Description

Technical Field

[0001] This utility model relates to the field of circuit board cutting technology, specifically to a fully automatic circuit board cutting device with bidirectional cutting function. Background Technology

[0002] Circuit boards are important electronic components that provide support for electronic components and serve as an intermediate carrier for electrical connections between electronic components.

[0003] In the electronic circuit manufacturing process, to address the varying shapes and models of circuit boards in different electronic products, it is necessary to process and cut the board-shaped circuit boards. Although cutting machines have a wide range of applications, the current method for cutting circuit boards mostly adopts unidirectional cutting from one side. After completing one cut, the cutting blade needs to return to its previous position to prepare for the next cut, which results in the problem of the cutting blade moving without load, causing waste of resources. At the same time, the blade also causes unnecessary wear on the machine tool during the idle movement, affecting its service life. Summary of the Invention

[0004] In view of the shortcomings of existing technologies that involve idle cutting, the purpose of this utility model is to provide a fully automatic circuit board cutting device with bidirectional cutting function that does not involve idle cutting.

[0005] To solve the above problems, this utility model provides the following technical solution: A fully automatic circuit board cutting device with bidirectional cutting function includes: a main body, which is provided with a feed inlet and a discharge outlet; A clamping mechanism is used to clamp and fix the workpiece that has been moved into the main body; The first set of blades is used to cut the workpiece. The first set of blades has a first state away from the workpiece and a second state close to the workpiece. The second set of blades is used to cut the workpiece. The second set of blades has a third state away from the workpiece and a fourth state close to the workpiece. A drive mechanism is used to drive the first and second tool sets to move and cut the workpiece; When the drive mechanism drives the first and second tool sets to move in the positive direction of the workpiece cutting direction, the first tool set is in a second state close to the workpiece, and the second tool set is in a third state far away from the workpiece. At this time, the first tool set cuts the workpiece. When the drive mechanism drives the first and second tool sets in the opposite direction to the workpiece cutting direction, the first tool set is in a first state of being close to the workpiece, and the second tool set is in a fourth state of being away from the workpiece. At this time, the second tool set cuts the workpiece.

[0006] The beneficial effects of this utility model are: when the workpiece cutting direction is positive, the first set of cutters cuts the workpiece, and when the workpiece cutting direction is negative, the second set of cutters cuts the workpiece. The cutting device will not have the phenomenon of empty tool movement, reducing resource waste and wear on the machine tool during empty tool movement. Attached Figure Description

[0009] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0010] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0011] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0012] like Figures 1-6As shown, this embodiment provides a cutting device 1, which includes a main body 10, a control mechanism 13, a feeding mechanism 20, a clamping mechanism 30, a calibration mechanism 40, a pressing mechanism 50, a cutting mechanism 60, and a unloading mechanism 70. The main body 10 is provided with a feed inlet 11 and a discharge outlet 12. The feed inlet 11 is used for the circuit board to move into the main body 10, and the discharge outlet 12 is used for the circuit board to move out of the main body 10. The control mechanism 13 is provided on the main body and is used to control the operation of the cutting device. The feeding mechanism 20 is provided at the feed inlet 11 and is used to feed the workpiece into the main body 10 through the feed inlet 11. The clamping mechanism 30 is used to clamp and fix one side of the workpiece moved into the main body 10; the calibration mechanism 40 is used to determine the actual position of the workpiece; the control mechanism 13 is used to control the workpiece to move from the actual position to the target cutting position; the clamping mechanism 50 is used to clamp the workpiece calibrated by the calibration mechanism 40, and the clamping mechanism 50 is located on the side of the workpiece away from the clamping mechanism 30; the cutting mechanism 60 is used to cut the workpiece between the clamping mechanism 30 and the clamping mechanism 50; the unloading mechanism 70 is located at the discharge port 12 and is used to remove the cut workpiece from the main body 10. The cutting device is implemented as follows: first, the circuit board is automatically placed into the main body 10 through the feed port by the feeding mechanism 20, without manual feeding. Then, the workpiece clamped by the clamping mechanism 30 is adjusted from the actual position to the target cutting position by the calibration mechanism 13 and the control mechanism 40 to ensure the accuracy of subsequent cutting. The target cutting position is the position that the workpiece should move to during cutting, which is preset in the software. The workpiece is then clamped and fixed on both sides by the clamping mechanism 30 and the pressing mechanism 50 to ensure that it is not loosely fixed due to unilateral fixation during cutting, which could lead to skewed cutting later. After cutting is completed, the workpiece is automatically removed from the main body 10 by the unloading mechanism 70, eliminating the need for manual unloading and making the entire operation more convenient.

