[0002] In related technologies, when assembling the mid-frame of a terminal device (such as a mobile phone) with the mid-plate, it is usually necessary to first position and press the two together, and then weld them together to complete the assembly. During the positioning and pressing process, it is usually necessary for personnel to manually place the cover plate on top of the mid-frame before the mid-frame and mid-plate can be pressed together. After pressing, the cover plate also needs to be manually removed. In mass production, the method of manually picking up or putting down the cover plate usually causes low assembly efficiency. Utility Model Content

[0003] Based on the above-mentioned technical problems, this utility model provides a middle frame plate assembly device and an electronic device assembly system to reduce the problem of low efficiency caused by manual operation of the cover plate during the assembly of the middle frame and the middle plate, so as to at least partially solve the above-mentioned technical problems.

[0004] In a first aspect, this utility model provides a middle frame plate assembly device, comprising: a base including a positioning platform for positioning the middle plate; a cover plate including a pressure plate and a connector, the pressure plate for pressing the middle frame onto the middle plate, and the connector connected to the pressure plate; a clamping mechanism including a main body and a clamping member, the clamping member being connected to the main body and capable of clamping the connector; a driving mechanism connected to the main body, the driving mechanism being used to drive the pressure plate closer to or away from the positioning platform when the clamping member clamps the connector; and an adsorption mechanism connected to the positioning platform, the adsorption mechanism being used to adsorb the pressure plate when the pressure plate is attached to the middle frame, thereby connecting the middle frame and the middle plate.

[0005] Optionally, the main body includes a receiving cavity, and the clamping member is disposed in the receiving cavity; the clamping mechanism further includes a first limiting rod disposed in the receiving cavity, one end of the first limiting rod being connected to the inner sidewall of the main body, and the other end being connected to the clamping member, and the clamping member being able to slide along the extending direction of the first limiting rod.

[0006] Optionally, the clamping mechanism further includes an elastic element connected to the clamping member, the elastic element being used to provide the clamping member with a force for clamping the connector.

[0007] Optionally, the number of clamping members is two and they are arranged at intervals within the receiving cavity; the number of first limiting rods is multiple, and each clamping member is connected to at least one first limiting rod; and / or, the number of elastic members is multiple, and each clamping member is connected to at least one elastic member.

[0008] Optionally, the elastic element is constructed as a helical spring, which is sleeved on the outer wall of the first limiting rod; there are four first limiting rods, and each clamping member connects two first limiting rods.

[0009] Optionally, the clamping member is provided with a limiting hole, which extends in a direction perpendicular to the first limiting rod; the clamping mechanism further includes a second limiting rod passing through the limiting hole, which is used to limit the clamping member in the extending direction of the first limiting rod.

[0010] Optionally, the connector has a protrusion; the clamping member includes a first wedge surface and a second wedge surface, the first wedge surface being able to conform to the protrusion before the clamping member clamps the connector; the second wedge surface being able to conform to the protrusion when the clamping member clamps the connector.

[0011] Optionally, the number of protrusions is two, and they are located on opposite sides of the connector.

[0012] Optionally, the adsorption mechanism includes an electromagnet located on the side of the positioning platform away from the pressure plate.

[0013] Secondly, this utility model provides an electronic device assembly system, including the mid-frame plate assembly device described in any of the above optional solutions.

