DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Mobile phones are mobile devices that are widely used by people at present. In the production of mobile phones, an important link is frame bonding, that is, bonding adhesive auxiliary materials at the frame of the mobile phone. The adhesive auxiliary material has two functions, one is to bond the frame and the internal components, and the other is to improve the sealing of the mobile phone.

[0035] In the related art, the adhesive auxiliary material is directly pasted on the four frame strips of the frame by hand. Since the adhesive auxiliary material is soft in material, it is easy to bend and twist, and the pasting position is easy to deviate, affecting the bonding effect. Moreover, manual operation is low in efficiency and high in labor intensity. Moreover, when the size of the adhesive auxiliary material is larger than the bonding position of the middle frame, manual bonding is usually required, which is low in efficiency.

[0036] Another method is to use a suction cup to suck the adhesive auxiliary material and paste the position when moving. The part of the adhesive auxiliary material extending out of the suction cup is easy to touch other structures and move relatively with the suction cup, affecting the bonding precision. In order to solve or improve the problem that the adhesive auxiliary material is easy to deviate during pasting, resulting in low pasting precision, the present application provides an adsorption assembly, an adsorption mechanism and a pasting device.

[0037] The embodiments of the present application will be described below in combination with Figures 1 to 8 .

[0038] According to an embodiment of this application, an adsorption component is provided, including an adsorption head 1 and a plurality of limiting components 3.

[0039] Specifically, such as Figures 1 to 4 As shown, the adsorption head 1 is provided with multiple adsorption holes 2, which are arranged along the first direction X and are used to communicate with a vacuum device. Multiple limiting components 3 each include a mounting base 301 and a limiting rod 302. The limiting rod 302 slides within the mounting base 301 along the axial direction of the adsorption hole 2. The multiple mounting bases 301 are connected to the adsorption head 1 and are arranged along the first direction X and disposed on both sides of the multiple adsorption holes 2. A limiting gap 4 is formed between the limiting rods 302 on both sides. The limiting rod 302 is adapted to slide and switch between a first position and a second position. In the first position, the limiting rod 302 extends along the axial direction of the adsorption hole 2 and its end away from the mounting base 301 is higher than the end of the adsorption hole 2. In the second position, the limiting rod 302 retracts along the axial direction of the adsorption hole 2 and its end away from the mounting base 301 is lower than or flush with the end of the adsorption hole 2.

[0040] Multiple adsorption holes 2 adsorb the adhesive material onto the adsorption head 1. Multiple limiting rods 302 are located on both sides of the multiple adsorption holes 2. A limiting gap 4 is formed between two rows of limiting rods 302 arranged along the first direction X. The adhesive material is located within the limiting gap 4. The multiple limiting rods 302 can restrict the movement of the adhesive material and prevent the adhesive material from touching other structures, which would cause relative movement between the adhesive material and the adsorption head 1 and reduce the bonding accuracy of the adhesive material.

[0041] When the adhesive material is adsorbed onto the adsorption head 1, the multiple limiting rods 302 are in the first position. The end of the limiting rod 302 away from the mounting base 301 is higher than the end of the adsorption hole 2, which can limit the adhesive material within the limiting gap 4. As the adsorption head 1 drives the adhesive material closer to the pasting position, the end of the multiple limiting rods 302 away from the mounting base 301 abuts against the part to be pasted and moves from the first position to the second position. When the limiting rod 302 is in the second position, the end of the limiting rod 302 away from the mounting base 301 is located below the end of the adsorption hole 2 or flush with the end of the adsorption hole 2, so that the adsorption head 1 abuts against the part to be pasted, which does not hinder the adhesive material from being pasted on the part to be pasted, thus improving the pasting accuracy.

[0042] Specifically, adhesive strips can be selected as the adhesive auxiliary material.

[0043] In one embodiment, the adsorption head 1 includes a base 101 and an adsorption part 102.

