Description

Technical Field

[0001] The invention relates to the technical field of brick stacking, in particular to an automatic brick stacking robot for a brick making machine. Background Art

[0002] A brick-making machine is a piece of machinery used to produce bricks, widely used in the building materials industry. Common types include press-forming machines, which use high pressure to compress raw materials into shape, and vibratory-forming machines, which use vibration to compact the raw materials within a mold before releasing them from the mold. Brick-making machines are often equipped with an automated stacking system, consisting of a conveyor belt that transports the finished bricks from the machine's output to the stacking location, a robot that grabs and places the bricks, and a stacking platform for stacking the bricks. This stacking system is crucial for ensuring quality and improving overall work efficiency.

[0003] However, the following problems still exist in the process of stacking bricks: (1) When the existing robot grabs multiple bricks at one time, only the side of the brick close to the grabbing side is subjected to the grabbing force, and the multiple bricks are often squeezed and fitted together. The bricks in this grabbing state are prone to shaking or falling off due to unbalanced force and lack of bottom support, and the bricks squeezed and fitted together will be damaged to a certain extent due to friction or collision, thereby affecting the quality of the bricks.

[0004] (2) The method of directly grabbing bricks and placing them on the top of the stacking platform makes it difficult to ensure that the bricks are accurately and neatly placed at the designated stacking points. There is a certain position deviation between the stacked bricks in the horizontal and vertical planes, which may cause the stacked bricks to tilt or collapse. The neatness and stability of the brick stacking need to be improved.

[0005] Therefore, in order to solve the problems existing in the brick stacking process, the present invention provides an automatic brick stacking robot for a brick making machine. Summary of the Invention

[0018] 3. The guide assembly used in the present invention can guide and position the movement of the grabbing mechanism and the placement of bricks, which can not only ensure that the bricks are accurately, stably and neatly stacked at the designated points on the stacking platform, thereby increasing the stacking accuracy, but also reduce the stacking deviation caused by external factors by providing a stable guide path, so that the bricks can be placed smoothly in place, ensuring that bricks at the same point but different heights are aligned with each other, thereby improving the neatness and stability of the brick stacking.

DETAILED DESCRIPTION

[0031] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

A conveying device 2 for conveying bricks is provided at the rear side of the robot 1. A stacking platform 3 for stacking bricks is provided on the left side of the robot 1. The working end of the robot 1 has the function of circumferential rotation. The conveying device 2 is a prior art. The conveying device 2 can intermittently convey bricks from right to left to the gripping station through the conveying surface, and four bricks arranged in two rows and two columns are conveyed as a unit, and the long side of the brick is perpendicular to the movement direction of the conveying surface. Before the bricks are conveyed to the gripping station, the conveying device 2 can be provided with an existing position correction device or manually perform position fine-tuning operations to make the brick unit basically located in the middle of the conveying surface, and the bricks in the same unit are kept in an orderly arranged state, with a certain gap between adjacent bricks. The subsequent gripping mechanism 11 can grab the brick units one by one and place them on the upper end of the stacking platform 3.

[0033] See also Figure 1 、 Figure 3 、 Figure 4 and Figure 6 The grabbing mechanism 11 includes a connecting frame 12 installed at the lower end of the working end of the manipulator 1, and an inverted frame 13 is installed at the lower end of the connecting frame 12. A grabbing assembly is provided below the horizontal section of the inverted frame 13. The grabbing assembly includes a rectangular plate 131. A cross partition 132 is installed in the middle of the lower end of the rectangular plate 131. Elastic rubber pads are provided on the front and rear sides of the transverse section and the left and right sides of the longitudinal section of the cross partition 132. L-shaped splints 133 are provided at the four corners of the lower end surface of the rectangular plate 131. The height of the L-shaped splint 133 is less than the thickness of the brick. The upper side of the rectangular plate 131 is connected to a push plate through a driving member. 137, and the rectangular plate 131, the pushing plate 137 and the driving member together constitute a four-sided pyramid stable structure, the driving member includes a square plate installed on the upper end of the L-shaped splint 133, and the upper end of the square plate is installed with a sliding column 134 that is slidably connected to the rectangular plate 131, and the sliding column 134 is distributed on the diagonal of the rectangular plate 131, and the intersection of the two diagonals of the rectangular plate 131 is concentric with the cross partition 132. The upper end of the sliding column 134 passes through the rectangular plate 131 and is installed with a moving plate 135, and the upper end of the moving plate 135 is hinged with a connecting plate 136, and the other ends of all connecting plates 136 are hinged to the pushing plate 137.

