[0002] Solenoid valves are industrial equipment controlled by electromagnetics. They are basic automation components used to control fluids. They are actuators and are widely used in automated production. Figure 1 As shown, the solenoid valve includes an air circuit block 1a, in which a manual adjustment rod 1b is vertically inserted, and a spring 1c is connected to the outer surface of the manual adjustment rod 1b. The spring 1c will push the manual adjustment rod to move toward the side away from the air circuit block 1a. Therefore, a socket 11c is also horizontally arranged on the air circuit block, and a pin needle 1d needs to be inserted into the socket 11c. The pin needle 1d can be engaged with the manual adjustment rod 1b to limit the position of the manual adjustment rod. The plug-in assembly of the pin needle and the air circuit block is usually performed by manual assembly, which has a low degree of automation and low work efficiency. Even some automated production equipment has certain deficiencies in the alignment of the pin needle and the socket of the air circuit block and the compression of the manual adjustment rod and the air circuit block, which brings inconvenience to the quick plug-in of the pin needle and affects efficiency.

[0045] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0046] The pin needle 1d plugging mechanism of the solenoid valve 100 of the present invention is used to plug the pin needle 1d into the plug hole 11c of the gas circuit block 1a. During the plugging, the manual adjustment rod 1b has been vertically plugged into the gas circuit block 1a.

[0047] See attached Figure 2 As shown, the pin needle 1d plug-in mechanism comprises a placement seat 1, a handling device 2, a pin needle feeding device 3 and a plug-in device 4. The placement seat 1 is used to place the gas circuit block 1a, and the placement seat 1 has a placement groove for partially inserting the gas circuit block 1a from its upper end surface downward. Figure 1 As shown, the gas circuit block 1a includes a base 11a and a plug-in portion 11b arranged up and down, the plug-in portion 11c is arranged on the plug-in portion 11b, and the base 11a is embedded in the placement groove. The transport device 2 is used to transport the gas circuit block 1a, that is, to transport the processed gas circuit block 1a to the placement groove, and then transport the gas circuit block 1a plugged with the pin needle 1d to the next station. The transport device 2 includes at least one clamping component 21, and the clamping component 21 is used to clamp the gas circuit block 1a, and the clamping component 21 can always press the manual adjustment rod 1b into the gas circuit block 1a during the pin needle 1d plugging process.

[0048] In this embodiment, because the spring 1c outside the manual adjustment rod 1b will push the manual adjustment rod 1b upward, the clamping assembly 21 can clamp the gas circuit block 1a while pressing the manual adjustment rod 1b down, so that the manual adjustment rod 1b is always pressed tightly inside the gas circuit block 1a to meet processing requirements.

[0049] See attached Figure 3 As shown, the pin needle feeding device 3 is arranged on one side of the second direction (X direction) of the placement seat 1, and the pin needle feeding device 3 is used to transport the pin needles 1d to the plug-in station one by one, and at this time, the pin needles 1d are coaxial with the socket 11c. The plug-in device 4 includes a plug-in assembly 41 located on one side of the first direction (Y direction) of the placement seat 1, and the plug-in assembly 41 includes an ejector pin 411 that can move linearly along the first direction, and the ejector pin 411 extends along the first direction. The ejector pin 411 can be plugged during the movement to push the pin needle 1d on the plug-in station into the socket 11c. When the pin needle 1d arrives at the plug-in station, the pin needle 1d is coaxially aligned with the socket 11c, and at this time, the ejector pin 411 moves, pushing the pin needle 1d to move along the first direction (that is, the axial direction of the pin needle 1d and the ejector pin 411), and inserting it into the socket 11c, completing the plug-in of the pin needle 1d of the solenoid valve 100.

[0050] In this embodiment, the automatic plugging of the pin 1d is realized by the cooperation of the pin feeding device 3 and the plugging device 4. The pin 1d feeding mechanism is used to align the pin 1d with the plug hole 11c, and the ejector pin 411 pushes the pin 1d to move, thereby realizing the precise plugging of the pin 1d.

[0051] In one embodiment, see the attached Figure 4 As shown, the ejector pin 411 moves under the driving of the first driving member 412. The first driving member 412 may be a cylinder, one of which is fixed to the ejector pin 411 through a connecting member, so as to drive the ejector pin 411 to move back and forth.

[0052] In one embodiment, the ejector pin 411 is a mold pin, which has a relatively high hardness and will not be deformed when pushing the pin pin 1d.

