Description

TECHNICAL FIELD

[0002] In the field of automobile parts production, rain plugs, as key components for sealing the vehicle body, need to be matched with different specifications (such as different diameters and heights) according to the differences in vehicle models. The distribution accuracy and efficiency directly affect the smoothness of subsequent assembly processes.

[0003] Traditional rain plug distribution relies on manual sorting or single mechanical structure, with low specification determination accuracy. When manually sorting, the operator needs to distinguish the rain plug specifications based on vision and experience. For rain plugs with subtle differences in form (such as small differences in diameter), the misidentification rate is relatively high, and the sorting amount per hour for a single person is also small, making it difficult to meet the needs of mass production. Some mechanical distribution devices use a single sensor for detection, which is easily affected by the surface reflection and stains of the rain plug, making it difficult to accurately capture the specification differences. The distribution qualification rate needs to be improved, leading to material mismatch during subsequent assembly and a certain rate of rework.

[0028] Figures 1 to 7 ​​​​​The utility model provides a rain cover distribution switching device for automobile, which comprises a bottom seat 1, one end of the bottom seat 1 is provided with a conveying seat 2, the conveying seat 2 is provided with a feeding belt assembly 21, the other end of the bottom seat 1 is provided with a switching seat assembly, the switching seat assembly is composed of a switching bottom seat 3 and a combined switching seat 31, the switching bottom seat 3 is connected with a main transmission belt assembly 32, and the combined switching seat 31 is connected with a vice transmission belt assembly 33; an automatic detection mechanism, the automatic detection mechanism comprises a top cross beam 4, the top cross beam 4 is fixedly connected with the bottom seat 1, both ends of the top cross beam 4 are provided with front supports 41, one end of the two front supports 41 is rotatably connected with a main shaft 42, the lower end of the two main shafts 42 is fixedly connected with a light weight push piece 43, the two light weight push pieces 43 are symmetrically arranged in a spread shape, the two front supports 41 are fixedly connected with right angle stabilizing frames 44, the two main shafts 42 and the two right angle stabilizing frames 44 are connected with torsional springs 45, and the two front supports 41 are provided with distinguishing assemblies.

[0029] In the specific implementation process, as shown in Figure 2 and Figure 3 the lower end of the two right angle stabilizing frames 44 is provided with a rotating opening, the two main shafts 42 are rotatably connected with the two right angle stabilizing frames 44, the distinguishing assembly comprises an angle sensor 5, the angle sensor 5 is fixedly installed on the right angle stabilizing frame 44, the angle sensor 5 is provided with a clamping detection ring 51, and the upper end of the main shaft 42 is fixedly connected with the clamping detection ring 51.

[0030] It should be noted that the rain cover is in contact with the two light weight push pieces 43 oppositely arranged at the front support 41, due to the different shapes and sizes of the rain cover, the pushing force on the light weight push piece 43 is different, which can make the two light weight push pieces 43 drive the two main shafts 42 to open and rotate at different angles (for example, the opening angle of the large size rain cover is greater than or equal to 30 degrees, and the opening angle of the small size rain cover is less than or equal to 15 degrees), the two torsional springs 45 are deformed accordingly, the clamping detection ring 51 fixedly connected with the main shaft 42 rotates synchronously with the main shaft 42, so that the angle sensor 5 (prior art, which can be directly installed on the bottom seat 1) on the right angle stabilizing frame 44 can capture the rotating angle in real time and feed back the data to the controller (prior art), so that the controller can determine the size of the rain cover according to the feedback;

[0031] The light weight push piece 43 is made of ABS engineering plastic material, and the weight can be controlled to be lighter, so that it can rotate sensitively under the action of the rain cover pushing force, and has good impact resistance;

[0032] The two light weight push pieces 43 are initially arranged at an eight-shaped angle, so that rain covers of different sizes can be in contact with them and opened at corresponding angles;

[0033] There is no relative sliding between the clamping detection ring 51 and the main shaft 42, so that the rotating angle captured by the angle sensor 5 is completely consistent with the actual rotating angle of the main shaft 42.

[0034] ReferenceFigure 1 And Figure 5 As shown in FIG. 1 and FIG. 2, the switching base 3 is provided with an automatic switching mechanism between the bottom base 1, the automatic switching mechanism includes a plurality of side beams 6, the plurality of side beams 6 are all fixedly connected with the other end side wall of the bottom base 1, the plurality of side beams 6 are symmetrically arranged in pairs, and a vertical rod 61 is fixedly connected between the plurality of side beams 6. A plurality of side blocks 62 are symmetrically arranged in pairs on the side wall of the switching base 3, a plurality of limiting openings are arranged in the plurality of side blocks 62, the plurality of side blocks 62 are respectively connected with the plurality of vertical rods 61 in a sliding manner, a plurality of reset springs 63 are arranged on the plurality of vertical rods 61 in a sleeving manner, and a plurality of pressing assemblies are arranged between the plurality of side blocks 62 and the plurality of side beams 6.

