[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In view of the problems that the current belt splicing platform is easy to pinch hands during the belt splicing process, and it is difficult to provide a safety shield, which can easily cause squeezing injuries to production personnel, this embodiment provides an anti-pinching belt splicing platform, which can effectively solve the risk of pinching hands with a pressure rod during belt splicing.

[0019] Reference Figure 1 , Figure 2 The anti-pinch belt connecting platform of this embodiment includes two pressure rods 1, a platform bottom plate 2 and a driving assembly, and may also include a dust collection box 9.

[0020] The platform bottom plate 2 is arranged horizontally, and a through slot 8 is provided on the platform bottom plate 2 along its length direction. In this embodiment, the width and length of the through slot 8 are not specifically limited, and the width and length of the through slot 8 can be reasonably designed according to actual conditions. The platform bottom plate 2 can be made of lightweight materials, such as aluminum alloy carbon fiber thin plates, etc., so that the platform bottom plate 2 itself is lightweight and convenient for operators to operate.

[0021] The two pressure rods 1 are located above the platform bottom plate 2 and are respectively located on both sides of the through slot 8. The two pressure rods 1 are arranged parallel to each other and are arranged along the length direction of the platform bottom plate 2. A buffer pad 6 is provided on the side of the pressure rod 1 facing the platform bottom plate 2. A scale 7 is provided on both pressure rods 1.

[0022] The drive assembly includes two drive units, and the two drive units are respectively arranged in one-to-one correspondence with the two pressure rods 1. The drive unit includes a transmission part, a motor 3, a Honeywell sensor and a single-chip microcomputer. The transmission part includes a connecting rod 4 and a screw rod 5. The connecting rod 4 is a U-shaped structure, and its two ends slide vertically through the platform bottom plate 2 and are respectively connected to the two ends of the corresponding pressure rod 1. The screw rod 5 is vertically arranged, and one end of the screw rod 5 penetrates the connecting rod 4 and is threaded with the connecting rod 4. The output end of the motor 3 is connected to the other end of the screw rod 5. The motor 3 is connected to the single-chip microcomputer and the single-chip microcomputer controls the start and stop, forward and reverse rotation, and the forward and reverse rotation of the motor 3 drives the corresponding pressure rod 1 to rise and fall. The Honeywell sensor is connected to the motor 3 and the single-chip microcomputer. The Honeywell sensor is used to detect the rotation speed and number of revolutions of the motor 3 and feed back the detected rotation speed and number of revolutions to the single-chip microcomputer. The single-chip microcomputer controls the forward and reverse rotation of the motor 3 according to the information fed back by the Honeywell sensor.

[0023] The dust collecting box 9 is located below the platform bottom plate 2 and is used to collect dust generated when the belt is connected.

[0024] Through the above structural arrangement, when connecting the tapes, the feed electrode tape passes through between one of the pressure rods 1 and the platform bottom plate 2, and after being aligned with the scale 7 on the pressure rod 1, the motor 3 corresponding to the pressure rod 1 is started to drive the pressure rod 1 to descend and press the feed electrode tape, and then the wallpaper knife is used to cut off the excess electrode tape along the through groove 8, and the generated dust is collected by the dust collecting box 9; the discharge electrode tape passes through between the other pressure rod 1 and the platform bottom plate 2, and after being aligned with the scale 7 on the pressure rod 1, the motor 3 corresponding to the pressure rod 1 is started to drive the pressure rod 1 to descend and press the feed electrode tape, and then the wallpaper knife is used to cut off the excess electrode tape along the through groove 8, and the generated dust is collected by the dust collecting box 9; finally, the feed electrode tape and the discharge electrode tape are glued together by tape; the feed electrode tape and the discharge electrode tape can be aligned by the scale 7 on the pressure rod 1, which greatly saves time in the production process, thereby ensuring the production efficiency of battery production.

[0025] During the entire belt connection process, the Honeywell sensor detects the rotation speed and number of revolutions of the corresponding motor 3 in real time and feeds back the detected rotation speed and number of revolutions to the single-chip microcomputer; if the pressure rod 1 is descending and the operator's hand is just under the pressure rod 1, the descent of the pressure rod 1 is blocked and the speed of the motor 3 decreases. The single-chip microcomputer controls the motor 3 to rotate in the opposite direction in time according to the speed information feedback from the Honeywell sensor, thereby driving the pressure rod 1 to rise and avoiding pinching the hand.

[0026] Finally, it is noted that the control logic of the single chip microcomputer involved in this embodiment adopts mature technology in the field, which is not the inventive point of the present utility model.

[0027] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
