Description

Technical Field

[0001] This invention relates to the field of PCBA board separation technology, specifically to a PCBA board separation device and separation method. Background Technology

[0002] In the electronics manufacturing industry, in order to improve the production efficiency of PCBA boards (printed circuit boards that have already been assembled with components), multiple small boards are set on a large board for production during the PCBA board production process. After production, the large board usually needs to be divided into multiple small boards.

[0003] Existing board separation technologies mainly include manual board breaking, laser cutting, and stamping board separation. Manual board breaking is inefficient and has poor precision, which can easily lead to damage to the edges of PCBA boards; laser cutting equipment is expensive, and the high temperature generated during the cutting process can easily damage the components on the board; most traditional board separation devices can only complete a single separation, and for a large number of small boards on a large board, they cannot achieve integrated processing from the whole board to the small boards, resulting in low board separation efficiency and difficulty in meeting the needs of large-scale production. Summary of the Invention

[0004] The purpose of this invention is to provide a PCBA board splitting device and method.

A transplanting unit is provided on one side of the first and second partition boards, which can move the half-board from the first partition board to the second partition board.

[0006] In some embodiments, the first partition unit includes a first fixing seat, which is disposed on one side of the second partition unit; A plate-breaking structure is provided on the first fixed base, and the PCBA board is provided on the plate-breaking structure; A lifting assembly, which is connected to the first fixed base and is disposed above the folding plate structure; A stop assembly is provided at the bottom of the lifting assembly and pressed against the PCBA board; A lifting assembly, which is mounted on the first fixed base, can lift the half plate on the folding plate structure; A sensing component is disposed between the first fixed base and the folding plate structure.

[0007] In some embodiments, the plate-breaking structure includes two rotating blocks, which are hinged to the first fixed seat on one side close to each other and are symmetrically arranged on both sides of the stop assembly. The top of the two rotating blocks is provided with a placement groove, and the PCBA board is placed in the placement groove. The ejector slot extends through the rotating block, and the lifting assembly is located below the ejector slot. Two upper lever cylinders are respectively located at the middle of one side away from the other side of the two rotating blocks, and the bottom of the upper lever cylinder is hinged to the first fixed seat. The output shaft of the upper lever cylinder is hinged to the rotating block.

[0008] In some embodiments, the stop assembly includes a stop block disposed at the bottom of the lifting assembly; A centering pressure plate is provided at the bottom of the stop block, and the central axis of the centering pressure plate and the central axis of the PCBA board are located on the same vertical plane. Two side pressure plates are symmetrically arranged on both sides of the centering pressure plate, and the side pressure plates can slide along the height direction at the bottom of the stop block. A spring is provided between the top of the side pressure plate and the stop block.

[0009] In some embodiments, the lifting assembly includes two lifting cylinders, which are located at the bottom of the folding plate structure; A lifting plate is located at the bottom of the ejection slot and is fixedly connected to the output shaft of the lifting cylinder.

[0010] In some embodiments, the sensing component includes four sensing slots, which are symmetrically arranged on both sides of the first fixing base; Four L-shaped blocks are symmetrically arranged on both sides of the folding plate structure; The first sensor is disposed on the bottom wall of the sensing groove; The second sensor is located on the top wall of the sensing slot and is offset from the first sensor.

[0011] In some embodiments, the second partition unit includes a second fixing seat, which is disposed on one side of the first partition unit; The drive assembly is disposed on the top of the second fixing base; Two stamped parts are symmetrically arranged at the bottom of the drive assembly; Three fixed vertical plates are evenly spaced at the bottom of the second fixed base; Two pressure-bearing components are provided, each with a half plate. The pressure-bearing components are located below the stamping component and between two adjacent fixed vertical plates. The pressure-bearing components can reciprocate in the height direction.

[0012] In some embodiments, the fixed vertical plate has deburring textures on both sides.

[0013] In some embodiments, the transplanting unit includes a transplanting cylinder, which is disposed at one end of the first dividing plate unit; A transplanting frame, which is connected to the transplanting cylinder and can slide between the first dividing plate unit and the second dividing plate unit; Two limiting seats are symmetrically arranged at one end of the transplanting cylinder near the first dividing plate unit; A sliding rod is disposed between the two limiting seats and passes through the transplanter frame; An avoidance cylinder is located at the top of the transplanter near the first partition unit. A clamping element is connected to the output shaft of the avoidance cylinder.

