Description

Technical Field

[0002] After the preliminary processing of metal profiles, in order to protect the main body of the profiles and prevent the main body metal of the profiles from being oxidized or corroded, the profiles are usually electroplated or electroless plated to form a protective film on the surface of the profiles, avoiding the oxidation of the profiles and improving the corrosion resistance of the profiles at the same time.

[0047] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0048] Example

[0049] In order to facilitate fixing of the profile X during chemical plating and improve the efficiency of fixing the profile X, the present invention provides a chemical plating bracket.

[0050] See also Figure 1-12, a chemical plating bracket provided by the present invention includes a first bracket 1, a second bracket 2, a connecting rod 3, and a placing plate 4. The first bracket 1 and the second bracket 2 are arranged oppositely and have the same structure, and both are "C"-shaped brackets with an upper opening. The connecting rod 3 is arranged between the first bracket 1 and the second bracket 2, and both ends of the connecting rod 3 are fixedly connected to the first bracket 1 and the second bracket 2 respectively. Through long holes are provided on both vertical parts of the "C"-shaped first bracket 1 with an upper opening, and the two long holes are located on the same straight line. At least two placing plates 4 are provided, and one of the placing plates 4 is slidably connected to the inner wall of the first long through hole 111 of the first bracket 1, and the other placing plate 4 is slidably connected to the inner wall of the first long through hole 111 of the second bracket 2. The two placing plates 4 have the same structure, and placing grooves 41 are provided on the placing plates 4. The positions of the placing grooves 41 on the two placing plates 4 correspond to each other, and the profile X can be conveniently placed in the placing groove 41, greatly improving the efficiency of fixing the profile X.

[0051] Specifically, for the "L"-shaped profile X1, when placing it, after one side of the "L"-shaped profile X1 is placed into the placing groove 41, the other side abuts against the upper surface of the placing plate 4. During chemical plating, when the entire bracket is horizontally transported, the profile X1 can be prevented from slipping off.

[0052] In order to prevent the "L"-shaped profile X1 from slipping off, one more set (two) of placing plates 4 can be provided, and the two placing plates 4 are respectively placed on the first bracket 1 and the second bracket 2. This set of placing plates 4 usually does not place the profile X1. The placing plate 4 is placed above the placing plate 4 on which the profile X1 is placed. Under the action of gravity, the upper placing plate 4 can press the "L"-shaped profile X1 against the lower placing plate 4 to prevent the "L"-shaped profile X1 from slipping off the placing plate 4 during transportation, and the profile X1 on each placing plate 4 can be fixed.

[0053] Multiple sets of placing plates 4 can be provided and freely adjusted according to the number that the first bracket 1 and the second bracket 2 can accommodate and the production requirements. When chemically plating the "L"-shaped profile X1, in order to ensure that the position of the profile X1 is more stable, the two upper placing plates 4 are usually left empty to press the profile X1.

[0054] Specifically, the first bracket 1 (the second bracket 2) includes a first part 11, a second part 12 and a third part 13, wherein the first part 11 and the second part 12 are arranged opposite to each other, the third part 13 is arranged between the first part 11 and the second part 12, and the two ends of the third part 13 are respectively fixedly connected to the first part 11 and the second part 12. A first long through hole 111 is arranged on the first part 11, a second long through hole 121 is arranged on the second part 12, and the second long through hole 121 is arranged in the direction of the opening of the first long through hole 111. One side of the placement plate 4 is slidably connected to the inner wall of the first long through hole 111, and the other side is slidably connected to the inner wall of the second long through hole 121.

[0055] If the length of the connecting rod 3 is not adjustable, then in actual production, the profile X1 with a shorter length will not be able to be received by the two placement plates 4 that are arranged opposite to each other.

