Description

Technical Field

[0001] The present invention belongs to the field of detection technology, specifically relates to size measurement, and more particularly to a detection device and method for a combined battery block. Background Art

[0002] In order to improve the overall structural strength and collision resistance of the rectangular battery block, a metal frame of matching size needs to be set on the outer wall of the combined battery block.

[0003] In the related art, two rectangular battery blocks are connected in series (the voltage is superimposed after series connection, and the discharge capacity is enhanced), tightly fitted and placed horizontally at the assembly station, and the assembly robot moves downward to put the metal frame on the outer walls of the two tightly fitted rectangular battery blocks.

[0004] However, during the horizontal positioning and vertical assembly processes of the assembly robot, shaking may cause the metal frame to shift relative to the rectangular battery blocks. When the shifted metal frame is placed between two adjacent rectangular battery blocks, the bottom wall of the metal frame rubs against the surface of the rectangular battery blocks, causing scratches. Furthermore, when the side walls of the two rectangular battery blocks are tightly attached and placed horizontally at the assembly station, since the two rectangular battery blocks are not suitable for gluing, the placement deviation may cause a gap between the two rectangular battery blocks when they are placed horizontally, further increasing the risk of the metal frame rubbing against the surface and edges of the rectangular battery blocks.

[0005] Therefore, how to prevent the surface of the rectangular battery block from being scratched during the metal frame assembly process is a technical problem that urgently needs to be solved in this field.

[0006] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of related technology.

[0009] In an optional embodiment, the length and width of the limiting plate are consistent with the length and width of two adjacent rectangular battery blocks.

[0010] In an optional embodiment, the outer ends of the two guide plates protrude from the limiting plates respectively, and the protruding portions are provided with inclined surfaces; The metal frame moves downward to abut against the inclined surface, and the guide plate contracts inward to guide the metal frame to move downward in the center.

[0011] In an optional embodiment, the limiting component includes: A limiting member is slidably disposed in the limiting plate, and has two extension rods symmetrically disposed on a side away from the guide plate; A driving member, one end of which is disposed on the inner wall of the guide plate and the other end of which extends toward the limiting member; a connecting member, which slides through the driving member and has two ends respectively abutting against the limiting members; When the two guide plates retract toward the center of the limiting plate, the driving connecting member moves along the width direction of the limiting plate; The two limiting members and the two guide plates move toward each other, and the extension rod is suitable for clamping the two rectangular battery blocks to eliminate the gap.

[0012] In an optional embodiment, two accommodating cavities are opened in the limiting plate, and the limiting member and the driving member are respectively slidably arranged in the accommodating cavities; A compression spring is provided at the end of the driving member, and one end of the compression spring abuts against the limiting member; When the guide plate contracts toward the center of the limit plate, the driving member pushes the compression spring to move the limit member toward the center of the limit plate; When the connecting member moves along the width direction of the limiting plate, the connecting member drives the limiting member to move toward the guide plate to compress the compression spring.

[0013] In an optional embodiment, the connecting member is in a "Z" shape, and a first guide surface is provided at each end, and the two first guide surfaces are parallel to each other.

[0014] In an optional embodiment, the limiting member is provided with two second guide surfaces adapted to the first guide surface near the connecting member, and the first guide surface abuts against the second guide surface; When the connecting member moves along the width direction of the limiting plate, the second guide surface pushes the first guide surface, so that the limiting member and the guide plate move toward each other.

[0015] In an optional embodiment, an oblique hole matching the connecting member is opened in the middle of the driving member; When the driving member contracts toward the center of the limiting plate, the inclined surface pushes the connecting member to move along the width direction of the limiting plate.

[0016] In an optional embodiment, a positioning groove is respectively provided at both ends of the limiting plate in the width direction, and the width of the positioning groove is not less than the width of the guide plate.

[0017] In an optional embodiment, the bottom wall of the extension rod is provided with a protrusion adapted to the groove on the surface of the rectangular battery block; When the limiting plate abuts against the surface of the rectangular battery block, the protrusion is suitable for inserting into the groove.

