[0002] Currently, many consumer electronic product shells are made of metal. Since the front and sides of the consumer electronic product shells are appearance surfaces, they need to be further processed, such as sandblasting. However, the assembly holes such as screw holes and pin holes opened on the front and sides of the consumer electronic product shells do not need to be processed. Therefore, protective plugs need to be inserted into various assembly holes to avoid damage to the assembly holes during the processing of the metal shell.

[0003] There are currently two ways to assemble protective plugs. One is to manually install protective plugs in the corresponding assembly holes for protection. However, since the assembly holes of some shell products are small in size and the protective plugs are generally soft plug structures, such as rubber plugs, manual operation is difficult, which not only has low production efficiency, but also easily leads to low product yield. The other is to assemble on an automatic production line. First, the protective plug is assembled in the assembly hole on the front of the shell product on the first assembly equipment, and then the shell product is transported to the second assembly equipment through the assembly line. The protective plug is assembled in the assembly hole on the side of the shell product on the second assembly equipment.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Please refer to Figures 1 to 12 The protective plug assembly machine of the utility model embodiment is used to install the protective plug 1 in the assembly hole 202 of the side 201 of the product 2. The protective plug assembly machine includes a positioning mechanism 3 and an assembly mechanism 4. The positioning mechanism 3 includes a base 301, a flip positioning assembly 302, a clamping assembly 303 and a flip driving assembly 304. The flip positioning assembly 302 is mounted on the base 301, and the flip positioning assembly 302 can be flipped relative to the base 301, for example, from Fig.11 The horizontal position shown is flipped to Fig. 9 vertical position as shown, or from Fig. 9 The vertical position shown is flipped to Fig.11 The flip positioning assembly 302 is used to position the product 2. In the initial state, the flip positioning assembly 302 is in a horizontal position. When the flip positioning assembly 302 is in a horizontal position, the front side 203 of the product 2 faces upwards. Fig.11The front 203 of the product 2 is shown in the figure. The clamping assembly 303 is connected to the flip positioning assembly 302, and the clamping assembly 303 is used to fix the product 2 to the flip positioning assembly 302 to prevent the product 2 from moving on the flip positioning assembly 302. The flip driving assembly 304 is connected to the base 301 and the flip positioning assembly 302 respectively. When the product 2 is fixed to the flip positioning assembly 302, the flip driving assembly 304 is used to drive the flip positioning assembly 302 to flip from a horizontal position to a vertical position, so that the assembly hole 202 of the side 201 of the product 2 fixed on the flip positioning assembly 302 is set upward. The assembly mechanism 4 includes a needle assembly 401. The needle assembly 401 is used to install the protective plug 1 in the assembly hole 202. The needle assembly 401 is arranged above the positioning mechanism 3, and the needle assembly 401 can move along the Z direction to install the protective plug 1 in the assembly hole 202. When the protection plug 1 is installed in the assembly hole 202 of the side surface 201 of the product 2, the flip driving assembly 304 is also used to drive the flip positioning assembly 302 to flip from a vertical position to a horizontal position.

[0035] In some examples, the product 2 may be a housing of a consumer electronic product, and the product 2 may be made of metal. The protective plug 1 may be a rubber plug. In other embodiments, the product 2 may be other products or other materials, and the protective plug 1 may be other materials.

[0036] In the protective plug assembly machine of the utility model embodiment, the flip positioning component 302 can be flipped on the base 301. After the product 2 is positioned on the flip positioning component 302 and fixed on the flip positioning component 302 by the clamping component 303, the flip positioning component 302 is flipped to a vertical position by the flip driving component 304, so that the assembly hole 202 of the side 201 of the product 2 fixed to the flip positioning component 302 can be set upward, and then the protective plug 1 can be installed in the assembly hole 202 by the needle component 401 that can move along the Z direction. It is not only easy to use, but also can quickly and effectively install the protective plug 1 in the assembly hole 202 on the side 201 of the product 2, thereby improving production efficiency and product yield, and it is unnecessary to use a multi-joint robot with high flexibility, thereby reducing production costs.

