[0031] The utility model provides a kind of test equipment of cleaning robot buffer shell subassembly, refer to Figures 1-3 The test equipment includes:
[0032] Base 100 is used to carry the cleaning robot 300 to be detected, and the cleaning robot 300 to be detected is provided with buffer shell subassembly, and the buffer shell subassembly includes buffer shell 310 and sensor arranged in the buffer shell;
[0033] Collision module 200, collision module 200 is used to collide with buffer shell 310;
[0034] Controller, the sensor in the buffer shell 310 and collision module 200 are electrically connected by controller;
[0035] The controller is configured to control the collision module 200 to collide with the buffer shell 310, and collect sensor signals in the buffer shell 310 when the collision module 200 collides with the buffer shell 310, and determine whether the buffer shell assembly is qualified according to the sensor signals.
[0036] The shape of the base 100 is not limited, and the diameter of the base 100 is usually greater than the width of the to-be-tested cleaning robot 300, so as to ensure that the to-be-tested cleaning robot 300 can be stably placed on the base 100.
[0037] The collision module 200 usually includes a driving mechanism and a collision mechanism driven by the driving mechanism. The shape of the collision module 200 can be set as needed, and one driving mechanism can drive multiple collision mechanisms, or the driving mechanism and the collision mechanism can be one-to-one correspondence. Preferably, the part of the collision module 200 that contacts the to-be-tested cleaning robot 300 can be made of different materials, such as wood, metal, plastic or rubber, to simulate the situation when the to-be-tested cleaning robot 300 collides with different types of obstacles, so that the detection result is more accurate.
[0038] The controller is electrically connected with the sensors in the buffer shell 310 and the collision module 200, and is configured to control the opening and closing of the collision module 200, and collect information of the sensors in the buffer shell 310 when the to-be-tested cleaning robot 300 is impacted. The controller usually includes a data processing device and a data transmission channel, such as a computer and a wire, for monitoring, recording and transmitting the impact test data of the buffer shell 310 of the to-be-tested cleaning robot 300. According to these data, the performance and reliability of the buffer shell 310 of the to-be-tested cleaning robot 300 can be further analyzed and evaluated, and the automation of the test process can be realized.
[0039] In the actual test process, first, the to-be-tested cleaning robot 300 is installed on the base 100, so that the buffer shell assembly is arranged opposite to the structure in the collision module 200 that contacts the buffer shell 310, and then the test is started. The controller outputs a control signal to the collision module 200, starts the collision module 200 and controls the collision module 200 to impact the buffer shell 310. If the controller successfully receives the collision signal transmitted by the sensor, it is verified that the buffer shell assembly can work normally when impacted. Then, the controller outputs a control signal again to close the collision module 200, at which time the sensor no longer transmits a collision signal. Finally, other to-be-tested cleaning robots 300 that need to be tested are replaced, and the previous test process is repeated.
[0040] In some embodiments, the force applied by the collision module 200 to the buffer shell 310 is adjustable.
[0041] Since the to-be-tested cleaning robot 300 may encounter various obstacles such as walls, stools, tables and chairs, toys and the like when working normally, different obstacles have different obstruction forces on the to-be-tested cleaning robot 300, and therefore the impact force of the collision module 200 is adjusted by the controller to simulate the situation that the to-be-tested cleaning robot 300 encounters different obstacles, so as to more comprehensively test the stability of the to-be-tested cleaning robot 300, obtain more test data, and ensure the quality of the buffer shell assembly.
[0042] As shown in Figure 1 In some embodiments, the collision module 200 includes a plurality of collision platforms, and the plurality of collision platforms are arranged around the buffer shell 310; and / or,
[0043] The installation position of the collision module 200 is adjustable.
[0044] The collision platform is a mechanism that can impact the buffer shell 310 of the to-be-tested cleaning robot 300, which can be a simple structure controlled manually, or an electrically controlled structure using a driving mechanism to control the collision, for example, the collision platform includes a support and a straight rod in sliding connection with the support, and a worker pushes the straight rod to impact the to-be-tested cleaning robot 300 to test the sensing condition of the buffer shell assembly, or drives the straight rod to impact the to-be-tested cleaning robot 300 by using a driving mechanism.
