Description

Technical Field

[0001] The utility model relates to the field of printed circuit board manufacturing, and particularly relates to a blanking device for the etching process of a printed circuit board. Background Art

[0002] Printed circuit board etching is a key process for manufacturing circuit boards. The main purpose is to chemically remove the unnecessary copper layers on the copper clad laminate to form conductive paths and patterns on the circuit board. After the printed circuit board is etched, it needs to be processed, such as stripping the film, stripping the tin, cleaning, drying, etc.

[0003] In many existing circuit board manufacturing production lines, the etching process of the circuit board and the subsequent processing processes are separated and non - continuous production line operations. This requires transferring the etched circuit boards to the subsequent production lines. Usually, a blanking device is used to blank the circuit boards at the outlet of the etching equipment onto a small trolley, and the small trolley transports the etched circuit boards to the subsequent production lines. Existing blanking devices usually use manipulators, which have complex structures, high costs, and also require a high degree of professionalism in debugging. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a blanking device for the etching process of a printed circuit board to solve the above - mentioned technical problems.

[0005] According to one aspect of the utility model, a blanking device for the etching process of a printed circuit board is provided, including:

[0006] A conveying part, the conveying part includes a plurality of rollers arranged in parallel;

[0007] A bearing platform, the bearing platform is arranged at the side of the conveying part and is lower than the rollers;

[0008] A blanking member, the blanking member is used to transfer the circuit board on the roller to the bearing platform;

[0009] A rotating shaft, the blanking member is fixedly arranged on the rotating shaft; and

[0010] A driving device, the driving device drives the rotating shaft to rotate so that the blanking member transfers the circuit board on the roller to the bearing platform.

[0011] The conveying part of the unloading device of the printed circuit board etching process of the utility model is installed at the outlet end of the etching equipment, and the roller can convey the etched circuit board delivered from the outlet end of the etching equipment. Under the action of the driving device, the rotating shaft drives the unloading piece to flip, and the rotating roller can convey the etched circuit board to the unloading piece, and then under the action of the driving device, the rotating shaft drives the unloading piece to flip in the opposite direction, and the unloading piece flipped in the opposite direction can transfer the circuit board to the supporting table. The unloading device of the utility model can transfer the etched circuit board on the roller to the supporting table by driving the unloading piece to flip and flip in the opposite direction through the driving device. The structure is simple and the cost is low. It only needs to set the working mode of the driving device in advance. The conveying part can be the conveying part of the etching equipment itself, and a carrier for receiving the circuit board can be placed on the supporting table. When the circuit boards on the carrier are full, they can be transported by a trolley.

[0012] Preferably, it also includes a cylinder, a push plate is provided on the driving shaft of the cylinder, the cylinder is arranged below the roller, the unloading member includes two unloading rods arranged in parallel, the two unloading rods are fixed on the rotating shaft, the bottom ends of the unloading rods are hook-shaped, and the driving device can drive the two unloading rods to flip onto the conveying part.

[0013] When the driving device drives the two unloading rods to flip to the ends of the carrying platform, the push plate can push the circuit boards on the two unloading rods to the carrying platform.

[0014] Therefore, when the rotating roller conveys the etched circuit board to the two unloading rods, since the bottom end of the unloading rod is hook-shaped, the bottom end of the unloading rod will hold the circuit board upward to ensure that the circuit board will not slip off the unloading rod during the flipping process. When the two unloading rods holding the circuit boards are flipped to the ends of the supporting platform, as long as the hook-shaped openings at the bottom of the unloading rods are tilted toward the top of the supporting platform, the push plate can push the circuit boards on the two unloading rods onto the supporting platform under the action of the cylinder. A carrier rack for holding the circuit boards can be placed on the supporting platform. Under the action of the push plate, the circuit boards can be stacked horizontally on the carrier rack. After the circuit boards on the carrier rack are full, they can be transported by a trolley.

