In the preparation process of the battery piece, after the battery piece is suede/alkali polished, chemical residues on the surface of the battery piece are required to be cleaned through a water tank so as to ensure the product yield. In the cleaning process, the battery piece is arranged in the flower basket and is usually conveyed by a belt and is clamped and sucked into the main machine table by a manipulator, and the flower basket is in a vertical state on the belt, and the main machine table is in a groove structure, so that the flower basket needs to be overturned by the overturning table. In the related art, the belt is driven by the forward and reverse rotation servo motor, and is fixed on the overturning table top through the belt, so that the overturning table top and the flower basket shake in the stroke due to the elastic limitation of the belt and the instability of the transmission of the belt in the overturning process, and the battery piece is easy to be tooth-removed.

The present disclosure provides a conveying mechanism, and fig. 1 is a schematic front view of a conveying mechanism in an exemplary embodiment of the present disclosure, and as shown in fig. 1, the conveying mechanism 1 includes a flipping assembly 11 and a driving assembly 12. The turnover assembly 11 comprises a bracket 112 and a turntable body 111 rotatably connected with the bracket 112, wherein the turntable body 111 comprises a basket bearing surface 1111. The driving assembly 12 includes a driving motor 123, a driving gear 121 and a driven gear 122, and the driving gear 121 is connected to an output end of the driving motor 123. The driven gear 122 is assembled to the turntable body 111, and is engaged with the driving gear 121.

Because the driving component 12 comprises the driving gear 121 and the driven gear 122, the driven gear 122 is assembled on the rotating body, the driving of the rotating body can be realized through the engagement of the driving gear 121 and the driven gear 122, which are connected with the output shaft of the driving motor 123, the transmission is stable, and the problems that the basket falls off and fragments of battery pieces are caused in the overturning motion process due to the transmission of other modes such as a belt are avoided. In the transmission formed by meshing the driving gear 121 and the driven gear 122, the output rotation speed of the driving motor 123 can be controlled by analyzing the stress of the turntable main body 111, so that the driven gear 122 obtains stable rotation speed in the meshing with the driving gear 121, and the impact shake in the starting and transmission process of the movement is avoided.

The turning angle of the turntable main body 111 may be set according to the posture of the basket on the basket supporting surface 1111 and the posture required for entering the washing machine main body. In some embodiments, the basket may be vertically disposed on the basket supporting surface 1111, and the turn angle of the turntable body 111 may be 90 ° in order to facilitate the placement of the groove-type structure of the washing body table.

In some embodiments, one of the driving gear 121 and the driven gear 122 may be an external gear, and the other may be an internal gear. The transmission mechanism 1 can be compact in structure, space occupation and weight are reduced, and meshing stability, reliability and load capacity can be improved through the cooperation of the inner gear and the outer gear. For example, the driving gear 121 is an external gear, and the driven gear 122 is an internal gear. Alternatively, the driving gear 121 is an internal gear, and the driven gear 122 is an external gear.

In some embodiments, the driving gear 121 may be a circular external gear and the driven gear 122 may be a circular arc internal gear. The circular external gear is connected with the output end of the motor to drive the circular external gear to rotate, and the circular external gear is embedded into an arc-shaped space formed by the arc-shaped internal gear and meshed with the arc-shaped internal gear to form transmission. The motor output end rotates forward to drive the driven gear 122 and the turntable main body 111 to turn over, and the motor output end rotates backward to drive the driven gear 122 and the reversing main body to reset.

The base radii of the driving gear 121 and the driven gear 122 may be different, so that the number of teeth of the driven gear 122 meshed with the driving gear 121 is increased by the difference of the base radii, the contact area is further increased, the transmission stability is improved, and the risk of abnormal overturning caused by breakage of a certain tooth is reduced.

The central angle formed by the circular arc-shaped structure of the driven gear 122 may be determined according to the base radius of the driven gear 122. When the base radius of the driven gear 122 is equal to the base radius of the driving gear 121, the central angle of the circular arc structure of the driven gear 122 may be greater than or equal to 90 ° so that the turntable body 111 can obtain a 90 ° turning angle. When the base radius of the driven gear 122 is greater than that of the driving gear 121, the central angle of the circular arc structure of the driven gear 122 may be smaller than 90 degrees, that is, the turntable body 111 may obtain a 90 ° turning angle.

When the driving gear 121 is a circular arc internal gear and the driven gear 122 is a circular external gear, the radius of the base circle of the driving gear 121 may be larger than the radius of the base circle of the driven gear 122, and at this time, the central angle of the circular arc structure of the driving gear 121 may be smaller than 90 degrees, so that the turntable main body 111 may obtain a 90 ° turning angle.

