[0079] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0080] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the invention to those skilled in the art.

[0081] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0082] The following is for reference. Figures 1-16 This describes a solenoid valve assembly and testing apparatus according to an embodiment of the present invention. This apparatus can automatically assemble solenoid valves together; for example... Figure 1 As shown, the solenoid valve includes a moving valve core A, a spring B, a stationary valve core C, a sealing ring D, an outer frame E (C-ring), and a plastic part F. The plastic part F has two accommodating cavities with openings facing opposite directions. Each accommodating cavity is equipped with the moving valve core A, spring B, stationary valve core C, sealing ring D, and outer frame E (C-ring). During assembly, the moving valve core A is first placed into the accommodating cavity, followed by the spring B, with one end of the spring B abutting against the moving valve core A. Then, the sealing ring D is fitted onto the stationary valve core C, and the stationary valve core C is then placed into the accommodating cavity, with the other end of the spring B abutting against the stationary valve core C. Finally, the outer frame E is snapped onto the plastic part F. Specifically, one end of the outer frame E is snapped against the opening end face of the accommodating cavity to limit the stationary valve core C and prevent it from detaching from the accommodating cavity, while the other end of the outer frame E is snapped into the slot of the plastic part F.

[0083] Combination Figures 2-16 According to an embodiment of the present invention, an assembly and testing device for a solenoid valve includes: a circulating conveyor line 1 and a plastic part feeding device 2, a first moving valve core feeding device 3, a first spring feeding device 4, a first detection device 5, a first stationary valve core feeding device 6, a first outer frame feeding device 7, a first flipping device 8, a second moving valve core feeding device 9, a second spring feeding device 10, a second detection device 11, a second stationary valve core feeding device 12, a second outer frame feeding device 13, and a testing device 14 arranged around the outer periphery of the circulating conveyor line 1.

[0084] Specifically, the circulating conveyor line 1 is provided with several tooling fixtures 101; the plastic part feeding device 2 is adapted to place the plastic part F on the tooling fixture 101, the plastic part F having a first receiving cavity and a second receiving cavity, both the first receiving cavity and the second receiving cavity having open opening ends with their openings facing opposite directions; the first moving valve core feeding device 3 is adapted to insert the first moving valve core into the first receiving cavity of the plastic part F on the tooling fixture 101; the first spring feeding device 4 is adapted to insert the first spring into the first receiving cavity so that one end of the first spring abuts against the first moving valve core; the first detection device 5 is adapted to detect whether there is a first spring in the first receiving cavity; the first stationary valve core feeding device 6 is adapted to, after fitting a sealing ring onto the first stationary valve core, insert the first stationary valve core into the first receiving cavity so that the other end of the first spring abuts against the first stationary valve core; the first outer frame feeding device 7 is adapted to snap the first outer frame onto the plastic part F and The device includes: a first stationary valve core limiting device; a first flipping device 8 adapted to flip the plastic part F 180° to change the opening orientation of the first and second receiving cavities; a second moving valve core feeding device 9 adapted to feed the second moving valve core into the second receiving cavity of the plastic part F on the tooling 101; a second spring feeding device 10 adapted to feed the second spring into the second receiving cavity so that one end of the second spring abuts against the second moving valve core; a second detection device 11 adapted to detect whether there is a second spring in the second receiving cavity; a second stationary valve core feeding device 12 adapted to feed the second stationary valve core into the second receiving cavity after the sealing ring is fitted on the second stationary valve core so that the other end of the second spring abuts against the second stationary valve core; a second outer frame feeding device 13 adapted to snap the second outer frame onto the plastic part F and limit the second stationary valve core; and a testing device 14 adapted to perform airtightness, air leakage, and pressure resistance tests on the plastic part after the second outer frame is snapped on.

[0085] In other words, the tooling 101 on the circulating conveyor line 1 can position the plastic part F and transport it along the conveying direction to each station for different processing and testing; the arrangement of several tooling 101s allows the assembly of multiple solenoid valves to be carried out simultaneously, greatly improving efficiency; in addition, the aforementioned plastic part feeding device 2, first moving valve core feeding device 3, first spring feeding device 4, first detection device 5, first stationary valve core feeding device 6, first outer frame feeding device 7, first flipping device 8, second moving valve core feeding device 9, second spring feeding device 10, second detection device 11, second stationary valve core feeding device 12, second outer frame feeding device 13 and testing device 14 are arranged sequentially along the conveying direction of the circulating conveyor line 1.

