Description

Technical Field

[0001] This utility model relates to the field of supporting equipment for PCB board processing, and in particular to a flipping device for PCB circuit board processing. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), many key processing steps (such as drilling, milling, surface mounting, soldering, coating, etc.) need to be performed on both sides of the PCB board in sequence. To achieve efficient continuous production, automated production lines are usually equipped with PCB board flipping equipment, which is used to flip the PCB board 180° after the front side is processed so that the back side can be processed.

[0003] However, since PCB board processing equipment can only process the front side of the PCB board in a single processing cycle (the first processing), the PCB board needs to be flipped to process the back side (the second processing). Currently, automated equipment is used to flip the PCB board. This equipment feeds the PCB board that has completed the first processing into a channel consisting of two parallel conveyor belts. After the PCB board enters the channel, the turntable drives the upper and lower conveyor belts to rotate 180°. The flipped PCB board is then sent out by the conveyor belt for the second processing on the back side.

[0004] However, during the flipping process of the aforementioned existing flipping equipment, when the PCB board is rotated to a non-horizontal state, larger and heavier PCB boards are prone to slipping between the upper and lower conveyor belts. Accidental slippage can not only cause physical damage or contamination to the PCB board, but also interrupt the production process and affect processing efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a flipping device for PCB circuit board processing, which uses a tension spring to pull the upper belt to fit against the lower belt to clamp the PCB board, thus preventing it from slipping off during rotation.

[0006] The technical solution adopted by the PCB circuit board processing flipping device disclosed in this utility model is:

[0007] The device includes a base, a first clamping mechanism, and a second clamping mechanism. A rotating seat is rotatably connected to the base, and a first driving assembly is provided on the base. The rotating seat is connected to the first driving assembly, and a first adjusting mechanism is slidably connected to the rotating seat. Both the first and second clamping mechanisms include two opposing mounting plates, which are respectively fixedly connected to the rotating seat and the first adjusting mechanism. The first and second clamping mechanisms are located near the two ends of the rotating seat and are parallel to each other. Two pairs of sliders are slidably connected to the mounting plates, which are located near the two ends of the mounting plates. A tension spring is fixedly connected between two adjacent sliders. A central shaft is rotatably connected to each slider. An upper pulley and a lower pulley are fixedly connected to the central shaft of each pair of sliders. An upper belt is fitted onto the two upper pulleys, and a lower belt is fitted onto the two lower pulleys. The upper belts contact the lower belts. A second driving assembly is provided on the mounting plate and is connected to one of the central shafts.

[0008] As a preferred embodiment, the mounting plate has two pairs of sliding grooves running through it, with the two pairs of sliding grooves respectively close to both ends of the mounting plate, the four sliding grooves being parallel to each other, and the central axis passing through the sliding grooves.

[0009] As a preferred embodiment, the mounting plate has two protrusions extending from it, and a limiting plate is fixedly connected to the protrusions. A through groove is formed between the limiting plate and the mounting plate, and the two pairs of sliders are respectively placed in the two through grooves for sliding contact.

[0010] As a preferred embodiment, the second drive assembly includes a second motor, which is fixedly connected to the mounting plate. The output shaft of the second motor and one of the central shafts are both fixedly connected to a second drive pulley, and an elastic belt is fitted onto the two second drive pulleys.

[0011] As a preferred embodiment, two connecting blocks are fixedly connected to one side of the rotating base, and a first rotating shaft is fixedly connected to the two connecting blocks. A second rotating shaft is fixedly connected to the other side of the rotating base. Both the first and second rotating shafts are coaxial with the center of the rotating base, and both the first and second rotating shafts are rotatably connected to the base.

[0012] As a preferred embodiment, the first drive assembly includes a first motor, which is fixedly connected to the base. One end of the output shaft and the first rotating shaft of the first motor are both fixedly connected to a first drive pulley, and a drive transmission belt is sleeved on the two first drive pulleys.

[0013] As a preferred embodiment, a first lead screw is rotatably connected to the rotating seat, and a guide rod is fixedly connected to the rotating seat. The first adjustment mechanism includes a sliding plate, and both the first lead screw and the guide rod are slidably connected to the sliding plate. One of the mounting plates of the first clamping mechanism is fixedly connected to the sliding plate, and one of the mounting plates of the second clamping mechanism is fixedly connected to the sliding plate. The two mounting plates on the sliding plate are far apart from each other.