[0013] like Figure 1 , Figure 7 As shown, optionally, the feeding mechanism 20 includes a first placement platform 21, a first pick-and-place component 22, and a conveying component 23; the first placement platform 21 is used to place workpieces; the conveying component 23 is used to deliver the workpieces into the main body 10; the first pick-and-place component 22 is used to move the workpieces on the first placement platform 21 to the conveying component 23. Through the arrangement of the first placement platform 21 and the conveying component 23, multiple workpieces to be cut can be placed on the first placement platform 21, and then the first pick-and-place component 22 can pick up one workpiece at a time from the first placement platform 21 and place it in the conveying component 23, eliminating the need for manual operation and reducing the workload of manual operation.

[0014] Optionally, the first placement platform 21 is an inclined placement platform, and it is inclined towards the feed port 11. By arranging the placement platform at an inclination, lateral space can be saved, making it easier to put in larger workpieces.

[0015] like Figure 1 , Figure 7 As shown, optionally, the first pick-and-place component 22 includes a first robotic arm 221. That is, automatic pick-and-place is performed using the first robotic arm 221, making the operation more convenient.

[0016] like Figure 1 , Figure 7 As shown, preferably, the first robotic arm 221 includes a first moving part 22a and a first pick-and-place part 22b; the first pick-and-place part 22b is used to grip or release a workpiece; the first pick-and-place part 22b is disposed on the first moving part 22a, and the first moving part 22a is used to move the first pick-and-place part 22b between the first placement platform 21 and the conveying assembly 23. Specifically, the first pick-and-place part 22b grips a workpiece from the first placement platform 21, then the first moving part 22a moves the workpiece gripped by the first pick-and-place part 22b from the first placement platform 21 to the conveying assembly 23. Afterwards, the first pick-and-place part 22b releases the workpiece and places it on the conveying assembly 23. When a workpiece needs to be gripped again, the first moving part 22a again moves the first pick-and-place part 22b back to the first placement platform 21, and so on.

[0017] The first robotic arm 221 also includes a first swing component 2a2; the first swing component 2a2 is used to adjust the angle of the first pick-and-place section 22b relative to the first placement platform 21, so that the first pick-and-place section 22b can grasp workpieces placed at different angles. By using the first swing component 2a2, the first pick-and-place section 22b can swing, which facilitates the removal of workpieces from the inclined first placement platform 21.

[0018] The first pick-and-place unit 22b includes a first suction cup assembly 2b1; the first suction cup assembly 2b1 is used to pick up and release the workpiece. When the first suction cup assembly 2b1 picks up the workpiece, it can separate the workpiece from the first placement platform 21 or the conveying assembly 23; when the first suction cup assembly 2b1 releases the workpiece, it can place the workpiece onto the conveying assembly 23. The workpiece is picked up and released by using the suction and release functions of the first suction cup assembly 2b1, making it more convenient to use.

[0019] The first robotic arm 221 also includes a first lifting assembly 24, which can drive the first pick-and-place section 22b to move up and down, so that the first pick-and-place section 22b can separate the workpiece from the first placement platform 21 or from the conveying assembly 23.

[0020] like Figure 1 , Figure 7As shown, optionally, there are multiple first suction cup components 2b1, arranged in a rectangular pattern. Using multiple first suction cup components 2b1 prevents problems such as workpiece detachment or ineffective workpiece suction during operation when a single suction cup is used. The rectangular arrangement of the first suction cup components 2b1 effectively suctions the workpiece from all sides, preventing workpiece deformation.

[0021] like Figure 1 Figure 7 As shown, optionally, the first pick-and-place unit 22b further includes a rotating component 2b2; the rotating component 2b2 is used to adjust the angle of the workpiece placed on the conveying component 23. By rotating the rotating component 2b2, the angle of the workpiece placed on the conveying component 23 can be adjusted to ensure that the cutting direction of the workpiece is consistent with the moving direction of the cutting mechanism 60.

[0022] Optionally, the rotating component 2b2 is used to rotate the workpiece held by the first pick-and-place section 22b horizontally after it has gripped the workpiece placed on the conveying component 23, thereby changing the cutting direction of the workpiece during cutting. The operating conditions of the rotating component 2b2 are as follows: the conveying component 23 moves the workpiece into the main body 10, and the cutting mechanism 60 cuts the workpiece; when it is necessary to cut the workpiece in other directions, the conveying component 23 moves the workpiece out of the main body 10, the rotating component 2b2 adjusts the angle of the workpiece, and then the conveying component 23 moves the workpiece into the main body 10 again, and the cutting mechanism 60 cuts the workpiece again.

[0023] like Figure 15 As shown, preferably, the first robotic arm 221 includes a first multi-axis robotic arm 22x and a second pick-and-place section 22n; the second pick-and-place section 22n is used to grasp or release workpieces; the first multi-axis robotic arm 22x enables the second pick-and-place section 22n to move between the first placement platform 21 and the conveying assembly 23. The first multi-axis robotic arm 22x enables the second pick-and-place section 22n to move or swing in any direction, thereby ensuring that the workpiece can be moved from the first placement platform 21 to the conveying assembly 23.

