Description

Technical Field

[0001] This invention relates to the field of labeling mechanism technology, specifically to an automatic alignment type high-precision labeling mechanical structure for electronic components. Background Technology

[0002] In the automated labeling process of electronic components, the labeling head is the core execution component of the labeling equipment. It is used to adsorb and transfer the label to the surface of the workpiece to be labeled. Existing labeling heads usually have multiple air holes on their bonding surface. The air holes are connected to an external air source to achieve vacuum adsorption of the label. During labeling, the labeling head adsorbs the label and moves it above the workpiece. Then, the label is attached to the surface of the workpiece by blowing air or mechanical pressing.

[0003] However, the existing labeling heads still have the following shortcomings. For example, the air holes of the existing labeling heads are mostly evenly distributed or only a combination of straight air holes and oblique air holes are set. When the label is blown on, the label is subjected to relatively uniform force, which can easily cause the entire label to contact the workpiece surface at the same time, causing air to be trapped between the label and the workpiece and forming air bubbles. This is especially true in the central area of ​​the label, where the air is most difficult to escape due to the longest exhaust path. The problem of central air bubbles is particularly prominent. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic alignment high-precision labeling mechanical structure for electronic components, in order to solve the problem mentioned in the background art where, during label application, the label adheres entirely to the surface of the workpiece, resulting in internal air not being able to escape and causing air bubbles to appear inside the label.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An automatic alignment type high-precision labeling mechanical structure for electronic components includes an assembly shell. The inner wall of one side of the assembly shell has a plurality of working holes of different sizes, the diameter of which gradually decreases from the middle to both sides. The inner wall of one side of the assembly shell has a penetration groove and an anti-collision groove. A roller pressure exhaust mechanism is provided on one side of the assembly shell. The roller pressure exhaust mechanism is connected to an external drive end and is used to perform rolling exhaust treatment on the label.

[0006] Furthermore, the roller pressing exhaust mechanism includes a housing, which is fixedly connected to one end of the assembly housing, and a movable plate is slidably connected inside the housing. One end of the movable plate is fixedly connected to two mounting brackets, each of which is rotatably equipped with a rotating shaft. Each of the two rotating shafts is fitted with a swing arm on its circumferential surface, and an exhaust roller is rotatably mounted on one end of each swing arm.

[0007] Furthermore, one end of the assembly shell is provided with multiple compensation holes, and both the upper and lower ends of the assembly shell are provided with air guide grooves. Two of the air guide grooves penetrate the inner circumference of the multiple compensation holes, and both air guide grooves are connected to an external air source. The multiple compensation holes and some of the working holes form an airflow compensation zone around the central area of ​​the inner wall of one side of the assembly shell.

[0008] Furthermore, multiple vent holes are provided at both the upper and lower ends of the assembly shell.

[0009] Furthermore, one end of the assembly shell is provided with a plurality of expansion holes, which are respectively connected to some of the working holes, and each of the plurality of expansion holes is provided with a conical groove. The inner circumferential wall of each of the plurality of expansion holes is provided with a transmission groove, which is located inside the assembly shell. The inner walls on both sides of the assembly shell are provided with a plurality of cleaning holes, which are respectively connected to the plurality of transmission grooves.

[0010] Furthermore, one end of the assembly shell is fixedly connected to two gas collection shells, both of which are connected to an external gas source and are connected to multiple working holes.

[0011] Furthermore, two torsion springs are fitted on the circumferential surfaces of the two rotating shafts, and the two ends of the plurality of rotating shafts are respectively fixedly connected to the upper and lower ends of the mounting frame and the upper and lower inner walls of the swing arm.

[0012] Furthermore, each of the two rotating shafts has a follower block fixedly connected to its circumferential surface, and one end of the moving plate has two blocking blocks fixedly connected to it, with the two blocking blocks abutting against the two follower blocks respectively.

[0013] Furthermore, one end of the housing is provided with a connection port, through which the moving plate and the piston end of the external cylinder can be connected. The external cylinder should be connected to the same gas source as the gas in the expansion hole.

[0014] Furthermore, the airflow direction of the plurality of cleaning holes is inclined relative to the inner wall of the assembly housing.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. During labeling, the label is adsorbed onto the inner wall of the assembly shell by negative pressure. The robot moves it to the workpiece position and injects air into the working hole. The large hole in the middle and the small holes on both sides make the label arched. The middle part contacts the workpiece first, and the gas is discharged from both sides to prevent air bubbles. The cylinder pushes the moving plate, and the exhaust roller enters the assembly shell through the receiving shell. After it comes into contact with the label, it rotates in the opposite direction to smooth the sides, squeeze out the residual gas and store energy in the torsion spring. After completion, the cylinder resets and the torsion spring releases the force to return the exhaust roller to the initial position.

