Description

Technical Field

[0001] The utility model relates to the field of lithium ion battery production, in particular to a NG product buffer mechanism. Background Art

[0002] At present, the production mode of lithium-ion batteries is mainly a batch assembly line mode. When NG battery cells are detected in the production process of lithium-ion batteries, the robot needs to grab the NG battery cells on the assembly line and cache them in a cache mechanism. However, when multiple robots are simultaneously gripping and conveying multiple lithium batteries, and only one of the NG batteries needs to be discharged, since the movements of multiple robots are synchronized, the robots need to avoid positions when releasing materials. Therefore, multiple robots cannot directly place the NG batteries in the cache mechanism, otherwise a larger cache mechanism is required.

[0003] For example, in the Chinese utility model patent with the authorization announcement date of 2020.05.22 and the authorization announcement number of CN 210594168 U, a cache mechanism for a power battery conveyor line is disclosed, which includes a conveyor line, a gantry bracket, a clamp and a storage platform. The gantry bracket is arranged above the conveyor line, and the clamp is movably connected to the gantry bracket through a driving device. The clamp is connected to a clamp, and the clamp is located above the conveyor line. The storage platform is arranged on one side of the conveyor line, which is used to store the batteries on the conveyor line clamped by the clamp, such as the NG battery platform. The NG battery products on the conveyor line are clamped by the clamp and the clamp, and the NG battery products can be removed from the conveyor line. The cache mechanism can cache NG battery products through the storage platform, but the storage platform can store a limited number of NG battery products. If more NG battery products are to be stored, a larger storage platform is required. During the transmission process along the direction of movement of the line body, it will be limited by the site and space.

[0004] Therefore, how to cache more NG battery cell products in a limited space is a technical problem that needs to be solved at present. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide an NG product caching mechanism which can cache more NG battery cell products, save space, and reduce the overall production cost.

[0006] The technical solution of the utility model is as follows:

[0007] A NG product caching mechanism comprises an NG product caching conveying device and a transfer and picking device, wherein the transfer and picking device comprises a linear motion component, a material receiving and lifting cylinder and a receiving plate, wherein the linear motion component is arranged below the NG product caching conveying device, and the receiving plate is arranged on the linear motion component through the material receiving and lifting cylinder, and is movably located above the NG product caching conveying device, and the receiving plate can reciprocate along the conveying direction of the NG product caching conveying device under the action of the linear motion component, and the NG battery cell product is received by the receiving plate and placed on the NG product caching conveying device under the action of the material receiving and lifting cylinder.

[0008] Furthermore, the linear motion assembly includes a linear guide rail, a movable base and a transfer material removal cylinder. The linear guide rail is arranged along the conveying direction of the NG product cache conveying device. The movable base is movably arranged on the linear guide rail. The cylinder shaft of the transfer material removal cylinder is connected to the movable base. The transfer material removal cylinder is used to drive the movable base to reciprocate along the linear guide rail. The material receiving lifting cylinder is arranged on the movable base.

[0009] Furthermore, the linear guide rails are provided with two opposite ones, namely a first linear guide rail and a second linear guide rail, and the movable base is slidably connected to the first linear guide rail and the second linear guide rail through a first slider and a second slider respectively.

[0010] Furthermore, a first buffering limit assembly and a second buffering limit assembly are respectively provided at both ends of the first linear guide rail and the second linear guide rail.

[0011] Furthermore, a first material receiving lifting cylinder and a second material receiving lifting cylinder are respectively provided at both ends of the movable base, a first receiving plate is provided on the cylinder shaft of the first material receiving lifting cylinder, and a second receiving plate is provided on the cylinder shaft of the second material receiving lifting cylinder, and the first receiving plate and the second receiving plate are arranged opposite to each other.

[0012] Furthermore, first supporting bars are disposed on the first receiving plate and the second receiving plate relative to each other.

