Description

Technical Field

[0001] This utility model relates to the field of spraying equipment, specifically a side spray turntable that can rotate back and forth for spraying. Background Technology

[0002] Existing spraying turntable equipment has a single rotation direction, resulting in poor spray uniformity. Furthermore, when spraying different products, different spraying worktables need to be replaced, but existing spraying worktables are generally fixed to the spraying turntable equipment with screws, making disassembly and replacement inconvenient.

[0003] Therefore, it is necessary to provide a side spraying turntable that can rotate back and forth for spraying to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a side spray turntable that can rotate back and forth for spraying.

[0005] This utility model provides a side spraying turntable that can rotate back and forth for spraying, including a rotating arm and an XY plane rotation drive device for driving the rotating arm to rotate. Both ends of the rotating arm are fixed with U-shaped seats. A mounting seat is rotatably connected to the inner side of the U-shaped seat. An XZ plane rotation drive device for driving the mounting seat to rotate is installed in the U-shaped seat. The spraying turntable is installed on the top of the mounting seat. A drive assembly for driving the spraying turntable to rotate is installed on the mounting seat. When the working surface of the spraying turntable is horizontal, the mounting seat is in the initial position. When the mounting seat rotates from the initial position by less than or equal to a set angle, the spraying turntable is fixedly connected to the mounting seat. When the mounting seat rotates by more than the set angle, the spraying turntable and the mounting seat are detachable.

[0006] Preferably, the XY plane rotation drive device includes a housing and a first drive motor. The first drive motor is installed inside the housing, and the output shaft end of the first drive motor passes through the top of the housing and is fixedly connected to the rotating arm.

[0007] The first drive motor drives the rotating arm to rotate, so that one of the spraying turntables faces the spraying robot, and then sprays the workpiece on the spraying worktable. The other spraying worktable can be loaded with workpieces to be sprayed. During the spraying process, loading and unloading are carried out simultaneously.

[0008] Preferably, the XZ-plane rotary drive device includes a second drive motor fixed inside the U-shaped base. A drive gear is fixed to the output shaft end of the second drive motor. Rotary shafts are fixed to both sides of the mounting base and are rotatably connected to the U-shaped base. A driven gear is fixed to the end of one of the rotating shafts. The drive gear and the driven gear are connected by a gear belt. After the second drive motor starts, its output shaft drives the drive gear to rotate. The drive gear is connected to the driven gear via a gear belt, thus driving the driven gear to rotate. The driven gear is fixed to the end of a rotating shaft on one side of the mounting base, and the rotating shafts on both sides of the mounting base are rotatably connected to the U-shaped base. Therefore, the rotation of the driven gear will cause the mounting base to rotate within the XZ-plane. This allows for further adjustment of the angle of the spraying worktable, enabling it to adapt to spraying surfaces of different shapes and angles.

[0009] Preferably, the spraying turntable includes a spraying worktable and a cylindrical protrusion fixed to the bottom of the spraying worktable. A rotating sleeve is rotatably connected to the outer side of the cylindrical protrusion. A notch is provided at the end of the cylindrical protrusion. The drive assembly includes a motor fixed on a mounting base. The output end of the motor is provided with a protrusion that mates with the notch. A positioning groove is provided on the side wall of the rotating sleeve. A locking assembly that mates with the positioning groove is installed on the mounting base. The locking assembly locks the rotating sleeve and the mounting base in place.

[0010] Preferably, an unlocking component that cooperates with the locking component is fixed on the inner side of the U-shaped seat.

[0011] Preferably, the locking assembly includes an ear plate fixed to the top of the mounting base, a locking rod slidably connected inside the ear plate, and the end of the locking rod engaging with a positioning groove. A baffle is fixed to the outside of the locking rod, and a return spring is provided on the outside of the locking rod between the baffle and the ear plate. An L-shaped plate is fixed to one end of the locking rod, and a drive rod is fixed to the end of the L-shaped plate.

[0012] The motor is fixed to the mounting base, and its output end rotates when the motor starts. The output end has a protrusion that mates with a notch at the end of a cylindrical protrusion on the bottom of the spraying turntable. This mating structure allows the motor's rotation to drive the spraying turntable to rotate. The rotation of the spraying turntable enables the spraying equipment to spray the workpiece at different angles, improving the uniformity and quality of the coating.

[0013] Preferably, the unlocking component includes a fixing block fixed inside the U-shaped seat, and the fixing block engages with the end of the drive rod.

[0014] Preferably, the mounting base is fixed with a protective cover to prevent accidental contact and locking of the component.

[0015] Preferably, the chassis is equipped with support bases at all four corners of its bottom to make the chassis more stable.

[0016] Preferably, the spraying turntable is provided with mounting holes to facilitate the installation of the workpiece to be sprayed.

[0017] Locked state: Under normal circumstances, the locking rod, under the action of the return spring, engages with the positioning groove on the side wall of the rotating sleeve to lock and fix the rotating sleeve and the mounting base.

