Description

Technical Field

[0001] This utility model relates to the field of bonding equipment technology, and in particular to a bonding device. Background Technology

[0002] Nowadays, after a workpiece completes all its manufacturing processes, operators typically manually apply a protective film to both the top and bottom surfaces (for example, applying Mylar film to both sides of a mobile phone's mid-plate) to prevent scratches or contamination during subsequent transport or assembly. However, during manual film application, the workpiece is prone to bending due to uneven stress, and air bubbles often remain between the film and the workpiece, leading to a reduced bonding yield. Utility Model Content

[0003] In view of the above situation, it is necessary to provide an attachment device to improve the attachment quality.

[0004] This application provides an attachment device, including: Base; The support assembly includes an adsorption element, a support element, and an elastic element. The adsorption element is movably disposed on one side of the base and configured to adsorb a first membrane. The support element is movably inserted through the adsorption element in the direction from the adsorption element to the base and is movably connected to the adsorption element. The end of the support element away from the adsorption element is used to support the workpiece. The elastic element is connected to the adsorption element and the support element respectively.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 This application provides an attachment device 100, which includes a base 10, a support component 20, a rotating component 30, and a lifting component 40. The attachment device 100 is used to attach a first film and a second film to the upper and lower sides of a workpiece 200, respectively. The workpiece 200 can be a mobile phone mid-plate, and the first and second films can be of the same type or different types.

[0024] Please see Figure 2 and Figure 3The supporting component 20 includes an adsorption member 21, a supporting member 22, and an elastic member 23. The adsorption member 21 is movably disposed on one side of the base 10 and configured to adsorb a first membrane. The supporting member 22 is movably inserted through the adsorption member 21 in the direction from the adsorption member 21 to the base 10 and is movably connected to the adsorption member 21. The end of the supporting member 22 away from the adsorption member 21 is used to support the workpiece 200. The elastic member 23 is connected to the adsorption member 21 and the supporting member 22 respectively. The rotating component 30 includes a rotating drive member 31 and a suction member 32. The rotating drive member 31 is disposed on one side of the adsorption member 21 and connected to the suction member 32. The suction member 32 is configured to adsorb a second membrane and, driven by the rotating drive member 31, moves the second membrane above the workpiece 200. The lifting assembly 40 is disposed on the base 10 and connected to the adsorption member 21. The lifting assembly 40 is used to lift the adsorption member 21 and move it along the base 10 in the direction pointing to the adsorption member 21, so that the first membrane and the second membrane are sequentially attached to both sides of the workpiece 200. For example, the elastic member 23 can be a spring, and the rotary drive member 31 can be a rotary cylinder.

[0025] In operation, the aforementioned attachment device 100 first places the first film on the adsorption member 21 so that the adsorption member 21 adsorbs the first film, and then places the second film on the adsorption member 32 so that the adsorption member 32 adsorbs the second film, so that the first film and the adsorption member 21, and the second film and the adsorption member 32 are tightly attached; then, the workpiece 200 is placed on the support member 22 so that the workpiece 200 is above the first film, and the rotation drive member 31 drives the adsorption member 32 to rotate so that the second film is above the workpiece 200; finally, the lifting assembly 40 lifts the adsorption member 21 and moves it along the base 10 in the direction pointing to the adsorption member 21 so that the first film and the second film are respectively attached to the upper and lower sides of the workpiece 200. At the same time, the support member 22 is driven by the adsorption member 21 to compress the elastic member 23 to adaptively adjust the pressure generated when the workpiece 200 contacts the first film and the second film, so as to avoid bending or damage to the workpiece 200.

[0026] Thus, the first and second films are adsorbed by the adsorption component 21 and the adsorption component 32 respectively, so as to tightly adhere the first and second films and avoid the formation of air bubbles in the first and second films. Through the cooperation of the bearing component 20, the rotating component 30 and the lifting component 40, the double-sided attachment of the workpiece 200 can be completed in one go, preventing the workpiece 200 from being damaged by large resistance pressure during the attachment operation, thereby improving the attachment quality. In addition, the attachment device 100 can replace manual operation for the attachment operation, improving the attachment efficiency.

[0027] Please see Figure 1 and Figure 2In some embodiments, the base 10 includes a base plate 11 and a fixing member 12. A rotary drive member 31 and a lifting assembly 40 are respectively disposed on both sides of the base plate 11. The fixing member 12 and the rotary drive member 31 are located on the same side, and the fixing member 12 is connected to the base plate 11. The suction member 32 includes a suction solid 321 and a rotating shaft 322. The suction solid 321 is rotatably disposed between the rotary drive member 31 and the fixing member 12. One end of the rotating shaft 322 is connected to the rotary drive member 31, and the other end of the rotating shaft 322 is rotatably connected to the fixing member 12.

