Description

Technical Field

[0001] This invention relates to the field of glass auxiliary production equipment, and more particularly to a transfer-type lifting device. Background Technology

[0002] Glass is one of the important components of many production equipment, automobiles and other large mechanical devices. Depending on the different usage requirements, glass needs to be processed to different degrees. For example, before the edge-wrapping process (or the application of adhesive strips) of the sunroof glass of an automobile, a coating material needs to be applied to the glass surface. The edge-wrapping operation can only be carried out after the coating material has dried and cooled.

[0003] In the existing technology, taking sunroof glass as an example, a chain-type lifting device can be used to carry and slowly transfer sunroof glass pieces one by one upwards. During the process of each sunroof glass piece being lifted from the lowest point to the highest point of the chain-type lifting device, the coating material can be dried and cooled. After being lifted to the highest point, it can enter the next process flow, such as being adsorbed by a suction cup and transferred to the edge-wrapping production line for edge wrapping.

[0004] However, existing chain-type lifting devices require multiple gears and chains to work together to lift and transmit the glass. This mechanism is complex and has a complicated assembly process. Furthermore, the chains can stretch after prolonged use, causing increased chain transmission errors. Ultimately, this makes it difficult to accurately lift the product to be moved (such as sunroof glass) to the designated position.

[0005] It is evident that existing technologies suffer from problems such as complex structures, complicated assembly processes, and poor accuracy in lifting positions. Summary of the Invention

[0006] This invention provides a transmission-type lifting device to solve the problems of complex structure, complicated assembly process, and poor accuracy of lifting position in the prior art.

[0007] The present invention provides a transmission-type lifting device, including at least one lifting component; the at least one lifting component includes a first column and a second column, the first column being drivable to slide along the side wall of the second column.

[0008] At least one lifting assembly also includes a first link and a plurality of first brackets, the plurality of first brackets being spaced apart along the extension direction of the first column, the first ends of each first bracket being connected together by the first link, and the second ends of the first brackets being used to support the product to be moved.

[0009] Each first bracket is rotatably connected to the side wall of the first column, and is able to rotate its second end around its rotation center between the first supported position and the non-supported position under the action of external force.

[0010] The transmission-type lifting device of the present invention abandons the gear and chain transmission mechanism in the traditional technical solution. It uses the first column that slides along the side wall of the second column to realize the lifting or lowering of the product to be moved. The structure is simple and easy to install. Furthermore, since the present invention does not rely on chain transmission, it also avoids the transmission error problem after long-term use of the chain, and the lifting position accuracy is high.

[0011] Furthermore, the present invention, through multiple first brackets and first connecting rods set on the first column, can support multiple products to be moved (such as sunroof glass) to be raised or lowered simultaneously. The structure is compact and, while ensuring the accuracy of the lifting position, also takes into account the transmission efficiency of the products to be moved (or can be understood as being able to lift and transfer multiple products to be moved simultaneously).

[0012] Optionally, at least one lifting assembly further includes a second link and a plurality of second brackets, the plurality of second brackets being spaced apart along the extension direction of the second column, the first ends of each second bracket being connected together by the second link, and the second ends of the second brackets being used to support the product to be moved.

[0014] When the first bracket is in the first supporting position and supporting the product to be moved as it rises, the second bracket is in the clearance position.

[0015] The avoidance position is configured such that the second end of the second bracket rotates toward the second column to a position where it does not contact the product to be moved.

[0016] With the above structure, the embodiments of the present invention, through multiple first brackets on the side wall of the first column and multiple second brackets on the side wall of the second column, enable the product to be moved to be supported by the first brackets when being lifted and by the second brackets when being lowered. Alternatively, it can be understood that the transfer-type lifting device of the embodiments of the present invention enables the product to be moved to be supported by the first brackets or the second brackets in turn during the lifting or lowering process, and the first brackets and the second brackets can avoid mutual interference by rotating to the corresponding positions.

[0017] Optionally, at least one lifting component may further include a first limiting member and a second limiting member;

[0018] The first limiting member is provided on the side wall of the first column. When the second end of the plurality of first brackets rotates to the first supporting position, at least one of the plurality of first brackets abuts against the first limiting member.

[0022] The embodiments of the present invention, by providing edge strips on the first column and / or the second column, help to quickly position the product to be moved on the first bracket or the second bracket.

[0023] Optionally, the edge guard strip is located on the second column, and the transfer-type lifting device also includes an adjusting component connected to the edge guard strip and the second column. The adjusting component is used to adjust the distance between the side walls of the edge guard strip and the second column to accommodate products of different sizes to be moved.

[0024] Optionally, at least one lifting component may be multiple, and multiple lifting components may include multiple lifting component groups;

[0025] Each lifting assembly group includes a first lifting assembly and a second lifting assembly, which are spaced apart along one edge of the product to be moved.

