Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment, and in particular to a dispensing positioning structure with precise multi-axis adjustment characteristics. Background Technology

[0002] Dispensing equipment, also known as glue applicator or glue dispenser, is an industrial automation device that uses air pressure to control fluids (such as glue or paint) to achieve precise dispensing, spraying, and pouring processes. It is mainly used in fields such as electronics manufacturing, automotive industry, medical devices, and new energy.

[0003] In existing technologies, especially for products with precision dispensing requirements, different dispensing mechanisms exist for different dispensing needs. Therefore, the current practice is to replace dispensing components of different specifications with each other. For example, transitioning from large-size dispensing to small-size dispensing involves replacing the dispensing component with a smaller one to accommodate the precision dispensing of small-sized products.

[0004] The above-mentioned dispensing adaptation method is inefficient. Each component needs to be assembled one by one, which takes a long time, is difficult to control tolerances, and results in inconsistent dispensing precision.

[0005] In view of this, this technical solution proposes a dispensing positioning structure with precise multi-axis adjustment characteristics. It adopts a multi-axis movable component that can be adjusted instantly after assembly, and is combined with a precise scale adjustment device to achieve rapid adjustment and accurate dispensing action. Utility Model Content

[0006] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a dispensing positioning structure with precise multi-axis adjustment characteristics, thereby addressing the problem that existing dispensing mechanisms lack real-time precise adjustment and control.

[0007] To achieve the above objectives, this utility model provides a dispensing positioning structure with precise multi-axis adjustment characteristics, comprising a mounting base body composed of a translational main shaft and a dual-axis adjustment assembly. The translational spindle includes a spindle guide rail mounted on the X-axis and a slide that runs on the spindle guide rail. The dual-axis adjustment assembly includes a base frame connected to the slide block. The base frame opens upward to form a bottom groove, and a limiting head is formed on one side of the bottom groove. An inverted Y-axis movable frame is provided on the base frame. The downward opening of the Y-axis movable frame forms a Y-axis movable groove, and the limiting head is located within the Y-axis movable groove. A Y-axis telescopic adjustment device is provided at one end of the base frame. The Y-axis telescopic head of the Y-axis telescopic adjustment device passes through the base frame and connects to one end of the Y-axis movable frame. A Z-axis movable frame is provided on the outside of the other end of the Y-axis movable frame. The Z-axis movable frame opens to one side to form a Z-axis movable groove. The upper and lower ends of one side of the Y-axis movable frame are located within the Z-axis movable groove. A Z-axis telescopic adjustment device is provided at the bottom of the Z-axis movable frame. The Z-axis telescopic head of the Z-axis telescopic adjustment device passes through the bottom of the Z-axis movable frame and connects to the bottom of one end of the Y-axis movable frame. A connecting part is formed on the top surface of the Z-axis movable frame. The Y-axis telescopic adjustment device and the Z-axis telescopic adjustment device are both telescopic adjustment mechanisms with scales.

[0008] As a further embodiment of this utility model, the spindle guide rail is laid on a spindle base plate with mounting holes.

[0009] As a further embodiment of this utility model, a lead screw parallel to the spindle guide rail is provided on one side of the spindle base plate, and a connector is formed at one end of the base frame, with a through hole sleeved on the lead screw on the connector.

[0010] As a further embodiment of this utility model, both the Y-axis telescopic adjustment device and the Z-axis telescopic adjustment device are micrometer handles.

[0011] As a further embodiment of this invention, the number of dual-axis adjustment components operating on the main spindle guide rail is at least two.

[0012] As a further embodiment of this utility model, a fixing seat with fixing holes extends from one side of the bottom of the spindle base plate.

[0013] As a further embodiment of this utility model, the Y-axis movable frame, the bottom frame, and the Z-axis movable frame are all integral vertically bent and perforated metal frame plate structures.

[0014] As a further embodiment of this utility model, the bottom of the base frame is recessed inward to form a fixing groove for sliding into and assembling with the slide block.

[0015] The beneficial effects of this utility model are as follows: This technical solution effectively solves the problem that traditional dispensing mechanisms cannot perform real-time precision adjustments by combining the translational main shaft with the dual-axis adjustment components.

