In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. designate square or station positional relationships as based on the square or station positional relationships shown in the drawings are merely for convenience of describing the present application and to simplify the description, and do not designate or imply that the apparatus or element being referred to must have, be constructed and operated with a specific square station, and thus should not be construed as limiting the present application.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

In industrial processes, it is often necessary to glue the outer and/or inner surfaces of the product using glue spreading means to achieve adhesion between the product and other components. Taking a box body with a product as a battery as an example, in the process of battery assembly, the inner bottom surface of the box body needs to be glued so that a battery monomer of the battery can be firmly glued and fixed with the box body when being accommodated in the box body. The box body is of an opening structure, and the inner bottom surface of the box body is a surface arranged towards the opening of the box body.

In traditional rubber coating device, the degree of accuracy of rubber coating is not high between box and the rubber coating subassembly, leads to the gluey type of rubber coating to take place to squint, and the rubber coating effect is relatively poor. However, the conventional glue spreading device is mainly used for spreading glue on the inner bottom surface of the box body, and the area of the inner bottom surface of the box body is larger, so that even if the glue spread glue is offset, the influence on the firmness of the adhesion of the battery cells or the battery modules is small.

When the conventional glue spreading device needs to be applied to glue spreading on a product with higher glue spreading accuracy, for example, when the conventional glue spreading device is used for spreading glue on an end face where an opening of a box body is located, disadvantages of the conventional glue spreading device are highlighted. Specifically, the end face of the box body with the opening is glued, and the box cover is covered at the opening of the box body, so that the box cover can be adhered to the box body, and the battery cell contained in the box body can be sealed.

However, since the majority of the area on the end face of the box having the opening is occupied by the opening, only a small annular area disposed around the opening is left available for gluing. Of course, the annular region is not necessarily an annular region, and may be an annular square region or the like. The width of the annular region is narrower, and if the glue spreading component shifts in the width direction of the annular region in the glue spreading process, the glue may not be spread on the annular region, so that the subsequent box body and the box cover are not firmly adhered.

Based on the above, the application provides a gluing device, which comprises a first positioning component, a gluing component and a second positioning component, wherein the first positioning component is used for mechanically positioning a box body or a transport trolley for carrying and transporting the box body, the second positioning component is used for acquiring a gluing starting point coordinate of a gluing surface in the component to be glued and a gluing point coordinate of the gluing component, and controlling the gluing component to move to a position enabling the gluing starting point coordinate to coincide with the gluing point coordinate when the two coordinates do not coincide.

In such a gluing device, when the coordinates of the glue spreading starting point and the coordinates of the glue spreading point are overlapped, the glue spreading starting point of the to-be-glued component is aligned with the glue spreading point of the glue spreading component, the positioning accuracy is high, and the subsequent glue spreading component can precisely spread glue according to the preset glue spreading track, so that a better glue spreading effect is achieved.

The embodiment of the application provides a gluing device 1, and the gluing device 1 can be used for gluing a box body on a battery production line, but is not limited to gluing other objects. For convenience of description, the following embodiments will take the gluing device 1 for gluing a box on a battery production line as an example.

Referring to fig. 1, fig. 2, fig. 3, and fig. 4, fig. 1 is a schematic structural diagram of a glue spreading device according to one or more embodiments of the present application, fig. 2 is a front view of the glue spreading device according to one or more embodiments of the present application, fig. 3 is a schematic structural diagram of a first positioning component for clamping a component to be glued according to one or more embodiments of the present application, and fig. 4 is a right side view of the first positioning component for clamping the component to be glued according to one or more embodiments of the present application.

In a first aspect, in one or more embodiments of the present application, the gluing device 1 includes a first positioning component 10, a gluing component 30, and a second positioning component 20, where the first positioning component 10 is used for mechanically positioning the component 2 to be glued, the gluing component 30 is used for gluing a gluing surface of the component 2 to be glued, and the second positioning component 20 is used for obtaining a gluing start point coordinate of the gluing surface of the component 2 to be glued and a glue outlet point coordinate of the gluing component 30, and controlling the movement of the gluing component 30 when the gluing start point coordinate and the glue outlet point coordinate do not coincide until the gluing start point coordinate and the glue outlet point coordinate coincide.

