It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0028] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0029] In the automated assembly production process of mobile phone hinges, assembly jigs are often used to carry and position the parts to be assembled, and cooperate with the production line to achieve efficient automated operation. In order to ensure that the assembly jig can be stably integrated into the assembly line and reliably transferred when reaching the corresponding station, a docking structure such as a positioning hole, a connecting buckle or a stop structure is usually provided on the jig to match the conveying mechanism, the transfer mechanism and the like. However, such structures for working with the assembly line often increase the overall size and structural complexity of the assembly jig.

[0030] On the one hand, the large structure size not only limits the flexible handling and operation of the assembly jig during transfer between stations; on the other hand, the increased docking structure also occupies the production line space, affecting the overall layout planning and equipment compactness.

[0031] Please refer to Figures 1 to 6 , the jig carrying device 100 provided by the embodiment of the present application will be described. The jig carrying device 100 is used to carry the assembly jig 200, and the jig carrying device 100 comprises a bottom plate 10 and a clamping assembly 20. The bottom plate 10 has a first surface 11 and a second surface 12 in the thickness direction. The clamping assembly 20 comprises at least two clamping pieces 21, which are arranged in the first surface 11 and are oppositely arranged. The area between the two clamping pieces 21 of the bottom plate 10 forms a placement area 111 for accommodating the assembly jig 200. The first surface 11 is provided with a positioning column 13 located in the placement area 111, which is used to cooperate with the positioning hole 210 of the assembly jig 200 to realize positioning.

[0032] The bottom plate 10 is the basic structure of the whole jig carrying device 100, the first surface 11 of which is used for integrating the clamping assembly 20 and the positioning column 13, etc., and the second surface 12 of which is used for connecting or cooperating with the conveying mechanism (such as a conveyor belt, a mechanical arm, a sliding table, etc.) on the automatic production line to realize the positioning, movement or fixing of the whole device in the production line.

[0033] The clamping assembly 20 is used for restraining the assembly jig 200 on both sides of the placement area 111 through two oppositely arranged clamping pieces 21 to prevent the assembly jig 200 from deviating, shaking or falling off during transportation or assembly. The clamping assembly 20 facilitates the quick placement and removal of the assembly jig 200, and improves the automation operation efficiency. The clamping assembly 20 can adjust the clamping distance or clamping mode according to different models of the assembly jig 200, and improves the versatility of the jig carrying device 100.

[0034] The clamping piece 21 can be a fixed stop block or a sliding clamping block, or can be an elastic clamping jaw or a magnetic clamping mechanism, and the specific structure can be selected according to the structure of the automatic production line, etc.

[0035] The placement area 111 is a placement area formed between the two clamping pieces 21 on the bottom plate 10. The size of the placement area 111 can be adapted to the bottom profile of the assembly jig 200. The installation position of the clamping piece 21 is adjusted to match different specifications of the assembly jig 200, and a stable placement area 111 of the assembly jig 200 is provided. In some embodiments, the placement area 111 is open from the top, which facilitates the vertical placement of the assembly jig 200 into the area by the automatic equipment (such as a mechanical arm). Figure 2

[0036] The positioning column 13 is a protruding structure arranged on the first surface 11 of the bottom plate 10 and located in the placement area 111, which is used for being inserted into the corresponding hole at the bottom of the assembly jig 200 to realize the precise positioning of the assembly jig 200 on the jig carrying device 100, and ensure the process consistency of the subsequent assembly station.

[0037] The positioning column 13 can be a cylindrical pin, a rhombic pin or a positioning column 13 with a guide chamfer, etc., and the positioning hole 210 cooperates with the positioning column 13.

[0038] ​The assembly jig 200 does not need to integrate a complex flow line docking structure, and only needs to have a basic positioning structure (such as positioning hole 210, etc.) to adapt to the jig carrying device 100, thereby simplifying the overall structure of the assembly jig 200. The relative spacing layout of the clamping piece 21 forms a stable geometric constraint area, so that the assembly jig 200 remains fixed in position during transmission, avoiding volume expansion caused by additional limiting features; the protruding position of the positioning column 13 accurately corresponds to the positioning hole 210 of the assembly jig 200, achieving rapid alignment, and the assembly jig 200 itself only needs simple hole structures and the like to meet the positioning requirements, without the need for built-in buckles 213 or stop mechanisms.

