[0023] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0024] like Figures 1 to 4 As shown, the utility model discloses a glue dispensing machine 100, which is used in the assembly production of PTC heaters to glue the parts together. Of course, according to production needs, it can also be applied to the production of other structures, such as the production of digital products (tablet computers, mobile phones, etc.).

[0025] The glue dispensing machine 100 of the present invention comprises a glue dispensing device 10, a glue pressing driver 20, a glue storage tube 30 and a glue mixing tube 40. The glue pressing driver 20 presses the glue in the glue storage tube 30 into the glue mixing tube 40, and then flows into the glue dispensing device 10, and the glue is output from the glue dispensing device 10 to dispense glue to the parts that need to be glued.

[0026] like Figure 3 and Figure 4 As shown, the present invention proposes an improvement on the structure of the glue dispensing device 10, which is described in detail below: The glue dispensing device 10 of the present invention includes a mounting bracket 11, a rotary driver 12, a glue outlet pipe 13, a clamping assembly 14, a glue outlet amount adjustment member 15 and a needle nozzle 16. The rotary driver 12 and the clamping assembly 14 are respectively mounted on the mounting bracket 11. The glue outlet pipe 13 has a rotary switch 131, and the rotary switch 131 is mounted on the output end of the rotary driver 12. The rotary driver 12 drives the rotary switch 131 to rotate to open or close the glue outlet pipe 13. The clamping assembly 14 mounts the glue outlet pipe 13 to the output end of the rotary driver 12 to fix the glue outlet pipe 13. One end of the glue outlet pipe 13 is a glue inlet end and the other opposite end is a glue outlet end, and the needle nozzle 16 is connected to the glue outlet end. The glue output amount adjusting member 15 is installed on the pressing assembly 14 and is adjustably arranged on the pressing assembly 14 . The glue output amount adjusting member 15 is pressed against the glue output pipe 13 . The glue output amount of the glue output pipe 13 is adjusted by adjusting the glue output amount adjusting member 15 to press the glue output pipe 13 to different degrees.

[0027] During operation, the glue in the mixing tube 40 flows into the glue outlet tube 13. Under the action of the glue outlet amount adjusting member 15, the flow rate of the glue is controlled, and finally flows out through the needle nozzle 16 to dispense glue to the spare parts. By adjusting the glue outlet amount adjusting member 15, the glue outlet amount adjusting member 15 can press the glue outlet tube 13 to different degrees, thereby adjusting the glue outlet amount of the glue outlet tube 13. The adjustment of the glue outlet amount is simple and fast. At the same time, by setting a rotary switch 131, the glue outlet tube 13 is closed after the glue dispensing is completed, which can reduce the waste of glue and avoid glue dripping to contaminate the equipment. If the rotary driver 12 drives the rotary switch 131 to rotate forward to open the glue outlet tube 13, the rotary driver 12 drives the rotary switch 131 to rotate reversely to close the glue outlet tube 13. The needle nozzle 16 controls the diameter of the output glue strip, thereby controlling the glue outlet amount.

[0028] Preferably, the glue output adjustment member 15 is a knob structure, but is not limited thereto. It is installed on the clamping assembly 14 by means of a threaded connection to achieve an adjustable setting. However, according to actual needs, it can also be installed by means of segmented snap-on connection or other adjustable methods.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the glue outlet pipe 13 includes a hard mounting head 132 and a hose 133. The hose 133 passes through the hard mounting head 132, and the first end of the rotary switch 131 passes through the hard mounting head 132 to form a valve head. When the rotary switch 131 rotates, the valve head rotates accordingly to control the on and off of the hose 133. The glue outlet amount adjusting member 15 is pressed against the hose 133. The glue outlet amount of the glue outlet pipe 13 is controlled by adjusting the glue outlet amount adjusting member 15 to press or loosen the hose 133. Figure 5 As shown, the hose 133 before compression is not deformed (solid line), and the tube diameter is large at this time. The rubber output adjustment member 15 is screwed in along the direction of arrow S to compress the hose 133. After compression, the hose 133 is deformed (dotted line), and the tube diameter is small at this time. The compression assembly 14 compresses the hard mounting head 132. The hard mounting head 132 is provided to facilitate the compression of the compression assembly 14 and avoid compression deformation of the hose 133. It should be noted that the material of the hard mounting head 132 is relatively hard, while the material of the hose 133 is relatively soft. Both can be made of plastic, but the hard mounting head 132 can also be made of metal.

[0030] like Figure 1 , Figure 3 and Figure 5 As shown, the clamping assembly 14 includes a clamping block 141 and a clamping locking knob 142. The clamping block 141 is mounted on the mounting bracket 11 through a mounting column 143, the clamping block 141 is against the hard mounting head 132, and the clamping locking knob 142 is mounted on the mounting column 143 and locks the clamping block 141, so that the clamping block 141 presses the hard mounting head 132, so that the clamping assembly 14 effectively positions the rubber hose 13.

[0031] Furthermore, a strip-shaped mounting groove 121 is provided at the output end of the rotary driver 12, and the second end of the rotary switch 131 forms a strip-shaped structure that is clamped in the strip-shaped mounting groove 121, so that the rotary switch 131 is effectively and reliably connected to the output end of the rotary driver 12. Of course, according to actual needs, the second end of the rotary switch 131 can also be set to a cross-shaped structure (corresponding to the cross groove), a star-shaped structure (corresponding to the star-shaped groove), etc., which can also achieve a reliable connection effect.

