Abstract
Description
Technical Field
[0001] This application relates to the field of circuit board dispensing technology, and in particular to an automatic circuit board dispensing device. Background Technology
[0002] PCB dispensing is a common processing technique widely used in the electronics industry, particularly for component mounting, circuit protection, and circuit isolation. Dispensing fills tiny gaps and cracks on PCBs, primarily enhancing their sealing, weather resistance, and mechanical strength. Traditional dispensing machines, including desktop and semi-automatic models, require manual installation of the PCB on a fixture before dispensing. The PCB is then removed from the fixture. This semi-automatic process has limited efficiency and is currently unsuitable for automated production lines. Utility Model Content
[0003] To address the aforementioned technical problems, this application provides a circuit board dispensing device, comprising a worktable, a turntable rotatably mounted on the worktable, and a plurality of support fixtures arranged in a ring on the turntable for supporting circuit boards. A movable module is mounted on the worktable above the turntable, and a dispensing assembly is mounted on the execution end of the movable module. A pressing assembly is mounted on one side of the worktable near the turntable, and the pressing assembly is used to fix the circuit board in the support fixtures.
[0004] Preferably, the pressing component includes a support plate, a lifting driver mounted on the support plate, and a pressure block provided at the driving end of the lifting driver.
[0005] Preferably, the support fixture has a receiving groove that matches the shape of the circuit board.
[0006] Preferably, the moving module includes a gantry frame, a first drive module disposed on the gantry frame, and a second drive module disposed on the first drive module. The first drive module drives the second drive module to move in the horizontal direction, and the second drive module drives the dispensing assembly to move in the vertical direction.
[0007] Preferably, the dispensing assembly includes a rotating component disposed at the driving end of the second driving module and a dispensing cylinder disposed on the rotating component, the rotating component being used to drive the dispensing cylinder to rotate.
[0008] Preferably, through-beam sensors are provided on both sides of the pressing assembly on the worktable.
[0009] Preferably, it further includes a drive assembly disposed within the worktable, the drive assembly being used to drive the turntable to rotate.
[0010] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By setting a turntable on the workbench, and having several support fixtures arranged in a ring on the turntable for supporting circuit boards, a moving module is set on the workbench above the turntable, and a dispensing component is set at the execution end of the moving module. The moving module drives the dispensing component to move above the turntable, thereby enabling the dispensing component to align with the circuit boards on the support fixtures for dispensing. At the same time, a pressing component is set on one side of the turntable on the workbench. As the turntable rotates, the support fixture containing the circuit boards rotates to the underside of the pressing component. The pressing component fixes the circuit boards in the support fixtures, and then the dispensing component dispenses the circuit boards. The turntable then transfers the dispensed circuit boards to the other side for unloading, thereby realizing automatic dispensing. This method can be applied to automated production lines for fully automated production, improving production efficiency. Attached Figure Description

[0014] 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 only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0015] Example
[0016] To address the aforementioned technical problems, this embodiment provides an automatic dispensing device for circuit boards, such as... Figure 1-2As shown, the system includes a worktable 10 and a turntable 20 rotatably mounted on the worktable 10. Several support fixtures 30 are arranged in a ring on the turntable 20, and the support fixtures 30 are used to support circuit boards. A moving module 50 is positioned on the worktable 10 above the turntable 20. A dispensing assembly 40 is mounted on the actuating end of the moving module 50. The moving module 50 drives the dispensing assembly 40 to move above the turntable 20, thereby allowing the dispensing assembly 40 to dispense adhesive onto the circuit boards on the support fixtures 30. Simultaneously, the dispensing assembly 40 is positioned on the worktable 10... A pressing component 60 is provided on one side of the turntable 20, and the pressing component 60 is located above one of the support fixtures 30. The turntable 20 rotates, causing the support fixture 30 containing the circuit board to rotate under the pressing component 60. The pressing component 60 fixes the circuit board in the support fixture 30. Then, the dispensing component 40 dispenses glue onto the circuit board. The turntable 20 then transfers the glued circuit board to the other side for unloading, thereby realizing automatic dispensing. It can be applied to automated production lines for fully automated production and improve production efficiency.