[0015] Preferably, the four rollers close to the supporting platform are all discontinuous, and each of the discontinuous rollers includes three sub-rollers. A gap for accommodating a discharge rod is left between two adjacent sub-rollers on the same roller, and the driving device can drive the two discharge rods to flip into the gap between two adjacent sub-rollers on the same roller.

[0016] Therefore, under the action of the driving device, the rotating shaft drives the two blanking rods to turn over. The two blanking rods can respectively turn over into the gaps between adjacent sub-drums on the four discontinuous drums. In this way, under the combined action of the continuous drum and the four discontinuous drums, the circuit board can be automatically conveyed onto the two connecting rods. When the edge of the circuit board is accommodated in the hook-shaped part at the bottom end of the blanking rod, the driving device drives the two blanking rods to turn over in the reverse direction through the rotating shaft. The blanking rods turning over into the gaps between adjacent sub-drums on the four discontinuous drums can ensure that the circuit board is automatically conveyed onto the blanking rods without affecting the normal rotation of the discontinuous drums.

[0017] Preferably, the top end of the blanking rod is provided with an inclined surface.

[0018] Therefore, when the two blanking rods respectively turn over into the gaps between adjacent sub-drums on the four discontinuous drums, the inclined surface at the top of the blanking rod can ensure that the circuit board on the drum can be smoothly conveyed onto the blanking rod, preventing the circuit board from getting stuck at the end of the blanking rod.

[0019] Preferably, a first roller is provided at the free end of the bottom end of the blanking rod.

[0020] Therefore, when the push plate pushes the circuit boards on the two blanking rods onto the loading platform, the presence of the first roller can ensure that the circuit boards on the blanking rods are smoothly pushed onto the loading platform, and can also prevent the free end of the bottom end of the blanking rod from scratching the circuit board.

[0021] Preferably, a second roller is provided at the bottom end of the blanking rod.

[0022] Therefore, after the circuit boards on the two blanking rods are pushed onto the loading platform, during the process of the blanking rod turning back to its original position, the presence of the second roller can prevent the bottom end of the blanking rod from scratching the circuit board on the loading platform.

[0023] Preferably, it further includes an L-shaped connecting rod. The driving device is a cylinder. One end of the L-shaped connecting rod is fixedly arranged on the rotating shaft, the other end of the L-shaped connecting rod is hinged on the driving shaft of the driving device, and the cylinder body of the driving device is hinged on the loading platform.

[0024] Therefore, in this way, when the driving shaft of the driving device (cylinder) makes an extending action, the rotating shaft can be driven to rotate forward through the L-shaped connecting rod. The rotating shaft rotating forward can drive the blanking part to transfer the circuit board on the drum to the loading platform. When the driving shaft of the driving device (cylinder) makes a retracting action, the rotating shaft can be driven to rotate in the reverse direction through the L-shaped connecting rod. The rotating shaft rotating in the reverse direction can drive the blanking part to turn over onto the conveying part. Due to the cylinder body of the driving device being hinged on the loading platform and the action of the L-shaped connecting rod, the linear motion of the driving shaft of the driving device (cylinder) can be converted into the circular motion of the rotating shaft.

[0025] Preferably, it further includes a conveyor belt. There are two parallel bosses arranged on the bearing platform, and the conveyor belt is arranged between the two bosses.

[0026] The driving device drives the rotating shaft to rotate so that the blanking part transfers the circuit board on the roller to the boss.

[0027] Therefore, a carrier for receiving the circuit board can be placed on the conveyor belt. When the circuit boards on the carrier are full, under the action of the conveyor belt, the carrier can be conveyed to the trolley together with the circuit boards. Because the carrier will be very heavy when it is full of circuit boards, the carrier can be easily transferred to the trolley together with the circuit boards through the conveyor belt.

[0028] Preferably, it further includes a carrier for transferring the circuit board. The carrier is placed on the conveyor belt and between the two bosses, and the height of the conveyor belt is less than the height of the bosses.