[0019] The present invention provides a combined battery block detection device and method. By combining a guide plate and a stopper assembly, the guide plate's slope guides the metal frame's initial horizontal positioning when the metal frame presses down on the guide plate (resolving robotic arm wobbling and offset). This not only aligns the metal frame but also prevents friction between the metal frame and the rectangular battery block surface. Simultaneously, a linkage structure drives the stopper to eliminate gaps between the battery blocks (resolving assembly gaps). The two work together to ensure frictionless vertical descent of the metal frame. The two stoppers clamp the two rectangular battery blocks, eliminating the gap between them and further reducing the likelihood of friction between the metal frame and the rectangular battery blocks as it moves downward.

[0030] Research has found that in related technologies, two rectangular battery blocks are connected in series (the voltage is superimposed after series connection, enhancing discharge capacity), tightly fitting and placed horizontally at an assembly station. The assembly robot then moves downward to fit the metal frame over the outer walls of the tightly fitting rectangular battery blocks. However, during the horizontal positioning and vertical assembly processes of the assembly robot, shaking may cause the metal frame to shift relative to the rectangular battery blocks. When the offset metal frame is placed between two adjacent rectangular battery blocks, friction between the bottom wall of the metal frame and the surface of the rectangular battery blocks causes scratches. Furthermore, when the side walls of the two rectangular battery blocks are tightly fitted and placed horizontally at the assembly station, glue is not suitable for gluing the two rectangular battery blocks together. This deviation in placement may result in gaps between the two rectangular battery blocks when they are placed horizontally, further increasing the risk of the metal frame rubbing against the surface of the rectangular battery blocks.

[0031] Therefore, how to prevent the surface of the rectangular battery block from being scratched during the metal frame assembly process is a technical problem that urgently needs to be solved in this field.

[0032] The defects in the above solutions and the causes of their occurrence are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0035] like Figures 1 to 5 As shown, at least one embodiment provides a combined battery block detection device, including: The adjustable limit structure 1, which is positioned and adjustable above the assembly station 3, comprises a horizontal limit plate 11 with a sliding slot 111 defined in its bottom wall. The length and width of the limit plate 11 correspond to the lengths and widths of two adjacent rectangular battery blocks 2. Two guide plates 12 are slidably mounted on either end of the limit plate 11. The outer ends of the guide plates 12 protrude beyond the limit plate 11, and the protruding portions are provided with inclined surfaces 110. When the metal frame 4 moves downward and abuts against the inclined surfaces 110, the guide plates 12 retract inward, guiding the metal frame 4 downward and centered.

[0036] Reference Attachment Figure 3The two limiting assemblies 13 are slidably disposed within the sliding slots 111 and are linked to the guide plates 12. The limiting assemblies 13 are linked to the guide plates 12 via a driving member 132. That is, when the guide plates 12 are pushed inward and retracted, the corresponding limiting members 131 simultaneously slide outward to clamp and limit the two rectangular battery blocks 2. Specifically, the two rectangular battery blocks 2 are placed horizontally in the assembly station 3, with their side walls abutting each other. The adjusting limiting structure 1 moves downward until it abuts the rectangular battery blocks 2. The metal frame 4 moves downward to pass over the adjusting limiting structure 1 and fits over the outer walls of the two rectangular battery blocks 2. The two rectangular battery blocks 2 are placed horizontally in the assembly station 3. When the metal frame 4 presses down on the guide plates 12, the guide plates 12 retract toward the center of the limiting plate 11, guiding the metal frame 4 to move downward in the center. The inward retraction of the two guide plates 12 drives the two limiting assemblies 13 to move toward each other, clamping the two rectangular battery blocks 2 to eliminate the gap.

[0037] In this embodiment, the inner ring size of the metal frame 4 is consistent with the outer ring size of the two tightly fitting rectangular metal blocks 2. Therefore, when a conventional manipulator clamps the metal frame 4 and moves it downward to directly fit over the two rectangular battery blocks 2, if the manipulator shakes during movement, the metal frame 4 will be offset relative to the rectangular battery blocks 2. This will not only prevent the metal frame 4 from being fitted over the two rectangular battery blocks 2, but also pose the risk of scratches caused by friction between the bottom wall of the metal frame and the surface of the rectangular battery blocks. However, when the manipulator stably moves the metal frame 4 over the rectangular battery blocks 2, if the two rectangular battery blocks 2 do not fit tightly together (i.e., an assembly gap occurs), the metal frame 4 will be unable to fit over the two rectangular battery blocks 2 when it moves downward. Therefore, it is necessary to adjust the limiting structure 1 to guide and correct the downward position of the metal frame 4, and to squeeze and assist the two rectangular battery blocks to fit tightly together. In this embodiment, the staggered protrusions 139 are inserted into the grooves 20 of different rectangular battery blocks 2, and as the guide plate 12 shrinks into the limit plate 11, the two relatively arranged protrusions 139 move away from each other to pull the two rectangular battery blocks 2 toward each other synchronously, thereby achieving a correction effect.

