Description

Technical Field

[0001] This invention relates to the field of product feeding technology, and more specifically to a bidirectional automatic feeding mechanism with positioning function. Background Technology

[0002] Taking injection molded products as an example, from the completion of injection molding to the completion of the gate cutting action, a complete injection molded product or a semi-finished injection molded product is obtained. Then, the obtained product undergoes secondary processing (polishing, grinding) or direct assembly. In the process of secondary processing or assembly, it should be noted that for small injection molded products, manual feeding is inefficient and cannot meet the requirements of high-efficiency production. If mechanical feeding is used, for small injection molded products, on the one hand, it is difficult to accurately locate the gripping point of the injection molded product due to its small size, and on the other hand, it is also necessary to meet the production requirements of rapid gripping.

[0003] Therefore, this application proposes a solution. Summary of the Invention

[0004] The purpose of this invention is to provide a bidirectional automatic feeding mechanism with positioning function to solve the problems of low feeding efficiency or difficulty in quickly locating the gripping point in the injection molded product during the current feeding process.

[0005] The objective of this invention can be achieved through the following technical solution: a bidirectional automatic feeding mechanism with positioning function, comprising a base plate frame and a robotic arm, wherein the robotic arm is mounted on the base plate frame, and a material stacking structure is provided on one side of the base plate frame, the material stacking structure comprising a material plate, multiple material stacking slots and a mounting plate, the material plate being connected to the base plate frame, the multiple material stacking slots being arranged perpendicularly to the upper surface of the material plate, the mounting plate being mounted at the moving end of the robotic arm, material sliding grooves being provided at the four corners of the upper surface of the material plate, and adjusting blocks being installed on both sides of the material plate corresponding to the material sliding grooves, the material stacking slots being mounted on the adjusting blocks in a vertically upward direction, a material stacking groove being formed between two material stacking slots along the width direction of the material sliding groove, and a pushing block being slidably mounted in the material sliding groove along the length direction of the material plate, a driving structure corresponding to the pushing block being provided on the lower side of the material plate, and a suction nozzle assembly being provided on the mounting plate.

[0006] A further configuration is provided: a material trough is provided between the inner walls of the pusher blocks that are close to each other and the pusher blocks, and the diameter of the material trough is equal to the diameter of the stacking trough.

[0007] The configuration is further defined as follows: multiple product bodies are stacked in the vertical direction in the material stacking groove.

[0008] The following configuration is further defined as follows: the thickness of the product body, the thickness of the pusher block, the depth of the sliding groove, and the distance between the lower surface of the adjusting block and the bottom of the inner wall of the sliding groove are equal.

[0009] The further configuration is as follows: the suction nozzle assembly consists of four negative pressure air nozzle suction cups, which are installed in the mounting plate, and the installation positions of the four negative pressure air nozzle suction cups correspond to the settings of the material trough.

[0010] The drive structure is further configured as follows: the drive structure includes a bidirectional cylinder and two mounting blocks. The bidirectional cylinder is installed at the center point of the lower surface of the material plate. The mounting blocks are arranged in a mirror-symmetrical manner along the installation position of the bidirectional cylinder. The transmission rod of the bidirectional cylinder is connected to the mounting blocks. The mounting blocks are slidably connected on the lower surface of the material plate along the length of the material plate, and the mounting blocks are connected to the pusher blocks in the sliding groove.

[0011] A further configuration is provided: a material distribution plate is installed at the end of the pusher block away from the material trough, and the radial distance between the lower surface of the material distribution plate and the pusher block is equal to the thickness of the product body.

[0012] The present invention has the following beneficial effects:

[0013] 1. This invention is mainly aimed at the feeding action in the processing of small products. Taking injection molded products as an example, two stacking plates form a stacking groove to stack the products. Each stacking groove corresponds to a single sliding groove. When the pusher block moves horizontally, it can push a single product in the stacking groove from the stacking groove to the material groove. At the same time as picking up the material, the pusher block is also used to complete the clamping action of the product, so as to cooperate with the robotic arm to perform negative pressure adsorption and gripping of the corresponding product.

[0014] 2. When the pusher block performs pushing, clamping, and positioning actions on the product, by limiting the thickness of the pusher block to be equal to the thickness of the product, the pusher block can only operate on one product at a time. In addition, a material distribution plate is added to the pusher block. The material distribution plate does not affect the product pushing process, and the radial distance between the lower surface of the material distribution plate and the pusher block is further limited to be equal to the thickness of the product body. Thus, when pushing the product, the material distribution plate is also used to "support" the product in the upper position, which can prevent the product in the upper position from being misaligned or leaking.