[0053] The ejector pin 411 is relatively long, so in one embodiment, the plug-in assembly 41 further includes a guide block 413, which is located between the first driving member 412 and the placement seat 1. The ejector pin 411 is inserted into the guide block 413, which is a movement guide for the ejector pin 411, thereby reducing the displacement of the ejector pin 411 during movement. When the ejector pin 411 abuts against the pin needle 1d, the ejector pin 411 is coaxial with the pin needle 1d, that is, when the gas circuit block 1a is placed in the placement slot, the jack 11c is coaxial with the pin needle 1d.

[0054] In one embodiment, see the attached Figure 4 As shown, the plug-in device 4 further includes a limit assembly 42, which is located at the other side of the first direction of the placement seat 1. The limit assembly 42 includes a limit block 421 that can move linearly along the first direction, and the limit block 421 can abut against the gas circuit block 1a and block the opening of the plug hole 11c away from the ejector pin 411.

[0055] In this embodiment, a limit block 421 is added. When the pin 1d is plugged in, the limit block 421 needs to abut against the opening of the socket 11c to limit the position of the pin inserted into the socket 11c and prevent the pin from moving too far when inserted into the socket 11c.

[0056] See attached Figure 4 As shown, the limiting assembly 42 further includes a second driving member 422 , the limiting block 421 and the second driving member 422 are fixedly connected, and the second driving member 422 drives the limiting block 421 to move.

[0057] In one embodiment, see the attached Figure 7As shown, the transport device 2 also includes a transverse movement component 22, a lifting component 23 and a rotating component 24. The lifting component 23 is fixedly connected to the transverse movement component 22 and can reciprocate along the second direction driven by the transverse movement component 22. The rotating component 24 is corresponding to the clamping component 21 and drives the corresponding clamping component 21 to rotate along a vertical axis. Each of the rotating components 24 is connected to the lifting component 23.

[0058] In this embodiment, the traverse assembly 22 drives the clamping assembly 21 to move to the position of the previous station, and clamps the gas circuit block 1a with the hand-adjustable rod 1b placed thereon. After the clamping assembly 21 clamps the gas circuit block 1a, the traverse assembly 22 drives the clamping assembly 21 to move to the top of the placement slot. After the clamping assembly 21 rotates 90 degrees under the drive of the rotating assembly 24, the lifting assembly 23 drives the clamping assembly 21 to descend, and the gas circuit block 1a is placed in the placement slot. After the gas circuit block 1a is plugged with the pin 1d, the clamping assembly 21 can be driven by the traverse assembly 22 to move to the next station.

[0059] In this embodiment, the structure of the transport device 2 can move the gas circuit block 1a in the space to realize the transport of the gas circuit block 1a.

[0060] In one embodiment, two clamping assemblies 21 are provided, and the two clamping assemblies 21 are spaced apart in the second direction. At this time, when one clamping assembly 21 carries the gas circuit block 1a on the previous station, the other clamping assembly 21 can carry the processed gas circuit block 1a to the next station. Providing two clamping assemblies 21 can improve the carrying efficiency of the carrying device 2.

[0061] In one embodiment, the lateral movement assembly 22 includes a stand, on which a lateral movement module is fixed, and the output end of the lateral movement module is fixedly connected to the lifting assembly 23, and the lateral movement module is a linear module, which drives the lifting assembly 23 to reciprocate along the second direction. The lifting assembly 23 is a lifting cylinder, the housing of which is fixed to the lateral movement module, and the piston rod of the lifting cylinder is vertically arranged and fixedly connected to the rotating assembly 24. The rotating assembly 24 is a rotating cylinder.

[0062] In this embodiment, after the previous station clamps the gas circuit block 1a, the gas circuit block 1a needs to be rotated 90 degrees to change the gas circuit block 1a to a position where the plug hole 11c extends along the first direction, and the pin 1d can be plugged in at this time, so a rotating component 24 is provided to rotate the clamped gas circuit block 1a. Of course, if the previous station can realize that the plug hole 11c extends along the first direction when the clamping component 21 clamps the gas circuit block 1a, the handling device 2 does not need the rotating component 24 at this time.

[0063] See attached Figure 7As shown, the clamping assembly 21 includes a clamping cylinder 211, and a clamping block 212 is fixed on the clamping jaws of the clamping cylinder 211, and the gas circuit block 1a can be clamped between the clamping blocks 212. The clamping block 212 clamps the plug-in portion 11b of the gas circuit block 1a, so that when the clamping assembly 21 places the base 11a of the gas circuit block 1a into the placement groove, no interference will be caused.

