Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a gripper and moving frame mechanism for a quantitative feeding box. Background Technology

[0002] In high-speed rail track systems, W-shaped elastic strips (also known as elastic steel strips in elastic fasteners) are a core component of the fastener system. Their role is crucial and directly relates to the stability and safety of the track structure and the smoothness of train operation.

[0003] Currently, in the production and processing of W-type spring clips, an intelligent heat treatment production line is required to process the spring clip raw materials. The specific heat treatment process is as follows: heating the spring clip raw materials, then conveying or transferring them to forming and forging equipment for forming and forging, quenching the W-type spring clip workpiece after forming to improve its overall rigidity, transferring the W-type spring clip workpiece to an annealing equipment for annealing to eliminate its surface stress, and then feeding the W-type spring clip workpiece to a shot blasting equipment for surface treatment through a feeding device.

[0004] After heat treatment, most existing spring clips are still transferred to shot blasting equipment for surface cleaning and treatment by manual handling. This traditional manual transfer mode is not only inefficient, but also significantly increases the labor intensity of workers. At the same time, due to the limited speed and stability of manual operation, it is difficult to meet the production requirements of modern automated production lines for high efficiency, high consistency and continuous operation. Therefore, it is necessary to design a gripper and moving frame mechanism for a quantitative feeding box to solve the above problems. Utility Model Content

[0005] In order to overcome the fact that in the existing technology, after the heat treatment process, the spring bars are mostly transferred to the shot blasting equipment by manual handling for surface cleaning and treatment, this traditional manual transfer mode is not only inefficient, but also significantly increases the labor intensity of workers. At the same time, due to the limited speed and stability of manual operation, it is difficult to meet the production requirements of modern automated production lines for high efficiency, high consistency and continuous operation. One of the purposes of this utility model is to provide a gripper and moving frame mechanism for a quantitative feeding box.

[0006] One of the objectives of this utility model is achieved through the following technical solution: a gripper and moving frame mechanism for a quantitative feeding bin, comprising a conveying mechanism; a quantitative weighing mechanism is provided on one side of the conveying mechanism, a bin is movably connected to the quantitative weighing mechanism, and a gripping and transferring mechanism is provided on one side of the quantitative weighing mechanism for gripping and transferring the bin; the gripping and transferring mechanism includes a guide rail, a moving trolley slidably connected to the guide rail, a three-axis robotic arm mounted on the moving trolley, and a support assembly mounted on one side of the three-axis robotic arm; the support assembly is made of... The three-axis robotic arm comprises a support plate mounted on the support plate, a vertical plate mounted on one side of the support plate, a clamping plate one and a clamping plate two symmetrically mounted on one side of the vertical plate, a support plate mounted below the vertical plate, a telescopic cylinder symmetrically mounted on the support plate, a support member mounted on one end of the telescopic cylinder, a connecting rod rotatably connected to the inner wall of the support member, a fixing plate symmetrically mounted on the vertical plate, a support shaft fixedly connected to the fixing plate, a rotating member rotatably connected to the support shaft, and a cover plate installed with the rotating member. One end of the connecting rod is fixed to the outer wall of the rotating member.

[0007] According to the aforementioned gripper and moving frame mechanism of a quantitative feeding bin, the conveying mechanism consists of a frame and a conveyor belt mounted on the frame.

[0008] According to the aforementioned gripper and moving frame mechanism for a quantitative feeding bin, the quantitative weighing mechanism consists of a base, a weighing sensor mounted on the base, a roller rotatably connected to the base, and position sensor one and position sensor two symmetrically mounted on the base. The bin is conveyed via the roller.

[0009] According to the aforementioned gripper and moving frame mechanism for a quantitative feeding bin, the height of the upper surface of the bin is lower than the height of the lower surface of the conveyor belt.

[0010] According to the aforementioned gripper and moving frame mechanism of a quantitative feeding bin, a through groove is provided on the lower surface of the bin, and the support plate is movably connected to the through groove.

