Description

Technical Field

[0001] This application specifically relates to the technical field of PCBA board splitting machines. Background Art

[0002] A PCBA board splitting machine is a mechanical device used to cut and separate PCBA panel boards. Compared with the board splitting methods of manual labor and pliers, the PCBA board splitting machine cuts the PCBA panel board through the movement of the blade, can more effectively control the stress generated during the PCBA board splitting process, and prevent the PCBA panel board from shifting or falling during board splitting; at the same time, it can improve the accuracy and efficiency of board splitting.

[0003] All the opening and closing mechanism components of the existing board splitting machine cover are integrated on the moving shaft of the tabletop. Therefore, a linear guide rail needs to be set on each side of the tabletop; at the same time, a cylinder moving up and down and a connecting mechanism component are set on the guide rail sliders on both sides. Each time the machine type is changed, the cover needs to be fixed to the cylinder moving up and down with bolts so that the cover can move up and down; a cylinder with a larger stroke is fixed on one side of the tabletop, and the other end is connected to the mechanism components on the guide rail sliders on both sides to drive the guide rail sliders on both sides to move back and forth.

[0004] Since all the mechanism components and electrical components are integrated on the moving shaft of the tabletop, a corresponding cable carrier needs to be added. Because all the cables and air pipes need to pass through the cable carrier and move back and forth with the tabletop, there may be a risk of intermittent sensor signals and cable wear over time, which will also increase the maintenance cost of the equipment. At the same time, integrating all the mechanism components on the moving tabletop will increase the load on the moving shaft of the tabletop, and the acceleration, deceleration, and moving speed of the moving shaft of the tabletop will be affected. Summary of the Invention

[0005] This application provides a board splitting machine to solve the technical problems that integrating all the mechanism components on the moving tabletop leads to a relatively large load on the moving shaft of the tabletop and the equipment is easily damaged.

The two connecting blocks are respectively slidably connected to both sides of the pushing block, so that the two inclined surfaces are respectively attached to both side surfaces of the pushing block. Wherein, each connecting block is fixed to one of the clamping arms. When the first driving member drives the pushing block to extend, the two clamping arms move away from each other.

[0030] The present application provides a circuit board splitting machine, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. And in the following embodiments, each embodiment has its own focus. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0031] Please refer to Figure 1 , the present application provides a circuit board splitting machine, which can fix the PCBA panel 910 by using the bracket 300 and the cover plate 920 to improve the accuracy of subsequent splitting of the PCBA panel 910. Among them, the above-mentioned bracket 300 is used to carry the PCBA panel 910 to be cut, and the cover plate 920 is used to press above the PCBA panel 910. The combination of the bracket 300 and the cover plate 920 can fix the PCBA panel 910, so that the position of the PCBA panel 910 will not shift or move during subsequent processes.

[0032] Please refer to Figure 1, the board splitting machine includes a workbench 100, a linear component 200 and a bracket 300. The above-mentioned workbench 100 includes a tabletop, which is divided into a feeding station 110 and an assembly station 120. The linear component 200 is installed on the tabletop, and the setting direction of the linear component 200 is along the direction from the feeding station 110 to the assembly station 120, so that a part of the linear component 200 is located at the feeding station 110 and the other part is located at the assembly station 120. In this embodiment, the linear component 200 is preferably a linear guide rail.

[0033] Please refer to Figure 1 , the linear component 200 includes a guide rail and a guide block embedded on the guide rail. The guide rail is installed on the tabletop along the direction from the feeding station 110 to the assembly station 120. The bracket 300 is installed on the guide block through fastening screws, so as to drive the bracket 300 and the PCBA panel 910 to reciprocate between the feeding station 110 and the assembly station 120 by using the linear component 200.

[0034] Please refer to Figure 1 , the board splitting machine further includes a lifting component, a clamping component and a locking component. The clamping component is used to clamp the cover plate 920; the lifting component is used to drive the clamping component to move in the vertical direction, so as to realize the assembly of the cover plate 920 and the bracket 300. The locking component is used to lock the assembled cover plate 920 and the bracket 300, so that the cover plate 920, the PCBA panel 910 and the bracket 300 are locked.

[0035] Please refer to Figure 1 and Figure 2 , the lifting component includes a support frame 600 and a third driving member 610. The support frame 600 is fixed at the assembly station 120 of the tabletop and is located above the linear component 200. The housing of the third driving member 610 is connected to the support frame 600, so that the third driving member 610 is fixed relative to the support frame 600; the extending shaft of the third driving member 610 faces the tabletop and is connected to the clamping component, so as to drive the clamping component to approach or move away from the bracket 300 in the vertical direction. In this application, the third driving member 610 is preferably a linear motor or a cylinder.

