[0002] With the development of science and technology and the progress of humanities, mobile phones have become one of the indispensable electronic products in people's daily lives. Before mobile phones leave the factory, various tests must be done to pick out defective products and avoid adding workload to subsequent after-sales service.

[0003] In the existing automatic test lines for mobile phone functions, in the process of the mobile phone coming out of the conveyor line and being sent to the testing mechanism, it is often necessary to use a transfer mechanism to transfer the mobile phone between devices.

[0034] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0035] See also Figures 1 to 3 , Figure 5 and Fig.12The mobile phone function automatic test line 100 of the present invention includes a protective cover 1, a loading mechanism 2 for loading mobile phones, a conveying device 3 for transmitting mobile phones, a testing device 4 for testing the functions of mobile phones, and a transfer device 5 for transferring mobile phones between the conveying device 3 and the testing device 4. The transfer device 5 is arranged between the conveying device 3 and the testing device 4, and the protective cover 1 covers the transfer device 5 to reduce the interference of the external environment on the transfer device 5, such as reducing dust and keeping it clean. The conveying device 3 includes a horizontally movable conveying surface 31, and the conveying surface 31 is provided with a to-be-tested area 3a and a tested area 3b. The to-be-tested area 3a and the tested area 3b are arranged side by side and parallel to each other along the width direction of the conveying surface 31. The testing device 4 is provided with a pre-stored station 4a and a testing station 4b with the same height. The transfer device 5 includes a robot 51 and a synchronous pick-and-place device 52 installed on the robot 51. The synchronous pick-and-place device 52 includes a base plate 521 and two pick-and-place units 522 for clamping a mobile phone. The pick-and-place units 522 are installed on the base plate 521 at intervals along the left and right directions. When one of the pick-and-place units 522 clamps a mobile phone, the other pick-and-place unit 522 releases the mobile phone. The robot 51 drives the synchronous pick-and-place device 52 to transfer between the conveying device 3 and the testing device 4. For the convenience of description, the two pick-and-place units 522 are respectively referred to as the first pick-and-place unit 522a and the second pick-and-place unit 522b. For example, when the synchronous pick-and-place device 52 is located above the conveying device 3, the first pick-and-place unit 522a clamps the mobile phone located in the area to be tested 3a, and the second pick-and-place unit 522b releases the mobile phone that has passed the test to the tested area 3b; when the synchronous pick-and-place device 52 is located next to the testing device 4, the second pick-and-place unit 522b clamps the mobile phone located in the testing station 4b, and the first pick-and-place unit 522a releases the mobile phone to the pre-stored station 4a. In other words, the synchronous pick-and-place device 52, driven by the robot 51, moves the first pick-and-place unit 522a between the area to be tested 3a and the pre-stored station 4a, and moves the second pick-and-place unit 522b between the tested area 3b and the testing station 4b. Specifically, the feeding mechanism 2 is arranged at the head end of the conveying device 3, and the conveying direction of the feeding mechanism 2 is perpendicular to the conveying direction of the conveying device 3. For example, in the present embodiment, there are two feeding mechanisms 2, which are respectively arranged on both sides of the conveying device 3 along the width direction, and the two feeding mechanisms 2 are staggered along the length direction of the conveying device 3. The feeding mechanism 2 conveys the mobile phone to the head end of the conveying device 3. In the present embodiment, the test devices 4 are in groups of four, and a group of test devices 4 is stacked on each other in the up-down and left-right directions. Of course, in other embodiments, the test devices 4 may be a single group or a group of two, so it is not limited to this. One group of test devices 4 corresponds to one transfer device 5. Specifically, in the present embodiment, the test devices 4 and the transfer devices 5 are three groups respectively. Of course, in other embodiments, the test devices 4 and the transfer devices 5 may be one group, two groups, four groups or five groups, so it is not limited to this.It is understandable that the structure and principle of the conveying device 3 are well known to those skilled in the art, so they will not be described in detail here. More specifically, as follows:

