They are actuators and are not limited to hydraulics or pneumatics. They are used in industrial control systems to adjust the direction, flow, speed and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, and the control accuracy and flexibility can be guaranteed. There are many types of solenoid valves, and different solenoid valves play a role in different positions in the control system. The most commonly used ones are check valves, safety valves, directional control valves, speed regulating valves, etc. It is a widely used valve body structure. The main structure of a common solenoid valve is usually composed of components such as the valve body, valve stem, pilot valve seat and coil.

[0003] At present, during the assembly and production process of solenoid valves, it is necessary to assemble components such as the valve body, valve stem, pilot valve seat and coil. Generally, the valve stem is first aligned with the inside of the valve body and inserted. After insertion, the pilot valve seat is installed at the end of the valve body, and the pilot valve seat and the valve body are fixed with screws. Then, a high-strength coil is installed on the side of the pilot valve seat and a coil nut is screwed into the end of the coil. The assembly process is usually performed manually due to the high cost, complex structure and inconvenient maintenance of automated equipment. The assembly between the components depends entirely on manual docking and tightening, which requires a large amount of manual labor and low production efficiency. Therefore, a solenoid valve assembly device is proposed. Through the cooperation of various components, the orderly feeding of the various components of the solenoid valve is realized, the feeding position accuracy is guaranteed, and it is convenient for manual labor to perform rapid assembly operations, reduce the amount of manual operation, and improve the assembly efficiency of the solenoid valve. Summary of the Invention

[0005] The technical solution adopted by the present invention to solve its technical problem is a solenoid valve assembly device, comprising a base, a horizontally arranged transverse slot for moving the solenoid valve assembly inside the base, a feeding rack A provided on the side of the end of the base, a connecting cavity connected to the interior of the transverse slot and a storage cavity provided on the side of the connecting cavity inside the feeding rack A;

[0006] The inside of the feeding rack A is located at the end position of the storage cavity and is movably connected to a push plate A through a spring A. A sleeve is vertically fixed to the top of the base near one end of the feeding rack A. The top of the sleeve is movably connected to a movable column through a spring B, and the side of the movable column extends to the outside of the sleeve. A pressure ring is integrally formed at the bottom of the movable column. An oblique storage rack is welded on the side of the sleeve, and an insertion cavity is opened at the top of the oblique storage rack near the sleeve position. The side of the movable column is fixedly connected to a dividing plate that passes through the insertion cavity and extends to the inside of the oblique storage rack.

[0007] By adopting the above technical solution, the interior of the feed rack A is used to place the solenoid valve body structure to be assembled. When placing it, the push plate A is moved toward the end of the inner wall of the storage cavity, the spring is compressed, and the solenoid valve body structure is placed in order inside the storage cavity with the valve stem insertion end facing upward. During operation, the solenoid valve body moves horizontally into the connecting cavity and then into the transverse groove, and its top valve stem insertion end is aligned with the bottom end of the sleeve. By pulling down the movable column, the solenoid valve stem located inside the sleeve can be pressed into the solenoid valve body through the pressure ring.

[0008] Specifically, a feeding rack B is provided at the top of the base near the side of the sleeve, and a push plate B is movably connected to the inside of the feeding rack B through a spring C. A positioning seat is welded to the side of the top of the base near the feeding rack B, and a U-shaped groove is provided at the bottom end of the positioning seat. A connecting rod passing through the U-shaped groove is inserted into the positioning seat, and a positioning ring is welded on the outer wall of the connecting rod to fit the upper and lower sides of the U-shaped groove.

[0009] By adopting the above technical solution, the interior of the feed rack B is used to store the solenoid valve pilot seat, the spring C is compressed, the solenoid valve pilot seat is placed in order between the push plate B and the inner wall of the feed rack B with its connecting end facing downward, and the solenoid valve body after the solenoid valve stem is installed slides to the bottom of the feed rack B, the solenoid valve pilot seat is removed and connected to the solenoid valve body, and then slides to the bottom of the pneumatic screw gun connected to the connecting rod, the C-shaped groove structure specifications are customized according to the specifications of the solenoid valve pilot seat connection end, so that the spacing between the four corners inside the C-shaped groove corresponds to the installation position of the four screws at the end of the solenoid valve pilot seat, at this time, the connecting rod is slid along the C-shaped groove to adjust the position of the pneumatic screw gun, as long as the connecting rod slides to the end position of the C-shaped groove, it can ensure that the output end position of the pneumatic screw gun is aligned with the screw insertion position, which facilitates and quickly screws in to tighten the solenoid valve body and the solenoid valve pilot seat.

