Description

Technical Field

[0001] This invention belongs to the field of module shell polishing technology, specifically, it relates to a polishing device for the shell of a module after injection molding. Background Technology

[0002] After the module shell is injection molded, its outer wall needs to be polished to achieve an aesthetic appearance. However, when polishing the outer wall of the module shell, the traditional method of fixing the module shell relies on clamping. As a result, the clamping position may be blocked and polishing may not be possible. When the clamping position is changed for polishing in the future, uneven polishing may occur.

[0003] Chinese patent application CN206662990U discloses a positioning fixture for facilitating the polishing of mobile phone casings. By configuring the limiting side plates around the fixture's carrier plate to be movable vertically, when the mobile phone casing is placed in the cavity formed by the four limiting side plates, as the polishing head passes one of the limiting side plates, that side plate is pressed downwards to facilitate polishing the side of the mobile phone casing; while the other three sides maintain their original height, limiting the mobile phone casing. Because the four limiting side plates can move vertically, the polishing head can complete the polishing of the entire surface of the mobile phone casing in one go with a single positioning clamping, eliminating the need for secondary positioning clamping; effectively improving polishing efficiency and preventing scratches.

[0004] However, this technical solution still has at least the following drawbacks: although it can polish the various surfaces of the phone casing by sequentially lowering the limiting side plates, the sequential lowering of the limiting side plates reduces the efficiency of the entire process. Therefore, this invention is proposed. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a polishing device for the outer shell of a molded module. A support plate supports the inner wall of the outer shell, ensuring the outer wall is fully exposed while the outer shell is fixed, thus avoiding the inability to polish the clamped areas caused by traditional clamping methods and improving the polishing effect. A rotating bracket drives the support mechanism to rotate, enabling the removal, polishing, and unloading of the outer shell during a single rotation. This operation is simple, convenient, and quick. A placement slot allows for the placement of multiple outer shells at once, reducing the frequency of manual operation. Furthermore, the inclined end of the placement slot facilitates the individual removal of the outer shells.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0041] Example 1

[0042] like Figures 1 to 10 As shown, a polishing device for the outer shell of a molded module includes:

[0043] The transfer unit includes a power module 100. A rotating bracket 101 is installed at the output end of the power module 100. A support mechanism is provided on the rotating bracket 101. The support mechanism includes a support plate 113, an elastic release component, and a winding component. The support mechanism controls the opening and closing of the support plate 113 through the elastic release component and the winding component.

[0044] The polishing unit includes a polishing module 300, which is fixedly installed on the top of the power module 100. The polishing unit polishes the module shell through the polishing module 300.

[0045] The power module 100 is driven by a servo motor to provide the power to drive the rotating bracket 101 to rotate. The polishing module 300 consists of a polishing brush and a drive motor, and is equipped with detergent and water nozzles. The drive motor controls the polishing brush to rotate at high speed, and sprays detergent and water each time the module shell moves to the polishing module 300, so that the dirt on the outer wall of the module shell is removed in a short time.

[0046] like Figure 2 , Figure 3 , Figure 4As shown in the specific embodiment, a connecting mechanism is provided on one side of the supporting mechanism. The connecting mechanism includes a sliding component and a limiting component. The sliding component includes a first slider 102, which is movably sleeved on the rotating bracket 101. The limiting component includes a limiting block 103, one end of which is rotatably connected to the first slider 102. Rollers 104 are installed on both the upper and lower sides of the limiting block 103. In this configuration, the sliding friction of the limiting block 103 is changed to rolling friction by setting the rollers 104, which greatly reduces the frictional resistance. A magnet is provided between the first slider 102 and the rotating bracket 101 to increase the frictional force between the first slider 102 and the rotating bracket 101, preventing the first slider 102 from easily sliding when the rotating bracket 101 rotates.