[0036] See also Figure 4 The feeding mechanism 2 is provided with an input end 2a and an output end 2b along its conveying direction. The feeding mechanism 2 includes a horizontally movable conveyor belt 21, a positioning plate 22 covering the conveyor belt 21, and a pushing mechanism 23 located on the output end 2b. The positioning plate 22 is provided with a plurality of positioning holes 221 evenly spaced along the conveying direction. With the help of the positioning holes 221, it is beneficial to position the mobile phone while discharging the material. The pushing mechanism 23 pushes the arriving mobile phone laterally into the head end of the conveying device 3. The output end 2b has a mounting platform 24, and a material sensor (not shown in the figure) is provided on the mounting platform 24. When the mobile phone is located at the output end 2b of the conveyor belt 21, the material sensor senses it, and the pushing mechanism 23 pushes the mobile phone to the head end of the conveying device 3, and the conveying device 3 continues to convey it. Specifically, the pushing mechanism 23 includes a pushing cylinder 231 and a pushing plate 232 connected to the output end of the pushing cylinder 231. The pushing cylinder 231 drives the pushing plate 232 to push the mobile phone to the head end of the conveying device 3 along a direction perpendicular to the conveying direction of the conveyor belt 21.

[0037] See also Figure 6 , the test device 4 includes a box 41, a test assembly (not shown), a first carrier 42, a second carrier 43, a transfer device 44 and a drive device 45. The box 41 is provided with an opening 46 at the test station 4b, the drive device 45 is installed outside the box 41, the second carrier 43 is arranged at the output end of the drive device 45, the drive device 45 drives the second carrier 43 to enter and exit the opening 46, and the first carrier 42 is fixed outside the box 41 and located at the pre-stored station 4a. It can be understood that the first carrier 42 and the second carrier 43 are at the same height, so as to facilitate the synchronous pick-and-place device 52 to pick and place the mobile phone at the same time. The transfer device 44 is arranged outside the box 41 and located above the first carrier 42 and the second carrier 43. The transfer device 44 transfers the mobile phone located in the first carrier 42 to the second carrier 43, and the test assembly is arranged in the box 41. It can be understood that when the second carrier 43 enters the box 41 with the mobile phone, the test assembly tests the mobile phone. The test components are well known to those skilled in the art and will not be described in detail here.

[0038] See also Figure 7 as well as Figure 8The transfer device 44 includes a base 441, a lifting mechanism 442, a transverse mechanism 443 and a material picking module 444. The lifting mechanism 442 is installed on the base 441, the transverse mechanism 443 is installed on the output end of the lifting mechanism 442, and the material picking module 444 is installed on the output end of the transverse mechanism 443. The lifting mechanism 442 drives the transverse mechanism 443 and the material picking module 444 to do lifting and lowering movements, and the transverse mechanism 443 drives the material picking module 444 to do horizontal movement. The material picking module 444 transfers the mobile phone in the first carrier 42 to the second carrier 43. Specifically, when the material picking module 444 transfers the mobile phone to the second carrier 43, the mobile phone is first tilted up and down, and then one side of the mobile phone is pressed against the inner side wall of the second carrier 43, and finally the mobile phone is pivoted around the inner side wall, so that the mobile phone is placed in the second carrier 43.

