TECHNICAL FIELD
[0001] The present disclosure relates to the technical field of terminal equipment, in particular to a bonding jig and a supporting seat thereof, and a terminal bonding method. BACKGROUND
[0002] In the terminal product of the related art, the commonly used screen bonding mode is generally three modes of point gluing bonding, point gluing + cold pressing double-sided adhesive bonding, and cold pressing double-sided adhesive bonding. With the popularization of terminals such as mobile phones, tablet computers, and notebook computers, people's demand for high screen-to-body ratio of terminals is becoming stronger and stronger, which leads to the compression of the black space of the non-display area of the terminal screen being smaller and smaller. The assembly of the screen and the shell of the ordinary terminal can only be bonded by point gluing. However, after the screen and the shell are point glued, the bonding force is extremely strong, and when the terminal has problems such as display area failure and mainboard failure, the screen is extremely difficult to disassemble and has a high scrap rate, which causes a large amount of maintenance cost and material waste. In addition, for the screen and shell point gluing bonding, general after-sales outlets usually do not have point gluing machine equipment, and even if the screen is disassembled safely, the on-site assembly of the screen cannot be realized. Therefore, a screen bonding scheme that meets the requirements of high yield disassembly and high efficiency assembly is extremely important.
[0003] When cold pressing double-sided adhesive is used to bond the screen and the shell, first, the cold pressing double-sided adhesive can be assembled with the shell by using a jig, and a cold pressing machine is used to apply pressure to the double-sided adhesive of the shell to activate the adhesion between the shell and the double-sided adhesive. Then, after the screen and the shell are assembled, a cold pressing machine is used to apply a certain downward pressure to the screen to activate the adhesion between the back adhesive and the screen. However, the cold pressing bonding mode has the following disadvantages: in order to achieve sufficient bonding force, it is usually required that the double-sided adhesive bonding width is large and the adhesive activation pressure is large. In the current environment of high terminal screen ratio, reserving a large amount of adhesive area is obviously contrary to the existing design, and the cold pressing activation pressure of the double-sided adhesive is large, and the ordinary screen cannot bear the large activation pressure. With the extreme stacking of the whole machine, the development direction of the product has tended to be more functional and thinner. The CG thickness of the screen is getting thinner and thinner, and the activation of the cold pressing double-sided adhesive requires a higher activation pressure. The normal activation pressure has gradually exceeded the bearing range of the screen, which may cause damage to the screen during the process and is not easy to detect, which brings great risk after being put on the market.

[0029] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:
[0030] The above technical solution utilizes a hot-press head to apply pressure and activate the adhesive (such as double-sided tape), thereby activating its adhesiveness and achieving reliable bonding between the screen and the casing. This avoids the problems associated with disassembly, such as difficulty in disassembly, low disassembly yield, and unsuitability for on-site assembly at various locations, which are common with dispensing adhesives. This helps reduce maintenance costs and avoid material waste. Furthermore, compared to cold-press adhesives, hot-press adhesives can be made narrower to meet the same adhesive strength requirements. This is particularly advantageous for the current demand for increasingly higher screen-to-body ratios and smaller bezels, allowing for improved screen bonding performance with extremely narrow adhesive widths and providing more design possibilities for the device. Simultaneously, the activation pressure required for hot-press adhesives is much lower than that for cold-press adhesives, making it ideal for increasingly thinner screens in ultra-thin stacked environments. This meets the current pressure tolerance range of screens, protecting the screen while achieving effective bonding and largely preventing damage caused by pressing and holding pressure.
[0031] Moreover, since the support assembly is capable of rotating around the X-axis and / or the Y-axis, during the hot-pressing process of the hot-pressing head, the support assembly can be individually rotated around the X-axis, or individually rotated around the Y-axis, or simultaneously rotated around the X-axis and the Y-axis, with respect to the base, when the hot-pressing head is pressed down, so as to adjust the position in the XY plane, and facilitate the adjustment of the support assembly to the position in alignment with the hot-pressing head, for example, to the horizontal position, so as to adjust the shell of the terminal on the support assembly to the position in alignment with the hot-pressing head. That is, under the action of the hot-pressing head, the support assembly is capable of finding and absorbing the inclination of the support assembly with respect to the horizontal plane or the inclination of the hot-pressing head with respect to the horizontal plane caused by the machining tolerance or the assembly error, so as to facilitate the uniform stress and temperature of the entire glue surface of the glue body, and realize the effective activation of the viscosity of the glue body, and ensure the reliability of the bonding of the screen and the shell.

