[0002] With the continuous development and improvement of the theory of automatic intelligent control, as well as the leap-forward progress of modern programmable control, industrial production is becoming more and more inclined to be intelligent, automated, and highly integrated. The manual operation steps are greatly reduced, aiming to free workers from heavy physical labor and inefficient manual work, and at the same time improve the processing precision and processing efficiency of products.

[0003] In the process of assembling and manufacturing electronic products, it is necessary to press and maintain pressure on the flexible cable and back glue of the electronic product to strengthen the adhesion of the product and prevent it from falling off due to insufficient adhesion strength. At present, the heating and pressure maintaining operations of electronic products such as mobile phones are all manually operated, with low labor efficiency, and there are problems such as inconsistent heating and pressure maintaining pressure and difficulty in precise control. Therefore, it is necessary to realize the automated production operation of heating and pressure maintaining to improve the stability of the attached products and the product yield rate to meet the existing market demand.

[0033] It must be understood that when a component is described as "connected" or "coupled" to another component, it may be directly connected or coupled to other components, and intermediate components may appear. On the contrary, when a component is described as "directly connected" or "directly coupled" to another component, there are no intermediate components.

[0034] In addition, although terms such as "first", "second",... are used in this article to describe different elements, this term is only used to distinguish elements or operations described with the same technical term.

[0035] In addition, for the sake of convenience of description, spatial relative terms such as "below", "beneath", "above", "on" and the like may be used in this article to describe the relationship between one element or feature and another (one or more) element or (one or more) feature as shown in the figure.

[0036] Please refer to Figures 1 to 3 , Figure 1is the front isometric view of the pressure-holding device according to the first embodiment of the present application, Figure 2 is the back isometric view and Figure 3 is Figure 2 the partial enlarged view of part A of ; as shown in the figure, the pressure-holding device 1 of this embodiment is mainly applied to the pressing and pressure-holding processes of the cable and the back glue during the assembly and manufacturing of electronic products, such as mobile phones, tablet computers, etc. In this embodiment, the pressure-holding device 1 includes a first carrier component 2, a second carrier component 3, a pressure-holding component 4, a limiting component 5, and a driving component 6. The first carrier component 2 includes a limiting surface 23. The second carrier component 3 is disposed on one side of the first carrier component 2 and is slidably connected to the first carrier component 2 in the height direction. The pressure-holding component 4 is disposed on the second carrier component 3. The pressure-holding component 4 includes a pressure-holding head 41 and an anti-warping pressure-holding head 42 disposed opposite to the pressure-holding head 41. The pressure-holding component 4 presses the electronic product through the pressure-holding head 41. At the same time, during the pressing process of the pressure-holding head 41 on one side of the electronic product, the pressed side of the electronic product will drop. Due to the rigidity of the electronic product S, it usually causes the other side of the electronic product to warp. Therefore, when the pressure-holding head 41 presses down on one side of the electronic product, the anti-warping pressure-holding head 42 presses against the other side of the electronic product. In this way, during the pressing process of the pressure-holding head 41 on one side of the electronic product, the anti-warping pressure-holding head 42 presses on the other side of the electronic product to improve the force balance on both sides of the electronic product and prevent the other side of the electronic product from warping. Both the pressure-holding head 41 and the anti-warping pressure-holding head 42 use rubber-coated heads.

[0037] As described above, the limiting component 5 is disposed on the second carrier component 3. The limiting component 5 includes a limiting member 51. The lower end surface of the limiting member 51 is height-adjustably disposed on the second carrier component 3 and is located above the limiting surface 23. The driving component 6 is disposed on the first carrier component 2. The action end of the driving component 6 is connected to the second carrier component 3. The driving component 6 is configured to drive the pressure-holding component 4 and the limiting component 5 to move up and down through the second carrier component 3. After the driving component 6 drives the pressure-holding component 4 to descend until it abuts against the electronic product and continues to descend, the pressure-holding component 4 presses the electronic product. Then, after the driving component 6 drives the pressure-holding component 4 to continue to descend until the limiting member 51 abuts against the limiting surface 23, at this time, the pressure-holding component 4 is located at the first position, and the limiting member 51 and the limiting surface 23 are in abutting cooperation to limit the pressure-holding component 4 from continuing to descend. At this time, the pressure-holding component 4 presses the electronic product. In this way, the pressure-holding pressure of the pressure-holding component 4 can be adjusted by adjusting the distance between the limiting member 51 and the limiting surface 23, so as to realize the precise control of the pressure-holding pressure of the electronic product.

