[0031] The battery pack is cooled by a cooling plate, and the cooling plate is mostly made of metal. In order to ensure the insulation of the cooling plate, an insulating film needs to be attached to the cooling plate. In the related art, the insulating film is attached by an assembler by hand, and one side of the insulating film is attached to the cooling plate to achieve the insulation effect. However, the attached insulating film has a certain peeling property, and different degrees of warping and bulging may occur due to high temperature and time. In addition, manual pressing of the insulating film is not only low in efficiency but also cannot guarantee that the insulating film is pressed in place without bulging, and manual pressing may cause dirt, unevenness and other quality problems.

[0032] In view of this, the utility model provides a film pasting device 100, Figures 1 to 5 The film pasting device 100 provided by the utility model has the advantages of simple structure, accurate attachment of the insulating film to the cooling plate, and avoidance of warping and other problems. The film pasting device 100 will be described in detail below in combination with the main drawings.

[0033] Please refer to Figure 1 A film pasting device 100 is used for attaching an insulating film to a cooling plate. The film pasting device 100 comprises a hand-held frame 1 and two film pressing rollers 2. The hand-held frame 1 has two oppositely arranged mounting ends. The two film pressing rollers 2 are respectively mounted on the two mounting ends, and the two film pressing rollers 2 are coaxially arranged.

[0034] In the technical scheme of the utility model, the two film pressing rollers 2 are respectively mounted on the two mounting ends of the hand-held frame 1, and the two film pressing rollers 2 can simultaneously perform roller pressing to attach two insulating films to two cooling plates, thereby improving the installation efficiency and saving time. Compared with the manual film pasting method in the related art, the film pasting device 100 of the utility model uses the film pressing roller 2 to perform roller pressing to attach the insulating film to the cooling plate, which can solve the problem of warping and air bubbles caused by manual film pasting in the related art, and can also avoid the problem of leaving fingerprints and dust in manual film pasting operation, thereby improving the film pasting efficiency and the yield of products.

[0035] In some embodiments, the film pasting device 100 can simultaneously attach two insulating films to two cooling plates. Specifically, the two cooling plates are placed side by side, and the two film pressing rollers 2 simultaneously attach the two insulating films to the corresponding cooling plates. When the roller pressure is too heavy, as the two film pressing rollers 2 are coaxially arranged, as long as one of the film pressing rollers 2 corresponds to one of the cooling plates, the other film pressing roller 2 automatically corresponds to the other cooling plate, so that the two insulating films can be synchronously attached, thereby saving the alignment time and improving the work efficiency.

[0036] The specific type of the handheld frame 1 is not limited and can be selected according to actual conditions. In some embodiments, the handheld frame 1 includes a handle 11 and two connecting members 12. The handle 11 is used for the operator to grasp. In order to facilitate the operator to grasp, the handle 11 is a cylindrical handle.

[0037] Furthermore, the handle 11 has a first end 113 and a second end 114 disposed opposite each other, with two connectors 12 detachably connected to the first end 113 and the second end 114, respectively. The two lamination rollers 2 are rotatably mounted on the ends of the two connectors 12 facing away from the handle 11. When the operator only needs to apply an insulating film to a cooling plate, either connector 12 can be removed from the handle 11, facilitating operation. If the lamination roller 2 becomes damaged or stuck, the connector 12 can also be removed from the handle 11 for replacement or repair, making operation more convenient and quick.

[0038] by Figure 1 Taking the first direction as an example, the second direction intersects the first direction in the horizontal plane.

[0039] See also Figure 2 and Figure 3 Each connecting member 12 includes a support rod 120 , one end of each support rod 120 is mounted with the lamination roller 2 , and the other end of each support rod 120 is detachably mounted on the second rod 112 .

[0040] For more details, please refer to Figure 2 and Figure 3 Each support rod 120 further includes a third rod 121 and a fourth rod 122 connected thereto. The third rod 121 extends in the second direction and engages with the handle 11, being detachably attached thereto. The fourth rod 122 extends in the first direction and is mounted on the lamination roller 2. This arrangement increases the spacing between the two connecting members 12, allowing the lamination device 100 to accommodate larger cooling plates.

