Referring to fig. 1 to 6, the present utility model provides a novel glue head, comprising a hollow glue head body 100;

the inner cavity of the gluing head main body 100 comprises a first cavity 1, a second cavity 2 and a third cavity 3 which are distributed from top to bottom in sequence and are mutually communicated;

wherein the first chamber 1 is cylindrical in shape;

the top of the first chamber 1 is provided with a circular rubber pipe connecting port;

a cylindrical rubber outlet pipe 200 arranged on the outer rubber outlet equipment 400 (such as a rubber outlet machine) passes through the rubber outlet pipe connector from top to bottom and is then inserted into the inner cavity of the first chamber 1, and the rubber outlet pipe 200 of the rubber outlet equipment 400 is in surface contact with the first chamber 1;

wherein the second chamber 2 is an inverted cone-shaped chamber for locating the position of the cylindrical outlet tube 200 in the first chamber 1 (i.e. the outlet tube 200 is located in the first chamber 1 without moving down) and storing glue (in particular storing a part of the glue);

the cross-sectional diameter of the second chamber 2 decreases gradually from top to bottom;

the diameter of the circular top opening of the second chamber 2 is smaller than the diameter of the outlet pipe 200;

wherein the front view of the third chamber 3 is trapezoidal;

the top cross-sectional area of the third chamber 3 is smaller than the bottom cross-sectional area of the second chamber 2 (in particular significantly smaller, for example equal to one tenth of the bottom cross-sectional area of the second chamber 2);

the bottom of the third chamber 3 is provided with an arc-shaped glue outlet 4;

a third chamber 3 for delivering glue evenly distributed to the glue outlet 4;

the glue outlet 4 is used for discharging glue, so that the glue discharging shape of the glue is arc-shaped (namely, the glue with the arc-shaped glue discharging shape is discharged outwards) and is smeared on an arc-shaped surface 301 (namely, an arc-shaped groove surface) on the water cooling plate 300 of the battery module;

the glue outlet 4 is positioned right above an arc-shaped surface 301 (namely an arc-shaped groove surface) on a water cooling plate 300 of the battery module to be coated with glue;

the shape and size of the glue outlet 4 are correspondingly matched (specifically consistent) with the shape and size of the arc-shaped surface 301 (namely, the arc-shaped groove surface) on the water cooling plate 300 of the battery module to be coated with glue.

In the present utility model, it should be noted that the external glue dispensing apparatus 400 (such as a glue dispenser) has a cylindrical glue dispensing tube 200 for delivering glue to be applied to the glue head main body 100.

In the utility model, in particular implementation, the rubber outlet pipe 200 of the external rubber outlet machine is inserted into the rubber outlet pipe connecting port at the top of the first chamber 1.

In the utility model, in particular implementation, the rubber outlet pipe 200 of the rubber outlet device 400 is in interference fit with a rubber outlet pipe connector at the top of the first chamber 1.

In the present utility model, the first chamber 1 is a cylindrical chamber, and is connected to the cylindrical glue outlet pipe 200 in the glue outlet apparatus 400 located outside in a surface contact manner, and the mating type is a tight fit. The surface contact specifically means: the outer surface of the outlet pipe 200 is in contact with the inner surface of the first chamber 1, and the tight fit means that: the two contact surfaces are tightly matched (i.e. interference fit) so as to ensure that the glue does not overflow from the contact surfaces of the two.

In the present utility model, since the second chamber 2 is an inverted cone-shaped chamber, the cylindrical outlet pipe 200 cannot enter the second chamber 2, thereby positioning the cylindrical outlet pipe 200 at the interface of the first chamber 1 and the second chamber 2.

It should be noted that the second chamber 2 may also store a portion of glue. This is because: the second chamber 2 is an inverted cone-shaped chamber with a certain volume, and the top cross-sectional area of the third chamber 3 is smaller than the bottom cross-sectional area of the second chamber 2, so that part of glue can be stored in the second chamber 2.

