Description

Technical Field

[0001] The present application relates to the technical field of automobile manufacturing, and in particular to a lifting device and a transmission system. Background Art

[0002] With the continuous development of the automobile industry and the advancement of science and technology, the shape of modern automobiles has become increasingly complex, with huge changes in shape and surface, which puts higher requirements on the production accuracy and quality of stamping parts. In the stamping production line, the robot is responsible for taking the stamping parts out of the press and placing them on the belt conveyor for subsequent processing.

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

[0004] At present, there is no effective solution specifically for this problem in the industry. Although traditional methods such as using cushioning materials or adjusting the robot placement strategy can alleviate the deformation problem to a certain extent, they cannot fundamentally solve the problem of falling deformation caused by height difference of stamping parts, which affects the production quality of stamping parts and the stability of their subsequent processing. Summary of the invention

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0047] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0048] like Figure 2 As shown, an embodiment of the present application provides a lifting device 10 , which includes a carrying mechanism 1 and a lifting mechanism 2 .

[0049] The lifting device 10 is suitable for a workpiece production line, and in particular, is suitable for a production line of automobile stamping parts 100. The embodiment of the present application is described by taking the workpiece being an automobile stamping part 100 as an example.

[0050] like Figure 2 As shown, the bearing mechanism 1 includes a base 11 and a bearing platform 12 located on the top of the base 11 , and the base 11 is used to support the bearing platform 12 .

[0051] Optionally, the carrying platform 12 has a carrying surface for carrying the stamping part 100 , and the carrying surface can be fixed or movable relative to the ground, so as to facilitate the transfer of the stamping part 100 to other locations.

[0052] The lifting mechanism 2 includes a support member 21, a driving assembly 22 and two mounting seats 23. The two mounting seats 23 are respectively arranged 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 driving assembly 22 is transmission-connected to the support member 21. The driving assembly 22 is used to drive the support member 21 to rotate relative to the supporting platform 12, so that the second side of the support member 21 is lifted or lowered, wherein the first side and the second side of the support member 21 are arranged relatively to each other.

[0053] Specifically, the first side of the support member 21 corresponds to a side of the stamping member 100 with a lower height, and the second side of the support member 21 corresponds to a side of the stamping member 100 with a higher height.

[0054] If the high and low sides of the stamping part 100 are arranged along the length direction of the base 11, the first side and the second side of the support part 21 are also arranged along the length direction of the base 11; if the high and low sides of the stamping part 100 are arranged along the width direction of the base 11, the first side and the second side of the support part 21 are also arranged along the width direction of the base 11. Figure 3 or Figure 4 The horizontal direction of the base 11 is Figure 3 , Figure 4 or Figure 7 The vertical direction of the base 11 is Figure 7 Horizontal direction in .

[0055] For example, Figure 7 As shown, two mounting seats 23 are respectively arranged on both sides of the width direction of the base 11. The support member 21 is plate-shaped, and the first side and the second side of the support member 21 are two opposite sides of the support member 21 in the length direction of the base 11.

[0056] The support member 21 is used to compensate for the height difference between the front and rear sides of the stamping member 100, for example Figure 4 As shown, the support member 21 can be used to support the rear side (i.e. Figure 4 on the left side of the image).

[0057] Exemplarily, the working process of the lifting device 10 is as follows:

[0058] (1) After the stamping part 100 is formed by a production device (such as a press machine), a handling device (such as a robot) moves the stamping part 100 to the top of the carrying 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 of the stamping part 100 is higher than the front side.

[0059] (2) The driving assembly 22 drives the second side of the support member 21 to be lifted to a proper position, and the support member 21 supports the rear side of the stamping member 100;

[0060] (3) The handling device lowers the stamping part 100, and the front side of the stamping part 100 contacts the bearing surface of the bearing platform 12. At this time, the support member 21 remains stationary to ensure that the rear side of the stamping part 100 will not fall due to the height difference;

[0061] (4) After the handling device releases the stamping part 100, the driving assembly 22 drives the second side of the supporting member 21 to descend;

[0062] (5) The second side of the support member 21 descends to the initial position. At this time, the stamping part 100 is safely placed on the carrying platform 12.

