The user places the electronic components that need to be glued on the support plate, and the telescopic cylinder pushes the support plate to make the electronic components close to the dispensing mechanism, and the dispensing mechanism performs a dispensing operation on them. When cleaning is required, the user pours clean water and starts the motor to clean, so that the device will not be affected by the mixing of multiple raw materials. Dispensing effect;

[0004] Since the liquid outlet of the glue injection head is in contact with the outside world, when the glue dispensing machine temporarily stops injecting glue, the liquid outlet of the glue injection head will be blocked by the solidified glue, thereby affecting the liquid outlet. However, this patent cannot solve this problem. Utility Model Content

[0005] The purpose of the utility model is to provide a glue dispensing device for manufacturing electronic components to solve the problems raised in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a glue dispensing device for manufacturing electronic components, comprising a console, a mounting frame is fixedly arranged on the top of the console, a glue bin is fixedly installed between the mounting frames, and the bottom end of the glue bin is integrated and connected with a glue discharge nozzle, and also includes:

[0007] An extrusion component, which is used for extruding glue and is fixedly arranged inside the glue tank;

[0008] The extrusion assembly includes a hydraulic cylinder, which is embedded and installed on the top of the glue bin. The telescopic end of the glue bin slides through the top plate of the glue bin and is fixedly connected to a moving rod. The bottom end of the moving rod is fixedly connected to an extrusion plate. The bottom of the extrusion plate is fixedly connected to a needle body used to poke through the discharge end of the glue discharge nozzle that is blocked due to glue solidification. The glue discharge nozzle includes a straight vertical portion and an inverted triangle-shaped glue injection portion. The vertical portion of the glue discharge nozzle is arranged on the top of the glue injection portion, and the outer diameter of the extrusion plate is equal to the inner diameter of the vertical portion of the glue discharge nozzle.

[0009] A stirring component is used to stir the glue liquid and is rotatably connected under the inner top plate of the glue bin. The stirring component is movably arranged outside the hydraulic cylinder.

[0010] Preferably, the glue bin comprises a heat-insulating outer shell, a heat-conducting inner shell is fixedly arranged inside the heat-insulating outer shell, and a heating layer is arranged between the heat-insulating outer shell and the heat-conducting inner shell.

[0011] Preferably, the stirring assembly includes a rotating drum, the top end of which is rotatably connected to the inner top plate of the glue bin, the rotating drum is movably sleeved on the outside of the moving rod, the inner wall of the rotating drum is provided with a spiral groove, a slider is slidably installed inside the spiral groove, one end of the slider is movably extended to the outside of the spiral groove, and is fixedly connected to the outer wall of the moving rod, and a plurality of groups of stirring blades are fixedly provided on the outer wall of the rotating drum.

[0012] Preferably, the displacement of the extrusion plate to the junction of the vertical portion of the glue outlet nozzle and the glue injection portion is equal to the displacement of the bottom end of the needle body to the glue injection port of the glue outlet nozzle.

[0013] Preferably, a baffle is fixedly provided 1 mm above the bottom end of the needle body, and the outer portion of the baffle is matched with the inner wall 1 mm above the glue injection port.

[0014] Preferably, a cover body is provided through the top plate of the glue bin.

[0015] Preferably, the control console is built with a control unit, and the control unit is electrically connected to the hydraulic cylinder and the heating layer.

[0016] Preferably, the outer shell of the glue discharge nozzle is made of a heat-insulating material.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model drives the extrusion plate to move up by the hydraulic cylinder. When the extrusion plate is separated from the glue discharge nozzle, the glue in the glue tank flows into the glue discharge nozzle, and the hydraulic cylinder drives the extrusion plate to move down. The extrusion plate can assist in squeezing the glue downward, so that the glue is squeezed out from the small glue injection port of the glue discharge nozzle more quickly. The hydraulic cylinder drives the extrusion plate to move up and down regularly through the moving rod, thereby ensuring the continuous dispensing work;

[0019] 2. The utility model sets a needle body at the bottom of the extrusion plate, and the needle body moves downward with the extrusion plate, thereby continuously poking through the glue injection port to prevent the glue from being blocked at the glue injection port. Moreover, because the needle body is small, under the same pressure, the glue injection port can be squeezed through by squeezing the glue out of the liquid. The needle body can give a greater pressure to the solidification part. Therefore, under the premise of opening the glue injection port, the pressure that the hydraulic cylinder needs to give is relatively smaller, thereby reducing the electricity cost;

[0020] 3. The utility model sets a needle body. When the device stops working, the tip of the needle body is just at the glue injection port and is condensed with glue on the inner wall of the glue injection port. However, when re-dispensing glue, the hydraulic cylinder will drive the extrusion plate to move up. Since the needle body is thin and the contact area with the glue is small, it is easy to be driven up by the needle body, thereby tearing the solidified glue and reopening the glue injection port, without spending extra manpower to clean the glue injection port;

[0021] 4. The utility model blocks most of the glue inside the glue tank by the extrusion plate, and arranges a baffle plate above the tip of the needle body. When the needle body is at the glue injection port, the baffle plate also fits exactly with the inner wall above the glue injection port of the glue discharge nozzle, and separates the glue injection part of the glue discharge nozzle from the glue injection port, thereby greatly reducing the glue outflow from the glue injection part;

