Description

Technical Field

[0001] The invention relates to the technical field of glue dispensing for filter production and processing, and in particular to a precise glue dispensing device for filter production and processing. Background Art

[0002] A filter is a circuit device that allows signals within a certain frequency range to pass smoothly while suppressing or attenuating other frequency signals. Filter dispensing refers to the process of accurately applying glue to specific positions of the filter through dispensing equipment during the filter production process to achieve functions such as fixing, sealing or protection.

[0003] The invention with the existing authorization announcement number CN213792531U discloses a precise dispensing device for filter production and processing, including a workbench, a dispensing machine head is fixedly provided at one end in the middle position of the top of the workbench, a first support plate is fixedly provided at one end of the top of the workbench, a first slide groove is opened on one side of the first support plate, a slide bar is slidably provided in the first slide groove, a rack is fixedly provided at the top of the slide bar, a gear is meshed at the top of the rack, one end of the gear is interlaced and connected with one side of the first support plate, a hollow slide rail is fixedly provided at one end of the slide bar, a first slider is slidably provided at one end of the hollow slide rail, a connecting rod is fixedly provided at one end of the first slider, a fixed table is fixedly provided at the middle position of one end of the top of the workbench, a motor is fixedly provided at the top of the fixed table, and the output end of the motor is fixedly connected to one end of the connecting rod.

[0004] With the above technical solution, although the connecting rod is driven to rotate by the output end of the motor, the slider at one end of the connecting rod is slidably connected to the hollow slide rail, so that the rack fixed on one side of the hollow slide rail slides along the first slide groove, so that the gear meshing with the top of the rack drives the positioning ring on one side of the first support plate to rotate, which is convenient for flipping the filter, thereby facilitating the dispensing of glue on different sides of the filter. However, with the above technical solution, it is not convenient to preheat the surface of the filter before dispensing glue on the filter. The large temperature difference between the filter and the glue may cause uneven shrinkage of the glue layer and produce bubbles, and it is also easy to cause a decrease in the adhesion of the glue, thereby affecting the bonding effect, making it less practical. Therefore, a technician in this field provides a precise dispensing device for filter production and processing to solve the problems raised in the above background technology.