[0038] In this embodiment, the limiting component 5 further includes a buffer 52. The buffer 52 is disposed on the second bearing component 3 and above the limiting surface 23. The distance between the buffer 52 and the limiting surface 23 is less than the distance between the limiting member 51 and the limiting surface 23. When the pressure maintaining component 4 is in the second position, the buffer 52 is in abutting cooperation with the limiting surface 23. When the pressure maintaining component 4 continues to descend between the first position and the second position, the limiting surface 23 compresses the buffer 52 to slow down the descending speed of the pressure maintaining component 4. In other words, when the limiting component 5 descends, the buffer 52 abuts against the limiting surface 23 prior to the limiting member 51. When the buffer 52 abuts against the limiting surface 23, at this time the pressure maintaining component 4 is in the second position, and the pressure maintaining component 4 continues to descend and compresses the buffer 52 to slow down the descending speed of the pressure maintaining component 4. Thus, the impact force when the pressure maintaining component 4 contacts the electronic product is reduced by the buffer 52, preventing the pressure maintaining component 4 from damaging the electronic product due to excessive speed. The buffer 52 can use an oil buffer.

[0039] The following is a more detailed description of the pressure maintaining device 1 of this embodiment as follows: Referring back to Figures 1 to 3 As shown, the first bearing component 2 includes a first bearing plate 21. The first bearing plate 21 is vertically arranged. The upper end of the first bearing plate 21 includes a limiting groove 211, and the limiting surface 23 is located at the bottom surface of the limiting groove 211, so that the height of the overall structure can be reduced. The first bearing plate 21 is a rectangular plate. In this embodiment, the first bearing component 2 further includes two vertical support plates 22. The two vertical support plates 22 are disposed on the left and right sides of the first bearing plate 21 and are perpendicularly connected to the first bearing plate 21. The first bearing plate 21 is disposed on a frame (such as the frame of an assembly line) or the ground through the two vertical support plates 22.

[0040] Please refer to Figure 4 , which is a partial perspective view of the pressure maintaining device of the first embodiment of the present application; as shown, the second bearing component 3 includes a second bearing plate 31 and a first connecting plate 32. The second bearing plate 31 is arranged parallel to the first bearing plate 21 and is in sliding fit in the height direction. The second bearing plate 31 is a rectangular plate. The first connecting plate 32 is disposed above the limiting surface 23. One end of the first connecting plate 32 is connected to the second bearing plate 31. As Figure 4 shown, the first connecting plate 32 is orthogonally connected to the second bearing plate 31. The other end of the first connecting plate 32 is connected to the driving component 6. The driving component 6 drives the second bearing component 3 to lift and lower through the first connecting plate 32. In this embodiment, please refer to Figure 3, the driving assembly 6 includes a lifting driving member 61 and a guide rail 62. The guide rail 62 is vertically arranged on the first bearing plate 21. The second bearing plate 31 is slidably arranged on the guide rail 62. The operating end of the lifting driving member 61 is connected to the other end of the first connecting plate 32. The lifting driving member 61 drives the second bearing plate 31 to slide along the guide rail 62 by driving the first connecting plate 32 to lift and lower, so as to realize the sliding fit of the second bearing plate 31 and the first bearing plate 21 in the height direction.

[0041] The lifting driving member 61 can use a cylinder. The lifting driving member 61 is arranged on the side of the first bearing plate 21 opposite to the guide rail 62. The limiting member 51 is arranged on the first connecting plate 32 in a spiral manner. The distance between the lower end surface of the limiting member 51 and the limiting surface 23 is adjusted by rotation. The buffer member 52 is arranged on the first connecting plate 32 side by side with the limiting member 51. The lifting driving member 61 drives the buffer member 52 and the limiting member 51 to descend by driving the first connecting plate 32 to descend.

[0042] Refer back to Figures 1 to 4 As shown, the second bearing assembly 3 further includes a second connecting plate 33. The second connecting plate 33 is vertically connected to the side of the second bearing plate 31 opposite to the first bearing plate 21. The second connecting plate 33 and the first connecting plate 32 are respectively located on the left and right sides of the second bearing plate 31. The pressure maintaining assembly 4 is arranged on the second connecting plate 33. The anti-warping pressing head 42 is connected to the side part of the second connecting plate 33. Among them, the pressure maintaining head 41 presses one side of the electronic product, and the anti-warping pressing head 42 presses against the other side of the electronic product. In this way, during the pressing process of the pressure maintaining head 41 on one side of the electronic product, the anti-warping pressing head 42 presses on the other side of the electronic product to improve the force balance on both sides of the electronic product and prevent the other side of the electronic product from warping.