[0041] Please continue reading Figure 3 The connecting member 12 also includes a fifth rod, which extends along the second direction and is arranged at an end of the fourth rod 122 away from the third rod 121. Two connecting rods are respectively provided at both ends of the fifth rod. Rotating holes are formed on the two connecting members 12. The rotating shaft of the laminating roller 2 is rotatably installed on the two connecting members 12 through the two rotating holes, thereby realizing the rotatable installation of the laminating roller 2 and the connecting member 12.

[0042] Further, in order to ensure the balance of stress, in some embodiments, the fourth rod 122 is connected at the middle position of the fifth rod, so that the film pressing roller 2 is located at the middle position of the fourth rod 122, so that the film pressing roller 2 can be balanced in stress, the rolling process is more stable, and deviation due to uneven stress during roller pressing is avoided.

[0043] In some embodiments, referring to the drawings, the handle 11 comprises a first rod 111 extending in a first direction and two second rods 112 extending in a second direction, the first rod 111 is arranged between the two second rods 112, and the ends of the two second rods 112 away from the first rod 111 are respectively a first end 113 and a second end 114; it should be noted that the connection position of the two second rods 112 is not limited and can be selected according to actual conditions.

[0044] Please continue to refer to Figure 5 In this embodiment, the first rod 111 has an end close to the film pressing roller 2 and an end away from the film pressing roller 2. In this embodiment, the main function of the film pasting assembly is to attach the insulating film to the cooling plate, so that the cooling plate is insulated. Therefore, during the pasting process, the integrity of the insulating film needs to be ensured, and the insulating film cannot be damaged. When the two second rods 112 are arranged at the middle or upper position of the first rod 111, a part of the first rod 111 will extend out, which is easy to touch the insulating film during the film pasting process, causing damage to the insulating film. In order to avoid the above situation, in this embodiment, the two second rods 112 are connected at the end of the first rod 111 close to the film pressing roller 2, so that not only the space can be reasonably utilized, but also the first rod 111 is prevented from touching the insulating film during the film pasting process, causing damage to the insulating film.

[0045] In some embodiments, the end of the second rod 112 away from the first rod 111 is formed with a receiving cavity 1121, and the third rod 121 is clamped in the receiving cavity 1121, so as to relatively fix the handle 11 and the connecting piece 12.

[0046] In order to make the film pasting device 100 adapt to different models, the two third rods 121 are movably arranged in the two receiving cavities 1121 in the second direction, so that the two connecting pieces 12 can be close to or away from each other. It should be noted that the connection mode of the third rod 121 and the receiving cavity 1121 is not limited.

[0047] In some embodiments, an internal thread is formed in the receiving cavity 1121, and an external thread is formed on the outer side wall of the third rod 121, the internal thread and the external thread are matched, and the third rod 121 is movably arranged in the receiving cavity 1121.

[0048] In some other embodiments, the cavity wall of the accommodating cavity 1121 is penetrated by a second through hole, the third rod 121 is provided with a plurality of threaded holes, and the plurality of threaded holes are arranged at intervals in a second direction; the plurality of threaded holes can correspond to the second through hole; the film pasting device 100 further comprises a fixing piece 4; when adjustment is needed, the position of the third rod 121 is adjusted so that one of the threaded holes on the third rod 121 corresponds to the second through hole, and the fixing piece 4 is threadedly connected to the corresponding threaded hole through the second through hole.

[0049] In some other embodiments, the film pasting device 100 further comprises a fixing piece 4, the cavity wall of the accommodating cavity 1121 is penetrated by a second through hole, the second through hole is a threaded hole, and the third rod 121 is clamped in the accommodating cavity 1121; when the clamping of the third rod 121 is completed, the fixing piece 4 is rotated in the second through hole until the fixing piece 4 abuts against the third rod 121, and at this time, the third rod 121 is fixed between the cavity wall of the accommodating cavity 1121 and the fixing piece 4.

