[0028] This embodiment provides a conveying device, such as Figure 2 and Figure 3As shown, it includes a base 100, a conveying seat 200 and a bearing assembly 300, the conveying seat 200 is arranged on the top of the base 100, and a moving driving assembly 400 for driving the conveying seat 200 to move along the conveying direction is connected between the two; the bearing assembly 300 includes a support frame 310 fixedly arranged on the top bearing surface of the conveying seat 200, a bidirectional screw 320 rotatably connected to the support frame 310 and a first rotating driving member 330 connected to the bidirectional screw 320, the bidirectional screw 320 includes two screw segments with opposite rotation directions, and the two screw segments are both screwed with a first slider 340, the lower parts of the two first sliders 340 are both slidably connected to the conveying seat 200 along the axial direction of the bidirectional screw 320, and the upper parts are both connected to horizontal support rollers 350, and the end of the horizontal support roller 350 away from the first slider 340 is slidably connected to the support frame 310 along the axial direction of the bidirectional screw 320.

[0029] This embodiment also provides a painting device, such as Figure 1 and Figure 2 As shown, it includes a paint spraying component 500, a drying component 600 and the above-mentioned conveying device. The base 100 of the conveying device includes a loading position, a paint spraying position, a drying position and a unloading position in sequence along the conveying direction. The base 100 is provided with a paint spraying room 120 at the paint spraying position and a drying room 130 at the drying position. The paint spraying component 500 is arranged in the paint spraying room 120, and the drying component 600 is arranged in the drying room 130.

[0030] The present embodiment provides a conveying device and a paint spraying equipment, wherein the conveying device includes a base 100 as a bearing base, a bearing assembly 300 for bearing the workpiece to be painted, and a conveying seat 200 for driving the bearing assembly 300 to move along a conveying direction under the drive of a moving driving assembly 400; wherein the paint spraying equipment includes the above-mentioned conveying device for bearing and conveying the workpiece to be painted, a paint spraying assembly 500 for spraying paint on the workpiece to be painted located in a paint spraying room 120, and a drying assembly 600 for drying the painted workpiece located in a drying room 130.

[0031] Initially, the two horizontal support rollers 350 of the bearing assembly 300 are both extended horizontally and are arranged parallel to the axial direction of the bidirectional screw 320; when it is necessary to spray paint the part to be painted, such as the transmission shaft of an automobile, the mobile drive assembly 400 drives the conveying seat 200 to drive the bearing assembly 300 to move to the loading position, and firstly, the first rotating drive member 330 is started to drive the bidirectional screw 320 to rotate according to the diameter size of the transmission shaft. Since the external threads of the two screw sections of the bidirectional screw 320 have opposite rotation directions and the first slider 340 is slidably engaged with the conveying shaft, the two second A slider 340 can move toward or away from each other under the rotational drive of the corresponding screw segment and the sliding engagement of the conveying seat 200, and the spacing distance between the two horizontal support rollers 350 is adjusted accordingly; then the drive shaft is clamped between the two horizontal support rollers 350. Specifically, the outer cylindrical surface of the horizontal support roller 350 is divided into four arc surfaces by the horizontal plane and the vertical plane passing through the axis line. The two arc surfaces of the two horizontal support rollers 350 located at the upper part and facing each other serve as support surfaces, which are in contact with and tangent to the outer cylindrical surface of the drive shaft, thereby stably supporting the drive shaft on both sides.

[0032] Subsequently, the mobile drive component 400 drives the conveying seat 200 to drive the bearing component 300 and the transmission shaft it carries to the painting position. At this time, the transmission shaft is located in the paint spraying room 120, and the paint spraying component 500 is started to spray paint toward the transmission shaft; after the painting is completed, the mobile drive component 400 drives the conveying seat 200 to move to the drying position. At this time, the transmission shaft is located in the drying room 130, and the drying component 600 is started to dry the transmission shaft; subsequently, the mobile drive component 400 drives the conveying seat 200 to drive the bearing component 300 and the transmission shaft it carries that has been painted and dried to move to the unloading position, and the transmission shaft is removed, thereby completing the painting and drying of the conveying shaft.

