Automatic dispensing machines are widely used in industrial production, including integrated circuits, printed circuit boards, electronic components, automotive parts, handbags, and packaging boxes.

[0003] The nozzles of existing glue guns are generally detachable. However, since existing nozzles involve sealing, their structures are generally quite complex, making installation and disassembly rather troublesome. Utility Model Content

[0004] The main purpose of this utility model is to propose a glue gun with a detachable nozzle, which aims to improve the existing fitting structure between the nozzle and the main body, making it easy to disassemble and with good sealing performance.

[0005] To achieve the above objectives, this utility model proposes a glue gun with a detachable nozzle, comprising:

[0008] The manifold is provided with an insertion port at the lower end of the second output channel, and the insertion port is provided with an insertion tube;

[0009] The needle tip is provided with a mixing channel, and the lower end of the insertion tube extends into the mixing channel. The lower end of the mixing channel is a dispensing port.

[0010] A limiting ring sleeve is fitted onto the outer wall of the needle tip and fixed to the manifold or base.

[0011] Preferably, the delivery channel of the insertion tube is set at an angle or vertically.

[0012] Preferably, the second output channel is vertically arranged or has the same inclination direction as the first output channel;

[0013] Preferably, the needle tip and the insertion tube are integrally formed or installed separately.

[0014] Preferably, the lower part of the manifold is provided with a limiting part, and the upper wall of the needle tip is recessed with a groove that matches the limiting part.

[0015] The limiting part extends into the groove.

[0016] Preferably, the outer peripheral wall of the limiting part is provided with at least one notch, and the groove is provided with a locking part that cooperates with the notch.

[0017] Preferably, the outer peripheral wall of the needle tip is provided with a ridge, and the inner wall of the limiting ring is provided with a groove that matches the ridge.

[0018] Preferably, the limiting ring sleeve is detachably installed on the base or manifold via a screw or snap-fit ​​structure.

[0019] Preferably, the inner wall of the limiting ring is shaped to match the outer wall of the needle tip, thus achieving a contour-following locking structure.

[0047] like Figures 1 to 9 As shown, a glue gun with a detachable nozzle includes:

[0048] Base 1, the base 1 is provided with an inclined first output channel 10, the first output channel 10 is provided with at least two;

[0049] The glue injection device 2 (which can be a pneumatic glue gun or an electric glue gun) is located on the upper wall of the base 1. The glue injection device 2 is provided with a glue injection channel 20 that cooperates with the first output channel 10. The glue injection channel 20 is vertically arranged.

[0050] The manifold 3 is installed on the lower wall of the base 1, and the manifold 3 is provided with a second output channel 30 that communicates with the lower end of the first output channel 10.

[0051] The second output channel 30 is vertically arranged or has the same inclination direction as the first output channel 10;

[0052] The manifold 3 is provided with an insertion port 4 at the lower end of the second output channel 30, and the insertion port 4 is provided with an insertion tube 40;

[0053] The needle tip 5 is provided with a mixing channel 50, and the lower end of the insertion tube 40 extends into the mixing channel 50. The lower end of the mixing channel 50 is a dispensing port 51.

[0054] The limiting ring 6 is sleeved on the outer wall of the needle nozzle 5 and fixed to the manifold 3.

[0055] In the actual design, each structural module is designed, with the base 1 as the frame, and the upper wall is used to install the glue injection channel 20;

[0056] The lower wall is used to install the manifold 3 and the insertion tube 40, which can shorten the distance between the lower ends of the second output channels 30. Finally, the insertion tube 40 is installed.

[0057] Finally, at least two types of adhesive are mixed in the insertion tube 40 through the needle nozzle 5, thereby reducing the overall volume and height of the adhesive injection device 2.

[0058] Meanwhile, the small distance between the nozzle 5 and the dispensing port 51 effectively reduces problems such as clumping caused by the reaction after the glue is mixed, thus improving the stability of the glue dispensing process.

[0059] Its structure is simple and stable. Compared with the original German-imported Y-type bracket, the self-developed H-type bracket is more compact, easier to maintain, and reduces the total cost by 45%.