[0014] Through the above technical solution, namely the mid-frame plate assembly device provided by this utility model, when pressing and assembling the mid-frame and mid-plate of a terminal device (such as a mobile phone) using this device, the mid-plate can be pre-positioned on the positioning table, and then the mid-frame is also placed on the positioning table and initially positioned with the mid-plate. After the approximate position is adjusted, the clamping member holds the connecting member connected to the pressure plate to drive the pressure plate closer to the mid-frame. When one side of the pressure plate can fit against the mid-frame, the clamping member can be released from the connecting member, and the adsorption mechanism connected to the positioning table is activated. The adsorption mechanism adsorbs the pressure plate as a whole. As the pressure plate is adsorbed, the pressure plate and the adsorption mechanism are located at the mid-frame. The middle plate and middle frame between the auxiliary mechanisms are also squeezed and pressed together. After the middle plate and middle frame are assembled by pressing each other, the adsorption mechanism no longer adsorbs the pressure plate. Then, the clamping component clamps the connecting component again, driving the pressure plate to move away from the middle plate and middle frame. The assembled middle plate and middle frame can then be manually removed. Through the above assembly process of the middle plate and middle frame, that is, by clamping the connecting component with the clamping component to drive the pressure plate to move closer to and away from the middle frame, the manual handling of the cover plate is replaced. This simplifies the assembly process of the middle frame and middle plate, improves the automation level of the middle frame and middle plate of the terminal equipment in the assembly process, and thus greatly improves the assembly efficiency.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In related technologies, when assembling the mid-frame of a terminal device (such as a mobile phone) with the mid-plate, it is usually necessary to first position and press the two together, and then weld them together to complete the assembly. During the positioning and pressing process, it is usually necessary for personnel to manually place the cover plate on top of the mid-frame before the mid-frame and mid-plate can be pressed together. After pressing, the cover plate also needs to be manually removed before the assembled mid-frame and mid-plate can be taken away. In mass production, the method of manually picking up or putting down the cover plate usually causes the problem of low assembly efficiency of the mid-frame and mid-plate.

[0020] In view of the above-mentioned technical problems, the first aspect of this utility model provides a middle frame plate assembly device, with reference to... Figures 1 to 5 As shown, the middle frame plate assembly device includes a base 1, a cover plate 2, a clamping mechanism 3, a driving mechanism 4, and an adsorption mechanism 5. The base 1 includes a positioning platform 110 for positioning the middle plate 6. The cover plate 2 includes a pressure plate 210 and a connector 220. The pressure plate 210 is used to press the middle frame 7 onto the middle plate 6, and the connector 220 is connected to the pressure plate 210. The clamping mechanism 3 includes a main body 320 and a clamping member 310. The clamping member 310 is connected to the main body 320 and can clamp onto the connector 220. The driving mechanism 4 is connected to the main body 320 and is used to drive the pressure plate 210 closer to or further away from the positioning platform 110 when the clamping member 310 is clamped onto the connector 220. The adsorption mechanism 5 is connected to the positioning platform 110 and is used to adsorb the pressure plate 210 when it is attached to the middle frame 7, so as to connect the middle frame 7 and the middle plate 6.

[0021] Through the above technical solution, namely the middle frame plate assembly device provided by this utility model, when pressing and assembling the middle frame 7 and the middle plate 6 of a terminal device (such as a mobile phone) using this device, the middle plate 6 can be pre-positioned on the positioning table 110, and then the middle frame 7 is also placed on the positioning table 110 and initially positioned with the middle plate 6. After the approximate position is adjusted, the clamping member 310 clamps the connecting member 220 connected to the pressure plate 210 to drive the pressure plate 210 closer to the middle frame 7. When one side of the pressure plate 210 can fit against the middle frame 7, the clamping member 310 can be released from the connecting member 220, and the adsorption mechanism 5 connected to the positioning table 110 is activated. The adsorption mechanism 5 adsorbs the pressure plate 210 as a whole. As the pressure plate 210 is adsorbed, the middle plate 210 is located on the middle frame 7. The middle plate 6 and the middle frame 7 between the adsorption mechanism 5 and the middle plate 6 are also squeezed and pressed together. After the middle plate 6 and the middle frame 7 are assembled by pressing each other, the adsorption mechanism 5 no longer adsorbs the pressure plate 210. Then, the clamping member 310 clamps the connecting member 220 again, and drives the pressure plate 210 to move away from the middle plate 6 and the middle frame 7. The assembled middle plate 6 and the middle frame 7 can then be manually removed. The above assembly process of the middle plate 6 and the middle frame 7, that is, by clamping the connecting member 220 with the clamping member 310 to drive the pressure plate 210 to move closer to the middle frame 7 and away from the middle frame 7, replaces the manual handling of the cover plate 2. This simplifies the assembly process of the middle frame 7 and the middle plate 6, improves the automation level of the middle frame 7 and the middle plate 6 in the assembly process of the terminal equipment, and thus greatly improves the assembly efficiency.

