Technical Field

[0001] The invention relates to an automation device, in particular to an automatic assembly device for a mobile phone motor for assembling patches on a frame of a mobile phone vibration motor. Background Art

[0002] The internal components of mobile phones are relatively delicate and fragile. In order to reduce the damage caused by the vibration motor of the mobile phone to the internal electrical components of the mobile phone during the vibration process, a frame is usually set outside the vibration motor of the mobile phone to reduce the vibration impact on other components inside the mobile phone. In order to increase the anti-vibration and anti-fall strength of the frame, some frames are also equipped with metal patches on the outside to play a reinforcing role, especially at the bends of the frame.

[0003] At present, there is no processing equipment that can automatically load, align, inspect and unload such frames and patches. The welding work needs to be done manually with a handheld welding gun and other positioning fixtures. Since the size of the frame and motor set in the mobile phone is very small, and the metal patch is thinner and smaller, manual work has problems such as uneven welding quality and unguaranteed welding accuracy. Moreover, this manual assembly method is inefficient and has high labor costs in the context of mass production.

[0038] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0039] like Figure 1 As shown, the present invention relates to a frame 200 disposed outside the vibration motor of a mobile phone. The frame 200 is L-shaped. By welding two frames 200 to form a closed rectangular frame structure, a surrounding frame is formed in the vibration direction of the mobile phone vibration motor to reduce the vibration impact on other components inside the mobile phone. In order to increase the anti-vibration and anti-fall strength of the frame, it is necessary to weld a metal patch 300 (hereinafter referred to as patch) on the frame 200. The patch 300 is rectangular and the welding position is as shown in FIG. Figure 1 At the positions of the four diagonals shown by w1.

[0040] See also Figure 2 and Figure 3 The present invention provides a mobile phone motor automatic assembly device 100 for Figure 1 The frame 200 and the patch 300 shown in the figure are welded together, and the frame 200 and the patch 300 can be automatically loaded, the two can be automatically welded and shaped, and the welding accuracy can be automatically detected and unloaded. The mobile phone motor automatic assembly equipment 100 includes a first turntable A and a second turntable B arranged side by side, a frame loading device C, a coding device D, a scanning device E, a transfer device F and a detection device G arranged in sequence on the circumference of the first turntable A along its transmission direction, and a first mounting device H, a patch loading device I, a second mounting device J, a first welding device K and a second welding device L arranged in sequence on the circumference of the second turntable B along its transmission direction.

[0041] The frame loading device C is used to transfer the frames 200 to be welded to the first turntable A in groups, and is also used to take the frames 200 welded with patches 300 from the first turntable A in groups. The coding device D and the scanning device E code and scan the frames 200 to be welded one by one, and the detection device G detects the welding accuracy between the patches 300 and the frames 200 one by one. The transfer device F is located between the first turntable A and the second turntable B, and is used to transfer the frames 200 to be welded and the frames 200 welded with patches 300 in groups between the first turntable A and the second turntable B. The first mounting device H, the second mounting device J and the patch loading device I cooperate to complete the mounting of patches 300 on a group of frames 200 in two times, and the first welding device K and the second welding device L complete the welding of a group of frames 200 and patches 300 in two times.

[0042] On the basis of the above-mentioned devices, the mobile phone motor automatic assembly equipment 100 of the present invention further includes a pre-positioning device M disposed between the frame feeding device C and the first turntable A, a transfer device N disposed between the pre-positioning device M and the first turntable A, and a shaping device Q disposed on the circumference of the second turntable B and arranged in sequence along its transmission direction at a position behind the second welding device L. The pre-positioning device M is used to perform preliminary alignment on the six frames 200 in a group transmitted by the frame feeding device C at one time, so that the transfer device N can transfer the six pre-aligned frames 200 to the first turntable A at one time. The shaping device Q is used to flatten and shape the frame 200 and the patch 300 welded together to maintain the flatness of the welding.

