[0002] In the related art, the glue in the glue discharging mechanism of the glue coating equipment is discharged through the glue discharging nozzle structure. In different application scenarios of the glue discharging mechanism, the use requirements for the glue discharging flow rate of the glue discharging nozzle structure are different. However, due to the structural limitations of the glue discharging nozzle structure, the glue discharging nozzle structure in the related art is difficult to meet and adapt to the needs of glue coating occasions with different glue discharging flow rates. For example, when the glue discharging flow rate demand is small and the glue discharging flow rate of the glue discharging nozzle structure itself is large, it may cause glue waste and lead to poor glue coating quality, etc.; when the glue discharging flow rate demand is large and the glue discharging flow rate of the glue discharging nozzle structure itself is small, it may lead to low glue coating efficiency and poor glue coating quality due to insufficient glue discharge per unit time, etc. Utility Model Content

[0003] In view of the above problems, the utility model proposes a glue nozzle structure, a glue discharge mechanism and a glue coating device. The glue discharge flow rate of the glue nozzle structure can be adjusted so that the glue discharge flow rate of the glue nozzle structure can meet and adapt to the requirements of glue coating occasions with different glue discharge flow rates. This is conducive to the glue nozzle structure having good glue coating quality and efficiency in different application scenarios.

[0004] In the first aspect, the utility model provides a glue outlet nozzle structure, including: a glue outlet nozzle body, having a glue outlet channel, the glue outlet nozzle body including a plurality of glue outlet walls connected in sequence along the circumference of the glue outlet channel, the plurality of glue outlet walls including two first glue outlet walls arranged opposite to each other along a first direction, at least one of the two first glue outlet walls can move along the first direction.

[0005] In the above technical scheme, by enabling at least one of the two first glue outlet walls to move along the first direction, the distance between the two first glue outlet walls in the first direction can be adjusted, so that the size of the cross section of the glue outlet channel between the multiple glue outlet walls can be adjusted accordingly; by adjusting the size of the cross section of the glue outlet channel, the glue outlet flow rate in the glue outlet nozzle structure can be adjusted, and by adjusting the glue outlet flow rate, the requirements of glue coating occasions with different glue outlet flow rates can be met and adapted, which is also beneficial for the glue outlet nozzle structure to have good glue coating quality and efficiency in different application scenarios.

[0006] In some embodiments, the plurality of said glue outlet walls include two second glue outlet walls arranged opposite to each other along a second direction, wherein the second direction intersects with the first direction, and the two first glue outlet walls are located between the two second glue outlet walls, wherein at least one of the first glue outlet walls is slidably connected to the second glue outlet wall.

[0007] In the above technical solution, by making the two first glue outlet walls located between the two second glue outlet walls, and making at least one of the first glue outlet walls slidably connected to the second glue outlet wall, at least one glue outlet wall can slide relative to the second glue outlet wall when moving along the first direction, thereby preventing the second glue outlet wall from interfering with or hindering the movement of the first glue outlet wall.

[0008] In some embodiments, guide grooves extending along the first direction are formed on both of the second glue outlet walls, and guide protrusions are formed on opposite sides of the first glue outlet wall along the second direction. The guide protrusions are accommodated in the guide grooves and can slide relative to the guide grooves along the first direction.

[0009] In the above technical solution, a guide groove extending along the first direction is formed on the second glue outlet wall, and guide protrusions are formed on the opposite sides of the first glue outlet wall along the second direction, and the guide protrusions are accommodated in the guide grooves and can slide relative to the guide grooves along the first direction. In this way, a connection relationship can be formed between the first glue outlet wall and the second glue outlet wall, and the guide grooves limit and guide the guide protrusions, so that the first glue outlet wall can slide stably relative to the second glue outlet wall along the first direction.

[0010] In some embodiments, there are multiple guide grooves, and the multiple guide grooves are arranged at intervals along a third direction, the third direction, the second direction and the first direction intersect each other, and the third direction is the extension direction of the glue outlet channel. There are multiple guide protrusions, and the multiple guide protrusions correspond one by one to the multiple guide grooves respectively.

[0011] In the above technical solution, by providing a plurality of guide grooves and arranging them at intervals along the third direction, and by cooperating with a plurality of guide grooves and a plurality of guide protrusions, the second guide wall forms a plurality of limiting and guiding functions on the first glue outlet wall in the third direction, so that the first glue outlet wall can slide more stably relative to the second glue outlet wall.

[0012] In some embodiments, in the second direction, a first sealing layer is provided between the first glue outlet wall and the second glue outlet wall, and the first sealing layer is fixed on one of the first glue outlet wall and the second glue outlet wall.

[0013] In the above technical solution, by providing a first sealing layer between the first glue outlet wall and the second glue outlet wall, glue leakage between the first glue outlet wall and the second glue outlet wall can be avoided when at least one of the first glue outlet walls slides relative to the second glue outlet wall, thereby avoiding glue waste and affecting the normal operation of the glue outlet nozzle structure.

[0014] In some embodiments, the glue outlet channel includes a first glue outlet channel, the first glue outlet wall includes a first wall portion, the first wall portions of two first glue outlet walls are arranged opposite to each other along the first direction, the first wall portions constitute a part of the side wall of the first glue outlet channel, and in the glue outlet direction of the glue outlet channel, the distance between the first wall portions of the two first glue outlet walls gradually increases;

[0015] The glue discharge nozzle structure includes a glue discharge valve, which is arranged in the glue discharge channel and can move along a third direction, the third direction intersects with the first direction and is the extension direction of the glue discharge channel, the glue discharge valve has two first valve faces arranged opposite to each other along the first direction, in the glue discharge direction of the glue discharge channel, the distance between the two first valve faces gradually increases, the two first valve faces are respectively arranged corresponding to the first wall portions of the two first glue discharge walls, and when the glue discharge valve is in a position to close the glue discharge channel, the two first valve faces are respectively sealed and matched with the first wall portions of the two first glue discharge walls.

