Description

Technical Field

[0001] This application relates to the field of assembly and processing technology, specifically to a bonding device. Background Technology

[0002] When assembling electronic products, it is often necessary to attach small components to larger components. For example, small components such as adhesive strips, graphite sheets, and reverse adhesive strips are attached to the mid-plate of the electronic product. Depending on the actual assembly requirements, multiple small components may need to be attached to both sides of the larger component. Currently, commonly used bonding equipment can usually only bond to one side of the larger component. Bonding to the other side requires changing to different bonding equipment, resulting in high bonding assembly costs. Furthermore, changing bonding equipment leads to long processing times and low bonding efficiency. Utility Model Content

[0003] In view of the above, it is necessary to propose a bonding device that can simultaneously bond two sides of a first workpiece, resulting in low bonding assembly cost and high bonding operation efficiency.

[0004] This application provides a bonding device for bonding a second workpiece onto a first workpiece, comprising: a frame including a base plate, a back plate, and a top plate, wherein the back plate is disposed on the base plate, and the top plate is disposed on the side of the back plate away from the base plate, and the top plate and the base plate are disposed opposite to each other along a first direction; and a positioning mechanism including a support component, a first positioning component, and a second positioning component, wherein the support component is connected to the back plate and disposed between the base plate and the top plate, the support component is configured to support the first workpiece, and the first positioning component is connected to the support component and configured to push against the first workpiece along a second direction to cooperate with the support component in positioning the first workpiece in the second direction.

Each clamping member includes a connecting arm extending along the third direction and a clamping arm extending along the first direction. The connecting arm is connected to the driving unit, and the clamping arm corresponds to the support component in the third direction. The driving unit is used to drive the two clamping members to move closer or further away from each other, so that the two clamping arms clamp or release the first workpiece along the third direction, thereby positioning the first workpiece in the third direction when the two clamping arms clamp the first workpiece.

[0010] In some embodiments, the drive unit includes a support frame, a gear, a rack, and two threaded shafts. The support frame is disposed on the side of the top plate opposite to the bottom plate.

[0023] The embodiments of this application will be further described below with reference to the accompanying drawings. To facilitate understanding and explanation of the embodiments of this application, a three-dimensional coordinate system is established in some of the drawings, with the Z-axis direction as the first direction, the Y-axis direction as the second direction, and the X-axis direction as the third direction. The X-axis direction, Y-axis direction, and Z-axis direction are perpendicular to each other.

[0024] Please see Figure 1 and Figure 2 This application provides a bonding device 100 for bonding a second workpiece 300 onto a first workpiece 200. The first workpiece 200 can be the mid-plate of an electronic product, such as a mobile phone or tablet. The second workpiece 300 can be a small part to be bonded to the first workpiece 200, such as a tail adhesive strip, graphite sheet, or reverse adhesive strip. In this embodiment, multiple second workpieces 300 need to be bonded to both sides of the first workpiece 200. The bonding device 100 includes a frame 10, a fixing mechanism, and multiple bonding mechanisms 30.

[0025] Specifically, the frame 10 includes a base plate 11, a back plate 12, and a top plate 13. The back plate 12 is disposed on the base plate 11, and the top plate 13 is disposed on the side of the back plate 12 away from the base plate 11, with the top plate 13 and the base plate 11 being arranged opposite to each other along a first direction. The connection of the base plate 11, back plate 12, and top plate 13 forms a robust frame structure, providing a stable support foundation for the entire device. Furthermore, the base plate 11 and top plate 13 do not have connecting structures on their sides in a second direction, allowing for the assembly of first workpieces 200 of different sizes.

[0026] The positioning mechanism 20 includes a support component 21, a first positioning component 22, and a second positioning component 23. The support component 21 is connected to the back plate 12 and disposed between the bottom plate 11 and the top plate 13. The support component 21 is configured to support a first workpiece 200. The first positioning component 22 is connected to the support component 21 and is configured to push against the first workpiece 200 in a second direction to cooperate with the support component 21 in positioning the first workpiece 200 in the second direction. The second positioning component 23 is connected to the top plate 13 and is disposed opposite to the support component 21 on both sides in a third direction. The second positioning component 23 is configured to position the first workpiece 200 in the third direction. By positioning the first workpiece 200 in the second direction with the first positioning component 22 and positioning the first workpiece 200 in the third direction with the second positioning component 23, combined with the support of the support component 21 in the first direction, precise positioning of the first workpiece 200 in three-dimensional space is achieved, which can effectively reduce the positional deviation of the first workpiece 200 during the bonding process and ensure the bonding accuracy.

