Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning technology, and in particular to a workpiece loading and positioning device and loading equipment. Background Technology

[0002] In automated assembly, welding, and testing production lines, whether workpieces can enter the processing and assembly stations with the correct posture, sufficient precision, and stable reliability directly determines the production line's cycle time, yield, and overall cost.

[0003] For example, patent CN110304447B discloses a solar panel loading and positioning device. The solar panel is placed on a receiving plate via a conveying device. A positioning cylinder retracts, pushing the end clamping block inwards. The sliding bar, under the restoring force of a spring, moves inwards, positioning the workpiece on the receiving plate. After positioning, the positioning cylinder extends, pushing the end clamping block outwards. The inclined surface of the drive block drives the transmission bar, pushing the sliding bar outwards to release the workpiece, allowing it to be moved away for the next positioning cycle. However, this process requires the workpiece to be transported to the receiving plate via a conveying device for loading, followed by positioning on the receiving plate. This operation is cumbersome and inefficient. Utility Model Content

[0004] In view of this, the present invention proposes a workpiece loading and positioning device and loading equipment, which can solve the problem that the workpiece needs to be transported to the receiving plate by a conveying device for loading and then positioned on the receiving plate, which leads to cumbersome operation and low work efficiency.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a workpiece loading and positioning device for use in conjunction with a feeding device, comprising: A positioning frame has a feeding trough and a feeding opening. The feeding trough extends along a first direction, and the feeding opening is connected to the feeding trough but in a different direction. The feeding opening is connected to the discharge end of the feeding device. The positioning mechanism includes a positioning component movably disposed on the positioning frame along the opening direction of the feeding trough, and the positioning component is movably disposed within the feeding trough. The positioning component includes a first limiting block and a second limiting block spaced apart along the first direction. The first limiting block and the second limiting block are respectively used to limit the workpiece on both sides of the first direction.

[0006] Based on the above technical solutions, preferably, the positioning mechanism is disposed at the bottom of the positioning frame, and the positioning mechanism further includes a positioning drive component disposed on the positioning frame, the positioning drive component being used to drive the positioning component to rise and fall.

[0007] More preferably, the feeding trough is provided with a first positioning guide port and a second positioning guide port, the first positioning guide port is used to cooperate with the first limiting block, and the second positioning guide port is used to cooperate with the second limiting block.

[0008] Based on the above technical solutions, preferably, the first limiting block has a first limiting side, which is used to contact and cooperate with one side of the workpiece in the first direction. The second limiting block has a second limiting side surface and a bottom surface connected to each other. The second limiting side surface is used to contact and cooperate with the other side of the workpiece in the first direction, and the bottom surface is used to contact and cooperate with the bottom surface of the workpiece.

[0009] Based on the above technical solutions, preferably, the feeding trough has a first feeding wall and a second feeding wall spaced apart along a second direction, the second direction being perpendicular to the first direction, the feeding opening being opened on the second feeding wall, and a positioning detection element being provided on the first feeding wall.

[0010] Based on the above technical solutions, preferably, the top of the feeding trough is covered with a cover plate.

[0011] Based on the above technical solutions, preferably, it also includes a conveying mechanism, which includes a pushing component and a conveying drive component. The pushing component is disposed in the feeding trough, and the conveying drive component is disposed on the positioning frame and is used to drive the pushing component to move along the first direction in the feeding trough; the feeding opening is connected to the middle position of the feeding trough.

[0012] This utility model also provides a feeding device, including a feeding device and the workpiece feeding and positioning device described above. The feeding device includes a feeder and a conveying guide rail. One end of the conveying guide rail is connected to the feeder, and the other end of the conveying guide rail is connected to the feeding opening.

[0013] Based on the above technical solutions, preferably, the material conveying guide rail is embedded in the feeding opening.

[0014] More preferably, the end of the material conveying guide rail is flush with the end of the feeding trough.

