[0034] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0037] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0038] To achieve the above-mentioned purpose, the conveying device proposed in the utility model is used to convey the workpiece to be electroplated to the electroplating pool. The conveying device includes a frame, a plurality of hangers and a clamping assembly 100. The plurality of hangers are respectively connected to the frame, and the plurality of hangers are respectively arranged at intervals along the first direction; the clamping assembly 100 includes a clamping member 10 and a clamping member 30. The clamping member 10 and the clamping member 30 are respectively arranged on two adjacent hangers, and the clamping member 10 is clamped to the clamping member 30, so that the distance between the two adjacent hangers is within a preset range.

[0039] The conveying device of the utility model is applied to vertical continuous electroplating equipment. The vertical continuous electroplating equipment continuously moves the workpiece to be electroplated on a vertical line to an electroplating tank for continuous electroplating treatment, so that a uniform electroplating layer is formed on the surface of the workpiece to improve the corrosion resistance and hardness of the workpiece after electroplating.

[0040] Copper plating uniformity is one of the important factors in evaluating the electroplating capacity of vertical continuous electroplating equipment. To ensure electroplating uniformity, the workpieces to be electroplated must be electroplated at the same time and at the same current density; multiple hangers in the same group can complete electroplating at the same time, while hangers in different groups will have different spacings due to errors in the movement of the drive device. As a result, during the electroplating process, there are differences in the current distribution at the edge of the workpiece, which affects the thickness of the electroplated copper at the edge of the board, causing the copper thickness values ​​on the surface of the workpieces clamped by hangers in different groups to fluctuate, thus affecting the uniformity of electroplating.

[0041] In order to solve the above problems, in the utility model, the frame of the conveying device serves as the framework of the entire device, and provides installation positions for multiple hangers so that the hangers can move stably and reduce their shaking; the hangers are used to clamp or carry the workpiece to be electroplated, so that the workpiece to be electroplated can smoothly enter and exit the electroplating tank; the clamping assembly 100 is used to make the distance between two adjacent hangers within a preset range. The clamping assembly 100 includes two parts, a clamping member 10 and a clamping member 30. The clamping member 10 and the clamping member 30 are clamped to maintain the connection stability between the two. Compared with other connection methods, the clamping member is flexible and can make multiple hangers adapt to various working conditions; the clamping member 10 and the clamping member 30 can also make the distance between adjacent hangers of different groups consistent, so that the workpieces clamped by them can be electroplated at the same time and the same current density to improve the uniformity of electroplating.

[0042] In the present invention, the conveying device may further include a driving assembly, which may be used as a power source and connected to the racks by transmission, thereby driving the movement of the plurality of racks. The driving assembly mentioned here may be a chain structure, which drives the racks to move at a uniform speed in the electroplating bath by chain transmission. However, due to the different timing and tightness of the chain engagement, the spacing between racks in different groups may be inconsistent, so the present invention provides an elastic clamping assembly to maintain the spacing between racks in different groups.

[0043] The first direction, the second direction and the third direction mentioned in this article can be understood as the length direction, the height direction and the width direction of the rack; the connection between the bracket and the rack can be screwed, and the connection between the snap assembly 100 and the bracket can also be screwed, or other detachable connection methods, which are not limited here.

[0044] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the engaging assembly 100 further includes a rotating shaft 50 , which is passed through a bracket where the engaging member 10 is located, and the engaging member 10 is rotatably connected to the rotating shaft 50 .

[0045] In this embodiment, the connection between the rotating shaft 50 and the bracket may be a screw connection or a plug connection, or may be other connection methods that can maintain the stability of the connection between the two, which is not limited here.

[0046] The engaging member 10 may be provided with an installation hole for installing the rotating shaft 50. The rotating shaft 50 passes through the engaging member 10 and the bracket in sequence along the third direction and is screwed to the bracket to maintain its stability. The engaging member 10 is rotatably connected to the rotating shaft 50, that is, the engaging member 10 takes the rotating shaft 50 as the rotation center and can rotate around the rotating shaft 50.

[0047] It can be known that when the engaging member 10 and the connecting member 30 need to be connected, the driving assembly can drive the bracket connected to the rotating shaft 50 to move, and the engaging member 10 moves accordingly, and when it moves to the connecting member 30, it is connected with the connecting member 30. The specific structure of the engaging member 10 and the connecting member 30 can be a structure of matching a groove and a protrusion, or can be an annular connection, or can be other connecting structures, which are not limited here.

[0048] Reference Figure 1 and Figure 2 In one embodiment of the utility model, further, the engaging member 10 includes a plate body 11 and a hook head 13, the plate body 11 rotates around the rotating axis 50; the hook head 13 is arranged on a side of the plate body 11 close to the engaging member 30 and extends along the second direction; the hook head 13 moves along the setting direction of the engaging member 30 to engage with the engaging member 30.

