[0002] The engine control valve is a critical component of the engine's fuel system, its function being to precisely control fuel injection to ensure the engine's normal operation. After manufacturing, the engine control valve needs to be inspected to determine its quality. Current AOI (Automated Optical Inspection) methods typically involve feeding the product onto an inspection platform via a loading mechanism, where vision inspection components around the platform perform the inspection. However, because the inspection requires capturing images of the holes on the control valve's surface, these vision inspection components cannot capture images of the interior of the holes, making inspection difficult.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0040] <Example 1> like Figures 1 to 4 As shown, this embodiment provides an engine control valve testing device for testing an engine control valve 10 (hereinafter referred to as the product). It includes a feeding assembly 100, a testing assembly 200, and a discharging assembly 300. The feeding assembly 100 supplies the product 10. In this embodiment, the product is an engine control valve. The product 10 is generally cylindrical, having an upper plane 101, a lower plane 102, and a circumferential surface 103 disposed between the upper and lower planes. The upper plane 101 has an upper hole 104, and the circumferential surface 103 has three side holes 105. The feeding assembly 100 supplies the product 10 from the feed belt 1 of the upstream equipment to the testing assembly 200 for testing. The testing assembly 200 is located downstream of the feeding assembly 100 and is used to inspect the appearance of the upper and lower planes, the circumferential surface, and the holes of the product 10 to determine whether the control valve is of acceptable quality. The detection assembly 200 includes a rotating platform 250 and first to fourth detection modules sequentially arranged around the rotating platform, namely, a first detection module 210, a second detection module 220, a third detection module 230, and a fourth detection module 240. The rotating platform 250 is an indexing plate driven by a motor to rotate 360°. The rotating platform 250 has several bases 251 for placing the product 10 to be tested. In this embodiment, six bases 251 are provided, evenly spaced on the rotating platform 250. The first detection module 210 is located downstream of the loading position 252 of the rotating platform 250 and is used to detect the upper surface 101 of the product. The second detection module 220 detects the side holes 105 of the product. The second detection module includes a first endoscope component 221 and a second endoscope component 222. The first and second endoscope components are respectively arranged corresponding to the top and side holes of the product. The side holes are side holes 105, and the top holes are top holes 104. The third detection module 230 detects the circumferential surface 103 of the product, and the fourth detection module 240 detects the bottom surface, i.e., the lower plane 102, of the product. The unloading assembly 300 is disposed on the side of the rotating platform 250 and is used to acquire the product from the unloading position 257 of the rotating platform 250. Through the above technical solution, the detection assembly 200 can detect each surface of the product 10, thereby achieving a comprehensive inspection of its appearance.

[0041] Furthermore, the feeding assembly 100 includes a robotic arm 110 and a receiving bin 120. The receiving bin 120 is located on one side of the feeding belt 1, and the product 10 moves towards the feeding assembly via the feeding belt 1. The robotic arm 110 is positioned between the receiving bin 120 and the rotating platform 250, covering both the feeding belt 1 and the rotating platform 250, enabling the robotic arm 110 to move onto the feeding belt 1 and retrieve the product 10. The robotic arm 110 first places the product at the position of the first vision inspection assembly 130. The first vision inspection assembly 130 is used to perform dimensional inspection on the product 10 on the feeding belt 1. Defective products are placed in the receiving bin 120, and qualified products are placed at the loading position 252 of the rotating platform 250. The vision inspection assembly uses a conventional vision device, which is connected to the control system and is used to analyze and process images to obtain results. Six bases 251 are respectively located at the loading position 252, the first detection position 253, the second detection position 254, the third detection position 255, the fourth detection position 256, and the unloading position 257. The first, second, and fourth detection positions are equipped with pick-and-place components 400 for placing and removing products 10 into and from the detection module. When product 10 is being detected, it is fed into the detection module via the pick-and-place components 400. After detection, it is removed onto the base via the pick-and-place components 400. Specifically, the pick-and-place component 400 includes a sliding cylinder 410 and a gripper cylinder 420 mounted on the sliding cylinder 410. The gripper cylinder 420 is correspondingly positioned to the base. After the gripper cylinder 420 grips the product on the base, it extends towards the detection module via the sliding cylinder 410, thus moving back and forth between the detection module and the base, enabling rapid product pick-and-place.

