Description

Technical Field

[0001] The utility model relates to the technical field of appearance surface detection, in particular to a polyhedron appearance surface detection device. Background Art

[0002] In recent years, the power battery industry has developed by leaps and bounds, especially with the explosion of the new energy vehicle industry, the demand and output of lithium batteries have increased year by year. Blue film coating is an important process in the production process of power batteries. As an insulating material, the blue film separates multiple battery cells, preventing the failure of a single battery cell from affecting other battery cells. The thickness of the blue film is small, only between 0.015mm-0.20mm. During the production process, it is easy to have scratches, breakages, wrinkles, bubbles and other defects. Some of these defects will affect the appearance of the product, and some will even damage the product function. Therefore, it is necessary to inspect the appearance of the battery cell after the blue film is wrapped.

[0003] At present, battery manufacturers mainly rely on manual visual inspection to inspect the appearance of battery cells after blue film wrapping. Manual inspection is required after the blue film wrapping process of each battery cell production line. This inspection method is inefficient and prone to missed inspections. The manual workload is large and cannot adapt to the rapidly growing production needs.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0064] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0065] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0067] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0068] In order to achieve efficient detection of the appearance surface of a polyhedron (such as battery cell A), the present application involves using a scanning camera to scan and photograph the appearance surface of the polyhedron, and automatically rotate / flip the polyhedron to be tested by using a rotating mechanism 1112 and a flipping mechanism 130, which can realize automatic switching of the scanning camera to multiple different appearance surfaces, improve operating efficiency, and save operating time.

[0069] See also Figures 1 to 10 , which describes the structure of a polyhedron appearance surface detection device.

[0070] In this application, the polyhedron is described by taking battery cell A as an example.

[0071] See also Figures 1 to 3 The inspection device includes an inspection platform 180 , an inspection station, a flipping mechanism 130 and a scanning camera unit 170 .

[0072] The inspection platform 180 serves as a supporting platform, providing support for the inspection station, the flip mechanism 130 and the scanning camera unit 170 , that is, the inspection station, the flip mechanism 130 and the scanning camera unit 170 are all located on the supporting platform.

[0073] In some embodiments of the present application, see Figure 1 The detection device also includes a frame 200, and the detection platform 180 is placed in the frame 200.

[0074] The frame 200 is constructed of aluminum alloy profiles, and a display, keyboard, mouse, human-computer interaction touch screen, control buttons, etc. are set on the front control panel of the frame 200. The operator can start and view the test results through the control panel.

[0075] In the present application, the inspection station is used to carry the battery cell A to be inspected.

[0076] In some embodiments of the present application, the number of the detection station may be at least one.

[0077] In some embodiments of the present application, when the number of the detection station is one, see Figures 2 to 4 When there is an inspection station 111, the inspection station 111 includes a rotating mechanism 1112, which is used to rotate the circumferential appearance surface of the battery cell A on a first plane (for example, the XY plane), so as to realize scanning of multiple different circumferential appearance surfaces by using the scanning camera unit 170 by rotating and switching the appearance surface of the battery cell A perpendicular to the XY plane.

[0078] In some embodiments of the present application, the battery cell A is a rectangular parallelepiped structure, and the surfaces perpendicular to the XY plane are four circumferential appearance surfaces (ie, Figure 4 The circumferential appearance surface A1, the appearance surface opposite to A1, A2, and the appearance surface opposite to A2 are shown in the figure).

[0079] The flipping mechanism 130 is used to flip the battery cell A on a second plane (eg, XZ plane, YZ plane) perpendicular to the first plane, so as to scan the remaining appearance surface by using the scanning camera unit 170 .

[0080] For example, the flipping mechanism 130 can flip the battery cell on the XY plane by 90° and then put it back on the inspection station 111, thereby switching the remaining appearance surfaces of the battery cell A (ie, appearance surface A3 of the battery cell A and the appearance surface opposite to A3).

[0081] The scanning camera unit 170 is disposed at the side of the inspection station 111 , and can scan the appearance surface of the battery cell A when the appearance surface faces the scanning camera 1713 in the scanning camera unit 170 .

[0082] In some embodiments of the present application, the number of the detection stations may be multiple, for example, two, denoted as detection station 111 and detection station 112, see Figure 4 .

[0083] The structures of the inspection station 111 and the inspection station 112 are the same.

[0084] At the same time, a battery cell A is placed on each of the inspection stations 111 and 112 .

