Detailed Implementation

[0033] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] like Figures 1 to 6 As shown, an embodiment of the present invention provides an alignment mechanism, including a frame 1, a first alignment component 2 and a second alignment component 3. The first alignment component 2 and the second alignment component 3 are both disposed on the frame 1. The frame 1 is provided with a receiving area 4, which is suitable for receiving multiple stacked plates.

[0035] The first alignment component 2 is disposed on one side of the receiving area 4, and the first alignment component 2 is capable of pushing at least a portion of the multiple plates along the first direction;

[0036] The first alignment component 2 can align multiple plates along the edges in a first direction;

[0037] The second alignment component 3 enables multiple boards to be aligned along the edges of a second direction; wherein the first direction intersects the second direction. In this embodiment, the first direction is perpendicular to the second direction. For example, the first direction is the left-right direction (X-direction), and the second direction is the front-back direction (Y-direction). The board is a PCB. Traditional PCB alignment usually only operates in a single direction, while the alignment mechanism of this embodiment significantly improves the stacking accuracy by working simultaneously in two perpendicular directions, which can reduce the adjustment time in subsequent processes and improve the overall production efficiency.

[0038] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the alignment mechanism further includes a first driving component, which is mounted on the frame 1 and connected to the first alignment component 2. The first driving component can drive the first alignment component 2 to reciprocate along a first direction. In this embodiment, the first driving component provides a precise and stable power source for the first alignment component 2. Compared to manual driving, this ensures that the force, stroke, and speed parameters of each alignment action remain highly consistent, greatly improving the repeatability and reliability of alignment. This effectively avoids fluctuations in alignment accuracy caused by differences in manual operation, enabling stacked boards (such as PCBs) to achieve stable and high-precision alignment effects in different batch production processes, which is beneficial to ensuring the consistency of product quality.

[0039] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the number of first alignment components 2 is at least two, and the output ends of the at least two first alignment components 2 are arranged sequentially along a first direction. A first driving component is connected to the at least two first alignment components 2, and the first driving component can drive the at least two first alignment components to reciprocate along the first direction. In this embodiment, the first driving component can drive the two first alignment components 2 to move in the same or opposite directions, so that the receiving area 4 can simultaneously place at least two stacks of boards, and the two first alignment components 2 can simultaneously align the two stacks of boards to both sides, improving processing efficiency and significantly reducing processing time.

[0040] In one embodiment, the first driving assembly includes at least two driving elements 5, which are mounted on the frame 1. Each first alignment assembly 2 is connected to one driving element 5, and the driving element 5 drives the first alignment assembly 2 to reciprocate along a first direction. In this embodiment, there are two first alignment assemblies 2 and two driving elements 5, with one first alignment assembly 2 connected to one driving element 5, achieving one-to-one control, improving processing efficiency, significantly reducing processing time, and ensuring the efficiency and accuracy of alignment.

[0041] Please see Figure 1 , Figure 2 and Figure 5In one embodiment, the driving component 5 includes a first power source 51, a first driving wheel 52, a first driven wheel 53, and a first transmission belt 54. The housing of the first power source 51 is mounted on the frame 1. The first driving wheel 52 is mounted on the output end of the first power source 51. The first driving wheel 52 and the first driven wheel 53 are arranged at intervals along a first direction. The first transmission belt 54 is wound around the outer circumferential surfaces of the first driving wheel 52 and the first driven wheel 53. The first alignment assembly 2 is connected to the first transmission belt 54. In this embodiment, the first power source 51 is a motor. The first power source 51 provides stable power output for the entire driving process. The interval arrangement of the first driving wheel 52 and the first driven wheel 53, as well as the winding of the first transmission belt 54, can convert the rotational motion of the power source into the linear motion of the first transmission belt 54, thereby driving the first alignment assembly 2 to move along the first direction. This transmission method has the advantages of relatively simple structure and low cost, and can control the movement speed and displacement of the first alignment component 2 more accurately, ensuring that the force is uniform and stable when aligning boards (such as PCBs), which helps to improve the accuracy and consistency of alignment and reduce the alignment deviation of boards caused by unstable power transmission.

