Figure 2 for Figure 1 A top view of Figure 1 , 2 The labeling system is provided with a plurality of workstations, including a loading station 10, a labeling station 20 and a unloading station 40. The labeling system of this embodiment includes a loading device 100, a labeling device 200, a circulation device 500 and a positioning device 600. The positioning device 600 is arranged on the circulation device 500 and is used to position the material to be labeled. The loading device 100 is used to load the material to be labeled onto the positioning device 600. The circulation device 500 is used to drive the positioning device 600 to circulate between the various workstations for performing corresponding operations. The labeling device 200 is used to label the material on the positioning device 600 located at the labeling workstation. The positioning device 600, the loading device 100 and the labeling device 200 are arranged at the corresponding workstations in a set order, and the material is circulated between the various workstations through the circulation device 500, so as to realize continuous mechanized labeling operation. The circulation here means that it can be transported to each workstation and can be paused at the corresponding workstation for performing related operations.

[0058] The loading device 100 is arranged at the loading position 10 , and includes a material taking device 170 and a material feeding device. The material feeding device is used to deliver materials to the loading position 10 , and the material taking device 170 can hold the materials at the loading position 10 and place them on the positioning device 600 .

[0059] The labeling device 200 is arranged at the labeling position 20, and includes a label conveying device and a labeling mechanism. The label conveying device includes a conveying device and a top labeling device. The conveying device is used to convey the label tape; the top labeling device includes a carrying platform and a top labeling mechanism, and the conveying device makes the label tape spread on the carrying platform; the top labeling mechanism includes a top labeling head and a top labeling head adjustment mechanism for driving the top labeling head to move. A through hole for the top labeling head to pass through is provided on the carrying platform, and the top labeling head is configured as follows: the top labeling head can support the label at the corresponding through hole from the back of the label tape through the through hole; the labeling mechanism includes a material picking head and a material picking head driving mechanism, and the material picking head driving mechanism is configured to drive the material picking head to move to the corresponding top label head to pick up the material, and move to the product to be labeled to label.

[0060] The circulation device 500 is used to circulate the positioning device 600 between the loading position 10 , the labeling position 20 and the unloading position 40 .

[0061] Through the labeling system of the above embodiment, the loading and circulation of materials to be labeled are realized, and the labels on the label tape can be transported to the positions corresponding to the through holes. The labels at the through hole positions can be held by the top label mechanism, and the materials can be picked up and labeled by the labeling mechanism, which helps to improve the labeling accuracy, thereby meeting the labeling needs of some products with higher label position accuracy, and is suitable for the removal and labeling of micro labels.

[0062] Figure 3 is a schematic diagram of the structure of an embodiment of the circulation device, and also refers to Figure 2 , 3 The circulation device 500 includes a turntable 510 and a turntable driving device 520. The turntable 510 is provided with a plurality of positioning devices 600. The turntable driving device 520 can drive the turntable 510 to rotate so that the positioning devices 600 can circulate between various stations. The circulation device 500 can be implemented by using a turntable 510 and a driving device commonly used in an automated production line. After each positioning device 600 flows to the loading station 10 to clamp the material, it flows to the next station with the turntable 510. After completing the operation of each station, it flows to the unloading station for unloading, thereby realizing the continuous operation of materials in multiple stations and improving production efficiency.

[0063] In the embodiment shown in the figure, a loading position 10, a labeling position 20, a detection position 30 and a unloading position 40 are evenly arranged in a ring around the turntable 510, and a loading device 100, a labeling device 200, a detection device 300 and an unloading device 400 are respectively arranged corresponding to these four stations. Correspondingly, the number of positioning devices 600 arranged on the turntable 510 is 4, and they are evenly distributed on the turntable 510 along the center ring of the turntable 510. Therefore, when the turntable 510 rotates the positioning device 600 to the corresponding station, the positioning devices 600 at the four positions can be respectively located at the four stations, so the loading device 100, the labeling device 200, the detection device 300 and the unloading device 400 can perform corresponding operations at the same time. If the turntable 510 continues to rotate 90 degrees, the positioning devices 600 at each station can be simultaneously transported to the next station. In this embodiment, the loading position 10, the labeling position 20, the detection position 30 and the unloading position 40 are sequentially arranged counterclockwise, so the turntable 510 only needs to rotate counterclockwise to circulate the materials in the order of the process.

[0064] The inspection position 30 is provided with an inspection device 300, which is located at the next station of the labeling position and can be a visual inspection device, such as a CCD camera, etc., which inspects the labeling quality through visual recognition.

[0065] The unloading position 40 is provided with an unloading device 400, which is located at the next station of the detection position and is used to unload the material in the positioning device from the circulation device 500, so that the positioning device is idle so as to flow back to the loading position to clamp the loaded material.

[0066] The loading device 100 includes a feeding device and a taking device. Figure 4 This is a schematic diagram of the structure of an embodiment of a feeding device, refer to Figure 4 The feeding device is used to feed stackable disc-shaped or sheet-shaped materials, and can also be used to feed materials stored in a material tray. The feeding device is described below by taking an example. The feeding device includes a base 110, a silo 120, a supporting device 130, and a transfer device 140. The silo 120 is arranged on the base 110, and includes a accommodating space for stacking material trays A. The bottom of the silo 120 is provided with a first opening through which the material tray A passes. The material tray A is stacked in the accommodating space of the silo 120, and can be sent out of the silo 120 through the first opening at the bottom.

