Description

Technical Field

[0001] This invention relates to the field of automotive interior parts spraying technology, specifically to a spraying device for the production of automotive interior parts. Background Technology

[0002] In the production of automotive interior parts, spraying is a crucial step in ensuring product appearance quality. Traditional spraying equipment generally suffers from the following problems: In manually assisted spraying equipment, the spraying bracket is mostly a fixed structure, unable to flexibly adjust its deflection angle, and always remains in a horizontal position. This makes it difficult to spray areas such as the back edges of automotive interior parts, creating spraying blind spots and seriously affecting the spraying effect and product quality. Some adjustable-angle spraying devices lack a reliable self-locking function, making it difficult for the spraying bracket to stably rotate around its own axis after deflection, failing to achieve omnidirectional spraying and resulting in low work efficiency. These problems greatly restrict the efficiency and quality of automotive interior part spraying operations, failing to meet the demands of modern production for high precision, high efficiency, and low labor intensity. Summary of the Invention

[0007] Preferably, a shaft-connecting mounting ring is installed on both the first and second rotating shafts. The shaft-connecting mounting ring on the second rotating shaft is fixedly connected to the second rotating shaft, and the other shaft-connecting mounting ring is vertically slidably connected to the first rotating shaft. A transmission plate is installed on the side of each shaft-connecting mounting ring, and the shaft-connecting mounting ring is rotatably connected to the transmission plate. The two ends of the hinged connecting rod are respectively hinged to the two transmission plates. The top of the lifting rod is fixedly connected to the transmission plate located below. A limiting ring is provided on the first rotating shaft to limit the sliding distance of the shaft-connecting mounting ring.

[0008] Preferably, the control room is provided with a vertical slide groove for the control lever to slide, and a horizontal locking groove is provided on the side of the vertical slide groove. An elastic abutment strip for locking the control lever is provided in the horizontal locking groove. A hinge seat is provided in the middle of the control lever. The hinge seat is fixedly installed in the spraying chamber. The control lever consists of a transmission rod, a horizontal deflection hinge joint, and a deflection hinge rod. One end of the transmission rod is connected to the lifting plate or lifting rod, and the other end of the transmission rod is hinged to the hinge seat. The horizontal deflection hinge joint is fixedly installed at the end of the transmission rod near the hinge seat. One end of the deflection hinge rod is connected to the transmission rod through the horizontal deflection hinge joint, and the other end of the deflection hinge rod extends outward through the control room panel.

This effectively covers areas that are difficult for traditional devices to reach, such as the back edges of automotive interior parts, avoiding incomplete spraying. Simultaneously, when the spraying bracket deflects, the engagement of the lifting plate and the driven gear causes the spraying bracket to rotate around its deflected axis, achieving omnidirectional spraying. This further reduces blind spots and significantly improves spray uniformity and product quality.

The control lever in the control room can be locked through the horizontal locking groove and the elastic clamping strip, which can firmly fix the deflection angle and rotation state of the spraying bracket, prevent the angle from shifting due to vibration or accidental touch during operation, and ensure the stability of spraying accuracy.

[0017] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-8 The illustrated spraying device for producing automotive interior parts includes a spraying chamber 1, a mounting plate 2 within the spraying chamber 1, a rotating rod 3 rotatably mounted on the mounting plate 2, a spraying bracket 4 mounted on the top of the rotating rod 3, the rotating rod 3 and the spraying bracket 4 connected by a universal joint 5, a lifting plate 6 and a driven gear 7 coaxially mounted on the rotating rod 3, the driven gear 7 being mounted below the mounting plate 2, the lifting plate 6 sliding vertically with the rotating rod 3 and rotating synchronously with it, the lifting plate 6 being able to engage with the driven gear 7, a hinged connecting rod 8 and a lifting rod 9 being provided on the side of the rotating rod 3, one end of the hinged connecting rod 8 being drivenly connected to the spraying bracket 4, and the other end being drivenly connected to the lifting rod 9, a control room being provided on the side of the spraying chamber 1, the control room containing two control rods 10 that can deflect in the vertical plane, one control rod 10 being drivenly connected to the lifting plate 6, and the other control rod 10 being drivenly connected to the lifting rod 9, the control rods 10 being able to lock with the control room panel.

