Description

Technical Field

[0001] The present application relates to the technical field of tooling manufacturing, and in particular to a pressing head module, a pressing jig module and a pressing device. Background Art

[0002] Electronic devices such as mobile phones and tablets require component shaping before or during assembly to ensure reliable assembly. Pressing equipment is often used to press and shape components. However, these presses often provide poor results, making the desired shaping difficult. Utility Model Content

[0003] The present application provides a pressing head module, a pressing jig module and a pressing device, which can improve the pressing effect of the pressing device on parts to a certain extent, so that the shaping effect of the parts can meet the expectations.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In a first aspect, the present application provides a pressure head module, comprising: a fixed base, a first pressure head, a second pressure head, and an elastic member. The first pressure head is mounted on the fixed base and is movable relative to the fixed base in a first direction; the first pressure head has a first surface and a second surface that are opposite to each other in the first direction, the first surface having a first pressing surface; the second pressure head is fixed to the fixed base and is located on the periphery of the first pressure head; the second pressure head has a second pressing surface, and the second pressing surface and the first pressing surface face the same direction; the elastic member is disposed between the first pressure head and the fixed base, and the elastic member applies an elastic force to the first pressure head from the second surface toward the first surface.

[0006] When the pressing head module is used to press the equipment to be pressed, since the first pressing head is movable relative to the fixed seat, during the process of the second pressing head pressing down, the elastic force between the elastic member and the first pressing head is utilized. On the one hand, it can ensure that during the pressing and shaping process, the first pressing head always applies pressure to the equipment to be pressed, so as to control the flatness of the equipment to be pressed in the area corresponding to the first pressing head, and prevent the part from being deformed when the second pressing head is pressed; on the other hand, it can also ensure that during the pressing process, the first pressing head has a tendency to move away from the equipment to be pressed relative to the second pressing head, and prevent the first pressing head from over-pressing the equipment to be pressed and damaging the equipment to be pressed.

[0007] At the same time, when using this press head module, two different areas of the equipment to be pressed can be pressed simultaneously, avoiding the secondary deformation of the equipment to be pressed that may occur when pressing with only a single press head, improving the pressing effect and enhancing product consistency. At the same time, the first and second press heads press simultaneously, avoiding the technical problem of low production efficiency caused by segmented pressing, thereby improving production efficiency.

[0008] In a possible implementation of the first aspect, the first pressing head includes a rigid connection portion and a flexible portion, the rigid connection portion is movably mounted on a fixed seat, the elastic member is connected between the rigid connection portion and the fixed seat, the flexible portion is fixed to the rigid connection portion, and the surface of the flexible portion facing away from the rigid connection portion is a first surface. Thus, in the first pressing head, the rigid connection portion is connected to the elastic member, and the rigid connection portion has a large rigidity and is not easily deformed, which is beneficial to improving the reliability of the connection between the first pressing head and the elastic member and is also beneficial to the deformation of the elastic member; at the same time, the first surface is set on the flexible portion. Due to the material characteristics of the flexible portion, when pressing, the first pressing surface of the flexible portion can adapt to the shape of the device to be pressed when in contact with the device to be pressed, thereby increasing the contact area between the first pressing head and the device to be pressed and improving the pressing effect on the device to be pressed.

[0009] In a possible implementation of the first aspect, the second pressing head is a rigid member, thereby ensuring the pressing effect of the second pressing head on the device to be pressed made of a rigid material.

[0010] Specifically, the elastic modulus can be greater than or equal to 100 GPa, which is conducive to ensuring the reliability of the second pressing head pressing the device to be pressed.

[0011] In one possible implementation of the first aspect, the second pressing head is annular and surrounds the first pressing head, and the second pressing surface is annular and extends along the circumference of the second pressing head. Thus, the second pressing head can be used to simultaneously press the annular device to be pressed or the annular edge area of the device to be pressed.

[0012] It is worth noting that when the pressing device is used to press other non-annular structures, or the edge area of the device to be pressed is not annular but a section extending from the middle, the second pressing head may also not be annular.

[0013] In one possible implementation of the first aspect, the fixing seat is located on a side of the first pressing head facing away from the first pressing surface, and on a side of the second pressing head facing away from the second pressing surface. This prevents the fixing seat from interfering with the pressing of the first and second pressing surfaces, thereby improving the pressing reliability of the pressing device.

[0014] In one possible implementation of the first aspect, a sliding groove is provided on a surface of the fixed base facing the first pressing head, and the first pressing head is movably connected to the sliding groove; the second pressing head is fixed to an area surrounding the sliding groove on the surface of the fixed base facing the first pressing head. This prevents the fixed base from interfering with the relative movement of the first and second pressing heads.

