Description

Technical Field

[0001] This utility model relates to the technical field of spraying lines, and in particular to a hanging automatic gun adjustment spraying device. Background Technology

[0002] In the field of spraying equipment, with the development of the manufacturing industry, the requirements for efficiency, precision, and safety in spraying operations are increasing. Traditional spraying equipment has revealed many problems during operation. In the past, spray gun operating parameters, such as position and angle, were mostly adjusted manually. When facing the spraying needs of different products, the parameters of each spray gun had to be readjusted and samples made every time the product was changed. This process not only consumes a lot of time and delays the production cycle, but also leads to high debugging costs, which greatly affects production efficiency and enterprise cost control.

[0003] While subsequent automatic spray gun adjustment technologies have emerged, significant drawbacks remain. In some devices, the drive motor is installed too close to the spray gun. During spraying operations, flammable and explosive substances such as paint are often present around the spray gun, and the proximity of the motor to the spray gun poses a safety hazard, threatening production safety. Furthermore, existing technologies have limited adjustment range for the spray gun module position, making it difficult to meet the diverse spraying needs of complex products. They also have limitations in spraying coverage for large or irregularly shaped workpieces, failing to achieve comprehensive and precise spraying. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0005] This utility model provides a hanging automatic spray gun adjustment device, including a frame, a rotating platform installed below the frame, and an adjustment device installed on the frame and extending towards the rotating platform. A spray gun is mounted on the drive end of the adjustment device, and the spray gun is used to perform spraying operations on materials on the rotating platform. The adjustment device is used to adjust the operating parameters of the spray gun. The adjustment device is equipped with a control module, which is used to record the operating parameters of the spray gun and control the adjustment device to adjust the spray gun according to the operating parameters.

[0006] Furthermore, the adjustment device is also provided with a transverse movement component, a longitudinal movement component, and an angle component. The transverse movement component is mounted on the frame, the longitudinal movement component is mounted on the drive end of the transverse movement component, the angle component is mounted on the drive end of the longitudinal movement component, and the spray gun is mounted on the drive end of the angle component.

[0007] Furthermore: the transverse component is provided with a transverse support and a transverse linear module. One end of the transverse support is detachably fixed to the frame by bolts, and the other end is used to install the transverse linear module. The longitudinal component is provided with a longitudinal linear module. The slide portion of the longitudinal linear module is fixedly connected to the slide portion of the transverse linear module. The angle component is installed on the base of the longitudinal linear module.

[0008] Furthermore: the angle assembly includes a first motor, a first connecting rod, and a transmission mechanism. The first motor and the transmission mechanism are respectively installed at both ends of the base of the longitudinal linear module. One end of the first connecting rod is connected to the output shaft of the first motor, and the other end is connected to the input shaft of the transmission mechanism. The spray gun is installed on the output shaft of the transmission mechanism.

[0009] Furthermore, the angle assembly also includes an angle bracket, a timing belt, a first timing pulley, and a second timing pulley. The angle bracket is mounted on the transmission mechanism, the first timing pulley and the second timing pulley are rotatably connected to the angle bracket, the timing belt is sleeved on the first timing pulley and the second timing pulley, the first timing pulley is drively connected to the output shaft of the transmission mechanism, and the spray gun is mounted on the second timing pulley.

[0010] Furthermore, the angle component is also provided with an extension bracket, which is fixed to the base of the longitudinal linear module, and the first motor and the transmission mechanism are respectively installed at both ends of the extension bracket.

[0011] Furthermore, at least one set of adjustment devices is installed on the frame, and at least one spray gun is installed at the actuator end of each set of adjustment devices, so as to spray the object placed on the rotating platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] ① Improved debugging and production efficiency: This invention, through the design of a beam-type frame and automated adjustment device, requires only one debugging session before each product is produced. The control module accurately records key parameters such as the position, angle, and oil output of the spray gun. When producing the same product subsequently, data can be quickly retrieved from the control module to automate the adjustment of spray gun parameters, significantly shortening debugging time, greatly improving production efficiency, and reducing production stoppages caused by frequent debugging.

[0014] ② Optimized spray gun adjustment function: The horizontal, vertical, and angle components in the adjustment device work together to achieve precise adjustment of the spray gun's horizontal, vertical position, and angle. The horizontal and vertical components can move the spray gun horizontally and vertically respectively, while the angle component can drive the spray gun to swing up and down within the 0-180° range, flexibly changing the spray angle to meet the needs of various complex spraying scenarios and improving the accuracy and flexibility of spray gun adjustment.