[0064] A pressing block 213 fixedly connected to the clamping cylinder 211 is also provided between the two clamping blocks 212. The pressing block 213 can abut against the upper end surface of the manual adjustment rod 1b to press the manual adjustment rod 1b into the gas circuit block 1a. The pressing block 213 is fixedly connected to the housing of the clamping cylinder 211 and extends downward. The clamping assembly 21 first moves downward until the pressing block 213 presses against the manual adjustment rod 1b. At this time, the manual adjustment rod 1b is located and will not move upward and is confined in the gas circuit block 1a. Then the two clamping blocks 212 approach each other to clamp the gas circuit block 1a.

[0065] During the plugging process of the pin 1d, the pressing block 213 is always pressed tightly on the manual adjustment rod 1b and its position remains unchanged, so as to prevent the position of the manual adjustment rod 1b from changing when the pin 1d is assembled.

[0066] In one embodiment, see the attached Figure 5 and attached Figure 6 As shown, the pin needle feeding device 3 includes a cutting assembly 31 and a vibration plate. The cutting assembly 31 includes a cutting plate 311 that can reciprocate along the second direction. The cutting plate 311 includes a placement hole 3111 that is only used to insert a pin 1d. The placement hole 3111 reciprocates between the feeding station and the insertion station during the movement of the cutting plate 311. The movement direction of the cutting plate 311 is Figure 6 The vibrating plate 32 is used to vibrate the pin needles 1d one by one into the placement holes 3111 of the loading station.

[0067] In this embodiment, the vibration plate transmits the pin needle 1d through its own transmission channel 321. When the cutting plate 311 moves to the coaxial position between the placement hole 3111 and the transmission channel 321, the cutting plate 311 reaches the loading station. At this time, the vibration plate can vibrate a pin needle 1d into the placement hole 3111 during the vibration process. Then the cutting plate 311 moves to the plug-in station. At this time, the placement hole 3111 and the plug-in hole 11c are coaxial, and the pin needle 1d can be plugged. See the attached Figure 6 As shown, the axis of the placement hole 3111 extends along the first direction, and the pin needle 1d also extends along the first direction in the placement hole 3111.

[0068] See attached Figure 5As shown, in one embodiment, the cutting plate 311 is connected to the third driving member 313, and the third driving member 313 is used to drive the cutting plate 311 to reciprocate along the second direction.

[0069] In one embodiment, the cutting device further comprises a guide plate 312, and the guide plate 312 is provided with a slide groove for the cutting plate 311 to slide. The setting of the guide plate 312 plays a guiding role in the movement of the cutting plate 311, and avoids the deviation of the cutting plate 311 during the movement. The guide plate 312 is provided with a clearance groove for the pin needle 1d to pass through at the loading station and the plug-in station, and the clearance groove and the slide groove are connected. That is, although the guide plate 312 can play a guiding role, it cannot hinder or block the pin needle 1d from entering and sliding out of the placement hole 3111.

[0070] In one embodiment, a sensor is further provided at the loading station, and the sensor is used to detect whether a pin 1d is plugged into the placement hole 3111 at the loading station. Only when the sensor detects that there is a pin 1d in the placement hole 3111, the third driving member 313 drives the cutting plate 311 to move, so that the cutting plate 311 moves to the plugging station, thereby ensuring that there is a plugged pin 1d in the placement hole 3111 of the plugging station.

[0071] In one embodiment, the sensor is fixed on the guide plate 312, and the sensor is a through-beam sensor, including a transmitting section and a receiving end spaced apart from each other. A detection hole is provided on the cutting plate 311, and the detection hole is connected to the placement hole 3111. The two are in a cross shape. When the placement hole 3111 is moved to the loading station, the through-beam light between the transmitting end and the receiving end can pass through the detection hole and the placement hole 3111. When the through-beam light is blocked, it indicates that there is a pin 1d in the placement hole 3111.

[0072] In one embodiment, see the attached Figure 4 As shown, the placement seat 1 is also provided with a clamping assembly 11 on the side away from the pin needle loading device 3 in the second direction. The clamping assembly 11 includes a clamping block 111 that can reciprocate along the second direction. The clamping block 111 can abut against the side wall of the gas circuit block 1a to press the gas circuit block 1a against the side wall of the placement groove.

[0073] The clamping block 111 abuts against the base 11 a. The position of the gas circuit block 1 a is limited in the horizontal direction by the arrangement of the clamping assembly 11 , so as to prevent the gas circuit block 1 a from being offset during the processing.

[0074] The pressing assembly 11 further includes a fourth driving member 112 , which is fixedly connected to the pressing block 111 and is used to drive the pressing block 111 to reciprocate along a straight line.

[0075] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
