Description

Technical Field

[0001] The utility model relates to the technical field of laser induced sintering equipment, in particular to a material transmission device and a laser induced sintering system using the same. Background Art

[0002] In the photovoltaic industry, the feed inlet of laser-induced sintering equipment for solar cells is typically connected directly to the discharge outlet of upstream screen-printing equipment via a conveyor line. Because these conveyor lines typically transport the cells without a basket or wafer boat, if the downstream sintering equipment experiences an abnormality that causes it to cease operation, the upstream screen-printing equipment and conveyor line will not immediately cease operation. This can easily lead to cell blockage at the interface between the conveyor line and the sintering equipment, creating the risk of cell damage from collision.

[0003] To this end, some laser-induced sintering equipment in the prior art has added an emergency rejection section to the middle section of the conveyor line that connects to the upstream screen printing equipment. When the downstream sintering equipment stops operating due to an abnormal condition, the emergency rejection section is lifted and translated as a whole, or lifted and flipped upward with one side as the rotation center, so that the emergency rejection section is separated from the horizontal conveying surface of the conveyor line, and then the battery cells fall naturally into the emergency splicing box below the emergency rejection section due to gravity after they are separated from the conveyor line. This type of emergency rejection section that is separated from the conveyor line by lifting and translated as a whole or flipping upward on one side still has the risk of damage to the battery cells due to the high height difference between the conveyor line and the splicing box, and collisions between the cells in the box, during the process of naturally falling into the emergency splicing box below after the emergency rejection section is separated from the conveyor line.

Figure 1-4 And embodiments, the utility model is further described in detail.

[0069] Please also refer to Figure 1-4 The material transmission device provided by the present invention includes:

[0070] A horizontal transmission wheel group 1 and an adjustment transmission wheel group 2 are arranged in sequence; a driving device 4 is used to drive the horizontal transmission wheel group 1 and the adjustment transmission wheel group 2 to operate synchronously; a synchronous belt 3, which, under the drive of the driving device 4, passes through the horizontal conveying surface B of the horizontal transmission wheel group 1, the driving device 4, and the adjustment conveying surface C of the adjustment transmission wheel group 2 in sequence, and then returns to the horizontal conveying surface B of the horizontal transmission wheel group 1 through the driving device 4, thereby realizing the synchronous belt 3 to circulate synchronously between the horizontal transmission wheel group 1 and the adjustment transmission wheel group 2, and making the upward movement path of the synchronous belt 3 pass through the horizontal conveying surface B at the top of the horizontal transmission wheel group 1 and the adjustment conveying surface C at the top of the adjustment transmission wheel group 2 in sequence;

[0071] The adjusting device 6 is used to adjust the height of the adjusting transmission wheel group 2 at the downstream end (that is, the adjusting transmission wheel group 2 is away from the horizontal transmission wheel group 1 and close to the downstream device) to transport the target material to the downstream devices at different heights, thereby realizing emergency rejection of the target material in the middle of the transmission, and also realizing the sorting and transmission of the target material.

[0072] Please also refer to Figure 1-4 In this embodiment, the downstream device includes:

[0073] The emergency material receiving device 5 is provided below the downstream end of the adjusting transmission wheel group 2 (i.e., the end of the adjusting transmission wheel group 2 away from the horizontal transmission wheel group 1); the transmission target device, the horizontal feeding surface of the transmission target device for feeding is flush with the horizontal conveying surface B;

[0074] When the adjustment transmission wheel group 2 is adjusted at the downstream end to be flush with the horizontal transmission wheel group 1, the adjustment conveying surface C is flush with the horizontal conveying surface B. At this time, the synchronous belt 3 is used to convey the target material to the horizontal feed surface, and then the target material flows into the transmission target device through the horizontal feed surface;

[0075] When the transmission wheel group 2 at the downstream end is adjusted to be lower than the horizontal transmission wheel group 1, the conveying surface C is adjusted to be lower than the horizontal conveying surface B. At this time, the synchronous belt 3 is used to convey the target material to the emergency material receiving device 5.