[0026] The first column in the first lifting assembly and the first column in the second lifting assembly are arranged facing each other, while the second column in the first lifting assembly and the second column in the second lifting assembly are arranged opposite each other.

[0027] Optionally, the transmission lifting device also includes a drive cylinder, which connects to and drives the first column in the first lifting assembly and the first column in the corresponding second lifting assembly.

Therefore, they should not be construed as limiting the present invention.

[0044] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0045] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0046] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0047] This invention can be applied to various production lines, such as automotive parts production lines, large machinery production lines, etc. For example, it can be applied to the coating process of sunroof glass in automobiles before edge banding (or adhesive strip application). The sunroof glass is raised or lowered to the desired position using the transfer-type lifting device of this invention. In one embodiment, the sunroof glass pieces can be carried and slowly transferred upwards piece by piece using the transfer-type lifting device. During the process of each sunroof glass piece being raised from the lowest to the highest point of the transfer-type lifting device, the coating material can be dried and cooled. After being raised to the highest point, it can proceed to the next process flow, for example, it can be transferred to the edge banding production line by suction cups for edge banding. In this invention, the type of product to be moved is not limited; it can be glass, such as automotive sunroof glass, or other types of glass, or other sheet-like, plate-like, or other shaped components.

[0048] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the lifting component in the transfer-type lifting device according to an embodiment of the present invention. The present invention provides a transfer-type lifting device 1, including at least one lifting component 10.

[0049] At least one lifting component can be understood as the number of lifting components being one or more. One lifting component 10 includes a first column 11 and a second column 12, the first column 11 being drivable to slide along the side wall of the second column 12;

[0050] like Figure 1 As shown, a lifting assembly also includes a first connecting rod 13 and a plurality of first brackets 111. The plurality of first brackets 111 are spaced apart along the extension direction (or height direction) of the first column 11. The first ends of each first bracket 111 are connected together by the first connecting rod 13, and the second ends of the first brackets 111 are used to support the product to be moved (e.g., sunroof glass). In one embodiment, the second end of the first bracket 111 has a storage groove 1110, and the edge of the product to be moved (e.g., sunroof glass) can be placed in the storage groove 1110, so that the product to be moved can be placed more stably on the first bracket 111.

[0051] like Figure 1 As shown, each first bracket 111 is rotatably connected to the side wall of the first column 11, and can rotate its second end around its rotation center between a first supporting position and a non-supporting position under the action of external force. In one embodiment, the first bracket 111 is rotatably connected to the first column 11 via a pivot 112, and the aforementioned first connecting rod 13 enables all the connected first brackets to rotate synchronously.

[0052] The first support position can be, for example, as follows: Figure 1As shown, the first bracket 111 extends in a horizontal direction, or it can be understood that the first bracket 111 rotates in a direction away from the first column 11 to a position approximately perpendicular to the first column 11.

[0053] The non-supporting position can be understood as the first bracket 111 rotating to a position away from the aforementioned first supporting position. In one embodiment, when the product to be moved is placed at the second end of the first bracket 111, the first bracket 111 rotates towards the first column 11 to a position approximately close to the first column 11. In another embodiment, the weight of the bracket segment between the rotation center and the first end of the first bracket 111 is greater than the weight of the bracket segment between the rotation center and the second end. Therefore, when the product to be moved is placed at the second end of the first bracket 111, gravity will cause the first bracket 111 to rotate around its rotation center to the aforementioned non-supporting position. In other alternative embodiments, the non-supporting position can also be another position at a different angle to the first column.

[0054] The transmission-type lifting device of the present invention abandons the gear and chain transmission mechanism in the traditional technical solution. It uses the first column 11 that slides along the side wall of the second column 12 to lift or lower the product to be moved. The structure is simple and easy to install. Furthermore, since the present invention does not rely on chain transmission, it also avoids the error problem after long-term use of the chain, and the lifting position accuracy is high.

[0055] Furthermore, the present invention, through multiple first brackets 111 and first connecting rods 13 set on the first column 11, can support multiple products to be moved (such as sunroof glass) to be raised or lowered simultaneously. The structure is compact and, while ensuring the accuracy of the lifting position, also takes into account the transmission efficiency of the products to be moved (or can be understood as being able to lift and transfer multiple products to be moved simultaneously).

[0056] In one implementation, please refer to Figure 1 and combined Figure 2 and Figure 3 understand, Figure 2 This is a partial three-dimensional structural diagram of the transfer lifting device in an embodiment of the present invention. Figure 3 This is a three-dimensional structural diagram of the product to be moved placed on the first bracket in an embodiment of the present invention.