[0015] In a possible implementation of the first aspect, the first pressure head includes a rigid connection portion and a flexible portion, wherein the rigid connection portion is movably mounted on the chute, the elastic member is connected between the rigid connection portion and the bottom wall of the chute, and the flexible portion is fixed to the rigid connection portion, with the surface of the flexible portion facing away from the rigid connection portion being the first surface. Thus, in the first pressure head, the rigid connection portion is connected to the elastic member, and the rigid connection portion has a large rigidity and is not easily deformed, which is beneficial to improving the reliability of the connection between the first pressure head and the elastic member and facilitating the deformation of the elastic member. Simultaneously, the first surface is disposed on the flexible portion. Due to the material properties of the flexible portion, during pressing, the first pressing surface of the flexible portion can adapt to the shape of the device to be pressed when in contact with the device to be pressed, thereby increasing the contact area between the first pressure head and the device to be pressed and improving the pressing effect on the device to be pressed. Simultaneously, the rigid connection portion is connected to the elastic member, which is beneficial to improving the reliability of the connection between the first pressure head and the fixed seat.

[0016] In one possible implementation of the first aspect, a support boss is provided on an end of the outer circumference of the rigid connection portion away from the flexible portion; a bearing boss is provided on an end of the inner circumference of the chute adjacent to the second pressure head; in the first direction, the support boss and the bearing boss are directly opposite each other, and the support boss is located on a side of the bearing boss facing away from the second pressure head. In this way, the mutual cooperation between the support boss and the bearing boss prevents the first pressure head from slipping out of the chute.

[0017] In one possible implementation of the first aspect, the second surface has a limiting groove, and the elastic member is disposed in the limiting groove. As the elastic member is susceptible to elastic deformation, disposing the elastic member in the limiting groove facilitates smooth assembly of the pressing device and prevents the elastic member from breaking free from between the fixing seat and the first pressing head due to elastic deformation during assembly and pressing.

[0018] Specifically, there may be multiple limiting grooves. There may be multiple elastic members. Each elastic member may correspond to one limiting groove. In this way, the limiting grooves provide partitioned positioning for the elastic members, reducing mutual interference between the elastic members when deforming along the first direction, thereby ensuring a good pressing effect.

[0019] In one possible implementation of the first aspect, the outer edge of the surface of the second pressing head having the second pressing surface is recessed to form a relief step. Thus, during pressing, the relief step can avoid a protruding structure on the supporting structure of the pressing device corresponding to the relief step, thereby preventing the pressing device from damaging the supporting structure of the pressing device and improving pressing accuracy.

[0020] In one possible implementation of the first aspect, the first pressing head has an extreme position relative to the second pressing head. In this extreme position, the first pressing surface is located on the side of the second pressing surface facing away from the second surface. Thus, during the pressing and shaping process, the first pressing surface can contact the device to be pressed before the second pressing surface, pressing and positioning the area of the device to be pressed corresponding to the shape of the first pressing surface. This ensures that when the second pressing head presses the area of the device to be pressed corresponding to the shape of the second pressing surface, no secondary deformation of the remaining parts of the device to be pressed is caused.

[0021] In one possible implementation of the first aspect, a gap is provided between the first pressing head and the second pressing head, and the gap is less than or equal to 0.5 mm. This ensures relative movement of the first pressing head and the second pressing head while preventing bulging and deformation of the device to be pressed at a location corresponding to the gap.

[0022] In a second aspect, the present application provides a pressing jig module, comprising a first pressing head module and a second pressing head module. The first pressing head module is the pressing head module described in the embodiment of the first aspect; the second pressing head module is located on the side of the first pressing head module to which the first pressing surface and the second pressing surface face, and is movable relative to the first pressing head module in a first direction. The surface of the second pressing head module facing the first pressing head module has a bearing surface for bearing the device to be pressed.

[0023] In a third aspect, the present application provides a pressing device comprising the pressing jig module of the second aspect and a driving device. The driving device is connected to a fixed seat to drive the first pressing head module to move relative to the second pressing head module in a first direction; and / or the driving device is connected to the second pressing head module to drive the second pressing head module to move relative to the first pressing head module in the first direction.

[0024] Since the pressing jig module of the second aspect and the pressing equipment of the third aspect provided in the embodiments of the present application include the pressing head module of any of the above technical solutions, the two can solve the same technical problems and achieve the same technical effects.

[0045] The present application provides a laminating device. The laminating device is used to press and shape the components of electronic devices to improve the laminating effect. Specifically, the electronic devices include but are not limited to mobile phones, tablet computers, laptop computers, vehicle-mounted devices, and wearable devices. The electronic devices can be straight-screen devices (such as straight-screen mobile phones) or foldable devices (such as foldable mobile phones).

[0046] In order to more clearly illustrate the specific structure and working principle of the pressing device, the structure of the electronic device is first introduced before introducing the specific structure and working principle of the pressing device.

