Description

Technical Field

[0001] This utility model relates to a straight-tooth adjustment and limiting mechanism for a compatible cell replacement stage, belonging to the field of power battery production lines. Background Technology

[0002] Currently, most power battery production lines adopt a modular cell replacement platform design. This platform has several through holes on its substrate, and bolts are used to fix the limiting blocks to the substrate. When changing the cell model, the bolts are removed to completely remove the limiting blocks from the substrate. Then, according to the size of the cell, the bolts are passed through the corresponding through holes, and the bolts and the limiting blocks are matched to fix the limiting blocks in the corresponding positions. This allows for the adjustment of the distance between the limiting blocks so that the space between the limiting blocks can be adapted to the cell model.

[0003] Existing technology uses bolts to install and remove the limiting blocks. When adjusting the limiting blocks, they are completely removed from the substrate, and then bolts are inserted into appropriate through holes to fix the limiting blocks to the substrate. When switching cell models, the adjustment time for the limiting blocks on the cell replacement table is relatively long, taking about 45 minutes each time under standard operating conditions. This seriously restricts the overall efficiency of the power battery production line equipment. Existing technology is limited by the number of through holes on the substrate and can generally only be compatible with 3-5 types of cells. Therefore, the number of cell replacement tables of different specifications required is large, leading to a surge in warehousing and management costs. Summary of the Invention

[0004] The purpose of this invention is to provide a straight-tooth adjustment limit mechanism for a compatible cell replacement platform, thereby solving the technical defect of low adjustment efficiency of the limit mechanism in the existing cell replacement platform, which leads to low overall efficiency of the power battery production line equipment.

[0005] To solve the above problems, the technical solution adopted by this utility model is: a straight-tooth adjustment and limiting mechanism for a compatible battery cell replacement stage, including a substrate assembly, an X-axis pitch-changing assembly, and an XY-axis pitch-changing assembly. The X-axis pitch-changing assembly includes multiple reference positioning blocks I spaced apart along the X-axis direction at one end of the substrate assembly. The XY-axis pitch-changing assembly includes a base plate II disposed on the substrate assembly and movable along the X-axis direction. A Y-axis rack assembly is disposed between the base plate II and the substrate assembly. On the base plate II, spaced apart along the X-axis direction, are fixedly arranged blocks respectively opposite to the reference positioning blocks I. The base plate 2 has a corresponding reference positioning block 2, and a movable block 2 is provided on the side of the base plate 2 away from the reference positioning block 1. An X-axis rack assembly 2 is provided between the movable block 2 and the base plate 2 along the X-axis. Multiple movable positioning blocks 2 corresponding to the reference positioning block 2 are provided on the movable block 2. The movable positioning blocks 2 can move synchronously with the movable block 2 along the X-axis and are used to cooperate with the reference positioning block 2 and the reference positioning block 1 to position the battery cell in the X-axis direction. The base plate 2 moves along the Y-axis direction, and the movable positioning blocks 2, the reference positioning blocks 2 and the reference positioning blocks 1 cooperate to position the battery cell in the Y-axis direction. This invention allows for adjustment of the moving block II in the X-axis direction by setting an X-axis rack assembly II, and for adjustment of the moving block II in the Y-axis direction by setting a Y-axis rack assembly II. During adjustment, it is not necessary to remove the X-axis pitch control assembly and the XY-axis pitch control assembly from the base plate assembly. Therefore, this invention has high adjustment efficiency. When used in power battery production line equipment, it can improve the overall efficiency of the power battery equipment. This invention does not require opening holes on the base plate assembly to fix the reference positioning block I, the moving positioning block II, and the reference positioning block II. This invention has a wider adjustment range and can adapt to more cell specifications. Therefore, the required quantity of this invention is small, which can reduce warehousing and management costs.

[0006] As a further improvement of this invention, a scale is provided on the substrate assembly along the Y-axis direction. The scale is used to determine the distance the base plate II moves on the substrate assembly. By providing the scale, this invention allows the determination of the distance the base plate II moves on the substrate assembly, thereby determining the distance the XY-axis pitch-changing assembly is adjusted toward or away from the X-axis pitch-changing assembly.