[0057] At least one lifting assembly 10 also includes a second link 14 and a plurality of second brackets 121. The plurality of second brackets are spaced apart along the extension direction (or can be understood as the height direction) of the second column 12. The first end of each second bracket 121 is connected together by the second link 14. The second end of the second bracket 121 is used to support the product to be moved. In one embodiment, the second end of the second bracket 121 has a storage groove 1210. The edge of the product to be moved (e.g., sunroof glass) can be placed in the storage groove 1210 so that the product to be moved can be placed more stably on the second bracket 121.

[0058] Each second bracket 121 is rotatably connected to the side wall of the second column 12, and is capable of rotating its second end around its rotation center between a second supporting position and a clearance position under the action of an external force. In one embodiment, the second bracket 121 is rotatably connected to the second column 12 via a pivot 122.

[0059] When the first bracket 111 is in the first supporting position and supporting the product to be moved as it rises, the second bracket 121 is in the avoidance position. The avoidance position is configured such that the second end of the second bracket 121 rotates toward the second column 12 to a position where it does not contact the product to be moved (e.g., ...). Figure 3 (As shown).

[0060] The second bracket 121 located at the second support position may, for example, be parallel to the first bracket 111 located at the first support position. In other alternative embodiments, the two may not be parallel.

[0061] In this embodiment of the invention, the transfer-type lifting device 1 uses multiple first brackets 111 on the side wall of the first column 11 and multiple second brackets 121 on the side wall of the second column 12 to enable the product to be moved (e.g., a sunroof glass) to be supported by the first brackets 111 when being lifted and by the second brackets 121 when being lowered. Alternatively, it can be understood that the transfer-type lifting device 1 of this embodiment of the invention enables the product to be moved to be supported by the first brackets 111 or the second brackets 121 in turn during the lifting or lowering process, and the first brackets 111 and the second brackets 121 can avoid mutual interference by rotating to the corresponding positions.

[0062] In one embodiment, the second bracket 121 is similar in shape and rotation method to the first bracket 111, and will not be described in detail here.

[0063] In one implementation, such as Figure 2As shown, at least one lifting assembly 10 further includes a first limiting member 15 and a second limiting member 16. The first limiting member 15 is disposed on the side wall of the first column 11. When the second ends of the plurality of first brackets 111 rotate to the first supporting position, at least one of the plurality of first brackets 111 abuts against the first limiting member 15. In one embodiment, the first limiting member 15 is positioned near the first bracket 111 that is furthest from the ground. In other alternative embodiments, it may be positioned near other first brackets. The second limiting member 16 is disposed on the side wall of the second column 12. When the second ends of the plurality of second brackets 121 rotate to the second supporting position, at least one of the plurality of second brackets 121 abuts against the second limiting member 16. In one embodiment, the second limiting member 16 is positioned near the second bracket 121 that is furthest from the ground. In other alternative embodiments, it may be positioned near other second brackets.

[0064] In one embodiment, at least one lifting component may be multiple, and the multiple lifting components may include multiple lifting component groups, such as... Figure 2 As shown, the multiple lifting components include two lifting component groups (lifting component group 10A and lifting component group 10B). In other alternative embodiments, there may be three, four, or more lifting component groups. The number of lifting component groups can be selected as needed based on the size and shape of the product to be moved.

[0065] Each lifting assembly group includes a first lifting assembly and a second lifting assembly. For example, lifting assembly group 10A includes a first lifting assembly 101 and a second lifting assembly 102, and lifting assembly group 10B includes a first lifting assembly 103 and a second lifting assembly 104.

[0066] For specific details, please refer to... Figure 3 It is understood that the first lifting component and the second lifting component are spaced apart along one edge of the product to be moved. For example, the first lifting component 101 and the second lifting component 102 are spaced apart along the first edge of the product to be moved, and the first lifting component 103 and the second lifting component 104 are spaced apart along the second edge of the product to be moved. The first edge and the second edge are two opposite edges of the product to be moved.

[0067] Furthermore, the first column 11 in the first lifting assembly (e.g., the first lifting assembly 103) and the first column 11 in the second lifting assembly (e.g., the second lifting assembly 104) are arranged facing each other, and the second column 12 in the first lifting assembly (e.g., the first lifting assembly 103) and the second column 12 in the second lifting assembly (e.g., the second lifting assembly 104) are arranged opposite to each other. Alternatively, in a lifting assembly group located on the same side of the product to be moved, the two first columns are located inside the two second columns. In other alternative embodiments, the two first columns may also be located outside the two second columns.

[0068] In one implementation, please refer to Figure 2 and Figure 3 The transmission-type lifting device also includes a drive cylinder 18, which connects to and drives the first column 11 in the first lifting assembly (e.g., the first lifting assembly 103) and the first column 11 in the corresponding second lifting assembly (e.g., the second lifting assembly 104). In one embodiment, the two first columns are indirectly connected to the drive cylinder 18 via a connector 181.

