[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0032] Automatic dispensing equipment is suitable for supporting the dispensing needs of automated production lines in high-tech industries. In the manufacturing of automotive components, such as head-up displays and electronic rearview mirrors, dispensing is often required. Existing automatic dispensing equipment requires a fixing mechanism to secure the syringe, which is then driven by a robotic arm, cylinder, or other actuation method to move the syringe. However, the applicant found that RTV adhesive needs to be poured from a large glue container into the dispensing syringe before automatic dispensing. Due to the large amount of adhesive dispensed, operators need to frequently change and add adhesive. Therefore, addressing the issue of reduced production efficiency caused by frequent operations is an area that needs improvement.

[0033] Please see Figure 1 and 2 This utility model provides an adhesive fixing mechanism for use in automatic dispensing equipment, including: a moving module 100;

[0034] A fixed frame 200 is provided on the movable module 100, and the fixed frame 200 is provided with an upper through hole 201 and a lower through hole 202;

[0035] The rubber tube 300 is placed inside the upper through hole 201;

[0036] The needle 400 passes through the lower through hole 202 and connects to the glue outlet of the glue cartridge 300; and,

[0037] Fastener 500 extends into the upper through hole 201 and contacts and positions itself with the rubber sleeve 300.

[0038] This invention facilitates the replacement of rubber cartridges by setting fasteners, reducing the difficulty of replacement, improving replacement efficiency, and thus increasing production efficiency.

[0039] In one embodiment, the mobile module 100 described in this application is driven to move by a drive component, which may be a cylinder drive component, an electric drive component, etc., which are existing technologies and will not be described in detail here.

[0040] In one embodiment, because the amount of glue dispensed is relatively large, the operator needs to frequently change and add glue. The glue dispensing syringe can only hold 30-40 ml of glue at a time, and there will be some glue loss after each dispensing. This application replaces the glue syringe 300 with the existing 50 ml glue syringe to a 330 ml glue syringe, eliminating the need for dispensing glue, reducing glue changing time, increasing product production volume, and improving production efficiency.

[0041] In one embodiment, please refer to Figure 3 The fastener 500 includes a fastening bolt that extends into the inner wall of the upper through hole 201. In this embodiment, the positioning can be achieved by tightening the fastening bolt against the rubber sleeve 300, which is simple to operate, low in cost, and has a good positioning effect.

[0042] Preferably, a buffer block can be provided at the end of the fastening bolt to protect the rubber sleeve 300.

[0043] In one embodiment, another implementation of the fastener 500 is provided; please refer to [link to relevant documentation]. Figure 4 The fastener 500 may also include two arc-shaped clamping blocks that are movably embedded in the inner wall of the upper through hole 201 and are distributed opposite each other. The two arc-shaped clamping blocks position the rubber sleeve 300 by moving away from or close to each other.

[0044] Specifically, the arc-shaped clamping block can be moved by an external pull rod, and the arc-shaped clamping block maintains the clamping force on the rubber cylinder 300 through an elastic element.

[0045] In one embodiment, please refer to Figure 1 and Figure 5 It also includes a needle holder 600, which has a through needle hole 601, through which the needle 400 is installed.

[0046] In this embodiment, the length of the syringe 400 should be between 15 and 20 cm to achieve dispensing accuracy. If it is too short, the product interference distance will be too far from the dispensing position, and the dispensing position accuracy will not be achieved. If it is too long, the swing of the glue cartridge 300 will also affect the dispensing position accuracy. The stability of the syringe 400 and the dispensing accuracy are improved by setting the syringe holder 600.

[0047] In one embodiment, please refer to Figure 6 The upper opening of the needle tube hole 601 is tapered. This design in this embodiment facilitates the guidance of the needle tube 400 through the tapered hole when installing the tubing 300, making it easier for the needle tube 400 to enter the needle tube holder 600.

[0048] In one embodiment, a protective layer is attached to the inner wall of the needle hole 601. This arrangement in this embodiment facilitates the protection of the needle 400, reducing damage caused by the collision between the needle tip and the inner wall of the needle hole 601 during installation, and also protecting the needle 400 during dispensing.

[0049] Specifically, the protective layer can be made of rubber.

[0050] In one embodiment, please refer to Figure 6 The lower opening of the needle tube hole 601 is provided with a tapered sleeve 602. The tapered sleeve 602 is provided with a through hole 603 for the needle tube 400 to pass through. A glue removal ring 604 is provided at the through hole 603. The inner diameter of the glue removal ring 604 is adapted to the needle tube 400, and the surface of the glue removal ring 604 is a tapered surface.

[0051] In this embodiment, the adhesive removal ring 604 is designed to remove any adhesive residue accidentally left on the syringe 400, preventing the adhesive from being carried into the syringe holder 600 or the fixing frame 200 and affecting the subsequent replacement of the glue cartridge 300.

[0052] In one embodiment, the conical sleeve 602 is detachably connected to the syringe holder 600. This configuration facilitates the removal of the conical sleeve 602 along with the adhesive removal ring 604 for cleaning or replacement, thereby achieving a better adhesive removal effect.

[0053] In one embodiment, please refer to Figure 6 A magnetic snap fastener 605 is embedded in the conical sleeve 602, and the magnetic snap fastener 605 is attracted and fixed to the needle holder 600. In this embodiment, the magnetic snap fastener 605 makes it easy for staff to replace the conical sleeve 602, and the operation is simple, quick and saves time.

[0054] In one embodiment, an anti-abrasion pad is provided on the outer surface of the glue cartridge 300. In this embodiment, the anti-abrasion pad is made of an opaque material, which can prevent the glue inside the glue cartridge 300 from deteriorating when exposed to light.

[0055] It should be noted that if the embodiments of this utility model involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.

[0056] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent.

[0057] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
