[0002] Dispensing devices are commonly used in industrial production to bond different components together, facilitating subsequent operations. For example, in the production of electronic products, round electronic components are frequently encountered. When bonding round electronic components to other parts, a circular dispensing process is required. In this case, the dispensing device's needle needs to rotate 360° to form a circular dispensing trajectory.

[0003] In related technical solutions, the needles on the dispensing device are difficult to adjust after installation, resulting in a fixed dispensing trajectory that cannot meet the dispensing needs of parts of different sizes. Utility Model Content

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0042] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] As described in the background section, the needles on the dispensing devices in related technologies are difficult to adjust after installation, resulting in a fixed dispensing trajectory that cannot meet the dispensing requirements of parts of different sizes. To solve this problem, related technologies have proposed a solution that uses a servo three-axis mechanism to drive the needle movement, thereby adjusting the needle position; however, servo three-axis mechanisms with needle adjustment functions are more expensive than ordinary servo three-axis mechanisms, and the adjustment time is longer and inconvenient.

[0044] In view of this, the embodiments of this application aim to provide a dispensing assembly and dispensing device, which drives the needle to move through a needle adjustment mechanism, thereby changing the distance between the needle and the rotating shaft, so that the length of the needle can be adjusted according to the size of different parts to meet the dispensing requirements of parts of different sizes. This application achieves the adjustment of the needle dispensing trajectory at a relatively low cost.

[0045] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0046] Please refer to Figures 1-3 This embodiment provides a dispensing assembly 10, including:

[0047] A rotating shaft 100 is used to connect to an adhesive supply component 200, and a first adhesive flow channel 110 is provided within the rotating shaft 100. Exemplarily, one end of the rotating shaft 100 may be provided with a valve connector 120, which is used to connect to the adhesive supply component 200, for example, by means of a threaded connection. The adhesive supply component 200 may be, for example, a dispensing valve, which can periodically or continuously inject adhesive into the rotating shaft 100 under the control of a control device, causing the adhesive to enter the first adhesive flow channel 110.

[0048] A drive component 300 is connected to the rotating shaft 100 to drive the rotating shaft 100 to rotate. In this embodiment, the drive component 300 can be, for example, a motor. The drive component 300 can be connected to the rotating shaft through a transmission component. The structure of the transmission component can be set according to needs, such as a gear, pulley, worm gear, or other mechanism.

[0049] A needle 400 is obliquely disposed at one end of the rotating shaft 100 and connected to the first adhesive channel 110. In this embodiment, since the needle 400 is obliquely connected to the rotating shaft 100, when the rotating shaft 100 rotates, the trajectory of the needle 400 is circular, thereby forming a circular dispensing trajectory to meet the requirements of bonding circular electronic components with other components.

[0050] A needle adjustment mechanism 500 connects the rotating shaft 100 and the needle 400. The needle adjustment mechanism 500 moves the needle 400 to change the distance between the needle 400 and the rotating shaft 100. It can be understood that by changing the distance between the needle 400 and the rotating shaft 100, the dispensing trajectory of the needle 400 can be altered. Specifically, when the needle adjustment mechanism 500 moves the needle 400 away from the rotating shaft 100, the length of the needle 400 increases, and the corresponding dispensing trajectory of the needle 400 also becomes larger (i.e., the diameter of the circular dispensing trajectory increases); when the needle adjustment mechanism 500 moves the needle 400 closer to the rotating shaft 100, the length of the needle 400 decreases, and the corresponding dispensing trajectory of the needle 400 also becomes smaller (i.e., the diameter of the circular dispensing trajectory decreases).

[0051] In this embodiment, the needle adjustment mechanism 500 moves the needle 400, thereby changing the distance between the needle 400 and the rotating shaft 100. This allows the length of the needle 400 to be adjusted based on the size of different parts, meeting the dispensing requirements of parts of different sizes. This application achieves adjustment of the needle dispensing trajectory by changing the extension length of the needle 400, resulting in low adjustment costs.

