Description

Technical Field

[0001] The present application relates to the technical field of material pushing mechanisms, and in particular to a material pushing mechanism for grabbing continuous material pieces. Background Art

[0002] Reference Figure 1 The connecting piece 4 is used to connect the connecting piece A 41 and the connecting piece B 42 into one piece by spot welding, and the connecting piece 4 is grasped and welded by a robot. Since there is an oil film on the surface of the connecting piece 4, two adjacent connecting pieces 4 are prone to adhesion. When grasping, the robot grasps a double connecting piece. If the double connecting piece is grasped and welded into a finished connecting piece, when the finished connecting piece enters the stamping die, it will cause the scrapping of the parts or even damage to the stamping die. Utility Model Content

[0003] In order to reduce the occurrence of a situation where a robot arm grabs double connected sheets when grabbing connected sheets, the present application provides a pushing mechanism for grabbing connected sheets.

[0004] The present application provides a material pushing mechanism for grabbing continuous material pieces, which adopts the following technical solution:

[0005] A material pushing mechanism for grabbing a continuous material piece comprises a bottom plate, a column, a slider and a pushing member, wherein a pushing groove is provided on the top surface of the bottom plate, and a mounting through groove is formed in the middle of the bottom plate, wherein the mounting through groove is located inside the pushing groove and communicated with the pushing groove;

[0006] The columns are fixedly arranged on the top surface of the bottom plate and are located on both sides of the installation slot. The columns on both sides are provided with slots for the two ends of the connecting piece to be clamped on one side close to each other. The slots pass through the tops of the columns. The connecting pieces are stacked in the slots and supported on the bottom wall of the push slot. One side of the columns close to the width direction of the connecting piece is the discharge side. A clearance slot is formed between the bottom surface of the discharge side and the bottom wall of the push slot. The height of the clearance slot is slightly equal to the thickness of a single connecting piece.

[0007] The slider is slidably arranged in the installation slot through a pushing member, the sliding direction of the slider is parallel to the plate surface direction of the bottom plate, the top surface of the slider is located between the bottom surface and the top surface of the lowest connecting piece, and the slider is used to push the lowest connecting piece out of the clearance slot.

[0008] By adopting the above technical solution, the connecting piece is located in the card slot, and a channel that can only allow one connecting piece to pass through is formed at the clearance slot. The slider is pushed by the pusher to slide, and the slider pushes the connecting piece to exit from the clearance slot. Since the height of the clearance slot can only allow one connecting piece to pass through, there will not be two connecting pieces in the position to be grasped. According to the actual situation, it can be set that after the slider is pushed into place, it stays for 1 second and starts to slide in the opposite direction to reset. The connecting piece to be pushed in the card slot slides down due to gravity and waits to be pushed out next time, thereby reducing the situation where the robot arm grasps double connecting pieces when grasping the connecting piece.

[0009] Optionally, the column includes a first vertical plate, a second vertical plate and a third vertical plate connected in sequence by bolts, and the slot is surrounded by the first vertical plate, the second vertical plate and the third vertical plate;

[0013] By adopting the above technical solution, when installing the column, the third vertical plate is first fixed to the bottom plate through the mounting plate, and then the first vertical plate and the second vertical plate are fixed to the third vertical plate, so the installation is quick and convenient. The waist-shaped hole is set to facilitate the adjustment of the distance between the two third vertical plates for fine adjustment, thereby facilitating the adaptation of the length of the connecting piece.

[0014] Optionally, a height limiting block is provided on the discharge side, and the bottom surface of the height limiting block is flush with the bottom surface of the second vertical plate.

[0015] By adopting the above technical solution, the slider pushes the lowest connecting piece out of the clearance groove and the bottom of the height limit block in turn, further reducing the occurrence of double connecting pieces and helping to improve the stability of the slider in the process of pushing the connecting piece to move.

[0016] Optionally, the height limiting block is arranged on the discharge side through an L-rod, one side of the L-rod is connected to the top surface of the height limiting block through a bolt, and the other side of the L-rod is connected to the discharge side through a bolt.

[0017] By adopting the above technical solution, the installation of the height limiting block is facilitated.

[0018] Optionally, a counterweight block is placed on the uppermost connecting piece, and two ends of the counterweight block are correspondingly clamped in the clamping slots.

[0019] By adopting the above technical solution, the counterweight block can apply pressure to the connecting piece in the slot, which helps the connecting piece to fall smoothly.

[0020] Optionally, the pushing member is a pushing cylinder, and the piston rod of the pushing cylinder is fixedly connected to the sliding block via a connecting member.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a material pushing mechanism for grabbing a continuous sheet of material. Figure 1-4 The pushing mechanism for grabbing continuous material pieces includes a pushing mechanism for grabbing continuous material pieces, including a base plate 1, a column 2, a slider 3 and a pushing member. A pushing groove 11 is opened on the top surface of the base plate 1, and a mounting through groove 12 is formed in the middle of the base plate 1. The mounting through groove 12 is located on the inner side of the pushing groove 11 and is connected to the pushing groove 11.

