Description

Technical Field

[0001] The utility model relates to the field of PCB printing equipment, in particular to a PCB semi-automatic printing equipment. Background Art

[0002] PCB printing often involves plugging vias to achieve high reliability and improve performance. This step typically requires the use of an air guide plate to improve plugging efficiency and prevent air bubbles.

[0003] In the use of semi-automatic plugging equipment, the use of a universal air guide plate will cause the plugging holes to turn red, while the use of a dedicated air guide plate will make the production of some small batches of PCBs complicated, increase production costs and reduce efficiency. Utility Model Content

[0004] To address the aforementioned issues, the present invention proposes a semi-automatic PCB printing device that eliminates the need for an air guide plate by adding a protective element, thereby avoiding the issues of reddening of the plug holes, complex production, increased production costs, and low efficiency caused by the air guide plate.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] In a first aspect, the present invention provides a semi-automatic PCB printing device, comprising:

[0007] The machine is provided with a storage board;

[0008] The roller conveying mechanism includes a first roller assembly, a second roller assembly, and a protective member. The first roller assembly and the second roller assembly are respectively arranged on both sides of the machine. The protective member is provided with a reeling portion, a plugging portion, and a reeling portion. The reeling portion is arranged on the first roller assembly, the plugging portion is located above the storage plate, and the reeling portion is arranged on the second roller assembly.

[0009] And a plug hole mechanism is rotatably connected to the machine platform. The plug hole mechanism is provided with a plug hole grid plate. When the plug hole mechanism rotates along the machine platform, the plug hole grid plate is pressed onto the PCB board arranged on the protective component.

[0010] By installing a roller mechanism, a protective piece is positioned between the machine's storage plate and the plugging mechanism. This allows the PCB to rest on the protective piece during plugging, replacing the need for an air guide plate. This prevents the reddening of the plugged holes caused by a universal air guide plate, while also avoiding the increased cost and production complexity associated with dedicated air guide plates. Furthermore, the provision of an unwinding and rewinding section eliminates the need for manual replacement of used protective pieces, reducing errors caused by manual operation.

[0011] In some embodiments, a plurality of positioning devices are further provided on the peripheral side of the storage plate. The positioning device is provided with a first positioning component and a second positioning component. The first positioning component is provided on the second positioning component, and the second positioning component passes through the protective member for positioning.

[0012] In order to prevent the PCB from moving when placed on the protective member, multiple positioning devices are also arranged around the storage plate. The first positioning component is used for coarse positioning, and the second positioning component is used for fine positioning to reduce the sliding of the PCB.

[0013] In some embodiments, the first positioning assembly includes a first positioning piece and a fixing portion; after the positioning piece determines the size of the PCB board, the positioning piece is fixed by the fixing portion.

[0014] The fixing portion is used to prevent the positioning piece from shifting after the first positioning piece is roughly positioned according to the size of the PCB, thereby preventing the PCB from shifting when placed on the protective piece.

[0015] In some embodiments, the second positioning assembly includes a second positioning piece, which is disposed on the first positioning piece and is installed through the protective member when the PCB is installed.

[0016] The second positioning piece is arranged on the first positioning piece. After the first positioning piece is roughly positioned, the second positioning piece is finely positioned by passing through the protective piece to further improve the stability of the PCB on the protective piece.

[0017] In some embodiments, the protective member is white paper or printed paper.

[0018] The protective member can be set as white paper, or printed paper, or some films with protective insulation effects.

[0019] In some embodiments, the first roller assembly and the second roller assembly are both provided with a support frame, a driving unit, and a roller, one end of the support frame is fixed on the machine table, the roller is rolled and arranged at the other end of the support frame, and the driving end of the driving unit is arranged on the roller to drive the roller to roll.

[0020] The first roller assembly and the second roller assembly are both mounted on both ends of the machine through a support frame. The rollers are arranged at the free ends of the support frame. Through the rolling of the rollers, the unwinding part releases the protective piece and the winding part gathers the protective piece for use.

[0021] In some embodiments, the driving portion is a hand crank or a driving motor.

