Description

Technical Field

[0001] This application relates to the field of automatic feeding technology, and in particular to an automatic nut flipping and feeding device. Background Technology

[0002] Currently, after the nuts produced in batches pass inspection, they need to be picked up by a material handling mechanism, placed in a designated position, and finally tightened onto the equipment to be processed by a tightening gun.

[0003] The existing method usually requires workers to manually place the nut onto the tightening gun at a designated location and then use the tightening gun to fix the nut. This method of fixing the nut has a low level of automation, is time-consuming and labor-intensive, and needs to be improved. Utility Model Content

[0004] To facilitate the gripping of nuts by the tightening gun, this application provides an automatic nut flipping and feeding device.

[0005] This application provides an automatic nut flipping and feeding device, which adopts the following technical solution:

[0006] An automatic nut flipping and feeding device includes a drive conveying mechanism, a clamping and flipping unit for fixing the nut, and a detection mechanism for detecting the nut. The clamping and flipping unit is fixedly mounted on the drive conveying mechanism, and the detection mechanism is located at the end of the drive conveying mechanism in the conveying direction.

[0007] By adopting the above technical solution, and utilizing the setup of the drive conveying mechanism and the clamping and flipping unit, the drive conveying mechanism can automatically convey the nuts on the clamping and flipping unit. When the drive conveying mechanism reaches the end of the conveying direction, the detection mechanism can detect the position of the flipped nuts. At the same time, the clamping and flipping unit flips the nuts 90 degrees clockwise, making it easier for the mechanism with the tightening gun to transfer the nuts on the clamping and flipping unit to the next process. This greatly improves the automation level of the production line, reduces manual intervention, and increases production efficiency.

[0008] Preferably, the drive conveying mechanism includes a rodless cylinder and a conveying frame, the conveying frame being fixedly connected to the rodless cylinder, and the clamping and flipping unit being disposed on the conveying frame.

[0009] By adopting the above technical solution, the rodless cylinder is fixedly connected to the conveyor frame, which enables the conveyor frame to move synchronously with the piston of the rodless cylinder. This makes the conveying process of the nut more stable and reliable. At the same time, the rodless cylinder makes the overall structure more compact, which can reduce the overall area occupied and improve the space utilization rate.

[0010] Preferably, the clamping and flipping unit includes a rotary cylinder and a fixing seat for fixing the nut. The rotary cylinder's rotation shaft is fixedly connected to the fixing seat, and the side of the rotary cylinder opposite to the fixing seat is fixedly connected to the conveyor frame.

[0011] By adopting the above technical solution, the rotary cylinder and the fixed seat are configured so that the rotary cylinder can rotate the fixed seat, thereby flipping the nut to a position that is easy to hold with the tightening gun.

[0012] Preferably, the fixing base is provided with a positioning pin, and the positioning pin and the nut are engaged in a plug-in fit.

[0013] By adopting the above technical solution, the locating pin and the nut are connected in an interlocking manner, so that the nut can be initially fixed on the locating pin, which facilitates the transportation of the nut.

[0014] Preferably, the clamping and flipping unit includes a clamping cylinder, which is fixedly connected to the side of the fixed seat away from the rotating cylinder, and a clamping component for assisting in clamping the nut is fixedly connected to the side of the clamping cylinder away from the fixed seat.

[0015] By adopting the above technical solution and using the clamping device, the nut is further clamped and fixed, reducing the risk of the nut falling off during the flipping process.

[0016] Preferably, the clamping member is connected to the clamping cylinder by bolt thread.

[0017] By adopting the above technical solution, the clamping component and the clamping cylinder are connected by bolts and threads, which makes it convenient for workers to adjust or replace the clamping component.

[0018] Preferably, the drive conveying mechanism is provided with first sensors on both sides for detecting nuts.

[0019] By adopting the above technical solution and utilizing the setting of the first sensor, it is possible to detect whether there is a nut on the clamping and flipping unit. If there is a nut, the drive conveying mechanism will continue to move forward; if there is no nut, the drive conveying mechanism will return to the starting point.

[0020] Preferably, the detection mechanism includes a second support rod and a second sensor for detecting the nut. The second support rod is provided with a connecting post with a clamp, and the second sensor is provided on the connecting post. The connecting post is provided with an opening groove for clamping the connecting post and a locking member for locking the opening groove.

