In this embodiment, each row includes four guide bushes 13 , and the four guide bushes 13 in each row are evenly distributed. The main frame 1 is equipped with a block merging mechanism 2 for centralized merging of four concrete blocks and a grabbing mechanism 3 for grabbing and transporting the four merged blocks as a whole.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, Figure 5 and Figure 6, the block merging mechanism 2 includes two lifting cylinders 21 vertically fixed on the top of the main beam 12 through bolts. The two lifting cylinders 21 A lifting frame 22 with a square frame structure is fixed by bolts between the output rods. A contact pressure component 23 is installed in each guide bush 13 with a vertical sliding fit. All the contact pressure components 23 are fixed on the lifting frame 22 for common use. The blocks are pressed to form a pallet, and two merging plywood assemblies 24 are fixed on the lifting frame 22. The two merging plywood assemblies 24 are arranged opposite each other in mirror images in the distribution direction of the single row guide bushes 13. The contact assembly 23 includes a sliding rod 231 that is vertically slidably installed from the bottom end of the guide sleeve 13. The guide sleeve 13 is provided with a vertically extending travel hole 131. The sliding rod 231 is welded with a sliding rod 231 that passes through the travel hole 131 and is connected to the lifting frame 22. The welded connecting block 2311; the bottom end of the sliding rod 231 is fixed with an elastic contact end for elastic telescopic compression contact. The elastic contact end includes a telescopic sleeve 232 welded to the bottom end of the sliding rod 231. A telescopic rod 233 is installed in a sliding fit at the bottom of the telescopic rod 232. A contact flat plate 234 is welded horizontally to the bottom end of the telescopic rod 233. A pressure plate 234 is welded to the upper end of the telescopic rod 233. The two ends of the spring 235 and the compression spring 235 are respectively welded to the bottom end of the telescopic sleeve 232 and the upper end of the contact pressure plate 234. The merging splint assembly 24 includes two horizontal guide posts 241 welded on the lifting frame 22. The horizontal guide posts 241 are arranged axially parallel to the distribution direction of the single-row guide sleeves 13; The splint 242 has guide plates 243 symmetrically welded on both sides of the main beam 12 in the direction perpendicular to the horizontal guide column 241. The merge splint 242 is located between the two guide plates 243. The guide plate 243 is provided with an inclined guide hole 2431. The hole 2431 is inclined from top to bottom toward the other side of the merging splint assembly 24 . The two sides of the merging splint 242 are horizontally welded with corresponding driven pins 2421 inserted into the oblique guide holes 2431 on the same side. When the contact pressure component 23 descends with the lifting frame 22, the two merging splints 242 descend synchronously and move closer to each other synchronously. In this embodiment, there are two rows of eight contact pressure components 23 distributed in total, and the eight contact pressure components 23 are arranged corresponding to the eight hollow holes of the four hollow blocks in Figure 8 .

After the blocks on the forming pallet are dried, cured and finalized, the formed blocks can be transported and stacked in batches; when the manipulator is used to grab and transport the blocks on the forming pallet, the adhesive must first be The blocks combined on the forming pallet are separated from the forming pallet, and the four blocks are brought together and merged; the above actions can be completed by the block merging mechanism 2. Specifically, the manipulator is moved to the position to be grasped and transported above the four blocks, and then start the two lifting cylinders 21 synchronously to drive the lifting frame 22 down, thereby synchronously driving all the contact pressure components 23 to slide along their respective guide bushes 13 through the lifting frame 22. As they slide downward, the contact pressure components 23 slide down. The pressing plate 234 will extend into the corresponding hollow hole of the corresponding building block. As it continues to descend, the pressing plate 234 will be pressed against the molding support plate under the elastic force of the compression spring 235. When the touching component 23 follows the lifting frame 22 is lowered, under the guidance of the two inclined guide holes 2431, the two merging splints 242 are lowered synchronously on the one hand, and move closer to each other on the other hand, thereby pushing the four merging splints 242 during the movement of the two merging splints 242. The blocks are integrated together. During the merging process, the pressing plate 234 is in a compressed state against the forming support plate, so that the blocks and the forming support plate are separated from each other. Therefore, the block merging mechanism 2 can simultaneously complete the detachment between the blocks and the forming pallet during the process of merging and gathering the blocks, thereby avoiding the trouble of manually detaching the forming pallet and manually merging the blocks. , which also facilitates subsequent block grabbing.

