Description

Technical Field

[0001] This utility model belongs to the technical field of baking equipment, and in particular relates to a high-efficiency baking equipment for PCB circuit board processing. Background Art

[0002] During PCB manufacturing, one step involves baking the PCB. Baking removes moisture from the PCB circuit board and electronic components. Furthermore, once the PCB circuit board reaches a certain temperature, the flux can better bond with the components and pads, greatly improving the soldering effect.

[0003] Chinese utility model patent CN217985577U discloses a baking device for PCB circuit board processing, comprising a support plate, a housing mounted on the upper surface of the support plate, exhaust holes penetrating the surface of the housing, and a door mounted on the front surface of the housing; an air guide tube is connected to the inner bottom surface of the support plate, and the bottom end of the air guide tube is connected to a hot air blower. The advantages are: the placement plate in the device can be installed and removed, facilitating the installation and fixation of the circuit boards and making operation more convenient; since hot air can be directly guided to the top of the placement plate, the temperature difference between placement plates at different heights can be minimized; the drive assembly can drive the annular plate to revolve, and the meshing of gears and gear rings can achieve the rotation of the gears, thus realizing the revolution and rotation of the placement plate, making the circuit board on the surface of the placement plate more evenly heated and improving the baking effect on the circuit board.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] First, the above-mentioned device can only bake a single plane of the circuit board, which cannot meet the requirements of flipping the material. Therefore, it cannot bake multiple planes of the material, and manual operation is still required to flip the material, which greatly increases the amount of manual labor.

[0006] Second, in addition, when the machine door is opened, the above-mentioned device allows manual loading and unloading of materials. However, the equipment is in a stopped state at this time and cannot be baked. The baking operation can only be carried out after the circuit board is loaded manually. This method prevents baking operations from being carried out after the machine door is opened, and increases the time for equipment to stop and for manual loading and unloading, thus reducing the baking efficiency of the materials. Utility Model Content

[0007] This utility model provides a high-efficiency baking device for PCB circuit board processing, aiming to solve the problems mentioned in the background art, which are that the above-mentioned devices cannot perform the flipping operation of the circuit board and still require manual flipping, which increases the amount of manual labor. In addition, when the above-mentioned devices are loading and unloading, the equipment is in a stopped waiting state and cannot perform baking operations, which increases the working time of the equipment and reduces the baking efficiency.

[0008] This utility model is implemented as follows: a high-efficiency baking device for PCB circuit board processing includes: a base on which a fixed plate is slidably mounted vertically; a baking oven is fixedly installed on the top wall of one end of the base; an opening is provided on the side wall of the baking oven near the fixed plate; a heating wire is fixedly installed on the inner wall of the baking oven and electrically connected to an external power supply; a lateral shifting mechanism is disposed on the base and movably connected to the fixed plate; the lateral shifting mechanism is used to drive the fixed plate closer to / away from the baking oven and to drive the fixed plate to rotate horizontally; sealing plates are fixedly installed on both side walls of the fixed plate, and the sealing plates are sealed and fitted into the opening; each sealing plate is rotatably connected to the side wall away from the fixed plate. There are at least two sets of rotating clamping mechanisms, each of which can be detachably fitted with a circuit board body to be baked. In this scheme, the device is equipped with a fixed plate, the bottom of which is equipped with a second motor. The rotation of the output end of the second motor can control the fixed plate to rotate 180° horizontally, thereby feeding the sealing plate on one side of the fixed plate and the rotating clamping mechanism on the sealing plate into the baking oven. At the same time, the operator can collect the baked circuit board on the rotating clamping mechanism on the other side of the sealing plate and assemble a new circuit board to be baked. In this way, while the operator is loading and unloading, another set of rotating clamping mechanisms is baking the circuit board in the baking oven, avoiding the process and time of equipment downtime waiting for manual loading and unloading, thereby effectively improving the processing efficiency of the equipment.

[0009] In addition, when the rotating rod rotates in this device, it drives the rotating shaft to rotate through the meshing of the active bevel gear and the driven bevel gear. The rotating shaft then drives the clamping component at its end to rotate at multiple angles in the baking oven, so that each surface of the circuit board is evenly heated by the heating wire, thereby improving the drying efficiency of the circuit board surface and reducing the amount of manual work involved in subsequent flipping.

[0010] Preferably, the lateral steering mechanism includes: a sliding groove formed on the base, one end of the sliding groove extending into the oven, a sliding seat slidably connected in the sliding groove, a fixed plate vertically disposed on the sliding seat, a drive screw rotatably connected in the sliding groove, a first motor fixedly connected to the side wall of the base, the output end of the first motor being fixedly connected to the end of the drive screw, and the sliding seat being threadedly connected to the drive screw; in this scheme, when the output end of the first motor rotates, it controls the drive screw to rotate, and the drive screw drives the sliding seat screwed to it to move horizontally in the sliding groove. The lateral movement of the sliding seat can drive the fixed plate to move closer to or away from the oven, thereby realizing the feeding or pulling of the circuit board into or out of the oven.

