Description

Technical Field

[0001] This invention relates to the assembly of nozzle assemblies, and more specifically to a turret-type assembly device and method for nozzle assemblies. Background Technology

[0002] Figure 1 As a component of a nozzle in the prior art, it is composed of Figure 2 The main body plug 1 and Figure 3 The air tank 2 is assembled by filling the middle part with nitrogen. Compared with the traditional method of using a spring to drive the wrench, this device uses a full-filled air tank as an elastic recovery component. Currently, the assembly of this nozzle assembly is done manually, that is, by manually inserting the air tank 2 upward into the main body plug 1, which is inefficient and laborious.

[0003] The present invention aims to provide a novel automated production line for assembling the main body plug 1 and the air bag 2. Summary of the Invention

[0004] This invention provides a turret-type assembly device for a nozzle assembly, wherein the nozzle assembly consists of an air tank and a main body plug, and the turret-type assembly device is provided with a turret body, and the turret body is equipped with a main body plug clamping and pressing mechanism and an air tank clamping and pushing mechanism installed on its upper and lower parts.

[0005] The main body plug clamping and pressing mechanism is provided with an electromagnetic control mechanism, a pressing mechanism and a first clamping mechanism in sequence from top to bottom. The gas bag clamping and pushing mechanism is provided with an upper lifting mechanism and a second clamping mechanism in sequence from bottom to top. The first clamping mechanism and the pressing mechanism each include a plurality of first jaws and a plurality of pressing push rods circumferentially arranged on the turret body. The second clamping mechanism and the upper lifting mechanism each include a plurality of second jaws and a plurality of upper lifting push rods circumferentially arranged on the turret body. The electromagnetic control mechanism includes a sector magnet and a plurality of solenoid valves circumferentially arranged on the turret body. The solenoid valves, first jaws, pressing push rods, second jaws and upper lifting push rods correspond one-to-one in the axial direction. The solenoid valves, the first clamping mechanism, the pressing mechanism, the second clamping mechanism and the upper lifting mechanism rotate synchronously with the turret body. The sector magnet is stationary on the turret body.

[0006] When the solenoid valve rotates to the starting position of the sector magnet, the solenoid valve senses the magnetic field and closes the first jaw connected to it to hold and fix the main body plug. When the solenoid valve leaves the area of ​​the sector magnet, the first jaw connected to it opens.

[0007] When the solenoid valve rotates to the latter half of the fan-shaped magnet's rotation, the downward push rod floats downward and presses against the upper end face of the main body plug held by the first gripper, while the upward push rod floats upward and pushes the air bag held by the second gripper upward. The air bag is then inserted into the main body plug to form the nozzle assembly.

[0008] Furthermore, the turret body is provided with a fifth turntable, a second turntable, a first turntable, a third turntable, and a fourth turntable from top to bottom, which are used to install a solenoid valve, a pressing mechanism, a first gripper, a second gripper, and an lifting mechanism, respectively.

[0009] Furthermore, the first turntable is provided with a plurality of first opening slots along the circumference, and the first grippers are respectively installed below each of the first opening slots;

[0010] The main plug is secured in the first opening groove by a convex ring and its bottom is held by the first gripper.

[0011] Furthermore, an upper cam ring and a lower cam ring are statically mounted on the turret body;

[0012] The upper cam ring is located above the first clamping mechanism. The outer side wall of the upper cam ring is provided with cam grooves of varying heights along the circumference. The top of the pressing mechanism cooperates with the cam grooves to float up and down.

[0013] The lower cam ring is located below the second clamping mechanism. The upper end face of the lower cam ring has cam surfaces of varying heights along its circumference. The bottom of the upper lifting mechanism cooperates with the cam surfaces to float up and down.

[0014] The downward protruding area of ​​the cam groove and the upward protruding area of ​​the cam surface are both located within the axial projection area of ​​the latter half of the sector magnet.