[0036] Please refer to Figure 2 and Figure 3 , the clamping component includes a clamping frame 700 and at least two jaw mechanisms 800. The clamping frame 700 includes a clamping top plate 710 and two clamping side plates 720. The central plane of the clamping top plate 710 is parallel to the tabletop, and the central planes of the two clamping side plates 720 are perpendicular to the central plane of the clamping top plate 710, and the two clamping side plates 720 are respectively connected to both sides of the clamping top plate 710. The jaw mechanisms 800 are symmetrically arranged at the bottom of the clamping side plates 720. When the clamping component clamps the cover plate 920 (refer to Figure 1When in the state of ( ), the two clamping side plates 720 are respectively located on both sides of the cover plate 920, and the clamping jaws mechanism 800 on the clamping side plates 720 is used to realize the relative fixation of the cover plate 920 and the clamping frame 700. In this application, a clamping jaws mechanism 800 is provided at the bottom of each clamping side plate 720. The two clamping jaws mechanisms 800 are respectively close to both ends of the clamping side plate 720 and are symmetrically arranged about the central axis of the clamping side plate 720.

[0037] Please refer to Figure 2 and Figure 3 Each clamping jaws mechanism 800 includes two clamping arms 850 arranged vertically. The two clamping arms 850 can move towards or away from each other in the vertical direction so as to clamp both sides of the cover plate 920, thereby locking the cover plate 920 by using the clamping frame 700. In this application, the vertical distance between the two clamping side plates 720 is equal to the width of the cover plate 920, and the vertical distance between the two clamping arms 850 is equal to the thickness of the cover plate 920.

[0038] Please refer to Figure 2 and Figure 3 At both ends of the clamping top plate 710, there are second driving members 711. The housing of the second driving member 711 is fixed to the upper surface of the clamping top plate 710. At the same time, the extending shafts of the two second driving members 711 are arranged in opposite directions and are respectively connected to the top ends of the clamping side plates 720 to drive the two clamping side plates 720 to move relative to the clamping top plate 710 by using the second driving member 711. In this application, the second driving member 711 is preferably a linear motor or a cylinder.

[0039] The top end of each clamping side plate 720 includes a through slot. Since the two clamping side plates 720 are respectively located on both sides of the clamping top plate 710, the two end portions of the clamping top plate 710 can pass through the two through slots, and the second driving member 711 is used to drive the clamping side plates 720 and the clamping top plate 710 to be slidably connected.

[0040] Please refer to Figures 1-3 The sizes of the bracket 300 and the cover plate 920 are both adapted to the PCBA panel 910. When processing PCBA panels 910 of different specifications, the distance between the two clamping side plates 720 is adjusted by using the second driving member 711 so that the clamping arms 850 of the clamping side plates 720 fix the cover plate 920, ensuring the stability of the cover plate 920 disposed on the clamping frame 700. At the same time, the clamping frame 700 can be adapted to cover plates 920 of multiple specifications, improving the utilization rate of the board splitter.

[0041] Please refer to Figure 3 and Figure 4, each jaw mechanism 800 further includes a fixed bracket 810, a first driving member 820, a push block 830, and two connecting blocks 840. The fixed bracket 810 is a frame structure, which is fixed to the bottom of the clamping side plate 720 by fastening screws and is used to support other components of the jaw mechanism 800. The housing of the first driving member 820 is arranged on the fixed bracket 810, and its protruding shaft can approach or depart from the clamping side plate 720 in the horizontal direction. In this application, the first driving member 820 is preferably a linear motor or a cylinder.

[0042] Please refer to Figure 3 and Figure 4 , the push block 830 is a trapezoidal structure, where the cross-sectional area of the bottom of the push block 830 is larger than that of its top. The bottom of the push block 830 is fixed to the protruding shaft of the first driving member 820, so as to drive the push block 830 to move in the horizontal direction by the first driving member 820. The two connecting blocks 840 are respectively fixed to the two arms. At the same time, the connecting blocks 840 are embedded in the fixed bracket 810, and a limiting protrusion is arranged on the surface of the connecting blocks 840 in the vertical direction. The corresponding fixed bracket 810 is provided with a limiting slot. The above-mentioned limiting protrusion can be embedded in the limiting slot, so as to limit the connecting block 840 to be slidably connected to the fixed bracket 810 in the vertical direction.

