Description

Technical Field

[0001] The utility model belongs to the technical field of production technology, and specifically relates to a PCB liquid collecting device and a PCB board production line. Background Art

[0002] PCB is an indispensable component in modern electronic devices. The main function of PCB is to realize signal transmission and power supply between electronic components. It provides a fixed and supported platform for electronic components. In PCB production, it is often necessary to go through steps such as copper coating, pattern electroplating, etching, drilling, gold plating, tin spraying, and mounting. Between these steps, PCB pattern transfer is often required. When the PCB board pattern is electroplated, the PCB board is generally immersed in chemical agents, and the circuit pattern and hole copper are thickened to customer requirements under the action of the electrolysis principle. After this step is completed and transferred to the etching process, a lot of chemical reagents will generally remain on the PCB board. This reagent is often highly corrosive. During transportation, whether it drips on the rack or the floor, it will damage the rack and the production environment, and the residual liquid will also contaminate other PCB boards, resulting in an increase in the defective rate of PCB boards.

[0003] In the prior art, although a structure for preventing leakage is provided, it is very inconvenient when cleaning. Especially when dumping chemical residual liquid, since some residual liquids are harmful to human body, it is very difficult to clean up.

[0004] And with the increase in production capacity, the racks for transferring PCB boards often have more than one layer, but multiple layers, which further increases the difficulty of cleaning the residues on each layer of the mechanism. Utility Model Content

[0005] In order to solve the above problems, the present application proposes a PCB moving device, which sets a liquid collecting component on the shelf. When the PCB is clamped on each shelf, the leaked liquid on the board will flow to the guide member due to the sharp angle of the shelf, and then flow to the liquid reservoir from the guide member. Thus, the rack body can automatically collect the residual liquid and discharge the residual liquid through the liquid reservoir. The device prevents the residual liquid from dripping on different levels and automatically collects the residual liquid into the liquid reservoir, reducing the difficulty of cleaning the rack.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] In a first aspect, the utility model provides a PCB liquid collecting device, comprising:

[0008] The main body of the rack;

[0009] At least one shelf is disposed on the frame body, and the angle between the lower surface of the shelf and the horizontal plane is an acute angle; and

[0010] The liquid collecting component comprises a flow guide and a liquid reservoir. The liquid reservoir is arranged at the bottom of the frame body. The upper end of the flow guide is connected to the shelf, and the lower end of the flow guide is connected to the liquid reservoir.

[0011] By setting the shelf and the horizontal plane at an acute angle, the shelf is tilted so that when the PCB board is placed on the shelf, the liquid attached to the PCB board flows from the highest point of the shelf to the bottom of the shelf; a flow guide is set at the bottom of the shelf so that when the liquid flows to the bottom of the shelf, it is guided by the flow guide to flow to the liquid reservoir. The device can effectively prevent the residual liquid from splashing when the PCB board is placed on the shelf due to residual liquid still attached to the PCB board, and then the residual liquid drops on other shelves to contaminate other PCB boards, thereby causing damage to other PCB boards. The device can also protect the rack from being corroded by the residual liquid, and use the liquid collection component to uniformly guide the liquid of each shelf to the bottom of the rack and discharge it uniformly, thereby reducing the difficulty of cleaning the device and reducing the uncontrollable risk of human body touching the residual liquid.

[0012] In some embodiments, the shelf includes a bottom plate and a side plate, the bottom plate is provided with a first card slot, and the side plate is provided with a second card slot corresponding to the first card slot; the first card slot and the second card slot are connected to the peripheral side of the PCB board.

[0013] Through the first card slot and the second card slot, when the PCB board is set on the shelf, the peripheral side is clamped inside the first card slot and the second card slot, so that the PCB board is not easy to move and stack, and the board surface is not easy to be scratched.

[0014] In some embodiments, the shelf is provided with a liquid collecting trough, which is located at the connection between the bottom plate and the side plate.

[0015] The liquid collecting tank is set at the connection between the bottom plate and the side plate. Since the shelf is set at an acute angle to the horizontal, the shelf is tilted, and the liquid collecting tank is set at the bottom of the tilt. Therefore, when the PCB board is connected to the shelf, the liquid will flow into the liquid collecting tank at the bottom due to the tilt, thereby collecting the liquid and further preventing the liquid from spilling.

[0016] In some embodiments, the upper end of the flow guide is connected to the liquid collecting tank.

[0017] The guide piece connects the liquid collecting tank and the liquid reservoir to transfer the waste liquid collected in the liquid collecting tank to the liquid reservoir, so that there is no accumulation of waste liquid in the shelf, reducing the difficulty of cleaning the waste liquid when cleaning the rack, and also achieving the effect of automatically collecting waste liquid.

