Description

Technical Field

[0001] The invention relates to the technical field of plate surface treatment, and in particular to a liquid medicine soaking device. Background Art

[0002] The existing fixture adopts a turntable lever push structure. The plate is transported to the turntable lever, and the lower surface of the plate contacts the lever. The bottom end of the plate will rotate with the turntable, and the plate will slide down to the bottom of the medicine tank. The turntable keeps rotating, and the lever pushes the plate, causing the bottom end of the plate to rub against the medicine tank continuously. The friction produces a large number of fine particles and roughens the medicine tank. The rough surface easily causes the medicine to crystallize, and the fine particles are also easy to crystallize. The fine particles and crystals are easy to stick to the surface of the plate and get stuck in the holes of the plate, resulting in poor quality of the edge parts. The fine particles and crystals enter the filter, which is more likely to clog the filter, making the maintenance of the filter more frequent and increasing labor costs. Summary of the Invention

[0003] The main purpose of the present invention is to provide a chemical solution immersion device, which aims to design a fixture to enable the surface treatment of the plate and the immersion tank in a non-contact manner, thereby avoiding the roughening of the immersion tank caused by the friction between the plate and the chemical solution tank.

[0004] To achieve the above-mentioned purpose, the medicine immersion device proposed in the present invention includes: a immersion pool, a transmission device and a clamp device, the immersion pool has an inlet end and an outlet end, and the direction from the inlet end to the outlet end is the transmission direction; the transmission device is arranged above the immersion pool; the clamp device is arranged on the transmission device, and the height of the clamp device is less than the distance from the transmission device to the bottom of the immersion pool, and in the immersion pool, the transmission device transmits the clamp device toward the transmission direction; the clamp device includes a cross bar and a support rod, the cross bar is arranged on the transmission device, one end of the support rod is connected to the cross bar, and the other end is provided with a limiting structure for limiting the plate.

[0005] Optionally, there are at least two clamping devices, which are arranged in parallel along the conveying direction.

[0006] Optionally, the support rod has a first side and a second side that are opposite to each other, the first side is convexly provided with a first limiting portion, and the second side is convexly provided with a second limiting portion; the first limiting portion and the second limiting portion are arranged at the same height position of the support rod, and the first limiting portion and the second limiting portion are staggered in the conveying direction.

[0007] Optionally, the cross section of the support rod includes a long section and a short section, the long section and the short section are in a cross shape, one side of the long section is the first side, and the other side of the long section is the second side.

[0008] Optionally, the side edges of the support rods are provided with rounded corners.

[0009] Optionally, the clamp device further includes a limiting rod arranged in parallel with the support rod, the limiting rod is fixed to the cross rod, and the limiting rod is arranged close to the end of the cross rod.

[0010] Optionally, the limiting structure is a hook-type structure, which includes a side, a bottom plate and a hook body; the side, the bottom plate and the hook body are surrounded to form a V-shaped groove with an opening facing upward; there are multiple support rods, which are arranged in parallel and at intervals, and the hook body is arranged between adjacent support rods.

[0013] The technical solution of the present invention uses a clamping device to clamp the plate, allowing the plate to be surface treated in a non-contact manner between the plate and the immersion tank. This avoids friction between the plate and the bottom wall of the immersion tank. If the plate and the bottom wall of the immersion tank rub against each other, the surface of the bottom wall of the medicine tank will become rough. The rough bottom wall surface will cause the medicine and fine particles to crystallize. The crystals and fine particles are easily attached to the surface of the plate and then blocked in the holes of the plate, resulting in unstable quality of the plate. Specifically, the clamping device in the medicine immersion device is set on the transmission device, and the height of the clamping device is lower than the distance from the transmission device to the bottom of the immersion tank. The plate is fixed in place by the limiting structure of the clamping device, so that the plate can be immersed and moved without contact and friction with the bottom wall of the immersion tank. This avoids the roughness of the bottom wall of the immersion tank caused by friction between the plate and the immersion tank, reduces the probability of crystallization of crystals and fine particles, and improves the yield rate of the plate.

[0032] The present invention provides a liquid medicine soaking device for surface treatment of plates.

[0033] Reference Figures 1 to 10 In one embodiment of the present invention, the medicine immersion device includes: an immersion pool 1, a transmission device 2 and a clamp device 3. The immersion pool 1 has an inlet end 11 and an outlet end 12, and the direction from the inlet end 11 to the outlet end 12 is the transmission direction; the transmission device 2 is arranged above the immersion pool 1; the clamp device 3 is arranged on the transmission device 2, and the height of the clamp device 3 is less than the distance from the transmission device 2 to the bottom of the trough of the immersion pool 1. In the immersion pool 1, the transmission device 2 transmits the clamp device 3 in the transmission direction; the clamp device 3 includes a cross bar 31 and a support rod 32. The cross bar 31 is arranged on the transmission device 2, and one end of the support rod 32 is connected to the cross bar 31, and the other end is provided with a limiting structure 34 for limiting the plate. It should be noted that, in this embodiment, the plate is a PCB plate.

