Description

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

[0002] With the rapid development of the 3C (computer, communication, and consumer electronics) industry, the demand for new energy lithium batteries has increased dramatically. In the manufacturing process of new energy lithium batteries, the conveying mechanism used to transport the batteries is indispensable.

[0003] However, traditional battery conveyor systems typically only transport one type of product. That is, the conveyor belt of a traditional system generally has only one type of fixture fixed to it, and each fixture can only carry one type of product. If a different product needs to be transported, the fixture on the original conveyor belt must be removed and replaced with a different type of fixture. However, this replacement process is time-consuming, labor-intensive, and requires a large number of fixtures, resulting in high costs.

[0039] This application provides a transportation device that solves the problem that traditional conveying mechanisms cannot be compatible with multiple products and cannot meet the high-efficiency production needs of the current 3C new energy lithium battery industry.

[0040] The following reference Figures 1 to 7 The present application describes a transport device according to some embodiments.

[0041] like Figure 1 , Figure 3 and Figure 4 As shown, the transport device of this application includes a conveyor belt 100 and various fixtures. The transport device has a transport direction X, and the various fixtures are all fixed on the conveyor belt 100 and are spaced apart along the transport direction X. The various fixtures are used to carry batteries of different sizes, and there are multiple of each type of fixture.

[0042] In other words, the conveyor belt 100 of the present application's transport device is fixed with a variety of different fixtures to carry batteries of different sizes, thereby achieving the purpose of transporting and handling batteries of different sizes on the same conveyor belt 100, improving overall production efficiency, and eliminating the need to disassemble and replace all individual fixtures when changing batteries of different sizes, as is the case with existing technologies. In addition, it also reduces the number of fixtures, lowers costs, and reduces maintenance time.

[0043] In the embodiments of this application, different sized batteries may refer to two different models of product batteries. In the embodiments of this application, the following description will use an example of two different models of fixtures fixed on a conveyor belt.

[0044] In the embodiments of this application, such as Figure 3 As shown, the various fixtures include a first fixture 210 and a second fixture 220. Multiple first fixtures 210 and multiple second fixtures 220 are alternately arranged along the conveying direction X. This arrangement facilitates the loading and unloading of product batteries and improves production efficiency.

[0045] As an example, such as Figure 3 and Figure 5 As shown, each fixture includes a first contoured groove fixture plate 211, a second contoured groove fixture plate 212, and a third contoured groove fixture plate 213. The first contoured groove fixture plate 211, the second contoured groove fixture plate 212, and the third contoured groove fixture plate 213 are spaced apart along the conveying direction X. Both the first contoured groove fixture plate 211 and the second contoured groove fixture plate 212 are provided with grooves, and the grooves of both plates are used to fix the same product battery.

[0046] like Figure 5 As shown, the groove can be a groove structure surrounded by multiple protrusions 2112. Specifically, the edges of the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212 are provided with multiple protrusions 2112. The multiple protrusions 2112 on the first contouring groove fixture plate 211 and the multiple protrusions 2112 on the second contouring groove fixture plate 212 are used together to clamp the same product battery. It should be noted that the overall structure of the first contouring groove fixture plate 211, the second contouring groove fixture plate 212 and the third contouring groove fixture plate 213 included in each fixture is roughly the same. The only difference is that the groove structure provided on the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212 is different (the structure of the groove is designed according to the shape of the corresponding product battery). Therefore, for ease of description, Figure 3 In the two types of fixtures, the first contour groove fixture plate 211, the second contour groove fixture plate 212, and the third contour groove fixture plate 213 use the same reference numerals.

[0047] like Figure 3 As shown, the first contoured groove fixture plate 211 and the second contoured groove fixture plate 212 of the first type of fixture 210 are used together to fix the first type of battery 310. The first contoured groove fixture plate 211 and the second contoured groove fixture plate 212 of the second type of fixture 220 are used together to fix the second type of battery 320.

[0048] In the embodiments of this application, such as Figure 5 As shown, preferably, the second contour groove fixture plate 212 is provided with two pins 2121 for positioning the product battery. Specifically, the product battery has a film (PSA film) on it, and the film has pin holes that mate with the pins 2121, serving as a reference for the battery.

[0049] The three fixture plates are made of black POM material, with S136H inlays on both sides to prevent guide contact friction and wear. In addition, the third contour groove fixture plate 213 is equipped with a sensor 214, which is used to cooperate with the detector 400 to achieve product battery positioning.

[0050] Specifically, such as Figure 1 and Figure 4 As shown, the transport device also includes a transport frame 900, a positioning mechanism 500, and a detector 400. The conveyor belt 100, positioning mechanism 500, and detector 400 are all mounted on the transport frame 900. The detector 400 detects the position of the sensor 214. When the sensor 214 on the third contour groove fixture plate 213 is detected by the detector 400, the positioning mechanism 500 is activated to position the first contour groove fixture plate 211 and the second contour groove fixture plate 212. This arrangement facilitates the loading and unloading of product batteries and improves production efficiency.

