[0002] The main function of brushes in DC motors is to connect and conduct current between the plug and the brushes, ensuring that the brushes contact the commutator at the correct contact angle and providing appropriate pressure to the brushes so that they contact the commutator surface with a certain pressure, thereby ensuring that the current can be smoothly conducted through the plug, brushes, and brushes to the commutator.

[0003] Traditional production processes involve manual or semi-automatic cutting, drilling, and riveting by workers, resulting in low production efficiency, unstable product quality, low product qualification rate, and high labor costs. This fails to meet the demand for standardized, mechanized, and large-scale production of brush assemblies. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide an automatic adhesive applicator for brush pads. This device can automatically apply adhesive to brush pad assemblies after stamping and shaping, and then return and inspect the finished products after adhesive application, effectively ensuring a high yield rate. The entire process is highly automated and precise, requires no manual labor, saves time and effort, ensures production quality, reduces production costs, and improves production efficiency.

The first stamping baffle protrudes to form a second inclined stamping surface that matches the first inclined stamping surface. The first stamping and shaping drive motor drives the first stamping column to press against the first stamping baffle. The first inclined stamping surface of the first stamping column abuts against the connecting end, and the other side of the connecting end abuts against the second inclined stamping surface, thus stamping and bending the connecting end until the inclined and suspended end on the brush body becomes an angle parallel to the first stamping and shaping drive motor.

[0012] As a further improvement of this utility model, the first stamping and shaping device further includes a first stamping and shaping first limiting plate disposed on the output shaft of the first stamping and shaping drive motor, at least one first stamping and shaping telescopic column disposed at one end on the side of the first stamping and shaping first limiting plate, a first stamping and shaping spring sleeved on the first stamping and shaping telescopic column, and a first stamping and shaping second limiting plate disposed at the other end of the first stamping and shaping telescopic column; one end of the first stamping column away from the first inclined stamping surface is disposed on the first stamping and shaping first limiting plate, and the other end passes through the first stamping and shaping second limiting plate to stamp and deform the connecting end.

[0016] The beneficial effects of this utility model are as follows:

[0017] By configuring this automatic adhesive granule applicator to include a brush assembly, the brush assembly includes a terminal connected as a whole strip and a brush body disposed on the terminal, and also includes a first stamping and shaping device, an adhesive granule feeding device, and a second stamping and shaping device mounted on a platform.

The suction and cutting assembly includes a suction and cutting bracket mounted on the platform, a cutting drive motor disposed on the suction and cutting bracket, a cutting column disposed on the output shaft of the cutting drive motor, and a cutting plate disposed on the suction and cutting bracket and penetrated by the cutting column. The cutting plate has a cutting opening in the middle for the cutting column to pass through, and the upper end of the cutting plate also has a roll feed port for the adhesive granule roll to extend into and downward into the cutting opening.

[0018] The brush plate assembly is first conveyed to the first stamping and shaping device by an external conveying mechanism. The first stamping and shaping device stamps the terminals to deform them to a suitable angle for adhesive application on the brush plate body. The entire adhesive roll is wound onto the roll assembly, which then winds up and stores the adhesive roll. In use, the adhesive roll is pulled from the roll assembly, the backing paper is peeled off, and it is fed into the adhesive feeding port, allowing the adhesive roll to enter the position directly opposite the cutting edge. Then, the stamped and deformed brush plate body is conveyed to the suction and cutting assembly positioned directly opposite the cutting edge. The brush plate assembly enters the suction and cutting assembly directly opposite the cutting edge. At the punching cut, the punching drive motor starts and drives the punching column mounted on its output shaft to move towards the punching cut. As the punching column passes through the punching cut, it cuts the roll of rubber granules into rubber granules of appropriate size and punches them onto the brush body, completing the assembly of the brush assembly. The assembled brush assembly is then conveyed to the second stamping and shaping device, where the terminals are stamped to their initial state, facilitating the subsequent assembly of the brush assembly into the motor. The entire process is highly automated and precise, requires no manual labor, saves time and effort, ensures production quality, reduces production costs, and improves production efficiency.