[0060] Specifically, the delivery channel of the insertion tube 40 is either inclined or vertical. In this application, a vertical arrangement is used, which reduces the problem of adhesive reaction between the ends and improves the smoothness of delivery.

[0061] In this embodiment of the invention, the outer peripheral wall of the glue dispensing device 2 is provided with a first monitoring hole 71 that extends into the first output channel 10.

[0062] The first monitoring port 71 is equipped with a first flow monitoring device 701. When the flow monitoring device is not needed, it can be sealed by a plug, thereby realizing flow monitoring.

[0063] Specifically, the outer peripheral wall of the manifold 3 is provided with a second monitoring hole 72 that extends into the second output channel 30.

[0064] The second monitoring port 72 is equipped with a second flow monitoring device 702. When the flow monitoring device is not needed, it can be sealed with a plug, further improving the accuracy of flow monitoring.

[0065] In this embodiment of the invention, the first flow monitoring device 701 and the second flow monitoring device 702 are pressure sensors. Other sensors can also be used. In addition to monitoring the presence or absence of adhesive, the sensors can also monitor the flow rate, thereby monitoring the adhesive supply status.

[0066] The pressure sensor detects whether there is any abnormality in the dispensing of glue from the glue dispensing device 2, such as insufficient glue, glue blockage, or glue ratio exceeding the range.

[0067] Specifically, the upper wall of the base 1 is recessed with a positioning hole, and the lower end of the glue injection device 2 extends into the positioning hole and is fixed by the first screw, thereby realizing a fully disassembled structure.

[0068] In this embodiment of the utility model, a positioning frame 8 is provided between multiple glue injection devices 2, and an auxiliary reinforcing locking block 80 fixed to the glue injection device 2 is provided on the upper part of the positioning frame 8; to prevent the glue gun from coming loose when it is mounted on the robot and moving at high speed.

[0069] The positioning frame 8 is provided with a limiting groove 81 that cooperates with the glue injection device 2. The limiting groove 81 ensures that the glue injection device 2 is parallel and perpendicular.

[0070] An adjustment seat 82 is provided between the rear wall of the positioning frame 8 and the rear wall of the base 1. The adjustment seat 82 has multiple adjustment holes along its height, and each adjustment hole is provided with a detachable positioning post 83.

[0071] The positioning post 83 is used for mounting on the robotic arm. It is equipped with four mounting positions to accommodate more installation heights and usage scenarios. With the quick-change mechanism of the positioning post 83, tool-free disassembly and installation can be achieved.

[0072] In this embodiment of the utility model, the needle tip 5 and the insertion tube 40 are integrally formed or separately installed.

[0073] This application adopts an integral molding structure, that is, the vertical insertion tube 40 and the mixing channel 50 are integrally molded, which improves the stability of the structure and makes installation simpler.

[0074] When the needle tip 5 and the insertion tube 40 are integrally formed, the upper wall of the needle tip 5 is provided with two protruding insertion tubes 40, and the insertion tubes 40 are inserted into the insertion port 4.

[0075] Specifically, the lower part of the manifold 3 is provided with a limiting part 91, and the upper wall of the needle tip 5 is recessed with a groove 92 that cooperates with the limiting part 91.

[0076] The limiting part 91 extends into the groove.

[0077] This achieves mutual positioning and flow channel sealing between the manifold 3 and the needle nozzle 5. The needle nozzle 5 is easy to install and lock, leaves no glue residue when replacing needles, and requires no cleaning or maintenance.

[0078] In this embodiment of the utility model, the outer peripheral wall of the limiting part is provided with at least one notch 101, and the groove is provided with a locking part 102 that cooperates with the notch 101, which further ensures the stability of positioning.

[0079] Equipped with a limiting ring sleeve 6, it can ensure that the position is consistent after the needle tip 5 is replaced. That is, the screw structure is used to achieve fixation, avoiding displacement caused by threaded fixation.

[0080] The outer peripheral wall of the needle tip 5 is provided with a ridge 200, and the inner wall of the limiting ring sleeve 6 is provided with a groove that matches the ridge 200.

[0081] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
