Description

Technical Field

[0001] This invention relates to the field of PCB depaneling technology, specifically a horizontal alternating PCB depaneling machine. Background Technology

[0002] Circuit boards are essential components in electronic products. During the production process, circuit board splitting machines are used to separate circuit boards. A circuit board splitting machine is a device used to separate multiple integrated circuit boards (PCBs) into individual independent circuit boards by cutting the ribs. It can efficiently and accurately complete the circuit board splitting task. There are automated splitting machines and manual feeder splitting machines. When splitting a large integral board, the PCB is fixed by a fixed mold, and then the milling cutter automatically splits it into smaller boards. When the integral area is small and the small circuit boards are densely distributed, the splitting process is usually carried out by a circular cutter combined with manual feeding. This type of PCB is directly slit and cut. The small integral boards are manually held and pushed into the cutting groove. Under the horizontal cutting action of the circular cutter, the small circuit boards are split and fall onto the material table.

[0003] Existing sliding-blade PCB depaneling machines typically have a single lower straight blade used to work with pre-etched slots on the circuit board. During the depaneling process, operators must manually place each pre-etched slot onto the lower straight blade for further cutting. As the depaneling progresses, the operator's hand gradually approaches the circular blade, which is quite dangerous. Furthermore, the process of placing the circuit board onto the lower straight blade by hand results in poor stability and is prone to skewed cuts. When processing circuit boards in batches, operators need to align the pre-etched slots with the lower straight blade one by one before processing, which also results in low actual processing efficiency. Therefore, those skilled in the art have proposed a transverse alternating PCB depaneling machine. Summary of the Invention

[0004] The purpose of this invention is to provide a transverse alternating PCB separator to solve the problems of existing sliding blade PCB separators, such as the high risk of operators' hands gradually approaching the circular blade during PCB separation, poor processing stability, and low efficiency in batch processing where pre-cut grooves need to be aligned one by one for delivery.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a horizontal alternating PCB splitting machine, comprising:

[0012] As a further description of the above technical solution: the clamping assembly includes two sets of round rods fixedly installed on the side baffle, two sets of symmetrical clamping plates are slidably installed on the round rods, movable blocks connecting the second adjustment assembly are fixedly installed on the outer side of the two sets of clamping plates, and anti-slip pads for contacting the side of the circuit board are pasted on the inner side of the two sets of clamping plates.

[0013] As a further description of the above technical solution: the second adjustment component includes a first adjustment screw rotatably installed between the two sets of side baffles at the rear end. The side baffle at the rear end is provided with a set of round rods that slide through the clamping plate. The clamping plate and the movable block at the rear end are threadedly connected to the first adjustment screw. The movable block at the rear end is fixedly installed with a support rod that slides through the other movable blocks on the same side. The interior of the lower straight blade body is provided with a connecting groove for the support rod to move.

[0014] As a further description of the above technical solution: the first adjustment component includes a cross rod for connecting adjacent side baffles. The top connecting end of the cross rod is hinged to the side baffle, and the bottom connecting end of the cross rod is rotatably mounted with a roller that slides through the side baffle. The side baffle has an internal groove for the roller to move up and down. An auxiliary rod is fixedly mounted on the rearmost side baffle, and a second adjusting screw is rotatably mounted on it. Two sets of moving blocks that are slidably connected to the auxiliary rod are threaded onto the second adjusting screw. Both sets of moving blocks are connected to sleeves through hinged lifting rods. An adjusting rod that is fixedly connected to the two sets of sleeves is fixedly mounted on the rearmost roller.

[0015] As a further description of the above technical solution: support plates are fixedly installed on both sets of side baffles at the rear end, and an adjustment knob with one end connected to the active bevel gear is rotatably installed on both sets of support plates. A driven bevel gear that meshes with one set of active bevel gears is fixedly installed on one end of the first adjustment screw, and a driven bevel gear that meshes with the other set of active bevel gears is fixedly installed on one end of the second adjustment screw.

