Description

Technical Field

[0001] This invention relates to an improved new energy lithium battery transfer mechanism. Background Technology

[0002] Currently, a new energy lithium battery transfer mechanism, as authorized in Announcement No. CN219258817 U on June 27, 2023, includes a frame, a conveying assembly, and multiple positioning fixture assemblies. The conveyor belt of the conveying assembly is mounted on the frame, and each positioning fixture assembly includes a positioning base. Multiple positioning bases are connected to the conveyor belt of the conveying assembly. The conveyor belt transports the lithium batteries on the multiple positioning bases to multiple workstations for testing. Since the conveyor belt is mounted on the drive wheel and the driven wheel, when the servo motor drives the drive wheel to rotate through the reducer, the conveyor belt can be driven along with the drive wheel and the driven wheel. When the conveyor belt, which was originally located on the upper surface of the frame, is driven to the lower surface of the frame, the conveyor belt located on the lower surface of the frame will deform due to gravity, resulting in a shortened service life of the conveyor belt. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide an improved new energy lithium battery transfer mechanism that avoids the conveyor belt from deforming due to gravity when it is transported to the lower surface of the frame, extends the service life of the conveyor belt, and saves costs.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: an improved new energy lithium battery transplanting mechanism, comprising a frame and a conveyor belt. A servo motor for driving the conveyor belt is installed on the frame. Multiple evenly spaced positioning fixtures are provided on the outer surface of the conveyor belt. Guide support bearings are respectively provided at the front and rear ends of each positioning fixture. The guide support bearings are fixed on the conveyor belt and are higher than the positioning fixtures. A guide support plate is provided below the frame. When the guide support bearing is driven by the conveyor belt to the lower surface of the frame, it contacts the upper surface of the guide support plate.

[0005] The beneficial effects of the improved new energy lithium battery transfer mechanism of the present invention are as follows: When the guide support bearing is driven by the conveyor belt to the lower surface of the frame and contacts the upper surface of the guide support plate, the guide support bearing provides guidance and support for the front and rear ends of the positioning fixture, preventing the lower part of the conveyor belt from deforming due to gravity during operation. The guide support bearing is set higher than the positioning fixture so that when it is driven by the conveyor belt to the lower surface of the frame (at which time the lithium battery product has been taken away by the robot), the guide support bearing can contact the upper surface of the guide support plate, so as to ensure that the guide support bearing can support the conveyor belt. It has the advantages of preventing it from deforming due to gravity, increasing the service life of the conveyor belt, and saving costs.

[0006] Preferably, the guide support plate is parallel to the conveyor belt, and both ends of the guide support plate are downwardly inclined plates. The inclined plates at both ends increase the angle between the end of the guide support plate and the frame, allowing the guide support bearing to easily slide into the guide support plate when it is driven by the conveyor belt to the lower end face of the frame.

[0007] Preferably, the guide support bearing includes two plastic-coated bearings and a U-shaped frame. The U-shaped frame is fixed to the conveyor belt by bolts, and the two plastic-coated bearings are rotatably arranged at both ends of the U-shaped frame. The U-shaped frame is used to install and support the guide support bearing.

[0008] Preferably, the front and rear ends of the frame are arc-shaped, and arc-shaped guide support blocks are provided on both sides of the front end and both sides of the rear end of the frame. The conveyor belt is located between the arc-shaped guide support blocks on both sides. Through the joint cooperation of the guide support bearings and the arc-shaped guide support blocks, although the speed is high during transmission and when the conveyor turns, the inertia and impact force are relatively reduced, and the transmission is more stable.

[0009] Preferably, the positioning fixture includes a fixed support plate and two adjustable support plates. The fixed support plate is fixed to the conveyor belt, and the adjustable support plates are symmetrically located at the front and rear ends of the fixed support plate. Each adjustable support plate includes a base and an adjusting plate. The base is fixed to the conveyor belt, and the adjusting plate is adjustablely mounted on the base. The positioning fixture adopts a split design and uses a centered distribution and adjustable fixed limit product method to meet the limit fixing requirements of large and small battery cells, saving costs and being compatible with lithium battery products of various sizes.

