Description

Technical Field

[0001] This application relates to the field of brick-making equipment, and in particular to a sintered brick blank stacking machine. Background Technology

[0002] Before firing bricks, the brick blanks need to be stacked into brick piles, and then the brick piles are pushed into the kiln for firing so that more bricks can be fired in one kiln.

[0003] In order to reduce the workload of workers, brick stacking machines are now commonly used to pick up bricks and place them in designated positions.

[0004] The existing brick-making process for sintered bricks typically involves first extruding brick blanks into segments using an extruder, and then cutting the segments into brick blanks of the required size using a wire cutter. However, the gaps between the brick blanks formed after wire cutting are very small, and when the brick blank stacking machine picks up the brick blanks, it directly picks up the segments and stacks them directly. This results in the gaps between the brick blanks in the stacked brick pile being too small, which is not conducive to the brick pile being fired thoroughly and also makes it easy for the fired bricks to stick together.

[0005] Therefore, there is a need for a brick blank clamping assembly and a sintered brick blank stacking machine. Summary of the Invention

[0006] In order to improve the problem that the small gap between brick blanks during stacking is not conducive to the thorough firing of the brick pile and also makes the fired bricks stick together, this application provides a brick blank clamping component and a sintered brick blank stacking machine.

[0007] The first aspect of this application provides a brick blank clamping assembly, which adopts the following technical solution: A brick blank clamping assembly includes a support frame unit, a gripper unit disposed on the support frame unit, and a scissor adjustment unit. The support frame unit includes a track rod and a connecting rod. The gripper unit includes multiple support rods and clamping plates disposed at both ends of each support rod and a clamping drive component.

[0008] The clamping plates at both ends of the support rod can move closer or further apart under the drive of the clamping drive. Each support rod is mounted on the track rod and can move along the track rod. One end of the connecting rod is connected to the track rod, and the other end is used to connect to the robotic arm. Each support rod is also connected to the scissor lift adjustment unit to adjust the gap between two adjacent support rods via the scissor lift adjustment unit.

[0009] By adopting the above technical solution, clamping plates and clamping drive components are set at both ends of the support rod, so that each support rod can clamp a row of brick blanks. Furthermore, the gap between the two support rods can be adjusted by the scissor adjustment unit, thereby adjusting the spacing between each row of brick blanks to ensure that there is a certain gap in the stacked bricks, which facilitates the heat to enter the middle of the brick stack, which is conducive to the thorough firing of the bricks and can reduce the sticking of the fired bricks.

[0010] Furthermore, the track rod is configured as two rods, each of which is connected to one end of the connecting rod, and the connecting rod is connected to the middle of the track rod.

[0011] By adopting the above technical solution, the support frame unit can have higher strength, and the support rod can be more stable when moving on the track rod.

[0012] Furthermore, the gripper unit also includes a guide slide seat, which includes a first track flange plate, a second track flange plate, track flange plate connecting bolts, and a guide roller. The first track flange plate is provided with connecting ears to connect to the support rod. Both the first and second track flange plates are provided with matching flange connection holes. The track flange plate connecting bolts pass sequentially through the flange connection holes on the first and second track flange plates and are connected with nuts to achieve the connection between the first and second track flange plates. A track receiving cavity suitable for accommodating the track rod is formed between the first and second track flange plates. The guide roller is rotatably connected to the side of the second track flange plate facing the track rod, and the axial direction of the guide roller is perpendicular to the length direction of the track rod.

[0013] By adopting the above technical solution, the guide sliding seat can guide and limit the support rod, making the support rod more stable when moving on the track rod. In addition, the guide roller can reduce the friction between the guide sliding seat and the track rod, making it easier for the support rod to move on the track rod.

[0014] Furthermore, each of the two ends of the support rod is provided with a set of clamping plates and clamping drive components; the clamping plates are hinged to the ends of the support rods, and the clamping plates include a drive part and a clamping part; the clamping drive components are located at the ends of the support rods, and the clamping drive components are drive cylinders, the telescopic rods of the drive cylinders are connected to the drive section of the clamping plates, so that the clamping plates can be rotated via the drive cylinders, causing the clamping parts on the clamping plates arranged opposite to each other at both ends of the support rods to move closer or further apart.