[0037] In some preferred embodiments, please refer to Figures 2 to 7 The flipping and positioning assembly 302 includes a flipping seat 3021 and a positioning seat 3022. The flipping seat 3021 is flippably connected to the base 301. The positioning seat 3022 is fixed to the flipping seat 3021, and the positioning seat 3022 has a positioning surface 30221. The positioning surface 30221 is used to support the back side 204 of the product 2, so that the front side 203 of the product 2 is positioned upward on the positioning seat 3022 located in a horizontal position. Fig.11The orientation of the front side 203 of the product 2 shown. The positioning seat 3022 also has a positioning portion 30222. The positioning portion 30222 is convexly arranged on the positioning surface 30221, and the positioning portion 30222 is used to position the side 201 of the product 2. The clamping assembly 303 is connected to the flip seat 3021. In some embodiments, the clamping assembly 303 can be used to abut the side 201 of the product 2 to press the product 2 against the positioning portion 30222 of the positioning seat 3022, thereby cooperating with the positioning portion 30222 of the positioning seat 3022 to clamp the product 2. In other embodiments, the clamping assembly 303 can be used to abut the front side 203 of the product 2 to press the product 2 against the positioning surface 30221 of the positioning seat 3022, thereby cooperating with the positioning surface 30221 of the positioning seat 3022 to clamp the product 2. In some other embodiments, the clamping assembly 303 can not only be used to abut the side 201 of the product 2 to press the product 2 against the positioning portion 30222 of the positioning seat 3022, but the clamping assembly 303 can also be used to abut the front side 203 of the product 2 to press the product 2 against the positioning surface 30221 of the positioning seat 3022.

[0038] It is understandable that the shape of the positioning surface 30221 can be set as required, and can be set as a normal plane, or a grooved surface or an irregular surface that imitates the back 204 of the product 2, or other surface structures, which are not limited here, as long as the positioning surface 30221 can be supported on the back 204 of the product 2, so that the front 203 of the product 2 is positioned upward on the positioning seat 3022 located in a horizontal position. It is understandable that the shape of the positioning part 30222 can also be set as required, and the number of the positioning parts 30222 and the distribution of the positioning parts 30222 on the positioning seat 3022 can also be arranged as required, which are not limited here, as long as the positioning part 30222 can be positioned on the side 201 of the product 2 when the product 2 is positioned on the positioning surface 30221.

[0039] It is understandable that when the clamping assembly 303 abuts against the side 201 of the product 2, the clamping assembly 303 can abut against the side 201 of the product 2 having the assembly hole 202, and the clamping assembly 303 can also abut against the side 201 of the product 2 not having the assembly hole 202, as long as it is ensured that when the clamping assembly 303 abuts against the side 201 of the product 2, the clamping assembly 303 does not block the assembly hole 202 on the side 201 of the product 2.

[0040] Optionally, refer to Figures 2 to 7, the clamping assembly 303 may include a first clamping member 3031. The first clamping member 3031 includes a first driving cylinder 30311 and a first clamping portion 30312. The first driving cylinder 30311 has a cylinder body 303111 and a piston rod 303112. The cylinder body 303111 of the first driving cylinder 30311 is fixed to the flip seat 3021, and the piston rod 303112 of the first driving cylinder 30311 is used to push the first clamping portion 30312 to move. The first clamping portion 30312 is connected to the flip seat 3021 through the elastic portion 30313, and the first clamping portion 30312 can cooperate with the positioning portion 30222 to clamp the product 2. The elastic portion 30313 can be elastically deformed along the axial direction of the elastic portion 30313. When the piston rod 303112 of the first driving cylinder 30311 is extended, the piston rod 303112 of the first driving cylinder 30311 can push the first clamping part 30312 to move in the direction away from the positioning part 30222, thereby increasing the distance between the first clamping part 30312 and the positioning part 30222, so that the product 2 can be positioned on the positioning surface 30221 or the product 2 can be released. At this time, under the action of the extended piston rod 303112 of the first driving cylinder 30311, the first clamping part 30312 squeezes the elastic part 30313, so that the elastic part 30313 is compressed. When the piston rod 303112 of the first driving cylinder 30311 is retracted, the first clamping portion 30312 moves toward the positioning portion 30222 under the rebound effect of the elastic portion 30313 until the first clamping portion 30312 abuts against the side surface 201 of the product 2, thereby pressing the product 2 against the positioning portion 30222. The first clamping member 3031 can cooperate with the positioning portion 30222 of the positioning seat 3022 to clamp the product 2, so that the product 2 is fixed on the flip positioning assembly 302, thereby preventing the product 2 from moving during the subsequent assembly process.