[0076] Please also refer to Figure 1-4 In this embodiment, the material transmission device further includes:

[0077] Base 7, used to support the entire material conveying device;

[0078] The horizontal transmission wheel set 1 includes:

[0079] A fixed bracket 11 is provided on the base 7; a horizontal transmission assembly 12 is provided on the fixed bracket 11, and the horizontal transmission assembly 12 is away from the top of the base 7 to form the above-mentioned horizontal conveying surface B;

[0080] The adjustment transmission wheel set 2 includes:

[0081] The swing bracket 21 is spaced apart from the fixed bracket 11. The connecting end 2111 of the swing bracket 21 is rotatably connected to the base 7, and the height of the connecting end 2111 is flush with the fixed bracket 11. The connecting end 2111 is located at the upstream end of the adjustment transmission wheel group 2, and the free end 2112 of the swing bracket 21 opposite the connecting end 2111 is located at the downstream end of the adjustment transmission wheel group 2.

[0082] The adjusting transmission assembly 22 is provided on the swing bracket 21, and the adjusting transmission assembly 22 is away from the top of the base 7 to form the above-mentioned adjusting conveying surface C;

[0083] The adjusting device 6 is an adjusting cylinder, the fixed end 61 of the adjusting cylinder is hinged to the base 7, and the telescopic end 62 of the adjusting cylinder is hinged to the swing bracket 21;

[0084] By adjusting the cylinder to drive its telescopic end 62 to telescopically move relative to the fixed end 61, the free end 2112 of the swing bracket 21 (that is, the adjusting transmission wheel group 2 is located at the downstream end) is driven to swing up and down around the connecting end 2111 of the swing bracket 21 (that is, the adjusting transmission wheel group 2 is located at the upstream end), that is, the free end 2112 is driven to rotate around the connecting end 2111 as the rotation center, thereby driving the swing bracket 21 and the entire adjusting transmission wheel group 2 to swing up and down relative to the base 7; at the same time, in the process of adjusting the transmission wheel group 2 swinging up and down, the height of the connecting end 2111 of the swing bracket 21 (the adjusting transmission wheel group 2 is located at the upstream end) is kept flush with the horizontal transmission wheel group 1, and only the height of the free end 2112 (the adjusting transmission wheel group 2 is located at the downstream end) is changed; thereby changing the angle and height position of the adjusting conveying surface C relative to the horizontal conveying surface B, so that the adjusting conveying surface C switches between a horizontal posture flush with the horizontal conveying surface B and an inclined posture downwardly inclined near the emergency material receiving device 5 and lower than the horizontal conveying surface B.

[0085] When the adjustable transmission wheel assembly 2 swings until the adjustable conveying surface C is flush with the horizontal conveying surface B (at this time, the free end 2112 is flush with the horizontal transmission wheel assembly 1), the synchronous belt 3 is used to receive the target material from the upstream device to the horizontal conveying surface B, and transport the target material in sequence through the horizontal conveying surface B and the adjustable conveying surface C, that is, along the conveying direction D parallel to the horizontal direction, to the downstream device that is flush with the adjustable conveying surface C.

[0086] When the adjusting transmission wheel group 2 swings to the point where the adjusting conveying surface C is tilted downward relative to the horizontal conveying surface B and close to the emergency material receiving device 5 and is lower than the horizontal conveying surface B (at this time the free end 2112 is lower than the horizontal transmission wheel group 1), the synchronous belt 3 is used to transport the target material in sequence through the horizontal conveying surface B and the adjusting conveying surface C to the emergency material receiving device 5 below the end of the adjusting transmission wheel group 2 away from the horizontal transmission wheel group 1, so as to temporarily receive and store the target material in an emergency.

[0087] The material conveying device provided by the present invention has the following characteristics: when the adjustable conveying wheel assembly 2 swings until the adjustable conveying surface C is flush with the horizontal conveying surface B, the adjustable conveying wheel assembly 2, as part of the middle section of the transmission, connects between the horizontal conveying wheel assembly 1 and the downstream sintering device, thus achieving normal transmission function; when the adjustable conveying wheel assembly 2 swings until the adjustable conveying surface C tilts downward and is lower than the horizontal conveying surface B, the synchronous belt 3 can sequentially convey the target material through the horizontal conveying surface B and the adjustable conveying surface C to the emergency material receiving device 5 located below the downstream end of the adjustable conveying wheel assembly 2. Because the adjustable conveying surface C is tilted downward and lower than the horizontal conveying surface B at this time, the end of the adjustable conveying surface C away from the horizontal conveying wheel assembly 1 is at its lowest height and is closer to the emergency splicing box 52 below. This reduces the drop of the battery cell naturally falling into the splicing box after it leaves the end of the adjustable conveying surface C, thus preventing the battery cell from falling due to the large drop or colliding with other battery cells in the box after the emergency rejection section leaves the conveyor line, causing damage.