[0085] The inspection station 111 / 112 is also used to rotate the circumferential appearance surface of the battery cell A on a first plane (eg, XY plane) so as to scan a plurality of different circumferential appearance surfaces using the scanning camera unit 170 by rotating and switching the appearance surface of the battery cell A perpendicular to the XY plane.

[0086] The flipping mechanism 130 is used to flip the cells A on the inspection stations 111 and 112 simultaneously on a second plane (eg, XZ plane, YZ plane) perpendicular to the first plane, and to scan the remaining appearance surface using the scanning camera unit 170 .

[0087] For example, the flipping mechanism 130 can flip the battery cell A on the XY plane by 90° and then put it back on the inspection stations 111 and 112, thereby switching the remaining appearance surfaces of the battery cell A (ie, the appearance surface A3 of the battery cell A and the appearance surface opposite to A3).

[0088] The scanning camera unit 170 may be disposed on the same side of the inspection stations 111 and 112 , so that when the appearance surface of the battery cell A faces the scanning camera 1713 in the scanning camera unit 170 , the appearance surface can be scanned.

[0089] Alternatively, in order to improve the scanning efficiency of the battery cell A, the scanning camera unit 170 may include a first scanning camera unit 171 arranged on the same side of the inspection station 111 and the inspection station 112 and a second scanning camera unit 172 arranged on the opposite side of the inspection station 111 and the inspection station 112.

[0090] The first scanning camera unit 171 is used to scan the appearance surfaces of the battery cells A on the same side of the detection stations 111 and 112 , and the second scanning camera unit 172 is used to scan the appearance surfaces of the battery cells A on the opposite sides of the detection stations 111 and 112 .

[0091] In this way, while the first scanning camera unit 171 scans the appearance surface on the same side of the battery cell A at the inspection stations 111 and 112 (for example, the appearance surface A1), the second scanning camera unit 172 can inspect the appearance surface on the opposite side of the battery cell at the inspection stations 111 and 112 (for example, the appearance surface directly opposite to the appearance surface A1).

[0092] The first scanning camera unit 171 and the second scanning camera unit 172 are used simultaneously to perform scanning and photographing, thereby improving scanning efficiency.

[0093] As described above, each scanning camera unit is configured to be movable, so that the appearance surface of the battery cell A can be completely scanned by moving the scanning camera in the scanning camera unit.

[0094] For example, the first scanning camera unit 171 is taken as an example for description.

[0095] See also Figure 8 The first scanning camera unit 171 includes a mounting bracket 1711, a sliding module 1712 and a scanning camera 1713, wherein the sliding module 1712 is mounted on the mounting bracket 1711, and the scanning camera 1713 is disposed thereon.

[0096] The sliding module 1712 adopts an electric cylinder module.

[0097] When the battery cell A arrives at the inspection stations 111 and 112 to be inspected, the electric cylinder module operates to drive the scanning camera 1713 to slide. The sliding direction of the scanning camera 1713 is consistent with the arrangement direction of the inspection stations 111 and 112. The camera scans to obtain a scanning image of a certain appearance surface.

[0098] It should be noted that the use of scanning camera 1713 to collect scanned images, and the processing and measurement of images to evaluate the quality of the appearance surface belong to the prior art, and this part is not the focus of the present invention, so it will not be repeated here.

[0099] The present application automatically switches between multiple different appearance surfaces of the battery cell A through the rotating mechanism 1112 and the flipping mechanism 130, avoiding the problem of low operating efficiency caused by manual flipping, and combines with the scanning camera unit 170 to improve the detection efficiency and detection accuracy.

[0100] In some embodiments of the present application, in order to improve the detection cycle, the number of detection stations can be multiple, recorded as a first group of detection stations 110 and a second group of detection stations 120, see Figures 2 to 5 .

[0101] The number of inspection stations in each of the first group of inspection stations 110 and the second group of inspection stations 120 is equal, and each group includes at least one inspection station, for example, two inspection stations.

[0102] See also Figure 4 , the first group of inspection stations 110 includes inspection stations 111 and 112; see Figure 5 The second group of inspection stations 120 includes inspection stations 121 and 122 .

[0103] Correspondingly, the flipping mechanism 130 should also be able to flip two battery cells A at the same time.

[0104] After the battery cell A on the first inspection station 110 rotates and completes the circumferential appearance scanning, it is flipped by the flipping mechanism 130 and then placed on the second inspection station 120 .