[0041] In some examples, a connecting seat 3023 may be fixed on the flip seat 3021. One axial end of the elastic portion 30313 abuts against the connecting seat 3023, and the other axial end of the elastic portion 30313 abuts against the first clamping portion 30312. The elastic portion 30313 may include a guide body 303131 and a spring 303132. The guide body 303131 may be a guide structure such as a guide rod or a guide sleeve, and the spring 303132 is coaxially connected to the guide body 303131.

[0042] In one example, the first clamping member 3031 includes two first clamping parts 30312, namely, a first clamping part 30312a and a first clamping part 30312b. The first clamping part 30312a is connected to the elastic part 30313a, and the first clamping part 30312b is connected to the elastic part 30313b. The first clamping member 3031 also includes a connecting part 30314. A first guide groove 30223 penetrating the positioning seat 3022 is provided at the lower end of the positioning seat 3022. When the flip positioning assembly 302 is in a horizontal position, the first guide groove 30223 extends along the X direction. When the flip positioning assembly 302 is flipped to a vertical position, the first guide groove 30223 extends along the Z direction. The connecting part 30314 is confined in the first guide groove 30223, and the connecting part 30314 can move in the first guide groove 30223 along the length direction of the first guide groove 30223. One end of the connecting portion 30314 is exposed outside the first guide groove 30223 and can be abutted against the piston rod 303112 of the first driving cylinder 30311. The other end of the connecting portion 30314 can be exposed outside the first guide groove 30223 or not. The first clamping portion 30312a is fixed to the other end of the connecting portion 30314, and the first clamping portion 30312a is exposed outside the first guide groove 30223. The first clamping portion 30312a can be integrally formed with the connecting portion 30314 or fixedly connected to the connecting portion 30314. One end of the elastic portion 30313a is connected to the first clamping portion 30312a, and the other end of the elastic portion 30313a is connected to the connecting seat 3023a. The lower end of the positioning seat 3022 is also provided with a second guide groove 30224 connected to the first guide groove 30223. The second guide groove 30224 extends along the Y direction and is used to install the first clamping portion 30312b. A limiting groove 303141 corresponding to the first clamping portion 30312b is provided on one side of the connecting portion 30314, and one end of the first clamping portion 30312b abuts against the limiting groove 303141. The other end of the first clamping portion 30312b can be exposed outside the second guide groove 30224 and is connected to the elastic portion 30313b. The other end of the elastic portion 30313b is connected to the connecting seat 3023b. The groove surface of the limiting groove 303141 facing the first driving cylinder 30311 is configured as a first limiting inclined surface 3031411, and the first clamping portion 30312b has a second limiting inclined surface 303121 that can abut against the first limiting inclined surface 3031411. When the product 2 needs to be placed on the positioning seat 3022 or removed from the positioning seat 3022, the flip positioning assembly 302 is always in a horizontal position.The piston rod 303112 of the first driving cylinder 30311 is extended, and the first driving cylinder 30311 pushes the connecting part 30314 to move in the first guide groove 30223 along the X direction, thereby pushing the first clamping part 30312a to move in the direction of the connecting seat 3023a along the X direction, and the first clamping part 30312b to move in the direction of the connecting seat 3023b along the Y direction, thereby increasing the distance between the first clamping part 30312a and the first clamping part 30312b and the positioning part 30222, making it easier to place the product 2 on the positioning surface 30221, and also easier to take the product 2 out of the positioning surface 30221. When it is necessary to fix the product 2 on the positioning seat 3022, the piston rod 303112 of the first driving cylinder 30311 is retracted. Under the rebound force of the elastic part 30313a, the first clamping part 30312a moves in the direction away from the connecting seat 3023a along the X direction. Under the rebound force of the elastic portion 30313b, the first clamping portion 30312b moves along the Y direction in a direction away from the connecting seat 3023b, so that the first clamping portion 30312a and the first clamping portion 30312b cooperate with the positioning portion 30222 to clamp the product 2.