[0088] Please also refer to Figure 1-4 In this embodiment, the base 7 includes:

[0089] The base plate 71 is provided with a plurality of fixing holes for fastening to a fixed object or a supporting table; the support seat 72 is provided at the top of the base plate 71, and the above-mentioned fixed bracket 11 is provided on the support seat 72; the bearing seat 73 is provided at the top of the base plate 71 and is spaced apart from the support seat 72, and the connecting end 2111 of the swing bracket 21 is rotatably connected to the support seat 72; the fixed end 61 of the above-mentioned driving cylinder is hinged to the base plate 71, and the telescopic end 62 of the driving cylinder is hinged to the free end 2112 of the swing bracket 21 relative to the connecting end 2111.

[0090] Please also refer to Figure 1 、 2 4. In this embodiment, the horizontal transmission assembly 12 includes:

[0091] A pair of horizontal pulleys 121 are installed horizontally and spaced apart on the fixed bracket 11. The horizontal conveying surface B coincides with the top surface of the pair of horizontal pulleys 121 away from the base 7. The horizontal conveying surface B is the upward surface of the pair of horizontal pulleys 121 driving the synchronous belt 3 to run in the conveying direction D at the upper end away from the base 7 and remain parallel to the horizontal plane.

At the same time, the synchronous belt 3 passes through the horizontal conveying surface B, the tensioning wheel 8, and the adjusting conveying surface C in sequence, and then returns to the horizontal conveying surface B through the driving wheel 431, so as to realize the circular transmission of the synchronous belt 3 between the upward and downward movement paths, and the synchronous belt 3 is tensioned by the tensioning wheel 8 to prevent the synchronous belt 3 from loosening after long-term operation.

[0096] At the same time, the horizontal transmission component 12 and the adjustment transmission component 22 share a set of synchronous belts 3 (micro-elastic belts) for transmission, which can ensure that the movement speed of the synchronous belt 3 in the horizontal transmission wheel group 1 and the adjustment transmission wheel group 2 is the same, so that the synchronous belt 3 can synchronously transport the battery cells (target materials) along the conveying direction D in the horizontal transmission wheel group 1 and the adjustment transmission wheel group 2, avoiding the blockage phenomenon and the problems of powder shedding and deviation of the synchronous belt 3 caused by the different movement speeds of the synchronous belt 3 in the horizontal transmission wheel group 1 and the adjustment transmission wheel group 2.

[0105] A pair of mounting vertical plates 74 and two sets of tensioning pulleys 8 respectively mounted on the pair of mounting vertical plates 74 are symmetrically arranged on both sides of the base 7. The driving shaft 43 is mounted on one of the mounting vertical plates 74 or the two ends of the driving shaft 43 are respectively mounted on a pair of mounting vertical plates 74. A pair of driving pulleys 431 are arranged at intervals on the driving shaft 43, and the pair of driving pulleys 431 are respectively located between the corresponding mounting cantilevers 112 and the mounting swing arms 211. A pair of synchronous belts 3 are symmetrically (parallel and spaced) arranged on both sides of the base 7, and are respectively synchronously sleeved on the driving pulley 431 on the same side, the horizontal pulley 121 of the horizontal transmission assembly 12, the adjusting pulley 221 of the adjusting transmission assembly 22 and the tensioning pulley 8, so that the pair of synchronous belts 3 can synchronously transport the target material along the conveying direction D through the horizontal conveying surface B and the adjusting conveying surface C in sequence to the downstream device.

