Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to a testing device. Background Technology

[0002] In battery manufacturing, to ensure product yield, testing equipment is needed to test battery components and other materials. Only materials that pass the test can be used.

[0003] To achieve thorough material testing, the testing equipment requires a relatively long conveyor line with various testing stations arranged along it. This places high demands on the dimensional requirements of the installation space in one direction, making deployment difficult. This is especially problematic when applying the testing equipment to existing production lines, where the available space is often limited to gaps. If the conveyor line is too long, installation becomes impossible; conversely, if the conveyor line is too short, too few detectors can be installed, hindering thorough material testing. Summary of the Invention

[0056] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0057] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0058] Furthermore, where the term "and / or" appears, it merely describes the relationship between related objects and indicates that three relationships can exist. For example, A and / or B can represent the relationship between A and B: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates an "or" relationship between the related objects before and after it. Where the terms "first" and "second" appear, these terms are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature specified with "first" or "second" may explicitly or implicitly include at least one of those features. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, four, five, etc., unless otherwise explicitly specified.

[0059] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0060] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0061] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0062] Please see Figures 1 to 7 An embodiment of the present application provides a detection device 1, which includes a detection section 10. The detection section 10 includes a conveying assembly 100, at least one flipping mechanism 200, and at least two sets of detection assemblies 300.

[0063] Conveying assembly 100 includes at least one handling device 110 and at least two conveyor belts 130, all of which are along a first direction (e.g., Figure 3 The conveyor belts 130 are arranged in an X-direction and connected end-to-end by a conveying device 110 to form a conveyor line. The longitudinal direction of each conveyor belt 130 intersects the first direction. The conveyor line has at least one turning station and at least two inspection stations. All turning mechanisms 200 are respectively located at each turning station and are used to turn the material 2 on the conveyor belt 130. All inspection components 300 are respectively located at each inspection station; all inspection stations include a first inspection station and a second inspection station, and there are n turning stations between the first inspection station and the second inspection station, where n is an odd number.

[0064] The arrangement of all conveyor belts 130 along the first direction means that the projections of adjacent conveyor belts 130 along the first direction at least partially overlap, and the conveyor line extends in a meandering manner. In a specific embodiment, the longitudinal direction of all conveyor belts 130 is perpendicular to the first direction, all conveyor belts 130 are parallel to each other, and at least one end is aligned to achieve a compact arrangement.

[0065] Understandably, the conveying device 110 is used to transport material 2 from one conveyor belt 130 to another. Specifically, each conveying device 110 is located at the tail end of one conveyor belt 130 and the beginning end of an adjacent conveyor belt 130, so as to transport material 2 from the tail end of the conveyor belt 130 to the beginning end of the adjacent conveyor belt 130 for continued transport. Therefore, the number of conveying devices 110 is one less than the number of conveyor belts 130. In other words, each conveying device 110 is located at the tail end of one conveyor belt 130 and the beginning end of an adjacent conveyor belt 130, and is used to transport material 2 from the upstream conveyor belt 130 to the downstream conveyor belt 130, realizing the transfer of material 2 between different conveyor belts 130. Therefore, with the connection of the conveying devices 110, all conveyor belts 130 can form a conveyor line, allowing material 2 to be transported sequentially through all conveyor belts 130.

[0066] In addition, the conveyor line has multiple stations, including a flipping station and an inspection station. All stations can be located on the same conveyor belt 130 or on different conveyor belts 130. All conveyor belts 130 can have stations, or only some conveyor belts 130 can have stations, etc., without specific limitations.

[0067] The flipping mechanism 200 can flip the material 2 at a flipping angle of 180°, so as to flip the side of the material 2 facing the conveyor belt 130 to the side facing away from the conveyor belt 130. Each flipping station is provided with a flipping mechanism 200 so that the material 2 can be flipped after being conveyed to the flipping station.

[0068] The detection component 300 is used to detect the side of material 2 facing away from the conveyor belt 130. Since n (n can be, but is not limited to, 1 or 3) is an odd number, in a specific embodiment, n is 1. Before and after the material 2 is flipped by the full-fledged flipping mechanism 200 between the first and second detection stations, the side of material 2 facing away from the conveyor belt 130 changes. The detection component 300 at the first detection station can perform detection including detection of the first side of material 2, and the detection component 300 at the second detection station can perform detection including detection of the second side of material 2. One of the first and second sides is the front side of material 2, and the other is the back side of material 2.

[0069] In one embodiment, material 2 is a battery cover. In other embodiments, material 2 may also be a battery casing, etc., and is not specifically limited here.

[0070] The aforementioned testing equipment 1 comprises multiple conveyor belts 130 arranged in a conveyor line, with material 2 transferred between the conveyor belts 130 via a handling device 110. This shortens the length of the conveyor line in a single direction without altering its overall length. Simultaneously, the material 2 can be flipped during transport, and its front and back sides can be inspected using testing components 300 located upstream and downstream of a flipping station. Each testing component 300 and related structure can be arranged on different conveyor belts 130, enabling thorough inspection of the material 2. Furthermore, the testing equipment 1 exhibits high overall compactness and requires less space in a single direction.

[0071] In some embodiments, the conveyor line further includes two cleaning stations, and m flipping stations between the two cleaning stations, where m is an odd number. The detection section 10 also includes two cleaning mechanisms 400, which are respectively located at the two cleaning stations.

