Description

Technical Field

[0001] This invention specifically relates to a fully automatic concrete setting time measuring device with a robotic arm, and pertains to the field of concrete measuring equipment technology. Background Technology

[0002] Currently, most concrete setting time determinations are conducted manually or using semi-automatic equipment. The overall efficiency is very slow, especially during the processes of opening the concrete container, absorbing bleed water, and cleaning the probe. Furthermore, manual adjustment of the probe at different testing positions is required, hindering both accuracy and efficiency. Since the object of the test is concrete, dust and impurities often accumulate on the placement tray, causing uneven placement of the test tube and sample tilting, affecting the test data and the environment of the test tube. Insufficient cleaning is also a concern. Therefore, there is an urgent need for a fully automated concrete setting time determination device with a robotic arm to address these issues. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a fully automated concrete setting time measuring device with a robotic arm to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a fully automatic concrete setting time measuring device with a robotic arm, comprising a body, a test cylinder, and an electrical control system installed on the front side of the body to control various electrical components. The upper side of the body is equipped with, from right to left, a test cylinder placement rack for arranging multiple test cylinders, a multi-directional moving robotic arm for grasping the test cylinders and moving them forward, backward, up, down, left, and right, an opening mechanism for opening the test cylinder, an inclined water absorption mechanism for absorbing the water seeping from the inside of the test cylinder, a rotating mechanism for placing the opened test cylinder, and a needle insertion mechanism located above the rotating mechanism for inserting and measuring the concrete setting time inside the test cylinder.

[0005] A probe cleaning mechanism is movably arranged between the rotating mechanism and the needle lowering mechanism. The probe cleaning mechanism includes a cleaning box, which is movably located between the rotating mechanism and the needle lowering mechanism. A suction and sweeping assembly is provided at the bottom of the cleaning box for synchronously cleaning the upper side of the rotating mechanism.

[0006] The vacuuming and sweeping assembly includes an array of tubes arranged in an array at the bottom of the cleaning box, and each tube is interconnected. The tubes are connected to a vacuum pump via an air pipe. The vacuum pump is installed on one side of the cleaning box, and a dust filter box is installed on one side of the cleaning box. The dust filter box is connected to the dust outlet of the vacuum pump.

[0007] The bottom of the arranged tube is fixed and connected to multiple rubber suction tubes. The rubber suction tubes are in elastic contact with the upper side of the rotating mechanism. The tube cavity of the rubber suction tube is longitudinally provided with a middle baffle that divides the tube cavity into left and right channels. The bottom left and right sides of the rubber suction tube are provided with inclined surfaces. When the cleaning box moves left and right, the inclined surfaces of the rubber suction tubes are simultaneously driven to adapt to contact the upper surface of the rotating mechanism, and the dust is scraped left and right at the middle baffle. The dust is then suctioned under negative pressure through the separated left and right channels.

[0008] Preferably, the probe cleaning mechanism further includes a fixed frame mounted on the machine body. The fixed frame is equipped with a transverse guide rail and a transverse belt rotatably connected via a rotating shaft. The fixed frame is equipped with a second transmission motor for driving one of the rotating shafts of the transverse belt to rotate. A slider that slides linearly with the transverse guide rail is installed on one side of the cleaning box, and the cleaning box is locked to the transverse belt on one side.

[0009] Preferably, the rotating mechanism includes a movable frame, a longitudinal guide rail mounted on the upper side of the machine body, and a longitudinal push rod. The bottom of the movable frame is slidably connected to the longitudinal guide rail, and one side of the movable frame is locked to the telescopic end of the longitudinal push rod. Multiple drive shafts are vertically rotatably mounted on the upper side of the movable frame, and each drive shaft has a placement plate mounted on its top. The bottoms of the drive shafts are interconnected via a drive belt. A first drive motor is mounted on the movable frame, and a drive wheel is mounted on the shaft end of the first drive motor and connected to the drive belt of one of the drive shafts.

