Description

Technical Field

[0001] This utility model relates to the field of circuit board processing equipment technology, and in particular to a dispensing machine for circuit board processing. Background Technology

[0002] In the production and processing of circuit boards, the dispensing process is a key step to ensure the stable installation and electrical performance of electronic components.

[0003] Traditional circuit board dispensing machines often suffer from problems such as complex structure, inconvenient installation and disassembly of dispensing heads, uneven glue distribution, and difficulty in achieving simultaneous operation of multiple glue paths.

[0004] Some dispensing machines have fixed dispensing components, which makes it impossible to quickly change to a suitable dispensing sleeve when facing different dispensing needs, affecting production efficiency. In addition, during the transmission of glue, uneven pressure and poor backflow are prone to occur, resulting in unstable dispensing quality and a high product defect rate.

[0005] Therefore, this utility model proposes a dispensing machine for circuit board processing. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dispensing machine for circuit board processing.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a dispensing machine for circuit board processing, comprising a dispensing assembly, wherein the dispensing assembly consists of a dispensing sleeve and a diverting sleeve, wherein three dispensing sleeves are provided in a ring arrangement, and further comprising:

[0008] The mounting assembly consists of a mounting sleeve mounted on a distribution sleeve and a dispensing mounting sleeve mounted on a dispensing sleeve. A connecting rod is provided between the dispensing mounting sleeve and the mounting sleeve. A triangular fixing claw is provided at the bottom of the dispensing mounting sleeve, and a slot is provided at the top of the dispensing mounting sleeve.

[0009] Furthermore, the dispensing sleeve is provided with an installation plate, and the bottom of the installation plate is provided with installation pins. There are three installation pins in total, and the three installation pins are respectively engaged with the three slots.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the three mounting pins at the bottom of the mounting plate are connected to the slot at the top of the dispensing mounting sleeve through a triangular layout, and the friction generated by the interference fit is used to achieve quick fastening. Vertical insertion and removal can complete the disassembly and assembly, which shortens the sleeve replacement time, improves efficiency compared with traditional bolt connection, ensures the accuracy of dispensing position, and eliminates the problem of thread wear, reducing maintenance difficulty and cost.

[0011] Furthermore, the top of the dispensing sleeve is provided with a connecting pipe that communicates with the diverting sleeve, and the bottom of the diverting sleeve is provided with a peristaltic pump, the input end of which is fixedly connected to a glue inlet pipe.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the peristaltic pump delivers the glue to the distribution sleeve by squeezing it into the glue tube, and then distributes it to each dispensing sleeve through the connecting pipe. This design utilizes the flexible delivery characteristics of the peristaltic pump to avoid direct contact between the glue and the pump body, thereby achieving continuous and stable glue delivery, ensuring that the performance of the glue is not affected during delivery, adapting to the delivery needs of various glue types, effectively preventing the glue from curing and clogging the pipes, and ensuring the smooth progress of the dispensing operation.

[0013] Furthermore, the top of the diverter sleeve is provided with an output end, and an exhaust pipe and a return pipe are provided on one side of the output end. The output end of the return pipe is fixedly connected to the bottom of the diverter sleeve.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the exhaust pipe at the top output end of the diverter sleeve can discharge the gas in the adhesive, avoiding air bubbles from affecting the dispensing quality. The return pipe returns excess adhesive to the bottom of the sleeve, forming a circulation path to ensure that the pressure of the adhesive is balanced in the sleeve. This design effectively improves the fluidity and stability of the adhesive through the dual mechanism of gas discharge and adhesive circulation, prevents adhesive sedimentation or excessive local pressure, ensures the consistency of adhesive performance during continuous dispensing, and adapts to the dispensing needs under different working conditions.

[0015] Furthermore, a drive mounting plate is provided above the mounting sleeve, and a connecting plate is provided between the drive mounting plate and the mounting sleeve, the connecting plate being arranged in a ring.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the drive mounting plate is connected to the mounting sleeve through the ring-shaped connecting plates to form a stable support structure. The ring layout ensures that the driving force is evenly distributed around the mounting sleeve, ensuring that the dispensing assembly remains balanced during movement and avoiding shaking due to uneven force. This design enhances the integrity and reliability of the mounting structure, enabling the drive mounting plate to stably transmit external driving force, drive the dispensing assembly to move accurately, adapt to the needs of high-speed dispensing operations, and facilitate connection with different drive devices, improving the installation adaptability of the equipment.

[0017] Furthermore, the top of the drive mounting plate is provided with mounting brackets, and there are four mounting brackets in total, which are arranged in a ring, and the distance between two adjacent mounting brackets is equal.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: The four equally spaced annularly distributed mounting brackets on the top of the drive mounting plate are firmly connected to the external drive mechanism through evenly distributed connection points, forming a symmetrical force structure. This ensures that the driving force is evenly transmitted along the central axis, effectively reducing lateral offset and torque imbalance, and enabling the dispensing assembly to maintain a stable posture during high-speed movement. This avoids the dispensing accuracy being affected by vibration or shaking. At the same time, the standardized installation interface design improves compatibility with different drive systems, simplifies the equipment integration process, and enhances the reliability and maintainability of the overall structure.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the mounting assembly consists of a mounting sleeve on the diverter sleeve and a dispensing mounting sleeve on the dispensing sleeve. The two are connected by a connecting rod to form a stable frame structure. The triangular fixing claw at the bottom of the dispensing mounting sleeve can tightly engage with the dispensing sleeve, and the top slot engages with the mounting pin of the dispensing sleeve, enabling quick positioning and fixing of the dispensing sleeve. This design, through the support of the connecting rod and the tight engagement of the triangular fixing claw, ensures that the dispensing sleeve remains stable during operation, preventing shaking from affecting dispensing accuracy. At the same time, the engaging structure of the slot and the pin facilitates the disassembly and assembly of the dispensing sleeve, allowing for quick replacement of the sleeve according to different dispensing needs, thus improving the practicality and ease of operation of the equipment.
