Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp assembly technology, specifically to a pressing and nailing assembly for vehicle lamp assembly. Background Technology

[0002] In the production process of automotive lights, a very important step is to use an automotive light adhesive bonding device to perform adhesive bonding operations. Specifically, this mainly involves the connection between the light headlight cover and the light headlight. First, adhesive is applied to the light headlight, and then extrusion pressure is used to bond and fix the light headlight cover to the light headlight, thereby achieving a sealing effect.

[0003] In existing technologies, the pressing and assembly of automotive lights mostly relies on manual operation using hand-held pneumatic pressing tools or fixed-track pressing equipment (such as single-axis cylinder-driven pressing devices). After the headlight is positioned manually, the equipment is started to complete the pressing action in a single direction. When operating manually, the pressing force depends entirely on the operator's feel and experience, which is prone to uneven pressing force due to fluctuations in physical strength and lack of concentration (such as excessive pressure in some positions causing deformation of the headlight housing, and insufficient pressure in some positions causing loose assembly). The deviation rate is high, which directly affects the product qualification rate. On the other hand, fixed-track pressing equipment can only move along a single trajectory and cannot adapt to the pressing requirements of different angles and positions of the headlight. The headlight placement must be adjusted multiple times to complete the entire pressing process, which makes the operation cumbersome and time-consuming. Moreover, the equipment lacks precise force control components, and the pressing force is uncontrollable, which further reduces production efficiency and makes it difficult to meet the requirements of efficiency and quality consistency for large-scale production.

[0004] In light of this, we have launched a pressing and nailing assembly for vehicle lights to solve the problems of cumbersome operation, long time consumption, and reduced product qualification rate caused by manual pressing of vehicle lights and pressing of vehicle lights with fixed track pressing equipment.

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.

[0033] 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.

[0034] Example:

[0035] Please see Figure 1-9 This utility model provides a technical solution: a pressing and nailing assembly for vehicle headlight assembly, comprising: wherein, bracket 1 serves as the basic support structure of the entire assembly, and its core function is to be stably installed on the required processing table, providing a solid bearing foundation for all components above; the top plate 2 welded to the top of bracket 1 mainly serves to provide a platform for the fixed installation of a six-axis vertical multi-joint industrial robot 3; the welding connection ensures the firmness of the connection between the top plate 2 and bracket 1, and can effectively withstand various forces generated during robot operation.

[0036] The six-axis vertical multi-joint industrial robot 3 is installed on the top of the top plate 2. It is the core of the entire assembly. With its flexible six-axis movement characteristics, it can achieve multi-directional and multi-angle movement adjustment, which can meet the pressing requirements of different positions of the car headlights. At the same time, it can also move the car headlights that need to be pressed to the designated position. The fast plate connecting plate 5 at one end of the six-axis vertical multi-joint industrial robot 3 is a key component for connecting the fixing plate 4. It can quickly and accurately connect the fixing plate 4 to the six-axis vertical multi-joint industrial robot 3, which is convenient for later disassembly and replacement. The pressing air control box 6 on the top of the six-axis vertical multi-joint industrial robot 3 is the control center for driving the operation of the six-axis vertical multi-joint industrial robot 3.

[0037] The fixing plate 4 is bolted to the fast plate connecting plate 5. This connection method ensures the stability of the fixing plate 4 and facilitates position adjustment and maintenance. Multiple sets of support rods 9 are horizontally arranged on the other side of the fixing plate 4. They are mainly used to place the headlights to be pressed and assembled, providing stable support and positioning for the headlights. The pressing mechanism on the side of each set of support rods 9 is the execution component for pressing the headlights. Through the extension and retraction of the cylinder 10, it drives the claw 12 to move on the positioning frame 15 at the bottom of the support rod 9. Finally, the pressing claw 13 on the surface of the claw 12 performs a precise and stable pressing operation on the assembled headlights, ensuring that all parts of the headlights are tightly joined.