[0011] According to the gripper and moving frame mechanism of the quantitative feeding box, the conveying mechanism, the quantitative weighing mechanism and the gripping and transferring mechanism are all electrically connected to the PLC control system.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] By incorporating a gripping and transfer mechanism, this device, compared to the existing manual transfer method of material boxes, automatically delivers the spring clips into the material box via a conveying mechanism, monitors the weight of the spring clips inside the material box using a quantitative weighing mechanism, and then grips and transfers the material box and its contents to the next process via the gripping and transfer mechanism. This eliminates the need for manual transfer of the material box, significantly reducing the labor intensity of workers. At the same time, the gripping and transfer mechanism integrates a rotatable cover plate, which can close the top opening of the material box to prevent the spring clips from falling out during the transfer process, effectively ensuring the safety of the material box transfer.

[0026] Reference Figures 1-5A gripper and moving frame mechanism for a quantitative feeding bin includes a conveying mechanism 1; a quantitative weighing mechanism 2 is provided on one side of the conveying mechanism 1, and a bin 3 is movably connected to the quantitative weighing mechanism 2; a gripping and transferring mechanism 4 is provided on one side of the quantitative weighing mechanism 2, the gripping and transferring mechanism 4 is used to grip and transfer the bin 3; the gripping and transferring mechanism 4 includes a guide rail 41, a moving trolley 42 slidably connected to the guide rail 41, a three-axis robotic arm 43 mounted on the moving trolley 42, and a support assembly 44 mounted on one side of the three-axis robotic arm 43; the support assembly 44 consists of a support plate 4401 mounted on the three-axis robotic arm 43, a vertical plate 4402 mounted on one side of the support plate 4401, clamping plates 4403 and 4404 symmetrically mounted on one side of the vertical plate 4402, and a support below the vertical plate 4402. The system comprises a plate 4405, a telescopic cylinder 4406 symmetrically mounted on a support plate 4401, a support member 4407 mounted on one end of the telescopic cylinder 4406, a connecting rod 4408 rotatably connected to the inner wall of the support member 4407, a fixed plate 4409 symmetrically mounted on a vertical plate 4402, a support shaft 4410 fixedly connected to the fixed plate 4409, a rotating member 4411 rotatably connected to the support shaft 4410, and a cover plate 4412 installed with the rotating member 4411. One end of the connecting rod 4408 is fixed to the outer wall of the rotating member 4411. A through groove 5 is provided on the lower surface of the material box 3, and the support plate 4405 is movably connected to the through groove 5. The system also includes a PLC control system. The conveying mechanism 1, the quantitative weighing mechanism 2, and the gripping and transferring mechanism 4 are all electrically connected to the PLC control system. (Refer to...) Figure 1 The mobile trolley 42 is self-moving and can move on the guide rail 41 on its own. It can feed the spring strips into the material box 3 through the conveying mechanism 1. The quantitative weighing mechanism 2 monitors the weight of the spring strips inside the material box 3 in real time. The gripping and transfer mechanism 4 can grip the material box 3 and the spring strips inside it as a whole and transfer them to the next process. Thus, the automated conveying, weighing, feeding and transfer methods effectively improve the convenience and practicality of the device. At the same time, it meets the production requirements of modern automated production lines for high efficiency, high consistency and continuous operation. Furthermore, the gripping and transfer mechanism 4 is integrated with a cover plate 4412 that rotates up and down. The cover plate 4412 can close the top of the material box 3, thereby preventing the spring strips inside the material box 3 from falling out from the top during the transfer process, effectively ensuring the safety of the transfer.