[0011] Preferably, the lateral steering mechanism further includes: a cavity formed in the sliding seat, and a second motor is fixedly installed on the inner top wall of the cavity, with its output end extending through to the outside of the sliding seat. The output end of the second motor is fixedly installed on the bottom wall of the fixed plate. In this scheme, when the output end of the second motor rotates, it controls the fixed plate fixed to its output end to rotate 180°, thereby sequentially sending the sealing plates at both ends of the fixed plate and the rotating clamping mechanism on the sealing plate into the baking oven.

[0012] Preferably, the sealing plate has a movable cavity, and each set of rotating clamping mechanisms includes: a vertical rotating rod rotatably connected to the movable cavity, and multiple rotating shafts rotatably connected to the side wall of the sealing plate away from the fixed plate. The multiple rotating shafts are evenly distributed along the height of the side wall of the sealing plate. Each rotating shaft is provided with a clamping component at its end away from the sealing plate, and the other end of the rotating shaft extends into the movable cavity and is fixedly connected to a driven bevel gear at its end. A driving bevel gear is fixedly installed on the outer wall of the rotating rod corresponding to the multiple driven bevel gears, and each driving bevel gear is meshed with the corresponding driven bevel gear. In this scheme, when the rotating rod rotates, it controls the rotation of the driven bevel gear meshing with it through the driving bevel gear. Since the driven bevel gear is fixedly installed on the rotating shaft, the rotation of the rotating shaft will control the clamping component fixedly connected to its end to rotate, so as to automatically adjust the flipping angle of the circuit board and realize the automatic flipping of the circuit board.

[0013] Preferably, a third motor is also fixedly installed on the top wall of the sealing plate. The output end of the third motor is fixedly connected to the top of one of the rotating rods, and a transmission wheel is fixedly installed on the outer wall of each rotating rod. A transmission belt is connected between the two transmission wheels. In this scheme, when the output end of the third motor rotates, it drives the rotating rod fixedly connected to its output end to rotate. The rotating rod also drives the rotating rod on the other side to rotate through the transmission wheel and the transmission belt, so that the rotating rods on both sides rotate synchronously, thereby completing the synchronous rotation control of multiple clamping components.

[0014] Preferably, the clamping assembly includes: a bonding plate fixedly mounted on the end of the rotating shaft, a fixed clamping plate fixedly connected to the side wall of the bonding plate away from the rotating shaft, and a movable clamping plate parallel to one side of the fixed clamping plate, the movable clamping plate and the bonding plate slidingly engaging; in this scheme, when assembling the circuit board, one side of the circuit board is pressed against the side wall of the bonding plate and positioned between the fixed clamping plate and the movable clamping plate, then one side wall of the circuit board is bonded to the fixed clamping plate (the side wall near the movable clamping plate), and then the position of the movable clamping plate is adjusted on the bonding plate so that the movable clamping plate moves closer to the circuit board and bonded to the side wall of the circuit board, and the assembly and fixation of the circuit board is completed by the cooperation of the movable clamping plate and the fixed clamping plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a high-efficiency baking device for PCB circuit board processing.

[0016] 1. This device features a fixed plate with a second motor at its bottom. The rotation of the second motor's output controls the fixed plate to rotate 180° horizontally, allowing one side of the fixed plate and its rotating clamping mechanism to be fed into the baking oven. Simultaneously, a worker can collect the baked circuit boards from the rotating clamping mechanism on the other side of the fixed plate and assemble new circuit boards to be baked. This method, with another rotating clamping mechanism baking the circuit boards inside the oven while the worker is loading and unloading, avoids the process and time of equipment downtime waiting for manual loading and unloading, thus effectively improving the processing efficiency of the equipment.

[0017] 2. In this device, when the rotating rod rotates, it drives the rotating shaft to rotate through the meshing of the active bevel gear and the driven bevel gear. The rotating shaft then drives the clamping component at its end to rotate at multiple angles in the baking oven, so that each surface of the circuit board is evenly heated by the heating wire, thereby improving the drying efficiency of the circuit board surface and reducing the amount of manual work involved in subsequent flipping.

[0032] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency baking device for PCB circuit board processing, comprising: a base 1, on which a fixed plate 11 is vertically and slidably mounted; a baking oven 12 is fixedly mounted on the top wall of one end of the base 1; an opening is provided on the side wall of the baking oven 12 near the fixed plate 11; and an electric heating wire 121 is fixedly mounted on the inner wall of the baking oven 12, the electric heating wire 121 being electrically connected to an external power supply device; a horizontal shifting mechanism 2, which is disposed on the base 1 and movably connected to the fixed plate 11; the horizontal shifting mechanism 2 is used to drive the fixed plate 11 to move closer to / away from the baking oven 12 and to drive the fixed plate 11 to rotate horizontally; sealing plates 3 are fixedly mounted on both side walls of the fixed plate 11; the sealing plates 3 are sealed and fitted into the opening; and at least two sets of rotating clamping mechanisms 4 are rotatably connected to the side wall of each sealing plate 3 away from the fixed plate 11; and the circuit board body to be baked is detachably assembled in each set of rotating clamping mechanisms 4.