[0047] See also Figure 1 、 Figure 2 and Figure 3 , Figure 1 A schematic structural diagram of an electronic device 100 provided in an embodiment of the present application; Figure 2 for Figure 1 An exploded view of the electronic device 100 is shown; Figure 3 for Figure 1 The electronic device 100 is shown as a cross-sectional view along line A0-A0. In this embodiment, the electronic device 100 is a tablet phone. Specifically, the electronic device 100 includes a screen 110, a housing assembly 120, a circuit board 140, and a battery 130.

[0048] It should be noted that Figure 1 、 Figure 2 and Figure 3 The following figures and the related drawings only schematically illustrate some components of the electronic device 100, and the actual shapes, sizes, positions and structures of these components are not affected by the present invention. Figure 1 、 Figure 2 and Figure 3 and the limitations of the accompanying drawings below.

[0049] The screen 110 is used to display images, text, videos, etc.

[0050] The housing assembly 120 is used to protect the internal circuit components of the electronic device 100. Figure 2 and Figure 3The housing assembly 120 includes a middle frame 121 and a back cover 122. The middle frame 121 includes a frame 121a and a middle plate 121b. The frame 121a can be annular. For example, the frame 121a can be roughly rectangular. The screen 110 can be fixed to the frame 121a. The middle plate 121b can serve as a supporting skeleton for the electronic device 100. The middle plate 121b is roughly plate-shaped, and the edge of the middle plate 121b is fixedly connected to the inner surface of the frame 121a. The back cover 122 is fixed to the frame 121a and is located on the side of the middle plate 121b facing away from the screen 110. Specifically, the back cover 122 and the middle plate 121b are spaced apart in the thickness direction of the electronic device 100. The middle plate 121b, the back cover 122 and the frame 121a can enclose an internal storage space of the electronic device 100. The circuit board 140 and the battery 130 can be fixed to the middle plate 121b and stored in the storage space.

[0051] Please continue reading Figure 2 and Figure 3 The electronic device 100 further includes a heating device 150. The heating device 150 is a device that can generate heat inside the electronic device 100. For example, the heating device 150 can be a chip such as a system on chip (SOC), a central processing unit (CPU), or a graphics processing unit (GPU), or can be a circuit board 140. When the heating device 150 is a chip, the heating device 150 can be disposed on the circuit board 140.

[0052] Since the heating device 150 will inevitably generate power consumption during operation, in some embodiments, in order to facilitate the heat generated by the heating device 150 to be dissipated outward, the electronic device 100 further includes a heat conducting mechanism 160. The heat conducting mechanism 160 is a vapor chamber (VC). Of course, in other embodiments, the heat conducting mechanism 160 can also be a graphite sheet or a metal sheet. Specifically, as Figure 3 As shown, the heat conducting mechanism 160 is fixed on a surface of the middle plate 121 b facing the screen 110 .

[0053] See also Figure 4 and Figure 5 , Figure 4 is a schematic structural diagram of the heat sink 161, Figure 5 for Figure 4 The cross-sectional view of the heat spreader 161 along the line B0-B0 is shown. The heat spreader 161 includes a central structure 1611 and a skirt 1612 surrounding the edge of the central structure 1611. A vacuum chamber 16111 is formed inside the central structure 1611. The vacuum chamber 16111 can be filled with a cooling medium ( Figure 4and Figure 5 ). Specifically, the heat spreader 161 can be formed by composite processing of a double-layer metal sheet. Exemplarily, the heat spreader 161 may include a first metal sheet 161a and a second metal sheet 161b, and the first metal sheet 161a and the second metal sheet 161b are arranged in a pair in the thickness direction of the heat spreader 161. The middle area of the first metal sheet 161a and the middle area of the second metal sheet 161b are spaced apart to form a middle structure 1611 having a vacuum chamber 16111. The edge of the first metal sheet 161a and the edge of the second metal sheet 161b are stacked to form a skirt 1612.

[0054] To improve the heat dissipation capacity of the vapor chamber 161, the first metal sheet 161a and the second metal sheet 161b can be made of copper. Since copper is relatively expensive, this results in a higher cost for the vapor chamber 161. To reduce the cost of the vapor chamber 161, in some embodiments, the first metal sheet 161a and the second metal sheet 161b are made of steel. Compared to copper, steel is much more rigid and less susceptible to yielding and deformation.

[0055] Since the metal sheets are relatively thin and have poor bending resistance, the skirt 1612 of the first metal sheet 161a and the second metal sheet 161b are deformed to a certain extent relative to the middle structure 1611 during the process of forming the heat spreader 161. As a result, when the heat spreader 161 is fixed to the side surface of the middle plate 121b facing the screen 110, please refer to the following. Figure 3 , the skirt 1612 tends to warp away from the middle plate 121b. At this point, when the screen 110 and the middle frame 121 are assembled together, the warped skirt 1612 is very likely to hit the screen 110. Because the screen 110 has relatively low structural strength and is relatively fragile, the skirt 1612 hitting the screen 110 can easily cause problems such as film marks and bright lines on the screen 110. In particular, when the first metal sheet 161a and the second metal sheet 161b are made of steel, which is relatively rigid, the steel skirt 1612 can significantly damage the screen 110, causing the screen 110 to fail, affecting the overall device yield, and resulting in significant economic losses.

