Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of circuit board drilling code processing, and particularly relates to a pressing plate passing device for circuit board drilling code. BACKGROUND

[0002] As the carrier of electronic components and the basis of circuit interconnection, the drilling code process of a printed circuit board (PCB) directly affects the reliability of electrical connection. In the drilling code process, a backing plate plays a key role: preventing damage to the plate surface by a drill bit, reducing outlet burrs (flashes), and assisting in chip removal. In the traditional process, the backing plate will accumulate wear and tear after continuous use, resulting in a decrease in hole quality, including an increase in burr height, deterioration of hole wall roughness, and other problems.

[0003] Currently, the industry generally adopts a manual backing plate replacement method, and a new backing plate is replaced after each PCB is processed. Although this method can ensure drilling code quality, it has obvious drawbacks: frequent downtime for plate replacement leads to reduced production efficiency, forming an efficiency bottleneck on the automatic production line; and manual operation increases the cost of the drilling code process. With the development of high-density PCBs (hole diameter ≤ 0.2 mm), higher requirements are placed on the performance and replacement method of the backing plate, and a more efficient backing plate management solution is urgently needed to balance quality and cost.

[0004] The identification code drilled by the drilling machine can be any one of a two-dimensional code, a bar code, and an anti-fake code, or other identification codes commonly used in the art. In the present application, a two-dimensional code is mainly described. The two-dimensional code is a DataMatrix two-dimensional code generated by a user-set character information system. The DataMatrix two-dimensional code has the characteristics of small size, a minimum drilling code number of 10*10 matrix, and strong error correction. The two-dimensional code is a black-and-white pattern that records data symbol information in a certain pattern on a plane (two-dimensional direction). It cleverly uses the concept of "0" and "1" bit stream, which is the basis of computer internal logic, to represent text and numerical information using several geometric shapes corresponding to binary. It can be automatically recognized and processed through image input devices or photoelectric scanning devices. It has some common features of bar code technology, such as a specific character set for each code, a certain width for each character, and a certain check function. It also has automatic identification function for different rows of information and processing of graphical rotation changes. The matrix identification code pattern corresponds to the identification code, and the matrix identification code pattern is in a proportional scaling relationship with the identification code. The preset area can be defined according to user needs, as long as it is set in a position that is easy to find.

DETAILED DESCRIPTION

[0052] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be described clearly and completely below with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0053] The terms "first", "second", "third", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an indicated number of features so limited. Thus, a feature limited to "first", "second", etc. can explicitly or implicitly include one or more of such features; in the description of the present application, the meaning of "a plurality" is two or more, unless otherwise stated.

[0054] The terms of the present application are explained as follows, and the specific meanings are referred to the specific application scenarios of the corresponding embodiments 1 to 6.

[0055] The material tape in the present application is a flexible material tape (also known as a pad, such as an aluminum tape, a paper tape, a phenolic plate, etc.). The material tape can be wound into a roll shape, so as to be fixed on the upper feeding roll or the lower feeding roll of the material tape device in embodiment 1. The upper feeding roll and the lower feeding roll can rotate relative to the support. When the material tape is forced, the upper feeding roll or the lower feeding roll will rotate so as to make the material tape be pulled out to a certain length. The length of the material tape can be set according to actual needs, so as to ensure that the same roll of material tape can meet the drilling code work of multiple circuit boards, without frequent replacement of the material tape, thereby improving the production efficiency. The upper feeding roll and the upper driving mechanism are provided. The upper driving mechanism is used to drive the upper material collecting roll to rotate, so as to make the used material tape be wound on the upper material collecting roll in a roll shape, thereby avoiding disorder. The lower feeding roll and the lower driving mechanism have the same principle and effect. Of course, in actual operation, a material collecting device can be provided to replace the upper material collecting roll and the lower material collecting roll to collect the used material tape, wherein the material collecting device can be a material collecting frame, a material collecting barrel, etc.

[0056] The processing parameter in the present application refers to the drilling code file data of the drilling machine. The drilling machine can drill a specified pattern or pattern on the circuit board according to the processing parameter.

[0057] The technical scheme of the present application will be described below in combination with Figures 1 to 23 and the following embodiments.