[0018] In some embodiments, the rack body is provided with a limit bracket, the shelf is further provided with a limit plate, the limit plate is movably provided on the limit bracket, and a third slot is provided on the limit plate to be clamped on the upper end of the PCB board.

[0019] In order to further prevent overlapping and scratches between PCB boards caused by shaking of PCB boards when the PCB boards are transferred on the shelf, a third slot is provided on the circumferential side of the PCB board in addition to the first slot and the second slot. The third slot is provided on a limit plate, and the limit plate is movably provided on a limit bracket so that the limit plate can abut against or move away from the PCB board, thereby enabling the third slot to be connected to or detached from the PCB board. At the same time, the movable limit plate also enables the shelf to adapt to the connection of PCB boards of various specifications.

[0020] In some embodiments, sliding sleeves are sleeved on both sides of the limiting plate, the sliding sleeves move on the limiting bracket, and the sliding sleeves are provided with knobs, which are turned to position the sliding sleeves on the limiting bracket.

[0021] The limit plate is connected to the limit bracket through a sliding sleeve and moves. In order to enable the limit plate to limit the PCB board, a knob part is also provided, so that when the limit plate is limited on the PCB board, the movement of the limit plate is limited by the knob part.

[0022] In some embodiments, there are two shelves, which are arranged on the rack body in a vertical direction, and each shelf is connected to the liquid reservoir through different guide members.

[0023] Usually, two shelves can be provided, and guide members are provided through the two shelves, so that each shelf can guide the liquid into the liquid storage container.

[0024] In some embodiments, the liquid reservoir is provided with a valve, which is disposed at the bottom or the peripheral side of the liquid reservoir to discharge the liquid in the liquid reservoir.

[0025] The reservoir valve is used to discharge the liquid inside the reservoir and achieve the effect of removing waste liquid.

[0026] In some embodiments, the frame body includes a plurality of support frames and a base frame, wherein the base frame is connected and arranged at the bottom of the plurality of support frames; the liquid reservoir is arranged on the base frame; and a movable roller is also arranged at the lower end of the support frame.

[0027] The support frame and the base frame constitute the structure of the frame body. The liquid reservoir is arranged on the base frame so that the waste liquid can flow into the liquid reservoir. The moving wheels at the lower end of the support frame enable the entire frame body to move.

[0028] In a second aspect, the utility model provides a PCB board production line, which includes the above-mentioned PCB board liquid collecting device, and the PCB board turnover processing of the PCB board production line is realized through the PCB board liquid collecting device.

[0029] The PCB board liquid collecting device can prevent the defective rate of the entire production line from increasing due to liquid leakage when the PCB board is transferred, and can also prevent the leaked liquid from falling on the production line and corroding the production line or equipment.

[0030] The utility model provides a PCB liquid collecting device and a PCB board production line, which have the following effects:

[0031] By setting a liquid collecting component on the rack body, the liquid collecting component is set on each shelf, and a liquid reservoir is set under the rack body, and the waste liquid on each shelf is collected into the liquid reservoir through the guide piece and the inclined shelf setting. By using this rack, the residual liquid of the PCB board placed on the rack body can be collected into the liquid reservoir during transportation, thereby preventing the residual liquid on the PCB board from splashing or dripping during transportation, thereby corroding other circuit boards or the rack body. At the same time, the automatic collection of waste liquid can also reduce the difficulty of cleaning the rack body and reduce the risk of human body touching corrosive liquid.

[0047] Embodiment 1:

[0048] like Figure 1 As shown, this embodiment provides a PCB liquid collecting device, including:

[0049] The frame body 100;

[0050] At least one shelf 300 is disposed on the rack body 100, and the angle between the lower surface of the shelf 300 and the horizontal plane is an acute angle; and

[0051] The liquid collecting assembly 200 includes a flow guide 210 and a liquid reservoir 220 . The liquid reservoir 220 is disposed at the bottom of the rack body 100 . The upper end of the flow guide 210 is connected to the shelf 300 , and the lower end of the flow guide 210 is connected to the liquid reservoir 220 .

[0052] Specifically, in some embodiments, two shelves 300 are provided in the rack body 100, and a spacing of 655 to 665 mm is left between the shelves 300 to place PCB boards, and when the shelves 300 are set, an angle of 25° to 35° is set with the horizontal plane, so that when the PCB board is placed, the PCB board is also set at an angle of 25° to 35° with the horizontal plane.

[0053] Furthermore, the two shelves 300 are respectively provided with a liquid collecting assembly 200, and the guide member 210 is arranged in a tubular shape, one end of which is connected to the bottom of the inclined surface of the shelf 300, and the other end is connected to the liquid reservoir 220, so that when the waste liquid flows into the bottom of the shelf 300 through the inclination, the waste liquid is introduced into the liquid reservoir 220 through the guide member 210, thereby realizing the diversion and collection of each layer of waste liquid, and preventing the waste liquid from splashing during the movement or the waste liquid from dripping into other layers, causing damage to the PCB boards of other shelves 300.

