Description

Technical Field

[0001] The present invention relates to the technical field of inter-process transportation of battery cells, and in particular to an inter-process transportation method of battery cells. Background Art

[0002] As an important component of solar cells, silicon wafers currently require inserting machines in the production of photovoltaic cell silicon wafers. The inserting machine is used to insert the cell silicon wafers into the material basket one by one for better storage and processing of the cell silicon wafers. In the entire process of silicon cell manufacturing, the surface cleanliness of silicon wafers during transportation plays a vital role. If the surface of the silicon wafer is contaminated with impurities during the storage stage, the residual impurities will easily diffuse into the interior of the silicon wafer in the subsequent high-temperature process environment, causing defects and producing a large number of silicon wafers that need to be reworked. Even if some defective silicon wafers have their surface defects removed through subsequent wet treatment, their internal defects may still lead to abnormal electroluminescent characteristics and electrical properties.

[0003] The existing Chinese patent with publication number CN116995010B includes: a conveying mechanism installed on a base frame for conveying battery silicon wafers; a material basket for inserting battery silicon wafers; a lifting mechanism for driving the material basket to lift one by one; a deceleration mechanism arranged in the material basket for decelerating the battery silicon wafers; the conveying mechanism conveys the battery silicon wafers into the insertion material basket, and during the process of inserting the battery silicon wafers into the material basket, the deceleration mechanism decelerates the battery silicon wafers so that the speed of the battery silicon wafers stops when the battery silicon wafers are just completely inserted into the material basket.

[0004] When the above device is in use, a deceleration mechanism is provided inside the basket, and the battery silicon wafer contacts the deceleration mechanism during the insertion process. The deceleration mechanism decelerates the battery silicon wafer, so that the speed stops when the battery silicon wafer is just fully inserted into the slot, avoiding the collision between the battery silicon wafer and the inner wall of the slot, and achieving the purpose of protecting the battery silicon wafer. However, in actual use, since the battery silicon wafer is horizontally inserted during the insertion process, and the battery silicon wafer inside the basket is in a horizontal state, the gravity and contamination contact area of ​​the battery silicon wafer inside the basket during the transportation process are large, which easily causes particulate foreign matter to contaminate the surface of the battery silicon wafer. Affecting the qualified rate of the finished battery silicon wafer, it is difficult to adjust the battery silicon wafer inside the basket to a vertical transportation posture during the transportation process.

[0005] To this end, we proposed a method for transferring battery cells between processes. Summary of the invention

[0006] The object of the present invention is to provide a method for transferring battery cells between process steps, which has the advantage of adjusting the battery silicon wafers inside the basket to a vertical transportation posture, thereby solving the problems in the background technology.

[0007] To achieve the above object, the present invention provides the following technical solution: a method for transferring a battery cell between processes, comprising the following steps: S1. Clamping the basket: After the battery silicon wafers are inserted into the basket through the process, the threaded rod drives the movable sleeve to move horizontally toward the end close to the first L-shaped plate, so that the limit rod pulls the gear and the spline shaft to move horizontally toward the direction close to the inclined plate under the action of the movable block and the first guide groove, so that the inclined plate can drive the clamping plates at both ends to move toward each other under the action of the trapezoidal block, so that the clamping plates clamp and fix the basket; S2, transfer basket: after the clamping plate clamps the basket, the threaded rod drives the movable sleeve to reset and move toward the end away from the first L-shaped plate, and then the rectangular frame can transfer the basket to the corresponding position of the conveying mechanism under the action of the movable sleeve; S3, flipping the basket: when the movable sleeve drives the basket to be transferred toward the end away from the first L-shaped plate, the gear can drive the spline shaft to rotate 90 degrees under the action of the tooth plate, so that the spline sleeve rod can drive the rectangular frame to rotate 90 degrees synchronously under the action of the spline shaft, and the rectangular frame rotates to a horizontal state, and then the clamping plate changes the battery silicon wafers in the basket from horizontal transportation to vertical transportation posture; S4, material unloading operation: when the rectangular frame drives the material basket to the limit distance at one end of the conveying mechanism, the movable block can drive the limit rod to move horizontally towards the direction close to the rectangular frame under the action of the second guide groove, and the inclined plate can drive the clamping plates at both ends to move in opposite directions under the action of the trapezoidal block, so that the clamping state of the material basket is released, and the material basket can fall to the surface of the conveying mechanism under its own gravity, and then the conveying mechanism transports the material basket to the next process.

[0008] Preferably, it includes a base fixedly placed on the ground, one side of the base is fixedly connected to a track plate through an external bracket, and the end of the base close to the track plate is fixedly connected to a lifting mechanism for lifting and lowering, the top of the lifting mechanism is fixedly connected to a placement plate, a material basket for storing silicon wafers is placed on the placement plate, a conveying mechanism for conveying the plugged material basket to the next process is fixedly connected at a symmetrical position on the track plate away from one end of the placement plate, and the track plate is provided with a transport mechanism for transporting the material basket and a flipping mechanism for flipping and adjusting the posture of the material basket.

