Description

Technical Field

[0001] This application relates to the field of automotive manufacturing technology, and in particular to a transfer fuel injection system and a fuel injection workstation including the same. Background Technology

[0002] During the automated production line for parts such as side panels in automobile manufacturing, anti-splatter oil needs to be applied to the parts. Its purpose is to prevent spatter generated during welding from adhering to the surface of the parts. If spatter remains, it will negatively affect the appearance quality after subsequent painting or spraying, reduce the visual quality of the product, and increase the amount of rework. Therefore, applying anti-splatter oil is a critical process. After the oil is applied, two workers usually need to carefully remove the oiled parts and place them on a transfer rack. The parts are then transported to the installation station by the rack to ensure the continuity of the production process.

[0003] However, the current production process has many problems. The manual part removal process requires waiting for the oiling to finish, which greatly limits the production rhythm and results in extremely low overall efficiency, making it difficult to meet the needs of high-efficiency production. Furthermore, manual oiling relies on specialized personnel, making it difficult to control the amount and consistency of oil applied: excessive oiling leads to unnecessary waste and increases production costs; insufficient oiling results in significantly more spatter during welding, which in turn increases the workload of the grinding station and seriously affects production utilization. Utility Model Content

[0004] Therefore, the purpose of this invention is to overcome the shortcomings of existing automotive parts oiling processes, such as manual part handling and extremely low overall efficiency, as well as the difficulty in controlling the amount and consistency of oil used. This invention provides a transfer and spraying system and a spraying workstation comprising the system. This invention fully automates the handling, spraying, and transfer processes, completing the entire process through the coordinated work of various devices, thus improving production continuity and efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A transfer and spraying system includes a movable support that reciprocates along a first direction, a lifting support mounted on the movable support and reciprocating along a second direction, a part-picking device for picking up and placing parts on the lifting support, and a spraying device on the lifting support; it also includes a control system that connects the movable support, the lifting support, the part-picking device and the spraying device respectively.

[0007] This application can be installed in the area between the elevator and the parts conveyor of an automated production line for stamped parts. The control system is programmed to control the reciprocating motion of the moving support in this area. The lifting support is also controlled to move vertically up and down upon reaching the elevator position. A part-picking device on the lifting support automatically picks up and secures the part from the elevator. After picking up the part, it is moved to the spraying area via the moving support. The control system is programmed to control the spraying device to automatically spray anti-splatter oil. After spraying, the part is moved to the parts conveyor area via the moving support, and then transferred to the hanger of the parts conveyor via the lifting support and the part-picking device. This completes the handling, spraying, and transfer of automotive stamped parts, ultimately achieving automated conveying and spraying. This application can be precisely installed in a specific area between the elevator and the parts conveyor on an automated production line for stamped parts, without requiring large-scale modifications to the existing production line. It is well-suited for specific scenarios. The lifting bracket and the part-picking device can automatically pick up and fix the parts. After picking up the parts, the moving bracket can automatically move to the oil spraying area via the oil spraying device. After completion, the parts are automatically transferred to the hangers on the conveyor. The entire process of handling, oil spraying, and transfer is automated. The entire process is completed through the collaborative work of various devices, which improves the continuity and efficiency of production. Moreover, automated oil spraying can ensure the consistency and quality stability of the oil spraying for each part.

[0008] Furthermore, the movable support includes a base, a first guide rail disposed on the base, a movable seat disposed on the first guide rail, and a first drive device connecting the movable seat and causing it to reciprocate on the first guide rail; the lifting support includes a gantry frame disposed on the movable seat, a second guide rail disposed on the gantry frame, a lifting arm disposed on the second guide rail, and a second drive device connecting the lifting arm and causing it to reciprocate on the second guide rail; the axis of the first guide rail is parallel to the mounting surface, the axis of the second guide rail is perpendicular to the axis of the first guide rail, and the part-picking device and the oil spraying device are disposed on the lifting arm.

