In some embodiments, as shown in fig. 1, the conveying device 1 for conveying the flower basket 2 comprises: a conveyor belt 10, a hold-down member 20 and a turnover mechanism 30. The conveyor belt 10 is for conveying a flower basket and has a carrying surface 11 for carrying the flower basket. For example, the elastic conveying belt 10 is sleeved outside the driving wheel and the driven wheel, the driving wheel can drive the part, located above the driving wheel, of the conveying belt 10 to move from the driving wheel to the driven wheel, and drive the part, located below the driving wheel, of the conveying belt 10 to move from the driven wheel to the driving wheel, the bearing surface 11 can be the top surface of the part, located above the driving wheel, of the conveying belt 10, and the basket 2 can be placed on the bearing surface 11 to enable the basket 2 to move linearly from the driving wheel to the driven wheel. The pressing member 20 abuts against the bearing surface 11 for pressing down a part of the conveyor belt to form the avoidance space 12, that is, the pressing member 20 recesses a part of the conveyor belt to form the avoidance space 12 by applying a downward pressure to the bearing surface 11.
The lower end of the turnover mechanism 30 continuously moves between a first position and a second position, and the second position is a position where the lower end of the turnover mechanism 30 is higher than the bearing surface by a predetermined distance, so that the flower basket output to the turnover mechanism 30 is lifted to a position where the flower basket is separated from the bearing surface 11, a sufficient space is provided for turning over the flower basket 2, and the possibility that the flower basket 2 collides with the conveyor belt 10 in the process of turning over the flower basket 2 is reduced. In order to more clearly illustrate the principle of the turnover mechanism 30 for turning over the flower basket, the following description will be made with reference to fig. 1 and 2 to illustrate the structure of the turnover mechanism 30 in the first position and the second position, and the relative positional relationship between the lower end of the turnover mechanism 30, the bearing surface 11 and the flower basket.
As shown in fig. 1, the first position is a position where the lower end of the turnover mechanism 30 is located in the avoidance space 12, so that the basket 2 is conveyed from the carrying surface 11 to the turnover mechanism 30, and illustratively, when the lower end of the turnover mechanism 30 is located in the first position, the lower end is located in the avoidance space 12, and the top surface of the lower end is not higher than the carrying surface 11, so that the basket 2 on the carrying surface 11 can be conveyed to the upper side of the lower end of the turnover mechanism 30, so that the basket 2 is conveyed from the carrying surface to the turnover mechanism 30. Optionally, when the flower basket 2 moves to the position above the lower end, the lower end of the turnover mechanism 30 moves upwards to lift the flower basket 2 to a position separated from the bearing surface 11, so that the flower basket 2 does not move along with the movement of the bearing surface 11; optionally, the conveying device 1 further includes a position sensor and a control element, when the position sensor senses that the flower basket 2 moves to the position above the lower end, the position sensor triggers the control element to send a stop signal to the conveyor belt, the conveyor belt 10 stops moving in response to the stop signal, after the flower basket 2 is turned over by the turning mechanism 30 and the turned flower basket is placed on the bearing surface 11 again, the turning mechanism 30 triggers the control element to send a restart signal to the conveyor belt, and the conveyor belt 10 starts to operate again in response to the restart signal, so as to convey the turned flower basket 2 to the next position.
As shown in fig. 2, when the lower end of the turnover mechanism 30 is located at the second position, the turnover mechanism 30 clamps and turns over the basket 2, so that the positions of the upper end and the lower end of the basket 2 are exchanged, thereby exchanging the positions of the upper surface and the lower surface of the silicon wafer stored in the basket 2.
The turnover mechanism 30 may be any structure capable of clamping and turning over the flower basket 2 when the lower end is located at the second position. Optionally, the turnover mechanism 30 further includes an upper end, and when the lower end of the turnover mechanism 30 is located at the second position, the lower end of the turnover mechanism 30 and the upper end of the turnover mechanism 30 are respectively abutted against the bottom surface and the top surface of the basket 2, so as to clamp the basket 2; after clamping the flower basket 2, the overturning mechanism 30 integrally rotates, so that the positions of the lower end and the upper end of the overturning mechanism 30 are exchanged, and the flower basket 2 is overturned; after the flower basket 2 is turned over, the lower end of the turning mechanism 30 returns to the first position, so that the turned flower basket 2 is placed on the bearing surface 11 again. Optionally, the lower end of the turnover mechanism 30 is provided with a clamping structure, and when the lower end moves to the second position, the clamping structure clamps the flower basket; after clamping the flower basket 2, the overturning mechanism 30 integrally overturns, and the lower end moves to the upper end of the overturning mechanism 30, so that the flower basket is overturned; after the flower basket 2 is turned over, the upper end of the turning mechanism 30 moves downwards to place the turned flower basket 2 on the bearing surface 11 again, and meanwhile, the clamping structure for clamping the flower basket 2 is released; after the flower basket 2 moves with the conveyor belt 10 and is separated from the turnover mechanism 30, the turnover mechanism 30 is turned over again so that the upper end moves to the lower end again, and then the lower end moves to the first position.
