[0045] See also Figures 1 to 3, is a conveying mechanism 100 of an embodiment of the utility model, comprising a conveyor line 10, a support frame 20, a driving member 30, a connecting frame 40 and a roller 50. The conveyor line 10 is used to convey a workpiece 90 to move in a first direction to ensure the transportation demand of the workpiece 90. The support frame 20 is connected to the conveyor line 10, and the support frame 20 is used to set up various components on the conveyor line 10. The driving member 30 is installed on the support frame 20; the connecting frame 40 is connected to the driving member 30, and the connecting frame 40 is movably connected to the support frame 20. The roller 50 is rotatably connected to the connecting frame 40, and the rotation center line of the roller 50 extends along the third direction. Among them, the driving member 30 drives the support frame 20 to approach or move away from the conveyor line 10 along the second direction, and the support frame 20 drives the roller 50 to move together, and the roller 50 is used to abut against the workpiece 90 to locate the position of the workpiece 90 in the first direction. The workpiece 90 on the conveyor line 10 is blocked by the roller 50, thereby achieving the positioning of the workpiece 90. When the positioned workpiece 90 needs to continue to be conveyed, the driving member 30 drives the connecting frame 40 and the roller 50 away from the conveyor line 10. The roller 50 will rotate relative to the connecting frame 40 during the movement away from the conveyor line 10, thereby preventing the roller 50 from causing wear or even deformation of the workpiece 90, thereby protecting the battery and improving the stability of battery transportation.

[0046] Furthermore, the conveyor line 10 is arranged in a long strip shape extending along the first direction, the workpiece 90 is placed on the conveyor line 10, and the workpiece 90 is driven to move along the first direction by the conveyor line 10. It can be understood that the conveyor line 10 can be a belt conveyor structure or a cylindrical conveyor structure. The specific conveying structure of the conveyor line 10 is not limited here, and it is sufficient to ensure that the conveyor line 10 can convey and move the workpiece 90. Furthermore, the two ends of the conveyor line 10 in the first direction are the head end and the tail end respectively, the workpiece 90 is conveyed from the head end to the tail end, and the support frame 20 is installed at the tail end position of the conveyor line 10 to position and block the workpiece 90 at the tail end position of the conveyor line 10.

[0047] Furthermore, the support frame 20 includes a support rod 21 and a fixing plate 22. The support rod 21 is in the shape of a long strip and extends along the second direction. The support rod 21 is connected to the conveyor line 10 to fix the support frame 20 at a specified position of the conveyor line 10. The fixing plate 22 is in the shape of a straight plate and is mounted on the support rod 21. The support rod 21 sets the fixing plate 22 on one side of the conveyor line 10 in the second direction. In this embodiment, a plurality of support rods 21 are provided, and each support rod 21 is relatively arranged at both ends of the fixing plate 22 in the third direction to improve the stability of the support of the fixing plate 22.

[0048] Further, the driving member 30 is mounted on the fixed plate 22, and the driving member 30 is arranged at the middle position of the fixed plate 22 in the third direction, so that the driving member 30 is located at the center of gravity of the fixed plate 22, ensuring the stability of the driving member 30 driving the connecting frame 40. It can be understood that the driving member 30 can be one of a cylinder, a hydraulic cylinder, a gear rack mechanism, a screw mechanism or a belt transmission mechanism. The specific structure of the driving member 30 is not limited here, and it is sufficient to ensure that the driving member 30 can drive the connecting frame 40 to move along the second direction. In this embodiment, the driving member 30 is a cylinder, the cylinder body of the driving member 30 is connected and fixed to the fixed plate 22, and the cylinder rod of the driving member 30 passes through the fixed plate 22 and is connected and fixed to the connecting frame 40.

