Description

Technical Field

[0001] The present invention relates to the technical field of material transfer equipment, and particularly relates to a transfer device for fixed-point transfer within a plane. Background Art

[0002] Material transfer is the most commonly used process in industrial production. For feeding, materials need to be moved from the raw material storage location to the processing location. Semi-finished products need to be transferred from one processing device to another. After the raw materials are processed into finished products, the finished products need to be unloaded from the processing device. Therefore, all links in industrial production involve the transfer of products or materials. Existing transfers are generally completed by manipulators, conveyor belts, etc. Manipulators have high flexibility and can control the specific picking, placing positions and moving paths more according to needs. Conveyor belts have a large transportation volume and are suitable for large-scale continuous movement. However, for the transfer of some materials, point-to-point directional transfer is required. Although manipulators have high flexibility, there are problems with the stability and consistency of the transfer path. Conveyor belts have a large transportation volume, but the movement path is too single and can only be transferred within a horizontal plane, so they cannot complete accurate transfer between points. Therefore, both manipulators and conveyor belts are not suitable for point-to-point directional transportation within a plane. Summary of the Invention

[0003] The technical problem solved by the present invention is to provide a transfer device for fixed-point transfer within a plane in view of the deficiencies in the background art.

[0004] To solve the above technical problem, the technical solution of the present invention is: a transfer device, including a fixed plate, a first movable plate slidably arranged on the fixed plate, a second movable plate slidably arranged on the first movable plate, and a third movable plate slidably arranged on the second movable plate; a first cam mechanism is provided between the fixed plate and the first movable plate to drive the first movable plate to move relatively and drive the second movable plate in a linked manner; a second cam mechanism is provided between the fixed plate and the third movable plate to drive the third movable plate to move relatively and drive the second movable plate in a linked manner. Thus, the first movable plate and the third movable plate can respectively perform one-dimensional movements on the fixed plate, and the second movable plate connected to the first movable plate and the third movable plate can perform two-dimensional movements, and the product can be transferred through the second movable plate.

[0005] Further, the sliding direction of the second movable plate is perpendicular to the sliding direction of the first movable plate, and the sliding direction of the third movable plate is perpendicular to the sliding direction of the second movable plate. Thus, the second movable plate can move in two dimensions, horizontal and vertical, on the fixed plate.

[0006] Further, it further includes a second gear, and both the first cam mechanism and the second cam mechanism are driven by meshing with the second gear. Thus, the first cam mechanism and the second cam mechanism are linked, and the first cam mechanism and the second cam mechanism can be driven by one driving mechanism.

[0007] Further, the second cam mechanism includes an annular groove cam, and the third movable plate is connected to the fixed plate through the annular groove cam. Thus, the third movable plate and the fixed plate are cam-driven and connected.

[0008] Further, the second cam mechanism further includes an annular gear that is connected to and guides the third movable plate; and further includes a third gear that is drivingly connected to the second gear and meshes with the annular gear. Thus, the movement of the third movable plate on the fixed plate is guided by the annular groove cam and driven by the annular gear, with stronger load-bearing capacity.

[0009] Further, an execution end is provided on the second movable plate. Thus, the execution end is provided for material picking.

[0010] Further, the fixed plate and the first movable plate, the first movable plate and the second movable plate, and the second movable plate and the third movable plate are all connected through a slide rail structure. Thus, a specific connection method between the fixed plate and the first movable plate, the first movable plate and the second movable plate, and the second movable plate and the third movable plate is provided.

[0011] Further, the first cam mechanism is coaxially and fixedly connected to the first gear, and the first cam mechanism and / or the first gear are rotatably provided on the fixed plate. Thus, a specific setting method for the first cam mechanism and the first gear is provided.

[0012] Further, a first driving block is provided on the first movable plate, and the first driving block is adapted to the first cam mechanism. Thus, the connection between the first movable plate and the fixed plate is ensured.

[0013] Further, a second driving block is provided on the third movable plate, and the second driving block is adapted to the annular groove cam. Thus, the connection between the third movable plate and the fixed plate is ensured.

[0014] The beneficial effects achieved by the present invention are mainly as follows: The material transfer is realized through two cam mechanisms, one fixed plate, and three movable plates. The transfer stroke can be independently designed and controlled, facilitating the selection of the stroke in each direction according to needs; The annular groove cam and the annular gear are used together to drive the third movable plate, enabling the second movable plate connected to the third movable plate to bear a greater force, that is, the moving direction of the third movable plate. Therefore, the moving direction of the third movable plate is often taken as the vertical direction to bear the gravity. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] For the convenience of those skilled in the art to understand, the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0019] Embodiment 1

[0020] Refer to Figure 1 and Figure 2 , a transfer device, including a first movable plate 1, a second movable plate 2, a third movable plate 3, a fixed plate 4, an execution end 5, a first cam mechanism 6 and a second cam mechanism 7. The fixed plate 4 is fixedly arranged and can be fixedly connected to structures such as a vertical frame. The first movable plate 1 is slidably arranged on the fixed plate 4, the second movable plate 2 is slidably arranged on the first movable plate 1, the third movable plate 3 is slidably arranged on the second movable plate 2, the sliding direction of the second movable plate 2 is perpendicular to the sliding direction of the first movable plate 1, the sliding direction of the third movable plate 3 is parallel to the sliding direction of the first movable plate 1, and the execution end 5 is arranged on the second movable plate 2. Therefore, the execution end 5 can slide in two dimensions together with the second movable plate 2. For example, it can slide in the X direction relative to the third movable plate 3 and slide in the Y direction relative to the first movable plate 1.