[0014] A method for stamping and separating PCBA boards includes the following steps: Step S1: The PCBA board is placed on the splitting structure. The lifting component drives the stop component to descend, pressing it against the PCBA board. The splitting structure splits the PCBA board into two symmetrical halves. Step S2: The lifting assembly drives the stop assembly to rise, the transplanting unit moves above the two half-plates, the lifting assembly starts to lift the two half-plates, the transplanting unit clamps the two half-plates, and the lifting assembly resets. Step S3: The transplanting unit moves the two half-plates onto the pressure-bearing component, and the transplanting unit moves away from the second plate-splitting unit; Step S4: The drive assembly drives the two stamping parts to descend and press them onto the two half plates respectively. The half plates transmit the force to the bearing member, causing the bearing member to move downward. The two sides of the half plate separate under the misalignment impact of the stamping parts and the fixed vertical plate, dividing the half plate into multiple small plates. Step S5: During the descent, the small board will rub against the side of the fixed vertical plate to remove burrs from the small board. The driving component drives the two stamping parts to rise and reset, and the pressure bearing parts reset, thereby realizing the separation of the PCBA board.

[0015] The above-described technical solutions in the embodiments of the present invention have at least the following technical effects or advantages: The first board-splitting unit of this invention utilizes the principle of "symmetrical breaking" to precisely divide the entire board into two half boards through the symmetrical rotation of the rotating block. The second board-splitting unit 2 adopts the principle of "stamping + staggered division" to separate the two sides of the half board, dividing the half board into multiple small boards. Through the transfer mechanism, the half board is transferred from the first board-splitting unit to the second board-splitting unit, realizing the integrated processing of PCBA board from the whole board to the small board, breaking through the limitation of single division of traditional equipment, thereby improving the board-splitting efficiency.

[0016] This invention automatically removes edge burrs during the descent of the small plate by setting deburring textures on the side of the fixed vertical plate, eliminating the need for an additional deburring process and reducing production costs and cycle time.

[0017] The centering plate and side plate of the stop assembly of the present invention work together to ensure that the PCBA board does not shift during the separation process, while avoiding the influence of the side plate pressing on the separation process and ensuring the integrity of the second half of the board after separation.

[0025] refer to Figure 1-8 A PCBA board splitting device includes a first splitting unit 1, a second splitting unit 2, and a transfer unit 3. The first splitting unit 1 can split the PCBA board into two half boards. The second splitting unit 2 is located on one side of the first splitting unit 1 and can split the half board into multiple smaller boards. The transfer unit 3 is located on one side of the first splitting unit 1 and the second splitting unit 2 and can move the half board from the first splitting unit 1 to the second splitting unit 2. Through the two-stage splitting process of the first splitting unit 1 and the second splitting unit 2 and the transfer by the transfer unit 3, continuous splitting operation of the PCBA board can be realized, thereby realizing the continuous division of the PCBA board from a whole board to smaller boards and improving the splitting efficiency.

[0026] In some embodiments, the first board-separating unit 1 includes a first fixed base 11, a board-breaking structure 12, a lifting assembly 13, a stop assembly 14, a lifting assembly 15, and a sensing assembly 16. The first fixed base 11 is located on one side of the second board-separating unit 2 and serves as the mounting base for the first board-separating unit 1. Its specific shape can be set according to actual conditions. The board-breaking structure 12 is located on the first fixed base 11 and has a PCBA board on it. The PCBA board can be placed on the board and the initial board separation can be completed. The lifting assembly 13 is connected to the first fixed base 11 and is located above the board-breaking structure 12. The lifting assembly 13 can drive the stop assembly 14 to rise and fall. 13 can be a lifting cylinder, which is fixedly connected to the stop assembly 14. The lifting cylinder and the stop assembly 14 can be provided with multiple guide rods to improve the stability of the stop assembly 14 during the lifting process. The stop assembly 14 is located at the bottom of the lifting assembly 13 and presses against the PCBA board when it descends to prevent the PCBA board from shifting during the separation process. This ensures that the PCBA board is accurately positioned during the separation process, thereby improving the separation accuracy. The lifting assembly 15 is located on the first fixed seat 11 and can lift the half board on the board-breaking structure 12 to facilitate the grabbing of the subsequent half board. The sensing assembly 16 is located between the first fixed seat 11 and the board-breaking structure 12 and can detect the working status of the board-breaking structure 12 to ensure the normal operation of the board separation process.

