Description

Technical Field

[0001] This utility model belongs to the field of automation equipment technology, specifically relating to an automatic lead seal installation mechanism. Background Technology

[0002] A lead seal is a lock-like device used to ensure the integrity and security of goods or containers. Also known as a lead tag or clasp, it is generally a metal tag made through processes such as cutting, molding, and printing. Materials include aluminum and tin alloys, and shapes include round and special shapes. It is mainly divided into single and double lead seals. Its primary purpose is to prevent valuable items from being unauthorized opened or altered, to protect their original sealed state, and to prevent counterfeit or substandard products from entering the market. Once properly locked, a lead seal cannot be opened unless it is broken. Therefore, it is commonly used in containers, safes, and other situations requiring protection against theft and damage. Furthermore, each lead seal has a unique number, or seal number, which allows verification of whether the container or goods have been opened, thus ensuring the safety and integrity of the goods.

[0003] Figure 9 in the patent application number 201710157366.3 shows a lead seal for an electricity meter. The patent also discloses a lead seal feeding mechanism.

[0004] However, in actual production, the efficiency of a single lead seal transfer cannot meet production needs. The simplest way to improve efficiency is to install multiple feeding and unloading mechanisms. However, the corresponding lead seal transfer mechanism also needs to be optimized. Therefore, the main technology of this application is to optimize an automatic lead seal installation mechanism that is compatible with the operation of multiple feeding and unloading mechanisms. Utility Model Content

[0005] In view of the problems raised in the background art above, the purpose of this utility model is to provide an automatic lead seal installation mechanism.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] The automatic lead seal installation mechanism includes a three-axis moving mechanism and a transfer mechanism. The output end of the three-axis moving mechanism is equipped with a main cylinder, the output end of the main cylinder is connected to a secondary cylinder, the output end of the secondary cylinder is connected to a mounting frame, the mounting frame is equipped with a suction nozzle, and the power end of the suction nozzle is connected to an air pump.

[0008] The transfer mechanism includes a support frame, on which a transfer box is mounted. The transfer box has several inlets on its side, arranged horizontally. A transfer block is slidably mounted inside the transfer box. Each transfer block has a corresponding number of placement slots for each inlet, with the slots positioned to match the inlets. The transfer block is connected to a stop block with dimensions matching the inlets. A cylinder is mounted in the transfer box, with its output connected to the transfer block. A cover plate is mounted on the transfer box, with a corresponding number of laser sensors for each inlet and a corresponding number of dispensing ports. Both the transfer box and the placement slots have conductive ports positioned to correspond to the laser sensors.

[0009] Furthermore, the bracket is provided with an oblong hole, and the transfer box is installed on the bracket through the oblong hole. This design allows for a certain degree of fine adjustment of the installation height of the transfer box, thereby adapting to the feeding mechanism of different height output ends, such as the feeding docking of a vibratory feeder.

[0010] Furthermore, two top posts are installed between the transfer block and the transfer box, and the two top posts are located next to the stop block. With this design, when the cylinder malfunctions or causes overtravel, the stop block will not collide with the transfer box, thus ensuring that the stop block will not be damaged due to collision.

[0011] Furthermore, the transfer block is provided with a mating groove, the transfer box is equipped with an adjusting screw, and the end of the adjusting screw is equipped with an abutment head. The position of the abutment head corresponds to the mating groove. This design prevents overtravel while precisely adjusting the moving position of the transfer block so that its placement groove is directly opposite the material inlet.

[0012] Furthermore, some of the feed inlets are provided with a first positioning rib, and a second positioning rib is provided in the placement groove corresponding to the first positioning rib. This design is suitable for the transfer of some lead seals that need to be positioned, and the first positioning rib and the second positioning rib achieve the positioning effect.

[0013] The beneficial effects of using this utility model are as follows:

[0014] The structural design of this utility model, with its multiple inlet ports, combined with the placement groove on the transfer block and the material removal port on the cover plate, can accommodate the automatic transfer and installation of multiple lead seals, thereby improving efficiency.

[0015] With the structural design of this utility model, the transfer block can achieve the purpose of transferring materials one by one, thus realizing the effect of material distribution. Under the effect of the block, the subsequent lead seal will not enter the transfer box if the previous lead seal has not been removed, ensuring the normal operation of the cycle.

[0024] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the automatic lead seal installation mechanism of this utility model includes a three-axis moving mechanism 1 and a transfer mechanism 2. A main cylinder 3 is installed at the output end of the three-axis moving mechanism 1. An auxiliary cylinder 4 is connected to the output end of the main cylinder 3. An installation frame 5 is connected to the output end of the auxiliary cylinder 4. A suction nozzle 6 is installed on the installation frame 5. An air pump is connected to the power end of the suction nozzle 6.