[0019] The spraying device of this invention has a top of rotating rod 3 connected to a spraying bracket 4 via a universal joint 5, enabling multi-angle deflection of the spraying bracket 4. A lifting plate 6 can slide vertically along the rotating rod 3 and rotates synchronously with it. By engaging or disengaging with the driven gear 7, it controls whether the rotating rod 3 drives the spraying bracket 4 to rotate. When the lifting rod 9 rises or falls, it drives the spraying bracket 4 to deflect around the universal joint 5 via a hinged connecting rod 8, achieving angle adjustment. Two control rods 10 are respectively connected to the lifting plate 6 and the lifting rod 9. The operator can manually adjust the lifting plate 6 (controlling rotation) and the lifting rod 9 (controlling deflection) in the vertical plane by using the deflection control rods 10. The control rods 10 can also be locked to the control panel to fix the state.

[0020] The spraying bracket 4 of this invention can flexibly adjust its deflection angle to effectively cover the back edge area, avoiding incomplete spraying and improving spray uniformity and product quality. The locking function of the control lever 10 and the control panel can fix the deflection angle and rotation state of the spraying bracket 4, preventing angle deviation due to vibration or accidental touch during operation and ensuring spraying accuracy. After deflection, the spraying bracket 4 is controlled to rotate around the deflection axis, reducing spray dead angles and improving work efficiency and coverage.

[0021] This structure combines mechanical linkage with manual control, which solves the angle limitation problem of traditional brackets and is suitable for production scenarios with high requirements for spraying accuracy and efficiency, such as automotive interior parts.

[0022] The control room is provided with a vertical slide groove 11 for the control lever 10 to slide. A horizontal locking groove 12 is provided on the side of the vertical slide groove 11. An elastic abutment strip 13 for locking the control lever 10 is provided in the horizontal locking groove 12. The control lever 10 is composed of a transmission rod 14, a horizontal deflection hinge joint 15 and a deflection hinge rod 16. One end of the transmission rod 14 is connected to the lifting plate 6 or the lifting rod 9. The other end of the transmission rod 14 is hinged to the spray chamber 1 through the hinge seat 17. The horizontal deflection hinge joint 15 is fixedly installed at the end of the transmission rod 14 near the hinge seat 17. One end of the deflection hinge rod 16 is connected to the transmission rod 14 through the horizontal deflection hinge joint 15. The other end of the deflection hinge rod 16 extends outward through the control room panel. A control handle is provided at the end of the deflection hinge rod 16 away from the transmission rod 14.

[0023] The vertical slide groove 11 allows the control rod 10 to slide vertically to adjust the lifting plate 6 or the lifting rod 9. Once the control rod 10 reaches the target position, it can be pushed into the horizontal locking groove 12, where the friction of the elastic retaining strip 13 locks it in place, preventing accidental movement of the control rod 10. The control rod 10 can be directly pulled to freely deflect in the vertical plane, enabling real-time adjustment of the lifting plate 6 (controlling rotation) or the lifting rod 9 (controlling deflection). When a fixed angle is required, the control rod 10 is pushed horizontally into the horizontal locking groove 12. The elastic retaining strip 13 within the groove tightly presses against the control rod 10, limiting its displacement in the vertical and horizontal planes through friction. This ensures that the deflection position of the control rod 10 is completely fixed in the locked state, preventing angle loosening during operation. The horizontal deflection hinge 15 provides the control lever 10 with a horizontal degree of rotation. The horizontal deflection hinge 15 serves only as a guide for the locking operation and does not interfere with the adjustment accuracy in the vertical plane, ensuring that the deflection action of the control lever 10 precisely corresponds to the angular change of the spraying bracket 4. The transmission rod 14 is connected to the spraying chamber 1 via the hinge seat 17, forming a stable fulcrum, ensuring that the vertical deflection force of the control lever 10 is transmitted to the lifting plate 6 or the lifting rod 9, achieving precise movement of the spraying bracket 4.

