Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like.

In the power battery production process, partial components of the power battery are required to be connected and assembled in an adhesive mode, when the components are glued, gluing equipment is required to be used for gluing the surfaces to be glued of the components, the gluing equipment comprises a glue outlet device, glue conveying sources are used for uniformly coating glue conveyed by the glue outlet device on the surfaces to be glued, and the glue sources can be containers for storing the glue and used for providing the glue. The glue outlet is generally provided with a glue outlet, and when glue is applied, the glue outlet is parallel to or directly contacted with the surface to be coated, and the glue outlet or the workpiece to be coated moves to apply glue on the surface to be coated.

In the glue coating production operation requiring a certain width of the coated glue, a wide glue outlet device (i.e. a glue outlet device with a certain width of the glue outlet) is often required to be used for glue coating. In actual gluing production, the applicant finds that, because of the influence of factors such as the shape of part of the component (such as a U-shaped component), the gluing operation space, the gesture of the gluing equipment and other auxiliary equipment, the gluing is often required to be performed on the inclined surface to be glued, and at this time, the glue outlet of the glue outlet device is also required to be inclined, and the thickness of the glue surface with a certain width coated by the inclined glue outlet device is uneven in the width direction, so that the subsequent pasting and assembly precision of the workpiece are seriously influenced.

In some cases, in order to avoid the problem that the thickness of the glue surface coated by the wide glue outlet device is uneven in the width direction, the glue coating device is provided with a plurality of side-by-side glue outlet devices, each glue outlet device is provided with a glue outlet hole, and when the glue is coated, the side-by-side glue outlet devices coat a plurality of side-by-side glue strips on the glue surface to be coated so as to form the glue surface with a certain width. However, the adhesive surface is discontinuous in the width direction, so that an integral adhesive surface with a certain width cannot be formed, the integrity of the adhesive surface is damaged, and the adhesive stability of the adhesive surface is seriously affected. And gaps existing between adjacent adhesive tapes can form gas, impurities or other carry-over areas of the medium affecting the pasting requirements, and cannot meet the high-standard pasting requirements.

Based on the above consideration, the inventor of the application has designed a glue outlet device through research and verification, wherein the glue outlet device is provided with a plurality of glue runners for alternately splitting so as to uniformly split glue in an inner cavity of the glue outlet device, so that the thickness of a coated glue surface in the width direction is more uniform; meanwhile, a colloid converging area is formed between the tail ends of the colloid flow channels and the glue outlet, and the colloid uniformly split by the colloid flow channels is converged before flowing out through the glue outlet so as to coat the finished glue surface which has a certain width and has more uniform colloid thickness in the width direction.

Referring to fig. 1, and further referring to fig. 2 and 3, fig. 1 is an isometric view of a glue dispensing device 100 according to some embodiments of the present disclosure; fig. 2 is a front view of a glue dispensing apparatus 100 according to some embodiments of the present application; fig. 3 is a cross-sectional view of a glue dispensing apparatus 100 provided in some embodiments of the present application; the application provides a glue dispensing device 100, comprising: the body 10 is provided with an inner cavity 20, a glue inlet 30 and a glue outlet 40 which are communicated with the inner cavity 20, and the width of the glue outlet 40 is larger than that of the glue inlet 30; a plurality of partition walls 50 provided at intervals in the width direction of the glue outlet 40 in the inner chamber 20 so as to partition a plurality of parallel glue flow passages 21 in the inner chamber 20; wherein, a predetermined distance is provided between one end of each partition wall 50 near the glue outlet 40 and the glue outlet 40, so as to form a glue converging area 22 between the glue runners 21 and the glue outlet 40.

It can be appreciated that the glue inlet 30 of the body 10 is communicated with a glue source, the glue source can be a container for storing glue, the glue source provides glue for the glue outlet device 100, the glue enters the inner chamber 20 of the glue outlet device 100 through the glue inlet 30, and the glue flowing in the inner chamber 20 is split by the plurality of glue runners 21, so that the glue is more uniform in the inner chamber 20 along the width direction of the glue outlet 40.

The width direction of the glue outlet 40 corresponds to the width direction of the glue surface formed by the glue outlet 40 after glue coating, and the cross section of the glue outlet 40 may be rectangular, bar-shaped, etc.

The number of the partition walls 50 can be flexibly set according to the total width of the glue outlet 40 and the width of each glue channel, the number of the glue channels 21 is changed along with the change of the number of the partition walls 50, and each time the partition walls 50 are added, the glue channel is added one by one.

