Description

Technical Field

[0001] This utility model relates to the field of spring assembly technology, specifically a flexible feeding spring assembly machine. Background Technology

[0002] A positioning ball, also known as a positioning pin, positioning ball screw, or ball plunger, is a mechanical fastener primarily used for precise positioning, fixing, or aligning of parts. It mainly consists of a positioning ball spring and a ball bearing. The positioning ball spring refers to the combination of the housing and the internal spring; however, the positioning ball spring and the ball bearing need to be assembled during production.

[0003] Currently, the existing positioning beads are all assembled manually, with a low degree of automation in the assembly process. This increases labor intensity and reduces work efficiency. Moreover, the existing positioning beads are prone to mixing good and defective products during assembly, thus reducing the yield rate. Utility Model Content

[0004] The purpose of this invention is to provide a flexible feeding spring assembly machine to solve the problems mentioned in the background art, such as low efficiency of manual assembly and the easy mixing of good and bad products, resulting in a low yield rate.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible feeding spring assembly machine, comprising a frame, a control panel mounted on the surface of the frame for controlling the entire assembly machine; a positioning bead spring feeding mechanism and a ball feeding mechanism mounted side-by-side on one side of the frame surface, a transfer mechanism for feeding balls mounted on one side of the ball feeding mechanism, and an assembly mechanism for assembling the positioning bead spring and the ball on one side of the transfer mechanism; a robot mounted on the surface of the frame for transporting the positioning bead spring from the positioning bead spring feeding mechanism to the assembly mechanism; and a visual testing mechanism mounted on one side of the assembly mechanism for visual inspection after the positioning bead spring and the ball are assembled.

The sorting feeder is used to vibrate the balls into the buffer hopper, and the cleaning assembly is used to receive the balls during cleaning of the buffer hopper.

[0008] Preferably, two sets of feeding CCD cameras are installed on the top surface of the frame, and the two feeding CCD cameras are located directly above the buffer tray and the buffer hopper, respectively. The feeding CCD cameras are used for visual photography of the products on the surface of the buffer tray and the buffer hopper.

[0009] Preferably, the transplanting mechanism includes a three-axis manipulator and a cylinder gripper. The three-axis manipulator is fixed to the surface of the frame, and the output end of the three-axis manipulator is equipped with two sets of cylinder grippers. The two sets of cylinder grippers respectively feed the balls in the buffer bin to the assembly mechanism, transport the assembled products in the assembly mechanism to the visual testing mechanism, and place the products inspected by the visual testing mechanism into the good product box or the defective product box.

[0010] Preferably, the visual testing mechanism consists of a carrier, a cylinder chuck, and an assembled CCD camera. The carrier is fixed to the surface of the frame, and a cylinder chuck is installed on one side of the top of the carrier.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This flexible feeding spring assembly machine feeds positioning bead springs and balls respectively through a positioning bead spring feeding mechanism and a ball feeding mechanism. Then, a robot transports the positioning bead springs from the positioning bead spring feeding mechanism to the assembly mechanism. Subsequently, a transfer mechanism feeds the balls from the ball feeding mechanism to the assembly mechanism, which then performs assembly. After assembly, the transfer mechanism transports the assembled products to a visual testing mechanism for quality inspection. After inspection, the transfer mechanism places good and defective products into good or defective product boxes respectively. This utility model, by setting up a positioning bead spring feeding mechanism, a ball feeding mechanism, a robot, a transfer mechanism, and an assembly mechanism, achieves automatic feeding and assembly functions, improving the automation level of assembly.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The structure of the flexible feeding spring assembly machine provided by this utility model is as follows: Figure 1 as well as Figure 3As shown, the assembly includes a frame 1, on the surface of which a control panel 11 is mounted. This control panel 11 is used for controlling the entire assembly machine. On one side of the frame 1, a positioning bead spring feeding mechanism 2 and a ball feeding mechanism 3 are mounted side-by-side. The positioning bead spring feeding mechanism 2 includes a flexible vibrating plate 21 and a buffer tray 22. The flexible vibrating plate 21 and the buffer tray 22 are mounted on the surface of the frame 1. The flexible vibrating plate 21 is used to flexibly vibrate the positioning bead spring products into the buffer tray 22. The ball feeding mechanism 3 is fixed to the machine... The frame 1 consists of a sorting feeder 31, a buffer hopper 32, and a cleaning assembly 33. The sorting feeder 31 is used to vibrate the balls into the buffer hopper 32. The cleaning assembly 33 is used to receive the material during the cleaning of the buffer hopper 32. Two sets of feeding CCD cameras 12 are installed on the top surface of the frame 1. The two feeding CCD cameras 12 are located directly above the buffer tray 22 and the buffer hopper 32, respectively. The feeding CCD cameras 12 are used for visual photography of the products on the surface of the buffer tray 22 and the buffer hopper 32, respectively.

[0022] During implementation, the positioning bead spring and the ball are conveyed to the buffer tray 22 and the buffer hopper 32 respectively through the flexible vibrating plate 21 and the sorting feeder 31. At this time, the feeding CCD camera 12 takes visual pictures of the products in the buffer tray 22 and the buffer hopper 32.

