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

[0029] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0030] Please see Figure 1 This application provides a pressing device 100. The pressing device 100 is used to press and hold pressure on a workpiece (not shown) to be pressed, such as a screen assembly or a mobile phone glass back cover after sealing. The pressing device 100 includes a pressing platform 10, a supporting mechanism 20, and a pressing mechanism 30. The pressing platform 10 is used to mount the supporting mechanism 20 and the pressing mechanism 30, enabling the pressing device 100 to achieve a modular design.

[0031] A supporting mechanism 20 is disposed on the pressing platform 10, and the supporting mechanism 20 is used to support the workpiece to be pressed. A pressing mechanism 30 is disposed on the pressing platform 10, and the pressing mechanism 30 includes a pressing assembly 30a disposed above the supporting mechanism 20 (see [link to relevant documentation]). Figure 4 and Figure 5 The pressing assembly 30a includes a first pressing member 31 (see [link to original text]). Figure 4 and Figure 5 ) and the second press-fit part 32 (see Figure 4 and Figure 5The ends of the first pressing member 31 and the second pressing member 32 are joined with a gap, and the first pressing member 31 and the second pressing member 32 can move independently toward or away from the bearing mechanism 20. Here, "gap joining" can be understood as the ends of the first pressing member 31 and the second pressing member 32 being adjacent but not in contact with each other, and the first pressing member 31 and the second pressing member 32 being able to move independently without interfering with each other.

[0032] In this embodiment, the first pressing member 31 and the second pressing member 32 are joined together to form a ring structure. The workpiece can be a screen assembly, and the ring structure can correspond to the frame of the screen assembly. The first pressing member 31 and the second pressing member 32 are used to press against the surface of the workpiece, and the pressing surfaces of the first pressing member 31 and the second pressing member 32 are adapted to the workpiece. As an example, the first pressing member 31 can be approximately U-shaped, and the second pressing member 32 can be approximately strip-shaped. It is understood that in other embodiments, the shapes of the first pressing member 31 and the second pressing member 32 can also be adapted to the shape of the workpiece, and this application embodiment does not specifically limit this.

[0033] Understandably, in other embodiments, for example when the workpiece is an L-shaped component, the first pressing member 31 and the second pressing member 32 can be joined together with a gap to form an L-shaped structure; or, for example, when the workpiece is a U-shaped component, the first pressing member 31 and the second pressing member 32 can be joined together with a gap to form a U-shaped structure. This application does not specifically limit this aspect.

[0034] Thus, in this embodiment, when pressing and holding the workpiece, the pressing device 100 places the workpiece to be pressed on the support mechanism 20; both the first pressing member 31 and the second pressing member 32 move close to the support mechanism 20; when both the first pressing member 31 and the second pressing member 32 press against the workpiece, according to the structural differences at various positions on the workpiece, the first pressing member 31 and the second pressing member 32 move independently to adapt to and press the workpiece with appropriate pressure. The pressures exerted on each position of the workpiece by the first pressing member 31 and the second pressing member 32 can be different, thereby achieving adaptive pressing and holding of each position of the workpiece. The first pressing member 31 and the second pressing member 32 can press the workpiece simultaneously or sequentially; this embodiment does not specifically limit this.

[0035] To avoid any parts of the workpiece that have not been pressed and held under pressure, in this embodiment, please refer to [reference needed]. Figure 5 and Figure 6Both ends of the first pressing member 31 are first stepped portions 311, and both ends of the second pressing member 32 are second stepped portions 321. When the first pressing member 31 and the second pressing member 32 are joined together with a gap, the first stepped portions 311 and the second stepped portions 321 are interlocked with a gap, and the first pressing member 31 and the second pressing member 32 are joined together with a gap to form a ring structure. Each stepped portion can be roughly understood as an L-shaped structure, that is, each stepped portion can be roughly composed of protrusions and grooves formed on the corresponding pressing member. The interlocking and gapped arrangement of each stepped portion can be understood as: the protrusions of each stepped portion are inserted into the grooves of the other. Thus, when the first pressing member 31 and the second pressing member 32 press against the workpiece, the first step portion 311 of the first pressing member 31 can press against the structure of the workpiece to be pressed by the second pressing member 32, and the second step portion 321 of the second pressing member 32 can press against the structure of the workpiece to be pressed by the first pressing member 31, so that the first pressing member 31 and the second pressing member 32 respectively form cross pressing through the first step portion 311 and the second step portion 321, thereby enabling the first pressing member 31 and the second pressing member 32 to relatively seamlessly press and hold each position of the workpiece, avoiding the appearance of unpressed and unheld parts on the workpiece.

