Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of quick assembly and disassembly, in particular to a micro concave coating head glue tank based on a quick assembly and disassembly structure. BACKGROUND

[0002] The micro concave coating head is a precision component commonly used in coating processes and is widely used in fields such as lithium battery production, optical film coating, and adhesive tape manufacturing. Its function is to uniformly coat glue or other coating materials on a substrate, and the glue tank is an important component of the micro concave coating head, which is responsible for storing and supplying glue to ensure the continuity and stability of the coating process.

[0003] The existing glue tank usually adopts an integrated molding design. Although this design has the advantages of simple structure and convenient manufacturing, it has some problems that cannot be ignored in actual use, especially in cleaning. The internal structure of the glue tank with integrated molding design is often complex, with many small gaps and corners. These places are prone to accumulate glue residues, solidified substances, and other impurities during long-term use.

[0048] The limiting piece 22 comprises a supporting block 221 slidingly arranged on the upper surface of the sliding block along the front-rear direction, three trapezoidal clamping blocks 222 distributed along the front-rear direction are fixedly connected to one side of the supporting block 221 close to the material blocking plate 12, the front and rear sidewalls of the trapezoidal clamping block 222 are both fixedly connected with elastic top plates, two pushing blocks 223 distributed along the front-rear direction and fixedly provided with blocking plates on the outer sidewalls are fixedly arranged at the other end of the supporting block 221, and the end of the pushing block 223 away from the supporting block 221 slidingly penetrates the mounting cavity 21.

[0049] The interior of the material containing bin 11 is rotationally provided with three stirring rollers distributed along the left-right direction and one end connected with an external driving piece, the circumferential outer walls of the three stirring rollers are respectively provided with a plurality of cams 115 abutting the upper surface of the sieve plate 111 along the front-rear direction, the cams 115 arranged on adjacent stirring rollers are arranged in a staggered manner, and the front and rear sidewalls of the material containing bin 11 are both provided with a linkage group 116 which can be used to realize the synchronous approach or departure of the two supporting blocks 221.

[0050] The linkage group 116 comprises an L-shaped sealing plate 1161 rotationally arranged on the sidewall of the material containing bin 11 through a torsion spring, a driving bevel gear is rotationally arranged in the interior of the sealing plate 1161 along the axial direction, and linkage pieces are arranged in the interior of the sealing plate 1161 and located at the left and right ends of the driving bevel gear.

[0051] The linkage member comprises a driven bevel gear arranged inside the cover plate 1161 through a threaded rod 1162 and always in meshing transmission with the driving bevel gear, and the threaded rod 1162 is threadedly connected with a linkage block 1163 in a U shape and used for driving the supporting block 221 to move.

[0052] Specifically, during the quick installation of the material blocking plate 12:

[0053] Firstly, the material blocking plate 12 is moved between the two installation cavities 21 and the left and right ends of the material blocking plate 12 are aligned with the side walls of the two installation cavities 21 (in the initial state, since the material containing bin 11 and the material blocking plate 12 are in a separated state, the material blocking plate 12 needs to be pushed into the two installation cavities 21 to complete the assembly of the whole glue tank body 1), and then the material blocking plate 12 is pushed and slid into the two installation cavities 21 in the front and back directions (the upper surface of the material blocking plate 12 is provided with a sieve plate 111 through a plurality of return springs, so that during the pushing process of the material blocking plate 12, the sieve plate 111 is preferentially contacted with the material containing bin 11, and the height of the sieve plate 111 is lowered through the chamfer formed on the sieve plate 111 and the compression of the return spring of the material containing bin 11 during the contacting process), when the material blocking plate 12 and the sieve plate 111 are moved to the predetermined position, since the compression forces on the front and back ends of the return spring under the sieve plate 111 disappear, the return spring quickly releases the elastic potential energy stored therein, drives the sieve plate 111 to perform a rebound movement, and finally makes the upper surface of the rebounded sieve plate 111 abut against the outer wall of the cam 115 fixedly connected with the outer wall of the stirring roller, during this process, the sieve plate 111 is pushed into the material containing bin 11, which ensures that the position between the material containing bin 11 and the material blocking plate 12 will not be dislocated due to the excessive or insufficient force applied during the pushing process of the material blocking plate 12, the automatic return of the sieve plate 111 is realized through the return spring, which effectively avoids the problems caused by unstable operation force, and further improves the stability and reliability of the equipment under the premise of ensuring the accurate positioning between the two.

