[0002] PCB soft board, also known as flexible printed circuit board (FPC), is a thin and flexible circuit board. It is usually used in mobile electronic devices, medical electronic devices and other use environments with high precision and bending requirements.

[0003] During the processing of FPC, it is necessary to perform precise shape cutting according to the layout of the circuit design, which makes the shape of FPC very irregular and has extremely high requirements for cutting accuracy. Therefore, the most commonly used cutting method is laser cutting.

[0004] After using laser cutting to cut FPC, when taking out the FPC target, the FPC target needs to be separated from the waste. Due to the complex shape of FPC, some waste may be disconnected from the main part due to cutting restrictions and cannot be taken away with most of the waste. As a result, this step usually requires manual careful identification and manual removal of these isolated wastes, which undoubtedly greatly prolongs the waste processing time and affects the overall processing efficiency of FPC.

[0061] The cover frame 1102 also includes: a control machine 12 fixedly mounted on the bottom frame 1101, the control machine 12 is located at the inner rear side of the cover frame 1102; a laser cutting head 13 mounted on the control machine 12, the laser cutting head 13 is used for laser cutting of the FPC, the control machine 12 controls the laser cutting head 13 to move along the shape of the FPC according to the data, so as to achieve precise cutting; an installation frame A14 fixedly mounted on the top of the bottom frame 1101, the installation openings 1105 are located on both sides of the installation frame A14; a laser cutting head 13 is mounted on the cover frame 1102 through a rotating shaft. The slitting plate 15 on the mounting frame A14 is located below the laser slitting head 13, and the FPC will be placed on the slitting plate 15 for laser slitting; the placement plates 16 are fixedly mounted on the left and right sides of the top of the bottom frame 1101, and the two placement plates 16 are respectively used to place the FPC to be slit and the FPC target object that has completed slitting, and the two placement plates 16 are respectively located near the side walls of the cover frame 1102, so that the FPC can be easily taken and placed on the placement plate 16 through the take-and-place port 1104 through the cover frame 1102.

[0065] Combination Figure 6-Figure 7 As shown, the moving member 31 includes: a mounting block A3101 fixedly mounted on the front and rear sides of the mounting frame A14; a guide rod A3102 fixedly mounted on the mounting block A3101 on the front and rear sides respectively; a screw rod A3103 rotatably mounted on the mounting block A3101 on the front and rear sides respectively, the guide rod A3102 and the screw rod A3103 on the same side of the front and rear are a combination, and two moving blocks 32 are respectively arranged on the combination of two groups of guide rods A3102 and screw rod A3103, the moving block 32 is threadedly mounted on the screw rod A3103, and is slidably mounted on the guide rod A3102, therefore, the screw rod A3103 rotates forwards and backwards to control the moving block 32 to move left and right; a transmission belt group A3104 is installed between the two screw rods A3103, and the transmission belt group A3104 enables the two screw rods A3103 to rotate synchronously.

[0066] Combination Figure 3 and Figure 8As shown, it also includes: a moving mechanism 41 installed on the mounting plate 21, a material-retrieving mechanism 22 installed on the moving mechanism 41, and thus controlled to move by the moving mechanism 41, and two groups of material-retrieving mechanisms 22 are arranged on the moving mechanism 41, and the two groups of material-retrieving mechanisms 22 will be controlled to move synchronously, but they move back and forth between the placement plate 16 and the slitting plate 15 on the left, and between the slitting plate 15 and the placement plate 16 on the right, respectively. The moving mechanism 41 includes: a mounting block B4101 fixedly mounted on the bottom of the mounting plate 21; two guide rods B4102 fixedly mounted on the mounting block B4101; two screws B4103 rotatably mounted on the mounting block B4101; and a mounting block B4101 fixedly mounted on the mounting block B4101. The motor 4104 has an output end fixed to one of the screws B4103; a transmission belt group B4105 installed between the two screws B4103, and the transmission belt group B4105 makes the two screws B4103 rotate synchronously; a connecting plate 4106 is provided between the screw B4103 and the guide rod B4102, and the connecting plate 4106 is slidably installed with the guide rod B4102 and threadedly installed with the screw B4103.

There are two connecting plates 4106 in total, and the electric rods A2201 of the two sets of feeding mechanisms 22 are respectively detachably fixed on the two connecting plates 4106.

