[0001] The present invention relates to the technical field of feeding equipment, in particular to a positioning and transferring mechanism, a clean multi-functional feeding equipment and a feeding method thereof. Background Art

[0002] In the production and manufacturing process of the electronic assembly industry, there is a need to separately pick up electronic components for testing or assembly work. Electronic component materials are usually centrally placed in a tray, which is convenient for the orderly storage and transfer of materials.

[0003] In order to meet the batch requirements of testing, assembly, and processing, special fixtures matching the processes are usually adopted. Multiple components are simultaneously clamped by the special fixture, and synchronous processing operations are performed on the multiple components to improve efficiency.

[0004] In the prior art, a manipulator is used to transfer components from the tray to the special fixture to complete the transfer and feeding of the components. Usually, it is just a simple handling. During the transfer process of the manipulator, it may simultaneously meet the changing requirements of the spacing between adjacent components, and the overall function is relatively single.

[0005] When further adjustment and preparation operations, such as positioning and flipping, are required for the components in the special fixture before subsequent testing, assembly, and processing, the corresponding clamping mechanism takes the components from the special fixture, adjusts the posture and positions them, and then performs the processing operation process. The existing operations before actual processing have repeated actions of clamping and transferring, redundant processes, the special fixture fails to reflect its role dedicated to actual processing, and the overall equipment has a large number of mechanisms and occupies a large space.

[0056] The following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0057] As Figure 4 and Figure 5 shown, a positioning and transfer mechanism in this embodiment includes a Y-direction positioning and transfer module 51. A U-shaped seat 52 is installed on the Y-direction positioning and transfer module 51. A support plate 521 is installed at the upward opening end of the U-shaped seat 52. A positioning seat 54 is installed on the top surface of the support plate 521. Multiple positioning points are provided on the top surface of the positioning seat 54, and products 10 are placed one by one corresponding to the positioning points. Limit blocks 56 are respectively installed on the positioning seats 54 at adjacent two sides of the product 10, and movable blocks 55 are respectively rotatably installed on the positioning seats 54 at the other adjacent two sides of the product 10 via positioning shafts 551. A force-receiving end and a pressing end are provided on the movable block 55. An elastic body 552 is installed between the movable block 55 and the positioning seat 54, and the elastic body 552 urges the pressing end of the movable block 55 to abut against the product 10. An external driving power applies a force to the force-receiving end to drive the pressing end of the movable block 55 to disengage from the product 10.

[0058] In this embodiment, the external driving power is a linear driving power 53 installed inside the U-shaped seat 52. A plurality of ejector rods 531 are installed at the upward output end of the linear driving power 53. The ejector rods 531 push the movable block 55 upward to overcome the elastic force of the elastic body 552 and rotate to unlock the abutment against the product 10.

[0059] In the positioning and transfer mechanism 5 of this embodiment, while realizing the transfer of the product 10, it also realizes the reliable positioning of the product 10, effectively ensuring the positioning effect.

[0060] In this embodiment, as Figure 6 shown, the positioning seat 54 includes a positioning upper plate 543 and a positioning lower plate 542 which are stacked and installed up and down. The positioning shaft 551 can be installed between the positioning upper plate 543 and the positioning lower plate 542. The movable block 55 can pass upward through the positioning upper plate 543 to abut against the product 10. The elastic body 552 can be installed between the movable block 55 and the corner seat 541 below the positioning lower plate 542, so as to achieve a reasonable spatial layout, which is convenient for the installation, maintenance and adjustment of the positioning and transfer mechanism 5.

[0061] As Figure 1 、 Figure 2 and Figure 3 shown, this embodiment also proposes a clean and multifunctional loading device, which includes a working platform 1. Along the X direction, a tray loading and unloading station 2 and a fixture return loading station 8 are arranged at intervals on the working platform 1. Along the Y direction, a transfer mechanism one 4 and a transfer mechanism two 6 are arranged at intervals on the working platform 1. A positioning and transfer mechanism 5 is installed on the working platform 1 inside the enclosed space surrounded by the tray loading and unloading station 2, the fixture return loading station 8, the transfer mechanism one 4 and the transfer mechanism two 6; it also includes a flipping mechanism 3 horizontally arranged above the tray loading and unloading station 2.

[0062] In this embodiment, the tray loading and unloading station 2 and the fixture return loading station 8 are arranged in parallel at intervals. Combined with the transfer mechanism one 4 and the transfer mechanism two 6 arranged in parallel at intervals, a compact enclosed space is formed. The positioning and transfer mechanism 5 is arranged in the enclosed space, and the process flow of the product 10 is carried out. The overall process is simplified, the structure is optimized, and the layout is full and coordinated.