[0015] By adopting the above technical solution, the brick blank can be clamped when the clamping parts on the clamping plates arranged opposite to the two ends of the support rod are close to each other, and the brick blank can be released when the clamping parts on the clamping plates arranged opposite to the two ends of the support rod are far apart.

[0016] Furthermore, the scissor lift adjustment unit includes a plurality of scissor lifts, a telescopic adjuster, and a rod end sliding seat. Two scissor lifts are provided between each pair of adjacent support rods, and the middle portions of the two scissor lifts are hinged together. Each support rod is provided with a rod end fixing seat, and the rod end sliding seat is sleeved on the support rod and can move along the support rod. One end of each scissor lift is hinged to the rod end fixing seat on one of the two support rods, and the other end of each scissor lift is hinged to the rod end sliding seat on the other of the two support rods. Both ends of the telescopic adjuster are respectively connected to the rod end fixing seat and the rod end sliding seat on the same support rod. The telescopic adjuster can move the rod end sliding seat closer to or away from the rod end fixing seat, so that when the rod end sliding seat is close to the rod end fixing seat, adjacent support rods move away from each other, and when the rod end sliding seat is away from the rod end fixing seat, adjacent support rods move closer to each other.

[0017] By adopting the above technical solution, the spacing between adjacent support rods can be adjusted by extending and retracting the telescopic adjuster. This results in a smaller spacing between adjacent support rods when clamping brick blanks, making it easier to clamp multiple rows of closely arranged brick blanks. When the brick blanks are moved to the designated stacking area, the spacing between adjacent support rods is increased, thereby enabling the brick blanks to be stacked sparsely. This makes it easier for the stacked bricks to be fired thoroughly in the kiln and prevents the bricks from sticking together.

[0018] Furthermore, the rod end fixing seat is fixedly connected to the support rod, and the rod end fixing seat is provided with a fixing seat hinge shaft, the end of the scissor bar can be hinged to the fixing seat hinge shaft; the rod end sliding seat includes a first sliding flange plate, a second sliding flange plate, sliding flange plate connecting bolts, and a sliding roller; the first sliding flange plate is provided with a flange plate hinge shaft, the end of the scissor bar can be hinged to the flange plate hinge shaft, both the first sliding flange plate and the second sliding flange plate are provided with matching flange connection holes, the sliding flange plate connecting bolts pass sequentially through the flange connection holes on the first sliding flange plate and the second sliding flange plate and are connected with nuts to realize the connection between the first sliding flange plate and the second sliding flange plate, and a receiving cavity suitable for accommodating the support rod is formed between the first sliding flange plate and the second sliding flange plate; the sliding roller is rotatably connected to the side of the first sliding flange plate facing the support rod, and the axial direction of the sliding roller is perpendicular to the length direction of the support rod.

[0019] By adopting the above technical solution, the rod end fixing seat can limit one end of the scissor bar, while the rod end sliding seat can facilitate the other end of the scissor bar to move along the support rod to achieve deformation adjustment.

[0020] Furthermore, the scissor bar is longer the closer it is to the middle of the track bar.

[0021] By adopting the above technical solution, the deformation of the pair of scissor bars closer to the middle of the track pole is greater. This allows for a larger gap between the two support bars closer to the middle of the track pole when adjusting the spacing between adjacent support bars. Consequently, the gap between the parts of the stacked bricks closer to the core is larger, making the bricks easier to burn through.

[0022] Furthermore, each of the first sliding flange plates is provided with two flange plate hinge shafts, and the line connecting the two flange plate hinge shafts is inclined in the direction from near the middle of the track rod to away from the middle of the track rod, along the direction from away from the middle of the support rod to near the middle of the support rod; each of the fixed seats is also provided with two fixed seat hinge shafts, and the line connecting the two fixed seat hinge shafts is inclined in the direction from near the middle of the track rod to away from the middle of the track rod, along the direction from away from the middle of the support rod to near the middle of the support rod. The direction of the part is inclined; one hinge end of one of the two scissor bars between two adjacent support bars is hinged to the fixed seat hinge axis on one support bar near the end of the support bar, and the other hinge end is hinged to the flange plate hinge axis on the other support bar near the fixed seat; one hinge end of the other of the two scissor bars is hinged to the flange plate hinge axis on one support bar away from the fixed seat, and the other hinge end is hinged to the fixed seat hinge axis on the other support bar away from the end of the support bar.

