Description

Technical Field

[0001] This utility model relates to the field of metal part cutting technology, and more specifically, it relates to a cutting mechanism for injection molding of metal insert components. Background Technology

[0002] In the injection molding production of metal insert components, the feeding mechanism is a crucial link in ensuring smooth production processes and stable product quality. The accuracy of the metal parts' position during conveying and injection molding has a vital impact on the subsequent gripping operation of the robotic arm and the efficiency and quality of the entire injection molding process.

[0003] Currently, in the blanking technology for injection molding of metal insert components on the market, the metal parts are prone to positional deviation during the conveying stage. This is because the conveying device may be affected by various factors during operation, such as uneven wear of the conveyor belt, fluctuations in the speed of the drive motor, and center of gravity shifts caused by the irregular shape of the metal parts themselves. These factors can cause the metal parts to gradually deviate from their preset position along the conveying path.

[0004] When the metal part shifts position, the robotic arm cannot accurately grasp it according to the pre-set gripping position during subsequent clamping operations. To ensure the metal part is correctly placed into the injection mold, the robotic arm must perform additional position adjustment. This extra adjustment process not only increases the complexity and time cost of the robotic arm's movements but also increases the risk of collisions between the robotic arm and surrounding equipment or metal parts, affecting the normal operation and lifespan of the equipment. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figure 1-8 The present invention provides the following technical solution:

[0031] Example 1 includes an injection molding machine 1, a frame 2 disposed beside the injection molding machine 1, a conveying device 3 disposed at the bottom of the frame 2, and a robotic arm 4 disposed beside the injection molding machine 1 for clamping a workpiece 7. The injection molding unloading mechanism also includes a correction mechanism 5 and an auxiliary abutment mechanism 6. The correction mechanism 5 is disposed at the top of the frame 2 and includes a mounting frame 51, a rotating part 52, and a clamping part 53. The mounting frame 51 is disposed at the top of the frame 2. The rotating part 52 is rotatably disposed at the bottom of the mounting frame 51 and is located at the top of the conveying device 3. The clamping part 53 is disposed at the bottom of the rotating part 52 and is used to clamp the offset metal part. The auxiliary abutment mechanism 6 is disposed at the top of the frame 2.

[0032] To address the problems existing in the prior art: during the metal part conveying and injection molding process, the metal part is prone to positional deviation during the conveying stage. This deviation necessitates additional position adjustment operations when the robotic arm 4 grips the metal part, thus delaying the injection molding process. It is important to note that the gripping part 53 is preferably a gripping cylinder, with a pair of gripping blocks slidably mounted on the bottom of the cylinder for gripping the metal part to be corrected. When the metal part is conveyed on the conveying device 3, it is in a deviated state. The gripping part 53 then grips the deviated metal part. After gripping, the rotating part 52 rotates, causing the gripping part 53 to rotate synchronously. Thus, when the gripping part 53 rotates, it can correct the position of the deviated metal part. This solves the problem of additional position adjustment required by the robotic arm 4 during metal part conveying deviation, which delays the injection molding process. It achieves the effect of quickly and accurately correcting the position of the metal part and ensuring efficient injection molding.

[0033] See Figures 5-7 The correction mechanism 5 also includes a first telescopic cylinder 54 and an output rod 55; the first telescopic cylinder 54 is disposed on the top of the mounting frame 51 and is located above the frame 2; the output rod 55 is disposed at the output end of the first telescopic cylinder 54, and the top of the rotating part 52 is rotatably connected to the bottom of the output rod 55. When the first telescopic cylinder 54 is activated, it can drive the output rod 55, the rotating part 52 and the clamping part 53 to move synchronously.

[0034] Specifically, in order to clamp and lift the metal part that needs to be corrected before placing it on the conveying device 3, the conveying device 3 stops when the misaligned metal part is below the clamping part 53. Then, the first telescopic cylinder 54 is activated. When the first telescopic cylinder 54 is activated, it can drive the output rod 55, the rotating part 52, and the clamping part 53 to rise or fall synchronously. This allows the metal part to be corrected to be clamped and lifted, and after correction, the output rod 55 drives the clamping part 53 to fall. This prevents the corrected metal part from shifting again due to the conveying of the conveying device 3 when it is placed on the conveying device 3 after correction.

