[0037] Usually, the label is attached to a strip-shaped base tape to form a label tape with labels, and then wound into a roll for storage and subsequent use. Figure 1 Schematic structural diagram of an embodiment of the label conveying device 210, Figure 2 is Figure 1 side view of. The label conveying device 210 in this embodiment is used to convey the label tape, including a conveying device 210 and a label pressing device. The conveying device 210 is used to convey the label tape along a set path. The label pressing device is arranged on the conveying path and is used to press the label on the label tape from the back of the label tape so that the corresponding label can be obtained by the picking device for labeling in subsequent processes.

[0038] The conveying device 210 includes a driving roller and a plurality of conveying rollers. The driving roller is used to drive the label tape to move, and the conveying rollers are used to convey and guide the label tape so that the label tape is conveyed along a set path. In this embodiment, the conveying device 210 includes a first driving roller 211 and a second driving roller 212. The first driving roller 211 is used to pull the label tape out of the label roll, and the second driving roller 212 is used to wind up the label tape at the rear end of the conveying path. After the label tape is led out from the unwinding reel 213, it reaches the first conveying roller 214, and then is driven by the first driving roller 211 so as to apply a force to the label tape, so that the label tape can be unwound smoothly. A first pressing roller 215 is arranged on one side of the first driving roller 211. The first pressing roller 215 abuts against one side of the first driving roller 211, and the label tape is squeezed between the two. Thus, when the first driving roller 211 rotates, the label tape can be conveyed backward through friction. The first pressing roller 215 plays a role in pressing the label tape to ensure the stable conveyance of the label tape.

[0039] It further includes a second conveying roller 216, a third conveying roller 217, a fourth conveying roller 218 and a fifth conveying roller 219. The second conveying roller 216 and the third conveying roller 217 are respectively arranged on both sides of the top-label device and are used to guide the label tape to pass through the top-label device. The fourth conveying roller 218 and the fifth conveying roller 219 are used to guide the label tape sent out from the top-label device to the second driving roller 212 for winding up.

[0040] In other embodiments, after the label tape passes through the fifth conveying roller 219, it first bypasses the first driving roller 211 and then is sent to the second driving roller 212 for winding up. A second pressing roller 2110 is also arranged beside the first driving roller 211 and is used to press the label tape sent from the fifth conveying roller 219 to the first driving roller 211, which helps the smooth conveyance of the label tape and ensures that the speed of the label tape sent out from the unwinding place is the same as the speed of the label tape sent into the winding-up place, thus ensuring the smoothness of the conveyance. Therefore, the rotation speed of the second driving roller 212 for winding up can be the same as that of the first driving roller 211, or can be reasonably adjusted according to specific needs, as long as the rotation speed of the second driving roller 212 satisfies that the label tape will not be pulled between the first driving roller 211 and the second pressing roller 2110 during the winding-up process.

[0041] Figure 3 It is a schematic structural diagram of an embodiment of the top-label device, Figure 4 For Figure 3 the top view, Figure 5 For Figure 4 the sectional view taken along line A-A in Figure 6 It is a schematic structural diagram of an embodiment of the carrying platform 220. At the same time, refer to Figure 1 and Figures 3 to 6, the top - marking device includes a bearing platform 220, a material - pressing mechanism 230 and a top - marking mechanism 240. The conveying device 210 spreads the label tape on the bearing platform 220. The material - pressing mechanism 230 includes a material - pressing head 231 and a material - pressing head lifting mechanism 232. The material - pressing head lifting mechanism 232 can move the material - pressing head 231 closer to or farther from the bearing platform 220, and is used to press the label tape on the bearing platform 220, which can be realized by a cylinder specifically. The top - marking mechanism 240 includes a top - marking head 241 and a top - marking head adjusting mechanism 242 for driving the movement of the top - marking head 241. A through - hole 221 for the top - marking head 241 to pass through is provided on the bearing platform 220. The top - marking head 241 is arranged such that the top - marking head 241 can pass through the through - hole 221 and abut against the label corresponding to the through - hole 221 from the back of the label tape. Since conveying rollers are respectively arranged on the front and rear sides of the bearing platform 220 in the label - tape conveying direction, the label tape can pass between the material - pressing head 231 and the bearing platform 220 by bypassing the surfaces of the two conveying rollers, and the label tape is parallel to the upper surface of the bearing platform 220. Therefore, when the material - taking head in the subsequent process takes the label on the label tape, the top - marking device can jack up the corresponding label from the back of the label tape, which is convenient for material taking.

[0042] A window 2311 is provided on the material - pressing head 231. The position of the window 2311 corresponds to the position of the through - hole 221 on the bearing platform 220, and the edge of the window 2311 can surround the through - hole 221 inside. Therefore, the material - pressing head 231 can press the label tape around the position corresponding to the through - hole 221 around the window 2311, so that the label tape corresponding to the through - hole 221 and the label on it can be smoothly flattened, which is convenient for material taking.

