Technical Field

[0001] The present invention relates to the technical field of label - applying devices with precise positioning, and specifically to a label - applying device with precise positioning. Background Technique

[0002] Labels, as carriers of product information, are widely used in various industries. In the production and processing of printed circuit boards, label - applying devices are needed to paste labels. With the development of technology, people have gradually used label - applying machines to improve the efficiency of label pasting. After retrieval, it is found that a typical piercing and positioning device in the prior art is, for example, an automatic label - applying device with the publication number CN217836391U, which includes a bottom plate and a working panel arranged on the bottom plate, and also includes: a loading mechanism for carrying products to be labeled; a tape feeding and rewinding mechanism for releasing a tape loaded with labels and recovering the tape after removing the labels; a tension roller group for tensioning the tape during tape transportation; a label inspection mechanism for sensing the labels on the tape; a label picking mechanism for picking the labels on the tape released by the tape feeding and rewinding mechanism and pasting them on the products to be labeled; and a control mechanism for controlling the loading mechanism, the label inspection mechanism, the label picking mechanism, the tension roller group, and the tape feeding and rewinding mechanism to work.

Electric push rods are arranged inside the first lead screw and the second lead screw, and the electric push rods are connected to one ends of a first transmission shaft and a second transmission shaft through locking blocks. The first transmission shaft and the second transmission shaft are connected through a first belt drive structure. The end of the first transmission shaft away from the locking block is connected to the output end of a motor. At the same time, the first transmission shaft, the second transmission shaft, the first lead screw and the second lead screw are all connected to a vertical plate on the top of the processing table;

[0007] The switching label pasting mechanism is arranged between the first lead screw and the second lead screw, and a blanking seat and a label feeding assembly are respectively arranged on the left and right sides of the switching label pasting mechanism.

[0008] Preferably, the first positioning seat and the second positioning seat move in opposite directions, and balls are connected to the bottoms of the first positioning seat and the second positioning seat.

[0009] Preferably, a material transfer assembly is arranged inside each of the first positioning seat and the second positioning seat, and the material transfer assembly is arranged inside the deviation rectifying plate.

[0010] Preferably, the deviation rectifying plates are distributed in a rectangular array inside the first positioning seat and the second positioning seat, and the deviation rectifying plates are in pairs corresponding to each other.

[0011] Preferably, the material transfer assembly includes a mounting frame and electric rollers. The mounting frames are symmetrically arranged inside the first positioning seat and the second positioning seat. Electric rollers are installed inside the mounting frames, and the mounting frames are fixedly connected to the inner bottoms of the first positioning seat and the second positioning seat through second electric telescopic rods.

[0012] Preferably, the mounting frame is arranged corresponding to the protruding groove, and the protruding groove is opened inside the first positioning seat and the second positioning seat.

[0013] Preferably, the locking block is engaged with the first transmission shaft and the second transmission shaft, and the locking block is slidably connected inside the first lead screw and the second lead screw.

[0014] Preferably, the switching labeling mechanism includes a first rotating seat, a second belt transmission structure, a second rotating seat, a first mounting bracket, a second mounting bracket, a first hydraulic cylinder, a second hydraulic cylinder, a labeling device, a fixing bracket, a motor, and a roller. The first rotating seat is connected to the second rotating seat through the second belt transmission structure. At the same time, the bottom of the first rotating seat is connected to the output end of the motor. The tops of the first rotating seat and the second rotating seat are respectively connected to the first mounting bracket and the second mounting bracket. The first mounting bracket and the second mounting bracket are respectively fixedly connected to the fixing bracket and the labeling device through the first hydraulic cylinder and the second hydraulic cylinder. At the same time, a roller is connected to the fixing bracket.

[0015] Preferably, the rollers are evenly distributed at the bottom of the fixing bracket, and the rollers are rotatably connected to the fixing bracket.

