Description

Technical Field

[0001] This utility model belongs to the technical field of spray coating equipment, specifically relating to an automatic gun holder. Background Technology

[0002] In electrostatic powder coating technology, to ensure the spraying effect and the health of operators, a robotic arm is usually used to drive the spray gun to automatically spray the workpiece. In order to spray the workpiece in all directions, a large number of spray gun heads need to be set on the gun holder. However, in order to ensure the accuracy of spraying, the existing gun holder and spray gun head are welded and fixed, which makes the adjustment flexibility of the spray gun head insufficient. When applying different spraying requirements for different workpieces, it is necessary to replace the entire gun holder and spray gun head to adapt to different usage requirements. The operation is very troublesome, the processing cost is high, and it is time-consuming and labor-intensive, resulting in low workpiece processing efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an automatic gun mount to address the aforementioned problems.

[0004] This utility model is achieved through the following technical solution: an automatic gun holder, including a base and a first rotating arm, a second rotating arm, and a mounting bracket for mounting spray guns connected sequentially upwards on the base. The base and the first rotating arm are axially connected, and a first drive motor is provided at the axial connection. A connecting component is provided between the first rotating arm and the second rotating arm. The connecting component is fixedly connected to the second rotating arm and axially connected to the upper end of the first rotating arm. A second drive motor is provided on one side of the connecting component. The front end of the second rotating arm is connected to the middle of the mounting component. Two spray guns are detachably connected to both ends of the mounting bracket. A transmission motor is provided at the rear end of the second rotating arm. The interior of the second rotating arm is hollow and a transmission belt is provided along its length. The two ends of the transmission belt are respectively fixedly connected to the middle of the mounting bracket and the output shaft of the transmission motor. The output shaft of the transmission motor can rotate when the power is off. A transmission reset component for resetting the initial transmission state is provided at one end of the second rotating arm near the transmission motor. The mounting bracket includes a bushing embedded in the end of the second rotating arm, a rotating shaft fixedly installed in the bushing, and sleeves detachably connected to both ends of the rotating shaft. An extension plate is provided on the sleeve, and the spray gun is detachably mounted on the extension plate.

[0005] Furthermore, the transmission reset component is an encoder.

[0006] Furthermore, the transmission reset component consists of a limiting baffle fixed on the output shaft of the transmission motor and a sensor fixed on the inner wall of the second rotating arm. The sensor is set at the initial position corresponding to the limiting baffle, and the limiting baffle is located on the inner side of the transmission belt.

[0007] Furthermore, the connecting assembly includes a sleeve clamp fixed to the end of the first rotating arm, an end sleeve fixedly sleeved to the end of the second rotating arm, and a connecting plate. The upper end of the connecting plate is fixed at a distance of one-quarter from the end sleeve from the end of the second rotating arm, and the lower end of the connecting plate is axially fixed to the sleeve clamp.

[0008] Furthermore, threaded holes and limiting grooves are provided at both ends of the rotating shaft. The threaded holes are located in the middle of the limiting grooves. A first fixing screw is provided on the sleeve. A limiting block is provided on the side of the sleeve with the protruding end of the first fixing screw. The limiting block engages with the limiting groove. The first fixing screw and the threaded hole are threaded together.

[0009] Furthermore, the second rotating arm end is provided with a mounting housing, the mounting housing includes two half-housings, each half-housing including a plug-in portion and an opening portion, and second fixing screws are provided on the outer walls on both sides of the second rotating arm. The plug-in portion is fixedly installed at the end of the second rotating arm by the second fixing screws, and the opening portions of the two half-housings are combined to form a tire-shaped end.

[0010] Furthermore, both the base and the first rotating arm are hollow inside.

[0011] Furthermore, a first perforated plate is fixed on the outer wall of the base, and a second perforated plate is connected to the connecting assembly. Two sets of pipe holes are symmetrically provided on the second perforated plate, and the two sets of pipe holes are respectively set to the spray guns at both ends of the rotating shaft.

