Description

Technical Field

[0001] The utility model relates to the field of solar cell and semiconductor manufacturing, and in particular to a conductive conveying device and electroplating equipment. Background Art

[0002] In the cell production process, the cells in some processes need to be powered on. For example, when the solar cell is electroplated, the cell is electrically connected to the negative electrode of the power supply to form a cathode. The anode is installed in the electroplating tank, and the anode is electrically connected to the positive electrode of the power supply. Under the action of the electric field, the metal ions in the electroplating solution will be liberated to the vicinity of the cell and form a coating on the cell. However, in the prior art, a conductive wire is usually used to connect the moving cell and the negative electrode of the power supply. Since the conductive wire needs to move with the cell, the connection of the conductive wire will be unstable and the conductivity between the cell and the power supply will be poor, thereby affecting the processing effect of the cell. In addition, the conductive wire needs to be connected manually, resulting in reduced efficiency of electroplating.

[0033] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] The utility model provides an electroplating device, which includes an electroplating tank (not shown in the figure) for containing electroplating solution, a battery cell loading and unloading device (not shown in the figure), a conductive connecting device (not shown in the figure), and a conductive conveying device. The electroplating device also includes an anode portion located in the electroplating tank, and the anode portion is electrically connected to the positive electrode of a power source. In the electroplating working state, the conductive conveying device clamps the battery cell 20 and conveys a negative current thereto, and the area to be plated of the battery cell 20 is immersed in the electroplating solution, thereby achieving electroplating of the area to be plated of the battery cell 20.

[0035] The conductive conveying device includes a clamping mechanism 10, a conductive mechanism, a conversion mechanism and a transmission mechanism, wherein the clamping mechanism 10 is used to clamp the battery cell 20, the transmission mechanism is used to transmit the clamping mechanism 10, the conversion mechanism is used to switch the opening and closing states of the clamping mechanism 10, and the conductive mechanism is used to transmit current to the battery cell 20.

[0036] The conductive mechanism includes a first conductive member 8 and a second conductive member 4. The first conductive member 8 is disposed on the clamping mechanism 10 and is electrically connected to the clamping mechanism 10. The second conductive member 4 is disposed on the transmission mechanism and is electrically connected to the negative pole of the power supply through a power line. In the working state, the first conductive member 8 and the second conductive member 4 are in sliding contact and electrically connected. In the process of the transmission mechanism transmitting the clamping mechanism 10, the conversion mechanism opens and closes the clamping mechanism 10, so that the clamping mechanism 10 can clamp the battery cell 20, and through the cooperation of the first conductive member 8 and the second conductive member 4, the current flows to the first conductive member 8, the clamping mechanism 10 and the battery cell 20 in sequence through the second conductive member 4, so as to realize the automatic loading and unloading and conduction of the battery cell 20.

[0037] The conductive transport device further includes a cell connector 30, which is conductive. Fig.10 As shown, the cell connector 30 has a first end 301 and a second end 302. The first end 301 can be fixed to the surface of the cell 20 by gluing so as to be electrically connected to the area to be plated of the cell 20 and move with the cell 20. The second end 302 is clamped by the clamping mechanism 10, and the second end 302 is electrically connected to the clamping mechanism 10 when being clamped, so as to be connected to the negative pole of the power supply. In this way, it can be avoided that the clamping mechanism 10 directly clamps the cell 20, resulting in damage to the cell 20.

[0038] See also Figures 1 to 9As shown, the transmission mechanism includes a frame 1, a transmission member (not shown in the figure) movably arranged on the frame 1, a clamping mechanism 10 is connected to the transmission member and can move with the transmission member, and the transmission path of the transmission member includes a first path and a second path with opposite transmission directions; the conversion mechanism and the second conductive member 4 are both arranged on the frame 1 and are both located on the first path. There are two conversion mechanisms, and the two conversion mechanisms are respectively located at two ends of the first path, and the second conductive member 4 is located between the two conversion mechanisms. In practical applications, the first path and the second path are respectively the working path and the return path. When the clamping mechanism 10 is located on the first path, it is opened by the conversion mechanism, and then closed, so as to clamp the battery cell 20, and then the second conductive member 4 and the first conductive member 8 cooperate to realize the current transmission of the battery cell 20. After the processing is completed, the clamping mechanism 10 contacts the conversion mechanism again. When the clamping mechanism 10 is in the open state again, the battery cell 20 is separated from the clamping mechanism 10, that is, when the clamping mechanism 10 enters the second path, the battery cell 20 is not clamped thereon, so as to realize the return of the clamping mechanism 10. When the clamping mechanism 10 enters the first path again through the second path, the above-mentioned action will be repeated. In this way, the clamping mechanism 10 can be reused to improve the electroplating efficiency.