[0043] The two connecting blocks 840 are symmetrically arranged about the center of the push block 830. The surface of each connecting block 840 facing the center of the fixed bracket 810 is an inclined surface, and the two inclined surfaces of the two connecting blocks 840 are distributed oppositely. Along the extending direction of the protruding shaft of the first driving member 820, the distance between the two inclined surfaces gradually decreases, so that a trapezoidal space is formed between the two inclined surfaces. The two side walls of the connecting block 840 are respectively slidably connected to the two push blocks 830, so that the two inclined surfaces are respectively attached to the side walls of the push block 830.

[0044] Please refer to Figures 4-6 , a chute 841 is concavely formed in the inclined surface of the connecting block 840, and sliding blocks 831 are protrudingly arranged on the two side walls of the push block 830. The above-mentioned sliding blocks 831 can be embedded in the chute 841. By the cooperation of the sliding blocks 831 and the chute 841, the movement directions of the connecting block 840 and the clamping arm 850 can be restricted, and at the same time, the disengagement of the connecting block 840 and the push block 830 during movement can be avoided, improving the reliability and accuracy of the movement of the jaw mechanism 800.

[0045] 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. Since the inclined surfaces of the two connecting blocks 840 gradually approach along the extending direction, the pushing block 830 respectively applies a thrust to the two connecting blocks 840, causing the two connecting blocks 840 to gradually move away from each other, so as to drive the two clamping arms 850 to move away from each other. When the first driving member 820 pulls the pushing block 830 to retract, the pushing block 830 gradually moves away from the connecting block 840. Since the inclined surfaces of the two connecting blocks 840 gradually move away from each other along the retracting direction, the pushing block 830 respectively applies a pulling force to the two connecting blocks 840, causing the two connecting blocks 840 to gradually approach each other, so as to drive the two clamping arms 850 to move towards each other.

[0046] Please refer to Figure 1 and Figure 2 , a sensor 721 is provided on the clamping side plate 720 for detecting whether the cover plate 920 is placed on the clamping assembly, so as to facilitate the timely feeding of the cover plate 920.

[0047] Please refer to Figure 1 , the board splitting machine further includes a locking assembly. When the cover plate 920 is placed above the bracket 300, the locking assembly can fix the cover plate 920 and the bracket 300, so as to facilitate the subsequent transfer and processing of the PCBA panel 910.

[0048] Please refer to Figure 7 , the locking assembly includes a main shaft 400, a linkage rod 500 and a pressing plate 520. The central axis of the main shaft 400 is arranged horizontally, and one end of it is inserted into the side of the bracket 300 and is rotatably connected to the bracket 300. In this application, a servo motor 420 is provided at the bottom or inside of the bracket 300, and the driving shaft of the servo motor 420 is connected to the main shaft 400, so as to drive the main shaft 400 to rotate along its central axis.

[0049] Please refer to Figure 7 and Figure 8 , a spiral protrusion 410 is provided on the part of the main shaft 400 extending out of the bracket 300. The protrusion 410 extends axially from the end of the main shaft 400 to the middle of the main shaft 400. The above 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. Along the direction close to the bracket 300, the spiral radius of the protrusion 410 gradually decreases, that is, the spiral radius of the first end 411 is greater than the spiral radius of the second end 412.

[0050] Please refer to Figures 7-9, the linkage rod 500 is a cylindrical structure. The central axis of the linkage rod 500 is arranged vertically. A pressing plate 520 is connected to its top end, and a roller 510 is rotatably arranged at its bottom end. The above roller 510 is stuck to the edge of the protrusion 410. When the main shaft 400 drives the protrusion 410 to rotate along its central axis, 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, since the thread radius of the protrusion 410 gradually decreases along the direction from the first end 411 to the second end 412, the linkage rod 500 and the pressing plate 520 gradually descend vertically and gradually approach the bracket 300 at the same time. In this application, when the roller 510 moves to the second end 412 of the protrusion 410, the pressing plate 520 presses on the surface of the cover plate 920. Since the main shaft 400 is connected to the side wall of the bracket 300, the pressing plate 520 exerts a pressure on the cover plate 920. Since the servo motor 420 has a certain self-locking function, when the pressing plate 520 abuts against the surface of the cover plate 920, the servo motor 420 can control the main shaft 400 to stop rotating, so that the relative fixation of the cover plate 920 and the bracket 300 is realized by using the locking component.