[0022] It should be noted that, as can be clearly understood in the above embodiments, the middle frame plate assembly device provided by this utility model drives the clamping mechanism 3 to move through the driving mechanism 4, and further clamps the connecting member 220 in the cover plate 2 through the clamping member 310 in the clamping mechanism 3, so as to finally drive the pressure plate 210 to move closer to or away from the middle frame 7, thereby realizing the above-mentioned pressing and assembly operation of the middle frame 7 and the middle plate 6. That is, mechanical automation replaces manual operation. In addition, the driving mechanism 4 mentioned in the above embodiments can also be any suitable mechanism that can drive the clamping mechanism 3 and the cover plate 2 closer to or away from the middle frame 7, and the driving method adopted can also be selected according to the actual situation (e.g., different accuracy of the moving distance), such as hydraulic drive, pneumatic drive, electric drive or mechanical drive, etc. The specific mechanism can be any suitable mechanism such as hydraulic cylinder, pneumatic cylinder, electric cylinder or mechanical telescopic rod, etc. This embodiment does not make specific limitations on this.

[0023] Furthermore, in the above embodiments, the clamping member 310 in the clamping mechanism 3 and the connecting member 220 on the cover plate 2 can be any suitable mechanism and can be any suitable matching method. For example, the clamping member 310 can be any suitable clamping fixture with clamping function, such as a chuck, spring collet, suction cup, gripper, bench vise, etc., and the connecting member 220 can be any clampable part, such as a boss, rod or shaft. The specific structure of the clamping member 310 and the connecting member 220 will be described in detail below, and will not be limited in too much here.

[0024] Furthermore, the adsorption mechanism 5 mentioned in the above embodiments can be any mechanism capable of adsorbing the pressure plate 210 to press the middle frame 7 and the middle plate 6 together. For example, the adsorption mechanism 5 can adopt a suitable structure such as an electromagnet or a vacuum suction cup. In order to ensure that the connection between the middle frame 7 and the middle plate 6 is more stable under the joint pressing of the adsorption mechanism 5 and the pressure plate 210, the adsorption mechanism 5 can be located on the side of the positioning platform 110 away from the pressure plate 210. That is, during the operation of the adsorption mechanism 5, the pressure plate 210 can be adsorbed and brought closer to the adsorption mechanism 5, thereby pressing and fixing the middle plate 6 and the middle frame 7 together. Specifically, the specific structure of the adsorption mechanism 5 will be described in detail below, and will not be limited in too much here.

[0025] The terminal device mentioned in the above embodiments can be any type of terminal device including the middle plate 6 and the middle frame 7, such as a mobile phone or a tablet computer.

[0026] In some implementations, reference Figures 1 to 5 As shown, the main body 320 includes a receiving cavity 321, and the clamping member 310 is disposed in the receiving cavity 321; the clamping mechanism 3 also includes a first limiting rod 330 disposed in the receiving cavity 321. The first limiting rod 330 is disposed in the receiving cavity 321, one end of the first limiting rod 330 is connected to the inner side wall of the main body 320, and the other end is connected to the clamping member 310. The clamping member 310 can slide along the extension direction of the first limiting rod 330.