DETAILED DESCRIPTION
[0048] The example embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, unless otherwise indicated, like numbers in the different drawings represent similar or analogous elements. The following description of example embodiments is not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0049] In addition, the terms "first", "second", and the like used in the embodiments of the present disclosure are used to distinguish one element from another element, and do not have sequential or important meanings.
[0050] In the terminal product, the screen and the shell of the terminal can also be bonded by hot pressing, for example, by hot pressing double-sided adhesive. The hot pressing double-sided adhesive bonding method can make the bonding width narrower under the same bonding performance, and the hot pressing activation pressure of the double-sided adhesive is smaller, which is more friendly to the screen bonding. However, the hot pressing bonding has obvious disadvantages. During the hot pressing process, the double-sided adhesive is very sensitive to the hot pressing temperature, hot pressing time and hot pressing pressure. Due to the manufacturing errors of the machine, the processing errors of the shell of the terminal, the processing errors of the jig (support seat 10 as described below), and the assembly errors of various components, the jig for supporting the terminal cannot be completely in a horizontal position. It will appear that one side is high and the other side is low. During the pressing process of the hot pressing head, since it cannot be completely aligned with the hot pressing head, the shell hot pressing double-sided adhesive will have a large force on one end and a small force on the other end. The hot pressing double-sided adhesive is very sensitive to the hot pressing pressure. When the activation pressure of one end is too large, the double-sided adhesive will be over-pressed in a high temperature environment, the thickness of the double-sided adhesive will become very thin, and the adhesive will overflow and climb the wall of the terminal shell or even exceed the shell, affecting the subsequent assembly process or the appearance of the whole machine. When the activation pressure is too small, the double-sided adhesive does not reach the activation condition, and the bonding force between the terminal shell or the screen is insufficient, so the screen is easy to come off.
[0051] In view of this, as shown in Figures 1 to 4 The present disclosure provides a support seat 10 and a bonding jig 1 comprising the support seat 10, which can comprise a machine table (not shown), a support seat 10, a hot pressing head 20 and a Z-direction driving mechanism (not shown), the Z-direction driving mechanism being in transmission connection with the hot pressing head 20 for driving the hot pressing head 20 to be movably installed on the machine table along the Z-direction, for cooperating with the support seat 10 to realize hot pressing bonding of the adhesive 202 (such as double-sided adhesive) on the shell 201 and / or the screen of the terminal.
[0052] As shown in Figure 5 and Figure 6 The support seat 10 provided by the present disclosure comprises a support assembly 12 and a base 11, the base 11 is used for being installed on the machine table of the bonding jig 1, and the support assembly 12 is used for supporting the terminal 2, and the support assembly 12 is configured to be rotatably installed on the base 11 about the X-direction axis and / or the Y-direction axis.
[0053] When hot pressing, first, referring to Figure 2 , the shell 201 of the terminal can be placed on the support assembly 12, and the adhesive 202 (such as double-sided adhesive) can be placed on the shell 201 by using a corresponding tool. Then, as shown in Figure 3 and Figure 4As shown, the hot-pressing head 20 can be moved downward along the Z direction to a preset position and hot-press the adhesive 202 to activate the adhesion between the lower surface of the double-sided adhesive and the shell 201, so as to realize the adhesion between the adhesive 202 and the shell 201. After the hot-pressing process of the adhesive 202 by the hot-pressing head 20 reaches a preset time length, the hot-pressing head 20 can be moved upward along the Z direction to separate from the adhesive 202. Then, the screen (not shown) of the terminal 2 is aligned with the shell 201, and the lower surface of the screen is in contact with the upper surface of the adhesive 202. After that, the hot-pressing head 20 can be moved downward along the Z direction to a preset position and press the screen with a preset pressure to hot-press the adhesive 202 again, so as to activate the adhesion of the upper surface of the adhesive 202 and realize the adhesion between the adhesive 202 and the screen.
