Description

Technical Field

[0002] In the production of electronic products, circuit boards are essential components. In order to meet the needs of electronic products of different sizes, cutting a large circuit board is a very common technical means. In order to improve the accuracy of cutting, it is often necessary to align the circuit board before cutting. However, in the current existing technology, there are the following problems in the process of cutting circuit boards:

[0003] 1. The efficiency of conveying the circuit board from loading to adjusting the alignment position and then moving it to the cutting position is low. After the cutting is completed, it is necessary to wait for the adjustment and then move it to the cutting position. The whole process takes too long;

[0004] 2. During the cutting process, the clamping of the circuit board is unstable, and the circuit board is very easy to deviate, resulting in the cutting deviation and damage to the circuit board. The defective rate of the product is high, resulting in a huge waste of resources;

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] refer to Figure 1-18 .

[0047] like Figure 1-2As shown, the present invention discloses a circuit board cutting machine, comprising a frame 1, on which a loading position 11, an adjustment position 12, a cutting position 13 and a discharging position 14 are sequentially arranged, and a transport mechanism 2 which can move between the loading position 11, the adjustment position 12 and the cutting position 13 and is used to transport circuit boards is slidably connected to the frame 1, a cutting mechanism 3 is arranged on the cutting position 13, and a discharging mechanism 4 is arranged between the cutting position 13 and the discharging position 14 or on the discharging position 14; wherein the transport mechanism 2 includes a transport mechanism 2 which moves between the loading position 11 and the adjustment position 12 and the cutting position 13 and is used to transport circuit boards; a cutting mechanism 3 is arranged on the cutting position 13, and a discharging mechanism 4 is arranged between the cutting position 13 and the discharging position 14 or on the discharging position 14; wherein, the transport mechanism 2 includes a transport mechanism 2 which moves between the loading position 11 and the adjustment position 12 and the cutting position 13 and is used to transport circuit boards; The conveying mechanism 2 comprises a first clamping assembly 21 between the adjustment position 12, a second clamping assembly 22 moving between the adjustment position 12 and the cutting position 13, and a conveying frame 23 fixedly connected to the first clamping assembly 21 and the second clamping assembly 22 respectively, the conveying frame 23 slides on the frame 1 to synchronously drive the first clamping assembly 21 and the second clamping assembly 22 to switch the workstations; the transport mechanism 2 is also fixedly provided with a driving assembly 24, and the driving assembly 24 can drive the first clamping assembly 21 and the second clamping assembly 22 to slide synchronously.

[0048] It should be noted that a movable adjustment component 5 for adjusting the cutting position of the circuit board to be cut and a camera module 51 corresponding to the movable adjustment component 5 are also provided on the adjustment position 12. The camera module 51 is located above the movable adjustment component 5 and is fixedly or slidably connected to the frame 1.

[0049] In addition, the present invention also provides a display screen and a plurality of buttons electrically connected to each mechanism inside the frame 1 outside the frame 1, and the operation steps of each mechanism can be driven and viewed on the display screen by operating the buttons;

[0050] During operation, the staff only needs to place the circuit board to be cut on the loading position 11, and by key operation, the driving component 24 on the transport mechanism 2 can be started to drive the first clamping component 21 and the second clamping component 22 to move synchronously toward the loading position 11, until the first clamping component 21 corresponds to the loading position 11, and the second clamping component 22 corresponds to the adjustment position 12;

[0051] Next, the first clamping assembly 21 sucks the circuit board to be cut located at the loading position 11, and at the same time, the second clamping assembly 22 clamps the circuit board that has been adjusted at the adjustment position 12. After clamping, the second clamping assembly 22 synchronously moves away from the loading position 11 again. During the movement, the circuit board clamped by the second clamping assembly 22 is cut by the cutting mechanism 3 at the same time.

[0052] When the cutting is completed, the first clamping component 21 will move to the adjustment position 12 accordingly and release the clamping of the circuit board, and the second clamping component 22 will move completely to the cutting position 13 and simultaneously release the clamping of the circuit board. The first clamping component 21 and the second clamping component 22 will move synchronously toward the loading position 11 again to continue to convey the next group of circuit boards. During the movement, the moving adjustment component 5 will calibrate the position of the circuit board located at the adjustment position 12 to ensure that the subsequent cutting is more accurate. When the second clamping component 22 moves to the adjustment position 12, the circuit board on the adjustment position 12 will also be proofread and waiting for transportation. Therefore, the second clamping component 22 can immediately clamp the circuit board and transport it again without waiting, so as to achieve the coincidence of feeding and cutting time, and the coincidence of movement and alignment time, which takes less time and is more efficient. The cut circuit board will be transferred out by the discharging mechanism 4 in time, so that the whole cutting process is more compact and occupies less space. The structure of each mechanism is simple, which not only effectively improves the production efficiency, but also improves the cutting accuracy, reduces the defective rate, and saves production costs.

