Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a sponge stick automatic assembly device. Background Art

[0002] Disposable sponge sticks are also called sponge tooth sticks and oral cleaning sticks. They are a kind of medical supplies and are usually used for oral cleaning and disinfection. Figure 1 As shown, the sponge rod 10 is composed of a material rod 10.1 formed by plastic injection molding and a sponge 10.2, wherein the sponge is fixedly mounted on one end of the material rod.

[0003] The production process of sponge bars mainly includes several main working procedures such as bar injection molding, sponge cutting and molding, sponge and bar assembly and packaging. Among them, the sponge and bar assembly mainly adopts a bar insertion device to insert the bar into the corresponding sponge. For example, the utility model patent application with publication number CN110589465A discloses a bar insertion device for sponge bar production line processing. In the device, a bar arrangement mechanism crushes the bar material and clamps it into a rod feed belt to transport the bar material. The bar material is then clamped for the first time by a linear clamp mechanism. The linear clamp mechanism clamps the bar material and docks it with a swing clamp mechanism. By pushing the clamp changing mechanism, the bar material is pushed from the linear clamp mechanism to the swing clamp mechanism. The swing clamp mechanism performs a second clamping, and the horizontal bar material is adjusted to a vertical state by the swing of the swing clamp mechanism. Finally, the bar material is vertically inserted into the sponge. The above-mentioned rod insertion device, when grasping, uses a linear clamp mechanism and a swing clamp mechanism to grasp twice, and needs to change the clamp once in the middle. The structure and process are relatively complicated, and the connection of each link is required to be high. The design and debugging are time-consuming and labor-intensive, and the cost is high. In addition, the rod material needs to be coated with glue on one end before being inserted into the sponge so that it can be fixed with the sponge after insertion. The glue is a mixture of multiple compounds, some of which are highly volatile and irritating. Volatilization into the air will seriously affect the working environment. Working in this environment for a long time may cause discomfort in the nose, pharynx, and throat, and irritating symptoms such as burning sensation and coughing.

[0004] Therefore, there is an urgent need to provide a sponge bar assembly device with simple structure and process, convenient maintenance, and environmental protection and safety. Utility Model Content

At the same time, the silo indexing plate and sensor are used to identify the position of the bar groove on the rod feeding roller, ensuring that the bar can accurately enter the bar groove.

[0033] (6) The rod-moving mechanism can prevent the material rod from getting stuck when it falls to the rod-feeding slide, thus ensuring the continuity and stability of material feeding.

The arrow in the figure indicates that the rod material is placed downward in the V-shaped positioning groove 2.23 on the rod feeding slide plate 2.2.

[0066] In order to ensure the accurate position of the material rod 10.1, the size of the bar material embedding groove 2.31 is basically slightly larger than the outer diameter of the material rod 10.1. After the material rod 10.1 enters the bar material embedding groove 2.31, it will be squeezed by the arc surface.

As the rod-feeding roller 2.3 rotates, when the rod material in the rod material embedding groove 2.31 rotates to the rod-pushing portion 2.71, the rod material is ejected from the rod material embedding groove 2.31 under the pressure of the rod-pushing portion 2.71, so that it falls smoothly onto the rod-feeding slide plate 2.2.

[0073] In this embodiment, the linear transverse movement mechanism and each linear module are purchased products and belong to the existing technology, so their structure is not described in detail.

[0074] Working principle:

[0075] Place the material rod 10.1 in the material bin 2.1, and place the two sponge discs 11 on the sponge feeding mechanism 8 at the same time, start the equipment, and start the automatic assembly under the control of the control system 9.

[0076] The material rods 10.1 in the silo 2.1 fall into the material guide slot 2.6 in sequence, and then the first motor 2.8 drives the rod feeding roller 2.3 to rotate so that the bar material embedding groove 2.31 on it is aligned with the bottom of the material guide slot 2.6. The material rods 10.1 in the material guide slot 2.6 fall into the bar material embedding groove 2.31 under the action of gravity and the pressure of the upper material rods 10.1. Then, the first motor 2.8 drives the rod feeding roller 2.3 to rotate a certain angle again so that the next bar material embedding groove 2.31 is aligned with the bottom of the material guide slot 2.6, and the materials are fed one by one. The number of detection ports on the silo indexing plate 2.10 is the same as that of the bar material embedding groove 2.31, and the positions correspond. The silo indexing plate 2.10 and the rod feeding roller 2.3 rotate synchronously, and the position of the bar material embedding groove 2.31 is determined by identifying the position of the detection port on the silo indexing plate 2.10.

[0077] After the material rods 10.1 enter the material slot 2.31 one by one, they rotate together with the rod feeding roller 2.3 under the restriction of the arc surface. When the material rods 10.1 at the bottom of the rod feeding roller 2.3 are located above the rod feeding slide plate 2.2, the material rods 10.1 are pushed into the V-shaped positioning groove 2.23 by the rod pushing plate 2.7 of the rod pushing mechanism to realize the material feeding one by one. When the rod feeding slide plate 2.2 is full of materials, the control system 9 controls the first motor 2.8 to stop working, and the rod feeding linear module 2.13 drives the rod feeding slide plate 2.2 to move to the material rod turning mechanism 3.

[0078] At this time, the flip cylinder 3.1 drives the material rod socket 3.4 to rotate to the horizontal direction through the flip shaft 3.7 and the flip plate 3.8, and makes the socket face the material rod 10.1, and then the pneumatic slide 3.2 is started, and the material rod socket 3.4 is driven to move forward through the support seat 3.3, supporting one end of the material rod, and the other end of the material rod is against the material baffle plate 3.5, so that the material rod is inserted into the socket. At this time, the flip cylinder 3.1 rotates 90° to make the material rod in a vertical state. At the same time, the rod feeding linear module 2.13 drives the rod feeding slide plate 2.2 to reset to the starting position below the rod feeding roller 2.3, and loading is carried out again.

[0079] The vertical material rod is grasped by the clamping claw assembly 4.5 of the material rod grasping mechanism 4, and then, driven by the linear transverse movement mechanism 13, it moves to the top of the glue box 5.1, and the upper and lower modules 4.2 are driven by the third motor 4.15 to lower the upper and lower module mounting plates 4.1, so that the lower end of the material rod is dipped in glue; after dipping in glue, the third motor 4.15 drives the upper and lower modules 4.2 to lift the upper and lower module mounting plates 4.1, and then, driven by the linear transverse movement mechanism 13, it moves to the top of the sponge plate 11, and then descends again to insert the material rod into the hole on the sponge, completing one rod insertion.

[0080] Each time a sponge disc 11 is replaced, the pressing plate cylinder 7.12 of the sponge flattening mechanism 7 drives the pressing plate 7.11 to descend, and the sponge is gradually flattened. When flattening, the sponge feeding mechanism 8 drives the sponge fixing plate 8.3 to move and pass under the pressing plate 7.11.
