Technical Field
[0001] The present application relates to the technical field of PCB board processing and drying, and particularly to a baking operation device for PCB boards and a baking system to which the same is applied. Background Art
[0002] A PCB board, namely a printed circuit board, is abbreviated as a printed board. A PCB board is one of the important components in the electronics industry. In most electronic devices, such as small electronic watches and calculators, or large computers and communication electronic devices, there are electronic components such as integrated circuits, and thus PCB boards are required.
[0003] Currently, a conveying mechanism disclosed in Chinese Utility Model Patent No. CN210619426U for adaptively changing a PCB from a horizontal position to a vertical position includes a drive shaft, an outer side of the drive shaft is sleeved with a conveyor belt, and a plurality of uniformly arranged clamps are installed on a surface of the conveyor belt; each clamp includes a strip-shaped mounting plate, both sides of the mounting plate are bent upward, and a clamping groove is formed at a bent portion, one end of the clamping groove is fixedly connected with a fixed plug, and the other end is slidably installed with a movable plug, and V-shaped clamping strips are arranged on both the fixed plug and the movable plug.
[0004] When the PCB board is conveyed in a horizontal position after being coated by a coating roller, the ink coated on the PCB board will be damaged. Therefore, after the PCB board is coated, it is conveyed in a vertical transportation mode. The above-mentioned conveying mechanism for adaptively changing a PCB from a horizontal position to a vertical position is inconvenient for transporting the vertically conveyed PCB board. Summary of the Invention
[0005] In order to facilitate the transportation of PCB boards conveyed in the vertical direction. The present application provides a baking operation device for PCB boards and a baking system to which the same is applied.
[0006] The baking operation device for PCB boards provided by the present application adopts the following technical solutions:
[0007] A baking operation device for PCB boards, comprising:
[0008] A frame, one end of the frame is a feeding end, and the other end is a discharging end; a driving roller is rotatably connected to the frame;
[0009] A transportation mechanism, which is wound around the driving roller and can move along with the rotation of the driving roller, a plurality of support rods are fixedly connected to the transportation mechanism, the plurality of support rods are arranged in parallel, and an extending direction of each support rod is perpendicular to a conveying direction of the transportation mechanism;
[0010] A plurality of clamping mechanisms, fixedly connected to the support rods, each clamping mechanism includes:
[0011] The housing is fixedly connected to the support rod. One end of the housing away from the support rod is a clamping end, and a clamping groove is formed at the clamping end of the housing.
[0012] The control rod is movably connected within the housing, and one end of the control rod passes through the end of the housing close to the support rod.
[0013] The linkage rod group is located within the housing, and the linkage rod group is connected to the end of the control rod located within the housing.
[0014] The abutting rod is located at the clamping end of the housing. The abutting rod is connected to the linkage assembly. The abutting rod is inserted into the clamping groove and abuts against the clamping end of the housing.
[0015] The elastic member is located within the housing. One end of the elastic member is connected to the linkage rod group, and the other end is connected to the abutting end of the housing. The elastic member is used to make the abutting rod abut against the clamping end of the housing.
[0016] The clamping mechanism is fixedly connected to the frame. There are two clamping mechanisms. One clamping mechanism is located at the feeding end of the frame, and the other is located at the discharging end of the frame. The clamping mechanism includes a telescopic member that telescopically moves in the vertical direction. Abutting plates are fixedly connected to the bottom of the telescopic member. When the abutting plates move downward, they can control the control rod to move towards the inside of the housing. The control rod drives the linkage assembly to rotate within the housing, and the linkage assembly drives the abutting rod away from the clamping end of the housing, so that the clamping mechanism is in an open state.
[0017] By adopting the above technical solution, the driving roller rotates to drive the transportation mechanism to move, thereby driving the support rod to move. The support rod clamps the PCB board through the clamping mechanism. When the support rod moves to the feeding end of the frame, the abutting plate of the clamping mechanism moves downward and abuts against the control rod of the clamping mechanism, causing the support rod of the clamping mechanism to move away from the abutting member, so that the clamping mechanism is in an open state. When the PCB board is vertically placed between the support rod and the abutting member, the abutting plate of the clamping mechanism is controlled to move upward, so that the clamping mechanism clamps the PCB board in a vertical state, completing the feeding of the vertical PCB board. Then the transportation mechanism transports the vertically placed PCB board to the discharging end. When the support rod moves to the discharging end of the frame, the clamping mechanism at the discharging end controls the abutting plate to move downward and abut against the control rod of the clamping mechanism, so that the clamping mechanism is in an open state, thereby transferring the PCB board.