[0043] like Figure 3 As shown, a plurality of positioning jigs 10 are arranged equidistantly along the circumference of the first turntable A and the second turntable B, and each positioning jig 10 is provided with a plurality of accommodating grooves corresponding to the shape of the outer contour of the frame 200, and the plurality of accommodating grooves are arranged in a straight line. As the first turntable A rotates, the positioning jig 10 can successively pass through the frame feeding device C, the coding device D, the scanning device E, the transfer device F and the detection device G, and as the second turntable B rotates, the positioning jig 10 can successively pass through the transfer device F, the first mounting device H, the patch loading device I, the second mounting device J, the first welding device K, the second welding device L and the shaping device Q.

[0044] It should be noted that the mobile phone motor automatic assembly equipment 100 of the present invention also includes a control system (not shown in the figure), which is electrically connected to the above-mentioned devices and is used to control the coordinated actions between the devices. Among them, the control system is an existing control system, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0045] The following combination Figures 2 to 21 , the structure and working principle of each device of the mobile phone motor automatic assembly equipment 100 of the present invention are described in detail according to the working order:

[0046] First, see Figure 4 and Figure 5The frame loading device C includes a conveying mechanism 21, a loading rack 22, a discharging rack 23 and a pick-up rack 24 arranged in a straight line on the upper side of the conveying mechanism 21, a pick-up and placement robot 25 arranged on the upper side of the pick-up and placement rack 24, and a material tray 26 that can flow between the loading rack 22, the discharging rack 23 and the pick-up and placement rack 24, and the material tray 26 can also be stacked in the loading rack 22 and the discharging rack 23. Among them, the material tray 26 has a plurality of positions arranged in an array, the material tray 26 in the loading rack 22 is used to load the frame 200 to be welded, and the material tray 26 in the discharging rack 23 is used to load the frame 200 welded with the patch 300. The pick-and-place manipulator 25 includes two rows of loading jaws 251 for picking up and unloading materials and a transfer module 252 connected to the two rows of loading jaws 251. The two rows of loading jaws 251 can be synchronously reciprocated between the pick-and-place rack 24 and the pre-positioning device M under the drive of the transfer module 253 connected to the two rows, so as to realize the alternate picking and placing of the frames 200 before and after welding. Specifically, the number of the loading jaws 251 is 12, 6 in each row, and the pick-and-place manipulator 25 can realize the picking and placing of a group of 6 frames 200 at a time. In order to increase the capacity rate of the material tray 26 and facilitate the picking and placing of the loading jaws 251, the frames 200 are placed sideways in the middle position, and the loading jaws 251 can extend into the position from the notch of the position to clamp the frame 200.

[0047] like Figure 5 As shown, the conveying mechanism 21 includes a linear guide rail 211 and a bracket 212 slidably mounted on the linear guide rail 211. The bracket 212 can slide on the linear guide rail 211 under the drive of the linear driver 213, so as to move back and forth between the loading rack 22, the unloading rack 23 and the pick-up rack 24. The bracket 212 can also move linearly up and down relative to the linear guide rail 211 under the cooperation of the rotary driver 214, the gear 215 connected to the output shaft of the rotary driver 214, and the rack 216 meshing with the gear 215, so that the stacked trays 26 in the loading rack 22 can be taken and sent one by one from top to bottom and from front to back relative to the linear guide rail 211, and then pushed from bottom to top to the pick-up rack 24, and the trays 26 loaded with welded frames 200 in the pick-up rack 24 can also be moved from top to bottom and from back to front relative to the linear guide rail 211 and then pushed from bottom to top to the unloading rack 23. Preferably, the pick-up and place rack 24 has two positioning areas, so that two material trays 26 can be carried at a time, thereby reducing the moving stroke of the bracket 212, thereby improving the feeding efficiency. It should be noted that the driving assembly for realizing the up and down movement of the bracket 212 relative to the linear guide rail 211 is not limited to the gear rack structure listed in this embodiment. In the process of the conveying mechanism 21 picking up and feeding the material tray 26 between the racks, the loading rack 22, the unloading rack 23 and the pick-up and place rack 24 realize the clamping and release of the material tray 26 through the automatic extension and contraction of the corresponding limit members 27 arranged thereon.

