To solve the above problems, the present application provides a position adjusting mechanism 100, as shown in fig. 1 to 4, the position adjusting mechanism 100 includes a mounting base 10, a carrier plate 11, a plurality of locking structures 12, a first adjusting assembly 13, and a second adjusting assembly 14. The carrying plate 11 is mounted on the top of the mounting base 10, and the carrying plate 11 is used for carrying a board 900 to be processed, wherein the board 900 to be processed includes a first side 90 and a second side 91 adjacent to the first side 90. A plurality of locking structures 12 are connected to the carrier plate 11 and the mount 10 to lock the mount 10 and the carrier plate 11 in the thickness direction (Z direction in fig. 1) of the carrier plate 11. The first adjusting component 13 includes a first driving component 131 and a first adjusting block 132, the first adjusting block 132 is mounted on a first side of the carrier plate 11, the first adjusting block 132 is used for abutting against the first side edge 90, and the first adjusting component 13 is mounted on the mounting seat 10 and connected with the first adjusting block 132 to drive the first adjusting block 132 to move in a first direction (X direction in fig. 1). The second adjusting assembly 14 includes a second rotary driving assembly and a second adjusting block 142, the second adjusting block 142 is mounted on the second side of the carrier plate 11, the second adjusting block 142 is used for abutting against the second side 91, and the second adjusting assembly 14 is mounted on the mounting base 10 and connected to the second adjusting block 142 to drive the second adjusting block 142 to move in the second direction (Y direction in fig. 1). The thickness direction of the carrying plate 11 is perpendicular to the first direction and the second direction, and the first direction and the second direction are disposed at an included angle.

When the position adjusting mechanism 100 of the present embodiment is used, the plate 900 to be processed is only required to be placed on the carrier plate 11, and then the positions of the plate 900 to be processed in the first direction and the second direction are adjusted by the first adjusting component 13 and the second adjusting component 14, so as to avoid the deviation of the plate 900 to be processed.

Specifically, the first driving component 131 can drive the first adjusting block 132 to move in the first direction, and the first adjusting block 132 can be abutted against the first side edge 90 of the board 900 to be processed, so that the first adjusting block 132 can drive the board 900 to be processed to move in the first direction when moving, thereby adjusting the distance of the board 900 to be processed in the first direction; the second driving assembly 141 can drive the second adjusting block 142 to move in the second direction, and the second adjusting block 142 can be abutted against the second side edge 91 of the board 900 to be processed, so that the second adjusting block 142 can drive the board 900 to be processed to move in the second direction when moving, thereby adjusting the distance between the board 900 to be processed in the second direction.

Since the position adjusting mechanism 100 of the present embodiment is provided with the plurality of locking structures 12 connected with the carrier plate 11 and the mounting base 10, the plurality of locking structures 12 can lock the mounting base 10 and the carrier plate 11 in the thickness direction of the carrier plate 11, so the plurality of locking structures 12 can limit the deformation of the carrier plate 11 in the thickness direction thereof, thereby avoiding the situation that the plate 900 to be processed cannot be laid flat, the local friction between the plate 900 to be processed and the carrier plate 11 is increased, the first adjusting block 132 and the second adjusting block 142 cannot normally contact the plate 900 to be processed, and the like, effectively guaranteeing the processing quality, and prolonging the service life of the position adjusting mechanism 100.

It should be noted that, the position adjusting mechanism 100 of the present embodiment is mainly used for adjusting the relative position of the PCB boards, and a plurality of PCB boards can be placed on the carrier 11 at the same time. Of course, it is understood that the position adjustment mechanism 100 of the present embodiment may also be used to adjust the relative position of other boards 900 to be processed.

In some embodiments of the present application, the angle between the first direction and the second direction is 90 degrees, so that a rectangular plate can be adapted. Optionally, the angle between the first direction and the second direction is greater than 90 degrees, or less than 90 degrees, to accommodate sheet materials having edge angles other than right angles.

In some embodiments of the present application, referring to fig. 4, the position adjusting mechanism 100 further includes a moving assembly 15, the moving assembly 15 is mounted on the mounting base 10, the moving assembly 15 is connected to the carrying plate 11, and the moving assembly 15 is used for driving the carrying plate 11 to move in a third direction (N direction in fig. 3) perpendicular to a thickness direction of the carrying plate 11, so that the board 900 to be processed can approach the first adjusting block 132 and the second adjusting block 142.

Specifically, if the plate 900 to be processed is positioned only by the first adjusting assembly 13 and the second adjusting assembly 14, the stroke of the first driving assembly 131 and the second driving assembly 141 needs to be relatively large, and the reliability of the structure is poor. After the moving assembly 15 is arranged, before the position of the plate 900 to be processed is adjusted by the first adjusting assembly 13 and the second adjusting assembly 14, the moving assembly 15 is utilized to drive the bearing plate 11 to move in the third direction, so that the plate 900 to be processed can approach to the first adjusting block 132 and the second adjusting block 142, and thus, the strokes of the first driving assembly 131 and the second driving assembly 141 can be effectively shortened, and the reliability of the structure can be effectively improved.

In some embodiments of the present application, referring to fig. 2 and 5-7, a mounting hole is formed on a side of the mounting base 10 facing the carrying plate 11, and the locking structure 12 includes a mounting frame 121, a roller 122 and a fixing member 123. The roller 122 can be rotatably connected to the mounting frame 121, and the rotation axis of the roller 122 is perpendicular to the thickness direction and the third direction of the bearing plate 11, the roller 122 is abutted to the bearing plate 11, and the fixing member 123 is sequentially inserted into the mounting frame 121 and the mounting hole.