[0027] In some embodiments, the prying structure 12 includes two rotating blocks 121, an ejection groove 122, and two upper prying cylinders 123. The two rotating blocks 121 are hinged to the first fixed base 11 on opposite sides and can be axially connected via a fixed shaft, allowing the two rotating blocks 121 to rotate on the first fixed base 11. The two rotating blocks 121 are symmetrically arranged on both sides of the stop assembly 14. The top of each rotating block 121 has a placement groove containing a PCBA board for stable placement. The ejection groove 122 penetrates the rotating block 121 and can be slightly... The placement slot prevents the PCBA board from falling from the ejection slot 122, ensuring stable placement. A lifting assembly 15 is located below the ejection slot 122, providing a lifting channel for the lifting plate to eject the half-board, facilitating subsequent gripping. Two upper-bending cylinders 123 are positioned on opposite sides of the two rotating blocks 121, with their bottoms hinged to the first fixed seat 11. A shaft connection allows the upper-bending cylinders 123 to rotate on the first fixed seat 11. The output shaft of the upper-bending cylinders 123 is hinged to the rotating block 121. The extension and retraction of the upper-bending cylinders 123 causes the rotating block 121 to rotate around the hinge point, and the pressing action of the stop assembly 14 utilizes the brittleness of the PCBA board to break it into two symmetrical half-boards, achieving the initial separation of the PCBA board.

[0028] In some embodiments, the stop assembly 14 includes a stop block 141, a centering pressure plate 142, and two side pressure plates 143. The stop block 141 is located at the bottom of the lifting assembly 13 and serves as the mounting carrier for the centering pressure plate 142 and the side pressure plates 143. The centering pressure plate 142 is located at the bottom of the stop block 141, and the central axis of the centering pressure plate 142 is located on the same vertical plane as the central axis of the PCBA board, ensuring symmetrical force on the PCBA board during pressing. The cross-section of the centering pressure plate 142 can be an isosceles triangle with the sharp corner pointing downwards, which ensures the pressing effect on the PCBA board while reducing the contact area with the PCBA board, increasing the pressure applied to the PCBA board, improving the instantaneous speed of PCBA board separation, and reducing damage to the PCBA board during separation. The two side pressure plates 143 are symmetrically arranged on both sides of the centering pressure plate 142, and the side pressure plates 143 can slide along the height direction at the bottom of the stop block 141. A spring is provided between the top of the side pressure plate 143 and the stop block 141.

[0029] When the stop assembly 14 descends, the centering pressure plate 142 first contacts the center of the PCBA board, and the side pressure plate 143 adaptively presses the edge of the PCBA board under the action of the spring, achieving all-round fixation and thus improving the pressing effect on the PCBA board. When the upper prying cylinder 123 drives the rotating block 121 to rotate, causing the two sides of the PCBA board to tilt upward, the side pressure plate 143 is subjected to the force of the PCBA board and will slide on the stop block 141, partially retracting into the stop block 141. This prevents the side pressure plate 143 from pressing against the center side of the PCBA board during board separation, which would affect the board separation and thus damage the PCBA board.

[0030] In some embodiments, the lifting assembly 15 includes two lifting cylinders 151 and a lifting plate 152. The two lifting cylinders 151 are located at the bottom of the splitting structure 12 and provide lifting power. The lifting plate 152 is located at the bottom of the ejection slot 122 and is fixedly connected to the output shaft of the lifting cylinders 151. When the PCBA board is split into half, the lifting cylinders 151 drive the lifting plate 152 to rise, pass through the ejection slot 122, and lift the half board away from the rotating block 121, facilitating subsequent gripping by the transfer unit 3. In some embodiments, the sensing component 16 includes four sensing slots 161, four L-shaped blocks 162, a first sensor 163, and a second sensor 164. The four sensing slots 161 are symmetrically arranged on both sides of the first fixed base 11, and the four L-shaped blocks 162 are symmetrically arranged on both sides of the swivel structure 12, which can rotate synchronously with the rotating block 121. The first sensor 163 is located on the bottom wall of the sensing slot 161, and the second sensor 164 is located on the top wall of the sensing slot 161 and is offset from the first sensor 163.

[0031] When the rotating block 121 rotates, the L-shaped block 162 rotates within the sensing groove 161. By triggering the first sensor 163 or the second sensor 164, the opening and closing angle of the rotating block 121 is determined based on the sensing signal fed back by the first sensor 163 or the second sensor 164, ensuring that the separation action is in place and avoiding excessive rotation of the rotating block 121.

