For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figures 1 to 10 As shown, the electronic device protective cover button assembly machine of this embodiment is used to assemble the button 12 and the cover shell to form an electronic device protective cover. The button 12 has a guide matching groove 121 (as shown in the attached manual). Fig.11 As shown in the figure, the center of gravity of the key 12 is located on one side of the guide matching groove 121, and the electronic device protective cover includes an assembly position. The electronic device protective cover key assembly machine includes a frame 10, a control unit 102, an automatic feeding mechanism 103, a horizontal moving component 40 and a vertical moving component 50. Among them, the control unit 102 is installed on the frame 10; the automatic feeding mechanism 103 is located at one end of the frame 10, and is used to convey the key 12 and adjust the position state of the key 12 (that is, the forward and reverse position state of the key 12 itself relative to the position state in the positioning groove 410 described later). The horizontal moving component 40 and the vertical moving component 50 are located on the other end of the frame 10 along the feeding direction of the automatic feeding mechanism 103. The horizontal moving component 40 includes a first positioning seat 41, and the first positioning seat 41 is provided with a positioning groove 410 for fixing the key 12. The vertical moving assembly 50 includes a second positioning seat 51 for fixing the shell. The control unit 102 controls the positioning groove 410 to transport the key 12 to the top or bottom of the assembly position on the second positioning seat 51. The second positioning seat 51 is used to assemble the key 12 at the assembly position (pressing process). The automatic loading mechanism 103, the horizontal moving assembly 40 and the vertical moving assembly 50 are all electrically connected to the control unit 102.

[0041] As a further limitation of this embodiment, the automatic feeding mechanism 103 includes: a vibration source 100, a vibration disk 11 and a first conveying track 3, the vibration disk 11 has a discharge port 101, and the vibration disk 11 is drivingly connected to the power output end of the vibration source 100. The first conveying track 3 includes a first feed end 302 (that is, an end of the first conveying track 3 away from the positioning groove 410 in the technical solution described later) and a first discharge end 303 respectively arranged at both ends of the first conveying track 3, the first feed end 302 is connected to the discharge port 101, and the first discharge end 303 is used to convey the button 12. It can be understood that the direction of the discharge port 101 of the first conveying track 3 is also the direction of transporting the button 12.

[0042] Among them, the vibration source 100 provides a power source for the vibration disk 11 so that the vibration disk 11 drives the button 12 coming out of the discharge port 101 to move on the first conveying track 3 by vibrating in the vertical direction. The first conveying track 3 is provided with a first inclined surface 301 and a first guide portion 31. Among them, the first inclined surface 301 is inclined toward the ground from the direction from the center of gravity to the guide matching groove 121, and the first guide portion 31 is arranged on the first inclined surface 301 (in this embodiment, that is, the first inclined surface 301 is arranged on one side in the horizontal direction along the extension direction of the first conveying track 3, that is, it is inclined toward the ground). When the guide matching groove 121 of the button 12 is clamped in the first guide portion 31 (that is, the center of gravity position of the button 12 is fixed on the side close to the ground on the first inclined surface 301), the bottom end of the button 12 on the other side of the center of gravity relative to the guide matching groove 121 is pressed against the first inclined surface 301, so that the button 12 maintains the correct installation direction (the inclination angle or inclination mode of the first inclined surface 301 can be changed according to actual needs to achieve the desired installation direction) and is transported to the assembly position for installation. Correspondingly, when the button 12 comes out of the discharge port 101, the button 12 does not come out of the state where it is stuck on the first guide part 31 along the guide matching groove 121 (i.e., the state where the position close to the center of gravity of the button 12 is away from the first guide part 31 or other states), that is, when the bottom end of the end close to the center of gravity of the button 12 abuts against the first inclined surface 301, the button 12 will be in a tilted state, and will lose balance under the vibration of the vibration plate 11, and then fall from the first conveying track 3. The reverse button 12 is screened by the placement of the button 12 and the action of gravity, avoiding the problem of reverse installation of the button 12 and improving the feeding efficiency. Optionally, when the top position of the first guide portion 31 is higher than the end of the first inclined surface 301 away from the ground, the guide matching groove 121 of the key 12 is engaged with the first guide portion 31; or when the top position of the first guide portion 31 is lower than the end of the first inclined surface 301 away from the ground, the guide matching groove 121 of the key 12 is also engaged with the first guide portion 31, that is, there is always a limit member (first guide portion 31) at the center of gravity position on the key 12 to fix the key 12, so the key 12 with the correct installation direction will be selected and retained.

