Description

Technical Field

[0001] This utility model belongs to the field of vacuum electric furnace processing technology, and in particular, it is a baking device for vacuum electric furnace processing. Background Technology

[0002] A vacuum furnace is a special heat treatment device that can heat and cool materials in a vacuum environment. In order to control the temperature of the vacuum furnace, circuit boards are assembled with the vacuum furnace during processing. However, the circuit boards need to be baked during processing to remove moisture and volatile organic compounds. However, most circuit boards are currently placed in a fixed position, and the heating source of the oven is also fixed. This causes the side of the circuit board closer to the heating source to heat up faster, while the side away from the heating source heats up slower, resulting in uneven heating on both sides of the circuit board and reducing baking efficiency.

[0003] A Chinese patent (authorization announcement number CN218846763U) discloses a rapid drying mechanism for circuit board production, which includes: "a base, a motor fixedly installed inside the base, a transmission rod connected by a spline to the output end of the motor, a rotating rod fixedly installed at one end of the transmission rod, and a drying box fixedly installed at one end of the rotating rod."

[0004] It is evident that the cited patent document suffers from uneven heating on both sides of the circuit board. Utility Model Content

[0005] The purpose of this invention is to provide a baking device for vacuum electric furnace processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a baking device for vacuum electric furnace processing, comprising a baking oven, wherein rotating shafts are rotatably provided on both inner walls of the baking oven, rotating blocks are connected to opposite ends of the two rotating shafts, and connecting blocks are connected to opposite sides of the two rotating blocks, a through groove is provided on the top surface of the connecting block, a fixing block is connected to both inner walls of the through groove, a first groove is provided on one inner wall of the through groove, threaded shafts are rotatably connected to both inner walls of the first groove via pins, clamping blocks are threadedly fitted on the periphery of the two threaded shafts, clamping grooves for clamping the vacuum electric furnace circuit board are provided on both sides of the fixing block and on opposite sides of the two clamping blocks, and a driving component for driving the rotation of the threaded shafts is installed through one side of the connecting block.

[0007] Preferably, the drive assembly includes a first bevel gear, a rotating rod, a second bevel gear, and a knob, wherein the first bevel gear is fixedly sleeved on the circumference of the threaded shaft.

[0008] Preferably, the rotating rod is disposed on the inner sidewall of the first groove, and one end of the rotating rod extends through to one side of the connecting block.

[0009] Preferably, the second bevel gear is fixedly connected to the other end of the rotating rod and meshes with the first bevel gear, and the knob is fixedly connected to one end of the rotating rod that extends through to one side of the connecting block.

[0010] Preferably, one side of the connecting block is provided with a through hole for the rotating rod to pass through, and the inner wall of the through hole is provided with a bearing.

[0011] Preferably, the outer wall of the bearing is connected and fixed to the inner wall of the through hole, and the circumference of one end of the rotating rod passes through the bearing and is connected and fixed to the inner wall of the bearing.

[0012] Preferably, the inner wall of the connecting block is provided with a second groove for the two clamping blocks to enter, and a limit rod is installed on the inner wall of the second groove. Both clamping blocks are slidably sleeved on the periphery of the limit rod.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This baking device for vacuum furnace processing places the vacuum furnace circuit board in a clamping groove on one side of a fixed block. By rotating the threaded shaft, the clamping block can be moved, allowing the other side of the vacuum furnace circuit board to enter the clamping groove on one side of the clamping block, thus fixing the vacuum furnace circuit board. This facilitates rotation and flipping around the rotating shaft. Compared to existing devices for baking vacuum furnace circuit boards, this device can flip the vacuum furnace circuit board, allowing both sides of the circuit board to be baked evenly.

[0015] The drive component allows the threaded shaft to rotate, making it easier for personnel to move the clamping blocks and fix the vacuum furnace circuit board.

[0016] The installed limit rod can limit the movement trajectory of the two clamping blocks, preventing them from rotating with the threaded shaft. Attached Figure Description

Detailed Implementation

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The baking device for vacuum electric furnace processing shown includes a baking oven 1. Rotating shafts 2 are rotatably provided on both inner walls of the baking oven 1. Rotating blocks 3 are connected to opposite ends of the two rotating shafts 2. Connecting blocks 4 are connected to opposite sides of the two rotating blocks 3. A drive motor 19 is installed on one side of the baking oven 1. The output end of the drive motor 19 passes through the baking oven 1 and is fixedly connected to one end of one of the rotating shafts 2. One end of the other rotating shaft 2 is rotatably connected to the inner wall of the baking oven 1 through a pin. By turning on the drive motor 19, one of the rotating shafts 2 can be rotated, which in turn drives the rotating blocks 3 and the connecting blocks 4 to rotate, thereby driving the other rotating blocks 3 and the rotating shaft 2 to rotate.

