[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] Depend on Figures 1 to 5 The device includes a mounting frame 1, a support plate 2 fixedly connected to the upper end of the mounting frame 1, a U-shaped lifting groove 3 on the support plate 2, a movable plate 4 slidably connected to the front side of the mounting frame 1 located in front of the support plate 2, a V-shaped movable groove 5 on the movable plate 4, a lifting rod 6 at the front of the mounting frame 1, a movable pin 7 fixedly connected to the upper side of the lifting rod 6 located in the movable groove 5, the rear side of the movable pin 7 located in the lifting groove 3, a lifting plate 8 fixedly connected to the lower end of the lifting rod 6, clamping plates 9 on the left and right sides of the lifting plate 8 respectively, a clamping assembly on the upper side of the lifting plate 8, the clamping assembly can drive the left and right lifting plates 8 to move relative to each other or back to back, and a drive assembly on the upper rear side of the mounting frame 1, the drive assembly can drive the movable plate 4 to move left and right.

[0020] As shown in the figure, the mounting frame 1 facilitates the fixed installation of the whole. The support plate 2, lifting groove 3, moving plate 4, movable groove 5, lifting rod 6 and moving pin 7 are set up so that the moving plate 4 can drive the lifting rod 6 to move left and right. When the lifting rod 6 reaches the left and right sides of the lifting groove 3, it can be lifted and lowered. This achieves the purpose of left and right movement and lifting and lowering. The structure is simple and easy to operate. The lifting plate 8, clamping plate 9 and clamping component are set up so that the lifting rod 6 can drive the lifting plate 8 to move up and down. The clamping component can be used to grab or put the box through the clamping plate 9 to achieve the purpose of automatically grabbing and transferring the box. The structure is simplified and the grabbing and putting can be achieved without the need for a second power equipment.

[0021] The clamping assembly includes a drive plate 10, which is slidably connected to the lifting rod 6. The drive plate 10 has two symmetrical inclined slots 11 on its left and right sides respectively. The upper end of the clamping plate 9 is fixedly connected to a drive pin 12 that can be inserted into the corresponding inclined slot 11. The drive plate 10 has a connecting slot 13 in the middle. The rear end of the lifting rod 6 has a rotatable turntable 14. The rear end of the turntable 14 is fixedly connected to a connecting pin 15 located in the connecting slot 13.

[0022] As shown in the figure, the drive plate 10, inclined groove 11, drive pin 12, connecting groove 13, turntable 14 and connecting pin 15 are set up so that the drive plate 10 can be raised and lowered by the rotation of the turntable 14. The inclined groove 11 and drive pin 12 can drive the two clamping plates 9 to move relative to each other or away from each other, so as to achieve the purpose of clamping or placing the box.

[0023] The front end of the turntable 14 is fixedly connected to a gear 16. The left and right sides of the lifting rod 6 are respectively slidably connected to racks 17 that can mesh with the gear 16. The upper end of the rack 17 is fixedly connected to an L-shaped contact rod 18. The left and right sides of the front end of the mounting bracket 1 are respectively fixedly connected to contact blocks 19. The contact rod 18 can contact the contact block 19 on its corresponding side.

[0024] As shown in the figure, the gear 16, rack 17, contact rod 18, and contact block 19 are configured so that the contact rod 18 can contact the contact block 19 on its corresponding side, and the rack 17 can drive the gear 16 to rotate. When the contact rod 18 on the left side contacts the contact block 19, the gear 16 rotates, and the clamping assembly drives the two clamping plates on the left and right to move in opposite directions to release the box. When the contact rod 18 on the right side contacts the contact block 19 on the right side, the clamping assembly drives the two clamping plates on the left and right to move relative to each other to clamp the box.

[0025] The mounting frame 1 has a balance groove 20 at its front end, and a balance frame 21 is slidably connected in the balance groove 20. The lifting rod 6 has a connecting groove 22 at its rear end, and the balance frame 21 is located in the connecting groove 22. An inverted L-shaped push-pull rod 23 is slidably connected to the front side of the lifting rod 6. The upper side of the push-pull rod 23 can contact the upper end of the balance frame 21. A toothed plate 24 is fixedly connected to the lower end of the push-pull rod 23, and the toothed plate 24 can mesh with the gear 16.

