Abstract

This application provides a lifting device and a conveying system. The lifting device includes: a bearing mechanism, comprising a base and a bearing platform located on top of the base; the lifting mechanism includes a support member, a drive assembly, and two mounting seats, which are respectively disposed on opposite sides of the base. A first side of the support member is rotatably mounted on the two mounting seats. The drive assembly is drively connected to the support member and is used to drive the support member to rotate relative to the bearing platform, thereby raising or lowering a second side of the support member. The first and second sides of the support member are arranged opposite to each other.

Description

Technical Field

[0001] This application relates to the field of automobile manufacturing technology, and in particular to a method of using a lifting device. Background Technology

[0002] With the continuous development of the automotive industry and the advancement of science and technology, modern automobiles are becoming increasingly complex in design and exhibiting significant variations in shape, placing higher demands on the precision and quality of stamped parts production. In the stamping production line, robotic arms are responsible for removing stamped parts from the press and placing them on a conveyor belt for subsequent processing.

[0003] However, due to the significant height difference (nearly 300 mm) between the front and rear sides of the stamped part and the conveyor belt, when the front side of the stamped part contacts the conveyor belt, the rear side will suddenly fall onto the conveyor belt under the force of gravity. Figure 1 As shown, during the placement of the stamped part 100, the rear side of the stamped part 100 (i.e., Figure 1 The left side of the middle is higher than the front side (i.e., Figure 1 (Right side of the middle) After the front side of the stamped part 100 contacts the belt conveyor 200, the rear side of the stamped part 100 suddenly falls onto the belt conveyor 200 under the action of gravity. Since the stamped part 100 usually has the characteristics of thin thickness and complex shape, this falling process can easily cause the surface of the stamped part 100 to deform, affecting the dimensional accuracy and appearance quality of the product.

[0004] Currently, there is no effective solution in the industry specifically addressing this problem. While traditional methods such as using cushioning materials or adjusting the placement strategy of robotic arms can alleviate the deformation problem to some extent, they cannot fundamentally solve the problem of stamped parts deforming due to height differences, which affects the production quality of stamped parts and the stability of their subsequent processing. Summary of the Invention

[0005] In view of this, this application provides a method of using a lifting device to support and cushion the workpiece during placement, so as to prevent the workpiece from being damaged due to falling.

[0006] Specifically, the following technical solutions are included:

[0007] This application provides a method of using a lifting device, the lifting device comprising:

[0008] The support mechanism includes a base and a support platform located on top of the base;

[0009] The lifting mechanism includes a support member, a drive assembly, and two mounting seats. The two mounting seats are respectively disposed on opposite sides of the base. A first side of the support member is rotatably mounted on the two mounting seats. The drive assembly is connected to the support member for transmission. The drive assembly is used to drive the support member to rotate relative to the bearing platform, thereby raising or lowering the second side of the support member. The first and second sides of the support member are disposed opposite to each other.

[0010] The method of using the lifting device includes:

[0011] The conveying device moves the stamped part above the supporting platform;

[0012] The drive assembly drives the second side of the support member to rise to an appropriate position, and the support member supports the rear side of the stamping part;

[0013] The conveying device lowers the stamped part, and the front side of the stamped part contacts the bearing surface of the bearing platform. At this time, the support remains stationary to ensure that the rear side of the stamped part will not fall due to the height difference.

[0014] After the conveying device releases the stamped part, the drive assembly causes the second side of the support to descend;

[0015] The second side of the support member descends to its initial position.

[0016] In an optional embodiment, the carrying platform includes a belt conveyor assembly, the bearing surface of which is movable along the extension direction of the belt conveyor assembly.

[0017] In an optional embodiment, the support member switches between a closed state and a lifted state under the drive of the drive component.

[0018] In the closed state, the support member is parallel to the bearing surface of the belt conveyor assembly;

[0019] In the lifted state, the support member is inclined to the bearing surface of the belt conveyor assembly, and the second side of the support member is higher than the first side of the support member.

[0020] In an optional embodiment, the drive assembly includes a linear drive member disposed on the mounting base, the output shaft of the linear drive member being rotatably connected to the support member.

[0021] In an optional embodiment, the lifting mechanism further includes a first transmission member and a second transmission member;

[0022] One end of the first transmission component is provided with a first rotating shaft, and the first rotating shaft is rotatably connected to the mounting base;

[0023] The second transmission member is disposed on the side of the support member close to the bearing platform. The second transmission member and the first rotating shaft are spaced apart along the extension direction of the first transmission member. The second transmission member is provided with a second rotating shaft, which is connected to the output shaft of the linear drive member. The second rotating shaft can rotate relative to the support member and can slide relative to the support member.

