Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic equipment manufacturing, and in particular relates to a transmission roller structure suitable for battery slices of various sizes. Background Art

[0002] Solar photovoltaic cells are key components in photovoltaic power generation. Traditional metal mesh belt sintering furnaces were previously used for production. However, these systems suffered from high energy consumption and pollution, failing to meet China's green energy development requirements. Currently, low-energy sintering furnaces based on ceramic rollers have replaced these traditional metal mesh belt sintering furnaces. While metal mesh belts remove significant heat during sintering, consuming significant energy, ceramic rollers remove virtually no heat, significantly reducing the energy required for cell production and making them ideal for transporting cells. However, the high cost and difficulty of processing ceramic rollers have resulted in low production yields. Using ceramic rollers exclusively throughout the sintering line would increase equipment costs. Considering the trade-off between equipment cost and energy consumption, a more economical solution is to use all-ceramic rollers for high-temperature areas exceeding 350°C, while using metal rollers for temperatures below 350°C. Metal rollers offer advantages over ceramic rollers in terms of cost, precision, and ease of processing. In order to achieve better supporting effect, ceramic rings are installed on the metal roller according to the size of the battery cell. The inclined surfaces on both sides of the battery cell are placed on the ceramic rings. The battery cell is transferred by rotating the metal roller and the ceramic ring at the same time, so that the back of the battery cell does not contact the metal roller, avoiding wear of the battery cell.

[0003] In the past, the size of battery cells in the industry was relatively stable. Therefore, when fixing the ceramic ring to the metal roller, it was only necessary to reserve some fixed holes on the metal roller in advance to meet the size adjustment requirements. However, in recent years, the size of battery cells in the industry has become more and more subdivided. The size difference between some battery cells may be only 2-5cm. For such a small size difference, if holes are still punched on the metal roller, the hole spacing will be too close, which will damage the strength of the metal roller. The weakened metal roller is easily deformed at high temperatures, resulting in poor transmission effect. Therefore, the existing fixing method needs to be improved. Utility Model Content

[0004] In response to the above problems and technical requirements, the present invention provides a roller structure suitable for transmitting battery cells of various sizes. This structure can maintain the strength of the metal roller while being compatible with the transmission requirements of battery cells of various sizes.

[0005] The technical solution of the utility model is as follows: a battery cell transmission roller structure suitable for various sizes, including a metal roller, a fixed plate, a ceramic ring assembly and a roller transmission mechanism, a plurality of metal rollers are connected between the relatively arranged fixed plates, the metal rollers are parallel and equidistantly spaced, the two ends of the metal roller are respectively rotatably connected to the two fixed plates, a roller transmission mechanism is provided on the outer side surface of a fixed plate, and the roller transmission mechanism can drive all the metal rollers to rotate synchronously; each metal roller is provided with two ceramic ring assemblies, the ceramic ring assemblies and the metal rollers are detachably connected, the ceramic ring assemblies can freely adjust the spacing and lock on the metal rollers, and all the metal rollers lock the ceramic ring assemblies at the same position.

[0006] Furthermore, the ceramic ring assembly includes a metal fixing ring, a ceramic ring and an overlapping fixing block. The ceramic ring is sleeved on the metal roller rod. The metal fixing ring is fixed on the metal roller rod close to the ceramic ring. The metal fixing ring and the metal roller rod are clamped together. The metal fixing ring and the ceramic ring are locked together by the overlapping fixing block.

[0007] Furthermore, the ceramic ring is an integrally formed part, comprising a cylindrical section and a conical section. The cylindrical section is in close contact with the metal fixing ring, and the conical section is arranged inside the cylindrical section. The conical surface of the conical section can support the battery cell workpiece.

[0008] Furthermore, a pin hole is provided on the circumferential surface of the cylindrical section of the ceramic ring, a screw hole adjacent to the pin hole is provided on the metal fixing ring, a fixing pin is provided at the bottom of the overlapping fixing block, and a countersunk hole is provided on the overlapping fixing block. The fixing pin is inserted into the pin hole accordingly, and the position of the countersunk hole corresponds to the screw hole. The countersunk hole and the screw hole are fixedly connected by screws.

[0009] Furthermore, the metal fixing ring is a split ring, which includes an upper half ring and a lower half ring. The two ends of the upper half ring and the lower half ring are opposite to each other to hold the metal roller rod tightly. The opposite ends of the upper half ring and the lower half ring are respectively a locking end face and an adjusting end face. The locking end faces are fixedly connected by bolts. A gap is provided between the adjusting end faces. The adjusting end faces are connected by adjusting bolts. The adjusting bolts can adjust the distance of the gap so that the upper half ring and the lower half ring can hold or loosen the metal roller rod.

[0010] Furthermore, a positioning column and a fastening screw hole are provided on the locking end face of the lower half ring, an adjusting screw hole is provided on the adjusting end face of the lower half ring, and bolt countersunk holes are respectively provided on both sides of the upper half ring. The lower end ports of the bolt countersunk holes are arranged on the locking end face and the adjusting end face of the upper half ring. A positioning hole corresponding to the positioning column is also provided on the locking end face of the upper half ring, and the bolt countersunk holes and the fastening screw holes and the adjusting screw holes on both sides are respectively connected by bolts.