[0047] like Figure 2 , Figure 3 , Figure 4 As shown, the limiting component further includes an upper guide rail 302 and a lower guide rail 303. A top plate 301 is mounted on the top of the upper guide rail 302, and one end of the top plate 301 is fixedly mounted on the top of the polishing module 300. The bottom of the lower guide rail 303 is fixedly mounted on the top of the power module 100 via a connecting bracket. The limiting block 103 is adapted to the upper guide rail 302 and the lower guide rail 303. The limiting component realizes the horizontal movement of the limiting block 103 through the upper guide rail 302 and the lower guide rail 303. In this configuration, when the limiting block 103 is in contact with the upper guide rail 302, it rolls using the roller 104 above the limiting block 103. When the limiting block 103 is in contact with the lower guide rail 303, it rolls using the roller 104 below the limiting block 103, thereby achieving horizontal movement of the limiting block 103 during its movement.

[0048] Example 2

[0049] like Figure 4 , Figure 5 As shown, in a specific embodiment, the elastic release assembly includes a fixing block 107, a support plate 108 installed at the end of the fixing block 107, a third slider 112 movably sleeved on the support plate 108, a support plate 113 fixedly connected to the third slider 112, a second slider 111 fixedly installed on one side of the third slider 112, a slide rod 109 movably inserted into the second slider 111, and a first spring 110 movably sleeved on the slide rod 109. In this configuration, the elastic force of the first spring 110 pushes the second slider 111 to move, and the second slider 111 drives the support plate 113 to move through the third slider 112, thereby causing the support plate 113 to support the four corners of the module shell.

[0050] like Figure 2 , Figure 4 , Figure 5As shown, the winding assembly further includes a connector 106, which is fixedly connected to the fixing block 107. A winding wheel 115 is rotatably connected inside the connector 106. A gear 116 is fixedly installed at the end of the winding wheel 115. A pull rope 114 is wound around the winding wheel 115, and one end of the pull rope 114 is fixedly installed on the second slider 111. In this configuration, when the winding wheel 115 rotates, it winds up the pull rope 114. One end of the pull rope 114 pulls the second slider 111, which in turn drives the third slider 112 to move. The third slider 112 overcomes the elastic force of the first spring 110 and drives the support plate 113 to retract, thereby causing the module housing to detach.

[0051] like Figure 2 , Figure 4 As shown, the supporting mechanism further includes a pulling assembly, which includes a first pull rod 200 and a second pull rod 201. The first pull rod 200 and the second pull rod 201 are rotatably connected. One end of the first pull rod 200 is fixedly connected to one end of the winding wheel 115. A connecting post 105 is fixedly installed on one end of the connecting piece 106. An inner ring 204 is movably sleeved on the connecting post 105. One end of the second pull rod 201 is rotatably connected to one side of the inner ring 204. An outer wheel 202 is rotatably sleeved on the outside of the inner ring 204. The pulling assembly also includes a guide ring 203, which is adapted to the outer wheel 202. In this setup, the polished module housing moves to the end of the lower guide rail 303 along with the support mechanism. At this time, the outer wheel 202 abuts against the guide ring 203, causing the inner ring 204 to move to one side. The first pull rod 200 and the second pull rod 201 pull the winding wheel 115 to rotate. At the same time, since the inner ring 204 and the outer wheel 202 are rotatably connected, the support mechanism moves when the outer wheel 202 abuts against the guide ring 203. The outer wheel 202 rolls along the guide ring 203 without causing the inner ring 204 to rotate, thus keeping the inner ring 204 in a stable direction.

[0052] like Figure 4 , Figure 5 As shown, a limiting component is further provided at the bottom of the supporting mechanism. The limiting component includes a counterweight 118, and a pull plate 117 is fixedly installed on the top of the counterweight 118. The top of the pull plate 117 is rotatably connected to the bottom of the connector 106. When the supporting mechanism rotates, the counterweight 118 in the limiting component reduces the degree of rotation of the supporting mechanism. In this configuration, by setting the counterweight 118, the supporting mechanism can maintain its direction unchanged while rotating with the rotating bracket 101. At the same time, the rotatable connection between the pull plate 117 and the connector 106 can effectively reduce the disturbance caused by the swing of the counterweight 118.

