Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a sealing ring material picking and supporting device. Background Technology

[0002] To improve the sealing of mobile phone buttons, sealing rings are typically installed on the buttons to enhance their sealing performance. During the assembly of the sealing ring, tools are usually used manually to expand the sealing ring, increasing its inner diameter. This makes it easier to fit the sealing ring into the installation position, and the sealing ring itself is then fixed in place by its restoring force.

[0003] The sealing rings installed on mobile phone buttons are made of small materials, which are easily dropped when handled manually or by mechanical claws, resulting in significant losses. On the other hand, it is difficult to control the expansion of the sealing ring, which can easily damage it. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sealing ring material taking and supporting device.

[0005] The technical solution of this utility model is:

[0006] A sealing ring picking and supporting device, characterized in that it includes a mechanical frame, on which a drive moving module is provided, and a gripper assembly is connected to the drive moving module; the drive moving module drives the gripper assembly to move closer to or away from the supporting mechanism, or drives the picking gripper assembly to move up and down in the vertical direction;

When the two elastic elements are in their natural state, the gap between each material support is smaller than the outer diameter of the sealing ring in its natural state.

[0009] Furthermore, the floating base is provided with a material throwing through hole along its central axis, and each of the material support gaps is located above the diameter of the material throwing through hole.

[0010] Furthermore, each of the aforementioned support stations is equipped with a lifting mechanism located below the support plate; the lower end of each support plate is connected to the drive end of the lifting mechanism, and the lifting mechanism drives the two support plates to move closer or further apart.

[0017] Furthermore, the gripper assembly includes a gripper frame and a plurality of picking pins placed on the gripper frame; the number of picking pins is the same as the number of material support gaps; each picking pin is cylindrical and has a tapered portion at its top.

[0018] Furthermore, each material support station is equipped with an optical fiber sensor located above the material support plate to detect whether the sealing ring on the material pick-up needle is in place or whether the material has fallen off.

[0019] The beneficial technical effects of this utility model are:

[0020] Firstly, the material-taking needle in the gripper assembly of this utility model is not prone to dropping material when taking the sealing ring, and the expansion size of the sealing ring is highly reproducible, making it less likely to damage the sealing ring.

[0029] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0030] like Figures 1-6 As shown, this utility model provides a sealing ring picking and supporting device, which includes a drive moving module mounted on a mechanical frame 100 and a gripper assembly 200 connected to the drive moving module. After the gripper assembly 200 picks up the sealing ring 000 from the sealing ring feeding table, the drive moving module drives the gripper assembly 200 to move to the supporting mechanism 300. Then, the drive moving module drives the gripper assembly 200 to move up and down in the supporting gap 3021 in the supporting mechanism 300 to complete the supporting action of the sealing ring 000.

[0031] The drive movement module includes an X-axis linear movement module and a Z-axis linear movement module connected to the X-axis linear movement module. The X-axis linear movement module includes an X-axis servo motor 101 mounted on the mechanical frame 100 and an X-axis guide rail 102 arranged parallel to the drive end of the X-axis servo motor 101. One side of the slider is slidably connected to the drive end of the X-axis servo motor 101 and the X-axis guide rail 102.

[0032] The Z-axis linear motion module includes a Z-axis backplate 106, a Z-axis servo motor 103, and a Z-axis guide rail 104.

[0033] The Z-axis backplate 106 is connected to a slider on the X-axis guide rail 102. The Z-axis servo motor 103 is mounted on the Z-axis backplate 106, and the Z-axis guide rail 104 is mounted on the Z-axis backplate 106 and parallel to the drive end of the Z-axis servo motor 103. One side of the slider is slidably connected to the drive end of the Z-axis servo motor 103 and the Z-axis guide rail 104, and the other side is connected to a gripper slide plate 105. The gripper assembly 200 is fixedly attached to the gripper slide plate 105.

[0034] The X-axis linear motion module drives the gripper assembly 200 to approach the sealing ring feeding platform (not shown) and the material support mechanism along the X-axis direction, while the Z-axis linear motion module drives the gripper assembly 200 to rise and fall along the vertical direction perpendicular to the X-axis.

[0035] The gripper assembly 200 includes a gripper frame 201 and a plurality of pick-up pins 202 fixed to the gripper frame 201. The number of pick-up pins 202 can be set according to actual production needs. In this invention, two pick-up pins 202 are arranged in parallel at intervals.

[0036] Each picking needle 202 is cylindrical, with a diameter larger than that of the sealing ring 000 in its natural state. Each picking needle 202 has a tapered portion 2021 at its tip, designed to facilitate the insertion of the sealing ring 000. The size of the tapered portion 2021 is compatible with the inner diameter of the sealing ring 000 in its natural state. To ensure consistent expansion of the sealing ring 000 during each expansion, the intersection of the tapered portion 2021 and the cylindrical portion of the picking needle 202 is designated as a support stop portion 2022. The diameter of the support stop portion 2022 is larger than that of the sealing ring 000 in its natural state.

[0037] The material support mechanism 300 is located within the operating path of the gripper assembly 200.

[0038] The material support mechanism 300 includes a floating base 301. To provide the stroke for the material picking needle 202 to descend and for subsequent material throwing, the floating base 301 is provided with a material throwing through hole 304 along its central axis.

[0039] The floating base 301 has the same number of support stations as the material picking needles 202. The floating base 301 of this invention has two support stations. The two support stations are arranged parallel to each other at intervals.

[0040] Each material support station has a straight slide rail 400 on its opposite side. The straight slide rail 400 is set horizontally and perpendicular to the X-axis direction.

