Description

Technical Field

[0001] The present invention relates to the technical field of valves, and more particularly, to a cut-off type water collector testing device. Background Art

[0002] The cut-off type water collector is an important control component of the heating system. Cooperating with a thermostat and an electric heating actuator, it can intelligently adjust and control the flow rate of each branch of the heating system, and then output a comfortable heating temperature. The dimensional accuracy of the cut-off valve core of the water collector directly determines the accuracy of intelligent control. Therefore, the detection of the cut-off type water collector is particularly important.

[0003] Currently, for the cut-off type water collector, a manual detection method is generally adopted, and the testing process is relatively complex:

[0004] First step, the product is fixed by a tooling, the exposed ports are sealed, and gas is introduced into the product to check the overall sealing performance.

[0005] Second step, use manual tools to press the valve stems of each branch in turn, and check the sealing performance of the valve core when the valve stem moves one by one.

[0006] Third step, the product is taken back to the assembly line, the handwheels of each branch are assembled, and the handwheels are tightened. Then the product is placed on the testing table with the exposed ports of the branches in an open state to detect the internal sealing performance of the product. Finally, to avoid the valve core of the product being in a compressed state for a long time, the handwheel of the product is loosened after detection.

[0007] The above manual detection method has at least the following problems:

[0008] A. The steps are cumbersome, the operation is complex, and the efficiency is low;

[0009] B. The method of pressing the valve core with the handwheel to detect the internal seal is not scientific enough. This detection method can only detect whether the valve core can be manually closed, and cannot detect whether the stroke of the valve core and the electric heating actuator match;

[0010] C. There are many detection steps, and the product is turned around many times during the detection process, which is easy to damage the appearance of the product.

[0064] Embodiment

[0065] Please refer to Figure 1 , the cut-off type water collector testing device 1000 provided in this embodiment includes a conveying device 100, a grasping device 200, a frame 300, a fixing device 400, a testing device 500, and a spraying device 600.

[0066] The conveying device 100 is used to convey the cut-off type water collector 2000, and the cut-off type water collector 2000 can be operated in a streamlined manner through the conveying device 100.

[0067] As a reference, the conveying device 100 can adopt a conveyor belt.

[0068] The grasping device 200 is used to grasp the cut-off type water collector 2000 located on the conveying device 100 to the testing station on the frame 300, and the cut-off type water collector 2000 can be grasped from the conveying device 100 to the testing station through the grasping device 200.

[0069] The fixing device 400 is arranged on the frame 300 and is mainly used to fix the cut-off type water collector 2000 located at the test station. The cut-off type water collector 2000 can be stabilized through the fixing device 400.

[0070] The testing device 500 is arranged on the frame 300 and is mainly used to test the fixed cut-off type water collector 2000.

[0071] The spraying device 600 is arranged on the frame 300 and is mainly used to spray the cut-off type water collector 2000 with unqualified test results. That is, the spraying device 600 can spray and identify the unqualified ones.

[0072] As a reference, the spraying device 600 can adopt a nozzle to spray a color mark on the product surface when detecting that the product is unqualified.

[0073] The above-mentioned cut-off type water collector testing equipment 1000 can realize the rapid testing of the cut-off type water collector 2000, greatly improving the detection efficiency.

[0074] Furthermore, in order to facilitate the adaptation to products of different specifications, Figure 1 the cut-off type water collector testing equipment 1000 further includes a baffle 800. The baffle 800 is movably arranged on the conveying device 100 to adapt to cut-off type water collectors 2000 of different specifications. For example, the position of the baffle 800 can be adjusted according to the product size to adapt to products of different specifications.

[0075] Furthermore, the cut-off type water collector testing equipment 1000 further includes a photoelectric sensor 700. The photoelectric sensor 700 is arranged on the conveying device 100. After the photoelectric sensor 700 detects that the cut-off type water collector 2000 has been conveyed in place on the conveying device 100, it outputs a pause signal. In other words, when the product reaches the grasping position, the photoelectric sensor 700 outputs a signal, the conveying device 100 pauses conveying, and at the same time, the grasping device 200 automatically grasps the product and sends the product to the test station.

[0076] Furthermore, the cut-off type water collector testing equipment 1000 further includes an isolation device 900. The grasping device 200 is used to grasp the unqualified cut-off type water collector 2000 to the isolation device 900.

[0077] It can be understood that the conveying device 100 is divided into a feeding area and a qualified area along the traveling direction. The isolation device 900 is located between the feeding area and the qualified area. That is, an isolation area is formed between the feeding area and the qualified area. The product enters from the feeding area, is grasped by the grasping device 200 to the test station for testing. When the product is qualified, it is finally grasped by the grasping device 200 from the test station to the qualified area. When the product is unqualified, the grasping device 200 grasps the product on the test station to the isolation device 900 (i.e., the isolation area).

[0078] Please refer to again Figure 2 The grasping device 200 includes a base body 210, a first moving body 220, a first power source 230, a second power source 240, a second moving body 250, a manipulator 260, and a third power source 270.