[0023] By adopting the above technical solution, it is easier to set the deformation of each set of scissor lifts, so that the deformation dimensions between adjacent sets of scissor lifts will not interfere with each other.

[0024] The second aspect of this application provides a sintered brick blank stacking machine, which adopts the following technical solution: A sintered brick blank stacking machine includes a rotating base, a rotating unit, and the brick blank clamping assembly described in the above technical solution, as well as a robotic arm. The robotic arm is disposed on the rotating base and connected to the brick blank clamping assembly via the rotating unit, so that the robotic arm can be driven to rotate in the vertical direction via the rotating base, the rotating unit can be driven to move in the horizontal and vertical directions via the robotic arm, and the brick blank clamping assembly can be driven to rotate in the vertical direction via the rotating unit.

[0025] By adopting the above technical solution, the brick blanks can be transferred through the rotating seat and the robotic arm, so that the brick blanks can be transferred to the set stacking area. The brick blanks can be stacked in an alternating and gapped manner through the rotating unit of the robotic arm and the brick blank clamping assembly, so that the stacked bricks are more solid and have gaps, making the bricks easier to fire through.

[0026] Furthermore, the robotic arm includes a first movable arm and a second movable arm. One end of the first movable arm is rotatably connected to the rotating seat, and the other end is rotatably connected to the second movable arm, so that the first movable arm can be driven to rotate in the vertical direction via the rotating seat, and the second movable arm can be driven to move in the horizontal and vertical directions via the first movable arm. The second movable arm is also rotatably connected to the rotating unit, so that the rotating unit can be driven to move in the horizontal and vertical directions via the second movable arm. During the rotation of the first movable arm and the second movable arm, the brick clamping assembly is in a horizontal state.

[0027] By adopting the above technical solution, it is possible to stack brick blanks in an alternating manner.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. The support rods are equipped with clamping plates and clamping drive components at both ends so that each support rod can clamp a row of brick blanks. Furthermore, the gap between the two support rods can be adjusted by the scissor adjustment unit, thereby adjusting the spacing between each row of brick blanks to ensure that there is a certain gap in the stacked bricks. This allows heat to enter the middle of the brick stack, which is beneficial for the bricks to be fired thoroughly and can reduce the sticking of the fired bricks.

[0030] 2. The rotating seat and robotic arm enable the transfer of brick blanks to a designated stacking area. The robotic arm rotating unit and brick blank clamping assembly enable the brick blanks to be stacked in an alternating and spaced manner, making the stacked bricks more solid and spaced, thus making the bricks easier to fire thoroughly.

[0038] Figure 1 This is a perspective view of a sintered brick blank stacking machine according to this application. See also: Figure 1 The first aspect of this application provides a brick blank clamping assembly including a support frame unit 1, a gripper unit 2 disposed on the support frame unit 1, and a scissor adjustment unit 3. The support frame unit 1 includes a track rod 11 and a connecting rod 12. The gripper unit 2 includes multiple support rods 21 and clamping plates 22 disposed at both ends of each support rod 21, as well as a clamping drive member 23.

[0039] The clamping plates 22 at both ends of the support rod 21 can move closer or further apart under the drive of the clamping drive 23. When the clamping plates 22 at both ends of the support rod 21 move closer together, the brick blank can be clamped. When the brick blank is clamped in place, the clamping plates 22 at both ends of the support rod 21 move further apart so that they can be in an open state and the brick blank can be placed in a set position. Each support rod 21 is mounted on the track rod 11 and can move along the track rod 11. One end of the connecting rod 12 is connected to the track rod 11, and the other end is used to connect to the robotic arm 4. Each support rod 21 is also connected to the scissor adjustment unit 3 so that the gap between two adjacent support rods 21 can be adjusted through the scissor adjustment unit 3, thereby increasing the gap between the brick blanks and reducing the situation where the brick blanks are connected together during brick firing.