[0016] In the above technical solution, by arranging a glue outlet valve in the glue outlet channel, the glue outlet valve can close or open the glue outlet channel by moving along the third direction. When the glue outlet nozzle structure does not need to discharge glue, the glue outlet valve can close the glue outlet channel, and when the glue outlet nozzle structure needs to discharge glue, the glue outlet valve can open the glue outlet channel. When the glue outlet valve is in the position of closing the glue outlet channel, the sealing cooperation between the first valve surface of the glue outlet valve and the first wall portion of the first glue outlet wall facilitates the glue outlet valve to form a sealing effect on the glue in the glue outlet channel, and forms a good sealing effect on the glue in the glue outlet channel, which can avoid the glue in the glue outlet channel from flowing out from between the first valve surface and the first wall portion and causing glue leakage.

[0017] By gradually increasing the spacing between the first wall portions of the two first glue outlet walls along the glue outlet direction of the glue outlet channel, and by gradually increasing the spacing between the two first valve faces of the glue outlet valve in the glue outlet direction of the glue outlet channel, it is convenient for the two first wall portions to correspond and cooperate with the two first valve faces respectively in the first direction; when at least one first glue outlet wall moves along the first direction, and the spacing between the two first wall portions in the first direction decreases or increases, there is no need to replace the valve to maintain a sealing fit between the first valve face and the first wall portion, and by moving the glue outlet valve along the third direction relative to the glue outlet channel, different positions of the two first valve faces can still maintain a sealing fit with the two first wall portions. In this way, when the first glue outlet wall adjusts the glue outlet flow rate of the glue outlet channel through movement, the first wall portion and the first valve face can always maintain a sealing fit, and the glue outlet valve and the glue outlet channel have a high degree of matching.

[0018] In some embodiments, the longitudinal section of the dispensing valve is a triangle or a trapezoid, and the section obtained by cutting the dispensing valve with a plane perpendicular to the second direction is the longitudinal section of the dispensing valve, and the second direction, the first direction and the third direction intersect each other.

[0019] In the above technical scheme, by making the longitudinal section of the glue discharge valve triangular or trapezoidal, the structure of the glue discharge valve is regular and simple, so that the glue discharge valve is easy to form; in addition, when the glue discharge nozzle structure discharges glue, the glue in the glue discharge channel pushes the glue discharge valve to move relative to the glue discharge channel along the third direction, so that the longitudinal section of the glue discharge valve is triangular or trapezoidal, and the glue in the glue discharge channel can be diverted along the two sides of the triangle or trapezoid, so that the mutual force between the glue in the glue discharge channel and the glue discharge valve is reduced, which is beneficial to reduce the wear of the glue discharge valve.

[0020] In some embodiments, the longitudinal section of the glue discharging valve is an isosceles triangle or an isosceles trapezoid.

[0021] In the above technical solution, by making the longitudinal section of the glue discharge valve an isosceles triangle or an isosceles trapezoid, the extension lengths of the surfaces of the two waists of the glue discharge valve along the isosceles triangle or the isosceles trapezoid are the same, and the extension lengths of the two first valve surfaces of the glue discharge valve opposite to each other along the first direction are the same, so that the sealing cooperation effect between the two first valve surfaces and the two correspondingly arranged first wall portions is always the same, avoiding the problem of poor unilateral sealing effect in the first direction.

[0022] In some embodiments, the plurality of glue outlet walls include two second glue outlet walls disposed opposite to each other along the second direction, the second glue outlet walls include a second wall portion, the second wall portions of the two second glue outlet walls are disposed opposite to each other along the second direction, and the second wall portion constitutes a partial side wall of the first glue outlet channel;

[0023] The glue outlet valve has two second valve faces arranged opposite to each other along the second direction. When the glue outlet valve is in a position to close the glue outlet channel, the two second valve faces are respectively sealed with the second wall portions of the two second glue outlet walls, and the two second valve faces are arranged in parallel.

[0024] In the above technical solution, by making the multiple glue outlet walls include two second glue outlet walls arranged oppositely along the second direction, and making the glue outlet valve have two second valve faces arranged oppositely along the second direction, it is convenient for the two second wall parts of the second glue outlet wall to respectively correspond with the two second valve faces of the glue outlet valve in the second direction; when the glue outlet valve is in the position of closing the glue outlet channel, the sealing cooperation between the two second valve faces and the two second wall parts facilitates the glue outlet valve to form a sealing effect on the glue in the glue outlet channel, and forms a good sealing effect on the glue in the glue outlet channel, which can avoid the glue in the glue outlet channel from flowing out between the second valve face and the second wall part and causing glue leakage. By making the two second valve faces arranged in parallel, the structure of the glue outlet valve is more regular and simple, and the glue outlet valve is easier to form; in addition, when at least one first glue outlet wall moves along the first direction, the glue outlet valve maintains the sealing cooperation effect between the first valve face and the first wall part by moving relative to the glue outlet channel along the third direction, and the two parallel second valve faces are conducive to the second valve face and the second wall part always maintaining a good sealing cooperation.

[0025] In some embodiments, a cross section of the first glue outlet channel and a cross section of the glue outlet valve are both rectangular.

[0026] In the above technical solution, by making the cross section of the first glue outlet channel and the cross section of the glue outlet valve both rectangular, it is beneficial for the glue outlet valve to cooperate well with the first glue outlet channel, so that when the glue outlet valve is in the position of closing the glue outlet channel, the glue outlet valve has a good sealing effect on the glue outlet channel; when the glue outlet valve moves along the third direction relative to the glue outlet channel to open or close the glue outlet channel, the first glue outlet channel can guide the glue outlet valve in the third direction, so that the glue outlet valve can accurately open and close the glue outlet channel. In addition, by making the cross section of the first glue outlet channel rectangular, the first glue outlet wall portion forming the first glue outlet channel can adjust the glue outlet flow rate in the first glue outlet channel more uniformly when it moves along the first direction.