[0043] A number of through holes 221 are provided on the carrying platform 220. The through holes 221 are arranged in a direction perpendicular to the conveying direction of the label tape. Therefore, within the range of the window 2311 of the pressing head 231, the peripheries of multiple labels can be pressed tightly at one time. Pressing the labels at one time facilitates picking and pasting multiple times, improving efficiency. The number of the top label heads 241 can be equal to that of the through holes 221, or less than the number of the through holes 221. If the number of the top label heads 241 is set to be less than the number of the through holes 221, a top label head adjusting device can be used to adjust the position of the top label head 241 so that the top label head 241 can reach the positions of all the through holes 221 for top labeling. The top labeling mechanism 240 is respectively provided with a top label head 241 corresponding to the position of each through hole 221, or a top label head 241 that can move along the arrangement direction of the through holes 221 can also be provided to perform top labeling corresponding to the required through holes 221 as needed. In the illustrated embodiment, a pair of top label heads 241 are provided in the top labeling device, and four through holes 221 are provided on the carrying platform 220. This pair of top label heads 241 are installed on the top label head adjusting mechanism 242. The top label head adjusting mechanism 242 includes a first top label head adjusting mechanism 2421 and a second top label head adjusting mechanism 2422. The first top label head adjusting mechanism 2421 can perform lifting adjustment on the top label head 241, and the second top label head adjusting mechanism 2422 can move the first top label head adjusting mechanism 2421 along the arrangement direction of the through holes 221, so that the top label head 241 can be correspondingly moved to correspond to each through hole 221, so as to lift the label at the corresponding position. Both the first top label head adjusting mechanism 2421 and the second top label head adjusting mechanism 2422 can be implemented by air cylinders.

[0044] Generally speaking, edge holes will be provided at the edges of the label tape carrying labels for positioning operations during use. In this embodiment, positioning pins 2312 can be provided on the side of the pressing head 231 facing the carrying platform 220. When the pressing head 231 moves towards the carrying platform 220, the positioning pins 2312 can be inserted into the edge holes, thereby realizing the positioning of the label tape, which helps to accurately perform top labeling and picking. Correspondingly, avoidance holes 222 can be provided on the carrying platform 220 at the positions corresponding to the positioning pins 2312 to prevent interference between the movement of the positioning pins 2312 and the carrying platform 220.

[0045] In some embodiments, the pressing head 231 extends in a direction perpendicular to the conveying direction of the label tape, and the extension length can cover the width of the label tape, thereby forming a pressing head 231 structure spanning above the label tape. Positioning pins 2312 are provided on both sides of the pressing head 231 corresponding to the edges of the label tape, so that positioning can be performed respectively from both sides of the label tape, ensuring that the label tape is in the correct position, and avoiding the situation that the label tape is offset, resulting in the position of the label not corresponding to the through hole 221, which makes it impossible to smoothly perform top labeling and picking and affects the smooth progress of the labeling work.

[0046] To further ensure the position of the label tape during the conveying process and prevent the label tape from shifting, a limiting block 223 can be provided in the area of the bearing platform 220 corresponding to the through hole 221. The label tape passes between the limiting blocks 223. Therefore, the limiting block 223 can be used to limit the two side edges of the label tape to prevent the label tape from shifting when passing through the area of the bearing platform 220 where the through hole 221 is provided. Correspondingly, an avoidance position 2313 for avoiding the limiting block 223 is provided on the side of the pressing head 231 facing the bearing platform 220. Further, in other parts of the bearing platform 220, limiting members 224 for limiting the two side edges of the label tape can also be provided, and these limiting members 224 are in corresponding positions in the label tape conveying direction with the above-mentioned limiting block 223.

[0047] Figure 6 Fig. shows a specific embodiment of the bearing platform 220. The figure shows a partial structure on the back of the bearing platform 220 of this embodiment. Corresponding to the position where the through hole 221 is provided, a groove 225 is provided on the back of the bearing platform 220. The groove 225 communicates with the through hole 221. The function of the groove 225 is to reduce the depth of the through hole 221, which helps to reduce the processing difficulty. And the groove 225 can provide a moving space for the top label head 241, which helps to reduce the distance setting between the top label head 241 and the bearing platform 220, making the structure compact. Guide surfaces 226 are also provided on both sides of each through hole 221 in the groove 225. The two guide surfaces 226 are inclined in the direction of increasing distance from the side wall of the through hole 221, forming an inclined surface extending from a position away from the through hole 221 to the position of the through hole 221, which can guide the top label head 241 and help the top label head 241 to smoothly pass into the through hole 221.

[0048] In some embodiments, the label conveying mechanism may further include a detection mechanism 250. The detection mechanism 250 is provided in front of the top label device and is used to detect the presence or absence of labels on the label tape before the top label device removes the labels. The detection mechanism 250 can adopt a transparent sensor. For example, if a certain place on the label tape appears transparent, it can be recognized by the detection mechanism 250 that there is no label at that place.

[0049] Through the label conveying device 210 of the above embodiment, the labels on the label tape can be conveyed to the set position (the position of the through hole 221), which is convenient for subsequent processes to pick up and label at this position, helps to improve the labeling accuracy, and thus meets the labeling requirements of some products with high label position accuracy. And for micro-miniature labels, picking up the labels at the set position and then moving the labels to the position of the product for labeling can ensure the accuracy of the label position. Therefore, the present invention can be applied to the removal and labeling of micro-miniature labels.

