This solution only requires cutting after the bottom of the inner glue tube automatically extends, which is not only convenient and quick but also does not damage the dispensing head, making it highly practical.

Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to an automatic dispensing machine for circuit boards. Background Technology

[0002] Dispensing machines, also known as glue coating machines, dripping machines, glue spraying machines, or potting machines, are automated machines specifically designed to control fluids and apply them to the surface or interior of products. They can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and prevent stringing, leakage, and dripping. Dispensing machines are mainly used in product manufacturing processes to accurately dispense, inject, coat, or drip glue, applying it to precise locations on each product. They can be used to apply dots, lines, circles, or arcs.

[0003] After the existing automatic dispensing machine for circuit boards stops working, the glue outlet often solidifies, requiring manual unblocking before resuming operation. Conventional unblocking involves inserting a foreign object into the dispensing outlet to pick out the solidified material, or inserting a foreign object and then using subsequent glue to expel the solidified material. However, both of these methods may damage the dispensing outlet and are cumbersome and not conducive to efficient operation. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An automatic circuit board dispensing machine includes: a body assembly and a dispensing assembly; wherein, the body assembly includes a lifting device mounted on the frame, a glue tank disposed within the frame, a glue pump fixed below the lifting device, and a glue delivery pipe connected between the glue tank and the glue pump; the dispensing assembly is disposed on the glue pump, and the dispensing assembly includes a glue outlet pipe connected to the bottom of the glue pump, a movable pressure plate fitted outside the glue outlet pipe, an inner liner glue pipe fitted inside the glue outlet pipe and located below the movable pressure plate, an electric telescopic rod mounted on the glue pump and having its drive end passing through the movable pressure plate, a mounting ring adjustablely fixed to the drive end of the electric telescopic rod, a glue outlet head fixed inside the mounting ring and fitted outside the inner liner glue pipe, and mating blocks and locking grooves respectively disposed at both ends of the inner liner glue pipe and adapted to each other.

[0007] In a preferred embodiment, the present invention can be further configured such that: a lubricating oil box is connected between the glue pump and the glue outlet pipe, and a lubricating oil groove communicating with the lubricating oil box is provided on the glue outlet pipe.

[0008] In a preferred embodiment, the present invention can be further configured such that the bottom of the lubricating oil groove is higher than the bottom of the dispensing tube.

[0009] In a preferred embodiment, the present invention can be further configured such that: the mounting ring has a through hole through which the end of the electric telescopic rod passes, and a fastening bolt is threadedly connected to the side of the through hole.

[0010] In a preferred embodiment, the present invention can be further configured such that the movable pressure plate and the dispensing head are respectively provided with limiting rings located outside the inner lining tube.

[0011] In a preferred embodiment, the present invention can be further configured such that the docking block has a rhomboid structure and that adaptation holes are provided on both sides of the docking block.

[0012] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] This invention utilizes a dispensing assembly to place the inner lining tube inside the dispensing head. After the machine stops, the bottom of the dispensing head solidifies, but the solidified material remains on the bottom of the inner lining tube. When operation is required, the electric telescopic rod retracts, causing the movable pressure plate to push the inner lining tube into the dispensing head. This allows the bottom of the inner lining tube, along with the solidified material, to extend beyond the bottom of the dispensing head. At this point, the extended inner lining tube can be cut off to complete the unblocking process. This solution only requires cutting after the inner lining tube automatically extends from the bottom, making it convenient, quick, and without damaging the dispensing head, thus demonstrating high practicality.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of an automatic dispensing machine for circuit boards provided by this utility model.

[0024] Combination Figure 1-5 As shown, the present invention provides an automatic dispensing machine for circuit boards, comprising: a body assembly 100 and a dispensing assembly 200; wherein, the body assembly 100 includes a frame 110, a lifter 120 mounted on the frame 110, a glue tank 130 disposed within the frame 110, a glue pump 140 fixed below the lifter 120, and a glue delivery pipe 150 connected between the glue tank 130 and the glue pump 140.