[0029] Therefore, the blanking part can transfer the circuit board on the roller to the carrier. When the circuit boards on the carrier are full, under the action of the conveyor belt, the carrier can be conveyed to the trolley together with the circuit boards. Because the carrier will be very heavy when it is full of circuit boards, the carrier can be easily transferred to the trolley together with the circuit boards through the conveyor belt. In addition, since the height of the conveyor belt is less than the height of the bosses, both sides of the carrier will be limited by the bosses, preventing the carrier from moving left and right during the process of transferring the circuit board to the carrier and affecting the blanking.

[0030] Preferably, it further includes a frame, and both the conveying part and the bearing platform are arranged on the frame.

[0031] Therefore, the frame can provide support for the conveying part and the bearing platform, making the blanking device form a whole and facilitating the overall movement. Description of the Drawings

[0037] Embodiment 1:

[0038] Figure 1 and Figure 2 The structure of a material unloading device in a printed circuit board etching process according to an embodiment of the utility model is schematically shown.

[0039] See also Figure 1 and Figure 2 The unloading device of the printed circuit board etching process includes a conveying part, a carrying platform 2, a unloading part 3, a rotating shaft 4, a driving device 5, a cylinder 6, an L-shaped connecting rod 7, a conveyor belt 8 and a frame 10.

[0040] See also Figure 1 The conveying part includes a plurality of rollers 11 arranged in parallel, and the conveying part is installed at the outlet end of the etching equipment. The rollers 11 can convey the etched circuit board conveyed from the outlet end of the etching equipment. The conveying part can be the conveying part of the etching equipment. In this embodiment, the four rollers 11 close to the supporting platform 2 are all discontinuous, and each discontinuous roller 11 includes three synchronously rotating sub-rollers 111. A gap is left between two adjacent sub-rollers 111 on the same roller 11, that is, each discontinuous roller 11 has two such gaps, and the gap is used to accommodate the blanking piece 3.

[0041] See also Figure 1 The carrying platform 2 is located at the side of the conveying part and the height of the carrying platform 2 is lower than the height of the roller 11. The carrying platform 2 is located in the downstream direction of the conveying part.

[0042] See also Figure 1 The conveying part and the carrying platform 2 are both installed on the frame 10. The frame 10 can provide support for the conveying part and the carrying platform 2, so that the unloading device forms a whole, which is convenient for overall movement.

[0043] Refer to Figure 2 , the blanking member 3 is used to transfer the circuit board on the roller 11 to the carrier 2.

[0044] Refer to Figure 2 , the blanking member 3 includes two blanking rods 31 arranged in parallel. The two blanking rods 31 are fixed on the rotating shaft 4. The two blanking rods 31 can rotate synchronously with the rotating shaft 4. The bottom end of the blanking rod 31 is hook-shaped. An inclined surface 311 is formed at the top end of the blanking rod 31. A first roller 312 is installed at the free end of the bottom end of the blanking rod 31. The first roller 312 can rotate freely on the blanking rod 31. A second roller 313 is also installed at the bottom end of the blanking rod 31. The second roller 313 can rotate freely on the blanking rod 31. The first roller 312 is located above the second roller 313. Specifically, the installation method can be: a T-shaped connecting plate 314 is installed at the side position near the bottom end of the blanking rod 31. The T-shaped connecting plate 314 is arranged in parallel with the blanking rod 31. A hook-shaped part is formed between the T-shaped connecting plate 314 and the blanking rod 31. The first roller 312 is installed on the top of the T-shaped connecting plate 314, and the second roller 313 is installed on the bottom of the T-shaped connecting plate 314; when the two blanking rods 31 are respectively flipped into the gaps between adjacent sub-rollers 111 on the four non-continuous rollers 11, the inclined surface 311 at the top of the blanking rod 31 can ensure that the circuit board on the roller 11 can be smoothly conveyed onto the blanking rod 31, preventing the circuit board from getting stuck at the end of the blanking rod 31. When the circuit boards on the two blanking rods 31 are pushed onto the carrier 2, during the process of the blanking rod 31 flipping back to its original position, the presence of the second roller 313 can prevent the bottom end of the blanking rod 31 from scratching the circuit board on the carrier 2.