[0018] Unlocking process: After the second drive motor rotates the mounting base to a position greater than the set angle, the end of the drive rod contacts the fixed block, causing the end of the locking rod to be pulled out of the positioning groove. This locks the rotating sleeve against the mounting base, allowing the spraying turntable to be removed. Different sizes of spraying turntables can then be used to meet the spraying needs of different types of workpieces.

[0019] Compared with related technologies, the present invention provides the following beneficial effects:

[0020] Improve spraying efficiency: Through the coordinated operation of the XY plane rotary drive device and the XZ plane rotary drive device, the spraying equipment can rotate at multiple angles and in multiple directions, enabling the spraying robot to quickly and accurately reach the spraying position and improve spraying efficiency.

[0021] Improve coating quality: The coating turntable itself can rotate, allowing the coating equipment to spray the workpiece at different angles, improving the uniformity and quality of the coating, and reducing coating dead corners and missed areas.

[0022] Easy to replace the spraying turntable: The spraying turntable can be easily removed and installed through the cooperation of locking and unlocking components, meeting the spraying needs of different types of workpieces and improving the versatility and flexibility of the equipment.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] Please refer to 1- Figure 4 A side-spraying turntable for spraying that can rotate back and forth is disclosed. The turntable mainly consists of a rotating arm 1 and an XY plane rotation drive device 2 for driving the rotating arm 1 to rotate. The rotating arm 1 is the core component, and both ends of it are firmly fixed with U-shaped seats 3. These two U-shaped seats 3 are symmetrically distributed, providing stable support for subsequent installation and rotation.

[0030] Inside each U-shaped base 3, a mounting base 4 is rotatably connected. To enable the mounting base 4 to rotate in the XZ plane, an XZ plane rotation drive device 5 is also installed inside the U-shaped base 3. Specifically, the XZ plane rotation drive device 5 includes a second drive motor 51 fixed inside the U-shaped base 3, with a drive gear 52 fixedly connected to the end of the output shaft of the second drive motor 51. Rotating shafts 41 are fixed on both sides of the mounting base 4, and these two rotating shafts 41 are rotatably connected to the U-shaped base 3, ensuring smooth rotation of the mounting base 4. A driven gear 53 is fixed to the end of one of the rotating shafts 41, and the drive gear 52 and the driven gear 53 are connected by a gear belt 54. When the second drive motor 51 starts, its output shaft drives the drive gear 52 to rotate, which in turn drives the driven gear 53 to rotate via the gear belt 54, ultimately causing the mounting base 4 to rotate in the XZ plane to adapt to sprayed surfaces of different shapes and angles.

[0031] A spraying turntable 6 is mounted on top of the mounting base 4; this is a key component for placing the workpiece to be sprayed. Simultaneously, a drive assembly 7 for rotating the spraying turntable 6 is also mounted on the mounting base 4. The spraying turntable 6 specifically includes a spraying worktable 61 and a cylindrical protrusion 62 fixed to the bottom of the spraying worktable 61. A rotating sleeve 63 is rotatably connected to the outer side of the cylindrical protrusion 62. The end of the cylindrical protrusion 62 has a notch 621, while the drive assembly 7 includes a motor 71 fixed to the mounting base 4. The output end of the motor 71 has a protrusion that mates with the notch 621. When the motor 71 starts, its output end rotates, and through the engagement of the protrusion and the notch 621, it drives the spraying turntable 6 to rotate, thereby achieving multi-angle spraying.

[0032] To ensure the stability of the spraying turntable 6 during rotation, the side wall of the rotating sleeve 63 is provided with a positioning groove 631, and a locking assembly 8 that cooperates with the positioning groove 631 is installed on the mounting base 4. The locking assembly 8 includes an ear plate 81 fixed to the top of the mounting base 4, and a locking rod 82 is slidably connected inside the ear plate 81. The end of the locking rod 82 cooperates with the positioning groove 631 to achieve locking and fixing of the rotating sleeve 63 and the mounting base 4. A baffle 83 is fixed to the outside of the locking rod 82, and a return spring 84 is provided on the outside of the locking rod 82 between the baffle 83 and the ear plate 81 to ensure that the locking rod 82 is in the locked position under normal conditions. An L-shaped plate 85 is also fixed to one end of the locking rod 82, and a drive rod 86 is fixed to the end of the L-shaped plate 85 for subsequent unlocking operations.

[0033] In order to facilitate the replacement of the spraying turntable 6, when the working surface of the spraying turntable 6 is horizontal, the mounting base 4 is in the initial position. When the mounting base 4 rotates from the initial position to less than or equal to the set angle, the spraying worktable 61 and the mounting base 4 are fixedly connected. When the mounting base 4 rotates to more than the set angle, the spraying worktable 61 and the mounting base 4 are in a detachable state.