[0040] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods of this utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] Please refer to Figures 1 to 15 This utility model provides an automatic adhesive granule applicator for brush sheets, including a brush sheet assembly 1. The brush sheet assembly 1 includes a terminal 11 connected as a whole strip and a brush sheet body 12 disposed on the terminal 11. It also includes a first stamping and shaping device 2, an adhesive granule feeding device 3, and a second stamping and shaping device 4 mounted on a platform. The adhesive granule feeding device 3 includes a suction and cutting assembly 31 mounted on the platform and a roll assembly 32 disposed on the suction and cutting assembly 31. The cutting assembly 31 includes a suction and punching bracket 311 mounted on a platform, a punching drive motor 312 mounted on the suction and punching bracket 311, a punching column 313 mounted on the output shaft of the punching drive motor 312, and a punching plate 314 mounted on the suction and punching bracket 311 and penetrated by the punching column 313. The punching plate 314 has a punching opening 3141 in the middle for the punching column 313 to pass through, and a roll of rubber feed port 3142 is formed at the upper end of the punching plate 314 for the rubber granules to extend into and downward into the punching opening 3141.

[0045] The brush assembly 1 is first conveyed to the first stamping and shaping device 2 by an external conveying mechanism. The first stamping and shaping device 2 stamps the terminal 11 to deform it to a suitable angle for adhesive application on the brush body 12. The entire roll of adhesive granules is wound onto the roll assembly 32, which rolls up and stores the roll of adhesive granules. In use, the roll of adhesive granules is pulled out from the roll assembly 32, the backing paper is peeled off, and then it is fed into the adhesive feeding port 3142, so that the roll of adhesive granules enters from the adhesive feeding port 3142 to the position directly opposite the cutting opening 3141. Then, the stamped and deformed brush body 12 is conveyed to the suction and cutting assembly 31, which is positioned directly opposite the cutting opening 3141. The brush assembly 1 then enters the suction and cutting assembly. The component 31 is positioned opposite the punching opening 3141. The punching drive motor 312 starts and drives the punching column 313, which is mounted on its output shaft, to move towards the punching opening 3141. As the punching column 313 passes through the punching opening 3141, it cuts the roll of rubber granules inside into rubber granules of appropriate size and punches them onto the brush body 12, completing the assembly of the brush assembly with adhesive. The assembled brush assembly 1 is then conveyed to the second stamping and shaping device 4, where the second stamping and shaping device 4 punches the terminals 11 to their initial state, facilitating the subsequent assembly of the brush assembly 1 into the motor. The entire process is highly automated and precise, requires no manual labor, saves time and effort, ensures production quality, reduces production costs, and improves production efficiency.

[0046] Regarding the specific structural configuration of the brush assembly 1, as follows: Figure 2 and Figure 3 As shown, the terminal 11 includes a connecting piece 111 that is connected into a strip shape and a connecting end 112 that is T-shaped and disposed on the connecting piece 111. The brush body 12 is V-shaped, with one side of the V-shape disposed on the horizontal part of the connecting end 112 and the other side tilted and suspended. Several through holes 1111 for through fixing are arranged on the connecting piece 111.

[0047] To ensure the cut adhesive particles adhere more precisely to the brush plate body 12, such as Figure 9As shown, the suction and punching assembly 31 also includes a suction motor 315 disposed at one end of the punching column 313 near the punching drive motor 312. The middle part of the punching column 313 has at least one suction port 3131 connected to the suction motor 315. When the punching drive motor 312 drives the punching column 313 forward, the suction motor 315 starts at the same time to generate suction, so that the cut rubber particles are adsorbed on the suction port 3131 and punched and pasted onto the brush plate body 12 by the punching column 313. By adsorbing the cut rubber particles through the suction port 3131, the position of the rubber particles is fixed, effectively preventing the rubber particles from shifting or falling off, so that the cut rubber particles are more accurately pasted onto the brush plate body 12, and improving the assembly accuracy of this rubber particle feeding device 3.

