Description

Technical Field

[0001] The present invention belongs to the technical field of circuit board production, and in particular relates to a storage rack for circuit board production and a method of using the same. Background Art

[0002] Circuit boards miniaturize and visualize circuits, playing a vital role in the mass production of fixed circuits and optimizing the layout of electrical appliances. A printed circuit is typically a conductive pattern of printed wiring, printed components, or a combination of both, created according to a predetermined design on an insulating material. The conductive pattern on the insulating substrate that provides electrical connections between components is called a printed wiring. The resulting printed circuit board is then called a printed wiring board, also known as a printed board or printed circuit board.

[0003] Storage racks are required in the production process of circuit boards. However, some existing storage racks do not fix the circuit boards when storing them, resulting in the problem that the circuit boards are not placed firmly and are easy to scatter. As a result, when the storage racks containing the circuit boards are transported, the circuit boards may shift and fall.

[0004] The Chinese invention patent CN107932460A, published on the publication date, discloses a storage rack for circuit board production. This technology uses an electric telescopic rod to drive a pressure plate to move and press the circuit board, making the circuit board less likely to shift, scatter, or offset, and providing more stable storage for the circuit boards. However, this patent cannot dissipate heat from the circuit boards. Since the circuit boards have a high temperature after production, directly stacking them can easily cause the circuit boards to bend or warp, affecting their quality and wasting resources. It is necessary to dissipate heat and cool the circuit boards to a suitable temperature, making storage safer and more stable to protect the quality of the circuit boards. Summary of the Invention

[0057] S1: First, push the completed circuit boards into the limiting slots in order. The limiting slots can limit the position of the circuit boards. After all the circuit boards are placed, enter S2.

[0058] S2. Start the cylinder. The cylinder piston rod extends and drives the connecting rod to move to the right. The connecting rod drives the movable plate and the positioning protrusion on the movable plate to move until they contact the circuit board. The movable plate and the positioning protrusion can clamp the circuit board to prevent the circuit board from bending or warping.

[0063] S7. Push the bottom plate to drive the universal wheels to move on the ground, which is easy to move.

[0064] The beneficial effects of the present invention are:

[0065] 1. The heat dissipation fan is used to dissipate heat from the circuit board and reduce the temperature inside the shell, so that the temperature inside the shell is kept at a constant temperature. This makes the storage of the circuit board more stable and safe, ensuring that the circuit board will not short-circuit due to excessive temperature, thereby protecting the quality of the circuit board.

[0066] 2. The exhaust fan generates suction to extract the heat inside the shell and release the extracted heat outside the shell, thereby realizing heat transfer inside the shell to ensure that the temperature inside the shell can be maintained at a constant temperature, preventing excessive heat from affecting the safety and stability of the circuit board;

[0067] 3. The connecting rod is driven to move to the right by the cylinder piston rod. The connecting rod drives the movable plate and the positioning protrusion to move to the right until they contact the circuit board, thereby clamping the circuit board. In this way, the circuit board can be clamped to prevent the circuit board from falling due to deviation.

[0068] 4. The motor is used as a driving force to drive the ball screw to rotate, and the guide frame drives the fixed rod and the storage rack body to move forward. The storage rack body drives the circuit board to move forward. The staff then takes and places the moved circuit board. In this way, the auxiliary circuit board can be moved out of the shell, making it easier to take and place the circuit board.

[0069] 5. The guide frame drives the wedge block to move forward to squeeze the contact plate. The contact plate drives the slide bar to move to the right. The slide bar then drives the positioning plate to move to the right until it contacts the limit plate. The limit plate and the positioning plate can limit the pushed-out circuit board to prevent the circuit board from moving. This can achieve the effect of limiting the removed circuit board.

[0070] 6. The universal wheels allow it to move on the ground, making it easy to move and use the circuit board to the designated location. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0078] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0079] In the description of this application, it should be noted that the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship. Technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but where appropriate, technologies, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, so once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0080] Example 1:

[0081] like Figures 1-6 As shown, this embodiment provides a storage rack 4 for circuit board production and a method for using the same, including:

[0082] A base plate 1, on which a housing 2 for storing a circuit board is provided;

[0083] The partitions 3 are arranged in the shell 2 and are spaced apart along the length direction of the shell 2;

[0084] The storage rack body 4 is arranged on one side of the partition 3;

[0085] The limiting groove 5 is provided on the storage rack body 4;

