Description

Technical Field

[0001] This utility model relates to the field of sprayer technology, and more specifically, to a vertical and horizontal four-axis servo sprayer. Background Technology

[0002] Sprayers are key auxiliary equipment for ensuring efficient and stable die-casting production. They are primarily used to uniformly spray the mold cavity, achieving core functions such as mold release agent application, mold cooling, and lubrication. Their working principle involves mixing mold release agent with compressed air in a specific ratio through high-precision nozzles to form atomized particles. Driven by a robotic arm or fixed track, these particles are directionally sprayed onto key areas such as the mold cavity and core along a preset trajectory. The spray volume, atomization particle size, and spray angle can be precisely adjusted according to the casting material (e.g., aluminum alloy, zinc alloy), mold structure, and production cycle, ensuring uniform adhesion of the mold release agent and reducing defects such as casting sticking and scratches. Modern sprayers are often equipped with intelligent control systems that can be linked with the die-casting machine. Through sensors, they monitor mold temperature in real time and automatically adjust spray parameters, significantly improving casting surface quality, extending mold life, and reducing manual labor intensity. They are an indispensable component of automated die-casting production lines.

[0003] Currently, most sprayers use linear dual-axis or single-axis linkage spraying methods. The two sets of spray panels cannot move independently, and their lateral movement is limited. When spraying release agent onto two sets of molds, it is difficult to achieve ideal spraying results, leading to uneven adhesion of the release agent and causing defects such as casting sticking and scratches. In severe cases, the machine must be stopped to clean the molds, reducing production efficiency. Therefore, we propose a vertical and horizontal four-axis servo sprayer. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a vertical and horizontal four-axis servo sprayer to solve the technical problems of unsatisfactory spraying effect and low efficiency of current sprayers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vertical and horizontal four-axis servo sprayer, including a Y-axis mechanism, a Z-axis mechanism disposed on the Y-axis mechanism, and a spraying mechanism disposed on the Z-axis mechanism. The Y-axis mechanism includes a mounting frame, a base plate disposed on the upper end of the mounting frame, a mounting box disposed on the upper end of the base plate, a first movable seat slidably mounted in the mounting box, and a second movable seat slidably mounted in the first movable seat. The Z-axis mechanism includes a first Z-axis box and a second Z-axis box fixedly disposed on the first movable seat and the second movable seat. The spraying mechanism includes a spraying pipe slidably mounted on the first Z-axis box and the second Z-axis box, a spraying panel disposed on the lower end of the spraying pipe, and a connecting pipe connected to the upper end of the spraying pipe.

[0006] Preferably, a first toothed plate is provided on the side end of the first movable seat, and a first equipment box is provided on the side end of the mounting box. A first motor is installed in the first equipment box, and the output shaft of the first motor extends into the mounting box to install a first gear. The first gear meshes with the teeth on the first toothed plate.

[0007] Preferably, a second toothed plate is provided on the side end of the second movable seat, a second equipment box is provided on the side end of the first movable seat, a second motor is provided inside the second equipment box, and the output shaft of the second motor extends into the first movable seat to install a second gear, which meshes with the second toothed plate.

[0008] Preferably, a first mounting plate is provided at the end of the first movable seat, and a second mounting plate is provided at the tail position on the second movable seat. The first Z-axis box and the second Z-axis box are respectively provided on the first movable seat and the second movable seat, and the first Z-axis box is connected to the first mounting plate by bolts, and the second Z-axis box is connected to the second mounting plate by bolts.

[0009] Preferably, the outer side of the spray pipe is provided with an outer shell, a limiting strip is provided on one side of the outer shell, a limiting groove is provided on the side of the outer shell away from the limiting strip, and symmetrically distributed positioning plates and limiting plates are provided at the front ends of the first Z-axis box and the second Z-axis box. A limiting track is provided on the side of the positioning plate, the limiting strip is located in the limiting track, and a limiting part is provided at the end of the limiting plate, the limiting part being inserted into the limiting groove.

[0010] Preferably, a third toothed plate is provided on the side of the outer casing, and a third motor and a fourth motor are respectively provided in the first Z-axis box and the second Z-axis box. A third gear is provided at the end of the main shaft of the third motor and the fourth motor, and the third gear meshes with the teeth on the third toothed plate.

[0011] Preferably, the upper end of the mounting box is provided with a feeding box, the front end of the feeding box is provided with a feeding pipe, the side end of the feeding box is provided with a conveying pipe, the end of the connecting pipe is provided with a connector, and the end of the conveying pipe is connected to the connecting pipe through the connector.

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

[0013] 1. This utility model uses independent Y-axis motors to drive the first and second moving seats, which can respectively drive two sets of Z-axis mechanisms and the spraying mechanism to move freely in the horizontal (Y-axis) direction, allowing for a wider range of spacing adjustment. The motors of the two sets of Z-axis mechanisms (the third and fourth motors) independently control the lifting and lowering of the spraying pipe (Z-axis), which can adapt to the height differences of different molds. This "dual Y-axis + dual Z-axis" four-axis independent control mode allows the two spraying panels to be precisely aligned for the cavity structure and size differences of the two molds. Through four-axis independent servo control and structural optimization, the core problems of uneven spraying and low efficiency of traditional sprayers are precisely solved.

