Referring to fig. 1-3, the dimensions of the bracket 300 and the cover plate 920 are both adapted to the PCBA jointed boards 910, when the PCBA jointed boards 910 with different specifications are processed, the second driving member 711 is utilized to adjust the space between the two clamping side plates 720, so that the clamping arms 850 of the clamping side plates 720 fix the cover plate 920, the stability of the cover plate 920 on the clamping frame 700 is ensured, and meanwhile, the clamping frame 700 can be adapted to the cover plates 920 with various specifications, thereby improving the utilization rate of the board splitting machine.

Referring to fig. 3 and 4, each clamping jaw mechanism 800 further includes a fixing bracket 810, a first driving member 820, a pushing block 830, and two connecting blocks 840, wherein the fixing bracket 810 is a frame structure, and is fixed to the bottom of the clamping side plate 720 by fastening screws, so as to support other components of the clamping jaw mechanism 800. The housing of the first driving member 820 is provided on the fixing bracket 810, and its protruding shaft can be horizontally moved toward or away from the clamping side plate 720. The first driving member 820 of the present application is preferably a linear motor or a cylinder.

Referring to fig. 3 and 4, the push block 830 has a trapezoid structure, wherein the cross-sectional area of the bottom of the push block 830 is larger than the cross-sectional area of the top thereof. The bottom of the push block 830 is fixed to the protruding shaft of the first driving member 820, so that the push block 830 is driven to move in the horizontal direction by the first driving member 820. The two connecting blocks 840 are respectively fixed to the two support arms, meanwhile, the connecting blocks 840 are embedded into the fixing support 810, a limiting protrusion is arranged on the surface of each connecting block 840 along the vertical direction, a limiting clamping groove is correspondingly formed in each fixing support 810, the limiting protrusions can be embedded into the limiting clamping grooves, and therefore the connecting blocks 840 are limited to be connected to the fixing supports 810 along the vertical direction in a sliding mode.

The two connection blocks 840 are symmetrically arranged with respect to the center of the push block 830, the surface of each connection block 840 facing the center of the fixed bracket 810 is an inclined plane, and the two inclined planes of the two connection blocks 840 are relatively distributed, and the distance between the two inclined planes gradually decreases along the extending direction of the extending shaft of the first driving member 820, so that a trapezoid space is formed between the two inclined planes.

When the first driving member 820 drives the pushing block 830 to extend, the pushing block 830 gradually moves between the two connecting blocks 840, and the pushing block 830 applies a pushing force to the two connecting blocks 840 respectively because the inclined surfaces of the two connecting blocks 840 gradually approach each other along the extending direction, so that the two connecting blocks 840 gradually move away from each other to drive the two clamping arms 850 to move in opposite directions. When the first driving member 820 pulls the pushing block 830 to retract, the pushing block 830 gradually moves away from the connecting blocks 840, and since the inclined surfaces of the two connecting blocks 840 gradually move away from each other along the retracting direction, the pushing block 830 applies a pulling force to the two connecting blocks 840, so that the two connecting blocks 840 gradually move closer together to drive the two clamping arms 850 to move in opposite directions.

Referring to fig. 1 and 2, an inductor 721 is disposed on the clamping side plate 720 for detecting whether the cover plate 920 is placed on the clamping assembly, so as to facilitate timely feeding of the cover plate 920.

Referring to fig. 1, the board splitting machine further includes a locking assembly that can fix the cover 920 to the bracket 300 when the cover 920 is placed over the bracket 300, so as to facilitate subsequent turning and processing of the PCBA boards 910.

Referring to fig. 7, the locking assembly includes a main shaft 400, a linkage rod 500 and a pressing plate 520, wherein a central shaft of the main shaft 400 is disposed along a horizontal direction, one end of the central shaft is inserted into a side of the bracket 300 and rotatably connected to the bracket 300, a steering engine 420 is disposed at a bottom or inside of the bracket 300, and a driving shaft of the steering engine 420 is connected to the main shaft 400, so as to drive the main shaft 400 to rotate along the central shaft.

Referring to fig. 7 and 8, the portion of the main shaft 400 extending from the bracket 300 is provided with a spiral protrusion 410, and the protrusion 410 extends from the end of the main shaft 400 to the middle of the main shaft 400 in the axial direction, and the protrusion 410 includes a first end 411 located at the end of the main shaft 400 and a second end 412 located at the middle of the main shaft 400. The spiral radius of the protrusion 410 gradually decreases in a direction approaching the bracket 300, i.e., the spiral radius of the first end 411 is larger than the spiral radius of the second end 412.

Referring to fig. 7-9, the linkage rod 500 has a cylindrical structure, a central axis of the linkage rod 500 is disposed along a vertical direction, a pressing plate 520 is connected to a top end of the linkage rod, and a roller 510 is rotatably disposed at a bottom end of the linkage rod. The roller 510 is engaged with the edge of the protrusion 410, and when the spindle 400 drives the protrusion 410 to rotate along the central axis thereof, the roller 510 can move along the edge of the protrusion 410. When the roller 510 rolls from the first end 411 to the second end 412 of the protrusion 410, the radius of the thread of the protrusion 410 gradually decreases in the direction from the first end 411 to the second end 412, so that the link 500 and the pressing plate 520 gradually descend in the vertical direction while gradually approaching the bracket 300. When the roller 510 moves to the second end 412 of the protrusion 410 in the present application, the pressing plate 520 is pressed against the surface of the cover plate 920, and since the main shaft 400 is coupled to the sidewall of the bracket 300, the pressing plate 520 applies a pressing force to the cover plate 920. Because the steering engine 420 has a certain self-locking function, when the pressing plate 520 is abutted to the surface of the cover plate 920, the steering engine 420 can control the main shaft 400 to stop rotating, so that the cover plate 920 and the bracket 300 are relatively fixed by using the locking assembly.

