[0002] As an important fluid control component, the solenoid valve is widely used in various industries. In the production process of the solenoid valve, its processes are numerous and scattered. For example, it is necessary to insert pins into the solenoid valve skeleton (insert PIN pins into the pre - holes of the solenoid valve skeleton), wind coils (wind electromagnetic coils around the solenoid valve skeleton), dip in tin (dip the pins of the solenoid valve into high - temperature molten tin), cut the feet (cut off the redundant or too long pin parts), and also perform operations such as resistance testing, withstand voltage testing, and appearance inspection on the solenoid valve. In the prior art, the solenoid valve is mainly produced in the mode of manual flow production or the combination of manual and semi - automatic equipment, which requires a large number of operators, has a low production efficiency, and cannot meet the large - batch production requirements; moreover, some processes with high precision requirements completely depend on the production experience of the operators, resulting in the inability to guarantee the production quality of the products.

The structure of the solenoid valve skeleton 60 refers to Figure 2 .

[0034] Among them, the first feeding device 1 is used to load the solenoid valve skeleton 60 onto the pin inserting machine 2; on one side of the second feeding device 3, the winding machine 4, and the soldering machine 5, there is a transfer vehicle device 9. The transfer vehicle device 9 includes a front transfer mechanism 91, a link bridge 92, and a rear transfer mechanism 93 that are sequentially connected in the X-axis direction. A plurality of first transfer fixtures 40 that match the number of winding shafts of the winding machine 4 are installed on both the front transfer mechanism 91 and the rear transfer mechanism 93. The first transfer fixture 40 is used to fix the solenoid valve skeleton 60. The second feeding device 3 is used to load the pin-inserted solenoid valve skeleton 60 discharged from the pin inserting machine 2 onto the first transfer fixture 40 on the front transfer mechanism 91, and then transfer it to the winding machine 4 through the front transfer mechanism 91. The first transfer fixture 40 on the rear transfer mechanism 93 is used to transfer the wound solenoid valve skeleton 60 discharged from the winding machine 4 to the soldering machine 5; on the discharging side of the soldering machine 5, there is a discharging device 10. The discharging device 10 is used to transfer the soldered solenoid valve skeleton 60 on the soldering machine 5 to the tray loading machine 8; the lead trimming assembly 6 and the testing and detecting assembly 7 are sequentially arranged at intervals beside the discharging device 10.

[0035] Specifically, the first feeding device 1 includes a first vibrating disk and a first linear vibrating track. One end of the first linear vibrating track is connected to the discharge port of the first vibrating disk, and the other end is connected to the pin inserting station of the pin inserting machine 2. The first vibrating disk is used to apply horizontal vibration to achieve automatic conveying of the solenoid valve skeleton 60, and the first linear vibrating track is responsible for guiding the solenoid valve skeleton 60 into the pin inserting position of the pin inserting machine 2.

[0036] The pin inserting machine 2 is an existing technology in this field. For example, Chinese patent document CN213070899U discloses an assembly line for solenoid valve skeletons 60, which includes a full-automatic skeleton pin inserting machine. The full-automatic skeleton pin inserting machine is provided with a skeleton automatic feeding device, a first material transfer device, a pin automatic feeding device, a pin inserting device, a final insertion device, a trimming device, a missing pin detection device, a missing pin NG sorting device, a rotating device, a first conveying device, and a first control device. The pin inserting device includes a pin clamping mechanism and a pin inserting mechanism. The pin clamping mechanism can clamp the PIN pins, and then the pin inserting mechanism can send the PIN pins to and pre-insert them into the solenoid valve skeleton 60. The full-automatic skeleton pin inserting machine can realize the PIN pin insertion of the solenoid valve skeleton 60. Of course, the above structure of the pin inserting machine is exemplary rather than restrictive.

[0037] Reference Figure 3, the second feeding device 3 includes a second vibrating disk 31, a second linear vibrating track 32 and a transfer loading mechanism 33. One end of the second linear vibrating track 32 is connected to the discharge port of the second vibrating disk 31, and the other end is close to the transfer loading mechanism 33. The solenoid valve skeletons 60 that have completed pin insertion on the pin insertion machine 2 automatically flow into the second vibrating disk 31, and the second linear vibrating track 32 guides the solenoid valve skeletons 60 into the picking position of the transfer loading mechanism 33; the transfer loading mechanism 33 includes a gripper loading module 331, and the gripper loading module 331 is used to pick up the solenoid valve skeletons 60 at the picking position and place them on the first transfer fixture 40 of the front-stage transfer mechanism 91.

[0038] Reference Figure 4 , both the front-stage transfer mechanism 91 and the rear-stage transfer mechanism 93 include a transfer bracket 20 and a first X-axis moving linear module 30. The first X-axis moving linear module 30 is installed on the transfer bracket 20, and the first X-axis moving linear module 30 is a synchronous belt drive linear module. The first transfer fixture 40 is fixedly connected to the slider of the first X-axis moving linear module 30.