[0043] As an example, please refer to Figure 7 The guide body 303131 may be a guide rod, and the spring 303132 abuts between the clamping portion 30312 and the connecting seat 3023. When the piston rod 303112 of the first driving cylinder 30311 extends, the spring 303132 is compressed. When the piston rod 303112 of the first driving cylinder 30311 retracts, the spring 303132 rebounds, pushing the first clamping portion 30312 to move.

[0044] In some examples, in order to enable the first driving cylinder 30311 to push the connecting portion 30314 more effectively and prevent the first driving cylinder 30311 from damaging the connecting portion 30314, a pushing block 30315 is fixed to the output end of the piston rod 303112 of the first driving cylinder 30311, and the piston rod 303112 of the first driving cylinder 30311 can abut against the connecting portion 30314 through the pushing block 30315. The pushing block 30315 is used to directly push the connecting portion 30314 to move.

[0045] In some examples, the product 2 has a through hole 205 that vertically penetrates the product 2. Optionally, the flip positioning assembly 302 is provided with a first clearance hole 3024 that penetrates the flip positioning assembly 302, and the first clearance hole 3024 is arranged corresponding to the through hole 205. Specifically, the first clearance hole 3024 can penetrate the positioning seat 3022 and the flip seat 3021 at the same time. The clamping assembly 303 may include a second clamping member 3032. The second clamping member 3032 includes a second driving cylinder 30321 and a second clamping portion 30322. The cylinder body 303211 of the second driving cylinder 30321 is fixed to the lower end of the flip positioning assembly 302, that is, the lower end of the flip seat 3021, and the piston rod 303212 of the second driving cylinder 30321 is fixed to the second clamping portion 30322. The second clamping portion 30322 is penetrated in the first clearance hole 3024. The piston rod 303212 of the second driving cylinder 30321 can extend upward, so that the second clamping part 30322 extends out of the first clearance hole 3024 and the through hole 205 in sequence, and then the piston rod 303212 of the second driving cylinder 30321 can also rotate around its own axis by a preset angle, for example, 90°, so that the second clamping part 30322 also rotates around the axis of the piston rod 303212 of the second driving cylinder 30321 by the same angle, and then the piston rod 303212 of the second driving cylinder 30321 retracts again, so that the second clamping part 30322 abuts against the front side 203 of the product 2 to press the product 2 against the positioning surface 30221.

[0046] As an example, please refer to Fig. 9 The cross-sectional shape of the through hole 205 is a rectangle, and the cross-sectional shape of the second clamping portion 30322 can be similar to the cross-sectional shape of the through hole 205, and is also a rectangle. It is understandable that the cross-sectional shape of the second clamping portion 30322 can also be different from the cross-sectional shape of the through hole 205. Please refer to Fig.11 , it is sufficient to ensure that the second clamping portion 30322 can extend from the through hole 205 along with the piston rod 303212 of the second driving cylinder 30321, and can abut against the front side 203 of the product 2 after the piston rod 303212 of the second driving cylinder 30321 rotates and retracts.

[0047] As an example, the second driving cylinder 30321 can be a rotary pressing cylinder, which is a prior art and will not be described in detail here. It is understandable that the second driving cylinder 30321 can also be other types of cylinders or replaced by other structures, as long as the piston rod 303212 of the second driving cylinder 30321 can extend upward and rotate around its own axis at a preset angle and then retract, so that the second clamping portion 30322 abuts against the front face 203 of the product 2 to press the product 2 against the positioning surface 30221.

[0048] It is understood that, in some embodiments, the clamping assembly 303 may include a first clamping member 3031. In other embodiments, the clamping assembly 303 may include a second clamping member 3032. In still other embodiments, the clamping assembly 303 may include both the first clamping member 3031 and the second clamping member 3032.

[0049] It is understandable that if the clamping assembly 303 includes both the first clamping member 3031 and the second clamping member 3032. The connecting portion 30314 may be provided with a third clearance hole 303142 that passes through the connecting portion 30314 to make way for the piston rod 303212 of the second driving cylinder 30321. At the same time, in order to prevent the piston rod 303212 of the second driving cylinder 30321 from interfering with the movement of the connecting portion 30314, the third clearance hole 303142 is constructed as an elongated hole extending along the moving direction of the connecting portion 30314, please refer to Fig.12 The piston rod 303212 of the second driving cylinder 30321 is inserted into the third clearance hole 303142.