[0033] Among them, when the conveying device provided by the present embodiment is used, on the one hand, the conveying seat 200 and the bearing assembly 300 installed on the top surface of the base 100 bear and support the workpiece to be sprayed with paint at the bottom, and the supporting surfaces of the two horizontal support rollers 350 can stably support the workpiece to be sprayed with paint on both sides, thereby improving the bearing stability of the conveying device on the workpiece to be sprayed with paint, and correspondingly ensuring the stable progress of painting and drying; on the other hand, the two horizontal support rollers 350 can adjust the spacing distance under the drive of the first rotating drive member 330 to adapt to the workpieces to be sprayed with paint of different diameters, thereby ensuring the stable support of the workpiece to be sprayed with paint. On the basis of this, the bearing range of the bearing assembly 300 is increased, and the applicable scope of the conveying device is correspondingly increased and its functionality is improved; on the other hand, the spacing adjustment of the two horizontal support rollers 350 is achieved through the cooperation of a single first rotating drive member 330, a single bidirectional screw 320 and two first sliders 340, and the first rotating drive member 330 can achieve a double moving stroke of the two horizontal support rollers 350 towards or away from each other through a smaller rotation stroke, the structure is simple and the drive adjustment efficiency is high, thereby improving the structural simplicity of the conveying device and improving the adjustment efficiency of its bearing assembly 300.

[0034] Specifically, the first rotation driving member 330 may be a motor.

[0035] In this embodiment, the conveying seat 200 is provided with a guide rod parallel to the bidirectional screw 320, and the two first sliders 340 are both provided with guide holes, and the guide rods are slidably inserted into the guide holes. This is one of the specific forms in which the lower part of the first slider 340 is slidably connected to the conveying seat 200, wherein the guide rod passes through the guide hole, and can limit the first slider 340 to rotate circumferentially around the bidirectional screw 320, so that when the bidirectional screw 320 rotates, the first slider 340 can slide and move along the axial direction of the guide rod, thereby realizing the interval adjustment of the two horizontal support rollers 350.

[0036] Optionally, in this embodiment, if Figure 3As shown, one of the two horizontal support rollers 350 in the bearing assembly 300 is connected to a second rotation driving member 360 for driving its rotation, and the other is rotationally connected to the support frame 310 and the corresponding first sliding block 340 . The workpiece to be painted is tangent to and supported on the supporting surfaces of two horizontal support rollers 350. In the paint spraying room 120, the paint spraying assembly 500 can spray paint on the outer surface of the workpiece to be painted that is located above the two supporting surfaces. After the painting of this area is completed, the second rotating drive member 360 can be started to drive the corresponding horizontal support roller 350 to rotate to drive the workpiece to be painted to rotate a certain angle. At the same time, the other horizontal support roller 350 rotates in the corresponding direction under the rotation of the workpiece to be painted. Then, there is rolling friction between the workpiece to be painted and the two horizontal support rollers 350, and the rotation resistance is smaller and the rotation smoothness is higher, so as to conveniently complete the rotation adjustment of the workpiece to be painted, so that the unpainted area of ​​the workpiece to be painted rotates upward to above the two supporting surfaces to continue to spray paint the area, thereby completing the painting treatment of the entire circumferential area of ​​the workpiece to be painted, and only the second rotating drive member 360 needs to be added to the bearing assembly 300, which has a simple structure, strong functionality, and a small driving load of the second rotating drive member 360, and can ensure the effectiveness of the rotation drive of the workpiece to be painted.

[0037] Of course, in addition to improving the convenience of painting, the second rotating drive member 360 can also be used to start the second rotating drive member 360 to drive the horizontal support roller 350 and then drive the paint spraying part to rotate in the drying chamber 130 to effectively dry the entire area.

[0038] Specifically, the second rotation driving member 360 may be a rotation motor, which is coaxially connected to the end of one of the horizontal support rollers 350 to achieve rotation driving of the horizontal support roller 350 .

[0039] Except for the above-mentioned case where only one of the horizontal support rollers 350 is connected to the second rotating drive member 360, in some other embodiments, the two horizontal support rollers 350 in the supporting assembly 300 may also be connected to the second rotating drive member 360. When in use, the two second rotating drive members 360 can be started, and the two rotating drive members drive the corresponding horizontal support rollers 350 to rotate in the same direction, thereby driving the workpiece to be painted to rotate a certain angle in the contact area between the two support surfaces and the workpiece to be painted, and then the two second rotating drive members 360 are closed.

[0040] In some other embodiments, in addition to driving the workpiece to be painted to rotate by the second rotating drive member 360 to achieve painting and drying treatment of the entire area thereof, manual rotation or other driving components that can drive the workpiece to be painted to rotate can also be used. For example, a support frame 310 is located on both sides of the axial direction of the workpiece to be painted, and a telescopic driving member that can be extended and retracted toward the workpiece to be painted is arranged. The driving end of the telescopic driving member is fixedly connected to a rotating driving member, and a clamp is connected to the driving end of the rotating driving member facing the workpiece to be painted. When there is no need to rotate the workpiece to be painted, the telescopic driving member drives the rotating driving member to be retracted to ensure the transportation of the workpiece to be painted by the carrying device; when it is necessary to rotate the workpiece to be painted, the telescopic driving member drives the rotating driving member to extend toward the workpiece to be painted until the clamps of the rotating driving members on both sides clamp the two ends of the workpiece to be painted, and then the rotating driving member drives the clamps to clamp the workpiece to be painted and rotate a certain angle, and then releases the workpiece to be painted and retracts to the initial position, thereby completing the rotation adjustment of the workpiece to be painted.

