Dispensing equipment

Abstract

The utility model relates to the technical field of casing sealing, in particular to dispensing equipment. Comprising a rotating motor, a connecting rod, a glue spraying device and a hoisting plate, one end of the rotating motor is fixedly connected with the hoisting plate; the other end of the rotating motor is in transmission connection with the connecting rod to drive the connecting rod to rotate; the connecting rod extends from the rotating motor to the direction far away from the rotating motor; and the glue spraying device is connected with the connecting rod. In the prior art, due to the limitation of the structure of dispensing equipment, a nozzle can only move along a straight line, and the movement dimension of the nozzle is relatively limited. Therefore, when the nozzle and the product are positioned, the nozzle and the product need to be adjusted at the same time, and positioning between the nozzle and the product is relatively difficult. Compared with the prior art, the glue spraying device disclosed by the utility model can perform 360-degree unlimited rotation. Therefore, the overall motion dimension of the device is effectively increased, and positioning between the device and a product is greatly facilitated.

Description

Technical Field

[0001] This utility model relates to the field of casing and sealing technology, and in particular to an adhesive dispensing device. Background Technology

[0002] Dispensing equipment is an automated device used to precisely control the application of fluids. Its core components include a controller, pump and valve system, nozzles, and a motion platform. By programming the amount of adhesive, the path, and the speed, it achieves high-precision dot, line, and surface coating, adapting to materials of different viscosities. Technology types include time-pressure valves, screw valves, and jet dispensing, offering advantages such as improved production efficiency, reduced material waste, and ensured process consistency. Therefore, dispensing equipment is widely used in electronics manufacturing. The adhesive sprayed from nozzles fills and seals the gaps between the casings and components of electronic products.

[0003] In practical applications, to ensure the adhesive sprayed from the nozzle is effectively coated within a designated area, the relative position between the nozzle and the product needs to be pre-defined. However, due to the structural design of the dispensing equipment, the nozzle can only move linearly. Therefore, the nozzle's movement dimension is relatively limited. This means that positioning requires adjusting both the product's position and the dispensing equipment, indicating that the adjustment entities are not uniform. This further necessitates the conversion of adjustment parameters between different entities to achieve compatibility, resulting in relatively low positioning efficiency. Utility Model Content

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] A dispensing device includes: a rotary motor 1, a connecting rod 2, a spraying device 3, a lifting plate 4, a transmission structure 5, a translation structure 6, and a rotation structure 7. The lifting plate 4 has bolt through holes for assembly. The lifting plate 4 is fixedly connected to other structures by bolts, thereby lifting the entire device. The transmission structure 5 includes a driving gear 51, a driven gear 52, a rotating rod 53, and a connecting plate 54. One end of the rotating rod 53 is rotatably connected to the lifting plate 4. The other end of the rotating rod 53 is fixedly connected to the driven gear 52. Thus, the driven gear 52 is rotatably connected to the lifting plate 4. The connecting plate 54 is fixedly connected to the driven gear 52. The connecting plate 54 is fixedly connected to the connecting rod 2. The driving gear 51 is connected to the output end of the rotary motor 1. The driving gear 51 meshes with the driven gear 52. Simultaneously, one end of the rotary motor 1 is fixedly connected to the lifting plate 4. The connecting rod 2 extends from the rotary motor 1 in a direction away from the rotary motor 1.

[0020] The translation structure 6 includes a slider 61, a translation gear 62, and a translation motor 63. The output end of the translation motor 63 is connected to the translation gear 62. The slider 61 is connected to the glue spraying device 3. A cavity for accommodating the translation gear 62 is formed inside the slider 61. A sliding protrusion is also provided on the slider 61. A sliding groove is formed on the connecting rod 2. The sliding protrusion is respectively clamped on the upper and lower sides of the connecting rod 2 and embedded in the sliding groove. Furthermore, the connecting rod 2 is provided with teeth corresponding to the translation gear 62. The teeth extend from one end of the connecting rod 2 to the other end. The connecting rod 2 meshes with the translation gear 62 through the teeth.