[0086] Therefore, according to the solenoid valve assembly and testing equipment proposed in this invention, the plastic part F (skeleton) of the solenoid valve is sequentially transferred to each station by the tooling 101 on the circulating conveyor line 1 for assembly of each component (moving valve core A, spring B, stationary valve core C, and outer frame E). After the assembly is completed, the plastic part is flipped over, and the other end of the plastic part is used to assemble the components (moving valve core A, spring B, stationary valve core C, and outer frame E), thus achieving fully automated assembly of the solenoid valve. By setting up a first detection device 5 and a second detection device 11, the assembly process can be checked for omissions. By setting up a testing device 14, the solenoid valve can be tested immediately after assembly, improving efficiency, preventing omissions and misassemblies of the solenoid valve, and ensuring quality.

[0087] See Figures 2-4 For the circulating conveyor line 1, the circulating conveyor line 1 may include a guide rail, rollers and a drive structure of a synchronous belt for a motor. The bottom of the tooling 101 is provided with rollers, which roll on the guide rail. The tooling 101 is connected to a synchronous belt, so that the synchronous belt drives the tooling 101 to move.

[0088] In this system, a positioning mechanism 102 is provided at the position of each device on the circulating conveyor line 1 to pause the conveying of the tooling 101. It can be understood that at the position of each device, parts need to be loaded and assembled onto the plastic parts F within the tooling 101, at which time the positioning mechanism 102 needs to pause the conveying of the tooling 101. The positioning mechanism 102 may include a positioning plate 1021, a first swing rod 1022, a rotating rod 1024, a second swing rod 1025, and a cylinder. The positioning plate 1021 is mounted on the tooling 101. One end of the first swing rod 1022 is equipped with a roller, and the other end is pivotally mounted on the rotating rod 1024. The rotating rod 1024 is rotatably mounted on the frame of the circulating conveyor line 1. One end of the second swing rod 1025 is connected to the cylinder, and the other end is pivotally mounted on the rotating rod 1024. Thus, by driving the second swing rod 1025 to swing, the first swing rod 1022 swings, thereby causing the roller to lock onto the positioning plate 1021 to pause the conveying of the tooling 101.

[0089] In addition, several tooling fixtures 101 are arranged at intervals on the circulating conveyor line 1, and the distance between two adjacent tooling fixtures 101 is the same as the distance between two adjacent devices; so that multiple plastic parts F can be processed at different workstations at the same time, improving assembly efficiency.

[0090] For the circulating conveyor line 1, its top view is elliptical to facilitate the arrangement of the various devices.

[0091] Combination Figure 5For the plastic part feeding device 2, the plastic part feeding device 2 includes a storage section 201, a plastic part adsorption component 202, an X-axis moving drive component 203, a Y-axis moving drive component 204, and a Z-axis moving drive component 205. The storage section 201 is suitable for storing pallet stacks, each pallet containing multiple plastic parts F. The plastic part adsorption component 202 is disposed on the moving end of the Z-axis moving drive component 205, the Z-axis moving drive component 205 is disposed on the moving end of the Y-axis moving drive component 204, and the Y-axis moving drive component 204 is disposed on the moving end of the X-axis moving drive component 203 to feed the plastic parts in the pallets into the tooling 101 on the circulating conveyor line 1. The storage section 201 may include full pallet stacks and empty pallet stacks; the plastic part adsorption component 202 feeds the plastic parts F in the pallets under the action of the X / Y / Z-axis moving drive components and places the empty pallets in the empty pallet stack. The X-axis motion drive 203, Y-axis motion drive 204, and Z-axis motion drive 205 can be motor-driven linear module structures.

[0092] Combination Figure 6 The structure and principle of the first moving valve core feeding device 3 and the second moving valve core feeding device 9 are the same. Here, we will take the first moving valve core feeding device 3 as an example for further explanation.