[0027] In some embodiments, the glue outlet channel includes a second glue outlet channel, and the second glue outlet channel and the first glue outlet channel are arranged in sequence along the glue outlet direction; the cross section of the second glue outlet channel remains unchanged in the second direction.

[0028] In the above technical solution, by keeping the cross-section of the second glue outlet channel unchanged, the spacing between the two first glue outlet walls of the second glue outlet channel in the glue outlet direction is consistent, and the spacing between the two second glue outlet walls in the glue outlet direction is also consistent, so that the glue in the second glue outlet channel is evenly distributed and easy to flow; when the glue outlet channel is adjusted by moving at least one first glue outlet wall along the first direction, the various parts of the second glue outlet channel change consistently, and the adjustment effect on the glue outlet flow rate in the second glue outlet channel is also relatively uniform.

[0029] In some embodiments, the glue outlet channel includes a second glue outlet channel, and the second glue outlet channel and the first glue outlet channel are arranged in sequence along the glue outlet direction; the cross-section of the second glue outlet channel is rectangular.

[0030] In the above technical solution, by making the cross section of the second glue outlet channel rectangular, the first glue outlet wall portion forming the second glue outlet channel can regulate the glue outlet flow rate in the second glue outlet channel more evenly when moving along the first direction.

[0031] In the second aspect, the utility model provides a glue discharging mechanism, comprising: a cylinder body, the cylinder body having a accommodating chamber and a glue outlet and a glue inlet suitable for being connected to the accommodating chamber, the accommodating chamber being used to accommodate glue; a glue discharging nozzle structure, the glue discharging nozzle structure is the glue discharging nozzle structure of the first aspect of the utility model, the glue discharging nozzle body is arranged at the glue outlet, and the first glue discharging wall is movably connected to the cylinder body; a glue pushing member, the glue pushing member comprises a piston and a push rod, the piston is reciprocatingly arranged in the accommodating chamber, and one end of the push rod is connected to the piston to drive the piston to move.

[0033] In some embodiments, a limiting flange is formed at one end of the first glue outlet wall adjacent to the glue outlet, and a limiting step surface is formed on the inner wall of the cylinder body. The limiting flange is sealed with the limiting step surface and can move relative to the cylinder body along the first direction.

[0034] In the above technical solution, a limiting flange that can move relative to the cylinder body along a first direction is formed at one end of the first glue outlet wall adjacent to the glue outlet, and a limiting step surface is formed on the inner wall of the cylinder body. When at least one glue outlet wall moves along the first direction, the sealing cooperation between the limiting flange and the limiting step surface can prevent the glue in the cylinder body from flowing out of the gap between the first glue outlet wall and the cylinder body.

[0035] In some embodiments, a second sealing layer is provided between the limiting flange and the inner wall of the cylinder body, and the second sealing layer is fixed to one of the limiting flange and the cylinder body.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0066] With the widespread application of glue coating technology, the application scenarios of glue coating equipment are increasing. In different application scenarios, the requirements for the glue coating quality and glue coating efficiency of glue coating equipment are also getting higher and higher. Glue coating equipment usually includes a glue dispensing mechanism for dispensing glue, and the glue is dispensed through the glue dispensing nozzle structure of the glue dispensing mechanism.

[0067] In the related art, the glue in the glue discharging mechanism of the glue coating equipment is discharged through the glue discharging nozzle structure. In different application scenarios of the glue discharging mechanism, the use requirements for the glue discharging flow rate of the glue discharging nozzle structure are different. However, due to the structural limitations of the glue discharging nozzle structure, the glue discharging nozzle structure in the related art is difficult to meet and adapt to the needs of glue coating occasions with different glue discharging flow rates. For example, when the glue discharging flow rate demand is small and the glue discharging flow rate of the glue discharging nozzle structure itself is large, it may cause glue waste and lead to poor glue coating quality, etc.; when the glue discharging flow rate demand is large and the glue discharging flow rate of the glue discharging nozzle structure itself is small, it may lead to low glue coating efficiency and poor glue coating quality due to insufficient glue discharge per unit time, etc.

[0068] In the embodiment of the present utility model, the glue discharge flow rate refers to the glue discharge amount per unit time.

[0069] Based on this, the applicant proposed a glue outlet nozzle structure, which includes a glue outlet nozzle body having a glue outlet channel, and the glue outlet nozzle body also includes a plurality of glue outlet walls connected in sequence along the circumference of the glue outlet channel, wherein the plurality of glue outlet walls include two first glue outlet walls arranged opposite to each other along a first direction, and at least one of the two first glue outlet walls can move along the first direction.

[0070] In such a glue outlet nozzle structure, the multiple glue outlet walls of the glue outlet nozzle body that are sequentially connected along the circumference of the glue outlet channel include two first glue outlet walls that are relatively arranged along a first direction. By enabling at least one of the two first glue outlet walls to move along the first direction, the distance between the two first glue outlet walls in the first direction can be adjusted, so that the size of the cross-section of the glue outlet channel between the multiple glue outlet walls can be adjusted accordingly; the glue outlet flow rate in the glue outlet nozzle structure can be adjusted by adjusting the size of the cross-section of the glue outlet channel, and the glue outlet nozzle structure can meet and adapt to the requirements of glue coating occasions with different glue outlet flow rates by adjusting the glue outlet flow rate. This is also beneficial for the glue outlet nozzle structure to have good glue coating quality and efficiency in different application scenarios.

[0071] The glue nozzle structure of the utility model can be widely used in many production fields, such as batteries, electronic equipment, automobiles, medical equipment and other fields, and the embodiments of the utility model are not limited to this. For example, the glue nozzle structure disclosed in the utility model can be applied to the battery field, and can involve battery cells, battery monomers, battery boxes, etc. in the battery field without limitation.

