[0054] Example 1

[0055] like Figure 1 As shown, this embodiment provides a glue coating device having an X direction, a Y direction and a Z direction intersecting with each other.

[0056] In some embodiments, the X direction, the Y direction, and the Z direction intersect each other perpendicularly.

[0057] In a specific embodiment, Figures 1 to 8 As shown, the glue coating device 10 of this embodiment includes a driving component 120, a glue injection component 150 and a glue scraping component 130; wherein, the driving component 120 includes a driving member 121, the glue injection component 150 includes a glue outlet nozzle 155, and the glue scraping component 130 includes a glue scraper 131, the glue scraper 131 is connected to the driving member 121, and the glue scraper 131 is located on the side of the glue outlet nozzle 155 in the Y direction, so that when coating the glue, the glue scraper 131 can move along the Y direction and spread the glue, while ensuring the thickness of the glue layer, it can avoid the phenomenon of glue shortage; wherein, the driving member 121 can drive the glue scraper 131 to move relative to the glue scraper 131 along the Z direction, so that the glue scraper 131 can cooperate with the glue outlet nozzle 155 and remove the excess glue located at the glue outlet nozzle 155. In this way, by setting the driving member 121, the scraper plate 131 can be driven to move in the Z direction to ensure that the distance between the scraper plate 131 and the surface to be coated with glue is quantified, and the thickness of the glue layer after scraping glue is ensured to be relatively uniform; in addition, after the glue coating is completed, the driving member 121 can drive the scraper plate 131 to move upward along the Z direction, so that the scraper plate 131 and the glue outlet nozzle 155 form a scissor-type structure, which can remove the residual glue at the glue outlet nozzle 155 and prevent the residual glue from forming burrs after the residual glue is solidified, thereby affecting the thickness and uniformity of the scraped layer.

[0058] In this embodiment, the cooperation of the driving member 121, the scraper plate 131 and the glue nozzle 155 can realize automatic cleaning of the glue nozzle without manual cleaning, thereby improving the gluing efficiency and preventing residual glue from accidentally falling into the glued area.

[0059] In some embodiments, the driving member 121 is a pneumatic cylinder, an oil cylinder or a linear motor, and the scraper plate 131 is disposed at the output end of the driving member 121 .

[0060] In some embodiments, see Figure 4In order to ensure that the residual glue of the glue outlet nozzle 155 can be cleaned after glue coating, the scraper plate 131 is provided with a first abutting surface 133, and the first abutting surface 133 faces the glue outlet nozzle 155 in the Y direction; the glue injection assembly 150 also includes a glue injection tube 154, and the glue outlet nozzle 155 is connected to the glue injection tube 154, and the glue outlet nozzle 155 is provided with a second abutting surface 155a, and the second abutting surface 155a is provided at an end of the glue outlet nozzle 155 away from the glue injection tube 154, and the second abutting surface 155a faces the first abutting surface 133 in the Y direction; wherein the driving member 121 can drive the scraper plate 131 to move along the Z direction, so as to The first abutting surface 133 is enabled to approach or abut against the second abutting surface 155a, and the residual glue at the glue outlet nozzle 155 is removed. That is, after the glue coating is completed, the first abutting surface 133 moves upward along the Z direction under the drive of the driving member 121. When the first abutting surface 133 approaches or abuts against the second abutting surface 155a, the first abutting surface 133 and the second abutting surface 155a form a scissor-like structure, thereby removing the residual glue at the glue outlet nozzle 155, which can prevent the residual glue from accidentally falling into the glue-coated area, and can also prevent the glue liquid at the glue outlet of the glue outlet nozzle 155 from solidifying or the residual glue from forming burrs, thereby affecting the thickness and uniformity of the glue layer.