[0022] 5. The utility model sets the baffle plate 1mm above the tip of the needle body, which can not only greatly reduce the outflow of glue, but also the outer diameter of the needle body is correspondingly smaller, so when it moves up and down, the resistance between it and the glue is also smaller, thereby preventing the baffle plate from being damaged due to excessive resistance;

[0023] 6. The utility model sets a rotating drum. When the moving rod moves up and down, the slider moves accordingly. Since the outer end of the slider is slidably mounted inside the spiral groove provided on the inner wall of the rotating drum, the slider drives the rotating drum to rotate. The rotation of the rotating drum drives the stirring blade to rotate and stir the glue inside the glue bin, so that the glue is heated more evenly.

[0024] 7. The utility model heats the glue inside the glue bin by arranging a heating layer and maintains a constant temperature. A higher temperature can keep the glue in a flowing state, thereby reducing the pressure required for liquid discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figures 1 to 5 , the utility model provides a technical solution:

[0034] A glue dispensing device for manufacturing electronic components includes a control console 1, a mounting frame 11 is fixedly arranged on the top of the control console 1, a glue bin 2 is fixedly installed between the mounting frames 11, and a glue discharge nozzle 3 is integrally connected to the bottom end of the glue bin 2, and also includes:

[0035] An extrusion component, which is used to extrude glue and is fixedly arranged inside the glue tank 2;

[0036] The extrusion assembly includes a hydraulic cylinder 4, which is embedded and installed on the top of the glue bin 2. The telescopic end of the glue bin 2 slides through the top plate of the glue bin 2 and is fixedly connected to a moving rod 5. The bottom end of the moving rod 5 is fixedly connected to an extrusion plate 51. The bottom of the extrusion plate 51 is fixedly connected to a needle body 52 for poking through the discharge end of the glue nozzle 3 blocked by glue solidification. The glue nozzle 3 includes a straight cylindrical vertical portion and an inverted triangle-shaped glue injection portion. The vertical portion of the glue nozzle 3 is arranged on the top of the glue injection portion, and the outer diameter of the extrusion plate 51 is equal to the inner diameter of the vertical portion of the glue nozzle 3. The displacement of the extrusion plate 51 to the intersection of the vertical portion of the glue nozzle 3 and the glue injection portion is equal to the displacement of the bottom end of the needle body 52 to the glue injection port of the glue nozzle 3.

[0037] A stirring component, which is used to stir the glue liquid, is rotatably connected under the inner top plate of the glue bin 2 , and the stirring component is movably arranged outside the hydraulic cylinder 4 .

[0038] First embodiment

[0039] The glue bin 2 includes a heat-insulating outer shell 21, a heat-conducting inner shell 22 is fixedly arranged inside the heat-insulating outer shell 21, a heating layer 23 is arranged between the heat-insulating outer shell 21 and the heat-conducting inner shell 22, a cover body 24 is penetrated through the top plate of the glue bin 2, and a control unit is built into the control console 1. The control unit is electrically connected to the hydraulic cylinder 4 and the heating layer 23, and the outer shell of the glue discharge nozzle 3 is made of heat-insulating material.

[0040] Specifically, the control console 1 controls the heating layer 23 to start heating the glue inside the glue bin 2 and maintain a constant temperature. A higher temperature can keep the glue in a flowing state, thereby reducing the pressure required for liquid discharge.

[0041] Second embodiment

[0042] The stirring assembly includes a rotating drum 6, the top end of which is rotatably connected to the inner top plate of the glue bin 2, and the rotating drum 6 is movably sleeved on the outside of the moving rod 5. The inner wall of the rotating drum 6 is provided with a spiral groove 61, and a slider 62 is slidably installed inside the spiral groove 61. One end of the slider 62 is movably extended to the outside of the spiral groove 61 and is fixedly connected to the outer wall of the moving rod 5. The outer wall of the rotating drum 6 is fixedly provided with multiple groups of stirring blades 63.

[0043] Specifically, when the moving rod 5 moves up and down, the slider 62 moves accordingly. Since the outer end of the slider 62 is slidably installed inside the spiral groove 61 set on the inner wall of the rotating drum 6, the slider 62 will drive the rotating drum 6 to rotate. The rotation of the rotating drum 6 will drive the stirring blade 63 to rotate and stir the glue inside the glue bin 2, so that the glue is heated more evenly.

[0044] Third embodiment

[0045] A baffle 53 is fixedly provided 1 mm above the bottom end of the needle body 52 , and the outer portion of the baffle 53 is matched with the inner wall 1 mm above the glue injection port.