[0086] The clamping assembly 7 is provided in the housing 2 and cooperates with the storage rack body 4 to clamp the circuit board placed in the limiting groove 5;

[0087] and a heat dissipation assembly 6, disposed in the housing 2, for dissipating heat from the produced circuit board;

[0088] There are multiple mounting plates 61, which are arranged in the housing 2 and spaced apart along the length direction of the housing 2;

[0089] There are a plurality of mounting slots 62 provided on the mounting plate 61;

[0090] The heat dissipation fan 63 is disposed in the mounting groove 62 , and the heat dissipation fan 63 and the mounting groove 62 are disposed parallel to the mounting plate 61 .

[0091] In the present technical solution, since the circuit boards have a relatively high temperature after production, and the circuit boards themselves have a certain temperature, if they are stacked directly, it is easy for the circuit boards to bend or warp, affecting the quality of the circuit boards. Therefore, the heat dissipation fan 63 generates wind force to dissipate heat for the circuit boards and reduce the temperature inside the shell 2, so that the temperature inside the shell 2 is maintained at a constant temperature, which makes the storage of the circuit boards more stable and safe, thereby ensuring that the circuit boards will not short-circuit due to excessive temperature.

[0092] Specifically, when it is necessary to store the completed circuit boards, the staff will first push the circuit boards into the limit slots 5 in turn. The limit slots 5 can limit the circuit boards, and the clamping components 7 can clamp the circuit boards to prevent the circuit boards from bending, warping, etc. At the same time, it can prevent the circuit boards from being placed loosely and easily scattered, as well as the circuit boards from shifting and falling. After all the circuit boards are placed, the staff will turn on the cooling fan 63. The cooling fan 63 will generate wind force, and the wind force will dissipate the heat from the circuit boards to ensure that the circuit boards can be kept at a constant temperature and better store the circuit boards. When the circuit boards do not need to be cooled, the cooling fan 63 will be turned off, and finally the circuit boards can be stored, and the temperature inside the shell 2 can be kept at a constant temperature, and the circuit boards can be cooled to ensure that the storage of the circuit boards is safer and more stable, and the quality of the circuit boards can be protected.

[0093] like Figure 1 and Figure 3 As shown, in this embodiment, the optimization further includes an auxiliary component 8, which is arranged above the housing 2 and is used to assist the heat dissipation fan 63 to accelerate the heat dissipation work;

[0094] Among them, the auxiliary component 8 includes:

[0095] The protective shell 81 is disposed on the housing 2, and the protective shell 81 passes through and extends out of the housing 2 and is in communication therewith;

[0096] The exhaust fan 82 is disposed in the protective shell 81 .

[0097] In the present technical solution, when it is necessary to lower the temperature inside the shell 2, the exhaust fan 82 is started, and the exhaust fan 82 generates suction to extract the heat inside the shell 2 and release the extracted heat to the outside of the shell 2, thereby realizing heat transfer of the heat inside the shell 2 to ensure that the temperature inside the shell 2 can be maintained at a constant temperature, preventing excessive heat from affecting the safety and stability of the circuit board. The protective shell 81 can protect the exhaust fan 82 to prevent the staff from accidentally touching the exhaust fan 82 and causing harm, and at the same time prevent other installed components from falling and damaging the exhaust fan 82. When there is no need to dissipate heat inside the shell 2, the exhaust fan 82 can be turned off.

[0098] Example 2:

[0099] This embodiment provides a storage rack for circuit board production and a method for using the same. In addition to the technical solutions of the above embodiments, it also has the following technical features.

[0100] like Figure 1 As shown, in this embodiment, the protective shell 81 is optimized to have a plurality of heat dissipation slots 83 .

[0101] In this technical solution, the exhaust fan 82 extracts the heat and releases it to the outside of the shell 2 through the heat dissipation slots 83, thereby achieving heat dissipation of the shell 2.

[0102] like Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the clamping assembly 7 is optimized to include:

[0103] There are two first guide rods 71, which are arranged between the two sides of the partition 3;

[0104] The movable plate 72 is slidably disposed between the two first guide rods 71 ​​, and the number of the movable plates 72 is consistent with the number of the storage rack bodies 4 and corresponds one to one;

[0105] There are a plurality of positioning protrusions 73, which are arranged on the opposite surfaces of the adjacent movable plates 72 and the partitions 3;

[0106] A connecting rod 74 is slidably disposed in the housing 2 , and the connecting rod 74 is connected to the plurality of movable plates 72 ;

[0107] A first bracket 75 is provided on one side of the housing 2;

[0108] The cylinder 76 is disposed on the first bracket 75 , and the piston rod of the cylinder 76 is fixedly connected to the connecting rod 74 .