[0040] Clamping plates 22 and clamping drive components 23 are set at both ends of the support rod 21 so that each support rod 21 can clamp a row of brick blanks. Furthermore, the gap between the two support rods 21 can be adjusted by the scissor adjustment unit 3, thereby adjusting the spacing between each row of brick blanks to ensure that there is a certain gap in the stacked bricks, so that heat can enter the middle of the brick stack, which is conducive to the thorough firing of the bricks and can reduce the sticking of the fired bricks.

[0041] like Figure 1 As shown, two track rods 11 can be configured, each of which is connected to one end of a connecting rod 12, and the connecting rod 12 is connected to the middle of the track rod 11. This allows the support frame unit 1 to have higher strength and makes the support rod 21 more stable when moving on the track rod 11. In addition, the connecting rod 12 can be placed on the upper part of the track rod 11 and the support rod 21 can be placed on the lower part of the track rod 11. This allows sufficient space to be formed between the connecting rod 12 and the support rod 21 to accommodate the scissor lift adjustment unit 3, and the scissor lift adjustment unit 3 can be placed between the connecting rod 12 and the support rod 21 without encroaching too much on the space below the support rod 21 used for clamping the brick blank.

[0042] Figure 2 yes Figure 1 Enlarged view of region A in the middle, as shown Figure 1 and Figure 2As shown, the gripper unit 2 also needs to include a guide slide seat 24. Specifically, the guide slide seat 24 includes a first track flange plate 241, a second track flange plate 242, track flange plate connecting bolts 243, and a guide roller 244. The first track flange plate 241 is provided with connecting ears so that it can be screwed to the support rod 21 via the connecting ears. Taking the track rod 11 as a square tube as an example, the first track flange plate 241 and the second track flange plate 242 can both be set as rectangular plates. The corners of the first track flange plate 241 and the second track flange plate 242 are provided with matching flange connection holes. The track flange plate connecting bolts 243 can pass through the flange connection holes on the first track flange plate 241 and the second track flange plate 242 in sequence and be connected with nuts to realize the first track flange plate 241 connecting to the support rod 21 via the connecting ears. The connection between the first track flange plate 241 and the second track flange plate 242, and the formation of a track receiving cavity between the first track flange plate 241 and the second track flange plate 242 to accommodate the track rod 11, allows the guide sliding seat 24 to be sleeved on the track rod 11, thereby realizing the connection between the support rod 21 and the track rod 11, and providing a limiting and guiding function for the movement of the support rod 21 on the track rod 11; in addition, the guide roller 244 is rotatably connected to the side of the second track flange plate 242 facing the track rod 11, and the axial direction of the guide roller 244 is perpendicular to the length direction of the track rod 11, so that the support rod 21 and the track rod 11 are rolled together by the guide roller 244, thereby facilitating the movement of the support rod 21 on the track rod 11.

[0043] Figure 3 yes Figure 1 A magnified view of region B in the middle, as shown below. Figure 1 and Figure 3 As shown, each end of the support rod 21 is provided with a set of clamping plates 22 and clamping drive members 23; the clamping plates 22 are hinged to the ends of the support rods 21, and the clamping plates 22 include a driving part and a clamping part. The clamping drive members 23 are located at the ends of the support rods 21, and the clamping drive members 23 can be drive cylinders (such as hydraulic cylinders or pneumatic cylinders). The telescopic rod of the drive cylinder is connected to the driving section of the clamping plate 22. Specifically, a sliding groove 221 is opened on the driving part of the clamping plate 22, and the telescopic rod of the drive cylinder can pass through the sliding groove 221. Two abutting ball heads 23 are provided on the telescopic rod. 1. The driving part of the clamping plate 22 is clamped between the two abutting ball heads 231. When the driving cylinder can remain stationary, the telescopic rod of the driving cylinder and the sliding groove 221 can slide relative to each other, thereby enabling the clamping plate 22 to rotate. This causes the clamping parts on the clamping plate 22, which are arranged opposite to each other at both ends of the support rod 21, to move closer or further apart. When the clamping parts on the clamping plate 22, which are arranged opposite to each other at both ends of the support rod 21, move closer together, the brick blank is clamped, and when the clamping parts on the clamping plate 22, which are arranged opposite to each other at both ends of the support rod 21, the brick blank is released.

