[0036] Figure 1 The structure diagram of the attachment device according to the embodiment of the utility model is schematically shown. Figure 1 As shown, the utility model proposes an attachment device. The attachment device in the utility model includes a fixing seat 10, a supporting mechanism 20 and an attaching mechanism 30, the fixing mechanism includes the fixing seat 10 and the supporting mechanism 20, the supporting mechanism 20 is arranged on the fixing seat 10 and has a first positioning space 23 therein, the attaching mechanism 30 includes a pressing component, a connecting component and a suction component, the connecting component is connected to the fixing seat 10 and has a guide hole, the pressing component is connected to the suction component and can drive the suction component to pass through the guide hole toward or away from the first positioning space 23, the suction component can form a second positioning space 324 with the connecting component, the second positioning space 324 is arranged opposite to the first positioning space 23, and the suction component is used to absorb the material in the second positioning space 324.

[0037] According to the attaching device of the utility model, the fixing seat 10 can provide fixed positions for the supporting mechanism 20 and the attaching mechanism 30 respectively, the suction component is arranged in the connecting component and can form a second positioning space 324 with the connecting component, and can absorb the material (such as foam) in the first positioning space 23, and under the drive of the pressing component, the absorbed material (such as foam) can be moved toward the first positioning space 23 to realize the attachment operation of the absorbed material (such as foam) and the material located in the first positioning space 23 (such as the main board 40). The first positioning space 23 of the attaching device of the utility model can limit and position the external shape of the absorbed material (such as foam), and the second positioning space 324 can position the material to be attached (such as the main board 40). Under the condition of ensuring a certain positioning accuracy, the simple pressing operation of the pressing component is adopted to realize the attachment operation of the two materials (such as foam and the main board 40). Compared with the method of using tweezers to clamp foam and attach it to the main board 40 in the prior art, the attachment difficulty is reduced and the working efficiency is improved.

[0038] In some embodiments of the present invention, Figure 1 and 2 As shown, the connecting component includes a connecting member and a first limiting member 322, the connecting member is connected to the fixing seat 10, the first limiting member 322 is arranged between the connecting member and the supporting mechanism 20, the first limiting member 322 has a guide hole, the suction component is provided with the guide hole, and can form a second positioning space 324 with the inner wall surface of the guide hole, the connecting member is provided with a through hole, the pressing component is provided with the through hole and is connected to the suction component. In this embodiment, the first connecting member includes a first connecting portion 3211 and a second connecting portion 3212, the first connecting portion 3211 and the second connecting portion 3212 are arranged in an L-shaped structure, the first connecting portion 3211 is connected to the fixing seat 10, the second connecting portion 3212 is connected to the end of the first connecting portion 3211 away from the fixing seat 10, and the second connecting portion 3212 is located above the first positioning space 23.

[0039] Specifically, in this embodiment, if Figure 1 and 2 As shown, the first stopper 322 is arranged on the side of the second connection part 3212 facing the fixing seat 10, and the first stopper 322 has a guide hole for the suction component to pass through, and the pressing component is passed through the guide hole and connected to the suction component. In the initial state, the end of the suction component away from the pressing component is located in the guide hole and forms a second positioning space 324 with the inner wall surface of the guide hole. The operator can place the foam in the second positioning space 324 for positioning, and can absorb the foam through the suction component. Under the subsequent pressing operation of the pressing component, the foam in the second positioning space 324 can be pushed out of the guide hole and attached to the main board 40 of the first limit space.

[0040] Specifically, in this embodiment, if Figure 2 As shown, the connecting assembly further includes a second stopper 323, which is connected to the connecting member and spaced apart from the first stopper 322. The structure of two stoppers enables the mainboard 40 to perform multiple foam attachment operations, thereby improving versatility. Specifically, in this embodiment, Figure 1 and 2 As shown, two suction assemblies are provided, and the first limiting member 322 and the second limiting member 323 are respectively connected to one suction assembly.

[0041] In some embodiments of the present invention, Figure 1 and 2 As shown, the fixing seat 10 is provided with a first support platform 11, and the connecting member is rotatably connected to the first support platform 11. In this embodiment, the first support platform 11 is connected to the first connecting portion 3211, and the first connecting portion 3211 is rotatably connected to the first support platform 11, so that the connecting member and the attaching mechanism 30 can be rotated to the side of the first support platform 11 away from the supporting mechanism 20, so that the second positioning space 324 faces upward, which is convenient for the operator to match the foam with the second positioning space 324.