[0056] Therefore, before assembling the screen 110 to the middle frame 121, it is generally necessary to shape the entire middle frame 121 and vapor chamber 161 (i.e., the device to be pressed). Of course, it is also possible to shape the vapor chamber 161 separately before assembling it to the middle frame 121. The purpose of this shaping is to press the skirt 1612 together to prevent the skirt 1612 from warping away from the middle plate 121b.

[0057] It can be seen that the components of electronic devices such as the heat spreader 161 need to be pressed and shaped before or during assembly to ensure smooth assembly between the components. Electronic device components that require pressing and shaping are defined as devices to be pressed. The following takes the heat spreader 161 and the middle frame 121 as an example of the device to be pressed to introduce the specific structure and working principle of the pressing device. It should be noted that the pressing device can also be applied to other devices to be pressed that require pressing and shaping, such as back covers, middle frames, or other components of electronic devices.

[0058] To shape the equipment to be pressed, please refer to Figure 6 , Figure 6 The present invention provides a structural diagram of a laminating device 500 according to some embodiments of the present application. In this embodiment, the laminating device 500 includes a supporting platform 510 , a support frame 520 , a driving device 530 and a laminating jig module 540 .

[0059] The carrier 510 serves as the structural "skeleton" of the laminating device 500, and is used to support and fix the support frame 520, the driving device 530, and the laminating jig module 540. The laminating device 500 can be supported on a supporting surface (such as the ground or a table) by the carrier 510.

[0060] The supporting platform 510 includes, but is not limited to, a cube, a cylinder, or a special shape. The material of the supporting platform 510 includes, but is not limited to, metal or plastic.

[0061] The support frame 520 is connected to the carrier platform 510. The connection between the support frame 520 and the carrier platform 510 includes, but is not limited to, welding, screw connection, clamping or gluing.

[0062] The shape of the support frame 520 includes, but is not limited to, a rod, a column, a plate, or any combination of at least two of the three. The material of the support frame 520 includes, but is not limited to, metal or plastic. The driving device 530 is fixed to the support frame 520.

[0063] The pressing jig module 540 includes a first pressing head module 540a and a second pressing head module 540b. The first pressing head module 540a and the second pressing head module 540b are arranged opposite to each other in the first direction X.

[0064] The first pressing head module 540a is connected to the driving device 530. The driving device 530 is used to drive the first pressing head module 540a to move along the first direction X. It is worth noting that the first direction X can be the direction of gravity. Of course, the first direction X may not be the direction of gravity.

[0065] See also Figure 7 , Figure 7 Based on Figure 6The first pressing head module 540a includes a fixing base 543 and a pressing head.

[0066] The first pressure head module 540a is connected to the driving device 530 by means of a fixing base 543. There are two pressure heads, and the two pressure heads are independent separate structural parts. The structures of the two pressure heads are different. Specifically, one of the pressure heads (called the first pressure head 541, Figure 7 The second pressure head 542 is configured to engage with the skirt 1612 of the vapor chamber 161. The second pressure head 542 may be annular. Each pressure head is detachably mounted on the fixing seat 543.

[0067] The second pressure head module 540b is fixed on the surface of the supporting platform 510 facing the first pressure head module 540a. The surface of the second pressure head module 540b facing the first pressure head module 540a has a bearing surface. The bearing surface is used to support the device to be pressed (that is, the heat spreader 161 and the middle frame 121 as a whole). Exemplarily, the bearing surface can be at least contoured to the outer contour of the middle frame 121 to facilitate contoured support of the heat spreader 161 and the middle frame 121 as a whole. Of course, in other examples, the shape of the bearing surface may not be similar to that of the device to be pressed, for example, the bearing surface is a plane.

[0068] When the pressing device 500 of the embodiment of the present application is used to shape the pressing device, please continue to refer to Figure 7 First, the device to be pressed can be placed on the supporting surface of the second pressing head module 540b. Then, the control driving device 530 drives the first pressing head module 540a with the second pressing head 542 to move closer to the device to be pressed, so as to press the skirt 1612 so that the skirt 1612 is deformed in the direction close to the middle plate 121b. After shaping, the following can be obtained: Figure 7 The skirt 1612 is indicated by the dotted line.

[0069] Since the second pressing head 542 is annular, the area enclosed by the inner circumference of the second pressing head 542 forms a force-free space region Q. During the pressing process, please continue to refer to Figure 7, the force-free spatial region Q corresponds to the middle structure 1611. Therefore, during the pressing process, the middle structure 1611 will not be subjected to pressure from the second pressure head 542. And before pressing, the skirt 1612 is in a suspended state. In this way, as the skirt 1612 is pressed by the second pressure head 542, the force acting on the skirt 1612 will inevitably be transmitted to the surrounding of the skirt 1612. The force transmitted to the side of the skirt 1612 close to the middle structure 1611 can easily cause the connection between the middle structure 1611 and the skirt 1612 to produce a raised ridge P toward the side where the second pressure head 542 is located. Therefore, in order to ensure the flatness of the heat spreader 161, the heat spreader 161 needs to be pressed a second time to eliminate the raised ridge P.

