[0017] The following describes the embodiments of the present invention in conjunction with the accompanying drawings. The terms used in the embodiments of the present invention are only used to explain the specific embodiments of the present invention and are not intended to limit the present invention. The following describes the embodiments of the present application in conjunction with the accompanying drawings.

[0018] refer to Figure 1-Figure 2 An integrated electronic brake system controller performance test platform includes: The whole machine frame 1 is equipped with a host computer, a motor cabinet and electric control board, a wheel speed tester, a lighting lamp, an indicator light, an air source processor, and a series of control valves and sensors, which are conventional equipment used to test the power of the controller. Before the test, the user calibrates the test item information and qualified indicators in advance, enters the program version information of the corresponding test product in advance, and the qualified threshold range of the test item. The test actuator is installed in the whole machine frame 1, including a bottom mounting frame 21 and a top mounting frame 22, a lower test fixture 23 installed on the bottom mounting frame 21, and an upper test fixture 24 installed on the top mounting frame 22. The area between the lower test fixture 23 and the upper test fixture 24 is defined as a test station 6; The conveying mechanism 3 is across the entire machine frame 1, one end of which is set as the feeding end and the other end as the discharging end. The test piece is conveyed to the conveying mechanism 3 through the conveying mechanism 3. The conveying mechanism 3 adopts conventional chain plate conveying and belt conveying, etc., and refers to Figure 1 As shown, the conveying structure is supported on both sides and is suspended in the middle. Both ends of the workpiece to be tested are carried on the conveying structure for conveying.

[0019] When the piece to be tested is transported to the test station 6 by the conveying mechanism 3, the piece to be tested is pressed together by controlling the lower test tool 23, or the upper test tool 24, or simultaneously controlling the lower test tool 23 and the upper test tool 24. The lower test tool 23 and the upper test tool 24 are provided with corresponding jacks for connecting the plug-in of the piece to be tested. After pressing together, they can be electrically connected to the piece to be tested, and then the power-on test can be carried out according to the conventional test procedure; for example: the host computer sends a test request, the electromagnetic coil and the pump motor corresponding to the control valve are activated in sequence, the current of the power supply line of the valve and the pump motor in the connector changes, the host computer collects the current value through the current sensor to determine whether the relevant functional circuit is qualified, and the host computer program controls all valves to act in sequence, respectively determines the current range, and determines the functionality of the coil; the above-mentioned equipment for testing can be combined with corresponding equipment according to the test requirements; In one embodiment: Figure 1-Figure 3 As shown, the lower test fixture 23 and the bottom mounting frame 21, and the upper test fixture 24 and the top mounting frame 22 are all slidingly connected or elastically connected along the conveying direction perpendicular to the conveying mechanism 3, and a vibration mechanism is installed between the lower test fixture 23 and the bottom mounting frame 21 and / or between the upper test fixture 24 and the top mounting frame 22. The vibration mechanism is configured to controllably drive the lower test fixture 23, the test piece and the upper test fixture 24 to vibrate after the lower test fixture 23 and the upper test fixture 24 are pressed together; during the test process, the test piece is first powered on and tested in a static state, and then the vibration mechanism is started to control the lower test fixture 23, the test piece and the upper test fixture 24 to vibrate, and the test piece is tested in the vibrating state to simulate the state of the integrated electronic brake system controller when it is running on the car, so as to more effectively obtain relevant data of the test piece.

[0020] In one embodiment, reference Figure 3 As shown, both the bottom mounting frame 21 and the top mounting frame 22 include a base plate 25, and a pressing cylinder 26 is installed in the top mounting frame 22. Taking the control of the movement of the upper test tool 24 as an example, the pressing cylinder 26 is used to control the up and down movement of the corresponding base plate 25; the base plates 25 are each provided with a slide groove 41 perpendicular to the conveying direction of the conveying mechanism 3, and the lower test tool 23 and the upper test tool 24 are respectively installed in the slide groove 41 of the corresponding base plate 25 through a slider 42. The vibration mechanism is configured to control the lower test tool 23 and the upper test tool 24 to slide back and forth in the corresponding slide groove 41; The vibration mechanism in this embodiment includes a telescopic cylinder 43 , the telescopic end of the telescopic cylinder 43 is linked to the slider 42 , and the telescopic cylinder 43 is used to control the slider 42 to slide back and forth in the slide groove 41 .

[0021] When performing a dynamic test, the telescopic cylinder 43 (an electric telescopic cylinder 43, such as an electric hydraulic telescopic cylinder 43) is started, and the telescopic end of the telescopic cylinder 43 drives the slider 42 to reciprocate in the slide groove 41, thereby driving the base plate 25, the lower test tool 23, the upper test tool 24 and the test piece to move, performing the dynamic test, and controlling the slider 42 to reset after the test is completed.