It should be noted that the lower end of the turnover mechanism 30 continuously moves between the first position and the second position, and it is understood that the lower end of the turnover mechanism 30 does not stop moving and always keeps in contact with the flower basket 2 during the movement between the first position and the second position, that is, during the lifting of the flower basket 2 at the lower end, the flower basket 2 does not need to be clamped by other structures, and the flower basket 2 is continuously lifted to the second position, and the flower basket 2 is separated from the lower end at the second position. Therefore, on the premise that an additional clamping structure is not needed, the flower basket 2 is lifted and clamped through the lower end, the structure of the turnover mechanism 30 is more compact, and the occupied space is smaller. Meanwhile, compared with the prior art that the flower basket is transmitted through the rollers and the lower end of the turnover mechanism is arranged between the adjacent rollers, the rollers are of the structure arranged at intervals, and the stability of the flower basket transmitted through the rollers is to be improved. Through conveyer belt 10 transmission basket of flowers, set up simultaneously down the piece 20 and form the dodging space that supplies tilting mechanism 30's lower extreme to get into on the continuous conveyer belt 10 of structure, make tilting mechanism 30's lower extreme lift simultaneously and press from both sides tight basket of flowers, under the prerequisite that reduces tilting mechanism 30's occupation space, still make basket of flowers 2's transmission more steady.
The embodiment of the utility model provides a transmission device for transmitting a flower basket, which comprises: the conveying belt is used for conveying the flower basket and is provided with a bearing surface used for bearing the flower basket, a lower pressing piece which is abutted against the bearing surface and is used for pressing part of the conveying belt downwards to form an avoiding space, and a turnover mechanism used for turning over the flower basket. The lower end of the turnover mechanism continuously moves between a first position and a second position, the first position is that the lower end of the turnover mechanism is located in the avoidance space, the second position is that the lower end of the turnover mechanism is higher than the bearing surface by a preset distance, and when the lower end of the turnover mechanism is located at the second position, the turnover mechanism clamps and turns over the flower basket. The flower basket is conveyed by the conveying belt with a continuous structure, so that the stability of conveying the flower basket is improved. Simultaneously, it forms the space of dodging to push down the conveyer belt that will have continuous structure through setting up down the piece, and tilting mechanism's lower extreme when first position department, this lower extreme is located dodges the space, and this lower extreme can be by first position continuous motion to the second position, can understand, tilting mechanism's lower extreme is at the in-process of motion between first position and second position, there is not the pause in the motion of this lower extreme, and keep the contact with the basket of flowers all the time, namely, at the in-process of this lower extreme lifting basket of flowers, need not other structures and press from both sides tight basket of flowers, and continue to lift the basket of flowers to the second position, and at this second position basket of flowers and this lower extreme separation. Therefore, on the premise of not additionally arranging a clamping structure, the lifting and clamping of the flower basket are simultaneously realized through the lower end, the structure of the turnover mechanism is more compact, and the occupied space is smaller.
In some embodiments, the conveyor belt 10, the lower member 20 and the turnover mechanism 30 of the conveying device 1 are suspended by hoisting means to a fixed member in the use environment, which may be, for example, a truss structure in a factory building.
In some embodiments, as shown in fig. 1, the transfer device 1 further comprises a frame 40. The conveyor belt 10 is movably coupled to the frame 40. illustratively, the conveyor belt 10 is disposed about a drive wheel and a driven wheel that are rotatably coupled to the frame 40 such that the conveyor belt 10 is movably coupled to the frame 40. The push-down member 20 and the turnover mechanism 30 are connected to the frame 40. The rack 40 is arranged to provide an installation space for the conveyor belt 10, the pressing piece 20 and the turnover mechanism 30, and meanwhile, the preset installation position of the rack 40 can also limit the relative positions of the conveyor belt 10, the pressing piece 20 and the turnover mechanism 30, so that the installation of the conveyor belt 10, the pressing piece 20 and the turnover mechanism 30 is facilitated.