[0046] Specifically, when glue dispensing is stopped, although most of the glue inside the glue tank 2 is blocked by the extrusion plate 51, some glue remaining in the glue injection part of the glue discharge nozzle 3 will still flow out along the gap between the needle body 52 and the glue injection port, thereby causing a waste of glue. By setting a baffle 53 at a position above the tip of the needle body 52, when the needle body 52 is at the glue injection port, the baffle 53 also happens to fit the inner wall above the glue injection port of the glue discharge nozzle 3, and separates the glue injection part of the glue discharge nozzle 3 from the glue injection port, thereby greatly reducing the outflow of glue. By setting the baffle 53 1 mm above the tip of the needle body 52, not only can the outflow of glue be greatly reduced, but also because the inner diameter of the glue injection part of the glue discharge nozzle 3 gradually decreases from top to bottom, when the baffle 53 is set at a position relatively close to the glue injection port, the outer diameter of the needle body 52 is also correspondingly smaller, so when it moves up and down with the needle body 52, the resistance between it and the glue is also smaller.

[0047] Working principle: open the cover 24, add glue into the glue bin 2, control the heating layer 23 through the control console 1 to start heating the glue inside the glue bin 2 and keep a constant temperature. A higher temperature can make the glue flow, thereby reducing the pressure required for liquid discharge;

[0048] The initial state of the hydraulic cylinder 4 is that the telescopic end is extended, so that the extrusion plate 51 is located at the connection between the vertical part of the glue discharge nozzle 3 and the glue injection part. The outer diameter of the extrusion plate 51 is equal to the inner diameter at this point, so the glue inside the glue tank 2 is blocked to prevent the glue from leaking out when no glue dispensing is required. When glue dispensing is required, the electronic components are placed on the top of the control console 1, aligned with the glue injection port of the glue discharge nozzle 3, and then the control console 1 is controlled to open the hydraulic cylinder 4. The hydraulic cylinder 4 drives the extrusion plate 51 to move upward through the moving rod 5. When the extrusion plate 51 is separated from the glue discharge nozzle 3, the glue inside the glue tank 2 flows into the inside of the glue discharge nozzle 3. The hydraulic cylinder 4 drives the extrusion plate 51 to move downward through the moving rod 5. The extrusion plate 51 can assist in squeezing the glue downward, so that the glue is squeezed out from the small glue injection port of the glue discharge nozzle 3 faster. The hydraulic cylinder 4 drives the extrusion plate 51 to move up and down regularly through the moving rod 5, thereby ensuring the continuous progress of the glue dispensing work;

[0049] By arranging a needle body 52 at the bottom of the extrusion plate 51, the needle body 52 will move downward with the extrusion plate 51 each time, thereby continuously poking through the glue injection port, thereby preventing the glue from being blocked at the glue injection port. Moreover, since the needle body 52 is small, under the same pressure, the glue injection port can be squeezed through by squeezing out the glue liquid, and the needle body 52 can give a greater pressure to the solidification part. Therefore, under the premise of opening the glue injection port, the pressure that the hydraulic cylinder 4 needs to give is relatively smaller, thereby reducing the electricity cost.

[0050] In addition, when the glue dispensing work is stopped, although the glue tank 2 continues to heat the glue through the heating layer 23, and the glue nozzle 3 is also made of heat-insulating material, so that the glue inside is not easy to coagulate, the glue injection port of the glue nozzle 3 is a part that is in direct contact with the outside world, and the glue at this place is still very easy to solidify and block the glue injection port. By setting the needle body 52, when the device stops working, the tip of the needle body 52 is just at the glue injection port. Even if the needle body 52 and the inner wall of the glue injection port are coagulated by glue, when the work is restarted, the hydraulic cylinder 4 drives the extrusion plate 51 to move up. Since the needle body 52 is thin and the contact area with the glue is small, it is easily driven by the needle body 52 to move up, thereby tearing the solidified glue and reopening the glue injection port, without spending extra manpower to clean the glue injection port;

[0051] When the glue dispensing work is stopped, although most of the glue inside the glue tank 2 is blocked by the extrusion plate 51, some glue remaining in the glue injection part of the glue discharge nozzle 3 will still flow out along the gap between the needle body 52 and the glue injection port, thereby causing glue waste. By setting a baffle 53 at a position above the tip of the needle body 52, when the needle body 52 is at the glue injection port, the baffle 53 also fits exactly with the inner wall above the glue injection port of the glue discharge nozzle 3, separating the glue injection part of the glue discharge nozzle 3 from the glue injection port, thereby greatly reducing the outflow of glue. By setting the baffle 53 1 mm above the tip of the needle body 52, not only can the outflow of glue be greatly reduced, but also because the inner diameter of the glue injection part of the glue discharge nozzle 3 gradually decreases from top to bottom, when the baffle 53 is set at a position relatively close to the glue injection port, the outer diameter of the needle body 52 is also correspondingly smaller. Therefore, when it moves up and down with the needle body 52, the resistance between it and the glue is also smaller, thereby preventing the baffle 53 from being damaged due to excessive resistance.

[0052] When the moving rod 5 moves up and down, the slider 62 moves accordingly. Since the outer end of the slider 62 is slidably installed inside the spiral groove 61 set on the inner wall of the rotating drum 6, the slider 62 will drive the rotating drum 6 to rotate. The rotation of the rotating drum 6 will drive the stirring blade 63 to rotate and stir the glue inside the glue bin 2, so that the glue is heated more evenly.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
