[0038] 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.

[0039] 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.

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.

[0041] 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.

[0042] The utility model proposes a conveying device for conveying a workpiece to be electroplated into an electroplating pool. The conveying device includes a frame, an elastic clamping assembly 100 and a plurality of hangers. The plurality of hangers are respectively connected to the frame, and the plurality of hangers are respectively arranged at intervals along a first direction; two adjacent hangers are connected by the elastic clamping assembly 100 so that the distance between the two adjacent hangers is within a preset range.

[0043] 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.

[0044] 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 multiple hangers in different groups will have different spacings between hangers 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.

[0045] 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 elastic clamping component 100 is used to make the distance between two adjacent hangers within a preset range. It has a simple structure and the component itself is elastic, and the clamping stability of the component will not be affected by the collision of the internal structure of the component. In this way, the distance between adjacent hangers of different groups can be 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.

[0046] 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 100 to maintain the spacing between racks in different groups.

[0047] 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 a screw connection, and the connection between the elastic clamping assembly 100 and the bracket can also be a screw connection, or other detachable connection methods, which are not limited here.

[0048] Reference Figure 1 and Figure 2In one embodiment of the present invention, the elastic clamping assembly 100 includes a clamping structure 10 and a snap-fit ​​structure 30. The clamping structure 10 and the snap-fit ​​structure 30 are respectively arranged on two adjacent hangers, and the clamping structure 10 and the snap-fit ​​structure 30 are elastically snap-fitted.

[0049] In this embodiment, the elastic clamping assembly 100 includes two parts, namely a clamping structure 10 and a snap-fit ​​structure 30. The clamping structure 10 and the snap-fit ​​structure 30 are respectively arranged on two adjacent hangers in different groups. The connection between the two is an elastic snap connection, which facilitates quick connection between the two and can maintain the connection between the two by adaptively adjusting errors.

[0050] This arrangement has a simple structure and a simple connection between the two. At the same time, no error will be generated due to collision between the two, thereby improving electroplating uniformity and reducing production costs.

[0051] Reference Figure 1 and Figure 2 In one embodiment of the utility model, further, the clamping structure 10 includes a first mounting plate 11, a clamping member 13 and at least two elastic members 15, the first mounting plate 11 is arranged on one of the two adjacent hangers, and the first mounting plate 11 has a first end 111 and a second end 113 that are oppositely arranged along the second direction; the clamping member 13 is hinged to the first mounting plate 11, and the clamping member 13 has a first end 131 and a second end 133 that are oppositely arranged along the second direction; one of the elastic members 15 elastically connects the first end 111 and the first end 131, and the other elastic member 15 elastically connects the second end 113 and the second end 133.

[0052] In this embodiment, the first mounting plate 11 is used to be installed with the hanger to maintain the overall stability of the clamping structure 10, the clamping member 13 is used to clamp with the snap-fit ​​structure 30 to ensure the clamping stability of the clamping structure 10 and the snap-fit ​​structure 30, and the elastic member 15 is used to absorb impact to further enhance the clamping stability.

[0053] The clamping member 13 and the first mounting plate 11 are hinged, that is, the clamping member 13 rotates around an axis, so that the clamping member 13 can move flexibly and can have a stable connection relationship with the clamping structure 30. An elastic member 15 connects the first end 111 of the first mounting plate 11 and the first end 131 of the clamping member 13, and another elastic member 15 connects the second end 113 of the first mounting plate 11 and the second end 133 of the clamping member 13; when the clamping structure 30 abuts against the clamping member 13 and moves toward the inside thereof, the elastic member 15 will undergo elastic deformation to drive the clamping member 13 to rotate in a direction away from the clamping structure 30, and when the clamping structure 30 enters into the inside of the clamping member 13, the elastic member 15 will gradually return to its original state, so that the clamping member 13 and the clamping structure 30 are completely clamped. Therefore, the elastic member 15 can absorb vibrations or shocks caused by differences in workpiece size or during operation, thereby further enhancing the clamping stability between the two, that is, making the spacing between adjacent racks consistent, further improving electroplating uniformity, and reducing production costs.

[0054] It can be known that in other embodiments of the present invention, the number of elastic members 15 can be increased or decreased according to different requirements of the hangers to maintain the spacing between hangers of different sizes; the clamping member 13 and the first mounting plate 11 are both provided with mounting members for the elastic member 15 to install so as to maintain its installation stability. The elastic member 15 can be a spring or other elastic member 15 that can undergo elastic deformation.

[0055] Reference Figure 1 and Figure 2 In one embodiment of the utility model, further, the clamping structure 10 also includes a hinge shaft 17, the hinge shaft 17 is penetrated through the first mounting plate 11 along the third direction, and the clamping member 13 includes a first clamping portion 135 and a second clamping portion 137 connected to each other, the first clamping portion 135 and the second clamping portion 137 are respectively hinged to the hinge shaft 17 to form a clamping groove 139; the clamping structure 30 is clamped to the clamping groove 139.

