[0032] Refer to Figures 1 to 4 As shown, a circuit board cutting device according to an embodiment of the present utility model includes a cutting frame 100 and a cutting mechanism 200.

[0033] Refer to Figure 1 、 Figure 2 and Figure 4As shown, the cutting frame 100 includes a flip plate 110 and a bottom plate 120 which are rotatably connected. The flip plate 110 and the bottom plate 120 can be rotatably connected through a rotating shaft. One end of the rotating shaft is connected to a forward and reverse motor. By driving the forward and reverse rotation of the rotating shaft by the forward and reverse motor, the flip plate 110 can be automatically flipped closer to or away from the bottom plate 120. A cutting hole 111 is provided on the flip plate 110. Correspondingly, a material storage hole 121 is provided on the bottom plate 120. Under the driving action of the forward and reverse motor, the flip plate 110 and the bottom plate 120 can be closed so that the cutting hole 111 can be opposite and communicated with the material storage hole 121. Specifically, both the cutting hole 111 and the material storage hole 121 are square, and the aperture of the cutting hole 111 is smaller than the aperture of the material storage hole 121, so that the finished circuit board cut along the cutting hole 111 can fall into the material storage hole 121.

[0034] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, the circuit board cutting device further includes a cutting mechanism 200. The cutting mechanism 200 is located above the cutting frame 100. The cutting mechanism 200 includes a lifting drive 210, a frame body 220, a transfer assembly 230, a cutting tool 250 and a pressing plate 240. Both the transfer assembly 230 and the pressing plate 240 are connected to the frame body 220. The frame body 220 provides a supporting function for the connection of the transfer assembly 230 and the pressing plate 240. The lifting drive 210 is connected to the frame body 220 to drive the frame body 220 to approach and move away from the cutting frame 100.

[0035] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, when the flip plate 110 is closed relative to the bottom plate 120, the cutting hole 111 can be opposite and communicated with the material storage hole 121. The circuit board to be cut can be placed above the flip plate 110. The lifting drive 210 is connected to the transfer assembly 230 and the pressing plate 240 to drive the transfer assembly 230 and the pressing plate 240 to approach the cutting frame 100, so that the pressing plate 240 can contact the circuit board located on the cutting frame 100 to apply a limiting clamping force to the circuit board, which is beneficial to fixing the relative position of the circuit board on the flip plate 110, reducing the displacement of the circuit board during the cutting process, and improving the cutting accuracy of the circuit board.

[0036] Refer to Figure 1 、 Figure 2 and Figure 3As shown, the transfer assembly 230 is drivingly connected to the cutting knife 250 to drive the cutting knife 250 to cut along the cutting hole 111, so that the circuit board is cut according to the shape of the preset cutting hole 111. After cutting, the circuit board falls into the storage hole 121. Then, the lifting drive 210 drives the transfer assembly 230 and the pressing plate 240 away from the cutting frame 100, so that the pressing plate 240 is separated from the circuit board on the cutting frame 100. By the flipping away of the flipping plate 110 and the bottom plate 120, the separation of the waste board and the finished product can be realized. Through the cooperation of the lifting drive 210 and the pressing plate 240, the circuit board cutting device can automatically realize the limiting and clamping of the circuit board, which is beneficial to improving the cutting accuracy of the circuit board. Moreover, the transfer assembly 230 and the pressing plate 240 share one lifting drive 210 to realize the movement in the up and down directions, which is beneficial to reducing the manufacturing cost of the circuit board cutting device.

[0037] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, it should be noted that when it is necessary to change the size of the cut circuit board, the movement stroke of the cutting knife 250 driven by the transfer assembly 230 can be controlled by programming and controlling the transfer assembly 230, or by replacing the flipping plate 110 with different specifications of cutting holes 111.

[0038] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, it can be understood that the cutting mechanism 200 further includes an elastic member 260 and a guide post 270. The guide post 270 is provided with a guide hole. The lower end of the guide post 270 is connected to the pressing plate 240, and the upper end of the guide post 270 passes through the guide hole. Through the mutual abutment of the guide hole and the guide post 270, the guide post 270 can slide up and down along the guide hole, that is, the guiding of the up and down movement of the pressing plate 240 is realized.

