[0008] the skirt edge of the battery cell enters the glue applying cavity from the front end of the glue applying portion through the glue applying port and moves towards the rear end of the glue applying portion, wherein the opening of the glue applying port gradually decreases in the direction from the front end of the glue applying portion to the rear end of the glue applying portion.

[0009] The glue head according to the embodiment of the first aspect of the present application has at least the following beneficial effects: compared with the prior art, the glue head of the present application stores glue in the glue cavity, and the upper and lower surfaces of the skirt edge of the battery cell can be glued at the same time after the skirt edge enters the glue cavity, and the UV glue does not pollute the surface of the battery cell after gluing, thereby improving the qualified rate of the battery cell; in the present application, the opening of the glue outlet gradually decreases from the front end of the glue applying part to the rear end of the glue applying part, so that the skirt edge of the battery cell can more easily enter the glue cavity, and the battery cell is glued from the large opening of the horn-shaped part to the small opening at the tail, thereby avoiding the skirt edge of the battery cell from carrying a large amount of glue and forming a large head of glue.

[0053] The embodiments of the present application will be further described below with reference to the drawings.

[0054] First aspect embodiment

[0055] With reference to Figures 1 to 5 , the present application provides a preferred embodiment of a gluing head 10.

[0056] As Figure 1 shown, the gluing head 10 comprises a mounting seat 100, the upper part of the mounting seat 100 is used to connect the equipment to fix the gluing head 10. The lower part of the mounting seat 100 extends downwardly to provide a gluing part 101, and the gluing part 101 is provided with a gluing cavity 200 extending through the front and rear.

[0057] As Figure 4 and Figure 5As shown, the upper part of the mounting seat 100 is provided with a glue injection port 110, and the inside of the mounting seat 100 is provided with a main channel 120 communicating with the glue injection port 110, which extends downward into the inside of the glue applying part 101. In this embodiment, the glue injection port 110 and the main channel 120 are preferably vertically arranged. The inside of the glue applying part 101 is provided with a branch channel 130 communicating with the main channel 120 and the glue applying cavity 200. In this embodiment, the branch channel 130 is horizontally arranged. In use, the glue is supplemented into the glue applying head 10 through the glue injection port 110 on the mounting seat 100, and the glue reaches the inside of the glue applying cavity 200 after passing through the main channel 120 and the branch channel 130, so as to complete the glue applying operation in the glue applying cavity 200.

[0058] As shown, Figure 5 It is easy to understand that, in this embodiment, two branch channels 130 are arranged, and the two branch channels 130 are arranged above and below the glue applying cavity 200, respectively. The outlet of the branch channel 130 arranged above is opened at the top of the glue applying cavity 200, and the outlet of the branch channel 130 arranged below is opened at the bottom of the glue applying cavity 200. The top and bottom of the glue applying cavity 200 are communicated with the branch channels 130 for glue supplementing, which can ensure the uniform distribution of the glue in the glue applying cavity 200 and avoid the situation that one of the upper and lower surfaces of the cell skirt is insufficiently coated with glue.

[0059] Of course, in other embodiments, one or more branch channels 130 can also be arranged according to the situation, and the outlet of the branch channel 130 can also be arranged on the side wall of the glue applying cavity 200, which is not limited in the present application.

[0060] As shown, Figure 2 and Figure 3 The glue applying cavity 200 is a cavity penetrating through the front end and the rear end of the glue applying part 101, and one side of the glue applying cavity 200 is provided with a glue applying port 210, which is arranged for the cell skirt to be inserted into the glue applying cavity 200 for glue applying. In the present application, the glue applying cavity 200 has a C-shaped longitudinal cross section, and the glue applying port 210 is arranged at a position higher than the bottom of the glue applying cavity 200 and lower than the top of the glue applying cavity 200, as shown. Figure 5 The glue applying cavity 200 with the above-mentioned C-shaped structure can well store the glue in the cavity, and after the cell skirt enters the glue applying cavity 200 through the glue applying port 210, it is just located in the middle of the glue applying cavity 200, so that the upper and lower surfaces of the cell skirt can be simultaneously coated with glue, and after the glue applying, the UV glue will not scatter and pollute the surface of the cell, thereby improving the qualified rate of the cell quality.