[0017] Specifically, the support fixture 30 has a receiving groove that matches the shape of the circuit board. The circuit board can then be placed in the receiving groove of the support fixture 30. To fix the circuit board onto the support fixture 30, the pressing assembly 60 includes a support plate 62 and a lifting driver 63 mounted on the support plate 62. A pressure block 61 is provided at the driving end of the lifting driver 63. For example, the lifting driver 63 can be a cylinder, which drives the pressure block 61 to press down on the circuit board, thus fixing the circuit board onto the support fixture 30 and ensuring that it does not shift during the dispensing process. In some embodiments, the pressure block 61 can be U-shaped, allowing it to act on the two sides of the circuit board near the end, preventing obstruction and interference during dispensing.
[0018] Furthermore, a drive assembly, which can be a motor, is provided within the workbench 10 to drive the turntable 20 to rotate. For example, four support fixtures 30 are arranged in a ring on the turntable 20. In some embodiments, during automated production, a robotic arm can pick up the circuit board and load it onto the support fixtures 30 of the turntable 20. The turntable 20 then rotates the support fixtures 30 containing the circuit board under the pressing assembly 60, which fixes the circuit board in the support fixtures 30. Then, the dispensing assembly 40 dispenses adhesive onto the circuit board. After dispensing, the turntable 20 moves the circuit board to a side away from the pressing assembly 60, where a robotic arm can unload the circuit board, thus achieving automated dispensing and avoiding the need for manual fixing of the circuit board to the fixtures in existing semi-automatic production, thereby improving production efficiency. Furthermore, through-beam sensors 11 are provided on both sides of the pressing assembly 60 on the worktable 10, and grooves are provided on both sides of the support fixture 30. The light from the through-beam sensors 11 can pass through the grooves. When the turntable 20 rotates the support fixture 30 containing the circuit board to below the pressing assembly 60, the light is blocked by the circuit board inside the support fixture 30. Thus, the through-beam sensors 11 sense that the support fixture 30 is in place and that there is a circuit board inside the support fixture 30, and the pressing and fixing and dispensing operations can begin.
[0019] Furthermore, in the above scheme, the moving module 50 includes a gantry 51, a first drive module 52 mounted on the gantry 51, and a second drive module 53 mounted on the first drive module 52. The first drive module 52 drives the second drive module 53 to move horizontally, and the second drive module 53 drives the dispensing assembly 40 to move vertically. Both the first drive module 52 and the second drive module 53 can be linear drive modules composed of a motor, a slide table, and a lead screw. The first drive module 52 is placed horizontally, and can then move horizontally via the second drive module 53 and the dispensing assembly 40. The second drive module 53 is placed vertically, and can then drive the dispensing assembly 40 to move up and down, thereby enabling movement above the turntable 20 to dispense adhesive onto the circuit board. Alternatively, a third drive module can be mounted on the worktable 10, with the gantry 51 mounted at the drive end of the third drive module. The third drive module is perpendicular to the first drive module 52, allowing the dispensing assembly 40 to move along three axes.
[0020] Furthermore, the dispensing assembly 40 includes a rotating assembly 42 disposed at the drive end of the second drive module 53, and a dispensing cylinder 41 disposed on the rotating assembly 42. The rotating assembly 42 is used to drive the dispensing cylinder 41 to rotate. The drive end of the second drive module 53 is provided with a connecting plate. The second drive module 53 drives the connecting plate to move up and down. The rotating assembly 42 is disposed on the connecting plate, and the dispensing cylinder 41 is disposed on the rotating assembly 42. The rotation axis of the rotating assembly 42 is horizontal, thereby driving the dispensing cylinder 41 to rotate around the horizontal axis, thus more sensitively dispensing adhesive to the circuit board on the worktable 10. For example, the rotating assembly 42 may be composed of a motor, gears, and a rotating shaft. The rotating shaft is connected to the dispensing cylinder 41, and the motor drives the rotating shaft to rotate through the gears, thereby achieving the purpose of driving the dispensing cylinder 41 to rotate.
[0021] In summary, the solution of this application sets a turntable on the workbench, on which several carrier fixtures are arranged in a ring to support the circuit board. A moving module is set above the turntable on the workbench, and a dispensing component is set at the execution end of the moving module. The moving module drives the dispensing component to move above the turntable, so that the dispensing component can be aligned with the circuit board on the carrier fixture to dispense glue. At the same time, a pressing component is set on one side of the turntable on the workbench. When the turntable rotates, the carrier fixture containing the circuit board rotates to the underside of the pressing component. The pressing component fixes the circuit board in the carrier fixture, and then the dispensing component dispenses glue onto the circuit board. The turntable then transfers the glued circuit board to the other side for unloading, thereby realizing automatic glue dispensing. It can be applied to automated production lines for fully automated production, improving production efficiency.
