Problems solved by technology

In order to realize the function of the whole line, it is necessary to configure 2 to 3 manipulators, which greatly increases the equipment cost
[0005] 2. Poor stability
The stability of the whole line depends on the stability of the core manipulator, once the manipulator fails, all test stations will not work
[0006] 3. There will be capacity bottlenecks
For a manipulator with a radius of 1.5m, a maximum of 8 PCBA test fixtures for mobile phones can be placed, and a maximum of 6 PCBA test fixtures for routers can be placed, so the maximum production capacity is determined and cannot be increased by adding test fixtures.

Embodiment 1

[0043] Such as figure 1 and image 3 As shown, this embodiment discloses a circuit board transfer system comprising: a frame 11, a carrier 1, a lifting device and a translation device. It is used to transfer the circuit board 6 between the first station A and the second station B, wherein the position of the first station A is lower than the second station B, and the first station A and the second station The projections of bit B on the horizontal plane do not coincide.

[0044] Both the lifting device and the translation device are arranged on the frame 11; the circuit board 6 is placed on the carrier 1, and the lifting device and the translation device function with the carrier 1 to complete the transfer of the circuit board 6; the translation device includes a translation drive mechanism and a translation plate 5, the translation drive mechanism drives the translation plate 5 to move in the horizontal direction to transfer the carrier 1, one end of the stroke of the trans...

Embodiment 2

[0048] On the basis of Example 1, as figure 1 , figure 2 and image 3 As shown, the carrier 1 is provided with a first positioning hole 3 corresponding to the jacking column 8. The jacking column 8 includes a small diameter part and a large diameter part from top to bottom, and the diameter of the small diameter part is smaller than the first positioning hole 3. The diameter of the large diameter portion is larger than the first positioning hole 3 . Exemplary Figure 1 and image 3 As shown, the large-diameter portion is cylindrical, and the small-diameter portion is conical or truncated-conical, so that the first positioning hole 3 of the carrier 1 can be clamped at the junction of the large-diameter portion and the small-diameter portion. At least two translation positioning posts 10 are provided on the translation plate 5 , and second positioning holes 4 corresponding to the positioning posts of the translation plate 5 are provided on the carrier 1 . Exemplarily, the ca...

Embodiment 3

[0050] On the basis of the devices of the foregoing two embodiments. This example discloses two methods of transferring the circuit board 6, using the aforementioned circuit board transfer system to transfer the circuit board 6, one of which is the method of transferring the carrier 1 from the first station A to the second station B , the second is the method of transferring the carrier 1 from the second station B to the second station A.

[0051] Transferring the carrier 1 from the first station A to the second station B includes the following steps:

[0052] S100, the carrier 1 is moved to the first station A, and the lifting drive mechanism drives the lifting plate 9 to rise until the lifting column 8 lifts the carrier 1 to the top of the translation plate 5;

[0053] S200, the translation drive mechanism drives the translation plate 5 to move directly above the first station A, and the lift drive mechanism drives the lift plate 9 to descend until the carrier 1 is placed o...

Abstract

The invention discloses a circuit board transfer system and method. The circuit board transfer system and method enable a circuit board to transfer between a first working station and a second working station. The circuit board transfer system comprises a frame, a carrying tool, an elevating device and a translation device; the circuit board is placed on the carrying tool; the elevating device and the translation device are arranged on the frame; the translation device comprises a translation driving mechanism and a translation plate; the translation driving mechanism drives the translation plate to move horizontally in order to transfer the carrying tool; one end of a stroke of the translation plate is arranged right above the first working station and the other end of the stroke of the translation plate is in proximity to the second working station; the elevating device comprises an elevating driving mechanism, an elevating plate and at least three push-up columns; the elevating driving mechanism drives the elevating plate to vertically elevate; the lowest end of the stroke of the elevating plate is arranged right under the first working station; the push-up columns are vertically arranged right above the elevating plate and the push-up columns are arranged outside the stroke area of the translation plate to push up or put down the carrying tool. The circuit board transfer system and method are high in stability and low in cost.

Description

technical field [0001] The invention relates to the technical field of circuit board testing, in particular to a circuit board transfer system and method. Background technique [0002] In the electronics industry, PCBA testing is generally divided into different testing stations according to the functions of the motherboard. The difficulty of PCBA automatic testing is mainly that the positioning accuracy of the motherboard is high, and the automatic testing efficiency is high. For the PCBA automatic test line, in order to enhance the flexibility of the automatic test line, the test lines can be arranged in series in a way of sharing tracks. The pipeline test method can be further divided into on-track test and off-track test. The equipment structure of the on-orbit test is simple, but the abnormality of each station will block the entire track. At the same time, the test time of stations with different functions is different, which will also cause a certain degree of track...