[0054] When the material blocking plate 12 reaches the predetermined position and completes the preliminary positioning, the cover plates 1161 on the front and back side walls of the material containing bin 11 are simultaneously controlled to be turned down by ninety degrees, and with the turning movement of the cover plates 1161, the side walls and the lower ends thereof will gradually move and abut against the side walls and the lower surface of the material blocking plate 12, respectively, thereby completing the supporting work of the front and back ends of the material blocking plate 12 (the two cover plates 1161 are arranged in an L shape and are respectively installed on the side walls of the material containing bin 11, in the initial state, the side wall close to the vertical segments of the two cover plates 1161 is fixedly provided with an elastic abutting member, the design purpose of which is that with the turning movement of the cover plates 1161, the elastic abutting member will be blocked by the material blocking plate 12 and be compressed and deformed, and with the gradual compression of the elastic abutting member, the abutting force of the elastic abutting member on the front and back lower surfaces of the material blocking plate 12 will be further improved).

[0055] Specifically, when the sealing plate 1161 is flipped around its rotation shaft, its vertical section will gradually approach the material storage bin 11, at this time, the elastic abutting member fixed on the vertical section of the sealing plate 1161 will be in contact with the lower surface of the material blocking plate 12, and will be gradually compressed as the sealing plate 1161 is flipped, due to the elastic property of the elastic abutting member, an opposite force will be generated during its compression process, which will act on the lower surface of the material blocking plate 12, thereby generating an upward abutting force on the material blocking plate 12, as the flipping angle of the sealing plate 1161 increases, the compression amount of the elastic abutting member also increases, and the abutting force of the elastic abutting member on the material blocking plate 12 also increases, through the setting of the elastic abutting member, it is ensured that the material blocking plate 12 can maintain a stable position when subjected to material pressure or other external forces, and deviation or tilting is avoided, at the same time, due to the existence of the elastic abutting member, the connection between the material blocking plate 12 and the sealing plate 1161 is also more firm, thereby improving the reliability and stability of the entire device, at the same time, when the two sealing plates 1161 are synchronously flipped, the U-shaped linkage block 1163 on the same sealing plate 1161 is also synchronously clamped into the two ends of the bearing block 221 inside the installation cavity 21.

[0056] Subsequently, the electric tool is used to drive the internal driving bevel gears (not shown in the drawings) of the front and rear sealing plates 1161 to rotate synchronously. Taking any sealing plate 1161 as an example, the driving bevel gears mesh with the left and right driven bevel gears (not shown in the drawings) to drive them to rotate during the rotation process. The two driven bevel gears drive the corresponding linkage blocks 1163 to move through the threaded rods 1162 during the rotation process, and the abutting work of the supporting block 221 and the material blocking plate 12 is completed during the movement of the linkage block 1163 (after the sealing plate 1161 completes the flipping action, the supporting block 221 is accurately clamped into the internal space of the linkage block 1163, and the linkage block 1163 will synchronously drive the supporting block 221 to move along the installation cavity 21 with the rotation of the threaded rod 1162. During the movement of the supporting block 221, the trapezoidal clamping block 222 will enter the internal space of the corresponding locking groove 121, and through the cooperation of the trapezoidal clamping block 222 and the elastic top plate connected thereto, the abutting and limiting functions of the material blocking plate 12 in the left and right directions are realized. Specifically, when the supporting block 221 moves under the drive of the linkage block 1163, the trapezoidal clamping block 222 arranged thereon will slide along the guide surface of the locking groove 121 and finally enter the internal space of the locking groove 121. Due to the special shape of the trapezoidal clamping block 222, it will be constrained by the side surface of the locking groove 121 after entering the locking groove 121, thereby extruding the elastic top plate and causing the elastic top plate to retract. Through the reaction force of the elastic top plate, the material blocking plate 12 is abutted and pushed, thereby realizing the abutting of the material blocking plate 12. At the same time, in order to ensure the stable support of the material blocking plate 12, the supporting block 221 also drives the support plate 211 to slide through the linkage of the sliding block and the strip-shaped block during the movement process. The upper surface of the support plate 211 is in close contact with the lower surface of the material blocking plate 12 during the sliding process, thereby realizing the effective support of the lower surface of the material blocking plate 12.

