Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying equipment maintenance, in particular to an automatic cleaning device for a glue spraying machine. Background Art

[0002] After each glue spraying operation, glue will remain on the glue spray head of the glue spray machine. After a period of time, the glue will solidify on the glue spray head. If the glue spray head is not cleaned, it is easy to cause uneven glue spraying of the product, affecting the production quality of the product, and often requires rework. Therefore, the glue spray head must be cleaned before each glue spraying operation. At present, the glue spray head is generally cleaned manually, that is, the colloid solidified on the glue spray head is peeled off manually. This operation method is highly dependent on manual labor and has low cleaning efficiency. It is easy to forget to clean the glue spray head before each glue spraying, which affects product quality. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an automatic cleaning device for a glue spraying machine, which improves the cleaning efficiency and ensures that the glue spraying head is in a smooth state before each operation.

[0006] The working platform is provided with a plurality of through holes, and the fixing assembly is connected to one of the through holes;

[0007] The cleaning member is detachably connected to the fixing assembly, and at least a portion of the cleaning member is located on a side of the fixing assembly away from the working platform, so that the glue spraying head can contact the cleaning member.

[0008] Further, the fixing assembly includes a fixing member and a collar;

[0009] The fixing member is detachably connected to the through hole, the cleaning member is covered on the outside of one end of the fixing member away from the working platform, and the sleeve is sleeved on the outside of the cleaning member so that part of the cleaning member is clamped between the sleeve and the fixing member.

[0010] Furthermore, the fixing piece is threadedly connected to the through hole.

[0011] Furthermore, the fixing piece is interference fit with the through hole.

[0012] Furthermore, the outer diameter of the fixing member gradually increases in a direction approaching the working platform.

[0013] Furthermore, the inner diameter of the collar gradually increases in a direction approaching the working platform, and the maximum inner diameter of the collar is larger than the minimum outer diameter of the fixing member and smaller than the maximum outer diameter of the fixing member.

[0014] Furthermore, an end surface of one side of the fixing member away from the working platform is hollowed out.

[0015] Furthermore, the fixing assembly is connected to a through hole located at an edge of the working platform.

[0016] The beneficial effect of the utility model is that a fixing component is arranged on the working platform to fix the cleaning part, so that after the glue spraying head finishes spraying each time, it can be moved to the area where the cleaning part is located under the drive of the three-axis moving mechanism, contact the cleaning part and move back and forth, thereby realizing automatic cleaning of the glue spraying head and improving the cleaning efficiency of the glue spraying head.

[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0024] Please refer to Figure 1-Figure 3, the automatic cleaning device of the glue spraying machine, the glue spraying machine includes a three-axis moving mechanism, a glue spraying head and a working platform 1, the glue spraying head is connected to the three-axis moving mechanism by transmission, the glue spraying head is arranged relative to the working platform 1 and can move in the area where the working platform 1 is located, and the automatic cleaning device 2 includes a cleaning member 21 and a fixing component 22; a plurality of through holes 11 are opened on the working platform 1, and the fixing component 22 is connected to one of the through holes 11; the cleaning member 21 is detachably connected to the fixing component 22, and the cleaning member 21 is at least partially located on the side of the fixing component 22 away from the working platform 1, so that the glue spraying head can contact the cleaning member 21. Among them, different bases can be assembled on the working platform 1, so that different products can be placed in matching bases for glue spraying; each base is connected to the corresponding through hole 11. Optionally, the cleaning member 21 uses a cleaning cloth with a thickness of 0.5 to 2 mm, and preferably, the thickness of the cleaning member 21 is 1 mm.

[0025] It can be understood that by arranging a fixing component 22 on the working platform 1 to fix the cleaning member 21, after the glue spraying head finishes each time, it can be moved to the area where the cleaning member 21 is located under the drive of the three-axis moving mechanism, contact the cleaning member 21 and move back and forth, thereby realizing automatic cleaning of the glue spray head and improving the cleaning efficiency of the glue spray head. At the same time, it avoids the colloid solidifying on the glue spray head and causing the glue spray head to be blocked, ensuring that the glue spray head is in a smooth state before each operation.

