Description

Technical Field

[0001] This utility model relates to the field of optical fiber box assembly technology, and in particular to an automatic feeding and screw-locking mechanism. Background Technology

[0002] Automatic screw fastening machines are typical non-standard automated equipment. They use various electric and pneumatic components to automatically feed, tighten, and inspect screws. The equipment simplifies the screw fastening process, reducing the number of workers and minimizing the adverse effects of human error.

[0003] like Figure 1 The fiber optic box bracket shown requires adjustment of its screw holes to align with the internal positions of the fiber optic box during installation. Currently, this is typically done semi-automatically with manual screw fastening, which impacts operational efficiency. Manual adjustment is time-consuming and poses significant safety hazards. Therefore, this invention proposes a feeding mechanism for an automatic screw fastening machine to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide an automatic feeding and screw-locking mechanism. This utility model can obviously realize fully automatic operation of material picking, rotation, unloading and screw locking, improve production efficiency and work quality, and avoid the safety hazards of manual adjustment.

[0005] To achieve the above objectives, this utility model provides an automatic screw feeding and locking mechanism, comprising:

[0006] A base on which a slide module is fixedly mounted;

[0007] An automatic feeding assembly linked with the slide module includes a first lifting assembly and a rotating assembly linked with the first lifting assembly. The rotating assembly is connected to a workpiece gripper, and the rotating assembly drives the workpiece gripper to rotate by an angle.

[0008] An automatic screw-locking assembly linked to the slide module, the automatic screw-locking assembly including a second lifting assembly and an automatic electric screwdriver connected to the second lifting assembly;

[0009] The automatic feeding assembly and the automatic screw fastening assembly are arranged facing each other, and the slide module drives the automatic feeding assembly and the automatic screw fastening assembly to move.

[0010] Furthermore, the slide module is equipped with a first slider, a second slider, and two sets of driving linear motors. The first slider and the second slider are linked with different driving linear motors to achieve independent operation. By using two sets of linear motors to independently drive the first slider and the second slider, the two sliders can move independently, which facilitates the automatic feeding component to pick up materials. At the same time, the automatic screw-locking component can lock screws on the loaded workpieces, thereby achieving uninterrupted continuous production.

[0011] Furthermore, a first slide rail is provided on the side of the base away from the slide module, and a first sliding seat and a second sliding seat are also included. One side of the first sliding seat is slidably connected to the first slide rail, and the other side of the first sliding seat is fixedly connected to the first slider. The automatic feeding component is fixedly connected to the first sliding seat. One side of the second sliding seat is slidably connected to the first slide rail, and the other side of the second sliding seat is fixedly connected to the second slider. The automatic screw-locking component is fixedly connected to the second sliding seat. This forms a beam-type structure for installing the automatic feeding component and the automatic screw-locking component, which not only enables synchronous and coordinated operation of the two components, but also provides a stable support base, ensuring the stability of the operation of the two components and improving product efficiency and quality.

[0012] Furthermore, the first lifting assembly includes a first lifting main seat, a first lifting cylinder and a second slide rail fixed to the first lifting main seat, a fifth slider on the second slide rail, and a first lifting support connected to the fifth slider. The first lifting cylinder is linked with the first lifting support. This assembly is used to drive the lifting of the workpiece gripper, coordinating the gripping and lowering of the workpiece.

[0013] Furthermore, two sets of rotating components are fixedly connected to the first lifting support. These two sets of rotating components are evenly distributed on the first lifting support. Each set of rotating components includes a first rotary motor fixed to the first lifting support. The first rotary motor is connected to a rotary joint, which is connected to the workpiece gripper. This dual-station operation using dual rotating components allows for the gripping of two workpieces at a time for angle adjustment and transfer locking, effectively improving work efficiency.

[0014] Furthermore, a first sensor is installed below the first lifting support. The first sensor is used to monitor the rotation state of the workpiece, ensuring that it rotates to a suitable locking angle and improving the quality of material feeding.

[0015] Furthermore, the second lifting assembly includes a second lifting base and a third lifting cylinder and a third slide rail fixedly connected to the second lifting base. A third slider and a fourth slider are provided on the third slide rail, and the automatic electric screwdriver is fixedly connected to the third slider. This enables the automatic electric screwdriver to be lifted and lowered for tightening screws and then detached from the product after completion.

[0016] Furthermore, the second lifting assembly also includes a fourth lifting cylinder fixed to the second lifting seat, a fourth slider is provided on the third slide rail, and a screw chuck that works in conjunction with the automatic electric screwdriver is fixed to the fourth slider. The screw chuck is coaxially arranged with the automatic electric screwdriver. The screw chuck significantly improves the accuracy and efficiency of screwing, and effectively avoids the risk of screw misalignment or falling off.