[0010] Specifically, a feeding rack C is provided on the side of the feeding rack B away from the sleeve, and the inner wall end of the feeding rack C is movably connected to the push plate C through a spring D. A bracket is welded horizontally on the side of the feeding rack C and a through groove is opened inside the bracket. A fixing rod is provided on the top of the base at the side of the feeding rack C.

[0011] By adopting the above technical solution, the interior of the feed rack C is used to store the solenoid valve coil, and the protruding end of the solenoid valve coil faces downward and is just inserted into the through groove inside the bracket, so that the solenoid valve coil can be placed in an orderly manner inside the feed rack C. The solenoid valve body and the solenoid valve pilot valve seat assembly are moved to the bottom end of the feed rack C, and the solenoid valve coil is removed and inserted into the outer periphery of the end of the solenoid valve pilot valve seat, and then slid to the bottom of the pneumatic screw gun connected to the fixed rod. The coil nut is fed into the external feeding equipment connected to the feed pipe and screwed into the end of the solenoid valve coil using the pneumatic screw gun to complete the assembly of the solenoid valve.

[0012] Specifically, the ends of the fixed rod and the connecting rod are movably connected with rings, the sides of the rings are provided with vertical grooves, and the top of the inner wall of the vertical groove is movably connected with a slider through a spring E, the ends of the fixed rod and the connecting rod are fixed to the sides of the slider, and a pneumatic screw gun is inserted into the inside of the ring, and a feeding pipe connected to an external feeding device is installed on the side of the bottom end of the pneumatic screw gun.

[0013] By adopting the above technical solution, the pneumatic screw gun is vertically inserted into the collar. When not in use, the ends of the fixing rod and the connecting rod are located at the bottom of the collar side. The collar and the pneumatic screw gun are relatively high and do not affect the movement of the bottom objects. When the solenoid valve moves to the bottom of the pneumatic screw gun, the collar is pressed down to compress the spring E, and the slider slides inside the vertical groove, which can drive the pneumatic screw gun to move downward through the collar to screw in the screw. After the operation is completed, the collar is loosened to drive the pneumatic screw gun to reset.

[0014] Specifically, a transverse groove is opened horizontally inside the transverse groove near one end of the feed rack A, and a movable plate is movably connected to the inside of the transverse groove through a spring F. The movable plate is located inside the transverse groove and a connecting plate is welded on its side, which extends to the outside of the base and horizontally passes through the inside of the feed rack A. A triangular limit block A is movably connected to the corresponding position of the side of the connecting cavity inside the movable plate through a rotating shaft, and a triangular limit block B is movably connected to the position of the storage cavity inside the connecting plate through a rotating shaft, and a torsion spring A is installed at the end connection of the triangular limit block A and the end connection of the triangular limit block B. The end position of the inner wall of the connecting cavity is movably connected to a trapezoidal push block through a spring G.

[0015] By adopting the above technical solution, a movable plate is installed at the inner end position of the transverse groove through the transverse groove and the spring F. When the solenoid valve body enters the transverse groove, its end just fits into the right-angled side position of the triangular limit block A. At this time, the triangular limit block A plays a limiting role on it. After the installation of the solenoid valve stem is completed, the solenoid valve body is slid, and the movable plate will be pushed and drive the movement of the connecting plate at the same time. When the connecting plate moves, the right-angled edge of the triangular limit block B on its top pushes the solenoid valve body located at the end of the storage chamber to move toward the inside of the connecting chamber. During the movement, the solenoid valve body will squeeze the hypotenuse of the trapezoidal push block, so that the spring G is in a compressed state. When the triangular limit block A moves to the end of the transverse groove When the spring F is released, the inner wall of the end of the transverse groove will squeeze the inclined edge of the triangular limit block A, causing it to be compressed and lowered to the bottom position of the solenoid valve body. At this time, the spring F loses its limit and drives the movable plate to reset horizontally under the action of its elastic force. The connecting plate is reset at the same time, and the triangular limit block B is compressed and retracted inside the connecting plate, so that it can pass through the side of the feed rack A. At this time, the spring G inside the connecting cavity loses its limit. When it is reset, it will push the solenoid valve body to be assembled inside the connecting cavity into the valve stem installation position inside the transverse groove, which is convenient for subsequent rapid assembly operations. After the movable plate and the connecting plate are reset in place, the triangular limit block A and the triangular limit block B are unfolded again under the action of the torsion spring A, and can be used continuously in the future.

[0016] Specifically, the internal discharge ends of the feeding rack B and the feeding rack C are both provided with empty slots in the vertical direction, the top of the inner wall of the empty slot is movably connected to the limit frame through a spring H, and the end of the limit frame is inserted into the feeding rack, the internal discharge ends of the feeding rack B and the feeding rack C are both provided with preparation troughs, and the side of the inner wall of the preparation trough is provided with grooves, the top of the inner top of the groove is movably connected to a supporting plate through a rotating shaft, and the top of the supporting plate is flush with the top of the preparation trough, and a torsion spring B is installed between the connection of the end of the supporting plate and the inner wall of the groove.

