[0044] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present utility model can be combined with each other without conflicting with each other.

[0045] Refer to Figure 1 、 2, a pulling belt mechanism for transporting NG batteries, comprising: a frame 1 and a conveying assembly 2 provided on the frame 1; the conveying assembly 2 includes a driving device 21 and a conveyor belt 22, and the driving device 21 is used to drive the conveyor belt 22 to displace from the first end of the frame 1 to the second end; a plurality of fixing seats 23 are provided on the conveyor belt 22 for placing and fixing the batteries; an induction assembly 3 is provided on the frame 1 on the side facing the first end for detecting whether a battery is placed on the fixing seat 23 at the first end; after the induction assembly 3 detects that there is a battery on the fixing seat 23 at the first end, the driving device 21 can drive the fixing seat 23 to move along the second end. After finding an NG battery, the manipulator takes out the NG battery and places it on the fixing seat 23 at the first end. When the induction assembly 3 detects that a battery has been placed at this position, the driving device 21 will drive the conveyor belt 22 to rotate and convey the fixing seat 23 at the first end to the second end, so that the first end of the frame 1 is always in a state where an NG battery can be placed. The fixing seat 23 can fixedly place the battery, and the state of the battery is stable after being placed on the fixing seat 23, thus solving the problem that in the prior art, the slender short-knife battery is not stably placed at the NG position and is prone to risks such as battery skew and tipping. By setting a larger number of fixing seats 23, the number of NG batteries that can be placed can be increased, and the placed NG batteries have good stability and will not be skewed or tipped. The pulling belt mechanism for NG batteries of the present utility model can be set on each liquid injection machine, and can efficiently and conveniently remove NG batteries, enabling the entire production line to operate efficiently without jamming.

[0046] Refer to Figure 1 , protective covers 12 are respectively provided at the first end and the second end of the frame 1 for protecting the conveying assembly 2.

[0047] Among them, the induction assembly 3 includes a first induction bracket 31 and a second induction bracket 33 provided on the frame 1. A sensing transmitter 32 is provided on the first induction bracket 31, and a sensing receiver 34 is provided on the second induction bracket 33; when there is a battery on the fixing seat 23 at the first end of the frame 1, the battery will block the signal emitted by the sensing transmitter 32, so that the sensing receiver 34 cannot receive the signal. Specifically, a height difference is formed between the first induction bracket 31 and the second induction bracket 33 for detecting whether a battery is placed on the corresponding fixing seat 23. That is, a set of sensing transmitter 32 and sensing receiver 34 detects one fixing seat 23, thereby improving the detection accuracy. After determining that the fixing seat 23 is placed with a battery, the driving device 21 moves the fixing seat 23 so that the next empty fixing seat 23 is located at the first end, facilitating the subsequent manipulator to put the NG battery into the fixing seat 23.

[0048] Refer to Figure 1 、 2, when the fixing base 23 has multiple fixing positions, that is, the fixing base 23 located at the first end has multiple fixing positions, and any fixing position is detected by a set of sensing transmitters 32 and sensing receivers 34. Only when all the fixing positions on the fixing base 23 at the first end are placed with batteries, the driving device 21 drives the conveyor belt 22 to move, so that the fixing base 23 at the first end moves towards the second end, so that the fixing base 23 with a vacant position moves to the first end for standby. For example, as Figure 7 , the fixing base 23 has 4 fixing positions, corresponding to 4 conveyor belts 22. In addition, on the first belt body 221, 4 or 5 fixing bases 23 are provided, so that the number of fixing positions for placing NG batteries on the entire first belt body 221 will reach 16 or 20, greatly reducing the time of manual intervention.

[0049] In addition, a positioning sensor 4 is provided at the first end and / or the second end of the frame 1 for detecting whether the fixing base 23 loaded with a battery has moved into place. The positioning sensor 4 can be set at the first end, the second end, and can be set at the first end and the second end at the same time. It is mainly used to detect the displacement of the fixing base 23 to determine whether the fixing base 23 with an NG battery or the vacant fixing base 23 has moved into place.

[0050] In some embodiments, referring to Figure 7 , the fixing base 23 includes a first fixing cavity 231 and a second fixing cavity 232 which are oppositely arranged, and both ends of the battery are respectively embedded in the first fixing cavity 231 and the second fixing cavity 232. The first fixing cavity 231 and the second fixing cavity 232 have the same structure, and the battery can be embedded in the first fixing cavity 231 and the second fixing cavity 232 at the same time. Specifically, the first fixing cavity 231 has a first bottom plate and three side plates located on the first bottom plate. The three side plates and the bottom plate form the first fixing cavity 231 facing the second fixing cavity 232; the second fixing cavity 232 has a second bottom plate and three side plates located on the second bottom plate. The three side plates and the bottom plate form the second fixing cavity 232 facing the first fixing cavity 231. It can be understood that when the battery is placed, the first bottom plate and the second bottom plate support the bottoms of the two side segments of the battery, and the oppositely arranged side plates are used to support the sides of the battery, so that the battery placed on the fixing base 23 will not fall or tilt.