[0014] As a preferred embodiment, the first adjustment mechanism further includes a first handwheel, which is rotatably connected to the rotating seat. One end of the first lead screw extends out of the rotating seat, and both one end of the first lead screw and one end of the first handwheel are fixedly connected to an adjustment pulley. An adjustment transmission belt is fitted onto the two adjustment pulleys.

[0015] As a preferred embodiment, the system also includes a second adjustment mechanism, wherein the base is slidably connected to the second adjustment mechanism.

[0016] As a preferred embodiment, the second adjustment mechanism includes an adjustment seat, a second lead screw rotatably connected to the adjustment seat, a guide rail fixedly connected to the adjustment seat, the second lead screw and the guide rail being slidably connected to the base, and a second handwheel fixedly connected to one end of the second lead screw.

[0017] The beneficial effects of the PCB circuit board processing flipping device disclosed in this utility model are:

[0018] The first clamping mechanism and the second clamping mechanism are respectively aligned with the discharge port of the first processing and the feed port of the second processing; the second drive assembly drives the lower pulley to rotate through one of the central shafts, thereby moving the lower belt. Since the lower belt is in contact with the upper belt, synchronous movement is achieved.

[0019] When the PCB board is fed into the first clamping mechanism after the first processing, the upper belt and the lower belt use friction to create a pulling force on the PCB board, guiding the PCB board between the upper belt and the lower belt; and the PCB board touches the upper pulley and the lower pulley to generate radial displacement, which pushes a pair of sliders away from each other and stretches the tension spring. After the PCB board passes the upper pulley and the lower pulley, the tension spring pulls the upper pulley and the lower pulley to reset, the upper belt and the lower belt clamp the PCB board, the second drive component stops running, so that the PCB board is constrained within the first clamping mechanism;

[0020] The first drive assembly drives the rotating seat to rotate 180° in the forward direction. Since the PCB board is held by the upper and lower belts, it will not slip even if the PCB board is in a vertical position, allowing the equipment to flip larger and heavier PCB boards.

[0021] After the flipping is completed, the first clamping mechanism aligns with the feed port of the second processing, and the second clamping mechanism aligns with the discharge port of the first processing. The discharge port of the first processing pushes the PCB board to the second clamping mechanism again, and the first clamping mechanism sends the PCB board into the feed port of the second processing. The dual clamping station allows the equipment to perform loading and unloading work at the same time, improving the efficiency of flipping the PCB board. Attached Figure Description

[0029] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0030] Please refer to Figure 1 and Figure 2 .

[0031] The present invention discloses a flipping device for PCB circuit board processing, comprising a base 1, a first clamping mechanism 6, a second clamping mechanism 7, and a second adjusting mechanism 5.

[0032] A rotating seat 3 is rotatably connected to the base 1. In this embodiment, the rotating seat 3 is preferably a hollow rectangular frame structure. Two connecting blocks 31 are fixedly connected to one side of the rotating seat 3. A first rotating shaft 311 is fixedly connected to the two connecting blocks 31. A second rotating shaft is fixedly connected to the other side of the rotating seat 3. The first rotating shaft 311 and the second rotating shaft are both coaxial with the center of the rotating seat 3. The first rotating shaft 311 and the second rotating shaft are both rotatably connected to the base 1.

[0033] Furthermore, a first drive assembly 21 is provided on the base 1, and the rotating seat 3 is connected to the first drive assembly 21. The first drive assembly 21 includes a first motor 211. The first motor 211 is fixedly connected to the base 1. One end of the output shaft of the first motor 211 and the first rotating shaft 311 are both fixedly connected to a first drive pulley. A drive transmission belt 212 is sleeved on the two first drive pulleys. The first motor 211 drives the rotating seat 3 to rotate a certain angle on the base 1 through the drive transmission belt 212.

[0034] A limit block 32 is fixedly connected to the other side of the rotating base 3. The limit block 32 is close to the outer side of the second rotating shaft. A mounting base is fixedly connected to the base 1. Two limit switches 22 are fixedly connected to the mounting base. Both limit switches 22 are located on the same horizontal plane.