[0048] Preferred, such as Figure 9 As shown, the number of suction ports 3131 is three sets evenly distributed within the punching column 313, thereby making its adsorption force on the adhesive particles more uniform and more conducive to making the cut adhesive particles more accurately adhere to the brush plate body 12.

[0049] The size of the rubber particles cut by the punching column 313 can be set according to the actual situation, so no specific limitation is made in this embodiment.

[0050] For other structural settings of this suction punching clamp, such as Figures 7 to 8 , Figure 10 As shown, the suction and punching assembly 31 further includes a granule punching first limiting plate 316 disposed on the output shaft of the punching drive motor 312, a granule punching pressure plate 317 disposed on one end of the suction and punching bracket 311 away from the punching drive motor 312, and a winding structure 318 disposed on the other end of the suction and punching bracket 311 away from the punching drive motor 312. The punching column 313 and the suction motor 315 are disposed on the punching first limiting plate, thereby realizing the purpose of the punching drive motor 312 driving the punching column 313 and the suction motor 315 to push and retract through the granule punching first limiting plate 316. By setting the granule stamping pressure plate 317, the brush assembly 1 is conveyed to the granule stamping pressure plate 317 by an external conveying mechanism for processing. The granule stamping pressure plate 317 slides and limits the brush assembly 1, thereby preventing the brush assembly 1 from shifting or falling off during processing, further improving the assembly accuracy of this granule feeding device 3. By setting the winding structure 318, the cut scraps are recycled, reducing the accumulation of scraps that could cause the suction and punching assembly 31 to malfunction.

[0051] Regarding the connection method of the first limiting plate 316 for the granule stamping and the punching plate 314, as follows: Figures 7 to 8 , Figure 10As shown, a granule-stamping telescopic column and a granule-stamping spring correspondingly sleeved on the granule-stamping telescopic column are also provided between the granule-stamping first limiting plate 316 and the punching plate 314. When the punching drive motor 312 starts, it drives the granule-stamping first limiting plate 316 forward. The granule-stamping telescopic column on the granule-stamping first limiting plate 316 simultaneously drives the punching plate 314 on it forward, so that the punching plate 314 presses against the granule-stamping first limiting plate 316 to fix and limit the brush assembly 1. The punching drive motor 312 continues to... When pushed, the granule stamping telescopic column locks, the granule stamping spring is compressed for buffering, and the punching plate 314 is driven to continue advancing, thereby driving the punching column 313 to extend into the punching opening 3141 to cut the granule roll and attach the granules to the brush body 12. By setting the granule stamping telescopic column and the granule stamping spring correspondingly sleeved on the granule stamping telescopic column, the pressure on the punching drive motor 312 is buffered, effectively reducing the impact force on the brush body 12 and preventing damage to the brush body 12 due to instantaneous impact force.

[0052] The specific structural configuration of the winding structure 318 is as follows: Figure 7 As shown, the winding structure 318 includes a winding reel 3181 disposed on the other end of the suction and punching bracket 311 away from the punching drive motor 312, a winding motor 3182 disposed at the rear end of the winding reel 3181, a winding limiting bracket 3183 connected to the output shaft of the winding motor 3182, a main winding reel 3184 disposed on the winding limiting bracket 3183 and connected to the output shaft of the winding motor 3182, a secondary winding reel 3185 disposed on the winding limiting bracket 3183, and a storage reel 3186 mounted on the platform. Preferably, the lower end of the suction and punching bracket 311 has a recycling hole for the cut scraps to pass through and be recycled. The cut scrap material emerges from the lower end of the roll feed port 3142, is adjusted by the take-up shaft 3181, and enters between the main take-up shaft 3184 and the secondary take-up shaft 3185. The take-up motor 3182 drives the main take-up shaft 3184 to rotate, and the secondary take-up shaft 3185 is also driven to rotate, thereby limiting the forward movement of the cut scrap material and providing it with forward propulsion. Finally, the cut scrap material is collected in the receiving shaft 3186. Preferably, a motor is also provided on one side of the receiving shaft 3186 to drive the receiving shaft 3186 to complete the collection of the cut scrap material.