[0023] Furthermore, such as Figure 2 as well as Figure 5 As shown, a transfer mechanism 5 for feeding marbles is installed on one side of the marble feeding mechanism 3. The transfer mechanism 5 includes a three-axis robot 51 and a cylinder gripper 52. The three-axis robot 51 is fixed to the surface of the frame 1, and two sets of cylinder grippers 52 are installed at the output end of the three-axis robot 51. The two sets of cylinder grippers 52 feed the marbles in the buffer bin 32 to the assembly mechanism 7, and transport the assembled products in the assembly mechanism 7 to the vision testing mechanism 6. Then, the products inspected by the vision testing mechanism 6 are placed into the good product box or the defective product box.

[0024] During implementation, after assembly, the cylinder gripper 52 holds the product and, driven by the three-axis robot arm 51, it enters the cylinder chuck 62 and is held.

[0025] Furthermore, such as Figure 3 as well as Figure 4As shown, an assembly mechanism 7 for assembling the positioning bead spring and the ball is provided on one side of the transplanting mechanism 5. The assembly mechanism 7 includes a support frame 71, a cylinder clamp 72, a cylinder pressure plate 73, and a cylinder push rod 74. The support frame 71 is fixed to the surface of the frame 1. The cylinder clamp 72 is installed on the surface of the support frame 71. The cylinder clamp 72 is used to clamp the ball. The cylinder push rod 74 is installed on the top of the support frame 71. The cylinder push rod 74 is used to push the positioning bead spring toward the ball to complete the assembly. The cylinder pressure plate 73 is installed at one end of the surface of the support frame 71. The cylinder pressure plate 73 is used to block the assembly process.

[0026] During implementation, the robot 4 clamps the positioning ball spring in the buffer tray 22 into the support frame 71, while the ball in the buffer bin 32 is clamped into the cylinder clamp seat 72 by the three-axis robot 51 driving the cylinder gripper 52. After the cylinder clamp seat 72 clamps, the cylinder pressure plate 73 blocks the positioning ball spring from moving upward. Then, the cylinder push rod 74 presses the positioning ball spring and the ball together.

[0027] Furthermore, such as Figure 2 as well as Figure 4 As shown, a robot 4 is mounted on the surface of the frame 1. The robot 4 is used to transport the positioning bead spring in the positioning bead spring feeding mechanism 2 to the assembly mechanism 7. A vision testing mechanism 6 is provided on one side of the assembly mechanism 7. The vision testing mechanism 6 is used for visual inspection after the positioning bead spring and the ball are assembled. The vision testing mechanism 6 consists of a carrier 61, a cylinder chuck 62 and an assembly CCD camera 63. The carrier 61 is fixed to the surface of the frame 1, and a cylinder chuck 62 is mounted on one side of the top of the carrier 61. The assembly CCD camera 63 is mounted on the top of the carrier 61 through a bracket. The assembly CCD camera 63 is used for inspection after assembly.

[0028] During implementation, the assembly qualification is checked by assembling a CCD camera 63. The product with the cover closed is held by the cylinder gripper 52 and enters the good product box under the drive of the three-axis robot arm 51, while the defective product will enter the defective product box.

[0029] Working principle: In use, the positioning bead spring and the ball are first fed by the positioning bead spring feeding mechanism 2 and the ball feeding mechanism 3 respectively. Then, the robot 4 transports the positioning bead spring in the positioning bead spring feeding mechanism 2 to the assembly mechanism 7. Subsequently, the transfer mechanism 5 feeds the ball in the ball feeding mechanism 3 to the assembly mechanism 7. The assembly mechanism 7 is used to realize the assembly. After assembly, the transfer mechanism 5 transports the assembled product to the visual testing mechanism 6 for qualified inspection. After the inspection is completed, the transfer mechanism 5 puts the good products and defective products into the good product box or the defective product box respectively.

[0030] Specifically, the positioning bead spring and the ball are conveyed to the buffer tray 22 and the buffer bin 32 respectively through the flexible vibrating plate 21 and the sorting feeder 31. At this time, the feeding CCD camera 12 takes visual pictures of the products in the buffer tray 22 and the buffer bin 32. Then, the robot 4 clamps the positioning bead spring in the buffer tray 22 into the support frame 71, while the ball in the buffer bin 32 is clamped into the cylinder clamp seat 72 by the three-axis robot 51 driven by the cylinder gripper 52. After the cylinder clamp seat 72 clamps, the cylinder pressure plate 73 blocks the positioning bead spring from moving upward. Then, the cylinder push rod 74 presses the positioning bead spring and the ball together.

[0031] After assembly, the cylinder gripper 52 holds the product and, driven by the three-axis robot 51, it enters the cylinder chuck 62 and is held in place. At this time, the assembly CCD camera 63 performs a qualification test on the assembled product. The product with the cover closed is held by the cylinder gripper 52 and enters the good product box under the drive of the three-axis robot 51, while the defective product enters the defective product box.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
