Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and in particular to a multi-suction cup suction device. Background Art

[0002] Crystalline silicon solar cells are developing rapidly. In the manufacturing process of mainstream crystalline silicon cells, the diffusion and deposition of silicon nitride anti-reflection films require the loading and unloading of cells. For loading and unloading, most production lines will choose automated equipment, but automated equipment is expensive and requires professional equipment personnel to operate. Once a failure occurs, the maintenance time is long, which affects the process progress and delays the delivery date. For some debugging and small-batch experiments, suction pens are generally used for loading and unloading, but the suction pens currently used can only load and unload one battery at a time, which is time-consuming and affects the progress of the experiment.

DETAILED DESCRIPTION

[0055] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0056] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0057] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0058] To facilitate understanding of the multi-suction cup suction device provided in the embodiment of the present application, its application scenario is first described. The multi-suction cup suction device is used in the process of placing a silicon wafer into a graphite boat or a quartz boat, and in the process of removing a silicon wafer from a graphite boat or a quartz boat. The multi-suction cup suction device is used as a device for sucking silicon wafers or battery cells and capable of transferring silicon wafers or battery cells. Automated equipment is used in the prior art, but the cost of automated equipment is high and requires professional equipment personnel to operate. Once a failure occurs, the maintenance time is long, which affects the process progress and delays the delivery date. Suction pens are generally selected for loading and unloading of some debugging and small-batch experiments, but the suction pens currently used can only load and unload one battery at a time, which has a high time cost and affects the progress of the experiment. To this end, the embodiment of the present application provides a multi-suction cup suction device to reduce the cost of use and improve work efficiency. The following is a detailed description of it in conjunction with specific drawings and embodiments.

[0059] For reference Figure 1 and Figure 2 , Figure 1 The structure diagram of the piston-type multi-suction cup suction device provided in the embodiment of the present application is shown. Figure 2 A schematic diagram of the structure of the suction cups in the multi-suction cup suction device provided in an embodiment of the present application is shown.

[0060] The embodiment of the present application illustrates a multi-suction cup suction device. The multi-suction cup suction device includes a suction and exhaust mechanism 1, a gas circulation pipeline 2 and a suction cup 3 connected to each other. The interior of the suction and exhaust mechanism 1 is connected to the interior of the gas circulation pipeline 2 and the interior of the suction cup 3.

[0061] Specifically, the suction cup 3 has a cavity 33 and a connection port 31 and an adsorption port 32 connected to the cavity 33. The function of the connection port 31 is to connect the cavity 33 with the inner cavity of the gas circulation pipe 2 through the connection port 31, and the function of the adsorption port 32 is to generate an adsorption force to fix the object to be adsorbed. It should be noted that the object to be adsorbed in the embodiment of the present application specifically refers to an object that can be fixed by the adsorption force generated by the adsorption port 32, such as: a chip, a silicon wafer, a battery cell, etc.

[0062] During the operation of the multi-suction cup suction device, the suction and exhaust mechanism 1 can extract gas from the cavity 33 through the gas flow pipe 2 to generate a pressure difference at the suction port 32, so that the object to be suctioned is fixed at the suction port 32. Then, the user can put the object to be suctioned into the graphite boat or the quartz boat or remove the silicon wafer from the graphite boat or the quartz boat through the multi-suction cup suction device without dropping the object to be suctioned.

[0063] During the operation of the multi-suction cup suction device, after the user places the object to be adsorbed into the graphite boat or the quartz boat through the multi-suction cup suction device, the user can also use the suction and exhaust mechanism 1 to provide gas to the cavity 33 through the gas circulation pipe 2 to eliminate the air pressure difference at the suction port 32, so that the object to be adsorbed is released from the suction port 32.

[0064] A gas on-off component 4 is also provided between the suction cup 3 and the gas flow pipe 2. The gas on-off component 4 is used to control the connection and disconnection between the cavity 33 and the inner cavity of the gas flow pipe 2. The specific structure of the gas on-off component 4 is not limited in the embodiment of the present application, and any structure that can control the on-off of the gas can be used, such as a stop valve, a sliding column valve, a slide valve, etc. In the embodiment of the present application, the specific structure of the gas on-off component 4 is a slide valve as an example for description.

