[0046] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0047] Figure 1 It is a structural schematic diagram of a film strip transporting device provided in an embodiment of the present application. The film strip transporting device provided in the present application may include at least two groups of film strip transporting parts arranged opposite to each other, and the two groups of film strip transporting parts respectively clamp the two ends of n film strips. For each group of film strip transporting parts, the film strip transporting parts include n groups of chucks 10, lower chuck mounting rails 20 and driving mechanisms.

[0048] Generally speaking, the two groups of film strip transport parts have the same structure, and each group of film strip transport parts is provided with n groups of clamps 10. The clamps 10 on the two groups of film strip transport parts correspond to each other and cooperate to clamp the two ends of the same film strip. In other words, the i-th clamp 10 on the first group of film strip transport parts cooperates with the i-th clamp 10 on the second group of film strip transport parts to clamp the two ends of the i-th film strip respectively.

[0049] Each group of chucks 10 includes an upper chuck 11 and a lower chuck 12 which are opposite to each other and are used to clamp the film strip. The lower chuck 12 of each group of chucks 10 is installed on a lower chuck mounting track 20. The driving mechanism is transmission-connected to the n chucks 10, and the driving mechanism drives the n groups of chucks 10 to move along the lower chuck mounting track 20.

[0050] In actual application scenarios, the spacing between the n film strips at the film strip feeding station is small, while the spacing between the film strips required at the film insertion station is large. Therefore, when n groups of chucks 10 pick up n film strips, it is usually necessary to adjust the spacing between the n film strips to ensure that the spacing between the film strips meets the film insertion spacing requirements. And the spacing adjustment between the n groups of chucks 10 also needs to meet the picking spacing requirements for the n film strips at the film strip feeding station. Therefore, the driving mechanism in the present application can drive the n groups of chucks 10 to move along the lower chuck mounting track 20, and can adjust the spacing between the n groups of chucks 10.

[0051] In order to adjust the spacing between n groups of chucks 10, in a possible implementation of the present application, the second to nth lower chucks 12 are movably mounted on the lower chuck mounting track 20, and each group of chucks 10 is connected to each other via a flexible member.

[0052] The first group of chucks 10 are fixedly installed, that is, the upper chuck 11 and the lower chuck 12 of the first group of chucks 10 are fixedly installed, and the nth group of chucks 10 are transmission connected to the driving mechanism through a connecting piece. When the driving mechanism drives the nth group of chucks 10 to move along the lower chuck installation track 20, the flexible parts drive each group of chucks 10 to move closer to and away from each other to adjust the spacing between the n film strips clamped.

[0053] In order to achieve the clamping and opening between the upper clamp 11 and the lower clamp 12, the present application provides at least two installation methods of the clamp 10, which can be seen in Figure 2 and Figure 3 shown.

[0054] Figure 2 This is a partial schematic diagram of the installation of the clamp in the film strip handling device provided in one embodiment of the present application, combined with Figure 1 and Figure 2 The film strip transporting part provided in the present application may further include an upper chuck mounting rail 40, the tail portion of each upper chuck 11 is mounted on the upper chuck mounting rail 40, and the middle portion of each group of upper chucks 11 and lower chucks 12 is connected by a pin shaft. The film strip transporting part may further include a first clamping action part 50 installed at both ends of the upper chuck mounting rail 40, and the two first clamping action parts 50 act synchronously to jointly drive the upper chuck mounting rail 40 to rise or fall. When the upper chuck mounting rail 40 rises, it drives the tail ends of each upper chuck 11 to rise, and the clamping part of each upper chuck 11 rotates around the corresponding rotation axis to press against the clamping part of the corresponding lower chuck 12.

[0055] Still see Figure 2 In order to realize the clamping action between the upper clamp 11 and the lower clamp 12, the first clamping action part 50 may include a connecting plate 51, a sliding device 52 and a lifting cylinder 53, wherein:

[0056] The connecting plate 51 is installed on the sliding device 52. The sliding device 52 here may include a slider, a sliding drive, a slide rail, etc. The connecting plate 51 is installed on the slide rail through the slider, and the sliding drive drives the connecting plate 51 to move along the slide rail.