[0045] Refer to Figure 1 and Figure 2, two parallel arranged mounting plates 41 are installed on the carrier table 2. One end of the rotating shaft 4 is installed on one mounting plate 41 through a bearing, and the other end of the rotating shaft 4 is installed on the other mounting plate 41 through a bearing. The rotating shaft 4 can rotate on the two mounting plates 41. One end of the L-shaped connecting rod 7 is fixed to the end of the rotating shaft 4, and the other end of the L-shaped connecting rod 7 is hinged to the drive shaft 51 of the driving device 5. The cylinder block of the driving device 5 is hinged to the carrier table 2. In this embodiment, the driving device 5 is a cylinder. In this way, when the drive shaft 51 of the driving device 5 (cylinder) makes an extending action, the rotating shaft 4 can be driven to rotate forward through the L-shaped connecting rod 7. The rotating shaft 4 rotating forward can drive the two blanking rods 31 to transfer the circuit board on the roller 11 to the carrier table 2. When the drive shaft 51 of the driving device 5 (cylinder) makes a retracting action, the rotating shaft 4 can be driven to rotate reversely through the L-shaped connecting rod 7. The rotating shaft 4 rotating reversely can drive the two blanking rods 31 to turn into the gap between two adjacent sub-rollers 111 on the four non-continuous rollers 11. Due to the fact that the cylinder block of the driving device 5 is hinged to the carrier table 2 and the action of the L-shaped connecting rod 7, the linear motion of the drive shaft 51 of the driving device 5 (cylinder) can be converted into the circular motion of the rotating shaft 4. In other embodiments, the driving device 5 can also be a motor. The motor is installed on the mounting plate 41 through a bracket, and the motor drives the rotating shaft 4 to rotate forward or reversely.

[0046] Refer to Figure 2, a pallet 63 is installed between two mounting plates 41, a fixing plate 64 is installed on the pallet 63, a cylinder 6 is fixed on the fixing plate 64, a push plate 61 is fixed on the driving shaft of the cylinder 6, and the cylinder 6 is located below the roller 11; under the action of the driving device 5, the two blanking rods 31 are flipped to the gap between two adjacent sub-rollers 111 on the four rollers 11 in a non-continuous state, and the rotating roller 11 conveys the etched circuit board to the two blanking rods 31. Since the bottom end of the blanking rod 31 is hook-shaped, the bottom end of the blanking rod 31 will hold up the circuit board upward to ensure that the circuit board will not slip off the blanking rod 31 during the flipping process of the blanking rod 31. When the two blanking rods 31 carrying the circuit board are flipped to the end of the bearing platform 2, by setting the stroke of the driving device 5 (cylinder), it can be ensured that the opening of the hook shape at the bottom of the blanking rod 31 is inclined upward towards the bearing platform 2. Then, under the action of the cylinder 6, the push plate 61 can push the circuit boards on the two blanking rods 31 onto the bearing platform 2. A bearing rack for receiving the circuit board can be placed on the bearing platform 2. Under the action of the push plate 61, the circuit boards can be stacked horizontally on the bearing rack. After the circuit boards on the bearing rack are full, they can be transported by a small cart. When the push plate 61 pushes the circuit boards on the two blanking rods 31 onto the bearing platform 2, the presence of the first roller 312 on the blanking rod 31 can ensure that the circuit boards on the blanking rod 31 are smoothly pushed onto the bearing platform 2, and can also prevent the free end (the position where the first roller 312 is installed) at the bottom end of the blanking rod 31 from scratching the circuit board.