[0034] See also Figure 1 、 Figure 3 and Figure 4 The inverted frame 13 is provided with a moving assembly for controlling the upward and downward movement of the push plate 137. The moving assembly includes a hydraulic rod 138 installed on the horizontal section of the inverted frame 13. The lower end of the pushing end of the hydraulic rod 138 is connected to the upper end of the pushing plate 137. The upper end of the rectangular plate 131 is installed with an inverted U-shaped plate 139 that slides up and down with the horizontal section and the pushing section of the hydraulic rod 138. The inverted U-shaped plate 139 extends in the front and rear directions. The two vertical sections of the inverted U-shaped plate 139 correspond to the two connecting plates 1 36, support plates 141 are installed on the front and rear sides of the horizontal section of the inverted U-shaped plate 139, which are slidably connected to the corresponding vertical sections of the inverted frame 13. Two support rods 142 that slide up and down and penetrate the horizontal section of the inverted frame 13 are installed on the upper end of the horizontal section of the inverted U-shaped plate 139. The pushing section of the hydraulic rod 138 is located between the two support rods 142. A support spring sleeved on the outside of the corresponding support rod 142 is connected between the lower end of the horizontal section of the inverted frame 13 and the upper end of the horizontal section of the inverted U-shaped plate 139.

[0035] During specific operation: after a unit of bricks is conveyed to the location of the grabbing station, the conveying equipment 2 suspends conveying. At the same time, the working end of the manipulator 1 can drive the grabbing mechanism 11 to move to the location of the bricks. During this process, the connecting frame 12 can drive the inverted frame 13 and the grabbing assembly to move downward perpendicular to the conveying surface, and the rectangular plate 131 drives the cross partition 132 and the L-shaped splint 133 to move downward synchronously until the cross partition 132 passes through the gap between the four bricks and collides with the conveying surface. The rectangular plate 131 is pressed on the upper end face of the brick. At this time, the L-shaped splint 133 is located away from the bricks. Since the positions of the four bricks have been basically corrected in advance and there are gaps between adjacent bricks, the cross partition 132 can smoothly separate the four bricks arranged in two rows and two columns, and make the four bricks respectively located in the four small squares formed by the cross partition 132, ensuring that each brick is in a relatively independent space.

[0036] Then, the hydraulic rod 138 (the hydraulic rod 138 is connected to the existing hydraulic pump provided on the manipulator 1) can pull the push plate 137 to move upward, and the push plate 137 drives the connecting plate 136 connected thereto to move upward synchronously, and the corresponding moving plate 135 and the sliding column 134 move synchronously along the diagonal of the rectangular plate 131 toward the center of the rectangular plate 131 with the connecting plate 136. Since the sliding columns 134 are distributed on the diagonal of the rectangular plate 131, the intersection of the two diagonals of the rectangular plate 131 is concentric with the cross partition 132, so the L-shaped splint 133 can gradually approach the brick while moving with the corresponding sliding column 134 until the L-shaped splint 133 is pressed against the right-angle end of the corresponding brick, and the brick with a certain position offset is moved by the corresponding The pressing force of the L-shaped splint 133 can simultaneously press against the elastic rubber pads on the corresponding transverse and longitudinal sections of the cross partition 132. The elastic rubber pads can not only provide a certain elastic moving distance for the bricks, but also increase the friction between the cross partition 132 and the bricks, which is beneficial to improving the clamping force of the bricks and providing elastic buffering protection for the bricks. Under the action of the four L-shaped splints 133 and the cross partition 132, the four bricks are synchronously pressed between the cross partition 132 and the corresponding L-shaped splint 133, and the four sides of each brick can be subjected to uniform and balanced pressing pressure, which not only helps to maintain the stability of a single brick and the brick unit as a whole during the grasping process, but also can prevent damage caused by friction or collision between bricks.

