Description

Technical Field

[0001] The present invention relates to mobile phone manufacturing, in particular to an assembling device for loading a SIM card for testing into a SIM card tray. Background Art

[0002] With the development trend of smart and thin mobile phones, mobile phones are required to be not only small and light, but also touch-sensitive, clear display and rich functions. In particular, to meet the growing demand for intelligence, people's requirements for mobile phone quality are becoming increasingly higher. Therefore, the requirements for mobile phone assembly accuracy and assembly efficiency are also becoming increasingly higher. After assembly is completed, in order to ensure the production quality of the mobile phone, it is necessary to test the various functions of the mobile phone. This involves verifying whether the SIM card tray is properly assembled using a test SIM card. Only when the SIM card tray is properly assembled in the card tray slot can the mobile phone motherboard effectively read the SIM card placed in the SIM card tray, thereby realizing the testing of various functions of the mobile phone. Therefore, it also involves the assembly operation of loading the test SIM card into the SIM card tray.

[0003] Currently, to efficiently verify that the assembly of SIM card trays in mass-produced mobile phones meets processing requirements, manual spot checks are often used. This makes it impossible to effectively test every mobile phone, resulting in quality risks. Furthermore, during testing, the test SIM card is often manually loaded into the SIM card tray and then the SIM card tray is returned to the mobile phone's card slot to complete the corresponding test. Manual card installation is time-consuming, relatively inefficient, and has correspondingly high labor costs. Furthermore, it is often impossible to efficiently and accurately assemble two SIM cards into the corresponding dual-SIM card trays. Existing assembly equipment often cannot simultaneously meet the card removal and loading operations of both single-card and dual-card SIM card trays, resulting in insufficient adaptability.

[0004] Therefore, there is an urgent need for an assembly device that can achieve accurate loading, has a simple structure and is efficient to overcome the above problems. Summary of the Invention

[0011] Preferably, a positioning block is installed at the top side end of the second connecting plate, and the positioning block has a strip groove arranged along its length direction, the output end of the swing cylinder is connected to a U-shaped block, and the positioning block is rotatably connected between the two side walls of the U-shaped block through a pivot shaft passing through its strip groove; the facing ends of the first connecting plate and the second connecting plate are correspondingly provided with two U-shaped blocks arranged facing each other, and the two U-shaped blocks arranged facing each other are socketed and rotatably connected by a pivot shaft passing through the side walls of the two U-shaped blocks.

In addition, since the driving mechanism can drive the suction cup and the push block to swing and move up and down, for a SIM card tray without an elastic card connector, when it is a single-card tray and the SIM card is loaded on the opposite front of the SIM card tray, it is only necessary to place the clamped SIM card tray in the card tray slot of the card tray carrier, and then use the suction cup to load the SIM card in the placement slot of the card tray carrier onto the SIM card tray. When the SIM card tray is a single-card tray, the SIM card holder can be easily inserted into the SIM card tray. When the SIM card tray is on the opposite back side of the SIM card tray, the clamping claws only need to vertically snap the clamped SIM card tray onto the SIM card placed in the card tray slot to achieve loading, and the suction cup does not need to move at this time; for the SIM card tray with an elastic snap-in part, when it is a single-card tray and the SIM card is loaded on the opposite front side of the SIM card tray, after the clamping claws place the clamped SIM card tray into the card tray slot of the card tray carrier, the suction cup can be swung to push the sucked SIM card obliquely onto the SIM card tray until the obliquely inserted SIM card is buckled to a horizontal snap-in position. The SIM card tray can be loaded into the SIM card tray; and when the SIM card tray is a dual-card tray, no matter whether the front side is provided with an elastic snap-in piece, the clamping claw can realize the snap connection with the SIM card on the back side during the placement of the SIM card tray, and the SIM card on the front side can be tilted and snap-connected by the suction cup. The assembly device of the present invention has a simple overall structure, a compact and reasonable layout, and is not only suitable for the automatic loading of the corresponding SIM card in a single-card or dual-card SIM card tray, but also suitable for the automatic loading of the corresponding SIM card in a SIM card tray with an elastic snap-in piece.

[0029] To make the technical contents, structural features, achieved purposes and effects of the present application clear, the following will be described in detail in combination with the embodiments and the accompanying drawings.