[0063] It can be seen that the lifting device 10 improves the stability and reliability of the stamping part 100 during the picking and placing process, and can better meet the automotive industry's high-precision and high-quality production requirements for the stamping part 100. The operation of the lifting device 10 is more intelligent and automated, reducing the risks of manual intervention and misoperation, and improving production efficiency and product quality.

[0064] The lifting device 10 provided in the embodiment of the present application has a first side of the support member 21 that is rotatably mounted on two mounting seats 23, and the driving component 22 is transmission-connected to the support member 21. Therefore, driven by the driving component 22, the second side of the support member 21 can be lifted up or down. Therefore, in the process of placing workpieces such as the stamping part 100 on the supporting platform 12, the support member 21 is used to compensate for the height difference of the workpiece, so that the workpiece can be stably placed on the supporting platform 12 and the impact force during the placement of the workpiece can be absorbed to prevent the workpiece from falling and deforming due to the height difference, which is beneficial to ensuring the dimensional accuracy and appearance quality of the workpiece.

[0065] In a specific embodiment, the carrying platform 12 includes a belt conveyor assembly 121, and the carrying surface of the belt conveyor assembly 121 can be extended along the extension direction of the belt conveyor assembly 121 (ie Figure 3 or Figure 4 horizontal direction) movement.

[0066] In this embodiment, the bearing surface of the belt conveyor assembly 121 can move relative to the ground. After the stamping part 100 is safely placed on the bearing surface, the belt conveyor assembly 121 can transport the stamping part 100 to the other end, which is convenient for subsequent processing of the stamping part 100, reduces the step of manpower transportation of the stamping part 100, and is conducive to further improving production efficiency.

[0067] Exemplarily, the second side of the support member 21 is closer to the conveying direction of the belt conveyor assembly 121 (i.e. Figure 3 or Figure 4 In the direction from left to right in the middle (from left to right in the middle), so as to support the rear side of the stamping part 100.

[0068] In a further embodiment, driven by the driving assembly 22 , the support member 21 switches between a closed state and a lifting state.

[0069] like Figure 3 As shown, in the folded state, the support member 21 is parallel to the bearing surface of the belt transmission assembly 121 .

[0070] like Figure 4 As shown, in the lifting state, the support member 21 is inclined to the bearing surface of the belt transmission assembly 121 , and the second side of the support member 21 is higher than the first side of the support member 21 .

[0071] When the support member 21 does not support the stamping member 100 , the support member 21 is in a closed state, and the support member 21 is parallel to the bearing surface of the belt transmission assembly 121 , thereby reducing the space occupied by the support member 21 and avoiding potential safety hazards.

[0072] When the support member 21 needs to support the stamping member 100, the support member 21 switches to the lifting state to timely support and buffer the stamping member 100. The angle between the support member 21 and the bearing surface can be set according to actual needs, and this application does not make specific restrictions.

[0073] Exemplarily, the drive assembly 22 is communicatively connected to a control module (eg, a programmable logic controller, etc.) of a production device and / or a handling device so as to automatically and intelligently control the support member 21 to switch between a closed state and a lifting state.

[0074] In a specific embodiment, the driving assembly 22 includes a linear driving member 221 , which is disposed on the mounting seat 23 , and an output shaft of the linear driving member 221 is rotatably connected to the supporting member 21 .

[0075] The linear drive member 221 can be a drive member that can move in a straight line, such as a cylinder, an electric push rod, a ball screw mechanism, a linear motor, etc. Driven by the linear drive member 221, the height of the second side of the support member 21 can change to achieve lifting or lowering operations.

[0076] For example, the linear drive member 221 is a cylinder, and the drive assembly 22 further includes an air pipe 222, an air line connector 223, a reversing member 224 and a controllable switching device 225. Figure 3 and Figure 4 As shown, the linear drive member 221 is installed on the mounting seat 23, the air circuit connector 223, the reversing member 224 and the controllable switching device 225 are installed on the base 11, one end of the air pipe 222 is connected to the linear drive member 221, and the other end is connected to the reversing member 224, the reversing member 224 is connected to the air circuit connector 223, and the air circuit connector 223 is used to connect to the air source so that the air source provides compressed air as power for the linear drive member 221.

