Description

Technical Field

[0001] This invention relates to the field of magnetic sheet processing equipment technology, and specifically to a magnetic sheet spacing stretching mechanism. Background Technology

[0002] During the production and processing of magnetic sheets, controllable gaps need to be formed between the magnetic sheets before some processes. For example, before applying powder, gaps need to be formed between the magnetic sheets to ensure that the powder is applied evenly. Also, before packaging, gaps between the magnetic sheets can prevent problems such as collisions and inconvenience in handling after packaging.

[0003] Therefore, in some scenarios, brushes or dials are used to mechanically push the magnetic sheets apart one by one, creating gaps. In other scenarios, a vacuum adsorption platform is used to lift and lower the magnetic sheets in sections, using the height difference and their own weight to achieve separation. However, the brush or dial method is sensitive to differences in sheet thickness and cannot adapt to magnetic sheets of varying thicknesses. Furthermore, the brush bristles can easily contaminate the magnetic sheets, affecting the yield rate. On the other hand, the section lifting method requires multiple vacuum pumps and lifting cylinders, resulting in high equipment costs, high energy consumption, and limited applicability.

[0004] Therefore, this application studies a magnetic sheet spacing stretching mechanism, which enables control of equipment costs, improves applicability, and better guarantees product yield. Utility Model Content

[0005] In order to control equipment costs, improve applicability, and better ensure product yield, this application provides a magnetic sheet spacing stretching mechanism.

[0006] This application provides a magnetic sheet spacing stretching mechanism, which adopts the following technical solution: A magnetic sheet spacing stretching mechanism includes an elastic band, two sets of clamping members, and a driving member. The two sets of clamping members are respectively installed at both ends of the elastic band. The driving member drives the two sets of clamping members to move in directions that are closer to each other or further apart from each other. When the clamping members move in the direction that are closer to each other, the clamping members drive the elastic band to stretch to both sides, so that a gap is generated between the products on the elastic band.

[0007] By adopting the above technical solution, the clamping component is driven to move in opposite directions by the driving component, which can precisely control the stretching degree of the elastic band, thereby flexibly adjusting the spacing between the magnetic sheets. This can meet the requirements of uniform powdering or boxing, while avoiding the problems of brush and dial methods being sensitive to magnetic sheet thickness differences and contaminating the magnetic sheets. This better ensures product yield, and the structure is simple, the manufacturing cost is low, the equipment cost can be controlled, and the applicability is improved.

[0008] Optionally, the clamping member includes a fixing plate and a clamping plate, the fixing plate and the clamping plate being rotatably connected; during installation, the elastic band passes between the fixing plate and the clamping plate, and the fixing plate and the clamping plate are connected to clamp the elastic band.

[0009] By adopting the above technical solution, the elastic band can be firmly fixed, ensuring the stability of the elastic band during the stretching process, and further improving the reliability of the magnetic sheet spacing stretching.

[0010] Optionally, the clamping member further includes a fixing member, which includes a plurality of bolts, the bolts passing through the fixing plate and screwed to the clamping plate; or the bolts passing through the fixing plate and the elastic band in sequence and screwed to the clamping plate.

[0011] By adopting the above technical solution, the fixing effect of the clamping component on the elastic band is further enhanced.

[0012] Optionally, the fixing plate has a fixing groove, and a fixing strip is formed on at least one side of the fixing groove. The clamping plate has a clamping groove that cooperates with the fixing strip and a clamping strip that cooperates with the fixing groove. When the fixing plate and the clamping plate clamp the elastic band, the fixing strip is inserted into the clamping groove and the clamping strip is inserted into the fixing groove.

[0013] By adopting the above technical solution, through the cooperation of the fixing groove and the clamping groove, and the mutual insertion of the fixing strip and the clamping strip, a tighter and more stable clamping structure is formed, which effectively prevents the elastic band from loosening or slipping during the stretching process.

[0014] Optionally, the driving component includes a motor and a bidirectional lead screw, and the two sets of clamping members are respectively installed on opposite threaded sides of the bidirectional lead screw. The motor drives the bidirectional lead screw to move the two sets of clamping members in a direction that is closer to or further away from each other.

[0015] By adopting the above technical solution, the spacing between magnetic sheets can be adjusted quickly and accurately, improving production efficiency while reducing equipment energy consumption. The structure is simple, further enriching and improving applicability.

[0016] Optionally, it also includes mounting seats corresponding to the clamping members one by one, with the opposite threaded sides of the bidirectional lead screw respectively screwed to the two mounting seats, and the clamping members mounted on the mounting seats.

[0017] Optionally, the output end of the motor is fitted with a belt, and the other end of the belt is fitted onto one end of the bidirectional lead screw, and the motor drives the bidirectional lead screw to rotate through the belt.