[0053] Specifically, Figure 3-5 As shown, the first clamping assembly 21 includes a first connecting plate 211 and a plurality of second connecting plates 212, and one end of at least one of the second connecting plates 212 is slidably connected to the first connecting plate 211; wherein, a suction portion 213 is provided on the second connecting plate 212, and the suction portion 213 is used to suck the circuit board located on the loading position 11 so as to transfer it to the adjustment position 12. In this embodiment, the suction portion 213 includes a cylinder 1 2131 and a suction cup 2132, wherein the cylinder 1 2131 is fixedly connected to the second connecting plate 212, and the output end of the cylinder 1 2131 passes through the second connecting plate 212 and is fixedly connected to the suction cup 2132, and the suction cup 2132 is driven to descend toward the position of the circuit board until it can suck the circuit board to drive the circuit board to move from the loading position 11 to the adjustment position 12.

[0054] like Figure 6As shown, in another embodiment, in order to ensure the stability of the several suction parts 213 on the second connecting plate 212 when sucking circuit boards, it is necessary to ensure that the lifting and lowering amplitudes of the several suction parts 213 are consistent. To this end, only one cylinder 2131 that drives the suction parts 213 to lift and lower can be set and is set on the conveying frame 23 and fixedly connected thereto, wherein the output shaft of the cylinder 2131 is screwed and fixed to the first clamping assembly 21. In addition, in order to enhance the balance of the first clamping assembly 21, an "L"-shaped frame 231 is provided on the conveying frame 23, one side of the "L"-shaped frame 231 is slidably connected to the cylinder 1 2131, and different surfaces on the other side are respectively fixedly connected to the output shaft of the cylinder 1 2131 and the first connecting plate 211 of the first clamping assembly 21. Through the drive of the cylinder 1 2131, the "L"-shaped frame 231 and the first clamping assembly 21 are synchronously lifted and lowered to achieve the effect of synchronous lifting and lowering of the suction part 213. By setting one cylinder 1 2131 to control the lifting and lowering of multiple suction parts 213, not only the firmness of the suction part 213 can be ensured, but also the structure can be optimized and the use of parts can be reduced. It is also possible that at least one of the suction parts 213 on the second connecting plate 212 can be adjusted along the length direction of the second connecting plate 212, so that the user can adjust the position of the suction part 213 according to the size of the circuit board, so that the present invention is flexible and diverse in use, easy to operate, and more practical.

[0055] Furthermore, if Figure 3-4 As shown, the second clamping assembly 22 includes two groups of pressure plate assemblies 221 with the same upper and lower structures. The two groups of pressure plate assemblies 221 are symmetrically arranged on the cutting position 13 and are used to clamp and fix the upper and lower end surfaces of the circuit board together. The pressure plate assembly 221 includes a bottom plate 2211, a plurality of pressure blocks 2212, and a plurality of cylinders 2213 fixed on the bottom plate 2211 for driving the pressure blocks 2212 to rise and fall. The output shaft of the cylinder 2213 is fixedly connected to the pressure blocks 2212. By setting the cylinder 2213 and the pressure blocks 2212 to be fixedly connected, the relative or opposite movement of the upper and lower groups of pressure blocks 2212 can be achieved. When clamping the circuit board, the upper and lower groups of pressure blocks 2212 are respectively driven by the corresponding cylinders 2213 and move closer to each other until the circuit board can be firmly clamped; when the clamping of the circuit board needs to be released, the two groups of pressure blocks 2212 move in opposite directions and move away from each other. At the same time, the up and down movement of the pressing block 2212 can also clamp circuit boards of other different thickness specifications, making the present invention more practical, flexible and diverse in application, and better able to meet production needs.