[0041] In this embodiment, Figure 3 As shown, the horizontal support roller 350 includes a rotating rod 351 and a plurality of support wheels 352. The plurality of support wheels 352 are coaxially rotatably sleeved on the rotating rod 351 and are arranged at intervals along the axial direction of the rotating rod 351. The plurality of support wheels 352 are rotatably sleeved on different axial positions of the rotating rod 351, so the plurality of support wheels 352 are fixed in the axial position of the rotating rod 351 and can rotate relative to the rotating rod 351 in the circumferential direction; the outer cylindrical surfaces of the plurality of support wheels 352 together constitute the outer cylindrical contour surface of the horizontal support roller 350. When in use, the outer cylindrical surfaces of the plurality of support wheels 352 simultaneously support different axial positions of the workpiece to be painted and the contact area between the two is small. Accordingly, the support stability of the workpiece to be painted is higher and the probability of the workpiece to be painted tilting is smaller. At the same time, the support wheels 352 drive the workpiece to be painted to rotate and adjust the painting area. The contact area between the support wheel 352 and the workpiece to be painted is small, and the adverse effect on the already painted area on the outer cylindrical surface of the workpiece to be painted is small during the relative rotation of the support wheel 352 and the workpiece to be painted, thereby ensuring the painting effect of the paint spraying equipment on the workpiece to be painted; in addition, the support wheel 352 is rotatably mounted on the rotating rod 351. On the basis of completing the support of the workpiece to be painted and ensuring the smooth rotation of the workpiece to be painted, the rotating rod 351 and the first slider 340 and the support frame 310 can be rotatably connected or fixedly connected, thereby reducing the restrictions on the installation form of the rotating rod 351 and improving the installation convenience of the rotating rod 351.

[0042] Specifically, Figure 3As shown, the support frame 310 may include four support ears 311, and every two of the four support ears 311 are arranged in a row and spaced apart along the conveying direction, and the two rows of support ears 311 are arranged in a width direction perpendicular to the conveying direction, wherein the two ends of the bidirectional screw 320 are rotationally connected with the two support ears 311 in the same row in a one-to-one manner, and a support rod 312 is connected between the two support ears 311 in the other row, and the axial directions of the support rod 312, the axial directions of the bidirectional screw 320 and the conveying direction are all consistent; the two first sliders 340 are screwed together with the two screw sections of the bidirectional screw 320 in a one-to-one manner through threaded holes, the first ends of the two horizontal support rollers 350 are connected with the two first sliders 340 in a one-to-one manner, and the second ends are connected with the second sliders 313, the two second sliders 313 are provided with through holes, and the support rod 312 is slidably inserted into the two through holes, thereby realizing the sliding connection between the second end of the horizontal support roller 350 and the support frame 310 along the axial direction of the bidirectional screw 320.

[0043] In this embodiment, the bearing assembly 300 may be multiple groups, such as Figure 3 As shown, two groups of bearing components 300 are arranged on the conveying seat 200 to simultaneously carry two parts to be painted for painting and drying, thereby improving the conveying efficiency of the conveying device and the painting efficiency of the paint spraying equipment; wherein, the adjacent sides of the two groups of bearing components 300 can share a supporting ear 311 to improve the compactness of the arrangement and the simplicity of the structure of the two groups of bearing components 300.

[0044] Specifically, in this embodiment, at least two guide grooves extending along the conveying direction and arranged along the width direction perpendicular to the conveying direction are provided on the top of the base 100, and at least two groups of rollers 210 are provided on the bottom of the conveying seat 200, and the at least two groups of rollers 210 are correspondingly and rollingly engaged with the at least two groups of guide grooves. The two groups of rollers 210 are arranged at intervals along the width direction perpendicular to the conveying direction, and the number of rollers 210 in each group of rollers 210 is at least two, and the multiple rollers 210 in the same group are arranged at intervals along the conveying direction, so that each roller 210 can stably support the conveying seat 200 to ensure its bearing stability; at the same time, during the process of the mobile driving assembly 400 driving the conveying seat 200 to move along the conveying direction, the engagement of the roller 210 with the guide groove can limit the moving direction of the support wheel 352, thereby improving the position accuracy of the conveying seat 200 moving along the conveying direction, and the roller 210 rolls forward in the guide groove, and the friction between the two relative movements is small, which correspondingly reduces the driving load of the mobile driving assembly 400.