[0067] The material silo 120 is provided with a supporting device 130 on opposite sides thereof, and the supporting device 130 comprises a supporting head 131, a supporting driving device 132 and an adjusting device 133. The supporting driving device 132 is used to drive the supporting head 131 to extend into or withdraw from the accommodation space, and the supporting head 131 extending into the accommodation space can lift the material tray corresponding to the position of the supporting head 131. The adjusting device 133 can drive the supporting head 131 to move between a first position and a second position, and the second position is located above the first position.

[0068] The transfer device 140 includes a carrier 141 and a moving device 142 . The carrier 141 is used to carry the material tray sent out from the first opening; the moving device 142 is used to drive the carrier 141 to move into or out of the lower part of the silo 120 .

[0069] During loading, the supporting drive device 132 drives the supporting head 131 to extend into the storage space of the silo 120. At this time, the trays can be stacked in the silo 120, and the bottom of the tray stack is lifted by the supporting head 131. During feeding, the moving device 142 moves the carrier 141 to the bottom of the silo 120. At this time, the supporting device 130 can be moved downward by the adjusting device 133 until the lower tray can be placed on the carrier 141, and then the supporting head 131 is driven to withdraw from the storage space of the silo 120, so that the supporting device 130 moves upward to the second position, which corresponds to the position of the second layer of trays from the bottom to the top. At this time, the supporting head 131 is extended into the storage space to lift the second layer of trays. Therefore, the trays at the bottom can be sent out of the bottom of the silo 120 with the movement of the carrier 141, and the trays currently lifted by the supporting head 131 become the bottom trays of the tray stack. When feeding next time, the carrier 141 is moved to the bottom of the material bin 120, and the above feeding operation is repeated to realize continuous tray feeding.

[0070] In the above embodiment, the carrier 141 can also be set as a liftable structure. It only needs to add a lifting power device, such as a cylinder, to realize the lifting of the carrier 141. After the carrier 141 is moved to the bottom of the silo 120, the carrier 141 can be raised to the bottom material tray for receiving, and then the supporting device 130 is moved upward to lift the second layer of material trays. The carrier 141 is lowered to a set height, and then the silo 120 is removed by the moving device 142. The lifting carrier 141 can avoid interference during the movement. It is suitable for the situation where there are positioning devices 600 (such as the matching positioning of positioning holes and positioning pins) between the material trays and they cannot be directly translated relative to each other in the horizontal plane. It is necessary to move the bottom material tray downward to the limit position that is out of the positioning device 600 before moving.

[0071] To facilitate the lifting of the supporting head 131, lifting platforms can be set on both sides of the material tray. After the supporting head is placed against both sides of the material tray, the material tray can be pressed against the top of the supporting head through the lifting platform to achieve lifting.

A plurality of supporting heads 131 and corresponding supporting driving devices 132 can be arranged on the supporting bracket 134, and the moving supporting bracket 134 can simultaneously move the position of the supporting head 131 arranged on the supporting bracket 134. Figure 4 In the embodiment shown, two supporting heads 131 are respectively arranged on both sides of the silo 120, and there is a gap between the supporting heads 131 on the same side, so that the four supporting heads 131 can simultaneously support the material tray from both sides of the silo 120, which can ensure the stability of the support. Among them, the supporting drive device 132 can adopt a conventional telescopic cylinder, and the telescopic movement of the cylinder drives the supporting heads 131 to extend into or out of the accommodation space of the silo 120.

[0073] The silo 120 can be configured to include two side panels 121 arranged opposite to each other, which can position the sides of the tray stack to prevent the tray stack from tilting or collapsing. Each side panel 121 is provided with a second opening 122 for the support head 131 to pass through, and the support head 131 can pass through the second opening 122 in both the first position and the second position. Of course, in the specific implementation, the silo 120 can also be configured as a hollow frame structure, or a positioning column is respectively provided at the four corners of the tray, as long as the tray stacking and the side positioning of the tray stack can be achieved.

[0075] After loading is completed, the supporting head 131 can be extended into the accommodation space at the first position, the carrier 141 can be moved to the bottom of the silo 120, and then the supporting table can be raised to fit with the bottom of the bottom material tray, and then the supporting head 131 can be withdrawn from the accommodation space. At this time, the supporting table receives the material pile, and then the supporting head 131 is moved upward to the second position and extended into the accommodation space to position and lift the second layer of material tray.

[0076] The driving device can select a telescopic cylinder as needed to realize the lifting and lowering of the receiving platform 151. The carrier 141 is provided with an avoidance position 144 for the receiving platform 151 to lift and pass.

When the tray continues to rise until the supporting platform 163 is out of contact with the tray, the supporting platform 163 rotates back to its original position under the action of its own gravity, and one end of the supporting platform 163 returns to the material receiving bin 161 and is restricted from rotation by the limit device. At this time, the tray is lowered to the point where it can be lifted by the supporting platform 163 by lowering the lifting material receiving table 162, and the tray is separated from the lifting material receiving table 162, completing the closing of the tray. When the next material tray is closed, the current material tray is lifted upward by lifting the material receiving platform 162, which can push the upper material tray to move up to the bottom material tray and leave the supporting platform 163. The supporting platform 163 rotates and falls back into the material receiving bin 161, and then the material tray stack is lowered onto the supporting platform 163, and the material trays are pushed into the material receiving bin 161 in turn to achieve the stacking and closing of the material trays.

