Technical Field

[0001] The utility model relates to the technical field of glue supply equipment, in particular to an automatic glue supply device for UV glue. Background Art

[0002] Medical UV glue has the characteristics of light-proof and sealed storage.

[0003] In the prior art, for medical devices using UV glue, the UV glue in the original package is usually poured into a glue bucket for automatic glue supply. In the process of pouring glue, a large amount of air will inevitably be mixed in, resulting in bubbles in the glue liquid, which affects the performance of the UV glue; and combined with the light-shielding characteristics of UV glue, the glue pouring operation is also very inconvenient. Utility Model Content

[0004] In order to solve the above problems, the present application provides a UV glue automatic glue supply device with a reasonable structure, thereby eliminating the glue pouring operation, avoiding the formation of bubbles due to mixing of air during the glue pouring process, and effectively ensuring the performance of the UV glue.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An automatic glue supply device for UV glue comprises a barrel body with an opening facing upwards, a barrel cover is sealed at the open end of the barrel body, a positioning seat is installed on the inner bottom surface of the barrel body, a glue barrel is placed on the positioning seat, and the top opening of the glue barrel is open and connected with the inner space of the barrel body; an air inlet joint is installed on the barrel cover, and the air inlet joint is connected with an external air source; and also comprises a glue outlet pipe, one end of the glue outlet pipe extends into the inner bottom surface of the glue barrel, and the other end of the glue outlet pipe extends outward through the glue outlet joint on the barrel cover.

[0007] As a further improvement of the above technical solution:

[0008] A limit pin is installed through the barrel body from outside to inside, and the end of the limit pin extends into the limit hole on the wall surface of the positioning seat.

[0009] The positioning seat is embedded with a liquid level sensor, and the cable of the liquid level sensor passes through the barrel body through the outlet pair plug-in.

[0010] The structure of the positioning seat is as follows: it includes an annular main body assembled with the inner bottom surface of the barrel body, the inner wall surface of the annular main body is relatively concave to form an accommodating space for installing the liquid level sensor; the outer circumferential surface of the annular main body is concave to form an arc space communicating with the accommodating space.

[0011] The upper portion of the inner wall surface of the annular body is chamfered along the circumferential direction.

[0012] A pressure reducing valve is installed in series between the air inlet connector and the external air source.

[0013] The interior of the barrel body and the rubber barrel together form a relatively closed pressure space.

[0014] The upper part of the inner wall of the barrel is in the form of an outwardly flared conical surface.

[0015] The barrel cover is fitted on the barrel body from top to bottom, and the circumferential edge is locked and fixed via locking components arranged at intervals.

[0016] The top of the barrel body extends outward in the circumferential direction to form a flange structure, and the circumferential edge of the flange structure extends outward at intervals to form multiple U-shaped seats. A locking block is clamped in the U-shaped seat, and the locking block is installed by a pin shaft passing through the two arms of the U-shaped seat. The locking assembly passes through the barrel cover from top to bottom and is locked into the locking block.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

When in use, it is only necessary to place the purchased UV glue barrel on the positioning seat in the barrel body, open the opening of the glue barrel, cover the barrel cover, extend the glue outlet pipe into the inside of the glue barrel, and the high-pressure gas enters the barrel body through the air inlet joint. The pressure in the barrel body increases, and the glue liquid in the glue barrel is pressed out through the glue outlet pipe due to the pressure difference, so as to realize the automatic glue supply of UV glue and be used for daily use such as glue dispensing and glue discharge, thereby eliminating the glue pouring operation, avoiding the formation of bubbles due to mixing of air during the glue pouring process, and effectively ensuring the performance of UV glue.

[0019] The utility model also has the following advantages:

[0030] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, an automatic glue supply device for UV glue of this embodiment includes a barrel body 1 with an opening facing upward, a barrel cover 2 is sealed at the open end of the barrel body 1, a positioning seat 8 is installed on the inner bottom surface of the barrel body 1, a glue barrel 10 is placed on the positioning seat 8, and the top opening of the glue barrel 10 is open and connected with the internal space of the barrel body 1; an air inlet joint 22 is installed on the barrel cover 2, and the air inlet joint 22 is connected with an external air source; and also includes a glue outlet pipe 4, one end of the glue outlet pipe 4 extends into the inner bottom surface of the glue barrel 10, and the other end of the glue outlet pipe 4 extends outward through the glue outlet joint 21 on the barrel cover 2.

[0032] When in use, high-pressure gas enters the barrel body 1 through the air inlet joint 22, the pressure in the barrel body 1 increases, and the glue liquid in the glue barrel 10 is pressed out through the glue outlet pipe 4 due to the pressure difference, realizing automatic glue supply of UV glue, which is used for daily use such as glue dispensing and glue removal.

[0033] A limit pin 7 is installed through the barrel body 1 from outside to inside, and the end of the limit pin 7 extends into a limit hole 81 on the wall surface of the positioning seat 8 to achieve circumferential positioning of the positioning seat 8 in the barrel body 1.