In some embodiments, as shown in FIG. 3, canting mechanism 30 comprises: mounting plate 31, clamping jaw 32, upset driving piece 33. Perpendicular to the extension of the conveyor belt 10 in fig. 1, a mounting plate 31 is located on one side of the conveyor belt 10 for mounting a clamping jaw 32. The clamping jaw 32 has a plurality of, at least two clamping jaws are provided at both ends of the mounting plate 31 in the vertical direction, that is, the clamping jaws 32 are mounted at both upper and lower ends of the mounting plate 31. The number and form of the two ends of the jaws in the vertical direction of the mounting plate 31 may vary depending on the number of the jaws 32. For example, the number of the clamping jaws 32 is 2, and one clamping jaw 32 is arranged at each of the two ends of the mounting plate 31 in the vertical direction; for example, the number of the clamping jaws 32 is 3, 1 clamping jaw 32 can be arranged at one end of the mounting plate 31 in the vertical direction, and correspondingly, 2 clamping jaws 32 can be arranged at the other end of the mounting plate 31 in the vertical direction. The lower pressing member 20 is disposed corresponding to the position of each clamping jaw 32 at the lower end, so that each clamping jaw 32 can enter the avoidance space 12 at the first position. It should be noted that the vertical direction may be a direction substantially parallel to the gravity direction or the vertical direction, and it is understood that an included angle not greater than a preset angle is allowed to exist between a line connecting both ends of the mounting plate 31 where the clamping jaws are disposed and the gravity direction or the vertical direction due to a manufacturing error or a mounting error, and for example, the preset angle may be 3 degrees, and an included angle between a line connecting both ends of the mounting plate 31 where the clamping jaws are disposed and the gravity direction or the vertical direction is not greater than 3 degrees.
The clamping jaw 32 is slidably connected with the mounting plate 31, the clamping jaw 32 can be continuously lifted from the first position to the second position, namely, the clamping jaw 32 at the upper end and the clamping jaw 32 at the lower end can both slide in the vertical direction, and the clamping jaw 32 at the lower end can be continuously lifted from the first position to the second position. Optionally, during the process that the clamping jaw 32 at the lower end moves from the first position to the second position, the clamping jaw 32 at the upper end keeps stationary relative to the mounting plate 31 until the clamping jaw 32 at the lower end moves to the second position, that is, the turnover mechanism 30 only needs to control the movement state of the clamping jaw 32 at the lower end, and the control difficulty of the turnover mechanism 30 is reduced. Alternatively, after the turnover mechanism 30 is turned over, the distance between the clamping jaw 32 at the upper end and the clamping jaw 32 at the lower end in the vertical direction is increased, so that the possibility of movement interference between the clamping jaw 32 at the upper end and the flower basket is reduced, and the turnover mechanism 30 can turn over the flower basket with larger size. Meanwhile, in the process that the clamping jaw 32 at the lower end is lowered from the second position to the first position, the clamping jaw 32 at the upper end is raised, and in the process that the clamping jaw 32 at the lower end is raised from the first position to the second position, the clamping jaw 32 at the upper end is lowered, so that the speed of clamping the flower basket by the clamping jaw 32 is increased, and the time required by the turnover mechanism 30 for turning over the flower basket is reduced. Wherein, in the first position, the clamping jaw 32 at the lower end is located in the avoidance space 12; in the second position, the clamping jaw 32 at the lower end is higher than the bearing surface 11, and the clamping jaw 32 clamps the basket 2, that is, in a state where the clamping jaw 32 at the lower end is located at the second position, the clamping jaw 32 at the lower end and the clamping jaw 32 at the upper end abut against the bottom and the top of the basket 2, respectively, so as to clamp the basket 2 between the clamping jaw 32 at the lower end and the clamping jaw 32 at the upper end.
