Description

[0001] The invention relates to the technical field of assembly equipment, in particular to solenoid valve assembly equipment. Background Art

[0002] Solenoid valve is an industrial device controlled by electromagnetics. It is an actuator and a basic component for controlling fluid automation, not limited to hydraulic and pneumatic systems. At present, various automation equipment is commonly used in the assembly of solenoid valves, such as automatic assembly machines for solenoid valve diaphragms.

[0003] Prior art, a patent with a patent authorization announcement number of CN112318111B, discloses an automatic assembly device for medical diaphragm solenoid valves, comprising: a rotating table, with six installation stations evenly distributed on the top of the rotating part; a fixing fixture, with a working end arranged on the installation station radially outward along the rotating table, and the fixing fixture is provided with a first clamping block and a second clamping block; an elastic positioning fixture, which is arranged at the top of the fixing fixture and has a semicircular fixing block and a semicircular positioning block at its working end, and the semicircular positioning block is coaxially located on the top of the semicircular fixing block; a driving part feeding mechanism, an abutment cylinder feeding mechanism, a diaphragm feeding mechanism, an air-passing part feeding mechanism, an air-passing part abutting fixing mechanism and a belt conveyor, and the mechanisms are evenly distributed on the outside of the stations in sequence. The equipment can automatically assemble diaphragm solenoid valves with high working efficiency and precision.

[0004] Although the assembly equipment in the above patent can automatically assemble diaphragm solenoid valves with high working efficiency and precision, the assembly equipment still has certain defects. In order to improve the assembly efficiency, most of the current assembly equipment will set a turntable in the middle position of the equipment, and let the various mechanisms in the equipment be distributed around the turntable. In order to reduce the space occupied, the diameter of the turntable is limited and the gap between the various mechanisms is small. Therefore, when the assembly equipment is damaged, the maintenance personnel can only perform maintenance work in a small space, which is extremely inconvenient. Therefore, the existing assembly equipment needs to be improved. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a solenoid valve assembly device to solve the problems raised by the background technology and make the equipment more convenient to inspect and maintain.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an electromagnetic valve assembly device, comprising a base, a rotating table is installed on the base, a control system is installed on one side of the top of the base, a discharge guide plate fixed to the base is provided on one side of the rotating table, a connecting column is fixed to one side of the top of the base, the top of the connecting column is rotatably connected to a top plate, the bottom of the top plate away from one end of the connecting column is fixed to a support assembly, the top of the top plate is fixed to a cylinder, a connecting ring is provided at the bottom of the top plate, the connecting ring is fixed to the output end of the cylinder, the bottom of the connecting ring is rotatably connected to a rotating ring, the bottom of the rotating ring is slidably connected to multiple mounting plates, and an extrapolation assembly is provided in the middle of the multiple mounting plates.

[0007] Furthermore, the support assembly includes a support column, a fixed block and a universal wheel. The top of the support column is fixedly connected to the bottom of the top plate away from one end of the connecting column, the fixed block is rotatably connected to the lower end of the support column, the top of the universal wheel is rotatably connected to the bottom of the support column, and a fixing groove matching the fixed block is provided at one end of the top of the base away from the connecting column.

[0008] Furthermore, a wiring groove is provided at the top of the connecting ring, and three rotating grooves with equal angles are provided at the bottom of the wiring groove. A rotating block is slidably connected to the middle position of the rotating groove, and the bottom of the rotating block is fixedly connected to the top of the rotating ring. A plurality of slots connected to the wiring groove are provided on the outer side of the connecting ring, and the number of the slots matches the number of mounting plates.

[0009] Furthermore, a slide groove is provided in the middle position of the mounting plate, a positioning column is fixedly connected to the inside of the slide groove, a slider matching the slide groove is slidably connected to the positioning column, the slider is fixedly connected to the bottom of the rotating ring, an elastic member is sleeved on the end of the positioning column away from the slider, one end of the elastic member is fixedly connected to the end of the slide groove, and the other end of the elastic member is fixedly connected to the slider.

[0010] Furthermore, the push-out assembly includes a wedge block and an extrusion ring, the top of the extrusion ring is fixedly connected to the bottom of the top plate, the wedge block is fixedly connected to one end of the mounting plate, and the outer wall of the extrusion ring and the inner wall of the wedge block are both inclined.

[0011] Furthermore, a dustproof top cover is provided on the top of the connecting ring, the top of the dustproof top cover is fixedly connected to the bottom of the top plate, the outer wall of the dustproof top cover is fixedly connected to a plurality of equally distributed card blocks, the number of the card blocks matches the number of the mounting plates, and a card slot is provided on the top of the mounting plate away from one end of the extrusion ring, and the card slot matches the card block.