[0007] As a further improvement of this utility model, it also includes a base plate I, a movable positioning block I, and a movable block I. The base plate I is fixed on the base plate assembly, the reference positioning block I is fixed on the base plate I, and the movable block I is disposed on the side of the base plate I away from the XY axis pitch-changing assembly. An X-axis rack assembly I is disposed between the movable block I and the base plate I. The movable positioning block I is fixed on the movable block I and corresponds to the reference positioning block I. By setting the base plate I, the movable positioning block I, and the movable block I, the distance between the movable positioning block I of the X-axis pitch-changing assembly and the reference positioning block I can be adjusted, thereby allowing for simultaneous positioning in both the X and Y axes from both ends of the battery during use, improving the accuracy of cell positioning.

[0008] As a further improvement of this utility model, the base plate II is provided with a Y-axis adjustment mechanism for adjusting the engagement and disengagement of the Y-axis rack assembly, the moving block II is provided with an X-axis adjustment mechanism II for adjusting the engagement and disengagement of the X-axis rack assembly II, and the moving block I is provided with an X-axis adjustment mechanism I for adjusting the engagement and disengagement of the X-axis rack assembly I. The Y-axis adjustment mechanism, X-axis adjustment mechanism II, and X-axis adjustment mechanism I have the same structure. This utility model, by providing the Y-axis adjustment mechanism, X-axis adjustment mechanism II, and X-axis adjustment mechanism I, makes adjustment of this utility model more convenient.

[0009] As a further improvement of this utility model, the Y-axis adjustment mechanism includes an adjusting rod, a spring pressure plate, and a spring. The spring pressure plate is fixed on the base plate II. The adjusting rod passes through the spring pressure plate and the base plate II, and its bottom end is connected to the Y-axis rack assembly. The spring is sleeved on the adjusting rod, with its bottom end pressing against the Y-axis rack assembly and its upper end abutting against the spring pressure plate. Pulling the adjusting rod upward pulls the Y-axis rack assembly to disengage it and simultaneously compresses the spring. Releasing the adjusting rod causes the spring to extend and push the rod downward, causing the Y-axis rack assembly to engage. In this utility model, the adjusting rod of the Y-axis adjustment mechanism can pull the Y-axis rack assembly to disengage its rack, while the spring, after the tension of the adjusting rod disappears, can push the Y-axis rack assembly downward to engage the rack.

[0010] As a further improvement of this utility model, the Y-axis rack assembly includes an upward Y-axis rack and a downward Y-axis rack. The downward Y-axis rack is fixed on the base plate assembly. The upward Y-axis rack is fixedly connected to the adjusting rod of the Y-axis adjusting mechanism. When the adjusting rod is pulled upward, the upward Y-axis rack disengages from the downward Y-axis rack, allowing the base plate II to move along the Y-axis. When the adjusting rod is released, the upward Y-axis rack moves downward and engages with the downward Y-axis rack, preventing the base plate II from moving along the Y-axis. The X-axis rack assembly II includes an upward X-axis rack II and a downward X-axis rack II. The downward X-axis rack II is fixed on the base plate II. The upward X-axis rack II is fixedly connected to the adjusting rod of the X-axis adjusting mechanism II. When the adjusting rod is pulled upward, the downward X-axis rack disengages from the downward Y-axis rack, allowing the base plate II to move along the Y-axis. When the upward rack II disengages from the downward rack II, the moving block II can move along the X-axis. When the adjusting rod is released, the upward rack II moves downward and engages with the downward rack II, preventing the moving block II from moving along the X-axis. The X-axis rack assembly I includes an upward rack I and a downward rack I. The downward rack II is fixed on the base plate I. The upward rack I is fixedly connected to the adjusting rod of the X-axis adjusting mechanism I. When the adjusting rod is pulled upward to disengage the upward rack I from the downward rack I, the moving block I can move along the X-axis. When the adjusting rod is released, the upward rack I moves downward and engages with the downward rack I, preventing the moving block I from moving along the X-axis. This invention can achieve horizontal limitation or movement of the corresponding structure through the engagement and disengagement of the two racks.