[0017] By adopting the above technical solution, the solenoid valve pilot valve seat located inside the feeding rack B and the solenoid valve coil located inside the feeding rack C are arranged in order, and the components near the end position will be placed on the top of the preparation trough. Under normal conditions, the supporting plate is lifted up by the torsion spring B, which temporarily supports the objects to be taken. When it is necessary to take materials, the limit rack is pressed down to make it slide down along the preparation trough and press down the materials. After being pressed, the supporting plate will squeeze the torsion spring B and shrink into the groove. After shrinking into place, the materials at the ends of the feeding racks B and C can be discharged from the preparation trough position. After discharge, the limit rack is reset under the action of the spring H and manpower, and the supporting plate is reset under the action of the torsion spring B. During the process of the limit rack being pressed down, its end will resist the materials inside the feeding racks B and C, so that they will not slide. When the limit rack is reset, the push plate structure will push the materials to move so that the new materials to be used are moved to the top of the preparation trough.

[0018] Specifically, slots are provided at intervals on the sides of the base and positioning plates are inserted into the slots. The positions of the positioning plates correspond to the positions of the sides of the feed rack B, the feed rack C and the pneumatic screw gun respectively.

[0019] By adopting the above technical solution, the slot position is designed according to the installation position of the feed rack B, feed rack C and pneumatic screw gun, so that after the plug-in plate is inserted, it plays a limiting role on the solenoid valve assembly. When the solenoid valve assembly slides along the transverse groove and the end is attached to the plug-in plate, it is ensured that the solenoid valve assembly is exactly aligned with the feed assembly or screw gun position at the corresponding position, which is convenient and quick processing.

[0020] Specifically, the top of the sleeve is fixedly connected to a bottom ring and a rubber ring is bonded inside the bottom ring. A through hole corresponding to the position of the pressure ring is opened at the center position of the rubber ring, and a cross groove is opened inside the rubber ring at the position of the through hole.

[0021] By adopting the above technical solution, a rubber ring structure is provided inside the bottom ring. When no external force is applied, the end of the solenoid valve stem inside the sleeve is aligned with the position of the through hole, and is supported by the rubber ring so that it is temporarily located inside the sleeve. When the pressure ring presses down the solenoid valve stem, the bottom of the solenoid valve stem squeezes the through hole, causing the cross groove to expand, thereby allowing the solenoid valve stem assembly to be discharged normally to the outside of the sleeve.

[0022] Specifically, the bottom of the inner wall of the feeding rack A, the feeding rack B and the feeding rack C are all provided with a guide groove, and the bottom ends of the push plates A, the push plates B and the push plates C are all installed with a guide block inserted into the guide groove.

[0023] By adopting the above technical solution, the bottom of push plates A, B and C are all provided with guide blocks located inside the guide grooves. Through the cooperation of the guide grooves and the guide blocks, the push plate structure can only slide in the horizontal direction.

[0024] Specifically, a fixed plate is fixedly connected to one end of the transverse groove, a movable plate is welded to the outer periphery of the movable plate, and both ends of the spring F are respectively connected to the sides of the movable plate and the fixed plate. The fixed plate, movable plate and spring F are all located inside the transverse groove.

[0025] By adopting the above technical solution, the fixed plate and the movable plate are used to install the spring F, and the movement of the movable plate can drive the movement of the movable plate and stretch the spring F.

[0026] Beneficial effects of the present invention:

[0027] (1) The solenoid valve assembly equipment described in the present invention is used to place the solenoid valve body structure to be assembled inside the feeding rack A, and the solenoid valve body structure is placed in order inside the storage cavity with the valve stem insertion end facing upward. During operation, the solenoid valve body moves horizontally into the connecting cavity and then is discharged into the transverse groove, and its top valve stem insertion end is just aligned with the bottom end of the sleeve. The inclined storage rack is used to place the solenoid valve stems in order, and the solenoid valve stem at the end is located inside the sleeve. The movable column and the pressure ring are connected to the top position inside the sleeve by a spring. When the solenoid valve body is aligned with the bottom of the sleeve, the movable column can be pulled down to press the solenoid valve stem located inside the sleeve into the solenoid valve body through the pressure ring, and the assembly of the solenoid valve body and the solenoid valve stem is quickly completed. During the downward pressing process of the movable column, the dividing plate is inserted into the inclined storage rack through the insertion cavity to prevent the internal solenoid valve stem assembly from moving. When the dividing plate is reset, the solenoid valve stem at the end slides into the sleeve for standby use.