In the above embodiment, the support 112 is rotatably connected to the middle area of the turntable body 111, so that the structural stability of the turntable body 111 during the overturning process is increased by rotationally connecting the support 112 to the middle area of the turntable body 111, thereby improving the reliability of the reverse-forward overturning motion. For example, the driven gear 122 is fixed to a bottom middle region of the turntable body 111, and the bracket 112 is located at the bottom of the turntable body 111 and is rotatably connected to a base structure of the driven gear 122. Alternatively, the bracket 112 is located at the bottom of the turntable body 111 and is directly rotatably connected to the turntable body 111.

In some embodiments, the turntable body 111 is provided with a clamping mechanism 13, the clamping mechanism 13 including an abutment 131 and a clamping cylinder 132, the abutment 131 and the clamping cylinder 132 being provided at both ends of the turntable body 111. When the flower basket is fed, the abutting piece 131 of the clamping structure and the abutting structure of the clamping cylinder 132 are positioned at two ends of the rotary table main body 111, so that structural interference on the flower basket feeding is avoided. Before the basket is turned over, the pushing structure of the clamping cylinder 132 pushes against the basket to avoid dropping and moving the basket.

In the above embodiment, the pushing structure 1321 of the clamping cylinder 132 may be provided with the clamping protrusion 1322, the side wall of the flower basket may be provided with a through hole corresponding to the position of the clamping protrusion 1322, and the depth of the clamping protrusion 1322 embedded into the through hole is equal to the thickness of the side wall, so that the embedded degree of the flower basket and the clamping mechanism 13 is improved, and fragments and broken edges caused by the falling or displacement of the flower basket due to insufficient clamping degree are avoided. The pushing structure 1321 may be a pushing plate. The grip protrusions 1322 may be one or more protrusions provided on the pushing plate, for example, three grip protrusions 1322 are provided on three vertices of a triangle, which can further improve grip stability.

In some embodiments, as shown in fig. 2, the turntable body 111 includes a bearing space 1112 on a side of the basket bearing surface 1111, the driven gear 122 is assembled in an assembling space 1113 on a side of the turntable body 111 opposite to the basket bearing surface 1111, and the turntable body 111 separates the bearing space 1112 and the assembling space 1113 into independent spaces that are not communicated with each other. That is, the basket supporting surface 1111 of the turntable main body 111 is an integral continuous surface not including a hollow structure, which can form a barrier for the supporting space 1112 and the assembly space 1113, prevent engine oil and dust from sputtering to the battery plate under the table surface, improve the yield of the battery plate, and reduce the equipment cost.

In some embodiments, the drive assembly 12 may include a control module, and the drive motor 123 includes a servo motor, with the control module being electrically connected to the servo motor. The output speed of the driving gear 121 can be adapted to the stress condition of the turntable main body 111 in the overturning process through the control of the servo motor, so that the turntable main body 111 can obtain a uniform rotation effect, and the overturning reliability of the flower basket is improved. As shown in the analysis of the force applied to the turntable main body 111 in the forward and reverse rotation processes in fig. 3, the force applied to the turntable main body 111 in the overturning process after carrying the basket is two sections of sinusoidal curves, so that a stable overturning effect can be obtained. The stress curves of the turntable main body 111 turned over under the condition of bearing the basket and not bearing the basket can be sinusoidal.

As shown in fig. 4, the servo motor may be located at the outer side of the bottom space of the turntable body 111 to avoid assembling and meshing interference of the driving gear 121 and the driven gear 122. The servo motor may be assembled to the bracket 112.

The present disclosure further provides a cleaning apparatus comprising the above-described conveying mechanism 1.

The driving assembly 12 for driving the turntable main body 111 comprises a driving gear 121 and a driven gear 122, the driven gear 122 is assembled on the rotating main body, the driving of the rotating main body can be realized through the engagement of the driving gear 121 and the driven gear 122, which are connected with the output shaft of the driving motor 123, the transmission is stable, and the problems that the basket falls off and fragments of battery pieces are caused in the overturning movement process due to the transmission of other modes such as a belt are avoided.

It should be noted that the cleaning device may be a tank type cleaning machine used in a cleaning process in the production of a crystalline silicon battery, and the conveying mechanism 1 may be a turnover conveying mechanism 1 of a basket for holding a silicon wafer in a cell before entering the tank type cleaning machine.