[0045] The plurality of collision platforms are arranged around the buffer shell 310, so that each position of the buffer shell 310 can be subjected to impact test. The collision platform and the base 100 can be connected in various ways, which can be fixedly arranged on the base 100, or can be detachably connected with the base 100. Preferably, in the embodiment, the collision platform is arranged around the base 100 in a detachable manner, so that the collision platform is easier to clean, maintain and replace. The collision platforms at different positions can impact the buffer shell 310 of the to-be-tested cleaning robot 300 from different directions, and the test results are more accurate and comprehensive.
[0046] In some embodiments, the installation position of the collision module 200 is adjustable. Since the collision mechanism of the collision module 200 has a limited collision stroke, in order to make the test equipment applicable to more models of to-be-tested cleaning robots 300, the installation position of the collision module 200 is set to be adjustable, so that more sizes of to-be-tested cleaning robots 300 can be adapted.
[0047] For example, a sliding rail is arranged on the base 100, and a sliding block that can slide with the sliding rail is arranged at the bottom of the collision module; or a plurality of mounting holes are arranged at different positions of the base 100, and a limiting column that is adapted to the mounting hole is arranged on the collision module 200, so that the collision module 200 is connected with the base 100 through plugging or threaded fixing; through the sliding fit and detachable connection, the position of the collision module 200 can be changed according to the model and installation position of the to-be-tested cleaning robot 300, so as to obtain better test effect.
[0048] As shown in Figures 1-3 In some embodiments, the plurality of collision platforms includes a plurality of first collision platforms 210 and a plurality of second collision platforms 220.
[0049] The first collision platforms 210 and the second collision platforms 220 apply different forces to the buffer shell 310; and / or,
[0050] The first collision platforms 210 and the second collision platforms 220 are arranged on the base 100 in a spaced manner around the buffer shell 310.
[0051] In the embodiment, the collision platforms are divided into the first collision platforms 210 and the second collision platforms 220 with different output, to simulate the situation that the to-be-tested cleaning robot 300 is impacted by different forces, and the first collision platforms 210 and the second collision platforms 220 are electrically connected with the controller, so that the controller can manage the opening and closing of the first collision platforms 210 and the second collision platforms 220, and adjust the impact time of the first collision platforms 210 and the second collision platforms 220, to simulate more complex environment, so as to comprehensively test the to-be-tested cleaning robot 300, and make the test result more accurate. Through the spaced arrangement of the collision platforms with different output, the buffer shell 310 in different regions is simultaneously impacted by different output, so that the test result is more accurate.
[0052] When testing, the to-be-tested cleaning robot 300 is placed on the base 100, the first collision platforms 210 and the second collision platforms 220 impact the to-be-tested cleaning robot 300 according to the preset output degree, and the controller collects the sensor signal in the buffer shell 310, so as to verify the impact resistance of the buffer shell 310 of the to-be-tested cleaning robot 300 and whether the internal sensor can accurately identify the signal.
[0053] As shown in Figures 1-3 In some embodiments, each of the first collision platforms 210 and the second collision platforms 220 includes an electromagnetic valve 230 and a push rod 240, the pushing direction of the push rod 240 is consistent with the movable direction of the buffer shell 310, and the front end of the push rod 240 is used to impact the buffer shell 310 of the to-be-tested cleaning robot 300.
[0054] Each of the collision platforms comprises an electromagnetic valve 230 and a push rod 240, and in operation, the push rod 240 is driven to move by controlling the electromagnetic valve 230. The push rod 240 is a component of the impact buffer shell 310, and the pushing direction of the push rod 240 is consistent with the movable direction of the buffer shell 310. For example, when the to-be-tested cleaning robot 300 is circular, the movable direction of the buffer shell 310 is generally towards the center of the to-be-tested cleaning robot 300, and then the push rod 240 also points to the center.
[0055] In some embodiments, when the push rod 240 is in the maximum extension position, the distance between the buffer shell 310 and the main body of the to-be-tested cleaning robot 300 is greater than or equal to 0. The purpose of such arrangement is to avoid problems of the to-be-tested cleaning robot 300 caused by the push rod 240 extending too long. It can be understood that the movement speed of the push rod 240, that is, the output size, can be controlled by the electromagnetic valve 230, so as to distinguish the first collision platform 210 and the second collision platform 220. Preferably, the buffer shell 310 can be impacted multiple times during testing to obtain more test data and further improve the accuracy of the test results.