Specifically, since the locking structure 12 can lock the mount 10 and the carrier plate 11 in the thickness direction of the carrier plate 11, the locking structure 12 also moves in the third direction relative to one of the carrier plate 11 or the mount 10 when the moving assembly drives the carrier plate 11 to move in the third direction.

In this embodiment, when the moving assembly drives the carrier plate 11 to move in the third direction, the locking structure 12 can be limited by the fixing member 123 and stay in place, so that the carrier plate 11 moves in the third direction, and the locking structure 12 moves relative to the carrier plate 11. Since the roller 122 is abutted against the bearing plate 11, the roller 122 can apply a force to the bearing plate 11 to lock the mounting seat 10 and the bearing plate 11 in the thickness direction of the bearing plate 11, and since the rotation axis of the roller 122 is perpendicular to the thickness direction and the third direction of the bearing plate 11 respectively, when the moving assembly drives the bearing plate 11 to move in the third direction, the roller 122 rolls on the bearing plate 11, and since the friction force between the roller 122 and the bearing plate 11 is a rolling friction force which is much smaller than the sliding friction force, the wear speed of the bearing plate 11 and the locking structure 12 can be reduced, and therefore, after implementing the embodiment, the service lives of the locking structure 12 and the bearing plate 11 are longer.

Referring to fig. 5, in some embodiments, two rollers 122 are disposed on each mounting frame 121, the two rollers 122 are disposed on two sides of the mounting frame 121 along the third direction, and the fixing member 123 is inserted between the two rollers 122.

In particular, the purpose of mounting two rollers 122 on each side of the mounting frame 121 in the third direction is to provide better balance and stability, and the relative positions of the two wheels can help to disperse the weight and maintain balance. The reason for arranging the fixing member 123 between the two rollers 122 is that the pressure exerted by the rollers 122 on the carrier plate 11 is derived from the fixing member 123, and arranging the fixing member 123 between the two rollers 122 enables the locking structure 12 to exert a more uniform pressure on the carrier plate 11.

Referring to fig. 5, in some embodiments, the locking structure 12 includes two securing members 123, the two securing members 123 being spaced apart in a third direction.

Compared to the embodiment having only one fixing member 123, the present embodiment can increase the installation stability of the locking structure 12, and only the two fixing members 123 are loosened at the same time, so that the locking structure 12 is loosened as a whole.

Referring to fig. 2, in an embodiment, the carrying plate 11 is further provided with a sink 111, the sink 111 extends along a third direction, the rollers 122 and the mounting frame 121 are both sleeved in the sink 111, one end of the fixing member 123 is connected to the mounting frame 121, the other end of the fixing member 123 is in threaded connection with the mounting hole, and the carrying plate 11 is slidably connected with the mounting frame 121 along the length direction of the sink 111 through the fixing member 123. The head of the pin is arranged in the sinking groove 111, and the tail of the pin penetrates out of the sinking groove 111 and is inserted into the mounting hole.

Specifically, if the locking structure 12 protrudes from the carrier plate 11, the locking structure 12 may jack up the plate 900 to be processed once abutting against the bottom of the plate 900 to be processed, and in order to avoid this situation, the embodiment is provided with the sink 111, and the sink 111 may be used to accommodate the locking structure 12, so as to avoid the situation that the locking structure 12 protrudes from the carrier plate 11.

In one embodiment, the first adjusting assembly 13 further includes a third adjusting block 134, the third adjusting block 134 is mounted on the first side of the carrier plate 11 and located on a side of the first adjusting block 132 away from the second adjusting block 142, and the third lump is used to abut against the first side edge 90. The third driving assembly 133 is mounted on the mounting base 10 and connected to the third adjusting block 134 to drive the third adjusting block 134 to move in the first direction.

The third adjusting block 134 of the embodiment can cooperate with the first adjusting block 132 to adjust the position of the board 900 to be processed in the first direction, so as to improve the accuracy of position adjustment.

Referring to fig. 1 and 4, in a specific embodiment, the first adjusting assembly 13 further includes a fourth adjusting block 144, the fourth adjusting block 144 is mounted on the first side of the carrier 11 and located on a side of the second adjusting block 142 near the first adjusting block 132, and the fourth adjusting block 144 is configured to abut against the second side 91. The fourth driving component 143 is mounted on the mounting base 10 and connected to the fourth adjusting block 144 to drive the fourth adjusting block 144 to move in the second direction.

The fourth adjusting block 144 of the embodiment can cooperate with the second adjusting block 142 to adjust the position of the board 900 to be processed in the second direction, thereby improving the accuracy of position adjustment.

Referring to fig. 3, in a specific embodiment, the stroke of the first driving assembly 131 is smaller than the stroke of the third driving assembly 133, and the stroke of the second driving assembly 141 is smaller than the stroke of the fourth driving assembly 143.

By implementing the present embodiment, the deflection angle of the plate 900 to be processed can be adjusted by using the second adjusting block 142 and the fourth adjusting block 144. Specifically, since the stroke of the first driving component 131 is smaller than that of the third driving component 133, after the first adjusting block 132 completes moving, the third adjusting block 134 still moves continuously, so as to drive the board 900 to be processed to deflect a certain angle; similarly, the stroke of the second driving component 141 is smaller than that of the fourth driving component 143, so after the second adjusting block 142 completes moving, the fourth adjusting block 144 still moves continuously, and further drives the board 900 to be processed to deflect a certain angle. Thus, by implementing the present embodiment, the deflection angle of the plate 900 to be processed can be adjusted by using the second and fourth adjustment blocks 142 and 144.

It should be noted that, when a plurality of boards to be processed 900 are stacked on the position adjusting mechanism 100 at the same time, the deflection angles of the plurality of boards to be processed 900 may not be the same, and by implementing the present embodiment, the deflection angles of the plurality of boards to be processed 900 may be adjusted to be the same.
