Abstract

The embodiment of the present application discloses an assembly device, a driving assembly drives an operating assembly to move through a plug-in part, so that the operating assembly can adjust the positional relationship between a functional part and a circuit board. Thus, on the one hand, the second rotating shaft is arranged above the first rotating shaft, and the first rotating part and the second rotating part can be synchronously rotated by using a lock part and the second rotating shaft, so that the driving pin drives the functional part to rotate along the first rotating shaft, and further makes the functional part of the product avoid the processing area. On the other hand, during the driving process of the driving assembly, the lock part can also avoid the situation that the second rotating part simultaneously swings along the first rotating shaft and the second rotating shaft when the cover part switches the swinging mode. The stability of the operation of the assembly device is improved. In the multiple uses of the assembly device, the lock part can be reset in time, and the operation difficulty of the assembly device is reduced.

[0002] During product assembly, it is essential to ensure the precision requirements between components. Taking 3C electronic devices as an example, their small size and numerous internal components, especially those close together, can cause difficulties for operators during installation. This is particularly true for bonded components, which require ensuring the cleanliness of the bonding areas while maintaining assembly precision during connection. Therefore, simplifying assembly processes and improving efficiency are problems that need to be addressed. Summary of the Invention

The second rotating member and the first rotating member are detachably connected via the other locking portion and rotatably connected via the second rotating shaft. The second rotating member has a drive hole. The second rotating shaft is located above the first rotating shaft and is close to the top of the support portion relative to the first rotating shaft.

[0014] The cover drives the functional component to rotate along the second rotating shaft to the bearing portion. The side of the functional component near the shell corresponds to the processing area. The shell and the functional component are respectively disposed on the bearing portion and the cover. The circuit board of the product is disposed on the shell and electrically connected to the functional component through a connector. The processing area is located on the side of the shell near the first rotating shaft.

[0015] Furthermore, the unlocking pin includes a first unlocking pin and a second unlocking pin, and the driving pin includes a first driving pin and a second driving pin.

[0016] The drive assembly includes a mounting frame and a transmission part. The transmission part includes a first driven swing arm, a second driven swing arm, a driving swing arm, and a connecting rod. The first driven swing arm has a first hinge end and a third hinge end, and the second driven swing arm has a second hinge end and a fourth hinge end. The first hinge end and the second hinge end are hinged to the mounting frame. The two ends of the connecting rod are respectively hinged to the third hinge end and the fourth hinge end. The first driving pin and the second driving pin are respectively disposed on the first driven swing arm and the second driven swing arm. The first unlocking pin and the second unlocking pin are disposed on the mounting frame.

[0017] The active pendulum drives the first and second driven pendulums to swing together via the adapter rod, and the distance from the first hinge end to the first drive pin is less than the distance from the second hinge end to the second drive pin.

[0018] Furthermore, the distance from the first hinge end to the third hinge end is greater than the distance from the second hinge end to the fourth hinge end;

[0019] The active swing arm has a drive groove, and the transmission part further includes a roller, which is disposed on the active swing arm and extends into the drive groove;

[0020] The active swing arm swings toward the support part by a predetermined angle, the roller rolls along the drive groove and drives the adapter rod to approach the support part, and at the same time the swing angle of the first driven swing arm is greater than the swing angle of the second driven swing arm.

[0021] Furthermore, the adapter rod includes opposing long arms and short arms, the long arms and the short arms are perpendicular to each other and connected, the end of the short arm is connected to the third hinge end, and the end of the long arm is connected to the fourth hinge end.

[0022] The roller is equipped with the long arm, the second driven swing arm swings 90 degrees, and the length direction of the short arm is perpendicular to the top surface of the bearing part.

[0023] Furthermore, both the first rotating member and the second rotating member have a locking groove and a guide slope, the two locking parts are respectively disposed in the two locking grooves, and the elastic member pushes the locking pin out of the locking groove;

[0024] The cover rotates away from the bearing portion, the guide slope abuts against the end of the locking pin and pushes the locking pin to the bottom of the locking groove until the locking pin is inserted into the first locking hole, locking the seat body with the first rotating member, or the locking pin is inserted into the second locking hole, locking the seat body with the first rotating member.