[0011] As a further improvement of this utility model, the base plate assembly is provided with two or more Y-axis guide rails along the Y-axis direction, and the bottom of the base plate II is provided with multiple Y-axis sliders, which slide in cooperation with the Y-axis guide rails. An X-axis guide rail II is provided on the base plate II along the X-axis direction, and a movable positioning block II is slidably mounted on the X-axis guide rail II. An X-axis guide rail I is provided on the base plate I along the X-axis direction, and a movable positioning block I is slidably mounted on the X-axis guide rail I. This utility model, by providing guide rails, facilitates the movement of the base plate II, movable positioning block II, and movable positioning block I.

[0012] As a further improvement of this utility model, Y-axis rack assemblies are provided at both ends of the base plate II and between the base plate II and the base plate assembly. A Y-axis adjustment mechanism is provided at each end of the base plate II, respectively used to adjust the engagement and disengagement of the two Y-axis rack assemblies. With Y-axis rack assemblies at both ends of the base plate II, this utility model provides better force distribution and greater overall stability when the base plate II is not adjusted.

[0013] As a further improvement of this invention, Y-axis through-beam sensors, the same number as the reference positioning blocks I, are spaced along the X-axis on the substrate assembly. The positions of the Y-axis through-beam sensors in the X-axis direction are adjustable. These sensors are used for in-situ detection of the battery cells. By using these Y-axis through-beam sensors, this invention can determine the presence of a battery cell at a corresponding location by observing whether the emitted light is blocked.

[0014] As a further improvement of this invention, X-direction through-beam sensors I are arranged on both sides of the substrate assembly near the X-axis pitch-changing assembly, and X-direction through-beam sensors II are arranged at both ends of the base plate II. X-direction through-beam sensors I and II respectively detect over-height of the battery cell from both ends. This invention, by setting X-direction through-beam sensors I and II, can detect whether the battery cell is over-height from both ends.

[0015] In summary, the beneficial effects of this utility model are: this utility model allows for quick product changeover without disassembling the limit block assembly during a single cell model switch, thereby improving the overall efficiency of the power battery production line; this utility model also reduces the number of differential chemical packages, thus lowering warehousing and management costs.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. For example... Figure 1 The spur gear adjustment and limiting mechanism of the compatible cell replacement stage shown includes a base plate assembly 1, an X-axis pitch variable assembly 2, and an XY-axis pitch variable assembly 3.

[0023] like Figure 1 and Figure 2 As shown, the X-axis pitch-changing assembly 2 includes multiple reference positioning blocks I4 that are equally spaced along the X-axis direction at one end of the substrate assembly 1. The reference positioning block I4 includes a lower cuboid support portion 401 and an upper L-shaped limiting portion 402. In use, the support portion 401 provides upward support to the battery cell from the bottom, while the limiting portion 402 can block one end of the battery cell from the X-axis direction and the Y-axis direction, thereby limiting the battery cell from one end.

[0024] like Figure 1 and Figure 2As shown, the XY-axis pitch-changing assembly 3 includes a base plate II5 disposed on the base plate assembly 1 and movable along the X-axis direction. The base plate II5 is a cuboid plate with its length direction aligned with the X-axis direction. A Y-axis rack assembly 6 is disposed between the base plate II5 and the base plate assembly 1. The racks of the Y-axis rack assembly 6 engage or disengage to fix the base plate II5 in the Y-axis direction or to move and adjust the base plate II5 in the Y-axis direction. Reference positioning blocks II7, corresponding to reference positioning blocks I4, are fixed at intervals along the X-axis direction on the base plate II5. That is, the number of reference positioning blocks II7 in this invention is equal to the number of reference positioning blocks I4, and each reference positioning block II7 has a corresponding reference positioning block I4 in the Y-axis direction. The shape of the reference positioning block I4 is the same as that of the reference positioning block II7, and the reference positioning blocks I4 and II7 are... The openings of the positioning parts 402 are opposite to each other. A movable block 28 is provided on the side of the base plate 25 away from the reference positioning block 14. The movable block 28 is cuboid in shape, and its length direction is the same as the X-axis direction. An X-axis rack assembly 29 is provided between the movable block 28 and the base plate 25. The racks of the X-axis rack assembly 29 mesh or disengage with each other to fix the movable block 28 on the base plate 25 or to move and adjust the movable block 28 on the base plate 25 along the X-axis direction. In this utility model, multiple movable positioning blocks 210 corresponding to the reference positioning block 27 are provided on the movable block 28. The number of movable positioning blocks 210 is equal to the number of reference positioning blocks 27, and one movable positioning block 210 is provided for each reference positioning block 27. The movable positioning blocks 210 can move synchronously with the movable block 28 along the X-axis direction to adjust the distance between the movable positioning blocks 210 and the reference positioning blocks 27.