[0024] Optionally, the number of joints of the first multi-axis robotic arm 22x can be three-axis, five-axis, or six-axis; no specific choice is made here.

[0025] Preferably, the first multi-axis robotic arm 22x has five axes.

[0026] Optionally, a partition (not shown in the figure) is also included, which is placed between two adjacent workpieces. The implementation process is as follows: the partition is placed sequentially between two adjacent workpieces on the first placement platform 21 to separate the two adjacent partitions. During the process of placing the workpiece from the first placement platform 21 to the conveying assembly 23, firstly, the workpiece located on the uppermost side of the first placement platform 21 is placed on the conveying assembly 23. Then, the partition between the two workpieces is moved to the workpiece on the conveying assembly 23. Finally, one workpiece on the first placement platform 21 is moved to the partition on the conveying assembly 23. Finally, the conveying assembly 23 moves the two workpieces into the main body 10 at once to cut them. Because there is a partition between the two workpieces during cutting, the upper and lower cutting blades can complete the cutting of the two workpieces at once. At the same time, it can prevent the two adjacent workpieces from being scratched during the movement of the workpieces, resulting in defective products.

[0027] like Figure 1 As shown, optionally, the conveying assembly 23 includes a first power component and a conveyor belt 231; the first power component is used to drive the conveyor belt 231 to move; the conveyor belt 231 is used to drive the workpiece to move into or out of the main body 10. Using the conveyor belt 231 for conveying is simple and convenient.

[0028] like Figure 1 As shown, optionally, the conveyor belt 231 includes multiple sets; the multiple sets of conveyor belts 231 are arranged sequentially at the feed inlet 11, and the upper side of the conveyor belts 231 faces the feed inlet 11. The arrangement of multiple sets of conveyor belts 231 can be used to convey workpieces of different sizes, and can reduce the resistance when the conveyor belts 231 are a whole, that is, only the conveyor belts 231 carrying workpieces have a certain driving resistance.

[0029] like Figure 3 As shown, optionally, the cutting device 1 also includes an anti-blocking mechanism 80; the anti-blocking mechanism 80 is disposed between the clamping mechanism 50 and the feeding mechanism 30, and is used to support the workpiece. Because the anti-blocking mechanism 80 is located between the clamping mechanism 50 and the feeding mechanism 30, it supports the lower side of the workpiece when it moves towards the main body via the conveying assembly 23, preventing the gap between the clamping mechanism 50 and the feeding mechanism 30 from preventing the workpiece from properly entering the main body 10.

[0030] like Figure 3 As shown, optionally, the anti-blocking mechanism 80 includes a roller 81; the upper end face of the roller 81 is flush with the lower side of the clamping position of the clamping mechanism 30, and the workpiece can drive the roller 81 to rotate when the workpiece enters the main body 10. The fact that the roller 81 can rotate can effectively ensure that the workpiece and the roller 82 will not make hard contact, thus preventing the workpiece from deforming.

[0031] like Figure 2 as well as Figures 8-9 As shown, optionally, the clamping mechanism 30 includes a second power member 31 and a clamping part 32; the second power member 31 is used to drive the clamping part 32 to clamp or release the workpiece; when the workpiece is moved into the main body 10 by the feeding mechanism 20, the second power member 31 drives the clamping part 32 to clamp the workpiece; when the workpiece is cut by the cutting mechanism 60, the second power member 31 drives the clamping part 32 to release the workpiece. That is, after the conveying assembly 23 moves the workpiece into the main body 10, the workpiece is sent to the clamping part 32, and under the action of the second power member 31, the clamping part 32 clamps the workpiece, fixing one side of the workpiece.

[0032] like Figure 8 As shown, optionally, the clamping part 32 includes a positioning member 321 and a swing member 322; the swing member 322 can swing closer to or away from the fixed member; when the swing member 322 swings towards the positioning member 321, the workpiece can be clamped; when the swing member 322 swings away from the positioning member 321, the workpiece can be removed. The positioning member 321 can ensure that the lowest position of the workpiece does not change, ensuring the cutting height positioning during cutting. The swing member 322 can stably clamp the workpiece on the positioning member 321, ensuring the stability of the workpiece.

[0033] Optionally, the second power component 31 includes a telescopic component; the telescopic component is located on the positioning component 321, and the telescopic component can push the positioning component 321 to translate, thereby causing the swing component 322 to swing closer to or away from the positioning component 321.

[0034] Preferably, the telescopic component is a cylinder.

[0035] Optionally, the second power component includes a forward and reverse motor, which is connected to the swing member 322. The forward and reverse motor drives the swing member 322 to swing closer to or further away from the positioning member 321. The forward and reverse motor is connected to the swing position of the swing member 322, and the forward and reverse motor drives the swing member 322 to swing through the swing position.