[0039] Through the jig carrying device 100, the flow line docking structure originally integrated on the assembly jig 200 body can be transferred to the independent jig carrying device 100, making the assembly jig 200 itself more simple in structure and smaller in size, facilitating flexible handling and operation between stations, at the same time, the space utilization rate of the production line layout is improved, and the compactness of the equipment is enhanced, effectively solving the problems of volume increase and complex structure caused by the assembly jig 200 integrating the flow line docking structure, significantly improving the compactness of the production line layout and the equipment integration.

[0040] In the automatic assembly operation, the assembly jig 200 of the mobile phone hinge is first taken out from the previous process or the stock bin, and is vertically lowered into the placement area 111 of the jig carrying device 100 through a mechanical arm or a conveying mechanism; at this time, the positioning hole 210 at the bottom of the assembly jig 200 will automatically align and fit with the positioning column 13 protruding on the first surface 11 of the bottom plate 10, achieving accurate positioning; at the same time, the two oppositely arranged clamping pieces 21 limit or elastically clamp the side edges of the assembly jig 200 horizontally, preventing it from shifting or falling off during subsequent conveying or assembly; then, the entire jig carrying device 100 together with the assembly jig 200 thereon is conveyed to the corresponding station, and the automatic assembly of the hinge parts is completed at the station; after the operation is completed, the clamping assembly 20 is released, and the assembly jig 200 is taken away, while the jig carrying device 100 can be used cyclically on the conveying mechanism of the production line.

[0041] Compared with the prior art, the jig bearing device 100 provided by the embodiments of the present application has the following advantages. The first surface 11 of the bottom plate 10 is provided with oppositely arranged clamping pieces 21 to form a placement area 111, and a positioning column 13 is protrudingly arranged in the placement area 111, so that the assembly jig 200 can be stably accommodated between the clamping pieces 21, and precise alignment is realized through cooperation of the positioning hole 210 of the assembly jig 200 and the positioning column 13. Therefore, through the jig bearing device 100, the pipeline docking structures originally integrated on the assembly jig 200 can be transferred to the independent jig bearing device 100, so that the body structure of the assembly jig 200 is simplified, the overall volume is reduced, the flexibility of carrying and operating between stations is improved, and the compactness of the production line layout is significantly improved.

[0042] In some embodiments of the present application, referring to Figure 2 、 Figure 5 and Figure 6 , the clamping piece 21 comprises a clamping seat 211, an elastic piece 212 and a buckle 213, the clamping seat 211 is fixedly connected to the first surface 11, the buckle 213 is used for clamping a side of the assembly jig 200 away from the first surface 11, the buckle 213 is rotatably connected to the clamping seat 211, and the elastic piece 212 is arranged between the clamping seat 211 and the buckle 213 and used for moving the clamping position of the buckle 213 towards the assembly jig 200.

[0043] The clamping seat 211 is a support structure for providing a stable mounting base to ensure that the position of the clamping piece 21 on the bottom plate 10 is accurate and not easy to deviate. The clamping seat 211 can specifically adopt a block structure or a bracket, and the material of the clamping seat 211 can be metal or high-strength plastic.

[0044] The buckle 213 is rotatably connected to the clamping seat 211, which can be achieved through a rotating shaft or other hinge mechanisms.

[0045] The elastic piece 212 is an elastic element for providing a reset elastic force, which can be achieved by using a torsion spring, a tension spring or an elastic rubber pad. The elastic piece 212 is connected between the clamping seat 211 and the buckle 213 to drive the clamping position (clamping end) of the buckle 213 to rotate towards the center of the placement area 111, so as to clamp the assembly jig 200.

[0046] The buckle 213 is used for clamping a side of the assembly jig 200 away from the first surface 11, so as to fix the assembly jig 200 on the bottom plate 10.