[0056] Furthermore, since the pressure plate assembly 221 also needs to make a reciprocating motion of a certain distance to achieve switching of different workstations of the circuit board, the transportation mechanism 2 is also fixed with two driving assemblies 24 respectively corresponding to the two groups of the pressure plate assemblies 221, and the driving assembly 24 includes a driving member 241, a transmission wheel 242 and a transmission belt 243 connected to the transmission wheel 242. The driving member 241 drives the transmission wheel 242 to rotate, thereby driving the transmission belt 243 to rotate synchronously. A sliding block 2214 is provided on the bottom plate 2211 in the pressure plate assembly 221, one end of the sliding block 2214 is fixedly connected to the bottom plate 2211, and the other end is fixedly connected to the transmission belt 243. When the driving member 241 drives the transmission wheel 242 to rotate, the transmission belt 243 wound on the transmission wheel 242 will rotate synchronously, and the sliding block 2214 is fixedly connected to the transmission belt 243. Therefore, the sliding block 2214 will slide synchronously, thereby driving the pressure plate assembly 221 fixedly connected thereto.

[0057] Furthermore, if Figure 7-11As shown, the cutting mechanism 3 includes two sets of mounting plates 31 which are arranged correspondingly and have the same structure. A cutting assembly 32 and a transmission assembly 33 are fixed on the mounting plate 31. The two transmission assemblies 33 are respectively arranged on both sides of the mounting plate 31. The cutting assembly 32 includes a cutting knife 321 and a second driving member 322. The cutting knife 321 and the second driving member 322 are respectively arranged on both sides of the mounting plate 31. The output shaft of the second driving member 322 passes through the mounting plate 31 and is fixedly connected to the cutting knife 321. It is noted that the mounting plate 31 is provided with a avoidance groove 311 for avoiding the cutting knife 321 and a groove cover 312 adapted to the avoidance groove 311. The cutting knife 321 is located in the avoidance groove 311 and at least partially extends out of the avoidance groove 311 during cutting. Therefore, the position of the cutting knife 321 is still between the two conveying components 33. The cutting component 32 and the conveying component 33 are independent of each other and do not interfere with each other. That is to say, when the cutting knife 321 is completely located in the avoidance groove 311, When the function of only using the transmission component 33 can be realized, the cutting component 32 is further provided with a fine adjustment mechanism 36, and the fine adjustment mechanism 36 includes a slide plate 361, a fixing plate 362 and a driving member 363. The slide plate 361 is fixedly connected to the driving member 2 322, so when the slide plate 361 is driven to move, the driving member 2 322 and the cutting blade 321 fixedly connected to the driving member 2 322 can be driven to move. Specifically, one side of the slide plate 361 is connected to the mounting plate 363. The plate 31 is slidably connected, and the other side is slidably connected with the fixed plate 362, and the fixed plate 362 is fixedly connected with the frame 1, and the driving member 363 is a structure that can realize the up and down fine-tuning function. In this embodiment, the driving member 363 is a motor, the motor is fixedly connected with the fixed plate 362, and the output end of the motor is fixedly connected with the slide plate 361. When the output end of the motor is driven to move up and down, the slide plate 361 will move up and down to achieve the function of fine-tuning the cutting knife 321. By setting the fine-tuning mechanism 36, not only can a cutting machine of the present invention realize various cutting requirements of circuit boards, such as cutting or only cutting into a "V"-shaped groove or no cutting is required, but also the cutting knife 321 can be moved and stored in the avoidance groove 311 and covered with the groove cover 312 when it is not needed, which can reduce the contact of dust or air with the cutting knife 321 and protect it.

[0058] Furthermore, if Figure 12-13As shown, in order to prevent the machine from malfunctioning during the cutting or conveying process of the circuit board, or the circuit board from shifting and overlapping so that the circuit board is stuck between the two groups of the mounting plates 31 and cannot be removed, a lifting component 34 for driving the mounting plate 31 to move up and down is also provided on the mounting plate 31. One end of the lifting component 34 is fixedly connected to the mounting plate 31, and the other end is fixedly connected to the frame 1. The lifting component 34 is a cylinder 341. The output end of the cylinder 341 is fixedly connected to a top plate 342. The top plate 342 is connected to the fixed The plate 362 is fixedly connected, and the cylinder three 341 is fixedly connected to the mounting plate 31. Since the fixing plate 362 is fixed, when the output end of the cylinder three 341 is driven toward the top plate 342, it will be pressed by the top plate 342 and the fixing plate 362, so that the cylinder three 341 and the mounting plate 31 move downward, and vice versa. That is to say, the mounting plate 31 can be driven up and down by the lifting assembly 34, so that the circuit board therein can be directly taken out, which is also convenient for subsequent inspection and maintenance of the machine.