[0042] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment, the alignment mechanism further includes a first slide rail plate 7, which is disposed on the frame 1 and extends along a first direction. The first alignment component 2 is slidably connected to the first slide rail plate 7. In this embodiment, the first slide rail plate 7 is provided with two parallel tracks, and the first alignment component 2 is slidably connected to the two tracks. The configuration of the first slide rail plate 7 provides stable guidance and support for the first alignment component 2, further improving the accuracy of the alignment action and effectively extending the service life of the first alignment component 2.

[0043] Please see Figure 1 and Figure 5In one embodiment, the first alignment component 2 includes a first fixing block 21, a connecting plate 22, and a first alignment member 23 connected in sequence. The first fixing block 21 is connected to the first driving component, the connecting plate 22 is slidably connected to the first slide rail 7, and the end of the first alignment member 23 facing away from the connecting plate 22 extends into the receiving area 4. In this embodiment, the first alignment member 23 includes a first striking rod and a first striking block. One end of the first striking rod is connected to the connecting plate 22, and the bottom of the other end of the first striking rod is provided with a first striking block. The first striking block is used to align multiple stacked plates along a first direction. The first fixing block 21 is connected to the first conveyor belt 54. The direct connection of the first fixing block 21 to the first conveyor belt 54 ensures that the power transmitted by the power source through the conveyor belt can be efficiently transmitted to the first alignment component 2, improving the response speed and accuracy of the alignment action. The sliding connection of the connecting plate 22 provides stable guidance, ensuring the straightness of the alignment component when moving along the first direction, and improving the alignment accuracy.

[0044] In one embodiment, the alignment mechanism further includes a second driving component 6, which is mounted on the frame 1 and connected to the second alignment component 3. The second driving component 6 drives the second alignment component 3 to reciprocate along a second direction. In this embodiment, the second driving component 6 provides a precise and stable power source for the second alignment component 3. Compared to manual driving, this ensures that the force, stroke, and speed parameters of each alignment action remain highly consistent, greatly improving the repeatability and reliability of alignment. This effectively avoids fluctuations in alignment accuracy caused by differences in manual operation, enabling stacked boards (such as PCBs) to achieve stable and high-precision alignment effects in different batch production processes, which is beneficial for ensuring product quality consistency.

[0045] Please see Figure 1 and Figure 6 In one embodiment, the second drive assembly 6 includes a second power source 61, a second driving wheel 62, a second driven wheel 63, and a second transmission belt 64. The housing of the second power source 61 is mounted on the frame 1. The second driving wheel 62 is mounted on the output end of the second power source 61. The second driving wheel 62 and the second driven wheel 63 are arranged at intervals along a second direction. The second transmission belt 64 is wound around the outer circumferential surfaces of the second driving wheel 62 and the second driven wheel 63. The second alignment assembly 3 is connected to the second transmission belt 64. In one embodiment, the second power source 61 is a motor. The second power source 61 provides a stable power output, enabling the second alignment assembly 3 to perform alignment work efficiently. The connection between the second fixing block 31 and the transmission belt provides a stable force transmission path, enhancing the stability and reliability of the entire alignment assembly during operation.

[0046] Please see Figure 1 and Figure 4In one embodiment, the second drive assembly 6 further includes a synchronous transmission member 9 and a synchronous conveying member 8. The frame 1 has a first side and a second side opposite to each other along the first direction. The second driving wheel 62 and the second driven wheel 63 are arranged on the first side of the frame 1, and the synchronous conveying member 8 is arranged on the second side of the frame 1. The synchronous transmission member 9 is connected between the output end of the second power source 61 and the synchronous conveying member 8.

