[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figures 1 to 3As shown, an embodiment of the present invention provides a battery automatic coding device, including an operating table 10, a conveying mechanism 20, a fixture 30 and a coding mechanism 40. The fixture 30 is used to clamp the product to be coded. The fixture 30 is installed on the conveying mechanism 20. Under the action of the conveying mechanism 20, the fixture 30 runs back and forth between the loading position and the coding position. The coding mechanism 40 is installed on the operating table 10 and is used to perform coding operations on the product to be coded clamped by the fixture. For example, the conveying mechanism 20 can be a linear conveying mechanism. In this case, the loading position and the conveying position are relatively arranged at the two ends of the conveying mechanism 20. For another example, the conveying mechanism 20 adopts an annular conveying line body, and the loading position and the conveying position are arranged at different positions of the annular conveying line body. The fixture 30 is specifically designed according to the structural form of the product to be coded.

[0027] When in use, the fixture 30 is fixedly mounted on the conveying mechanism 20 so as to be transferred between the loading position and the coding position as the conveying mechanism 20 operates. When the conveying mechanism 20 conveys the fixture 30 to the loading position, the material is loaded manually or by a robot; after loading, the conveying mechanism 20 operates to convey the product to be coded placed on the fixture 30 to the coding position, and the coding mechanism 40 performs the coding operation. The coded product is transported by the conveying mechanism 20 back to the loading position for unloading, and then loaded again, thereby performing the coding operation on the product in a reciprocating cycle.

[0028] The battery automatic coding device provided in the embodiment of the present invention switches the position of the fixture 30 by means of the conveying mechanism 20, so that the coding mechanism 40 performs coding operation on the product to be coded clamped by the fixture 30. The entire device is fully automated except for manual loading and unloading, with high coding efficiency, reduced manual participation, and avoidance of the influence of manual operation on coding quality, which helps to improve coding quality.

[0029] Among them, Figure 1 and Figure 2 As shown, the operating table 10 adopts a cabinet, and the top plate of the cabinet is used as the installation table surface, and the conveying mechanism 20 and the coding mechanism 40 are both installed on the top plate of the cabinet. The cabinet is equipped with opening and closing doors on the front, back, left and right sides, and the inside of the cabinet is used to lay the air path and circuit structure. Among them, a file bag storage slot is constructed on the inner side of the front door of the cabinet, which is convenient for the staff to store documents such as the workstation operation specifications. The top plate of the cabinet is provided with a through hole, through which the air supply pipeline and wires and cables pass. In order to facilitate movement, a pulley is installed at the bottom of the operating table 10, and the number of pulleys is four. The four pulleys are arranged at the four corners of the square operating table 10. A foot cup 12 is also installed at the bottom of the operating table 10, and the foot cup 12 is located on the outside of the pulley. The four foot cups 12 cooperate with each other to support and position the entire battery automatic coding device after it moves into place.

[0030] like Figure 3As shown, the battery automatic coding device in the embodiment of the present invention further includes a machine cover 50, which is fixedly mounted on the operating table 10. The conveying mechanism 20 is a linear guide rail, which can be a screw guide rail or a linear module. Figure 3 As shown, in order to ensure smooth operation, an auxiliary rail 21 is arranged in parallel on one side of the linear module or the screw guide rail. Taking the linear module as an example, the slide on the linear module is relatively small, and the jig 30 with four battery cells is relatively wide. The jig 30 is easy to fall sideways only by sliding the slide back and forth. The additional auxiliary rail 21 can balance the jig 30 and improve the smoothness of transportation. One end of the linear guide is located inside the hood 50 as a coding position, and the other end is located outside the hood 50 as a loading position. It should be noted that the coding position and the loading position can be located at the end of the linear guide, or at any other position within the travel range of the linear guide, and this embodiment of the present invention does not specifically limit this. The hood 50 is provided with a door body corresponding to the position of the linear guide and an automatic lifting door is installed at the door body. The jig 30 is installed on the linear guide rail and moves under the action of the linear guide rail. When the jig 30 moves to the door of the hood 50, the automatic lifting door opens, and the jig 30 is transported from the hood 50 to the end of the conveying mechanism 20 outside the hood 50, which is convenient for manual loading and unloading operations outside the hood 50. The coding mechanism 40 is installed on the end of the linear guide rail inside the hood 50.