[0044] Specifically, such as Figures 1 to 4As shown, the bottom of the base 101 is provided with a mounting groove 1011, and the groove bottom of the mounting groove 1011 is provided with a ventilation groove 1012. The base 101 is provided with a first channel 1013 communicating with the ventilation groove 1012, and the first channel 1013 is used to communicate with a vacuum device;

[0045] The bottom of the adsorption part 102 is mounted in the mounting groove 1011, and the edge of the adsorption part 102 is sealingly connected with the mounting groove 1011. The adsorption part 102 is provided with a plurality of adsorption holes 2, and the mounting seat 301 is connected to the adsorption part 102. The adsorption part 102 is provided with a plurality of second channels 1021, one end of each second channel 1021 communicates with the ventilation groove 1012, and the other end respectively communicates with the plurality of adsorption holes 2.

[0046] The bottom of the adsorption part 102 is mounted in the mounting groove 1011, and the adsorption part 102 is connected with the base 101 more stably, and the sealing effect between the ventilation groove 1012 and the second channel 1021 is improved. The first channel 1013 communicates with the ventilation groove 1012, and the ventilation groove 1012 communicates with the adsorption holes 2 through the plurality of second channels 1021. The structure is simple, one ventilation groove 1012 can communicate with a plurality of adsorption holes 2, and the adsorption force of each adsorption hole 2 on the adhesive strip can be ensured to be the same, thereby improving the stability of the adhesive strip adsorbed on the adsorption part 102.

[0047] It should be noted that, as shown in Figure 2 and Figure 6 A third connecting hole 8 is arranged on the base 101, and an auxiliary hole 7 is arranged along the axis perpendicular to the third connecting hole 8, which facilitates the processing of the first channel 1013.

[0048] In one embodiment, the adsorption part 102 is provided with a plurality of mounting holes, and a plurality of mounting seats 301 are one-to-one mounted in the mounting holes.

[0049] In one embodiment, as shown in Figure 2 and Figure 3 The ventilation groove 1012 extends in the first direction X in an S shape.

[0050] It should be noted that, in order to increase the adsorption force on the adhesive strip, the adsorption holes 2 can be arranged in two rows along the first direction X. In order to enable the two rows of adsorption holes 2 to communicate with the ventilation groove 1012, and in order to facilitate processing, the second channel 1021 is arranged as a straight channel, and in order not to increase the width of the ventilation groove 1012, as shown in Figure 3 the ventilation groove 1012 is arranged in an S shape.

[0051] In one embodiment, as shown in Figure 8As shown, the limiting assembly 3 further comprises an elastic member 303, the mounting base 301 is provided with a guide groove 3011 along the axial direction of the adsorption hole 2, the limiting rod 302 is arranged in the guide groove 3011, the elastic member 303 is arranged in the guide groove 3011 and connected with the groove bottom of the guide groove 3011 at one end and connected with the limiting rod 302 at the other end. Under the elastic force of the elastic member 303, the limiting rod 302 has a tendency to slide from the second position to the first position.

[0052] The adhesive tape is placed on the workbench, the adsorption hole 2 of the adsorption part 102 corresponds to and is close to the adhesive tape, the end of the limiting rod 302 away from the mounting base 301 abuts against the workbench, the limiting rod 302 is slidingly connected in the guide groove 3011, as the adsorption part 102 gradually approaches the workbench, the elastic member 303 is compressed, the limiting rod 302 moves to the groove bottom of the guide groove 3011, that is, moves from the first position to the second position, when the end of the limiting rod 302 away from the mounting base 301 is lower than or flush with the end of the adsorption hole 2, the end face where the adsorption hole 2 is located is attached to the adhesive tape, and the adhesive tape can be adsorbed on the adsorption part 102.

[0053] In the process that the adsorption part 102 moves away from the workbench, the elastic member 303 restores, drives the limiting rod 302 to move from the second position to the first position, so that the end of the limiting rod 302 away from the mounting base 301 is higher than the end of the adsorption hole 2, as Figure 4 shown, so that the two rows of limiting rods 302 form a limiting gap 4, the adhesive tape is limited between the two rows of limiting rods 302, and the adhesive tape is prevented from being too long and touching other structures in the moving process, and the relative position of the adsorption part 102 is changed, which affects the subsequent sticking precision.

[0054] Specifically, the elastic member 303 can be a spring or a spring piece.

