Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to an SMT inkjet printing and feeding device. Background Technology

[0002] In the current PCB manufacturing process, it is necessary to perform inkjet printing on the PCB or to quickly and accurately mount SMD components onto the PCB. These tasks are usually completed by SMT pick-and-place machines. During the inkjet printing process, the PCB is placed under the inkjet gun by conveyor belt. The conveyor belt is made of flexible material, which causes the PCB to vibrate significantly during the conveying process. This causes the PCB to deviate from the preset position, resulting in inkjet printing position deviation and reducing the accuracy of inkjet printing. Utility Model Content

[0003] The purpose of this invention is to provide an SMT inkjet printing and feeding device that solves the problem of deviation from the expected position during the inkjet printing process in the prior art.

[0004] To achieve this objective, the present invention adopts the following technical solution: The present invention provides an SMT inkjet printing and feeding device, including a main platform, a feeding component installed on the main platform, the feeding component moving a PCB board to the upper side of the main platform, an adsorption component installed on the upper side of the main platform, the adsorption component placing the PCB board lifted by the feeding component onto a limiting component, the limiting component fixing the PCB board, the limiting component moving on the main platform, an inkjet printing component also installed on the main platform, the inkjet printing gun in the inkjet printing component facing the PCB board on the limiting component, the inkjet printing gun being able to print on the PCB board, a rising area formed inside the main platform, the feeding component installed in the rising area, the feeding component including a first tray and a first guide rail, the first guide rail being installed in the rising area perpendicular to the plane of the PCB board, the first guide rail being connected to the first tray via a linear motor.

[0005] Preferably, a first conveyor belt is installed at the bottom of the rising area, the first conveyor belt transports PCB boards, and a first through hole is opened on the first tray, through which the first conveyor belt can pass.

[0006] Preferably, a first U-shaped frame is installed on the main body platform, and the adsorption component is installed on the first U-shaped frame. The adsorption component includes a first telescopic cylinder and a suction cup. The first telescopic cylinder pushes the first telescopic rod to move. The end of the first telescopic rod has a fixing plate. A suction cup is installed on the side of the fixing plate near the feeding component. The suction cup is connected to an air pump and can adsorb the PCB board.

[0007] Preferably, a first linear bearing is installed on the first U-shaped frame, a first positioning rod is inserted into the first linear bearing, and the end of the first positioning rod is connected to the fixing plate.

[0008] Preferably, the first conveyor belt includes two sets, which are respectively disposed on both sides of the PCB board, and the first through hole corresponds to the first conveyor belt one by one.

[0009] Preferably, a bracket is installed at the bottom of the rising zone, a drive motor is installed on the bracket, a gear is installed at the front end of the drive motor, the gear meshes with the inner side of the first conveyor belt, and the first conveyor belt is wound around the roller.

[0010] Preferably, a transmission rod is installed between the two rollers, and the transmission rod drives the rollers to rotate.

[0011] Beneficial effects: The PCB board is conveyed to the rising area by the conveying device. The first tray in the feeding assembly moves upward and eventually reaches the designated position. The first tray slides along the first guide rail. Since the first tray and the first guide rail are rigid structures, the PCB board remains stable during the movement, and the offset of the PCB board is reduced. This reduces the need for subsequent correction of the PCB board offset, making the PCB board inkjet printing process more stable and accurate. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0019] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0022] In the current technology, the PCB board is placed on the conveyor belt during the spraying process. The conveyor belt is made of flexible material. During the spraying process, the machine will vibrate, and the conveyor belt will vibrate significantly. This will cause the inkjet gun to deviate after spraying on the PCB board, resulting in errors in the inkjet printing position.

[0023] To solve the above problems, such as Figures 1 to 5As shown, this utility model provides an SMT inkjet printing and feeding device, including a main platform 1, on which a feeding component 3 is installed. The feeding component 3 moves a PCB board 2 to the upper side of the main platform 1. An adsorption component 4 is installed on the upper side of the main platform 1. The adsorption component 4 places the PCB board 2 lifted by the feeding component 3 onto a limiting component 5. The limiting component 5 fixes the PCB board 2 and moves on the main platform 1. An inkjet printing component 6 is also installed on the main platform 1. The inkjet printing gun 61 in the inkjet printing component 6 faces the PCB board 2 on the limiting component 5, and the inkjet printing gun 61 can print on the PCB board 2.

[0024] The conveying component transfers the PCB board 2 onto the feeding component 3, which then transports the PCB board 2 to the adsorption component 4. The adsorption component 4 then transfers the PCB board 2 to the limiting component 5.