[0056] As shown in FIG. 1, Figure 1 In some embodiments, the base 100 is provided with a turntable 110, and the to-be-tested cleaning robot 300 is placed on the turntable 110.
[0057] Placing the to-be-tested cleaning robot 300 on the turntable 110 facilitates the to-be-tested cleaning robot 300 to perform more complex actions and simulate more real scenarios during testing. For example, by controlling the rotation speed and direction of the turntable 110, various different environmental conditions can be simulated, including the sensing conditions of the to-be-tested cleaning robot 300 when being impacted under different rotation speeds and directions, so as to perform multi-angle and all-around collision tests on the to-be-tested cleaning robot 300. Moreover, rotating the turntable 110 can also reduce the number of collision platforms.
[0058] As shown in FIG. 1, Figure 2 In some embodiments, the testing device further comprises:
[0059] The lifting platform 120 is arranged on the base 100.
[0060] The lifting platform 120 is electrically connected to the controller, and the collision module 200 is arranged on the lifting platform 120.
[0061] The lifting platform 120 is arranged on the base 100, and can drive the collision module arranged on the lifting platform 120 to ascend or descend, so as to perform a test in the vertical direction, for example, to perform a collision test on the upper, middle and lower parts of the buffer shell 310, so as to better simulate the actual situation and obtain more accurate test results. At the same time, the arrangement of the lifting platform 120 can avoid impacting the fragile parts of the buffer shell 310, so as to avoid unnecessary damage.
[0062] Preferably, the lifting platform 120 is annular, so as to surround the to-be-tested cleaning robot 300, and the position of the collision module 200 is more convenient to set, so that the impact direction of the collision module 200 is more consistent with the movable direction of the buffer shell 310.
[0063] When the test starts, the controller first sends an instruction to the collision module 200 to control the collision module 200 to impact the buffer shell 310, and after receiving the sensor signal in the buffer shell 310, the controller sends a moving instruction to the lifting platform 120 to make the lifting platform 120 lift the collision module 200 to a suitable position, and then the controller controls the collision module 200 to impact the buffer shell 310 of the to-be-tested cleaning robot 300 again. After multiple tests, the controller controls the lifting platform 120 to return to the initial position. The movement of the lifting platform 120 is realized by the controller, so as to ensure that the height of each ascent is the same, and the repeatability and accuracy of the experimental results are ensured.
[0064] As shown in FIGS. Figure 1 and Figure 2 In some embodiments, the buffer shell 310 is provided with a structured light sensor, and the structured light sensor is provided with a baffle 130 corresponding to the position of the lifting platform 120.
[0065] The structured light sensor is used to emit a structured light beam and observe to obtain the three-dimensional shape and pose information of an object. The structured light sensor is usually arranged in front of and on both sides of the to-be-tested cleaning robot 300, that is, on the buffer shell 310. Therefore, when the buffer shell 310 is tested, the collision module 200 is installed on the lifting platform 120 corresponding to the position of the structured light sensor, and the collision module is controlled to impact the buffer shell 310 only after the lifting platform 120 ascends to avoid the structured light sensor, so as to avoid damaging the structured light sensor, and the impact performance of the buffer shell 310 around the structured light sensor can be tested, so that the test results are more accurate.
[0066] The baffle 130 is generally a rectangular plate for testing the structured light sensor. Since a collision platform can be arranged in front of the structured light sensor, a strip-shaped hole is formed in the middle of the baffle 130, so that the baffle 130 does not hinder the collision platform when the collision platform impacts the buffer shell 310 of the cleaning robot 300 to be tested. It can be understood that the length and width of the strip-shaped hole should be sufficient to accommodate the push rod 240, so that the push rod 240 does not rub or collide with the strip-shaped hole when the baffle 130 moves up and down with the lifting platform 120.
[0067] The utility model discloses a collision module 200 is hit to the buffer shell 310 of the cleaning robot 300 to be tested, simulates various situations that the cleaning robot 300 to be tested can meet in real scene, realizes the accurate test of the cleaning robot 300 to be tested, and the product is improved conveniently at the same time and selects the defective product, improves user experience.
[0068] The above-mentioned is only part or preferred embodiment of the utility model, and therefore cannot limit the range of protection of the utility model by words or drawings, and equivalent structural transformation is made by using the contents of the utility model specification and drawings under the concept of the whole of the utility model, or direct / indirect application in other related technical fields are included in the protection range of the utility model.
