Description

Technical Field

[0001] The utility model relates to the technical field of valve core production, and more specifically, to a valve core feeding device. Background Art

[0002] Plastic ball valves have the advantages of simple structure, flexible operation, good sealing performance, etc., and are widely used in many industries. Plastic ball valves are generally produced by injection molding. After the valve core is produced, the valve body is produced by secondary injection molding outside the valve core, and then the handle is assembled to complete the production. The existing valve core is generally processed manually. During the process, the valve core is simply loaded through a material frame or a conveyor belt. Some processes of the valve core can be processed by automated equipment. For example, in the secondary injection molding process of the valve core, the valve core can be mechanically grasped and placed in the mold. The manipulator can produce 24 hours a day, which can improve production efficiency. However, the manipulator needs to grasp the neatly placed valve core from a fixed point. It is difficult to do the valve core placement and loading work 24 hours a day manually. The manual loading work method is also relatively labor-intensive, so it is not suitable for the manual placement of the valve core. In the existing equipment, there is a lack of automatic placement and loading device for the valve core. Utility Model Content

[0003] The utility model is to overcome the defect of the prior art that there is no automatic placement and loading device for the valve core, and provide a valve core loading device to realize the automatic placement and loading of the valve core.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a loading device for a valve core, comprising: a frame, a feeding assembly connected to the frame, a loading assembly and a placement piece; the feeding assembly comprises a feeder connected to the frame, a feeding trough installed on the feeder and used to place the valve core, a telescopic piece installed on the feeding trough, a first receiving piece and a second receiving piece respectively connected to the frame for sliding and used to receive the valve core, a first driving unit connected to the frame and used to drive the first receiving piece and the second receiving piece to move away from the valve core, a first limit plate and a second limit plate respectively installed on the first receiving piece and the second receiving piece, and a first clamping piece connected to the frame; when the telescopic piece is extended, the valve core at the end of the feeding trough is blocked, the first limit plate and the second limit plate are enclosed to form a cavity for accommodating the valve core, the loading assembly is used to clamp the valve core located in the cavity and transfer it to the placement piece for loading, and the placement piece is provided with a plurality of placement positions for placing the valve core.

[0005] The feeder adopts a straight vibrator, and the side walls of the feed trough are used to limit the rotation of the valve core, thereby moving the valve core to the first receiving member and the second receiving member. The first limiting plate and the second limiting plate are respectively arranged on the first receiving member and the second receiving member. The first limiting plate and the second limiting plate together form a cavity for accommodating the valve core, which prevents the valve core from falling and rotating. After the valve core is sent out from the feed trough and enters the cavity, the telescopic member extends out to block the valve core at the end of the feed trough, and the end of the feed trough refers to the end close to the cavity; then the first clamping member temporarily clamps the valve core in the cavity, and then the first driving unit drives the first receiving member, the second receiving member, the first limiting plate and the second limiting plate away from the valve core, and the loading assembly moves down to clamp the valve core on the first clamping member, and moves the valve core to the placement member for loading. The placement piece is provided with multiple placement positions for placing multiple valve cores at the same time, so that two or three valve cores can be moved into the cavity at the same time, and the loading component clamps two or three valve cores at a time for loading; the placement piece can also be provided with multiple placement positions in the moving direction of the loading component, and the loading component clamps the valve cores in turn and places them on the placement positions; the freedom of movement of the loading component can also be further increased, and multiple rows of placement positions can be provided on the placement piece at the same time, so that the loading component clamps the valve cores in turn and places them in each row of placement positions to complete the loading work; subsequently, the robot arm arranged at the rear will take the valve core away from the placement piece for injection molding or other processes.

[0006] The front end of the feeding trough can be fed through a vibrating plate. The first receiving member and the second receiving member can move in two directions. One is to move along the feeding direction of the feeding trough, away from the feeding trough and then away from the valve core; the other is to move along the two sides of the feeding trough, the first receiving member and the second receiving member move away from each other, and then away from the valve core, to make room for the clamping of the loading assembly. Further, the working surfaces for placing the valve core on the feeding trough, the first receiving member and the second receiving member are all concave arc surfaces. Further, the placement position is a through hole or groove that can limit the rotation of the valve core. When the feeding trough of the device moves the valve core, the valve handle of the valve core faces downward, so the placement position is set to a through hole that is consistent with the side shape of the valve handle and slightly larger in size. The placement position can be set to a through hole or groove with elasticity, so that the valve core cannot rotate after being placed in the placement position. Further, the first clamping member is a clamping claw cylinder, and its clamping claw is provided with a groove corresponding to the valve handle shape of the valve core, which can stably clamp the valve core.