[0072] For example, the glue nozzle structure of the utility model can be used to apply glue to the battery cell, so that the inside of the battery cell becomes a sealed environment. The glue nozzle structure of the utility model can also be used to apply glue to multiple battery cells to connect the multiple battery cells. The multiple battery cells are bonded into a whole through the glue discharged by the glue nozzle structure, which can be used to improve the collision safety of the battery cell. The glue nozzle structure of the utility model can also be used to bond the battery cell to the box body. The glue can increase the structural strength of the battery box, and the glue connected between the battery cell and the box body can also be used as a heat conductive medium. The glue layer plays a heat conductive role and is used to transfer the heat generated by the battery cell to the box body, and further transfer it to the water cooling system through the box body, so that the battery box can dissipate heat.

[0073] Reference below Figure 1-Figure 6 A glue nozzle structure 100 according to an embodiment of the present invention is described.

[0074] refer to Figure 1-Figure 4 In the first aspect, the utility model provides a glue outlet structure 100, including a glue outlet nozzle body 1, the glue outlet nozzle body 1 has a glue outlet channel 11, the glue outlet nozzle body 1 includes a plurality of glue outlet walls 12 connected in sequence along the circumference of the glue outlet channel 11, the plurality of glue outlet walls 12 include two first glue outlet walls 121 arranged opposite to each other along a first direction, and at least one of the two first glue outlet walls 121 can move along the first direction.

[0075] Wherein, the first direction can refer to the direction e1 in the figure. When the glue nozzle structure 100 is required to have a larger glue discharge flow rate, at least one of the two first glue discharge walls 121 can be moved along the first direction to increase the distance between the two first glue discharge walls 121 in the first direction, thereby increasing the size of the cross section of the glue discharge channel 11, increasing the flow area of ​​the glue discharge channel 11, and increasing the glue discharge flow rate of the glue nozzle structure 100. When the glue nozzle structure 100 is required to have a smaller glue discharge flow rate, at least one of the two first glue discharge walls 121 can be moved along the first direction to reduce the distance between the two first glue discharge walls 121 in the first direction, thereby reducing the size of the cross section of the glue discharge channel 11, reducing the flow area of ​​the glue discharge channel 11, and reducing the glue discharge flow rate of the glue nozzle structure 100. Wherein, the first direction can refer to the direction e1 in the figure.

[0076] When the cross-sectional size of the glue outlet channel 11 is constant, the flow area of ​​the glue outlet channel 11 is constant, and the glue outlet flow rate can be increased by increasing the glue outlet pressure. However, the adjustable range of the glue outlet pressure is limited, so the regulating effect on the glue outlet flow rate is limited. Increasing the glue outlet pressure places higher pressure requirements on the equipment, and excessive glue outlet pressure will also have an adverse effect on the workpiece being coated with glue.

[0077] Optionally, one of the two first glue outlet walls 121 may move along the first direction. For example, one of the first glue outlet walls 121 moves along the first direction toward the direction close to the other first glue outlet wall 121, and the distance between the two first glue outlet walls 121 in the first direction is reduced; for example, one of the first glue outlet walls 121 moves along the first direction toward the direction away from the other first glue outlet wall 121, and the distance between the two first glue outlet walls 121 in the first direction is increased.

[0078] Optionally, both first glue outlet walls 121 can move along the first direction. For example, the two first glue outlet walls 121 move toward each other along the first direction, and the distance between the two first glue outlet walls 121 decreases in the first direction; for example, the two first glue outlet walls 121 move away from each other along the first direction, and the distance between the two first glue outlet walls 121 increases in the first direction.

[0079] In the above technical scheme, by enabling at least one of the two first glue outlet walls 121 to move along the first direction, the distance between the two first glue outlet walls 121 in the first direction can be adjusted, so that the size of the cross section of the glue outlet channel 11 between the multiple glue outlet walls 12 can be adjusted accordingly; by adjusting the size of the cross section of the glue outlet channel 11, the glue outlet flow rate in the glue outlet nozzle structure 100 can be adjusted, and by adjusting the glue outlet flow rate, the glue outlet nozzle structure 100 can meet and adapt to the requirements of glue coating occasions with different glue outlet flow rates, which is also beneficial for the glue outlet nozzle structure 100 to have good glue coating quality and efficiency in different application scenarios.

[0080] refer to Figure 5 In some embodiments, the plurality of glue outlet walls 12 include two second glue outlet walls 122 arranged opposite to each other along a second direction, the second direction intersects with the first direction, the two first glue outlet walls 121 are located between the two second glue outlet walls 122, and at least one of the first glue outlet walls 121 is slidably connected to the second glue outlet wall 122.

[0081] The second direction may refer to the direction e2 in the figure.

[0082] Optionally, one of the first glue outlet walls 121 is slidably connected to the second glue outlet wall 122 , and the first glue outlet wall 121 can slide relative to the second glue outlet wall 122 along the first direction.

[0083] Optionally, the two first glue outlet walls 121 are slidably connected to the second glue outlet wall 122 , and the two first glue outlet walls 121 can slide relative to the second glue outlet wall 122 along the first direction.

[0084] In the above technical solution, by making the two first glue outlet walls 121 located between the two second glue outlet walls 122, and making at least one of the first glue outlet walls 121 slidably connected to the second glue outlet wall 122, at least one glue outlet wall 12 can slide relative to the second glue outlet wall 122 when moving along the first direction, thereby preventing the second glue outlet wall 122 from interfering with or hindering the movement of the first glue outlet wall 121.

[0085] refer to Figure 6 In some embodiments, guide grooves 1222 extending along the first direction are formed on the two second glue outlet walls 122, and guide protrusions 1213 are formed on the opposite sides of the first glue outlet wall 121 along the second direction. The guide protrusions 1213 are accommodated in the guide grooves 1222 and can slide relative to the guide grooves 1222 along the first direction.

