Description

Technical Field

[0001] The utility model relates to a conveying device for wet processes, in particular to a dust-proof shaft seat structure of a conveying device for wet processes. Background Art

[0002] During the wet process of a board such as a circuit board, it is necessary to rely on a conveying unit to convey the board.

[0003] It is known that the conveying unit includes a plurality of conveying members, and each conveying member includes an upper rotating shaft, a lower rotating shaft, and a driving gear. The upper rotating shaft and the lower rotating shaft are arranged side by side up and down, and each is provided with a roller piece and an interlocking gear. The two interlocking gears mesh with each other, and the two roller pieces are arranged opposite to each other up and down; the upper rotating shaft or the lower rotating shaft is further provided with a driven gear, and the driving gear meshes with and drives the driven gear to rotate, so that the upper rotating shaft and the lower rotating shaft rotate relative to each other.

[0004] The upper rotating shaft and the lower rotating shaft respectively pass through the shaft holes of the upper shaft seat and the lower shaft seat, and are supported by the shaft holes of the upper shaft seat and the lower shaft seat. In this way, the upper rotating shaft rotates relative to the upper shaft seat under the support of the shaft hole, and the lower rotating shaft rotates relative to the lower shaft seat under the support of the shaft hole. As for the board, it is clamped between the two roller pieces, so that the board is driven by the two relatively rotating roller pieces.

[0005] However, since the shaft seats must support the rotating shafts with the inner edges of their shaft holes, the outer peripheral surfaces of the rotating shafts will rub against the inner edges of the shaft holes during rotation to generate powder (or dust), and the generated powder will also disperse everywhere, for example, disperse onto the board and the roller pieces. In this way, the powder is likely to adhere to the surface of the board, which will affect the yield of the product.

[0006] Therefore, how to improve the above-mentioned deficiencies of the prior art is a major issue that the inventors of this application are eager to solve. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a dust-proof shaft seat structure of a conveying device for wet processes, which can prevent the generated powder from dispersing everywhere.

[0008] To achieve the above object, the present application provides a dust-proof shaft seat structure for a wet process conveying device, which is used to support a rotating shaft. The dust-proof shaft seat structure includes: a first shaft seat; and a second shaft seat. Both the first shaft seat and the second shaft seat have a dust-falling opening and each includes a shaft seat body and a dust-proof cover; the shaft seat body is provided with a seat hole, and the rotating shaft passes through the seat hole and is supported by the inner edge of the seat hole; the dust-proof cover is combined with the shaft seat body and together forms a dust collection space between the shaft seat body and the dust-proof cover. The dust collection space communicates with the dust-falling opening. The dust-proof cover is provided with a cover hole, and the rotating shaft passes through the cover hole, and there is a gap between the inner edge of the cover hole and the outer edge of the rotating shaft; the first shaft seat and the second shaft seat are adjacent to each other, and the dust collection space and the dust-falling opening of the first shaft seat communicate with the dust collection space and the dust-falling opening of the second shaft seat.

[0009] Compared with the prior art, the present utility model has the following effects: it can prevent the powder and chips from the shaft seat body from spreading onto the plate parts and the roller sheets, thereby ensuring the product yield. In addition, even if the dust-proof cover is added, the amount of powder and chips will not increase. Brief Description of the Drawings

[0052] The detailed description and technical content of the present utility model are described below in conjunction with the accompanying drawings. However, the attached drawings are only for reference and description, and are not intended to limit the present utility model.

[0053] The present utility model provides a dust-proof shaft seat structure for a wet process conveying device, as Figure 3 shown, which is applied to a conveying device 900 to collect dust during the conveying process. As Figures 1 to 4 shown is the first embodiment, and as Figures 5 to 6 shown is the second embodiment.

[0054] As Figures 1 to 3 shown, it is the first embodiment of the dust-proof shaft seat structure (abbreviation: dust-proof shaft seat structure) 100a of the wet process conveying device of the present utility model. The dust-proof shaft seat structure 100a is used to support a rotating shaft (such as a first rotating shaft 91 and a second rotating shaft 92), and it includes: a first shaft seat 1 and a second shaft seat 2 that are adjacent to each other in the up and down directions.