[0009] The mobile support of this application achieves stable horizontal reciprocating motion through the combination of a base, a first guide rail, a mobile seat, and a first drive device, providing a reliable foundation for overall movement; the lifting support adopts a structure of a gantry frame, a second guide rail, a lifting arm, and a second drive device, ensuring stable execution of lifting actions and improving the reliability of longitudinal movement; the axis of the first guide rail is parallel to the mounting surface (generally in the horizontal direction), and the axis of the second guide rail is perpendicular to the axis of the first guide rail (generally in the vertical direction), forming an orthogonal motion system, ensuring that the movement and lifting actions do not interfere with each other, and improving the accuracy of equipment operation.

[0010] Furthermore, the oil injection device includes a third guide rail disposed on the lifting arm, a mounting base disposed on the third guide rail, and a third drive device connected to the mounting base and reciprocating on the third guide rail; it also includes a fourth guide rail disposed on the mounting base, a nozzle module disposed on the fourth guide rail, and a fourth drive device connected to the nozzle module and reciprocating on the fourth guide rail; the axis of the third guide rail is parallel to the axis of the second guide rail, and the axis of the fourth guide rail is perpendicular to the axis of the third guide rail.

[0011] This application utilizes a third and fourth guide rail to form an orthogonal motion system. Combined with a third and fourth drive unit, it enables the nozzle module to reciprocate in two vertical directions, flexibly covering the injection area. The third and fourth drive units independently drive the mounting base and nozzle module, providing direct power transmission and precise control of movement in different directions, ensuring the stability and efficiency of the injection process. In this application, the third and fourth drive units can directly deliver reciprocating power to the telescopic cylinder.

[0012] Furthermore, the part-retrieving device includes a hanging bracket on the lifting arm for hanging parts, and a limiting bracket on the lifting arm for limiting the position of parts. Thus, by using the hanging bracket to hang the parts and the limiting bracket for positioning, this dual structure ensures that the parts are not easily detached during retrieval and subsequent movement, improving the stability of the retrieval process.

[0013] Furthermore, the hanging bracket includes two suspension brackets symmetrically arranged on the lifting arm, and a V-shaped limiting block at the end of each suspension bracket; the limiting bracket consists of two forks symmetrically arranged on the lifting arm, with the ends of the two forks flared outwards. In this way, the hanging bracket uses two symmetrical suspension brackets with V-shaped limiting blocks at the ends, which can stably hold the parts and adapt to parts of different sizes through the V-shaped structure, enhancing versatility; the limiting bracket consists of two symmetrical forks with flared ends, facilitating the smooth entry of parts into the limiting range between the two forks. This is suitable for stamped parts with longitudinal structures in the middle, such as automotive side panels, where there is a B-pillar crossbar in the middle. The symmetrical layout of the two forks can provide balanced limiting from both sides, ensuring accurate part positioning.

[0014] Furthermore, the base is also provided with a part fixing rocker arm for limiting and fixing the bottom of the part, and a first stop block provided on the gantry for limiting and fixing the side wall of the part.

[0015] Furthermore, the component fixing rocker arm includes a telescopic cylinder, a connecting arm rotatably connected to the output end of the telescopic cylinder at one end, and a second stop at the other end of the connecting arm; it also includes a pull rod that is fixedly connected to the fixed end of the telescopic cylinder at one end and rotatably connected to the connecting arm at the other end.

[0016] In this way, the bottom of the part is limited and fixed by the part fixing rocker arm on the base, and the side wall of the part is limited and fixed by the first stop on the gantry frame. The hanging frame and fork arm on the lifting arm form a multi-directional fixing system, which can stabilize the part from different dimensions and prevent it from shifting or shaking during handling, oiling and other processes, thus ensuring operational stability. On the other hand, the part fixing rocker arm has an adjustable range. This structural design makes the fixing action flexible and controllable, and can adapt to the fixing needs of parts of different specifications.

[0017] Furthermore, it also includes a positioning detector mounted on the base for detecting the position of the base, and a part detector mounted on the gantry for detecting the position of the part. The positioning detector ensures the safe movement of the moving support, and anti-collision blocks can be used at the end point of the first guide rail on the base to prevent the moving support from overtraveling and derailing; the part detector is used to detect whether there is a part at the picking position to prevent empty transport.