The first positioning component 10, the glue spreading component 30 and the second positioning component 20 may be directly placed on the ground in the external environment where the glue spreading device 1 is located, or a rack 60 may also be disposed in the glue spreading device 1, where the rack 60 is used for mounting the first positioning component 10, the glue spreading component 30 and the second positioning component 20, and may be specifically selected according to needs.

The first positioning assembly 10 is used for mechanically positioning the assembly 2 to be glued. The mechanical positioning is understood to mean the positioning and fixing of the assembly to be glued 2 by means of a mechanical structure not associated with the electronic control module.

The component to be glued 2 may comprise only the piece to be glued, which means a component with a gluing surface. Alternatively, the component to be glued 2 may also comprise a piece to be glued and a trolley 201 for carrying and transporting the piece to be glued. Taking the example that the member to be glued only includes the member to be glued, the first positioning assembly 10 is used for positioning the member to be glued. Taking the example that the member to be glued includes the member to be glued and the transportation trolley 201, the first positioning component 10 is used for positioning at least one of the member to be glued and the transportation trolley 201. The transport cart 201 includes a travelling body 2012 and a mounting plate 2011 disposed on the travelling body 2012, and a member to be glued is fixed on the mounting plate 2011. Therefore, when the first positioning assembly 10 positions at least one of the member to be glued and the transportation cart 201, the entire member to be glued 2 can be positioned.

The transport cart 201 may be an RGV cart (rail guided vehicle), an AGV cart (an electromagnetic or optical equipped automated navigation cart), or the like. The transporting trolley 201 transports the piece to be glued to the first positioning component 10 from the previous working procedure for mechanical positioning, and then the second positioning component 20 performs secondary positioning on the piece to be glued 2 and the gluing component 30, so as to realize accurate gluing. After the glue is applied, the transport trolley 201 drives the piece to be glued to transport to the next process.

For convenience of description, the following embodiments will take the case that the component 2 to be glued includes a piece to be glued and a transportation trolley 201, the piece to be glued is a box on a battery production line, and the gluing device 1 is used for gluing an end face of an opening of the box as an example.

The first positioning assembly 10 may coarsely position the transportation cart 201 in at least one of the first direction P1, the second direction P2, and the third direction P3. For example, the angles between the first direction P1 and the second direction P2, the second direction P2 and the third direction P3, and the angles between the second direction P2 and the third direction P3 may be set according to the needs, which is not limited herein. For convenience of description, the following embodiments are all perpendicular to each other in the first direction P1, the second direction P2, and the third direction P3, where the first direction P1 is the length direction of the transportation cart 201 in the state where the glue spreading device 1 in fig. 1 is located, the second direction P2 is the width direction of the transportation cart 201, and the third direction P3 is the height direction of the transportation cart 201.

The second positioning component 20 is an electric control component, and is configured to automatically obtain a glue spreading start point coordinate of a glue spreading surface of the component to be glued 2 and a glue dispensing point coordinate of the glue spreading component 30, and control the glue spreading component 30 to move to a position where the glue spreading start point coordinate and the glue dispensing point coordinate coincide when the glue spreading start point coordinate and the glue dispensing point coordinate do not coincide. And then, the second positioning assembly 20 drives the gluing assembly 30 to glue according to a preset gluing track until the gluing is completed.

The gluing starting point refers to a starting point of gluing on a gluing surface according to a preset gluing track. The coordinates of the start point of the glue are the coordinates of the start point of the glue on the glue surface in the space coordinate system where the glue device 1 is located, the start point of the glue is defined as a, and the coordinates of the start point of the glue are defined as a (X1, Y1). The glue outlet point of the glue spreading assembly 30 refers to a point where a plane where the glue outlet of the glue spreading assembly 30 is located intersects with the central axis of the glue outlet. The coordinates of the glue dispensing point of the glue dispensing assembly 30 refer to the coordinates of the glue dispensing point of the glue dispensing assembly 30 in the above-mentioned space coordinate system, where the coordinates of the glue dispensing point are defined as B, and the coordinates of the glue dispensing point are defined as B (X2, Y2).

X1 refers to the coordinate value of the glue starting point in the X direction in the space coordinate system, Y1 refers to the coordinate value of the glue starting point in the Y direction perpendicular to the X direction in the space coordinate system, X2 refers to the coordinate value of the glue point in the X direction in the space coordinate system, and Y2 refers to the coordinate value of the glue point in the Y direction in the space coordinate system. The spatial coordinate system also has a Z direction, which is a direction perpendicular to both the X direction and the Y direction.