[0009] Preferably, the transfer mechanism includes an inner wall of a track plate movably connected to a movable sleeve for horizontal reciprocating movement, and both ends of the track plate are penetrated and fixedly rotatably connected with a threaded rod driven by a power mechanism, and the threaded rod penetrates the inner wall of the movable sleeve and is screwed, and the movable sleeve is provided with a clamping mechanism for clamping the material basket.

[0010] Preferably, the clamping mechanism includes a rectangular block fixedly connected to a movable sleeve, a spline sleeve rod penetrating through the rectangular block and rotatably connected, a rectangular frame fixedly connected to the outer contour of the spline sleeve rod close to one end of the placement plate, inclined panels movably connected to the two ends of the rectangular frame at symmetrical positions on the side away from the spline sleeve rod, and limiting grooves for supporting the inclined panels are provided on the opposite surfaces of the rectangular frame at the side away from the spline sleeve rod, clamping plates for clamping the material basket are fixedly connected to the symmetrical positions of the two inclined panels, and the spline sleeve rod is provided with an auxiliary mechanism for driving the two clamping plates to move toward each other to clamp the material basket.

[0011] Preferably, the auxiliary mechanism includes a spline sleeve whose inner wall is penetrated and axially movably connected with a spline shaft, and the end of the spline shaft close to the clamping plate is fixedly connected to a trapezoidal block that pulls the inclined plate to move toward or away from each other, and support grooves for supporting the trapezoidal blocks are provided on the inclined surfaces on the adjacent sides of the two inclined plates, and the two sides of the trapezoidal blocks are respectively penetrated to the inner walls of the support grooves on the adjacent sides and movably connected, and the end of the spline shaft away from the trapezoidal block is coaxially fixed with a gear.

[0012] Preferably, the rectangular block is penetrated by a limit rod and connected for horizontal movement, and the end of the limit rod away from the rectangular frame is sleeved on the outer contour of the gear and movably connected, a movable groove connected to the limit rod is opened on the top side of the rectangular block, a movable block for pulling the limit rod for horizontal movement is fixedly connected to the limit rod, and the movable block penetrates to the inner wall of the movable groove and is movably connected, a first L-shaped plate is fixedly connected to one end of the track plate close to the movable sleeve, a first guide groove is opened on the first L-shaped plate for pulling the clamping plate to move toward each other to clamp the material basket, and a rectangular through groove is opened on the placement plate for the clamping plate to move to clamp the material basket.

[0013] Preferably, the flipping mechanism includes a tooth plate fixedly connected to a side of the track plate away from the conveying mechanism, and the tooth plate is adapted to the teeth on the gear.

[0014] Preferably, the end of the track plate away from the first L-shaped plate is fixedly connected to a second L-shaped plate, and the second L-shaped plate is provided with a second guide groove for pulling the clamping plate to move backward to unload the material basket, and the position of the second guide groove is opposite to the first guide groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Accurately clamp and fix the battery cells before the basket is transported. By controlling the clamping and transporting actions of the splint on the basket, accurate transportation of the battery silicon wafers can be achieved, effectively avoiding possible material damage or deviation during the transport process, and ensuring high-precision requirements in the production process.

[0016] 2. During the transportation process, the basket can be flipped 90 degrees through the coordinated use of gears and toothed plates, and then the splint can transform the battery silicon wafers inside the basket from horizontal handling to vertical handling. By using gravity and the principle of reducing the pollution contact area, the contact between particulate pollutants and the surface of the silicon wafers can be effectively isolated, greatly reducing the adverse effects of surface contamination. At the same time, vertical handling of battery silicon wafers can effectively alleviate the problem of silicon wafer deformation caused by thinning faced by the current industry, significantly improve the qualified rate of finished products, and have a positive effect on the comprehensive electrical properties of silicon wafers.

[0017] 3. When the rectangular frame drives the material basket to the maximum distance at one end of the conveying mechanism, the movable block can drive the limit rod to move horizontally toward the direction close to the rectangular frame under the action of the second guide groove, so that the material basket can be released from the clamping state, and the material basket falls to the surface of the conveying mechanism under its own gravity, and then the conveying mechanism transports the material basket to the next process.

[0018] The above structure is used in conjunction to solve the problem that in the actual use of the existing device, since the battery silicon wafers are plugged in horizontally during the plugging process and the battery silicon wafers inside the basket are in a horizontal state, the gravity and contamination contact area of ​​the battery silicon wafers inside the basket during the transportation process are large, which easily causes particle foreign matter to contaminate the surface of the battery silicon wafers. This affects the qualified rate of the finished battery silicon wafers, and therefore it is difficult to adjust the battery silicon wafers inside the basket to a vertical transportation posture during the transportation process.