[0039] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, specifically, the elastic member 260 is a spring. The two ends of the spring are respectively connected to the pressing plate 240 and the frame body 220. Each pressing plate 240 is correspondingly provided with at least two guide posts 270 and at least two guide holes. Through the mutual limitation of the multiple guide posts 270 and the guide holes, it is beneficial to enhance the stability of the up and down movement of the pressing plate 240 relative to the frame body 220. A spring is sleeved on each guide post 270. The spring is sleeved outside the guide post 270, and the lower end of the spring abuts against the upper end of the pressing plate 240, and the upper end of the spring abuts against the lower end of the frame body 220.

[0040] Referring to Figure 1 、 Figure 3 and Figure 4As shown, in the natural state, the lower end of the pressing plate 240 is located below the lower end of the cutting tool 250. Under the driving action of the lifting drive 210, the pressing plate 240 and the cutting tool 250 descend simultaneously. Since the lower end of the pressing plate 240 is located below the lower end of the cutting tool 250, the pressing plate 240 first abuts against the circuit board on the cutting frame 100. With the driving action of the lifting drive 210, the pressing plate 240 can compress the elastic member 260, causing the guide post 270 to slide along the guide hole. Under the elastic action of the elastic member 260, the pressing plate 240 applies a limiting clamping force to the circuit board located on the cutting frame 100, which is beneficial to fixing the relative positional relationship of the circuit board on the cutting frame 100. With the continuous driving of the lifting drive 210, the cutting tool 250 can be brought into contact with the circuit board, thereby realizing the cutting of the circuit board. Under the transfer action of the transfer assembly 230, the cutting tool 250 can be moved along the edge of the cutting hole 111, so that the circuit board is cut according to the preset cutting hole 111. The cut finished product can pass through the cutting hole 111 and fall into the stock hole 121, thereby realizing the separation of the finished product and the waste board.

[0041] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, when the circuit board cutting is completed, the lifting drive 210 drives the frame body 220 to move away from the cutting frame 100. At this time, the cutting tool 250 first separates from the waste board. With the elastic force released by the elastic member 260, the pressing plate 240 remains in contact with the waste board, that is, the pressing plate 240 separates from the waste board after the cutting tool 250, which is beneficial to fixing the relative positional relationship of the waste board on the cutting frame 100. When the pressing plate 240 is completely separated from the waste board, under the driving action of the forward and reverse drive motor, the flipping plate 110 and the bottom plate 120 flip away from each other, so that the waste board located on the flipping plate 110 flips away with the flipping plate 110, thereby realizing the flipping and discharging of the waste board.

[0042] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, it can be understood that multiple elastic members 260, multiple guide posts 270 and the pressing plate 240 together form a pressing component. Multiple pressing components are provided, and the multiple pressing components are arranged around the transfer assembly 230.

[0043] Referring to Figure 1 、 Figure 3 and Figure 4 As shown, that is, the circuit board cutting device realizes multi-point limiting and pressing of the circuit board through multiple pressing components, which is beneficial to fixing the relative positional relationship of the circuit board on the cutting frame 100.

[0044] Referring to Figure 1 、 Figure 2 and Figure 3As shown in the figure, specifically, the circuit board cutting device has four pressing components that together form a square frame, and the transfer assembly 230 is disposed within the square frame. Under the driving action of the lifting drive 210, the pressing plate 240 and the cutting tool 250 descend simultaneously. Since the lower end of the pressing plate 240 is located below the lower end of the cutting tool 250, the four pressing plates 240 first come into contact with the circuit board on the cutting frame 100. With the driving action of the lifting drive 210, the four pressing plates 240 can compress the elastic member 260, causing the guide post 270 to slide along the guide hole. Under the elastic action of the elastic member 260, the multiple pressing plates 240 can apply a multi-point limiting clamping force to the circuit board located on the cutting frame 100, which is beneficial to fixing the relative positional relationship of the circuit board on the cutting frame 100.

