding cooperation (note that the cooperation here is not a tenon and mortise slot cooperation method), so that the upper bin body will not cause lateral movement when flipping, and the probability of accidental rubbing between adjacent two bins is eliminated. An extension edge extending outward from the bin body side plate is formed at the front end of the upper bin body 31, and an arc-shaped material guiding portion 31b with an open bottom is formed between the two extension edges and the arc-shaped bottom plate. Based on the occlusion formed by the extension part, the mutual interference between the hoppers during feeding is avoided. The extension length of the extension edge gradually increases from bottom to top along the extension direction of the arc-shaped bottom plate. Because, as the tape moves upward and forward and gradually moves away from the SMT tape reel, if the extension length does not change, the interference rate of feeding between adjacent hoppers caused by large bin offsets will be greatly increased.

[0044] In some specific embodiments, in the projection of each magazine 3 in the pivot extension direction, the horizontal distance between the centers of two SMT tape reels J is less than the vertical distance between the centers of the two SMT tape reels J. Based on this distance layout, the alignment layout of the two SMT tape reels is further realized in a space as small as possible. The advantages of this are as follows: 1. It can meet the feeding of multiple trays at the same position; 2. It further reduces the volume of each magazine itself, and the space utilization rate is also greatly improved. In this example, the horizontal distance between the centers of the two SMT tape reels is at least half of the vertical distance between the centers of the two SMT tape reels. At the same time, in the projection of each magazine 3 in the pivot s direction, the pivot s is located within the area formed by the vertical centerlines of the two SMT tape reels J, and the pivot s is also located within the area formed by the horizontal centerlines of the two SMT tape reels J. Based on the position limitation of the pivot, it is more conducive to the layout where the two SMT tape reels are relatively close to each other, thereby optimizing the size of each magazine. In addition, in the projection of each magazine 3 in the pivot extension direction, the front part of the upper magazine body 31 is exposed outside the front side of the magazine base. The main technical purpose of this setting is that the SMT tape unrolled from the lower magazine body 32 can fit the arc-shaped guiding part at the front end of the upper magazine body 31 under different tensions, so as to avoid the feeding interference of the SMT tape caused by the magazine base.

[0045] In this example, the above-mentioned magazines 3 are aligned side by side relative to each other. When every two adjacent magazines 3 are aligned side by side, the upper magazine body 31 and the lower magazine body 32 are misaligned and complementary in the front-back and up-down directions (the upper magazine body 31 and the lower magazine body 32 of the two magazines 3 are misaligned and complementary so that the upper magazine body 31 of one magazine 3 and the lower magazine body 32 of another magazine 3 are aligned in the front-back direction and complementary in the up-down direction). At least two SMT tape reels (the aligned upper magazine body 31 and lower magazine body 32) that can be selected for alignment can be provided at the same loading position. And the SMT tape unrolled from one lower magazine body 32 can form feeding by fitting the floating or constant arc-shaped guiding part 31a of the upper magazine body 31 of another magazine 3. At the same time, when each magazine 3 moves along the material track, the lower SMT tape reel J can lift the upper magazine body 31 on the moving path to rotate upward around the pivot s to form an avoidance, and the upper magazine body 31 gradually resets around the pivot s after losing the top contact.

[0046] In some specific embodiments, the aligned upper warehouse body 31 and the lower warehouse body 32 can be fed successively or simultaneously at the same position. In order to assist the feeding of the lower warehouse body 32, in general, the upper warehouse body 31 is positioned and mounted on the arc-shaped mounting surface 300, and the insertion module 31b is in a state of being inserted in the insertion slot c. The SMT tape unrolled from the aligned lower warehouse body 32 enters the arc-shaped guide portion 31a along the bottom of the upper warehouse body 31 for guidance under constant tension; once the SMT tape is subjected to an instantaneous change in tension during the feeding process, the aligned upper warehouse body 31 rotates around the pivot s and lifts upward, and as the force changes, the upper warehouse body 31 can be in a floating state of flipping up and down, thereby optimally assisting the feeding of the SMT tape. Note: at this time, the insertion module 31b generally remains in the insertion slot c and moves with it, and will only detach from the insertion slot c when the tension is too large.

[0047] In addition, when every two adjacent silos 3 are aligned side by side, the two SMT tape rolls J that fill in the gaps partially overlap at the bottom and top in the projection along the material track direction. Under the premise of satisfying the multi-reel tape feeding, the overlap can save space at least in the height direction to optimize the entire silo structure. The height of the overlapping part is 1 / 4 to 1 / 3 of the radius of the SMT tape roll. Generally, the height of the overlapping part is 1 / 4 of the radius of the SMT tape roll. Under this parameter restriction, the cooperation of the unwinding of the two SMT tape rolls can be better achieved so that the arc-shaped material guide part of the upper silo body assists the unwinding of the SMT tape roll in the corresponding lower silo body under the optimal tension.

