Description

Technical Field

[0001] This utility model relates to the field of automotive lamp screw technology, specifically to an automatic screw-locking device for automotive lamps. Background Technology

[0002] Car lights not only provide illumination but also transmit information. When a car needs to turn or brake, the rear combination lights can alert following vehicles. Therefore, car lights are an important component of a car. However, as people's living standards improve, their demands for goods also increase, and this is also true for cars. In order to better meet customer needs, car lights need to undergo many processes before installation to meet requirements. During the installation process, due to the special structure of car lights, the installation of screws is very difficult.

[0003] In the current technology, the assembly of vehicle headlight screws is mostly carried out by manual hand-held electric screwdrivers or a single set of automated screw-locking mechanisms. When operating manually, the operator holds the electric screwdriver and tightens the screw on the headlight, relying on experience to control the tightening force and angle. A single set of automated screw-locking mechanisms uses a fixed track or a single-axis robotic arm to move the screw-locking components, which can only perform screw-locking operations on screws in specific areas of the headlight.

[0004] However, when manually tightening screws with a handheld electric screwdriver, the operator's physical strength, visual fatigue, and differences in operating experience make it difficult to ensure that the tightening force and angle of each screw are consistent. This can easily lead to quality problems such as screws being too loose, causing unstable connections of the headlight components, or screws being too tight, causing stripping or damage to the headlight housing. In addition, manual operation is inefficient and cannot meet the needs of large-scale mass production. A single automated screw-locking mechanism, due to its fixed motion trajectory or limited degree of freedom of the robotic arm, cannot reach screws in the complex narrow spaces or hidden locations on the headlight. It can only complete the screw-locking work in some areas. When faced with the diverse screw layouts of different headlight models, it is necessary to frequently adjust equipment parameters or change tooling. It has poor adaptability, cannot flexibly cope with complex processing scenarios, and cannot completely get rid of the dependence on manual assistance.

[0005] In light of this, we have launched an automatic screw-locking device for automotive lights. Utility Model Content

[0006] The purpose of this invention is to provide an automatic screw-locking device for vehicle lights, so as to solve the problems mentioned in the background art.

[0011] Preferably, the side beam is detachably connected to a hanging ring, and the inside of the hanging ring is provided with a winding rope. The bottom of the winding rope is connected to a screw-locking machine B, and the output end of the screw-locking machine B is provided with a screw cutter head B for tightening screws. The cooperation between the hanging ring and the winding rope can flexibly adjust the position of the screw-locking machine B so that it can cooperate with the main screw-locking mechanism to handle screw-locking work at different positions of the vehicle headlight. The disassembly design also facilitates maintenance and replacement.

[0012] Preferably, a track C is provided at the center of the surface of the processing table, a slider C is slidably attached to the surface of the track C, and a processing frame is connected to the top of the slider C.

The sliders D are connected to the bottom of the processing frame, and the side of the processing frame is provided with a secondary drag chain for assisting in driving the movement of the processing frame. The rails and sliders on both sides further enhance the stability of the processing frame when it moves. The secondary drag chain works in conjunction with the main drag chain to make the movement of the processing frame smoother and more efficient.

[0014] Preferably, the bottom frame is provided with a protective plate A on its side for protection, and the bottom of the bottom frame is provided with casters; the protective plate A can effectively block external debris from entering the equipment, and the casters facilitate the movement and fixation of the equipment, thus taking into account both the safety and ease of movement of the equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) In the screw tightening mechanism, the screw tightening machine A provides a stable driving force to drive the screw cutter head A to rotate. The end is designed with a matching structure according to the screw model and specifications. With the precise movement of the six-axis collaborative robot arm, the screw is tightened accurately, which improves the assembly accuracy of the car headlight screws, reduces product quality problems caused by improper screw tightening, and reduces manual operation. At the same time, the screw tightening machine B on the side beam is suspended on the hanging ring by the winding rope. The winding rope has good flexibility and strength. The operator can move the screw tightening machine B to various corners of the equipment as needed. For screws in narrow spaces or special positions that are difficult for the six-axis collaborative robot arm to reach, the tightening operation can be effectively performed. This combination of dual screw tightening methods enables the equipment to adapt to various complex processing scenarios. Whether it is simple batch production or complex personalized processing, it can handle it with ease, which improves the equipment's adaptability to different processing scenarios.

