Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve assembly technology, and in particular to a circulating conveyor line for electromagnetic valve assembly. Background Technology

[0002] Solenoid valves, as key actuators in fluid control, are widely used in hydraulics, pneumatics, automotive electronics, precision instruments, and many other industries. Their assembly quality directly determines the accuracy of fluid flow control, sealing performance, and overall service life. In the core assembly process of solenoid valves, the precise combination of the valve core and valve seat is particularly crucial—the valve core must be accurately embedded into the pre-set mounting chamber inside the valve seat to ensure that after subsequent assembly with the coil, the valve core can reciprocate stably along the valve seat axis, thereby achieving reliable fluid control. Any deviation in precision during this process can easily lead to functional failures such as valve core movement jamming and seal failure. With the increasing demand for solenoid valves in the industry, mass production lines have become the mainstream production mode. Currently, mass production lines for solenoid valves generally adopt a layout where conveyor lines connect various processing stations. The loading station (responsible for assembling and positioning the valve seat and valve core) and the welding station (responsible for welding the valve seat-valve core assembly and coil) are respectively located on the conveyor line. The conveyor line needs to accurately transfer the parts to be processed between each station to ensure the smoothness of the continuous production process. However, the solenoid valve itself is small in size, which places extremely high demands on the precision of each link in the production line, especially the alignment accuracy of the valve core and valve seat during loading and the coaxiality accuracy of the components during welding, both of which need to be controlled within the micron range.

[0003] The conveyor lines used in existing mass production lines for solenoid valves are mostly traditional belt conveyors or chain conveyors. The structural design of these conveyors has inherent limitations: on the one hand, the elastic deformation of the belt or chain and the transmission gap during the conveying process can easily cause the parts to be processed to shift laterally or jump vertically, causing the positional deviation of the parts to exceed the allowable range when they are transferred between workstations; on the other hand, traditional conveyor lines lack precise positioning and attitude stabilization mechanisms for small parts, and cannot ensure that the valve seat and valve core maintain the preset spatial attitude when they are transferred to the unloading station, which leads to insufficient loading accuracy. This is manifested in the valve core being difficult to accurately embed into the mounting chamber of the valve seat, requiring manual calibration, which not only reduces production efficiency, but may also further affect the assembly quality due to human operation errors. More importantly, defects in feeding accuracy will directly affect subsequent welding processes: due to positional deviations in the valve seat and valve core components during transportation, it is difficult to ensure coaxiality of the three components when welding them together with the coil, resulting in uneven welds, reduced component bonding strength, and problems such as weld cracking and fluid leakage during subsequent use; at the same time, if the valve core is not assembled along the valve seat axis due to feeding deviations, the reciprocating motion trajectory of the valve core will deviate from the design path after the coil is energized, aggravating component wear and significantly shortening the service life of the solenoid valve.

Long guide rail. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 7 As shown, the circulating conveyor line for assembling an electromagnetic valve according to this utility model includes two long guide rails 4; short straight guide rails 1 are provided at both ends of the long guide rails 4; the short straight guide rails 1 are connected to the two long guide rails 4; a straight push module 102 for pushing a fixture to slide on the short straight guide rail 1 is provided on the short straight guide rail 1; an ejection straight module 101 for pushing the fixture from the short straight guide rail 1 into the long guide rail 4 is provided on the short straight guide rail 1; a fixture actuation mechanism 3 for pushing the fixture to slide on the long guide rail 4 is provided on each of the long guide rails 4; and multiple fixture positioning elements 2 are evenly distributed along the length of the long guide rail 4. Each workstation is equipped with a fixture positioning component 2 for fixing the fixture on the long guide rail 4; the distance between each workstation on the long guide rail 4 is equal, so the distance moved by the fixture actuation mechanism 3 each time is the distance between adjacent workstations; both the ejection linear module 101 and the push linear module 102 are long cylinders; the side walls of the short straight guide rail 1 and the long guide rail 4 have slots for docking; the slots of the long guide rail 4 are aligned with the end faces of the short straight guide rail 1; the push linear module 102 is set in the length direction of the short straight guide rail 1; the slots of the short straight guide rail 1 are aligned with the end faces of the long guide rail 4, and the ejection linear module 101 is set in the length direction of the long guide rail 4. Both the short straight guide rail 1 and the long guide rail 4 are made of two symmetrically arranged "L"-shaped profiles; a straight groove is formed between the two "L"-shaped profiles, and the width of the straight groove matches the width of the fixture; therefore, the fixture can slide on the short straight guide rail 1 and the long guide rail 4; the fixture actuation mechanism 3 pushes each fixture in the long guide rail 4 to move synchronously, so that the fixture moves along the length direction of the long guide rail 4; the fixture actuation mechanism 3 transports the fixtures of each station on the long guide rail 4 to the next station, while the fixtures of the station at the end of the long guide rail 4 are sent into the short straight guide rail 1; the straight push module 102 on the short straight guide rail 1 is used to transport the fixtures on the short straight guide rail 1, while the push-out module 101 pushes the fixtures on the short straight guide rail 1 to another long guide rail 4, completing the transfer of the fixtures between the two long guide rails 4; When the fixture actuation mechanism 3 pushes the fixture on the long guide rail 4 to each station, the fixture positioning component 2 will move to fix the fixture at the corresponding position on the long guide rail 4.

[0017] In this structure, when the fixture is processed at the corresponding position of the long guide rail 4, it is precisely positioned by the fixture positioning part 2. Under the premise of ensuring production efficiency, the accuracy of processing or feeding is improved, ensuring the assembly quality of the solenoid valve and ensuring the service life of the solenoid valve.

