[0039] Referring to Figure 1 , a valve detection machine includes: a machine table 100, a feeding mechanism 200, a positioning mechanism 600, a gas transmission mechanism 500, a gas blocking mechanism 800, a discharging mechanism 900, and a material transfer mechanism 300. A workbench 700 is arranged on the machine table 100; the feeding mechanism 200 is arranged on the machine table 100; the material transfer mechanism 300 is arranged on the machine table 100. The material transfer mechanism 300 includes a tooling fixture 340, and the tooling fixture 340 can receive the valve from the feeding mechanism 200 and drive the valve to move; the positioning mechanism 600 is arranged on the machine table 100, and the positioning mechanism 600 includes a rotatable fixed component 630, and the fixed component 630 can fix the valve; the gas transmission mechanism 500 is arranged on the machine table 100, and the gas transmission mechanism 500 includes a gas transmission pipe 550, and the gas transmission pipe 550 can supply gas to the valve, and the gas transmission pipe 550 is connected to a detection instrument 400; the gas blocking mechanism 800 is arranged on the machine table 100, and the gas blocking mechanism 800 includes a plug 870, and the plug 870 can block the air outlet of the valve; the discharging mechanism 900 is arranged on the machine table 100.

[0040] After the feeding mechanism 200 feeds the material, the material transfer mechanism 300 will transport the valve to be tested to the workbench 700. Subsequently, the positioning mechanism 600 drives the fixed component 630 to move close to the workbench 700, and clamps the valve core of the valve to be tested through the fixed component 630. The gas transmission mechanism 500 drives the gas transmission pipe 550 to move close to the workbench 700, so that the gas transmission pipe 550 can be connected to the air inlet of the valve to be tested. At the same time, the gas blocking mechanism 800 drives the plug 870 to move to block the air outlet of the valve to be tested. Subsequently, the gas transmission pipe 550 supplies gas to the valve to be tested, and the fixed component 630 drives the valve stem to rotate, so that the airtightness or flow rate and other values of the valve to be tested can be detected by using the detection instrument 400 while supplying gas. After the detection, the gas transmission pipe 550 and the plug 870 move away from the workbench 700, and the material transfer mechanism 300 drives the valve to be tested to move to the discharging mechanism 900 for discharging operation. The material transfer mechanism 300 drives the valve to be tested to move between the feeding mechanism 200, the workbench 700, and the discharging mechanism 900, and the combined action of the positioning mechanism 600, the gas transmission mechanism 500, and the gas blocking mechanism 800 can make the valve to be tested be automatically fed, detected, and discharged. The automatic operation not only has the advantage of high efficiency, but also can effectively save manpower and material resources.

[0041] Specifically, the fixed component 630 is a cylinder gripper.

[0042] In some embodiments, referring toFigure 2 The feeding mechanism 200 includes a feeding track 250. A linear vibrator driver 270 is provided on the feeding track 250. A picking component 230 is provided at the end of the feeding track 250. The tooling fixture 340 can move close to the picking component 230. After the linear vibrator driver 270 is started, the valve to be tested will move to the end of the feeding track 250 through vibration. Then, the picking component 230 picks up a single valve to be tested on the end of the feeding track 250, so as to facilitate the tooling fixture 340 to clamp a single workpiece. Through the combined action of the linear vibrator driver 270 and the picking component 230, the valve to be tested can be fully automatically fed, and the individual valves to be tested can be separated, thus facilitating the transfer component to pick up a single valve to be tested.

[0043] Specifically, a chute 255 is provided on the feeding track 250, and the valve to be tested is slidably installed in the chute 255.

[0044] Specifically, the picking component 230 includes a first slider and a first slide rail. The first slider is connected with a first picking cylinder 233. A second picking cylinder 235 is provided on the first slider. The second picking cylinder 235 is connected with a picking jaw 237. Further, the first slider moves in a direction close to or away from the workbench 700, and the picking jaw 237 moves in a direction close to or away from the feeding track 250.

[0045] In some embodiments, referring to Figure 3 , a material blocking component 290 is provided at one end of the feeding track 250 close to the picking component 230. The material blocking component 290 can block the material before or after the picking component 230 picks up the material, so as to prevent the workpiece on the feeding track 250 from sliding out of the feeding track 250 at this time.

[0046] Specifically, the material blocking component 290 includes a material blocking cylinder 291, and the material blocking cylinder 291 is installed above the feeding track 250. The material blocking cylinder 291 is connected with a material blocking block 295, and the material blocking cylinder 291 can drive the material blocking block 295 to move into the chute 255 and block the valve to be tested.

