The positioning component includes a mounting plate that slides with the worktable and an alignment component that slides with the mounting plate. The sliding direction of the mounting plate is the same as the sliding direction of the alignment component. The driving component can drive the mounting plate to slide, and the alignment component can passively slide under the action of the ceramic circuit board. In this ceramic circuit board center positioning mechanism to prevent magnetic cracking, the driving component drives the mounting plate to move, thereby the alignment component abuts against the ceramic circuit board to push the ceramic circuit board to a preset position, facilitating its subsequent transport to the next process.

Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, specifically relating to a center positioning mechanism for ceramic circuit boards that prevents magnetic cracking. Background Technology

[0002] Ceramic circuit boards are electronic component carriers that use ceramic materials as substrates. They possess excellent thermal conductivity, insulation, and high-temperature stability, and are widely used in medical, automotive electronics, communications, aerospace, and power module fields. During the transport of ceramic circuit boards, a positioning mechanism is required to align them to ensure they are in a position that can be attracted, thus facilitating their transport to the next process. However, pushing the ceramic circuit board to its corresponding position using the positioning mechanism may pose a risk of magnetic cracking due to excessive pushing force.

[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a ceramic circuit board center positioning mechanism to prevent magnetic cracking. Utility Model Content

[0004] The purpose of this invention is to provide a ceramic circuit board center positioning mechanism to prevent magnetic cracking, which can solve the problem that the ceramic circuit board may crack due to excessive thrust of the positioning mechanism during positioning.

[0005] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows: A ceramic circuit board center positioning mechanism for preventing magnetic cracking includes a worktable, a positioning component mounted on the worktable, and a driving component. The positioning component includes a mounting plate that slides with the worktable and an aligning component that slides with the mounting plate. The sliding direction of the mounting plate is the same as the sliding direction of the aligning component. The driving component can drive the mounting plate to slide, and the aligning component can passively slide under the action of the ceramic circuit board.

[0006] In one or more embodiments of this utility model, the ceramic circuit board center positioning mechanism further includes a positioning rod installed on the worktable, and a plurality of conveying rollers for conveying ceramic circuit boards are provided between the positioning rod and the positioning component. The driving component can drive the positioning component to move closer to or away from the positioning rod.

[0007] In one or more embodiments of the present invention, the positioning component further includes a connecting plate, the connecting plate being slidably connected to the mounting plate, the sliding direction of the connecting plate and the mounting plate being the same, and at least two of the positioning members being fixed on the connecting plate.

[0008] In one or more embodiments of the present invention, the positioning component further includes a limiting plate, the limiting plate being fixedly connected to the mounting plate, and at least two limiting plates are provided to abut against and restrict the connecting plate from detaching from the mounting plate.

[0009] In one or more embodiments of the present invention, the drive assembly includes a telescopic drive member, the telescopic drive member includes a telescopic shaft, and the telescopic shaft is fixedly connected to the mounting plate.

[0010] In one or more embodiments of this utility model, the ceramic circuit board center positioning mechanism includes two sets of positioning components arranged opposite to each other. The two sets of positioning components are respectively located on both sides of the positioning rod, and the positioning members of the two sets of positioning components slide towards or away from each other.

[0011] In one or more embodiments of the present invention, the driving component includes a telescopic driving member and a transmission member. The telescopic driving member includes a telescopic shaft, which is fixedly connected to the mounting plate of one of the positioning components. The transmission member drivesly connects the two positioning components.

[0012] In one or more embodiments of this utility model, the transmission component includes two driven wheels that respectively cooperate with the two positioning components, a belt is drivingly connected between the two driven wheels, and the mounting plates of the two positioning components are fixedly connected to the belt.

[0013] In one or more embodiments of this utility model, the positioning rod is provided with an abutting portion that can abut against the ceramic circuit board on the conveying roller; and / or, The positioning rod is provided with a clearance groove to avoid the conveyor roller.

[0014] In one or more embodiments of this utility model, the alignment member is located between the two conveying rollers.

[0015] Compared with existing technologies, the ceramic circuit board center positioning mechanism for preventing magnetic cracking of this utility model uses a drive assembly to move the mounting plate, thereby using a positioning component to abut against the ceramic circuit board and push it to a preset position for easy transport to the next process. Since the ceramic circuit board may have some dimensional errors, the positioning component can adaptively slide to retract a certain distance during positioning, effectively preventing excessive force from the positioning component clamping the ceramic circuit board and causing magnetic cracking.

[0019] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0020] Reference Figures 1 to 3 In one embodiment of this utility model, the ceramic circuit board center positioning mechanism for preventing magnetic cracking includes a worktable 1, a positioning component 2 mounted on the worktable 1, and a driving component 3.

[0021] Reference Figures 2 to 4 The positioning component 2 includes a mounting plate 21 that slides with the worktable 1 and an aligning component 22 that slides with the mounting plate 21. The sliding direction of the mounting plate 21 is the same as that of the aligning component 22. The driving component 3 can drive the mounting plate 21 to slide, and the aligning component 22 can slide passively under the action of the ceramic circuit board. The aligning component 22 can be a rod that abuts against the ceramic circuit board. All of the above sliding engagements can be achieved using slide rails and grooves.