[0020] (2) The processing rack can move quickly and accurately to the processing position through the cooperation of the main drag chain, the auxiliary drag chain, the track and the slider, reducing the workpiece positioning time;

[0021] (3) All six joints of the six-axis collaborative robotic arm can rotate flexibly, enabling its end to reach any position and adjust its posture in three-dimensional space, which drives the screw-tightening mechanism to easily meet the screw-tightening needs of different positions and angles of the car lights.

[0031] 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.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] Please see Figure 1-8 This utility model provides a technical solution: an automatic screw-locking device for vehicle lights, comprising: a basic support part of the device consisting of a base frame 1 and side beams 4. The base frame 1 is placed on the ground, providing a stable load-bearing foundation for the entire device and ensuring that the processing accuracy is not affected by factors such as vibration during operation; the side beams 4 are installed on the top of the base frame 1, which not only connect and support other components, but also build a framework for the overall structure of the device. The processing table 10 on one side of the top of the base frame 1 is the main working area for processing vehicle lights. The placement rack 11 on one side of its top is used to orderly place vehicle lights to be processed or already processed, which is convenient for operators to pick up and put down, and also avoids damage to the vehicle lights during turnover.

[0034] The six-axis collaborative robotic arm 13 located inside the base frame 1 on one side of the processing table 10 is the core component for the automated operation of the equipment. It has multi-degree-of-freedom motion capability, and its end can be flexibly rotated to different positions. It can accurately align with the headlight screw holes on the processing table. The detachable mounting plate 18 on one side of the six-axis collaborative robotic arm 13 provides a mounting carrier for the wire tightening mechanism, and the detachable design facilitates the maintenance and replacement of the wire tightening mechanism.

[0035] The screw-tightening mechanism installed on the side of the mounting plate 18 is crucial for completing the screw tightening operation. Positioning blocks 30 connected to the upper and lower sides of the mounting plate 18 position and limit the components of the screw-tightening mechanism. The slide rail A29 on the side of the mounting plate 18 cooperates with the slider A28, allowing the slider A28 to slide smoothly on the surface of the slide rail A29. The L-shaped seat 27 on one side of the slider A28 supports the screw-locking machine A19, ensuring its stability during operation. A set of cylinders on top of the positioning blocks 30 provides power for the sliding of the L-shaped seat 27, driving the screw-locking machine A19 and related components to move up and down, adjusting the working height. The screw-locking machine A19 serves as the power source, and its output end is connected to the screw cutter head A32. Driven by the rotation, the slide rail A29 is located on the bottom of the slider A28, and the slider B34 is connected to a limit sleeve 33 on one side. The screw cutter head A32 extends into the limit sleeve 33. The limit sleeve 33 guides and stabilizes the rotation of the screw cutter head A32, preventing it from shaking during high-speed rotation. The end 35 is connected to the bottom of the limit sleeve 33 and passes through another set of positioning blocks 30. It has a matching groove or protrusion structure designed according to the model and specifications of the screw to be tightened, ensuring a tight fit with the screw. During operation, the screw tightening mechanism uses the stable power output of the screw locking machine A19, the rotation transmission of the screw cutter head A32, and the precise fit between the end 35 and the screw to achieve precise tightening of the screw, completing the assembly or fastening of the vehicle light.

[0036] The smooth rod 38 between the L-shaped seat 27 and the limiting sleeve 33 serves as a limit and guide, ensuring the stability of the L-shaped seat 27 and the limiting sleeve 33 during relative movement. The spring 31 fitted on its surface can buffer the movement of the components and reduce the impact on the equipment. The control box 17 on the surface of the six-axis collaborative robotic arm 13 is used to drive and control the various actions of the six-axis collaborative robotic arm 13 and the wire twisting mechanism, realizing precise control of automated operation.

[0037] The side beam 4 has a detachable hanging ring 37 on its surface. The bottom of the internal winding rope 16 is connected to a wire locking machine B14. The screw cutter head B15 at the output end of the wire locking machine B14 can be used as an auxiliary wire twisting device to improve processing efficiency while the main wire twisting mechanism is working, or to address positions that the wire twisting device cannot process.

