Description

Technical Field

[0001] The utility model relates to the field of absorbing moisture from the surface of a circuit board, in particular to a transport mechanism with a water absorbing function. Background Art

[0002] For example, patent No. 200820092890.3 is named as a water absorption device for electroplating workpieces. This device uses a sponge roller to solve the problem of carrying out the plating liquid and cleaning water on the electroplating production line, thereby preventing the liquid attached to the electroplated workpiece from being carried into the next tank.

[0003] It is not difficult to see that this water absorption device does not have the function of draining water. As we all know, after long-term use, the inside of the sponge is full of water and the water absorption performance decreases. Therefore, it is necessary to drain the sponge at a fixed point.

[0004] The previous drainage method was to use other mechanisms outside the device to drain water by squeezing the sponge. The problems with this drainage method are:

[0005] 1. The process of squeezing and draining the sponge regularly requires the entire electroplating equipment production line to stop production before it can be manually operated, which seriously affects production efficiency.

[0006] 2. Under the influence of gravity, the clean water accumulates in the lower half of the lower sponge roller. Since the lower sponge roller is in a relatively compact state in the tank body, the squeezing mechanism cannot enter under the lower sponge roller to squeeze out the water. Utility Model Content

[0007] In order to solve the above problems, the utility model provides a transport mechanism with a water absorption function. The mechanism for realizing the water absorption function is integrated into the transport mechanism in a split form, so that the production line can also squeeze and drain water during operation, and the production efficiency is significantly improved.

[0008] The utility model provides a transport mechanism with a water absorption function, and the second technical problem to be solved is to fully squeeze out the cleaning water in the lower half of the lower sponge roller.

[0009] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A transport mechanism with a water absorption function has at least two rows of transport wheels in its shell, characterized in that there are vacant areas between the transport wheels in each row, and the vacant areas in each row are opposite to each other, water-absorbing reels with water-absorbing materials are arranged in the vacant areas, and the water-absorbing reels in at least one row are fixed on a sliding mechanism in the shell, and the water-absorbing reels in another row are squeezed by the sliding mechanism, so that the water-absorbing reels in the other row are deformed and abut against adjacent supporting members.

[0011] Furthermore, the water absorbing material is a sponge coated on the water absorbing roller.

[0012] Furthermore, the support member is a water-retaining roller.

[0013] Furthermore, the sliding mechanism is a linearly movable slide groove and a pressure block movable in the slide groove provided on the inner side of the shell, and the shaft cores on both ends of the water suction reel are provided in the slide groove. The pressure block pushes the shaft core to cause extrusion between the water suction reels.

[0014] Furthermore, the water suction roller is made of plastic material.

[0015] Furthermore, it also includes a screw and a pressure plate. The sliding mechanism and the corresponding suction wheel of the sliding mechanism are provided with multiple pressure blocks, which are connected to the same pressure plate through screws. By pressing the lower pressure plate, multiple pressure blocks simultaneously apply pressure to the shaft core.

[0016] Furthermore, the transport wheel may be formed by a plurality of guide wheels distributed in an array at intervals.

[0017] Beneficial effects of the utility model:

[0018] 1. The water absorption method composed of the sliding mechanism and the support member in the utility model is independent of the operation of the transport wheel. The sliding mechanism and the support member cooperate to realize the squeezing between the water absorption rollers, which will not interfere with the normal operation of the transport wheel. Therefore, there is no need to stop the machine for drainage, which improves the preparation efficiency of the entire electroplating production.

[0019] 2. The support member in this drainage method serves the purpose of preventing the water-absorbing reel from further advancing. One water-absorbing reel applies pressure to the other water-absorbing reel through a sliding mechanism, and the other water-absorbing reel deforms and counteracts the support member, so that the water-absorbing material on the other water-absorbing reel is fully squeezed, and the cleaning water is discharged from the water-absorbing material. Therefore, the water-absorbing performance of the water-absorbing material can be stably exerted in subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-5 shown.

[0026] Figure 1 In this embodiment, the workpiece is a circuit board, X is the direction of entry of the circuit board, and the utility model is a transport mechanism with a water absorption function, comprising a shell, and openings are provided on both sides of the shell for the circuit board to enter and exit.

[0027] Inside the shell 1, there is a transport part for transporting the circuit board, accompanied by a water absorption link, the transport part includes transport wheels 6 distributed at the upper and lower parts, the workpiece is located between the upper and lower transport wheels 6, and moves in the direction X under the action of the upper and lower transport wheels 6; wherein, the arrangement of the upper and lower transport wheels 6 has at least one or more areas formed due to excessive spacing, in which a water absorption roller with a water absorption material on the surface is provided, and the water absorption roller is also distributed at the upper and lower parts, and when the workpiece passes through the water absorption roller, the moisture on its upper and lower surfaces will be absorbed by the water absorption material on the water absorption roller 2.

[0028] The utility model realizes drainage by means of a squeezing device for squeezing the upper and lower water suction wheels 21 against each other.

[0029] The squeezing device includes two parts, namely, an active drive and a passive support. The active drive is provided on the inner side of the housing 1 with a longitudinal chute 3 and a pressing block 4 that can move up and down in the chute 3. The shaft cores 22a at both ends of the upper water-absorbing reel 22 are located in the chute 3, and the pressing block 4 is located above the chute 3. When drainage is required, the pressing block 4 presses the shaft core 22a, so that the water-absorbing material of the upper water-absorbing reel 22 and the water-absorbing material of the lower water-absorbing reel 21 are squeezed against each other, and the cleaning water in the upper water-absorbing reel 22 is fully squeezed out. The cleaning water in the upper part of the lower water-absorbing reel 21 is also fully squeezed out under this squeezing.

[0030] The passive support part is the water retaining wheel 5 arranged below the lower water suction wheel 21. The water retaining wheel 5 has a supporting effect. When the lower water suction wheel 21 is squeezed by the upper water suction wheel 22, it will be deformed to a certain extent. The direction of this deformation is toward the water retaining wheel 5. When the lower water suction wheel 21 contacts and squeezes the water retaining wheel 5, the cleaning water in the lower half of the lower water suction wheel 21 is fully squeezed out.

[0031] It is not difficult to see that the water absorption mechanism provided by the utility model can fully squeeze out the water absorption material of the upper and lower water absorption rollers, thereby solving the problem of poor water absorption performance of the lower water absorption roller 2. In addition, this water absorption mechanism is integrated in the transportation part of the transportation circuit board and does not need to be used in conjunction with other mechanisms. Compared with the entire complete electroplating equipment, the advantages brought by integration enable the structure of the electroplating equipment to be optimized.

[0032] The water absorbing material in this embodiment is a sponge.

[0033] In this embodiment, three upper water-absorbing reels 22 and three lower water-absorbing reels 21 are provided, and the three pressing blocks 4 are connected to the same pressing plate 7 through screws 8. By pressing the pressing plate 7, the three pressing blocks 4 apply pressure to the shaft core 22a at the same time.

[0034] The transport wheel 6 can be composed of a plurality of guide wheels 61 distributed in an array at intervals. This is to make the transport part have a hydrophobic effect. A large amount of cleaning water flows away from the circuit board through the space between the spaces before entering between the water-absorbing rollers 2. This can slow down the filling time of the water-absorbing material.

[0035] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