[0049] In this embodiment, the plate body 11 serves as the main part of the snap-fitting part 10, and is used to provide an installation position and support for the hook head part 13. The plate body 11 is extended along a first direction, which is consistent with the setting direction of the hanger, so as to facilitate connection with the snap-fitting part 30; the hook head part 13, as the part connected to the snap-fitting part 30, also serves as a limit for the snap-fitting part 30, further maintaining the connection stability between the snap-fitting part 10 and the snap-fitting part 30, thereby maintaining the distance between two adjacent hangers, further improving the uniformity of electroplating, and reducing production costs.

[0050] It can be known that the hook portion 13 is arranged along the second direction, and is arranged perpendicularly to the plate body 11 arranged along the first direction. The connection between the plate body 11 and the hook portion 13 forms a clamping position, and the clamping member 30 abuts against the clamping position. When the clamping member 10 and the clamping member 30 need to be clamped, the driving assembly can drive the hanger connected to the rotating shaft 50 to move, and the clamping member 10 moves accordingly. When it moves to the clamping member 30, the hook portion 13 is clamped with the clamping member 30.

[0051] Reference Figure 1 and Figure 2In one embodiment of the utility model, further, the clamping assembly 100 also includes an insulating plate 70, which is arranged on the bracket where the clamping member 30 is located, and the clamping member 30 is sequentially penetrated through the insulating plate 70 and the bracket along the third direction; the clamping member 30 is inclined in the direction toward the hook head 13, the hook head 13 moves along the clamping member 30, and the plate body 11 rotates so that the hook head 13 is clamped with the clamping member 30.

[0052] In this embodiment, the insulating plate 70 is used to prevent the current from being conducted to the area that does not need to be electroplated, so as to ensure the accuracy and safety of the work to be electroplated during the electroplating process. The connection between the insulating plate 70 and the rack can be a detachable connection such as a screw connection or a clamp connection, or a fixed connection such as a welding connection, or a connection method that maintains a stable connection between the insulating plate 70 and the rack, which is not limited here.

[0053] It can be known that the clamping member 30 can be tilted in the direction toward the hook head portion 13. It can be understood that the clamping member 30 provides the hook head portion 13 with a moving track, and the moving track is tilted. When the clamping member 10 and the clamping member 30 need to be clamped, the driving assembly can drive the hanger connected to the rotating shaft 50 to move. When the hook head portion 13 moves to the clamping member 30, it will move along the moving track. At this time, the clamping member 10 will rotate around the rotating shaft 50 in the direction away from the clamping member 30. When the clamping member 30 leaves the tail end of the moving track, the force generated by the clamping member 30 on the clamping member 10 disappears. At this time, the clamping member 10 will gradually return to its original position around the rotating shaft 50, and the hook head portion 13 is clamped with the clamping member 30 to complete the installation between the clamping member 10 and the clamping member 30 and maintain a stable connection.

[0054] It can be understood that the connection method between the above-mentioned snap-fitting part 10 and the snap-fitting part 30 is simple to operate, and the two are in a stable state after being snapped together. The two have simple structures and low production costs, and the spacing between two adjacent hangers is maintained, thereby further improving the uniformity of electroplating.

[0055] Reference Figure 1 and Figure 2 In one embodiment of the utility model, the clamping member 30 includes a nut 31 and a first sleeve 33. The nut 31 is inserted into the insulating plate 70 and the bracket along the third direction. The first sleeve 33 is sleeved on the outer periphery of the nut 31 and is inclined in the direction toward the hook head 13. The hook head 13 moves along the setting direction of the first sleeve 33 to be clamped with the first sleeve 33.

[0056] In this embodiment, the nut 31 is used to screw the insulating plate 70 and the bracket to maintain stability between the insulating plate 70 and the bracket. At the same time, the nut 31 also provides an installation position for the first sleeve 33, so that the overall setting of the clamping member 30 is compact and the space utilization is improved; the first sleeve 33 is used to provide a movement track for the hook head 13.

[0057] It can be known that the material of the first sleeve 33 can be a flexible material such as silicone, rubber, etc., so that when the hook head 13 moves along the first sleeve 33, the loss and friction of the hook head 13 can be reduced; the movement process of the hook head 13 along the motion track can be referred to above, and will not be repeated here.

[0058] By setting the first sleeve 33, the connection between the snap-fitting part 10 and the snap-fitting part 30 can be easily operated, and the two are in a stable state after being snapped together, with low production cost, maintaining the distance between two adjacent hangers, and improving the uniformity of electroplating; in other embodiments of the utility model, the nut 31 can also be set to other rod-shaped structures, which is not limited here.

[0059] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the first sleeve 33 is conically arranged, and the first sleeve 33 is located at an end of the nut 31 away from the bracket.