[0054] By the above technical solution, the adhesion of the double-sided adhesive can be activated by hot-pressing the adhesive 202 (such as double-sided adhesive) by the hot-pressing head 20, so as to realize the reliable adhesion between the screen and the shell 201, avoid the problems of difficult disassembly, low disassembly yield and unsuitable on-site assembly at each network point due to the use of dispensing for the screen and the shell 201, and be beneficial to reducing the maintenance cost and avoiding the waste of materials. In addition, compared with the cold-pressing double-sided adhesive method, the hot-pressing double-sided adhesive method can be narrower under the same adhesion requirement, and has more advantages for the current demand of higher screen ratio and smaller black border, so as to realize the adhesion performance requirement of the screen under the extremely narrow adhesive width and reserve more possibilities for the design of the terminal 2. At the same time, the activation pressure required by the hot-pressing double-sided adhesive method is much smaller than that of the cold-pressing double-sided adhesive method, which is very friendly to the thinner screen under the extreme stacking environment of the whole machine, can meet the current pressure bearing range of the screen, protect the screen while realizing effective adhesion, and can avoid the damage of the screen caused by pressing and pressure keeping to a great extent, so that the product has more competitive advantages.
[0055] Moreover, since the support assembly 12 is capable of rotating around the X-axis and / or the Y-axis, during the hot-pressing process of the hot-pressing head 20, the support assembly 12 can be individually rotated around the X-axis, or individually rotated around the Y-axis, or simultaneously rotated around the X-axis and the Y-axis, with respect to the base 11, when the hot-pressing head 20 is pressed down, so as to adjust the position in the XY plane, which is equivalent to setting a universal joint structure between the support assembly 12 and the base 11. Based on this, it is beneficial to adjust the position of the support assembly 12 in the XY plane, which can be adjusted to a position aligned with the hot-pressing head 20, for example, to a horizontal position, so as to adjust the shell 201 of the terminal 2 on the support assembly 12 to a position aligned with the hot-pressing head 20. That is, under the action of the hot-pressing head 20, the support assembly 12 can find and absorb the inclination of the support assembly 12 with respect to the horizontal plane or the inclination of the hot-pressing head 20 with respect to the horizontal plane caused by the machining tolerance or assembly error, so as to facilitate the uniform stress and temperature of the entire adhesive surface of the adhesive 202, and avoid the problem of poor activation of the adhesive 202 caused by the machining error of the machine or the hot-pressing head 20, the machining error of the shell 201 of the terminal, the machining error of the support assembly 12, etc. during the activation of the adhesive 202, so as to achieve effective activation of the adhesion of the adhesive 202, and ensure the reliability of the adhesion of the screen and the shell 201.
[0056] It can be understood that in the present disclosure, the hot-pressing adhesion is not limited to the adhesion of the screen and the shell 201 of the terminal 2, and can be applied to any other scene suitable for hot-pressing adhesion. For example, it can include the adhesion of other devices on the terminal 2 and the shell 201, or other objects suitable for hot-pressing adhesion other than the terminal 2.
[0057] It can be understood that the terminal 2 provided by the present disclosure can include but is not limited to a mobile phone, a tablet computer, a notebook computer, etc.
[0058] In addition, the adhesive 202 is not limited to double-sided adhesive tape, but can also be other forms of adhesive 202, such as single-sided adhesive tape, which is not limited in the present disclosure. For the convenience of description, the following will be described by taking the double-sided adhesive tape as an example.
[0059] The present disclosure does not limit the specific structure of the support assembly 12, as long as the automatic alignment of the support assembly 12 during the pressing process of the hot-pressing head 20 can be realized.
[0060] Optionally, as Figure 5 and Figure 6As shown, in one embodiment of the present disclosure, the support assembly 12 comprises a first frame 121 and a support 122 for supporting the terminal 2, the support 122 being rotatably mounted on the first frame 121 about one of the X-axis and the Y-axis, and / or the base 11 comprises a second frame 111, the first frame 121 being rotatably mounted on the second frame 111 about the other of the X-axis and the Y-axis.