[0028] Thus, through the above arrangement, the rotary drive 31 and the fixing member 12 can support the two ends of the rotating shaft 322 respectively, ensuring that the rotary drive 31 drives the rotating shaft 322 to stably drive the suction object 321 to rotate, thereby improving the rotational stability of the suction object 32.

[0029] Please see Figure 1 and Figure 2 In some embodiments, the base 10 further includes a limiting member 13, which is disposed on both sides of the adsorption member 21 along the direction perpendicular to the direction of the rotation drive member 31 pointing to the fixing member 12 and the rotating shaft 322. The limiting member 13 is connected to the substrate 11 and is configured to abut against the adsorption solid 321 rotating toward the adsorption member 21.

[0030] Thus, through the above settings, when the adsorbent 321 rotates toward the adsorption member 21, the limiting member 13 abuts against the adsorbent 321 to limit the rotation angle of the adsorbent 321, so that the second film adsorbed by the adsorbent 321 is parallel to the upper surface of the workpiece 200, ensuring that the second film is stably attached to the upper surface of the workpiece 200, thereby improving the adhesion quality and accuracy.

[0031] Please see Figure 1 and Figure 2 In some embodiments, the base 10 further includes a support member 14, which is disposed on the side of the rotating shaft 322 away from the adsorption member 21 and connected to the substrate 11. The support member 14 is used to support the adsorption solid 321 that rotates away from the adsorption member 21.

[0032] Thus, with the above arrangement, when the adsorbent 321 rotates away from the adsorbent 21, the support 14 abuts against the back of the adsorbent 321, so that the adsorbent 321 and the base 10 form a preset angle, which makes it easy to remove the attached workpiece 200, and at the same time makes it easy to place the second film to be attached to the adsorbent 321, which is beneficial for the attachment device 100 to perform repeated operations.

[0033] Please see Figure 2 and Figure 3In some embodiments, the adsorption member 21 has a receiving groove 211 on the side opposite to the base 10, the elastic member 23 is disposed in the receiving groove 211, and the carrier member 22 includes a carrier body 221 and a guide body 222. The carrier body 221 is movably inserted through the receiving groove 211 in the direction of the adsorption member 21 pointing towards the base 10. The carrier body 221 has an opening groove 2211 and a receiving groove 2212. The opening groove 2211 is disposed on the side wall of the carrier body 221 and is configured to receive part of the workpiece 200 to support the workpiece 200. The receiving groove 2212 is disposed at the end of the carrier body 221 away from the base 10. The guide body 222 is movably inserted through the elastic member 23 and the carrier body 221 in the direction of the adsorption member 21 pointing towards the base 10 and extends to the receiving groove 2212. One end of the guide body 222 is movably connected to the adsorption member 21, and the other end of the guide body 222 is used to abut against the bottom of the receiving groove 2212.

[0034] Thus, through the above-mentioned arrangement, when the workpiece 200 is placed on the carrier 22, the bottom of the opening groove 2211 supports the workpiece 200, so that a certain distance is formed between the workpiece 200 and the first membrane, avoiding premature adhesion between the workpiece 200 and the first membrane during the operation of the lifting assembly 40, which would cause air bubbles to form in the first membrane, thereby ensuring the adhesion accuracy of the first membrane; by limiting the movement direction of the carrier 221 through the guide body 222, the carrier 221 is prevented from shifting when it is compressed by the elastic member 23 under the drive of the adsorption member 21, further improving the adhesion accuracy. At the same time, the end of the guide body 222 away from the adsorption member 21 abuts against the bottom of the receiving groove 2212 to limit the reset distance of the carrier 221 and prevent the carrier 221 from detaching from the adsorption member 21.

[0035] Please see Figure 2 In some embodiments, both the adsorption member 21 and the adsorption member 32 are provided with adsorption positions 323 and positioning bodies 324. The adsorption position 323 is provided with a plurality of adsorption holes 325. The adsorption holes 325 are configured to adsorb the first membrane or the second membrane. The positioning body 324 is disposed adjacent to the adsorption position 323 and is configured to position the release film covering the first membrane or the release film covering the second membrane.

[0036] Thus, through the above settings, the release film is positioned by the positioning body 324 to position the first film body to the adsorption position 323 of the adsorption member 21 and to position the second film body to the adsorption position 323 of the adsorption member 32, avoiding misalignment between the first and second film bodies and the adsorption position 323, thereby ensuring that the first and second film bodies are accurately attached to the preset area of ​​the workpiece 200, thereby improving the attachment accuracy.