[0037] See also Figure 4 、 Figure 5 and Figure 6The position of the lower end of the pushing plate 137 corresponding to the connecting plate 136 is installed with an elastic retractable plate 143 fixedly connected to the upper end surface of the rectangular plate 131. The connecting plate 136 is hinged on one side of the center of the rectangular plate 131 with a connecting retractable plate 144 hinged to the fixed section of the corresponding elastic retractable plate 143. The telescopic section of the connecting retractable plate 144 is provided with evenly arranged mounting holes 145, and the corresponding mounting holes 145 are inserted with limit blocks 146 for limiting the fixed section. The L-shaped splint 133 is installed with connecting plates 147 and plugging plates 148 on different sides. The two adjacent L-shaped splints 133 are connected by slidingly fitting connecting plates 147 and plugging plates 148, and the connecting plates 147 slide in conjunction with the opening grooves on the plugging plates 148.

[0038] In the process of pushing the plate 137 upward, the elastic telescopic plate 143 is synchronously extended, and the angle between the connecting plate 136 and the elastic telescopic plate 143 changes synchronously. At this time, the connecting telescopic plate 144 can shrink and rotate synchronously with the change of the angle between the two. When the connecting plate 136 rotates to a certain angle, the fixed section of the connecting telescopic plate 144 just conflicts with the limit block 146 set on the telescopic section. The limit block 146 can control the shrinkage distance of the connecting telescopic plate 144, and then control the rotation angle of the connecting plate 136. It is also a control of the upward movement height of the pushing plate 137 and the grasping force exerted on the brick, effectively preventing the brick from being damaged due to excessive grasping force or loosening due to insufficient grasping force. When it is necessary to adjust the grasping force exerted on the brick, the limit block 146 can be inserted into the appropriate mounting hole 145 to complete the adjustment of the limit position. The pushing plate 137 and the four connecting plates 136 form a stable quadrangular pyramid structure, and the connecting plate 136 and the elastic telescopic plate 143, the connecting telescopic plate 144, and the rectangular plate 131 form multiple stable triangular structures, thereby enhancing the structural stability and reliability of the grabbing assembly.

[0039] When the L-shaped clamps 133 are pressed against the bricks, the total length of the sliding connecting plates 147 and the inserting plates 148 is reduced, and the four L-shaped clamps 133 are connected to each other through the corresponding connecting plates 147 and the inserting plates 148, thereby improving the connection and relative stability between the L-shaped clamps 133, thereby enhancing the stability of the clamping force on the bricks.

[0040] See also Figure 3 、 Figure 4 、 Figure 7 and Figure 8The lower ends of the two vertical sections of the inverted frame 13 are both provided with a bottom support assembly for supporting bricks, and the bottom support assembly includes a Z-shaped support plate 151. The distance between the upper and lower horizontal sections of the Z-shaped support plate 151 is greater than the thickness of the brick. The vertical section of the inverted frame 13 is provided with a control member for controlling the corresponding Z-shaped support plate 151 in the front and rear directions. The control member includes a sliding plate 152 that is slidably connected to the corresponding vertical section of the inverted frame 13. The lower end of the vertical section corresponding to the inverted frame 13 is installed with a bottom plate after passing through the sliding plate 152. The bottom plate can limit the lower end of the sliding plate 152. The upper horizontal section of the Z-shaped support plate 151 slides on the sliding plate 152 in the front and rear direction. The upper end of the upper horizontal section of the Z-shaped support plate 151 is away from the rectangular plate 131 and is provided with a strip plate 153. The sliding plate 152 is provided with a sliding connection with the strip plate 153 The mounting groove extends along the front-to-back direction, and a control spring 154 is connected between the strip plate 153 and the side wall of the mounting groove. A control plate 155 slidably connected to the sliding plate 152 is installed on the upper end of the strip plate 153, and the control plate 155 slides along the front-to-back direction. Two vertical slot plates 156 along the left and right directions are installed on the upper end of the control plate 155. A side groove 157 is provided on the side of the vertical section corresponding to the inverted frame 13 close to the rectangular plate 131. The upper end of the bottom wall of the side groove 157 is hinged to a multi-stage elastic telescopic column 158 through a torsion spring shaft. The telescopic end of the multi-stage elastic telescopic column 158 is hinged with a pin shaft that is slidably connected up and down between the corresponding two vertical slot plates 156. The elastic coefficient of the multi-stage elastic telescopic column 158 is greater than the elastic coefficient of the control spring 154, and the elastic coefficient of the torsion spring shaft is greater than the elastic coefficient of the multi-stage elastic telescopic column 158.