[0072] Understandably, m can be, but is not limited to, 1, 3, etc. In one specific embodiment, m is 1. Since m is an odd number, the side of material 2 facing away from the conveyor belt 130 changes before and after the material 2 is flipped by the full flipping mechanism 200 between the two cleaning stations.

[0073] Thus, the cleaning mechanism 400 is used to clean the material 2 located at the cleaning station, and the two cleaning mechanisms 400 can clean the front and back of the material 2 respectively.

[0074] Furthermore, the cleaning mechanism 400 includes a plasma generator 410, a gas collection hood 430, and an extraction structure 450. The output end of the plasma generator 410 is connected to the gas collection hood 430. The gas collection hood 430 has an inlet and an outlet located opposite to each other outside the conveyor belt 130 and in the direction of conveying the material 2 on the conveyor line. The extraction structure 450 is connected to the gas collection hood 430 and is used to extract the gas inside for harmless treatment.

[0075] Understandably, the plasma generator 410 can generate plasma and output it to the gas collection hood 430 through the output end. Material 2 can be input into the gas collection hood 430 through the inlet along with the conveyor belt 130, and be cleaned by the plasma generated by the plasma generator 410. After cleaning, it can be output from the outlet along with the conveyor belt.

[0076] In this way, the cleaning unit 400 can perform plasma cleaning on the material 2 at the cleaning station, achieving efficient cleaning with minimal impact on the conveying of the material 2.

[0077] In some embodiments, the gas collecting hood 430 has an elongated hole 431, the longitudinal extension direction of which intersects the longitudinal direction of the conveyor belt 130. The output end is connected to the gas collecting hood 430 through the elongated hole 431 and can move along the elongated hole 431. Specifically, the longitudinal extension direction of the elongated hole 431 may be consistent with the width direction of the conveyor belt 130.

[0078] Thus, the plasma generator 410 can be moved so that its output end moves along the elongated hole 431 to sweep across the material 2 on the conveyor belt 130 laterally, thereby achieving thorough cleaning.

[0079] In some embodiments, the two cleaning stations are located on the two conveyor belts 130, respectively. The detection section 10 also includes a cleaning drive mechanism 500, which is driveably connected to the two cleaning mechanisms 400 and configured to drive the two cleaning mechanisms 400 to move in a direction intersecting the conveyor belts 130.

[0080] Specifically, two cleaning stations can be arranged side by side on two adjacent conveyor belts 130. The cleaning drive mechanism 500 is located above the two conveyor belts 130. The cleaning mechanism 400 is connected to the cleaning drive mechanism 500 so as to move under its drive.

[0081] In this way, a single cleaning drive mechanism 500 can simultaneously drive two cleaning mechanisms 400 to scan and clean the material 2, which helps to simplify the overall structure of the detection equipment 1.

[0082] In one specific embodiment, the detection section 10 may include at least two handling devices 110 and at least three conveyor belts 130. In another specific embodiment, the detection section 10 includes two handling devices 110 and three conveyor belts 130, which are a first conveyor belt 136, a second conveyor belt 137, and a third conveyor belt 138 arranged sequentially in a first direction. The first conveyor belt 136 has a first detection station and a cleaning station, the second conveyor belt 137 has another cleaning station, and the third conveyor belt 138 has a second detection station. Furthermore, the first conveyor belt 136 and the third conveyor belt 138 also have other detection stations, and correspondingly, detection components 300 are provided. Thus, all detection stations are located on the two conveyor belts 130 at both ends in the first direction, facilitating maintenance.

[0083] In some embodiments, each conveyor belt 130 includes two sub-belts 131, which are parallel and spaced apart, and a turning mechanism 200 is disposed between the two sub-belts 131.

[0084] Thus, the overturning mechanism 200 is installed in the space between the two sub-belts 131, which reduces the space occupied on both sides of the conveyor belt 130. On the other hand, the two ends of the material 2 can be placed on the two sub-belts 131 for conveying. The part located between the two sub-belts 131 makes it easier for the overturning mechanism 200 to capture and overturn the material 2 more accurately, and can reduce the probability of interference between the overturning mechanism 200 and the conveyor belt 130.

[0085] In some embodiments, the spacing between the two sub-belts 131 is configured to be adjustable.

[0086] Thus, the conveyor belt 130 can be better adapted to materials 2 of different sizes by adjusting the spacing between the two sub-belts 131.

[0087] Specifically, the conveyor belt 130 also includes a mounting frame 133 and a mounting rail 135. The mounting frame 133 is slidably mounted on the mounting rail 135, and the sub-belts 131 are mounted on the mounting frame 133. The spacing between the two sub-belts 131 is adjusted by relative sliding of the mounting frame 133.

[0088] In addition, the conveyor belt 130 may also include a scale and a pointer. The scale is set on the guide rail, and the pointer is set on the mounting frame 133 and points to the scale. The scale pointed to by the pointer changes accordingly as the mounting frame 133 slides relative to the scale. The scale pointed to by the pointer represents the position of the mounting frame 133 and also corresponds to the position of the sub-belt 131, so that the operator can accurately know the current distance between the two sub-belts 131.