[0025] Furthermore, the assembly equipment includes:

[0026] The displacement assembly includes a movable plate, a stationary plate, and a slide rail. The slide rail includes a first slide rail and a second slide rail. The first slide rail is disposed above the second slide rail and perpendicular to each other. The second slide rail is disposed on the stationary plate. The drive assembly is disposed on the movable plate and the movable plate moves horizontally relative to the stationary plate through the slide rail.

[0027] The displacement component is configured to move the drive component between a first stroke and a second stroke, wherein in the first stroke, the first unlocking pin is inserted into the first lock hole, and in the second stroke, the second unlocking pin is inserted into the second lock hole.

[0028] Furthermore, the stationary plate body has a first guide groove, the first guide groove includes a first extension section, a second extension section and a third extension section, the third extension section is connected between the first extension section and the second extension section, and the extension direction of the first extension section and the second extension section is parallel to the axial direction of the drive hole.

[0029] The displacement assembly further includes a first rotary driver, a guide rod, and a drive arm. The drive arm includes a second guide groove. One end of the guide rod is connected to the stationary plate, and the other end passes through the first guide groove and extends into the second guide groove.

[0031] Furthermore, the drive assembly also includes a second rotary driver, the output shaft of which is connected to the active rocker arm;

[0032] The assembly equipment also includes:

[0033] A control circuit is communicatively connected to the first rotary driver and the second rotary driver. The control circuit is configured to alternately output a first drive signal or a second drive signal to the first rotary driver, and output a third drive signal to the second rotary driver, while simultaneously driving the first rotary driver and the second rotary driver to move alternately. The first drive signal and the second drive signal are used to control the first rotary driver to rotate in opposite directions, and the third drive signal is used to control the second rotary driver to swing.

[0034] Furthermore, the second rotating member has a first positioning surface, and the seat has a second positioning surface;

[0035] The length direction of the short arm is perpendicular to the top surface of the bearing part, and the first positioning surface abuts against the second positioning surface.

[0036] In the assembly equipment of this invention, the driving component drives the operating component to move via a plug-in part, allowing the operating component to adjust the positional relationship between the functional component and the circuit board. Thus, on one hand, by positioning the second rotating shaft above the first rotating shaft, a locking part and the second rotating shaft allow the first and second rotating components to rotate synchronously. This facilitates the driving pin driving the functional component to rotate along the first rotating shaft, thereby ensuring the functional component avoids the processing area, facilitating processing by the operator. This improves product assembly speed. On the other hand, during the driving process of the driving component, the locking part also prevents the second rotating component from simultaneously swinging along both the first and second rotating shafts when the cover switches its swing mode. This improves the operational stability of the assembly equipment. Furthermore, the locking part can promptly reset after multiple uses of the assembly equipment, reducing the operational difficulty of the assembly equipment. Attached Figure Description

[0080] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0081] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0082] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0083] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0084] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0085] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or operation besides those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

The assembly equipment in the figure includes an operating platform 6 and an operating component 1, a driving component 2, and a positioning component 4 disposed on the operating platform 6. The positioning component 4 can drive the driving component 2 to change position.

Figure 9 The processing area A11 is shown using cross-sectional lines. Figure 10 The processing area A11 in the diagram is shown with a thick solid line, while... Figure 10 The image also uses dashed lines to illustrate tweezers used to peel off release paper.

[0092] Figure 11 This is a schematic diagram showing the positional relationship between product A and the first rotating shaft 111 and the second rotating shaft 112 in this embodiment. The approximate outline of the second rotating shaft 112 is shown by a dashed line, and the approximate outline of the first rotating shaft 111 is shown by a thick solid line. The functional component A2, shown by the thin solid line, thick solid line, and dashed line, forms angles of 90 degrees, 45 degrees, and 0 degrees with the supporting part 12, respectively. The functional component A2, shown by the thick solid line, rotates along the first rotating shaft 111, while the functional component A2, shown by the dashed line, rotates along the second rotating shaft 112. The figure also shows functional component A2′, which rotates 90 degrees along the first rotating shaft 111.

[0093] In some implementations, such as Figures 1-2 As shown, the assembly equipment in this embodiment includes an operation component 1 and a drive component 2.

[0094] Further reference Figure 3-4 As shown, the drive assembly 2 includes a connector 22. The connector 22 includes a drive pin 22b. The drive assembly 2 is disposed on one side of the operating assembly 1, and drives the operating assembly 1 to move via the unlocking pin 22a and the drive pin 22b.

