[0027] Example:

The drive wheel 10 and the driven wheel 11 are connected by transmission belt 12. The drive wheel 10 is connected to the output shaft of the third motor 23.

[0036] The second robotic arm 3 includes a horizontal displacement mechanism 13, a vertical displacement mechanism 14, and a second clamp 15. The second clamp 15 is mounted on the vertical displacement mechanism 14. The vertical displacement mechanism 14 is used to drive the second clamp 15 to move in the vertical direction. The vertical displacement mechanism 14 is connected to the horizontal displacement mechanism 13. The horizontal displacement mechanism 13 is used to drive the vertical displacement mechanism 14 and the second clamp 15 to move in a direction perpendicular to the running direction of the transport mechanism 4.

[0037] The second clamp 15 includes a crossbeam 16, a first clamping plate 17 and a second clamping plate 18. The first clamping plate 17 is fixed to one side of the crossbeam 16, and the second clamping plate 18 is movably disposed on the other opposite side of the crossbeam 16 via a telescopic member.

[0038] Clamping blocks are respectively provided on the side of the first clamping plate 17 and the second clamping plate 18 that are close to each other;

[0039] The telescopic component is a cylinder, a hydraulic cylinder, or an electric push rod. In this embodiment, it is a cylinder.

[0040] The horizontal displacement mechanism 13 includes a slider 19 and a slide rail 20 mounted on the frame 1. The slider 19 is slidably mounted on the slide rail 20, and the vertical displacement mechanism 14 is connected to the slider 19. The slide rail 20 is mounted on a vertical support 9, and a rectangular support frame 22 is mounted on the horizontal displacement mechanism 13. The bottom of the support frame 22 is fixed to the slider 19. A rack is mounted on the side of the slide rail 20, and a gear is mounted on the side of the support frame 22 that meshes with the rack. The gear is connected to the output shaft of a drive motor, thereby driving the horizontal displacement mechanism 13.

[0041] The vertical displacement mechanism 14 includes a vertical beam 21 and a rectangular support frame 22. The support frame 22 is equipped with a fourth motor 24. The output shaft of the fourth motor 24 is horizontally positioned and connected to a drive gear. The vertical beam 21 is equipped with a vertical rack 25 that meshes with the drive gear. To improve stability, a sliding block can be provided inside the support frame 22, and tracks that slide and engage with the sliding block can be provided on both sides of the vertical beam 21, thereby limiting and guiding the movement through the sliding block and the tracks.

[0042] The support platform 5 includes a rectangular frame 26, a rotating shaft, and a base 28. The rotating shaft is rotatably mounted on the base 28. A gear ring 27 is provided on the outside of the rotating shaft. The rectangular frame 26 is mounted on the rotating shaft. A fifth motor is also provided on the base 28. The output shaft of the fifth motor is provided with a drive gear that meshes with the gear ring 27.

[0043] Among them, 1. A circular brick-making machine, with each brick-making station arranged in a circle. 2. The first robotic arm 2 includes a crossbar (with the same structure as the crossbeam 16, but smaller in size), two clamping plates, and two micro cylinders. The clamping plates are slidably connected to the crossbar and can slide along the length of the crossbar. The cylinder body of the micro cylinder is set on the crossbar, and the piston rod of the micro cylinder is connected to the clamping plate (upper side). The lower part of the clamping plate is used to clamp the bricks. The two micro cylinders are used to drive the two clamping plates to move closer or further apart, thereby realizing the action of clamping and releasing the bricks.

[0044] Working principle: (1) Action of the first manipulator 2: The first clamp 6 corresponds to the formed brick on the brick making machine. When the formed brick rotates to the first clamp 6, the two clamping plates of the first clamp 6 approach each other and clamp the brick. After the brick is clamped, the output shaft of the first motor 7 rotates 90 degrees. This process drives the first clamp 6 to rotate 90 degrees, thereby making the brick stand up (standing up means: the plane formed by the length and width as the bottom surface changes to the plane formed by the length and height as the bottom surface).

[0045] After the bricks are erected, the output shaft of the second motor 8 rotates 90 degrees, driving the first motor 7 and the first clamp 6 to rotate 90 degrees horizontally until they align with the transport mechanism.

[0046] (2) Transport mechanism: When the first clamp 6 is released, the bricks automatically fall onto the transmission belt 12. If no bricks fall onto the transmission belt 12, the transmission belt 12 moves forward a distance, which is the width of the bricks. When the bricks accumulate to 19 in this embodiment, the second clamp 15 clamps the bricks.

[0047] (3) The second manipulator 3 operates as follows: the second clamp 15 operates to clamp the brick: the telescopic component moves the second clamp 18 toward the first clamp 17, thereby reducing the distance between the two and clamping the brick.

[0048] After the bricks are clamped, they are lifted by the vertical displacement mechanism 14 until they are disengaged from the transmission belt. Then, they are moved to the top of the pallet by the horizontal displacement mechanism 13 and then lowered by the vertical displacement mechanism 14. Once the bricks are on the pallet, the second clamp 15 is released, and the stacking is completed. After each stacking is performed four times (i.e., after the second robotic arm 3 moves four times), the pallet rotates 90 degrees to ensure that the bricks in each layer are perpendicular to each other.

[0049] This invention enables automatic stacking of unfired bricks after they have been formed by setting up two sets of robotic arms, a transport mechanism, and a turntable. At the same time, it ensures that the bricks in each layer are perpendicular to each other, and the mechanical stacking greatly improves the stacking efficiency.