[0061] As shown, Figure 3As shown, in this embodiment, the glue-applying port 210 gradually decreases in size from the front end to the rear end of the glue-applying section 101, forming a flared opening 211. The flared opening 211, wider at the front and narrower at the rear, facilitates the entry of the battery cell skirt into the glue-applying chamber 200. During glue application, the battery cell skirt enters from the wider flared opening and the opening narrows towards the rear, preventing excessive glue from being carried out by the skirt, avoiding the formation of large-head glue, improving the utilization rate of the glue for sealing the battery cell skirt, and saving glue.

[0062] In addition, those skilled in the art can, as needed, set the inlet end of the adhesive applicator 210 as an arc-shaped opening or a conical opening. This application does not specifically limit the shape of the inlet end opening of the adhesive applicator 210.

[0063] like Figure 3 As shown, in this embodiment, an overflow groove 220 is provided at the rear end of the adhesive application section 101, and the overflow groove 220 is connected to the adhesive application chamber 200. Because of the overflow groove 220, excess adhesive will flow out from the overflow groove 220 during adhesive application, preventing blockage of the adhesive application chamber 200 and avoiding pollution of the surrounding environment. Furthermore, during adhesive removal, the overflow groove 220 facilitates the outflow of adhesive from the adhesive application chamber 200, enabling better adhesive removal and preventing adhesive blockage of the adhesive application chamber 200. Since the battery cell skirt moves from the front end to the rear end of the adhesive application section 101, it is easy to carry adhesive towards the rear end of the adhesive application section 101. Therefore, placing the overflow groove 220 at the rear end of the adhesive application section 101 helps to guide the adhesive carried backward.

[0064] like Figure 2 and Figure 3 As shown, in this embodiment, an overflow groove 220 is also provided at the front end of the adhesive coating section 101, and the overflow groove 220 is connected to the adhesive coating cavity 200. When the battery cell skirt enters the adhesive coating cavity 200 from the front end of the adhesive coating section 101, it will squeeze out some of the adhesive located at the front end of the adhesive coating cavity 200. Therefore, setting the overflow groove 220 at the front end of the adhesive coating section 101 is beneficial for guiding the adhesive that has been squeezed out of the adhesive coating cavity 200.

[0065] It is easy to imagine that a glue recycling mechanism could be connected to the rear of the glue overflow tank to collect the overflowing glue for recycling, thereby reducing material waste and saving costs.

[0066] Furthermore, refer to Figure 2 In this application, the inner walls of the glue application cavity 200 and the glue overflow tank 220 are preferably made of arc-shaped surfaces to reduce the appearance of sharp corners, facilitate the flow of glue, avoid glue accumulation, and improve the glue removal effect.

[0067] Second aspect of the embodiment

[0068] With reference to Figure 6 and Figure 7 The application also provides a preferred embodiment of a gluing device, which comprises a frame, a gluing mechanism, a visual positioning mechanism, a clamp 50 and a controller arranged on the frame.

[0069] As shown in Figure 6 , the gluing mechanism comprises a glue injector, the gluing head 10 of the first aspect of the application and a driving mechanism for driving the gluing head 10 to move. The driving mechanism comprises an X-axis driving mechanism 21, a Y-axis driving mechanism 22 and a Z-axis driving mechanism 23. Through the driving mechanism of the three different axes, the gluing head 10 can move in multiple directions, so that the gluing head 10 can be accurately moved to the position of the battery cell and automatically glue. One end of the glue injector is connected to a device for storing glue, and the other end of the glue injector is connected to the glue injection port 110 of the gluing head 10. The glue injector is provided with a valve for controlling the outflow of glue. The glue injector injects glue into the inside of the gluing head 10 through the glue injection port 110. The glue successively passes through the main channel 120 and the branch channel 130 and reaches the inside of the gluing cavity 200.

[0070] As shown in Figure 7 , the clamp 50 is used to clamp and fix the battery cell and make the skirt edge of the battery cell face outward. Preferably, the clamp 50 is movably arranged on the gluing device, which facilitates feeding and discharging.