[0093] The moving valve core feeding device 3 includes a first vibratory plate 301, a moving valve core gripper 302, a first drive assembly 303, and a tape feeding section 304. The first vibratory plate 301 is equipped with a moving valve core A and is adapted to move the moving valve core A to its outlet; the tape feeding section 304 has a dust-removing tape 3041, the dust-removing surface of the dust-removing tape 3041 is adapted to contact the moving valve core A to remove dust from the moving valve core A; the first drive assembly 303 is connected to the moving valve core gripper 302 to drive the moving valve core gripper 302 to grip the moving valve core A from the outlet and move the moving valve core A to contact the dust-removing surface of the dust-removing tape 3041 or to move it to the receiving cavity of the plastic part F on the tooling 101 of the circulating conveyor line 1.

[0094] In other words, after the moving valve core gripper 302 picks up the moving valve core A from the discharge port, it can move the moving valve core A to the dust removal surface of the dust removal belt 3041 for dust removal, and then feed it back in. For the moving valve core A, both the top and bottom surfaces usually need to be dusted. Therefore, the first drive assembly 303 can drive the moving valve core A to rotate 180° after dust removal on the top surface, and then dust its bottom surface.

[0095] Therefore, according to the embodiment of the present invention, the moving valve core feeding device 3, by setting the cooperation of the tape feeding part 304 and the first driving component 303, allows the moving valve core gripper 302 to grip the moving valve core A and then move the moving valve core A to the contact dust removal tape 3041 for dust removal. After dust removal, it is then fed into the receiving cavity of the plastic part F on the tooling 101. Thus, when the moving valve core A is fed, the end face of the moving valve core A can be dusted, ensuring the use of the solenoid valve after assembly.

[0096] The first drive assembly 303 includes a first lifting drive 3031, a moving drive 3032, and a rotating drive 3033. The first lifting drive 3031 is disposed at the moving end of the moving drive 3032, and the rotating drive 3033 is disposed on the moving end of the first lifting drive 3031. The moving valve core gripper 302 is disposed on the rotating drive 3033. The rotating drive 3033 is adapted to drive the moving valve core A to rotate 180° to remove dust from both ends of the moving valve core A.

[0097] Understandably, the cooperation of the first lifting drive 3031 and the moving drive 3032 allows the moving valve core gripper 3032 to grip the moving valve core A from the discharge port, move the moving valve core A to contact the dust removal surface of the dust removal belt 3041 for dust removal, or place the dust-removed moving valve core A in the receiving cavity. The cooperation of the rotation drive 3033, the first lifting drive 3031 and the moving drive 3032 can remove dust from both end faces of the moving valve core A.

[0098] Among them, the first lifting drive component 3031 can be a lifting cylinder, the rotary drive component 3033 can be a rotary cylinder, and the moving drive component 3032 can be a rodless cylinder.

[0099] For the first vibratory feeder 301, its discharge port is provided with two opposing movable blocks 3011. The two movable blocks 3011 together form a clamping opening suitable for clamping the moving valve core A, thereby preventing the moving valve core A from falling off the discharge port. Specifically, one end of the two movable blocks 3011 can be hinged to the discharge port. After the two movable blocks 3011 clamp the moving valve core A, the moving valve core gripper 302 clamps and moves the moving valve core A. The moving valve core gripper 302 can clamp the center part of the moving valve core A, so that its two end faces are exposed, which facilitates dust removal operation.

[0100] In addition, the first vibratory plate 301 can be connected to the direct vibration conveying channel to facilitate the vibration discharge of the moving valve core A. The discharge port is set at the port of the direct vibration conveying channel.

[0101] The tape feeding section 304 includes a mounting plate 3042, a reel 3043, a gluing block 3044, and a collecting roller 3045. The mounting plate 3042 is vertically mounted. The reel 3043, the gluing block 3044, and the collecting roller 3045 are all pivotally connected to the mounting plate 3042. The reel 3043 has a dust-removing tape roll. One end of the dust-removing tape 3041 is pulled out from the dust-removing tape roll, passes through the gluing block 3044, and is wound onto the collecting roller 3045. The dust-removing surface of the dust-removing tape 3041 on the gluing block 3044 faces outward to contact the moving valve core A. The collecting roller 3045 can be driven by a motor to wind up the dust-removing tape 3041.