[0079] The first power source 230 is arranged on the base body 210 and is used to drive the first moving body 220 to move in the front-back direction. The second power source 240 is arranged on the first moving body 220 and is used to drive the second moving body 250 to move in the left-right direction. The third power source is arranged on the second moving body 250 and is used to drive the manipulator 260 to move in the up-down direction.

[0080] It can be understood that the above-mentioned grasping device 200 can realize the movement in the XYZ directions, so as to conveniently grasp the products on the conveying device 100 to the test station, and grasp the products on the test station to the qualified area or the isolation area.

[0081] Specifically, the first power source 230 includes a first servo motor 231 and a first toothed belt 232. The first servo motor 231 is arranged on the base body 210. The first servo motor 231 is in transmission connection with the first toothed belt 232, and the first toothed belt 232 is in transmission connection with the first moving body 220.

[0082] The second power source includes a second servo motor 241 and a second toothed belt 242. The second servo motor 241 is arranged on the first moving body 220. The second servo motor 241 is in transmission connection with the second toothed belt 242, and the second toothed belt 242 is in transmission connection with the second moving body 250.

[0083] The third power source includes a third servo motor 271 and a rack and pinion mechanism 272. The third servo motor 271 is connected to the manipulator 260 through the rack and pinion mechanism 272.

[0084] In this embodiment, the manipulator 260 includes a cylinder and two grippers driven by the cylinder. The cylinder is installed on the rack of the rack and pinion mechanism 272, and the pinion of the rack and pinion mechanism 272 is installed on the motor shaft of the third servo motor 271.

[0085] Please refer to again Figure 3 The fixing device 400 includes a fourth power source 410, a fifth power source 420, a sixth power source 430, a first sealing block 440, a second sealing block 450, and a plurality of fixing blocks 460.

[0086] A plurality of fixed blocks 460 are distributed in two rows, such that a test station is formed between the two rows; a fourth power source 410 is used to drive the plurality of fixed blocks 460 so that the plurality of fixed blocks 460 clamp the cut-off type water collector 2000 located on the test station. A fifth power source 420 is used to drive the first sealing block 440 to seal or open one end of the main path 2001 of the cut-off type water collector 2000. A sixth power source 430 is used to drive the second sealing block 450 to seal or open the other end of the main path 2001 of the cut-off type water collector 2000.

[0087] Meanwhile, in combination with Figure 3 and Figure 4 , the test device 500 includes a detection chuck 510, a seventh power source 520, an eighth power source 530, a ninth power source 540, and a sealing plate 550.

[0088] The detection chuck 510 includes a sleeve 511 and a core rod 512 movably connected to the sleeve 511. The seventh power source 520 is used to drive the sleeve 511 to be sleeved and fitted on the valve head 2004 of the cut-off type water collector 2000; the eighth power source 530 is used to drive the core rod 512 to actuate the valve stem 2003 of the cut-off type water collector 2000. The ninth power source 540 is used to drive the sealing plate 550 to fit or move away from the port of the branch path 2002 of the cut-off type water collector 2000. Among them, the sealing plate 550 is provided with a vent hole 551 corresponding to the port of the branch path 2002.

[0089] Specifically, the sleeve 511 and the core rod 512 are coaxially arranged, a through hole 5112 is formed in the bottom wall of the sleeve 511, and the core rod 512 is inserted into the through hole 5112. Meanwhile, the number of the ninth power sources 540 is multiple, and the multiple ninth power sources 540 are uniformly and spaced apart in sequence.

[0090] Please refer to Figures 5 to 7 together with Figure 5 , as shown in

[0091] , the product structure diagram of the cut-off type water collector 2000 includes a main path 2001, a branch path 2002, a valve stem 2003, a valve head 2004, a valve core 2006, etc. The part of the valve head 2004 where the valve core 2006 is exposed cooperates with an electric heating actuator to control the movement of the valve stem 2003 and adjust the flow rate of the branch path 2002. Figure 6 As shown in Figure 4 , in the natural state, the valve core 2006 is in an open state, the height of the valve head 2004 is H, the outer diameter of the valve head 2004 is d, the fixed surface 2005 of the valve core 2006 fits with the bottom surface of the detection chuck 510. Specifically, in combination with

[0092] , the bottom surface is the annular surface 5111 of the sleeve 511. Figure 7As shown, under a certain pressing force, generally 20 - 30 N, the valve core 2006 is in the closed state. At this time, the height of the valve head 2004 is H1, and H1 is the dimension that matches the electrothermal actuator when the valve core 2006 is normally closed.