[0095] Further reference Figures 5-8 As shown, the operating assembly 1 includes a support portion 12, a cover portion 13, and a first rotating portion 11. The first rotating portion 11 includes a first rotating shaft 111, a second rotating shaft 112, a first rotating member 31, a second rotating member 32, a base 113, and two locking portions 33. The cover portion 13 is disposed on the second rotating member 32, and the support portion 12 is fixedly connected to the base 113. The first rotating member 31 is detachably connected to the base 113 via one locking portion 33 and is rotatably connected to the first rotating shaft 111. The second rotating member 32 is detachably connected to the first rotating member 31 via the other locking portion 33 and is rotatably connected to the second rotating shaft 112. The second rotating shaft 112 is located above the first rotating shaft 111 and is close to the top of the support portion 12 relative to the first rotating shaft 111. The elastic member 332 can be a compression spring.

[0096] Further reference Figures 9-10 As shown, in this embodiment, the operating component 1 is used to set product A and drive product A to move via the support part 12 and the cover part 13. The shell part A1 and the functional component A2 of product A are respectively disposed on the support part 12 and the cover part 13. The circuit board A4 of product A is disposed on the shell part A1 and electrically connected to the functional component A2 via the connector A3. The shell part A1 has a processing area A11 on the side near the first rotating shaft 111.

[0097] Specifically, in this embodiment, product A is a mobile phone, and functional component A2 is the mobile phone screen. The aforementioned shell A1 includes a mid-frame. The mid-frame is fixedly connected to the mobile phone screen by adhesive. Connector A3 is a ribbon cable, and the mobile phone screen is connected to the circuit board A4 via the ribbon cable. Adhesive is provided on the inner side of the mid-frame, and release paper is provided on the adhesive to ensure its cleanliness and adhesion. When the mid-frame is placed on the support part 12, the edge of the mid-frame near the first pivot 111 will be adjacent to the ribbon cable. That is, the adhesive inside the edge near the first pivot 111 will be close to the ribbon cable. In order to bond the mobile phone screen to the mid-frame, the release paper inside the edge (i.e., processing area A11) needs to be removed.

[0098] In this embodiment, the locking part 33 is used to lock the first rotating member 31 and the seat 113 and the first rotating shaft 111 and the second rotating member 32 together in an unlockable manner.

[0099] The drive assembly 2 is configured to drive the drive pin 22b to be inserted into the drive hole 321 and to cause the cover 13 to swing toward the support portion 12.

[0100] Simultaneously, the operating component 1 is configured such that when the second rotating member 32 rotates along the first rotating shaft 111, the first rotating member 31 rotates in tandem with the second rotating shaft 112 via the locking part 33 corresponding to the second rotating member 32 (e.g., Figure 6 and Figure 8 (As shown). This is to move functional component A2 away from processing area A11. Furthermore, the edge of cover 13 near the first pivot 111 is offset from processing area A11 (as shown). Figure 10 As shown), the cover 13 pushes the ribbon cable and the phone screen away from the processing area A11. This allows the operator to use tools such as tweezers to reach into the processing area A11 from the side of the cover 13 away from the support part 12, thereby removing the release paper from the adhesive.

[0101] Operating component 1 is further configured such that when the second rotating member 32 rotates along the second rotating shaft 112, the first rotating member 31 is fixedly connected to the base 113 via the locking part 33 corresponding to the first rotating shaft 111 and the base 113 (e.g., Figure 7 and Figure 8As shown), so that functional component A2 is assembled with housing A1. This makes it easier to align the phone screen with the mid-frame.

[0102] Specifically, such as Figure 11 As shown, in this embodiment, the first rotating shaft 111 is closer to the bottom of the bearing portion 12 than the second rotating shaft 112 (e.g., Figure 11 (As shown at the midpoint L5). The second rotating shaft 112 corresponds to the top of the bearing portion 12 and is located axially close to the processing area A11.