[0041] See also Figure 3 、 Figure 7 、 Figure 8 and Figure 9 , a connecting piece is provided between the Z-shaped support plate 151 and the grab assembly, the connecting piece includes L-shaped push rods 159 installed on both sides of the left and right sides of the vertical section of the Z-shaped support plate 151, and a push block 161 is installed on the side away from the two L-shaped clamping plates 133 corresponding to the Z-shaped support plate 151, which cooperates with the corresponding L-shaped push rod 159 longitudinal section. The upper end of the lower horizontal section of the Z-shaped support plate 151 is rotatably installed with rollers 162 evenly arranged along the front and rear directions. Two sliding grooves symmetrically distributed about the rollers 162 are opened on the lower horizontal section of the Z-shaped support plate 151. The sliding groove extends along the front and rear directions and is connected to a vertical rod 163 for front and rear sliding connection therein, and a lifting plate 164 that slides with the lower end of the Z-shaped support plate 151 is jointly installed between the lower ends of the two vertical rods 163. The lifting plate 164 slides along the front and rear directions, and the upper end of the vertical rod 163 is installed with a connecting telescopic rod 165 with a fixed end fixedly connected to the support plate 141.

[0042] After the grabbing assembly grabs the brick, the hydraulic rod 138 can continue to pull the push plate 137 to move upward. Since the upward movement height of the push plate 137 is limited at this time, and the connecting frame 12 and the inverted frame 13 are always fixed at the lower end of the working end of the manipulator 1, the push plate 137 can drive the rectangular plate 131 and the bricks in the clamped state to move upward through the connecting plate 136 and the moving plate 135. The rectangular plate 131 drives the front and rear support plates 141 along the vertical sections corresponding to the inverted frame 13 through the inverted U-shaped plate 139. The support plate 141 can guide and support the upward movement of the inverted U-shaped plate 139, the grabbing assembly and the bricks. The inverted U-shaped plate 139 drives the front and rear support rods 142 to move upward synchronously and compress the support spring.

