Description

Technical Field

[0001] This invention belongs to the field of automation technology, and in particular relates to a feeding and positioning device. Background Technology

[0002] The two components refer to the evaporator and condenser. Before bending, their positions are based on the robot's loading position. Therefore, the two components need to be positioned accurately before loading to ensure precise robot gripping. Traditionally, they are manually stacked onto a pallet, and the robot retrieves them from the stack. This production method has significant drawbacks. Manual stacking cannot guarantee the accurate positioning of the components, leading to deviations in the robot's loading position each time, resulting in substandard components. Furthermore, manual loading reduces work efficiency.

[0003] Therefore, there is an urgent need to design a feeding and positioning device to solve the problem mentioned above where the two feeding devices are not accurately positioned, thus reducing work efficiency. Summary of the Invention

[0004] To address the technical problem mentioned in the background art of inaccurate positioning of the two feeding devices due to manual feeding, which reduces work efficiency, a feeding and positioning device is provided to solve the above-mentioned problems.

[0005] To achieve the above objectives, the specific technical solution of the feeding and positioning device of the present invention is as follows:

[0006] A feeding and positioning device includes a bracket with a positioning plate on the bracket. One end of the positioning plate is hinged to the bracket. A workpiece is placed on the positioning plate, and the positioning plate is inclined relative to the bracket so that the workpiece moves to one end of the positioning plate in a first direction. The positioning plate is provided with a push-out component and a clamping component. The push-out component moves in a second direction to push the workpiece to the clamping component in the second direction. The clamping component clamps the workpiece in a third direction to position the workpiece on the positioning plate.

[0007] Furthermore, it also includes a drive assembly, which is mounted on the support and has its drive end connected to the positioning plate. The drive assembly drives the positioning plate to tilt relative to the support so as to move the workpiece to one end of the positioning plate along the first direction.

[0008] Furthermore, a baffle is also provided on the positioning plate. The baffle is located at the end where the positioning plate is hinged to the bracket, and the baffle blocks the workpiece.

[0009] Furthermore, the ejection assembly includes an ejection drive, which is disposed on the positioning plate and pushes the workpiece to move along the second direction to the clamping assembly.

[0010] Furthermore, the ejection assembly also includes an ejection plate disposed at the drive end of the ejection drive member, which is used to drive the workpiece to move along the second direction to the clamping assembly.

[0011] Furthermore, the clamping assembly includes a clamping frame, which is disposed on the positioning plate. A clamping drive is disposed on the clamping frame, and the clamping drive moves along a third direction to clamp and position the workpiece on the positioning plate.

[0012] Furthermore, the clamping assembly also includes a clamping plate, which is disposed at the driving end of the clamping drive member. The clamping plate abuts against the workpiece to position the workpiece on the positioning plate.

[0013] Furthermore, it also includes a support component, which is located at the end of the positioning plate away from the ejection component, and is used to support the workpiece or separate from the workpiece.

[0014] Furthermore, the support assembly includes a support plate, one end of which is hinged to the positioning plate. The support plate is used to support the workpiece or to separate it from the workpiece.

[0015] Furthermore, the support assembly also includes a support drive component, which is mounted on the bracket. The drive end of the support drive component is connected to the support plate, and the support drive component drives the support plate to support the workpiece or separate from the workpiece.

[0016] The feeding and positioning device of the present invention has the following advantages:

[0017] By installing a positioning plate on the support, with one end of the positioning plate hinged to the support, the workpiece is placed on the positioning plate, which is tilted relative to the support, so that the workpiece moves to one end of the positioning plate in a first direction. The positioning plate is equipped with an ejection component and a clamping component. The ejection component moves in a second direction to push the workpiece to the clamping component in the second direction. The clamping component clamps the workpiece in a third direction to position the workpiece on the positioning plate.

[0028] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0029] The following is a reference to the appendix. Figure 1 To be continued Figure 5 The feeding and positioning device of the present invention is described.

