Description

Technical Field

[0001] This utility model relates to the field of battery cell module technology, specifically to a secondary positioning device for an end plate and an insulating cover. Background Technology

[0002] End plates and insulating covers are common components of battery cell modules. After assembly, end plates or insulating covers need to be attached to both ends of the battery cell module, primarily for protection. The traditional method for attaching end plates and insulating covers involves manually placing them in a loading tray, followed by a robotic arm picking them up and attaching them to the battery cell module. However, the attachment of end plates and insulating covers requires precision, with positional tolerances typically controlled within ±0.5mm. Because the positions of the end plates and insulating covers in the loading tray are not fixed, the robotic arm cannot accurately position and pick them up, compromising the attachment accuracy. Therefore, developing a secondary positioning device that allows for secondary positioning of the end plates or insulating covers before the robotic arm picks them up and precisely attaches them to the battery cell module is of significant importance in this field.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solution of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and a preferred embodiment.

[0021] See Figures 1-4 This application provides a secondary positioning device for an end plate and an insulating cover, including a reference platform 10, an X-axis positioning mechanism 20 and a Y-axis positioning mechanism 30.

[0022] The reference platform 10 includes a support frame 11, a platform plate 12, a positioning platform 13, and a position detection switch 40. The platform plate 12 is supported above the support frame 11 and is used to mount the position detection switch 40, the X-axis positioning mechanism 20, the Y-axis positioning mechanism 30, and the positioning platform 13. The positioning platform 13 supports and positions the end plate or insulating cover; for ease of description, the end plate or insulating cover will be collectively referred to as the positioning component. The X-axis positioning mechanism 20 is located at one end of the positioning platform 13 and is used to position the positioning component in the X-axis direction. The Y-axis positioning mechanism 30 is located at the other end of the positioning platform 13 and is used to position the positioning component, already positioned in the X-axis direction, in the Y-axis direction, thereby achieving secondary positioning of the positioning end plate or insulating cover. The position detection switch 40 is used to detect whether a positioning component is placed on the positioning platform 13 before positioning.

[0023] In this embodiment, to reduce installation space, both the platform plate 12 and the positioning platform 13 are designed in an inclined state, with the platform surface of the positioning platform 13 parallel to the platform plate surface. The X-axis positioning mechanism 20 is located at the upper end of the platform plate 12, pushing the positioning component from top to bottom along the X-axis direction. This utilizes gravity to reduce the pushing load on the X-axis positioning mechanism 20. The X-axis direction can also be referred to as the front-to-back direction of the positioning platform 13. The Y-axis positioning mechanism 30 is located at the left end of the positioning platform 13, pushing the positioning component from left to right along the Y-axis direction. In other embodiments, if space permits, both the platform plate 12 and the positioning platform 13 can be designed in a horizontal state. In this embodiment, the X-axis positioning mechanism 20 matches the length of the positioning component, and the Y-axis positioning mechanism 30 matches the width of the positioning component. In other embodiments, the X-axis positioning mechanism 20 can match the width of the positioning component, and the Y-axis positioning mechanism 30 can match the length of the positioning component.

[0024] The positioning platform 13 is installed on the right side of the platform plate 12, and includes a table surface 131 and support legs. The table surface 131 is supported on the platform plate 12 by the support legs. The side of the table surface 131 is provided with X-direction reference seats 133 and Y-direction reference seats 132. In this embodiment, two X-direction reference seats 133 are provided on the lower side of the table surface 131, and five Y-direction reference seats 132 are provided on the right side of the table surface 131.

[0025] To reduce frictional resistance and facilitate the adhesion of the positioning components to the positioning platform 13, it is preferable to have several strip grooves formed on the surface of the positioning platform 13. For example, in this embodiment, several parallel strip grooves are formed along the X direction of the platform. To avoid interference and reduce the stroke of the positioning mechanism, it is preferable to have X-direction notches 134 and Y-direction notches 135 adapted to the push block of the positioning mechanism formed on the surface of the positioning platform 13. For ease of inspection, a detection port is also provided on the platform 131, and the detection switch 40 is installed in the detection port.