[0034] A liquid level sensor 9 is embedded in the positioning seat 8 , and a cable of the liquid level sensor 9 passes through the barrel body 1 through the outlet pair plug-in 6 .

[0035] By setting the liquid level sensor 9, a reminder can be issued when the liquid level in the glue barrel 10 drops to a preset position, thereby realizing liquid level monitoring, so as to facilitate timely replacement of the glue barrel 10.

[0036] In this embodiment, two groups of liquid level sensors 9 with different liquid level heights can be arranged in the positioning seat 8, one group is used for reminding when the liquid level is low, and the other group is used for signal output when the glue is used up.

[0037] Of course, according to actual needs, a through-beam sensor can be arranged in the positioning seat 8 along the diameter direction for liquid level detection.

[0038] like Figure 4As shown, the structure of the positioning seat 8 is: it includes an annular main body 80 assembled with the inner bottom surface of the barrel body 1, and the inner wall surface of the annular main body 80 is relatively concave to form an accommodating space 83 for installing the liquid level sensor 9; the outer circumferential surface of the annular main body 80 is concave to form an arc space 85 connected with the accommodating space 83.

[0039] In this embodiment, the liquid level sensor 9 can be locked and fixed in the accommodating space 83 via fasteners such as screws to ensure reliable and stable installation relative to the positioning seat 8 and ensure effective monitoring of the liquid level in the glue barrel 10 on the positioning seat 8.

[0040] The cable of the liquid level sensor 9 can be routed through the accommodating space 83 to the communicating arc space 85, and then led out from the arc space 85 through the outlet line pair plug-in 6 on the barrel body 1, thereby achieving the routing while effectively ensuring the relative sealing of the internal space of the barrel body 1.

[0041] In this embodiment, a through hole 84 can be opened on the wall surface of the positioning seat 8 at the arc space 85 according to needs, so as to facilitate wiring and other usage needs.

[0042] A chamfer 82 is formed on the upper portion of the inner wall of the annular body 80 along the circumferential direction to facilitate the smooth placement and assembly of the rubber barrel 10 .

[0043] In this embodiment, the annular body 80 is adapted to the size and shape of the glue barrel 10 to effectively restrict the placement of the glue barrel 10 .

[0044] A pressure reducing valve 5 is installed in series between the air inlet connector 22 and the external air source to help ensure the stability of the air pressure entering the barrel body 1 and ensure continuous and stable glue discharge.

[0045] The interior of the barrel body 1 and the glue barrel 10 together form a relatively closed pressure space to form a pressure difference to achieve and ensure glue discharge, and the glue discharge is stable and smooth.

[0046] The upper portion of the inner wall of the barrel body 1 is in the form of an outwardly flared conical surface 11 .

[0047] The barrel cover 2 is fitted on the barrel body 1 from top to bottom, and the peripheral edge is locked and fixed by locking components 3 arranged at intervals.

[0048] In this embodiment, a fully open cover structure is adopted between the barrel cover 2 and the barrel body 1, so as to facilitate taking and placing the rubber barrel 10 after opening the cover.

[0049] In actual use, the barrel cover 2 and the barrel body 1 can also be set as a flip cover structure, so that the cover can be opened to take and put the plastic barrel 10.

[0050] The top of the barrel body 1 extends outwardly in the circumferential direction to form a flange structure 13, and the circumferential edge of the flange structure 13 extends outward at intervals to form multiple U-shaped seats 12. A locking block 31 is clamped in the U-shaped seat 12, and the locking block 31 is installed by a pin shaft passing through the two arms of the U-shaped seat 12. The locking assembly 3 passes through the barrel cover 2 from top to bottom and is locked into the locking block 31.

[0051] After the barrel cover 2 is placed on the barrel body 1 , the locking assembly 3 is sequentially locked into the locking block 31 of the barrel body 1 from top to bottom to achieve locking of the barrel cover 2 relative to the barrel body 1 .

[0052] In order to ensure the installation tightness between the barrel cover 2 and the barrel body 1, sealing members can be installed on the connecting surfaces thereof according to actual needs.

[0053] The usage of the utility model is:

[0054] When in use, just place the purchased UV glue barrel 10 on the positioning seat 8 in the barrel body 1, open the opening of the glue barrel 10, cover the barrel cover 2, and extend the glue outlet pipe 4 into the glue barrel 10. The high-pressure gas enters the barrel body 1 through the air inlet joint 22. The pressure in the barrel body 1 increases, and the glue liquid in the glue barrel 10 is pressed out through the glue outlet pipe 4 due to the pressure difference, thereby realizing automatic glue supply of UV glue, which is used for daily use such as dispensing and discharging.

[0055] According to actual use requirements, a three-way valve can be installed at the outlet end of the glue outlet pipe 4 to control the flow direction of the liquid and divide the pipeline into two routes, one for daily dispensing and the other as a glue discharge system before the start of a shift.

[0056] The utility model is simple to operate and easy to use, and not only realizes the automatic glue supply of UV glue, but also saves the glue pouring operation, avoids the formation of bubbles due to mixing of air during the glue pouring process, and effectively ensures the performance of the UV glue.