[0015] ③ Ensuring Production Safety: In the angle assembly, the first motor and transmission mechanism are respectively located at both ends of the longitudinal linear module base, and are transmitted through the first connecting rod, extending the distance between the first motor and the spray gun. Simultaneously, an explosion-proof servo motor is preferred as the power source, meeting explosion-proof safety requirements and keeping the motor away from flammable substances such as paint, effectively reducing safety risks caused by the motor and ensuring the safe conduct of the spraying operation.

[0016] ④ Expand the spray gun's range of motion: An extension bracket is installed and fixed to the base of the longitudinal linear module. On the one hand, this extends the horizontal movement distance of the spray gun without affecting the stability of the transverse linear module, solving the problem that an excessively long transverse linear module base leads to increased torque at the far end, affecting the stability of the spray gun. On the other hand, for adjustment devices in different positions, such as the first and fourth devices located on both sides of the rotating platform, the extension bracket can expand the lateral movement distance of the spray gun, enabling it to move accurately to the outer edge of the object for spraying, meeting the spraying needs of diverse products.

[0017] Therefore, this utility model, through the cooperation of an automated adjustment device and a control module, enables parameters to be stored after one-time debugging and automatically retrieved later, accurately adjusts the position and angle of the spray gun, extends the distance between the motor and the spray gun and uses an explosion-proof motor to ensure safety, and expands the range of motion with the help of an extension bracket, greatly improving debugging and production efficiency and meeting diverse spraying needs.

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1 to 6 In this embodiment of the present invention, a suspended automatic spray gun adjusting device includes a frame 10, a rotating platform 11 installed below the frame 10, and an adjusting device 20 installed on the frame 10 and extending towards the rotating platform 11. A spray gun 50 is installed at the drive end of the adjusting device 20. The spray gun 50 is used to perform spraying operations on the material on the rotating platform 11. The adjusting device 20 is used to adjust the operating parameters of the spray gun 50. The adjusting device 20 is provided with a control module, which is used to record the operating parameters of the spray gun 50 and control the adjusting device 20 to adjust the spray gun 50 according to the operating parameters.

[0030] Specifically, traditional spraying equipment typically requires manual adjustment of the operating parameters (such as position or angle) of the spray gun 50. When producing different products and needing to switch products for spraying, these operating parameters need to be readjusted, and each spray gun 50 needs to be re-calibrated and sampled, which is time-consuming and costly. Later, some automatic gun adjustment technologies emerged, but these solutions still have shortcomings. In particular, the drive motor is installed too close to the spray gun 50, which is not safe for spraying operations, and it cannot adjust the position of the entire spray gun 50 module over a wide range. Therefore, improvements are necessary.

[0031] This invention utilizes a beam-type frame 10 to mount the spray gun 50 above a rotating platform 11, and employs an adjustment device 20 to automatically adjust the position or angle of the spray gun 50, thereby improving debugging speed and optimizing production efficiency. Before producing each product, the entire equipment only needs to be debugged once, and the position or angle of the corresponding spray gun 50, as well as relevant parameters such as oil volume, are recorded by the control module. This eliminates the need for repeated debugging during subsequent production of the same product; the relevant parameters of the spray gun 50 can be automatically adjusted by directly retrieving the data from the control module, thus achieving rapid production, reducing debugging costs, and improving production efficiency.

[0032] Secondly, the control module can be configured using a Microcontroller Unit (MCU), a technology already in use. This involves installing corresponding intelligent control programs, such as drivers for linear modules, servo motors, or the spray gun 50, within the MCU to automate the control of the relevant functional components. Furthermore, a storage module is included in the control module to effectively store the operating parameters of the adjustment device 20 and the spray gun 50. This provides data support for subsequent adjustments to automated parameters during production, enabling more precise and intelligent control of the spraying equipment and improving its stability and reliability.

[0033] like Figures 2 to 4 As shown, preferably, the adjustment device 20 is further provided with a transverse component 30, a longitudinal component 33 and an angle component 40. The transverse component 30 is mounted on the frame 10, the longitudinal component 33 is mounted on the drive end of the transverse component 30, the angle component 40 is mounted on the drive end of the longitudinal component 33, and the spray gun 50 is mounted on the drive end of the angle component 40.