[0007] Preferably, the loading assembly includes a first mobile frame connected to the frame for transverse sliding, a second driving unit connected to the frame and used to drive the first mobile frame to move, a second mobile frame installed on the first mobile frame for longitudinal sliding, a third driving unit connected to the first mobile frame and used to drive the second mobile frame to move, and a clamping assembly installed on the second mobile frame, wherein the clamping assembly is used to clamp the valve core.

[0008] In the feeding assembly, the clamping assembly is located above the cavity, and the third driving unit drives the clamping assembly to descend to clamp the valve core located in the cavity, and then rises and resets, and then the second driving unit drives the first movable frame to move horizontally, and moves the clamping assembly and the valve core together to above the placement piece, and the third driving unit then drives the clamping assembly to descend and place the valve core on the placement position of the placement piece.

[0009] Preferably, the clamping assembly includes a turntable rotatably connected to the second movable frame, a fourth driving unit connected to the first movable frame and used to drive the turntable to rotate, and a plurality of second clamping members installed at the lower part of the turntable, wherein the second clamping members are used to clamp the valve core.

[0010] In the clamping assembly, multiple second clamping members are installed on the circumference of the bottom of the turntable. After the first second clamping member clamps the valve core and rises, the fourth drive unit drives the turntable to rotate, so that the next second clamping member rotates to the top of the cavity, and then descends to clamp the valve core. After multiple second clamping members clamp the valve core in turn, the second drive unit drives the first mobile frame to move horizontally, so that multiple valve cores can be moved at a time, and then the placement position on the placement member is set to correspond to each second clamping member, so that multiple valve cores can be placed at a time to improve efficiency. Further, the fourth drive unit is a servo motor and is connected to a hollow rotating table. The hollow rotating table is installed on the second mobile frame and the rotating end is connected to the turntable; further, a servo motor origin sensor is installed on the frame, and a sensor induction sheet is installed on the rotating end of the hollow rotating table.

[0011] Preferably, the clamping assembly also includes a pneumatic slip ring installed on the second movable frame and a plurality of solenoid valves installed on the lower part of the turntable, the pneumatic slip ring is connected to the solenoid valve, the second clamping member is a clamping claw cylinder and is connected to the solenoid valve, and the number of the solenoid valves is consistent with the number of the second clamping members.

[0012] The gas-electric slip ring is also called the gas-electric rotary joint. It is a combination of an electric slip ring and a gas slip ring. It can rotate 360 ​​degrees to conduct electricity and transmit various gas media in combination. The principles of the gas-electric slip ring and the electric slip ring are similar. The electric slip ring is used to rotate 360 ​​degrees to conduct electricity or transmit various signals; the gas slip ring is used to rotate 360 ​​degrees and circulate gas. The gas can be carbon monoxide, compressed air, water vapor and other gases. In this solution, the second clamping member selects a clamping cylinder, the fixed end of the gas-electric slip ring is installed on the second mobile frame, and a turntable is installed on the rotating end. The wires and air pipes led out from the rotating end are connected to the solenoid valve to provide current and airflow for the solenoid valve. The solenoid valve is then connected to the second clamping member through the air pipe. The number of solenoid valves is consistent with the number of second clamping members.

[0013] Preferably, the clamping assembly also includes an adapter installed at the bottom of the turntable, and the adapter is provided with an air inlet hole for connecting to the gas-electric slip ring, a plurality of air supply holes and an air discharge hole for connecting to the solenoid valve, and the air inlet hole is connected to all the air supply holes.

[0014] The rotating end of the existing gas-electric slip ring generally only leads to one air pipe. Multiple solenoid valves and a second clamping member are installed on the turntable of the device. The air pipe needs to be diverted. The air inlet of the adapter is used to connect with the air pipe. At the same time, the air inlet is connected to multiple air delivery holes, which are respectively connected to the solenoid valves. At the same time, the adapter is fixedly connected to the turntable to avoid the air pipe being too messy. The air leakage hole on the connecting member is used for the air leakage of the solenoid valve. Furthermore, the solenoid valve adopts a two-position three-way solenoid valve, whose input port P is connected to the air delivery hole, the discharge ports R and S are respectively connected to the air leakage hole, and the output ports A and B are respectively connected to the second clamping member.

[0017] Preferably, the adapter is provided with sealing rings on both sides of the notch.

[0018] A sealing ring is provided to increase the air tightness between the slot and the turntable to further prevent air leakage.

[0019] Preferably, a third limit plate is installed on the first clamping member, and an air blowing device for aligning the valve core is installed on the feeding trough, and an air outlet of the air blowing device faces the third limit plate.

