[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0055] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0057] In the above description, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0058] The front shell and the back cover of the electronic device are mostly bonded by adhesive. The viscosity of the adhesive will decrease after being heated, and the higher the temperature of the adhesive, the lower its viscosity. Most existing electronic equipment repair devices are provided with a heating plate made of copper or other materials on a heating platform, and the entire electronic device is placed on the heating plate. The heating plate is used to heat the entire electronic device to soften the adhesive between the front shell and the back cover. However, since the heating plate heats the entire electronic device, the electronic components in the front shell and the back cover are also heated and heated simultaneously. Many electronic components have poor heat resistance. In the process of heating the entire electronic device, the heating plate is very likely to damage the electronic components. Batteries and other components may even explode when heated.

[0059] In order to solve the above problems, there is a method in the industry to protect electronic components by controlling the heating temperature of the heating plate so that the heating temperature is controlled within the heat resistance range of the electronic components. For example, the heating temperature of the heating plate is controlled at 60°C or 70°C, and the maximum cannot exceed 80°C. At this time, although the risk of damage to electronic components can be reduced, the heating temperature is too low, the back glue is not softened enough, and the viscosity is still large. The back cover and the front shell are not easy to disassemble, and the maintenance efficiency is low. When forced disassembly is performed by tools such as picks, it is easy to cause problems such as paint cracking on the back cover and the front shell. The existing methods cannot coordinate the protection of electronic components and the efficiency of back cover disassembly.

[0060] The inventor of this scheme cooperates the ultrasonic vibrator with the front shell fixing device, and the front shell fixing device fixes the front shell of the electronic device, and the ultrasonic vibrator contacts the back cover of the electronic device. The vibration wave generated by the ultrasonic vibrator is transmitted to the back glue between the front shell and the back cover through the back cover, so that the back glue resonates, and then instantly generates high temperature, softens the back glue, and reduces the viscosity. The temperature of the rest of the electronic device will not be affected by the ultrasonic vibrator, and the temperature will not increase significantly, which can avoid the electronic components in the electronic device from being damaged due to excessive temperature. Because the temperature of the rest of the electronic device will not be affected by the ultrasonic vibrator, the ultrasonic vibrator only heats the back glue, which can increase the temperature of the back glue to 100°C or above, fully softens the back glue, and greatly reduces the viscosity. While protecting the electronic components, the back cover is easy to disassemble, which can greatly improve the maintenance efficiency, and can avoid problems such as paint cracking caused by forcibly disassembling the front shell and back cover when the back glue has a large viscosity.

[0061] The electronic equipment repair device provided by the present application is described in detail below in conjunction with specific embodiments.

[0062] Figure 1 A schematic diagram of an embodiment of an electronic equipment repair device is provided. Figure 2 The schematic diagram of the embodiment of the electronic equipment repair device provided is to soften the adhesive. Figure 1 , Figure 2As shown, the electronic equipment maintenance device provided in this embodiment includes: a front shell fixing device 100 and an ultrasonic vibrator 200.

[0063] The ultrasonic vibrator 200 is connected to the front shell fixing device 100 via the first linear motion mechanism 300 .

[0064] The front shell fixing device 100 is used to fix the front shell 820 of the electronic device 800 .

[0065] The first linear motion mechanism 300 is used to drive the ultrasonic vibrator 200 to move closer to or away from the front housing fixing device 100 .

[0066] The ultrasonic vibrator 200 is used to contact the back cover 810 of the electronic device 800 fixed to the front case fixing device 100 .

[0067] It is understandable that the electronic device 800 may be a mobile phone, tablet computer or other device including a front shell 820, a back cover 810 and electronic components, and the electronic components may be various common components such as batteries, circuit boards, sensors, diodes, transistors, etc. In addition, the ultrasonic vibrator 200 and the front shell fixing device 100 may be arranged up and down, left and right, front and back, or in a certain inclined direction, and the ultrasonic vibrator 200 may contact the back cover 810 of the electronic device 800 fixed on the front shell fixing device 100 through the first linear motion mechanism 300.