[0061] It should be noted that the scissors have two blades, which are hinged together. When the two blades rotate relative to each other, the edges of the blades approach each other and squeeze the object located therein into two parts by squeezing, thereby achieving cutting. The scissor-type structure here means that when the first abutting surface 133 and the second abutting surface 155a are close to or abutting each other, the distance between the closest parts of the two is also reduced, thereby squeezing the object located therebetween into two parts by squeezing, that is, the residual glue remaining on the glue outlet nozzle 155 is removed when the driving member 121 drives the glue scraper When the plate 131 moves upward, the first abutting surface 133 approaches the second abutting surface 155a of the glue outlet nozzle 155. At this time, the residual glue remaining in the glue outlet nozzle 155 is located between the first abutting surface 133 and the second abutting surface 155a. When the first abutting surface 133 and the second abutting surface 155a approach to a certain degree or abut against each other, the distance between the first abutting surface 133 and the second abutting surface 155a is reduced and the residual glue is squeezed, thereby separating the residual glue into a part that is basically not outside the glue outlet nozzle 155 and a part squeezed out from the glue outlet nozzle 155, thereby removing the residual glue.

[0062] In some embodiments, the first abutting surface 133 has a first bottom edge 133a, the first bottom edge 133a extends along the X direction, and the first bottom edge 133a is parallel to the second abutting surface 155a, and the first bottom edge 133a can abut against the second abutting surface 155a to remove the residual glue located at the glue outlet 155. The first bottom edge 133a is parallel to the second abutting surface 155a, so that when the first abutting surface 133 approaches or abuts against the second abutting surface 155a, the distance between the first abutting surface 133 and the second abutting surface 155a can be made smaller or the joint can be more tightly closed, so that all the residual glue can be removed as cleanly as possible, thereby improving the thoroughness of removing the residual glue.

[0063] In some embodiments, Figure 4 As shown, during the glue coating process, the height of the first bottom edge 133a in the Z direction is lower than the height of the glue outlet of the glue nozzle 155. After the glue nozzle 155 discharges glue, the glue liquid is scraped flat by the scraper 131. The height difference H between the first bottom edge 133a and the bottom surface of the box body 30 limits the glue coating thickness to ensure uniform glue coating thickness.

[0064] In other embodiments, the first abutting surface 133 and the second abutting surface 155a are arranged at an acute angle, so that when the driving member 121 drives the first abutting surface 133 to move upward along the Z direction, it can also form a scissor-type structure with the second abutting surface 155a, thereby removing the residual glue from the glue outlet 155. The first abutting surface 133 and the second abutting surface 155a are arranged at an acute angle, and when the two abut, they will inevitably contact and squeeze out the residual glue, thereby improving the effect of removing the residual glue.

[0065] In some embodiments, in order to further ensure the uniformity of the glue coating thickness, the scraper assembly 130 also includes a roller 132, and two rollers 132 are provided and are respectively arranged at the opposite ends of the scraper plate 131 along the X direction, and the end of the roller 132 away from the driving member 121 in the Z direction is lower than the scraper plate 131; thus, during the glue coating process, the lower edge of the roller 132 is in contact with the bottom surface of the box 30, and the plane where the lower edge of the roller 132 is located and the plane where the lower edge of the roller 132 is located and the plane where the lower edge of the scraper plate 131 is located form a height difference H that limits the glue coating thickness in the third direction Z, thereby ensuring the uniformity of the glue coating thickness.

[0066] In other embodiments, since the roller 132 has a thickness value, the design of the roller 132 cannot ensure 100% coverage of the scraping surface that is larger than the width of the first abutting surface 133. For this reason, the roller 132 can be replaced by a roller, and the line contact between the roller 132 and the bottom surface of the box body 30 is improved to a ball point contact, thereby increasing the scraping coverage area.

[0067] In some embodiments, the scraper plate 131 is provided with two mounting portions 134, the two mounting portions 134 are spaced apart in the X direction, the first abutting surface 133 is located between the two mounting portions 134, and at least a portion of the glue nozzle 155 is located between the two mounting portions 134, and the roller 132 is installed on the corresponding mounting portion 134. The two rollers 132 are respectively installed on the corresponding mounting portions 134, and since at least a portion of the glue nozzle 155 is located between the two mounting portions 134, the two mounting portions 134 can limit the glue nozzle 155 to a certain extent, so as to prevent the glue nozzle 155 from moving in the X direction.

[0068] Optionally, the mounting portion 134 is roughly a plate extending along the Y direction, and the two mounting portions 134 both extend along the Y direction toward one side of the glue outlet nozzle 155, so that the two mounting portions 134 and the hanging stirring 131 form a "U"-shaped structure. During the gluing process, the roller 132 abuts against the bottom surface of the box body 30, which can effectively prevent the glue from overflowing from both ends of the first abutting surface 133 during gluing, and can also ensure the thickness and uniformity of the glue layer, thereby improving the gluing quality and efficiency.

