DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-9 The present invention describes the above technical solution in detail through the following embodiments: The glass fiber punching and loading device comprises a fixed platform 1 and a punching mechanism 2 arranged above the fixed platform 1, and also comprises: A platform guide rail 3, one end of which is connected to the fixed platform 1, and the other end extending to the side of the fixed platform 1 is connected to the center base 4; The movable platform 5 is arranged on the moving platform guide rail 3 and reciprocates along the moving platform guide rail 3 between the processing position above the fixed platform 1 and the loading and unloading position on the side of the punching mechanism 2; The stage driving mechanism 6 is arranged on the central machine base 4 and connected to the movable stage 5 to drive the movable stage 5 to reciprocate along the moving stage guide rail 3; The loading and unloading turntable 7 is rotatably arranged on the central machine base 4. A loading hole 8 and a discharging hole 9 for the workpiece to enter are arranged on the outer side of the loading and unloading turntable 7 along the circumferential direction. The loading hole 8 and the discharging hole 9 are arranged along the radial direction of the loading and unloading turntable 7. The loading and unloading turntable 7 rotates so that the loading hole 8 and the discharging hole 9 are alternately moved to the loading and unloading position; A turntable driving mechanism 10, which is arranged on the central machine base 4 and connected to the loading and unloading turntable 7 to drive the loading and unloading turntable 7 to rotate; A workpiece clamping mechanism 11 is arranged on the loading and unloading turntable 7 and clamps and releases the workpiece to be processed that enters the loading hole 8; A pneumatic suction cup 12, which is located above the discharge hole 9; A lifting mechanism 13 is arranged on the top of the loading and unloading turntable 7 and is located between the central machine base 4 and the discharge hole 9. The lifting mechanism 13 is connected to the pneumatic suction cup 12 through a cantilever 14 to drive the pneumatic suction cup 12 to move up and down; The unloading plate 15 is arranged above the loading and unloading turntable 7 to receive the finished workpiece released by the pneumatic suction cup 12 , and the waste materials in the unloading hole 9 are transferred to the bottom of the unloading plate 15 by the rotation of the loading and unloading turntable 7 .

[0022] Specifically, after the workpiece on the movable carrier 5 is processed below the punching mechanism 2, the carrier driving mechanism 6 drives the movable carrier 5 to move to the loading and unloading position. At this time, the workpiece and waste on the movable carrier 5 enter the unloading hole 9 of the loading and unloading turntable 7. Subsequently, the lifting mechanism 13 drives the pneumatic suction cup 12 to descend, and the pneumatic suction cup 12 absorbs the workpiece and is driven to rise. Then the turntable driving mechanism 10 drives the loading and unloading turntable 7 to rotate until the workpiece in the loading hole 8 reaches the top of the movable carrier 5 at the loading and unloading position. In this process, the waste located at the unloading hole 9 on the movable carrier 5 falls from the movable carrier 5 as the loading and unloading turntable 7 rotates, making way for the subsequent workpiece. The workpiece clamping mechanism 11 releases the clamped workpiece to the movable carrier 5 below. At the same time, the workpiece that moves to the top of the unloading plate 15 as the loading and unloading turntable 7 rotates is released to the unloading plate 15 by the pneumatic suction cup 12, thereby realizing the synchronization of loading and unloading, and realizing the separation and export of waste and finished workpieces.

[0023] The present invention drives the loading and unloading turntable 7 provided with a loading hole 8 and a unloading hole 9 to rotate through a turntable driving mechanism 10, and cooperates with a workpiece clamping mechanism 11, a movable platform 5 driven by a platform driving mechanism 6, a pneumatic suction cup 12 driven by a lifting mechanism 13, and a blanking plate 15 located above the loading and unloading turntable 7, not only realizing the integration of loading and unloading, but also realizing the synchronization of loading and unloading, so as to improve production efficiency.

[0024] Moreover, the separation and export of finished workpieces and waste materials are achieved simultaneously during the unloading process, that is, unloading and unloading are carried out simultaneously, and there is no need to separate the finished workpieces and waste materials subsequently, which simplifies the operation process and further improves production efficiency.

[0025] Among them, the height difference between the lower surface of the loading and unloading turntable 7 and the upper surface of the movable platform 5 is smaller than the thickness of the workpiece to ensure that the workpiece can enter the loading hole 8 and the unloading hole 9, and the radius of the loading and unloading turntable 7 is larger than the length of the movable platform 5 to ensure that the workpiece on the movable platform 5 can fully enter the unloading hole 9, and ensure that the workpiece in the loading hole 8 can be fully supported on the movable platform 5.

[0026] Among them, the carrier driving mechanism 6 includes a screw 601 and a first stepper motor 602. The first stepper motor 602 is embedded in the side of the center base 4. A screw hole 16 matching the screw 601 is provided in the movable carrier 5. One end of the screw 601 passes through the screw hole 16 and is rotatably connected to the fixed carrier 1. Moving platform guide rails 3 are provided on both sides of the screw 601.

[0027] Among them, the turntable driving mechanism 10 includes a second stepper motor 1001 and a transmission shaft 1002 connected to the second stepper motor 1001, the loading and unloading turntable 7 is arranged on the transmission shaft 1002, and a positioning hole 17 for rotating and plugging the transmission shaft 1002 is provided on the top of the center base 4, and a motor cavity 18 for installing the second stepper motor 1001 is provided inside the center base 4. The motor cavity 18 is connected to the positioning hole 17 through an axial hole, and the transmission shaft 1002 is supported on the hole wall at the bottom of the positioning hole 17. The second stepper motor 1001 drives the loading and unloading turntable 7 to rotate through the transmission shaft 1002.

