The robotic arm was the earliest industrial robot and also the earliest modern robot. It can replace heavy human labor to realize the mechanization and automation of production. It can operate in hazardous environments to protect personal safety. Therefore, it is widely used in machinery manufacturing, metallurgy, electronics, light industry, and nuclear energy sectors. Existing flat robotic arms are usually fixed at the installation station and cannot achieve long-distance movement and adjustment, which limits their scope of use. Utility Model Content

Two L-shaped brackets 42 are symmetrically installed on the surface of the lower plate 1. A driven gear 43 is rotatably installed between the two L-shaped brackets 42. The drive gear 41 and the driven gear 43 are meshed and connected. Auxiliary gears 44 are meshed and connected on both sides of the driven gear 43. A T-shaped groove 45 is opened at the bottom of the middle plate 2. A rack 46 is fixedly installed in the middle of the T-shaped groove 45 and meshes and connects with the driven gear 43.
[0024] In practical use: A drive gear 41 is installed at the bottom of the lower plate 1. The drive gear 41 rotates and meshes with the driven gear 43 rotatably connected between the two L-shaped brackets 42, thereby driving the driven gear 43 to rotate. The driven gear 43 rotates and meshes with the rack 46 installed inside the T-shaped groove 45 at the bottom of the middle plate 2, thereby driving the middle plate 2 to move. Auxiliary gears 44 are meshed and connected on both sides of the driven gear 43. When the driven gear 43 drives the rack 46 to move left and right, the rack 46 meshes with the auxiliary gears 44 on both sides to ensure the sliding stability of the middle plate 2.
[0025] Please see Figure 1 , Figure 3 The transmission assembly 5 includes a first chain 51 fixedly installed on both sides of one end of the lower plate 1, and a second chain 52 fixedly installed on both sides of the other end of the lower plate 1. The top of the middle plate 2 has mounting holes 53 at both ends, and mounting sprockets 54 are rotatably installed inside the mounting holes 53 at both ends. The two mounting sprockets 54 are arranged in opposite directions. The first chain 51 is engaged with one of the mounting sprockets 54 and its other end is fixedly connected to the inner wall of one end of the upper plate 3. The second chain 52 is engaged with the other mounting sprocket 54 and its other end is fixed to the inner wall of the other end of the upper plate 3.
[0026] In practical use: A first chain 51 is installed on both sides of one end of the lower plate 1, and a second chain 52 is fixedly installed on both sides of the other end. Mounting holes 53 are opened at both ends of the middle plate 2. Mounting sprockets 54 are rotatably installed inside the mounting holes 53. One end of the first chain 51 is engaged with one of the mounting sprockets 54 and the other end is fixed to one end of the upper plate 3. The second chain 52 is engaged with the other mounting sprocket 54 and the other end is connected to the inner wall of the other end of the upper plate 3. When the middle plate 2 moves left and right, the first chain 51 and the second chain 52 drive the upper plate 3 to move accordingly. Under the drive of the second chain 52, the upper plate 3 slides along the middle plate 2, thereby extending and unfolding the lower plate 1, the middle plate 2 and the upper plate 3 in a stepped shape, increasing the stroke of the flatbed robot and improving the range of use.
[0027] Please see Figure 2 , Figure 3 Multiple rollers 6 are rotatably installed on the top outer side of the two L-shaped brackets 42.

Pulleys 8 are rotatably installed on both sides of the inner wall of the upper plate 3. The pulleys 8 slide inside the slide grooves 7.
[0028] In practical use: Multiple rollers 6 are rotatably installed on the top outer side of the two L-shaped brackets 42. The rollers 6 roll on both sides of the inner wall of the T-shaped groove 45. When the middle layer plate 2 moves, the rollers 6 play a limiting and guiding role to ensure that the middle layer plate 2 slides stably relative to the lower layer plate 1. The middle layer plate 2 has sliding grooves 7 on both sides. The inner walls of the upper layer plate 3 slide in the sliding grooves 7 through the pulleys 8, so that the upper layer plate 3 slides stably along the middle layer plate 2.
[0029] Please see Figure 2 , Figure 3 Both sides of the surface of the lower plate 1 and the middle plate 2 are provided with chain guide rails 9, and the first chain 51 and the second chain 52 are both set inside the chain guide rails 9.
[0030] In practical use: chain guide rails 9 are installed on the surfaces of the lower plate 1 and the middle plate 2. The first chain 51 and the second chain 52 are respectively set inside the chain guide rails 9, so that the chain maintains linear movement in a restricted manner during the movement process, and prevents the first chain 51 and the second chain 52 from swinging and deviating, causing jamming.
[0031] Please see Figure 2 , Figure 3 A drive shaft 10 is mounted in the middle of the drive gear 41, and a drive sprocket 11 is fixedly mounted at one end of the drive shaft 10.
[0032] In practical use: A drive shaft 10 is installed in the middle of the drive gear 41, and a drive sprocket 11 is installed at one end of the drive shaft 10. The drive sprocket 11 is connected to an external power source to drive the drive gear 41 to drive the equipment.
[0033] Please see Figure 1 , Figure 4 Multiple mounting brackets 12 are fixedly installed on one side of the lower plate 1, and a proximity sensor 13 is fixedly installed on the top of the mounting bracket 12.
[0034] In practical use: multiple fixing brackets 12 are installed on one side of the lower plate 1, and proximity sensors 13 installed on the top of the fixing brackets 12 are used to detect the movement position of the middle plate 2 and the upper plate 3.
[0035] Please see Figure 1 , Figure 3 The lower plate 1, the middle plate 2, and the upper plate 3 are all made of stainless steel.
[0036] In practical use: the lower plate 1, the middle plate 2 and the upper plate 3 are made of stainless steel. After the materials are processed, they are subjected to vacuum constant temperature and constant pressure degassing treatment to ensure that the structural components can be used in high and low temperature vacuum environments and to guarantee the service life of the structural components.
[0037] A first chain 51 is installed on both sides of one end of the lower plate 1, and a second chain 52 is fixedly installed on both sides of the other end. Mounting holes 53 are opened at both ends of the middle plate 2, and mounting sprockets 54 are rotatably installed inside the mounting holes 53. One end of the first chain 51 is engaged with one of the mounting sprockets 54 and the other end is fixed to one end of the upper plate 3. The second chain 52 is engaged with the other mounting sprocket 54 and the other end is connected to the inner wall of the other end of the upper plate 3. When the middle plate 2 moves left and right, the first chain 51 and the second chain 52 drive the upper plate 3 to move accordingly. Under the drive of the second chain 52, the upper plate 3 slides along the middle plate 2, thereby extending and unfolding the lower plate 1, the middle plate 2 and the upper plate 3 in a stepped shape, increasing the stroke of the flatbed robot and improving the range of use.