[0103] When the cover 13 and the supporting part 12 are at a 90-degree angle, there is a gap between the bottom of the cover 13 and the supporting part 12 (e.g., Figure 1 and Figure 9 (As shown). In this configuration, when functional component A2 rotates along the first pivot 111, the gap between the support portion 12 and the bottom of the cover portion 13 gradually increases, and the ribbon cable also moves simultaneously towards the side of the shell portion A1 away from the processing area A11, exposing the processing area A11 to facilitate the removal of the release paper by the operator. When functional component A2 rotates along the second pivot 112, the position of functional component A2 near the second pivot 112 gradually moves closer to the processing area A11 until the side of functional component A2 near the second pivot 112 is aligned with the processing area A11, so that the adhesive on the inside of the phone screen and the middle frame can be bonded together. Simultaneously, as... Figure 11 As shown, when the side of functional component A2 closest to the second pivot 112 is attached to the processing area A11, the side of functional component A2 furthest from the second pivot 112 can also be attached to the shell portion A1 at the same time. In this configuration, the phone screen and the top surface of the mid-frame are approximately parallel.

[0104] It should be understood that when functional component A2 rotates along the first rotating shaft 111, the locking part 33 provided on the second rotating component 32 can cooperate with the second rotating shaft 112 to prevent relative rotation between the first rotating component 31 and the second rotating component 32. Conversely, when functional component A2 rotates along the second rotating shaft 112, the locking part 33 provided on the first rotating component 31 can also cooperate with the first rotating shaft 111 to prevent rotation between the first rotating component 31 and the base 113. This greatly improves the stability of the movement of the operating component 1.

[0105] In summary, in the assembly equipment of this embodiment, the drive assembly 2 drives the operation assembly 1 to move via the plug-in part 22, so that the operation assembly 1 can adjust the positional relationship between the functional component A2 and the circuit board A4. Thus, on the one hand, by placing the second rotating shaft 112 above the first rotating shaft 111, a locking part 33 and the second rotating shaft 112 can cause the first rotating component 31 and the second rotating component 32 to rotate synchronously, so that the drive pin 22b drives the functional component A2 to rotate along the first rotating shaft 111, thereby causing the functional component A2 of product A to avoid the processing area A11, facilitating processing of the processing area A11 by the operator. This improves the assembly speed of product A. Simultaneously, by using the drive pin 22b in conjunction with the locking part 33, the functional component A2 can also rotate along the second rotating shaft 112, facilitating the assembly of the functional component A2 with the shell part A1, ensuring assembly accuracy. On the other hand, during the driving process of the drive assembly 2, the locking part 33 can also prevent the second rotating component 32 from simultaneously swinging along both the first and second rotating shafts 111 and 112 when the cover part 13 switches its swing mode. This improves the operational stability of the assembly equipment. Furthermore, the lock 33 can reset promptly during repeated use of the assembly equipment, reducing the operational difficulty of the equipment.

[0106] Furthermore, the insertion part 22 also includes an unlocking pin 22a. The base 113 has a first locking hole 1131, and the first rotating member 31 has a second locking hole 311. The locking part 33 includes a locking pin 331 and a resilient member 332. One locking part 33 is disposed on the first rotating member 31, with one end of the locking pin 331 inserted into the first locking hole 1131 and the other end abutting against the resilient member 332. The other locking part 33 is disposed on the second rotating member 32, with one end of the locking pin 331 inserted into the second locking hole 311 and the other end abutting against the resilient member 332.

[0107] The drive assembly 2 is also configured to drive the unlocking pin 22a to push the locking pin 331 out of the first locking hole 1131 or the second locking hole 311 when the drive pin 22b is inserted into the drive hole 321.

[0108] In this embodiment, the locking part 33 of the elastic element 332 can also drive the locking pin 331 to be re-inserted when it corresponds to the first locking hole 1131 or the second locking hole 311. Thus, it avoids the second rotating member 32 from swinging along the first rotating axis 111 and the second rotating axis 112 at the same time. The cooperation between the elastic element 332 and the locking pin 331 can ensure the locking pin 331.

[0109] In some implementations, such as Figures 5-11 As shown, the cover portion 13 and the supporting portion 12 are in a state of being far apart from each other, and in the width direction of the supporting portion 12, the first rotating shaft 111 is far away from the cover portion 13 relative to the second rotating shaft 112 (e.g., Figure 11(As shown in L6). The width direction of the support portion 12 is perpendicular to the axis of the first rotating shaft 111. When the cover portion 13 drives the functional component A2 to rotate along the second rotating shaft 112 to the support portion 12, the side of the functional component A2 near the shell portion A1 corresponds to the processing area A11.

