Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and more particularly to a device for fixing glue buckets and needles. Background Technology

[0002] The main functions of glue are bonding, sealing, masking, and vibration damping. It is widely used in industries such as LED, semiconductor manufacturing, and pharmaceuticals. As an important part of the dispensing system, the stability and accuracy of the dispensing needle and glue container directly affect the dispensing effect.

[0003] However, most existing glue canister fixing methods use an open circular plastic ring and a fastening screw, which is cumbersome and makes it difficult to fine-tune the position of the syringe. Currently, most glue canisters on the market are fixed using an open circular plastic ring and a fastening screw. This method is simple to manufacture and low in cost, but it has the following drawbacks: 1. Because the open circular plastic ring is subjected to localized force, the ring becomes an irregular ellipse after being stressed, which can cause the glue canister piston to jam; 2. The fastening screw is prone to loosening; 3. If the glue canister is not completely fixed, there is a risk of it moving up and down. At the same time, the needle fixing method is basically to hold the head of the glue canister or Luer connector tightly, and then connect the needle to the glue canister or Luer with threads. This can lead to risks such as non-vertical installation and positional deviation.

[0004] Existing technology has flaws and needs improvement. Utility Model Content

[0005] To address the shortcomings of current technology, this invention provides a device for fixing glue buckets and needles.

[0006] The present invention provides a device for fixing a glue container and a needle, comprising a fixing frame, a glue container, a fixing component, and a needle unit.

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1 - As shown in the figure: A device for fixing glue buckets and needles includes a fixing frame 1, a glue bucket 2, a fixing component 3, and a needle unit 4. A limiting seat 7 and a fixing component 3 are respectively provided on one side of the fixing frame 1. The limiting seat 7 and the fixing component 3 are arranged in parallel from bottom to top. The glue bucket 2 is arranged to pass through the fixing component 3 and the limiting seat 7 from top to bottom. An adapter 6 is installed at the top of the glue bucket 2, and the bottom of the glue bucket 2 is connected to the needle unit 4.

[0026] It should be noted that the glue bucket 2 is secured by a rubber clamp, which is stable. The clamp of the glue bucket 2 uses the mating surface of the fixing component 3 to cooperate with the hinge, making glue replacement convenient and quick. At the same time, in the needle unit 4, the needle is fixed by the needle fixing seat 41, which is stable. The needle unit 4 is also equipped with a needle fixing seat 41, which adds a needle fastening pin to prevent the needle from retracting.

[0027] Preferably, the fixing component 3 includes a first card sleeve 31, a second card sleeve 32, a card sleeve hinge 33, and a card sleeve hinge 34. A protruding limiting strip 11 is provided on one side of the first card sleeve 31, and the protruding limiting strip 11 is provided inside the fixing frame 1. One end of the card sleeve hinge 33 and one end of the card sleeve hinge 34 are respectively installed at both ends of the first card sleeve 31. The other end of the card sleeve hinge 33 is provided on one end of the second card sleeve 32, and the other end of the card sleeve hinge 34 is movably connected to the other end of the second card sleeve 32.

[0028] It should be noted that the first ferrule 31 and the second ferrule 32 engage to form a through hole for placing the glue bucket 2. In the non-working state, the ferrule hinge 34 is loosened, making the through hole between the first ferrule 31 and the second ferrule 32 larger, allowing the glue bucket 2 to be replaced and disassembled. In the working state, the ferrule hinge 34 is tightened, making the through hole between the first ferrule 31 and the second ferrule 32 smaller, securing the glue bucket 2 installed inside and preventing it from shaking during dispensing, thus avoiding the risk of vertical movement.

[0029] Preferably, a concave groove 12 is provided on one side of the fixing frame 1, and the concave groove 12 works in conjunction with the protruding limiting strip 11.

[0030] It should be noted that the raised limiting strip 11 can move up and down within the concave sliding groove 12, which can fix the glue buckets 2 of different lengths and sizes, and avoid the situation where the glue buckets 2 of different lengths cannot be fixed in place.

[0031] Preferably, the needle unit 4 includes a needle holder 41, a dispensing needle 42, and a needle fastening screw 43. The needle holder 41 is located at the lower end of the limiting seat 7. One end of the dispensing needle 42 is connected to the bottom end of the glue barrel 2 inside the needle holder 41, and the other end of the dispensing needle 42 passes through the needle holder 41. The needle fastening screw 43 is installed on one side of the needle holder 41.

[0032] It should be noted that the glue bucket 2 performs the glue dispensing operation through the dispensing needle 42, while the needle fastening screw 43 is used to fasten the dispensing needle 42 and prevent the needle from retracting.

[0033] Preferably, a through-hole is provided on one side of the needle holder 41, and the needle fastening screw 43 is disposed in the threaded hole.

[0034] It should be noted that the needle fastening screw 43 fastens the dispensing needle 42 by rotating it in the threaded hole, thereby preventing the dispensing needle 42 from retracting.

[0035] Preferably, a sensing seat is installed on one side of the limiting seat 7, and a sensor 5 is installed on the sensing seat.

[0036] It should be noted that the sensor 5 is used to sense the amount of glue dispensed into the glue bucket 2. When there is no glue in the glue bucket 2, the sensor 5 will issue an alarm prompting the glue bucket 2 to be replaced.

[0037] Preferably, a through-type retaining ring 13 is provided in the middle of the limiting seat 7, and the retaining rings 13 are arranged in descending order from top to bottom.

[0038] It should be noted that the retaining ring 13 is used to hold the glue bucket 2. The bottom of the glue bucket 2 is connected to the needle unit 4 downwards. The retaining ring 13 is set in a decreasing manner, which can effectively make the glue in the glue bucket 2 fall down and prevent the glue in the glue bucket 2 from clogging.

[0039] Preferably, the inner walls of both the first card sleeve 31 and the second card sleeve 32 are provided with elastic pads.

[0040] It should be noted that the elastic pads provided on the inner walls of the first card sleeve 31 and the second card sleeve 32 can effectively protect the glue bucket 2 from deformation due to compression while it is being tightened.

[0041] Furthermore, the inner walls of both the first card sleeve 31 and the second card sleeve 32 are curved, which allows for a better fit to the glue bucket 2.

[0042] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims of this utility model.