[0047] Refer to Figure 1 and Figure 2 , two parallelly arranged bosses 21 are installed on the bearing platform 2, a conveyor belt 8 is installed between the two bosses 21, the height of the conveyor belt 8 is less than the height of the boss 21, the conveying direction of the conveyor belt 8 is the same as the length direction of the boss 21, the number of the conveyor belts 8 is two, one closed conveyor belt 8 is close to one boss 21, and the other closed conveyor belt 8 is close to the other boss 21. A bearing rack for receiving the circuit board can be placed on the two conveyor belts 8. The height of the bearing surface of the bearing rack for receiving the circuit board is slightly higher than that of the boss 21. The two blanking rods 31 can transfer the circuit boards on the roller 11 to the bearing rack. When the circuit boards on the bearing rack are full, under the action of the conveyor belt 8, the bearing rack 8 can be conveyed to the small cart together with the circuit boards. Because the bearing rack is very heavy after being full of circuit boards, the bearing rack can be easily transported to the small cart through the conveyor belt 8.

[0048] Refer to Figure 1 and Figure 2The conveying part of the unloading device of the printed circuit board etching process of the utility model is installed at the outlet end of the etching equipment. The roller 11 can convey the etched circuit board delivered from the outlet end of the etching equipment. Under the action of the driving device 5, the two unloading rods 31 are flipped to the gap between two adjacent sub-rollers 111 on the four rollers 11 in a non-continuous shape. The rotating roller 11 can convey the etched circuit board to the two unloading rods 31. The hook-shaped part at the bottom end of the unloading rod 31 will hold the circuit board upward. Under the action of the driving device 5, the two unloading rods 31 holding the circuit board are flipped to the supporting rollers 11. The end of the carrier 2, and then under the action of the cylinder 6, the push plate 61 pushes the circuit board on the two unloading rods 31 onto the carrier 2. The unloading device of the utility model can transfer the etched circuit board on the roller 11 to the carrier 2 by driving the two unloading rods 31 to flip and reverse directions through the driving device 5. Since the conveying part can be the conveying part of the etching equipment, the core structure of the unloading device of the utility model is the driving device 5, the rotating shaft 4, the two unloading rods 31, the cylinder 6 and the push plate 61. The structure is simple and the cost is low. It only needs to set the working mode of the driving device 5 in advance.

[0049] Embodiment 2:

[0050] Figure 3 The structure of a material unloading device for a printed circuit board etching process according to another embodiment of the utility model is schematically shown.

[0051] See also Figure 3 The unloading device of the printed circuit board etching process includes a conveying part, a carrying platform 2, a unloading part 3, a rotating shaft 4, a driving device 5, a cylinder 6, an L-shaped connecting rod 7, a conveyor belt 8, a carrying frame 9 and a frame 10.

[0052] See also Figure 3 Compared with Example 1, this embodiment only installs one more carrier 9, which is used to transfer circuit boards. The carrier 9 is placed on two conveyor belts 8 and located between two bosses 21. The height of the bearing surface of the carrier 9 for receiving the circuit boards is slightly higher than the boss 21, and the width of the carrier 9 is slightly smaller than the distance between the two bosses 21. The two unloading rods 31 and the push plate 61 can transfer the circuit boards on the roller 11 to the carrier 9. When the circuit boards on the carrier 9 are full, the carrier 9 can be transferred to the trolley together with the circuit boards under the action of the conveyor belt 8. Because the carrier 9 will be very heavy after being full of circuit boards, the carrier 9 can be easily transferred to the trolley together with the circuit boards through the conveyor belt 8. The height of the trolley can be designed to be equivalent to the height of the conveyor belt 8. In this way, the conveyor belt 8 can directly transfer the carrier 9 to the trolley, which is very convenient.

[0053] The above are only some embodiments of the present utility model, aiming to illustrate the technical means of the present utility model, rather than limiting the technical scope of the present utility model. Obvious improvements made by those skilled in the art in combination with the existing well-known common sense all fall within the protection scope of the present utility model.
