DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.

[0036] As shown in Figures 1 to 3 An embodiment of the utility model provides a material moving assembly 100 for transferring PCB, the PCB has a pin, the material moving assembly 100 includes a clamping plate 1 and a positioning seat 2, the top of the positioning seat 2 has a bearing surface 3, the positioning seat 2 is equipped with a limiting groove 4, the pin can extend into the limiting groove 4;

[0037] The limiting groove 4 has a first groove wall 41 opposite to the clamping plate 1 along a first direction;

[0038] The clamping plate 1 can move along the first direction to push the PCB to move, so that one end of the PCB can abut against the clamping plate 1 and the first groove wall 41 abuts against the pin. In the embodiment, the material moving assembly 100 adopts a single clamping plate 1 and positioning seat 2 design, compared with the traditional double clamping plate 1 structure, greatly simplifies the structure of the assembly, which not only reduces the number of parts, but also avoids the use of complex components such as springs, limiting devices, thereby reducing the manufacturing cost and the complexity of the assembly. Through the limiting groove 4 provided on the positioning seat 2, the pin on the PCB can be accurately aligned, ensuring the positioning accuracy of the PCB during clamping. The clamping plate 1 moves along the first direction and directly abuts against the PCB and pushes it until the pin abuts against the first groove wall 41 of the limiting groove 4, which is fast and accurate, improving the production efficiency. The design of the clamping plate 1 allows it to abut against the side of the PCB with moderate force, and the first groove wall 41 abuts against the pin on the PCB, reducing the risk of damaging the PCB during clamping.

[0039] In an embodiment, the material moving assembly 100 further includes a driving member 5, the driving member 5 is arranged on the positioning seat 2, and the driving member 5 is connected with the clamping plate 1;

[0040] The driving member 5 is arranged to extend along a second direction, and the driving member 5 is capable of driving the clamping plate 1 to move along a first direction, the first direction being perpendicular to the second direction. In the embodiment, the first direction is the X direction, and the second direction is the Y direction. When the driving member 5 is activated, it transmits power to the clamping plate 1, so that the clamping plate 1 moves to a position in contact with the PCB. The movement of the clamping plate 1 ensures that the pins on the PCB are in abutment with the first slot wall 41 of the limiting slot 4, thereby achieving firm clamping. By precisely controlling the power output of the driving member 5, the movement distance and speed of the clamping plate 1 can be adjusted to adapt to PCBs of different sizes and shapes, ensuring the flexibility and accuracy of the clamping process. Compared with the complex double-clamping plate 1 structure, this design reduces the number of components and maintenance costs, and also reduces the skill requirements for operators due to the simple operation. At the same time, since the movement of the clamping plate 1 is precisely controlled by the driving member 5, the stability during the clamping process can be ensured, and the damage to the PCB caused by improper operation can be reduced.

[0041] In an embodiment, the material moving assembly 100 further comprises a slide rail 6 arranged on the positioning seat 2 and extending along the first direction, and the clamping plate 1 is slidingly connected to the slide rail 6. When the driving member 5 starts to work, it generates a driving force, which is transmitted to the clamping plate 1 through some transmission mechanism (such as a connecting rod, a gear, etc., depending on the type and design of the driving member 5). After being subjected to the driving force, the clamping plate 1 starts to move along the slide rail 6. Due to the presence of the slide rail 6, the movement path of the clamping plate 1 is precisely defined, thereby ensuring the stability and accuracy of the clamping process.

[0042] In an embodiment, the slide rail 6 is provided with at least two slide rails 6 arranged at intervals along the second direction; and the limiting slot 4 is arranged between the adjacent two slide rails 6. In the embodiment, the first direction is the X direction, and the second direction is the Y direction. The arrangement of at least two slide rails 6 at intervals along the second direction provides guidance and support for the movement of the clamping plate 1, increases the stability of the material moving assembly 100, reduces the shaking or deviation during the clamping process, and thereby improves the accuracy of the clamping.

In this embodiment, through the design of the conversion member 52, the clamping plate 1 can move along a different direction (i.e. the first direction) when the power member 51 moves along the second direction, and the moving direction of the power member 51 can be conveniently converted into the required direction, so as to meet the specific operation requirements. Since the moving directions of the power member 51 and the clamping plate 1 are perpendicular to each other, more complex operations can be realized in a limited space, which helps to save space and improve the compactness of the equipment.

The power member 51 is connected with the first sliding block, and when the power member 51 is activated, it drives the first sliding block to move along the second direction. The guide member 523 is connected with the first sliding block and slidingly connected with the guide groove 5221 on the second sliding block 522. This design allows the guide member 523 to slide along the guide groove 5221 when the first sliding block moves, and since the guide member 523 is connected with the second sliding block 522, the movement of the guide member 523 drives the second sliding block 522 and the clamping plate 1 to move along the first direction, thereby realizing clamping or releasing of the PCB and improving clamping accuracy.

In this embodiment, the guide groove 5221 is arranged obliquely on the second sliding block, and the first direction and the second direction form an angle with the extension direction of the guide groove 5221. The oblique arrangement of the guide groove 5221 can accurately control the movement of the clamping plate 1 through the structure of the sliding block and the guide member 523, improve clamping accuracy, and ensure accurate positioning of the PCB during processing, which can adapt to PCBs of different sizes and shapes and increase the flexibility and application range of the material moving assembly 100.

[0047] In an embodiment, the power element 51 is a cylinder arranged along the second direction on the positioning seat 2, and the conversion element 52 is connected to the output end of the cylinder. In this embodiment, by arranging the cylinder along the second direction, the extension and retraction action of the cylinder is performed in the direction perpendicular to the movement direction of the clamping plate 1, so that the occupation of the overall space by the cylinder action is minimized, and the device layout is more compact. This layout can effectively save space and reduce the floor area occupied by the device.

Through the design of the limiting slot 4 and the clamping plate 1, the surface of the PCB can be prevented from being damaged, and meanwhile, the stable clamping and positioning of the PCB are realized through the simple structure (including the clamping plate 1, the positioning seat 2 and the bearing surface 3), the number of components is reduced, and the manufacturing cost is reduced.
