Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve processing technology, and in particular to an iron core feeding assembly for an electromagnetic valve. Background Technology

[0002] This invention relates to the field of solenoid valve processing and manufacturing technology, specifically to the assembly and loading stage of the valve core and valve seat in the solenoid valve assembly process. As a key actuator in the field of fluid control, the assembly quality of the solenoid valve directly determines the fluid flow accuracy, sealing performance, and service life. The precise assembly of the valve core and valve seat is one of the core assembly processes. 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, achieving reliable fluid control. In current mass production lines for solenoid valves, the industry still widely relies on the traditional method of manual loading for the combination of valve cores and valve seats. The specific operation process of this method is as follows: First, the valve seat is fixed in the station of a special fixture using a positioning structure, so that the installation cavity of the valve seat faces upward or toward a preset direction; then, the operator holds the valve core and, by visual observation, aligns it with the installation cavity of the valve seat in the fixture, manually adjusting the posture of the valve core (such as axis angle and end face orientation) and insertion position until the valve core is completely placed inside the valve seat and achieves the initial positioning requirements; after the loading of a single valve core is completed, the valve seat and valve core combination operation of the next fixture is carried out, or the coil assembly process is entered. However, the aforementioned manual feeding method has significant technical drawbacks and can no longer meet the demands of large-scale, high-efficiency production of solenoid valves: High labor intensity: Since the processing of solenoid valves is mostly a continuous batch operation, operators need to repeat the single action of "grabbing the valve core - aligning the valve seat - manually positioning" for a long time. In order to avoid misalignment of the valve core and valve seat leading to assembly failure, operators need to maintain a high degree of concentration during operation to control the insertion force and angle. Long-term operation can easily cause hand muscle strain and visual fatigue, which not only increases labor costs, but also increases the risk of operational errors due to personnel fatigue. Low material loading efficiency: The frequency of manual operation is inherently limited. The entire process of grabbing, aligning, and positioning a single valve core usually takes 3-10 seconds, which is difficult to adapt to the continuous operation rhythm of automated production lines. At the same time, the consistency of manual operation is poor. Affected by factors such as operator experience, fatigue level, and concentration, the valve core positioning accuracy fluctuates greatly. About 5%-15% of valve cores need to be reworked and adjusted due to misalignment, which further slows down the overall assembly efficiency. Poor quality stability: Manual positioning makes it difficult to ensure the coaxiality of the valve core and valve seat axis. If there is a slight deviation in the valve core, problems such as valve core jamming and increased movement resistance may occur after subsequent coil assembly, resulting in delayed on / off response of the solenoid valve or sealing failure, reducing the product qualification rate and restricting the technological upgrading and capacity improvement of the solenoid valve processing industry. In summary, the shortcomings of the existing manual feeding method for solenoid valve cores in terms of labor intensity, efficiency, and quality stability have become a key bottleneck hindering the development of solenoid valve processing technology towards automation and high precision. There is an urgent need for a technical solution that can replace manual labor and achieve automatic and precise feeding of valve cores. Utility Model Content

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

[0016] like Figures 1 to 9As shown, the solenoid valve core feeding assembly of this utility model includes a rear feeding conveyor 1 and a loading platform 3. The rear feeding conveyor 1 includes a rear lifting cylinder 101, a rear translation cylinder 102, a rear support 106 fixed on the loading platform 3, a rear translation sliding seat 107 slidably connected to the rear support 106, and a rear lifting sliding seat 103 slidably connected to the rear translation sliding seat 107. The two ends of the rear translation cylinder 102 are respectively fixed to the rear support 106 and the rear translation sliding seat 107. The two ends of the rear lifting cylinder 101 are respectively fixed to the rear lifting sliding seat 103 and the rear translation sliding seat 107. A rear clamping cylinder 104 is fixed on the rear lifting sliding seat 103. A rear clamping plate 105 is fixed on each of the two clamping toes of the rear clamping cylinder 104. The loading platform 3 is equipped with a valve core tray 305 for loading valve cores 5. The valve cores 5 to be loaded are transported to the same vertical plane as the fixture and the rear clamping cylinder 104. The rear translation cylinder 102 drives the rear translation sliding seat 107 to slide on the rear support 106, so that the rear clamping cylinder 104 moves to directly above the valve cores 5 to be loaded. The rear lifting cylinder 101 drives the rear lifting sliding seat 103 and the rear clamping cylinder 104 to move down to the position of the loaded valve cores 5. The rear clamping cylinder 104 drives the two rear clamping plates 105 to clamp and fix the valve cores 5 through the two clamping toes. Then, the valve cores 5 are lowered into the valve seat on the fixture by the cooperation of the rear lifting cylinder 101 and the rear translation cylinder 102.

[0017] This structure enables automatic feeding of the valve core into the valve seat, achieving efficient and precise feeding, reducing labor intensity, and improving feeding accuracy.

[0018] In a preferred embodiment of this utility model, an arc-shaped groove 10501 is provided on the inner surface of the rear clamping plate 105; a positioning strip 10502 is provided in the inner cavity of the arc-shaped groove 10501; the radius of the arc-shaped groove 10501 is equal to the radius of the valve core 5; and a valve core groove 501 penetrating both sides of the valve core 5 is provided in the middle of the valve core 5, which is used for positioning the coil; by embedding the arc-shaped grooves 10501 on both sides into the outer side of the valve core 5, and by inserting the positioning strips 10502 on both sides from both sides of the valve core groove 501, the valve core 5 is positioned on the rear clamping plate 105, making the feeding direction of the valve core 5 more accurate and eliminating the need for rotation on the fixture.