[0016] Preferably, the balls are evenly distributed at the bottoms of the first positioning seat and the second positioning seat, and the bottoms of the balls are in contact with the upper surface of the processing table.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: for this labeler capable of precise positioning,

[0018] (1) Through the combined use of the first lead screw, the second lead screw, the first electric telescopic rod, the deviation rectifying plate, and the material transfer component, the present invention can effectively solve the problem that most existing labelers are equipped with conveyors for automatic feeding to improve the continuity of labeling. However, when using a conveyor for moving feeding, it is easy to affect the consistency of the labeling position due to the jitter of the workpiece during movement. The motor drives the first lead screw and the second lead screw to rotate under the drive of the first belt transmission structure. Thus, the first positioning seat and the second positioning seat can drive the workpiece to move to the labeling station, that is, achieve fixed-point automatic feeding, which is convenient for ensuring the accuracy of the labeling position. At the same time, the first electric telescopic rod pushes the deviation rectifying plate to push and adjust the position of the workpiece in the first positioning seat and the second positioning seat and squeeze and fix it after adjustment, which is convenient for further ensuring the consistency of labeling and improving the labeling accuracy of the device. On the other hand, when the workpiece in the first positioning seat and the second positioning seat is labeled, the second electric telescopic rod will push the material transfer component upward until the electric roller in the material transfer component jacks up the workpiece. Then, the electric roller rotates to push the workpiece on its top to the top of the blanking seat, thus completing automatic stacking, which is convenient for enriching the functionality of the device and further improving the automation level of the device;

[0019] (2) By using the electric push rod and the lock block in cooperation, the present invention can effectively solve the problem that the existing labeling device cannot use a set of driving devices to drive the first positioning seat and the second positioning seat for fixed-point feeding to alternately complete the feeding work. The electric push rod in the first lead screw and the second lead screw pushes the lock block to connect with the first transmission shaft and the second transmission shaft. Thus, under the drive of the motor, the two groups of first positioning seats and second positioning seats can move simultaneously. At the same time, when the first positioning seat or the second positioning seat does not need to move, the staff controls the corresponding electric push rod to pull the lock block inward away from the corresponding lead screw. Thus, the first positioning seat or the second positioning seat can be driven to move targeted, and then the alternate feeding is realized, which is convenient for ensuring the continuity of labeling.

[0020] (3) By switching the labeling mechanism, the present invention can effectively solve the problem that the existing labeling device has no structure for re-pressing and strengthening after labeling, resulting in the label being easily detached accidentally. The motor drives the first mounting bracket and the second mounting bracket to rotate simultaneously under the cooperation of the second belt transmission structure. Thus, the labeling device and the roller can be alternately rotated above the first positioning seat and the second positioning seat, so as to alternately label the workpieces on the first positioning seat and the second positioning seat. At the same time, the roller can roll and re-press the label after labeling to improve the labeling quality of the device. Brief Description of the Drawings

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0030] As Figure 1 , Figure 2 , Figure 5 and Figure 6 shown, support feet 2 are symmetrically arranged at the bottom of the processing table 1, and a first lead screw 3 and a second lead screw 4 are arranged on the top of the processing table 1.

[0033] In a further embodiment, the deviation rectifying plates 8 are distributed in a rectangular array inside the first positioning seat 5 and the second positioning seat 6, and the deviation rectifying plates 8 are in pairs corresponding to each other.

[0034] As Figure 1 , Figure 2 , Figure 3 and Figure 6 shown, electric push rods 11 are arranged inside both the first lead screw 3 and the second lead screw 4, and the electric push rods 11 are connected to one ends of a first transmission shaft 13 and a second transmission shaft 14 through locking blocks 12. The first transmission shaft 13 and the second transmission shaft 14 are connected through a first belt transmission structure 15, and one end of the first transmission shaft 13 away from the locking block 12 is connected to the output end of a motor 17. At the same time, the first transmission shaft 13, the second transmission shaft 14, the first lead screw 3 and the second lead screw 4 are all connected to a vertical plate 16 on the top of a processing table 1.

[0035] In a further embodiment, the locking blocks 12 are engaged with the first transmission shaft 13 and the second transmission shaft 14, and the locking blocks 12 are slidably connected inside the first lead screw 3 and the second lead screw 4.

[0036] As Figure 1 , Figure 2 , Figure 4 and Figure 6 shown, a switching label pasting mechanism 19 is arranged between the first lead screw 3 and the second lead screw 4, and a blanking seat 18 and a label feeding assembly 20 are respectively arranged on the left and right sides of the switching label pasting mechanism 19.

[0037] Specifically, the label feeding assembly 20 mainly conveys labels to a specified position, and it is a prior art, and the specific structure and working principle thereof will not be elaborated herein.