[0012] This invention features a detachable spray gun mounted on a mounting frame, allowing for easy replacement to meet the coating needs of the workpiece. Since the initial angle of the spray gun may change during assembly and disassembly, a rotating shaft within the mounting frame is connected to a drive motor via a transmission belt. When the equipment is operating, the drive motor is energized and locked, as are the rotating shaft and transmission belt. The spraying operation of the spray gun at different positions and angles on the workpiece is adjusted by a first and second rotating arm. When the equipment stops operating, the drive motor is de-energized, and its output shaft can rotate, thus allowing for the application of the spray gun at different positions and angles on the workpiece. When the spray guns at both ends of the mounting bracket are disassembled or assembled, the resulting twisting and pulling forces can drive the rotating shaft, transmission belt, and output shaft of the transmission motor to move synchronously. After the replacement is completed and the equipment is restarted, when the transmission motor is powered on again, the output shaft of the transmission motor is reset to its initial position through the transmission reset component, and then the rotating shaft is reset to its initial state through the transmission belt. This utility model can take into account both the replacement and reset requirements of the spray guns. During replacement, the connecting parts are movable to avoid damage and misalignment at the connection due to external forces. When in use, it automatically resets and locks to ensure the spraying accuracy of the spray gun. Attached Figure Description

[0019] The present invention will be further illustrated below with reference to specific examples and accompanying drawings.

[0020] like Figures 1-4As shown, this utility model describes an automatic gun holder, including a base 1 and a first rotating arm 2, a second rotating arm 3, and a mounting bracket 5 for mounting spray guns 4, which are sequentially connected upwards on the base 1. The base 1 and the first rotating arm 2 are axially connected, and a first drive motor 11 is provided at the axial connection. A connecting assembly 6 is provided between the first rotating arm 2 and the second rotating arm 3. The connecting assembly 6 is fixedly connected to the second rotating arm 3 and axially connected to the first rotating arm 2. A second drive motor 21 is provided on one side of the connecting assembly 6. The front end of the second rotating arm 3 is connected to the middle of the mounting assembly. Two spray guns 4 are detachably connected to both ends of the mounting bracket 5. A transmission motor 31 is provided at the rear end of the second rotating arm 3. The second rotating arm 3 is hollow inside and has a transmission belt 32 along its length. The two ends of the transmission belt 32 are respectively fixedly connected to the middle of the mounting frame 5 and the output shaft 311 of the transmission motor 31. The output shaft 311 of the transmission motor 31 can rotate when the power is off. The second rotating arm 3 has a transmission reset component 33 for resetting the initial transmission state at one end near the transmission motor 31. The mounting frame 5 includes a bushing 51 embedded in the end of the second rotating arm 3, a rotating shaft 52 fixedly installed in the bushing 51, and sleeves 53 detachably connected to both ends of the rotating shaft 52. The sleeves 53 are provided with extension plates 531, and the spray gun 4 is detachably mounted on the extension plates 531.

[0021] This invention features a detachable spray gun 4 mounted on a mounting frame 5, allowing for easy replacement of the spray gun 4 to meet the coating requirements of the workpiece. Since the initial angle of the spray gun 4 may change during assembly and disassembly, a rotating shaft 52 in the mounting frame 5 is connected to a drive motor 31 via a transmission belt 32. When the equipment is operating, the drive motor 31 is energized and locked, and the rotating shaft 52 and transmission belt 32 are also locked. The spraying operation of the spray gun 4 at different positions and angles of the workpiece is adjusted by the first rotating arm 2 and the second rotating arm 3. When the equipment stops operating, the drive motor 31 is de-energized, and its output shaft 311 can rotate, thus allowing for adjustment of the spray gun 4 at different positions and angles of the workpiece. When the spray guns 4 at both ends of the frame 5 are disassembled and assembled, the resulting twisting and pulling forces can drive the rotating shaft 52, the transmission belt 32, and the output shaft 311 of the transmission motor 31 to move synchronously. After the replacement is completed and the equipment is restarted, when the transmission motor 31 is powered on again, the output shaft 311 of the transmission motor 31 is reset to the initial position through the transmission reset component 33, and then the rotating shaft 52 is reset to the initial state through the transmission belt 32. This utility model can take into account both the replacement and reset requirements of the spray gun 4. During replacement, the connecting parts are movable to avoid damage and misalignment at the connection due to external forces. When in use, it automatically resets and locks to ensure the spraying accuracy of the spray gun 4.

[0022] In some embodiments, the transmission reset component 33 can be implemented by an encoder (not shown in the figure), especially an absolute encoder. The encoder is installed on the output shaft 311 of the transmission motor 31, which can achieve positioning and keep the shaft position unique when energized. This allows for precise control of the transmission motor 31 to maintain the unique position of the rotating shaft 52 through the transmission belt 32 when energized, thus achieving an automatic reset effect.