[0037] Please see Figure 1In some embodiments, the lifting assembly 40 includes a lifting member 41 and a guide member 42. The lifting member 41 is disposed on the base 10 and connected to the adsorption member 21, and is used to lift the adsorption member 21 in the direction from the base 10 toward the adsorption member 21. The guide member 42 is movably disposed through the base 10 in the direction from the base 10 toward the adsorption member 21 and is connected to the adsorption member 21, and is configured to guide the adsorption member 21. Exemplarily, the lifting member 41 may be a cylinder.

[0038] Thus, through the above configuration, the lifting member 41 provides driving force so that the adsorption member 21 moves along the base 10 in the direction pointing to the adsorption member 21 under the guidance of the guide member 42, thereby ensuring that the first film and the second film are accurately attached to the preset area of ​​the workpiece 200, thereby improving the attachment quality and attachment accuracy.

[0039] Please see Figure 1 In some embodiments, the lifting assembly 40 further includes a connector 43 and a buffer 44. The connector 43 is connected to the end of the guide 42 away from the suction member 21, and the buffer 44 is connected to the connector 43 and is used to abut against the base 10 under the action of the connector 43. Exemplarily, the buffer 44 may be a hydraulic damper.

[0040] Thus, through the above arrangement, the buffer 44 abuts against the base 10 under the action of the connector 43, so as to prevent the adsorption member 21 from moving excessively and causing damage or bending to the workpiece 200, thereby improving the adhesion quality.

[0041] Please see Figure 1 In some embodiments, the attachment device 100 further includes a holding assembly 50, which includes a guide 51, a support 52, a holding member 53, and a holding drive 54. One end of the guide 51 is connected to the base 10, the support 52 is connected to the other end of the guide 51, the holding member 53 is sleeved on the guide 51, and the holding drive 54 is disposed on the support 52 and connected to the holding member 53. The holding drive 54 is used to drive the holding member 53 to hold the rotated suction device 32. Exemplarily, the holding drive 54 can be a cylinder.

[0042] Thus, through the above configuration, the pressing drive 54 provides a driving force to the pressing member 53, so that the pressing member 53 moves close to the suction member 32 under the guidance of the guide member 51, so that the pressing member 53 stably presses the suction member 32, preventing the suction member 32 from being pushed open when the suction member 21 moves along the direction of the base 10 towards the suction member 21, ensuring that the suction member 32 remains stable during the attachment process, thereby improving the attachment stability.

[0043] Please see Figure 1In some embodiments, the holding assembly 50 includes a limiting member 55 and an abutment member 56. The limiting member 55 is disposed on one side of the adsorption member 21 and connected to the base 10. The abutment member 56 is disposed corresponding to the limiting member 55 in the direction from the adsorption member 21 to the base 10. The abutment member 56 is connected to the holding member 53 and is configured to abut against the limiting member 55 under the action of the holding member 53. Exemplarily, the abutment member 56 may be a hydraulic damper.

[0044] Thus, through the above-mentioned arrangement, when the holding member 53 moves close to the suction member 32, the abutting member 56 abuts against the limiting member 55 under the action of the holding member 53, so as to prevent the holding member 53 from excessively pressing the suction member 32 and causing damage or bending of the workpiece 200, thereby improving the adhesion quality.

[0045] The working process of the above-mentioned attachment device 100 is roughly as follows: First, the first membrane is placed on the adsorption member 21 so that the adsorption member 21 adsorbs the first membrane. Then, the second membrane is placed on the adsorption member 32 so that the adsorption member 32 adsorbs the second membrane, so that the first membrane and the adsorption member 21, and the second membrane and the adsorption member 32 are tightly attached. Then, the workpiece 200 is placed on the carrier 22 so that the workpiece 200 is above the first membrane. The rotation drive 31 drives the suction device 32 to rotate the second membrane. The limiting device 13 abuts against the suction device 32 to limit the rotation angle of the suction device 32 so that the second membrane is above the workpiece 200. Finally, the lifting member 41 lifts the adsorption member 21 and moves it along the base 10 towards the adsorption member 21, so that the first film and the second film are respectively attached to the upper and lower sides of the workpiece 200. At the same time, the bearing member 22 compresses the elastic member 23 under the action of the adsorption member 21, so as to adaptively adjust the pressure generated when the workpiece 200 contacts the first film and the second film, avoid bending or damage to the workpiece 200, and thus improve the attachment quality and attachment efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application 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 this application without departing from the spirit and scope of the technical solutions of this application.