The following embodiments are described with respect to the case where the X direction is one horizontal direction in the state where the glue spreading device 1 in fig. 1 is located, the Y direction is another horizontal direction perpendicular to the X direction in the state where the glue spreading device 1 in fig. 1 is located, the Z direction is a vertical direction perpendicular to the X direction and the Y direction in the state where the glue spreading device 1 in fig. 1 is located, the X direction is parallel to the first direction P1, the Y direction is parallel to the second direction P2, and the Z direction is parallel to the third direction P3.

The coordinates of the glue spreading start point and the coordinates of the glue spreading point are not coincident, which means that X1 and X2 are not equal and/or Y1 and Y2 are not equal. The coordinates of the glue spreading start point and the glue spreading point coincide, which means that X1 is equal to X2, and Y1 is equal to Y2. When the coordinates of the glue spreading start point and the coordinates of the glue spreading point are overlapped, the positions of the glue spreading start point and the glue spreading point in the Z direction in the space coordinate system are aligned, so that the glue spreading can be conveniently positioned.

It is understood that the fact that the glue spreading start point and the glue outlet point are aligned in the Z direction in the spatial coordinate system means that the glue spreading start point and the glue outlet point are coincident or spaced apart in the Z direction. In order to facilitate glue discharge, a glue spreading start point and a glue discharge point are generally arranged at intervals when being aligned in the Z direction in a space coordinate system.

In the present application, by providing the first positioning component 10 and the second positioning component 20, the first positioning component 10 can perform coarse positioning on the component 2 to be glued. After the positioning of the first positioning component 10 is completed, the position of the to-be-glued component 2 is fixed, and then the second positioning component 20 is used for precisely positioning the glue spreading starting point coordinate of the to-be-glued component 2 and the glue spreading point coordinate of the glue spreading component 30, so that the risk that the glue spreading point of the glue spreading component 30 is offset relative to the glue spreading starting point is reduced, and the positioning accuracy is better, and furthermore, the glue spreading accuracy is also better, and the glue spreading effect is better.

Referring to fig. 3 and 4 again, and referring to fig. 5, fig. 5 is a schematic structural diagram of a first positioning component according to one or more embodiments of the present application.

In one or more embodiments of the application, the first positioning assembly 10 comprises positioning members 11 arranged on opposite sides of the assembly 2 to be glued, each positioning member 11 being configured to jointly clamp the assembly 2 to be glued.

The positioning members 11 may be disposed on both sides of the transportation cart 201 along any one of the first direction P1, the second direction P2, and the third direction P3. For convenience of description, the following embodiments will take the positioning members 11 distributed on two sides of the transportation cart 201 along the second direction P2 as an example. That is, the following embodiments are each described taking the example that the positioning pieces 11 are distributed on both sides of the transportation cart 201 in the width direction of the transportation cart 201.

In addition, the first positioning component 10 may include, but is not limited to, positioning the transportation vehicle along the second direction P2 by including the positioning component 11, for example, the first positioning component 10 may further include a first positioning component and a second positioning component, where the first positioning component positions the transportation vehicle 201 along the first direction P1, and the second positioning component positions the transportation vehicle 201 along the third direction P3. It should be noted that the first limiting member and the second limiting member are conventional technical means in the art, and therefore are not described herein.

The positioning members 11 are two and distributed on two opposite sides of the transportation trolley 201. Illustratively, the positioning member 11 may be of a unitary structure or of a split structure. Wherein, the positioning member 11 is an integral structure, which means that each part in the positioning member 11 is integrally formed. The positioning member 11 is of a split type structure, and each part in the positioning member 11 is formed separately and then connected by welding, detachable connection or other connection modes.

In actual operation, the transporting trolley 201 carries the to-be-glued piece and moves between the two positioning pieces 11 along the first direction P1, and then the positioning pieces 11 located at two sides of the transporting trolley 201 clamp the to-be-transported trolley 201 together to fix the transporting trolley 201 and the to-be-glued piece.

In this embodiment, the positioning members 11 are distributed on both sides of the transportation cart 201 and the arrangement form of clamping the transportation cart 201 is simple and convenient to operate.

In one or more embodiments of the present application, each positioning member 11 includes a base 111, a positioning portion 112, and an elastic portion 113 connected between the positioning portion 112 and the base 111; the positioning portions 112 are used for clamping the component 2 to be glued together by means of the elastic force of the elastic portion 113 connected with the positioning portions.