[0036] Please see Figure 2 In this embodiment, the pressing mechanism 30 further includes a bracket 33, a first driving component 34, and a second driving component 35. The bracket 33 is disposed on the pressing platform 10. The first driving component 34 and the second driving component 35 are disposed on the bracket 33 at a distance. The first driving component 34 is connected to the first pressing member 31 and is used to drive the first pressing member 31 to move. The second driving component 35 is connected to the second pressing member 32 and is used to drive the second pressing member 32 to move. Thus, by setting the bracket 33, the first driving component 34, and the second driving component 35, the bracket 33 enables the installation of the first driving component 34 and the second driving component 35, and the first driving component 34 and the second driving component 35 enable the movement of the first pressing member 31 and the second pressing member 32.

[0037] To improve the pressing efficiency of the pressing device 100, in this embodiment, the number of the first pressing component 31, the second pressing component 32, the first driving assembly 34, and the second driving assembly 35 can all be two, and they are respectively arranged in a one-to-one correspondence. Both the two first driving assemblies 34 and the two second driving assemblies 35 are mounted on the bracket 33. Thus, by setting the number of the first pressing component 31, the second pressing component 32, the first driving assembly 34, and the second driving assembly 35 to two, the pressing device 100 can simultaneously press and hold pressure on two workpieces. It is understood that in other embodiments, the number of the first pressing component 31, the second pressing component 32, the first driving assembly 34, and the second driving assembly 35 can also be one or more, depending on the actual situation. This application embodiment does not specifically limit this.

[0038] In this embodiment, the bracket 33 includes a support member 331 and a mounting member 332. There can be two support members 331, spaced apart on the pressing platform 10, located on opposite sides of the bearing mechanism 20. The mounting member 332 connects to the top of the two support members 331 and is positioned above the bearing mechanism 20. The mounting member 332 can be composed of a double-layer flat plate structure or a single-layer flat plate structure. The first driving assembly 34 and the second driving assembly 35 are spaced apart from the mounting member 332. Thus, by configuring the specific structure of the bracket 33, the first driving assembly 34 and the second driving assembly 35 are mounted, and the first driving assembly 34, the second driving assembly 35, the first pressing member 31, and the second pressing member 32 are positioned above the bearing mechanism 20.

[0039] Please refer to the above. Figure 3 and Figure 4 In this embodiment, the first drive assembly 34 includes a first drive member 341, a linkage member 342, and a connecting seat 343. The first drive member 341 can be a linear cylinder, and it is mounted on the mounting member 332 of the bracket 33. The linkage member 342 is connected to the first drive member 341 and is located below the mounting member 332. The connecting seat 343 is connected to the linkage member 342, and the first pressing member 31 is connected to the connecting seat 343 and is located below the connecting seat 343. Thus, by configuring the first drive member 341, linkage member 342, and connecting seat 343, the first drive member 341 drives the linkage member 342, connecting seat 343, and first pressing member 31 to move together, thereby enabling the first drive assembly 34 to drive the first pressing member 31 to move.

[0040] In this embodiment, the second drive assembly 35 includes a second drive member 351, a linkage unit 352, and an assembly 353. The second drive member 351 can be a linear cylinder, and is mounted on the mounting member 332 of the bracket 33, spaced apart from the first drive member 341. The linkage unit 352 is connected to the second drive member 351, located below the mounting member 332, and movably passes through the connecting seat 343. The assembly 353 is connected to the linkage unit 352, and movably passes through the connecting seat 343; that is, both the linkage unit 352 and the assembly 353 movably pass through the connecting seat 343. The second pressing member 32 is connected to the assembly 353, and is located below the assembly 353. The structure of the assembly 353 is adapted to the structure of the second pressing member 32. Thus, by configuring the second driving component 351, the linkage unit 352, and the assembly 353, the second driving component 351 drives the linkage unit 352, the assembly 353, and the second pressing component 32 to move together, thereby realizing that the second driving assembly 35 drives the second pressing component 32 to move. Furthermore, by limiting the linkage unit 352 and the assembly 353 to move through the connecting seat 343, the second pressing component 32 can be gap-fitted with the first pressing component 31 to form a ring structure. The connecting seat 343 also limits the movement of the linkage unit 352 and the assembly 353, ensuring the movement accuracy of the linkage unit 352 and the assembly 353.