[0039] See also Fig. 9 as well as Fig.11 , the material taking module 444 includes a first fixed seat 4441, a second fixed seat 4442, a pivot 4443 that penetrates the first fixed seat 4441 and the second fixed seat 4442 at the same time, a pressing assembly 4445 installed on the first fixed seat 4441, and a clamping assembly 4446 installed at the bottom of the second fixed seat 4442. It can be understood that the clamping assembly 4446 is used to clamp the mobile phone. The pivot 4443 is arranged horizontally, and the pressing assembly 4445 drives the second fixed seat 4442 to pivot relative to the first fixed seat 4441 around the pivot 4443 to switch between an inclined position and a straightened position. For example, when the second fixed seat 4442 is in an inclined position, the clamping assembly 4446 is inclined relative to the horizontal plane, so that the mobile phone is inclined relative to the horizontal plane; when the second fixed seat 4442 is in a straightened position, the clamping assembly 4446 is arranged horizontally, so that the mobile phone is arranged horizontally. Preferably, the material taking module 444 further includes a pressing assembly 4447, and the pressing assembly 4447 is located below the clamping assembly 4446. Specifically, the clamping assembly 4446 includes a clamping cylinder 44461 and two clamping plates 44462 connected to the clamping cylinder 44461, and the pressing assembly 4447 includes a pressing cylinder 44471 and a pressing plate 44472 connected to the pressing cylinder 44471, and the clamping plates 44462 are located on both sides of the pressing plate 44472. The clamping cylinder 44461 drives the clamping plates 44462 to move toward or away from each other to clamp or release the mobile phone. When the clamping plates 44462 release the mobile phone, the pressing cylinder 44471 drives the pressing plates 44472 to move downward to press the mobile phone into the second carrier 43.

[0040] Please continue reading Fig. 9 as well as Fig.11, the pressing assembly 4445 includes a pressing cylinder 44451, a pressing member 44452, a first connecting block 44453 and a tension spring 44454. The pressing member 44452 and the first connecting block 44453 are both connected to the output end of the pressing cylinder 44451, and the pressing cylinder 44451 drives the pressing member 44452 and the first connecting block 44453 to perform lifting motion together. The second fixed seat 4442 is provided with a second connecting block 44455, and the first connecting block 44453 and the second connecting block 44455 are connected by a tension spring 44454. Specifically, the first connecting block 44453, the second connecting block 44455 and the pressing member 44452 are arranged on the same side, that is, the first connecting block 44453, the second connecting block 44455 and the pressing member 44452 are located on the left or right side at the same time. When the pressure cylinder 44451 drives the pressure piece 44452 and the first connecting block 44453 to rise, the tension spring 44454 pulls the second connecting block 44455 to drive the second fixed seat 4442 to pivot upward around the pivot 4443, so that the clamping assembly 4446 drives the mobile phone to a tilted position; when the pressure cylinder 44451 drives the pressure piece 44452 to descend, the pressure piece 44452 presses the second fixed seat 4442 downward to restore the second fixed seat 4442 to the straightened position, so that the clamping assembly 4446 drives the mobile phone to a horizontal position.

[0041] In summary, the working process of the test device 4 is as follows: the material picking module 444 reaches the position of the first carrier 42 under the drive of the lifting mechanism 442 and the lateral movement mechanism 443, and after the clamping assembly 4446 of the material picking module 444 clamps the mobile phone on the first carrier 42, it reaches the top of the second carrier 43 under the action of the lifting mechanism 442 and the lateral movement mechanism 443. Before releasing the mobile phone, the pressing assembly 4445 drives the second fixed seat 4442 to rotate around the pivot 4443 to tilt the mobile phone, the lifting mechanism 442 descends, so that the lowest side of the mobile phone presses against the inner wall of the second carrier 43, and the pressing assembly 4445 drives the second fixed seat 4442 to rotate around the pivot 4443 to make the mobile phone horizontal, so that the mobile phone is assembled on the second carrier 43 through rotation, and then the material picking module 444 leaves the second carrier 43. Then, the driving device 45 drives the second carrier 43 to enter the opening 46 to allow the mobile phone to enter the box 41, and the test assembly tests the mobile phone. After the test is completed, the driving device 45 drives the second carrier 43 out of the box 41. Finally, the transfer device 5 transfers the mobile phone that has completed the test.

