[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0044] like Figure 1 and Figure 2 As shown, the utility model provides a feeding device 100 for fixing and clamping a material 50 for subsequent process operations. The feeding device 100 includes a support member 10, a pressing member 20 and a locking member 30, wherein:

[0045] The support member 10 is used to support the material 50. The support member 10 is a plate structure. A positioning column 11 is protruded from the support member 10. The number, structure and distribution of the positioning columns 11 can be determined according to the number, structure and distribution of preset holes on the material 50 in the actual production process, and are not limited here.

[0046] In a feasible implementation manner, two preset holes are provided on the material 50, and the preset holes are arranged at intervals along the length direction of the material 50. Correspondingly, two positioning columns 11 are provided on the support member 10, and the two positioning columns 11 match the two preset holes one by one. In the embodiment provided in the present application, the first direction D1 is the axial direction of the positioning column 11, preferably the direction of gravity. The material 50 is placed vertically on the support member 10 from top to bottom along the direction of gravity to reduce scratches on the material 50. The positioning column 11 cooperates with the preset holes to limit the horizontal movement of the material 50.

[0047] like Figure 3 As shown, a positioning groove 12 is provided on the outer surface of the positioning post 11 . In a feasible implementation manner, the positioning groove 12 is recessed on the outer surface of the positioning post 11 and extends along the radial direction of the positioning post 11 .

[0048] The pressing piece 20 is used to clamp the material 50 together with the support 10. The pressing piece 20 can move along the first direction D1. The pressing piece 20 is close to the material 50 and contacts the material 50 in the first direction D1. In the initial state, the pressing piece 20 is away from the support 10 to avoid interfering with the process of assembling the material 50 on the support 10. After the material 50 is placed on the support 10, the pressing piece 20 moves along the first direction D1. Figure 4 or Figure 5 As shown, a positioning hole 21 is provided through the pressing piece 20, and the position of the positioning hole 21 matches the position of the positioning column 11. During the movement of the pressing piece 20, the positioning column 11 extends into the positioning hole 21, and the pressing piece 20 uses its own weight to press the material 50 against the support 10, thereby limiting the movement of the material 50 in the first direction D1 and preventing the material 50 from moving or tilting.

[0049] The locking member 30 is arranged on the side of the pressing member 20 away from the supporting member 10. The locking member 30 is used to lock the position of the pressing member 20, so as to prevent the locking member 30 from shifting during the movement of the feeding device 100, causing the material 50 to be scratched or fallen off. The locking member 30 can move along the second direction D2. The locking member 30 is arranged on the pressing member 20 and can move along the first direction D1 with the pressing member 20. At the same time, the locking member 30 can move horizontally relative to the pressing member 20 along the second direction D2. In the embodiment provided in the present application, the second direction D2 is the length direction of the pressing member 20, and the second direction D2 is perpendicular to the first direction D1.

[0050] like Figure 4 As shown, the locking member 30 includes a locking block 32, which is arranged corresponding to the positioning groove 12 on the positioning column 11, and the positioning groove 12 is located within the moving range of the locking block 32. The outer diameter of the locking block 32 is adapted to the inner diameter of the positioning groove 12. During the movement of the locking member 30, the locking block 32 extends into the positioning groove 12, and there is a very small gap between the outer wall surface of the locking block 32 and the inner wall surface of the positioning groove 12, forming a gap fit, thereby limiting the movement of the locking block 32 in the first direction D1. Since the locking member 30 and the pressing member 20 move synchronously in the first direction D1, the movement of the pressing member 20 along the first direction D1, that is, the direction of gravity, is also limited, so that the pressing member 20 maintains pressure on the material 50, avoids the movement of the material 50, and improves the tightness of the clamping of the material 50.

[0051] Further, refer to Figure 3 , Figure 6 as well as Figure 7 As shown, two positioning grooves 12 are provided. The two positioning grooves 12 are arranged oppositely on the outer surface of the positioning column 11 , and the positioning grooves 12 extend along the second direction D2 .