[0063] During actual use, the flipping mechanism 3 takes the material from the tray 100 at the tray loading and unloading station 2 and flips it. Combining the transfer mechanism one 4, the positioning and transfer mechanism 5 and the transfer mechanism two 6, the product 10 is positioned and transferred and clamped in the fixture 200 at the fixture return loading station 8. The fixture 200 is connected to the subsequent processing process and directly processed; thus, while loading the material, operations such as flipping and positioning of the product 10 before processing are realized, making the machine multifunctional, matching the subsequent automated processing, and helping to improve the efficiency.

[0064] The positioning and transfer mechanism 5 not only transfers the product 10 from the first transfer mechanism 4 to the second transfer mechanism 6, but also can realize reliable positioning of the product 10 through the movable block 55. The overall structure is flexible and convenient to use.

[0065] As Figure 7 shown, the structure of the tray loading and unloading station 2 is as follows: it includes a translation track 21 arranged along the Y direction, with lifting and folding tray mechanisms respectively arranged at both ends of the translation track 21, and also includes a clamping and translation mechanism 22 located inside the translation track 21 and connected between the two groups of lifting and tray removing mechanisms; three working positions, namely the tray loading position, the product clamping position, and the tray unloading position, are sequentially arranged along the length direction of the translation track 21, and the clamping and translation mechanism 22 clamps the tray 100 and stays at the three working positions; the clamping and translation mechanism 22 includes a clamping group driven by a Y-direction translation module 221, and the clamping group clamps the opposite sides of the tray 100 in the moving direction.

[0066] In this embodiment, the clamping and translation mechanism 22 placed below the translation track 21 in the tray loading and unloading station 2 is used to realize the transfer of the tray 100 between two adjacent moving points among the three positions, which is convenient for the layout and operation of the flipping mechanism 3 above the translation track 21 and the clamping operation of the first transfer mechanism 4.

[0067] In this embodiment, the lifting and folding tray mechanism can adopt existing conventional mechanisms. For example, it includes a stacking bracket 24 arranged vertically, with lateral clamping mechanisms 25 installed on the relative two sides below the stacking bracket 24, combined with a lifting member 26 driven by a lifting power 27. By clamping on both sides and lifting or descending, the empty trays can be stacked upwards or the full trays can be disassembled downwards. A first scanning code component 23 can also be arranged to facilitate subsequent traceability.

[0068] As Figure 8 shown, the structure of the clamping and translation mechanism 22 can be: it includes a Y-direction translation module 221, and two groups of clamping groups are installed at intervals along the Y direction on the translation seat 222 at the output end of the translation module. Each single clamping group includes a pair of clamping blocks one 225 and clamping blocks two 226; the clamping block one 225 is rotatably installed on the fixed seat 223 on the top surface of the translation seat 222 through a rotating shaft one 224, and a moving seat 229 is installed on the top surface of the translation seat 222 through a Y-direction moving power 228. The clamping block two 226 is installed on the moving seat 229 through a rotating shaft two 227; the clamping block one 225 and the clamping block two 226 are respectively driven by corresponding driving powers to rotate around the corresponding rotating shaft one 224 and rotating shaft two 227 to realize the clamping or detachment of the tray 100.

[0069] As Figure 9 and Figure 10As shown in the figure, the translation track 21 includes track members 211 arranged at intervals along the X direction. Opposite side surfaces of the track members 211 are provided with grooves 2111 along the Y direction. A plurality of support blocks 212 are installed along the length direction in one side groove 2111. The support blocks 212 elastically contract along the width direction of the translation track 21. For example, a spring is installed between the support blocks 212 and the track members 211 to form an elastic structure. A plurality of vertically axial rolling members 213 are orderly installed along the length direction in the other side groove 2111.

[0070] In this embodiment, the edge of the tray 100 clamped and moved by the clamping and translation mechanism 22 is placed in the groove 2111 of the translation track 21. The support blocks 212 and the rolling members 213 are combined to achieve and ensure the positioning and smooth movement of the tray 100. The tray can move along the groove 2111 driven by the clamping and translation mechanism 22.

[0071] As Figure 11 shown in the figure, the flipping mechanism 3 includes a rotating shaft seat 33 arranged axially along the X direction. A plurality of fixing blocks 35 are installed axially on the rotating shaft seat 33. The fixing blocks 35 are slidably equipped with an adsorption seat 36. The bottom surface of the adsorption seat 36 is provided with adsorption holes communicated with an external air source. It also includes a flipping driving power 34 for driving the axial rotation of the rotating shaft seat 33 and a lifting driving power for driving the up and down movement of the rotating shaft seat 33.