[0018] The above clamping mechanism facilitates clamping of the vertically placed PCB board, thereby facilitating transportation of the PCB board conveyed in the vertical direction. The coated PCB board does not need to be conveyed in a lying manner, reducing damage to the coated PCB board during lying transportation.
[0019] Optionally, an installation groove is formed on the outer shell, and the outer shell is installed on the support rod through the installation groove.
[0020] By adopting the above technical solution, the arrangement of the installation groove facilitates the installation and disassembly of the clamping mechanism, so as to facilitate the replacement after the clamping mechanism is damaged.
[0021] Optionally, a plurality of installation positions are provided on the support rod, and the clamping mechanism is installed on the installation positions.
[0022] By adopting the above technical solution, according to the size of the PCB board, an appropriate number of clamping mechanisms are installed at appropriate positions on the support rod, so as to adapt to PCB boards of different sizes.
[0023] Optionally, four clamping mechanisms are provided, and the four clamping mechanisms are evenly distributed along the length direction of the support rod.
[0024] By adopting the above technical solution, the four clamping mechanisms can clamp the PCB board more stably.
[0025] Optionally, the transport mechanism is a double-row chain. There are two groups of double-row chains. The support rod is located between the two groups of double-row chains. A double-row gear is fixedly connected to the driving roller, and the double-row gear meshes with the double-row chain.
[0026] By adopting the above technical solution, when there are more support rods arranged on the transport mechanism, the total weight of the transport mechanism is large and a large traction force is required. Utilizing the characteristic of the large strength of the double-row chain, the service life of the transport mechanism is extended.
[0027] Optionally, a supporting block is fixedly connected to the frame. The supporting block is located below the double-row chain. A sliding groove is formed in the supporting block along the length direction of the double-row chain. The sliding groove penetrates through the length direction of the supporting block. Both sides of the upper end of the supporting block abut against the rollers of the double-row chain.
[0028] By adopting the above technical solution, the supporting block plays a supporting role for the double-row chain. At the same time, the support of the supporting block for the rollers of the double-row chain reduces the friction between the supporting block and the double-row chain.
[0029] Optionally, a guiding roller is fixedly connected to the frame. The transport mechanism is wound around the guiding roller. The guiding roller is arranged in parallel with the driving roller and has a height difference.
[0030] By adopting the above technical solution, the space inside the conveying mechanism is opened up by the guiding roller, which is convenient for the installation of the pressing and clamping mechanism.
[0031] Optionally, the pressing and clamping mechanism includes a pressing and clamping frame, on which a guiding rod is slidably connected vertically. The guiding rods are located on both sides of the telescopic member. A linear bearing is arranged between the guiding rod and the pressing and clamping frame. The bottom end of the guiding rod is fixedly connected to the abutting plate.
[0032] By adopting the above technical solution, with the arrangement of the guiding rod, the movement of the abutting plate is made more stable, and the arrangement of the linear bearing reduces the friction force of the guiding rod in the vertical direction.
[0033] The present application also discloses a baking system applying the PCB board baking and conveying device, an oven and the above-mentioned PCB board baking and conveying device. The oven is located below the frame. Part of the conveying mechanism is arranged inside the oven and the conveying mechanism circulates inside the oven and on the top plate.
[0034] By adopting the above technical solution, the lower part of the conveying mechanism is arranged inside the oven to heat the PCB board, and the upper part of the conveying mechanism with empty clamps is arranged outside the oven. Thereby, the volume set inside the oven is reduced, and the energy consumption is reduced. And the blocking of the hot air blown from top to bottom in the oven by the conveying mechanism is reduced, making the baking of the PCB board more uniform.
[0035] Optionally, fiber optic sensors are arranged at both the feeding end and the discharging end of the frame. The fiber optic sensors are located on the path of the support rod. When the support rod moves to the position of the fiber optic sensor, the fiber optic sensor stops the driving roller from rotating and at the same time makes the telescopic member move downward.
[0036] By adopting the above technical solution, the movement of the support rod is sensed by the fiber optic sensor to complete the feeding or discharging action of the PCB board, reducing the error of manual operation.
[0037] In summary, the present application includes at least one of the following beneficial technical effects:
[0038] 1. Through the cooperation of the frame, the conveying mechanism, the clamping mechanism and the pressing and clamping mechanism, the vertical PCB board is clamped by the clamping mechanism, thereby achieving the effect of facilitating the transportation of the PCB board conveyed in the vertical direction.
[0039] 2. Through the cooperation between the double-row chain and the double-row gear teeth, the effect of increasing the load of the conveying mechanism is achieved.