[0105] Correspondingly, the scanning camera unit 170 may include a first scanning camera unit 171 , a second scanning camera unit 172 , and a third scanning camera unit 173 .

[0106] See also Figure 2 , Figure 4 and Figure 8 The first scanning camera unit 171 is disposed on one side of the first group of inspection stations 110 , the second scanning camera unit 172 is disposed on the opposite side of the first group of inspection stations 110 , and the third scanning camera unit 173 is disposed on one side of the second group of inspection stations 120 .

[0107] And the first scanning camera unit 171, the second scanning camera unit 172 and the third scanning camera unit 173 are respectively configured to be movable as described above.

[0108] The first scanning camera unit 171 , the second scanning camera unit 172 , and the third scanning camera unit 173 have the same structure.

[0109] Since each battery cell A has many circumferential appearance surfaces, the first scanning camera unit 171 and the second scanning camera unit 172 are used for scanning to improve the scanning efficiency.

[0110] Thus, the first scanning camera unit 171 and the second scanning camera unit 172 are used to scan the circumferential appearance surface of the battery cell on the first group of inspection stations 110 , and the third scanning camera unit 173 scans the remaining appearance surface of the battery cell A on the second group of inspection stations 1202 .

[0111] In order to realize the rotation of the battery cell A on the detection station, in some embodiments of the present application, the detection station includes a rotation mechanism.

[0112] The following description takes the structure of the detection station 111 as an example.

[0113] See also Figure 4The inspection station 111 includes a base 1111, a rotating mechanism 1112, a support frame 1113, a lifting drive unit, a first clamping drive unit and a first clamping unit.

[0114] The base 1111 is a fixed platform of the inspection station 111, and is used to support the rotating mechanism 1112, the support frame 1113, the lifting drive unit, the first clamping drive unit and the first clamping unit.

[0115] The lifting driving part, the first clamping driving part and the first clamping part are all placed on the support frame 1113 , and the battery cell A is placed on the top of the support frame 1113 .

[0116] In the present application, the rotating mechanism is a rotating cylinder 1112, which is placed on a base 1111 and is used to output a rotating force.

[0117] The support frame 1113 is arranged on the rotating cylinder 1112, and the battery cell A is placed on the top. Therefore, when the rotating cylinder 1112 is working, the rotational force drives the support frame 1113 to rotate, so that the battery cell A can be rotated.

[0118] Among them, a placement plate 1117 is arranged on the top of the support frame 1113. The material of the placement plate 1117 is a non-metallic material, which is used for insulation and preventing the battery cell A from being bumped and scratched.

[0119] When the battery cell A to be tested rotates, in order to prevent the battery cell A from being overturned due to the rotation, a first clamping drive unit and a first clamping unit are provided, and the first clamping unit is driven by the first clamping drive unit to clamp / release the battery cell A.

[0120] The first clamping driving part is a clamping claw cylinder 1115 , and the first clamping part is a pair of clamping claws 1116 , which are respectively located on both sides of the placement plate 1117 .

[0121] In order to completely scan the entire appearance of cell A, see Figure 4 , this application sets up a lifting drive unit.

[0122] The lifting drive part is a lifting cylinder 1114 , which is used to lift the clamping jaw cylinder 1115 and a pair of clamping jaws 1116 .

[0123] After a pair of jaws 1116 grasp the battery cell A and the rotating mechanism 1112 operates to rotate the battery cell A into place, in order to avoid the obstruction of the jaws on the scanning of the appearance surface, after the pair of jaws 1116 release the battery cell A, the lifting cylinder 1114 operates to lower the jaw cylinder 1115 and the pair of jaws 1116, so that the pair of jaws 1116 avoid obstruction of the appearance surface of the battery cell A and scan its entire appearance surface, thereby ensuring detection accuracy.

[0124] In order to achieve the flipping of the battery cell A, in this application, see Figure 6 and Figure 7 The flipping mechanism 130 includes a base (not marked), a flip seat 131, a flip driving unit, a second clamping driving unit and a second clamping unit.

[0125] The base and the turning seat 131 are hinged, and the turning drive unit can drive the turning seat 131 to turn, wherein the turning drive unit is a turning cylinder 132 .

[0126] The flip seat 131 is provided with a second clamping driving unit and a second clamping unit, and the second clamping unit is driven by the second clamping driving unit to clamp / release the battery cell A.

[0127] The second clamping driving part is a clamping claw cylinder 133 , and the second clamping part is a pair of clamping claws 134 .