[0042] See also Fig.13 and Fig.15The synchronous pick-and-place device 52 further includes a spacing adjustment mechanism 523 for adjusting the spacing between the first pick-and-place unit 522a and the second pick-and-place unit 522b and a rotation adjustment mechanism 524 for rotating the first pick-and-place unit 522a. The spacing adjustment mechanism 523 and the rotation adjustment mechanism 524 are both disposed on the substrate 521. Specifically, in this embodiment, the second pick-and-place unit 522b is connected to the output end of the spacing adjustment mechanism 523, and the first pick-and-place unit 522a is connected to the output end of the rotation adjustment mechanism 524.

[0043] Please continue reading Figures 13 to 15 The spacing adjustment mechanism 523 includes a telescopic cylinder 5231 and a first connecting arm 5232 connected to the output end of the telescopic cylinder 5231. The telescopic cylinder 5231 is installed on the back of the substrate 521. The first connecting arm 5232 and the substrate 521 are perpendicular to each other. The second pick-and-place unit 522b is fixedly connected to the first connecting arm 5232. When the spacing adjustment mechanism 523 is working, the telescopic cylinder 5231 drives the first connecting arm 5232 to move in the horizontal direction away from or close to the first pick-and-place unit 522a, so that the distance between the two pick-and-place units 522 can be adjusted, which is conducive to adapting to the required spacing distance between the two pick-and-place units 522 at the conveying device 3 and the testing device 4, thereby avoiding interference and unreliable pick-and-place.

[0044] Please continue reading Figures 13 to 15 The rotation adjustment mechanism 524 includes a second connecting arm 5241 and a rotating cylinder 5242 installed on the end of the second connecting arm 5241. The second connecting arm 5241 is perpendicular to the base plate 521, and the second connecting arm 5241 is also parallel to the first connecting arm 5232. Specifically, the output end of the rotating cylinder 5242 is connected to the first pick-and-place unit 522a through a connecting plate 5243. The connecting plate 5243 and the first mounting plate 5221 (mentioned below) of the first pick-and-place unit 522a are spaced apart from each other in the up-down direction, and the connecting plate 5243 and the first mounting plate 5221 are connected by a vertically arranged column 5244. When the rotation adjustment mechanism 524 is working, the rotating cylinder 5242 drives the connecting plate 5243 to rotate, thereby driving the entire first pick-and-place unit 522a to rotate in the horizontal plane. When the mobile phone on the conveyor line is placed upside down, the first pick-and-place unit 522a is driven by the rotation adjustment mechanism 524 to rotate 180° in the horizontal direction before clamping the mobile phone, which is convenient for the subsequent inspection process. It is worth noting that the conveyor device 3 is provided with a visual inspection mechanism 6 to detect whether the mobile phone on the conveying surface 31 is placed correctly.

[0045] See also Figures 13 to 15The pick-and-place unit 522 includes a first mounting plate 5221, a second mounting plate 5222, a suction cup 5223, and a clamping mechanism 5224. The first mounting plate 5221 and the second mounting plate 5222 are arranged horizontally and spaced apart from each other in the up-down direction, and the second mounting plate 5222 is located below the first mounting plate 5221. The second mounting plate 5222 is provided with a hollow hole 52221, and the suction cup 5223 is vertically arranged and connected to the first mounting plate 5221, and the suction cup 5223 is also downwardly inserted into the hollow hole 52221. With the arrangement of the suction cup 5223, it is helpful to save space in the vertical direction and improve space utilization. The clamping mechanism 5224 includes a driver 52242 and four clamping claws 52241. The driver 52242 is installed on the first mounting plate 5221, and the clamping claws 52241 are movably arranged around the second mounting plate 5222. The driver 52242 links all the clamping claws 52241 to move toward or away from each other synchronously. It is worth noting that the suction cup 5223 is used to absorb the mobile phone, and the clamping mechanism 5224 is used to adjust the position accuracy of the mobile phone after the mobile phone is absorbed. For example, when the pick-up and placement unit 522 approaches the mobile phone, the suction cup 5223 absorbs the mobile phone, but because the mobile phone itself has a deviation in the placement angle, the mobile phone still has an angle deviation after being absorbed. With the help of the clamping mechanism 5224, after the mobile phone is absorbed, the clamping claws 52241 move toward each other synchronously, and correct the position of the mobile phone while clamping the mobile phone, so that the pick-up and placement unit 522 can clamp the mobile phone stably and reliably, and can also improve the position accuracy of the mobile phone after being clamped, which is beneficial to the subsequent processing or operation of the mobile phone. Specifically, in this embodiment, the clamping jaws 52241 are plate-shaped structures. When all the clamping jaws 52241 move toward each other synchronously, the inner side of the clamping jaws 52241 contacts the outer side of the mobile phone to clamp and adjust the mobile phone; when all the clamping jaws 52241 move away from each other synchronously, the clamping jaws 52241 release the mobile phone. Of course, in other embodiments, the suction cup 5223 can be connected to the second mounting plate 5222, but it is not limited thereto.