[0050] In some preferred embodiments, in order to facilitate the flipping of the flip positioning assembly 302, please refer to Figures 2 to 4 The positioning mechanism 3 further includes two support seats 305. The two support seats 305 are symmetrically fixed to the base 301, and the two support seats 305 are rotatably connected to the two ends of the flip positioning assembly 302. Specifically, the two support seats 305 are rotatably connected to the two ends of the flip seat 3021.

[0051] In some preferred embodiments, please refer to Figures 2 to 4 In order to further ensure that the flip positioning assembly 302 will not flip when the protective plug 1 is installed, at least one support seat 305 is connected with a first limiting assembly 306, and the support seat 305 connected with the first limiting assembly 306 is provided with a second clearance hole 3051, which passes through the support seat 305 and is arranged corresponding to the first limiting assembly 306. The first limiting assembly 306 includes a limiting driving member 3061 and a protruding member 3062. The limiting driving member 3061 is fixed to the support seat 305. The protruding member 3062 is fixed to the output end of the limiting driving member 3061, and the protruding member 3062 is penetrated through the second clearance hole 3051. The limiting driving member 3061 is used to drive the protruding member 3062 to pass through the second clearance hole 3051 and insert into the flip positioning assembly 302 in the vertical position, so as to limit the flip positioning assembly 302 to the vertical position. After the protection plug 1 is installed, the limit drive member 3061 is also used to drive the protruding member 3062 to withdraw from the flip positioning assembly 302 and retract into the second clearance hole 3051 to prevent the protruding member 3062 from interfering with the flip positioning assembly 302 to flip back to a horizontal position.

[0052] As an example, the limit driving member 3061 may be a cylinder. The limit driving member 3061 may also be other structures, as long as the limit driving member 3061 can drive the extending member 3062 to extend and retract to limit the flip positioning assembly 302 and release the limit to the flip positioning assembly 302.

[0053] For some examples, see Figures 2 to 4 Each support seat 305 is connected to a first limiting assembly 306 , and the first limiting assemblies 306 on the two support seats 305 can be symmetrically arranged.

[0054] For some examples, see Fig.12 The flip seat 3021 is provided with a limiting hole 30211, and the limiting hole 30211 is used to cooperate with the protruding member 3062. When the flip positioning assembly 302 is in the vertical position, the limiting hole 30211 is aligned with the protruding member 3062. Under the drive of the limiting driving member 3061, the protruding member 3062 can pass through the second yielding hole 3051 and be inserted into the limiting hole 30211.

[0055] In some preferred embodiments, please refer to Figure 2 and Fig.11 The positioning mechanism 3 may further include a second limiting assembly 307. The second limiting assembly 307 includes a vertical limiting member 3071 and a horizontal limiting member 3072. The vertical limiting member 3071 is fixed to the base 301 and extends in the vertical direction. When the flip positioning assembly 302 flips to the horizontal position, the vertical limiting member 3071 is used to abut against the flip positioning assembly 302 flipped to the horizontal position, so as to limit the flip positioning assembly 302 to the horizontal position. Fig.11 The horizontal stopper 3072 is fixed to the base 301 and extends in the horizontal direction. When the flip positioning assembly 302 flips to the vertical position, the horizontal stopper 3072 is used to abut against the flip positioning assembly 302 flipped to the vertical position to limit the flip positioning assembly 302 to the vertical position. Figure 2 shown.

[0056] For some examples, see Figure 7 Two rotating shafts 3025 are symmetrically fixed on the flip seat 3021 , and the two rotating shafts 3025 are arranged in a one-to-one correspondence with the two supporting seats 305 , and each rotating shaft 3025 is connected to the corresponding supporting seat 305 through a bearing 308 .

