Description

Technical Field

[0001] This application relates to the technical field of battery fixtures, and in particular to a battery fixture. Background Technology

[0002] Battery jigs are specialized tools or equipment used in the battery manufacturing and testing process to improve production efficiency and ensure product quality and consistency. The design and application of jigs are wide-ranging, covering multiple key steps from battery assembly to performance testing. During battery assembly, jigs are used to precisely position and fix battery cells such as cells to ensure that the components can be accurately aligned.

[0003] The existing announcement number is CN222059140U, entitled "A Welding and Positioning Fixture for Battery Module Connecting Pieces." It includes a positioning end and a fixing end. The positioning end is located on the upper end of the battery module and has a positioning groove adapted to the shape of the connecting piece. The fixing end is fixedly connected to the positioning end and surrounds the battery module. The fixing end and positioning end are placed together on the battery module, and the positioning groove is used to position the connecting piece. This device can achieve precise positioning and fixing of the connecting piece, thereby improving the welding quality and service life of the battery module.

[0004] However, when using battery fixtures to limit and support battery cells, the fixed size of the positioning fixture can only position battery cells of a single size, resulting in a limited range of battery cells that the battery fixture can support and position. To support battery cells of different sizes, it is necessary to prepare fixtures of different sizes, which in turn increases the cost of preparing battery fixtures. Utility Model Content

[0005] In order to overcome the limitations of existing positioning fixtures which are fixed in size and can only position battery cells of a single size, resulting in a limited range of battery cells that can be positioned by the fixture, and the need to prepare fixtures of different sizes to support battery cells of different sizes, which increases the cost of preparing battery fixtures, this application provides a battery fixture.

[0006] The battery fixture provided in this application adopts the following technical solution:

[0007] A battery fixture includes a support, a clamping frame, clamping components, and a connector. The upper part of the support is horizontally provided with a clamping frame, and two clamping frames are horizontally symmetrically arranged. The lower parts of the two clamping frames are rotatably connected to the top of the support. Sliding frames are symmetrically fixed on both sides of the clamping frame, and multiple clamping components are horizontally slidably assembled between the sliding frames on both sides of the clamping frame. A sliding plate is horizontally slidably assembled between the sliding frames on both sides of the clamping frame, and an adjusting screw is horizontally rotatably connected to one side of the clamping frame. A screw hole plate is horizontally fixed to one end of the sliding plate, and the screw hole plate and the adjusting screw are threaded through each other. A fixing plate is vertically fixed on the upper and lower horizontal end faces of the two clamping frames, and a connector is horizontally fixedly installed on the fixing plate.

[0008] By adopting the above technical solution, the distance between the two clamping frames is first adjusted vertically according to the overall height of the battery cell. This vertical adjustment facilitates the application of the overall height of the battery cell. Then, multiple battery cells are respectively placed between the clamping parts of the two clamping frames. The adjusting screw on one side of the clamping frame is started to rotate, and the thread drives the sliding plate to slide horizontally in the middle of the clamping frame. The sliding plate is used to squeeze and clamp multiple battery cells to maintain stability during electrical welding. Then, the terminals of multiple battery cells are pressed against the connector, which facilitates the flexibility of welding multiple battery cells later.

[0009] Optionally, the support includes a fixed frame and a rod seat. The fixed frame is fixedly connected by a fixing screw, and a sleeve and a screw cylinder are vertically fixed on the top surface of the fixed frame. The bottom slide rod of the rod seat is vertically slidably assembled in the sleeve, and a support screw is vertically rotatably connected to the bottom surface of the rod seat, and the support screw is threadedly assembled in the screw cylinder.

[0010] By adopting the above technical solution, the fixing frame is fixedly connected by fixing screws during use. In later use, according to the height requirements of the support, the support screw at the bottom of the rotating rod seat moves vertically in the screw cylinder, and the slide rod at the bottom of the vertical guide rod seat slides vertically in the sleeve. The rod seat on the vertical adjustment fixing frame moves vertically, which facilitates the vertical change of the support height and meets the adjustment requirements of cell welding.