[0015] Furthermore, the downward push rod is provided with a first guide rail bracket, a first push rod, and a first spring. The first guide rail bracket is axially fixed on the turret body. The first push rod is slidably mounted on the first guide rail bracket. The upper end of the first push rod is provided with a first roller that rolls with the cam groove. The lower end face of the first push rod is plugged with the downward push body. The bottom end of the first spring is connected to the first push rod, and the top end of the first spring is connected to the second turntable. The first spring provides an upward pulling force to the first push rod so that the first roller always rolls along the upper surface inside the cam groove.

[0016] Furthermore, the upper push rod is equipped with a linear bearing, which is connected to the fourth turntable via an upper mounting plate. A lower fixed plate is provided at the bottom of the linear bearing, and a roller seat is installed at the bottom of the lower fixed plate. The roller seat is equipped with a second roller that rolls with the cam surface. The bottom end of the piston rod of the linear bearing is fixedly connected to the lower fixed plate, and the upper end of the piston rod slides through the upper mounting plate and is fixedly connected to the upper top plate. A second spring is sleeved on the piston rod between the upper mounting plate and the lower fixed plate. The second spring provides downward pressure to the roller seat, so that the second roller always rolls along the upper surface of the cam surface.

[0017] Furthermore, the turret body is equipped with a main body plug feeding device, which feeds the main body plug into the first opening slot of the first turntable located in front of the sector magnet in the rotation direction;

[0018] A transfer mechanism is provided on the rear side of the sector magnet in the rotation direction, and the nozzle assembly is transferred away by the transfer mechanism.

[0019] A method for assembling and transferring a turret-type assembly device based on the above-mentioned nozzle assembly, the method comprising three steps: loading, assembly, and transfer, the specific steps being as follows:

[0020] Feeding: The main body plug is fed into the first open slot located in front of the sector magnet in the rotation direction by the main body plug feeding device. The solenoid valve rotates into the sector magnet area, senses the magnetic field, and closes the first gripper connected to it to clamp the main body plug.

[0021] The air bag is conveyed to the second gripper opening at the beginning of the sector magnet by the air bag feeding device, and then the second gripper is closed to hold the air bag.

[0022] Assembly: When the solenoid valve rotates to the second half of the fan-shaped magnet's rotation, the downward push rod floats down and presses against the upper end face of the main body plug held by the first gripper, while the upward push rod floats up and pushes the air bag held by the second gripper upward, and the air bag is inserted into the main body plug to form the nozzle assembly.

[0023] Transfer: When the solenoid valve leaves the area of ​​the sector magnet, the first gripper connected to it is opened, and the second gripper corresponding to the first gripper is also opened at the same time, and the receiving device removes the nozzle assembly from the turret body.

[0024] The advantages of this invention are:

[0025] (1) A turret design is adopted, which simultaneously clamps the main body plug and the air bag during the rotation process, and the main body plug is pressed down and the air bag is pushed up and inserted into the main body plug;

[0026] (2) This is achieved through two cam rings: the lower pressing mechanism presses the main body plug downwards, and the upper pushing mechanism pushes the air bag upwards. The mechanically driven lower and upper pushing mechanisms have a low failure rate, simple structure, and are more efficient.

[0027] (3) By setting a stationary sector magnet to control the opening and closing of the first gripper that falls into the sector magnet area, the assembly line processing of three procedures is realized: releasing the first gripper to feed material, closing the first gripper to fix the main body plug, and releasing the first gripper to discharge material.

[0028] (4) The innovative turret-type assembly device for nozzle components provided by the present invention can fully realize the integrated production line operation of feeding, assembling and discharging of the main body plug and air bag. The whole process does not require manual intervention, which greatly improves processing efficiency and saves labor costs. Attached Figure Description

[0043] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0044] To fully understand this invention, detailed steps and structures will be presented in the following description to illustrate the technical solution of this invention. Preferred embodiments of the invention are described in detail below; however, in addition to these detailed descriptions, the invention may have other embodiments.