[0039] The transmission mechanism also includes two drive wheels 2 arranged at intervals along the horizontal direction, and the two drive wheels 2 are each rotatably arranged on the frame 1 around the first center line X1. The transmission member moves along the transmission direction under the drive of the drive wheels 2 after passing through the above two drive wheels 2, and the second conductive member 4 is located between the two drive wheels 2 on the frame 1. In this embodiment, the transmission direction of the transmission member is a closed loop, and the first path and the second path are respectively two horizontal sections of the closed loop. The transmission mechanism also includes two upper drive wheels 3 arranged at intervals along the horizontal direction, and the two upper drive wheels 3 are each rotatably arranged on the frame 1 around the second center line X2, and the second center line X2 is parallel to the first center line X1 and is located above the first center line X1. The transmission member is also a closed loop. The transmission member passes through the two drive wheels 2 in the transmission direction and then passes through the two upper drive wheels 3 in turn to form a transmission closed loop. The transmission closed loop is a quadrilateral, and the first path and the second path are respectively two parallel sides of the quadrilateral. Preferably, the transmission closed loop is surrounded to form an isosceles trapezoidal area.

[0040] Specifically, referring to the drawings, in this embodiment, the frame 1 has a horizontal guide section 11 for providing a transmission member with a transmission movement guide in the horizontal direction, and the second conductive member 4 is fixedly arranged on the horizontal guide section 11 and extends in the horizontal direction. The second conductive member 4 has one or a plurality of second conductive members 4 arranged at intervals in the horizontal direction. The number and position of the second conductive members 4 mainly correspond to the number and position of the electroplating tanks in the electroplating equipment. When the negative pole of the power supply needs to be connected, that is, when the battery cell is transmitted through the electroplating tank and needs to be electroplated, the corresponding position above the corresponding electroplating tank should be provided with a second conductive member 4, so that the second conductive member 4 and the first conductive member 8 cooperate with each other and maintain electrical connection. In this embodiment, the first conductive member 8 is a conductive block fixedly arranged on the connecting frame 6, and the second conductive member 4 is a conductive plate extending in the horizontal direction. In the electroplating working state, the conductive block slides against the surface of the conductive plate, so that the two can maintain electrical connection in a state of relative movement.

[0041] In this embodiment, see Figure 1 , Figure 2 As shown, the frame 1 also includes a return guide section 12 located above the horizontal guide section 11 and parallel to it, and two connecting guide sections 13 connected between the ends of the horizontal guide section 11 and the return guide section 12. A base 14 is also fixedly arranged between the ends of the horizontal guide section 11 and the return guide section 12, and a group of driving wheels 2 and upper driving wheels 3 are correspondingly arranged on each base 14, and one of the driving wheels 2 is also connected to a driving assembly including a motor 5, and when the motor 5 is working, it drives the driving wheel 2 to rotate around the first center line X1, so that the transmission member moves along the transmission direction. As a preferred mode, the above-mentioned transmission member is a chain, and the driving wheel 2 and the upper driving wheel 3 are both sprockets.

[0042] During the electroplating process, the second conductive member 4 is connected to the negative pole of the power source through the power line and is fixed to the frame 1; the clamping mechanism 10 clamps the second end 302 of the cell connector 30, and the first conductive member 4 on the clamping mechanism 10 and the second conductive member 8 are in sliding contact and electrically connected. Since the first conductive member 4 is electrically connected to the clamping mechanism 10, the area to be electroplated on the cell 20 can be connected to the negative pole of the power source. In this way, it is only necessary to ensure the electrical connection between the first conductive member 4 and the second conductive member 8, so that the cell 20 can be stably connected to the power source during the horizontal electroplating process, avoiding the problem of affecting the processing effect due to poor conductivity.