[0041] To enable the first pressing member 31 to elastically press against the workpiece and to facilitate adjustment of the pressure exerted by the first pressing member 31 on the workpiece, in this embodiment, the connecting seat 343 includes a lower plate 3432. The lower plate 3432 can be relatively independently moved closer to or further away from the linkage member 342. The lower plate 3432 can be composed of a double-layer flat plate structure or a single-layer flat plate structure. The second pressing member 32 is connected to the lower plate 3432, and the lower plate 3432 is adapted to the second pressing member 32. The first driving assembly 34 also includes a first sensor 344 and an elastic member 345. The first sensor 344 can be a pressure sensor, and the first sensor 344 is disposed on the side of the lower plate 3432 opposite to the second pressing member 32. The elastic member 345 can be a spring, and the elastic member 345 is connected between the first sensor 344 and the linkage member 342.

[0042] Thus, by configuring the lower plate 3432, the first sensor 344, and the elastic member 345, when the first driving member 341 drives the connecting seat 343, the first sensor 344, the elastic member 345, and the first pressing member 31 to press against the workpiece via the linkage member 342, the first pressing member 31 and the lower plate 3432 move towards the linkage member 342 due to the reaction force of the workpiece; the elastic member 345 is compressed, and the elastic member 345 applies pressure to the first sensor 344; the first sensor 344 senses the pressure, and the pressure applied to the workpiece by the first pressing member 31 can be calculated by an external computing device (not shown). Firstly, the elastic member 345 enables the first pressing member 31 to elastically press against the workpiece; secondly, the pressure sensed by the first sensor 344 allows for adjustment of the force by which the first driving member 341 drives the connecting seat 343 and the first pressing member 31, thereby adjusting the pressure of the first pressing member 31 on the workpiece.

[0043] To ensure the moving accuracy of the lower plate 3432, in this embodiment, the connecting seat 343 further includes an upper plate 3431, side plates 3433, guide bearings 3434, and guide members 3435. The upper plate 3431 is connected to the linkage member 342 and is located below the linkage member 342. The lower plate 3432 is spaced below the upper plate 3431. The side plates 3433 can be approximately U-shaped. There are two side plates 3433, spaced apart, located on opposite sides of the upper plate 3431 and the lower plate 3432, respectively. One end of each side plate 3433 is connected to the lower plate 3432, and the other end of each side plate 3433 is located on the side of the upper plate 3431 facing away from the lower plate 3432. Each side plate 3433 is abutting against the upper plate 3431, meaning that the side plate 3433 can stop against the upper plate 3431. An elastic element 345 connects the first sensor 344 and the upper plate 3431. There are four guide bearings 3434 and four guide elements 3435, each corresponding to one another. The four guide bearings 3434 are spaced apart on the upper plate 3431, with each bearing passing through it. One end of each guide element 3435 is connected to the lower plate 3432, and the other end slides through its corresponding guide bearing 3434. Thus, by configuring the upper plate 3431, side plate 3433, guide bearings 3434, and guide elements 3435, the lower plate 3432 and guide elements 3435 move along the guide bearings 3434, ensuring the movement accuracy of the lower plate 3432 and the first sensor 344 relative to the upper plate 3431, thereby improving the pressing accuracy of the first pressing member 31 and the second pressing member 32.

[0044] To ensure the moving accuracy of the connecting seat 343, in this embodiment, the pressing mechanism 30 further includes guide sleeves 36 and guide posts 37. The number of guide sleeves 36 and guide posts 37 can both be four, with each guide sleeve 36 and guide post 37 corresponding one-to-one. The four guide sleeves 36 are spaced apart on the mounting parts 332 of the bracket 33, and each guide sleeve 36 passes through the mounting parts 332 of the bracket 33. One end of each of the four guide posts 37 is connected to the upper plate 3431 of the connecting seat 343, and the other end of each guide post 37 slides through the corresponding guide sleeve 36. Thus, by setting the guide sleeves 36 and guide posts 37, the connecting seat 343 and guide posts 37 move along the guide sleeves 36, thereby ensuring the moving accuracy of the connecting seat 343 and improving the pressing accuracy of the first pressing member 31 and the second pressing member 32.