[0069] In some embodiments, the roller 132 is detachably mounted on the mounting portion 134, and the height difference H can be limited by replacing rollers 132 of different radii to meet the requirements of glue coating thickness of different products. In other embodiments, the roller 132 and the bottom surface of the box 30 are in rolling friction to prevent scratching the coating on the surface of the product.

[0070] In some embodiments, in order to ensure that the roller 132 always contacts the bottom surface of the box 30 during the gluing process, the gluing device 10 further includes a floating component 110, which can apply pressure in the Z direction to the scraper 131, so that the roller 132 always contacts the bottom surface of the product box, thereby ensuring the thickness and uniformity of the glue layer. Figure 5 and Figure 6 The floating assembly 110 includes a mounting frame 111, a floating frame 115 and an elastic member 113. The floating frame 115 is slidably installed on the mounting frame 111 along the Z direction. The driving assembly 120 is installed on the floating frame 115. The elastic member 113 is arranged between the floating frame 115 and the mounting frame 111 to be able to apply pressure along the Z direction to the scraper plate 131, that is, the elastic member 113 is always in a compressed state. When the driving member 121 is locked, when the bottom surface of the box body 30 is in a non-planar state, it can also ensure that the roller 132 always remains in contact with the bottom surface of the box body 30, can automatically adapt to the flatness of the box body, improve the gluing efficiency, and ensure the thickness and uniformity of the glue layer.

[0071] The mounting frame 111 is fixedly arranged, and the floating assembly 110 applies pressure to the scraper plate 131 along the Z direction toward the bottom surface of the box body 30, so that the roller 132 is always in contact with the bottom surface of the box body 30, thereby ensuring that the thickness of the glue layer after scraping the glue is always the height difference H between the scraper plate 131 and the roller 132 in the Z direction toward the bottom surface of the box body 30.

[0072] In some embodiments, the floating frame 115 includes a first connecting frame 115a extending along the Z direction and a second connecting frame 115b extending along the Y direction, and the second connecting frame 115b is connected to the first connecting frame 115a; the first connecting frame 115a is slidably connected to the mounting frame 111 in the Z direction; the driving assembly 120 is arranged on the second connecting frame 115b, and the first connecting frame 115a and the driving assembly 120 are located on opposite sides of the mounting frame 111 in the Y direction, and the elastic member 113 is arranged between the mounting frame 111 and the second connecting frame 115b; thus, after the elastic member 113 is installed, it exerts pressure on the scraper plate 131 in the Z direction to ensure that the roller 132 always remains in contact with the bottom surface of the box body 30, and at the same time, it can also avoid interference in the movements of the driving assembly 120, the glue injection assembly 150 and the scraper assembly 130.

[0073] Optionally, the elastic member 113 may be a spring, and there may be one spring or a plurality of springs which are spaced apart along the X direction.

[0074] In some embodiments, the floating assembly 110 also includes a guide rail 117 and a slider 118. The guide rail 117 extends along the Z direction and is arranged on the mounting frame 111. The slider 118 can be slidably installed on the guide rail 117 along the Z direction. The first connecting frame 115a is connected to the slider 118, so as to realize the floating of the floating frame 115 in the Z direction, ensuring that the roller 132 can always abut against the bottom surface of the box 30.

[0075] In some embodiments, the guide rails 117 are preferably provided in two groups and are arranged opposite to each other along the X-direction, so as to ensure the linearity of the movement of the floating assembly 110 along the Z-direction.

[0076] In some embodiments, the floating assembly 110 also includes a fixed plate 112, which is disposed on the second connecting frame 115b, and the fixed plate 112 is level with the bottom surface of the mounting frame 111, and the elastic member 113 is disposed between the fixed plate 112 and the mounting frame 111, so as to ensure the stability of the force applied to the elastic member 113, and ensure that the pressure applied by the elastic member 113 to the scraper plate 131 along the Z direction is stable, thereby ensuring the thickness and uniformity of the glue layer.

[0077] In some embodiments, to prevent the second connecting frame 115b from abnormally moving toward the mounting frame 111 and causing mechanical friction or even damage, the floating assembly 110 further includes a stopper 116 disposed on the mounting frame 111 or the floating frame 115 along the Z direction.