[0043] Please refer to Figure 5 and Figure 6 , Figure 5 is a partial perspective view of the pressure maintaining assembly of the first embodiment of the present application and Figure 6 is Figure 5 the front view of Figure 5One side of the pressure-holding assembly 4 has two pressure-holding heads 41, and the other side has an anti-warping pressure head 42. In the adjustment structure of one of the pressure-holding heads 41, the first guiding connection block 43 is removed to facilitate a more intuitive understanding of the internal structure of the adjustment structure. As shown in the figure, the pressure-holding assembly 4 includes a first guiding connection block 43, an elastic sliding shaft assembly 44, an adjusting member 45, and a pressure sensor 46. The first guiding connection block 43 is fixed to the second connecting plate 33. The elastic sliding shaft assembly 44 is connected to the second connecting plate 33 through the first guiding connection block 43 for lifting and sliding connection. The lower part of the elastic sliding shaft assembly 44 is connected to the pressure-holding head 41. The upper part of the elastic sliding shaft assembly 44 is connected to the adjusting member 45. The adjusting member 45 is configured to adjust the elasticity of the elastic sliding shaft assembly 44 to finely adjust the pressure-holding pressure of the pressure-holding head 41. The pressure sensor 46 is arranged on the elastic sliding shaft assembly 44. The pressure sensor 46 is configured to feedback the force condition of the elastic sliding shaft assembly 44.

The pressure-holding device 1 is arranged on one side of the carrier plate 10. The pressure-holding assembly 4 is located above the carrier plate 10. Here, being located above the carrier plate 10 specifically means being located above one side of the carrier plate 10 rather than directly above, for example Figure 9The pressure-holding assembly 4 shown in the figure is located above the left side of the carrier plate 10 to facilitate pressing and pressure-holding on one side of the electronic product S. When the pressure-holding device 100 of this embodiment is in use, first place the electronic product S on the carrier plate 10, then the positioning mechanism 20 adjusts the position of the electronic product S on the carrier plate 10 and fixes it on the carrier plate 10. Finally, the pressure-holding assembly 4 of the pressure-holding device 1 performs pressing and pressure-holding operations on the electronic product S.

[0045] Please refer to Figure 10 together, which is Figure 9 a partial enlarged view of part B of ; as shown in the figure, in this embodiment, the positioning mechanism 20 includes a fixed positioning member 201, a first positioning assembly 202, a second positioning assembly 203, and a third positioning assembly 204. The fixed positioning member 201 is fixedly arranged on one side of the carrier plate 10. The first positioning assembly 202 includes a first positioning member 2021 and a first driving member 2022. The first positioning member 2021 is arranged on the side of the carrier plate 10 opposite to the fixed positioning member 201. The first positioning member 2021 faces the fixed positioning member 201. As Figure 9 shown, the first positioning member 2021 and the fixed positioning member 201 are located on the left and right sides of the carrier plate 10. The action end of the first driving member 2022 is connected to the first positioning member 2021 to drive the first positioning member 2021 to move relatively closer to or away from the fixed positioning member 201. The first driving member 2022 can use a cylinder. After the electronic product S is placed on the carrier plate 10, the electronic product S is located between the first positioning member 2021 and the fixed positioning member 201. The first driving member 2022 drives the first positioning member 2021 to move relatively closer to the fixed positioning member 201, so that the first positioning member 2021 abuts against one side of the electronic product S and pushes the other side of the electronic product S to abut against the fixed positioning member 201, thus realizing the positioning and fixing of the left and right sides of the electronic product S.

[0046] As described above, the second positioning assembly 203 includes a second positioning member 2031 and a second driving member 2032. The second positioning member 2031 is arranged on the side of the carrier plate 10 adjacent to the fixed positioning member 201.

The third positioning assembly 204 includes a third positioning member 2041 and a third driving member 2042. The third positioning member 2041 is arranged on the side of the carrier plate 10 opposite to the second positioning member 2031. The third positioning member 2041 faces the second positioning member 2031. As Figure 9As shown, the third positioning member 2041 and the second positioning member 2031 are located on the front and rear sides of the carrier plate 10. The action end of the third driving member 2042 is connected to the third positioning member 2041 to drive the third positioning member 2041 to move relatively closer to or away from the second positioning member 2031. Both the second driving member 2032 and the third driving member 2042 use air cylinders. The electronic product S is located between the third positioning member 2041 and the second positioning member 2031. The second driving member 2032 drives the second positioning member 2031 to move relatively closer to the third positioning member 2041 to push the electronic product S to move towards the third positioning member 2041. The third driving member 2042 drives the third positioning member 2041 to move relatively closer to the second positioning member 2031 to push the electronic product S to move towards the second positioning member 2031. In this way, the positioning and fixing of the front and rear sides of the electronic product S are achieved.