[0027] Multiple bonding mechanisms 30 are respectively connected to the base plate 11 and the top plate 13. Each bonding mechanism 30 includes a bonding drive 31 and a bonding assembly 32. The bonding drive 31 is connected to the base plate 11 or the top plate 13, and the bonding assembly 32 is connected to the side of the bonding drive 31 near the first workpiece 200. The bonding assembly 32 is configured to connect to the second workpiece 300. The bonding drive 31 is used to drive the bonding assembly 32 to move toward the first workpiece 200 so as to bond the second workpiece 300 to the first workpiece 200. The number of bonding mechanisms 30 can be two, three, four, etc. The specific number and the position of the bonding assembly 30 on the base plate 11 or the top plate 13 can be set according to actual needs and are not limited here. The bonding drive 31 can be a cylinder, telescopic motor, etc. During bonding, the second workpiece 300 can be installed on the bonding assembly 32 first, and then the bonding drive 31 drives the bonding assembly 32 and the second workpiece 300 to move toward the first workpiece 200, thereby bonding the second workpiece 300 to the first workpiece 200.

[0028] The bonding device 100 provided in this embodiment includes a frame 10, which provides stable support for the positioning mechanism 20 and multiple bonding mechanisms 30. The positioning mechanism 20 includes a support component 21, a first positioning component 22, and a second positioning component 23. The support component 21 supports a first workpiece 200. The first positioning component 22 can cooperate with the support component 21 in a second direction to position the first workpiece 200. The second positioning component 23 can position the first workpiece 200 in a third direction. Thus, through the cooperation of the support component 21, the first positioning component 22, and the second positioning component 23, the first workpiece 200 is accurately positioned. Multiple bonding mechanisms 30 are provided and are respectively connected to the bottom plate 11 and the top plate 13 of the frame 10. The bonding component 32 of the bonding mechanism 30 can connect to the second workpiece 300. Under the drive of the bonding drive component 31, the second workpiece 300 is bonded to the first workpiece 200 from the upper and lower sides, effectively reducing bonding assembly costs and improving bonding operation efficiency.

[0029] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The support assembly 21 includes a connecting plate 211, a support plate 212, and a limiting plate 213. The connecting plate 211 is connected to the side of the back plate 12 near the bottom plate 11 and the top plate 13. The support plate 212 and the limiting plate 213 are both connected to the side of the connecting plate 211 away from the back plate 12, and the support plate 212 and the limiting plate 213 are spaced apart along a first direction. The support plate 212 is configured to support the first workpiece 200, and the limiting plate 213 is configured to abut against the side of the first workpiece 200 away from the support plate 212 to limit the first workpiece 200. The connecting plate 211 connects to the back plate 12 and serves to connect the whole and transmit force; the support plate 212 directly supports the first workpiece 200 and provides the main load-bearing capacity; the limiting plate 213 limits the first workpiece 200 from the other side to prevent the first workpiece 200 from shifting during the bonding process. In this embodiment, the limiting plate 213 is disposed above the support plate 212. When the first workpiece 200 is placed, the first workpiece 200 is inserted between the support plate 212 and the limiting plate 213. The support plate 212 cooperates with the limiting plate 213 to clamp the first workpiece 200 in a first direction to ensure the accuracy of the fit.

