Description

Technical Field

[0001] The present application relates to the field of mechanical processing technology, and in particular to a clamping mechanism and a loading and unloading device. Background Art

[0002] For some workpieces, for example, the workpiece has an abutting surface and an abutting surface adjacent to the abutting surface. When the abutting surface of the workpiece and part of the abutting surface of the workpiece need to be colored, it is necessary to ensure that the workpiece will not be scratched during placement. Currently, two clamping jaws are usually driven by a driving member to approach each other to clamp the abutting surface of the workpiece that does not need to be colored. However, in this clamping method, the workpiece is easy to move relative to the clamping jaw during placement, so that the abutting surface of the workpiece that needs to be colored is scratched by the clamping jaw, and the workpiece is also easy to move toward the driving member during placement, so that the abutting surface of the workpiece that needs to be colored is scratched by the driving member. Utility Model Content

[0003] In view of the above, it is necessary to propose a clamping mechanism and a loading and unloading device to solve the technical problem that the abutting surface and the abutting surface of the workpiece that need to be colored are easily scratched during placement and removal.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0072] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0073] See also Figure 1 and Figure 2One embodiment of the present application provides a clamping mechanism 100 for clamping a workpiece 200. The workpiece 200 has a contact surface 210 and two contact surfaces 220 adjacent to the contact surface 210. Each contact surface 220 is concavely provided with a clamping groove 230. In this embodiment, the workpiece 200 is a T-shaped structure, the contact surface 220 is a stepped surface, and the clamping groove 230 is a V-shaped groove. Specifically, the clamping mechanism 100 includes a base 10, a clamping assembly 20, and a detection assembly 30.

[0074] The base 10 is a T-shaped structure. The clamping assembly 20 includes a clamping drive 21 and two clamping members 22. The clamping drive 21 is disposed on one side of the base 10. In this embodiment, the clamping drive 21 is a bidirectional cylinder. The two clamping members 22 are respectively connected to the two driving ends of the clamping drive 21 so as to move closer to or farther from each other under the drive of the clamping drive 21. Each clamping member 22 includes a supporting portion 221 for supporting a supporting surface 220 and an extending portion 222 connected to the supporting portion 221 and for extending into the card slot 230. The two extending portions 222 are located between the two supporting portions 221. The detection assembly 30 is disposed on one side of the clamping driving member 21, and is used to detect whether the position of the workpiece 200 is correctly placed, and elastically abuts the abutting surface 210 when the position of the workpiece 200 is correctly placed; wherein the clamping driving member 21 drives the two clamping members 22 to approach each other when the position of the workpiece 200 is correctly placed, so that the extending portion 222 extends into the clamping slot 230 and the abutting portion 221 abuts against the abutting surface 220, thereby clamping the workpiece 200. In this embodiment, when the position of the workpiece 200 is incorrectly placed, the workpiece 200 needs to be rotated 180 degrees in the horizontal direction so that the workpiece 200 can reach the correct position.

[0075] The above-mentioned clamping mechanism 100 first detects whether the position of the workpiece 200 is correctly placed through the detection component 30, and elastically abuts the abutting surface 210 when the position of the workpiece 200 is correctly placed, and then drives the two clamping members 22 to approach each other through the clamping driving member 21 when the position of the workpiece 200 is correctly placed, so that the insertion portion 222 is inserted into the card slot 230 and the abutting portion 221 is abutted against the abutting surface 220, thereby clamping the workpiece 200. Since the insertion portion 222 can be inserted into the card slot 230 of the workpiece 200, the insertion portion 222 can form a limit for the workpiece 200 after clamping, which can effectively prevent relative movement between the clamping member 22 and the workpiece 200, thereby avoiding the problem of the abutting surface 210 and the abutting surface 220 of the workpiece 200 being scratched during placement and pick-up, and the clamping stability is better.