[0013] Furthermore, the NG product buffer conveying device includes a buffer belt and a belt-pulling stepper motor, and the belt-pulling stepper motor is arranged on one side of the end of the buffer belt to drive the buffer belt to operate.

[0014] Furthermore, two second support strips are arranged on the cache belt opposite to each other along the belt.

After receiving the material, it is driven down by the material receiving lifting cylinder to place the NG battery cell products on the NG product cache conveying device. When the NG product cache conveying device is full of NG battery cell products, the NG battery cell products can be promptly conveyed to the next workstation through the NG product cache conveying device, so as to facilitate the NG product cache conveying device to be used again to cache new NG battery cell products.

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0032] Example

[0033] This embodiment provides a NG product buffer mechanism suitable for removing NG battery cell products in lithium-ion battery production. Figure 1 It includes two parts: an NG product cache conveying device 1 and a transfer and picking device 2. The NG product cache conveying device 1 is used to cache and convey the NG battery cell products. The transfer and picking device 2 receives the NG battery cell products and places them on the NG product cache conveying device 1. The NG product cache conveying device 1 can store more NG battery cell products relative to the storage platform, and multiple NG battery cell products are conveyed in a front-to-back arrangement.

[0034] Combination Figure 2 As shown, the transfer material taking device 2 includes a linear motion component 21, a material receiving and lifting cylinder, and a receiving plate. The linear motion component 21 is arranged below the NG product buffer conveying device 1. The receiving plate is arranged on the linear motion component 21 through the material receiving and lifting cylinder, and is movably located above the NG product buffer conveying device 1. The receiving plate can reciprocate along the conveying direction of the NG product buffer conveying device 1 under the action of the linear motion component 21, and the NG battery cell product is received by the receiving plate and placed on the NG product buffer conveying device 1 under the action of the material receiving and lifting cylinder. When there are multiple NG battery cell products, the action is repeated, and the NG product buffer conveying device 1 conveys the previous NG battery cell product forward by one position, thereby freeing up a space for the next NG battery cell product to be placed.

[0035] The linear motion assembly 21 includes a linear guide, a movable base 213 and a transfer material removal cylinder 214. The linear guide is arranged along the conveying direction of the NG product buffer conveying device 1. The movable base 213 is movably arranged on the linear guide. The cylinder shaft of the transfer material removal cylinder 214 is connected to the movable base 213. The transfer material removal cylinder 214 is used to drive the movable base 213 to move back and forth along the linear guide. The material receiving and lifting cylinder is arranged on the movable base 213, so that the receiving plate on the material receiving and lifting cylinder can be driven to move back and forth along the conveying direction of the NG product buffer conveying device 1 through the transfer material removal cylinder 214. The use of cylinder drive has relatively low cost, large torque output, easy control, fast response speed, stable force transmission, high reliability, energy saving and environmental protection, and simple installation and maintenance.

[0036] In this embodiment, two linear guide rails are provided opposite to each other, namely, a first linear guide rail 211 and a second linear guide rail 212, and the movable base 213 is slidably connected to the first linear guide rail 211 and the second linear guide rail 212 respectively through a first slider 215 and a second slider 216. The use of two linear guide rails can ensure the movement stability of the movable base 213.

[0037] The first and second linear guide rails 211 and 212 are provided with first and second buffer stopper assemblies 217 and 218 at their two ends. The travel of the movable base 213 is limited by the first and second buffer stopper assemblies 217 and 218 to prevent the movable base 213 from being separated from the linear guide rails; the first and second buffer stopper assemblies 217 and 218 also have a buffering effect. When the movable base 213 collides with the first and second buffer stopper assemblies 217 and 218, the first and second buffer stopper assemblies 217 and 218 can provide a buffering force to stop the movable base 213 without causing damage to the movable base 213.