[0047] The clamping seat 211 is fixedly connected to the first surface 11 of the bottom plate 10, and provides an accurate and stable mounting position for the entire clamping mechanism. The buckle 213 is rotatably connected to the clamping seat 211, so that the buckle 213 can be flexibly rotated according to the placement process of the assembly jig 200. The elastic member 212 provides an elastic force to push the clamping position of the buckle 213 to move towards the assembly jig 200, guiding the natural alignment of the boss 220 with the buckle 213.

[0048] In some embodiments, the boss 220 is arranged on the side of the assembly jig 200 and used to cooperate with the buckle 213. The boss 220 is a positioning protrusion on the side of the assembly jig 200, which can adopt a cylindrical, square or hemispherical protrusion structure. The boss 220 is used to form a clamping locking relationship with the buckle 213, and ensures that the assembly jig 200 is reliably positioned.

[0049] The elastic member 212 is arranged between the clamping seat 211 and the buckle 213. When the assembly jig 200 is placed in the placement area 111, the boss 220 on the side of the assembly jig 200 pushes the buckle 213 to rotate and compresses the elastic member 212 to store elastic force. When the boss 220 reaches a predetermined position, the elastic member 212 releases the elastic force to drive the clamping position of the buckle 213 to automatically rotate towards the center of the placement area 111 and clamps with the boss 220, achieving automatic locking. Thus, the assembly jig 200 is firmly positioned in the placement area 111, effectively preventing vibration or inertial displacement during transmission, and forming a complete automatic clamping and resetting mechanism. The assembly jig 200 is automatically clamped and fixed during transmission, effectively suppressing displacement caused by vibration or movement, reducing manual intervention, and improving the automation efficiency and assembly precision of the production line.

[0050] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The clamping assembly 20 includes four clamping members 21, and the four clamping members 21 are arranged in pairs and form two spaced placement areas 111 on the first surface 11.

[0051] The four clamping members 21 refer to the number of clamping members 21 in the clamping assembly 20 being four. The specific structure of the clamping member 21 can adopt the same or similar structure as the above-described clamping member 21, that is, the combination including the clamping seat 211, the elastic member 212 and the buckle 213.

[0052] The four clamping members 21 are arranged in pairs on opposite sides of the first surface 11 of the bottom plate 10, that is, the clamping members 21 are arranged in pairs. Specifically, they can be distributed symmetrically along the transmission direction X or an axis perpendicular to the transmission direction X, to ensure that the clamping force is uniformly distributed and adapt to the positioning needs of assembly jigs 200 of different sizes.

[0053] Two independent placement areas 111 are formed on the first surface 11 of the base plate 10 by four clamping members 21. The spacing distance between the two placement areas 111 can be adjusted according to the size of the assembly jig 200 to simultaneously accommodate multiple assembly jigs 200 without interfering with each other, thereby improving the utilization efficiency of the surface space of the base plate 10.

[0054] Each placement area 111 is clamped and fixed by a pair of opposite clamping members 21, thereby uniformly distributing the clamping force during the conveying process and preventing the assembly jig 200 from shifting or falling due to vibration or external force. At the same time, the spacing between the two placement areas 111 ensures that adjacent assembly jigs 200 do not interfere with each other when being carried, maintaining the precise fit between the positioning column 13 and the positioning hole 210 of the assembly jig 200. This layout realizes the separation of the surface space of the base plate 10 without increasing the overall size of the base plate 10, thereby improving the space utilization. Each jig carrying device 100 can simultaneously carry two assembly jigs 200, reducing the number of devices deployed on the production line, saving production line space, and improving the compactness of the equipment and the continuity of the production process.

[0055] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The jig carrying device 100 further comprises a plurality of wear-resistant rings 31 arranged in the placement area 111, and the plurality of wear-resistant rings 31 are arranged at intervals on the first surface 11. The wear-resistant ring 31 is at least partially protruding from the first surface 11 and used to abut against the bottom surface of the assembly jig 200.

[0056] The wear-resistant ring 31 is a wear-resistant component for bearing frictional load. The wear-resistant ring 31 can be made of metal or high polymer material, etc. In some embodiments, the material of the wear-resistant ring 31 is steel, which has good strength and toughness, and also has high wear resistance.