[0060] In this embodiment, the first sleeve 33 is arranged in a conical shape, so that the first sleeve 33 can adapt to the engaging parts 10 of different shapes, and also makes the rotation of the engaging part 10 simpler, without adding additional structure to facilitate the clamping connection between the two, thereby reducing production costs; the setting position of the first sleeve 33 corresponds to the position of the engaging part 10, which facilitates the connection between the engaging part 10 and the clamping part 30, and also makes the clamping connection between the two tighter, thereby improving the stability and quality of electroplating.

[0061] Reference Figure 1 , Figure 2 and Figure 4 In one embodiment of the utility model, the engaging member 10 further includes an abutting portion 15 and a limiting member 17 arranged on the abutting portion 15. The abutting portion 15 is arranged on one side of the plate body 11 close to the rotating shaft 50 and is inclined toward the direction close to the engaging member 30. The limiting member 17 abuts against one of the two adjacent hangers.

[0062] In this embodiment, the abutment portion 15 is used to cooperate with the unlocking component 300 to separate the engaging member 10 and the connecting member 30 and enter the next process. The limit member 17 is used to control the rotation angle of the engaging member 10, so as to facilitate the re-engagement between the engaging member 10 and the connecting member 30 after entering the next process.

[0063] It can be known that the abutment portion 15 is arranged on the side of the plate body 11 away from the hook head portion 13, and its length is greater than the length of the hook head portion 13, which is more convenient for cooperation with the unlocking component 300 and reduces the possibility of collision between the hook head portion 13 and the unlocking component 300. The structure that is connected to different components is arranged on one component, so that the function of the locking part 10 itself is increased, and the overall structure is more compact, which reduces the production cost. At the same time, it is also convenient for the separation of the locking part 10 and the locking part 30 to smoothly enter the next process in sequence.

[0064] Reference Figure 3 and Figure 4 In one embodiment of the utility model, the conveying device also includes an unlocking component 300, the electroplating pool is provided with a discharge end along the first direction, the unlocking component 300 includes a mounting plate 301 and an unlocking member 303, the mounting plate 301 is arranged at the discharge end; the unlocking member 303 is arranged on the mounting plate 301, the height of the unlocking member 303 changes along the first direction, the abutting portion 15 abuts against the unlocking member 303, and moves along the setting direction of the unlocking member 303 to separate the hook head portion 13 and the clamping member 30.

[0065] In this embodiment, the mounting plate 301 is used for connecting the discharge end to maintain the overall stability of the unlocking assembly 300. The mounting plate 301 can be set in an L shape, which can enhance the strength of the mounting plate 301 and make the connection with the discharge end more stable. The unlocking piece 303 and the mounting plate 301 can be screwed to facilitate disassembly and maintenance.

[0066] When the abutment portion 15 abuts against the unlocking member 303, when the driving device drives the hanger to move in the first direction, the abutment portion 15 can move along the surface of the unlocking member 303. Since the height of the unlocking member 303 changes along the first direction, the abutment portion 15 tends to move toward the direction close to the rotation axis 50, so that the plate body 11 rotates around the rotation axis 50 to separate the hook head 13 from the clamping member 30, so that the two adjacent hangers are in a separated state, so that they can enter the next process in turn. After entering the next process, the hook head 13 and the first sleeve 33 are re-clamped, and the cycle is repeated.

[0067] Reference Figure 3 and Figure 4 In one embodiment of the utility model, the unlocking member 303 includes a first guide portion 305, a second guide portion 307 and a third guide portion 309 connected in sequence, the height of the first guide portion 305 gradually increases along the first direction, the height of the second guide portion 307 remains unchanged along the first direction, and the height of the third guide portion 309 gradually decreases along the first direction; the abutting portion 15 abuts against the first guide portion 305 and moves along the first guide portion 305. When the abutting portion 15 moves to the second guide portion 307, the plate body 11 rotates around the rotating axis 50 to separate the hook portion 13 from the clamping member 30.

[0068] In this embodiment, the height of the first guide portion 305 gradually increases along the first direction, the height of the second guide portion 307 remains unchanged along the first direction, and the height of the third guide portion 309 gradually decreases along the first direction, that is, the unlocking member 303 is arranged in a shuttle shape; such an arrangement makes the abutting portion 15 at the first guide portion 305 have a tendency to move in the direction of the rotation axis 50, so that the plate body 11 has a tendency to rotate around the rotation axis 50; when the abutting portion 15 moves to the second guide portion 307, the plate body 11 has rotated to a certain angle around the rotation axis 50, because the limit member 17 abuts against the hanger, the rotation angle of the plate body 11 is within a preset range, and the hook head 13 is separated from the clamping member 30 at this time; when moving to the third guide portion 309, the height of the unlocking member 303 is slowly decreasing, so the abutting portion 15 moves along it, providing a force for the plate body 11 to move toward the third guide portion 309, and at this time the plate body 11 slowly rotates around the rotation axis 50 to the original position, and enters the next process.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application is described in detail with reference to the above embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
