[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] like Figures 1 to 4 As shown, one embodiment of this application provides a fixing mechanism, including a positioning platform 1 and a plurality of positioning components 2. The positioning platform 1 has a first side and a second side opposite to each other along a first direction, and positioning components 2 are provided on both the first side and the second side.

[0036] The positioning component 2 includes a connecting frame 21, a power component 22, and a positioning component 23. The positioning platform 1 is provided with a bearing station, which is located between the connecting frame 21 on the first side and the second side.

[0037] The power component 22 and the positioning component 23 are mounted on the connecting frame 21. The positioning component 23 is connected to the output end of the power component 22, and the power component 22 drives the positioning component 23 to reciprocate along the second direction. The connecting frame on the first side can reciprocate along the first direction, and / or the connecting frame 21 on the second side can reciprocate along the first direction, so that the positioning platform 1 and the corresponding positioning component 23 can be clamped on opposite sides of the circuit board 3 on the bearing station along the first direction; wherein, the first direction and the second direction intersect. In this embodiment, the first direction is the front-back direction, and the second direction is the up-down direction; or, the first direction is the upper-lower direction. Figure 1 The X direction in the middle, the second direction is attached. Figure 1 The Z-direction is described. Traditional fixing mechanisms are adapted to a single specification, while at least one of the first and second side connecting frames 21 of the fixing mechanism in this application can reciprocate along the first direction. This allows for flexible adjustment of the spacing according to the size of the circuit board 3 in the first direction, adapting to both small wearable device circuit boards and large server motherboards. This significantly reduces the cost for companies to purchase multiple fixing devices for different specifications of circuit boards 3, meeting the needs of small-batch, multi-variety production. Simultaneously, the power component 22 drives the positioning component 23 to reciprocate along the second direction, achieving bidirectional precise clamping of the circuit board 3. After size adaptation is completed in the first direction, the clamping action in the second direction ensures the stability of the circuit board 3 during high-precision processing such as inkjet printing and drilling, avoiding positional deviations caused by unstable fixing, minimizing processing errors, and improving product yield. It is understood that the specific structure of the power component 22 is not limited in this application embodiment; the power component 22 can be a cylinder, motor-screw, or gear rack structure, etc. Furthermore, this embodiment does not limit the way the positioning component 2 is moved. It can be driven by a device such as a motor-screw, cylinder, or motor-belt, or it can be driven by human power or other means.

[0038] In one embodiment, the positioning stage 1 has a third side and a fourth side opposite to each other along a third direction, and positioning components 2 are provided on both the third side and the fourth side. The bearing station is located between the positioning components 2 on the third side and the fourth side.

[0039] At least one of the connecting frames 21 on the third and fourth sides can reciprocate along a third direction, so that the positioning platform 1 and the corresponding positioning member 23 can clamp the circuit board 3 on the bearing station on opposite sides along the third direction; wherein, the first direction, the second direction, and the third direction intersect each other and are not coplanar. In this embodiment, the third direction is the left-right direction; or, the third direction is the auxiliary direction. Figure 1The positioning components 2 in the three directions can be easily adjusted by the operator according to the actual size and shape of the circuit board 3, without the need to replace the fixing mechanism or make complex settings. This greatly simplifies the production process, improves the flexibility and efficiency of the production line, and reduces production delays and scrap rates caused by improper fixing. At the same time, because the fixing mechanism can be adjusted in three directions, it can adapt to more types and shapes of circuit boards 3. Whether it is a rectangular, square, or other irregularly shaped circuit board 3, precise fixing can be achieved by adjusting the positioning components 2 in three directions, making this fixing mechanism widely applicable in various circuit board 3 production scenarios.

[0040] like Figure 2 As shown, in one embodiment, the positioning member 23 includes a mounting base 231 and a plurality of positioning blocks 232, the plurality of positioning blocks 232 being arranged at intervals between each other on the mounting base 231;

[0041] Mounting base 231 is movably connected to connecting frame 21, and mounting base 231 is connected to the output end of power component 22. In this embodiment, one power component 22 drives multiple positioning blocks 232 to move synchronously along the second direction, which can clamp and fix the circuit board 3 from multiple points. Compared with a single positioning block 232, multi-point clamping can more evenly distribute the fixing pressure, effectively preventing the circuit board 3 from twisting, deforming or locally warping during processing. When performing high-precision drilling, milling or inkjet printing processes, the stable state of the circuit board 3 can ensure the accuracy of the processing position, greatly reduce the scrap rate caused by unstable fixing, and improve product quality.