[0015] The workpiece loading and positioning device and loading equipment of this utility model have the following advantages over the prior art: (1) By connecting the discharge end of the feeding device with the loading opening, the workpiece can be stably conveyed to the loading opening and enter the loading trough through the loading opening, thus completing the automatic loading. By moving the positioning component, the first limit block and the second limit block limit the opposite sides of the workpiece respectively, and the other two sides of the workpiece are limited by the loading trough and the discharge end of the feeding device respectively, thereby realizing the automatic positioning of the workpiece after loading, which facilitates the subsequent operation of the workpiece. This device does not require the workpiece to be transported and loaded by the handling device, which is convenient to operate, greatly improves the work efficiency, and reduces the time cost; (2) By setting up the positioning detection component, when the workpiece is pushed to be aligned with the positioning detection component, the positioning detection component immediately sends out a positioning signal; since the positioning detection component is set on the side opposite to the workpiece entry direction, the workpiece is directly detected when it reaches the predetermined position, thus reducing intermediate transmission error and improving the real-time performance and reliability of positioning judgment.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 6 As shown, this utility model provides a workpiece loading and positioning device for use in conjunction with a feeding device. The workpiece loading and positioning device includes a positioning frame 1 and a positioning mechanism 2. The positioning frame 1 has a loading groove 11 and a loading opening 12. The loading groove 11 extends along a first direction, and the loading opening 12 is connected to the loading groove 11 but has a different opening direction. The loading opening 12 is connected to the discharge end of the feeding device. The positioning mechanism 2 includes a positioning component 21 movably disposed on the positioning frame 1 along the opening direction of the loading groove 11 and is movably disposed within the loading groove 11. The positioning component 21 includes a first limiting block 211 and a second limiting block 212 spaced apart along the first direction. The first limiting block 211 and the second limiting block 212 are respectively used to limit the workpiece 100 on both sides of the first direction.

[0021] The feeding device is used to stably feed workpiece 100. By connecting the discharge end of the feeding device to the feeding opening 12, the workpiece 100 can be stably conveyed to the feeding opening 12 and enter the feeding trough 11 through the feeding opening 12, thus completing automatic feeding. The positioning component 21 moves, causing the first limiting block 211 and the second limiting block 212 to respectively limit the opposite sides of the workpiece 100. The other two sides of the workpiece 100 are respectively limited by the feeding trough 11 and the discharge end of the feeding device, thereby achieving automatic positioning of the workpiece 100 after feeding, facilitating subsequent operations. This device eliminates the need for a handling device to transport and feed the workpiece 100, making operation convenient, greatly improving work efficiency, and reducing time costs.

[0022] In some embodiments, the opening of the feeding trough 11 is arranged facing upwards, and the positioning mechanism 2 can be arranged on the top of the positioning frame 1. In order to avoid interference between the positioning mechanism 2 and the workpiece 100 feeding process, the positioning mechanism 2 in this embodiment is arranged at the bottom of the positioning frame 1.

[0023] The positioning mechanism 2 further includes a positioning drive component 22 disposed on the positioning frame 1. The positioning drive component 22 is used to drive the positioning component 21 to rise and fall. By driving the positioning component 21 to rise and fall, the positioning component 21 is moved into the loading trough 11 to position the workpiece 100; or it is moved out of the loading trough 11 to ensure stable loading of the workpiece 100. The positioning drive component 22 can be a cylinder, hydraulic cylinder, or oil cylinder. In this embodiment, the positioning drive component 22 is a positioning cylinder. The piston rod of the positioning cylinder is connected to the positioning component 21, so that the positioning component 21 is raised and lowered by the extension and retraction of the piston rod.

[0024] In some embodiments, the loading opening 12 is connected to the loading trough 11, but they are opened in different directions. The loading trough 11 is opened in the height direction, meaning that the loading opening 12 is opened in any direction that forms an angle with the height direction. In this embodiment, the loading trough 11 has a first loading wall 111 and a second loading wall 112 spaced apart along a second direction, which is perpendicular to the first direction. The loading opening 12 is opened on the second loading wall 112, and the angle between the opening direction of the loading opening 12 and the height direction is 90 degrees. That is, the opening direction of the loading opening 12 is perpendicular to the opening direction of the loading trough 11, which facilitates the subsequent stable positioning of the workpiece 100 in the loading trough 11.

[0025] In some embodiments, a first positioning guide port 13 and a second positioning guide port 14 are provided through the feeding trough 11. The first positioning guide port 13 is used to cooperate with the first limiting block 211, and the second positioning guide port 14 is used to cooperate with the second limiting block 212. The first positioning guide port 13 and the second positioning guide port 14 provide positioning and guidance for the movement of the first limiting block 211 and the second limiting block 212, ensuring the positional stability of the first limiting block 211 and the second limiting block 212 during the lifting process, ensuring the positioning effect of the workpiece 100, and ensuring the positioning consistency of different workpieces 100.

[0026] Optionally, the first limiting block 211 has a first limiting side surface 2111, which is used to contact and cooperate with one side of the workpiece 100 in the first direction; the second limiting block 212 has a connected second limiting side surface 2121 and a bottom surface 2122, which is used to contact and cooperate with the other side of the workpiece 100 in the first direction, and the bottom surface 2122 is used to contact and cooperate with the bottom surface of the workpiece 100. The first limiting block 211 and the second limiting block 212 respectively restrict the workpiece 100 on opposite sides in the first direction, and the bottom surface 2122 provides vertical support for the workpiece 100. Furthermore, the workpiece 100 is limited on both sides in the second direction by the feeding trough 11 and the discharge end of the feeding device, thereby positioning the workpiece 100 in multiple degrees of freedom, ensuring the reliability of the workpiece 100's positioning, and thus guaranteeing the consistency of the reference for subsequent processing or inspection.