[0024] In an optional embodiment, the lifting mechanism further includes a third transmission member located on the side of the support member near the bearing platform. The third transmission member is provided with a limiting groove that extends along the extending direction of the first transmission member. The second transmission member is movably installed in the limiting groove and is capable of moving along the extending direction of the limiting groove.

[0025] In an optional embodiment, the third transmission component includes a mounting block and two spaced-apart limiting blocks, the two limiting blocks being fixed to the mounting block, and the mounting block and the two limiting blocks forming the limiting groove.

[0026] The second transmission member is provided with a stop portion, which is located at at least one end of the second transmission member in the extending direction of the limiting groove. The stop portion is located outside the limiting groove and is used to abut against the end face of the limiting block.

[0027] In an optional embodiment, the drive components are in multiple sets, with at least two sets of drive components respectively disposed on opposite sides of the base.

[0028] The beneficial effects of the technical solution provided in this application embodiment include at least the following: Since the first side of the support member is rotatably mounted on two mounting seats and the drive assembly is connected to the support member in a transmission manner, the second side of the support member can be raised or lowered under the drive of the drive assembly. Thus, during the process of placing workpieces such as stamping parts onto the bearing platform, the support member is used to compensate for the height difference of the workpieces, and the workpieces are stably placed on the bearing platform. At the same time, the impact force when the workpieces are placed is absorbed, and the workpieces are prevented from falling and deforming due to the height difference. This is beneficial to ensuring the dimensional accuracy and appearance quality of the workpieces. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0051] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0052] This application provides a method for using the lifting device 10, such as... Figure 2 As shown, this application embodiment provides a lifting device 10, which includes a supporting mechanism 1 and a lifting mechanism 2.

[0053] The lifting device 10 is suitable for workpiece production lines, especially for production lines of stamped parts 100 for automobiles. This application embodiment uses stamped parts 100 for automobiles as an example for illustration.

[0054] like Figure 2 As shown, the support mechanism 1 includes a base 11 and a support platform 12 located on top of the base 11. The base 11 is used to support the support platform 12.

[0055] Optionally, the support platform 12 has a support surface for supporting the stamping part 100. The support surface can be fixed or moved relative to the ground to facilitate the transfer of the stamping part 100 to other locations.

[0056] The lifting mechanism 2 includes a support member 21, a drive assembly 22, and two mounting seats 23. The two mounting seats 23 are respectively disposed on opposite sides of the base 11. The first side of the support member 21 is rotatably mounted on the two mounting seats 23. The drive assembly 22 is connected to the support member 21 for transmission. The drive assembly 22 is used to drive the support member 21 to rotate relative to the bearing platform 12, thereby raising or lowering the second side of the support member 21. The first side and the second side of the support member 21 are disposed opposite to each other.

[0057] Specifically, the first side of the support member 21 corresponds to the side of the stamped part 100 with a lower height, and the second side of the support member 21 corresponds to the side of the stamped part 100 with a higher height.

[0058] If the high and low sides of the stamped part 100 are arranged along the length of the base 11, then the first and second sides of the support member 21 are also arranged along the length of the base 11; if the high and low sides of the stamped part 100 are arranged along the width of the base 11, then the first and second sides of the support member 21 are also arranged along the width of the base 11. Wherein, the length of the base 11 is... Figure 3 or Figure 4 The horizontal direction of the base 11 is [missing information], and the height direction of the base 11 is [missing information Figure 3 , Figure 4 or Figure 7 In the vertical direction, the width direction of the base 11 is... Figure 7 The horizontal direction in the middle.

[0059] For example, such as Figure 7 As shown, two mounting bases 23 are respectively disposed on both sides of the base 11 in the width direction. The support member 21 is plate-shaped, and the first side and the second side of the support member 21 are opposite sides of the support member 21 in the length direction of the base 11.

[0060] Support member 21 is used to compensate for the height difference between the front and rear sides of the stamped part 100, for example Figure 4 As shown, the support member 21 can be used to support the rear side of the stamped part 100 (i.e., Figure 4 (Left side of the middle).

[0061] For example, the operation of the lifting device 10 is as follows:

[0062] (1) After the stamping part 100 is formed by the production device (e.g., press), the handling device (e.g., robot) moves the stamping part 100 above the bearing platform 12. At this time, there is a height difference between the front and rear sides of the stamping part 100, and the rear side height of the stamping part 100 is higher than the front side height.