[0057] The plurality of wear-resistant rings 31 are arranged in a dispersed manner on the first surface 11, which can be arranged at equal intervals or unevenly distributed according to the contour of the bottom surface of the assembly jig 200. In some embodiments, four wear-resistant rings 31 are arranged at the four corners of the placement area 111 to correspond to the four corners of the bottom surface of the assembly jig 200.

[0058] The wear-resistant ring 31 is at least partially protruding from the first surface 11, so that the top surface (end surface away from the first surface 11) of the wear-resistant ring 31 forms a lifting structure relative to the first surface 11. The protruding height of the wear-resistant ring 31 can be achieved by adjusting the embedding depth or selecting wear-resistant rings 31 of different height specifications. The top surface of the wear-resistant ring 31 forms a bearing surface 311, which can be a plane or a slightly convex curved surface, used to abut against the bottom surface of the assembly jig 200 to provide uniform contact pressure distribution.

[0059] By arranging multiple wear-resistant rings 31 in the placement area 111, part of the wear-resistant rings 31 protrude from the first surface 11; when the assembly jig 200 is placed in the placement area 111, the bottom surface is in contact with the wear-resistant ring 31, and the load is completely transferred to the wear-resistant ring 31, and the wear-resistant property of the wear-resistant ring 31 effectively resists repeated friction, thereby preventing the first surface 11 of the bottom plate 10 from being directly rubbed. Since the bottom plate 10 no longer directly bears the load and friction, the bottom plate 10 can be made of a material with lower density and lighter weight, such as aluminum alloy, high-strength engineering plastic, etc., which can greatly reduce the overall weight while ensuring structural rigidity, facilitate pipeline transportation, and reduce the load of the mechanical arm.

[0060] In some embodiments of the present application, please refer to Figure 1 、 Figure 3 and Figure 4 , the jig carrying device 100 further comprises a stop block 32, and the bottom plate 10 is provided with a stop groove 14 at each end along the conveying direction X of the bottom plate 10, and the stop block 32 is connected to the groove bottom of the stop groove 14.

[0061] As shown in Figure 3 , the conveying direction X of the bottom plate 10 refers to the main movement direction of the jig carrying device 100 when it is transported or moved on the automated assembly line. The stop groove 14 is machined inward along the conveying direction X of the bottom plate 10 at the end surface of each end of the bottom plate 10 along the conveying direction X.

[0062] The stop groove 14 can be designed as a rectangular groove, a U-shaped groove or a V-shaped groove, etc., to directly receive the impact force from the stopping mechanism on the assembly line, avoiding the impact force from being dispersed to other parts of the bottom plate 10. The opening of the stop groove 14 faces outward to cooperate with the stopping mechanism on the assembly line. The groove bottom of the stop groove 14 refers to the bottom support surface of the stop groove 14, which can be a flat surface or a curved surface, with the purpose of ensuring the stable connection of the stop block 32 and the uniform transmission of impact force, preventing the buffer from failing due to loose connection. The specific position, depth and size of the stop groove 14 can be designed according to the stopping mechanism of the assembly line.

[0063] The stop block 32 is installed on the groove bottom of the stop groove 14 to absorb and disperse impact energy, which can be made of elastic materials such as rubber and silicone, or high-strength engineering plastics.

[0064] The stop groove 14 precisely corresponds to the stopping mechanism on the conveying path, so that when the jig carrying device 100 is stopped and the assembly jig 200 is transferred, the stop block 32 in the stop groove 14 can directly receive the impact force, disperse the impact energy, and reduce the vibration transmitted to the assembly jig 200, thereby avoiding displacement or damage of the jig due to instantaneous impact, and ensuring the reliability and assembly accuracy of the production line in frequent conveying operations.

[0065] By setting the stopper 32, the hard collision between the bottom plate 10 and the stop point of the production line is effectively avoided, the damage risk of the jig carrying device 100 or the assembly jig 200 is reduced, the positioning deviation and the equipment wear are prevented from being aggravated, and the assembly precision and the continuous and stable operation of the production line are ensured.