[0038] The track C22, located in the center of the surface of the processing table 10, cooperates with the slider C26, allowing the processing frame 12 connected to the top of the slider C26 to slide on the track C22. The main drag chain 25, located on the side of the slider C26 on the surface of the processing table 10, provides the main driving force for the movement of the processing frame 12, driving the processing frame 12 to adjust its position to adapt to the processing requirements of different specifications of vehicle lights. The handles 20 on both sides of the top of the processing frame 12 and the placement frame 11 make it convenient for the operator to manually adjust the position of the processing frame 12 and the placement frame 11 when needed. The track D23, located on both sides of the track C22 on the surface of the processing table 10, cooperates with the slider D24. The slider D24 is connected to the bottom of the processing frame 12, further enhancing the stability of the processing frame 12 when moving. The auxiliary drag chain 21 on the side of the processing frame 12 assists in driving the movement of the processing frame 12, working in coordination with the main drag chain 25 to ensure smooth movement of the processing frame 12.

[0039] The protective plate A3 on the side of the bottom frame 1 serves a protective function, preventing external factors from interfering with the operation of the internal components of the equipment, and also preventing injury to the operators during equipment operation; the casters 2 at the bottom of the bottom frame 1 facilitate the movement and fixation of the equipment, allowing the equipment to be flexibly adjusted in position according to production needs; the protective plate B5 on the side of the side beam 4 and the protective top plate 6 together constitute the protective system of the equipment, protecting the internal components of the equipment from the influence of dust, debris, etc., while ensuring the safety of the working environment.

[0040] The control button 8 at the front end of the side beam 4 allows operators to manually control the equipment and set parameters. The display screen 9 above the control button 8 can display the equipment's operating status, processing parameters, and other information in real time, making it convenient for operators to monitor the equipment's operation. The alarm light 7 on the top of the protective top plate 6 will sound an alarm when the equipment malfunctions or encounters abnormal conditions, reminding operators to handle the situation promptly. The support 36 at the bottom of the six-axis collaborative robotic arm 13, located on the surface of the base frame 1, enhances the stability of the robotic arm's installation and ensures that it will not shift during high-speed operation.

[0041] The hardware components of this utility model are as follows: main electrical components, 1 main power cam switch, 2 DC12V camera power outputs, 1 DC24V steady-state DC output power supply 5A, 1 set of PLC main control system (Siemens), robotic arm (i.e., six-axis collaborative robotic arm 13) Yaskawa brand (GP12) capable of bearing a load of 12 kg, nail feeding system: Dawu screw machine, 2 sets of Qilisuo electric locks and controllers: KD-BN519L+SKP-BC32 (1 set of automatic lock, 1 set of manual lock replacement), 10-inch Weintek touch screen MT8106IE, 21-inch all-in-one machine (INTEL(R) Core(TM) i5-337U@1.80GHZ 4.0G installed memory);

[0042] The pneumatic circuit includes an 8-way 2-position 5-way solenoid valve with single electric control output, a pneumatic circuit triplet, a pneumatic circuit pressure switch, a pneumatic circuit switch that can manually cut off the air supply, a pressure gauge, a working pressure of 0.6MPa, a Veen heavy-duty lower shell H24B-SHE-2B-M32, a Veen frame HF24B-NUA3, a Veen pneumatic module HMP-003, a Veen pneumatic needle PCM-4.0, a Veen plug-in HMD-012-MC, a Veen cooling needle CDSM-1.5, and black ∮12, ∮8, ∮6, and ∮4 tubing. The fixture uses female connectors, and the equipment uses male connectors. The selection signal and anti-fool signal are connected to the socket. There should be 4 sets of pneumatic circuits and 6 anti-fool signals on the table.

[0043] In the control panel section, ABORTCYCLE: interrupt loop, PRODUCTOK: product latching passed (green light), PRODUCTNOK: product latching failed (red light), TESTINPROCESS: latching in progress (yellow light), DEFECTACK: reset, CONTINUE: continue testing, STOP: emergency stop;

[0044] For the electrical component selection of the control system, the PLC is Siemens. The PLC at the workstation needs to be converted using a serial-to-network module for communication. A spare PLC communication port must be reserved. If not, an expansion port for the PLC needs to be added. Electrical control components are Schneider Electric, Omron, Honeywell, or equivalent brands. The grating is Yangming. The sensor is Keyence or Omron. Pneumatic components include SMC cylinders and seals, THK guide rails and bearings, and FESTO or SMC air hoses and connectors, etc.

