Description
Technical Field

At present, electroplating is widely applied to the fields of industry, traffic, electronic devices and various articles for daily use, and the principle of the electroplating is that in an electroplating pool with adjusted main components as required plating layer ions, a cathode and an anode are electrified to generate electrode reaction, so that metal ions in electroplating solution are reduced into metal simple substances through cations under the action of an electric field, and the metal simple substances are deposited on the surface of a workpiece to be plated to form a plating layer on the surface of the workpiece to be plated. Generally, in horizontal electroplating, a workpiece to be plated is clamped by a clamp and horizontally runs in an electroplating bath, and the workpiece to be plated is connected with a cathode of an external power supply through the clamp so as to be contacted with the workpiece to be plated for conduction; anode materials are arranged on the upper side and the lower side of the workpiece to be plated at intervals respectively, the anode materials are connected with the anode to electrically introduce the anode into electroplating solution, so that the anode and the anode form an electric field, and the electroplating solution in the electroplating bath is subjected to electroplating reaction on the surface of the workpiece to be plated to generate various film layers, so that the electroplating effect is realized. Factors affecting the electroplating effect are many, such as electroplating solution, temperature, current density, power supply stability and the like, wherein, ensuring stable power supply is related to the quality of plated products.
In the related art, in the electroplating equipment, the power connection mode mainly runs in a specific track directly through a power connection part on the clamp, and the power connection part is usually provided with a spring so as to ensure that the contact conduction is sufficient and adapt to the situation of contact surface change or excessively large and small distance. However, the above method has some problems, for example, the direction of the spring force is perpendicular to the moving direction of the clamp, so that the clamp is unevenly stressed at the starting point and the ending point of the contact surface with the clamp power connection mechanism in the moving direction, which causes the impact of the structure at the butt joint and easily causes the spring to drive the relevant mechanism to jump, thus affecting the stability of power supply.
In addition to the above manner, the hanger slides on the rail by means of gravity, and can keep being electrified without a spring; however, the hanger often uses a chain transmission, and if the tensioning degree of the chain is not good, the condition that the hanger cannot contact with the track is easily caused, so that normal conduction is influenced.

Detailed Description
The technical solutions of the present application will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 to 8, in some embodiments of the present application, an electrical connection device 100 is provided, and the electrical connection device 100 can be applied to a plating fixture 200 of a plating apparatus to supply power to a workpiece to be plated held by the plating fixture 200. In addition, the power receiving apparatus 100 may also be applied to other devices, scenes, and working conditions, which are not limited in this embodiment.
As shown in fig. 1 to 8, in some embodiments, the power receiving apparatus 100 includes a conductive rack 110, a plurality of conductive modules 120, and a conductive slider 220. The conductive module 120 includes a first conductive clamping block 121 and a second conductive clamping block 122, and both the first conductive clamping block 121 and the second conductive clamping block 122 are rotatably connected to the conductive bracket 110. Alternatively, the rotation may be realized by using a shaft connection, a pin connection, or the like, so that the first conductive clamping block 121 may rotate relative to the conductive bracket 110, and the second conductive clamping block 122 may rotate relative to the conductive bracket 110, thereby facilitating adjustment of the relative position, the relative angle, and the like of the first conductive clamping block 121 and the second conductive clamping block 122.
The first conductive block 121 has a first contact surface 1211, the second conductive block 122 has a second contact surface 1221, and the first contact surface 1211 and the second contact surface 1221 are disposed opposite to each other, so that an accommodating space M can be formed between the first contact surface 1211 and the second contact surface 1221, and the accommodating spaces M of the plurality of conductive modules 120 are sequentially disposed along a first direction to form a channel for accommodating the conductive slider 220. The conductive slider 220 is movably disposed in the channel, and the conductive slider 220 is used for mechanically and electrically connecting with the plating jig 200. Based on this, on one hand, when the conductive slider 220 moves in the channel along the first direction, the workpiece to be electroplated can be carried by the electroplating fixture 200 to move in the electroplating bath, and on the other hand, the electrical connection between the conductive module 120 and the conductive slider 220 can be realized, so as to supply power to the workpiece to be electroplated in the electroplating process.
Further, the first contact surface 1211 and the second contact surface 1221 have a tendency to press the two opposite sides of the conductive slider 220, so as to ensure that the first conductive clamping block 121 and the second conductive clamping block 122 can clamp the conductive slider 220 from the two opposite sides, thereby ensuring good contact. The pressing direction of the first contact surface 1211 to one side of the conductive slider 220 is acute to the first direction, and the pressing direction of the second contact surface 1221 to the other side of the conductive slider 220 is acute to the first direction.
Based on the above arrangement, the power connection apparatus 100 provided in the embodiment of the invention includes the conductive bracket 110, the plurality of conductive modules 120, and the conductive slider 220 for mechanically and electrically connecting the electroplating fixture 200, wherein the accommodating spaces M of the plurality of conductive modules 120 are sequentially arranged along the first direction, so as to form a channel, and the conductive slider 220 can move in the channel and can be constantly electrically connected in the moving process, so that the electroplating fixture 200 and the workpiece to be electroplated carried by the electroplating fixture 200 can move in the electroplating bath by moving the conductive slider 220 along the channel, and the conductive bracket 110, the conductive modules 120, the conductive slider 220, and the electroplating fixture 200 can be electrically connected, thereby electroplating the workpiece.
The first conductive clamping block 121 contacts with one side of the conductive slider 220 through the first contact surface 1211, and the second conductive clamping block 122 contacts with the other side of the conductive slider 220 through the second contact surface 1221, so that the conductive slider 220 is squeezed from the opposite sides, and good contact between the conductive slider 220 and the conductive module 120 is ensured, thereby preventing the occurrence of a virtual connection to influence the electroplating process.
