Description

Technical Field

[0001] The utility model relates to the technical field of electronic product dispensing equipment, in particular to a dispensing device for a circuit board. Background Art

[0002] In the manufacturing process of circuit boards, using dispensing technology to fix and protect electronic components is a common and important process. Especially for multi-panel circuit boards, in order to improve production efficiency and reduce costs, multiple dispensing valves are usually used for simultaneous operation. The dispensing device includes a base, a dispensing valve, and two relatively arranged side seats on the base. The main purpose of dispensing is to use silicone rubber or other types of glue to fix and protect electronic components and provide electrical insulation, thereby enhancing the reliability and durability of the product.

[0003] The traditional fixing method for multiple dispensing valves often uses screws to fix multiple dispensing valves on a bracket. This fixing method aims to ensure the stability and synchronization of the dispensing valves during operation to achieve higher production efficiency. Although this fixing method meets the production efficiency requirements to a certain extent, it also exposes some obvious disadvantages:

[0004] Poor coordinate consistency caused by fixed position: Once the dispensing valve is fixed, its positions in the three spatial coordinates of X, Y, and Z are locked. When multiple dispensing valves are fixed in the same way, due to factors such as manufacturing tolerances, assembly errors, and equipment wear, the actual positions of multiple dispensing valves deviate from the expected positions, making it difficult to guarantee the spatial coordinate consistency of multiple dispensing valves, which will directly affect the position accuracy of the glue dots on the circuit board.

[0005] Poor adaptability: When the production line needs to switch production or replace circuit boards of different specifications, the fixed positions of the dispensing valves need to be readjusted, which further exacerbates the debugging difficulty and time cost.

[0006] In short, the traditional fixing method improves production efficiency to a certain extent, but its inherent limitations, such as poor consistency and adaptability caused by fixed position, have become the key factors restricting the quality of the circuit board dispensing process and production flexibility. Content of the Utility Model

[0007] To solve the technical problems of poor consistency and adaptability existing in the existing dispensing device, the utility model provides a dispensing device for a circuit board that can quickly adjust the coordinates of the dispensing valve and improve its consistency and adaptability.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] The dispensing device for a circuit board includes a base, a dispensing valve, and two relatively arranged side seats on the base. It also includes a valve seat and a mounting base arranged on the side seats. The dispensing valve is arranged on the valve seat, and the valve seat is arranged on the mounting base. A first slide rail is arranged on the side seat, and a first chute is correspondingly arranged on the mounting base. The mounting base can slide vertically along the first slide rail. At least one end of the side seat close to the base is provided with a second chute, and a second slide rail is correspondingly arranged on the base. At least one side seat can slide along the second slide rail in a direction perpendicular to the sliding direction of the mounting base. A third chute is arranged on the valve seat, and a third slide rail is correspondingly arranged on the mounting base. The valve seat can slide along the third slide rail in a direction perpendicular to both the sliding direction of the side seat and the sliding direction of the mounting base. It further includes a locking mechanism for locking the valve seat and the mounting base, the mounting base and the side seat, and the side seat and the base respectively.

[0010] Furthermore, the locking mechanism includes screws and elongated holes. The elongated holes are respectively arranged on the mounting base, the side seat, and the base. The length directions of the elongated holes are respectively consistent with the sliding directions of the valve seat, the mounting base, and the side seat. The valve seat, the mounting base, and the side seat are all provided with screw holes. The screws pass through the elongated holes and are threadedly connected to the screw holes. When the screws respectively abut against the mounting base, the side seat, and the base, the valve seat is fixed to the mounting base, the mounting base is fixed to the side seat, and the side seat is fixed to the base.

[0011] Furthermore, only one of the two side seats arranged on the base is provided with a second chute, and the other side seat is fixedly arranged on the base. The side seat provided with the second chute can slide along the second slide rail towards or away from the other side seat.

[0012] Furthermore, reinforcing ribs are arranged on the side seats.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Improve the consistency of the dispensing valve position: By setting structures such as the first slide rail and the first chute, the mounting base can slide vertically, so that the height of each dispensing valve can be finely adjusted. The second chute and the second slide rail allow the side seat to move in a direction perpendicular to the sliding direction of the mounting base, and the third chute and the third slide rail allow the valve seat to move in a direction perpendicular to the former two. Such three-dimensional adjustment ability enables the dispensing valve to adapt to different circuit board sizes and layouts, and it is possible to switch production without frequently replacing equipment, enhancing the adaptability of the dispensing device. At the same time, it also reduces the coordinate inconsistency problems caused by factors such as manufacturing tolerances and assembly errors. In addition, the setting of the locking mechanism enables the operator to quickly lock or unlock each component, greatly reducing the adjustment time and labor costs.

[0015] 2. Provide a simple locking mechanism: The design of the screw and the slotted hole is not only simple and easy to implement, but also can effectively fix the positions of various components, avoiding displacement during the dispensing process, thus ensuring the consistency of the dispensing quality.