[0061] As mentioned above, due to machining errors, assembly errors and machine processing errors of the support seat 10, etc., the support seat 10 can have an angle with the horizontal plane, causing the support 122 to be inclined relative to the horizontal plane. For example, referring to Figures 7 to 10 , the support seat 10 is not completely flat with the horizontal plane, and the left side is lower than the right side or the left side is higher than the right side. When the shell 201 of the terminal is located on the support 122, it is consistent with the state of the support seat 10, and is in a state of left low right high or left high right low. In this case, under the pressing action of the hot pressing head 20, the terminal 2 can rotate about the Y-axis and / or the X-axis, so that the left side and the right side of the support seat 10, i.e. the support 122, are equal in height, thereby adjusting the shell 201 of the terminal to be horizontal.
[0062] Referring to Figure 7 and Figure 11 , in the front view of the bonding jig 1, the support seat 10 has an angle θ with the horizontal plane in the direction of the drawing surface, and the support assembly 12 is left low right high. In this case, under the pressing action of the hot pressing head 20, the terminal 2 can rotate clockwise about the Y-axis together with the support 122, so that the left side and the right side of the support 122 are equal in height, thereby adjusting the shell 201 of the terminal 2 to be horizontal, so that the shell 201 of the terminal 2 can be aligned with the hot pressing head 20, as shown in Figure 12 .
[0063] Similarly, when the support seat 10 has an angle θ with the horizontal plane as shown in Figure 8 , and the support assembly 12 is left high right low. Under the pressing action of the hot pressing head 20, the terminal 2 can rotate counterclockwise about the Y-axis, so that the left side and the right side of the support 122 are equal in height, thereby adjusting the shell 201 of the terminal 2 to be horizontal, so that the shell 201 of the terminal 2 can be aligned with the hot pressing head 20.
[0064] Similarly, when the support seat 10 has an angle θ with the horizontal plane as shown in Figure 9 , in the side view, the support seat 10 has an angle θ with the horizontal plane, and the support assembly 12 is left low right high. Under the pressing action of the hot pressing head 20, the terminal 2 can rotate clockwise about the X-axis, so that the left side and the right side of the support 122 are equal in height, thereby adjusting the shell 201 of the terminal 2 to be horizontal, so that the shell 201 of the terminal 2 can be aligned with the hot pressing head 20.
[0065] Similarly, when support 10 is as follows Figure 10 As shown, when there is an angle θ with the horizontal plane and the support component 12 is higher on the left and lower on the right, under the downward pressure of the hot pressing head 20, the terminal 2 can rotate counterclockwise around the X-axis, so that the left and right sides of the support component 122 are at the same height, thereby adjusting the housing 201 of the terminal 2 to be horizontal, so that the housing 201 of the terminal 2 can be aligned with the hot pressing head 20.
[0066] For the hot pressing head 20, when processing errors or assembly errors cause... Figures 13 to 16 In various states, the support member 122 can be rotated around the Y-axis or X-axis to achieve automatic alignment between the hot pressing head 20 and the support base 10, so that the entire adhesive surface of the double-sided tape is subjected to uniform force and temperature, avoiding poor activation problems caused by uneven force and temperature on the adhesive surface.
[0067] like Figure 13 As shown in the front view, in the diagram, the hot press head 20 is at an angle θ to the horizontal plane, with the left side lower than the right. Under this condition, under the downward pressure of the hot press head 20, the terminal 2 can rotate clockwise around the Y-axis together with the support member 122, so that the left and right sides of the terminal housing 201 are respectively in contact with the hot press head 20, thereby aligning the terminal housing 201 with the hot press head 20.
[0068] Similarly, when the hot press head is 20... Figure 14 As shown, when there is an angle θ with the horizontal plane, with the left side higher than the right side. Under this condition, under the downward pressure of the hot pressing head 20, the terminal 2 can rotate counterclockwise around the Y-axis together with the support member 122, so that the left and right sides of the terminal housing 201 are respectively in contact with the hot pressing head 20, thereby enabling the housing 201 of the terminal 2 to be aligned with the hot pressing head 20.