[0022] The driving part can be set to a hand crank for manual operation, or a driving motor for automatic operation.

[0023] In some embodiments, one end of the plugging mechanism is fixed on the machine platform, and the other end of the plugging mechanism can be flipped and set on the machine platform.

[0024] The plugging mechanism is folded and arranged on the machine table to realize PCB plugging.

[0025] In some embodiments, the plugging mechanism includes a moving device and a frame body, the moving device is arranged on the frame body, the moving device includes a first moving device and a second moving device, the second moving device is arranged to move on the first moving device, and the moving directions of the first moving device and the second moving device are perpendicular to each other, and the plugging grid plate is arranged on the second moving device.

[0026] The first moving device and the second moving device enable the plug hole grid plate to be moved laterally in two directions to adjust the position of the plug hole grid plate, thereby aligning the plug hole grid plate with the PCB board placed on the storage plate.

[0027] In some embodiments, the second moving device is further provided with a lifting assembly, and the plug hole grid plate is provided on the lifting assembly.

[0028] The second moving device is provided with a lifting assembly to further adjust the position of the plugging grid plate to adapt to the position of the PCB and thus better perform the plugging process.

[0029] The beneficial effects of the PCB semi-automatic plugging device of the utility model are:

[0030] By installing a rolling mechanism between the machine and the plugging mechanism, the protective piece can be moved between the machine and the plugging mechanism through the rolling mechanism, thereby releasing and retracting the protective piece. By utilizing the protective piece, the use of an air guide plate is avoided, further preventing the plugging hole from reddening when the air guide plate is used, and avoiding the problems of low production efficiency and increased production costs caused by the use of a dedicated air guide plate.

[0047] Example 1:

[0048] like Figure 1 and Figure 2 As shown, this embodiment provides a PCB semi-automatic printing device, including:

[0049] The machine 100 is provided with a storage plate 110;

[0050] The roller conveying mechanism 200 includes a first roller assembly 210, a second roller assembly 220, and a protective member 230. The first roller assembly 210 and the second roller assembly 220 are respectively arranged on both sides of the machine 100. The protective member 230 is provided with an unwinding portion 231, a plugging portion 232, and a rewinding portion 233. The unwinding portion 231 is arranged on the first roller assembly 210, the plugging portion 232 is located above the storage plate 110, and the rewinding portion 233 is arranged on the second roller assembly 220.

[0051] The plugging mechanism 300 is rotatably connected to the machine 100 . The plugging mechanism 300 is provided with a plugging grid plate 310 . When the plugging mechanism 300 rotates along the machine 100 , the plugging grid plate 310 is pressed onto the PCB board provided on the protective member 230 .

[0052] Specifically, the machine 100 is provided with a storage plate 110, which serves as a work area for plugging holes in PCBs. A first roller assembly 210 and a second roller assembly 220 are respectively provided on either side of the machine 100. A protective member 230 is wound on the first and second roller assemblies 210 and 220. The protective member 230 can be stretched from an unwinding section 231 to a plugging section 232, and finally retracted and rewound to a reeling section 233. This allows the protective member 230 to be moved from an unused state in the unwinding section 231 to a used state in the plugging section 232. Finally, the used protective member 230 is retracted within the reeling section 233 to facilitate recycling and avoid reuse. The plugging section 232 is provided above the storage plate 110, so that when the PCB is placed, the protective member 230 is positioned between the PCB and the storage plate 110. During the plugging process, the plugging mechanism 300 is rotated and pressed onto the storage plate 110 so that the plugging grid plate 310 is attached to the PCB, thereby completing the plugging process.

[0053] By installing a roller mechanism 200 and positioning a protective member 230 between the platform 100's storage plate 110 and the plugging mechanism 300, the PCB rests on the protective member 230 during plugging, replacing the need for an air guide plate. The protective member 230 avoids the reddening of the plugged holes caused by a universal air guide plate, as well as the increased cost and production complexity associated with dedicated air guide plates. Furthermore, the provision of an unwinding unit 231 and a rewinding unit 233 eliminates the need for manual replacement of the used protective member 230, reducing errors caused by manual production operations.