[0045] To enable the second pressing member 32 to elastically press against the workpiece and to facilitate adjustment of the pressure exerted by the second pressing member 32 on the workpiece, in this embodiment, the assembly 353 is movably inserted through the lower plate 3432. The linkage unit 352 includes a linkage module 3521, a second sensor 3522, and a buffer 3523. The linkage module 3521 is movably inserted through the lower plate 3432, with one end connected to the second driving member 351 and the other end connected to the assembly 353. The second sensor 3522 is connected to the linkage module 3521, and the buffer 3523 is connected between the second sensor 3522 and the lower plate 3432. Specifically, the linkage module 3521 can be an inverted L-shaped structure, movably inserted through the upper plate 3431 and the lower plate 3432 of the connecting seat 343, with one end connected to the second driving member 351 and the other end connected to the assembly 353. The second sensor 3522 can be a pressure sensor, and it is connected to the linkage module 3521. The buffer 3523 can be a spring, and it is connected between the second sensor 3522 and the upper plate 3431, i.e., the buffer 3523 is connected to the lower plate 3432 through the upper plate 3431. The connecting seat 343 also includes a connecting member 3436, which is positioned above the upper plate 3431. One end of the linkage module 3521 is slidably disposed within the connecting member 3436. Both the second sensor 3522 and the buffer 3523 are disposed within the connecting member 3436, which can be approximately U-shaped.

[0046] Thus, by setting up the aforementioned linkage unit 352, when the second driving member 351 drives the linkage module 3521, the assembly 353, and the second pressing member 32 to press against the workpiece, the second pressing member 32 presses against the workpiece; simultaneously, the linkage module 3521 presses against the second sensor 3522; the second sensor 3522 compresses the buffer member 3523, and the buffer member 3523 applies pressure to the second sensor 3522; the second sensor 3522 senses the pressure, and the pressure applied to the workpiece by the second pressing member 32 can be calculated by an external computing device. Firstly, the buffer member 3523 enables the second pressing member 32 to elastically press against the workpiece; secondly, the pressure sensed by the second sensor 3522 allows for adjustment of the force by which the second driving member 351 drives the linkage module 3521 and the second pressing member 32, thereby adjusting the pressure of the second pressing member 32 on the workpiece.

[0047] Please see Figure 1 and Figure 7 In this embodiment, the supporting mechanism 20 includes a transfer component 21 and a supporting component 22. The transfer component 21 can be a linear module. The transfer component 21 is disposed on the pressing platform 10 and located between two support members 331. The supporting component 22 is connected to the transfer component 21 and moves under the drive of the transfer component 21. Thus, by setting the transfer component 21 and the supporting component 22 as described above, when loading or unloading, the transfer component 21 drives the supporting component 22 away from the pressing mechanism 30 to facilitate loading or unloading; after loading is completed, the transfer component 21 drives the supporting component 22 closer to the pressing mechanism 30 so that the workpiece is located below the pressing mechanism 30 to facilitate pressing and holding the workpiece.

[0048] In this embodiment, the number of supporting components 22 can be two, with each supporting component 22 corresponding to a first pressing member 31 and a second pressing member 32. Correspondingly, the supporting mechanism 20 also includes a mounting plate 23, which is connected to the transfer component 21, and the two supporting components 22 are spaced apart on the mounting plate 23. Thus, by setting the number of supporting components 22 to two, the pressing device 100 can simultaneously press and hold pressure on two workpieces.

[0049] Understandably, in other embodiments, the number of carrier components 22 may be more, and the specific number can be set according to the actual situation.

[0050] In this embodiment, each supporting component 22 includes a top plate 222, limiting members 224, moving members 225, and a power component 226. The top plate 222 is disposed on the mounting member 332, and the top plate 222 is disposed on the transfer component 21 through the mounting member 332. The top plate 222 is used to support the workpiece, and the top plate 222 can be composed of a double-layer plate structure or a single-layer plate structure. There are multiple limiting members 224, which are respectively disposed on adjacent sides of the top plate 222. There are multiple moving members 225, which are respectively slidably disposed on the other opposite sides of the top plate 222. The power component 226 can be a linear cylinder, and there are multiple power components 226 disposed on the top plate 222. The multiple power components 226 are respectively connected to the multiple moving members 225, and the power component 226 is used to drive the corresponding moving member 225 to move closer to or away from the opposite limiting member 224.

[0051] In this embodiment, the number of limiting members 224 can be four, and two limiting members 224 are respectively provided on the adjacent two sides of the top plate 222. The number of moving members 225 can be four, and two moving members 225 are respectively provided on the other adjacent two sides of the top plate 222. The moving members 225 are arranged opposite to the limiting members 224 on the opposite side. The number of power members 226 can be two, and each power member 226 is connected to two moving members 225.

[0052] Thus, by setting the aforementioned supporting component 22, the power component 226 drives the moving component 225 to move closer to the corresponding limiting component 224, so that the limiting component 224 and the moving component 225 surround and position the workpiece, ensuring the positioning accuracy of the workpiece. The shapes of the limiting component 224 and the moving component 225 may be exactly the same or not exactly the same; this embodiment does not specifically limit this.