[0030] Reference Figures 1 to 7The present invention provides an assembly device 100 for loading a test SIM card 300 into a SIM card tray 200. The SIM card tray 200 can be a single-card tray that only carries a single SIM card 300, or a dual-card tray that can carry two SIM cards 300. The SIM card tray 200 for carrying two SIM cards 300 has a double-layer structure, with a card slot 201 and a card slot 202 for placing the SIM card 300 correspondingly provided on its front and back sides. The card slots 201 and 202 are connected at their relative centers. In addition, an elastic snap-fitting member 203 for fixing the SIM card 300 is provided at the side end of the card slot 201 on the front side. The SIM card on the back side can be directly snapped into the card slot 202 by shape restriction, while the SIM card on the front side requires the elastic snap-fitting member 203 to snap into place in the card slot 201. It should be noted that, in the present application, the SIM card tray 200 is placed on the feed tray 400 and is assembled with the SIM card on the card tray carrier 500. The card tray carrier 500 has a card tray slot 501 for placing the SIM card tray 200 and a placement slot 502 for placing the SIM card 300 for testing. The placement slot 502 is specifically located next to the positioning slot 501, and there can be multiple placement slots. The specifications and models of the SIM cards placed in the multiple placement slots 502 may be different.

[0031] In general, the assembly device 100 disclosed in the preferred embodiment of the present invention includes a four-axis robot 10, a clamping cylinder 20 and a driving mechanism 30 connected to the front and rear opposite sides of the four-axis robot 10, a clamping claw 40 connected to the output end of the clamping cylinder 20, and a suction cup 50 and a push block 60 spaced apart and connected to the output end of the driving mechanism 30. The four-axis robot 10 is used to drive the clamping claw 40, the suction cup 50 and the push block 60 to reciprocate between the feed tray 400 and the card tray carrier 500, the clamping cylinder 20 is used to drive the clamping claw 40 to clamp the SIM card tray 200 on the feed tray 400 and place it vertically in the card tray slot 501 of the card tray carrier 500 or vertically buckle it onto the SIM card 300 placed in the card tray slot 501, and the driving mechanism 30 is used to drive the suction cup 50 and the push block 60 to swing The suction cup 50 is configured to move vertically and vertically, allowing the suction cup 50 to absorb the SIM card 300 placed in the receiving slot 502 of the card tray carrier 500 and push it obliquely onto the SIM card tray 200 located in the card tray slot 501, until the obliquely inserted SIM card 300 is pressed into a horizontal position and engaged with the SIM card tray 200. The push block 60 is configured to abut the SIM card 300 from the side of the suction cup 50 to prevent the SIM card 300 from shifting during the placement process. The output end of the four-axis robot 10 is provided with a mounting frame 11, which is specifically L-shaped. The clamping cylinder 20 is mounted on the opposite front side of the mounting frame 11, and the drive mechanism 30 is mounted on the opposite rear side of the mounting frame 11.

[0032] See Figure 6 and Figure 7 In some embodiments, the assembly device 100 of the present invention further includes a first industrial camera 70, a second industrial camera 80, and a third industrial camera 90. The first industrial camera 70 is arranged above the feed tray 400 and is used to identify the position coordinates of the SIM card tray 200 in the feed tray 400 from the top. The second industrial camera 80 is arranged above the tray carrier 500 and is used to identify the position coordinates of the tray slot 501 of the tray carrier 500, the position coordinates of the SIM card tray 200 in the tray slot 501, or the position coordinates of the SIM card 300 in the tray slot 501 from the top. The third industrial camera 90 is arranged between the four-axis robot 10 and the tray carrier 500 and is used to identify the position coordinates of the SIM card tray 200 gripped by the gripper 40 from the bottom.