[0063] (2) The drive assembly 22 drives the second side of the support member 21 to rise to an appropriate position, and the support member 21 supports the rear side of the stamping part 100;

[0064] (3) The conveying device lowers the stamped part 100, and the front side of the stamped part 100 contacts the bearing surface of the bearing platform 12. At this time, the support 21 remains stationary to ensure that the rear side of the stamped part 100 will not fall due to the height difference.

[0065] (4) After the conveying device releases the stamping part 100, the drive assembly 22 drives the second side of the support part 21 to descend;

[0066] (5) The second side of the support member 21 descends to the initial position, at which point the stamping member 100 is safely placed on the bearing platform 12.

[0067] It can be seen that the lifting device 10 improves the stability and reliability of the stamped part 100 during the picking and placing process, and can better meet the automotive industry's production needs for high precision and high quality of the stamped part 100. Moreover, the operation of the lifting device 10 is more intelligent and automated, reducing the risk of manual intervention and misoperation, and improving production efficiency and product quality.

[0068] The lifting device 10 provided in this application embodiment has a first side of the support member 21 that is rotatably mounted on two mounting seats 23, and the drive assembly 22 is connected to the support member 21 in a transmission manner. Therefore, under the drive of the drive assembly 22, the second side of the support member 21 can be raised or lowered. Thus, during the process of placing workpieces such as the stamped part 100 onto the bearing platform 12, the support member 21 is used to compensate for the height difference of the workpieces, and the workpieces are stably placed on the bearing platform 12. At the same time, the impact force when the workpieces are placed is absorbed, and the workpieces are prevented from falling and deforming due to the height difference. This is beneficial to ensuring the dimensional accuracy and appearance quality of the workpieces.

[0069] In one specific embodiment, the support platform 12 includes a belt conveyor assembly 121, the bearing surface of which is capable of extending along the extension direction of the belt conveyor assembly 121 (i.e., Figure 3 or Figure 4 (Horizontal movement)

[0070] In this embodiment, the bearing surface of the belt conveyor assembly 121 can move relative to the ground. After the stamped part 100 is safely placed on the bearing surface, the belt conveyor assembly 121 can transport the stamped part 100 to the other end, which facilitates the subsequent processing of the stamped part 100, reduces the manual transportation of the stamped part 100, and helps to further improve production efficiency.

[0071] For example, the second side of the support 21 is closer to the conveying direction of the belt conveyor assembly 121 than the first side of the support 21 (i.e., Figure 3 or Figure 4 (From left to right) behind, so as to support the rear side of the stamping part 100.

[0072] In a further embodiment, the support member 21 switches between a closed state and a lifted state under the drive of the drive component 22.

[0073] like Figure 3 As shown, in the closed state, the support member 21 is parallel to the bearing surface of the belt conveyor assembly 121.

[0074] like Figure 4 As shown, in the lifting state, the support member 21 is inclined to the bearing surface of the belt conveyor assembly 121, and the second side of the support member 21 is higher than the first side of the support member 21.

[0075] When the support member 21 does not support the stamping part 100, the support member 21 is in a closed state, and the support member 21 is parallel to the bearing surface of the belt conveyor assembly 121, which reduces the space occupied by the support member 21 and avoids safety hazards.

[0076] When the support member 21 needs to support the stamped part 100, the support member 21 switches to the lifting state to provide timely support and buffer for the stamped part 100. The included angle between the support member 21 and the bearing surface can be set according to actual needs, and this application does not impose specific limitations.

[0077] For example, the drive component 22 is communicatively connected to the control module (e.g., a programmable logic controller) of the production device and / or the handling device to automatically and intelligently control the support 21 to switch between the closed state and the lifting state.

[0078] In one specific embodiment, the drive assembly 22 includes a linear drive 221, which is disposed on the mounting base 23, and the output shaft of the linear drive 221 is rotatably connected to the support member 21.

[0079] The linear drive component 221 can be a cylinder, electric push rod, ball screw mechanism, linear motor or other drive component that can move in a straight line. Under the drive of the linear drive component 221, the height of the second side of the support component 21 can change, so as to realize the operation of lifting or lowering.

[0080] For example, the linear drive 221 is a cylinder, and the drive assembly 22 also includes an air pipe 222, an air connector 223, a reversing component 224, and a controllable switching device 225, such as... Figure 3 and Figure 4 As shown, the linear drive 221 is mounted on the mounting base 23, and the air connector 223, the reversing component 224, and the controllable switching device 225 are mounted on the base 11. One end of the air pipe 222 is connected to the linear drive 221, and the other end is connected to the reversing component 224. The reversing component 224 is connected to the air connector 223. The air connector 223 is used to connect to an air source so that the air source provides compressed air as power to the linear drive 221.