[0051] Please refer to Figures 7-9 , the locking component further includes a reinforcing rod 530. The central axis of the above reinforcing rod 530 is perpendicular to the central axis of the linkage rod 500. One end of the reinforcing rod 530 is sleeved on the side wall of the linkage rod 500, and the other end is movably penetrated into the bracket 300. The linkage rod 500 can move vertically relative to the reinforcing rod 530, so as to limit the movement direction of the linkage rod 500 by using the reinforcing rod 530. When the roller 510 rolls from the first end 411 to the second end 412 of the protrusion 410, the linkage rod 500 gradually approaches the bracket 300. At this time, the linkage rod 500 exerts a thrust on the reinforcing rod 530, so that the reinforcing rod 530 extends into the bracket 300 along its axial direction.

[0052] Please refer to Figure 7 , a friction layer (not shown in the figure) is attached to the lower surface of the pressing plate 520. In this application, the material of the friction layer is preferably rubber or silica gel. The friction layer can increase the friction force between the pressing plate 520 and the cover plate 920 (refer to Figure 1 ), so as to improve the stability and reliability when the cover plate 920 and the bracket 300 are fixed. At the same time, the friction layer can avoid the rigid pressing of the pressing plate 520 and the cover plate 920, so it has a certain protective effect on both the pressing plate 520 and the cover plate 920.

[0053] Please refer to Figure 7 , a plurality of limit posts 310 are arranged on the upper surface of the bracket 300, and the cover plate 920 (refer to Figure 1A number of limiting holes are correspondingly provided, and the above-mentioned limiting posts 310 correspond to the limiting holes one by one. When the cover plate 920 is attached to the surface of the bracket 300, the limiting posts 310 can correspondingly pass through the limiting holes.

[0054] Based on the fitting of the limiting posts 310 and the limiting holes, the assembly accuracy of the cover plate 920 and the bracket 300 can be increased. At the same time, the acting force between the cover plate 920 and the bracket 300 is also strengthened, and the reliability when the cover plate 920 and the bracket 300 are fixed is improved.

[0055] Please refer to Figures 1-9 , in the initial state, the bracket 300 is located at the feeding station 110. The manipulator or manual operator places the PCBA panel 910 on the surface of the bracket 300, and at the same time, the cover plate 920 is fixed by the clamping arm 850 of the clamping jaw mechanism 800. Then, the linear component 200 is used to drive the bracket 300 and the PCBA panel 910 to move to the assembly station 120. The third driving member 610 provided on the support frame 600 pushes the clamping component 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, when the first driving member 820 drives the push block 830 to extend, the push block 830 applies a thrust to the two connecting blocks 840, so that the two clamping arms 850 move away from each other, thereby separating the clamping jaw mechanism 800 from the cover plate 920. Then, the second driving member 711 provided on the clamping top plate 710 pushes the two clamping side plates 720 to move away from each other, and at the same time, the third driving member 610 drives the clamping component to retract, so as to avoid interference between the clamping jaw mechanism 800 and the placed cover plate 920.

[0056] The servo motor 420 drives the main shaft 400 to rotate. When the roller 510 moves along the first end 411 of the protrusion 410 to its second end 412, the linkage rod 500 and the pressing plate 520 move downward synchronously and gradually approach the bracket 300 at the same time. When the roller 510 moves to the second end 412, the pressing plate 520 presses on the surface of the cover plate 920, thereby realizing the relative fixation of the cover plate 920 and the bracket 300. Then, the linear component 200 is used to drive the bracket 300 and the cover plate 920 to move to the feeding station 110, so as to be transferred to the subsequent process.

[0057] Please refer to Figures 1-9 , the clamping component is arranged above the bracket 300 through the lifting component. At the same time, the linear component 200 can drive the bracket 300 to reciprocate between the feeding station 110 and the assembly station 120, thereby improving the movement speed and acceleration of the bracket 300; at the same time, reducing the risk of cable wear, reducing the maintenance cost of the equipment, and improving the operation stability of the equipment.

[0058] The spiral protrusion 410 provided on the main shaft 400 is used to push the linkage rod 500 and the pressure plate 520 to move simultaneously in the vertical and horizontal directions. When the cover plate 920 is assembled with the bracket 300, the pressure plate 520 moves away from the bracket 300 in both the vertical and horizontal directions to avoid interference with the clamping assembly. When the assembly of the cover plate 920 and the bracket 300 is completed, the pressure plate 520 can approach the cover plate 920 simultaneously in the vertical and horizontal directions, thereby improving the assembly efficiency of the cover plate 920 and the bracket 300.