[0087] Fig.10 It is a structural schematic diagram of an embodiment of a material picking device; the loading device 100 also includes a material picking device 170, which is used to pick up materials sent from the material bin 120 of the feeding device and load them into the positioning device on the circulation device. The material picking device 170 includes a picking head 171 and a picking head driving mechanism. The picking head can adopt a conventional clamping mechanism or a vacuum suction nozzle, a suction cup, etc. to realize material holding. In this embodiment, two vacuum suction nozzles are arranged, and their position spacing corresponds to the material spacing in the material tray, so that two materials can be sucked at a time. The picking head driving mechanism includes a picking head transverse movement mechanism 172 and a picking head lifting mechanism 173. The picking head transverse movement mechanism 172 can adopt a linear motor, and the picking head lifting mechanism 173 is connected to the slide 174 of the linear motor, so that it can be driven by the picking head transverse movement mechanism 172 to realize transverse movement. The material picking head lifting mechanism 173 can be installed along the longitudinal extension direction using a telescopic cylinder to realize the lifting operation. The material picking head 171 can be installed on the telescopic rod (not shown) of the material picking head lifting mechanism through the mounting plate 175. The material picking head 171 can be moved between the feeding device and the circulation device by the transverse movement of the material picking head lifting mechanism 173 through the transverse movement of the material picking head 172. The material picking head 171 can be moved between the feeding device and the circulation device through the extension and retraction of the material picking head lifting mechanism 173. The lifting and lowering of the material picking and placing operations can be realized above the feeding device and the positioning device.

[0088] Fig.11 is a schematic structural diagram of an embodiment of a label conveying device 210, Fig.12 for Fig.11The side view shows that the label conveying device 210 of this embodiment is used to convey the label tape, including a conveying device 210 and a top label device. The conveying device 210 is used to convey the label tape along a set path. The top label device is arranged on the conveying path, and is used to hold the label on the label tape from the back of the label tape so that the subsequent process can obtain the corresponding label through the material picking device 170 for labeling.

[0089] 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 roller is 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 reel the label tape at the rear end of the conveying path. After the label tape is drawn out from the unwinding disk 213, it reaches the first conveying roller 214, and then is driven by the first driving roller 211 so that a force can be applied to the label tape so that the label tape can be unwound smoothly. A first pressing roller 215 is provided 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. Therefore, when the first driving roller 211 rotates, the label tape can be conveyed backward by friction. The first pressing roller 215 plays a role in pressing the label tape to ensure the stable conveying of the label tape.

[0090] The second conveying roller 216, the third conveying roller 217, the fourth conveying roller 218 and the fifth conveying roller 219 are also included. The second conveying roller 216 and the third conveying roller 217 are respectively arranged on both sides of the top labeling device to guide the label tape to pass through the top labeling device. The fourth conveying roller 218 and the fifth conveying roller 219 are used to guide the label tape sent from the top labeling device to the second driving roller 212 for winding.

[0091] 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. A second pressing roller 2110 is also provided next to the first driving roller 211 to press the label tape sent from the fifth conveying roller 219 to the first driving roller 211, which helps to smoothly convey the label tape and ensures that the speed of the label tape sent out from the unwinding position is consistent with the speed of the label tape sent into the winding position, thereby ensuring the smoothness of the conveying. Therefore, the rotation speed of the second driving roller 212 for winding can be consistent with 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 meets the requirement that the label tape will not be pulled between the first driving roller 211 and the second pressing roller 2110 during the winding process.

[0092] Fig.13 Schematic diagram of the structure of an embodiment of a top labeling device. Fig.14 for Fig.13 A top view of Fig.15 for Fig.14 The AA section view in the figure, Fig.16 is a schematic diagram of the structure of an embodiment of the carrying platform 220, and also refers to Fig.11 and Figures 13 to 16 The top labeling device includes a carrying platform 220, a pressing mechanism 230 and a top labeling mechanism 240. The conveying device 210 allows the label tape to be laid on the carrying platform 220. The pressing mechanism 230 includes a pressing head 231 and a pressing head lifting mechanism 232. The pressing head lifting mechanism 232 can make the pressing head 231 approach or move away from the carrying platform 220, and is used to press the label tape on the carrying platform 220. Specifically, it can be realized by a cylinder. The top labeling mechanism 240 includes a top labeling head 241 and a top labeling head adjusting mechanism 242 for driving the top labeling head 241 to move. The carrying platform 220 is provided with a through hole 221 for the top labeling head 241 to pass through. The top labeling head 241 is configured so that the top labeling head 241 can pass through the through hole 221 from the back of the label tape to abut against the label at the corresponding through hole 221. Since the carrying platform 220 is provided with conveying rollers on both sides of the front and rear sides in the conveying direction of the label tape, the surface of the label tape passing around the two conveying rollers can pass between the pressing head 231 and the carrying platform 220, and the label tape is parallel to the upper surface of the carrying platform 220. Therefore, when the material taking head in the subsequent process takes the label on the label tape, the corresponding label is lifted from the back of the label tape by the label lifting device, which can facilitate the taking of the material.

[0093] A window 2311 is provided on the pressing head 231, and the position of the window 2311 corresponds to the position of the through hole 221 on the supporting platform 220, and the edge of the window 2311 can surround the through hole 221 inside. Therefore, the pressing head 231 can form a pressing material around the window 2311 corresponding to the position of the label tape corresponding to the through hole 221, so that the label tape corresponding to the position of the through hole 221 and the label thereon can be smoothly flattened, which is convenient for material removal.