[0036] Optionally, the forward and reverse rotating motor is a three-phase asynchronous motor; the specific model is not specified here.

[0037] like Figure 8 As shown, optionally, the clamping mechanism 30 can be in multiple sets, arranged in a manner that clamps one side of the workpiece. This design with multiple clamping mechanisms 30 ensures that one side of the workpiece is completely clamped, preventing wobbling due to incomplete clamping.

[0038] Optionally, the positioning element 321 and the swing element 322 may be serrated on the side that presses against the workpiece. The serrated arrangement can increase the clamping force and ensure the stability of the clamping.

[0039] Optionally, the positioning member 321 and the swing member 322 have a hard rubber layer on the side that holds the workpiece. The hard rubber layer ensures that the workpiece is clamped while preventing embossing.

[0040] like Figure 2 As shown, optionally, the calibration mechanism 40 includes an identification mechanism 41; the identification mechanism 41 is used to identify the actual position of the workpiece and transmit the identified position information to the control mechanism. That is, after the workpiece is moved to the main body 10, the identification mechanism 41 identifies the workpiece to determine its actual position.

[0041] like Figures 1-2 As shown, optionally, the recognition mechanism 41 includes a CCD camera 411. The CCD camera 411 can capture images of reference points on the workpiece and transmit the images to the control mechanism 13. The control mechanism 13 recognizes the reference point position based on the image, obtains the actual coordinates of the reference point, and compares the actual coordinates of the reference point with the preset target coordinates of the reference point to determine the workpiece movement path. The workpiece movement path is used to move the workpiece from its actual position to the target cutting position. By using the CCD camera 411 to recognize the workpiece position, the actual position of the workpiece can be determined, thereby ensuring the accuracy of the position.

[0042] like Figure 3 , Figure 9 As shown, optionally, the cutting device 1 also includes a drive assembly 42. The drive assembly 42 is located within the main body 10. The control mechanism 13 controls the drive assembly 42 to drive the clamping mechanism 30 to move according to the actual position of the workpiece. The drive assembly 42 causes the clamping mechanism 30 to move the workpiece within the main body 10, moving the workpiece from its actual position to the target cutting position. By setting the drive assembly 42, when the actual position of the workpiece differs from the target cutting position, the control mechanism 13 controls the drive assembly 42 to move the workpiece from its actual position to the target cutting position, thereby completing the workpiece position calibration and ensuring the accuracy of the cutting.

[0043] like Figure 3 , Figure 9 As shown, optionally, the drive assembly 42 includes a first drive unit 421, a second drive unit 422, and a mounting member 423; the first drive unit 421 is rotatably connected to one end of the mounting member 423, and the second drive unit 422 is rotatably connected to the other end of the mounting member 423. The first drive unit 421 and the second drive unit are arranged in parallel, and the clamping mechanism 30 is mounted on the mounting member 423; the first drive unit and the second drive unit are used to drive the corresponding side of the mounting member 423 to move. By driving the corresponding movement of the mounting member 423 by the first drive unit 421 and the second drive unit 422 respectively, the workpiece clamped by the clamping mechanism 30 can be translated and its horizontal angle adjusted, ensuring that the actual position of the workpiece coincides with the target cutting position and ensuring the accuracy of the cutting.

[0044] like Figure 3 , Figure 9 As shown, optionally, the first driving unit 421 and the second driving unit 422 can be driven individually or simultaneously by the control mechanism. When the first driving unit 421 or the second driving unit 422 is driven individually, the angle between the mounting member 423 and the workpiece cutting direction of the cutting assembly changes, thereby changing the cutting angle of the workpiece held by the clamping mechanism 30. When the first driving unit 421 and the second driving unit 422 are driven simultaneously, both ends of the mounting member 423 move toward the cutting assembly at the same speed. By driving individually and simultaneously, the actual cutting position of the workpiece is accurately moved to coincide with the target cutting position, thereby ensuring the accuracy of the cutting.

[0045] like Figure 3 , Figure 9 As shown, optionally, both the first drive unit 421 and the second drive unit 422 include a third power component 42a, a track 42b, and a slider 42c. The track 42b is installed inside the main body 10, the slider 42c is disposed on the track 42b, and the mounting component 423 is disposed on the slider 42c. The third power component 42a pushes the slider 42c to move along the track 42b. The mounting component 423 is rotatable relative to the slider 42c. By setting the track 42b, the workpiece cutting position can be quickly adjusted. By allowing the mounting component 423 to rotate relative to the slider 42c, the cutting direction of the workpiece can be ensured to coincide with the cutting direction of the cutting mechanism 60.