[0056] In this embodiment, the first clamping portion 135 and the second clamping portion 137 both rotate around the hinge shaft 17 to maintain a stable connection between the clamping member 13 and the first mounting plate 11, and also enable the first clamping portion 135 and the second clamping portion 137 to rotate stably; the clamping groove 139 formed by the first clamping portion 135 and the second clamping portion 137 is used to clamp the clamping structure 30, and the two elastic members 15 are respectively connected to the first clamping portion 135 and the second clamping portion 137. When the clamping structure 30 moves to the notch of the clamping groove 139, the driving component drives it to move into the groove of the clamping groove 139. At this time, the clamping structure 30 is clamped to the notch. The force will be transmitted to the elastic member 15, causing the elastic member 15 to undergo elastic deformation, so that the two elastic members 15 simultaneously drive the first clamping portion 135 and the second clamping portion 137 to rotate, and the clamping structure 30 smoothly enters the clamping groove 139. At this time, the clamping structure 30 has no force on the clamping groove 139, and the elastic member 15 returns to its original state, and the first clamping portion 135 and the second clamping portion 137 return to their original positions, which play a role of clamping and limiting the clamping structure 30, thereby completing the clamping connection between the two, and the clamping connection between the two is very stable, that is, the spacing between the two adjacent hangers is maintained, further improving the uniformity of electroplating and reducing production costs.

[0057] In summary, the clamping structure 10 has a simple overall structure, low production cost, and high connection stability, and can improve the overall reliability of the conveying device.

[0058] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the clamping member 13 is arranged in an Ω shape.

[0059] In this embodiment, the Ω-shaped clamping member 13 can adapt to a variety of different shapes of the clamping structure 30, and it has a structure with an approximately circular cross-section, which can enhance the clamping stability; at the same time, the Ω-shaped clamping member 13 can better disperse the clamping force and reduce the sliding or deformation of the clamping structure 30 during the clamping process, thereby improving the stability and quality of electroplating.

[0060] Of course, in other embodiments of the present invention, the clamping member 13 may also be configured as other shapes that can be tightly engaged with the engaging structure 30 , which is not limited here.

[0061] Reference Figure 1 and Figure 2 In one embodiment of the utility model, the snap-fit ​​structure 30 includes a second mounting plate 31 and a snap-fit ​​member 33 protruding from the second mounting plate 31; the snap-fit ​​member 33 includes a connecting portion 335 and a snap-fit ​​portion 331 connected to each other, the connecting portion 335 is connected to the second mounting plate 31, and the snap-fit ​​portion 331 is snap-fitted to the clamping groove 139.

[0062] In this embodiment, the second mounting plate 31 is installed with another hanger to maintain the overall stability of the snap-fit ​​structure 30 , and the snap-fit ​​member 33 is used to snap-fit ​​with the clamping member 13 to maintain the snap-fit ​​stability of the snap-fit ​​structure 30 and the clamping structure 10 .

[0063] The connecting portion 335 of the clamping member 33 is connected to the second connecting plate to maintain the stability of the clamping member 33. The clamping portion 331 is clamped in the clamping groove 139. The clamping portion 331 and the connecting portion 335 can be an integrally formed structure, or can be connected by screw connection, welding or other connection methods, which are not limited here.

[0064] It can be known that the snap-fit ​​structure 30 can be an integrally formed structure, and the second mounting plate 31 and the connecting portion 335 can also be connected by screwing, welding or other connection methods; the snap-fit ​​portion 331 is snapped into the clamping groove 139 to maintain the stability of the connection between the snap-fit ​​portion 331 and the clamping groove 139, so as to maintain the spacing between two adjacent hangers, improve the uniformity of electroplating, and reduce production costs.

[0065] Reference Figure 1 and Figure 2 In one embodiment of the utility model, further, the clamping portion 331 has two inclined surfaces 333 arranged opposite to each other. When the clamping portion 331 is clamped into the clamping groove 139, the two inclined surfaces 333 abut against the notch of the clamping groove 139, and the two elastic members 15 are deformed to make the clamping member 13 move in a direction away from the clamping portion 331, so that the clamping portion 331 clamps the clamping groove 139; the clamping member 13 is provided with a limiting end 138, and the clamping portion 331 is provided with a limiting groove 3311, which is located between the connecting portion 335 and the inclined surface 333, and the limiting end 138 clamps the limiting groove 3311.

[0066] In this embodiment, the two inclined surfaces 333 of the clamping portion 331 can abut against the notch of the clamping groove 139, which can generate a greater force on the notch of the clamping groove 139 than the plane, so that the clamping portion 331 can enter the clamping groove 139; at the same time, the loss of the clamping member 13 of the inclined surface 333 is also small; the elastic member 15 deforms to drive the first clamping portion 135 and the second clamping portion 137 to move, and the clamping portion 331 finally abuts against the bottom of the clamping groove 139, and the elastic member 15 also rebounds to its original position, so that the first clamping portion 135 and the second clamping portion 137 also return to their original positions, which plays a role of clamping and limiting the clamping portion 331.

