[0039] In the related art, the paint spraying method is mostly manual use of a spray gun to spray the surface to be painted, which has low work efficiency. At the same time, the paint contains many toxic volatile substances, and the workers are easy to inhale a large amount of harmful substances, which threatens the health of the workers. Some spraying devices need to manually clamp the workpiece, and can only spray one side of the workpiece, and cannot automatically turn to the other side for continuous spraying, which is extremely inconvenient to use and reduces the spraying efficiency. In view of the above problems, the present application provides a spraying device, which has the function of automatically clamping the workpiece and can automatically turn the workpiece, and can improve the spraying efficiency.

[0040] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0041] like Figs. 1-3 As shown, this application provides a spraying device, including a clamping mechanism 2, a flipping mechanism 9, and a painting mechanism 4; the clamping mechanism 2 includes a clamping drive motor 2-1, a threaded rod 2-3, and two opposing clamping connectors 8, each clamping connector 8 having rotatable jaws 6, the two jaws 6 being used to clamp workpieces, the two clamping connectors 8 being drively connected to the threaded rod 2-3, and the clamping drive motor 2-1 being used to drive the threaded rod 2-3 to rotate, so that the two clamping connectors 8 move closer or further apart; the flipping mechanism 9 includes a flipping drive motor 12, a drive shaft 1... 1 and a transmission mechanism, wherein the flip drive motor 12 is used to drive the transmission shaft 11 to rotate, and the transmission mechanism is connected between the gripper 6 and the transmission shaft 11. The transmission shaft 11 is used to drive the gripper 6 to flip through the transmission mechanism; the painting mechanism 4 includes a paint pump 4-1, a paint tank 4-2 and a nozzle 4-3. The paint pump 4-1 is fixed to the paint tank 4-2. The inlet end of the paint pump 4-1 is connected to the paint tank 4-2 through a first connecting pipe. The outlet end of the paint pump 4-2 is connected to the nozzle 4-3 through a second connecting pipe. The nozzle 4-3 is aligned with the middle of the two grippers 6.

[0042] The spraying device provided in this application has a clamping mechanism 2 that can automatically clamp the workpiece with two grippers 6, and a flipping mechanism 9 that can drive the two grippers 6 to flip. The painting mechanism 4 sprays paint on the surface of the workpiece during the workpiece flipping process. This can avoid the manual use of spray guns, reduce the harm of paint to the operator's body, and improve the painting efficiency.

[0043] In some embodiments, the spraying device further includes a frame and a moving mechanism 3. The frame includes a base 1 and two frames 7 mounted on both sides of the base 1. The two frames 7 are slidably mounted on the base 1 in a transverse direction. The moving mechanism 3 is located between the base 1 and the frames 7 and is used to drive the two frames 7 to move along the base 1.

[0044] Specifically, the base 1 includes a base plate 1-1, and four brakeable swivel casters 10 are fixed to the lower end of the base plate 1-1 via a support column 14, which facilitates the movement of the equipment and can brake to prevent the equipment from shaking and moving during processing. The two frames 7 can be gantry frames, and the two frames 7 are arranged side by side. Each frame 7 is slidably installed along the transverse direction of the base 1, and the aforementioned clamping mechanism 2 and tilting mechanism 9 are arranged between the two frames 7.

[0045] In some embodiments, the base 1 is equipped with a shock-absorbing spring to prevent the entire device from vibrating too frequently during operation, thus affecting the overall stability.

[0046] See also Fig. 2In some embodiments, the clamping drive motor 2-1 is a bidirectional motor, two threaded rods 2-3 are provided, the bidirectional motor is arranged at the middle part of the two threaded rods 2-3, the two output shafts of the bidirectional motor arranged back to back are connected to the two threaded rods 2-3 one by one, and the end of each threaded rod 2-3 away from the bidirectional motor is rotatably connected to the frame 7 through a bearing. When the clamping drive motor 2-1 operates, it can drive the two threaded rods 2-3 to rotate synchronously and reversely, thereby driving the two clamping connecting pieces 8 to approach or move away from each other, completing the reciprocating movement of clamping and loosening of the two claws. In this embodiment, the bidirectional motor is used to drive the two threaded rods 2-3 to rotate forward and backward, and the clamping or loosening is controlled through the threaded cooperation, so that the operation stability of the clamping mechanism 2 is better, and the control accuracy of clamping or loosening is improved.

[0047] In some embodiments, the spraying device further comprises a support frame 2-2, which is fixedly installed on the frame 7; the bidirectional motor is fixedly installed on the upper end face of the support frame 2-2, the clamping connecting piece 8 is connected to the threaded rod 2-3 through the drive rod 5, one end of the drive rod 5 is fixedly connected to the clamping connecting piece 8, and the other end is threadedly connected to the corresponding threaded rod 2-3; wherein the drive rod 5 is provided with a threaded hole, the threaded hole is coaxially arranged with the threaded rod 2-3, and the threaded rod 2-3 is arranged in the threaded hole and is threadedly connected with the threaded hole.