[0102] In this configuration, the dust-removing adhesive tape 3041 on the adhesive block 3044 is positioned with its dust-removing surface facing downwards. Thus, when the moving valve core gripper 302 clamps the moving valve core A, the moving drive member 3032 drives the end face of the moving valve core A to the dust-removing surface of the adhesive tape 3041 on the upper end of the alignment device, and then the first lifting drive member 301 drives the moving valve core A to move to contact the dust-removing surface.

[0103] The tape feeding unit 304 also includes a first tensioning roller 3046 and a second tensioning roller 3047. Both the first tensioning roller 3046 and the second tensioning roller 3047 are arranged above the adhesive conveyor block 3044 to tension the dust-collecting tape 3041 on the adhesive conveyor block 3044. That is to say, the trajectory of the dust-collecting tape 3041 is constructed by the layout of the reel 3043, the first tensioning roller 3046, the adhesive conveyor block 3044, the second tensioning roller 3047, and the collecting roller 3045.

[0104] In addition, the tape feeding unit 304 also includes a second lifting drive 3048, which is connected to the mounting plate 3042 to drive the mounting plate 3042 to move up and down, thereby adjusting the position of the tape feed block 3044. The second lifting drive 3048 can be used to adjust the position of the tape feed block 3044, and can also work with the first lifting drive 3031 to remove dust from the valve core A. The second lifting drive 3048 can be a cylinder structure.

[0105] Furthermore, the moving valve core feeding device may also include a vision detector, which is suitable for detecting and identifying the front and back sides of the moving valve core A on the moving valve core gripper 302. The vision detector and the tape feeder 304 can be mounted on the discharge port and above the moving valve core gripper 302 via support columns.

[0106] Combination Figure 7 and Figure 8 The structure and principle of the first spring feeding device 4 and the second spring feeding device 10 are the same. Here, we will take the first spring feeding device 4 as an example for further explanation.

[0107] The first spring feeding device 4 includes a second vibrating plate 401 and a material distribution assembly; the second vibrating plate 401 is equipped with a spring B and is adapted to move the spring B to its outlet; the material distribution assembly includes a material distribution block 402, an air blowing connector 403 and a discharge channel 404, the discharge channel 404 is movable between a position that aligns with and contacts the opening of the receiving cavity of the plastic part F and a position that leaves the plastic part F, the material distribution block 402 is provided with a groove 4021 adapted to receive the spring B, the material distribution block 402 is movable between a position that makes the groove 4021 communicate with the outlet and a position that communicates with the discharge channel 404, the air blowing connector 403 is disposed above the discharge channel 404 and is adapted to blow the spring B in the groove 4021 into the discharge channel 404 and into the receiving cavity of the plastic part F.

[0108] The material distribution block 402 is moved by a horizontal moving cylinder. The groove 4021 on the side of the material distribution block 402 is provided so that the groove 4021 can communicate with the discharge port or with the discharge channel 404.

[0109] The movement of the discharge channel 404 can be driven by a lifting cylinder. The discharge channel 404 moves up and down and moves between the position of aligning with and contacting the opening of the accommodating cavity of the plastic part F and the position of leaving the plastic part F. In this way, the spring B is directly guided into the accommodating cavity by the discharge channel 404 and its bottom end abuts against the moving valve core A in the accommodating cavity.

[0110] In addition, the second vibratory plate 401 can be connected to the direct vibration conveying channel to facilitate the vibration discharge of spring B. The discharge port is set at the port of the direct vibration conveying channel.

[0111] Combination Figure 9 The structure and principle of the first detection device 5 and the second detection device 11 are the same. Here, the first detection device 5 will be used as an example for further explanation.

[0112] The first detection device 5 includes a detection rod 501, a sensor 502, a second lifting drive 503, and a support plate 504. One end of the detection rod 501 is mounted on the support plate 504, and the other end is vertically downward. The sensor 502 is mounted on the support plate 504 and is used to detect the position of the detection rod 501. The second lifting drive 503 is connected to the support plate 504 to drive the support plate 504 to move up and down and insert into the receiving cavity of the plastic part F. That is, the second lifting drive 503 drives the detection rod 501 downward to detect, and the sensor 502 determines the position of the detection rod 501 to determine the presence or absence of the spring B.

[0113] The second lifting drive component 503 can be a three-axis cylinder structure.