[0012] Furthermore, the block is U-shaped, and the sides of the bottom of the block are chamfered.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. For this type of solenoid valve assembly equipment, when it is necessary to perform maintenance and repair on the equipment, it is only necessary to take out the fixing block from the fixing slot, and then push the top plate to rotate through the support column, so that the various mechanisms fixed on the mounting plate in the equipment can be staggered with the turntable, so that there is more space outside the various mechanisms and the turntable, which is convenient for maintenance personnel to perform maintenance.

[0015] 2. For this type of solenoid valve assembly equipment, after the top plate is turned open, the cylinder can drive the connecting ring and the rotating ring to descend. During the descent process, the push-out assembly will push the mounting plate outward, making the spacing between adjacent mounting plates larger, further increasing the gap between each mechanism to facilitate maintenance personnel to maintain and repair the equipment.

[0016] 3. For this type of solenoid valve assembly equipment, after the equipment maintenance is completed, the cylinder will drive the connecting ring and the rotating ring to rise. During the rise, the card block will gradually insert into the card slot on the mounting plate, thereby limiting the positioning of the mounting plate to prevent the position of the mounting plate from changing, causing the mechanism to be unable to align with the work station on the rotating table.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figures 1 to 9 A solenoid valve assembly device includes a base 1, a rotating table 2 is installed on the base 1, a control system 3 is installed on one side of the top of the base 1, a discharge guide plate 4 fixed to the base 1 is provided on one side of the rotating table 2, a connecting column 6 is fixed to one side of the top of the base 1, a top plate 7 is rotatably connected to the top of the connecting column 6, a supporting assembly is fixed to the bottom of the top plate 7 away from one end of the connecting column 6, a cylinder 11 is fixed to the top of the top plate 7, a connecting ring 12 is provided at the bottom of the top plate 7, the connecting ring 12 is fixed to the output end of the cylinder 11, a rotating ring 17 is connected to the bottom of the connecting ring 12, a plurality of mounting plates 19 are connected to the bottom of the rotating ring 17, and an extrapolation assembly is provided in the middle of the plurality of mounting plates 19.

[0029] The solenoid valve assembly device of the present invention only needs to open the support assembly when the device needs to be repaired, and then push the top plate 7, and the top plate 7 will rotate with the connecting column 6 as the axis. Since the various mechanisms on the upper end of the device (such as: feeding and transporting mechanism, positioning mechanism, pressing mechanism, detection mechanism and unloading mechanism) are respectively installed on various mounting plates 19, the mounting plates 19 are slidably connected to the rotating ring 17, the rotating ring 17 is rotatably connected to the connecting ring 12, and the connecting ring 12 is connected to the top plate 7 as a whole through the cylinder 11. Therefore, when the top plate 7 moves, the rotating ring 17 is located at the rotating ring 17. The various mechanisms at the bottom of the moving ring 17 (such as the loading and transporting mechanism, the positioning mechanism, the pressing mechanism, the detecting mechanism and the unloading mechanism) will move together with the top plate 7. When the top plate 7 is rotated to one side of the base 1, the various mechanisms at the upper end of the device (such as the loading and transporting mechanism, the positioning mechanism, the pressing mechanism, the detecting mechanism and the unloading mechanism) will be staggered with the rotating table 2, so that a large space is exposed below the various mechanisms (such as the loading and transporting mechanism, the positioning mechanism, the pressing mechanism, the detecting mechanism and the unloading mechanism) and above the rotating table 2, so that maintenance personnel can easily inspect the various mechanisms or the rotating table 2. The turntable 2 is maintained and repaired, and the cylinder 11 is electrically connected to the control system 3 and controlled by the control system 3. The end of the external conveying and loading mechanism 28 is fixed on the base 1. Since the external conveying and loading mechanism 28 (a mechanism outside the equipment for conveying materials to the inside of the equipment), the loading and transfer mechanism (a mechanism for transferring materials on the external conveying and loading mechanism 28 to the turntable 2), the positioning mechanism (a mechanism for accurately positioning the diaphragm and other components to ensure accurate docking during the assembly process), the pressing mechanism (a mechanism responsible for pressing the various components together to ensure sealing and firmness), the detection mechanism (a mechanism for real-time monitoring of assembly quality, checking whether the components are correctly installed and whether the functions are normal) and the unloading mechanism (a mechanism for removing the finished product from the turntable 2) are all existing mature products, so they will not be described in detail here. In addition, the structures of the base 1, the turntable 2 and the control system 3 in the present invention are similar to the prior art, and the patent authorization announcement number is CN112318111B, which discloses a medical diaphragm type solenoid valve automatic assembly equipment structure, so it will not be elaborated on here.

[0030] As a preferred technical solution of the present invention, the support assembly includes a support column 8, a fixed block 9 and a universal wheel 10. The top of the support column 8 is fixedly connected to the bottom of the top plate 7 away from the connecting column 6. The fixed block 9 is rotatably connected to the lower end of the support column 8. The top of the universal wheel 10 is rotatably connected to the bottom of the support column 8. A fixing groove 5 matching the fixing block 9 is provided at the end of the top of the base 1 away from the connecting column 6.