[0052] The locking member 30 includes two locking blocks 32, a locking groove 31 is formed between the two locking blocks 32, the locking groove 31 is arranged corresponding to the positioning column 11, the positioning column 11 is located within the moving range of the locking groove 31, and the locking groove 31 is formed at the end of the locking member 30. In the initial state, the locking member 30 is away from the positioning hole 21 to avoid interference with the assembly of the pressing member 20. After the pressing member 20 is pressed against the material 50, the positioning column 11 extends into the positioning hole 21 to form a clearance fit, and the locking member 30 is then moved along the second direction D2 moves, the positioning column 11 extends from the opening into the locking groove 31, and the positioning column 11 is clamped and fixed by the two locking blocks 32, so that the locking member 30 can only move along the second direction D2, thereby completing the clamping of the material 50, so that the support member 10, the pressing member 20, the locking member 30 and the material 50 are combined into a whole, and the material 50 has good fastness, which prevents the material 50 from rolling / swaying during the clamping and feeding process, resulting in low feeding efficiency and scratches, which can greatly improve the clamping efficiency and yield and reduce production scratches.

[0053] In order to guide the locking block 32 to smoothly enter the positioning groove 12, refer to Figure 4 As shown, a guide sliding arc surface 33 is formed at the corner end of the locking block 32, and the guide sliding arc surface 33 is located on opposite sides of the opening of the locking groove 31, thereby forming a flared structure, and the large diameter end of the flared structure is closer to the positioning column 11 than the small diameter end. During the movement of the locking member 30 along the second direction D2, even if there is an offset between the positioning column 11 and the locking groove 31, the flared structure can still enable the positioning column 11 to enter the locking groove 31, and the positioning groove 12 of the positioning column 11 first contacts the guide sliding arc surface 33, and the guide sliding arc surface 33 guides the locking groove 31 to align with the positioning column 11, so that the locking block 32 can smoothly extend into the locking groove 31.

[0054] Continue to refer to Figure 4 As shown, a guide plate 34 is provided on the pressing piece 20, and a gap is provided between the guide plate 34 and the pressing piece 20 to form a guide channel, and the locking piece 30 gap fits in the guide channel, and the guide plate 34 is used to guide the locking piece 30 to be slidably arranged on the side of the pressing piece 20 away from the support piece 10. The guide plate 34 can not only play a guiding role so that the locking piece 30 moves along the second direction D2, but also play a limiting role, so that the locking piece 30 can only move along the second direction D2, but cannot move along the first direction D1 relative to the pressing piece 20. It also plays a positioning role again, so that the locking block 32 is opposite to the positioning groove 12 on the positioning column 11, and the locking groove 31 between the two locking blocks 32 is opposite to the main body of the positioning column 11, to ensure that when the locking piece 30 moves, the positioning column 11 smoothly enters the locking groove 31 to complete the locking of the pressing piece 20.

[0055] In a feasible implementation mode, referring to Figure 4As shown, the guide plate 34 includes a transverse plate section 341 and a vertical plate section 342 located on opposite sides of the transverse plate section 341. The transverse plate section 341 extends in the horizontal direction, and the vertical plate section 342 extends in the first direction D1. The end of the vertical plate section 342 away from the transverse plate section 341 is connected to the pressing piece 20. The distance between the two vertical plate sections 342 is adapted to the width of the locking piece 30. The distance between the transverse plate section 341 and the pressing piece 20 is adapted to the thickness of the locking piece 30. The transverse plate section 341, the vertical plate section 342 and the pressing piece 20 together form a guide channel, which extends in the second direction D2. The locking piece 30 is gap-fitted in the guide channel to limit the movement of the locking piece 30 in other directions.