[0045] Optionally, in this embodiment, if Figure 2 and Figure 3As shown, the mobile driving assembly 400 includes a third rotating driving member 410 provided on the conveying seat 200, a gear 420 fixedly provided at the driving end of the third rotating driving member 410, and a rack 430 fixedly provided on the top surface of the base 100 and extending along the conveying direction, and the gear 420 is meshed with the rack 430. When it is necessary to drive the conveying seat 200 to move, the third rotating driving member 410 is started, and the third rotating driving member 410 drives the gear 420 at its driving end to rotate, and the conveying seat 200 is driven to move along the conveying direction under the meshing action of the gear 420 and the rack 430.

[0046] Specifically, the third rotation driving member 410 may be a servo motor.

[0047] Preferably, if Figure 2 and Figure 3 As shown, a receiving hole 220 can be provided in the middle of the conveying seat 200, and the third rotating driving member 410 is located at the top of the conveying seat 200, and the gear 420 extends downward through the receiving hole 220. The roller 210 is supported between the conveying seat 200 and the base 100 so that there is a space between the two, and the rack 430 extends from the bottom of the conveying seat 200. The toothed section of the gear 420 extending downward from the receiving hole 220 meshes with the rack 430, thereby realizing the movement and driving of the conveying seat 200; wherein, the third rotating driving member 410 and the gear 420 are both installed above the conveying seat 200, and the installation is relatively convenient, and the conveying seat 200 can keep the rack 430 located below it covered during the movement, so that the conveying seat 200 can be driven to move. During the process of the delivery seat 200 moving into the paint spraying room 120 for painting, the delivery seat 200 can block the rack 430 located in the paint spraying room 120, thereby reducing the probability of the rack 430 in this area being painted, and correspondingly ensuring the meshing cooperation between the rack 430 and the gear 420; preferably, a protective cover can be provided above the third rotating drive member 410 and the gear 420 to reduce the probability of the third rotating drive member 410 and the gear 420 being painted, thereby improving the normal operation of the third rotating drive member 410 and the gear 420.

[0048] In this embodiment, Figure 2As shown, both ends of the top of the base 100 along the conveying direction are provided with a limit platform 110, and the limit platform 110 corresponds to the height of the conveying seat 200. One of the limit platforms 110 is located outside the first end of the rack 430, and the other limit platform 110 is located outside the second end of the rack 430. When the conveying platform moves along the rack 430 under the drive of the mobile drive assembly 400, when the conveying platform reaches the two end positions of the rack 430, it can abut against the limit platform 110 at the corresponding end to stop. The conveying stroke of the conveying platform is limited by the limit platform 110 to reduce the occurrence of the conveying platform being separated from the rack 430 or even the base 100, thereby ensuring the stable connection between the conveying platform and the base 100; wherein, the height of the limit platform 110 corresponds to the height of the conveying seat 200, and the limit platform 110 is stopped by abutting against the end of the conveying seat 200 to reduce the damage caused by the collision of the high limit platform 110 with the first rotating drive member 330 and the like.

[0049] Specifically, in this embodiment, Figure 1 and Figure 2 As shown, a loading enclosure 140 is provided on one side of the paint spraying room 120 facing the loading position, and the loading enclosure 140 encloses the loading position therein, and the loading enclosure 140 is higher than the bottom surface of the horizontal support roller 350 in the conveying device and lower than the axis of the horizontal support roller 350. When loading is required, the conveying seat 200 and the supporting assembly 300 thereon are located at the loading position. At this time, the loading enclosure 140 encloses the conveying seat 200 and the supporting assembly 300 therein, thereby providing them with a barrier and protection to reduce damage caused to them by external factors and harm caused by operator misoperation. In addition, the top of the loading enclosure 140 is higher than the bottom surface of the horizontal support roller 350 to ensure its effective barrier and protection. At the same time, the top of the loading enclosure 140 is lower than the axis of the horizontal support roller 350 to ensure that the supporting surface of the horizontal support roller 350 is located above the loading enclosure 140, so that a robot or the like can load the parts to be painted onto the supporting surface, thereby reducing the interference of the loading enclosure 140 with the loading and improving the convenience of loading.

[0050] Similarly, if Figure 1 and Figure 2As shown, a material unloading enclosure 150 may also be provided on the side of the drying chamber 130 facing the material unloading position, and the material unloading enclosure 150 encloses the material unloading position therein, and the material unloading enclosure 150 is higher than the bottom surface of the horizontal support roller 350 in the conveying device and lower than the axis of the horizontal support roller 350.