[0057] In one example, a connecting rod 3026 is fixed to one of the rotating shafts 3025, and the flip driving assembly 304 can be a cylinder. The cylinder body 3041 of the flip driving assembly 304 is rotatably connected to the base 301, and the piston rod 3042 of the flip driving assembly 304 is rotatably connected to the connecting rod 3026. When the piston rod 3042 of the flip driving assembly 304 is extended, the piston rod 3042 of the flip driving assembly 304 pushes the connecting rod 3026 to rotate around the axis of the rotating shaft 3025 in the M direction, so that the rotating shaft 3025 and the flip positioning assembly 302 are rotated together around the axis of the rotating shaft 3025 in the M direction to a vertical position, please refer to Figure 3 When the piston rod 3042 of the flip driving assembly 304 is retracted, the piston rod 3042 of the flip driving assembly 304 pulls the connecting rod 3026 to rotate around the axis of the rotating shaft 3025 in the opposite direction of the M direction, so that the rotating shaft 3025 and the flip positioning assembly 302 rotate together around the axis of the rotating shaft 3025 in the opposite direction of the M direction to a horizontal position.

[0058] In some preferred embodiments, please refer to Figure 2 The positioning mechanism 3 also includes a position sensor 309 for detecting whether the flip positioning component 302 is flipped into place, that is, whether it is in a vertical position or a horizontal position.

[0059] For an example, see Figure 2 , a reference plate 3027 is fixed to one of the rotating shafts 3025. When the flip driving assembly 304 rotates, the reference plate 3027 rotates synchronously with the flip driving assembly 304. There are two position sensors 309, namely position sensor 309a and position sensor 309b. Position sensor 309a and position sensor 309b are respectively fixed to the support seat 305. Among them, please refer to Figure 2 As shown, the position sensor 309a is used to detect whether the reference piece 3027 is within the detection range, thereby detecting whether the flip positioning assembly 302 is in the vertical position. Fig.11 The position sensor 309b is used to detect whether the reference piece 3027 is within the detection range, thereby detecting whether the flip positioning component 302 is in a horizontal position.

[0060] In some preferred embodiments, please refer to Figure 1 , Figure 8 and Fig.10 The protective plug assembly machine also includes a transfer mechanism 5. Please refer to Figure 3The transfer mechanism 5 includes a base 501, a transfer drive assembly 502 and a guide rail 503. The guide rail 503 is fixed to the base 501. A slider 3011 is fixed to the bottom of the base 301. The slider 3011 is slidably connected to the guide rail 503. The transfer drive assembly 502 is connected to the base 501 and the base 301 respectively. When the product 2 is fixed to the flip positioning assembly 302, the transfer drive assembly 502 is used to drive the positioning mechanism 3 to move from the manual position to the automatic position, that is, to the bottom of the needle assembly 401. Please refer to Figure 8 and Fig.10 After the protective plug 1 is installed in the assembly hole 202 of the side 201 of the product 2, the transfer drive assembly 502 is used to drive the positioning mechanism 3 to move from the automatic position to the manual position, that is, to move it to be offset from the needle assembly 401, please refer to Figure 1 , making it easy to remove the product 2 with the protective plug 1 installed from the positioning mechanism 3.

[0061] As an example, the transfer drive assembly 502 may be a cylinder. The cylinder of the transfer drive assembly 502 may be fixed to the base 501, and the piston rod of the transfer drive assembly 502 may be connected to the base 301. In other embodiments, the transfer drive assembly 502 may also be other structures, or connected to the base 501 and the base 301 in other ways, which are not limited here and are not described in detail.

[0062] In some preferred embodiments, please refer to Figure 1 , Figure 8 and Fig.10 The protective plug assembly machine further includes a feeding mechanism 6, which includes a feeding table 601, and the feeding table 601 is used to load the protective plug 1. The assembly mechanism 4 also includes a moving assembly 402, and the needle assembly 401 is connected to the moving assembly 402. The moving assembly 402 is used to drive the needle assembly 401 to move along the X direction, the Y direction, and the Z direction so that the needle assembly 401 can take out the protective plug 1 from the feeding table 601. The moving assembly 402 is used to drive the needle assembly 401 to move along the X direction, the Y direction, and the Z direction so that the needle assembly 401 can install the protective plug 1 in the assembly hole 202.

[0063] It is understandable that the needle assembly 401 is a prior art, and the needle assembly 401 can remove the protective plug 1 by vacuum adsorption or other methods. The needle assembly 401 removing the protective plug 1 from the supply table 601 is a prior art and is not limited here, so it will not be repeated.