[0048] The support frame 2-2 comprises two vertical plates fixed to the frame 7 and a horizontal plate connected between the two vertical plates, and the bidirectional motor is fixedly installed at the middle part of the upper end face of the horizontal plate, and the end of each threaded rod 2-3 away from the clamping drive motor 2-1 is rotatably connected to the vertical plate of the support frame 2-2 through a bearing.

[0049] The extension direction of the drive rod 5 is perpendicular to the axial direction of the threaded rod 2-3, one end of the drive rod 5 is connected to the threaded rod 2-3 through the threaded hole, and the other end is fixed to the clamping connecting piece 8. When the threaded rod 2-3 rotates, the drive rod 5 can move in the axial direction of the threaded rod 2-3, thereby driving the clamping connecting piece 8 to move through the drive rod 5.

[0050] Since the workpiece to be painted has different shapes and structures, it is necessary to ensure that the device is clamped in the most secure position to prevent the workpiece from falling off. After the first step of painting after clamping the workpiece, the other plane needs to be painted, and the workpiece needs to be rotated to align the surface to be painted with the spray gun. In order to meet the above requirements, the present application designs a turnover mechanism 9.

[0051] Referring to Fig. 3In some embodiments, the overturning mechanism 9 comprises two transmission mechanisms, each of which comprises a driving sprocket 9-1, a driven sprocket 9-2 and a transmission chain; the driving sprocket 9-1 and the driven sprocket 9-2 of each transmission mechanism are connected by the transmission chain; the transmission shaft 11 passes through the two clamping connectors 8, and the two transmission mechanisms are arranged on the two sides of the two clamping connectors 8; wherein the overturning drive motor 12 is fixed to one of the clamping connectors 8, the output shaft of the overturning drive motor 12 is connected with the transmission shaft 11, the driving sprockets 9-1 of the two transmission mechanisms are connected by the transmission shaft 11 and are arranged at the two ends of the transmission shaft 11, and the transmission shaft 11 is used to drive the two driving sprockets 9-1 to rotate; the driven sprockets 9-2 of the two transmission mechanisms are rotatably connected to the side of the clamping connector 8 away from the threaded rod 2-3 and are fixedly connected with the clamping jaw 6 inside the clamping connector 8. After being arranged in this way, the overturning mechanism 9 can drive the two clamping jaws 6 to overturn on the outside of the two clamping connectors 8, without affecting the movement of the clamping jaws 6 in the clamping area; the chain transmission mechanism can ensure that the rotation angle of the two clamping jaws 6 is always the same, reduce the error of the rotation angle of the clamping jaws 6, and avoid that the error of the overturning angle of the two clamping jaws 6 causes scratches on the surface of the workpiece.

[0052] In the present embodiment, the transmission shaft 11 passes through the two clamping connectors 8, the driving sprockets 9-1, the driven sprockets 9-2 and the transmission chains of the two transmission mechanisms are located at the rear side of the clamping connectors 8, and the driving sprockets 9-1, the driven sprockets 9-2 and the transmission chains of the two transmission mechanisms at least partially overlap the clamping connectors 8 in the axial direction of the threaded rod 2-3. In this way, not only can the thickness of the device in the direction perpendicular to the threaded rod 2-3 be reduced, which facilitates the arrangement of the paint spraying mechanism 4 on the side of the clamping jaw 6, but also the structure in the middle area of the two clamping connectors 8 is reduced, so that an independent spraying space area can be formed between the two clamping connectors 8.

[0053] In some embodiments, the transmission shaft 11 comprises a shaft tube and a shaft sleeve, and the shaft tube and the shaft sleeve are coaxially arranged; the driving sprocket 9-1 of one of the transmission mechanisms is installed on the shaft tube of the transmission shaft 11, and the driving sprocket 9-1 of the other transmission mechanism is installed on the shaft sleeve of the transmission shaft 11; one end of the shaft tube passes through one of the clamping connectors 8 and is fixedly connected with the output shaft of the overturning drive motor through a first bearing; one end of the shaft sleeve passes through the other clamping connector 8 through a second bearing, and the other end of the shaft sleeve is slidably sleeved on the other end of the shaft tube. After being arranged in this way, the shaft tube can rotate relative to one of the clamping connectors 8, and the shaft sleeve can rotate relative to the other clamping connector 8, so that the shaft tube and the shaft sleeve can rotate without affecting the movement of the two clamping connectors 8 in the axial direction, that is, the shaft tube and the shaft sleeve can rotate synchronously when the two clamping connectors 8 move closer or farther in the axial direction, so that the workpiece can be clamped and overturned at the same time.

[0054] In this embodiment, the shaft sleeve and the shaft tube are connected by spline, so that the movement between the shaft tube and the shaft sleeve is limited in the axial direction, and the shaft tube and the shaft sleeve cannot rotate relative to each other in the circumferential direction, thereby ensuring that the movement of the two clamping connectors 8 is always in the axial direction of the threaded rod 2-3, further improving the movement accuracy of the two clamping connectors 8, avoiding the loosening of the workpiece when clamped due to movement errors of the two clamping connectors 8, or avoiding the relative displacement between the workpiece and the clamping jaw 6 when clamped, thereby reducing the uniformity of the paint on the surface of the workpiece.

