Description

Technical Field

[0001] This invention relates to the field of O-rings, and in particular to a semi-automatic assembly machine for bracelet-type O-rings. Background Technology

[0002] With the development of industrial automation, traditional manual assembly methods are gradually being replaced by automated equipment. Before widespread application, the production volume of many products is relatively small. Many of these products require the assembly of bracelet-type O-rings for sealing. The semi-automatic assembly machine for bracelet-type O-rings has emerged to address this need. By changing some parts, the machine can be used to assemble multiple types of O-rings, which can reduce labor intensity to a certain extent, ensure product quality consistency, and improve production efficiency. However, some bracelet-type O-rings require the uniform application of various types of grease or are inherently sticky, making it impossible to automatically feed them sequentially using a vibratory feeder. Therefore, the semi-automatic assembly machine for bracelet-type O-rings was proposed. Summary of the Invention

[0003] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0004] A semi-automatic assembly machine for bracelet-type O-rings includes a base plate. A ring-holding rod with multiple bracelet-type O-rings is mounted on one side of the base plate, with the O-rings arranged equidistantly on the outside of the rod. One end of the rod is fitted with a workpiece to be assembled with the bracelet-type O-rings. A positioning and clamping mechanism is provided on one side of the base plate to position the ring-holding rod. An assembly mechanism is provided on one side of the positioning and clamping mechanism to sequentially assemble the multiple bracelet-type O-rings onto the workpiece. The assembly mechanism is located above the base plate. An injection mechanism for injecting lubricating oil into the bracelet-type O-rings is provided on one side of the positioning and clamping mechanism.

[0005] Preferably, the positioning and pressing mechanism includes a fixed plate vertically mounted on the base plate, with one end of the collar rod passing through the fixed plate. A positioning block is horizontally mounted at the lower end of the back of the fixed plate, and a pressing block is mounted above the positioning block, which is opposite to it. A positioning cylinder is mounted at the upper end of the back of the fixed plate to drive the pressing block and the positioning block to close / separate.

[0006] Preferably, the assembly mechanism includes a movable platform that is laterally movable above the base plate, and a gripper cylinder that moves synchronously with the movable platform is vertically arranged on one side above the movable platform. The upper end of the gripper cylinder is driven to have a gripper for closing / separating the other end of the ring rod. The gripping surfaces of the gripper are all located at the gap between the bracelet-type O-rings. An assembly cylinder is arranged on the side away from the movable platform, and the assembly cylinder is laterally located above the base plate. The assembly cylinder is driven to connect with the movable platform. An O-ring sensor for sensing the position of the bracelet-type O-rings is arranged on the side away from the gripper.

[0007] Preferably, the assembly mechanism further includes a lead screw drive gearbox located on one side of the assembly cylinder, the lead screw drive gearbox being vertically positioned on the base plate, and a servo motor connected to the lead screw drive gearbox being located on one side of the lead screw drive gearbox facing forward, and a lead screw connected to the lead screw drive gearbox being located on the other side of the lead screw drive gearbox, with a movable plate cooperating with the lead screw drive. The movable plate is horizontally mounted on the base plate, and a connecting block that moves synchronously with the movable plate is located at the other end of the movable plate, and a pusher plate that moves synchronously with the connecting block and is fitted onto the outside of the ring rod is located at the other end of the connecting block.

[0008] Preferably, one end of the collar rod is formed with a collar rod positioning notch for easy positioning. The positioning notch ensures that the positioning and clamping mechanism keeps the one end of the collar rod stable when clamping it. The other end of the collar rod is provided with a workpiece mounting block for installing and fixing the workpiece. The connection between the workpiece mounting block and the collar rod is formed with a positioning hole for positioning the bracelet-type O-ring.

[0009] Preferably, one end of the workpiece is inserted into the other end of the workpiece mounting block, and the outside of the workpiece mounting block has a second sloping surface.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when multiple bracelet-type O-rings are fitted onto the outside of the ring rod and the ring rod is manually placed horizontally on the base plate, the positioning and clamping mechanism clamps one end of the ring rod, and at the same time, the assembly mechanism pushes out the multiple bracelet-type O-rings on the ring rod in sequence and pushes them onto the workpiece at the other end of the ring rod, thereby fitting the bracelet-type O-rings onto the workpiece. Furthermore, if bracelet-type O-rings of different diameters need to be assembled, it is only necessary to replace the ring rod with one that matches the diameter of the bracelet-type O-ring.

[0013] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-5 In this embodiment of the invention, a semi-automatic assembly machine for bracelet-type O-rings includes a base plate 6. A ring-holding rod 11, on one side of the base plate 6, is mounted on a horizontal frame for mounting multiple bracelet-type O-rings. The multiple bracelet-type O-rings are equidistantly distributed outside the ring-holding rod 11. One end of the ring-holding rod 11 is inserted into a workpiece 4 for assembly with the bracelet-type O-rings. A positioning and clamping mechanism is provided on one side of the base plate 6 to position and hold the ring-holding rod 11 horizontally. An assembly mechanism is provided on one side of the positioning and clamping mechanism to sequentially assemble the multiple bracelet-type O-rings outside the ring-holding rod 11 onto the workpiece 4. The assembly mechanism is mounted on the base plate 1. An injection mechanism for injecting lubricating oil into the bracelet-type O-rings is provided on one side of the positioning and clamping mechanism. When multiple bracelet-type O-rings are fitted onto the outside of the collar rod 11 and the collar rod 11 is manually placed horizontally on the base plate 1, the positioning and clamping mechanism clamps one end of the collar rod 11. At the same time, the assembly mechanism pushes out the multiple bracelet-type O-rings on the collar rod 11 in sequence and pushes them onto the workpiece 4 at the other end of the collar rod 11, thereby fitting the bracelet-type O-rings onto the workpiece 4. If bracelet-type O-rings of different diameters need to be assembled, it is only necessary to replace the collar rod 11 with one that matches the diameter of the bracelet-type O-ring.