[0028] (2) The solenoid valve assembly equipment described in the present invention has a feed rack B for storing the solenoid valve pilot seat with its connection end facing downward. After the solenoid valve stem is installed, the solenoid valve body slides to the bottom of the feed rack B, the solenoid valve pilot seat is removed and connected to the solenoid valve body, and then slides to the bottom of the pneumatic screw gun connected to the connecting rod. The specifications of the U-shaped groove structure are customized according to the specifications of the connecting end of the solenoid valve pilot seat, so that the spacing between the four corners of the U-shaped groove corresponds to the installation position of the four screws at the end of the solenoid valve pilot seat. At this time, the position of the pneumatic screw gun is adjusted by sliding the connecting rod along the U-shaped groove. As long as the connecting rod slides to the end position of the U-shaped groove, the output end position of the pneumatic screw gun can be aligned with the screw insertion position, which facilitates the quick screwing in of the screw to tighten the solenoid valve body and the solenoid valve pilot seat, thereby improving the convenience of the assembly process.

[0029] (3) The solenoid valve assembly equipment described in the present invention is used to store the solenoid valve coil inside the feeding rack C, and the solenoid valve coil is placed in an orderly manner inside the feeding rack C. The solenoid valve body and the solenoid valve pilot valve seat assembly are moved to the bottom end of the feeding rack C, and the solenoid valve coil is removed and inserted into the outer periphery of the end of the solenoid valve pilot valve seat, and then slid to the bottom of the pneumatic screw gun connected to the fixed rod. The coil nut is fed into the external feeding device connected to the feeding pipe and screwed into the end of the solenoid valve coil using the pneumatic screw gun to complete the assembly of the solenoid valve. Through the cooperation of various components, the orderly feeding of various components of the solenoid valve is realized, the feeding position accuracy is guaranteed, and it is convenient for manual labor to perform rapid assembly operations, reduce the amount of manual operation, and improve the assembly efficiency of the solenoid valve.

[0030] (4) The solenoid valve assembly device described in the present invention is provided with a movable plate installed at the inner end position of the transverse groove through the transverse groove and the spring F. When the solenoid valve body enters the transverse groove, its end just fits into the right-angled side position of the triangular limit block A. At this time, the triangular limit block A plays a limiting role on it. After the installation of the solenoid valve stem is completed, the solenoid valve body is slid, and the movable plate will be pushed and the connecting plate will be driven to move at the same time. When the connecting plate moves, the right-angled side of the triangular limit block B on its top pushes the solenoid valve body located at the end of the storage cavity to move into the connecting cavity. During the movement, the solenoid valve body squeezes the hypotenuse of the trapezoidal push block, so that the spring G is in a compressed state. When the triangular limit block A moves to the end of the transverse groove, the inner wall of the end of the transverse groove squeezes the triangular limit block A. The inclined edge compresses and lowers it to the bottom position of the solenoid valve body. At this time, the spring F loses its limit and, under the action of its elastic force, drives the movable plate to reset horizontally. The connecting plate resets at the same time, and the triangular limit block B is compressed and retracted inside the connecting plate, so that it can pass through the side of the feed rack A. At this time, the spring G inside the connecting cavity loses its limit. When it resets, it pushes the solenoid valve body to be assembled inside the connecting cavity into the valve stem installation position inside the transverse groove, which is convenient for subsequent rapid assembly operations. After the movable plate and the connecting plate are reset in place, the triangular limit block A and the triangular limit block B are re-expanded under the action of the torsion spring A, and can be used continuously in the subsequent process. Through the cooperation of various components, the automatic loading of the solenoid valve body structure can be realized, further improving the assembly convenience and assembly efficiency.

The side of the movable column 207 is fixedly connected to a dividing plate 209 that passes through the insertion cavity 211 and extends to the inside of the oblique storage rack 210.

[0048] When in use, the interior of the feeding rack A2 is used to place the solenoid valve body 6 structure to be assembled. When placing it, the push plate A204 is moved toward the end of the inner wall of the storage chamber 201, and the spring A203 is compressed, so that the solenoid valve body 6 structure is placed in order inside the storage chamber 201 with the valve stem insertion end facing upward. During operation, the solenoid valve body 6 moves laterally into the connecting chamber 202 and then is discharged into the transverse groove 101, and its top valve stem insertion end is just aligned with the bottom end of the sleeve 205. By pulling down the movable column 207, the solenoid valve stem 601 located inside the sleeve 205 can be pressed into the interior of the solenoid valve body 6 through the pressure ring 208.