[0034] Specifically, in order to adjust the lateral and vertical positions of the spray gun 50, a lateral movement component 30 and a longitudinal movement component 33 are preferably provided. The lateral movement component 30 drives the longitudinal movement component 33, the angle component 40 and the spray gun 50 to move in the horizontal direction, the longitudinal movement component 33 drives the angle component 40 and the spray gun 50 to move in the vertical direction, and the angle component 40 drives the spray gun 50 to swing up and down. The angle adjustment is within the range of 0~180°, thereby changing the spray angle of the spray gun 50.

[0035] like Figures 2 to 3 As shown, preferably, the transverse component 30 is provided with a transverse support 31 and a transverse linear module 32. One end of the transverse support 31 is detachably fixed to the frame 10 by bolts, and the other end is used to install the transverse linear module 32. The longitudinal component 33 is provided with a longitudinal linear module 34. The slide portion of the longitudinal linear module 34 is fixedly connected to the slide portion of the transverse linear module 32. The angle component 40 is installed on the base of the longitudinal linear module 34.

[0036] Specifically, the transverse support 31 is preferably a long strip structure, used to mount the transverse linear module 32 onto the frame 10 and adjust its relative position to the frame 10 to accommodate the lateral movement range of the spray gun 50. The operation of the transverse linear module 32 causes its slide to drive the longitudinal linear module 34 to move laterally in the horizontal direction, thereby adjusting the lateral parameters of the spray gun 50. The slide of the longitudinal linear module 34 is fixed to the slide of the transverse linear module 32, causing the longitudinal linear module 34 to rotate, and its base to move vertically relative to its slide, thereby adjusting the vertical parameters of the spray gun 50.

[0037] like Figures 4 to 5 As shown, preferably, the angle assembly 40 is provided with a first motor 41, a first connecting rod 42 and a transmission mechanism 43. The first motor 41 and the transmission mechanism 43 are respectively installed at both ends of the base of the longitudinal linear module 34. One end of the first connecting rod 42 is connected to the output shaft of the first motor 41, and the other end is connected to the input shaft of the transmission mechanism 43. The spray gun 50 is installed on the output shaft of the transmission mechanism 43.

[0038] Specifically, in order to adjust the spray angle of the spray gun 50, a first motor 41 is preferably provided, so that the driving force of the first motor 41 is transmitted to the transmission mechanism 43 through the first connecting rod 42, and after the speed conversion and angle conversion of the transmission mechanism 43, the spray gun 50 is driven to rotate at the corresponding angle.

[0039] Secondly, the first motor 41 is preferably an explosion-proof servo motor, which allows for precise control of the rotation angle and meets explosion-proof safety requirements. To extend the distance between the first motor 41 and the spray gun 50, the first motor 41 and the transmission mechanism 43 are preferably positioned at opposite ends of the base of the longitudinal linear module 34, keeping them far apart, and then transmitted through the first connecting rod 42. The transmission mechanism 43 is preferably a gearbox, which uses gear meshing to achieve angle conversion and speed adjustment.

[0040] like Figures 5 to 6 As shown, preferably, the angle assembly 40 is further provided with an angle bracket 44, a timing belt, a first timing pulley 45 and a second timing pulley 46, wherein the angle bracket 44 is mounted on the transmission mechanism 43, the first timing pulley 45 and the second timing pulley 46 are rotatably connected to the angle bracket 44 respectively, the timing belt is sleeved on the first timing pulley 45 and the second timing pulley 46, the first timing pulley 45 is tractively connected to the output shaft of the transmission mechanism 43, and the spray gun 50 is mounted on the second timing pulley 46.

[0041] Specifically, in order to further optimize the angle adjustment structure of the spray gun 50, an angle bracket 44 is preferably provided and fixed to the transmission mechanism 43. Then, the output shaft of the transmission mechanism 43 is connected to the first synchronous pulley 45 to form a transmission connection, thereby driving the first synchronous pulley 45 to rotate. The synchronous drive of the synchronous belt drives the second synchronous pulley 46 to rotate, so that it drives the spray gun 50 to adjust the angle.

[0042] Secondly, the output shaft of the transmission mechanism 43 is a rotary output, so it can be connected to the first synchronous pulley 45 via key connection, flange connection, or other means. The rotation axes of the first synchronous pulley 45 and the second synchronous pulley 46 are parallel to each other and are rotatably connected to the angle bracket 44 via bearings or other connecting structures. The rotation angle of the spray gun 50 is in a preset ratio to the rotation angle of the output shaft of the transmission mechanism 43, and the ratio is inversely proportional to the number of teeth of the two synchronous pulleys.