[0076] See also Figure 3In some embodiments, a detection groove 211 is provided on the abutment surface 210, and the detection assembly 30 includes a fixing member 31 and an elastic abutment member 32. The fixing member 31 is a hollow structure, and the fixing member 31 is arranged on one side of the clamping driving member 21, and one end of the fixing member 31 extends between the two clamping members 22; the elastic abutment member 32 is connected to one end of the fixing member 31 extending between the two clamping members 22, and the end of the elastic abutment member 32 away from the fixing member 31 is used to elastically abut the abutment surface 210 when the position of the workpiece 200 is correctly placed, and the end of the elastic abutment member 32 away from the fixing member 31 is used to extend into the detection groove 211 when the position of the workpiece 200 is incorrectly placed. By setting the elastic abutment 32, when the workpiece 200 is correctly positioned, the elastic abutment 32 can elastically abut against the abutment surface 210 of the workpiece 200 during the process of the clamping member 22 clamping the workpiece 200, thereby preventing the abutment surface 210 of the workpiece 200 from being scratched, and whether the position of the workpiece 200 is correctly placed can be detected by whether the elastic abutment 32 elastically abuts against the abutment surface 210 of the workpiece 200.

[0077] In some embodiments, the elastic abutment member 32 includes an elastic portion 321 and an adsorption portion 322, wherein the elastic portion 321 is disposed in the fixing member 31; the adsorption portion 322 is connected to one end of the fixing member 31 extending between the two clamping members 22, and the two ends of the elastic portion 321 respectively abut the fixing member 31 and the adsorption portion 322, and the end of the adsorption portion 322 away from the fixing member 31 is used to elastically abut the abutment surface 210 when the position of the workpiece 200 is correctly placed, and the end of the adsorption portion 322 away from the fixing member 31 is used to extend into the detection slot 211 when the position of the workpiece 200 is incorrectly placed. In this embodiment, the adsorption portion 322 is connected to a negative pressure gauge (not shown in the figure), and if the negative pressure gauge connected to the adsorption portion 322 has a signal, it indicates that the position of the workpiece 200 is correctly placed, and if the negative pressure gauge connected to the adsorption portion 322 has no signal, it indicates that the position of the workpiece 200 is incorrectly placed. In this embodiment, the elastic portion 321 is a spring, the adsorption portion 322 is a suction cup, and the adsorption portion 322 is connected to the fixing member 31. The suction cup is made of a flexible material, and by providing the elastic portion 321 , the impact and scratches on the abutting surface 210 of the workpiece 200 can be effectively reduced.

[0078] See also Figure 4In some embodiments, the clamping mechanism 100 further includes a sensing member 40, which is disposed on one side of the clamping drive member 21 and is used to emit a sensing signal toward the workpiece 200 to confirm whether the position of the workpiece 200 is correctly placed. In this embodiment, the clamping mechanism 100 further includes two support plates 50 and a mounting plate 60, the support plates 50 are I-shaped structures, the two support plates 50 are disposed on opposite sides of the clamping drive member 21, the mounting plate 60 is disposed on the side of the clamping drive member 21 away from the base 10 and is respectively connected to the two support plates 50, and the sensing member 40 is disposed on the mounting plate 60. A sensing hole 212 adapted to the sensing member 40 is disposed on the abutting surface 210, and when the position of the workpiece 200 is incorrectly placed, the sensing member 40 can receive the sensing signal reflected by the workpiece 200; when the position of the workpiece 200 is correctly placed, the sensing signal emitted by the sensing member 40 passes through the sensing hole 212, and the sensing member 40 cannot receive the sensing signal reflected by the workpiece 200.

[0079] In some embodiments, the abutting portion 221 includes a connecting portion 2211 and a bending portion 2212, the two ends of the connecting portion 2211 are respectively connected to the driving end of the clamping driving member 21 and the bending portion 2212, the bending portion 2212 is bent in an arc shape relative to the connecting portion 2211, and the extending portion 222 is connected to one end of the bending portion 2212 away from the connecting portion 2211. In this embodiment, the clamping mechanism 100 also includes two connecting plates 70, the two connecting plates 70 are respectively connected to the two ends of the clamping driving member 21, and two clamping members 22 are arranged on each connecting plate 70 at intervals. In this way, it can be ensured that the extending portion 222 extends into the card slot 230 and the abutting portion 221 abuts against the abutting surface 220, and the clamping stability is good.