[0010] Preferably, the cleaning box is positioned laterally above each placement tray and elastically contacts the upper side of the placement tray via a rubber suction tube. When the placement tray rotates, the rubber suction tube performs lateral scraping and vacuuming to clean the upper side of the placement tray from all directions.

[0011] Preferably, the needle insertion mechanism includes multiple vertical push rods, each with a probe installed at its telescopic end. The probes are located above the cleaning box, and each probe corresponds to a placement plate. In conjunction with the use of the longitudinal push rods and the drive shaft, the probes are inserted into different positions of the concrete inside the test cylinder.

[0012] Preferably, the upper side cover of the test tube is provided with a tube cover, and a handle is installed on the top of the tube cover. The test tube placement rack has multiple test tubes arranged in layers, and each test tube corresponds to one side of the multi-directional moving robot arm. The end of the multi-directional moving robot arm is equipped with a rotating gripper mechanism for clamping and rotating the test tube. The rotating gripper mechanism includes a rotary motor installed at the end of the multi-directional moving robot arm, and the rotating shaft of the rotary motor is equipped with a tube gripper capable of opening and closing to clamp the test tube.

[0013] Preferably, a vertical pole is installed on the upper side of the machine body, and the lid opening mechanism and the tilting water suction mechanism are installed on the vertical pole from top to bottom. The lid opening mechanism includes an upper fixing plate fixed on the vertical pole and a lid clamp installed on the upper fixing plate for opening and closing.

[0014] Preferably, the tilting water absorption mechanism includes a lower fixing plate fixed on the upright and a water absorption pipe head locked on the lower fixing plate. The water absorption pipe head is connected to a water pump through a water pipe. With the clamping and rotation of the rotary motor, the test tube is tilted at a set angle to concentrate the water secretion. The water absorption pipe head makes full contact with the inside of the test tube.

[0015] By adopting the above technical solution, the present invention has the following advantages:

[0016] Firstly, this invention can automatically grab the test tubes to be tested sequentially onto the opening mechanism, the tilting water absorption mechanism, and the rotating motor to fully absorb the exudate water. The tubes are then placed on the rotating mechanism to facilitate the insertion of the needle mechanism into the concrete inside the test tube for testing. During the test, the rotating mechanism can be moved forward and backward with the longitudinal push rod, allowing the needle to be inserted into different positions of the concrete. Combined with the rotational characteristics of the placement plate itself, the needle can be positioned to correspond to different positions of the concrete inside the test tube from all directions, thereby improving the range of automatic testing. Through the automated electronic control system, the concrete penetration force value is automatically measured within a specified time interval, the penetration resistance of the sample is calculated, and the initial setting time and final setting time are obtained through the time-penetration resistance curve. This transforms the manual detection of setting time into automated detection, greatly improving work efficiency and accuracy.

[0017] Secondly, the active probe cleaning mechanism can be inserted into the cleaning box of the probe cleaning mechanism for cleaning after the corresponding probe has been measured. The left and right movement of the probe cleaning mechanism can not only avoid the placement plate being measured, but also move left and right at the same time during the measurement. The bottom suction and sweeping component can simultaneously and elastically scrape and absorb the cleaning of the upper surface of other placement plates. Moreover, it can be combined with the rotation of the placement plate itself to improve the cleaning range and cleaning effect of the placement plate. In other words, when measuring concrete, other probes can be cleaned at the same time. When cleaning the probe, the cleaning box can move left and right at the same time within a certain range, allowing the suction and sweeping component to clean the upper surface of other placement plates at the same time.