[0018] In a preferred embodiment of this utility model, the fixture positioning component 2 includes a positioning fixing seat 201, a positioning card 203, and a positioning telescopic module 202 connected between the positioning card 203 and the positioning fixing seat 201; the inner hole width of the positioning card 203 is equal to the width of the fixture. After the fixture is delivered to its position, the positioning telescopic module 202 drives the positioning card 203 to slide towards the fixture, locking the fixture into the inner hole of the positioning card 203; thus preventing the fixture from sliding on the long guide rail 4 and achieving precise positioning of the fixture; the positioning telescopic module 202 can be a cylinder.

[0019] In a preferred embodiment of this utility model, the positioning telescopic module 202 includes a positioning guide rail 20201 fixed on the positioning base 201, a positioning slider 20202 slidably connected to the positioning guide rail 20201, and a positioning push-out cylinder 20203 with one end fixed to the positioning base 201; the other end of the positioning push-out cylinder 20203 is fixed with a positioning slide plate 20204; the positioning slide plate 20204 is fixedly connected to the positioning slider 20202; each positioning slide plate 20204 is provided with multiple positioning clips 203; The distance between adjacent positioning cards 203 is also equal to the distance between adjacent workstations; a positioning ejection cylinder 20203 drives the positioning slide plate 20204 to slide along the length direction of the positioning guide rail 20201, so as to realize the synchronous sliding of multiple positioning cards 203.

[0020] In a preferred embodiment of this utility model, both inner sidewalls of the inner hole of the positioning card 203 are provided with a chamfered surface 20301; the chamfered surface 20301 is provided at the front end of the inner hole of the positioning card 203 for guiding the insertion of the fixture.

[0021] In a preferred embodiment of the present invention, the fixture actuation mechanism 3 includes a linear actuation assembly and a plurality of actuation elements 303 evenly distributed on the linear actuation assembly; the actuation element 303 is composed of an actuation block 30301, a push block 30302 and a support spring 30303. The top surface of the actuating block 30301 is provided with a notch 3030101; the push block 30302 is hinged inside the notch 3030101; the two ends of the support spring 30303 are respectively fixed on the push block 30302 and the actuating block 30301; a fixed limiting block 3030102 is fixed on the notch 3030101; a movable limiting block 3030202 is provided on the push block 30302; the fixed limiting block 3030102 is located on the swing path of the movable limiting block 3030202; a push block wedge surface 3030201 is provided on the push block 30302; the support spring 30303 pushes the end of the push block 30302 with the push block wedge surface 3030201 from bottom to top into the interior of the long guide rail 4; When the linear actuation assembly moves in the direction of the conveyor line, the support spring 30303 pushes one end of the push block 30302 into the long guide rail 4 and aligns it with the fixture. When the linear actuation assembly pushes the push block 30302 forward, the push block 30302 will not rotate because the fixed limit block 3030102 limits the movable limit block 3030202. Instead, it is supported stably on the fixture and pushes the fixture to slide. When the fixture reaches the work station, the fixture positioning member 2 clamps and fixes the fixture on the long guide rail 4. Then, when the linear actuation assembly resets and moves backward, the fixture will contact the push block wedge surface 3030201 and the fixture will squeeze the push block wedge surface 3030201, causing the push block 30302 to overcome the elastic force of the support spring 30303 and flip downward until the entire push block 30302 is located under the fixture, ensuring that the push block 30302 can reset.

[0022] In a preferred embodiment of this utility model, the linear actuation assembly includes an actuation linear module 301 with one end fixed to a long guide rail 4, a connecting seat 302 fixed to the other end of the actuation linear module 301, and a long rod 304 connected to the connecting seat 302. The movement direction of the actuation linear module 301 is parallel to that of the long guide rail 4. An actuation slider 305 is fixed on the long rod 304. An actuation guide rail 306 is slidably connected to the actuation slider 305. The actuation guide rail 306 is fixedly connected to the long guide rail 4. The actuation block 30301 is fixed on the long rod 304. The actuation linear module 301 is not fundamentally different from existing linear modules, so it will not be described in detail. The actuation linear module 301 drives the connecting seat 302 and the long rod 304 to move, causing multiple actuation elements 303 on the long rod 304 to move synchronously.

[0023] In a preferred embodiment of this utility model, the connecting seat 302 includes a connecting plate 30201 fixed on the toggle linear module 301, a fixing rod 30202 fixed on the connecting plate 30201, and a clamping plate 30203 fixed on the long rod 304; two baffles 3020201 are fixed on the fixing rod 30202; the rod body of the fixing rod 30202 is embedded in the groove of the clamping plate 30203; the two end faces of the clamping plate 30203 are respectively pressed against the two baffles 3020201; The linear module 301 is moved, which drives the connecting plate 30201 to move, causing the long rod 304 to move. The card plate 30203 is a U-shaped card plate. The slot of the U-shaped card plate is inserted into the back of the fixed rod 30202. The connection plate 30201 and the card plate 30203 are positioned by limiting the front and rear of the two baffles 3020201. The assembly direction of the connection plate 30201 and the card plate 30203 is set perpendicular to the sliding direction of the linear actuation module 301. Therefore, the card plate 30203 will not detach from the connection plate 30201.

[0024] In a preferred embodiment of this utility model, the two long guide rails 4 are arranged in parallel to each other.

[0025] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
