Description
Technical Field
[0001] This utility model belongs to the field of automotive processing technology, and more specifically, it relates to an automatic feeding mechanism for screw machines. Background Technology
[0002] Screws are one of the commonly used connecting parts in automobile assembly. Currently, automobile screws are generally arranged and transported by a conveyor frame, and then a robotic arm moves the corresponding screws to the assembly station for use by magnetic attraction. For example, patent application number CN202020813743.1 discloses an automatic feeding and lifting device for automobile screws, including a support frame. A support cross plate is fixedly installed on the upper end of the support frame. The support cross plate has a clearance groove. Two sets of slide rails are fixedly connected above the support cross plate. A slider is slidably connected above the slide rails. One end of the device is fixedly connected to a mounting base by bolts. A cylinder a is fixedly mounted on one end of the mounting base. The output end of one end of the cylinder a is fixedly connected to a slider. A cylinder b is fixedly connected above the slider. A vertical fixing plate is fixedly connected below the slider. A track is provided on one side of the vertical fixing plate. A sliding plate is slidably connected on the track. The lower output end of the cylinder b is fixedly connected to the upper part of the sliding plate by bolts. An electromagnet is fixedly mounted on the lower end of the sliding plate. This utility model facilitates the automatic feeding and lifting of screws, greatly improving the screw feeding efficiency.
[0003] In existing automotive screw loading mechanisms, the first screw is closely arranged with the other screws. This makes it easy for the robotic arm to simultaneously pick up the screws near the first screw when it magnetically attracts it, affecting subsequent assembly and use. Furthermore, the magnetism near the first screw is relatively weak, and the screws that are mistakenly picked up are prone to falling off when the robotic arm moves, resulting in screw loss. This mechanism is unstable and not very practical. Utility Model Content
[0004] This disclosure relates to an automatic feeding mechanism for a screw machine, which includes an isolation component. The isolation component can distribute the screw bodies arranged on the conveyor frame, that is, the screw body at the first position will have a certain distance from the other screw bodies, thereby avoiding the mechanical arm from affecting the other screw bodies when magnetically picking up the first screw body. This can effectively avoid the phenomenon of accidental picking. Moreover, the isolation component can release and pick up the screw bodies one by one, and the release distance can be freely adjusted. It can adapt to the conveying, picking up and feeding of screw bodies of different specifications, and has extremely high flexibility, adaptability, stability and practicality.

The conveying assembly includes a mounting frame and a conveyor frame. The mounting frame is fixedly mounted on a workbench, and the conveyor frame is fixedly mounted on the top of the mounting frame. The screw body is inserted into the interior of the conveyor frame. The mechanism also includes an isolation assembly consisting of a right-side mechanism and a left-side baffle. The right-side mechanism includes an electric push rod, a connecting plate, a positioning rod, and a right-side baffle. The electric push rod is fixedly mounted on the bottom right side of the conveyor frame, and the connecting plate is fixedly mounted on one end of the electric push rod. The positioning rod is rotatably connected to the side of the connecting plate, and the right-side baffle is inserted into the side of the connecting plate. The left-side baffle is inserted into the left side of the conveyor frame.
[0006] In at least some embodiments, the conveyor frame is a double-row frame design and is inclined, with the left baffle positioned lower than the right baffle.
[0007] In at least some embodiments, a track rod is provided at the bottom left side of the conveyor frame, and the cross-section of the track rod is a regular polygon, with the track rod inserted into the interior of the left side baffle.
[0008] In at least some embodiments, the track rod is provided with a blocking top spring on its exterior, and the two ends of the blocking top spring are respectively fixedly installed on the side of the track rod and the side of the left side plate.
[0009] In at least some embodiments, the side of the left baffle is provided with an abutment block, and the abutment block is located on the moving path of the right baffle.
[0010] In at least some embodiments, the positioning rod has threads on the outside of its body, and the positioning rod is screwed into the inside of the right side baffle through the threaded rod body.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] The isolation component can distribute the screws arranged on the conveyor frame, meaning that the first screw will be at a certain distance from the others.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.
[0022] As attached Figure 1 To be continued Figure 6 As shown:
[0023] Example 1: This utility model provides an automatic feeding mechanism for a screw machine, including a conveying component 1 and a screw body 4. The conveying component 1 includes a mounting frame 101 and a conveying frame 102. The mounting frame 101 is fixedly installed on the workbench, and the conveying frame 102 is fixedly installed on the top of the mounting frame 101. The screw body 4 is inserted into the interior of the conveying frame 102. It also includes an isolation component, which consists of a right-side mechanism 2 and a left-side baffle 3. The right-side mechanism 2 includes an electric push rod 201, a connecting plate 202, a positioning rod 203, and a right-side baffle 204. The electric push rod 201 is fixedly installed on the bottom right side of the conveying frame 102, and the connecting plate 202 is fixedly installed on one end of the push rod of the electric push rod 201. The positioning rod 203 is rotatably connected to the side of the connecting plate 202, and the right-side baffle 204 is inserted into the side of the connecting plate 202. The left-side baffle 3 is inserted into the left side of the conveying frame 102.
[0024] In this embodiment, the conveyor frame 102 is a double-row frame design and is inclined. The left baffle 3 is positioned lower than the right baffle 204. During use, the isolation component can distribute the screw bodies 4 arranged on the conveyor frame 102. When the isolation component is in the reset state (electric push rod 201 is in the extended state), the left baffle 3 will invade the bottom space of the conveyor frame 102 under the action of the blocking top spring 1022, thereby preventing the screw bodies 4 from slipping and positioning the screw bodies 4. This prevents the subsequent screw bodies 4 from being too close to the first screw body 4. At this time, the right baffle 204 will not invade the bottom space of the conveyor frame 102, so the screw bodies 4 can automatically fall and arrange under the action of the inclined conveyor frame 102. With this design, it is possible to effectively prevent the robotic arm from affecting the other screw bodies 4 when magnetically extracting the first screw body 4, effectively preventing the phenomenon of accidental extraction and ensuring stable use.
