Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a 3D printing worktable with heat dissipation function. Background Technology

[0002] During 3D printing, the printing material melts and accumulates layer by layer under the high temperature of the nozzle. After printing, removing the PEI plate usually requires manual operation. In batch printing, if the user does not remove the PEI plate in time, it will waste a lot of time. At the same time, the PEI plate needs a certain amount of time to cool down, making it impossible to quickly remove the printed parts from the PEI plate. Utility Model Content

[0003] The main purpose of this invention is to provide a 3D printing workbench with heat dissipation function, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a 3D printing worktable with heat dissipation function, including a printer and a Y-axis, a heated bed mechanism is provided at the output end of the Y-axis, a material picking mechanism is provided at the rear side of the heated bed mechanism, a material box is provided at the rear side of the printer, a PEI plate is provided inside the material box, a hook plate is provided at the front center of the PEI plate, and a lifting mechanism is provided at the front of the printer;

[0005] The heated bed mechanism includes a magnetic heated bed, a heat dissipation vent, a fan, and a connecting platform. The lower center of the connecting platform is located at the Y-axis output end. The four corners of the magnetic heated bed are connected to the connecting platform via leveling nuts. The fan is installed in the middle of the left and right sides of the connecting platform, and the heat dissipation vent is located in the middle of the magnetic heated bed.

[0006] Preferably, guide plates are provided on the left and right sides of the magnetic heating bed.

[0007] Preferably, the material handling mechanism includes a tail plate, a locking block, and a servo motor. The lower end of the locking block is rotatably connected to the lower middle part of the rear side of the tail plate. The servo motor is installed on the rear right side of the tail plate, and the output end of the servo motor passes through the tail plate and is fixedly connected to the lower part of the locking block.

[0008] Preferably, the side of the hook plate is shaped like a "7".

[0009] Preferably, the lifting mechanism includes a lifting assembly and a shaft, with the left and right ends of the shaft rotatably connected to the upper end of the lifting assembly, and the lower part of the lifting assembly fixedly connected to the left and right sides of the front of the printer.

[0010] Preferably, the lifting mechanism includes a limiting sleeve, a connecting box, a limiting rod, gears, and a motor. The lower end of the limiting sleeve is fixedly connected to the front of the printer. One end of the connecting box is fixedly connected to the upper end of the limiting sleeve. The lower end of the limiting rod passes through the connecting box and is slidably connected inside the limiting sleeve. The two gears mesh with each other and are rotatably connected inside the connecting box. The middle part of one of the gears is threadedly connected to the outer periphery of the limiting rod. The motor is installed on the upper part of the other end of the connecting box. The lower output end of the motor passes through the connecting box and is fixedly connected to the middle part of the other gear.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. After printing is complete, drive the fan to quickly cool the magnetic heated bed and PEI board, making it easy to remove the printed parts from the PEI board.

[0013] 2. After printing is complete, move the heated bed mechanism forward, then drive the motor to move the limit rod upward relative to the limit sleeve. This causes the shaft to lift the front of the PEI plate above the heated bed mechanism, hooking the hook plate in front of the PEI plate. Next, move the heated bed mechanism backward, extending the tail plate under the material box. Then drive the servo motor to raise the locking block, hooking the hook plate of the lowest PEI plate inside the material box. Drive the heated bed mechanism forward, causing the PEI plate at its front to move continuously. With the lifting mechanism, the PEI plate at the front of the heated bed mechanism gradually separates from it, eventually sliding forward from the lifting mechanism. At this point, the tail of the PEI plate dragged out by the rear of the heated bed mechanism is at the front of the material box. When the heated bed mechanism moves backward, the PEI plate at the rear is blocked by the material box and cannot move. When the heated bed mechanism moves to the PEI plate... When the PEI plate is below the heated bed, it will be magnetically attached to the heated bed mechanism, thus completing the automatic replacement of the PEI plate without manual intervention, saving a lot of time.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As shown in Figures 1-4, a 3D printing workbench with heat dissipation function includes a printer 1 and a Y-axis. A heated bed mechanism 2 is provided at the output end of the Y-axis. A material picking mechanism 4 is provided behind the heated bed mechanism 2. A material box 5 is provided behind the printer 1. A PEI plate 6 is provided inside the material box 5. A hook plate 7 is provided in the middle of the front side of the PEI plate 6. A lifting mechanism 3 is provided at the front of the printer 1.

[0022] In this embodiment, the heated bed mechanism 2 includes a magnetic heated bed 201, a heat dissipation port 202, a fan 203, and a connecting platform 204. The lower center of the connecting platform 204 is located at the Y-axis output end. The four corners of the magnetic heated bed 201 are connected to the connecting platform 204 through leveling nuts. The fan 203 is installed in the middle of the left and right sides of the connecting platform 204. The heat dissipation port 202 is opened in the middle of the magnetic heated bed 201. Guide plates 205 are provided on the left and right sides of the magnetic heated bed 201.

