Description

Technical Field

[0001] This utility model belongs to the field of mobile phone case and equipment technology, specifically a mobile phone case plug installation module. Background Technology

[0002] There are many styles of mobile phone cases, and their manufacturing processes range from simple injection molding to complex welding and painting. In existing technologies, customers sometimes have special requirements, necessitating the separate production of the buttons and the phone case, followed by assembly. The specific method is illustrated in the publicly available technical document "CN118560043B, A Method for Installing Buttons on a Mobile Phone Case." The phone case and buttons fit tightly together, and there are no gaps between them after assembly.

[0003] According to the requirements, the phone case needs to be painted before assembly. However, painting the phone case is done all over, which will cause the inner diameter of the button holes to shrink due to the thickness of the paint. This will prevent the buttons from being placed in the holes during the later assembly process. The current method is to install plugs at the holes before painting to cover the inner diameter and surrounding areas of the holes, so that the paint cannot adhere to these areas and maintain the original size of the holes. Since the plugs need to be removed later, they are assembled. However, the plugs are relatively small, and it is not practical to assemble them manually, which is very inefficient.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] Please refer to Figure 1-11 ;

[0040] The installation mold base described in this utility model aims to automatically install plugs on mobile phone cases without manual operation, thereby improving work efficiency. It should be noted that since there are multiple button holes in the mobile phone case, multiple installation mold bases are used in the whole machine to form an assembly line operation. In addition, in order to enable the plug to be disassembled and to cover the outer and inner circumferential surfaces of the holes, an upper and lower interlocking design is adopted for the outer plug body 62 and the inner plug body 61. Specifically, it includes a transfer device 1, an inner plug feeding device 2, an outer plug feeding device 3, a jig 4, and a pressing device 5.

[0041] Because the assembly position and the feeding position are different, the transfer device 1 is needed to switch the position of the plug. More specifically, the phone case is first fixed on the fixture 4 by the feeding device, so that the phone case is in a side position. In this embodiment, the fixture 4 includes a fixture body 4141. A cavity 42 for the phone case to be placed is provided on one side of the fixture body 4141. A pressure plate 43 is provided on the upper and side of the cavity 42. A spring pressure member 44 is provided between the pressure plate 43 and the inner wall of the cavity 42. When feeding, the pressure plate 43 on the side is squeezed by the external device to make room for the phone case to enter. Then the pressure plate 43 is released and the phone case is squeezed by the spring pressure member 44 to move closer to the cavity 42 and fix it. In addition, a clearance position 45 is provided on the lower side of the fixture 4, corresponding to the button hole position.

[0042] At the same time, the inner plug feeding device 2 and the outer plug feeding device 3 operate simultaneously. Initially, the plug body fixing component 11 is in the open state. Then, the inner plug body 61 and the outer plug body 62 are respectively placed into the inner plug fixing position 1124 and the outer plug fixing position 1133 of the plug body fixing component 11. Then, the position of the plug body fixing component 11 is switched by the transfer device 1 so that it corresponds with the fixture 4. After that, the plug body fixing component 11 can extend into the fixture 4. It should be noted that, since the space in the fixture 4 is relatively narrow, only the inner plug fixing position 1124 of the plug body fixing component 11 extends into it, while the outer plug fixing position 1133 is located on the outside. In addition, regarding the movement process, it can be that the external equipment drives the fixture 4 to move closer to the plug body fixing component 11, or the plug body fixing component 11 moves closer to the fixture 4 as a whole. No matter which method is used, the same technical effect can be achieved.

[0043] After the rising process, the inner plug body 61 and the outer plug body 62 are located on the inner and outer sides of the phone case, respectively, and correspond to the button holes. Finally, the plug fixing component 11 is closed by the pressing device 5, that is, the inner plug body 61 and the outer plug body 62 approach each other and partially pass through the button holes and fasten together. The inner plug body 61 and the outer plug body 62 fasten together to shield the inner diameter and outer circumference of the hole, so as to prevent paint from adhering to it and affecting the process flow. In addition, through the cooperation of the above components, the plug body is automatically assembled without manual intervention, which improves work efficiency.

[0044] One embodiment of the plug fixing assembly 11 of this utility model is described below. Figure 4 and Figure 5Specifically, it includes a fixed base 111, on which a first movable base 1121 and a second movable base 1131 are slidably connected. A spring-loaded assembly 114 is provided between the two. Preferably, an abutment block 115 is provided between the first movable base and the second movable base 1131. The spring-loaded assembly 114 is installed on the abutment block 115 and applies external force to the first movable base 1121 and the second movable base 1131 respectively, so that they move away from each other. In addition, in order to prevent the first movable block 1121 and the second movable block from sliding out of the fixed base 111, a limiting plate 116 is provided at the upper and lower ends of the fixed base 111 respectively to limit the range of motion of the first movable base 1121 and the second movable base 1131.