[0057] The end of the upper chuck mounting rail 40 passes through the connecting plate 51 and is connected to the driving end of the lifting cylinder 53.

[0058] The lifting cylinder 53 drives the upper chuck mounting rail 40 to rise along the sliding device 52, so as to drive the mounting parts of the respective upper chucks 11 on the upper chuck mounting rail 40 to rise, and further drive the clamping parts of the upper chucks 11 to move around the rotation axis towards the clamping parts of the corresponding lower chucks 12, realizing the clamping of the chucks.

[0059] The lifting cylinder 53 drives the upper chuck mounting rail 40 to descend along the sliding device 52, so as to drive the mounting parts of the respective upper chucks 11 on the upper chuck mounting rail 40 to descend, and further drive the clamping parts of the upper chucks 11 to move around the rotation axis away from the clamping parts of the corresponding lower chucks 12, realizing the opening of the chuck 10.

[0060] Figure 3 It is a schematic structural diagram of the film strip handling device provided in another embodiment of the present application. In Figure 3 the illustrated embodiment, the tails of the upper chucks 11 and the tails of the lower chucks 12 of each group of chucks 10 provided in the present application are connected by springs, the middle parts of the upper chucks 11 and the lower chucks 12 of each group of chucks 10 are installed by pins, and the film strip handling part further includes a second clamping action part 60. The second clamping action part 60 includes a pressure rod 61 and a pressure rod driving mechanism 62, wherein:

[0061] The driving end of the pressure rod driving mechanism 62 is connected to the pressure rod 61, and the pressure rod 61 is arranged above the tails of the respective upper chucks 11.

[0062] The pressure rod driving mechanism 62 drives the pressure rod 61 downward, and the pressure rod 61 presses the tails of the respective upper chucks 11 towards the tails of the corresponding lower chucks 12, realizing the opening of the chuck 10.

[0063] The pressure rod driving mechanism 62 drives the pressure rod 61 upward, the pressure rod 61 moves away from the tails of the respective upper chucks 11, and the tails of the respective upper chucks 11 are separated from the tails of the corresponding lower chucks 12 under the action of the corresponding springs, realizing the clamping of the chuck 10.

[0064] Still referring to Figure 1 as shown, in order to drive n groups of chucks 10, the driving mechanism provided in the present application may include a driving motor 31, a driving wheel 32, a driven wheel 33 and a conveyor belt 34.

[0065] The driving wheel 32 and the driven wheel 33 are respectively installed at both ends of the installation and clamping where the lower chuck installation track 20 is located. The conveyor belt is sleeved on the driving wheel 32 and the driven wheel 33. The nth group of chucks 10 is fixed to the conveyor belt 34 through a connecting piece. The driving end of the driving motor 31 is in transmission connection with the driving wheel 32.

[0066] When the driving motor 31 rotates forward, it drives the nth group of chucks 10 to move along the lower chuck installation track 20 in the direction close to the 1st group of chucks 10 through the driving wheel 32 and the conveyor belt 34. When the driving motor 31 rotates reversely, it drives the nth group of chucks 10 to move along the lower chuck installation track 20 in the direction away from the 1st group of chucks 10 through the driving wheel 32 and the conveyor belt 34. The rotation angle and the number of rotation turns of the driving motor 31 determine the distance between the n groups of chucks 10.

[0067] In a possible implementation manner, when ensuring that the chuck 10 can move smoothly on the lower chuck installation track 20, in order to further ensure that adjacent chucks 10 can approach each other to clamp the film strip with a smaller clamping distance, the lower chuck installation track 20 provided in this application may further include four guide rails arranged in a matrix. One of the adjacent two lower chucks 12 is sleeved on the first group of diagonally opposite guide rails through a sleeve, and the other of the adjacent two lower chucks 12 is sleeved on the second group of diagonally opposite guide rails through a sleeve.

[0068] The film strip handling device may further include a mounting plate 70. Two groups of film strip handling parts are fixed to the mounting plate 70. The lower end of the mounting plate 70 is slidably mounted on the slide rail of the machine table through a slider.