[0045] Referring to Figure 1 , Figure 2 and Figure 3 As shown, with the continuous driving of the lifting drive 210, the cutting tool 250 can be brought into contact with the circuit board, thereby achieving the cutting of the circuit board. Under the transfer action of the transfer assembly 230, the cutting tool 250 can move along the edge of the cutting hole 111, so that the circuit board is cut according to the preset cutting hole 111. The circuit board cutting device is provided with multiple pressing components, which is beneficial to restricting the displacement of the circuit board in the length and width directions of the cutting hole 111, and is beneficial to improving the cutting accuracy of the circuit board. The cut finished product can pass through the cutting hole 111 and fall into the storage hole 121, thereby realizing the separation of the finished product and the waste board.

[0046] Referring to Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that considering that the cutting direction of the cutting tool 250 needs to be changed when the cutting tool 250 cuts along the edge of the cutting hole 111, the cutting mechanism 200 provided by the embodiment of the present invention further includes a corner drive 280 and a rotation drive 290. Both the rotation drive 290 and the transfer assembly 230 are connected to the corner drive 280. The corner drive 280 is used to drive the rotation drive 290 to swing relative to the transfer assembly 230, and the rotation drive 290 is connected to the transfer assembly 230. The rotation drive 290 is in transmission connection with the cutting tool 250 to drive the cutting tool 250 to rotate.

[0047] For example, after the cutter 250 finishes cutting along the length direction of the cutting hole 111, the subsequent cutter 250 needs to cut along the width direction of the cutting hole 111. The circuit board cutting device can drive the rotation drive 290 to swing relative to the transfer assembly 230 through the operation of the corner drive 280, so as to change the cutting direction of the cutting edge of the cutter 250, make the cutting edge of the cutter 250 parallel to the width direction of the cutting hole 111. Under the transfer action of the transfer assembly 230, the cutter 250 can be made to closely adhere to the width edge of the cutting hole 111. Then, the rotation drive 290 drives the cutter 250 to rotate. After the cutter 250 abuts against the circuit board, the cutting function of the circuit board can be realized.

[0048] It should be noted that both the rotation drive and the rotation drive 290 can be set as servo drive motors. Under the driving action of the servo drive motors, the accurate swing of the rotation drive 290 relative to the transfer assembly 230 and the accurate control of the cutter 250 can be realized.

[0049] Refer to Figure 1 、 Figure 2 and Figure 4 As shown, it can be understood that the transfer assembly 230 includes two groups of linear drives 231 connected to each other, and the driving directions of the two groups of linear drives 231 are arranged at right angles.

[0050] Refer to Figure 1 、 Figure 2 and Figure 4 As shown, specifically, the linear drive 231 includes a slide rail, a rack, a gear, a slider and a motor. The rack is connected to the slide rail, the slider is slidably connected to the slide rail, the gear is rotatably connected to the slider, the gear is meshed with the rack for transmission, and the motor is connected to the gear for transmission to drive the gear to rotate forward or backward.

[0051] Refer to Figure 1 、 Figure 2 and Figure 4 As shown, that is, the linear drive 231 is a rack and pinion drive mechanism, and the linear reciprocating sliding of the slider relative to the slide rail is driven by the meshing connection of the gear and the rack.

[0052] Refer to Figure 1 、 Figure 2 and Figure 4 As shown, taking the two groups of linear drives 231 named the first linear drive 231 and the second linear drive 231 as examples for illustration, the driving direction of the first linear drive 231 is the left-right direction, and the driving direction of the second linear drive 231 is the front-back direction as an example for illustration.

[0053] ​​​​​​The slide rail of the second linear drive 231 is connected to the slider of the first linear drive 231. The first linear drive 231 can drive the slider to make a reciprocating linear movement in the left - right direction along the slide rail. The slide rail of the second linear drive 231 is connected to the slider of the first linear drive 231 so that the slide rail of the second linear drive 231 synchronously makes a reciprocating linear movement in the left - right direction. The linear drive 231 of the second linear drive 231 can drive the slider to make a reciprocating linear movement in the front - back direction along the slide rail extending in the front - back direction. The corner drive 280 and the rotary drive 290 are both connected to the slider of the second linear drive 231, that is, the movement of the corner drive 280 and the rotary drive 290 in the left - right direction and the front - back direction is realized. With the driving effect of the angular swing of the corner drive 280 and the driving effect of the rotary drive 290 on the rotation of the cutting tool 250, the cutting tool 250 can cut along the edge of the cutting hole 111, so as to realize the cutting function of the finished circuit board.