[0089] In some embodiments, the conveyor line has two flipping stations, and the testing device 1 includes two flipping mechanisms 200, which are respectively located at the two flipping stations. Accordingly, there is one and only one flipping station between the first testing station and the second testing station.

[0090] In this way, the testing equipment 1 can flip the material 2 once through a flipping mechanism 200 and then flip it a second time through another mechanism, so that the front and back of the material 2 can be restored to the initial state. This helps to improve the consistency of the input and output of the material 2 of the testing equipment 1, and makes the input and output of the material 2 of the testing equipment 1 consistent after it is connected to the production line, so that the material 2 can be passed downstream.

[0091] Please refer to the following: Figure 8 In some embodiments, the flipping mechanism 200 includes a flipping arm 210 and a flipping driver 230. The flipping arm 210 is disposed on the moving path of the material 2 and has a receiving groove 211 capable of accommodating the material 2.

[0092] The tilting drive 230 is driven by the tilting arm 210 and is configured to drive the tilting arm 210 to rotate and flip around a tilting axis that is parallel to the horizontal direction and perpendicular to the conveying direction of the conveyor belt 130. The tilting arm 210 is configured to flip so that the opening edge of its receiving slot 211 faces the material 2 under the drive of the tilting drive 230.

[0093] Specifically, the tilting arm 210 has a receiving position and a discharging position, and can switch between the receiving position and the discharging position by tilting. When tilted to the receiving position, it can receive material 2 into the receiving tank 211 through the slot, and when tilted to the discharging position, it can release material 2 through the slot.

[0094] Thus, the tilting arm 210 can rotate to face the material 2 located upstream of it. The material 2 located upstream of it can be moved from the trough opening to the receiving trough 211 of the tilting arm 210 in the receiving position under the conveyor belt 130. The tilting driver 230 drives the tilting arm 210 to rotate 180° and fall back onto the conveyor belt 130. The material 2 is flipped and, under the conveyor belt 130, leaves the receiving trough 211 from the trough opening and continues to be transported.

[0095] In some embodiments, the flipping mechanism 200 is configured to be height-adjustable so that the flipping arm 210 can be flush with the material 2 when the opening of its receiving slot 211 is facing the material 2, so as to better receive the material 2.

[0096] In some embodiments, the flipping mechanism 200 includes two flipping arms 210, with an included angle of 180° between the two flipping arms 210, and the flipping driver 230 synchronously drives the two arms to flip. Specifically, the two flipping arms 210 can be separate structures or integrally connected.

[0097] In this way, the flipping drive 230 can drive the two flipping arms 210 to flip along a single direction, and the two flipping arms 210 alternately flip the material. Every time they flip 180°, one of the two flipping arms 210 can face and receive the material 2 located upstream, while the other completes the flipping of the material 2 and releases the material 2 downstream, thereby improving the efficiency of flipping the material 2.

[0098] Specifically, each tilting arm 210 may include two sub-arms, which are spaced apart to improve the stability of receiving and tilting the material 2.

[0099] In some embodiments, the flipping mechanism 200 further includes a feed sensor 250 and a discharge sensor 270, which are respectively disposed on both sides of the flipping axis in the conveying direction and electrically connected to the flipping driver 230.

[0100] Specifically, the feed sensor 250 is set in the receiving groove 211 of the tilting arm 210 located at the receiving position to sense whether material 2 has entered the receiving groove 211, and the discharge sensor 270 is set in the receiving groove 211 of the tilting arm 210 located at the discharging position to sense whether material 2 has left the receiving groove 211.

[0101] Thus, the flipping mechanism 200 can detect the material receiving and releasing status of the flipping arm 210 through the feed sensor 250 and the discharge sensor 270, and control the flipping driver 230 accordingly to improve the accuracy of the flipping mechanism 200.

[0102] In some embodiments, the flipping mechanism 200 includes at least two sizes of flipping arms 210, which are detachably connected to the flipping driver 230.

[0103] Understandably, each specification of the tilting arm 210 can be set in pairs and installed in pairs. Specifically, the different specifications of the tilting arm 210 mainly refer to the different sizes of the receiving groove 211.

[0104] Thus, the flipping mechanism 200 can be adapted to materials 2 of different sizes by replacing the flipping arm 210 of different specifications, thereby improving the versatility of the detection equipment 1.

[0105] In some embodiments, the detection section 10 further includes a dual detection drive 600, which includes a moving rail 610 and a moving block 630. The moving rail 610 is longitudinally arranged along the direction intersecting the conveyor belt 130, located above the conveyor belt 130, and positioned between two adjacent detection stations. The moving block 630 is slidably disposed on the moving rail 610 and connected to the detection components 300 corresponding to the detection stations on both sides of the moving rail 610.

[0106] In other words, the moving rail 610 is located between two adjacent inspection stations, and the moving block 630 on it connects the inspection components 300 at both inspection stations. The longitudinal direction of the moving rail 610 can be consistent with the width direction of the conveyor belt 130.

[0107] Thus, the dual detection drive unit 600 can drive the detection assembly 300 to move laterally to scan the material 2, achieving the purpose of thorough detection. At the same time, each dual detection drive unit 600 can drive two sets of detection assemblies 300, which helps to simplify the structure of the detection equipment 1.