[0070] Before the secondary pressing, the second pressing head 542 on the fixed seat 543 is replaced with the first pressing head 541. In order to press the raised portion P caused by the first pressing and not damage the vacuum chamber 16111 in the middle structure 1611, the first pressing head 541 is made of a flexible material. During the secondary pressing process, the control drive device 530 drives the first pressing head module 540a having the first pressing head 541 to move in the direction close to the device to be pressed. The first pressing head 541 covers the middle structure 1611 and the raised portion P to perform a large-area secondary pressing of the raised portion P caused by the first pressing to ensure the flatness of the area on the upper surface of the heat spreader 161 surrounded by the skirt 1612.

[0071] The above analysis reveals that when using the aforementioned laminating device 500 for laminating and shaping, the initial laminating process only partially laminarizes the device to be pressed (i.e., skirt 1612), causing secondary deformation of the device to be pressed and resulting in poor laminating results. Therefore, a secondary laminating process is necessary. The presence of a secondary laminating process complicates the entire laminating process, resulting in low production efficiency and affecting the consistency of the finished product.

[0072] In order to solve the technical problems existing in the above-mentioned pressing equipment, the present application provides a pressing fixture module from the perspective of simultaneously installing the first pressing head and the second pressing head together with the fixing base. Figure 8 and Figure 9 , Figure 8 A three-dimensional diagram of a pressing jig module 540 provided in some other embodiments of the present application. Figure 9 Based on Figure 8 The exploded view of the pressing jig module 540 is shown. In the pressing jig module 540, the first pressing head module 540a is improved. Specifically, the first pressing head module 540a includes: a fixed seat 543, a first pressing head 541, a second pressing head 542 and an elastic member (not shown).

[0073] The fixing seat 543 is in the shape of a flat plate or a block. The shape of the fixing seat 543 includes but is not limited to a cube, a cylinder, a prism or a special shape. The material of the fixing seat 543 includes but is not limited to metal or plastic.

[0074] The first pressing head 541 is in the shape of a plate or block. The shape of the first pressing head 541 includes but is not limited to a cube, a cylinder, a prism or a special shape. The material of the first pressing head 541 is but is not limited to metal or plastic.

[0075] See also Figure 10 and Figure 11 , Figure 10 Based on Figure 8 The cross-sectional structure diagram of the pressing fixture module 540 at the D0-D0 line is shown. Figure 11 Based on Figure 10 The enlarged view of the circled portion at A in the cross-sectional view shown is shown. The first pressing head 541 has a first surface 541a and a second surface 541b that are opposite to each other in the first direction X. The first surface 541a has a first pressing surface 541a1. The first pressing surface 541a1 is used to press the device to be pressed.

[0076] The first pressing head 541 is mounted on the fixed seat 543. The first pressing head 541 is movable in the first direction X relative to the fixed seat 543. Exemplarily, the fixed seat 543 is located on the side of the first pressing head 541 that is opposite to the first pressing surface 541a1, that is, the second surface 541b faces the fixed seat 543, and the first surface 541a is opposite to the fixed seat 543. In this way, the fixed seat 543 can be prevented from interfering with the pressing of the first pressing surface 541a1, which is conducive to improving the pressing reliability of the pressing device 500. Of course, the present application is not limited to this. In other examples, the fixed seat 543 can also be located on the periphery of the first pressing head 541. It can be understood that the specific positional relationship between the fixed seat 543 and the first pressing head 541 can be set according to actual needs, and the present application does not impose specific restrictions on this.

[0077] The second pressing head 542 is in the shape of a plate or block. The shape of the second pressing head 542 includes but is not limited to an annular frame, a cube, a cylinder, a prism or a special shape. The material of the second pressing head 542 is but is not limited to metal or plastic.

[0078] The second pressing head 542 has a second pressing surface 542a1. The second pressing surface 542a1 and the first pressing surface 541a1 face the same direction. This facilitates the first pressing surface 541a1 and the second pressing surface 542a1 to cooperate with each other to press the device to be pressed, thereby increasing the area of the device to be pressed.

[0079] The second pressing head 542 is fixed on the fixing seat 543. The fixing method between the second pressing head 542 and the fixing seat 543 includes but is not limited to gluing, welding, clamping or screw connection. Exemplarily, the fixing seat 543 is located on the side of the second pressing head 542 that is opposite to the second pressing surface 542a1. In this way, the fixing seat 543 can be prevented from interfering with the pressing of the second pressing surface 542a1 on the pressing device to be pressed, which is beneficial to improving the pressing reliability of the pressing device 500. Of course, the present application is not limited to this. In other examples, the fixing seat 543 can also be located on the periphery of the second pressing head 542. It can be understood that the specific positional relationship between the fixing seat 543 and the second pressing head 542 can be set according to actual needs, and the present application does not impose specific restrictions on this.