[0016] As a further description of the above technical solution: the elastic positioning component includes a lifting plate connected to the top of the frame plate by a first spring, a locking rod that moves through the first spring and the frame plate is fixedly installed at the bottom center of the lifting plate, and a vertical tube for the locking rod to slide into is fixedly installed at the center of the positioning ramp.

[0017] As a further description of the above technical solution: the booster assembly includes a booster rod slidably installed inside the vertical tube, a booster block connected to the bottom of the vertical tube by a second spring, the center of the booster block being fixedly connected to the bottom end of the booster rod, support rods being fixedly installed on both sides of the inner cavity of the processing box, and two sets of swing rods being rotatably installed on the surface of each set of support rods, a connecting column fixedly connected to the booster block being slidably installed inside one end of the swing rod, and a pressure rod being fixedly installed on the other end of the swing rod.

[0018] As a further description of the above technical solution: a door baffle is slidably installed on the front of the processing box, and a filter screen inclined downward toward the door baffle is fixedly installed inside the processing box.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] With the first and second adjustment components, operators can quickly adjust the spacing between multiple sets of lower straight blade supports and the tightening degree of the clamping components, enabling the equipment to quickly adapt to circuit boards of different sizes and types. This significantly improves the equipment's versatility and flexibility. When processing the same type of circuit boards in batches, only one adjustment is needed to quickly place and clamp subsequent circuit boards, greatly improving the efficiency of batch circuit board separation. The multiple sets of lower straight blade supports also help improve the stability and safety of circuit board cutting operations.

[0021] The flexible positioning components and positioning ramps ensure rapid and accurate positioning of the lower straight blade support during processing. This precise positioning mechanism not only improves cutting accuracy but also reduces errors caused by manual alignment, further enhancing the stability and consistency of the board separation process. All control terminals for the adjustment components are located on the side closest to the operator, at the rear end of the support's overall pushing and processing direction. This makes adjustment and operation more convenient for the operator, improving comfort and safety. The additional inclined filter not only filters debris generated during cutting but also concentrates the circuit boards near the door baffle, facilitating quick pickup of the boards for secondary processing or collection. This not only improves unloading efficiency but also reduces debris accumulation and environmental contamination. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-9In this embodiment of the invention, a horizontal alternating PCB splitting machine includes a worktable 10, two sets of supporting slide rails 14, and several lower straight blade supports 20, etc. The worktable 10 is connected to the PCB splitting machine body 12 located above it by vertical plates 11 arranged on both sides. The vertical plates 11 can be welded to the connecting components or detachably connected by bolts. The PCB splitting machine body 12 is provided with a cutting mechanism 13 that splits the circuit board by moving horizontally. The PCB splitting machine body 12 has a built-in mechanism for controlling the horizontal alternating movement of the cutting mechanism 13. The horizontal alternating movement of the cutting mechanism 13 can realize the PCB splitting operation. An operation panel is provided on the front for easy control, etc. The cutting mechanism 13 can be a cutting circular blade controlled by a motor to rotate, etc., which are all prior art and will not be described in detail here.

[0041] A processing box 15 is set at the center of the workbench 10. Two sets of support slide rails 14 are symmetrically installed on the top of the processing box 15. The support slide rails 14 can be directly welded to the top of the processing box 15 or can be detachably installed on the top of the processing box 15 by bolts. The lower straight blade bracket 20 is slidably installed between the two sets of support slide rails 14. The lower straight blade brackets 20 are connected by a first adjustment component 30 for controlling their spacing. Each set of lower straight blade brackets 20 has a clamping component 40 for positioning the circuit board installed on the non-cutting surface. When the cutting mechanism 13 is running, the surface of the lower straight blade bracket 20 close to the cutting mechanism 13 is the cutting surface, and the surface away from the cutting mechanism 13 is the non-cutting surface. The lower straight blade bracket 20 located at the last end of the pushing direction has a second adjustment component 50 installed on the non-cutting surface to control the synchronous displacement of the multiple sets of clamping components 40.