[0043] The clamping mechanism 10 includes a connecting frame 6 and a clamping assembly 7. The first conductive member 4 and the clamping assembly 7 are respectively arranged at the upper and lower parts of the connecting frame 6. The connecting frame 6 is connected to the transmission member. The second conductive member 8 is arranged on the upper surface of the frame 1. The clamping assembly 10 includes two clamping members 71 and a linkage assembly for driving the two clamping members 71 to move closer or farther. The top of the conversion mechanism is connected to the lower surface of the frame 1. There is a height difference between the lower surface of the conversion mechanism and the lower surface of the frame 1. In the working state, the first conductive member 4 is located on the upper surface of the frame 1, and is in contact with the second conductive member 8 and electrically connected. The linkage assembly moves along the lower surface of the frame 1, and when it contacts the conversion mechanism, the two clamping members 71 move away from each other. In this way, by separating the conductive part and the clamping part of the clamping mechanism 10, the two actions of obtaining current and clamping the battery cell 20 can be performed simultaneously. The conductive conveying device has at least two working states. In the first working state, the linkage component contacts the conversion mechanism and drives the two clamping members away from each other. In the second working state, the linkage component contacts the surface of the frame and drives the two clamping members closer to each other, and the first conductive member and the second conductive member are in contact and electrically connected. Furthermore, the conductive conveying device also has a third working state. In the third working state, the linkage component contacts the surface of the frame and drives the two clamping members closer to each other, and the first conductive member and the second conductive member are not in contact. When the conductive conveying device is in the first working state and in the second working state, the transmission direction of the clamping mechanism is the same, and when the conductive conveying device is in the second working state and in the third working state, the transmission direction of the clamping mechanism is opposite.

[0044] The clamping mechanism 10 includes a connecting frame 6, which includes a mounting rod 61 and a connecting seat 62. The connecting seat 62 and the clamping assembly 7 are both connected to the mounting rod 61 and are respectively arranged above and below the mounting rod 61. The connecting seat 62 is connected to the transmission member; the second conductive member 4 is arranged on the upper surface of the frame 1, and the first conductive member 8 is arranged on the connecting seat 62. In the working state, the first conductive member 8 is located on the upper surface of the frame 1, and is in sliding contact with the second conductive member 4 and electrically connected.

[0045] The clamping assembly 7 also includes a mounting seat 72, which is arranged on the lower surface of the mounting rod 61. The linkage assembly includes a rolling member 74, a first connecting rod 73, two second connecting rods and two third connecting rods. The rolling member 74 is arranged at one end of the first connecting rod and passes through the mounting rod 61. The other end of the first connecting rod 73 passes through the mounting seat 72 and is hinged to the two second connecting rods. One end of the two third connecting rods is respectively hinged to the two second connecting rods, and the other end is hinged to the mounting seat 72. The two clamping members 71 are respectively connected to the two second connecting rods, and the connection is located between the two hinge points of the second connecting rods.

[0046] Furthermore, a retaining structure is provided on the first connecting rod 73 , and the retaining structure is located between the mounting seat 72 and the mounting rod 61 , so that the first connecting rod 73 performs vertical reciprocating motion in the mounting seat 72 .

[0047] The conversion mechanism provided on the frame 1 is specifically a lifting protrusion 15, as shown in FIG. Figure 2 , Fig.10 As shown, the lifting protrusion 15 has a plane 15a and two inclined surfaces 15b on both sides of the plane 15a. Along the transmission direction, the inclined surface 15b gradually extends from the lower surface of the frame 1 toward the plane 15a. When the clamping mechanism 10 moves along the transmission direction, before reaching the position of the conversion mechanism, the rolling element 74 rolls against the frame 1 and does not contact the lifting protrusion 15; when the clamping mechanism 10 reaches the position of the conversion mechanism, the rolling element 74 first moves along the inclined surface 15b on one side and gradually reaches the plane 15a. In this process, the first link The rod 73 is pushed to move toward the clamping member 71, so that the two second connecting rods are subjected to a thrust, driving the two clamping members 71 to move away from each other, so that the clamping assembly 7 is transformed from a closed state to an open state, and at this stage, the second end 302 is clamped or the clamping of the second end 302 is released; then the rolling member 74 moves along the inclined surface 15b on the other side and gradually disengages from the lifting protrusion 15. During this process, the thrust received by the second connecting rod disappears, driving the two clamping members 71 to move toward each other, so that the clamping assembly 7 is transformed from an open state to a closed state.