[0038] Preferably, a manipulator is provided on the assembly station 3 for lifting and lowering. The manipulator is adapted to grip the metal frame 4. After the limiting structure 1 is adjusted to abut against the rectangular battery block 2, the manipulator grips the metal frame 4 and moves it downward until it fits over the outer walls of the two rectangular battery blocks 2. Through the cooperation of the guide plate 12 and the limiting assembly 13, when the metal frame 4 presses down on the guide plate 12, the inclined surface 110 of the guide plate 12 can guide the lateral displacement of the metal frame 4, not only correcting the metal frame 4 but also preventing friction between the metal frame 4 and the surface of the rectangular battery block 2. At the same time, the two limiting members 131 clamp the two rectangular battery blocks 2, eliminating the gap between the two rectangular battery blocks 2 and further reducing the probability of friction between the metal frame 4 and the rectangular battery block 2 when it moves downward.

[0039] Reference AttachmentFigure 2 and Figure 3 , the limiting assembly 13 includes: a limiting member 131, which is slidably arranged in the limiting plate 11, and two extension rods 134 are symmetrically arranged on the side away from the guide plate 12; two accommodating chambers 112 are opened in the limiting plate 11, and the two accommodating chambers 112 are respectively arranged on both sides of the sliding groove 111, and are interconnected with the sliding groove 111. The limiting member 131 and the driving member 132 are respectively slidably arranged in the accommodating chamber 112. A limiting block 15 is provided in the accommodating chamber 112, and the connecting member 133 is slidably arranged in the limiting block 15. The driving member 132 passes through the limiting block 15, and the moving directions of the connecting member 133 and the driving member 132 are cross-staggered. Refer to the attached Figure 4 The inner frame of the limit block 15 is flat, and both surfaces of the connector 133 near the limit block 15 are flat and fit closely to the inner frame of the limit block 15. The driver 132 has one end mounted on the inner wall of the guide plate 12 and the other end extending toward the limit block 131. The connector 133 slides through the driver 132, with both ends abutting against the limit block 131. The driver 132 is provided with an oblique hole 14 that mates with the inclined surface of the connector 133. A compression spring 135 is mounted at the end of the driver 132, with one end abutting against the limit block 131. After the metal frame 4 detaches from the outside of the guide plate 12, the compression spring 135 pushes the guide plate 12 outward and simultaneously pushes the limit block 131 inward.

[0040] Reference Attachment Figure 5 When the metal frame 4 moves downward and initially contacts the inclined surface 110, the inclined surface 110 of the guide plate 12 can guide the metal frame 4 to be horizontally positioned for the first time; the metal frame 4 continues to move downward, pushing the guide plate 12 to retract and move into the limit plate 11, and the guide plate 12 drives the driving member 132 to retract toward the center of the limit plate 11. Figure 5 F1 in the figure represents the pressure exerted by the metal frame 4 on the guide plate 12, and also represents the movement direction of the driver 132. At this time, the driver 132 squeezes the compression spring 135, causing it to deform. Because the ends of the connecting member 133 respectively abut the two second guide surfaces 137 at the end of the limiter 131, although the driver 132 moves inward and squeezes the compression spring 135, the compression spring 135 cannot push the limiter 131 to move inward in a synchronous manner. Figure 5 F2 represents the moving direction of the extension rod, F3 represents the moving direction of the connecting rod; and F4 represents the moving direction of the limiting member 131.