[0069] The film strip handling device may further include two jacking mechanisms 80. The two jacking mechanisms 80 are respectively installed at the lower ends of the two groups of film strip handling parts, and the two jacking mechanisms 80 respectively drive the two groups of film strip handling parts to lift.

[0070] In a possible implementation manner, the film strip handling device provided in this application can also stretch the film strip clamped and handled, as Figure 4 shown, which is a top view of the film strip handling device provided in another embodiment of this application. The film strip handling device provided in this application may further include a film strip stretching motor 91, a telescopic block 92, a first connecting rod 93 and a second connecting rod 94.

[0071] The telescopic block 92 is located between the two groups of film strip handling parts. The first connecting rod 93 and the second connecting rod 94 are respectively connected between the telescopic block 92 and the two groups of film strip handling parts, that is, the first connecting rod 93 is connected between the telescopic block 92 and the first group of film strip handling parts, and the second connecting rod 94 is connected between the telescopic block 92 and the second group of film strip handling parts.

[0072] The driving end of the film strip stretching motor 91 is connected to the telescopic block 92. The telescopic block 92 is usually installed on a slide rail located in front of the two groups of film strip handling parts and in the same extension direction as the two groups of film strip handling parts. The film strip stretching motor 91 drives the telescopic block 92 to move along the slide rail. Correspondingly, the first connecting rod 93 and the second connecting rod 94 drive the two groups of film strip handling parts to approach and move away from each other under the drive of the telescopic block 92. When the two groups of film strip handling parts move away from each other, the stretching between the film strips clamped by the two groups of film strip handling parts is realized.

[0073] In summary, the film strip handling device provided by the present application, by setting two groups of film strip handling parts, uses multiple chucks on the film strip handling parts to simultaneously clamp the two ends of n film strips, realizes the clamping of multiple film strips, and by setting the movement of multiple chucks, realizes the movement of the clamped n film strips, which is applicable to the application scenario requirements during film strip feeding and film strip inserting. The picking and moving of the film strips are relatively simple, improving the efficiency of film strip inserting.

[0074] The present application also provides a film strip inserting device. The film strip inserting device includes a film cutting and stretching device, a film strip handling device, and a jacking device. The film cutting and stretching device can be referred to the description in Figures 1 to 3 and will not be elaborated here.

[0075] The film cutting and stretching device provided by the present application outputs n film strips. Generally, since the film cutting and stretching device simultaneously cuts a film tape to obtain n film strips, the distance between the n film strips output by the film cutting and stretching device is relatively small.

[0076] The film strip handling device respectively clamps the two ends of n film strips through n groups of chucks of the two groups of film strip handling parts, separates the clamped film strips by a predetermined interval, and transports them to the film strip inserting station. When the film strip handling device moves to the film cutting and stretching device to clamp n film strips, usually, it is necessary to adjust the distance between the n groups of chucks to be smaller, that is, drive the n groups of chucks to approach each other, and then separate the n clamped film strips from each other by a predetermined interval. This predetermined interval is generally the distance between two adjacent film strip inserting stations.

[0077] The jacking device is located at the film strip inserting station, jacks up the front battery cell at the film strip inserting position in the battery string at the film strip inserting station, and forms an open film strip inserting position at the film strip inserting position.

[0078] The film strip handling device continues to move the transported film strips to the film strip inserting position. Since the film strip handling device can simultaneously clamp n film strips and can separate the n film strips by a predetermined interval, the film strip handling device can simultaneously insert the n film strips into the corresponding film strip inserting positions at n film strip inserting stations.

[0079] In summary, the film inserting device provided by the present application sets two film strip handling parts. By using multiple chucks on the film strip handling parts to simultaneously clamp both ends of n film strips, the clamping of multiple film strips is achieved. Moreover, by setting the movement of multiple chucks, the movement of the clamped n film strips is realized, which is applicable to the application scenario requirements during film strip feeding and film inserting. The picking and moving of the film strips are relatively simple, improving the efficiency of film inserting.

[0080] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the invention herein. This application is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include common general knowledge or conventional technical means in the technical field not invented by the present invention.
