[0002] During the assembly process of various electronic products in Shengchang, it is necessary to produce and test each component and then perform corresponding assembly one by one. The processing and testing requirements of different components are different. For example, in the process of manufacturing the metal middle frame of a mobile phone with a metal appearance, it is necessary to perform surface treatments such as electroplating on the metal surface of the product. Before the surface treatment, the antenna partition strip of the mobile phone metal middle frame needs to be covered to ensure that the surface treatments such as electroplating will not affect the partition strip and ensure the overall aesthetics. The existing technology is to use jigs corresponding to products one by one, and manually or automatically move the jigs to the pad printer for pad printing. Since there are processing errors between multiple different jigs and there are also certain processing errors between products, adjusting through different jigs will affect the accuracy of the pattern pad printed on the antenna partition strip of the metal frame, resulting in a poor pad printing effect for electroplating, a low yield rate of products leaving the factory, and not meeting the requirements of automated production. If a horizontal pick-and-place positioning jig for the pad printing process with a simple structure, a flat pick-and-place method for products, improved clamping stability through a fixed method of pulling the inner frame of the product at multiple points, and accurate positioning adjustment of the product after flipping can be designed, the above problems can be solved.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Such as Figures 1 to 8As shown in the figure, in this embodiment, the present invention includes a support base plate 1, a rotary jig 2, an opening and closing assembly 3, and a support and positioning assembly 4. The rotary jig 2 includes a hollow rotary module 5 and a product jig 6. The hollow rotary module 5 includes a rotary motor 51 and a rotary bracket 52. Both ends of the product jig 6 are rotatably matched with two groups of the rotary brackets 52 respectively. The rotary motor 51 is arranged on one side of a group of the rotary brackets 52 and is rotatably matched with one end of the product jig 6. The opening and closing assembly 3 is respectively matched with the pressing end and the positioning end on both sides of the product jig 6. The support and positioning assembly 4 is matched with the middle frame product 7 on the product jig 6. Thus, it can be seen that the rotary motor 51 drives the product jig 6 to usually achieve the flat placement of the middle frame product 7 without being interfered by other components. The opening and closing assembly 3 can press the opening and closing linkage structures on both sides of the product jig 6, so that the product jig 6 can stably fix the middle frame product 7. The rotary motor 51 realizes the adjustment of 90° clockwise or 90° counterclockwise and cooperates with the support and positioning assembly 4 to realize the adjustment of the middle frame product 7 in the Z-axis direction. The structure is simple and the positioning accuracy is high.
[0017] As Figures 2 to 4 shown, in this embodiment, the product jig 6 includes a rotating base plate 61, a product floating plate 62, an inner support pressing edge 63, an inner support positioning edge 64, and a product support block 65. The product floating plate 62 is connected to the rotating base plate 61 through a plurality of floating guide rails 66. A plurality of the product support blocks 65 are arranged on the upper end surface of the floating plate 62. Two groups of the inner support pressing edges 63 are connected to both sides of the product floating plate 62 through a plurality of groups of pressing slide rails 67. A plurality of first positioning blocks 68 on the upper end surface of the inner support pressing edge 63 are matched with one side of the inner frame of the middle frame product 7. A plurality of second positioning blocks 69 on the upper end surface of the inner support positioning edge 64 are matched with the other side of the inner frame of the middle frame product 7. Thus, it can be seen that the adsorption surface of the middle frame product 7 is matched with two groups of the product support blocks 65, and the product can be stably placed on the product floating plate 62. The inner frame of the middle frame product 7 is fixed by pulling in the reverse direction through a plurality of the first positioning blocks 68 and a plurality of the second positioning blocks 49, so that the middle frame product 7 can be stably fixed on the product support block 65.
[0018] As Figure 3 shown, in this embodiment, product guide blocks 8 are arranged at both ends of the product floating plate 62. Two groups of the product guide blocks 8 are respectively matched with both ends of the middle frame product 7. Thus, it can be seen that a plurality of the guide blocks 8 play a role of guiding and preliminary positioning when the middle frame product 7 is placed flat on two groups of the product support blocks 65.