[0128] If the number of detection stations is one, for example, see Figure 4 , when only the inspection station 111 is included, the corresponding Figure 7 A clamping jaw cylinder 133 and a pair of clamping jaws 134 are provided.

[0129] If there are a first group of inspection stations 110 and a second group of inspection stations 120 as described above, and each group of inspection stations includes two inspection stations, for example, see Figure 4 The first group of inspection stations 110 includes inspection stations 111 and 112, and the second group of inspection stations 120 includes inspection stations 121 and 122. The flip seat 131 is provided with two clamping cylinders (where Figure 7 Only the clamping jaw cylinder 133) and two pairs of clamping jaws (of which Figure 7 Only one stack of clamps 134 is marked in the figure, which are used to clamp two battery cells A at the same time to improve the detection cycle.

[0130] In some embodiments of the present application, in order to improve the level of automated detection and detection rhythm, the detection of the battery cell A is connected to the battery cell production line. Therefore, a conveyor line is provided. Figure 2 and Fig. 9 .

[0131] The conveyor line 160 is used to convey the battery cells A. The conveyor line 160 has a transport position (not marked). When the battery cells A reach the transport position, a transport mechanism (not shown) can be used to transport the battery cells A at the transport position to the inspection station.

[0132] The transport mechanism may be a robot.

[0133] In order to accurately position the battery cell A at the transfer position, an in-position detection sensor (not shown) is provided on one side of the conveyor line 160 to detect whether the battery cell A reaches the transfer position.

[0134] When the battery cell A arrives at the transport position, a positioning unit (not shown) is further provided on one side of the conveyor line 160 in order to enable the transport mechanism to accurately position and transport the battery cell A.

[0135] In some embodiments of the present application, the positioning unit may be a cylinder. After detecting that the battery cell A is in place at the transport position, the cylinder is pushed out to reposition the battery cell A to ensure the accuracy of the position of the battery cell A, thereby ensuring reliable gripping by the transport mechanism.

[0136] In some embodiments of the present application, in order to trace the battery cell A, a barcode or a QR code that can be traced is also provided on the battery cell A. Correspondingly, see Figure 2 and Fig.10 The detection device is also provided with a code scanning unit 150 for scanning the battery cell A arriving at the transport position.

[0137] The code scanning unit 150 is disposed on one side of the conveying line 160 , and includes a code scanning support 151 , a pushing cylinder 152 , and a code scanning gun (not shown).

[0138] The barcode scanning gun is installed on the pushing rod 153 of the pushing cylinder 152, the pushing cylinder 152 is installed on the barcode scanning support 151, the free end of the pushing rod 153 is installed with a mounting frame 154, the mounting frame 154 is installed with the barcode scanning gun, and the barcode scanning support 151 is installed on one side of the conveyor line 160.

[0139] See also Fig.10 , where the dotted arrow shows the direction of the scanning ray emitted by one of the scanners

[0140] After the battery cell A reaches the transport position and is repositioned, the cylinder 152 pushes out the barcode scanner, so that the barcode scanner scans the battery cell A at the transport position, obtains the coding information of the battery cell A, and can upload the scanning result to the management system (not shown) to achieve product traceability.

[0141] As described above, in the present application, a first group of detection stations 110 and a second group of detection stations 120 are set, the number of detection stations in the first group of detection stations 110 and the second group of detection stations 120 are two respectively, and the first group of detection stations 110 and the second group of detection stations 120 are arranged in a straight line, see Figure 3 .

[0142] To improve the detection rhythm, see above Figures 1 to 10 As described above, the circumferential appearance surface of the battery cell A is detected at the first group of detection stations 110, and after being flipped by the flipping mechanism 130, the remaining appearance surface of the battery cell A is detected at the second group of detection stations 120, so as to match the conveying rhythm on the conveyor line 160 and realize rapid scanning.

[0143] In order to realize the flexible use of the flip mechanism 130 and to move the battery cell A from the first group of inspection stations 110 to the second group of inspection stations 120, see Figure 2 and Figure 6 The flipping mechanism 130 is arranged on a three-axis motion platform 140 .

[0144] The three-axis motion platform 140 includes an X-axis mechanism 141 , a Y-axis mechanism 142 , and a Z-axis mechanism 143 , wherein an X-axis auxiliary bracket 144 is further provided in order to stably support the three-axis motion platform 140 .

