Description

Technical Field

[0001] The utility model relates to the technical field of PCB board preparation equipment, in particular to a PCB board static device. Background Art

[0002] In the prior art PCB production process, it is often necessary to let the PCB stand still. For example, CN109413882A discloses a PCB solder mask manufacturing process for LED display screens, which includes the following steps: (1) pre-treatment: using a browning process to treat the surface of the PCB; (2) screen printing: screen printing the copper surface of the PCB, strictly controlling the ink viscosity, ink scraping angle, ink scraping amount, and ink scraping speed during the screen printing process, and letting the PCB stand still for 15 to 30 minutes after screen printing; (3) pre-baking; (4) exposure; (5) development; (6) appearance inspection; (7) micro-etching; (8) checking the ink color. In step (2), the PCB board after screen printing needs to be laid flat and left still for a period of time, so that the ink can be evenly distributed on the board surface by self-leveling. After standing still for a period of time, the board surface diluent can be volatilized, thereby preventing the board surface from bubbling after subsequent baking.

[0003] In the prior art, PCB boards are generally placed in a static machine for static placement. For example, CN116022540A designed by the present applicant in the early stage discloses a PCB board static machine. By setting at least two sets of lifting components, the PCB board is lifted and lowered in the height direction, and the static placement of the PCB board can be achieved without moving the PCB board out of the assembly line. The static placement time can be adjusted by adjusting the lifting speed of the PCB board in the lifting component. The processing volume of the PCB board can be adjusted by adjusting the height of the lifting component, the number of mounting parts and the board rack, so that the PCB board is in a dynamic and continuous static state, and the static placement time of each PCB board is the same, which can improve the production efficiency while meeting the production quality. However, the inventor of the present application found in the process of using the above-mentioned device that during the loading and unloading process on the lifting component, the board rack and the mounting part adopt a detachable connection method of overlapping, each overlapping part has a horizontal bottom surface and the mounting part is set as a bending part with a flat plate portion, and the flat plate portion overlaps the horizontal bottom surface of the overlapping part to support the board rack. The realization of this method relies on the accuracy of the upward movement of the board rack and the elastic force of the spring of the overlapping parts. When the board rack deviates sideways or the spring force between the overlapping parts is uneven during the upward movement of the board rack, it is easy to cause the board rack to tilt and partially not overlap in place, which in turn causes the board rack to be stuck and unable to move in the X direction. For this reason, the inventor of the present application has further optimized the design of the structure of the original equipment on the basis of the original equipment, replacing the overlapping loading method with the up and down movement of the PCB board conveying assembly, thereby avoiding the board rack from being stuck.

[0042] Embodiment 1: This embodiment discloses a PCB board static device, as shown in 1 to 6, including:

[0043] Rack 1;

[0044] The lifting assembly 2 is provided with two groups in the left and right distribution in the frame 1, including a supporting assembly 21 and a chain assembly 22. Each group of the lifting assembly 2 is provided with four chain assemblies 22 that slide up and down in a circular manner. The chain assemblies 22 are arranged in the frame 1 at the four corners of the front, back, left and right. A plurality of supporting assemblies 21 are evenly installed between the chain assemblies 22 on the left and right sides. The supporting assemblies 21 are provided with a flat plate portion 211 toward the inner side of the frame 1;

[0045] The plate rack 3 is detachably placed on the two horizontally positioned flat plate portions 211, and can be moved up and down inside the frame 1 driven by the lifting assembly 2;

[0046] The horizontal conveying and lifting assembly 4 is installed on the frame 1 below the lifting assembly 2, and includes a horizontal conveying assembly 41 and a lifting assembly 42. The horizontal conveying assembly 41 can move the PCB board 5 in the left-right direction; the lifting assembly 42 can move the horizontal conveying assembly 41 in the up-down direction;

[0047] The transport assembly 6 is provided with two groups, which are respectively located above and below the two groups of lifting assemblies 2 and installed on the frame 1, and are used to drive the uppermost or lowermost plate rack 3 to move left and right, so that the plate rack 3 can be moved from the lifting assembly 2 on one side to the lifting assembly 2 on the other side.