[0033] It should be noted that the assembly device 100 of the present invention further includes a controller, which is connected to the four-axis robot 10, the clamping cylinder 20, the drive mechanism 30, the first industrial camera 70, the second industrial camera 80, and the third industrial camera 90, respectively, to control the coordinated movements of these components. Specifically, the first industrial camera 70 identifies the position coordinates of the SIM card tray 200 in the feed tray 400 and transmits this identification information to the controller, which in turn issues instructions to adjust the motion trajectory of the four-axis robot so that the gripper 40 accurately positions and grips the SIM card tray 200. The second industrial camera 80 identifies the position coordinates of the card tray slot 501 of the card tray carrier 500 or the position coordinates of the SIM card 300 in the placement slot 501, and transmits this identification information to the controller. Combined with the third industrial camera 90, the controller identifies the position coordinates of the SIM card tray 200 gripped by the gripper 40 and transmits this identification information to the controller. The controller then compares the two identification information and issues instructions to adjust the movement angle of the gripper 40, thereby achieving accurate placement and fastening operations. The second industrial camera 80 identifies the position coordinates of the SIM card tray 200 in the tray slot 501, further facilitating accurate positioning and installation of the suction cup 50. The controller is an existing controller, and its structure and control principles are well known in the art, so a detailed description thereof will not be given here.

[0034] See Figure 9 and Figure 10The clamping jaws 40 include two clamping heads 41, which are symmetrically connected to the output ends of the clamping cylinder 20 in the left-right direction. Driven by the clamping cylinder 20, these clamping heads 41 move toward or away from each other in the left-right direction, thereby clamping or releasing the SIM card tray 200 located between them. Specifically, the clamping heads 41 are of a certain length and are arranged to be wider at the top and narrower at the bottom, facilitating pick-and-place operations in a relatively small space. Furthermore, a stopper 42 is connected between the two clamping heads 41 at their respective centers to guide and limit the left-right movement of the two clamping heads 41. Among them, at least two guide rods 421 in a symmetrical arrangement can be set at the left and right ends of the limit block 42, and the clamps 41 on both sides can be placed on the guide rods 421 on the corresponding sides one by one, so that when the two clamps 41 move toward each other or back to back, they move smoothly under the guidance of the corresponding guide rods 421, and are limited in movement by the central square limit block 42, which can effectively prevent damage to the SIM card tray 200 and effectively maintain the clamping distance, which is convenient for recognition by the third industrial camera 90.

[0035] See Figure 10 and Figure 11 The suction cup 50 and the push block 60 have a first position higher than the clamping jaw 40 and a second position lower than the clamping jaw 40, and the push block 60 is higher than or flush with the suction cup 50 when in the first position, and is lower than or flush with the suction cup 50 when in the second position, thereby making it easier to press the SIM card 300 sucked by the suction cup 50.

[0036] See Figures 8 to 11 The driving mechanism 30 includes a first lifting cylinder 31, a first connecting plate 32, a swing cylinder 33 and a second connecting plate 34. The first lifting cylinder 31 is connected to the rear side of the mounting frame 11 of the four-axis robot 10. The first connecting plate 32 is connected to the output end of the first lifting cylinder 31. The swing cylinder 33 is installed at the top side end of the first connecting plate 32. The rear side end of the second connecting plate 34 is used to be rotatably connected to the first connecting plate 32. The top side end of the second connecting plate 34 is used to be rotatably connected to the output end of the swing cylinder 33. The suction cup 50 and the push block 60 are spaced apart in the left and right directions and are arranged at the front side end of the second connecting plate 34. The first lifting cylinder 31 is used to drive the swing cylinder 33 and the suction cup 50 and the push block 60 arranged on the second connecting plate 34 to move up and down. The swing cylinder 33 is used to drive the second connecting plate 34 to drive the suction cup 50 and the push block 60 to swing relative to the first connecting plate 32, so that the suction cup 50 and the push block 60 can switch between the first position and the second position, thereby realizing the oblique insertion loading of the front SIM card 300.

[0037] It should be noted that, during specific loading, the suction cup 50 first inserts the adsorbed SIM card 300 into the card slot 201 of the SIM card 300 at an angle toward the direction close to the elastic clip 203 to press the elastic clip 203 to compress it, and then gradually presses the rear side end of the SIM card 300 away from the elastic clip 203 into the card slot 201 as it swings, thereby loading the SIM card 300 horizontally in the card slot 201. Afterwards, the suction cup 50 moves in the opposite direction to reset, and the elastic clip 203 is reset accordingly under the action of the elastic force, thereby clamping and fixing the SIM card 300 in the card slot 201 of the SIM card 300.

