For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0037] Such as Figure 1 And Figure 6As shown in the figure, the pressurized test mechanism 100 provided by the embodiment of the present invention is adapted to the supporting mechanism 200. The supporting mechanism 200 is used to support the carrier 300 loaded with a plurality of test pieces 700. The pressurized test mechanism 100 is disposed opposite to the supporting mechanism 200, and the carrier 300 is located between the pressurized test mechanism 100 and the supporting mechanism 200. Among them, the carrier 300 can carry a plurality of test pieces 700 at a time, so that a plurality of test pieces 700 are laid flat between the pressurized test mechanism 100 and the supporting mechanism 200.

[0038] The pressurized test mechanism 100 includes: a pressurizing driving device 110, a mounting disk 120, and a plurality of force measuring execution devices 130; the pressurizing driving device 110 is in transmission connection with the mounting disk 120, and the plurality of force measuring execution devices 130 are respectively connected to the mounting disk 120; when the pressurizing driving device 110 drives the mounting disk 120 to approach the supporting mechanism 200, the plurality of force measuring execution devices 130 press the plurality of test pieces 700 one by one.

[0039] Specifically, the plurality of force measuring execution devices 130 are respectively connected to the mounting disk 120, and any one of the force measuring execution devices 130 can be telescopically adjusted relative to the mounting disk 120, so as to adjust the flatness of the test ends of the plurality of force measuring execution devices 130 relative to the reference plane, so that the plurality of force measuring execution devices 130 can simultaneously abut against the corresponding test pieces 700.

[0040] It should be noted that the pressurizing driving device 110 can adopt a telescopic cylinder driven by hydraulic pressure or air pressure, or a servo motor can be used to drive the lead screw to rotate. The lead screw drives the lifting slider cooperating with it to lift and lower, and the mounting disk 120 is connected through the lifting slider to achieve lifting transmission.

[0041] As Figure 1 、 Figure 2 and Figure 6 shown, in the embodiment of the present invention, the force measuring execution device 130 includes: a pressure sensor 131, a telescopic arm column 132, a first elastic member 133, and a pressing head 134; the pressure sensor 131 is connected to the mounting disk 120, one end of the telescopic arm column 132 is connected to the pressure sensor 131, and the other end of the telescopic arm column 132 is connected to the pressing head 134; one end of the first elastic member 133 is connected to the end of the telescopic arm column 132 far from the pressing head 134, and the other end of the first elastic member 133 is connected to the end of the telescopic arm column 132 close to the pressing head 134.

[0042] Among them, the telescopic arm column 132 realizes axial telescoping in a split structure or a nested manner, thereby changing the distance between the indenter 134 and the pressure sensor 131. In addition, the telescopic arm column 132 tends to elongate by the support of the first elastic member 133. When the indenter 134 applies pressure to the test piece 700, the telescopic arm column 132 overcomes the elastic force of the first elastic member 133 and is compressed. By the elastic telescoping of each of the multiple force measuring actuators 130, the requirement for the position consistency of the multiple force measuring actuators 130 installed on the mounting plate 120 is reduced. The flatness of the positions of the test ends of the multiple indenters 134 can also be ensured by the separate elastic telescoping of the multiple force measuring actuators 130, thereby ensuring that each of the multiple indenters 134 can tightly press the corresponding test piece 700 during testing.

[0043] Further, a threaded adjusting member 135 is installed on the telescopic arm column 132. The threaded adjusting member 135 presses the first elastic member 133 along the extending direction of the telescopic arm column 132 for adjusting the compression amount of the first elastic member 133.

[0044] Among them, the threaded adjusting member 135 can adopt a nut fitted on the telescopic arm column 132; it can also adopt a bushing sleeved on the telescopic arm column 132, and a set screw abutting against the telescopic arm column 132 is installed on the bushing. The bushing can slide axially along the telescopic arm column 132, and the position of the bushing can be locked by tightening the set screw. By pressing the first elastic member 133 along the extending direction of the telescopic arm column 132, the initial elastic force of the first elastic member 133 can be adjusted, and thus the initial states of the multiple force measuring actuators 130 can be debugged.

[0045] In an alternative embodiment, the pressure sensor 131 and the arm column 132 are connected by a universal joint. The universal joint is used to realize the free yaw of the arm column 132 relative to the pressure sensor 131, thereby alleviating the problem of inaccurate pressure measurement caused by the installation skew of the arm column 132.

[0046] Further, the pressurizing test mechanism 100 further includes a mounting seat 140. The mounting plate 120 is slidably fitted on the mounting seat 140 along the extending direction of the telescopic arm column 132; a positioning sleeve 136 is installed between the telescopic arm column 132 and the indenter 134. The mounting seat 140 is provided with a guiding hole adapted to the positioning sleeve 136. The positioning sleeve 136 can slide along the guiding hole on the mounting seat 140, thereby ensuring that the indenter 134 tightly presses the corresponding test piece 700 along the axis of the guiding hole. Under the condition that the positioning sleeve 136 is fitted in the guiding hole and the pressure sensor 131 and the arm column 132 are connected by a universal joint, the pressure detected by the pressure sensor 131 is more accurate.

