Problems solved by technology

In this process, because it takes a certain amount of time to move the clapper lever 81, it takes a lot of time to perform alignment, and one side of the board may touch the Y-direction limit plate 7, and in the process of moving the board, it will The board causes a certain amount of friction, which leads to a decrease in the yield of the board
In addition, because the two clapper levers 81 of the X-direction clapper structure 8 will directly hit the edge of the board during the clapper process, it will cause damage to the PCB board, and it is easy to cause chip shedding, causing defective
[0005] At present, when many manufacturers start to solve the efficiency and speed problems caused by the clapper, they mostly start from the structural movement stroke. The shorter the time between the start of the movement of the clapper lever and the completion of the alignment, the shorter the time consumed by the clapper. , the efficiency can be improved to a certain extent by compressing the duration. The main way to shorten the duration is to speed up the movement speed; but the improvement is very limited
On the one hand, it is because, no matter how fast the speed is, the mechanical stroke still exists, and the existence of the mechanical stroke makes it impossible to shorten the duration to a large extent; secondly, because the shortening of the duration will affect the stability of the equipment, the speed of the gear lever The faster, the greater the stability and risk of collision, and the greater the damage to the board
That is to say, in the prior art, when solving the speed and efficiency problems caused by clappers, it is necessary to sacrifice the stability of the equipment, and because of the need to worry about the stability of the equipment, the speed of the clapper lever cannot be greatly improved, so the efficiency The improvement is very limited

Embodiment 1

[0041] like image 3 and Figure 4As shown, this embodiment provides a visual aid alignment device for LDI automatic wiring, the device includes a delivery platform 1, an exposure platform 2 and a manipulator 3, and a tool for positioning the PCB board 4 on the delivery platform 1 The positioning system 5 has a Y-direction limit plate 7 on the conveying platform 1, the positioning system 5 is connected to the control module 6 for sending the positioning result to the control module 6, and the control module 6 is connected to the exposure platform 2 to make the exposure platform 2 according to the positioning As a result, it moves to the corresponding position to adapt to the current position of the PCB board 4 , and there is no need to make a decision on the PCB board 4 in the X direction. The positioning system 5 is a visual positioning system, and the visual positioning system includes a visual information acquisition module 51 and a visual information processing module 52 ...

Embodiment 2

[0052] The manipulator 3 in the first embodiment can adapt to any position of the PCB board, and after the PCB board 4 is transported to the end close to the exposure platform 2, the manipulator 3 is controlled to perform the grabbing action. This embodiment is similar to Embodiment 1, the difference is that the manipulator 3 of this embodiment cannot grab the PCB board 4 at any position, for example, if a manipulator 3 with a group or a small number of suction cups is used, it may be necessary to adjust the manipulator 3 Make position adjustments. like Figure 8 and Figure 9 As shown, the control module 6 receiving position information is connected to the manipulator 3 so that the manipulator 3 is adjusted to the target position suitable for the position of the PCB board 4 before grabbing the PCB board 4, that is, the controller 9 adjusts the manipulator according to the position information of the PCB board 4 3 After grabbing the PCB board 4.

Embodiment 3

[0054] like image 3 As shown, this embodiment is similar to Embodiment 1 or Embodiment 2, the difference is that the manipulator of this embodiment adopts a sufficient number of suction cups, and by controlling different suction cups, it can effectively grasp PCB boards at any different positions. In an example, the control module 6 is connected to the manipulator 3, and the control module 6 controls the corresponding sucker of the manipulator 3 to be effective according to the positioning result to realize the grasping of the PCB board at the current position. That is, the automatic controller 9 controls the manipulator 3 to grab the PCB board 4 and at the same time controls the corresponding sucker of the manipulator 3 to be effective according to the position information.

Abstract

The invention provides a visual auxiliary alignment device and method for LDI automatic connection. The visual auxiliary alignment device comprises a conveying platform, an exposure platform, a manipulator and a positioning system used for positioning a PCB on the conveying platform. The positioning system is connected to a control module and used for sending a positioning result to the control module. And the control module is connected to the exposure platform so as to enable the exposure platform to move to a corresponding position adaptive to the position of the PCB. According to the scheme, the traditional clapper positioning thinking is broken through, radio pulse signal transmission and data processing are used for replacing mechanical movement, the speed limit of the mechanical movement is broken through, the time required for clapper alignment can be greatly shortened, the clapper impacting process is omitted, the equipment stability can be improved, and the yield of PCBs is guaranteed to the maximum extent.

Description

technical field [0001] The invention belongs to the technical field of exposure connection, and in particular relates to a visual aid alignment device and a method for LDI automatic connection. Background technique [0002] Automation is the trend of production workshops. For example, LDI exposure is currently using automatic connection and loading and unloading. The main advantages of automation are that on the one hand, it saves manpower, and on the other hand, it also greatly improves the production capacity. [0003] But automation is not a once-and-for-all thing, and automation equipment needs to be improved again and again to continuously improve the performance, work efficiency, and production capacity of automation equipment. For LDI automatic wiring equipment, the stability and production capacity of the equipment will directly determine the benefit of the board factory. The higher the stability, the higher the production capacity, the higher the board yield of the...