[0053] The specific method by which the rubber particle stamping pressure plate 317 limits the position of the brush assembly 1 is as follows: Figure 8 , Figure 10As shown, the end of the granule stamping pressure plate 317 facing the punching column 313 has a brush plate sliding groove for sliding and limiting the brush plate body 12, and a terminal sliding groove disposed at the lower end of the brush plate sliding groove for sliding and limiting the terminal 11. The external conveying mechanism places the brush plate body 12 of the brush plate assembly 1 into the brush plate sliding groove for sliding, and the terminal 11 into the terminal sliding groove for sliding, thereby limiting the brush plate assembly 1 and preventing the brush plate assembly 1 from shifting or falling off during movement, which would lead to the problem of inaccurate granule adhesion, and improving the assembly accuracy of this granule feeding device 3.

[0054] Regarding the specific method by which the punching plate 314 limits the position of the brush assembly 1, as follows: Figures 7 to 8 As shown, the end of the granule stamping pressure plate 317 facing the punching post 313 has at least one through groove that matches the through hole 1111. The end of the punching plate 314 facing the stamping pressure plate has at least one granule through post that can pass through the through groove and penetrate the through hole 1111. When the punching plate 314 is pressed in the direction of the granule stamping pressure plate 317, it cooperates with the speed at which the external conveying mechanism conveys the brush assembly 1, so that the granule through post on the punching plate 314 passes through the through groove and enters the through hole 1111 while being pushed forward, thereby positioning the terminal 11 and preventing the brush assembly 1 from shifting or falling off during the movement, which would cause the problem of inaccurate granule adhesion, thus improving the assembly accuracy of this granule feeding device 3.

[0055] To further improve the accuracy of adhesive particles adhering to the brush plate body 12, such as Figure 7As shown, the brush body 12 is V-shaped, with one side of the V-shape attached to the terminal 11 and the other end suspended and parallel to the punching plate 314. The suction punching assembly 31 also includes a brush fixing structure 319 mounted on the granule punching pressure plate 317. The brush fixing structure 319 includes a brush fixing guide rail 3191 mounted on the suction punching bracket 311, a brush fixing slider 3192 slidably mounted on the brush fixing guide rail 3191, and a brush fixing post 3193 mounted on the brush fixing slider 3192. The lower end of the brush fixing post 3193 forms a triangular prism that matches the V-shaped structure of the brush body 12. Preferably, a motor that can drive the brush fixing slider 3192 to slide downwards may also be mounted on the brush fixing slider 3192. After the external conveying mechanism conveys the brush assembly 1 into place, the brush fixing slider 3192 slides downward along the brush fixing guide rail 3191 under the drive of the motor, so that the brush fixing post 3193 set thereon is inserted into the V-shape of the brush body 12, thereby limiting the position of the brush body 12 and preventing the V-shaped brush body 12 from deforming during the stamping process, which would cause the glue particles to be inaccurately pasted.

[0056] Regarding the specific structural configuration of the roll assembly 32, as follows: Figure 7 As shown, the roll assembly 32 includes a roll support 321 mounted on the suction and punching assembly 31, at least one roll motor 322 mounted on the roll support 321, a roll spool 323 mounted on the output shaft of the roll motor 322, at least one roll auxiliary paper motor 324 mounted on the roll support 321, and a roll auxiliary paper spool 325 mounted on the roll auxiliary paper motor 324. The adhesive granules are wound on the roll spool 323. When needed, the roll motor 322 is started to release the adhesive granules wound on the roll spool 323. The released adhesive granules can be wound onto the roll auxiliary paper spool 325 after the auxiliary paper is peeled off by a robotic arm or manually. Subsequently, the roll auxiliary paper motor 324 can automatically peel off the subsequent auxiliary paper. The adhesive granules after the auxiliary paper is peeled off enter the punching opening 3141 for punching.