[0050] Figure 7 Schematic diagram of the structure of an embodiment of the labeling deviceFigure 8 The structural schematic diagram of an embodiment of the pick-up head driving mechanism is shown. Meanwhile, referring to Figure 7 and 8 , the labeling device provided in this embodiment includes a labeling mechanism 260 and the label conveying device 210 of any previous embodiment. The label conveying device 210 is used to convey the label to a set position and perform label topping at this position through the top label head 241. The labeling mechanism 260 includes a pick-up head 261 and a pick-up head driving mechanism. The pick-up head driving mechanism is arranged to drive the pick-up head 261 to move to the corresponding top label head 241 to pick up the label and move to the product to be labeled to perform labeling, realizing the conveying, positioning, topping, picking up, and labeling of the label, which helps to improve the labeling accuracy. The pick-up head 261 can adopt a suction nozzle structure and pick up the label through the action of vacuum adsorption, so as to remove the label from the label tape.

[0051] Specifically, the pick-up head driving mechanism includes a first moving mechanism 262, a second moving mechanism 263, a third moving mechanism 264, and a rotating mechanism 265. The specific directions are referenced by the coordinate axes in the figure, where:

[0052] The pick-up head 261 is connected to the third moving mechanism 264;

[0053] The first moving mechanism 262 is used to drive the second moving mechanism 263 to reciprocate along the Y-axis;

[0054] The second moving mechanism 263 is used to drive the rotating mechanism 265 to reciprocate along the X-axis;

[0055] The rotating mechanism 265 is used to drive the third moving mechanism 264 to rotate around the Y-axis;

[0056] The third moving mechanism 264 is used to drive the pick-up head 261 to move telescopically.

[0057] The first moving mechanism 262, the second moving mechanism 263, and the third moving mechanism 264 can select corresponding specifications of cylinders or electric slide tables as required. The rotating mechanism 265 can select a corresponding specification of a rotary cylinder as required. The starting and ending positions of each moving mechanism can be determined during pre-adjustment, and conventional position sensors such as photoelectric switches are used for position identification. Thus, the pick-up head 261 can move along the X and Y axes through the pick-up head driving mechanism for movement between the label conveying device 210 and the product to be labeled. And it can rotate around the Y-axis direction to achieve labeling at multiple positions, such as the top surface, side surface, or inclined surface, etc. The third moving mechanism 264 realizes the telescopic movement of the pick-up head 261. Thus, after the pick-up head 261 is adjusted to the required angle through the rotating mechanism 265, the telescopic movement of the pick-up head 261 is realized through the third moving mechanism 264 to perform labeling in this direction.

[0058] Figure 9It is a schematic structural diagram of an embodiment of the first moving mechanism 262 in the material taking head driving mechanism. Refer to Figure 9 , the first moving mechanism 262 includes a first slide rail 2621 extending along the Y-axis, a first slider 2622 slidably arranged on the first slide rail 2621, an inclined slide rail extending in an inclined direction from back to front, a second slider 2624 slidably arranged on the inclined slide rail, and a power element 2625 for driving the second slider 2624 to move in the X-axis direction. The second moving mechanism 263 is fixedly connected to the first slider 2622 and the second slider 2624. Therefore, by driving the second slider 2624 to move in the X-axis direction by the power element 2625, the second moving mechanism 263 can be made to move along the extending direction of the first slide rail 2621 (i.e., the Y-axis direction). The power element 2625 can adopt a mechanism of driving a lead screw to rotate by a motor. The second slider 2624 is connected to the lead screw, so that the second slider 2624 can be driven to slide along the second slide rail 2623 by driving the lead screw to rotate by the motor. This mechanism can arrange the power element 2625 in the X direction and convert the movement output by the power element 2625 in the X-axis direction into the movement of the second moving mechanism 263 in the Y-axis direction, saving space in the Y-axis direction, being beneficial to optimizing the layout, shortening the stroke of the material taking head 261 moving along the Y-axis, and facilitating the selection and installation of each power mechanism in each material taking driving mechanism.

[0059] The embodiment of the present invention also provides a damping strip pasting system (not shown, refer to Figures 1 to 9 ), which is used to paste the damping strip on the chip. Since the damping strip on the chip is very tiny, the accuracy of its position is very important. The damping strip system of this embodiment includes the labeling device in any of the above embodiments. The labeling device is used to paste the damping strip on the label tape with the damping strip on the chip to be pasted with the damping strip. Among them, the label conveying device 210 is used to convey and position the damping strip label tape, so that the labeling mechanism 260 can take materials at the set position. The labeling mechanism 260 moves the material taking head 261 to the top label device of the label conveying device 210 through the material taking head driving mechanism, obtains the damping strip corresponding to the position of the top label head 241, and then transports it to the chip to be pasted with the damping strip for labeling, effectively ensuring the accuracy of the damping strip pasting position and the consistency of the damping strip pasting position of the chip, thereby being beneficial to improving the production efficiency.

Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the gist of the present invention.