[0046] Optionally, the mounting component 423 is rotatably mounted to one of the sliders 42c; the mounting component 423 is connected to the other slider 42c via a first elastic element 42d, which is located on the side of the corresponding slider 42c away from the other slider 42c. The first elastic element 42d allows the mounting component 423 to rotate. When the mounting component rotates, it compresses / stretches the first elastic element, causing displacement and resulting in inconsistent positions on both sides of the mounting component. For example, if both sides of the mounting component were originally at coordinate 5 on the coordinate axis, after rotation, one side of the mounting component would have coordinate 5, and the other side would have coordinate 4, thereby changing the angle of the workpiece fixed to the mounting component and achieving multi-dimensional calibration of the workpiece.

[0047] like Figure 6 , Figure 13As shown, optionally, the clamping mechanism 50 includes a support member 51 and a clamping part 52; the end face of the support member 51 is flush with the clamping position of the clamping mechanism 30; the clamping part 52 can move away from or towards the support member 51; when the clamping part 52 moves towards the support member 51, the workpiece can be clamped to the support member 51 by the clamping part 52; when the clamping part 52 moves away from the support member 51, the workpiece can move. The end face of the support member 51 is flush with the clamping position of the clamping mechanism 30 to prevent workpiece deformation due to height difference, thereby affecting the cutting position of the workpiece. Furthermore, the clamping of the clamping mechanism 50 effectively fixes the workpiece on both sides of the cutting position, ensuring stable cutting.

[0048] like Figure 6 , Figure 13 As shown, optionally, the clamping part 52 includes a telescopic member 52a and a pressure plate 52b; the telescopic member 52a drives the pressure plate 52b away from or towards the support member 51. By using the telescopic member 52a to drive the pressure plate 52b to clamp the workpiece, the clamping force is effectively guaranteed.

[0049] Optionally, the pressure plate 52b is provided with a hard rubber layer on one side of the support member 51; while ensuring that the workpiece is pressed tightly, it prevents the workpiece from being dented.

[0050] like Figures 3-4 As shown, optionally, the cutting device 1 also includes a support frame 90; the support frame 90 is disposed inside the main body 10, and the upper side of the support frame 90 is flush with the lower side of the clamping position of the clamping mechanism 30; when the clamping mechanism 50 clamps the workpiece, the workpiece located inside the main body 10 comes into contact with the support frame 90. The support frame 90 effectively supports the workpiece located inside the main body 10 after the clamping mechanism 30 clamps the workpiece, preventing workpiece deformation from affecting subsequent cutting.

[0051] like Figures 3-4 As shown, optionally, the support frame 90 includes a frame portion 91 and a plurality of rollers 92; the plurality of rollers 92 are disposed on the frame portion 91, and the upper side of the plurality of rollers 92 is flush with the lower side of the clamping position of the clamping mechanism 30; the plurality of rollers 92 can contact the workpiece. By adopting the arrangement of rollers 92, when the workpiece is calibrated, the workpiece makes rolling contact with the rollers 92, so that the workpiece will not generate hard friction, and thus the problem of workpiece wear will not occur.

[0052] like Figure 2 , Figures 5-6 as well as Figure 10-11 As shown, optionally, the cutting mechanism 60 includes a cutting section 61 and a driving mechanism 62; the driving mechanism 62 is used to drive the cutting section 61 to move along the workpiece cutting direction, and the cutting section 61 cuts the workpiece. By driving the cutting section 61 to cut the workpiece through the driving mechanism 62, the problem of cutting deviation caused by the vibration of the workpiece when driving the workpiece can be prevented.

[0053] like Figures 10-11 As shown, in one embodiment, the cutting unit 61 includes a first cutting component 611 and a second cutting component 612. When the workpiece is moved into the main body 10, the first cutting component 611 is located above the workpiece, and the second cutting component 612 is located below the workpiece. The first cutting component 611 can cut the upper side of the workpiece, and the second cutting component 612 can cut the lower side of the workpiece. By having the first cutting component 611 cut the upper side of the workpiece and the second cutting component 612 cut the lower side of the workpiece, it can be ensured that no burrs will appear on both sides of the cut position after the cutting is completed, thus preventing the plate surface from cracking due to burrs and resulting in defective products.

[0054] like Figures 10-11 As shown, optionally, the first cutting assembly 611 includes a first cutting element 6a1, a second cutting element 6a2, a fourth power element 6a5, and a fifth power element 6a6; the fourth power element 6a5 is used to drive the first cutting element 6a1 away from or closer to the workpiece, and the fifth power element 6a6 is used to drive the second cutting element 6a2 away from or closer to the workpiece; the second cutting assembly 612 includes a third cutting element 6a3, a fourth cutting element 6a4, a sixth power element 6a7, and a seventh power element 6a8; the sixth power element 6a7 is used to drive the third cutting element 6a3 away from or closer to the workpiece, and the seventh power element 6a8 is used to drive the fourth cutting element 6a3 away from or closer to the workpiece. Cutting elements 6a1 and 6a3 are symmetrical about the workpiece; cutting elements 6a2 and 6a4 are also symmetrical about the workpiece. When cutting elements 6a1 and 6a3 are close to the workpiece, cutting elements 6a2 and 6a4 are far from the workpiece, and cutting elements 6a1 and 6a3 cut the workpiece. When cutting elements 6a2 and 6a4 are close to the workpiece, cutting elements 6a1 and 6a3 are far from the workpiece, and cutting elements 6a2 and 6a4 cut the workpiece. By arranging the first and third cutting elements 6a1 and 6a3, and the second and fourth cutting elements 6a2 and 6a4, respectively, the workpiece can be cut from either side of the cutting direction. This eliminates the need to switch between cutting elements, preventing the cutting elements from returning to their original positions after each cut and thus preventing idle cutting.