[0027] Through the above technical solution, both the clamping member 310 and the first limiting rod 330 can be disposed within the receiving cavity 321 of the main body 320, wherein the main body 320 can be... Figure 3 The shell structure shown, namely the main body 320 with the shell structure, can protect the clamping member 310 and the first limiting rod 330 located in the receiving cavity 321. When the clamping mechanism 3 is affected by external factors, such as an impact, the main body 320 can withstand the external impact, thereby preventing the impact from affecting the normal operation of the clamping member 310 and the first limiting rod 330 in the receiving cavity 321. Figure 3As can be clearly seen in the example, the first limiting rod 330 can also play a sliding limiting role on the clamping member 310, that is, the clamping member 310 can move along the extension direction of the first limiting rod 330, thereby realizing the operation of the clamping member 310 approaching and clamping the connector 220 or moving away from the connector 220.

[0028] It should be noted that the number of clamping members 310 mentioned in the above embodiments can be multiple, and the number of first limiting rods 330 can also be single or multiple. When the number of first limiting rods 330 is single, two clamping members 310 can be arranged at intervals in the number of first limiting rods 330. By the mutual approach or distance of the two clamping members 310, the clamping members 310 can clamp the connector 220 or move away from the connector 220.

[0029] Alternatively, when there are multiple first limiting rods 330, there can also be multiple clamping members 310, which correspond one-to-one with the number of first limiting rods 330. By limiting the multiple first limiting rods 330, the multiple clamping members 310 can also move closer to each other or further away from each other to clamp the connector 220 or move away from the connector 220. Specifically, the present invention will elaborate on the number and layout of the first limiting rods 330 and clamping members 310 in detail below, without further limitation.

[0030] In some implementations, reference Figures 1 to 4 As shown, the clamping mechanism 3 also includes an elastic member 340 connected to the clamping member 310, the elastic member 340 being used to provide the clamping member 310 with a force for clamping the connector 220.

[0031] In the above manner, when the clamping member 310 is clamped to the connecting member 220 so as to drive the pressure plate 210 closer to or away from the middle frame 7, the elastic member 340 can use its own elastic force to push the clamping member 310 to press against the connecting member 220, thereby improving the stability of the clamping member 310 clamping the connecting member 220. Furthermore, the elastic member 340 can be any component with elastic function, such as a helical spring or a torsion bar spring. The specific structure of the elastic member 340 will be described in detail below.

[0032] In some implementations, reference Figures 1 to 4 As shown, there are two clamping members 310 arranged at intervals in the receiving cavity 321, and there are multiple first limiting rods 330, with each clamping member 310 connected to at least one first limiting rod 330; and / or, there are multiple elastic members 340, with each clamping member 310 connected to at least one elastic member 340.

[0033] In the above manner, by moving the two clamping members 310 closer to or further away from each other, the clamping members 310 can clamp the connecting member 220 and drive the pressure plate 210 closer to or further away from the middle frame 7. Each clamping member 310 can be connected to at least one first limiting rod 330, which ensures that both clamping members 310 can slide along the extension direction of their respective first limiting rods 330, thereby improving the stability of the clamping members 310 during the sliding process. Furthermore, each clamping member 310 is connected to at least one elastic member 34. When multiple clamping members 310 are simultaneously clamped on the connector 220, multiple elastic members 340 can also simultaneously push the multiple clamping members 310 with elastic force, thereby enabling the clamping members 310 to stably clamp the connector 220, so as to drive the pressure plate 210 closer to or away from the middle frame 7, so as to facilitate the assembly of the middle frame 7 and the middle plate 6. In addition, each clamping member 310 can also be connected to multiple elastic members 340 at the same time. Under the elastic force of multiple elastic members 340, the clamping member 310 can be clamped on the connector 220 more stably.

[0034] In one implementation, reference Figures 1 to 4 As shown, the elastic element 340 is constructed as a helical spring, which is sleeved on the outer side wall of the first limiting rod 330; there are four first limiting rods 330, and each clamping element 310 connects two first limiting rods 330.