[0068] When in use, the ultrasonic vibrator 200 is first moved away from the front shell fixing device 100 by the first linear motion mechanism 300, so that the front shell 820 of the electronic device 800 is fixed on the front shell fixing device 100, and the back cover 810 of the electronic device 800 is directed toward the ultrasonic vibrator 200. After the front shell 820 of the electronic device 800 is fixed, the first linear motion mechanism 300 moves the ultrasonic vibrator 200 close to the front shell fixing device 100, and the ultrasonic vibrator 200 is moved toward the front shell fixing device 100, and the ultrasonic vibrator 200 is moved toward the front shell fixing device 100. The ultrasonic vibrator 200 is then activated, and the vibration wave is transmitted through the back cover 810 to the back glue 830 between the back cover 810 and the front shell 820, causing the back glue 830 to resonate. The resonant back glue 830 can instantly generate high temperature, which can reduce the viscosity of the back glue 830 and make the back glue 830 fully softened. At this time, the temperature of the back glue 830 can rise to 100°C or above. After the back glue 830 is fully softened, the back cover 810 can be easily removed from the front shell 820.

[0069] In the above embodiment, the ultrasonic vibrator 200 only heats up the adhesive 830, and the temperature of the rest of the electronic device 800 will not be affected by the ultrasonic vibrator 200, and the temperature will not rise significantly, which can prevent the electronic components in the electronic device 800 from being damaged due to excessive temperature. At the same time, because the temperature of the rest of the electronic device 800 will not be affected by the ultrasonic vibrator 200, the ultrasonic vibrator 200 does not need to consider the heat resistance of the electronic components when heating the adhesive 830, and can heat up to a temperature that fully softens the adhesive 830. At this time, the viscosity of the adhesive 830 is greatly reduced, and the front shell 820 and the back cover 810 can be easily and conveniently disassembled, with high maintenance efficiency. It can also avoid problems such as paint cracking caused by forcibly disassembling the front shell 820 and the back cover 810 when the adhesive 830 is not fully softened, thereby reducing the defect rate caused by maintenance.

[0070] like Figure 1 As shown, in some possible embodiments, the electronic equipment repairing device further includes a workbench 400 , and the front shell fixing device 100 is installed on the workbench 400 .

[0071] The first linear motion mechanism 300 includes a first frame 310, a first mounting seat 330, a first vertical slide rail 320 and a first linear motor. The lower end of the first frame 310 is fixedly connected to the workbench 400 by a first fastener. The first frame 310 is provided with a first vertical slide rail 320. The first mounting seat 330 is slidably connected to the first frame 310 through the first vertical slide rail 320. The first linear motor is installed on the first frame 310. The output end of the first linear motor is fixedly connected to the first mounting seat 330. The ultrasonic vibrator 200 is installed on the first mounting seat 330. The ultrasonic vibrator 200 is located above the front shell fixing device 100. The first linear motor is used to drive the first mounting seat 330 to reciprocate along the first vertical slide rail 320 to make the ultrasonic vibrator 200 approach or move away from the front shell fixing device 100.

[0072] When fixing the front shell 820, the first linear motor drives the first mounting seat 330 to drive the ultrasonic vibrator 200 to move upward, so as to fix the front shell 820 of the electronic device 800 on the front shell fixing device 100. After the front shell 820 is fixed, the first linear motor drives the first mounting seat 330 to drive the ultrasonic vibrator 200 to move downward, so that the ultrasonic vibrator 200 contacts the rear cover 810 of the electronic device 800 fixed on the front shell fixing device 100. With such a configuration, each component is easy to install and easy to operate. The ultrasonic vibrator 200 contacts the rear cover 810 vertically, which can avoid the influence of the ultrasonic vibrator 200's own gravity on the vibration when it is set horizontally or tilted.

[0073] It can be understood that the first linear motor can be an electric, hydraulic or pneumatic motor, the first fastener can be a common fastener such as a bolt, a rivet, a screw, etc., and the first stand 310 can be made of angle steel, a column, etc.

[0074] like Figure 1 As shown, in some possible embodiments, the electronic equipment repair device further includes a second linear motion mechanism 500, a suction cup 600, a transverse slide rail 700 and a third linear motor 710;

[0075] A transverse slide rail 700 is provided on the workbench 400, and the front shell fixing device 100 is slidably connected to the workbench 400 through the transverse slide rail 700. The third linear motor 710 is installed on the workbench 400, and the output end of the third linear motor 710 is fixedly connected to the front shell fixing device 100. The third linear motor 710 is used to drive the front shell fixing device 100 to reciprocate along the transverse slide rail 700.