[0058] Embodiment 1

[0059] As Figure 1 shown, it is a material tape device for a middle-through type drilling machine in the present embodiment. The material tape device has an up-and-down opening and closing structure, which comprises a support, an upper material tape assembly, a lower material tape assembly and a first driving assembly 4. The upper material tape assembly is arranged at the upper part of the drilling platform, and is used to control the movement of the material tape above the circuit board. The lower material tape assembly is arranged at the lower part of the drilling platform, and is used to control the movement of the material tape below the circuit board. The first driving assembly 4 is arranged between the upper material tape assembly and the lower material tape assembly, and is used to lift the material tape above the circuit board, so as to make the material tape above the circuit board adhere to or separate from the circuit board. When the material tape is separated, the finished circuit board can pass through the hollow stepped structure.

[0060] The feeding and unloading conveyor belts work together to control the movement of the conveyor belts. Specifically, during the alternating processing of circuit board coding, the feeding and unloading conveyor belts control the movement of the conveyor belts located above and below the circuit board, respectively, to update the upper and lower conveyor belts when processing a new circuit board.

[0061] Another implementation of this embodiment includes a support, a feeding belt assembly, and a first drive assembly 4. The feeding belt assembly is disposed on the upper part of the drilling platform and controls the movement of the feeding belt located above the circuit board; the first drive assembly 4 is disposed between the feeding belt assembly and the support, and is used to raise and lower the feeding belt located above the circuit board, so that the feeding belt located above the circuit board is attached to or separated from the circuit board. When separated, the processed circuit board can pass through the hollow stepped structure.

[0062] In this embodiment, the strip above the circuit board can be aluminum strip, and the strip below the circuit board can be paper strip. During the circuit board coding process, the paper strip is placed below and the aluminum strip is placed above. The strips can be made of the same or different types of aluminum strip, paper strip, or other flexible materials.

[0063] like Figure 1 The diagram shows the material strip device for a through-type drilling machine according to this embodiment. The material strip device includes a bracket, an upper cover plate material strip assembly, a lower pad plate material strip assembly, and a first drive assembly 4. The upper cover plate material strip assembly is located on the upper part of the drilling platform and controls the movement of the material strip located above the circuit board (the material strip above the circuit board can also be called the upper cover plate or the upper material strip). The lower pad plate material strip assembly is located on the lower part of the drilling platform and controls the movement of the material strip located below the circuit board (the material strip below the circuit board can also be called the lower pad plate or the lower material strip). The first drive assembly 4 is located between the upper cover plate material strip assembly and the lower pad plate material strip assembly, and is used to raise and lower the material strip located above the circuit board, causing the material strip above the circuit board to adhere to or separate from the circuit board.

[0064] The upper cover plate material strip assembly and the lower pad plate material strip assembly work together to control the movement of the material strip. Specifically, during the alternating processing of circuit board coding, the upper cover plate material strip assembly and the lower pad plate material strip assembly control the movement of the material strips located above and below the circuit board, respectively, to complete the renewal of the upper and lower material strips when processing a new circuit board.

[0065] In this embodiment, the strip above the circuit board can be aluminum strip, and the strip below the circuit board can be paper strip. During the circuit board coding process, the paper strip is placed below and the aluminum strip is placed above. The strips can be made of the same or different types of aluminum strip, paper strip, or other flexible materials.

[0066] In this embodiment, the first driving assembly 4 can control the up-down movement of the upper cover plate and the material tape assembly as a whole, so as to realize the attachment or separation of the circuit board and the material tape located above the circuit board. The first driving assembly 4 is a pneumatic cylinder, so as to drive the material tape to move up and down. It should be noted that the setting mode of the first driving assembly 4 is not limited to this, for example, the first driving assembly 4 can also be a motor, which can also drive the material tape to move up and down.

[0070] When the upper driving mechanism 24 drives the upper collecting disc 222 to rotate, so as to drive the third roller 233 and the fourth roller 234 to rotate, the third roller 233 and the fourth roller 234 will drive the material tape to move forward, and the first roller 231 and the second roller 232 will also guide the new material tape to be taken out from the upper feeding reel 21, so as to realize the purpose of automatically replacing the material tape located above the circuit board.

[0074] When the lower driving mechanism 34 drives the lower collecting disc 322 to rotate, thereby driving the seventh roller 333 and the eighth roller 334 to rotate, the seventh roller 333 and the eighth roller 334 will drive the material tape to move forward, and the first roller 231 and the second roller 232 will also guide the new material tape to be taken out from the lower feeding reel 31, so that the purpose of automatically replacing the material tape below the circuit board can be achieved.

