Description

Technical Field

[0001] This utility model relates to the field of automated inkjet coding technology for cement concrete test blocks, and in particular to an automatic inkjet coding device for concrete test blocks. Background Technology

[0002] In the construction industry, concrete is the most widely used building material. Every year, my country produces nearly 50 million sets of concrete test blocks for compressive strength testing. As a key basic indicator in engineering testing, the compressive strength of concrete is closely linked to the structural safety of building projects.

[0003] Numbering concrete test blocks is a complex many-to-many task. After obtaining a set of numbers, staff must accurately locate and number the blocks among numerous others. As the number of blocks increases, the difficulty of finding them rises exponentially. For a long time, testing institutions have relied primarily on manual numbering of concrete test blocks, which has undoubtedly resulted in high labor costs. Even with the advent of labeling methods, the problem of low search efficiency remains unresolved.

[0004] In recent years, automatic concrete marking machines have also been under research. Patent ZL202023107805.6 introduces a concrete test block marking device. This device uses two UV marking stations working together to mark concrete test blocks. However, this device uses a conveyor belt, requiring manual placement of each test block onto the conveyor belt. Under continuous operation, workers need to repeatedly pick up and put down the blocks, resulting in high labor intensity. In addition, after marking, the test blocks are randomly piled on the unloading cart by the operators. During curing, the test blocks need to be rearranged and placed in the curing room, which is also a lot of work. Therefore, the following marking device was developed. Marking does not require manual operation. The robotic arm automatically grabs the concrete test blocks according to a fixed design trajectory and automatically places the marked test blocks on a material rack, which is convenient for overall curing and retrieval. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automatic inkjet coding device for concrete test blocks, so as to solve the problem that workers need to repeatedly carry concrete test blocks, resulting in high labor intensity in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0007] An automatic coding device for concrete test blocks includes a frame, a feeding rack for placing concrete test blocks to be coded at the front of the frame, and a discharging rack for placing coded concrete test blocks at the rear of the frame; it also includes grippers located within the frame for clamping the concrete test blocks, first drive mechanisms for driving the grippers to move up and down on both the left and right sides of the frame, second drive mechanisms for driving the grippers to move left and right on the two first drive mechanisms, third drive mechanisms for driving the grippers to rotate back and forth on the second drive mechanisms, and a fourth drive mechanism connected to the grippers for driving the grippers to move back and forth on the third drive mechanism.

[0008] In one embodiment of the present invention, the first driving mechanism includes a first support seat mounted on the frame, a first servo motor mounted on the first support seat and used to drive the gripper to move up and down, a first lead screw connected to the output shaft of the first servo motor, and a first sleeve threadedly connected to the first lead screw. The second driving mechanism is mounted on the first sleeve, and a first slide rod slidably connected to the second driving mechanism is also mounted on the first support seat.

[0009] In one embodiment of the present invention, the second driving mechanism includes two second support seats respectively mounted on the first sleeve and slidably connected to the first slide rod, a second servo motor mounted on the second support seats for driving the gripper to move left and right, a second lead screw connected to the output shaft of the two second servo motors, and a second sleeve threadedly connected to the second lead screw. The third driving mechanism is mounted on the second sleeve, and the two second support seats are also provided with a second slide rod slidably connected to the third driving mechanism.

[0010] In one embodiment of the present invention, the third driving mechanism includes a third support seat mounted on the second sleeve and slidably connected to the second slide rod, a third servo motor mounted on the third support seat for driving the gripper to rotate back and forth, a rotating component connected to the output shaft of the third servo motor, and the fourth driving mechanism mounted on the rotating component.

[0011] In one embodiment of the present invention, the fourth driving mechanism includes a telescopic tube connected to the gripper and the rotating member respectively. The end of the telescopic tube away from the gripper is connected to a comprehensive pipeline. The comprehensive pipeline is provided with electric and pneumatic pipelines for controlling the extension and retraction of the telescopic tube.

[0012] In one embodiment of the present invention, a first UV nozzle, a second UV nozzle, and a barcode reader are provided on the top side of the frame corresponding to the concrete test block in the gripper. The first UV nozzle, the second UV nozzle, and the barcode reader are sequentially installed on the frame along the length direction of the frame. A chip identifier is also provided on the top side of the frame on both sides of the first UV nozzle and the barcode reader.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figure 1 and Figure 2 This utility model provides an automatic coding device for concrete test blocks, including a frame 1. A loading rack 2 is located at the front of the frame 1 for placing concrete test blocks 3 to be coded, and a unloading rack 4 is located at the rear of the frame 1 for placing completed coded concrete test blocks 3. Rollers are provided on the bottom sides of both the loading rack 2 and the unloading rack 4. A control panel for data display and program control is also provided on the frame 1. It should be noted that the gripper 5 picks up the concrete test blocks 3 according to a fixed trajectory for coding. After coding, the concrete test blocks 3 are placed orderly on the unloading rack 4. During curing, simply push the unloading rack 4; the rollers facilitate pushing the unloading rack 4 carrying the concrete test blocks 3 into the curing chamber, thus facilitating centralized curing and retrieval.