[0021] By adopting the above technical solution, and utilizing the opening slot and locking mechanism, the operator can control the closure of the opening slot by adjusting the tightness of the locking mechanism, thereby adjusting the position and height of the connecting column and connecting rod, and thus adjusting the height of the second sensor; at the same time, by utilizing the second sensor, the nut on the detection clamping and flipping unit can be detected before tightening the gun holding nut, reducing the error rate during the transfer process.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By utilizing the drive conveying mechanism and the clamping and flipping unit, the drive conveying mechanism can automatically convey the nuts on the clamping and flipping unit. When the drive conveying mechanism reaches the end of the conveying direction, the detection mechanism can detect the position of the flipped nuts. At the same time, the clamping and flipping unit flips the nuts 90 degrees clockwise, which makes it easier for the mechanism with the tightening gun to transfer the nuts on the clamping and flipping unit to the next process. This greatly improves the automation level of the production line, reduces manual intervention, and improves production efficiency.

[0024] 2. By using a rodless cylinder to fix the fixed frame, the fixed frame can move synchronously with the piston of the rodless cylinder, making the nut conveying process more stable and reliable. At the same time, the rodless cylinder makes the overall structure more compact, reducing the overall footprint and improving space utilization.

[0025] 3. By using a rotary cylinder and a fixed base, the rotary cylinder can rotate the fixed base, thereby flipping the nut to a position that is easy to hold with the tightening gun. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0031] This application discloses an automatic nut flipping and feeding device.

[0032] Reference Figure 1 An automatic nut flipping and feeding device includes a drive conveying mechanism 1, a clamping and flipping unit 2 for fixing the nut, and a detection mechanism 3 for detecting the nut. The clamping and flipping unit 2 is fixedly mounted on the drive conveying mechanism 1, and the detection mechanism 3 is located at the end of the drive conveying mechanism 1 in the conveying direction.

[0033] Reference Figure 1 By utilizing the drive conveying mechanism 1 and the clamping and flipping unit 2, the drive conveying mechanism 1 can automatically convey the nuts on the clamping and flipping unit 2. When the drive conveying mechanism 1 runs to the end of the conveying direction, the detection mechanism 3 can detect the position of the flipped nuts. At the same time, the clamping and flipping unit 2 flips the nuts 90 degrees clockwise, which makes it easier for the mechanism with the tightening gun to transfer the nuts on the clamping and flipping unit 2 to the next process. This greatly improves the automation level of the production line, reduces manual intervention, and improves production efficiency.

[0034] Reference Figure 2 The driving conveying mechanism 1 includes a rodless cylinder 11 and a conveying frame 12. The clamping and flipping unit 2 is disposed on the conveying frame 12. The conveying frame 12 is fixedly connected to the rodless cylinder 11. In this embodiment, the bottom of the conveying frame 12 is connected to the piston of the rodless cylinder 11 by bolts and threads, so that the fixed frame can move synchronously with the piston of the rodless cylinder 11, thereby making the conveying process of the nut more stable and reliable. At the same time, the setting of the rodless cylinder 11 makes the overall structure more compact, which can reduce the overall occupied area and improve the space utilization rate.

[0035] Reference Figure 1 The rodless cylinder 11 has detection components 13 vertically arranged on both sides. Since the two detection components 13 have the same structure and connection method, we will now describe one of the detection components 13 as an example. The detection component 13 includes a first support rod 131 and a first sensor 132 for detecting nuts. The first sensor 132 is installed on the first support rod 131. The first sensor 132 can detect whether there is a nut on the clamping and flipping unit 2. If there is a nut, the rodless cylinder 11 will drive the conveyor frame 12 to continue to move forward; if there is no nut, the rodless cylinder 11 will drive the conveyor frame 12 to return to the starting point.

[0036] Reference Figure 2The clamping and flipping unit 2 includes a rotary cylinder 21 and a fixing seat 22 for fixing the nut. The fixing seat 22 is L-shaped. The rotation shaft of the rotary cylinder 21 is fixedly connected to the fixing seat 22. The side of the rotary cylinder 21 away from the fixing seat 22 is fixedly connected to the conveyor frame 12. In this embodiment, the rotation shaft of the rotary cylinder 21 is connected to the fixing seat 22 by bolt thread, and the side of the rotary cylinder 21 away from the fixing seat 22 is connected to the conveyor frame 12 by bolt thread. By using the arrangement of the rotary cylinder 21 and the fixing seat 22, the rotary cylinder 21 can rotate the fixing seat 22, thereby flipping the nut to a position that is easy for the tightening gun to hold.