[0025] The distance adjustment between the movable positioning block II10 and the reference positioning block II7 in this invention is used to limit the battery cell in the X-axis direction in cooperation with the reference positioning block I4. As the base plate II5 moves along the Y-axis, the movable positioning block II10 and the reference positioning block II7 can cooperate with the reference positioning block I4 to position the battery cell in the Y-axis direction. This invention can also provide a scale 11 along the Y-axis on the base plate assembly 1, which is used to determine the distance the base plate II5 moves on the base plate assembly 1.

[0026] like Figure 1 and Figure 3As shown, in order to better limit the position of the battery cell, the X-axis pitch-changing assembly 2 of this utility model is provided with a base plate I12, a movable positioning block I13, and a movable block I14. The base plate I12 is fixed on the base plate assembly 1, the reference positioning block I4 is fixed on the base plate I12, and the movable block I14 is located on the side of the base plate I12 away from the XY-axis pitch-changing assembly 3. An X-direction rack assembly I15 is provided between the movable block I14 and the base plate I12. The movable positioning block I13 is fixed on the movable block I14 and corresponds to the reference positioning block I4. The X-axis pitch-changing assembly 2 is the same as the XY-axis pitch-changing assembly 3, and the structure of the XY-axis pitch-changing assembly 3 can be referred to. Since the base plate I12 is directly fixed on the base plate assembly 1, the base plate I12 cannot move along the Y-axis direction on the base plate assembly 1. Therefore, the X-axis pitch-changing assembly 2 does not need to be provided with a Y-direction rack assembly 6.

[0027] like Figure 1 As shown, this utility model has a Y-axis adjustment mechanism 16 on the base plate II5 for adjusting the engagement and disengagement of the Y-axis rack assembly 6, an X-axis adjustment mechanism II17 on the moving block II8 for adjusting the engagement and disengagement of the X-axis rack assembly II9, and an X-axis adjustment mechanism I18 on the moving block I14 for adjusting the engagement and disengagement of the X-axis rack assembly I15. The Y-axis adjustment mechanism 16, the X-axis adjustment mechanism II17, and the X-axis adjustment mechanism I18 have the same structure.

[0028] The following section uses the Y-axis adjustment mechanism 16 as an example to describe its structure in detail. Figure 5 As shown, the Y-axis adjustment mechanism 16 includes an adjusting rod 19, a spring pressure plate 20, and a spring 21. The spring pressure plate 20 is detachably mounted on the base plate II 5 using multiple bolts. The adjusting rod 19 passes downward through the spring pressure plate 20 and the base plate II 5, and the bottom end of the adjusting rod 19 is connected to the Y-axis rack assembly 6. In this invention, the diameter of the hole on the base plate II 5 through which the adjusting rod 19 passes is larger than the diameter of the lower part of the adjusting rod 19. The spring 21 is sleeved on the lower part of the adjusting rod 19, with the bottom end of the spring 21 pressing against the Y-axis rack assembly 6 and the upper end of the spring 21 abutting against the spring pressure plate 20. Pulling the adjusting rod 19 upward will disengage the Y-axis rack assembly 6 and compress the spring 21. In this state, the base plate I 12 can move along the Y-axis direction on its plate assembly 1 to adjust and release the adjusting rod 19. The spring 21 extends and pushes the rod downward to engage the Y-axis rack assembly 6.