Specifically, the positioning portion 112 may include a plurality of positioning sub-portions disposed along the first direction P1. The elastic portion 113 connected to the positioning sub-portion has a plurality of elastic sub-portions, and among the elastic portion 113 and the positioning portion 112 connected to each other, all the positioning sub-portions are connected in one-to-one correspondence with all the positioning sub-portions, and each elastic sub-portion is connected between the corresponding positioning sub-portion and the base 111. Of course, the structure of the positioning portion 112 is not limited to the above-described one, for example, the positioning portion 112 includes only one positioning sub-portion, and the positioning sub-portion extends along the first direction P1, and the elastic member includes only one elastic sub-portion.

The elastic member may be a spring, an elastic block, or other elastic structure, and is not limited herein.

In actual operation, before the transportation cart 201 enters between the two positioning members 11, each elastic portion 113 may be in a compressed state or a natural straightened state, and each positioning portion 112 is located at an initial position. In the process that the transport trolley 201 carries the piece to be glued between the two positioning pieces 11, each positioning portion 112 compresses the elastic portion 113 connected with each other by means of the pressing of the transport trolley 201, so that each elastic portion 113 contracts. Since the forces are opposite, each positioning portion 112 presses against the transportation cart 201 under the elastic force of each elastic portion 113, so that the transportation cart 201 can be clamped and fixed to facilitate the subsequent gluing. After the gluing is completed, the transport trolley 201 drives the piece to be glued to withdraw from between the two pieces to be glued. Under the action of the elastic parts 113, the positioning parts 112 are reset to the initial positions so as to prepare for the next gluing.

By providing the seat body 111, the elastic portion 113 and the positioning portion 112, each elastic portion 113 is contracted, so that not only can the transportation trolley 201 be clamped, but also the transportation trolley 201 with different widths can be clamped, and the positioning reliability and the positioning compatibility are excellent.

In one or more embodiments of the present application, each positioning member 11 includes a guide section 1121 and a clamping section 1124 connected to each other, and each elastic portion 113 abuts against the clamping section 1124 of the respective connected positioning member 11;

the guide section 1121 of each positioning member 11 encloses a guide channel 1123, and the clamping section 1124 of each positioning member 11 encloses a clamping channel 1126, the guide channel 1123 being used for guiding the component 2 to be glued into the clamping channel 1126.

Specifically, the guide section 1121 and the clamping section 1124 are disposed and communicate along the first direction P1. The guide section 1121 of each positioning member 11 has a guide surface 1122 surrounding a guide passage 1123, and the guide surface 1122 may be a straight surface or an inclined surface. Illustratively, the guide surface 1122 is an inclined surface, and the inclined surface of each positioning member 11 encloses a channel width (the dimension of the guide channel 1123 in the second direction P2) of the formed guide channel 1123 gradually decreases in the direction in which the guide channel 1123 points to the clamp channel 1126. The clamping section 1124 of each positioning member 11 has a clamping surface 1125 surrounding the formed clamping channel 1126, the clamping surface 1125 being a straight surface, and the channel width of the clamping channel 1126 (the dimension of the clamping channel 1126 in the second direction P2) of the clamping surface 1125 surrounding the formed clamping channel 1126 of each positioning member 11 remains substantially unchanged in the direction in which the guide channel 1123 is directed toward the clamping channel 1126. In addition, the channel width of the clamping channel 1126 is equal to the minimum value of the channel width of the guide channel 1123.

In direct operation, the trolley 201 travels from the guide channel 1123 to the clamp channel 1126 for clamping. The channel width of the guide channel 1123 is generally greater than the dimension of the trolley 201 in the second direction P2, so that the trolley 201 experiences little or possibly zero clamping force from each of the positioning members 11 during travel of the trolley 201 within the guide channel 1123. As the guide passage 1123 is further tightened, the gap between the transportation carriage 201 and the guide surface 1122 of the guide passage 1123 gradually decreases, and further, when the transportation carriage 201 moves to the opening where the guide passage 1123 communicates with the clamping passage 1126, the transportation carriage 201 is pressed by the guide surface 1122 and can be clamped between the positioning portions 112 of the respective positioning members 11 when entering into the clamping passage 1126.