[0057] Preferred, such as Figure 7 As shown, multiple rollers for limiting the rolling of rubber granules can also be provided on the roll support 321, so that the rolling of rubber granules can be conveyed more accurately and smoothly.

[0058] Regarding the specific structural configuration of the first stamping and shaping device 2, as follows: Figures 4 to 6As shown, the first stamping and shaping device 2 includes a first stamping and shaping bracket 21 mounted on a platform, a first stamping and shaping drive motor 22 disposed on one end of the first stamping and shaping bracket 21, a first stamping column 23 disposed on the output shaft of the first stamping and shaping drive motor 22, and a first stamping baffle 24 disposed on the other end of the first stamping and shaping bracket 21. The front end of the first stamping column 23 forms a first inclined stamping surface 231 that matches the V-shaped angle of the brush body 12, and the first stamping baffle 24 protrudes to form a second inclined stamping surface 241 that matches the first inclined stamping surface 231.

[0059] During production, the external conveying mechanism places the terminal 11 of the brush assembly 1 between the first stamping baffle 24 and the first stamping column 23. At this time, the brush body 12 is V-shaped, with one side of the V-shape set on the terminal 11 and the other side tilted and suspended. The first stamping and shaping drive motor 22 starts, driving the first stamping column 23 to press against the first stamping baffle 24. The first tilted stamping surface 231 of the first stamping column 23 presses against one end of the connecting end 112 and continues to press in, so that the other side of the connecting end 112 presses against the second tilted stamping surface 241. The pressing continues until the connecting end 112 is stamped and bent until the tilted and suspended end of the brush body 12 becomes parallel to the motor, which facilitates the subsequent glue feeding device 3 to perform glue application and other processes. The whole process is highly automated and accurate, requires no manual labor, saves time and effort, ensures production quality, reduces production costs, and improves production efficiency.

[0060] Preferred, such as Figures 4 to 6As shown, to prevent the terminal 11 from shifting during the stamping process and causing incomplete stamping, a first sliding limit block is provided on each side of the first stamping baffle 24 facing the first stamping column 23. A first sliding limit groove is formed on the first sliding limit block for the connecting piece 111 to be inserted into the sliding limit. The first inclined stamping surface 231 and the second inclined stamping surface 241 are located at the upper end of the first sliding limit groove. The external conveying mechanism places the connecting piece 111 into the first sliding limit groove and pushes the connecting piece 111 to move the entire brush assembly 1 forward. The connecting piece 111 is limited in the first sliding limit groove. During this process, the connecting end 112 on the connecting piece 111 is inclined and stamped by the first inclined stamping surface 231 and the second inclined stamping surface 241, achieving the purpose of precise stamping, effectively improving the accuracy of this stamping and shaping device, and preventing the problem of incomplete stamping. By placing the first inclined stamping surface 231 and the second inclined stamping surface 241 at the upper end of the first sliding limiting groove, the connecting piece 111 is protected and limited in the first sliding limiting groove when the first inclined stamping surface 231 and the second inclined stamping surface 241 are stamped, and will not be deformed by the first inclined stamping surface 231 and the second inclined stamping surface 241, which is beneficial for subsequent transmission and processing.

[0061] For other structural configurations of this first stamping and forming device 2, such as Figures 4 to 6 As shown, the first stamping and shaping device 2 further includes a first stamping and shaping first limiting plate 25 disposed on the output shaft of the first stamping and shaping drive motor 22, at least one first stamping and shaping telescopic column 26 disposed at one end on the side of the first stamping and shaping first limiting plate 25, a first stamping and shaping spring 27 sleeved on the first stamping and shaping telescopic column 26, and a first stamping and shaping second limiting plate 28 disposed at the other end of the first stamping and shaping telescopic column 26; one end of the first stamping column 23 away from the first inclined stamping surface 231 is disposed on the first stamping and shaping first limiting plate 25, and the other end passes through the first stamping and shaping second limiting plate 28 to stamp and deform the connecting end 112.