[0032] like Figures 1 to 4 As shown, the dispensing device 10 of the utility model further includes a needle nozzle fixing block 17 mounted on the mounting bracket 11, and the needle nozzle fixing block 17 includes a mounting end 171 directly opposite to the glue outlet pipe 13, and the mounting end 171 can be moved away from or close to the glue outlet pipe 13, and the needle nozzle 16 is mounted on the mounting end 171. By adjusting the mounting end 171 to move away from or close to the glue outlet pipe 13, the distance between the two is adjusted to adapt to needle nozzles 16 of different lengths. It is worth noting that different needle nozzles 16 output different glue strips, so that the glue output amount can be controlled by replacing different needle nozzles 16.

[0033] Furthermore, the needle nozzle fixing block 17 is provided with an adjustment strip hole 172 extending along the axis of the rubber outlet pipe 13, and a fixing block knob 173 is inserted into the adjustment strip hole 172 and locked to the mounting bracket 11, thereby locking the needle nozzle fixing block 17 to the mounting bracket 11. After loosening the fixing block knob 173, the needle nozzle fixing block 17 can slide along the axial direction of the rubber outlet pipe 13, so that the mounting end 171 is away from or close to the rubber outlet pipe 13. The adjustment of the needle nozzle fixing block 17 is simple and convenient, and the adjustment of the needle nozzle fixing block 17 is limited and guided.

[0034] like Figure 1 and Figure 2 As shown, the glue pressing driver 20 and the glue storage tube 30 are both installed on the mounting bracket 11. The glue pressing driver 20 is used to press the glue in the glue storage tube 30 toward the glue mixing tube 40, and the first end of the glue mixing tube 40 is connected to the glue storage tube 30 and the second end is connected to the glue inlet end of the glue outlet tube 13. The glue pressing driver 20 presses the glue out of the glue storage tube 30 to flow into the glue mixing tube 40, then flows through the glue outlet tube 13 and finally flows out from the needle nozzle 16. Preferably, the glue pressing driver 20 is selected as a cylinder, but it can also be applied as a linear motor or the like.

[0035] Preferably, the mounting bracket 11 of the present invention is a plate, but is not limited thereto, and can also be applied as a truss, etc. If the front and back sides of the mounting bracket 11 are distinguished, in the present invention, the glue pressing driver 20 is arranged on the back side of the mounting bracket 11, and the remaining structures are mostly arranged on the front side of the mounting bracket 11 to optimize the structural design, but are not limited to this structural layout. In order to make the output end of the glue pressing driver 20 slide more stably and smoothly, a guide rail 111 is installed on the front side of the mounting bracket 11, and the output end of the glue pressing driver 20 is slidably installed on the guide rail 111.

[0036] like Figure 1 As shown, further, the glue dispensing machine 100 of the utility model further includes a quick clamp 50 installed on the mounting bracket 11, and the glue storage tube 30 is locked between the quick clamp 50 and the mounting bracket 11. The quick clamp 50 can be used to easily and quickly replace and lock the glue storage tube 30. The quick clamp 50 can adopt the existing structure, and its structure is not described in detail here.

[0037] like Figure 1 As shown, the glue dispensing machine 100 of the present invention also includes a glue storage tube fixing block 60 installed on the mounting bracket 11. The glue storage tube 30 is installed on the glue storage tube fixing block 60, and the glue storage tube 30 can be installed on the glue storage tube fixing block 60 by parallel connection, clamping or even screw locking. The glue storage tube fixing block 60 is provided with a mounting notch 61, and the first end of the mixing glue tube 40 is clamped in the mounting notch 61 and is connected with the glue storage tube 30. The mixing glue tube 40 is clamped into the mounting notch 61 to limit the position, which reduces the influence of vibration, scratching and shaking, makes the glue discharge more stable, and also helps to improve the overall stability of the glue dispensing machine 100. The mounting notch 61 is roughly a square notch, but is not limited to this. The mixing glue tube 40 is connected with the glue storage tube 30 through a hose, a joint, etc.

[0038] Furthermore, the quick clamp 50 is locked with two glue storage tubes 30, and the mixing tube 40 is connected to the two glue storage tubes 30. The two glue storage tubes 30 can be respectively loaded with different glues, and the two different glues are mixed in the mixing tube 40 to output the mixed glue. In order to improve the mixing effect of the glue, the tube core of the mixing tube 40 is a spiral structure. Of course, according to needs, the two glue storage tubes 30 can also be loaded with the same glue.

[0039] The following briefly introduces the working process of the glue dispensing machine 100 of the present utility model:

[0040] The glue pressing driver 20 presses out the glue in the glue storage tube 30, and the pressed glue flows into the glue outlet tube 13 after being mixed in the glue mixing tube 40. The flow rate of the glue flowing out of the glue outlet tube 13 is adjusted by the glue outlet amount adjusting member 15, and finally flows out from the needle nozzle 16 to apply the glue to the parts. After the glue dispensing is completed, the rotary driver 12 drives the rotary switch 131 to reverse to close the glue outlet tube 13, thereby preventing the glue from flowing out.

[0041] The above disclosure is only a preferred example of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