[0110] Specifically, when the phone screen rotates 90 degrees along the second hinge 112, the side of the phone screen closest to the second hinge 112 aligns with the side of the mid-frame closest to the second hinge 112. Simultaneously, the side of the phone screen furthest from the second hinge 112 also aligns with the side of the mid-frame furthest from the second hinge 112. This allows operators to directly use adhesive to install the phone screen and mid-frame together.

[0111] In some implementations, such as Figure 4 As shown, the unlocking pin 221 includes a first unlocking pin 221 and a second unlocking pin 223. The driving pin 224 includes a first driving pin 222 and a second driving pin 224.

[0112] Figure 12 This is an exploded view of the transmission unit 21 in this embodiment. Figure 13 This is a schematic diagram of the motion state of the transmission unit 21 in this embodiment.

[0113] Further reference Figure 12 and Figure 13 As shown, the drive assembly 2 in this embodiment includes a mounting frame 23 and a transmission part 21. The transmission part 21 includes a first driven rocker arm 211, a second driven rocker arm 212, a driving rocker arm 213, and a connecting rod 214. The first driven rocker arm 211 has a first hinge end 2111 and a third hinge end 2112, and the second driven rocker arm 212 has a second hinge end 2121 and a fourth hinge end 2122. The first hinge end 2111 and the second hinge end 2121 are hinged to the mounting frame 23, and the two ends of the connecting rod 214 are respectively hinged to the third hinge end 2112 and the fourth hinge end 2122. A first driving pin 222 and a second driving pin 224 are respectively disposed on the first driven rocker arm 211 and the second driven rocker arm 212, and a first unlocking pin 221 and a second unlocking pin 223 are disposed on the mounting frame 23.

[0114] The active rocker arm 213 drives the first driven rocker arm 211 and the second driven rocker arm 212 to swing together via the adapter rod 214, and the distance from the first hinge end 2111 to the first drive pin 222 is less than the distance from the second hinge end 2121 to the second drive pin 224 (e.g., Figure 13 (As shown by the mid-distance L1 and distance L2).

[0115] Therefore, on the one hand, by using the active swing arm 213 to drive the first driven swing arm 211 and the second driven swing arm 212 to swing together, the driving method of the operating component 1 is simplified. At the same time, by configuring the distance L1 to be less than the distance L2, the operating component 1 can be well adapted to the rotating structure on the first rotating part 11 when the first driven swing arm 211 and the second driven swing arm 212 alternately drive it.

[0116] Specifically, when the first drive pin 222 is inserted into the drive hole 321, the first hinge end 2111 is in a corresponding state with the first rotating shaft 111, so that the first drive pin 222 can drive the cover 13 to rotate along the first rotating shaft 111.

[0117] Conversely, when the second drive pin 224 is inserted into the drive hole 321, the second hinge end 2121 is in a corresponding state with the second rotating shaft 112, so that the second drive pin 224 can drive the cover 13 to rotate along the second rotating shaft 112.

[0118] In some implementations, such as Figure 13 As shown, the distance from the first hinge end 2111 to the third hinge end 2112 is greater than the distance from the second hinge end 2121 to the fourth hinge end 2122 (distance L4 is greater than distance L3).

[0119] The active rocker arm 213 has a drive groove 2131, and the transmission part 21 also includes a roller 215, which is disposed on the active rocker arm 213 and extends into the drive groove 2131.

[0120] The active swing arm 213 swings towards the support part 12 at a predetermined angle (angle a3), the roller 215 rolls along the drive groove 2131 and drives the adapter rod 214 to approach the support part 12, and at the same time the swing angle of the first driven swing arm 211 is greater than the swing angle of the second driven swing arm 212 (angle a1 is greater than angle a2).

[0121] Specifically, Figure 13 In state I, the cover 13 and the support 12 are perpendicular. When the active rocker arm 213 rotates counterclockwise by 40 degrees, the first driven rocker arm 211 rotates by 45 degrees, and the second driven rocker arm 212 rotates by 90 degrees. At the same time, the position of the drive assembly 2 is adjusted using the displacement assembly 4, so that the first unlocking pin 221, the first drive pin 222, the second unlocking pin 223, and the second drive pin 224 can respectively engage with the first rotating part 11 and drive the operation assembly 1 to move.