[0094] The carrying platform 220 is provided with a plurality of through holes 221, and the through holes 221 are arranged in a direction perpendicular to the conveying direction of the label tape. Therefore, the window 2311 of the pressing head 231 can press the periphery of multiple labels at one time, and pressing the material once can facilitate multiple material taking and pasting, thereby improving efficiency. The number of top label heads 241 can correspond to being equal to the number of through holes 221, or less than the number of through holes 221. If the number of top label heads 241 less than the number of through holes 221 is set, the position of the top label head 241 can be adjusted by a top label head 241 adjustment device, so that the top label head 241 can reach the position of all through holes 221 for top labeling. The top label mechanism 240 is provided with top label heads 241 corresponding to the position of each through hole 221, and a top label head 241 that can move along the arrangement direction of the through holes 221 can also be provided, so as to perform top labeling on the required through holes 221 as needed. In the illustrated embodiment, the top label device is provided with a pair of top label heads 241, and the carrying platform 220 is provided with four through holes 221 (in specific implementation, the number of through holes 221 can be reasonably set according to actual needs). The pair of top label heads 241 are installed on a top label head adjustment mechanism 242, and the top label head adjustment mechanism 242 includes a first top label head adjustment mechanism 2421 and a second top label head adjustment mechanism 2422. The first top label head adjustment mechanism 2421 can adjust the top label head 241 by lifting and lowering, and the second top label head adjustment mechanism 2422 can move the first top label head adjustment mechanism 2421 along the arrangement direction of the through holes 221, so that the top label head 241 can be moved to correspond to each through hole 221, so as to lift the label at the corresponding position. The first top label head adjustment mechanism 2421 and the second top label head adjustment mechanism 2422 can be implemented by a cylinder.

[0095] Generally speaking, the edge of the label tape carrying the label will be provided with a side hole to facilitate the positioning operation during use. In this embodiment, a positioning pin 2312 can be provided on the side of the material pressing head 231 facing the carrying platform 220. The material pressing head 231 can move toward the carrying platform 220 to insert the positioning pin 2312 into the side hole, thereby achieving the positioning of the label tape, which is helpful for accurate labeling and material removal. Accordingly, a position avoidance hole 222 can be provided on the carrying platform 220 at a position corresponding to the positioning pin 2312 to prevent the movement of the positioning pin 2312 from interfering with the carrying platform 220.

[0096] 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 that spans 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 the label tape can be positioned from both sides to ensure that the label tape is in the correct position, and avoid the label tape deviation causing the label and the through hole 221 to not correspond to each other, so that the label cannot be smoothly placed on the label and the material cannot be taken out, which affects the smooth progress of the labeling work.

[0097] In order to further ensure the position of the label tape during the conveying process and avoid the label tape from being deviated, a limit block 223 can be set in the area corresponding to the through hole 221 on the carrying platform 220. The label tape passes between the limit blocks 223, so the limit blocks 223 can be used to limit the edges of both sides of the label tape to avoid the label tape from being deviated when passing through the area with the through hole 221 on the carrying platform 220. Correspondingly, a side of the pressing head 231 facing the carrying platform 220 is provided with an avoidance position 2313 for avoiding the limit block 223. Furthermore, limit members 224 for limiting the edges of both sides of the label tape can also be set at other parts of the carrying platform 220, and these limit members 224 correspond to the positions of the above-mentioned limit blocks 223 in the conveying direction of the label tape.

[0098] Fig.16 A specific embodiment of the carrying platform 220 is shown, and the figure shows a partial structure of the back side of the carrying platform 220 of this embodiment. Corresponding to the position where the through hole 221 is set, a groove 225 is set on the back side of the carrying platform 220, and the groove 225 is connected to 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 difficulty of processing. In addition, the groove 225 can provide a moving space for the top label head 241, which helps to reduce the distance between the top label head 241 and the carrying platform 220, making the structure compact. Guide surfaces 226 are also provided on both sides of the groove 225 corresponding to each through hole 221. The two guide surfaces 226 are inclined from the side wall of the through hole 221 in the direction of the distance expansion, forming an inclined surface extending from the 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 to smoothly pass the top label head 241 into the through hole 221.

[0099] In some embodiments, the label conveying mechanism may further include a detection mechanism 250, which is disposed in front of the top labeling device and is used to detect whether there is a label on the label tape before the top labeling device removes the label. The detection mechanism 250 may use a transparent sensor, and if a certain part of the label tape becomes transparent, the detection mechanism 250 can identify that there is no label at that part.

[0100] Through the label conveying device 210 of the above embodiment, the label on the label belt can be conveyed to the set position (the position of the through hole 221), so as to facilitate the subsequent process of picking up materials and labeling at this position, which helps to improve the labeling accuracy, thereby meeting the labeling requirements of some products with high label position accuracy. And for micro-sized labels, picking up materials 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, so the present invention can be applied to the removal and labeling of micro-sized labels.

[0101] Fig.17 is a structural schematic diagram of an embodiment of a labeling device 200, Fig.18 This is a schematic diagram of the structure of an embodiment of the material taking head driving mechanism, and also refers to Fig.17 , 18 The labeling device 200 provided in this embodiment includes a labeling mechanism 260 and a label conveying device 210 of any of the above embodiments. The label conveying device 210 is used to convey the label to a set position and perform top labeling at the position through the top labeling head 241. The labeling mechanism 260 includes a material taking head 261 and a material taking head driving mechanism. The material taking head driving mechanism is configured to drive the material taking head 261 to move to the corresponding top labeling head 241 to take the material, and move to the product to be labeled to label, so as to realize the conveying, positioning, top labeling, material taking and labeling of the label, which helps to improve the labeling accuracy. The material taking head 261 can adopt a suction nozzle structure to absorb the label through the effect of vacuum adsorption, so as to remove the label from the label belt.