[0037] The column 2 is fixedly arranged on the top surface of the bottom plate 1 and located on both sides of the installation slot 12. The side of the two side columns 2 close to each other is provided with a slot 21 for the two ends of the connecting piece 4 to be clamped. The slot 21 passes through the top of the column 2. The connecting piece 4 is stacked in the slot 21 and supported on the bottom wall of the push slot 11. One side of the column 2 close to the connecting piece 4 in the width direction is the discharge side 22. The bottom surface of the discharge side 22 and the bottom wall of the push slot 11 are spaced to form a clearance slot 23. The height of the clearance slot 23 is slightly the thickness of a single piece of connecting piece 4. The slider 3 is slidably arranged in the installation slot 12 through a pusher. The sliding direction of the slider 3 is parallel to the plate surface direction of the bottom plate 1. The top surface of the slider 3 is located between the bottom surface and the top surface of the lowest connecting piece 4. The slider 3 is used to push the lowest connecting piece 4 out of the clearance slot 23.

[0038] The connecting piece 4 is located in the slot 21, and a passage is formed at the clearance slot 23 that allows only one connecting piece 4 to pass through. The slider 3 is pushed by the pusher to slide, and the slider 3 pushes the connecting piece 4 out of the clearance slot 23. Since the height of the clearance slot 23 only allows one connecting piece 4 to pass through, there will not be two connecting pieces 4 in the position to be grasped. It can be set according to actual conditions. After the slider 3 is pushed into place, it stays for 1 second and starts to slide in the opposite direction to reset. The connecting piece 4 to be pushed in the slot 21 slides down due to gravity and waits to be pushed out next time, thereby reducing the situation where the robot hand grasps two connecting pieces 4 when grasping the connecting piece 4.

[0039] Reference Figure 3 The column 2 includes a first vertical plate 24, a second vertical plate 25 and a third vertical plate 26 connected in sequence by bolts, and the slot 21 is surrounded by the first vertical plate 24, the second vertical plate 25 and the third vertical plate 26. The first vertical plate 24 and the second vertical plate 25 are arranged opposite to each other, and the discharge side 22 is the side of the second vertical plate 25 away from the first vertical plate 24, and the clearance groove 23 is located at the bottom surface of the second vertical plate 25, which is convenient for the formation of the slot 21, and has a simple structure and is easy to install.

[0040] Reference Figure 3 The outer side of the bottom end of the third vertical plate 26 is fixedly connected with a mounting plate 261, and a waist-shaped hole 262 is provided on the top surface of the mounting plate 261, and the length direction of the waist-shaped hole 262 is parallel to the length direction of the connecting piece 4. When installing the column 2, the third vertical plate 26 is first fixed to the bottom plate 1 through the mounting plate 261, and then the first vertical plate 24 and the second vertical plate 25 are fixed to the third vertical plate 26, and the installation is quick and convenient. In addition, the setting of the waist-shaped hole 262 facilitates the adjustment of the distance between the two third vertical plates 26 for fine adjustment, thereby facilitating the adaptation of the length of the connecting piece 4.

[0041] Reference Figure 1 and Figure 3 , a height limiting block 5 is provided on the discharge side 22, and the bottom surface of the height limiting block 5 is provided flush with the bottom surface of the second vertical plate 25. The slider 3 pushes the lowest connecting piece 4 out of the clearance slot 23 and the bottom of the height limiting block 5 in sequence, further reducing the occurrence of double connecting pieces 4, and helping to improve the stability of the slider 3 in the process of pushing the connecting piece 4 to move. The height limiting block 5 is provided on the discharge side 22 through an L rod 6, one side of the L rod 6 is connected to the top surface of the height limiting block 5 by bolts, and the other side of the L rod 6 is connected to the discharge side 22 by bolts, which facilitates the installation of the height limiting block 5.

[0042] Reference Figure 1 , Figure 2 and Figure 5 , Figure 6A counterweight 7 is placed on the uppermost connecting piece 4, and the two ends of the counterweight 7 are correspondingly clamped in the clamping slot 21. The counterweight 7 can apply pressure to the connecting piece 4 in the clamping slot 21, which helps the connecting piece 4 to fall smoothly. The pusher is a push cylinder 8, and the piston rod of the push cylinder 8 is fixedly connected to the slider 3 through a connecting member. The push cylinder 8 has a simple structure and is easy to install. The connecting member is a connecting plate 9, and the top of the connecting plate 9 is fixedly connected to the slider 3, which facilitates the connection between the piston rod of the push cylinder 8 and the slider 3.

[0043] The implementation principle of the push mechanism for grabbing a continuous sheet in the embodiment of the present application is as follows: the continuous sheet 4 is located in the slot 21, and a passage that can only allow one continuous sheet 4 to pass is formed at the clearance slot 23. The slider 3 is pushed to slide by the pusher, and the slider 3 pushes the continuous sheet 4 to exit from the clearance slot 23. Since the height of the clearance slot 23 can only allow one continuous sheet 4 to pass, there will not be two continuous sheets 4 in the position to be grabbed. It can be set according to actual conditions. After the slider 3 is pushed into place, it stays for 1 second and starts to slide in the opposite direction to reset. The continuous sheet 4 to be pushed in the slot 21 slides downward due to gravity and waits to be pushed out next time, thereby reducing the situation where the robot hand grabs two continuous sheets 4 when grabbing the continuous sheet 4.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