[0048] See also Figures 6 to 8When the frame loading device C moves the frame 200 placed sideways to the pre-positioning device M, because the patch 300 needs to be welded on the top surface of the long side of the frame 200, in order to facilitate welding, the pre-positioning device M needs to rotate the frame 200 by 90° and place it horizontally. Of course, the frame 200 placed horizontally in the pre-positioning device M after welding also needs to be rotated 90° in the opposite direction so that the frame loading device C can unload the frame 200 placed sideways into the material tray 26. Specifically, the pre-positioning device M includes a positioning platform 31, a plurality of slots 31a arranged in a straight line on the positioning platform 31 for placing the frame 200, a first clamping plate 32 arranged on the upper side of the positioning platform 31 and capable of sliding up and down relative to the positioning platform 31, a second clamping plate 33 arranged on the lower side of the working platform and capable of moving forward and backward relative to the positioning platform 31, and a first pressing head 34, a second pressing head 35 and a third pressing head 36 arranged on the upper side, the lower side and the left side of each slot 31a. The first pressing head 34 can be fixed on the first clamping plate 32 , or can be formed by protruding from the side end of the first clamping plate 32 at the position corresponding to each clamping slot 31 a . The second pressing head 35 and the third pressing head 36 are arranged in linkage with the second clamping plate 33 .

[0049] More specifically, the positioning platform 31 is provided with a plurality of positioning seats 311 arranged in a straight line, and each positioning seat 311 is provided with a corresponding slot 31a. The second pressure head 35 and the third pressure head 36 are movably arranged in the positioning seat 311, and are arranged in linkage with the second clamping plate 33 through the connection block 331, the elastic member 351, and the elastic member 362 arranged in the positioning seat 311. The positioning seat 311 has a positioning piece 312 and two positioning blocks 313 arranged parallel to and spaced from the positioning piece 312 on the left side. The short side of the frame 200 is inserted between the positioning piece 312 and the two positioning blocks 313, and a channel 31b is formed between the two positioning blocks 312 for the third pressure head 36 to move straightly left and right. The head and tail ends of the connection block 331 are respectively connected to the second clamping plate 33 and the second pressure head 35, and the third pressure head 36 is slidably abutted against the side wall of the connection block 331, and the abutting surfaces of the two are arc surfaces. Among them, the side wall of the connecting block 331 is wide at the top and narrow at the bottom and has a certain curvature to form an arc-shaped abutment surface 3311. Correspondingly, the semicircular end of the third pressure head 36 forms an arc-shaped abutment surface 361. The elastic member 351 is arranged between the connecting block 331 and the second pressure head 35, and the elastic member 362 is arranged between the third pressure head 36 and the positioning seat 311.

[0050] When the frame loading device C or the transfer device N moves a group of 6 frames 200 to be welded or welded to the 6 slots 31a of the pre-positioning device M, the second clamping plate 33 moves linearly under the drive of the clamping driver 39 connected thereto to approach or move away from the first clamping plate 32, so that the second pressing head 35 and the third pressing head 36, driven by the connecting block 331, respectively make linear movements close to the first pressing head 34, thereby cooperating with the first pressing head 34 to clamp the frame 200. Afterwards, the rotating driver 37 drives the positioning platform 31 connected thereto to rotate, thereby changing the placement direction of the frame 200. Finally, the yielding driver 38 drives the first clamping plate 32 connected thereto to slide to avoid, thereby facilitating the transfer device N or the frame loading device C to pick up and deliver the corresponding frame 200.

[0051] Please combine Figure 2 , Figure 3 , Figures 9 to 11 The transfer device N includes two rows of suction nozzles for picking up and unloading materials and a transfer module connected to the two rows of suction nozzles. The two rows of suction nozzles can be synchronously reciprocated between the pre-positioning device M and the first turntable A under the drive of the transfer module connected to the two, so as to realize the alternating picking and placing of the frame 200 before and after welding. Six positioning fixtures are evenly distributed on the first turntable A. The positioning fixture 10 includes a limiter 11 and a driving member 12. The limiter 11 is movably or / and rotatably arranged on the side or / and top side of the accommodating groove 10a. The driving member 12 is arranged on the side or lower side of the accommodating groove 10a in a manner of abutting or slidably abutting with the limiter 11, and is used to drive the limiter 11 to move or / and rotate to tighten or release the frame 200 placed in the accommodating groove 10a.