[0065] refer to Figure 3 , Figure 3 A schematic structural diagram of a gas on-off component in a multi-suction cup suction device provided in an embodiment of the present application is shown.

[0066] By providing a gas on-off component 4 between the suction cup 3 and the gas circulation pipeline 2, the user can selectively open or close the gas flow between the cavity 33 of the suction cup 3 and the inner cavity of the gas circulation pipeline 2 according to work needs.

[0067] In the embodiment of the present application, there are multiple suction cups 3. In the embodiment of the present application, multiple suction cups 3 specifically refer to two or more suction cups 3, such as two suction cups 3, three suction cups 3, five suction cups 3, eight suction cups 3, ten suction cups 3, eleven suction cups 3, etc. In the embodiment of the present application, the number of suction cups 3 is eleven as an example for description.

[0068] Specifically, the cavity 33 of each suction cup 3 is connected to the gas flow pipe 2 through its corresponding connection port 31 .

[0069] In the above technical solution, by arranging multiple suction cups 3 connected to the gas circulation pipe 2, the user can simultaneously put multiple items to be adsorbed into the graphite boat or quartz boat, and can simultaneously remove multiple items to be adsorbed from the graphite boat or quartz boat.

[0070] A gas on-off component 4 is provided between the suction cup 3 and the gas circulation pipeline 2, so that the user can selectively open or close the gas flow between the cavity 33 of a part of the suction cup 3 and the inner cavity of the gas circulation pipeline 2 according to the number of the parts to be adsorbed.

[0071] In the embodiment of the present application, the air intake and exhaust mechanism 1 comprises a piston cylinder 11 and a piston 12. Specifically, the piston 12 is disposed inside the piston cylinder 11.

[0072] In the embodiment of the present application, the suction and exhaust mechanism 1 further includes a handle 13. Specifically, the handle 13 is connected to the piston 12.

[0073] During the operation of the air intake and exhaust mechanism 1 , the piston 12 slides in the piston cylinder 11 , and the piston 12 divides the piston cylinder 11 into a first chamber 111 and a second chamber 112 along a first direction. Figure 1 , the first direction is shown as the sliding direction of the piston 12 .

[0074] Specifically, one end of the handle 13 extends into the first chamber 111 and is connected to the piston 12 to push the piston 12 to slide along the first direction.

[0075] The second chamber 112 is communicated with the inner cavity of the gas flow pipe 2 .

[0076] During the process that the piston 12 slides in the piston cylinder 11 along the first direction toward the connection position between the gas circulation pipeline 2 and the second chamber 112, the volume of the first chamber 111 gradually increases, and the volume of the second chamber 112 gradually decreases, so that the gas inside the second chamber 112 enters the inner cavity of the gas circulation pipeline 2, and then is discharged from the suction port 32 through the cavity 33 of the suction cup 3. At this time, there is no suction force at the suction port 32.

[0077] When the piston 12 slides in the piston cylinder 11 along the first direction toward the connection position away from the gas circulation pipe 2 and the second chamber 112, the volume of the first chamber 111 gradually decreases, and the volume of the second chamber 112 gradually increases, and then the gas enters the cavity 33 of the suction cup 3 through the suction port 32, and then enters the interior of the second chamber 112 through the inner cavity of the gas circulation pipe 2. At this time, a pressure difference is generated at the suction port 32, and the suction port 32 has an adsorption force on the object to be adsorbed.

[0078] For reference Figure 4 and Figure 5 , Figure 4 The structure diagram of the first spring plunger in the multi-suction cup suction device provided in the embodiment of the present application is shown. Figure 5 A schematic structural diagram of the first groove in the multi-suction cup suction device provided in an embodiment of the present application is shown.

[0079] In the embodiment of the present application, the suction and exhaust mechanism 1 further includes a fixing seat 14. The fixing seat 14 in the embodiment of the present application specifically refers to the base of the multi-suction cup suction device, which is used to install components such as the suction and exhaust mechanism 1, the gas flow pipe 2 and the suction cup 3. In the embodiment of the present application, the installation bases of the various components in the multi-suction cup suction device are collectively referred to as the fixing seat 14. In actual use, the specific structure of the fixing seat 14 can be adaptively adjusted according to the components to be installed.

