[0002] In an era of rapid development of new energy, cylindrical lithium-ion batteries have become the main choice for many industries such as the automotive industry and power tools. During the product manufacturing process, many of the machine mechanisms in the assembly workshop are translational equipment (including necking machines, groove rolling inspection machines, laser welding machines, etc.). This type of equipment has a common feature: the overall process of the equipment is arranged in a linear manner, relying on frequency conveyor belts to transfer, and through different mechanisms, to manufacture the required products.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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. Example

[0021] See also Figure 1-Figure 3 A conveying device for detecting dropped or missing batteries includes a conveying mechanism 1. The conveying mechanism 1 is a translational conveying device used in battery production mechanisms such as necking machines, groove rolling detection machines, and laser welding machines. A number of battery placement positions are evenly arranged along the conveying direction on the conveying mechanism 1. The conveying mechanism 1 drives each battery placement position to pass through the loading area 2, the defective product discharge area 3, and the unloading area 4 in sequence. When the conveying mechanism 1 drives the battery placement position through the loading area 2, the loading mechanism provided at the loading area 2 loads the batteries onto each battery placement position of the conveying mechanism 1. When the conveying mechanism 1 drives the battery placement position through the defective product discharge area 3, the discharge mechanism provided at the defective product discharge area 3 removes the defective batteries on the conveying mechanism 1. When the conveying mechanism 1 drives the battery placement position through the unloading area 4, the unloading mechanism provided at the unloading area 4 removes the batteries from each battery placement position on the conveying mechanism 1. The loading mechanism, unloading mechanism, and discharge mechanism are all robots or other forms of existing technology products. This structure is not described in detail in this utility model.

[0022] A loading detection mechanism is also provided in the loading area 2. The loading detection mechanism detects the loading status of each battery placement position in turn. Specifically, in the conveying direction of the conveying mechanism 1, the loading detection mechanism is located behind the loading mechanism. The loading detection mechanism is a visual detection system or a sensor detection system. The loading detection mechanism detects whether each battery placement position is loaded in turn, and records and saves the detection results.

[0023] The defective product discharge area 3 is equipped with a discharge detection mechanism that sequentially detects the defective product discharge status of each battery placement position. Specifically, the discharge detection mechanism is located behind the discharge mechanism in the conveying direction of the conveying mechanism 1. The discharge detection mechanism sequentially detects whether there are batteries in each battery placement position and records and stores the detection results. The discharge detection mechanism determines whether the battery in the battery placement position has been rejected by the discharge mechanism by detecting whether there are batteries in the battery placement position. Similar to the feeding detection mechanism, the discharge detection mechanism also uses a visual detection system or a sensor detection system.

[0024] A blanking detection mechanism is provided in the blanking area 4. The blanking detection mechanism sequentially detects the blanking status of each battery placement position and compares the detection results with the detection results of the loading detection mechanism and the discharge detection mechanism. Specifically, in the conveying direction of the conveying mechanism 1, the blanking detection mechanism is provided in front of the blanking mechanism, or the conveying mechanism 1 is provided in the blanking channel of the blanking mechanism. The blanking detection mechanism sequentially detects whether there are batteries in each battery placement position. The blanking detection mechanism compares the detection results with the results of the loading detection mechanism and the discharge detection mechanism to determine whether any batteries have fallen. The blanking detection mechanism can be a visual detection system or a sensor detection system.

[0025] The loading detection mechanism detects the number and position of products fed into the conveying mechanism 1, the discharging detection mechanism detects the number and position of products rejected from the conveying mechanism 1, and the unloading detection mechanism detects the number and position of products output from the conveying mechanism 1. By comparing the number of output products with the number of input products and the number of rejected products, it can be understood whether there are batteries dropped or missing during the processing process. When a battery is dropped or missing, the battery placement position of the dropped battery can be quickly locked through the detection results of the loading detection mechanism, the discharging detection mechanism and the unloading detection mechanism, so as to facilitate targeted processing.

[0026] As a specific example of a blanking detection mechanism, see Figure 2 and Figure 3 The blanking detection mechanism includes a sensor 5 and an installation and adjustment mechanism 6. The installation and adjustment mechanism 6 is installed on the frame of the conveying mechanism 1. The sensor 5 is set on the installation and adjustment mechanism 6 and its position is adjusted by the installation and adjustment mechanism 6.

[0027] The installation and adjustment mechanism 6 includes a support seat 61, a transverse connecting plate 62, a vertical connecting plate 63, an inductor support seat 64, and an inductor bracket 65. The support seat 61 is connected to the frame of the conveying mechanism 1 by means of bolts, screws, anchors, and other structures. A first transverse waist hole and a second transverse waist hole are provided on the transverse connecting plate 62. The length direction of the first transverse waist hole is perpendicular to the length direction of the second transverse waist hole. The transverse connecting plate 62 is provided on the support seat 61 and is movable and adjustable relative to the support seat 61 along the first transverse waist hole. Specifically, a first connecting hole is provided on the support seat 61. The first connecting hole is threadedly engaged with a first connecting bolt provided through the first transverse waist hole, thereby installing the transverse connecting plate 62 on the support seat 61. By rotating the first connecting bolt and pressing the transverse connecting plate 62 onto the support seat 61, the position of the transverse connecting plate 62 can be fixed. By loosening the first connecting bolt, the position of the transverse connecting plate 62 can be adjusted along the length direction of the first transverse waist hole. In order to prevent the transverse connecting plate 62 from rotating relative to the support seat 61 and to prevent the transverse connecting plate 62 from shifting relative to the support seat, there are preferably two or more first transverse waist holes, and at least two first connecting holes are provided on the support seat 61 corresponding to each first transverse waist hole.

