Description

Technical Field

[0001] This invention relates to the field of lithium battery production technology, specifically to an integrated high-speed 3-channel cylindrical surface appearance inspection device. Background Technology

[0002] Currently, the country is vigorously promoting new energy, and the lithium battery industry has also developed significantly. Under these circumstances, the requirements for the appearance quality of lithium batteries are becoming increasingly stringent. Therefore, it is necessary to strengthen the effective control of the cell production process to improve cell quality, which involves the cell appearance inspection process (cylindrical surface inspection and cylindrical end face inspection).

[0003] Currently, the cylindrical surface inspection of lithium batteries cannot meet the requirements for high-speed inspection. Existing technology achieves a low cycle time of only 100 PPM using a 2+2+1 configuration: double-row feeding with a double-row cylindrical surface inspection mechanism and a single-line end-face inspection. A cycle time of 150 PPM is typically achieved using two devices. The efficiency of a single-row cylindrical surface inspection is 50 PPM, while the end-face inspection efficiency is approximately 150 PPM. The end-face efficiency has a significant margin, and current inspection methods use six cameras for the end-face inspection, resulting in high costs.

[0004] Therefore, there is an urgent need to design a testing device that can meet the high-speed testing requirement of 150PPM for the appearance inspection equipment of large cylindrical batteries. Summary of the Invention

This invention transforms two rows of equidistant and continuously input battery streams into three rows of equidistant and continuously transported battery streams and performs cylindrical surface rotation detection. After the cylindrical surface detection is completed, the battery streams are merged into one row for subsequent end face detection.

[0041] 2. In order to reduce costs, this invention adopts a 2+3+1 layout to make full use of the efficiency of each testing station.

[0042] 3. This invention has a simple structure, excellent performance, low hardware cost, and significantly reduced equipment footprint, energy consumption, and transportation costs.

All rotating wheels and cam assemblies rotate in the same direction, with the battery located at the top of the mechanism, which facilitates observation and adjustment.

[0124] In one embodiment, the transmission ratio of the synchronous pulleys at various locations is:

[0125] Feeding wheel: Feeding cam: 2-part 3-rotating cage: Rotary drive cam 2: Rotary drive cam 1: Rotary drive cam 2: 3-in-1 - Rotating cage: The transmission ratio of the unloading wheel is: 1:2:1:4:4:4:4 / 5:2.

[0126] The principle by which the battery flow is transformed from two rows of equidistant and continuous input to three rows of equidistant and continuous delivery in this invention is as follows:

[0127] like Figure 25 As shown, dual-row batteries are continuously fed in side-by-side. To convert two rows into three rows, multiples of 2 and 3 are needed. To minimize the size of the mechanical mechanism, this invention uses the smallest multiple of 2 and 3, 6. The dual-row batteries are divided into groups of six. The first six batteries are recorded as group 1. Group 1 has two rows: the first row has three batteries, occupying positions 1, 2, and 3; the second row also has three batteries, occupying positions 1, 2, and 3. To convert two rows into three, one battery is removed from the first row and one battery from the second row, forming a new row. To coordinate... Figure 26 The idea is to name the new row the second row and the original second row the third row, resulting in three rows of batteries. However, three rows alone are insufficient. To facilitate cylindrical surface detection, the spacing between batteries in each row must be identical. This ensures that each battery receives the same detection conditions when entering the detection channel—consistent detection time and rotation speed—ultimately achieving uniform detection accuracy and efficiency. Furthermore, after the cylindrical surface detection is complete, the three rows must be combined into one. Therefore, the three rows cannot be placed side-by-side; they must be staggered, with a specific order, to interweave and merge into a single row.

[0128] Therefore, to achieve its intended functions, this invention needs to accomplish five functions:

[0129] 1. Implement 6 battery bays connected in series.

[0130] 2. Distribute the batteries from the original 3 battery slots to these 6 battery slots.