[0044] Figure 4 yes Figure 1 Enlarged view of region C, as shown Figure 1 and Figure 4 As shown, the scissor lift adjustment unit 3 can be configured to include several scissor lifts 31, a telescopic adjuster 32 (such as a hydraulic cylinder or a pneumatic cylinder), and a rod end sliding seat 33. Two scissor lifts 31 are provided between each pair of adjacent support rods 21, and the middle of the two scissor lifts 31 are hinged together. Each support rod 21 is provided with a rod end fixing seat 211, and the rod end sliding seat 33 is sleeved on the support rod 21 and can move along the support rod 21. One end of each scissor lift 31 is hinged to the rod end fixing seat 211 on one of the two support rods 21. The other end of the fork 31 is hinged to the rod end sliding seat 33 on the other of the two support rods 21, and the two ends of the telescopic adjuster 32 are respectively connected to the rod end fixing seat 211 and the rod end sliding seat 33 on the same support rod 21. The telescopic adjuster 32 can drive the rod end sliding seat 33 to move closer to or away from the rod end fixing seat 211, so that when the rod end sliding seat 33 moves closer to the rod end fixing seat 211, the adjacent support rods 21 move away from each other, and when the rod end sliding seat 33 moves away from the rod end fixing seat 211, the adjacent support rods 21 move closer to each other.

[0045] The above-described structural design allows for adjustment of the spacing between adjacent support rods 21 by extending and retracting the telescopic adjuster 32. This results in a smaller spacing between adjacent support rods 21 when clamping brick blanks, facilitating the clamping of multiple closely arranged brick blanks. When the brick blanks are moved to the designated stacking area, the spacing between adjacent support rods 21 is increased, thereby enabling sparse stacking of brick blanks. This makes it easier for the stacked bricks to be thoroughly fired in the kiln and prevents bricks from sticking together.

[0046] Figure 5 yes Figure 1 A magnified view of region D, specifically, as shown below. Figure 4 and Figure 5 As shown, the rod end fixing seat 211 is fixedly connected to the support rod 21, and the rod end fixing seat 211 is provided with a fixing seat hinge shaft 2111. The end of the scissor bar 31 can be hinged to the fixing seat hinge shaft 2111. The rod end sliding seat 33 includes a first sliding flange plate 331, a second sliding flange plate 332, a sliding flange plate connecting bolt 333, and a sliding roller 334. The first sliding flange plate 331 is provided with a flange plate hinge shaft 3311. The end of the scissor bar 31 can be hinged to the flange plate hinge shaft 3311. In addition, the telescopic adjuster 32 can be connected to the rod end fixing seat 211 and the rod end sliding seat 33 by hinged to the fixing seat hinge shaft 2111 and the flange plate hinge shaft 3311, so that the position of the rod end sliding seat 33 can be adjusted, thereby realizing the adjustment of the scissor bar adjustment unit 3.

[0047] like Figure 5 As shown, taking the support rod 21 as a square tube as an example, both the first sliding flange plate 331 and the second sliding flange plate 332 can be set as rectangular plates. Matching flange connection holes are provided at the corners of both the first sliding flange plate 331 and the second sliding flange plate 332. The sliding flange plate connecting bolts 333 pass sequentially through the flange connection holes on the first sliding flange plate 331 and the second sliding flange plate 332 and are connected with nuts to achieve the connection between the first sliding flange plate 331 and the second sliding flange plate 332. A suitable space for accommodating the support is formed between the first sliding flange plate 331 and the second sliding flange plate 332. The receiving cavity of the rod 21 allows the rod end sliding seat 33 to be sleeved on the support rod 21, thereby enabling the connection between the support rod 21 and the scissor lift 31 and allowing the scissor lift 31 to move on the support rod 21 to achieve deformation adjustment of the scissor lift adjustment unit 3; the sliding roller 334 is rotatably connected to the side of the first sliding flange plate 331 facing the support rod 21, and the axial direction of the sliding roller 334 is perpendicular to the length direction of the support rod 21, so that there is rolling friction between the rod end sliding seat 33 and the support rod 21, thereby reducing the resistance of the scissor lift adjustment unit 3 during deformation adjustment.