[0064] In some examples, the side 201 of the product 2 is provided with a plurality of assembly holes 202, and a protective plug 1 needs to be installed in each assembly hole 202. In some preferred embodiments, in order to improve production efficiency, a protective plug assembly machine is used to install the plurality of protective plugs 1 in the plurality of assembly holes 202 of the product 2 one by one, please refer to Figure 1, Figure 8 and Fig.10 , the assembly mechanism 4 includes a plurality of needle assemblies 401, and the needle assemblies 401 are arranged one by one in correspondence with the assembly holes 202 of the product 2. The moving assembly 402 includes an X-direction sliding module 4021, a Y-direction sliding module 4022, and a Z-direction sliding module 4023 connected in sequence, and there are a plurality of Z-direction sliding modules 4023, which are arranged one by one in correspondence with the needle assemblies 401, and each Z-direction sliding module 4023 is respectively connected to the Y-direction sliding module 4022 and the corresponding needle assembly 401. The X-direction sliding module 4021 and the Y-direction sliding module 4022 can drive all the needle assemblies 401 to move to the feeding mechanism 6 at the same time. Under the drive of the corresponding Z-direction sliding module 4023, each needle assembly 401 can be moved along the Z direction to remove the protective plug 1. Then, under the drive of the X-direction sliding module 4021 and the Y-direction sliding module 4022, all the needle assemblies 401 are moved to the top of the positioning mechanism 3 at the same time. Then, each needle assembly 401 can be sequentially installed with the protective plug 1 under the drive of the X-direction sliding module 4021, the Y-direction sliding module 4022 and the Z-direction sliding module 4023. There is no need to take the protective plug 1 back and forth many times, which saves production time and improves production efficiency.

[0065] It is understandable that the X-axis sliding module 4021, the Y-axis sliding module 4022 and the Z-axis sliding module 4023 are all prior arts and are not limited here, so they are not described in detail.

[0066] As an example, the working process of the protective plug assembly machine can be: in the initial state, the positioning mechanism 3 is located at the manual position, and after the front face 203 of the product 2 is positioned upward to the flip positioning assembly 302 located in the horizontal position, the product 2 is clamped by the clamping assembly 303, and then the flip positioning assembly 302 is flipped along the M direction around the axis of the rotating shaft 3025 to a vertical position by the flip driving assembly 304, so that the assembly hole 202 of the side 201 of the product 2 is set upward, which is convenient for the needle assembly 401 to move along the Z direction to install the protective plug 1 into the assembly hole 202, please refer to Figure 1 Then, the positioning mechanism 3 is moved along the X direction by the transfer mechanism 5, so that the positioning mechanism 3 is moved from the manual position to the automatic position. Please refer to Figure 8 As shown. The moving assembly 402 drives the needle assembly 401 to move to the feeding mechanism 6 to take the protective plug 1, and then the moving assembly 402 drives the needle assembly 401 to move to the automatic position, and drives the needle assembly 401 to move along the Z direction to install the protective plug 1 into the assembly hole 202, and the assembly is completed. After the assembly is completed, the transfer mechanism 5 drives the positioning mechanism 3 to move along the X direction to the manual position, please refer to Figure 1As shown, the flip driving assembly 304 then drives the flip positioning assembly 302 to flip around the axis of the rotating shaft 3025 in the opposite direction of the M direction to a horizontal position so that the front side 203 of the product 2 faces upward, and then the clamping assembly 303 releases the product 2, and the product 2 assembled with the protective plug 1 can be removed.

[0067] It is understandable that the positioning mechanism 3 can be first moved along the X direction by the transfer mechanism 5, so that the positioning mechanism 3 is moved from the manual position to the automatic position. Fig.10 and Fig.11 As shown, the flipping driving assembly 304 is used to flip the flipping positioning assembly 302 around the axis of the rotating shaft 3025 along the M direction to a vertical position. After the assembly is completed, the flipping driving assembly 304 can also be used to first drive the flipping positioning assembly 302 to flip around the axis of the rotating shaft 3025 along the opposite direction of the M direction to a horizontal position, and then the transfer mechanism 5 drives the positioning mechanism 3 to move along the X direction to the manual position.

[0068] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