[0055] like Figure 17As shown, in another embodiment, the cutting unit 61 includes a first blade group 61a and a second blade group 61b. The first blade group 61a is used to cut the workpiece and has a first state away from the workpiece and a second state close to the workpiece. The second blade group 61b is used to cut the workpiece and has a third state away from the workpiece and a fourth state close to the workpiece. The driving mechanism 62 is used to drive the first blade group 61a and the second blade group 61b to move and cut the workpiece. When the driving mechanism 62 drives the first blade group 61a and the second blade group 61b to move in the positive direction of the workpiece cutting direction, the first blade group 61a is in the second state close to the workpiece, and the second blade group 61b is in the third state away from the workpiece, at which time the first blade group 61a cuts the workpiece. When the driving mechanism 62 drives the first blade group 61a and the second blade group 61b in the opposite direction of the workpiece cutting direction, the first blade group 61a is in the first state close to the workpiece, and the second blade group 61b is in the fourth state away from the workpiece, at which time the second blade group 61b cuts the workpiece. When cutting in the forward direction of the workpiece cutting direction, the first cutter group 61a cuts the workpiece, and when cutting in the reverse direction, the second cutter group 61b cuts the workpiece. The cutting device 1 will not experience idle cutting, thus reducing resource waste and wear on the machine tool during idle cutting.

[0056] Optionally, the first cutter group 61a includes a first cutting element 6a1 and a third cutting element 6a3; the first cutting element 6a1 and the third cutting element 6a3 are symmetrical about the workpiece vertically; when the first cutter group 61a is in the second state close to the workpiece, both the third cutting element and the first cutting element 6a1 are close to the workpiece, and the first cutting element 6a1 and the third cutting element 6a3 can cut the workpiece simultaneously. The symmetry of the first cutting element 6a1 and the third cutting element 6a3 about the workpiece vertically ensures that the cutting of both the upper and lower sides can be effectively completed during workpiece cutting.

[0057] Optionally, a fourth power component 6a5 and a sixth power component 6a7 are also included; the fourth power component 6a5 is used to move the first cutting component 6a1 away from or closer to the workpiece, and the sixth power component 6a7 is used to move the third cutting component 6a3 away from or closer to the workpiece. The fourth power component 6a5 and the sixth power component 6a7 can ensure that the first cutting component 6a1 and the third cutting component 6a3 are close to the workpiece during cutting operations and away from the workpiece when not cutting.

[0058] Optionally, the second cutter assembly 61b includes a second cutting element 6a2 and a fourth cutting element 6a4; the second cutting element 6a2 and the fourth cutting element 6a4 are symmetrical about the workpiece vertically; when the second cutting element 6a2 is in the second state close to the workpiece, both the fourth cutting element 6a4 and the second cutting element 6a2 are close to the workpiece, and the second cutting element 6a2 and the fourth cutting element 6a4 can cut the workpiece simultaneously. This ensures that the cutting of the upper and lower sides can be effectively completed when cutting the workpiece.

[0059] Optionally, a fifth power component 6a6 and a seventh power component 6a8 are also included; the fifth power component 6a6 is used to move the second cutting component 6a2 away from or closer to the workpiece; the seventh power component 6a8 is used to move the fourth cutting component 6a4 away from or closer to the workpiece. The fifth power component 6a6 and the seventh power component 6a8 can ensure that the second cutting component 6a2 and the fourth cutting component 6a4 are close to the workpiece during cutting operations and away from the workpiece when not cutting.

[0060] Optionally, the first cutting element 6a1 and the second cutting element 6a2 are located on the same side of the workpiece, while the third cutting element 6a3 and the fourth cutting element 6a4 are located on the other side of the workpiece. This same-side design ensures that the cutting device 1 will not experience idle cutting.

[0061] Optionally, when the first cutting element 6a1 and the third cutting element 6a3 cut the workpiece, the interval between adjacent sides of the first cutting element 6a1 and the third cutting element 6a3 is between 0.2 and 0.5 mm. Maintaining a 0.2-0.5 mm interval between adjacent sides of the first cutting element 6a1 and the third cutting element 6a3 during workpiece cutting can prevent the workpiece from being cut off and difficult to remove, and also prevent the first cutting element 6a1 and the third cutting element 6a3 from colliding.

