Description

Technical Field

[0001] This application relates to the technical field of programming equipment, and in particular to an automatic PCBA programming device. Background Technology

[0002] PCBA automatic programming equipment, as an important component of the electronics manufacturing industry, is widely used in all stages of electronic product production, promoting efficient manufacturing of electronic devices and improving production efficiency and product quality. With the increasing demand for electronic products, efficient and accurate PCBA automatic programming equipment has become one of the key factors in improving the automation level of production lines, playing a crucial role in improving the reliability of electronic products and reducing costs.

[0003] Utility model patent publication number CN219778208U discloses an automated chip programming device, including a PCB board for programming. The PCB board includes a body and at least two chips electrically connected to the body. It includes: a first programming component and a second programming component arranged side-by-side along a first direction, and a base plate disposed outside the feeding ends of the first and second programming components. A carrier plate movable along the first direction is movably mounted on the upper surface of the base plate extending along the first direction. Two support side plates extending perpendicular to the first direction are spaced apart on the carrier plate. A motor is mounted on the surface of each support side plate opposite to the other support side plate. The output shaft of the motor passes through the support side plate and is mounted with a drive wheel. This utility model achieves automatic feeding of the PCB board via a conveyor belt and effectively avoids material retention during programming operations through the movement of the carrier plate. However, the automatic feeding equipment faces the problem of accurate feeding position. Automated programming equipment lacking positioning devices is prone to processing point deviations, resulting in low processing efficiency. Summary of the Invention

[0004] The purpose of this application is to provide an automatic PCBA programming device to solve the problem of inaccurate loading of materials into the automatic programming device.

[0005] The PCBA automatic programming device provided in this application adopts the following technical solution:

[0006] An automatic PCBA programming device includes:

[0007] The conveying assembly includes a conveyor frame and a conveyor belt, which rotates cyclically on the conveyor frame to transport PCBA boards.

[0008] The positioning component includes an abutment and a pressing component. The abutment is connected to a first driving component, which controls the abutment to move up and down. When the PCBA board is transported to the processing point, the abutment moves to the side of the conveyor belt to restrict the movement of the PCBA board. The pressing component is located on the upper side of the conveyor belt at the processing point to press the PCBA board onto the surface of the conveyor belt.

[0009] The programming component includes a moving frame and a programming device. The moving frame is mounted above the conveyor frame, and the programming device is connected to the moving frame. The moving frame drives the programming device to move.

[0010] By adopting the above technical solution, the abutment moves to the side of the conveyor belt when the PCBA board needs to be positioned, thereby accurately restricting the movement of the PCBA board. A pressing component is located on the upper side of the conveyor belt, clamping the PCBA board between the conveyor belt and the pressing component. This prevents the PCBA board from bouncing or shifting position after being obstructed by the abutment, ensuring positioning stability. After the PCBA board is processed, the abutment is lifted away from the side of the conveyor belt by the first driving component, allowing the PCBA board to continue moving outwards.

[0011] Optionally, the conveyor frame includes a fixed plate, a moving plate, and a translation frame. The fixed plate and the moving plate are parallel to each other and are both equipped with a conveyor belt and connected to the translation frame. The moving plate can move parallel to the top plate under the drive of the translation frame.

[0012] By adopting the above technical solution, the moving board moves parallel to the top plate through the translation frame, thereby changing the distance between the two conveyor belts, enabling the transport components to be used for the programming of PCBAs of different sizes, and improving the applicability of the programming equipment.

[0013] Optionally, the pressing component is connected to a second driving component, which is located on a conveyor frame and can push the pressing component to move up and down.

[0014] By adopting the above technical solution, the second driving component is used to adjust the distance between the pressing component and the conveyor belt, so that the pressing component can be applied to PCBA boards of different thicknesses and sizes, and the programming equipment has a wider range of applications.

[0015] Optionally, the movable frame includes a first slide rail, a second slide rail, and a third slide rail, which are connected sequentially and perpendicular to each other.

[0016] By adopting the above technical solution, the first slide rail, the second slide rail, and the third slide rail are connected in sequence and perpendicular to each other, so that the programming device can be moved within a space, thereby enabling programming processing on different positions on the PCBA board.

[0017] Optionally, the programming device includes a programming element and a labeling element.

[0018] By adopting the above technical solution, after the part is processed, it is necessary to check whether the processing was successful. The failed parts are marked with a label to facilitate identification after processing.

[0019] Optionally, the conveying assembly also includes multiple position sensors connected to the conveyor frame for detecting the position of the PCBA board.

[0020] By adopting the above technical solution, the position sensor is used to sense the movement position of the PCBA board. By sensing the movement position of the PCBA board, the movement of each component is controlled, so that the programming process can proceed normally.

[0021] Optionally, the conveying assembly also includes a lifting device installed between the stationary board and the moving board for lifting the PCBA board.

[0022] By adopting the above technical solution, the lifting device is used to lift the PCBA board, making the processing of the programming components more convenient and improving processing efficiency.

[0023] Optionally, a chassis assembly is also included, located outside the conveyor assembly, having loading and unloading ports corresponding to the conveyor belt.

[0024] By adopting the above technical solution, the chassis assembly can protect the programming process from external interference, and the loading and unloading ports allow PCBA boards to enter and exit the chassis assembly, enabling the programming equipment to load and unload normally.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The abutment moves to the side of the conveyor belt when the PCBA board needs to be positioned, thereby accurately restricting the movement of the PCBA board. A pressing part is provided on the upper side of the conveyor belt, so that the PCBA board is clamped between the conveyor belt and the pressing part. This prevents the PCBA board from bouncing or shifting position after being obstructed by the abutment part, thus ensuring the stability of the positioning.