[0016] 3. Reduce costs: Only set the second chute on one side seat, reducing the processing cost and material cost. Fixing one side seat can reduce the complexity of the overall structure, simplify the structure, and facilitate maintenance and inspection.

[0017] 4. Increase the structural strength: The reinforcing rib can improve the overall rigidity of the side seat, reduce the deformation caused by external forces during use, and higher structural strength means longer service life and reduced maintenance and replacement frequency.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Referring to Figure 1 and Figure 2 , the present utility model provides a dispensing device for a circuit board.

[0026] In some embodiments, the dispensing device for a circuit board includes a base 1, a dispensing valve (not shown in the figure), and two relatively arranged side seats 2 on the base 1. It further includes a valve seat 3 and a mounting base 4 provided on the side seat 2. The dispensing valve is provided on the valve seat 3, the valve seat 3 is provided on the mounting base 4. A first slide rail 21 is provided on the side seat 2, and a first chute 41 is correspondingly provided on the mounting base 4. The mounting base 4 can slide vertically along the first slide rail 21. At least one end of the side seat 2 close to the base 1 is provided with a second chute 22, and a second slide rail 11 is correspondingly provided on the base 1. At least one side seat 2 can slide along the second slide rail 11 in a direction perpendicular to the sliding direction of the mounting base 4. A third chute 31 is provided on the valve seat 3, and a third slide rail 42 is correspondingly provided on the mounting base 4. The valve seat 3 can slide along the third slide rail 42 in a direction perpendicular to both the sliding direction of the side seat 2 and the sliding direction of the mounting base 4. It further includes a locking mechanism for locking the valve seat 3 and the mounting base 4, the mounting base 4 and the side seat 2, and the side seat 2 and the base 1 respectively.

[0027] Those skilled in the art should clearly understand that the dispensing valve is installed on the valve seat 3 according to the actual situation and performs the dispensing function. Although it is not shown in the figure, it should also be clear.

[0028] For the design of the locking mechanism, it is preferably to use a combination of screws, a slotted hole 5 and a screw hole 6 to achieve the locking purpose. In addition, a quick-release clamp can also be selected to lock the sliding parts. A positioning pin can also be added to provide additional protection for the sliding parts after locking to ensure that they will not move accidentally; or a magnetic locking part can be selected; or an elastic buckle can be used for locking; or other hydraulic or pneumatic locking systems. There is no special limitation here, as long as the valve seat 3 and the mounting base 4 can be locked, the mounting base 4 and the side seat 2 can be locked, and the side seat 2 and the base 1 can be locked.

[0029] At least one side seat 2 can slide along the second slide rail 11 in a direction perpendicular to the sliding direction of the mounting base 4, which means that both side seats 2 can slide along the second slide rail 11 in a direction perpendicular to the sliding direction of the mounting base 4, or one of the side seats 2 can slide along the second slide rail 11 in a direction perpendicular to the sliding direction of the mounting base 4.

[0030] The first slide rail 21, the second slide rail 11, and the third slide rail 42 are perpendicular to each other in pairs, enabling the entire dispensing device to adjust the three-dimensional coordinates of the dispensing valve.

[0031] In some embodiments, the locking mechanism includes screws (not shown in the figure) and elongated holes 5. The elongated holes 5 are respectively provided on the mounting base 4, the side seat 2, and the base 1. The length direction of the elongated holes 5 is respectively consistent with the sliding directions of the valve seat 3, the mounting base 4, and the side seat 2. The valve seat 3, the mounting base 4, and the side seat 2 are all provided with screw holes 6. The screws pass through the elongated holes 5 and are threadedly connected to the screw holes 6. When the screws respectively abut against the mounting base 4, the side seat 2, and the base 1, the valve seat 3 is fixed to the mounting base 4, the mounting base 4 is fixed to the side seat 2, and the side seat 2 is fixed to the base 1.

[0032] Those skilled in the art should clearly understand that the screws pass through the elongated holes 5, and the pre-tightening force generated by the cooperation of the screws and the screw holes 6 is used to fix the valve seat 3 to the mounting base 4, fix the mounting base 4 to the side seat 2, and fix the side seat 2 to the base 1. Although not shown in the figure, it should also be clear.

[0033] In some embodiments, only one of the two side seats 2 provided on the base 1 is provided with a second chute 22, and the other side seat 2 is fixedly provided on the base 1. The side seat 2 provided with the second chute 22 can slide along the second slide rail 11 towards or away from the other side seat 2. Only providing the second chute 22 on one side seat 2 reduces the processing cost and material cost. Fixing one side seat 2 can reduce the complexity of the overall structure, simplify the structure, and facilitate maintenance and inspection.

[0034] In some embodiments, the side seat 2 is provided with a reinforcing rib 7. The reinforcing rib 7 can improve the overall rigidity of the side seat 2, reduce deformation caused by external forces during use, and a higher structural strength means a longer service life, reducing the maintenance and replacement frequency.