[0053] Example 3

[0054] like Figure 6 , Figure 7 , Figure 8As shown, in a specific embodiment, a feeding unit is provided at the bottom of the transfer unit. The feeding unit includes a placement groove 401. One end of the placement groove 401 is inclined relative to the rotation plane of the rotating bracket 101, and the vertical distance between the two inclined sides is adapted to the thickness of the module shell. A mounting bracket 400 is fixedly installed at the bottom of the placement groove 401, and the top of the mounting bracket 400 is fixedly connected to the power module 100. An elastic pushing mechanism is provided on the placement groove 401. In this configuration, when the support plate 113 at one end abuts against the inner wall of one end of the module shell, the support plate 113 at the other end remains detached from the module shell. As the support plate 113 drives the module shell to move, the other end of the module shell gradually moves towards the support plate 113 until the inner wall is completely in contact with the support plate 113. At this time, the support plate 113 completely removes the module shell from the placement groove 401, so that the module shell can be suspended on the support plate 113.

[0055] like Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the elastic pushing mechanism further includes a telescopic rod 402, on which a second spring 403 is movably sleeved. The elastic pushing mechanism pushes the module housing to move via the second spring 403. A baffle 404 is fixedly installed on two adjacent sides of the placement slot 401, forming a right-angled triangle with itself as a right-angled side. The straight line of the output direction of the elastic pushing mechanism passes through the interior of the right-angled triangle. In this configuration, the elastic force of the second spring 403 acts on the module housing to ensure that the module housing is continuously pushed. By passing the straight line of the output direction of the elastic pushing mechanism through the interior of the right-angled triangle, the force point of the elastic pushing mechanism is located between the triangle formed by the two baffles 404, preventing the module housing from falling off due to unbalanced force.

[0056] like Figure 1 , Figure 10 As shown, a feeding unit is further provided on one side of the transfer unit. The feeding unit includes a support rod 500, a guide rod 501 is fixedly installed on the top of the support rod 500, and guide blocks 502 are fixedly installed on both sides of the guide rod 501. A housing 600 is installed on the outside of the transfer unit. In this configuration, when the module housing moves to the guide rod 501, the top of the guide rod 501 inserts into the gap between the support plates 113. At this time, the module housing continues to descend and disengages from the support plates 113 under the action of the guide rod 501. Simultaneously, the module housing falls into the guide block 502. Under the action of the guide block 502, the trajectory of the falling device is prevented from overlapping with the movement trajectory of the supporting mechanism.

[0057] The implementation principle of a polishing device for a module shell after injection molding in this embodiment is as follows: When polishing the module shell, the module shells are first placed in batches in the placement groove 401. At this time, the elastic force of the second spring 403 drives the module shells to press against the baffle 404.

[0058] At this time, the power module 100 is activated, and the power module 100 drives the rotating bracket 101 to rotate, which in turn causes the supporting mechanism to rotate. When the supporting mechanism rotates to the bottom, the support plate 113 abuts against one side of the inner wall of the module housing and drives the module housing to move out. When the supporting mechanism rotates to the state of disengaging from the guide ring 203, the elastic force of the first spring 110 pushes the second slider 111 to move. The second slider 111 drives the support plate 113 to move through the third slider 112, thereby causing the support plate 113 to support the four corners of the module housing.

[0059] Since the counterweight 118 maintains the vertical position of the supporting mechanism by gravity, when the supporting mechanism rotates to the upper guide rail 302, the top of the limiting block 103 abuts against the upper guide rail 302 and moves horizontally under the action of the upper guide rail 302, while entering the lower guide rail 303. During this process, the supporting mechanism is limited by the upper guide rail 302 and the lower guide rail 303 and cannot rotate, so that the module shell can maintain a fixed direction.

[0060] During the movement of the module housing, the polishing brush on the polishing module 300 rotates at high speed and sprays detergent to efficiently clean the outer wall of the module housing. At the same time, the polishing brush on the polishing module 300 is set at multiple angles, so that the polishing module 300 can polish the module housing more comprehensively.

[0061] After polishing, the module shell moves to the end of the lower guide rail 303 along with the support mechanism. At this time, the outer wheel 202 pushes against the guide ring 203, causing the inner ring 204 to move to one side. The first pull rod 200 and the second pull rod 201 pull the take-up wheel 115 to rotate. The take-up wheel 115 pulls the second slider 111 to move through the take-up pull rope 114, thereby driving the support plate 113 to retract. At this time, the module shell is separated from the support mechanism under the action of the guide rod 501 and the guide block 502, so that the inner wall can be polished in the future.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