[0069] Similarly, such as Figure 15 As shown in the side view, when the hot pressing head 20 forms an angle θ with the horizontal plane, the left side is lower than the right. In this case, under the downward pressure of the hot pressing head 20, the terminal 2 can rotate clockwise around the X-axis together with the support member 122, so that the left and right sides of the terminal housing 201 are respectively in contact with the hot pressing head 20, thereby aligning the terminal housing 201 with the hot pressing head 20.
[0070] Similarly, when the hot press head is 20... Figure 16 As shown, when there is an angle θ with the horizontal plane, with the left side higher than the right side. Under this condition, under the downward pressure of the hot pressing head 20, the terminal 2 can rotate counterclockwise around the Y-axis together with the support member 122, so that the left and right sides of the terminal housing 201 are respectively in contact with the hot pressing head 20, thereby enabling the housing 201 of the terminal 2 to be aligned with the hot pressing head 20.
[0071] The present disclosure does not limit the specific structure of the first frame 121 and the second frame 111.

According to similar steps, the assembly of the second pressing member 42 can be realized.
[0080] AsFigure 5 As shown, the first pressing member 41 is provided with a first connecting hole 61, and the first frame 121 can be provided with a corresponding connecting hole, so that the first screw can be arranged in the first connecting hole 61 to detachably mount the first pressing member 41 on the first frame 121.

Such design is conducive to improving the compactness of the structure of the bonding tool 1.
[0083] During the process of hot pressing the activatable adhesive 202 by the hot pressing head 20, the terminal can move on the support member 122, which can affect the activation effect of the adhesive 202. In view of this, optionally, as shown in Figure 5 and Figure 6 As shown in an embodiment of the present disclosure, the support member 122 includes a support member body 1221 and a support portion 1222 provided on the upper surface of the support member body, and the support portion 1222 is provided with a containing cavity 12221 which is adapted to the shape and size of the shell 201 of the terminal.

[0087] In other embodiments of the present disclosure, the support part 122 can only include the support body 1221, and the upper surface of the support body 1221 can be provided with a groove matched with the shape and size of the shell 201 of the terminal. In this way, the groove can also play a reliable limiting role of the shell 201 of the terminal.
[0088] Optionally, as shown in the drawings, Figure 6 In an embodiment of the present disclosure, the base 11 further includes a bottom plate 112 for connecting with the machine table, and the second frame 111 is installed on the bottom plate 112. The bottom plate 112 is provided with at least one elastic pad 50 arranged (such as bonded or screwed) on the bottom plate 112 at a position corresponding to the corner of the first frame 121. In an embodiment, the elastic pad 50 can play a role in balancing the gravity of the support part 122 and the first frame 121 before the hot-pressing pressure head 20 is pressed down, and can play an initial position positioning function.
[0089] Optionally, the number of elastic pads 50 can be four, and the four elastic pads 50 are arranged on the bottom plate 112 at positions corresponding to the four corners of the first frame 121, so as to further improve the role of balancing the gravity of the support part 122 and the first frame 121.
[0090] Optionally, the elastic pad 50 can be a bubble or rubber, and the present disclosure does not limit it.
[0091] Optionally, as shown in the drawings, Figure 6As shown, the second frame 111 is provided with a third connecting hole 63, and a third screw can be arranged on the bottom plate 112 to mount the second frame 111 on the bottom plate 112. The bottom plate 112 is further provided with a fourth connecting hole 64, and a fourth screw can be used to fix the bottom plate 112 to the machine table. Among them, as shown in the figure, Figure 6 As shown, the third connecting hole 63 and the fourth connecting hole 64 can be multiple, and the third screw and the fourth screw can be correspondingly arranged multiple to improve the reliability of mounting the second frame 111 on the bottom plate 112 and the bottom plate 112 on the machine table, and avoid the shaking of the bottom plate 112 and the second frame 111 during the hot pressing process.