[0042] Furthermore, the first detection module 210 includes a first support base 211 and a second visual detection component 212 disposed above the first support base 211. The pick-and-place component 400 of the first detection position 235 picks and places the product between the base 251 and the first support base 211. When the rotating platform rotates, the product at the loading position 252 rotates to the first detection position 253, and the pick-and-place component 400 places the product on the first support base. The pick-and-place component 400 is disposed on a support platform 500 inside the rotating platform 250. The support platform 500 is fixedly disposed, and the rotating platform 250 rotates around the support platform 500.

[0043] Furthermore, the second detection module 220 includes a second support base 223, a first endoscope assembly 221, and a second endoscope assembly 222. The first endoscope assembly 221 is disposed above the second support base 223 and includes a first endoscope element 2211 and a lifting mechanism 2212 connected to the first endoscope element 2211. The first endoscope element 2211 is vertically disposed. The lifting mechanism 2212 can drive the first endoscope element 2211 to extend into the upper hole 104 for detection. The second endoscope assembly 222 is disposed on the side of the second support base 223 and includes a second endoscope element 2221 and a telescopic mechanism 2222 connected to the second endoscope element 2221. The second endoscope element 2221 is horizontally disposed and can be driven to move horizontally by the telescopic mechanism 2222, thereby allowing it to extend into the side hole 105 for detection. The lifting mechanism 2212 and the telescopic mechanism 2222 can be existing linear movement devices such as sliding cylinders or linear modules. The second detection module 220 includes a telescopic part 224, which is controlled to extend and retract by a sliding cylinder. When extended, the telescopic part 224 is aligned with the side hole 105 of the product. A backlight is provided on the telescopic part 224 to ensure sufficient light in the side hole and improve image clarity. The bottom of the second support base 221 is provided with a rotating mechanism 225, which can be a motor. The rotating mechanism 225 drives the second support base 221 to rotate, allowing the three side holes on the side of the product to be sequentially inspected by the second endoscope.

[0044] Furthermore, the third detection module 230 includes a third support base 231, a flipping component 232, and a third visual detection component 233. The flipping component 232 is used to rotate the product 180° so that the upper surface faces down and the lower surface faces up. The flipping component 232 includes a first rotating mechanism 2321 and a driving mechanism 2322 connected to the first rotating mechanism 2321. The driving mechanism 2322 drives the first rotating mechanism 2321 to reciprocate between the third detection position 255 and the third support base 231. Furthermore, the first rotating mechanism 2321 is connected to a height adjustment mechanism 2323, which is connected to the driving mechanism 2322. The driving mechanism 2322 causes the height adjustment mechanism 2323 to move horizontally, and the height adjustment mechanism 2323 drives the first rotating mechanism 2321 to move vertically, thereby adjusting the position of the first rotating mechanism 2321. In this embodiment, the first rotating mechanism 2321 uses a rotary cylinder, which works with grippers to pick up or release the product. The height adjustment mechanism 2323 and the drive mechanism 2322 employ linear motion devices such as sliding cylinders. The first rotation mechanism 2321 rotates after acquiring the product, placing the upper surface 101 of the product on the third support base 231. The third visual inspection component 233 is located on the side of the third support base 231. This technical solution allows the product to be flipped when transferred to the third support base 231, thereby adjusting the product's orientation. A second rotation mechanism 2321 is located below the third support base 231. The second rotation mechanism 2321 drives the product to rotate, enabling the product to rotate around a vertical axis, thus allowing the third visual inspection component 233 to photograph the circumferential surface 103 of the product from the side. After inspection, the product is returned to the base via the flipping component 232 without flipping during return.