[0051] In the embodiments of this application, such as Figure 2 and Figure 4 As shown, the conveying device includes a loading position M and a unloading position N opposite to each other in the conveying direction X; there are two detectors 400, which are respectively set at the loading position M and the unloading position N; there are two positioning mechanisms 500, which are respectively set at the loading position M and the unloading position N. During the conveying process, when any sensor 214 is detected by one of the detectors 400, both positioning mechanisms 500 are activated simultaneously. Figure 4 The diagram illustrates the installation of the positioning mechanism 500 and the detector 400 at the unloading position N.

[0052] As an example, such as Figure 4As shown, the detector 400 can be two photoelectric switches arranged opposite each other in the width direction Y. When the sensing element 214 is conveyed to the loading position M or the unloading position N, the two photoelectric switches are blocked by the sensing element 214. Then, the two positioning mechanisms 500 are activated simultaneously to position the corresponding first contouring groove fixture plate 211 and second contouring groove fixture plate 212.

[0053] It should be noted that the specific positions of the two photoelectric switches located at the loading position M and the two photoelectric switches located at the unloading position N can be designed according to the actual situation. They need to meet the requirement that when the sensor 214 blocks the position, the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212 are exactly at the loading position M or the unloading position N, and that the positioning mechanism 500 is conveniently positioned.

[0054] Optionally, in embodiments of this application, the transport device may further include two additional photoelectric switches located at the loading position M and two additional photoelectric switches located at the unloading position N. During transport, both types of product batteries are transported simultaneously. After the product battery is positioned by the positioning mechanism 500, the two additional photoelectric switches located at the loading position M or the unloading position N (the two additional photoelectric switches are arranged opposite each other in the width direction Y, not shown in the figure) will determine whether there is a product battery on the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212. If so, the loading / unloading robot will perform the loading / unloading operation. Preferably, the height of the two additional photoelectric switches is the same as the height of the product battery. If there is a product battery on the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212, the additional photoelectric switches will be blocked by the product battery.

[0055] In the embodiments of this application, such as Figure 4 , Figure 5 and Figure 6 As shown, both the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212 have a notch 2111 at one end in the width direction Y. The notch 2111 is, for example, a groove, which is used for the insertion and positioning of the positioning mechanism 500.

[0056] The positioning mechanism 500 includes a cylinder 510 and two positioning rods 520. During positioning, the cylinder 510 drives the two positioning rods 520 to extend simultaneously and insert into the grooves of the first contouring groove fixture plate 211 and the second contouring groove fixture plate 212, respectively. During specific assembly, the mounting bracket 530 is fixed on the transport frame 900, and the mounting bracket 530 has two through holes for the positioning rods 520 to pass through.

[0057] In this embodiment, the transport device further includes two first guiding mechanisms. Both first guiding mechanisms are disposed on the transport frame 900, and are respectively disposed at the loading position M and the unloading position N. Figure 6As shown, the first guiding mechanism includes two sets of first guide bearings 610, which are arranged opposite to each other in the width direction Y. Both sets of first guide bearings 610 are located above the conveyor belt 100. When the fixture is conveyed to the loading position M or the unloading position N, both sets of first guide bearings 610 are in contact with the top of the fixture.

[0058] During assembly, bracket 540 is fixed on mounting bracket 530, and first guide bearing 610 is fixed on bracket 540. During the conveying process, first guide bearing 610 can play a guiding and stabilizing role. After positioning mechanism 500 is positioned, first guide bearing 610 can work with positioning mechanism 500 to achieve stable positioning (vertical positioning) of fixture.

[0059] In this embodiment, the specific positions of the bracket 540 and the mounting bracket 530 can be adjusted according to actual needs (and thus the positions of the cylinder 510 and the first guide bearing 610 can be adjusted). For example, each group of first guide bearings 610 includes two first guide bearings 610. When the fixture is positioned by the positioning mechanism 500, the four first guide bearings 610 are in contact with the first contour groove fixture plate 211 and the second contour groove fixture plate 212, respectively.

[0060] Furthermore, in an embodiment of this application, the transport device further includes two second guiding mechanisms. Both second guiding mechanisms are disposed on the transport frame 900, and are respectively disposed at the loading position M and the unloading position N. Figure 6 As shown, the second guiding mechanism includes two sets of second guide bearings 620, which are arranged opposite to each other in the width direction Y. When the fixture is conveyed to the loading position M or the unloading position N, the two sets of second guide bearings 620 respectively contact the two end faces of the fixture in the width direction Y.