[0042] In some embodiments of the present invention, Figure 2 As shown, a first detection switch 111 is provided on one side of the first support platform 11 facing the support mechanism 20, and the connecting member has a first rotation state and a second rotation state. When in the first rotation state, the connecting member abuts against the first detection switch 111, and the pressing direction of the pressing component is perpendicular to the first direction. When in the second rotation state, the connecting member is disconnected from the first detection switch 111, and the pressing direction of the pressing component is set at an acute angle to the first direction. The first direction is the arrangement direction of the first positioning space 23 and the second positioning space 324. In this embodiment, since the connecting member is rotatably connected to the first support platform 11, the connecting member can have a first rotation state and a second rotation state. When in the first rotation state, the first detection switch 111 is in contact with the connecting piece, which can not only support the connecting piece in the first rotation state, but also enable the first detection switch 111 to detect the signal at this time. At this time, the pressing direction of the pressing component is set perpendicular to the first direction, that is, the suction component is located directly above the first positioning space 23. Next, the suction component can be driven by pressing the pressing component, so that the foam of the second positioning space 324 is attached to the mainboard 40 of the first positioning space 23.

[0043] Specifically, when in the second rotation state, the first detection switch 111 is disconnected from the connecting piece, and the first detection switch 111 cannot detect the signal at this time. The pressing direction of the pressing component is set at an acute angle to the first direction, and the suction component is not located directly above the first positioning space 23, which is not convenient for the attachment operation of the foam and the main board 40. The above process is to rotate the connecting piece and the suction component, and cooperate the foam with the operation in the second positioning space 324.

[0044] In some embodiments of the present invention, Figure 1 and 2 As shown, a second support platform 12 is provided on the fixing seat 10, and the second support platform 12 is provided on the side of the supporting mechanism 20 away from the first support platform 11, and the second support platform 12 can abut against the connecting member. In this embodiment, when the connecting member reaches the first rotation state, the second support platform 12 can abut against the second connecting portion 3212 of the connecting member, which can further ensure the stability of the connecting member in the first rotation state.

[0045] In some embodiments of the present invention, Figure 4 and 7 As shown, the pressing assembly includes a pressing member 311, a connecting rod 312 and an abutting member 313. The connecting rod 312 is movably arranged in the connecting member. One end of the connecting rod 312 extends to the outside of the connecting member and is connected to the pressing member 311. The other end of the connecting rod 312 is connected to the abutting member 313. The abutting member 313 is connected to the suction assembly. In this embodiment, two connecting rods 312 are provided. The two connecting rods 312 are movably arranged in the guide holes of the second connecting portion 3212 of the connecting member. One end of the two connecting rods 312 is connected to the pressing member 311 at intervals, and the other end of the two connecting rods 312 is connected to the abutting member 313.

[0046] Specifically, the abutment member 313 in this embodiment is a plate-shaped structure, the abutment member 313 is connected to the suction assembly, and as the operator presses the pressing member 311 , the abutment member 313 drives the suction assembly to move toward the first positioning space 23 .

[0047] Specifically, in this embodiment, an elastic return member, such as a spring, can be sleeved on the outside of the connecting rod 312. One end of the elastic return member is connected to the pressing member 311, and the other end of the elastic return member is connected to the connecting member. This enables the pressing assembly to have an initial position, and after the operator presses the pressing member 311, a reverse supporting force is provided to facilitate the recovery of the pressing member 311.

[0048] In some embodiments of the present invention, Figure 4 and 7As shown, the abutment member 313 is provided with a perforation, and the suction assembly can be slidably inserted into the perforation. The side of the abutment member 313 facing away from the connecting member is provided with an elastic member 35, and the elastic member 35 is sleeved on the suction assembly. One end of the elastic member 35 is connected to the suction assembly, and the other end of the elastic member 35 is connected to the abutment member 313. In this embodiment, the elastic member 35 can be a spring, and the elastic member 35 is sleeved outside the suction assembly. When the abutment member 313 drives the suction assembly through the elastic member 35, the elastic member 35 can first absorb a certain driving force, which can ensure that the pressing force is reduced to a certain extent, and prevent the problem that the foam and the main board 40 are attached with a large adhesion force to cause damage to the main board 40.

[0049] Specifically, Figure 4 and 7 As shown, a slide rail 32111 is provided on the first connection part 3211, and the slide rail 32111 is slidably provided on the first connection part 3211. The slide rail 32111 is connected to the first limiting member 322 and / or the second limiting member 323, and can ensure the accuracy of the movement direction of the first limiting member 322 and / or the second limiting member 323.