[0080] Specifically, a first spring plunger 131 is provided on the side of the handle 13 facing the fixing seat 14. It should be noted that the first spring plunger 131 is also called a ball plunger, or a positioning bead, or a positioning column. A spring is installed inside the first spring plunger 131, and the preload force is adjusted by controlling the screw-in depth to achieve the positioning function.

[0081] A plurality of first grooves 141 are arranged at intervals along a first direction on one side of the fixing seat 14 facing the handle 13. The first grooves 141 are used to accommodate or fix other components.

[0082] Specifically, the first spring plunger 131 can slide into or out of any first groove 141 along the first direction.

[0083] Since the multiple first grooves 141 are arranged at intervals along the first direction and are parallel to the sliding direction of the piston 12 in the piston cylinder 11, each first groove 141 corresponds to a gear position. When the first spring plunger 131 slides into different first grooves 141, the piston 12 will also move to different positions along the first direction. Correspondingly, the internal volume of the second chamber 112 is different, and the volume of the gas inside the second chamber 112 is different. When the piston 12 slides along the first direction toward the side of the handle 13, the internal volume of the second chamber 112 gradually increases, and a large air pressure difference is generated at the position of the suction port 32, so the suction cup 3 connected to the second chamber 112 can adsorb parts to be adsorbed of different specifications and sizes.

[0084] The first groove 141 close to the connection position between the gas circulation pipe 2 and the second chamber 112 along the first direction corresponds to a higher gear position. When the first spring plunger 131 slides into the first groove 141 with a higher gear position, the volume inside the second chamber 112 is lower, and the volume of the gas discharged from the second chamber 112 is larger. At this time, when the user applies a force to the handle 13 away from the connection position between the gas circulation pipe 2 and the second chamber 112 along the first direction, when the first spring plunger 131 slides out from the first groove 141 with a higher gear position, the suction cup 3 connected to the second chamber 112 generates a larger adsorption force.

[0085] For reference Figure 6 and Figure 7 , Figure 6 The structure diagram of the second spring plunger in the multi-suction cup suction device provided in the embodiment of the present application is shown. Figure 7 A schematic diagram of the structure of the second groove in the multi-suction cup suction device provided in an embodiment of the present application is shown.

[0086] In the embodiment of the present application, the circumferential outer surface of the piston 12 is provided with a second spring plunger 121. It should be noted that the second spring plunger 121 is also called a ball plunger, or a positioning bead, or a positioning column. A spring is installed inside the second spring plunger 121, and the preload force is adjusted by controlling the screw-in depth to achieve the positioning function.

[0087] The inner side wall of the piston cylinder 11 is provided with a plurality of second grooves 113 at intervals along the first direction, wherein the second grooves 113 are used to accommodate or fix other components.

[0088] Specifically, the second spring plunger 121 can slide into or out of any second groove 113 along the first direction.

[0089] Since a plurality of second grooves 113 are arranged at intervals along the first direction on the inner wall of the piston cylinder 11, which are parallel to the sliding direction of the piston 12 in the piston cylinder 11, each second groove 113 corresponds to a gear position. When the second spring plunger 121 slides into different second grooves 113, the piston 12 will also move to different positions along the first direction. Correspondingly, the internal volume of the second chamber 112 is different, and the volume of the gas inside the second chamber 112 is different. When the piston 12 slides along the first direction toward the handle 13, the internal volume of the second chamber 112 gradually increases, and a large air pressure difference is generated at the position of the suction port 32, so the suction cup 3 connected to the second chamber 112 can adsorb parts to be adsorbed of different specifications and sizes.

[0090] The gear position corresponding to the second groove 113 close to the connection position between the gas circulation pipeline 2 and the second chamber 112 along the first direction is higher. When the second spring plunger 121 slides into the second groove 113 with a higher gear position, the volume inside the second chamber 112 is lower, and the volume of the gas discharged from the second chamber 112 is larger. At this time, when the user applies a force to the handle 13 away from the connection position between the gas circulation pipeline 2 and the second chamber 112 along the first direction, when the second spring plunger 121 slides out from the second groove 113 with a higher gear position, the suction cup 3 connected to the second chamber 112 generates a larger adsorption force.

