Description

Technical Field

[0001] The utility model belongs to the technical field of mobile phone processing equipment, and in particular relates to a multi-angle rotation adjustment mechanism and a mobile phone middle frame burr removal device. Background Art

[0002] In mobile phone manufacturing, flash refers to burrs and irregular projections on the edges of metal or other material midframes after processing. Nylon sandblasting is a commonly used process for removing these irregularities, effectively improving the product's appearance and feel. According to the latest information, nylon sandblasting machines can be used to remove flash and burrs on precision plastic or metal parts such as mobile phone cases. Due to the toughness and non-cutting properties of nylon sand, it does not damage the product during use.

[0003] Traditional nylon sand blasting equipment includes a positioning and moving mechanism, a clamping jig and a sandblasting tube. The sandblasting tube is arranged at the output end of the positioning and moving mechanism. The clamping jig is used to limit the middle frame of the mobile phone. The positioning and moving mechanism drives the sandblasting tube to move to one side of the clamping jig so that the sandblasting tube is aligned with the burr generating position of the middle frame of the mobile phone.

[0004] In the prior art, in nylon sand blasting equipment, the bearing surface of the clamping fixture is mostly set in a horizontal direction, the sandblasting tube is set vertically, the positioning and moving mechanism can only drive the sandblasting tube to move along the three-axis direction, the sandblasting tube is always set in a vertical state, and the sandblasting direction is always downward on the middle frame of the mobile phone; in order to prevent the nylon sand from accidentally touching other areas of the middle frame of the mobile phone, the clamping fixture is designed as a covering structure. After covering the entire middle frame of the mobile phone, a light hole is drilled at the position of the burr of the middle frame of the mobile phone, so that the nylon sand can contact the burr through the light hole; however, the burr of the middle frame of the mobile phone is generally made of plastic, which is formed during the injection molding process. The direction of the burr is not the only setting. Sandblasting only from the vertical direction will result in the burr that is close to the moving direction of the nylon sand cannot be scraped off, and the burr removal effect is poor, which needs to be improved urgently. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-angle rotation adjustment mechanism and a burr removal device for the middle frame of a mobile phone, aiming to solve the technical problem that the sandblasting direction of the sandblasting tube is fixed in the existing technology, and sandblasting is only performed from a single direction, which will result in the burr in the direction close to the movement direction of the nylon sand being unable to be scraped off, resulting in a poor burr removal effect.

[0006] To achieve the above object, an embodiment of the present utility model provides a multi-angle rotation adjustment mechanism, including a mounting base and a rotation assembly. The mounting base is arranged in a U-shaped structure, and a rotation groove is formed at the middle position of the mounting base; the rotation assembly is arranged on the mounting base, and the output end of the rotation assembly is located in the rotation groove; wherein, the rotation assembly includes a driving component and a carrier plate. The driving component is arranged on the mounting base. One end of the carrier plate is rotatably connected to the rotation groove, and the other end of the carrier plate is connected to the output end of the driving component. A jig for limiting the middle frame of the mobile phone is arranged on the carrier plate.

[0007] Optionally, the mounting base includes a bottom plate and a vertical plate. The vertical plate is vertically arranged at one end of the bottom plate. The bottom plate and the vertical plate are arranged in an L-shaped structure. The driving component is arranged at the end of the bottom plate away from the vertical plate. One end of the carrier plate is rotatably connected to the vertical plate, and the other end of the carrier plate is connected to the output end of the driving component. The rotation groove is formed among the driving component, the bottom plate and the vertical plate.

[0008] Optionally, the mounting base further includes a dust collection unit. The dust collection unit is arranged on the bottom plate and below the carrier plate.

[0009] Optionally, the dust collection unit includes a vacuum suction plate and a baffle. The baffle is arranged at the edge of the bottom plate and is in an inclined state. The vacuum suction plate is arranged on the bottom plate and on one side of the baffle. The vacuum suction plate is used for adsorbing the mixture of nylon sand and burrs falling from the jig on the carrier plate.

[0010] Optionally, adsorption holes are formed in the end face of the vacuum suction plate facing the carrier plate, and an output hole is formed in the side wall of the vacuum suction plate. The output hole is connected to an output pipe through a pipeline, and the output end of the output pipe is bent downward.

[0011] Optionally, the driving component includes a driving motor and a transmission box. The driving motor is arranged on the bottom plate, the transmission box is arranged on the mounting base, the output end of the driving motor is drivingly connected to the transmission box, and the end of the carrier plate is connected to the output end of the transmission box.

[0014] The above one or more technical solutions in the multi-angle rotation adjustment mechanism and the mobile phone middle frame burr removal device provided by the embodiment of the utility model have at least one of the following technical effects: the operator mounts the mold holding the mobile phone middle frame on the supporting plate, and the sandblasting equipment starts the sandblasting operation. During the sandblasting operation, the driving component drives the supporting plate to rotate, and the supporting plate and the nylon sand output path of the sandblasting equipment form an inclined angle deviation. The light hole on the mold for the nylon sand to pass through is adjusted as the supporting plate rotates; compared with the fixed sandblasting direction design of the sandblasting tube in the prior art, sandblasting is only performed from a single direction, which will result in the burr facing the direction close to the movement direction of the nylon sand cannot be scraped off, resulting in a poor burr removal effect. The multi-angle rotation adjustment mechanism and the mobile phone middle frame burr removal device provided by the embodiment of the utility model adopt a rotating structure to adjust the angle of the mold at the sandblasting output end, so that the burr located in the light hole of the mold can be impacted by the nylon sand at different angles, effectively improving the burr removal efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0030] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0031] In one embodiment of the present invention, Figures 1 to 4As shown in the figure, a multi-angle rotation adjustment mechanism is provided, including a mounting base 100 and a rotation component 200. The mounting base 100 is arranged in a U-shaped structure, and a rotation groove 300 is formed in the middle position of the mounting base 100; the rotation component 200 is arranged on the mounting base 100, and the output end of the rotation component 200 is located in the rotation groove 300; wherein, the rotation component 200 includes a driving component 210 and a carrier plate 220. The driving component 210 is arranged on the mounting base 100. One end of the carrier plate 220 is rotatably connected to the rotation groove 300, and the other end of the carrier plate 220 is connected to the output end of the driving component 210. A jig for limiting the middle frame of the mobile phone is arranged on the carrier plate 220.