[0045] Specifically, the second rotating mechanism 2321 includes a positioning component 2, a driving component 3, and a rotating component 4. The positioning component 2 is disposed in the third support base 231. The driving component 3 includes a shaft 32, a first driving member 31, and a mounting base 33 connected to the shaft 32. The shaft 32 is inserted into the mounting base 33, and the shaft 32 and the mounting base 33 are movably connected along the Y-axis. When the shaft 32 extends, the positioning component 2 inserts into the product end face hole 104 to fix the product. When the shaft 32 retracts, the positioning component 2 releases the product. That is, when the shaft 32 rises, it can drive the positioning component 2 to fix the product 10, thereby maintaining stability during rotation. When the shaft 32 descends, the positioning component 2 releases the product 10, allowing it to be removed. The first driving member 31 is connected to the shaft 32 through a floating component 5. The first driving member 31 drives the shaft 32 to extend and retract axially. The first driving member 31 is a cylinder, and the extension rod of the cylinder is coaxially arranged with the shaft 32 and connected through the floating component 5. In the Y-axis direction, the extension and retraction of the cylinder's telescopic rod 311 can drive the shaft 32 to move synchronously via the floating assembly 5. When the rotating assembly 4 drives the shaft 32 to rotate, the floating assembly 5 prevents the cylinder's telescopic rod and the shaft 32 from rotating synchronously. The floating assembly 5 enables the shaft 32 and the telescopic rod to move synchronously in the axial direction but asynchronously in the rotational direction. The rotating assembly 4 is connected to the mounting base 33, driving the mounting base 33 and the shaft 32 to rotate around the axial direction. In this embodiment, the rotational direction is around the Y-axis, allowing the product 10 to rotate around the Y-axis, facilitating detection by the horizontally oriented third vision inspection assembly 233. In this embodiment, the shaft 32 and the mounting base 33 move synchronously in the rotational direction and move relative to each other in the Y-axis direction, thereby enabling the shaft to rotate and move axially. The shaft 32 can be a splined shaft, and the shaft 32 and the mounting base 33 are fitted with a keyway.

[0046] Specifically, the positioning component 2 includes several grippers 21 arranged circumferentially in the axial direction. The grippers 21 are movably disposed within and protrude from the third support base 231, meaning the holes on the upper surface of the product 10 are fitted onto the grippers 21, supporting the product 10. The inner wall of the grippers 21 contacts the inner support block 321 at the end of the shaft 32 via an inclined conical surface 22. Thus, when the shaft 32 extends upward, it pushes the grippers 21 to expand outward, thereby pressing the product 10; when the shaft 32 moves downward, the grippers 21 are pulled inward by the gravity of the product 10, releasing the product 10. Through this technical solution, the axial movement of the shaft can control the product's positioning, saving lateral space and facilitating control.

[0047] Furthermore, the positioning component 2 includes a ball-head plunger 23, which is disposed on the third support seat 231 and abuts against the gripper 21. The number of ball-head plungers 23 is the same as the number of grippers 21, with each ball-head plunger 23 abutting against one gripper 21. When the gripper 21 expands outward, the ball-head plunger 23 is compressed. When the gripper 21 loses the pressure provided by the shaft, the ball-head plunger 23 provides a restoring force, causing the gripper 21 to retract, which can further increase the retraction speed of the gripper 21 and prevent the product 10 from getting stuck on the gripper 21. The mounting seat 33 is disposed in the bearing seat 34, and a first bearing 35 is provided between the mounting seat 33 and the bearing seat 34, allowing the mounting seat 33 to rotate smoothly.