[0014] 2. This utility model also ensures that there is no shaking when the spraying pipe moves in the Z-axis direction through the double constraint of the limiting strip and the positioning plate track, and the limiting part and the limiting groove, so as to avoid spraying deviation caused by vibration. The first moving seat and the mounting box, and the second moving seat and the first moving seat in the Y-axis direction are all designed with limiting sliding. With the rigid transmission of gear-tooth plate, the gap error is reduced and high precision can still be maintained after long-term use. The feeding system is connected to the conveying pipe through a sealed connector to reduce the risk of mold release agent leakage, ensure the uniformity of atomized particles, and further improve the spraying quality.

[0015] 3. This utility model also eliminates gap errors through gear and toothed plate transmission. Both the Y-axis and Z-axis adopt gear and toothed plate meshing transmission, combined with motor servo control, resulting in high positioning accuracy and a small error range. The double constraint prevents shaking. The spray pipe has a bidirectional constraint structure of "limiting strip + limiting track" and "limiting part + limiting groove", so there is no tilting or offset when the Z-axis moves. The limiting sliding design between the moving seat in the Y-axis direction and the mounting box and the moving seat further reduces vibration interference and ensures that the stable accuracy is maintained after long-term use.

Detailed Implementation

[0026] like Figures 1 to 9As shown, this utility model relates to a vertical and horizontal four-axis servo sprayer, including a Y-axis mechanism 100, a Z-axis mechanism 200 disposed on the Y-axis mechanism 100, and a spraying mechanism 300 disposed on the Z-axis mechanism 200. The Y-axis mechanism 100 includes a mounting frame 101, a base plate 103 disposed on the upper end of the mounting frame 101, a mounting box 102 disposed on the upper end of the base plate 103, a first movable seat 106 slidably mounted in the mounting box 102, and a second movable seat 107 slidably mounted in the first movable seat 106. The Z-axis mechanism 200 includes a first Z-axis box 201 and a second Z-axis box 202 fixedly disposed on the first movable seat 106 and the second movable seat 107. The spraying mechanism 300 includes a spraying pipe 301 slidably mounted on the first Z-axis box 201 and the second Z-axis box 202, a spraying panel 307 disposed on the lower end of the spraying pipe 301, and a connecting pipe 302 connected to the upper end of the spraying pipe 301. This invention solves the problems of "insufficient precision" and "low efficiency" of traditional sprayers when processing dual molds by using four-axis independent servo control, 300-degree collaborative operation of dual spraying mechanisms, and a stable structural design. Its core advantages are: it can meet the uniform spraying requirements of complex molds through precise four-axis linkage, and achieve efficient synchronous operation with independent control of dual mechanisms, providing a more reliable and efficient spraying solution for die-casting production lines, combining practicality and economy.

[0027] Specifically, a first toothed plate 1061 is provided on the side of the first movable seat 106, and a first equipment box 104 is provided on the side of the mounting box 102. A first motor 1041 is installed in the first equipment box 104, and the output shaft of the first motor 1041 extends into the mounting box 102 where a first gear is installed. The first gear meshes with the teeth on the first toothed plate 1061. When the first motor 1041 operates, the meshing transmission between the first gear and the first toothed plate 1061 can precisely control the first movable seat 106 to move outward within the mounting box 102, thereby driving the first Z-axis box 201 and the corresponding spraying mechanism 300 to achieve lateral movement in the Y-axis direction, meeting the spraying requirements of different lateral positions.

[0028] It is worth noting that a second toothed plate 1071 is provided on the side of the second movable seat 107, and a second equipment box 105 is provided on the side of the first movable seat 106. A second motor 1051 is installed inside the second equipment box 105. The output shaft of the second motor 1051 extends into the first movable seat 106 and is fitted with a second gear. The second gear meshes with the second toothed plate 1071. When the second motor 1051 operates, it can precisely drive the second movable seat 107 to move outward within the first movable seat 106 with the help of the gear and toothed plate. This, in turn, drives the second Z-axis box 202 and the corresponding spraying mechanism 300 to move independently in the Y-axis direction, realizing the individual or coordinated action of the two spraying mechanisms 300 in the Y-axis direction.

[0029] It is worth mentioning that a first mounting plate 1062 is provided at the end of the first movable seat 106, and a second mounting plate 1072 is provided at the tail position of the second movable seat 107. A first Z-axis box 201 and a second Z-axis box 202 are respectively provided on the first movable seat 106 and the second movable seat 107, and the first Z-axis box 201 is connected to the first mounting plate 1062 by bolts, and the second Z-axis box 202 is connected to the second mounting plate 1072 by bolts. The first Z-axis box 201 and the second Z-axis box 202 are respectively provided on the first movable seat 106 and the second movable seat 107, respectively. The first Z-axis box 201 changes position as the first movable seat 106 moves, and the second Z-axis box 202 changes position as the second movable seat 107 moves. This allows for convenient individual control of the two Z-axis, thereby facilitating individual spraying operations for the two spraying panels 307 and effectively improving spraying efficiency and spraying effect.