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] For the feeding process of small-volume products, manual feeding is inefficient and cannot meet the requirements of high-efficiency production. If mechanical feeding is used, on the one hand, due to the small size, it is difficult to accurately locate the gripping point of the injection molded product; on the other hand, it is also necessary to meet the production requirement of rapid gripping. Therefore, the following technical solution is proposed:

[0026] Reference Figures 1-6The bidirectional automatic feeding mechanism with positioning function in this embodiment includes a base frame 1 and a robotic arm 2. The robotic arm 2 is mounted on the base frame 1. A material stacking structure is provided on one side of the base frame 1. The material stacking structure includes a material plate 4, multiple material stacking slots 3, and a mounting plate 5. The material plate 4 is connected to the base frame 1. The multiple material stacking slots 3 are perpendicular to the upper surface of the material plate 4. The mounting plate 5 is mounted at the moving end of the robotic arm 2. Sliding grooves 12 are provided at the four corners of the upper surface of the material plate 4, and adjusting blocks 9 are installed on both sides of the material plate 4 corresponding to the sliding grooves 12. The material stacking slots 3 are mounted on the adjusting blocks 9 in a vertically upward direction and slide along the sliding grooves. A material stacking groove is formed between two material stacking plates 3 in the width direction of 12, and a pusher block 10 is slidably installed in the material stacking groove 12 along the length direction of the material plate 4. A corresponding drive structure for the pusher block 10 is provided on the lower side of the material plate 4. A suction nozzle assembly is provided on the mounting plate 5. A material groove 11 is provided between the inner wall of the pusher block 10 and the pusher block 10. The diameter of the material groove 11 is equal to the diameter of the material stacking groove. Multiple product bodies are stacked in the material stacking groove in the vertical direction. The suction nozzle assembly consists of four negative pressure air nozzle suction cups 8. The four negative pressure air nozzle suction cups 8 are installed in the mounting plate 5, and the installation positions of the four negative pressure air nozzle suction cups 8 correspond to the setting of the material groove 11.

[0027] Operating principle: First, it needs to be explained that the material stacking structure is assembled according to the corresponding product volume. Specifically, a sliding groove 12 corresponding to the size of the product is opened on the material plate 4. Then, a corresponding number of adjusting blocks 9 and stacking groove plates 3 are installed according to the size of the sliding groove 12, so that a stacking groove is formed between the stacking groove plates 3 of the corresponding sliding groove 12. The corresponding stacking groove is used to stack and place products. Therefore, the diameter of the stacking groove corresponds to the size of the product. Then, the robotic arm 2, the base plate frame 1 and the material plate 4 are finally assembled. The selection of the robotic arm 2 and the negative pressure air nozzle suction cup 8 will not be described here.

[0028] During the overall structural operation, under the action of gravity, the products in the stacking trough accumulate downwards. Then, when the feeding action begins, the two mounting blocks 6 are driven to move in opposite directions by the bidirectional cylinder 7, which in turn drives the pusher block 10 to move towards the trough 11, as shown above. Under the action of gravity, the bottom layer of products in the stacking trough falls into the sliding trough 12. Therefore, under the pushing action of the pusher block 10, the products that have fallen into the sliding trough 12 can be squeezed into the trough 11. In this process, not only is the feeding process of a single product completed, but the pusher block 10 also simultaneously completes the positioning of the product, so that the product is directly squeezed into the trough 11. Finally, the robotic arm 2 drives the mounting plate 5 to move in a direction, and the negative pressure air nozzle suction cup 8 adsorbs the product in the trough 11, thereby completing the product clamping action.

[0029] Example 2

[0030] This embodiment is a further optimization and improvement of the pusher block in Embodiment 1:

[0031] The thickness of the product body, the thickness of the pusher block 10, the depth of the sliding groove 12, and the distance between the lower surface of the adjusting block 9 and the bottom of the inner wall of the sliding groove 12 are equal. The driving structure includes a bidirectional cylinder 7 and two mounting blocks 6. The bidirectional cylinder 7 is installed at the center point of the lower surface of the material plate 4. The mounting blocks 6 are arranged in a mirror symmetrical manner along the installation position of the bidirectional cylinder 7. The transmission rod of the bidirectional cylinder 7 is connected to the mounting blocks 6. The mounting blocks 6 are slidably connected to the lower surface of the material plate 4 along the length direction of the material plate 4. The mounting blocks 6 are connected to the pusher block 10 in the sliding groove 12. A material distribution plate 13 is installed at the end of the pusher block 10 away from the material groove 11. The radial distance between the lower surface of the material distribution plate 13 and the pusher block 10 is equal to the thickness of the product body.

[0032] Operating principle: As described in Example 1, the pusher block 10 pushes a single product. To achieve this, a distribution plate 13 is added to the pusher block 10. The distribution plate 13 is restricted to the radial distance between its lower surface and the pusher block 10, which is equal to the thickness of the product body. The purpose of this restriction is that when the pusher block 10 completes the pushing action of the bottom layer of the stacking groove, the distribution plate 13 moves synchronously with the pusher block 10 into the stacking groove, thus isolating other products in the stacking groove and providing "lower support" for other products. This can prevent misalignment and leakage of products in the upper position.

[0033] In summary: For the feeding process of smaller products, a combination of stacking and bidirectional pushing is used to complete the product positioning and clamping actions. Then, a robotic arm is used to perform the product adsorption and gripping action. Specifically, a bidirectional pushing method with top feeding and bottom output is adopted. When the pushing block pushes a single product, the product positioning action is completed simultaneously, so that the robotic arm can perform the product adsorption and gripping action. Moreover, when the pushing block is pushing, it will not affect the product position inside the stacking slot, and it can avoid the problems of misalignment and leakage of products in the upper position.