[0016] 2. When the two exhaust rollers rotate in opposite directions around the pivot point connecting the rotating shaft and the mounting bracket, the torsion spring is twisted during this process to accumulate force. After labeling is completed, the cylinder is charged in the reverse direction, causing its piston end to pull back and gradually pull the moving plate and the corresponding workpiece back into the storage shell. As the moving plate resets, the exhaust rollers no longer contact the workpiece. At this time, the elastic force accumulated by the torsion spring rebounds and drives the two swing arms and the two exhaust rollers to reset to their initial positions, making it convenient to pull the moving plate, the two exhaust rollers, and other components of the roller pressing exhaust mechanism back into the storage shell for subsequent secondary use.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Example: An automatic alignment high-precision labeling mechanical structure for electronic components, such as Figures 1-8 As shown, the assembly includes an assembly shell 1, which is an integral frame with pre-drilled mounting holes for connection to an external robotic arm or other moving device. Several working holes 2 of varying sizes are formed on one inner wall of the assembly shell 1, with the diameter of the holes gradually decreasing from the center to both sides. A penetration groove 3 and an anti-collision groove 4 are formed on one inner wall of the assembly shell 1. An exhaust roller 8 and the penetration groove 3 fit together, and the anti-collision groove 4 and the moving plate 5 fit together, preventing collisions between the exhaust roller 8 and the moving plate 5 and one end of the assembly shell 1 during movement. A roller-pressing exhaust mechanism is provided on one side of the assembly shell 1, connected to an external drive end, for rolling exhaust treatment of the label.

[0023] The roller extrusion mechanism includes a housing 20, which forms a frame. The housing 20 is fixedly connected to one end of the assembly housing 1, and a movable plate 5 is slidably connected inside the housing 20. Two mounting brackets 6 are fixedly connected to one end of the movable plate 5. A rotating shaft 10 is rotatably mounted on each of the two mounting brackets 6. A swing arm 7 is sleeved on the circumferential surface of each of the two rotating shafts 10. An extrusion roller 8 is rotatably mounted on one end of each of the two swing arms 7. The two swing arms 7 rotate in opposite directions.

[0024] One end of the housing 20 has a connection port, through which the moving plate 5 and the piston end of the external cylinder can be connected. The external cylinder should be connected to the same gas source as the gas in the expansion hole 17.

[0025] In a specific embodiment of the present invention, when it is necessary to label electronic components, the label is first placed on a workbench, which should be convex and able to match the internal space of the assembly shell 1. Then, by connecting multiple working holes 2 to an external air source, the label is adsorbed onto the inner wall of one side of the assembly shell 1 by generating negative pressure through air extraction. The assembly shell 1 is then moved to the position of the workpiece to be labeled using a robotic arm, and is placed against the labeling position. An external air source is then activated to simultaneously inject air into multiple working holes 2. Because the diameter of the working holes 2 in the middle of the inner wall near the assembly shell 1 is larger, while the diameters on the sides are smaller, the label will briefly form an "arch" shape when inflated. For details, please refer to [link to documentation]. Figure 8 At this point, the middle part of the label will contact the workpiece first, while the sides of the label have not yet directly contacted the workpiece. Therefore, any gas that may remain in the middle of the label can be discharged through the gaps on both sides, preventing gas residue in the middle. When the external air source is injected into the working hole 2, the external air source is simultaneously injected into the external cylinder. The piston end of the external cylinder begins to move and pushes the moving plate 5 and its associated components to the labeling position. This movement is mainly divided into two stages. In the first stage, the two exhaust rollers 8 and the moving plate 5 gradually enter the assembly shell 1 from the storage shell 20, passing through the anti-collision groove 4 and the two penetration grooves 3 as channels. In the second stage, when the two exhaust rollers 8 abut against the label and the workpiece, the moving plate 5 is continuously abutted by the piston end of the cylinder, which causes the two exhaust rollers 8 to rotate in opposite directions around the axis connecting the rotating shaft 10 and the mounting bracket 6. During this process, the torsion spring 9 is twisted to accumulate force, ready for subsequent reset, and gradually smooths out the raised sides of the label, making the label fit the surface of the workpiece better, and squeezing out any residual gas on the sides of the label. After labeling is completed, the cylinder is charged in reverse, causing its piston end to pull back and gradually pull the moving plate 5 and the corresponding workpiece back into the storage shell 20. As the moving plate 5 moves back to its original position, the exhaust roller 8 no longer touches the workpiece. At this time, the elastic force stored in the torsion spring 9 rebounds and drives the two swing arms 7 and the two exhaust rollers 8 back to their initial positions, making it convenient to pull the moving plate 5, the two exhaust rollers 8 and other components of the roller extrusion mechanism back into the storage shell 20 for subsequent secondary use. The above design allows the label to be applied in a way that is not a whole piece. Instead, the middle part of the label is pasted first, while the two sides of the label are raised to leave a channel for the gas in the middle to be discharged. Then, the label is further degassed and bonded by a roller degassing mechanism. This effectively prevents or reduces the occurrence of residual air bubbles inside the label due to residual gas in the middle of the label, thereby improving the adhesive strength and aesthetics of the label. Furthermore, this structure also solves the blind spot in the existing technology of roller-type exhaust bonding. The main blind spot is that even when the two rollers are close together, because the rollers are cylindrical, there will be a certain blind area in the middle when the two cylinders are close together. This blind area cannot be pressed by the rollers, which leads to the gas in the blind area being unable to be discharged or having difficulty being discharged. In this solution, in order to address this blind spot, a design is adopted to first bond the middle position of the label and then bond the sides, which can solve the problem of gas residue in the blind area and reduce or prevent the occurrence of gas residue.