[0042] When using the horizontal alternating PCB separator, the operator rotates the first adjustment component 30 to adjust the spacing between the multiple sets of lower straight blade supports 20, so that the spacing of the multiple sets of lower straight blade supports 20 corresponds to the spacing of the pre-etched slots on the circuit board to be processed. The pre-etched slots and lower straight blade supports 20 are placed one-to-one to make the circuit board to be separated flat. The operator rotates the second adjustment component 50 to control the multiple sets of clamping components 40 to tighten. The multiple sets of clamping components 40 tighten the sides of the circuit to be processed. The control ends of the first adjustment component 30 and the second adjustment component 50 are both located on the side closer to the operator, that is, at the rear end of the overall support pushing processing direction, which facilitates the convenience of actual operation of the equipment. After the circuit board is fixedly placed, the multiple sets of lower straight blade supports 20 are pushed forward between the two sets of support slide rails 14. After the front lower straight blade support 20 is moved to the cutting position, the PCB separator is separated by the PCB separator body 12 and the cutting mechanism 13. After a single pre-etched slot is cut, the multiple sets of lower straight blade supports 20 are pushed forward to cut the subsequent pre-etched slots one by one.

[0043] After all the pre-etched grooves in a single direction on the circuit board are divided, pull the multiple sets of lower straight blade supports 20 backward, rotate the second adjustment component 50 to control the multiple sets of clamping components 40 to expand outward, so that the cut circuit board can be unloaded. The slit circuit board can fall into the processing box 15 for collection through the gap between two adjacent sets of lower straight blade supports 20. When cutting a batch of circuit boards of the same type, it is only necessary to use the first adjustment component 30 to adjust the distance between the multiple sets of lower straight blade supports 20 once. Subsequently, the circuit board to be processed can be directly aligned with the lower straight blade supports 20 and quickly placed and clamped, which can effectively improve the processing efficiency of the circuit board, and also improve the stability and safety of the circuit board cutting operation.

[0044] Furthermore, the transverse alternating PCB separator also includes an elastic positioning component 60. Each set of lower straight blade supports 20 has an elastic positioning component 60 on both sides. The top of the processing box 15 has a positioning ramp 16 on both sides for slidingly embedding a single elastic positioning component 60. The positioning ramp 16 is used to position the lower straight blade support 20 connected to the elastic positioning component 60 embedded therein to the cutting station. The processing box 15 has a booster component 70 for lifting the elastic positioning component 60 in the positioning ramp 16.

[0045] When the operator pushes the lower straight blade bracket 20 between the two sets of support slide rails 14, the lower straight blade bracket 20 can also move the elastic positioning components 60 on both sides. When the elastic positioning components 60 move and snap into the inside of the positioning ramp 16, the lower straight blade bracket 20 connected to the above-mentioned elastic positioning components 60 is precisely positioned at the cutting processing line. This makes it convenient for the equipment to automatically align the pre-cut groove of the circuit board to be cut with the cutting mechanism 13 during use, which can further improve the convenience and accuracy of the device operation. After the cutting of a single pre-cut groove is completed, the operator can use the pusher component 70 to lift the elastic positioning component 60 inside the positioning ramp 16 to the top, so that the operator can continue to push the lower straight blade bracket 20 forward to make the next set of elastic positioning components 60 and the lower straight blade bracket 20 automatically position and process.

[0046] In one embodiment, see Figures 1-9 Specifically, the lower straight blade support 20 includes a lower straight blade body 201 for aligning with pre-etched grooves on the circuit board. When the cutting mechanism 13 performs a cutting operation, the surface of the lower straight blade body 201 that is close to the cutting mechanism 13 is the cutting surface. Two sets of side baffles 202 for supporting the clamping assembly 40 and the first adjusting assembly 30 are fixedly installed on the non-cutting surface of the lower straight blade body 201. A slider 203 that is slidably connected to the supporting slide rail 14 and a frame plate 204 for supporting the elastic positioning assembly 60 are fixedly installed on the outer side of the side baffle 202. The fixed connection points of the components can be directly welded.