[0048] Embodiment 2: This embodiment is a specific design of the structure based on Embodiment 1, wherein:

[0049] like Figure 7 As shown, the horizontal conveying assembly 41 includes a first driving assembly 411, a roller assembly 412, a lifting frame 413 and an avoidance groove 414; the first driving assembly 411 is fixedly installed on the lower side of the lifting frame 413, and the roller assembly 412 is rotatably installed on the upper end of the lifting frame 413. The first driving assembly 411 can drive the roller assembly 412 to rotate, thereby driving the PCB board 5 to move left and right; the upper end of the lifting frame 413 is also provided with an avoidance groove 414, and the avoidance groove 414 is spaced apart from the roller assembly 412.

[0050] The lifting assembly 42 includes a first telescopic member 421 , which is fixedly mounted on the frame 1 , and a telescopic end of which is fixedly connected to the horizontal conveying assembly 41 , and can drive the horizontal conveying assembly 41 to move up and down.

[0051] The lifting assembly 42 also includes a lifting guide assembly 422, which is fixedly mounted on the frame 1 and can provide a guide for the horizontal conveying assembly 41 to move up and down. In this embodiment, the lifting guide assembly 422 is a combination of a guide sleeve and a guide column, wherein the guide sleeve is fixedly mounted on the frame 1, and the guide column is fixed to the lower end of the horizontal conveying assembly 41.

[0052] like Fig.10 As shown, the board rack 3 includes a plurality of support rods 31 and two fixed rods 32. The support rods 31 are evenly distributed between the two fixed rods 32. The support rods 31 are used to place the PCB board 5. The positions of the support rods 31 and the avoidance grooves 414 correspond one to one.

[0053] In order to prevent the PCB board 5 from being bumped and scratched, the support rod 31 is coated with a flexible buffer material, such as a plastic tube, a rubber ring, etc. The flexible buffer material coated on the support rod 31 can be partially coated at intervals, but preferably fully coated.

[0054] like Fig.11 As shown, a horizontal conveying wheel 321 is provided on the lower side of the fixing rod 32, a guide wheel 322 is provided on the side of the fixing rod 32 away from each other, and horizontal conveying wheels 321 are also provided at both ends of the fixing rod 32. The arrangement of the horizontal conveying wheels 321 allows the plate rack 3 to move smoothly left and right on the flat plate portion 211, thereby preventing the PCB board 5 from moving relative to the support rod 31 due to inertia during sudden movement; the guide wheel 322 can prevent the sliding friction between the side surface and the supporting assembly 21 during the left and right movement of the plate rack 3, resulting in unstable movement or jamming.

[0055] like Figure 3 As shown, the left and right sides of the lifting assembly 2 are provided with limit members 12 for limiting the left and right movement of the plate rack 3, and the limit members 12 avoid the uppermost and lowermost ends of the lifting assembly 2, so that the plate rack 3 located at the uppermost and lowermost ends can move left and right, thereby being able to move from one lifting assembly 2 to another lifting assembly 2.

[0056] like Figure 3As shown, the transport component 6 includes a second drive component 61, a belt component 62, a clamping component 63 and a slide rail 64. The second drive component 61 and the slide rail 64 are installed on the frame 1. The second drive component 61 drives the belt component 62 to move left and right. The clamping component 63 can slide left and right on the slide rail 64, and the clamping component 63 is fixedly connected to the belt component 62 and will move left and right with the belt component 62. The clamping component 63 can clamp the support rod 31 of the plate rack 3, thereby driving the plate rack 3 to move left and right.

[0057] Among them, the clamping and conveying assembly 63 includes a clamping member 631, a sliding plate 632, a second telescopic member 633 and a clamping body 634. The clamping member 631, the sliding plate 632 and the second telescopic member 633 are fixedly connected. The clamping member 631 is clamped on the belt of the belt assembly 62. The sliding plate 632 is slidably connected to the slide rail 64. The telescopic part of the second telescopic member 633 is fixedly connected to the clamping body 634. When the second telescopic member 633 is extended, the clamping body 634 can be clamped to the support rod 31 of the plate rack 3.