The specifications of the end are customized so that the spacing between the four corners of the U-shaped groove 304 corresponds to the installation positions of the four screws 603 at the end of the solenoid valve pilot seat 602. At this time, the connecting rod 305 is slid along the U-shaped groove 304 to adjust the position of the pneumatic screw gun 7. As long as the connecting rod 305 slides to the end position of the U-shaped groove 304, the output end position of the pneumatic screw gun 7 can be aligned with the insertion position of the screw 603, which facilitates the quick screwing in of the screw 603 to tighten the solenoid valve body 6 and the solenoid valve pilot seat 602.

[0051] Specifically, a feeding rack C4 is provided on the side of the feeding rack B3 away from the sleeve 205, and the inner wall end of the feeding rack C4 is movably connected to the push plate C402 through a spring D401. A bracket 403 is welded horizontally on the side of the feeding rack C4 and a through groove 404 is opened inside the bracket 403. A fixing rod 405 is provided on the top of the base 1 at the side of the feeding rack C4.

[0052] When in use, the interior of the feed rack C4 is used to store the solenoid valve coil 604. The protruding end of the solenoid valve coil 604 faces downward and is inserted into the through groove 404 inside the bracket 403, so that the solenoid valve coil 604 can be placed in an orderly manner inside the feed rack C4. The solenoid valve body 6 and the solenoid valve pilot valve seat 602 combination are moved to the bottom end of the feed rack C4, and the solenoid valve coil 604 is removed and inserted into the outer periphery of the end of the solenoid valve pilot valve seat 602, and then slid to the bottom of the pneumatic screw gun 7 connected to the fixed rod 405. The coil nut 605 is fed into the external feeding equipment connected to the feeding pipe 701 and screwed into the end of the solenoid valve coil 604 using the pneumatic screw gun 7 to complete the assembly of the solenoid valve.

[0056] By adopting the above technical solution, the bottom of push plate A204, push plate B302 and push plate C402 are all provided with a guide block 501 located inside the guide groove 5. Through the cooperation between the guide groove 5 and the guide block 501, the push plate structure can only slide in the horizontal direction.

[0057] Specifically, a fixed plate 801 is fixedly connected to one end of the transverse groove 8, a movable plate 804 is welded to the outer periphery of the movable plate 803, and both ends of the spring F802 are respectively connected to the sides of the movable plate 804 and the fixed plate 801, and the fixed plate 801, the movable plate 804 and the spring F802 are all located inside the transverse groove 8.

[0058] By adopting the above technical solution, the fixed plate 801 and the movable plate 804 cooperate to install the spring F802, and at the same time, the movement of the movable plate 803 can drive the movement of the movable plate 804 and stretch the spring F802.

[0059] When in use, the interior of the feeding rack A2 is used to place the solenoid valve body 6 structure to be assembled. When placing, the push plate A204 is moved toward the end of the inner wall of the storage chamber 201, the spring is compressed, and the solenoid valve body 6 structure is placed in order inside the storage chamber 201 with the valve stem insertion end facing upward. During operation, the solenoid valve body 6 moves horizontally into the connecting chamber 202 and then is discharged into the transverse groove 101, and its top valve stem insertion end is just aligned with the bottom end of the sleeve 205. Pulling down the movable column 207 can press the solenoid valve stem 601 located inside the sleeve 205 into the interior of the solenoid valve body 6 through the pressure ring 208. The interior of the oblique storage rack 210 is used to place the solenoid valve stem 601 in order, and the solenoid valve stem 601 at the end is located in the sleeve 20 5, the movable column 207 and the pressure ring 208 are connected to the top position of the sleeve 205 through the spring. When the solenoid valve body 6 is aligned with the bottom of the sleeve 205, the movable column 207 is pulled down to press the solenoid valve stem 601 located inside the sleeve 205 into the solenoid valve body 6 through the pressure ring 208, and the assembly of the solenoid valve body 6 and the solenoid valve stem 601 is quickly completed. The dividing plate 209 is inserted into the interior of the oblique storage rack 210 through the insertion cavity 211 to prevent the internal solenoid valve stem 601 assembly from moving. When the dividing plate 209 is reset, the end of the solenoid valve stem 601 slides into the interior of the sleeve 205 for standby use. The interior of the feed rack B3 is used to store the solenoid valve pilot seat 602. The spring C301 is compressed and the push plate B The solenoid valve pilot seat 602 is placed in order between 302 and the inner wall of the feeding rack B3 with its connecting end facing downward. After the solenoid valve stem 601 is installed, the solenoid valve body 6 slides to the bottom of the feeding rack B3, the solenoid valve pilot seat 602 is removed and connected to the solenoid valve body 6, and then slides to the bottom of the pneumatic screw gun 7 connected to the connecting rod 305. The structural specifications of the U-shaped groove 304 are customized according to the specifications of the connecting end of the solenoid valve pilot seat 602, so that the internal four corners spacing of the U-shaped groove 304 corresponds to the installation position of the four screws 603 at the end of the solenoid valve pilot seat 602. At this time, slide the connecting rod 305 along the U-shaped groove 304 to adjust the position of the pneumatic screw gun 7. As long as the connecting rod 305 slides to the end position of the U-shaped groove 304, This can ensure that the output end position of the pneumatic screw gun 7 is aligned with the position where the screw 603 is driven in, so that the screw 603 can be quickly screwed in to tighten the solenoid valve body 6 and the solenoid valve pilot valve seat 602. The interior of the feed rack C4 is used to store the solenoid valve coil 604. The protruding end of the solenoid valve coil 604 faces downward and is just inserted into the through groove 404 inside the bracket 403, so that the solenoid valve coil 604 can be placed in an orderly manner inside the feed rack C4. Move the solenoid valve body 6 and the solenoid valve pilot valve seat 602 assembly to the bottom end position of the feed rack C4, remove the solenoid valve coil 604 and insert it into the outer periphery of the end of the solenoid valve pilot valve seat 602, and then slide it to the bottom of the pneumatic screw gun 7 connected to the fixing rod 405.The solenoid valve assembly operation can be completed by feeding the coil nut 605 into the external feeding equipment connected to the feeding pipe 701 and screwing it into the end of the solenoid valve coil 604 using the pneumatic screw gun 7. The pneumatic screw gun 7 is vertically inserted into the collar 702. When not in use, the ends of the fixing rod 405 and the connecting rod 305 are located at the bottom of the side of the collar 702. The collar 702 and the pneumatic screw gun 7 are relatively high and do not affect the movement of the bottom object. When the solenoid valve moves to the bottom of the pneumatic screw gun 7, the collar 702 is pressed down to compress the spring E705, and the slider 704 slides inside the vertical slot 703, which can drive the pneumatic screw gun 7 to move downward through the collar 702 to screw into the screw 603. After the operation is completed, the collar 702 is loosened to drive the pneumatic screw gun 7 to reset.