[0102] Specifically, the material taking 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 direction is based on the coordinate axis in the figure, where:

[0103] The material taking head 261 is connected to the third moving mechanism 264;

[0104] The first moving mechanism 262 is used to drive the second moving mechanism 263 to reciprocate along the Y axis;

[0105] The second moving mechanism 263 is used to drive the rotating mechanism 265 to reciprocate along the X-axis;

[0106] The rotating mechanism 265 is used to drive the third moving mechanism 264 to rotate around the Y axis;

[0107] The third moving mechanism 264 is used to drive the material taking head 261 to move telescopically.

[0108] The first moving mechanism 262, the second moving mechanism 263, and the third moving mechanism 264 can select cylinders or electric slides of corresponding specifications as needed, and the rotating mechanism 265 can select rotating cylinders of corresponding specifications as needed. 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 recognition. As a result, the material picking head 261 can be moved along the X and Y axis directions through the material picking head driving mechanism so as to move between the label conveying device 210 and the product to be labeled. And it can be rotated 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 extension and retraction of the material picking head 261, so that after the material picking head 261 is adjusted to the required angle through the rotating mechanism 265, the material picking head 261 is extended and retracted through the third moving mechanism 264 to achieve labeling in this direction.

[0109] Fig.19FIG. 2 is a schematic diagram of an embodiment of the first moving mechanism 262 in the material taking head driving mechanism, referring to FIG. Fig.19 The first moving mechanism 262 includes a first slide rail 2621 extending along the Y axis, a first slider 2622 slidably disposed on the first slide rail 2621, an inclined slide rail 2623 extending in an inclined direction from the rear to the front, a second slider 2624 slidably disposed on the inclined slide rail 2623, and a power element 2625 for driving the second slider 2624 to move along the X axis. 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 along the X axis direction through the power element 2625, the second moving mechanism 263 can move along the direction in which the first slide rail 2621 extends (i.e., the Y axis direction). The power element 2625 can be a mechanism in which a motor drives a lead screw to rotate. The second slider 2624 is connected to the lead screw, so that the motor drives the lead screw to rotate and drives the second slider 2624 to slide along the inclined slide rail 2623. This mechanism can set the power element 2625 in the X direction, and convert the movement output by the power element 2625 along the X-axis direction into the movement of the second moving mechanism 263 along the Y-axis direction, saving space in the Y-axis direction, which is conducive to optimizing the layout and shortening the travel of the material picking head 261 along the Y-axis, which is convenient for the selection and installation of each power mechanism in each material picking drive mechanism.

[0110] Fig. 20 is a schematic structural diagram of an embodiment of a positioning device 600, Fig.21 for Fig. 20 A top view of Fig. 22 for Fig.21 The schematic diagram of another state of the embodiment shown in FIG. Figures 20 to 22 The positioning device 600 of this embodiment includes a base body 610 and a first positioning block 620 and a second positioning block 630 disposed on the base body 610, wherein:

[0111] A positioning platform 611 is provided on the base body 610, and the positioning platform 611 includes a first side wall 612 and a second side wall 613, and a positioning angle is formed between the first side wall 612 and the second side wall 613. The first side wall 612 and the second side wall 613 can be connected and form a positioning angle at the connection, or the first side wall 612 and the second side wall 613 can have an appropriate interval, as long as it can have a positioning effect on both sides of the material.

[0112] The first positioning block 620 includes a first connecting portion 621 and a first positioning portion 622. The first positioning portion 622 is located on a side of the positioning platform 611 opposite to the first side wall 612. The first connecting portion 621 and the seat body 610 are connected by a first elastic member 623 (see Fig.24), the first elastic member 623 has an elastic force that pushes the first positioning portion 622 against the positioning platform 611. Through the action of the first elastic member 623, the first positioning portion 622 can maintain a movement tendency to approach the first side wall 612, and therefore can keep against one side of the material S placed on the positioning platform 611, and has a force that keeps the material S against the first side wall 612. In a specific implementation, the first elastic member 623 can use a compression spring, one end of the compression spring is against the first connection portion 621, and the other end is against the seat body 610, and when the compression spring is located between the first connection portion 621 and the seat body 610, it is in a compressed state, so that it can have an elastic force that pushes the first positioning portion 622 against the first side wall 612.

[0113] The second positioning block 630 includes a second connection portion 631 and a second positioning portion 632. The second positioning portion 632 is located on a side of the positioning platform 611 opposite to the second side wall 613. The second connection portion 631 is connected to the base body 610 via a second elastic member 633. The second elastic member 633 has an elastic force to push the second positioning portion 632 against the positioning platform 611. Through the action of the second elastic member 633, the second positioning portion 632 can maintain a movement trend toward the positioning platform 611, and therefore can keep against one side of the material placed on the positioning platform 611, and has a force to keep the material against the second side wall 613. Similar to the first elastic member 623, in a specific implementation, the second elastic member 633 may be a compression spring, one end of the compression spring abuts against the second connection portion 631, and the other end abuts against the seat body 610. When the compression spring is located between the second connection portion 631 and the seat body 610, it is in a compressed state, so that it can have an elastic force to abut the second positioning portion 632 against the second side wall 613. The first side wall 612, the second side wall 613, the first positioning block 620 and the second positioning block 630 form a positioning cavity for positioning the material. The material is placed in the positioning cavity, and the first positioning block 620 keeps the material against the first side wall 612, and the second positioning block 630 keeps the material against the second side wall 613, so as to achieve the positioning of the material.