[0035] When the first motor 211 drives the rotating seat 3 to rotate 180° in the forward direction, the limit block 32 touches one of the limit switches 22, the motor stops running, and the rotating seat 3 stops at the current angle; when the first motor 211 drives the rotating seat 3 to rotate 180° in the reverse direction to reset, the limit block 32 touches the other limit switch 22, the motor stops running, and the rotating seat 3 resets. The rotation angle of the rotating seat 3 is precisely controlled by the two limit switches 22.

[0036] Please refer to Figures 1-3 .

[0037] A first adjustment mechanism 4 is slidably connected to the rotating seat 3. A first lead screw 41 is rotatably connected to the inner wall of the rotating seat 3. The first lead screw 41 is parallel to the axis of the first rotating shaft 311 and is located on the same axis. A smooth rod 42 is fixedly connected to the inner wall of the rotating seat 3. In this embodiment, there are preferably two smooth rods 42, located on both sides of the first lead screw 41. The first lead screw 41 and the smooth rod 42 are parallel to each other. The first adjustment mechanism 4 includes a sliding plate 43 and a first handwheel 411.

[0038] Furthermore, both the first lead screw 41 and the guide rod 42 are slidably connected to the slide plate 43. The guide rod 42 restricts the slide plate 43 to slide axially only on the first lead screw 41 and the guide rod 42, so that the slide plate 43 cannot rotate with the first lead screw 41.

[0039] Furthermore, the first handwheel 411 is rotatably connected to the inner wall of the rotating seat 3. One end of the first handwheel 411 extends out of the rotating seat 3, and one end of the first lead screw 41 extends out of the rotating seat 3. One end of the first lead screw 41 and one end of the first handwheel 411 are both fixedly connected to an adjusting pulley. An adjusting transmission belt 412 is sleeved on the two adjusting pulleys. The adjusting pulley of the first lead screw 41 is located between the two connecting blocks 31.

[0040] By rotating the first handwheel 411, the first handwheel 411 drives the first lead screw 41 to rotate forward or backward through the transmission belt 412, thereby driving the slide plate 43 to slide back and forth and adjust the stopping position.

[0041] The bottom of the base 1 is slidably connected to the second adjustment mechanism 5, which includes an adjustment seat 51. A second lead screw 52 is rotatably connected to the adjustment seat 51, and the first lead screw 41 and the second lead screw 52 are parallel to each other. A guide rail 53 is fixedly connected to the adjustment seat 51. In this embodiment, it is preferable that there are two guide rails 53, which are located on both sides of the second lead screw 52, ​​and the second lead screw 52 and the guide rail 53 are parallel to each other. The second lead screw 52 and the guide rail 53 are both slidably connected to the bottom of the base 1, and a second handwheel 521 is fixedly connected to one end of the second lead screw 52.

[0042] By rotating the second handwheel 521, the second lead screw 52 is driven to rotate forward or reverse, thereby causing the base 1 to slide back and forth and adjust the stopping position.

[0043] Please refer to Figure 1 and Figures 3-7 .

[0044] The first clamping mechanism 6 and the second clamping mechanism 7 each include two opposing mounting plates 61, which are fixedly connected to the rotating seat 3 and the first adjusting mechanism 4, respectively. One of the mounting plates 61 of the first clamping mechanism 6 is fixedly connected to the slide plate 43, and the other mounting plate 61 of the first clamping mechanism 6 is fixedly connected to the inner wall of the rotating seat 3. One of the mounting plates 61 of the second clamping mechanism 7 is fixedly connected to the slide plate 43. The two mounting plates 61 on the slide plate 43 are far apart from each other, and the other mounting plate 61 of the second clamping mechanism 7 is fixedly connected to the inner wall of the rotating seat 3. The first clamping mechanism 6 and the second clamping mechanism 7 are parallel to each other, and the first clamping mechanism 6 and the second clamping mechanism 7 are close to the two ends of the rotating seat 3, respectively.