[0018] Furthermore, the first driving device includes a gear-driven motor mounted on the base, a rotating gear mounted at the output end of the gear-driven motor, and a gear transmission bar with its axis parallel to the axis of the first guide rail, wherein the rotating gear meshes with the gear transmission bar for transmission; the second driving device includes a lifting column drive motor fixed on the gantry frame, a threaded screw connected to the output end of the lifting column drive motor with its axis parallel to the axis of the second guide rail, and a lifting nut threadedly connected to the threaded screw, wherein the lifting arm is fixed on the lifting nut.

[0019] In this way, the first drive device uses a gear-driven motor to drive a rotating gear, which meshes with a gear transmission bar parallel to the axis of the first guide rail to achieve reciprocating motion of the moving seat on the first guide rail. The gear meshing transmission has the characteristics of precise transmission ratio and stable power transmission, ensuring that the moving seat moves accurately and efficiently. The second drive device drives a threaded screw to rotate through a lifting column drive motor. The lifting nut, which is threadedly connected to the threaded screw, reciprocates on the second guide rail. The threaded transmission has the advantages of high transmission accuracy and good self-locking, which can accurately control the lifting action of the lifting arm and stably maintain the lifting position. Both drive devices directly drive the core transmission components through motors, reducing intermediate transmission links, reducing energy loss and failure risk, and improving the reliability and response speed of the drive system.

[0020] A fuel injection workstation includes a fuel injection chamber and a transfer fuel injection system as described above. One end of the movable support is located in the fuel injection chamber, and the other end of the movable support extends to the outside of the fuel injection chamber. A detection switch is also provided on the fuel injection chamber, and the detection switch is connected to the control system.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] (1) This application can be installed in the area between the elevator and the parts conveying frame of the automatic production line for stamping parts. The control system is programmed to control the moving bracket to reciprocate in the area between the elevator and the parts conveying frame of the automatic production line for stamping parts. The lifting bracket is controlled to perform longitudinal lifting and lowering movements. When it reaches the elevator position, it rises and falls. The picking device on the lifting bracket is used to automatically pick up and fix the parts from the elevator of the automatic production line for stamping parts. After picking up the parts, the moving bracket moves them to the oil spraying area. The oil spraying device is programmed to automatically spray anti-splatter oil. After the oil spraying operation is completed, the moving bracket moves the parts to the area of ​​the parts conveying frame. The lifting bracket and the picking device are used to transfer the parts to the hanger of the parts conveying frame, thus completing the handling, oil spraying and transfer of automotive stamping parts, and finally achieving the function of automatic handling and spraying.

[0023] (2) This application can be precisely installed in a specific area between the elevator and the parts conveying frame of the automatic production line for stamping parts. It does not require large-scale modification of the existing production line. The application is well-suited to specific scenarios. The lifting bracket and the part picking device can automatically pick up and fix the parts. After the moving bracket picks up the parts, it can automatically move to the oil spraying area through the oil spraying device. After completion, the parts are automatically transferred to the hanger of the conveying frame. The entire process of handling, oil spraying and transfer is automated. The entire process is completed through the collaborative work of each device, which improves the continuity and efficiency of production. Moreover, the automated oil spraying can ensure the consistency and quality stability of the oil spraying material for each part. Attached Figure Description

[0036] This application can be installed in the area between the elevator and the parts conveyor of an automatic production line for stamped parts. The control system programs and controls the moving bracket 1 to reciprocate within this area. The lifting bracket 2 is controlled to move longitudinally up and down upon reaching the elevator position. The part-picking device 3 on the lifting bracket 2 automatically picks up and secures the part from the elevator. After picking up the part, it is moved to the spraying area via the moving bracket 1. The spraying device 4 is then automatically sprayed with anti-splatter oil, controlled by the control system. After spraying, the part is moved to the parts conveyor area via the moving bracket 1, and then transferred to the hanger of the parts conveyor via the lifting bracket 2 and the part-picking device 3. This completes the handling, spraying, and transfer of automotive stamped parts, ultimately achieving automatic conveying and spraying.

