[0047] The invention provides a glue dispensing device.

[0048] In the embodiment of the present invention, Figure 2 and Figure 3 As shown, the glue dispensing device includes a bracket 31, a glue barrel 32, a driving mechanism 33 and an extruding member 34. The glue barrel 32 is arranged on the bracket 31 for storing glue liquid; the driving mechanism 33 is arranged on the bracket 31, and the extruding member 34 is connected to the output shaft of the driving mechanism 33. The driving mechanism 33 is used to drive the extruding member 34 to move along the axial direction of the glue barrel 32 to squeeze the glue liquid in the glue barrel 32.

[0049] The glue barrel 32 of the technical solution of the present invention is arranged on the bracket 31, and is used to store glue liquid, so that the glue liquid in the glue barrel 32 can be continuously dispensed onto the product, avoiding the user from frequently supplying glue and reducing manual operation; the driving mechanism 33 is arranged on the bracket 31, and the extruding member 34 is connected to the output shaft of the driving mechanism 33. The driving mechanism 33 is used to drive the extruding member 34 to move along the axial direction of the glue barrel 32 to squeeze the glue liquid in the glue barrel 32, thereby squeezing the glue liquid in the glue barrel 32 out of the liquid outlet of the glue barrel 32. In the process of the glue liquid being squeezed out of the glue barrel 32, no manual participation is required, which improves the degree of automation of the glue dispensing device 3, and also improves the efficiency and accuracy of glue dispensing; by controlling the amount of movement of the extruding member 34 along the axial direction of the glue barrel 32 driven by the driving mechanism 33, the amount of glue liquid squeezed out of the glue barrel 32 can be more accurately controlled to improve the accuracy of glue dispensing, and its structure is also simpler.

[0050] In one embodiment, if Figure 2 and Figure 3 As shown, the driving mechanism 33 includes a servo motor 331 and a transmission mechanism 332. The servo motor 331 is arranged on the bracket 31, and the transmission mechanism 332 is arranged on the bracket 31 and is transmission-connected to the output shaft of the servo motor 331 and the extrusion member 34. The transmission mechanism 332 transmission-connects the output shaft of the servo motor 331 and the extrusion member 34, thereby improving the flexibility of the installation position of the servo motor 331 and the extrusion member 34 and improving the structural expandability of the dispensing device 3.

[0051] Specifically, the servo motor 331 can detect the pressure of the extrusion member 34 on the glue liquid in the glue barrel 32, and then calculate the rotation speed of the servo motor 331. By controlling the rotation speed of the servo motor 331, the servo motor 331 can be driven to accurately control the axial displacement of the extrusion member 34 along the glue barrel 32, thereby improving the accuracy of the amount of glue squeezed out of the glue barrel 32.

[0052] In one embodiment, if Figure 3 and Figure 4 As shown, the bracket 31 includes a back plate 311, a mounting plate 312 and a support plate 313, the servo motor 331 is arranged on the back plate 311, the mounting plate 312 is fixed on the back plate 311, the transmission mechanism 332 is arranged on the mounting plate 312, the support plate 313 is fixed on one end of the back plate 311 away from the mounting plate 312, and the glue barrel 32 is arranged on the support plate 313, so that the installation positions of the back plate 311, the mounting plate 312 and the support plate 313 are more reasonable, the connection structure of the transmission mechanism 332 and the extrusion member 34 and the servo motor 331 is simplified, and the structure of the glue dispensing device 3 is more compact.

[0053] In one embodiment, if Figure 3As shown, the servo motor 331 and the glue barrel 32 are respectively arranged on both sides of the back plate 311 , so that the servo motor 331 and the glue barrel 32 can be more compactly installed on the bracket 31 , thereby reducing the installation volume of the glue dispensing device 3 .

[0054] In one embodiment, if Figure 3 As shown, the servo motor 331 and the glue barrel 32 are arranged on the same side of the mounting plate 312 to reduce the height accumulation of the servo motor 331 and the glue barrel 32 along the axial direction of the glue barrel 32 , thereby reducing the installation volume of the glue dispensing device 3 .