[0028] The vertical connecting plate 63 is mounted perpendicular to the transverse connecting plate 62 and is movable relative to the transverse connecting plate 62 along the second transverse waist hole. Specifically, a second connecting hole is provided at the bottom end of the vertical connecting plate 63. The second connecting hole is threadedly engaged with a second connecting bolt inserted through the second transverse waist hole. Tightening the second connecting bolt causes the transverse connecting plate 62 to be tightly attached to the vertical connecting plate 63, thereby attaching the vertical connecting plate 63 to the transverse connecting plate 62. After loosening the second connecting bolt, the position of the vertical connecting plate 63 can be adjusted along the length of the second transverse waist hole. There are two or more second connecting holes, and at least two of the second connecting holes are connected to the second connecting bolt to prevent the vertical connecting plate 63 from rotating relative to the transverse connecting plate 62.

[0029] In some embodiments, the upper surface of the transverse connecting plate 62 is provided with a guide groove, the length direction of the guide groove being parallel to the length direction of the second transverse waist hole, the second transverse waist hole being disposed within the guide groove, the bottom end of the vertical connecting plate 63 being disposed within the guide groove and being movable and adjustable along the guide groove, and the vertical connecting plate 63 being further embedded in the guide groove to enhance the connection and stability between the vertical connecting plate 63 and the transverse connecting plate 62. In a further embodiment, the lower surface of the transverse connecting plate 62 is provided with a bolt receiving groove, the guide groove being in communication with the bolt receiving groove, and after the vertical connecting plate 63 and the transverse connecting plate 62 are connected using a second connecting bolt, the bolt head of the second connecting bolt is disposed within the bolt receiving groove, thereby preventing interference with the movement and adjustment of the transverse connecting plate 62 relative to the support base.

[0030] A vertical waist hole is provided on the vertical connecting plate 63, and the sensor support seat 64 is provided on the vertical connecting plate 63 and can be moved and adjusted relative to the vertical connecting plate 63 along the vertical waist hole. Specifically, a third connecting hole is provided on the side of the sensor support seat 64. The third connecting hole is threadedly engaged with a third connecting bolt provided through the vertical waist hole, so that the sensor support seat 64 is connected to the vertical connecting plate 63. Tightening the third connecting bolt causes the vertical connecting plate 63 to be tightly attached to the sensor support seat 64, thereby installing the sensor support seat 64 on the vertical connecting plate 63. After loosening the third connecting bolt, the height position of the sensor support seat 64 can be adjusted along the vertical waist hole. As a preferred embodiment, in order to improve the installation stability of the sensor support seat 64 and prevent the sensor support seat 64 from rotating relative to the vertical connecting plate 63, at least two vertical waist holes are provided on the vertical connecting plate 63. A third connecting hole is provided on the sensor support seat 64 corresponding to each vertical waist hole, and at least two third connecting holes are provided with a third connecting bolt.

[0031] The sensor bracket 65 is provided with a third transverse waist hole. The sensor bracket 65 is mounted on the sensor support base 64 and can be moved and adjusted relative to the sensor support base 64 along the third transverse waist hole. Specifically, the sensor support base 64 is provided with a fourth connecting hole. The fourth connecting hole is threadedly engaged with a fourth connecting bolt inserted through the third transverse waist hole. The fourth connecting bolt is rotated to tightly fit the sensor support base 64 and the sensor bracket 65, thereby installing the sensor bracket 65 on the sensor support base 64. After loosening the fourth connecting bolt, the position of the sensor bracket 65 can be adjusted along the third transverse waist hole. As a preferred embodiment, the sensor support base 64 is provided with at least two fourth connecting holes corresponding to each sensor bracket 65. The distribution direction of the fourth connecting holes is perpendicular to the length direction of the third transverse waist hole. The position of the sensor bracket 65 can be adjusted by engaging different fourth connecting holes. The sensor bracket 65 is provided with a sensor 5, which can be a proximity switch, a photoelectric switch, etc. The conveying mechanism 1 drives each battery placement position to pass through the sensing range of the sensor in sequence.

[0032] As a preferred embodiment, at least two third transverse waist holes are provided on the sensor support seat 64, and the length direction and distribution direction of the third transverse waist holes are parallel to the conveying direction of the conveying mechanism 1. A sensor bracket 65 is provided at each third transverse waist hole, and a sensor 5 is provided on each sensor bracket 65. The spacing between adjacent sensors is the same as the spacing between adjacent battery placement positions. Multiple sensors 5 are detected simultaneously to improve the detection efficiency.

[0033] The position of the sensor can be adjusted in multiple directions by using the installation adjustment mechanism 6 so that the sensor is adapted to the battery placement position on the conveying mechanism 1. Of course, when the loading detection mechanism and the unloading detection mechanism adopt a sensor detection system, the sensors of each detection system can also be installed and adjusted by using the installation adjustment mechanism 6.

[0034] The conveying device of the present invention can also be used in conjunction with an alarm. The unloading detection mechanism is connected to the alarm system of the alarm. When a battery is detected to be dropped or missing, the alarm sounds an alarm, prompting the staff to stop the machine and handle the problem, thereby avoiding damage to the equipment. By using a conveying device that detects battery drops or missing, the utility model can promptly detect battery drops during the production process, effectively reducing the number of scrapped products. In addition, by promptly detecting battery drops, equipment abnormalities can be promptly detected and corresponding adjustments can be made in a timely manner to avoid equipment damage.