[0030] It is worth noting that the outer side of the spray pipe 301 is provided with a housing 3011. A limiting strip 305 is provided on one side of the housing 3011, and a limiting groove is provided on the side of the housing 3011 opposite to the limiting strip 305. The front ends of the first Z-axis box 201 and the second Z-axis box 202 are provided with symmetrically distributed positioning plates 2022 and limiting plates 203. A limiting track is provided on the side of the positioning plate 2022, and the limiting strip 305 is located in the limiting track. A limiting part 2031 is provided at the end of the limiting plate 203, and the limiting part 2031 is inserted into the limiting groove. The cooperation of the limiting strip 305 with the limiting track and the limiting part 2031 with the limiting groove can constrain the movement of the spray pipe 301 from both sides, effectively limiting the movement trajectory of the spray pipe 301, preventing it from deviating or shaking during its up and down movement, and ensuring the stability and accuracy of its up and down movement.

[0031] Furthermore, a third toothed plate 306 is provided on the side of the outer casing 3011. A third motor 2011 and a fourth motor 2021 are respectively provided in the first Z-axis box 201 and the second Z-axis box 202. A third gear is provided at the end of the main shaft of the third motor 2011 and the fourth motor 2021, and the third gear meshes with the teeth on the third toothed plate 306. The operation of the third motor 2011 and the fourth motor 2021 can drive the two spray pipes 301 to move up and down, so that the spray pipes 301 can move precisely in the Z-axis direction to meet the spraying requirements of different heights. At the same time, the two motors can work independently, which can realize the differentiated actions of the two spraying mechanisms 300 in the Z-axis direction.

[0032] Furthermore, a feed box 303 is provided at the upper end of the mounting box 102, a feed pipe 3031 is provided at the front end of the feed box 303, a conveying pipe 304 is installed at the side end of the feed box 303, and a connector 3021 is provided at the end of the connecting pipe 302. The end of the conveying pipe 304 is connected to the connecting pipe 302 through the connector 3021. This connection method ensures that the release agent can be smoothly conveyed from the feed box 303 to the spraying pipe 301, providing a continuous material supply for the spraying operation. At the same time, the connector 3021 facilitates the disassembly and assembly of the conveying pipe 304 and the connecting pipe 302, making it convenient for later maintenance and replacement.

[0033] Working Principle: This embodiment provides a vertical and horizontal four-axis servo sprayer. In use, firstly, release agent and other spraying materials are added to the feed box 303 through the feed pipe 3031. The materials enter the spraying pipe 301 through the conveying pipe 304, connector 3021, and connecting pipe 302, and are finally sprayed out through the spraying panel 307. When it is necessary to adjust the position of the spraying mechanism 300 in the Y-axis direction, the first motor 1041 operates, and its output shaft drives the first gear to rotate. Through the meshing transmission between the first gear and the first toothed plate 1061 on the side of the first moving seat 106, the first moving seat 106 is driven to slide within the mounting box 102, thereby driving the first Z-axis box 201 and the corresponding spraying mechanism 300 to move along the Y-axis direction. Simultaneously, the second motor 1051 operates, and its output shaft drives the second gear to rotate. Through the meshing transmission between the second gear and the second toothed plate 1071 on the side of the second moving seat 107, the second moving seat 107 is driven to slide within the first moving seat 106, thus driving the first Z-axis box 201 and the corresponding spraying mechanism 300 to move along the Y-axis direction. This drives the second Z-axis box 202 and the corresponding spraying mechanism 300 to move independently along the Y-axis, enabling individual or coordinated adjustment of the two spraying mechanisms 300 in the Y-axis direction. When it is necessary to adjust the position of the spraying mechanism 300 in the Z-axis direction, the third motor 2011 inside the first Z-axis box 201 operates, and the third gear at the end of its main shaft meshes with the third toothed plate 306 on the side of the outer shell 3011 of the spraying pipe 301, while simultaneously setting up the upper limit track on the limit bar 305 and the positioning plate 2022. With the cooperation of the limiting plate 203 end limiting part 2031 and the upper limiting groove of the outer shell 3011, the corresponding spraying pipe 301 and spraying panel 307 are driven to move stably along the Z-axis direction. Similarly, the fourth motor 2021 in the second Z-axis box 202 works to drive another set of spraying pipes 301 and spraying panels 307 to move independently along the Z-axis direction. Through four-axis servo control in the Y-axis and Z-axis directions, the two spraying panels 307 can achieve precise, efficient and uniform spraying of the mold.

[0034] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