[0038] In this embodiment, two groups of the material receiving lifting cylinders and receiving plates are relatively arranged to ensure stability when receiving NG battery cell products. Specifically, the first material receiving lifting cylinder 22 and the second material receiving lifting cylinder 23 are respectively arranged at both ends of the movable base 213, and the first material receiving lifting cylinder 22 is provided with a first receiving plate 24 on the cylinder shaft, and the second material receiving lifting cylinder 23 is provided with a second receiving plate 25 on the cylinder shaft. The first receiving plate 24 and the second receiving plate 25 are arranged opposite to each other to form two relative receiving surfaces. The first receiving plate 24 and the second receiving plate 25 are relatively movable and are located above the NG product cache conveying device 1. The first receiving plate 24 and the second receiving plate 25 can reciprocate along the conveying direction of the NG product cache conveying device 1 under the action of the linear motion component 21. When receiving the materials, the first receiving plate 24 and the second receiving plate 25 are driven by the linear motion component 21 to move to the bottom of the NG battery cell product on the manipulator, and the NG battery cell product is received by the first receiving plate 24 and the second receiving plate 25; after receiving the materials, the NG battery cell product is placed on the NG product cache conveying device 1 under the action of the first material receiving lifting cylinder 22 and the second material receiving lifting cylinder 23. If there are multiple NG battery cell products, the action is repeated to place the NG battery cell product on the NG product cache conveying device 1. Multiple NG battery cell products are arranged in a front-to-back state along the cache belt 11 and are separated by a fixed distance. If the direction of the NG battery cell product is incorrect, the direction of the NG battery cell product can be adjusted by adding a rotating structure to the manipulator.

[0039] Specifically, the first receiving plate 24 and the second receiving plate 25 are provided with first support bars 26. The first support bars 26 can play the role of reinforcing ribs, thereby improving the mechanical strength of the first receiving plate 24 and the second receiving plate 25. At the same time, the first support bars 26 can also be used to support NG battery cell products, reduce the contact area of ​​NG battery cell products with the first receiving plate 24 and the second receiving plate 25, and facilitate the first receiving plate 24 and the second receiving plate 25 to quickly separate from the NG battery cell products after conveying the NG battery cell products to the corresponding positions, thereby completing the transfer and conveying of the NG battery cell products.

[0040] The NG product buffering and conveying device 1 includes a buffering belt 11 and a belt-pulling stepping motor 12. The buffering belt 11 is used to buffer the NG battery cell products. The belt-pulling stepping motor 12 is arranged at one end of the buffering belt 11 to drive the buffering belt 11 to operate. Specifically, rollers are arranged at both ends of the buffering belt 11. The buffering belt 11 is rotatably mounted on the support frame through two rollers. The belt-pulling stepping motor 12 is mounted on the support frame and is connected to one of the rollers, thereby driving the roller to rotate in a directional manner, and providing driving force for the transmission of the buffering belt 11.

[0041] Specifically, two second support bars 111 are arranged along the buffer belt 11. The second support bars 111 can act as reinforcing ribs, thereby improving the mechanical strength of the buffer belt 11. At the same time, the second support bars 111 can also support NG battery products, reduce the contact area between the NG battery products and the buffer belt 11, and facilitate the NG battery products to separate from the buffer belt 11, thereby completing the unloading of the NG battery products.

[0042] In summary, the NG product cache mechanism uses a cache belt to replace the storage platform. Compared with the storage platform, it can store more NG battery products. Its working principle is to receive the NG battery products grabbed by the robot from the assembly line through the two receiving plates above the cache belt, and drive the movement to the bottom of the NG battery products on the robot through the linear motion component. After receiving the material, the material receiving lifting cylinder drives the NG battery products to be placed on the cache belt. If there are multiple NG battery products, repeat the above actions to arrange multiple NG battery products in front and back equidistantly along the transmission direction of the cache belt. When the cache belt is full of NG battery products, the NG battery products can be promptly transported to the next station through the cache belt, so that the cache belt can be used to cache new NG battery products again. The structural design of the NG product cache mechanism has high space utilization and is not limited by site and space limitations, thereby greatly reducing the overall production cost.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