[0034] The technical solution of the present invention utilizes a clamping device 3 to clamp the plate, allowing the plate to be surface treated in a non-contact manner between the plate and the immersion tank 1. This avoids friction between the plate and the bottom wall of the immersion tank 1. If friction occurs, the surface of the bottom wall of the immersion tank 1 will become rough. This rough bottom wall surface can cause the medicated solution and fine particles to crystallize. Crystals and fine particles easily adhere to the surface of the plate and become trapped in the pores of the plate, resulting in unstable plate quality. Specifically, the clamping device 3 in the immersion device is mounted on the transmission device 2, and the height of the clamping device 3 is lower than the distance from the transmission device 2 to the bottom of the immersion tank 1. The plate is fixed in place by a retaining structure 34 of the clamping device 3, allowing the plate to be immersed and moved without contact or friction with the bottom wall of the immersion tank 1. This avoids the roughening of the bottom wall of the immersion tank 1 caused by friction between the plate and the immersion tank 1, reduces the probability of crystallization of crystals and fine particles, and improves the yield rate of the plate.

[0035] Furthermore, at least two clamping devices 3 are provided and arranged in parallel along the conveying direction. It should be noted that in this embodiment, the clamping devices 3 can clamp the plate, so that the plate can continue to move in the conveying direction, and can also move the plate while being limited by the front and rear clamping devices 3, thereby avoiding friction between the plate and the bottom wall of the immersion tank 1.

[0036] Further, refer to Figure 7 The support rod 32 has a first side 321 and a second side 322 that are separated from each other. The first side 321 is provided with a first limiting portion 323, and the second side 322 is provided with a second limiting portion 324. The first limiting portion 323 and the second limiting portion 324 are provided at the same height of the support rod 32, and the first limiting portion 323 and the second limiting portion 324 are staggered in the conveying direction. It should be noted that in this embodiment, for two adjacent clamping devices 3, the second limiting portion 324 of the front clamping device 3 and the first limiting portion 323 of the rear clamping device 3 are staggered in position, that is, the second limiting portion 324 of the front clamping device 3 can cooperate with the first limiting portion 323 of the rear clamping device to form a limiting structure 34. The limiting structure 34 formed by the cooperation of the first limiting portion 323 and the second limiting portion 324 can prevent the plate from falling from the upper position of the clamp. Moreover, the cooperation between the first limiting portion 323 and the second limiting portion 324 can also fix the positions of the front and rear clamp devices 3 and there is no gap between the front and rear clamp devices 3 , which improves the stability of the clamp device 3 and prevents the clamp device 3 from shaking violently.

[0037] It should be noted that in this embodiment, a vibration motor is provided near the transmission member 21 of the transmission device 2. The function of the vibration motor is to vibrate the transmission member 21. The vibration of the transmission member 21 drives the clamp device 3 to vibrate, thereby allowing the liquid medicine to fully enter the micropores of the plate inside the clamp device 3. The clamp devices 3 located at the front and rear positions can maintain structural stability while vibrating through the restraining cooperation of the first limiting portion 323 and the second limiting portion 324. If the first limiting portion 323 and the second limiting portion 324 are not provided, the vibration of the vibration motor may cause the clamp device 3 located at the front to collide with the clamp device 3 located at the rear, ultimately resulting in collision and friction between the clamp devices 3, the plate and the clamp device 3, or the plate and the plate, thereby causing damage to the plate and reducing the yield rate of the plate.

[0038] Further, refer to Figure 7 The cross-sectional position of the middle support rod 32 is shown. The cross-sectional position of the support rod 32 includes a long section and a short section. The long section and the short section are in a cross-shaped configuration. One side of the long section is the first side 321, and the other side of the long section is the second side 322. It should be noted that in this embodiment, the cross-sectional shape of the support rod 32 is a cross-shaped configuration. The cross-shaped support rod 32 can withstand forces parallel to the direction in which the long section extends and forces in the direction in which the short section extends, thereby providing the support rod 32 with higher structural strength and preventing the support rod 32 from breaking during the movement of the clamp device 3.

[0039] Furthermore, to prevent the support rod 32 from scratching the plate, the side edges of the support rod 32 are provided with rounded corners. The rounded corners can effectively prevent the plate from abutting and scratching the plate due to the plate's jumping during transmission, thereby affecting the quality of the plate.