[0080] In some embodiments, a guide hole 213 is provided at the bottom of the detection groove 211, and the clamping mechanism 100 also includes a guide member 80, which is arranged on the mounting plate 60 on the side of the clamping drive member 21 away from the base 10 and is located between the two clamping members 22. The guide member 80 is used to be inserted into the guide hole 213 of the workpiece 200 when the position of the workpiece 200 is correctly placed to correct the position of the workpiece 200. In this embodiment, the guide member 80 is a guide pin, and the end of the guide member 80 is a tapered surface. When the clamping mechanism 100 moves toward the workpiece 200, the end of the guide member 80 first enters the guide hole 213 of the workpiece 200, and the tapered surface of the end of the guide member 80 is used to guide and position the workpiece 200; if the four clamping members 22 have a long service life and the clamping force surface of the abutting portion 221 of the clamping member 22 is severely worn and not replaced in time, the workpiece 200 will not be clamped tightly enough. This guide member 80 can effectively limit the sliding of the workpiece 200 in the horizontal direction, and can effectively avoid the risk of the workpiece 200 detaching from the clamping member 22.

[0090] The pallet 1 filled with unprocessed workpieces 200 is placed on the pallet positioning mechanism 400, and the pallet 1 is positioned by the pallet positioning mechanism 400;

[0091] The moving mechanism 500 drives the clamping mechanism 100 to move toward the pallet positioning mechanism 400 to a preset position. If the negative pressure gauge connected to the adsorption portion 322 has a signal, it indicates that the end of the adsorption portion 322 away from the fixing member 31 contacts the abutting surface 210, and the position of the workpiece 200 is correctly placed. At this time, the two clamping members 22 are driven to approach each other by the clamping driving member 21, so that the extending portion 222 extends into the card slot 230 and the abutting portion 221 abuts against the abutting surface 220, thereby clamping the workpiece 200; if the negative pressure gauge connected to the adsorption portion 322 has no signal, it indicates that the end of the adsorption portion 322 away from the fixing member 31 extends into the detection slot 211, and the position of the workpiece 200 is incorrect. At this time, the moving mechanism 500 The mechanism 500 drives the clamping mechanism 100 to move away from the pallet positioning mechanism 400, and the rotating driving member 410 drives the bearing seat 420 to rotate, for example, 180 degrees to adjust the position of the workpiece 200. Then, the moving mechanism 500 continues to drive the clamping mechanism 100 to move toward the pallet positioning mechanism 400 to a preset position. At this time, the end of the adsorption portion 322 away from the fixing member 31 contacts the abutting surface 210, and then the clamping driving member 21 of the clamping mechanism 100 drives the two clamping members 22 to approach each other, so that the extending portion 222 extends into the card slot 230 and the abutting portion 221 abuts against the abutting surface 220, thereby clamping the workpiece 200, and then the negative pressure gauge is used to detect whether the clamping member 22 clamps the workpiece 200.

[0092] If the clamping member 22 clamps the workpiece 200, the moving mechanism 500 drives the clamping mechanism 100 to move toward the workpiece positioning mechanism 700, and the workpiece 200 removed from the tray positioning mechanism 400 is placed on the padding member 720 of the workpiece positioning mechanism 700, the clamping driving member 21 is released, the workpiece 200 falls, and the workpiece 200 is guided and positioned by the positioning member 730, and then the moving mechanism 500 drives the clamping mechanism 100 to remove the workpiece 200 on the padding member 720;

[0093] The moving mechanism 500 drives the clamping mechanism 100 to move toward the processing jig 800, and places the workpiece 200 removed from the workpiece positioning mechanism 700 on the support seat 820 of the processing jig 800. The telescopic driving member 830 drives the positioning head 840 to pass through the support seat 820 and extend into the workpiece 200 carried by the support seat 820. Then, the rotating driving member 810 drives the support seat 820 to rotate, so that the positioning head 840 locks the workpiece 200 carried by the support seat 820.

[0094] The moving mechanism 500 drives the processing mechanism 600 to move toward the processing jig 800, so that the processing mechanism 600 processes the workpiece 200 on the processing jig 800;

[0095] After processing, the moving mechanism 500 drives the clamping mechanism 100 to remove the workpiece 200 on the processing fixture 800 and place it in the pallet 1 on the pallet positioning mechanism 400. After the pallet 1 is full of workpieces 200, the pallet 1 full of processed workpieces 200 is taken away, and a new pallet 1 full of unprocessed workpieces 200 is placed on the pallet assembly 430.