As shown in Figures 1, 2, 3, 4 and 7, the grabbing mechanism 3 includes a grabbing assembly 34 correspondingly assembled at each guide sleeve 13, and the grabbing assembly is arranged at two rows of guide sleeves 13. 34 are distributed in the same state, and the four grabbing assemblies 34 in a single column are arranged in equal parts and opposite to each other in the column. The specific distribution state can be shown in Figure 2 and Figure 3; the bottom end of the main beam 12 is welded in a hanging shape through two connecting plates. There is a horizontal slide rail 32, and the sliding guide direction of the horizontal slide rail 32 is set along the distribution direction of the single row guide sleeve 13; the top of the main beam 12 is vertically fixed with an execution cylinder 31 through bolts, and a lifting beam 33 is provided above the horizontal slide rail 32. The top of the lifting beam 33 is fixed on the output end of the actuating cylinder 31. Two vertical guide posts 331 are vertically welded to the top of the lifting beam 33. The two vertical guide posts 331 are distributed on both sides of the actuating cylinder 31 and are slidably installed on the main On the cross beam 12; the grab assembly 34 includes a slide block 341 slidably installed on the horizontal slide rail 32. A connecting rod 342 is hinged between the upper end of the slide block 341 and the lifting beam 33. There is a No. 1 guide rod welded horizontally on the side wall of the slide block 341. 343. Two No. 2 guide rods 346 are welded horizontally on the side wall of the guide sleeve 13 at the corresponding position. The axial direction of the No. 1 guide rod 343 and the axial direction of the No. 2 guide rod 346 are both arranged along the sliding direction of the slider 341. The No. 1 guide rod 343 and the No. 2 guide rod 346 are slidably mounted with a grabbing splint 344. The grabbing splint 344 includes a sliding portion 3441 and a clamping portion 3442 that are integrally formed from top to bottom. The sliding portion 3441 is slidably mounted on the No. 1 guide rod 343 and the No. 1 guide rod 343. The No. 2 guide rod 346 and the No. 1 guide rod 343 are provided with a clamping spring 345. Both ends of the clamping spring 345 are welded to the slider 341 and the sliding part 3441 respectively; the gripping splint 344 is compared with the guide sleeve at the corresponding position. 13 is closer to the center position of the opposite arrangement in the guide bushes 13 in the same row. The corresponding positional relationship between the grabbing splint 344 and the guide bushing 13 at the corresponding position can be seen in Figure 2; in the present invention, in the two rows of grabbing assemblies 34 The two grabbing assemblies 34 at opposite positions form a combination that can grab a single double-hole hollow block as shown in Figure 8. They are divided into four groups in total, corresponding to grabbing four blocks. When grabbing, the gripping splint 344 In order to facilitate the extension into the hollow hole at the corresponding position in the corresponding block, the bottom end of the clamping part 3442 is provided with a bent section biased towards the slide block 341. In addition, in order to improve the connection between the clamping part 3442 and the hollow block. Due to the contact friction of the inner wall of the hollow hole, the side wall surface of the clamping part 3442 used for clamping is roughened. When a plurality of merged building blocks are grasped as a whole, the grasping assemblies 34 arranged oppositely in the two columns move closer to each other to complete the grasping action.

After completing the merging operation of the blocks, start the lifting cylinder 21 again and drive the lifting frame 22 to rise, so that the distance between the two merging splints 242 is opened again, and the contact assembly 23 is raised to the initial highest position. Then, the four blocks can be grabbed as a whole by the grabbing mechanism 3. Specifically, the moving device connected with the robot arm drives the robot arm to continue to descend, so that each grabbing splint 344 extends into the hollow hole at the corresponding position. Under the elastic force of the clamping spring 345, the clamping part 3442 is in a close state with the inner wall of the hollow hole. Subsequently, the lifting beam 33 is driven to rise through the execution cylinder 31, thereby pulling the slider 341 to slide horizontally through the connecting rod 342. The sliding of the rail 32, as shown in Figure 2, will cause the two sets of grabbing splints 344 on the left to move to the right, while the two sets of grabbing splints 344 on the right will move to the left, and the clamping spring 345 will be further compressed. When the four building blocks are kept in a merged state, the grabbing and clamping force of the four sets of grabbing assemblies 34 on the four building blocks is concentrated toward the middle, and the side clamp grabbing is completed; through the grabbing mechanism 3 provided by the present invention, When grasping, grasping contact can be made with each block, so the stability and reliability of grasping are higher.

A kind of concrete block production and handling robot is mainly used for overall grabbing and handling of a group of solidified blocks. It can first merge and gather multiple blocks through the set block merging mechanism 2, and complete it simultaneously. The automatic detachment between the blocks and the forming pallet avoids the trouble of manually detaching the forming pallet and manually merging the blocks; on the basis of completing the merging of the blocks, each set of grabbing mechanisms 3 can be used to The blocks are grasped with centralized side clamps, which solves the trouble of requiring manual assistance during actual handling operations, and the design of multiple groups of grasping structures greatly improves the stability, safety and reliability during the grasping process.
