Description

Technical Field

[0001] This utility model relates to the field of dispensing and potting technology, and more specifically, to a quick-release dispensing syringe device. Background Technology

[0002] Currently, in the 3C dispensing industry, adhesive flows out through a feeder. To ensure dispensing effectiveness and obtain qualified products, a bubble detection module is generally required. The dispensed adhesive cannot be used until all bubbles are removed and must be discharged into a waste liquid collection module. This module uses a glue cartridge connected to a tabletop machine via a dispensing conduit to collect waste adhesive. With increasingly stringent requirements for machine appearance and size, the waste liquid collection module needs to be installed within confined spaces. Therefore, convenient waste adhesive collection and quick disassembly and cleaning of the glue cartridge are crucial issues that need to be addressed. Utility Model Content

[0003] The problem solved by this utility model is how to provide an integrated design and a quick-release glue dispensing syringe device that can be easily disassembled.

[0004] To address the aforementioned problems, this utility model provides a quick-release glue-discharging syringe device, comprising: a syringe, a cap, and a mounting base. The syringe is placed on the mounting base, and the cap is positioned at the opening of the syringe. The cap includes a cap body, a lock nut connector, a return spring, a wedge-shaped buckle, a guide limiting piece, and a PC connector. The cap body has a glue channel, and the lock nut connector and the PC connector are respectively fixed to the outer and inner sides of the glue channel. The opening of the syringe has an edge flange that matches the cap body. The symmetrical sides of the cap body extend to form mounting grooves. The wedge-shaped buckle is positioned within the mounting groove, and its end is fixed to the outer wall of the cap body by a return spring. When the cap body covers the opening of the syringe, the wedge-shaped buckle, under the action of the return spring, engages the edge flange of the syringe for fixation. The guide limiting piece is fixed at the bottom opening of the mounting groove.

[0005] Furthermore, the top surface of the cylinder cover body is provided with a first horizontal slide rail opening corresponding to the mounting groove. The top of the wedge buckle is provided with a toggle component. The toggle component extends out of the cylinder cover body from the first slide rail opening and can slide along the first slide rail opening. By toggling the toggle component along the first slide rail, the wedge buckle compresses the return spring, thereby opening the cover.

[0006] Furthermore, the bottom front end of the wedge buckle is a slope. When the syringe is installed upwards, the upward force of the syringe is decomposed into a horizontal direction under the action of the slope, which cancels out the horizontal friction force and the reset force of the reset spring, so that the slope of the wedge buckle moves along the edge flange of the syringe, and the wedge buckle compresses the spring and is installed in place.

[0007] Furthermore, the mounting base includes a mounting plate and a mounting block. The mounting plate includes a base plate, a connecting plate, a sensor placement plate, and a fixing plate. The connecting plate is perpendicularly connected to the side of the base plate. The mounting block is fixed to the connecting plate. The mounting block has a central fitting hole with a diameter matching that of the syringe, so that the syringe can pass through the fitting hole and place its bottom on the base plate. The sensor placement plate is perpendicularly connected to the upper side of the connecting plate. The fixing plate is perpendicularly connected to the sensor placement plate for fixing the mounting base.

[0008] Furthermore, the bottom of the syringe is provided with a hexagonal boss, and the base plate is provided with a hexagonal through hole corresponding to the boss, so as to restrict the rotation of the syringe.

[0009] Furthermore, the mounting block has first threaded holes on both sides of the side where it connects with the connecting plate. The connecting plate has vertical openings at positions corresponding to the first threaded holes, forming first mounting rails. Matching bolts pass through the first mounting rails and the mounting block is fixed to the connecting plate through the first threaded holes. The position of the mounting block can be adjusted by installing it at different positions on the first mounting rails.

[0010] Furthermore, the syringe device also includes a liquid level detection device, which includes a mounting sheet metal and a liquid level sensor fixed on the mounting sheet metal. The mounting sheet metal is L-shaped, and the sensor placement plate is provided with a second threaded hole. The bottom surface of the mounting sheet metal is provided with a second mounting rail corresponding to the second threaded hole. There are two liquid level sensors, which are arranged side by side on the side of the mounting sheet metal.

[0011] Furthermore, the syringe device also includes a glue receiving tray, which is placed below the syringe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The mounting base allows for quick and easy installation and fixation of the syringe. The syringe features an integrated design, with the cap utilizing a clever wedge-shaped buckle and a return spring structure, achieving both seamless integration and quick disassembly. Furthermore, the dual liquid level sensor design facilitates smoother machine operations. Attached Figure Description

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0018] like Figure 1As shown, this utility model provides a quick-release glue dispensing syringe 2 device, including syringe 2, syringe cap 1, mounting base 4, liquid level detection device 3, and glue receiving tray 5.