[0052] Please continue to refer to Figure 2 and Figure 3 The needle adjustment mechanism 500 in this embodiment includes:

[0053] The piston body 510 is mounted on the rotating shaft 100. For example, the rotating shaft 100 may be provided with a mounting hole, which may be a threaded hole, and the piston body 510 may be fixed in the mounting hole by means of a threaded connection.

[0054] A piston rod 520 is movably disposed within a piston body 510, and a needle 400 is disposed at the end of the piston rod 520 away from the rotating shaft 100. A second adhesive channel 521 is provided within the piston rod 520, and the second adhesive channel 521 communicates with a first adhesive channel 110. For example, a through hole communicating with the first adhesive channel 110 can be formed on the piston body 510, and the second adhesive channel 521 within the piston rod 520 communicates with the first adhesive channel 110 through this through hole, thereby allowing adhesive to flow into the needle 400 for subsequent dispensing.

[0055] An adjusting component is used to move the piston rod 520 to change the relative position of the piston rod 520 and the piston body 510. It can be understood that since the needle 400 is fixed to the piston rod 520, when the adjusting component moves the piston rod 520, the distance between the needle 400 and the rotating shaft 100 is changed, thereby adjusting the dispensing trajectory of the needle 400.

[0056] Please continue to refer to Figure 2 In one possible implementation, the adjusting member of this embodiment includes an internal thread section disposed in the piston body 510 and an external thread section disposed on the piston rod 520, wherein the piston rod 520 is threadedly connected to the internal thread section in the piston body 510 through the external thread section.

[0057] In this embodiment, when it is necessary to adjust the relative position of the piston rod 520 and the piston body 510, the piston rod 520 can be rotated to extend or retract relative to the piston body 510, thereby changing the distance between the needle 400 and the rotating shaft 100 and adjusting the dispensing trajectory of the needle 400.

[0058] Furthermore, the needle adjustment mechanism 500 of this embodiment also includes a fastener 530, which is threadedly connected to the external thread section and abuts against the piston body 510.

[0059] For example, the fastener 530 in this embodiment can be a nut, which is threaded onto the piston rod 520 and abuts against the piston body 510 to lock the piston rod 520 and the piston body 510 relative to each other. When it is necessary to adjust the relative position of the piston rod 520 and the piston body 510, the fastener 530 can be loosened in advance. After the relative position of the piston rod 520 and the piston body 510 is adjusted to the correct position, the fastener 530 is then tightened to fix it.

[0060] Please continue to refer to Figure 3In another possible embodiment, the adjusting component includes a drive motor 540, an adapter 550, and a connecting rod 560. The drive motor 540 can be fixed to the mounting plate 600 for easy installation and fixation. The output end of the drive motor 540 is connected to the adapter 550, which is sleeved on the rotating shaft 100 and can move along the rotating shaft 100 under the drive of the drive motor 540. The first end of the connecting rod 560 is connected to the adapter 550, and the second end of the connecting rod 560 is connected to the piston rod 520.

[0061] For example, in this embodiment, the drive motor 540 can be connected to the adapter 550 via a mechanism such as a lead screw. When the output end of the drive motor 540 rotates, it can drive the lead screw to rotate, thereby driving the adapter 550 connected to the lead screw to move in a straight line. Since part of the adapter 550 is sleeved on the rotating shaft 100, the adapter 550 can move along the axial direction of the rotating shaft 100. The two ends of the connecting rod 560 can be hinged to the adapter 550 and the piston rod 520 respectively. Since the length of the connecting rod 560 is constant, when the drive motor 540 drives the adapter 550 to move towards the piston rod 520, the connecting rod 560 presses down on the piston rod 520, thereby driving the needle 400 away from the rotating shaft 100, making the length of the needle 400 longer, and the corresponding dispensing trajectory of the needle 400 also larger. When the drive motor 540 drives the adapter 550 to move away from the piston rod 520, the connecting rod 560 pulls the piston rod 520 upward, thereby driving the needle 400 closer to the rotating shaft 100, which shortens the length of the needle 400 and correspondingly reduces the dispensing trajectory of the needle 400.