[0038] In a further embodiment, the switching label pasting mechanism 19 includes a first rotating seat 1901, a second belt transmission structure 1902, a second rotating seat 1903, a first mounting bracket 1904, a second mounting bracket 1905, a first hydraulic cylinder 1906, a second hydraulic cylinder 1907, a label pasting device 1908, a fixing bracket 1909, a motor 1910 and a roller 1911. The first rotating seat 1901 is connected to the second rotating seat 1903 through the second belt transmission structure 1902. At the same time, the bottom of the first rotating seat 1901 is connected to the output end of the motor 1910. The tops of the first rotating seat 1901 and the second rotating seat 1903 are respectively connected to the first mounting bracket 1904 and the second mounting bracket 1905. The first mounting bracket 1904 and the second mounting bracket 1905 are respectively fixedly connected to the fixing bracket 1909 and the label pasting device 1908 through the first hydraulic cylinder 1906 and the second hydraulic cylinder 1907. At the same time, a roller 1911 is connected to the fixing bracket 1909.

[0039] In a further embodiment, the rollers 1911 are evenly distributed at the bottom of the fixed frame 1909, and the rollers 1911 are rotatably connected to the fixed frame 1909.

[0040] In a further embodiment, the balls 21 are evenly distributed at the bottoms of the first positioning seat 5 and the second positioning seat 6, and the bottoms of the balls 21 are in contact with the upper surface of the processing table 1.

[0041] Specifically, during the actual working process, the motor 17 drives the first transmission shaft 13 to rotate. The rotating first transmission shaft 13 will drive the second transmission shaft 14 and the first lead screw 3 to rotate through the first belt transmission structure 15. At the same time, the rotating second transmission shaft 14 will drive the second lead screw 4 to rotate, so that the first positioning seat 5 and the second positioning seat 6 can move in opposite directions. The staff can place the workpiece into the first positioning seat 5 and the second positioning seat 6. Then, the first electric telescopic rods 7 on the left and right side walls push the deviation rectifying plate 8 to adjust the position of the workpiece left and right. Then, the first electric telescopic rods 7 on the front and rear side walls push the deviation rectifying plate 8 to adjust the position of the workpiece forward and backward and perform extrusion and limiting on it after the adjustment. At the same time, the first positioning seat 5 will move to the lower side of the labeling device 1908 under the drive of the motor 17.

[0042] Then, the labeling device 1908 will rotate downward in cooperation with the second hydraulic cylinder 1907 and the motor 1910 to pick up and adsorb the label on the label conveying component 20 and then attach it to the specified position of the workpiece. After the labeling is completed, the motor 17 drives the first lead screw 3 to drive the first positioning seat 5 to move in the opposite direction until it moves to one side of the first rotating seat 1901. Immediately afterwards, the electric push rod 11 in the first lead screw 3 pulls the locking block 12 inward to disengage from the first transmission shaft 13, so that the first positioning seat 5 can stop moving. The second positioning seat 6 connected to the second lead screw 4 will move to the rear side of the labeling device 1908 under the drive of the motor 17. At the same time, the motor 1910 drives the first rotating seat 1901 and the second rotating seat 1903 to move in cooperation with the second belt transmission structure 1902, so that the labeling device 1908 can be rotated above the second positioning seat 6, which is convenient for subsequent labeling of the workpiece in the second positioning seat 6.

[0043] On the other hand, the rotating first rotating seat 1901 will synchronously drive the rollers 1911 to rotate and switch to above the first positioning seat 5, so that the labels above it can be recompressed and reinforced by the rollers 1911. After the recompression and reinforcement are completed, the electric push rod 11 in the first lead screw 3 pushes the locking block 12 to reset, and the electric push rod 11 in the second lead screw 4 pulls the locking block 12 inward to disengage from the second transmission shaft 14, so that the first positioning seat 5 will move to one side of the blanking seat 18 under the drive of the motor 17. Then, the workpiece transfer component 9 conveys and transfers the workpiece to the blanking seat 18.

The electric roller 902 is installed inside the mounting frame 901, and the mounting frame 901 is fixedly connected to the inner bottom of the first positioning seat 5 and the second positioning seat 6 through the second electric telescopic rod 10.

[0047] In a further embodiment, the mounting frame 901 is correspondingly arranged with the protruding groove, and the protruding groove is opened inside the first positioning seat 5 and the second positioning seat 6.

[0048] Specifically, after the labeling and re-pressing processes are completed inside the first positioning seat 5 or the second positioning seat 6, the second electric telescopic rod 10 pushes the mounting frame 901 and the electric roller 902 upward, so that the workpiece can be jacked up from the first positioning seat 5 or the second positioning seat 6 by the electric roller 902. Then, the rotating electric roller 902 drives the workpiece to move towards the blanking seat 18, so that the workpiece can be stacked on the blanking seat 18.
