Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0053] The purpose of the present invention is to provide an automated assembly line for electromagnets to solve the problems existing in the above-mentioned prior art and to improve the production efficiency and production quality of electromagnets.

[0054] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] First, if Figure 1 As shown, the electromagnet includes a solenoid 100 , a steel ball 300 , a magnetic core 400 , a magnetic core shaft 500 , a front yoke sleeve 600 and a sealing ring 200 .

In other embodiments, a slat-shaped conveying mechanism can also be provided to achieve the flow of workpieces, and a support portion can be provided on the conveying mechanism to support the workpiece. In other embodiments, an identification sensor can also be provided next to the workstation to identify whether there is a workpiece on the workstation. If there is a workpiece, the control system will perform corresponding actions.

[0058] The magnetic core loading mechanism 1 can load the magnetic core to the magnetic core loading station; when loading the magnetic core, direction detection needs to be performed in advance to ensure that the notch of the steel ball mounting groove on the magnetic core is facing upward. In a specific embodiment, the magnetic core loading mechanism 1 includes a material distribution channel, a flipping mechanism, a first direction detection mechanism, a second direction detection mechanism, a double clamping mechanism and a magnetic core cache tray; a plurality of magnetic cores are placed horizontally on the magnetic core cache tray, and the material distribution channel is used to separate the materials stored in the magnetic core cache tray separately, and push the magnetic core in the horizontal state to the flipping station of the flipping mechanism; the flipping mechanism is used to flip the posture of the magnetic core 90° to a vertical state, which is convenient for detecting the direction of the magnetic core; the first direction detection mechanism and the second direction detection mechanism are used to detect the front and back and angle of the incoming magnetic core, and adjust its front and back and angle to the correct loading posture, so that the double clamping mechanism can clamp it to the turntable and position it.

[0059] The steel ball feeding mechanism 2 is used to install steel balls into the magnetic core on the steel ball feeding station; the steel balls are installed in the steel ball installation grooves of the magnetic core; the steel ball installation grooves extend along the axial direction of the magnetic core and are arranged on the surface of the shaft core, and are provided in plurality. In the specific embodiment of the present invention, five steel ball installation grooves are provided. The steel balls slide into the steel ball installation grooves from the top openings of the steel ball installation grooves. The side openings of the steel ball installation grooves are smaller than the diameter of the steel balls, thereby preventing the steel balls from sliding out of the side openings after being installed.

[0060] Specifically, the steel ball feeding mechanism 2 includes a steel ball ejecting mechanism, a steel ball storage chamber 202 and a vacuum adsorption mechanism. A plurality of steel balls are stored in the steel ball storage chamber 202. The steel ball ejecting mechanism can sink to be immersed under the steel balls. The top of the steel ball ejecting mechanism is provided with grooves having the same number as the steel ball mounting grooves. Each groove can accommodate a steel ball. When loading is required, the steel ball ejecting mechanism rises and ejects a plurality of steel balls at a time. The vacuum adsorption mechanism vacuum adsorbs the ejected steel balls and transfers them to the top of the magnetic core. The steel ball ejecting mechanism can be composed of five ejector rods 201, and the grooves are provided on the tops of the ejector rods 201. Figure 3 As shown, a plurality of sliding holes are provided at the bottom of the steel ball storage chamber 202, and a push rod 201 corresponds to a sliding hole. The push rod 201 can be slidably provided in the sliding hole. A push rod 201 driving device for driving the push rod 201 to move up and down is provided at the bottom of the push rod 201. The push rod 201 driving device can be electrically driven or hydraulically driven.

[0061] In addition, due to the small size of the steel ball, in order to achieve accurate delivery of the steel ball, a movable guide flow channel is also provided. The guide flow channel has a trumpet-shaped structure and can be moved to the top of the magnetic core. The lower end opening of the guide flow channel is connected to the steel ball mounting groove of the magnetic core, and the upper end opening is larger than the lower end opening. After the vacuum adsorption mechanism moves into place, the vacuum is broken and air is blown to make the steel ball flow from the guide flow channel to the steel ball mounting groove. The guide flow channel is driven up and down by the cylinder. The guide flow channel can be moved down to the lower end opening to be connected to the steel ball mounting groove of the magnetic core, and can also be moved up to away from the magnetic core to facilitate the flow of the magnetic core to the next station. Specifically, Figure 6 and Figure 7 As shown, the vacuum adsorption mechanism includes multiple vacuum pipes 203, the bottom of the vacuum pipes 203 is used to adsorb the steel ball, and a buffer spring 204 is also provided at the vacuum pipes 203 to ensure elastic contact between the end of the vacuum pipes 203 and the top of the push rod 201.