[0081] Specifically, such as Figure 3 and Figure 4 As shown, there are two air pipes 222. The first air pipe 222 is connected to the upper end of the linear drive 221, and the second air pipe 222 is connected to the lower end of the linear drive 221. When the first air pipe 222 is ventilated, compressed air enters the upper end of the linear drive 221, and the piston of the linear drive 221 is pushed to the lower end, thereby causing the output shaft to retract downwards. When the second air pipe 222 is ventilated, compressed air enters the lower end of the linear drive 221, and the piston of the linear drive 221 is pushed to the upper end, thereby causing the output shaft to extend upwards.

[0082] The controllable switching device 225 is communicatively connected to the control module of the production device and / or the handling device. The controllable switching device 225 is connected to the reversing member 224 and can change the flow direction of the compressed gas in the reversing member 224. After receiving an electrical signal from the control module, the controllable switching device 225 generates movement according to the electrical signal, thereby changing the flow direction of the compressed air in the reversing member 224, thus allowing air to pass through the first air pipe 222 or the second air pipe 222, realizing the extension or retraction of the output shaft of the linear drive member 221.

[0083] like Figure 3 As shown, the controllable switching device 225 is in the first position, and the air inlet of the second air pipe 222 is blocked by the controllable switching device 225. Only the first air pipe 222 is supplied with compressed gas. At this time, the compressed air enters the upper end of the linear drive 221, and the piston of the linear drive 221 is pushed to the lower end, thereby driving the output shaft to retract downward, so that the support 21 is in the closed state.

[0084] like Figure 4 As shown, the controllable switching device 225 is in the second position. The air inlet of the first air pipe 222 is blocked by the controllable switching device 225, and only the second air pipe 222 is supplied with compressed gas. At this time, the compressed air enters the lower end of the linear drive 221, and the piston of the linear drive 221 is pushed to the upper end, thereby driving the output shaft to extend upward, so that the support 21 is in a lifting state.

[0085] Specifically, the output shaft of the linear drive 221 extends along the height direction of the base 11 and can move along the height direction of the base 11. By setting the output shaft of the linear drive 221 to be rotatably connected to the support 21, it is possible to avoid the support 21 from getting stuck with the output shaft of the linear drive 221 during rotation.

[0086] In a further embodiment, such as Figure 5 As shown, the lifting mechanism 2 also includes a first transmission component 3 and a second transmission component 4.

[0087] like Figure 3or Figure 4 As shown, one end of the first transmission member 3 is provided with a first rotating shaft 31, which is rotatably connected to the mounting base 23. The second transmission member 4 is provided on the side of the support member 21 near the bearing platform 12. The second transmission member 4 and the first rotating shaft 31 are spaced apart along the extending direction of the first transmission member 3. The second transmission member 4 is provided with a second rotating shaft 41, which is connected to the output shaft of the linear drive member 221. The second rotating shaft 41 can rotate relative to the support member 21 and can slide relative to the support member 21.

[0088] Specifically, the first rotating shaft 31 and the second rotating shaft 41 extend along the width direction of the base 11, and under the drive of the drive assembly 22, the support member 21 rotates around the central axis of the first rotating shaft 31.

[0089] For example, such as Figure 3 As shown, the first transmission member 3 is rod-shaped and fixed to the side of the support member 21 near the bearing platform 12, that is, the first transmission member 3 is located on the bottom side of the support member 21. The extension direction of the first transmission member 3 is from the first side to the second side of the support member 21, and the second transmission member 4 is located between the first side and the second side of the support member 21.

[0090] In this embodiment, by setting a first rotating shaft 31 and a second rotating shaft 41, a rotational connection between the support member 21 and the mounting base 23, as well as a rotational connection between the support member 21 and the drive assembly 22, is achieved. The second rotating shaft 41 can slide relative to the support member 21, ensuring that the support member 21 rotates smoothly and is not jammed by the output shaft of the linear drive member 221.

[0091] Furthermore, such as Figure 5 and Figure 6 As shown, the lifting mechanism 2 also includes a third transmission member 5, which is located on the side of the support member 21 near the bearing platform 12. The third transmission member 5 is provided with a limiting groove 51, which extends along the extending direction of the first transmission member 3. The second transmission member 4 is movably installed in the limiting groove 51 and can move along the extending direction of the limiting groove 51.