[0048] Figure 6 This is a top view of the brick clamping assembly of this application (the brick clamping assembly has a symmetrical structure, and only the left side is shown in the diagram), as follows. Figure 6 As shown, the scissor bar 31 closer to the middle of the track bar 11 is longer, which makes the deformation of a pair of scissor bars 31 closer to the middle of the track bar 11 greater. This allows the spacing between the two support bars 21 closer to the middle of the track bar 11 to be larger when adjusting the spacing between adjacent support bars 21. This makes the gaps in the part of the stacked brick pile closer to the core larger, making the brick pile easier to burn through.

[0049] like Figure 6 As shown, when the scissor lift 31 is set to be longer the closer it is to the middle of the track rod 11, each first sliding flange plate 331 can be provided with two flange plate hinge shafts 3311. The line connecting the two flange plate hinge shafts 3311 is inclined in the direction from the middle of the track rod 11 to the middle of the track rod 11 away from the middle of the track rod 11, and in the direction from the middle of the support rod 21 away from the middle of the support rod 21. Each fixed seat is also provided with two fixed seat hinge shafts 2111, and the line connecting the two fixed seat hinge shafts 2111 is inclined in the direction from the middle of the track rod 11 to the middle of the track rod 11 away from the middle of the track rod 11, and in the direction from the middle of the support rod 21 away from the middle of the support rod 21.

[0050] Furthermore, two adjacent support rods 21 arranged sequentially in the direction extending from the middle of the track rod 11 to its end are designated as support rod A and support rod B. The two scissor rods 31 between the two support rods 21 are designated as scissor rod A and scissor rod B. The closer the support rod 21 is to the middle of the track rod 11, the larger the distance between the fixed seat on it and the end of the support rod 21 is, so that the line connecting the fixed seat hinge shaft 2111 on support rod A, which is away from the end of the support rod 21, and the fixed seat hinge shaft 2111 on support rod B, which is near the end of the support rod 21, can be parallel to the length direction of the track rod 11.

[0051] Based on the above structural configuration, one hinged end of scissor bar A can be hinged to the fixed seat hinge shaft 2111 on the support rod A near the end of the support rod 21, and the other hinged end can be hinged to the flange plate hinge shaft 3311 on the support rod B near the fixed seat. Similarly, one hinged end of scissor bar B can be hinged to the fixed seat hinge shaft 2111 on the support rod B away from the end of the support rod 21, and the other hinged end can be hinged to the flange plate hinge shaft 3311 on the support rod A away from the fixed seat. This connection method of scissor bars 31 makes it easier to set the deformation of each set of scissor bars 31, so that the deformation dimensions between adjacent sets of scissor bars 31 will not interfere with each other.

[0052] The second aspect of this application provides a sintered brick blank stacking machine, which includes a rotating base 5, a rotating unit 6, a brick blank clamping assembly as described above, and a robotic arm 4. The robotic arm 4 is mounted on the rotating base 5 and connected to the brick blank clamping assembly via the rotating unit 6. The rotating base 5 drives the robotic arm 4 to rotate vertically, the robotic arm 4 drives the rotating unit 6 to move horizontally and vertically, and the rotating unit 6 drives the brick blank clamping assembly to rotate vertically. Thus, the rotating base 5 and the robotic arm 4 can realize the transfer of brick blanks to a set stacking area. The robotic arm 4, rotating unit 6, and brick blank clamping assembly can achieve staggered and spaced stacking of brick blanks, making the stacked brick pile more solid and spaced, and making the brick pile easier to fire through. In addition, the rotating base 5 and the rotating unit 6 mentioned above are both based on existing technology, which will not be described in detail here.