[0018] Thirdly, the central baffle divides the rubber suction and sweeping pipe cavity into two channels, left and right. Therefore, when the suction and sweeping assembly moves left and right for cleaning, the central baffle at the bottom of the rubber suction and sweeping pipe can hook the upper side of the placement tray and concentrate the dust in the two channels. Then, the dust pump is used to absorb the concentrated dust particles separately. At the same time, the bottom left and right sides of the rubber suction and sweeping pipe are provided with inclined surfaces. When the rubber suction and sweeping pipe scrapes and contacts the placement tray, it tilts. Therefore, the inclined surfaces can greatly adapt to the upper side of the placement tray and also leave a certain space for dust particles to enter the channel and be sucked away, which greatly improves the use effect and cleaning effect of the equipment.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figure 1-10 As shown, this invention provides a fully automatic concrete setting time measuring device with a robotic arm, including a body 1, a test cylinder 3, and an electrical control system installed on the front of the body 1 to control various electrical components. The upper side of the body 1 is equipped with, from right to left, a test cylinder placement rack 2 for arranging multiple test cylinders 3, a multi-directional moving robotic arm 4 for grasping the test cylinders 3 and moving them forward, backward, up, down, left, and right, an opening mechanism 5 for opening the test cylinders 3, an angled water absorption mechanism 6 for absorbing water seeping from the inside of the test cylinders 3, a rotating mechanism 7 for placing the opened test cylinders 3, and a device located above the rotating mechanism 7. A needle insertion mechanism 9 is used to insert and measure the setting time of concrete in the test tube 3; the upper side of the test tube 3 is covered with a tube cover 31, and a cover handle 32 is installed on the top of the tube cover 31. Multiple test tubes 3 are arranged in layers on the test tube placement rack 2, and each test tube 3 corresponds to one side of the multi-directional moving manipulator 4. The end of the multi-directional moving manipulator 4 is equipped with a rotating gripper mechanism 41 for clamping and rotating the test tube 3. The rotating gripper mechanism 41 includes a rotary motor 411 installed at the end of the multi-directional moving manipulator 4, and the shaft of the rotary motor 411 is equipped with a tube gripper 412 that can open and close to clamp the test tube 3.

[0033] A probe cleaning mechanism 8 is movably arranged between the rotating mechanism 7 and the needle lowering mechanism 9. The probe cleaning mechanism 8 includes a cleaning box 81. The cleaning box 81 can be an ultrasonic vibrating box in the prior art, which can quickly remove dirt from the surface of the object. The cleaning box 81 is movably located between the rotating mechanism 7 and the needle lowering mechanism 9, and a suction and sweeping assembly 80 is provided at the bottom of the cleaning box 81 for synchronously cleaning the upper side of the rotating mechanism 7.

[0034] Specifically, the vacuuming assembly 80 includes an array of tubes 801 arranged in an array at the bottom of the cleaning box 81, with each tube 801 interconnected. Each tube 801 is connected to a vacuum pump 802 via an air pipe. The vacuum pump 802 is installed on one side of the cleaning box 81, and a dust filter box 804 is installed on the other side of the cleaning box 81. The dust filter box 804 is connected to the dust outlet of the vacuum pump 802 and is used to filter the sucked-in dust particles. Multiple rubber vacuuming fittings 803 are fixed to and connected to the bottom of the tubes 801. These rubber vacuuming fittings 803 are in elastic contact with the upper side of the rotating mechanism 7, and the cavities of the rubber vacuuming fittings 803 are longitudinally arranged... A central baffle 8031 ​​is provided to divide the cavity into left and right channels. The bottom of the rubber suction tube 803 has inclined surfaces 8032 on both sides. The arrangement tube 801 is clamped to the bottom of the cleaning box 81 by clamps. Therefore, when the cleaning box 81 moves left and right, the inclined surfaces 8032 of the rubber suction tube 803 can be driven to adapt to contact the upper surface of the placement plate 73 of the rotating mechanism 7, leaving a certain space so as not to be completely blocked. The dust is scraped in a concentrated manner on the left and right sides through the central baffle 8031. Then, the two separated left and right channels are used to perform negative pressure dust suction on both sides, thereby achieving the effect of synchronous elastic concentrated scraping and dust suction.