[0047] Correspondingly, the clamping assembly 40 includes two sets of round rods 401 fixedly installed on the side baffle 202. Two sets of symmetrical clamping plates 402 are slidably installed on the round rods 401. Movable blocks 403 connecting the second adjusting assembly 50 are fixedly installed on the outer sides of the two sets of clamping plates 402. Anti-slip pads 404 for contacting the sides of the circuit board are pasted on the inner sides of the two sets of clamping plates 402. The two sets of clamping plates 402 that slide relative to each other on the round rods 401 can clamp the two sides of the circuit board to be processed, which facilitates the circuit board to provide stable limiting support during the cutting process. The inner side of the clamping plate 402 abuts against the side of the circuit board through the anti-slip pads 404. The anti-slip pads 404 can be made of materials such as rubber or sponge, which can improve the stability of the clamping plate 402 in fixing the side of the circuit board and also provide a certain degree of protection for the circuit board.

[0048] The second adjustment assembly 50 includes a first adjustment screw 501 rotatably mounted between the two sets of side baffles 202 at the rear end. A set of round rods 401 that slide through the clamping plate 402 are provided on the rearmost side baffle 202. The clamping plate 402 and the movable block 403 at the rear end are threadedly connected to the first adjustment screw 501. A support rod 502 that slides through the other movable blocks 403 on the same side is fixedly mounted on the movable block 403 at the rear end. A connecting groove 17 for the support rod 502 to move is provided inside the lower straight blade body 201. The operator rotates the first adjustment screw 501... The screw 501 and the first adjusting screw 501 are threadedly connected to the two sets of clamping plates 402 and the movable block 403 through two sets of symmetrical threaded grooves. When the first adjusting screw 501 controls the relative or reverse movement of the two sets of clamping plates 402 and the movable block 403 connected to it, the movable block 403 can drive the other movable blocks 403 and clamping plates 402 on the same side to move together through the support rod 502. The support rod 502 is lower than the top of the lower straight blade body 201 and is located outside the two sets of clamping plates 402. It will not affect the normal operation of the cutting mechanism 13 or the unloading of the circuit board after cutting.

[0049] In one embodiment, see Figures 1-9 Specifically, the first adjustment component 30 includes a cross rod 301 for connecting adjacent side baffles 202. The top connecting end of the cross rod 301 is hinged to the side baffle 202. The bottom connecting end of the cross rod 301 is rotatably mounted with a roller 302 that slides through the side baffle 202. The side baffle 202 has an active groove 18 for the roller 302 to move up and down. An auxiliary rod 303 is fixedly mounted on the last side baffle 202 and a second adjustment screw 304 is rotatably mounted on it. Two sets of moving blocks 305 that are slidably connected to the auxiliary rod 303 are threaded onto the second adjustment screw 304. Both sets of moving blocks 305 are connected to sleeves 306 through hinged lifting rods 308. An adjustment rod 307 that is fixedly connected to the two sets of sleeves 306 is fixedly mounted on the last roller 302.

[0050] The operator rotates the second adjusting screw 304, which drives two sets of moving blocks 305 to slide on the auxiliary rod 303 through two sets of symmetrical threaded grooves. The moving blocks 305 can drive the sleeve 306 and the adjusting rod 307 fixedly installed in the center to move up and down through the lifting rod 308. The adjusting rod 307 can drive multiple sets of connected cross rods 301 to extend and retract synchronously through the rollers 302 connected at both ends. Each set of cross rods 301 consists of two rods that cross at the middle point and rotate together to form an "X" shaped structure. The two ends of each rod are connected to the adjacent set of cross rods 301, thus forming a continuous grid-like telescopic structure. The rotation of the cross rods 301 can adjust the spacing between multiple sets of lower straight knife supports 20. The side baffles 202 of the lower straight knife support 20 can also drive the movable block 403 to slide on the support rod 502 to ensure stable adjustment of the spacing between components.