[0043] In the initial state, the longitudinal sections of the L-shaped supporting rods 159 on the left and right sides of the Z-shaped supporting plate 151 are in conflict with the corresponding supporting blocks 161 on the L-shaped clamping plate 133. The upper horizontal section of the Z-shaped supporting plate 151 is located inside the sliding plate 152 through the tension control spring 154 of the strip plate 153. At this time, the multi-stage elastic telescopic column 158 is in a contracted state. In the process of the L-shaped clamping plate 133 moving to clamp the bricks, the Z-shaped supporting plate 151 is moved under the rebound force of the control spring 154. The L-shaped splint 133 moves synchronously to the brick, the strip plate 153, the control plate 155 and the vertical slot plate 156 move synchronously with the Z-shaped support plate 151, the multi-stage elastic telescopic column 158 extends synchronously, and the longitudinal section of the L-shaped push rod 159 always conflicts with the corresponding push block 161. When the grabbing assembly and the brick in the clamping state move upward, the push block 161 moves upward synchronously with the corresponding L-shaped splint 133 and gradually separates from the longitudinal section of the L-shaped push rod 159. At this time, the Z-shaped support plate 151 is in a state of being moved upward. 51 can continue to move along the sliding plate 152 toward the direction of the brick under the action of the rebound force of the control spring 154, and the horizontal section below the Z-shaped support plate 151 gradually moves to between the lower ends of the corresponding left and right bricks. At this time, the control spring 154 and the multi-stage elastic telescopic column 158 are both in a naturally expanded state, and the lower horizontal section of the Z-shaped support plate 151 can rotate and contact with the lower end surface of the brick through the roller 162 to reduce the friction between the brick and the Z-shaped support plate 151, ensuring that the Z-shaped support plate 151 moves smoothly to the lower end of the brick. The Z-shaped support plate 151 can provide bottom support for the brick to prevent the brick from falling off during the subsequent grabbing and stacking process, further improving the stability of the brick grabbing process. It should be noted that since the elastic coefficient of the multi-stage elastic telescopic column 158 is greater than the elastic coefficient of the control spring 154, the Z-shaped support plate 151 can move smoothly under the dual elastic force of the control spring 154 and the multi-stage elastic telescopic column 158.

[0044] In the process of the inverted U-shaped plate 139 driving the support plate 141 to move upward, the connecting telescopic rod 165, which was originally in a contracted state, is synchronously extended to the maximum extension state. However, during this process, the connecting telescopic rod 165 will not affect the state of the Z-shaped support plate 151 through the corresponding vertical rod 163 and the lifting plate 164. The horizontal section below the Z-shaped support plate 151 can be moved to the lower end of the brick through the sliding groove along the corresponding vertical rod 163 and the lifting plate 164. The lifting plate 164 can provide support for the horizontal section below the Z-shaped support plate 151, ensuring that the Z-shaped support plate 151 is in a stable and balanced state, which helps to improve the stability of the Z-shaped support plate 151 when supporting bricks. Before placing the bricks on the stacking platform 3, the bottom support of the bricks by the Z-shaped support plate 151 can be released first. During this process, the hydraulic rod 138 can continue to pull the grabbing assembly, bricks and inverted U-shaped plate 139 upward. At this time, the connecting telescopic rod 165 in the maximum extension state can pull the lifting plate 164 upward through the vertical rod 163. The lifting plate 164 pulls the corresponding Z-shaped support plate 151, the sliding plate 152 and the bottom support assembly (except the multi-stage elastic telescopic column 158) along the vertical section corresponding to the inverted U-shaped frame 13 upward. During the upward movement, the sliding plate 152 can squeeze the fixed end of the corresponding multi-stage elastic telescopic column 158, so that the multi-stage elastic The multi-stage elastic telescopic column 158 rotates around the hinge point between it and the corresponding side groove 157 in the direction of the side groove 157. The telescopic end of the multi-stage elastic telescopic column 158 can drive the control plate 155 to move along the sliding plate 152 toward the direction of the corresponding vertical section of the inverted frame 13 through the cooperation between the pin shaft and the corresponding left and right vertical groove plates 156. The control plate 155 drives the horizontal section above the Z-shaped support plate 151 to move synchronously along the sliding plate 152 through the strip plate 153, and the control spring 154 extends synchronously therewith. The horizontal section on the lower side of the Z-shaped support plate 151 moves synchronously therewith and gradually separates from the lower end surface of the brick, and the multi-stage elastic telescopic column 158 gradually rotates to an inclined state.

[0045] See also Figure 7 、 Figure 8 and Figure 9 , the front and rear sides of the rectangular plate 131 are provided with avoidance grooves for avoiding the Z-shaped support plate 151, and a card plate 166 is installed on the side close to the lower horizontal section of the two Z-shaped support plates 151. The upper end surface of the card plate 166 is located below the upper end surface of the lower horizontal section of the Z-shaped support plate 151, and a vertical plate 167 is provided in the avoidance groove. A cross bar 168 is installed on the upper end of the vertical plate 167, and fixed columns 169 are installed on the left and right sides of the cross bar 168 for sliding up and down. The fixed columns 169 are installed at the upper end of the rectangular plate 131, and the avoidance groove is located between the two fixed columns 169 corresponding to the same cross bar 168. A telescopic spring sleeved on the outside of the fixed column 169 is connected between the cross bar 168 and the rectangular plate 131.

