Description

Technical Field

[0001] The utility model relates to the technical field of testing machinery, in particular to an adsorption platform and a detection device. Background Art

[0002] The flying probe tester is mainly used to test circuit boards, which are divided into two categories. One is to test PCBs, and the other is to test PCBAs. Among them, the flying probe tester for testing PCBs is an instrument for testing PCB (printed circuit board) with high component layout density, many layers, large wiring density, and small measuring point distance, and mainly tests the insulation and conduction values of the circuit board.

[0003] In the prior art, one or more loading platforms capable of carrying PCBs are arranged on the flying probe tester. When the PCB needs to be tested, the PCB needs to be placed on the loading platform first, so that the detection needles on the flying probe tester can contact the PCB under the drive of the positioning mechanism, and then the detection needles can detect the PCB. In addition, in order to avoid the situation that when the detection needle contacts the PCB, the detected part drives the PCB to move on the loading platform, resulting in inaccurate detection results, some flying probe testers replace the loading platform with an adsorption platform, so that when the PCB is placed on the adsorption platform, the adsorption platform can adsorb the PCB, thus avoiding the PCB from moving on the adsorption platform when the detection needle contacts the PCB.

[0004] However, the adsorption platform on the existing flying probe tester only adsorbs the PCB by an air pump, and its adsorption effect is not good. There is still a situation where the detection needle drives the PCB to move (and the PCB has different steel thicknesses and stress concentrations, corresponding to different board warps and cannot be flattened), resulting in low installation stability of the PCB and low detection accuracy of the flying probe tester. Summary of the Utility Model

[0005] Therefore, the technical problem to be solved by the present utility model is to overcome the defects that the existing flexible circuit board mounting relies on manual operation, resulting in low mounting efficiency and inability to meet production requirements.

The first fitting part is arranged between any two adjacent insulating parts, and the first fitting part is adapted to be connected to an external power supply, so as to form a first capacitor between the first fitting part and the PCB board after the PCB board is powered on.

[0012] Optionally, for the above adsorption platform, the bearing assembly further includes a second fitting part provided with the air permeation channel. The second fitting part is arranged between another two adjacent insulating parts, and the second fitting part is adapted to be connected to an external power supply, so as to form a second capacitor between the second fitting part and the PCB board after the PCB board is powered on.

[0013] Optionally, for the above adsorption platform, the first fitting part is made of iron, the second fitting part is made of copper, and the first fitting part, the second fitting part and all the insulating parts have the same size.

[0017] The support assembly includes a connecting member and a support member that are connected to each other. The connecting member is adapted to be connected to the body, and the support member is adapted to be connected to the detection device.

[0018] Optionally, for the above-mentioned adsorption platform, the support assembly further includes an adjusting member and a locking member connected to the support member. The adjusting member is provided with an adjusting portion, and the locking member is adapted to pass through the adjusting portion and be connected to the connecting member to connect the adjusting member and the connecting member.

[0020] The technical solution provided by the present utility model has the following advantages:

[0021] 1. The adsorption platform provided by the present utility model includes a body and a bearing assembly. The body has an adsorption cavity with an open side and a plurality of communication parts communicated with the adsorption cavity. The communication parts are adapted to be communicated with an external air extraction device; the bearing assembly covers and is arranged on the body in an open manner to close the adsorption cavity. The bearing assembly is adapted to bear a PCB board, and a plurality of air permeation channels are arranged at intervals on the bearing assembly to enable the adsorption cavity to communicate with the outside through the air permeation channels; under the action of the external air extraction device, the gas in the adsorption cavity is adapted to flow out through the communication parts into the external air extraction device, and the outside air is adapted to flow into the adsorption cavity through the air permeation channels.

The bearing component specifically covers the opening on the body to seal the adsorption cavity. A plurality of air permeable channels are arranged at intervals on the bearing component to communicate the outside with the adsorption cavity. When the external air extraction device extracts the air in the adsorption cavity, the outside air can flow into the adsorption cavity through all the air permeable channels. At the same time, it should be noted that under the action of the external air extraction device, the rate at which the gas in the adsorption cavity flows out through the communication part is greater than the rate at which the outside air flows into the adsorption cavity through the air permeable channels, so that the air pressure in the adsorption cavity is in a negative pressure state. In addition, the bearing component can bear the PCB board. When the PCB board is placed on the bearing component, since the air pressure in the adsorption cavity is in a negative pressure state, the PCB board will be adsorbed on the bearing component by negative pressure, so as to fix the PCB board on the body. Furthermore, when detecting the PCB board, the situation that the position of the PCB board changes and the detection result is inaccurate can be avoided, which is beneficial to improving the detection stability of the PCB board.

[0036] Embodiment 1

[0037] This embodiment provides an adsorption platform, such as Figures 1 to 4As shown in the figure, it includes a main body 1 and a bearing component 2. The main body 1 has an adsorption cavity 11 with an open side and several communication parts 12 communicated with the adsorption cavity 11. The communication parts 12 are adapted to be communicated with an external air extraction device; the bearing component 2 is covered and arranged on the main body 1 in an opening manner to close the adsorption cavity 11. The bearing component 2 is adapted to bear a PCB board, and several air permeable channels are arranged at intervals on the bearing component 2, so that the adsorption cavity 11 is communicated with the outside through the air permeable channels; under the action of the external air extraction device, the gas in the adsorption cavity 11 is adapted to flow out through the communication part 12 into the external air extraction device, and the outside air is adapted to flow into the adsorption cavity 11 through the air permeable channels. The outflow rate of the gas in the adsorption cavity 11 is greater than the inflow rate of the outside air, so that the adsorption cavity 11 is in a negative pressure state, and the PCB board is adsorbed on the bearing component 2.