It should be noted that, as shown in fig. 4, the second chamber 2 stores a portion of glue for: the glue water in the range from the position A to the position B can enter the third cavity 3 at the same time, and the glue distribution of the glue outlet 4 is ensured to be uniform. If the glue of the glue outlet pipe 200 directly enters the third chamber 3, the glue outlet diameter of the glue outlet pipe 200 is small (smaller than the distance from A to B), the glue will flow along the vertical direction of the connecting line from A to B, and will not flow along the direction from A to B (i.e. the transverse horizontal direction), so that only part of the glue is discharged from the arc outlet in the glue outlet 4.

In particular, in the present utility model, the glue provided by the glue dispensing device 400 is semi-liquid semi-solid glue, for example, a two-component epoxy resin AB glue which is well known in the art and mature in technology.

In the utility model, the front side and the rear side of the third chamber 3 are parallel to each other and are vertical planes;

the left side and the right side of the third chamber 3 are axisymmetrically distributed;

the cross-sectional diameter of the third chamber 3 increases gradually from top to bottom.

That is, the third chamber 3 is a flat trapezoidal chamber.

In particular, the third chamber 3 has an equal longitudinal width from top to bottom.

In the present utility model, it should be noted that the third chamber 3 is a flat trapezoidal chamber, and the glue in the second chamber 2 may be uniformly distributed at the arc-shaped glue outlet 4 after passing through the third chamber 3.

It should be noted that, as shown in fig. 4, for the second chamber 2, the length from the position a to the position B is smaller than the length from the position C to the position D, in order to convey glue evenly distributed to the position of the glue outlet 4 (i.e. glue is all located between the position C and the position D), the third chamber 3 is set to be flat, after the glue enters the third chamber 3, the glue is spread to both sides of the position C and the position D in the process of moving the glue to the glue outlet 4 due to the pressure of the glue gun (i.e. the glue outlet pipe 200 of the glue outlet device 400), and after the glue reaches the glue outlet 4, the glue is distributed on the arc-shaped glue outlet.

According to the utility model, the glue on the arc-shaped surface 301 of the water cooling plate 300 of the battery module can be uniformly distributed by conveying the glue uniformly distributed to the position of the glue outlet 4, so that the adhesion consistency of each cylindrical battery in the water cooling plate 300 is ensured to be good.

In a specific implementation of the utility model, the third chamber 3 has a vertical length that is greater than the longitudinal width of the third chamber 3.

It should be noted that, referring to fig. 4, the third chamber 3 is a flat trapezoidal chamber, where the longitudinal width (i.e. thickness) is t, the vertical length is s, and since t is smaller and s is larger (i.e. t is significantly smaller than s), it is ensured that the glue is uniformly distributed when reaching the arc-shaped glue outlet 4 after passing through the third chamber 3. The glue outlet 4 has an arc shape, and is consistent with the arc shape of the required glue coating surface (namely, the arc surface 301, namely, the arc groove surface) of the serpentine water-cooled plate 300, so that the glue can be uniformly distributed on the arc surface 301 of the serpentine water-cooled plate 300 when the glue is coated along the axial direction of the arc surface.

It should be noted that, as shown in fig. 4, for the second chamber 2, the length from the position a to the position B is smaller than the length from the position C to the position D, in order to convey glue evenly distributed to the position of the glue outlet 4 (glue is distributed from the position C to the position D), the third chamber 3 is set to be flat, after the glue enters the third chamber 3, the longitudinal width (i.e. thickness) t of the third chamber 3 is smaller, the glue can be spread to both sides of the position C and the position D simultaneously due to the pressure of the glue gun (i.e. the glue outlet pipe 200 of the glue outlet device 400), and the glue can be spread to both sides of the position C and the position D due to the large vertical length s of the third chamber 3, so that the glue is distributed to both sides of the position C and the position D after the glue reaches the glue outlet 4.

