Description

Technical Field

[0001] The utility model relates to the technical field of battery sheet production equipment, in particular to an anti-adhesion fixture for loading battery sheets. Background Technique

[0002] "Phosphorus diffusion" is a process step in the manufacture of solar cell sheets. It involves diffusing phosphorus elements into the surface of silicon wafers to improve the performance of the cells. When performing the phosphorus diffusion process, a manipulator is needed to grab the battery sheets and place them into a quartz boat for diffusion. Traditional manipulators usually use suction cups to grab the battery sheets, and side clamps are arranged on both sides of the suction cups for auxiliary clamping. When placing the battery sheets, after the suction cups break the vacuum, the battery sheets adsorbed by the suction cups on the manipulator fall off by their own gravity and fall into the quartz boat. However, in actual use of this kind of manipulator, the adsorption between the suction cup and the battery sheet may be too tight, resulting in the difficulty of the battery sheet falling off naturally, affecting the subsequent diffusion process and increasing the fragmentation rate of the battery sheet.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] When a traditional manipulator places a battery cell, the adsorption between the suction cup and the battery cell may be too tight, resulting in the battery cell being difficult to fall off naturally and affecting the subsequent diffusion process.

[0023] To solve the defects existing in the above-mentioned manipulator during the process of placing the battery cell, please refer to Figures 1-5, a non-sticking fixture for loading battery wafers provided by the utility model can assist the battery wafer to detach from the suction cup 3 through the material discharging mechanism 6, ensuring that the battery wafer smoothly falls into the quartz boat. The grasping mechanism is based on the grasping plate 1. A connecting pipe 2 is slidably installed inside the grasping plate 1. The connecting pipe 2 is arranged at the center of the grasping plate 1. A suction cup 3 is arranged at the lower end of the connecting pipe 2. The suction cup 3 is used to suck the battery wafer. On both sides of the bottom of the grasping plate 1, side clamps 4 for clamping the battery wafer are slidably connected. On the one hand, the side clamps 4 are used to assist the suction cup 3 to fixedly grasp the battery wafer, enhancing the stability of the battery wafer during transportation. On the other hand, they can ensure the limitation of both sides of the battery wafer, ensuring that the battery wafer can enter the quartz boat neatly. And suspension rods 5 are fixedly connected to the four corners of the grasping plate 1. A material discharging mechanism 6 for pressing the battery wafer downward as the two side clamps 4 move away from each other is arranged on the suspension rods 5. When placing the battery wafer, while the suction cup 3 breaks the vacuum, control the two side clamps 4 to move away from each other to release the battery wafer. During the process of the side clamps 4 releasing, the material discharging mechanism 6 is driven to press the battery wafer downward. Even if a battery wafer cannot fall off due to being adsorbed too tightly by the suction cup 3, the battery wafer can be detached from the suction cup 3 through the material discharging mechanism 6, ensuring that the battery wafer smoothly falls into the quartz boat and facilitating the smooth progress of the subsequent diffusion process.

[0024] In order to achieve the effect that the material discharging mechanism 6 presses the battery wafer downward as the side clamps 4 release to promote the separation of the battery wafer from the suction cup 3, guide rails 7 are rotatably installed at the front and rear ends of the side clamps 4. The material discharging mechanism 6 is installed on the guide rails 7. The suspension rod 5 and the side clamp 4 on the same side are arranged side by side. One end of the guide rail 7 close to the suction cup 3 is inclined downward, and the downward inclined end of the guide rail 7 is not lower than the bottom of the side clamp 4, providing a grasping space for the battery wafer. Among them, a guide rod 66 is movably installed in the guide rail 7. The guide rod 66 is adapted to the guide rail 7. The front end of the guide rod 66 is fixedly connected with a lifting block 61. A pressing plate 62 is arranged at the end of the lifting block 61. A plurality of longitudinally uniformly distributed slots 63 are formed inside the lifting block 61. A limiting member 64 is arranged on the top of the pressing plate 62. The pressing plate 62 is inserted into any one of the slots 63 through the limiting member 64. And an arc-shaped pressing block 65 is arranged at the lower end of the pressing plate 62. Refer to Figure 1 and Figure 2 As shown, when the two side clamps 4 move away from each other to release the battery wafer, they can drive the guide rail 7 to move synchronously. The movement of the guide rail 7 pulls the lifting block 61 through the guide rod 66, causing the lifting block 61 to slide down along the guide rail 7. The lifting block 61 drives the pressing plate 62 to slide down. The pressing plate 62 can press the battery wafer downward through the arc-shaped pressing block 65, realizing the separation of the battery wafer from the suction cup 3.