[0054] It should be understood that the two sets of linear drives 231, corner drives 280, rotary drives 290 and cutting tools 250 together form a set of cutting components. The circuit board cutting device is provided with two sets of cutting components corresponding to each cutting hole 111. The two sets of cutting components jointly cut the circuit board at one cutting hole 111, that is, the two cutting tools 250 cut the circuit board synchronously, which is beneficial to improving the cutting efficiency of the circuit board and avoiding the problem that the connecting edge between the finished circuit board and the waste board is too short, resulting in the bending of the circuit board.

[0055] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, it can be understood that the circuit board cutting device further includes a collecting plate 300, a filter and a blower. The collecting plate 300 is arranged below the cutting frame 100, and the collecting plate 300 is provided with a collecting groove opening upward. The covering area of the collecting groove is larger than the covering area of the cutting frame 100. The collecting groove is provided with a plurality of collecting holes 310. The collecting holes 310 can be connected to the filter through a pipeline, and the filter can be connected to the blower through a pipeline.

[0056] Refer to Figure 1 、 Figure 2 and Figure 3 As shown, when cutting the circuit board, the waste generated along the cutting edge of the circuit board can fall into the covering area of the collecting groove. Under the driving action of the blower, the wind energy of the blower passes through the filter plate and the collecting holes 310, so that a negative pressure is generated at the collecting holes 310, thus realizing the collection of the waste generated by cutting the circuit board, which is beneficial to avoiding the problem that the waste splashes everywhere, causing pollution to other circuit boards or damaging the personal safety of the workers in the workshop.

[0057] It should be noted that the filter plate is provided with filter units such as sponges inside, and the structure of the filter plate belongs to the prior art, so it will not be elaborated here.

[0058] Referring to Figure 1 , Figure 2 and Figure 4 As shown, it can be understood that considering the damage caused by the waste generated during the circuit board cutting to the workshop environment or the personnel in the workshop, the circuit board cutting device further includes a cover body, which covers the outside of the cutting mechanism 200 and the cutting frame 100, so that the waste generated during the circuit board cutting is concentrated in the cover body, which is beneficial to avoiding the problem that the waste splashes around the workshop and causes pollution to other circuit boards or damage to the personal safety of the workers in the workshop.

[0059] Referring to Figure 1 , Figure 2 and Figure 4 As shown, specifically, a door body is movably connected to the cover body. Through the movable connection between the door body and the cover body, the internal cavity of the cover body can be opened or closed. When the door body is opened relative to the cover body, a passage for personnel to enter and exit can be formed, so as to facilitate personnel to enter and exit the internal cavity of the cover body, and thus replace or repair the cutting mechanism 200 or the cutting frame 100 located in the cover body.

[0060] Referring to Figure 1 , Figure 3 and Figure 4 As shown, it can be understood that the cutting frame 100 further includes a cylinder, a vibration motor 410 and a supporting plate 420. The cylinder is connected to the vibration motor 410, the vibration motor 410 is connected to the supporting plate 420, and the supporting plate 420 is placed in the material storage hole 121.

[0061] Referring to Figure 1 , Figure 3 and Figure 4 As shown, after the circuit board is cut on the cutting frame 100, the cut finished product passes through the cutting hole 111 and falls into the material storage hole 121 and lands on the upper end of the supporting plate 420. The vibration motor 410 is connected to the vibration plate, which is beneficial to shaking off the waste on the surface of the finished product, so that the waste can fall into the collection groove of the collection plate 300 to realize the collection of the waste.

[0062] Referring to Figure 1 , Figure 3 and Figure 4 As shown, when the circuit board finished product supported on the supporting plate 420 reaches the preset weight or thickness, the cylinder can drive the supporting plate 420 to rise or fall, so that the supporting plate 420 and the circuit board finished product exit the material storage hole 121, so as to facilitate the worker or the external clamping mechanism to move the stacked circuit board finished products out of the cutting frame 100 to realize the handling of the circuit board finished products.