In specific implementation, the ratio of s to t may be preset and adjusted accordingly depending on the viscosity of the glue, which is not described herein, and generally requires t to be significantly smaller than s.

In addition, based on the novel glue spreading head provided by the utility model, referring to fig. 7, the utility model also provides a novel glue spreading structure, which comprises the novel glue spreading head and a water cooling plate 300 of the battery module;

a plurality of arc surfaces 301 (i.e., arc groove surfaces) are provided at the top of the water cooling plate 300 of the battery module;

the arc-shaped surface 301 is used for applying glue by the novel glue applying head.

In particular, the shape and size of the arc-shaped surface 301 are correspondingly matched with the shape and size of the circumferential curved surface of the cylindrical battery cell included in the battery module (for example, the diameter of the arc-shaped surface 301 is the same as the diameter of the cylindrical battery cell).

In addition, based on the novel glue head provided by the present utility model, referring to fig. 8, the present utility model also provides a glue coating system, which includes the novel glue head as described above, and a glue discharging device 400 (such as a glue discharging machine),

a cylindrical glue outlet pipe 200 arranged on a glue outlet device 400 (such as a glue outlet machine) is in sealing connection with a first cavity 1 arranged on a glue coating head main body 100 in the novel glue coating head;

glue outlet device 400 (e.g. glue outlet machine) is used for delivering glue to first chamber 1 in the novel glue spreading head, and driving glue to flow along first chamber 1, second chamber 2 and third chamber 3 to glue outlet 4 in sequence, and finally flow outwards (e.g. to arc-shaped surface 301 arranged at the top of water cooling plate 300 of the battery module).

In particular, one end of the glue outlet pipe 200 is communicated with a glue outlet in a glue storage cavity in the glue outlet device 400 (such as a glue outlet machine);

the other end of the rubber outlet pipe 200 is connected with the first cavity 1 in the novel gluing rubber head in a sealing way.

In specific implementation, the glue discharging device 400 (such as a glue discharging machine) is mature equipment in the prior art, for example, the glue discharging machine in the patent can be adopted to be a model MY-3200D dynamic AB glue discharging machine manufactured by the product of the fine dispensing consumable company.

In order to more clearly understand the technical scheme of the present utility model, the working principle of the present utility model is described below.

For the utility model, firstly, glue passes through external glue outlet equipment (such as a glue outlet machine), passes through a cylindrical glue outlet pipe 200 to reach a second cavity 2, and is uniformly distributed at an arc-shaped glue outlet 4 at the bottom of a novel glue coating head through a trapezoid cavity structure of a third cavity 3, and then is coated on any arc-shaped surface 301 at the top of a serpentine water cooling plate 300, and through the process, the state of the glue on the serpentine water cooling plate 300 can be in an arc-shaped state, and along with the glue coating head along the axial direction of the arc-shaped surface 301, the glue can be uniformly distributed on the arc-shaped surface in the water cooling plate by moving from the head end to the tail end (such as the left end to the right end of the arc-shaped surface 301 shown in fig. 7) of the arc-shaped surface 301.

Then, glue is applied to the plurality of arc surfaces 301 in sequence, and finally the glue application operation of the whole water-cooling plate 300 is completed.

Therefore, compared with the existing conventional smearing mode, the utility model can finish the uniform smearing operation of glue on the arc-shaped surface 301 by moving the smearing device for one time, obviously saves the action required to be performed, ensures the uniform smearing on the arc-shaped surface and improves the gluing efficiency to a great extent.

In summary, compared with the prior art, the novel gluing structure and the gluing system provided by the utility model are scientific in design, can enable the glue outlet shape of the glue applied on the arc-shaped surface of the water-cooling plate of the battery module to be arc-shaped, can conveniently and reliably uniformly apply the glue on the arc-shaped surface of the water-cooling plate of the battery module, can obviously improve the gluing efficiency and ensure the gluing quality compared with the existing gluing mode, thereby effectively saving precious labor cost, reducing the overall production cost of the battery module, and has great practical significance.

The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