[0030] In some embodiments, see Figure 1 , Figure 2 and Figure 3The first positioning component 22 includes a receiving shell 221, a sliding post 222, an elastic element 223, a linkage plate 224, and a pushing element 225. The receiving shell 221 is connected to the side of the support plate 212 away from the limiting plate 213. The receiving shell 221 has a receiving cavity 2211. The sliding post 222 slides through the side wall of the receiving shell 221 away from the back plate 12 along the second direction. One end of the sliding post 222 is located inside the receiving cavity 2211, and the other end is located outside the receiving shell 221. The elastic element 223 is located in the receiving cavity 2211 and sleeved on the sliding post 222. The two ends of the elastic element 223 abut against the receiving shell. The inner wall of 221 and the sliding column 222 are disposed at one end of the receiving cavity 2211. The linkage plate 224 is connected to the end of the sliding column 222 that extends out of the receiving cavity 221. One end of the pusher 225 is connected to the linkage plate 224, and the other end corresponds to the side of the support plate 212 and the limiting plate 213 away from the connecting plate 211. The elastic member 223 is configured to push the sliding column 222 into the receiving cavity 2211 to drive the linkage plate 224 and the pusher 225 toward the support plate 212, thereby causing the pusher 225 to push the first workpiece 200 in the second direction to position the first workpiece 200 in the second direction.

[0031] The housing 221 can be a cuboid structure, and its internal housing cavity 2211 can be a cuboid cavity. The sliding column 222 is a columnar structure. In this embodiment, a stop (not shown) is provided at one end of the sliding column 222 located in the housing cavity 2211, so that when the elastic member 223 is sleeved on the sliding column 222, it can abut against the stop. The elastic member 223 can be a spring or the like, and the pushing member 225 can be a rod-shaped structure. To improve the stability of the linkage plate 224 and the pushing member 225 moving in the second direction, there can be two or three sliding columns 222, and two or three elastic members 223 are provided accordingly, with each elastic member 223 sleeved on one sliding column 222.

[0032] When installing the first workpiece 200, the pusher 225 can be pulled away from the support assembly 21 in the second direction for easier installation. At this time, the pusher 225 drives the linkage plate 224 and the sliding column 222 to move. The sliding column 222 cooperates with the inner wall of the accommodating shell 221 to compress the elastic member 223. After the first workpiece 200 is installed between the support plate 212 and the limiting plate 213, the pusher 225 can be released. The elastic member 223 pushes the sliding column 222 into the accommodating cavity 2211, thereby driving the linkage plate 224 and the pusher 225 to move towards the support plate 212. This causes the pusher 225 to push the first workpiece 200 in the second direction to position the first workpiece 200 in the second direction.

[0033] In some embodiments, see Figure 1 , Figure 2 and Figure 3The first positioning component 22 also includes a rotating shaft 226, which is rotatably disposed on the side of the linkage plate 224 away from the sliding column 222 about a second direction. The pushing member 225 is connected to the linkage plate 224 through the rotating shaft 226 so that the pushing member 225 can rotate about the axis of the rotating shaft 226. A limiting protrusion 2251 is provided at the end of the pushing member 225 away from the rotating shaft 226, and the limiting protrusion 2251 extends toward the back plate 12 along the second direction.

[0034] Bearings or similar components can be installed between the rotating shaft 226 and the linkage plate 224 to improve the stability of the rotating shaft 226. By installing the rotating shaft 226, the pushing member 225 can rotate around its axis. When installing the first workpiece 200, the pushing member 225 can be pulled and rotated in a second direction to allow it to clear the gap between the support plate 212 and the limiting plate 213, facilitating the installation of the first workpiece 200. After the first workpiece 200 is placed between the support plate 212 and the limiting plate 213, the pushing member 225 is pulled and rotated, thereby holding and positioning the first workpiece 200. In practical applications, the shape of the first workpiece 200 may vary, and it may even have irregular surfaces or edges. Through the connection of the rotating shaft 226, the pushing member 225 can automatically adjust its pushing angle to better fit the surface of the first workpiece 200, thereby improving the accuracy and reliability of positioning, especially suitable for positioning complex-shaped first workpieces 200.

[0035] The pusher 225 is provided with a limiting protrusion 2251. When the pusher 225 is passively rotated, such as when the pusher 225 rotates around the pivot 226 due to vibration or other reasons, the limiting protrusion 2251 can abut against the first workpiece 200 to prevent the pusher 225 from separating from the first workpiece 200 and improve the stability of positioning the first workpiece 200 in the second direction.

