Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0043] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0044] As described in the background technology of the present application, in the related art, during the process of the conveyor belt conveying the objects to be conveyed, the conveyor belt may be offset relative to the rotating wheel. When the conveyor belt has been conveying for a long time, the edge of the offset conveyor belt may interfere with the frame, thereby affecting the transmission efficiency of the objects to be conveyed, such as battery cells.

[0045] In order to solve the technical problems mentioned in the background technology, the utility model provides a conveying device and a battery cell production equipment. In the conveying device, a groove is provided on one of the rotating wheel and the conveyor belt cooperating with the rotating wheel, and a limiting piece cooperating with the groove is provided on the other. In this way, when the conveyor belt cooperates with the rotating wheel to convey the objects to be conveyed, the limiting piece can be limited by the groove, thereby achieving the limitation of the conveyor belt relative to the rotating wheel, thereby avoiding the displacement of the conveyor belt relative to the rotating wheel and improving the conveying efficiency of the conveying device for the objects to be conveyed.

[0046] The present application is described in detail below through specific embodiments:

[0047] See also Figure 1-Figure 4 The embodiment of the present application provides a conveying device 100, which includes a frame 110, a rotating wheel 140, a conveyor belt 130, a driving member 120 and a limiting structure 150, wherein the rotating wheel 140 is rotatably arranged on the frame 110; the conveyor belt 130 cooperates with the rotating wheel 140; the driving member 120 is transmission-connected with the rotating wheel 140 to drive the rotating wheel 140 to drive the conveyor belt 130 to convey the object to be conveyed along the conveying direction; the limiting structure 150 includes a groove 151 and a limiting member 152 cooperating with the groove 151, one of the groove 151 and the limiting member 152 is arranged on the rotating wheel 140, and the other is arranged on the conveyor belt 130.

[0048] The rotating wheel 140 may be a roller, a gear 141 or the like, and the driving member 120 may be an electric driving machine, a pneumatic driving machine or the like. The driving member 120 is connected to the rotating wheel 140 by transmission means that the driving member 120 may be connected to the rotating wheel 140 via a transmission assembly, for example, the driving member 120 may be connected to the rotating wheel 140 via a gear 141 transmission assembly or a conveyor belt 130 transmission assembly.

[0049] In addition, the above-mentioned limiting member 152 can be a strip limiting member 152 or a block limiting member 152. The above-mentioned limiting structure 150 includes a groove 151 and a limiting member 152 matched with the groove 151, one of the groove 151 and the limiting member 152 is arranged on the rotating wheel 140, and the other is arranged on the conveyor belt 130. It should be understood that when the groove 151 is arranged on the rotating wheel 140, the limiting member 152 is arranged on the surface of the side of the conveyor belt 130 that matches the rotating wheel 140, and vice versa, when the limiting member 152 is arranged on the rotating wheel 140, the limiting member 152 is arranged on the surface of the conveyor belt 130 that matches the rotating wheel 140.

[0050] In addition, the above-mentioned conveying direction refers to the conveying direction of the conveyor belt 130, that is, the length direction of the conveyor belt 130. Figure 1 The direction indicated by the X arrow in the figure, and the conveying direction mentioned below refers to the direction indicated by the X arrow. The object to be conveyed can be a battery cell, a material tray, or a material tray with battery cells, etc.

[0051] Therefore, in this embodiment, since the driving member 120 is connected with the rotating wheel 140 in transmission, and the rotating wheel 140 cooperates with the conveyor belt 130, when the driving member 120 drives the rotating wheel 140 to rotate relative to the frame 110, the rotating wheel 140 can drive the conveyor belt 130 to be transported along the conveying direction. In this way, when the conveyor belt 130 carries the objects to be transported, the conveyor belt 130 can drive the objects to be transported to be transported along the conveying direction. Because one of the groove 151 and the limiting member 152 is arranged on the rotating wheel 140 and the other is arranged on the conveyor belt 130, when the conveyor belt 130 cooperates with the rotating wheel 140, the limiting member 152 cooperates with the groove 151, and the groove wall of the groove 151 can limit the limiting member 152, thereby preventing the conveyor belt 130 from deviating relative to the rotating wheel 140 during the transmission process, thereby improving the transmission efficiency of the conveyor belt 130 for the objects to be transmitted.

[0052] In addition, optionally, the groove 151 is cut along the radial direction of the rotating wheel 140, and the cross-sectional shape of the groove 151 can be square, circular, trapezoidal, etc. The specific depth of the groove 151 is not limited, and those skilled in the art can set it accordingly according to actual conditions.

