[0001] The utility model relates to the technical field of anti - folding devices, in particular to an anti - folding device for the surface of prepreg sheets. Background Technique

[0002] Prepreg sheets, also known as "PP sheets", are one of the main materials in the production of multilayer boards. They are mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as fiberglass cloth, paper base, and composite materials. Most of the prepreg sheets (bonding sheets) used in the production of multilayer printed boards use fiberglass cloth as the reinforcing material.

[0003] In the existing prepreg sheets during stacking, handling, and subsequent processing, due to the relatively soft and easily deformable material of the prepreg sheets themselves, traditional workers often lift multiple prepreg sheets at one time, and 4 - 5 people are required to lift them. The prepreg sheets are large and heavy, which easily causes problems such as folding and deformation on the surface of the prepreg sheets, not only affecting the product quality but also increasing the scrap rate. Therefore, an anti - folding device for the surface of prepreg sheets is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti - folding device for the surface of prepreg sheets to solve the problems raised in the above - mentioned background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti - folding device for the surface of prepreg sheets, including a stacking table, and a number of prepreg sheet bodies are placed on the top of the stacking table;

[0006] One side of the prepreg sheet body is provided with a lifting component, one side of the lifting component is provided with a limiting component, and one side of the limiting component is provided with a clamping component;

[0007] The lifting component includes a motor, a lead screw is fixed to the output shaft end of the motor, and a cross - plate is threadedly connected to the outside of the lead screw;

[0011] Preferably, a sliding column is fixed to the top of the stacking table and movably penetrates through one side of the cross - plate, and a limiting block for restricting the moving height of the cross - plate is fixed to the top of the sliding column.

[0012] Preferably, a plug rod is fixedly arranged at the top of the skateboard and movably penetrates through one side of the top of the fixing frame, a sliding rod is fixedly arranged at the bottom of the skateboard and movably penetrates through one side of the bottom of the fixing frame, and a pull rod is fixedly arranged at the bottom of the sliding rod.

[0013] Preferably, a first spring is sleeved outside the sliding rod, two sides of the first spring are respectively connected to one side of the first sliding groove and the skateboard, and the outside of the fixing frame is fixed to one side of the cross plate.

[0033] Embodiment

[0034] Please refer to Figure 1-8 , the present utility model provides a technical solution: an anti-fold device on the surface of a prepreg, including a stacking table 1. A mechanism for lifting it (not shown in the figure) is provided at the bottom of the stacking table 1, so that the stacking table 1 can move up and down when stacking the prepreg main body 5. A number of prepreg main bodies 5 are placed on the top of the stacking table 1; a lifting assembly 2 is provided on one side of the prepreg main body 5, a limiting assembly 4 is provided on one side of the lifting assembly 2, and a clamping assembly 6 is provided on one side of the limiting assembly 4;

[0035] The lifting assembly 2 includes a motor 21. A lead screw 22 is fixed to the output shaft end of the motor 21. A cross plate 23 is threadedly connected to the outside of the lead screw 22; a support rod 3 is rotatably connected to the top of the cross plate 23 through a damping bearing. The support rod 3 is used to support the prepreg main body 5 to be moved. The support rod 3 rotates 45 degrees so that the support rod 3 is located at the bottom of the prepreg main body 5. At this time, the support rod 3 supports the bottom of the prepreg main body 5 to prevent the surface of the prepreg main body 5 from being folded.

[0036] The top of the motor 21 is fixed to one side of the bottom of the stacking table 1. A sliding column 24 that movably penetrates one side of the cross plate 23 is fixed to the top of the stacking table 1. A limiting block 25 for restricting the moving height of the cross plate 23 is fixed to the top of the sliding column 24. The output shaft of the motor 21 rotates, and the output shaft drives the lead screw 22 to rotate, so that the cross plate 23 threadedly connected to the lead screw 22 moves up and down along the sliding column 24, and the cross plate 23 drives the support rod 3 to move up and down. At this time, prepreg main bodies 5 of different heights can be supported.

[0037] In order to facilitate the limitation of the protruding position of the support rod 3, such as Figure 4As shown, a limiting component 4 is provided. According to the actual situation, two support rods 3 can also be respectively provided on both sides of the stacking table 1;

[0038] The limiting component 4 includes a fixing frame 43. A first sliding groove 47 is opened inside the fixing frame 43. A sliding plate 48 is slidably connected to the inner side of the first sliding groove 47. A limiting hole 41 is opened on one side of the support rod 3. The number of the support rods 3, the motor 21, and the fixing frame 43 is at least two. A plug rod 42 that movably penetrates through one side of the top of the fixing frame 43 is fixed to the top of the sliding plate 48. A sliding rod 46 that movably penetrates through one side of the bottom of the fixing frame 43 is fixed to the bottom of the sliding plate 48. A pull rod 44 is fixed to the bottom of the sliding rod 46. When the pull rod 44 is pulled downward, when the limiting hole 41 on one side of the support rod 3 rotates to the top of the plug rod 42, a first spring 45 is sleeved outside the sliding rod 46. Two sides of the first spring 45 are respectively connected to one side of the first sliding groove 47 and the sliding plate 48. The outside of the fixing frame 43 is fixed to one side of the cross plate 23. Under the elastic force of the first spring 45, the sliding plate 48 is pushed to slide inside the first sliding groove 47, so that the sliding plate 48 pushes the plug rod 42 to insert inside the limiting hole 41. At this time, the position of the support rod 3 is limited.

