DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0027] Embodiment one, please refer to Figures 1-11This invention provides a technical solution: an automatic nameplate labeling device with adjustment function, including a support frame 1 and a first conveyor belt 2 installed on its upper rear side. The first conveyor belt 2 is connected to the support frame 1 via a slide table. A second conveyor belt 3 is arranged parallel to the front side of the first conveyor belt 2. A guide plate 4 is connected to the upper left side of the second conveyor belt 3. The guide plates 4 are symmetrically distributed on both sides of the second conveyor belt 3. The left sides of the two sets of guide plates 4 are designed with inclined surfaces, and the left sides of the two sets of guide plates 4 are designed in a "V" shape. The first conveyor belt 2 is used to transport workpieces, while the second conveyor belt 3 is used to transport nameplates to be labeled. In use, place the workpiece to be labeled evenly on the first conveyor belt 2 with the labeling surface facing up. The position of the first conveyor belt 2 can be adjusted by the slide table to adjust the labeling position of the workpiece according to the requirements. Place the nameplate to be labeled neatly into the input end of the second conveyor belt 3 with the nameplate adsorption surface facing up. Start the second conveyor belt 3. During the conveying process, the nameplate enters the "V" shaped area formed by the two sets of guide plates 4. The offset is automatically corrected along the slope and conveyed to the picking station in a centered position.

[0028] The support frame 1 is connected to a positioning tube 5, and a support tube 6 runs through the middle of the positioning tube 5. The upper end of the support tube 6 is connected to a transmission plate 7. One end of the transmission plate 7 is connected to a dispensing head 8, and the other end of the transmission plate 7 is connected to a movable block 13. The lower end of the movable block 13 is connected to a suction cup 14. The upper end of the limiting block 23 contacts the limiting rod 24, and the shape of the limiting block 23 matches that of the limiting groove 25. A protective box 20 is fixed at the lower end of the middle of the support frame 1. A first electric push rod 21 is set inside the protective box 20. The upper end of the first electric push rod 21 is connected to a transmission connecting rod 22. The lower end of the support tube 6 runs through the support frame 1 and extends into the protective box 20. The lower end of the support tube 6 is connected to the transmission connecting rod 22. A power motor 27 is fixed inside the protective box 20. The upper shaft end of the power motor 27 is connected to a transmission shaft 28. A transmission sleeve 29 is fixed at the lower end of the support tube 6. The lower end of the transmission sleeve 29 is slidably connected to the transmission shaft 28. The transmission shaft 28 has a square design. The transmission plate 7 is connected to a dispensing head 8 and a suction cup 14 at both ends, respectively. The dispensing head 8 and the suction cup 14 correspond to the first conveyor belt 2 and the second conveyor belt 3, respectively. The control system activates the first electric push rod 21 inside the protective box 20 to retract, driving the transmission plate 7 to descend, so that the suction cup 14 contacts and adsorbs the nameplate. At the same time, as the dispensing head 8 descends, glue is simultaneously dripped onto the nameplate attachment point on the workpiece. After the operation is completed, the first electric push rod 21 extends upward and pushes the transmission plate 7, dispensing head 8, and suction cup 14 to return to their original positions. The system controls the power motor 27 to drive the transmission shaft 28 to rotate. The transmission shaft 28 drives the transmission sleeve 29, support tube 6, and transmission plate 7 to rotate, switching the positions of the dispensing head 8 and the suction cup 14. The system then controls the transmission plate 7 to descend again to unload the nameplate, so that the nameplate falls onto the workpiece at the glue dripping position, completing the nameplate attachment.

[0029] A glue storage tank 9 is installed at the upper middle part of the transmission plate 7. The lower end of the glue storage tank 9 is connected to a press pump head 10. The liquid outlet end of the press pump head 10 is connected to a hose 11. A first conduit 12 is connected between the hose 11 and the dispensing head 8. A positioning rod 17 is installed inside the support tube 6. The two ends of the positioning rod 17 are connected to guide shafts. Guide grooves 19 are opened on both sides of the support tube 6. The guide shafts extend through the guide grooves 19 to the outside of the support tube 6 and are connected to the inner wall of the positioning tube 5. The guide shafts and guide grooves 19 are in sliding fit. The positioning tube 5 is rotatably connected to the support frame 1. The positioning tube 5 and the support tube 6 are in sliding fit. The lower end of the glue storage tank 9 is engaged with the transmission plate 7. The lower end of the glue storage tank 9 is threadedly connected to the press pump head 10. The press pump head 10 is fixed to the top of the support tube 6. A micro motor is installed at the upper end of the positioning rod 17. A limit block 23 is fixed at the shaft end of the micro motor. A limit rod 24 is fixed at the lower end of the press pump head 10. A semi-circular limit groove 25 is opened at the lower end of the limit rod 24. When the dispensing head 8 is above the first conveyor belt 2 and moves downward, the relative positions of the positioning tube 5 and the support tube 6 change, and the pressing pump head 10 and the limiting rod 24 connected to its lower end move downward synchronously. The limiting rod 24 contacts the limiting block 23 and, as it continues to move downward, presses the pressing pump head 10. When it returns to its upward position, it can draw the glue from the glue storage tank 9 and deliver it from the liquid outlet of the pressing pump head 10 to the inside of the hose 11. The hose 11 further delivers the glue to the first conduit 12 and then flows out from the dispensing head 8 to the nameplate pre-pasting position. When the dispensing head 8 is above the second conveyor belt 3, it descends without dispensing. After the dispensing head 8 and the suction cup 14 switch positions, the micro motor can be started, controlling the limiting block 23 to rotate and return to its initial position. At this time, when the limiting rod 24 moves downward, the limiting block 23 can engage inside the limiting groove 25, which can prevent pressure from being applied to the pressing pump head 10 and prevent glue from dripping from the dispensing head 8 above the second conveyor belt 3.