[0025] In actual production, the thickness of the battery wafers may vary. If the height of the pressing plate 62 is set fixedly, when the device grabs a thicker battery wafer, the battery wafer may conflict with the arc-shaped pressing block 65, affecting the grabbing operation. When grabbing a thinner battery wafer, the downward extrusion range of the arc-shaped pressing block 65 is limited, and the extrusion force may not be applied to the battery wafer, resulting in the possibility that the battery wafer still cannot fall off. To solve this technical problem, the limiting member 64 needs to be set as an integrally formed elastic pressing piece 641. The elastic pressing piece 641 is fixedly installed at the upper end of the pressing plate 62. Convex strips 642 are provided at both the top and bottom of the elastic pressing piece 641. Limiting grooves 67 adapted to the convex strips 642 are provided on the inner walls of multiple slots 63. During use, according to the thickness of the battery wafer, the elastic pressing piece 641 can be inserted into the slot 63 at the corresponding height, so that when the side clamp 4 is in the clamping state, the height difference between the bottom of the arc-shaped pressing block 65 and the bottom of the side clamp 4 is equal to or slightly greater than the thickness of the battery wafer. By inserting the elastic pressing piece 641 into different slots 63, the device can grab battery wafers of different thicknesses. When the elastic pressing piece 641 is inserted into the slot 63, the elastic pressing piece 641 can press the convex strip 642 into the limiting groove 67 through its own elastic force, and the elastic pressing piece 641 can be fixed in the slot 63, thereby realizing the adjustment of the height of the arc-shaped pressing block 65.

[0026] To further increase the adjustability of the process of the arc-shaped pressing block 65 pressing the battery wafer downward, a rotating shaft 9 is fixedly connected between the two side guide rails 7 on the same side. A groove 11 for the rotating shaft 9 to rotate is provided on the side surface of the side clamp 4. A first bevel gear 10 is fixedly sleeved on the outer surface of the rotating shaft 9. A second bevel gear 12 meshing with the first bevel gear 10 is rotatably installed on the inner wall of the groove 11. The center of the second bevel gear 12 is fixedly connected with a handle 13. The handle 13 needs to be manually applied with an external force to rotate. Rotating the handle 13 can drive the rotating shaft 9 to rotate through the second bevel gear 12 and the first bevel gear 10. The rotation of the rotating shaft 9 can adjust the inclination angle of the guide rail 7, and further adjust the downward extrusion distance of the arc-shaped pressing block 65, facilitating the staff to adjust it according to the actual situation.

[0027] To realize the clamping and releasing actions of the side clips 4 on the solar wafers, a slider 15 is fixedly connected to the top of the side clip 4. A sliding groove 16 for the slider 15 to slide is formed on the gripping plate 1. A rotating ring 14 is rotatably installed at the center position of the top of the gripping plate 1. Connecting rods 17 are arranged between the rotating ring 14 and the two sliders 15. The two ends of the connecting rod 17 are respectively rotatably installed on the rotating ring 14 and the slider 15. An idle gear 20 is fixedly connected to the inner wall of the rotating ring 14. A servo motor 18 is fixedly installed on one side of the top of the gripping plate 1. The output end of the servo motor 18 is fixedly connected with a driving gear 19 that meshes with the idle gear 20. Driving the servo motor 18 can drive the rotating ring 14 to rotate through the driving gear 19 and the idle gear 20. The rotation of the rotating ring 14 drives the two sliders 15 to slide synchronously in opposite directions through the connecting rods 17. The sliders 15 can drive the two side clips 4 to clamp or release the solar wafers.

[0028] Referring to Figure 1 As shown, an air pipe 21 communicating with the suction cup 3 is installed on the back of the connecting pipe 2. The air pipe 21 is connected to an external starting system to realize the sucking and putting down of the solar wafers by the suction cup 3. An installation base 8 is installed at the upper end of the connecting pipe 2. The whole device can be installed on the robotic arm through the installation base 8, and the transfer of the solar wafers is realized through the robotic arm.

[0029] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model mainly aims to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.

[0030] It should be noted that in this article, the term "comprising", "including" or any other variation thereof is intended to cover a non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
