Description

Technical Field

[0001] The present invention belongs to the technical field of robot detection, and in particular relates to a collaborative robot reachability testing system and method. Background Art

[0002] Collaborative robots are widely used in industries such as industry and services, and they place increasing demands on object recognition accuracy and safe accessibility. Traditional collaborative robot object recognition and safe accessibility testing often relies on manual visual inspection, which is subjective and biased, resulting in low test accuracy. Summary of the Invention

[0003] The present invention aims to solve the above technical problems at least to a certain extent. To this end, the present invention aims to provide a collaborative robot reachability testing system and method.

[0004] The technical solution adopted in the present invention is:

[0005] A collaborative robot reachability testing system, comprising:

[0006] A test base is provided with a plurality of test holes, each of which is provided with a photoelectric sensor. A sealing cover is detachably installed at the opening of the test hole, and an identification mark is provided on the sealing cover;

[0007] The upper computer is electrically connected to the photoelectric sensor and the collaborative robot respectively. The upper computer is used to set a first sensing time T1 for the photoelectric sensor in the covered test hole, and set a second sensing time T2 for the photoelectric sensor in the test hole to be covered. After the collaborative robot test starts, the upper computer is used to determine whether the first sensing signal of the photoelectric sensor in the covered test hole is obtained within the first sensing time T1. If not, the test fails. If so, it is determined whether the second sensing signal of the photoelectric sensor in the test hole to be covered is obtained within the second sensing time T2. If not, the test fails. If so, the test is successful.

[0008] Preferably, a PVC pipe is installed in the test hole, and the sealing cover is connected to the PVC pipe by thread, magnetic attraction or adhesive; the test holes are arranged in rows and columns on the side of the test base.

[0009] Preferably, the host computer controls the photoelectric sensor to be normally open.

[0010] A testing method based on the collaborative robot reachability testing system comprises the following steps:

[0011] S1. Confirm the test points on the test base and set the first sensing time T1 and the second sensing time T2;

[0012] S2, the collaborative robot recognizes the sealing cover on the test base in automatic mode;

[0013] S3: The collaborative robot recognizes the sealing cover and operates it. When the sealing cover is opened within the first sensing time T1, the photoelectric sensor in the covered test hole converts the optical signal into an electrical signal to form a first sensing signal. The host computer records that the test point is successful, otherwise the test fails.

[0014] S4. The collaborative robot installs the sealing cover on the test hole to be covered at other test points within the second sensing time T2. The photoelectric sensor in the covered test hole senses the light shielding and forms a second sensing signal. The host computer records that the test of this test point is successful, otherwise the test fails.

[0015] The beneficial effects of the present invention are:

[0016] The collaborative robot reachability testing system provided by the present invention has a simple principle, low cost, and can be quickly arranged and installed. It can effectively improve the accuracy of collaborative robot object recognition and safe reachability detection, and can simultaneously measure and record information such as the number of successful tests and time.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and are not to be construed as limiting the present invention. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.

[0021] In the description of the embodiments of the present invention, it should be noted that the indicated orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the inventive product is typically placed when in use, or the orientations or positional relationships commonly understood by those skilled in the art. These are merely for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limitations on the present invention. In addition, the terms "first" and "second" are used only to distinguish descriptions and should not be understood as indicating or implying relative importance.

[0022] In the present invention, unless otherwise clearly specified and limited, terms such as "installed", "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components.

[0023] like Figure 1 As shown, a collaborative robot reachability testing system according to this embodiment includes a test base 1, a sealing cover 3, and a host computer 4. Multiple test holes 2 are arranged in rows and columns on the same side of the test base 1. Each test hole 2 is installed with a PVC pipe. The sealing cover 3 is detachably connected to the PVC pipe. When the sealing cover 3 is installed on the PVC pipe, it covers the test hole 2. The detachable connection between the sealing cover 3 and the PVC pipe is threaded, magnetic, or adhesive.

[0024] The sealing cover 3 is provided with an identification mark, which is a visual identification plate. The number of the sealing covers 3 is determined according to the test requirements, and the sealing covers 3 are made of PVC material.

[0025] Each test hole 2 is equipped with a photoelectric sensor. The host computer is electrically connected to the photoelectric sensor and the collaborative robot 5. The host computer 4 controls the photoelectric sensor to be normally open. The host computer 4 is used to set a first sensing time T1 for the photoelectric sensor in the covered test hole 2 and a second sensing time T2 for the photoelectric sensor in the test hole 2 to be covered. After the collaborative robot test begins, the host computer 4 determines whether the first sensing signal of the photoelectric sensor in the covered test hole 2 is obtained within the first sensing time T1. If not, the test fails. If so, the host computer 4 determines whether the second sensing signal of the photoelectric sensor in the test hole 2 to be covered is obtained within the second sensing time T2. If not, the test fails. If so, the host computer 4 determines whether the second sensing signal of the photoelectric sensor in the test hole 2 to be covered is obtained within the second sensing time T2. If not, the test fails. If so, the test succeeds.

[0026] The first sensing time T1 is determined by the test requirements, for example, it is set to 10s; the second sensing time T2 should be longer than the first sensing time T1, that is, the second sensing time T2 covers the first sensing time T1.

[0027] The host computer 4 is also used to output the test success result and has the function of storing data.

[0028] like Figure 2 As shown, a collaborative robot reachability testing method, using the collaborative robot reachability testing system described above, includes the following steps:

[0029] S1. After the system has completed inspection and debugging, function confirmation, and layout, the test points on the test base 1 are confirmed and the first sensing time T1 and the second sensing time T2 are set;

[0030] S2. The collaborative robot 5 recognizes the identification mark of the sealing cover 3 on the test base 1 in an automatic mode to determine the position of the sealing cover 3;

[0031] S3: The collaborative robot 5 recognizes the sealing cover 3 and operates it. When the sealing cover 3 is opened within the first sensing time T1, the photoelectric sensor in the covered test hole 2 converts the optical signal into an electrical signal to form a first sensing signal. The host computer 4 records that the test point is successful, otherwise the test fails.

[0032] S4: The collaborative robot 5 installs the sealing cover 3 on the test hole 2 to be covered at another test point within the second sensing time T2. The photoelectric sensor in the covered test hole 2 senses the light shielding and generates a second sensing signal. The host computer 4 records that the test at this test point is successful, otherwise the test fails.

[0033] S5. Repeat steps S3 and S4 according to the test requirements, and the host computer 4 records the test results and test time of each test point in real time.

[0034] It should be noted that the dimensions of the test base 1 , the dimensions of the PVC pipe, and the number of the test holes 2 are determined according to the test requirements.

[0035] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that falls within the scope defined by the claims of the present invention falls within the scope of protection of the present invention.