[0053] like Figure 2As shown, the robotic arm 4 should be configured to include a first movable arm 41 and a second movable arm 42. One end of the first movable arm 41 is rotatably connected to the rotating seat 5, and the other end is rotatably connected to the second movable arm 42, so that the first movable arm 41 can be driven to rotate in the vertical direction via the rotating seat 5, and the second movable arm 42 can be driven to move in the horizontal and vertical directions via the first movable arm 41. The second movable arm 42 is also rotatably connected to the rotating unit 6, so that the rotating unit 6 can be driven to move in the horizontal and vertical directions via the second movable arm 42. During the rotation of the first movable arm 41 and the second movable arm 42, the brick blank clamping assembly is in a horizontal state, thereby enabling the stacking of brick blanks in an alternating manner.

[0054] Specifically, based on the above technical solution, the process of stacking brick blanks is as follows:

[0055] S1. Control the robotic arm 4 to lift the brick blank clamping assembly to a safe position, and use the telescopic adjuster 32 on the brick blank clamping assembly to retract the support rods 21 together, and use the clamping drive 23 to keep the clamping plates 22 on each support rod 21 in the open position.

[0056] S2. The rotating seat 5 drives the robotic arm 4 to rotate to a set angle, and the robotic arm 4 lowers the brick blank clamping assembly so that the brick blank to be clamped is between the relatively set clamping plates 22. This allows the relatively set clamping plates 22 to be controlled to move closer to each other to clamp the brick blank. After clamping, the robotic arm 4 is also controlled to lift the brick blank clamping assembly to a safe position.

[0057] S3. The rotating seat 5 drives the robotic arm 4 to rotate to the set angle, and the robotic arm 4 lowers the brick blank clamping assembly. At the same time as lowering, the support rod 21 is separated by the telescopic adjuster 32 on the brick blank clamping assembly so that the clamped brick blank is in the set stacking position. Then, the relatively set clamping plates 22 are controlled to move away from each other to release the brick blank and stack it in place.

[0058] S4. Repeat steps S1 and S2 in sequence. Then, the rotating seat 5 drives the robotic arm 4 to rotate to the set angle. After rotating the brick blank clamping assembly by 90° through the rotating unit 6, the robotic arm 4 lowers the brick blank clamping assembly so that the clamped brick blank is in the set stacking position. This allows the relatively set clamping plates 22 to move away from each other so that the brick blank is stacked in place, thus achieving staggered stacking.

[0059] S5. Control the robotic arm 4 to lift the brick blank clamping assembly to a safe position, and retract the support rod 21 by using the telescopic adjuster 32 on the brick blank clamping assembly. Use the clamping drive 23 to keep the clamping plates 22 on each support rod 21 in the open position. Also, use the rotating unit 6 to rotate the brick blank clamping assembly 90° back to its original position. Then repeat steps S2 and S3 in sequence.

[0060] S6. Alternately repeat steps S4 and S5 until the brick blanks are stacked.

[0061] The working principle of the brick blank clamping assembly and the sintered brick blank stacking machine of this application is as follows:

[0062] The support rod 21 is equipped with clamping plates 22 and clamping drive components 23 at both ends, so that each support rod 21 can clamp a row of brick blanks. Furthermore, the gap between the two support rods 21 can be adjusted by the scissor adjustment unit 3, thereby adjusting the spacing between each row of brick blanks to ensure that there is a certain gap in the stacked bricks, so that heat can enter the middle of the brick stack, which is conducive to the thorough firing of the bricks and can reduce the sticking of the fired bricks.

[0063] The rotating seat 5 and the robotic arm 4 enable the transfer of brick blanks to a designated stacking area. The rotating unit 6 of the robotic arm 4 and the brick blank clamping assembly enable the brick blanks to be stacked in an alternating and spaced manner, making the stacked bricks more solid and spaced, thus making the bricks easier to fire thoroughly.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