[0010] Preferably, the adjustment direction of the adjusting plate on the base is the transmission direction of the conveyor belt.

[0011] Preferably, the adjusting plate is provided with waist holes arranged along the conveyor belt transmission direction, and bolts passing through the through holes of the adjusting plate are locked and fixed to the base. The cooperation of the waist holes and bolts enables rapid adjustment.

[0012] Preferably, the base and the adjusting plate are provided with a protrusion and a groove that are arranged along the conveyor belt transmission direction and cooperate with each other. When adjusting the adjusting plate, only the adjusting plate needs to be slid. The groove and the protrusion play a guiding role, so that the waist hole can be quickly aligned with the mounting hole on the base, which facilitates the quick tightening of the bolts.

[0013] Preferably, each of the adjusting plates has side plates on both sides, forming a U-shape. The top of each side plate has a right-angle notch, supporting and limiting the sides and bottom of the lithium battery product. The fixed support plate supports the bottom of the lithium battery product. By supporting the bottom of the lithium battery product and limiting its front and rear sides, the lithium battery product is thus supported on the conveyor belt. The structure is simple and ingeniously designed.

[0014] Preferably, external threaded bearings are provided on both sides of the fixed support plate and both sides of the base, and support sidewalls are provided at the upper ends of both sides of the frame. The support sidewalls are higher than the conveyor belt, and the external threaded bearings are in contact with the upper end surfaces of the support sidewalls. This facilitates the smooth sliding of the positioning fixture on the frame, and the support sidewalls prevent the conveyor belt from deviating from its travel path during operation.

Detailed Implementation

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0026] See appendix Figure 1 As shown, this embodiment discloses an improved new energy lithium battery transfer mechanism, including a frame 10 and a conveyor belt 20. A drive wheel and a driven wheel are rotatably mounted on the frame 10. The conveyor belt 20 is sleeved on the drive wheel and the driven wheel. A servo motor 30 is mounted on the frame 10 to drive the conveyor belt 20. The servo motor 30 drives the drive wheel to rotate through a reducer 31. The drive wheel driving the conveyor belt 20 is a prior art. The drive wheel, the driven wheel and the inner side of the conveyor belt 20 are provided with mutually cooperating toothed structures. The toothed structures ensure that when the drive wheel is driven to rotate, the conveyor belt 20 can be driven to rotate through the meshing of the toothed structures. A plurality of evenly spaced positioning fixtures 40 are provided on the outer surface of the conveyor belt 20. The positioning fixtures 40 are used to support the lithium battery product 80.

[0027] In this embodiment, each positioning fixture 40 is equipped with guide support bearings 50 at its front and rear ends. The guide support bearings 50 are fixed to the conveyor belt 20 by bolts. A guide support plate 60 is provided below the frame 10. The guide support bearings 50 are higher than the positioning fixtures 40 to ensure that when the guide support bearings 50 are driven by the conveyor belt 20 to the lower surface of the frame 10, they contact the upper surface of the guide support plate 60. In this embodiment, the guide support plate 60 is parallel to the conveyor belt 20. Both ends of the guide support plate 60 are downwardly inclined plates 61. After the guide support bearings 50 slide from the upper surface of the frame 10 to the lower surface with the conveyor belt 20, they contact the upper surface of the guide support plate 60.

[0028] The guide support bearing 50 in this embodiment includes two plastic-coated bearings 51 and a U-shaped frame 52. The U-shaped frame 52 is fixed to the conveyor belt 20 by bolts. The two plastic-coated bearings 51 are rotatably disposed at both ends of the U-shaped frame 52. In this embodiment, the two plastic-coated bearings 51 are located on the outer side of both ends of the U-shaped frame 52.

[0029] The front and rear ends of the frame 10 are arc-shaped. Arc-shaped guide support blocks 70 are provided on both sides of the front end and both sides of the rear end of the frame 10. The conveyor belt 20 is located between the arc-shaped guide support blocks 70 on both sides to guide the conveyor belt 20.