[0043] As a further limitation of the present invention, the first conveying track 3 is provided with a second guide portion 32, and the second guide portion 32 extends along the extension direction of the first conveying track 3, and is used to guide and position the transportation of the key 12. Among them, the side wall of the key 12 located on the other side of the center of gravity relative to the guide matching groove 121 abuts against the second guide portion 32. It can be understood that in this embodiment, the second guide portion 32 protrudes vertically upward from the end of the first inclined surface 301 away from the ground. In addition, there is a gap between the second guide portion 32 and the first guide portion 31 (the second guide portion 32 abuts against the side wall of the end of the key 12 close to the center of gravity, and the first guide portion 31 is engaged with the guide matching groove 121, so the second guide portion 32 and the first guide portion 31 are respectively located at the opposite ends of the key 12). It is understandable that the button 12 coming out of the discharge port 101 of the vibration plate 11 will present a variety of placement states. When the button 12 is transported to the first conveying track 3, the guide matching groove 121 of the button 12 is adapted to the first guide portion 31, and the side wall of the button 12 at one end away from the center of gravity relative to the guide matching groove 121 abuts on the second guide portion 32, and the bottom wall of the button 12 at one end away from the center of gravity relative to the guide matching groove 121 abuts on the first inclined surface 301, completing the guiding and supporting function for the other end of the button 12. The button 12 will be positioned by the first guide portion 31 to ensure that it will not fall down due to unstable center of gravity, thereby completing the wrong material screening function. And the button 12 that maintains the correct installation direction is smoothly transported to the assembly position for the next installation operation under the guiding action of the second guide portion 32 and the first guide portion 31.

[0044] As a further limitation of the present invention, the vibration disk 11 includes a second conveying track 2. The second conveying track 2 is connected between the first conveying track 3 and the discharge port 101, and the second conveying track 2 includes a second feed end 202 and a second discharge end 203 respectively arranged at both ends of the second conveying track 2. The second feed end 202 is connected to the discharge port 101, and the second discharge end 203 is connected to the first feed end 302 (that is, the end of the first conveying track 3 away from the positioning groove 410). The second conveying track 2 is provided with a second inclined surface 201 and a third guide portion 21, and the second inclined surface 201 is parallel to the first inclined surface 301 (it can be understood that the button 12 coming out of the discharge port 101 will be inclined along the inclination angle of the second inclined surface 201 due to the effect of gravity, and the end of the button 12 close to the center of gravity can be inclined toward the ground, or the end away from the center of gravity can be inclined toward the ground). Optionally, the second conveying track 2 and the first conveying track 3 are connected to each other at the connection (that is, the connection between the second discharge end 203 and the first feed end 302), that is, the posture (inclination angle and direction) of the key 12 on the second conveying track 2 and the first conveying track 3 is consistent. The second inclined surface 201 ensures that the key 12 coming out of the discharge port 101 maintains an inclined trend, which can increase the feeding rate. And just at the connection between the first conveying track 3 and the second conveying track 2, the guide matching groove 121 of the key 12 in the correct installation direction (the key 12 with one end close to the center of gravity tilted toward the ground) just fits with the first guide part 31, so that the key 12 is smoothly transported to the first conveying track 3. On the contrary, the key with one end away from the center of gravity tilted toward the ground (it can also be understood that the guide matching groove 121 of the key 12 is not limited and the two ends are unbalanced) will fall down and be screened out due to loss of balance. Correspondingly, the button 12 will tend to slide down on the second conveying track 2 due to the effect of gravity, and the third guide portion 21 protrudes vertically upward from the end of the second inclined surface 201 close to the ground, and is extended along the extension direction of the second conveying track 2, so that one end of the button 12 can abut against the third guide portion 21 (it can be understood that the end of the button 12 close to the center of gravity, that is, the heavier end of the button 12 will preferentially abut against the third guide portion 21), and is in an inclined state and then transported to the first conveying track 3.

