[0032] In working condition, rotating the rotating rod 56 clockwise or counterclockwise, the rotating rod 56 drives the gear 55 to rotate, and the rack 54 drives the lifting plate 52 to elevate along vertical direction under the meshing connection with the gear 55.

[0033] This structure is inlaid in the inside of fixed end 1, and the lifting plate 52 moves up and down by rotating the first rotating handle 57, to realize the distance in vertical direction and the throughput of process edge, so that the height of support bar 2 in vertical direction can be adjusted, and then the depth of clamping groove is adjusted to match the PCBA spliced board of different width.

[0036] The PCBA panel has a main body and a process edge. The process edge of the PCBA panel is placed in the clamping groove between the fixed end 1 and the moving end 3. The vertical position of the PCBA panel is adjusted by the vertical lifting component 5. The PCBA panel is clamped and fixed by the manual rotating screw transmission mechanism. The main body of the PCBA panel is flipped over to separate it from the process edge.

[0037] To limit the movement trajectory of the mobile device 3, a trajectory-limiting mechanism is also included, comprising a base arranged horizontally, a fixed end 1 fixedly disposed on one side of the top surface of the base, a corresponding slide rail or groove provided on the base along the movement trajectory of the mobile device 3, and a slider provided at a position corresponding to the mobile device 3 and the base, with the slider matching the slide rail or groove. This configuration limits the movement trajectory of the mobile device 3, making it more stable.

[0038] Working Principle: Based on a lead screw drive mechanism, the main lead screw 4 is installed on the fixed end 1 of the tooling separation mechanism via bearing 8. The other end of the main lead screw 4 is connected to the moving end 3 of the tooling separation mechanism. This establishes a lead screw drive mechanism that converts the angular displacement of the main lead screw 4 into the linear displacement of the tooling separation mechanism, ultimately fixing the entire process edge of the PCBA. This tooling can precisely adjust the linear displacement of the moving end of the separation mechanism according to the actual thickness of the PCBA, achieving accurate horizontal positioning. In the vertical direction of the working area of ​​the separation mechanism, the bottom support bar 2 is moved up and down via the vertical lifting component 5 to match the vertical depth of the tooling with the width of the pre-separated process edge of the PCBA, thereby minimizing the impact of mechanical stress on the solder joints of the surrounding components during separation. Both mechanisms employ electronic locking components to ensure the uniqueness of the horizontal and vertical displacements of the separation mechanism during use.

[0039] When the process edge of the PCBA is fully inside the working area of ​​its matching separation fixture, the board is manually flipped horizontally along the V-groove. The process edge will then be separated from the PCBA panel simultaneously. This fixture is modularly designed and can be freely combined according to the actual width of the panel to increase or decrease the width of the fixture, thereby achieving the versatility of the fixture.

[0040] The vertical direction bottom support strip 2 is adjusted by manually rotating the first rotating handle 57 of the vertical direction lifting assembly 5 to abut against the lower edge of the process edge and the double-sided V-groove center line is slightly higher than the separation mechanism by 0.5mm, the second rotating handle 7 is adjusted to move the distance between the moving end and the fixed end of the separation mechanism to be greater than the thickness of the process edge of the PCBA by 0.3-0.5mm, and the electronic locking member 6 is used to lock the adjustment position to ensure that the horizontal distance of the working area of the separation mechanism remains unchanged. After the above operation, the process edge of the double-sided V-groove panel PCBA to be separated is placed in the working area of the separation mechanism, and the panel is manually flipped in the horizontal direction of the V-groove, and the process edge is separated from the PCBA at one time. If the width of the process edge of the PCBA to be separated exceeds the maximum width of the tooling of 80mm, the tooling can be modularly combined according to the actual width of the panel to realize flexible increase of the width of the tooling, so as to realize the universality of the tooling.

[0041] The tooling is made of stainless steel material, and can allow the thickness of the process edge to be 0.8-10mm, the width to be 3.0-30mm, and the maximum allowed process edge length of the single-module separation mechanism to be 80mm (the allowed process edge length can be increased to 400mm by modular combination), which can cover most of the double-sided V-groove panel PCBA process edge separation requirements in the field of electronic surface assembly.