In this embodiment, the guide channel 1123 is capable of guiding the transportation cart 201 into the clamping channel 1126 and clamping within the clamping channel 1126, and the provision of the guide channel 1123 promotes the reliability with which the transportation cart 201 enters the clamping channel 1126 and is clamped, so that the transportation cart 201 can be positioned.

Referring to fig. 1 and 2 again, and also referring to fig. 6, fig. 6 is a schematic structural diagram of a second positioning component of the glue spreading device and a glue spreading component according to one or more embodiments of the present application.

In one or more embodiments of the present application, the second positioning assembly 20 includes a photographing element 21, a driving element 22 and a controller 23, wherein the photographing element 21 and the driving element 22 are electrically connected to the controller 23, and the driving element 22 is in transmission connection with the glue coating assembly 30;

the photographing element 21 is used for photographing a current image of the glue spreading device 1, and the controller 23 is used for judging whether the glue spreading start point coordinates and the glue outlet point coordinates are coincident according to the current image, and controlling the driving element 22 to drive the glue spreading assembly 30 to move when the glue spreading start point coordinates and the glue outlet point coordinates are not coincident.

The driving member 22 may be a member capable of moving in at least one of the first direction P1, the second direction P2 and the third direction P3 to move the glue assembly 30. The driving member 22 is illustratively a three-axis manipulator, which can drive the glue assembly 30 to move in the first direction P1, the second direction P2, and the third direction P3.

The photographing member 21 may be a 2D photographing member or a 3D photographing member. Which may be provided on the frame 60 or on the driving member 22. Illustratively, the camera 21 is disposed on the drive member 22 and moves in synchronization with the glue assembly 30.

The controller 23 is a control module with an image processing function, for example, the controller 23 may be a single-chip microcomputer. The controller 23 may be provided on the frame 60, on the ground or on a wall surface in the external environment where the gluing device 1 is located.

The shooting piece 21 shoots the current image of the gluing device 1 and feeds the current image back to the controller 23, and the specific process of judging whether the gluing start point coordinates and the gluing outlet point coordinates coincide or not by the controller 23 according to the current image is as follows: the controller 23 obtains the glue starting point identification coordinate of the glue spreading surface of the glue spreading component 2 in the current image and the glue outlet point identification coordinate of the glue spreading component 30 in the current image, and judges whether the glue starting point identification coordinate is equal to the glue outlet point identification coordinate. If the controller 23 determines that the dispensing point identification coordinate of the glue dispensing assembly 30 is equal to the dispensing point identification coordinate, it indicates that the dispensing start point coordinate of the glue dispensing surface of the glue dispensing assembly 2 in the glue dispensing device 1 is equal to the dispensing point coordinate of the glue dispensing assembly 30. If the controller 23 determines that the dispensing point identification coordinates of the glue dispensing assembly 30 are not equal to the dispensing point identification coordinates, it is indicated that the dispensing start coordinates of the glue dispensing surface of the glue dispensing assembly 2 and the dispensing point coordinates of the glue dispensing assembly 30 in the glue dispensing device 1 are not equal. Further, the controller 23 controls the glue spreading component 30 to move in the X direction and/or the Y direction until the glue spreading start point coordinates of the glue spreading surface of the glue spreading component 2 in the glue spreading device 1 and the glue dispensing point coordinates of the glue spreading component 30 are equal. Afterwards, the controller 23 controls the driving member 22 to drive the gluing assembly 30 to glue according to the preset gluing track.

It should be noted that the glue outlet mark refers to the glue outlet of the glue spreading assembly 30 in the current image, and the glue spreading start mark refers to the glue spreading start on the glue spreading surface in the current image. The dispensing point identification coordinates refer to coordinates of the dispensing point identification in the current image in the virtual space of the controller 23. The glue start point identification coordinates refer to coordinates of the glue start point identification in the current image in the virtual space of the controller 23.

In this embodiment, by setting the driving member 22, the photographing member 21 and the controller 23, accurate positioning between the glue spreading component 30 and the component to be glued 2 can be achieved, and better glue spreading effect is achieved.

In one or more embodiments of the present application, the glue application device 1 further includes a collection assembly 40 electrically connected to the controller 23, where the collection assembly 40 is configured to collect a glue pattern image of the glue application surface on the component to be glued 2, and the controller 23 is configured to control the glue application assembly 30 to return to the actual glue breaking area corresponding to the glue breaking area when the glue breaking area in the glue pattern exists.