[0037] like Figure 1 As shown, the movable support 1 includes a base 11, a first guide rail 12 disposed on the base 11, a movable seat 13 disposed on the first guide rail 12, and a first drive device connecting the movable seat 13 and causing it to reciprocate on the first guide rail 12; the lifting support 2 includes a gantry frame 21 disposed on the movable seat 13, a second guide rail 22 disposed on the gantry frame 21, a lifting arm 23 disposed on the second guide rail 22, and a second drive device connecting the lifting arm 23 and causing it to reciprocate on the second guide rail 22; the axis of the first guide rail 12 is parallel to the mounting surface, the axis of the second guide rail 22 is perpendicular to the axis of the first guide rail 12, and the part-picking device 3 and the oil spraying device 4 are disposed on the lifting arm 23.

[0038] In this embodiment, there are two first guide rails 12, which can mutually limit and guide each other and satisfy the sliding function.

[0039] In this embodiment, there are two second guide rails 22, and the two first guide rails 12 can mutually limit and guide each other and satisfy the function of sliding.

[0040] The movable support 1 of this application achieves stable horizontal reciprocating motion through the combination of base 11, first guide rail 12, movable seat 13 and first drive device, providing a reliable foundation for overall movement; the lifting support 2 adopts the structure of gantry frame 21, second guide rail 22, lifting arm 23 and second drive device to ensure stable execution of lifting action and improve the reliability of longitudinal movement; the axis of the first guide rail 12 is parallel to the mounting surface and is generally horizontal, and the axis of the second guide rail 22 is perpendicular to the axis of the first guide rail 12 and is generally vertical, forming an orthogonal motion system, ensuring that the movement and lifting actions do not interfere with each other, and improving the accuracy of equipment operation.

[0041] like Figure 2 As shown, the fuel injection device 4 includes a third guide rail 41 mounted on the lifting arm 23, a mounting base 42 mounted on the third guide rail 41, and a third drive device 43 connected to the mounting base 42 and reciprocating on the third guide rail 41; it also includes a fourth guide rail 44 mounted on the mounting base 42, a nozzle module 45 mounted on the fourth guide rail 44, and a fourth drive device 46 connected to the nozzle module 45 and reciprocating on the fourth guide rail 44; the axis of the third guide rail 41 is parallel to the axis of the second guide rail 22, and the axis of the fourth guide rail 44 is perpendicular to the axis of the third guide rail 41.

[0042] In this embodiment, the oil injection device 4 includes two sets, which are symmetrically arranged on the lifting arm 23.

[0043] In this embodiment, both the third drive device 43 and the fourth drive device 46 in this application are telescopic cylinders that directly transmit reciprocating power.

[0044] This application uses the third guide rail 41 and the fourth guide rail 44 to form an orthogonal motion system. Combined with the third drive device 43 and the fourth drive device 46, it realizes the reciprocating motion of the nozzle module 45 in two vertical directions, flexibly covering the oil injection area. The third drive device 43 and the fourth drive device 46 independently drive the mounting base 42 and the nozzle module 45 respectively. The power transmission is direct and the movement in different directions can be precisely controlled to ensure the stability and efficiency of the oil injection action.

[0045] like Figure 1 As shown, the part retrieval device 3 includes a hanging frame 31 mounted on the lifting arm 23 for hanging parts, and a limiting bracket 32 ​​mounted on the lifting arm 23 for limiting the parts. In this way, by hanging the parts with the hanging frame 31 and limiting the parts with the limiting bracket 32, the dual structure ensures that the parts are not easily detached during the retrieval and subsequent movement, thus improving the stability of the retrieval.

[0046] Furthermore, the hanging frame 31 includes two suspension frames symmetrically arranged on the lifting arm 23, and a V-shaped limiting block 311 at the end of each suspension frame; the limiting bracket 32 ​​consists of two forks symmetrically arranged on the lifting arm 23, with the ends of the two forks flared outwards. Thus, the hanging frame 31 uses two symmetrical suspension frames with V-shaped limiting blocks at the ends, which can stably hold the parts and adapt to parts of different sizes through the V-shaped structure, enhancing versatility; the limiting bracket 32 ​​consists of two symmetrical forks with flared ends, facilitating the smooth entry of parts into the limiting range between the two forks, suitable for stamped parts with a longitudinal structure in the middle, such as... Figure 5 As shown, the car side panel 100 has a B-pillar crossbar in the middle, and the two fork arms are symmetrically arranged to balance and limit the movement from both sides, ensuring the precise position of the parts.