[0056] The chemical plating effect of the profile X1 in the part that abuts the placement plate 4 is poor, and this part of the profile X1 is usually cut off, leaving the profile X1 in the middle between the first bracket 1 and the second bracket. When the profile X1 with a longer length is supported by the placement plate 4, the placement plate 4 will abut the middle part of the profile X1, making the chemical plating effect of the middle part of the profile X1 poor, but this part cannot be cut off, otherwise it will damage the overall length of the profile X1.

[0057] Preferably, in one embodiment of the present invention, in order to make the bracket applicable to profiles X1 of different lengths, the connecting rod 3 connecting the first bracket 1 and the second bracket 2 is a telescopic rod, and the length of the telescopic rod is adjustable (that is, the telescopic rod can be fixed at this length after being extended to a certain length). In actual production, the extension length of the telescopic rod is first adjusted according to the length of the target profile X1, and after the telescopic rod is fixed at this length, the profile X1 can be placed.

[0058] If only one placement plate 4 is used to hold the profile X1 down, and if the top placement plate 4 is displaced (eg, bounced up) during transportation, the profile X1 below the placement plate 4 may slip off.

[0059] In order to avoid the above situation, a fixing member 5 is also provided. The fixing member 5 is installed on the first bracket 1 and the second bracket 2, and is used to fix the placement plate 4 to the first bracket 1 or the second bracket 2 (after the profile X1 is placed, the placement plate 4 cannot be displaced relative to the first bracket 1 or the second bracket 2).

[0060] The fixing member 5 can be an iron wire, which passes through the first long through hole 111 or the second long through hole 121 and is arranged above the topmost placement plate 4, and then the iron wire is bent downward, and both ends of the iron wire are located below the first bracket 1 or the second bracket 2. After the iron wire is passed through, the two ends of the iron wire are twisted together, and all the placement plates 4 and the brackets can be fixed together. All the placement plates 4 and the first bracket 1 or the second bracket 2 can be fixed together by four iron wires, which is more convenient than the original need for each profile X1 to be fixed by two iron wires.

[0061] However, fixing the placement plate 4 by threading the wire is still a relatively complicated action, which requires the staff to spend more time.

[0062] Preferably, in an embodiment of the present invention, in order to facilitate the fixing of the placement plate 4 to the first bracket 1 or the second bracket 2, the fixing member 5 is usually configured as a first bolt 51 and a nut 52 or a second bolt.

[0063] When the fixing member 5 is a first bolt 51 and a nut 52, the portion where the placement plate 4 is slidably connected to the first bracket 1 or the second bracket 2 is provided with a through hole 43 matching the outer diameter of the first bolt 51. The extension direction of the through hole 43 is perpendicular to the extension direction of the first long through hole 111 or the second long through hole 121. In order to allow the first bolt 51 to pass through the through hole 43 and fix the placement plate 4 to the first bracket 1 or the second bracket 2, a third long hole 112 is provided on the first portion 11, and a fourth long hole 122 is provided on the second portion 12. The third long hole 112 is perpendicular to the first long through hole 111, the fourth long hole 122 is perpendicular to the second long through hole 121, and the lengths of the first long through hole 111, the second long through hole 121, the third long hole 112 and the fourth long hole 122 are the same. The screw of the first bolt 51 passes through the third long hole 112 and the through hole 43 and then extends to the other side of the first portion 11, the nut 52 is provided on this side and the nut 52 is threadedly connected to the screw. Or the screw rod of the first bolt 51 passes through the fourth long hole 122 and the through hole 43 and extends to the other side of the second part 12, and the nut 52 is arranged on the side and the nut 52 is threadedly connected with the screw rod. After the first bolt 51 and the nut 52 are connected and locked, the placement plate 4 and the first bracket 1 or the second bracket 2 can be fixed, so that the profile X1 on the placement plate 4 is not easy to slip off.