[0018] By adopting the above technical solution, the power transmission between the motor and the bidirectional lead screw is made smoother, reducing vibration and noise during the transmission process and improving the stability of equipment operation.

[0019] Optionally, a support plate may also be included, which supports the elastic band.

[0020] By adopting the above technical solution, the support plate provides additional support for the elastic band, ensuring that the elastic band remains flat during the stretching process and avoiding uneven magnetic sheet spacing caused by deformation or sagging of the elastic band, thereby further improving the accuracy and reliability of magnetic sheet spacing stretching.

[0021] Optionally, a displacement sensor is also included, which is disposed on at least one of the clamping members for detecting changes in the distance between the two clamping members.

[0022] By adopting the above technical solution, the distance between the two clamping parts can be detected in real time, thereby determining the stretching distance of the elastic band, and judging whether the spacing between the magnetic sheets meets the requirements by the stretching distance of the elastic band.

[0023] Optionally, it also includes a guide rail, and the clamping component is equipped with a guide block that mates with the guide rail.

[0024] Optionally, the clamping element includes a fixed shaft connected to the end of the elastic band.

[0025] In summary, this application includes the following beneficial technical effects: 1. By driving the clamping parts to move in opposite directions, the stretching of the elastic band can be precisely controlled, thereby flexibly adjusting the spacing between the magnetic sheets. This can meet the requirements of uniform powdering or boxing, while avoiding the problems of sensitivity to magnetic sheet thickness differences and magnetic sheet contamination caused by brush and dial methods. This better ensures product yield, and the structure is simple, the manufacturing cost is low, the equipment cost can be controlled, and the applicability is improved. 2. The elastic band can be firmly fixed by the fixing plate and the clamping plate, ensuring the stability of the elastic band during the stretching process and further improving the reliability of the magnetic sheet spacing stretching; 3.

The simple structure further enriches and enhances applicability. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a magnetic sheet spacing stretching mechanism. (Refer to...) Figure 1 The magnetic sheet spacing stretching mechanism includes an elastic band 1, two sets of clamping members 2, and a driving member 3. The elastic band 1 has good tensile recovery and a smooth surface. The two sets of clamping members 2 are respectively installed at both ends of the elastic band 1. The driving member 3 drives the two sets of clamping members 2 to move in directions that are closer to each other or further apart. When the clamping members 2 move in the direction that are closer to each other, the clamping members 2 drive the elastic band 1 to stretch to both sides, thereby creating a gap between the products on the elastic band 1. In this embodiment, the product is a magnetic sheet. The magnetic sheet is placed on the elastic band 1, and the driving member 3 drives the clamping members 2 to move in the direction that are closer to each other. The clamping members 2 drive the elastic band 1 to stretch, thereby creating a gap between the magnetic sheets on the elastic band 1. After completion, the magnetic sheet is transferred to powdering or boxing. When the next set of magnetic sheets needs to be placed, the clamping members 2 are moved back in the direction that are further apart, so that the elastic band 1 returns to its original state. After the unseparated magnetic sheets are placed, the elastic band 1 is stretched and the above operation is repeated. The spacing between the magnetic sheets is stretched by the elastic band 1, resulting in a simple structure, low manufacturing cost, and wide applicability.

[0031] Reference Figure 1 and Figure 2In some embodiments, the clamping member 2 includes a fixing plate 21 and a clamping plate 22, which are rotatably connected. In this embodiment, the fixing plate 21 and the clamping plate 22 are connected near their respective sides by hinges, thus creating a space between the two hinges through which the elastic band 1 passes. During installation, the elastic band 1 passes between the fixing plate 21 and the clamping plate 22, and the fixing plate 21 and the clamping plate 22 clamp the elastic band 1. The elastic band 1 is stretched from one side of the hinge to the other side and clamped by the fixing plate 21 and the clamping plate 22, thus stably fixing the elastic band 1.

[0032] In some embodiments, the clamping member 2 further includes a fixing member 23, which includes multiple bolts. The bolts pass through the fixing plate 21 and are screwed onto the clamping plate 22; or the bolts pass sequentially through the fixing plate 21 and the elastic band 1, and are screwed onto the clamping plate 22. The figure shows three bolts evenly spaced. The number of bolts can be set as needed. Whether the bolts pass through the elastic band 1 depends on the bolt's position and can be adjusted according to actual needs. The bolts further stabilize the elastic band 1.