[0016] Specifically, the dispensing head (or other functional components) is mounted on the connecting part on the top surface of the Z-axis movable frame. One-dimensional positioning is achieved by the movement of the slide on the X-axis spindle guide rail. Through a unique nested frame structure and the cooperation of a limiting head, which drives the Y-axis and Z-axis telescopic adjustment devices respectively, the position of the dispensing head along the Y-axis (front / back) and Z-axis (up / down) can be independently and precisely controlled. Since both the Y-axis and Z-axis telescopic adjustment devices are graduated adjustment mechanisms, operators can directly perform intuitive and quantitative fine-tuning, achieving rapid and precise positioning in three axes. This allows for adaptation to different dispensing specifications without replacing components, significantly improving the accuracy, efficiency, and adaptability of dispensing operations.

[0027] Please see the appendix Figure 1-6 , This technical solution provides a dispensing positioning structure with precise multi-axis adjustment characteristics. The connecting structure includes a mounting body (1) consisting of a translational main shaft (11) and a dual-axis adjustment assembly (12). The translational main shaft (11) consists of a main shaft guide rail (111) set in the X-axis direction and a slide (112) running on the main shaft guide rail (111). The slide (112) drives the entire dual-axis adjustment assembly (12) to translate in the X-axis. The dual-axis adjustment assembly (12) is connected to the slide (112) through a bottom frame (120). The bottom frame (120) opens upward to form a bottom groove (1200), and a limiting head (1202) is provided on one side of the bottom groove (1200). An inverted Y-axis movable frame (121) is installed on the bottom frame (120). The Y-axis movable frame (121) opens downward to form a Y-axis movable groove (1210). The head (1202) is embedded in the Y-axis movable slot (1210), thereby limiting the excessive movement of the Y-axis movable frame (121) in the X-axis direction. A Y-axis telescopic adjustment device (122) is installed at one end of the bottom frame (120). Its Y-axis telescopic head (1220) passes through the bottom frame (120) and is connected to one end of the Y-axis movable frame (121). By rotating the Y-axis telescopic adjustment device (122), the forward and backward movement of the Y-axis movable frame (121) on the Y-axis can be precisely controlled. A Z-axis movable frame (123) is provided on the outside of the other end of the Y-axis movable frame (121). The Z-axis movable frame (123) opens to one side to form a Z-axis movable slot (1230). The upper and lower ends of one side of the Y-axis movable frame (121) are embedded in the Z-axis movable slot (1230), so that the Z-axis movable frame (123) can move relative to the Y-axis movable frame (121) in the Z-axis direction. The bottom of the Z-axis movable frame (123) is equipped with a Z-axis telescopic adjustment device (124). Its Z-axis telescopic head (1240) passes through the bottom of the Z-axis movable frame (123) and connects to the bottom of one end of the Y-axis movable frame (121). Rotating the Z-axis telescopic adjustment device (124) can drive the Z-axis movable frame (123) to move up and down on the Z-axis. The top surface of the Z-axis movable frame (123) is provided with a connecting part (1231) for fixing the dispensing head or other functional components. Both the Y-axis telescopic adjustment device (122) and the Z-axis telescopic adjustment device (124) adopt a telescopic adjustment mechanism with scale, such as a micrometer handle, to ensure the accuracy and repeatability of the adjustment.

[0028] The beneficial effect is that, through the improvement of this solution, the dispensing head can be adjusted in real time and precisely in the X, Y, and Z directions (mainly in the Y and Z axes, while the X axis can be precisely positioned by a servo motor), without the need to replace dispensing parts of different specifications, thus significantly improving dispensing efficiency and accuracy.

[0029] Specifically, firstly, the entire dual-axis adjustment assembly (12) runs on the spindle guide rail (111) via the slide (112), that is, it moves in translation along the X-axis. The connecting part (1231) of the dual-axis adjustment assembly (12) is used to assemble the dispensing head (or other functional components). Generally, after assembly, the connecting part (1231) faces downward. When it is necessary to adjust the front and back position of the dispensing head, that is, along the Y-axis, rotate the Y-axis telescopic adjustment device (122). At this time, the Y-axis telescopic head (1220) can control the operation of the Y-axis movable frame (121). Since there is a limit head (1202) inside the Y-axis movable frame (121), that is, one end of the bottom frame (120), the operation of the Y-axis movable frame (121) can be limited in the X-axis by the limit head (1202). The bottom of one end of the Y-axis movable frame (121) is connected to the Z-axis telescopic head (1240), and the outside of the Z-axis telescopic head (1240) is connected to the Z-axis movable frame (123). Therefore, after rotating the Y-axis telescopic adjustment device (122), it will drive the Z-axis movable frame (123) and the dispensing head connected to the connecting part (1231) to move back and forth in the Y-axis direction. When the vertical position of the dispensing head needs to be adjusted, the Z-axis telescopic adjustment device (124) is rotated. At this time, since the middle position of the Z-axis telescopic head (1240) connected to the Z-axis telescopic adjustment device (124) is fixed to the bottom of the Z-axis movable frame (123), and the top of the Z-axis telescopic head (1240) is connected to the bottom of one end of the Y-axis movable frame (121), rotating the Z-axis telescopic adjustment device (124) will drive the Z-axis movable frame (123) and the dispensing head connected to the connecting part (1231) to move up and down in the Z-axis direction.