[0067] It can be known that the connecting portion 335 has an inwardly recessed arc surface, and the clamping portion 331 also has an outwardly arranged arc surface, thereby reducing the production cost of the clamping member 33; a limiting groove 3311 is formed between the two arc surfaces, and the first clamping portion 135 and the second clamping portion 137 are both provided with limiting ends 138, and the limiting ends 138 are clamped in the limiting groove 3311, so that the clamping member 13 forms a double limit for the clamping member 33 to ensure the clamping stability between the clamping structure 30 and the clamping structure 10, so as to maintain the spacing between the two adjacent hangers, further improve the uniformity of electroplating, and reduce the production cost.

[0068] Reference Figures 1 to 4 In one embodiment of the utility model, the conveying device also includes an unlocking component 500 and an abutting component 700. The electroplating pool is provided with a discharge end along the first direction, and the unlocking component 500 is arranged at the discharge end; the unlocking component 500 and the abutting component 700 are used to separate two adjacent hangers.

[0069] In this embodiment, the unlocking component 500 is arranged at the discharge end of the electroplating pool, and is used to separate the clamping member 13 and the snap-in member 33 so as to separate the two adjacent hangers and enter the next electroplating process in sequence; the abutment component 700 is used to cooperate with the unlocking component 500 to separate the clamping member 13 and the snap-in member 33.

[0070] Reference Figures 1 to 4 In one embodiment of the utility model, further, the abutment assembly 700 includes a first abutment member 710 and a second abutment member 730, the first abutment member 710 is arranged on the first clamping portion 135, the second abutment member 730 is arranged on the second clamping portion 137, and the first abutment member 710 and the second abutment member 730 are both extended along the third direction; the unlocking assembly 500 includes a third mounting plate 510 and an unlocking member 530, the third mounting plate 510 is arranged at the discharge end; the unlocking member 530 is arranged on the third mounting plate 510, the height of the unlocking member 530 changes along the first direction, the first abutment member 710 and the second abutment member 730 respectively abut on both sides of the unlocking member 530, and move along the first direction to separate the first clamping portion 135 and the second clamping portion 137 from the locking structure 30.

[0071] In this embodiment, the first abutment member 710 is arranged on the first clamping portion 135, and the second abutment member 730 is arranged at the second clamping portion 137 and extends out of the clamping portion to respectively abut against the two ends of the unlocking assembly 500 and move along its setting direction; the third mounting plate 510 is used for connecting the discharge end to maintain the overall stability of the unlocking assembly 500. The third mounting plate 510 can be arranged in an L shape, which can enhance the strength of the third mounting plate 510 and make the connection with the discharge end more stable; the unlocking member 530 and the third mounting plate 510 can be screwed to facilitate disassembly and assembly.

[0072] It can be known that since the height of the unlocking member 530 changes along the first direction, the first abutment member 710 and the second abutment member 730 tend to move toward the first clamping portion 135 and the second clamping portion 137, causing the elastic member 15 to produce elastic deformation to separate the first clamping portion 135 and the second clamping portion 137 from the snap-in member 33, 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 snap-in member 33 is clamped in the clamping groove 139 again, and the cycle is repeated.

[0073] Reference Figures 1 to 4 In one embodiment of the utility model, further, the unlocking member 530 includes a first guide portion 531, a second guide portion 533 and a third guide portion 535 which are connected in sequence, the height of the first guide portion 531 gradually increases along the first direction, the height of the second guide portion 533 remains unchanged along the first direction, and the height of the third guide portion 535 gradually decreases along the first direction; the first abutting member 710 and the second abutting member 730 respectively abut on two opposite sides of the first guide portion 531, and when the first abutting member 710 and the second abutting member 730 move to the second guide portion 533, the first clamping portion 135 and the second clamping portion 137 are both separated from the locking structure 30.

[0074] In this embodiment, the height of the first guide portion 531 gradually increases along the first direction, the height of the second guide portion 533 remains unchanged along the first direction, and the height of the third guide portion 535 gradually decreases along the first direction, that is, the unlocking member 530 is arranged in a shuttle shape;

[0075] Such arrangement makes the first abutment 710 and the second abutment 730 tend to move toward the clamping member 13 at the first guide portion 531, and the force generated by them will be transmitted to the elastic member 15, causing the elastic member 15 to elastically deform; when the first abutment 710 and the second abutment 730 move to the second guide portion 533, the elastic member 15 is always in an elastically deformed state, so the first clamping portion 135 and the second clamping portion 137 are always in an open state, and when moving to the third guide portion 535, its height is slowly decreasing, so the height difference between the first abutment 710 and the second abutment 730 is gradually restored to the original data, and the elastic member 15 rebounds to its original position, so that the first clamping portion 135 and the second clamping portion 137 are also gradually restored to their original positions, thereby entering the next process in a closed state.
