Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, specifically to a plate and frame positioning and correction device. Background Technology

[0002] A flow battery stack mainly consists of an outer end plate, an insulating plate, an end frame, a current collector, and multiple individual cells stacked together. Each individual cell is composed of a plate and frame assembly, a separator, bipolar plates, and electrodes. To improve assembly efficiency, the plate and frame assembly needs to be pre-assembled. Currently, fully automated pre-assembly lines are commonly used for this purpose. These lines employ a double-layer, high-speed chain, where a robotic arm picks up the plate and frame from the material box and places it onto a plate and frame fixture plate (e.g., ...). Figure 1 As shown in the figure, the plate frame is positioned, and then, under the action of the double-speed chain, it enters different sections with the fixture plate to perform related operations.

[0003] Placing the frame onto the fixture plate presents the following problems:

[0004] 1. Due to temperature changes and differences in production batches, it is difficult to achieve good consistency in the dimensions of the plate frame, which requires frequent adjustment of the positioning blocks on the jig plate, which is time-consuming and reduces production efficiency;

[0005] 2. Existing positioning mechanisms have two directions ( Figure 1 The positioning blocks on the left and bottom sides are adjustable, as are the other two directions ( Figure 1 The positioning blocks on the right and top sides are not adjustable, which causes the position of the center point of the plate frame placement area to change after each adjustment of the positioning blocks, affecting the assembly accuracy of subsequent processes and ultimately affecting the quality of the plate frame assembly. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a plate and frame positioning and correction device, which at least partially solves one of the technical problems existing in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A plate and frame positioning and correction device includes a jig plate with a polygonal plate and frame placement area at its upper end. At least one correction component is provided on the outer side of each side of the plate and frame placement area.

The bottom of the mounting frame is fixedly connected to the jig plate, and the mounting frame has a shaft hole. The shaft is inserted into the shaft hole and can slide within it. The positioning block is fixedly connected to one end of the shaft, and is adjacent to the plate and frame placement area relative to the mounting frame. The end of the positioning block away from the mounting frame has a chamfer located at its upper end. The stop is connected to the other end of the shaft, and is located on both sides of the mounting frame. The projection of the stop on the mounting frame is at least partially outside the outline of the shaft hole. One end of the elastic element is connected to the positioning block, and the other end is connected to the mounting frame. The elastic element presses the positioning block to move away from the mounting frame.

[0009] In some embodiments, the plate frame placement area is rectangular.

[0010] In some embodiments, a first correction component, a second correction component, a third correction component, and a fourth correction component are sequentially provided on the outer sides of the four sides of the plate frame placement area. The shaft on the first correction component is coaxial with the shaft on the third correction component, and the shaft on the second correction component is coaxial with the shaft on the fourth correction component.

[0012] In some embodiments, the mounting bracket includes a bracket and a bushing. The lower end of the bracket is fixedly connected to a fixture plate. The bracket has a through hole located above the fixture plate. The extension direction of the bushing is parallel to the horizontal plane. The bushing is fixedly connected to the bracket and is at least partially inserted into the through hole. The bushing is located on the bushing and inside the through hole.

[0013] In some embodiments, the bushing includes a cylindrical portion and a flat portion connected to each other, the cylindrical portion being inserted into a through hole, the flat portion being connected to a mounting bracket by fasteners, and the bushing hole passing through both the cylindrical portion and the flat portion.

[0014] In some embodiments, the shaft hole is a circular hole, the stop is an annular ring with an outer diameter larger than the diameter of the shaft hole, and the stop is sleeved on the shaft.

[0015] In some embodiments, the lower end of the positioning block is provided with a wheel groove, and a wheel axle parallel to the fixture plate and a roller rotatably connected to the wheel axle are provided in the wheel groove.

[0016] In some embodiments, the end face of the positioning block away from the mounting bracket is provided with multiple sliding ridges extending in the vertical direction.

[0017] In some embodiments, the elastic element is a compression spring sleeved on the shaft.

[0018] Compared with the prior art, this utility model realizes automatic positioning of the plate frame. When the size of the plate frame is inconsistent, there is no need to manually adjust the positioning block, saving the time spent on manual adjustment of the positioning block and improving assembly efficiency. Moreover, the correction component in this utility model can also automatically correct the plate frame, thereby ensuring the consistency of the assembled plate frame components and improving product quality.