[0029] like Figure 1 and Figure 4As shown, the Y-axis rack assembly 6 of this utility model includes an upward Y-axis rack 22 and a downward Y-axis rack 23. The downward Y-axis rack 23 is fixed on the base plate assembly 1. The upward Y-axis rack 22 is fixedly connected to the adjusting rod 19 of the Y-axis adjusting mechanism 16. When the adjusting rod 19 pulls the upward Y-axis rack 22 upward and disengages from the downward Y-axis rack 23, the base plate II 5 can move along the Y-axis direction. When the adjusting rod 19 is released, the upward Y-axis rack 22 moves downward and engages with the downward Y-axis rack 23, preventing the base plate II 5 from moving along the Y-axis direction. The X-axis rack assembly II 9 includes an upward X-axis rack II and a downward X-axis rack II. The downward X-axis rack II is fixed on the base plate II 5. The upward X-axis rack II is fixedly connected to the adjusting rod 19 of the X-axis adjusting mechanism II 17. When the adjusting rod 19 pulls the upward X-axis rack II upward and disengages from the downward Y-axis rack 23, the base plate II 5 can move along the Y-axis direction. When the X-down rack II disengages, the moving block II8 can move along the X-axis. When the adjusting rod 19 is released, the X-up rack II moves downward and engages with the X-down rack II, preventing the moving block II8 from moving along the X-axis. The X-axis rack assembly I15 includes an X-up rack I and an X-down rack I. The X-down rack II is fixed on the base plate I12. The X-up rack I is fixedly connected to the adjusting rod 19 of the X-axis adjusting mechanism I18. When the adjusting rod 19 pulls the X-up rack I upward and disengages from the X-down rack I, the moving block I14 can move along the X-axis to adjust the distance between the X-axis pitch component 2 and the XY-axis pitch component 3. When the adjusting rod 19 is released, the X-up rack I moves downward and engages with the X-down rack I, preventing the moving block I14 from moving along the X-axis.

[0030] like Figure 1 As shown, this utility model has two or more Y-axis guide rails 24 arranged on the substrate assembly 1 along the Y-axis direction, as per the appendix of this utility model. Figure 1 Three Y-axis guide rails 24 are evenly spaced on the substrate assembly 1. Multiple Y-axis sliders 25 are located at the bottom of the base plate II 5. The Y-axis sliders 25 slide against the Y-axis guide rails 24, allowing the base plate II 5 to move along the Y-axis on the substrate assembly 1. A blocking block is fixed at each end of each Y-axis guide rail 24 to effectively prevent the Y-axis sliders 25 from slipping off the Y-axis guide rails 24. Figure 1 and Figure 2 As shown, an X-axis guide rail II26 is provided on the base plate II5 along the X-axis direction. A reference positioning block II7 is fixed on the X-axis guide rail II26, and a movable positioning block II10 is slidably disposed on the X-axis guide rail II26, facilitating the sliding adjustment of the movable positioning block II10 in the X-axis direction. Figure 1 and Figure 3As shown, an X-axis guide rail I27 is provided on the base plate I12 along the X-axis direction. The reference positioning block I4 is fixed on the X-axis guide rail I27, and the movable positioning block I13 is slidably disposed on the X-axis guide rail I27, facilitating the sliding adjustment of the movable positioning block I13 in the X-axis direction. In the optimal embodiment of this invention, Y-axis rack assemblies 6 are provided at both ends of the base plate II5 and between it and the base plate assembly 1. A Y-axis adjustment mechanism 16 is provided at each end of the base plate II5, respectively used to adjust the engagement and disengagement of the two Y-axis rack assemblies 6.

[0031] like Figure 1 As shown, Y-axis through-beam sensors 28 are arranged at intervals along the X-axis direction on the substrate assembly 1, with the same number as the reference positioning blocks I4. The position of the Y-axis through-beam sensors 28 in the X-axis direction is adjustable. The Y-axis through-beam sensors 28 are used to detect the presence of the battery cell. In this invention, the Y-axis through-beam sensors 28 are arranged on the edge of the substrate assembly 1 at one end where the X-axis pitch converter 2 is installed and at the edge of the end opposite to the X-axis pitch converter 2. The height of the Y-axis through-beam sensors 28 is less than the height of the top of the battery cell. When the light emitted by the Y-axis through-beam sensors 28 is blocked, it indicates that a battery cell is placed between the X-axis pitch converter 2 and the XY-axis pitch converter 3. Otherwise, no battery cell is placed between the X-axis pitch converter 2 and the XY-axis pitch converter 3. In this invention, a profile 31 is fixed at the edge of the substrate assembly 1. Each end of the profile 31 is detachably mounted on the substrate assembly 1 using a connecting block 32. A transition block 33 is provided on the profile 31 using bolts and nuts. A guide rod 34 is provided on the transition block 33. The guide rod 34 is vertically arranged. A sensing bracket 35 is provided on the upper part of the guide rod 34. A Y-direction through-beam sensor 28 is mounted on the sensing bracket 35. In this invention, a Y-direction through-beam sensor 28 is provided between each reference positioning block I4 and the moving positioning block I13, so that the number of Y-direction through-beam sensors 28 is equal to the number of battery cells placed in this invention.

