[0002] In the existing automobile hood lock assembly device, after assembling the various components of the automobile hood lock assembly, the automobile hood lock assembly includes a bottom shell, rivets, springs, and an upper cover. During assembly, the bottom shell, rivets, and springs are usually assembled in sequence, and finally the upper cover is placed on top of the spring. Because the spring usually needs to be compressed in advance, the assembled automobile hood lock assembly needs to be transported to the riveting process. The top of the rivet on which the spring is mounted is riveted flat to form a riveted surface that limits the compressed spring before the final assembly of the automobile hood lock assembly can be completed. During the process of transporting the automobile hood lock assembly to the riveting process, the pre-compressed spring has a tendency to reset itself, which can easily lift up the upper cover of the automobile hood lock assembly, causing the position of the upper cover to interfere with the rivet head of the riveting process, affecting the riveting effect.

[0030] The pressing assembly 42 includes a mounting frame 421, a clamping plate 423 and a lifting cylinder 422 arranged on the mounting frame 421. The mounting frame 421 is arranged on the rotating disk 20. The cylinder body of the lifting cylinder 422 is fixedly connected to the vertical portion 411 of the carrier 41. The clamping plate 423 and the piston rod of the lifting cylinder 422 are fixedly connected. The lifting cylinder 422 controls the lifting and lowering of the clamping plate 423 to press the upper cover and the spring. The middle part of the clamping plate 90 is provided with a rivet hole 91 corresponding to the rivet in the automobile front cover lock assembly 200.

[0031] The riveting machine 50 is used to flush the top of the rivet. The riveting machine 50 is provided with a rivet head 51. The rivet head 51 corresponds to the rivet hole 91. The rivet head 51 flushes the rivet in the automobile hood lock assembly 200 through the rivet hole 91. Specifically, in this embodiment, the specific structure of the riveting machine 50 is conventional and will not be described in detail in this embodiment.

[0032] Detection assembly 60 includes a support frame 61, a second lift cylinder 62, and a displacement sensor 63. Support frame 61 is fixedly mounted on frame 10, and second lift cylinder 62 is mounted on support frame 61. Displacement sensor 63 is fixedly connected to the piston rod of second lift cylinder 62.

Specifically, the extension direction of the X-axis cylinder 72 is set along the diameter direction of the rotating disk 20, and the extension direction of the Y-axis cylinder 74 is set along the thickness direction of the rotating disk 20.

[0034] The working process of the automobile front cover lock assembly device 100 provided by the utility model is as follows: Figure 1 ,by Figure 1 The position of the carrier 41 shown is the initial position. At this position, the spring and bottom shell, rivet and upper cover of corresponding length placed in the placement rack 111 will be assembled on the carrier 41. After the assembly is completed, the lifting cylinder 80 will be started to move the clamping plate 90 downward to compress the spring to a compressed state, and at the same time allow the rivet to pass through the rivet hole 91 on the clamping plate 90 to complete the assembly process.

[0035] Please refer to Figure 2 Then, the drive module 30 is activated, controlling the rotating disk 20 to rotate the compressed automobile hood lock assembly 200 to the riveting machine 50, and making the top of the rivet face the rivet head 51 of the riveting machine 50. The riveting machine 50 is then started to rivet the rivet until the top of the rivet is riveted flat and the top of the rivet limits the compressed spring. The rivet head 51 of the riveting machine 50 is then removed to complete the riveting process.

[0036] Please refer to Figure 3 Then, the drive module 30 is started, and the rotating disk 20 is controlled to rotate the finally assembled automobile hood lock assembly 200 to the detection assembly 60, so that the top of the rivet is facing the measuring head of the displacement sensor 63. Then, the lifting cylinder 2 62 is started to move the displacement sensor 63 downward until the measuring head of the displacement sensor 63 moves to the pre-set standard height of the rivet top after it is riveted flat. If the top of the rivet does not contact the measuring head of the displacement sensor 63 or the measuring head of the displacement sensor 63 is compressed, the height of the rivet top does not meet the requirements, and the drive module 30 is started to rotate the automobile hood lock assembly 200 to the pre-processing step for reprocessing; if the top of the rivet just contacts the measuring head of the displacement sensor 63, the height of the rivet top meets the requirements and the detection process is completed.

[0037] Please refer to Figure 4 The drive module 30 is then activated to rotate the inspected and qualified hood lock assembly 200 to the blanking plate 75. The lift cylinder 80 is then activated to raise the pressure plate 90, releasing the pressure on the hood lock assembly 200. The X-axis cylinder 72 is then activated to move the electric gripper 76 away from the hood lock assembly 200. The Y-axis cylinder 74 is then activated to lower the electric gripper 76 until it reaches a suitable height for gripping the hood lock assembly 200. The X-axis cylinder 72 is then controlled to move the electric gripper 76 toward the hood lock assembly 200 and simultaneously activated to clamp the hood lock assembly 200. The X-axis cylinder 72 and Y-axis cylinder 74 then coordinate to control the electric gripper 76 to grip the hood lock assembly 200 and move it above the blanking plate 75. The hood lock assembly 200 is then placed on the blanking plate 75, completing the blanking process.

[0038] Example 2

[0039] Please refer to Figure 5 This embodiment differs from the first embodiment in that the blanking plate 75 and the frame 10 can also be slidably connected. The blanking assembly 70 further includes a slide rail 77 and a telescopic cylinder 78 provided on the frame 10. The blanking plate 75 is provided with a sliding block. The piston rod of the telescopic cylinder 78 is fixedly connected to the sliding block, and the sliding block is slidably mounted on the slide rail 77 via the telescopic cylinder 78. When the position of the blanking plate 75 on the frame 10 needs to be adjusted, the telescopic cylinder 78 is activated, causing the blanking plate 75 to slide along the slide rail 77 until it moves to the desired position.

[0040] The beneficial effect of the present invention is that the upper cover and the spring are compressed by arranging a pressing assembly 42 that moves together with the automobile front cover lock assembly 200, so that the spring can always be kept in a compressed state during the process of being transmitted to the riveting process, and it is not easy to lift the upper cover to cause the position of the upper cover to change and interfere with the riveting position of the riveting machine 50, thereby improving the riveting effect.