[0091] In the embodiment of the present application, the interior of the second chamber 112 has a bottom wall 1121 facing the piston 12 along the first direction, and the piston 12 has an extrusion surface 122 facing the bottom wall 1121 along the first direction.

[0092] Specifically, an elastic component 1122 that can be extended and retracted along the first direction is provided between the extrusion surface 122 and the bottom wall 1121. The specific structure of the elastic component 1122 is not limited in the embodiment of the present application, and it can be a structure with elasticity, such as a spring, a rubber column, etc. In the embodiment of the present application, the specific structure of the elastic component 1122 is a spring as an example for description.

[0093] By arranging an elastic component 1122 that can be extended and retracted along the first direction between the extrusion surface 122 and the bottom wall 1121, when the piston 12 slides along the first direction toward the side close to the connection position between the gas circulation pipeline 2 and the second chamber 112, the extrusion surface 122 and the bottom wall 1121 squeeze the elastic component 1122, so that the elastic component 1122 is compressed and accumulates elastic potential energy. After the user no longer applies a force to the handle 13 along the first direction close to the gas circulation pipeline 2, the elastic potential energy accumulated by the compression of the elastic component 1122 is converted into elastic force acting on the extrusion surface 122, and the piston 12 slides along the first direction toward the side away from the connection position between the gas circulation pipeline 2 and the second chamber 112, and the suction cup 3 connected to the second chamber 112 generates an adsorption force.

[0094] refer to Figure 8 , Figure 8 A schematic structural diagram of an airbag-type multi-suction cup suction device provided in an embodiment of the present application is shown.

[0095] In the embodiment of the present application, the air intake and exhaust mechanism 1 includes an airbag 15. The airbag 15 is used to change the air pressure inside the airbag 15 and the air pressure inside other components connected to the airbag 15 by stretching or compressing, so that the airbag 15 and other components connected to the airbag 15 can achieve air intake or exhaust.

[0096] Specifically, the airbag 15 can be stretched or compressed along the second direction, and a sleeve 18 is provided on the outer peripheral surface of the airbag 15. Figure 8 , the second direction is shown as the extension direction of the sleeve 18 .

[0097] In the embodiment of the present application, the air intake and exhaust mechanism 1 further comprises a pressure rod 16. The pressure rod 16 is used to squeeze the airbag 15 or release the squeezing of the airbag 15.

[0098] Specifically, the pressure rod 16 is connected to the airbag 15, and a portion of the pressure rod 16 protrudes from the sleeve 18. Specifically, the pressure rod 16 protrudes from the sleeve 18 in the embodiment of the present application, which means that a portion of the pressure rod 16 close to the airbag 15 along the second direction is placed inside the sleeve 18, and a portion of the pressure rod 16 away from the airbag 15 along the second direction is placed outside the sleeve 18. The user can indirectly apply force to the airbag 15 by pressing the portion of the pressure rod 16 placed outside the sleeve 18, so as to change the air pressure inside the airbag 15.

[0099] In the embodiment of the present application, the air intake and exhaust mechanism 1 further includes a pressure plate 17. Specifically, the pressure plate 17 is located between the airbag 15 and the pressure rod 16 to disperse the squeezing force applied by the pressure rod 16 and act on the airbag 15, so that the side of the airbag 15 facing the pressure rod 16 is subjected to an equal squeezing force, and even if there is an error, it should be within the allowable error range. On the contrary, if there is no pressure plate 17 to disperse the squeezing force applied by the pressure rod 16 and act on the airbag 15, then the side of the airbag 15 facing the pressure rod 16 will be partially subjected to squeezing force, and as the air intake and exhaust mechanism 1 is used, the position where the side of the airbag 15 facing the pressure rod 16 is partially subjected to squeezing force is prone to damage.

[0100] For reference Fig. 9 and Fig.10 , Fig. 9 The schematic diagram of the structure of the third spring plunger in the multi-suction cup suction device provided in the embodiment of the present application is shown. Fig.10 A schematic diagram of the structure of the third groove in the multi-suction cup suction device provided in an embodiment of the present application is shown.