[0030] In this embodiment, the positioning fixture 40 adopts a split structure, including a fixed support plate 41 and two adjustable support plates. The fixed support plate 41 is fixed to the conveyor belt 20 by bolts. The adjustable support plates are symmetrically located at the front and rear ends of the fixed support plate 41. The adjustable support plate includes a base 42 and an adjusting plate 43. The base 42 is fixed to the conveyor belt 20, and the adjusting plate 43 is adjustablely set on the base 42. The adjustment direction of the adjusting plate 43 on the base 42 is the transmission direction of the conveyor belt 20.

[0031] In order to enable the adjustment plate 43 to adjust its position in the direction of the conveyor belt 20, in this embodiment, the adjustment plate 43 is provided with a waist hole 44 arranged along the transmission direction of the conveyor belt 20, and the bolts through the through hole of the adjustment plate 43 are locked and fixed to the base 42.

[0032] To facilitate adjustment of the position of the adjusting plate 43, a protruding strip 46 and a groove 45, which are arranged along the transmission direction of the conveyor belt 20 and cooperate with each other, are provided between the base 42 and the adjusting plate 43. In this embodiment, the protruding strip 46 is provided on the lower end face of the adjusting plate 43, and the groove 45 is provided on the upper end face of the base 42. In this embodiment, multiple sets of protruding strips 46 and grooves 45 can be provided, but in this embodiment, only one set is provided, located in the middle of the base 42 and the adjusting plate 43.

[0033] In this embodiment, the positioning fixture 40 is moved by the conveyor belt 20. Each adjusting plate 43 has side plates 49 on both sides, and the whole is U-shaped. The top of the side plates 49 on both sides is provided with right angle notches 47, which support and limit the two sides and bottom of the lithium battery product 80. The fixed support plate 41 supports the bottom of the lithium battery product 80.

[0034] like Figure 6 As shown, in this embodiment, the two side plates 49 are detachably connected to both ends of the adjustment plate 43 by bolts, so that different side plates 49 can be replaced according to different lithium battery products 80 to improve its applicability.

[0035] In this embodiment, external threaded bearings 48 are provided on both sides of the fixed support plate 41 and both sides of the base 42. Support sidewalls 11 are provided on the upper ends of both sides of the frame 10. The support sidewalls 11 are higher than the conveyor belt 20. The external threaded bearings 48 are in contact with the upper end face of the support sidewalls 11. The support sidewalls 11 are higher than the conveyor belt 20. When the fixed support plate 41 and the two adjustable support plates are driven on the frame 10 along with the conveyor belt 20, the external threaded bearings 48 on both sides slide on the support sidewalls 11 on both sides of the frame 10, ensuring the stability of the conveyor belt 20 transmission.

[0036] The working principle of this embodiment is as follows: the servo motor 30 drives the conveyor belt 20 to move a fixed distance along the S direction. When it moves one interval (from the position of positioning fixture 40-1 to the position of positioning fixture 40-2), the conveyor belt 20 stops. Then it moves another interval and stops again. That is, when both positioning fixtures 40-1 and 40-2 are at their loading positions, the lithium battery product 80 is placed on them. This process is repeated. Figure 1 For example, the left side is for loading and the right side is for unloading. Inspection stations can be inserted between the positioning fixtures 40. Loading, inspection, and unloading are synchronized when the conveyor belt 20 stops. In the figure, the positioning fixture 40 starts from the loading position, moves and stops, runs through each inspection station, and circulates. When it reaches the unloading end, the material is unloaded by the robotic arm. During the operation, the loading and unloading robotic arms grab two lithium battery products 80 at a time.

[0037] To achieve automated monitoring, the following photoelectric sensors can also be installed on the rack 10:

[0038] A photoelectric sensor 12 is installed on the frame 10. In this embodiment, the photoelectric sensor 12 is located on one side of one of the positioning fixtures 40 on the upper surface of the frame 10. The photoelectric sensor 12 is a Panasonic PM-T45-P model and is used to monitor whether each set of positioning fixtures 40 on the conveyor belt 20 has returned to the zero position.