[0030] The two components refer to the evaporator and condenser. Before bending, their positions are based on the robot's loading position. Therefore, the components need to be accurately positioned before loading to ensure precise robot gripping. Traditionally, they are manually stacked onto a pallet, and the robot retrieves them from the stack. This production method has significant drawbacks. Manual stacking cannot guarantee the accurate positioning of the components, leading to deviations in the robot's loading position each time, resulting in substandard components. Furthermore, manual loading reduces work efficiency. Therefore, there is an urgent need to design a loading and positioning device to solve the problems mentioned above regarding inaccurate positioning and reduced efficiency caused by manual loading of the components.

[0031] like Figures 1 to 5 As shown, the feeding and positioning device of the present invention includes a support 1, a positioning plate 2 is provided on the support 1, one end of the positioning plate 2 is hinged to the support 1, the workpiece 8 is placed on the positioning plate 2, the positioning plate 2 is inclined relative to the support 1 so that the workpiece 8 moves along a first direction to one end of the positioning plate 2, the positioning plate 2 is provided with a push-out component 4 and a clamping component 5, the push-out component 4 moves along a second direction to push the workpiece 8 to move along the second direction to the clamping component 5, the clamping component 5 clamps the workpiece 8 along a third direction to position the workpiece 8 on the positioning plate 2. By providing a positioning plate 2 on the support 1, with one end of the positioning plate 2 hinged to the support 1, the workpiece 8 is placed on the positioning plate 2. The positioning plate 2 is inclined relative to the support 1, so that the workpiece 8 moves along a first direction to one end of the positioning plate 2. The positioning plate 2 is provided with an ejection component 4 and a clamping component 5. The ejection component 4 moves along a second direction to push the workpiece 8 along the second direction to the clamping component 5. The clamping component 5 clamps the workpiece 8 along a third direction to position the workpiece 8 on the positioning plate 2. This three-directional positioning and clamping of the workpiece 8 improves the accuracy and stability of the workpiece 8 clamping, and compared with manual clamping, reduces the labor intensity of workers and improves the efficiency of workpiece 8 clamping. In this embodiment, the workpiece 8 is a two-piece device. In this embodiment, the first direction is... Figure 1 The first direction is L1, the second direction is L2, and the third direction is L3.

[0032] like Figures 1 to 5As shown, after workpiece 8 is conveyed to the loading and positioning device by the conveyor line, the loading and positioning device limits workpiece 8 along the first direction, the second direction and the third direction, and clamps and fixes workpiece 8 after limiting it, so that workpiece 8 is limited and fixed in the same position of positioning plate 2 each time. After workpiece 8 is fixed, robot arm 9 moves to the positioning position of workpiece 8 and clamps workpiece 8 to the designated position for the next process.

[0033] Furthermore, such as Figures 1 to 5 As shown, the loading and positioning device of the present invention also includes a driving component 3, which is mounted on the support 1. The driving end of the driving component 3 is connected to the positioning plate 2. The driving component 3 drives the positioning plate 2 to tilt relative to the support 1, so as to move the workpiece 8 to one end of the positioning plate 2 along the first direction. In this embodiment, the driving component 3 is a driving cylinder. When the driving cylinder is in the initial position, the positioning plate 2 is arranged parallel to the support 1, so that the workpiece 8 can be transported from the conveyor line to the loading and positioning device. When the workpiece 8 is placed on the positioning plate 2 of the loading and positioning device, since one end of the positioning plate 2 is hinged to the support 1, the driving cylinder extends and drives the other end of the positioning plate 2 to move, so that the positioning plate 2 tilts at a certain angle relative to one end of the support 1. Due to the tilting effect of the positioning plate 2, the workpiece 8 on the positioning plate 2 slides down along the first direction to the end of the positioning plate 2 that is hinged to the support 1, thereby achieving the positioning of the workpiece 8 along the first direction. In this embodiment, to ensure smooth movement of the positioning plate 2 when it is tilted, two drive cylinders can be installed on the bracket 1. These two drive cylinders are spaced apart at the end of the positioning plate 2 furthest from the hinged end with the bracket 1. The two drive cylinders move synchronously, driving the positioning plate 2 to tilt relative to the bracket 1 at a certain angle, thereby positioning the workpiece 8 along the first direction. In this embodiment, the angle at which the drive cylinders drive the positioning plate 2 to tilt relative to the bracket 1 can be set according to actual conditions, as long as it can move the workpiece 8 along the first direction to the end of the positioning plate 2 hinged to the bracket 1.