[0053] In addition, it is worth noting that one of the above-mentioned groove 151 and the limiter 152 is arranged on the rotating wheel 140 and the other is arranged on the conveyor belt 130, which means that when the groove 151 is arranged on the rotating wheel 140, the limiter 152 is arranged on the conveyor belt 130, or, when the groove 151 is arranged on the conveyor belt 130, the groove 151 is arranged on the rotating wheel 140.

[0054] In some possible embodiments, see Figure 2 and Figure 3The rotating wheel 140 is a gear 141, and a surface of one side of the conveyor belt 130 that cooperates with the gear 141 is provided with a toothed structure that meshes with the gear teeth of the gear 141. The limiter 152 is provided on the gear 141, and the groove 151 is provided on the conveyor belt 130.

[0055] Since one side surface of the conveyor belt 130 that cooperates with the gear 141 is provided with a tooth structure that meshes with the teeth of the gear 141, when the gear 141 rotates, the teeth on the gear 141 can act on the tooth structure on the conveyor belt 130, thereby avoiding the conveyor belt 130 from slipping relative to the gear 141 and ensuring the synchronization of transmission between the gear 141 and the conveyor belt 130.

[0056] In addition, since the conveyor belt 130 is a flexible structure, considering the stability of the setting of the limit member 152, the limit member 152 is set on the gear 141, and the groove 151 is set on the conveyor belt 130. In this way, the difficulty of setting the limit member 152 can be reduced, and the setting strength of the limit member 152 can be guaranteed, thereby further ensuring the stability of the conveying device 100 in conveying the objects to be conveyed.

[0057] In some possible embodiments, see Figure 5 , along the circumference of the gear 141 (i.e. Figure 3 A clamping groove 1411 is provided on the outer peripheral wall of the gear 141, and the limiting member 152 is a limiting ring, which is clamped in the clamping groove 1411.

[0058] A clamping groove 1411 is provided on the outer peripheral wall of the gear 141, and a limiting ring is clamped in the clamping groove 1411. On the one hand, due to the simple structure of the clamping groove 1411, the connection structure of the limiting ring on the gear 141 is simplified. On the other hand, the process difficulty of setting the limiting ring on the gear 141 is reduced. On still another hand, since the groove wall of the clamping groove 1411 can limit the limiting ring, the risk of the conveyor belt 130 being offset along the axial direction of the rotating wheel 140 is further reduced.

[0059] In some possible embodiments, see Figure 6 , along the radial direction of the gear 141 (i.e. Figure 6 The outer peripheral wall of the limiting ring is flush with the tooth top of the gear 141 or the height of the outer peripheral wall of the limiting ring is located between the tooth top and the tooth root of the gear 141.

[0060] If the outer wall of the limiting ring is higher than the tooth top of the gear 141 in the radial direction of the gear 141, when the conveyor belt 130 and the gear 141 cooperate, the fitting clearance between the conveyor belt 130 and the gear 141 will be increased, thereby affecting the transmission stability of the conveyor belt 130. Based on this, by making the outer wall of the limiting ring flush with the tooth top of the gear 141 or the height of the outer wall of the limiting ring is located between the tooth top and the tooth root of the gear 141, the fitting clearance between the conveyor belt 130 and the gear 141 and the contact area between the gear 141 and the conveyor belt 130 can be guaranteed, thereby improving the stability of the conveyor belt 130 in the process of conveying the objects to be conveyed.

[0061] In addition, the tooth top refers to the end of the gear teeth of the gear 141 away from the rotation center of the gear 141, that is, Figure 6 The position indicated by the arrow m1 in the figure is the tooth root, which refers to the end of the gear teeth of the gear 141 close to the rotation center of the gear 141. Figure 6 The position indicated by the arrow in m2.

[0062] In some possible embodiments, see Figure 4 and Figure 5 The limiting ring is located in the middle of the axial direction of the gear 141, and the groove 151 is located in the width direction of the conveyor belt 130 (i.e. Figure 4 The middle part of the structure (in the direction indicated by the Y arrow).

[0063] Since the limiting ring is located in the axial middle part of the gear 141 and the groove 151 is located in the width direction middle part of the conveyor belt 130, the limiting forces of the two opposite side walls of the groove 151 on the limiting ring are approximately equal. Then, the contact area between the gear teeth on one side of the limiting ring and the conveyor belt 130 is equal to the contact area between the gear teeth on the other side of the limiting ring and the conveyor belt 130, thereby further ensuring the transmission stability of the conveyor belt 130.

[0064] In addition, the above-mentioned middle part may be the absolute middle part or a position approximately in the middle part.