[0045] The above can be flexibly selected according to actual usage, and will not be elaborated here.

[0046] Specifically, during use, the operator can push the equipment through the casters 2 at the bottom of the base frame 1. After the equipment is moved to a suitable working area, the braking device of the casters 2 is locked to fix the equipment firmly on the ground and prevent displacement during the work process. Then, the operator places the car light to be processed on the placement rack 11 on the top side of the processing table 10. The structure of the placement rack 11 is adapted to the shape of the car light and can provide good support and positioning for the car light, preventing the car light from shaking or shifting during subsequent processing.

[0047] A track C22 is centrally located on the surface of the processing table 10. Both ends of the track C22 are securely mounted on the processing table 10 using fasteners. A slider C26 is engaged with the track C22, allowing it to slide smoothly along the length of the track. The top of the slider C26 is fixedly connected to the bottom of the processing frame 12 using bolts or other connectors. One end of the main drag chain 25 is connected to the side of the slider C26, and the other end is fixed to the surface of the processing table 10. When the main drag chain 25 starts, it generates traction, causing the slider C26 to move on the track C22, thereby causing the processing frame 12 to move synchronously. Simultaneously, tracks D23 are provided on both sides of the track C22. The tracks D23 are parallel to the track C22 and are also mounted on the processing table 10 using fasteners. A slider D24 is engaged with the track D23. The top of the processing rack 12 is also connected to the bottom of the processing rack 12. When the processing rack 12 moves, the slider D24 will slide on the track D23 along with the processing rack 12, playing a role in auxiliary support and guidance, ensuring the smooth movement of the processing rack 12. One end of the auxiliary drag chain 21 is connected to the side of the processing rack 12, and the other end is fixed on the processing table 10. The auxiliary drag chain 21 works in conjunction with the main drag chain 25 to further enhance the driving ability of the processing rack 12, so that the processing rack 12 can accurately reach the processing position corresponding to the car light to be processed, so as to meet the processing requirements of different models and specifications of car lights. In addition, the top sides of the processing rack 12 and the placement rack 11 are respectively connected to handles 20. The operator can manually adjust the position of the processing rack 12 and the placement rack 11 when necessary through the handles 20, improving the flexibility of operation.

[0048] The bottom of the six-axis collaborative robotic arm 13 is fixed to the surface of the base frame 1 by a support 36. The support 36 provides a solid support foundation for the six-axis collaborative robotic arm 13, ensuring that it will not shake during movement. The control box 17 is installed on the surface of the six-axis collaborative robotic arm 13. It contains various control circuits and chips, which can receive and process external commands and send action signals to the six-axis collaborative robotic arm 13. Driven by the control box 17, each joint of the six-axis collaborative robotic arm 13 can rotate flexibly, allowing its end to rotate to different spatial positions. The mounting plate 18 is installed at the end of the six-axis collaborative robotic arm 13 by detachable connectors such as bolts. When it is necessary to replace or repair the screw tightening mechanism, the mounting plate 18 can be easily removed. The six-axis collaborative robotic arm 13 drives the mounting plate 18 and the screw tightening mechanism installed on the mounting plate 18 to move. Through precise position control, the end 35 of the screw tightening mechanism is accurately aligned with the position of the screw to be tightened.