[0031] On the basis of the above embodiment, the coding mechanism 40 can be fixedly installed on the operating table 10 or slidably installed on the operating table 10. The number and installation method of the coding mechanism 40 are selected according to the number of marking machines in the coding mechanism 40, the number of products to be coded positioned in the fixture 30, and the number of conveying mechanisms 20. For example, if there is one product to be coded positioned in the fixture 30 and there is one conveying mechanism 20, then one marking machine can be set. At this time, the coding mechanism 40 can be fixedly installed at the coding position of the operating table 10. For another example, if there is one product to be coded positioned in the fixture 30 and there are multiple conveying mechanisms 20, then one movable marking machine is required or multiple marking machines are fixedly installed corresponding to multiple conveying mechanisms 20. For another example, if multiple products to be coded are positioned and installed in the fixture 30, and there is only one conveying mechanism 20, a movable marking machine is required to be provided to code different products to be coded in the fixture 30, and the coding mechanism 40 can be slidably installed on the operating table 10; in addition, multiple marking machines can be provided, and the coding mechanism 40 can be fixed on the operating table 10. Of course, there are other combinations, which will not be described in detail in the embodiment of the present invention.

[0032] It should be noted that the conveying mechanism 20 can also be a circular conveying line body. In this case, the coding mechanism 40 can be fixedly installed on the operating table 10, and the product to be coded clamped by the fixture 30 on the conveying mechanism 20 is coded by means of the stepping of the circular conveying line body. A part of the arc of the circular conveying line body is located outside the machine cover 50, and most of the arc is located inside the machine cover 50. The coding mechanism 40 is located inside the machine cover 50 and can be located inside or outside the circumference of the circular conveying line body. Two or more fixtures 30 can be arranged on the circular conveying line body. Taking two as an example, when the product to be coded on one of the fixtures 30 is being coded, the other fixture 30 is in the loading position for loading and unloading.

[0033] When two or more linear guides are provided, the multiple linear guides are provided in parallel, and a partition is fixedly installed on the operating table 10, and the partition is arranged between two adjacent linear guides to prevent the slag generated by the coding from splashing and affecting other linear guides when the tooling fixture 30 on one of the linear guides is in the coding position for coding operation. In the embodiment of the present invention, the partition provides a relatively closed processing environment for each linear guide to improve the processing quality.

[0034] like Figure 4 As shown, the coding mechanism 40 includes a base 41 and a coding machine 42, and the base 41 is fixedly or slidably installed on the operating table 10. The coding machine 42 is fixedly or liftably installed on the top of the base 41 and suspended above the conveying mechanism 20. When the base 41 is lifted and installed, a slide groove is provided on the base 41, and a mounting seat 44 adapted thereto is installed on the slide groove. The coding machine 42 is fixedly installed on the mounting seat 44. At the beginning of the device debugging or after the processing battery cell model is changed, the position of the coding machine 42 can be adjusted by means of a cylinder or a manual adjustment wheel. When adjusted in place, the position of the code scanner 42 is fixed relative to the base 41 to ensure the consistency of the coding position of the battery cell of the same model. At the same time, in order to facilitate the adjustment of the position of the coding machine 42 along the conveying direction of the linear guide rail, a slide groove extending along the conveying direction of the linear guide rail is also provided on the mounting seat 44, and the coding machine 42 can be slidably installed in the slide groove. This allows the coding machine 42 to move in the height direction and the linear guide conveying direction, making it easier to debug and meeting the coding requirements of battery shells of different models. Figure 1 , Figure 2 and Figure 4As shown, taking the linear guide rail as an example, when the conveying mechanism 20 conveys the product to be coded held by the fixture 30 to the coding position, the coding machine 42 is located above the product to be coded. A detection sensor is also installed on the operating table 10, which is used to detect whether the product to be coded in the fixture 30 is delivered to the coding position. For example, a detection mounting plate 35 is fixedly installed on the operating table 10, and the detection mounting plate 35 can be an I-shaped plate, and the detection sensor is installed on the horizontal plate of the I-shaped plate. When the conveying mechanism 20 transfers the fixture 30 to the coding position, the detection sensor is triggered, the conveying mechanism 20 stops running according to the trigger signal, and the coding mechanism 40 starts the coding operation according to the trigger signal. When there are two linear guide rails, each linear guide rail is respectively installed with an I-shaped plate at one end located in the machine cover 50, and the detection sensor is installed on the I-shaped plate. When the conveying mechanism 20 is a circular conveying line body, the detection sensor can be set on the inner or outer side of the line body, as long as it can detect whether the position of the product to be coded is in place.

[0035] like Figure 5 and Figure 6 As shown, there is only one coding mechanism 40, and multiple products to be coded are positioned and installed on the fixture 30. For this purpose, a linear module 43 is fixedly installed on the operating table 10, and the base 41 is fixedly installed on the moving slide of the linear module 43, so that the mobile coding machine 42 can code different products to be coded in different lines and the same fixture 30. Preferably, as Figure 1 and Figure 2 As shown, the moving direction of the linear module 43 is perpendicular to the moving direction of the linear guide rail. Of course, linear modules 43 with other moving directions can also be used.