[0051] In some embodiments, referring to Figure 1, the fixing base 23 further includes a fixing plate 233. One side of the fixing plate 233 is fixedly connected to the conveyor belt 22, and the other side is fixedly connected to the first fixing cavity 231 or the second fixing cavity 232. On both sides of the fixing plate 233, support ends 2331 protrude along the displacement direction perpendicular to the conveyor belt 22. On the frame 1, there is a support frame 11 for supporting the support ends 2331. When the fixing base 23 moves horizontally, the support frame 11 can always support the support ends 2331. It can be understood that, referring to Figure 7 , fixing plates 233 are provided below both the first fixing cavity 231 and the second fixing cavity 232, that is to say, both the first fixing cavity 231 and the second fixing cavity 232 are connected to the conveyor belt 22 through the fixing plates 233. During use, driven by the driving device 21, the transfer belt will drive the fixing base 23 to perform a periodic cycle. A single first fixing cavity 231 or second fixing cavity 232 can correspondingly pass through the driving wheel 2123 and the driven wheel 2133 of the driving device 21 along with the conveyor belt 22. In addition, after multiple batteries are placed on the fixing base 23, the multiple batteries greatly increase the pressure on the conveyor belt, affecting the load-bearing capacity of the conveyor belt 22 and the stability of the conveyor belt 22 during the periodic cycle. Therefore, the support frames 11 provided on both sides of the conveyor belt 22 can be used to support the support ends 2331 located on both sides of the fixing base 23, thus greatly improving the load-bearing capacity and running stability of the conveyor belt 22.

[0052] Furthermore, referring to Figures 1-3 , the conveyor belt 22 includes a first belt body 221 located at the upper part and a second belt body 222 located at the lower part. The support frame 11 includes a first support plate 111 located at the upper end and a second support plate 112 located at the lower end; the first support plate 111 is located below the first belt body 221 and corresponds to the position where the battery is carried on the first belt body; the second support plate 112 is located below the support ends 2331 on both sides of the second belt body 222. It can be understood that when the fixing base 23 rotates in a cycle through the conveyor belt 22, the first belt body 221 is supported by the first support plate 111. Among them, the first support plate 111 supports the bottom of the first belt body 221 and is located below the fixing base 23. That is to say, the first support plate 111 is arranged corresponding to the position of the battery on the first belt body 221, so that the fixing base 23 can always be supported. Even when batteries are placed on the fixing base 23, it can be stably conveyed on the conveyor belt 22. In addition, the second belt body 222 is supported by the second support plate 112. Since the fixing base 23 on the second belt body 222 has unloaded the battery at this time, the load on the second belt body 222 is relatively light at this time. Therefore, the second support plate 112 can achieve a good support effect by setting the support ends on both sides of the second belt body 222.

[0053] In some embodiments, there are multiple conveyor belts 22, and the fixed plates 233 are respectively fixedly connected to the multiple conveyor belts 22. The fixed seat 23 has a plurality of first fixed cavities 231 and second fixed cavities 232 along the extending direction of the fixed plate 233. It can be understood that the length of the fixed seat 23 is extended along the direction perpendicular to the transmission direction of the conveyor belt 22, and more conveyor belts 22 are arranged below the fixed seat 23 for support. Thus, the number of fixed seats 23 can be increased, and more NG batteries can be carried simultaneously.

[0054] In some embodiments, referring to Figures 4-6 , the driving device 21 includes a motor 211, a driving part 212, and a driven part 213; the driving part 212 and the driven part 213 are respectively located at the first end and the second end of the frame 1, and the driving part 212 and the driven part 213 are respectively in transmission connection with the conveyor belt 22. It can be understood that the conveyor belt 22 is sleeved on the driving part 212 and the driven part 213, and the driving part 212 outputs rotational power to drive the conveyor belt 22 to rotate.

[0055] Further, referring to Figure 4 , 5 , the driving part 212 includes: first fixed lock sleeves 2121 located on both sides of the frame 1, a transmission shaft 2122 fixed by the first fixed lock sleeves 2121 and rotatably connected to the first fixed lock sleeves 2121, a driving wheel 2123 fixedly connected to the transmission shaft 2122, and the transmission shaft 2122 is in transmission connection with the motor 211; referring to Figure 6 , the driven part 213 includes: second fixed lock sleeves 2131 located on both sides of the frame 1, a driven shaft 2132 fixed by the second fixed lock sleeves 2131 and clamped with the second fixed lock sleeves 2131, and a driven wheel 2133 rotatably connected to the driven shaft 2132. The transmission shaft 2122 is in transmission connection with the motor 211, that is, the motor 211 drives the rotating shaft to rotate, and the transmission shaft 2122 then drives the driving wheel 2123 to rotate, thereby outputting transmission power. It should be noted that the driven wheel 2133 is rotatably connected to the driven shaft 2132. Preferably, a rotating bearing is arranged between the driven shaft 2132 and the driven wheel 2133. In addition, the number of driving wheels 2123 and driven wheels 2133 is in a corresponding relationship. When multiple conveyor belts 22 are provided, the corresponding number of driven wheels 2133 and driving wheels 2123 can be arranged on the transmission shaft 2122 and the driven shaft 2132.

[0056] Further, a transmission 214 is arranged between the motor 211 and the transmission shaft 2122, and the transmission 214 can adjust the speed of the output of the motor 211. It can be understood that when there are more NG batteries, the pulling mechanism needs to increase the output speed of the motor 211 to improve the conveying efficiency.