[0038] See Figures 10 to 12 Specifically, a positioning block 341 is mounted on the top side of the second connecting plate 34, and the positioning block 341 has a strip groove 3411 arranged along its length. The output end of the oscillating cylinder 33 is connected to a U-shaped block 331. The positioning block 341 is rotatably connected between the two side walls of the U-shaped block 331 via a pivot shaft 35 inserted through its strip groove 3411. Specifically, the strip groove 3411 is a straight groove or an oblique groove. The output end of the oscillating cylinder 33 is connected to the center of the bottom wall of the U-shaped block 331. Through holes for the pivot shaft 35 to pass through are respectively provided at opposite positions on the two side walls of the U-shaped block 331. Specifically, U-shaped blocks 321 and 342 are respectively provided at the facing ends of the first connecting plate 32 and the second connecting plate 34. The U-shaped blocks 321 and 342 are arranged in a socketed manner and are rotatably connected by a pivot shaft 35 inserted through their side walls. Under the action of the push and pull force in the front-to-back direction applied by the swing cylinder 33, the positioning block 341 rotates around the pivot shaft 35 pivotally connected to the U-shaped block 331, thereby driving the second connecting plate 34 to rotate around the pivot shaft 35 between the first connecting plate 32 and the second connecting plate 34, and then driving the suction cup 50 and the push block 60 to swing slightly relative to the first connecting plate 32, so as to realize the oblique insertion loading of the SIM card 300 on the front.

[0039] See Figure 11 and Figure 12 To prevent the second connecting plate 34 from swinging too much, in some embodiments, upper and lower stoppers 36 and 37 are provided on opposite sides of either the first connecting plate 32 or the second connecting plate 34 to limit the swing angle of the second connecting plate 34. Alternatively, the upper stopper 36 may be provided on the upper end of one of the first connecting plate 32 and the second connecting plate 34, while the lower stopper 37 may be provided on the lower end of the other.

[0040] See Figure 9 and Figure 10In some embodiments, the driving mechanism 30 further includes a second lifting cylinder 38, which is arranged on the relatively left side of the front side end of the second connecting plate 34. The push block 60 is detachably connected to the output end of the second lifting cylinder 38, so that it can move up and down relative to the second connecting plate 34 under the drive of the second lifting cylinder 38, so that it can not only make way when the suction cup 50 absorbs the SIM card 300, making it easier for the suction cup 50 to take the card, but also play a role in pressing and positioning the sucked SIM card 300 during the process of the suction cup 50 transferring and oblique insertion loading, thereby effectively preventing the SIM card 300 from shifting.

[0041] See Figures 10 to 12 In some embodiments, the drive mechanism 30 further includes a floating assembly 39, which includes a linear guide 391, a sliding plate 392, and an elastic member 393. The linear guide 391 is mounted on the right side of the front end of the second connecting plate 34 and is arranged along the longitudinal direction of the second connecting plate 34. The sliding plate 392 is slidably mounted on the linear guide 391. The elastic member 393 is telescopically connected between the top end of the second connecting plate 394 and the sliding plate 392. The suction cup 50 is detachably connected to the bottom end of the sliding plate 392. Therefore, when the suction cup 50 moves downward too quickly under the drive of the second lifting cylinder 38, the sliding plate 392 can slide in the opposite direction on the second connecting plate 394, causing the elastic member 393 to be compressed. This conveniently and effectively converts rigid movement into flexible movement, effectively preventing damage to the suction cup 50 and the SIM card 300. The suction cup 50 is a vacuum suction cup.

[0042] See below Figures 1 to 12 , the working principle of the assembly device 100 of the present invention is described:

[0043] During operation, the four-axis robot 10 first moves the gripper 40 to the feed tray 400 where the SIM card tray 200 is placed. Then, the gripper 40, driven by the clamping cylinder 20, moves downward to grip the SIM card tray 200 on the feed tray 400. Driven by the four-axis robot 10, the gripper 40 moves the gripped SIM card tray 200 into the tray slot 501 of the tray carrier 500 or vertically fastens the gripper onto the SIM card 300 in the tray slot 501, thereby achieving loading of the SIM card on the reverse side.