[0066] In some embodiments of the present application, referring to Figure 2 and Figure 4 , the jig carrying device 100 further comprises a wear-resistant sheet 33 for supporting the bottom plate 10, and the wear-resistant sheet 33 at least partially protrudes from the second surface 12.

[0067] The wear-resistant sheet 33 is used to bear the friction load and reduce the wear of the bottom plate 10, and the wear-resistant sheet 33 can be made of a wear-resistant material such as stainless steel or hard alloy.

[0068] The wear-resistant sheet 33 at least partially protruding from the second surface 12 means that the end surface (bottom surface) of the wear-resistant sheet 33 is higher than the second surface 12 of the bottom plate 10, so that the protruding part is preferentially contacted with the conveying mechanism and bears the friction, thereby protecting the body of the bottom plate 10 from damage.

[0069] By setting the wear-resistant sheet 33, the wear of the second surface 12 of the bottom plate 10 is effectively reduced, the deformation or unevenness caused by wear is avoided, the horizontal posture stability and positioning precision of the jig carrying device 100 in the conveying process are ensured, and the generation of wear debris is reduced, thereby reducing the maintenance cost.

[0070] In some embodiments of the present application, referring to Figure 2 and Figure 4 , the second surface 12 of the bottom plate 10 is provided with a holding groove 15 at both ends perpendicular to the conveying direction X, and the wear-resistant sheet 33 is arranged in the holding groove 15.

[0071] Perpendicular to the conveying direction X means that the direction perpendicular to the conveying direction X is in the same horizontal plane. The holding groove 15 refers to a recess structure provided on the second surface 12 of the bottom plate 10, which can be designed as a rectangular, U-shaped or circular groove to accurately position the wear-resistant sheet 33 and ensure that the high wear position is covered. By designing the holding groove 15, the positioning and installation of the wear-resistant sheet 33 are facilitated.

[0072] In some embodiments, the holding groove 15 is designed as a shallow rectangular groove, and the wear-resistant sheet 33 is a rectangular block which slightly protrudes from the second surface 12 of the bottom plate 10 after installation to bear the friction load in the conveying process.

[0073] In some embodiments of the present application, referring to Figure 1The jig carrying device 100 further comprises at least two positioning blocks 34 fixedly connected to the first surface 11; a surface of the positioning block 34 away from the first surface 11 forms a bearing surface 341 for cooperating with a positioning reference surface of a jacking mechanism on the production line to keep the bottom plate 10 in a horizontal posture when jacked by the jacking mechanism.

[0074] The positioning block 34 is a fixed component for providing a horizontal positioning reference, which can be a metal block or an engineering plastic block, and is fixedly connected to the first surface 11 to ensure positional stability.

[0075] The top surface (end surface away from the first surface 11) of the positioning block 34 forms the bearing surface 341, which directly contacts the positioning reference surface of the jacking mechanism and has a planar surface to uniformly transmit the support force and automatically correct the posture.

[0076] The bearing surface 341 of the positioning block 34 directly cooperates with the positioning reference surface of the jacking mechanism to form a constraint point when the jacking mechanism is in action, thereby avoiding tilting due to manufacturing tolerances or uneven external forces; meanwhile, the geometric characteristics of the bearing surface 341 ensure that the support force is uniformly distributed, so that the bottom plate 10 is automatically adjusted to a horizontal state during jacking and finally maintains the precise positioning of the assembly jig 200.

[0077] The jacking mechanism is used to jack the jig carrying device 100, so that the jig carrying device and the carried assembly jig 200 are temporarily separated from the assembly line, and the assembly jig 200 is transferred to the corresponding station, and therefore the positioning block 34 can effectively prevent the posture of the bottom plate 10 from deviating during jacking, ensuring the positioning accuracy of the assembly jig 200 and improving the stability of the transferred assembly jig 200 and the accuracy of the assembly of the mobile phone hinge.

[0078] In addition, the positioning block 34 is provided with a insertion hole 342, and the positioning reference surface of the jacking mechanism is provided with a insertion column, when the bearing surface 341 of the positioning block 34 is attached to the positioning reference surface of the jacking mechanism, the insertion column is inserted into the insertion hole 342, so as to further position and improve the positioning accuracy.