[0065] In some possible embodiments, the limiting member 152 and the groove 151 each include two, and along the axial direction of the gear 141, the two limiting rings are respectively arranged close to the two ends of the gear 141, and the two grooves 151 are respectively arranged close to the two side edges of the conveyor belt 130.

[0066] Therefore, the stability of the conveyor belt 130 in conveying the object to be conveyed can be improved by respectively cooperating with the two grooves 151 and the two limit members 152 .

[0067] In some possible embodiments, along the axial direction of the rotating wheel 140 , the matching clearance between the limiting member 152 and the groove 151 is h, and 0.5 mm≤h≤1 mm.

[0068] If the fitting clearance between the limit member 152 and the groove 151 is less than 0.5 mm, the fitting accuracy between the limit member 152 and the groove 151 is relatively high, which increases the process difficulty of the fitting between the limit member 152 and the groove 151. In addition, since the fitting clearance between the limit member 152 and the groove 151 is relatively small, the groove 151 on the conveyor belt 130 is easily worn during the process of the rotating wheel 140 driving the conveyor belt 130 to transport, thereby affecting the limiting of the conveyor belt 130 by the fitting between the limit member 152 and the groove 151.

[0069] If the fitting clearance between the limit member 152 and the groove 151 is greater than 1 mm, the fitting accuracy between the limit member 152 and the groove 151 is low. Since the fitting clearance between the limit member 152 and the groove 151 is large, the conveyor belt 130 may be offset relative to the rotating wheel 140 within a range greater than 1 mm, which may easily cause the edge of the conveyor belt 130 to contact the frame 110 and wear, thereby affecting the service life of the conveyor belt 130.

[0070] Based on this, by making the fitting clearance between the limit member 152 and the groove 151 between 0.5mm and 1mm, it can not only reduce the fitting difficulty between the limit member 152 and the groove 151, but also avoid a large range of deviation of the conveyor belt 130, thereby improving the service life of the conveyor belt 130.

[0071] For example, the matching clearance between the limiting member 152 and the groove 151 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0072] In some possible embodiments, see Figure 5 , along the axial direction of the rotating wheel 140, the width of the groove 151 is d, 5mm≤d≤8mm.

[0073] If the width of the groove 151 is less than 5 mm, the width of the groove 151 is narrow, and the width of the limiting member 152 that can cooperate with the groove 151 is also small, thereby affecting the matching strength between the limiting member 152 and the groove 151, and further affecting the effect of the limiting structure 150 on the conveyor belt 130. If the width of the groove 151 is greater than 8 mm, the width of the groove 151 is large, thereby reducing the contact area between the rotating wheel 140 and the conveyor belt 130, affecting the matching stability between the rotating wheel 140 and the conveyor belt 130. Based on this, the width of the groove 151 is between 5 mm and 8 mm. In this way, the matching strength between the limiting member 152 and the groove 151 and the contact area between the rotating wheel 140 and the conveyor belt 130 can be guaranteed, thereby improving the matching stability between the rotating wheel 140 and the conveyor belt 130.

[0074] For example, the width of the groove 151 may be 5 mm, 6 mm, 7 mm, 8 mm, etc.

[0075] In some possible embodiments, see Figure 7 The conveyor belt 130 is annular; the rotating wheels 140 include at least two, and at least two rotating wheels 140 are located at both ends of the conveyor belt 130 in the length direction.

[0076] Since the conveyor belt 130 is ring-shaped, the rotating wheel 140 can drive the ring-shaped conveyor belt 130 to circulate. Compared with a linear conveyor belt 130, the setting length of the conveyor belt 130 is shortened, and the preparation cost of the conveying device 100 is saved.

[0077] See also Figure 8 The embodiment of the present application also provides a battery cell production equipment 200, which includes: a process device 210, a material unloading device 220 and the conveying device 100 in the above embodiment, the process device 210 is used to process the parts to be conveyed; the material unloading device 220 is located downstream of the process device 210, and is used to unload the processed parts to be conveyed; the conveying device 100 is used to convey the parts to be conveyed from the process device 210 to the material unloading device 220.

[0078] Among them, the conveying device 100 in the embodiment of the present application can have the same structure as any of the conveying devices 100 in the above embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments, and the embodiment of the present application will not be repeated here.

[0079] In addition, the process device 210 may be a cleaning device, a high temperature device, a coating device, a screen device, etc., which are used to process battery cells. The unloading device 220 may be automatic unloading or semi-automatic unloading.

[0080] Since the battery cell production device includes the conveying device 100 in the above embodiment, the production efficiency of the battery cell production device is improved.

[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