[0062] In some embodiments, in order to limit the position of the steel ball, the first riveting mechanism 3 rivets the top edge of the steel ball installation groove on the magnetic core at the first riveting station until it is deformed so that the deformed portion can limit the steel ball in the steel ball installation groove;

[0063] The first riveting mechanism 3 includes a first riveting press and a pressing head. The first riveting press can drive the pressing head to press down and rivet the top edge of the steel ball installation groove until it is deformed so that the deformed portion can confine the steel ball in the steel ball installation groove. The shape of the pressing head is determined by the shape of the top of the steel ball installation groove. In other embodiments, a pressing head brushing assembly can be provided on one side of the first riveting mechanism 3 to brush the bottom of the pressing head after riveting to prevent impurities thereon from adversely affecting the next round of closing.

[0064] The magnetic core shaft installation mechanism 6 is used to install the magnetic core shaft into the axial hole of the magnetic core on the magnetic core shaft installation station; in some embodiments, the magnetic core shaft installation mechanism 6 includes a vibration feeding mechanism, a blowing mechanism and a positioning station, the vibration feeding mechanism is used to vibrate the output magnetic core shaft to one side of the blowing channel, the blowing mechanism blows the magnetic core shaft through the blowing channel to the positioning station, and the positioning station can place the magnetic core shaft vertically when receiving the magnetic core shaft; the magnetic core shaft installation mechanism 6 uses a gripper to clamp the magnetic core shaft on the positioning station and transfer it to be installed in the axial hole of the magnetic core. The magnetic core shafts discharged from the vibrating feeding mechanism are generally placed horizontally. Therefore, the blowing mechanism is used to blow the horizontally placed magnetic core shafts to the positioning station. The positioning station can be a vertical slot. When the magnetic core shaft enters the vertical slot, it changes from a horizontal state to a vertical state, so that the gripper can grab the magnetic core shaft in a specific state from a specific position, and the operation time of the gripper can be shortened. That is, the vibrating feeding mechanism, the blowing mechanism and the gripper transfer and install different magnetic core shafts in an orderly or simultaneous manner under the control of the control system, thereby improving the production efficiency of the electromagnet. Before the magnetic core shaft installation mechanism 6 installs the magnetic core shaft, it is necessary to flip the magnetic core equipped with the steel ball through a flipping mechanism to facilitate the insertion of the magnetic core shaft into the back shaft hole of the magnetic core.

[0065] The second riveting mechanism 7 is used to rivet the edge of the shaft hole of the magnetic core on the second riveting station until it is deformed and pressed against the outer wall of the magnetic core shaft; after the magnetic core shaft is installed in the shaft hole, the top end of the magnetic core shaft extends out of the shaft hole. This is determined by the structure of the electromagnet. In order to fix the magnetic core shaft in the shaft hole, the second riveting mechanism 7 is used to rivet the top edge of the inner wall of the shaft hole, so that the edge is deformed and has a pressing effect on the magnetic core shaft.

[0066] The solenoid loading mechanism 8 is used to load the solenoids to the solenoid loading station. In a specific embodiment, the solenoid loading mechanism 8 uses a gripper to grab the solenoids and send them to the solenoid loading station. The solenoids are pre-stored on a solenoid storage tray, which is provided with a plurality of storage locations. Each storage location can hold a solenoid or a finished workpiece. That is, after the finished product is manufactured, the solenoid storage tray also performs preliminary storage of the finished product. The solenoid storage tray is mounted on the top of a mobile trolley to facilitate the transportation of the solenoids and the finished product. The mobile trolley can be limited to a specific position by a limit bracket to facilitate the gripper to grab the solenoid. In other embodiments, the solenoids can also be loaded by any solenoid loading mechanism 8 in the prior art.

[0067] The core installation mechanism 9 is used to install the core with the core shaft and the steel ball installed in the solenoid on the core installation station; specifically, the core installation mechanism 9 uses a gripper to install the core with the core shaft and the steel ball installed in the solenoid.

[0068] The front yoke sleeve loading mechanism 10 is used to load the front yoke sleeve to the top of the solenoid on the front yoke sleeve loading station and pre-press it; in a specific embodiment, the front yoke sleeve loading mechanism 10 can use a gripper to load and pre-press the front yoke sleeve, and because the gripper cannot exert excessive pressure on the front yoke sleeve, a front yoke sleeve clamping mechanism 11 is subsequently provided, and the front yoke sleeve clamping mechanism 11 is used to press the front yoke sleeve on the front yoke sleeve pressing station and pre-pressed on the top of the solenoid onto the solenoid; the front yoke sleeve clamping mechanism 11 uses a press to clamp the front yoke sleeve, and the front yoke sleeve clamping mechanism 11 can also output the clamping force and the displacement during downward pressing to the control system, and the control system determines whether the downward pressing is in place based on the clamping force and the downward pressing displacement.