[0034] Furthermore, such as Figures 1 to 5As shown, when the positioning plate 2 is tilted, when the workpiece 8 moves along the first direction to the end where the positioning plate 2 is hinged to the support 1, the workpiece 8 needs to be supported to ensure that it stops moving at this point. A baffle 7 is also provided on the positioning plate 2 at the hinged end, blocking the workpiece 8. During the tilting process of the positioning plate 2, as the workpiece 8 moves along the first direction to the hinged end, a buffer is provided on the baffle 7 to prevent damage during movement. The buffer is located on the side of the baffle 7 closest to the workpiece 8, cushioning the workpiece 8 and preventing it from colliding with the baffle 7 and damaging it. In this embodiment, the buffer is a rubber block, but it can also be any other relatively soft material that can provide cushioning and protection for the workpiece 8.

[0035] Furthermore, such as Figures 1 to 5 As shown, the ejection assembly 4 includes an ejection drive 41, which is mounted on the positioning plate 2. The ejection drive 41 pushes the workpiece 8 to move along the second direction to the clamping assembly 5. The ejection assembly 4 also includes an ejection plate 42, which is mounted on the drive end of the ejection drive 41. The ejection plate 42 is used to drive the workpiece 8 to move along the second direction to the clamping assembly 5. Specifically, the ejection drive 41 is a drive cylinder, which is mounted on the side of the positioning plate 2 away from the workpiece 8. To facilitate the movement of the ejection plate 42 along the second direction and to improve space utilization and reduce the overall size of the device, a groove along the second direction is provided on the positioning plate 2. The drive end of the ejection drive 41 passes through the groove and connects to the ejection plate 42. The ejection drive 41 moves along the second direction within the groove, thereby driving the ejection plate 42 to move along the second direction, pushing the workpiece 8, which is positioned along the first direction, to the clamping assembly 5 along the second direction. In this embodiment, to ensure smooth ejection of the ejector plate 42, two grooves are provided on the positioning plate 2, namely the first groove and the second groove. A connecting plate is connected to the ejection drive member 41, passing through the first groove and the second groove respectively and connecting to both ends of the ejector plate 42. This ensures that the ejector plate 42 moves smoothly during the process of pushing the workpiece 8 along the second direction, while also ensuring the effective ejection of the workpiece 8. In other embodiments, the ejection drive member 41 can also be a screw and nut structure to realize the movement of the ejector plate 42 along the second direction, or a gear and rack structure to realize the movement of the ejector plate 42, or any other structure, as long as it can realize the movement of the ejector plate 42 along the second direction, thereby realizing the movement of the workpiece 8 along the second direction and pushing the workpiece 8 to the clamping assembly 5.

[0036] Furthermore, such as Figures 1 to 5As shown, during the process of the ejector plate 42 pushing the workpiece 8 to move along the second direction to the clamping assembly 5, in order to ensure that the ejector plate 42 does not damage or scratch the workpiece 8 when pushing it, a buffer strip is provided on the ejector plate 42. The buffer strip is located on the side of the ejector plate 42 close to the workpiece 8. In this embodiment, the buffer strip is a rubber strip or other soft material, as long as it does not damage or scratch the workpiece 8 during the pushing process.