[0048] Finally, the bin seat 30 slides on the material rail 2 through the sliding module 301 at the bottom, and in order to further avoid movement interference between each adjacent group of bins 3 and eliminate the displacement of adjacent bins 3 when a single bin 3 moves relative to the material rail 2, magnetic adsorption can be used to assist. In this way, as long as the force provided by the magnetic adsorption is greater than the thrust generated when avoiding movement during displacement, the displacement of a single bin 3 relative to the material rail 2 for replenishing materials can be implemented.

[0049] In summary, after adopting the feeding device of the multi-level double-bin type SMT tape reel, based on multiple bins arranged side by side and aligned, due to the front-back and up-down misalignment of the upper bin body and the lower bin body in alignment, that is, in this alignment, two SMT tape reels can feed synchronously or successively. At the same time, during feeding, based on the floating or constant tension formed by the upper bin body, it assists the SMT tape reel in the lower bin body to unwind and feed. Therefore, on the one hand, based on the complementary and misaligned layout of the upper and lower bin bodies, the present invention not only satisfies the feeding of two SMT tape reels at the same position, but also the upper bin body can form a tension assist for the unwinding of the lower SMT tape reel (whether it is floating or constant tension), avoiding the feeding interference between multiple workstations. At the same time, it can meet the complementary interference side-by-side layout of multiple SMT tape reels within a limited space, improving the continuity of automatic feeding; on the other hand, based on the movement avoidance formed by the flipping of each upper bin body, it not only shortens the vertical distance between the two SMT tape reels placed in each bin to optimize the structure of the bin, but also facilitates the shifting of each bin for replenishing the SMT tape reel; on the third hand, based on the layout of the horizontal distance and the vertical distance, it further realizes the alignment layout of two SMT tape reels in the smallest possible space, not only satisfying the feeding of multiple trays at the same position, but also further reducing the volume of each bin itself, and greatly improving the space utilization rate. At the same time, the horizontal distance between the centers of the two SMT tape reels is at least half of the vertical distance between the centers of the two SMT tape reels, so that the layout of multiple SMT tape reels can be prepared within a limited space to meet the needs of SMT tape automatic feeding; on the fourth hand, on the premise of satisfying the feeding of multiple trays, the overlap can save space at least in the height direction to optimize the entire bin structure. Generally, the height of the overlapping part is 1 / 4 of the radius of the SMT tape reel. Under this parameter limitation, it can better realize the cooperation of the unwinding of the two SMT tape reels so that the arc-shaped guiding part of the upper bin body assists the unwinding of the SMT tape reel in the corresponding lower bin body under the best tension; on the fifth hand, based on the layout of the arc-shaped mounting surface, it realizes the flipping installation of the upper bin body. At the same time, based on the relative layout of the lower bin body, it meets the feeding needs of multiple bins. In addition, with the limiting and guiding cooperation of the insertion module and the insertion slot (note that the cooperation here is not the tenon and mortise cooperation method), it ensures that the upper bin body will not cause lateral movement when flipping, eliminating the probability of accidental rubbing between adjacent two bins; on the sixth hand, based on the occlusion formed by the extension part, it avoids the mutual interference between the hoppers during feeding; at the same time, according to the change of the instantaneous tension, based on the floating matching formed by the arc-shaped guiding part following the flipping of the upper bin body, it meets various needs of SMT tape feeding; on the seventh hand, the length of the multi-extension of the extension edge gradually increases from bottom to top along the extension direction of the arc-shaped bottom plate. Because, as the tape moves upward and forward and gradually moves away from the SMT tape reel, if the extension length does not change, it will greatly increase the interference rate of the feeding of adjacent hoppers caused by the offset of the bin;The eighth aspect is based on the position definition of the pivot, which is more conducive to the layout of two SMT tape reels being relatively close to each other, thereby optimizing the size of each bin. At the same time, in the projection of each bin in the extension direction of the pivot, the front part of the upper bin body is exposed on the front side of the bin seat. The main technical purpose of such a setting is that the SMT tape unrolled from the lower bin body can fit the arc-shaped guiding part at the front end of the upper bin body under different tensions, so as to avoid the feeding interference of the SMT tape caused by the bin seat.;

[0050] The above embodiments are only for illustrating the technical concept and characteristics of the present invention, and their purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and should not be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