The acquisition component 40 may be a 2D image acquisition component 40, or may be a 3D image acquisition component 40. Illustratively, the acquisition component 40 employs a 3D image acquisition component 40. Since deformation may occur during the production or transportation of the piece to be glued, the gluing surface is deformed and bent, and the 3D image acquisition assembly 40 can acquire a non-planar glue type image, thereby obtaining a more accurate glue type image.

Specifically, the pick up assembly 40 is drivingly connected to the drive member 22, and the glue assembly 30 is coupled to the pick up assembly 40. The collecting assembly 40 and the gluing assembly 30 synchronously move and are used for collecting glue images formed by gluing the gluing assembly 30 on a gluing surface in real time and judging the gluing effect in real time, so that the judging time of the gluing effect is saved, and the gluing efficiency is high.

The structure of the collecting assembly 40 may be various, for example, the collecting assembly 40 includes only one collecting member 41. In the process of gluing, the gluing area formed on the gluing surface by the gluing component 30 always falls in the collecting area of the collecting piece 41, so as to ensure that the collecting piece 41 can collect the glue type image in real time and accurately. Or, the collecting member 41 may also include a base 42 and a plurality of collecting members 41, where the base 42 is in transmission connection with the driving member 22, and the base 42 is provided with a clearance hole penetrating through the base 42 along the third direction P3, the glue coating assembly 30 is penetrated in the clearance hole along the third direction P3, and all the collecting members 41 are disposed around the circumference of the glue coating assembly 30. In the process of gluing, the gluing area formed by the gluing component 30 on the gluing surface always falls in the total collection area formed by combining the collection areas of all the collection pieces 41, so as to ensure that the collection pieces 41 can collect glue images in real time and accurately. The collection area is an area where the collection material 41 can collect on the adhesive surface. The total collection area refers to the collection of areas that can be collected by the individual collecting members 41 on the adhesive surface.

The collecting assembly 40 is used for collecting a glue image formed by applying glue to the glue coating assembly 30, and feeding the glue image back to the controller 23. The controller 23 compares the glue area in the glue pattern with the standard glue area in the standard glue pattern and determines whether the glue quality is acceptable. If the glue spreading area in the glue type image does not have the glue breaking area, glue supplementing is not needed. If the glue spreading area in the glue pattern image has a glue breaking area, the controller 23 determines an actual glue breaking area on the glue spreading surface according to the glue breaking area in the glue pattern image, and controls the glue spreading assembly 30 to move to the actual glue breaking area for glue supplementing. After the glue is applied, the controller 23 controls the glue applying assembly 30 to continue to apply glue according to the preset glue applying track.

It should be noted that, the glue breaking area of the glue spreading area in the glue pattern image refers to the glue breaking area of the glue pattern image, and the actual glue breaking area refers to the glue breaking area on the glue spreading surface.

Therefore, the collection assembly 40 is arranged, so that the gluing device 1 can automatically detect the gluing effect, and automatically repair the glue when the glue is broken, and has better gluing effect.

Referring to fig. 7, fig. 7 is a front view of a glue assembly of a glue device according to one or more embodiments of the application.

In one or more embodiments of the present application, the glue assembly 30 includes a glue head 31 and a heating element 33 coupled to the glue head 31, wherein the heating element 33 is configured to be turned on when the temperature value of the glue head 31 is lower than a preset temperature threshold.

The heating element 33 may be located outside the applicator head 31 or at least partially extend into the applicator head 31. Illustratively, the heating element 33 is disposed to be sleeved outside the glue head 31, so as to facilitate the installation of the heating element 33.

The heating element 33 may be an electromagnetic heating element 33, an infrared heating element 33, a resistance heating element 33, or the like, and the specific form thereof is not limited herein, and only the applicator head 31 needs to be heated.

The manner of acquiring the temperature value of the glue head 31 may be detected by the temperature detecting member 32, or may be obtained by human perception. Taking the human sensing as an example, when the user senses that the temperature value of the glue spreading head 31 is lower than the preset temperature threshold by touching the glue spreading head 31, the user starts the heating element 33, so that the heating element 33 can heat the glue spreading head 31, and then, heat is transferred to the glue in the glue spreading head 31, so that the temperature of the glue is increased.