[0047] Such as Figure 6As shown in the figure, the automated testing device provided by the embodiment of the present invention includes: a streamline mechanism 400, and the pressurization testing mechanism 100, the supporting mechanism 200, and the carrier 300 described in the above embodiment; the streamline mechanism 400 is used to convey the carrier 300 and transfer the carrier 300 to the downstream station between the pressurization testing mechanism 100 and the supporting mechanism 200.

[0048] Among them, the streamline mechanism 400 can adopt two parallel conveyor belt mechanisms to convey the carrier 300, and the supporting mechanism 200 can pass through from bottom to top between the two parallel conveyor belt mechanisms, so as to lift the carrier 300 off the streamline mechanism 400.

[0049] The testing process may include: a jacking step, in which the supporting mechanism 200 lifts the carrier 300 and separates the carrier 300 from the streamline mechanism 400; a pressing step, in which the pressurization driving device 110 drives the mounting plate 120 to descend, and makes the plurality of force measuring execution devices 130 respectively press the corresponding measured parts 700 until the preset pressure is reached to complete the test; after the test, the pressurization driving device 110 drives the mounting plate 120 to rise, the plurality of force measuring execution devices 130 respectively separate from the measured parts 700, the supporting mechanism 200 descends, and the carrier 300 falls back onto the streamline mechanism 400. Subsequently, the streamline mechanism 400 can convey the tested carrier 300 to the downstream station, and convey the carrier 300 loaded with the micro-test measured parts 700 between the supporting mechanism 200 and the pressurization driving device 110, so as to repeat the above test steps to realize continuous detection.

[0050] As Figure 3 and Figure 6 shown in the figure, in the embodiment of the present invention, the supporting mechanism 200 is provided with positioning pins 201 adapted to the carrier 300, and the supporting mechanism 200 is installed with an adsorption component 202 for adsorbing the measured part 700. By matching the positioning pins 201 with the corresponding hole positions on the carrier 300, it can be ensured that the supporting mechanism 200 is accurately positioned relative to the carrier 300. In addition, the adsorption component 202 can act on the measured part 700 through the slot holes on the carrier 300, and then the measured part 700 can be adsorbed and fixed.

[0051] See Figure 5 and Figure 6 , in an alternative embodiment, the pressurization testing mechanism 100 is slidably fitted to the clamping mechanism 500 along the pressure application direction of the pressurization driving device 110; the end face of the pressurization testing mechanism 100 facing away from the carrier 300 abuts against the clamping mechanism 500.

[0052] On the one hand, the pressure testing mechanism 100 can be raised and lowered and slid relative to the locking mechanism 500. On the other hand, when the pressure testing mechanism 100 applies pressure to the test piece 700, the pressure testing mechanism 100 rises relative to the test piece 700 and makes the pressure testing mechanism 100 abut against the limiting portion on the locking mechanism 500. When the locking mechanism 500 limits the rise of the pressure testing mechanism 100, the pressure testing mechanism 100 can further realize pressure loading on the test piece 700.

[0053] In an optional embodiment, the positioning mechanism 500 includes: a top frame 510, a lifting drive 520 and a positioning member 530; the lifting drive 520 is installed on the top frame 510, and the lifting drive 520 is connected to the positioning member 530 by transmission; the positioning member 530 is used to abut the pressurized test mechanism 100. The lifting drive 520 can adjust the lifting and lowering of the positioning member 530 relative to the top frame 510, and then the distance between the positioning member 530 and the corresponding part on the pressurized test mechanism 100 in the initial state can be adjusted. When the pressurized test mechanism 100 presses the test piece 700 and rises in the reverse direction to abut against the positioning member 530, the positioning member 530 presses the pressurized test mechanism 100, and then the pressurized test mechanism 100 can further pressurize the test piece 700.

[0054] See also Figure 4 At least one of the pressurized test mechanism 100 and the supporting mechanism 200 is detachably connected to a quick release mechanism 600 , and the quick release mechanism 600 has an electrical adapter for connecting to a test piece 700 .

[0055] Among them, the quick-release mechanism 600 is configured to connect the circuit connectors and air circuit connectors of the test piece 700. When testing the test pieces 700 of different specifications and models, the corresponding pressurized test mechanism 100 and the supporting mechanism 200 can be replaced, and the electrical adapter does not need to be rearranged and assembled. Therefore, the test pieces 700 of different specifications and models can be quickly assembled, which has better versatility and lower modification costs.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