[0092] In order to minimize the risk of damage to the terminal, especially the screen of the terminal, during the hot pressing process of the hot pressing head 20. Optionally, as shown in the figure, Figure 17 As shown in an embodiment of the present disclosure, the hot pressing head 20 of the bonding jig 1 can include a head body 21 and a flexible heat-conducting member 22 mounted on the head body 21. The hot pressing head 20 contacts the adhesive 202 or the screen of the terminal through the flexible heat-conducting member 22 to form a soft contact between the hot pressing head 20 and the terminal, thereby reducing the risk of damage to the terminal. Moreover, the arrangement of the flexible heat-conducting member 22 also facilitates uniform transmission of pressure and temperature of the hot pressing head 20 to the adhesive 202, thereby improving the activation effect on the adhesive 202.
[0093] Optionally, the head body 21 can be made of aluminum alloy material, and the flexible heat-conducting member 22 can be made of heat-conducting silica gel. Both can be integrally formed by injection molding process.
[0094] Optionally, as shown in the figure, Figure 17 As shown, the flexible heat-conducting member 22 includes a main body 221 and a connecting column 222 arranged on the main body 221. The connecting column 222 is inserted and matched in the insertion hole on the head body 21. By matching the connecting column 222 with the insertion hole, the reliability of connecting the flexible heat-conducting member 22 and the head body 21 is improved, and the contact area of the flexible heat-conducting member 22 and the head body 21 is increased, which is conducive to transmitting the hot pressing of the head body 21 to the heat-conducting member 22 and improving the hot pressing efficiency on the adhesive 202.
[0095] Among them, the connecting column 222 can be multiple, and part of the multiple connecting columns 222 can be arranged on the edge of the flexible heat-conducting member 22, and part can be arranged on the surface of the flexible heat-conducting member 22 in contact with the head body 21.
[0096] Optionally, the connecting column 222 and the main body 221 can be made of the same material, for example, both can be heat-conducting silica gel. The present disclosure does not limit the specific structure of the hot pressing head 20, and optionally, as shown in the figure, Figure 17As shown in the embodiment of the present disclosure, the heating press head 20 is provided with a mounting hole 211 for mounting the heating pipe, and the pipe wall of the heating pipe is in contact with the hole wall of the mounting hole 211 to conduct heat, which is conducive to improving the heat conduction effect. When heated, the heating pipe can conduct heat to the press head body 21, and then the press head body 21 conducts heat to the flexible heat conduction piece 22.
[0097] Optionally, as shown in Figures 1-4 and Figure 17 , the mounting hole 211 can be a plurality of mounting holes 211, and each mounting hole 211 can extend along the Y direction. The plurality of mounting holes 211 are arranged in the X direction.
[0098] Since the activation temperature of the heat-pressing double-sided adhesive tape is often between 80 degrees and 110 degrees, and the activation time is as long as about 40 seconds, under the radiation of a long-time high-temperature environment, the release paper carried by the double-sided adhesive tape is easily sucked up, thereby driving the double-sided adhesive tape to deviate from the predetermined activation position, resulting in the double-sided adhesive tape being skewed. In view of this, optionally, as shown in Figure 3 and Figure 17 , in an embodiment of the present disclosure, the heating press head 20 is further provided with a heat dissipation hole 23, so as to play a heat dissipation effect through the heat dissipation hole 23, thereby avoiding the above-mentioned problems caused by excessively high temperature.
[0099] Optionally, as shown in Figure 3 and Figure 17 , the heat dissipation hole 23 can be a plurality of heat dissipation holes 23, and the plurality of heat dissipation holes 23 can be located in the middle of the heating press head 20 and penetrate the heating press head 20, so as to play a rapid heat dissipation effect.
[0100] As shown in Figure 3 and Figure 17 , the heat dissipation hole 23 can include a first heat dissipation hole 212 located on the press head body 21 and a second heat dissipation hole 223 located on the flexible heat conduction piece 22. The center line of the first heat dissipation hole 212 can penetrate the press head body 21 along the Z direction, and the center line of the first heat dissipation hole 212 can penetrate the flexible heat conduction piece 22 along the Z direction.