[0077] Specifically, 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 member 221, and the second air pipe 222 is connected to the lower end of the linear drive member 221. When the first air pipe 222 is ventilated, compressed air enters the upper end of the linear drive member 221, and the piston of the linear drive member 221 is pushed to the lower end, thereby driving the output shaft to retract downward; when the second air pipe 222 is ventilated, compressed air enters the lower end of the linear drive member 221, and the piston of the linear drive member 221 is pushed to the upper end, thereby driving the output shaft to extend upward.

[0078] The controllable switching device 225 is connected to the control module of the production device and / or the handling device in communication, and the controllable switching device 225 is connected to the switching member 224, and can change the flow direction of the compressed gas in the switching member 224. After receiving the electrical signal sent by 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 control switching member 224, so that the first air pipe 222 or the second air pipe 222 is ventilated, and the output shaft of the linear drive member 221 is extended or retracted.

[0079] like Figure 3 As shown, the controllable switching device 225 is in the first position, the air inlet end of the second air pipe 222 is blocked by the controllable switching device 225, and only the first air pipe 222 passes compressed gas. At this time, the compressed air enters the upper end of the linear drive member 221, and the piston of the linear drive member 221 will be pushed to the lower end, thereby driving the output shaft to retract downward, so that the support member 21 is in a closed state.

[0080] like Figure 4 As shown, the controllable switching device 225 is in the second position, the air inlet end of the first air pipe 222 is blocked by the controllable switching device 225, and only the second air pipe 222 passes compressed gas. At this time, the compressed air enters the lower end of the linear drive member 221, and the piston of the linear drive member 221 will be pushed to the upper end, thereby driving the output shaft to extend upward, so that the support member 21 is in a lifting state.

[0081] Specifically, the output shaft of the linear drive member 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 member 221 to be rotatably connected with the support member 21, it is possible to avoid jamming of the support member 21 with the output shaft of the linear drive member 221 during rotation.

[0082] In a further embodiment, Figure 5 As shown, the lifting mechanism 2 further includes a first transmission member 3 and a second transmission member 4 .

[0083] like Figure 3 or Figure 4 As shown, a first rotating shaft 31 is disposed at one end of the first transmission member 3, and the first rotating shaft 31 is rotatably connected to the mounting seat 23. The second transmission member 4 is disposed on a side of the support member 21 close to the carrying platform 12, and the second transmission member 4 and the first rotating shaft 31 are spaced apart along the extension direction of the first transmission member 3. The second transmission member 4 is provided with a second rotating shaft 41, and the second rotating shaft 41 is connected to the output shaft of the linear drive member 221, and the second rotating shaft 41 can rotate relative to the support member 21 and can slide relative to the support member 21.

[0084] Specifically, the first rotating shaft 31 and the second rotating shaft 41 extend along the width direction of the base 11 . Driven by the driving assembly 22 , the supporting member 21 rotates around the central axis of the first rotating shaft 31 .

[0085] For example, Figure 3 As shown, the first transmission member 3 is rod-shaped and fixed to the side of the support member 21 close to the carrying platform 12, that is, the first transmission member 3 is located at 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.

[0086] In this embodiment, the first rotating shaft 31 and the second rotating shaft 41 are provided to realize the rotation connection between the support member 21 and the mounting seat 23 and the rotation connection between the support member 21 and the driving assembly 22. The second rotating shaft 41 can slide relative to the support member 21, ensuring that the support member 21 rotates smoothly and will not be stuck by the output shaft of the linear driving member 221.

[0087] Furthermore, if 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 close to the carrying platform 12. The third transmission member 5 is provided with a limiting groove 51, and the limiting groove 51 extends along the extension direction of the first transmission member 3. The second transmission member 4 can be movably installed in the limiting groove 51 and can move along the extension direction of the limiting groove 51.

[0088] like Figure 5 As shown, the third transmission member 5 is fixed to the bottom side of the support member 21, and 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, so that during the rotation of the support member 21, the relative sliding between the second transmission member 4 and the third transmission member 5 is utilized to ensure that the support member 21 can rotate smoothly around the central axis of the first rotating shaft 31, and avoid the support member 21 and the output shaft of the driving assembly 22 from being stuck.

