Description

Technical Field

[0001] The utility model relates to the technical field of board splitters, and more specifically to an LED board splitter with adjustable spacing. Background Art

[0002] LED board splitter adopts the latest pneumatic and electric lightweight design, and completes the micro-shear stress board cutting stroke in one go. It is suitable for cutting PCB circuit boards with V-grooves and MCPCB circuit boards (aluminum substrates). Board splitters are widely used in the electronic product manufacturing industry. Since the traditional manual board folding method will produce strong stress and have a serious impact on product quality, manual board folding has basically been replaced by machine board splitting.

[0003] Circuit boards are essential components in electronic products. During the production of electronic products, a board splitter is needed to split the circuit boards. The cutting distance between the cutter and the circuit board in the existing LED board splitter is mostly fixed in diameter, which is not easy to adjust and has a small application range. In addition, the cutting process is a one-time cut, so that the surface of the split circuit board may have burrs or warped edges. Therefore, this scheme proposes an LED board splitter with adjustable spacing. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0038] See also Figure 1-5 , a spacing adjustable LED panel splitter, comprising a workbench 1, a body 2 is mounted on the side of the workbench 1, a front end of the body 2 is fixedly connected with a docking seat 3, and the docking seat 3 is located on the upper side of the workbench 1, wherein;

[0039] The front end of the connecting seat 3 is provided with three evenly distributed slide grooves 31, a moving part 32 is movably installed between the inner walls of the slide grooves 31, an infrared distance sensor 33 is installed at the inner top of the slide groove 31, and the infrared distance sensor 33 is located on one side of the transmission shaft of the transmission part 34. The upper end of the connecting seat 3 is penetrated by the transmission part 34, and the transmission part 34 is movably connected with the moving part 32. The front end of the connecting seat 3 is fixedly connected with a connecting plate 35, and the front end of the connecting plate 35 is installed with a display panel 36, and the display panel 36 is wirelessly connected with the infrared distance sensor 33;

[0040] Three upper slices 4 are installed between the inner walls of the connecting plate 35, and the transmission shafts of the three upper slices 4 all pass through the moving part 32 to the rear side of the connecting seat 3, and the other ends of the transmission shafts of the upper slices 4 are installed with motors. A positioning part 5 is also provided at the upper end of the workbench 1, and the positioning part 5 is located on one side of the machine body 2.

[0041] More specifically, three evenly distributed lower cutting knives are installed on the upper end of the workbench 1 , and the three lower cutting knives are respectively located at the lower side of the upper slice 4 , wherein the minimum spacing between the two is 0.3 mm.

[0042] During the use of this solution, in order to make the existing LED board splitter more convenient and efficient in cutting the circuit board, and the cutting spacing can also be freely adjusted, in this embodiment, the personnel first put the circuit board to be cut against the surface of the positioning member 5, and align the V-shaped groove of the circuit board to be cut to the upper slice 4 under the adjustment of the positioning member 5, and then adjust each transmission member 34 respectively to adjust the spacing between each group of cutting blades. At the same time, during the spacing adjustment, the infrared distance sensor 33 measures the distance that the moving member 32 moves up and down to the upper slice 4 by generating infrared rays, and transmits the measured distance data to the display panel 36, so that the personnel can make precise adjustments to the spacing between the cutting blades during operation;

[0043] And in this scheme, its cutting piece is completed by 3 sets of blades, and the upper and lower pieces are a group, forming a cutting unit group, such as Figure 1 As shown, from left to right, there are three groups, A, B, and C. The travel spacing between the three groups of blades is different. During the cutting process, the A group of blades first cuts 40% of the V-groove part of the circuit board, and then the B blade rolls over the groove cut by the A blade again, and completes the cutting of 40% of the V-groove part again. Finally, the C group of blades cuts the last 20% and finishes it. Since the cutting amount each time is very small, the stress generated during the cutting process is reduced by more than 80% compared with the traditional one-time cutting method. The edge of the cut circuit board is flat and smooth, and the board surface is very flat without twisting or warping. And because of multiple cutting, the cutting process is very stable, which greatly improves the positioning ability of the V-CUT groove. Even if the circuit board with a very shallow V-CUT groove is cut, the aluminum plate will not be deformed after cutting to avoid defects.

