Description

Technical Field

[0001] This application relates to the technical field of blank plate cutting, and particularly to a blank plate fixing mechanism. Background Art

[0002] With the miniaturization and high performance of electronic devices, the requirements for the accuracy and stability of various electronic components are getting higher and higher. As a common temperature sensing element, NTC thermistors are widely used in fields such as temperature measurement, temperature compensation, and current control. In the production process of NTC thermistors, the processing and cutting of blank plates are one of the key steps to ensure their performance and quality.

[0003] In the prior art, NTC blank plates are usually fixed by mechanical jigs and then cut. However, traditional fixing methods often rely on mechanical clamping, which may generate uneven stress on the blank plate, thus easily causing deformation or position deviation of the blank plate during the cutting process.

[0004] Therefore, how to ensure the stability of the NTC blank plate during the cutting process and avoid deformation or position deviation caused by uneven stress due to mechanical clamping is a difficult problem that needs to be solved currently. Summary of the Utility Model

[0005] In order to effectively avoid the problem of uneven stress caused by mechanical clamping by using the design of magnetic fixing and precision positioning pins, and to achieve precise positioning and stable fixing of the blank plate, thereby improving the cutting accuracy, this application provides a blank plate fixing mechanism. The following technical solutions are provided in this application:

[0006] A blank plate fixing mechanism includes a bottom plate, an NTC blank plate, and a fixing plate. A through groove is vertically formed on the bottom plate, a stepped surface is provided on the inner side wall of the through groove, the NTC blank plate is arranged on the stepped surface, the fixing plate is hollow and arranged on the NTC blank plate, and the fixing plate is magnetically connected to the stepped surface.

[0007] In a specific feasible implementation, a magnet block is provided on the bottom surface of the fixing plate, a second through hole for the magnet block to pass through is formed on the NTC blank plate, the stepped surface is an iron plate, and the magnet block passes through the second through hole and is magnetically connected to the stepped surface.

[0008] In a specific feasible implementation, a plurality of magnet blocks are provided, and the plurality of magnet blocks are evenly arranged on the bottom surface of the fixing plate, and a plurality of second through holes are also formed.

[0009] In a specific feasible implementation, a positioning pin is provided on the top surface of the stepped surface, and a first through hole for the positioning pin to pass through is formed on the NTC blank plate.

[0010] In a specific feasible implementation, a relief groove for the positioning pin to pass through is provided on the fixed plate.

[0011] In a specific feasible implementation, a plurality of positioning pins are provided. The plurality of positioning pins are evenly arranged on the peripheral side of the top surface of the step surface, and a plurality of first through holes and relief grooves are also provided.

[0012] In a specific feasible implementation, a first linear module and a second linear module are connected to the bottom plate. The bottom plate is arranged on the second linear module, and the second linear module is arranged on the first linear module; the first linear module is used to drive the bottom plate to move along the y-axis direction, and the second linear module is used to drive the bottom plate to move along the x-axis direction.

[0013] In a specific feasible implementation, chamfering treatments are performed on the corners of the NTC material plate and the fixed plate.

[0014] In summary, the beneficial effects of this application at least include:

[0015] 1) By the cooperation of the positioning pins on the step surface and the first through holes of the NTC material plate, together with the relief grooves on the fixed plate, it ensures that the NTC material plate can be accurately positioned and fixed during the cutting process. This can effectively avoid the errors caused by the position deviation of the material plate during cutting and improve the cutting accuracy.

[0016] 2) A plurality of evenly distributed magnet blocks are provided on the bottom surface of the fixed plate. These magnet blocks pass through the second through holes on the NTC material plate and are magnetically connected to the iron plate on the step surface. Compared with the traditional mechanical clamping method, this magnetic connection can avoid stress concentration and material plate deformation caused by uneven clamping, thereby improving the fixing stability and cutting accuracy.

[0017] 3) The first linear module and the second linear module provided on the bottom plate can achieve the precise movement of the bottom plate, enabling the NTC material plate to be accurately adjusted in the x-axis and y-axis directions. This design improves the flexibility and adaptability of the fixing mechanism.

[0018] The inner sidewall of the through groove on the bottom plate is provided with a stepped surface, providing a stable bearing surface, enabling the NTC material plate to be placed stably on the stepped surface, thereby reducing the deformation or displacement problems that may be caused by unstable fixation. A magnetic connection is adopted between the fixing plate and the stepped surface. This design avoids the disadvantages of traditional mechanical jigs applying uneven stress to the material plate. The magnetic attraction method can be evenly distributed around the material plate, ensuring that the material plate will not be deformed or displaced due to excessive local stress during the fixing process, thereby improving the accuracy and stability of the cutting process. The hollow design of the fixing plate ensures that the surface of the material plate is not oppressed, and at the same time allows the material plate to maintain its shape and accuracy while being fixed. Such a design does not require additional mechanical force during fixation, and stable and reliable fixation can be achieved only through magnetic attraction force, further reducing the stress concentration problem caused by fixing pressure. Through the above design, the material plate fixing mechanism effectively solves the problems of unstable fixing of the material plate and deformation and position offset caused by uneven stress in the prior art due to mechanical clamping methods, ensuring the cutting accuracy.