[0036] See Figures 1-7 As shown, this utility model provides a plate and frame positioning and correction device, which includes a jig plate 1. The upper end of the jig plate 1 is provided with a polygonal plate and frame placement area. Each side of the plate and frame placement area is provided with at least one correction component 2. The correction component 2 is mainly composed of a mounting frame 3, a shaft 4, a positioning block 5, a stop 6 and an elastic component 7. The mounting bracket 3 is fixedly connected to the jig plate 1 by fasteners at its bottom. The mounting bracket 3 is provided with a shaft hole 323. The shaft 4 is inserted into the shaft hole 323 and can slide within the shaft hole 323. The positioning block 5 is fixedly connected to one end of the shaft 4. The positioning block 5 is located near the plate frame placement area of ​​the mounting bracket 3. The end of the positioning block 5 away from the mounting bracket 3 is provided with a chamfer 53. The chamfer 53 is located at the upper end of the positioning block 5. The chamfer 53 can be a right angle or a rounded corner. The stop 6 is connected to the other end of the shaft 4. The stop 6 and the positioning block 5 are located on the two sides of the mounting bracket 3, respectively. The projection of the stop 6 on the mounting bracket 3 is at least partially located outside the outline of the shaft hole 323. One end of the elastic member 7 is connected to the positioning block 5, and the other end of the elastic member 7 is connected to the mounting bracket 3. The elastic member 7 presses the positioning block 5 to move away from the mounting bracket 3.

[0037] In this invention, the elastic element 7 can be a compression spring and sleeved on the shaft 4. The elastic element 7 provides elastic force to keep the positioning block 5 in its normal position, at which time the stop 6 abuts against the mounting bracket 3 to prevent the shaft 4 from coming out of the shaft hole 323.

[0038] In some embodiments, the plate frame placement area is rectangular. Figure 3 The rectangular dashed-dot line outline in the diagram represents the area where the board frame is placed. See also... Figure 3 As shown, the four sides of the plate frame placement area are provided with a first correction component 21, a second correction component 22, a third correction component 23, and a fourth correction component 24 in sequence. The shaft 4 on the first correction component 21 is coaxial with the shaft 4 on the third correction component 23, and the shaft 4 on the second correction component 22 is coaxial with the shaft 4 on the fourth correction component 24.

[0039] In some embodiments, the number of the first correction component 21, the second correction component 22, the third correction component 23, and the fourth correction component 24 are all two. For example... Figure 3 As shown, two first correction components 21 are spaced apart, two third correction components 23 are spaced apart, and the distance between the two first correction components 21 is equal to the distance between the two third correction components 23; two second correction components 22 are spaced apart, two fourth correction components 24 are spaced apart, and the distance between the two second correction components 22 is equal to the distance between the two fourth correction components 24; moreover, the positioning blocks 5 on the two first correction components 21 are located on the same straight line, the positioning blocks 5 on the two second correction components 22 are located on the same straight line, the positioning blocks 5 on the two third correction components 23 are located on the same straight line, and the positioning blocks 5 on the two fourth correction components 24 are located on the same straight line.

[0040] In some embodiments, the mounting bracket 3 includes a support 31 and a bushing 32. See also Figure 5 As shown, the bracket 31 is made of metal plate bent into an L shape, or the bracket 31 can be made directly from angle steel. The lower end of the bracket 31 is fixedly connected to the fixture plate 1 by fasteners. The bracket 31 has a through hole 311 located above the fixture plate 1. The extension direction of the shaft hole 323 is parallel to the horizontal plane. The bushing 32 is fixedly connected to the bracket 31 and is at least partially inserted into the through hole 311. The shaft hole 323 is located on the bushing 32 and inside the through hole 311.

[0041] In some embodiments, the bushing 32 includes a cylindrical portion 321 and a flat portion 322 connected to each other. The cylindrical portion 321 is inserted into a through hole 311, and the flat portion 322 is connected to the mounting bracket 3 by fasteners. The shaft hole 323 passes through both the cylindrical portion 321 and the flat portion 322. Since the shaft 4 needs to move frequently within the shaft hole 323, there is a certain amount of wear between the shaft 4 and the mounting bracket 3. By disassembling the mounting bracket 3 into a bracket 31 and a bushing 32, wear can be limited to the shaft 4 and the bushing 32, avoiding the need to replace the entire mounting bracket 3 during maintenance and reducing maintenance costs. Furthermore, the cylindrical portion 321 allows the shaft hole 323 to have sufficient length, which helps to better restrict the direction of movement of the shaft 4.