[0071] As shown in Figure 7 , the visual positioning mechanism is arranged near the clamp 50 and is used to visually position the battery cell clamped by the clamp 50. In this embodiment, the visual positioning mechanism comprises a camera assembly 40 and a light source assembly 41. The camera assembly 40 is arranged above the clamp 50 and downwardly photographs, and the light source assembly 41 is arranged below the clamp 50 and upwardly irradiates. The camera assembly 40 is used to photograph the battery cell fixed on the clamp 50, which can provide accurate image data, so that the controller can analyze the distance between the skirt edge of the battery cell and the gluing head 10. The light source assembly 41 is arranged to cooperate with the camera assembly 40 above to photograph and can also accurately position in the case of insufficient ambient light.

[0072] With reference to Figure 7 , in this embodiment, the camera assembly 40 is provided in multiple numbers. The multiple camera assemblies 40 can provide more angle images to construct a model closer to reality and provide more accurate data for the controller to analyze. Of course, the number of the camera assembly 40 is not limited in the application, and a person skilled in the art can also arrange only one camera assembly 40 according to the need.

[0073] Preferably, in the embodiment, the camera assembly 40 is a CDD camera. The CDD camera is a high-precision camera used in industrial control equipment, which is one of the preferred embodiments of the present application. Of course, the present application does not limit the type of camera assembly 40, and those skilled in the art can select different types of camera assembly 40 as needed.

[0074] It is easily conceivable that the controller is connected to the visual positioning mechanism and the driving mechanism respectively. When the visual positioning mechanism sends the photographed battery image data to the controller, the controller analyzes the distance between the battery and the glue head 10, and adjusts the action of each driving mechanism according to the distance between the battery skirt and the glue head 10. For example, the X-axis driving mechanism 21 first drives the glue head 10 to move along the X-axis, so that the battery skirt enters the glue cavity 200 from the horn 211 at the front end of the glue applying part 101, and then the Y-axis driving mechanism 22 drives the glue head 10 to move along the Y-axis to apply glue to the battery skirt.

[0075] Further, referring to Figure 6 and Figure 7 , the glue applying device of the embodiment further comprises a glue removing mechanism, which comprises a waste collecting box 30 and a blowing port. The waste collecting box 30 is a closed box body, and an opening is formed in the upper part of the waste collecting box 30 for the glue applying part 101 to extend into. The blowing port is arranged inside the waste collecting box 30, and is connected to a blowing device through a pipeline. The blowing port is used to blow air to the glue applying part 101 extending into the waste collecting box 30, so as to remove the residual glue on the surface of the glue applying part 101 and inside the glue cavity 200. In the embodiment, after the glue head 10 completes the glue applying operation, the controller controls the driving mechanism to drive the glue head 10 to separate from the battery skirt and move above the waste collecting box 30 of the glue removing mechanism. The Z-axis driving mechanism 23 drives the glue head 10 to move downward along the Z-axis, so that the glue applying part 101 extends into the waste collecting box 30, and the blowing port blows air to the horn 211 on the glue applying part 101, so as to ensure that the air volume is consistent before and after, and the residual glue inside the entire glue cavity 200 can be removed completely, avoiding that the residual glue is solidified to block the glue cavity 200. The blown glue is collected by the waste collecting box 30 and recycled, reducing material loss and saving cost.

[0076] The gluing device of the scheme utilizes the clamp 50 to fix the battery cell, simultaneously utilizes the visual positioning mechanism to obtain the position information of the battery cell, controls the driving mechanism to act through the controller, and enables the gluing head 10 to precisely glue the skirt edge of the battery cell, realizes automatic gluing, and can utilize the glue removing mechanism to automatically remove the residual glue on the gluing part 101 and the gluing cavity 200 after gluing, has high degree of automation, and has high production efficiency. Since the gluing head 10 of the application adopts the C-shaped gluing cavity 200, the glue is inside the gluing cavity 200, the upper and lower two surfaces of the skirt edge of the battery cell can be glued after the skirt edge of the battery cell enters the gluing cavity 200, and the UV glue does not produce scattered point pollution on the surface of the battery cell after gluing, and the qualified rate of the battery cell quality is improved.

[0077] The above is a specific description of the preferred implementation of the application, but the application is not limited to the above implementation, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the application.