[0045] Reference Figure 3-4 As shown, the present invention provides a turret-type assembly device for a nozzle assembly, which includes a turret body 10. A main body plug clamping and pressing mechanism 100 and an air bag clamping and pushing mechanism 200 are mounted on the upper and lower parts of the turret body 10.

[0046] The main body plug clamping and pressing mechanism 100 is provided with an upper cam ring 140, a pressing mechanism 130 and a first clamping mechanism 120 in sequence from top to bottom. The air bag clamping and pushing mechanism 200 is provided with a lower cam ring 240, an upper lifting mechanism 230 and a second clamping mechanism 220 in sequence from bottom to top. The first clamping mechanism 120, the pressing mechanism 130, the second clamping mechanism 220 and the upper lifting mechanism 230 rotate synchronously with the turret body 10, and the upper cam ring 140 and the lower cam ring 240 are stationary on the turret body 10, that is, the upper cam ring 140 and the lower cam ring 240 do not rotate with the turret body 10.

[0047] The first clamping mechanism 120 and the pressing mechanism 130 each include a plurality of first grippers 121 and a plurality of pressing push rods 131 circumferentially disposed on the turret body 10. The first grippers 121 and the pressing push rods 131 correspond one-to-one in the axial direction of the turret body 10. As the turret body 10 rotates, the pressing push rods 131 cooperate with the upper cam ring 140 to float up and down. Figure 5 As shown.

[0048] The second clamping mechanism 220 and the upper lifting mechanism 230 each include a plurality of second clamping jaws 221 and a plurality of upper lifting push rods 231 circumferentially disposed on the turret body 10. The second clamping jaws 221 and the upper lifting push rods 231 correspond one-to-one in the axial direction of the turret body 10, and the second clamping jaws 221 correspond one-to-one with the first clamping jaws 121 in the axial direction of the turret body 10. During the rotation of the turret body 10, the upper lifting push rods 231 cooperate with the lower cam ring 240 to float up and down. Figure 5 As shown.

[0049] The working principle of this invention can be briefly described as follows: the main body plug 1 and the air bag 2 are respectively clamped by the first clamp 121 and the second clamp 221. During the rotation of the turret body 10, a portion of the downward push rod 131 cooperates with the upper cam ring 140, causing the downward push rod 131 to float downwards and press against the upper end face of the main body plug 1 held by the first clamp 121. Simultaneously, the upper push rod 231, which coincides axially with this portion of the downward push rod 131, cooperates with the lower cam ring 240 to float upwards, lifting the air bag 2 held by the second clamp 221 and inserting it into the slot of the main body plug 1. In this process, the upper end face of the main body plug 1 is pressed downwards, and the air bag 2 is lifted upwards, simultaneously applying force in both directions, thereby completing the assembly of the main body plug 1 and the air bag 2.

[0050] The turret body 10 is provided with a fifth turntable 113, a second turntable 112, a first turntable 111, a third turntable 211, and a fourth turntable 212 from top to bottom, which are used to install a solenoid valve 152, a pressing mechanism 130, a first gripper 121, a second gripper 221, and an lifting mechanism 230, respectively.

[0051] In an optional embodiment, the first turntable 111 is provided with a plurality of first opening slots along its circumference, the main body plug 1 is engaged in the first opening slots, and the first grippers 121 are respectively installed below each of the first opening slots. Figure 10 As shown, the main body clamping and pressing mechanism 100 is also provided with an electromagnetic control mechanism 150 for controlling the opening and closing of the first gripper 121. See further details. Figure 6 The electromagnetic control mechanism 150 includes a sector magnet 151 and several solenoid valves 152 circumferentially arranged on the turret body 10. The solenoid valves 152 are mounted on the fifth turntable 113, and the sector magnet 151 is stationary on the turret body 10, meaning it does not rotate with the turret body 10. The solenoid valves 152 and the first grippers 121 are corresponding and connected in the axial direction of the turret body 10. Each solenoid valve 152 controls the opening and closing of each first gripper 121. When a solenoid valve 152 rotates to the area of ​​the sector magnet 151, it senses the magnetic field and closes the corresponding first gripper 121. When a solenoid valve 152 leaves the area of ​​the sector magnet 151, it opens the first gripper 121. The sector magnet refers to the sector magnet 151 being sector-shaped along the rotation path of the turret body.