The turnover driving member 33 is connected to the frame 40 and fixedly connected to the mounting plate 31 to drive the mounting plate 31 to turn over so as to change positions of the at least two clamping jaws 32 in the vertical direction, that is, to change positions of the clamping jaw 32 located at the upper end and the clamping jaw located at the lower end by driving the mounting plate 31 to turn over, it can be understood that after the turnover driving member 33 drives the mounting plate 31 to turn over, the clamping jaw 32 located at the upper end of the mounting plate 31 moves to the lower end of the mounting plate 31, and the clamping jaw 32 located at the lower end of the mounting plate 31 moves to the upper end of the mounting plate 31. When the clamping jaw 32 at the lower end is at the second position, the overturning driving part 33 drives the mounting plate 31 and the clamping jaw 32 to overturn, so that the flower basket 2 clamped by the clamping jaw 32 is overturned together with the mounting plate 31, the upper end of the flower basket 2 is exchanged with the lower end of the flower basket 2, and the overturning of the flower basket 2 is realized.
In some embodiments, as shown in fig. 4, the tumble drive 33 includes: a rotating motor 331, a first bevel gear 332, and a second bevel gear 333. The housing of the rotary motor 331 is fixedly coupled to the frame 40, thereby fixedly coupling the rotary motor 331 to the frame 40. The length direction of the rotary motor 331 is substantially parallel to the extending direction of the conveyor belt 10 in fig. 1, and it can be understood that an angle not greater than a preset angle, for example, 2 degrees, between the direction of the maximum size of the rotary motor 331 and the extending direction of the conveyor belt 10 is allowed due to a manufacturing error or a mounting error, and an angle not greater than 2 degrees between the direction of the maximum size of the rotary motor 331 and the extending direction of the conveyor belt 10 is reduced, thereby reducing the size of the turnover mechanism 30 perpendicular to the extending direction of the conveyor belt 10. The first bevel gear 332 is fixedly connected with the output shaft of the rotating motor 331, the second bevel gear 333 is fixedly connected with the mounting plate 31 and is meshed with the first bevel gear 332, and the direction of power transmission of the rotating motor 331 is changed by arranging the meshed first bevel gear 332 and second bevel gear 333, so that the power of the rotating motor 331 can be transmitted along a folding line which is bent by 90 degrees, and the size of the turnover mechanism 30 perpendicular to the extension direction of the conveyor belt 10 is reduced on the premise that the rotating motor 331 can drive the mounting plate 31 to turn over. Meanwhile, the wheel diameter of the second bevel gear 333 is larger than the wheel diameter of the first bevel gear 332, that is, the number of teeth of the second bevel gear 333 is larger than the wheel diameter of the first bevel gear 332, and the transmission ratio between the second bevel gear 333 and the first bevel gear 332 is larger than 1, so that the driving capability of the rotating motor 331 can be increased through a speed reduction and torque increase effect while the power transmission direction is changed, and the turnover mechanism 30 can turn over a heavier basket 2.
Optionally, the turnover driving member 33 further includes a second-stage speed reducing structure, the second-stage speed reducing structure is disposed between the second bevel gear 333 and the mounting plate 31, and the driving capability of the rotating electrical machine 331 is further improved through a speed reducing and moment increasing effect of the second-stage speed reducing structure. For example, the two-stage reduction structure may be a planetary reduction train comprising a sun gear, planet gears and an outer ring gear. The sun gear is fixedly connected with the second bevel gear 333 through the transmission shaft, the outer gear ring is arranged around the outer side of the sun gear and fixedly connected with the mounting plate 31, the planet gear is located between the outer gear ring and the sun gear and is simultaneously meshed with the outer gear ring and the sun gear, and the planet speed reduction gear train is compact in structure and can reduce the size of the overturning driving part 33 while realizing the two-stage speed reduction of the overturning driving part 33.
In some embodiments, as shown in fig. 5, the turnover mechanism 30 further includes a linear driving member 34, the linear driving member 34 may be a linear air cylinder, for example, and the linear driving member 34 is fixedly connected to the clamping jaw 32, so as to drive the clamping jaw 32 to move up and down. Meanwhile, along the vertical direction, the stroke of the linear driving part 34 is not smaller than the distance between the first position and the second position, that is, the linear driving part 34 can drive the clamping jaw to continuously rise from the first position to the second position without arranging an additional driving structure to drive the clamping jaw, so that the structure of the turnover mechanism 30 is more compact, and the occupied space of the turnover mechanism 30 is reduced.
In some embodiments, as shown in fig. 6, the outer edge of the avoiding space 12 decreases in size along the direction from the bearing surface 11 to the lower pressing member 20, that is, the outer edge of one end of the avoiding space 12 close to the bearing surface 11 is large in size, and the outer edge of one end of the avoiding space 12 close to the lower pressing member 20 is small in size, so that the avoiding space 12 is formed to be large in top and small in bottom, thereby facilitating the lower end of the turnover mechanism 30 to enter the avoiding space.
