[0002] As a key component of modern green energy technology, new energy batteries are widely used in electric vehicles, energy storage systems and other fields. Their performance and safety directly affect the efficiency of the entire system. New energy batteries are usually composed of multiple independent battery cells. This modular design not only improves the energy density of the battery, but also facilitates production and maintenance.

[0003] However, direct contact and collision between battery cells, especially when the battery pack is subjected to external force impact, may cause battery cell damage, short circuit or even thermal runaway, seriously threatening the safety and service life of the battery. Therefore, a battery rack is usually provided on the outside of the battery cell to facilitate the fixation and assembly of the battery cell.

[0004] In order to further improve the buffering effect and enhance the protective effect of the cell frame on the battery cell, a buffer layer or protective glue is usually attached to the contact surface between the cell frame and the battery cell to avoid rigid contact between the cell frame and the battery cell. However, the existing equipment can usually only apply protective glue on a single surface of the cell frame. When it is necessary to apply glue on the reverse side, the cell frame needs to be manually flipped, which is not conducive to the automated production of the equipment. Summary of the invention

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0045] In order to further improve the buffering effect and enhance the protective effect of the cell frame on the battery cell, a buffer layer or protective glue is usually attached to the contact surface between the cell frame and the battery cell to avoid rigid contact between the cell frame and the battery cell. However, the existing equipment can usually only apply protective glue on a single surface of the cell frame. When it is necessary to apply glue on the reverse side, the cell frame needs to be manually flipped, which is not conducive to the automated production of the equipment.

[0046] The invention provides an attaching device for attaching protective glue to a battery frame.

[0047] See also Figure 1 and Figure 2 In one embodiment of the present invention, the attaching device 100 includes:

[0048] Rack 1;

[0049] The conveying mechanism 2 is installed on the frame 1 and is used to convey the battery rack;

[0050] The front side attaching mechanism 3 is installed on the frame 1 and is used to attach protective glue to the front side of the battery frame;

[0051] The flipping mechanism 4 is disposed on one side of the front side attaching mechanism 3 and is used to flip the battery frame after the front side adhesive bonding is completed so that the back side of the battery frame faces upward; and

[0052] The back side attaching mechanism 5 is arranged at one side of the front side attaching mechanism 3 and is used for attaching protective adhesive to the back side of the battery cell frame flipped by the flipping mechanism 4 .

[0053] In the technical solution of the present invention, the conveying mechanism 2 is used to convey the battery frame, so that the front side of the battery frame is affixed with protective glue by the front side attaching mechanism 3, and then turned over by the flipping mechanism 4, and then the back side is affixed with protective glue by the back side attaching mechanism 5, thereby achieving the front and back attachment effect of the battery frame, ensuring that the protective glue is evenly and firmly attached to the front and back sides of the battery frame, and improving the overall quality and durability of the product. The attaching device 100 integrates multiple functions such as automatic conveying, front side attaching, flipping and back side attaching, and realizes the fully automatic operation of attaching protective glue from the front to the back of the battery frame, greatly improving the degree of production automation. In this solution, by setting the flipping mechanism 4, the attaching device 100 can achieve fast and accurate gluing, significantly improving the overall production efficiency of attaching protective glue to the battery frame, and shortening the production time.

[0054] Specifically, the types of the front side attaching mechanism 3 and the back side attaching mechanism 5 are not specifically limited, for example, they can be structures such as glue sticking manipulators, or structures such as pressing cylinders, as long as they can perform uniform glue sticking. The flipping mechanism 4 can be a crank connecting rod mechanism, or a universal joint mechanism, as long as it can flip the battery rack and has the function of flipping the battery rack from the front side to the back side, for example, it can be a conventional mechanical 180-degree flipping mechanism 4 or a flap mechanism.

[0055] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , the front attachment mechanism 3 comprises:

[0056] The first glue dispensing component 31 is disposed above the conveying mechanism 2 and is used to apply adhesive to the front of the battery frame; and

[0057] The first glue sticking component 32 is disposed on one side of the first glue dispensing component 31 and is used to stick protective glue to the front side of the battery frame, and the protective glue is bonded to the front side of the battery frame through an adhesive.

[0058] Specifically, the first glue dispensing component 31 is located above the conveying mechanism 2, and can accurately apply adhesive to the front of the battery frame, ensuring that the amount of adhesive used is moderate, avoiding waste, and ensuring the uniformity and consistency of bonding. Optionally, the first glue dispensing component 31 includes a glue gun and a three-axis moving component, so that the glue gun can move in three directions along the three-axis moving component to evenly apply adhesive to the front of the battery frame, so as to facilitate uniform bonding with the battery frame, and the bonding effect is more solid, which effectively improves the contact rigidity between the battery frames and between the battery frames and the battery cells, and avoids damage to the battery cells. The first glue assembly 32 works in coordination with the first glue dispensing component 31, so that the protective glue can be accurately bonded to the front of the battery frame through the adhesive, thereby improving the accuracy and stability of the attachment and reducing errors caused by manual operation.