The end of each partition wall 50 close to the glue outlet 40 has a preset distance from the glue outlet 40, i.e. the end of each partition wall 50 close to the glue outlet 40 does not extend to the glue outlet 40, so that the glue converging area 22 is formed between the glue outlet 40 and the tail ends of the glue runners 21 of the internal chamber.

On the one hand, in the glue outlet device 100 of the embodiment of the present application, a plurality of glue flow channels 21 are provided in the body 10 along the width direction of the glue outlet 40, so as to split the glue entering the body 10 along the width direction of the glue outlet 40, so that the glue quantity of the glue outlet 40 in the width direction is more uniformly distributed, when the glue is applied on an inclined plane, the glue can be effectively buffered, in the body 10, due to the gravity factor, to the bottom of the body 10, the glue quantity of the glue outlet 40 has the problem that the upper end is thin and the lower end is thick, thereby effectively relieving the problem that the thickness of the glue surface coated by the glue outlet device 100 in the width direction is uneven; in a second aspect, a glue converging region 22 is formed between the glue runners 21 and the glue outlet 40 of the glue outlet device 100 in this embodiment, glue in the body 10 is split by the glue runners 21, and before the glue in the glue runners 21 flows out through the glue outlet 40, the glue can be mutually diffused and converged in advance in the glue converging region 22, and then flows out through the glue outlet 40, so as to coat a complete glue surface with a certain width, and avoid the glue surface being separated into a plurality of glue strips by the partition wall 50; the glue outlet device 100 of the embodiment of the application effectively relieves the problem that the glue surface is uneven in thickness in the width direction when the inclined plane gluing is carried out on the premise that the glue coating glue surface is complete, ensures the pasting area to ensure the pasting stability, and avoids the problem that the follow-up assembly precision is influenced due to uneven glue coating thickness.

Optionally, the preset distance is 2-5 mm.

The preset distance refers to a linear distance between one end of the partition wall 50, which is close to the glue outlet 40, and a plane where the glue outlet 40 is located, that is, a height of the glue converging area 22 perpendicular to the width direction of the glue outlet 40.

The size of the preset interval directly influences the uniformity effect on the width direction of the colloid and the integrity of the colloid surface, if the preset interval is too small, the colloid may not reach the mutual diffusion and confluence after flowing out of the colloid flow channel 21 to directly form a plurality of colloid surfaces, if the preset interval is too large, the effect of the diversion of the colloid flow channel 21 may be influenced, and the preset interval is reserved for 2-5 mm, so that the thickness of the colloid surface on the width direction of the colloid surface is more uniform while the completeness of the colloid surface is ensured.

With continued reference to fig. 1, in some embodiments, the body 10 has a flat tubular shape and includes a top wall 12 and a bottom wall 14 opposite to each other in a thickness direction of the body 10, and a first side wall 11 and a second side wall 13 opposite to each other in a width direction of the body 10, each partition wall 50 is connected to an inner surface of the top wall 12 and an inner surface of the bottom wall 14, and the width direction of the body 10 coincides with the width direction of the glue outlet 40.

The width direction of the body 10 is consistent with the width direction of the glue outlet 40, namely, the first side wall 11 and the second side wall 13 correspond to two opposite sides of the width direction of the glue outlet 40, and the top wall 12 and the bottom wall 14 correspond to two opposite sides of the glue outlet 40 perpendicular to the width direction.

The partition wall 50 may be connected between the inner surface of the top wall 12 and the inner surface of the bottom wall 14 by welding, or may be integrally formed with the body 10, so as to facilitate processing and manufacturing.

The body 10 is flat tubular and the width direction of the body 10 is consistent with the width direction of the glue outlet 40, so that the body 10 has a certain guiding and drainage effect on the glue entering the body 10 through the glue inlet 30, and the glue is guided to spread along the width direction of the glue outlet 40, so that the glue fills the inner cavity 20 of the body 10 along the width direction of the glue outlet 40.

In some embodiments, the glue inlet 30 and the glue outlet 40 are respectively located at two ends of the body 10, and the width of the body 10 gradually increases from the glue inlet 30 to the glue outlet 40.

The thickness of the body 10 may be gradually reduced from the glue inlet 30 to the glue outlet 40, or may be always consistent from the glue inlet 30 to the glue outlet 40.

The body 10 is in a flat tubular shape which is gradually enlarged from the glue inlet 30 to the glue outlet 40, the glue inlet 30 and the glue outlet 40 are respectively positioned at two ends of the body 10, the shape of the body 10 directly generates a diversion effect on the glue entering through the glue inlet 30, so that the glue can be gradually spread along the width direction of the glue outlet 40 in the process of directly flowing to the glue outlet 40, the smoothness of the glue flowing is ensured, and the glue is prevented from stagnating and blocking in the body 10.

