Description

Technical Field

[0001] The present application relates to the technical field of panel separation equipment, and in particular to a panel separation machine for a COB substrate. Background Art

[0002] COB technology is an emerging LED packaging technology. Different from the traditional SMD surface mount packaging, it integrates the light-emitting chip into the PCB board instead of soldering it one by one on the PCB board. COB effectively improves the light color of the LED display, reduces risks and reduces costs.

[0003] A number of lamp beads are arranged in a rectangular array on the surface of the COB substrate, and a separation seam is provided between two adjacent lamp beads to facilitate separation of the COB substrate. When the COB substrate needs to be separated, the staff generally needs to manually separate the COB substrate.

[0004] However, manual separation operation is inefficient and can easily break the gold wires on the COB substrate or damage the chip joints. To solve this problem, some board separation equipment has appeared on the market to replace manual operation. However, a COB substrate is provided with a number of individual lamp bead units arranged horizontally and vertically. To separate all these lamp bead units separately using equipment, it is usually necessary to transport, operate and break the COB substrate multiple times to complete the separation of all the lamp beads. Therefore, the board separation equipment must include a vertical feeding mechanism, a horizontal conveying platform, and an up and down lifting mechanism for transportation.

[0005] Various lifting mechanisms and transfer mechanisms are generally set on the rack panel of existing panel separation equipment. Since various processes need to be operated, the multi-level cross-over stacking between various mechanisms not only makes the structure bloated and the operation process complicated, but also due to the multiple levels of stacking, the layout of various power mechanisms and line devices on the panel is chaotic, which is not only inconvenient to operate, but also has low panel separation efficiency, is prone to failure, and is difficult to maintain. In addition, the equipment has low integration, poor aesthetics, and lacks market competitiveness. Summary of the invention

[0006] In order to improve the integration, aesthetics and overall structural compactness of the panel separation equipment, and to have a neat layout for easy operation, monitoring and maintenance, the present application provides a panel separation machine for a COB substrate.

It should be noted that the transfer planes of the stripping device 6, the blocking device 7 and the material receiving device 8 are basically located at the same horizontal plane and are all located between the panel 2 and the lifting platform 3, so that the operation process of the COB substrate is clear and convenient for the operation, monitoring and maintenance of the board separator. In addition, the panel 2 is also provided with a first drive mechanism 91 for providing power for conveying COB substrates, a second drive mechanism 101 for providing power for conveying strip-shaped COB substrates, and a third drive mechanism 111 for providing power for conveying substrate units. The first drive mechanism 91, the second drive mechanism 101 and the third drive mechanism 111 are all located in the frame 1 below the panel 2 to keep the panel 2 clean and tidy, and are conducive to improving the integration, aesthetics and overall structural compactness of the board separator.

[0047] Reference Figure 1 and Figure 2 The feeding device 5 includes a rodless cylinder 51 arranged vertically on the side of the frame 1, the rodless cylinder 51 is connected to a vertically arranged slide 52, and a plurality of support seats 53 for placing the material frame 19 are arranged vertically on the slide 52. A horizontal pushing mechanism 54 located on the panel 2 is arranged on the side of one end of the support seat 53, and a first feeding device 9 for conveying the COB substrate to the stripping device 6 is arranged on the side of the other end of the support seat 53. The first driving mechanism 91 is included in the first feeding device 9 to provide power for conveying the COB substrate to the stripping device 6.

There is space for placing the material frame 19 between the fixing plate 122 and the rodless cylinder 51.

[0050] When it is necessary to place the material frame 19 on the support seat 53, the staff rotates the adjusting bolt 123 so that the adjusting bolt 123 drives the fixing plate 122 to move away from the rodless cylinder 51, and the space between the fixing plate 122 and the rodless cylinder 51 becomes larger to facilitate placing the material frame 19 on the support seat 53. When the material frame 19 is placed on the support seat 53, the staff rotates the adjusting bolt 123 in the opposite direction so that the adjusting bolt 123 drives the fixing plate 122 to move close to the rodless cylinder 51, and the fixing plate 122 cooperates with the slide plate 52 to clamp the material frame 19 to fix the material frame 19 on the support seat 53.

Specifically, the pushing motor 542 is horizontally fixedly arranged at the bottom of the protective cover 541, the first driving gear 543 and the first driven gear 544 are vertically rotatably connected to the side wall inside the protective cover 541, and the first driving gear 543 is fixedly sleeved on the output shaft of the pushing motor 542, the first toothed belt 545 is meshed around the first driving gear 543 and the first driven gear 544, and the pushing plate 546 is horizontally fixedly connected to the rack, and the pushing plate 546 points to the COB substrate in the material frame 19 in the horizontal direction. It should be noted that a through hole is provided on the side wall of the protective cover 541 close to the rodless cylinder 51 for the push plate 546 to pass through horizontally, so that the push plate 546 can push the COB substrate in the material frame 19 into the first feeding device 9 after passing through the protective cover 541. In other embodiments, a cylinder can also be used to provide power to the push plate 546, as long as the push plate 546 can be moved linearly in the horizontal direction, which will not be described in detail here.

Specifically, the first support plate 92 is horizontally fitted on the surface of the panel 2, and the first support plate 92 is vertically arranged with the push plate 546. The head end of the first support plate 92 is close to the rodless cylinder 51, and the tail end of the first support plate 92 is close to the slitting device 6. The first driving mechanism 91 is used to drive the first push plate 93 to reciprocate along the head and tail ends of the first support plate 92. The first driving mechanism 91 is driven by a structure of a motor, a screw rod and a connecting block.