[0108] In some embodiments, the detection section 10 may further include a single detection drive 700, each single detection drive 700 being drively connected to a group of detection components 300 to drive the detection components 300 to move in a direction intersecting with the conveyor belt 130.

[0109] In some embodiments, all inspection stations include a 3D inspection station, and all inspection components 300 include a 3D camera inspection component 310, which is disposed at the 3D inspection station. The inspection section 10 also includes a lifting mechanism, which is disposed at the 3D inspection station and is used to drive the material 2 located at the 3D inspection station to move up and down.

[0110] In this way, the lifting mechanism can drive the material 2 to move up and down so that it can be scanned and detected more fully by the 3D camera detection component 310.

[0111] In some embodiments, the entire detection assembly 300 also includes an injection hole detection assembly 330 and a protective shell. The protective shell covers the injection hole detection assembly 330 and can protect the injection hole detection assembly 330 and reduce damage caused by external structural collisions.

[0112] In some embodiments, the detection unit 10 further includes a side-mounted camera 800, which is located on one side of the material movement path of the material 2 being transported by the conveying device 110.

[0113] Thus, the side-mounted camera 800 can detect the side of material 2, which helps to improve the detection sufficiency of the detection device 1. At the same time, the side-mounted camera 800 can complete the scanning and detection of the side of material 2 during the process of material 2 being transported by the conveying device 110, without the need for additional drive components to achieve mobile scanning, thereby reducing the introduction of new drive mechanisms.

[0114] For the inspection of the cover plate, the inspection component 300 located at the first inspection station can perform inspections such as pole detection, injection molding, and edge rolling, while the inspection component 300 located at the second inspection station can perform inspections such as large surface detection and pole detection. All inspection components 300 may also include a short-surface inspection component 350, which is located on one side of the conveyor belt 130 and can complete the scanning inspection of the side of the cover plate during the conveyor belt 130's transport of the cover plate. Specifically, all inspection components 300 may also include two sets of short-surface inspection components 350, which are used to inspect opposite sides of the cover plate respectively. In addition, all inspection components 300 may also include other pole detection components, etc., which are not specifically limited here.

[0115] Please refer to the following: Figures 9 to 11In some embodiments, each conveying device 110 includes a base 111, a first drive assembly 113, and two gripping mechanisms 115. The base 111 has a first position and a second position spaced apart in a first direction. The two gripping mechanisms 115 are movably disposed on the base 111. The first drive assembly 113 is drively connected to the two gripping mechanisms 115 and configured to drive the two gripping mechanisms 115 to move between the first position and the second position, such that when one of the two gripping mechanisms 115 is in the first position, the other is in the second position. Correspondingly, when one of the two gripping mechanisms 115 is in the second position, the other is in the first position.

[0116] The first position on the base 111 corresponds to one conveyor belt 130, and the second position corresponds to another conveyor belt 130. When the gripping mechanism 115 moves to the first position on the base 111, it can grip the material 2 on the conveyor belt 130 corresponding to the first position, and when it moves to the second position, it places the material 2 on the conveyor belt 130 corresponding to the second position.

[0117] Thus, each conveying device 110 has two gripping mechanisms 115, and the two gripping mechanisms 115, driven by the first drive assembly 113, can alternately move to a first position to pick up material and alternately move to a second position to release material on the base 111. In this way, the material 2 can be transferred more continuously between the two conveyor belts 130. Each time the gripping mechanism 115 picks up material on one conveyor belt 130, another gripping mechanism 115 releases material on the other conveyor belt 130, and the process is repeated alternately to achieve dual-station conveying, which significantly improves the conveying efficiency of the material 2 between the conveyor belts 130.

[0118] In some embodiments, the first drive assembly 113 includes a first driver 1131 and a synchronous transmission mechanism 1133. The first driver 1131 is driveably connected to two gripping mechanisms 115 via the synchronous transmission mechanism 1133. The synchronous transmission mechanism 1133 is configured to synchronously drive the two gripping mechanisms 115 to move in opposite directions under the drive of the first driver 1131.

[0119] In other words, the first driver 1131 drives the two gripping mechanisms 115 to move between the first position and the second position through the synchronous transmission mechanism 1133, and under the transmission action of the synchronous transmission mechanism 1133, the two gripping mechanisms 115 move in opposite directions, that is, one moves from the first position to the second position, and the other moves from the second position to the first position.

[0120] Thus, under the transmission of the synchronous transmission mechanism 1133, the first driver 1131 can simultaneously drive the two gripping mechanisms 115, and make them move alternately from the first position to the second position and from the second position to the first position, so as to ensure that when one of them is in the first position, the other is in the second position.

[0121] Furthermore, the synchronous transmission mechanism 1133 includes a transmission belt 11331 and at least two pulleys 11333. At least one of the pulleys 11333 is a drive pulley, which is connected to the first driver 1131. The transmission belt 11331 passes around all the pulleys 11333 and has a first portion and a second portion arranged opposite to each other. Both the first portion and the second portion are parallel to a first direction, and two gripping mechanisms 115 are respectively connected to the first portion and the second portion.

[0122] Understandably, the transmission belt 11331 is a closed flexible belt capable of bidirectional force transmission. Specifically, the transmission belt 11331 can also be a chain, etc., as long as it can move around all the pulleys 11333 under the drive of the drive pulleys and drive the two gripping mechanisms 115 connected to it to move. No specific limitation is made here.