[0042] like Figure 2As shown, in one embodiment, the mounting base 231 includes a base plate 2311 and multiple side plates 2312. The base plate 2311 is connected to the output end of the power component 22. The multiple side plates 2312 are arranged at intervals along a second direction on the same side of the base plate 2311. All the side plates 2312 are connected to the base plate 2311 respectively. A positioning block 232 is connected to the end of the side plate 2312 facing away from the base plate 2311. In this embodiment, the base plate 2311 is connected to the output end of the power component 22, serving as the basic load-bearing component of the entire mounting base 231 and providing a stable power transmission path. The multiple side plates 2312 are arranged along the second direction on the same side of the base plate 2311, forming a frame-like structure with the base plate 2311, which enhances the overall rigidity and deformation resistance of the mounting base 231. When the power component 22 drives the positioning block 232 to reciprocate, it effectively reduces the shaking or displacement of the mounting base 231 itself, ensuring that the positioning block 232 always accurately clamps and positions the circuit board 3, thus improving the reliability of the fixing effect. Simultaneously, the multiple side plates 2312 are spaced apart, allowing for flexible adjustment of the positioning block 232's installation position according to the different shapes and sizes of the circuit board 3. For irregularly shaped circuit boards 3, the positioning block 232 can be installed at key stress points or edges for targeted and stable clamping; for conventional rectangular circuit boards 3, the positioning blocks 232 can be rationally distributed to evenly distribute the clamping force around the circuit board 3, preventing excessive localized force from damaging the circuit board 3 and improving the adaptability of the fixing mechanism to various types of circuit boards 3.

[0043] In one embodiment, the positioning block 232 and the mounting base 231 are detachably connected. In this embodiment, the positioning block 232 can be quickly replaced according to different needs (such as adjusting the size, shape, or clamping surface structure of the positioning block 232), without the need to replace the entire positioning assembly 2 or adjust the power system. This significantly enhances the adaptability of the fixing mechanism to diverse circuit boards 3 and reduces equipment idleness caused by specification limitations. It is understood that the positioning rib and the mounting base 231 can be snap-fitted, or the positioning rib and the mounting base 231 can be connected together by external fasteners.

[0044] like Figure 4As shown, in one embodiment, the positioning block 232 has a first mounting hole 2321, and the mounting base 231 has a second mounting hole 2313. The first mounting hole 2321 and the second mounting hole 2313 are interconnected. Fasteners are suitable for inserting into the first mounting hole 2321 and the second mounting hole 2313 to fix the positioning block 232 onto the mounting base 231. It is understood that the fasteners can be inserted into the first mounting hole 2321 and the second mounting hole 2313, or they can be threaded into the first mounting hole 2321 and the second mounting hole 2313. In this embodiment, the connection or separation of the positioning block 232 and the mounting base 231 can be quickly completed by installing and removing the fasteners in the first and second mounting holes. When replacing positioning blocks 232 of different specifications to fit circuit boards 3 of different sizes, operators do not need complicated tools and cumbersome procedures. They can quickly complete the replacement of positioning blocks 232 by simply tightening or loosening the fasteners, which greatly shortens the equipment adjustment time, improves the changeover efficiency of the production line, and meets the needs of multi-variety, small-batch production.

[0045] like Figure 4 As shown, in one embodiment, the first mounting hole 2321 penetrates the positioning block 232 along the second direction;

[0046] And / or, the second mounting hole 2313 is a through hole or a blind hole. In this embodiment, the through hole design eliminates the need to distinguish between the "positive and negative directions" when installing the positioning block 232. Fasteners can be inserted simply by ensuring that the first mounting hole 2321 is aligned with the second mounting hole 2313 of the mounting base 231. This avoids rework problems caused by incorrect installation direction, making it particularly suitable for scenarios requiring frequent replacement of the positioning block 232 and further shortening equipment adjustment time.

