Description

Technical Field

[0001] The invention belongs to the technical field of seat detection, and specifically relates to a test of a line connection of a seat, and more particularly to a seat detection tool and a seat detection method. Background Art

[0002] The purpose of automobile seat circuit testing is to ensure the eligibility of the electrical functions of the seats, improve the quality and reliability of the seats, and provide technical support for production quality control and troubleshooting.

[0003] In the related art, multiple inspection stations are set up to inspect various functions of automobile seats. Too many inspection stations lead to complicated inspection procedures, low inspection efficiency, and a large space occupied by the inspection production line. At the same time, the inspection results of each inspection station need to be summarized and matched with the corresponding seats to be inspected. In the summary process, it is easy to have problems such as errors in the comparison of inspection results. Moreover, when inspecting, each station needs to first push the inspection head through a cylinder to complete the plugging of the inspection head and the seat to be inspected. The position accuracy of the seat to be inspected entering the inspection station is high, and the power supply of the seat to be inspected is completed, resulting in repeated power supply operations. The inspection head on each station needs to be additionally provided with a corresponding processing module, which increases the hardware cost and maintenance cost.

[0025] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0026] See also Figure 1 and Figure 2 At least one embodiment provides a seat inspection tool, including: a six-axis robot arm 100, a docking tool 200, a conveyor line 300 and a control module.

[0027] The insertion tool 200 is arranged on the six-axis robot arm 100 .

[0028] The conveyor line 300 is arranged on the side of the six-axis robot arm 100 and is used to convey the seats to be inspected. Figure 1 The conveyor line 300 in FIG. 1 only shows a partial structure.

[0029] The control module is electrically connected to the six-axis robot arm 100 and the insertion tooling 200 and is configured to control the six-axis robot arm 100 to drive the insertion tooling 200 to inspect the seat to be inspected.

[0030] Among them, the control module is configured to control the six-axis robot arm 100 to drive the insertion tooling 200 to plug the detection head 400 into the plug of the seat to be inspected, and then control the six-axis robot arm 100 to drive the insertion tooling 200 to inspect the buckles and functions of all buttons of the seat to be inspected according to the inspection process.

[0031] The six-axis robot arm 100 drives the insertion tool 200 to move to the corresponding position, completes the insertion of the detection head 400, and then drives the insertion tool 200 to perform functional detection on the buckles and buttons of the seat according to the detection process, thereby reducing the setting of the detection station, and only requires one insertion of the detection head 400 to complete the detection of all circuits of the seat, thereby improving the detection efficiency. At the same time, the fixed insertion method used in the relevant technology is changed to an adaptive insertion method driven by the six-axis robot arm 100, which reduces the demand for the position accuracy of the seat.

[0032] See also Figure 3 , the specific structure of the insertion tool 200 is described below.

[0033] The inserting tool 200 comprises: The mounting base plate 210 is disposed at the end of the six-axis robot arm 100. The mounting base plate 210 is integrally formed. In order to ensure structural strength, reinforcing ribs may be disposed on the mounting base plate 210.

[0035] The button trigger 230 is arranged on the mounting substrate 210 and is used to trigger the button of the seat to be detected under the drive of the six-axis robot 100. The button trigger 230 can click or toggle the corresponding button under the drive of the six-axis robot 100.

[0036] The clamping member 240 is disposed on the mounting substrate 210 and is used to clamp the detection head 400. The detection head 400 is clamped by the clamping member 240 to fix the detection head 400, and the position of the detection head 400 is adjusted adaptively by the six-axis robot 100, so as to meet the plugging requirements of plugs in different positions.

[0037] The guide connector 250 is arranged on the mounting substrate 210 and is used to be plugged into the buckle of the seat to be tested. The guide connector 250 simulates the plugging of the seat belt and the buckle, thereby realizing the detection of the buckle function.

[0038] The detection process of the control module is described below.

[0039] See also Figure 4 and Figure 7 , seat power supply detection, that is, the control module controls the six-axis robot arm 100 to drive the plugging tool 200 to plug the detection head 400 into the plug of the seat to be detected, that is: S211: Control the six-axis robot arm 100 to drive the clamping member 240 to clamp the detection head 400.

[0045] S216: Perform power supply test on the seat to be tested.

[0046] See also Figure 5 , buckle detection, that is, the control module controls the six-axis robot arm 100 to drive the insertion tool 200 to detect the function of the buckle of the seat to be detected, that is: S221: Sending a buckle detection instruction to the image acquisition module 220 .

[0047] S222: receiving the buckle image information sent by the image acquisition module 220.