[0072] In this embodiment, a flipping support 31 is installed on the working platform 1. The flipping support 31 is slidably installed with a lifting seat 32 with a U-shaped opening facing upwards through a guide rail and slider assembly. Both ends of the rotating shaft seat 33 are rotatably installed at the opening end of the lifting seat 32 to form a structural support for the rotating shaft seat 33. The translation track 21 passes through the inside of the lifting seat 32. The rotating shaft seat 33 is located above the translation track 21. When the lifting seat 32 moves downward, the product 10 in the tray 100 on the translation track 21 is adsorbed downward by the adsorption seat 36 on the rotating shaft seat 33, and then the rotating shaft seat 33 moves upward and is driven by the flipping driving power 34 to flip 180° upwards.

[0073] In this embodiment, after the flipping mechanism 3 flips the product 10 upwards, before the transfer mechanism 4 clamps the product 10, visual inspection of the product 10 can be arranged according to actual needs, and NG products can be removed during subsequent transfer.

[0074] As Figure 12As shown, the first transfer mechanism 4 includes an X-direction transfer module 41 and a Z-direction transfer module 42. The output part of the Z-direction transfer module 42 is installed with a rotation driving power source 44 through a lifting support 43. The downward output end of the rotation driving power source 44 is installed with a plurality of first transfer clamping components 46 through a rotating seat 45. After clamping a plurality of products 10 arranged along the width direction of the translation track 21 from the flipping mechanism 3, the plurality of products 10 can be rotated in the arrangement direction through the operation of the rotation driving power source 44, for example, rotated by 90° to be arranged along the Y direction.

[0075] As Figure 13 shown, the second transfer mechanism 6 includes an X-direction transfer module 61, a Y-direction transfer module 62, and a Z-direction transfer module 63. One side of the lifting support 64 installed on the output part of the Z-direction transfer module 63 is installed with a second transfer clamping component 65 corresponding to the first transfer clamping component 46, and the other side of the lifting support 64 is installed with a material removing and replenishing clamping component 68 through a lifting cylinder 67.

[0076] The first transfer clamping component 46, the second transfer clamping component 65, and the material removing and replenishing clamping component 68 have the same structure. The specific structure is: As Figure 14 shown, it includes a clamping cylinder 651. One inner side of one of the two clamping jaws 653 at the output end of the clamping cylinder 651 is installed with a limiting post 652. The side of the clamping cylinder 651 is also slidably installed with a pressing block 656 through a vertical guiding component 654. The end of the pressing block 656 extends between the two clamping jaws 653. It also includes an elastic member 655 providing vertical elastic buffering for the pressing block 656, effectively ensuring the clamping of the product 10, especially ensuring the stable clamping and transfer of the positioned product 10. A connecting block 66 is also commonly installed between the corresponding same-side clamping jaws 653 of multiple second transfer clamping components 65.

[0077] It further includes a replenishing mechanism 7. As Figure 15 shown, the replenishing mechanism 7 is installed on the working platform 1 below the traveling direction of the second transfer mechanism 6. The replenishing mechanism 7 includes a replenishing seat 73. The replenishing seat 73 is provided with a plurality of material grooves 731 for accommodating the products 10. The products 10 are clamped and limited in the material grooves 731, and the clamping of the products 10 at the material grooves 731 is unlocked by an unlocking power source 74. During the transfer process of the second transfer mechanism 6, material can be removed or replenished from the replenishing mechanism 7 through the material removing and replenishing clamping component 68 according to requirements.

[0078] In this embodiment, an NG product seat 72 can also be set in the replenishing mechanism 7 for placing the products detected as NG in the previous process. The NG product seat 72 and the replenishing seat 73 are installed side by side on the top surface of the supporting seat 71. The positioning structure in the positioning and transfer mechanism 5 can be referred to, and movable blocks 55 are arranged in the circumferential direction of the material grooves 731 to realize the positioning placement of the products 10 in the replenishing seat 73, and the unlocking is performed by the unlocking power source 74.

[0079] As Figure 16 shown, the structure of the fixture return loading station 8 is as follows: It includes a conveyor line 82 and a return line 81 arranged in upper and lower layers. A fixture lifting connection line 88 is installed at the ends of the conveyor line 82 and the return line 81. The fixture 200 is transferred from the lower return line 81 to the upper conveyor line 82. Along the conveying direction of the conveyor line 82, a detection and unlocking mechanism 86, a loading and unlocking mechanism 84, and an NG fixture bin 83 are arranged in sequence. The NG fixture on the conveyor line 82 can be laterally pushed into the NG fixture bin 83 by a linear pushing mechanism. A vision component 85 is arranged above the detection and unlocking mechanism 86, and the vision component 85 detects the fixture 200. According to actual requirements, a second code scanning component 87 can also be arranged to facilitate subsequent information traceability.

