[0026] Since the rapid glue coating of the side of the needle cylinder narrow groove 01 is the core and difficulty, the groove width of the needle cylinder narrow groove 01 is 0.776mm, and it is difficult to achieve high-speed uniform coating of the side wall when the anaerobic glue is coated on the needle cylinder narrow groove 01. Referring to Figures 1 to 4 The technical scheme of the present application includes:

[0027] The technical scheme of the present application includes:

[0028] The technical scheme of the present application includes:

[0029] The glue coating machine box 2 is arranged on the frame 1, and the glue coating mechanism 201 and the mounting mechanism 202 for fixing the needle cylinder 0 are arranged in the glue coating machine box 2. The mounting mechanism 202 is externally connected with the power motor 3 at one end, and the opening 203 is arranged at the other end of the mounting mechanism 202.

[0030] The glue coating mechanism 201 comprises the anaerobic glue nozzle 4, the scraper 5 and the smearing transition wheel 6 arranged in the inner cavity of the glue coating machine box 2. The anaerobic glue nozzle 4 is a high-pressure air nozzle in the prior art, which blows away the anaerobic glue by spraying high-pressure air to spread the anaerobic glue. The anaerobic glue nozzle 4 and the smearing transition wheel 6 are sequentially arranged above and below the mounting mechanism 202, respectively. The glue coating machine box 2 is provided with the glue containing cavity 204 at the bottom, the smearing transition wheel 6 is immersed in the anaerobic glue in the glue containing cavity 204, the scraper 5 is arranged on the mounting mechanism 202 in an inclined manner. In operation, the smearing transition wheel 6 is arranged below the needle cylinder 0 to pre-coat the anaerobic glue, and the part not uniformly coated by the scraper 5 is sprayed on the needle cylinder 0 by the anaerobic glue nozzle 4, so that the anaerobic glue on the upper side of the groove is uniformly spread to the two side surfaces of the needle cylinder narrow groove 01, i.e. the side wall of the needle cylinder narrow groove 01, to realize rapid and uniform smearing of the side surface.

[0031] The scraper 5 comprises the forward scraper 5a and the reverse scraper 5b arranged in opposite inclined directions, and the glue coating machine box 2 is provided with the mounting rod 205 corresponding to the forward scraper 5a and the reverse scraper 5b. The forward scraper 5a and the reverse scraper 5b are both inserted into the mounting rod 205.

[0032] Further, the mounting end 501 is provided with the connecting opening 5011 which is inserted towards the mounting rod 205 to complete the connection and installation of the scraper 5 and the mounting rod 205. The outer diameter of the mounting rod 205 is smaller than the inner diameter of the mounting end 501, so that the shaft connection between the scraper 5 and the mounting rod 205 is realized, and the scraper 5 can rotate around the mounting rod 205. In the actual glue coating process, the needle cylinder 0 rotates with the mounting mechanism 202, and the rotation rubbing between the needle cylinder 0 and the scraper 5 occurs, so that the anaerobic glue on the needle cylinder 0 is scraped by the forward scraper 5a and the reverse scraper 5b in different directions, and the anaerobic glue smoothly enters the needle cylinder narrow groove 01.

[0033] The thickness of the coating brush is 0.1mm-0.2mm. The coating brush with the above-mentioned thickness can uniformly coat the side wall of the narrow groove 01 of the needle cylinder, and the coating brush is preferably wool in the present application. Since wool is soft and has a smooth and unique texture, it can be used in the present application to absorb an appropriate amount of anaerobic adhesive and smoothly transfer the anaerobic adhesive to the needle cylinder 0, and the uniform coating is achieved by the cooperation of the thickness specification. The uniform scraper 601 is arranged beside the coating transition wheel 6 and is in contact with the coating transition wheel 6. The uniform scraper 601 is used to uniformly scrape the anaerobic adhesive on the coating transition wheel 6 to better achieve high-speed uniform coating. At the same time, the scraping direction of the uniform scraper 601 is consistent with the rotation direction of the coating transition wheel 6.

[0034] The mounting mechanism 202 includes a sleeve 10 and a limiting ring 7 arranged on the inner wall of the rack 1. The axis of the limiting ring 7 coincides with the axis of the sleeve 10. The rack 1 is provided with a hole 206 at the axis of the limiting ring 7. The sleeve 10 is inserted into the hole 206. The end of the sleeve 10 extends out of the hole 206 and is connected with the power motor 3.

[0035] The power motor 3 is mounted on the motor mounting frame 301. The bottom of the motor mounting frame 301 is connected with the ball screw 801. The ball screw 801 is connected with the screw rod 802 of the linear motor 8. The movement of the ball screw 801 is controlled by the linear motor 8, so that the power motor 9 moves forward and backward relative to the hole 206. At the same time, the sleeve 10 connected with the power motor 9 moves forward and backward. The sleeve 10 and the needle cylinder 0 are inserted into each other. After the anaerobic adhesive coating of one needle cylinder 0 is completed, the sleeve 10 is controlled to move towards the opening 203 and extend out of the opening 203 by controlling the linear motor 8. In this way, the needle cylinder 0 after coating is conveniently taken out.

[0036] The limiting ring 7 is provided with an inlet 701. The inlet 701 is connected with an internal flow channel 702. The end of the internal flow channel 702 is connected with an outlet 703. The outlet 703 is arranged on the inner wall of the upper half ring of the limiting ring 7. Since the limiting ring 7 inserts a part of the needle cylinder 0, the anaerobic adhesive is dropped into the part of the needle cylinder 0 through the outlet 703, so that the entire needle cylinder 0 can be coated. After the preliminary coating is completed, the sleeve 10 is controlled to move forward to further uniformly scrape the part coated by the outlet 701. The length of the scraper 5 is greater than the length of the needle cylinder 0. The length of the coating transition wheel 6 is greater than the sum of the length of the needle cylinder 0 and the height of the limiting ring 7.

[0037] The above disclosure is only a preferred embodiment of the present application, and of course cannot limit the scope of the patent rights of the present application. Any equivalent structure or equivalent process conversion using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