[0054] Example 2:

[0055] Based on Example 1 Figure 1 and Figure 2 This embodiment further explains and optimizes the structures of the machine 100 and the rolling mechanism 200 mentioned in Example 1. Figure 3 and Figure 4 As shown,

[0056] In some embodiments, a plurality of positioning devices are further provided around the storage plate 110 , and the positioning device includes a first positioning component 120 and a second positioning component 130 . The first positioning component 120 is provided on the second positioning component 130 , and the second positioning component 130 passes through the protective member 230 for positioning.

[0057] Specifically, a plurality of positioning devices are provided around the storage plate 110. The positioning devices are located around the storage plate 110. The PCB is roughly positioned by the first positioning component 120 and precisely positioned by the second positioning component 130. The first positioning component 120 and the second positioning component 130 can be integrally formed. The second positioning component 130 can be provided with a certain height difference from the plane of the first positioning component 120. The second positioning component 130 passes through the protective component 230 to the side of the PCB board and then abuts against the side of the PCB board for precise limiting.

[0058] In order to prevent the PCB from moving when placed on the protective member 230, a plurality of positioning devices are provided around the storage plate 110. The first positioning component 120 performs coarse positioning, and the second positioning component 130 performs fine positioning to reduce the sliding of the PCB.

[0059] In some embodiments, the first positioning assembly 120 includes a first positioning piece and a fixing portion; after the positioning piece determines the size of the PCB board, the positioning piece is fixed by the fixing portion.

[0060] Specifically, the first positioning piece can be a flat patch in a rectangular shape, and the fixing portion can be adhesive tape. After the first positioning piece is roughly positioned, the adhesive tape is used to fix the positioning piece in place and slide. Further preferably, the first positioning piece can be configured as a rectangle, with one corner of the rectangle fixed to the storage plate 110. The first positioning piece is rotated around the corner and then fixed with adhesive tape in the roughly positioned position.

[0061] The beneficial effect of this method is that the fixing portion is used to prevent the positioning piece from shifting after the first positioning piece is roughly positioned according to the size of the PCB, thereby preventing the PCB from being shifted when placed on the protective member 230 .

[0062] In some embodiments, the second positioning assembly 130 includes a second positioning piece, which is disposed on the first positioning piece and is installed through the protective member 230 when the PCB is installed.

[0063] Specifically, the second positioning piece can be a positioning protrusion, which can be integrally provided on the first positioning piece, or the second positioning piece can be bonded after the position is determined. The second positioning piece, that is, the positioning protrusion in this embodiment needs to be able to pass through the protective piece 230 and actually contact the PCB, thereby achieving the function of accurately positioning the PCB and accurately limiting the PCB.

[0064] The beneficial effect of this method is that the second positioning piece is set on the first positioning piece. After the first positioning piece is roughly positioned, the second positioning piece is finely positioned by passing through the protective piece 230 to further improve the stability of the PCB on the protective piece 230.

[0065] In some embodiments, the protective member 230 is white paper or printed paper.

[0066] Specifically, the protective member 230 may be made of white paper. The beneficial effect of using white paper is that it can reduce costs and reduce production complexity.

[0067] Optionally, the protective member 230 may be configured as printed paper, or some films with protective insulating effects.

[0068] In some embodiments, the first roller assembly 210 and the second roller assembly 220 are both provided with a support frame 240, a driving unit 250, and a roller 260. One end of the support frame 240 is fixed on the machine 100, and the roller 260 is rollingly set at the other end of the support frame 240. The driving end of the driving unit 250 is set on the roller 260 to drive the roller 260 to roll.

[0069] Specifically, the first roller assembly 210 and the second roller assembly 220 are respectively arranged on both sides of the machine 100 through the support frame 240. The support frame 240 can adopt a metal support frame 240 to improve stability. It is fixed to the side of the machine 100 by screws at one end, and the other end is suspended above the storage plate 110. Furthermore, the support frame 240 can be set to an adjustable height form, and then it can be adjusted during use, so that the protective member 230 can be more adapted to the PCB board when plugging the hole. A cross bar can be set at the suspended end of the support frame 240, and the roller 260 is sleeved on the cross bar. The roller 260 is driven to roll by the driving part 250, thereby completing the process of the protective member 230 used for bundling in the winding part 233 from the unwinding part 231 to the plugging part 232 to the winding part 233.