[0054] The beneficial effect of the above embodiment is that the shelf 300 is arranged at an acute angle of 25° to 35° with the horizontal plane, so that the shelf 300 is arranged tilted, so that when the PCB board is arranged on the shelf 300, the liquid attached to the PCB board flows from the highest point of the shelf 300 to the bottom of the shelf 300; the guide member 210 is arranged at the bottom of the shelf 300, so that when the liquid flows to the bottom of the shelf 300, it is guided by the guide member 210 to flow to the liquid reservoir 220. The device can effectively prevent the residual liquid from splashing when the PCB board is placed on the shelf 300 due to the residual liquid still attached to the PCB board, and then the residual liquid drops on other shelves 300 to pollute other PCB boards, thereby causing damage to other PCB boards. The device can also protect the frame from being corroded by the residual liquid, and the liquid collecting component 200 can also guide the liquid of each shelf 300 to the bottom of the frame and discharge it uniformly, thereby reducing the cleaning difficulty of the device and reducing the uncontrollable risk of human body touching the residual liquid.

[0055] Embodiment 2:

[0056] Based on Example 1, Figure 2 to Figure 4 As shown, this embodiment further illustrates and optimizes the structure of a PCB liquid collecting device proposed in the embodiment.

[0057] In some embodiments, the shelf 300 includes a bottom plate 310 and a side plate 320 . The bottom plate 310 is provided with a first card slot 311 , and the side plate 320 is provided with a second card slot 321 corresponding to the first card slot 311 . The first card slot 311 and the second card slot 321 are connected to the peripheral side of the PCB board.

[0058] Specifically, the shelf 300 includes a bottom plate 310 and a side plate 320. A plurality of protrusions are provided on the bottom plate 310 and the side plate 320. A first card slot 311 is formed between the protrusions. The first card slot 311 of the bottom plate 310 and the side plate 320 clamps the two adjacent sides of the PCB board to prevent the circuit board from falling out of the shelf 300 during transportation.

[0059] Furthermore, since the shelf 300 is arranged at an angle, the bottom plate 310 is arranged as a stainless steel plate near the inclined bottom, so that the water droplets can slide down more quickly, making it easier to collect the water droplets.

[0060] Through the first card slot 311 and the second card slot 321, when the PCB board is set on the shelf 300, the peripheral side is clamped inside the first card slot 311 and the second card slot 321, so that the PCB board is not easy to move and stack, and the board surface is not easy to be scratched.

[0061] In some embodiments, the shelf 300 is provided with a liquid collecting tank 330 , and the liquid collecting tank 330 is located at the connection between the bottom plate 310 and the side plate 320 .

[0062] Specifically, a liquid collecting trough 330 is provided at the bottom of the inclined shelf 300, close to the position where the bottom plate 310 and the side plate 320 are connected. The liquid collecting trough 330 is a stainless steel plate so that waste liquid can slide more conveniently to the inclined bottom of the shelf 300. One side of the liquid collecting trough 330 is a first card slot 311, which is convenient for PCB board clamping.

[0063] The liquid collecting tank 330 is arranged at the connection between the bottom plate 310 and the side plate 320. Since the shelf 300 is arranged at an acute angle with the horizontal, the shelf 300 is inclined, and the liquid collecting tank 330 is arranged at the inclined bottom. Therefore, when the PCB board is connected to the shelf 300, the liquid will flow into the liquid collecting tank 330 at the bottom due to the inclination, thereby collecting the liquid and further preventing the liquid from spilling.

[0064] In some embodiments, the upper end of the guide member 210 is connected to the liquid collecting tank 330 .

[0065] Specifically, the guide member 210 is configured to be tubular, one end of the tube is connected to the liquid collecting tank 330, and is close to the connection between the bottom plate 310 and the side plate 320 of the shelf 300. The other end of the guide member 210 is connected to the liquid reservoir 220 to collect waste liquid.

[0066] Furthermore, in order to improve the efficiency of liquid collection, a smooth slope is provided at the connection between the inside of the liquid collecting tank 330 and the guide member 210 to improve the efficiency of liquid inflow and the efficiency of waste liquid collection.

[0067] The guide member 210 connects the liquid collecting tank 330 and the liquid reservoir 220 to transfer the waste liquid collected in the liquid collecting tank 330 to the liquid reservoir 220, so that there is no accumulation of waste liquid in the shelf 300, reducing the difficulty of cleaning the waste liquid when cleaning the rack, and also achieving the effect of automatically collecting waste liquid.

[0068] In some embodiments, the rack body 100 is provided with a limiting bracket 110, and the shelf 300 is also provided with a limiting plate 120. The limiting plate 120 is movably provided on the limiting bracket 110, and a third card slot 121 is provided on the limiting plate 120 to be clamped on the upper end of the PCB board.