[0123] Driven by the drive pulleys, the transmission belt 11331 can move around all the pulleys 11333, thereby driving the gripping mechanism 115 connected to it to move. Therefore, the first part and the second part of the transmission belt 11331 only refer to the parts corresponding to the opposite sides, and do not specifically refer to a certain part of the transmission belt 11331. Accordingly, the connection points of the two gripping mechanisms 115 on the transmission belt 11331 are the first connection point and the second connection point, respectively. The first connection point is always located in the first part, and the second connection point is always located in the second part. During the movement of the transmission belt 11331, the positions of the two mechanisms change within the first part and the second part, respectively.

[0124] Thus, driven by the first driver 1131, the drive slides and rotates, and synchronously drives the gripping mechanisms 115 located on both sides to move through the transmission belt 11331. Since both are driven by the same transmission belt 11331 and are in opposite positions, they can naturally form synchronous and opposite movements.

[0125] In other embodiments, the synchronous transmission mechanism 1133 may also be composed of other structures, such as a gear and two racks, with the gear being connected to the first driver 1131. The two racks are parallel to the first direction and are located on both sides of the gear. The two gripping mechanisms 115 are respectively connected to the two racks. It is only necessary to be able to drive the two gripping mechanisms 115 to move synchronously and in opposite directions, and no specific limitation is made here.

[0126] In some embodiments, each gripping mechanism 115 includes a second drive assembly 1151 and a gripping member 1153. The second drive assembly 1151 is driveably connected to the gripping member 1153 and is configured to drive the gripping member 1153 along a second direction (e.g., Figure 10 The movement is in the Z direction (as shown), and the second direction intersects with the first direction.

[0127] Specifically, the second direction can be the direction of gravity, that is, the height direction of the conveying device 110. The conveying device 110 may also include a support leg 117, and the base 111 is fixed above the conveyor belt 130 by the support leg 117.

[0128] Thus, the gripping mechanism 115 can drive the gripping member 1153 to rise and fall via the second drive assembly 1151, so as to pick up and drop materials above the conveyor belt 130 by lifting and lowering.

[0129] Specifically, the gripper 1153 is a suction cup. In some other embodiments, the gripper 1153 may also be a clamp or the like.

[0130] In some embodiments, the two gripping mechanisms 115 are respectively located on the base 111 in a third direction (e.g., Figure 11 (As shown in the Y direction) on opposite sides. The gripping elements 1153 of the two gripping mechanisms 115 are aligned in the third direction, and intersect each other in the first direction, the second direction, and the third direction. When the first drive assembly 113 drives the two gripping mechanisms 115 to move between the first position and the second position, the second drive assembly 1151 of the two gripping mechanisms 115 drives the gripping elements 1153 of both to be misaligned in the second direction.

[0131] Specifically, the first direction, the second direction, and the third direction are perpendicular to each other, and the third direction can also be the horizontal direction.

[0132] Thus, the two gripping mechanisms 115 are located on both sides of the base 111, allowing them to move better along the first direction while avoiding mutual interference.

[0133] The gripping parts 1153 of the two gripping mechanisms 115 are aligned in the third direction, indicating that when they move to the same position in the first and second directions, they are in the same position because they are also aligned in the third direction. In short, the gripping parts 1153 of the two gripping mechanisms 115 can pick up and unload materials at the same position on the conveyor belt 130, ensuring consistent handling of material 2. Meanwhile, to prevent interference between the gripping parts 1153 of the two gripping mechanisms 115 during movement, the second drive assembly 1151 can drive them to be at different heights and offset from each other.

[0134] In some embodiments, each gripping mechanism 115 further includes a gripping arm, which includes a connected longitudinal arm and a transverse arm. The longitudinal arm is located on the third-direction side of the base 111 and is drively connected to the second drive assembly 1151. The transverse arm extends along the third-direction, and a gripping member 1153 is disposed on the transverse arm.

[0135] Thus, the longitudinal arm is used for sliding engagement with the base 111, while the transverse arm extends laterally to provide a mounting position for the gripper 1153. Understandably, the transverse arms of the two gripping mechanisms 115 extend toward each other, and at least partially overlap in a third direction, so that the grippers 1153 of the two gripping mechanisms 115 can be aligned in the third direction.

[0136] Specifically, each gripping mechanism 115 may include two gripping arms spaced apart, and each gripping arm may have two gripping elements 1153 on its horizontal arm portion to improve the gripping stability of the material 2.

[0137] In some embodiments, the gripper 1153 has a first misaligned position and a second misaligned position spaced apart from each other on the movement path in the second direction.

[0138] Each gripping mechanism 115 further includes a first sensor 34 and a second sensor 34. The first sensor 34 is configured to be triggered when the gripper 1153 is in a first misaligned position, and the second sensor 34 is configured to be triggered when the gripper 1153 is in a second misaligned position.

[0139] The second drive assembly 1151 is electrically connected to the first sensor 34 and the second sensor 34. When the first drive assembly 113 drives the two gripping mechanisms 115 to move between the first position and the second position, the second drive assembly 1151 of one of the two gripping mechanisms 115 drives its gripping member 1153 to trigger the first sensor 34, and the second drive assembly 1151 of the other drives its gripping member 1153 to trigger the second sensor 34.