[0045] Furthermore, at the connection position between the second conveying track 2 and the first conveying track 3, the first guide portion 31 is located between the third guide portion 21 and the second guide portion 32. It can be understood that when the bottom end of the end near the center of gravity of the key 12 abuts against the first inclined surface 301, the key 12 whose end near the center of gravity (one end of the guide matching groove 121) abuts against the third guide portion 21 can be the key 12 in the correct installation direction, and at this time, the guide matching groove 121 on the key 12 and the first guide portion 31 just correspond to each other. That is, at the connection position between the second conveying track 2 and the first conveying track 3, the guide matching groove 121 on the button 12 just matches with the first guide part 31 (since the guide matching groove 121 is arranged in the direction of the first inclined surface 301, therefore, in the extension direction of the first inclined surface 301, there is still a distance between the position of the guide matching groove 121 and the third guide part 21, and the first guide part 31 is located between the third guide part 21 and the second guide part 32, so that the button 12 has enough space to enter the first conveying track 3), so that the button 12 can be smoothly clamped on the first guide part 31, and the bottom wall of the end of the button 12 away from the center of gravity position abuts against the second guide part 32, completing the transfer and transportation of the button 12 and increasing the loading rate.

[0046] As a further limitation of the present invention, the second conveying track 2 is provided with a fourth guide portion 22, which protrudes vertically upward from one end of the second inclined surface 201 on the horizontal direction away from the ground, and is extended along the extension direction of the second conveying track 2. At the connection position of the second conveying track 2 and the first conveying track 3, the second guide portion 32 is located between the fourth guide portion 22 and the first guide portion 31, and the spacing between the fourth guide portion 22 and the first guide portion 31 is less than or equal to the spacing between the second guide portion 32 and the first guide portion 31. It can be understood that the vibration plate 11 is in a state of vibration during the entire feeding process, and the key 12 on the second conveying track is in an inclined state and is prone to falling (when the pressing operation is performed at the assembly position, the vibration source 100 is still working continuously to continuously transmit the key 12, so the key 12 will gather on the second conveying track 2) The fourth guide portion 22 can prevent the key 12 from falling. In addition, it is ensured that the key 12 has sufficient space to enter the first conveying track 3, further improving the feeding rate.

[0047] As a further limitation of the present invention, the vibration disk 11 includes a third conveying track 4, the third conveying track 4 has a third feed end 402 and a third discharge end 403, the third discharge end 403 is connected to the second feed end 202 (that is, the end of the second conveying track 2 away from the first conveying track 3), and the third feed end 402 is connected to the discharge port 101. That is, the third conveying track 4 is located between the second conveying track 2 and the discharge port 101. Optionally, the third conveying track 4 is spirally arranged inside the vibration disk 11, and the cross-section of the third conveying track 4 presents a "concave" structure, which plays a technical effect of transporting the key 12 and preventing the key 12 from falling.