[0025] In this embodiment, a track rod 1021 is provided at the bottom left side of the conveyor frame 102, and the cross-section of the track rod 1021 is a regular polygon. The track rod 1021 is inserted into the interior of the left side baffle 3. This design ensures that the left side baffle 3 will not tilt or twist during movement, which could cause the device to jam and fail, and the device is stable in use.
[0026] In this embodiment, a blocking top spring 1022 is provided on the outside of the track rod 1021, and the two ends of the blocking top spring 1022 are respectively fixedly installed on the side of the track rod 1021 and the side of the left baffle 3. The side of the left baffle 3 is provided with an abutment block 301, and the abutment block 301 is located on the moving path of the right baffle 204. In use, the isolation assembly also has the function of releasing the screw body 4 one by one, thereby realizing the function of releasing the screw body 4 one by one for extraction and assembly. When the first screw body 4 is extracted, another screw body 4 can be released by retracting the electric push rod 201. In this process, the rule of blocking first and then releasing is followed to avoid releasing too many screw bodies 4. When the electric push rod 201 retracts, it will drive the right baffle 204 to move synchronously through the connecting plate 202, thereby blocking the screw body 4 that was originally in the third position. In this process, the left baffle 3 will not move. After the electric push rod 201 continues to retract, the right baffle 204 can drive the left baffle 3 to move synchronously and compress the blocking top spring 1022 by pressing against the abutment block 301. Thus, when the left baffle 3 moves, it can release the obstruction of the screw body 4 that was originally in the second position. After that, the screw body 4 that was originally in the second position will slide to the first position, thus completing the function of releasing the screw body 4 one by one. It is stable in use. When the screw body 4 that was originally in the second position is released, the isolation mechanism can be reset after the electric push rod 201 is extended. The isolation mechanism also follows the same rule of blocking first and then resetting when resetting. In the initial stage of the retraction of the electric push rod 201, under the action of the blocking top spring 1022, the left baffle 3 will first reset to restore the blocking state of the front of the screw body 4. After that, the right baffle 204 will move and reset to no longer block the subsequent screw body 4. It is stable in use.
[0027] In this embodiment, the positioning rod 203 has threads on its outer surface and is screwed into the inside of the right side baffle 204 via the thread. In use, the positioning rod 203 can adjust the distance between the left side baffle 3 and the right side baffle 204 along the long side of the conveyor frame 102, thereby adapting to the feeding of screw bodies 4 of different specifications. It is highly adaptable. When the positioning rod 203 is rotated, it can drive the right side baffle 204 to move along the long side of the conveyor frame 102 via the thread, thereby changing the distance between the left side baffle 3 and the right side baffle 204 along the long side of the conveyor frame 102. The adjustment is convenient and quick, and the use is flexible.
[0028] The specific usage and function of this embodiment are as follows:
[0029] In this invention, the screw bodies 4 are arranged and conveyed by the conveyor frame 102, and the first screw body 4 on the conveyor frame 102 is extracted and used by the robotic arm. The isolation component can distribute the screw bodies 4 arranged on the conveyor frame 102. When the isolation component is in the reset state (the electric push rod 201 is in the extended state), under the action of the blocking top spring 1022, the left baffle 3 will invade the bottom space of the conveyor frame 102, thereby preventing the screw body 4 from slipping and positioning the screw body 4. This prevents the subsequent screw body 4 from being too close to the first screw body 4. At this time, the right baffle 204 will not invade the bottom space of the conveyor frame 102, so that the screw body 4 can be used. The screws are automatically lowered and arranged under the action of the inclined conveyor frame 102. This design effectively avoids the robotic arm from affecting the other screws 4 when magnetically extracting the first screw body 4, thus preventing accidental extraction. The isolation component also has the function of releasing the screw bodies 4 one by one, thereby realizing the function of releasing the screw bodies 4 one by one for assembly and use. After the first screw body 4 is extracted, the retraction of the electric push rod 201 can release another screw body 4. In this process, the principle of blocking first and then releasing is followed to avoid releasing too many screw bodies 4. When the electric push rod 201 retracts, it will drive the right baffle 204 to move synchronously through the connecting plate 202, thereby... The screw body 4, originally in the third position, is blocked, and the left baffle 3 remains stationary during this process. Then, the electric push rod 201 continues to retract, and the right baffle 204, by pressing against the abutment block 301, drives the left baffle 3 to move synchronously and compress the blocking top spring 1022. Thus, the left baffle 3 releases its obstruction of the screw body 4, which was originally in the second position. The screw body 4 then slides to the first position, completing the function of releasing the screw bodies 4 one by one. Once the screw body 4 in the second position is released, the isolation mechanism resets after the electric push rod 201 extends. The reset of the isolation mechanism also follows the principle of blocking first and then resetting. According to the pattern, during the initial retraction of the electric push rod 201, under the action of the blocking top spring 1022, the left baffle 3 will first reset to restore its blocking state on the front side of the screw body 4. After that, the right baffle 204 will move and reset to no longer block the subsequent screw body 4. The positioning rod 203 can adjust the distance between the left baffle 3 and the right baffle 204 in the long side direction of the conveyor frame 102, so as to adapt to the conveying and feeding of screw bodies 4 of different specifications. It is highly adaptable. When the positioning rod 203 is rotated, the positioning rod 203 can drive the right baffle 204 to move in the long side direction of the conveyor frame 102 through the rod thread, thereby changing the distance between the left baffle 3 and the right baffle 204 in the long side direction of the conveyor frame 102.