[0011] In the above scheme, the upper half ring and the lower half ring clamped on the metal roller rod are equivalent to a clamp. When the adjusting bolt passes through the bolt countersunk hole and the adjusting screw hole and is tightened, the gap between the two adjustment end faces gradually shrinks, and the metal roller rod can be clamped and locked. Since the metal fixing ring is locked with the ceramic ring through the overlapping fixing block, the ceramic ring is fixed at this point. The metal fixing ring can be clamped and fixed at any position of the metal roller rod, so the spacing between the ceramic rings can also be adjusted arbitrarily without drilling holes in the metal roller rod, thereby retaining the integrity of the metal roller rod.

[0012] Furthermore, the top of the upper half ring is provided with a positioning groove, into which the countersunk section of the overlapping fixing block is correspondingly inserted. A screw hole is provided at the center of the positioning groove, and the countersunk section of the overlapping fixing block is fixedly connected to the screw hole. The positioning groove can limit the position of the overlapping fixing block, thereby enhancing the fixing effect between the overlapping fixing block and the upper half ring.

[0013] Furthermore, both ends of the metal roller extend out of the fixed plates at both sides, and the metal roller is rotatably connected to the fixed plates at both ends via bearings, and the fixed plates are provided with a plurality of bearing grooves for mounting bearings.

[0014] Furthermore, the roller transmission mechanism includes a transmission main shaft, a driving gear and a driven gear. The transmission main shaft is arranged on the outside of the fixed plate parallel to the transmission direction. A plurality of driving gears are fixed on the transmission main shaft. The driven gear is fixed at the end of the metal roller. The driving gear and the driven gear are meshed and connected one by one. The transmission main shaft drives the driven gear and the metal roller to rotate through the driving gear.

[0015] Furthermore, a coupling is provided at the end of the transmission main shaft, which transmits power to the transmission main shaft. The coupling is connected to an external motor to drive the transmission main shaft to run and feed the material.

[0016] The beneficial effects of the present invention are as follows: the present invention improves the ceramic ring assembly, and adopts a ceramic ring and a metal fixing ring in combination. Only one pin hole is required on the ceramic ring to achieve limit locking with the metal fixing ring, and no through hole is required on the ceramic ring. This can greatly reduce the difficulty of processing the ceramic ring and improve the yield rate during the processing of the ceramic ring; and no hole position needs to be reserved on the metal roller rod. The split metal fixing ring is equivalent to a clamp, which can be clamped and connected to the metal roller rod from the outside to achieve the purpose of fixing the ceramic ring to the metal roller rod. The metal fixing ring can be clamped and fixed at any position on the metal roller rod. The distance between the two ceramic rings can be continuously adjusted, which meets the transmission requirements of battery cell workpieces of different sizes, maintains the integrity of the metal roller rod, and prevents the metal roller rod from deforming at high temperatures, making the transmission of the battery cells more stable.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-7 The figure shows a roller structure for transmitting battery cells of various sizes suitable for the present invention, including a metal roller 1, a fixed plate 2, a ceramic ring assembly 3 and a roller transmission mechanism 7. A plurality of metal rollers 1 are connected between the relatively arranged fixed plates 2. The metal rollers 1 are arranged in parallel and at equal intervals. The two ends of the metal roller 1 are respectively rotatably connected to the two fixed plates 2. The two ends of the metal roller 1 extend out of the fixed plates 2 on both sides. The metal roller 1 is rotatably connected to the fixed plates 2 at both ends through bearings 21. The fixed plates 2 are provided with a plurality of bearing grooves 22 for mounting the bearings 21.

[0027] A roller drive mechanism 7 is installed on the outer surface of a fixed plate 2. This mechanism drives all metal rollers 1 to rotate synchronously. The roller drive mechanism 7 comprises a main drive shaft 71, a driving gear 72, and a driven gear 73. The main drive shaft 71 is positioned outside the fixed plate 2, parallel to the transmission direction. Multiple driving gears 72 are fixed to the main drive shaft 71, and driven gears 73 are fixed to the ends of the metal rollers 1. The driving gears 72 and driven gears 73 are meshed in a one-to-one relationship. The main drive shaft 71 drives the driven gears 73 and the metal rollers 1 to rotate via the driving gears 72. A coupling 74 is installed at the end of the main drive shaft 71, transmitting power to the main drive shaft 71. The coupling 74 is connected to an external motor, driving the main drive shaft 71 to feed the material.