[0036] In some embodiments, see Figure 1 and Figure 2 The second positioning component 23 includes a driving unit 231 and two clamping members 232. The driving unit 231 is disposed on the side of the top plate 13 away from the bottom plate 11. The two clamping members 232 are symmetrically connected to the two sides of the driving unit 231 along a third direction. Each clamping member 232 includes a connecting arm 2321 extending along a third direction and a clamping arm 2322 extending along a first direction. The connecting arm 2321 is connected to the driving unit 231. The clamping arm 2322 corresponds to the support component 21 in the third direction. The driving unit 231 is used to drive the two clamping members 232 to move closer or further away from each other so that the two clamping arms 2322 clamp or release the first workpiece 200 in the third direction, thereby positioning the first workpiece 200 in the third direction when the two clamping arms 2322 clamp the first workpiece 200.

[0037] The drive unit 231 can be a double-headed cylinder, or other automatic or manual drive mechanisms, as long as it can drive the two clamping members 232 to move closer or further apart; no limitation is made here. The clamping members 232 are approximately L-shaped. The drive unit 231 can drive the two clamping members 232 to move synchronously closer or further apart, thereby clamping or releasing the first workpiece 200 along a third direction. This bidirectional clamping design can precisely control the position of the first workpiece 200 in the third direction, ensuring its stability during the bonding process.

[0038] In some embodiments, see Figure 1 and Figure 2 The drive unit 231 includes a support frame 2311, a gear 2312, a rack 2313, and two threaded shafts 2314. The support frame 2311 is located on the side of the top plate 13 away from the bottom plate 11. The gear 2312 is located inside the support frame 2311 and is rotatably connected to the support frame 2311 about a third direction. The rack 2313 is slidably connected to the support frame 2311 along a second direction and meshes with the gear 2312. The two threaded shafts 2314 are respectively connected to the two ends of the gear 2312 along a third direction, and the threads on the two threaded shafts 2314 are opposite in direction. The two threaded shafts 2314 are respectively threadedly connected to the connecting arms 2321 of the two clamping members 232. The rack 2313 is used to drive the gear 2312 and the two threaded shafts 2314 to rotate, thereby driving the two clamping members 232 to move closer or further away from each other.

[0039] The support frame 2311 can be composed of two opposing U-shaped structures. The lower part of the support frame 2311 is rotatably connected to the gear 2312, and the upper part of the support frame 2311 is slidably connected to the rack 2313, thus restricting the direction of movement of the rack 2313. In this embodiment, both connecting arms 2321 are provided with internal threads so that they can be threadedly connected to the corresponding threaded shafts 2314. When positioning the first workpiece 200, the rack 2313 is manually driven to move in the second direction. The rack 2313 drives the gear 2312 to rotate around the third direction, which in turn drives the two threaded shafts 2314 to rotate around the third direction. The two threaded shafts 2314 drive the two connecting arms 2321 to move closer together, which in turn drives the two clamping arms 2322 to move closer together to clamp and position the first workpiece 200. When releasing the workpiece, the gear 2312 is driven to move in the opposite direction, thus moving the two clamping arms 2322 away from the first workpiece 200.

[0040] In some embodiments, see Figure 1 and Figure 2The second positioning component 23 also includes two limiting rods 233, which are respectively disposed on both sides of the top plate 13 along the third direction and extend along the third direction. The two limiting rods 233 correspond one-to-one with the two clamping members 232. Each limiting rod 233 is slidably inserted into the clamping arm 2322 of the corresponding clamping member 232 to restrict the movement direction of the clamping member 232. By setting limiting rods 233 on both sides of the top plate 13 and slidably inserting them into the clamping arms 2322 of the clamping member 232, the movement direction of the clamping member 232 can be precisely restricted, ensuring that the clamping member 232 can only move along the third direction. This effectively prevents the clamping member 232 from shifting or wobbling during movement, ensuring the accuracy and consistency of the clamping action, thereby improving the positioning accuracy of the first workpiece 200 in the third direction.

[0041] In some embodiments, see Figure 1 and Figure 2 The second positioning component 23 also includes two flexible elements 234, which are respectively connected to two clamping arms 2322. Each flexible element 234 is disposed on the side of the corresponding clamping arm 2322 near the support component 21. The flexible element 234 is used to flexibly abut against the first workpiece 200. The flexible element 234 can be urethane or a sponge pad, etc. By setting the flexible element 234, the first workpiece 200 can be flexibly clamped, which can effectively reduce the direct hard contact between the clamping element 232 and the surface of the first workpiece 200, and avoid damage to the surface of the first workpiece 200 caused by excessive clamping force or uneven contact.