[0086] Optionally, one of the first glue outlet walls 121 is formed with guide protrusions 1213 on two opposite sides along the second direction, and the first glue outlet wall 121 can move along the guide groove 1222 in the first direction relative to the second glue outlet wall 122 .

[0087] Optionally, guide protrusions 1213 are formed on opposite sides of the two first glue outlet walls 121 along the second direction, and the two first glue outlet walls 121 can move relative to the second glue outlet wall 122 in the first direction along the guide groove 1222 .

[0088] In the above technical solution, a guide groove 1222 extending along the first direction is formed on the second glue outlet wall 122, and a guide protrusion 1213 is formed on the opposite sides of the first glue outlet wall 121 along the second direction, and the guide protrusion 1213 is accommodated in the guide groove 1222 and can slide relative to the guide groove 1222 along the first direction, so that a connection relationship can be formed between the first glue outlet wall 121 and the second glue outlet wall 122, and the guide groove 1222 forms a limiting and guiding function for the guide protrusion 1213, so that the first glue outlet wall 121 can stably slide relative to the second glue outlet wall 122 along the first direction.

[0089] In some embodiments, there are multiple guide grooves 1222, and the multiple guide grooves 1222 are arranged at intervals along the third direction. The third direction, the second direction and the first direction intersect each other, and the third direction is the extension direction of the glue outlet channel 11. There are multiple guide protrusions 1213, and the multiple guide protrusions 1213 correspond one by one to the multiple guide grooves 1222 respectively.

[0090] Among them, the third direction can refer to the direction e3 in the figure.

[0091] In the above technical solution, by providing a plurality of guide grooves 1222 and arranging them at intervals along the third direction, and by cooperating with a plurality of guide grooves 1222 and a plurality of guide protrusions 1213, the second guide wall forms a plurality of limiting and guiding functions on the first glue outlet wall 121 in the third direction, so that the first glue outlet wall 121 can slide more stably relative to the second glue outlet wall 122.

[0092] In some embodiments, in the second direction, a first sealing layer is disposed between the first glue outlet wall 121 and the second glue outlet wall 122 , and the first sealing layer is fixed on one of the first glue outlet wall 121 and the second glue outlet wall 122 .

[0093] For example, the first sealing layer is fixed to the first adhesive outlet wall 121 ; or, the first sealing layer is fixed to the second adhesive outlet wall 122 .

[0094] In the above technical solution, by providing a first sealing layer between the first glue outlet wall 121 and the second glue outlet wall 122, glue leakage between the first glue outlet wall 121 and the second glue outlet wall 122 can be avoided when at least one of the first glue outlet walls 121 slides relative to the second glue outlet wall 122, thereby avoiding glue waste and affecting the normal operation of the glue outlet nozzle structure 100.

[0095] refer to Figure 3-Figure 4 In some embodiments, the glue outlet channel 11 includes a first glue outlet channel 111, the first glue outlet wall 121 includes a first wall portion 1211, the first wall portions 1211 of the two first glue outlet walls 121 are arranged opposite to each other along a first direction, and the first wall portion 1211 constitutes a partial side wall of the first glue outlet channel 111. In the glue outlet direction of the glue outlet channel 11, the distance between the first wall portions 1211 of the two first glue outlet walls 121 gradually increases.

[0096] The glue discharge nozzle structure 100 includes a glue discharge valve 2, which is arranged in the glue discharge channel 11 and can move along a third direction, the third direction intersects with the first direction and is the extension direction of the glue discharge channel 11, the glue discharge valve 2 has two first valve faces 21 arranged opposite to each other along the first direction, in the glue discharge direction of the glue discharge channel 11, the distance between the two first valve faces 21 gradually increases, the two first valve faces 21 and the first wall portions 1211 of the two first glue discharge walls 121 are respectively arranged correspondingly, when the glue discharge valve 2 is in the position of closing the glue discharge channel 11, the two first valve faces 21 are respectively sealed with the first wall portions 1211 of the two first glue discharge walls 121.

[0097] Among them, the glue in the glue outlet channel 11 flows out through one end of the first glue outlet channel 111 along the extension direction of the glue outlet channel 11, and the glue outlet direction of the glue outlet channel 11 conforms to the extension direction of the glue outlet channel 11, and is the direction in which the glue in the glue outlet channel 11 flows out of the glue outlet channel 11. The glue outlet direction can be referred to as shown in the direction e4 in the figure.

[0098] For example, when the glue nozzle structure 100 needs to discharge glue, the glue in the glue discharge channel 11 pushes the glue discharge valve 2 to move in the third direction along the glue discharge direction to open the glue discharge channel 11; when the glue nozzle structure 100 does not need to discharge glue, the glue discharge valve 2 moves in the third direction in the direction opposite to the glue discharge direction to close the glue discharge channel 11.

[0099] For example, at least one of the two first glue outlet walls 121 moves along the first direction, the distance between the two first glue outlet walls 121 in the first direction increases, the spacing between the two first wall portions 1211 of the two first glue outlet walls 121 increases, and the glue outlet valve 2 moves in the third direction in the direction opposite to the glue outlet direction, and the positions where the two first valve faces 21 have a larger spacing cooperate with the two first wall portions 1211, so that the two first valve faces 21 and the two first wall portions 1211 can still maintain a sealed fit; when at least one of the two first glue outlet walls 121 moves along the first direction, so that the distance between the two first glue outlet walls 121 in the first direction is reduced, the spacing between the two wall portions of the two first glue outlet walls 121 is reduced, and in order to ensure that the two first valve faces 21 and the two first glue outlet walls 121 can maintain a sealed fit, the glue outlet valve 2 moves in the glue outlet direction in the third direction.

