Description

Technical Field

[0001] This utility model relates to the field of printed circuit board production equipment, and in particular to a printed circuit board mounting device. Background Technology

[0002] In the automatic placement process of PCB boards, traditional pick-and-place machines typically use feeders to supply surface mount components one by one, which has the following shortcomings: For multi-variety, small-batch production scenarios, frequent feeder changes lead to long changeover times (usually 10-30 minutes); small components (such as 01005 resistors and miniature capacitors) are prone to misalignment or leakage during feeding, reducing placement efficiency and failing to guarantee the placement quality of the circuit board. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a printed circuit board placement device. By pre-installing all the components to be placed on the carrier board, the problem of frequent feeder changes in traditional placement machines is avoided. The line changeover time can be shortened from 10-30 minutes to 1-2 minutes, which significantly improves the efficiency of multi-variety small-batch production and ensures the placement quality of the circuit board.

[0004] The objective of this utility model is achieved through the following technical solution:

[0019] Figures 1-4 The present invention relates to a printed circuit board mounting device, comprising a worktable 10, a Y-axis moving assembly 20, a carrier assembly 30, a mounting assembly 40, and an electrical control box 60.

[0020] In this embodiment:

[0021] The worktable 10 includes a base plate 11 and a guide rail 12, with the guide rail 12 mounted on the base plate 11.

[0022] The Y-axis moving assembly 20 includes a slider 21, a slider connecting plate 22, a cylinder connecting plate 23, a Y-axis cylinder 24, and a mounting plate 25. The slider 21 is slidably mounted on the guide rail 12. The slider connecting plate 22 is fixedly connected to the slider 21. The mounting plate 25 is mounted on the slider connecting plate 22. The Y-axis cylinder 24 is located on one side of the guide rail 12. The cylinder connecting plate 23 is located at the output end of the Y-axis cylinder 24 and is connected to the slider connecting plate 22. The mounting plate 25 is mounted on the worktable 10 for placing the PCB board.

[0023] The carrier assembly 30 includes a drive unit 31 and a carrier plate 32. The surface of the carrier plate 32 is provided with multiple mounting holes for mounting the parts to be mounted 70. The shape and size of the mounting holes match the parts to be mounted 70 to ensure that the parts are fixed in position within the mounting holes.

[0024] The electrical control box 60 controls the drive unit 31 to move the carrier board 32 directly above the PCB board, or controls the mounting plate 25 to move the PCB board directly below the carrier board 32. In this embodiment, the electrical control box 60 controls the Y-axis cylinder 24 to move the mounting plate 25 and the PCB board directly below the carrier board 32, and the drive unit 31 places the carrier board 32 onto the PCB board.

[0025] The surface mount assembly 40 includes a Z-axis cylinder 41 and a pressure plate 42. The pressure plate 42 is located directly above the carrier board 32. The electrical control box 60 controls the Z-axis cylinder 41 to drive the pressure plate 42 to move downward, so as to push out the components in the mounting holes of the carrier board 32 and mount them onto the PCB pads.

[0026] The carrier board 32 is also provided with positioning marks. The vision camera 50 is set on the mounting plate 25 to capture the positioning marks on the carrier board 32 and the Mark points on the PCB board, calculate the positional deviation between the carrier board 32 and the PCB board, and transmit the deviation data to the electrical control box 60.

[0027] The electrical control box 60 is electrically connected to the surface mount assembly 40 and the vision camera 50. It is used to receive the deviation data of the vision camera 50. The electrical control box 60 controls the extension of the piston rod of the Z-axis cylinder 41 and pushes the pressure plate 42 to push the component out of the mounting hole and mount it onto the PCB pad.

[0028] The working process for this application is as follows:

[0029] First, install the component 70 to be mounted into the mounting hole of the carrier board 32 according to the preset position, then place the carrier board 32 on the worktable 10 and place the PCB board on the mounting plate 25;

[0030] Next, the vision camera 50 captures the positioning marks on the carrier board 32 and the Mark points on the PCB board, calculates the positional deviation between the carrier board 32 and the PCB board, and transmits the deviation data to the control box 60. The control box 60 controls the Y-axis cylinder 24 to move along the length of the guide rail 12 according to the deviation data, moving the mounting plate 25 and the PCB board directly below the carrier board 32. The drive unit 31 places the carrier board 32 onto the PCB board, aligning the components in the mounting holes with the pads on the PCB board.

[0031] The electrical control box 60 controls the Y-axis cylinder 24 to move in the opposite direction, moving the mounting plate 25, PCB board, and carrier board 32 to the placement station. Then, it controls the piston rod of the Z-axis cylinder 41 to extend and push the pressure plate 42 to push the components out of the mounting holes and place them onto the PCB pads.

[0032] After mounting is complete, the piston rod of Z-axis cylinder 41 retracts, removing the carrier board 32 and the mounted PCB board. The above process is repeated until all components are mounted.

[0033] In this application, by pre-installing all components to be mounted on the carrier board 32, the problem of frequent feeder changes in traditional pick-and-place machines is avoided. The changeover time can be shortened from 10-30 minutes to 1-2 minutes, significantly improving the efficiency of multi-variety, small-batch production and ensuring the quality of PCB mounting. The mounting holes on the carrier board 32 match the shape and size of the components, ensuring that the components are fixed in position on the carrier board 32, avoiding the problem of small components shifting or leaking during the feeding process, and improving the stability and reliability of mounting. This device has a simple structure, is easy to implement, can be modified based on existing automatic PCB pick-and-place machines, has low cost, and has strong practicality and promotional value.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