[0106] Please also refer to Figure 1 、 24. As a preferred implementation of this embodiment, the connecting block 212 includes a connecting sheet metal 2121 and a connecting cross bar 2122, and the connecting sheet metal 2121 and the connecting cross bar 2122 are spaced apart and connected between a pair of mounting swing arms 211.

[0107] See also Figure 1 、 2 As a preferred implementation scheme of this embodiment, one pair of relative horizontal pulleys 121 of a pair of horizontal transmission components 12 are respectively arranged at the opposite ends of a transmission shaft 122, and the pair of relative horizontal pulleys 121 are coaxially connected through the transmission shaft 122, so that the pair of relative horizontal pulleys 121 of a pair of horizontal transmission components 12 are synchronously driven by the synchronous belt 3.

[0108] In other embodiments (not shown in the figures), the horizontal transmission assembly 12 and the adjustment transmission assembly 22 can also be respectively provided with only one on the fixed bracket 11 and the swing bracket 21. In this case, the driving shaft 43 is only provided with a wider driving pulley 431, and a wider synchronous belt 3 is sleeved on a driving pulley 431, a wider horizontal pulley 121 of the horizontal transmission assembly 12 and a wider adjusting pulley 221 of the adjustment transmission assembly 22, so that the wider synchronous belt 3 can independently transport the target material.

[0109] Please also refer to Figure 1-4 In this embodiment, a plurality of mounting holes 711 are provided at intervals on the bottom plate 71, and the adjusting device 6 further includes the above-mentioned cylinder mounting seat 63. The fixed end 61 of the driving cylinder is hinged to the cylinder mounting seat 63, and the bottom of the cylinder mounting seat 63 is provided with a strip hole 631 that matches the mounting hole 711 and is parallel to the conveying direction D of the synchronous belt 3.

[0110] By passing connecting parts (such as screws or bolts) through the corresponding strip holes 631 and the mounting holes 711, the cylinder mounting seat 63 can be installed on the base in a manner that it can be adjusted forward and backward along the conveying direction D, so that the fixed end 61 at the bottom of the adjusting cylinder can be freely adjusted along with the cylinder mounting seat 63 on the bottom plate 71 in parallel with the conveying direction D of the synchronous belt 3. When the telescopic end 62 of the driving cylinder has a certain telescopic movement stroke relative to its fixed end 61, by changing the mounting position of the fixed end 61 on the bottom plate 71, the telescopic movement of the telescopic end 62 of the driving cylinder is adjusted under a certain telescopic movement stroke to drive the free end 2112 of the swing bracket 21 (the adjustment transmission wheel group 2 is located at the downstream end) to swing up and down, thereby adjusting the inclination angle and height position change range of the adjusting conveying surface C relative to the horizontal conveying surface B.

[0111] Please also refer to Figure 1 、 2 4. In this embodiment, the emergency material receiving device 5 includes:

[0112] The film box bracket 51 is arranged at an angle below the end of the adjusting transmission wheel group 2 away from the horizontal transmission wheel group 1 (that is, the free end 2112 of the swing bracket 21) in the conveying direction D; the emergency film box 52 is installed on the film box bracket 51 at an angle relative to the horizontal plane, and the higher end of the emergency film box 52 is close to and lower than the free end 2112 of the adjusting transmission wheel group 2, and the lower end of the emergency film box 52 is away from the free end 2112 of the adjusting transmission wheel group 2, so that the top inclined supporting surface 521 of the emergency film box 52 is transitionally connected with the downward inclined adjusting conveying surface C, and the height difference between the target material that detaches from the end of the adjusting conveying surface C and falls naturally and the inclined supporting surface 521 is reduced.

[0113] Please also refer to Figure 1 、 2 4. As a preferred embodiment of this embodiment, the cassette holder 51 includes:

[0114] The support vertical plate 511 is supported on a fixed ground or support table obliquely below the free end 2112 of the adjustment transmission wheel group 2 in the conveying direction D, and the support vertical plate 511 is provided with an arc-shaped clearance hole 5111; the film box card frame 512, the bottom of the film box card frame 512 is provided with a downwardly protruding connecting portion 5121, and the connecting portion 5121 is provided with a connecting hole 5122 matching the arc-shaped clearance hole 5111.