[0035] In this embodiment, the probe cleaning mechanism 8 also includes a fixed frame 82 installed on the body 1. The fixed frame 82 is equipped with a transverse guide rail 83 and a transverse belt 84 rotatably connected by a rotating shaft. The fixed frame 82 is equipped with a second transmission motor 85 for driving one of the rotating shafts of the transverse belt 84 to rotate. A slider 86 that slides linearly with the transverse guide rail 83 is installed on one side of the cleaning box 81, and one side of the cleaning box 81 is locked to the transverse belt 84. This not only allows the suction and sweeping assembly 80 to clean the upper side of the rotating mechanism 7 from left to right, but also allows the left and right displacement of the cleaning box 81 to avoid the condensing and measuring needle insertion mechanism 9. The spatial layout is reasonable, and the probes 92 of the other needle insertion mechanism 9 can enter the cleaning box 81 for synchronous cleaning.

[0036] The rotating mechanism 7 includes a movable frame 71, a longitudinal guide rail 72 mounted on the upper side of the body 1, and a longitudinal push rod 76. The bottom of the movable frame 71 is slidably connected to the longitudinal guide rail 72, and one side of the movable frame 71 is locked to the telescopic end of the longitudinal push rod 76, allowing the longitudinal push rod 76 to push and pull the movable frame 71 to move back and forth. In conjunction with the rotation of the placement tray 73, the needle insertion mechanism 9 is inserted into different positions of the test tube 3 for testing. Three drive shafts 74 are vertically rotatably mounted on the upper side of the movable frame 71, and the top of each drive shaft 74 is correspondingly mounted with a placement tray 73. The bottoms of the drive shafts 74 are interconnected through a drive belt. A first drive motor 75 is mounted on the movable frame 71. The shaft end of the first drive motor 75 is mounted with a drive wheel connected to the drive belt of one of the drive shafts 74. In this way, the first drive motor 75 can synchronously drive the rotation of each placement tray 73 to cooperate with the omnidirectional suction and sweeping of the suction and sweeping assembly 80 and with the needle insertion mechanism 9 to allow the probe 92 to penetrate into different positions.

[0037] For example, the cleaning box 81 is positioned laterally above each placement tray 73 and elastically contacts the upper side of the placement tray 73 via a rubber suction tube 803. When the placement tray 73 rotates, the rubber suction tube 803 can scrape and vacuum from all directions, cleaning the upper side of the placement tray 73. The needle insertion mechanism 9 includes multiple vertical push rods 91, with a probe 92 installed at the telescopic end of each vertical push rod 91. The probes 92 are positioned above the cleaning box 81, and each probe 92 corresponds to a position above each placement tray 73. In conjunction with the longitudinal push rod 76 and the drive shaft 74, the probes 92 are inserted into different positions of the concrete inside the test cylinder 3.

[0038] The machine body 1 has a vertical pole 10 mounted on its upper side, and the cover opening mechanism 5 and the tilting water suction mechanism 6 are mounted on the vertical pole 10 from top to bottom. The cover opening mechanism 5 includes an upper fixing plate 51 fixed on the vertical pole 10 and a cover clamp 52 that opens and closes on the upper fixing plate 51. The tilting water suction mechanism 6 includes a lower fixing plate 61 fixed on the vertical pole 10 and a water suction head 62 locked on the lower fixing plate 61. The water suction head 62 is connected to a water pump through a water pipe. With the clamping and rotation of the rotary motor 411, the test cylinder 3 is tilted at a set angle to concentrate the water secretion. The water suction head 62 makes full contact with the inside of the test cylinder 3.

[0039] In a more specific implementation, this fully automatic concrete setting time measuring device includes a multi-directional moving manipulator 4 and a rotating gripper mechanism 41 for grasping and rotating the test cylinder 3. It works in conjunction with a cover opening mechanism 5, an inclined suction mechanism 6, a rotating mechanism 7, and a needle lowering mechanism 9. Simultaneously, a needle cleaning mechanism 8 and a suction and sweeping assembly 80 clean the needle 92 and efficiently clean the placement tray 73, greatly improving the equipment's working efficiency and effectiveness. Specifically, it includes the following steps:

[0040] The tester only needs to load the concrete sample into the test cylinder 3 and place the nine test cylinders 3 on the test cylinder placement rack 2. The test cylinders 3 do not affect each other. When it is necessary to test the corresponding test cylinder 3, the multi-directional moving manipulator 4 moves up, down, forward, backward and left and right in combination with the rotating gripper mechanism 41 to accurately grasp the test cylinder 3. It can stably move up, down and forward and backward smoothly according to the track and accurately reach the designated position. First, the test cylinder 3 is grasped to the cover opening mechanism 5, so that the cover handle 32 on the cover 31 is held by the cover gripper 52. Then the test cylinder 3 moves down to get off the cover 31 and is placed on the tilting water suction mechanism 6, so that the water suction head 62 is in the open test cylinder 3. At this time, the rotating motor 411 drives the cylinder gripper 412 to rotate, so that the test cylinder 3 tilts at a fixed angle or a set angle, and the concrete oozing water is concentrated on one side of the water suction head 62. According to the predetermined program, it tilts for a specified time, and then the water suction pump automatically sucks up the concrete oozing water through the water suction head 62.

[0041] After the water is absorbed, the test tube 3 is placed on one of the three placement trays 73 of the rotating mechanism 7. Then, the probe 92 of the needle insertion mechanism 9 can automatically select between 100mm², 50mm², and 20mm² specifications. According to a predetermined program, the probe is precisely and evenly inserted into the mortar to a depth of 25±2mm within 10±2s. At the same time, the force value at the insertion depth of 25±2mm is recorded in real time by the sensor. The force value is calculated by the electronic control system to select the probe for the next insertion. The first drive motor 75 and the drive belt synchronously rotate each placement tray 73, allowing the concrete mixture to rotate at a fixed amplitude. In addition, the longitudinal push rod 76 can longitudinally push each placement tray. The forward and backward displacement of 73 allows the probe 92 to correspond to different positions of the concrete mixture in each test cylinder 3 in all directions, ensuring that the probe will not penetrate into the tested position during testing; and when one probe 92 is measuring, the other probe 92 can simultaneously extend downward into the cleaning box 81 of the probe cleaning mechanism 8 for cleaning, ensuring that the surface of the probe 92 is clean and meets the requirements for each test. The cleaning box 81 of the probe cleaning mechanism 8 can move left and right along the transverse guide rail 83 under the drive of the second drive motor 85 and the transverse belt 84, thus avoiding the test cylinder 3 for normal testing. Moreover, when the cleaning box 81 moves left and right, the bottom suction and sweeping component 80 simultaneously performs elastic scraping and absorption cleaning on the upper side of other placement trays 73.

[0042] Specifically, the central baffle 8031 ​​divides the cavity of the rubber suction and sweeping pipe 803 into left and right channels. Therefore, when the suction and sweeping assembly 80 moves left and right for cleaning, the central baffle 8031 ​​at the bottom of the rubber suction and sweeping pipe 803 can hook onto the upper side of the sweeping placement tray 73 and concentrate the dust particles in the left and right channels. Then, the dust pump 802 absorbs the concentrated dust particles separately. At the same time, the bottom left and right sides of the rubber suction and sweeping pipe 803 are provided with inclined surfaces 8032. When the rubber suction and sweeping pipe 803 scrapes and contacts the placement tray 73, it tilts. Therefore, the inclined surfaces 8032 can greatly adapt to the upper side of the placement tray 73 and can also reserve space for... A certain amount of space allows dust particles to enter the channel and be sucked away. In addition, with the rotation of the placement plate 73 itself, the cleaning range and cleaning effect of the placement plate 73 can be improved. That is to say, when measuring concrete, other probes can be cleaned at the same time. When cleaning probe 92, the cleaning box 81 can be moved left and right at the same time within a certain range, so that the suction and sweeping component 80 can clean the upper surface of the other placement plate 73 at the same time, which greatly improves the use effect and cleaning effect of the equipment. The test cylinder 3 after the measurement is completed is clamped by the multi-directional moving robot arm 4 and returned to the test cylinder placement rack 2 along the original path, and the next test cylinder 3 is measured.