[0055] In one embodiment, if Figure 3 As shown, the transmission mechanism 332 includes a first synchronous wheel 3321 and a second synchronous wheel 3322. The first synchronous wheel 3321 is rotatably disposed on the mounting plate 312 and is fixedly connected to the output shaft of the servo motor 331; the second synchronous wheel 3322 is rotatably disposed on the mounting plate 312 and is synchronously rotatably connected with the first synchronous wheel 3321. The extrusion member 34 is transmission-connected to the second synchronous wheel 3322 so as to drive the extrusion member 34 to move axially along the glue barrel 32 through the second synchronous wheel 3322. Since the first synchronous wheel 3321 is fixedly connected to the output shaft of the servo motor 331, the servo motor 331 can drive the first synchronous wheel 3321 to rotate, and the first synchronous wheel 3321 then drives the second synchronous wheel 3322 connected to it for synchronous rotation to rotate, and then the second synchronous wheel 3322 drives the extrusion member 34 to move axially along the glue barrel 32, so that the installation position of the servo motor 331 is more flexible, so that the movement of the output shaft of the servo motor 331 is transmitted to the extrusion member 34 through the transmission mechanism 332 with higher accuracy, thereby reducing the accumulation of errors.

[0056] As an optional embodiment, the first synchronous wheel 3321 is meshed with the second synchronous wheel 3322 so that the first synchronous wheel 3321 and the second synchronous wheel 3322 are connected to rotate synchronously.

[0057] In one embodiment, if Figure 3 As shown, the transmission mechanism 332 also includes a synchronous belt 3323, and the synchronous belt 3323 is tensioned on the first synchronous wheel 3321 and the second synchronous wheel 3322 to synchronously rotate and connect the first synchronous wheel 3321 and the second synchronous wheel 3322, thereby improving the flexibility of the installation position of the servo motor 331 and avoiding the long distance between the first synchronous wheel 3321 and the second synchronous wheel 3322 so as to prevent the first synchronous wheel 3321 from being synchronously rotated and connected; the first synchronous wheel 3321 can also be synchronously rotated and connected with multiple second synchronous wheels 3322 to improve the flexibility of the structure of the dispensing device 3.

[0058] In one embodiment, if Figure 3As shown, the transmission mechanism 332 also includes a connecting member 3324 and a guide rod 3325. The extrusion member 34 is a screw rod, which passes through the second synchronous wheel 3322 and is threadedly connected to the second synchronous wheel 3322. One end of the screw rod away from the glue barrel 32 is fixed on the connecting member 3324. When the servo motor 331 drives the first synchronous wheel 3321 to rotate, the first synchronous wheel 3321 drives the second synchronous wheel 3322 to rotate, so that the screw rod is driven by the rotating second synchronous wheel 3322 to move along the axial direction of the glue barrel 32, that is, the rotational motion of the second synchronous wheel 3322 is converted into the linear motion of the screw rod, thereby improving the output accuracy of the driving mechanism 33, thereby improving the accuracy of glue dispensing, and at the same time simplifying the structure and reducing the cost;

[0059] The guide rod 3325 is passed through the mounting plate 312 and is fixedly connected to the connecting piece 3324. The guide rod 3325 can make the screw rod move along the axial direction of the glue barrel 32 to prevent the movement of the screw rod from deviating from the axial direction of the glue barrel 32 and affecting the dispensing accuracy. The screw rod and the guide rod 3325 are both fixedly connected to the connecting piece 3324, and the guide rod 3325 passes through the mounting plate 312, and the screw rod passes through the second synchronous wheel 3322 to limit the rotation of the screw rod and prevent the screw rod and the second synchronous wheel 3322 from rotating relative to each other and affecting the output accuracy of the screw rod.

[0060] Specifically, the screw rod is rotatably mounted on the mounting plate 312 via a bearing.