[0114] refer to Fig.21 , 22 , Fig.21 The first positioning block 620 and the second positioning block 630 are shown in a state of pressing the material in the positioning platform 611. Fig. 22 The first positioning block 620 and the second positioning block 630 are shown in a state where the positioning is released. In the figure, the first positioning block 620 and the second positioning block 630 leave the positioning platform 611 and release the positioning. Fig.21The first side wall 612, the second side wall 613, the first positioning block 620 and the second positioning block 630 of the positioning device 600 of this embodiment are respectively used to abut against the four sides of the material to be positioned, so as to realize the positioning of the material placed on the positioning table 611, which is helpful for the accurate execution of the subsequent process. The positioning operation can be performed according to the following steps:

[0115] S10: Push the first positioning block 620 to make the first positioning portion 622 leave the positioning platform 611;

[0116] S20: Push the second positioning block 630 to make the second positioning portion 632 leave the positioning platform 611;

[0117] S30: placing the material on the positioning table 611;

[0118] S40: releasing the thrust of the first positioning block 620 to return the first positioning portion 622 to its original position, so that the first positioning portion 622 abuts against one side of the material and pushes the material against the first side wall 612;

[0119] S50 : releasing the thrust of the second positioning block 630 , so that the second positioning portion 632 returns to its original position, and the second positioning portion 632 abuts against one side of the material and pushes the material against the second side wall 613 .

[0120] In the above steps, S10 and S20 can be performed simultaneously, or the order of S10 and S20 can be reversed. S40 and S50 can be performed simultaneously, or the order of S40 and S50 can be reversed.

[0121] The positioning of the material can be released by performing the operations of S10 and S20.

[0122] The positioning platform 611, the first side wall 612, the second side wall 613, the first positioning block 620 and the second positioning block 630 can be used to position the material on the positioning platform 611. When the positioning needs to be released, the first positioning block 620 and the second positioning block 630 only need to be pushed away from the positioning platform 611. At this time, when placing the material on the positioning platform 611, the first positioning block 620 and the second positioning block 630 only need to be released from the thrust. The first positioning block 620 and the second positioning block 630 can return to their positions under the action of the first elastic member 623 and the second elastic member 633 respectively, and can continue to abut against the material under the action of the first elastic member 623 and the second elastic member 633 to keep the material in an accurate positioning state. There is no need to set up a power device to press the first positioning platform 611 and the second positioning platform 611, which is convenient to operate and simplifies the structural setting.

[0123] The positioning device 600 of this embodiment is suitable for positioning rectangular materials, circular materials, elliptical materials or other materials that can be positioned on four sides. In the embodiment shown in the figure, the first side wall 612 and the second side wall 613 are connected at right angles and are used to position rectangular materials. The positioning angle formed at the connection can position one corner of the rectangular material. The positioning structure is simple and the positioning is stable. The first positioning block 620 is used to abut against the side of the rectangular material opposite to the first side wall 612, and the second positioning block 630 is used to abut against the side of the rectangular material opposite to the second side wall 613. Under the action of the first positioning block 620 and the second positioning block 630, the rectangular material located on the positioning platform 611 can abut against the positioning angle, thereby realizing the positioning of the four sides of the rectangular material, which is helpful for the accurate execution of subsequent processes.

[0124] The specific structures of the base body 610, the first positioning block 620, and the second positioning block 630 in the positioning device 600 may refer to the following embodiments:

[0125] Fig.23 for Fig.21 The cross-sectional view at BB in the figure, Fig.24 for Fig.21 The CC section view in the figure also refers to Fig.21 , 23 24. In the positioning device 600 of this embodiment, a first accommodating cavity 614 is provided on the seat body 610, and a first connecting portion 621 is provided in the first accommodating cavity 614, so that the structure is stable and compact. A first positioning portion 622 is provided on the portion of the first connecting portion 621 located in the first accommodating cavity 614, and a first elastic member 623 is supported between the first positioning portion 622 and the seat body 610, so that the first elastic member 623 is installed, and the first elastic member 623 is located inside the seat body 610, so as to ensure the stability of the installation.

[0126] Based on the above embodiment, the following settings can also be performed:

[0127] refer to Fig.23 , the first accommodating cavity 614 can be set to be a side of the seat body 610 corresponding to the first side wall 612, and the first positioning block 620 can be set to have a first positioning portion 622 abut against a side of the material to be positioned under the action of the first elastic member 623, and one end of the first connecting portion 621 extends from the first accommodating cavity 614 to the outside of the seat body 610. Therefore, it is only necessary to set a pushing device on this side of the seat body 610, and the first positioning portion 622 can be moved by pushing the end of the first connecting portion 621 extending outside the seat body 610, and the thrust of pushing the first connecting portion 621 can be released. Under the action of the elastic member, the first positioning portion 622 can be returned to its original position. Compared with directly moving the first positioning portion 622, the operation is more convenient, and the material on the positioning platform 611 can be avoided from being blocked, which is not conducive to the execution of subsequent processes.

[0128] A first groove 624 for accommodating the first elastic member 623 may be provided on one side of the first connecting portion 621 toward the bottom of the first accommodating cavity 614. The groove wall of the first groove 624 can position the elastic member. The end wall of the first groove 624 toward the first accommodating cavity 614 can form the above-mentioned first positioning portion 622, which can support the first elastic member 623.