[0048] As a further limitation of the present invention, the automatic feeding mechanism 103 further includes a guiding structure 6, the guiding structure 6 includes a cavity 601 for the key 12 to pass through, the cavity 601 has a fourth feed end 602 (an end on the first conveying track 3 away from the discharge port 101) and a fourth discharge end 603, the fourth feed end 602 is connected to the first discharge end 303, and the fourth discharge end 603 is connected to the positioning groove 410. The cross-sectional profile of the cavity 601 is the same as the profile of the key 12, and the cross-sections of the cavity 601 at different intervals in the extension direction of the guiding structure 6 form angles with each other. That is, the fourth discharge end 603 is twisted at a predetermined angle relative to the fourth feed end 602 to achieve a predetermined angle for flipping the key 12 entering the cavity 601. It can be understood that the key 12 coming out of the first conveying track 3 is in a state of an inclined angle, but because it is necessary to ensure that the key 12 is positioned in conjunction with the first positioning seat 41 at the positioning groove 410 (the final installation angle of the key 12 is determined according to the angle of the first positioning seat 41), the guide structure 6 achieves the effect of adjusting the angle of the key 12 to facilitate rapid positioning of the key 12.

[0049] As a further limitation of this embodiment, the automatic feeding mechanism 103 further includes a second pneumatic source 33 and a second air inlet pipe 34, the output end of the second pneumatic source 33 is pneumatically connected to one end of the second air inlet pipe 34, and the other end of the second air inlet pipe 34 is connected to the inner cavity of the cavity 601. Since the cross-section of the cavity 601 of the guiding structure 6 is constantly changing in the direction in which it extends, there will be a certain resistance that prevents the button 12 from passing through quickly, and the other end of the second air inlet pipe 34 is arranged toward the fourth feeding end 602, for blowing the button 12 into the cavity 601.

[0050] As a further limitation of this embodiment, the first pneumatic source 413 and the first air inlet pipe 414, the output end of the first pneumatic source 413 is pneumatically connected to one end of the first air inlet pipe 414, and the other end of the first air inlet pipe 414 is arranged toward the fourth discharge end 603, for blowing the key 12 to the positioning groove 410. Optionally, the end of the automatic feeding mechanism 103 connected to the positioning groove 410 (i.e., the fourth discharge end 603) is generally relatively fixed, and is far away from the vibration source 100, and the power of the vibration source 100 is insufficient, and the first pneumatic source 413 continuously blows air to the first air inlet pipe 414, so that the key 12 continuously enters the positioning groove 410.

[0051] As a further limitation of the present invention, the automatic loading mechanism 103 also includes a recovery area 110, which is arranged at a position on the vibration disk 11 corresponding to the first conveying track 3. The recovery area 110 is connected to the discharge port 101, and can directly recover the buttons 12 in the opposite direction and send them into the first conveying track 3 for secondary adjustment.

[0052] like Fig.12 and Fig.13 As shown, in this embodiment, after the control unit 102 controls the positioning groove 410 to move horizontally to the lower side of the assembly position, the control unit 102 controls the second positioning seat 51 to descend. That is, the first positioning seat 41 is pre-set at a place opposite to the assembly position (the assembly position on the second positioning seat 51), and the control unit 102 drives the horizontal moving assembly 40 to move along the horizontal projection direction of the line connecting the first positioning seat 41 and the second positioning seat 51 to complete the alignment work with the assembly position, and the control unit 102 drives the vertical moving assembly 50 to move along the vertical projection direction of the line connecting the first positioning seat 41 and the second positioning seat 51 to complete the pressing work between the first positioning seat 41 and the second positioning seat 51. After the control unit 102 controls the horizontal moving assembly 40 to make the positioning groove 410 correspond to the assembly position, the control unit 102 controls the vertical moving assembly 50 to move and press, completing the rapid assembly of the key 12, thereby improving the production efficiency and the consistency of the key feel.

