Technical Field

[0001] The utility model relates to the technical field of electronic manufacturing equipment, in particular to a material taking device for baking a PCB board. Background Art

[0002] A printed circuit board (PCB) is an essential component in electronic devices, used to support and connect various electronic components. During the manufacturing process of the PCB board, baking is required to remove the moisture inside the board to ensure its stability and reliability in subsequent processes. During the baking process, the PCB board is exposed to a high-temperature environment to evaporate the residual solvents and moisture inside, thereby improving its electrical performance and mechanical strength.

[0003] Currently, baking of PCB boards is usually carried out using large baking ovens. These baking ovens are internally provided with multiple layers of racks, and the PCB boards are placed layer by layer on the racks and then subjected to high-temperature baking. During the baking process, the temperature is precisely controlled to ensure that each PCB board is evenly heated to achieve the desired baking effect.

[0004] Although the existing baking equipment can effectively complete the baking task of PCB boards, there are still some inconveniences in actual operation. First, the high-temperature environment makes it difficult for operators to pick up and place PCB boards. For safety reasons, operators usually need to wear thick gloves, which not only reduces the flexibility of the fingers but also increases the complexity of the operation. Second, if the operator chooses to wait for the baking oven to cool down before taking the board, it will prolong the production cycle and affect the overall efficiency. Content of the Utility Model

[0005] In order to overcome the disadvantages of inconvenient manual material taking and low production efficiency, the utility model provides an efficient material taking device for baking a PCB board.

When material taking is required, the support frame is located in front of the baking machine, the material placing rack is located in the middle of the support frame, a material taking component for extending into the baking machine to take materials is arranged at the top of the support frame, the material taking component is in limiting cooperation with the limiting blocks, and the first controller is used to control the operation of the material taking component.

[0007] In one embodiment, the material taking assembly includes a moving frame, which is slidably connected to the top of the support frame. The moving frame is in limit cooperation with the limit block. Motors are installed at both the left and right ends of the top of the moving frame. Driving wheels and driven wheels are rotatably connected to both the left and right ends of the bottom of the moving frame. The driving wheels are connected to the output shafts of the motors, and the driving wheels and the driven wheels are in rolling connection with the support frame. Longitudinal electric slide rails are connected to both the left and right ends at the rear of the moving frame. A transverse electric slide rail is arranged between the two longitudinal electric slide rails. Two clamping plates are slidably connected to the lower end of the transverse electric slide rail. The clamping plates are in pressing cooperation with the PCB board. The first controller is wiredly connected to the motor, the longitudinal electric slide rail, and the transverse electric slide rail respectively.

Specific embodiments

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present utility model are not limited.

[0021] Embodiment: A material taking device for baking PCB boards, as Figures 1-4 shown, includes a baking machine 1, a support frame 2, a limit block 21, a first controller 22, universal wheels 3, a material placing rack 4 and a material taking assembly. Four universal wheels 3 are installed at the bottom of the support frame 2, a first controller 22 is installed on the front side of the support frame 2, limit blocks 21 are connected to both the front and rear ends of the top of the support frame 2. When material taking is required, the support frame 2 is located in front of the baking machine 1, the material placing rack 4 is located in the middle of the support frame 2, and a material taking assembly for extending into the baking machine 1 to take materials is provided at the top of the support frame 2. The material taking assembly is in limit cooperation with the limit block 21, and the first controller 22 is used to control the operation of the material taking assembly.

[0022] As Figures 2-4 shown, the material taking assembly includes a moving rack 5, a motor 6, a driving wheel 7, a driven wheel 8, a longitudinal electric slide rail 9, a transverse electric slide rail 10 and a clamping plate 11. The moving rack 5 is slidably connected to the top of the support frame 2, and the limit block 21 is used to limit the moving range of the moving rack 5. The moving rack 5 is in limit cooperation with the limit block 21. Motors 6 are installed at both the left and right ends of the top of the moving rack 5, and a driving wheel 7 and a driven wheel 8 are rotatably connected to both the left and right ends of the bottom of the moving rack 5. The driving wheel 7 is connected to the output shaft of the motor 6, and the driving wheel 7 and the driven wheel 8 are in rolling connection with the support frame 2. One driving wheel 7 and one driven wheel 8 form a group and sandwich the support frame 2 from both sides. Longitudinal electric slide rails 9 are connected to both the left and right ends of the rear side of the moving rack 5, a transverse electric slide rail 10 is provided between the two longitudinal electric slide rails 9. The transverse electric slide rail 10 is connected to the moving member of the longitudinal electric slide rail 9. Two clamping plates 11 are slidably connected to the lower end of the transverse electric slide rail 10. The clamping plates 11 are connected to the moving member of the transverse electric slide rail 10. The clamping plates 11 are in extrusion cooperation with the PCB board. The first controller 22 is wired to the motor 6, the longitudinal electric slide rail 9 and the transverse electric slide rail 10 respectively.