[0047] The preferred steps for the positioning mechanism 20 of this embodiment to adjust the position of the electronic product S on the carrier plate 10 and fix it to the carrier plate 10 include: first, place the electronic product S on the carrier plate 10, and the electronic product S is located between the fixed positioning member 201, the first positioning member 2021, the third positioning member 2041 and the second positioning member 2031; the first driving member 2022 drives the first positioning member 2021 to move relatively closer to the fixed positioning member 201, so that the first positioning member 2021 abuts against one side of the electronic product S and pushes the other side of the electronic product S to abut against the fixed positioning member 201 and tighten, and then the first driving member 2022 drives the first positioning member 2021 to return to its original position; the second driving member 2032 drives the second positioning member 2031 to move relatively closer to the third positioning member 2041, so that the second positioning member 2031 abuts against the front side of the electronic product S and pushes the electronic product S to move towards the third positioning member 2041 and tighten; the third driving member 2042 drives the third positioning member 2041 to move relatively closer to the second positioning member 2031, so that the third positioning member 2041 abuts against the rear side of the electronic product S and tightens, and then the third driving member 2042 drives the third positioning member 2041 to return to its original position; the first driving member 2022 drives the first positioning member 2021 to move relatively closer to the fixed positioning member 201, so that the first positioning member 2021 abuts against one side of the electronic product S and tightens; the third driving member 2042 drives the third positioning member 2041 to move relatively closer to the second positioning member 2031, so that the third positioning member 2041 abuts against the rear side of the electronic product S and tightens. In this way, accurate positioning of the electronic product S can be achieved.

The jacking member 30, the carrier plate 10, and the positioning mechanism 20 are disposed between the double-row conveyor belts 40. The double-row conveyor belt 40 is used to convey the electronic product S onto the carrier plate 10. After the double-row conveyor belt 40 conveys the electronic product S onto the carrier plate 10, the jacking member 30 drives the carrier plate 10 to rise and jack up the electronic product S, so that the electronic product S is located on the carrier plate 10. Then, the positioning mechanism 20 adjusts the position of the electronic product S on the carrier plate 10 and fixes it on the carrier plate 10. Finally, the pressure-holding assembly 4 presses and holds one side of the electronic product S, thus realizing the automated production and manufacturing of the electronic product S. Further, please refer to Figure 11 , which is another perspective view of the pressure-holding device according to the second embodiment of the present application; as shown, in this embodiment, a plurality of pressure-holding devices 1 and the corresponding carrier plates 10 and positioning mechanisms 20 are arranged side by side on the conveying path of the double-row conveyor belt 40, so that the assembly line production of the electronic product S can be realized, and the production efficiency can be improved.

[0049] In summary, the present application provides a pressure-holding device and a pressure-holding device. The pressure-holding assembly and the limiting assembly are disposed on the second carrier assembly, and the action end of the driving assembly is connected to the second carrier assembly. The driving assembly drives the pressure-holding assembly and the limiting assembly to move up and down through the second carrier assembly. After the pressure-holding assembly descends until the pressure-holding head abuts against one side of the electronic product to be pressure-held and continues to descend, the pressure-holding head presses the electronic product, and at the same time, the anti-warping pressure-holding head presses against the other side of the electronic product to improve the force balance on both sides of the electronic product and prevent the other side of the electronic product from warping. After the pressure-holding assembly descends until the limiting member abuts against the limiting surface, the limiting member can prevent the pressure-holding assembly from continuing to descend, and the pressure-holding assembly holds the electronic product. In this way, the pressure of the pressure-holding assembly can be adjusted by adjusting the distance between the limiting member and the limiting surface, so as to realize the precise control of the pressure-holding pressure of the electronic product. At the same time, the limiting assembly of the present application further includes a buffer member, and the descending speed of the pressure-holding assembly is slowed down by compressing the buffer member, so as to reduce the impact force when the pressure-holding assembly contacts the electronic product and prevent the pressure-holding assembly from damaging the electronic product due to too fast speed. The present application is provided with an anti-warping pressure-holding head on one side of the pressure-holding head of the pressure-holding assembly. During the process of pressing one side of the electronic product by the pressure-holding head, the anti-warping pressure-holding head presses against the other side of the electronic product to improve the force balance on both sides of the electronic product and prevent the other side of the electronic product from warping.