[0080] Please continue reading Figure 10 and Figure 11 The second pressing head 542 is located on the outer periphery of the first pressing head 541. In some examples, the second pressing head 542 is annular and surrounds the first pressing head 541. In this way, the second pressing surface 542a1 of the second pressing head 542 can also be configured to be annular and extend along the circumference of the second pressing head 542. Thus, the second pressing head 542 can be used to press the skirt 1612.

[0081] It is worth noting that when the pressing device 500 is used to press other non-annular structures, or when the skirt 1612 in the heat spreader 161 is not annular around the middle structure 1611, but a section extending circumferentially along the middle structure 1611, the second pressing head 542 may also not be annular.

[0082] Please continue reading Figure 10 and Figure 11 The elastic member 544 is disposed between the first pressing head 541 and the fixing seat 543. Exemplarily, the connection between the elastic member 544 and the first pressing head 541 includes, but is not limited to, welding, gluing, or clamping. Exemplarily, the connection between the elastic member 544 and the fixing seat 543 includes, but is not limited to, welding, gluing, or clamping.

[0083] The elastic member 544 includes, but is not limited to, a spring, a rubber member, or a combination thereof. The number of the elastic member 544 can be multiple. For example, there can be two, three, four, five, or six elastic members 544. Of course, in other embodiments, there can also be one elastic member 544.

[0084] The elastic member 544 applies an elastic force from the second surface 541 b toward the first surface 541 a to the first pressing head 541 , thereby pushing the first pressing head 541 along the first direction X and causing the first pressing head 541 to move away from the fixing base 543 .

[0085] Specifically, when using the pressing device 500 of an embodiment of the present application to reshape the device to be pressed, the device to be pressed can first be placed on the supporting surface of the second pressing head module 540b, with the skirt 1612 suspended in the air. At this point, the corresponding relationship between the device to be pressed and the first pressing head module 540a is as follows: in a plane perpendicular to the first direction X, the vertical projection of the central structure 1611 is located within the first pressing surface 541a1, and the vertical projection of the area of the skirt 1612 adjacent to the central structure 1611 is located within the first pressing surface 541a1. The vertical projection of the remaining area of the skirt 1612 is located within the second pressing surface 542a1.

[0086] Then, the control driving device 530 drives the first pressing head module 540a to move toward the direction of the device to be pressed. Figure 10 and Figure 11 The first pressing surface 541a1 covers the middle structure 1611 and the area of the skirt 1612 close to the middle structure 1611, and the second pressing surface 542a1 covers the remaining area of the skirt 1612. Of course, it is understandable that in other embodiments, the first pressing surface 541a1 covers the middle structure 1611, and the second pressing surface 542a1 covers the skirt 1612.

[0087] As the driving device 530 continuously drives the first pressing head module 540a, the middle structure 1611 is clamped by the first pressing head 541 and the second pressing head module 540b, and the second pressing head 542 continuously presses downward, causing the skirt 1612 to deform toward the middle plate 121b. Since the first pressing head 541 is movable relative to the fixed seat 543, the elastic force between the elastic member 544 and the first pressing head 541 during the continuous downward pressure of the second pressing head 542 can ensure that the first pressing head 541 always applies pressure to the device to be pressed during the pressing and shaping process, thereby controlling the flatness of the middle structure 1611 and preventing the formation of a protrusion P. In addition, the first pressing head 541 can also be ensured to have a tendency to move away from the device to be pressed relative to the second pressing head 542 during the pressing process, thereby preventing the first pressing head 541 from over-pressing the device to be pressed and damaging it.

[0088] Through the above analysis, it can be seen that the pressing device 500 of the embodiment of the present application can realize the simultaneous pressing of the middle structure 1611 and the skirt 1612, which is similar to the above Figure 6 Compared to the embodiment shown, this method helps to at least to some extent avoid the problem of secondary deformation of the device to be pressed during the pressing process (that is, avoids the problem of the protrusion P mentioned above), improves the pressing effect, and enhances product consistency. At the same time, the first pressing head 541 and the second pressing head 542 perform pressing simultaneously, avoiding the problem of low production efficiency caused by segmented pressing, thereby improving production efficiency.

[0089] As described above, during the pressing process, the first pressing head 541 and the second pressing head 542 move relative to each other in the first direction X. Therefore, in order to prevent the fixed seat 543 from interfering with the relative movement of the first pressing head 541 and the second pressing head 542, in some embodiments, the fixed seat 543 has a sliding groove 5431 on the surface facing the first pressing head 541. The first pressing head 541 is movably connected to the sliding groove 5431. The second pressing head 542 is fixed to the area surrounding the sliding groove 5431 on the surface of the fixed seat 543 facing the first pressing head 541. Of course, the present application is not limited to this. In other embodiments, the sliding groove 5431 may not be provided on the fixed seat 543.