[0026] Please refer to the details. Figure 1-8 Multiple compensation holes 13 are provided at one end of the assembly shell 1. Air guide grooves 14 are provided at both the upper and lower ends of the assembly shell 1. Two air guide grooves 14 penetrate the inner circumference of the multiple compensation holes 13 and both air guide grooves 14 are connected to an external air source. Multiple compensation holes 13 and some of the working holes 2 form an airflow compensation zone around the central area of ​​the inner wall of one side of the assembly shell 1. Multiple exhaust holes 15 are provided at both the upper and lower ends of the assembly shell 1.

[0027] In this embodiment: the multiple compensation holes 13 are supplementary air holes, and the air guide groove 14 is connected to an external air source for receiving external air and then transmitting it to the multiple compensation holes 13 respectively. Figure 2 Because the anti-collision groove 4 and two penetration grooves 3 are opened in the middle of the assembly shell 1, there is a certain air pressure loss in the middle of the inner wall of the assembly shell 1. Multiple compensation holes 13 and some working holes 2 around them form a relatively dense compensation area with air holes. Through the combined air pressure replenishment of the compensation area, the air pressure lost by the anti-collision groove 4 and penetration groove 3 can be maintained or approached the air pressure of multiple working holes 2, ensuring the stability of the label when blowing and applying the label under negative pressure. Multiple exhaust holes 15 can facilitate the discharge of gas, impurities and dust in the assembly shell 1.

[0028] Preferably, in actual use, a miniature one-way valve can be installed in each of the multiple exhaust holes 15 to prevent external dust from entering the assembly housing 1 and causing contamination.

[0029] Please refer to the details. Figure 1-8 The assembly shell 1 has multiple expansion holes 17 at one end, which are connected to some of the working holes 2. Each expansion hole 17 has a conical groove 18 inside. The diameter of the expansion holes 17 connected to some of the working holes 2 is larger than that of the working hole 2 with the largest diameter in the middle. Each expansion hole 17 has a transmission groove 19 on its inner circumference. The transmission grooves 19 are located inside the assembly shell 1. Each of the inner walls on both sides of the assembly shell 1 has multiple cleaning holes 16, which are connected to the transmission grooves 19. Two gas collection shells are fixedly connected to one end of the assembly shell 1. Both gas collection shells are connected to an external gas source and are connected to the multiple working holes 2.

[0030] In this embodiment: through the gas concentration shell, the external gas source can be injected into the gas concentration shell first, and then concentrated and transmitted to multiple working holes 2. When the external gas source is injected into the two outermost rows of working holes 2 inside the assembly shell 1, the gas will first enter the expansion hole 17. When the airflow enters the multiple working holes 2 on both sides through the expansion hole 17, the gas will collide with the conical groove 18, and the airflow will be hindered by the gradually decreasing diameter of the conical groove 18. At this time, part of the airflow enters the cleaning hole 16 through the transmission groove 19 and forms an auxiliary cleaning airflow. The auxiliary cleaning airflow has a faster flow rate and can clean the dust and impurities on the workpiece position before the label is pasted. This further prevents the label from occupying space when it is pasted. In addition, the airflow sprayed from the two cleaning holes 16 can also affect the label in the opposite direction, preventing the sides of the label from sticking to the workpiece quickly and further solidifying the label so that it does not form an arch when it is pasted.