[0028] Each metal roller 1 is provided with two ceramic ring assemblies 3. The ceramic ring assemblies 3 are detachably connected to the metal roller 1. The ceramic ring assemblies 3 can be freely adjusted in spacing and locked on the metal roller 1. All metal rollers 1 lock the ceramic ring assemblies 3 in the same position. Specifically, the ceramic ring assemblies 3 include a metal fixing ring 4, a ceramic ring 5, and an overlapping fixing block 6. The ceramic ring 5 is sleeved on the metal roller 1. The metal fixing ring 4 is fixed to the metal roller 1 closely against the ceramic ring 5. The metal fixing ring 4 and the metal roller 1 are clamped together. The metal fixing ring 4 and the ceramic ring 5 are locked together by the overlapping fixing block 6.

[0029] The ceramic ring 5 is an integrally formed part, comprising a cylindrical section 51 and a tapered section 52. The cylindrical section 51 abuts against the metal retaining ring 4, while the tapered section 52 is positioned inside the cylindrical section 51. The tapered surface of the tapered section 52 is capable of supporting the cell workpiece. A pin hole 511 is defined on the circumference of the cylindrical section 51 of the ceramic ring 5. The metal retaining ring 4 is provided with a screw hole 4131 adjacent to the pin hole. A fixing pin 61 is provided at the bottom of the overlapping fixing block 6. A countersunk hole 62 is defined in the overlapping fixing block 6. The fixing pin 61 is inserted into the pin hole 511. The countersunk hole 62 is positioned to correspond to the screw hole 4131. The countersunk hole 62 and the screw hole 4131 are securely connected via a screw 4131.

[0030] The metal fixing ring 4 is a split ring, and the metal fixing ring 4 includes an upper half ring 41 and a lower half ring 42. The two ends of the upper half ring 41 and the lower half ring 42 are opposite to each other to hold the metal roller rod 1 tightly. The opposite ends of the upper half ring 41 and the lower half ring 42 are respectively a locking end face 43 and an adjusting end face 44. The locking end face 43 is fixedly connected by bolts, and a gap 45 is provided between the adjusting end faces 44. The adjusting end faces 44 are connected by adjusting bolts (not shown in the figure). The adjusting bolts can adjust the distance of the gap 45, so that the upper half ring 41 and the lower half ring 42 can hold or loosen the metal roller rod 1. The locking end face 43 of the lower half ring 42 is provided with a positioning column 421 and a fastening screw hole 422, the adjusting end face 44 of the lower half ring 42 is provided with an adjusting screw hole 423, and both sides of the upper half ring 41 are respectively provided with bolt countersunk holes 412, and the lower ends of the bolt countersunk holes 412 are set on the locking end face 43 and the adjusting end face 44 of the upper half ring 41. The locking end face 43 of the upper half ring 41 is also provided with a positioning hole 411 corresponding to the positioning column 421, and the bolt countersunk holes 412 and the fastening screw holes 422 and the adjusting screw holes 423 on both sides are respectively connected by bolts.

[0031] The top of the upper half ring 41 also features a positioning groove 413, into which the countersunk section of the overlapping fixing block 6 fits. A screw hole 4131 is located at the center of the positioning groove 413, and the countersunk hole 62 of the overlapping fixing block 6 is fixedly connected to the screw hole 4131. The positioning groove 413 limits the position of the overlapping fixing block 6, enhancing the fixing effect between the overlapping fixing block 6 and the upper half ring 41. The upper half ring 41 and the lower half ring 42, which are clamped to the metal roller 1, act as a clamp. When the adjusting bolt is tightened through the bolt countersunk hole 412 and the adjusting screw hole 423, the gap 45 between the two adjustment end faces gradually decreases, thereby clamping the metal roller 1. Furthermore, because the metal fixing ring 4 is locked to the ceramic ring 5 via the overlapping fixing block 6, the ceramic ring 5 is fixed at this location. Since the metal fixing ring 4 can be clamped and fixed at any position on the metal roller 1, the spacing between the ceramic rings 5 ​​can be adjusted arbitrarily, eliminating the need for drilling holes in the metal roller 1 and preserving the integrity of the metal roller.

[0032] The working principle of the utility model is as follows: according to the size of the battery cell to be transported, the two ceramic ring assemblies 3 on the metal roller 1 are adjusted. In order to ensure the consistency of all metal rollers, the ceramic ring assembly 3 on one side can be kept stationary and the ceramic ring assembly 3 on the other side can be adjusted uniformly; when adjusting, the adjusting bolts connecting the adjusting end faces 44 of the upper half ring 41 and the lower half ring 42 are loosened upwards to widen the gap 45 between the two adjusting end faces 44, and the metal fixing ring 4 is loosened from the metal roller 1. After the ceramic ring 5 is moved to an appropriate position, the adjusting bolts are tightened downwards again to shorten the spacing so that the upper half ring 41 and the lower half ring 42 are clamped on the metal roller 1. Since one end of the overlapping fixing block 6 is fastened to the upper half ring 41 and the other end is locked with the ceramic ring 5 by a fixing pin 61, the ceramic ring 5 is relatively fixed to the metal fixing ring 4. When the metal roller 1 drives the metal fixing ring 4 to rotate, the ceramic ring 5 also rotates synchronously to transport the battery cell.

[0033] The above descriptions are merely some preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes and substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
