Description

Technical Field

[0001] This utility model belongs to the field of motor equipment technology, and in particular relates to an inclined dispensing device. Background Technology

[0002] Dispensing equipment is a coating tool used in automated industries for precise control of fluids (such as adhesives). Driven by pneumatic pressure or mechanical control, it achieves precise droplet application and coating of fluid onto the surface of a workpiece. Dispensing equipment is widely used in electronics, automotive, and home appliance industries to improve production efficiency and ensure product quality.

[0003] Chinese patent document CN118950383A discloses a multi-angle dispensing positioning adjustment machine. The adjustment machine includes a base and a worktable set on the base. Two columns are vertically arranged on the worktable. An X-axis module is fixedly installed on the two columns. A Z-axis module is movably arranged on the X-axis module. A dispensing mechanism is fixedly installed on the Z-axis module. A Y-axis module is arranged on the worktable between the two columns. A workpiece rotation module is provided on the Y-axis module. The workpiece rotation module includes a fixed base plate and a flip motor base fixedly installed at either end of the fixed base plate. A flip motor is fixedly installed on the flip motor base. The output end of the flip motor passes through the flip motor base and is fixedly connected to a connecting shaft. The end of the connecting shaft away from the flip motor is fixedly connected to a horizontal rotation motor base. A horizontal rotation motor is fixedly installed on the horizontal rotation motor base. The output end of the horizontal rotation motor passes through the horizontal rotation motor base and is fixedly connected to a fixture base for placing the watch case. When performing dispensing on workpieces, the workpiece is simply fixed on the workpiece rotating module using a corresponding workpiece fixture. The dispensing and movement of the workpiece and the dispensing dropper are controlled by a PLC controller. By setting up the workpiece rotating module, which uses a flip motor and a flat motor to drive the fixture seat to rotate and flip, multi-angle processing of the workpiece is achieved on a single dispensing mechanism.

[0004] The technical solution disclosed in the aforementioned patent documents uses a rotating module with a flip motor and a flat motor to drive the fixture to rotate and flip, thereby achieving multi-angle dispensing to meet practical dispensing needs. However, the dispensing mechanism remains vertical and can only dispense adhesive vertically. When it is necessary to dispense adhesive at an angle to the part, the adhesive needs to present different angles. Especially for ring-shaped dispensing that requires tilting, the aforementioned patent documents are difficult to implement. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of the tilting dispensing device of this utility model, please refer to... Figures 1 to 4The tilting dispensing device of this embodiment can adjust the tilt angle of the dispensing nozzle, thereby adjusting the width of the adhesive and ensuring uniform dispensing onto the tilted surface. Specifically, the tilting dispensing device includes a support base 100, a first translation mechanism 200, a second translation mechanism 300, a mounting base 400, a lifting drive mechanism 500, a lifting seat 600, a rotation drive mechanism 700, a connecting base 800, an adjusting base 900, and a dispensing cylinder 10. The first translation mechanism 200 is located at the upper end of the support base 100, and the second translation mechanism 300 is located on the first translation mechanism 200 and perpendicular to the drive trajectory of the first translation mechanism 200. The mounting base 400 is connected to the moving end of the second translation mechanism 300, the lifting drive mechanism 500 is located on one side of the mounting base 400, and the lifting seat 600 is connected to the lifting drive mechanism 500. A rotary drive mechanism 700 is mounted on a lifting seat 600. The rotary drive mechanism 700 includes a rotating shaft 710. A first connecting part 810 is provided on one side of the upper end of a connecting seat 800, and a second connecting part 820 is provided on one side of the lower end. The first connecting part 810 is connected to the rotating shaft 710. The second connecting part 820 has a transition position 821 and an arc-shaped groove 822. The center of the arc-shaped groove 822 coincides with the transition position 821. An adjusting seat 900 is rotatably connected to the transition position 821. The adjusting seat 900 is provided with a locking member 910 that extends into the arc-shaped groove 822 to lock the adjusting seat 900 on one side of the second connecting part 820. The adjusting seat 900 has a clamping position 901, in which a dispensing cylinder 10 is clamped. A dispensing needle 11 is provided at the bottom end of the dispensing cylinder 10. Specifically, the first translation mechanism 200, the second translation mechanism 300, and the lifting drive mechanism 500 are all electric lead screw linear modules.

[0028] The tilting dispensing device of this embodiment can drive the dispensing cylinder to move along a set trajectory via the first translation mechanism 200 and the second translation mechanism 300, thus causing the dispensing needle 11 to dispense glue along the set trajectory. Furthermore, the rotation shaft 710 of the rotation drive mechanism 700 can be rotated, thereby rotating the dispensing needle 11 and adjusting the dispensing direction, thus enabling both linear and curved trajectory dispensing. When it is necessary to adjust the tilt angle of the glue dispensing, the locking member 910 can be loosened, causing the adjusting seat 900 to rotate around the transition position 821, thereby adjusting the tilt angle of the dispensing cylinder 10 and the dispensing needle 11, thus achieving different angle adjustments and dispensing to meet actual dispensing needs.

