Description

Technical Field

[0001] This utility model relates to the field of glue dispensing machine technology, specifically to a swing-type glue dispensing mechanism. Background Technology

[0002] An AB dispensing machine is a specialized device for the automated proportioning, mixing, and dispensing of two-component adhesives. Its core component, the dispensing head, typically consists of a feeding valve, a precision metering unit, and a mixing mechanism. The mixing mechanism primarily employs two technical approaches: one utilizes a static mixing tube with a specific blade structure, relying on the fluid's own pressure to cut and overlap the adhesive solutions; the other uses a dynamic mixing valve with motor-driven spiral blades for forced mixing via mechanical means. During operation, the metering unit first precisely outputs the A and B components of the adhesive solution in a predetermined ratio. These components are then transported to the mixing mechanism for thorough fusion, and finally discharged continuously and uniformly through the outlet.

[0003] In existing technologies, common dispensing machines typically use a fixed-angle installation method for their dispensing heads, mostly set to perform dispensing operations perpendicular to the horizontal worktable. When the dispensing port of the workpiece is not vertically upward but has a certain tilt angle, in order to complete the dispensing task, the operator usually needs to adjust or reposition the workpiece to align the dispensing port of the workpiece with the outlet of the fixed-angle dispensing head, thereby adapting to different processing requirements.

[0004] However, the above-mentioned manual operation method requires repeated adjustment of the workpiece position to adapt to the glue injection angle, which is quite cumbersome. At the same time, the alignment accuracy of the manual operation method needs to be improved, and there may be occasional deviations between the glue injection port and the glue injection head, resulting in waste of glue. Utility Model Content

[0005] The purpose of this invention is to provide a swing-type glue dispensing mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a swing-type glue injection mechanism, comprising: a frame, a gear plate rotatably mounted on the top of the frame, a glue injection head fixedly mounted on one side of the gear plate, and a first drive component for driving the gear plate to rotate connected to the lower side of the gear plate; Stabilizing mechanisms are provided on both sides of the gear plate edge. The stabilizing mechanism includes a set of relatively movable clamping plates. One end of the clamping plate is fixedly connected to an anti-slip rubber block, and the other end of the clamping plate is connected to a second drive assembly for driving the relative movement of the clamping plates. Preferably, the first drive component includes a motor, which is fixedly mounted on the frame. The output end of the motor passes through the frame and is fixedly connected to a gear. The upper side of the gear meshes with a gear plate for transmission.

[0007] Preferably, the gear disc shaft is fixedly connected to one end of the limiting shaft, and the other end of the limiting shaft is rotatably sleeved in the frame.

[0008] Preferably, the gear disc has an annular groove on the side near the frame, the annular groove is slidably connected to one side of the ring rail, and the other side of the ring rail is fixedly connected to the frame.

[0009] Preferably, the second drive assembly includes a small cylinder, which is fixedly connected to one end of the support platform, and the other end of the support platform is fixedly connected to the top side wall of the frame.

[0010] Preferably, the output end of the small cylinder is fixedly connected to one side of the connecting block, and the other side of the connecting block is rotatably connected to one end of the two connecting plates via a large pin. The other ends of the two connecting plates are rotatably connected to the end of one of the clamping plates away from the anti-slip rubber block via small pins.

[0011] Preferably, the two clamping plates are rotatably connected to the support platform via a fixed shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the oscillating dispensing head design can automatically adjust the dispensing angle to adapt to the dispensing port of the workpiece with different inclination angles, effectively solving the problems of cumbersome operation and insufficient alignment accuracy caused by the reliance on manual repeated adjustment of the workpiece position in the prior art; at the same time, through the set clamping and stabilizing mechanism, the toothed disc displacement caused by factors such as pipeline tension and glue pressure fluctuation can be effectively suppressed during the dispensing process, thereby improving the stability and accuracy of the dispensing process and avoiding glue waste.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a swing-type glue injection mechanism, including: a frame 1, which serves as the main body of the entire device and provides stable support for the entire device; a gear disk 2 is rotatably mounted on the top of the frame 1, and the frame 1 restricts and supports the gear disk 2 to ensure its rotational stability; a glue injection head 3 is fixedly mounted on one side of the gear disk 2, which is prior art and will not be described in detail here; a first drive component for driving the gear disk 2 to rotate is connected to the lower side of the gear disk 2; stabilizing mechanisms are set on both sides of the edge of the gear disk 2 to stabilize the gear disk 2 and prevent displacement of the gear disk 2 during glue injection, thereby affecting the glue injection stability; the stabilizing mechanism includes a set of relatively movable clamping plates 4, one end of which is fixedly connected to an anti-slip rubber block 5, which increases the friction between the clamping plate 4 and the gear disk 2 and further improves the clamping stability of the clamping plate 4 on the gear disk 2; and the other end of the clamping plate 4 is connected to a second drive component for driving the clamping plate 4 to move relatively.