[0019] As Figure 3As shown, in this embodiment, buffer blocks 9 are provided on the sides corresponding to the inner support pressing edge 63 and the inner support positioning edge 64. The two groups of buffer blocks 9 are respectively connected to the inner support pressing edge 63 and the inner support positioning edge 64 through a plurality of return springs 10, and the two groups of buffer blocks 9 are respectively matched with both sides of the product support block 65. Thus, the plurality of return springs 10 press the inner support pressing edge 61 and the inner support positioning edge 64 outward, providing a pressing force for the plurality of first positioning blocks 68 and the plurality of second positioning blocks 49, so that the middle frame product 7 can be stably fixed on the product support block 65.
[0020] As Figure 1 and Figure 6 As shown, in this embodiment, the opening and closing assembly 3 includes a pressing edge opening module 31 and a positioning edge opening module 32. The pressing edge opening module 31 and the positioning edge opening module 32 are respectively arranged on both sides of the support bottom plate 1, and the movable ends of the pressing edge opening module 31 and the positioning edge opening module 32 are respectively matched with the inner support pressing edge 63 and the inner support positioning edge 64. Thus, when the movable ends of the pressing edge opening module 31 and the positioning edge opening module 32 are pushed out, they respectively press the inner support pressing edge 63 and the inner support positioning edge 64, so that the plurality of first positioning blocks 68 and the plurality of second positioning blocks 49 move closer to each other and are in an unlocked state. After the middle frame product 7 is placed, the movable ends of the pressing edge opening module 31 and the positioning edge opening module 32 are reset, and the plurality of first positioning blocks 68 and the plurality of second positioning blocks 49 can move in opposite directions and press both sides of the inner frame of the middle frame product 7.
[0021] As Figure 1 and Figure 5As shown in the figure, in this embodiment, the support and positioning assembly 4 includes a cylinder bracket 41, a side-pushing cylinder 42, a downward-pressing cylinder 43, and a push plate 44. Two sets of the cylinder brackets 41 are respectively arranged on both sides of the support bottom plate 1. Two sets of the side-pushing cylinders 42 are respectively arranged at the upper ends of the two sets of the cylinder brackets 41. Two sets of the downward-pressing cylinders 43 are respectively connected to the movable ends of the two sets of the side-pushing cylinders 42 through two sets of docking plates 45. The push plate 44 is arranged on the pressing side of the docking plate 45. A lower pressing plate 46 is arranged at the movable end of the downward-pressing cylinder 43. A number of pressing blocks 47 on the lower pressing plate 46 cooperate with one side of the inner frame of the middle frame product 7. A number of supporting blocks 48 on the push plate 44 cooperate with the supporting surface 11 on one side of the positioning surface of the middle frame product 7. Thus, it can be seen that when the rotating motor 51 rotates by a certain angle, the middle frame 7 of the product will move downward by a certain distance due to the gravity and the elastic force of each spring. The downward-pressing cylinder 43 drives the pressing blocks 47 to press the middle frame product 7 downward, so that the supporting surface 11 of the middle frame product 7 cooperates with a number of the supporting blocks 48 on the push plate 44, making the positioning points of the middle frame product 7 stable and accurate.
[0022] As Figure 2 and Figure 3 shown in the figure, in this embodiment, angle sensors 12 are arranged at the upper end of the other set of rotating brackets 52 and on both sides. An induction tab 13 is arranged at the upper end of the corresponding side of the rotating bottom plate 61 and the angle sensors 12. The induction tab 13 is inductively matched with a number of the angle sensors 12. Thus, it can be seen that the three sets of angle sensors 12 can respectively identify three states of the rotating bracket 52 in a flat state, rotating 90° clockwise, and rotating 90° counterclockwise, meeting the requirements for the pad printing angle of the middle frame product 7.