[0145] Specifically, the flipping mechanism 130 is disposed on the Z-axis mechanism 143 , and can realize three-axis movement through the three-axis motion platform 140 while the flipping mechanism 130 clamps the battery cell A with a clamp.

[0146] Correspondingly, in this case, as described above, a first scanning camera unit 171 , a second scanning camera unit 172 , and a third scanning camera unit 173 are provided.

[0147] After the scanning camera completes the scanning, the battery cell A can be moved back to the transport position by the robot arm to continue its circulation.

[0148] The process of testing the battery cell A using the testing equipment described above is described as follows.

[0149] (1) Cell A moves on conveyor line 160 and reaches the robot handling position, and cell A completes secondary positioning.

[0150] When the arrival detection sensor on the conveyor line 160 detects that both battery cells have reached the transfer position and are positioned again, the barcode scanning unit 150 is activated to complete the barcode scanning of battery cell A, and then the barcode scanning gun is withdrawn to the initial position by the push-out cylinder 152.

[0151] (3) The robot reaches above the battery cells A, grabs two battery cells A, and then moves the battery cells A in their original posture to the two inspection stations 111 / 112 of the first group of inspection stations 110.

[0152] The original posture refers to Fig. 9 The posture on the conveyor line 160, that is, see Figure 4 , with appearance surface A3 facing upward.

[0153] (4) When the sensor detects that the battery cell A reaches the first group of inspection stations 110, the clamps on the inspection stations 111 / 112 in the first group of inspection stations 110 clamp the battery cell A, and then release the battery cell A. Driven by the lifting cylinder 1114, the battery cell A descends to the avoidance height, and the first scanning camera unit 171 and the second scanning camera unit 172 on both sides are activated to detect the appearance surfaces of the two battery cells A facing the first scanning camera unit 171 and the second scanning camera unit 172. The appearance surfaces detected here are the appearance surface A1 of each battery cell A and the appearance surface opposite to the appearance surface A1.

[0154] (5) After the scanning is completed, the clamp is driven by the lifting cylinder 1114 to rise to the working height and clamp the battery cell A. The rotating cylinder 1112 drives the battery cell A to rotate 90°. After the rotation is completed, the clamp releases the battery cell A and is driven by the lifting cylinder 1114 to descend to the avoidance height to avoid blocking the appearance surface. The first scanning camera unit 171 and the second scanning camera unit 172 on both sides are activated to detect the appearance surfaces of the two battery cells A facing the first scanning camera unit 171 and the second scanning camera unit 172. The appearance surfaces detected here are appearance surface A2 and the appearance surface opposite to A2.

[0155] As described above (1) to (5), the circumferential appearance surface of the battery cell A is scanned at the first group of inspection stations 110 .

[0156] (6) After the inspection is completed, the clamping jaws are driven by the lifting cylinder 1114 to rise to the working height, clamp the battery cell A, and the rotating cylinder 1112 rotates the battery cell A 90° in the opposite direction to return to the original posture when loading.

[0157] (7) After the inspection is completed at the first inspection station 110, the flipping mechanism 130 grabs the battery cell A at the first inspection station 110, and then operates to flip the battery cell A 90°. After flipping, the battery cell A is placed at the second inspection station 120.

[0158] (8) The clamps on the second inspection station 120 clamp the battery cell A and then release the battery cell A. The battery cell A is driven by the lifting cylinder 1114 to descend to the avoidance height. The third scanning camera unit 173 on one side is activated to inspect the appearance surfaces of the two battery cells A facing the third scanning camera unit 173. The appearance surface inspected here is appearance surface A3.

[0159] (9) After the detection is completed, the rotating cylinder 1112 rotates the battery cell A 180°, and the third scanning camera unit 173 is activated. The appearance surface of the third scanning camera unit 173 is detected here, which is the appearance surface opposite to A3.

[0160] The scanning of the remaining appearance surface of the battery cell A is completed at the second inspection station 120 as described in (6) to (9).

[0161] (10) After the second inspection station 120 completes the inspection, the flipping mechanism 130 grabs the battery cell A, flips the battery cell A back to its original position when it was loaded, and then flows out.

[0162] The polyhedron appearance surface detection device 100 involved in the present application can be connected to the production line of battery cell A without delaying the production rhythm of battery cell A. The rotating mechanism and the flipping mechanism 130 can be used to automatically switch between multiple appearance surfaces of battery cell A, thereby improving the operating speed, saving operating time, and facilitating the scanning camera unit 170 to scan its appearance surface.