[0028] Among them, a workpiece clamping mechanism 11 is arranged on both sides of the loading hole 8, and the workpiece clamping mechanism 11 includes a clamping cylinder 1101, a clamping plate 1102 and a support plate 1103. The clamping cylinder 1101 is arranged on the top of the loading and unloading turntable 7, the upper end of the clamping plate 1102 is connected to the loading and unloading turntable 7, and the lower end extends into the loading hole 8, and the outer side of the support plate 1103 is connected to the lower end of the clamping plate 1102. The clamping plate 1102 is used to support the workpiece entering the loading hole 8. When the workpiece is transferred to the top of the movable carrier 5 at the loading and unloading position, the clamping plates 1102 on both sides and the support plates 1103 on both sides move away from each other, so that the workpiece falls on the movable carrier 5 below.

[0029] What is further optimized in the above embodiment is that the two side walls of the charging hole 8 are provided with clearance holes 19 for the clamping plate 1102 and the supporting plate 1103 to enter.

[0030] Further optimized in the above embodiment is that the workpiece clamping mechanism 11 further includes a sleeve 1104, a guide rod 1105, a spring 1106, a T-shaped slider 1107, an inclined rod 1108 and a sliding ring 1109, at least two sliding holes 20 connected to the clearance hole 19 are provided on both sides of the loading hole 8, and the sleeve 1104 is located in the sliding hole 20; A T-shaped slot 21 is provided along the length direction on the back of the clamping plate 1102. A T-shaped slider 1107 is slidably disposed in the T-shaped slot 21 and connected to one end of the sleeve 1104. One end of the guide rod 1105 is slidably plugged into the sleeve 1104, and the other end is connected to the wall of the sliding hole 20. The sliding ring 1109 and the spring 1106 are both movably mounted on the sleeve 1104, and the two ends of the spring 1106 are respectively connected to the clamping plate 1102 and the sliding ring 1109, and the side of the sliding ring 1109 is connected to the back of the clamping plate 1102 through the inclined rod 1108, and the inclined rod 1108 is hinged to the sliding ring 1109 and the clamping plate 1102, and one end of the inclined rod 1108 connected to the clamping plate 1102 is inclined toward the closed end of the charging hole 8, and a movable hole 22 extending into the charging hole 8 for the inclined rod 1108 to move is provided on one side of the hole wall of the sliding hole 20; The clamping cylinder 1101 is connected to a linkage rod 23, and both ends of the linkage rod 23 extend into two sliding holes 20 respectively and are connected to corresponding sliding rings 1109; The length of the clamping plate 1102 and the supporting plate 1103 is smaller than the length of the charging hole 8 , and the initial position of the clamping plate and the supporting plate 1103 is close to the opening end of the charging hole 8 .

[0031] Specifically, when the workpiece enters the loading hole 8, the two sides of the workpiece are respectively supported on the support plates 1103 on both sides and are located between the two side clamps 1102. When the clamping cylinder 1101 pushes the two sliding rings 1109 with the help of the linkage rod 23, the sliding ring 1109 pushes the clamp 1102 with the help of the spring 1106. When the workpiece is clamped by the clamps 1102 on both sides, if the workpiece does not conflict with the closed end of the loading hole 8 at this time, with the further push of the clamping cylinder 1101, the sliding ring 1109 overcomes the resistance of the spring 1106 and approaches the clamp 1102, thereby pushing the inclined rod 1108 to rotate, so that the inclined rod 1108 tends to be parallel to the clamp 1102, so that the inclined rod 1108 pushes the clamp 1102 to move toward the closed end of the loading hole 8, so that the clamped workpiece moves toward the closed end of the loading hole 8, which is helpful for positioning the workpiece and provides guarantee for the normal operation of the subsequent punching and unloading links.

[0032] The glass fiber punching and loading device also includes a loading plate 24 , the discharge end of which is in an arc shape that fits the clearance of the outer side of the loading and unloading turntable 7 , and the loading plate 24 is used to transport the workpiece to be processed to the loading hole 8 .

[0033] The glass fiber punching and loading device also includes a waste plate 25 arranged on one side of the loading and unloading position, one end of the waste plate 25 is gap-matched with the side surface of the movable carrier 5 at the loading and unloading position, and a waste trough 26 for the workpiece to enter and move is provided on the top of the waste plate 25. When the loading and unloading turntable 7 rotates, the waste in the unloading hole 9 is driven to rotate above the waste trough 26. As the loading and unloading turntable 7 rotates, the waste in the unloading hole 9 gradually falls into the waste trough 26 under the push of the hole wall on one side of the waste hole. Due to the limitation of the groove walls on both sides of the waste trough 26, after entering the waste trough 26, the waste will not move along the arc path with the rotation of the loading and unloading turntable 7, but will move along the waste trough 26.

[0034] In addition, two discharge holes 9 and two charging holes 8 are provided, the charging holes 8 are perpendicular to the discharge holes 9, the two charging holes 8 are arranged along a straight line, and the two discharge holes 9 are arranged along a straight line; There are two punching mechanisms 2, fixed carrier 1, movable carrier 5, workpiece clamping mechanism 11, pneumatic suction cup 12, lifting mechanism 13, unloading plate 15, loading plate 24 and waste plates 25. The two waste plates 25 are centrally symmetrical about the axis of the loading and unloading turntable 7, so that when the loading and unloading turntable 7 rotates, the punching mechanisms 2 on both sides can be loaded and unloaded at the same time.

[0035] It is known from common technical knowledge that the present application can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