[0101] In the embodiment of the present application, a plurality of third grooves 181 are arranged at intervals along the second direction on the inner wall of the sleeve 18. In the embodiment of the present application, the plurality of third grooves 181 specifically refers to two or more third grooves 181, such as two third grooves 181, three third grooves 181, four third grooves 181, five third grooves 181, etc. In the embodiment of the present application, the number of the third grooves 181 is three as an example for description.

[0102] A third spring plunger 171 is arranged on the outer peripheral surface of the pressure plate 17. The third spring plunger 171 is used to be clamped in the third groove 181.

[0103] The third spring plunger 171 can slide into or out of any third groove 181 along the second direction.

[0104] Since the plurality of third grooves 181 are arranged at intervals along the second direction, parallel to the direction of extension and compression of the airbag 15, each third groove 181 corresponds to a gear position. When the third spring plunger 171 slides into different third grooves 181, the pressure plate 17 will also move to different positions along the second direction. Accordingly, the volume of the gas inside the airbag 15 is different if the degree of extension and compression of the airbag 15 is different. When the airbag 15 is extended, the air pressure inside the airbag 15 is different, so the suction cup 3 connected to the airbag 15 can adsorb parts to be adsorbed of different specifications and sizes.

[0105] Among them, the third groove 181 close to the connection position between the gas circulation pipeline 2 and the second chamber 112 along the second direction corresponds to a higher gear position. When the third spring plunger 171 slides into the third groove 181 with a higher gear position, the pressure plate 17 squeezes the airbag 15, so that the degree of compression of the airbag 15 is higher, and the volume of the gas discharged from the airbag 15 is larger. At this time, when the user applies a force to the pressure rod 16 away from the connection position between the gas circulation pipeline 2 and the second chamber 112 along the second direction, when the third spring plunger 171 slides out from the third groove 181 with a higher gear position, the suction cup 3 connected to the airbag 15 generates a larger adsorption force.

[0106] refer to Fig.11 , Fig.11 A schematic diagram of the structure of a slideway in a multi-suction cup suction device provided in an embodiment of the present application is shown.

[0107] In the embodiment of the present application, a slideway 182 extending along the second direction is provided on the inner wall of the sleeve 18 , and a protrusion 172 is provided on the outer peripheral surface of the pressure plate 17 .

[0108] The protrusion 172 slides in the slideway 182, so that when the user pushes the pressure rod 16, the pressure plate 17 can slide along the second direction, reducing the rotation amplitude of the pressure plate 17 and the airbag 15 connected to the pressure plate 17. On the contrary, if the pressure plate 17 and the airbag 15 connected to the pressure plate 17 rotate at a large amplitude during the operation of the air intake and exhaust mechanism 1, the airbag 15 may be damaged.

[0109] In the embodiment of the present application, multiple suction cups 3 are detachably connected to the gas circulation pipe 2. In order to improve the sealing performance of the connection position between the suction cup 3 and the gas circulation pipe 2, the suction cup 3 and the gas circulation pipe 2 can be threadedly connected, and a sealing ring can be provided at the position where the suction cup 3 and the gas circulation pipe 2 are threadedly connected.

[0110] Specifically, the gas on-off component 4 is arranged on the gas circulation pipeline 2 .

[0111] In the embodiment of the present application, a plurality of suction cups 3 are connected to the gas circulation pipeline 2 at intervals. By setting a plurality of suction cups 3 connected to the gas circulation pipeline 2 at intervals, the plurality of suction cups 3 can be inserted into the intervals between the plurality of objects to be adsorbed, and each suction cup 3 adsorbs one object to be adsorbed, so that the multi-suction cup suction device can adsorb a plurality of objects to be adsorbed at the same time, thereby improving the working efficiency.

[0112] Specifically, the suction ports 32 are opened on the surface of the suction cup 3 along the third direction, and the opening direction of the suction ports 32 set on the surface of each suction cup 3 is consistent with the opening direction of the suction ports 32 set on the surfaces of other suction cups 3 .

[0113] The third direction is the arrangement direction of the plurality of suction cups 3 .