[0055] S235: Acquire the posture adjustment signal fed back by the seat to be detected at this time, and complete the detection of the function of the button.

[0056] Please continue reading Figure 3 A six-dimensional torque sensor 260 is also provided at the connection between the mounting substrate 210 and the six-axis robot arm 100 ; the control module is electrically connected to the six-dimensional torque sensor 260 .

[0057] The six-dimensional torque sensor 260 is configured to detect six-dimensional torque information when the insertion tool 200 contacts the seat to be detected and send the six-dimensional torque information to the control module.

[0058] The control module is also configured to fine-tune the posture of the six-axis robot arm 100 according to the six-dimensional torque information to improve the matching accuracy between the insertion tool 200 and the seat to be tested.

[0059] The six-dimensional moment information includes the axial force information and axial moment information of the X-axis, Y-axis, and Z-axis. Figure 3 As shown, Fx represents the axial force information of the X-axis, Fy represents the axial force information of the Y-axis, Fz represents the axial force information of the Z-axis, Mx represents the axial moment information of the X-axis, My represents the axial moment information of the Y-axis, and Mz represents the axial moment information of the Z-axis.

[0060] The control module fine-tunes the posture of the six-axis robot arm 100 based on the six-dimensional torque information, namely: obtaining the current insertion direction of the insertion tooling 200; obtaining the torque change direction based on the changes in the axial force information and axial torque information of the X-axis, Y-axis, and Z-axis; and fine-tuning the six-axis robot arm 100 based on the insertion direction and the torque change direction so that the torque change direction coincides with the insertion direction.

[0061] Specifically, in each inspection process, the insertion direction of the insertion tool 200 and the seat to be inspected is a certain value. For example, the clamping member 240 inserts the clamped detection head 400 into the plug along the Y axis. If the torque change direction does not coincide with the insertion direction Y axis at this time, it indicates that the detection head 400 and the plug are not aligned at this time, and the posture of the detection head 400 needs to be fine-tuned until the torque change direction coincides with the insertion direction Y axis, thereby reducing the demand for insertion accuracy. The guide connector is inserted into the buckle along the Y axis, and the button trigger member 230 clicks along the Z axis or toggles the button along the Y axis.

[0062] Please continue reading Figure 3 The clamping member 240 includes: a clamping cylinder 241, a first clamping plate 242 and a second clamping plate 243; the first clamping plate 242 and the second clamping plate 243 are arranged opposite to each other; the clamping cylinder 241 is suitable for driving the first clamping plate 242 and the second clamping plate 243 to move toward or away from each other; an infrared sensor 244 is arranged on the first clamping plate 242 or the second clamping plate 243; the control module is electrically connected to the infrared sensor 244; the infrared sensor 244 is configured to send a detection signal to the control module when detecting that there is a detection head 400 between the first clamping plate 242 and the second clamping plate 243; when the control module receives the detection signal of the infrared sensor 244, it controls the first clamping plate 242 and the second clamping plate 243 to move toward each other to complete the clamping of the detection head 400.

[0063] It should be noted that the detection head 400 is placed in a fixed position.

[0064] See also Figure 8 and Fig. 9 The guide connector 250 includes: a connector block 251 , which is provided with a slot 2511 for connecting with the belt buckle, and a plurality of guide surfaces 2512 are provided at the notch of the slot 2511 ; and a locking tongue 252 , which is fixedly disposed in the connector block 251 .

[0065] See also Fig.10 At least one embodiment further provides a seat detection method applied to the seat detection tool as described above, the seat detection method comprising: S110: Control the six-axis robot arm 100 to drive the plugging tool 200 to plug the detection head 400 into the plug of the seat to be detected.

[0066] S120: Perform power supply detection on the seat to be detected.

[0067] S130: Control the six-axis robot arm 100 to drive the insertion tool 200 to be inserted into the belt buckle of the seat to be inspected.

The plug-in tool 200 is arranged on the six-axis robot 100. The conveyor line 300 is arranged on the side of the six-axis robot 100 and is used to convey the seat to be inspected. Figure 1 The conveyor line 300 in the figure only shows a partial structure. The control module is electrically connected to the six-axis robot 100 and the insertion fixture 200, and is configured to control the six-axis robot 100 to drive the insertion fixture 200 to detect the seat to be detected. Among them, the control module is configured to control the six-axis robot 100 to drive the insertion fixture 200 to plug the detection head 400 into the plug of the seat to be detected, and then control the six-axis robot 100 to drive the insertion fixture 200 to detect the buckle and all buttons of the seat to be detected according to the detection process.