[0035] See Figure 5 The correction mechanism 5 also includes a positioning frame 56 and a camera 57; the positioning frame 56 is located on the side of the mounting frame 51 and on the side of the rotating part 52; the camera 57 is located at the bottom of the positioning frame 56 and above the conveying device 3.

[0036] Specifically, in order to accurately detect the position and angle of each metal part's deviation, a controller connected to a camera 57 is provided on the side of the positioning frame 56. When a metal part moves with the conveyor 3 to below the camera 57, the camera 57 captures images of the metal part in real time and transmits the position, shape, and deviation of the metal part to the controller. Then, the controller controls the conveyor 3 to stop and causes the output rod 55 to descend and the clamping part 53 to correct the deviation of the metal part.

[0037] See Figures 4-7 The correction mechanism 5 also includes a toothed disc 58 and a gear 59. The toothed disc 58 is rotatably disposed at the bottom of the output rod 55 and is located outside the rotating part 52. The toothed disc 58 is fixedly connected to the rotating part 52. When the toothed disc 58 rotates, it can drive the rotating part 52 and the clamping part 53 to rotate synchronously.

[0038] Specifically, to enable the clamping part 53 to clamp and rotate the metal part, thereby correcting its position, when the clamping part 53 clamps the metal part and the rotating part 52 and the output rod 55 rise, the gear 59 rotates. The rotation of the gear 59 drives the meshing gear disk 58 to rotate. Since the gear disk 58 is fixedly connected to the outer side of the rotating part 52, and the top of the rotating part 52 is rotatably connected to the bottom of the output rod 55, the gear disk 58, the rotating part 52, and the clamping part 53 can rotate synchronously. This achieves position correction for clamping and rotating the metal part.

[0039] See Figure 7The correction mechanism 5 also includes a displacement part 591 and a rotary driver 592; the displacement part 591 is located on the outside of the output rod 55, and the top of the mounting bracket 51 is provided with a stroke groove for limiting the sliding of the displacement part 591; the rotary driver 592 is located on the side of the displacement part 591, and the output end of the rotary driver 592 is connected to the gear 59, so that when the rotary driver 592 is started, it can drive the gear 59 to rotate.

[0040] Specifically, to ensure that gear 59 can always mesh with gear disk 58, when output rod 55 rises or falls, it can synchronously drive displacement part 591, rotary driver 592 and gear 59 to move synchronously. Rotary driver 592 is preferably a servo motor. When rotary driver 592 is started, it can drive gear disk 58 to rotate. When gear 59 rotates, it can drive gear disk 58 to rotate.

[0041] See Figure 6 The auxiliary contact mechanism 6 includes a mounting plate 61, a pushing part 62, and an electric push rod 63. The mounting plate 61 is a pair and is respectively mounted on the top of the frame 2, and the pair of mounting plates 61 are located on the side of the mounting frame 51. The pushing part 62 is a pair and is respectively slidably mounted on the side of the mounting plate 61. The electric push rod 63 is a pair and is respectively mounted on the side of the mounting plate 61, and the output end of the pair of electric push rods 63 is respectively connected to the pair of pushing parts 62.

[0042] Specifically, in order to center the metal part on the conveying device 3, the electric push rod 63 is first activated. When the electric push rod 63 is activated, it can drive the pushing part 62 to move towards the clamping part 53 until the pushing part 62 contacts both sides of the metal part to be corrected and then stops. It should be noted that the pushing part 62 does not clamp the metal part, but only pushes the metal part under the clamping part 53 and then stops moving.

[0043] See Figure 6 The pushing part 62 has a cuboid structure and is located above the conveying device 3.

[0044] Specifically, the pushing part 62 is preferably a cuboid structure, which can extend the contact path with the metal part. The conveyed metal part is clamped and transferred by the robotic arm 4.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
