Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0023] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use differences in names as a way to distinguish components, but use differences in components' functions as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to"; "substantially" means that those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0024] See also Figure 1 The embodiment of the present application provides a rhythm testing device 100, which is used to test the working rhythm of a device to be tested 200.

[0025] This specification does not limit the specific type of the device to be tested 200. The device to be tested 200 can be various robots, such as industrial robots, inspection robots or collaborative robots, or other devices with working rhythms such as CNC machining machines. In the present embodiment, the device to be tested 200 is a cylindrical coordinate industrial robot. The device to be tested 200 may include a main body 201 and a working end 203, and the working end 203 may be movably connected to the main body 201. The device to be tested 200 may also include an end driver (not shown in the figure) for driving the working end 203 to move relative to the main body 201, and the end driver may be arranged in the main body 201 and is transmission-connected to the working end 203. In some embodiments, the working end 203 may be the output end of the end driver.

[0026] The beat of the device under test 200 refers to the time required for the device under test 200 to move a unit distance or complete a specific task. In this embodiment, the beat testing device 100 is used to test the influence of the beat of the device under test 200 by recording the time of each beat of the device under test 200 and observing the time interval during the radiation resistance test of the device under test 200.

[0027] Please also see Figure 1 and Figure 2In this embodiment, the beat test device 100 may include a shielding room 10, a mounting seat 20, a detection component 30, a monitoring component 40 and a controller 50. The shielding room 10 is provided with a shielding space 12. In order to meet the requirements of the electromagnetic compatibility anti-interference level, in this embodiment, the shielding room 10 is an anechoic chamber, and a frequency sweep will be performed in the anechoic chamber. The mounting seat 20 is arranged in the shielding space 12, and it can be placed on the ground plane of the shielding room 10. The detection component 30 is arranged on the mounting seat 20, and the detection component 30 is provided with a detection area 33, and the detection area 33 is used to detect the movement of the working end 203 of the device to be tested 200. The monitoring component 40 includes a monitoring transmitter 41, a monitoring receiver 43 and an optical fiber cable 45. The monitoring transmitter 41 is arranged on the mounting seat 20, and the monitoring receiver 43 is arranged outside the shielding space 12. The optical fiber cable 45 transmits signals between the monitoring receiver 43 and the monitoring transmitter 41. The controller 50 is electrically connected to the detection component 30 and the monitoring transmitter 41, and is used to receive the detection data of the detection component 30.

[0028] In the radiation resistance test of the device to be tested 200, the device to be tested 200 is in the shielded space 12, and data can only be transmitted inside and outside the shielded space 12 through the optical fiber cable 45. The device to be tested 200 is located on one side of the mounting seat 20. When the device to be tested 200 is started and the frequency is scanned in the shielded space 12, it is ensured that the working end 203 can touch the detection area 33. In order to make the height of the device to be tested 200 and the height of the detection area 33 more compatible, in this embodiment, a base for placing the device to be tested 200 can be provided in the shielded space 12.

[0029] When the beat test device 100 is used, the device to be tested 200 is started, and the working end 203 of the device to be tested 200 enters the detection area 33 and then leaves the detection area 33 to complete a beat, and then repeats the next beat. When the working end 203 touches the detection area 33, the detection component 30 transmits a signal to the controller 50, and the controller 50 records it. When the working end 203 touches the detection area 33 again, the detection component 30 transmits a signal to the controller 50, and the controller 50 records it again, thereby obtaining the time of one beat of the device to be tested 200, and the time signal is the above-mentioned detection data. The controller 50 transmits the detection data to the monitoring transmitter 41, and the monitoring transmitter 41 converts it into an optical signal and transmits it to the monitoring receiver 43 outside the shielded space 12 through the optical fiber cable 45. In this way, the time interval is repeatedly recorded and a curve is formed. During this period, the device to be tested 200 is swept in the shielded space 12. By manually observing or confirming the time interval curve through the processor of the controller 50, it can be confirmed which frequency has an impact on the beat of the device to be tested 200.