[0019] like Figure 2 As shown, the cap 1 is the core component in this embodiment, consisting of a cap body 1.1, a lock nut connector 1.2, a return spring 1.3, a wedge buckle 1.4, a guide limiting piece 1.5, and a PC connector 1.6. Its innovative design greatly facilitates the installation and disassembly of the syringe 2. The solution is as follows: The dual-path glue discharge system is equipped with two lock nut connectors 1.2, which connect to the glue discharge system and are then fixed by the cap body 1. Furthermore, the glue path extending into the syringe 2 is equipped with a PC connector, allowing for quick insertion and removal of the catheter. This configuration has a clear purpose: the lock nut connector 1.2 at the glue inlet securely fixes the glue discharge system to the cap 1, preventing any misoperation from pulling it out, thus improving the safety and stability of the equipment. The internal PC connector 1.6 facilitates disassembly, cleaning, and replacement of catheter consumables, reducing manual maintenance time and manpower waste. Meanwhile, the cap 1 is also equipped with a vent port, which facilitates balancing the pressure difference between the air pressure inside the syringe 2 and atmospheric pressure, making it easier for the equipment to discharge glue. Another key feature of the cap 1 is its quick installation and removal function. (Reference) Figure 3 The opening of the syringe 2 is provided with an edge flange 2.1 that matches the main body 1.1 of the cap. Utilizing the original edge flange 2.1 at the top of the syringe 2, the syringe 2 can be tightly fastened to the cap 1 under the action of the wedge buckle 1.4. The principle is that the front end of the wedge buckle 1.4 is designed with a two-sided wedge structure. After the syringe 2 is in place, the wedge buckle 1.4, under the action of the return spring 1.3, firmly fastens the syringe 2. The small angle of the inclined surface at the top of the wedge buckle 1.4 provides a strong upward force. When the syringe 2 needs to be removed, without manual activation of the wedge buckle 1.4, the downward pressure generated by the syringe 2 on the small inclined surface is decomposed to the horizontal and cannot offset the horizontal frictional force, thus improving the installation safety. When the syringe 2 needs to be removed, the operator only needs to push the wedge buckle 1.4 through the part of the wedge buckle 1.4 that extends out of the cap 1, and the wedge buckle 1.4 will compress the spring and move outward, disengaging the top from the edge flange 2.1, so that the syringe 2 can be removed. Meanwhile, the wedge buckle 1.4 has a large slope at its bottom, so when installing the syringe 2, there is no need to manually engage the wedge buckle 1.4. When the syringe 2 is installed upwards, the upward force of the syringe 2 is decomposed into a horizontal direction under the action of the slope, which can easily offset the horizontal friction force and the return spring force of the return spring 1.3, ensuring proper installation. The guide limit plate 1.5 is designed according to the shape of the cap 1, which facilitates installation while making the cap 1 compact and integrated, effectively controlling its size and weight.

[0020] like Figure 4As shown, the mounting base 4 consists of a mounting plate 4.1 and a mounting block 4.2. When installing the syringe 2, it can be mounted onto the fixed mounting base 4 simply by moving it from top to bottom. The fixing method uses gravity and interference fit. The mounting plate 4.1 provides upward support for the syringe 2, restricting movement in one direction. Simultaneously, its hexagonal through-hole at the bottom matches the hexagonal protrusion at the bottom of the syringe 2, also restricting rotation in one direction. The mounting block 4.2, with a circular hole similar in diameter to the syringe 2, allows the syringe 2 to fit snugly inside. Combined with the hexagonal through-hole at the bottom of the mounting plate 4.1, it restricts movement and rotation in two directions for the syringe 2. Thus, through interference friction and gravity, the six degrees of freedom of the syringe 2 are restricted and completely fixed.

[0021] like Figure 5 As shown, for syringes 2 with slightly different sizes, the mounting base 4 also has an adjustable method to completely fix the syringe 2. The mounting block 4.2 has first threaded holes on both sides of the side where it connects with the mounting plate 4.1. The connecting plate of the mounting plate 4.1 has vertical openings to form first mounting rails. The mounting block 4.2 can be adjusted in position along the vertical openings, so that the mounting block 4.2 can be adjusted up and down by height A on the mounting plate 4.1 to accommodate syringes 2 of different heights. At the same time, it determines how far the syringe 2 needs to be moved upward to be completely removed, adapting to machines with different space requirements. For syringes 2 with slightly different diameters, there are corresponding adjustment methods. Since the opening width is slightly larger than the first threaded hole, the matching bolt passes through the opening and enters the first threaded hole for fixing. When fixing, the mounting block 4.2 can have a slight tilt angle. By adjusting the tilt angle B of the mounting block 4.2 on the mounting plate 4.1, and by designing the mounting block 4.2 to have a certain thickness, the tilt can reduce the minimum diameter of the mounting block 4.2 in the vertical direction, which can more firmly fix the syringe 2 on the mounting base 4 without changing the size of the through hole diameter of the mounting block 4.2.

[0022] like Figure 6As shown, the liquid level detection device 3 consists of a mounting sheet metal 3.1 for the liquid level sensor and a liquid level sensor 3.2. The ingenious dual-liquid-level sensor design can meet the needs of most customers. When the glue level during dispensing is nearly full, the lower liquid level sensor 3.2.1 senses the glue and sends a signal, reminding the user that the dispensing is about to be full and prompting them to take action. When the upper liquid level sensor 3.2.2 senses the glue and sends a signal, it will display that the dispensing is full and action must be taken before dispensing can continue; otherwise, it will cease normal operation. This design provides a warning time, rather than the device ceasing operation immediately upon indicating that the glue is full, which significantly impacts production efficiency. The mounting sheet metal 3.1 for the liquid level sensor is designed with an adjustable front and rear structure to accommodate different types of glue, allowing for better glue detection through adjustment.

[0023] At the same time, such as Figure 1 As shown, a glue receiving tray 5 is also added. The design of the glue receiving tray 5 is a redundant design, which is used to prevent glue from leaking from the glue bucket into the machine and affecting the normal operation of the machine, thereby improving the safety of the equipment.

[0024] The overall operating principle of this utility model is as follows: First, the cap 1 is connected to the glue discharge tube inside the machine. Since there are no parts that need to be disassembled, there is no risk of losing parts during operation. During the installation of the syringe 2, the syringe 2 is first installed on the mounting base 4, and then the cap 1 is inserted. During the disassembly of the syringe 2, there are two methods: First, the cap 1 can be removed by manually pressing the wedge buckle 1.4, and then the syringe 2 filled with glue can be removed; second, the cap 1 and syringe 2 can be removed as a whole, and then the cap 1 can be removed from the syringe 2.

[0025] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