[0022] Reference Figure 1 and Figure 2 The ceramic circuit board center positioning mechanism also includes a positioning rod 4 mounted on the worktable 1. Multiple conveying rollers 5 for transporting the ceramic circuit board are arranged between the positioning rod 4 and the positioning component 22. The drive assembly 3 can drive the positioning component 22 to move closer to or away from the positioning rod 4. The ceramic circuit board is visible. Figure 1 Mark a in the middle.

[0023] In this embodiment, multiple conveying rollers 5 are used to convey ceramic circuit boards into the next process. Parts of the positioning component 2 and the driving component 3 are both located in the space below the conveying rollers 5. The positioning rod 4 is provided with an abutment portion that can abut against the ceramic circuit board on the conveying roller 5, and the positioning rod 4 is provided with a clearance groove that can avoid the conveying roller 5. The positioning component 22 is located between two conveying rollers 5.

[0024] Therefore, during operation, the drive component 3 drives the mounting plate 21 to move, which in turn moves the positioning component 22. The positioning component 22 abuts against the ceramic circuit board, pushing it into contact with the abutment portion of the positioning rod 4, thus positioning it in a preset position for easy transport to the next process. For example, once the ceramic circuit board is in the preset position, the feeding structure can easily and accurately pick it up at that position. In this embodiment, the preset position is located on the surface of the conveying roller 5. Since the size of the ceramic circuit board may have some error, the positioning component 22 can adaptively slide to allow for a certain distance, effectively preventing the risk of magnetic cracking of the ceramic circuit board due to excessive clamping force.

[0025] Reference Figure 3 and Figure 4 The positioning component 2 also includes a connecting plate 23, which is slidably connected to the mounting plate 21. The sliding directions of the connecting plate 23 and the mounting plate 21 are the same, and at least two alignment members 22 are fixed on the connecting plate 23. In this embodiment, two alignment members 22 are fixed on the connecting plate 23 as an example for illustrative purposes. In other embodiments, the number of alignment members 22 can be adjusted, and this application does not impose any limitations on this. By setting two alignment members 22, the ceramic circuit board can be adjusted to a preset position more conveniently.

[0026] Reference Figure 3 and Figure 4 The positioning component 2 also includes a limiting plate 24, which is fixedly connected to the mounting plate 21. At least two limiting plates 24 are provided to abut and prevent the connecting plate 23 from detaching from the mounting plate 21. In this embodiment, the two limiting plates 24 are arranged along the sliding direction of the connecting plate 23. Specifically, a portion of the limiting plate 24 is connected to the mounting plate 21, while another portion can abut the beginning and end of the sliding direction of the connecting plate 23 to prevent it from detaching from the mounting plate 21.

[0027] Reference Figure 3 and Figure 4 In this embodiment, the drive assembly 3 includes a telescopic drive component 31, which includes a telescopic shaft fixedly connected to the mounting plate 21. Specifically, the telescopic drive component 31 can be a cylinder or a hydraulic cylinder, used to drive the mounting plate 21 to move, further driving the positioning component 22 to move, thereby adjusting the position of the ceramic circuit board.

[0028] Reference Figure 1 and Figure 2 The ceramic circuit board center positioning mechanism of this embodiment includes two sets of positioning components 2 arranged opposite to each other. The two sets of positioning components 2 are located on both sides of the positioning rod 4, and the alignment members 22 of the two sets of positioning components 2 slide towards or away from each other. The positions of the two sets of ceramic circuit boards can be adjusted simultaneously by the two sets of positioning components 2, thereby improving the processing efficiency of the ceramic circuit boards.

[0029] Reference Figure 3 and Figure 4 Based on this, the drive assembly 3 of this embodiment includes a telescopic drive component 31 and a transmission component. The telescopic drive component 31 includes a telescopic shaft, which is fixedly connected to the mounting plate 21 of one of the positioning components 2. The transmission component drives the two positioning components 2. Specifically, the transmission component includes two driven wheels 32 that respectively cooperate with the two positioning components 2. A belt 33 drives the two driven wheels 32, and the mounting plates 21 of both positioning components 2 are fixedly connected to the belt 33. Specifically, a pressure plate 6 is connected to the mounting plate 21, and the pressure plate 6 is fixedly connected to the belt 33.

[0030] Therefore, during operation, the telescopic drive 31 drives the mounting plate 21 to slide, thereby causing the two driven wheels 32 to rotate via the mounting plate 21. This, in turn, causes the mounting plate 21 of the other positioning component 2 to slide synchronously via the belt 33, enabling the positioning components 22 of the two sets of positioning components 2 to slide towards or away from each other. Thus, in the above structure, only one telescopic drive 31 is needed to drive the two positioning components 2 to slide simultaneously towards or away from each other, reducing costs and improving the processing efficiency of ceramic circuit boards.

[0031] Understandably, in other embodiments, the drive component 3 may not be equipped with a transmission component, and each positioning component 2 may be equipped with a telescopic drive component 31 to drive the positioning component 22 to move in order to adjust the position of the ceramic circuit board.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