[0069] The sealing ring installation mechanism 13 is used to install the sealing ring in the sealing ring installation groove; the sealing ring installation mechanism 13 also uses a gripper to grab the sealing ring and install it. Before installation, the sealing ring needs to be stretched in advance to facilitate the subsequent installation process.

[0070] Control system: The control system controls the above-mentioned mechanisms to work in an orderly manner. The control system is a computer terminal or other intelligent control terminal.

[0071] In some embodiments, such as Figure 4 As shown, it also includes a closing station arranged between the first riveting station and the magnetic core shaft installation station and a closing mechanism 4 arranged on one side of the closing station. The closing mechanism 4 presses the part of the structure that is deformed to the outer edge of the magnetic core during riveting inward to achieve closing; after the first riveting mechanism 3 rivetes, there is a certain probability that the material on the top of the magnetic core will be riveted and deformed to the outer edge of the magnetic core, which will affect the appearance and even affect the subsequent assembly with the solenoid. Therefore, the closing mechanism 4 is used to close the part with larger deformation, and squeeze the deformed part inward and downward to reduce the influence of the deformed part on the appearance of the magnetic core and the assembly process.

[0072] Specifically, the closing mechanism 4 includes a closing press and a closing sleeve 401, such as Figure 5 As shown, the closing sleeve 401 has a trumpet-shaped structure that is larger at the bottom and smaller at the top. The closing press can drive the closing sleeve 401 to press the part of the structure that is deformed to the outer edge of the magnetic core during riveting inward to achieve closing. When pressed down, the closing sleeve 401 is coaxial with the magnetic core and is sleeved on the top of the magnetic core. The inner wall of the closing sleeve 401 has the effect of squeezing the deformed part.

[0073] In other embodiments, a fault detection station and a steel ball detection mechanism 5 are further included, which are arranged after the closing station and before the magnetic core shaft installation station. The steel ball detection mechanism 5 is used to detect whether there is and only one steel ball in the steel ball installation groove; specifically, the steel ball detection mechanism 5 uses a gripper to clamp the magnetic core and flip it to detect whether the steel ball can be confined in the steel ball installation groove, and uses a dust removal mechanism to remove dust from the magnetic core during flipping; Figure 8 As shown, the steel ball detection mechanism 5 can also use a probe 501 inserted into the steel ball installation slot to detect whether there is one and only one steel ball. If there are multiple steel balls or no steel balls in the steel ball installation slot, the steel ball detection mechanism 5 will flash or light up a fault light to alert the staff. After the steel ball detection mechanism 5 has completed the inspection and the magnetic cores with no faults are returned to the work station on the turntable, so that the magnetic core installation mechanism 9 can use the gripper to grab the magnetic cores with no faults. The magnetic cores with faults are transported to the defective area by the defective conveyor belt.

[0074] In other embodiments, an airtightness detection station and an airtightness detection mechanism 14 are further included, and the airtightness detection device performs airtightness detection on the workpiece assembled with the sealing ring; preferably, a plurality of airtightness detection mechanisms 14 are provided, and the plurality of airtightness detection mechanisms 14 take turns to receive the workpiece assembled with the sealing ring; when a plurality of airtightness detection mechanisms 14 are provided, the plurality of airtightness detection mechanisms 14 can slide or rotate to the sealing ring receiving station to facilitate the fixed-point transfer of the sealing ring by the gripper, and after the airtightness detection mechanism 14 receives the sealing ring, it can slide down or rotate to other positions for airtightness detection, and the airtightness detection mechanism 14 can adopt the mechanism in the prior art.

[0075] In other embodiments, a laser coding station and a laser coding mechanism are also included. The laser coding mechanism is used to laser code the workpiece. After coding, the finished product can be grabbed by a gripper and transported off the line to the solenoid storage disk for initial storage.

[0076] In other embodiments, an oil spraying station and an oil spraying mechanism 12 are further included, which are arranged after the solenoid loading station and before the front yoke sleeve loading station. The oil spraying mechanism 12 is used to spray oil onto the metal surface of the outer wall of the solenoid to prevent corrosion of the metal surface.

[0077] In other embodiments, after the magnetic core shaft is installed, a dust removal mechanism and a magnetic core shaft detection mechanism may be provided in sequence. The dust removal mechanism is used to blow air to remove dust from the components after the magnetic core shaft is installed. The magnetic core shaft detection mechanism is used to detect whether the magnetic core shaft is installed in place. The magnetic core shaft detection mechanism specifically detects whether it is in place by detecting the height of the magnetic core shaft. If the magnetic core shaft is too high or too low, it is an incorrect assembly and needs to be grabbed by a gripper and output to a defective product conveyor belt.

[0078] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