[0062] Optionally, when the second cutting element 6a2 and the fourth cutting element 6a4 cut the workpiece, the interval between adjacent sides of the second cutting element 6a2 and the fourth cutting element 6a4 is between 0.2 and 0.5 mm. Maintaining a 0.2-0.5 mm interval between adjacent sides of the second cutting element 6a2 and the fourth cutting element 6a4 during workpiece cutting can prevent the workpiece from being cut off and difficult to remove, and also prevent the second cutting element 6a2 and the fourth cutting element 6a4 from colliding.

[0063] like Figures 10-11As shown, optionally, the first cutting element 6a1 includes a first cutting blade a1; the second cutting element 6a2 includes a second cutting blade a2; the third cutting element 6a3 includes a third cutting blade a3; and the fourth cutting element 6a4 includes a fourth cutting blade a4. The first cutting blade a1 and the second cutting blade a2 are located on one side of the workpiece with opposite cutting edge directions; the third cutting blade a3 and the fourth cutting blade a4 are located on one side of the workpiece with opposite cutting edge directions; the first cutting blade a1 and the third cutting blade a3 are located on one side of the workpiece with opposite cutting edge directions; and the second cutting blade a2 and the fourth cutting blade a4 are located on one side of the workpiece with opposite cutting edge directions. By employing first cutting blade a1 and second cutting blade a2 with opposite cutting edge directions on one side of the workpiece, and third cutting blade a3 and fourth cutting blade a4 with opposite cutting edge directions on one side of the workpiece, it can be ensured that when cutting the workpiece from one side of either of the two directions of the cutting assembly's movement direction, there is always one cutting blade cutting the workpiece. Similarly, by employing first cutting blade a1 and third cutting blade a3 with opposite cutting edge directions on one side of the workpiece, and second cutting blade a2 and fourth cutting blade a4 with opposite cutting edge directions on one side of the workpiece, it can be ensured that when cutting the workpiece from one side of either of the two directions of the cutting assembly's movement direction, there is always one cutting blade cutting the upper and lower sides of the workpiece.

[0064] Because the cutting blade has a unidirectional cutting edge, each cutting blade can only cut in one direction.

[0065] like Figures 10-11 As shown, optionally, the cutting mechanism 60 also includes four suction channels 63; the four suction channels 63 are located on the side of the cutting section 61 away from the workpiece, and each suction channel 63 is connected to the corresponding cutting blade, and each suction channel 63 is connected to an external suction pipe. By having each cutting blade connected to a suction channel 63, the dust generated during cutting can be sucked out in a timely manner, preventing a large amount of dust from affecting the performance of the cutting device 1.

[0066] like Figure 2 as well as Figures 4-5 As shown, optionally, the drive mechanism 62 includes a third drive unit 621 and a fourth drive unit 622; the third drive unit 621 is used to drive the first cutting component 611 to cut the upper side of the workpiece along the workpiece cutting direction, and the fourth drive unit 622 is used to drive the second cutting component 612 to cut the lower side of the workpiece along the workpiece cutting direction. By using the third drive unit 621 and the fourth drive unit 622 to drive the corresponding cutting components to move, the upper and lower parts are cut simultaneously during cutting, thus improving cutting efficiency.

[0067] like Figure 2 as well as Figures 4-5As shown, optionally, the drive mechanism 62 includes a slide rail 101, a mounting component 102, and a power unit 103; the slide rail 101 is mounted on the main body 10; the power unit 103 drives the mounting component 102 to move along the slide rail 101, and the cutting part 61 is mounted on the mounting component 102. This ensures that the direction of the slide rail 101 aligns with the workpiece cutting direction, preventing skewing during cutting, and that the cutting is performed stably under the drive of the power unit 103.

[0068] like Figure 2 , Figure 12 As shown, optionally, the power unit 103 includes a stator 3a and a mover 3b; the stator 3a is disposed on the main body 10, and the mover 3b is disposed on the mounting member 102, and the mover 3b drives the mounting member 102 to move via the stator 3a. Through the cooperation of the stator 3a and the mover 3b, the movement of the cutting mechanism 60 can be stably realized.

[0069] Optionally, the stator includes a permanent magnet steel plate; the mover 3b includes a conductive magnet; after the conductive magnet conducts electricity, it moves the mounting component under the magnetic attraction of the permanent magnet steel plate. This electromagnetic coordination forms an electromagnetic track drive system, which can prevent the noise generated when using gear transmission.

[0070] Optionally, there are two sets of slide rails 101, with the two sets of slide rails 101 located on both sides of the stator 3a. The design of two sets of slide rails 101 can stably realize the movement of the cutting mechanism 60.

