[0002] In PCB manufacturing, PCB laser imaging is a crucial step. Generally, graphic transfer is achieved using CAD technology, through-hole drilling, micro-hole drilling, or by constructing inner and outer layer circuit images, or by building resist layers. Existing PCB laser imaging structures typically use adhesive or screw / clip connections to fix the upper connection point to the laser head body. These connection methods are complex and cannot guarantee the laser head's straightness, easily affecting imaging quality. Therefore, publication number CN 210670788 U proposes an "alignment device for PCB laser imaging." Through the combined use of a top cover knob chuck, knob holder, chuck post, and circular slot, it not only facilitates quick connection and disassembly but also provides more accurate and faster alignment compared to similar connection devices.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0021] Example like Figure 1-6 As shown, the alignment device for PCB laser imaging proposed in this utility model includes a mounting base 1, a plurality of mounting rods 2 on the mounting base 1, an external interface 3 at the top of the rods 2, a top cover knob chuck 4 fixedly fixed at the lower end of the rods 2, a knob seat 5 below the top cover knob chuck 4, a laser head 6 for imaging below the knob seat 5, a disc 7 fixedly fixed at the top of the laser head 6, two rectangular blocks 8 on the outside of the disc 7, and two sets of limiting plates 9 at the bottom of the knob seat 5. Each rectangular block 8 is located between each set of limiting plates 9. The setting of the limiting plates 9 and the rectangular blocks 8 can limit the laser head 6 and prevent the laser head 6 from rotating. The bottom of the knob seat 5 is provided with two positioning structures 10 for fixing the laser head 6. The positioning structure 10 includes a limiting frame 101 for installation. A pressure plate 102 for limiting is movably disposed within the limiting frame 101. A locking block 103 is fixedly disposed on one side of the pressure plate 102. A locking frame 104 for locking is disposed on one inner wall of the limiting frame 101. The locking frame 104 includes a locking rod and a locking hook. Parallel inclined surfaces are provided on the sides of the locking hook and the locking block 103 that are close to each other. An installation groove 109 is provided on one inner wall of the limiting frame 101. A spring 105 is fixedly disposed within the installation groove 109. The other end of the spring 105 is in contact with the locking frame 104. Connecting rods 107 are fixedly disposed at the top and bottom of the locking frame 104. A horizontal plate 108 is movably disposed at the ends of the two connecting rods 107 that are far apart. Mounting holes are provided on the sides of the two horizontal plates 108 that are close to each other. Bearings are fixedly installed on both of the two bearings, and the inner rings of the two bearings are fitted onto the connecting rod 107. The other side of the horizontal plate 108 is fixedly connected to the inner wall of the limiting frame 101. A top rod 106 for rotating the locking frame 104 is movably installed on one side of the inner wall of the limiting frame 101. Slide grooves 1010 are provided on both sides of the inner wall of the limiting frame 101. Limiting strips 1011 are fixedly installed on both sides of the pressure plate 102. The two limiting strips 1011 are movably connected to the two slide grooves 1010 respectively. A bracket 1012 is fixedly installed on the top of the pressure plate 102. The bracket 1012 is "L" shaped and can play a limiting role. When the locking frame 104 is stuck on the locking block 103, one end of the bracket 1012 is attached to one side of the limiting frame 101, and the pressure plate 102 cannot move forward. The laser head 6 is provided with a protective structure 11 on its exterior. The protective structure 11 includes two arc-shaped plates 111 fixedly connected to the pressure plate 102. Both arc-shaped plates 111 are provided with threaded grooves on their exteriors. The same protective barrel 112 is movably provided on the exteriors of the two arc-shaped plates 111. The protective barrel 112 can not only block laser leakage, but also protect the laser head 6. The protective barrel 112 is covered with a rubber sleeve 113, which acts as a buffer and can reduce the impact force on the protective barrel 112 when it is subjected to external impact.
[0022] In this embodiment, when the laser head 6 needs to be removed, first rotate the protective barrel 112 counterclockwise to detach it from the two arc-shaped plates 111. Then, simultaneously press the two push rods 106, which drive the locking frame 104 to rotate and separate the locking hook from the locking block 103. Then, pull the two pressure plates 102 in a direction away from each other. After the two pressure plates 102 separate from the disc 7, the laser head 6 can be removed. During installation, place the disc 7 between the two sets of limiting plates 9 and let the two rectangular blocks 8 be locked in the two sets of limiting plates 9. Then, simultaneously push the two pressure plates 102 in a direction closer to each other. The two locking blocks 103 are driven, and the inclined surface of the locking block 103 is in contact with the inclined surface of the locking hook. When the inclined surface of the locking block 103 is separated from the inclined surface of the locking hook, the spring 105 causes the locking frame 104 to reset, and the locking hook is locked on the locking block 103, thereby positioning the pressure plate 102. At this time, the pressure plate 102 is in contact with the disc 7 and cannot move forward, thus realizing the installation of the laser head 6. Finally, the protective bucket 112 is put on the two arc plates 111 and rotated clockwise to fix the protective bucket 112 and the arc plates 111. This not only prevents the laser from leaking out and injuring the operator's eyes and skin, but also resists external impact forces and protects the laser head 6.
[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