[0023] The positioning and clamping mechanism includes a fixed plate 13 vertically mounted on the base plate 6, with one end of the collar rod 11 passing through the fixed plate 13. A positioning block 16 is horizontally arranged at the lower end of the back of the fixed plate 13, and a pressure block 15 is arranged above the positioning block 16. A positioning cylinder 14 is arranged at the upper end of the back of the fixed plate 13 to drive the pressure block 15 and the positioning block 16 to close / separate. When one end of the collar rod 11, which is fitted with multiple bracelet-type O-rings, passes through the fixed plate 13 and is located on the positioning block 16, the positioning cylinder 14 drives the pressure block 15 and the positioning block 16 to close, thereby clamping one end of the collar rod 11. This allows the collar rod 11 to be horizontally mounted on the base plate 6, so that the subsequent assembly mechanism can sequentially push the multiple bracelet-type O-rings on the collar rod 11 onto the workpiece 4 at the other end of the collar rod 11.

[0024] The assembly mechanism includes a movable platform 10 that is laterally movable above the base plate 6. A gripper cylinder 24, moving synchronously with the movable platform 10, is vertically mounted on one side above it. The upper end of the gripper cylinder 24 is driven by grippers 23 that close / separate the other end of the ring rod 11. The gripping surfaces of the grippers 23 are located at the gaps between the bracelet-type O-rings. An assembly cylinder 21 is mounted on the side away from the movable platform 10, and is laterally positioned above the base plate 6. The assembly cylinder 21 and the movable platform 10 are positioned... The drive connection is made, and an O-ring sensor 22 is provided on the side away from the gripper 23 to sense the position of the hand-beaded O-ring. When the O-ring sensor 22 senses the hand-beaded O-ring, the gripper cylinder 24 drives the gripper 23 to close to both sides at the other end of the collar rod 11 and insert it into the gap between the hand-beaded O-rings. At the same time, the assembly cylinder 21 drives the moving table 10 to move horizontally on the base plate 6, thereby pushing and fitting multiple hand-beaded O-rings fitted on the collar rod 11 onto the workpiece 4 at the other end of the collar rod 11 in sequence.

[0025] The assembly mechanism also includes a lead screw drive gearbox 18 located on one side of the assembly cylinder 21, and the lead screw drive gearbox 18 is vertically positioned on the base plate 6. A servo motor 17 is connected to the lead screw drive gearbox 18 on its front side, and a lead screw (not shown in the figure) is connected to the lead screw drive gearbox 18 on its other front side. A movable plate 8 is connected to the lead screw drive gearbox 18, and the movable plate 8 is horizontally mounted on the base plate 6. A connecting block 19 that moves synchronously with the movable plate 8 is located at the other end of the movable plate 8. At the other end, there is a pusher platform 20 that moves synchronously with it and is fitted outside the collar rod 11. When the servo motor 17 drives the lead screw transmission gearbox 18 to rotate along with the lead screw, the lead screw, along with the moving plate 8, the connecting block 19 and the pusher platform 20, moves horizontally above the base plate 6. This causes the pusher platform 20 to move horizontally outside the collar rod 11, thereby pushing multiple bracelet-type O-rings 12 on the collar rod 11 to the other end of the collar rod 11 in sequence. This allows the bracelet-type O-rings 12 at the other end of the collar rod 11 to be fitted onto the workpiece 4 in sequence.

[0026] One end of the collar rod 11 is formed with a collar rod positioning notch 26 for easy positioning. The collar rod positioning notch 26 makes the positioning and clamping mechanism stable when clamping one end of the collar rod 11. The other end of the collar rod 11 is provided with a workpiece mounting block 29 for mounting and fixing the workpiece 4. The connection between the workpiece mounting block 29 and the collar rod 11 is formed with a positioning hole 28 for positioning the bracelet-type O-ring 12. When the bracelet-type O-ring 12 is located at the positioning hole 28, the O-ring sensor 22 can sense the bracelet-type O-ring 12. The connection surface between the workpiece mounting block 29 and the collar rod 11 is a first slope surface 27, which makes it more convenient to push the bracelet-type O-ring 12 from the collar rod 11 onto the workpiece mounting block 29.

[0027] One end of the workpiece 4 is inserted into the other end of the workpiece mounting block 29, and the outside of the workpiece mounting block 29 is a second slope surface (not shown in the figure). The other end of the workpiece mounting block 29 is also provided with a product sensor 25 for sensing the position of the workpiece 4. The second slope surface makes it more convenient to push the bracelet-type O-ring 12 from the workpiece mounting block 29 onto the workpiece 4.

[0028] The oil injection mechanism includes an oil extraction device 7 mounted on the base plate 6, and the oil extraction device 7 is connected to an injection head (not shown in the figure) located on one side of the collar rod 11. Thus, through the cooperation of the oil extraction device 7 and the injection head, lubricating oil can be injected onto multiple bracelet-type O-rings on the outside of the collar rod 11.

[0029] The base plate 6 is covered with a machine housing 1, and an oil can 5 connected to the oiling mechanism is provided on one side above the machine housing 1. A touch screen 2 is vertically provided on the front side of the machine housing 1, and a control button 3 is provided below the touch screen 2 away from it. The touch screen 2 and the control button 3 are electrically connected to the positioning and pressing mechanism and the assembly mechanism, respectively.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