[0059] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 , the back side attaching mechanism 5 comprises:

[0060] The second glue dispensing component 51 is disposed above the conveying mechanism 2 and is used to apply adhesive to the reverse side of the battery frame; and

[0061] The second glue sticking component 52 is disposed on one side of the second glue dispensing component 51 and is used to stick protective glue to the reverse side of the cell frame, and the protective glue is bonded to the reverse side of the cell frame through an adhesive.

[0062] Specifically, the second glue dispensing component 51 is located above the conveying mechanism 2, and can accurately apply adhesive to the back of the battery frame, ensuring that the amount of adhesive used is moderate, avoiding waste, and ensuring the uniformity and consistency of bonding. Optionally, the second glue dispensing component 51 has the same structure as the first glue dispensing component 31, and also includes a glue gun and a three-axis moving component, so that the glue gun can move in three directions along the three-axis moving component to evenly apply adhesive to the back of the battery frame, so as to facilitate uniform bonding with the battery frame, and the attachment effect is more firm, effectively improving the contact rigidity between the battery frames and between the battery frames and the battery cells, and avoiding damage to the battery cells. The second glue sticking component 52 works in coordination with the second glue dispensing component 51, so that the protective glue can be accurately bonded to the back of the battery frame through the adhesive, improving the accuracy and stability of the attachment, and reducing errors caused by manual operation.

[0063] In the embodiments of the present invention, please refer to Figure 1 and Figure 5 The attaching device 100 further includes a glue supply mechanism 6, which is installed on the frame 1 and located on one side of the conveying mechanism 2. The first glue assembly 32 and the second glue assembly 52 absorb the protective glue on the glue supply mechanism 6 and attach them to the battery frame. By providing the glue supply mechanism 6 in the attaching device 100, the first glue assembly 32 and the second glue assembly 52 can directly absorb the protective glue on the glue supply mechanism 6 and then attach it to the battery frame, which reduces the steps of manual picking, thereby significantly improving the production efficiency of the battery frame glue. It should be noted that the glue supply mechanism 6 may include a glue shaft, a tension wheel, a cutting assembly, a glue paper pulling mechanism and a stepping motor, etc. The use of the stepping motor realizes the automatic unwinding of the glue material, reducing manual intervention; the cooperation of the glue shaft and the tension wheel ensures the stable supply of the glue material during the unwinding process, avoiding the problem of uneven glue application caused by loose or too tight glue material; the setting of the cutting assembly allows the glue material to be accurately cut, ensuring that the length of the glue material attached each time is consistent, and improving the consistency and reliability of the glue application of the battery frame. The design of the glue paper pulling mechanism simplifies the process of pulling the glue material, and the operator only needs to perform simple operations to complete the pulling and application of the glue material, reducing the difficulty of operation.

[0064] In the embodiments of the present invention, please refer to Figure 3 The first adhesive component 32 and the second adhesive component 52 both include:

[0065] The mobile module 321 is installed on the frame 1; and

[0066] The adsorption plate 322 is movably disposed on the movable module 321 , and the adsorption plate 322 is linearly moved on the movable module 321 to adsorb the protective glue on the glue supply mechanism 6 and attach it to the battery frame.

[0067] Specifically, in order to facilitate the adhesive component to apply protective adhesive to the battery frame, the first adhesive component 32 and the second adhesive component 52 can be a structure including a moving module 321 and an adsorption plate 322. The moving module 321 can be a two-axis moving component or a three-axis moving component, that is, it can move along the three directions of the X axis, the Y axis and the Z axis; through the movement of the adsorption plate 322 on the moving module 321, the position and strength of the adhesive can be accurately controlled to ensure that the protective adhesive is evenly and accurately attached to the battery frame. In addition, the movable design of the adsorption plate 322 enables the adhesive component to adapt to battery frames of different sizes and shapes, thereby improving the versatility and flexibility of the equipment.