[0090] In some embodiments, please refer to Figure 11 The first pressing head 541 includes a rigid connecting portion 5411 and a flexible portion 5412 .

[0091] The rigid connection part 5411 is in a block or plate shape. The material of the rigid connection part 5411 includes but is not limited to metal or plastic.

[0092] The rigid connection portion 5411 is movably fixed to the fixing seat 543. Specifically, the rigid connection portion 5411 is movably mounted on the above-mentioned sliding groove 5431. The elastic member 544 is connected between the rigid connection portion 5411 and the bottom wall of the above-mentioned sliding groove 5431 of the fixing seat 543.

[0093] The flexible portion 5412 is sheet-shaped. The material of the flexible portion 5412 includes, but is not limited to, rubber, silicone, and acrylic soft glue. Among them, the acrylic soft glue resin is a mixture of acrylic resin, calcium powder, transparent filler, etc., and is relatively soft.

[0094] The flexible portion 5412 is fixed to the rigid connection portion 5411. Exemplary methods for fixing the flexible portion 5412 to the rigid connection portion 5411 include, but are not limited to, gluing, clamping, or screwing. In other embodiments, the flexible portion 5412 and the rigid connection portion 5411 may also be integrally formed. The surface of the flexible portion 5412 facing away from the rigid connection portion 5411 is the first surface 541a.

[0095] Therefore, in the first pressing head 541, a rigid connecting part 5411 is used to connect with the elastic member 544. The rigid connecting part 5411 has a large rigidity and is not easy to deform, which is beneficial to improving the reliability of the connection between the first pressing head 541 and the elastic member 544, and is beneficial to the deformation of the elastic member 544; the first surface 541a is set on the flexible part 5412. Due to the material characteristics of the flexible part 5412, when pressing, the first pressing surface 541a1 of the flexible part 5412 contacts with the device to be pressed, which can adapt to the shape of the device to be pressed, increase the contact area between the first pressing head 541 and the device to be pressed, and improve the pressing effect on the device to be pressed.

[0096] It is understandable that the first pressing head 541 may not include the rigid connection portion 5411 , that is, the entire first pressing head 541 is made of a flexible material.

[0097] In some embodiments, please refer to Figure 11 In order to prevent the first pressing head 541 from escaping from the sliding groove 5431 , a supporting boss 5411 a is provided on one end of the outer peripheral surface of the rigid connecting portion 5411 away from the flexible portion 5412 .

[0098] The support boss 5411a may be annular and extend along the circumference of the rigid connection portion 5411. The support boss 5411a may also be a segment extending along the circumference of the rigid connection portion 5411. For example, when the support boss 5411a is a segment extending along the circumference of the rigid connection portion 5411, there may be a plurality of support bosses 5411a, and the plurality of support bosses 5411a are spaced apart and arranged along the circumference of the rigid connection portion 5411.

[0099] The connection between the support boss 5411a and the rigid connection portion 5411 includes, but is not limited to, gluing, welding, clamping or screw connection. In other embodiments, the support boss 5411a and the rigid connection portion 5411 can also be an integrally formed part.

[0100] A bearing boss 5431a is provided at one end of the inner circumferential surface of the chute 5431, adjacent to the second pressing head 542. The bearing boss 5431a may be annular and extend along the circumference of the chute 5431. Alternatively, the bearing boss 5431a may be a segment extending along the circumference of the chute 5431. For example, when the bearing boss 5431a is a segment extending along the circumference of the rigid connection portion 5411, there may be multiple bearing bosses 5431a, each of which is spaced apart and arranged circumferentially around the chute 5431.

[0101] The connection between the bearing boss 5431a and the fixing seat 543 includes, but is not limited to, gluing, welding, clamping or screw connection. In other embodiments, the bearing boss 5431a and the fixing seat 543 can also be an integrally formed part.

[0102] In the first direction X, the supporting boss 5411a is directly opposite to the bearing boss 5431a, and the supporting boss 5411a is located on the side of the bearing boss 5431a facing away from the second pressing head 542. In this way, the first pressing head 541 is prevented from slipping out of the sliding groove 5431 by the mutual cooperation between the supporting boss 5411a and the bearing boss 5431a.

[0103] It can be understood that when the entire first pressing head 541 is made of flexible material, that is, the first pressing head 541 only includes the flexible portion 5412, the supporting boss 5411a is directly provided on the flexible portion 5412 and cooperates with the bearing boss 5431a.

[0104] In some embodiments, a limiting groove 541c is provided on the second surface 541b of the first pressing head 541. Specifically, the limiting groove 541c is provided on the rigid connection portion 5411. The elastic member 544 is provided in the limiting groove 541c. As the elastic member 544 is susceptible to elastic deformation, placing the elastic member 544 in the limiting groove 541c facilitates smooth assembly of the pressing device 500 and prevents the elastic member 544 from breaking free from between the fixing seat 543 and the first pressing head 541 during the assembly and pressing processes due to elastic deformation.

