Description

Technical Field

[0001] This invention relates to the field of product dispensing devices, and more specifically, to a dispensing mechanism. Background Technology

[0002] Currently, the assembly of various products, whether as a whole or as a component, is increasingly adopting automated assembly to save manpower, reduce costs, and improve assembly efficiency. Automated assembly first requires the parts to be sorted, and then gripped by a gripping device before assembly. Taking a product requiring compatibility with or having two different push rods as an example, the push rods first need to be sorted, meaning individual push rods are separated and transported to a gripping station, where they are then gripped by a gripping device (such as a robotic arm). The two types of push rods are typically sorted by their own independent sorting mechanisms and gripped by their own separate gripping devices. However, for products assembling these two types of push rods, since the two types often cannot be assembled simultaneously, the two gripping devices need to alternate waiting. Compared to a single gripping device, this does not improve assembly efficiency, but rather wastes resources and increases costs due to the additional sorting mechanism and gripping device. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a material dispensing mechanism to solve the above problems.

[0004] The present invention adopts the following solution:

[0005] This application provides a material distribution mechanism for distributing two types of products with holes. It includes a base and a driving component disposed on the base, as well as a push rod material distribution block disposed on the base, two positioning components, and a trajectory plate.

[0006] The base is provided with a sliding groove along a first direction, and two first feeding grooves suitable for the product are provided along a second direction, as well as a distributing station located between the two feeding grooves; the push rod distributing block is provided with two second feeding grooves adapted to the first feeding grooves; the push rod distributing block can move back and forth on the sliding groove with the product under the drive of the driving member, so that the product placed on the two second feeding grooves can be sequentially transferred to the distributing station; the track plate is provided with a track groove; the positioning member can move back and forth on the track groove under the drive of the push rod distributing block, and move back and forth in the vertical direction under the action of the track groove; the track groove is configured to enable the positioning member to position the hole position during the process of the product moving from the second feeding groove to the distributing station.

[0007] Furthermore, it also includes a detection device disposed above the first feeding trough and the second feeding trough, used to detect whether the product is fed in place.

[0008] Furthermore, the trajectory groove has a gradually transitioning high position in the middle and low positions on both sides; when one end of one of the positioning members moves from the low position to the high position along the trajectory groove, its other end extends into the second feeding groove and is inserted into the hole of the product; while one end of the other positioning member moves from the high position to the low position along the trajectory groove, its other end retracts and exits from the second feeding groove.

[0009] Furthermore, the low positions on both sides are symmetrically arranged, and the transition between the low positions and the high positions is achieved through an inclined surface.

[0010] Furthermore, it also includes a guide block connected below the push rod material distribution block, the guide block being provided with a guide groove corresponding to the second feeding groove; a pull rod is slidably provided on the guide groove, the upper end of the pull rod being provided with a positioning pin, the lower end being provided in the trajectory groove, and being able to move along the trajectory groove.

[0011] Furthermore, the lower end of the pull rod is rotatably connected to a rotating component.

[0012] Furthermore, the rotating component is a rolling bearing.

[0013] Furthermore, it also includes a gripping device for gripping the product placed on the sorting station.

[0014] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0015] This invention provides a material distribution mechanism, which has a sliding groove on a base along a first direction, two first feeding slots suitable for products along a second direction, and a material distribution station placed between the two feeding slots. A driving component drives a push rod material distribution block to reciprocate on the sliding groove, so that the two second feeding slots on the push rod material distribution block alternately place products at the material distribution station, realizing the alternating distribution of two types of products. At the same time, the setting of the track plate and the track groove allows the positioning component to reciprocate on the track groove under the drive of the push rod material distribution block, and to reciprocate in the vertical direction under the action of the track groove. This enables the positioning component to position the holes of the product during the process of the product moving from the second feeding slot to the material distribution station, further realizing the limiting of the product, so that the product is grasped by the gripping device in the correct posture and then distributed, thereby realizing alternating assembly.

[0023] Example

[0024] Combination Figures 1 to 4As shown, this embodiment provides a material distribution mechanism for distributing two types of products with holes. Specifically, the material distribution mechanism includes a base 1 and a drive member 10 disposed on the base 1, as well as a push rod material distribution block 9 disposed on the base 1, two positioning members, and a trajectory plate 12.