[0027] The conveying mechanism 1 consists of a frame 11 and a conveyor belt 12 mounted on the frame 11. The upper surface of the hopper 3 is lower than the lower surface of the conveyor belt 12. (Refer to...) Figure 3The driving source of the conveying mechanism 1 is a stepper motor installed on one side of the frame 11, a rotating shaft installed on the output end of the stepper motor, and a rotating shaft rotatably connected to the inner wall of the conveyor belt 12. The stepper motor rotates to drive the rotating shaft to rotate, and the rotating shaft drives the conveyor belt 12 to rotate through the friction between the rotating shaft and the inner wall of the conveyor belt 12. The rotation of the conveyor belt 12 drives the rotating shaft on the other side of its inner wall to rotate, thereby achieving the conveying effect. The conveying mechanism 1 can convey the elastic strip to the material box 3 for feeding.

[0028] The quantitative weighing mechanism 2 consists of a base 21, a weighing sensor 22 mounted on the base 21, a roller 23 rotatably connected to the base 21, and position sensor 24 and position sensor 25 symmetrically mounted on the base 21. The material box 3 is conveyed by the roller 23.

[0029] Reference Figure 3 The drive source for roller 23 consists of a forward and reverse stepper motor, a drive gear mounted on the output end of the forward and reverse stepper motor, a synchronous belt meshing with the outer wall of the drive gear, and a driven gear mounted on the outer wall of roller 23. The rotation of the forward and reverse stepper motor drives the drive gear to rotate, the rotation of the drive gear drives the synchronous belt to rotate, and the rotation of the synchronous belt meshes with multiple driven gears to drive the driven gears to rotate. Through the driven gears, multiple rollers 23 are driven to rotate. When the material box 3 moves under the drive of roller 23, when it is detected by position sensor 24, position sensor 24 will... The signal is transmitted to the PLC control system (not shown in the figure, set externally). The PLC control system controls the forward and reverse stepper motors to reverse and drive the material box 3 to move to one side of the position sensor 25 through the roller 23. Thus, the reciprocating motion of the material box 3 achieves the purpose of evenly distributing the spring strips inside the material box 3. The weighing sensor 22 monitors the feeding weight of the spring strips inside the material box 3 in real time. When the set feeding weight is reached, the weighing sensor 22 transmits the signal to the PLC control system. The PLC control system controls the conveying mechanism 1 to close, thereby stopping the conveying of the spring strips.

[0030] Working principle: The spring bar is conveyed to the material box 3 by the conveyor belt 12 of the conveying mechanism 1. The material box 3 moves left and right under the drive of the roller 23 to achieve the purpose of uniform material distribution. When the material reaches the weight set by the weighing sensor 22, the conveying mechanism 1 stops conveying the spring bar and starts the three-axis robotic arm 43 to drive the support assembly 44 to move to the material box 3. The support plate 4405 is inserted into the through groove 5 on the lower surface of the material box 3. The support plate 4405 supports the material box 3. The distance between the clamping plate 1 4403 and the clamping plate 2 4404 is consistent with the length of the material box 3. The two sides of the material box 3 are limited and clamped by the clamping plate 1 4403 and the clamping plate 2 4404. The telescopic cylinder 4406 is activated to push the connecting rod 4408 to rotate on the inner wall of the support member 4407. Due to the connecting rod 440... One end of the rod 8 is connected to the rotating component 4411. The rotating component 4411 is axially restricted by the support shaft 4410. Thus, the end of the connecting rod 4408 near the support component 4407 moves up and down with the support component 4407. The end of the connecting rod 4408 near the cover plate 4412 is restricted by the support shaft 4410 and does not move up and down with the connecting rod 4408. Instead, the up and down movement of the connecting rod 4408 drives the rotating component 4411 to rotate on the outer wall of the support shaft 4410, thereby causing the cover plate 4412 to rotate up and down to seal the upper surface of the material box 3. This prevents the spring bar inside the material box 3 from falling out from the upper surface during the transfer process by the gripping and transferring mechanism 4, effectively ensuring the transfer safety of the spring bar and improving the practicality of the device.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