[0023] In other embodiments, the transmission reset member 33 can be implemented by using a limiting baffle 331 fixed on the output shaft 311 of the transmission motor 31 and a sensor 332 fixed on the inner wall of the second rotating arm 3. The sensor 332 is set at the initial position corresponding to the limiting baffle 331, and the limiting baffle 331 is located relative to the inner side of the transmission belt 32 (see reference). Figure 4 In the power-off state, the output shaft 311 of the drive motor 31 can rotate synchronously with the movement of the rotating shaft 52, and the limiting baffle 331 swings with the rotation of the output shaft 311. Since the limiting baffle 331 is located on the inner side of the transmission belt 32, the swing amplitude of the limiting baffle 331 is limited by the transmission belt 32 located on its upper and lower sides, so the rotating shaft 52 can rotate freely within a certain angle range. When the drive motor 31 is powered on again, the output shaft 311 of the drive motor 31 determines the initial position by rotating and cooperating with the sensor 332 to sense the limiting baffle 331. When the sensor 332 senses the limiting baffle 331, the drive motor 31 locks the output shaft 311 so that the spray guns 4 installed at both ends of the rotating shaft 52 are reset at the angle and locked to the initial state.

[0024] like Figure 1 and Figure 2 As shown, the connecting component 6 in this embodiment of the present invention includes a sleeve 61 fixed to the end of the first rotating arm 2, an end sleeve 62 fixedly sleeved to the end of the second rotating arm 3, and a connecting plate 63. The upper end of the connecting plate 63 is fixed to the end sleeve 62 at a distance of one-quarter from the end of the second rotating arm 3. The lower end of the connecting plate 63 is axially fixed to the sleeve 61. By setting the sleeve 61, the end sleeve 62, and the connecting plate 63, the axial connection position between the first rotating arm 2 and the second rotating arm 3 is located on the outside of the second rotating arm 3, so as to facilitate the independent installation of the transmission motor 31 and the second drive motor 21, without causing positional conflict between them, and to rationalize the installation of the components.

[0025] like Figure 2 and Figure 4As shown, in this embodiment of the present invention, the two ends of the rotating shaft 52 are provided with threaded holes 521 and limiting grooves 522. The threaded holes 521 are located in the middle of the limiting grooves 522. A first fixing screw 532 is provided on the sleeve 53. A limiting block 533 is provided on the side of the sleeve 53 with the protruding end of the first fixing screw 532. The limiting block 533 is engaged with the limiting groove 522. The first fixing screw 532 and the threaded hole 521 are threadedly connected. The sleeve 53 and the rotating shaft 52 are connected by the first fixing screw 532, which restricts the axial displacement of the two. The limiting block 533 and the limiting groove 522 further restrict the axial rotation of the two, thereby enhancing the connection stability.

[0026] like Figure 2 As shown, in this embodiment of the present invention, the second rotating arm 3 is provided with a mounting housing at its end. The mounting housing includes two half-housings 34. Each half-housing 34 includes a plug-in portion 341 and an opening portion 342. Second fixing screws 35 are provided on the outer walls of both sides of the second rotating arm 3. The plug-in portion 341 is fixedly installed at the end of the second rotating arm 3 by the second fixing screws 35. The opening portions 342 of the two half-housings 34 are combined to form a tire-shaped end. During installation, the bushing 51, the rotating shaft 52 and one end of the transmission belt 32 are first installed and placed between the two half-housings 34. After the two half-housings 34 are combined, they are inserted into the second rotating arm 3 through the plug-in portion 341. Then, the two half-housings 34 are fixed into the second rotating arm 3 from both sides by the second fixing screws 35, so that the bushing 51 and the rotating shaft 52 are fixedly installed at one end of the second rotating arm 3.

[0027] In this embodiment of the utility model, both the base 1 and the first rotating arm 2 are hollow inside, which is used for wires to pass through and connect, so that all wires can be integrated under the base 1. The equipment wires are basically buried inside, ensuring the neatness and simplicity of the equipment, and also avoiding the wires from being easily tangled and not conducive to regular maintenance.

[0028] like Figure 1 As shown, in this embodiment of the present invention, a first perforated plate 12 is fixed on the outer wall of the base 1, and a second perforated plate 13 is connected to the connecting component 6. Two sets of pipe holes 131 are symmetrically arranged on the second perforated plate 13. The two sets of pipe holes 131 are respectively set to the spray guns 4 at both ends of the rotating shaft 52. The air pipe is guided to both sides of the second rotating arm 3 through the first perforated plate 12 and the second perforated plate 13, and then respectively set to correspond to the spray guns 4. The pipe routing is clear and easy to disassemble and assemble.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