[0053] As a further limitation of this embodiment, the first positioning seat 41 is provided with a feed track seat 412 (taking the reader facing the attached figure of the specification as an example, the frame 10 can be placed on the ground), and the feed track seat 412 is located on one side of the positioning slot 410. Among them, the feed track seat 412 is provided with a conveying slot 4121, one end of the conveying slot 4121 is connected to the positioning slot 410, and the other end of the conveying slot 4121 is used to connect with the automatic feeding mechanism 103 (specifically, the other end of the conveying slot 4121 is connected to the fourth discharge end 603; or it can be understood that the other end of the conveying slot 4121 is connected to the end of the guide structure 6 away from the discharge port 101). It can be understood that the key 12 located in the conveying slot 4121 on the feed track seat 412 is the next key 12 to be installed, and the key 12 entering the positioning slot 410 is the key 12 to be installed.

[0054] As a further limitation of this embodiment, the electronic device protective cover button assembly machine includes a push cylinder 431 and a pressure head 430 electrically connected to the control unit 102. Among them, a positioning piece 420 is provided on the feed track seat 412, and the positioning piece 420 covers the conveying groove 4121. The positioning piece 420 is provided with a positioning hole 421 opposite to the pressure head 430. The output end of the push cylinder 431 is connected to the pressure head 430, and the pressure head 430 can be lifted and moved (in the vertical direction of the lifting displacement in this embodiment) under the drive of the push cylinder 431, that is, the pressure head 430 can be driven by the push cylinder 431. Move away from or approach each other with the positioning hole 421. Furthermore, the pressure head 430 can be adapted to the positioning hole 421, and the pressure head 430 can pass through the positioning hole 421 to abut against the next key 12 to be installed (it can be understood that the key 12 located in the conveying groove 4121 on the feed track seat 412 is the next key 12 to be installed, and the key 12 entering the positioning groove 410 is the key 12 to be installed) to limit the key 12 (the next key 12 to be installed) that is ready to enter the positioning groove 410. Optionally, the end of the pressure head 430 that contacts the next key 12 to be installed is a flexible component (the shape of the pressure head 430 can be a trumpet shape, which can increase the adsorption force on the key 12 to be installed), such as a deformable elastic component such as silicone rubber, so as to prevent the rigid component from directly contacting the key 12 to be installed, causing scratches or crushing to the key 12. The feed track seat 412 is installed on the frame 10, which is convenient for the pressure head 430 to apply force to the next key 12 to be installed, thereby enhancing the stability of the device.

[0055] Specifically, when the button 12 (which can be considered as the next button 12 to be installed before entering the positioning groove 410) enters the positioning groove 410 and becomes the button 12 to be installed, the automatic feeding mechanism 103 continues to work, that is, the button 12 to be installed will be subjected to the force from the direction of the feeding track seat 412 (the wind force of the first pneumatic source 413 and the second pneumatic source 33), and the direction of the feeding track seat 412 is still continuously transmitting the next button 12 to be installed (that is, when the button 12 to be installed is placed inside the positioning groove 410, the opening of the feeding track seat 412 near the positioning groove 410 will continue to transmit the next button 12 to be installed). Among them, the positioning sheet 420 is a sheet-like structure covering the conveying groove 4121. When the pressure head 430 moves downward for a distance under the action of the push cylinder 431, it reaches the position matching the positioning hole 421 and abuts against the side wall position of the next button 12 to be installed (in this embodiment, it can be understood as the top position of the next button 12 to be installed). The positioning piece 420 can prevent the next key 12 to be installed (i.e., the key 12 that has not entered the positioning groove 410 and is still on the feed track seat 412) from being flipped up or squeezed out of the feed track seat 412 due to the feeding driving force (the first pneumatic source 413 and the second pneumatic source 33) of the upstream automatic feeding mechanism 103 (i.e., it is necessary to limit the next key 12 to be installed from continuing to move toward the positioning groove 410. Because, at this time, there is already a key 12 to be installed in the positioning groove 410, and the positioning groove 410 will drive the key 12 to be installed to perform the next step of alignment and pressing). Optionally, the positioning hole 421 is set at the position closest to the positioning groove 410 on the feed track seat 412, that is, the pressing head 430 will abut against the next key 12 to be installed that is closest to the positioning groove 410. It can be understood that when the button 12 to be installed in the positioning groove 410 completes the pressing step, the control unit 102 controls the positioning groove 410 to return to its original position, and the pressure head 430, under the control of the control unit 102, can automatically release the limit on the next button 12 to be installed (that is, the pressure head 430 will be separated from the next button 12 to be installed, and the next button 12 to be installed can enter the positioning groove 410 under the action of the wind force of the first pneumatic source 413 and the second pneumatic source 33).