[0021] The rotating structure 7 includes a rotating shaft 71 and a locking structure 72. One end of the rotating shaft 71 is rotatably connected to the slider 61, and the other end is connected to the glue spraying device 3. The locking structures 72 are respectively disposed on both sides of the rotating shaft 71. The locking structures 72 clamp the rotating shaft 71. Specifically, the locking structure 72 includes a locking plate 721, a transmission plate 722, a pressing plate 723, and a trigger plate 724. The locking plate 721 is in contact with the rotating shaft 71. The transmission plate 722 is connected to the locking plate 721. At the same time, the transmission plate 722 is slidably embedded in the slider 61. A sleeve cylinder is also fixedly provided at the end of the transmission plate 722 away from the locking plate 721. One end of the trigger plate 724 has a sleeve groove, and the trigger plate 724 is sleeved on the cylinder of the transmission plate 722 through the sleeve groove. At the same time, the trigger plate 724 is oscillatingly connected to the slider 61. A torsion spring is provided at the connection between the trigger plate 724 and the slider 61. On the other hand, the end of the trigger plate 724 away from the transmission plate 722 is connected to the pressing plate 723. The pressing plate 723 is arc-shaped. The slider 61 has a groove corresponding to the pressing plate 723.

[0022] In practical applications, if the position of the glue spraying device 3 needs to be adjusted, the rotary motor 1 is started. Driven by the rotary motor 1, the drive gear 51 rotates continuously, which in turn drives the driven gear 52 to rotate continuously. Driven by the driven gear 52, the connecting plate 54 drives the connecting rod 2 to rotate accordingly. Thus, through the connecting rod 2, the glue spraying device 3 rotates around the connecting plate 54, thereby adjusting the position of the glue spraying device 3. On the other hand, the diameter of the drive gear 51 is smaller than the diameter of the driven gear 52. Through the cooperation of the drive gear 51 and the driven gear 52, the rotation speed of the connecting plate 54 is adjusted to a suitable range, thereby making the rotation process more stable.

[0023] Simultaneously, the translation motor 63 can also be activated. Driven by the translation motor 63, the translation gear 62 rotates continuously, thereby pushing the slider 61 to slide along the connecting rod 2 in cooperation with the connecting rod 2, which in turn drives the glue spraying device 3 to slide along the connecting rod 2. Thus, the position of the glue spraying device 3 can be further adjusted.

[0024] Alternatively, the pressing plate 723 can be pressed, causing the pressing plate 723 to drive the trigger plate 724 to swing relative to the slider 61. Consequently, under the pull of the trigger plate 724, the transmission plate 722 will slide relative to the slider 61, thereby causing the locking plate 721 to move away from the rotating shaft 71. Simultaneously, during the swinging process of the trigger plate 724, it compresses the torsion spring between the trigger plate 724 and the slider 61, thus accumulating elastic force. At this point, the glue spraying device 3 can be rotated, causing it to rotate relative to the slider 61 about the rotating shaft 71, thereby further adjusting the position of the glue spraying device 3. After adjustment, the pressing plate 723 is released, releasing the accumulated elastic force of the torsion spring, causing the trigger plate 724 to swing in the opposite direction, thus causing the locking plate 721 to re-engage with the rotating shaft 71. At this point, the locking plate 721 locks the rotating shaft 71 through friction with it. It is worth noting that when the locking plate 721 is in contact with the rotating shaft 71, the torsion spring still maintains a certain elastic force output to enhance the pressure of the locking plate 721 on the rotating shaft 71, thereby enhancing the friction between the two, so that the two locking plates 721 can stably lock the rotating shaft 71. As a result, the position of the glue spraying device 3 can be further adjusted.

[0025] In summary, this invention can adjust the position of the glue spraying device 3 in three different dimensions. This effectively increases the number of movement dimensions of the glue spraying device 3, so that when positioning the relative position between the glue spraying device 3 and the product, only the position of the glue spraying device 3 needs to be adjusted, thereby improving positioning efficiency to a certain extent.