[0048] Furthermore, the floating assembly 5 includes a floating joint 51 and a connecting seat 52. One end of the floating joint 51 is fixedly connected to the first driving member 31, and the other end abuts against the shaft 32. The floating joint 51 is movably connected to the connecting seat 52, and a second bearing 36 is provided in the connecting seat 52. The shaft 32 is connected to the second bearing 36. When the telescopic rod 311 of the first driving member 31 extends, it drives the floating joint 51 to move upward in the connecting seat 52, thereby pushing the shaft 32 upward. When the telescopic rod 311 retracts, the shaft 32 moves downward. The rotating assembly 4 includes a second driving member 41, which is connected to the mounting seat 33 through a transmission assembly. The second driving member 41 uses a servo motor to provide rotational power to the mounting seat 33. Specifically, the transmission assembly includes a synchronous belt 42, a first pulley 43, and a second pulley 44. The first and second pulleys are respectively sleeved on the rotating shaft of the second driving member 41 and the mounting seat 33, so that the power of the second driving member 41 can be transmitted to the mounting seat 33.

[0049] like Figure 13 As shown, the fourth detection module 240 further includes a fourth support base 241, and a fourth vision detection component 242 is provided above the fourth support base 241. The fourth vision component 242 detects the lower surface 102 of the product. After the product 10 is flipped over by the third detection module 230 so that its lower surface 102 faces upward, it is convenient for the fourth detection module 240 to perform detection.

[0050] Furthermore, a reversing component 260 is provided downstream of the fourth detection module 240. The reversing component 260 flips the product at the unloading position 257, causing the upper and lower planes of the product to be inverted. The unloading position 257 is within the coverage area of ​​the robot arm 110. After the robot arm 110 picks up the product 10, it places it in the designated position. By using a single robot arm to realize both product loading and unloading after inspection, costs can be reduced.

[0051] <Example 2> In this embodiment, the parts that are the same as in Embodiment 1 are given the same reference numerals, and the same text descriptions are omitted.

[0052] like Figures 14 to 22As shown, compared to Embodiment 1, the engine control valve testing equipment provided in this embodiment further includes a material feeding and stacking device for supplying and stacking trays 20. Empty trays 20 are conveyed to the feeding area 30, where a robotic arm picks up the product 10 and places it into the empty tray 20. Once the tray 20 is full, it is conveyed to the tray storage area for stacking. The material feeding and stacking device in this embodiment includes a supply component 6, a transfer component 7, and a stacking component 8. The supply component 6 includes a bracket 61, a support mechanism 62, and a lifting mechanism 63. The bracket 61 has a receiving cavity 611 in which trays 20 are stacked. The receiving cavity 611 is used to receive empty trays, and the trays 20 stacked from top to bottom are placed in the receiving cavity 611 for use. Specifically, the receiving cavity 611 has an inlet 612 and an outlet 613. The inlet 612 is located above the outlet 613. Empty trays 20 are put in from the inlet and output from the outlet. A support mechanism 62 is located on the side of the receiving cavity 611, supporting or detaching part of the trays 20 from the side. When stacking trays for use, they are output one by one from below. When the bottom empty tray 20 is output, the support mechanism 62 supports the second to last tray, allowing the bottom tray to fall downwards for output. The lifting mechanism 63 is located at the bottom of the receiving cavity 611, supporting and driving the trays 20 to move vertically. The lifting mechanism 63 is located below the outlet 613 and can be raised and lowered. When the empty tray 20 is placed into the receiving cavity, it is supported by the lifting mechanism 63. When it is necessary to output the bottom empty tray, the support mechanism 62 supports the second to last tray from the bottom, and then the lifting mechanism descends, with the bottom tray descending with the lifting mechanism onto the transfer assembly for output. Through the above technical solution, empty trays can be released one by one from below, with the trays stacked and released vertically, reducing the lateral space occupied. The transfer assembly 7 includes a first conveying assembly 71, a second conveying assembly 72, and a third conveying assembly 73. The first conveying assembly 71 is located below the receiving cavity 611 and conveys the tray along a first direction X. The second conveying assembly 72 conveys the tray along a second direction Y, which is perpendicular to the first direction X. The third conveying assembly 73 is arranged parallel to the first conveying assembly 71 and corresponds to the stacking assembly 8. An empty tray 20 moves forward along the first direction X via the first conveying assembly 71. A full tray filled with product 10 is conveyed to the third conveying assembly 73 along the second direction Y via the second conveying assembly 72. The third conveying assembly 73 moves the full tray 20 backward along the first direction X to the stacking assembly 8. The movement path of the tray 20 is U-shaped, and the rotational movement path reduces the length of the movement path. The stacking assembly 8 is located on the same side as the supply assembly 6, that is, next to the supply assembly 6. Users can place an empty tray in the supply assembly 6, move it laterally, and then retrieve the full tray after stacking from the partition, improving work efficiency.A partition 63 is provided between the receiving cavity 611 and the unloading area 30. The first conveying component 71 and the third conveying component 73 pass through the partition 63, thereby isolating the robot arm in the unloading area and improving user safety at the receiving cavity position.

