Abstract
Description
Technical Field
[0001] This utility model relates to the field of curing agents, and in particular to a fully automatic curing agent spraying device. Background Technology
[0002] In the industrial production sector, with the increasing demands for product surface quality and performance across various industries, the importance of hardener spraying processes is becoming increasingly prominent. Traditional hardener spraying methods largely rely on manual operation, which has several drawbacks. Firstly, manual spraying makes it difficult to ensure uniform distribution of the hardener on the workpiece surface, easily resulting in inconsistent thickness. This not only affects the product's appearance but may also lead to performance instability during use, such as defects in protective properties and wear resistance. Secondly, manual operation is inefficient, especially under large-scale production demands, failing to meet the requirements of efficient and rapid production pace, increasing the company's labor and time costs. Furthermore, long-term exposure to hardeners and other chemicals may pose potential health hazards to operators.
[0003] In existing technologies, traditional automatic curing agent spraying devices use robotic arms to transport the workpiece, which is automatically conveyed to the spraying area. Then, a pump delivers the curing agent from the storage tank to the nozzle through pipelines. At the nozzle, according to the set spraying mode, the atomizing device in the nozzle disperses the curing agent into tiny droplets, forming a mist spray, which allows the curing agent to more evenly cover the complex-shaped surface of the workpiece.
[0004] However, in the existing technology, the internal support structure of traditional automatic curing agent spraying devices is usually fixed, which can only support and spray workpieces of specific shapes and sizes. It cannot adapt to the placement and spraying of workpieces of different sizes, resulting in low equipment adaptability. Therefore, a fully automatic curing agent spraying device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a fully automatic curing agent spraying device, which aims to improve the problem that the existing equipment has low adaptability and cannot support workpieces of different sizes and shapes.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A fully automatic curing agent spraying device includes a spraying chamber, a placement rack on the front side of the spraying chamber, a baffle fixedly connected inside the spraying chamber, an I-beam support frame fixedly connected to the bottom of the spraying chamber, multiple slots inside the I-beam support frame, multiple sliding blocks slidably connected inside the I-beam support frame, bolts threaded inside the sliding blocks, a support plate fixedly connected to the top of the bolts, a wedge rotatably connected to the bottom of the bolts, a guide rod fixedly connected inside the sliding blocks, two locking blocks slidably connected to the outside of the guide rod, a spring sleeved on the outside of the guide rod, and a rotating assembly inside the spraying chamber for uniformly spraying the coating onto the spraying structure.
[0008] As a further description of the above technical solution:
[0009] A robotic arm is installed on the front side of the spraying chamber, and a gripper is fixedly connected to the bottom of the robotic arm.
[0010] As a further description of the above technical solution:
[0011] One end of the spring is fixedly connected to the outside of one of the locking blocks, and the other end of the spring is fixedly connected to the outside of the other locking block.
[0012] As a further description of the above technical solution:
[0013] The outside of the wedge block contacts the outside of the locking block, and the outside of the two locking blocks engages with the inside of the locking groove.
[0014] As a further description of the above technical solution:
[0015] The rotating assembly includes a mounting frame, which is externally fixedly connected to the interior of the spraying chamber. A rotating frame is rotatably connected to the bottom of the mounting frame, and a spraying rod is fixedly connected to the interior of the rotating frame. A rotating plate is rotatably connected to the rear side of the rotating frame.
[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, rotating the support plate causes the bolt to rotate, thereby achieving a spiral upward motion, which in turn causes the wedge to rise, losing the squeezing force on the two locking blocks. Then, the reaction force of the spring causes the two locking blocks to slide to the same side and retract into the sliding block. The position of the sliding block can then be adjusted to accommodate workpieces of different sizes. Finally, rotating the support plate in the opposite direction squeezes the locking blocks to complete the fixing. The simple mechanical transmission principle enables fast and precise adjustment, greatly improving the versatility and practicality of the equipment. It eliminates the need for multiple support devices for workpieces of different specifications, effectively saving equipment costs and production space.
[0024] 2. In this utility model, the power switch of the starting motor drives the turntable to rotate, thereby causing the first rotating plate to move in a circular motion, pulling the sliding plate to slide back and forth inside the limiting groove, and finally driving the second rotating plate to control the rotating frame to rotate back and forth, so as to achieve uniform spraying at multiple angles, avoiding the problem of inconsistent coating thickness caused by spraying dead corners, effectively improving the coating quality, and making the protective effect of the workpiece more reliable and durable.

Detailed Implementation
[0032] 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.
[0033] Reference Figures 1 to 3 One embodiment of this utility model is a fully automatic curing agent spraying device, which includes a spraying chamber 1. The spraying chamber 1 is rectangular in shape and made of sturdy stainless steel. It has good sealing and stability and can effectively prevent the curing agent from evaporating and diffusing outward during the spraying process, providing a relatively closed and safe environment for the internal spraying operation. A placement rack 2 is provided on the front side of the spraying chamber 1. The placement rack 2 is used to provide a support base for the workpiece to be sprayed. A baffle 23 is fixedly connected inside the spraying chamber 1. The baffle 23 is an inclined flat plate, which can effectively reduce the spraying of hardener and its impact on the external environment. An I-beam support frame 5 is fixedly connected to the bottom of the spraying chamber 1. The I-beam support frame 5 is I-shaped and made of high-quality steel, thus providing support for the workpiece during spraying. Multiple slots 6 are opened inside the I-beam support frame 5. The slots 6 are block-shaped grooves and are fixed by the engagement of subsequent structures. Multiple sliding blocks 7 are slidably connected inside the I-beam support frame 5. The sliding blocks 7 are block-shaped and match the sliding grooves opened inside the I-beam support frame 5. The position can be adjusted by sliding to adapt to the support of different types and sizes of workpieces.