[0076] The suction cup 600 is installed on the workbench 400 through the second linear motion mechanism 500. The suction cup 600 is above the front shell fixing device 100. The second linear motion mechanism 500 is used to drive the suction cup 600 to move up and down.

[0077] The transverse slide rail 700 is provided with a first working position and a second working position. The front shell fixing device 100 at the first working position is opposite to the ultrasonic vibrator 200 , and the front shell fixing device 100 at the second working position is opposite to the suction cup 600 .

[0078] The ultrasonic vibrator 200 is used to contact the back cover 810 of the electronic device 800 fixed on the front casing fixing device 100 located at the first working position.

[0079] The suction cup 600 is used to absorb the back cover 810 of the electronic device 800 fixed on the front shell fixing device 100 located at the second working position.

[0080] When in use, first in the first working position, the ultrasonic vibrator 200 is used to fully soften the adhesive 830 between the front shell 820 and the back cover 810. After the adhesive 830 is fully softened, the third linear motor 710 drives the front shell fixing device 100 to move along the transverse slide rail 700 to the second working position, and the back cover 810 on the front shell 820 is sucked up by the suction cup 600, so that the front shell 820 and the back cover 810 are separated.

[0081] With such arrangement, the entire process of separating the front shell 820 and the rear cover 810 is automatically performed without manual operation, thereby improving the efficiency of disassembling the front shell 820 and the rear cover 810 .

[0082] like Figure 1 As shown, in some possible embodiments, the second linear motion mechanism 500 includes a second stand 510 , a second mounting seat 530 , a second vertical slide rail 520 and a second linear motor 540 .

[0083] The lower end of the second stand 510 is fixedly connected to the workbench 400 via a second fastener, a second vertical slide rail 520 is provided on the second stand 510, the second mounting seat 530 is slidably connected to the second stand 510 via the second vertical slide rail 520, a second linear motor 540 is installed on the second stand 510, an output end of the second linear motor 540 is fixedly connected to the second mounting seat 530, the second linear motor 540 is used to drive the second mounting seat 530 to reciprocate along the second vertical slide rail 520, a suction cup 600 is installed on the bottom surface of the second mounting seat 530, and the suction cup 600 is above the front shell fixing device 100.

[0084] It is understandable that the second linear motor 540 can be an electric, hydraulic or pneumatic motor, the second fastener can be a common fastener such as a bolt, a rivet, a screw, etc., and the second stand 510 can be made of angle steel, a column, etc.

[0085] After the adhesive 830 is fully heated and the front shell fixing device 100 is moved to the second working position, the second linear motor 540 drives the second mounting seat 530 to drive the suction cup 600 to move downward, so that the suction cup 600 absorbs the back cover 810 of the electronic device 800 fixed on the front shell fixing device 100, and then the second linear motor 540 drives the second mounting seat 530 to drive the suction cup 600 to move upward, so that the back cover 810 absorbed by the suction cup 600 moves upward, and the front shell 820 and the back cover 810 are disassembled. In this way, each component is easy to install and easy to operate.

[0086] like Figure 1 , Figure 2 As shown, in some possible embodiments, the ultrasonic vibrator 200 includes an ultrasonic transducer 210, a horn 220, and a vibration head 230. The two ends of the horn 220 are respectively connected to the ultrasonic transducer 210 and the vibration head 230, the ultrasonic transducer 210 is connected to the front shell fixing device 100 through the first linear motion mechanism 300, the vibration head 230 is located between the ultrasonic transducer 210 and the front shell fixing device 100, and the vibration head 230 is used to contact the back cover 810 of the electronic device 800 fixed on the front shell fixing device 100.

[0087] With such arrangement, the efficiency of heating the backing glue 830 can be improved through the amplitude transformer 220 , and at the same time, the service life of the ultrasonic transducer 210 can be improved; in addition, the vibration head 230 can be in close contact with the back cover 810 over a large area, which is conducive to transmitting the vibration wave to the backing glue 830 .

[0088] It is understandable that the ultrasonic vibrator 200 may also include a controller, which is used to control parameters such as the amplitude, frequency and vibration duration of the vibration wave generated by the ultrasonic transducer 210, thereby controlling the heating effect on the backing glue 830.