[0032] like Figure 1As shown, this invention provides X-axis through-beam sensors I 29 on both sides of the substrate assembly 1 near the X-axis pitch-changing assembly 2. The mounting structure of the X-axis through-beam sensors I 29 is the same as that of the Y-axis through-beam sensors 28, except that the transition block of the X-axis through-beam sensors I 29 is directly mounted on the edge of the substrate assembly 1. X-axis through-beam sensors II 30 are provided at both ends of the base plate II 5. The X-axis through-beam sensors I 29 and II 30 respectively detect the over-height of the battery cell from both ends. The mounting structure of the X-axis through-beam sensors II 30 is the same as that of the X-axis through-beam sensors I 29, except that the transition block of the X-axis through-beam sensors II 30 is mounted on the base plate II 5. The height of the X-axis through-beam sensors I 29 and II 30 is greater than the height of the top of the battery cell. When the light emitted by the X-axis through-beam sensors I 29 and II 30 is blocked by the battery cell, it indicates that the battery cell is over-height.

[0033] When using this invention, the distance between the reference positioning block I4 and the moving positioning block I13, the distance between the reference positioning block II7 and the moving positioning block II10, and the distance between the X-axis pitch changing component 2 and the XY-axis pitch changing component 3 are adjusted according to the specifications of the battery cell. This invention enables rapid model changeover during battery cell model cutting and improves model changeover efficiency.

[0034] The adjustment method for the distance between the reference positioning block I4 and the movable positioning block I13 is as follows: Pull the adjusting rod 19 of the X-axis adjusting mechanism I18 upwards, causing the X-axis upward rack I (not shown in the figure) of the X-axis rack assembly I15 to move upwards and disengage from the X-axis downward rack I (not shown in the figure). Then, move the movable block I14 horizontally to adjust the movable positioning block I13 in the X-axis direction until the distance between the reference positioning block I4 and the movable positioning block I13 matches the battery cell. Release the adjusting rod 19 of the X-axis adjusting mechanism I18. Under the action of the spring 21, the X-axis upward rack I moves downwards and engages with the X-axis downward rack I. At this time, the movable positioning block I13 cannot move relative to the reference positioning block I4, and the distance adjustment is complete. The adjustment method for the distance between the reference positioning block II7 and the movable positioning block II10 is the same as that for the distance between the reference positioning block I4 and the movable positioning block I13, and will not be described in detail here.

[0035] The method for adjusting the distance between the X-axis pitch converter 2 and the XY-axis pitch converter 3 is as follows: Pull the adjusting rods 19 of the two Y-axis adjusting mechanisms 16 upward, so that the two Y-up racks 22 move upward and disengage from the two Y-down racks 23 respectively. Then move the base plate II5 along the Y-axis direction to adjust the distance between the X-axis pitch converter 2 and the XY-axis pitch converter 3. After the adjustment is completed, release the adjusting rods 19 of the two Y-axis adjusting mechanisms 16. Under the action of the spring 21, the two Y-up racks 22 move downward and engage with the two Y-down racks 23 respectively, thus completing the adjustment of the distance between the X-axis pitch converter 2 and the XY-axis pitch converter 3.

[0036] Unless otherwise specified in the above description, all parts are existing technology or can be implemented using existing technology. Furthermore, the specific embodiments described in this utility model are merely preferred embodiments of the invention and are not intended to limit the scope of this utility model. That is, all equivalent changes and modifications made within the scope of this utility model patent should be considered within the technical scope of this utility model.