[0051] Furthermore, support plates 19 are fixedly installed on both sets of side baffles 202 at the rear end. An adjustment knob 111 with one end connected to the driving bevel gear 110 is rotatably installed on each set of support plates 19. The driving bevel gear 110 is welded to the end of the adjustment knob 111. A driven bevel gear 112 that meshes with one set of driving bevel gears 110 is fixedly installed on one end of the first adjustment screw 501. A driven bevel gear 112 that meshes with another set of driving bevel gears 110 is fixedly installed on one end of the second adjustment screw 304. When the operator rotates the adjustment knob 111, the adjustment knob 111 drives the driving bevel gear 110 to rotate. The driving bevel gear 110 drives the driven bevel gear 112 that meshes with it to rotate. The driven bevel gear 112 drives the adjustment screw connected to it to rotate. This can effectively improve the convenience of the operator in controlling the rotation of the adjustment screw.

[0052] In one embodiment, see Figures 1-9 Specifically, the elastic positioning component 60 includes a lifting plate 602 connected to the top of the frame plate 204 via a first spring 601. The ends of the springs and their connecting components can be fixedly connected. A locking rod 603 is fixedly installed at the bottom center of the lifting plate 602, which movably passes through the first spring 601 and the frame plate 204. A vertical tube 113 for the locking rod 603 to slide into is fixedly installed at the center of the positioning ramp 16. When the locking rod 603 of the elastic positioning component 60 moves to abut against the positioning ramp 16, as the lower straight knife bracket 20 continues to push forward, the locking rod 603 can automatically move upward with the positioning ramp 16. The moving locking rod 603 can drive the lifting plate 602 to move and the first spring 601 to extend and retract. When the locking rod 603 moves to the top of the vertical tube 113, it can be automatically locked into the vertical tube 113 by the automatic reset of the first spring 601, thereby realizing the automatic positioning of the elastic positioning component 60 and the lower straight knife bracket 20 connected to it.

[0053] In detail, the booster assembly 70 includes a booster rod 701 slidably installed inside the vertical tube 113. The bottom of the vertical tube 113 is connected to a booster block 703 via a second spring 702. The center of the booster block 703 is fixedly connected to the bottom end of the booster rod 701. Support rods 704 are fixedly installed on both sides of the inner cavity of the processing box 15. Two sets of swing rods 705 are rotatably installed on the surface of each set of support rods 704. A connecting column 706 fixedly connected to the booster block 703 is slidably installed inside one end of the swing rod 705. A pressure rod 707 is fixedly installed on the other end of the swing rod 705.

[0054] When it is necessary to remove the elastic positioning component 60 that is snapped into the vertical tube 113, the operator can press down the nearby pressure rod 707. The pressure rod 707 can drive the swing rod 705 to rotate around the support rod 704. The end of the support rod 704 can drive the push block 703 and the push rod 701 to move upward through the connecting column 706. The end of the support rod 704 is provided with a limiting groove for the connecting column 706 to move. The push rod 701, which moves upward inside the vertical tube 113, can lift the locking rod 603 inside the vertical tube 113. The movement of the push block 703 can drive the second spring 702 to extend and retract. The reset of the second spring 702 can automatically reset the push block 703, push rod 701 and swing rod 705 after use for the next operation.

[0055] A door baffle 114 is slidably installed on the front of the processing box 15. A filter screen 115 inclined downward toward the door baffle 114 is fixedly installed inside the processing box 15. The processed circuit board can fall down onto the filter screen 115. The filter screen 115 can filter the debris generated during cutting and also facilitates the concentration of the circuit board near the door baffle 114. When the circuit board is processed into separate boards, it is usually necessary to cut the pre-cut grooves in both directions. The circuit board after a single processing is concentrated near the door baffle 114, which makes it convenient for the staff to pick up the circuit board for secondary processing. The operator can pull up the door baffle 114 to open the front of the processing box 15, which also facilitates quick material collection.