[0089] For example, the ultrasonic transducer 210 is mounted on the first mounting seat 330, the vibration head 230 can be cubic in shape and located below the first mounting seat 330, the lower end of the amplitude transformer 220 is fixedly connected to the center of the top surface of the vibration head 230, the upper end of the amplitude transformer 220 passes through the through hole on the bottom surface of the first mounting seat 330 and is connected to the ultrasonic transducer 210, and the bottom surface of the vibration head 230 is used to contact the back cover 810 of the electronic device 800 fixed on the front shell fixing device 100.

[0090] like Figure 1 As shown, in some examples, the vibration head 230 is provided with a vertically extending strip hole 231 and a transverse groove 232, so that the weight of the vibration head 230 can be reduced, which is beneficial to the transmission of vibration waves.

[0091] like Figure 2 As shown, in some possible embodiments, a back cover receiving groove is provided on the surface of the ultrasonic vibrator 200 for contacting the back cover 810, and a first contact surface 233 is provided on each side wall of the back cover receiving groove. The shape of each first contact surface 233 is a concave arc surface matching the shape of the corresponding side edge on the back cover 810, and each first contact surface 233 is used to fit with the corresponding side edge on the back cover 810.

[0092] It can be understood that the overall shape of the back cover receiving groove corresponds to the shape of the back cover 810 of the electronic device 800. When the back cover 810 of the electronic device 800 is a rectangular cover with a flange, the back cover receiving groove can be cubical. When the back cover 810 of the electronic device 800 is a circular cover with a flange, the back cover receiving groove can be cylindrical.

[0093] When in use, the first contact surfaces 233 on each side are respectively fitted with the corresponding side edges of the back cover 810, and the first contact surfaces 233 on each side drive the back cover 810 to vibrate. This helps the ultrasonic vibrator 200 to transmit the vibration wave to the back cover 810, and then from the back cover 810 to the back glue 830, which can improve the heating efficiency of the back glue 830.

[0094] For example, the rear cover receiving groove can be set on the bottom surface of the cubic vibration head 230, the lower part of the side wall of the rear cover receiving groove is the first contact surface 233, and the upper part of the rear cover receiving groove can reserve space for accommodating various structures on the surface of the rear cover 810.

[0095] Figure 3 A schematic diagram of the upper surface of a front shell fixing device of an embodiment of the electronic equipment repair device provided, Figure 4 In the embodiment of the electronic equipment repairing device provided, a schematic diagram of the wide side of the electronic equipment clamped by the clamping block is provided. Figure 5 In the embodiment of the electronic equipment repair device provided, a schematic diagram of the long side of the electronic equipment clamped by the clamping block is shown. Figure 3-Figure 5 As shown, combined with Figure 1 In some possible embodiments, the front shell fixing device 100 includes a placement table 110 and a clamping block 140. The ultrasonic vibrator 200 is connected to the placement table 110 through a first linear motion mechanism 300. A front shell placement groove 120 is provided on the surface of the placement table 110. The front shell placement groove 120 is a cube with rounded corners. Clamping blocks 140 are installed on the four circumferential sides of the front shell placement groove 120. All the clamping blocks 140 are installed on the side walls of the front shell placement groove 120 through linear cylinders.

[0096] Each linear cylinder is used to drive the corresponding clamping block 140 to move toward the front shell 820 placed in the front shell placement groove 120, so that the multiple clamping blocks 140 clamp the front shell 820.

[0097] With this arrangement, the front shell 820 can be clamped and removed from the storage table 110 conveniently and firmly. When the back glue 830 is heated, the front shell 820 is clamped and remains stationary, which is beneficial to the heating of the back glue 830 and the protection of the electronic components in the front shell 820. In addition, the use of a linear cylinder is more cost-effective.

[0098] Of course, in other embodiments, common fastening structures such as an adsorption structure, a snap structure, and a locking structure may also be provided on the storage table 110 to fix the front shell 820 placed on the storage table 110 .

[0099] It is understandable that the linear cylinder can also be replaced by common linear drive devices such as linear hydraulic motors and linear electric motors.

[0100] In some examples, the placement table 110 is slidably connected to the workbench 400 via a transverse slide rail 700 , and the ultrasonic vibrator 200 is installed on the workbench 400 via a first linear motion mechanism 300 .