[0053] In this embodiment, the supporting component 22 further includes a base plate 221 and support columns 223. The base plate 221 is disposed on the mounting member 332, and the top plate 222 is disposed above the base plate 221 at intervals. The number of support columns 223 can be four, with the four support columns 223 disposed at intervals, and each support column 223 is connected between the base plate 221 and the top plate 222. Multiple power components 226 are disposed on the side of the top plate 222 facing the base plate 221. Thus, by setting the base plate 221 and support columns 223 as described above, a space for accommodating the power components 226 is formed between the base plate 221 and the top plate 222 through the support columns 223, which facilitates the assembly of the power components 226. The supporting component 22 has a compact structure and occupies a small area.

[0054] Understandably, in other embodiments, the number of limiting members 224, moving members 225, and power members 226 may be more or fewer, depending on the actual situation. The power member 226 may also be a linkage driver, meaning that the power member 226 can simultaneously drive the moving members 225 on adjacent sides to move in mutually perpendicular directions. This application does not specifically limit this aspect.

[0055] To ensure that the supporting assembly 22 can stably support and fix the workpiece, in this embodiment, the supporting assembly 22 also includes adsorption elements 227. There can be multiple adsorption elements 227, which can be suction nozzles. Multiple adsorption elements 227 are spaced apart on the top plate 222. Each adsorption element 227 is used to communicate with an external negative pressure device. Under the action of the external negative pressure device, each adsorption element 227 can generate negative pressure, allowing multiple adsorption elements 227 to adsorb the workpiece. Thus, by setting the aforementioned adsorption elements 227, the workpiece is fixed to the top plate 222 under the adsorption action of multiple adsorption elements 227. With the cooperation of the limiting element 224 and the moving element 225, the workpiece is fixed and positioned, ensuring that the supporting assembly 22 can stably support and fix the workpiece, reducing the possibility of workpiece defects.

[0056] To improve the pressing accuracy of the first pressing member 31 and the second pressing member 32 on the workpiece, in this embodiment, the first driving assembly 34 further includes a pin 346 (see [link to documentation]). Figure 4 Pins 346 are located on the side of the lower plate 3432 opposite to the upper plate 3431, and there can be two pins 346. Correspondingly, the top plate 222 of the supporting assembly 22 has insertion holes 228, the number of which is equal to the number of pins 346, and the insertion holes 228 are adapted to the pins 346. Thus, by setting the aforementioned pins 346 and insertion holes 228, when the first driving member 341 drives the connecting seat 343 and the first pressing member 31 to approach the supporting assembly 22 via the linkage member 342, the pins 346 are inserted into the insertion holes 228 to ensure that the first pressing member 31 and the second pressing member 32 can accurately press against the workpiece, thereby improving the pressing accuracy of the first pressing member 31 and the second pressing member 32 against the workpiece.

[0057] Understandably, in other embodiments, the number of pins 346 and sockets 228 may be more or fewer, depending on the actual situation.

[0058] The pressing device 100 provided in this application embodiment uses a split first pressing component 31 and a second pressing component 32 to press and hold pressure on different positions of the workpiece. The pressing pressure of both the first pressing component 31 and the second pressing component 32 can be precisely controlled, solving the problem of glue overflow during pressing and holding of the workpiece and improving the pressing yield of the workpiece. Furthermore, the structure of the first pressing component 31 and the second pressing component 32 can be adapted to the bonding area of ​​the workpiece and different bonding pressures, making the pressing device 100 more versatile and improving its versatility. It can meet the process requirements of different positions of the same product and can achieve process variations such as multiple pressures, multiple heights, multiple bonding methods, and multiple pressure heads for the same product, significantly improving process stability.

[0059] The pressing device 100 provided in this application embodiment further achieves flexible sensing pressing of the workpiece through the coordinated cooperation of the first sensor 344, the elastic element 345, the second sensor 3522, and the buffer element 3523; it controls the pressure of the first pressing element 31 and the second pressing element 32 through different pressure sensing feedback, achieving precise pressure control and adaptive pressing for different positions and heights of the workpiece; it can also realize pressure data feedback and data analysis, thereby meeting pressing requirements. In addition, the pressing distance, pressing area, and pressing and holding time of the first pressing element 31 and the second pressing element 32 can be adjusted separately, and the elastic force of the elastic element 345 and the buffer element 3523 can be adjusted, thereby meeting more pressing and holding requirements.