[0017] Furthermore, a second sensor is provided on one side of the second lifting seat, and a third sensor is provided on one side of the screw chuck. The second sensor is used to detect whether the screw is tightened in place, while the third sensor monitors whether the screw is air-blown into place.

[0018] Furthermore, a reinforcing member with an inverted triangular shape is provided on the other side of the second lifting seat to improve its stability.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This utility model employs a sliding table module that can drive the first and second sliders to move independently. The first and second sliders are respectively used to connect the automatic feeding component and the automatic screw fastening component, enabling the automatic feeding component and the automatic screw fastening component to move independently. This allows for uninterrupted and coordinated feeding and screw fastening of the automatic feeding component and the automatic screw fastening component, thus improving the overall work efficiency.

[0021] The automatic feeding assembly of this utility model can lift and pick up materials in real time and adjust the angle of the workpiece. In particular, a first sensor is set up to monitor the rotation angle of the workpiece to ensure that it rotates to the specified direction and ensures the orderly progress of the subsequent screw-locking process in conjunction with the automatic screw-locking assembly. Thus, the fully automated operation of material picking, rotation, feeding and screw-locking is realized, replacing manual operation and improving production efficiency and work quality.

Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0033] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second", such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0034] like Figures 1 to 6 This utility model discloses an automatic feeding and screw-locking mechanism, including a base 1, an automatic feeding assembly 3 linked with a slide module 2, and an automatic screw-locking assembly 4.

[0035] like Figure 1 As shown, a slide module 2 is fixedly mounted on the base 1. This slide module 2 is a commercially available conventional slide module 2 (also known as a linear module). In this embodiment, the automatic feeding component 3 and the automatic screw fastening component 4 are arranged facing each other. The slide module 2 drives the automatic feeding component 3 and the automatic screw fastening component 4 to move. To realize the movement of the automatic feeding component 3 and the automatic screw fastening component 4, a first slider 21, a second slider 22, and two sets of drive linear motors are provided on the slide module 2. In this embodiment, the drive linear motors of the slide module 2 are embedded double-acting linear motors (not shown in the figure). The first slider 21 and the second slider 22 are linked with different drive linear motors. By using two sets of drive linear motors to drive the first slider 21 and the second slider 22 respectively, not only can the independent operation of the first slider 21 and the second slider 22 be realized, but also the synchronous and coordinated operation of the two first sliders 21 and the second slider 22 can be controlled to improve the overall coordination and efficiency of the operation. The appropriate method can be selected according to the actual situation.

[0036] The base 1 is provided with a first slide rail 23 on the side away from the slide module 2, and also includes a first slide seat 24 and a second slide seat 25. One side of the first slide seat 24 is slidably connected to the first slide rail 23, and the other side of the first slide seat 24 is fixedly connected to the first slider 21. The automatic feeding assembly 3 is fixedly connected to the first slide seat 24. One side of the second slide seat 25 is slidably connected to the first slide rail 23, and the other side of the second slide seat 25 is fixedly connected to the second slider 22. The automatic screw locking assembly 4 is fixedly connected to the second slide seat 25.

[0037] like Figure 2 As shown, the automatic feeding assembly 3 includes a first lifting assembly 31 and a rotating assembly 32 linked to the first lifting assembly 31. The rotating assembly 32 is connected to a workpiece gripper 33, and the rotating assembly 32 drives the workpiece gripper 33 to rotate by an angle. The first lifting assembly 31 is used to drive the rotating assembly 32 to lift and lower, facilitating the gripping of the workpiece. In this embodiment, the first lifting assembly 31 includes a first lifting main seat 311 and a first lifting cylinder 312 and a second slide rail 313 fixed to the first lifting main seat 311. A fifth slider 316 is provided on the second slide rail 313, and a first lifting support 314 is connected to the fifth slider 316. Figure 3As shown, outwardly protruding positioning portions 3161 are formed on both sides of the fifth slider 316. A limiting seat 317 is connected to the first lifting support 314. A limiting column 318 that cooperates with the positioning portion 3161 is provided on the limiting seat 317. The height of the limiting column 318 restricts the lifting position of the rotating component 32. The first lifting cylinder 312 is linked with the first lifting support 314. Preferably, two sets of rotating components 32 are fixedly connected to the first lifting support 314. The two sets of rotating components 32 are evenly distributed on the first lifting support 314. Each set of rotating components 32 includes a first rotary motor 321 fixedly connected to the first lifting support 314. The first rotary motor 321 is connected to a rotary joint 322. The rotary joint 322 is connected to the workpiece gripper 33. Notably, the rotary joint 322 is a pneumatic rotary joint 322, and the workpiece gripper 33 is a vacuum suction cup. Using the rotary joint 322 ensures unobstructed airflow to the workpiece gripper 33 and prevents pipe entanglement. Figure 3 As shown, a recessed mounting groove 3221 is formed at the bottom of the rotary joint 322. The workpiece gripper 33 is provided with a gripping main seat 331, which is embedded in the mounting groove 3221 and fixed by screws. The embedded connection structure makes the rotary joint 322 drive the workpiece gripper 33 to rotate more sensitively and prevents misalignment, thus improving the rotation accuracy. Furthermore, a first sensor 315 is provided below the first lifting support 314. The first sensor 315 is used to monitor the rotation status of the workpiece to ensure that it rotates to the appropriate locking angle, thereby improving the quality of loading.