[0030] The lower end of the positioning rod 17 is connected to the piston 18, the middle part of the piston 18 is connected to the second conduit 15, and the end of the second conduit 15 is connected to the suction cup 14; the movable block 13 is slidably connected to the transmission plate 7, the upper ends of both sides of the movable block 13 are connected to the spring pieces 16, the upper ends of the spring pieces 16 are connected to the inner wall of the transmission plate 7, the second conduit 15 passes through the upper end of the movable block 13, and the second conduit 15 is slidably engaged with the movable block 13; the second conduit 15 passes through the middle of the piston 18, and a one-way valve is connected to a section of the second conduit 15 that passes through the piston 18, the piston 18 is adapted to the inner wall of the support tube 6, the middle part of the second conduit 15 is connected to the pressure relief valve 26, the valve stem of the pressure relief valve 26 extends into the limit groove 25, the upper end of the limit block 23 is designed with a slope, and the upper end of the limit block 23 is in contact with the valve stem of the pressure relief valve 26. As the suction cup 14 descends above the second conveyor belt 3, the first electric push rod 21 drives the support tube 6 downwards, causing a change in the relative position between the support tube 6 and the positioning tube 5, and a change in the position between the piston 18 and the bottom of the support tube 6, resulting in a suction action. Since the lower end of the second conduit 15 passes through the piston 18, when the piston 18 performs the suction action, air from the port of the suction cup 14 can be drawn into the lower end of the support tube 6 using the second conduit 15. After the suction cup 14 descends and contacts the nameplate, it generates suction to adsorb the nameplate. The suction cup 14 continues to descend after contacting the nameplate, compressing the spring 16 during descent to prevent obstruction. As it continues to descend, the suction gradually increases, enhancing the adsorption stability during the nameplate transfer and attachment process. After the nameplate is adsorbed, the suction cup 14 and other structures return to their original position. Due to the one-way valve design, changes in negative pressure during the return process prevent the nameplate from falling off. After the nameplate is adsorbed, the rotating transmission plate 7 switches the positions of the dispensing head 8 and the suction cup 14. The suction cup 14 rotates to above the first conveyor belt 2, at which point the workpiece dispensing is complete. The suction cup 14 is then lowered again. During the descent, a micro motor first controls the limit block 23 to reset, allowing it to engage inside the limit groove 25 and gradually squeeze the valve stem of the pressure relief valve 26, achieving negative pressure relief. Once the suction cup 14 reaches the set height, the pressure relief valve 26 is fully open, allowing external air to enter the second conduit 15. At this point, the suction cup 14 is no longer under negative pressure, releasing the adsorption of the nameplate and allowing it to adhere to the workpiece surface. During the descent, the suction cup 14 gradually compresses the spring 16, which in turn applies downward pressure to the movable block 13, ensuring stable nameplate adhesion and preventing tilting due to adhesive residue. During the feeding process of suction cup 14, the piston 18 will draw air again. The design of pressure relief valve 26 allows air to be introduced simultaneously during the nameplate feeding process, avoiding damage to the suction cup 14 or piston 18 structure caused by excessive negative pressure. At the same time, the air intake rate of pressure relief valve 26 is slightly less than the air extraction speed of piston 18, which can protect the relevant parts while the negative pressure value changes slightly.

[0031] Example 2, please refer to Figure 12This invention provides a technical solution in which a support frame 30 is installed on the right side of the first conveyor belt 2, and a second electric push rod 31 is installed in the middle of the support frame 30. The second electric push rod 31 is symmetrically arranged on both sides of the support frame 30, and the lower end of the second electric push rod 31 is connected to a pressure plate 32. This structure can achieve pressure on the nameplate. After the nameplate is attached to the surface of the workpiece, pressure can be applied to improve the stability of the nameplate attachment. Since the adhesive is usually dripped, it cannot cover a large area of ​​the nameplate. By applying downward pressure to the pressure plate 32 through the second electric push rod 31, the nameplate and the workpiece are controlled to squeeze the adhesive dripped in the middle. The adhesive will flow to the surrounding area under the squeezing force, thereby achieving a larger area coverage and improving the reliability and stability of subsequent attachment.