[0129] In other embodiments, the seat body 610 may be provided with a second accommodating cavity 615, and the second connecting portion 631 is disposed in the second accommodating cavity 615, so that the structure is stable and compact. The portion of the second connecting portion 631 located in the second accommodating cavity 615 is provided with a second positioning portion 632, and the second elastic member 633 is supported between the second positioning portion 632 and the seat body 610. The installation of the second elastic member 633 is realized, and the second elastic member 633 is located inside the seat body 610, which ensures the stability of the installation.

[0130] refer to Fig.24 , the second accommodating cavity 615 can be set to be a side of the seat body 610 corresponding to the second side wall 613, the second positioning portion 632 is pressed against the side of the material to be positioned under the action of the second elastic member 633, and one end of the second connecting portion 631 extends out of the seat body 610 from the second accommodating cavity 615. Therefore, similar to the setting of the first positioning block 620 mentioned above, it is only necessary to set a pushing device on this side of the seat body 610, and the second positioning portion 632 can be moved by pushing the end of the second connecting portion 631 extending out of the seat body 610, and the thrust of pushing the second connecting portion 631 can be released. Under the action of the elastic member, the second positioning portion 632 can be returned. Compared with directly moving the second positioning portion 632, the operation is more convenient, and it is avoided to block the material on the positioning platform 611, which is not conducive to the execution of subsequent processes.

[0131] The second connecting portion 631 may be provided with a second groove 634 for accommodating the second elastic member 633 on one side facing the bottom of the second accommodating cavity 615. The groove wall of the second groove 634 can position the elastic member, and the end wall of the second groove 634 facing the second accommodating cavity 615 can form the second positioning portion 632 mentioned above, which can resist the second elastic member 633.

[0132] In combination with the above embodiments, a plurality of positioning platforms 611 may be arranged on the base body 610, and the corresponding positioning platforms 611 may be respectively provided with a first side wall 612 and a second side wall 613 according to the above embodiments. The positioning device is respectively provided with a corresponding first positioning block 620 and a second positioning block 630 corresponding to each positioning platform 611. Each first positioning block and each second positioning block can be pushed by the same pushing device to move the first positioning portion and the second positioning portion away from the positioning platform, so that several pieces of materials can be positioned at the same time, and the positioning can be released by the same pushing device, thereby realizing rapid loading and unloading of materials, which helps to improve the processing efficiency of subsequent processes.

[0133] In some embodiments, a pair of positioning platforms 611 are symmetrically arranged on the seat body 610, and the positioning device is provided with a pair of first positioning blocks 620 and a pair of second positioning blocks 630. Each first positioning block 620 and each second positioning block 630 are arranged corresponding to the positioning platform 611 according to the above embodiments, so that two pieces of materials can be positioned at the same time. The second side walls 613 are parallel to each other and there is a gap between them. The gap is set so that one end of the two second connecting parts 631 extends out of the seat body 610 from the second accommodating cavity 615 without interfering with each other, ensuring that the stroke of the second positioning part 632 can press the material on the positioning platform 611. In addition, a material pushing device can extend into the gap and push the two second connecting parts 631 at the same time so that the second positioning parts 632 leave the positioning platform 611 at the same time, thereby realizing simultaneous operation on both sides, simplifying the operation steps and structural settings. The two first connection parts 621 extend from the same side of the seat body 610, and can be moved by a pushing device arranged on the side of the seat body 610, thereby simultaneously pushing the two first positioning parts 622 away from the positioning platform 611, simplifying the operation steps and structural settings.

[0134] Conventional positioning devices 600 are usually provided with a plurality of sliders and a power device for pushing the sliders to move. The material is clamped or loosened by the movement of each slider relative to the material, and the positioning or release is achieved, which is complicated to operate. In addition, multiple power devices are required to drive the sliders, and the structure is complicated. Since the power device has a predetermined specification, the device cannot be used if a relatively small material needs to be positioned. Compared with the conventional positioning device 600, the positioning device 600 of the present invention has a simple structure and reliable positioning, and is particularly suitable for positioning small materials.

[0135] Fig.25 is a schematic structural diagram of another embodiment of a positioning device 600, Fig.26 for Fig.25 A top view of Fig. 27 for Fig.26 A schematic diagram of another state of the embodiment shown; Figures 25 to 27In the positioning device 600 of this embodiment, the second accommodating cavity 615 can be set to pass through the side of the seat body 610 corresponding to the second side wall 613, the second positioning portion 632 abuts against the side of the material to be positioned under the action of the second elastic member 633, and one end of the second connecting portion 631 extends from the second accommodating cavity 615 to the outside of the seat body 610. A pair of positioning platforms 611 are symmetrically arranged on the seat body 610, and the positioning device includes a pair of first positioning blocks 620 and a pair of second positioning blocks 630. Each first positioning block 620 and each second positioning block 630 are respectively arranged on the seat body 610 in the manner of the aforementioned embodiment, so that two pieces of material can be positioned. The same pushing device can push each first positioning block 620 and each second positioning block 630, so that the first positioning portion 622 and the second positioning portion 632 are away from the positioning platform 611, so as to achieve simultaneous positioning and simultaneous release of positioning of two pieces of material. In some embodiments, the positioning device also includes an opening device 640, and the opening device 640 includes a first pushing portion 641 and a second pushing portion 642. As the opening device 640 moves, the first pushing portion 641 can push each first positioning block 620 to move, and the second pushing portion 642 can push each second positioning block 630 to move.