[0071] Optionally, the power unit includes a telescopic rod; the telescopic rod propels the mounting component to move. The telescopic rod's extension and retraction makes operation more convenient and reduces wear.

[0072] Optionally, the telescopic rod may include a pneumatic or hydraulic cylinder.

[0073] Preferably, the telescopic rod is a cylinder.

[0074] like Figure 3 , Figure 14 As shown, optionally, the unloading mechanism 70 includes a second placement platform 71 and a second pick-and-place assembly 72; the second placement platform 71 is used to place the cut workpiece; the second pick-and-place assembly 72 is used to move the cut workpiece through the discharge port 12 to the second placement platform 71. With the second placement platform 71, the workpiece can be removed from the clamping mechanism 30 by the second pick-and-place assembly 72 and then moved to the second placement platform 71 without manual operation, reducing the workload of manual operation.

[0075] Optionally, the second placement platform 71 is an inclined placement platform, tilted towards the discharge port 12. By arranging the placement platform at an incline, lateral space can be saved, making it easier to put the cut workpieces in.

[0076] Optionally, the second pick-and-place component 72 includes a second robotic arm 721. That is, automatic pick-and-place is performed using the second robotic arm 721, making the operation more convenient.

[0077] like Figure 3 , Figure 14 As shown, optionally, the second robotic arm 721 includes a second moving part 72a and a third pick-and-place part 72b; the third pick-and-place part 72b is used to grip or release a workpiece; the third pick-and-place part 72b is disposed on the second moving part 72a, and the second moving part 72a is used to move the third pick-and-place part 72b between the clamping mechanism 30 and the second placement platform 71. That is, when the third pick-and-place part 72b is removed from the clamping mechanism 30, the first placement platform 21 grips the workpiece, and then the second moving part 72a moves the workpiece gripped by the third pick-and-place part 72b from the clamping mechanism 30 to the second placement platform 71. When it is necessary to grip a workpiece again, the second moving part 72a again moves the third pick-and-place part 72b back to the clamping mechanism 30, and so on.

[0078] like Figure 3 , Figure 14 As shown, optionally, the second robot arm 721 also includes a second swing assembly 7a2; the second swing assembly 7a2 is used to adjust the angle of the third pick-and-place section 72b relative to the second placement platform 71, so that the workpiece is placed on the second placement platform 71 at different angles. By using the second swing assembly 7a2, the third pick-and-place section 72b can swing, which facilitates placing the workpiece on the inclined second placement platform 71.

[0079] Optionally, the second robotic arm 721 also includes a second lifting assembly 73, which can drive the third pick-and-place section 72b to move up and down, so that the third pick-and-place section 72b can separate the workpiece from the second placement platform 71 or from the clamping mechanism 30.

[0080] like Figure 3 , Figure 14 As shown, optionally, the third pick-and-place unit 72b includes a second suction cup assembly 7b1; the second suction cup assembly 7b1 is used to pick up and release the workpiece. When the second suction cup assembly 7b1 picks up the workpiece, it can separate the workpiece from the clamping assembly 30; when the second suction cup assembly 7b1 releases the workpiece, it can place the workpiece on the second placement platform 71. The workpiece is picked up and released by using the suction and release functions of the second suction cup assembly 7b1, making it more convenient to use.

[0081] Optionally, there are multiple second suction cup assemblies 7b1, arranged in a rectangular pattern. Using multiple second suction cup assemblies 7b1 prevents problems such as workpiece detachment or failure to effectively pick up the workpiece during suction operations when a single suction cup is used. The rectangular arrangement of the second suction cup assemblies 7b1 effectively adheres to the workpiece from all sides, preventing workpiece deformation.

[0082] like Figure 16 As shown, optionally, the second robotic arm 721 includes a second multi-axis robotic arm 72x and a fourth pick-and-place section 72n; the fourth pick-and-place section 72n is used to pick up or release a workpiece; the second multi-axis robotic arm 72x enables the fourth pick-and-place section 72n to move between the clamping mechanism 30 and the second placement platform 71.

[0083] Its second multi-axis robotic arm 72x can move or swing the fourth pick-and-place unit 72n in any direction, thereby ensuring that the workpiece can be moved from the clamping mechanism 30 to the second placement platform 71.

[0084] Optionally, the second multi-axis robotic arm 72x may have one of three, five, or six axes of joints. No specific choice is made here.

[0085] Preferably, the second multi-axis robotic arm 72x is five-axis.

[0086] In summary, this utility model provides a fully automatic circuit board cutting device with bidirectional cutting function. When the workpiece cutting direction is forward, the first blade group cuts the workpiece, and when the workpiece cutting direction is reverse, the second blade group cuts the workpiece. The cutting device will not have the phenomenon of empty tool movement, reducing resource waste and wear on the machine tool during empty tool movement.