[0057] During the injection of the glue into the glue groove body 1, the glue will generate a certain pressure on the material blocking plate 12, trying to push it away. However, through the cooperation of the sealing plate 1161, the elastic abutting element, the trapezoidal clamping block 222, and the support plate 211, multi-directional support and abutting of the material blocking plate 12 are realized, ensuring that the material blocking plate 12 can remain stable during the subsequent glue injection process and avoiding shaking or falling due to the action of the glue pressure.

[0058] Specifically, after the completion of the turnover, the elastic abutting part provided on the sealing plate 1161 will be in close contact with the material blocking plate 12, providing an initial abutting force. With the rotation of the threaded rod 1162, the linkage block 1163 drives the supporting block 221 to move, and the trapezoidal clamping block 222 enters the locking groove 121. Through the special geometric shape and the effect of the elastic top plate, the abutting force of the material blocking plate 12 in the left-right direction is further enhanced. At the same time, the upper surface of the supporting plate 211 closely adheres to the lower surface of the material blocking plate 12 under the drive of the sliding block and the strip-shaped block, providing a vertical supporting force. This multidirectional supporting and abutting mechanism can effectively resist the pressure generated during the injection of glue. Since the material blocking plate 12 is constrained in the left-right direction by the elastic abutting part and the trapezoidal clamping block 222, and is supported in the vertical direction by the supporting plate 211, it can maintain a stable position during work and will not shake or fall off.

[0059] Installation of the filter plate 112 and use of the glue tank body 1:

[0060] When the material blocking plate 12 completes the limiting work, two filter plates 112 are inserted into the material blocking plate 12 from above the material storage bin 11 in an opposite manner, and the two filter plates 112 are respectively electromagnetically fixed with the material blocking plate 12 (the side of each filter plate 112 close to the inner side wall of the material storage bin 11 is provided with a plurality of scraping knives 113 in the up-down direction. When the filter plate 112 is inserted into the material blocking plate 12 in the vertical direction, the blade of the scraping knife 113 is ensured to be in close contact with the inner side wall of the material storage bin 11, to ensure the smooth progress of the later scraping work). After the installation of the two filter plates 112 is completed, glue is injected into the inside of the material storage bin 11. Since the two cleaning scrapers 1143 are provided with floaters 1144 below, the two cleaning scrapers 1143 will not sink into the glue when the injection of glue is completed.

[0061] When the glue tank body 1 performs the coating operation, the three stirring rollers arranged inside the storage bin 11 rotate synchronously under the power provided by the external driving member. This rotating movement not only effectively prevents the glue inside the glue tank body 1 from solidifying due to static, maintains the continuous flow state of the glue, but also realizes the intermittent pushing of the sieve plate 111 through the synchronous rotation of the several cams 115 uniformly distributed on the outer wall of the stirring roller. The sieve plate 111 moves downward under the pushing action of the cams 115, and the linkage rod 1223 is also pushed synchronously. The several poking rods 1224 arranged on the outer wall of the linkage rod 1223 slide along the sawtooth-shaped groove. The precise cooperation between the poking rods 1224 and the sawtooth-shaped groove drives the rotation of the mounting sleeve 1221 and the stirring paddle 1222 fixedly connected thereto. Through the rotating movement of the stirring paddle 1222 mounted on the outer wall of the sleeve, the glue at the bottom of the glue tank body 1 is effectively stirred. This stirring action is complementary to the rotating movement of the three stirring rollers, further improving the stirring effect of the glue inside the glue tank body 1, and ensuring the uniformity and fluidity of the glue.