[0093] During the detection, the bottom surface of the sleeve 511 is closely attached to the fixing surface 2005 of the product, which is the reference surface during the test process. Combining Figure 4 , the inner diameter D of the sleeve 511 is slightly larger than the outer diameter d of the valve head 2004 of the product valve core 2006, and is used to detect the dimensions of the valve core 2006 and the valve head 2004. Figure 4 In [reference], the core rod 512 forms a distance L with the bottom surface of the sleeve 511. When the core rod 512 is in the initial state, L is slightly larger than the height H of the valve head 2004. At this time, the valve core 2006 is in the open state; under the control of the eighth power source 530, after the core rod 512 extends, the distance L formed with the bottom surface of the sleeve 511 is equal to the height H1 of the valve head 2004 when the product valve core 2006 is closed, that is, the combination of the core rod 512 and the sleeve 511 is used to detect whether the stroke of the valve core 2006 and the valve stem 2003 meets the standard requirements.

[0094] The following combines Figures 8 to 11 to introduce the test process of the stop - type water collector 2000.

[0095] As Figure 8 shown, when the product is detected, first fix the product, that is, under the driving action of the fourth power source 410, both the upper and lower sides of the product are fixed by the fixing blocks 460, and both ends of the main path 2001 of the product are open.

[0096] As Figure 9 shown, the internal seal detection diagram of the product. Under the driving action of the ninth power source 540, the sealing plate 550 fits the port of the branch path 2002 of the product, and the ventilation hole 551 of the sealing plate 550 corresponds to the product branch path 2002. Under the driving action of the seventh power source 520, the sleeve 511 of the detection chuck 510 fits the fixing surface 2005 of the product, and the eighth power source 530 applies a fixed force N to the core rod 512, and the magnitude of the force is determined by the closing force of the valve core 2006. After the core rod 512 is pressed down, air is introduced into the branch path 2002 through the ventilation hole 551 of the sealing plate 550 to detect the internal sealing of the product.

[0097] As Figure 10 shown, the external seal detection diagram of the product. Under the driving action of the fifth power source 420 and the power source, both ends of the main path 2001 of the product are closed by the first sealing block 440 and the second sealing block 450. The acting force of the core rod 512 is removed, the core rod 512 retracts, the valve core 2006 of the product is in the open state, and air is introduced into the product to check the sealing performance.

[0098] As Figure 11As shown, in the product dynamic seal detection diagram, both the main path 2001 and the branch path 2002 of the product are in a sealed state. Driven by the eighth power source 530, the core rod 512 moves reciprocally, pushing and pressing the product valve stem 2003 and the valve core 2006. When detecting the movement of the valve stem 2003, the product sealing performance is detected.

[0099] Please refer to Figure 12 The test flow chart of the stop type water collector 2000 shown. Only when the product meets the internal seal detection condition, the external seal detection condition, and the dynamic seal detection condition, the product is judged as a qualified product (good product), otherwise the product is judged as an unqualified product (bad product).

[0100] Continuing from the above, the working principle of the stop type water collector test device 1000 provided in this embodiment includes:

[0101] The product is transported through the conveying device 100, automatically grabbed by the manipulator 260, placed on the test station, fixed by the fixing device 400, and the detection chuck 510 is driven by the seventh power source 520 and the eighth power source 530 to detect the sealing performance of the product and the size of the valve core 2006. By controlling the distance between the sleeve 511 of the detection chuck 510 and the core rod 512, the stroke of the valve core 2006 is accurately detected.

[0102] Specifically, after the product is fixed, the seventh power source 520 drives the sleeve 511 of the detection chuck 510 to closely adhere to the fixing surface 2005 at the top of the valve core 2006, and the eighth power source 530 drives the core rod 512 of the detection chuck 510 to extend, pressing against the valve stem 2003, and the end face of the core rod 512 of the detection chuck 510 maintains a constant distance from the fixing surface 2005. This distance is exactly the distance for the valve core 2006 to cooperate with the electric heating actuator, thereby detecting the accuracy of the stroke of the valve core 2006. The inner hole size of the sleeve 511 of the detection chuck 510 is matched with the outer diameter of the valve head 2004 to detect the size of the valve head 2004. After the internal seal detection, the core rod 512 is driven to retract and then extend, repeating several times to detect the sealing performance of the valve core 2006 when the valve stem 2003 moves. After the detection is completed, the manipulator 260 sends the product to the conveyor belt; if a sealing problem is found in the product during the detection process, the spraying device 600 sprays and marks the surface of the product, and the manipulator 260 clamps the product onto the isolation device 900 for isolation and rework.

[0103] The entire detection process is fully automated, liberating human labor. During the product testing process, only one fixation is required to complete multiple-step test verification, while reducing the testing steps and significantly improving the detection efficiency. By matching the distance between the sleeve 511 and the core rod 512 for detection, the stroke dimension of the valve core 2006 can be detected accurately and reliably. Automated detection can operate on the valve stems 2003 of multiple branches 2002 simultaneously, shortening the detection time. Marking and isolating defective products can prevent the outflow of defective products, making it more reliable.

[0104] In summary, the stop-type water collector testing device 1000 provided in this embodiment has at least the following advantages:

[0105] (1) Automated detection improves the detection efficiency and liberates human labor.

[0106] (2) Automated detection enables synchronous detection of multiple branches 2002 and multiple workstations.