[0029] Furthermore, refer to Figure 3 and Figure 4A protrusion 801 extends from one side of the lower end of the connecting seat 800. The protrusion 801 has a screw hole, and the screw hole has a support screw 802. An arc-shaped notch 902 is provided on the side of the adjusting seat 900, and the end of the support screw 802 abuts against the arc-shaped notch 902. In this embodiment, when adjusting the tilt angle of the adjusting seat 900, the locking member 910 can be used to keep the adjusting seat 900 and the second connecting part 820 in a pre-tight state. Then, by rotating the support screw 802, the supporting screw 802 pushes the adjusting seat 900 to rotate. When the adjusting seat 900 rotates, the end of the support screw 802 cooperates with the arc-shaped notch 902, reducing friction and allowing for better angle adjustment.

[0030] Furthermore, v refers to Figure 2 and Figure 3 The second connecting part 820 is provided with two concentric arc-shaped grooves 822, each of which is fitted with a locking member 910. A connecting plate 920 is provided between the two locking members 910. The connecting plate 920 has a through hole, and a pointer 921 is provided on the top side of the through hole. The second connecting part 820 is also provided with a scale plate 823. In this embodiment, two sets of arc-shaped grooves 822 are provided to make the connection of the adjusting seat 900 more stable. When adjusting the angle of the adjusting seat 900, the pointer 921 can be used in conjunction with the scale plate 823 to accurately adjust the tilt angle of the dispensing cylinder 10.

[0031] Furthermore, refer to Figure 1 and Figure 2 The support base 100 is also provided with a fixing base 110 on one side of its lower end. The fixing base 110 is equipped with an electric brush 120 for cleaning residual glue on the dispensing needle 11. After the dispensing needle 11 finishes dispensing, it can be moved above the electric brush 120, and the electric brush 120 can clean the residual glue on the dispensing needle 11, thereby keeping the dispensing needle 11 clean.

[0032] Furthermore, refer to Figure 3 The support base 100 also has a pad 130 on one side of its lower end. A dispensing test platform 140 is mounted on the pad 130. The dispensing test platform 140 has a center and linear graduations 141 along the center. In this embodiment, before dispensing glue to the product, the dispensing needle 11 can be moved to the center position and dispensing glue on the dispensing test platform 140. Simultaneously, the rotation drive mechanism 700 drives the dispensing needle 11 to rotate. Based on the dispensing situation, it can be directly determined whether the dispensing needle 11 is on the rotation axis of the rotation shaft 710, thereby allowing adjustment of the dispensing position of the dispensing needle 11.

[0033] Furthermore, referring to Figure 3The pad 130 is also equipped with an elastic ejector pin 150, and a photoelectric sensor 160 is located at the bottom end of the pad 130. The bottom end of the elastic ejector pin 150 extends above the photoelectric sensor 160. In this embodiment, it is used to determine the zero point position of the dispensing needle 11. Specifically, the lifting drive mechanism 500 drives the dispensing needle 11 to descend and squeeze the elastic ejector pin 150. The lower end of the elastic ejector pin 150 triggers the photoelectric sensor 160, thus determining the zero point position of the dispensing needle 150. This ensures subsequent dispensing height control.

[0034] Furthermore, refer to Figure 1 and Figure 2 The bottom end of the rotating shaft 710 is also provided with a cross-shaped adjusting slide 720, and the first connecting part 810 is connected to the bottom of the cross-shaped adjusting slide 720. When there is a deviation in the dispensing position of the dispensing needle 11, it can be adjusted by the cross-shaped adjusting slide 720.

[0035] Furthermore, refer to Figure 2 The rotary drive mechanism 700 also includes a motor 701 and a synchronous belt assembly 702. The upper end of the lifting seat 600 is provided with a support plate 610, the motor 701 is mounted on the support plate 610, and the rotating shaft 710 rotatably passes through the support plate 610. The synchronous belt assembly 702 connects the motor 701 and the rotating shaft 710. The bottom end of the rotating shaft 710 is provided with a connecting flange 711, and the first connecting part 810 is connected to the bottom of the connecting flange 711.

[0036] Furthermore, refer to Figure 2 , Figure 5 and Figure 6 The bottom of the connecting flange 711 is also provided with a connector 730. The top side of the connector 730 is provided with a cavity 731, and one side of the connector 730 is provided with a through hole 732 communicating with the cavity 731. The interior of the rotating shaft 710 is provided with an air passage 712 that runs through both the upper and lower ends. The upper end of the air passage 712 is provided with a first pipe connector 713, and the bottom end is provided with a second pipe connector 714. The first pipe connector 713 is connected to the air pipe of the dispensing air source control device (shown in the attached figure), and the second pipe connector 714 is connected to the air pipe of the dispensing cylinder 10. Specifically, the air pipe connecting the second pipe connector 714 and the dispensing cylinder 10 passes through the through hole 732 and connects to the dispensing cylinder 10. The cavity 731 on the top side of the connector 730 facilitates the air pipe passing through the through hole, making dispensing more convenient. In this embodiment, during the dispensing process, the dispensing air source control device applies air pressure to the dispensing cylinder 10, causing the glue inside the dispensing cylinder 10 to be squeezed out from the dispensing needle 11. By placing the air pipe connecting the air source inside the rotating shaft 710, the structure becomes more compact, and the problem of air pipe entanglement is avoided when the rotating shaft 710 drives the dispensing cylinder 10 to rotate.

[0037] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