[0047] In some embodiments, referring to Figure 4 and Figure 5 , the positioning mechanism 600 includes a displacement component 610 and a rotation component 620. The rotation component 620 is provided on the displacement component 610. The displacement component 610 can drive the rotation component 620 to move close to the workbench 700. The rotation component 620 is connected with a fixing component 630 and can drive the fixing component 630 to rotate. After the displacement component 610 drives the rotation component 620 to move close to the workbench 700, the fixing component 630 can clamp the valve stem. When the air pipe 550 supplies air to the valve to be tested, the rotation component 620 can drive the valve stem to rotate, so as to directly test the flow rate and other values of the valve to be tested.

[0048] Specifically, the displacement assembly 610 includes a first motor, the rotation assembly 620 includes a servo motor, the first motor is connected to the servo motor through a second lead screw pair, and the servo motor is connected to the fixed assembly 630. Of course, the displacement assembly 610 and the rotation assembly 620 can also be composed of other components, and the specific implementation can be adjusted according to the actual situation, which is not limited here.

[0049] In some embodiments, referring to Figure 4 , the gas transmission mechanism 500 includes a mounting seat 505 located above the workbench 700. The mounting seat 505 is connected with a lifting cylinder 510 for driving its lifting, and the gas transmission pipe 550 is arranged on the mounting seat 505. After the lifting cylinder 510 drives the mounting seat 505 to descend, the gas transmission pipe 550 can be connected to the valve to be tested, so as to perform gas transmission detection on the valve. After the detection, the lifting cylinder 510 can drive the gas transmission pipe 550 to rise, so as to facilitate the removal of the valve to be tested. By driving the gas transmission pipe 550 through the lifting cylinder 510, the gas transmission pipe 550 can be simply and directly connected to or separated from the valve to be tested, thereby improving the detection efficiency.

[0050] In some embodiments, referring to Figure 4 , a gas valve 520 is arranged on the mounting seat 505, and the gas valve 520 is connected to the gas transmission pipe 550. The gas valve 520 can control the opening and closing of the gas transmission pipe 550 and the gas transmission volume, so as to facilitate the detection of the airtightness and flow rate and other values of the valve to be tested.

[0051] In some embodiments, referring to Figure 4 , the air blocking mechanism 800 includes a telescopic cylinder 850 arranged on the machine table 100. The telescopic cylinder 850 is connected to the plug 870 and can drive it to move closer to the workbench 700. When the telescopic cylinder 850 extends, it can drive the plug 870 to approach the workbench 700 and block the air outlet of the valve to be tested, so as to facilitate the detection of the flow rate or airtightness and other values of the valve to be tested. After the detection is completed, the telescopic cylinder 850 can drive the plug 870 away from the workbench 700, so as to facilitate the removal of the valve to be tested.

[0052] Specifically, two sets of air blocking mechanisms 800 are arranged on the machine table 100. One of the two sets of air blocking mechanisms 800 can be immediately used after the other fails, so as to avoid the problem that the plug 870 is damaged and it takes time and manpower to replace it before the detection can be carried out again.

[0053] In some embodiments, referring to Figure 7 and Figure 8, the blanking mechanism 900 includes a conveyor belt 950, a blanking chute 920, and a discharging chute 940. The blanking chute 920 and the discharging chute 940 are both arranged obliquely downward. The conveyor belt 950 is located below the blanking chute 920. The material transfer mechanism 300 can clamp the workpiece and drive it to move to the blanking chute 920 or the discharging chute 940. After the detection by the material transfer mechanism 300, when the test is qualified, the tested valve is placed in the blanking chute 920. Subsequently, the valve will slide into the conveyor belt 950 within the blanking chute 920 and be driven away by the conveyor belt 950. When the test is unqualified, the material transfer mechanism 300 will place the valve in the discharging chute 940, thereby discharging the unqualified valve. Under the combined action of the discharging chute and the discharging chute 940, the valve to be tested is fully automatically blanked or discharged, so the processing efficiency is greatly improved.

[0054] Specifically, there are two blanking ports 930 provided on the machine table 100. The two blanking ports 930 are respectively communicated with the discharging chute 940 and the blanking chute 920. A control button 910 is provided between the two blanking ports 930. The user can select, according to the control button 910, for the material transfer mechanism 300 to place the workpiece in one of the two blanking ports 930. The control button 910 gives the user the option of discharging and blanking, so that the user can judge by himself whether the tested valve is qualified.