[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 4The bonding assembly 32 includes a vacuum disk 321 and a vacuum pump 322. The vacuum disk 321 is connected to the bonding drive 31. Multiple vacuum holes 3211 are provided on the side of the vacuum disk 321 facing away from the bonding drive 31. The vacuum pump 322 is connected to the vacuum disk 321 and to all the vacuum holes 3211. The vacuum pump 322 is configured to draw air through the multiple vacuum holes 3211 to generate a negative pressure on the side of the vacuum disk 321 facing away from the bonding drive 31, thereby adsorbing the second workpiece 300. The bonding assembly 32 uses the vacuum disk 321 and the vacuum pump 322 to generate negative pressure through the vacuum holes 3211 to adsorb the second workpiece 300. This vacuum adsorption method provides a stable adsorption force, ensuring that the second workpiece 300 is firmly fixed on the vacuum disk 321 during the bonding process, avoiding displacement or detachment due to external force or vibration. The multiple vacuum holes 3211 on the vacuum disk 321 can evenly distribute negative pressure, ensuring that the second workpiece 300 is subjected to uniform force during adsorption, thus avoiding deformation or damage caused by insufficient or excessive local adsorption force, and improving the reliability of bonding. After bonding is completed, the vacuum disk 321 can be released to loosen the second workpiece 300, improving production efficiency.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 4 The bonding component 32 also includes a sealing ring 323, which is disposed on the side of the vacuum disk 321 opposite to the bonding drive component 31 and surrounds multiple vacuum holes 3211. The sealing ring 323 can be a rubber ring or the like. By setting the sealing ring 323, the sealing performance between the second workpiece 300 and the vacuum disk 321 can be improved, effectively preventing air leakage between the vacuum disk 321 and the second workpiece 300, thereby improving the sealing performance of vacuum adsorption and enhancing the negative pressure effect.

[0044] The working process of the bonding device 100 provided in this embodiment is roughly as follows:

[0045] First, pull and rotate the pusher 225 in the second direction to make it avoid positioning the support plate 212 and the limiting plate 213. Then, place the first workpiece 200 between the support plate 212 and the limiting plate 213. The support plate 212, in conjunction with the limiting plate 213, can position the first workpiece 200 in the first direction. Next, pull and rotate the pusher 225 so that it faces the side of the first workpiece 200 in the second direction. Release the pusher 225, which, under the traction of the elastic member 223, the sliding column 222, and the linkage plate 224, holds the first workpiece 200, thereby positioning it in the second direction. Then, place the second workpiece 300 on the vacuum disk 321 of the bonding assembly 32. The vacuum disk 321 generates negative pressure through the vacuum pump 322, adsorbing the second workpiece 300 and firmly fixing it on the vacuum disk 321.

[0046] Then, the rack 2313 is driven to move along the second direction, and the rack 2313 drives the gear 2312 to rotate around the third direction. The gear 2312 then drives the two threaded shafts 2314 to rotate around the third direction. The two threaded shafts 2314 drive the two connecting arms 2321 to move closer to each other, and then drive the two clamping arms 2322 to move closer to each other to clamp and position the first workpiece 200. Thus, the first workpiece 200 is positioned in the third direction, thereby completing the positioning of the first workpiece 200.

[0047] Next, the bonding drive 31 drives the vacuum disk 321 to move toward the first workpiece 200. During this movement, the vacuum disk 321 maintains its adsorption on the second workpiece 300. When the bonding assembly 32 moves to a predetermined position, the second workpiece 300 contacts the first workpiece 200 and begins bonding. The vacuum disk 321 continues to adsorb the second workpiece 300, ensuring its stability during bonding. The bonding drive 31 continues to apply pressure to ensure the second workpiece 300 is firmly bonded to the first workpiece 200. After bonding is complete, the vacuum pump 322 stops pumping air, and the vacuum disk 321 releases the second workpiece 300.

[0048] Finally, the drive unit 231 of the second positioning component 23 controls the clamping members 232 to move away from each other, releases the first workpiece 200, pulls the pusher 225 away from the first workpiece 200, and rotates the pusher 225 to avoid the first workpiece 200, so that the first workpiece 200 with the second workpiece 300 attached can be removed from the support plate 212.