[0101] Figure 18 A schematic view showing that the shell 201 of the terminal 2 and the adhesive body 202 are in a disassembled state.
[0102] In this disclosure, the Z-axis drive mechanism can adopt a suitable structure. Optionally, in one embodiment of this disclosure, the machine base can be equipped with a mounting frame, which may include a connected vertical beam and a horizontal beam. The lower end of the vertical beam is fixed to the machine base. The Z-axis drive mechanism includes a cylinder mounted on the horizontal beam. The lower end of the cylinder's piston rod is connected to the upper end of a connecting rod (such as a lead screw), and the lower end of the lead screw is connected to the mounting beam. The hot pressing head can be arranged on the mounting beam. Thus, the up-and-down movement of the cylinder's piston rod can drive the connecting rod to move up and down, thereby driving the mounting beam to move up and down, and further driving the hot pressing head 20 to move downward, closer to the terminal 2, and complete the pressing action to activate the colloid 202. Alternatively, it can move upward, away from the terminal 2, to complete the return-to-position action after the colloid 202 has been activated. In addition, when the hot press head 20 is pressed down and ready to activate the colloid, different forces can be applied to the hot press head 20 by adjusting the cylinder pressure, such as by adjusting the pressure through the cylinder regulating valve, thereby enabling the application of different values of hot press pressure as needed.
[0103] It is understood that in other embodiments of this disclosure, the Z-axis drive mechanism may include a motor in addition to a cylinder. The hot pressing head 20 can be connected to the piston rod of the cylinder, and the cylinder can be mounted on a movable block. This movable block and a lead screw arranged along the Z-axis on the machine base form a lead screw and nut mechanism. Thus, by rotating the lead screw, the hot pressing head 20 can be controlled to move up and down along the Z-axis. Through the action of the cylinder, the downward pressure can be transmitted from the hot pressing head 20 to the colloid 202, thereby activating the colloid 202. Alternatively, in other embodiments of this disclosure, a hydraulic cylinder or a linear motor can be used to drive the hot pressing head 20 to move in the Z-axis direction.
[0104] like Figure 17 As shown, optionally, the hot press head 20 (such as the head body 21) may be provided with a fifth connecting hole 213, which can be used to connect with the aforementioned mounting beam (which can be achieved by means of fasteners) to realize the installation of the hot press head 20.
[0105] like Figure 19 As shown, according to another aspect of this disclosure, a terminal bonding method is provided, the method comprising the following steps:
[0106] S100: providing a support base 10 and a hot-pressing head 20, wherein the hot-pressing head 20 is used to hot-press the adhesive 202 on the shell 201 and / or the screen of the terminal, the support base 10 comprises a base 11 used to be mounted to a machine table and a support assembly 12 used to support the terminal, and the support assembly 12 is configured to be rotatably mounted on the base 11 around an X-axis and / or a Y-axis. Alternatively, the hot-pressing head 20 can be movably mounted on the machine table along the Z-axis, and the machine table, the support base 10 and the hot-pressing head 20 used in the method can have the same structure as the machine table, the support base 10 and the hot-pressing head 20 mentioned above.
[0107] S200: placing the shell 201 of the terminal on the support assembly 12 and placing the adhesive 202 (such as double-sided adhesive tape) on the shell 201. Wherein, the shell 201 can be placed in the accommodating cavity 12221 of the support part 1222 of the support piece 122 as shown in the figure, and the adhesive 202 can be mounted on the shell 201 of the terminal by using relevant tools. Figure 6
[0108] S300: moving the hot-pressing head 20 downward along the Z-axis to a preset position and hot-pressing the adhesive 202 to activate the adhesion of the lower surface of the adhesive 202, so as to realize the adhesion of the adhesive 202 and the shell. Wherein, the shell 201 is adjusted to be aligned with the hot-pressing head 20 under the pressing action of the hot-pressing head 20. In this step, as known from the above description, the support assembly 12 can be adjusted to the position aligned with the hot-pressing head 20, such as the horizontal position, by rotating around the X-axis and / or the Y-axis, so as to adjust the shell 201 of the terminal 2 on the support assembly 12 to the position aligned with the hot-pressing head 20, thereby facilitating the uniform stress and temperature of the entire adhesive surface of the adhesive 202, avoiding the problem of poor activation of the adhesive 202 caused by the machining error of the machine table or the hot-pressing head 20, the machining error of the shell 201 of the terminal, the machining error of the support assembly 12, etc., so as to realize the effective activation of the adhesion of the adhesive 202 and ensure the reliability of the adhesion of the adhesive 202 and the shell 201.