[0052] Specifically, the positioning fixture 10 also includes a bottom plate 13, a positioning block 14 fixed on the bottom plate 13, and a sliding block 15 slidably mounted on the bottom plate 13 and located beside the positioning block 14. The positioning block 14 is provided with a plurality of accommodating grooves 10a spaced apart along its longitudinal direction, and the limiting member 11 includes a first limiting member 111 and a second limiting member 112. A first limiting member 111 is fixedly mounted on the sliding block 15 at a position corresponding to each accommodating groove 10a. The first limiting member 111 can move along the longitudinal straight line of the positioning block 14 with the sliding block 15, thereby limiting the movement of the frame 200 in the front-rear direction from the side. A second limiting member 112 is pivotally connected to a position corresponding to each accommodating groove 10a on the positioning block 14. The second limiting member 112 can rotate relative to the positioning block 14, thereby limiting the movement of the frame 200 in the up-and-down direction from the top side.

[0053] More specifically, a first wedge block 151 protrudes from the lower end of the sliding block 15 and is located on the lower side of the bottom plate 13, a push rod 1121 protrudes from the lower end of the second limiting member 112 and is located on the lower side of the bottom plate 13, and the driving member 12 includes a first driver 121, a roller 122 connected to the output end of the first driver 121 and corresponding to the first wedge block 151, and a second wedge block 123 connected to the output end of the first driver 121 and corresponding to the push rod 1121. The first driver 121 can drive the roller 122 and the second wedge block 123 to move linearly up and down relative to the base plate 13, so that the roller 122 and the first wedge block 151 can be slidably abutted, so that the first limit member 111 is separated from or abutted against the short side of the frame 200 to release or restore the limit of the frame 200 in the front and rear directions, and at the same time, the second wedge block 123 and the push rod 1121 can be slidably abutted, so that the second limit member 112 is rotated to be separated from or abutted against the long side of the frame 200 to release or restore the limit of the frame 200 in the up and down directions.

[0054] When the transfer device N transfers a group of 6 frames 200 to be welded obtained from the pre-positioning device M to the positioning fixture 10 at the starting position of the first turntable A, when the frame 200 rotates with the positioning fixture 10 to the transfer device F at the transfer position, or when the positioning fixture 10 carrying the welded frame 200 rotates to the starting position near the transfer device N, the driving member 12 moves linearly upward, so that the limiting member 11 makes a linear movement relatively away from the accommodating groove 10a, thereby making way for loading or releasing the limitation of the corresponding frame 200 in the accommodating groove 10a to facilitate material transfer and unloading.

[0055] When the frame 200 to be welded is rotated to the coding device D and the scanning device E along with the positioning fixture 10, the coding device D is used to Figure 1 At the position shown by w2, a barcode, a QR code or other graphics and text with product information are laser engraved. The code scanning device E is used to scan and identify the information laser engraved on the frame 200, determine whether the laser engraving is wrong, and enter the correct information into the system to provide information for the subsequent detection of the detection device G. Preferably, a detection mechanism for identifying the position shown by w2 is provided at the coding device D. When the scanned frame 200 rotates on the first turntable A to the transfer device F, the transfer device F transfers a group of 6 frames 200 to the positioning fixture 10 at the starting position of the second turntable B.

[0056] See also Figure 12 to Figure 14, 6 positioning jigs are evenly distributed on the second turntable B. In the second turntable B, the limiting member 11 of the positioning jig 10 also includes a third limiting member 113. A third limiting member 113 is suspended above each receiving groove 10a on the positioning jig 10. The third limiting member 113 can rotate or move relative to the positioning block 14, and limit the movement of the frame 200 in the up and down directions from the top side again, or limit the relative movement between the frame 200 and the patch 300 mounted on the frame 200 from the top side. The third limiting member 113 and the second limiting member 112 are staggered. The third limiting member 113 specifically abuts the relative center of the patch 300, so that the welding positions w1 at the four corners of the patch 300 can be exposed, and the second limiting member 112 can specifically abut the position on the frame 200 that is relatively far away from the welding position w1.