[0011] Optionally, a rotating rod is horizontally fixed at the top of the rod holder, and the rotating rod of the rod holder is rotatably connected to the side end face of the clamping frame on the lower side of the two clamping frames.

[0012] By adopting the above technical solution, when welding the double-sided battery cell's contact end and contact end piece, rotating the two clamping frames at the top of the rod seat allows for easy switching of the battery cell's contact end for welding, thus improving the effectiveness of adjusting the welding at the battery cell's end.

[0013] Optionally, the clamping component includes a slide bar, which is horizontally slidably assembled in the slide frames on both sides of the clamping frame, and multiple elastic frames are horizontally and vertically fixed on the vertical end faces of both sides of the slide bar.

[0014] By adopting the above technical solution, the slider is horizontally slidably assembled in the sliding frames on both sides of the clamping frame, which facilitates the sliding of the slider in the sliding frames on both sides of the clamping frame according to the outer diameter of the battery cell, and facilitates the stability of horizontal movement, squeezing and clamping multiple battery cells.

[0015] Optionally, multiple elastic frames on both sides of the slider are vertically fixed with clamping strips, and soft pads are fixed on the vertical end faces of the clamping strips.

[0016] By adopting the above technical solution, the clamping bars on both sides of the slide bar are supported by multiple elastic frame deformation clamping bars. The deformation force of the multiple elastic frames is used to squeeze the clamping bars to maintain the stability of the battery cell. At the same time, the setting of the soft pad helps to ensure the stability of the battery cell clamping, further ensuring the stability of the battery cell clamping.

[0017] Optionally, the connector includes a lifting slide frame, a screw hole seat is fixed on one vertical end face of the lifting slide frame, and the screw hole seat is fixed to the fixing plate by bolts, and multiple slide tracks are horizontally opened on the lifting slide frame.

[0018] By adopting the above technical solution, the screw hole seat at the end of the lifting slide frame is fixed to the fixing plate by bolts, which completes the stability of the connector assembly on the outside of the clamping frame. At the same time, the lifting slide frame has multiple horizontally through-cut slides for effective horizontal clamping and squeezing of multiple battery cells.

[0019] Optionally, multiple perforated blocks are evenly and horizontally assembled in the multiple slides of the lifting frame, and a through hole is opened in the middle of the multiple perforated blocks.

[0020] By adopting the above technical solution, the sliding block in the slide rail of the lifting frame is laterally slidable to adjust the size of the block to match the battery cell. Then, the through hole on the block is used for the battery cell terminal to pass through the through hole and guide the battery cell terminal to be welded.

[0021] Optionally, a slide cylinder and a screw tube are vertically fixed on the lower clamping frame of the two clamping frames, and a guide rod is vertically fixed on the upper clamping frame of the two clamping frames. The guide rod is vertically slidably assembled in the slide cylinder, and an opening and closing screw is vertically rotatably connected on the upper clamping frame of the two clamping frames. The opening and closing screw is threadedly assembled in the screw tube.

[0022] By adopting the above technical solution, the distance between the two clamping frames can be adjusted vertically according to the overall height of the battery cell during use. When the distance between the two clamping frames is adjusted vertically to accommodate the overall height of the battery cell, the rotating screw tube rotates on the clamping frame, and the thread drives the opening and closing screw to move vertically in the screw tube, pushing the guide rod on the two clamping frames to slide vertically in the slide cylinder, so as to facilitate the vertical adjustment of the distance between the two clamping frames to accommodate the overall height of the battery cell.