[0046] In the initial state, the telescopic spring is in the maximum stretched state, and the lower end of the vertical plate 167 is pressed against the upper end of the horizontal section under the Z-shaped support plate 151. In the process of the horizontal section under the Z-shaped support plate 151 moving to the lower end of the brick, although the rectangular plate 131 drives the fixed column 169, the telescopic spring, the cross bar 168 and the vertical plate 167 to move upward synchronously, the cross bar 168 at this time can still push the vertical plate 167 to press against the upper end of the horizontal section under the Z-shaped support plate 151 under the action of the telescopic spring, and the vertical plate 167 and the roller 168 are in a state of tension. 2 rolling contact without affecting the movement of the Z-shaped support plate 151. When the lower horizontal section of the Z-shaped support plate 151 moves away from the brick, the clamping plate 166 moves synchronously with the corresponding Z-shaped support plate 151. When the clamping plate 166 moves below the vertical plate 167, the vertical plate 167 is separated from the lower horizontal section of the Z-shaped support plate 151 and moves downward under the rebound force of the telescopic spring until it presses against the upper end of the clamping plate 166. The cooperation between the vertical plate 167 and the clamping plate 166 can limit the reset Z-shaped support plate 151.

[0047] When the subsequent grabbing assembly releases the clamping of the brick, the hydraulic rod 138 can push the pushing plate 137 to move downward. At this time, the brick has not yet contacted the upper end surface of the stacking platform 3. Under the action of the support rod 142 and the support spring, the grabbing assembly and the gravity of the brick itself, the inverted U-shaped plate 139, the side plate and the grabbing assembly move downward synchronously, but the grabbing assembly at this time still keeps clamping the brick, and the connecting telescopic rod 165 shrinks synchronously with the downward movement of the side plate. In addition, the vertical plate 167 pushes the card plate 166 to make the Z-shaped support plate 151, the sliding plate 152 and the bottom support assembly as a whole move downward and reset synchronously with the grabbing assembly. The multi-stage elastic telescopic column 158 rotates and resets synchronously under the action of the torsion spring shaft, the control plate 155 and the vertical slot plate 156. In addition, the rotation and reset of the multi-stage elastic telescopic column 158 also helps to reset the sliding plate 152 downward. Since the vertical plate 167 keeps limiting the card plate 166 and the Z-shaped support plate 151, the multi-stage elastic telescopic column 158 shrinks to the initial state synchronously. After the grabbing assembly and the bottom support assembly are reset, the brick can be placed just on the upper end of the stacking platform 3. At this time, the hydraulic rod 138 can continue to push the pushing plate 137 downward, and the grabbing assembly can release the clamping of the brick in the opposite way to place the brick on the upper end of the stacking platform 3. At the same time, the front and rear cross bars 168 can be pulled upward synchronously with the help of external force. The vertical plate 167 moves upward synchronously with the cross bar 168 and gradually moves away from the corresponding card plate 166 and the lower horizontal section of the Z-shaped support plate 151. At this time, the Z-shaped support plate 151 can drive the L-shaped push rod 159 to contact the pressed block 161 again under the action of the control spring 154 and the multi-stage telescopic column. When the push plate 137 moves downward for the first time, the bottom support assembly and the grab assembly move downward as a whole, and the bottom support assembly is reset. When the push plate 137 moves downward for the second time, only the grab assembly moves downward, and the bottom support assembly remains stationary. After moving downward twice, the connecting telescopic rod 165 is in a fully retracted state. When the push plate 137 moves downward for the third time, the grab assembly can release the clamping of the brick.

