Description

Technical Field

[0001] The present invention relates to the technical field of PCB board cutting, and in particular to a PCB substrate cutting device with a waste residue cleaning function. Background Art

[0002] The first step in PCB production is cutting. The process of cutting is to put a large-sized substrate into the cutting and cutting equipment to cut it into smaller, easier-to-process sizes. The cutting method for the substrate is generally completed by guillotine punching. During the movement of the substrate in a fixed direction, the guillotine falls from above to punch and cut the substrate. This method is simple and fast, and the work efficiency is extremely high. However, this cutting method still has some defects in use. The main one is that during the punching process of the guillotine, when the blade cuts into the substrate, fine and sharp waste residues will be generated. Some of the waste residues adhere to the blade, and some of the waste residues fall on the pad under the guillotine. Therefore, the subsequent substrate will be scratched by these sharp waste residues during the movement, forming scratches that cannot be easily detected by the naked eye. These scratches will affect the subsequent processing links. Summary of the invention

[0014] The present invention brings at least the following effects:

[0015] 1. The present invention provides a lifting pad under the cutter. When the material needs to be cut, the pad is lifted, and when the cutting is completed, the pad is lowered. In this way, the material will not contact the pad during the movement. Therefore, the lifting of the pad can prevent the sharp waste residue adhering to the pad from scratching the material. The inclined scrapers on both sides of the cutter scrape the cutter and then scrape off the waste residue adhering to the blade in the process of following the movement of the cutter, so as to clean the waste residue on the blade part. The brush block movably arranged above the pad can scrape the blade surface of the pad and the cutter at the same time, and further clean the adhering waste residue to the side of the pad.

[0016] 2. The friction belt set at the bottom of the pad can be used to grind the edges of the cut materials to eliminate the protruding burrs formed at the fracture to avoid scratches between the materials.

[0017] 3. The adhesion roller and the slag collecting box of the present invention can remove the residual waste slag on the surface of the pad while following the movement of the brush block, and the waste slag adhered to the adhesion roller can be scraped off and collected through the curved edge of the slag collecting box.

[0018] 4. The pressing block provided in the present invention can first contact the material when the cutter moves down, thereby fixing the material on the pad first, avoiding deviation in the cutting process and causing skew in the cutting size.

[0019] 5. By connecting the movable rod of the second electric push block to the push plate through a movable connection, it can be avoided that the movable rod is subjected to external force during operation and the rod body is bent, resulting in failure to retract normally.

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be appreciated that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some but not all structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without making creative work are within the scope of protection of the present application.

[0041] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] The present invention specifically discloses a PCB substrate cutting device with a waste residue cleaning function, such as Figure 1-Figure 9 As shown, it includes: a bed 1, on which a feeding and conveying mechanism is provided to enable the substrate to move laterally on the bed 1. Figure 1 As shown, the feeding conveying mechanism includes: a first conveyor belt 21 and a second conveyor belt 22 installed side by side on the left side of the bed 1. The first conveyor belt 21 and the second conveyor belt 22 have opposite conveying directions during operation, the first conveyor belt 21 conveys to the left, and the second conveyor belt 22 conveys to the right. A transmission roller 3 is arranged and installed on the right side of the bed 1. The transmission roller 3 is driven by a first driving motor 31 installed on its side. A crossbeam 4 is set between the first conveyor belt 21 and the transmission roller 3. A cutting mechanism for cutting substrates is set on the crossbeam 4. A pushing device is set on the bed 1 to push the materials on the first conveyor belt 21 and the second conveyor belt 22.

[0043] Among them, the purpose of arranging the first conveyor belt 21 and the second conveyor belt 22 with relative conveying directions is that: when cutting the substrate, it is necessary to ensure that the size of each cut is consistent. Therefore, in order to avoid the position of the substrate not matching the cutting area after the conveyor belt stops conveying, resulting in cutting errors, it is necessary to use a pushing device to cooperate with the second conveyor belt 22 to push the substrate forward while maintaining an opposite backward pushing force on the substrate, so as to ensure that each cutting of the substrate is accurate.

[0044] Specifically, the substrate falls on the second conveyor belt 22 and begins to be transported, and at the same time, the pushing device presses against the substrate from the end of the substrate and pushes it forward. After the substrate enters the area of ​​the first conveyor belt 21 from the second conveyor belt 22, the substrate will be pushed backward by the output of the first conveyor belt 21, but under the push of the pushing device, the substrate moves steadily toward the cutting area, and the cutting area cuts the substrate after reaching the designated position.

[0045] according to Figure 2-Figure 4 As shown, the cutting mechanism arranged on the crossbeam 4 includes: a plurality of first hydraulic cylinders 41 are fixedly installed at even intervals, the movable parts of the plurality of first hydraulic cylinders 41 are commonly fixedly connected to a same mounting plate 42, the mounting plate 42 moves up and down under the action of the plurality of first hydraulic cylinders 41, a cutter 5 is fixedly connected to the bottom of the mounting plate 42, a plurality of oblique sliding reset members 51 are fixedly installed on both sides of the cutter 5, the plurality of oblique sliding reset members 51 on the same side are commonly connected to a same scraper 52, the scraper 52 is inclined against the blade of the cutter 5 under the inclined guidance of the oblique sliding reset member 51; through the sliding friction of the scraper 52 on the blade, the waste residue attached to the blade will fall off through the friction of the scraper 52.