[0136] Similar to the above embodiments, each first positioning portion 622 is pressed against one side of the material to be positioned under the action of the first elastic member, and one end of each first connecting portion 621 extends from the outer wall of the seat body 610 in the same direction; each second positioning portion 632 is pressed against one side of the material to be positioned under the action of the second elastic member. In this embodiment, one end of each second connecting portion 631 extends from the outer wall of the seat body 610 toward each other without interfering with each other, and each second connecting portion 631 can be pushed to move at the same time by the opening device 640. Specifically, the second side walls 613 are parallel to each other and there is a gap 616 between the two. One end of the two second connecting portions 631 can extend from the outer wall of the seat body 610 to the gap relatively without interfering with each other, so as to ensure that the stroke of the second positioning portion 632 can press the material located on the positioning platform 611. The positions of the second connecting portions 631 can be relative or staggered. In this embodiment, one end of each second connecting portion 631 extending from the seat body 610 is located in the above-mentioned gap 616 and is relative. One end of the second connecting portion 631 located in the gap 616 has a first guide surface for guiding the front end of the second pushing portion 642; the second pushing portion 642 is provided with second guide surfaces corresponding to the two sides of the second connecting portion 631, and the distance between the second guide surfaces gradually decreases along the pushing direction of the second pushing portion 642, thereby forming a tip structure at the front end of the second pushing portion 642. With the pushing of the second pushing portion 642, the tip extends from between the first guide surfaces of the second connecting portion 631 into between the second connecting portions 631, and the second connecting portion 631 slides along the second guide surface and is pushed, thereby, the second pushing portion 642 simultaneously pushes the end of the second connecting portion 631 extending from the outside of the seat body 610 in the second accommodating cavity 615 to move in the opposite direction, realizing the operation of simultaneously pushing the two second connecting portions 631 so that the second positioning portion 632 simultaneously leaves the positioning platform 611, simplifying the operation steps and structural settings.

[0137] Based on the above embodiment, the opening device 640 may further include a first push portion 641, a first accommodating cavity 614 passes through a side of the seat body 610 corresponding to the first side wall 612, a first positioning block 620 is configured such that the first positioning portion 622 abuts against a side of the material to be positioned under the action of the first elastic member 623, and one end of the first connecting portion 621 extends from the first accommodating cavity 614 to the outside of the seat body 610; with the movement of the second push portion 642, the first push portion 641 can simultaneously push the first connecting portion 621 to extend from the outside of the seat body 610 to move to the inside of the first accommodating cavity 614, so that the first positioning portion 622 can simultaneously leave the positioning platform 611, simplifying the operation steps and structural settings. The driving device 643 used to drive the opening device 640 to move can select a conventional cylinder as needed. The opening device 640 is withdrawn from the gap 616 between the second side walls 613, and each first positioning block 620 and each second positioning block 630 can return to their original positions. The clamping state and the releasing state of the positioning device 600 can be achieved through the reciprocating motion of the opening device 640. The operation is convenient and there is no need to set up other power devices for clamping or releasing operations. Therefore, the structure is simple and easy to implement.

[0138] In other embodiments, the following settings may also be made: Fig.28 This is a schematic diagram of the structure of an embodiment of a positioning device, a rotating fixture and a fixture rotating device, referring to Figure 3 and Figures 25 to 28 A jig rotating device 700 can also be set at the labeling position 20 and the detection position 30. Correspondingly, a rotating jig 800 can be set at the position corresponding to the positioning device 600 on the turntable 510. The rotating jig 800 can be rotatably installed on the turntable 510.

The rotating jig 800 located at the labeling position 20 and the detection position 30 can be driven to rotate by the jig rotating device 700, so that it can be suitable for labeling and detection on two or more sides of the material.

[0139] The rotating jig 800 includes a rotating table 810, and a rotating shaft 820 is connected to the rotating table 810. The rotating jig 800 and the turntable 510 can be rotatably connected by the rotating shaft 820 and the turntable 510, for example, the rotating shaft 820 and the turntable 510 are rotatably connected by a bearing. The jig rotating device 700 includes a rotating power device 710, a clamping power device 720 and a clamping jaw 730, and the clamping jaw 730 is connected to the clamping power device 720, and the clamping power device 720 is connected to the rotating power device 710. The clamping jaw 730 is driven by the clamping power device 720 to clamp the rotating jig 800, and then the rotating power device 710 drives the clamping power device 720 to rotate to realize the rotation of the clamping jaw 730, thereby driving the jig to rotate, so that the positioning device set on the rotating table 810 can be rotated. The above-mentioned rotating power device 710 can use a rotating cylinder, and the clamping power device 720 can use a bidirectional cylinder. The clamping power device 720 is connected to the rotating output shaft of the rotating cylinder, and the clamping claws 730 are respectively connected to the sliders of the bidirectional cylinder. When labeling, one side of the material can be labeled first, and the jig can be driven to rotate by the jig rotating device 700, so as to rotate the positioning device and the material clamped by it to the set angle, and label the other side. After labeling, the labeling inspection of each side is carried out in the same way.

[0140] In some embodiments, the unloading device 400 includes a receiving device 410 and a unloading mechanism 420.

The structure of the receiving device 410 can be set to a structure that is the same or similar to the feeding device in the above-mentioned loading device, and the operating principle is the same, but the material bin of the receiving device 410 is used to transport the stacked empty material trays to the set position so that the unloading mechanism can place the material in the material tray, and the material can be collected after the material tray is filled. Similarly, the receiving device can also adopt a further improved embodiment of the feeding device mentioned above, and a closing device of the same or similar structure is set. The operating principle is the same, but the closing device of the receiving device is used to stack the material trays filled with labeled materials in the receiving bin. After the receiving bin is filled, the whole pile of labeled materials can be taken away, which is convenient for material storage and improves production efficiency.