[0056] To limit the movement range of the locking member 30, refer to Figure 4 As shown, the locking member 30 is provided with a first limiting protrusion 35 and a second limiting protrusion 36, and the first limiting protrusion 35 and the second limiting protrusion 36 are respectively located at the opposite ends of the locking member 30 along the second direction D2, and the guide plate 34 is located between the first limiting protrusion 35 and the second limiting protrusion 36. When the locking member 30 moves to one end of the moving path, the first limiting protrusion 35 abuts against the guide plate 34, and when the locking member 30 moves to the other end of the moving path, the second limiting protrusion 36 abuts against the guide plate 34. In this way, the locking member 30 can move within a certain range without being separated from the pressing member 20, thereby losing the locking effect on the pressing member 20, causing the material 50 to roll / sway during the clamping and feeding process, resulting in low feeding efficiency and scratches.

[0057] Reference Figure 4 as well as Figure 5 As shown, a plurality of conductive ejector pins 22 are provided on the side of the pressing piece 20 facing the supporting piece 10. After the pressing piece 20 is placed on the material 50, the conductive ejector pins 22 are in contact with the surface of the material 50. The structure, number and distribution of the conductive ejector pins 22 can be selected according to actual needs and are not limited here. In a feasible application, the material 50 needs to undergo an anodic process. During the anodic process production, the material 50 needs to be immersed in the tank liquid of the anode cell for a long time. Preferably, the conductive ejector pins 22 are made of pure titanium, so as to conduct strong electricity, strengthen the reaction between aluminum and acid, and enhance the adsorption effect of aluminum on pigments.

[0058] In order to ensure that the positioning column 11 can be smoothly inserted into the positioning hole 21 during the movement of the pressing piece 20 along the first direction D1, and the horizontal movement of the pressing piece 20 is limited by the cooperation between the positioning column 11 and the positioning hole 21, refer to Figure 3 as well as Figure 4As shown, one end of the positioning hole 21 forms a first opening 23 on the side of the pressing piece 20 away from the support piece 10, and the first opening 23 is circular; the other end of the positioning hole 21 forms a second opening 24 on the side of the pressing piece 20 close to the support piece 10, and the second opening 24 is elliptical, wherein: the short axis length of the second opening 24 is equal to the inner diameter of the first opening 23, and the long axis length of the second opening 24 is greater than the inner diameter of the first opening 23, thereby forming the positioning hole 21 into a flared structure, and the large diameter end and the small diameter end of the flared structure are each close to the support piece 10.

[0059] In a feasible implementation, the first opening 23 is a circular hole with a diameter of 6 mm, and the second opening 24 is an elliptical hole with a diameter of 6*7 mm. The inner diameter of the first opening 23 matches the outer diameter of the positioning column 11, thereby limiting the radial movement of the pressing piece 20. At the same time, the inner diameter of the second opening 24 is larger than the outer diameter of the positioning column 11, so that when the pressing piece 20 is moved along the first direction D1, the second opening 24 can better align with the position of the positioning column 11 and guide the positioning column 11 into the positioning hole 21, while also improving the tolerance of the size and position of the positioning column 11.

[0060] Reference Figure 1 as well as Figure 2 As shown, the loading device 100 also includes a base plate 40, a guide rail 41, a guide block 42 and a slide 43. The guide rail 41 is arranged on the base plate 40, and the guide rail 41 extends along the third direction D3. The guide block 42 is slidably arranged on the guide rail 41. The bottom end of the slide 43 is fixed to the guide block 42, and the support member 10 is arranged at the top of the slide 43. In a feasible implementation manner, the third direction D3 is a horizontal direction, and the third direction D3, the second direction D2 and the first direction D1 are all perpendicular to each other. Those skilled in the art can know that the first direction D1, the second direction D2 and the third direction D3 can also be mutually crossed in pairs to form a preset angle, which is not limited here.