[0037] Furthermore, such as Figures 1 to 5 As shown, the clamping assembly 5 includes a clamping frame 51, which is mounted on the positioning plate 2. A clamping drive member 52 is mounted on the clamping frame 51. The clamping drive member 52 moves along a third direction to clamp and position the workpiece 8 on the positioning plate 2. Specifically, the clamping frame 51 includes a first support 511 and a second support 512, which are perpendicularly arranged. The first support 511 is located at the end of the positioning plate 2 near the baffle 7 and is perpendicular to the positioning plate 2. The second support 512 is perpendicular to the first support 511 and parallel to the positioning plate 2. The clamping drive member 52 is mounted on the second support 512, and its driving end moves along a direction perpendicular to the second support 512, i.e., along a third direction, to clamp and position the workpiece 8. In this embodiment, the clamping drive member 52 is a cylinder. The cylinder moves up and down relative to the positioning plate 2 to clamp the workpiece 8 that has moved to the clamping assembly 5. In other examples, the clamping drive 52 can also be a push rod or other mechanism, as long as it can achieve lifting and clamping and positioning of the workpiece 8. The clamping assembly 5 also includes a clamping plate 53, which is disposed at the driving end of the clamping drive 52. The clamping plate 53 is arranged parallel to the second bracket 512. The clamping drive 52 drives the clamping plate 53 to move, so that the clamping plate 53 moves away from or closer to the second bracket 512. The clamping drive 52 drives the clamping plate 53 to abut against the workpiece 8, so as to position the workpiece 8 on the positioning plate 2.

[0038] Furthermore, such as Figures 1 to 5As shown, to ensure smooth movement of the clamping plate 53 during the clamping of workpiece 8, a first guide structure 54 and a second guide structure 55 are provided on the second bracket 512. The clamping drive component 52 is disposed between the first guide structure 54 and the second guide structure 55. Through the guiding effect of the first guide structure 54 and the second guide structure 55, the clamping plate 53 can move smoothly relative to the second bracket 512, which also facilitates the clamping of workpiece 8. Specifically, the first guide structure 54 includes a first guide cylinder 541 and a first guide rod 542. The first guide cylinder 541 is disposed on the second bracket 512, one end of the first guide rod 542 is disposed on the clamping plate 53, and the other end of the first guide rod 542 passes through the second bracket 512 and slides inside the first guide cylinder 541. The second guide structure 55 includes a second guide cylinder 551 and a second guide rod 552. The second guide cylinder 551 is mounted on the second bracket 512, and one end of the second guide rod 552 is mounted on the clamping plate 53. The other end of the second guide rod 552 passes through the second bracket 512 and is slidably mounted inside the second guide cylinder 551. During the process of the clamping drive 52 driving the clamping plate 53 to move in a third direction, the first guide rod 542 slides inside the first guide cylinder 541, and the second guide rod 552 slides inside the second guide cylinder 551, ensuring that the clamping plate 53 moves smoothly during the movement in the third direction and ensuring high clamping efficiency.

[0039] Furthermore, such as Figures 1 to 5 As shown, during the clamping and positioning of the workpiece 8 along a third direction by the clamping plate 53, in order to ensure that the clamping plate 53 does not damage or scratch the workpiece 8 when clamping it, a buffer plate can be provided on the side of the clamping plate 53 near the workpiece 8. In this embodiment, the buffer plate is a rubber plate, but it can also be other relatively soft materials, as long as it can play a role in cushioning and protecting the workpiece 8.

[0040] Furthermore, such as Figures 1 to 5As shown, to further ensure the stability of the clamping plate 53 in clamping the workpiece 8, the clamping assembly 5 also includes an elastic element. The elastic element is disposed between the second bracket 512 and the clamping plate 53, ensuring that the clamping plate 53 can buffer the workpiece 8 during the clamping process, avoiding damage or scratches to the workpiece 8. In this embodiment, the elastic element includes a first elastic element and a second elastic element. Both the first elastic element and the second elastic element are disposed between the second bracket 512 and the clamping plate 53, playing a buffering role for the clamping plate 53. Specifically, in order to better fix the first elastic element and the second elastic element, the first elastic element is disposed on the first guide rod 542, with one end of the first elastic element abutting against the second bracket 512 and the other end abutting against the clamping plate 53. The second elastic element is disposed on the second guide rod 552, with one end of the second elastic element abutting against the second bracket 512 and the other end abutting against the clamping plate 53. By setting the first elastic element and the second elastic element, the clamping plate 53 is further elastically buffered, ensuring that the clamping plate 53 will not damage or scratch the workpiece 8 during the clamping process, and at the same time, it can also ensure that the clamping plate 53 can clamp the workpiece 8 tightly during the clamping process, avoiding the workpiece 8 from becoming loose. In this embodiment, both the first elastic element and the second elastic element are springs.