For example, Chinese patent document CN217588579U discloses a solenoid valve coil and its winding machine, which includes a winding machine. The winding machine includes a frame and a number of main rotating shafts. The main rotating shafts are all installed on the frame side by side, and a driving device A is installed on the frame. The driving device A is connected to all the main rotating shafts to drive all the main rotating shafts to rotate synchronously. This winding machine can wind the solenoid valve skeletons 60. Of course, the above structure of the winding machine is exemplary rather than restrictive.

[0040] Reference Figures 5 - 6 , the soldering machine 5 includes a soldering transfer mechanism 51, a pin leveling component 52, a soldering flux component 53 and a soldering mechanism 54. The pin leveling component 52, the soldering flux component 53, the soldering mechanism 54 and the soldering component are sequentially arranged at intervals below the soldering transfer mechanism 51, where:

[0041] The tinning transfer mechanism 51 includes a first Y-axis motion linear module 511, a first Z-axis motion linear module 512 and a rotating module 513. The first Y-axis motion linear module 511 is installed on the side of the rear-stage transfer mechanism 93 through multiple support frames. The first Z-axis motion linear module 512 is installed as a whole on the first Y-axis motion linear module 511, and is fixedly connected to the slider of the first Y-axis motion linear module 511. The rotating module 513 is installed as a whole on the first Z-axis motion linear module 512, and is fixedly connected to the slider of the first Z-axis motion linear module 512. A plurality of second transfer jigs 50 matching the number of the first transfer jigs 40 are installed on the rotating module 513. The first Y-axis motion linear module 511 is used to drive the first Z-axis motion linear module 512 and the rotating module 513 to translate along the Y-axis, so as to facilitate the first transfer fixture 40 to transfer the solenoid valve skeleton 60 to the second transfer fixture 50; and the first Z-axis motion linear module 512 is used to drive the rotating module 513 to translate up and down along the Z-axis, and the rotating module 513 is used to drive the second transfer fixture 50 to rotate on the XY plane.

[0042] Optionally, the first transfer jig 40 and the second transfer jig 50 both include an elastic plug connector, which matches the inner cavity of the solenoid valve skeleton 60 and is used to be inserted into the inner cavity of the solenoid valve skeleton 60. The front end of the elastic plug connector is conical and has an opening and closing seam. The opening and closing seam is open in a normal state and is closed when the elastic plug connector is inserted into the inner cavity of the solenoid valve skeleton 60, so that the elastic plug connector is tightly inserted into the inner cavity of the solenoid valve skeleton 60 to fix the solenoid valve skeleton 60.

[0043] refer to Figure 6 Optionally, the rotating module 513 includes a rotating servo motor, a base plate and a plurality of rotating shafts; the plurality of rotating shafts are arranged at intervals and match the number of the first transfer fixture 40, the plurality of rotating shafts penetrate the base plate and are connected to the base plate through bearings, one end of the rotating shaft is coaxially fixedly connected to the second transfer fixture 50, the other end of the rotating shaft is coaxially fixedly connected to two passive synchronous pulleys, the output shaft of the servo motor is provided with an active synchronous pulley, the active synchronous pulley is connected to the passive synchronous pulley through a synchronous belt transmission, and the left and right adjacent passive synchronous pulleys are connected through a synchronous belt transmission. The servo motor is used to drive the plurality of rotating shafts to rotate simultaneously, so as to drive the second transfer fixture 50 and the electromagnetic valve frame 60 to rotate in the XZ plane.

[0044] refer to Figure 7, the pin flattening assembly 52 includes a flattening bracket 521, a flattening plate 522 and a strengthening block 523. The flattening bracket 521 is vertically fixed below the solder dipping transfer mechanism 51. The flattening plate 522 is fixedly connected to the top of the flattening bracket 521 along the X-axis direction. The strengthening blocks 523 are arranged below both ends of the flattening plate 522 and are fixedly connected to the flattening bracket 521. The flattening plate 522 and the strengthening blocks 523 are connected by connecting bolts, and the strengthening blocks 523 are provided with strengthening bolts for abutting against the bottom of the flattening plate 522. The solder dipping transfer mechanism 51 moves the solenoid valve skeleton 60 above the pin flattening assembly 52, and the flattening plate 522 can flatten the pins of the solenoid valve skeleton 60 to make the pins lie on the same horizontal plane.

[0045] The flux component 53 includes a flux bracket 531 and a flux holding tank 532. The flux bracket 531 is vertically fixed below the solder dipping transfer mechanism 51 and is located behind the pin flattening assembly 52. The flux holding tank 532 is fixedly connected to the top of the flux bracket 531 along the X-axis direction and is used to hold the flux. The solder dipping transfer mechanism 51 moves the solenoid valve skeleton 60 above the flux component 53 so that the PIN pins of the solenoid valve skeleton 60 can be evenly coated with the flux.