[0069] In one implementation, such as Figure 2 and Figure 3 As shown, the transmission type lifting device 1 also includes a side guard strip 171, which is provided on the first column 11 and / or the second column 12, or it can be understood that the side guard strip 171 is provided on the first column 11 or the second column 12, or both of them are provided with side guard strip 171.

[0070] The edge strip 171 extends in the same direction as the first column 11 (or can be understood as the height direction). When the product to be moved (e.g., sunroof glass 2) is placed on the first bracket 111 or the second bracket 121, the edge strip 171 contacts the edge of the product to be moved (e.g., sunroof glass 2).

[0071] In this embodiment of the invention, by providing edge strips 171 on the first column 11 and / or the second column 12, it is helpful to quickly position the product to be moved (e.g., sunroof glass 2) on the first bracket 111 or the second bracket 121.

[0072] In one implementation, such as Figure 2 and Figure 3 As shown, the edge strip 171 is disposed on the second column 12. The transmission-type lifting device 1 also includes an adjusting member 172, which is connected to the edge strip 171 and the second column 12. The adjusting member 172 is used to adjust the distance between the side walls of the edge strip 171 and the second column 12 to accommodate products of different sizes to be moved (e.g., sunroof glass 2). The adjusting member 172 may be, for example, a screw, which adjusts the distance between the side walls of the edge strip 171 and the second column 12 by tightening or loosening it. In other alternative embodiments, the adjusting member 172 may also be other pluggable connectors, etc.

[0073] In one implementation, such as Figure 4 and Figure 5 As shown, Figure 4 This is a three-dimensional structural diagram of the transfer lifting device according to an embodiment of the present invention, showing the product to be moved placed on the first bracket. Figure 5 for Figure 4A partially enlarged structural diagram of region A. A slide rail 123 is provided on the side wall of the second column 12, and sliders 113 are provided on the corresponding side walls of the first column 11 and the second column 12. The first column 11 slides along the slide rail 123 on the side wall of the second column 12 via the sliders 113. In one embodiment, as... Figure 5 As shown, the slide rail 123 is strip-shaped and the slider 113 is roller-shaped. In other alternative embodiments, the slide rail 123 and the slider 113 can also be other matching shapes, which are not limited in this invention.

[0074] In one implementation, such as Figure 4 As shown, the transfer-type lifting device 1 also includes a base 191 and a sliding plate 192. The sliding plate 192 is slidably connected to the base 191 and can slide along the surface of the base 191 in a direction closer to or away from the product to be moved (e.g., the sunroof glass 2). At least one lifting component is mounted on the sliding plate 192. In this embodiment of the invention, the transfer-type lifting device can adjust the relative positions of each lifting component by sliding the sliding plate 192 on the base 191, thereby adapting to products of different sizes to be moved. In one embodiment, the lower surface of the sliding plate 192 is provided with a slider, and the surface of the base 191 is provided with a base slide rail 193, which are matched to achieve relative sliding.

[0075] In one embodiment, along the sliding direction of the sliding plate 192, the base 191 is provided with a plurality of positioning holes 1910. The sliding plate 192 passes through one of the positioning holes 1910 via a fixing member 1911, so that the lifting assembly is fixed in position on the base 191 to adapt to the product to be moved. The fixing member 1911 may be, for example, a screw, a pin, etc.

[0076] Taking a car sunroof glass as an example, the following is an illustration of the working process of a transfer-type lifting device. Please refer to [link / reference]. Figure 6 and Figure 7 and combined Figure 3 Understanding. Among them, Figure 6 This is a side view of the conveyor-type lifting device in an embodiment of the present invention. Figure 7 This is a side view of the transmission-type lifting device in an embodiment of the present invention.

[0077] Figure 6 In the process, the first bracket 111 is located in the first supporting position, and the second bracket 121 is located in the avoidance position. Specifically, during the lifting process, the sunroof glass 2 is placed on the first bracket 111, and the first column 11 is lifted by the drive cylinder 18. During the lifting process, the edge of the sunroof glass 2 contacts the second bracket 121, and as the height increases, the second bracket 121 is pushed by the sunroof glass to a position similar to the first support position. Figure 6 The indicated avoidance position continues until each skylight glass 2 is raised to the designated position.

[0078] Figure 7 In the middle, the first bracket 111 is in the non-support position and the second bracket 121 is in the second support position. During the descent, the drive cylinder 18 drives the first column 11 to descend. When the edge of the sunroof glass 2 comes into contact with the second bracket 121 and is finally completely supported by the second bracket 121, the descent stops. At this time, the first bracket 111 rotates to the non-support position under the action of gravity.

[0079] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