[0086] When it is necessary to replace the tape below the circuit board, first, the lower drive mechanism 34 is controlled by the controller to drive the lower collecting disc 322 to rotate, thereby driving the tape below the circuit board to advance by a preset distance; after the tape below the circuit board advances by the preset distance, the controller controls the lower drive mechanism 34 to stop driving, thereby realizing the process of automatically replacing the tape below the circuit board.

[0087] Embodiment 2

[0088] The embodiment provides a pressing plate passing device for drilling codes on a circuit board, as shown in Figure 4 and Figure 5 The pressing plate passing device has a hollow stepped structure, the upper part of the stepped structure is a loading platform 5, the loading platform 5 is provided with a drilling cooperation unit 51, the lower part of the stepped structure is a processing platform 6, the processing platform 6 is provided with a hollow groove 61, the hollow groove 61 is internally provided with a pressing plate assembly 7, and the circuit board can pass through the hollow stepped structure.

[0089] In the embodiment, as shown in Figure 22 from the side, the loading platform 5 can be located above the left of the processing platform 6, as shown in Figure 23As shown, the platform 5 can also be located at the upper right of the processing platform 6. Alternatively, the platform 5 can be located in front of the upper part of the processing platform 6 or behind the upper part of the processing platform 6. The platform 5 and the processing platform 6 form a hollow stepped structure. However, the relative position of the platform 5 and the processing platform 6 is not fixed. When it is necessary to drill code on the circuit board, the drilling equipment moves to the circuit board to drill code.

[0091] By setting up a pressure plate conveyor with a hollow stepped structure, the circuit board that has been processed after entering the drilling and coding processing area from the feeding assembly (feeding device) can be directly conveyed from the hollow part of the stepped structure of the pressure plate conveyor to the unloading area, reducing unnecessary conveying steps, achieving fast and stable board conveying, better connecting processed circuit boards and unprocessed circuit boards, and greatly improving drilling and coding efficiency.

[0092] In this embodiment, as Figures 6-9 As shown, the pressure plate assembly 7 may include a first drive mechanism 71 and a second drive mechanism 72. The first drive mechanism 71 is provided with a first pressure plate member 711 (several members may be provided, such as...). Figure 6 The diagram shows five first pressure plate members 711, each capable of moving vertically (Y-axis direction); the second drive mechanism 72 is equipped with front and rear guide members 721 (several sets can be configured, such as...). Figure 6 Two sets of front and rear guide members 721 are provided (as shown), and the front and rear guide members 721 can move along the front and rear direction (X-axis direction). The first drive mechanism 71 and the second drive mechanism 72 are interconnected, causing the pressure plate assembly 7 to move along the X-axis and Y-axis directions, as shown. Figure 6 As shown, the first drive mechanism 71 and the second drive mechanism 72 are connected by a connecting seat 73, and the second drive mechanism 72 is fixed to the lower part of the processing platform 6.

[0093] like Figure 5 As shown, the pressure plate passing device in this embodiment has several slots 61 on the processing platform 6. The first pressure plate component 711 can move along the X, Y, and Z axes through the slots 61.

[0094] The first drive mechanism 71 can drive the first pressure plate 711 to move up and down via a cylinder or motor. In addition, the second drive mechanism 72 moves back and forth, indirectly driving the connecting seat 73.

[0095] In the embodiment, the longitudinal section of the first pressing plate member 711 can be "┒" shape, "┎" shape or "T" shape. Figure 10 For Figure 6 In the embodiment, the longitudinal section of the first pressing plate member 711 can be "┒" shape, "┎" shape or "T" shape.

[0097] When the first pressing plate member 711 adopts "┎" shape, the driving direction is Y-axis direction, and the "┎" shaped first pressing plate member 711 is rotated along X-axis direction along Y-axis by cooperating with the steering mechanism, so as to realize that when the first pressing plate member 711 presses the circuit board, the pressure head presses the material belt and the circuit board on the drilling and coding platform, and after the drilling and coding of the circuit board is completed, before the circuit board is conveyed out of the processing area, the "┎" shaped first pressing plate member 711 rotates along X-axis direction along Y-axis by a certain angle, so that the pressure head is separated from the drilling and coding platform, and the pressure head falls into the empty slot 61 of the drilling and coding platform, so as to facilitate the circuit board to be conveyed out of the processing area.