[0055] In one embodiment, as Figure 8 shown, the side wall of the limiting rod 302 is provided with a first limiting block 3021, the inner wall of the guide groove 3011 is provided with a second limiting block 3012, and the first limiting block 3021 abuts against the second limiting block 3012 in the state of the limiting rod 302 at the first position to limit the limiting rod 302 from leaving the guide groove 3011.

[0056] The first limiting block 3021 and the second limiting block 3012 can prevent the limiting rod 302 from leaving the guide groove 3011, so that the limiting rod 302 can be telescoped in the guide groove 3011 to switch the limiting rod 302 between the first position and the second position.

[0057] In one embodiment, as Figure 1 and Figure 2As shown, the connecting piece is provided, the adsorption part 102 is provided with a plurality of first connecting holes 5, the groove bottom of the mounting groove 1011 is provided with a plurality of second connecting holes 6 corresponding to the plurality of first connecting holes 5, and the connecting piece is provided in the first connecting hole 5 and the second connecting hole 6 to connect the base 101 and the adsorption part 102.

[0058] The bottom of the adsorption part 102 is mounted in the mounting groove 1011, and the mounting groove 1011 can also play a positioning role. The adsorption part 102 is fixed on the base 101 by the connecting piece provided in the first connecting hole 5 and the second connecting hole 6, which is simple in structure and convenient to install and disassemble.

[0059] Specifically, the connecting piece can be a bolt, the second connecting hole 6 is a threaded hole, and the bolt is screwed through the first connecting hole 5 and the second connecting hole to fix the adsorption part 102 on the base 101.

[0060] In one embodiment, as shown, Figure 4 The adsorption hole 2 is a long hole, and the long hole extends along the first direction X. The shape of the long hole is more matched with the shape of the adhesive tape, which can increase the contact area with the adhesive tape, improve the adsorption force, and improve the stability of the adhesive tape adsorbed on the adsorption part 102.

[0061] Specifically, as shown, Figure 5 and Figure 7 One adsorption hole 2 corresponds to two second channels 1021, which improves the adsorption effect.

[0062] According to the embodiment of the application, in another aspect, an adsorption mechanism is also provided, which comprises a vacuum pump and an adsorption assembly. The vacuum pump is provided with a suction hole, and the suction hole is communicated with a plurality of adsorption holes 2 through a pipeline.

[0063] According to the embodiment of the application, in another aspect, a pasting device is also provided, which comprises a mechanical arm and an adsorption mechanism. The mechanical arm is provided with a connecting end, and the adsorption head 1 is installed on the connecting end.

[0064] In the following, all the above-mentioned solutions are comprehensively described in one embodiment. Figures 1 to 8

[0065] The third connecting hole 8 is sealingly connected with a connecting head, the connecting head is connected with the connecting end of the mechanical arm, and a third channel is provided in the middle of the connecting head and communicated with the first channel 1013. The third channel is communicated with the suction hole of the vacuum pump through a pipeline. After installation, the auxiliary hole 7 is blocked.

[0066] ​The mechanical arm driving base 101 is close to the workbench surface where the adhesive tape is placed. The mechanical arm rotates the base 101, so that a column of suction holes 2 is arranged corresponding to the adhesive tape. The mechanical arm drives the suction part 102 to be close to the adhesive tape, so that the adhesive tape is arranged corresponding to the limiting gap 4. When the end of the limiting rod 302 away from the mounting seat 301 abuts against the workbench surface, with the suction part 102 gradually approaching the workbench surface, the spring is compressed, the limiting rod 302 moves to the groove bottom of the guide groove 3011, that is, from the first position to the second position. When the end of the limiting rod 302 away from the mounting seat 301 is below or flush with the end of the suction hole 2, the end face where the suction hole 2 is located is attached to the adhesive tape. The vacuum pump is started, and the adhesive tape can be adsorbed on the suction part 102.

[0067] In the process of moving the suction part 102 away from the workbench surface, the spring restores, drives the limiting rod 302 to move from the second position to the first position, so that the end of the limiting rod 302 away from the mounting seat 301 is higher than the end of the suction hole 2. The adhesive tape is limited between the two columns of limiting rods 302, preventing the adhesive tape from being too long and touching other structures during movement, and changing the relative position of the suction part 102, affecting the subsequent sticking accuracy.