[0024] When the operator holds the control handle, they can directly pull the control lever 10 to adjust the angle in the vertical plane. After it is in place, pushing it horizontally will lock it. After locking, the deflection angle of the control lever 10 remains unchanged. To unlock, pulling it horizontally in the opposite direction will restore the adjustment function. The operator can complete the adjustment and locking actions with one hand, reducing the complexity of operation and improving the efficiency of mass production.

[0025] A transmission seat 18 is provided on the side of the transmission rod 14 away from the hinge seat 17. A transmission collar 19 is hinged on the transmission seat 18. The transmission rod 14 is slidably connected to the transmission collar 19. The top of the transmission seat 18 is fixedly connected to the lifting rod 9 or the lifting plate 6.

[0026] When the control lever 10 drives the transmission rod 14 to swing around the hinge seat 17, the transmission collar 19 slides on the transmission rod 14 to adapt to the angle change of the transmission rod 14 and avoid motion interference. At the same time, the swing of the transmission rod 14 is converted into the lifting and lowering motion of the transmission seat 18, thereby driving the lifting rod 9 or the lifting plate 6 to move, realizing the angle adjustment or rotation control of the spraying bracket 4.

[0027] The rotating rod 3 is composed of a first rotating shaft 20 and a second rotating shaft 21. The first rotating shaft 20 is rotatably connected to the mounting plate 2. The top of the second rotating shaft 21 is fixedly connected to the spraying bracket 4. The top of the first rotating shaft 20 is fixedly connected to one end of the universal joint 5. The bottom of the second rotating shaft 21 is fixedly connected to the other end of the universal joint 5.

[0028] When the spraying bracket 4 needs to be deflected, the second rotating shaft 21 can rotate flexibly around the universal joint 5, while the first rotating shaft 20 can still maintain its own rotation state, ensuring that while the spraying bracket 4 is deflected, the rotation of the first rotating shaft 20 can be transmitted to the second rotating shaft 21 through the universal joint 5, driving the spraying bracket 4 to rotate around the deflected axis.

[0029] A shaft mounting ring 22 is installed on both the first rotating shaft 20 and the second rotating shaft 21. The shaft mounting ring 22 on the second rotating shaft 21 is fixedly connected to the second rotating shaft 21. The other shaft mounting ring 22 is vertically slidably connected to the first rotating shaft 20. A transmission plate 23 is installed on the side of the shaft mounting ring 22. The shaft mounting ring 22 is rotatably connected to the transmission plate 23. The two ends of the hinged connecting rod 8 are respectively hinged to the two transmission plates 23. The top of the lifting rod 9 is fixedly connected to the transmission plate 23 located below. A limiting ring 24 is provided on the first rotating shaft 20 to limit the sliding distance of the shaft mounting ring 22.

[0030] When the lifting rod 9 is raised and lowered under the drive of the control rod 10, it drives the lower transmission plate 23 to move synchronously. Through the transmission of the hinged connecting rod 8, the movement of the lower transmission plate 23 is transmitted to the upper transmission plate 23. The transmission plate 23 and its connected shaft mounting ring 22 drive the second rotating shaft 21 to deflect, thereby realizing the angle adjustment of the spraying bracket 4. The shaft mounting ring 22 on the first rotating shaft 20 slides in conjunction with the limiting ring 24 to provide a stable stroke constraint for the angle adjustment, making the deflection angle of the spraying bracket 4 easier to control precisely, effectively eliminating the spraying blind spot on the back edge of the automotive interior parts, and improving the spraying uniformity.

[0031] The control room is provided with a vertical slide groove 11 for the control lever 10 to slide. A horizontal locking groove 12 is provided on the side of the vertical slide groove 11. An elastic abutment strip 13 for locking the control lever 10 is provided in the horizontal locking groove 12. A hinge seat 17 is provided in the middle of the control lever 10. The hinge seat 17 is fixedly installed in the spraying chamber 1. The control lever 10 is composed of a transmission rod 14, a horizontal deflection hinge joint 15 and a deflection hinge rod 16. One end of the transmission rod 14 is connected to the lifting plate 6 or the lifting rod 9. The other end of the transmission rod 14 is hinged to the hinge seat 17. The horizontal deflection hinge joint 15 is fixedly installed at the end of the transmission rod 14 near the hinge seat 17. One end of the deflection hinge rod 16 is connected to the transmission rod 14 through the horizontal deflection hinge joint 15. The other end of the deflection hinge rod 16 is set outward through the control room panel. A control handle is provided at the end of the deflection hinge rod 16 away from the transmission rod 14.