[0023] As Figure 3 shown in the figure, in this embodiment, a number of suction cups 14 are arranged on a number of the product support blocks 65. A vacuum generator 15 is arranged on one side of the support bottom plate 1. The vacuum generator 15 is adsorbed and matched with the adsorption surface of the middle frame product 7 through a number of the suction cups 14. Thus, it can be seen that a number of the suction cups 14 can stably adsorb the middle frame product 7 on the product support blocks 65.
[0024] As Figure 4 shown in the figure, in this embodiment, floating positioning plates 16 are arranged on both sides of the product floating plate 62. The floating positioning plates 16 are matched with both sides of the rotating bottom plate 61 through a number of floating springs. Thus, it can be seen that the floating positioning plates 16 provide a buffering effect for the movement and flipping of the product floating plate 62 through a number of floating springs, and provide a reset force during the positioning adjustment process.
[0025] As Figure 6As shown in the figure, in this embodiment, an installation hole 17 is provided in the middle of the support bottom plate 1, and the installation hole 17 is matched with the installation end of the external machine tool equipment. It can be seen that the installation hole 17 is connected to the installation end of the external machine tool equipment.
[0026] Working principle of the present invention: When placing the middle frame product 7 to be pad-printed, the support and positioning assembly 4 is in a reset state, the two product support blocks 65 are in a horizontal state, triggering the angle sensor 12 at the highest point. The movable ends of the pressing edge opening module 31 and the positioning edge opening module 32 extend, and the inner support pressing edge 63 and the inner support positioning edge 64 move towards each other respectively. Manually or by a robot, the middle frame product 7 is placed flat on the jig. The adsorption surface of the middle frame product 7 needs to fit the upper surfaces of the two product support blocks 65. The movable ends of the pressing edge opening module 31 and the positioning edge opening module 32 are reset. Under the action of several reset springs 10, the inner support pressing edge 63 and the inner support positioning edge 64 respectively perform a pressing operation on both sides of the inner frame of the middle frame product 7. At the same time, the vacuum generator 15 is triggered to make several suction cups 14 suck tightly the middle frame product 7 to complete the feeding.
[0027] Before pad-printing the product, the rotation motor 51 drives the rotation bracket 52 to rotate clockwise by 90°, triggering the angle sensor 12 at the corresponding position. At this moment, the movable end of the side push cylinder 42 facing the positioning surface of the middle frame product 7 extends. At this moment, the part of the product support block 65 in direct contact with the middle frame product 7 will move downward by about 1 mm under the influence of gravity. The top surfaces of several support blocks 48 are about 1 mm away from the support surface 11 of the middle frame product 7. The movable end of the downward pressing cylinder 43 extends, and several pressing blocks 47 on the lower pressing plate 46 apply a vertically downward force to the middle frame product 7. Several floating springs between the corresponding floating positioning plate 16 and the rotating bottom plate 61 are compressed. The corresponding support surface 11 on the middle frame product 7 moves downward to fit the top surface of the support block 48, completing the positioning of the middle frame product 7 in the Z-axis direction.
[0028] After the two antenna partition strips on one side of the metal frame of the middle frame product 7 are completed with pad-printing coverage, the movable end of the downward pressing cylinder 43 is reset. The support surface 11 moves upward under the elastic force of the floating spring. The side push cylinder 42 drives the support block 48 to reset. The rotation motor 51 drives the rotation bracket 52 to rotate counterclockwise by 180°, repeating the above steps to complete the positioning of the middle frame product 7 in another state in the Z-axis direction.
[0029] After pad-printing is completed on both sides, each component is reset. The product jig 6 is in a flat state. Replace the new middle frame product 7 and repeat the above steps to realize the horizontal pick-and-place positioning in the pad-printing process of the middle frame product.
[0030] Although the embodiments of the present invention are described in terms of actual solutions, they do not constitute a limitation on the meaning of the present invention. For those skilled in the art, modifications to its implementation solutions according to this specification and combinations with other solutions are obvious.
