Description

Technical Field

[0001] This utility model relates to the field of display screen production equipment technology, and in particular to a manual dispensing machine for display screen production. Background Technology

[0002] In the display manufacturing process, the dispensing process is a crucial step, as precise dispensing is required for aspects such as sealing the display frame, fixing chips, and assembling backlight modules.

[0003] Traditional manual dispensing machines have many drawbacks. On the one hand, operators manually control the glue gun, making it difficult to precisely control the glue amount, resulting in inconsistent glue dispensing amounts that affect product quality and consistency. On the other hand, for small display screen components, manual operation makes it difficult to ensure the accuracy of the glue dispensing position, which can easily lead to glue misalignment.

[0004] Existing manual dispensing machines typically lack effective mechanisms for adjusting adhesive flow and pressure, making them unable to adapt to dispensing requirements for adhesives of different viscosities, which greatly reduces production efficiency and yield.

[0005] Therefore, this utility model proposes a manual dispensing machine for display screen production. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a manual dispensing machine for display screen production.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a manual dispensing machine for display screen production, comprising:

[0008] The dispensing assembly consists of a dispensing tube, a threaded rod, and a pump head. The pump head is slidably connected inside the dispensing tube, the threaded rod is located on the top of the pump head, and a viewing glass is embedded in the dispensing tube.

[0009] The drive assembly consists of an inner drive disk and an outer drive disk positioned above the dispensing tube. The inner drive disk is located inside the outer drive disk, and a first tooth groove is provided on the outer side of the inner drive disk. The inner drive disk is meshed with the inner ring of the outer drive disk through the first tooth groove. A second tooth groove is provided on the outer side of the outer drive disk. A fixing rod is provided on one side of the second tooth groove on the dispensing tube, and a drive gear is rotatably connected to the fixing rod. The drive gear is meshed with the second tooth groove.

[0010] Furthermore, a sliding groove is provided on the inner drive disk between the two first tooth grooves, and a ball bearing is movably connected between the sliding groove and the inner ring of the outer drive disk, the ball bearing being distributed in a ring.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the sliding groove provided between the two first tooth grooves on the inner drive disk is movably connected to the inner ring of the outer drive disk with a ring-shaped distribution of rolling balls. This ingenious structure has significant beneficial effects. The rolling balls flexibly roll between the sliding groove and the inner ring of the outer drive disk, which greatly reduces operating friction, reduces energy loss, improves transmission efficiency, ensures stable operation of the drive disk, extends its service life, and effectively optimizes the overall performance of the equipment.

[0012] Furthermore, a limiting sliding post is provided on the dispensing tube below the external drive disk. The limiting sliding post is arranged in a ring, and the top of the limiting sliding post is slidably connected to the bottom of the external drive disk.

[0013] The beneficial effects of adopting the above-mentioned further solution are as follows: The limiting sliding posts arranged in a ring below the external drive disk on the dispensing tube, with their tops slidably connected to the bottom of the external drive disk, bring many benefits. On the one hand, the ring-shaped limiting sliding posts can effectively constrain the movement trajectory of the external drive disk, enhance its stability, and prevent deviation and shaking during operation. On the other hand, the sliding connection makes the external drive disk rotate more smoothly, reduces jamming, ensures accurate and efficient dispensing operations, and improves product quality.

[0014] Furthermore, a micro motor is provided on the fixed rod above the drive gear, and the output end of the micro motor passes through the fixed rod and is connected to the drive gear.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: a micro motor is set above the drive gear on the fixed rod, and its output end passes through the fixed rod and is connected to the drive gear. This has significant advantages. The micro motor is small in size but can accurately exert force and provide stable power to the drive gear. This structure is compact, saves space, achieves efficient transmission, can flexibly adjust the speed, accurately control the operation of the drive gear, meet the needs of different working scenarios, and improve the overall working efficiency of the equipment.

[0016] Furthermore, the dispensing assembly consists of a connecting sleeve fitted at the bottom of the dispensing tube, a rubber sleeve, and a dispensing head, with a limiting glue rod provided between the connecting sleeve and the dispensing head.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The dispensing assembly consists of a connecting sleeve, a rubber sleeve, and a dispensing head. A limiting rubber rod is provided between the connecting sleeve and the dispensing head, which has a significant effect. The connecting sleeve is firmly fitted onto the bottom of the dispensing tube, ensuring a tight connection without leakage. The rubber sleeve plays a buffering and protective role. When the dispensing head comes into contact with a hard object, the rubber sleeve bends, preventing the dispensing assembly from coming into contact with the human body and causing injury due to operational errors during use. Furthermore, the limiting rubber rod further assists in limiting the rubber sleeve, preventing the rubber sleeve from bending during use and causing dispensing errors.

[0018] Furthermore, a plurality of the limiting rubber rods are provided, and the plurality of limiting rubber rods are arranged in a ring, and the included angle between two adjacent limiting rubber rods is equal.

[0019] The beneficial effects of adopting the above-mentioned further solution are: multiple limiting glue rods are distributed in a ring and adjacent angles are equal, which brings many benefits. This layout can form uniform support and constraint between the connecting sleeve and the dispensing head, making the glue dispensing process more stable and avoiding glue dispensing deviation caused by uneven local force.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the drive assembly consists of inner and outer drive discs, with an ingenious layout and significant effect.
