Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a dispensing mechanism in which the glue valve rotates around the dispensing point. Background Technology

[0002] With the rapid development of communication technology, 3C products, represented by mobile phones, computers, and wireless communication devices, have become the fastest-growing and most promising industry. Many 3C products involve dispensing processes during production. Dispensing, also known as gluing, coating, potting, or dripping, involves applying electronic adhesives, oils, or other liquids to a product through application, potting, or dripping, enabling the product to perform functions such as adhesion, encapsulation, insulation, fixation, and surface smoothing. Dispensing mechanisms are commonly used on dispensing machines or pick-and-place machines; they are automated mechanisms specifically designed to control fluids and dispense or coat them onto the surface or interior of a product, enabling path-based dispensing, precise positioning, and accurate glue control.

[0003] However, many 3C products, due to their varying internal structures, require careful dispensing to avoid interfering with the components during the gluing process. Furthermore, some 3C products require multi-point and multi-angle dispensing. Existing dispensing mechanisms can only perform dot, line, circular, or arc-shaped dispensing, and cannot handle multi-angle or multi-point dispensing. Currently, these multi-angle or multi-point dispensing operations are typically completed manually, resulting in low efficiency and high labor costs. Therefore, there is a need to design a dispensing mechanism suitable for 3C product production lines, capable of dispensing at different angles.

[0004] This invention provides a dispensing mechanism in which the glue valve rotates around a point, thereby solving the problem that existing dispensing mechanisms cannot perform multi-point, multi-angle dispensing operations. Utility Model Content

[0005] The purpose of this invention is to provide a dispensing mechanism in which the glue valve rotates around a point, so as to solve the problem that existing dispensing mechanisms cannot perform multi-point and multi-angle dispensing operations.

[0006] The technical solution of this utility model is: a dispensing mechanism with a glue valve rotating around a dot, including a substrate, a rotation drive module, an arc track assembly, and a glue valve disposed on the substrate;

[0007] The arc-shaped track assembly includes an arc-shaped track body and at least three pulleys fixedly mounted on the base plate;

[0008] The rotary drive module includes a drive component, a drive wheel, and a driven arc gear; the driven arc gear is fixed on the arc track body.

[0009] The glue valve is fixedly connected to the driven arc gear and is driven by the rotary drive module to rotate around the central axis of the arc track body.

[0010] Preferably, the rotary drive module further includes a connecting block; the drive member is disposed on one end face of the substrate, and the output end of the drive member passes through the substrate and is connected to the drive wheel; the driven arc gear is fixedly disposed on the arc track assembly, and the driven arc gear meshes with the drive wheel; the connecting block is fixedly disposed on the driven arc gear; and the glue valve is fixedly disposed on the connecting block.

[0011] Preferably, at least three pulleys are respectively disposed at the upper and lower ends of the arc-shaped track body; the pulleys abut against the upper and lower end faces of the arc-shaped track body; the driven arc-shaped gear is fixedly connected to the arc-shaped track body and drives the arc-shaped track body to move relative to the pulleys.

[0012] Preferably, the arc-shaped track assembly includes an arc-shaped track body and four pulleys; wherein two of the pulleys are spaced apart at the upper end of the arc-shaped track body, and the other two pulleys are spaced apart at the lower end of the arc-shaped track body.

[0014] Preferably, a limiting block is further provided between the glue valve and the connecting block; the limiting block is provided with an arc-shaped groove that matches the glue valve for accommodating the glue valve.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) The present invention provides a dispensing mechanism in which a glue valve rotates around a point. The dispensing mechanism can drive the arc-shaped track assembly and the glue valve to rotate through the rotation drive module, and limit the rotation path and rotation angle of the glue valve through the arc-shaped track assembly; thereby enabling the glue valve to complete continuous dispensing actions at different angles and multiple positions; making the dispensing mechanism applicable to dispensing operations in different occasions; not only helping to expand the application range of the dispensing mechanism, but also helping to realize the automatic dispensing process of different products on the same production line, improving the work efficiency of dispensing operations and reducing labor costs; and solving the problem that existing dispensing mechanisms in the prior art cannot perform multi-point and multi-angle dispensing operations.

[0017] (2) The present invention provides a dispensing mechanism for a glue valve to rotate around a point. The dispensing mechanism limits the rotation path and rotation angle of the glue valve by setting an arc track assembly, and achieves precise control of the rotation angle of the glue valve. At the same time, the arc track assembly can also improve the stability of the glue valve during the rotation process. Thus, the stability, flexibility and accuracy of the dispensing mechanism in the dispensing operation process are improved. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to specific embodiments:

[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the parts referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] A dispensing mechanism in which the glue valve rotates around a dispensing point, such as... Figure 1As shown, the system includes a substrate 1, a rotary drive module 2 and an arc-shaped track assembly 3 disposed on the substrate 1, and a glue valve 4. The arc-shaped track assembly 3 includes an arc-shaped track body 31 and at least three pulleys 32 fixedly disposed on the substrate 1. The rotary drive module 2 includes a drive member 21, a drive wheel 22, and a driven arc-shaped gear 23. The driven arc-shaped gear 23 is fixedly fixed on the arc-shaped track body 31. The glue valve 4 is fixedly connected to the driven arc-shaped gear 23 and is driven by the rotary drive module 2 to rotate around the central axis of the arc-shaped track body 31.