[0061] Reference Figure 1 As shown, in the initial state, the slide 43 is located at the starting end of the moving path, and the material 50 is placed on the support 10. Then the pressing piece 20 vertically descends along the first direction D1 to press the material 50 against the support 10. At this time, the positioning column 11 extends into the positioning hole 21 to limit the horizontal movement of the pressing piece 20. The locking piece 30 located on the surface of the pressing piece 20 moves horizontally along the second direction D2, so that the locking block 32 extends into the positioning groove 12 of the positioning column 11 to limit the movement of the pressing piece 20 in the direction of gravity, thereby completing the clamping of the material 50.

[0062] After the material 50 is clamped, the slide 43 moves along the third direction D3 to the end of the moving path, and the slide 43 is locked on the bottom plate 40. The operator can directly take out the loading device 100 with the clamped material 50, which can greatly reduce the scratches and defects in production.

[0063] Further, refer to Figure 1 as well as Figure 2 As shown, a locking piece 45 is provided on the bottom plate 40, and the locking piece 45 is used to lock the slide 43 on the bottom plate 40. In a feasible implementation manner, a locking slot is provided on the locking piece 45, and a card block is provided on the side of the slide 43 facing the locking piece 45. When the slide 43 moves along the third direction D3 to approach the locking piece 45, the card block is inserted into the locking slot to fix the slide 43, thereby limiting the movement of the slide 43, so that the slide 43 and the bottom plate 40 form a whole. At this time, the operator can directly take out the bottom plate 40 to transfer the material 50. Those skilled in the art can know that the direct locking cooperation between the slide 43 and the locking piece 45 can be achieved through more implementation methods, which are not limited here.

[0064] Furthermore, a buffer 44 is provided on the base plate 40, and the buffer 44 and the locking member 45 are arranged relative to each other along the third direction D3. The buffer 44 is located at the initial position of the slide 43, and the slide 43 rests on the buffer 44 for positioning. After the material 50 is clamped, it moves along the third direction D3 until it completes the locking cooperation with the locking member 45. The structure of the buffer 44 can refer to the buffer structure in the prior art, and will not be elaborated here.

[0065] In summary, refer to Figure 6 as well as Figure 7 As shown, the working process of the utility model is:

[0066] In the initial state, the slide 43 rests on the buffer 44 for positioning, and the material 50 is placed vertically on the support 10 from top to bottom. The positioning column 11 on the support 10 extends into the preset hole position of the material 50, and the pressing piece 20 then moves along the first direction D1 until it is pressed against the material 50. The positioning column 11 extends into the positioning hole 21 to form a clearance fit. The pressing piece 20 uses its own weight to press the material 50 against the support 10, limiting the movement of the material 50 in the first direction D1, and preventing the material 50 from moving or tilting.

[0067] The locking member 30 moves along the second direction D2, and the positioning column 11 extends from the opening into the locking groove 31. The positioning column 11 is clamped and fixed by two locking blocks 32, so that the locking member 30 can only move along the second direction D2, thereby completing the clamping of the material 50, so that the support member 10, the pressing member 20, the locking member 30 and the material 50 are combined into a whole, and the material 50 has better fastening.

[0068] After the material 50 is clamped, the slide 43 moves along the third direction D3 to the end of the moving path, and the slide 43 is locked on the bottom plate 40. The operator can directly take out the loading device 100 with the clamped material 50, which can greatly reduce the scratches and defects in production.

[0069] The feeding device 100 provided in the above embodiment has a relatively small dead weight, which avoids the rolling / swaying of the material 50 during the clamping and feeding process, resulting in low feeding efficiency and scratches, and can greatly improve the clamping efficiency and yield and reduce production scratches.

[0070] Those skilled in the art will know that in addition to being used in the manual clamping and feeding production of the anode process, it can also be used in the clamping and feeding production of the sandblasting process or the clamping and feeding and painting production of other plastic products. It can be applied in the future mobile phone production technology range, such as CNC, sandblasting, laser, assembly and other processes can all be used for reference, without limitation here. It is of great significance to improve the production efficiency and yield of the clamping and feeding device, and its promotion value is relatively high.

[0071] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
