[0034] Therefore, the embodiment can realize batch glue filling operation by arranging a plurality of glue heads 41, and greatly improves the production efficiency; and the precise glue filling machine device 1 further comprises the glue head detection device 70, the height and horizontal position of each glue head 41 can be automatically and quickly detected by the height detection sensor 71 and the centering detection assembly 72, then manual fine adjustment is performed by manual intervention, eccentricity is corrected in time, so that the positions of the glue heads 41 are not deviated, product lamp tube glue can be avoided, product yield can be improved, and product quality can be ensured.

[0035] As shown in Figure 2 In the embodiment, the glue head detection device 70 comprises a plurality of centering detection assemblies 72 arranged side by side, and the number and mutual spacing of the centering detection assemblies 72 are consistent with the glue heads 41 of the multi-head glue outlet mechanism 40. Therefore, a plurality of centering detection assemblies 72 are arranged, and the horizontal position of all the glue heads 41 can be detected at one time.

If the height of the needle tube 411 of the dispensing head 41 is inconsistent and / or the horizontal position of the needle tube 411 is deviated, manual intervention is performed to abnormally correct and adjust the dispensing head 41.

[0038] Specifically, the dispensing head detection and correction can include the following specific steps:

[0039] S1, detection and correction starts;

[0040] S2, height detection of the needle tube of the dispensing head is performed; the three-axis driving mechanism 50 drives one of the dispensing heads 41 of the multi-head glue discharging mechanism 40 to move above the height sensor 71; then the dispensing head 41 is lowered by a predetermined height, and the detection end 711 of the height sensor 71 is contacted during the lowering process to obtain the height of the needle tube 411 of the current dispensing head 41.

[0042] S4, horizontal position detection of the needle tube of the dispensing head is performed;

[0043] S41, left-right position detection of the needle tube of the dispensing head is performed; the three-axis driving mechanism 50 drives the dispensing head 41 of the multi-head glue discharging mechanism 40 to move and extend into the detection area of the left-right position sensor 722 in the detection window 721 of the centering detection assembly 72 to obtain the left-right deviation B of the dispensing head. In the embodiment, the dispensing head is moved forward and backward within the detection window 721 to pass through the detection range of the left-right position sensor 722. The left-right deviation B of the dispensing head is the horizontal left-right distance between the dispensing head and the left-right position sensor during detection. If the left-right deviation B of the dispensing head is not within the left-right setting range, the needle tube 411 of the dispensing head 41 is adjusted to be within the left-right setting range through manual fine adjustment, otherwise, the needle tube 411 of the dispensing head 41 is not corrected;

[0044] S42, detection of the front and back positions of the dispensing head needle tube; the three-axis driving mechanism 50 drives the dispensing head 41 of the multi-head dispensing mechanism 40 to move and extend into the detection area of the front and back position sensor 723 in the detection window 721 of the centering detection assembly 72, so as to obtain the current front and back offset A of the dispensing head, in the embodiment, the dispensing head can be moved left and right in the detection window 721, so that the dispensing head passes through the detection range of the left and right position sensor 722, the front and back offset A of the dispensing head is the horizontal front and back distance between the dispensing head and the front and back position sensor during detection, if the front and back offset A of the dispensing head is not within the front and back set range, the dispensing head 41 needle tube 411 is adjusted to be within the front and back set range by manual fine adjustment, otherwise, the front and back of the dispensing head 41 needle tube 411 is not corrected;

[0045] The execution sequence of the above steps S41 and S42 is not limited;

[0046] S5, detection correction ends.

[0047] Part of the process steps of the above process can be set as a corresponding running program, and then executed through a control module, of course, the specific process execution mode is not limited thereto.