[0047] The synchronous conveyor 8 extends along the second direction. One end of the second alignment component 3 is connected to the second conveyor belt 64, and the other end of the second alignment component 3 is connected to the synchronous conveyor 8. The second power source 61 drives one end of the second alignment component 3 to reciprocate along the second direction via the second conveyor belt 64, and the second power source 61 drives the other end of the second alignment component 3 to reciprocate along the second direction via the synchronous conveyor 8. In this embodiment, the second power source 61 and the synchronous conveyor 8 are connected by the synchronous transmission component 9, ensuring that the power in the second direction can be applied simultaneously and evenly to both ends of the second alignment component 3. This synchronous drive mechanism effectively avoids problems such as uneven force and torsion deformation that may occur when the second alignment component 3 is driven from only one end, allowing the second alignment component 3 to maintain a stable motion state throughout the entire stroke, thereby greatly improving the accuracy and consistency of alignment of boards (such as PCBs).

[0048] Please see Figure 3 In one embodiment, the synchronous conveyor 8 includes a third driven wheel 81, a fourth driven wheel 82 and a third conveyor belt 83. The third driven wheel 81 and the fourth driven wheel 82 are arranged at intervals along the second direction on the second side of the frame 1, and the third conveyor belt 83 is wrapped around the outer peripheral surface of the third driven wheel 81 and the outer peripheral surface of the fourth driven wheel 82.

[0049] Synchronous transmission component 9 is connected between the output end of the second power source 61 and the third driven wheel 81. The second power source 61 drives the third transmission belt 83 to reciprocate along the second direction through the synchronous transmission component 9. One end of the second alignment component 3 is connected to the second transmission belt 64, and the other end of the second alignment component 3 is connected to the third transmission belt 83. In this embodiment, through the synchronous conveying component 8 composed of the third driven wheel 81, the fourth driven wheel 82, and the third transmission belt 83, combined with the connection design between the synchronous transmission component 9 and the second power source 61, power can be simultaneously transmitted from the second power source 61 to the second transmission belt 64 and the third transmission belt 83, thereby acting on both ends of the second alignment component 3. This multi-link power transmission method ensures that both ends of the second alignment component 3 can obtain synchronous and uniform driving force in the second direction, avoiding the situation where one end is subjected to greater force and the other end to less force due to uneven power. This allows the second alignment component 3 to maintain a stable and straight motion state throughout the entire reciprocating movement, significantly improving the accuracy of aligning the plates.

[0050] Please see Figures 1 to 3 In one embodiment, the synchronous transmission component 9 includes a first synchronous pulley 91, a second synchronous pulley 92, a synchronous transmission belt 93, a transmission shaft 94, and a bearing seat 95. The first synchronous pulley 91 is located at the output end of the second power source 61, the bearing seat 95 is located on the second side of the frame 1, and the transmission shaft 94 is rotatably mounted in the inner hole of the bearing seat 95. A third driven pulley 81 is fixedly mounted on one end of the transmission shaft 94, the second synchronous pulley 92 is fixedly mounted on the other end of the transmission shaft 94, and the synchronous transmission belt 93 is wound around the outer circumferential surfaces of the first synchronous pulley 91 and the second synchronous pulley 92. In this embodiment, the bearing seat 95 provides stable support for the transmission shaft 94. The rotation of the transmission shaft 94 in the inner hole of the bearing seat 95 effectively reduces the shaking and offset of the transmission shaft 94 during power transmission. Through the first synchronous pulley 91, the second synchronous pulley 92, and the synchronous transmission belt 93 between them, precise synchronous transmission can be achieved, making power transmission more stable when driving the second alignment component 3 to perform alignment operations.

[0051] Please see Figure 2 and Figure 6 In one embodiment, the alignment mechanism further includes a second slide rail plate 10, which is disposed on the frame 1 and extends along a second direction. The second alignment component 3 is slidably connected to the second slide rail plate 10. In this embodiment, the first and second sides of the frame 1 are both provided with the second slide rail plate 10, and both ends of the second alignment component 3 are slidably connected to the second slide rail plate 10. The second slide rail plate 10 provides stable guidance and support for the second alignment component 3, further improving the accuracy of the alignment action and effectively extending the service life of the second alignment component 3.