[0036] In addition, if Figure 1 and Figure 2 As shown, the battery automatic coding device provided by the embodiment of the present invention further includes a code scanning mechanism 60 for detecting the coding quality of the coding mechanism 40. The code scanning mechanism 60 is fixedly connected to the coding mechanism 40 and moves synchronously with respect to the operating table. Figure 4 As shown, the code scanning mechanism 60 includes a bracket 61, a code scanner 62 and a smoking pipe fixing member 63. The bracket 61 is fixedly connected to the base 41. The bracket 61 includes a crossbar and a vertical bar. One end of the vertical bar is fixedly connected to the base 41, and the other end of the vertical bar is fixedly connected to the crossbar. The extension direction of the crossbar is parallel to the sliding direction of the linear module 43. Two connecting rods are fixedly installed on the crossbar through a clamp, and the end of one of the connecting rods is fixedly installed with the code scanner 62, and the end of the other connecting rod is installed with the smoking pipe fixing member 63. The smoking pipe is fixedly installed on the bracket 61 through the smoking pipe fixing member 63. When the coding operation is performed, the slag generated by the coding is discharged from the entire device with the help of the smoking pipe. At the same time, after the coding is completed, the coding effect is detected with the help of the code scanner 62, and the uncoded or defective products are found in time.

[0037] When coding different products to be coded, different structural forms of fixtures 30 can be selected. For example, when coding the shell of a cylindrical battery cell, Figure 5 As shown, the jig 30 includes a base 31, and a plurality of grooves 32 are provided on the base 31. The grooves 32 are adapted to the outer shell shape of the cylindrical battery, and the extension direction of the grooves 32 is consistent with the conveying direction of the linear guide. Multiple shells can be clamped with the aid of a jig 30. Among them, the groove 32 can be a V-shaped groove. When it is a V-shaped groove, the shell is positioned with the help of two inclined surfaces of the V-shaped groove to prevent the shell from shaking. Of course, it can also be a trapezoidal groove, as long as there are two inclined surfaces in the groove body to position the shell. In addition, the groove 32 can also be an arc groove, and the curvature of the arc groove is adapted to the outer shape of the shell.

[0038] For example, when coding the end cap of a cylindrical battery cell, Figure 7 As shown, the battery automatic coding device also includes a pre-pressing mechanism 70 fixedly mounted on the operating table 10, and the pre-pressing mechanism 70 includes a pressing plate 71, as shown in FIG. Figure 6 As shown, the fixture 30 includes a seat 31, a positioning plate 33 and a driving member 34. The positioning plate 33 is provided with a groove 32 for accommodating the end cap. The driving member 34 is fixedly installed on the seat 31. The driving end of the driving member 34 is connected to the positioning plate 33 to drive the positioning plate 33 to contact the pressure plate 71. Among them, the driving member 34 adopts a driving cylinder. The positioning plate 33 can be a plate body with multiple grooves 32 or a plate body with only one groove 32. When multiple grooves 32 are provided, a positioning plate 33 and a driving member 34 are installed on the seat 31 to place multiple end caps; when only one groove 32 is provided, multiple positioning plates 33 can be installed on the seat 31, and each positioning plate 33 is connected to a driving member 34, which is convenient for splicing and assembly as needed. In order to monitor whether the fixture 30 is moved to the position, limiters are respectively set at both ends of the linear guide rail. When the seat 31 of the fixture 30 touches the limiter, it stops moving and is regarded as reaching the loading position or coding position.

[0039] like Figure 7 As shown, the pre-pressing mechanism 70 includes a column 72 and a pressing plate 71 mounted on the column 72. The column 72 is fixedly mounted on the operating table 10. The pressing plate 71 spans over two linear guide rails and is located above the two linear guide rails. When the fixture 30 is moved to the coding position, the driving member 34 drives the positioning plate 33 to move upward until it abuts against the pressing plate 71. A through hole is provided at the position of the pressing plate 71 corresponding to the product to be coded below. A mounting plate 73 is fixedly mounted on one side of the pressing plate 71. An optical fiber sensor is installed on the mounting plate 73 to detect whether there is material. When material is found, the coding machine 42 starts the coding operation.

[0040] In addition, based on the safety consideration of manual loading and unloading, a protective grating is installed on the door of the hood 50. When the worker triggers the protective grating by mistake, the entire device stops running. As shown in the figure, a display screen 51 is rotatably installed on one side of the hood 50, and an operating machine 52 is rotatably installed on the other side of the hood 50. The display screen 51 is used to display the operating status parameters of the entire device, which is convenient for workers to monitor the operating status of the device; the operating machine 52 is used to display the operating interface of the entire device and input control instructions through a hidden keyboard.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
