Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cutting, in particular to a circuit board cutting device with high accuracy. Background Art

[0002] Cutting machines are indispensable equipment for some light industries. Traditionally, cutting machines are machines that use the force of machine movement to pressurize the die to cut materials. Modern cutting machines have undergone some changes, and advanced technologies such as high-pressure water jets and ultrasound have begun to be used in leather punching technology, but people still classify these devices as cutting machines. In the production process of circuit boards, copper clad laminates, one of the raw materials, need to be cut. A whole copper clad laminate is divided into plates of different sizes and shapes according to design requirements, and then enters the subsequent processing steps.

[0003] The publication number is CN215698531U. The Chinese patent discloses a fully automatic cutting machine for circuit board processing, which includes a carrier, a conveyor belt is installed on one side of the top of the carrier, and a clamping mechanism with a spacing adjustment structure is installed on the conveyor belt to adaptively clamp and fix the circuit board when cutting. A cutting mechanism is provided on the outer side of the carrier. When the utility model uses the clamping mechanism for clamping, the slide has a certain moving space, so that the clamping mechanism can adapt to the clamping of copper clad boards of different sizes within a certain range, and the T-shaped clamping plate makes the active end in the clamping structure a plane rather than a point, that is, the contact area between the copper clad board and the clamping plate is sufficient to strengthen the clamping effect. In addition, after the cutting is completed, it is only necessary to start the conveyor belt, and the U-shaped frame structure formed by the clamping plate and the vertical plate can stably push the copper clad board into the receiving component.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, when operating the clamping mechanism to clamp the copper clad laminate, it is necessary to manually turn the handle to finally achieve the clamping and fixing of the copper clad laminate by the clamping plate. The operating positions of the two handles are far apart, which is inconvenient for the staff to quickly assemble and disassemble the copper clad laminate, and has poor practicality. Therefore, it is necessary to provide a circuit board cutting device with high accuracy to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a circuit board cutting device with high accuracy to solve at least one technical problem existing in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

A transmission mechanism is arranged between the two adjusting screws, and a motor is fixedly installed in front of the other side of the processing table, and the motor is fixedly connected to the other end of an adjusting screw, and sliders are sleeved on the outer walls of the two adjusting screws, and the two sliders are symmetrically distributed and fixedly installed on the inner surface of the gantry.

[0012] Preferably, a through slot is opened on one side of the fixed block at the top of the cutting platform, a limit plate is slidably inserted inside the through slot, a first electric telescopic rod is fixedly installed at the bottom of the limit plate, and the bottom end of the first electric telescopic rod is fixedly connected to the top of the processing table.

[0013] Preferably, the transmission mechanism is composed of a driving wheel, a driven wheel and a belt, and the driving wheel and the driven wheel are connected by belt transmission, and the driving wheel and the driven wheel are respectively fixedly sleeved on the outer wall of one end of the two adjusting screw rods.

[0014] Preferably, a threaded hole matched with the adjusting screw is opened on one side of the slider, and the slider is threadedly connected to the adjusting screw through the threaded hole opened on one side.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model cooperates with a processing table, a support plate, a transmission mechanism, a support block, a first electric telescopic rod, a through groove, a limit plate, a gantry, a cutting platform, a slideway, an adjusting screw rod, a motor, a slider, a cutting head, a longitudinal vertical linear motion platform, a clamping plate, a second electric telescopic rod and a fixed block. When clamping and limiting the copper clad laminate before cutting, the two clamping plates are driven by the two second electric telescopic rods to move relative to each other, so that the copper clad laminate between the two can be clamped quickly. When the two clamping plates move in opposite directions, the clamping effect on the copper clad laminate will be quickly lost. Compared with the existing manual adjustment and fixation, the utility model is more convenient and accurate, ensures accurate cutting of the copper clad laminate, and is convenient for rapid assembly and disassembly of the copper clad laminate.

During the movement of the push plate, the cut copper clad laminate is directly pushed to the top of the collecting table. Because the collecting table is directly placed on the top of the support column, one side of the collecting table and one side of the cutting platform can be seamlessly connected. The push plate can be moved to the top of the collecting table and push the cut copper clad laminate directly to its top position. During the pushing process, the push plate is pushed forward at a uniform speed by relying on the lateral moving mechanism, and the seamless connection between the side of the collecting table and the side of the cutting platform can ensure that the relative position of the copper clad laminate pushed to the top of the collecting table remains unchanged, avoiding chaotic stacking of the copper clad laminates. The collecting table and the copper clad laminate can be directly taken away together, so that the staff can intuitively take copper clad laminates of different shapes according to needs, while also realizing the versatility of the lateral moving mechanism.