[0044] Next, the suction cup 50 and the push block 60 are moved to above the placement slot 502 of the card tray carrier 500 by the four-axis robot 10. After the suction cup 50 is driven downward by the first lifting cylinder 31 and sucks the SIM card 300 in the placement slot 502, the push block 60 is driven downward by the second lifting cylinder 38 until it abuts against the rear end of the SIM card 300.

[0045] Finally, the suction cup 50 and the push block 60 are moved to the top of the card tray slot 501 of the card tray carrier 500 by the four-axis robot 10. The suction cup 50 pushes the sucked SIM card 300 obliquely into the SIM card tray 200 in the card tray slot 501 until the obliquely inserted SIM card 300 is buckled and horizontally engaged in the SIM card tray 200, thereby achieving relatively front-facing loading of the SIM card 300.

[0046] By repeating the above operations continuously, an automated production line operation of loading the test SIM card 300 into the SIM card tray 200 can be achieved.

[0047] Compared with the prior art, in the assembly device 100 of the present invention, the clamping cylinder 20 and the driving mechanism 30 are connected to the front and rear opposite sides of the four-axis robot 10, the clamping claw 40 is connected to the output end of the clamping cylinder 20, and the suction cup 50 and the push block 60 are connected to the output end of the driving mechanism 30 at intervals. The four-axis robot 10 with a small footprint and high control accuracy can drive the clamping claw 40, the suction cup 50 and the push block 60 to flexibly and accurately move back and forth between the feed tray 400 and the card tray carrier 500, thereby facilitating the clamping claw 40 to clamp and transfer the SIM card tray 200 on the feed tray 400, and facilitating the suction cup 50 to absorb and transfer the SIM card 300 for testing in the placement slot 502 of the card tray carrier 500, and when the suction cup 50 is During the process of taking, placing and transferring the SIM card 300, the SIM card 300 is supported from the side by the push block 60, which effectively prevents it from shifting during the process, thereby further ensuring the accuracy of loading. In addition, since the driving mechanism 10 can drive the suction cup 50 and the push block 60 to swing and move up and down, for the SIM card tray 200 without the elastic clamping member 203, when it is a single-card tray and the SIM card 300 is loaded on the relative front of the SIM card tray 200, the clamping claw 40 only needs to place the clamped SIM card tray 200 in the tray slot 501 of the tray carrier 500, and then use the suction cup 50 to load the SIM card 300 in the placement slot 502 of the tray carrier 500 onto the SIM card tray 200. When the SIM card 300 is loaded onto the SIM card tray 200, the clamping claw 40 can be used to place the clamped SIM card tray 200 in the tray slot 501 of the tray carrier 500, and then use the suction cup 50 to load the SIM card 300 in the placement slot 502 of the tray carrier 500 onto the SIM card tray 200. When the card tray 200 is a single-card tray and the SIM card 300 is loaded on the opposite back side of the SIM card tray 200, the clamping claw 40 only needs to vertically buckle the clamped SIM card tray 200 on the SIM card 300 placed in the card tray slot 501 to achieve loading, and the suction cup 50 does not need to move at this time; and for the SIM card tray 200 with an elastic clamping member 203, when it is a single-card tray and the SIM card 300 is loaded on the opposite front side of the SIM card tray 200, after the clamping claw 40 places the clamped SIM card tray 200 in the card tray slot 501 of the card tray carrier 500, the suction cup 50 can push the sucked SIM card 300 obliquely onto the SIM card tray 200 by swinging until the obliquely inserted SIM card 300 is inserted. 0 is buckled to a horizontal position and snapped into the SIM card tray 200 to achieve loading; and when the SIM card tray 200 is a dual-card tray, no matter whether the front side thereof is provided with an elastic snap-in component 203, the clamping claw 40 can be used to snap into the SIM card 300 on the back side during the placement of the SIM card tray 200, and the SIM card 300 on the front side can be tilted and snapped into place by the suction cup 50. The assembly device 100 of the present invention has a simple overall structure, a compact and reasonable layout, and is not only suitable for the automatic loading of the corresponding SIM card 300 in a single-card or dual-card SIM card tray 200, but also suitable for the automatic loading of the corresponding SIM card 300 in a SIM card tray 201 with an elastic snap-in component 203. It is more versatile, flexible to use and has high loading accuracy.

[0048] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention.