In some embodiments, the included angle α between the glue inlet 30 and the plane of the glue outlet 40 is an acute angle.

With continued reference to fig. 3, the included angle α between the glue inlet direction W of the glue inlet 30 and the plane of the glue outlet 40 is an acute angle, i.e. the glue inlet direction W of the glue inlet 30 is not parallel to and not coincident with the axis of the glue outlet 40, and the angle of the included angle α can be set according to the inclination angle of the inclined plane on which the glue is required to be applied. It can be understood that the end of the flat tubular body 10 having the glue inlet 30 is bent by a preset angle compared to the end having the glue outlet 40, and the preset angle is an included angle α between the glue inlet direction W of the glue inlet 30 and the plane of the glue outlet 40.

When the glue outlet device 100 is applied to oblique glue spreading, a certain included angle is necessarily formed between the width direction of the glue outlet 40 and the horizontal plane. At present, in practical application, the glue inlet 30 is generally vertically downwards glue-inlet or obliquely upwards and obliquely downwards glue-inlet, and the glue outlet 40 of the glue outlet device 100 of the application is inclined compared with the glue inlet 30, so that the glue outlet 40 is inclined by a certain angle compared with the horizontal plane for inclined glue-coating on the premise of not changing the direction of the glue inlet 30.

Optionally, the included angle α between the glue inlet direction W of the glue inlet 30 and the plane of the glue outlet 40 is 30 ° to 60 °.

The larger the included angle alpha between the glue inlet direction W of the glue inlet 30 and the plane of the glue outlet 40 is, the larger the bending angle of the flat tubular body 10 is, and the bending angle of the glue flow channel is also increased. The bending angle of the colloid flow channel in the body is too large, so that the smoothness of the flowing of the colloid in the body can be influenced, the included angle between the colloid inlet direction W of the colloid inlet 30 and the plane where the colloid outlet 40 is positioned is 30-60 degrees, the smoothness of the flowing of the colloid in the body 10 can be firmly ensured while the convenience of inclined-plane gluing is effectively ensured, and the performance stability of the whole colloid outlet device is ensured.

Alternatively, referring to fig. 1 and 3 again, the first side wall 11 and the second side wall 13 are arc-shaped walls, the first side wall 11 is curved toward the second side wall 13, the second side wall 13 is curved away from the first side wall 11, and the length of the second side wall 13 is greater than the length of the first side wall 11.

When the glue outlet device 100 is applied to actual inclined surface gluing, a certain included angle is formed between the width direction of the glue outlet 40 and the horizontal plane, and the horizontal height of one end of the glue outlet 40 in the width direction is lower than the other end of the glue outlet 40 in the width direction. The first side wall 11 extends from the glue inlet 30 to an end with a higher horizontal height in the width direction of the glue outlet 40, the second side wall 13 extends from the glue inlet 30 to an end with a lower horizontal height in the width direction of the glue outlet 40, and the length of the second side wall 13 is greater than that of the first side wall 11.

The first side wall 11 and the second side wall 13 are arc-shaped walls, and have a smooth flow guiding effect on the colloid, so that the colloid can flow smoothly, and the colloid is prevented from accumulating in the body 10.

Alternatively, the plurality of partition walls 50 are each arc-shaped walls, and each partition wall 50 is provided curved in a direction toward the second side wall 13. I.e. the plurality of partition walls 50 are bent in the same direction as the first side wall 11 and the second side wall 13.

The plurality of partition walls 50 are contoured to form an arc wall on the first side wall 11 and the second side wall 13, so as to form a plurality of arc-shaped gel flow passages 21 in the same bending direction as the first side wall 11 and the second side wall 13 in the inner chamber 20, so as to ensure that each gel flow passage 21 has a smooth flow guiding effect on the gel, ensure smooth flow of the gel, and further avoid accumulation of the gel in the body 10.

In some embodiments, referring to fig. 3, the plurality of partition walls 50 includes: a plurality of first partition walls 51, the plurality of first partition walls 51 being provided at intervals in the width direction of the body 10; and a plurality of second partition walls 52, each second partition wall 52 being disposed between two adjacent first partition walls 51, one end of the second partition wall 52 adjacent to the glue inlet 30 exceeding one end of the first partition wall 51 adjacent to the glue inlet 30.

Each of the second partition walls 52 is disposed between two adjacent first partition walls 51, i.e., the second partition walls 52 are not adjacent to the first side wall 11 or the second side wall 13, and the number of the second partition walls 52 is one less than the number of the first partition walls 51.

The end of the second partition wall 52 adjacent to the glue inlet 30 exceeds the end of the first partition wall 51 adjacent to the glue inlet 30, i.e. the extension length of the second partition wall 52 in the direction of the glue inlet 30 is greater than the extension length of the first partition wall 51 in the direction of the glue inlet 30.