[0029] A through groove 5 is provided on the top surface of the connecting block 4. A fixing block 6 is connected to the inner walls of both sides of the through groove 5. A first groove 7 is provided on one inner wall of the through groove 5. Threaded shafts 8 are rotatably connected to both inner walls of the first groove 7 via pins. Clamping blocks 9 are threadedly fitted around the periphery of both threaded shafts 8. Clamping slots 10 for holding the vacuum furnace circuit board are provided on both sides of the fixing block 6 and on the opposite side of the two clamping blocks 9. One side of the vacuum furnace circuit board is placed into the clamping slot 10 on one side of the fixing block 6. Then, rotating the threaded shaft 8 will move the clamping blocks 9, allowing them to approach the vacuum furnace circuit board. The other side of the vacuum furnace circuit board can be placed into the clamping groove 10 on one side of the clamping block 9. By continuing to rotate the threaded shaft 8, the two clamping grooves 10 can be pressed against the two sides of the vacuum furnace circuit board and clamped and fixed, so that baking can be carried out. When the drive motor 19 drives the rotating block 3 to rotate 180 degrees through the rotating shaft 2, it will drive the connecting block 4 to rotate 180 degrees, so that the fixed vacuum furnace circuit board can also rotate 180 degrees, realizing flipping and baking the other side of the vacuum furnace circuit board. This avoids uneven heating on both sides of the vacuum furnace circuit board and improves the baking efficiency.

[0030] A drive assembly for driving the threaded shaft 8 to rotate is installed through one side of the connecting block 4. The drive assembly includes a first bevel gear 11, a rotating rod 12, a second bevel gear 13, and a knob 14. The first bevel gear 11 is fixedly sleeved on the periphery of the threaded shaft 8. The rotating rod 12 is located on the inner side wall of the first groove 7. One end of the rotating rod 12 extends through to one side of the connecting block 4. The second bevel gear 13 is connected and fixed to the other end of the rotating rod 12 and meshes with the first bevel gear 11. The knob 14 is connected and fixed to the end of the rotating rod 12 that extends through to one side of the connecting block 4. By rotating the knob 14, the operator can drive the rotating rod 12 to rotate, thereby driving the second bevel gear 13 to rotate. Since the second bevel gear 13 meshes with the first bevel gear 11, the rotation of the second bevel gear 13 will drive the first bevel gear 11 to rotate, so that the rotating first bevel gear 11 can drive the threaded shaft 8 to rotate, and the threaded shaft 8 can drive the clamping block 9 to move.

[0031] Since the inner cavity of the first groove 7 is provided with two threaded shafts 8, the drive assembly is also provided with two, thereby enabling the rotation of the other threaded shaft 8.

[0032] One side of the connecting block 4 has a through hole 15 through which the rotating rod 12 passes. The inner wall of the through hole 15 is provided with a bearing 16. The outer wall of the bearing 16 is connected and fixed to the inner wall of the through hole 15. The circumference of one end of the rotating rod 12 passes through the bearing 16 and is connected and fixed to the inner wall of the bearing 16. When the operator rotates the knob 14 to rotate the rotating rod 12, the inner ring of the bearing 16 will rotate, so that the bearing 16 supports the position of the rotating rod 12 without affecting the rotation of the rotating rod 12.

[0033] The inner wall of the connecting block 4 is provided with a second groove 17 for the two clamping blocks 9 to enter. A limit rod 18 is installed on the inner wall of the second groove 17. The two clamping blocks 9 are slidably sleeved on the periphery of the limit rod 18. When the two clamping blocks 9 move, they will move on the periphery of the limit rod 18, so that the limit rod 18 limits the movement of the two clamping blocks 9 and prevents them from rotating with the threaded shaft 8.

[0034] The top surface of the baking oven 1 is connected to a hot air pipe 20, and the free end of the hot air pipe 20 is connected to a hot air blower. The hot air is delivered into the hot air pipe 20 through the external hot air blower and then into the baking oven 1 through the hot air pipe 20, which can increase the temperature inside the baking oven 1 and bake the circuit board of the vacuum electric furnace.

[0035] Working principle:

[0036] This baking device for vacuum furnace processing places one side of the vacuum furnace circuit board into the clamping groove 10 on one side of the fixing block 6. Then, rotating the knob 14 will drive the second bevel gear 13 to rotate via the rotating rod 12. Since the second bevel gear 13 meshes with the first bevel gear 11, the rotation of the second bevel gear 13 will drive the first bevel gear 11 to rotate, thereby driving the threaded shaft 8 to rotate. This causes the threaded shaft 8 to move the clamping block 9, bringing it closer to the vacuum furnace circuit board so that the other side of the circuit board can be placed into the clamping groove 10 on one side of the clamping block 9. Continuing to rotate the knob 14 will move the two clamping grooves 10... The circuit board is held firmly against both sides of the vacuum oven circuit board. Hot air can then be delivered to the baking oven 1 through the hot air pipe 20 via an external hot air blower, thereby increasing the internal temperature of the baking oven 1 and baking the vacuum oven circuit board. During the baking process, the drive motor 19 is turned on, which drives the rotating shaft 2 to rotate, thereby causing the two rotating blocks 3 to rotate 180 degrees. This allows the fixed vacuum oven circuit board to rotate 180 degrees as well, turning it over and baking the other side of the circuit board. This avoids uneven heating on both sides of the circuit board and improves baking efficiency.