[0122] Therefore, the active rocker arm 213 can drive the cover 13 to rotate 45 degrees and 90 degrees respectively without changing the rotation angle, which greatly simplifies the driving method of the drive component 2 to the operation component 1.

[0123] In some implementations, such as Figures 12-13 As shown, the adapter rod 214 includes opposing long arms 2141 and short arms 2142. The long arms 2141 and short arms 2142 are perpendicular to each other and connected (e.g., Figure 13 (As shown at angle a4). The end of the short arm 2142 is connected to the third hinge end 2112, and the end of the long arm 2141 is connected to the fourth hinge end 2122.

[0124] Roller 215 is mounted on long arm 2141, second driven rocker arm 212 swings 90 degrees, and the length direction of short arm 2142 is perpendicular to the top surface of bearing part 12.

[0125] In this embodiment, the dimensional difference between the first driven pendulum 211 and the second driven pendulum 212 is increased by using the mutually perpendicular long arm 2141 and short arm 2142. This increases the difference in the swing amplitude between the first driven pendulum 211 and the second driven pendulum 212 while keeping the swing amplitude of the active pendulum 213 constant. On the other hand, when the second driven pendulum 212 swings 90 degrees, the long arm 2141 is horizontal, while the short arm 2142 is perpendicular to the support portion 12. This allows the active pendulum 213 to generate a force perpendicular to the top surface of the support portion 12 through the short arm 2142 (e.g., ...). Figure 13 As shown by the middle arrow a5, this ensures the installation accuracy between the phone screen and the mid-frame.

[0126] In some implementations, such as Figures 5-8 As shown, both the first rotating member 31 and the second rotating member 32 have a locking groove 34 and a guide slope 35. The two locking parts 33 are respectively disposed in the two locking grooves 34, and the elastic member 332 pushes the locking pin 331 out of the locking groove 34.

[0127] The cover 13 rotates away from the support portion 12, guiding the inclined surface 35 to abut against the end of the locking pin 331 and pushing the locking pin 331 towards the bottom of the locking groove 34 until the locking pin 331 is inserted into the first locking hole 1131, locking the seat 113 with the first rotating member 31. Alternatively, the locking pin 331 is inserted into the second locking hole 311, locking the seat 113 with the first rotating member 31.

[0128] Furthermore, such as Figure 8 As shown, the locking pin 331 includes a large end 3311 and a small end 3312. A groove 3313 is provided laterally on the large end 3311. When the large end 3311 slides within the locking groove 34, the locating pin 3314 passes through the groove 3313, and the two sidewalls of the groove 3313 can abut against the locating pin 3314 to restrict the position of the locking pin 331 within the locking groove 34. This prevents the elastic element 332 from completely ejecting the locking pin 331 from the locking groove 34.

[0129] In an alternative implementation, the assembly equipment in the above embodiments can operate as follows.

[0130] First, the operator places the mid-frame onto the support portion 12 and then places the circuit board A4 onto the mid-frame. Adhesive and release paper attached to the adhesive are provided on the inner side of the mid-frame. Simultaneously, the phone screen is placed onto the cover portion 13. The support portion 12 is equipped with a first clamping structure (such as...). Figure 3 As shown in the figure, a second clamping structure (not shown) is provided on the cover portion 13. The first clamping structure and the second clamping structure respectively fix the shell portion A1 and the functional component A2. A ribbon cable connects the functional component A2 and the circuit board A4. In this configuration, the ribbon cable is adjacent to one edge of the middle frame near the cover portion 13.

[0131] Secondly, the first unlocking pin 221 pushes the locking pin 331 out of the first lock hole 1131, allowing the first unlocking pin 221 to pass through the first lock hole 1131. Simultaneously, the first driving pin 222 drives the cover portion 13 to rotate 45 degrees along the first rotating shaft 111 towards the supporting portion 12, and then stops for a predetermined time. In this configuration, as... Figure 10 As shown, the operator can insert tweezers through the area between the support portion 12 and the cover portion 13 from the side of the insertion portion 22 away from the second rotating portion 14, reaching the side of the middle frame. Then, the release paper can be peeled off from the frame.