[0131] 3. Convert the 2-row batteries into 3-row batteries and increase the spacing between the rows to match the spacing of the cylindrical inspection station.

[0132] 4. Ensure that the spacing between the batteries in all three rows is consistent.

[0133] 5. Ensure that the batteries in the three rows are staggered relative to the other two rows, and that adjacent batteries can be interleaved and merged into one column.

[0134] like Figure 25As shown: by doubling the distance between the first and second rows of batteries, the 3 positions become 6.

[0135] Implementation process: 2+3+1, such as Figure 26 , 27 The diagram shows the battery flow of the entire system.

[0136] 2 rows become 3 rows, such as Figures 29a to 29d As shown: The first and second rows of channels have coaxial feeding wheels and feeding cams. The feeding wheel has six evenly distributed grooves, with identical groove positions in both rows. The two corresponding feeding cams, projected along the C-axis, combine to form a cam with six grooves. When the feeding wheels of both channels rotate half a turn to input 3+3 batteries, the feeding cam of the two channels rotates one full turn, outputting a uniform six-groove groove, as shown in the C-axis diagram. However, these six positions are distributed across different locations on the feeding cams of the two channels. The first row corresponds to... Figures 29a to 29d AA Figure 5 , 4 1. The battery delay (phase change) of positions 6 and 2 corresponds to the second row. Figures 29a to 29d In Figure 6.3.2, the battery delay at position 4 is the phase-change output. The battery delay principle is as follows: the battery is held in place by a feed phase-change cam surface and a pair of forks, and the battery waits for the cam groove to turn before being taken away. This achieves delayed battery delivery. In a 6-to-3 slot system, the delay can be achieved for one slot.

[0137] like Figure 8 As shown: In the 2-to-3 cam mechanism, the 2-to-3 inner cam assembly is connected to the main drive mounting plate and the auxiliary mounting plate via two anti-rotation arms and connecting columns, thus preventing rotation. The inner sides of the two ends of the 2-to-3 rotating cage are sleeved on the outer side of the 2-to-3 inner cam assembly via bearings, and its outer sides are also mounted on the main drive mounting plate and the auxiliary mounting plate via two end bearings. The outer two ends are also extended with tensioning sleeve synchronous pulleys. This allows the synchronous pulleys at both ends to drive the rotation simultaneously, ensuring that the 2-to-3 rotating cage receives a uniform torque force and preventing twisting deformation. The rotation of the 2-to-3 rotating cage drives the split-type fixture cup to move along the guide rod under the control of the cam groove, thus distributing the batteries to different channels.

[0138] like Figures 11a-11h As shown: There are 4 versions of the split-type jig cup assembly, A, B, C, and D, which are used to mate with the 4 cam grooves of the 2-part 3-cam.

[0139] Among them, version A corresponds to the 2-minute 3-cylinder cam groove 1, version B corresponds to the 2-minute 3-cylinder cam groove 2, version C corresponds to the 2-minute 3-cylinder cam groove 3, and version D corresponds to the 2-minute 3-cylinder cam groove 4.

[0140] To ensure the pressure angle of the cam trajectory of the 2-to-3 cylindrical cam is within a reasonable range, the 2-to-3 cam mechanism here has 12 separate fixture cups per revolution, twice the number of 6, corresponding to two operating cycles of the feeding phase change cam assembly. Each set of separate fixture cup assemblies 6, 5, 4, 3, 2, and 1 corresponds to: row 3, number 6 (corresponding to version A, 2-to-3 cylindrical cam groove 1); row 2, number 5 (corresponding to version C, 2-to-3 cylindrical cam groove 3); row 1, number 4 (corresponding to version D, 2-to-3 cylindrical cam groove 4); row 3, number 3 (corresponding to version A, 2-to-3 cylindrical cam groove 1); row 2, number 2 (corresponding to version B, 2-to-3 cylindrical cam groove 2); and row 1, number 1 (corresponding to version D, 2-to-3 cylindrical cam groove 4).