[0114] Combination Figures 10-12The structure and principle of the first static valve core feeding device 6 and the second static valve core feeding device 12 are the same. Here, we will take the first static valve core feeding device 6 as an example for further explanation.

[0115] The first stationary valve core device 6 includes a turntable 601 and a stationary valve core supply assembly 602, a second tilting device 603, and a sealing ring supply assembly 604 arranged around the outer periphery of the turntable 601; the turntable 601 is provided with a plurality of carriers (not shown) suitable for placing the stationary valve core C; the stationary valve core supply assembly 602 has a third vibrating plate 6021, a stationary valve core gripper 6022, and a second drive assembly 6023, the third vibrating plate 6021 is equipped with the stationary valve core C and is suitable for transferring the stationary valve core C to its outlet. The material inlet and the second drive assembly 6023 are connected to the static valve core gripper 6022 to drive the static valve core gripper 6022 to pick up the static valve core C from the discharge port and transfer the static valve core C to the carrier, or to transfer the static valve core C with the sealing ring D on the carrier to the receiving cavity of the plastic part F and abut against the spring B; that is, in addition to feeding the static valve core C to the carrier, the static valve core gripper 6022 can also feed the static valve core C with the sealing ring D to the receiving cavity of the plastic part F in the tooling 101 on the circulating conveyor line 1.

[0116] The second flipping device 603 is adapted to flip the stationary valve core C 180° to change the orientation of its end face, or to move the stationary valve core C with the sealing ring on the carrier into the receiving cavity of the plastic part F and abut against the spring B; that is, the second flipping device 603 can adjust the orientation of the stationary valve core C or feed the stationary valve core C with the sealing ring D into the receiving cavity of the plastic part F in the tooling 101 on the circulating conveyor line 1. Regarding the adjustment of the orientation of the stationary valve core C, since its end with the sealing ring D faces downwards when it is fed to the carrier, making it inconvenient to install the sealing ring D, the second flipping device 603 is used to adjust its orientation.

[0117] The sealing ring supply assembly 604 includes a fourth vibratory plate 6041, a sealing ring gripper 6042, and a third drive assembly 6043. The fourth vibratory plate 6041 houses the sealing ring D and is adapted to move the sealing ring D to its outlet. The third drive assembly 6043 is connected to the sealing ring gripper 6042 to drive the sealing ring gripper 6042 to pick up the sealing ring D from the outlet and move the sealing ring D onto the stationary valve core C on the carrier. In other words, the sealing ring supply assembly 604 provides the sealing ring D and then fits it onto the stationary valve core C on the carrier.

[0118] Specifically, for the static valve core supply assembly 602, a first transfer plate is provided at the discharge port of the third vibrating plate 6021. The first transfer plate is provided with a positioning groove suitable for receiving the static valve core. The first transfer plate is movable between the position where the positioning groove communicates with the discharge port and the position for feeding and discharging materials. The second drive assembly 6023 may include a lifting cylinder driven moving pair structure and a horizontal moving cylinder driven moving pair structure. The static valve core gripper 6022 is provided on the moving end of the lifting cylinder driven moving pair structure, and the lifting cylinder is provided on the moving end of the horizontal moving cylinder driven moving pair.

[0119] The second flipping device 603 may include a first transfer gripper 6031 and a second transfer gripper 6032. The first transfer gripper 6031 is mounted on a rotary cylinder, and the second transfer gripper 6032 is mounted on a lifting cylinder drive moving pair structure. The lifting cylinder drive moving pair structure is mounted on a moving pair structure driven by a horizontal moving cylinder. Thus, after the second transfer gripper 6032 picks up the stationary valve core C from the carrier, it transfers it to the first transfer gripper 6031. After the first transfer gripper 6031 rotates 180°, the second transfer gripper 6032 picks up the stationary valve core C from the first transfer gripper 6031 and puts the stationary valve core C back into the carrier.

[0120] For the turntable 601, a rotation drive component can be provided on the turntable 601 so that the turntable 601 rotates between the static valve core supply assembly 602, the second flipping device 603 and the sealing ring supply assembly 604.