[0078] In some embodiments, the stopper 116 is a stop bolt, which can adjust and define the gap between the second connecting frame 115b and the mounting frame 111 to meet the floating requirement in a non-planar state, thereby ensuring the thickness of the glue layer.

[0079] In some embodiments, a pressure sensor 114 is provided on the mounting frame 111 or the floating frame 115, wherein the pressure sensor 114 and the stopper 116 are arranged relative to each other in the Z direction; the pressure sensor 114 can be used to monitor the pressure value between the mounting frame 111 and the floating frame 115 at all times. When the stopper 116 and the pressure sensor 114 abut in the Z direction, if the pressure reaches the set upper limit value, the gluing device 10 stops operating to prevent the mounting frame 111 and the floating frame 115 from colliding with each other or other abnormal situations, and the abnormal situation is fed back to the background system to prompt the maintenance personnel to handle it.

[0080] In some embodiments, the pressure sensor 114 can also be used to debug and calibrate the glue coating device 10 before glue coating to ensure the accuracy of subsequent glue coating.

[0081] In some embodiments, the glue coating device 10 further includes a support frame 140 , and the floating assembly 110 and the glue injection assembly 150 are both mounted on the support frame 140 .

[0082] In some embodiments, the glue injection assembly 150 further includes a locking member 156 , which is connected to the support frame 140 , and the glue nozzle 155 and the glue injection tube 154 are connected and locked via the locking member 156 to facilitate replacement or correction of the glue nozzle 155 .

[0083] In some embodiments, the glue injection assembly 150 further includes a seal 157, and the seal 157 is used to seal the glue outlet nozzle 155 and the glue injection tube 154 to prevent leakage from affecting the glue coating quality of the product.

[0084] In some embodiments, Figure 6 and Figure 7 As shown, the glue injection assembly 150 also includes a first glue supply tube 151, a second glue supply tube 152 and a mixing glue head 153, wherein the mixing glue head 153 is installed on the support frame 140, wherein the liquid outlet end of the mixing glue head 153 is connected to the glue injection tube 154, and the first glue supply tube 151 and the second glue supply tube 152 are both connected to the liquid inlet end of the mixing glue head 153, so that the glue transported by the first glue supply tube 151 and the second glue supply tube 152 is fully mixed in the mixing glue head 153 (such as AB glue) and then transported to the glue outlet nozzle 155 through the glue injection tube 154.

[0085] In some embodiments, Figure 8As shown, in order to assist in guiding the glue nozzle 155 to position the glue coating scraper, the glue coating device 10 also includes a visual positioning component 160, which is connected to the support frame 140. The visual positioning component 160 includes a camera module 161 and a light source module 162.

[0087] The present invention also provides a battery pack processing device, such as Fig. 9 As shown, it includes the gluing device 10 of Example 1 and a manipulator 20, the manipulator 20 has a fixed end and a movable end, and the gluing device 10 is installed at the movable end of the manipulator 20; wherein, the manipulator 20 can drive the gluing device 10 to move along the Y direction to achieve gluing and scraping, thereby improving the automation capability and gluing efficiency.

[0088] In some embodiments, the battery pack processing equipment also includes a controller, and the driving component 121, the glue injection assembly 150 and the robot 20 are all electrically connected to the controller; wherein the controller is configured as follows: the controller can control the glue injection assembly 150 to stop supplying glue 0.5s-2s before the end of the glue injection; and after the glue injection assembly 150 stops supplying glue, after a preset time interval, the controller can also control the driving assembly 120 to drive the scraper plate 131 to move along the Z direction, so that the scraper plate 131 cooperates with the glue outlet nozzle 155 and removes the excess glue at the glue outlet nozzle 155.