[0035] It should be noted that the side block 62 slides downward along the vertical rod 61, so that the plurality of reset springs 63 are all elastically deformed, so as to drive the switching base 3 to descend, so that the combined switching base 31 is kept in alignment with the conveying base 2, and the sub-transmission belt assembly 33 is aligned with the feeding belt assembly 21, so that the switching of conveying is stably and quickly completed.

[0036] The symmetric arrangement of the side beams 6 in pairs can ensure that the switching base 3 is stably supported without deformation, so that the switching base 3 remains horizontal during the lifting process, and the inclination is avoided to cause the transmission belt to be deviated during alignment.

[0037] Referring to FIG. 1 and FIG. 2, the upper ends of the plurality of reset springs 63 are connected with the plurality of side blocks 62, and the lower ends of the plurality of reset springs 63 are connected with the lower ends of the plurality of side beams 6. Figure 5 Referring to FIG. 1 and FIG. 2, the lower ends of the plurality of reset springs 63 are connected with the lower ends of the plurality of side beams 6.

[0038] Figure 4 And Figure 5 As shown in FIG. 1 and FIG. 2, the lower ends of the plurality of reset springs 63 are connected with the lower ends of the plurality of side beams 6.

[0039] It should be noted that if the second specification is used, the upper electromagnet 65 on the plurality of side beams 6 is energized to generate magnetism, which generates repulsive force with the embedded magnetic block 64 (same magnetic pole) embedded in the corresponding side block 62, so as to push the side block 62 to slide downward along the vertical rod 61.

[0040] The upper electromagnet 65 is a direct-current electromagnet with a rated voltage of 24V. After being energized, the repulsive force generated is sufficient to overcome the elastic force of the reset spring 63 and the weight of the switching base 3, so as to push the side block 62 to slide downward quickly, and the track switching time is controlled within a few seconds.

[0041] Referring to FIG. 1 and FIG. 2, the upper ends of the plurality of reset springs 63 are connected with the plurality of side blocks 62, and the lower ends of the plurality of reset springs 63 are connected with the lower ends of the plurality of side beams 6. Figure 2 Figure 6 ​​As shown, the bottom seat 1 is provided with a cavity, and two through holes are symmetrically arranged on the cavity wall at one end, two locking clamping rods 7 are slidably connected in the through holes, the side walls of the switching seat 3 and the combined switching seat 31 are symmetrically provided with sockets, one end of the two locking clamping rods 7 is connected with a horizontal plate 71, a bottom supporting plate 72 is fixedly connected in the cavity, two limiting protrusions 73 are symmetrically arranged on the bottom supporting plate 72, limiting clamping grooves are arranged at both ends of the horizontal plate 71, the horizontal plate 71 is slidably connected with the two limiting protrusions 73, a middle pipe 74 is fixedly connected at one end of the bottom supporting plate 72, a rear frame 75 is fixedly connected at the rear end position of the bottom supporting plate 72, and an ejection assembly is arranged in the middle pipe 74.

[0042] It should be noted that when the track switching is completed, the horizontal plate 71 moves along the limiting protrusions 73 of the bottom supporting plate 72, so that the two locking clamping rods 7 extend from the through holes and are clamped into the corresponding clamping grooves of the switching seat 3, to realize the stability of the conveying after the transmission switching is completed.

[0043] Reference Figure 6 and Figure 7 As shown, the ejection assembly includes a sliding rod 8, the sliding rod 8 is slidably connected with the pipe wall of the middle pipe 74, a fixed disc 81 is fixedly connected on the sliding rod 8, one end of the sliding rod 8 is fixedly connected with the middle position of the horizontal plate 71, an internal spring 82 is sleeved on the sliding rod 8, the other end of the sliding rod 8 is fixedly connected with a magnetic disc 83, and a rear electromagnet 84 is installed and connected on the rear frame 75.

[0044] It should be noted that the rear electromagnet 84 on the rear frame 75 is energized to generate magnetism under the instruction of the controller, which generates repulsion with the magnetic disc 83 (same magnetic pole) at the end of the sliding rod 8, pushes the sliding rod 8 to slide along the middle pipe 74, and drives the horizontal plate 71 to stably move along the limiting protrusions 73 of the bottom supporting plate 72;

[0045] The fixed disc 81 is attached to the inner wall of the middle pipe 74, which can prevent the sliding rod 8 from tilting when sliding;

[0046] The internal spring 82 is a reset push spring, which pushes the fixed disc 81 to reset the sliding rod 8 when the rear electromagnet 84 is de-energized, so that the locking clamping rod 7 is quickly retracted;

[0047] The magnetic disc 83 has the same magnetic pole area as the rear electromagnet 84, which ensures that the repulsion generated by the two acts uniformly on the sliding rod 8.