[0060] Example 2:

[0061] The technical solution adopted by the present invention to solve its technical problem is a solenoid valve assembly device, comprising a base 1, wherein a transverse movement slot 101 for moving the solenoid valve assembly is horizontally opened inside the base 1, a feeding rack A2 is provided on the side of the end of the base 1, a connecting cavity 202 connected to the interior of the transverse movement slot 101 is opened inside the feeding rack A2, and a storage cavity 201 is opened on the side of the connecting cavity 202 inside the feeding rack A2;

[0062] The inside of the feeding rack A2 is located at the end position of the storage cavity 201 and is movably connected to a push plate A204 through a spring A203. A sleeve 205 is vertically fixed to the top of the base 1 near one end of the feeding rack A2. The top of the sleeve 205 is movably connected to a movable column 207 through a spring B206, and the side of the movable column 207 extends to the outside of the sleeve 205. A pressure ring 208 is integrally formed at the bottom of the movable column 207. An oblique storage rack 210 is welded to the side of the sleeve 205, and an insertion cavity 211 is provided at the top of the oblique storage rack 210 near the sleeve 205. The side of the movable column 207 is fixedly connected to a dividing plate 209 that passes through the insertion cavity 211 and extends to the inside of the oblique storage rack 210.

[0063] By adopting the above-mentioned technical solution, the interior of the feeding rack A2 is used to place the solenoid valve body 6 structure to be assembled. When placing it, the push plate A204 is moved toward the end of the inner wall of the storage chamber 201, and the spring is compressed to place the solenoid valve body 6 structure in an orderly manner inside the storage chamber 201 with the valve stem insertion end facing upward. During operation, the solenoid valve body 6 moves horizontally into the connecting chamber 202 and then is discharged into the transverse groove 101, and its top valve stem insertion end is just aligned with the bottom end of the sleeve 205. By pulling down the movable column 207, the solenoid valve stem 601 located inside the sleeve 205 can be pressed into the interior of the solenoid valve body 6 through the pressure ring 208.

[0064] Specifically, a transverse groove 8 is horizontally opened inside the transverse groove 101 near one end of the feeding rack A2, and a movable plate 803 is movably connected inside the transverse groove 8 through a spring F802. The movable plate 803 is located inside the transverse groove 8 and a connecting plate 805 is welded on its side, which extends to the outside of the base 1 and horizontally passes through the inside of the feeding rack A2. A triangular limit block A806 is movably connected to the corresponding position of the side of the connecting cavity 202 inside the movable plate 803 through a rotating shaft, and a triangular limit block B807 is movably connected to the position of the connecting plate 805 near the storage cavity 201 through a rotating shaft, and a torsion spring A808 is installed at the end connection of the triangular limit block A806 and the end connection of the triangular limit block B807. The end position of the inner wall of the connecting cavity 202 is movably connected to a trapezoidal push block 810 through a spring G809.