[0027] Optionally, the top of the feeding trough 11 is covered with a cover plate 5. The cover plate 5 can limit the top of the workpiece 100, preventing the workpiece 100 from detaching from the feeding trough 11 through the top opening during the positioning process. Of course, to ensure stable feeding and unloading of the workpiece 100, the distance between the cover plate 5 and the bottom of the feeding trough 11 is greater than the height of the workpiece 100.

[0028] In some embodiments, a positioning detection element 3 is provided on the first feeding wall 111, and a feeding opening 12 is opened on the second feeding wall 112, so that the workpiece 100 enters the feeding trough 11 from the side. The positioning detection element 3 can be a photoelectric sensor or a proximity sensor. When the workpiece 100 is pushed to align with the positioning detection element 3, the positioning detection element 3 immediately sends a positioning signal. Since the positioning detection element 3 is located on the side opposite to the entry direction of the workpiece 100, the workpiece 100 is directly detected when it reaches the predetermined position, thus reducing intermediate transmission errors and improving the real-time performance and reliability of positioning judgment.

[0029] After detecting that workpiece 100 has arrived, the controller can stop the feeding device to prevent subsequent workpieces 100 from squeezing against the arrived workpiece 100. Of course, the controller can also simultaneously control the operation of the positioning drive component 22, driving the positioning component 21 to rise and position the workpiece 100, thus realizing automated positioning control after loading.

[0030] like Figures 1 to 6As shown, in some embodiments, the workpiece loading and positioning device further includes a conveying mechanism 4. The conveying mechanism 4 includes a pusher 41 and a conveying drive component 42. The pusher 41 is disposed in the loading trough 11, and the conveying drive component 42 is disposed on the positioning frame 1 and is used to drive the pusher 41 to move along the first direction within the loading trough 11. The loading opening 12 is connected to the middle position of the loading trough 11. When the workpiece 100 is loaded into the loading trough 11, it will first be located in the middle of the loading trough 11. The pusher 41 is located at one end of the loading trough 11. The movement of the pusher 41 can drive the workpiece 100 to move towards the other end of the loading trough 11, realizing the transfer operation of the workpiece 100 after positioning. Similarly, the conveying drive component 42 can adopt a structure such as a cylinder, hydraulic cylinder, or screw drive. In this embodiment, the conveying drive component 42 adopts a conveying cylinder.

[0031] In summary, this application provides a workpiece loading and positioning device. The feeding device is used to stably load the workpiece 100. By connecting the discharge end of the feeding device to the loading opening 12, the workpiece 100 can be stably conveyed to the loading opening 12 and enter the loading trough 11 through the loading opening 12, thereby completing automatic loading. By moving the positioning component 21, the first limiting block 211 and the second limiting block 212 respectively limit the opposite sides of the workpiece 100. The other two sides of the workpiece 100 are respectively limited by the loading trough 11 and the discharge end of the feeding device, thereby realizing automatic positioning of the workpiece 100 after loading, which facilitates subsequent operations of the workpiece 100. This device eliminates the need for a handling device to transport and load the workpiece 100, making operation convenient, greatly improving work efficiency, and reducing time costs.

[0032] like Figures 1 to 6 As shown, this utility model also provides a feeding device, including a feeding device and a workpiece feeding and positioning device as described above. The feeding device includes a feeder 6 and a conveying guide rail 7. One end of the conveying guide rail 7 is connected to the feeder 6, and the other end of the conveying guide rail 7 is connected to the feeding opening 12. The feeder 6 of the feeding device continuously discharges the workpiece 100 by vibration or rotation. The workpiece 100 then enters the conveying guide rail 7, which extends in a straight line. Its discharge end is connected to the feeding opening 12 of the workpiece feeding and positioning device, thereby ensuring that the workpiece 100 can enter the positioning device in a constant posture.

[0033] In some embodiments, the conveying guide rail 7 is embedded in the feeding opening 12, and the end of the conveying guide rail 7 is flush with the end of the feeding groove 11. After the workpiece 100 slides out from the conveying guide rail 7, it can directly enter the feeding groove 11, which avoids the workpiece 100 jumping or tilting at the connection point, and also avoids the workpiece 100 interfering with the conveying guide rail during subsequent conveying and other processes.

[0034] Of course, the material conveying guide 7 is embedded in the feeding opening 12 to ensure the stability of the material conveying guide 7 on the feeding opening 12 and to ensure the stable feeding of the workpiece 100. The material conveying guide 7 can also be overlapped on the feeding opening 12 to facilitate the installation and disassembly of the feeding device and the positioning device, and to facilitate maintenance and replacement.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