[0021] Refer to Figure 1 and 2 , the first cam mechanism 6 is connected between the fixed plate 4 and the first movable plate 1, so that the first cam mechanism 6 can provide power for the first movable plate 1 in the sliding direction of the first movable plate 1 and limit the stroke of the first movable plate 1 in this direction. The second cam mechanism 7 is connected between the fixed plate 4 and the third movable plate 3, so that the second cam mechanism 7 can provide power for the third movable plate 3 in the sliding direction of the third movable plate 3 and limit the stroke of the third movable plate 3 in this direction. Since the second movable plate 2 is slidably arranged on the first movable plate 1 and the sliding direction is perpendicular to the sliding direction of the first movable plate 1, the second movable plate 2 can slide in the sliding direction of the first movable plate 1 together with the first movable plate 1, that is, in Figure 1Slide in the Y direction of the middle. Also, since the second movable plate 2 is slidably arranged on the third movable plate 3 and the sliding direction is perpendicular to the sliding direction of the third movable plate 3, the second movable plate 2 can slide along with the third movable plate 3 in the sliding direction of the third movable plate 3, that is, in Figure 1 Slide in the X direction of the middle. Thus, the execution end 5 realizes sliding in two directions of X and Y. When moving continuously, the movement trajectory of the execution end 5 is fixed and material transfer can be carried out. The execution end 5 can select a suction cup, a gripper, etc., and select according to the needs of transferring materials. The material transfer is realized through two cam mechanisms, a fixed plate, and three movable plates. The strokes in the X and Y directions of the transfer can be independently designed and controlled, which is convenient to select the strokes in the X and Y directions according to the needs.

[0022] Refer to Figure 2 , the first cam mechanism 6 is connected to the first gear 8, the second cam mechanism 7 is connected to the second gear 9, and the first gear 8 meshes with the second gear 9. Thus, a driving device such as a driving motor can be drivingly connected to the first gear 8 or the second gear 9 to simultaneously drive the first cam mechanism 6 and the first gear 8, that is, drive the movements in two directions, making the device more portable and saving material costs.

[0023] Refer to Figure 2 , the first cam mechanism 6 is fixedly connected to the first gear 8 coaxially. The first cam mechanism 6 and / or the first gear 8 is rotatably arranged on the fixed plate 4 and can be installed through bearings. The first movable plate 1 is provided with a first driving block 11, and the first driving block 11 is adapted to the first cam mechanism 6, that is, the first cam mechanism 6 can drive the first driving block 11 to move, thereby driving the first movable plate 1 fixedly connected to the first driving block 11. The first cam mechanism 6 is preferably a grooved gear, and the first driving block 11 is provided with a roller that cooperates with the grooved gear. The connection between the first cam mechanism 6 of the grooved gear and the first driving block 11 is more convenient. A general cam can also be used, and in this case, a position limiting mechanism such as a spring needs to be set.

[0024] The second driving block is adapted to the second cam mechanism 7. The second cam mechanism 7 can also be arranged in the same way as the first cam mechanism 6 and will not be elaborated here. Hereinafter, a second cam mechanism 7 arranged in another way is provided. Refer to Figure 1 and Figure 2, the second cam mechanism 7 is fixedly arranged on the fixed plate 4. The third movable plate 3 is provided with a second driving block (on the back of the third movable plate 3, not shown in the figure). Specifically, the second cam mechanism 7 includes an annular groove cam 71. The two sides of the annular groove cam 71 are arc-shaped grooves and the middle is a straight groove. The annular groove cam 71 is fixedly arranged on the fixed plate 4. The second driving block is slidably arranged in the annular groove cam 71. A roller matching the groove of the annular groove cam 71 can be arranged on the second driving block for sliding. The second cam mechanism 7 includes an annular gear 72. The annular gear 72 is fixedly arranged on the third movable plate 3. It further includes a third gear 10. The third gear 10 is coaxially and fixedly connected with the second gear 9. The third gear 10 meshes with the annular gear 72. Thus, the cooperation between the annular groove cam 71 and the second driving block can play a role in positioning. The power for the third movable plate 3 to move in the annular groove cam 71 is provided by the meshing of the third gear 10 and the annular gear 72. Therefore, the annular gear 72 and the annular groove cam 71 have the same contour to enable driving with the same motion trajectory. Using the annular groove cam and the annular gear in cooperation to drive the third movable plate 3 can enable the second movable plate 2 connected to the third movable plate 3 to bear greater force, that is Figure 1 the force in the Y direction in

[0025] Refer to Figure 1 , the running trajectory of the execution end 5 is as shown in the figure. The length a in the X direction in the trajectory is determined by the longer side of the annular groove cam and the annular gear. In the figure, it is the side that is not horizontal. The length b in the Y direction in the trajectory is determined by the first cam mechanism. Additionally, the running trajectory is adjusted by the installation positions of the first cam mechanism and the annular groove cam.

[0026] Refer to Figure 1 and Figure 2 , between the fixed plate 4 and the first movable plate 1, between the first movable plate 1 and the second movable plate 2, and between the second movable plate 2 and the third movable plate 3 are all connected through a slide rail structure, that is, a structure in which a guide rail cooperates with a chute. The fixed plate 4 plays a role in fixing other parts. The fixed plate 4 can also be provided with structures such as a base for convenient fixing, and can also be provided with rib plates and other structures to enhance the structural strength. The first movable plate 1, the second movable plate 2, and the third movable plate 3 can all adopt a frame structure, which can reduce the weight of the equipment while ensuring the strength. For example, the first movable plate 1 can directly adopt two strip-shaped structures, and the second movable plate 2 and the third movable plate 3 can adopt a frame-shaped structure.