[0061] In one embodiment, if Figure 3 As shown, the glue barrel 32 includes a barrel body 321 and a sealing cover, and the barrel body 321 is used to store glue liquid so as to enable continuous dispensing;

[0062] The sealing cover is sealed at one end of the barrel body 321 close to the extrusion piece 34. A groove is provided on the sealing cover. An abutment block 35 corresponding to the groove is provided at one end of the extrusion piece 34 close to the sealing cover. The contour of the abutment block 35 gradually converges from the end away from the sealing cover to the end close to the sealing cover. The abutment block 35 extends into the groove to increase the contact area between the abutment block 35 and the sealing cover, improve the stability of the sealing cover driven by the extrusion piece 34 to avoid the sealing cover from shifting during the movement, resulting in a large error in the amount of glue squeezed out of the glue barrel 32 by the sealing cover, affecting the accuracy of glue dispensing; the sealing cover seals the glue barrel 32 to prevent the glue in the glue barrel 32 from leaking out.

[0063] As an optional solution, the abutment block 35 is fixed to an end of the lead screw close to the sealing cover.

[0064] As an alternative, Figure 3 As shown, the abutment block 35 is sealed against the inner wall of the glue barrel 32 , so that the glue barrel 32 is sealed by the abutment block 35 , and the glue liquid is directly squeezed by the abutment block 35 to squeeze the glue liquid out of the glue barrel 32 .

[0065] In one embodiment, if Figure 3 As shown, the glue barrel 32 further includes a protective cover 322 , and the barrel body 321 is disposed in the protective cover 322 to prevent external force from hitting the barrel body 321 and causing damage to the barrel body 321 .

[0066] In one embodiment, the protective cover 322 is a hard cover. Preferably, the protective cover 322 is a metal cover.

[0067] In one embodiment, if Figure 3 As shown, there are multiple glue barrels 32 and extrusion pieces 34, and the glue barrels 32 correspond to the extrusion pieces 34 one by one, so as to increase the storage capacity of the glue liquid, reduce the frequency of users replacing the glue barrels 32, and reduce manual participation.

[0068] Specifically, Figure 3 As shown, each extrusion member 34 passes through a corresponding second synchronous wheel 3322 , and all second synchronous wheels 3322 are connected to rotate synchronously with the first synchronous wheel 3321 through a synchronous belt 3323 , so that the servo motor 331 drives the extrusion member 34 to move.

[0069] Specifically, two glue barrels 32 are provided.

[0070] In one embodiment, if Figure 3 and Figure 5 As shown, the glue dispensing device 3 also includes a confluence piece 36, and a confluence channel 361 is provided in the confluence piece 36. The confluence channel 361 is connected to the inner cavities of multiple glue barrels 32 so that the glue in the glue barrels 32 can be collected in the confluence channel 361, thereby facilitating subsequent glue dispensing.

[0071] In one embodiment, if Figure 3 and Figure 5 As shown, the confluence channel 361 runs through the confluence piece 36, and plugs 37 are provided at both ends of the confluence piece 36 for sealing the confluence channel 361 so that the confluence channel 361 can be processed on the confluence piece 36, and the plugs 37 can block the port of the confluence channel 361 to prevent the glue from flowing out.

[0072] In one embodiment, if Figure 3 and 6 As shown, the glue dispensing device 3 also includes a limiter 38, which is arranged on the bracket 31. The limiter 38 abuts against the side of the glue barrel 32 to limit the radial movement of the glue barrel 32, thereby avoiding the movement of the glue barrel 32 relative to the bracket 31 and improving the accuracy of the amount of glue squeezed out of the glue barrel 32 by the extrusion member 34.

[0073] In one embodiment, if Figure 3 , Figure 4 and Figure 6As shown, the limiting member 38 is provided with a first arc groove 381 surrounding the side of the glue barrel 32, and the bracket 31 is provided with a second arc groove 3111 surrounding the side of the glue barrel 32. The glue barrel 32 is clamped between the first arc groove 381 and the second arc groove 3111 to improve the stability of the limiting member 38 in limiting the glue barrel 32. Preferably, the back plate 311 is provided with a second arc groove 3111.

[0074] The present invention also provides a dispensing device, such as Figure 1 and Figure 2 As shown, the glue dispensing equipment includes a box body 1, a needle nozzle 2 and a glue dispensing device 3 mentioned in any of the above embodiments.