[0059] Furthermore, if Figure 14-15 As shown, the transmission component 33 includes a driving wheel 331 and a plurality of driven wheels 332, and a transmission belt 333 is wound between the driving wheel 331 and the driven wheels 332; wherein, the mounting plate 31 is also provided with a conveying motor 35 for driving the driving wheel 331 to rotate, and the number of the conveying motors 35 is 2 and they are respectively fixed on the two mounting plates 31 arranged upper and lower, and the output shaft of the conveying motor 35 passes through the mounting plate 31 and is fixedly connected to the two driving wheels 331 arranged on both sides of the mounting plate 31 at the same time, so as to synchronously drive the two transmission components 33 on both sides of the same mounting plate 31, so as to ensure that the transmission speeds of the two transmission components 33 are consistent, so that the transmission is more stable and more conducive to the accuracy of cutting. In addition, the two transmission belts 2 333 with the same upper and lower structures are closely attached to each other and move synchronously, and the circuit board is located between the two transmission belts 2 333. It should be noted that by respectively arranging the transmission components 33 on both sides of the mounting plate 31, the purpose is to form a clamping fixation on both sides of the circuit board. Compared with the single-sided fixation of the prior art, the double-sided fixation of the present invention can further ensure that the circuit board will not be cut off or shifted due to uneven force at the moment of cutting, which not only improves the cutting accuracy, but also reduces the occurrence of faults, thereby making the transmission smoother and more efficient. It should be supplemented that the transmission belt 1 243 and the transmission belt 2 333 in the present invention can be structures such as belts or chains that can be used for transmission.

[0060] Furthermore, if Figure 16-18As shown, the discharging mechanism 4 includes a left conveying component 41 and a right conveying component 42, and the left conveying component 41 and the right conveying component 42 are arranged in parallel, wherein the central axis L1 of the left conveying component 41 forms an angle α with the central axis L2 of the right conveying component 42, and 0°<α<60°, so that the circuit boards conveyed and discharged by the left conveying component 41 and the right conveying component 42 are separated from each other and an offset gap is formed, which can effectively avoid the collision or offset overlap of the two circuit boards after cutting during the conveying process, thereby affecting the conveying effect, and even worse, causing damage to the circuit boards, increasing the occurrence of defective rates, and resulting in increased costs. Specifically, the left conveying component 41 includes an upper left conveying roller 411 and a lower left conveying roller 412, and the upper left conveying roller 411 and the lower left conveying roller 412 correspond to each other up and down to jointly clamp and fix the upper and lower end surfaces of the cut circuit board, which can ensure the stability of the conveying, use fewer parts, have a simple and practical structure, and save costs; the right conveying component 42 includes an upper right conveying roller 421 and a lower right conveying roller 422, wherein one side of the lower right conveying roller 422 is fixedly connected with a driving member 44, and a connecting member 43 is provided between the lower right conveying roller 422 and the lower left conveying roller 412, one end of the connecting member 43 is fixedly connected to the lower left conveying roller 412, and the other end is fixedly connected to the lower right conveying roller 422, and the lower right conveying roller 422 can be driven by the driving member 44 to rotate synchronously with the lower left conveying roller 412 to ensure that the transmission frequency of the two circuit boards is consistent, thereby ensuring the stability of the conveying. It should be noted that, since the central axis L1 of the left conveying component 41 forms an angle α with the central axis L2 of the right conveying component 42, the direction extension line M2 of the circuit board conveyed by the right conveying component 42 is perpendicular to the central axis L2, while the direction extension line M1 of the circuit board conveyed by the left conveying component 41 is consistent with the direction of circuit board transportation, and M1 and M2 intersect.

[0061] The working principle of the present invention is described in detail below:

[0062] During operation, the circuit board to be cut is placed on the loading position 11. Driven by the driving component 24, the first clamping component 21 and the second clamping component 22 will move synchronously toward the loading position 11, and synchronously clamp the circuit boards placed on the loading position 11 and the adjustment position 12, respectively, and then synchronously move toward the cutting position 13. At this time, the conveying components 33 located on both sides of the mounting plate 31 will simultaneously clamp and fix the circuit board clamped by the second clamping component 22. When moving to a certain distance, the cutting knife 321 will synchronously cut, and after the cutting is completed, the The first clamping component 21 and the second clamping component 22 are released at the same time and synchronously move again toward the loading position 11 to continue to convey the next group of circuit boards. During the movement again, the moving adjustment component 5 will simultaneously calibrate the position of the circuit boards clamped by the first clamping component 21 to the adjustment position 12. When the second clamping component 22 moves to the adjustment position 12, the calibration is completed. The second clamping component 22 can clamp the circuit boards again and convey them again without waiting. The cut circuit boards will be promptly transferred out by the left conveying component 41 and the right conveying component 42 of the discharging mechanism 4 respectively.

[0063] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