[0025] Please see Figure 4The system also includes grippers 5 located within the frame 1 for gripping concrete test blocks 3. First drive mechanisms 6 for driving the grippers 5 to move up and down are provided on both the left and right sides of the frame 1. The first drive mechanism 6 includes a first support base 601 mounted on the frame 1, a first servo motor 602 mounted on the first support base 601 for driving the grippers 5 to move up and down, a first lead screw 603 connected to the output shaft of the first servo motor 602, and a first sleeve 604 threadedly connected to the first lead screw 603. A second drive mechanism 7 is mounted on the first sleeve 604. A first slide rod 605 slidably connected to the second drive mechanism 7 is also mounted on the first support base 601. It should be noted that the rotation of the two first servo motors 602 drives the rotation of the two first lead screws 603, thereby enabling the two first sleeves 604 to move up and down, which in turn causes the second drive mechanism 7 to move up and down, ultimately driving the grippers 5 to move up and down.

[0026] Please see Figure 5 The two first drive mechanisms 6 are equipped with second drive mechanisms 7 for driving the gripper 5 to move left and right. Each second drive mechanism 7 includes two second support seats 701 respectively mounted on the first sleeve 604 and slidably connected to the first slide rod 605; a second servo motor 702 mounted on the second support seats 701 for driving the gripper 5 to move left and right; a second lead screw 703 connected to the output shafts of the two second servo motors 702; and a second sleeve 704 threadedly connected to the second lead screw 703. A third drive mechanism 8 is mounted on the second sleeve 704. The two second support seats 701 are also equipped with second slide rods 705 slidably connected to the third drive mechanism 8. It should be noted that the rotation of the two second servo motors 702 can drive the second lead screw 703 to rotate, thereby enabling the second sleeve 704 to move left and right, which in turn enables the third drive mechanism 8 to move left and right, ultimately driving the gripper 5 to move left and right.

[0027] Please see Figure 6 The second drive mechanism 7 is equipped with a third drive mechanism 8 for driving the gripper 5 to rotate back and forth. The third drive mechanism 8 includes a third support base 801 mounted on the second sleeve 704 and slidably connected to the second slide rod 705, a third servo motor 802 mounted on the third support base 801 for driving the gripper 5 to rotate back and forth, and a rotating component 803 connected to the output shaft of the third servo motor 802. A fourth drive mechanism 9 is mounted on the rotating component 803. It should be noted that the rotation of the third servo motor 802 can drive the rotating component 803 to rotate, thereby enabling the gripper 5 to rotate back and forth, and thus adjusting the rotation angle of the gripper 5.

[0028] Please see Figure 6The third drive mechanism 8 is equipped with a fourth drive mechanism 9 for driving the gripper 5 to move back and forth and connected to the gripper 5; wherein, the fourth drive mechanism 9 includes a telescopic tube 901 connected to the gripper 5 and the rotating member 803 respectively, and the end of the telescopic tube 901 away from the gripper 5 is connected to a comprehensive pipeline 902, and the comprehensive pipeline 902 is provided with electric and pneumatic pipelines for controlling the extension and retraction of the telescopic tube 901; it should be noted that under the action of the electric and pneumatic pipelines in the comprehensive pipeline 902, the telescopic tube 901 can be controlled to extend and retract, thereby enabling the gripper 5 to move back and forth.

[0029] Please see Figure 3 The top side of the frame 1 is provided with a first UV nozzle 10, a second UV nozzle 11 and a barcode reader 12 corresponding to the gripper 5. The first UV nozzle 10, the second UV nozzle 11 and the barcode reader 12 are installed sequentially on the frame 1 along the length of the frame 1. The top side of the frame 1 is also provided with a chip identifier 13 located on both sides of the first UV nozzle 10 and the barcode reader 12.

[0030] Specifically, when using this automatic inkjet printer, the gripper 5 is first controlled by two first servo motors 602 and a second servo motor 702 to move left, right, up, and down, grabbing the first piece of concrete from the loading rack 2 according to the programmed trajectory. After grabbing, the gripper 5 moves to the side of the chip reader 13 under the action of the two first servo motors 602 and the second servo motor 702 to identify the chip information. The central control system generates an information barcode. Then, the gripper 5 moves to below the first UV printhead 10, and the first UV printhead 10 sprays out white ink. Then, it moves to the area below the second UV printhead 11, which sprays out black ink for numbers and barcodes. It then moves to the area below the barcode reader 12 to scan and identify the information and confirm whether the coding is successful. After coding is completed, the gripper 5 is driven by the third servo motor 802 to rotate in the opposite direction. Under the action of the two first servo motors 602 and the second servo motor 702, it moves to the relative position of the empty material rack behind the coding machine. The gripper 5 extends to place the concrete test block 3 in the designated position of the unloading rack 4. The unloading rack 4, after being filled, can be pushed to the concrete curing room for curing.

[0031] In summary, this invention enables the gripper 5 to move up and down under the action of two first servo motors 602 and a first lead screw 603, to move left and right under the action of two second servo motors 702 and a second lead screw 703, to rotate back and forth under the action of a third servo motor 802 and a rotating component 803, and to move back and forth under the action of a telescopic rod and a comprehensive pipeline 902. This allows the gripper 5 to pick up the concrete test block 3 along a fixed trajectory for coding. After coding, the concrete test block 3 is placed orderly on the unloading rack 4 for centralized curing and retrieval, thus reducing the manual handling and placement of the concrete test block 3 before and after coding. This not only improves work efficiency but also reduces labor.

[0032] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