[0080] In this embodiment, the fixture lifting connection line 88 can adopt an existing conventional structure, such as a connection conveying member driven by a lifting cylinder to move up and down, which is horizontally aligned with one of the conveyor line 82 or the return line 81 to perform horizontal docking of the fixture 200.

[0081] As Figure 19 shown, the structure of the fixture 200 is as follows: It includes a fixture upper plate 201 and a fixture lower plate 206 installed in upper and lower laminations. A plurality of accommodation grooves 2011 for accommodating the product 10 are formed on the top surface of the fixture upper plate 201. Between the fixture upper plate 201 and the fixture lower plate 206, a first movable member 202 is installed via a horizontal rotating shaft 203, and a second movable member 205 is installed via a vertical rotating shaft 204. The ends of the first movable member 202 and the second movable member 205 respectively pass upward through the fixture upper plate 201 and are located at adjacent edges of the accommodation groove 2011. The accommodation groove 2011 combines with the first movable member 202 and the second movable member 205 to realize the positioning and clamping of the product 10 in the fixture 200. Springs for resetting and maintaining the positioning and clamping state can also be provided on the first movable member 202 and the second movable member 205.

[0082] As Figure 17 and Figure 18 shown, the structure of the detection and unlocking mechanism 86 is as follows: It includes a Y-direction seat 842. A horizontal unlocking power 843 is installed on the top surface of the Y-direction seat 842. The push rod 844 at the output end of the horizontal unlocking power 843 horizontally applies force to the second movable member 205 in the fixture 200 on the conveyor line 82 to unlock the second movable member 205. An L-shaped pressing plate 846 is slidably installed on the side of the Y-direction seat 842. The pressing plate 846 is driven by a vertical unlocking power 845 to move up and down. The downward pressing plate 846 applies force to the first movable member 202 in the fixture 200 on the conveyor line 82 via the bottom convex column to unlock the first movable member 202.

[0083] Based on the detection unlocking mechanism 86, the loading unlocking mechanism 84 installs the Y-direction module 841 below the Y-direction seat 842. During use, the second transfer mechanism 6 grips four products 10 with a relatively large single clamping pitch at a time. Twelve products 10 can be closely arranged in the fixture 200. The products 10 placed by the transfer mechanism 6 can be matched by the movement of the loading unlocking mechanism 84 in the Y direction.

[0084] It further includes a housing 9 surrounding the outside of the clean multi-functional loading equipment. A air supply and filtration unit 91 is installed on the top of the housing 9. Airflow holes penetrating up and down are opened on the working platform 1. A air extraction component is installed inside the housing 9 below the working platform 1.

[0085] In the present invention, the flipping and positioning of the products 10 are integrated into the loading equipment. Through a compact layout, combined with the installation of the air supply and filtration unit 91 on the top, the opening of the airflow holes on the working platform 1, and the setting of the air extraction component below, the cleanliness of the products is effectively guaranteed, and even the standard of a hundred-class dust-free workshop for electronic components can be met.

[0086] The loading method of the clean multi-functional loading equipment in this embodiment includes the following steps:

[0087] Load the tray 100 filled with products 10 onto the tray loading and unloading station 2. The products 10 in the tray 100 are grabbed and flipped upwards by the flipping mechanism 3. The first transfer mechanism 4 grabs the products 10 from the flipping mechanism 3 and then transfers them to the positioning and transfer mechanism 5. The positioning and transfer mechanism 5 positions the products 10 and transfers them along the Y direction towards the second transfer mechanism 6. The second transfer mechanism 6 grabs and transfers the products 10 in the positioning and transfer mechanism 5 into the fixture 200 in the fixture return and loading station 8. Both the tray loading and unloading station 2 and the fixture return and loading station 8 are driven along the Y direction.

[0088] In the present invention, while loading, operations such as flipping and positioning before product processing are realized. It has multiple functions in one machine, simplifies the overall process, optimizes the structure, and has a compact and ingenious layout, greatly reducing space occupation and cost.

[0089] In this specification, each embodiment is described in a progressive manner. The key points of each embodiment are all the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0090] The above description is an explanation of the present invention, not a limitation of the invention. The scope defined by the present invention can be seen in the claims. Within the protection scope of the present invention, any form of modification can be made.