[0049] Furthermore, the connecting frame 40 includes a connecting strip 41 and a mounting block 42. The connecting strip 41 is in the shape of a long strip, and the connecting strip 41 extends along the third direction. The connecting strip 41 is connected to the driving member 30 to ensure that the driving member 30 drives the movement of the connecting frame 40. The mounting block 42 extends from the connecting strip 41 toward the direction close to the conveyor line 10 and is movably connected to the support frame 20, and the roller 50 is hinged on the mounting block 42. In this embodiment, the number of the mounting blocks 42 is multiple, and each mounting block 42 is arranged on the connecting strip 41 at intervals along the third direction, and the roller 50 is arranged between the mounting blocks 42. Specifically, the number of the mounting blocks 42 is two, and the two mounting blocks 42 are respectively arranged at the two ends of the connecting strip 41 in the third direction, and the two ends of the roller 50 in the third direction are respectively hinged to the two mounting blocks 42. In another embodiment, the number of the mounting blocks 42 may be greater than two, and each mounting block 42 is arranged on the connecting strip 41 at intervals along the third direction, and the rollers 50 are respectively arranged between two adjacent mounting blocks 42 in the third direction. The advantage of doing so is that in the third direction, the conveyor line 10 will simultaneously convey the workpieces 90 of multiple channels. By setting a plurality of relatively independent rollers 50, the number and positions of the rollers 50 correspond to the number and positions of the workpieces 90 conveyed on the conveyor line 10. When one roller 50 is damaged, it is only necessary not to place the workpiece 90 in the corresponding channel, and the normal operation of the remaining channels can be guaranteed, thereby ensuring the conveying efficiency of the workpiece 90.

[0050] Furthermore, the mounting block 42 includes a buffer portion 421 and an extension portion 422. The buffer portion 421 is connected to the connecting strip 41, and the extension portion 422 is arranged on a side of the buffer portion 421 away from the connecting strip 41. The roller 50 is hinged on the extension portion 422. The buffer portion 421 and the extension portion 422 are both in the shape of a straight plate. In the first direction, the width dimension of the buffer portion 421 is smaller than the width dimension of the extension portion 422. By making the width dimension of the buffer portion 421 smaller than the width dimension of the extension portion 422, and by making the width dimension of the buffer portion 421 smaller than the width dimension of the extension portion 422, it is ensured that when the roller 50 positions and blocks the workpiece 90, the impact load applied by the workpiece 90 to the roller 50 will be transmitted to the mounting block 42, and the mounting block 42 will absorb the impact load through the buffer portion 421, thereby avoiding the impact load from being concentrated at the hinge position between the roller 50 and the mounting block 42 to cause damage, thereby extending the service life of the component.

[0051] Furthermore, the connecting frame 40 further includes a sliding sleeve 43. The sliding sleeve 43 is in the shape of a hollow circular tube, and is sleeved on the outer side of the support rod 21. The sliding sleeve 43 is slidably arranged on the support rod 21. The sliding sleeve 43 is passed through the connecting strip 41 and fixed to the connecting strip 41. Through the sliding connection between the sliding sleeve 43 and the support rod 21, the movement of the connecting frame 40 driven by the driving member 30 is guided, thereby improving the stability of the connecting frame 40 moving in the second direction. In this embodiment, the number of the sliding sleeves 43 is the same as the number of the support rods 21, and each sliding sleeve 43 is relatively arranged at the two ends of the connecting strip 41 in the third direction, and each sliding sleeve 43 is sleeved on the outer side of each support rod 21 in a one-to-one correspondence.

[0052] Furthermore, the roller 50 includes a rotating shaft 51 and a sleeve 52. The rotating shaft 51 is cylindrical, and the central axis of the rotating shaft 51 is extended along the third direction. The two ends of the rotating shaft 51 in the third direction are respectively inserted into the mounting block 42, and can rotate relative to the mounting block 42. The sleeve 52 is in the shape of a circular tube, and the sleeve 52 is sleeved on the outside of the rotating shaft 51. The sleeve 52 is used to abut against the workpiece 90 to position and block the workpiece 90. In this embodiment, the sleeve 52 is a rubber part to absorb the stress during the abutment process between the workpiece 90 and the roller 50, thereby avoiding wear or deformation of the workpiece 90. Preferably, the rotating shaft 51 and the sleeve 52 are integrally formed.

[0053] In summary, the embodiment of the utility model provides a conveying mechanism 100, which has the following beneficial effects:

[0054] By rotatably connecting the roller 50 and the connecting frame 40 and positioning the roller 50 against the workpiece 90, the roller 50 can rotate relative to the workpiece 90 during the lifting process, and the sliding friction between the traditional structure block and the workpiece 90 is converted into a rolling friction between the roller 50 and the workpiece 90. The force on the workpiece 90 is reduced by changing the nature of the friction force, thereby avoiding the workpiece 90 from being lifted during the lifting process of the roller 50, and also avoiding the problem of wear or even deformation of the workpiece 90, thereby improving the stability of the conveying of the workpiece 90.

[0055] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