Moreover, the pressing direction of the first contact surface 1211 to one side of the conductive slider 220 is acute angle to the first direction, and the pressing direction of the second contact surface 1221 to the other side of the conductive slider 220 is acute angle to the first direction, so that the respective pressing forces of the first contact surface 1211 and the second contact surface 1221 to the conductive slider 220 can be decomposed into a driving component force along the first direction and a pressing component force perpendicular to the first direction, and the driving component force is beneficial to promoting the conductive slider 220 to move along the first direction, so that the impact of the two conductive clamping blocks on the conductive slider 220 can be prevented, the problem of bouncing of the conductive slider 220 can be effectively solved, and meanwhile, the pressing is beneficial to pressing the conductive slider 220 from the opposite sides by the first conductive clamping block 121 and the second conductive clamping block 122, so that good contact and conductivity can be realized.
As shown in fig. 3 or 4, in some embodiments, an extending direction of a vertical line from any point on the first contact surface 1211 to the rotation axis of the first conductive clip 121 forms an obtuse angle with the first direction, i.e., a first obtuse angle. It should be noted that, since the first conductive clip 121 and the conductive slider 220 are in a surface contact state, a perpendicular connection line from any point on the first contact surface 1211 to the rotation axis of the first conductive clip 121 forms a first acute angle with the first contact surface 1211, and the first contact surface 1211 is perpendicular to the first direction, so that an angle increased by 90 ° based on the first acute angle is the first obtuse angle.
Similarly, the extending direction of the vertical line from any point on the second contact surface 1221 to the rotation axis of the second conductive clamping block 122 forms an obtuse angle with the first direction, i.e., a second obtuse angle. It should be noted that, because the second conductive clip 122 is in a surface contact state with the conductive slider 220, a vertical connection line from any point on the second contact surface 1221 to the rotation axis of the second conductive clip 122 forms a second acute angle with the second contact surface 1221, and the second contact surface 1221 is perpendicular to the first direction, so that the second obtuse angle is obtained by adding 90 ° to the second acute angle.
Based on the above arrangement, as shown in fig. 8, as can be seen from the force analysis of the conductive slider 220 in the vertical plane, the conductive slider 220 is subjected to a driving force F1 along the first direction, and under the driving action of the driving force F1, the conductive slider 220 can move along the first direction in the channel; an acute angle is formed between the acting force F2 of the first conductive clip 121 on one side of the conductive slider 220 and the driving force F1, and an acute angle is formed between the acting force F3 of the second conductive clip 122 on the other side of the conductive slider 220 and the driving force F1.
Wherein the force F2 may resolve a downward vertical component F2Y and a horizontal separation F2X in the first direction, and the force F3 may resolve an upward vertical component F3Y and a horizontal component F3X in the first direction. Therefore, both F2X and F3X are in the same direction as the driving force F1, so that the two horizontal component forces and the driving force are used for jointly driving the conductive slider 220 to move along the first direction, thereby facilitating the conductive slider 220 to stably move in the channel without generating impact jump; the F2Y faces one side of the conductive slider 220, and the F3Y faces the other side of the conductive slider 220, so that the conductive slider 220 can be pressed from the opposite sides, which is beneficial to maintaining good power transmission.
As shown in fig. 3 or 4, in some embodiments, the bayonet of the receiving space M is gradually enlarged in the first direction. Based on this, the first contact surface 1211 and the second contact surface 1221 form an acute angle with the first direction, in this case, the first contact surface 1211 can generate a horizontal component force along the first direction and a pressing force perpendicular to the upper surface of the conductive slider 220, and the second contact surface 1221 can generate a horizontal component force along the first direction and a pressing force perpendicular to the lower surface of the conductive slider 220. Thus, the conductive slider 220 may be facilitated to move in the first direction in the channel and the clamping action on both sides is maintained to facilitate maintaining good power transfer.
Correspondingly, the two opposite sides of the conductive slider 220 may also be inclined planes forming an angle with the horizontal plane, so as to make good contact with the first contact surface 1211 and the second contact surface 1221.
As shown in fig. 1 or fig. 2, in some embodiments, the power receiving apparatus 100 may further include a conductive base 130 and a first conductive connector 140, wherein the conductive base 130 is a base mounting member, and the first conductive connector 140 is used for connecting an external power source so as to transmit electric energy to the power receiving apparatus 100.
In order to mount the plurality of conductive modules 120, the conductive base 130 may be provided with a plurality of conductive brackets 110 along a first direction, and the plurality of conductive modules 120 are mechanically connected to the plurality of conductive brackets 110 in a one-to-one correspondence manner, so that the plurality of conductive modules 120 may be mounted and supported by the plurality of conductive brackets 110, respectively.
In order to realize the electrical conduction, the plurality of conductive brackets 110 are electrically connected to the conductive base 130, the plurality of conductive modules 120 are electrically connected to the plurality of conductive brackets 110 in a one-to-one correspondence, and the first conductive connecting element 140 is electrically connected to the conductive base 130. Based on this, the first conductive connecting element 140, the conductive base 130, the conductive brackets 110 and the conductive modules 120 can be electrically connected, and the conductive modules 120 are electrically connected with the conductive sliding block 220 capable of moving in the channel, and finally the conductive sliding block 220 transmits the electric energy to the workpiece to be electroplated through the electroplating fixture 200, so as to supply power.
Further, in some embodiments, the conductive base 130 may include a base body 131 and a second conductive connecting element 132, wherein the base body 131 has a receiving groove 1311, the second conductive connecting element 132 is disposed in the receiving groove 1311, and the plurality of conductive brackets 110 and the first conductive connecting element 140 are electrically connected, specifically, in an ohmic connection, to the second conductive connecting element 132.