[0101] like Figure 3-Figure 5 As shown, in some possible embodiments, the surface of the clamping block 140 used to clamp the front shell 820 is the second contact surface 142, and the shape of the second contact surface 142 of each clamping block 140 is a concave arc surface matching the shape of the corresponding side wall on the front shell 820, and the second contact surface 142 of each clamping block 140 is used to fit with the corresponding side wall on the front shell 820.

[0102] With such a configuration, the clamping block 140 clamps the front shell 820 more firmly, which is beneficial to the heating of the backing glue 830 and the protection of the electronic components in the front shell 820 .

[0103] like Figure 3 , Figure 5As shown, in some possible embodiments, an in-place detection sensor 150 is also provided in the front shell placement groove 120, and the in-place detection sensor 150 is installed on the side wall of the front shell placement groove 120. Two in-place detection sensors 150 are installed on each of the four circumferential sides of the front shell placement groove 120. The clamping block 140 installed on the side wall of the front shell placement groove 120 is located between the two in-place detection sensors 150 installed on the same side wall. All the in-place detection sensors 150 communicate with the linear cylinders. The in-place detection sensors 150 are used to detect the in-place information of the front shell 820 and control the start-up of each linear cylinder.

[0104] It can be understood that the in-place detection sensor 150 can be a common sensor for detecting the position of an object, such as an infrared sensor, an ultrasonic sensor, etc., and the in-place information refers to the information that the front shell 820 is completely placed on the storage table 110.

[0105] With such a configuration, after the in-place detection sensor 150 obtains the information that the front shell 820 is completely placed on the storage table 110, it automatically sends a start signal to each linear cylinder and controls each linear cylinder to start, so that the multiple clamping blocks 140 cooperate with each other to clamp the front shell 820, which is conducive to realizing automatic control and improving work efficiency. Two in-place detection sensors 150 are installed on each of the four circumferential sides of the front shell placement groove 120, and the clamping block 140 installed on the side wall of the front shell placement groove 120 is located between the two in-place detection sensors 150 installed on the same side wall, which can ensure that each side of the front shell 820 is placed on the storage table 110, and then the linear cylinder is controlled to start, avoiding accidents caused by the clamping block 140 clamping the front shell 820 that is not placed in place. At the same time, the clamping block 140 will not block the in-place detection sensor 150, which is conducive to the detection of the front shell 820.

[0106] like Figure 3-Figure 5 As shown, in some possible embodiments, a lifting platform 130 is provided in the front shell placement groove 120, and the lifting platform 130 is arranged in the middle of the groove bottom of the front shell placement groove 120. The lifting platform 130 is used to lift the front shell 820 placed in the front shell placement groove 120, and the length of the lifting platform 130 is smaller than the length of the front shell 820, and the width of the lifting platform 130 is smaller than the width of the front shell 820.

[0107] With such arrangement, after the front shell 820 is lifted, the clamping block 140 can clamp the side of the front shell 820 starting from the bottom side of the front shell 820, avoiding restriction of the bottom side of the front shell placement groove 120 on the movement of the clamping block 140, and clamping the front shell 820 more firmly.

[0108] like Figure 3 , Figure 5As shown, in some possible embodiments, at least one side of the front shell placement slot 120 has a first pick-up notch 121, and the clamping block 140 installed on the side with the first pick-up notch 121 has a second pick-up notch 141, and the second pick-up notch 141 is located on the side of the clamping block 140 facing the middle of the front shell placement slot 120, and the second pick-up notch 141 is arranged opposite to the first pick-up notch 121. Such an arrangement facilitates the operator to take and place the front shell 820.

[0109] In some examples, both long sides of the front shell placement slot 120 are provided with a first pick-up notch 121, and the two first pick-up notches 121 located on the two long sides of the front shell placement slot 120 are arranged opposite to each other, and the clamping blocks 140 installed on the two long sides of the front shell placement slot 120 are provided with a second pick-up notch 141, and the second pick-up notch 141 is located on the side of the clamping block 140 facing the middle of the front shell placement slot 120, and the second pick-up notch 141 is arranged opposite to the first pick-up notch 121, and all the first pick-up notches 121 and the second pick-up notches 141 are arc-shaped. With such a configuration, it is more convenient for operators to take and place the front shell 820.