[0055] Continuing to refer to Figs. 1-3 In some embodiments, the clamping connector 8 is an inverted "L" shaped bracket, and the clamping jaw 6 is installed at the lower end of the inverted "L" shaped bracket; the upper end of the inverted "L" shaped bracket is a transversely extending moving part, and the moving parts of the two inverted "L" shaped brackets are arranged opposite to each other; the first bearing is arranged on the moving part of one of the inverted "L" shaped brackets, and the second bearing is arranged on the moving part of the other inverted "L" shaped bracket; the lower end of the inverted "L" shaped bracket is a longitudinally extending clamping part, and the two clamping parts are arranged on both sides of the two moving parts in the transverse direction, and the clamping jaw 6 has a predetermined width in the clamping part, and when the two clamping jaws 6 are in contact or have a predetermined spacing, the two moving parts abut against each other. After being arranged in this way, the two moving parts can limit the two clamping jaws 6 in the transverse direction when they abut against each other, thereby controlling the clamping force of the two clamping jaws 6, so that the pressure of the clamping jaw 6 acting on the surface of the workpiece is accurately controllable.

[0056] In some embodiments, the moving part of one of the clamping connectors 8 is provided with a fixed support 12-1, and the overturning drive motor 12 is installed on the fixed support 12-1 and moves with the moving part of the clamping connector 8; the fixed support 12-1 includes a side plate opposite to the clamping connector 8 in the transverse direction, the tail end of the overturning drive motor 12 is fixed to the side plate, and the output shaft at the head end is coaxially fixedly connected with the transmission shaft 11 in the clamping connector 8. In this embodiment, the output shaft of the overturning drive motor 12 is fixedly connected with the shaft tube, one of the driving sprockets 9-1 is fixed to the shaft tube and is close to one side of the overturning drive motor 12 and is located outside the moving part close to the overturning drive motor 12, and the other driving sprocket 9-1 is fixed to the shaft sleeve and is located outside the moving part away from the overturning drive motor 12.

[0057] Referring to Fig. 1In some embodiments, the top of the moving part is fixed with a sliding block 8-1, the frame is provided with a through hole for accommodating the sliding block, the sliding block 9-1 is in a strip shape, the sliding block 8-1 is arranged in the through hole and is limited to slide in the through hole. Specifically, the cross section of the sliding block 8-1 is in a T shape, the shape of the through hole matches the cross section of the sliding block 8-1, so that the movement of the sliding block 8-1 is limited in the length direction of the sliding block 8-1. In this embodiment, the sliding block 8-1, the threaded rod 2-3 and the transmission shaft 11 are parallel to each other and are located at the three vertices of the virtual triangle. The stability feature of the triangle makes the moving part limited to move in the three parallel directions, further improving the movement stability of the clamping connector.

[0058] In this embodiment, the moving part is provided with a connecting part for connecting with the driving rod 5 and is provided with a shaft hole for penetrating the transmission shaft 11. The opening direction of the screw hole on the driving rod 5 and the shaft hole are parallel to each other. In some embodiments, the screw hole and the shaft hole have a predetermined spacing in the direction perpendicular to the threaded rod 2-3, or the screw hole and the shaft hole are distributed on both sides of the moving part in the direction perpendicular to the threaded rod 2-3. After being arranged in this way, the moving part is limited to move in the threaded rod 2-3 through the threaded hole, and at the same time, the moving part is limited to move in the transmission shaft 11 through the shaft hole. Since the threaded rod 2-3 and the transmission shaft 11 are parallel to each other, the moving part is limited to move in the direction of the threaded rod 2-3 and the transmission shaft 11 which are parallel to each other. This can improve the stability and accuracy of the movement of the moving part in the direction parallel to the threaded rod 2-3, further ensure the position accuracy and clamping stability of the clamping jaw 6 clamping the workpiece, and also make the clamping force of the two clamping jaws 6 acting on the workpiece controllable.

[0059] In some embodiments, the clamping part is in a plate shape, the two clamping parts are parallel to each other, and the lower end of the clamping part is provided with a mounting hole which is arranged on the center line of the moving part. In this way, when the two moving parts move close to each other, the clamping force applied to the two sides of the workpiece by the two clamping jaws 6 is equal, thereby improving the clamping stability. In some embodiments, the mounting hole is provided with a bearing, and the rotating shaft of the driven sprocket 9-2 on the outside of the clamping part is fixedly connected with the clamping jaw 6 after penetrating through the bearing.

[0060] In some embodiments, the upper end surface of the paint tank 4-2 is provided with a paint pouring port 4-21, and a plug is installed at the paint pouring port 4-21. The spraying device further comprises a baking lamp plate 13 which is fixed at the lower end of the upper end surface of the base 1 and is away from the paint spraying mechanism 4. After spraying is completed, the workpiece can be automatically moved to the baking lamp plate 13 for baking, which is convenient to use and improves the work efficiency.
