Technical Field

[0001] This invention relates to the field of automotive parts assembly technology, and in particular to a semi-automatic inspection and assembly machine for automotive headlight components. Background Technology

[0002] Currently, the assembly of automotive headlight components largely relies on manual operation, which presents the following problems: 1) Manual assembly is inefficient and costly; 2) Key parameters such as screw tightening depth and wiring harness installation angle are difficult to control precisely, resulting in low product qualification rates; 3) Manual inspection is prone to omissions or misjudgments, leading to low work efficiency. Meanwhile, some existing automated equipment also suffers from complex structures, making it difficult to adapt to the needs of multi-process collaborative operations. Summary of the Invention

[0033] 14. Semi-automatic wiring harness installation mechanism. Detailed Implementation

[0034] See the example. Figures 1 to 3 As shown: A semi-automatic testing and assembly machine for automotive headlight components, including a frame 6. The frame 6 has casters 7 at the bottom, a pneumatic-electric quick-connect fitting 13 in the middle, and integrates a fluorescent lamp 1 and a vertical arm mechanism 8 at the top. The vertical arm mechanism is used to adjust the spatial position of the electric screwdriver 3 to maintain a certain verticality during operation, and the pneumatic-electric quick-connect fitting 13 is used for quick connection of the air circuit and the electrical circuit.

[0035] To elaborate further:

[0036] The frame 6 is equipped with two workstations, namely located at... Figure 1 The first workstation 61 on the left and the second workstation 62 on the right are shown.

[0037] The first workstation 61 is equipped with a first support fixture 611 for clamping the product and an automatic screw-in mechanism 12 for screwing in the screw. The automatic screw-in mechanism 12 is equipped with a screw presence detection sensor and a screw insertion depth sensor.

[0038] The second workstation 62 is equipped with a second support fixture 621 for clamping the product and a semi-automatic wire harness installation mechanism 14 for pressing in the wire harness.

[0039] Both the first support fixture 611 and the second support fixture 621 are matched with a product locking cylinder 10, which is equipped with a product presence / absence detection sensor 11. This product presence / absence detection sensor 11 can be a photoelectric sensor and can be installed at the bottom of the positioning groove or other part of the corresponding fixture. That is, after the product presence / absence detection sensor 11 detects that the product is in place, it sends an action command to the product locking cylinder 10. After the product locking cylinder 10 actuates, the first support fixture 611 and the second support fixture 621 clamp the corresponding product.

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

[0041] Optimized:

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

[0043] The frame 6 is equipped with an electric screwdriver 3, which has an electric screwdriver control box 2 and is fixed to the vertical arm mechanism 8. The electric screwdriver control box 2 is connected to the control box 9, which in turn is connected to the vertical arm mechanism 8. That is, the electric screwdriver 3 establishes a signal connection with the control box 9 through the electric screwdriver control box 2. In special circumstances, the operator can control the vertical arm mechanism 8 through the electric screwdriver control box 2 to activate the electric screwdriver 3 for emergency or supplementary work. For example, when the screw is screwed into the wrong depth, the control box 9 triggers an audible and visual alarm and suspends the operation. At this time, the electric screwdriver 3 can be used for supplementary work.

[0044] In another embodiment, the electric screwdriver 3 is detachably connected to the vertical arm mechanism 8, allowing the operator to remove the electric screwdriver 3 for more flexible operation. The frame 6 may be equipped with an electric screwdriver holder 4 for placing the electric screwdriver 3.

[0045] The semi-automatic wiring harness installation mechanism 14 includes a pneumatic flipping arm and an angle positioning module. Specifically, the pneumatic flipping arm typically employs a mechanical structure driven by a cylinder, while the angle positioning module utilizes common methods such as screws and arc-shaped grooves to allow the wiring harness to be flipped to a set angle. The pneumatic flipping arm is equipped with a sensor to detect whether the wiring harness has been flipped correctly. The sensor signal is connected to the control box 9, and the control box 9's signal is connected to the cylinder of the pneumatic flipping arm. Once the wiring harness is flipped correctly, the cylinder automatically stops its action, thus enabling automatic product flipping.

[0046] The control logic of this invention is:

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

[0048] The working principle of this invention is as follows:

[0049] Step 1 (Operation at the first workstation):

[0050] After manually placing the ball head screw and the product, the start button 5 is triggered. The product detection sensor 11 detects that the product is in place, the product locking cylinder 10 is activated, the first support fixture 611 fixes the product, the automatic screw-in mechanism 12 performs tightening and detects the depth, and after the product is in place, the product locking cylinder 10 is unlocked and the semi-finished product is taken out.

[0051] Step Two (Operation at the Second Workstation):

[0052] After the semi-finished product is manually placed onto the second support fixture 621, the start button 5 is triggered. The product has a secondary detection sensor 11, and the semi-automatic wiring harness installation mechanism 14 automatically flips and presses in the wiring harness head. The product locking cylinder 10 is then unlocked, and the finished product is removed.

[0053] This invention separates the screw assembly and wire harness installation processes, avoiding process interference; and integrates multi-level detection such as product arrival and screw depth, resulting in high integration and more reliable products.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