[0062] The first stamping and shaping drive motor 22 starts, driving the first stamping and shaping first limiting plate 25, which is set on its output shaft, to move forward. The first stamping and shaping telescopic column 26, which is set on the first stamping and shaping first limiting plate 25, drives the first stamping and shaping second limiting plate 28 to move forward simultaneously, so that the first stamping and shaping second limiting plate 28 presses against the connecting piece 111, fixing and limiting the connecting piece 111. The first stamping and shaping drive motor 22 continues to move forward. At this time, the first stamping and shaping telescopic column 26 retracts, the first stamping and shaping spring 27 is compressed for buffering, and the first stamping and shaping first limiting plate 25 is driven to continue to move forward, so that the first stamping column 23 on the first stamping and shaping first limiting plate 25 passes through the first stamping and shaping second limiting plate 28 and stamps and deforms the connecting end 112. By setting a first stamping and shaping first limiting plate 25, a first stamping and shaping second limiting plate 28, a first stamping and shaping telescopic column 26, and a first stamping and shaping spring 27, the pressure of the first stamping and shaping drive motor 22 is buffered, thereby reducing the impact force on the connecting end 112 while stamping it, effectively preventing damage to the connecting end 112 caused by instantaneous stamping. By setting the first stamping column 23 to pass through the first stamping and shaping second limiting plate 28, the first stamping and shaping second limiting plate 28 limits the first stamping column 23, improving the stamping accuracy of the first stamping column 23, and thus effectively ensuring the stamping efficiency of this stamping and shaping device.

[0063] Preferred, such as Figures 4 to 6 As shown, there are two sets of the first stamping and shaping telescopic columns 26, which are respectively set on both sides of the first stamping and shaping first limiting plate 25. There are also two sets of the first stamping and shaping springs 27, which are respectively sleeved on the two sets of the first stamping and shaping telescopic columns 26, so that the buffering force on both sides of the first stamping and shaping first limiting plate and the first stamping and shaping second limiting plate is uniform.

[0064] To better stamp terminal 11, such as Figures 4 to 6 As shown, the first stamping and forming second limiting plate 28 is provided with at least one first stamping and forming through post that can pass through the through hole 1111. When the first stamping and forming second limiting plate 28 is driven by the first stamping and forming drive motor 22, the speed of the connecting piece 111 being pushed forward by the external conveying mechanism is coordinated, so that the first stamping and forming through post on the first stamping and forming second limiting plate 28 passes through the through hole 1111 while being pushed forward, thereby positioning the connecting piece 111. This facilitates the first stamping post 23 to stamp and bend the connecting end 112, improves the accuracy of this stamping and forming device, effectively ensures the yield rate, and improves production efficiency.

[0065] Regarding the specific structural configuration of the second stamping and shaping device 4, as follows: Figures 11 to 12 As shown, the second stamping and shaping device 4 includes a second stamping and shaping bracket 41 mounted on a platform, a second stamping and shaping drive motor 42 disposed on one end of the second stamping and shaping bracket, a second stamping column 43 disposed on the output shaft of the second stamping and shaping drive motor 42, and a second stamping baffle 44 disposed on the other end of the second stamping and shaping bracket 41. The second stamping and shaping drive motor 42 drives the second stamping column 43 to press against the second stamping baffle 44 and press it against the connecting end 112, thus stamping the connecting end 112 to an angle parallel to the second stamping baffle 44. The brush assembly 1, with the adhesive particles already applied, is conveyed to the second stamping baffle 44 by an external conveying mechanism. The second stamping and shaping drive motor 42 is started, driving the second stamping column 43, which is set on its output shaft, to press towards the connecting end 112, stamping the connecting end 112 to an angle parallel to the second stamping baffle 44, thereby restoring the connecting end 112 to its initial position, which is beneficial for subsequent processing and assembly.