[0052] Before assembly, the main body plug 1 needs to be placed into the first opening slot by the main body plug feeding device. At this time, the first gripper 121 needs to be opened to facilitate the main body plug entering the first gripper 121. After the main body plug 1 and the air tank 2 are assembled, the first gripper 121 also needs to be opened to facilitate the discharge device to discharge the main body plug. Figure 1The workpiece is transferred away. This invention, by setting the orientation of the sector magnet 151, can precisely control the opening and closing orientation of the first gripper 121, thereby enabling the opening of the first gripper 121 to allow the main body plug 1 to enter, the closing of the first gripper 121 to clamp the main body plug 1, and the opening of the first gripper 121 to transfer the assembled nozzle assembly. It should be noted that after the first gripper leaves the area of ​​the sector magnet 151, the assembled nozzle assembly is removed first. At this time, the first gripper 121 is still in the open state. The main body plug feeding device then places the main body plug 1 into the first opening slot, enters the area of ​​the sector magnet 151, and is then clamped and fixed by the first gripper.

[0053] In an alternative embodiment, such as Figure 8-9 As shown, the outer wall of the upper cam ring 140 is provided with cam grooves 141 of varying heights along the circumferential direction, and the upper end face of the lower cam ring 240 is provided with cam surfaces 241 of varying heights along the circumferential direction. The downward protruding areas of the cam grooves 141 and the upward protruding areas of the cam surfaces 241 are both located within the axial projection area of ​​the sector magnet 151. Within the closed area of ​​the first gripper 121, the pressing mechanism 130 floats downward and the lifting mechanism 230 floats upward.

[0054] In an alternative embodiment, such as Figure 10-11 As shown, the push rod 131 is provided with a first guide rail bracket 132, a first push rod 133, and a first spring 134. The first guide rail bracket 132 is axially fixed on the turret body 10. The first push rod 133 is slidably mounted on the first guide rail bracket 132. The upper end of the first push rod 133 is provided with a first roller 135 that rolls with the cam groove 141. The lower end face of the first push rod is plugged with the push body 1. The bottom end of the first spring 134 is connected to the first push rod 133 and the top end of the first spring 134 is connected to the second turntable 112. The first spring 134 provides an upward pulling force to the first push rod 133 so that the first roller 135 always rolls along the inner upper surface of the cam groove 141.

[0055] like Figure 12-13 As shown, the upper push rod 231 is equipped with a linear bearing 232, which is connected to the fourth turntable 212 via an upper mounting plate 239. A lower fixed plate 238 is located at the bottom of the linear bearing 232, and a roller seat 233 is mounted on the bottom of the lower fixed plate 238. The roller seat 233 has a second roller 235 that rolls with the cam surface 241. The bottom end of the piston rod 236 of the linear bearing 232 is fixedly connected to the lower fixed plate 238, and the upper end of the piston rod 236 slides through the upper mounting plate 239 and is fixedly connected to the upper top plate 237, which is used to push the air chamber 2 upwards. A second spring 234 is fitted on the piston rod 236 between the upper mounting plate 239 and the lower fixed plate 238. The second spring 234 provides downward pressure to the roller seat 233, causing the second roller 235 to always roll along the upper surface of the cam surface 241.

[0056] In an optional embodiment, the turret body 10 is provided with a main body plug feeding device (not shown in the figure), which feeds the main body plug into the first opening slot on the front side of the sector magnet.

[0057] A transfer mechanism is provided at the rear of the sector magnet. This mechanism transfers the main body plug 1, which contains the air bag 2, away. Figure 1 The nozzle assembly is then transferred to the next turret for further assembly. It should be noted that the "front" and "rear" sides mentioned above refer to the front and rear sides in the turret's rotation direction.