[0068] In the embodiments of the present invention, please refer to Figure 3 , the first adhesive component 32 and the second adhesive component 52 also include a buffer 323, and the buffer 323 is arranged between the mobile module 321 and the adsorption plate 322 to connect the mobile module 321 and the adsorption plate 322, which can effectively absorb and reduce the vibration caused by mechanical movement during the attachment process, and protect the battery frame and equipment components from damage. It should be noted that the buffer 323 can be an elastic structure with a buffering effect such as a spring. When the adsorption plate 322 contacts the battery frame, it will not hit the battery frame strongly, but will flexibly contact the battery frame under the elastic buffering force of the buffer 323 to protect the battery frame from damage.

[0069] In the embodiments of the present invention, please refer to Figure 4 , the turning mechanism 4 comprises:

[0070] A turning frame 41 is mounted on the frame 1; and

[0071] The turning fixture 42 is rotatably connected to the turning frame 41 and is used to clamp the battery cell frame.

[0072] Specifically, the flip frame 41 is installed on the frame 1, and the flip fixture 42 is rotatably connected thereto, which can ensure that the battery rack maintains precise alignment during the flipping process and reduce position deviation. The flip fixture 42 is used to clamp the battery rack, ensuring the stability and safety of the battery rack during the flipping process, reducing the risk of damage to the battery rack or personal injury caused by flipping, and making the process of attaching protective glue to the front and back of the battery rack continuous, without the need for manual flipping, greatly improving the operating efficiency of the production line. It should be pointed out that the structure of the flip fixture 42 is not specifically limited, and it can be a manipulator or a clamp, etc.

[0073] In the embodiments of the present invention, please refer to Figure 4 The flip mechanism 4 further includes a steering gear 43, which is mounted on the flip frame 41, and the flip fixture 42 is connected to the flip frame 41 through the steering gear 43. The setting of the steering gear 43 enables the flip fixture 42 to achieve precise angle positioning of the battery frame during the flipping process through precise steering control. For example, the steering gear 43 can be a 180-degree mechanical flip structure to achieve free switching between the front and back surfaces of the battery frame: the steering gear 43 can effectively control the flipping action, prevent the battery frame from falling off or being damaged due to flipping too fast or at too large an angle, and improve the safety of the operation process.

[0074] In the embodiments of the present invention, please refer to Figure 1 and Figure 6 The attaching device 100 also includes a cleaning mechanism 7, which is arranged on the side of the front attaching mechanism 3 away from the flipping mechanism 4; and / or, the cleaning mechanism 7 is arranged on the side of the back attaching mechanism 5 close to the flipping mechanism 4; wherein the cleaning mechanism 7 is located above the conveying mechanism 2 to clean and remove dust from the battery cell rack on the conveying mechanism 2.

[0075] Specifically, the cleaning mechanism 7 is arranged above the conveying mechanism 2, which can effectively clean and remove dust from the battery rack, ensure that the surface of the battery rack is clean and dust-free before the protective glue is applied, and improve the attachment quality and adhesion of the protective glue. For example, the cleaning mechanism 7 can be a cleaning cover arranged above the conveying mechanism 2, and a plurality of spaced brushes are arranged inside the cleaning cover, and the brushes are installed on the side of the cleaning cover facing the conveying mechanism 2 through a lifting structure such as a telescopic cylinder. In other words, when the conveying mechanism 2 conveys the battery rack to the bottom of the cleaning cover, the brushes will clean the battery rack to ensure the clean state of the battery rack during the conveying process. It should be pointed out that the cleaning mechanism 7 can be arranged only before the front attachment mechanism 3, or only before the back attachment mechanism 5. Preferably, the cleaning mechanism 7 is arranged before both the front attachment mechanism 3 and the negative attachment mechanism, so as to ensure that the front and back of the battery rack can be cleaned before the protective glue is applied, thereby improving the quality of the protective glue.

[0076] In an embodiment of the present invention, the attaching device 100 further includes a detection mechanism 8, which is disposed on a side of the front attaching mechanism 3 close to the flipping mechanism 4; and / or, the detection mechanism 8 is disposed on a side of the back attaching mechanism 5 away from the flipping mechanism 4; wherein the detection mechanism 8 is installed above the frame 1 to detect the battery rack to which the protective glue is attached. In order to detect the effect of the glue, a detection mechanism 8 may also be provided in the attaching device 100, which is disposed after the front attaching mechanism 3 or after the negative attaching mechanism, or the detection mechanism 8 may be disposed after both attaching mechanisms. It should be noted that the detection mechanism 8 may be an industrial camera or other visual detection structure, as long as it can detect the effectiveness of the protective glue attached to the surface of the battery rack, thereby ensuring that the attachment of the protective glue meets the quality standards, for example, it is necessary to detect whether there is a situation where the protective glue is missing on a part of the battery rack, or whether the glue is uneven.

[0077] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