[0045] Furthermore, two pairs of sliders 62 are slidably connected to the mounting plate 61. The two pairs of sliders 62 are respectively close to both ends of the mounting plate 61. Two protrusions extend from the mounting plate 61, and a limiting plate 611 is fixedly connected to the protrusions. A through groove is formed between the limiting plate 611 and the mounting plate 61. The two pairs of sliders 62 are respectively placed in the two through grooves and slide in contact. The limiting plate 611 limits the sliders 62 to slide within the through groove.

[0046] Furthermore, a tension spring 621 is fixedly connected between two adjacent sliders 62. In this embodiment, it is preferable to have two tension springs 621, which are respectively close to the two sides of the slider 62. The tension springs 621 pull the two sliders 62 closer to each other, and the sliders 62 slide a certain distance in the through groove.

[0047] Furthermore, a central shaft 622 is rotatably connected to the slider 62, and a bearing is embedded in the slider 62. The central shaft 622 is rotatably connected to the slider 62 through the bearing. Two pairs of sliding grooves 612 are passed through the mounting plate 61. The two pairs of sliding grooves 612 are respectively close to the two ends of the mounting plate 61. The four sliding grooves 612 are parallel to each other and parallel to the through groove. The central shaft 622 passes through the sliding grooves 612.

[0048] Furthermore, the central shafts 622 on the pair of sliders 62 are respectively fixedly connected to upper pulleys 623 and lower pulleys 625. Upper belts 624 are fitted on the two upper pulleys 623, and lower belts 626 are fitted on the two lower pulleys 625. When the tension spring 621 pulls the two sliders 62 closer to each other, the central shaft 622 slides a certain distance in the slide groove 612, so that the upper belts 624 contact the lower belts 626.

[0049] Furthermore, the rotating base 3 is provided with a first optical coupler and a second optical coupler. The first optical coupler faces between the two mounting plates 61 of the first clamping mechanism 6, and the second optical coupler faces between the two mounting plates 61 of the second clamping mechanism 7.

[0050] The mounting plate 61 is provided with a second drive assembly 63, which is connected to one of the central shafts 622. The second drive assembly 63 includes a second motor 631. The second motor 631 is fixedly connected to the mounting plate 61. The output shaft of the second motor 631 and one of the central shafts 622 are both fixedly connected with second drive pulleys. The two second drive pulleys are fitted with elastic belts 632.

[0051] Furthermore, the output shaft of the second motor 631 drives one of the central shafts 622 to rotate via the elastic belt 632, thereby driving the upper belt 624 to move. Since the upper belt 624 contacts the lower belt 626, it drives the lower belt 626 to move synchronously.

[0052] When the upper pulley 623 and the lower pulley 625 are touched by the PCB board, thus pushing the two adjacent sliders 62 to slide away from each other, one of the central shafts 622 is displaced, which lengthens the distance between the central shaft 622 and the output shaft of the second motor 631. The elastic band 632 can also drive one of the central shafts 622 to rotate while being stretched. Since most PCB boards on the market are less than 1 cm thick, the sliding distance of the slider 62 is less than or equal to 1 cm. The stretching length of the elastic band 632 is short, and it is not easy to damage the elastic band 632.

[0053] Please refer to Figures 1-7 .

[0054] When deploying and configuring this equipment:

[0055] The equipment is placed close to the external processing equipment, and the inlet of the first clamping mechanism 6 and the outlet of the second clamping mechanism 7 are aligned with the outlet of the first processing and the inlet of the second processing, respectively.

[0056] By rotating the first handwheel 411, the slide plate 43 is displaced, adjusting one of the mounting plates 61 of the first clamping mechanism 6 and the second clamping mechanism 7 to align with one side of the PCB board, so that the upper belt 624 and the lower belt 626 can clamp one side of the PCB board, but one side of the PCB board will not contact the mounting plate 61; by rotating the second handwheel 521, the base 1 is displaced, adjusting the other mounting plate 61 of the first clamping mechanism 6 and the other mounting plate 61 of the second clamping mechanism 7 to align with the other side of the PCB board, so that the upper belt 624 and the lower belt 626 can clamp the other side of the PCB board, but the other side of the PCB board will not contact the mounting plate 61, thereby enabling the device to flip PCB boards of different sizes.