[0047] like Figure 4 As shown, in one embodiment, the fastener is a threaded fastener, and both the first mounting hole 2321 and the second mounting hole 2313 are threaded holes. In this embodiment, the threaded fastener is a screw, and the tightness between the positioning block 232 and the mounting base 231 can be easily adjusted by controlling the tightening degree of the screw. For circuit boards 3 of different materials and thicknesses, the screw tightening force can be adjusted appropriately to ensure the fixing effect while avoiding damage to the circuit board 3 due to excessive clamping force or insecure fixing due to insufficient clamping force. In addition, if it is necessary to fine-tune the position of the positioning block 232 later, it can also be easily achieved by tightening the screw, meeting diverse production needs. In other embodiments, the threaded fastener is a bolt-nut structure.

[0048] like Figure 4As shown, in one embodiment, the first mounting hole 2321 includes a connecting hole 23211 and a receiving hole 23212. The connecting hole 23211 communicates between the receiving hole 23212 and the second mounting hole 2313. The shank of the threaded fastener is threadedly connected to both the connecting hole 23211 and the second mounting hole 2313, and the head of the threaded fastener is located in the receiving hole 23212. In this embodiment, by hiding the head of the threaded fastener in the receiving hole 23212, it does not interfere with other surrounding components or structures, providing greater flexibility for the layout of other components inside the equipment, facilitating a more rational arrangement of the positions of various components, and improving the integration and compactness of the equipment. At the same time, the receiving hole 23212 can provide a certain degree of protection for the head of the threaded fastener, preventing it from being directly impacted, scratched, or corroded by the external environment, ensuring the reliability of the installation.

[0049] In one embodiment, the positioning block 232 is snapped into the mounting base 231. In this embodiment, the positioning block 232 has a buckle, and the mounting base 231 has a slot; the buckle snaps into the slot. In other embodiments, the mounting base 231 has a buckle, and the positioning block 232 has a slot. The snap-fit ​​method is simple to operate; simply align the buckle on the positioning block 232 with the slot on the mounting base 231 and apply a certain amount of pressure to complete the installation. No additional tools are required, greatly shortening the installation time and improving production efficiency.

[0050] like Figures 1-3As shown, in one embodiment, the fixing mechanism further includes a drive component 4, which is arranged on the positioning table 1. The connecting frame 21 is connected to the output end of the drive component 4. The drive component 4 is used to drive at least one of the connecting frames 21 on the first and second sides to reciprocate along a first direction. In this embodiment, the introduction of the drive component 4 enables the positioning component 2 to automatically perform position adjustment, positioning, and other actions without manual operation, greatly improving production efficiency and operational accuracy. For example, on an automated production line, through the control of the drive component 4, the positioning component 2 can quickly and accurately position the workpiece to a designated position, achieving continuous and efficient production operations. At the same time, the drive component 4 typically has high motion accuracy and controllability, and can accurately control the motion trajectory and position of the positioning component 2, thereby achieving high-precision positioning. It is understood that the specific structure of the drive component 4 is not limited in the embodiments of this application. The drive component 4 can be a cylinder, a motor-screw, a motor-belt, or a gear and rack structure. For example, when the drive component 4 is a cylinder, the cylinder body is arranged on the positioning table 1, and the output end of the cylinder is connected to the connecting frame 21. When the drive assembly 4 is a motor-screw type, the motor is positioned on the positioning table 1, and the connecting frame 21 is threadedly connected to the screw. The screw is connected to the output end of the motor, allowing the rotation of the motor to be converted into linear motion of the positioning assembly 2. When the drive assembly 4 is a motor-conveyor belt type, the motor is positioned on the positioning table 1, with a drive wheel on the motor's output shaft. The positioning table 1 also has driven wheels spaced apart from the drive wheels. A synchronous belt is wound around the drive and driven wheels, and the connecting frame 21 is connected to the synchronous belt, thereby driving the positioning assembly 2 to move linearly. Alternatively, the connecting frame 21 may not be connected to the synchronous belt. The driven wheel is sleeved on a lead screw, which is threadedly connected to the connecting frame 21. The rotation of the motor causes the lead screw to rotate, thus achieving linear motion of the positioning assembly 2.