[0045] A first fixed block 1122 is installed in the first movable seat 1121, and a first movable block 1123 is embedded in the first fixed block 1122. The first movable block 1123 can move relative to the first fixed block 1122, and a first return spring (not shown) is located between the two and abuts against them. More specifically, there is a gap in the first fixed block 1122, and the first movable block 1123 is placed in the gap and partially inserted into the first fixed block 1122. The first return spring pushes the first movable block 1123 to move laterally, so that the bottom surfaces of the two together form an inner plug fixing position 1124; when the inner plug... When the body 61 is being fed, the first movable block 1123 is slightly pushed laterally to compress the first return spring by squeezing, and the first return spring applies a reverse force to push the first movable block 1123, thereby clamping and fixing the inner plug body 61. Preferably, the outer periphery of the upper surface of the inner plug body 61 has a chamfer, so it can easily enter the inner plug fixing position 1124 when being fed. Of course, in the initial state, the length of the inner plug fixing position 1124 formed by the first fixing block 1122 and the first movable block 1123 is only slightly smaller than the length of the inner plug body 61, so it will not hinder the feeding.

[0046] A second fixing block 1132 is installed on the second movable seat 1131. The second fixing block 1132 is provided with an outer plug fixing position 1133. A second insert plate 1134 is embedded in the second fixing block 1132. The second insert plate 1134 can extend out from the outer plug fixing position 1133. A second return spring (not shown) is provided between the second insert plate and the second fixing block 1132. Of course, the second insert plate is inserted from bottom to top and extends out of the outer plug fixing position 1133 under the action of the second return spring. Based on the structural characteristics of the outer plug body 62, a slot 63 is provided in the middle position for the inner plug body 61 to be fastened. Therefore, when feeding, the second insert plate passes through the slot 63 to fix the outer plug body 62.

[0047] When the inner plug body 61 and the outer plug body 62 are combined, the inner plug body 61 partially passes through the slot 63 of the outer plug assembly and is fixed together by an interference fit. At the same time, it presses down on the second insert plate that passes through the slot 63, causing it to move downward and exit the slot 63.

[0048] Preferably, a first insert plate 1125 is inserted into the first fixing block 1122, and the first insert plate 1125 can extend from the inner plug fixing position 1124. A third return spring (not shown) is provided between the first fixing block 1122 and the first insert plate 1125. Under the action of the third return spring, the first insert plate 1125 does not initially extend from the inner plug fixing position 1124. During operation, the pressing device 5 abuts against the end of the first insert plate 1125. Since the spring force of the third return spring is greater than the spring force of the spring pressing component 114, the spring is pressed first. The pressing component 114 compresses the first movable seat 1121, which moves it downward. The second movable seat 1131 moves upward simultaneously. When the first movable seat 1121 and the second movable seat 1131 come into contact with the abutment block 115, they stop moving. At the same time, the inner plug body 61 and the outer plug body 62 are very close. Then the pressing device 5 continues to apply pressure downward, pushing the first insertion plate 1125 to continue moving downward and extending the inner plug fixing position 1124 to push out the inner plug body 61. At the same time, pressure is applied to combine it with the outer plug body 62.

[0049] One embodiment of the present invention relates to the transfer device 1, see reference to Figure 3 and Figure 6 Specifically, it includes a turntable assembly 12, which can be a combination of a base, a turntable and a motor. The turntable is driven to rotate by the motor, etc. This is a common technical means and will not be described in detail here. Moreover, since the inner plug feeding device 2 and the outer plug feeding device 3 are relatively large, they cannot feed materials at the same station at the same time. Therefore, several plug fixing components 11 are set in the turntable to achieve staggered feeding.

[0050] In addition, regarding the above-mentioned method of entering the phone case, the fixture 4 is usually fixed in the conveying device and cannot move. Therefore, in this embodiment, the turntable assembly 12 is moved forward as a whole. That is, the bottom of the turntable assembly 12 is equipped with a translation component 13, which is used to push the turntable assembly 12 towards the fixture 4 so that the plug fixing component 11 can be placed in the corresponding position of the phone case.

[0051] It should be noted that when the translation component 13 drives the turntable component 12 to move forward as a whole, it is impossible to feed materials.

[0052] One embodiment of the pressing device 5 of this utility model is described below. Figure 6Specifically, it includes a first fixed bracket 51, on which a first cylinder 52 and a second cylinder 53 are mounted vertically. The output ends of the first cylinder 52 and the second cylinder 53 are respectively equipped with a first pressing member 54 and a second pressing member 55. The first pressing member 54 is used to push the first movable seat 1121, and the second pressing member 55 is used to push the second movable seat 1131. Since the cylinder is used as the power source, a fixed method is adopted to avoid the air pipe from getting tangled. The first cylinder 52 and the second cylinder 53 drive the first pressing member 54 and the second pressing member 55 to move respectively. The first pressing member 54 pushes out of the first movable seat 1121, and the second pressing member 55 abuts against the end of the second movable seat 1131 or the first insert plate 1125, thereby pushing the two closer to each other.