[0055] It can be expected that the material transfer mechanism 300 can also be electrically connected to the test instrument through a judgment circuit (not shown in the figure), so that the material transfer mechanism 300 automatically places the valve in the discharging chute 940 or the blanking chute 920 through the judgment circuit. The specific processing method can be adjusted accordingly according to actual needs and is not limited here.

[0056] In some embodiments, referring to Figure 6 , the material transfer mechanism 300 includes a material transfer track 370, and a support base 310 is provided on the material transfer track 370; a first material transfer component 320 and a second material transfer component 330 are provided on the support base 310.

The material transfer track 370, the first material transfer component 320, and the second material transfer component 330 can cooperate to drive the tooling fixture 340 to perform three-axis movement. Driven by the material transfer track 370, the tooling fixture 340 can reciprocate between the loading mechanism 200, the workbench 700, and the blanking mechanism 900, so as to realize the loading, testing, and blanking of the valve to be tested. The first material transfer component 320 and the second material transfer component 330 can drive the tooling fixture 340 to clamp the valve to be tested from the loading mechanism 200, the workbench 700, or the blanking mechanism 900, so as to perform the next operation. The tooling fixture 340 can perform three-axis movement, so it can simply and directly move to each mechanism to clamp or place, thus ensuring smooth material transfer.

[0057] Specifically, the first material transfer component 320 includes a first cylinder, and the second material transfer component 330 includes a second cylinder. The first cylinder is disposed on the support base 310 and connected to a support plate 335. The second cylinder is disposed on the support plate 335 and connected to the tooling fixture 340. The telescopic directions of the first cylinder and the second cylinder and the direction of the material transfer track 370 are orthogonal to each other in pairs. Of course, the first material transfer component 320 and the second material transfer component 330 may also be composed of other components, and the specific implementation manner can be adjusted accordingly according to the actual situation, which is not limited herein.

[0058] In some embodiments, referring to Figure 1 , a material transfer driving component 375 is disposed on the material transfer track 370. The material transfer driving component 375 is connected to the support base 310 and can drive it to reciprocate on the material transfer track 370.

[0059] Specifically, the material transfer component includes a material transfer motor, and the material transfer motor is connected to the support base 310 through a first screw pair. Of course, the material transfer component may also be composed of other components, such as a cylinder, etc., and the specific implementation manner can be adjusted accordingly according to the actual situation, which is not limited herein.

[0060] In some embodiments, an induction mechanism is disposed at some or all of the workbench 700, the feeding mechanism 200, and the positioning mechanism 600. The induction mechanism can detect numerical values such as the length dimension of the valve tool, the length of the screw, etc., or whether the valve tool lacks small accessories, is misassembled, etc., so as to improve the yield rate of the valve tools after detection.

[0061] Specifically, the induction mechanism includes a second probe 750 disposed at the workbench 700. The second probe 750 can detect whether the valve tool on the workbench 700 is correctly installed, so as to ensure the stable progress of the detection operation on the workbench 700.

[0062] Specifically, the induction mechanism includes a first probe 238 disposed at the feeding mechanism 200. The induction mechanism can not only detect whether the feeding mechanism 200 accurately grasps the valve tool, but also detect whether components such as screws on the valve tool are missing and whether the assembly is accurate, etc., so as to improve the yield rate of the valve tools.

[0063] Further, the induction mechanism includes at least four first probes 238, and the four first probes 238 respectively correspond to the air inlet, the air outlet of the valve tool, and at least two screw positions.

[0064] Specifically, the induction mechanism may be a sensor for sensing distance such as an infrared sensor or a laser sensor, or a microswitch, etc., and the specific implementation manner can be adjusted accordingly according to the actual situation, which is not limited herein.

[0065] In some embodiments, referring to Figure 4 , a sealing joint 555 is provided at the end of the gas pipeline 550. When the gas pipeline 550 is connected to the valve to be tested and supplies gas, the sealing joint 555 ensures that the air flow does not leak from the gap between the gas pipeline 550 and the valve to be tested, thereby guaranteeing the accuracy of the test.

[0066] In some embodiments, an air tank 130 is provided at the lower part of the machine platform 100. The air tank 130 is connected to the cylinders on each mechanism and can supply gas to them.

[0067] Specifically, the test instrument includes a airtightness tester, a flowmeter, etc.