[0034] Specifically, an unlocking component 9, which cooperates with the locking component 8, is also fixed inside the U-shaped base 3. The unlocking component 9 includes a fixing block 91 fixed inside the U-shaped base 3. When the mounting base 4 rotates to an angle greater than the set angle, the drive rod 86 rotates with the mounting base 4, and the end of the drive rod 86 presses against the fixing block 91 fixed inside the U-shaped base 3. The fixing block 91 can push the drive rod 86 to move, thereby causing the locking rod 82 to overcome the elastic force of the return spring 84, so that the end of the locking rod 82 is pulled out from the positioning groove 631, and the rotating sleeve 63 is released from the locking state with the mounting base 4, so that the spraying turntable 6 can be easily removed for replacement.

[0035] It should be noted that the set angle for the rotation of the mounting base 4 is, for example, 90°. When the mounting base 4 rotates within 90°, it may still be within the spraying working range. When the mounting base 4 rotates more than 90°, it generally exceeds the rotation angle required for spraying. That is, when the side spray turntable is in operation, the locking rod 82 may not reach the unlocked state, and the rotating sleeve 63 and the mounting base 4 may not be disconnected.

[0036] In addition, a protective cover 10 is fixed on the mounting base 4 to prevent accidental locking of component 8. Support bases 211 are installed at each of the four corners of the bottom of the chassis 21 to ensure the stability of the entire turntable. The spraying turntable 6 is also equipped with mounting holes 64 for easy installation of workpieces to be sprayed.

[0037] Under normal operating conditions, the locking lever 82, under the action of the return spring 84, tightly engages with the positioning groove 631 on the side wall of the rotating sleeve 63, firmly locking and fixing the rotating sleeve 63 and the mounting base 4 to ensure the stability of the spraying process. When it is necessary to replace the spraying turntable 6, simply rotate the mounting base 4 to a greater than the set angle by driving the second drive motor 51, and the end of the drive lever 86 contacts the fixing block 91 to achieve the unlocking operation, thereby allowing the replacement of spraying turntables 6 of different sizes to meet the spraying needs of different types of workpieces.

[0038] Working principle:

[0039] Overall rotation drive: The XY plane rotation drive device 2 drives the rotating arm 1 to rotate in the XY plane, which serves as the basis for the movement of the entire turntable and provides position adjustment for subsequent movements in other directions. This allows the turntable to change its overall angle within the plane range to adapt to different spraying scenarios and workpiece placement positions.

[0040] XZ Plane Rotary Drive: When it is necessary to spray the workpiece at different angles within the XZ plane, the XZ plane rotary drive device 5 comes into play. The second drive motor 51, fixed inside the U-shaped base 3, starts, and its output shaft drives the drive gear 52 to rotate. The drive gear 52 is connected to the driven gear 53 via a gear belt 54, which in turn drives the rotating shafts 41 on both sides of the mounting base 4 to rotate. Since the rotating shafts 41 are rotatably connected to the U-shaped base 3, the mounting base 4 can rotate within the XZ plane, thereby allowing the spraying turntable 6 mounted on top of the mounting base 4 to be adjusted to different tilt angles to conform to spraying surfaces of different shapes and angles, achieving diverse spraying needs.

[0041] Rotation drive of the spraying turntable: The drive assembly 7 on the mounting base 4 is responsible for driving the spraying turntable 6 to rotate. After the motor 71 is started, its output end has a protrusion that cooperates with the notch 621 of the cylindrical protrusion 62 of the spraying turntable 6. Through the interaction between the protrusion and the notch 621, the spraying worktable 61 and the cylindrical protrusion 62 of the spraying turntable 6 are driven to rotate together, so that the workpiece to be sprayed placed on the spraying turntable 6 can rotate at multiple angles to achieve all-round spraying coverage.

[0042] Ensuring Rotational Stability of the Spraying Turntable: The locking assembly 8 plays a crucial role in ensuring the stability of the spraying turntable 6 during rotation. Under normal operating conditions, the locking rod 82, under the action of the return spring 84, has its end tightly engaged with the positioning groove 631 on the side wall of the rotating sleeve 63, firmly locking and fixing the rotating sleeve 63 and the mounting base 4. At this time, the spraying turntable 6 will not wobble or shift during rotation, ensuring the accuracy and quality of the spraying.

[0043] Convenient replacement mechanism for the spraying turntable: When the spraying turntable 6 needs to be replaced to adapt to the spraying requirements of different types of workpieces, the unlocking component 9 starts to work. As the second drive motor 51 drives the mounting base 4 to rotate to an angle greater than the set angle, the drive rod 86 rotates with the mounting base 4, and the end of the drive rod 86 presses against the fixing block 91 fixed inside the U-shaped base 3. The fixing block 91 pushes the drive rod 86 to move, thereby causing the locking rod 82 to overcome the elastic force of the return spring 84, causing the end of the locking rod 82 to be pulled out of the positioning groove 631, releasing the locking state between the rotating sleeve 63 and the mounting base 4. In this way, the spraying turntable 6 can be easily removed for replacement, meeting diverse spraying needs.