[0098] In the embodiment, Figure 11 For Figure 6 In the embodiment, the oblique view of the front and rear guide member 721 is shown in the figure, Figure 6 and Figure 11 As shown in the figure, the front and rear guide member 721 can include a support seat 7211 extending in the front and rear direction and a first sliding block 7212 movably connected with the support seat 7211, the support seat 7211 is fixed on the lower part of the processing platform 6, the first sliding block 7212 is fixedly connected with the connecting seat 73, and the first sliding block 7212 can move along the front and rear direction.

The left and right guide members 731 include two groups of second sliding blocks 7311 and slide rails 7312, the slide rails 7312 are fixed on the lower connecting seat 733, the second sliding blocks 7311 are fixed on the upper connecting seat 732, the second sliding blocks 7311 are movably connected with the slide rails 7312, and the second sliding blocks 7311 can drive the upper connecting seat 732 to move along the left and right direction, so as to drive the first driving mechanism 71 to move along the left and right direction as a whole.

[0100] The left and right guide members 731 can adjust the position of the first pressing plate member 711 on the fixed part of the circuit board.

[0101] In the embodiment, the drill matching unit 51 can include a transfer tool holder 511 and a tool assembly 512, the tool assembly 512 including a tool holder and a tool disc arranged on the tool holder, the transfer tool holder 511 and a tool detector cooperatively achieving automatic replacement of the tool in the tool disc.

In the following embodiment 3, the feeding conveying device 82 corresponds to the “feeding assembly” herein and is used to convey the circuit board to the machining position; the discharging conveying device 87 corresponds to the “discharging assembly” herein and is used to discharge the circuit board after drilling and coding. In the following embodiment 4, the feeding device 84 has the same function as the “feeding assembly” herein and is used to convey the circuit board to the machining position; the discharging conveying device 87 corresponds to the “discharging assembly” herein and is used to move the circuit board after drilling and coding out of the machining position.

[0106] In the embodiment, the processing platform is provided with a blocking device for limiting the circuit board.

The blocking piece (i.e., the blocking device mentioned in the embodiment 2) is used for limiting the circuit board, and the blocking piece can block the movement of the circuit board on the feeding assembly to prevent the circuit board from continuing to move forward after the feeding assembly stops moving.

[0114] Figure 12 An implementation process of a two-stage processing method provided by the embodiment is shown. For ease of description, only parts related to the embodiment are shown, and the two-stage processing method of the embodiment includes the following steps:

[0115] S101, when the circuit board is transported to a preset position, the circuit board is positioned;

[0116] S102. According to the processing parameters of the circuit board, control the drilling device 85 to process the matrix identification code pattern corresponding to the identification code on the circuit board.

[0117] S103. The processed circuit board is transferred out of the drill bit processing area from the hollow stepped structure.

[0118] In this embodiment, as Figure 13 As shown, the two-stage processing method of this application may further include the following steps:

[0119] S104. The processed circuit board is conveyed to the unloading area by the unloading conveyor 87.

[0120] In this embodiment, as Figures 6-9 As shown, the pressure plate assembly 7 may include a first drive mechanism 71 and a second drive mechanism 72.

[0122] In this embodiment, during step S101, when positioning the circuit board, a feeding blocking device prevents the circuit board from continuing to move forward. When the conveying device (or feeding device 84) conveys the circuit board, the circuit board may continue to move forward when the conveying device stops, resulting in inaccurate positioning.

When it moves to the top of the drive groove 924, the wire pressing electromagnet 926 is turned on, generating magnetic force to attract the limit block 925 to rotate, and at the same time, it drives the second pressure plate 91 to rotate. When the wire pressing electromagnet is engaged with the limit block 925, the wire pressing electromagnet 926 is de-energized. At the same time, the drive seat 92 adjusts the height of the second pressure plate 91 by adjusting the inflation amount. The limit plate 922 passes through the limit groove 928 on the drive seat 92 to limit the movement of the second pressure plate 91 and ensure the angle of the second pressure plate 91 during the pressing process.

[0169] After the pressure plate finishes working, the drive seat 92 increases the air volume, the drive block 923 moves upward and separates from the limit plate 922. At the same time, the return electromagnet 927 is energized, generating magnetic force to attract the limit block 925 to rotate until the limit block 925 and the return electromagnet 927 are engaged. After the return electromagnet 927 is engaged, the Z-axis drive cylinder 941 and the X-axis drive cylinder 951 are adjusted to return the second pressure plate component 91 to its original position.

[0170] Of course, in actual operation, the positions of the wire pressing electromagnet 926 and the return electromagnet 927 can be adjusted according to the setting position of the drive seat 92 and the position of the pressure plate movement.