[0034] Reference Figures 2 to 4The sliding block 7 has a bolt 8 internally threaded, and the bolt 8 has threads on its outside. It can be raised and lowered by rotation to adjust the fixed state. The top of the bolt 8 is fixedly connected to a support plate 9, which is a small flat plate used to directly contact the workpiece for support. The bottom of the bolt 8 is rotatably connected to a wedge 10, which has two beveled edges on its bottom. It generates a squeezing force by sliding up and down, pushing the horizontal structure to slide. The sliding block 7 has a guide rod 11 internally fixedly connected. The guide rod 11 is cylindrical and provides guidance and limit for the subsequent elastic structure. The guide rod 11 has two locking blocks 13 externally slidably connected. The two locking blocks 13 also have beveled edges on their adjacent sides. They are locked by the contact and squeezing of the wedge 10. The guide rod 11 is fitted with a spring 12 externally. The spring 12 is used to provide a reaction force to drive the two locking blocks 13 to slide back. The spraying chamber 1 is equipped with a rotating assembly that drives the spraying structure to spray evenly.
[0035] Reference Figure 1 and Figure 4 A robotic arm 3 is installed on the front side of the spraying chamber 1. The robotic arm 3 adopts an advanced multi-joint mechanical structure design, and its overall shape is similar to a human arm. It has multiple degrees of freedom and flexible movement capabilities to transport workpieces. A gripper 4 is fixedly connected to the bottom of the robotic arm 3. The gripper 4 is used to pick up workpieces. One end of the spring 12 is fixedly connected to the outside of one of the locking blocks 13, and the other end of the spring 12 is fixedly connected to the outside of the other locking block 13, thereby providing a reaction force to drive the two locking blocks 13 to slide back in opposite directions. The outside of the wedge block 10 contacts the outside of the locking block 13, changing the vertical force into a force that pushes the two locking blocks 13 to slide horizontally. The outside of the two locking blocks 13 engages with the inside of the slot 6, thereby fixing the sliding block 7.
[0036] Reference Figure 2 and Figure 5The rotating assembly includes a mounting frame 14, which is externally fixedly connected to the interior of the spray chamber 1. The mounting frame 14 is T-shaped and contains pipes for transporting curing agent. A rotating frame 15 is rotatably connected to the bottom of the mounting frame 14, providing a mounting base for the subsequent spraying structure. A spraying rod 16 is fixedly connected inside the rotating frame 15, and multiple nozzles are mounted on the spraying rod 16 to evenly spray the curing agent. A rotating plate 21 is rotatably connected to the rear side of the rotating frame 15. The rotating plate 21 is elongated and its movement is driven by the subsequent structure, causing the rotating frame 15 to swing back and forth. A motor 17 is fixedly connected inside the spray chamber 1, providing power for the reciprocating swing. The drive end of the motor 17 is fixedly connected to the rotating frame 1. A turntable 18 is fixedly connected to the spray booth 1. The turntable 18 is disc-shaped and is used to transmit the power of the motor 17. A rotating plate 19 is rotatably connected to the outside of the turntable 18. The rotating plate 19 is driven by the turntable 18 to make a circular motion. A limiting groove 20 is fixedly connected inside the spray booth 1. The limiting groove 20 is rectangular and has a space inside to accommodate the sliding of the subsequent structure and provide a limit. A sliding plate 22 is slidably connected inside the limiting groove 20. One end of the sliding plate 22 is fixedly connected to the outside of the rotating plate 21, and the other end of the sliding plate 22 is rotatably connected to the outside of the rotating plate 19. The sliding plate 22 is driven by the rotating plate 19 to slide back and forth, thereby driving the rotating plate 21 to pull the rotating frame 15 to swing back and forth, so as to achieve a uniform spraying effect.
[0037] Working principle: First, the operator places the workpiece to be coated with curing agent on the top of the placement rack 2. The robotic arm 3 drives the gripper 4 to hold the workpiece and place it on the top of the I-beam support frame 5 inside the spraying chamber 1. The support plate 9 supports the workpiece, and then spraying is performed. Since the workpieces are of different sizes, the bolt 8 is rotated by rotating the support plate 9 in the opposite direction, thereby realizing a spiral upward movement, which drives the wedge block 10 to rise, losing the squeezing force on the two clamping blocks 13. Then, the reaction force of the spring 12 drives the two clamping blocks 13 to slide to the same side and retract into the sliding block 7. Then, the position of the sliding block 7 is adjusted by sliding to adapt to the support of workpieces of different sizes. Finally, the support plate 9 is rotated in the opposite direction to drive the bolt 8 and wedge block 10 to move downward, and the clamping blocks 13 are squeezed out and locked into the groove 6 to complete the fixation. The simple mechanical transmission principle achieves fast and precise adjustment, which greatly improves the versatility and practicality of the equipment. There is no need to equip multiple support devices for workpieces of different specifications, which effectively saves equipment costs and production space.
[0038] Secondly, when the spraying rod 16 is turned on for spraying, the power switch of the motor 17 is turned on to drive the turntable 18 to rotate, which in turn drives the rotating plate 19 to rotate, pulling the sliding plate 22 to slide back and forth inside the limiting groove 20. Finally, the rotating plate 21 is driven to control the rotating frame 15 to rotate back and forth, so as to achieve uniform spraying from multiple angles. The multi-angle spraying mode can ensure that the curing agent fully and evenly covers all surfaces of the workpiece, avoiding the problem of inconsistent coating thickness caused by spraying dead corners, effectively improving the coating quality, and making the protective effect of the workpiece more reliable and durable.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