[0109] When the PCB board is to be fixed on the rack body 4, the staff starts the cylinder 76, and the piston rod of the cylinder 76 extends to drive the connecting rod 74 to move to the right. The connecting rod 74 drives the movable plate 72 to move to the right along the first guide rod 71. The movable plate 72 drives the positioning protrusion 73 to move to the right until it contacts the PCB board. The positioning protrusions 73 on both sides contact the PCB board, thereby clamping the PCB board to prevent displacement or offset. The storage of the PCB board is more secure. When the circuit board is to be taken out, the piston rod of the control cylinder 76 is retracted, and the piston rod of the cylinder 76 drives the connecting rod 74 to move to the left, and the connecting rod 74 drives the movable plate 72 to move to the left along the first guide rod 71, and the movable plate 72 drives the positioning protrusion 73 to move to the left until it is out of contact with the circuit board. At this time, the positioning protrusion 73 will not clamp the circuit board, and the staff can take out the circuit board. After the operation is completed, the cylinder 76 is closed, and finally the circuit board can be clamped to prevent the circuit board from bending, warping, offsetting and falling, making the circuit boards more secure and neatly stored.

[0110] like Figure 1 As shown, in this embodiment, it is optimized and further includes a pushing component 9 for pushing out the storage rack body 4 to facilitate the taking and placing of the circuit board.

[0111] In this technical solution, the circuit board is assisted in being removed by pushing out the component 9, thereby facilitating the taking and placing of the circuit board and being convenient to use.

[0112] As shown in the picture, Figure 4 、 Figure 5 and Figure 6 As shown, in this embodiment, the optimized ejection component 9 includes:

[0113] The first ear plates 90 are provided on both sides of the partition plate 3;

[0114] The second guide rod 91 is disposed between the two first ear plates 90;

[0115] The slider 92 is provided on the storage rack body 4 and is slidably connected to the second guide rod 91;

[0116] The frame 93 is provided on the housing 2 on the other side of the first bracket 75;

[0117] Motor 94, mounted on frame 93;

[0118] The second bracket 95 is provided on the bottom plate 1;

[0119] A ball screw 96 is rotatably mounted on the second bracket 95 and is connected to the output shaft of the motor 94;

[0120] A third guide rod 97 is provided on the front side of the housing 2 and is adjacent to the ball screw 96;

[0121] The fixing rod 98 is provided on the storage rack body 4;

[0122] The guide frame 99 is slidably disposed on the third guide rod 97 . The guide frame 99 is threadedly connected to the ball screw 96 . The fixing rod 98 is fixedly connected to the guide frame 99 .

[0123] In this technical solution, when it is necessary to assist the circuit board to be moved out, the motor 94 is started, and the output shaft of the motor 94 drives the ball screw 96 to rotate, and then the guide frame 99 moves forward along the third guide rod 97, and the guide frame 99 drives the fixed rod 98 to move forward, and the fixed rod 98 drives the storage rack body 4 to move forward, and the storage rack body 4 drives the slider 92 to move forward along the second guide rod 91, and the second guide rod 91 guides the storage rack body 4. At the same time, the storage rack body 4 drives the circuit board to move forward, and the staff can now take out the circuit board. When the circuit board is taken out, the output shaft of the control motor 94 is reversed, and the output shaft of the motor 94 drives the ball screw 96 to reverse, and the guide frame 99 moves backward along the third guide rod 97, and the guide frame 99 drives the fixed rod 98 to move backward, and the fixed rod 98 drives the storage rack body 4 to move backward, and the storage rack body 4 drives the slider 92 to move backward along the second guide rod 91. When the storage rack body 4 moves backward to the reset position, the staff turns off the motor 94, so that the auxiliary circuit board can be moved out of the shell 2, which is convenient for taking and placing the circuit board and is easy to use.

