Description

Technical Field

[0001] This utility model mainly relates to the field of automotive parts manufacturing technology, specifically to a thermoforming loading and unloading clamping mechanism. Background Technology

[0002] Thermoforming, also known as hot pressing, is a processing method for plastic sheets. In the production of automotive parts, thermoforming is generally used to produce parts. After processing, the thermoformed parts are clamped by loading and unloading clamping mechanisms.

[0003] The conventional loading and unloading clamping mechanism directly drives the clamping plate to abut against the thermoformed parts. This clamping method is prone to damaging the thermoformed parts, thus affecting the clamping effect on automotive parts. Utility Model Content

[0004] This utility model mainly provides a thermoforming loading and unloading clamping mechanism to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A thermoforming loading and unloading clamping mechanism includes a fixed plate, a rotating plate rotatably connected to the fixed plate, and a spacing adjustment mechanism installed on the rotating plate. The spacing adjustment mechanism includes a sliding frame connected to the rotating plate and two symmetrically located and sliding within the sliding frame.

[0007] The nut seat is provided with a clamping assembly, which includes two fixed posts connected to the two nut seats respectively and having openings at the top, an electric push rod installed inside the fixed posts, an extension post connected to the output rod of the electric push rod and sliding inside the fixed posts while having an opening at the bottom, a fixed plate disposed inside the fixed posts, and a movable plate disposed at the inner end of the extension post.

[0008] Optionally, a first motor is mounted at the center of the back of the fixed disk, and the output shaft of the first motor passes through the fixed disk and is connected to the rotating disk.

[0009] Optionally, a concave bracket is installed on the fixing plate outside the first motor.

[0010] Optionally, a rotating ring is installed at the bottom of the rotating disk, and an arc-shaped ring surrounds the rotating ring. A groove adapted to the arc-shaped ring is provided on the inner wall of the fixed disk.

[0011] Optionally, the spacing adjustment mechanism further includes a bidirectional lead screw rotatably connected inside the sliding frame, a second motor disposed outside the sliding frame and connected to the bidirectional lead screw, and two lead screw seats symmetrically slidably connected to the bidirectional lead screw.

[0012] Optionally, the fixed plate and the movable plate are provided with rubber pads on their adjacent sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a clamping assembly to clamp the top and bottom sides of a thermoformed part separately, eliminating the need for clamping from both sides. This reduces the need for excessive clamping force, preventing damage to the thermoformed part, and provides a better clamping effect, allowing for stable loading and unloading.

[0015] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] This application provides a thermoforming loading and unloading clamping mechanism, as shown in the schematic diagram below. Figure 1-4 As shown. The thermoforming loading and unloading clamping mechanism includes a fixed plate 10, a rotating plate 20 rotatably connected to the fixed plate 10, and a spacing adjustment mechanism 30 installed on the rotating plate 20. The spacing adjustment mechanism 30 includes a sliding frame 31 connected to the rotating plate 20 and two symmetrically located and sliding within the sliding frame 31.

[0025] A clamping assembly 40 is provided on the nut seat 33. The clamping assembly 40 includes two fixed posts 41 that are respectively connected to the two nut seats 33 and have openings at the top, an electric push rod 45 installed inside the fixed posts 41, an extension post 42 that is connected to the output rod of the electric push rod 45 and slides inside the fixed posts 41 and has an opening at the bottom, a fixed plate 43 that is provided inside the fixed posts 41, and a movable plate 44 that is provided at the inner end of the extension post 42.

[0026] It should also be noted that all electrical components of this device are electrically connected to a conventional PLC controller.

[0027] For details, please refer to the appendix. Figure 2 A first motor 50 is installed at the center of the back of the fixed disk 10, and the output shaft of the first motor 50 passes through the fixed disk 10 and is connected to the rotating disk 20.

[0028] It should be noted that in this embodiment, the first motor 50 can be operated to rotate the rotary disk 20, thereby adjusting the angle of the clamping assembly 40 to ensure effective clamping of the thermoformed part.

[0029] For details, please refer to the appendix. Figure 2 A concave bracket 11 is installed on the fixing plate 10 outside the first motor 50.

[0030] It should be noted that, in this embodiment, the concave frame 11 can be used to connect with other robotic arms.

[0031] For details, please refer to the appendix. Figure 2 A rotating ring 21 is installed at the bottom of the rotating disk 20, and an arc-shaped ring 22 is surrounded around the rotating ring 21. A groove that matches the arc-shaped ring 22 is provided on the inner wall of the fixed disk 10.

[0032] It should be noted that, in this embodiment, the rotating disk 20 can rotate stably due to the constraint of the arc ring 22.

[0033] For details, please refer to the appendix. Figure 3 The spacing adjustment mechanism 30 also includes a bidirectional lead screw 32 rotatably connected inside the sliding frame 31, a second motor 34 disposed outside the sliding frame 31 and connected to the bidirectional lead screw 32, and two lead screw seats 33 symmetrically slidably connected to the bidirectional lead screw 32.

[0034] It should be noted that in this embodiment, the operation of the second motor 34 can cause the bidirectional lead screw 32 to rotate, thereby causing the two lead screw seats 33 to move synchronously and in opposite directions, so that the distance between the clamping components 40 on both sides can be adjusted, thereby clamping thermoformed parts of different widths.

[0035] For details, please refer to the appendix. Figure 3 The fixed plate 43 and the movable plate 44 are provided with rubber pads on their adjacent sides.

[0036] It should be noted that, in this embodiment, the rubber pad can increase the frictional resistance, thereby more effectively clamping the thermoformed parts for loading and unloading.

[0037] The specific operation method of this utility model is as follows:

[0038] First, adjust the spacing of the clamping components 40 on both sides according to the width of the thermoformed parts to be loaded and unloaded. Then, by operating the second motor 34, the bidirectional lead screw 32 can be rotated, thereby causing the two lead screw seats 33 to move synchronously and in opposite directions, thus making adjustments.

[0039] Then, the electric push rod 45 is operated to move the moving plate 44 away from the fixed plate 43, and the moving plate 44 and the fixed plate 43 are respectively located at the top and bottom of the thermoformed part. Then, the spacing adjustment mechanism 30 adjusts the spacing again, and at the same time, the electric push rod 45 retracts, so that the moving plate 44 and the fixed plate 43 fix the top and bottom of the thermoformed part respectively, thereby enabling effective loading and unloading.

[0040] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