[0061] During assembly, the second guide bearing 620 is fixed on the mounting bracket 530. During the conveying process, the second guide bearing 620 can play a guiding and stabilizing role. After the positioning mechanism 500 is positioned, the second guide bearing 620 can work with the positioning mechanism 500 to achieve stable positioning (left and right positioning) of the fixture.

[0062] In this embodiment, the specific positions of the bracket 540 and the mounting bracket 530 can be adjusted according to actual needs (and thus adjust the positions of the cylinder 510, the first guide bearing 610, and the second guide bearing 620). For example, each group of second guide bearings 620 includes two second guide bearings 620. When the fixture is positioned by the positioning mechanism 500, the four second guide bearings 620 are in contact with the first contour groove fixture plate 211 and the second contour groove fixture plate 212, respectively.

[0063] In embodiments of this application, the transport device further includes a drive shaft 710 and a driven shaft (not shown in the figure). Figure 7 As shown, the drive shaft 710 has two drive synchronous pulleys 720 connected to both ends, and a bushing 730 is fitted in the middle of the drive shaft 710. The driven shaft has two driven synchronous pulleys connected to both ends. The conveyor belt 100 includes two synchronous toothed belts 110. One synchronous toothed belt 110 is connected to one drive synchronous pulley 720 and one driven synchronous pulley; the other synchronous toothed belt 110 is connected to another drive synchronous pulley 720 and another driven synchronous pulley. This arrangement increases the overall rigidity of the device with the two synchronous toothed belts 110, preventing excessive shaking of the fixture during transportation.

[0064] In the embodiments of this application, such as Figure 1 and Figure 7 As shown, the transport device also includes a fixing mechanism 800 for fixing the drive shaft 710 or the driven shaft.

[0065] The fixing mechanism 800 includes a bearing housing 810, a bearing 820, and two upright plates 830. Among them, for example... Figure 7 As shown, for the fixing mechanism 800 at one end where the drive shaft 710 is located, a bearing seat 810 is provided on the outer side of one of the two vertical plates 830. The bearing seat 810 is connected to one end of the shaft body through a bearing 820. When the synchronous toothed belt 110 needs to be replaced, the bearing seat 810 is removed first, then the drive shaft 710 can be pulled out from right to left, and then the two drive synchronous pulleys 720 can be disassembled, realizing the quick replacement of the synchronous toothed belt 110.

[0066] For the fixing mechanism 800 at the end where the driven shaft is located, bearing seats 810 are provided on the outer sides of the two vertical plates 830. The two bearing seats 810 are connected to the two ends of the driven shaft through bearings 820. When the synchronous toothed belt 110 needs to be replaced, the bearing seats 810 are removed first, then the driven shaft is pulled out, and then the two driven synchronous pulleys can be disassembled, realizing the quick replacement of the synchronous toothed belt 110.

[0067] Furthermore, in the embodiments of this application, such as Figure 7As shown, the transport device also includes a motor 840 and a drive wheel and a driven wheel connected by a transmission (the drive wheel and driven wheel are located inside the housing 850). For the fixing mechanism 800 at the end where the drive shaft 710 is located, a bearing seat 810 is provided on the outer side of one of the two upright plates 830, and a drive wheel and a driven wheel are provided on the outer side of the other upright plate 830. The motor 840 is located between the two upright plates 830, coaxially connected to the drive wheel, and coaxially connected to the drive shaft 710. This arrangement, by adding a drive wheel and a driven wheel connected by a transmission between the motor 840 and the drive shaft 710, allows the motor 840 to be installed between the two upright plates 830, thereby reducing the space occupied by the device.

[0068] Furthermore, in the embodiments of this application, such as Figure 7 As shown, motor 840 can be a servo motor, and a reducer 860 can also be connected to the output end of the servo motor. The synchronous toothed belt 110 is relatively long and has a large load, and the reducer 860 can increase the output torque of the servo motor.

[0069] In summary, the conveyor belt 100 of the present application's transportation device is fixed with two different fixtures to carry two different product batteries, thereby achieving the purpose of transporting and handling different product batteries on the same conveyor belt 100, improving overall production efficiency, and eliminating the need for disassembling and replacing all individual fixtures when changing batteries of different sizes, as is required in the prior art. Furthermore, it reduces the number of fixtures, lowers costs, and reduces maintenance time.

[0070] Based on this, the conveying device of this application can guide and quickly position the loading and unloading fixtures. It has two different fixtures installed at intervals, which can simultaneously accommodate two different product batteries without the need for model change. The drive shaft 710 and driven shaft of the conveying device of this application can be pulled out from one side to quickly replace the synchronous toothed belt, thereby improving production efficiency and positioning accuracy.

[0071] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them.