[0032] Another embodiment of the present invention further provides a burr removal device for the middle frame of a mobile phone, including the above multi-angle rotation adjustment mechanism.

[0033] Specifically, an operator installs a mold clamping the middle frame of the mobile phone on the carrier plate 220, and the sandblasting equipment starts sandblasting operations. During the sandblasting operations, the driving component 210 drives the carrier plate 220 to rotate, and the carrier plate 220 forms an angular deviation with the nylon sand output path of the sandblasting equipment. The light holes on the mold for nylon sand to pass through are angle-adjusted as the carrier plate 220 rotates; compared with the prior art in which the sandblasting direction of the sandblasting pipe is fixed and sandblasting is only carried out from a single direction, which will cause burrs close to the moving direction of the nylon sand not to be scraped off and the burr removal effect is lacking. The multi-angle rotation adjustment mechanism and the burr removal device for the middle frame of the mobile phone provided by the embodiment of the present invention adopt a rotating structure to adjust the angle of the mold at the sandblasting output end, so that the burrs in the light holes of the mold can be impacted by nylon sand at different angles, effectively improving the burr removal efficiency.

[0034] As Figures 1 to 4 As shown in the figure, in another embodiment of the present invention, the mounting base 100 includes a bottom plate 110 and a vertical plate 120. The vertical plate 120 is vertically arranged at one end of the bottom plate 110. The bottom plate 110 and the vertical plate 120 are arranged in an L-shaped structure. The driving component 210 is arranged at the end of the bottom plate 110 away from the vertical plate 120. One end of the carrier plate 220 is rotatably connected to the vertical plate 120, and the other end of the carrier plate 220 is connected to the output end of the driving component 210. The rotation groove 300 is formed among the driving component 210, the bottom plate 110 and the vertical plate 120.

[0035] In this embodiment, the supporting plate 220 includes a plate body 221 and a connecting shaft 222. The mold is arranged on the plate body 221. The top of the vertical plate 120 is provided with a mounting groove 121. The connecting shaft 222 is arranged at the end of the plate body 221 facing away from the mold. The end of the connecting shaft 222 is rotatably connected in the mounting groove 121. The mounting groove 121 passes through the top of the vertical plate 120. The bottom of the mounting groove 121 is provided with a semi-circular bushing 122. The connecting shaft 222 is installed downward from the top of the vertical plate 120 into the mounting groove 121 until it is slidably connected with the semi-circular bushing 122, thereby completing the installation.

[0036] like Figures 1 to 4 As shown, in another embodiment of the present invention, the mounting base 100 further includes a dust collecting unit 130 , which is disposed on the bottom plate 110 and below the supporting plate 220 .

[0037] Specifically, after sandblasting is completed, some nylon sand remains in the light hole of the mold. At this time, the driving component 210 drives the carrier plate 220 to rotate 180°, so that the light hole of the mold is set downward, and the nylon sand in the light hole falls into the dust collecting unit 130 under the influence of gravity, so that the nylon sand is easily collected. Compared with the traditional mold residual nylon sand, which needs to be cleaned manually and affects efficiency, the utility model adopts a rotating structure to achieve angle adjustment while also being able to perform a flipping action, so that all the nylon sand in the light hole can automatically detach from the light hole, effectively improving the efficiency of burr removal.

[0038] like Figures 1 to 4 As shown, in another embodiment of the present utility model, the dust collection unit 130 includes a vacuum suction plate 131 and a baffle 132, the baffle 132 is arranged at the edge of the base plate 110, and the baffle 132 is arranged in an inclined state, the vacuum suction plate 131 is arranged on the base plate 110 and is located on one side of the baffle 132, the vacuum suction plate 131 is used to absorb the nylon sand and burr mixture dropped from the jig on the supporting plate 220. In this embodiment, the adsorption hole 133 of the vacuum suction plate 131 is set upward, and the aperture of the adsorption hole 133 is much larger than the nylon sand. The nylon sand adsorbed by the vacuum suction plate 131 moves along the preset pipeline path to achieve convenient collection.

[0039] Specifically, the end surface of the vacuum suction plate 131 facing the supporting plate 220 is penetrated with an adsorption hole 133, and the side wall of the vacuum suction plate 131 is penetrated with an output hole, which is connected to the output pipe, and the output end of the output pipe is bent downward.

[0040] like Figures 1 to 4As shown, in another embodiment of the present invention, the driving component 210 includes a driving motor 211 and a transmission box 212, the driving motor 211 is arranged on the base plate 110, the transmission box 212 is arranged on the mounting seat 100, the output end of the driving motor 211 is drive-connected to the transmission box 212, and the end of the supporting plate 220 is connected to the output end of the transmission box 212. In this embodiment, the driving motor 211 is a servo motor, the transmission box 212 is a speed-changing gear box, and the output end of the transmission box 212 is provided with a clamping claw, which is fixedly connected to the connecting shaft 222. The use of a servo motor structure as a driving source is conducive to improving the rotation adjustment accuracy of the driving component 210, so as to adapt to the sandblasting angle requirements of the middle frame of different models of mobile phones. The rotation angle range of the output end of the transmission box 212 is 0~360°

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