[0046] The solder dipping mechanism 54 includes a solder dipping lifting module 541, a solder pot 542 and a solder cup 543. The solder dipping lifting module 541 is installed below the solder dipping transfer mechanism 51 and is located behind the flux component 53. The solder pot 542 is installed on the solder dipping lifting module 541, and the solder cup 543 is installed in the solder pot 542. During operation, the solder dipping transfer mechanism 51 moves the solenoid valve skeleton 60 above the solder dipping mechanism 54 so that the PIN pins of the solenoid valve skeleton 60 are immersed in the molten solder in the solder cup 543, covering its surface with a layer of solder to strengthen the electrical connection between the pins and the wires. Since the PIN pins need to be soldered into the characteristic convex plane of the solenoid valve skeleton 60, and the translational dip soldering will cause the solder liquid level to contact the solenoid valve skeleton 60, easily scalding the solenoid valve skeleton 60. Therefore, the rotation module 513 drives the solenoid valve skeleton 60 to perform a rotational movement in the X-Y plane for inclined dip soldering, which can not only avoid the solder liquid level contacting the solenoid valve skeleton 60 but also enable the PIN pins to be fully soldered.

[0047] Reference Figures 8 - 10, the blanking device 10 includes a second Y-axis linear motion module 101, a second X-axis linear motion module 102, a jaw blanking module 103, and a third Y-axis linear motion module 104; the second Y-axis linear motion module 101 is installed below the soldering transfer mechanism 51 and behind the soldering mechanism 54, and a horizontal blanking fixture 1011 for accommodating the solenoid valve skeleton 60 is installed on the slider of the second Y-axis linear motion module 101; the second X-axis linear motion module 102 is installed behind the second Y-axis linear motion module 101, and a rotary module 1021 is installed on the slider of the second X-axis linear motion module 102.

During operation, the rotary die first drives the vertical blanking fixture 1021a to rotate 90 degrees forward, and the second Y-axis linear motion module 101 transfers the solenoid valve skeleton 60 on the horizontal blanking fixture 1011 to the vertical blanking fixture 1021a. Then the rotary die drives the vertical blanking fixture 1021a to rotate 90 degrees backward, thereby converting the solenoid valve skeleton 60 into a vertical state.

[0048] The lead trimming assembly 6 and the testing and inspection assembly 7 are arranged at intervals beside the second X-axis linear motion module 102; the lead trimming assembly 6 includes a plurality of pneumatic scissors 61, which are arranged at intervals and installed beside the second X-axis linear motion module 102; the testing and inspection assembly 7 includes a plurality of test probes 71, a translation cylinder 72 for driving the test probes 71 to move, and a CCD detector. The test probes 71 are used to perform resistance testing and withstand voltage testing on the blanked solenoid valves. The CCD detector is not shown in the figure and is used to detect and identify the pins, soldering, and winding conditions of the solenoid valves to determine whether the solenoid valves are qualified. The qualified solenoid valves are transported to the picking position of the tray machine 8 through the jaw blanking module 103 and the third Y-axis linear motion module 104.

[0049] Reference Figure 11, the tray arranging machine 8 includes a tray transfer module 81, a tray separating mechanism 82, a tray arranging jaw module 83 and a tray stacking mechanism 84. The tray transfer module 81 is installed beside the discharging end of the discharging device 10 along the Y-axis direction. There are a tray separating station, a tray arranging station and a tray stacking station on the tray transfer module 81. The tray separating station is used for stacking multiple empty trays. The tray arranging jaw module 83 is installed above the tray arranging station along the X-axis direction. During use, the tray at the bottom of the tray separating mechanism 82 itself is separated, and driven by the tray transfer module 81, it moves along the Y-axis direction from the tray separating station to the tray arranging station; when the tray is placed at the tray arranging station, the tray arranging jaw module 83 grabs the solenoid valve products on the discharging device 10 and places them in the tray. After the tray is filled with products, the tray transfer module 81 moves the tray along the Y-axis direction to the tray stacking station again. At the same time, under the action of the tray stacking mechanism 84, the tray is stacked at the bottom of the tray stacking mechanism 84, and thus a tray arranging operation is completed. The above tray separating, tray arranging and tray stacking actions are cycled until there is no tray at the tray separating station or the tray stacking station is full of trays. Then, the same number of empty trays are put into the tray separating station of the tray arranging machine 8 to achieve continuous operation and improve work efficiency.

[0050] The working process of this solenoid valve automatic production line is as follows:

[0051] ① Automatic pin insertion: The first feeding device 1 automatically conveys the solenoid valve skeleton 60 and guides the solenoid valve skeleton 60 into the pin insertion station of the pin insertion machine 2;

[0052] ② Automatically transfer to the automatic winding machine 4: The solenoid valve skeleton 60 with pins inserted on the pin insertion machine 2 automatically flows into the second vibrating plate 31 of the second feeding device 3 for conveying. The transfer and loading mechanism 33 grabs the solenoid valve skeleton 60 and places it on the first transfer fixture 40 of the front-section transfer mechanism 91 of the transfer vehicle device 9, and then is transferred to the winding machine 4 through the front-section transfer mechanism 91;

[0053] ③ Automatic winding: The winding machine 4 automatically winds the solenoid valve skeleton 60;