[0062] It should be noted that since the two filter plates 112 with the material scraping knives 113 arranged on the side walls are fixed on the sieve plate 111 by magnetic connection, when the sieve plate 111 reciprocates up and down, the material scraping knives 113 can effectively perform scraping operation on the inner side wall of the storage bin 11. This design aims to eliminate the dead angle that may exist during stirring, prevent the adhesion and accumulation of glue on the inner wall of the storage bin 11. Specifically, the up-and-down reciprocating movement of the sieve plate 111 drives the synchronous movement of the filter plate 112 magnetically connected thereto. The material scraping knives 113 arranged on the side walls of the filter plate 112 are in close contact with the inner wall of the storage bin 11 during movement, thereby scraping off the glue adhered to the wall surface. This scraping action not only avoids the adhesion of glue on the inner wall of the storage bin 11, but also prevents the decrease of stirring efficiency and the potential risk of pollution caused by glue accumulation.

[0063] When the coating work is carried out, some impurities or oily materials inevitably pollute the glue. At this time, the two installation rods 1141 are driven by the external driving member to slide along the guide groove 1121, and the two cleaning scrapers 1143 are driven to move. Since the two cleaning scrapers 1143 are provided with cylindrical floats 1144 below, the scrapers can always float on the upper surface of the glue in the glue tank body 1. During the movement of the cleaning scrapers 1143 on the surface of the glue, the floating impurities and oily substances are effectively collected. With the continuous movement of the installation rods 1141 along the guide groove 1121, the height of the guide groove 1121 gradually increases, and the two cleaning scrapers 1143 are gradually lifted and finally separated from the glue tank body 1. Since the two cleaning scrapers 1143 are connected to the sliding blocks in a rotating manner, and the lower surfaces of the scrapers are connected to counterweights, the scrapers can still maintain a balanced state even after being separated from the glue, avoiding overturning or turning over. When the installation rods 1141 move to the last end of the guide groove 1121, the cleaning scrapers 1143 cooperate with the external top plate to trigger the rotation of the scrapers. Through the cooperation of the guide groove 1121 and the installation rod 1141, the continuous collection and automatic cleaning of the impurities and oily substances on the surface of the glue by the cleaning scrapers 1143 are realized. The design of the float 1144 of the cleaning scraper 1143 ensures that it is always located on the surface of the glue, and the use of the counterweight ensures the stability of the scraper after it is separated from the glue. The variable height design of the guide groove 1121 realizes the automatic lifting and separation of the scraper. Finally, through the cooperation with the external top plate, the rotation of the scraper and the automatic falling of the impurities into the collection box realize the automatic cleaning and collection of the impurities.

[0064] It should be noted that the cleaning scraper 1143 is slidably arranged in the elliptical groove of the waist-shaped block 1142 by the sliding block, which is to adapt to the change of the height of the glue in the glue tank body 1.

[0065] Quick disassembly work of the material blocking plate 12:

[0066] When the glue tank body 1 needs to be cleaned, the driving bevel gears inside the front and rear side sealing plates 1161 are driven to rotate by the electric tool, the driven bevel gears on both sides are driven to rotate by the driving bevel gears, and the support block 221 and the support plate 211 are driven away from the material blocking plate 12 by the linkage block 1163 during the rotation of the driven bevel gears. Then, the two side sealing plates 1161 are flipped to the initial position, and finally the material blocking plate 12 without abutting and supporting is taken out downward.

[0067] It should be noted that the glue tank body 1 adopts a separable structure, and is divided into a material containing bin 11 and a material blocking plate 12. This not only facilitates assembly and disassembly and maintenance, but also makes the material containing bin 11 and the material blocking plate 12 easier to clean, effectively avoids the accumulation of residual materials, and reduces the risk of pollution.

[0068] The glue tank body 1 adopts a modular design, realizes a separable structure, and is divided into two independent modules of the material containing bin 11 and the material blocking plate 12. Not only is the maintainability and dismountability of the equipment significantly improved, but also the cleaning work of the material containing bin 11 and the material blocking plate 12 is simplified. Specifically, the modular design of the material containing bin 11 and the material blocking plate 12 enables maintenance personnel to quickly and conveniently dismount and assemble the equipment, thereby shortening the maintenance time and reducing the maintenance cost. Meanwhile, the detachable design makes the material containing bin 11 and the material blocking plate 12 easier to be thoroughly cleaned, which can effectively avoid the accumulation of residual materials in the equipment. The accumulation of residual materials not only affects the quality and coating effect of the glue, but also may increase the pollution risk and even cause equipment failure.