[0033] In some embodiments, the fixing plate 21 has a fixing groove 4 along its length, and a fixing strip 5 is formed on at least one side of the fixing groove 4. The clamping plate 22 has a clamping groove 6 that cooperates with the fixing strip 5, and a clamping strip 7 that cooperates with the fixing groove 4. When the fixing plate 21 and the clamping plate 22 clamp the elastic band 1, the fixing strip 5 is inserted into the clamping groove 6, and the clamping strip 7 is inserted into the fixing groove 4. In this embodiment, two fixing grooves 4 are provided, and two fixing strips 5 are provided. In other embodiments, the number of fixing grooves 4 can be determined according to actual conditions such as the width of the fixing plate 21 and the clamping plate 22. Through the cooperation of the fixing grooves 4, fixing strips 5, clamping strips 7, and clamping grooves 6, the elastic band 1 can be further stabilized, thereby stretching the spacing between the magnetic sheets more stably.

[0034] Reference Figure 2 and Figure 3 In some embodiments, the driving component 3 includes a motor 31 and a bidirectional lead screw 32. Two sets of clamping members 2 are respectively mounted on opposite threaded sides of the bidirectional lead screw 32. The motor 31 drives the bidirectional lead screw 32 to move the two sets of clamping members 2 in directions that are closer to or further away from each other. This results in a simple structure, low manufacturing cost, and wider applicability to different scenarios. This embodiment also includes a mounting platform 9 and two fixed seats 10. The fixed seats 10 are screwed to the mounting platform 9, and the opposite threaded sides of the bidirectional lead screw 32 are respectively screwed to the two fixed seats 10.

[0035] In some embodiments, the system further includes mounting bases 8 corresponding to the clamping members 2 one by one. The opposite threaded sides of the bidirectional lead screw 32 are screwed to the two mounting bases 8 respectively. The clamping member 2 is mounted on the mounting base 8. The fixing plate 21 of the clamping member 2 is screwed to the mounting base 8. The mounting base 8 is located between the two fixing bases 10. The bidirectional lead screw 32 drives the mounting base 8 to move, thereby driving the clamping member 2 to move.

[0036] In some embodiments, a belt 11 is fitted onto the output end of the motor 31, and the other end of the belt 11 is fitted onto one end of the bidirectional lead screw 32. The motor 31 drives the bidirectional lead screw 32 to rotate via the belt 11. This allows the motor 31 to drive the bidirectional lead screw 32 to rotate more stably.

[0037] In some embodiments, a support plate 12 is also included, which supports the elastic band 1. In this embodiment, a support platform 13 is provided on the mounting platform 9, and the support plate 12 is screwed between the support platforms 13. A bidirectional lead screw 32 is provided below the support plate 12. The support plate 12 supports the elastic band 1, thereby increasing the supporting force of the elastic band 1, so as to better support the magnetic sheet and thus more accurately stretch the spacing.

[0038] In some embodiments, the device further includes a guide rail 14, and a guide block 15 is mounted on the clamping member 2, the guide block 15 cooperating with the guide rail 14. The guide rail 14 is screwed to the mounting platform 9, and two guide rails 14 are spaced apart. Guide blocks 15 are screwed to both ends of the fixing plate 21, cooperating with the guide rails 14 one by one. Through the cooperation of the guide blocks 15 and the guide rails 14, the clamping plate 22 can move more stably.

[0039] In some embodiments, a displacement sensor is further included, which is disposed on at least one of the clamping members 2, for detecting changes in the distance between the two clamping members 2. In this embodiment, one displacement sensor is disposed on any one of the clamping members 2, so that the distance between the two clamping members 2 can be detected in real time, thereby determining the stretching distance of the elastic band 1, and determining whether the distance between the magnetic sheets meets the requirements based on the stretching distance of the elastic band 1.

[0040] In other embodiments, the clamping member 2 includes a fixed shaft connected to the end of the elastic band 1. Specifically, the driving member 3 drives the fixed shaft to move. The fixed shaft can be fixed by means of bearing connection or other methods, and the driving member 3 drives the bearing to move the fixed shaft. The end of the elastic band 1 can be fixed to the fixed shaft by means of adhesive, snap-fit, or other methods, or the end of the elastic band 1 can be fixed by wrapping it around the fixed shaft one or several times.

[0041] The implementation principle of the magnetic sheet spacing stretching mechanism in this application embodiment is as follows: the driving component 3 drives the clamping component 2 to move in the opposite direction, which can precisely control the stretching degree of the elastic band 1, thereby flexibly adjusting the spacing between the magnetic sheets. This can meet the requirements of uniform powder spreading or boxing, while avoiding the problems of sensitivity to magnetic sheet thickness differences and magnetic sheet contamination caused by brush and dial methods. This better ensures product yield, and the structure is simple, the manufacturing cost is low, the equipment cost can be controlled, and the applicability is improved.
