Technical Field

[0001] This utility model relates to the field of assembly and processing equipment technology, specifically to an automated parts assembly and engraving equipment. Background Technology

[0002] To reduce vehicle weight, achieve energy conservation and emission reduction, and lower production costs, the automotive manufacturing industry is increasingly using plastic parts in vehicle bodies. However, due to a saturated and highly competitive automotive market, cost control requirements for plastic parts are becoming more stringent. Existing plastic parts processing companies typically use injection molding and manual assembly for production. The process involves manually placing parts into assembly equipment, starting the equipment for pressing / inspection, then manually removing the assembled parts and placing them into an engraving machine for laser engraving, followed by manual removal. Because the entire production process is manual, efficiency is low, there is a risk of mixing good and defective products, and error prevention is insufficient. It's impossible to simultaneously check for spring length discrepancies and missing parts, necessitating the establishment of inspection stations and increased manpower. Therefore, the manufacturing cost of these parts remains high.

[0003] Those skilled in the art hope to propose a device that, based on existing technology, can perform both pressing / inspection and engraving of parts, while also automatically sorting out defective products, in order to reduce the manufacturing cost of parts and improve economic efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figures 1 to 10As shown, an automated parts assembly and engraving equipment includes a machine base 1, a PLC control system installed inside the machine base 1, a rotatable circular worktable 2 on the top of the machine base 1, four fixtures 3 for placing and fixing parts are equidistantly arranged on the circular worktable 2 along the radial direction, and a parts feeding station, a pressing and inspection mechanism 4, a marking and transfer mechanism 5, and a defective product moving mechanism 6 are arranged equidistantly on the machine base 1 along the rotation direction of the circular worktable 2. The pressing and inspection mechanism 4, the marking and transfer mechanism 5, and the defective product moving mechanism 6 are connected to the PLC control system via signals.

[0030] The operator manually places the parts into the tooling 3 at the parts loading station. The pressing and testing mechanism 4 is used to press and assemble the parts on the tooling 3 into finished products and to check whether the finished products are press-fitted. The marking and transfer mechanism 5 is used to laser mark the finished good products that have completed the pressing and assembly process and to transfer the marked finished good products to the good product area. The defective product moving mechanism 6 is used to move the finished defective products into the defective product box.

[0031] The press-fitting testing mechanism 4 includes a support arm 41 mounted on the machine base 1, and a cylinder 42 mounted vertically on the top of the support arm 41 via a horizontal arm. The telescopic end of the cylinder 42 passes through the horizontal arm and is provided with a press-fitting testing table 43. The bottom of the press-fitting testing table 43 is provided with a spring position sensor 44 and a press-fitting head 45. The spring position sensor 44 is configured as two sensors corresponding to the two ends of the spring respectively. The spring position sensor 44 is connected to the PLC control system signal.

[0032] When tooling 3 rotates to the position below pressing and testing mechanism 4, the extension and retraction end of cylinder 42 moves pressing and testing table 43 downward. Pressing head 45 presses the spring on tooling 3 and the part together. Spring position sensor 44 contacts the two ends of the spring to detect the height of the finished spring. The spring position sensor detects whether the spring is installed in place by detecting the spring height. The detected displacement is compared with the preset value in the PLC control system to determine whether it is a good product. If it is a good product, the circular worktable 2 rotates normally by one station and enters the next process, marking and transfer mechanism 5 for marking. If it is a defective product, the next process is skipped. The circular worktable 2 rotates by two station positions to rotate the finished defective product to the position of defective product moving mechanism 6. The defective product moving mechanism 6 moves the defective product into the defective product box.

[0033] The marking and transfer mechanism 5 includes a material picking structure 51, a marking mechanism 52, and a conveyor belt 53. The material picking structure 51 includes a vertical arm 511 mounted on the machine base 1, a cylinder 42 arranged vertically on the top side of the vertical arm 511, a horizontal linear module 512 mounted on the extension end of the cylinder 42, a swing cylinder 513 arranged on the slide of the horizontal linear module 512, a swing arm 514 mounted on the output end of the swing cylinder 513, and a pneumatic suction cup 515 arranged on the swing arm 514. The conveyor belt 53 is located below one side of the material picking structure 51, and the marking mechanism 52 is located on the other side of the conveyor belt away from the material picking structure 51.

[0034] The marking mechanism 52 is a laser marking machine.

[0035] When tooling 3 rotates to the marking and transfer mechanism 5, the telescopic end of cylinder 42 extends downward, driving the pneumatic suction cup 515 to move down and pick up the part. Then, the telescopic end of cylinder 42 retracts upward to return to its original position. The output end of swing cylinder 513 rotates to rotate swing arm 514, causing the part picked up by pneumatic suction cup 515 to rotate 90 degrees and move to the marking height of the laser marking machine. The marking mechanism 52 prints a mark on the part. The slide of horizontal linear module 512 moves towards the conveyor belt 53. Pneumatic suction cup 515 moves synchronously with the slide above the conveyor belt 53. Pneumatic suction cup 515 releases the part, and the part falls onto the conveyor belt 53.

[0036] The defective product moving mechanism 6 includes a U-shaped arm 61, a horizontal cylinder 62, a vertical cylinder 63, and a defective product pneumatic suction cup 64 mounted on the machine base 1. The extension line of the horizontal arm of the U-shaped arm 61 intersects the top surface of the circular worktable 2. The horizontal cylinder 62 is located at the top of the horizontal arm of the U-shaped arm 61 along the length of the horizontal arm. The vertical cylinder 63 is installed at the telescopic end of the horizontal cylinder 62 along the vertical direction. The defective product pneumatic suction cup 64 is located at the telescopic end of the vertical cylinder 63. A defective product discharge port 65 is provided on the machine base 1 between the two vertical arms of the U-shaped arm 61. The defective product discharge port 65 is connected to the defective product box through a pipe.

[0037] When the fixture 3 rotates to the position of the defective product moving mechanism 6, the telescopic end of the horizontal cylinder 62 extends above the fixture 3, and the telescopic end of the vertical cylinder 63 moves to drive the defective product pneumatic suction cup 64 to move down and pick up the finished defective product. The telescopic end of the vertical cylinder 63 retracts to drive the finished defective product away from the fixture 3. The telescopic end of the horizontal cylinder 62 retracts to drive the defective product pneumatic suction cup 64 to move above the defective product discharge port 65. The defective product pneumatic suction cup 64 releases the finished defective product, so that the finished defective product falls into the defective product box through the defective product discharge port 65.

[0038] A frame structure 7 is installed on the machine base 1, and a baffle 8 is covered on the frame structure 7.

[0039] The baffle 8 is equipped with a human-machine interface panel 9, which is connected to the PLC control system.

[0040] An audible and visual alarm 10 is installed on the baffle 8 at the top of the frame structure 7.

[0041] A grating sensor 11 is installed at the parts loading station of machine 1. The grating sensor 11 is connected to the PLC control system signal and is used to sense the actions of the operator.