[0100] Optionally, an elastic reset component 23 is further provided at one end of the glue discharge valve 2 away from the glue discharge channel 11 in the third direction. When the glue discharge nozzle structure 100 discharges glue, the glue discharge valve 2 moves in the third direction along the glue discharge direction of the glue discharge channel 11 under the glue discharge pressure, the glue discharge valve 2 opens the glue discharge channel 11, and the elastic reset component 23 is compressed along the third direction; when the glue discharge nozzle structure 100 does not discharge glue, the elastic reset component 23 drives the glue discharge valve 2 to move and reset to the position of closing the glue discharge channel 11 through elastic force.

[0101] In the above technical solution, by arranging the glue outlet valve 2 in the glue outlet channel 11, the glue outlet valve 2 can close or open the glue outlet channel 11 by moving along the third direction. When the glue outlet nozzle structure 100 does not need to discharge glue, the glue outlet valve 2 can close the glue outlet channel 11, and when the glue outlet nozzle structure 100 needs to discharge glue, the glue outlet valve 2 can open the glue outlet channel 11. When the glue outlet valve 2 is in the position of closing the glue outlet channel 11, the sealing cooperation between the first valve face 21 of the glue outlet valve 2 and the first wall portion 1211 of the first glue outlet wall 121 facilitates the glue outlet valve 2 to form a sealing effect on the glue in the glue outlet channel 11, and forms a good sealing effect on the glue in the glue outlet channel 11, which can avoid the glue in the glue outlet channel 11 from flowing out from between the first valve face 21 and the first wall portion 1211 and causing glue leakage.

[0102] By gradually increasing the distance between the first wall portions 1211 of the two first glue outlet walls 121 along the glue outlet direction of the glue outlet channel 11, and gradually increasing the distance between the two first valve faces 21 of the glue outlet valve 2 in the glue outlet direction of the glue outlet channel 11, it is convenient for the two first wall portions 1211 to respectively correspond with the two first valve faces 21 in the first direction; when at least one first glue outlet wall 121 moves along the first direction, the distance between the two first wall portions 1211 in the first direction decreases or increases, and the cross-section of the glue outlet channel 11 changes, there is no need to replace the glue outlet valve separately, nor is there a need to change the structure and shape of the glue outlet valve 2, and the first valve face 21 of the glue outlet valve 2 and the first wall portion 1211 can still maintain a sealed fit, and the function of opening and closing the glue outlet channel 11 can still be achieved. By moving the glue discharge valve 2 along the third direction relative to the glue discharge channel 11, the different positions of the two first valve faces 21 can still maintain a sealing fit with the two first wall portions 1211. In this way, when the first glue discharge wall 121 adjusts the glue discharge flow rate of the glue discharge channel 11 by movement, the first wall portion 1211 and the first valve face 21 can always maintain a sealing fit. The glue discharge valve 2 and the glue discharge channel 11 have a high degree of matching, and the glue discharge valve 2 has a strong applicability.

[0103] refer to Figure 3In some embodiments, the longitudinal section of the glue dispensing valve 2 is a triangle or a trapezoid, and the section obtained by cutting the glue dispensing valve 2 with a plane perpendicular to the second direction is the longitudinal section of the glue dispensing valve 2. The second direction, the first direction, and the third direction intersect with each other.

[0104] In the above technical solution, by making the longitudinal section of the glue discharge valve 2 triangular or trapezoidal, the structure of the glue discharge valve 2 is regular and simple, so that the glue discharge valve 2 is easy to form; in addition, when the glue discharge nozzle structure 100 discharges glue, the glue in the glue discharge channel 11 pushes the glue discharge valve 2 to move relative to the glue discharge channel 11 along the third direction, so that the longitudinal section of the glue discharge valve 2 is triangular or trapezoidal, and the glue in the glue discharge channel 11 can be diverted along the two sides of the triangle or trapezoid, so that the mutual force between the glue in the glue discharge channel 11 and the glue discharge valve 2 is reduced, which is beneficial to reduce the wear of the glue discharge valve 2.

[0105] refer to Figure 3 In some embodiments, the longitudinal section of the glue discharging valve 2 is an isosceles triangle or an isosceles trapezoid.

[0106] In the above technical solution, by making the longitudinal section of the glue discharge valve 2 an isosceles triangle or an isosceles trapezoid, the extension lengths of the surfaces of the glue discharge valve 2 extending along the two waists of the isosceles triangle or the isosceles trapezoid are the same, and the extension lengths of the two first valve faces 21 of the glue discharge valve 2 opposite to each other along the first direction are the same, so that the sealing cooperation effect between the two first valve faces 21 and the two correspondingly arranged first wall portions 1211 is always the same, avoiding the problem of poor unilateral sealing effect in the first direction.

[0107] In some embodiments, the plurality of glue outlet walls 12 include two second glue outlet walls 122 disposed opposite to each other along the second direction, the second glue outlet wall 122 includes a second wall portion 1221, the second wall portions 1221 of the two second glue outlet walls 122 are disposed opposite to each other along the second direction, and the second wall portion 1221 constitutes a partial side wall of the first glue outlet channel 111. The glue outlet valve 2 has two second valve faces 22 disposed opposite to each other along the second direction, and when the glue outlet valve 2 is in a position to close the glue outlet channel 11, the two second valve faces 22 are respectively sealed with the second wall portions 1221 of the two second glue outlet walls 122, and the two second valve faces 22 are disposed in parallel.