[0049] In the wire tightening mechanism, positioning blocks 30 are connected to the upper and lower sides of the mounting plate 18, respectively. The positioning blocks 30 are fixed to the mounting plate 18 by welding or bolting, serving as limiters and supports. A slide rail A29 is also connected to the side of the mounting plate 18. The length of the slide rail A29 is aligned with the height of the mounting plate 18. Slider A28 and slider B34 are respectively engaged on the slide rail A29, with slider A28 positioned above slider B34. Both can slide freely along the slide rail A29. One side of the L-shaped seat 27 is fixedly connected to slider A28. (Wire tightening machine) A19 is bolted to the surface of L-shaped seat 27. A cylinder is mounted on the top of a set of positioning blocks 30. The piston rod end of the cylinder is connected to L-shaped seat 27. When the cylinder is activated, the piston rod extends or retracts, causing L-shaped seat 27 and slider A28 to move up and down along slide rail A29, thereby adjusting the height position of wire locking machine A19. The output end of wire locking machine A19 is connected to lead screw cutter head A32. When wire locking machine A19 is activated, it outputs a stable rotational driving force, causing lead screw cutter head A32 to rotate at high speed. The lower end of lead screw cutter head A32 extends to the limit sleeve. Inside the 33, one side of the limiting sleeve 33 is fixedly connected to the slider B34, allowing the limiting sleeve 33 to slide on the slide rail A29 along with the slider B34. The end 35 is connected to the bottom of the limiting sleeve 33, and the lower end of the end 35 passes through another set of positioning blocks 30. The positioning blocks 30 guide and limit the movement of the end 35. A smooth rod 38 is provided between the L-shaped seat 27 and the limiting sleeve 33. The two ends of the smooth rod 38 are fixedly connected to the L-shaped seat 27 and the limiting sleeve 33, respectively. A spring 31 is sleeved on the surface of the smooth rod 38, and the two ends of the spring 31 abut against the L-shaped seat 27. When the L-shaped seat 27 moves downward, it will push the limit sleeve 33 downward through the light rod 38. The spring 31 will be compressed in this process, generating elastic force, which plays a buffering role and avoids rigid collision between the end 35 and the screw. The end 35 is designed with a matching groove or protrusion structure according to the model and specification of the screw to be tightened. When the end 35 contacts the screw, it can be tightly engaged with the screw under the rotation of the screw cutter head A32 to achieve precise screw tightening operation and complete the screw assembly or fastening operation of the vehicle light.

[0050] The surface of the side beam 4 is connected to a hanging ring 37 by detachable connectors such as bolts or hooks. The hanging ring 37 can be adjusted within a certain range on the surface of the side beam 4. One end of the winding rope 16 passes through the hanging ring 37 and can freely retract within the hanging ring 37. The bottom of the winding rope 16 is connected to the wire locking machine B14. The operator can adjust the height and horizontal position of the wire locking machine B14 by pulling the winding rope 16, so that the screw cutter head B15 at the output end of the wire locking machine B14 is aligned with the screw position that needs to be tightened. After the wire locking machine B14 is started, it will drive the screw cutter head B15 to rotate and tighten the screw at a specific position. As a supplement to the wire tightening mechanism, it can handle some screw positions that are difficult for the wire tightening mechanism driven by the six-axis collaborative robot arm 13 to reach, thus improving the processing flexibility of the equipment.

[0051] Control buttons 8 are installed at the front end of the side beam 4. Operators can send start, stop, parameter adjustment and other operation commands to the control box 17 by pressing different control buttons 8. A display screen 9 is installed above the control buttons 8, which can display the speed of the wire locking machine, the position of the processing frame, the movement status of the six-axis collaborative robotic arm, etc. It can also display the processing progress, fault information and other processing status, so that operators can monitor the operation of the equipment in real time. An alarm light 7 is installed on the top of the protective top plate 6. The alarm light 7 is connected to the fault detection circuit in the control box 17. When the equipment has an abnormal situation during operation, such as the sensor detecting that the screw is not tightened or the robotic arm moves abnormally, the control box 17 will send a signal to the alarm light 7, causing the alarm light 7 to flash and sound an alarm, so as to remind the operator to deal with it in time.

[0052] The side of the bottom frame 1 is bolted with a protective plate A3. The protective plate A3 is made of high-strength metal material and can isolate the six-axis collaborative robotic arm 13 and other components inside the bottom frame 1 from the outside, preventing operators from accidentally touching the internal moving parts during equipment operation. The side of the side beam 4 is equipped with a protective plate B5, which is also made of metal and can protect the internal structure of the side beam 4 and components such as the wire locking machine B14. The top of the side beam 4 is equipped with a protective top plate 6. The protective top plate 6 can not only prevent dust, debris and other objects from falling into the equipment, but also form a protective barrier above the equipment to prevent objects falling from above from causing damage to the equipment and operators.

[0053] The bottom of the six-axis collaborative robotic arm 13 is fixedly connected to the support 36 by high-strength connectors such as bolts. The bottom of the support 36 is firmly installed on the surface of the base frame 1 by welding or bolting. The structure of the support 36 is carefully designed to have sufficient strength and rigidity to bear the weight of the six-axis collaborative robotic arm 13 and the wire twisting mechanism. At the same time, it can effectively suppress vibration when the six-axis collaborative robotic arm 13 performs various complex actions, ensuring the stability and accuracy of the robotic arm when driving the wire twisting mechanism to move and work.