[0023] As Figure 1As shown in the figure, it also includes a mounting bracket 12, a fan 13, and a second controller 14. Mounting brackets 12 are connected to both the left and right sides of the support frame 2. Six fans 13 are installed in the mounting brackets 12, and a second controller 14 is installed on the front side of the support frame 2. The second controller 14 is wired to all the fans 13.

[0024] As Figure 1 shown in the figure, it also includes a handle 15. Handles 15 are connected to the front and rear parts of both the left and right sides of the support frame 2. By holding the handles 15 on both sides of the support frame 2, the support frame 2 can be easily pushed to move, improving the convenience of operation.

[0025] As Figure 1 shown in the figure, it also includes a buffer pad 16. A buffer pad 16 is connected to the contact part between the moving frame 5 and the limit block 21. The buffer pad 16 is used to reduce the impact force when the moving frame 5 contacts the limit block 21, protecting the connection stability between the limit block 21 and the moving frame 5.

[0026] As Figure 1 shown in the figure, it also includes a protective net 17. A protective net 17 is connected to the separated sides of the two mounting brackets 12.

[0027] As Figure 4 shown in the figure, it also includes a protective pad 18. Protective pads 18 are connected to the sides of the two clamping plates 11 that contact the PCB board. When the clamping plates 11 clamp the PCB board, the protective pads 18 play a buffering role and can also increase the friction between the clamping plates 11 and the PCB board, preventing the PCB board from slipping during the movement process and ensuring the stability and reliability of the material taking process.

[0028] After the baking of the PCB board is completed, open the door of the baking machine 1. The staff push the support frame 2 close to the baking machine 1. The universal wheels 3 facilitate the movement of the support frame 2. It is more convenient to move the support frame 2 through the handle 15, and the round-tube-shaped handle 15 is more comfortable to hold. Then, place the material rack 4 in the middle of the support frame 2. Fix the position of the support frame 2 through the locking device of the universal wheels 3 to ensure the stability of the support frame 2 during the material taking process. Then, start the motor 6, the horizontal electric slide rail 10 and the vertical electric slide rail 9 through the first controller 22. The motor 6 drives the driving wheel 7 to rotate. The driving wheel 7 is in rolling connection with the support frame 2, so as to drive the moving frame 5 to move backward. The driven wheel 8 moves accordingly to maintain the stability of the moving frame 5. The moving frame 5 drives the vertical electric slide rail 9 to move into the baking machine 1. The vertical electric slide rail 9 adjusts the height of the horizontal electric slide rail 10 in the vertical direction. The limiting blocks 21 are arranged front and back to limit the moving position of the moving frame 5. At the same time, the buffer pad 16 can play a buffering role when the moving frame 5 contacts the limiting block 21, reducing the hard contact between the moving frame 5 and the limiting block 21 and ensuring the stable connection of the limiting block 21. At the same time, according to the position of the PCB board, the vertical electric slide rail 9 drives the horizontal electric slide rail 10 to move up and down. When the clamping plates 11 are located on the left and right sides of the PCB board, the horizontal electric slide rail 10 drives the two clamping plates 11 to move towards the middle and clamp the PCB board. Then, the motor 6 rotates in reverse, the horizontal electric slide rail 10 remains stationary, and the vertical electric slide rail 9 drives the horizontal electric slide rail 10 to reset. Finally, the PCB board is located on the top of the material rack 4. At this time, the vertical electric slide rail 9 drives the horizontal electric slide rail 10 to move downward, and the horizontal electric slide rail 10 releases the PCB board to complete the material taking. Then, repeat the above operations to complete the material taking work of all PCB boards in the baking machine 1, and turn off the motor 6, the vertical electric slide rail 9 and the horizontal electric slide rail 10;

[0029] During the discharging of the PCB board, start the fan 13 through the second controller 14. The fans 13 on both sides blow air towards the middle, so as to accelerate the cooling of the PCB board. After the material taking is completed, it can directly enter the next step, reducing the waiting time and improving the production efficiency. The protective net 17 is installed on the outside of the mounting frame 12 to prevent the staff from contacting the blades of the fan 13 and ensure the operation safety. When the clamping plate 11 contacts the PCB board, the protective pad 18 can play a buffering role to prevent the PCB board from being damaged by hard extrusion. At the same time, the protective pad 18 increases the friction between the clamping plate 11 and the PCB board, optimizes the clamping and fixing effect, and prevents the PCB board from slipping during the movement.

[0030] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