[0069] It is worth emphasizing that the glue tank of the micro-concave coating head based on the quick mounting and dismounting structure mainly has the following advantages:

[0070] Advantage one, the glue tank body 1 adopts a modular design, realizes a separable structure, and is divided into two independent modules of the material containing bin 11 and the material blocking plate 12. Not only is the maintainability and dismountability of the equipment significantly improved, but also the cleaning work of the material containing bin 11 and the material blocking plate 12 is simplified. Specifically, the modular design of the material containing bin 11 and the material blocking plate 12 enables maintenance personnel to quickly and conveniently dismount and assemble the equipment, thereby shortening the maintenance time and reducing the maintenance cost. Meanwhile, the detachable design makes the material containing bin 11 and the material blocking plate 12 easier to be thoroughly cleaned, which can effectively avoid the accumulation of residual materials in the equipment. The accumulation of residual materials not only affects the quality and coating effect of the glue, but also may increase the pollution risk and even cause equipment failure.

[0071] The three stirring rollers arranged in the interior of the container 11 rotate synchronously under the power provided by the external driving member, maintaining the continuous flow state of the glue. The intermittent pushing of the sieve plate 111 is realized by the synchronous rotation of the several cams 115 evenly distributed on the outer wall of the stirring roller. The sieve plate 111 and the linkage rod 1223 move downward under the pushing action of the cams 115. The several push rods 1224 slide along the zigzag-shaped slot and then drive the rotation of the mounting sleeve 1221 and the stirring paddle 1222 fixedly connected thereto, finally completing the effective stirring of the stirring paddle 1222 on the glue at the bottom of the glue tank body 1. At the same time, when the sieve plate 111 reciprocates up and down, the scraping knife 113 can effectively scrape the inner side wall of the container 11, eliminating the dead angle that may exist during stirring and preventing the adhesion and accumulation of glue on the inner wall of the container 11. The scraping knife 113 arranged on the side wall of the filter plate 112 is in close contact with the inner wall of the container 11 during movement, thereby scraping off the glue that may adhere to the wall surface. This not only avoids the adhesion of glue on the inner wall of the container 11, but also prevents the decrease of stirring efficiency and the potential pollution risk caused by the accumulation of glue.

[0072] The third advantage is that when the supporting block 221 moves under the driving of the linkage block 1163, due to the special shape of the trapezoidal clamping block 222, it will be constrained by the side of the locking groove 121 after entering the locking groove 121, thereby extruding the elastic top plate and causing the elastic top plate to retract. The elastic top plate pushes against the side of the blocking plate 12 through the reaction force, thereby realizing the tight pressing of the blocking plate 12. At the same time, in order to ensure the stable support of the blocking plate 12, the supporting block 221 also drives the support plate 211 to slide through the linkage of the sliding block and the strip-shaped block during movement, and the upper surface of the support plate 211 is in close contact with the lower surface of the blocking plate 12 during sliding, thereby realizing the effective support of the lower surface of the blocking plate 12.

[0073] The fourth advantage is that the two installation rods 1141 are driven to slide along the guide grooves 1121, and the two cleaning scrapers 1143 are driven to move, and because the two cleaning scrapers 1143 are provided with the cylindrical floaters 1144 below, the scrapers can always float on the upper surface of the glue in the glue tank body 1, and the cleaning scrapers 1143 can effectively collect the floating impurities and oily substances during the movement on the glue surface, and as the installation rods 1141 continuously move backward along the guide grooves 1121, the height of the guide grooves 1121 gradually increases, and the two cleaning scrapers 1143 are gradually lifted up and finally separated from the glue tank body 1, and because the two cleaning scrapers 1143 are connected with the sliding blocks in a rotating manner and the lower surfaces of the scrapers are respectively connected with the counterweights, the scrapers can still keep the balance even if they are separated from the glue, and the overturning or turning over is avoided, and when the installation rods 1141 move to the last end of the guide grooves 1121, the cleaning scrapers 1143 cooperate with the external top plate to trigger the rotation of the scrapers, and through the cooperation of the guide grooves 1121 and the installation rods 1141, the continuous collection and automatic cleaning of the impurities and oily substances on the glue surface by the cleaning scrapers 1143 are realized.