[0039] A number of photoelectric sensors 13, corresponding to the number of positioning fixtures 40 on the upper surface of the frame 10, are installed on the frame 10. The photoelectric sensors 13 can be Panasonic CX-421-P models, such as... Figure 1 and 2 As shown, there are nine positioning fixtures 40 on the upper surface of the frame 10, and correspondingly, nine photoelectric sensors 13 are also provided, located on one side of the corresponding positioning fixtures 40. These sensors are used to sense whether a lithium-battery-free product 80 is present within the positioning fixtures 40 on the upper surface of the frame 10.

[0040] Photoelectric sensors 14 are installed at both ends of the frame 10. Panasonic CX-421-P model can be used to detect the material passing through the lithium battery product 80 on the positioning fixture 40 on the conveyor belt 20 at both ends of the conveyor belt 20. It can also prevent the material from being bumped by the machine if one sensor fails to detect it, thus providing dual protection.

[0041] like Figure 1 , 2 As shown, the photoelectric sensors are arranged at an angle, and to facilitate the installation of various photoelectric sensors, the nine photoelectric sensors 13 in this embodiment are alternately arranged on both sides of the frame 10. Figure 8As shown, each photoelectric sensor (photoelectric sensor 12, photoelectric sensor 2, and photoelectric sensor 3) is fixed on an inclined bracket 15. The inclined bracket 15 has a pair of mirrored arc-shaped waist holes 17. Each photoelectric sensor has two mounting holes 16, corresponding to the two arc-shaped waist holes 17. Locking bolts are fitted into the two mounting holes 16 of the photoelectric sensors, passing through the two arc-shaped waist holes 17 to fix the photoelectric sensors to the inclined bracket 15. The mirrored arc-shaped waist holes 17 allow for fine-tuning of each photoelectric sensor on the inclined bracket 15, facilitating adjustment of the sensor angle according to different installation environments.

[0042] like Figure 7 As shown, the inclined bracket 15, on which the photoelectric sensor 2 13 is installed, is fixed on the support base. The support base is located below the guide support plate 60, and its upper end face is provided with a slot. The guide support plate 60 is located in the slot, which serves to support and fix the guide support plate 60.

[0043] An inclined bracket 15, which is equipped with photoelectric sensor 2 13 and photoelectric sensor 3 14, is fixed to the side of the frame 10.

[0044] This embodiment has the following effects:

[0045] First, cost-saving and size compatibility: The design of the split positioning fixture 40, the guide support at the front and rear ends of the plastic-coated bearing 51, and the arc-shaped guide support block 70 reduce inertia and impact force during transmission and conveying turns, making the transmission more stable. It also prevents the conveyor belt 20 from deforming due to gravity during operation, extending its service life and saving costs. Furthermore, the positioning fixture 40's adjustable fixed limit method for centering and distributing the support plate of the lithium battery product 80 meets the limit and fixation requirements of lithium battery products 80 for both large and small materials.

[0046] Second, no handling required, stable transmission: The servo motor 30 and reducer 31 are used for speed ratio to drive the conveyor belt 20. The support bearing 50 and external thread bearing 48 are used as the guiding support structure to ensure the accurate position and torque requirements of the conveyor belt 20 when starting and stopping. This makes it convenient for lithium battery products 80 to perform various testing items in sections on the conveyor belt 20 without having to transport the conveyor line 20 out of the middle, thus meeting the testing needs.

[0047] Third, the equipment is small in size and highly efficient: because feeding, detection and unloading are carried out synchronously when the conveyor belt 20 stops, CT is saved and efficiency is improved; the equipment is small in size and the length can be flexibly defined according to configuration requirements, making it easy to be integrated into the double-speed chain of on-site production, meeting the needs of large-scale and modern production.

[0048] Fourth, by utilizing digital acquisition and control, and information feedback transmitted through sensor signals, the correct position during the transmission of the conveyor line is ensured.

[0049] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