[0058] In this embodiment, the PCB board 5 enters from the lower left side and flows out from the lower right side. In other embodiments of the present invention, this process can also be reversed, which is specifically determined according to the placement of the workshop equipment. The specific process of using the device to place the PCB board 5 is as follows:

[0059] First, if Figures 4 to 7 As shown, the PCB board 5 flows into the present device from the previous process, controls the first telescopic member 421 on the left to extend, and drives the horizontal conveying component 41 to rise, as shown in FIG. Figure 8 , Fig. 9 As shown, the support rod 31 of the board rack 3 located above the horizontal conveying assembly 41 enters the avoidance groove 414 until the roller assembly 412 is slightly higher than the support rod 31, and the first driving assembly 411 is started to drive the roller assembly 412 to rotate, thereby driving the PCB board 5 to move right. At this time, the horizontal conveying and lifting assembly 4 on the left side transports the PCB board 5 of the previous process into the equipment, while the horizontal conveying and lifting assembly 4 on the right side transports the PCB board 5 that has been statically placed out of the device and enters the next process. When the PCB board 5 entering on the left side is completely entered and the PCB board 5 on the right side is completely discharged, the first driving assembly 411 is stopped to complete the horizontal conveying of the PCB board 5; then the first telescopic member 421 is controlled to retract, thereby driving the horizontal conveying assembly 41 to move downward, so that the PCB board 5 on the left side falls onto the support rod 31 and is lifted by the support rod 31. After the first telescopic member 421 is retracted, the lifting assembly 2 on the left side is controlled to move up one station, as shown in FIG. Figure 5 , Figure 6As shown, at this time, the plate rack 3 on which the limiting member 12 has just been placed is limited by the limiting member 12 and can only move up and down with the lifting member 2. At this time, the supporting assembly 21 at the lowest end on the left side is in a state without the plate rack 3, and then the transportation assembly 6 below is controlled to transfer the plate rack 3 without the PCB board 5 at the lowest right side to the supporting assembly 21 at the lowest left side. The specific process is: first control the second telescopic member 633 to extend so that the clamping body 634 clamps the support rod 31, and then start the second driving assembly 61 to drive the belt assembly 62 to move, and then drive the clamping assembly 63 to move through the entraining member 631, and finally drive the plate rack 3 to move. When the plate rack 3 moves to the position, the second driving assembly 61 stops, and the second The telescopic member 633 retracts, and then the second driving assembly 61 is controlled to reverse, so that the transport assembly 6 is reset and waits for the next moving task; when the bottom plate rack 3 on the right side moves to the left side, the lifting assembly 2 on the right side is controlled to move down one station, and then the upper transport assembly 6 is controlled to move the plate rack 3 located at the top of the left side to the right to the supporting assembly 21 on the right. At this time, consistent with the initial state, the above process is repeated, so that each PCB board 5 enters from the lower end of the left side, and then gradually moves up, moves to the right after reaching the top, and then gradually moves down, and flows out after reaching the bottom, ensuring that the time for each PCB board 5 from entering the device to flowing out of the device is consistent, and the entire process is automatically operated to ensure the consistency of the static process.

[0060] It can be seen from the above process that the static device can lift and lower the PCB board 5 in the height direction through the cooperation of the lifting component 2 and the board rack 3, and can realize the static state of the PCB board 5 without moving the PCB board 5 out of the production line. The static time can be adjusted by adjusting the lifting speed of the PCB board 5 in the lifting component 2, and the processing amount of the PCB board 5 can also be adjusted by adjusting the height of the lifting component 2, the number of the supporting component 21 and the board rack 3. When the parameters are set, the static time experienced by each PCB board 5 entering the static device is the same, which ensures the consistency of the product and meets the production quality while improving the production efficiency.

[0061] Embodiment 3: This embodiment is another structure of a PCB board static device provided on the basis of Embodiment 1. The device includes a cabin door 11 installed on the left and right sides of the frame 1. The lower end of the cabin door 11 has an opening for the PCB board 5 to pass through. This structure is suitable for situations where the temperature of the PCB board 5 needs to be controlled during the static process, reducing heat exchange with the outside world and reducing insulation energy consumption.

[0062] Embodiment 4: This embodiment is based on Embodiment 3, in which an air inlet fan is provided on the cabin door 11, and an exhaust fan is provided on the top of the rack 1, so that air enters from the air inlet fan on the cabin door 11, blows through the stationary PCB board 5, and then is discharged from the exhaust fan on the top of the rack 1. This structure is suitable for the situation where volatile substances will evaporate during the stationary process of the PCB board 5, and keeps the air in the workshop clean.

[0063] The above describes the main technical features and basic principles of the utility model and the related advantages. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary specific implementations, and the utility model can be implemented in other specific forms without departing from the concept or basic features of the utility model.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