[0055] The first shaft seat 1 has two ends that are opposite to each other in the up and down directions. One end is a closed end, and the other end is an open end; among them, the closed end can be a cover plate 123, but the present application does not limit this, and the open end is defined as a dust falling opening H1. The first shaft seat 1 includes a shaft seat body 11 and a dust-proof cover 12 that can be combined and fixed with each other. Among them, the combination and fixing method can be snap-fastening or bonding, but the present utility model does not limit this.

[0056] The shaft seat body 11 is provided with a seat hole 111 in the shape of a fish-eye hole, and the length direction of the seat hole 111 is parallel to the aforementioned up and down directions.

[0057] The dust-proof cover 12 is provided with a cover hole 1211 also in the shape of a fish-eye hole, and the length direction of the cover hole 1211 is also parallel to the aforementioned up and down directions.

[0058] The dust-proof cover 12 and the shaft seat body 11 are combined and fixed with each other, and a dust collection space S1 for concentrating powder debris is jointly formed between the dust-proof cover 12 and the shaft seat body 11. The dust collection space S1 is communicated with the aforementioned dust falling opening H1. In other words, the combined first shaft seat 1 is a closed covering shell. Except for the seat hole 111 and the cover hole 1211, this covering shell has only one opening: the dust falling opening H1. In addition, the cover hole 1211 and the seat hole 111 correspond to each other and are both communicated with the dust collection space S1; moreover, the seat hole 111 is located below the highest point of the dust collection space S1.

[0059] As Figure 3As shown, the conveying device 900 includes at least one conveying member (not labeled with an attached drawing reference numeral), and the conveying member includes a first rotating shaft 91, a second rotating shaft 92, and a driving gear G1. The first rotating shaft 91 and the second rotating shaft 92 are spaced side by side from each other in the aforementioned up and down direction and are each provided with a roller piece R and an interlocking gear G3. The two interlocking gears G3 are meshed with each other in the up and down direction, and the two roller pieces R are arranged opposite to each other in the up and down direction; the second rotating shaft 92 is further provided with a driven gear G2, and the aforementioned driving gear G1 meshes with and drives the driven gear G2 to rotate, causing the first rotating shaft 91 and the second rotating shaft 92 to rotate relative to each other.

[0060] The first rotating shaft 91 and the second rotating shaft 92 respectively pass through the first shaft seat 1 and the second shaft seat 2. Specifically, the first rotating shaft 91 passes through the seat hole 111 of the seat body 11 of the shaft seat and is also supported by the inner edge of the seat hole 111. In other words, the inner edge of the seat hole 111 will contact the outer peripheral surface of the first rotating shaft 91. Therefore, when the first rotating shaft 91 rotates, it will rub against the inner edge of the seat hole 111 to generate powder debris; the first rotating shaft 91 only passes through the cover hole 1211 of the dust-proof cover 12 but does not contact the inner edge of the cover hole 1211. Specifically, a gap D is fixedly maintained between the inner edge of the cover hole 1211 and the outer peripheral surface of the first rotating shaft 91 (as Figure 4 shown). In other words, only the seat hole 111 of the seat body 11 of the shaft seat will generate powder debris, and the cover hole 1211 of the dust-proof cover 12 will not generate powder debris. The gap D can be, for example, approximately 1.5 mm, but the present utility model does not limit this.

[0061] In this way, the powder debris from the seat hole 111 will be concentrated in the dust collection space S1, and then the gravitational force can be utilized to make these powder debris fall downward through the dust falling opening H1.

[0062] The second shaft seat 2 is substantially the same as the first shaft seat 1, with the differences being that: both ends of the second shaft seat 2 in the up and down direction are open ends, and these two open ends are respectively the dust falling through port H3 located above and the dust falling opening H2 located below; and, the seat hole 211 opened in the seat body 21 of the shaft seat and the cover hole 2211 opened in the dust-proof cover 22 are both circular holes corresponding to the second rotating shaft 92.