[0039] The clamping component 6 includes a spherical ball 61. A second spring 64 is connected to the outside of the spherical ball 61. Two second sliding grooves 65 are opened inside the cross plate 23. A convex block 63 for restricting the spherical ball 61 is provided on the inner wall of the second sliding groove 65. A limiting groove 62 is opened at the bottom of the support rod 3. The bottom of the second spring 64 is connected to the bottom of the second sliding groove 65. The limiting groove 62 at the bottom of the support rod 3 moves toward the spherical ball 61. When the spherical ball 61 is inserted inside the limiting groove 62, at this time, under the elastic force of the second spring 64, the spherical ball 61 is pushed to abut against the inside of the limiting groove 62, so that the support rod 3 can be stably located on the top of the cross plate 23 when not in use.

[0040] When the plug rod 42 is inserted inside the limiting hole 41, the angle between the support rod 3 and the cross plate 23 is 45 degrees. When the spherical ball 61 is inserted inside the limiting groove 62, the support rod 3 and the cross plate 23 are in a parallel state. After each support is completed, only need to pull the pull rod 44 again and rotate the support rod 3 to release the limit, so as to prepare for the next support.

[0041] Working principle: When it is necessary to stack the semi-cured sheet body 5 to prevent surface folding, first control the output shaft of the motor 21 to rotate. The output shaft drives the lead screw 22 to rotate. When the lead screw 22 rotates clockwise, the cross plate 23 threadedly connected to the lead screw 22 moves upward along the sliding column 24, and at the same time drives the support rod 3 to move upward. When the output shaft of the motor 21 rotates counterclockwise, the cross plate 23 drives the support rod 3 to move downward. At this time, the semi-cured sheet body 5 at different heights can be supported to prevent the surface of the semi-cured sheet body 5 from folding.

[0042] Only two workers are needed to pull the prepreg sheet body 5 on both sides of the support rod 3, which reduces the number of workers required to move the prepreg sheet 5 and reduces the waste of labor.

[0043] Only need to rotate the support rod 3 so that the limiting groove 62 at the bottom of the support rod 3 moves away from the outside of the spherical ball 61, and pull down the pull rod 44. When the limiting hole 41 on one side of the support rod 3 rotates to the top of the insertion rod 42, stop rotating the support rod 3 and release the pulling force on the pull rod 44. At this time, under the elastic force of the first spring 45, the sliding plate 48 is pushed to slide inside the first sliding groove 47, so that the sliding plate 48 pushes the insertion rod 42 to insert inside the insertion rod 42. At this time, the position of the support rod 3 is limited to prevent the support rod 3 from rotating randomly when supporting the prepreg sheet body 5 to prevent surface folding;

[0044] After the worker finishes moving the stacked prepreg sheet body 5, only need to pull down the pull rod 44 again, and then rotate the support rod 3 so that the limiting groove 62 at the bottom of the support rod 3 moves towards the spherical ball 61. When the spherical ball 61 is inserted inside the limiting groove 62, at this time, under the elastic force of the second spring 64, the spherical ball 61 is pushed to abut against the inside of the limiting groove 62, so that the support rod 3 can be stably located on the top of the cross plate 23 when not in use.

[0045] In summary, by providing a support rod 3 on the side of the stacking table 1 and controlling the output shaft of the motor 21 to rotate in different directions and at different angles, so that the cross plate 23 is at different heights, the position of the support rod 3 can be adjusted. Whether it is rising or falling, it can be finely adjusted according to the actual height of the prepreg sheet body 5, avoiding problems such as surface folding and deformation of the prepreg sheet body 5 caused by uneven force or lack of support during stacking or moving, protecting the quality of the material, reducing the rejection rate. At the same time, only two workers are needed to move the prepreg sheet body 5 on both sides of the support rod 3, reducing the waste of labor. The support rod 3 ensures that the support strength is appropriate and can adapt to prepreg sheet bodies 5 of different thicknesses and different heights, enhancing the versatility of the device.

[0046] When supporting the prepreg sheet body 5, the position of the support rod 3 can be fixed by the separation of the limiting groove 62 from the spherical ball 61 and the insertion of the insertion rod 42 into the limiting hole 41, effectively preventing the support rod 3 from rotating randomly due to external forces during the support process, thus ensuring the stability and reliability of the support, avoiding the surface of the prepreg sheet body 5 from folding due to unstable support. Only by rotating the support rod 3 and pulling the pull rod 44 can the limit and unlocking be completed, without complicated adjustment steps or additional tools, improving the work efficiency of the workers.

[0047] Under the elastic force of the second spring 64, the ball 61 can tightly contact the inner side of the limiting groove 62, ensuring the stability of the support rod 3 when not in use and avoiding the movement or tipping of the support rod 3 due to external force or vibration. The support rod 3 is stored and stably fixed on the top of the horizontal plate 23, reducing the occupied space and improving the space utilization of the entire equipment or working area.
