Description

Technical Field

[0001] This utility model relates to the field of lighter manufacturing and assembly technology, specifically to a zinc sleeve vacuum adsorption device and a zinc sleeve installation mechanism. Background Technology

[0002] In lighter assembly equipment, a gripper mechanism is used to sequentially pick up the zinc sleeve, cotton rod, cotton pad, and nozzle and place them into the oil tank. Traditional grippers for picking up the zinc sleeve generally use a tapered rod. This design achieves the gripping function by inserting the tapered rod into the zinc sleeve and relying on the interference fit between the tapered rod and the inner wall of the zinc sleeve.

[0003] However, in practical applications, this gripping method has the following drawbacks: On the one hand, due to the limited friction between the tapered rod and the inner wall of the zinc sleeve, when the gripper encounters vibration or acceleration changes during movement, the zinc sleeve is prone to detach from the tapered rod, leading to assembly failure; on the other hand, the insertion and removal process of the tapered rod can easily deform and damage the zinc sleeve, resulting in damage to the fixture, which in turn increases the scrap rate and processing costs. Utility Model Content

[0004] To solve the above problems, this utility model provides the following solution:

[0005] A zinc sleeve vacuum adsorption device includes a vacuum adsorption body, on which one or more vacuum suction tubes are provided. Each vacuum suction tube has an air intake channel, and a guide rod is provided in the air intake channel. The guide rod extends to the outside of the opening of the vacuum suction tube, and the vacuum suction tube draws the zinc sleeve along the guide rod into the air intake channel.

[0006] As a further embodiment of this utility model, the guide rod is coaxially arranged with the air intake channel, and there is a gap between the peripheral sidewall of the guide rod and the inner wall of the air intake channel.

[0007] As a further embodiment of this utility model, the guide rod includes an upper section and a lower section, the diameter of the upper section being larger than the diameter of the lower section, so that a step is formed at the connection between the upper section and the lower section, and when the vacuum suction tube picks up the zinc sleeve, the zinc sleeve fits against the step.

[0008] As a further embodiment of this utility model, the upper section is located inside the air intake channel, and the lower section extends from inside the air intake channel to the outside of the vacuum suction tube, and the lower section is used to penetrate into the zinc sleeve.

[0009] As a further embodiment of this utility model, a flared opening is provided at the end of the air intake channel, and the diameter of the flared opening gradually increases from top to bottom.

[0010] As a further embodiment of this utility model, the vacuum adsorption body includes a mounting frame, on which a mounting plate is provided, and the vacuum suction tube is fixed to the mounting plate and extends vertically to the bottom of the mounting plate.

[0011] In addition, another aspect of this utility model proposes a zinc sleeve installation mechanism, including a vibrating feeding tray and a feeding platform, as well as the aforementioned zinc sleeve vacuum adsorption device.

[0012] As a further embodiment of this utility model, a feeding plate is slidably connected to the feeding platform in the horizontal direction, the discharge port of the vibrating feeding disc faces the upper end face of the feeding plate, and a receiving groove is formed on the upper end face of the feeding plate; when the discharge port of the vibrating feeding disc is not aligned with the receiving groove, the zinc sleeve at the very end of the discharge port is in contact with the upper end face of the feeding plate; when the discharge port of the vibrating feeding disc is aligned with the receiving groove, the zinc sleeve at the very end of the discharge port falls into the receiving groove.

[0013] As a further embodiment of this utility model, a feeding detection device is provided inside the feeding plate, which is used to detect whether there is a zinc sleeve in the receiving tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The vacuum suction tube generates negative pressure, which can firmly adhere to the zinc sleeve. Even if there is a large vibration or acceleration change during the movement, it can effectively prevent the zinc sleeve from falling off, thus greatly improving the stability and success rate of assembly. The guide rod is only used to guide the zinc sleeve to move along the predetermined path and does not participate in the force transmission during the gripping process. This avoids the direct squeezing and damage to the inner wall of the zinc sleeve by the traditional tapered rod. While maintaining the installation accuracy of the zinc sleeve, it also protects the integrity of the zinc sleeve and reduces material waste.