[0038] Specifically, regarding the pressing mechanism, the support plate 14, which is fixedly connected to the bottom of the support rod 9, mainly supports the cylinder 10, providing a stable mounting base for the cylinder 10. The positioning frame 15 is rotatably connected to the surface of the support plate 14, and the two are connected by a positioning pin 16. This allows the positioning frame 15 to rotate around the positioning pin 16 at a certain angle, facilitating position adjustment according to the shape of the headlight and pressing requirements. The concave frame 11 connected to the output end of the cylinder 10 transmits power, transferring the driving force of the cylinder 10 to the card. The claw 12 is hinged at the bottom inside the concave frame 11. This hinge structure gives the claw 12 a certain degree of freedom of movement. Combined with its sliding contact inside the positioning frame 15, it can better adapt to the trajectory of the pressing action. The two sets of connecting pins 18 and the sliding wheels 19 on the surface of the claw 12 cooperate with the guide holes 17 opened on the surface of the positioning frame 15. The sliding wheels 19 slide in the guide holes 17, providing precise guidance for the movement of the claw 12 and ensuring the accuracy of the pressing position of the pressing claw 13.

[0039] The support frames 7, which are connected at equal intervals on the surface of the fixing plate 4, further assist in supporting the placed vehicle lights. Together with the support rod 9, they improve the stability of the vehicle lights and prevent them from shaking during the pressing process. The rubber pads 8 on the surface of each set of support frames 7 have a protective function and can effectively prevent the vehicle lights from being scratched or damaged due to direct contact with the support frames 7, thus protecting the integrity of the vehicle lights surface.

[0040] The placement part 20 on the surface of the support rod 9 is a placement structure specially designed for the lamp pressing process. Its shape matches the corresponding part of the lamp, which can accurately position the lamp and ensure that the pressing operation is performed in the correct position.

[0041] The bracket 1 is set in four groups, which can evenly distribute the weight of the entire component and enhance the stability of the overall structure. The base plate 23 at the bottom of the four brackets 1 is welded to increase the contact area between the bracket 1 and the processing table, further improving the stability of the bracket installation and preventing the component from tipping over during operation. The reinforcing rib 22 between the base plate 23 and the bracket 1 is welded to effectively enhance the strength of the connection between the bracket 1 and the base plate 23 and resist the shear force between them. The reinforcing rod 24 between each bracket group 1 is welded to connect the four brackets 1 into an integral frame, improving the rigidity and deformation resistance of the entire bracket structure.

[0042] The equally spaced screw holes 21 on the surface of the top plate 2 provide connection points for the installation of the six-axis vertical multi-joint industrial robot 3. The six-axis vertical multi-joint industrial robot 3 is firmly fixed to the top plate 2 by bolts passing through the screw holes 21, ensuring the stability of the six-axis vertical multi-joint industrial robot 3 during operation.

[0043] The electrically operated valve assembly 28 (model SY5 series) connected inside the pressure control box 6 is a key component for controlling the movement of the six-axis vertical multi-joint industrial robot 3. By receiving control signals, it controls the opening and closing of the air path and the flow rate, thereby precisely controlling the movement trajectory and sequence of the six-axis vertical multi-joint industrial robot 3. The pressure gauge 29 (model SMC pressure gauge ISE30) located on the side of the electrically operated valve assembly 28 inside the pressure control box 6 is used to monitor the pressure situation inside the pressure control box 6 in real time. Operators can use the pressure gauge 29 to promptly understand the situation. Check if the air pressure is within the normal operating range to ensure the normal operation of the pressing mechanism. The waterproof connector 26 on the side (model can be PG29 or PG25) is used to connect the external air source and control circuit, and can play a good waterproof role to prevent moisture from entering the air control box and affecting the normal operation of electrical components. The sealing cover 25 (the cover 25 is a 3mm transparent acrylic plate) connected to the top of the pressing air control box 6 by bolts can seal and protect the components inside the pressing air control box 6, prevent dust, debris and other objects from entering, and also play a certain waterproof role.

[0044] The through hole 27 on the side of the pressurized air control box 6 is used for the waterproof connector 26 to pass through, providing a channel for the installation of the waterproof connector 26, ensuring that the waterproof connector 26 can be installed smoothly and perform its connection and waterproof functions.

