Description

Technical Field

[0001] The present invention relates to the technical field of automotive component assembly, and particularly to a semi-automatic inspection and assembly machine for automotive headlight assemblies. Background Art

[0002] Currently, the assembly of automotive headlight assemblies mostly relies on manual operations, and there are the following problems: 1) Low manual assembly efficiency and high costs; 2) Key parameters such as the tightening depth of screws and the installation angle of wire harnesses are difficult to precisely control, resulting in a low product qualification rate; 3) Manual inspection is prone to missed inspections or misjudgments, and the work efficiency is relatively low. At the same time, some existing automated equipment also has problems such as complex structures and is difficult to meet the requirements of multi-process collaborative operations. Summary of the Invention

[0003] The purpose of the present invention is to provide a semi-automatic inspection and assembly machine for automotive headlight assemblies, which has the characteristics of both high product qualification rate and high production efficiency.

[0033] 14. Semi-automatic wire harness installation mechanism. Detailed implementation mode

[0034] For the embodiment, see Figures 1 to 3 As shown: The semi-automatic detection and assembly machine for automotive headlight assemblies includes a frame 6. Casters 7 are provided at the bottom of the frame 6, a pneumatic and electrical quick connector 13 is provided in the middle, and components such as a fluorescent lamp 1 and a vertical arm mechanism 8 are integrated at the top. The vertical arm mechanism is used to adjust the spatial position of the following electric screwdriver 3 so that the movement of the electric screwdriver 3 maintains a certain perpendicularity, and the pneumatic and electrical quick connector 13 is used to quickly connect the air circuit and the circuit.

[0035] Furthermore:

[0036] There are two working stations on the frame 6, namely the first working station 61 on the left side shown in Figure 1 and the second working station 62 on the right side.

[0037] A first support tooling 611 for clamping the product and an automatic screw driving mechanism 12 for screwing in screws are provided on the first working station 61. The automatic screw driving mechanism 12 is equipped with a screw presence / absence detection sensor and a screw driving depth sensor.

[0038] A second support tooling 621 for clamping the product and a semi-automatic wire harness installation mechanism 14 for pressing in the wire harness are provided on the second working station 62.

[0039] Both the first support tooling 611 and the second support tooling 621 are matched with a product locking cylinder 10, and the product locking cylinder 10 is equipped with a product presence / absence detection sensor 11. The product presence / absence detection sensor 11 can be an optoelectronic sensor and can be installed at the bottom of the positioning groove and other parts of the corresponding tooling. That is, after the product presence / absence detection sensor 11 detects that the product is in place, it sends an action instruction to the product locking cylinder 10. After the product locking cylinder 10 acts, the first support tooling 611 and the second support tooling 621 clamp the corresponding product.

[0040] A control electric box 9 for realizing multi-process collaborative control is also provided on the frame 6, and the control electric box 9 has a start button 5. Obviously, the aforementioned screw presence / absence detection sensor, screw driving depth sensor, and product presence / absence detection sensor 11 are all signal-connected to the control electric box 9, and the control electric box 9 is signal-connected to the product locking cylinder 10, the automatic screw driving mechanism 12, and the semi-automatic wire harness installation mechanism 14.

[0041] Optimally:

[0042] The automatic screw driving mechanism 12 is powered by a servo motor.

[0043] An electric screwdriver 3 is provided on the frame 6. The electric screwdriver 3 is equipped with an electric screwdriver control box 2 and is fixed on the vertical arm mechanism 8. The electric screwdriver control box 2 is signal-connected to the control electric box 9, and the control electric box 9 is signal-connected to the vertical arm mechanism 8. That is, the electric screwdriver 3 establishes a signal connection with the control electric box 9 through the electric screwdriver control box 2. In special cases, the operator manipulates the vertical arm mechanism 8 through the electric screwdriver control box 2 to make the electric screwdriver 3 act for emergency or supplementary operations. For example, when the screwing depth of the screw is abnormal, the control electric box 9 triggers an audible and visual alarm and pauses the process. At this time, the electric screwdriver 3 can be used for supplementary operations.

[0044] In another embodiment, the electric screwdriver 3 is detachably connected to the vertical arm mechanism 8, and the operator can remove the electric screwdriver 3 for more flexible operation. An electric screwdriver placement rack 4 for placing the electric screwdriver 3 can be provided on the frame 6.

[0045] The semi-automatic wire harness installation mechanism 14 includes a pneumatic flipping arm and an angle positioning module. That is, the pneumatic flipping arm generally adopts a mechanical structure driven by a cylinder, and the angle positioning module can adopt common methods such as the cooperation of screws and arc-shaped grooves, so that the wire harness can be flipped by a set angle, and the pneumatic flipping arm is configured with a sensor to detect whether the wire harness flipping is in place. The configured sensor is signal-connected to the control electric box 9, and the control electric box 9 is signal-connected to the cylinder of the pneumatic flipping arm. After flipping in place, the cylinder automatically ends the action, thus enabling automatic flipping of the product.

[0046] The control logic of the present invention is:

[0047] The control electric box 9 is built-in with a PLC module. After receiving the sensor signal, it executes in the following order: start signal → detect the tooling load → lock the cylinder → execute the assembly action → result feedback → release the cylinder.

[0048] The working mode of the present invention is:

[0049] Step 1 (operation at the first station):

[0050] After manually placing the ball head screw and the product, the start button 5 is triggered. The product presence detection sensor 11 detects the product in place, the product locking cylinder 10 is started, the first support tooling 611 fixes the product, the automatic screw screwing mechanism 12 executes screwing and detects the depth. After reaching the position, the product locking cylinder 10 is unlocked, and the semi-finished product is taken out.

[0051] Step 2 (operation at the second station):

[0052] After manually placing the semi-finished product on the second support tooling 621, the start button 5 is triggered. The product presence detection sensor 11 performs a secondary detection. The semi-automatic wire harness installation mechanism 14 automatically flips and presses the wire harness head. The product locking cylinder 10 is unlocked, and the finished product is taken out.

[0053] The screw assembly and wire harness installation processes of the present invention avoid process interference; and integrate multi-level detections such as product placement and screw depth, with high integration and relatively reliable products.

[0054] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