[0132] Next, the cover 13 is reset. During this process, the guide ramp 35, in cooperation with the locking pin 331, allows the locking pin 331 to move towards the locking groove 34. When the locking pin 331 and the first locking hole 1131 are in a corresponding state, the elastic member 332 allows the locking pin 331 to be reinserted into the first locking hole 1131. At this time, the aforementioned drive assembly 2 can be driven to gradually move away from the operating assembly 1, so that the first unlocking pin 221 can avoid the locking pin 331. Thus, the first rotating member 31 and the seat 113 are kept in a fixed state.

[0133] Next, the second unlocking pin 223 pushes the locking pin 331 out of the second locking hole 311, allowing the second unlocking pin 223 to pass through the second locking hole 311. Simultaneously, the second driving pin 224 drives the cover 13 to rotate 90 degrees along the second pivot 112, so that the phone screen is securely fastened to the top of the mid-frame. This process keeps the adhesive inside the mid-frame clean, preventing it from sticking to components such as the flex cable.

[0134] Finally, the cover 13 is reset again. During this process, the guide ramp 35, in cooperation with the locking pin 331, allows the locking pin 331 to move towards the locking groove 34. When the locking pin 331 and the second locking hole 311 are in a corresponding state, the elastic member 332 allows the locking pin 331 to be reinserted into the second locking hole 311. At the same time, the drive assembly 2 moves away from the operating assembly 1, ready for use by the next product A.

[0135] Figure 14 This is a schematic diagram of the structure of the displacement component 4 in this embodiment. Figure 15 This is a partial schematic diagram of the displacement component 4 in this embodiment.

[0136] In some implementations, such as Figures 14-15 As shown, the assembly equipment includes a displacement assembly 4. This displacement assembly 4 includes a movable plate 41, a stationary plate 42, and a slide rail section 43. The slide rail section 43 includes a first slide rail 431 and a second slide rail 432. The first slide rail 431 is disposed above the second slide rail 432 and perpendicular to it, while the second slide rail 432 is disposed on the stationary plate 42. A drive assembly 2 is disposed on the movable plate 41, and the movable plate 41 moves horizontally relative to the stationary plate 42 via the slide rail section 43.

[0137] The displacement component 4 is configured to drive the drive component 2 to move between a first stroke and a second stroke. In the first stroke, the first unlocking pin 221 is inserted into the first lock hole 1131, and in the second stroke, the second unlocking pin 223 is inserted into the second lock hole 311.

[0138] In this embodiment, during the first and second strokes of movement, the direction of movement of the drive component 2 is parallel to the axial direction of the first locking hole 1131, the second locking hole 311 and the drive hole 321, so that the insertion part 22 can connect the transmission part 21 and the first rotating part 11 together.

[0139] In some implementations, such as Figure 15 As shown, the stationary plate 42 has a first guide groove 424. The first guide groove 424 includes a first extension 421, a second extension 422 and a third extension 423. The third extension 423 is connected between the first extension 421 and the second extension 422. The extension directions of the first extension 421 and the second extension 422 are parallel to the axial direction of the drive hole 321.

[0140] The displacement assembly 4 also includes a first rotary driver 44, a guide rod 45, and a drive arm 46. The drive arm 46 includes a second guide groove 461. One end of the guide rod 45 is connected to the stationary plate 42, and the other end passes through the first guide groove 424 and extends into the second guide groove 461. The output shaft of the first rotary driver 44 is connected to the drive arm 46.

[0141] The first rotary actuator 44 is configured to drive the aforementioned drive arm 46 to oscillate intermittently. The second guide groove 461 causes the guide rod 45 to slide from one end of the first guide groove 424 to the other end. In the first extension 421, the drive assembly 2 is in the first stroke. In the second extension 422, the drive assembly 2 is in the second stroke.

[0142] In this embodiment, the rotational motion of the first rotary driver 44 is converted into the reciprocating motion of the drive assembly 2 by the cooperation of the second guide groove 461 and the first guide groove 424, so that the plug-in part 22 can be plugged into the second rotating part 14 and then separated after the operation is completed.

[0143] Figure 16 This is a circuit diagram of the assembly equipment in this embodiment.

[0144] In some implementations, such as Figure 16 As shown, the drive assembly 2 also includes a second rotary driver 24, the output shaft of which is connected to the active rocker arm 213.