[0048] See also Figure 1 and Figure 2 The upper end of the stacking platform 3 is provided with a positioning component for guiding and positioning the grabbing mechanism 11. The positioning component includes a left side plate 31 and a front side plate 32 respectively provided on the left and front sides of the stacking platform 3. A plurality of positioning rods 33 are provided on the upper end of the left side plate 31 and the upper end of the front side plate 32. The positioning rods 33 corresponding to the left side plate 31 are evenly arranged along the front and rear directions, and the positioning rods 33 corresponding to the front side plate 32 are evenly arranged along the left and right directions. A guide groove 34 is provided on the positioning rod 33. The middle part of the left end of the rectangular plate 131 and the middle part of the rear end of the vertical section on the rear side of the inverted frame 13 are both installed with a guide rod 35 that slides up and down with the corresponding guide groove 34. The length of the guide rod 35 meets the requirements of the grabbing mechanism 11. In order to move to any position of the stacking platform 3, two left insertion rods 36 distributed along the front-to-back direction are installed on the left side of the stacking platform 3, and the left insertion rods 36 slide along the left-to-right direction on the left side plate 31, and two front insertion rods 37 distributed along the left-to-right direction are installed on the front side of the stacking platform 3, and the front insertion rods 37 slide along the front-to-back direction on the front side plate 32. Rectangular holes 38 are provided at the upper end of the left side plate 31 and the upper end of the front side plate 32. The rectangular holes 38 of the left side plate 31 are evenly arranged along the front-to-back direction, and the corresponding rectangular holes 38 of the front side plate 32 are evenly arranged along the left-to-right direction. The number of rectangular holes 38 is more than the number of corresponding positioning rods 33, and the lower ends of the positioning rods 33 are plugged into the corresponding rectangular holes 38.

[0049] After the grabbing assembly completes grabbing of the brick, the manipulator 1 can drive the grabbing mechanism 11 and the brick to rotate as a whole to the top of the stacking platform 3 through the working end, and make the long side of the brick parallel to the front side plate 32, and the guide rod 35 at the middle of the left end of the rectangular plate 131 and the middle of the rear end of the vertical section of the rear side of the inverted profile 13 will move synchronously accordingly, with the leftmost side of the stacking platform 3 as the first column and the frontmost side as the first row, which is the first stacking point. When the grabbing mechanism 11 and the brick move to the first stacking point, the manipulator 1 can be used to adjust the guide rod 35 on the left side of the rectangular plate 131 to be directly above the leftmost positioning rod 33 on the front side plate 32, and adjust the guide rod 35 on the rear side of the inverted profile 13 to be directly above the frontmost positioning rod 33 on the left side plate 31, and The alignment between 5 and the positioning rod 33 can ensure that the grasping mechanism 11 and the bricks move to the top of the first stacking point. When the manipulator 1 controls the grasping mechanism 11 and the bricks to move down to the upper end of the stacking platform 3, the guide rod 35 can move downward along the guide groove 34 provided on the corresponding positioning rod 33. By utilizing the cooperation between the positioning rod 33, the guide groove 34 and the guide rod 35, the grasping mechanism 11 and the bricks can be limited in the front and back directions and the left and right directions, and can also be guided and supported for their downward movement, ensuring that the grasping mechanism 11 can accurately and stably place the bricks at the first stacking point, thereby neatly stacking the bricks at the upper end of the stacking platform 3. By analogy, the bricks can be neatly placed unit by unit at different points on the upper end of the stacking platform 3 in the subsequent process according to the same positioning method. It should be noted that the left side plate 31 is wider, which reserves space for the vertical section of the inverted frame 13, the sliding plate 152 and the Z-shaped support plate 151 when placing bricks, thereby minimizing the impact of the grabbing mechanism 11 on the distance between different brick units, thereby ensuring that different brick units are arranged in close proximity.

[0050] Since the positioning rods 33 are plugged into the corresponding rectangular holes 38, the positioning rods 33 can be flexibly removed from the corresponding front side panels 32 and left side panels 31. When the number of columns or rows of bricks to be stacked changes, the number of corresponding positioning rods 33 can be flexibly increased or decreased to meet the stacking requirements.