[0108] In the above technical scheme, by making the multiple glue outlet walls 12 include two second glue outlet walls 122 arranged opposite to each other along the second direction, and making the glue outlet valve 2 have two second valve faces 22 arranged opposite to each other along the second direction, it is convenient for the two second wall portions 1221 of the second glue outlet wall 122 to respectively correspond with the two second valve faces 22 of the glue outlet valve 2 in the second direction; when the glue outlet valve 2 is in the position of closing the glue outlet channel 11, the sealing cooperation between the two second valve faces 22 and the two second wall portions 1221 facilitates the glue outlet valve 2 to form a sealing effect on the glue in the glue outlet channel 11, and forms a good sealing effect on the glue in the glue outlet channel 11, which can avoid the glue in the glue outlet channel 11 from flowing out from between the second valve face 22 and the second wall portion 1221 and causing glue leakage. By arranging the two second valve faces 22 in parallel, the structure of the glue discharge valve 2 becomes more regular and simple, and the glue discharge valve 2 becomes easier to form; in addition, when at least one first glue discharge wall 121 moves along the first direction, the glue discharge valve 2 maintains the sealing effect between the first valve face 21 and the first wall portion 1211 by moving along the third direction relative to the glue discharge channel 11, the two parallel second valve faces 22 are beneficial for the second valve face 22 and the second wall portion 1221 to always maintain a good sealing effect.

[0109] In some embodiments, the cross-section of the first glue outlet channel 111 and the cross-section of the glue outlet valve 2 are both rectangular.

[0110] In the above technical solution, by making the cross section of the first glue outlet channel 111 and the cross section of the glue outlet valve 2 both rectangular, it is conducive to good cooperation between the glue outlet valve 2 and the first glue outlet channel 111, so that when the glue outlet valve 2 is in the position of closing the glue outlet channel 11, the glue outlet valve 2 has a good sealing effect on the glue outlet channel 11; when the glue outlet valve 2 moves along the third direction relative to the glue outlet channel 11 to open or close the glue outlet channel 11, the first glue outlet channel 111 can guide the glue outlet valve 2 in the third direction, so that the glue outlet valve 2 can accurately open and close the glue outlet channel 11. In addition, by making the cross section of the first glue outlet channel 111 rectangular, when the first glue outlet wall 121 forming the first glue outlet channel 111 moves along the first direction, the effect of regulating the glue outlet flow in the first glue outlet channel 111 is relatively uniform.

[0111] In some embodiments, the glue outlet channel 11 includes a second glue outlet channel 112 , and the second glue outlet channel 112 and the first glue outlet channel 111 are arranged in sequence along the glue outlet direction, and the cross section of the second glue outlet channel 112 remains unchanged in the second direction.

[0112] For example, the glue in the glue outlet nozzle body 1 flows from the second glue outlet channel 112 to the first glue outlet channel 111 , and then flows out from the first glue outlet channel 111 .

[0113] In the above technical scheme, by keeping the cross-section of the second glue outlet channel 112 unchanged, the spacing between the two first glue outlet walls 121 of the second glue outlet channel 112 in the glue outlet direction is consistent, and the spacing between the two second glue outlet walls 122 in the glue outlet direction is also consistent, so that the glue in the second glue outlet channel 112 is evenly distributed and easy to flow; when the glue outlet channel 11 is adjusted by moving at least one first glue outlet wall 121 along the first direction, the various parts of the second glue outlet channel 112 change consistently, and the adjustment effect on the glue outlet flow rate in the second glue outlet channel 112 is also relatively uniform.

[0114] In some embodiments, the glue outlet channel 11 includes a second glue outlet channel 112 , the second glue outlet channel 112 and the first glue outlet channel 111 are arranged in sequence along the glue outlet direction, and the cross section of the second glue outlet channel 112 is rectangular.

[0115] In the above technical solution, by making the cross section of the second glue outlet channel 112 rectangular, the first glue outlet wall 121 forming the second glue outlet channel 112 can regulate the glue outlet flow rate in the second glue outlet channel 112 more uniformly when moving along the first direction.

[0116] refer to Figure 1 In the second aspect, the utility model provides a glue discharging mechanism 200, comprising: a cylinder body 10, the above-mentioned glue discharging nozzle structure 100 and a glue pushing member 20, the cylinder body 10 has a accommodating chamber 101 and a glue outlet 102 and a glue inlet 103 suitable for communicating with the accommodating chamber 101, the accommodating chamber 101 is used to accommodate glue; the glue discharging nozzle body 1 of the glue discharging nozzle structure 100 is arranged at the glue outlet 102, and the first glue discharging wall 121 is movably connected to the cylinder body 10; the glue pushing member 20 comprises a piston 201 and a push rod 202, the piston 201 is reciprocatingly arranged in the accommodating chamber 101, and one end of the push rod 202 is connected to the piston 201 to drive the piston 201 to move.

[0117] The glue discharging mechanism 200 receives glue supplied from an external glue supply mechanism through the glue inlet 103 , and the glue in the accommodating cavity 101 of the cylinder body 10 of the glue discharging structure flows to the glue discharging nozzle structure 100 through the glue outlet 102 and flows out through the glue discharging nozzle structure 100 .

[0118] For example, the glue discharging process of the glue discharging mechanism 200 is as follows: the push rod 202 of the glue pushing member 20 receives the force, the push rod 202 drives the piston 201 to move relative to the cylinder body 10, and the piston 201 pushes the glue in the accommodating chamber 101 of the cylinder body 10 to move toward the glue outlet 102; then, the glue flows to the glue outlet structure 100 through the glue outlet 102, and the glue entering the glue outlet channel 11 pushes the glue outlet valve 2 to move to open the glue outlet channel 11, thereby allowing the glue in the glue outlet channel 11 to flow out.

[0119] In the above technical scheme, by making the glue discharge mechanism 200 include the above-mentioned glue discharge nozzle structure 100, at least one of the two first glue discharge walls 121 of the glue discharge nozzle structure 100 can move along the first direction, so that the glue discharge flow rate of the glue discharge nozzle structure 100 can be adjusted, which makes it possible to adjust the glue discharge flow rate of the glue discharge mechanism 200, so that the glue discharge flow rate of the glue discharge mechanism 200 can meet and adapt to the requirements of glue coating occasions with different glue discharge flow rates, and is also beneficial for the glue discharge mechanism 200 to have good glue coating quality and efficiency in different application scenarios.