[0140] Understandably, the second drive assembly 1151 can be directly or indirectly electrically connected to the first sensor 34 and the second sensor 34, and control the gripper 1153 to work based on the detection signals of both.

[0141] Thus, when the first drive assembly 113 drives the two gripping mechanisms 115 to move between the first position and the second position, the second drive assemblies 1151 of the two mechanisms drive their gripping parts 1153 to trigger the first sensor 34 and the second sensor 34 respectively, so that the gripping parts 1153 of the two mechanisms are misaligned in the second direction when they are in the first misaligned position and the second misaligned position respectively.

[0142] Furthermore, the gripper 1153 also has pick-up and drop-off positions spaced apart from the first and second misaligned positions on its movement path in the second direction. Each gripping mechanism 115 also includes a third sensor 34, and the second drive assembly 1151 is also electrically connected to the third sensor. The third sensor 34 is configured to be triggered when the gripper 1153 is in the pick-up and drop-off position.

[0143] Specifically, the first misaligned position, the second misaligned position, and the material pick-up and drop-off position are set in order from high to low. When the gripping parts 1153 of the two gripping mechanisms 115 are in the first misaligned position and the second misaligned position respectively, they are misaligned with each other. When in the material pick-up and drop-off position, they grip the material 2 on the conveyor belt 130 or place the material 2 on the conveyor belt 130.

[0144] Specifically, the gripping mechanism 115 has a sensing unit, with a first sensor, a second sensor, and a third sensor sequentially arranged on the moving path of the sensing unit. Specifically, the first sensor, the second sensor, and the third sensor can all be photoelectric switches, and the sensing unit can move between the sensing part and the transmitting part of the photoelectric switch to trigger the photoelectric switch.

[0145] In other embodiments, the first sensor, the second sensor, and the third sensor may also be Hall sensors, infrared sensors, acoustic switches, etc., which are not specifically limited here.

[0146] Please refer to the following: Figures 12 to 14 In some embodiments, the conveyor line also has a loading station. The detection device 1 further includes a loading mechanism 30, and the detection section 10 further includes a picking mechanism 900. The loading mechanism 30 is located at the loading station and includes a loading conveyor belt and a limiting member 32. The loading conveyor belt has a picking position 311 and an adjacent position 313; the adjacent position 313 is adjacent to the picking position 311, and in the conveying direction of the material 2, the adjacent position 313 is located upstream of the picking position 311. The limiting member 32 is located above the loading conveyor belt and at the adjacent position 313. The end of the limiting member 32 near the loading conveyor belt is a limiting end 321. In the direction of gravity, the limiting end 321 is spaced apart from the loading conveyor belt and is used to limit the material 2 located at the adjacent position 313 on the loading conveyor belt in the direction of gravity. The material handling mechanism 900 is located at the loading station and is used to transfer the material 2 located at the material handling position 311 on the loading conveyor belt to the conveyor belt 130.

[0147] The feeding mechanism 30 is used to convey material 2 to the detection section 10 for detection. Understandably, the feeding conveyor belt is used to transport material 2, and the material 2 transported thereon can sequentially reach adjacent position 313 and picking position 311. In other words, material 2, conveyed by the feeding conveyor belt, arrives at picking position 311 via adjacent position 313. Material 2 located at picking position 311 can be picked up by picking mechanism 900, and material 2 located at adjacent position 313 is adjacent to material 2 located at picking position 311.

[0148] The number of materials 2 that can be accommodated at the picking position 311 depends on the number of materials that the picking mechanism 900 can pick up at one time. For example, if the picking mechanism 900 can pick up two adjacent materials 2 at one time, then the picking position 311 can accommodate two materials 2. The adjacent position 313 can only accommodate a single material 2. In summary, the coverage area of ​​the picking position 311 and the adjacent position 313 can be determined by the size of the material 2 to be conveyed by the feeding conveyor belt and the number of materials 2 that need to be accommodated at that position.

[0149] The limiting member 32 is positioned above the feeding conveyor belt in the direction of gravity, and correspondingly, the material 2 at the adjacent position 313 is positioned below the limiting member 32. Limiting the material 2 at the adjacent position 313 on the feeding conveyor belt in the direction of gravity means that the limiting member 32 can prevent the material 2 from moving upwards through the limiting end 321. The limiting end 321 is spaced apart from the feeding conveyor belt so that the material 2 can smoothly pass through the limiting member 32 through the gap between them and reach the picking position 311. Specifically, the gap between the limiting end 321 and the feeding conveyor belt can be approximately the same as or slightly greater than the thickness of the material 2, so that it does not obstruct the material 2 in the direction of material 2's transport. The limiting end 321 has a guide angle on the upstream side in the direction of material 2's transport, which guides the material 2 into the space between the limiting end 321 and the feeding conveyor belt.

[0150] The material handling mechanism 900 is configured to rotate so as to place materials 2 with different incoming directions from the feeding conveyor belt onto the conveyor belt 130 by rotation, and the material handling mechanism 900 can handle two or more materials 2 at a time.