[0070] The beneficial effect of this step is that the first roller assembly 210 and the second roller assembly 220 are both mounted on both ends of the machine 100 through the support frame 240, and the roller 260 is rollingly set at the free end of the support frame 240. The unwinding part 231 releases the protective part 230 through the rolling of the roller 260.

[0071] In some embodiments, the driving unit 250 is a hand crank or a driving motor.

[0072] Specifically, a drive unit 250 is provided at one end of the suspension end crossbar of the aforementioned support frame 240. This can be a crank structured hand crank, which is manually shaken to achieve the rolling of the drum 260. This approach can achieve a simple structure while allowing the protective member 230 to be adjusted according to actual production steps. A drive motor can also be used in place of the aforementioned hand crank. Although this can improve the degree of automation, the production process will be relatively complex. A button or automated monitoring can be provided to control the rotation timing, thereby achieving timely replacement of the protective member 230 to prevent the protective member 230 from being used multiple times.

[0073] The driving part 250 can be provided with a hand crank for manual operation, or can be provided with a driving motor for automatic operation.

[0074] Example 3:

[0075] Based on Example 1 and Example 2 Figures 1 to 4 As shown, this embodiment further explains the relationship between the plugging mechanism 300 proposed in Example 1 and the partial structure proposed in Example 2 and the plugging mechanism 300. Figure 5 shown.

[0076] In some embodiments, one end of the plugging mechanism 300 is fixed on the machine platform 100 , and the other end of the plugging mechanism 300 can be flipped and set on the machine platform 100 .

[0077] Specifically, one end of the plugging mechanism 300 is flipped and fixed to the machine platform 100, and further fixed to an edge of the machine platform 100. The other end of the plugging mechanism 300 is free to flip, so that the plugging mechanism 300 completely covers the storage plate 110 of the machine platform 100. The plugging mechanism 300 is folded and installed on the machine platform 100 to achieve PCB plugging.

[0078] In some embodiments, the plugging mechanism 300 includes a moving device and a frame body 320, the moving device is set on the frame body 320, the moving device includes a first moving device 330 and a second moving device 340, the second moving device 340 is set on the first moving device 330 to move, and the moving directions of the first moving device 330 and the second moving device 340 are perpendicular to each other, and the plugging grid plate 310 is set on the second moving device 340.

[0079] Specifically, the movable device is mounted on the plugging mechanism 300. The frame body 320 can be a rectangular frame, with the movable device positioned between the rectangular frame. The first movable device 330 and the second movable device 340 are mounted on the first movable device 330 and move along one side of the rectangular frame, i.e., perpendicular to the direction of movement of the first movable device 330. The plugging grid plate 310 is mounted on the second movable device 340, allowing the plugging grid plate 310 to be adjusted in two directions to accurately fit the plugging grid plate 310 on the PCB during the plugging process. This advantageous effect is that, through the first movable device 330 and the second movable device 340, the plugging grid plate 310 can be moved laterally in two directions to adjust its position, thereby aligning the plugging grid plate 310 with the PCB placed on the storage plate 110.

[0080] In some embodiments, the second moving device 340 is further provided with a lifting assembly 350 , and the plug hole grid plate 310 is disposed on the lifting assembly 350 .

[0081] Specifically, the second moving device 340 is provided at the location of the plugging grid plate 310 and is provided with a lifting assembly 350. The plugging grid plate 310 is provided on the driving portion 250 of the lifting assembly 350, so that the plugging grid plate 310 can be raised and lowered on the lifting assembly 350. The beneficial effect of this embodiment is that the second moving device 340 is provided with the lifting assembly 350 to further adjust the position of the plugging grid plate 310 to adapt to the position of the PCB and thus better perform the plugging process.
