In order to ensure a reliable closure, a blocking element is provided on the carrier plate 9, as shown in fig. 5, for blocking the access opening reserved in the housing 10 when the carrier plate 9 is moved into the test position.

In this embodiment, as shown in fig. 5, the back-and-forth sliding direction of the carrier plate is defined as a front-back direction, and the cover 10 has a rectangular structure as a whole, and the cover 10 specifically includes an upper baffle 101, a left baffle 103, a right baffle 102, and a rear baffle 104. The front ends of the upper baffle 101, the left baffle 103 and the right baffle 102 form an inlet and an outlet reserved at the front end of the cover 10, and the inlet and outlet test block 100 enters and exits the test space.

In this embodiment, the sealing member on the bearing plate 9 is used to splice with the inlet and outlet on the cover body 10, so as to ensure that the test block 100 can freely enter and exit the test space, and when in specific implementation, the cover body 10 is relatively fixedly installed on the frame of the test block bending tester, so that the installation is more convenient. Moreover, the cover body does not need to reciprocate, so that the driving force and a transmission structure additionally arranged are saved, and the self structure of the test block bending resistance tester can be optimized. As another implementation mode, the cover body can be integrally and fixedly arranged on the mounting frame, and the reciprocating sliding on the bearing plate can be utilized to meet the requirement of the test block on entering and exiting the test space.

As shown in fig. 5, the tailgate 104 of the cover 10 is directly secured to the rail mount 41, thereby fixedly connecting the tailgate 104 to the mounting frame 4 of the protective carrier. The tailgate 104 is mainly used for protecting and closing the openings formed by the rear ends of the upper barrier 101, the left barrier 103, and the right barrier 102. As another implementation mode, the rear baffle plate can be directly and fixedly assembled with the upper baffle plate, the left baffle plate and the right baffle plate, namely, the rear baffle plate is fixedly connected to the baffle plate module.

As shown in fig. 5 and 7, a front baffle 18 is fixedly attached to the front end of the carrier plate 9, and the front baffle 18 serves as the blocking member for blocking the access opening reserved in the housing 10 when the carrier plate 9 is moved to the test position.

It should be noted that, in order to realize a normal bending test, corresponding avoiding openings are respectively provided on the cover body 10 and the bearing plate 9, so that the corresponding upper pressure head 12 and lower pressure head normally enter the test space to perform the bending test. As shown in fig. 5, the upper barrier 101, the left barrier 103 and the right barrier 102 are respectively provided with a relief port at positions corresponding to the upper ram 12 so that the upper ram 12 normally enters the test space. And avoidance ports are respectively arranged at the positions of the bearing plate 9, the left baffle plate 103 and the right baffle plate 102 corresponding to the two lower pressure plates 13 of the lower pressure head, so that the two lower pressure plates 13 can normally enter and exit the test space. The avoiding openings on the left baffle plate 103 and the right baffle plate 102, which are matched with the upper pressure head 12, are positioned at the upper ends of the two side baffle plates, and the avoiding openings on the left baffle plate 103 and the right baffle plate 102, which are matched with the two lower pressure plates 13, are positioned at the lower ends of the two side baffle plates.

In addition, in order to ensure that the upper pressure head 12 normally enters the test space, a corresponding avoiding structure is also arranged on the connecting plate 17 of the lifting baffle module to avoid the upper pressure head 12, as shown in the embodiment of fig. 5.

As in the embodiment shown in fig. 5, since the carrier plate 9 is arranged on the rail housing 41, a lift driving mechanism that drives the two lower pressure plates 13 to lift is arranged on the lower side of the support table 1. In order to ensure that the two lower pressing plates 13 can normally lift, an avoidance structure is also arranged on the guide rail support 41 at a corresponding position corresponding to the avoidance opening on the bearing plate 9, and is used for avoiding the two lower pressing plates 13. Therefore, when the bending test machine specifically works, the two lower pressing plates 13 are arranged below the guide rail support 41, when the bearing plate 9 moves to a test position, the test block 100 moves into a test space at the moment, the lifting driving mechanism drives the two lower pressing plates 13 to lift, the two lower pressing plates 13 push the test block 100 upwards, the upper part of the test block 100 is in pressing contact with the upper pressing head 12, and at the moment, the upper pressing head 12 and the two lower pressing plates 13 form a three-point force application structure due to the fact that the upper pressing head 12 is positioned between the two lower pressing plates 13, and normal bending test can be guaranteed. After the test is completed, the two lower pressing plates 13 sink out of the test space and sink under the bearing plate 9 again, at this time, the test block 100 also falls on the bearing plate 9 again, and the bearing plate 9 can bear the transfer test block 100 to take out and put in place for the corresponding operator to take out the test block 100 after the test.

In addition, in the test block bending machine, a position sensor is provided on the rail mount 41 of the mounting frame 4 in order to improve the automation performance of the whole machine. When the carrying plate 9 moves to the test position of the carrying plate 9 with the test block 100, the carrying plate 9 triggers a corresponding position sensor, and the position sensor sends corresponding detection information to the control unit of the test block bending tester, at this time, the lifting driving mechanism on the test block bending tester drives the two lower pressing plates 13 to lift so as to cooperate with the upper pressing head 12 to perform bending test.