[0046] See also Figures 13 to 15 , a support column 5225 is provided between the first mounting plate 5221 and the second mounting plate 5222, and the support column 5225 is vertically arranged around the first mounting plate 5221, and the first mounting plate 5221 and the second mounting plate 5222 are spaced apart from each other in the up-down direction by means of the support column 5225, and the first mounting plate 5221 and the second mounting plate 5222 are relatively fixed. Preferably, an elastic member 52251 is also sleeved on the support column 5225. For example, the elastic member 52251 is a spring, but the present invention is not limited thereto.

[0047] See also Figure 5 and Figure 6The driver 52242 includes a lifting cylinder 522421 and a piston rod 522422 partially built into the lifting cylinder 522421. The piston rod 522422 is vertically arranged and downwardly inserted into the hollow hole 52221. The piston rod 522422 moves in the up-down direction. The up-down movement of the piston rod 522422 links all the clamping jaws 52241 to move toward or away from each other in the horizontal direction. Specifically, the clamping mechanism 5224 also includes a linkage block 52243 and a linkage column 52244. The linkage block 52243 is fixedly connected to the piston rod 522422, the linkage column 52244 is fixedly connected to the clamping jaw 52241, and the linkage column 52244 is movably connected to the linkage block 52243. Therefore, when the lifting cylinder 522421 drives the piston rod 522422 to move in the up-down direction, the linkage block 52243 moves up and down together with the piston rod 522422, thereby linking the movement of the linkage column 52244, and the movement of the linkage column 52244 drives all the clamping jaws 52241 to move toward or away from each other in the horizontal direction. Specifically, in this embodiment, the number of linkage blocks 52243 and linkage columns 52244 is consistent with the number of clamping jaws 52241 and corresponds one to one, that is, the number of linkage blocks 52243, linkage columns 52244 and clamping jaws 52241 is four respectively. The piston rod 522422 drives all linkage blocks 52243 to move up and down together, so as to link all linkage columns 52244 to move synchronously. It can be understood that all linkage blocks 52243 are fixedly connected to the piston rod 522422. The piston rod 522422 and the linkage block 52243 move up and down in the hollow hole 52221. With the help of the arrangement of the structure, the space of the pick-and-place unit 522 is reasonably used. Preferably, in this embodiment, all the linkage blocks 52243 are an integrated structure, but not limited to this. More specifically, in this embodiment, the integrated structure composed of all the linkage blocks 52243 is a cross-plate structure.