[0121] For the sealing ring supply assembly 604, its sealing ring gripper 6042 can use a lifting cylinder in conjunction with the gripper's opening to grab the sealing ring D, and then use the gripper's structure to place the sealing ring D onto the stationary valve core C. The sealing ring gripper 6042 uses existing grippers and will not be described in detail here. The third drive assembly 6043 may include a lowering cylinder-driven moving pair structure and a horizontal moving cylinder-driven moving pair structure. The sealing ring gripper 6042 is located on the moving end of the lowering cylinder-driven moving pair structure, and the lowering cylinder is located on the moving end of the horizontal moving cylinder-driven moving pair.

[0122] The third vibratory plate 6021 and the fourth vibratory plate 6041 can be connected to the direct vibration conveying channel to facilitate the vibration discharge of the static valve core C and the sealing ring D. The discharge port is set at the port of the direct vibration conveying channel.

[0123] Combination Figure 13 The structure and principle of the first outer frame feeding device 7 and the second outer frame feeding device 13 are the same. Here, we will take the first outer frame feeding device 7 as an example for further explanation.

[0124] The first outer frame feeding device 7 includes a fifth vibratory plate 701, a second transfer plate 702, an outer frame gripper 703, and a fourth drive assembly 704. The fifth vibratory plate 701 is equipped with an outer frame E and is adapted to transfer the outer frame E to its outlet. The second transfer plate 702 is provided with a positioning groove adapted to receive the outer frame. The second transfer plate 702 is movable between a position where the positioning groove communicates with the outlet and a position for feeding and discharging material. The fourth drive assembly 704 is connected to the outer frame gripper 703 to drive the outer frame gripper 703 to pick up the outer frame E from the positioning groove and transfer the outer frame E to the plastic part F that is clamped on the tooling. Specifically, the fourth drive assembly 704 may include a rotary cylinder, a lifting cylinder, and a moving cylinder. The outer frame gripper 703 is disposed on the rotary cylinder, the rotary cylinder is disposed on the moving end of the lifting cylinder, and the lifting cylinder is disposed on the moving end of the moving cylinder. Thus, the outer frame gripper 703 can grip the outer frame E and adjust the orientation of the outer frame E to move it to the plastic part F. The outer frame E is then engaged with the plastic part F by the movement of the moving cylinder.

[0125] The fifth vibratory plate 701 can be connected to a direct vibration conveying channel to facilitate the vibration discharge of the outer frame E. The discharge port is located at the port of the direct vibration conveying channel.

[0126] Combination Figure 15 After the first outer frame is assembled, the tooling 101 is conveyed to the labeling device 15. The labeling device 15 includes a label peeler 1501, a suction block 1502, and a sixth drive assembly 1503. The label peeler 1501 peels off the label, the suction block 1502 picks up the label, and the label is affixed to the side of the plastic part F or the outer frame under the drive of the sixth drive assembly 1503. The sixth drive assembly 1503 may include a rotary cylinder, a lifting cylinder-driven moving pair structure, and a moving cylinder-driven moving pair structure. The suction block 1502 is mounted on the rotary cylinder, the rotary cylinder is mounted on the moving end of the lifting cylinder-driven moving pair structure, and the lifting cylinder is mounted on the moving end of the moving pair driven by the horizontal moving cylinder. The label peeler uses an existing structure and will not be described in detail here.

[0127] Combination Figure 14 The structure of the first flipping device 8 is the same as that of the second flipping device. The first flipping device 8 includes a third transfer gripper 801 and a fourth transfer gripper 802. The third transfer gripper 801 is mounted on a rotary cylinder, and the fourth transfer gripper 802 is mounted on a lifting cylinder driven moving pair structure. The lifting cylinder driven moving pair structure is mounted on a moving pair structure driven by a horizontal moving cylinder. Thus, after the fourth transfer gripper 802 picks up the plastic part from the tooling 101, it is transferred to the third transfer gripper 801. After the third transfer gripper 801 rotates 180°, the fourth transfer gripper 802 picks up the plastic part F from the third transfer gripper 801 and puts it back into the tooling 101.

