Description

Technical Field

[0001] This utility model relates to the field of PCB testing technology, and in particular to a vacuum fixture compatible with various PCBs. Background Technology

[0002] Existing PCB testing fixtures require manual operation, involving multiple face-to-face connections and multiple operating steps. These fixtures lack power and air supply, limiting their operational capabilities and restricting the working environment. Furthermore, the platform's vacuum suction cannot handle boards with too many connectors; a board with over 1000N of total connectors risks having its support column suspended in mid-air. Existing fixtures also have poor compatibility, being incompatible with boards exceeding 500×300mm in length and width, and with PCBs featuring densely packed or unevenly distributed connectors. Larger boards require larger frames and higher overall strength, and insufficient vacuum suction results in poor testing performance. Therefore, a vacuum fixture compatible with various PCB types needs to be designed. Utility Model Content

[0019] First, let me explain the design intent of this utility model. Existing fixtures lack power and air supply, making operation impossible and limiting the working environment. The platform's vacuum suction cannot suck up too many connectors on a single board. If the total number of connectors on a single board exceeds 1000N, there is a risk of the gantry column being suspended in mid-air. Furthermore, existing fixtures have poor compatibility, not being compatible with single boards with a length and width exceeding 500×300, nor with PCBs with densely packed or unevenly distributed connectors. The larger the single board, the larger the frame, and the higher the overall strength requirements. Insufficient vacuum suction results in poor testing performance. Therefore, this utility model designs a vacuum fixture that is compatible with various types of PCBs.

[0020] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1-5 As shown, a multi-PCB pressure vacuum fixture includes a test equipment platform 1, on which the pressure vacuum fixture is mounted. The pressure vacuum fixture will be described in detail below. The pressure vacuum fixture includes a platform docking component 2 mounted on the test equipment platform 1. The platform docking component 2 will be described in detail below. The platform docking component 2 includes a platform docking base 6 mounted on the test equipment platform 1. The bottom of the platform docking base 6 is provided with several docking interfaces 7.

[0021] In order to control the lifting and lowering of the carrier plate vacuum pressure floating assembly 3, two first control cylinders 8 are provided in the platform docking base 6, and the output end of the first control cylinder 8 is connected to the carrier plate vacuum pressure floating assembly 3.

[0022] A carrier board vacuum pressure floating assembly 3 is provided in the platform docking assembly 2. The carrier board vacuum pressure floating assembly 3 will be described in detail below. The carrier board vacuum pressure floating assembly 3 includes a floating carrier board 9 disposed on the platform docking assembly 2. Various PCB materials can be placed on the upper surface of the floating carrier board 9.

[0023] To facilitate the opening and closing of the upper finger plate vacuum chamber assembly 5, two second control cylinders 10 are provided on the floating carrier plate 9, and the output end of the second control cylinder 10 is connected to the upper finger plate vacuum chamber assembly 5.

[0024] The upper touch finger plate vacuum cavity assembly 5 is provided on the carrier plate vacuum pressure floating assembly 3 and connected by the connecting assembly 4. The connecting assembly 4 will be described in detail below. The connecting assembly 4 includes a connecting hinge 11 provided on the carrier plate vacuum pressure floating assembly 3, and the upper touch finger plate vacuum cavity assembly 5 is connected to the connecting hinge 11.

[0025] The upper finger plate vacuum chamber assembly 5 will be described in detail below.

Power and ventilation are achieved through this part. By pressing the "rise to position" button 16, the second control cylinder 10 is controlled to open the upper touch finger plate vacuum chamber assembly 5, placing the PCB on the floating carrier plate 9 and fixing it. By pressing the "press down to position" button 17, the second control cylinder 10 is controlled to close the upper touch finger plate vacuum chamber assembly 5, which is connected to the floating carrier plate 9. The vacuum chamber between the test chambers is used to achieve vacuum testing and docking. After passing the test, press the pass button 14; if the test fails, press the failure button 15. This PCB vacuum fixture has a clever structural design and strong practicality. It can be compatible with various similar PCB board tests.