[0064] When the fixing member 5 is a second bolt, a screw hole 72 corresponding to the second bolt needs to be opened on the placement plate 4. The screw hole 72 is arranged on the two end faces of the placement plate 4 in the length extension direction. After the placement plate 4 is arranged in the first long through hole 111 and the second long through hole 121, the two screw holes 72 are respectively located in the first long through hole 111 and the second long through hole 121. At this time, the second bolt is screwed into the screw hole 72 from the other side opening of the first long through hole 111 or the second long through hole 121. During the screwing process, the head of the second bolt will abut against the first part 11 or the second part 12. Under the action of the friction force of the two second bolts at both ends of the placement plate 4 abutting against the first bracket 1 or the second bracket 2, the position of the placement plate 4 is fixed, thereby preventing the profile X1 from slipping off easily.

[0065] If the profile X1 is not initially placed, multiple placement plates 4 are stacked at the bottom of the first bracket 1 or the second bracket 2. When placing the profile X1 on the lower placement plate 4, all the placement plates 4 above it need to be lifted, which makes it extremely difficult to place the profile X1.

[0066] Preferably, in one embodiment of the present invention, in order to facilitate the placement of the profile X1 , a plate 4 is stacked on the top of the first bracket 1 or the second bracket 2 before the profile X1 is placed.

[0067] For convenience, during the stacking, usually only the bottommost placement plate 4 is fixed, so that the placement plate 4 can be quickly put down without loosening the bolts when placing the profile X1. Although the other placement plates 4 are provided with fixing members 5, the fixing members 5 do not fix the placement plates 4 at this time, such as the first bolt 51 or the second bolt is not tightened (the first bolt 51 and the nut 52 at some positions are not shown in the figure, and each placement plate 4 is provided with through holes 43 on both sides, and the through holes 43 are provided with the first bolt 51 and the nut 52 matched therewith).

[0068] At this time, the load on the bottom bolt is larger, and all the placement plates 4 are fixed by these two bolts. In order to shorten the length of the profile X1, the placement plate 4 is usually not set very thick. That is, the second bolts set on the two end faces of the placement plate 4 are bolts with thinner screws. In long-term use, the thinner second bolts may be deformed under the heavy pressure of multiple placement plates 4.

[0069] Preferably, in an embodiment of the present invention, in order to prevent the fixing member 5 from being deformed during use, a first bolt 51 and a nut 52 are usually used to fix the placement plate 4.

[0070] The placement plate 4 provided on the first support 1 needs to be used in conjunction with the placement plate 4 provided on the second support 2 in order to properly place the profile X1. Therefore, the number of placement plates 4 is usually set to an even number (at least two). If an odd number of placement plates 4 is set, one placement plate 4 will not be usable, resulting in waste.

[0071] The width of the placement groove 41 on the placement plate 4 can be set according to the actual production requirements so that the placement plate 4 can place profiles X1 of different sizes. However, it should be noted that for the convenience of producing the placement plate 4, the widths of all the placement grooves 41 on the same placement plate 4 should be the same.

[0072] Furthermore, the widths of the placement grooves 41 of the placement plates 4 at the first height on the first support 1 and the placement plates 4 at the first height on the second support 2 should be the same so that two corresponding placement plates 4 can be paired for use.

[0073] The widths of the placement grooves 41 provided on different placement plates 4 can be different. In actual production, it is often the case that electroless plating is performed on profiles X1 of different specifications on one bracket. At this time, placement plates 4 of different models (with different widths of the placement grooves 41) need to be provided on one bracket, that is, the widths of the placement grooves 41 of some adjacent placement plates 4 are different.

[0074] When performing electroless plating on the "mouth"-shaped profile X2, due to the special structure of this profile X2, after the profile X2 is placed in the placement groove 41, the height of the "mouth"-shaped profile X2 may be less than the height of the placement groove 41. At this time, the "mouth"-shaped profile X2 cannot be pressed by the upper placement plate 4. At this time, the "mouth"-shaped profile X2 cannot be fixed.

[0075] Preferably, in an embodiment of the present invention, in order to enable different profiles X1 and X2 to be fixed during electroless plating so that the electroless plating can proceed normally, the electroless plating bracket is further provided with a baffle 6, a limiting plate 7 and a positioning bolt 8.