[0048] Please continue reading Fig.16 and Fig.17 , the linkage block 52243 is provided with a long slot 522431, and the linkage column 52244 is inserted into the long slot 522431 and slides along the long slot 522431. All the long slots 522431 are inclined and gradually expand outward from top to bottom with the piston rod 522422 as the center. Therefore, when the piston rod 522422 drives all the linkage blocks 52243 to descend, the linkage column 52244 moves horizontally from outside to inside, thereby driving all the clamping jaws 52241 to move horizontally in opposite directions. At this time, the clamping jaws 52241 are in a clamped state, such as Fig.16 As shown; when the piston rod 522422 drives all the linkage blocks 52243 to rise, the linkage column 52244 moves horizontally from the inside to the outside, thereby driving all the clamping jaws 52241 to move horizontally in opposite directions. At this time, the clamping jaws 52241 are in a released state, as shown in FIG. Fig.17shown.

[0049] See also Fig.15 The linkage column 52244 is inserted into the long slot 522431, and both ends thereof extend out of the long slot 522431, and each end is vertically connected to a connection column 5226, and the connection column 5226 is horizontally arranged, and the connection column 5226 also passes through the side wall of the second mounting plate 5222 and is connected to the clamping claw 52241. Therefore, when the linkage column 52244 moves horizontally toward or away from each other, the connection column 5226 drives the clamping claw 52241 to move telescopically.

[0050] In conjunction with the accompanying drawings, the working principle of the mobile phone function automatic test line 100 of the present invention is explained: the mobile phone to be tested is transferred to the to-be-tested area 3a of the conveying surface 31 of the conveying device 3 in an orderly manner through the loading mechanism 2, the robot 51 drives the synchronous pick-and-place device 52 to move to the top of the conveying surface 31, the first pick-and-place unit 522a clamps the mobile phone located in the to-be-tested area 3a, the robot 51 then drives the synchronous pick-and-place device 52 to move to the side of the testing device 4, the first pick-and-place unit 522a releases the mobile phone on the first carrier 42; at this time, the transfer device 5 and the testing device 4 simultaneously perform the following process, the testing device 4 transfers the mobile phone located on the first carrier 42 to the second carrier 43, the mobile phone and the second carrier 43 enter the box 41 together, and the testing assembly tests the mobile phone; the transfer device 5 returns to the top of the conveying device 3 again, clamps the to-be-tested mobile phone to another first carrier 42, and repeats the clamping of mobile phones until the four first carriers 42 are filled. After the first test of the mobile phone is completed, the second carrier 43 exits the box 41, and the first pick-and-place unit 522a of the robot 51 releases the mobile phone to be tested to the first carrier 42, and the second pick-and-place unit 522b clamps the tested mobile phone on the second carrier 43 and returns to the conveying surface 31. At this time, the second pick-and-place unit 522b releases the tested mobile phone to the tested area 3b, and the first pick-and-place unit 522a clamps the mobile phone on the to-be-tested area 3a. The transfer device 5 repeats the above actions continuously.

[0051] Compared with the prior art, the automatic mobile phone function test line 100 of the present invention relies on the coordination between the conveying device 3, the testing device 4 and the transfer device 5. Since the transfer device 5 includes a robot 51 and a synchronous pick-and-place device 52, and the synchronous pick-and-place device 52 includes two pick-and-place units 522 that perform opposite actions (clamping and releasing), when the synchronous pick-and-place device 52 is located above the conveying device 3, the pick-and-place unit 522 of one of them clamps the mobile phone located in the to-be-tested area 3a, and the pick-and-place unit 522 of the other one releases the mobile phone that has passed the test to the tested area 3b; when the synchronous pick-and-place device 52 is located beside the testing device 4, the pick-and-place unit 522 of one of them clamps the mobile phone located in the test station 4b, and the pick-and-place unit 522 of the other one releases the mobile phone to the pre-stored station 4a, so that the transfer device 5 has the functions of clamping and releasing synchronously, thereby reducing the waiting time of the mobile phone, improving the efficiency of the transfer, and thus improving the working efficiency of the automatic mobile phone function test line 100 of the present invention. In addition, since the synchronous pick-and-place device 52 includes two pick-and-place units 522, the cost is effectively reduced while completing two actions.

[0052] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