[0047] like Figure 1 As shown, the base 11 is also provided with a part fixing rocker arm 5 for limiting and fixing the bottom of the part, and a first stop block 6 provided on the gantry frame 21 for limiting and fixing the side wall of the part.

[0048] like Figure 4 As shown, the part fixing rocker arm 5 includes a telescopic cylinder, a connecting arm 51 rotatably connected to the output end of the telescopic cylinder at one end, and a second stop block 52 at the other end of the connecting arm 51; it also includes a pull rod 53 that is fixedly connected to the fixed end of the telescopic cylinder at one end and rotates the connecting arm 51 at the other end.

[0049] In this way, the bottom of the part is limited and fixed by the part fixing rocker arm 5 on the base 11, and the side wall of the part is limited and fixed by the first stop block 6 on the gantry frame 21, as well as the hanging bracket 31 and fork arm on the lifting arm 23, forming a multi-directional fixing system. This system can stabilize the part from different dimensions and prevent it from shifting or shaking during handling, oiling, etc., thus ensuring operational stability. On the other hand, the part fixing rocker arm 5 has an adjustable range. This structural design makes the fixing action flexible and controllable, adapting to the fixing needs of parts of different specifications.

[0050] like Figure 1 and Figure 2 As shown, it also includes a position detector 7 disposed on the base 11 for detecting the moving position of the base 11, and a part detector 8 disposed on the gantry 21 for detecting the position of the part.

[0051] In this embodiment, the movement safety of the moving bracket 1 is ensured by the positioning detector 7. At the moving end point of the first guide rail 12 on the base 11, anti-collision blocks can also be used to prevent the moving bracket 1 from derailing due to excessive travel. The parts detector 8 is used to detect whether there are parts at the picking position to prevent empty transport.

[0052] The advantages of this application are: it can be precisely installed in a specific area between the elevator and the parts conveyor in the automatic production line for stamping parts, without the need for large-scale modification of the existing production line, and the applicable scenarios are clear. The lifting bracket 2 and the part picking device 3 can automatically pick up and fix the parts. After the moving bracket 1 picks up the parts, it can automatically move to the oil spraying area through the oil spraying device 4. After completion, it automatically transfers the parts to the hanger of the conveyor. The entire process of handling, oil spraying and transfer is automated. The entire process is completed through the collaborative work of each device, which improves the continuity and efficiency of production.

[0053] Example 2

[0054] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0055] like Figure 3 As shown, the first driving device includes a gear-driven motor 14 mounted on the base 11, a rotating gear mounted on the output end of the gear-driven motor 14, and a gear transmission bar 16 whose axis is parallel to the axis of the first guide rail 12. The rotating gear meshes with the gear transmission bar 16 for transmission. The second driving device includes a lifting column drive motor 24 fixed on the gantry frame 21, a threaded screw 25 connected to the output end of the lifting column drive motor 24 and whose axis is parallel to the axis of the second guide rail 22, and a lifting nut 26 threadedly connected to the threaded screw 25. The lifting arm 23 is fixed on the lifting nut 26.

[0056] Thus, the first drive device uses a gear-driven motor 14 to drive a rotating gear, which meshes with a gear transmission bar 16 parallel to the axis of the first guide rail 12 to achieve reciprocating motion of the moving seat 13 on the first guide rail 12. The gear meshing transmission has the characteristics of precise transmission ratio and stable power transmission, ensuring that the moving seat 13 moves accurately and efficiently. The second drive device uses a lifting column drive motor 24 to drive a threaded screw 25 to rotate. The lifting nut 26, which is threadedly connected to the threaded screw 25, reciprocates on the second guide rail 22. The threaded transmission has the advantages of high transmission accuracy and good self-locking, which can accurately control the lifting action of the lifting arm 23 and stably maintain the lifting position. Both drive devices directly drive the core transmission components through motors, reducing intermediate transmission links, reducing energy loss and failure risk, and improving the reliability and response speed of the drive system.