[0048] Specifically, see Figures 5 to 9 As shown, the mounting seat 72 is fixed on the mounting rod 61. In this embodiment, the retaining structure is a spring 75. A positioning nut is provided on the first connecting rod 73. The two ends of the spring 75 are respectively against the positioning nut and the mounting seat 72. The spring 75 is used to provide the elastic force required for the first connecting rod 73 to move away from the clamping member 71, and can keep the clamping assembly 7 in a closed state when no external force is applied. Figures 3 to 9 As shown, in the clamping mechanism 10, the clamping member 71 has a clamping portion, and the clamping portions of the two clamping members 71 are located in corresponding positions, the first conductive member 8 is electrically connected to at least one clamping portion, and the clamping assembly 7 has an open state and a closed state. When the clamping assembly is in the open state, the clamping portions of the two clamping members 71 are separated and have a certain distance, so that the second end 302 of the cell connector 30 can enter between the two clamping portions; when the clamping assembly 7 is in the closed state, the two clamping portions abut against each other, so that the second end 302 can be clamped between the two clamping portions and contact with the conductive clamping portion to form an electrical connection. In the electroplating working state, the above-mentioned clamping assembly 7 is in a closed state, that is, the clamping assembly 7 forms a clamp on the second end 302 and an electrical connection with the second end 302.

[0049] In this embodiment, each clamping member 71 includes two clamping parts that are spaced apart, namely a first clamping part 71a and a second clamping part 71b. The two first clamping parts 71a of the two clamping members 71 are positioned correspondingly, and the two second clamping parts 71b are positioned correspondingly. When the clamping assembly 7 is in a closed state, the two first clamping parts 71a cooperate with each other to abut against each other, and the two second clamping parts 71b cooperate with each other to abut against each other, wherein one or both of the two first clamping parts 71a are in a conductive state, and one or both of the two second clamping parts 71b are in a conductive state. Specifically, any one of the clamping parts is electrically connected to the first conductive member 8, and the remaining clamping parts in a conductive state are electrically connected to each other.

[0050] In this way, when electroplating is performed on both the front and back sides of the battery cell 20, the two first clamping portions 71a can cooperate with each other to clamp the second end 302 of the battery cell connector 30 connected to the area to be electroplated on the front side of the battery cell 20, and the two second clamping portions 71b can cooperate with each other to clamp the second end 302 of the battery cell connector 30 connected to the area to be electroplated on the back side of the battery cell 20. In this way, the same clamping assembly 7 can simultaneously clamp the two battery cell connectors 30 connecting the front and back sides of the same battery cell 20. Fig.10 As shown, the problem of debris or affecting the processing quality caused by asynchronous transmission caused by clamping of different clamping assemblies 7 is avoided.

[0051] In this embodiment, a clamping assembly 7 and a connecting seat 62 together constitute a conductive conveying assembly, and a conductive conveying assembly is respectively arranged at both ends of the mounting rod 61. Specifically, the clamping mechanism 10 includes two groups of clamping assemblies 7, and the two groups of clamping assemblies 7 are arranged at intervals along the first direction, and the first direction is perpendicular to the transmission direction, which is specifically a direction parallel to the first center line X1 and the second center line X2. A first conductive member 8 is arranged on each connecting seat 62, that is, there are two first conductive members 8, and they are arranged at intervals along the first direction, and the two first conductive members 8 are each electrically connected to the corresponding conductive clamping part in the clamping assembly 7 through a wire 9. In the electroplating working state, the two first conductive members 8 are simultaneously in contact with the second conductive member 4 in a sliding manner to maintain electrical connection. In the process of the clamping mechanism 10 moving along the transmission direction, the two groups of clamping assemblies 7 can be connected to the two groups of battery cells 20 arranged at intervals along the first direction, which is convenient for realizing dual-line simultaneous electroplating production and improving production capacity. Correspondingly, two sets of conversion mechanisms are arranged side by side on the frame 1, and the two sets of conversion mechanisms are spaced apart along the first direction to respectively convert the open state and the closed state of the two sets of clamping assemblies 7 on the same clamping mechanism 10. Of course, the two clamping assemblies 7 can also be electrically connected to the two sides of a battery cell, that is, one clamping assembly 7 clamps two battery cell connectors 30, and the two battery cell connectors 30 belonging to the same clamping assembly 7 are electrically connected to the same side of the battery cell to improve the stability of current input.

[0052] A guide member 63 is provided on each connection seat 62, and the two connection seats 62 are respectively fixedly connected to the transmission member, and the two guide members 63 are respectively connected to the frame 1 in a sliding manner, wherein the two first conductive members 8 are located between the two connection seats 62.