[0109] In this step, the movement of the hot-pressing head 20 along the Z-axis and the hot-pressing of the adhesive 202 can be realized by using the above-mentioned lead screw and cylinder.
[0110] Through the above method, the adhesion of the surface of the adhesive 202 connected with the shell 201 can be activated, and the lower surface of the adhesive 202 can be firmly adhered to the shell. In step S300, the preset pressure can be set as required, which is not limited in the present disclosure. In addition, the hot-pressing time can be set as required, for example, 40s.
[0111] After the adhesion of the glue body 202 and the shell 201 is realized, the hot-pressing head 20 can be moved upward along the Z direction to separate from the glue body 202, so as to facilitate the next hot-pressing process.
[0112] Optionally, the glue body 202 can be a double-sided adhesive tape, and the surface of the double-sided adhesive tape adhered to the shell 201 is the lower surface. The above method can further include the following steps:
[0113] After the hot-pressing process of the hot-pressing head 20 on the glue body 202 reaches a preset time length, the hot-pressing head 20 is moved upward along the Z direction to separate from the glue body 202;
[0114] The screen of the terminal is aligned with the shell 201, and the lower surface of the screen is in contact with the upper surface of the glue body 202;
[0115] The hot-pressing head 20 is moved downward along the Z direction to a preset position to hot-press the screen and re-press the glue body 202, activate the adhesion of the upper surface of the glue body 202, and realize the adhesion of the glue body 202 and the screen. The screen is adjusted to be aligned with the hot-pressing head 20 under the downward pressing of the hot-pressing head 20. Since the support assembly 12 can rotate around the X and / or Y axis, the screen of the terminal 2 on the support assembly 12 can be adjusted to be aligned with the hot-pressing head 20, for example, to be adjusted to a horizontal position, so as to adjust the screen to be aligned with the hot-pressing head 20, and thus facilitate the uniform force and temperature of the entire adhesive surface of the glue body 202, effectively activate the adhesion of the upper surface of the glue body 202, and ensure the reliability of the adhesion of the glue body 202 and the screen.
[0116] In this way, the double-sided adhesive tape can be activated twice, and the screen can be adhered to the upper surface of the double-sided adhesive tape to realize the reliable adhesion of the screen and the shell.
[0117] The step of activating the glue body 202 twice by the hot-pressing head 20 is similar to the process of the first activation, which will not be described here.
[0118] Since the glue body 202 is sensitive to temperature and pressure, a suitable hot-pressing temperature and hot-pressing pressure can be preset to effectively activate the adhesion of the glue body 202.
[0119] Before the hot-pressing head 20 contacts the glue body 202 or the screen, the temperature of the hot-pressing surface of the hot-pressing head 20 used to contact the glue body 202 or the screen is heated to a preset temperature. Here, the preset temperature can be set according to actual conditions, and the specific value is not limited here.
[0120] Optionally, when the double-sided adhesive needs to be activated, the hot pressing head 20 can be heated by the heating pipe first, and at the same time, the hot pressing head 20 is moved downward along the Z direction by operating the lead screw. When the hot pressing head 20 moves to a certain position, the machine table conducts the pressing force from the hot pressing head 20 to the terminal shell under the action of the air cylinder, so as to realize the application of the activated pressure. After reaching the set hot pressing activation time, the hot pressing head 20 can be moved upward along the Z direction by operating the lead screw until it returns to the initial position, completing the hot pressing activation process of this round.
[0121] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This application is intended to cover any variations, uses or adaptations of the disclosure that are deemed to fall within the general principles of the disclosure and include the general principles of the disclosure and include the general principles of the disclosure.