[0050] Further, please continue to refer to Figure 3 and Figure 5 , the outer side wall of the third rod 121 is provided with a scale line 1211. When the third rod 121 is adjusted, the adjustment can be made according to the scale line 1211 on the third rod 121, so that the adjustment accuracy is higher. For example, when the third rod 121 is adjusted in a direction away from the second rod 112, the third rod 121 needs to be pulled out, and in the process of plugging, it is easy to overtake. At this time, according to the scale line 1211 of the third rod 121, the distance of plugging can be determined, and as long as the opening end of the accommodating cavity 1121 is aligned with the scale line 1211, accurate measurement can be realized.

[0051] In some embodiments, the outer side of the insulating film is further covered with an insulating protective layer, and when the insulating film is attached to the cooling plate, the insulating protective layer needs to be torn off for convenient operation. In the present embodiment, the film pasting device 100 further comprises a separating piece 3, and the separating piece 3 is located on the side of the film pressing roller 2 away from the connecting piece 12, and the separating piece 3 is used to separate the insulating film and the insulating protective film. In the actual operation process, the insulating protective film on one side of the insulating film is first torn off, the insulating film is placed on the cooling plate, and at the same time, the film pressing roller 2 is placed above the insulating film. The insulating protective film is connected with the separating piece 3, and when the film pressing roller 2 rolls on the cooling plate, the film pressing roller 2 attaches the insulating film to the cooling plate. In the rolling process, the separating piece 3 moves with the movement of the film pressing roller 2, thereby separating the insulating protective film from the insulating film. Such a setting simplifies the operation steps and improves the production efficiency.

[0052] Further, in some embodiments, the separating piece 3 is rotatably installed at both ends of the film pressing roller 2, so that the angle of the separating piece 3 can be adjusted. According to the actual situation, the angle of the separating piece 3 is adjusted to avoid interference of the separating piece 3 with the film pressing roller 2 and affect the attachment effect of the insulating film.

[0053] It should be noted that the specific type of the separator 3 is not limited and can be selected according to the actual situation. Figure 3 and Figure 4 In some embodiments, the separator 3 includes a separator plate 32 and two connecting plates 31. The separator plate 32 is positioned between the two connecting plates 31, which are rotatably mounted on both ends of the lamination roller 2. The separator plate 32 is formed with a first through-hole 321 for the protective film to pass through. In actual operation, the insulating protective film on one side of the insulating film is first torn off and placed in the first through-hole 321. As the lamination roller 2 advances, the separator 3 moves with it, driving the insulating protective film forward, thereby separating the insulating protective film from the insulating film.

[0054] In some embodiments, the film-mounting device 100 further includes a positioning device, which is fixed at the mounting end and is used to detect the position of the insulating film.

[0055] More specifically, the positioning device is a laser transmitter, and the laser generator includes a transmitter and a receiver. The transmitter is provided on the connecting member 12 and is located at one end of the connecting member 12 close to the film pressing roller 2. During the rolling of the film pressing roller 2, the transmitter can emit laser light and the receiver can receive laser light. When the film laminating device 100 is offset, the transmitter also offsets, and the receiver cannot receive the signal, causing the laser to disappear, thereby reminding the operator that the film laminating device 100 is offset. The operator needs to adjust the film laminating device 100 to a suitable position before continuing to complete the film laminating.

[0056] The present invention also provides a robotic arm, which includes a film laminating device 100. The specific structure of the film laminating device 100 is referred to the above embodiment. Since the present robotic arm adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] Specifically, in this embodiment, an installation portion is formed on the robotic arm, and the film-sticking equipment is installed on the robotic arm. The film is stuck by the robotic arm, and the robotic arm can control the force of the film sticking so that the insulating film can be tightly adsorbed on the cooling plate, resulting in higher product quality and better production efficiency.