[0151] Thus, the feeding mechanism 30 can convey material 2 to the detection section 10 of the detection equipment 1 via the conveyor belt 130. When the picking mechanism 900 of the detection section 10 grabs the material 2 located at the picking position 311 and lifts it upwards, the limiting member 32 can block the material 2 located at the adjacent position 313 above through its limiting end 321, so as to prevent it from being significantly lifted by the material 2 taken away by the picking mechanism 900. In this way, under the limitation of the limiting member 32, the position of the upstream material 2 adjacent to the material 2 taken away by the picking mechanism 900 is more stable, and the risk of falling is reduced.

[0152] In some embodiments, the feeding mechanism 30 includes two limiting members 32, which are spaced apart in the width direction of the feeding conveyor belt. Specifically, the two limiting members 32 can be symmetrically arranged with the center line of the feeding conveyor belt as the axis of symmetry.

[0153] In this way, the limiting component 32 can limit the material 2 at intervals in the width direction of the feeding conveyor belt, reducing the probability that the material 2 will be carried up by one side.

[0154] In some embodiments, the limiting member 32 is configured to adjust its position along the material 2 conveying direction.

[0155] Thus, the limiting member 32 can adjust its position to accurately position itself at the adjacent position 313 and can adapt to different materials 2.

[0156] In some embodiments, the feeding mechanism 30 further includes a positioning member 33, which is disposed on both sides of the feeding conveyor belt in the width direction and located at the picking position 311, and is used to position the material 2 at the picking position 311 in the width direction of the feeding conveyor belt.

[0157] Thus, the positioning component 33 can perform secondary positioning of the material 2 in the picking position 311 in the width direction, so that it is accurately positioned in the picking position 311 so that the picking mechanism 900 can grasp it.

[0158] In some embodiments, the feeding mechanism 30 further includes a sensor 34, which is located upstream of the material pick-up position 311 in the material 2 conveying direction.

[0159] The sensor 34 is configured to be triggered by material 2 passing through it in the material 2 transport direction.

[0160] Thus, the sensor 34 can be triggered by the passing material 2, thereby recording the number of passing material 2, and correspondingly reflecting the number of material 2 entering the picking position 311, so that the picking mechanism 900 can pick up the material after the picking quantity is reached.

[0161] Specifically, the sensing element 34 is a photoelectric switch installed on both sides of the feeding conveyor belt, and can be located at the adjacent position 313. The photoelectric switch can emit photoelectric light, and when the material 2 passes by and blocks the photoelectric light, the photoelectric switch is triggered.

[0162] In some embodiments, the feeding mechanism 30 further includes two guide members 35, which are respectively disposed on both sides of the feeding conveyor belt in the width direction and are used to guide the material 2 to the adjacent position 313 and the picking position 311.

[0163] In this way, the guide 35 can guide the material 2 to flow accurately to the adjacent position 313 and the picking position 311, reducing the probability of the material 2 getting stuck outside the feeding mechanism 30.

[0164] Specifically, at least one of the two guide members 35 has an upstream end 351 in the material conveying direction 2, and the inlet end 351 has an inlet surface 3511 that is inclined toward the feeding conveyor belt in the material conveying direction 2. In addition, the lengths and shapes of the two guide members 35 may be different.

[0165] In some embodiments, the feeding mechanism 30 further includes a stop member 36, which is located downstream of the material pick-up position 311 in the material 2 conveying direction and is used to stop the material 2 at the material pick-up position 311.

[0166] Thus, the stop 36 can block the material 2 that has reached the picking position 311 to prevent it from continuing to be conveyed forward, so that the material 2 stops at the picking position 311 so that the picking mechanism 900 of the detection section 10 can pick up the material.

[0167] In some embodiments, at least one of the limiting member 32, the stop member 36, and the guide member 35 is made of a non-metallic material, specifically plastic, rubber, wood, or silicone.

[0168] Specifically, the limiting component 32, the stop component 36, and the guide component 35 can all be made of non-metallic materials such as plastic, rubber, wood, or silicone.

[0169] Thus, compared to the metal material of the cover plate, non-metallic materials such as plastic, rubber, wood and silicone have lower hardness. The limiting part 32, the stop part 36 and the guide part 35 may come into direct contact with the material 2 and even generate interaction forces. Using such materials can produce a certain buffering effect when colliding with the material 2, reducing the probability of the material 2 being damaged or scratched.

[0170] In some embodiments, the spacing between the two guides 35 in the width direction of the feeding conveyor belt is configured to be adjustable.

[0171] In this way, the user can adjust the two guides 35 to a suitable distance according to the size of the conveyed material 2. Therefore, the feeding mechanism 30 can better adapt to materials 2 of different sizes.

[0172] Please refer to the following: Figures 15 to 18 In some embodiments, the detection device 1 further includes a feeding section 50, which is located downstream of the conveyor line in the direction of conveying the material 2 and is used to receive the material 2 conveyed by the conveyor line.

[0173] The feeding section 50 includes at least one feeding port structure 51, each feeding port structure 51 including an empty tray positioning mechanism 511 and two outlet guide plates 513. The two outlet guide plates 513 are spaced apart and define an outlet 515 between them. The empty tray positioning mechanism 511 is fixed to the top of the outlet guide plate 513.

[0174] The empty tray positioning mechanism 511 is used to position the empty tray. The discharge port structure 51 may also include a mounting sheet metal 517, which is connected between two outlet guide plates 513 and is used to mount the empty tray positioning mechanism 511.