[0046] according to Figure 4 As shown, a protrusion 53 extending vertically downward is also provided at the bottom of the scraper 52. The main function of the protrusion 53 is that before the cutter 5 moves down and abuts against the substrate, the protrusion 53 first abuts against the surface of the substrate and pushes the scraper 52 in advance, giving the scraper 52 a sufficiently long sliding distance, so that the blade of the cutter 5 can be better scraped.

[0047] Among them, according to Figure 5 and Figure 6 As shown, the oblique sliding reset member 51 includes: an oblique block 511, on which a guide rod 512 is symmetrically fixed, the oblique block 511 is installed on the cutter 5 by bolts, a sliding groove is opened on the oblique block 511, a sliding plate 514 is slidably arranged on the oblique block 511 through the sliding groove, and is slidably connected to the guide rod 512, a first spring 513 is sleeved on the guide rod 512, a cover plate 515 is fixedly installed on the oblique block 511, and the first spring 513 is pressed against the sliding plate 514 through the provided cover plate 515, and the scraper 52 is installed on the sliding plate 514.

[0048] Specifically, after the scraper 52 rests against the blade of the cutter 5, the scraper 52 is pushed upward from the bottom and slides upward in the inclined direction of the inclined block 511, and the first spring 513 is deformed during the movement. After the scraper 52 loses the external force, it returns to its original position through the first spring 513.

[0049] according to Figure 3 and Figure 7 As shown, a bottom frame 6 is installed on the bed 1 just below the crossbeam 4, a support platform 61 is installed in the bottom frame 6 so as to be liftable, a second hydraulic cylinder 62 is installed in the bottom frame 6, and the support platform 61 is installed on the second hydraulic cylinder 62 to achieve up and down lifting.

[0050] Specifically, after the substrate moves to above the pad 61, the pad 61 rises, and the first hydraulic cylinder 41 drives the cutter 5 to move downward to punch the substrate on the pad 61. Before the blade of the cutter 5 touches the surface of the substrate, the scraper 52 first contacts the substrate, and in the process of the cutter 5 continuing to move downward, the scraper 52 slides in the inclined direction of the inclined block 511. The scraper 52 scrapes the blade during the movement until the blade cuts the substrate, and the cutter 5 is lifted back to its original position. During the resetting process, the scraper 52 also returns to its original position under the action of the first spring 513, and during the resetting process, it scrapes the surface of the blade again to scrape off the waste residue, thereby cleaning the waste residue adhered to the blade, and the pad 61 is retracted downward, so that when the substrate continues to be pushed forward, it will not contact the pad 61, and can avoid being scratched by the waste residue on the pad 61.

[0051] according to Figure 2 , Figure 3 and Fig. 9 As shown, a guide screw 7 is fixedly installed on the side wall of the bottom frame 6, and the guide screw 7 is driven by a starting motor 71 installed on one side of the bottom frame 6 through a pulley group. A slider 8 is connected to the guide screw 7. The slider 8 slides on the guide screw 7 through the drive of the starting motor 71. A mounting block 9 is vertically connected to the slider 8. The mounting block 9 is vertically placed horizontally above the pad 61, and brush blocks 91 are fixedly connected to the upper and lower sides of the mounting block 9.

[0052] Specifically, after the pad 61 is lowered and retracted, the guide screw 7 is driven to rotate by starting the motor 71, so that the slider 8 moves with the brush block 91. The brush block 91 brushes closely against the surface of the pad 61, and the cutter 5 can also be moved down a certain distance accordingly, so that the blade and the scraper 52 are against the surface of the brush block 91. During the movement of the brush block 91, the waste residue on the pad 61, the blade and the scraper 52 can be pushed to one side. In this way, the waste residue remaining on the pad 61, the blade and the scraper 52 can be cleaned.

[0053] according to Figure 7As shown, an adhesive roller 10 is also rotatably provided on the slider 8, and the height of the adhesive roller 10 is lower than the height of the brush block 91 above the mounting block 9, so that the cutter 5 will not contact the adhesive roller 10 when it abuts against the brush block 91 above the mounting block 9, and the bottom of the adhesive roller 10 is flush with the brush block 91 at the bottom of the mounting block 9. The adhesive roller 10 follows the movement of the slider 8 and rotates on the surface of the pad 61. During the rotation, the waste residue remaining on the pad 61 is picked up, thereby further cleaning the waste residue on the pad 61. A slag collecting box 101 is also provided between the mounting block 9 and the adhesion roller 10. The side of the slag collecting box 101 close to the adhesion roller 10 is a curved edge 102 that fits the surface of the adhesion roller 10. The curved edge 102 is against the surface of the adhesion roller 10. During the rotation of the adhesion roller 10, the waste residue adhered to the adhesion roller 10 can be scraped off by the curved edge 102, and the scraped waste residue will fall into the slag collecting box 101, thereby achieving the purpose of cleaning and collecting the waste residue.