[0025] Specifically, in this embodiment, the base 1 is mounted on the support 2. The base 1 has a sliding groove 3 along a first direction, two first feeding grooves suitable for the product along a second direction, and a material distribution station 8 located between the two feeding grooves. The push rod material distribution block 9 has two second feeding grooves adapted to the first feeding grooves. Driven by the drive member 10, the push rod material distribution block 9 can reciprocate along the sliding groove 3 with the product, so that the product placed on the two second feeding grooves can be sequentially transferred to the material distribution station 8. The following example uses two first feeding grooves as a left first feeding groove 4 and a right first feeding groove 5, and two second feeding grooves as a left second feeding groove 6 and a right second feeding groove 7. In the initial state, the left second feeding groove 6 is in a position corresponding to the left first feeding groove 4, at which time the first type of product can be fed from the left first feeding groove 4 into the left second feeding groove 6; while the right second feeding groove 7 is in the material distribution station 8. In this embodiment, taking the driving component 10 as a cylinder as an example, it is connected to the push rod distributing block 9 via a coupling 20. When the cylinder pushes the push rod distributing block 9 to the right, the right second feeding trough 7 moves to the right to a position corresponding to the right first feeding trough 5. At this time, the second type of product can be fed from the right first feeding trough 5 into the right second feeding trough 7; while the left second distributing trough moves to the right to the middle distributing station 8 for distributing. Then, driven by the cylinder, the push rod distributing block 9 reciprocates, realizing the alternating feeding and distributing of the left second feeding trough 6 and the right second feeding trough 7.

[0026] In this embodiment, a detection device 11 is also provided above the left first feeding trough 4 and the right first feeding trough 5 to detect whether the product is fed in place; when the detection device 11 detects that the product is fed in place, it starts the cylinder to drive the push rod material distribution block 9 to move back and forth.

[0027] In this embodiment, the track plate 12 is fixedly mounted below the base 1, and a track groove 13 is provided on it. The material distribution mechanism also includes a guide block 14 connected below the push rod material distribution block 9. The guide block 14 is provided with a left guide groove and a right guide groove corresponding to the second feeding groove. A left pull rod 15 and a right pull rod 16 are slidably disposed on the guide grooves, respectively. A positioning pin is provided at the upper end of the pull rod, and a rolling bearing 19 is provided at the lower end, which is placed in the track groove 13 and can move along the track groove 13. It can be understood that when the cylinder drives the push rod material distribution block 9 to move, it simultaneously drives the guide block 14 and the pull rod to move, while the rolling bearing 19 rolls in the track groove 13.

[0028] The trajectory groove 13 has a gradually transitioning central high position and left and right low positions on both sides; specifically, the low positions on both sides are symmetrically arranged, and the transition between the low position and the high position is achieved through an inclined surface. In the initial state, the rolling bearing 19 of the left pull rod 15 is placed on the left low position, at which time the left positioning pin 17 at the upper end of the left pull rod 15 is below the left second feeding groove 6; while the rolling bearing 19 of the right pull rod 16 is placed on the high position, at which time the right positioning pin 18 at the upper end of the right pull rod 16 is in the right second feeding groove 7. When the push rod distributing block 9 moves to the right, the rolling bearing 19 of the left pull rod 15 moves to the high position along the track groove 13. At this time, the left positioning pin 17 at the upper end of the left pull rod 15 moves upward into the left second feeding groove 6. Simultaneously, the rolling bearing 19 of the right pull rod 16 moves to the right low position along the track groove 13. At this time, the right positioning pin 18 at the upper end of the right pull rod 16 retracts below the right second feeding groove 7. In this embodiment, the transition between the low position and the high position is achieved through an inclined surface. When the cylinder drives the push rod distributing block 9 to move to the right, and the rolling bearing 19 of the left pull rod 15 moves from the left low position to the high position, the left positioning pin 17 immediately begins to move upward, enters the second feeding groove, and inserts into the hole of the product to limit the product and ensure that the product is distributed in the correct posture. Simultaneously, as the rolling bearing 19 moves from a high position to a lower right position, the right positioning pin 18 immediately begins to retract. When the rolling bearing 19 is positioned at the lower right position, the right positioning pin 18 retracts to below the right second feeding groove 7, at which point feeding can continue. When the cylinder drives the push rod separating block 9 to move to the left, the situation is exactly the opposite; that is, the left positioning pin 17 and the right positioning pin 18, under the action of the track groove 13, achieve alternating up and down movement.

[0029] In this embodiment, a gripping device may also be included to grip the product placed on the material sorting station 8, so as to facilitate the next step of assembly. Of course, the gripping device may be a robotic arm, which will not be specifically described here.

[0030] This material distribution mechanism enables alternating material distribution for two different products. Its simple overall structure ensures efficiency while minimizing the number of components and reducing costs. The track plate 12 and track groove 13 allow the positioning component to reciprocate along the track groove 13 under the influence of the push rod material distribution block 9, and also reciprocate vertically under the action of the track groove 13. This enables the positioning component to locate the product's holes as the product moves from the second loading slot to the material distribution station 8, further limiting the product's position and ensuring it is correctly gripped by the gripping device for material distribution, thus achieving alternating assembly.