[0030] In the beat test device 100 provided in the present application, the shielded room 10 forms an effective shielding effect, and the monitoring transmitter 41 transmits the signal to the outside of the shielded space 12 through the optical fiber cable 45. The signal propagation of the optical fiber cable 45 does not depend on the flow of current, thereby avoiding the electromagnetic induction interference of the beat test process caused by the flow of current, which not only meets the beat performance indicator monitoring requirements of the device to be tested 200 during the actual test process, but also meets the electromagnetic compatibility anti-interference level requirements.

[0031] In this application, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like 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 it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In this embodiment, the shielding room 10 forms a closed space, and the shielding space 12 is electromagnetically isolated from the outside world, which plays an effective shielding role when the beat test device 100 is used, and meets the requirements of the electromagnetic compatibility anti-interference level.

[0033] See also Figure 3 In this embodiment, the mounting seat 20 may include a support frame 21 and a mounting frame 23. The support frame 21 may be placed or fixed on the ground plane of the shielding room 10. The support frame 21 is a hollow frame that is roughly in the shape of a cube. The support frame 21 may be formed by splicing a plurality of aluminum profiles. The support frame 21 is used to support other structures of the beat test device 100. The mounting frame 23 is connected to the side of the support frame 21 that is away from the ground plane of the shielding room 10, and is used to install the detection component 30. The mounting frame 23 includes a mounting substrate 232 and a first mounting cover 234. The mounting substrate 232 is connected to the support frame 21. The mounting substrate 232 is roughly in the shape of a rectangular frame, and the detection component 30 is arranged on the mounting substrate 232. The first mounting cover 234 is connected to the mounting substrate 232 and is covered outside the detection component 30. It is used to protect the detection component 30 and prevent the influence of the frequency sweep in the shielding room 10 on the detection component 30, thereby improving the detection accuracy. The shape of the first mounting cover 234 matches the shape of the mounting substrate 232 , and the first mounting cover 234 is also substantially in the shape of a rectangular frame.

[0034] Please also see Figure 3 and Figure 4The detection assembly 30 is arranged between the first mounting cover 234 and the mounting substrate 232. The detection assembly 30 may include a detection transmitter 32 and a detection receiver 34. The detection transmitter 32 and the detection receiver 34 are respectively arranged on opposite sides of the mounting substrate 232. The detection transmitter 32 is used to transmit signals, and the detection receiver 34 is used to receive signals transmitted by the detection transmitter 32. The detection transmitter 32 and the detection receiver 34 are relatively spaced to form the above-mentioned detection area 33. The first mounting cover 234 surrounds the detection area 33 and covers the detection transmitter 32 and the detection receiver 34. In order to facilitate the signal transmission between the detection transmitter 32 and the detection receiver 34, the first mounting cover 234 is provided with a clearance opening 235 on both opposite side walls. The two clearance openings 235 correspond to the detection transmitter 32 and the detection receiver 34 respectively. The detection transmitter 32 and the detection receiver 34 transmit signals through the two clearance openings 235.

[0035] This specification does not limit the specific type of the detection component 30. For example, the detection component 30 can be a photoelectric switch, and the detection transmitter 32 is the transmitting end of the photoelectric switch, and the detection receiver 34 is the receiving end of the photoelectric switch. In this embodiment, the detection component 30 is a safety grating component, the detection transmitter 32 is the grating transmitting end, and the detection receiver 34 is the grating receiving end. The grating transmitting end can use electromagnetic waves such as infrared or laser beams as the transmitting signal, and the grating receiving end can use photodiodes or other similar components to receive the signal. When the working end 203 (such as Figure 1 When the working end 203 enters the detection area 33, it will block part or all of the light beam, causing the reflected signal to weaken or disappear. The detection component 30 transmits a signal to the controller 50 each time the working end 203 enters the detection area 33, and the controller 50 records and obtains the time of each beat.