[0067] Combination Figure 8 As shown, it also includes: a transmission belt group C42 installed between one of the screws A3103 and one of the screws B4103, and the frequency of the reciprocating movement of the moving block 32 controlled by the screw A3103 will be consistent with the frequency of the reciprocating movement of the connecting plate 4106 controlled by the screw B4103.

[0068] Motor 4104 is used to provide power for the movement of the moving block 32 and the material picking mechanism 22, and the transmission belt group C42 will keep the operation coordination between the two stable: when the moving block 32 moves to control the rotation of the slitting plate 15, the material picking mechanism 22 is still in the process of moving, and when the material picking mechanism 22 completes the movement, the slitting plate 15 will also complete the rotation synchronously.

[0069] Combination Figure 9-11As shown, it also includes: a mounting frame B51 fixedly mounted on the front and rear sides of the bottom of the mounting frame A14; a scraper strip 52 slidably mounted between the two mounting frames B51, the scraper strip 52 is located below the slitting plate 15 and can contact the slitting plate 15; a return spring A53 sleeved on the mounting frame B51, one end of the return spring A53 is fixed to the mounting frame B51, and the other end is fixed to the scraper strip 52, the return spring A53 makes the scraper strip 52 located at the lower right position of the slitting plate 15 under natural conditions, and does not contact the slitting plate 15 to prevent it from affecting the rotation of the slitting plate 15; a top block A54 fixedly mounted on the two moving blocks 32 respectively, and the top block A54 is set to a bracket type; The inclined surface block 55 is movably installed on the front and rear ends of the scraper strip 52, and the inclined surface of the inclined surface block 55 is set to the left. When the top block A54 contacts the inclined surface of the inclined surface block 55, the top block A54 will squeeze the inclined surface block 55 to move in the direction of the scraper strip 52, and when the top block A54 contacts the non-inclined surface of the inclined surface block 55, the top block A54 will be able to hook with the inclined surface block 55; a return spring B56 is sleeved on the inclined surface block 55, one end of the return spring B56 is fixed to the inclined surface block 55, and the other end is fixed to the scraper strip 52; the extrusion block 57 is fixedly installed on the front and rear sides of the lower left part of the installation frame A14, and the extrusion block 57 can contact the inclined surface of the inclined surface block 55 and squeeze the inclined surface block 55 to move in the direction of the scraper strip 52.

[0070] When the moving block 32 moves to the right, the two top blocks A54 will move to contact the two inclined plane blocks 55 respectively. During this process, the top block A54 will squeeze the inclined plane block 55 to move, and the return spring B56 will be compressed, so that the top block A54 passes over the inclined plane block 55 and moves to the right side of the inclined plane block 55. Subsequently, the inclined plane block 55 is reset by the return spring B56. Afterwards, when the moving block 32 moves to the left, the top block A54 located on the right side will be able to contact the non-inclined surface of the inclined plane block 55, and the moving block The moving block 32 can drive the scraper 52 to move to the left together through the cooperation of the top block A54 and the inclined block 55, and the return spring A53 is compressed, so that the scraper 52 cleans the FPC remaining on the slitting plate 15; and when the moving block 32 moves to the left until the inclined block 55 contacts the extrusion block 57, the extrusion block 57 will squeeze the inclined block 55 to move, so that the inclined block 55 is separated from the top block A54, and the return spring A53 can quickly reset the scraper 52 to the right to prevent the scraper 52 from affecting the rotation of the slitting plate 15. In summary, when the moving block 32 moves to the right, the slitting plate 15 will be controlled to rotate 180 degrees; when the moving block 32 moves to the left, the slitting plate 15 is not rotated, and the scraper 52 is driven to move to the left to scrape off the residual waste on the side of the slitting plate 15 that is rotated to the bottom; when the scraper 52 moves to the left position and completes the cleaning work, the scraper 52 will be unlocked by the extrusion block 57 and quickly reset to the right.

[0071] Combination Figure 12-13As shown, it also includes: a corrugated frame 61 fixedly mounted on the right part of the inner front side wall of the cover frame 1102; a top block B62 fixedly mounted on the front side of the mounting frame 2204, and the movable material-picking mechanism 22 will make the top block B62 contact with the corrugated frame 61 and produce extrusion; a sliding frame 63 fixedly mounted on the central controller 2203, and the central controller 2203 is slidably mounted with the mounting portion 2202 through the sliding frame 63; a return spring C64 mounted on the sliding frame 63, and one end of the return spring C64 is fixed to the sliding frame 63, and the other end is fixed to the mounting portion 2202.