[0023] In summary, this application includes at least one of the following beneficial technical effects: First, based on the overall height of the battery cell, the distance between the two clamping frames is adjusted vertically to accommodate the overall height of the battery cell. Then, multiple battery cells are respectively placed between the clamping parts in the two clamping frames. The adjusting screw on one side of the clamping frame is then rotated, and the threaded drive slide plate slides horizontally in the middle of the clamping frame. The slide plate's sliding pressure clamps multiple battery cells, maintaining stability during electrical welding. Then, the terminals of the multiple battery cells are pressed against the connector, ensuring flexibility for subsequent welding of the multiple battery cells. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a battery fixture. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A battery fixture includes a support 1, a clamping frame 2, clamping components 3, and a connector 4. The upper part of the support 1 is horizontally provided with a clamping frame 2, and two clamping frames 2 are horizontally symmetrically arranged. The lower parts of the two clamping frames 2 are rotatably connected to the top of the support 1. Sliding frames 21 are symmetrically fixed on both sides of the clamping frame 2, and multiple clamping components 3 are horizontally slidably assembled between the sliding frames 21 on both sides of the clamping frame 2. A sliding plate 22 is horizontally slidably assembled between the sliding frames 21 on both sides of the clamping frame 2, and an adjusting screw 23 is horizontally rotatably connected to one side of the clamping frame 2. A screw hole plate 221 is horizontally fixed to one end of the sliding plate 22, and the screw hole plate 221 and the adjusting screw 23 are threaded through each other. A fixing plate 24 is vertically fixed on the upper and lower horizontal end faces of the two clamping frames 2, and a connector 4 is horizontally fixedly installed on the fixing plate 24.

[0032] By adopting the above technical solution, in use, the distance between the two clamping frames 2 is first adjusted vertically according to the overall height of the battery cell. This vertical adjustment of the distance between the two clamping frames 2 is convenient for adapting to the overall height of the battery cell. Then, multiple battery cells are respectively placed between the clamping parts 3 in the two clamping frames 2. The adjusting screw 23 on one side of the clamping frame 2 is started to rotate, and the thread drives the sliding plate 22 to slide horizontally in the middle of the clamping frame 2. The sliding plate 22 is used to squeeze and clamp multiple battery cells to maintain stability during electrical welding. Then, the terminals of multiple battery cells are pressed against the connector 4, which facilitates the flexibility of welding multiple battery cells in the later stage.

[0033] Reference Figure 1 and Figure 2 The support component 1 includes a fixed frame 11 and a rod seat 12. The fixed frame 11 is fixedly connected by a fixing screw 113, and a sleeve 111 and a screw barrel 112 are vertically fixed on the top surface of the fixed frame 11. The bottom sliding rod of the rod seat 12 is vertically slidably assembled in the sleeve 111, and a support screw 121 is vertically rotatably connected to the bottom surface of the rod seat 12, and the support screw 121 is threadedly assembled in the screw barrel 112. In use, the fixed frame 11 is fixedly connected by the fixing screw 113. In later use, according to the height requirements of the support, the support screw 121 at the bottom of the rod seat 12 is rotated to move vertically in the screw barrel 112, and the sliding rod at the bottom of the vertical guide rod seat 12 slides vertically in the sleeve 111. The vertical adjustment of the rod seat 12 on the fixed frame 11 allows for vertical changes in the support height, meeting the adjustment requirements for cell welding. A rotating rod is horizontally fixed at the top of the rod base 12, and the rotating rod of the rod base 12 is rotatably connected to the side end face of the two clamping frames 2. When welding the double-sided battery cell terminal and terminal piece during use, rotating the two clamping frames 2 causes the rotating rod at the top of the rod base 12 to rotate and deflect, which facilitates switching the battery cell terminal for welding and improves the effectiveness of adjusting the welding at the battery cell end.

[0034] Reference Figure 2 , Figure 3 and Figure 4The clamping component 3 includes a slide bar 31, which is horizontally slidably assembled in the slide frames 21 on both sides of the clamping frame 2. Multiple elastic frames 32 are horizontally and vertically fixed to the vertical end faces of both sides of the slide bar 31. The horizontal slidability of the slide bar 31 within the slide frames 21 on both sides of the clamping frame 2 facilitates sliding of the slide bar 31 within the slide frames 21 on both sides of the clamping frame 2 according to the outer diameter of the battery cell, thus ensuring the stability of horizontally moving and squeezing multiple battery cells. Clamping strips 33 are vertically fixed to the outer sides of the multiple elastic frames 32 on both sides of the slide bar 31, and soft pads 34 are fixed to the outer vertical end faces of the clamping strips 33. The clamping strips 33 on both sides of the slide bar 31 are supported by the deformation of the multiple elastic frames 32. The deformation force of the multiple elastic frames 32 is used to squeeze the clamping strips 33 to maintain the stability of the battery cell. Simultaneously, the soft pads 34 further ensure the stability of the battery cell clamping.