[0026] In some embodiments, the fixing assembly 22 includes a fixing member 221 and a collar 222; the fixing member 221 is detachably connected to the through hole 11, the cleaning member 21 is covered on the end of the fixing member 221 away from the working platform 1, and the collar 222 is sleeved on the cleaning member 21, so that part of the cleaning member 21 is sandwiched between the collar 222 and the fixing member 221. The cooperation between the collar 222 and the fixing member 221 limits the cleaning member 21, making it easy to replace the cleaning member 21.

[0027] In some embodiments, the fixing member 221 is threadedly connected to the through hole 11, or the fixing member 221 is interference fit with the through hole 11. Through these two connection methods, it is easy to disconnect the fixing member 221 from the working platform 1, and then it is easy to move the fixing member 221 to make way for different bases.

[0028] In some embodiments, the outer diameter of the fixing member 221 gradually increases in the direction approaching the working platform 1, and the maximum inner diameter of the collar 222 is greater than the minimum outer diameter of the fixing member 221 and smaller than the maximum outer diameter of the fixing member 221, or, the inner diameter of the collar 222 gradually increases in the direction approaching the working platform 1, and the maximum inner diameter of the collar 222 is greater than the minimum outer diameter of the fixing member 221 and smaller than the maximum outer diameter of the fixing member 221. Through the above two embodiments, the collar 222 and the fixing member 221 can be tightly matched, and because the cleaning member 21 is clamped between the circumferential inner wall of the collar 222 and the circumferential outer wall of the fixing member 221, the three are interference fit to achieve a tight connection.

[0029] In some embodiments, the end surface of one side of the fixing member 221 away from the working platform 1 is hollowed out so that the cleaning member 21 has deformation space in the area, achieving flexible contact between the glue spraying head and the cleaning member 21, and protecting the glue spraying head.

[0030] In some embodiments, the fixing component 22 is connected to the through hole 11 located at the edge of the working platform 1. Since the base is usually arranged in the middle of the working platform 1, the fixing component 22 is arranged at the edge of the working platform 1, which can avoid the fixing component 22 interfering with the normal operation of the glue spray head.

[0031] Please refer to Figure 1-Figure 3 , Embodiment 1 of the present utility model is:

[0032] The automatic cleaning device 2 of the glue spraying machine includes a three-axis moving mechanism, a glue spraying head and a working platform 1.

The automatic cleaning device 2 includes a cleaning member 21 and a fixing component 22. A plurality of through holes 11 are provided on the working platform 1. The fixing component 22 is connected to one of the through holes 11 located on the edge of the working platform 1. The cleaning member 21 is detachably connected to the fixing component 22, and the cleaning member 21 is at least partially located on the side of the fixing component 22 away from the working platform 1, so that the glue spraying head can contact the cleaning member 21. Among them, different bases can be assembled on the working platform 1, so that different products can be placed in matching bases for glue spraying; each base is connected to the corresponding through hole 11. Preferably, the cleaning member 21 is a cleaning cloth with a thickness of 1 mm.

[0033] In this embodiment, the fixing assembly 22 includes a fixing member 221 and a ring 222; the fixing member 221 is detachably connected to the through hole 11, the cleaning member 21 is covered on the outside of the end of the fixing member 221 away from the working platform 1, and the ring 222 is sleeved on the outside of the cleaning member 21 so that part of the cleaning member 21 is clamped between the ring 222 and the fixing member 221; the fixing member 221 is threadedly connected to the through hole 11.

[0034] In this embodiment, the outer diameter of the fixing member 221 gradually increases in the direction approaching the working platform 1, and the inner diameter of the ring 222 gradually increases in the direction approaching the working platform 1, and the maximum inner diameter of the ring 222 is greater than the minimum outer diameter of the fixing member 221 and smaller than the maximum outer diameter of the fixing member 221.

[0035] In this embodiment, the end surface of one side of the fixing member 221 away from the working platform 1 is hollowed out.