[0037] Reference Figure 2 The fixed base 22 is provided with a connector 221 and a positioning pin 222. The connector 221 is in the shape of a trapezoidal cylinder and is connected to the fixed base 22 by bolt thread. The positioning pin 222 is installed on the connector 221 and is used to form a plug-in engagement with the nut. When the fixed base 22 is located at the beginning of the conveying direction, the axis of the positioning pin 222 is set vertically, so that the nut can be initially fixed on the positioning pin 222, which facilitates the conveying of the nut.

[0038] Reference Figure 2 The clamping and flipping unit 2 also includes a clamping cylinder 23, which is fixedly connected to the side of the fixed base 22 away from the rotating cylinder 21. A clamping member 231 for assisting in clamping the nut is fixedly connected to the side of the clamping cylinder 23 away from the fixed base 22. There are two clamping members 231 arranged opposite to each other. The clamping members 231 further clamp and fix the nut, reducing the risk of the nut falling off during the flipping process. In this embodiment, the clamping cylinder 23 is connected to the fixed base 22 by bolt threads, and any clamping member 231 is connected to the piston of the clamping cylinder 23 by bolt threads, which makes it convenient for the staff to adjust or replace the clamping member 231.

[0039] Reference Figure 3 The detection mechanism 3 includes a second support rod 31 and a second sensor 3131 for detecting nuts. Connecting posts 311 are slidably provided at the top and bottom of the second support rod 31. Since the structures and connection methods of the two connecting posts 311 are the same, one connecting post 311 will be used as an example for explanation. Opening slots 3111 and locking members 3112 for locking the opening slots 3111 are provided at both ends of the length direction of the connecting post 311. In this embodiment, the locking member 3112 is a bolt. An insertion fit is formed between the opening slot 3111 at one end of the connecting post 311 and the connecting post 311, and the connecting post 311 is clamped and locked by the bolt. A connecting rod 312 is inserted into the opening slot 3111 at the other end of the connecting post 311, and the connecting rod 312 is clamped and locked by the bolt. The second sensor 3131 is mounted on the connecting rod 312.

[0040] Reference Figure 3 In actual operation, the operator can control the closure of the two opening slots 3111 by adjusting the tightness of the bolts, thereby adjusting the position and height of the connecting column 311 and the connecting rod 312, and thus adjusting the height of the second sensor 3131. At the same time, by using the setting of the second sensor 3131, the nut on the fixed seat 22 can be detected before the tightening gun is used to hold the nut, reducing the error rate during the transfer process.

[0041] The implementation principle of this application embodiment is as follows: In actual operation, when the fixed seat 22 is located at the starting end of the conveying direction, the axis of the positioning pin 222 is set vertically. The operator first fixes the nut on the positioning pin 222, and then controls the clamping part 231 on the clamping cylinder 23 to further clamp the nut on the fixed positioning pin 222. By operating the rodless cylinder 11, the conveying frame 12 is driven to move the nut forward automatically. When the conveying frame 12 is conveyed to a position close to the first support rod 131, the first sensor 132 on the first support rod 131 can detect whether there is a nut on the fixed seat 22. If there is a nut, the rodless cylinder 11 will drive the conveying frame 12 to continue to move forward; if there is no nut, the rodless cylinder 11 will drive the conveying frame 12 to return to the starting point.

[0042] When the conveyor frame 12 reaches the end of the conveying direction, the tilting cylinder rotates the fixed seat 22 90 degrees clockwise, so that the axis of the positioning pin 222 is set horizontally. Thus, the tilting of the fixed seat 22 drives the nut to tilt. At the same time, the second sensor 3131 on the detection mechanism 3 can detect the position of the nut after it has tilted. This makes it easier for the mechanism with the tightening gun to transfer the nut on the fixed seat 22 to the next process through the tightening gun, which greatly improves the automation level of the production line, reduces manual intervention, and improves production efficiency.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