[0040] Furthermore, the clamp device 3 also includes a limiting rod 33 arranged in parallel with the support rod 32. The limiting rod 33 is fixed to the cross bar 31 and is arranged near the end of the cross bar 31. The limiting rod 33 fixed on the cross bar 31 is used to limit the horizontal direction of the plate to prevent the plate from escaping from the clamp device 3. Specifically, the limiting rod 33 is provided with a third limiting portion 331 on the side facing the transmission direction. The protrusion of the third limiting portion 331 can effectively block the movement of the plate, thereby keeping the relative position of the plate and the clamp device 3 fixed, so as to facilitate the surface treatment of the plate in the immersion tank 1 and prevent the plate from falling from the clamp device 3 into the immersion tank 1 and affecting the normal plate processing process.

[0041] Furthermore, the limiting structure 34 is a hook-shaped structure, referring to Figure 2 and Figure 4 The hook-shaped structure includes a side portion 341, a bottom plate 342 and a hook body 343; the side portion 341, the bottom plate 342 and the hook body 343 enclose a V-shaped groove 344 with an opening facing upward. The V-shaped groove 344 with an opening facing upward facilitates the plate to enter the V-shaped groove 344. Specifically, the distance between the side portion 341 and the hook body 343 gradually decreases downward in the height direction. When the clamp device 3 is rotated into the soaking pool 1 by the transmission device 2, the plate can slide down along the support rod 32, and then finally fall into the bottom position of the V-shaped groove 344, that is, on the bottom plate 342, through the guidance of the side portion 341 and the hook body 343. The limiting rods 33 arranged on both sides of the support rod 32 of the clamp device 3 can limit the plate in the left and right directions to prevent the plate from escaping from the clamp device 3 from the side position. The support rods 32 are provided in plurality and arranged in parallel and at intervals, and the hooks 343 are provided between adjacent support rods 32. In one embodiment, when the front clamp device 3 cooperates with the rear clamp device 3, the hooks 343 of the rear clamp device 3 can be embedded between adjacent support rods 32 of the front clamp device 3. The front clamp device 3 cooperates with the rear clamp device 3 so that there is no gap between the front and rear clamp devices 3.

[0042] It should be noted that in this embodiment, the edges of the clamp device 3 are all provided with rounded corners. Specifically, the edges of the support rod 32 are provided with rounded corners, and the edges of the side portion 341, bottom plate 342, and hook body 343 of the hook structure are all provided with rounded corners. The benefit of the rounded corners is that the clamp device 3 is smooth as a whole, without sharp parts that could cause scratches between the panel itself and the clamp device 3, thus preventing damage to the clamp device 3 or the panel.

[0043] Furthermore, the cross-sectional area of ​​the support rod 32 is gradually reduced from one end of the cross bar 31 to the direction close to the limiting structure 34. In other words, the cross-sectional area of ​​the support rod 32 is larger on the side closer to the cross bar 31, and smaller on the side farther away from the cross bar 31. The closer the support rod 32 is to the cross bar 31, the greater its ability to withstand force, and the support rod 32 can withstand the vibration caused by the greater force. The farther the support rod 32 is from the cross bar 31, the smaller its ability to withstand force, but the greater its swing amplitude, so this side of the support rod 32 is more likely to shake and vibrate, thereby allowing the bubbles in the micropores of the plate to detach and facilitating the entry of the medicine into the micropores of the plate.

[0044] Furthermore, the crossbar 31 is further provided with a connecting member 311 and a slider 312. The transmission device 2 is provided with a transmission member 21 and a guide slot 22. The connecting member 311 is fixedly connected to the transmission member 21, and the slider 312 is movably disposed in the guide slot 22. Specifically, the connecting member 311 is a chain, and the clamping device 3 is driven by a motor and a chain transmission, enabling the clamping device 3 to cyclically enter and exit the immersion tank 1. Since the clamping device 3 itself has a certain weight, and the clamping device 3 is arranged on the chain, the chain itself will undergo a certain deformation due to the gravity of the clamping device 3. The slider 312 is provided on the crossbar 31 and is disposed in the guide slot 22. In this way, the slider 312 can provide a certain support while moving along the guide slot 22, thereby preventing the chain from collapsing or breaking due to excessive force.

[0045] Furthermore, the clamping device 3 is made of plastic. Using plastic reduces the overall weight of the clamping device 3, allowing the transmission device 2 to reduce the amount of work required to overcome the gravity of the clamping device 3 during transmission and transportation. This improves the utilization rate of the transmission device 2's motor, increases energy utilization, and effectively conserves energy consumed during the transmission process. However, this design is not limited to this. In other embodiments, the clamping device 3 may also be made of metal or other non-metallic materials.