[0089] In an optional embodiment, the limiting groove 51 is a rectangular groove opened in the third transmission member 5. The second transmission member 4 is abutted against the inner wall of the front end / rear end of the limiting groove 51 to limit the movement range of the second transmission member 4, which can prevent the second transmission member 4 from detaching from the limiting groove 51 and also prevent the second transmission member 4 from excessive movement, which would affect the support effect on the stamping part 100.

[0090] It can be understood that the front inner wall and the rear inner wall of the limiting groove 51 are two inner walls arranged opposite to each other along the extending direction of the first transmission member 3 .

[0091] In another optional embodiment, 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 on the mounting block 52, and the mounting block 52 and the two limiting blocks 53 enclose a limiting groove 51. The second transmission member 4 is provided with a stopper 42, the stopper 42 is located at least at one end of the second transmission member 4 in the extending direction of the limiting groove 51, and the stopper 42 is located outside the limiting groove 51 and is used to abut against the end surface of the limiting block 53.

[0092] like Figure 6 As shown, the two limit blocks 53 are fixed on the side of the mounting block 52 close to the supporting platform 12, that is, the bottom side of the mounting block 52, the bottom wall of the mounting block 52 constitutes the bottom wall of the limit groove 51, the side wall of each limit block 53 close to the other limit block 53 constitutes the side wall of the limit groove 51, and the second transmission member 4 is located between the two limit blocks 53.

[0093] Optionally, the side walls of the two limit blocks 53 are further provided with a boss 531, which is located at one end of the limit block 53 away from the mounting block 52, and the boss 531 protrudes outward relative to the limit block 53 where the boss 531 is located in the direction where the other limit block 53 is located, so that the two limit blocks 53 are in an "L" shape. The bottom surface of the second transmission member 4 abuts against the two bosses 531, so that the second transmission member 4 is limited by the two bosses 531 to prevent the second transmission member 4 from being separated from the limit groove 51.

[0094] Exemplarily, the stopper 42 is located at one end of the second transmission member 4. Figure 5 As shown, the stopper 42 is protruding relative to the side wall of the second transmission member 4. When the stopper 42 abuts against the end surface of the limit block 53, the second transmission member 4 reaches the limit position, preventing the second transmission member 4 from being disengaged from the limit groove 51 along the movement direction. Optionally, stoppers 42 are provided at both ends of the second transmission member 4, and the stoppers 42 at both ends define two limit positions of the second transmission member 4 in the movement direction.

[0095] In one embodiment, there are multiple groups of driving components 22 , and at least two groups of driving components 22 are respectively disposed on two opposite sides of the base 11 .

[0096] For example, Figure 7 As shown, the lifting device 10 includes two groups of driving assemblies 22 , and the two groups of driving assemblies 22 are arranged at intervals along the width direction of the base 11 .

[0097] By providing a plurality of driving components 22 , the driving effect on the support member 21 is improved, making the rotation of the support member 21 more stable and reliable.

[0098] Exemplarily, the assembly process of the lifting device 10 provided in the present application is as follows:

[0099] (1) Install the carrying platform 12 on the base 11 to ensure the stability of the carrying platform 12;

[0100] (2) Two mounting seats 23 are mounted on the base 11 to ensure that the mounting seats 23 are firm and reliable;

[0101] (3) Connecting the first rotating shaft 31 of the first transmission member 3 to the mounting seat 23, and adjusting the position and angle of the first rotating shaft 31 so that it can meet the rotation requirements of the support member 21;

[0102] (4) Fix the linear drive member 221 on the mounting seat 23, and connect the output shaft of the linear drive member 221 to the second rotating shaft 41 of the second transmission member 4;

[0103] (5) Install the third transmission member 5, place the second transmission member 4 into the limiting groove 51, and guide and limit the second transmission member 4 through the limiting groove 51 to ensure that the movement trajectory of the second transmission member 4 is stable and reliable;

[0104] (6) The support member 21 is installed on the top of the first transmission member 3, and the position and height of the support member 21 are adjusted so that it can play an effective buffering role when the stamping part 100 is placed.

[0105] The embodiment of the present application further provides a conveying system 20, and the conveying system 20 includes the lifting device 10 provided in any of the above embodiments.