Optionally, gaps exist between one end, close to the glue inlet 30, of the plurality of second partition walls 52 and the glue inlet 30, so that resistance of the glue at the glue inlet 30 can be effectively reduced, and smoothness of the glue entering the glue inlet 30 is ensured.

The first partition wall 51 and the second partition wall 52 form a grading flow channel in the body 10 to gradually split the colloid, the plurality of second partition walls 52 firstly split the colloid for the first time, and then the first partition wall 51 splits the colloid between two adjacent second partition walls 52 for the second time, so that on one hand, the problems of overlarge resistance and colloid accumulation caused by the fact that the plurality of partition walls 50 split the colloid at the position close to the colloid inlet 30 simultaneously are avoided; on the other hand, the first partition wall 51 and the second partition wall 52 divide the colloid step by step, so that the smoothness of colloid split is further ensured, and the uniformity of colloid split is improved.

In some embodiments, the end of the second partition wall 52 adjacent to the glue outlet 40 is flush with the end of the first partition wall 51 adjacent to the glue outlet 40.

One end of the second partition wall 52 close to the glue outlet 40 is flush with one end of the first partition wall 51 close to the glue outlet 40, i.e. the plane of the tail ends of the glue runners 21 is parallel to the plane of the glue outlet 40.

The thickness of the colloid confluence region 22 in the width direction of the glue outlet 40 is equal by the arrangement, so that the colloid confluence of the colloid confluence region 22 is more balanced.

In some embodiments, in two adjacent gel flow channels 21, the width of the end of the gel flow channel 21 near the second sidewall 13 is smaller than the width of the end of the gel flow channel 21 far from the second sidewall 13.

The "end of the gel flow path 21" refers to the end along the flow direction of the gel in the gel flow path 21, that is, the end of the gel flow path 21 near the gel outlet 40.

Alternatively, the width of the end of each gel flow path 21 is 5 to 10mm.

The terminal of colloid runner 21 is too narrow and easily influences the unobstructed nature of colloid flow, and the terminal of colloid runner 21 is too wide then influences the effect of colloid along evenly reposition of redundant personnel in the width direction of glue outlet 40, and in this application, the width of the terminal of every colloid runner 21 is 5 ~ 10mm, can play the reposition of redundant personnel effect to the colloid when guaranteeing that the colloid flows unobstructed, makes the colloid distribute more evenly in the width direction.

It can be understood that, when the glue is applied on the actual inclined surface, the horizontal height of the end of the glue channel 21 close to the second side wall 13 is lower than the horizontal height of the end of the glue channel 21 far away from the second side wall 13, the glue is affected by gravity, the glue amount of the end of the glue channel 21 close to the second side wall 13 is more, in this application, the width of the end of the glue channel 21 gradually increases from the side close to the second side wall 13 to the side close to the first side wall 11, and then the glue flow rate gradually increases from the side close to the second side wall 13 to the side close to the first side wall 11, so that the glue outlet amount of the glue channel 21 close to the second side wall 13 is smaller than the glue outlet amount of the glue channel 21 far away from the second side wall 13, and the glue outlet amount flowing out of each glue channel 21 is further controlled step by step, so that the glue outlet 40 is more uniform in the width direction.

Alternatively, the linear distance between the end of the second partition wall 52 near the glue inlet 30 and the end near the glue outlet 40 is 65% -80% of the linear distance between the center of the glue outlet 40 and the center of the glue inlet 30.

The linear length between the two ends of the second partition wall 52 is 65% -80% of the linear distance between the center of the glue outlet 40 and the center of the glue inlet 30 of the body 10, and the design makes one end of the second partition wall 52, which is close to the glue inlet 30, not close to the glue inlet 30 nor far away from the glue inlet 30, so that the smoothness of glue flow is ensured, and meanwhile, the glue is split for the first time in time, and the split uniformity is ensured.

Alternatively, the linear distance between the end of the first partition wall 51 near the glue inlet 30 and the end near the glue outlet 40 is 30% -50% of the linear distance between the center of the glue outlet 40 and the center of the glue inlet 30.

The linear length between both ends of the first partition wall 51 is 30% to 50% of the linear distance between the center of the glue outlet 40 and the center of the glue inlet 30 of the body 10, i.e., the first partition wall 51 extends about half the length of the second partition wall 52.

The distance between the both ends of the first partition wall 51 is about half the distance between the both ends of the second partition wall 52, and a stable secondary flow dividing effect is achieved without affecting the primary flow dividing effect of the second partition wall 52.
