Description

Technical Field

[0001] This utility model relates to the field of glue coating equipment technology, specifically a vertical moving mechanism for a glue coating machine, which is applicable to the vertical lifting and lowering control structure of glue guns in multi-axis automatic glue coating equipment. Background Technology

[0002] Multi-axis glue applicators are widely used in high-precision automated glue application processes such as electronic packaging, automotive parts, and LED bonding. The vertical lifting of the glue gun is a key action for achieving precise dispensing and intermittent path spraying. Currently, traditional glue applicators often use a lead screw and stepper motor or a cylinder and slide rail drive for their Z-axis structure. The lead screw and stepper motor method suffers from low repeatability and limited starting acceleration, while the cylinder structure lacks flexible control and is difficult to meet the demands of complex processes.

[0003] Therefore, there is an urgent need to provide a vertical motion mechanism for dispensing adhesive that operates smoothly, positions accurately, and responds quickly, in order to improve the overall performance of dispensing equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a vertical moving mechanism for a glue applicator to solve the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical moving mechanism for a glue applicator, comprising: a connecting plate and a glue gun mounting plate; a servo motor is fixedly connected to the outer wall of the connecting plate, a helical gear is fixedly connected to one end of the drive shaft of the servo motor, a helical rack is fixedly connected to the outer wall of the glue gun mounting plate, one end of the helical gear meshes with the helical rack, and a stabilizing mechanism and a positioning mechanism are respectively provided between the connecting plate and the glue gun mounting plate; The stabilization mechanism includes a slider fixedly connected to the outer wall of the connecting plate and a slide rail fixedly connected to the glue gun mounting plate, with one end of the slider slidably connected to the slide rail; The positioning mechanism includes a reset sensor fixedly connected to one end of the connecting plate and a baffle fixedly connected to one end of the glue gun mounting plate, wherein the reset sensor is coupled to sense the baffle.

[0006] Preferably, two symmetrical rubber anti-collision blocks are fixedly connected to the outer wall of the glue gun mounting plate.

[0007] Preferably, the two rubber anti-collision blocks are located at the upper and lower ends of the glue gun mounting plate, respectively, and the rubber ends are both facing the connecting plate.

[0008] Preferably, a solenoid valve for controlling the glue gun is fixedly installed on the outer wall of the glue gun mounting plate on the side away from the rack, and a pipeline bracket is fixedly connected to its top.

[0009] Preferably, the outer wall of the connecting plate has multiple screw holes for fixing to the multi-axis glue applicator by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the servo motor replaces the traditional cylinder and stepper motor, and drives the helical gear and helical rack for transmission, which is fast and stable. The slide rail and slider stabilizer structure greatly reduces the vibration when the glue gun mounting plate moves on the connecting plate. They complement each other and are suitable for high-precision glue application. Secondly, during operation, the reset sensor on the connecting plate and the baffle on the glue gun mounting plate are used for non-contact sensing to locate the origin, which facilitates automatic return to the original position. At the same time, the rubber anti-collision block reduces mechanical impact damage. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a vertical moving mechanism for a glue applicator, comprising: a connecting plate 1 and a glue gun mounting plate 2; a servo motor 5 is fixedly connected to the outer wall of the connecting plate 1, a helical gear 6 is fixedly connected to one end of the drive shaft of the servo motor 5, a helical rack 7 is fixedly connected to the outer wall of the glue gun mounting plate 2, one end of the helical gear 6 and the helical rack 7 mesh with each other, and a stabilizing mechanism and a positioning mechanism are respectively provided between the connecting plate 1 and the glue gun mounting plate 2; The stabilization mechanism includes a slider 3 fixedly connected to the outer wall of the connecting plate 1, and a slide rail 4 fixedly connected to the glue gun mounting plate 2. One end of the slider 3 is slidably connected to the slide rail 4. The positioning mechanism includes a reset sensor 9 fixedly connected to one end of the connecting plate 1 and a baffle 10 fixedly connected to one end of the glue gun mounting plate 2. The reset sensor 9 is matched to the baffle 10. A servo motor 5 drives a helical gear 6, which meshes with a helical rack 7 to move the glue gun mounting plate 2 vertically. The slider 3 and slide rail 4 assist in improving the smoothness of movement and guiding accuracy. The reset sensor 9 and baffle 10 assist in the movement. The reset sensor 9 is a photoelectric sensor switch with its transmitter and receiver aligned. During reset, the baffle 10 is inserted between its transmitter and receiver to block the signal, thus triggering the switch to determine the initial or limit position and realize stroke control or zero calibration. The combination of these mechanisms improves the accuracy and stability of the glue application position, replacing traditional stepper motors and cylinders to achieve high-precision, high-response, and flexible control.

[0016] More preferably, the outer wall of the glue gun mounting plate 2 is fixedly connected with two mutually symmetrical rubber anti-collision blocks 8; During the up-and-down movement of the glue gun mounting plate 2, if the movement is too large or an accident occurs due to misoperation, the anti-collision block will act as a buffer to prevent hard collisions from damaging the equipment, improve equipment safety, and extend its service life.

[0017] More preferably, the two rubber anti-collision blocks 8 are located at the upper and lower ends of the glue gun mounting plate 2 respectively, and the rubber ends are both facing the connecting plate 1; Rubber anti-collision blocks 8 are installed at the upper and lower ends, with the rubber end facing the connecting plate 1. When approaching the limit position, the anti-collision block contacts the connecting plate 1 before the metal part, thus achieving buffering.

[0018] More preferably, a solenoid valve for controlling the glue gun is fixedly installed on the outer wall of the glue gun mounting plate 2 on the side away from the rack, and a pipeline bracket 11 is fixedly connected to its top. The glue gun mounting plate 2 integrates a solenoid valve to control the glue application switch, and an integrated pipeline rack 11 to manage the glue application pipeline, both of which assist in the installation and use of the glue gun.

[0019] More preferably, the outer wall of the connecting plate 1 has multiple screw holes for fixing to the multi-axis glue applicator by bolts; The connecting plate 1 is provided with multiple screw holes for integrated installation with a multi-axis glue applicator. Depending on the specific equipment structure, it is fixed to the glue applicator body by bolts to complete the positional adaptation and provide a Z-axis glue applicator path for the multi-axis glue applicator.

[0020] One specific application of this embodiment is as follows: the servo motor 5 drives the helical gear 6 to rotate, causing the glue gun mounting plate 2 to move to the origin. The fixed-point reset is completed by the insertion sensing of the reset sensor 9 and the baffle 10. Then, through the connected multi-axis glue applicator control system, the Z-axis position command is sent. The servo motor 5 controller rotates the helical gear 6 according to the input command. Through the cooperation with the helical rack 7, the glue gun of the glue gun mounting plate 2 moves smoothly up and down along the slide rail 4 to the set height. When the target position is reached, the solenoid valve opens to control the glue gun to spray glue. During the glue spraying process, it can cooperate with the X or Y axis of the multi-axis glue applicator to complete more path glue dispensing or trajectory glue application. If the program is abnormal or runs at the limit position, the rubber anti-collision block 8 provides a buffer for the connecting plate 1 to prevent hard collision.
