[0027] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present utility model will be described below in conjunction with the drawings.

[0028] As Figure 1As shown in the figure, a vacuum suction cup fatigue testing machine includes a frame 1 and a horizontal moving mechanism 100 arranged on the frame 1. The horizontal slider 101 of the horizontal moving mechanism 100 is connected to a vertical lifting mechanism 200. The lower end of the vertical lifting mechanism 200 can fix a vacuum suction cup 00. The vacuum suction cup 00 is connected to a vacuum generator 01 to be tested through an air pipe (not shown in the figure). A counter for counting the number of tests of the vacuum suction cup 00 is arranged on the vertical lifting mechanism 200. The horizontal moving mechanism 100, the vertical lifting mechanism 200, and the counter are all connected to a controller 3. During application, the vacuum generator 01 to be tested is connected to the vacuum suction cup 00 through an air pipe. The vacuum generator 01 is started to use the vacuum suction cup 00 to adsorb products. The horizontal moving mechanism 100 and the vertical lifting mechanism 200 are started to simulate reciprocating handling actions. At the same time, the vacuum suction cup 00 follows to perform suction and release of products actions, and several tests are carried out to test the fatigue life of the vacuum suction cup.

[0029] As a preferred structure, as Figure 1 shown in the figure, both the horizontal moving mechanism 100 and the vertical lifting mechanism 200 are arranged in a cabinet 4. A control cabinet 5 is arranged on the side of the cabinet 4. The controller 3 is arranged in the control cabinet 5. An opening for the air pipe to pass through is arranged at the bottom of the partition between the cabinet 4 and the control cabinet 5. Among them, heat dissipation holes are arranged at the top of the control cabinet, and a fan corresponding to the heat dissipation holes is arranged inside. Adopting this structure can effectively protect the horizontal moving mechanism 100, the vertical lifting mechanism 200, and the controller 3, and avoid being affected by external pollution and affecting their service performance.

[0030] During specific design, as Figure 3 shown in the figure, a pressure gauge 6 and a flowmeter 7 are arranged on the air pipe. The counter, the pressure gauge 6, and the flowmeter 7 are all connected to the controller 3. The pressure gauge 6 and the flowmeter 7 are arranged in the control cabinet 5. A control panel 8, control buttons 9, and a connector 10 for connecting the vacuum generator 01 are arranged on the front door panel of the control cabinet 5. The control panel 8 is used to display the number of tests, the air pressure, and the air flow rate of the vacuum suction cup 00. Among them, the control panel 8 can adopt a touch screen. After setting parameters on the control panel 8, the horizontal moving mechanism 100 and the vertical lifting mechanism 200 perform reciprocating movements according to the motion program built in the control panel 8, and the vacuum suction cup 00 follows to perform suction and release of products actions, and the fatigue life of the vacuum suction cup 00 can be tested. At the same time, the performance of the vacuum generator 01 can also be tested through the pressure gauge 6 and the flowmeter 7.

[0031] As Figure 4 shown in the figure, the vacuum generator 01 mainly includes an integrated vacuum generator 011 and a mechanical vacuum generator 012, and different vacuum generators can be replaced according to the test requirements.

[0032] In a specific embodiment of the present invention, asFigure 2 As shown, the frame 1 is a gantry frame. The horizontal movement mechanism 100 includes a horizontal motor 102, a horizontal lead screw, a horizontal slider 101, and a horizontal slide rail 103. The horizontal motor 101 and the horizontal lead screw are both arranged on the cross beam 2 of the frame 1. The output shaft of the horizontal motor 102 is connected to one end of the horizontal lead screw. The inner side of the horizontal slider 101 is in threaded cooperation with the horizontal lead screw. The outer side of the horizontal slider 101 is connected to the vertical lifting mechanism 200 and is in sliding cooperation with the horizontal slide rail 103. Among them, the vertical lifting mechanism 200 includes a mounting frame 201, a vertical motor 202, a vertical lead screw, a vertical slide rail 203, and a vertical slider 204. The mounting frame 201 is connected to the horizontal slider 101. The vertical motor 202 is arranged on the top of the mounting frame 201. The vertical lead screw is arranged inside the mounting frame 201. The vertical slide rail 203 is arranged on the front side of the mounting frame 201. The vertical motor 202 is connected to the upper end of the vertical lead screw. The inner side of the vertical slider 204 is in threaded cooperation with the vertical lead screw. The outer side of the vertical slider 204 is in sliding cooperation with the vertical slide rail 203, and the lower end of the vertical slider 204 can fix the vacuum chuck 00. By driving the horizontal lead screw to rotate with the horizontal motor, the horizontal lead screw drives the horizontal slider and the vertical lifting mechanism 200 to move horizontally along the horizontal slide rail. The vertical motor drives the vertical lead screw to rotate, and then the vertical lead screw drives the vertical slider 204 and the vacuum chuck to move up and down. The combination of these two movements can obtain the movement trajectory of the vacuum chuck, and can simulate the handling action of the vacuum chuck adsorbing products during the actual working process, so as to test the wear of the vacuum chuck rubber head, and detect the failure rate and service life of the vacuum generator after long-term use.

[0033] During specific production, as Figure 2 shown, the outer side of the vertical slider 204 is connected to an L-shaped mounting plate 205. The long side part of the mounting plate 205 is connected to the vertical slider 204. The short side part of the mounting plate 205 is provided with mounting holes 206 for cooperating with the connection bolts at the top of the vacuum chuck 00. Among them, the mounting holes 206 are arranged in parallel for cooperating with the connection bolts on vacuum chucks 00 of different specifications.

[0034] During specific design, as Figure 3 shown, the horizontal motor 102 and the vertical motor 202 are respectively connected to the servo driver 11 in the cabinet 4. Photoelectric switches 12 are arranged on the sides of the horizontal slider 101 and the vertical slider 203 for sensing the strokes of the horizontal slider 101 and the vertical slider 203.

[0035] To further optimize the above technical solution, as Figure 1As shown in the figure, a switchable cabinet door 13 is provided on the front side of the cabinet 4. A transparent observation window 14 is provided on the cabinet door 13, which is convenient for observing the test process, recording abnormal shutdowns and the number of drops of the adsorbed products during handling; a storage cabinet 15 is provided at the bottom of the cabinet 4 and the control cabinet 5. The tabletop width of the storage cabinet 15 is greater than that of the cabinet 4 and the control cabinet 5. The front tabletop of the storage cabinet 15 can place the vacuum generator 01 to be tested, which is convenient for replacing the integrated vacuum generator 011 or the mechanical vacuum generator 012 at any time.

[0036] During specific application, roller wheels 16 are provided at the four corners of the bottom of the storage cabinet 15, and two roller wheels at one end are brake wheels 17. The use of roller wheels facilitates moving the device to any working location. When the device is in place, it is fixed using the brake wheels to prevent movement during the test.

[0037] In summary, the present utility model has the advantages of simple and compact structure, flexible and convenient use. The vacuum generator to be tested is connected to the vacuum suction cup through an air pipe. The vacuum suction cup is used to adsorb the product, and under the drive of the horizontal moving mechanism and the vertical elevator, it simulates the reciprocating handling action. The vacuum suction cup follows to perform the actions of sucking and releasing the product, thereby simulating the wear life of the rubber head of the vacuum suction cup in the actual use environment; and the failure rate and service life of the vacuum suction cup during long-term use are detected through a pressure gauge and a flow meter.