[0056] As a further limitation of this embodiment, the electronic device protective cover button assembly machine also includes a first detection unit 460, the first detection unit 460 is electrically connected to the control unit 102, and the first detection unit 460 corresponds to the positioning groove 410 (it can be understood that the first detection unit 460 is arranged opposite to the positioning groove 410, that is, the first detection unit 460 can be installed on the frame 10 or on the output end of the push cylinder 431) for sensing whether the button 12 to be installed is assembled on the positioning groove 410 (to avoid missing installation), so as to send a signal instruction to the control unit 102, so that the control unit 102 makes the next operation. Optionally, the first detection unit 460 can be an infrared sensing transmitting tube or an ultrasonic transmitting tube. It can be understood that after the first detection unit 460 detects that there is a button 12 to be installed in the positioning groove 410, it sends a command information to the control unit 102, and the control unit 102 controls the positioning groove 410 to move so that the positioning groove is aligned with the second positioning seat 51. Correspondingly, when it is detected that there is no button 12 to be installed in the positioning groove 410, the control unit 102 can issue a corresponding alarm message to prompt the operator to manually adjust the button 12 to be installed or require the operator to reinstall it.

[0057] As a further limitation of this embodiment, the positioning groove 410 is provided with a first suction port 440 and a key fixing power source 441, wherein the key fixing power source 441 is electrically connected to the control unit 102, and the first suction port 440 is pneumatically connected to the key fixing power source 441. The first suction port 440 is provided on the groove wall of the positioning groove 410 and is arranged toward the key to be installed 12. When the first detection unit 460 senses that there is a key to be installed 12 in the positioning groove 410, the control unit 102 drives the key fixing power source 441 to work to generate an adsorption force on the key to be installed 12 located inside the positioning groove 410 so that the key to be installed 12 is fixed inside the positioning groove 410. Optionally, the key fixing power source 441 can be in the working mode all the time, that is, it will always generate a downward adsorption force inside the positioning groove 410; or it can be that it works only after the first detection unit 460 sends a command information to the control unit 102, that is, it works intermittently.

[0058] like Fig.14 As shown, the horizontal moving assembly 40 includes an elastic member 450 and a third positioning seat 451, the third positioning seat 451 is provided with a positioning column 452, the elastic member 450 is sleeved on the positioning column 452, and connects the first positioning seat 41 and the third positioning seat 451. It can be understood that when the first positioning seat 41 and the second positioning seat 51 are pressed against each other, the elastic member 450 is used to buffer the third positioning seat 451 and the first positioning seat 41. Specifically, the elastic member can be an elastic member such as a spring, or a torsion spring, etc. Optionally, a positioning hole that matches the positioning column 452 is provided on the first positioning seat 41 to prevent the first positioning seat 41 from shifting when the elastic body moves.

