DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1 , Figure 2 As shown, the actuator function test equipment includes a loading area and a test area 2. The loading area includes a material transfer mechanism 1 3, a material transfer mechanism 2 4, a material transfer mechanism 3 5 and a loading platform 6. The test area 2 includes multiple test stations, each test station is equipped with a test mechanism 13, and the multiple test mechanisms 13 are evenly distributed in the test area 2 in sequence.

[0024] The material transfer mechanism 1 3 and the material transfer mechanism 2 4 reciprocate on the moving track 1 9, and the material transfer mechanism 3 5 reciprocates on the moving track 3 11. The moving track 1 9 is provided with a slider that drives the material transfer mechanism 1 3 and the material transfer mechanism 2 4 to move, and the moving track 3 11 is also provided with a slider that drives the material transfer mechanism 3 5 to move. The working principle of the sliding connection between the slider and the moving track is the same as the working principle of the moving module in the prior art, which will not be described in detail here.

[0025] Specifically, the material transfer mechanism 1 3 is used to transfer the workpiece 100 on the stage 6 to the test area 2, the material transfer mechanism 3 5 is used to transfer the workpiece 100 on the stage 6 to the auxiliary table 14 on the moving track 2 10, and the material transfer mechanism 2 4 is used to transfer the workpiece 100 on the auxiliary table 14 to the test area 2. The moving track 1 9, the moving track 2 10, and the moving track 3 11 are arranged in parallel beside multiple test stations.

[0026] In addition, both the stage 6 and the auxiliary stage 14 are provided with molds for clamping the workpiece 100. The stage 6 is used to receive the workpiece 100 to be tested transferred from the previous process, and the auxiliary stage 14 is used to receive the workpiece 100 transferred by the material transfer mechanism 3 5.

[0027] Through the sliding cooperation between the material transfer mechanism 3 and the moving track 9, the material transfer mechanism 3 transfers the workpiece 100 on the stage 6 to the test mechanism 13 in the test area 2. According to the position of the test mechanism 13, starting from the test mechanism 13 close to the stage 6, the material is loaded in sequence according to the position. When the material transfer mechanism 3 transfers the workpiece 100, it needs to reciprocate on the moving track 9, and the farther the test mechanism 13 to be transferred is from the stage 6, the longer the movement stroke of the material transfer mechanism 3 is.

[0028] When the material transfer mechanism 1 3 is unable to transfer the workpiece 100 on the loading platform 6 in time, the material transfer mechanism 3 5 transfers the workpiece 100 on the loading platform 6 to the auxiliary table 14 on the moving track 2 10 via the moving track 3 11, wherein the auxiliary table 14 is slidably connected to the moving track 2 10 and can reciprocate on the moving track 2 10.

[0029] Then, through the cooperation between the material transfer mechanism 2 4 and the moving track 1 9 , the material transfer mechanism 2 4 transfers the workpiece 100 on the auxiliary table 14 to the testing mechanism 13 of the testing area 2 .

[0030] It should be noted that, no matter the workpiece 100 is transferred to the test area 2 through the material transfer mechanism 1 3 or the material transfer mechanism 2 4 , the materials need to be loaded in sequence according to the positional relationship of the test mechanism 13 .

[0031] The material transfer mechanism 3 5 is used to perform stroke compensation on the material transfer mechanism 1 3 to prevent the workpiece 100 from being stranded on the stage 6. The material transfer mechanism 1 3 and the material transfer mechanism 2 4 cooperate with each other to realize sequential loading of multiple test stations, and uninterrupted operation of the loading process is achieved, which can effectively improve the test efficiency.

[0032] like Figure 3 , Figure 4 As shown, the material transfer mechanism 1 3, the material transfer mechanism 2 4, and the material transfer mechanism 3 5 all include a clamping assembly 15, and the clamping assembly 15 includes a clamping jaw 1502 driven by a cylinder 1501 to pick up and place the workpiece 100. The cylinder 1501 drives the clamping jaw 1502 to move, so as to realize the picking and placing operation of the workpiece 100, and facilitate the transportation of the workpiece 100.