Referring to fig. 7-9, the locking assembly further includes a reinforcing rod 530, wherein a central axis of the reinforcing rod 530 is perpendicular to a central axis of the linking rod 500, one end of the reinforcing rod 530 is sleeved on a side wall of the linking rod 500, and the other end of the reinforcing rod 530 is movably inserted into the bracket 300. The link 500 is movable in a vertical direction with respect to the reinforcing bar 530, so that the movement direction of the link 500 is restricted by the reinforcing bar 530. When the roller 510 rolls from the first end 411 to the second end 412 of the protrusion 410, the link 500 gradually approaches the bracket 300, and at this time, the link 500 applies a pushing force to the reinforcing rod 530, so that the reinforcing rod 530 extends into the bracket 300 along the axial direction thereof.

Referring to fig. 7, a friction layer (not shown) is attached to the lower surface of the pressing plate 520, and the friction layer is preferably made of rubber or silica gel. The friction layer may increase friction between the pressing plate 520 and the cover plate 920 (see fig. 1), thereby improving stability and reliability of the cover plate 920 when fixed to the bracket 300. Meanwhile, the friction layer can avoid rigid pressing of the pressing plate 520 and the cover plate 920, so that the pressing plate 520 and the cover plate 920 are protected to a certain extent.

Referring to fig. 7, the upper surface of the bracket 300 is provided with a plurality of limiting posts 310, and the cover plate 920 (referring to fig. 1) is correspondingly provided with a plurality of limiting holes, wherein the limiting posts 310 are in one-to-one correspondence with the limiting holes. When the cover plate 920 is attached to the surface of the bracket 300, the limiting posts 310 can correspondingly penetrate into the limiting holes.

Based on the jogging of the limit posts 310 and the limit holes, the assembly precision of the cover plate 920 and the bracket 300 can be increased, meanwhile, the acting force between the cover plate 920 and the bracket 300 is also enhanced, and the reliability of the cover plate 920 and the bracket 300 when fixed is improved.

Referring to fig. 1-9, in an initial state, the carrier 300 is positioned at the discharging station 110, and a manipulator or a hand places the PCBA splice plate 910 on the surface of the carrier 300, while the cover plate 920 is fixed by the clamping arms 850 of the clamping jaw mechanism 800; then, the linear assembly 200 is used to drive the bracket 300 and the PCBA board 910 to move to the assembly station 120, and the third driving member 610 provided on the supporting frame 600 pushes the clamping assembly to move downward, so that the cover plate 920 gradually approaches the bracket 300. When the cover plate 920 is attached to the surface of the bracket 300, the first driving member 820 drives the pushing block 830 to extend, and the pushing block 830 applies a pushing force to the two connecting blocks 840, so that the two clamping arms 850 move oppositely, and the clamping jaw mechanism 800 is separated from the cover plate 920. The second driving member 711 provided on the clamping top plate 710 pushes the two clamping side plates 720 to move back to back, and the third driving member 610 drives the clamping assembly to retract, so as to avoid interference between the clamping jaw mechanism 800 and the placed cover plate 920.

The steering engine 420 drives the main shaft 400 to rotate, so that when the roller 510 moves along the first end 411 of the protrusion 410 to the second end 412 thereof, the linkage rod 500 moves downwards synchronously with the pressing plate 520 and gradually approaches the bracket 300 at the same time; when the roller 510 moves to the second end 412, the pressing plate 520 is pressed against the surface of the cover 920, thereby achieving the relative fixation of the cover 920 and the bracket 300. The carriage 300 and cover plate 920 are then driven by the linear assembly 200 to the discharge station 110 for transfer to subsequent processing.

Referring to fig. 1 to 9, the clamping assembly is disposed above the bracket 300 through the lifting assembly, and meanwhile, the linear assembly 200 can drive the bracket 300 to reciprocate between the discharging station 110 and the assembling station 120, so that the speed and acceleration of the movement of the bracket 300 can be improved; meanwhile, the cable abrasion risk is reduced, the maintenance cost of equipment is reduced, and the running stability of the equipment is improved.

The spiral protrusion 410 on the main shaft 400 is used to push the linkage rod 500 and the pressing plate 520 to move in the vertical direction and the horizontal direction at the same time, and when the cover plate 920 is assembled with the bracket 300, the pressing plate 520 is far away from the bracket 300 in the vertical direction and the horizontal direction so as to avoid interference with the clamping assembly. When the assembly of the cover plate 920 with the bracket 300 is completed, the pressing plate 520 may be simultaneously close to the cover plate 920 in the vertical direction as well as in the horizontal direction, thereby improving the assembly efficiency of the cover plate 920 with the bracket 300.