[0115] By means of connecting parts (such as screws or bolts) passing through the corresponding arc-shaped clearance holes 5111 and the connecting holes 5122, the film box frame 512 can be installed on the supporting vertical plate 511 so that it can swing up and down (the inclination angle can be adjusted) to adjust the inclination angle of the emergency splicing box 52 embedded in the inner side of the film box frame 512. Under the coordinated adjustment of the cylinder installation position and the inclination angle of the emergency splicing box 52, the downward inclination angle of the adjusted conveying surface C and the height at which the battery cell starts to fall from its end are more adapted to and close to the inclination angle of the emergency splicing box 52 and the highest point height of the emergency splicing box 52 for splicing, so that the battery cell falls into the emergency splicing box 52 with a small drop.

[0116] The utility model also provides a laser induced sintering system, comprising the above-mentioned material transmission device, and also comprising a sintering device (not shown in the figure) as the above-mentioned transmission target device;

[0117] On the feeding section of the sintering device on the horizontal feeding surface, the target material is a battery cell;

[0118] The above-mentioned horizontal transmission wheel group 1 is connected to the upstream screen printing device, and the feeding section is used to transport the target material (battery cell) from the adjusted conveying surface C through the horizontal feeding surface to the sintering device located in front of the feeding section when the above-mentioned adjusted conveying surface C is flush with the above-mentioned horizontal conveying surface B. The sintering section is used to perform laser induced sintering operations on the battery cells.

[0119] In this embodiment, the feeding device is a material conveying device that circulates the target material using a synchronous belt 3 .

[0120] The working principle of the laser induced sintering system provided by this utility model is as follows:

[0121] When the sintering device is operating normally, the telescopic end 62 of the adjusting cylinder is in an extended state and lifts up the adjusting transmission wheel group 2, so that the adjusting conveying surface C of the adjusting transmission wheel group 2 and the horizontal conveying surface B of the horizontal transmission wheel group 1 are on the same horizontal plane; when an emergency occurs in the sintering device, the telescopic end 62 of the adjusting cylinder retracts, so that the adjusting transmission wheel group 2 swings downward until the adjusting conveying surface C is close to the emergency material receiving device 5 and tilted downward and lower than the horizontal conveying surface B, so that the battery cells fall into the emergency splicing box 52 below with a small drop through the horizontal conveying surface B and the adjusting conveying surface C in turn, avoiding blockage.

[0122] The present invention further provides a material sorting system (not shown) comprising the aforementioned material conveying device and at least two sorting target devices serving as downstream devices of the aforementioned conveying device, each of the sorting target devices being located at a different height relative to the downstream end of the adjusting conveying wheel assembly 2. Adjusting device 6 adjusts the height of the downstream end of the adjusting conveying wheel assembly 2 (i.e., the end of the adjusting conveying wheel assembly 2 distal from the horizontal conveying wheel assembly 1 and proximal to the downstream device) to convey target materials to the sorting target devices at different heights, thereby achieving sorting and conveying of the target materials.

[0123] In this embodiment (not shown in the figure), the sorting target device includes a good product collection device and a defective product collection device, wherein the horizontal loading surface of the good product collection device for loading materials is flush with the horizontal conveying surface B, and the defective product collection device is located below the downstream end of the adjustment transmission wheel group 2;

[0124] When the transmission wheel set 2 is adjusted at the downstream end to be flush with the horizontal transmission wheel set 1, the conveying surface C is adjusted to be flush with the horizontal loading surface. At this time, the synchronous belt 3 is used to transport the target material to the horizontal loading surface, and then the target material flows into the good product collection device through the horizontal feeding surface;

[0125] When the transmission wheel group 2 at the downstream end is adjusted to be lower than the horizontal transmission wheel group 1, the conveying surface C is adjusted to be lower than the horizontal loading surface. At this time, the synchronous belt 3 is used to transport the target material to the defective product collection device, so that the material sorting system can perform sorting operations according to the quality of the target material.

[0126] In other embodiments (not shown in the figures), the sorting target device includes three or more collection devices at different heights, which can be used to collect different types of target materials. Its working principle is similar to that of the sorting target device including a good product collection device and a defective product collection device, and will not be repeated here.

[0127] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art should understand that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