[0025] The main platform 1 has an ascending area, and a feeding component 3 is installed in the ascending area. The feeding component 3 includes a first tray 31 and a first guide rail 32. The first guide rail 32 is installed in the ascending area on a plane perpendicular to the PCB board 2. The first guide rail 32 is connected to the first tray 31 through a linear motor.

[0026] The first pallet 31 moves on the first guide rail 32, enabling it to accept PCB boards 2 transported from different heights. This allows for better coordination and adaptability with production lines using different conveying devices within the factory. Furthermore, since the first pallet 31 moves via a linear motor on the first guide rail 32, it is more stable than transporting directly via a flexible belt. This reduces the amplitude of PCB board swaying during transport, thereby reducing the offset of the PCB board 2 during movement. This allows the PCB board to get closer to the coding position, resulting in higher coding accuracy.

[0027] A first conveyor belt 33 is installed at the bottom of the rising area. The first conveyor belt 33 transports the PCB board 2. A first through hole is opened on the first tray 31, and the first conveyor belt 33 can pass through the first through hole.

[0028] Typically, before inkjet printing on PCB board 2, PCB boards 2 are stacked together. The stacked PCB boards 2 can be directly transferred to the first conveyor belt 33. At this time, the position of the first tray 31 is lower than that of the first conveyor belt 33. Through the linear motor on the first guide rail 32, the stacked PCB boards 2 on the first conveyor belt 33 can be lifted by the first tray 31, so that the PCB boards 2 are close to the adsorption component 4. The feeding component 3 can handle a large number of PCB boards 2, improving work efficiency.

[0029] A first U-shaped frame 7 is installed on the main platform 1, and an adsorption assembly 4 is installed on the first U-shaped frame 7. The adsorption assembly 4 includes a first telescopic cylinder 41 and a suction cup 43. The first telescopic cylinder 41 pushes the first telescopic rod to move. The end of the first telescopic rod has a fixed plate 42. The side of the fixed plate 42 near the feeding assembly 3 is equipped with a suction cup 43. The suction cup 43 is connected to an air pump and can adsorb PCB board 2. By controlling the movement of the first telescopic rod through the first telescopic cylinder 41, the height of the fixed plate 42 can be adjusted, thereby changing the height of the suction cup 43, which can adsorb PCB board 2 of different heights. When PCB board 2 is needed, the suction cup 43 on the fixed plate 42 can be turned into a negative pressure state, and the air pump can be started, so that the PCB board 2 can be adsorbed on the suction cup 43 and placed on the limiting assembly 5. After being placed on the limiting assembly 5, the suction cup 43 closes and returns to its initial state. The PCB board 2 can be transported by using the suction cup 43, which can reduce damage to the PCB board 2 during the transportation process.

[0030] A first linear bearing 44 is installed on the first U-shaped frame 7, and a first positioning rod 45 is inserted into the first linear bearing 44. The end of the first positioning rod 45 is connected to the fixed plate 42. By installing the first positioning rods 45 around the fixed plate 42, when the first telescopic rod pushes the fixed plate 42 to move, the first positioning rods 45 can make the fixed plate 42 more stable during the movement, and can move stably along the axis of the first positioning rod 45 and the first telescopic rod, reducing the amplitude of the swaying of the fixed plate 42, thereby making the suction cup 43 more stable in adhering to the PCB board 2.

[0031] The first conveyor belt 33 includes two sets, which are respectively disposed on both sides of the PCB board 2, and the first through hole corresponds one-to-one with the first conveyor belt 33. By setting two sets of first conveyor belts 33, the PCB board 2 can be supported from both sides, and after the first conveyor belt 33 receives the PCB board 2 to be sprayed from the outside, the PCB board can be placed stably under the vibration of the machine.

[0032] A bracket 8 is installed at the bottom of the rising zone, and a drive motor is mounted on the bracket 8. A gear is installed at the front end of the drive motor, and the gear meshes with the inner side of the first conveyor belt 33. The first conveyor belt 33 is wound around the roller 9. The first conveyor belt 33 is driven to rotate by the gear on the output end of the drive motor, which increases the friction between the first conveyor belt 33 and the gear, and can move more PCB boards 2. A transmission rod 10 is installed between the two rollers 9. The gear drives the roller 9 on one side to rotate, and the roller 9 transmits the rotation to the first conveyor belt 33 on the other side through the transmission rod 10, so that a single drive motor drives two sets of first conveyor belts 33 to rotate.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