[0032] In some embodiments, the second plate-splitting unit 2 includes a second fixed base 21, a drive assembly 22, two stamping parts 23, three fixed vertical plates 24, and two pressure-bearing parts 25. The second fixed base 21 is located on one side of the first plate-splitting unit 1 and serves as the mounting base for the second plate-splitting unit 2. It provides mounting positions and stable support for other components. The second fixed base 21 can be made of high-strength alloy steel, capable of withstanding the large load generated by the mold during operation and providing stable support for the entire mold. The shape of the second fixed base 21 can be designed according to actual needs. The drive assembly 22 is located on the top of the second fixed base 21 and provides stamping power to drive the stamping parts 23 to perform stamping actions. The two stamping parts 23 are symmetrically arranged at the bottom of the drive assembly 22. The drive assembly 22 may include a cylinder, a lifting platform, a limit rod, and a limit... The positioning sleeve, through the cooperation of the limiting rod and the limiting sleeve, ensures the stability of the lifting platform during its up and down movement, prevents it from deviating, and thus improves the stamping accuracy. Three fixed vertical plates 24 are equally spaced at the bottom of the second fixed seat 21, serving as positioning and deburring structures during plate separation. Fixed baffles can be provided between the three fixed vertical plates 24, which can be fixed with bolts to improve the connection strength between the three fixed vertical plates 24 and the second fixed seat 21, thereby improving the impact resistance of the fixed vertical plates 24. Half plates are placed on the two pressure members 25, which are correspondingly located below the stamping part 23 and between two adjacent fixed vertical plates 24. The bottom of the pressure member 25 can be provided with a spring or other reset structure so that the pressure member 25 can reciprocate in the height direction, facilitating the gripping of the small plates after the half plate is divided into multiple small plates.

[0033] When the drive assembly 22 lowers the stamping part 23, the pressure-bearing part 25 moves downward under pressure. Under the coordinated action of the stamping part 23 and the fixed vertical plate 24, the long sides of the half plate are separated, thus dividing the half plate into multiple smaller plates. The distance between the fixed vertical plate 24 and the pressure-bearing part 25 can be set according to parameters such as the width of the long side to be separated of the plate to be stamped, to ensure the smooth separation of the plate to be stamped.

[0034] In some embodiments, both sides of the fixed vertical plate 24 are provided with deburring textures (such as fine diagonal lines). When the small plate descends after the separation, its edge rubs against the textures of the fixed vertical plate 24, which can remove the burrs generated during the separation, eliminating the need for a separate deburring process.

[0035] In some embodiments, the stamping part 23 may be a channel plate, which can be pressed onto the half plate by the two sides of the channel plate and a clearance space is formed between the two sides. This allows the stamping part 23 to fix the plate to be stamped when it cooperates with the bearing part 25, while avoiding contact between the stamping part 23 and the components on the plate to be stamped, thereby protecting the components on the half plate.

[0036] In some embodiments, the transplanting unit 3 includes a transplanting cylinder 31, a transplanting frame 32, two limiting seats 33, a sliding rod 34, an avoidance cylinder 35, and a clamping member 36. The transplanting cylinder 31 is located at one end of the first partition unit 1 and can provide horizontal movement power. The transplanting frame 32 is connected to the transplanting cylinder 31. The transplanting cylinder 31 can be a rodless cylinder. The transplanting frame 32 can be fixedly connected to the slider on the rodless cylinder. The sliding of the slider provides the movement power for the transplanting frame 32. The transplanting frame 32 can slide between the first partition unit 1 and the second partition unit 2 along the sliding rod 34 under the drive of the transplanting cylinder 31. The two limiting seats 35 and the two limiting seats 36... The seats 33 are symmetrically arranged at one end of the transplanting cylinder 31 near the first dividing plate unit 1. The slide rod 34 is located between the two limiting seats 33 and passes through the transplanting frame 32. It can provide guidance for the transplanting frame 32 and cooperate with the avoidance cylinder 35 to improve the stability of the sliding of the transplanting frame 32. The avoidance cylinder 35 is located at the top of the transplanting frame 32 near the first dividing plate unit 1. It can drive the clamping member 36 to rise and fall, adjust the height of the clamping member 36, and avoid interference during gripping. The clamping member 36 is connected to the output shaft of the avoidance cylinder 35. It can adopt a pneumatic gripper structure and be connected to an external air source to realize the clamping of the half plate.