[0033] In addition, the head end and the tail end of the moving track 10 are respectively equipped with a code scanning part 17 and a code scanning part 28. The code scanning part 17 is used to scan the workpiece 100 transferred by the material transfer mechanism 13, and the code scanning part 28 is used to scan the workpiece 100 transferred by the material transfer mechanism 24. After the material transfer mechanism 13 clamps the workpiece 100 on the stage 6, it is first scanned by the code scanning part 17, and then transferred to the test area 2; similarly, after the material transfer mechanism 24 clamps the workpiece 100 on the auxiliary table 14, it is first scanned by the code scanning part 28, and then transferred to the test area 2. By scanning the two-dimensional code configured on the workpiece 100 by the code scanning part 17 and the code scanning part 28, the information of the workpiece 100 can be obtained, which is convenient for information management.

[0034] The loading area and the testing area 2 are arranged on the workbench 1. The workbench 1 is also provided with a waste collection area 12 at the end of the testing area 2 for collecting unqualified workpieces 100. After the workpieces 100 are tested by the testing mechanism 13, qualified workpieces 100 are transferred to the next process, while unqualified workpieces 100 are transferred to the waste collection area 12 for centralized processing.

[0035] It should be noted that the workbench 1 is equipped with multiple photoelectric sensors for detecting whether there is a workpiece 100 in the detection area, which facilitates the coordinated loading between the material transfer mechanism 1 3, the material transfer mechanism 2 4, and the material transfer mechanism 3 5, and also facilitates the sequential loading of multiple test stations.

[0036] Embodiment 2

[0037] like Figure 5 As shown, the structure of this embodiment is basically the same as that of the first embodiment, and the difference lies in that: in this embodiment, the testing mechanism 13 includes a lifting plate 1307 driven by a lifting module 1301 to move up and down, and a motor 1305, a torque sensor 1306 and a spline 1308 are installed on the lifting plate 1307, and the spline 1308 is driven by the motor 1305 to control the forward or reverse rotation of the workpiece 100.

[0038] The testing mechanism 13 also includes a bottom plate 1302 for clamping the workpiece 100, on which a second cylinder 1303 is installed, and the second cylinder 1303 drives the energized connection block 1304 to move so that the energized connection block 1304 is plugged with the workpiece 100. In addition, a sensor is installed inside the bottom plate 1302 to detect whether the workpiece 100 is in place.

[0039] The cylinder 1303 drives the power connection block 1304 to move to plug with the workpiece 100 to realize the power-on operation, and then the lifting module 1301 drives the lifting plate 1307 to drive the spline 1308 to move downward, so that the spline 1308 is plugged with the workpiece 100, and the motor 1305 drives the spline 1308 to control the forward or reverse rotation of the workpiece 100, thereby realizing the functional test of the workpiece 100. The functional test includes conventional functional tests such as current on-off test, voltage test, stall torque, forward pull-in torque, reverse pull-out torque, etc., and its test principle is not repeated here.

[0040] Working principle: When the actuator function test equipment is used, the material transfer mechanism 13 sequentially transfers the workpiece 100 on the stage 6 to the test mechanism 13 in the test area 2 through the sliding cooperation between the material transfer mechanism 13 and the moving track 19. When the material transfer mechanism 13 is unable to transfer the workpiece 100 on the stage 6 in time, the material transfer mechanism 35 transfers the workpiece 100 on the stage 6 to the auxiliary stage 14 on the moving track 210 through the moving track 311, and then the material transfer mechanism 24 transfers the workpiece 100 on the auxiliary stage 14 to the test mechanism 13 in the test area 2 through the cooperation between the material transfer mechanism 24 and the moving track 19.

[0041] It should be noted that, no matter the workpiece 100 is transferred to the test area 2 through the material transfer mechanism 1 3 or the material transfer mechanism 2 4 , the materials need to be loaded in sequence according to the positional relationship of the test mechanism 13 .

[0042] Among them, the test mechanism 13 drives the power connection block 1304 to move to plug with the workpiece 100 through the cylinder 2 1303 to realize the power-on operation, and then drives the lifting plate 1307 through the lifting module 1301 to drive the spline 1308 to move downward, so that the spline 1308 is plugged with the workpiece 100, and drives the spline 1308 through the motor 1305 to control the forward or reverse rotation of the workpiece 100, thereby realizing the functional test of the workpiece 100.

[0043] The material transfer mechanism 3 5 is used to perform stroke compensation on the material transfer mechanism 1 3 to prevent the workpiece 100 from being stranded on the stage 6. The material transfer mechanism 1 3 and the material transfer mechanism 2 4 cooperate with each other to realize sequential loading of multiple test stations, and uninterrupted operation of the loading process is achieved, which can effectively improve the test efficiency.

[0044] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