[0033] Specifically, the oven 12 has a sealing strip on the outer wall of the open side. When the sealing plate 3 moves to the open side, its side wall will fit against the side wall of the oven 12, and at the same time, the sealing strip will be squeezed to fill the gap between the sealing plate 3 and the oven 12, thereby preventing heat loss.

[0034] Furthermore, the lateral steering mechanism 2 includes: a sliding groove 21 formed on the base 1, one end of the sliding groove 21 extending into the baking oven 12, a sliding seat 22 slidably connected in the sliding groove 21, a fixed plate 11 erected on the sliding seat 22, a drive screw 23 rotatably connected in the sliding groove 21, a first motor 24 fixedly connected to the side wall of the base 1, the output end of which is fixedly connected to the end of the drive screw 23, and the sliding seat 22 is also threadedly connected to the drive screw 23.

[0035] Furthermore, the lateral steering mechanism 2 also includes a cavity 25 opened in the sliding seat 22, and a second motor 26 is fixedly installed on the inner top wall of the cavity 25, with its output end extending through to the outside of the sliding seat 22. The output end of the second motor 26 is fixedly installed on the bottom wall of the fixed plate 11.

[0036] Furthermore, the sealing plate 3 has a movable cavity 31, and each set of rotating clamping mechanisms 4 includes: a vertical rotating rod 41 rotatably connected to the movable cavity 31, and multiple rotating shafts 42 rotatably connected to the side wall of the sealing plate 3 away from the fixed plate 11. The multiple rotating shafts 42 are evenly distributed along the height of the side wall of the sealing plate 3. Each rotating shaft 42 is provided with a clamping component 43 at its end away from the sealing plate 3, and the other end of the rotating shaft 42 extends into the movable cavity 31 and is fixedly connected to a driven bevel gear 44 at its end. A driving bevel gear 45 is fixedly installed on the outer wall of the rotating rod 41 corresponding to the multiple driven bevel gears 44, and each driving bevel gear 45 is meshed with the corresponding driven bevel gear 44.

[0037] Furthermore, a third motor 32 is fixedly installed on the top wall of the sealing plate 3. The output end of the third motor 32 is fixedly connected to the top of one of the rotating rods 41, and a transmission wheel 411 is fixedly installed on the outer wall of each rotating rod 41. A transmission belt 412 is connected between the two transmission wheels 411.

[0038] Specifically, in other solutions, the transmission wheel 411 can be replaced by a sprocket, and the transmission belt 412 can be replaced by a chain. The transmission of the sprocket and the chain can also drive the two rotating rods 41 to rotate synchronously in the same direction. In actual operation, the operator can freely choose according to the actual situation.

[0039] Furthermore, the clamping assembly 43 includes: a bonding plate 431 fixedly installed on the end of the rotating shaft 42, a fixed clamping plate 432 fixedly connected to the side wall of the bonding plate 431 away from the rotating shaft 42, and a movable clamping plate 433 parallel to one side of the fixed clamping plate 432, with the movable clamping plate 433 and the bonding plate 431 slidingly engaged.

[0040] Specifically, in this device, the bonding plate 431 has a strip groove on the side wall of the movable clamping plate 433. An adjusting screw is rotatably connected in the strip groove. At the same time, one end of the adjusting screw extends to the outside of the bonding plate 431 and a handle is fixedly installed on its end. The operator can drive the adjusting screw to rotate by grasping the handle. One end of the movable clamping plate 433 is inserted into the strip groove and threadedly connected to the adjusting screw. The operator can control the movable clamping plate 433 to move closer to or away from the fixed clamping plate 432 by driving the adjusting screw to adjust the distance between the fixed clamping plate 432 and the movable clamping plate 433, so as to clamp and fix circuit boards of different thicknesses.

[0041] Working principle and usage process of this utility model:

[0042] First, the second motor 26 is used manually to control the rotation of the fixing plate 11 so that one side of the sealing plate 3 faces the baking oven 12. Then, the circuit boards to be baked are assembled in the multiple clamping components 43 on the sealing plate 3. Subsequently, the output end of the first motor 24 controls the drive screw 23 to rotate, and the sliding seat 22 controls the fixing plate 11 to move towards the baking oven 12, while sending multiple circuit boards into the baking oven 12 through the opening for drying.

[0043] At this time, the circuit board can be assembled in the clamping assembly 43 on the sealing plate 3 on the other side;

[0044] After baking is complete, the output of the first motor 24 controls the sliding seat 22 to move backward (away from the baking oven 12) via the drive screw 23. After moving to a specified distance, the output of the second motor 26 controls the fixed plate 11 to flip in opposite directions, so that the circuit board that has finished baking moves to the side of the fixed plate 11 away from the baking oven 12. Then the drive screw 23 rotates to send the circuit board to be baked into the baking oven 12. The circuit board that has finished baking can be collected manually, and new circuit boards to be baked can be loaded at the same time.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