[0053] Specifically, the support mechanism 62 includes a first power source 621 and a support block 622 connected to the first power source 621, driving the support block 622 to extend and retract. The first power source 621 can be a cylinder. The support block 622 is correspondingly arranged with the material tray 20. When the support block 622 extends towards the side of the material tray 20, and is in a supporting state, the support block 622 abuts against the side groove 201 of the second-to-last material tray 20b, preventing it from falling. The lifting mechanism 63 includes a second power source 632 and a top plate 631 connected to the second power source 632. The first conveying assembly 71 includes a first conveyor belt 711, and the top plate 631 is located between the first conveyor belts 711. The top plate 631 supports the falling material tray 20a until it lands on the first conveyor belt 711. The top plate 631 has grippers 633 on both sides, driven by a cylinder 634, which can clamp or release the material tray 20a.

[0054] Furthermore, the third conveying assembly 73 includes a third conveyor belt 731 parallel to the first conveyor belt 711, and the second conveying assembly 72 is disposed between the first conveyor belt 711 and the third conveyor belt 731. The second conveying assembly 72 includes a second conveyor belt 721 perpendicular to the first conveyor belt 711, and a lifting mechanism 722. After the lifting mechanism 722 lifts the material tray, it moves from the first conveyor belt 711 to the third conveyor belt 731 via the second conveyor belt 721. In this embodiment, there are two first conveyor belts 711 and two third conveyor belts 731, and two sets of second conveying assemblies 72. One set is disposed between the two first conveyor belts 711, and the other set is disposed between the third conveyor belts 731. The second conveyor belt 721 is perpendicular to the first and third conveyor belts, thereby enabling the conveying direction of the fully loaded material tray 20 to be changed, that is, a 90° turn is achieved from the first conveyor belt 711 to the second conveyor belt 721, and a 90° turn is achieved from the second conveyor belt 721 to the third conveyor belt 731. The second conveyor belt 721 is mounted on the lifting mechanism 722. The lifting mechanism 722 raises the second conveyor belt 721, causing the fully loaded tray 20 to rise and detach from the first conveyor belt 711. The second conveyor belt 721 contacts the tray, causing the tray 20 to pass over the separator 30 between the first and third conveyor components and be received by another set of second conveyor components 72 between the third conveyor belts. Then, the tray 20 is lowered by the lifting mechanism 722, so that it is positioned on the two third conveyor belts.

[0055] Furthermore, the stacking assembly 8 includes a receiving mechanism 81 and a lifting mechanism 82. The receiving mechanism 81 is located at the end of the third conveyor belt 731 and is used to receive the trays 20 from the third conveyor belt 731. The lifting mechanism 82 is located below the receiving mechanism 81 and is used to receive the trays 20 on the receiving mechanism 81. The third conveyor belt 731 transports the trays 20 to the pallets 811 of the receiving mechanism 81. The pallets 811 are mounted on guide rails 812, and the distance between the two pallets 811 on the same guide rail 812 is increased, allowing the trays 20 to fall onto the side plates 821 of the lifting mechanism 82. The lifting mechanism 82 lowers the trays 20 for placement. Lifting and stacking are common technologies and will not be described in detail here. The stacking assembly 8 includes a receiving cart 83, which is located below the lifting mechanism 82. The trays 20 are stacked on the receiving cart, making it convenient for users to pull away the receiving cart and remove the trays.