[0054] according to Figure 7 and Figure 8 As shown, a friction belt 63 is wound around the bottom of the pad 61 through a rotating wheel, and the rotating wheel is rotatably installed on both sides of the bottom of the pad 61. The friction belt 63 is wound around the two rotating wheels. The friction belt 63 is a frosted belt. A second drive motor 64 is fixedly installed on one side of the bottom of the pad 61. The second drive motor 64 is connected to one of the rotating wheels to drive the friction belt 63 to rotate.

[0055] Specifically, after the substrate is cut, the substrates on both sides of the pad 61 move back and forth from the pad 61 to the pad 61, specifically, the substrate on the first conveyor belt 21 moves backward and then forward into the gap, while the substrate on the drive roller 3 moves forward and then backward into the gap. The substrates on both sides will slide into the gap between the pad 61 and the bottom frame 6. At this time, the edges of the substrates on both sides are against the friction belt 63, and the edges of the substrates are polished as the friction belt 63 is driven. The polishing of the friction belt 63 can eliminate the burrs formed on the edges of the broken surfaces of the substrates to avoid scratches between the substrates.

[0056] according to Figure 3 and Figure 4 As shown, it also includes: a fixed plate 11 installed on the mounting plate 42, the fixed plate 11 is provided with sliding rods 111 symmetrically slidably on both sides, the second spring 112 is sleeved on the sliding rod 111, and a pressing block 113 is fixedly installed at the bottom of the sliding rod 111. When the pressing block 113 moves downward with the cutter 5, the pressing block 113 first contacts the pad 61. When there is a substrate under the pressing block 113, the pressing block 113 will first abut against the substrate, and as the cutter 5 moves downward, the substrate is tightly pressed to prevent the substrate from moving, so as to avoid the substrate from shifting during the cutting process and causing the cutting size to be skewed.

[0057] according to Figure 1 and Fig.10As shown, it also includes: side frames 12 are arranged on both sides of the first conveyor belt 21 and the second conveyor belt 22, sliding openings 120 are evenly spaced on the side frames 12, a retaining ring 121 is slidably connected in the sliding opening 120, a push rod 122 is arranged in the retaining ring 121, a driving plate 123 is slidably installed in the side frame 12 through a slide rail member 125, an oblique opening 124 matching the push rod 122 is opened on the driving plate 123, a plurality of push rods 122 are slidably connected to the driving plate 123 through a plurality of oblique openings 124, and as the driving plate 123 reciprocates, the push rod 122 in the oblique opening 124 adaptively moves in the sliding opening 120 because the oblique opening 124 follows the movement of the driving plate 123, a first electric push block 126 is fixedly installed on the side frame 12, and the movable end of the first electric push rod 122 is connected to the driving plate 123, thereby pushing the driving plate 123 to move. After the substrate falls on the first conveyor belt 21 and the second conveyor belt 22, the push rods 122 at the two side edges begin to move closer to each other under the action of the driving plate 123, thereby correcting the skewed substrate to avoid cutting the substrate crookedly during the cutting process.

[0058] according to Figure 1 , Fig.11 and Fig.12 As shown, the pushing device includes: a horizontal frame 13, linear guide rails 131 are fixedly installed on both sides of the bed 1, the horizontal frame 13 is driven and installed on the linear guide rails 131 on both sides, and the horizontal frame 13 is driven by the linear guide rails 131 to move back and forth above the first conveyor belt 21, a plurality of base plates 132 are evenly fixedly installed on the horizontal frame 13, a second electric push block 133 is fixedly installed on the base plate 132, a pushing plate 135 is slidably installed at the bottom of the base plate 132, and the pushing plate 135 is connected to the movable rod 134 of the second electric push block 133.

[0059] When the substrate on the first conveyor belt 21 needs to be pushed, the second electric push block 133 drives the push plate 135 downward so that the push plate 135 abuts against the edge of the substrate, and the substrate will be pushed as the horizontal frame 13 moves.

[0060] It should be noted that in order to prevent the movable rod 134 of the second electric push block 133 from being subjected to an external force perpendicular to the rod body for a long time, which may cause the rod body to bend and unable to extend and retract normally, it is necessary to change the connection between the movable rod 134 and the pushing plate 135 into a movable connection. A latch 136 is fixedly arranged at the end of the movable rod 134, and a movable opening 137 allowing the latch 136 to slide is opened on the pushing plate 135. The latch 136 is inserted into the movable opening 137. In this way, the reaction force when the pushing plate 135 is subjected to force will not act on the rod body of the movable rod 134, thereby avoiding deformation and bending of the rod body.

[0061] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