[0035] Through the above scheme, four first limiting rods 330 are paired with four helical springs in a one-to-one manner, and every two first limiting rods 330 are connected to a clamping member 310. Thus, when the clamping member 310 slides relative to the extending direction of the first limiting rods 330, the common limiting effect of the two first limiting rods 330 prevents the clamping member 310 from rotating along the length direction of the first limiting rods 330. This ensures that the clamping member 310 only moves axially along the first limiting rods 330, and... Figure 3 and Figure 4 As shown, when each of the two clamping members 310 is limited by the two first limiting rods 330, and the four first limiting rods 330 are parallel to each other in the horizontal direction, the two clamping members 310 can more stably approach or move away from each other at the same height, and thus can more stably clamp the connecting member 220.

[0036] Furthermore, combined Figure 3 and Figure 4 As shown, the two ends of the helical spring can respectively adhere to the inner wall of the main body 320 and the clamping member 310. Under the elastic force of the helical spring, the clamping member 310 can be pushed to move away from the inner wall of the main body 320 so as to clamp the connector 220 through the clamping member 310.

[0037] In some implementations, reference Figures 1 to 4 As shown, the clamping member 310 is provided with a limiting hole 301, which extends in a direction perpendicular to the first limiting rod 330; the clamping mechanism 3 also includes a second limiting rod 350 passing through the limiting hole 301, which is used to limit the clamping member 310 in the extending direction of the first limiting rod 330.

[0038] Through the above method, by the mutual cooperation of the limiting hole 301 and the second limiting rod 350, the movement stroke of the clamping member 310 can be limited, that is, it can be combined with Figure 3 and Figure 4 As shown, the limiting hole 301 can be a strip-shaped hole that allows the second limiting rod 350 a certain amount of movement. The two second limiting rods 350 pass through the limiting holes 301 on the two clamping members 310 respectively. Under the elastic force of the helical spring, the distance between the two clamping members 310 is minimized. When the two clamping members 310 need to clamp the connecting member 220, they can be moved away from each other and compressed. Figure 3 The four helical springs shown can be manually moved or controlled by a CNC machine tool to move the two clamping parts 310 away from each other. The second limiting rod 350 will also move relative to the limiting hole 301. When the distance between the two clamping parts 310 reaches the maximum value, the second limiting rod 350 will also move to the other end of the limiting hole 301. At this time, the space generated between the two clamping parts 310 can be used for the connector 220 to be inserted. Under the elastic force of the helical springs, the two clamping parts 310 are driven to move closer to each other, thereby stably clamping the connector 220.

[0039] The cooperation between the second limiting rod 350 and the limiting hole 301 can reduce or prevent the two clamping parts 310 from being too close to each other under the elastic force of the coil spring, thus preventing them from opening and closing properly. Furthermore, due to the relatively compact internal space of the clamping mechanism 3, one end of the first limiting rod 330 is connected to the inner wall of the main body 320, while the other end is suspended (e.g., ...). Figure 3 As shown, the second limiting rod 350 and the limiting hole 301 can also prevent the clamping member 310 from disengaging from the first limiting rod 330.

[0040] It should be further explained that the movement of the two clamping members 310 toward each other or away from each other, as mentioned in the above embodiments, can be achieved in any suitable way. For example, it can be manually operated by a worker, or to further improve the automation level of the middle frame plate assembly device, it can also be achieved by CNC machine tool control, such as using an automatic control method such as a solenoid valve to move the two clamping members 310 toward each other or away. As long as any reasonable control method can be conceived by those skilled in the art, this embodiment will not elaborate on it in detail.

[0041] In some implementations, reference Figures 1 to 4 As shown, the connector 220 is provided with a protrusion 221; the clamping member 310 includes a first wedge surface 311 and a second wedge surface 312. The first wedge surface 311 can fit against the protrusion 221 before the clamping member 310 clamps the connector 220; the second wedge surface 312 can fit against the protrusion 221 when the clamping member 310 clamps the connector 220.