[0040] 3. Through the arrangement of the guiding roller, the upper part of the conveying mechanism is located outside the oven, thereby reducing the internal space required by the oven and reducing the blocking of the hot air by the upper part, thus achieving the effect of improving the utilization efficiency of the heat inside the oven.

[0053] The following further elaborates on this application in conjunction with the attached Figure 1-10 drawings.
[0054] An embodiment of the present application discloses a PCB board baking and conveying device.
[0055] Referring to Figure 1 , the PCB board baking and conveying device includes a frame 1, a driving roller 2 is rotatably connected to the frame 1, a conveying mechanism 3 is wound around the driving roller 2, a support rod 4 is fixedly connected to the conveying mechanism 3, and a clamping mechanism 5 is installed on the support rod 4. A pressing and clamping mechanism 6 is fixedly connected to the frame 1, and the pressing and clamping mechanism 6 is used to control the clamping mechanism 5 to clamp the vertical PCB board. The clamping mechanism 5 is used to clamp the vertically conveyed PCB board and is conveyed through the conveying mechanism 3, so as to facilitate the conveyance of the PCB board conveyed in the vertical direction.
[0056] Referring to Figure 2 and Figure 3 , two guiding rollers 8 are fixedly connected to the frame 1, the guiding rollers 8 are arranged parallel to the driving roller 2, and the two guiding rollers 8 are located above the driving roller 2. By arranging the guiding rollers 8, a larger space is propped up inside the conveying mechanism 3, thus facilitating the installation of the pressing and clamping mechanism 6.
[0057] Refer to Figure 3 , two double-row gears 21 are fixedly connected to the driving roller 2, two double-row gears 21 are rotatably connected to the guiding rollers 8, the conveying mechanism 3 is two double-row chains 31, and the double-row chains 31 are respectively meshed with the double-row gears 21 on the driving roller 2 in a one-to-one correspondence, and the double-row gears 21 on the guiding rollers 8 are also meshed with the double-row chains 31 in a one-to-one correspondence.
[0058] Referring to Figure 2 and Figure 3 , one end of the frame 1 is a feeding end 11, the other end is a discharging end 12, driving motors 13 are respectively fixedly connected to the discharging end 12 and the feeding end 11 of the frame 1, the driving motors 13 are connected to the driving roller 2, and the driving motors 13 drive the driving roller 2 to rotate.
[0059] Referring to Figure 3 and Figure 4 , a supporting block 14 is fixedly connected to the frame 1, and the supporting block 14 is located below the double-row chain 31. The supporting block 14 is used to support the double-row chain 31, so as to prevent the double-row chain 31 from breaking due to excessive load. A chute 15 is provided in the middle of the supporting block 14 along the length direction of the double-row chain 31. The arrangement of the chute 15 enables the rollers of the double-row chain 31 to lap on the chute 15, thereby reducing the friction between the chute 15 and the double-row chain 31.
[0060] Referring to Figure 3 and Figure 4, the support rod 4 is fixedly connected between two double-row chains 31. The length direction of the support rod 4 is parallel to the axis direction of the driving roller 2. There are several support rods 4, and several support rods 4 are evenly distributed on the double-row chains 31. Refer to Figure 5 , the support rod 4 is arranged with a rectangular inner cavity. The rectangular setting of the support rod 4 facilitates the installation of the clamping mechanism 5, and the hollow setting of the support rod 4 can reduce the weight of the support rod 4. There are several mounting positions 41 on the support rod 4. In this embodiment, there are mounting positions 41. The support rod 4 and the clamping mechanism 5 are fixed by screws. By setting a plurality of mounting positions 41, different numbers of clamping mechanisms 5 can be installed on different mounting positions 41 according to the size of the PCB board to adapt to PCB boards of different sizes.
[0061] Refer to Figure 5 , Figure 6 and Figure 7 , the clamping mechanism 5 includes a housing 51. The middle of the housing 51 is hollow. One end of the housing 51 is provided with a rectangular mounting groove 511. By clamping the rectangular mounting groove 511 on the housing 51 to the support rod 4, and then positioning the housing 51 on the mounting position 41 by screws, the installation of the clamping mechanism 5 is completed.
[0062] Refer to Figure 6 and Figure 7 , one end of the housing 51 pointing to the outside of the transport mechanism 3 is the clamping end 512. A clamping groove 513 is provided on the clamping end 512. One end of the control rod 52 is located inside the housing 51, and the other end passes through the housing 51 and bends at 90° towards the support rod 4. The bent control rod 52 increases the contact area, so that the control rod 52 is convenient for abutting. And after the control rod 52 is pressed a certain distance, it will contact the support rod 4, thus avoiding the possibility of deformation of the control rod 52 caused by excessive pressing.