[0050] In some embodiments of the present invention, Figure 5 and 6 As shown, the suction assembly includes a suction nozzle 332 and a connecting tube 331. The connecting tube 331 is movably inserted into the connecting member and one end of the connecting tube 331 is connected to the suction nozzle 332. The elastic member 35 is sleeved outside the connecting tube 331, and the two ends of the elastic member 35 are respectively connected to the suction nozzle 332 and the abutment member 313. In this embodiment, the other end of the connecting tube 331 is connected to an external air pump and other components. The suction nozzle 332 is inserted into the guide hole and can form a second positioning space 324 with the inner wall of the guide hole. When the operator places the foam into the second positioning space 324, the suction nozzle 332 can absorb and fix it, and then the foam can be pushed to the first positioning space 23 under the drive of the pressing member 311 to achieve the attachment operation.

[0051] Specifically, the suction nozzle 332 is provided with an air hole, which can be connected to an external air pump through the connecting tube 331, so that the foam can be adsorbed by negative pressure and can ensure that the foam does not fall off.

[0052] Specifically, in this embodiment, a negative pressure sensor is provided in the connecting tube 331 , which can check the negative pressure change of the negative pressure sensor to ensure that the foam is placed on the main board 40 .

[0053] In some embodiments of the present invention, Figure 2As shown, a fixing platform 34 is provided on the side of the connecting member facing away from the fixing seat 10, and a first mounting groove 341 is provided on the side of the fixing platform 34 facing the pressing component, and a second detection switch 342 is provided in the first mounting groove 341, and the second detection switch 342 can abut against the pressing end of the pressing component. In this embodiment, when the pressing member 311 is pressed down to a certain extent, it can abut against the second detection switch 342, which indicates that the foam has been attached to the main board 40, that is, the attachment operation is completed. The second detection switch 342 can ensure that the foam and the main board 40 are attached in place without generating a large pressure or a small pressure.

[0054] In some embodiments of the present invention, Figure 3 As shown, the support mechanism 20 includes a support member 21 and a plurality of limit blocks 22, the plurality of limit blocks 22 are sequentially arranged around the circumference of the support member 21, and a first positioning space 23 is formed between the plurality of limit blocks 22 and the support member 21. In this embodiment, the support member 21 is used to support the mainboard 40, and the plurality of limit blocks 22 can position the mainboard 40 on the support plate to ensure the accuracy of the positioning of the mainboard 40.

[0055] Specifically, in this embodiment, the mainboard 40 and the plurality of limit blocks 22 are clearance-matched, and the single-side clearance is 0.1 mm.

[0056] Specifically, in this embodiment, a second mounting groove is provided in the support member 21, a third detection switch is provided in the second mounting groove, and the third detection switch is arranged opposite to the first positioning space 23. The third detection switch can detect whether the mainboard 40 is installed in place, thereby improving the reliability of the overall attachment process.

[0057] Furthermore, the operation process of the attachment device of the utility model is as follows: the mainboard 40 is placed in the first positioning space 23 in advance, and the third detection switch will detect a signal at this time. After the signal is detected, the connector, the pressing component and the suction component are rotated to the second rotation state. Since the suction nozzle 332 is inserted into the guide hole, it can form a second positioning space 324 with the inner wall surface of the guide hole. The foam is placed in the second positioning space 324, and the suction nozzle 332 can adsorb the back of the foam, wherein the shape of the guide hole matches the shape of the foam, and the guide hole and the foam are clearance-matched, and the single-side clearance is 0.1mm. Then the connector, the pressing component and the suction component are rotated to the first rotation state, and the second positioning space 324 is located directly above the first positioning space 23. Then, the pressing piece 311 is pressed manually or automatically to push the bonding surface of the foam onto the main board 40 of the first positioning space 23. When the pressing piece 311 abuts against the second detection switch 342, a signal indicating that the attachment is complete is received. At this time, the adsorption force of the suction nozzle 332 is canceled, thereby realizing the attachment operation between the main board 40 and the foam.

[0058] Afterwards, the connecting member, the pressing component and the suction component are rotated to the second rotation state, so that the attached main board 40 and the foam can be taken out, and the attachment operation of the next foam and the next main board 40 can be carried out.

[0059] Furthermore, in this embodiment, the attaching device can be used for foam attaching operations with high attaching accuracy, and the attaching accuracy can be controlled within 0.2mm. The operation is simplified, the requirements for proficiency are reduced, and the operation efficiency is improved. At the same time, the attaching accuracy is high and can be controlled within 0.2mm. Compared with manual inspection, it can save 5s, the yield can reach 100%, and the quality assurance is high.

[0060] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