[0141] This achieves the transformation of the battery flow from 2 rows to 3 rows.

[0142] Three rows of cylindrical surface inspection, such as Figure 25-27 The diagram illustrates the operation of a battery within the cylindrical surface detection cam assembly. At the entry position, the battery is held in place by a fork and cam surface, exhibiting slight rotation. Once the groove of the subsequent cylindrical surface detection cam rotates, it will move the battery to the scanning station. At the scanning station, the battery is held by two cam surfaces. Because the cams rotate at a constant speed, they cause the battery to rotate in the opposite direction at a constant speed, allowing the scanner to scan the entire cylindrical surface. Once the groove of the subsequent cylindrical surface detection cam rotates, it will move the battery to the cylindrical surface imaging station. At the cylindrical surface imaging station, the battery is also held by two cam surfaces. Because the cams rotate at a constant speed, they cause the battery to rotate in the opposite direction at a constant speed, allowing the line scanner to photograph the entire cylindrical surface.

[0143] The cylindrical inspection cam has only one groove. Each time a battery arrives, the cylindrical inspection cam rotates once, and then the battery is transported to the next workstation after inspection.

[0144] The three rows of cylindrical surface inspection stations are 120 degrees out of phase, proceeding sequentially from the first row to the third row, and are coordinated with the output of the 2-to-3 cam mechanism.

[0145] Among them, the rotary drive camshaft 2, which is close to the 2-to-3 cam mechanism, is also used as the transmission shaft for the power of the 2-to-3 rotating cage 2.

[0146] Among them, the rotary drive camshaft 1, which is close to the 3-in-1 cam mechanism, is also used as the transmission shaft for the power of the 3-in-1-rotor 2 end.

[0147] 3-in-1 battery current, such as Figure 20As shown, in the 3-in-1 cam mechanism, the 3-in-1 inner cam assembly is connected to the main drive mounting plate and the auxiliary mounting plate via two anti-rotation arms and connecting columns, thus preventing rotation. The inner sides of the two ends of the 3-in-1 rotating cage are sleeved on the outer side of the 3-in-1 inner cam assembly via bearings, and its outer sides are also mounted on the main drive mounting plate and the auxiliary mounting plate via two end bearings. The outer two ends are also extended with tensioning sleeve synchronous pulleys. This allows the synchronous pulleys at both ends to drive the rotation simultaneously, ensuring that the 3-in-1 rotating cage receives a uniform torque force and preventing twisting deformation. The rotation of the 3-in-1 rotating cage drives the split-type fixture cup to move along the guide rod under the control of the cam groove, thus distributing the batteries to different channels.

[0148] In a 3-in-1 cam mechanism, the number of fixture cups must be a multiple of 3 to achieve cyclic operation. Since the stroke of the fixture cups here is much larger than that of the 2-in-3 cam mechanism, in order to ensure that the cam pressure angle of the inner cam of the 3-in-1 is at a suitable level and to avoid excessive size, this mechanism preferably uses 15 sets of fixture cups.

[0149] The 3-in-1 rotary drum has three types of split-type jig cup components: version B, version C, and the middle-section split-type jig cup component. All are mounted on the guide rod of the 3-in-1 rotary drum and can rotate with it. Versions B and C can move along the guide rod, while the middle-section split-type jig cup component is fixed in the middle of the guide rod and cannot move relative to it. The movement of version B is controlled by groove 1 of the 3-in-1 inner cam, and the movement of version C is controlled by groove 2 of the 3-in-1 inner cam. Ultimately, all three jig cup components are merged into one row, thus achieving the function of merging three rows of battery current into one row.

[0150] The drive unit uses a synchronous belt pulley assembly, and each pulley is equipped with a tensioning sleeve for easy position adjustment. For example... Figure 25-27 As shown, all the rotating wheels and cam assemblies rotate in the same direction, and the battery flows above the mechanism.