[0076] The numbers of the baffle 6, the limiting plate 7 and the positioning bolt 8 correspond to the number of the placement plates 4.

[0077] Specifically, the baffle 6 is an "L"-shaped baffle 6. The baffle 6 includes a horizontal portion 61 and a vertical portion 62. The horizontal portion 61 is fixedly connected to the lower part of the placement plate 4. The "L"-shaped baffle 6 and the placement plate 4 enclose a concave groove 42. The limiting plate 7 is slidably connected to the inner wall of the concave groove 42, and the limiting plate 7 is provided with a first limiting groove 71 that matches the number of the placement grooves 41. When the limiting plate 7 slides in the concave groove 42, the first limiting groove 71 intersects with the placement groove 41, and then the inner walls of the placement groove 41 and the first limiting groove 71 can cooperate to clamp the profile X2.

[0078] Furthermore, the width of the first limiting groove 71 is greater than or equal to the width of the placement groove 41 to prevent the first limiting groove 71 from being too narrow and affecting the profile X1 or X2 that can be placed in the placement groove 41 .

[0079] After the limit plate 7 slides, it is also necessary to fix the limit plate 7 after the limit plate 7 stops. A screw hole 72 is provided on the limit plate 7, and the screw hole 72 is always opposite to the placement plate 4. At this time, the positioning bolt 8 is rotated in the screw hole 72 of the limit plate 7. At this time, after the positioning bolt 8 is tightened, the end face of the screw rod of the bolt will abut against the placement plate 4. On the basis of the threaded connection between the positioning bolt 8 and the limit plate 7, the limit plate 7 will be fixed to the placement plate 4 by the positioning bolt 8, that is, after tightening the positioning bolt 8, the limit plate 7 will not be able to slide relative to the placement plate 4.

[0080] It should be noted that the starting position of the screw hole 72 of the limiting plate 7 should take into account the position of the screw hole 72 after the limiting plate 7 slides, so as to ensure that the screw hole 72 is directly opposite to the placement plate 4 before and after sliding and is not connected to the placement groove 41. If the screw hole 72 is connected to the placement groove 41, when the profile is a "mouth"-shaped profile X2, the screw hole 72 may be located in the cavity of the profile X2, and at this time, the positioning bolt 8 of the profile X2 cannot fix the limiting plate 7 no matter how it rotates.

[0081] Meanwhile, the limiting plate 7 may slip out of the concave groove 42 when sliding in the concave groove 42, such as the limiting plate 7 slipping out from both ends of the concave groove 42 or from the upper opening of the concave groove 42. Placing the limiting plate 7 back into the concave groove 42 will waste a certain amount of time.

[0082] In order to avoid the above situation, a second limiting groove 44 is provided on the placement plate 4, and a limiting protrusion 73 corresponding to the second limiting groove 44 is provided on the limiting plate 7. The cooperation between the second limiting groove 44 and the limiting protrusion 73 can prevent the limiting plate 7 from slipping off the placement plate 4.

[0083] Specifically, the second limiting groove 44 is set as an "L"-shaped second limiting groove 44, which includes a vertical groove 441 and a horizontal groove 442, wherein the vertical groove 441 extends and passes through one side of the placement plate 4, and the vertical groove 441 is perpendicular to the extension direction of the placement plate 4; the horizontal groove 442 extends from one end of the vertical groove 441, and the horizontal groove 442 is parallel to the extension direction of the placement plate 4. The vertical groove 441 passes through the placement plate 4 to form an opening, so that the limiting protrusion 73 can enter the second limiting groove 44, and then slide and connect with the inner wall of the second limiting groove 44.