[0092] like Figure 5 As shown, the third transmission member 5 is fixed to the bottom side of the support member 21. Optionally, the third transmission member 5 is connected to the first transmission member 3. The second transmission member 4 is at least partially located in the limiting groove 51, and the second transmission member 4 is slidably connected to the third transmission member 5. Under the limitation of the limiting groove 51, the second transmission member 4 can move along the extension direction of the limiting groove 51. Thus, during the rotation of the support member 21, the relative sliding between the second transmission member 4 and the third transmission member 5 ensures that the support member 21 can rotate smoothly around the central axis of the first rotating shaft 31, avoiding jamming between the support member 21 and the output shaft of the drive assembly 22.

[0093] In an optional embodiment, the limiting groove 51 is a rectangular groove opened in the third transmission member 5. By the abutment of the second transmission member 4 against the inner wall of the front / rear end of the limiting groove 51, the movement range of the second transmission member 4 is limited. This can prevent the second transmission member 4 from disengaging from the limiting groove 51 and also avoid excessive movement of the second transmission member 4, which would affect the support effect on the stamping part 100.

[0094] It is understandable that the front inner wall and the rear inner wall of the limiting groove 51 are two inner walls that are arranged opposite each other along the extension direction of the first transmission member 3.

[0095] In another alternative embodiment, such as Figure 6 As shown, the third transmission member 5 includes a mounting block 52 and two spaced-apart limiting blocks 53. The two limiting blocks 53 are fixed to the mounting block 52, and the mounting block 52 and the two limiting blocks 53 together form a limiting groove 51. The second transmission member 4 is provided with a stop portion 42, which is located at least one end of the second transmission member 4 in the extending direction of the limiting groove 51. The stop portion 42 is located outside the limiting groove 51 and is used to abut against the end face of the limiting block 53.

[0096] like Figure 6 As shown, two limiting blocks 53 are fixed on the side of the mounting block 52 near the bearing platform 12, that is, the bottom side of the mounting block 52. The bottom wall of the mounting block 52 forms the bottom wall of the limiting groove 51. The side wall of each limiting block 53 near the other limiting block 53 forms the side wall of the limiting groove 51. The second transmission member 4 is located between the two limiting blocks 53.

[0097] Optionally, the sidewalls of the two limiting blocks 53 are further provided with protrusions 531. The protrusions 531 are located at the end of the limiting block 53 away from the mounting block 52, and the protrusions 531 protrude outward relative to the limiting block 53 in the direction of the other limiting block 53, so that the two limiting blocks 53 are in an "L" shape. The bottom surface of the second transmission member 4 abuts against the two protrusions 531, thereby using the two protrusions 531 to limit the second transmission member 4 and prevent the second transmission member 4 from disengaging from the limiting groove 51.

[0098] For example, the stop portion 42 is located at one end of the second transmission member 4, such as... Figure 5 As shown, the stop portion 42 protrudes outward relative to the side wall of the second transmission member 4. When the stop portion 42 abuts against the end face of the limiting block 53, the second transmission member 4 reaches its limit position, preventing the second transmission member 4 from disengaging from the limiting groove 51 along the movement direction. Optionally, stop portions 42 are provided at both ends of the second transmission member 4, thereby limiting the two limit positions of the second transmission member 4 in the movement direction.

[0099] In one embodiment, there are multiple sets of drive components 22, with at least two sets of drive components 22 respectively disposed on opposite sides of the base 11.

[0100] For example, such as Figure 7 As shown, the lifting device 10 includes two sets of drive components 22, which are spaced apart along the width direction of the base 11.

[0101] By setting multiple sets of drive components 22, the driving effect on the support member 21 is improved, making the rotation of the support member 21 more stable and reliable.

[0102] For example, the assembly process of the lifting device 10 provided in this application is as follows:

[0103] (1) Install the support platform 12 on the base 11 to ensure the stability of the support platform 12;

[0104] (2) The two mounting bases 23 are installed on the base 11 to ensure that the mounting bases 23 are firm and reliable;

[0105] (3) Connect the first shaft 31 of the first transmission component 3 to the mounting base 23, and adjust the position and angle of the first shaft 31 so that it can meet the rotation requirements of the support component 21;

[0106] (4) Fix the linear drive 221 on the mounting base 23 and connect the output shaft of the linear drive 221 to the second rotating shaft 41 of the second transmission component 4;

[0107] (5) Install the third transmission component 5 and place the second transmission component 4 into the limiting groove 51. The limiting groove 51 guides and limits the second transmission component 4 to ensure that the movement trajectory of the second transmission component 4 is stable and reliable.