[0027] The transfer mechanism 2 includes a bracket 21, on which a transfer box 22 is mounted. The transfer box 22 has several inlet ports 23 on its side, which are arranged horizontally. A transfer block 24 is slidably installed inside the transfer box 22. The transfer block 24 has placement slots 25 corresponding to the number of inlet ports 23, and the placement slots 25 are positioned to match the inlet ports 23. The transfer block 24 is connected to a stop block 26 whose size and specifications match the inlet ports 23. A cylinder 27 is mounted on the transfer box 22, and the output end of the cylinder 27 is connected to the transfer block 24. A cover plate 28 is mounted on the transfer box 22, and a laser sensor 29 corresponding to the number of inlet ports 23 is mounted on the cover plate 28. The cover plate 28 has a material removal port 210 corresponding to the number of inlet ports 23. Both the transfer box 22 and the placement slots 25 have a conduction port 211 whose position corresponds to the laser sensor 29.

[0028] In this implementation, the automatic feeding mechanism for lead seals, such as the output end of a vibratory feeder, is connected to the inlet 23. The multiple inlets 23 allow for the installation of multiple feeding mechanisms, and can accommodate lead seals of different sizes depending on the specifications of the inlets. After the lead seal enters the inlet and into the placement slot 25, it blocks the on / off state of the laser sensor 29 in the transmission port 211, thus giving the laser sensor 29 a signal that the lead seal is in place. The cylinder 27 starts operating, pushing the transfer block 24 to move within the transfer box 22, causing the corresponding number of lead seals in the placement slots 25 to move together. During this movement, the stop block 26 and the two adjacent placement slots 25... The side wall of the transfer block 24 blocks the inlet 23 to prevent the subsequent lead seals from entering, achieving the effect of sequential transfer. The transfer block 24 moves to the set position and stops under the stroke control of the cylinder. When the lead seal is moved directly below the feeding port 210, the three-axis moving mechanism 1 drives the suction nozzle 6 to move directly above the feeding port 210. The main cylinder 3 runs quickly first, driving the auxiliary cylinder 4 to move quickly a distance. Then the auxiliary cylinder 4 runs slowly, so that the suction nozzle 6 contacts the upper surface of the lead seal. This two-end operation mode increases the running speed. The air pump runs and takes the lead seal out of the transfer box 22 through the suction nozzle 6. Then the three-axis moving mechanism 1 transfers and installs it in the required position.

[0029] The cylinder 27 operates, driving the transfer block 24 back to its original position, and proceeding to transfer the lead seals of the next group one by one.

[0030] Example 2:

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the bracket 21 is provided with a waist-shaped hole 212. The transfer box 22 is installed on the bracket 21 through the waist-shaped hole 212. This design allows for a certain degree of fine adjustment of the installation height of the transfer box 22, thereby adapting to the feeding mechanism of different height output ends, such as the feeding docking of the vibratory feeder.

[0032] In this embodiment, the oblong hole 212 has an adjustment and clearance effect, which allows the installation position of the transfer box 22 to be adjusted. In fact, the installation height of the transfer box 22 can also be adjusted by setting multiple sets of mounting holes in the longitudinal direction. The mounting holes have higher installation reliability than the oblong hole, but the adjustment accuracy is relatively lower.

[0033] Example 3:

[0034] like Figure 3 As shown, two top posts 213 are installed between the transfer block 24 and the transfer box 22. The two top posts 213 are located next to the stop block 26. With this design, when the cylinder 27 has an abnormality or other problem that causes overtravel, the stop block 26 will not collide with the transfer box 22, thus ensuring that the stop block 26 will not be damaged due to collision.

[0035] In this implementation, the top column 213 mainly serves as a counterweight, and its number and shape are not limited. In fact, the collision between the stop block 26 and the inner wall of the transfer box 22 can also be prevented by limiting the stroke on the output shaft of the cylinder 27.

[0036] Example 4:

[0037] like Figure 3 As shown, the transfer block 24 is provided with a mating groove 214, and the transfer box 22 is equipped with an adjusting screw 215. The end of the adjusting screw 215 is equipped with an abutment 216, and the position of the abutment 216 corresponds to the mating groove 214. This design prevents overtravel while accurately adjusting the moving position of the transfer block 24 so that the position of its placement groove 25 is directly opposite the material pick-up port 210.

[0038] In this embodiment, the engagement of the contact head 216 and the mating slot 214 also controls the stroke of the transfer block 24. Therefore, the stroke can also be controlled on the cylinder 27 according to the actual situation.

[0039] Example 5:

[0040] like Figure 3 , Figure 4 As shown, some feed inlets 23 are provided with first positioning ribs 217, and corresponding slots 25 for the placement of the first positioning ribs 217 are provided with second positioning ribs 218. This design is suitable for the transfer of some lead seals that require positioning, and the first positioning ribs 217 and the second positioning ribs 218 achieve the positioning effect.

[0041] In this embodiment, the specifications and dimensions of the first positioning rib 217 and the second positioning rib 218 are adapted to the opening size of the lead seal, thereby ensuring that the axial angle of the lead seal will not change when the transfer block 24 moves the lead seal. Then, when it is subsequently picked up and transferred by the suction nozzle 6 for installation, the angle can be adapted for installation, ensuring the normal installation.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