[0025] The dispensing assembly 200 is mounted on the glue pump 140. The dispensing assembly 200 includes a dispensing tube 210 connected to the bottom of the glue pump 140, a movable pressure plate 220 fitted around the dispensing tube 210, an inner liner tube 230 fitted around the dispensing tube 210 and located below the movable pressure plate 220, an electric telescopic rod 240 mounted on the glue pump 140 with its drive end passing through the movable pressure plate 220, a mounting ring 250 adjustablely fixed to the drive end of the electric telescopic rod 240, a dispensing head 260 fixed inside the mounting ring 250 and fitted around the inner liner tube 230, and mating joints respectively located at both ends of the inner liner tube 230 and compatible with each other. Block 270 and the snap-fit ​​groove 280, through the dispensing assembly 200, allow the inner lining tube 230 to be placed inside the dispensing head 260. After the machine stops, the bottom of the dispensing head 260 solidifies, but the solidified material is all on the bottom of the inner lining tube 230. When operation is required, the electric telescopic rod 240 is retracted, causing the movable pressure plate 220 to push the inner lining tube 230 into the dispensing head 260, thereby causing the bottom of the inner lining tube 230, along with the solidified material, to extend outside the bottom of the dispensing head 260. At this time, the extended inner lining tube 230 can be cut off to complete the unblocking. This solution only requires cutting after the bottom of the inner lining tube 230 automatically extends, which is not only convenient and quick, but also will not damage the dispensing head 260.

[0026] Specifically, a lubricating oil box 141 is connected between the glue pump 140 and the glue outlet pipe 210, and a lubricating oil groove 211 is provided on the glue outlet pipe 210 that communicates with the lubricating oil box 141. Through the lubricating oil box 141 and the lubricating oil groove 211, the glue in the lubricating oil box 141 can be coated on the outside of the glue outlet pipe 210 through the lubricating oil groove 211, and then adhere to the inside of the inner lining tube 230. When the movable pressure plate 220 pushes the inner lining tube 230 to move on the outside of the glue outlet pipe 210, it is smoother, which facilitates the displacement of the inner lining tube 230. In addition, the lubricating oil can prevent excessive glue residue on the inner wall of the inner lining tube 230, ensuring the smoothness of glue dispensing.

[0027] Furthermore, the bottom of the lubricating oil groove 211 is higher than the bottom of the dispensing pipe 210, which can prevent lubricating oil from flowing from the bottom of the dispensing pipe 210 into the glue, which is more reasonable.

[0028] On the other hand, the mounting ring 250 has a through hole for the end of the electric telescopic rod 240 to pass through, and the through hole is threaded with a fastening bolt 251. The position of the mounting ring 250 on the drive end of the electric telescopic rod 240 can be adjusted by using the fastening bolt 251. At the same time, it is convenient to remove the dispensing head 260 and put a new inner lining tube 230 on the outside of the dispensing tube 210 for use.

[0029] It should be noted that the movable pressure plate 220 and the dispensing head 260 are respectively provided with a limiting ring 221 located outside the inner lining tube 230. The limiting ring 221 can position the inner lining tube 230 and improve its stability.

[0030] Furthermore, the docking block 270 has a rhomboid structure, and the docking block 270 has adaptation holes 271 on both sides, which allows the docking block 270 to be inserted into the snap-fit ​​groove 280 after the two inner lining tubes 230 are docked. The adaptation holes 271 can deform themselves when the docking block 270 is inserted, making it easier to enter the snap-fit ​​groove 280.

[0031] The working principle and usage process of this utility model are as follows: First, the inner lining tube 230 is placed inside the dispensing head 260, and the bottom ends of the two are flush. When the machine stops, the bottom of the dispensing head 260 solidifies, but the solidified material is all on the bottom of the inner lining tube 230. When operation is required, the electric telescopic rod 240 is used to drive the retraction, thereby causing the movable pressure plate 220 to push the inner lining tube 230 into the dispensing head 260, so that the bottom of the inner lining tube 230, along with the solidified material, extends out to the bottom end of the dispensing head 260. At this time, the extended inner lining tube 230 is cut off to complete the unblocking.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