[0053] One embodiment of the present invention relates to the inner plug feeding device 2, see below. Figures 7-9 The first multi-axis moving assembly 21 is provided with a second fixed bracket 22 and a third cylinder 23 installed at the terminal moving part of the first multi-axis moving assembly 21. A third fixed block 24 is installed on the second fixed bracket 22. The third fixed block 24 is provided with an inner plug feeding position 25. A third pressing member 26 is installed at the output end of the third cylinder 23. Preferably, the second fixed bracket 22 is "L" shaped to reduce its volume and allow it to extend between the first movable seat 1121 and the second movable seat 1131.

[0054] Furthermore, it also includes an inner plug conveying assembly, which includes a first vibratory plate component 271. The output end of the first vibratory plate component is connected to a first conveying channel 272. A fourth cylinder 273 is installed at the output end of the first conveying channel 272. A fourth fixing block 274 is installed at the moving end of the fourth cylinder 273. A first transition placement position 275 that can communicate with the first conveying channel 272 is provided on the fourth fixing block 274. A fifth cylinder 276 is installed on one side of the first conveying channel 272. A push rod assembly 277 is installed at the output end of the fifth cylinder 276. The push rod assembly 277 can be inserted into the transition placement position to push out the inner plug body 61.

[0055] First, the inner plug body 61 is sequentially output to the first conveying channel 272 through the first vibrating plate component 271. In the initial state, the first transition placement position 275 is aligned with the end of the first conveying channel 272, so that the inner plug body 61 can enter the first transition placement position 275. Then, the fourth cylinder 273 pushes the fourth fixing block 274 to move laterally, so that the first transition placement position 275 is misaligned with the first conveying channel 272. Both ends of the first transition placement position 275 are open. One end is aligned with the end of the push rod assembly 277. At the same time, the inner plug loading position 25 is aligned with the other end opening. Then, the fifth cylinder 276 pushes the push rod assembly 277 into the first transition placement position 275, and at the same time pushes the inner plug body 61 into the inner plug loading position 25.

[0056] Since the space of the inner plug loading position 25 is slightly larger than the outer diameter of the inner plug body 61, the inner plug body 61 may loosen and fall off. Therefore, it is necessary to extend the third cylinder 23 to push the third pressing member 26, so that the third pressing member 26 extends from the inner plug loading position 25 to the side, and cooperates with the third fixing block 24 to clamp and fix the inner plug body 61.

[0057] Driven by the first multi-axis moving assembly 21, it moves from bottom to top toward the inner plug fixing position 1124. Before being placed in the inner plug fixing position 1124, the third cylinder 23 drives the third pressing member 26 to retract and release the clamping state.

[0058] One embodiment of the present invention relates to the external plug feeding device 3, see reference to Figure 10 and Figure 11 Specifically, it includes a second multi-axis moving assembly 31, a third fixed bracket 32 ​​is installed at the terminal moving part of the second multi-axis moving assembly 31, a sixth cylinder 33 is installed on the third fixed bracket 32; a connecting part 34 is installed at the output end of the sixth cylinder 33, preferably, the connecting part 34 is slidably connected to the third fixed bracket 32, an "L"-shaped connecting block 35 is installed on the outside of the connecting block 35, and a fixing part 36 for obtaining the outer plug body 62 is provided at the lower end of the connecting block 35. In this embodiment, the fixing part 36 can be fixed by adsorption.

[0059] In another embodiment, taking advantage of the characteristic of the outer plug body 62 having a slot 63, the fixing part 36 is a pin. When acquiring, the sixth cylinder 33 pushes the pin downward and inserts it into the slot 63 to acquire the outer plug body 62. Demolding is also required during material loading. For this purpose, a seventh cylinder 37 is also installed on the third fixing bracket 32. The output end of the seventh cylinder 37 is connected to an "L"-shaped linkage part 38. The linkage part 38 extends to the pin, and a demolding hole for the pin to pass through is provided on the linkage part 38. The pin is kept in the state of passing through the demolding hole, and the linkage part 38 is located above the outer plug body 62. When it is necessary to push the outer plug body 62 out of the pin, the seventh cylinder 37 pushes the linkage part 38 downward, and at the same time, it pushes the outer plug body 62 downward to disengage it from the pin.

[0060] Furthermore, it also includes an external conveying assembly, which includes a second vibrating plate component 391. The output end of the second vibrating plate component is connected to a second conveying channel 392. A base 393 is installed near the end of the second conveying channel 392. A drive motor 394 is installed in the base 393 and a feeding plate 395 is rotatably connected thereto. The output end of the drive motor 394 is connected to the feeding plate 395. The feeding plate 395 is provided with a plurality of second transition placement positions 396. One end of each second transition placement position 396 is open and can correspond to the end of the second conveying channel 392.