[0035] Reference Figure 2 and Figure 5 The connector 4 includes a lifting slide frame 41. A screw hole seat 42 is fixed to one vertical end face of the lifting slide frame 41, and the screw hole seat 42 is fixed to the fixing plate 24 by bolts. Multiple horizontally extending slide tracks are formed on the lifting slide frame 41. The screw hole seat 42 at the end of the lifting slide frame 41 is fixed to the fixing plate 24 by bolts, ensuring the stability of the connector 4 assembled outside the clamping frame 2. Simultaneously, the multiple horizontally extending slide tracks of the lifting slide frame 41 effectively clamp and compress multiple battery cells. Multiple hole blocks 43 are evenly and horizontally slidably assembled in the multiple slide tracks of the lifting slide frame 41, and through holes are formed in the middle of each hole block 43. The sliding hole blocks 43 in the slide tracks of the lifting slide frame 41 are used to adjust the size of the hole blocks 43 to match the battery cells. The through holes on the hole blocks 43 are used for the through holes of the battery cell terminals, guiding the battery cell terminals for welding.

[0036] Reference Figure 1 and Figure 5 A sliding cylinder 5 and a screw tube 6 are vertically fixed on the lower clamping frame 2, and a guide rod 7 is vertically fixed on the upper clamping frame 2. The guide rod 7 is vertically slidably assembled in the sliding cylinder 5, and an opening and closing screw 8 is vertically rotatably connected to the upper clamping frame 2. The opening and closing screw 8 is threadedly assembled in the screw tube 6. During use, the distance between the two clamping frames 2 is adjusted vertically according to the overall height of the battery cell. When adjusting the distance between the two clamping frames 2 to suit the overall height of the battery cell, the screw tube 6 is rotated on the clamping frame 2, and the screw drive the opening and closing screw 8 to move vertically in the screw tube 6, pushing the guide rod 7 on the two clamping frames 2 to slide vertically in the sliding cylinder 5, so as to facilitate the vertical sliding adjustment of the distance between the two clamping frames 2 to suit the overall height of the battery cell.

[0037] The implementation principle of a battery fixture according to an embodiment of this application is as follows: First, based on the overall height of the battery cell, the distance between the two clamping frames 2 is adjusted vertically to accommodate the overall height of the battery cell. The rotating screw tube 6 rotates on the clamping frame 2, driving the opening and closing screw 8 to move vertically within the screw tube 6, pushing the guide rod 7 on the two clamping frames 2 to slide vertically within the slide cylinder 5. This facilitates vertical adjustment of the distance between the two clamping frames 2 to accommodate the overall height of the battery cell. Then, multiple battery cells are respectively placed between the clamping members 3 in the two clamping frames 2. The adjusting screw 23 on one side of the clamping frame 2 is activated to rotate, driving the sliding plate 22 to slide horizontally within the clamping frame 2. The sliding plate 22 is used to slide and squeeze the multiple battery cells, and the clamping bars on both sides of the sliding strip 31... Multiple elastic frames 32 deform to support the clamping strip 33. The deformation force of the multiple elastic frames 32 is used to compress the clamping strip 33 to maintain the stability of the battery cell. At the same time, the soft pad 34 is set to ensure the stability of the battery cell clamping and maintain the stability during welding. Then, the screw hole seat 42 set at the end of the lifting slide frame 41 is fixed to the fixing plate 24 by bolts, which completes the stability of the connector 4 assembled on the outside of the clamping frame 2. At the same time, multiple slides are opened horizontally through the lifting slide frame 41 to effectively clamp and compress multiple battery cells. The sliding hole block 43 in the slide of the lifting slide frame 41 slides horizontally to adjust the size of the hole block 43 to match the battery cell. Then, the through hole on the hole block 43 is used for the battery cell terminal to pass through and guide the battery cell terminal to weld. Multiple battery cell terminals pass through and press against the connector 4.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