[0175] Thus, the empty disc positioning mechanism 511 is directly fixedly installed on the outlet guide plate 513, which simplifies the discharge port structure 51 and helps to reduce costs.

[0176] Specifically, the unloading section 50 also includes an empty tray loading structure 521, an empty tray conveying mechanism 523, a re-judgment transfer belt, a re-judgment discharge port structure 531, a non-conforming transfer belt 540, and an unloading conveying mechanism 550. The empty tray loading structure 521 is used to provide empty trays, and the empty tray conveying mechanism 523 is used to transport the empty trays provided by the empty tray loading structure 521 to the unloading port structure 51. The unloading conveying mechanism 550 can grab multiple materials 2 at a time, transporting the qualified materials 2 to the unloading port structure 51, transporting the materials 2 that need to be re-judged to the re-judgment transfer belt, transporting the non-conforming materials 2 to the non-conforming transfer belt 540, and the materials 2 that need to be re-judged are transported to the re-judgment transfer belt and finally transferred to the re-judgment discharge port structure 531.

[0177] The aforementioned testing equipment 1 includes a testing section 10, a feeding section 50, and a feeding mechanism 30. The testing section 10 includes a picking mechanism 900, a conveying assembly 100, at least one flipping mechanism 200, and at least two sets of testing assemblies 300. The feeding mechanism 30 is used to convey material 2 to the testing section 10, and it includes a feeding conveyor belt, a limiting member 32, a positioning member 33, a sensing member 34, a guide member 35, and a stop member 36. The material 2 is conveyed by the feeding conveyor belt and, guided by the guide member 35, sequentially reaches the adjacent position 313 and the picking position 311. The stop member 36 can block the material 2 that has reached the picking position 311 to prevent it from continuing to be conveyed forward, so that the material 2 stops at the picking position 311 so that the picking mechanism 900 of the testing section 10 can pick it up. The limiting component 32, the stop component 36, and the guide component 35 are all made of bakelite. These components may come into direct contact with the material 2, and may even generate interaction forces. Bakelite has low hardness, which provides a certain buffering effect when colliding with the material 2, reducing the probability of damage or scratches. The limiting component 32 is located above the feeding conveyor belt 31 and at the adjacent position 313. It can restrain the material 2 in the direction of gravity, limiting its movement to prevent it from being significantly lifted by the material 2 taken by the reclaimer. Simultaneously, the limiting component 32 can adjust its position along the material 2's transmission direction to ensure it is accurately positioned at the adjacent position 313. The positioning component 33 can perform secondary positioning of the material 2 at the reclaiming position 311 in the width direction, ensuring accurate positioning for the reclaiming mechanism 900 to grasp it. The detection element can be triggered by the passing material 2, thereby recording the number of passing material 2, and thus reflecting the number of material 2 entering the picking position 311, so that the picking mechanism 900 can pick up the material after reaching the picking quantity.

[0178] The conveying assembly 100 includes at least one handling device 110 and at least two conveyor belts 130. The testing device 1 includes two cleaning mechanisms 400. The entire testing assembly 300 includes a testing assembly 300 located at a first testing station and a testing assembly 300 located at a second testing station. After the material picking mechanism 900 picks up the material, it transfers the material 2 onto the first conveyor belt 130 of the testing section 10 for transmission. During the transmission process, the material 2 is first flipped over by the flipping mechanism 200 until its back is facing up. The cleaning mechanism 400 cleans its back, and then it is tested on its back by the testing assembly 300 at the first testing station. It is then flipped again by another flipping mechanism 200. After flipping, the material 2 is facing up again and is transported by the handling device 110 to the second conveyor belt 130. During this process, the handling device 110 uses its two gripping mechanisms 115 to alternately reciprocate, achieving dual-station transport. After being transferred to the second conveyor belt 130, material 2 undergoes cleaning of its front surface by another cleaning mechanism 400. The cleaning mechanisms 400 corresponding to the first and second conveyor belts 130 move synchronously to thoroughly clean the entire surface of material 2. Subsequently, material 2 is transferred by another handling device 110 to the third conveyor belt 130, where it undergoes front-side inspection by an inspection component 300 located at the second inspection station. After inspection, material 2 is conveyed to the unloading section 50.

[0179] The unloading section 50 includes an unloading port structure 51, a re-judgment transfer belt, a re-judgment discharge port structure 531, a non-conforming transfer belt 540, an unloading and conveying mechanism 550, an empty tray loading structure 521, and an empty tray conveying mechanism 523. The unloading port structure 51 includes an empty tray positioning mechanism 511 and two outlet guide plates 513, with the empty tray positioning mechanism 511 fixed to the top of the outlet guide plates 513. The empty tray loading structure 521 provides empty trays, and the empty tray conveying mechanism 523 transports the empty trays provided by the empty tray loading structure 521 to the unloading port structure 51, where they are positioned by the empty tray positioning mechanism 511. Based on the test results, qualified material 2 is transferred to the unloading port structure 51 by the unloading and conveying mechanism 550 for unloading. Material 2 requiring re-judgment is transferred by the unloading and conveying mechanism 550 to the re-judgment transfer belt and ultimately further transferred to the re-judgment discharge port structure 531 for discharge. Non-conforming products are transferred by the unloading and handling mechanism 550 to the non-conforming transfer belt 540 for output.