[0128] Combination Figure 16The testing device 14 includes a loading gripper 1401, a discharging gripper 1402, an air tightness detection position 1403, an air leakage detection position 1404, a pressure resistance detection position 1405, and a testing instrument 1406. The air tightness detection position 1403, the air leakage detection position 1404, and the pressure resistance detection position 1405 are arranged side by side, and a transfer gripper 1407 is provided between adjacent detection positions. The air tightness detection position 1403, the air leakage detection position 1404, and the pressure resistance detection position 1405 are electrically connected to the testing instrument 1406. The loading gripper 1401 is adapted to pick up the plastic part after the second outer frame is clamped from the tooling 101 on the circulating conveyor line 1 and transfer the plastic part after the second outer frame is clamped to the detection position. The discharging gripper 1402 is adapted to unload the plastic part after it has been detected at the detection position to the qualified product area or the unqualified product area.

[0129] Specifically, the loading gripper 1401 may be composed of a third lifting drive 14011, a first conveying drive 14012 and a loading gripper 14013; the loading gripper 14013 is disposed at the moving end of the third lifting drive 14011, and the third lifting drive 14011 is disposed at the moving end of the first conveying drive 14012.

[0130] Understandably, by setting the loading claw 14013 at the moving end of the third lifting drive 14011, and the third lifting drive 14011 at the moving end of the first conveying drive 14012, the tooling 101 on the circulating conveyor line 1 can clamp the plastic part after the second outer frame is clamped and transfer the plastic part after the second outer frame is clamped to the detection position for detection. The third lifting drive 14011 can be a cylinder-driven moving pair structure, and the first conveying drive 14012 can be a motor-driven linear module structure.

[0131] The testing device 14 also includes a temporary storage section 1408, which is located between the loading gripper 1401 and the transfer gripper 1407. The loading gripper 1401 transfers the plastic part after the second outer frame is clamped to the temporary storage section 1408, and then the transfer gripper 1407 transfers the plastic part in the temporary storage section 1408 to each testing station. This can improve the cycle time of the loading gripper 1401 and the transfer gripper 1407, thereby improving efficiency.

[0132] The unloading gripper 1402 has the same structure as the plastic part loading device 2. For details, please refer to... Figure 5 The difference is that the unloading claw 1402 is suitable for unloading the plastic parts after detection at the detection position to the qualified product area or the unqualified product area (collection box).

[0133] For the conveying gripper 1407, the air tightness detection position 1403, the air leakage detection position 1404 and the pressure resistance detection position 1405 are arranged side by side and a conveying gripper 1407 is provided between two adjacent detection positions.

[0134] Specifically, the conveying gripper 1407 includes a second conveying drive 14071 and a fourth lifting drive 14072, with the fourth lifting drive 14072 disposed at the moving end of the second conveying drive 14071. Understandably, the second conveying drive 14072 can drive the fourth lifting drive 14071 closer to the temporary storage section 1408 and convey the plastic parts on the temporary storage section 1408 to each inspection station for inspection, thereby ensuring the quality of the solenoid valve assembly. The fourth lifting drive 14072 can be a cylinder structure, with several spaced-apart grippers on the mounting plate connected to the cylinder. Multiple fourth lifting drive 14072s are then disposed on a support plate, which is driven by the second conveying drive 14071, which can be a motor-driven linear module.

[0135] The conveying gripper 1407, located between two adjacent detection positions of air tightness detection position 1403, air leakage detection position 1404, and pressure resistance detection position 1405, allows the plastic part after being snapped into the second outer frame to be conveyed between the air tightness detection position 1403, air leakage detection position 1404, and pressure resistance detection position 1405, thereby ensuring the quality of the solenoid valve assembly.

[0136] For the air tightness detection position 1403, the air tightness detection position 1403 is electrically connected to the detector 1406. The air tightness detection position 1403 can adopt the existing structure. The air tightness detection position 1403 can be used to detect whether the assembled solenoid valve is leaking, thereby ensuring the quality of the solenoid valve assembly.

[0137] For the leak detection position 1404, the leak detection position 1404 is connected to the detector 1406. The leak detection position 1404 can adopt the existing structure. The leak detection position 1404 can be used to detect whether the exhaust of the assembled solenoid valve is unobstructed, thereby ensuring the quality of the solenoid valve assembly.

[0138] For the pressure resistance test position 1405, the pressure resistance test position 1405 is connected to the tester 1406. The pressure resistance test position 1405 can adopt the existing structure. The pressure resistance of the assembled solenoid valve can be detected through the pressure resistance test position 1405, thereby ensuring the quality of the solenoid valve assembly.