[0036] In order to increase the applicability of the detection component 30, in this embodiment, the beat test device 100 may further include an adjustment component 70, which is disposed between the mounting substrate 232 and the support frame 21, and the adjustment component 70 is used to adjust the distance between the mounting substrate 232 and the support frame 21 to adjust the position of the detection area 33. The adjustment component 70 makes the height of the detection area 33 adjustable, so that the detection component 30 can be applied to the device 200 to be tested with a larger height range.

[0037] The adjustment assembly 70 may include a sliding bearing 72, an adjustment shaft 74, and a fixing member 76. The sliding bearing 72 is connected to the support frame 21. Specifically, the support frame 21 may include a support frame 212 and a mounting plate 214. The support frame 212 is placed on the ground plane of the shielding room 10. The mounting plate 214 may be fixedly connected to the side of the support frame 212 away from the ground plane of the shielding room 10 by screws, and the mounting plate 214 is spaced apart from the ground plane of the shielding room 10. The sliding bearing 72 may be fixedly connected to the mounting plate 214. The adjustment shaft 74 may be slidably inserted into the sliding bearing 72. The top end of the adjustment shaft 74 (the end of the adjustment shaft 74 away from the ground plane of the shielding room 10) is fixedly connected to the mounting base plate 232. The sliding direction of the adjustment shaft 74 is substantially perpendicular to the ground plane of the shielding room 10. The fixing member 76 may be movably connected between the sliding bearing 72 and the adjustment shaft 74.

[0038] When the device under test 200 (such as Figure 1 When there is a height difference between the detection area 33 and the detection area 33, so that the working end 203 cannot touch the detection area 33 even in the start-up state, the worker can manually adjust the height of the detection area 33. Specifically, the worker can hold the mounting base plate 232, pull the mounting base plate 232 and the detection assembly 30 thereon and other structures upward as a whole, and the adjustment shaft 74 slides relative to the sliding bearing 72 to provide a guide for the adjustment of the mounting base plate 232. After the detection area 33 is adjusted to a suitable height, the worker connects the fixing member 76 between the sliding bearing 72 and the adjusting shaft 74 to fix the position of the mounting base plate 232.

[0039] The present specification does not limit the specific type of the fixing member 76. For example, the fixing member 76 may be a fixing structure such as a screw, a pin, or a jackscrew. In the present embodiment, the fixing member 76 is a jackscrew. The fixing member 76 is disposed between the sliding bearing 72 and the adjusting shaft 74. When the fixing member 76 is tightened, the sliding bearing 72 and the adjusting shaft 74 are relatively fixed. When the fixing member 76 is loosened, the adjusting shaft 74 can slide relative to the sliding bearing 72.

[0040] In the description of the present application, it should be understood that terms such as "length", "width", "thickness", "up", "down", "front", "back", "left", "right", and "inside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only used to simplify the description of the present application and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present application.

[0041] In this embodiment, the mounting substrate 232 is in the shape of a rectangular frame. In order to improve the stability of the mounting and adjustment of the mounting substrate 232, the number of mounting plates 214 can be set to two, and the two mounting plates 214 are respectively located on both sides of the mounting substrate 232. The number of sliding bearings 72 can be set to four, and the four sliding bearings 72 are distributed on the two mounting plates 214, and the positions of the four sliding bearings 72 correspond to the positions of the four corners of the mounting substrate 232 in the vertical direction. Correspondingly, the number of adjustment shafts 74 is set to four, and the number of fixing members 76 is also set to four. The four adjustment shafts 74, the four fixing members 76, and the four sliding bearings 72 are arranged in a one-to-one correspondence, which improves the stability of the height adjustment of the detection area 33.

[0042] Please also see Figure 2 and Figure 3 In this embodiment, the beat test device 100 may further include a battery 60, which is mounted on the mounting frame 23. The battery 60 is electrically connected to the detection component 30, the controller 50 and the monitoring transmitter 41, and the battery 60 is used to power the detection component 30, the controller 50 and the monitoring transmitter 41. In order to facilitate the installation of the battery 60, in this embodiment, the mounting frame 23 may further include a second mounting cover 236, and the second mounting cover 236 is connected to the side of the mounting substrate 232 away from the first mounting cover 234. The battery 60 is arranged between the mounting substrate 232 and the second mounting cover 236. The battery 60 of the beat test device 100 is built-in, and the shielding room 10 defines the shielding space 12, which further improves the effectiveness of the shielding effect.