The position sensor can be a mechanical touch sensor, an electromagnetic induction sensor or a photoelectric triggering sensor for detecting the movement of the carrier plate 9 in place. It is possible for those skilled in the art to apply the test block bending tester as long as it can be mounted on the mounting frame 4 and normally detect that the carrier plate 9 is moved in place.

As shown in fig. 1, 5 to 7, the protective carrier device further comprises a sweeper 7, which sweeper 7 is arranged beside the mounting frame 4, as shown in fig. 5, the sweeper 7 being located in particular beside the lower support plate 14 of the rail support 41. After the carrying plate 9 moves to the picking and placing position of the carrying plate 9 with the test block 100, the test block 100 can be removed by a manipulator, and the sweeper 7 can automatically clean the large debris remained on the carrying plate 9.

As shown in fig. 5, the cleaner 7 specifically includes a pushing cleaner head 72, the pushing cleaner head 72 being disposed above the carrier plate 9 in the up-down direction, the pushing cleaner head 72 being driven by a cleaning cylinder 71 as a cleaning drive mechanism to reciprocate to clean debris on the carrier plate 9 at the pick-up and place.

The cleaning cylinder 71 is supported and placed on the supporting table 1 by the supporting frame 6 to mount the cleaning cylinder 71 on the test block bending tester.

As another embodiment, the cleaning cylinder 71 may be supported and mounted on the mounting frame 4 by a support frame. In addition, as an embodiment, the pushing cleaning head may adopt an electric push rod as a cleaning driving mechanism to drive the telescopic motion.

When the cleaning cylinder 71 drives the pushing cleaning head 72 to extend, the cleaning cylinder can push sundry scraps with larger particles on the bearing plate 9 away from the bearing plate 9 so as to achieve the cleaning purpose. Moreover, since the pushing cleaning head 72 is located above the carrier plate 9, the pushing cleaning head 72 has a lower side surface for facing the carrier plate 9, as shown in fig. 6, a dust collection opening 720 is provided on the lower side surface of the pushing cleaning head 72, and a dust collection channel communicating with the dust collection opening 720 is provided on the pushing cleaning head 72, and the dust collection channel provides a negative pressure suction force to perform dust collection treatment through the dust collection opening 720 when the pushing cleaning head 72 cleans sundries on the carrier plate 9. Therefore, by pushing the cleaning head 72, the debris with the size on the carrying plate 9 can be cleaned, so that the debris is prevented from affecting the subsequent bending test precision.

In the case of the carrying plate 9, since the carrying plate 9 is provided with the avoiding opening through which the two lower pressing plates 13 pass, when the pushing cleaning head 72 stretches reciprocally to clean, part of sundry scraps are easily pushed into the avoiding opening. To avoid accidents, as shown in fig. 5, regarding the lower support plate 14 on the rail support 41 for carrying the carrier plate 9 moving to the picking and placing position, a leak hole 141 may be disposed at a corresponding position of the lower support plate 14, where the leak hole 141 is used for corresponding to the avoiding opening on the carrier plate 9 moving to the picking and placing position, so as to allow impurities falling through the avoiding opening on the carrier plate 9 to be discharged, and further, impurities cannot be accumulated in the avoiding opening of the carrier plate 9.

When the bearing plate moves in place to trigger the position sensor, the position sensor sends out information, the lifting driving mechanism of the test block bending tester drives the two lower pressing plates 13 to move upwards, the two lower pressing plates 13 penetrate through the avoidance structure on the guide rail support 41 and the avoidance port on the bearing plate 9 to enter the test space, the test block 100 is pushed to move upwards, and the upper side of the test block 100 is in pressing contact with the upper pressing head 12. According to the requirement of the flexural test, the two lower pressing plates 13 can continuously push the test block 100 upwards until the test block 100 to be tested is broken, at this time, the pressure data of the pressure sensor 11 is read and recorded, and whether the test block 100 is qualified can be judged accordingly. In practice, the test block 100 may be pressurized at a predetermined pressure, and if the test block 100 is not broken, the test block 100 may be considered to be acceptable, and if the test block 100 is broken or broken, the test block may be considered to be unacceptable. The specific test mode can be determined according to specific test requirements.

After the bending test is finished, the lifting driving mechanism drives the two lower pressing plates 13 to sink to leave the test space, as shown in fig. 7, the bearing plate 9 carries the front baffle 18 and the test block 100 to move towards the taking and placing position together, and the front baffle 18 moves away to ensure that the test block 100 can be moved away through the inlet and the outlet. After the bearing plate 9 moves to the picking and placing position, the tested test block 100 can be picked up by an operator of the intelligent robot, sundry scraps on the bearing plate 9 are cleaned by pushing the sweeping head, and then a new test block 100 to be tested is placed on the bearing plate 9 by the operator of the intelligent robot, so that the next round of bending test is started.