[0048] Reference Figure 7As shown, the fixed disc 81 is arranged in the middle tube 74, one end of the built-in spring 82 is connected with the fixed disc 81, the other end of the built-in spring 82 is connected with the inner wall of the middle tube 74, the rear electromagnet 84 is the same as the magnetic pole of the magnetic disc 83, two arc-shaped tabs 9 are symmetrically arranged on the side wall of the fixed disc 81, two built-in limiting grooves 91 are symmetrically arranged on the inner wall of the middle tube 74, and the two arc-shaped tabs 9 are respectively connected with the two built-in limiting grooves 91 in sliding mode.

[0049] It should be noted that the arc-shaped tabs 9 on the fixed disc 81 slide along the built-in limiting grooves 91 of the middle tube 74 to limit the sliding of the sliding rod 8, ensure the accurate clamping of the locking clamping rod 7, avoid the shaking of the switching base 3 during track conveying, and ensure the stable conveying of the rain cover.

[0050] The length of the built-in limiting groove 91 matches the extension length of the locking clamping rod 7, the sliding stroke of the fixed disc 81 is limited, and the locking clamping rod 7 is prevented from being damaged due to excessive extension.

[0051] The cooperation of the arc-shaped tabs 9 and the built-in limiting grooves 91 further improves the stability of the sliding of the sliding rod 8, and ensures that the locking clamping rod 7 is accurately clamped into the socket of the switching base 3.

[0052] The working principle of the rain cover distribution switching device for an automobile provided by the application is as follows: when the rain cover to be distributed is conveyed to the lower side of the top cross beam 4 by the feeding belt assembly 21 of the conveying seat 2, the rain cover will contact the two oppositely arranged light push plates 43 at the front frame 41, due to the different shapes and sizes of the rain cover, the pushing force on the light push plates 43 is different, which will make the two light push plates 43 drive the two main shafts 42 to open and rotate at different angles, the torsional spring 45 will be deformed, the clamping detection ring 51 fixedly connected with the main shaft 42 will rotate synchronously with the main shaft 42, so that the angle sensor 5 (prior art) on the right-angle stabilizing frame 44 can capture the rotation angle in real time and feed back the data to the controller (prior art), so that the controller can determine the size of the rain cover according to the feedback.

[0053] The rear controller automatically switches the mechanism according to the rain cover specification instruction. If it is the first specification, the original state is maintained, so that the main transmission belt assembly 32 on the switching base 3 and the feeding belt assembly 21 are kept in alignment, so that the material can be automatically transported; if it is the second specification, the upper electromagnet 65 on the plurality of side beams 6 is controlled to generate magnetism, which generates repulsive force with the embedded magnetic block 64 (same magnetic pole) in the corresponding side block 62, pushes the side block 62 to slide downward along the vertical rod 61, so that the plurality of reset springs 63 are elastically deformed, to drive the switching base 3 to be lowered, so that the combined switching seat 31 is kept in alignment with the conveying seat 2, and at the same time, the vice transmission belt assembly 33 is aligned with the feeding belt assembly 21, and the rain cover directly enters the vice transmission belt assembly 33 for transportation; if it is the third specification, the controller instructs the vice transmission belt assembly 33 to reverse, the rain cover enters the reverse conveying track, and the difference of the three tracks is realized.

[0054] If it is necessary to restore to the first specification, only the upper electromagnet 65 needs to be controlled to be de-energized, the reset spring 63 is bounced to drive the switching base 3 to be raised, the main transmission belt assembly 32 is restored to be aligned with the feeding belt assembly 21, and the rain cover enters the main transmission belt assembly 32 to restore the initial forward conveying.

[0055] When the track switching is completed, the controller instructs the rear electromagnet 84 on the rear frame 75 to be energized to generate magnetism, which generates repulsive force with the magnetic disc 83 (same magnetic pole) at the end of the slide rod 8, pushes the slide rod 8 to slide along the middle tube 74, drives the horizontal plate 71 to move along the limiting convex strip 73 of the bottom supporting plate 72, so that the two locking clamping rods 7 are stretched out from the through hole and clamped into the corresponding clamping groove of the switching base 3, to realize the stability of conveying after the transmission switching is completed; at the same time, the arc-shaped tab 9 on the fixed disc 81 slides along the built-in limiting groove 91 of the middle tube 74, to limit the sliding of the slide rod 8, to ensure that the locking clamping rod 7 is accurately clamped, to avoid the switching base 3 from shaking during track conveying, and to ensure that the rain cover is stably conveyed.
