Description

Technical Field

[0001] This utility model relates to array-type devices, and more particularly to an array-type e-cigarette cartridge filling device. Background Technology

[0002] E-liquid-based electronic cigarette cartridges contain an e-liquid reservoir. In cartridge production, the e-liquid filling process typically employs an array-type filling method, utilizing upper and lower molds for filling. The upper mold is designed as an array of injection syringes, with injection needles at the bottom. Each injection syringe is connected to an injection pump. The lower mold is designed as an array of cartridges, with each array of syringes corresponding to the array of cartridges in the lower mold. Before filling, the upper mold approaches the lower mold, inserting the injection needles into the cartridge. The injection pump then pumps the e-liquid into the cartridge. A one-way valve inside the injection pump controls the pumping rate, adjusting the e-liquid level in each cartridge.

[0003] For example, Chinese utility model patent CN 204643794U discloses an e-cigarette atomizer filling device, which fills e-cigarettes with e-cigarettes by using an e-cigarette pump equipped with a one-way valve. This method of controlling the e-cigarette volume with an e-cigarette pump using a mechanical one-way valve has defects. Since the e-cigarette cartridges are generally small in size, multiple e-cigarette pumps are required in production scenarios that handle multiple e-cigarette targets. Furthermore, because the e-cigarette pump is relatively complex in design and large in size, it is difficult to fill e-cigarettes in large quantities, is prone to mechanical structure failures, and is difficult to manufacture and maintain.

[0004] In addition, if a manufacturer of e-liquid needs to change the type of e-liquid during the production process, it needs to replace the entire e-liquid filling mechanism. Otherwise, due to the complex structure of the e-liquid filling device, it will face the defect of being difficult to clean.

[0005] Therefore, there is an urgent need in this field for a cigarette cartridge filling device that can further improve production efficiency and has a simpler structure. Utility Model Content

[0006] The purpose of this invention is to provide an oil filling device that can achieve large-scale oil filling of e-cigarette cartridges, higher production efficiency, and simpler structure, thereby overcoming the shortcomings of existing technologies that can only complete the oil filling process of a small number of e-cigarette cartridges in one oil filling operation.

[0007] Based on this, the present invention provides an array-type e-cigarette cartridge filling device, the device including a drive mechanism, a piston array mechanism, an filling array mechanism, an e-cigarette cartridge array fixture and a positioning mechanism, characterized in that the piston array mechanism includes a piston array composed of multiple piston rods 9 assembled together;

[0008] The oil injection array mechanism has an oil injection needle array composed of multiple oil injection needles 15 and an extension frame 24 that protrudes upward around the oil injection needle array. An inner recess 25 is formed in the extension frame 24. An oil inlet 21 is provided on the outer wall of the extension frame 24 and an oil inlet groove 22 is provided on the inner wall of the extension frame 24. The oil inlet 21 communicates with the oil inlet groove 22. The oil injection needle 15 includes an oil injection needle tube 152 with an inner diameter matching the piston rod 9 and an oil injection needle head 151 located at the lower end of the oil injection needle tube 152.

[0009] The positioning mechanism includes a base 17 for fixing the cigarette cartridge array fixture 16, and matching guide shafts 7 and bushings 6 respectively mounted on the drive mechanism, piston array mechanism, oil injection array mechanism and / or base 17.

[0010] The drive mechanism drives the piston array mechanism to reciprocate up and down.

[0011] In this invention, the driving mechanism includes a servo motor 1, which drives the piston array mechanism to perform up-and-down reciprocating motion.

[0012] Furthermore, the drive mechanism also includes a fixed plate 2 that is fixedly connected to the output end of the servo motor 1. The fixed plate 2 is connected to the movable plate 5 via a movable joint 3 and a flange 4 fixed on the movable plate 5. The servo motor 1 drives the movable plate 5 to perform up-and-down reciprocating motion.

[0013] Preferably, the piston array mechanism further includes a piston array mounting plate 8, through which the piston array is fixedly assembled together, and the piston rods 9 in the piston array are arranged vertically downwards.

[0014] More preferably, the top of the piston rod 9 is tapped and connected to the lower surface of the piston array mounting plate 8 via a threaded connection.

[0015] In this invention, a sealing silicone ring 18 is provided at the lower end of the piston rod 9, and the outer diameter of the sealing silicone ring 18 matches the inner diameter of the oil injection needle tube 152.

[0016] As another preferred embodiment, a liquid level detection hole 23 communicating with the inner wall of the extension frame 24 is provided on the extension frame 24.

[0017] In this invention, the oil injection array mechanism can be an integral structure or a modular structure assembled from multiple parts.

[0018] Preferably, the bottom of the oil injection needle tube 152 is tapped, and the oil injection needle tube 152 and the oil injection needle head 151 are connected together by tapping the top of the oil injection needle head 151.

[0019] In this invention, the number of individuals within the piston array mechanism, the oil injection array mechanism, and the cigarette cartridge array fixture is the same.