[0084] When the limiting plate 7 is installed on the placement plate 4, the limiting protrusion 73 set on the limiting plate 7 is first aligned with the opening of the vertical groove 441, and then the limiting plate 7 is put down. The limiting plate 7 falls freely under the action of gravity, and the limiting plate 7 moves to the bottom surface of the vertical groove 441 (one end of the horizontal groove 442) under the limitation of the vertical groove 441. Then the limiting plate 7 is slightly pushed along the horizontal groove 442. At this time, the limiting protrusion 73 moves completely into the horizontal groove 442. The limiting plate 7 cannot slip off in the vertical direction under the limitation of the horizontal groove 442. At the same time, since the horizontal groove 442 does not penetrate the limiting plate 7, the two ends of the horizontal groove 442 limit the limiting plate 7, so that the limiting plate 7 cannot slip off in the horizontal direction when sliding. The limiting plate 7 can only slip off in the vertical direction when the limiting protrusion 73 is aligned with the vertical groove 441, so that the probability of the limiting plate 7 slipping off is greatly reduced.

[0085] It should be noted that different placement plates 4 correspond to different limiting plates 7 .

[0086] For example, as in the present invention Figure 11-12 As shown, the limiting plate 7 applicable to the "L"-shaped profile X1 and the limiting plate 7 applicable to the "M"-shaped profile X2 are different. First, the width of the first limiting groove 71 of the limiting plate 7 applicable to the "L"-shaped profile X1 is slightly larger than the width of the placement groove 41 of the placement plate 4 applicable to the "L"-shaped profile X1, while the width of the first limiting groove 71 of the limiting plate 7 applicable to the "M"-shaped profile X2 is slightly larger than the width of the placement groove 41 of the placement plate 4 applicable to the "M"-shaped profile X2. There is a certain difference in the width of the first limiting groove 71 of the two. Secondly, combined with Figure 6 , since the width of the placement slot 41 of the placement plate 4 for the "L"-shaped profile X1 is relatively narrow, the distance that the limit plate 7 for the "L"-shaped profile X1 needs to slide is relatively short, and the limit plate 7 is almost impossible to hit the first bracket 1 or the second bracket 2 during the sliding process, so that the limit stroke is limited and the profile X1 cannot be fixed. However, since the width of the placement slot 41 of the placement plate 4 for the "mouth"-shaped profile X2 is relatively wide, when the "mouth"-shaped profile X2 is relatively narrow, the distance that the limit plate 7 for the "mouth"-shaped profile X2 needs to slide is relatively long, and the end of the limit plate 7 for the "mouth"-shaped profile X2 may abut against the first bracket 1 or the second bracket 2. At this time, the placement slot 41 should be set slightly away from the first part 11 of the first bracket 1 or the second bracket 2, and the second part 12 of the first bracket 1 or the second bracket 2, and at the same time, the length of the limit plate 7 for the "mouth"-shaped profile X2 should be shortened to avoid the limit plate 7 from not being able to work properly.

[0087] When processing a large number of profiles X, multiple layers of profiles X are stacked together, and there may be some chemical plating solution between the profiles X that is difficult to discharge, which increases the time it takes for the profiles X to enter the next process.

[0088] Preferably, in one embodiment of the present invention, in order to drain the solution in the stacked profiles X as quickly as possible, drainage holes are provided on the limiting plate 7 between adjacent placement slots 41 on the placement plate 4 suitable for the "L"-shaped profile X. After the chemical plating is completed, the solution can be quickly drained by tilting the chemical plating bracket.

[0089] Similarly, after placing the limiting plate 7, in order to prevent the limiting plate 7 from blocking the drainage hole, a long waist hole 74 is provided at the position corresponding to the limiting plate 7 and the drainage hole. The long waist hole 74 is connected to the drainage hole when the limiting plate 7 is in any position to ensure that the solution can be discharged quickly.

[0090] As for the placement plate 4 suitable for the "mouth" shaped profile X2, the "mouth" shaped profile X2 has a long hole, and there is usually a certain gap between the mouth-shaped profile X2 and the placement groove 41 of the placement plate 4 suitable for the "mouth" shaped profile X2. When the chemical plating bracket is tilted, the solution can be quickly discharged from these places.