[0043] like Figures 4 to 5 As shown, preferably, the angle component 40 is further provided with an extension bracket 47, which is fixed to the base of the longitudinal linear module 34, and the first motor 41 and the transmission mechanism 43 are respectively installed at both ends of the extension bracket 47.

[0044] Specifically, in order to extend the horizontal movement distance of the spray gun 50, an extension bracket 47 is preferably provided. The extension bracket 47 is installed on the base of the longitudinal linear module 34, away from the end of the transverse linear module 32. The extension bracket 47 is set parallel to the transverse linear module 32 and moves synchronously along the Y-axis direction with the drive of the transverse linear module 32, thereby expanding the movement range of the spray gun 50 in the Y-axis direction.

[0045] Secondly, if the base of the transverse linear module 32 is too long, the torque at its far end will increase, affecting the movement stability of the spray gun 50. Therefore, the lateral distance is extended by the extension bracket 47, rather than lengthening the base of the transverse linear module 32. Thus, the extension bracket 47 can be installed at the lower end of the base of the longitudinal linear module 34 to extend the lateral distance of the spray gun 50 without affecting the stability of the transverse linear module 32 itself.

[0046] like Figure 1 As shown, preferably, at least one set of adjustment devices 20 are installed on the frame 10, and at least one spray gun 50 is installed on the execution end of each set of adjustment devices 20, so as to spray the object placed on the rotating platform 11.

[0047] Specifically, a set of adjustment devices 20 can be installed on different parts of the frame 10. For example, the adjustment device 20 includes a first device 21, a second device 22, a third device 23, and a fourth device 24. The second device 22 and the third device 23 are installed on the frame 10 at positions directly above the rotating platform 11 to spray the inner ring of the object on the rotating platform 11. The first device 21 and the fourth device 24 are respectively installed on the frame 10 at positions on both sides of the rotating platform 11 to spray the outer ring of the object on the rotating platform 11.

[0048] Understandably, since the second device 22 and the third device 23 are located directly above the rotating platform 11, the extension bracket 47 is not required; the angle component 40 can be directly mounted on the base of the longitudinal linear module 34. However, since the first device 21 and the fourth device 24 are located on both sides of the rotating platform 11 and are relatively far from the object to be sprayed, the extension bracket 47 can be installed on the base of the longitudinal linear module 34. The angle component 40 is mounted on the extension bracket 47, thereby extending the lateral movement distance of the spray gun 50. This allows it to move a certain distance from both sides onto the rotating platform 11, ensuring that the spray gun 50 moves correctly to the outer edge of the object for spraying.

[0049] In order to make more precise and intelligent adjustments to the adjustment device 20 and the spray gun 50, it is preferable to set the transverse linear module 32 and the longitudinal linear module 34 as linear modules in the prior art, also known as linear modules, Cartesian coordinate robots, linear slides, etc., and in particular, the FTH50 track-embedded screw module can be used.

[0050] The spraying equipment of this invention is suitable for production lines requiring masking spraying. It can precisely spray specific areas of complex products and record data from multiple product production processes, such as the amount of oil sprayed and the position parameters of the spray gun. When switching products during production, it can automatically adjust to the correct position, reducing manual adjustment and sampling time.

[0051] This equipment is an automatic spray gun adjustment device. Its adjustment mechanism 20 has three degrees of freedom: the Y-axis (horizontal linear motion), the Z-axis (vertical linear motion), and the R-axis (rotational swing motion). All power actuators use explosion-proof servo motors, and the motors are designed to be positioned far from the spray gun 50. The Z-axis is the vertical axis for up-and-down movement, with a stroke of 400mm. The Y-axis is the horizontal axis for back-and-forth movement, with a stroke of 600mm. The R-axis is the vertical swing angle, adjustable from 0-180°, allowing for multi-angle, wide-range adjustment of the spray gun 50 to meet the spraying needs of various products.

[0052] In addition, the synchronous belt transmits power from the first synchronous pulley 45 to the second synchronous pulley 46, thereby driving the spray gun 50 to rotate and adjust the angle. This keeps the motor away from flammable substances such as paint, making it safer than traditional structures. The structure is lightweight and does not take up much space, and has a long stroke, which can meet the spraying production needs of products of various sizes. It is mainly used for spraying relatively complex products that require masking spraying, and the hanging structure facilitates loading onto the turntable, improving production efficiency.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
