Description

Technical Field

[0001] The invention relates to the field of LED production, and in particular to a glue dispensing device for LED production. Background Art

[0002] Glue dispensing machine is also called glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc. It is an automated machine that controls fluids and drips and applies fluids to the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no glue leakage, no glue dripping. Glue dispensing machine is mainly used for glue, paint and other liquids in product processes to accurately dispense, inject, apply and drip to the precise position of each product, and can be used to achieve dotting, drawing lines, circles or arcs;

[0003] When using the glue dispenser for LED lamp holders, the glue dispenser performs reciprocating motion, and the glue dispenser needle of the glue dispenser is very thin. Therefore, every time the glue dispenser stops in the reciprocating motion, the glue dispenser needle is prone to vibration, which leads to deviations in the glue dispense point. As a result, there is a glue dispenser for LED lamp holder production with patent number CN219745348U, but it has the following defects, such as: the fixed sleeve is in large area with the glue dispenser needle, which is not conducive to improving the safety of the glue dispenser needle when the two groups rub against each other, and the glue dispenser gun structure has been finalized when the manufacturer produces it, which is not conducive to modification by subsequent buyers. That is, in the prior art, the glue dispenser gun has an open thread groove, because it is easy to penetrate the glue dispenser gun due to insufficient thickness of the side wall during subsequent slotting, or the thread groove depth is not up to standard, which affects the subsequent connection stability. Summary of the invention

[0004] The purpose of the present invention is to provide a glue dispensing device for LED production.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A glue dispensing device for LED production includes a glue dispensing gun arranged on a glue dispensing machine, wherein a glue dispensing needle is arranged at the bottom of the glue dispensing gun:

[0007] The dispensing needle is covered with multiple sets of protective mechanisms, wherein the multiple sets of protective mechanisms are arranged in series up and down, and the uppermost protective mechanism is connected to the cylinder covered with the dispensing gun through a connecting part, and a circle of arched parts are arched outward on the side wall of the cylinder, wherein an arc-shaped seat buckled on the dispensing gun is arranged in the arched part, and a screw is fixed on the outer wall of the arc-shaped seat through a rolling bearing, and a screw hole for the screw to pass through is arranged on the side wall of the arched part;

[0008] The protection mechanism comprises a fixed cylinder, on the inner side wall of which a rubber grid plate is spirally arranged and sleeved on the dispensing needle, wherein flanges are arranged at both ends of the fixed cylinder, and two corresponding sets of flanges are connected by bolts.

[0009] Preferably, a metal woven mesh is provided in the side wall of the grid plate, one side wall of the grid plate is tightly attached to the outer wall of the dispensing needle, and a strip groove for accommodating the other end of the grid plate is provided on the inner wall of the fixing tube, wherein the grid plate is adhesively fixed to the side wall of the strip groove.

[0010] Preferably, a rubber anti-slip layer is provided on the inner side wall of the arc-shaped seat.

[0011] Preferably, a screw tube which is sleeved on the screw rod is arranged in the opening of the arched portion, wherein the screw rod is fixed to the screw tube and the screw hole by screw connection.

[0012] Preferably, a driving block is provided at the end of the screw rod outside the arched portion.

[0013] Preferably, the fixing cylinder, the connecting portion and the cylinder are all made of stainless steel.

[0014] The beneficial effect of the present invention is that the present invention covers the cylinder on the dispensing gun, and then drives the fixed cylinder and the grid plate to cover the dispensing needle, wherein by rotating the screw to make it rotate in the screw tube and the screw hole, the arc seat is driven to move and fit tightly on the dispensing gun, thereby realizing the locking and fixing of the cylinder and the protective mechanism on the dispensing gun, without the need to provide a threaded groove on the dispensing gun as in the past, so as to improve the safety of the dispensing gun, and at the same time ensure the connection stability between the cylinder and the protective mechanism and the dispensing gun, wherein the spirally arranged grid plate not only plays a fixing role in the different directions of the upper and lower areas of the dispensing needle, but also can minimize the contact area with the dispensing needle to maximize the reduction of the friction generated between the two, so as to improve its safety and reduce the friction generated between the two, and because the rubber grid plates are of a certain telescopic type, they can play a certain buffering role when the dispensing needle shakes.

[0017] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0018] A glue dispensing device for LED production includes a glue dispensing gun 1 arranged on a glue dispensing machine, wherein a glue dispensing needle 2 is arranged at the bottom of the glue dispensing gun 1:

[0019] The dispensing needle 2 is covered with a plurality of protective mechanisms 3, wherein the plurality of protective mechanisms 3 are arranged in series up and down, and the uppermost protective mechanism 3 is connected to a cylinder 4 covered with the dispensing gun 1 through a connecting portion 5, and a circle of arched portion 6 is arched outward on the side wall of the cylinder 4, wherein an arc seat 7 buckled on the dispensing gun 1 is arranged in the arched portion 6, and a rubber anti-skid layer is arranged on the inner side wall of the arc seat 7, and a screw 9 is fixed on the outer wall of the arc seat 7 through a rolling bearing 8, and a screw hole for the screw 9 to pass through is arranged on the side wall of the arched portion 6;

[0020] The protection mechanism 3 includes a fixed cylinder 31, on the inner wall of which a rubber grid plate 32 is spirally arranged and sleeved on the dispensing needle 2, wherein flanges 33 are arranged at both ends of the fixed cylinder 31, and the upper and lower corresponding sets of flanges 33 are connected by bolts.

[0021] In this embodiment, a metal woven mesh is provided in the side wall of the grid plate 32, one side wall of the grid plate 32 is tightly attached to the outer wall of the dispensing needle 2, and a strip groove for accommodating the other end of the grid plate 32 is provided on the inner wall of the fixing tube 31, wherein the grid plate 32 is adhesively fixed to the side wall of the strip groove.

[0022] like Figure 1 As shown, a screw tube 10 which is sleeved on the screw rod 9 is arranged in the opening of the arched portion 6, wherein the screw rod 9 is screwed and fixed with the screw tube 10 and the screw hole.

[0023] like Figure 1 As shown, a driving block 11 is provided at the end of the screw rod 9 outside the arched portion 6. The driving block 11 facilitates the screw rod 9 to be rotated.

[0024] In this embodiment, the fixing cylinder 31 , the connecting portion 5 and the cylinder 4 are all made of stainless steel.

[0025] The method of using the present invention is as follows: the cylinder 4 is placed on the glue gun 1, and then the fixed cylinder 31 and the grid plate 32 are placed on the glue needle 2, wherein the screw 9 is rotated to rotate in the rolling bearing 8, the screw tube 10 and the screw hole, and the arc seat 7 is driven to move and fit closely on the glue gun 1, thereby locking and fixing the cylinder 4 and the protective mechanism 3 on the glue gun 1, without the need to provide a threaded groove on the glue gun 1 as in the past, so as to improve the safety of the glue gun 1, and also ensure the stability of the connection between the cylinder 4 and the protective mechanism 3 and the glue gun 1;