[0145] The assembly equipment also includes a control circuit 5. The control circuit 5 is communicatively connected to the first rotary driver 44 and the second rotary driver 24. The control circuit 5 is configured to alternately output a first drive signal or a second drive signal to the first rotary driver 44, and to output a third drive signal to the second rotary driver 24, simultaneously driving the first rotary driver 44 and the second rotary driver 24 to move alternately. Specifically, the first drive signal and the second drive signal control the first rotary driver 44 to rotate in opposite directions, and the third drive signal controls the second rotary driver 24 to oscillate.

[0146] Specifically, the control circuit 5 first outputs a first drive signal, and then outputs a third drive signal to cause the cover 13 to rotate 45 degrees toward the support portion 12. After waiting for a predetermined time (e.g., 10 seconds), the operator can remove the release paper. Then, the control circuit 5 outputs a second drive signal and a fourth drive signal in sequence to cause the mobile phone screen to snap onto the casing A1.

[0147] In some implementations, such as Figures 6-7 As shown, the second rotating member 32 has a first positioning surface 322, and the seat 113 has a second positioning surface 114.

[0148] Further reference Figure 13 As shown, the length direction of the short arm 2142 is perpendicular to the top surface of the bearing part 12, and the first positioning surface 322 abuts against the second positioning surface 114.

[0149] In this embodiment, the first positioning surface 322 and the second positioning surface 114 limit the range of rotation of the cover 13 toward the support part 12, so as to avoid excessive pressure on the middle frame of the mobile phone screen, which could cause damage to the mobile phone screen or the middle frame.

[0150] Figure 17 This is a schematic diagram of the structure of the second rotating part 14 in this embodiment. Figure 18 This is an exploded view of the second rotating part 14 in this embodiment. Figure 17 The push rod of unlocking mechanism 7 is shown in the middle with a dotted line.

[0151] In some implementations, such as Figures 17-18 As shown, in this embodiment, the assembly equipment further includes a second rotating part 14 and an unlocking mechanism 7. The second rotating part 14 also includes a third rotating member 141, a fourth rotating member 142, a base 143, a positioning part 144, a third rotating shaft 148, and a fourth rotating shaft 149. The positioning part 144 includes a first positioning rod 1451, a second positioning rod 1452, a spring 146, and a synchronizing block 147. The fourth rotating member 142 has a third positioning hole 1421. The third rotating member 141 has a receiving groove 1411 for accommodating the positioning part 144.

[0152] Synchronization block 147 is fixedly connected to both the first positioning rod 1451 and the second positioning rod 1452. The third rotating shaft 148 and the fourth rotating shaft 149 correspond to the first rotating shaft 111 and the second rotating shaft 112, respectively. The base 143 has a first positioning hole 1431, a second positioning hole 1432, and a stop block 1433.

[0153] When the assembly equipment is in its initial state, the spring 146 pushes the synchronizing block 147 to drive the first positioning rod 1451 and the second positioning rod 1452 to be inserted into the first positioning hole 1431 and the second positioning hole 1432 respectively.

[0154] When the cover 13 rotates along the first pivot 111, the push rod of the unlocking mechanism 7 inserts into the first positioning hole 1431, so that the first positioning rod 1451 and the second positioning rod 1452 simultaneously move away from the first positioning hole 1431 and the second positioning hole 1432. The second positioning rod 1452 then inserts into the third positioning hole 1421, allowing the third rotating member 141 and the fourth rotating member 142 to rotate synchronously by 45 degrees along the third pivot 148. During this process, the end of the second positioning rod 1452 away from the fourth rotating member 142 also abuts against the stop block 1433, preventing the spring 146 from pushing the second positioning rod 1452 out of the third positioning hole 1421.

[0155] When the cover 13 rotates along the second pivot 112, the second positioning rod 1452 moves away from the fourth rotating member 142 under the action of the spring 146, so that the third rotating member 141 is fixed together with the base 143, and the fourth rotating member 142 rotates along the fourth pivot 149. This prevents the second rotating part 14 from rotating simultaneously along both the third pivot 148 and the fourth pivot 149. This ensures that the second rotating part 14 can cooperate with the first rotating part 11, improving the motion accuracy of the assembly equipment.

[0156] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