[0045] The threaded hole 30 on the surface of the fast plate connecting plate 5 is used to fix the fixing plate 4 to the fast plate connecting plate 5 by means of a screw. The threaded connection method can ensure the firmness of the installation of the fixing plate 4, and at the same time facilitates disassembly and replacement as needed.

[0046] Specifically, during use, the four sets of brackets 1 are fixed to the processing table by the bottom plate 23. The reinforcing rods 24 between the brackets 1 and the reinforcing ribs 22 between the bottom plate 23 and the brackets 1 further enhance the stability of the overall structure, providing a solid foundation for the operation of the entire component.

[0047] The six-axis vertical multi-joint industrial robot 3, mounted on the top plate 2, is the core driving component of the entire assembly (the model of the six-axis vertical multi-joint industrial robot 3 is GP110_ASM_3). The screw holes 21 on the surface of the top plate 2 ensure the firmness of the installation of the six-axis vertical multi-joint industrial robot 3. The pressure control box 6 provides driving power for the six-axis vertical multi-joint industrial robot 3. The internal electric valve group 28 is used to precisely control the movement of the six-axis vertical multi-joint industrial robot 3. The pressure gauge 29 can monitor the pressure in real time, making it easy for operators to understand the operating status of the equipment. The waterproof connector 26 connects to the external wiring through the through hole 27, ensuring the safety and sealing of the circuit connection. The cover plate 25 protects the internal components of the pressure control box 6.

[0048] The fast plate connecting plate 5 at one end of the industrial robot 3 is bolted to the fixing plate 4 through the threaded hole 30, which realizes the stable installation of the fixing plate 4. The support frame 7 on the surface of the fixing plate 4 is used to place the vehicle light. The rubber pad 8 on the surface of the support frame 7 can effectively prevent the vehicle light from being worn during placement.

[0049] When the headlight pressing operation is performed, the headlight is placed on the placement part 20 of the support rod 9 and the support frame 7. Subsequently, the support plate 14 at the bottom of the support rod 9 provides stable support for the cylinder 10, and the pressing mechanism starts to work. The support plate 14 at the bottom of the support rod 9 provides stable support for the cylinder 10. The positioning frame 15 is rotatably connected to the surface of the support plate 14 through the positioning pin 16, and the angle can be adjusted according to the actual pressing requirements. After the output end of the cylinder 10 is started, its output end drives the concave frame 11 to move (i.e., move closer to the surface of the cylinder 10). Since the bottom of the pawl 12 is hinged inside the concave frame 11, the movement of the concave frame 11 drives the pawl 12 to slide inside the positioning frame 15. At this time, the two sets of connecting pins 18 on the surface of the pawl 12 move with the pawl 12, and the sliding wheel 19 on the connecting pin 18 rolls in the guide hole 17 of the positioning frame 15. The guide hole 17 restricts the sliding wheel 19 to move along the track. The positioning bracket 15 can rotate slightly around the positioning pin 16 to adapt to the angle changes of the pawl 12 during movement, ensuring smooth movement. Two guide holes 17 are provided, one straight and one bent, to control the rotation of the pawl 12. The straight section of the guide hole 17 guides the pawl 12 smoothly and accurately towards the headlight to be pressed. The bent section of the guide hole 17 constrains the trajectory of the sliding wheel 19 when the pawl 12 approaches the headlight, controlling the slight rotation of the pawl 12. As the pawl 12 continues to move, its surface pressing claw 13 gradually approaches the headlight. When it reaches the preset pressing position, the pressing claw 13 contacts the headlight structure to be pressed. The cylinder 10 continuously outputs a retraction force, which is transmitted through the concave bracket 11 and the pawl 12 to the pressing claw 13, performing the pressing operation on the headlight (e.g., ...). Figure 4 (As shown in the state) During this process, the sliding wheel 19 rolls to the corresponding position in the guide hole 17. Relying on the shape and length of the guide hole 17, the direction and magnitude of the pressure applied by the pressing claw 13 are kept stable, which meets the requirements of the vehicle lamp assembly pressing process, and achieves precise and stable pressing, thereby completing the pressing assembly process of the vehicle lamp for subsequent nailing processing.