[0038] like Figure 4 As shown, the automatic screw fastening assembly 4 includes a second lifting assembly 41 and an automatic electric screwdriver 42 connected to the second lifting assembly 41. The second lifting assembly 41 includes a second lifting base 411 and a third lifting cylinder 412 and a third slide rail 413 fixed to the second lifting base 411. A third slider 414 and a fourth slider 415 are provided on the third slide rail 413. The automatic electric screwdriver 42 is fixed to the third slider 414, thereby realizing the lifting of the automatic electric screwdriver 42 for screw fastening operations and detachment from the product after completion.

[0039] To facilitate the operation of the automatic electric screwdriver 42, in this embodiment, the second lifting assembly 41 further includes a fourth lifting cylinder 410 fixedly connected to the second lifting base 411. A fourth slider 415 is provided on the third slide rail 413, and a screw chuck 417 that works in conjunction with the automatic electric screwdriver 42 is fixedly connected to the fourth slider 415. The screw chuck 417 is coaxially arranged with the automatic electric screwdriver 42. The screw chuck 417 significantly improves the accuracy and efficiency of screwing, and effectively avoids the risk of screw misalignment or falling off.

[0040] Preferably, a second sensor 416 is provided on one side of the second lifting seat 411, and a third sensor 418 is installed on one side of the screw chuck 417. The second sensor 416 is used to detect whether the screw is tightened in place, and the third sensor 418 monitors whether the screw is blown into place by air.

[0041] like Figure 1 As shown, the second lifting seat 411 is directly fixed to the front end face of the second sliding seat 25, and the force-bearing area is small. Uneven force distribution can easily lead to the second lifting seat 411 detaching. In this embodiment, the position is as follows... Figure 2 As shown, a reinforcing member 419 with an inverted triangular shape is provided on the other side of the second lifting seat 411. One side of the reinforcing member 419 is fixedly connected to the second lifting seat 411, and the other end is fixedly connected to the upper end face of the second sliding seat 25, thereby forming a good force distribution and improving the stability of the second lifting seat 411.

[0042] Brief description of the working principle of this utility model: This utility model uses a sliding table module 2 to drive the automatic feeding component 3 and the automatic screw-locking component 4 to move independently. When needed, they can be controlled to move forward or backward synchronously. The automatic feeding component 3 is set on the first sliding seat 24, and the automatic screw-locking component 4 is set on the second sliding seat 25. A gap is set between the first sliding seat 24 and the second sliding seat 25 so that the automatic feeding component 3 and the automatic screw-locking component 4 have enough space to coordinate their operation when moving back and forth. When the operation starts, the sliding table module 2 starts, driving the automatic feeding component 3. At this time, there is no workpiece on the workstation, so the automatic screw-locking component 4 does not work for the first time. The automatic feeding component 3 moves to the front, where it cooperates with other automatic feeding mechanisms to assist in feeding. When the automatic feeding component 3 reaches the feeding workstation, the first lifting cylinder 312 starts, driving the workpiece gripper 33 to move down. The workpiece gripper 33 starts to suck up the workpiece, and then the first lifting cylinder 312 resets. Then the first rotary motor 321 starts, driving the workpiece gripper 33 to rotate. The first sensor The device 315 monitors the rotation of the workpiece in real time. When the rotation reaches the required angle, the first rotary motor 321 stops, then the slide module 2 starts, the first lifting component 31 retracts back to its initial position, and below the initial position is the workpiece mounting mechanism. Then the first lifting cylinder 312 starts, and the workpiece gripper 33 moves down. When the workpiece reaches the assembly station, the workpiece gripper 33 releases the workpiece, and then the first lifting cylinder 312 resets. Then the automatic feeding component 3 continues to repeat the above actions to pick up the workpiece. At the same time, the drive linear motor on the other side starts and drives the automatic screw fastening component 4 to move forward to above the workpiece. The third lifting cylinder 412 and the fourth lifting cylinder 410 start synchronously and drive the automatic electric screwdriver 42 and the screw chuck 417 to move down. The screw chuck 417 presses the workpiece, the automatic electric screwdriver 42 starts, and the third lifting cylinder 412 continues to move down until the screw fastening operation is completed and then resets. At this time, the automatic feeding component 3 arrives with the second workpiece. By repeating this operation, the fully automatic feeding, angle adjustment, and screw fastening assembly actions can be achieved.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