[0124] like Figure 1 、 Figure 5 and Figure 6 As shown, in this embodiment, the optimization further includes a positioning component 10, which is provided on the bottom plate 1 and is used to position the circuit board after being pushed out;

[0125] Wherein, the positioning component 10 includes:

[0126] There are two third brackets 101, which are arranged on both sides of the bottom plate 1;

[0127] There are two fourth guide rods 102, which are respectively arranged between the two sides of the third brackets 101;

[0128] The fixing plate 103 is provided on the fourth guide rod 102 on the upper side. The fixing plate 103 is distributed along the length direction of the fourth guide rod 102. The fixing plate 103 is located on the front side of the storage rack body 4 and is staggered with the limiting groove 5.

[0129] There are multiple positioning plates 104, which are slidably disposed between the two fourth guide rods 102 and distributed along the length direction of the fourth guide rods 102;

[0130] The second ear plate 105 is provided on one side of the bottom plate 1;

[0131] A slide bar 106 is slidably disposed on the second ear plate 105 , and the slide bar 106 is fixedly connected to the positioning plate 104 ;

[0132] Wedge block 107, provided on one side of the guide frame 99;

[0133] The contact plate 108 is disposed on the slide bar 106 , and the wedge block 107 and the inclined surface of the contact plate 108 are in contact with each other;

[0134] The elastic member 109 is disposed between the contact plate 108 and the second ear plate 105 . The elastic member 109 provides an elastic force to the contact plate 108 to move to the right.

[0135] In the present technical solution, since the circuit board is not clamped when it is pushed out of the shell 2, the circuit board is prone to scattering due to loose placement or falling due to offset of the circuit board. Therefore, it is necessary to limit the circuit board during the removal process to prevent the circuit board from falling due to offset. When the guide frame 99 moves forward, it drives the storage rack body 4 to move forward, and the storage rack body 4 drives the circuit board to move forward and out. The circuit board moves forward until it contacts the left side of the fixed plate 103. At the same time, the guide frame 99 drives the wedge block 107 to move forward. The wedge block 107 squeezes the contact plate 108 to move to the right. The elastic member 109 is stretched, and the contact plate 108 drives the slide bar 106 to move to the right along the second ear plate 105. The slide bar 106 drives the fixed plate 103 The positioning plate 104 moves to the right, and the positioning plate 104 moves to the right until it contacts the circuit board. The circuit board is limited by the positioning plate 104 and the fixing plate 103, so that the circuit board is not easily displaced or offset, and the circuit board is more stable when it is removed. At this time, the staff will take out the removed circuit board. After the circuit board is taken out, the guide frame 99 drives the storage rack body 4 to move backward and reset. At the same time, the guide frame 99 drives the wedge block 107 to move backward until it is out of contact with the contact plate 108. Under the reset action of the elastic member 109, the contact plate 108 drives the slide bar 106 to move to the left, and the slide bar 106 drives the positioning plate 104 to move to the left and reset. In this way, the circuit board can be limited during the removal process of the circuit board, preventing the circuit board from being stored loosely due to offset, and making the circuit board storage more stable.

[0136] like Figure 6 As shown, in this embodiment, it is optimized that the elastic member 109 is a return spring.

[0137] In this technical solution, a return spring is used as the elastic member 109, which not only has a good effect, but also has the characteristics of easy installation and low price, thus saving production costs.

[0138] like Figure 1 and Figure 6 As shown, in this embodiment, the optimization further includes a moving component 11 for driving the bottom plate 1 to move;

[0139] The mobile component 11 includes:

[0140] There are four universal wheels 111 , which are respectively arranged on four sides of the bottom of the base plate 1 .

[0141] In this technical solution, when the placed circuit board needs to be moved, the staff pushes the base plate 1, and the base plate 1 drives the universal wheel 111 to move on the ground. After the circuit board is moved to the designated position, the staff stops pushing the base plate 1. In this way, the circuit board can be conveniently transported to the designated position and moved easily.

[0142] like Figures 1-6 As shown, in this embodiment, the optimization includes the following steps:

[0143] S1. First, push the completed circuit boards into the limiting grooves 5 in order. The limiting grooves 5 can limit the position of the circuit boards. After all the circuit boards are placed, enter S2.

[0144] S2. Start the cylinder 76. The piston rod of the cylinder 76 extends, driving the connecting rod 74 to move to the right. The connecting rod 74 drives the movable plate 72 and the positioning protrusion 73 on the movable plate 72 to move until they contact the circuit board. The movable plate 72 and the positioning protrusion 73 can clamp the circuit board to prevent the circuit board from bending or warping.