The limiting flange 1212 is sealed with the limiting step surface and can move relative to the cylinder body 10 along the first direction.

[0121] In the above technical solution, a limiting flange 1212 that can move along the first direction relative to the cylinder body 10 is formed at one end of the first glue outlet wall 121 adjacent to the glue outlet 102, and a limiting step surface is formed on the inner wall of the cylinder body 10. When at least one glue outlet wall 12 moves along the first direction, the sealing cooperation between the limiting flange 1212 and the limiting step surface can prevent the glue in the cylinder body 10 from flowing out of the gap between the first glue outlet wall 121 and the cylinder body 10.

[0122] In some embodiments, a second sealing layer is provided between the limiting flange 1212 and the inner wall of the cylinder body 10 , and the second sealing layer is fixed to one of the limiting flange 1212 and the cylinder body 10 .

[0123] In the above technical solution, by providing a second sealing layer between the limiting flange 1212 and the inner wall of the cylinder body 10, the second sealing layer can prevent the glue in the cylinder body 10 from flowing out from between the limiting flange 1212 and the cylinder body 10, which is beneficial to improving the sealing effect between the limiting flange 1212 and the cylinder body 10.

[0124] In some embodiments, the glue discharging mechanism 200 includes a driving component, which is disposed outside the cylinder body 10. The cylinder body 10 is provided with an avoidance hole 104. The driving end of the driving component is passed through the avoidance hole 104 and connected to the first glue discharging wall 121 to drive the first glue discharging wall 121 to move.

[0125] Optionally, the driving component can be operated manually, for example, the driving component can be pressed manually so that the driving end of the driving component drives the first glue outlet wall 121 to move.

[0126] Optionally, the driving assembly may be controlled by a mechanical device, for example, a pneumatic device, so that the driving end of the driving assembly drives the first glue outlet wall 121 to move.

[0127] Optionally, the glue outlet structure includes two driving components, the two driving components are arranged opposite to each other along the first direction, and two avoidance holes 104 are formed on the cylinder body 10 and are arranged opposite to each other along the first direction. The driving ends of the two driving components are correspondingly penetrated through the two avoidance holes 104 and are respectively connected to the two first glue outlet walls 121.

[0128] In the above technical solution, by providing the avoidance hole 104 on the cylinder body 10, the driving assembly can be conveniently connected to the first glue outlet wall 121 through the avoidance hole 104. By providing the driving assembly, the driving end of the driving assembly passes through the avoidance hole 104 on the cylinder body 10 and is connected to the first glue outlet wall 121, so that the driving assembly can conveniently drive the first glue outlet wall 121 to move.

[0129] In some embodiments, the glue outlet mechanism 200 also includes a locking structure, which is used to lock the movable first glue outlet wall 121 in a preset position; the locking structure includes a locking member and a locking hole formed on the outer wall surface of the first glue outlet wall 121, and the locking member is movably arranged on the cylinder body 10 to be inserted into or disengaged from the locking hole.

[0130] For example, the locking member is disengaged from the locking hole, and the driving assembly drives the first glue outlet wall 121 to move along the first direction. After the first glue outlet wall 121 moves to the preset position, the locking member is inserted into the locking hole to lock the first glue outlet wall 121 at the preset position.

[0131] In the above technical solution, by setting a locking structure, the locking structure enables the first glue outlet wall 121 to be stably maintained at a preset position, so that the distance between the two first glue outlet walls 121 in the first direction can be stably maintained, so that the glue outlet flow rate in the glue outlet channel 11 can be stably maintained at a certain state. By making the locking structure include a locking member and a locking hole, the locking member is inserted into the locking hole by movement, so that the first glue outlet wall 121 is locked at the preset position, and the locking member is disengaged from the locking hole by movement, so that the first glue outlet wall 121 can move along the first direction to adjust the glue outlet flow rate of the glue outlet channel 11; the cooperation between the locking member and the locking hole makes it easy to control whether the first glue outlet wall 121 can move along the first direction.

[0134] Next, we will refer to Figure 1-Figure 6 The glue discharging mechanism 200 of some embodiments of the present invention is described.

[0135] Reference Figure 1-Figure 6 In this embodiment, the glue discharging mechanism 200 includes: a cylinder body 10, the above-mentioned glue discharging nozzle structure 100 and a glue pushing member 20. The cylinder body 10 has a accommodating chamber 101 and a glue outlet 102 and a glue inlet 103 suitable for communicating with the accommodating chamber 101. The accommodating chamber 101 is used to accommodate glue. The glue discharging nozzle body 1 of the glue discharging nozzle structure 100 is arranged at the glue outlet 102. The first glue discharging wall 121 is movably connected to the cylinder body 10. The glue pushing member 20 includes a piston 201 and a push rod 202. The piston 201 is reciprocatingly arranged in the accommodating chamber 101. One end of the push rod 202 is connected to the piston 201 to drive the piston 201 to move.

[0136] The glue outlet nozzle structure 100 includes a glue outlet nozzle body 1, which has a glue outlet channel 11. The glue outlet nozzle body 1 includes a plurality of glue outlet walls 12 connected in sequence along the circumference of the glue outlet channel 11. The plurality of glue outlet walls 12 include two first glue outlet walls 121 arranged opposite to each other along a first direction and two second glue outlet walls 122 arranged opposite to each other along a second direction. The two first glue outlet walls 121 are located between the two second glue outlet walls 122. A first sealing layer is provided between the first glue outlet wall 121 and the second glue outlet wall 122. The two first glue outlet walls 121 are slidably connected to the second glue outlet wall 122, and one of the two first glue outlet walls 121 can move relative to the second glue outlet wall 122 along the first direction.

[0138] One end of the first glue outlet wall 121 adjacent to the glue outlet 102 forms a limit flange 1212 , and the inner wall of the cylinder body 10 forms a limit step surface.