[0063] Refer to Figure 7, one end of the control rod 52 located inside the housing 51 is connected with a linkage rod group 53. The linkage rod group 53 includes a movable rod 531, a connecting rod 532 and a transmission rod 533. The movable rod 531 is a straight rod, and the connecting rod 532 is a curved rod. One end of the movable rod 531 away from the control rod 52 is rotatably connected to the housing 51, and the bent part of the connecting rod 532 is rotatably connected to the housing 51. The transmission rod 533 is rotatably connected to one end of the connecting rod 532 away from the control rod 52, and the transmission rod 533 is a straight rod. One end of the transmission rod 533 away from the connecting rod 532 is rotatably connected with an abutting rod 54. The abutting rod 54 is a bent rod. One end of the abutting rod 54 is rotatably connected inside the housing 51, and the other end passes through the housing 51 and is located in the clamping groove 513. One end located in the clamping groove 513 abuts against the clamping end 512 of the housing 51. The end of the abutting rod 54 located in the clamping groove 513 is provided with anti-slip teeth 541, and the anti-slip teeth 541 make the abutting rod 54 more stable when abutting against the PCB board.
[0064] Refer to Figure 7 , an elastic member 55 is further arranged inside the housing 51. The elastic member 55 in this embodiment is a spring. One end of the elastic member 55 is connected to the housing 51, and the other end is connected to the connecting rod 532. One end of the elastic member 55 connected to the housing 51 is close to the abutting member, and one end of the elastic member 55 connected to the housing 51 is close to the abutting rod 54. Through the pulling force of the elastic member 55 on the connecting rod 532 and the transmission of the transmission rod 533, the abutting rod 54 is made to abut against the abutting member.
[0065] Through the cooperation of the control rod 52, the movable rod 531, the connecting rod 532, the transmission rod 533 and the abutting rod 54 in the clamping mechanism 5, the pulling force of the spring on the connecting rod 532 is converted into the abutting force of the abutting rod 54 on the abutting member, so that the PCB board is clamped between the abutting rod 54 and the abutting member.
[0066] The limit of the movable rod 531 on the control rod 52 enables the control rod 52 to move within a specified range inside the housing 51. When the control rod 52 is moved into the control frame, through the linkage of the connecting rod 532 and the transmission rod 533, the abutting rod 54 is made to rotate away from the abutting member, so as to place the PCB board between the abutting rod 54 and the abutting member or take out the PCB board from between the abutting rod 54 and the abutting member.
[0067] Refer to Figure 7 , a limit pin 56 is further arranged inside the housing 51. The limit pin 56 is on the rotation paths of the movable rod 531 and the connecting rod 532. During the installation process of the clamping mechanism 5, when the elastic member 55 is not installed, the setting of the limit pin 56 on the path of the connecting rod 532 can reduce the possibility of the abutting rod 54 flipping outside the housing 51 and causing the clamping mechanism 5 to be assembled incorrectly.
[0068] Refer to Figure 1And Figure 8 There are two clamping mechanisms 6. One is fixedly connected to the feeding end 11 of the frame 1, and the other is fixedly connected to the discharging end 12 of the frame 1. The clamping mechanism 6 includes a clamping frame 61, a telescopic member 62, and an abutting plate 63. The clamping frame 61 is fixedly connected to the frame 1, and the telescopic member 62 is fixedly connected to the clamping frame 61. The telescopic member 62 can be a lead screw assembly or a cylinder 621. In this embodiment, a three-axis cylinder 621 is adopted. The piston rod of the cylinder 621 is vertically oriented, and the abutting plate 63 is fixedly connected to the lowest end of the piston rod.
[0069] The abutting plate 63 is driven by the cylinder 621 to move vertically downward, so as to abut against the control rod 52 of the clamping mechanism 5, making the abutting rod 54 of the clamping mechanism 5 away from the abutting member, thus facilitating the loading or unloading of the PCB board.
[0070] Refer to Figure 7 and Figure 8 Both ends of the clamping frame 61 are vertically provided with guide rods 64, and a linear bearing 65 is connected between the guide rods 64 and the clamping frame 61. The bottom end of the guide rod 64 is fixedly connected to the abutting plate 63. Through the action of the guide rod 64, the abutting of the abutting plate 63 against the control rod 52 is more stable.