[0041] Reference Attachment Figure 4 and Figure 5As the guide plate 12 continues to shrink and move into the limiting plate 11, the through-slant hole 14 provided on the driving member 132 pushes the connecting member 133 to move along the width direction of the limiting plate 11 (i.e., the inner wall of the through-slant hole 14 pushes the connecting member 133 to move along the width direction of the limiting plate 11). Figure 5 When the connecting member 133 moves relative to the driving member 132 (moves in the direction of F3), Figure 5 The first guide surface 136 below the connecting member 133 and the limiting member 131 are located at Figure 5 The second guide surface 137 at the lower middle part abuts against the first guide surface 136, and the first guide surface 136 pushes the second guide surface 137, thereby pushing the limiting member 131 along the Figure 5 At this time, the limit member 131 continues to squeeze the compression spring 135, and drives the extension rod 134 to move outward synchronously (such as Figure 5 F2 represents the moving direction of the extension rod); the two extension rods 134 arranged opposite to each other move outward synchronously to pull the two rectangular battery blocks 2 toward each other to eliminate the gap between the rectangular battery block 2 brackets.

[0042] Reference Attachment Figure 3 The connecting member 133 is in a "Z" shape, and is provided with a first guide surface 136 at both ends, and the two first guide surfaces 136 are parallel to each other. The limiting member 131 is provided with two second guide surfaces 137 adapted to the first guide surfaces 136 near the connecting member 133, and the first guide surfaces 136 abut against the second guide surfaces 137; When the connecting member 133 moves along the width direction of the limiting plate 11 , the second guiding surface 137 pushes the first guiding surface 136 , so that the limiting member 131 and the guide plate 12 move toward each other.

[0043] The driving member 132 has a through oblique hole 14 in the middle thereof, which matches the connecting member 133. When the driving member 132 retracts toward the center of the limiting plate 11, the guide plate 12 is simultaneously retracted into the limiting plate 11. The inclined surface 110 pushes the connecting member 133 to move along the width direction of the limiting plate 11 .

[0044] Reference Attachment Figure 2 A positioning groove is respectively provided at both ends of the width direction of the limiting plate 11 , and the width of the positioning groove is not less than the width of the guide plate 12 .

[0045] Reference Attachment Figure 3 The bottom wall of the extension rod 134 is provided with a protrusion 139 adapted to the groove 20 on the surface of the rectangular battery block 2; wherein, when the limiting plate 11 abuts against the surface of the rectangular battery block 2, the protrusion 139 is suitable for being inserted into the groove 20.

[0046] Here’s how it works: Two rectangular battery blocks 2 are placed horizontally in the assembly station 3, with their side walls abutting each other. The adjustable limiting structure 1 moves downward until it abuts the rectangular battery blocks 2. At this point, a protrusion 139 is inserted into the corresponding groove 20. The metal frame 4 moves downward to pass over the adjustable limiting structure 1 and fits over the outer wall of the assembly formed by the two rectangular battery blocks 2. Reference Attachment Figure 4 When the metal frame 4 moves downward until it abuts the inclined surface 110 of the guide plate 12, the guide plate 12 shrinks toward the center of the limiting plate 11, guiding the metal frame 4 to move downward in the center; specifically, the guide plate 12 pushes the driving member 132 to slide inward, and the driving member 132 pushes the connecting member 133 to move along the width direction of the limiting plate 11. The first guide surface 136 abuts against the second guide surface 137 to move the limiting member 131 toward the guide plate 12, and the limiting member 131 moves outward to drive the protrusion 139 to slide in the groove 20. The oppositely arranged protrusions 139 respectively squeeze the corresponding rectangular battery blocks 2, so that the end walls of the two rectangular battery blocks 2 are tightly fitted to eliminate the gap between the two rectangular battery blocks 2. Figure 4 F1 indicates the inward sliding direction of the guide plate 12 ; F2 indicates the outward sliding direction of the limiting member 131 .

[0047] At least one embodiment provides a detection method for a combined battery block detection device, the detection method comprising: Two rectangular battery blocks 2 are placed horizontally on the assembly station 3 with their side walls abutting against each other; Adjust the limiting structure 1 downward until it contacts the rectangular battery block 2; The metal frame 4 moves downward to pass over the adjustment limit structure 1 which is sleeved on the outer wall of the assembly consisting of the two rectangular battery blocks 2; When the metal frame 4 presses down the guide plate 12: The guide plate 12 shrinks toward the center of the limiting plate 11, guiding the metal frame 4 to move downward in the center; When the two guide plates 12 retract inwardly, the two limiting assemblies 13 are driven to move toward each other. The two limiting assemblies 13 clamp the two rectangular battery blocks 2 to eliminate the gap.