[0089] The working process of the present invention is as follows: Figure 1-Figure 9As shown, when applying glue, the manipulator 20 drives the glue applying device 10 to move to the surface of the box body 30 to be coated with glue, and the visual positioning component 160 assists in guiding the glue nozzle 155 to position the glue coating and scraping position, and the driving member 121 drives the scraper plate 131 to approach the bottom surface of the box body 30 along the Z direction until the roller 132 abuts against the bottom surface of the box body 30, and the elastic member 113 is in a compressed state, and the driving member 121 is locked. On the bottom surface of the box body 30 with poor flatness, the roller 132 is always in contact with the product surface under the action of the elastic member 113. Specifically, when the bottom surface of the box body 30 is flat, the roller 132 rolls on the bottom surface of the box body 30, and the scraper plate 131 abuts against the bottom surface of the box body 30 that is higher than the bottom surface. The glue on the bottom edge of the scraper 131 is scraped off; when a convex area appears on the bottom surface of the box body 30, the roller 132 is pressed upward by the convex area, and the floating frame 115 moves upward along the guide rail 117 in the Z direction as a whole, and the elastic member 113 is further compressed. At this time, the roller 132 is still in contact with the bottom surface of the box body 30, thereby ensuring that the thickness of the glue layer is consistent with that when the bottom surface of the box body 30 is flat; when a concave area appears on the bottom surface of the box body 30, under the action of the elastic member 113, the roller 132 is pressed down to the concave area, thereby still keeping the roller 132 in contact with the bottom surface of the box body 30 in the concave area, ensuring that the thickness of the glue layer is consistent with the previous one, and avoiding the phenomenon of insufficient glue, glue accumulation, etc.

[0090] The glue A and glue B are respectively conveyed to the mixing glue head 153 through the first glue supply pipe 151 and the second glue supply pipe 152 by the glue pump to be fully mixed to form AB glue. The mixed AB glue is conveyed to the glue outlet nozzle 155 through the glue injection pipe 154, and the glue is squeezed out to the bottom surface of the box body 30. Then the robot 20 drives the scraper assembly 130 to move along the Y direction to realize synchronous glue injection and scraping. Since the floating assembly 110 has a certain distance of floating amount in the Z direction, it can match products with poor flatness; the controller can control the glue injection assembly 150 to stop supplying glue 0.5s-2s before the end of glue injection; and after the glue injection assembly 150 stops supplying glue, after a preset time interval, for example 0.3s-1s, the controller can also control the driving assembly 120 to drive the scraper plate 131 to move along the Z direction, so that the scraper plate 131 and the glue outlet nozzle 155 cooperates with and removes the excess glue at the glue outlet nozzle 155; specifically, taking the cylinder as an example of the driving member 121, the glue coating device 10 of the present invention coats glue and scrapes glue simultaneously. During this process, the cylinder extends a preset amplitude, and in the Z direction, the first bottom edge 133a of the scraper plate 131 is lower than the bottom edge of the glue outlet nozzle 155, so that the glue coming out of the glue outlet nozzle 155 can be scraped flat; when one gluing is completed, the robot 20 brings the glue coating device 10 back to the working starting point of the equipment, and a waste glue box is provided at the starting point. In order to prevent the glue at the glue outlet nozzle 155 from solidifying or gathering at the bottom edge of the glue outlet nozzle 155, the first abutting surface 133 of the scraper plate 131 and the second abutting surface 155a of the glue outlet nozzle 155 are tightly attached in the Y direction, and the cylinder contracts to form a "scissor-type" dislocation, and the glue on the glue outlet nozzle 155 falls off. In addition, when the cylinder retracts, the rollers 132 on both sides are also retracted synchronously, so that the bottom edge of the glue outlet nozzle 155 is in an open state, which is convenient for the glue cleaning / wiping function of the original equipment, and regularly completes glue cleaning and glue discharge to ensure that the glue liquid is not solidified and the glue outlet nozzle 155 is not blocked.

[0091] In summary, the present invention can drive the scraper 131 to move in the Z direction by setting the driving member 121, so as to ensure that the distance between the scraper 131 and the surface to be coated with glue is quantified, and the thickness of the glue layer after scraping glue is ensured to be relatively uniform, and the scraper 131 is located on the side of the glue outlet nozzle 155 in the Y direction. When coating glue, the scraper 131 can move along the Y direction and spread the glue, so as to avoid the phenomenon of glue shortage while ensuring the thickness of the glue layer; in addition, after the gluing is completed, the driving member 121 can drive the scraper 131 to move along the Z direction, so as to remove the residual glue at the glue outlet nozzle 155, realize automatic cleaning of the glue nozzle, and do not need manual cleaning, thereby improving the gluing efficiency and preventing the residual glue from accidentally falling into the coated area.