[0051] like Figure 1As shown, in one embodiment, a first limiting groove 5 is provided on the first side, and a second limiting groove 6 is provided on the second side. The connecting frame 21 on the first side is located in the first limiting groove 5 and can reciprocate along the first direction. The connecting frame 21 on the second side is located in the second limiting groove 6 and can reciprocate along the first direction. In this embodiment, the first limiting groove 5 and the second limiting groove 6 provide a clear movement track for the connecting frame 21, allowing it to reciprocate only along the first direction. This effectively avoids unexpected movements such as offset, swaying, or rotation of the connecting frame 21 during movement, ensuring the accuracy and straightness of the connecting frame 21's movement. Simultaneously, the dimension of the first limiting groove 5 in the first direction is larger than the dimension of the second limiting groove 6 in the first direction. Using the side of the circuit board 3 facing the second side as a positioning reference, when the circuit board 3 is placed in the bearing station, the second side can quickly and accurately find its required position, laying a good foundation for subsequent positioning operations and effectively reducing positioning errors. Furthermore, the dimensions of circuit boards 3 of different specifications may differ in the first direction. The larger first limiting groove 5 allows the first side positioning component 2 to adapt to the positioning requirements of circuit boards 3 of different sizes. By moving the first side positioning component 2, the distance between it and the second side positioning component 2 can be adjusted, thereby effectively clamping and positioning circuit boards 3 of different sizes, improving the versatility of the bearing station for different circuit boards 3, and reducing the cost of replacing positioning fixtures or equipment due to changes in the size of the circuit board 3.

[0052] like Figure 1 As shown, in one embodiment, a third limiting groove 7 is provided on the third side, and a fourth limiting groove 8 is provided on the fourth side. The connecting frame 21 on the third side is located in the third limiting groove 7 and can reciprocate along the third direction. The connecting frame 21 on the fourth side is located in the fourth limiting groove 8 and can reciprocate along the third direction. In this embodiment, the third limiting groove 7 and the fourth limiting groove 8 provide a clear movement track for the connecting frame 21, allowing it to reciprocate only along the third direction. This effectively avoids unexpected movements such as offset, swaying, or rotation of the connecting frame 21 during movement, ensuring the accuracy and straightness of the movement of the connecting frame 21.

[0053] According to the fixing mechanism of this application embodiment, during operation, the circuit board 3 is first placed on the bearing position of the positioning table 1. Since the positioning table 1 is provided with positioning components 2 on both the first and second sides, and the connecting frame 21 on at least one side can reciprocate along the first direction, the position of the connecting frame 21 can be adjusted according to the size of the circuit board 3 along the first direction to initially adapt to the size of the circuit board 3 in the first direction. Then, the power component 22 on the connecting frame 21 starts to work, driving the positioning component 23 connected to it to reciprocate along the second direction. The positioning components 23 on both sides of the positioning table 1 in the first direction move towards the circuit board 3, and the circuit board 3 is clamped on the bearing position by the positioning component 23 or the clamping plate, thereby achieving precise fixing of circuit boards 3 of different sizes and shapes, ensuring that the circuit board 3 remains stable and without displacement during subsequent inkjet printing, drilling and other processing. This application can achieve effective fixing of circuit boards 3 of different sizes and shapes by means of the adjustable connecting frame 21 and the positioning component 23 driven by the power component 22. This greatly improves the flexibility and efficiency of the production line and reduces the cost and time required to replace the fixing mechanism when changing the circuit board specification 3.

[0054] This application provides a processing apparatus, including a processing body and a fixing mechanism as described in the above embodiment. The processing body is used to process the circuit board 3 on the support station. In this embodiment, before processing the circuit board 3 on the support station, the positioning member 23 driven by the adjustable connecting frame 21 and the power member 22 can effectively fix the circuit boards 3 of different sizes and shapes. This greatly improves the flexibility and efficiency of the production line and reduces the cost and time required to replace the fixing mechanism when changing the specifications of the circuit board 3.

[0055] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