[0019] As a preferred embodiment of this utility model, a transfer module is provided between the rear feeding conveyor robot 1 and the loading platform 3; The transfer module includes an arrangement mechanism 2 and a front loading robot 4; the arrangement mechanism 2 is located between the rear loading conveyor robot 1 and the front loading robot 4. The arranging mechanism 2 comprises a transfer clamping cylinder 203 and a linear vibrator 204; a linear vibration guide rail 201 is arranged on the linear vibrator 204; a support strip 20101 is disposed at the end of the linear vibration guide rail 201; the transfer clamping cylinder 203 is fixed on the material loading table 3; two clamping toes of the transfer clamping cylinder 203 are each fixedly provided with a transfer clamping jaw 202; the two transfer clamping jaws 202 are respectively arranged on two sides of the support strip 20101; The linear vibrator 204 and the linear vibration guide rail 201 used in cooperation with the linear vibrator 204 have no essential difference from the prior art, so they will not be described in detail here; the front loading manipulator 4 is composed of a transverse moving linear module, a longitudinal moving linear module, a lifting linear module and a clamping jaw cylinder, After the transverse moving linear module, the longitudinal moving linear module, the lifting linear module and the clamping jaw cylinder move in coordination, the valve core 5 in the valve core material tray 305 can be taken out and placed at the front end of the linear vibration guide rail 201. The linear vibrator 204 generates vibration to make the valve cores 5 in the linear vibration guide rail 201 move toward the support strip 20101 and be arranged. Since the width of the linear vibration guide rail 201 gradually decreases, the maximum width of the linear vibration guide rail 201 is equal to the diameter of the valve core 5. However, as the valve core 5 is provided with a notch, when the notch is perpendicular to the length direction of the linear vibration guide rail 201, the width of the valve core 5 is the minimum, and the minimum width of the valve core 5 is equal to the width of the linear vibration guide rail 201. Therefore, the valve cores 5 can be arranged in the same direction at the end of the linear vibration guide rail 201, so that the length direction of the notch of one valve core 5 at the end of the linear vibration guide rail 201 is always arranged perpendicular to the length direction of the linear vibration guide rail 201; when the rearmost valve core 5 is conveyed to the support strip 20101, the transfer clamping cylinder 203 drives the transfer clamping jaws 202 to act, and the transfer clamping jaws 202 on both sides clamp and fix the valve core 5 on the support strip 20101, waiting for the rear loading and conveying manipulator 1 to clamp for loading.

Then, the rear feeding conveyor robot 1 takes out the valve cores 5 from the tray 305 one by one and puts them into the valve seat of the fixture. After the valve cores 5 on the tray 305 are removed, the tray linear module 304 drives the tray lifting module 308 to move to directly below the tray clamping module. The tray lifting module 308 rises and catches the empty valve core tray 305 in the tray clamping module. After the tray clamping module releases the valve core tray 305, the tray lifting module 308 descends and, together with the tray linear module 304, transports the empty valve core tray 305 to the tray support module for storage.

[0021] In a preferred embodiment of this utility model, the number of the tray clamping module and the number of the tray lifting module 308 are both two; both the tray clamping module and the tray lifting module 308 are arranged along the movement direction of the tray linear module 304; both tray lifting modules 308 are fixed on the translation slide plate 306; both tray clamping modules are fixed on the loading rack 301; the distance between the two tray clamping modules is a first distance, and the distance between the two tray lifting modules 308 is a second distance; the first distance is equal to the second distance. One of the tray clamping modules is used to place a tray 305 filled with valve cores 5 for preparation, and the other tray clamping module clamps the tray 305 for the rear feeding robot 1 to feed valve cores 5 one by one. When the tray 305 facing the rear feeding robot 1 is emptied, the tray linear module 304 transports the two tray lifting modules 308 to the positions facing the two tray clamping modules respectively. The tray lifting modules 308 rise simultaneously, catching the empty tray 305 and the full tray 305 respectively. Then, through the coordinated movement of the tray lifting module 308 and the tray linear module 304, the full tray 305 is sent to the position of the tray clamping module facing the rear feeding robot 1, and the empty tray 305 is sent to the tray support module. At this time, the valve core material tray 305 above the material tray support module can be taken out to continue preparing materials, while the material tray clamping module that is not directly facing the rear feeding conveyor robot 1 can continue to put the full valve core material tray 305 into the tray for use.

[0022] In a preferred embodiment of this utility model, the material tray clamping module includes telescopic elements symmetrically arranged on both sides of the loading rack 301; the telescopic element comprises a side pressure cylinder 302 and a side pressure plate 303 slidably connected to the loading rack 301; the two ends of the side pressure cylinder 302 are respectively fixed to the loading rack 301 and the side pressure plate 303; when the valve core material tray 305 is lifted to the height position of the side pressure plate 303, the side pressure cylinder 302 drives the side pressure plate 303 to move, and the side pressure plates 303 on both sides clamp and fix the valve core material tray 305.

When the rod of the stop 30703 is pressed against the support seat 30701, the four movable swing blocks 30702 are horizontally positioned, forming a horizontal support for the valve core material plate 305. During the upward movement of the valve core material plate 305, the valve core material plate 305 overcomes the elastic force of the spring and pushes the movable swing block 30702 up and down until the valve core material plate 305 has completely passed through the movable swing block 30702. The movable swing block 30702 is then reset to a horizontal state, forming a horizontal support for the empty valve core material plate 305.

[0024] In a preferred embodiment of this utility model, the bottom surface of the movable swing block 30702 is provided with a chamfered surface 3070201; the chamfered surface 3070201 is in contact with the valve core material tray 305.