[0032] The operator holds the control handle and pulls the deflection hinge rod 16 to slide within the vertical slide groove 11. This drives the transmission rod 14 to swing via the hinge seat 17, which in turn drives the lifting plate 6 or the lifting rod 9 to adjust the angle or control the rotation of the spraying bracket 4. When the target position is reached, the deflection hinge rod 16 is pushed through the horizontal deflection hinge joint 15 into the horizontal locking groove 12. The elastic clamping strip 13 locks the control rod 10, ensuring a stable position. To unlock, pulling in the opposite direction restores the adjustment function. The vertical slide groove 11 guides the control rod 10 to slide, and combined with the fulcrum effect of the hinge seat 17, the angle adjustment of the spraying bracket 4 is more precise. The elastic clamping strip 13 in the horizontal locking groove 12 securely locks the adjustment angle, preventing displacement due to vibration during operation and completely solving the problem of blind spots in the back edge spraying.

[0033] The lifting plate 6 is provided with a rod 29, and the driven gear 7 is provided with a slot 30 that engages with the rod 29. The slot 30 has a tapered opening 31 at the opening. The lower half of the rotating rod 3 has a vertical sliding groove 32 on its outer side wall. The inner ring of the lifting plate 6 has a transmission slider 33 that is slidably disposed in the vertical sliding groove 32.

[0034] When the lifting plate 6 moves vertically close to the driven gear 7, the insertion rod 29 can be precisely inserted into the slot 30 along the conical opening 31, reducing the difficulty of alignment and ensuring a smooth engagement process. The structure of the vertical slide 32 and the transmission slider 33 allows the lifting plate 6 to slide vertically along the rotating rod 3 (achieving engagement or disengagement with the driven gear 7), and through the cooperation of the transmission slider 33 and the vertical slide 32, it ensures that the lifting plate 6 rotates synchronously with the rotating rod 3, ensuring uninterrupted power transmission.

[0035] The lower half of the spraying chamber 1 is also provided with a mounting bracket, a drive motor 26 and a drive gear 27. The mounting bracket is fixedly mounted on the mounting plate 2. The drive motor 26 is located at the bottom of the spraying chamber 1. The drive gear 27 is rotatably mounted on the mounting bracket. The output end of the drive motor 26 is fixedly connected to the drive gear 27. The drive gear 27 meshes with the driven gear 7. The mounting bracket is provided with a rotating sleeve 28. The driven gear 7 is mounted on the rotating sleeve 28.

[0036] After the drive motor 26 starts, it drives the drive gear 27 to rotate, and the drive gear 27 drives the driven gear 7 that meshes with it to rotate, so that the driven gear 7 rotates together with the rotating sleeve 28. When the lifting plate 6 is engaged with the driven gear 7, the rotation of the driven gear 7 will drive the lifting plate 6 and the rotating rod 3 to rotate synchronously, and then drive the spraying bracket 4 to rotate around the axis.

[0037] The mounting plate 2 is vertically provided with a limiting plate 25 to limit the position of the transmission plate 23, and the transmission plate 23 is located between the two limiting plates 25.

[0038] The limiting plate 25 restricts the shaking of the transmission plate 23 and ensures that the transmission plate 23 will not deviate when the rotating rod 3 rotates, thus ensuring the stability of the spraying bracket 4.

[0039] The spraying bracket 4 is detachably mounted with several evenly distributed support rods 34, and the top of the support rods 34 is provided with elastic clamping claws 35.

[0040] The flexible clamping claw 35 can firmly clamp the interior parts, preventing them from loosening or shifting due to equipment vibration during the spraying process.

[0041] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