[0072] When the picking mechanism 22 adsorbs the FPC target object for discharging, the corrugated frame 61 will contact the top block B62 and squeeze the mounting frame 2204 and other components to move, and then the reset spring C64 will quickly reset it, so that the mounting frame 2204 will vibrate, so as to separate the FPC target object from the waste material not adsorbed by the suction cup 2206 through vibration.

[0073] Before using the slitting device, the following operations need to be performed:

[0074] (1) Place a batch of FPCs to be cut on the placement plate 16 on the left;

[0075] (2) Replacing the material taking mechanism 22 with the appropriate precision according to the size and fineness of the FPC target object;

[0076] (3) Inputting the shape data of the FPC raw material and the shape data of the FPC target object into the control machine 12;

[0077] After completion, the slitting device can be started to perform FPC slitting processing. For ease of description, the following will describe the FPC in the middle process of the slitting device, rather than the first and last FPCs to be slitting.

[0078] First, the electric rod B2205 controls the suction cup 2206 to move downward, and each suction cup 2206 is adjusted to the shape of the FPC target object, wherein the left-side material picking mechanism 22 is controlled according to the input shape data of the FPC raw material, and the right-side material picking mechanism 22 is controlled according to the input shape data of the FPC target object; after completion, the electric rod A2201 controls the suction cup 2206 to move downward as a whole, controls this part of the suction cup 2206 that has been moved downward in advance to contact with the FPC, and at the same time, the air press 2207 operates to make this part of the suction cup 2206 adsorb and fix the FPC, so that the movable material picking mechanism 22 can move and transport the FPC.

[0079] When the two sets of material picking mechanisms 22 move to the right, the FPC raw material to be cut will be moved from above the left placement plate 16 to above the slitting plate 15, and the FPC target object that has been cut will be moved from above the slitting plate 15 to above the right placement plate 16; after completion, the electric rod A2201 moves the FPC down, and the air compressor 2207 releases the pressure, so that the FPC to be cut is loaded onto the slitting plate 15, and the FPC target object that has been cut is unloaded onto the right placement plate 16, that is, the loading and unloading steps in the FPC cutting process are completed at the same time.

[0080] At the same time, in the process of the above-mentioned two groups of material-retrieving mechanisms 22 moving to the right, the transmission screw B4103 of the transmission belt group C42 rotates, so that the moving member 31 can synchronously control the moving block 32 to move to the right, thereby controlling the slitting plate 15 to rotate 180 degrees, and rotating the remaining waste of the FPC that has completed slitting to the bottom, so that most of the waste can fall into the frame in the bottom frame 1101 for unified collection, and the moving block 32 moves the top block A54 to the right side of the inclined block 55, so that the moving block 32 is hooked with the scraper 52; and at the same time, the material-retrieving mechanism 22 on the right side is vibrated by the corrugated frame 61, because the waste is not adsorbed by the suction cup 2206, therefore, the waste that may be attached to the FPC target object can be shaken off in the vibrating state, ensuring the comprehensive separation of the FPC target object and the waste, and the falling waste will fall into the frame.

[0081] After completing the above actions, a new FPC to be processed is added to the slitting plate 15. Therefore, after the two sets of material-feeding mechanisms 22 move up, the control machine 12 can control the laser slitting head 13 to slit the FPC raw material. Then, after the FPC is slit, the two sets of material-feeding mechanisms 22 move to the left first, and then repeat all the above operations to unload the FPC and add the next FPC to the slitting plate 15. This cycle is repeated to realize the automatic slitting processing of the FPC by the slitting device.

[0082] When the material taking mechanism 22 moves to the left, the slitting plate 15 will not be rotated, and the scraper 52 is driven to move to the left at this time. Therefore, the scraper 52 can clean the waste that may remain on the slitting plate 15 to prevent the waste from remaining and affecting the use of the slitting plate 15, and prevent the subsequent FPC slitting effect and quality from being affected. Subsequently, the scraper is released by the squeezing block 57 and quickly returns to its position; all the waste will be collected in the frame, and finally the frame can be taken out for unified treatment.