[0063] In the second shaft seat 2, the second rotating shaft 92 passes through the seat hole 211 of the seat body 21 of the shaft seat and is also supported by the inner edge of the seat hole 211, causing the inner edge of the seat hole 211 to contact the outer peripheral surface of the second rotating shaft 92. Therefore, when the second rotating shaft 92 rotates, it will also rub against the inner edge of the seat hole 211 to generate powder debris; the second rotating shaft 92 only passes through the cover hole 2211 of the dust-proof cover 22 but does not contact the inner edge of the cover hole 2211 because a gap D is also reserved between the inner edge of the cover hole 2211 and the outer peripheral surface of the second rotating shaft 92 (as Figure 4As shown, only the seat hole 211 of the seat body 21 will generate powder debris, and the cover hole 2211 of the dust cover 22 will not generate powder debris. The gap D can be, for example, about 1.5 mm, but the present utility model is not limited thereto.

[0064] Furthermore, the combined second shaft seat 2 is a wrap-around shell that penetrates up and down, and this wrap-around shell has only two openings, one above and one below: the dust-falling through port H3 located above and the dust-falling opening H2 located below.

[0065] After the dust cover 22 and the seat body 21 are combined and fixed to each other, a dust collection space S2 for concentrating powder debris will also be jointly formed between the dust cover 22 and the seat body 21. The dust collection space S2 is connected to the aforementioned dust-falling through port H3 and dust-falling opening H2 located above and below respectively. In other words, the combined second shaft seat 2 is a wrap-around shell that penetrates up and down as described above, and the seat hole 211 and the cover hole 2211 of this wrap-around shell both penetrate the second rotating shaft 92. In addition, the cover hole 2211 and the seat hole 211 correspond to each other and are both connected to the dust collection space S2; moreover, the seat hole 211 is located below the highest point of the dust collection space S2.

[0066] In this way, the powder debris from the seat hole 211 will be concentrated in the dust collection space S2, and then the universal gravitation can be used to make these powder debris fall downward through the dust-falling opening H2 (for example, it can fall to a powder debris collection center (not shown in the figure)).

[0067] As Figure 2 、 Figure 3 and Figure 4 shown, the first shaft seat 1 and the second shaft seat 2 are adjacent to each other in the up and down direction, so that the dust collection space S1 is connected to the dust collection space S2 through the dust-falling opening H1 and the dust-falling through port H3. In this way, the powder debris generated by the friction of the first rotating shaft 91 on the seat hole 111 will be concentrated in the dust collection space S1 (the powder debris will not scatter outside) and fall out through the dust collection space S2 and the dust-falling opening H2; as for the powder debris generated by the friction of the second rotating shaft 92 on the seat hole 211, it will be concentrated in the dust collection space S2 (the powder debris will not scatter outside) and fall out through the dust-falling opening H2.

[0068] Thereby, the powder debris from the two shaft seat bodies 11 and 21 can be concentrated in the dust collection spaces S1 and S2 of the first shaft seat 1 and the second shaft seat 2, so that the powder debris will not disperse everywhere outside the first shaft seat 1 and the second shaft seat 2. Therefore, it has the effect of preventing the powder debris from dispersing onto the plate member (not shown in the figure) and the roller piece R, thereby ensuring the product yield. Furthermore, the powder debris concentrated in the dust collection spaces S1 and S2 can also jointly fall into, for example, the powder debris collection center through the dust falling opening H2, so as to collect and discard the powder debris centrally, and thus has the effect of not polluting the environment. Thirdly, although the dust-proof covers 12 and 22 are added in the present utility model, since the inner edges of the cover holes 1211 and 2211 of the dust-proof covers 12 and 22 do not contact the first rotating shaft 91 and the second rotating shaft 92, the amount of powder debris in the present utility model will not increase due to the addition of the dust-proof covers 12 and 22.