[0065] By adopting the above technical solution, a movable plate 803 is installed at the internal end position of the transverse groove 101 through the transverse groove 8 and the spring F802. When the solenoid valve body 6 enters the transverse groove 101, its end just fits into the right-angled side position of the triangular limit block A806. At this time, the triangular limit block A806 plays a limiting role on it. After the installation of the solenoid valve stem 601 is completed, the solenoid valve body 6 is slid, and the movable plate 803 will be pushed and drive the movement of the connecting plate 805. When the connecting plate 805 moves, the right-angled edge of the triangular limit block B807 on its top pushes the solenoid valve body 6 located at the end of the storage chamber 201 to move toward the inside of the connecting chamber 202. During the movement, the solenoid valve body 6 will squeeze the hypotenuse of the trapezoidal push block 810, so that the spring G809 is in a compressed state. When the triangular limit block A806 moves to the transverse groove 8 end, the inner wall of the end of the transverse groove 8 will squeeze the inclined edge of the triangular limit block A806, causing it to be compressed and lowered to the bottom position of the solenoid valve body 6. At this time, the spring F802 loses its limit, and under the action of its elastic force, the movable plate 803 is driven horizontally to reset, and the connecting plate 805 is reset at the same time. The triangular limit block B807 is compressed and retracted inside the connecting plate 805, so that it can pass through the side of the feed rack A2. At this time, the spring G809 inside the connecting cavity 202 loses its limit. When reset, it will push the solenoid valve body 6 to be assembled inside the connecting cavity 202 into the valve stem installation position inside the transverse groove 101, which is convenient for subsequent rapid assembly operations. After the movable plate 803 and the connecting plate 805 are reset in place, the triangular limit block A806 and the triangular limit block B807 are reopened under the action of the torsion spring A808, and can be used continuously in the future.

[0066] Specifically, the internal discharge ends of the feeding rack B3 and the feeding rack C4 are both provided with an empty slot 9 in the vertical direction, the top of the inner wall of the empty slot 9 is movably connected to the limit frame 902 through a spring H901, and the end of the limit frame 902 is inserted into the interior of the feeding rack, the internal discharge ends of the feeding rack B3 and the feeding rack C4 are both provided with a preparation trough 903, and the side of the inner wall of the preparation trough 903 is provided with a groove 904, the top of the inner top of the groove 904 is movably connected to a supporting plate 905 through a rotating shaft, and the top of the supporting plate 905 is flush with the top of the preparation trough 903, and a torsion spring B906 is installed between the connection at the end of the supporting plate 905 and the inner wall of the groove 904.

[0067] By adopting the above technical solution, the solenoid valve pilot valve seat 602 located inside the feeding rack B3 and the solenoid valve coil 604 located inside the feeding rack C4 are arranged in order, and the components close to the end position will be placed on the top of the preparation groove 903. Under normal conditions, the supporting plate 905 is lifted up by the torsion spring B906, and plays a temporary supporting role for the object to be taken. When it is necessary to take the material, the limit frame 902 is pressed down to slide down along the preparation groove 903 and press down the material. After being pressed, the supporting plate 905 will squeeze the torsion spring B906 and move it towards the groove 9 04 contracts internally. After contracting into place, the materials at the inner ends of the feeding racks B3 and C4 can be discharged from the preparation trough 903. After discharge, the limiting rack 902 is reset under the action of the spring H901 and manpower, and the supporting plate 905 is reset under the action of the torsion spring B906. During the downward pressure of the limiting rack 902, its end will contact the materials inside the feeding racks B3 and C4 to prevent them from slipping. When the limiting rack 902 is reset, the push plate structure will push the materials to move so that the new stand-by materials are moved to the top of the preparation trough 903.

[0068] Specifically, slots 102 are spaced apart on the sides of the base 1 and positioning plates 103 are inserted into the slots 102 . The positions of the positioning plates 103 correspond to the side positions of the feed rack B3 , the feed rack C4 and the pneumatic screw gun 7 , respectively.

[0069] By adopting the above technical solution, the position of the slot 102 is designed according to the installation position of the feed rack B3, the feed rack C4 and the pneumatic screw gun 7, so that after the plug-in plate is inserted, it plays a limiting role on the solenoid valve assembly. When the solenoid valve assembly slides along the transverse groove 101 and the end is attached to the plug-in plate, it is ensured that the solenoid valve assembly is exactly aligned with the feed assembly or screw gun position at the corresponding position, which is convenient for quick processing.