[0057] Specifically, the lower end of the third limiting member 113 protrudes with a plug-in rod 1131 located on the lower side of the base plate 13. Correspondingly, the driving member 12 also includes a second driver 125, a third driver 126 connected to the output end of the second driver 125, and a plug-in block 124 connected to the output end of the third driver 126 and arranged corresponding to the plug-in rod 1131. The plug-in block 124 has a slot 124a corresponding to the end of the plug-in rod 1131. The second driver 125 is used to drive the plug-in block 124 to move linearly up and down, so that the plug-in rod 1131 is plugged into the slot 124a of the plug-in block 124. The third driver 126 then drives the plug-in block 124 to move linearly back and forth, so that the plug-in rod 1131 rotates under the limitation of the slot 124a, thereby making way for taking and releasing materials, or releasing or restoring the limitation of the frame 200 or the patch 300 in the up and down directions.

[0058] It should be noted that on the second turntable B, the limiting member 11 of each positioning fixture 10 includes a first limiting member 111, a second limiting member 112 and a third limiting member 113, and below the second turntable B, only at the corresponding transfer device F and the shaping device Q, the driving member 12 of the positioning fixture 10 includes a roller 122, a second wedge block 123, a plug-in block 124, a first driver 121, a second driver 125 and a third driver 126; and at the corresponding positions of the first mounting device H, the second mounting device J, the first welding device K and the second welding device L where the frame 200 does not need to be removed from the positioning fixture 10, the driving member 12 only needs to include a plug-in block 124, a second driver 125 and a third driver 126. Preferably, in order to simplify the structure, only three plug-in blocks 124 and corresponding drivers can be set at the first mounting device H, the second mounting device J, the first welding device K and the second welding device L.

[0059] See also Figures 15 to 17When the frame 200 to be welded rotates to the first mounting device H and the second mounting device J in sequence with the positioning fixture 10 on the second turntable B, the patch loading device I located at the symmetrical center of the two alternately transfers the patches 300 to the two. The patch loading device I includes a stamping mechanism 41, a material picking mechanism 42, and a pushing mechanism 43 and a pulling mechanism 44 arranged on the front and rear sides of the two. The pushing mechanism 43 pushes the material belt 400 so that the patches 300 arranged equidistantly on the material belt 400 pass through the stamping mechanism 41 and the material picking mechanism 42 one by one. The two picking heads 421 of the picking mechanism 42 move linearly in a direction perpendicular to the conveying direction of the material belt 400 under the drive of the picking driver 422, and move alternately to the bottom of the stamping mechanism 41, and can move up and down under the drive of the correspondingly connected pushing driver 423 to connect with the discharge end 411 of the stamping mechanism 41, so that the discharge end 411 receives the patch 300 punched out of the punching cut of the material belt 400, and transfers the patch 300 to the corresponding first mounting device H or the second mounting device J, and the pulling mechanism 44 is used to collect the material belt 400 after the patch 300 is punched out.

[0060] Specifically, the patch loading device I also includes a discharge tray 45, a receiving tray 46 and an alignment mechanism 47. The material strip 400 is attached to the base film 500 and rolled into a roll. The rolled material strip 400 is loaded on the discharge tray 45. The free end of the base film 500 is wound around the receiving tray 45. The receiving tray 45 is used for separating the material strip 400 from the base film 500 and for winding up the base film 500. The free end of the material strip 400 is wound around the alignment mechanism 47, the pushing mechanism 43, the punching mechanism 41 and the material taking mechanism 42 in sequence and then connected to the pulling mechanism 44. Since the material strip 400 and the bottom film 500 are separated in the air, in order to realize the horizontal transfer of the material strip 400, the alignment pin 471 of the alignment mechanism 47 can be inserted into the positioning hole 401 of the material strip 400 under the drive of the alignment driver 4711 to realize the preliminary position adjustment, so that the material strip 400 can move linearly in the strip guide groove. The push pin 431 of the push mechanism 43 moves up and down under the drive of the downward drive 4311 connected thereto and can be inserted into the positioning hole 401 of the material strip 400, and then moves forward and backward under the drive of the push driver 4312 connected thereto and can gradually push the material strip 400 toward the direction of the punching mechanism 41, so that the patch 300 on the material strip 400 is sequentially aligned with the position of the punch head of the punching mechanism 41; and the positioning pin 432 of the push mechanism 43 moves up and down under the drive of the positioning driver 4321 connected thereto, and positions the material strip 400 during punching. The material strip 400 from which the patch 300 is peeled off after punching is collected in a material receiving box under the action of the pulling driver 441 of the pulling mechanism 44 . The positioning hole 401 is located at the edge of at least one side of the material strip 400 .