[0062] In this embodiment, a first sealing ring 570 is provided between the piston rod 520 and the piston body 510. The first sealing ring 570 can seal the gap between the piston rod 520 and the piston body 510 to prevent glue from leaking to the outside of the piston rod 520.

[0063] Please continue to refer to Figure 1 and Figure 3 In this embodiment, the dispensing assembly 10 further includes a mounting plate 600, which is used to connect with other components on the dispensing device, thereby fixing the dispensing assembly 10 onto the dispensing device. A rotating shaft 100 passes through the mounting plate 600 to connect to the adhesive supply component 200. A driving component 300 is disposed on the mounting plate 600, and the output end of the driving component 300 is connected to the rotating shaft 100 via a transmission component. The transmission component includes a driving gear 710 and a driven gear 720. The driving gear 710 is sleeved on the output end of the driving component 300, and the driven gear 720 is sleeved on the rotating shaft 100. The driving gear 710 and the driven gear 720 mesh with each other.

[0064] For example, the driving component 300 and the transmission component can be respectively disposed on both sides of the mounting plate 600. The output end of the driving component passes through the mounting plate 600 and is connected to the drive gear 710. When the driving component 300 rotates, the drive gear 710 can drive the passive gear 720 to rotate synchronously, thereby driving the rotating shaft 100 fixedly connected to the passive gear 720 to rotate, so that the needle 400 forms a circular dispensing trajectory.

[0065] Furthermore, in this embodiment, a bushing 130 is also fitted on the rotating shaft 100. The bushing 130 is used to position the rotating shaft 100 to prevent the rotating shaft 100 from tilting when it rotates.

[0066] In this embodiment, a second sealing ring 140 is provided between the valve connector 120 and the rotating shaft 100. The second sealing ring 140 is used to seal the gap between the valve connector 120 and the rotating shaft 100 to prevent glue from leaking to the outside of the rotating shaft 100.

[0067] Please refer to Figure 4 This embodiment also provides a dispensing device, including a frame 20, a conveyor belt 30, and a clamp 40. The conveyor belt 30 passes through the frame 20, and the clamp 40 is disposed on the conveyor belt 30. A servo three-axis mechanism 21 is provided on the frame 20. The servo three-axis mechanism 21 is connected to the dispensing assembly 10 and can drive the dispensing assembly 10 to move in three-dimensional space.

[0068] Specifically, the structure of the frame 20 in this embodiment can be configured as needed. For example, it can be formed by connecting multiple rods end to end to create a generally polygonal prism-shaped structure. The conveyor belt 30 can be threaded through the frame 20 to connect different workstations before and after dispensing. The clamp 40 is fixedly mounted on the conveyor belt 30 and can move with the conveyor belt 30. The clamp 40 can hold the part to be dispensed or the tray containing the part to be dispensed for dispensing operations. The servo three-axis mechanism 21 mounted on the frame 20 can drive the dispensing assembly 10 to move in three-dimensional space. For example, the servo three-axis mechanism 21 may include three motors, which control the movement of the dispensing assembly 10 in three different directions, thereby enabling the dispensing assembly 10 to move in three-dimensional space. The servo three-axis mechanism 21 can drive the dispensing assembly 10 closer to the clamp 40 to perform dispensing operations on the parts within the clamp 40.

[0069] It is understood that, due to the use of the aforementioned dispensing assembly 10 in this embodiment, when the size of the part within the fixture 40 changes, the needle can be moved via the needle adjustment mechanism, thereby changing the distance between the needle and the rotating shaft, thus adjusting the needle length without needing to adjust the trajectory of the three-axis mechanism. This can meet the dispensing requirements for parts of different sizes. This application achieves adjustment of the needle dispensing trajectory by changing the extension length of the needle, resulting in lower adjustment costs. Compared to adjusting the three-axis mechanism to change the dispensing trajectory, the above-mentioned method of adjusting the dispensing trajectory reduces the difficulty of debugging the dispensing trajectory and lowers the tolerance requirements of each link in the dimensional chain.