[0070] Specifically, a bottom ring 212 is fixedly connected to the top of the sleeve 205 and a rubber ring 213 is bonded inside the bottom ring 212. A through hole 214 corresponding to the position of the pressure ring 208 is opened at the center position inside the rubber ring 213, and a cross groove 215 is opened inside the rubber ring 213 at the position of the through hole 214.

[0071] By adopting the above technical solution, a rubber ring 213 structure is provided inside the bottom ring 212. When no external force is applied, the end of the solenoid valve stem 601 located inside the sleeve 205 is aligned with the through hole 214 and is supported by the rubber ring 213 so that it is temporarily located inside the sleeve 205. When the pressure ring 208 presses down the solenoid valve stem 601, the bottom of the solenoid valve stem 601 squeezes the through hole 214, causing the cross groove 215 to expand, thereby allowing the solenoid valve stem 601 assembly to be discharged normally to the outside of the sleeve 205.

[0072] When in use, the solenoid valve pilot valve seat 602 located inside the feeding rack B3 and the solenoid valve coil 604 located inside the feeding rack C4 are placed in order, and the components close to the end position will be placed on the top of the preparation groove 903. Under normal conditions, the supporting plate 905 is lifted up by the torsion spring B906, and it plays a temporary supporting role for the object to be taken. When it is necessary to take the material, the limit frame 902 is pressed down to make it slide down along the preparation groove 903 and press down the material. After being compressed, the supporting plate 905 will squeeze the torsion spring B906 and shrink into the groove 904. After shrinking into place, the materials at the inner ends of the feeding racks B3 and feeding racks C4 can be discharged from the preparation groove 903 position. After discharge, the limit frame 902 is reset under the action of the spring H901 and manpower, and the supporting plate 905 is reset on the torsion spring When the material is in the material preparation slot 903, the material is reset under the action of B906. During the downward pressure of the limit frame 902, its end will contact the material inside the feeding rack B3 and the feeding rack C4, so that it will not slide. When the limit frame 902 is reset, the push plate structure will push the material to move so that the new standby material moves to the top of the preparation slot 903. A movable plate 803 is installed at the inner end position of the transverse slot 101 through the transverse slot 8 and the spring F802. When the solenoid valve body 6 enters the transverse slot 101, its end just fits the right-angle side position of the triangular limit block A806. At this time, the triangular limit block A806 plays a limiting role on it. After the installation of the solenoid valve stem 601 is completed, the solenoid valve body 6 is slid, and the movable plate 803 will be pushed and at the same time drive the movement of the connecting plate 805. The connecting plate 80 When the triangular limit block A806 moves, the right-angled edge of the triangular limit block B807 at its top pushes the solenoid valve body 6 at the end of the storage chamber 201 to move into the communication chamber 202. During the movement, the solenoid valve body 6 will squeeze the oblique edge of the trapezoidal push block 810, causing the spring G809 to be in a compressed state. When the triangular limit block A806 moves to the end of the transverse groove 8, the inner wall of the end of the transverse groove 8 will squeeze the oblique edge of the triangular limit block A806, causing it to be compressed and lowered to the bottom position of the solenoid valve body 6. At this time, the spring F802 loses its limit and, under the action of its elastic force, horizontally drives the movable plate 803 to reset. The connecting plate 805 also resets at the same time. The triangular limit block B807 is compressed and retracted inside the connecting plate 805, allowing it to pass through the side of the feed rack A2 and then be located in the communication chamber 202. The spring G809 at the top loses its limit, and when it is reset, it will push the solenoid valve body 6 to be assembled inside the communication cavity 202 into the valve stem installation position inside the transverse slot 101, which is convenient for subsequent rapid assembly operations. After the movable plate 803 and the connecting plate 805 are reset in place, the triangular limit block A806 and the triangular limit block B807 are re-expanded under the action of the torsion spring A808, and can be used continuously thereafter. The position of the slot 102 is designed according to the installation position of the feed rack B3, the feed rack C4 and the pneumatic screw gun 7, so that the plug-in plate plays a limiting role on the solenoid valve assembly after being inserted. When the solenoid valve assembly slides along the transverse slot 101 and the end is attached to the plug-in plate, it is ensured that the solenoid valve assembly is aligned with the feed assembly or screw gun position at the corresponding position, which is convenient for rapid processing.A rubber ring 213 is installed inside the bottom ring 212. When no external force is applied, the end of the solenoid valve stem 601 inside the sleeve 205 is aligned with the through-hole 214 and is supported by the rubber ring 213, temporarily positioning it inside the sleeve 205. When the pressure ring 208 presses down on the solenoid valve stem 601, the bottom of the solenoid valve stem 601 squeezes the through-hole 214, expanding the cross groove 215 and allowing the solenoid valve stem 601 assembly to be discharged normally outside the sleeve 205.