[0027] 2. The moving plate moves parallel to the top plate via the translation frame, thereby changing the distance between the two conveyor belts, enabling the transport components to be used for programming PCBAs of different sizes, and improving the applicability of the programming equipment;

[0028] 3. The moving plate moves parallel to the top plate via the translation frame, thereby changing the distance between the two conveyor belts. This allows the transport components to be used for programming PCBAs of different sizes, improving the applicability of the programming equipment. Attached Figure Description

[0034] The present application will be further described in detail below with reference to the accompanying drawings.

[0035] An automatic PCBA programming device, as described in the following article Figure 1 and Figure 2 The system includes a conveying assembly 1, a positioning assembly 2, a programming assembly 3, and a chassis assembly 4. The conveying assembly 1 includes a conveyor frame 11 and a conveyor belt 12. The conveyor belt 12 rotates cyclically on the conveyor frame 11 to transport PCBA boards. The position on the PCBA board that is processed on the conveying assembly 1 is the processing position. The positioning assembly 2 is located around the processing position on the conveying assembly 1, and the programming assembly 3 is also installed above the processing position. The chassis assembly 4 is the mounting structure for the programming equipment. The conveying assembly 1, positioning assembly 2, and programming assembly 3 are all installed inside the chassis assembly 4. The chassis assembly 4 protects the programming process from external interference. The chassis assembly 4 has loading and unloading ports 41, which correspond to the conveyor belt 12, allowing PCBA boards to enter and exit the chassis assembly 4, enabling the programming equipment to load and unload normally.

[0036] Reference Figure 3The conveyor frame 11 includes a fixed plate 13, a movable plate 14, and a translation frame 15. Conveyor belts 12 are mounted on opposite sides of the movable plate 14 and the fixed plate 13. The conveyor belts 12 provide support on both sides of the PCBA board, driving its movement. The movable plate 14 and the translation frame 15 are fixedly connected, while the fixed plate 13 is mounted on the translation frame 15 and can move parallel to the movable plate 14 on the translation frame 15, thereby changing the distance between the conveyor belts 12. A fixing device 18 is also provided on the movable frame 11 to fix the position of the movable plate 14 on the translation frame 15. The movable plate 14 allows the conveyor assembly 1 to transport PCBA boards of different sizes, improving the applicability of the automatic programming equipment.

[0037] Reference Figure 3 and Figure 4 The positioning component 2 includes an abutment 21, a pressing member 22, a first driving member 23, and a second driving member 24. There are two of each of the first driving member 23 and the second driving member 24; one first driving member 23 and one second driving member 24 are connected to the sidewalls of both the fixed plate 13 and the moving plate 14. The abutment 21 is connected to the first driving member 23, which controls its vertical movement. The pressing member 22 is connected to the second driving member 24, which controls its vertical movement. When the PCBA board is transported to the processing point, the abutment 21 descends to the side of the conveyor belt 12, thereby preventing the PCBA board from moving forward. The pressing component 22 is located on the upper side of the conveyor belt 12 at the processing point. Before the PCBA board is transported to the processing point, it passes under the pressing component 22, so that the upper and lower sides of the PCBA board are restricted by the conveyor belt 12 and the pressing component 22, and the left and right sides are restricted by the moving plate 14 and the fixed plate 13. After being blocked by the abutting component 21, it can maintain accurate position, which is conducive to the precise performance of the burning process.

[0038] Reference Figure 2 The programming assembly 3 includes a movable frame 31 and a programming device 32. The movable frame 31 is located above the conveyor frame 11, and the programming device 32 is connected to the movable frame 31. The movable frame 31 drives the programming device 32 to move, thereby improving the positioning accuracy and programming reliability of the PCBA board. The movable frame 31 includes a first slide rail 33, a second slide rail 34, and a third slide rail 35. The programming device 32 includes a programming component 36 and a labeling component 37. The first slide rail 33 is located on both sides of the conveyor frame 11 and is parallel to the transport direction of the conveyor belt 12. The second slide rail 34 spans above the conveyor belt 12 and can move along the direction of the first slide rail 33. There are two third slide rails 35, which are respectively connected to the programming component 36 and the labeling component 37. The third slide rail 35 moves on the second slide rail 34 and can control the up and down movement of the programming component 36 and the labeling component 37.

[0039] Reference Figure 3 and Figure 4 The fixed plate 13 is also connected to the movable plate 14, and a lifting device 17 is provided between them. The lifting device 17 can raise the position of the PCBA board at the processing point. Since the pressing member 22 can be lifted upward, the PCBA board can be raised a certain distance by raising the pressing member 22 to facilitate the burning process of the programming component 3. The conveyor frame 11 is also equipped with multiple position sensors 16. The position sensors 16 are usually located below the area through which the PCBA board passes. By directly sensing the position of the PCBA board in the conveyor component 1, the corresponding equipment is controlled to move and operate.

[0040] The implementation principle of this application embodiment is as follows: The conveyor belt 12 transports the PCBA board from the conveyor frame 11 to the processing position. When entering the processing position, the surface of the PCBA board is restricted by the pressing member 22 and can only move along the direction of the conveyor belt 12. When the PCBA board is transported to contact the abutment member 21, the PCBA board can no longer move along the conveyor belt 12 and accurately stops at the processing position. At this time, the conveyor belt 12 stops, and the programming device 32, driven by the moving frame 31, performs programming processing on the PCBA board located at the processing position. After the programming processing is completed, the abutment member 21 is lifted under the action of the first driving member 23, so that the conveyor belt 12 can pass under the abutment member 21 and move away from the programming device.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