[0069] Specifically, the limiting bracket 110 is obliquely arranged on both sides of the shelf 300, and the limiting plate 120 is slidably arranged on the limiting bracket 110, and the limiting plate 120 can move on the limiting bracket 110 toward the upper end of the PCB board clamped in the first clamping groove 311, and the limiting plate 120 is also provided with a third clamping groove 121, and the third clamping groove 121 can be formed by a roller, or between the limiting protrusions. The position of the third clamping groove 121 corresponds to the position of the first clamping groove 311 and the second clamping groove 321 when the PCB board is placed, so that when a PCB board is clamped, there is a set of corresponding first clamping groove 311, second clamping groove 321, and third clamping groove 121, and the three edges of the PCB board are clamped by the clamping grooves.

[0070] In order to further prevent overlapping and scratches between PCB boards caused by shaking of the PCB boards when the PCB boards are transferred on the shelf 300, a third slot 121 is provided on the circumferential side of the PCB board other than the first slot 311 and the second slot 321. The third slot 121 is provided on a limiting plate 120, and the limiting plate 120 is movably provided on the limiting bracket 110 so that the limiting plate 120 can abut against or move away from the PCB board, thereby enabling the third slot 121 to be connected to or detached from the PCB board. At the same time, the movable limiting plate 120 also enables the shelf 300 to adapt to the connection of PCB boards of various specifications.

[0071] In some embodiments, sliding sleeves are sleeved on both sides of the limiting plate 120 , the sliding sleeves move on the limiting bracket 110 , and the sliding sleeves are provided with knobs, which are turned to position the sliding sleeves on the limiting bracket 110 .

[0072] The limit plate 120 slides on the limit bracket 110 through a sliding sleeve, or is clamped on the limit bracket 110 through the clamping grooves provided on both sides of the limit plate 120; when sliding, in order to prevent the third clamping groove 121 from easily detaching from the PCB board during movement, a knob portion is also provided, and the knob portion is generally composed of a locking screw. When the PCB board is placed on the shelf 300 and clamped, after the position of the limit plate 120 on the limit bracket 110 is determined, the locking screw is tightened to clamp the limit plate 120, and then the limit plate 120 is clamped on the limit bracket 110.

[0073] The limit plate 120 is movably connected to the limit bracket 110 through a sliding sleeve. In order to enable the limit plate 120 to limit the PCB board, a knob part is also provided so that when the limit plate 120 is limited on the PCB board, the movement of the limit plate 120 is limited by the knob part.

[0074] In some embodiments, there are two shelves 300 , which are arranged on the rack body 100 along the vertical direction, and each shelf 300 is connected to the liquid storage tank 220 through different guide members 210 .

[0075] Usually, two shelves 300 may be provided, and the guide member 210 may be provided through the two shelves 300 so that each shelf 300 can guide the liquid into the liquid storage container 220 .

[0076] There are two shelves 300, each of which has a spacing of 655-665 mm for placing PCB boards, and the upper and lower shelves 300 are parallel and have an inclination angle, and the projection surfaces of the two shelves 300 in the horizontal direction are vertically arranged in the same direction.

[0077] In some embodiments, the liquid reservoir 220 is provided with a valve 221 , which is disposed at the bottom or the peripheral side of the liquid reservoir 220 to discharge the liquid from the liquid reservoir 220 .

[0078] Specifically, the liquid reservoir 220 is provided with a valve 221, and the valve 221 is arranged at the bottom of the liquid reservoir 220 to allow the liquid to be completely discharged. The valve 221 can be set as a pipeline port or a knob-type valve 221 port.

[0079] The valve 221 of the liquid reservoir 220 is used to discharge the liquid inside the liquid reservoir 220 and achieve the effect of removing waste liquid.

[0080] In some embodiments, the frame body 100 includes a plurality of support frames and a bottom frame, wherein the bottom frame is connected and arranged at the bottom of the plurality of support frames; the liquid reservoir 220 is arranged on the bottom frame; and a movable roller 140 is also arranged at the lower end of the support frame.

[0081] Specifically, the rack body 100 is vertically arranged on a base frame using four support frames, and the four support frames are connected by a cross bar. The cross bar can not only be used as a connecting rod to prevent the rack body 100 from falling apart, but also can be used as a handrail 130.

[0082] Furthermore, a U-shaped groove is provided on one side of the frame body 100, and the U-shaped groove can be used to hang production documents and prevent production information tables.

[0083] A liquid reservoir 220 is arranged on the base frame, and the liquid reservoir 220 is arranged as an annular square water pipe having the same shape as the base frame, and can collect waste liquid.

[0084] The support frame and the base frame constitute the structure of the frame body 100.