[0041] Each material support station is equipped with two material support plates 302. Each material support plate 302 consists of a material support connecting plate 3023 and a material support plate 3024. Each material support connecting plate 3023 has a "7"-shaped cross-section, with its top surface connected to the material support plate 3024 and its bottom surface slidably connected to a linear guide rail 400. Each opposite side of each material support connecting plate 3023 is connected to an elastic element 303. One end of each elastic element 303 is fixed to the material support connecting plate, and the other end is fixed to the side of the floating base 301. The two material support plates 3024 at each material support station have a left-right mirror symmetrical structure, each being a "7"-shaped plate. Each adjacent side of the upper end of each material support plate 3024 has a semi-circular notch 3025, and the two opposite notches 3025 form a material support gap 3021. Each material support gap 3021 is located above the diameter range of the throwing through hole 304. When the two elastic elements 303 are in their natural state, the diameter of each support gap 3021 is smaller than the outer diameter of the sealing ring 000 in its natural state.

[0042] The elastic element 303 of this utility model is a spring.

[0043] When the pick-up needle 202 moves with the X-axis linear moving module to above the support gap 3021, the sealing ring 000 on the conical part 2021 abuts against the upper surface of the two notches 3025. The pick-up needle 202 continues to descend along the Z-axis linear moving module along the support gap 3021, so that the sealing ring 000 on the conical part 2021 rises to the support stop part 2022, thus completing the support action of the sealing ring 000. Then, it proceeds to the next assembly process with the assembly station.

[0044] Additionally, the travel distance of the feeding pin 202 as it descends along the Z-axis linear moving module can be set to control the sealing ring 000 to repeatedly support the material to the support stop portion 2022. Furthermore, the present invention includes a photoelectric sensor switch on the running track of the Z-axis linear moving module to quantitatively control its travel distance.

[0045] Preferably, the floating base 301 is also provided with an optical fiber sensor 800. The sensing end of the optical fiber sensor 800 is located corresponding to the material support stop part 2022, and is used to detect whether the sealing ring 000 on the material picking needle 202 is in place or whether the material is falling off.

[0046] Preferably, the floating base 301 is placed on the horizontal adjustment component 700, which is used to fine-tune the position of the floating base 301 to adjust the corresponding position of the support gap 3021 and the picking needle 202.

[0047] The horizontal adjustment assembly 700 includes two base guide rails 701, two support plates 702, a floating spring 703, and a push rod 704.

[0048] Two base guide rails 701 are fixed to the worktable (not shown) parallel to the linear slide rail 400. The two base guide rails 701 are spaced apart, and a support plate 702 is fixed to each end of the same side. A clearance space is provided between the two support plates 702. Each support plate 702 has a side guard and a bottom plate. Two floating springs 703 are connected in parallel at intervals on the inner wall of the side guard of one support plate 702. The working end of the push rod 704 passes through the side guard of the other support plate 702. The bottom surface of the floating base 301 is placed on the bottom plate of the two support plates 702 respectively, and one side of the base 301 abuts against each floating spring 703, while the opposite side of the base 301 abuts against the working end of the push rod 704. The discharge through hole 304 is located in the clearance space between the two support plates 702.

[0049] When the picking needle 202 moves linearly along the X-axis to above the support gap 3021, if it is found that the position of the picking needle 202 and the support gap 3021 are not completely aligned, the push rod 704 can be rotated or pushed to lengthen or shorten the end of the rod that passes through the side stop of the support plate 702. The floating base 301 will then move along the base guide rail 701, thereby finely adjusting the corresponding position of the support gap 3021 and the picking needle 202.

[0050] The push rod 704 of this invention is a micrometer to precisely control the movement dimension of the floating base 301.

[0051] Furthermore, a pulley 3022 is connected to the lower end of one of the adjacent sides of the two supporting connecting plates 3023 at each supporting station. This facilitates connection to the lifting mechanism 500 that drives the two supporting connecting plates 3023 to move closer or further apart.

[0052] Each lifting mechanism 500 includes a lifting cylinder 501 and a triangular lifting angle plate 502. The fixed end of each lifting cylinder 501 is connected to the base guide rail 701 between the two support plates 702, and its driving end is connected to the lifting angle plate 502. The pulleys 3022 on the two support connecting plates 3023 respectively abut against the two inclined sides of the lifting angle plate 502.

[0053] When the fiber optic sensor 800 detects that the sealing ring 000 on any of the picking pins 202 is not properly supported or that material is falling off any of the picking pins 202, in order to prevent the assembly of defective workpieces, the lifting cylinder 501 drives the lifting plate 502 to rise, and the two supporting plates 302 move away from each other along the linear slide rail 400. At the same time, the supporting gap 3021 at each supporting station increases, the two elastic elements 303 are also compressed, and the two picking pins 202 descend synchronously. The material is fed into the discharge through-hole 304; the lifting cylinder 501 drives the lifting angle plate 502 to descend, and the two support plates 302 move closer to each other along the linear slide rail 400. At the same time, the support gap 3021 resets, and the two elastic elements 303 also spring back to their original positions. At this time, the picking needle 202 rises with the Z-axis linear movement module. During the rising process of the picking needle 202, the sealing ring 000 on the picking needle 202 is blocked at the support gap 3021 and falls into the discharge through-hole 304. The setting of the elastic element 303 makes the above-mentioned lifting or lowering reset process more stable.

[0054] Preferably, a suction mechanism 600 is also provided below the material throwing through hole 304 to suck away and collect the sealing ring 000 inside the material throwing through hole 304, thus avoiding material waste. The suction mechanism 600 includes a collection bucket connected to the bottom surface of the material throwing through hole 304, and the collection bucket is equipped with a suction device.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