[0069] As Figure 1 and Figure 3 shown, it should be noted that the shaft seat bodies 11 and 21 of the first embodiment are both plate-like bodies, and the dust-proof covers 12 and 22 of the first embodiment are both cover-shaped bodies having a recessed portion 125 and 225. The dust-proof covers 12 and 22 are correspondingly covered on the shaft seat bodies 11 and 21, so that the shaft seat bodies 11 and 21 can be correspondingly covered by the recessed portions 125 and 225 to form the aforementioned dust collection spaces S1 and S2.

[0070] Specifically, the dust-proof cover 12 of the first shaft seat 1 has a rear wall 121, two side walls 122 and a cover plate 123. The two side walls 122 are connected to two opposite side edges of the rear wall 121 side by side at intervals. The cover plate 123 is connected between one end (for example, the upper end) of the rear wall 121 and one end (for example, the upper end) of each side wall 122. The cover hole 1211 is opened on the rear wall 121, and the aforementioned recessed portion 125 is formed between the rear wall 121, the two side walls 122 and the cover plate 123. It should be noted that the cover plate 123 correspondingly closes one end of the first shaft seat 1 to form the aforementioned closed end. The dust-proof cover 22 of the second shaft seat 2 has a rear wall 221 and two side walls 222. The two side walls 222 are connected to two opposite side edges of the rear wall 221 side by side at intervals. The cover hole 2211 is opened on the rear wall 221, and the aforementioned recessed portion 225 is formed between the rear wall 221 and the two side walls 222.

[0071] As Figures 5 to 6 shown, it is the second embodiment of the dust-proof shaft seat structure 100b of the present utility model. The second embodiment is generally the same as the aforementioned first embodiment, except that: the structures of the shaft seat bodies 11 and 21 and the structures of the dust-proof covers 12 and 22 are swapped with each other. Therefore, the second embodiment also has all the effects of the first embodiment, which are described in detail as follows.

[0072] In the second embodiment, the shaft seat bodies 11 and 21 are both cover-shaped bodies with recessed portions 119 and 219, and the dust covers 12 and 22 are both plate-shaped bodies. The shaft seat bodies 11 and 21 are correspondingly covered by the dust covers 12 and 22, so that the dust covers 12 and 22 can correspondingly cover the recessed portions 119 and 219, and form the required dust collection spaces S1 and S2 between them after covering. Moreover, as Figure 6 shown, the first shaft seat 1 also has a dust falling opening H1, and the second shaft seat 2 also has a dust falling through hole H3 and a dust falling opening H2.

[0073] Among them, the shaft seat body 11 of the first shaft seat 1 has a rear wall 116, two side walls 117 and a cover plate 118. The two side walls 117 are connected to two opposite sides of the rear wall 116 at intervals side by side. The cover plate 118 is connected between one end (for example, the upper end) of the rear wall 116 and one end (for example, the upper end) of each side wall 117. The seat hole 111 in the shape of a fish-eye hole is opened on the rear wall 116 (the cover hole 1211 of the dust cover 12 is also in the shape of a fish-eye hole). As for the aforementioned recessed portion 119, it is formed between the rear wall 116, the two side walls 117 and the cover plate 118, and the cover plate 118 correspondingly closes one end of the first shaft seat 1 to form the required closed end. The shaft seat body 21 of the second shaft seat 2 has a rear wall 216 and two side walls 217. The two side walls 217 are connected to two opposite sides of the rear wall 216 at intervals side by side. The seat hole 211 in the shape of a circular hole is opened on the rear wall 216 (the cover hole 2211 of the dust cover 22 is also in the shape of a circular hole). As for the aforementioned recessed portion 219, it is formed between the rear wall 216 and the two side walls 217.

[0074] Moreover, the first rotating shaft 91 and the second rotating shaft 92 only contact the seat holes 111 and 211, and do not contact the cover holes 1211 and 2211.

[0075] To sum up, the dust-proof shaft seat structure of the wet process conveying equipment of the present invention can indeed achieve the expected use purposes and effects, and can solve the deficiencies of the prior art. Therefore, a patent application is filed.

[0076] The above are only the preferred embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structural changes made by using the content of the specification and drawings of the present invention shall be equally included in the scope of the rights of the present invention. It is hereby stated.