[0017] When in use, if the workpiece is placed at the bottom of the frame 1 and its glue inlet is not perpendicular to the horizontal plane but is skewed, the first drive component drives the gear plate 2 to rotate under the limit of the frame 1. This causes the gear plate 2 to drive the glue inlet head 3 to swing and adjust its angle, avoiding the trouble of manually adjusting the workpiece repeatedly and improving the efficiency of the entire glue inlet process. During this process, the anti-slip rubber blocks 5 on the clamping plate 4 are located on both sides of the edge of the gear plate 2. After the angle adjustment is completed, the second drive component drives the two clamping plates 4 to move towards each other, which in turn drives the anti-slip rubber blocks 5 to move closer to both sides of the gear plate 2 until they are in close contact with the surface of the gear plate 2. This further clamps and stabilizes the gear plate 2, thereby avoiding the influence of the binding force of the connecting pipeline, the impact and pressure fluctuation of the glue flow, and the mass and inertia of the glue inlet head 3 on the stability of the gear plate 2. Ultimately, this improves the accuracy and stability of the glue inlet head 3 during the glue inlet process.

[0018] Example 2: Based on Example 1, the first drive component includes a motor 6, which is electrically connected to an external control device. The motor 6 is fixedly mounted on the frame 1. The output end of the motor 6 passes through the frame 1 and is fixedly connected to a gear 7. The frame 1 provides limiting support for the output end of the motor 6. The upper side of the gear 7 meshes with the gear disc 2 for transmission. The shaft of the gear disc 2 is fixedly connected to one end of a limiting shaft 8. The other end of the limiting shaft 8 is rotatably sleeved inside the frame 1, limiting the gear disc 2. The gear disc 2 has an annular groove 9 on the side near the frame 1. The annular groove 9 is slidably connected to one side of a ring rail 10. The other side of the ring rail 10 is fixedly connected to the frame 1. Through the cooperation of the annular groove 9 and the ring rail 10, the rotational stability of the gear disc 2 is improved.

[0019] By controlling the motor 6 to start, it drives the gear 7 to rotate. Through the meshing transmission between the gear 7 and the gear disk 2, the gear disk 2 is driven to move. The gear disk 2 rotates under the limit of the limit shaft 8. At the same time, in order to improve the stability of the gear disk 2 during rotation, the sliding cooperation of the ring groove 9 and the ring rail 10 is used to further improve the stability of the gear disk 2 during rotation. Then, the rotation of the gear disk 2 drives the glue injection head 3 to swing, thereby realizing the convenient glue injection operation for workpieces with skewed glue injection ports.

[0020] Example 3: Based on Example 2, the second drive component includes a small cylinder 11, which is electrically connected to an external control device. The small cylinder 11 is fixedly connected to one end of a support platform 12, and the other end of the support platform 12 is fixedly connected to the top side wall of the frame 1. The frame 1 provides stable support for the support platform 12, and the support platform 12 provides stable support for the small cylinder 11. The output end of the small cylinder 11 is fixedly connected to one side of a connecting block 13. The other side of the connecting block 13 is rotatably connected to one end of two connecting plates 14 via a large pin. The other ends of the two connecting plates 14 are rotatably connected to the end of a clamping plate 4 away from the anti-slip rubber block 5 via small pins. The two clamping plates 4 are rotatably connected to the support platform 12 via a fixed shaft 15.

[0021] After the initial adjustment of the dispensing head 3 is completed, in order to ensure that the dispensing head 3 will not shake or deviate due to the restraining force of the connecting pipeline, the impact of the glue flow, and pressure fluctuations during the glue dispensing process, the output end of the small cylinder 11 is extended by controlling it to drive the connecting block 13 to move closer to the gear plate 2. Under the action of the moving connecting block 13, in conjunction with the rotation connection of the large pin shaft, one end of the connecting plate 14 is driven to rotate, and the other end of the connecting plate 14 pushes one end of the clamping plate 4 to move. The clamping plate 4 rotates under the limit of the fixed shaft 15, so that the ends of the two clamping plates 4 connected with the anti-slip rubber block 5 move towards each other until the anti-slip rubber block 5 is tightly attached to the edge of the gear plate 2, thereby limiting and fixing the gear plate 2, thus ensuring the stability of the dispensing head 3 during the glue dispensing process.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
