Description

Technical Field

[0001] The utility model relates to the field of automotive gluing, in particular to a micro gluing nozzle for automotive body-in-white. Background Technique

[0002] The gluing process is a very important part in the manufacturing process of automotive body-in-white. Body gluing can not only improve the overall vehicle sealing and waterproof performance, achieve vibration and noise reduction, but also the main glues used in the welding workshop include hemming glue, expanding glue, spot welding sealant, vibration isolation film and structural glue, etc. The robot is used to smear the glue on different positions of the body-in-white respectively. When gluing some relatively narrow positions, it is necessary to replace the nozzle of the glue gun with a micro nozzle to reduce the glue output.

[0003] However, since the aperture of the through-hole position of the micro gluing is relatively small, when the nozzle position does not discharge glue, the internal glue inside the through-hole is easy to dry and block, resulting in more difficult subsequent glue removal. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a micro gluing nozzle for automotive body-in-white, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a micro gluing nozzle for automotive body-in-white, including a gluing nozzle, a nozzle sleeve is installed at the upper end of the gluing nozzle, a limit sliding groove is opened on the outer side of the nozzle sleeve, a protection mechanism is arranged on the outer side of the gluing nozzle, and the protection mechanism includes: a retaining seat and a sliding connecting rod. The upper end of the sliding connecting rod is installed with a push rod inside the limit sliding groove, a baffle mounting groove is opened on the lower surface of the retaining seat, a baffle is arranged inside the baffle mounting groove, one end of the baffle is connected with the retaining seat by an elastic rotating shaft, and a nozzle through-hole corresponding to the outer side of the gluing nozzle is opened inside the retaining seat.

[0006] As a further scheme of the utility model: an inclined chamfer is opened on the outer side of the upper end of the nozzle through-hole, and a spring connecting seat is installed on the lower surface of the retaining seat.

[0007] As a further scheme of the utility model: a glue gun connecting seat is installed at the upper end of the nozzle sleeve.

[0008] As a further scheme of the utility model: the protection mechanism is slidably connected with the limit sliding groove through the sliding connecting rod, and the inner diameter dimension length of the nozzle through-hole is the same as the outer diameter dimension length of the gluing nozzle.

[0009] As a further scheme of the utility model: the baffle is rotatably connected with the retaining seat through the elastic rotating shaft.

[0010] As a further solution of the utility model: a clamping spring is installed inside the spring connection seat.

[0011] As a further solution of the utility model: the nozzle sleeve is connected to the glue application nozzle in a through manner.

[0012] As a further solution of the utility model: a hydraulic cylinder is installed inside the glue gun connection seat at the upper end of the push rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] When the incision position at the lower end of the glue application nozzle corresponds to the position of the chamfer obliquely opened on the nozzle through hole as a whole, the baffle will be reset under the action of the elastic rotating shaft and cover the inside of the baffle installation groove as a whole, preventing the glue inside the glue application nozzle from leaking under the action of gravity. At the same time, under the shielding action of the baffle, the contact between the internal glue and the external air can be reduced, preventing the glue from drying up and blocking.

[0015] By controlling the contraction of the push rod driven by the hydraulic cylinder inside the glue gun connection seat as a whole, after pulling the sliding connecting rod into the inside of the limit chute as a whole, the glue application nozzle will push the baffle arranged inside the baffle installation groove downward as a whole, and then the glue application nozzle will penetrate out of the nozzle through hole as a whole for glue application treatment.

Specific implementation mode

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, this embodiment provides a micro glue - applying nozzle for an automotive white body, including a glue - applying nozzle 1. A nozzle sleeve 2 is installed at the upper end of the glue - applying nozzle 1. The nozzle sleeve 2 is connected to the glue - applying nozzle 1 in a through - connection manner. A limiting sliding groove 5 is formed on the outer side of the nozzle sleeve 2. A protection mechanism 4 is arranged on the outer side of the glue - applying nozzle 1. The protection mechanism 4 includes: a retaining seat 401 and a sliding connecting rod 402. The protection mechanism 4 is slidably connected to the limiting sliding groove 5 through the sliding connecting rod 402. At the upper end of the sliding connecting rod 402 located inside the limiting sliding groove 5, a push rod 6 is installed. A baffle mounting groove 404 is formed on the lower surface of the retaining seat 401. A baffle 405 is arranged inside the baffle mounting groove 404. One end of the baffle 405 is connected to the retaining seat 401 by an elastic rotating shaft 406. The baffle 405 is rotatably connected to the retaining seat 401 through the elastic rotating shaft 406. A nozzle through - hole 407 corresponding to the outer side of the glue - applying nozzle 1 is formed inside the retaining seat 401. The inner diameter dimension length of the nozzle through - hole 407 is the same as the outer diameter dimension length of the glue - applying nozzle 1.

[0024] As Figures 2-5 shown, in this embodiment, an inclined chamfer 408 is formed on the outer side of the upper end of the nozzle through - hole 407. A spring connecting seat 403 is installed on the lower surface of the retaining seat 401. A clamping spring is installed inside the spring connecting seat 403. A glue gun connecting seat 3 is installed at the upper end of the nozzle sleeve 2. At the upper end of the push rod 6 located inside the glue gun connecting seat 3, a hydraulic cylinder is installed.

[0025] The working principle of the present utility model is as follows: When in use, the whole of the protection mechanism 4 is correspondingly placed at the lower end position of the glue application nozzle 1 to ensure that the center position of the glue application nozzle 1 coincides with the position of the nozzle through hole 407. After the push rod 6 and the sliding link 402 are integrally fixedly connected, by controlling the contraction of the push rod 6 driven by the hydraulic cylinder inside the glue gun connection seat 3, when the sliding link 402 is pulled upwards into the limit chute 5 as a whole, the whole of the glue application nozzle 1 will push the baffle 405 arranged inside the baffle mounting groove 404 downwards as a whole, and then the whole of the glue application nozzle 1 will penetrate out from the nozzle through hole 407. Then, the mechanical arm is used to drive the glue gun connection seat 3 to control the glue application nozzle 1 to apply glue to the corresponding position of the vehicle body. After the glue application is completed, the hydraulic cylinder is used to drive the push rod 6 to push the whole of the protection mechanism 4 towards the lower end of the glue application nozzle 1. When the notch position at the lower end of the glue application nozzle 1 corresponds to the position of the chamfer 408 opened on the nozzle through hole 407 as a whole, the baffle 405 will reset under the action of the elastic rotating shaft 406 and cover inside the baffle mounting groove 404, and then the baffle 405 will cover the lower end position of the glue application nozzle 1 as a whole, which can be used to block the lower end of the glue application nozzle 1 to prevent the internal glue from leaking under the action of gravity. At the same time, under the blocking action of the baffle 405, the contact between the internal glue and the external air can be reduced to prevent the glue from drying up and blocking.
