[0033] Example
[0034] like Figures 1-6 As shown, this embodiment provides a concrete sample loading and unloading device in a compression testing system, comprising:
[0035] The double-layer conveyor belt line 100 for concrete sample trays is used to convey trays 200 to complete the incoming sample trays and the returning of empty trays;
[0036] The positioning and clamping device 300 of the concrete sample tray is used to position and clamp the sample tray so that the industrial robot can clamp the concrete sample at a fixed position;
[0037] A pallet lifting mechanism 400 is used to transfer empty pallets from the upper belt line to the lower belt line;
[0038] Industrial robot 500 is mainly used to load concrete samples into the compression testing machine and unload waste samples, and unload the waste samples after testing into the test sample retention tool;
[0039] The waste sample retention fixture 600 after inspection is used to carry the waste samples clamped by the industrial robot after the compression test.
[0040] The double-layer conveying belt line 100 for concrete sample trays comprises an upper and a lower belt line, wherein the upper belt line 110 is used for conveying sample trays, and the lower belt line 120 is used for returning empty trays.
[0041] The belt line 100 includes a belt 130, a frame 140 and a driving device. The belt 130 is arranged on both sides of the frame 140 and is the main part of the transmission carrier. The belt is preferably made of rubber material with high load-bearing capacity and wear resistance. The driving device is used to drive the belt line to operate and can be driven by a motor. The frame is used to support and fix the transmission of the belt line and can be made of steel.
[0042] The concrete sample tray is provided with a positioning and clamping device 300, including: two symmetrically arranged positioning plates 310, each of which is provided with a plurality of positioning grooves 311. In this embodiment, each positioning plate 310 is provided with three positioning grooves 311, and each positioning groove 311 can be used to place a group of trays 200. Each group of trays can be provided with three samples. A tray recess 210 corresponding to the positioning groove 311 is provided at the bottom of the tray 200, and a cylinder is provided under the positioning plate 310. When the tray recess 210 corresponds to the positioning groove 311, the cylinder is pushed out, driving the two positioning plates 310 to rise, and placing the tray 200 in the two positioning plates 310. The positioning of three trays can be completed at one time, which greatly improves the detection efficiency compared with the design of single-piece transmission and detection.
[0043] Furthermore, a belt line with a baffle is used, and ribs 131 are set on both sides of the belt 130, and a guide rail structure corresponding to the ribs 131 is set on the frame 140. For example, the vertical cross-section of the rib 131 can be set as a rectangle with an opening on the right side, and the guide rail mechanism on the frame 140 is embedded in this rib 131 for positioning. The belt 130 is positioned and guided by relying on the belt line rib 131, preventing the belt from shifting during transportation, avoiding the belt from shifting to both ends and being worn, or even getting stuck, thereby reducing production failures and extending the life of the belt line.
[0044] Through precise tray positioning and belt guide design, the specimen and tray can be placed in a more precise position to avoid deflection, making them more stable during transportation and reducing abnormal belt wear and jamming, thereby improving production efficiency and safety.
[0045] Furthermore, the drive motor uses a stepper motor, which is digitally controlled. The angle of each step of movement is precise, which can ensure very high operating accuracy and stability, effectively avoiding the errors and vibrations caused by acceleration, inertia, etc. of traditional motors, and maintaining a fixed distance between the pallets.
[0046] After the three groups of pallets are in place, they are positioned and clamped. The industrial robot 500 then takes the samples in turn to the compression testing machine 700 for compression testing. The upper empty pallet is transferred to the lower belt line through the lifting mechanism 400, completing the return of the empty pallet.
[0047] Furthermore, a clamping claw is provided at the end of the industrial robot 500, and the industrial robot loads the concrete sample into the compression testing machine and unloads the waste sample into the retention fixture through the end clamping claw. The end clamping claw includes a driving mechanism, a sensor and a clamping component. The driving mechanism generates power, so that the clamping component opens and closes according to a predetermined trajectory and force, thereby achieving the grasping and placement of the object. The sensor provides real-time position, force and speed feedback throughout the process to ensure the precise control of the clamping claw. The clamping component is usually made of two materials, hard and soft. It is preferred to use a flexible material. The flexible clamping claw mainly clamps the workpiece by deforming the flexible material, which can effectively buffer the impact force during the clamping process and reduce damage to the object. The flexible material is preferably rubber, which has good elasticity and wear resistance, and has good anti-slip properties. Furthermore, different clamping claws can be set to adapt to concrete samples of different sizes.
[0048] The lifting mechanism 400 preferably adopts a pneumatic chain lift, including a frame 410, a cylinder 420, a chain 430, a sprocket 440 and a lifting assembly 450. The cylinder 420 is fixed in the frame 410, the bottom end of the chain 430 is fixed on the frame 410, the top end of the chain 430 passes around the sprocket 440 and is connected to the lifting assembly 450, the chain 430 is engaged with the sprocket 440, and the top end of the piston rod of the cylinder 420 is connected to the sprocket 440. The lifting and lowering of the sprocket is driven by the lifting and lowering of the cylinder piston rod, thereby realizing the lifting and lowering of the lifting assembly.
[0049] Preferably, two sprockets 440 are symmetrically arranged on both sides of the cylinder 420, and two chains are respectively engaged with the two sprockets. The lifting and lowering of the lifting assembly are controlled by the two chains, so that the operation of the lifting assembly is more stable.
[0050] When in use, the cylinder is ventilated, the cylinder piston rod extends outward, and the sprocket moves with the cylinder piston rod. Because the sprocket is engaged with the chain, the sprocket drives the chain to move up and down. Because the bottom end of the chain is fixed and the top end of the chain is connected to the lifting assembly, the chain drives the lifting assembly to move up and down.
[0051] Furthermore, the lifting component 450 is a belt line. On the basis of the original double-sided belts, the belt line adds a middle belt. The length of the middle belt 451 is longer than the length of the belts 452 on both sides, which provides better support and transition for the pallet, ensuring that the pallet will not fall during the transmission on the belt.
[0052] After the test is completed, the industrial robot 500 will clamp the waste sample after inspection to the waste sample retention fixture 600 after inspection. The waste sample retention fixture 600 after inspection is used to recycle and store waste samples after compression resistance testing. The sample tray 200 after inspection is placed on the upper surface of the retention fixture 600. The retention fixture 600 is preferably a frame structure. The upper surface of the retention fixture 600 of the frame structure is preferably set to an embedded groove type. The size of the embedded groove is adapted to the size of the tray so that the tray can be completely placed in the inner shallow groove to ensure that it is not tilted and is placed stably. During work, a backpack AGV robot can be used to transport and transfer the sample tray and the retention fixture together. The backpack AGV robot runs to the bottom of the retention fixture, lifts the retention fixture off the ground by jacking, and then transports the sample tray and the retention fixture to the designated location.
[0053] Although the present invention has been described with reference to exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments. Various modifications and variations may be made to the exemplary embodiments described herein without departing from the scope or spirit of the present invention. The scope of the claims is to be given the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