In some embodiments, as shown in fig. 6, the lower pressing member 20 is rotatably connected to the frame 40, that is, the belt 10 is pressed down by the rotatable idler pulley, and the friction between the belt 10 and the lower pressing member 20 is rolling friction, so that the wear of the belt 10 is reduced, and the service life of the belt 10 is prolonged.
In some embodiments, as shown in fig. 6, the conveying device 1 further includes a support 50, the support 50 is connected to the frame 40 and abuts against a surface of the conveyor belt 10 opposite to the bearing surface 11, for example, the bearing surface 11 is an upper surface of a portion of the conveyor belt 10 for conveying the flower basket 2, and the surface opposite to the bearing surface of the conveyor belt 10 is a lower surface of the portion. The supporting member 50 is located on at least one side of the pressing member 20 along the extending direction of the conveyor belt 10, and the supporting force applied to the conveyor belt 10 by the supporting member 50 limits the influence range of the pressing force applied to the carrying surface 11 by the pressing member 20 in the extending direction of the conveyor belt 10 within a preset length, so as to limit the size of the avoidance space 12, and for example, the supporting member 50 is located on the left side of the pressing member 20, and the avoidance space 12 extends to the left along the extending direction of the conveyor belt 10 to the position where the supporting member 50 contacts the conveyor belt 10 without extending to the left. The size of the avoiding space in the extending direction of the conveying belt 10 is limited by the bearing piece 22, the influence of the avoiding space on the stability of the conveying of the flower basket 2 is reduced, and the stability of the conveying of the flower basket 2 by the conveying device 1 is further improved.
In some embodiments, as shown in fig. 6, the supporting members 50 are provided in plurality and located at both sides of the lower pressing member 20 along the extending direction of the conveyor belt 10, so that the avoiding space is limited between two supporting members 50 adjacent to the lower pressing member 20 in the extending direction of the conveyor belt 10, the influence of the avoiding space on the smoothness of the transmission of the flower basket 2 is further reduced, and the smoothness of the transmission of the flower basket 2 by the transmission device 1 is further improved. Optionally, the distance between the contact positions of the support 50 adjacent to the lower pressing member 20 and the conveyor belt 10 along the extending direction of the conveyor belt 10 is greater than the contact length of the lower pressing member 20 and the carrying surface 11, so as to form the escape space 12 with a large upper part and a small lower part.
In some embodiments, as shown in fig. 6, the support member 50 is rotatably connected to the frame 40, i.e., supports the conveyor belt 10 via an idler pulley, and the friction between the support member 50 and the conveyor belt 10 is rolling friction, thereby reducing wear of the support member 50 on the conveyor belt 10 and prolonging the service life of the conveyor belt 10.
In some embodiments, the inner surface of the conveyor belt 10 is provided with a toothed structure, and the outer surfaces of the driving, supporting and driven wheels that are in contact with the inner surface of the conveyor belt 10 are provided with external teeth that can mesh with the toothed structure. Immediately, the conveyor belt 10 is a toothed belt, the driving wheel drives the conveyor belt 10 to move through the supporting force between the external teeth and the toothed structure, and compared with a flat belt transmission process, the driving wheel drives the conveyor belt to move through friction force, the possibility of local sliding between the conveyor belt 10 and the driving wheel can be reduced, and the accuracy of belt transmission is improved. In some embodiments, as shown in fig. 1, the conveying device 1 further includes a guiding structure 60 fixedly connected to the frame 40, wherein the guiding structure 60 is disposed on two sides of the carrying surface 11 in the extending direction perpendicular to the conveyor belt 10, and is used for guiding the flower basket 2 to the middle of the carrying surface 11 in the extending direction perpendicular to the conveyor belt 10, and limiting the relative movement between the flower basket 2 and the carrying surface 11 in the extending direction perpendicular to the conveyor belt 10, so that the flower basket 2 can be more accurately conveyed to the turnover mechanism 30. In some embodiments, as shown in fig. 1, the transmission device 1 further comprises a pressing wheel 70, and the pressing wheel 70 abuts against the conveyor belt 10 to adjust the tightness of the conveyor belt 10, so as to reduce the possibility of breakage of the conveyor belt 10 due to excessive tension while reliably transmitting the flower basket 2.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