[0042] In the above manner, the clamping member 310 can more easily clamp the connector 220 using the first wedge surface 311 and the second wedge surface 312 of the clamping member 310. (Refer to...) Figure 3 and Figure 4 As shown, when the clamping member 310 is not clamping the connecting member 220, the clamping member 310 is located above the connecting member 220 and does not contact the connecting member 220. As the clamping member 310 moves down with the driving mechanism 4 and gradually approaches the connecting member 220, the first wedge surface 311 of the clamping member 310 will adhere to the upper part of the protrusion 221 of the connecting member 220. As the clamping member 310 moves down, the protrusion 221 will gradually squeeze the two first wedge surfaces 311 of the two clamping members 310 and push the two clamping members 310 to move away from each other. After the two clamping members 310 are pushed to the farthest distance from each other, the protrusion 221 is also located at the outermost edge of the first wedge surface 311. As the clamping member 310 continues to descend, the lower part of the protrusion 221 will gradually adhere to the second wedge surface 312 of the clamping member 310, as shown. Figure 4 As shown, the inclination direction of the second wedge surface 312 is different from that of the first wedge surface 311. During the continuous downward movement of the clamping member 310, the relative position of the protrusion 221 and the second wedge surface 312 will also change under the thrust of the helical spring. The two clamping members 310 will gradually approach each other during the continuous downward movement. After the clamping member 310 moves into place, the relative position of the two clamping members 310 can be locked by external control devices such as solenoid valves. At this time, the protrusion 221 is clamped by the two second wedge surfaces 312 on the two clamping members 310 respectively, so that the connecting member 220 can be stably clamped by the two clamping members 310, so as to drive the pressure plate 210 connected to the connecting member 220 to move closer to or away from the middle frame 7.

[0043] Furthermore, when it is necessary to release the clamping member 310 from the connecting member 220, the reverse steps of the above embodiment can be adopted, that is, the relative position of the two clamping members 310 can be unlocked by using an external control device such as a solenoid valve, and the two clamping members 310 can be directly pulled upward to disengage the clamping member 310 from the connecting member 220. Specifically, refer to Figure 4As shown, during the upward movement of the clamping member 310, the relative position of the protrusion 221 and the second wedge surface 312 changes. The two clamping members 310 gradually move away from each other and compress the four helical springs respectively. As the clamping member 310 continues to move, the second wedge surface 312 gradually stops adhering to the protrusion 221, and instead, the first wedge surface 311 adheres to the protrusion 221. The inclination direction of the first wedge surface 311 is different from that of the second wedge surface 312. As the clamping member 310 continues to move upward and the first wedge surface 311 adheres to the protrusion 221, and under the elastic force of the helical springs, the two clamping members 310 will approach each other. Finally, after the two clamping members 310 continue to move upward, the clamping member 310 and the connecting member 220 are disengaged to achieve separation.

[0044] As can be understood from the above, the addition of a first wedge surface 311 and a second wedge surface 312 to the clamping member 310 can improve the smoothness of the clamping member 310 in clamping or disengaging from the connector 220, and the connector 220 can be as follows: Figure 2 and Figure 4 The block structure shown can be easily clamped and separated from the clamping member 310 and the connecting member 220 by providing a protrusion 221 on the top edge of the block structure.

[0045] Specifically, the number and arrangement of the protrusions 221 can be arbitrarily suitable, for example in... Figures 1 to 5 In the example, there are two protrusions 221, and the two protrusions 221 are located on opposite sides of the connector 220.