[0022] Based on the above, an elastic member 44 is installed between the slider 42 and the inner wall of the slide groove 41, and the telescopic cylinder 43 is configured to perform the following actions: Action 1: Push the slider 42 to slide back and forth in the slide groove 41 at a constant speed to simulate the working state of the test piece under regular vibration; Action 2: Push the slider 42 in the slide groove 41 to move to the elastic member 44 to store energy, and the telescopic cylinder 43 retracts and disengages from the slider 42; the slider 42 reciprocates in the slide groove 41 under the action of the elastic member 44, which is used for the working state of the test piece under sealed irregular vibration; realize multi-working condition simulation test, and after the preset test time, the telescopic cylinder 43 extends and guides the slider 42 to reset.

[0023] For the retraction of the telescopic cylinder 43 and its separation from the slider 42, a structure such as electromagnetic adsorption can be used. When power is turned on, the telescopic end of the telescopic cylinder 43 generates magnetism or the corresponding side of the slider 42 generates magnetism, and the two are adsorbed and connected. After power is turned off, the magnetism is reduced, and the telescopic cylinder 43 retracts and separates from the slider 42; other conventional locking structures can also be used as needed to achieve locking connection or unlocking and separation at the connection between the two.

[0024] In another embodiment: Figure 4-Figure 5 As shown, a rotating structure is also installed on the bottom mounting frame 21, and the rotating structure includes a rotating shaft 51, and several connecting rods 52 installed on the rotating shaft 51. The distal end of each connecting rod 52 is equipped with a substrate 25, and each substrate 25 is equipped with a test lower tool 23. The rotating shaft 51 is used to rotate the substrate 25 and the test lower tool 23 to the test station 6, or rotate out of the test station 6, and a scrap recovery station 7 is provided below the test station 6. A stepper motor is provided at one end of the rotating shaft 51, and the stepper motor is controlled by the upper computer. The stepper motor is used to control the rotation of the rotating shaft 51. When rotating out of the test station 6, the test lower tool 23 carries the test piece to be tested and rotates synchronously to the scrap recovery station 7 to release the test piece.

[0025] In this embodiment, when a defective part is detected, the rotating shaft 51 drives the substrate 25 and the lower test fixture 23, as well as the defective part, to rotate to the defective part recovery station 7, thereby separating the defective part from the conveying mechanism 3 and independently recovering it. This eliminates the need for manual separation, thus achieving automated testing and improving test efficiency. In order to separate defective products from the conveying mechanism 3, a rotating motor 8 can be set between the connecting rod 52 and the base plate 25, and the base plate 25 can be rotated in the horizontal direction by rotating, so that the base plate 25, the test tool 23 and the defective products are rotated and separated from the conveying mechanism 3, and then rotated by the rotating shaft 51.

[0026] In this embodiment, reference Figure 4-Figure 5 As shown, a vacuum suction cup 9 is installed on the test lower tooling 23, and the vacuum suction cup 9 is configured to adsorb the test piece and stick it on the test lower tooling 23, or release the test piece from the test lower tooling 23; and a plurality of scrap recovery stations 7 are arranged under the test station 6, and the rotating shaft 51 drives the test lower tooling 23 to pass through all scrap recovery stations 7.

[0027] That is, when the test shows a defective product, based on the control of the upper computer, the vacuum suction cup 9 generates an adsorption force to adsorb the defective product on the test lower tooling 23. When the rotating shaft 51 rotates to the defective product recovery station 7, it can be released. By setting up multiple defective product recovery stations 7, the defective products in different situations can be classified and released to the corresponding defective product recovery station 7 according to the test results.

[0028] Further, in a specific embodiment, referring to Figure 5 As shown, a classification box 10 is provided at at least one scrap recovery station 7, and the classification box 10 includes several recovery bins 101. An electric telescopic rod 11 is installed at the vacuum suction cup 9 on the test lower tooling 23, and the electric telescopic rod 11 is configured to control the vacuum suction cup 9 to move away from the test lower tooling 23, or to reset.

[0029] Further, in a specific embodiment, referring to Figure 5 As shown, a transfer mechanism is installed between the classification box 10 and the conveying mechanism 3, and the transfer mechanism includes a transfer receiving plate 121. The transfer receiving plate 121 is configured to slide between the recovery bins 101 of the classification box 10, and a transfer suction cup 122 is provided on the transfer receiving plate 121. The transfer suction cup 122 receives the test piece released from the vacuum suction cup 9 through the transfer suction cup 122.

[0030] by Figure 5For example: a classification box 10 is set on the right side. When the rotating shaft 51 drives the defective products to rotate to the right side, the electric telescopic rod 11 is started, and the defective products are pushed to the transfer receiving plate 121. Then the transfer suction cup 122 on the transfer receiving plate 121 starts to absorb the defective products, and then the vacuum suction cup 9 is closed and separated from the defective products. The electric telescopic rod 11 is reset, and the transfer receiving plate 121 moves the defective products to the corresponding recovery bin 101 opening according to the information of the upper computer to release the defective products; for the movement of the transfer receiving plate 121, an independent control structure such as an electric slider 42 slide rail can be set on the transfer receiving plate 121, and it is controlled by the upper computer and works according to instructions; classified recycling is realized to facilitate subsequent discharge, and the entire process is automated.