[0042] In some embodiments, the shaft hole 323 is a circular hole, the shaft 4 is a round rod with a diameter slightly smaller than that of the shaft hole 323, and the stop 6 is annular with an outer diameter larger than that of the shaft hole 323. The stop 6 is sleeved on the shaft 4. In a specific implementation, an external thread can be provided at the end of the shaft 4 away from the positioning block 5, and an internal thread can be provided on the stop 6, so that the stop 6 is threadedly connected to the shaft 4.

[0043] See Figure 7As shown, in some embodiments, the lower end of the positioning block 5 is provided with a wheel groove 51. The wheel groove 51 contains a wheel axle 8 parallel to the fixture plate 1 and a roller 9 rotatably connected to the wheel axle 8. Both ends of the wheel axle 8 are connected to the positioning block 5, and the lower end of the roller 9 contacts the fixture plate 1. By adding the roller 9 below the positioning block 5, stable support is provided for the positioning block 5, ensuring that the positioning block 5 can move more smoothly outwards or inwards during use. Furthermore, the roller 9 can also prevent the positioning block 10 from rotating around the axis of the shaft 4.

[0044] In some embodiments, the end face of the positioning block 5 away from the mounting bracket 3 is provided with multiple sliding ribs 52 extending in the vertical direction. The sliding ribs 52 can reduce the friction between the positioning block 5 and the plate frame 10, so that the plate frame 10 can smoothly enter the plate frame placement area.

[0045] When the plate frame placement area in this utility model is rectangular, the principle of the plate frame positioning and correction device is as follows:

[0046] Let the length of the frame 10 be a, the width be b, and the allowable tolerance range for both the length and width of the frame 10 be ±2mm. The center point of the frame 10 is O. 板 When positioning block 5 is in its normal position, let the distance between two positioning blocks 5 that are opposite each other in the length direction be c. 腔 The distance between two positioning blocks 5 that are opposite each other in the width direction is d. 腔 Let a-4 < c 腔 <a-2, b-4 <d 腔 <b-2, The center point of the plate frame placement area enclosed by the correction components is set to O. 腔 Let F be the downward pushing force exerted by the robot arm on the plate frame 10. 推 The total frictional force generated by all the correction components in contact with the frame 10 is f. 摩 F 推 >f 摩 Because the distance c between the corresponding positioning blocks 5 is set 腔 d 腔 If the size is smaller than the minimum dimension of the plate frame 10, when the robot arm picks up the plate frame 10 from the material box and places it on the fixture plate 1, the plate frame 10 cannot fall directly into the plate frame placement area surrounded by the correction assembly. The plate frame 10 first contacts the chamfer on the positioning block 5, and the robot arm applies a downward pushing force F to the plate frame 10. 推 This causes the plate frame 10 to push the positioning block 5 in the correction assembly to move outward, and the elastic element 7 is compressed. When the distance between the corresponding positioning blocks 5 is consistent with the size of the plate frame 10, the positioning block 5 stops moving outward, and the plate frame 10 enters the plate frame placement area and is stuck between the positioning blocks 5, thus realizing the positioning of the plate frame 10.

[0047] Because the plate frame 10 is made of plastic, its dimensions are difficult to maintain consistently due to factors such as temperature and processing. Combined with placement deviations such as material stacking, it becomes difficult to ensure that the center O of the plate frame 10 aligns perfectly with the center O of the plate frame placement area when the robotic arm picks it up and places it into the plate frame placement area. 腔 Complete overlap can lead to some deviation in material placement. In such cases, this invention can correct the deviation. If the robot arm is pressing down on the plate frame 10, the center O of the plate frame 10... 板 Center O of the plate frame placement area 腔 If there is no overlap, the elastic force applied by the elastic element 7 in the correction assembly to the positioning block 5 will be different. After the robot arm disengages from the frame 10, the elastic force of the elastic element 7 will push the frame 10 to move, causing the center O of the frame 10 to... 板 Center O of the plate frame placement area 腔 By aligning the plates, the misalignment of the frame 10 is corrected.

[0048] This invention enables automatic positioning of the plate frame 10. When the dimensions of the plate frame 10 are inconsistent, there is no need to manually adjust the positioning block 5, saving the time spent on manual adjustment and improving assembly efficiency. Moreover, the correction component in this invention can automatically correct the deviation of the plate frame 10, thereby ensuring the consistency of the assembled plate frame components and improving product quality.