[0032] In one embodiment, the lateral movement mechanism includes a slide 12, and the number of the slides 12 is two, the two slides 12 are symmetrically distributed and are respectively opened on the front and back sides of the processing table 1, and the insides of the two slides 12 are rotatably installed with adjustment screws 13, and one end of the adjustment screw 13 passes through one side of the inner wall of the slide 12 and extends to one side of the processing table 1, and a transmission mechanism 3 is arranged between the two adjustment screws 13, and the transmission mechanism 3 is located on one side of the processing table 1, and the other end of one adjustment screw 13 passes through the other side of the inner wall of one slide 12 and extends to the processing table 1 On the other side, a motor 16 is fixedly installed in front of the other side of the processing table 1, and the motor 16 is fixedly connected to the other end of an adjusting screw rod 13, and sliders 17 are sleeved on the outer walls of the two adjusting screw rods 13, and the sliders 17 are slidably connected to the slideway 12. The two sliders 17 are symmetrically distributed and fixedly installed on the inner surface of the gantry 10, realizing the horizontal movement of the cutting head 18. In conjunction with the longitudinal vertical linear motion platform 19, during the cutting process of the copper clad laminate, there is no need to move the position of the copper clad laminate, and the cutting accuracy of the copper clad laminate can be improved.

[0033] In one of the preferred embodiments, a through groove 6 is provided on one side of the fixed block 22 at the top of the cutting platform 11, and a limit plate 8 is slidably inserted inside the through groove 6.

[0036] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to the power supply and the controller when in use, the raw material of the circuit board, that is, the copper-clad board, is placed on the top of the cutting platform 11, and at the same time, the first electric telescopic rod 5 is controlled to start working, and the driving end of the first electric telescopic rod 5 drives the limit plate 8 to move vertically, so that the limit plate 8 moves upward and moves to the top of the cutting platform 11, and then pushes the copper-clad board so that the side of the copper-clad board is squeezed and contacted with the side of the limit plate 8, which has the effect of pre-positioning the copper-clad board, and then the two second electric telescopic rods 21 are controlled to start working, and the driving end of the second electric telescopic rod 21 drives the two second electric telescopic rods 21 to move relative to each other, clamps and limits the copper-clad board placed therebetween, and then splits and cuts the material, and the vertical and longitudinal movement of the cutting head 18 can be realized through the longitudinal vertical linear motion platform 19, and at the same time, the motor 16 is controlled to work, so that the driving end of the motor 16 drives the adjusting screw 13 in front of the processing table 1 to rotate, and the two adjusting screws 13 are rotated at the same time through the transmission of the transmission mechanism 3, and when the adjusting screw 13 and the slider 1 7, and the sliding relationship between the slider 17 and the slideway 12 makes the two sliders 17 move horizontally synchronously, the movement of the slider 17 drives the gantry 10 to move, and the movement of the gantry 10 drives the cutting head 18 to move horizontally through the longitudinal vertical linear motion platform 19. Therefore, under the cooperation of the motor 16 and the longitudinal vertical linear motion platform 19, the cutting head 18 can be moved horizontally, vertically and longitudinally within a specified range, and the copper clad laminate is cut at a specific position according to the pre-designed circuit design to complete the cutting. When clamping and limiting the copper clad laminate before cutting, the two second electric telescopic rods 21 drive the relative movement of the two clamping plates 20, so that the copper clad laminate between the two can be quickly clamped. When the two clamping plates 20 move in opposite directions, the clamping effect on the copper clad laminate will be quickly lost. Compared with the existing manual adjustment and fixation, it is more convenient and accurate, ensuring the accurate cutting of the copper clad laminate and facilitating the rapid assembly and disassembly of the copper clad laminate. At the same time, the mobility of the two clamping plates 20 facilitates the clamping and limiting of copper clad laminates of different sizes, and is highly practical.

[0037] After the copper clad laminate is cut, the two clamping plates 20 are moved in opposite directions, the copper clad laminate is lost, and the driving end of the first electric telescopic rod 5 is controlled by the switch to drive the limit plate 8 to reset, so that the top of the limit plate 8 is flush with the top of the processing table 1. At the same time, the gantry 10 is moved horizontally by controlling the horizontal movement mechanism. The movement of the gantry 10 drives the push plate 7 to move through the fixed frame 9, so that the push plate 7 approaches the collecting table 14 at a uniform speed. During the movement, the push plate 7 will directly push the cut copper clad laminate to the top of the collecting table 14. Because the collecting table 14 is directly placed on the top of the support column 15, the collecting table 14 can be easily moved. One side of the platform 14 can be seamlessly connected with one side of the cutting platform 11, and the push plate 7 can be moved to the top of the collecting platform 14 and push the cut copper clad laminate directly to its top position. During the pushing process, the push plate 7 is pushed forward at a uniform speed by relying on the lateral moving mechanism. In addition, the side of the collecting platform 14 and the side of the cutting platform 11 are seamlessly connected, which can ensure that the relative position of the copper clad laminate pushed to the top of the collecting platform 14 remains unchanged, avoiding chaotic stacking of the copper clad laminates. The collecting platform 14 and the copper clad laminates can be directly taken away together, so that the staff can intuitively take copper clad laminates of different shapes according to their needs, while also realizing the versatility of the lateral moving mechanism.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
