[0021] like Figure 2 As shown in the figure, X refers to the X-axis in the coordinate system, Y refers to the Y-axis in the coordinate system, and Z refers to the Z-axis in the coordinate system.

[0022] like Figure 1-2 As shown, the utility model provides a feeding structure for lifting test, including a main frame 1, a test platform 5 installed on the main frame 1, and a lifting carrier module 2, an upper feeding module 3 and a lower feeding module 4 movably installed on the main frame 1, and a workbench 7 is arranged on the upper feeding module 3 and the lower feeding module 4, and the workpiece is placed on the workbench 7. When the upper feeding module 3 is being tested in the equipment, the lower feeding module 4 can normally take and put materials at the loading station of the equipment, and vice versa.

[0023] Specifically, the lifting vehicle module 2 is movably installed on the main frame 1 through the vertical moving module 8 in cooperation with the linear guide rail, that is, the lifting vehicle module 2 can move along the Z axis in the main frame 1.

[0024] The upper feeding module 3 and the lower feeding module 4 are both movably mounted on the main frame 1 through the lateral moving module 9 in cooperation with the linear guide rail, that is, the upper feeding module 3 and the lower feeding module 4 can both move along the Y axis in the main frame 1.

[0025] For details, please refer to Figure 3 In order to avoid interference, the upper feeding module 3 and the lower feeding module 4 are both installed on the lateral moving module 9 and the linear guide rail through a support frame, and the moving groups of the two lateral moving modules 9 and the linear guide rails are installed staggered inside and outside each other, that is, the lateral moving module 9 and the linear guide rail of the upper feeding module 3 are both placed on the inner side of the lateral moving module 9 and the linear guide rail of the lower feeding module 4, or the lateral moving module 9 and the linear guide rail of the lower feeding module 4 are both placed on the inner side of the lateral moving module 9 and the linear guide rail of the upper feeding module 3; at the same time, the support frame on the outer lateral moving module 9 and the linear guide rail is higher than the support frame on the inner lateral moving module 9 and the linear guide rail, so that the two feeding modules can move staggered without interference, which compresses the proportion of the material taking and placing process in the total test cycle, and occupies a small space.

[0026] During testing, the feeding module moves to the top of the lifting carrier module 2 , the vertical moving module 8 is opened, and the lifting carrier module 2 pushes the workbench 7 away from the feeding module, so that the test platform 5 tests the workpiece on the workbench 7 .

[0027] Furthermore, the main frame 1 is covered with a shell 10, and an alarm light 6 is installed on the shell 10. When there is a problem with the test result, the alarm light 6 flashes to alert the staff.

[0028] Specifically, the lateral moving module 9 and the vertical moving module 8 are electric cylinders, electric lead screws or single-axis robots, etc.

[0029] The warning light 6, the test platform 5, the lateral moving module 9 and the vertical moving module 8 are communicatively coupled to the control panel.

[0030] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0031] The working principle of the utility model is:

[0032] First, the product to be tested is placed in the upper feeding module 3 manually or by a robot, the upper feeding module 3 enters the equipment, and the lower feeding module 4 extends out; then the lifting carrier module 2 is raised to start the test, during which the lower feeding module 4 completes the picking and placing of the product to be tested; then the lifting carrier module 2 is lowered, and the product to be tested is placed back on the upper feeding module 3; then the upper feeding module 3 is moved out of the test station, the lower feeding module 4 enters the test station, the lifting carrier module 2 is raised, and the test starts, during which the upper feeding module 3 completes the picking and placing of the product to be tested, the lifting carrier module 2 is lowered, and the product to be tested is placed back on the lower feeding module 4, and then the above operations are repeated continuously.

[0033] The lower feeding module 4 and the upper feeding module 3 utilize the test time without interfering with each other, and merge the process time of taking and placing the products to be tested, which greatly improves the production efficiency and ensures that the space occupied by the equipment is small.

[0034] 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.