[0058] The assembly method of the present invention is as follows:

[0059] 1. Feeding: The feeding process of the main body plug is as follows: The main body plug 1 is fed into the first open slot located in front of the sector magnet in the rotation direction by the main body plug feeding device. At this time, the solenoid valve does not sense the magnetic field, so the first gripper 121 is in the open state. The main body plug is fed into the first open slot of the first turntable 111 by the feeding mechanism on the turret. Through the convex ring 1-1 of the main body plug 1 itself (such as...) Figure 2 (As shown) can be hung on the first turntable 111. As the turret body rotates, the solenoid valve rotates into the area of ​​the sector magnet 151. The solenoid valve 151 senses the magnetic field and closes the first gripper 121 connected to it to hold the main body plug 1.

[0060] The air bag feeding process is as follows: the air bag 2 is conveyed by the air bag feeding device to the opening of the second gripper 221 at the beginning of the sector magnet, and then the second gripper 221 is closed to hold the air bag 2.

[0061] In this invention, there are various ways to control the opening and closing of the second gripper 221, including but not limited to: cam block, electric actuator program control, and linkage design with the first gripper 121. This patent does not cover the control of the second gripper 221, therefore it will not be elaborated upon here.

[0062] 2. Assembling the workpiece: Within the area of ​​the sector magnet 151, the turret body 10 rotates along the rotation path to the first position of the second half of the sector magnet's rotation. At this time, the recessed part of the upper cam ring 140 and the protruding part of the lower cam ring 240 coincide in the axial direction. The downward push rod 131 floats downward and presses against the upper end face of the main body plug 1 held by the first gripper 121. At the same time, the upward push rod 231 floats upward, lifting the air bag 2 held by the second gripper 221 and inserting it into the slot of the main body plug 1 to form a... Figure 1 The nozzle assembly. It should be noted that the second gripper 221 horizontally clamps the air bag, while the upper push rod 231 pushes the air bag 2 upward, so the upper push air bag 2 does not need to release the gripper 221.

[0063] 3. Transfer: When the solenoid valve 152 leaves the area of ​​the sector magnet 151, the first gripper 121 connected to it is opened, and the second gripper 221 corresponding to the first gripper 121 is also opened at the same time, and the receiving device removes the nozzle assembly from the turret body 10.

The turret-type assembly device for a nozzle assembly as described in claim 3, characterized in that, The turret body (10) is provided with a main body plug feeding device, which feeds the main body plug (1) into the first opening slot of the first turntable (111) located in front of the sector magnet in the rotation direction; A transfer mechanism (400) is provided on the rear side of the fan-shaped magnet in the rotation direction, and the nozzle assembly is transferred away by the transfer mechanism (400).

8. A method for assembling and transferring a turret-type assembly device using the nozzle assembly described in any one of claims 1-7, characterized in that, The method comprises three steps: loading, assembly, and transfer. The specific steps are as follows: Feeding: The main body plug (1) is fed into the first open slot located in front of the sector magnet in the rotation direction by the main body plug feeding device. The solenoid valve rotates to the area of ​​the sector magnet (151). The solenoid valve (152) senses the magnetic field and closes the first gripper (121) connected to it to clamp the main body plug (1). The air bag (2) is conveyed by the air bag feeding device to the opening of the second gripper (221) at the beginning of the sector magnet and then the second gripper (221) is closed to hold the air bag (2); Assembly: When the solenoid valve (152) rotates to the second half of the fan-shaped magnet (151), the downward push rod (131) floats down and presses against the upper end face of the main body plug (1) held by the first gripper (121), while the upward push rod (231) floats up and pushes the air bag (2) held by the second gripper (221) upward. The air bag (2) is inserted into the main body plug (1) to form the nozzle assembly. Transfer: When the solenoid valve (152) leaves the area of ​​the sector magnet (151), the first gripper (121) connected to it is opened, and the second gripper (221) corresponding to the first gripper (121) is also opened at the same time, and the nozzle assembly is removed from the turret body (10) by the receiving device.