[0038] For the adsorption platform with the above structure, through the bearing component 2 arranged on the main body 1, wherein, the main body 1 has an adsorption cavity 11 with an open side and several communication parts 12 communicated with the adsorption cavity 11. The communication part 12 is a communication hole for communicating the external air extraction device and the adsorption cavity 11 in this embodiment. The communication part 12 can be communicated with the external air extraction device, so that the air in the adsorption cavity 11 can be pumped out into the external air extraction device under the action of the external air extraction device. The bearing component 2 is specifically covered and arranged on the main body 1 in an opening manner, so as to close the adsorption cavity 11, and several air permeable channels are arranged at intervals on the bearing component 2 to communicate the outside with the adsorption cavity 11 through the air permeable channels. When the external air extraction device extracts the air in the adsorption cavity 11, the outside air can flow into the adsorption cavity 11 through all the air permeable channels.

[0039] At the same time, it should be noted that under the action of the external air extraction device, the outflow rate of the gas in the adsorption cavity 11 through the communication part 12 is greater than the inflow rate of the outside air through the air permeable channels into the adsorption cavity 11, so that the air pressure in the adsorption cavity 11 is in a negative pressure state. In addition, the bearing component 2 can bear the PCB board. When the PCB board is placed on the bearing component 2, since the air pressure in the adsorption cavity 11 is in a negative pressure state, therefore, the PCB board will be adsorbed on the bearing component 2 by negative pressure, so as to fix the PCB board on the main body 1. Furthermore, when detecting the PCB board, the situation that the position of the PCB board changes and the detection result is inaccurate can be avoided, which is beneficial to improving the detection stability of the PCB board.

At the same time, all the insulating parts are provided with air-permeable channels, so that when the insulating parts cover the opening, the adsorption cavity 11 can communicate with the outside through the air-permeable channels. In addition, the PCB board can be placed on the insulating parts, so that there is no power connection between the PCB board and the body 1. Furthermore, when using the detection part to power on the PCB board for detection, the detection accuracy of the PCB board can be effectively improved, and the interference of the body 1 on the detection of the PCB board can be avoided.

[0042] The adsorption platform provided in this embodiment, as Figure 1 and Figure 2 shown, the bearing component 2 further includes a first fitting provided with an air-permeable channel. The first fitting is arranged between any two adjacent insulating parts, and the first fitting is suitable for connecting with an external power source to form a first capacitor between the first fitting and the PCB board after the PCB board is powered on.

[0043] The adsorption platform with the above structure, by setting the bearing component 2 to further include a first fitting, the first fitting is the first conductive film in this embodiment, the first fitting is arranged between two adjacent insulating parts, that is, there is insulation between the first fitting and the PCB board, and the first fitting is suitable for connecting with an external power source, so that there can be current on the first fitting. Furthermore, after the PCB board is powered on, a first capacitor can be formed between the first fitting and the PCB board, and after the detection part contacts the PCB board, the first capacitor between the PCB board and the first fitting can be detected, so that the staff can judge whether the PCB board meets the standard, that is, whether the PCB board is qualified according to the size of the first capacitor.

[0044] The adsorption platform provided in this embodiment, as Figure 1 and Figure 2 shown, the bearing component 2 further includes a second fitting provided with an air-permeable channel. The second fitting is arranged between another two adjacent insulating parts, and the second fitting is suitable for connecting with an external power source to form a second capacitor between the second fitting and the PCB board after the PCB board is powered on.

The second fitting is disposed between two adjacent insulating members, that is, the second fitting and the PCB are insulated from each other, and the second fitting is adapted to be connected to an external power source, so that a current can exist on the second fitting. Further, after the PCB is powered on, a second capacitor can be formed between the second fitting and the PCB. And after the detection member contacts the PCB, the second capacitor between the PCB and the second fitting can be detected, so that the staff can determine whether the PCB meets the standard, that is, whether the PCB is qualified according to the magnitude of the second capacitor.

[0046] In addition, in this embodiment, the detection of the PCB is mainly achieved by contacting the energized detection needle with the PCB placed on the body 1 to energize the PCB. At the same time, the first fitting and the second fitting are energized by an external power source, so that a capacitor is formed between the PCB and the first fitting or the second fitting. Further, the staff can determine whether the PCB is qualified according to the magnitude of the capacitor. Among them, the first fitting and the second fitting work independently to avoid interference.

[0047] The adsorption platform provided in this embodiment, as Figure 1 and Figure 2 shown, the material of the first fitting is iron, the material of the second fitting is copper, and the first fitting, the second fitting and all the insulating members have the same size.

Further, when the PCB is detected by using the detection member, two detection data can be obtained. And to ensure that the characteristics of the first fitting and the second fitting except the material are the same, the sizes of the first fitting and the second fitting are made exactly the same, thus ensuring the detection accuracy of the PCB, that is, it is beneficial to improve the detection accuracy of the PCB.