[0052] Please see Figure 6 In one embodiment, the second alignment assembly 3 includes a second fixing block 31, a sliding seat 32, and a second alignment member 33 connected in sequence. The second fixing block 31 is connected to the second driving assembly 6, the sliding seat 32 is slidably connected to the second slide rail plate 10, and the second alignment member 33 extends into the receiving area 4. In this embodiment, the second alignment member 33 includes a second striking arm 331 and a plurality of second striking blocks 332 mounted on the bottom of the second striking arm 331. The second striking arm 331 is connected to the sliding seat 32. When the second striking arm 331 reciprocates along a second direction, the second striking blocks 332 can align the board (e.g., PCB). The design of the second fixing block 31 being connected to the second driving assembly 6 and the sliding seat 32 being slidably connected to the second slide rail plate 10 allows the second alignment assembly 3 to perform reciprocating motion efficiently, thereby improving the efficiency of the alignment work. The sliding connection between the sliding seat 32 and the second slide rail plate 10 provides stable guidance and extends the service life of the alignment assembly.

[0053] In one embodiment, two sensors and a sensing plate are disposed below each first aligning member 23 to set the origin and movement limits of the first aligning member 23. Two sensors and a sensing plate are also disposed below the second aligning member 33 to set the origin and movement limits of the second aligning member 33. In this embodiment, by using two sensors and a sensing plate, the starting position (origin) of the aligning member can be accurately determined, ensuring the accuracy of the aligning action and preventing the aligning member from exceeding the predetermined range during movement, thus avoiding possible mechanical collisions or damage.

[0054] Please see Figure 2 In one embodiment, an idler seat 11 is provided on the frame 1, and an idler wheel 12 is provided in the idler seat 11 for tensioning the synchronous transmission belt 93. In this embodiment, the synchronous transmission belt 93 is tensioned by the idler wheel 12 to maintain appropriate tension, ensure good contact between the synchronous belt and the synchronous wheel, prevent the synchronous belt from slipping or slipping during transmission, and improve transmission efficiency and reliability.

[0055] According to the alignment mechanism of this utility model embodiment, after multiple stacked boards (such as PCBs) are placed in the receiving area 4 of the rack 1, the first alignment component 2 operates to push some or all of the boards in the receiving area 4 along the first direction. Through this pushing action, the boards achieve initial alignment in the first direction, eliminating positional deviations in that direction. The second alignment component 3 operates to push the boards along the second direction intersecting the first direction, further adjusting the position of the boards in the second direction, ensuring that the boards are accurately aligned in both intersecting directions. Thus, through the coordinated action of the first alignment component 2 and the second alignment component 3 in different directions, multi-directional accurate alignment of the stacked boards is achieved. Traditional loading tables typically align stacked PCBs only in a single direction, which makes it impossible to effectively correct positional deviations of the PCBs in another dimension, resulting in low stacking accuracy. However, this alignment mechanism, by setting the first alignment component 2 and the second alignment component 3 in the intersecting first and second directions, can achieve multi-directional accurate alignment of stacked PCBs in the XY plane. This not only improves the neatness and precision of PCB stacking, reducing errors and defect rates in subsequent inspection and processing due to inaccurate alignment, but also enhances the automation and production efficiency of the entire PCB production process, reduces labor costs and quality risks caused by human error, and helps promote the development of the PCB manufacturing industry towards a high-precision and high-efficiency production model.

[0056] In addition, one embodiment of this utility model provides a feeding device for PCB feeding, including the alignment mechanism described in the above embodiment. In this embodiment, the feeding device further includes a waiting platform, a waiting platform conveying device, a lifting platform, and a lifting platform driving device. Multiple stacked PCBs are placed on the waiting platform. The waiting platform conveying device moves the waiting platform in the front-back direction and transports the multiple stacked PCBs to the lifting platform. The lifting platform driving device drives the lifting platform to move upward, so that the multiple stacked PCBs move to the receiving area 4. The lifting platform can be provided with a limiting structure that cooperates with the first alignment component 2 and the second alignment component 3. The first alignment component 2, the second alignment component 3, and the limiting structure align the multiple stacked PCBs in the front-back direction and the left-right direction, improving the neatness and accuracy of PCB stacking and reducing errors and defect rates in subsequent inspection and processing due to inaccurate alignment.

[0057] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