[0030] Among them, the Y-axis telescopic adjustment device (122) and the Z-axis telescopic adjustment device (124) are both adjustment devices with precise scales. They enable quick and intuitive adjustment of the dispensing position. The scale-type adjustment device allows operators to fine-tune and lock the position, avoiding assembly errors and time waste caused by component replacement in traditional methods. This ensures the consistency and reliability of the dispensing process and is particularly suitable for fields such as electronic manufacturing and medical devices that require high-precision dispensing.

[0031] Reference Appendix Figure 3 As a preferred embodiment of the present invention, the spindle guide rail (111) in this solution is laid on a spindle base plate (110) with mounting holes, and the entire mounting base is fixed to external machine tools or other fixed parts through the mounting holes on the spindle base plate (110).

[0032] In addition, in practical applications, similar stabilizing effects can also be achieved by using simple installation structures such as directly fixing the spindle guide rail (111) with a clamping device or using a magnetic base.

[0033] Reference Appendix Figure 3As a preferred embodiment of this utility model, this solution provides a lead screw (113) parallel to the spindle guide rail (111) on one side of the spindle base plate (110). At the same time, a connector (1203) is provided at one end of the bottom frame (120). The connector (1203) has a through hole (1204) and is directly sleeved on the lead screw (113), which makes the component run more smoothly and the force is more uniform in the X-axis direction, preventing shaking or jamming that may occur during translation, and ensuring the positioning accuracy of the dispensing head during long-distance movement.

[0034] Understandably, this is only one preferred combination of drive and guidance. Other transmission structures can also be used to achieve smooth movement, such as using a synchronous belt with a guide rail or direct drive by a linear motor, which can also make it run stably.

[0035] Reference Appendix Figure 3-5 In a preferred embodiment of this utility model, both the Y-axis telescopic adjustment device (122) and the Z-axis telescopic adjustment device (124) preferably employ a micrometer handle. Operators can directly and precisely control the extension or retraction of the Y-axis telescopic head (1220) and the Z-axis telescopic head (1240) by rotating the micrometer handle with precise graduations. This allows for micron-level fine adjustment of the dispensing head's position in the Y and Z axes, resulting in an intuitive, stable, and highly repeatable adjustment process. Of course, the micrometer is only a preferred option; other adjustment mechanisms with similar precision (such as digital micrometer heads or high-precision servo electric actuators) can also be used for the Y-axis telescopic adjustment device (122) and the Z-axis telescopic adjustment device (124).

[0036] Reference Appendix Figure 1 , 2 3, 5. As a preferred embodiment of this utility model, the dual-axis adjustment component (12) in this solution can be configured as a set of two, with the two dual-axis adjustment components (12) arranged side by side on the translational main shaft (11), which can simultaneously perform dual-axis precision adjustable dispensing actions for two products. The specific number of components can be increased according to the actual processing situation.

[0037] Reference Appendix Figure 3 In a preferred embodiment of this invention, a mounting base (10) with a fixing hole (100) extends from one side of the bottom of the spindle base plate (110). The structure of the mounting base (10) is usually narrower than the spindle base plate (110) itself, and the mounting body (1) can be installed in a relatively narrow position on the fixing surface through the mounting base (10). The mounting base (10) is detachable from the spindle base plate (110).

[0038] Reference Appendix Figure 5As a preferred embodiment of the present invention, the Y-axis movable frame (121), the bottom frame (120) and the Z-axis movable frame (123) are preferably made of a metal frame plate structure formed by vertical bending and drilling. Each frame is formed by bending a single metal plate, which has high structural strength and rigidity and can resist deformation. At the same time, the pre-set holes on it facilitate the precise installation and connection of other components such as telescopic adjustment devices.

[0039] Reference Appendix Figure 4 As a preferred embodiment of the present invention, the bottom of the base frame (120) is recessed inward to form a fixing groove (1201). The base frame (120) can be quickly assembled with the slide block (112) on the translational running spindle (11) by sliding in. After assembly, it is fastened by fasteners such as screws.

[0040] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0041] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0042] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure.