If the temperature of the gel is too low during the flow of the gel, the gel has poor fluidity and tends to clog the applicator head 31. In addition, the temperature of the glue head 31 characterizes the temperature of the glue in the glue head 31, and when the temperature of the glue head 31 is lower than the preset temperature threshold, the temperature of the glue is lower, the fluidity is worse, and the glue is easy to be drawn and blocked.

In this embodiment, by providing the heating element 33 on the glue spreading head 31, when the temperature value of the glue spreading head 31 is lower than the preset temperature threshold, the heating element 33 is turned on, and the heat on the heating element 33 is transferred to the glue in the glue spreading head 31 through the glue spreading head 31, so that the fluidity of the glue is better, thereby helping to promote the fluidity of the glue, so that the glue flows out smoothly and reliably.

In one or more embodiments of the present application, the glue assembly 30 further includes a temperature detecting member 32, the temperature detecting member 32 is electrically connected to the heating member 33, and the temperature detecting member 32 is used for collecting a temperature value of the glue head 31.

The temperature detecting member 32 may be a pressure type temperature sensor, a resistance type temperature sensor, or the like, and may be specifically selected according to the requirement.

Specifically, the temperature detecting member 32 may be electrically connected to an external terminal or the controller 23. It will be appreciated that the external terminal and the controller 23 are both one of the above-mentioned electronic control modules. When the temperature detecting member 32 is connected with an external terminal, the temperature detecting member 32 transmits the collected temperature value to the terminal, and a user can know the temperature value of the glue spreading head 31 according to the display data of the terminal. When the temperature value of the glue head 31 is lower than the preset temperature threshold, the external terminal sends a signal to the heating element 33 and controls the heating element 33 to be turned on. Or, when the temperature detecting element 32 is electrically connected to the controller 23, the controller 23 directly determines whether the temperature value is less than the preset temperature threshold according to the temperature value fed back by the temperature detecting element 32, and if yes, controls the heating element 33 to be turned on so as to heat the glue spreading head 31.

By providing the temperature detecting member 32, the trouble of manual monitoring is reduced, and the intellectualization of the detection of the glue spreading device 1 can be realized.

In one or more embodiments of the present application, the gluing device 1 further comprises at least two glue supply assemblies 50 coupled to the frame 60, the gluing assembly 30 being selectively in fluid communication with one of the whole glue supply assemblies 50.

The glue supply assembly 50 may include a glue supply pump and a glue storage element, wherein the glue storage element is used for storing glue, and the glue supply pump is in fluid communication with the glue application head 31 in the glue application assembly 30 and is used for driving the glue in the glue storage element to flow to the glue application head 31 so as to apply glue.

Of course, the specific form of the glue supply assembly 50 is not limited to the above, and it may have other structures, and may be specifically set as required.

By providing at least two glue supply assemblies 50, when the glue application assembly 30 is selectively in fluid communication with one of the glue supply assemblies 50, glue in the glue supply assembly 50 in fluid communication with the glue application assembly 30 can be fed into the glue application head 31 for glue application, and when the glue in the glue supply assembly 50 is used up, the glue supply assembly 50 can be replaced in time, and the glue application assembly 30 is in fluid communication with other glue supply assemblies 50 containing glue. Under this kind of design, compare with the rubber coating device 1 that only sets up a confession gluey subassembly 50, the time of changing confession gluey subassembly 50 is shorter, is convenient for promote rubber coating efficiency.

In a second aspect, the application also provides a battery production line comprising a gluing device 1 according to any one of the embodiments described above. The gluing device 1 is used for gluing the end face provided with the opening on the box body on the battery production line.

For example, in the previous process, the battery cell or the battery module is assembled into the case, then the case is conveyed to the position where the glue spreading device 1 is located, the glue spreading device 1 spreads glue on the end face of the case having the opening, and after the glue spreading is completed, the case is conveyed to the next process and is sealed by the case cover.

In such a gluing device 1, the first positioning assembly 10 can perform a coarse positioning of the assembly to be glued 2. After the positioning of the first positioning component 10 is completed, the position of the to-be-glued component 2 is fixed, and then the second positioning component 20 is used for precisely positioning the glue spreading starting point coordinate of the to-be-glued component 2 and the glue spreading point coordinate of the glue spreading component 30, so that the risk that the glue spreading point of the glue spreading component 30 is offset relative to the glue spreading starting point is reduced, and the positioning accuracy is better, and furthermore, the glue spreading accuracy is also better, and the glue spreading effect is better.