[0016] 2. By dividing the guide rod into upper and lower sections to form a step, the zinc sleeve is restricted at the step when it is sucked into the suction channel and will not continue to move upward. The zinc sleeves of each vacuum suction tube remain aligned, improving the stability of the installation.

[0017] 3. By setting a flared mouth at the end of the suction channel, the zinc sleeve is less likely to get stuck at the opening when it is sucked into the vacuum suction tube.

[0018] These or other aspects of this application will become more apparent from the following description of embodiments. It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only, and are not intended to limit the application.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit this application.

Therefore, "first" and "second" are merely for convenience of expression and should not be construed as limiting the embodiments of this utility model. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, such as other steps or units inherent in a process, method, system, product, or device that includes a series of steps or units.

[0029] Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] First embodiment:

[0031] A zinc-clad vacuum adsorption device, such as Figure 1As shown, it includes a vacuum adsorption body 1, on which one or more vacuum suction tubes 2 are provided. The vacuum suction tube 2 has an air intake channel 3, and a guide rod 4 is provided in the air intake channel 3. The guide rod 4 extends from the air intake channel 3 to the outside of the opening of the vacuum suction tube 2. The vacuum suction tube 2 draws the zinc sleeve 15 into the air intake channel 3 along the guide rod 4.

[0032] The negative pressure suction generated by the vacuum suction tube 2 can firmly adhere to the zinc sleeve 15, effectively preventing the zinc sleeve 15 from falling off even when encountering large vibrations or acceleration changes during movement, thereby greatly improving the stability and success rate of assembly.

[0033] like Figure 2 and Figure 3 As shown, both the guide rod 4 and the air intake channel 3 are cylindrical, and the guide rod 4 and the air intake channel 3 are coaxially arranged. There is a gap between the peripheral side wall of the guide rod 4 and the inner wall of the air intake channel 3, so that the airflow can flow through the gap and avoid the air intake channel 3 being blocked.

[0034] Both the air intake channel 3 and the guide rod 4 are vertically arranged. The zinc sleeve 15 moves vertically along the guide rod 4. At the same time, the zinc sleeve 15 is fitted on the guide rod 4, which also makes it less likely for the zinc sleeve 15 to fall off due to collisions or other reasons.

[0035] The guide rod 4 includes an upper section and a lower section, which are coaxially arranged. The inner diameter of the suction channel 3 is larger than the diameter of the upper section, and the diameter of the upper section is larger than the diameter of the lower section, so that a step 5 is formed at the connection between the upper and lower sections. When the vacuum suction tube 2 picks up the zinc sleeve 15, the zinc sleeve 15 fits against the step 5. The step 5 acts as a limit, preventing the zinc sleeve 15 from moving further inward. All the zinc sleeves 15 on the vacuum suction tube 2 are aligned at the step 5.

[0036] The upper section is located inside the suction channel 3, and the lower section extends from inside the suction channel 3 to the outside of the vacuum suction tube 2. The lower section is used to insert into the zinc sleeve 15. This ensures that the step 5 is located inside the suction channel 3. When the zinc sleeve 15 is sucked up and fits against the step 5, at least the head of the zinc sleeve 15 will be located inside the suction channel 3, resulting in a more secure adhesion.

[0037] The diameter of the lower section is smaller than the inner diameter of the zinc sleeve 15. When the lower section is inserted into the zinc sleeve 15, there is a small gap between the inner wall of the zinc sleeve 15 and the peripheral wall of the lower section to prevent the zinc sleeve 15 from getting stuck when it moves. At the same time, the gap is not too large, so that the zinc sleeve 15 remains in a vertical position when it moves along the lower section. The end of the lower section is set into a conical shape, which makes it easier for the lower section to be inserted into the zinc sleeve 15.

[0038] Therefore, the guide rod 4 is only used to guide the zinc sleeve 15 to move vertically, making it less likely to fall off. It does not participate in force transmission during the gripping process, thus avoiding direct compression and damage to the inner wall of the zinc sleeve 15 by the traditional tapered rod. At the same time, compared to ordinary suction cup grippers, the guide rod 4 maintains the accuracy of the zinc sleeve 15 during installation.