[0061] See also Fig.18The first mounting device H and the second mounting device J have the same structure, both of which include a mounting robot 51 and a mounting head 52 connected to the output end of the mounting robot 51. The mounting robot 51 drives the mounting head 52 to absorb the patch 300 at the corresponding material pick-up head 421 and mount the patch 300 on the frame 200. The first mounting device H and the second mounting device J are respectively responsible for mounting the patches 300 on three frames 200 in a group of frames 200, thereby successively mounting the patches 300 on a group of frames 200 twice. In order to improve the accuracy of mounting, the first mounting device H and the second mounting device J are also provided with an image detection mechanism for detecting the fit between the patch 300 and the frame 200. Among them, the CCD camera 53 arranged at the top and the CCD camera 54 arranged at the side are used to identify the position coordinates of the frame 200, and the CCD camera 55 arranged at the bottom is used to identify the contour shape of the patch 300.

[0062] The mounted frame 200 is transferred to the first welding device K and the second welding device L. Both the first welding device K and the second welding device L are laser welding machines, which are respectively responsible for welding three frames 200 in a group of frames 200 and the patch 300, thereby realizing the welding of the patch 300 on a group of frames 200 in two times.

[0063] See also Figures 19 to 21 The frame 200 and patch 300 welded together are transferred through the shaping device Q. The shaping device Q includes a pick-up and delivery mechanism 71 disposed on the second turntable B, a carrier 72 disposed on the side of the second turntable B, and a pressing mechanism 73 located above the carrier 72 and movable up and down relative to the carrier 72. A plurality of positioning blocks 721 corresponding to the shape of the frame 200 are arranged in a straight line on the carrier 72. A clamping member 722 is disposed at the side end of each positioning block 721. The plurality of clamping members 722 are driven by a clamping driver 723. The carrier 72 can be moved to the position directly below the pressing mechanism 73 under the drive of the alignment driver 724. The plurality of suction heads 711 of the pick-up and delivery mechanism 71 are moved under the action of the downward drive 712 and the push drive 713, and the frame 200 and patch 300 welded together on the positioning fixture 10 can be transferred one by one to the positioning blocks 72 of the carrier 72 after alignment. 1; the pressing mechanism 73 has a pressing head 731 corresponding to the positioning block 721, and the pressing head 731 can move linearly up and down relative to the positioning block 721 under the drive of the pressing driver 732, so as to press the patch 300 and the frame 200 located therebetween; further, while maintaining the crimping state, either the pressing head 731 or the positioning block 721 can also move linearly back and forth relative to the other under the drive of the moving driver 725, so that the pressing head 731 repeatedly rolls on the patch 300 and the frame 200, thereby ensuring the flatness of the frame 200 and the patch 300 after welding.

[0064] The shaped frame 200 and patch 300 are returned to the first turntable A from the second turntable B via the transfer device F, and are sequentially transferred to the detection device G. The detection device G includes CCD, distance sensor and other related components arranged sequentially along the transfer direction of the first turntable A, which are used to measure the length, width and height of the welded frame 200 and patch 300, so as to detect the parallelism and flatness of the welding to determine whether the welding quality is qualified. The tested frame 200 is transferred from the starting position of the first turntable A to the pre-positioning device M by the transfer device N, and after turning, the frame loading device C takes the unloaded material from the pre-positioning device M.

The action is single and reliable, and the production line is effectively balanced. Moreover, the frame 200 to be welded and the welded frame 200 are grouped and alternately transferred between the frame feeding device C, the first turntable A, the transfer device F and the second turntable B, which effectively improves the assembly efficiency. The cooperation between the coding device D, the scanning device E and the detection device G effectively monitors the welding of each frame 200 and the patch 300, which is convenient for product quality control.