[0071] The implementation principle of a PCB board baking and conveying device according to an embodiment of the present application is as follows: The number and size of the clamping mechanisms 5 on the support rods 4 are adjusted correspondingly according to the size of the PCB board to be transported. Then, the driving motor 13 is operated. The driving motor 13 drives the driving roller 2 to rotate, and the rotation of the driving roller 2 drives the double-row chain 31 to move. When the support rod 4 on the double-row chain 31 moves to the feeding end 11, the driving motor 13 is stopped and the clamping mechanism 6 located at the feeding end 11 is pressed down, so that the abutting rod 54 on the clamping mechanism 5 located at the feeding end 11 is away from the abutting member. Then, the PCB board is inserted between the abutting rod 54 and the abutting member. After driving the clamping mechanism 6 to reset, the driving motor continues to work. When the next support rod 4 moves to the feeding end 11, the above loading operation is repeated. When the PCB board is clamped and conveyed to the discharging end 12 by the clamping mechanism 5, the driving motor 13 is stopped, and the clamping mechanism 6 located at the discharging end 12 is pressed down, so that the abutting rod 54 on the clamping mechanism 5 located at the discharging end 12 is away from the abutting member, thereby transferring the PCB board located at the discharging end 12 to the next process. When the next PCB board is clamped and conveyed to the discharging end 12 by the clamping mechanism 5, the above unloading operation is repeated.
[0072] The present application also discloses a baking system applying the PCB board baking and conveying device.
[0073] Refer to Figure 9, an oven 7 is arranged between the feeding end 11 and the discharging end 12 of the frame 1. The driving rollers 2 are located on both sides of the oven 7, and the guiding rollers 8 are located above the oven 7. The area of the oven 7 close to the feeding end 11 is the baking area 71, and the area of the oven 7 close to the discharging end 12 is the cooling area 72.
[0074] Through the arrangement of the guiding rollers 8, the upper part of the double-row chain 31 is located outside the oven 7, so that only the lower half of the double-row chain 31 needs to be accommodated in the oven 7. Therefore, the internal space of the oven 7 can be set smaller, reducing heat loss. At the same time, through the connection between the double-row chain 31 and the support rods 4, there is a certain gap between adjacent support rods 4 to facilitate the circulation of hot air in the oven 7. At the same time, the upper half of the operating system is reduced to block the hot air inside the oven 7, making the circulation of the hot air inside the oven 7 smoother.
[0075] Refer to Figure 10 , two groups of fiber optic sensors 9 are fixedly connected to the frame 1. The fiber optic sensors 9 in this embodiment are opposed fiber optics. One group of fiber optic sensors 9 is located on the path of the support rod 4 at the feeding end 11 of the frame 1, and the other group of fiber optic sensors 9 is located on the path of the support rod 4 at the discharging end 12 of the frame 1.
[0076] When the support rod 4 moves between the two fiber optic sensors 9 of the same group, the fiber optic sensor 9 senses the support rod 4, and the fiber optic sensors 9 respectively give signals to the drive motor 13 and the cylinder 621, so that the drive motor 13 stops rotating, and at the same time the cylinder 621 presses down, so that the abutting rod 54 of the clamping mechanism 5 moves away from the abutting member.
[0077] At the feeding end 11, the PCB board is inserted between the abutting rod 54 and the abutting member, and then the cylinder 621 is driven to reset, so that the PCB board is clamped between the abutting rod 54 and the abutting member, and the drive motor 13 works. Until the next support rod 4 moves between the fiber optic sensors 9, and so on.
[0078] At the discharging end 12, the PCB board is removed from between the abutting rod 54 and the abutting member. The pressing down and resetting time of the cylinder 621 at the feeding end 11 and the discharging end 12 is the same, so that the operating system can operate cyclically.
[0079] The implementation principle of a baking system applying the PCB board baking operation device in the embodiment of the present application is: when the support rod 4 moves between the fiber optic sensors 9 at the feeding end 11, the fiber optic sensor 9 controls the drive motor 13 to stop working and makes the clamping mechanism 6 press down to complete the feeding operation; when the support rod 4 moves between the fiber optic sensors 9 at the discharging end 12, the fiber optic sensor 9 controls the drive motor 13 to stop working and makes the clamping mechanism 6 press down to complete the discharging operation.
[0080] This application reduces the obstruction of the upper part of the operating system to the hot air inside the oven 7, making the circulation of the hot air inside the oven 7 smoother. Moreover, this application uses the assembly of the double-row chain 31, the support rod 4, and the clamping mechanism 5 to convey the PCB board inside the oven 7, so that there is a certain gap between the various parts, enabling the hot air inside the oven 7 to penetrate between the PCB boards, reducing the problem of poor drying effect caused by uneven drying due to the obstruction of the hot air.
[0081] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