[0066] Preferred, such as Figures 11 to 12 As shown, in order to prevent the terminal 11 from shifting during the stamping process and causing incomplete stamping, a second sliding limit block is provided on each side of the second stamping baffle 44 facing the second stamping column 43. A second sliding limit groove is formed on the second sliding limit block for the connecting piece 111 to be inserted into the sliding limit. The external conveying mechanism inserts the connecting piece 111 into the second sliding limit groove and pushes the connecting piece 111 to move the entire brush assembly 1 forward. The connecting piece 111 is limited in the second sliding limit groove, and during this process, the connecting end 112 on the connecting piece 111 is stamped by the second stamping column 43, which achieves the purpose of precise stamping, effectively improves the accuracy of this stamping and shaping device, and prevents the problem of incomplete stamping.

[0067] For other structural configurations of the second stamping and forming device 4, such as Figures 11 to 12 As shown, the second stamping and shaping device 4 further includes a second stamping and shaping first limiting plate 45 disposed on the output shaft of the second stamping and shaping drive motor 42, at least one second stamping and shaping telescopic column 46 disposed at one end on the side of the second stamping and shaping first limiting plate 45, a second stamping and shaping spring 47 sleeved on the second stamping and shaping telescopic column 46, and a second stamping and shaping second limiting plate 48 disposed at the other end of the second stamping and shaping telescopic column 46; one end of the second stamping column 43 is disposed on the second stamping and shaping first limiting plate 45, and the other end passes through the second stamping and shaping second limiting plate 48 to stamp and reset the connecting end 112.

[0068] The second stamping and shaping drive motor 42 starts, driving the second stamping and shaping second limiting plate 48, which is mounted on its output shaft, to move forward. The second stamping and shaping telescopic column 46, which is mounted on the second stamping and shaping second limiting plate 48, drives the second stamping and shaping second limiting plate 48 to move forward synchronously, so that the second stamping and shaping second limiting plate 48 presses against the connecting piece 111, fixing and limiting the connecting piece 111. The second stamping and shaping drive motor 42 continues to move forward. At this time, the second stamping and shaping telescopic column 46 retracts, and the second stamping and shaping spring 47 is compressed for buffering. The second stamping and shaping second limiting plate 48 is driven to continue to move forward, so that the second stamping column 43 on the second stamping and shaping second limiting plate 48 passes through the second stamping and shaping second limiting plate 48 and stamps and deforms the connecting end 112 to an angle parallel to the second stamping baffle 44. By configuring a second stamping and forming second limiting plate 48, a second stamping and forming telescopic column 46, and a second stamping and forming spring 47, the pressure of the second stamping and forming drive motor 42 is buffered, thereby reducing the impact force on the connecting end 112 while stamping it, effectively preventing damage to the connecting end 112 caused by instantaneous stamping. By configuring the second stamping column 43 to pass through the second stamping and forming second limiting plate 48, the second stamping and forming second limiting plate 48 limits the second stamping column 43, improving the stamping accuracy of the second stamping column 43, and thus effectively ensuring the stamping efficiency of this stamping and forming device.

[0069] Preferred, such as Figures 11 to 12 As shown, there are two sets of the second stamping and shaping telescopic columns 46, which are respectively set on both sides of the second stamping and shaping second limiting plate 48. There are also two sets of the second stamping and shaping springs 47, which are respectively sleeved on the two sets of second stamping and shaping telescopic columns 46, so that the buffering force on the second stamping and shaping second limiting plate 48 and the two sides of the second stamping and shaping second limiting plate 48 is uniform.

[0070] To better stamp terminal 11, such as Figures 11 to 12 As shown, the second stamping and forming second limiting plate 48 is provided with at least one second stamping and forming through post that can pass through the through hole 1111. When the second stamping and forming second limiting plate 48 is driven by the second stamping and forming drive motor 42, the speed of the connecting piece 111 being pushed forward by the external conveying mechanism is coordinated, so that the second stamping and forming through post on the second stamping and forming second limiting plate 48 passes through the through hole 1111 while being pushed forward, thereby positioning the connecting piece 111. This facilitates the second stamping post 43 to stamp and bend the connecting end 112, improves the accuracy of this stamping and forming device, effectively ensures the yield rate, and improves production efficiency.