[0057] When the device is running:

[0058] When the PCB board is fed into the inlet of the first clamping mechanism 6 after the first processing, the upper belt 624 and the lower belt 626 use friction to generate a pulling force on the PCB board, guiding the PCB board between the upper belt 624 and the lower belt 626, and guiding the PCB board towards the middle of the first clamping mechanism 6; during the guiding process, the PCB board touches the upper pulley 623 and the lower pulley 625, generating radial displacement, which causes the upper pulley 623 and the lower pulley 625 to push a pair of sliders 62 away from each other and stretch the tension spring 62. 1. After the PCB board passes through the upper pulley 623 and the lower pulley 625, the tension spring 621 pulls the upper pulley 623 and the lower pulley 625 to reset, and the upper belt 624 and the lower belt 626 clamp the PCB board; when the PCB board blocks the first optocoupler, the second drive assembly 63 stops running, so that the PCB board is constrained in the first clamping mechanism 6. Since the first optocoupler is close to the outlet of the first clamping mechanism 6, when flipping a long PCB board, it is prevented that part of the PCB board area is not guided into the first clamping mechanism 6.

[0059] After the PCB board is fed in after the first processing, the first drive assembly 21 drives the rotating seat 3 to rotate 180° in the forward direction. Since the PCB board is clamped by the upper belt 624 and the lower belt 626, it will not slip even if the PCB board is in a vertical state, allowing the equipment to flip PCB boards that are larger and heavier.

[0060] After the flipping is completed, the outlet of the first clamping mechanism 6 is aligned with the feed port of the second processing, and the inlet of the second clamping mechanism 7 is aligned with the outlet of the first processing. The outlet of the first processing pushes the PCB board to be flipped to the inlet of the second clamping mechanism 7 again. The principle of the PCB board to be flipped being introduced into the second clamping mechanism 7 is the same as that of the first clamping mechanism 6. The second drive assembly 63 drives the upper belt 624 and the lower belt 626 to move. The outlet of the first clamping mechanism 6 sends the flipped PCB board into the feed port of the second processing. After the flipped PCB board removes the first optocoupler, the flipping and unloading of the PCB board is confirmed to be completed. After the flipped PCB board blocks the second optocoupler, the flipped PCB board is confirmed to be sent into the second clamping mechanism 7.

[0061] The first drive assembly 21 drives the rotating seat 3 to rotate 180° in the opposite direction, so that the inlet of the first clamping mechanism 6 is aligned with the outlet of the first processing, and the outlet of the second clamping mechanism 7 is aligned with the inlet of the second processing, thus completing the unloading of the flipped PCB board. The principle of the second clamping mechanism 7 is the same as that of the first clamping mechanism 6, thereby realizing a dual clamping station that allows the equipment to perform loading and unloading work at the same time, improving the efficiency of flipping the PCB board.

[0062] This utility model provides a flipping device for PCB circuit board processing, which aligns the first clamping mechanism and the second clamping mechanism with the discharge port of the first processing and the inlet of the second processing, respectively; the second drive component drives the lower pulley to rotate through one of the central shafts, thereby moving the lower belt, and the lower belt moves synchronously due to the contact between the upper belt and the lower belt.

[0063] When the PCB board is fed into the first clamping mechanism after the first processing, the upper belt and the lower belt use friction to create a pulling force on the PCB board, guiding the PCB board between the upper belt and the lower belt; and the PCB board touches the upper pulley and the lower pulley to generate radial displacement, which pushes a pair of sliders away from each other and stretches the tension spring. After the PCB board passes the upper pulley and the lower pulley, the tension spring pulls the upper pulley and the lower pulley to reset, the upper belt and the lower belt clamp the PCB board, the second drive component stops running, so that the PCB board is constrained within the first clamping mechanism;

[0064] The first drive assembly drives the rotating seat to rotate 180° in the forward direction. Since the PCB board is held by the upper and lower belts, it will not slip even if the PCB board is in a vertical position, allowing the equipment to flip larger and heavier PCB boards.

[0065] After the flipping is completed, the first clamping mechanism aligns with the feed port of the second processing, and the second clamping mechanism aligns with the discharge port of the first processing. The discharge port of the first processing pushes the PCB board to the second clamping mechanism again, and the first clamping mechanism sends the PCB board into the feed port of the second processing. The dual clamping station allows the equipment to perform loading and unloading work at the same time, improving the efficiency of flipping the PCB board.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