[0041] Furthermore, such as Figures 1 to 5 As shown, the feeding and positioning device of the present invention further includes a support component 6. The support component 6 is disposed at the end of the positioning plate 2 away from the ejection component 4. The support component 6 is used to support the workpiece 8 or to separate from the workpiece 8. The support component 6 is hinged to the positioning plate 2. Specifically, as shown... Figure 1 As shown, the support assembly 6 includes a support plate 61, one end of which is hinged to the positioning plate 2. The support plate 61 is used to support the workpiece 8 or to separate it from the workpiece 8. The support assembly 6 also includes a support drive member 62, which is mounted on the bracket 1. The drive end of the support drive member 62 is connected to the support plate, and the support drive member 62 drives the support plate 61 to support the workpiece 8 or to separate it from the workpiece 8. In this embodiment, the support drive member 62 is a drive cylinder. In other embodiments, the support drive member 62 can also be a push rod or other structures, as long as it can drive the support plate 61 to rotate relative to the positioning plate 2.

[0042] Furthermore, such as Figures 1 to 5As shown, when workpiece 8 is conveyed from the conveyor line to the loading and positioning device, the support drive 62 drives the support plate 61 to be parallel to the positioning plate 2, that is, the support plate 61 and the positioning plate 2 are on the same horizontal plane, which facilitates the workpiece 8 to enter the positioning plate 2 through the support plate 61. The conveyor line continues to convey workpiece 8 to the positioning plate 2. After the sensor on the positioning plate 2 senses that workpiece 8 has arrived on the positioning plate 2, the sensor sends a signal to the controller. The controller controls the drive assembly 3 to move. The drive assembly 3 drives the positioning plate 2 to rotate relative to the bracket 1 at a certain angle, so that the positioning plate 2 and the bracket 1 form an inclined angle. Since the positioning plate 2 is inclined relative to the bracket 1, the workpiece 8 on the positioning plate 2 slides along the first direction to the end where the positioning plate 2 and the bracket 1 are hinged. The drive assembly 3 drives the positioning plate 2 to tilt, thereby positioning the workpiece 8 along the first direction. Then, the push-out drive 41 drives the push-out plate 42 to move along the second direction, moving the workpiece 8 along the second direction to the clamping assembly 5. The push-out plate 42 is used to position the workpiece 8 along the second direction. In this embodiment, during the process of the ejector plate 42 ejecting the workpiece 8 and moving it along the second direction, when the ejector plate 42 pushes the workpiece 8 to the clamping assembly 5, part of the workpiece 8 is placed at the clamping assembly 5, and the other part is placed on the support plate 61. After the workpiece 8 is positioned along the second direction, the clamping drive member 52 drives the clamping plate 53 to clamp the workpiece 8 along the third direction, clamping and positioning the workpiece 8 on the positioning plate 2. After the workpiece 8 is positioned and clamped along the first direction, the second direction, and the third direction by the drive assembly 3, the ejector drive member 41, and the clamping drive member 52, all the workpieces 8 are positioned and clamped at the same position on the positioning plate 2 each time, which facilitates the subsequent gripping of the workpiece 8 by the robot arm 9, improves the accuracy of the workpiece 8 positioning, and also improves the efficiency and accuracy of the robot arm 9 in clamping the workpiece 8.