[0059] As a further limitation of this embodiment, the vertical moving assembly 50 includes at least one second suction port 520 and a casing fixing power source 521, and the casing fixing power source 521 is electrically connected to the control unit 102. The output end of the casing fixing power source 521 is pneumatically connected to the second suction port 520, and the second suction port 520 is arranged on the second positioning seat 51 for limiting the casing. It can be understood that the electronic equipment protective cover button assembly machine needs to be equipped with at least one operator, who is required to install the casing of the electronic equipment protective cover on the second positioning seat 51, and then use the casing fixing power source 521 to generate adsorption force, and the second suction port 520 contacts the casing (optionally, the second suction port 520 corresponds to the larger side of the casing and is a non-appearance surface, so that the casing is positioned more firmly), and at the same time, to prevent people from manually fixing and scratching the casing, the appearance defect rate is reduced to a certain extent. Specifically, the housing is installed on the side of the second positioning seat 51 close to the operator (and the appearance side of the housing is close to the operator), that is, the mutual movement between the horizontal moving assembly 40 and the vertical moving assembly 50 is on the side area away from the operator on the second positioning seat 51. In addition, the number of the second suction ports 520 can be multiple, evenly arranged on the second positioning seat 51 to prevent deformation of the housing.

[0060] As a further limitation of this embodiment, the second positioning seat 51 includes a second detection unit 530, which is arranged on the second positioning seat 51 and corresponds to the shell of the electronic device protective cover, and the second detection unit 530 is electrically connected to the control unit 102. When the second detection unit 530 senses that a shell is installed on the second positioning seat 51 (that is, after the operator completes the installation of the shell), the control unit 102 drives the shell fixing power source 521 to work, and generates an adsorption force on the shell located on the second positioning seat 51 so that the shell is fixed on the second positioning seat 51. Optionally, the shell fixing power source 521 can be in working mode all the time, that is, it will always generate an adsorption force on the contact surface of the shell on the second positioning seat 51. It can also be that the second detection unit 530 works after sending a command information to the control unit 102, that is, it works intermittently. Specifically, the second detection unit 530 can realize the detection process through infrared detection and other devices, or it can realize the detection function through a touch detector.

[0061] As a further limitation of this embodiment, the vertical moving assembly 50 includes a lifting cylinder 540, and the horizontal moving assembly 40 includes a translation cylinder 470, and the lifting cylinder 540 and the translation cylinder 470 are both electrically connected to the control unit 102. A matching portion 510 is provided on the second positioning seat 51, and specifically, the matching portion 510 matches the shape of the first positioning seat 41 (a jig for positioning the button 12 to be installed), that is, the matching portion 510 corresponds to the assembly position on the shell. Optionally, the matching portion 510 is a notch structure, and the first positioning seat 41 can be displaced to a position that is compatible with the notch structure under the control of the control unit 102 (that is, the alignment work between the first positioning seat 41 and the second positioning seat 51 is completed, and the next step of pressing can be performed). Among them, the output end of the lifting cylinder 540 is driven and connected to the second positioning seat 51, and the third positioning seat 451 is driven and connected to the translation cylinder 470. The control unit 102 controls the lifting cylinder 540 to drive the first positioning seat 41 to move toward the second positioning seat 51 (in this embodiment, it can be understood that the first positioning seat 41 is pre-fixed in the horizontal position opposite to the notch on the second positioning seat 51, and the first positioning seat 41 is horizontally displaced toward the second positioning seat 51) to make the matching part 510 match the first positioning seat 41 (alignment process), and then the control unit 102 controls the translation cylinder 470 to drive the second positioning seat 51 to move toward the first positioning seat 41 (in this embodiment, it can be understood that the second positioning seat 51 moves downward toward the first positioning seat 41) and press each other, thereby completing the assembly process of the key 12 to be installed and the shell.

[0062] Specifically, the mating portion 510 has the same size as the first positioning seat 41, that is, the mating position of the first positioning seat 41 and the mating portion 510 is the assembly position of the key 12, that is, the first positioning seat 41 (the key 12 to be installed) moves to the position on the second positioning seat 51 that matches with the inside of the shell, and the key 12 to be installed will eventually be pressed into the shell from the internal position of the shell.