[0028] like Figure 2 As shown, the rotary drive module 2 also includes a connecting block 24. A drive member 21 is disposed on the rear end face of the substrate 1, and its output end extends through the substrate 1 to the front end face, where it is fixedly connected to the drive wheel 22 disposed on the front end face of the substrate 1. The drive member 21 drives the drive wheel 22 to rotate. A driven arc gear 23 is fixedly disposed on the arc track assembly 3, and meshes with the drive wheel 22, enabling the drive wheel 22 to drive the driven arc gear 23 to rotate, thereby driving the arc track assembly 3 to rotate. The connecting block 24 is fixedly disposed on the driven arc gear 23. The glue valve 4 is fixedly disposed on the connecting block 24 and rotates with the driven arc gear 23, thereby completing multi-angle and continuous dispensing actions. This allows the dispensing mechanism to be applicable to dispensing operations in more situations. In this embodiment or other embodiments, the drive member 21 can be a servo motor, and the servo motor and the drive wheel can be driven by a synchronous pulley and a synchronous belt.

[0029] like Figure 3As shown, in this embodiment, the arc-shaped track assembly 3 includes an arc-shaped track body 31 and four pulleys 32. The four pulleys 32 are all fixedly mounted on the base plate 1 by bolts and nuts. Two pulleys 32 are spaced apart at the upper end of the arc-shaped track body 31, and the other two pulleys 32 are spaced apart at the lower end of the arc-shaped track body 31. The driven arc-shaped gear 23 has the same shape and curvature as the arc-shaped track body 31, and is fixedly mounted on the arc-shaped track body 31, driving the arc-shaped track body 31 to rotate. The pulleys 32 abut against the upper or lower end face of the arc-shaped track body 31 respectively, and move relative to the arc-shaped track body 31 during its rotation. This is to prevent the arc-shaped track body 31 and the driven arc-shaped gear 23 from wobbling or swaying during rotation, so that the driven arc-shaped gear 23 is in a stable state during rotation, thereby improving the rotational stability of the rubber valve 4. At the same time, it can also limit and define the movement or rotation path of the arc-shaped track body 31, the driven arc-shaped gear 23 and the rubber valve 4, thereby achieving precise control of the rotation angle of the rubber valve 4. In other embodiments, the arc-shaped track assembly 3 may include at least three pulleys 32. When the arc-shaped track assembly 3 includes three pulleys 32, these three pulleys 32 are respectively disposed at the upper and lower ends of the arc-shaped track body 31, and are all located near the center of the substrate 1. The three pulleys 32 abut against the upper and lower end faces of the arc-shaped track body 31, and move relative to the arc-shaped track body 31 during rotation. This ensures that the arc-shaped track body 31 and the driven arc-shaped gear 23 remain stable during movement, and restricts the movement path of the arc-shaped track body 31 and the driven arc-shaped gear 23, thereby achieving precise control of the rotation angle of the glue valve 4. Furthermore, the pulleys 32 may be fixed to the substrate 1 by bolts and nuts, or by other means.

[0030] To further improve the stability of the arc-shaped track assembly 3 during rotation, and thus improve the rotational stability of the glue valve 4, such as... Figure 4 As shown, in this embodiment, the upper and lower ends of the arc-shaped track body 31 are also provided with arc-shaped protrusions 33; correspondingly, the pulley 32 is provided with a groove 34 that matches the shape of the arc-shaped protrusion 33; the arc-shaped protrusion 33 on the arc-shaped track body 31 is embedded in the groove 34 on the pulley 32. In other embodiments, the upper and lower end faces of the arc-shaped track body 31 may also be provided with guide grooves, and the pulley 32 is embedded in the guide groove and moves relative to each other within the guide groove, etc.

[0031] A limiting block 5 is also provided between the glue valve 4 and the connecting block 24; the limiting block 5 is fixedly set on the connecting block 24, and the glue valve 4 is set on the limiting block 5; and the limiting block 5 is provided with an arc-shaped groove that fits the glue valve 4 to accommodate the glue valve 4, so as to avoid the glue valve 4 from tilting or shaking during rotation and continuous glue dispensing, thereby helping to achieve precise control of the rotation angle of the glue valve 4.

[0032] like Figure 5 As shown, the dispensing mechanism can drive the arc-shaped track assembly 3 and the dispensing valve 4 to rotate through the rotary drive module 2, so that the dispensing valve 4 can be in the original working state in the middle, and rotate left or right around the central axis of the arc-shaped track body 31, with a maximum rotation of 45° to the left or right around the central axis; and the rotation path of the dispensing valve 4 is limited by the arc-shaped track assembly 3 to improve the stability of the dispensing valve 4.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and therefore, all changes falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