[0020] When the valve core is placed on the feeding trough, its valve handle faces downward. When the valve core moves into the cavity, the third limit plate limits the valve handle, and at the same time, the air blowing device blows air to the valve handle to make the valve handle fit with the third limit plate, thereby keeping the valve core vertical. Then the first clamping member clamps the valve handle again, and the loading device loads the material to avoid the valve core from tilting during loading. Specifically, the third limit plate is arranged on one of the clamping claws of the first clamping member.

[0021] Preferably, the feeding assembly further comprises a lifting member mounted on the frame, and the first clamping member is mounted on the lifting member.

[0022] When the loading assembly clamps multiple valve cores in sequence, it needs to descend multiple times for clamping, which may cause the clamped valve cores to fall during the multiple descents. A lifting member is provided to deliver the valve cores to the loading assembly, thereby eliminating the need for the loading assembly to descend multiple times in the process of clamping the valve cores, thereby preventing the clamped valve cores in the loading assembly from shaking or falling off during the multiple descents, and making the loading work more stable.

[0023] Preferably, a distance sensor for detecting the movement of the valve core is installed on the first receiving member.

[0024] A distance sensor is provided to detect the movement of the valve core into the cavity. After the distance sensor detects that the valve core has moved into place, the device starts the next step. Furthermore, a distance sensor is also installed on the second receiving member.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The front end of the feed trough is placed on the discharge port of the vibration plate. The valve core can enter the feed trough in turn under the action of the vibration plate, and then move into the cavity under the action of the feeder. During the process, the feed trough and the first limit plate always limit the rotation of the valve core to achieve neat feeding of the valve core. Then the first clamping member clamps the valve core, and the first driving unit drives the first receiving member and the second receiving member away from the valve core. The loading assembly then clamps the valve core and moves it to the placement position of the placement member, thereby realizing automatic loading of the valve core and allowing the valve core to be neatly stacked on the placement member to facilitate material picking by the robot.

The loading component 3 is used to clamp the valve core in the cavity 210 and transfer it to the placement member 4 for loading. The placement member 4 is provided with a plurality of placement positions 401 for placing the valve core.

[0044] The feeder 201 adopts a straight vibrator, and the side walls of the feed trough 202 are used to limit the rotation of the valve core, thereby moving the valve core to the first receiving member 204 and the second receiving member 205. The first receiving member 204 and the second receiving member 205 are respectively provided with a first limiting plate 207 and a second limiting plate 208. The first limiting plate 207 and the second limiting plate 208 are surrounded by a cavity 210 for accommodating the valve core.

In the clamping assembly 305, a plurality of second clamping members 308 are installed on the bottom circumference of the turntable 306. After the first second clamping member 308 clamps the valve core and rises, the fourth driving unit 307 drives the turntable 306 to rotate, so that the next second clamping member 308 rotates to the top of the cavity 210, and then descends to clamp the valve core.

[0057] like Figure 4 As shown, a third limiting plate 6 is installed on the first clamping member 209. Figure 2 As shown, an air blowing device 7 for aligning the valve core is installed on the feeding trough 202, and the air outlet of the air blowing device 7 faces the third limit plate 6. The feeding assembly 2 also includes a lifting member 8 installed on the frame 1, and the first clamping member 209 is installed on the lifting member 8. A distance sensor 9 for detecting the movement of the valve core is installed on the first receiving member 204.

[0058] When the valve core is placed on the feeding trough 202, its valve handle faces downward. When the valve core moves into the cavity 210, the third limit plate 6 limits the valve handle, and the air blowing device 7 blows the valve handle to make the valve handle fit with the third limit plate 6, thereby keeping the valve core vertical. Then the first clamping member 209 clamps the valve handle again, and the loading device loads the material again to avoid the valve core from being skewed during loading. Specifically, the third limit plate 6 is set on one of the clamping claws of the first clamping member 209. When the loading assembly 3 sequentially clamps multiple valve cores, it needs to be lowered for clamping multiple times, which may cause the clamped valve core to fall during the multiple lowering processes. The lifting member 8 is provided to deliver the valve core to the loading assembly 3, eliminating the multiple lowering actions of the loading assembly 3 in the process of clamping the valve core, avoiding the clamped valve core in the loading assembly 3 from shaking or falling off during the multiple lowering processes, and making the loading work more stable. The distance sensor 9 is provided to detect the movement of the valve core into the cavity 210 . After the distance sensor 9 detects that the valve core has moved into position, the device starts the next step. Furthermore, the distance sensor 9 is also installed on the second receiving member 205 .

[0059] In this embodiment, the air blowing device 7 is a metal air pipe fixedly mounted on the feeding trough 202 and connected to the high-pressure air flow. The lifting member 8 is a telescopic cylinder.

[0060] The rest of the working principle and working process of this embodiment are consistent with those of Embodiment 1 or Embodiment 2.