[0031] Specifically, when the equipment is working normally, the fixing block 9 is inserted in the fixing groove 5, thereby restricting the top plate 7 to prevent the top plate 7 from rotating, causing the various mechanisms to be misaligned and affecting the normal operation of the equipment; during maintenance and overhaul, the fixing block 9 can be removed from the fixing groove 5, and then the support column 8 can be pushed to drive the top plate 7 to move, so as to facilitate the misalignment of the various mechanisms and the rotating table 2.

[0032] As a preferred technical solution of the present invention, a wiring groove 14 is provided at the top of the connecting ring 12, and three rotating grooves 13 with equal angles are provided at the bottom of the wiring groove 14. A rotating block 16 is slidably connected to the middle position of the rotating groove 13, and the bottom of the rotating block 16 is fixedly connected to the top of the rotating ring 17. A plurality of slots 15 connected to the wiring groove 14 are provided on the outer side of the connecting ring 12, and the number of the slots 15 matches the number of the mounting plates 19.

[0033] Specifically, the connecting wires of each mechanism can enter the wiring groove 14 through the slot 15, which can not only prevent the connecting wires from being damaged, but also make the connection guide more neat, which is convenient for maintenance personnel to find and repair. In addition, since the top plate 7 rotates with the connecting column 6 as the axis, some individual mounting plates 19 will be closer to the connecting column 6, resulting in a lack of sufficient space near some mechanisms for maintenance work. At this time, the rotating ring 17 can be turned to rotate the rotating ring 17 to a certain angle, so that some mechanisms can be moved away from the connecting column 6.

[0034] As a preferred technical solution of the present invention, a slide groove 20 is opened in the middle position of the mounting plate 19, and a positioning column 21 is fixedly connected to the inside of the slide groove 20. A slider 18 matching the slide groove 20 is slidably connected to the positioning column 21. The slider 18 is fixedly connected to the bottom of the rotating ring 17. An elastic member 22 is sleeved on one end of the positioning column 21 away from the slider 18. One end of the elastic member 22 is fixedly connected to the end of the slide groove 20, and the other end of the elastic member 22 is fixedly connected to the slider 18.

[0035] As a preferred technical solution of the present invention, the push-out assembly includes a wedge block 23 and an extrusion ring 24, the top of the extrusion ring 24 is fixedly connected to the bottom of the top plate 7, the wedge block 23 is fixedly connected to one end of the mounting plate 19, and the outer wall of the extrusion ring 24 and the inner wall of the wedge block 23 are both inclined.

[0036] Specifically, during maintenance, the cylinder 11 can be used to drive the connecting ring 12 and the rotating ring 17 to descend, thereby lowering the height of each mechanism to facilitate maintenance personnel to perform maintenance. When the connecting ring 12 and the rotating ring 17 driven by the cylinder 11 descend, the extrusion ring 24 will contact the wedge block 23. Since the outer wall of the extrusion ring 24 and the inner wall of the wedge block 23 are both inclined, the wedge block 23 will be squeezed and pushed outward by the extrusion ring 24. When the wedge block 23 moves outward, it will drive the mounting plate 19 to move outward together, further expanding the distance between the various mechanisms, thereby increasing the maintenance space.

[0037] As a preferred technical solution of the present invention, a dustproof top cover 27 is provided on the top of the connecting ring 12, and the top of the dustproof top cover 27 is fixedly connected to the bottom of the top plate 7. The outer wall of the dustproof top cover 27 is fixedly connected to a plurality of equally distributed blocks 26, and the number of the blocks 26 matches the number of the mounting plates 19. A slot 25 is provided on the top of the mounting plate 19 away from the extrusion ring 24, and the slot 25 matches the block 26.

[0038] As a preferred technical solution of the present invention, the block 26 is U-shaped, and the sides of the bottom of the block 26 are chamfered.

[0039] Specifically, after the inspection is completed, the cylinder 11 will drive the connecting ring 12 and the rotating ring 17 to move upward. During the upward movement of the rotating ring 17, the wedge block 23 will be separated from the extrusion ring 24. Under the action of the elastic member 22, the mounting plate 19 will be pushed back to its original position. When the connecting ring 12 moves back to its original position, the clamping block 26 will be inserted into the clamping groove 25 at the top of the mounting plate 19. Since the sides of the bottom of the clamping block 26 are chamfered and have a certain guiding effect, the position of the mounting plate 19 will be pushed by the clamping block 26, making it easier for the mounting plate 19 to return to its original position (this position refers to the position before the equipment is inspected) to avoid the situation where the mechanism cannot match the work station.

[0040] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