[0105] For example, there may be multiple limiting grooves 541c. There may also be multiple elastic members 544. Each elastic member 544 may correspond to one limiting groove 541c. In this way, the limiting grooves 541c provide partitioned positioning for the elastic members 544, reducing mutual interference between the elastic members 544 when deforming along the first direction X, thereby ensuring a good pressing effect.

[0106] For some examples, see Figure 11 The outer edge of the surface of the second pressing head 542 having the second pressing surface 542a1 is recessed to form an avoidance step 542b. Therefore, during pressing, the avoidance step 542b can avoid the protruding structure on the middle frame 121 corresponding to the avoidance step 542b, thereby preventing the pressing device 500 from damaging the middle frame 121 and improving the pressing accuracy.

[0107] In some embodiments, in order to facilitate relative movement between the first pressing head 541 and the second pressing head 542 , a gap c is defined between the first pressing head 541 and the second pressing head 542 .

[0108] On this basis, in order to prevent the problem of a bulge in the device to be pressed corresponding to the gap c during the pressing process caused by setting the gap c too large, the size of the gap c is less than or equal to 0.5 mm. Exemplarily, the size of the gap c is less than or equal to 0.3 mm. In another exemplary embodiment, the size of the gap c is less than or equal to 0.1 mm. For example, the size of the gap c is 0.1 mm.

[0109] In other embodiments, there may be no gap c between the first pressing head 541 and the second pressing head 542, that is, the distance between the first pressing head 541 and the second pressing head 542 is 0. Of course, the present application is not limited to this. In other embodiments, the first pressing head 541 and the second pressing head 542 may also abut, that is, there is an over-win state between them. This is sufficient as long as the first pressing head 541 and the second pressing head 542 can move relative to each other.

[0110] Based on any of the above embodiments, in some embodiments, the first pressing head 541 has an extreme position relative to the second pressing head 542. In the extreme position, the first pressing surface 541a1 is located on the side of the second pressing surface 542a1 that is opposite to the second surface 541b. In other words, the first pressing surface 541a1 protrudes from the second pressing surface 542a1.

[0111] It is worth noting that "in the extreme position, the first pressing surface 541a1 is located on the side of the second pressing surface 542a1 facing away from the second surface 541b" means that when the pressing device 500 is not pressed against the pressing device, the first pressing surface 541a1 is located on the side of the second pressing surface 542a1 facing away from the second surface 541b.

[0112] In this way, during the pressing and shaping process, the first pressing surface 541a1 can contact the equipment to be pressed before the second pressing surface 542a1, and press and position the middle structure 1611 and the skirt 1612 adjacent to the middle structure 1611, ensuring that when the second pressing head 542 presses the skirt 1612, it will not cause secondary deformation of the rest of the heat spreader 161.

[0113] In some embodiments, the second pressing head 542 is a rigid component. Specifically, during the pressing and shaping process, the second pressing head 542 needs to bend the skirt 1612, which is a metal component with relatively high rigidity. Therefore, to improve the reliability of the second pressing head 542 pressing the skirt 1612, the second pressing head 542 is a rigid component.

[0114] Specifically, the elastic modulus of the second pressing head 542 may be greater than or equal to 100 GPa, which is helpful to ensure the reliability of the second pressing head 542 in pressing the device to be pressed.

[0115] For example, the elastic modulus of the second pressing head 542 may be 150 GPa, 200 GPa, 250 GPa, 300 GPa, 350 GPa, or 400 GPa.

[0116] Of course, the present application is not limited thereto. In other embodiments, the second pressure head 542 may also be flexible, or formed by a combination of rigid material and flexible material.

[0117] It can be understood that the above description is based on the example that the driving device 530 is connected to the first pressure head module 540a, and drives the first pressure head module 540a to move along the first direction X, so that the first pressure head module 540a and the second pressure head module 540b produce relative movement along the first direction X.

[0118] In other embodiments, see Figure 12 , Figure 12 Schematic diagram of the structure of a laminating device 500 provided in another embodiment of the present application. This embodiment differs from the above embodiment in that two drive devices 530 may be provided. One drive device 530 is connected to a fixed base 543 to drive the first pressing head module 540a to move in the first direction X. The other drive device 530 is connected to the second pressing head module 540b to drive the second pressing head module 540b to move in the first direction X.

[0119] Of course, the present application is not limited to this. In other embodiments, the driving device 530 may also be connected only to the second pressure head module 540b, and drive the second pressure head module 540b to move along the first direction X, so that the first pressure head module 540a and the second pressure head module 540b produce relative movement along the first direction X.

[0120] Exemplarily, the driving device 530 includes but is not limited to a cylinder and a driving motor.

[0121] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0122] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