[0020] This invention enables synchronous array-style oil injection in a face-to-face manner, greatly improving oil injection efficiency. The oil injection mechanism of this invention uses a servo mechanism to precisely control the oil injection action. Its unique structural design allows for precise quantitative control of the oil, and its simple structure makes device maintenance easier and more convenient. Attached Figure Description

[0032] The following embodiments are used to explain the technical solution of this utility model in a non-limiting manner.

[0033] Example 1

[0034] like Figure 1 The array-type e-cigarette cartridge filling device shown includes a drive mechanism, a piston array mechanism, an filling array mechanism, an e-cigarette cartridge array fixture, and a positioning mechanism.

[0035] The drive mechanism is used to drive the piston array mechanism to perform up-and-down reciprocating motion. It includes a servo motor 1 with a vertically downward output direction and a fixed plate 2 fixedly connected to the output end of the servo motor 1. The fixed plate 2 is connected to the movable plate 5 via a movable joint 3 and a flange 4 fixed on the movable plate 5. The servo motor 1 drives the movable plate 5 to perform up-and-down reciprocating motion. The output of the servo motor 1 ultimately drives the movable plate 5 to perform up-and-down reciprocating motion.

[0036] The piston array mechanism includes a piston array composed of multiple piston rods 9 and a piston array mounting plate 8. The piston array is fixedly mounted on its lower surface by the piston array mounting plate 8. Each piston rod 9 is oriented vertically downwards, thus it can reciprocate up and down under the drive of a servo motor. In addition, a sealing silicone ring 18 is provided at the lower end of the piston rod 9. When the sealing silicone ring 18 cooperates with the oil injection needle tube 152, it can achieve a seal between the piston rod and the oil injection needle.

[0037] In this embodiment, for ease of manufacturing, the oil injection array mechanism is assembled from separate components, such as... Figure 4-8 As shown. The oil injection array structure can be maintained at a stable height through the reserved fixing holes or positioning devices (or movable fixing mechanisms) to ensure that the oil injection array can be accurately positioned at a certain distance above the cartridge array fixture. The oil injection array mechanism includes an oil injection needle array 26 with multiple oil injection needles 15 and an extension frame 24 for mounting the oil injection needle array. After the oil injection needle array 26 is installed with the extension frame 24, a concave area 25 is formed in the extension frame 24. An oil inlet 21 is provided on the outer wall of the extension frame 24, and an oil inlet groove 22 is provided on the inner wall of the extension frame 24. The oil inlet 21 communicates with the oil inlet groove 22. Multiple oil injection needle tubes 152 with inner diameters matching the piston rod 9 are constructed in the oil injection needle array 26, and the bottom of the oil injection needle tubes 152 are tapped for connection with the oil injection needle head 151, thereby forming the oil injection needles 15. A liquid level detection hole 23 is also provided on the inner wall of the extension frame 24.

[0038] The base 17, drive mechanism, piston array mechanism, and e-liquid injection array mechanism, which include a fixed cartridge array fixture 16, are connected by a positioning mechanism. The positioning mechanism includes a pair of guide shafts 7 and bushings 6 that are set and fixed on the drive mechanism, piston array mechanism, and e-liquid injection array mechanism, ensuring that the piston rod can reciprocate above the e-liquid injection needle under the drive of the servo motor, squeezing the e-liquid in the e-liquid injection needle into the cartridge located in the cartridge array fixture 16.

[0039] During operation, as the array oil tank fixture 16 is transferred to the fixture positioning plate 17 placed on the lower part of the machine body, the external oil pump pumps e-liquid into the common oil tank 12 until the liquid level detector level is reached, at which point the pumping stops. The servo drive unit 1 then moves the central movable plate 5 downwards along the guide optical axis 7 until the piston is initially inserted into the oil filling tank to form a seal. The oil that is initially pressed down is collected and recovered by the oil filling pool. After the array oil tank fixture 16 is installed on the fixture positioning plate 17, it moves along the guide rail to the oil filling area inside the machine. At this time, the array oil tank fixture 16 is filled with 1600 e-liquid cartridges to be filled, which are aligned one-to-one with the oil filling needles 15 of the oil filling mechanism. The number of oil filling needles is also the same. For 1600 units, the upper servo mechanism lowers the entire oil filling mechanism, causing the oil filling needle array 15 to insert into the cartridge. The servo drive part 5 of the middle oil filling mechanism causes the middle movable plate 5 to continue moving downwards for a distance to complete the oil filling. The upper servo mechanism then raises the entire oil filling mechanism, causing the oil filling needle array 15 to leave the cartridge. Subsequently, the array oil tank fixture 16 and fixture positioning plate 17 move away from the oil filling position along the guide rail and a new array oil tank fixture 16 is replaced. During the replacement process, the servo drive part 5 of the oil filling mechanism moves the middle movable plate 5 upwards until the piston array leaves the oil tank. The external oil pump (not shown in the attached figure) then starts pumping oil again to prepare for the next oil filling.

[0040] This invention enables synchronous array-style oil injection in a face-to-face manner, greatly improving oil injection efficiency. Precise control of the oil injection action is achieved through a servo mechanism, and the unique structural design enables precise quantitative control of the oil. The simple structure makes the device easier and more convenient to maintain.