[0046] With the above-described layout, namely the one-to-one correspondence between the protrusions 221 and the clamping members 310, as the two clamping members 310 approach each other, the first wedge surface 311 and the second wedge surface 312 can be in one-to-one contact with the protrusions 221, thereby improving the stability of the two clamping members 310 in clamping the connector 220. Figure 4 As shown, the two clamping members 310 are located on both sides of the connector 220, and both sides of the connector 220 are provided with protrusions 221. When the two clamping members 310 clamp the connector 220, the two clamping members 310 can be located diagonally below the two protrusions 221 respectively. After the relative position of the two clamping members 310 is locked by an external control device such as a solenoid valve, the connector 220 can also be stably clamped, so as to prevent the connector 220 from detaching from the clamping members 310.

[0047] In some implementations, reference Figures 1 to 5 As shown, the adsorption mechanism 5 includes an electromagnet, which is located on the side of the positioning platform 110 away from the pressure plate 210.

[0048] The above technical solution, namely, using an electromagnet to attract the pressure plate 210, allows for a more convenient and faster pressing operation between the middle frame 7 and the middle plate 6. When the pressure plate 210 of the cover plate 2 is attached to the middle frame 7, the electromagnet can be activated to attract the pressure plate 210 as a whole. This allows the middle frame 7 and the middle plate 6, which are located between the positioning table 110 and the pressure plate 210, to be squeezed and quickly pressed together. After the middle frame 7 and the middle plate 6 are assembled, the electromagnet can be de-energized, and then the clamping member 310 can hold the connecting member 220 connected to the pressure plate 210, thereby moving the cover plate 2 upward and completing the assembly process of the middle frame 7 and the middle plate 6.

[0049] Furthermore, in order to enable the pressure plate 210 and the electromagnet to work together better, the pressure plate 210 can be made of any material that can be attracted by the electromagnet, such as iron, copper, aluminum, etc.

[0050] This utility model exemplarily describes the specific working process of the middle frame plate assembly device, which may include the following steps, for example.

[0051] The middle plate 6 is pre-positioned on the positioning stage 110, and then the middle frame 7 is placed above the middle plate 6 for initial positioning. The connecting piece 220 is clamped by the clamping member 310, and the pressure plate 210 is driven by the drive mechanism 4 to move closer to the middle frame 7. After the pressure plate 210 is in contact with the upper surface of the middle frame 7, the relative position of the two clamping members 310 is unlocked by an external control device (such as a solenoid valve). The drive mechanism 4 moves the clamping members 310 upward. After the second wedge surface 312 and the first wedge surface 311 contact the protrusion 221 in sequence, the two clamping members 310 are released from the connecting piece 220. The adsorption mechanism 5 is then activated to adsorb the pressure plate 210 as a whole, thereby pressing the middle frame 7 and the middle plate 6 together. After the middle frame 7 and the middle plate 6 are pressed together, the drive mechanism 4 drives the clamping member 310 to move down again. The first wedge surface 311 and the second wedge surface 312 of the clamping member 310 contact the protrusion 221 of the connector 220 in sequence. When the two clamping members 310 can clamp the connector 220, the relative position of the two clamping members 310 is locked by an external control device (such as a solenoid valve). At this time, the two second wedge surfaces 312 are attached to the protrusion 221 to form a clamping of the connector 220. The drive mechanism 4 drives the clamping mechanism 3 to move up as a whole, which in turn drives the cover plate 2 to move up as a whole. After the cover plate 2 is removed, the personnel can take away the middle frame 7 and the middle plate 6 that are assembled on the positioning table 110, thus completing the assembly of one process.

[0052] In a second aspect, this utility model provides an electronic device assembly system, including the mid-frame and mid-plate assembly device mentioned in the above specific embodiments, and having all the beneficial effects of the above specific embodiments. When using this electronic device assembly system for assembly, the automation level of electronic device assembly can be improved, and the production assembly efficiency can be increased. Furthermore, the mid-frame and mid-plate assembly device is not limited to pressing and assembling only the mid-frame and mid-plate of mobile phones. It can also be used adaptively for assembling the mid-frame and mid-plate of other electronic devices, such as tablet computers.

[0053] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection claimed by the present invention.