[0079] After the jacking mechanism jacks the jig carrying device 100 and keeps the bottom plate 10 of the jig carrying device 100 in a horizontal posture, the jig carrying device 100 is received by other supporting mechanisms, and the jacking mechanism retreats to ensure that the jig carrying device 100 behind on the assembly line can normally flow.

[0080] In some embodiments of the present application, referring to Figure 1 , Figure 3 and Figure 4 , the bottom plate 10 is provided with at least two support holes 16 for insertion and cooperation with the support column of the jacking mechanism of the production line.

[0081] The support hole 16 refers to a hole-shaped structure formed on the bottom plate 10 for mechanical docking with the support column of the jacking mechanism, which can be realized in the form of a circular hole, a square hole or a special-shaped hole. In some embodiments, the support hole 16 is a circular through hole, which is arranged at the opposite corners of the bottom plate 10, facilitating quick plug-in cooperation with the support column of the production line jacking mechanism, and at the same time achieving stable support by using the rigid structure of the bottom plate 10 itself.

[0082] The arrangement of at least two support holes 16 ensures uniform force distribution at multiple points, preventing the bottom plate 10 from rotating or tilting during jacking due to single-point support; the plug-in cooperation mode of the support hole 16 and the support column realizes quick and accurate mechanical alignment, effectively inhibiting relative sliding during jacking, preventing the bottom plate 10 from tilting and vibrating during jacking, thereby ensuring accurate positioning of the assembly jig 200 during transfer and ensuring the stability and reliability of the production line operation.

[0083] In some embodiments of the present application, please refer to Figure 1 , the first surface 11 is provided with a two-dimensional code identification piece 35.

[0084] The two-dimensional code identification piece 35 refers to an identification component for obtaining identification information through optical scanning, which can be realized by printing a two-dimensional code label on the first surface 11 of the bottom plate 10, etching a two-dimensional code pattern on the surface of the bottom plate 10, or pasting a two-dimensional code sticker on the first surface 11.

[0085] By arranging the two-dimensional code identification piece 35, the visual system can quickly identify at the assembly station or the feeding and discharging station, and can be used for real-time binding of the identity information of the assembly jig 200 (such as jig number, current process state, number of uses, etc.).

[0086] In some embodiments of the present application, please refer to Figure 4 , the second surface 12 is provided with an RFID tag piece 36.

[0087] The RFID tag piece 36 refers to an electronic tag for realizing non-contact data exchange through wireless radio frequency, which can be realized by an embedded RFID chip, a pasted RFID tag or an RFID module integrated in the bottom plate 10.

[0088] By arranging the RFID tag piece 36, data can be automatically read or written without exposure and shutdown. The RFID tag can be repeatedly read and written, and can record dynamic information such as the number of uses and the flow path of the jig in real time, and can realize full-process closed-loop tracing. From warehousing, online, each station operation to offline, maintenance, all node data can be automatically associated to the unique ID of the RFID, and complete generation data is constructed.

[0089] The embodiment of the present application provides an assembly production line, which comprises a conveying mechanism and a jig carrying device 100 arranged on the conveying mechanism, and the jig carrying device 100 is the above-mentioned jig carrying device 100.

[0090] The assembly production line comprises the conveying mechanism, and can further comprise an identification mechanism, a stop mechanism, a jacking mechanism, a transfer mechanism, a feeding mechanism and a control system and the like.

[0091] The jig carrying device 100 is located on the conveying mechanism, the assembly jig 200 is installed on the jig carrying device 100 and follows the conveying mechanism to be conveyed to a corresponding station, and the assembly jig 200 is transferred to the corresponding station by the jacking mechanism and the transfer mechanism and the like.

[0092] Since the assembly jig 200 does not need to be integrated with a complex docking structure, the overall volume is reduced, the flexibility of carrying and operating between stations is improved, the rhythm is improved, and the space utilization rate of the production line is optimized.

[0093] The above merely describes the preferred embodiment of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