[0026] In this embodiment, the X-axis positioning mechanism 20 includes a first servo motor 21, a coupling 22, a fixed end support 23, a first lead screw nut 24, a floating end support 25, a first ball screw 26, a first linear slide rail 27, and an X-axis push block assembly 28. The first servo motor 21 is mounted on the lower side of the platform plate 12. The first ball screw 26 is rotatably mounted on the lower side of the platform plate 12 via the fixed end support 23 and the floating end support 25. The motor shaft of the first servo motor 21 is connected to the first ball screw 26 via the coupling 22. The first linear slide rail 27 is mounted parallel to the side of the ball screw 26. The first lead screw nut 24 is threadedly connected to the first ball screw 26 on one hand, and slidably connected to the first linear slide rail 27 via a slider on the other hand. Specifically, the first lead screw nut 24 and the slider can be connected via a first nut fixing plate.

[0027] The X-axis push block assembly 28 includes a push block fixing plate 281, a sliding column 283 slidably mounted on the lower end of the push block fixing plate 281 via a linear bearing 282 at one end, an X-axis push block 284 whose axis is fixed to the free end of the sliding column 283, and a spring (not shown in the figure) fitted on the sliding column 283. One end of the sliding column 283, equipped with the linear bearing, extends out of the push block fixing plate 281 and connects to a stop. The sliding column 283 slides along the X-axis under the constraint of the stop and the push block fixing plate 281. One end of the spring abuts against the push block fixing plate 281, and the other end abuts against the X-axis push block 284. The spring ensures that during positioning, the X-axis push block 284 can closely contact the positioning element, causing the other end of the positioning element to abut against the X-axis reference seat 133, thus improving X-axis positioning accuracy. The X-axis push block assembly 28 is fixedly mounted on the first nut fixing plate via its push block fixing plate 281. The X-axis push block 284 extends through an opening on the platform plate 12 into the X-axis notch 134.

[0028] In this embodiment, the Y-axis positioning mechanism 30 includes a second servo motor 31, a driving wheel 32, a synchronous belt 33, a driven wheel 34, a driving end support 35, a passive end support 351, a second ball screw 36, a second screw nut 37, a second linear slide rail 38, and a Y-axis push block assembly 39. The second servo motor 31 is mounted on the lower side of the platform plate 12. The second ball screw 36 is rotatably mounted on the upper side of the platform plate 12 along the Y-axis direction via the driving end support 35 and the passive end support 351. The second linear slide rail 38 is mounted parallel to one side of the second ball screw 36. The second servo motor 31 drives the second ball screw 36 to rotate through a synchronous belt transmission mechanism composed of the driving wheel 32, the synchronous belt 33, and the driven wheel 34. The second screw nut 37 is threadedly connected to the second ball screw 36 on one hand, and slidably connected to the second linear slide rail 38 on the other hand through a slider. Specifically, the second screw nut 37 and the slider can be connected through a second nut fixing plate.

[0029] The Y-axis push block assembly 39 includes an X-axis fixing plate 391 fixed along the X-axis direction to the second nut fixing plate, a positioning plate 392 slidably connected to the X-axis fixing plate 391 via three sliding shafts and linear bearings, three Y-axis push blocks 393 fixed side-by-side at intervals on the positioning plate 392, and three springs respectively fitted on the three sliding shafts and abutting against the positioning plate 392 and the Y-axis push blocks 393 at both ends. The springs function the same as those in the X-axis push block assembly 28. The Y-axis push block assembly 39 is fixedly mounted on the second nut fixing plate via its X-axis fixing plate 391, and the three Y-axis push blocks 393 extend into the three Y-axis notches 135 of the positioning platform 13.

[0030] In this embodiment, the X-axis positioning mechanism 20 and the Y-axis positioning mechanism 30 mainly adopt ball screw linear motion mechanisms. In other embodiments, other linear motion mechanisms such as helical pair transmission mechanisms and gear and rack transmission mechanisms may also be used.

[0031] The working method of this application is as follows:

[0032] 1. The robot picks up the positioning parts from the loading table, and after passing the adhesive tearing and adhesive tearing detection, places the positioning parts on the table surface of the positioning platform 13.

[0033] 2. Position detection switch 40, preferably a diffuse reflection switch, detects the positioning element;

[0034] 3. The first servo motor 21 starts, and the X-axis push block 284 pushes the positioning component to the X-axis reference seat 133 to complete the X-axis positioning;

[0035] 4. The second servo motor 31 starts, and the Y-axis push block 393 pushes the positioning component of the X-axis positioning to the Y-axis reference seat 132 to complete the Y-axis positioning.

[0036] 5. The secondary positioning action of the positioning component is completed, and it waits for the robot's suction cup to pick it up.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