[0027] An embodiment of the present application discloses a material plate fixing mechanism.

[0028] Referring to Figure 1 and Figure 2 , the material plate fixing mechanism includes a bottom plate 1, an NTC material plate 2, and a fixing plate 3. A through groove 11 is provided on the bottom plate 1 in the vertical direction. A stepped surface 12 is fixedly connected to the inner side wall of the through groove 11. The NTC material plate 2 is placed on the top surface of the stepped surface 12. The fixing plate 3 is hollow and placed on the top surface of the NTC material plate 2. The bottom surface of the fixing plate 3 is magnetically connected to the top surface of the stepped surface 12, thereby fixing the NTC material plate 2.

[0029] Referring to Figure 1 and Figure 2, a plurality of magnet blocks 31 are fixedly connected to the bottom surface of the fixing plate 3. A plurality of second through holes 22 are formed in the NTC material plate 2, and the second through holes 22 correspond to the magnet blocks 31 one by one. The stepped surface 12 is an iron plate, and the magnet blocks 31 pass through the corresponding second through holes 22 and are magnetically adsorbed to the stepped surface 12. Due to the corresponding arrangement of the magnet blocks 31 and the second through holes 22, the magnetic adsorption force can be evenly distributed on the surface of the NTC material plate 2. This uniform magnetic force distribution reduces local stress concentration, avoids material deformation or damage caused by uneven clamping, and improves the fixing stability of the material plate. The setting of the magnet blocks 31 makes the fixing process simple and fast. The operator can easily align the NTC material plate 2 with the corresponding second through holes 22 for fixing without complex mechanical clamping adjustment. This simplified operation method improves work efficiency and also reduces fixing errors caused by improper operation. The above design greatly enhances the fixing effect, ensures that the NTC material plate 2 does not shift during the cutting process, and prevents the material plate deformation or displacement problems that may be caused by traditional fixing methods.

[0030] Referring to Figure 1 and Figure 2 , a plurality of positioning pins 4 are fixedly installed on the top surface of the stepped surface 12. A plurality of first through holes 21 are formed in the NTC material plate 2, and a plurality of relief grooves 32 are formed in the fixing plate 3. The first through holes 21, the relief grooves 32 and the positioning pins 4 correspond to each other one by one. The plurality of positioning pins 4 are evenly arranged on the circumferential side of the top surface of the stepped surface 12. Each positioning pin 4 sequentially passes through the corresponding first through hole 21 and the relief groove 32, thereby completing the precise positioning of the NTC material plate 2. The positioning pins 4 cooperate with the stepped surface 12 through the first through holes 21 and the relief grooves 32 to provide stable mechanical support. The uniform arrangement of each positioning pin 4 not only improves the fixing stability, but also ensures that the NTC material plate 2 does not shift or tilt during the entire fixing process, thus ensuring the stability and accuracy of the cutting process. The setting of the relief grooves 32 allows the positioning pins 4 to have a certain moving space on the fixing plate 3, enabling the positioning and fixing process to adapt to certain deviations and adjustments. This flexibility makes the NTC material plate 2 more convenient to adjust and operate in practical applications, improving the adaptability and work efficiency of the fixing mechanism. In addition, the corners of the NTC material plate 2 and the fixing plate 3 are chamfered, which can make the material plate easier to align during installation and positioning. Especially in multi-step processes, this design helps to quickly and accurately position.

[0031] Referring to Figure 1 and Figure 2, the material plate fixing mechanism further includes a first linear module 5 and a second linear module 6. The bottom plate 1 is fixedly installed on the second linear module 6, and the second linear module 6 is fixedly installed on the first linear module 5. Among them, the first linear module 5 is arranged along the y-axis direction, and the second linear module 6 is arranged along the x-axis direction. The first linear module 5 is used to drive the bottom plate 1 to move along the y-axis direction, and the second linear module 6 is used to drive the bottom plate 1 to move along the x-axis direction. The first linear module 5 and the second linear module 6 can achieve the precise movement of the bottom plate 1, so that the NTC material plate 2 can be accurately adjusted in the x-axis and y-axis directions.

[0032] In summary, the material plate fixing mechanism solves the problems of unstable fixing and inaccurate positioning existing in the traditional fixing methods by combining magnetic fixing and precise positioning technologies. The stepped surface 12 provided on the bottom plate 1 and the magnet block 31 on the bottom surface of the fixing plate 3 are magnetically connected, and the uniformly distributed magnetic force avoids material deformation or damage and improves the fixing stability. The cooperation of the positioning pin 4, the first through hole 21 and the relief groove 32 ensures the precise positioning and stable support of the NTC material plate 2 and reduces the fixing error caused by improper operation. At the same time, the setting of the first linear module 5 and the second linear module 6 allows the bottom plate 1 to be precisely adjusted in the x-axis and y-axis directions, further improving the adaptability and working efficiency of the fixing mechanism. The overall design simplifies the operation process, improves the cutting accuracy, and ensures the stability and accuracy of the NTC material plate 2 during the processing.

[0033] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