[0044] In this embodiment, the travel distance between the upper and lower blades, i.e., the upper and lower tool openings, is adjustable within a range of 0.3-3 mm, which is safe to operate and is convenient for cutting circuit boards of different thicknesses.

[0045] When in use, the personnel place the circuit board to be cut on the surface of the positioning member 5 and rotate the three groups of transmission members 34 respectively, so that the moving member 32 drives the upper cutter 4 to adjust the position. When the moving member 32 moves up or down, the infrared light of the infrared ranging sensor 33 measures the distance after the moving member 32 is displaced, and transmits the spacing data between each group of cutters to the display panel 36 for the personnel to observe, so that the spacing between the subsequent three groups of cutting blades decreases from left to right, wherein the upper and lower spacing range of each group of blades is 0.3-3mm. After the spacing adjustment is completed, the personnel starts the driving motor of the upper cutter 4 and pushes the circuit board to be cut into the side cutting member of the positioning member 5 to cut it.

[0046] See also Figure 1-4The moving member 32 includes a moving block 321 provided between the inner walls of the slide groove 31, a through hole 322 is provided at the front end of the moving block 321, and the through hole 322 is used for the through installation of the transmission shaft of the upper slice 4. The upper end of the moving block 321 is fixedly connected with a bracket 323, and the bracket 323 is slidably connected to the inner wall of the slide groove 31. The upper end of the bracket 323 is provided with a threaded hole 324 that matches the transmission member 34.

[0047] More specifically, the transmission member 34 includes a limit block 343 rotatably connected to the upper end of the slide groove 31, and the lower end of the limit block 343 is fixedly connected to a threaded rod 341, and the threaded rod 341 penetrates between the inner walls of the slide groove 31 and is threadedly connected to the threaded hole 324, and the bottom end of the threaded rod 341 is fixedly connected to a limit block 342, and the limit block 342 is located between the inner walls of the bracket 323, and the upper end of the limit block 343 is fixedly connected to an adjusting sleeve 344.

[0048] During use of the present solution, the threaded rod 341 is inserted through the upper side of the slide groove 31, and the limit block 342 connected thereto is located between the inner walls of the bracket 323, and the threaded rod 341 is threadedly connected to the threaded hole 324, so that when a person rotates the adjustment sleeve 344, the threaded rod 341 rotates synchronously, and the limit block 343 cannot rotate due to the limit of the slide groove 31, so that the moving member 32 as a whole can make a linear motion up and down under the rotation of the transmission member 34, so that the spacing of the upper slice 4 connected to the outer side of the moving member 32 can be adjusted;

[0049] The through hole 322 can be used as an insertion end of the transmission shaft of the upper slicer 4, and a motor is installed on the rear side to drive the upper slicer 4 to perform a rotational cutting operation.

[0050] See also Figure 1 and Figure 5 The positioning member 5 includes two limiting holes 51 opened at the upper end of the workbench 1, and a positioning block 52 is slidably connected between the inner walls of the limiting holes 51. The bottom end of the positioning block 52 is fixedly connected to a limiting block 3 53. A limiting plate 54 is provided on the upper side of the positioning block 52. Two plug holes 55 corresponding to the limiting holes 51 are opened at the upper end of the limiting plate 54. A threaded rod 2 56 is installed through the inner walls of the plug holes 55. One end of the threaded rod 2 56 is threadedly connected to the positioning block 52, and an adjusting sleeve 2 57 is fixedly connected to the upper end of the threaded rod 2 56.

[0051] During the use of this scheme, since the gaps between the LED lamp beads distributed on various circuit boards are different, in order to facilitate the application range of the existing circuit board cutting to be wider, in this embodiment, based on the unchanged position of the cutting blade, by rotating the adjusting sleeve 2 57, the positioning block 52 is limited by the limiting hole 51, so that the positioning block 52 and the adjusting sleeve 2 57 move relative to each other, so that the limiting plate 54 is no longer limited by the pressure above the workbench 1. At this time, the personnel can fit the circuit board to be cut on the front side of the limiting plate 54, and align the V-shaped groove of the circuit board to be cut with the upper slice 4. As the adjusting sleeve 2 57 is rotated in the opposite direction, so that the adjusting sleeve 2 57 moves downward, the limiting plate 54 is positioned again, thereby completing the adjustment of the V-shaped groove spacing between each group of LED lamp beads on the circuit board for subsequent cutting work, which greatly improves the work efficiency of the personnel.

[0052] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