[0031] Please refer to the details. Figure 1-8 Two torsion springs 9 are fitted on the circumferential surfaces of the two rotating shafts 10. The two ends of the multiple rotating shafts 10 are fixedly connected to the upper and lower ends of the mounting frame 6 and the upper and lower inner walls of the swing arm 7, respectively. Follower blocks 12 are fixedly connected to the circumferential surfaces of the two rotating shafts 10. Two blocking blocks 11 are fixedly connected to one end of the moving plate 5. The two blocking blocks 11 abut against the two follower blocks 12, respectively.

[0032] In this embodiment: when the two exhaust rollers 8 rotate in opposite directions around the axis connecting the rotating shaft 10 and the mounting bracket 6, the torsion spring 9 is twisted during this process to accumulate force. After the labeling is completed, the cylinder is charged in the reverse direction, causing its piston end to pull back and gradually pull the moving plate 5 and the corresponding workpiece back into the storage shell 20. As the moving plate 5 moves back to its original position, the exhaust rollers 8 no longer come into contact with the workpiece. At this time, the elastic force accumulated by the torsion spring 9 rebounds and drives the two swing arms 7 and the two exhaust rollers 8 to return to their initial positions. It is convenient to pull the moving plate 5, the two exhaust rollers 8 and other components of the roller extrusion mechanism back into the storage shell 20 for subsequent secondary use. When the two swing arms 7 and the rotating shaft 10 rotate in opposite directions to reset, they will drive the two following blocks 12 to rotate synchronously. Through the blocking of the two blocking blocks 11, the excessive rotation of the rotating shaft 10 can be effectively prevented.

[0033] Please refer to the details. Figure 1-8 The air blowing direction of the multiple cleaning holes 16 is set at an angle relative to the inner wall of the assembly shell 1.

[0034] In this embodiment, the inclined airflow through multiple cleaning holes 16 creates a horizontal shearing force on the workpiece surface, effectively removing dust particles with electrostatic adsorption or slight adhesion, thus improving the thoroughness of cleaning.

[0035] Working principle: When it is necessary to label electronic components, the label is first placed on the worktable. The worktable should be convex and able to match the internal space of the assembly shell 1. Then, by connecting multiple working holes 2 to an external air source, the label is adsorbed onto the inner wall of one side of the assembly shell 1 by generating negative pressure through air extraction. The assembly shell 1 is then moved to the position of the workpiece to be labeled using a robotic arm, and is placed against the labeling position. An external air source is then activated to simultaneously inject air into multiple working holes 2. Because the diameter of the working holes 2 in the middle of the inner wall near the assembly shell 1 is larger, while the diameters on the sides are smaller, the label will briefly form an "arch" shape when inflated. For details, please refer to [link to documentation]. Figure 8 At this point, the middle part of the label will contact the workpiece first, while the sides of the label have not yet directly contacted the workpiece. Therefore, any gas that may remain in the middle of the label can be discharged through the gaps on both sides, preventing gas residue in the middle. When the external air source is injected into the working hole 2, the external air source is injected into the external cylinder. The piston end of the external cylinder begins to move and pushes the moving plate 5 and its components to the labeling position. This movement is mainly divided into two stages. In the first stage, the two exhaust rollers 8 and the moving plate 5 gradually enter the assembly shell 1 from the storage shell 20, passing through the anti-collision groove 4 and the two penetration grooves 3 as channels. In the second stage, when the two exhaust rollers 8 abut against the label and the workpiece, the moving plate 5 is continuously abutted by the piston end of the cylinder, which will cause the two exhaust rollers 8 to rotate in opposite directions around the axis connecting the rotating shaft 10 and the mounting bracket 6. During this process, the torsion spring 9 is twisted to accumulate force for subsequent reset and gradually smooths out the raised sides of the label, making the label fit the surface of the workpiece better and squeezing out any residual gas on the sides of the label. After labeling is completed, the cylinder is inflated in reverse, causing its piston end to pull back and gradually pull the moving plate 5 and the corresponding workpiece back into the storage shell 20. As the moving plate 5 resets, the exhaust roller 8 no longer touches the workpiece. At this time, the elastic force stored in the torsion spring 9 rebounds and drives the two swing arms 7 and the two exhaust rollers 8 back to their initial positions, making it convenient to pull the moving plate 5, the two exhaust rollers 8 and other components of the roller extrusion mechanism back into the storage shell 20 for subsequent secondary use.
