Description

Technical Field

[0001] This utility model belongs to the field of injection molding part spraying technology, and in particular relates to a mobile spraying device for automotive injection molding parts. Background Technology

[0002] Automotive injection-molded parts painting is the process of giving plastic parts an attractive color and a durable surface. Workers first clean and dust the injection-molded parts, then hang them on the assembly line. Painters, holding spray guns, use their experience to evenly coat the surface of the parts with the prepared paint. This process requires skill to ensure a smooth paint finish without runs or orange peel. The painted parts are then sent into a long drying tunnel, where they are baked at a specific temperature and time until the paint finally cures, becoming glossy and strong.

[0003] When a vehicle injection-molded part is damaged and needs to be purchased, the production line will not be turned on for processing. Instead, the plastic part is molded using injection molding equipment, and then its surface is sprayed manually before being sent to the drying room for drying. The overall efficiency is poor.

[0004] To address the aforementioned problems, this application proposes a mobile spraying device for automotive injection molded parts. Utility Model Content

[0005] The purpose of this invention is to provide a mobile spraying device for automotive injection molded parts, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a mobile spraying device for automotive injection molded parts, comprising a frame on which two discs driven by a rotary motor are rotatably connected. The discs are symmetrically arranged, and each disc has three positioning seats fixed on it. Right-angle locking blocks are installed on the positioning seats. The two positioning seats cooperate with the right-angle locking blocks to clamp the long injection molded parts. The frame is also equipped with a horizontally sliding spraying mechanism and a drying mechanism. The three sets of positioning seats are connected to the long injection molded parts, corresponding to three workstations: loading and unloading, spraying, and drying.

[0008] Furthermore, the positioning seat has a countersunk groove and a corresponding connecting lug for the positioning groove, and the right-angle locking block has a sliding groove on the side away from the positioning groove to slide with the right-angle locking block.

[0009] Furthermore, the bottom of the right-angle locking block is an inclined surface, and a screw is rotatably connected to the right-angle locking block, the screw being threadedly connected to the positioning seat.

[0010] Furthermore, the end of the screw away from the right-angle locking block passes through the positioning seat and is fixed with a screw wheel.

[0011] Furthermore, the frame is provided with a movable frame, the two ends of which are fixed to the spraying mechanism and the drying mechanism respectively. Two linear guide sleeves are fixed on the movable frame, and two support guide rods are fixed on the frame and slidably connected to the linear guide sleeves.

[0012] Furthermore, a threaded sleeve is fixed on the movable frame, and a long lead screw is rotatably connected to the frame and threadedly connected to the threaded sleeve. A movable motor connected to the long lead screw is also fixed on the side of the frame.

[0013] Furthermore, a controller is installed on the side of the frame, and the controller is electrically connected to the rotary motor and the moving motor.

[0014] This utility model has the following beneficial effects:

[0015] This invention features three sets of positioning seats on a disc, each capable of holding a long injection molded part, thus forming three workstations for loading / unloading, spraying, and drying. These three workstations can operate simultaneously, thereby improving spraying efficiency. Furthermore, the movable structure can accommodate long, strip-shaped injection molded parts.

[0016] This utility model improves spraying efficiency by setting the spraying mechanism and drying mechanism to a synchronous moving structure. During the movement, the spraying mechanism performs spraying work, while the drying mechanism performs curing work. Moreover, the overall volume is small because the three stations are rotated.

[0017] This utility model enables the simple and stable assembly and disassembly of long injection molded parts 4 through the cooperation of positioning seat 2 and right-angle locking block 3, taking into account both efficiency and processing stability.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] 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.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1 - Figure 4 As shown, this utility model is a mobile spraying device for automotive injection molded parts, including a frame 1. A disc 11 driven by a rotary motor 12 is rotatably connected to the frame 1. There are two discs 11 arranged symmetrically. Three positioning seats 2 are fixed on each of the two discs 11. Right angle locking blocks 3 are installed on the positioning seats 2. The two positioning seats 2 cooperate with the right angle locking blocks 3 to clamp the long injection molded part 4. The frame 1 is also provided with a horizontally sliding spraying mechanism 6 and a drying mechanism 7. The three sets of positioning seats 2 are connected to the long injection molded part 4 and correspond to the loading and unloading, spraying and drying stations. In this embodiment, the drying mechanism 7 includes a hot air dryer and a nozzle. The nozzle is directed towards the spraying surface of the long injection molded part 4 to perform the drying work.

[0029] Furthermore, the positioning seat 2 is provided with a recessed groove 21 and a positioning groove 211 corresponding to the connecting lug 41. The right-angle locking block 3 is provided with a sliding groove 212 on the side away from the positioning groove 211, which slides and cooperates with the right-angle locking block 3. The recessed groove 21 and the positioning groove 211 can position the long injection molded part 4 from multiple angles.