[0071] To further ensure the yield rate of this automatic adhesive granule applicator, such as Figures 13 to 15 As shown, this automatic adhesive granule applicator also includes a detection device 5 mounted on a platform. The detection device 5 includes a detection bracket 51 mounted on the platform, a detection baffle 52 mounted on the detection bracket 51 and used for sliding and limiting the brush assembly 1, a detection camera 53 mounted on the detection bracket 51 and aligned with the brush assembly 1 on the detection baffle 52, a defective product ejection structure 54 mounted on the detection bracket 51 and capable of passing through the detection baffle 52 to cut the connecting piece 111 in the brush assembly 1, and a detection fixing structure 55 mounted on the detection bracket 51. After being stamped and reset by the second stamping and shaping device 4, the brush assembly 1 is conveyed to the detection baffle 52 by the external conveying mechanism. The detection camera 53 takes a picture, and the picture is sent to the external control mechanism for comparison and judgment. If it is determined that the brush assembly 1 has problems such as misaligned glue particles, no glue particles, or damaged connecting end 112, the defective product ejection structure 54 is controlled to cut off the connecting end 112 with the problem part, and then the entire problematic part is ejected for recycling. During this process, the detection fixing structure 55 passes through the through hole 1111 to fix the brush assembly 1, preventing the brush assembly 1 from shifting during the operation of the detection camera 53 and the defective product ejection structure 54, which would lead to inaccurate detection and ejection.

[0072] For the detection camera 53, as Figure 13 As shown, it can be a CCD camera, etc., and the choice can be made according to the actual situation. Therefore, no specific restrictions are made in this embodiment.

[0073] The specific structural configuration of the defective product ejection structure 54 is as follows: Figures 13 to 14 As shown, the defective product ejection structure 54 includes an ejection motor 541 mounted on the detection bracket 51 and facing the detection baffle 52, an ejection column 542 disposed on the output shaft of the ejection motor 541, a receiving channel component 543 disposed at the end of the detection baffle 52 away from the ejection motor 541, and a receiving box 544 disposed at the tail end of the receiving channel component 543. A channel is formed inside the receiving channel component 543. An external control mechanism controls the ejection motor 541 to start, driving the ejection column 542 disposed thereon to press into the receiving channel component 543. The ejection column 542 presses against the defective part, breaking off the defective part, and continues to push the defective part into the channel of the receiving channel component 543. The defective part enters the receiving box 544 through the channel of the receiving channel component 543 and is collected for subsequent rectification, effectively ensuring the yield rate of this automatic adhesive granule applicator.

[0074] Preferred, such as Figures 13 to 14 As shown, in order to better push out the problematic part, the outermost part of the push-out post 542 is formed with a push-out guide surface that extends obliquely from the lower outside to the upper inside. By setting the push-out guide surface to contact the connecting end 112 before pushing out, force is applied to the lower part of the connecting end 112 to break the connecting end 112, thereby improving the pushing efficiency of the push-out post 542.

[0075] Regarding the specific structural configuration of the detection fixing structure 55, as follows: Figure 13 and Figure 15 As shown, the detection fixing structure 55 includes a fixing motor 551 mounted on the detection bracket 51 and a fixing turntable 552 mounted on the fixing motor 551. The turntable has several fixing blocks 5521 that can pass through the through hole 1111. The fixing motor 551 drives the fixing turntable 552 to rotate, thereby causing the fixing blocks 5521 on the fixed turntable 552 to pass through the through hole 1111, thus fixing the brush assembly 1 and facilitating the operation of the detection camera 53 and the defective product ejection structure 54.

[0076] It should be noted that the automatic adhesive granulation device for brush plates disclosed in this utility model is an improvement on the specific structure, but the specific control method is not an innovation of this utility model. The motor, spring, telescopic column, and other components involved in this utility model can be general standard parts or components known to those skilled in the art.