[0023] Specifically, after printing is completed, the fan 203 is driven to quickly cool the magnetic heated bed 201 and the PEI plate 6, making it easy to remove the printed parts from the PEI plate 6.

[0024] In this embodiment, the material handling mechanism 4 includes a tail plate 401, a locking block 402, and a servo motor 403. The locking block 402

[0025] The lower end is rotatably connected to the lower middle part of the rear side of the tailplate 401, and the servo 403 is installed on the rear right side of the tailplate 401.

[0026] The output end of the servo motor 403 passes through the tail plate 401 and is fixedly connected to the lower part of the latch block 402. The side of the hook plate 7 is shaped like a "7". The lifting mechanism 3 includes a lifting assembly and a shaft 306. The left and right ends of the shaft 306 are rotatably connected to the upper end of the lifting assembly. The lower part of the lifting assembly is fixedly connected to the left and right sides of the front of the printer 1. The lifting mechanism 3 includes a limiting sleeve 301, a connecting box 302, a limiting rod 303, gears 304, and a motor 305. The lower end of the limiting sleeve 301 is fixedly connected to the front of the printer 1. One end of the connecting box 302 is fixedly connected to the upper end of the limiting sleeve 301. The lower end of the limiting rod 303 passes through the connecting box 302 and is slidably connected inside the limiting sleeve 301. Two gears 304 mesh with each other and are rotatably connected inside the connecting box 302. The middle part of one gear 304 is threadedly connected to the outer circumference of the limiting rod 303. The motor 305... Installed on the upper part of the other end of the connecting box 302, the lower output end of the motor 305 passes through the connecting box 302 and is fixedly connected to the middle of another gear 304.

[0027] Specifically, after printing is completed, the heated bed mechanism 2 is moved forward, and then the drive motor 305 is activated, causing the limiting rod 303 to move upward relative to the limiting sleeve 301. This causes the shaft 306 to lift the front of the PEI plate 6 above the heated bed mechanism 2, so that the hook plate 7 in front of the PEI plate 6 is hooked by the shaft 306. Then, the heated bed mechanism 2 is moved backward, so that the tail plate 401 extends under the material box 5. Then, the servo motor 403 is activated, causing the locking block 402 to stand up, thereby hooking the hook plate 7 of the PEI plate 6 at the bottom inside the material box 5. Then, the heated bed mechanism 2 is driven forward, causing the heated bed mechanism 2 to continuously move the PEI plate 6 at its front end. Under the lifting of the lifting mechanism 3, the PEI plate 6 at the front of the heated bed mechanism 2 gradually separates from the heated bed mechanism 2, so that it finally leaves the lifting mechanism 3. As the PEI plate 6 slides forward, its tail end, which is pulled out from the rear of the heated bed mechanism 2, is located in front of the material box 5. When the heated bed mechanism 2 moves backward, the PEI plate 6 at the rear of the heated bed mechanism 2 is blocked by the material box 5 and cannot move. When the heated bed mechanism 2 moves under the PEI plate 6, the PEI plate 6 will be magnetically attracted to the heated bed mechanism 2, thus completing the automatic replacement of the PEI plate 6 without manual intervention, saving a lot of time.

[0028] Working principle:

[0029] After printing, the fan 203 is driven to quickly cool the magnetic heated bed 201 and PEI plate 6, facilitating the removal of the printed parts from the PEI plate 6. After printing, the heated bed mechanism 2 is moved forward, and then the motor 305 is driven to move the limiting rod 303 upward relative to the limiting sleeve 301, causing the shaft 306 to lift the PEI plate 6 above the heated bed mechanism 2, so that the hook plate 7 is hooked by the shaft 306. Then, the heated bed mechanism 2 is moved to the rear, so that the tail plate 401 extends under the material box 5. Then, the servo motor 403 is driven to raise the locking block 402, so that the locking block 402 hooks the hook plate 7 of the PEI plate 6 at the bottom inside the material box 5. Then, the heated bed mechanism 2 is driven to move forward, so that the heated bed mechanism 2 drives the PEI plate 6 at its front end to move continuously. Under the lifting mechanism 3, the PEI plate 6 at the front of the heated bed mechanism 2... Gradually separating from the heated bed mechanism 2, the PEI plate 6 is eventually slid forward from the lifting mechanism 3. At this time, the tail of the PEI plate 6 dragged out from the rear of the heated bed mechanism 2 is located in front of the material box 5. When the heated bed mechanism 2 moves backward, the PEI plate 6 at the rear of the heated bed mechanism 2 is blocked by the material box 5 and cannot move. When the heated bed mechanism 2 moves under the PEI plate 6, the PEI plate 6 will be magnetically attracted to the heated bed mechanism 2, thereby completing the automatic replacement of the PEI plate 6 without manual intervention, saving a lot of time.