[0043] Furthermore, such as Figures 1 to 5As shown, when the ejector plate 42 pushes the workpiece 8 onto the clamping plate 53 along the second direction, part of the workpiece 8 is placed on the clamping plate 53 and the other part is placed on the support plate 61. After the clamping plate 53 clamps the workpiece 8 along the third direction, part of the workpiece 8 is fixed at the clamping plate 53 and part is placed on the support plate 61. When the robot arm 9 moves to the clamping plate 53 to clamp the workpiece 8, the presence of the support plate 61 will interfere with the mechanical clamping of the workpiece 8. Therefore, the support drive member 62 provided on the bracket 1 drives the support plate 61 to... When the positioning plate 2 is rotated by a certain angle, that is, the support plate 61 and the positioning plate 2 are not on the same plane, after the support plate 61 is rotated by a certain angle, the robot arm 9 can clamp the part of the workpiece 8 that contacts the support plate 61. After the robot arm 9 has clamped the workpiece 8, the clamping drive 52 drives the clamping plate 53 to release the workpiece 8, so that the robot arm 9 can clamp the workpiece 8 to the next station for subsequent processing. After the robot arm 9 has finished clamping the workpiece 8, the loading and positioning device has completed the clamping and positioning process of one workpiece 8 and begins the clamping and positioning of the next workpiece 8.

[0044] The working principle of the feeding and positioning device in this invention is as follows:

[0045] First, when workpiece 8 is conveyed from the conveyor line to the loading and positioning device, the support drive component 62 drives the support plate 61 to be parallel to the positioning plate 2, that is, the support plate 61 and the positioning plate 2 are on the same horizontal plane, which facilitates the workpiece 8 to enter the positioning plate 2 through the support plate 61. The conveyor line continues to convey workpiece 8 to the positioning plate 2. After the sensor on the positioning plate 2 senses that workpiece 8 has arrived on the positioning plate 2, the sensor sends a signal to the controller. The controller controls the drive component 3 to move. The drive component 3 drives the positioning plate 2 to rotate relative to the bracket 1 at a certain angle, so that the positioning plate 2 and the bracket 1 form an inclination. Due to the tilt of the positioning plate 2 relative to the bracket 1, the workpiece 8 on the positioning plate 2 slides along the first direction to the end where the positioning plate 2 is hinged to the bracket 1. The driving assembly 3 drives the positioning plate 2 to tilt, thereby positioning the workpiece 8 along the first direction. Next, the push-out driving member 41 drives the push-out plate 42 to move along the second direction, moving the workpiece 8 along the second direction to the clamping assembly 5. The push-out plate 42 then positions the workpiece 8 along the second direction. Finally, the clamping driving member 52 drives the clamping plate 53 to clamp the workpiece 8 along the third direction, positioning the workpiece 8 on the positioning plate 2. After the driving assembly 3, the push-out driving member 41, and the clamping driving member 52 position and clamp the workpiece 8 along the first, second, and third directions respectively, all workpieces 8 are positioned and clamped at the same position on the positioning plate 2 each time. This facilitates the subsequent gripping of the workpiece 8 by the robot arm 9, improving the accuracy of workpiece 8 positioning and also improving the efficiency and accuracy of the robot arm 9 in clamping the workpiece 8. When the robot arm 9 moves to the clamping plate 53 to clamp the workpiece 8, the presence of the support plate 61 will interfere with the robot arm 9's gripping of the workpiece 8. Therefore, the support drive 62 set on the bracket 1 drives the support plate 61 to rotate relative to the positioning plate 2 by a certain angle, that is, the support plate 61 and the positioning plate 2 are not on the same plane. After the support plate 61 rotates by a certain angle, the robot arm 9 can clamp the part of the workpiece 8 that contacts the support plate 61. After the robot arm 9 has clamped the workpiece 8, the clamping drive 52 drives the clamping plate 53 to release the workpiece 8, so that the robot arm 9 can clamp the workpiece 8 to the next station for subsequent processing. After the robot arm 9 has finished clamping the workpiece 8, the loading and positioning device has completed the clamping and positioning process of one workpiece 8 and begins the clamping and positioning of the next workpiece 8.