[0063] It can be understood that the first detection part 460 corresponds to the positioning groove 410. After the first detection part 460 senses that there is a button 12 to be installed on the positioning groove 410, it sends a signal command to the control part 102, and the control part 102 drives the translation cylinder 470 to start working. The first positioning seat 41 is driven by the translation cylinder 470 to drive the first positioning seat 41 to move toward the second positioning seat 51 along the horizontal projection direction of the line connecting the first positioning seat 41 and the second positioning seat 51 (that is, the horizontal direction in this embodiment) (at this time, the end of the feed track seat 412 facing the positioning groove 410 has no fixed structure, that is, it is in an open state) until it stops at a position on the second positioning seat 51 that is mutually adapted with the matching part 510. At the same time, the control unit 102 drives the push cylinder 431 to drive the pressure head 430 to move downward until it corresponds to the position of the feed track seat 412, that is, when the pressure head 430 corresponds to the positioning hole 421. At this time, the pressure head 430 just abuts against the side wall position of the next button 12 to be installed to prevent the next button 12 to be installed closest to the positioning groove 410 from being blown off by the feeding driving force of the feeding mechanism. The first positioning seat 41 stops moving when the first positioning seat 41 is driven by the translation cylinder 470 to move to the position of the matching portion 510 (at this time, it can be understood that the button 12 to be installed on the positioning groove 410 corresponds to the assembly position inside the shell). Then, the control unit 102 drives the horizontal moving component 40 to move along the horizontal projection direction of the line connecting the first positioning seat 41 and the second positioning seat 51 (that is, the control unit 102 drives the second positioning seat 51 to move toward the direction of the first positioning seat 41 (vertically move downward), so that the button 12 to be installed is squeezed into the assembly position, that is, the position where the button 12 to be installed is installed on the shell (the button 12 to be installed is installed from the inner area of ​​the shell to the outside of the shell), that is, the pressing step is performed. It can be understood that the displacement of the horizontal moving component 40 is the process of alignment, and the displacement of the vertical moving component 50 is the process of pressing. Furthermore, it can be understood that, when the first detection unit 460 senses that there is a button 12 to be installed in the positioning groove 410, the control unit 102 drives the button fixing power source 441 to work to generate an adsorption force on the button 12 to be installed located inside the positioning groove 410 so that the button 12 to be installed is fixed inside the positioning groove 410, and when the first positioning seat 41 is driven by the translation cylinder 470 to drive the first positioning seat 41 to move toward the second positioning seat 51 along the horizontal projection direction of the line connecting the first positioning seat 41 and the second positioning seat 51, and in the subsequent pressing process, the button fixing power source 441 is always working normally.

[0064] As a further limitation of this embodiment, the assembly method of the first positioning seat 41 and the output end of the translation cylinder 470, and the assembly method of the output end of the lifting cylinder 540 and the second positioning seat 51 (specifically, it can be the third positioning seat 451) can be assembled by connecting with screws or positioning pins to achieve the purpose of quick disassembly, so as to be suitable for the assembly of various models of products.

[0065] As a further limitation of this embodiment, the control unit 102 can control multiple automatic loading mechanisms 103 to work simultaneously, that is, the electronic device protective cover key assembly machine can continuously install multiple keys 12 at the same time (correspondingly, multiple assembly positions are provided on the shell of the electronic device protective cover).

[0066] As a further limitation of this embodiment, a safety light curtain 104 is provided on one side of the frame 10 close to the second positioning seat 51, that is, on the side of the casing installation station. After the operator fixes the casing on the second positioning seat 51, the safety light curtain 104 senses that there is no manual activity in the operation area, and will issue an activity instruction to continue working, that is, the control unit 102 controls the automatic feeding mechanism 103, the horizontal moving assembly 40 and the vertical moving assembly 50 to continue working. If an emergency occurs, after the safety light curtain 104 senses it, the control unit 102 preferentially controls the push cylinder 431 to descend to fix the button 12 on the feed track seat 412 first, to prevent the button 12 from blocking the transport track (the transport path from the guide structure 6 to the positioning groove 410). Optionally, the safety light curtain 104 can also be an inductive detection sensor device such as an infrared or safety grating.

[0067] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