[0037] In some embodiments, a control system is also included. The control system is electrically connected to the first separating unit 1, the second separating unit 2, and the transplanting unit 3. Through the control system, the first separating unit 1, the second separating unit 2, and the transplanting unit 3 can be automatically controlled, thereby shortening the time interval between different actions and further improving the separating efficiency.

[0038] A method for stamping and separating PCBA boards includes the following steps: Step S1: Place the PCBA board in the placement slot of the board-breaking structure 12. The lifting component 13 drives the stop component 14 to descend. The stop block 141 drives the centering pressure plate 142 and the side pressure plate 143 to move downward. The centering pressure plate 142 first contacts the PCBA board and inserts into the partition groove in the middle of the PCBA board, so that the central axis of the centering pressure plate 142 and the central axis of the PCBA board are on the same vertical plane, thereby ensuring uniform pressing of the PCBA board. At the same time, the side pressure plate 143 presses the two sides of the center of the PCBA board under the action of the spring, forming multi-directional pressing, improving the pressing effect, and ensuring that the PCBA board will not move during the board-breaking process. When the upper prying cylinder 123 is activated, both upper prying cylinders 123 extend and retract respectively, driving the two rotating blocks 121 to rotate to both sides around the hinge point with the first fixed seat 11. Due to the symmetrical arrangement of the two rotating blocks 121 and the PCBA board being pressed by the stop assembly 14, the PCBA board is broken into two symmetrical halves under the action of the rotating blocks 121, taking advantage of the inherent brittleness of the PCBA board. During this process, the sensing assembly 16, through the cooperation of the L-shaped block 162 with the first sensor 163 and the second sensor 164, senses the position status of the board breaking structure 12 and the PCBA board in real time. When the board breaking structure 12 completes the board breaking action, the position of the L-shaped block 162 changes. The first sensor 163 and the second sensor 164 sense the position signal of the L-shaped block 162 and transmit the signal to the control system. The control system determines that the board breaking is complete.

[0039] Step S2: The lifting assembly 13 drives the stop assembly 14 to rise, the transplanting cylinder 31 is activated, and the transplanting frame 32 is driven to move towards the first dividing plate unit 1 under the guidance of the slide rod 34 until the transplanting frame 32 moves directly above the two half-plates. The avoidance cylinder 35 is activated, driving the clamping member 36 to descend to a suitable position so that it can clamp the half-plate. The lifting cylinder 151 is activated, driving the lifting plate 152 to rise, and pushing the half-plate away from the rotating block 121 through the ejection groove 122, so that the half-plate is separated from the dividing plate structure 12. The clamping member 36 closes to clamp the lifted half-plate, and the lifting cylinder 151 retracts to reset the lifting plate to the initial position. During this process, the two lifting cylinders 151 can be activated sequentially, which can reduce interference when operating simultaneously and improve the coordination of work.

[0040] Step S3: The transplanting cylinder 31 is restarted. The transplanting cylinder 31 drives the transplanting frame 32 to move the clamping member 36 holding the half plate towards the second dividing plate unit 2 until the half plate moves above the pressure member 25 of the second dividing plate unit 2. The avoidance cylinder 35 drives the clamping member 36 to descend to the corresponding height, release the half plate, and the half plate falls on the pressure member 25 under the action of gravity, completing the transplanting operation of the half plate. The transplanting unit 3 is reset and moves away from the second dividing plate unit 2.

[0041] Step S4: The drive assembly 22 is activated, causing the two stamping parts 23 to descend and press against the two half-plates respectively. After the half-plates are subjected to the force of the stamping parts 23, they transmit the force to the bearing parts 25, which move downwards under pressure. Since the fixed vertical plates 24 are evenly spaced at the bottom of the second fixed seat 21, and the stamping parts 23 and the fixed vertical plates 24 are misaligned, during the downward movement of the half-plates, the two sides of the half-plates are misaligned and impacted by the pressure of the stamping parts 23 and the obstruction of the fixed vertical plates 24. The two sides of the half-plates separate along the preset dividing lines, thus dividing the half-plates into multiple small plates.

[0042] Step S5: The small board continues to descend under its own weight and the pressure-bearing component 25. During the descent, it rubs against the deburring texture on the side of the fixed vertical plate 24 to remove edge burrs. The drive component 22 drives the two stamping components 23 to rise and reset. The pressure-bearing component 25 rises and resets under the action of the bottom reset structure, waiting for the next board separation operation, completing the entire PCBA board separation process, and can be transferred to the next process by a robotic arm or other transfer structure. The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