[0030] Furthermore, the bottom of the right-angle locking block 3 is a slope 31, and a screw 32 is rotatably connected to the right-angle locking block 3. The screw 32 is threadedly connected to the positioning seat 2. During assembly, the screw 32 is spiraled outward from the inside of the groove 21, and then fixed to the screw wheel 33 by bolts. The slope 31 at the bottom of the right-angle locking block 3 cooperates with the sliding groove 212 to prevent the right-angle locking block 3 from coming off from the side.

[0031] Furthermore, the end of the screw 32 away from the right-angle locking block 3 passes through the positioning seat 2 and is fixed with a screw wheel 33.

[0032] Furthermore, a movable frame 5 is provided on the frame 1. The two ends of the movable frame 5 are fixed to the spraying mechanism 6 and the drying mechanism 7, respectively. Two linear guide sleeves 51 are fixed on the movable frame 5. Two support guide rods 13 are fixed on the frame 1 and slidably connected to the linear guide sleeves 51. In this embodiment, the two sets of linear guide sleeves 51 and support guide rods 13 can ensure that the movable frame 5, the spraying mechanism 6 and the drying mechanism 7 move smoothly on the frame 1, ensuring the quality of spraying and drying.

[0033] Furthermore, a threaded sleeve 52 is fixed on the movable frame 5, and a long lead screw 14 is rotatably connected to the threaded sleeve 52. A movable motor 15 connected to the long lead screw 14 is also fixed on the side of the frame 1. Through the threaded structure, the smooth movement of the spraying mechanism 6 and the drying mechanism 7 can be ensured, thereby achieving smooth spraying and drying.

[0034] Furthermore, a controller 8 is installed on the side of the frame 1. The controller 8 is electrically connected to the rotary motor 12 and the moving motor 15. The controller 8 controls the forward and reverse rotation of the rotary motor 12, thereby driving the spraying mechanism 6 and the drying mechanism 7 to reciprocate. The moving motor 15 controls the rotation of the positioning seat 2 and the long injection molded part 4. One revolution of the disc 11 is divided into 3 rotations, corresponding to 3 sets of positioning seats 2.

[0035] Understandably, this utility model, by setting three sets of positioning seats on the disc, can clamp long injection molded parts separately, forming three synchronously operating workstations for loading and unloading, spraying, and drying, effectively improving processing efficiency; the spraying mechanism and the drying mechanism adopt a synchronous moving design, completing spraying and curing sequentially during movement, which not only saves space but also adapts to the processing needs of long strip injection molded parts; at the same time, the cooperation structure between the positioning seat and the right-angle locking block takes into account both ease of assembly and disassembly and clamping stability, enhancing the stability of the processing while ensuring efficiency.

[0036] One specific application of this embodiment is as follows: The connecting ears 41 at both ends of the long injection molded part 4 are placed into the recesses 21 of the two positioning seats 2, and then the connecting ears 41 are pushed into the positioning grooves 211. At this time, the screw 32 is turned by the screw wheel 33. The screw 32 pushes the right-angle locking block 3 to slide in the sliding groove 212 through the spiral between the screw and the positioning seat 2. The right-angle locking block 3 holds the connecting ears 41 against the positioning groove 211. At the same time, the structure of the right-angle locking block 3 can form a barrier at the position of the recess 21, ensuring that the long injection molded part 4 The machine is stabilized on the positioning seat 2; the rotating motor 12 drives the frame 1, positioning seat 2, and long injection molded part 4 to rotate to the spraying station. At this time, the long injection molded part 4 is facing the spraying mechanism 6, and the spraying work is carried out by the spraying mechanism 6; after the long injection molded part 4 at the position of the spraying mechanism 6 is sprayed, it rotates to the drying station. At this time, the spraying mechanism 6 is facing the drying mechanism 7. When there are long injection molded parts 4 at the positions of the spraying mechanism 6 and the drying mechanism 7, the spraying mechanism 6 and the drying mechanism 7 can work simultaneously.

[0037] The movement of the spraying mechanism 6 and the drying mechanism 7: After the moving motor 15 is working, it drives the long lead screw 14 to rotate. The threaded sleeve 52 drives the moving frame 5 to move horizontally through the screw of the long lead screw 14. The linear guide sleeve 51 slides outside the support guide rod 13, thereby driving the spraying mechanism 6 and the drying mechanism 7 to reciprocate synchronously.

[0038] It should be noted that this invention needs to be operated and used in a cleanroom.