[0039] A flared opening 6 is provided at the end of the air intake channel 3. The diameter of the flared opening 6 gradually increases from top to bottom, and the top of the flared opening 6, which is the smallest in diameter, is the same as the diameter of the air intake channel 3. The flared opening 6 makes it easier for the zinc sleeve 15 to enter the opening of the vacuum suction tube 2, making it less likely to get stuck, and making the assembly process more stable.

[0040] The vacuum adsorption body 1 includes a mounting frame 101, with a mounting plate 102 fixed to the bottom of the mounting frame 101. Vacuum suction tubes 2 are fixed to the mounting plate 102 and extend vertically to the bottom of the mounting plate 102. In this embodiment, five vacuum suction tubes 2 are provided, capable of simultaneously gripping five zinc sleeves 15. The five vacuum suction tubes 2 are arranged at equal intervals along the horizontal direction on the mounting plate 102. The mounting frame 101 is connected to a drive mechanism in the lighter assembly equipment, which drives the vacuum adsorption body 1 to move within space.

[0041] Second embodiment:

[0042] A zinc sleeve mounting mechanism, such as Figure 4 As shown, the device includes a vibrating feeding tray 7 and a feeding platform 8, as well as the zinc sleeve vacuum adsorption device described in the above embodiment. The vibrating feeding tray 7 conveys the zinc sleeve 15 to the feeding platform 8, and the zinc sleeve vacuum adsorption device then grabs the zinc sleeve 15 from the feeding platform 8 and loads it into the oil tank.

[0043] like Figure 5 and Figure 6 As shown, a loading plate 10 is slidably connected to the loading platform 8 along the horizontal direction. A drive cylinder 12 is provided at the rear end of the loading platform 8. The loading plate 10 is connected to the piston rod of the drive cylinder 12. The drive cylinder 12 drives the loading plate 10 to move on the guide rail inside the loading platform 8.

[0044] The discharge port 9 of the vibrating feeding plate 7 faces the upper end face of the feeding plate 10. The end of the discharge port 9 of the vibrating feeding plate 7 is vertically downward and is in contact with or has a small gap with the upper end face of the feeding plate 10, so that the last row of zinc sleeves 15 at the end of the discharge port 9 will be in contact with the upper end face of the feeding plate 10. The upper end face of the feeding plate 10 is provided with a receiving groove 11.

[0045] When the discharge port 9 of the vibrating feed plate 7 is not aligned with the receiving groove 11, the zinc sleeve 15 at the very end of the discharge port 9 is in contact with the upper surface of the feed plate 10, preventing the zinc sleeve 15 from falling out. When the discharge port 9 of the vibrating feed plate 7 is aligned with the receiving groove 11, the zinc sleeve 15 at the very end of the discharge port 9 will fall into the receiving groove 11. Specifically, there are 5 receiving grooves, corresponding to the vacuum suction tube 2, which simultaneously supply 5 zinc sleeves 15.

[0046] After the zinc sleeve 15 falls into the receiving tank 11, the drive cylinder 12 drives the feeding plate 10 to move towards the zinc sleeve vacuum adsorption device. The zinc sleeve vacuum adsorption device grabs the zinc sleeve 15 in the receiving tank 11. Then the drive cylinder 12 drives the feeding plate 10 to move backward, so that the receiving tank 11 is aligned with the discharge port 9 again, so that the next row of zinc sleeves 15 falls into the receiving tank 11, and the cycle continues to feed.

[0047] A feeding detection device is installed inside the feeding plate 10 to detect whether there is a zinc sleeve 15 in the receiving tank 11. The feeding plate 10 has a segment 13 that communicates with the receiving tank 11. The feeding detection device uses a laser 14 detector installed in the segment 13. By emitting a laser 14 into the receiving tank 11, the presence of a zinc sleeve 15 in the receiving tank 11 is detected when the laser 14 is blocked.