[0091] Specifically, the operator can freely open the drainage holes according to the shape of the profile X to meet the actual production needs.

[0092] After the profile X is placed, the uppermost placement plate 4 is usually fixed only by the first bolt 51 and the nut 52, so that the fixing operation is simple.

[0093] For some "L"-shaped profiles X1 with curved edges, if the placement plate 4 above the profile X1 directly presses down on the curved edge of the profile X1, the profile X1 is easily crushed. That is, for this type of profile X1, the placement plate 4 above the profile X1 also needs to be fixed by the first bolt 51 and the nut 52 to prevent the profile X1 from deforming. The profile X can still maintain a stable position under the fixation of the limiting plate 7.

[0094] It can be seen that whether the placement plate 4 is fixed by the fixing member 5 needs to be determined according to the type of the profile X in actual production.

[0095] In order to facilitate the chemical plating bracket to discharge the chemical plating solution accumulated in the gap between the profile X, the placement plate 4 and the limiting plate 7, the chemical plating bracket is also provided with a suspension structure 9, which includes a crossbeam 91, two long rods 92 and a cable 93.

[0096] Specifically, a long rod 92 is arranged between the first part 11 and the second part 12 of the first bracket 1, and the two ends of the long rod 92 are fixedly connected to the upper parts of the first part 11 and the second part 12 of the first bracket 1; another long rod 92 is arranged between the first part 11 and the second part 12 of the second bracket 2, and the two ends of the long rod 92 are fixedly connected to the upper parts of the first part 11 and the second part 12 of the second bracket 2; the crossbeam 91 is arranged between the two long rods 92, and the two ends of the crossbeam 91 are fixedly connected to the two long rods 92, and the two ends of the cable 93 are fixedly connected to the crossbeam 91, and the cable 93 is fixedly connected with a hook 931, and the hook 931 deviates from the center of gravity position of the bracket completed by loading the profile.

[0097] When the chemical plating bracket is moved by a lifting device such as an overhead crane, the entire chemical plating bracket will tilt due to the eccentric setting of the hook 931, and the accumulated solution can be discharged more quickly.

[0098] The present invention also discloses a method for loading a chemical plating bracket, the method comprising:

[0099] Step S1): releasing the locking of the fixing member 5 on the lowermost placement plate 4, so that the two placement plates 4 slide from the upper part of the first bracket 1 and the second bracket 2 to the lower part of the first bracket 1 and the second bracket 2;

[0100] Step S2): After the placement plates 4 at the first bracket 1 and the placement plates 4 at the second bracket 2 are aligned, the profile X is placed in the placement slots 41 of the placement plates 4. When the placement slots 41 of the placement plates 4 are filled with the profile X, the placement plates stacked on the first bracket and the second bracket are released again. After the two placement plates 4 slide down from the top of the first bracket 1 and the second bracket 2 and stop, the profile X is placed again.

[0101] Step S3): Move the limiting plate 7 corresponding to each placement plate 4 so that the wall surface of the first limiting groove 71 and the wall surface of the placement groove 41 are both in contact with the profile X, and rotate the positioning bolt 8 to fix the position of the limiting plate 7;

[0102] Step S4): Repeat steps S2 and S3 until all the placement slots 41 on the bracket are filled with profiles X;

[0103] Step S5): The uppermost placement plate 4 is locked by the fixing member 5 so that the positions of all placement plates 4 are fixed.

[0104] By arranging the placement groove 41 on the placement plate 4, a large number of profiles X can be conveniently processed, so that the efficiency of chemical plating of the profiles X is greatly improved.

[0105] When placing the profile X, it should be noted that if the portion of the profile X located above the placement groove 41 does not fit the upper surface of the placement plate 4, but there is a certain gap between the placement plates 4, the operator needs to fix the placement plate 4 above the placement plate 4 on which the profile X is placed through the fixing member 5 to prevent multiple groups of profiles X and the placement plates 4 from squeezing and deforming the profile X below.

[0106] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the present invention.