[0043] The controller 50 is disposed between the second mounting cover 236 and the mounting substrate 232. The controller 50 is electrically connected to the detection component 30 and the monitoring transmitter 41. The controller 50 is used to record the time interval between the detection area 33 detecting the working end 203 twice, and transmit it to the monitoring transmitter 41. This specification does not limit the specific type of the controller 50. In this embodiment, the controller 50 can be a PLC (programmable logic controller). This specification does not limit the electrical connection between the controller 50 and the detection component 30, and between the controller 50 and the monitoring transmitter 41. As an example, the beat test device 100 can also include a data cable 52 and a network cable 54. The controller 50 is electrically connected to the detection component 30 through the data cable 52, and the controller 50 is electrically connected to the monitoring transmitter 41 through the network cable 54.

[0044] In this embodiment, the monitoring component 40 is used to transmit signals inside and outside the shielded space 12. The monitoring transmitter 41 of the monitoring component 40 is also arranged between the second mounting cover 236 and the mounting substrate 232. The monitoring component 40 is used to convert the electrical signal transmitted by the controller 50 into an optical signal through optical coupling isolation, and then transmit it to the outside of the shielded space 12 through the optical fiber cable 45. In this embodiment, the monitoring transmitter 41 adopts an optical fiber transmitter, which may include an optical modulator and an optical fiber coupler; the monitoring receiver 43 adopts an optical fiber receiver, which may include an optical detector inside the optical fiber receiver. The monitoring transmitter 41 is used to convert the electrical signal into an optical signal, and guide it to the optical fiber cable 45 through the optical fiber coupler. The monitoring receiver 43 is used to guide the optical signal from the optical fiber cable 45 to the optical detector inside it, and convert it into an electrical signal. The monitoring component 40 converts the electrical signal into an optical signal and transmits it to the outside of the shielded space 12, further ensuring that the requirements of the electromagnetic compatibility anti-interference level are met.

[0045] In some embodiments, the beat test device 100 may further include a host computer 80, which is used to obtain the beat monitoring data of the device to be tested 200 in real time and analyze the impact of different radiations on the system performance of the device to be tested 200. The host computer 80 is arranged outside the shielded space 12 and is electrically connected to the monitoring receiver 43. The host computer 80 can be electrically connected to the monitoring receiver 43 via a network cable. The monitoring receiver 43 converts the optical signal into an electrical signal and transmits it to the host computer 80 for monitoring.

[0046] When the beat test device 100 provided in the embodiment of the present application is used, the device to be tested 200 is started, and the working end 203 of the device to be tested 200 enters the detection area 33 and then leaves the detection area 33, and then repeats the next beat. When the working end 203 touches the detection area 33, the detection component 30 transmits a signal to the controller 50, and the controller 50 records it. When the working end 203 touches the detection area 33 again, the detection component 30 transmits a signal to the controller 50, and the controller 50 records it again, thereby obtaining the time of one beat of the device to be tested 200. The controller 50 sends the time signal to the monitoring transmitter 41, and the monitoring transmitter 41 converts it into an optical signal and transmits it to the monitoring receiver 43 outside the shielded space 12 through the optical fiber cable 45. In this way, the time interval is repeatedly recorded and a curve is formed. During this period, the device to be tested 200 is swept in the shielded space 12. By observing the time interval curve, it can be confirmed which frequency has an impact on the beat of the device to be tested 200.

[0047] In the beat test device 100 provided in the present application, the shielding room 10 forms an effective shielding effect, and the monitoring transmitter 41 transmits the signal to the outside of the shielding space 12 through the optical fiber cable 45, which not only meets the beat performance indicator monitoring requirements of the device to be tested 200 during the actual test process, but also meets the electromagnetic compatibility anti-interference level requirements.