[0026] As shown in the figure, the balance mechanism, balance frame 21 and connecting groove 22 can prevent the lifting rod 6 from tilting when it moves left and right, ensuring that it can always remain vertical and downward. The push-pull rod 23 and toothed plate 24 can be used by the balance frame 21 to drive the push-pull rod 23 to rise, so that the toothed plate 24 can disengage from the tooth groove, thereby releasing the limit on the gear 16 and allowing the gear 16 to rotate normally.

[0027] The front end of the push-pull rod 23 is fixedly connected to a straight rod 25, which can be slidably connected to the lifting rod 6. A return spring 26 located between the toothed plate 24 and the lifting rod 6 is sleeved on the lower side of the straight rod 25.

[0028] As shown in the figure, the straight rod 25 and the return spring 26 are set so that when the balance frame 21 contacts the push-pull rod 23, the return spring 26 retracts. When the balance frame 21 descends, the return spring 26 can drive the toothed plate 24 to mesh with the gear 16, locking the position of the gear 16 and preventing it from rotating randomly, thereby achieving smooth transfer after clamping the box.

[0029] The drive assembly includes two left and right opposite pulleys 27, which are rotatably connected to the support plate 2 respectively. The two pulleys 27 are connected by a toothed belt 28. The support plate 2 has a relief groove 29. The rear end of the moving plate 4 is fixedly connected to a relief pin 30 located in the relief groove 29. The rear end of the relief pin 30 is fixedly connected to the lower side of the toothed belt 28.

[0030] As shown in the figure, the pulley 27, toothed belt 28, relief groove 29 and relief pin 30 are set so that the pulley 27 can drive the relief pin 30 to move left and right via the toothed belt 28, thereby realizing the left and right movement of the moving plate 4. This enables the robot arm to move left and right as well as up and down. At the same time, after descending to the appropriate position at the lower end, it drives the gripping plate 9 to move relative to or away from each other, thereby realizing the gripping or placement of the box.

[0031] A drive motor 31 is fixedly connected to the mounting bracket 1, and the output end of the drive motor 31 is coaxially fixedly connected to the rear end of the pulley 27 on the left side.

[0032] As shown in the figure, the drive motor 31 can drive the pulley 27 to rotate, thereby driving the equipment to operate.

[0033] When this utility model is in use, the drive motor 31 is started. The drive motor 31 drives the moving plate 4 to move to the left via the drive assembly. The moving pin 7 then drives the lifting rod 6 and the lifting plate 8 to move left and right, as well as up and down. When moving to the left, the moving pin 7 enters the left inclined groove of the movable groove 5, and the lifting rod 6 descends. When it descends to a certain height, the balance frame 21 contacts the push-pull rod 23, and the push-pull rod 23 pulls the toothed plate 24 to remain stationary. The lifting plate 8 continues to descend. When the left contact rod 18 contacts the left contact block 19, the left rack 17 drives the gear 16 to rotate. The gear 16 drives the drive plate 10 to move downward via the connecting groove 13 and the connecting pin 15. The inclined groove 11 and the drive pin 12 then drive the clamping plates 9 on the left and right sides to move in opposite directions, thereby realizing the transfer and delivery of the box.

[0034] After placement, the drive motor 31 is reversed, causing the moving plate 4 to move to the right. During the movement of the moving plate 4 to the right, the lifting rod 6 rises, and the push-pull rod 23 descends relative to the lifting rod 6. The toothed plate 24 contacts the gear 16 and continues to limit the gear 16. Then, the lifting rod 6 moves to the upper limit position and begins to move to the right. When it reaches the right limit position, the lifting rod 6 moves downward under the action of the lifting groove 3. The push-pull rod 23 contacts the balance frame 21 again, releasing the limit on the gear 16. Then, the contact rod 18 on the right side contacts the contact block 19 on the right side, and the clamping plates 9 on both sides move relative to each other to clamp the box. After clamping, the drive motor 31 rotates forward, and the box is lifted after clamping to begin the transfer. This process of grabbing, transferring, and placing the box can be completed. This process can be repeated to complete the directional transfer of all boxes.

[0035] In this utility model, the drive motor 31 is existing technology and will not be described in detail here.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
