Description

Technical Field

[0001] This invention relates to the field of automotive door lock assembly and testing technology, and in particular to a cover plate clamping mechanism for an automotive door lock assembly and testing production line. Background Technology

[0002] Currently, most auto parts manufacturers use assembly line production, but this method still requires a lot of manual assembly, which is not only time-consuming and labor-intensive, but also has low production efficiency and high defect rate. Moreover, with the expansion of the automotive market, the demand for automotive door lock parts is also increasing, making it urgent to have an automated device to replace manual production. Summary of the Invention

[0003] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides a cover plate clamping mechanism for automotive door lock assembly and testing production lines, which can automatically complete the cover plate clamping task, save labor costs, and improve work efficiency.

[0004] Technical solution: The present invention provides a cover plate clamping mechanism for an automotive door lock assembly and testing production line, characterized in that it includes a fixed plate, a clamping cylinder, grippers, a cover plate contour block, a spring, a positioning pin, a detection pin, a sensor transmitting end, a sensor receiving end, and a cover plate; the clamping cylinder and the cover plate contour block are fixed on the fixed plate, the clamping cylinder is located above the cover plate contour block, and the two grippers are located on both sides of the cover plate contour block.

[0005] The cover plate conforming block has three cylindrical cavities inside. The middle cylindrical cavity contains a spring and a detection needle, while the other two cylindrical cavities contain springs and positioning needles.

[0006] The detection needle and the positioning needle are both variable cross-section cylinders. The diameter of the upper part of the cylinder is equal to that of the cylindrical cavity, while the diameter of the lower part of the cylinder is smaller than that of the cylindrical cavity. When the clamping mechanism presses down to contact the cover plate, the detection needle is compressed and the positioning needle enters the positioning hole on the cover plate.

[0007] The sensor emitting end and the sensor receiving end are respectively located inside the two grippers and on both sides of the detection needle. The cover plate contour block has a channel for the light emitted by the sensor emitting end to pass through.

[0008] Before the detection needle is compressed, the light cannot pass through due to the obstruction of the upper cylinder of the detection needle; after the detection needle is compressed, the light passes through the gap between the lower cylinder of the detection needle and the cylindrical cavity, and is received by the sensor receiving end.

[0009] The clamping cylinder controls two grippers to move relative to each other. After the sensor receives light, the clamping cylinder drives the two grippers to move in the corresponding direction, so that the grippers can grasp the cover plate.

[0010] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: When the clamping mechanism of this invention presses down, the detection needle is compressed by the cover plate. The light emitted from the sensor's emitting end is no longer obstructed by the detection needle and is received by the receiving end. The sensor sends a signal, and the gripper cylinder drives the gripper to grab the cover plate, thus completing the clamping task. This replaces manual labor for gripping cover plates on door lock assembly lines, reducing labor costs and defect rates, and improving production efficiency and automation. It enables automatic feeding of automotive door lock cover plates, allowing for uninterrupted operation. It can fully automate the clamping task of cover plates, saving labor costs and improving work efficiency. Attached Figure Description

Detailed Implementation

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0017] like Figure 1As shown, the car door lock cover plate clamping mechanism of the present invention includes a fixed plate 1, a clamping cylinder 2, grippers 3, a cover plate contour block 4, a spring 5, a positioning pin 6, a detection pin 7, a sensor transmitting end 8, a sensor receiving end 9, and a cover plate 10. The clamping cylinder 2 and the cover plate contour block 4 are fixed on the fixed plate 1, with the clamping cylinder 2 located above the cover plate contour block 4. The two grippers 3 are located on both sides of the cover plate contour block 4. The sensor transmitting end 8 and the sensor receiving end 9 are respectively placed inside the two grippers 3, and positioned... On both sides of the detection needle 7, the light emitted by the sensor emitting end 8 is blocked by the detection needle 7 in the channel of the cover plate contour block 4, and the sensor receiving end 9 cannot receive it. When the clamping mechanism presses down, the detection needle 7 is blocked by the cover plate 10, the spring 5 is compressed, and the light emitted by the sensor emitting end 8 passes through the gap between the cylinder and the cylindrical cavity in the lower part of the detection needle 7 and is received by the sensor receiving end 9. The sensor sends a signal, and the gripper cylinder 2 drives the gripper 3 to grab the cover plate 10, thereby completing the clamping task.

[0018] like Figure 2 As shown, the internal structure of the cover plate contour block of the present invention has three cylindrical cavities inside the cover plate contour block 4. The middle cavity contains a spring 5 and a detection needle 7, and the other two cavity contains a spring 5 and a positioning needle 6. Both the detection needle 7 and the positioning needle 6 are variable cross-section cylinders. The diameter of the upper cylinder is equal to that of the cylindrical cavity, and the diameter of the lower cylinder is smaller than that of the cylindrical cavity. When the clamping mechanism presses down and contacts the cover plate, the spring 5 and the detection needle 7 are compressed. The light emitted by the sensor emitting end 8 can pass through the channel 11 of the cover plate contour block 4 and through the gap between the lower cylinder of the detection needle 7 and the cylindrical cavity, and be received by the sensor receiving end 9. The positioning needle 6 enters the positioning hole on the cover plate 10, which plays the role of positioning and fixing the cover plate.

[0019] like Figure 3 As shown, the main gripping structure of the cover plate clamping mechanism of the present invention has a sensor emitting end 8 and a sensor receiving end 9 placed inside the two grippers 3 respectively. The sensor emitting end 8 emits light 12, which is received by the sensor receiving end 9. The gripping cylinder 2 controls the two grippers 3 to move in the corresponding direction, so that the grippers 3 can grip the cover plate 10 and complete the gripping task.

[0020] When the clamping mechanism of this invention presses down, the detection needle is compressed by the cover plate. The light emitted from the sensor's emitting end, no longer obstructed by the detection needle, is received by the receiving end. The sensor sends a signal, and the gripper cylinder drives the gripper to grasp the cover plate, thus completing the clamping task. This replaces manual labor for gripping cover plates on door lock assembly lines, reducing labor costs and defect rates, and improving production efficiency and automation. It enables automatic feeding of automotive door lock cover plates, allowing for uninterrupted operation. It can fully automate the clamping task of cover plates, saving labor costs and improving work efficiency.
