Description

Technical Field

[0001] This utility model relates to the technical field of neodymium iron boron presses, and in particular to a material conveying mechanism. Background Technology

[0002] This material handling mechanism is located between the press and the stacking machine, used to transfer the workpieces formed in the press to the stacking machine. In existing technology, the material handling mechanism uses an integrated track and a rodless cylinder as the power source. One end of the integrated track extends into the press, and the other end extends into the stacking machine. Since the press needs to change the forming mold when pressing workpieces of different specifications, the integrated track interferes with the disassembly and assembly of the forming mold. Therefore, when changing the forming mold, it is necessary to first remove the integrated track and the rodless cylinder mounted on it. After the forming mold is replaced, the track and the rodless cylinder are then reinstalled, resulting in time-consuming, labor-intensive, and inefficient operation. Utility Model Content

[0003] The purpose of this invention is to provide a material conveying mechanism. This application adopts a split-type track design and is equipped with a motor as the power source. The split-type track consists of a first track and a second track, which are connected by a connector to form a linear track. The drive unit drives the receiving seat to move along the linear track via a transmission belt to realize material conveying. When it is necessary to change the molding die, simply disconnect the receiving seat from the second end of the transmission belt, thereby eliminating the influence of the transmission belt on folding the second track. Then, unlock the connector to fold the second track, making room for the mold change. This split-type track design is simple to operate and highly efficient.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a material conveying mechanism, including a support, a first track, a second track, a receiving seat, a connecting member, and a conveying mechanism disposed on the first track and the second track. The first track is fixedly disposed on the support, and the adjacent ends of the first track and the second track are hinged together.

[0005] Furthermore, the connector is located at the adjacent ends of the first track and the second track. When the connector is locked, the first track and the second track form a linear track. When the connector is disassembled, the second track can rotate about the hinge end as the axis of rotation, thereby making room for changing the mold.

[0006] Furthermore, the second end of the transmission belt is connected to a fixing block A, and the receiving seat is provided with a mounting groove for mounting the fixing block A. The receiving seat is provided with a locking mechanism for detachably fixing the fixing block A in the mounting groove. The installation and removal of the fixing block A can be switched by operating the locking mechanism.

[0007] Furthermore, the receiving seat is provided with a slot that connects to the mounting groove. The locking mechanism includes a pin, a spring, and a limiting block. The pin is telescopically disposed in the slot. The spring is fitted around the outer periphery of the pin. The limiting block is installed at the open end of the slot. The inner end of the slot is provided with an abutment portion. The spring abuts between the abutment portion and the limiting block. The fixing block A is provided with a positioning hole. The pin is inserted into the positioning hole under the elastic force of the spring and is positioned and engaged with the positioning hole.

[0008] Furthermore, a fixing block B is fixedly connected to the first end of the transmission belt, and the fixing block B is fixedly connected to the receiving seat.

[0009] Furthermore, the receiving seat is provided with at least one placement platform, and each placement platform is equipped with a weighing sensor at its lower end.

[0010] Furthermore, the receiving seat is provided with guide wheels that cooperate with the linear track guide.

[0011] Furthermore, the connector is a fastener, and the first track and the second track are fitted together to form mounting holes that match the fastener. The first track and the second track are fixedly connected by the fastener fitting into the mounting holes.

[0012] Furthermore, drag chains are also provided on the sides of the first and second tracks.

[0013] In summary, this utility model has the following beneficial effects: 1. The material conveying mechanism of this utility model adopts a split track design and is equipped with a motor as a power source. The split track consists of a first track and a second track, which are connected by a connector to form a linear track.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1-4As shown, a material conveying mechanism includes a support 10, a first track 20, a second track 30, a receiving seat 40, a connecting member 50, and a conveying mechanism 60 disposed on the first track 20 and the second track 30. The first track 20 is fixedly disposed on the support 10, and the adjacent ends of the first track 20 and the second track 30 are hinged together. Specifically, the first track 20 and the second track 30 are hinged together by a pin 70. The connecting member 50 is used to fix the adjacent ends of the first track 20 and the second track 30 together so that the first track 20 and the second track 30 form a linear track. The receiving seat 40 is slidably mounted on the linear track. The conveying mechanism 60 includes a first drive wheel 61 located at the outer end of the first track 20, a second drive wheel 62 located at the outer end of the second track 30, a drive belt 63 wound around the first drive wheel 61 and the second drive wheel 62, and a drive unit 64 that drives the first drive wheel 61 to rotate. The drive unit 64 is preferably a servo motor. The drive belt 63 is an open-type drive belt 63. The first end of the drive belt 63 is fixedly connected to the receiving seat 40, and the second end of the drive belt 63 is detachably fixedly connected to the receiving seat 40.

[0021] When the hinge end is located at the lower end of the first track 20 and the second track 30, the second track 30 can rotate downward about the hinge end as the axis of rotation to make room for changing the mold; when the hinge end is located at the upper end of the first track 20 and the second track 30, the second track 30 can rotate upward about the hinge end as the axis of rotation to make room for changing the mold.

[0022] The material conveying mechanism is fixed between the press and the stacking machine by the bracket 10. In this application, the linear track formed by the first track 20 and the second track 30 is set in an inclined shape, specifically, the side adjacent to the press is higher and the side adjacent to the stacking machine is lower. Of course, as an equivalent alternative, the linear track formed by the first track and the second track 30 can also be set horizontally.

[0023] The material conveying mechanism of this utility model adopts a split track design and is equipped with a motor as the power source. The split track consists of a first track 20 and a second track 30, which are connected by a connector 50 to form a linear track. The drive unit 64 drives the receiving seat 40 to move along the linear track through the transmission belt 63 to realize material conveying. When it is necessary to change the molding die, simply disconnect the receiving seat 40 from the second end of the transmission belt 63 to eliminate the influence of the transmission belt 63 on folding the second track 30. Then, unlock the connector 50 to fold the second track 30, making room for the mold change. This split track design is simple to operate and highly efficient.

[0024] In some embodiments, the connector 50 is disposed at the adjacent ends of the first track 20 and the second track 30. When the connector 50 is locked, the first track 20 and the second track 30 form a linear track. When the connector 50 is disassembled, the second track 30 can rotate about the hinge end as the axis of rotation to make room for changing the mold.

[0025] In some embodiments, the second end of the transmission belt 63 is connected to a fixing block A65, and the receiving seat 40 is provided with a mounting groove 43 for mounting the fixing block A65. The receiving seat 40 is provided with a locking mechanism 80 for detachably fixing the fixing block A65 in the mounting groove 43. The installation and removal of the fixing block A65 can be switched by operating the locking mechanism 80. The width of the mounting groove 43 is adapted to the width of the fixing block A65.

[0026] In some embodiments, the receiving seat 40 is provided with a slot 41 communicating with the mounting groove 43. The locking mechanism 80 includes a pin 81, a spring 82, and a limiting block 83. The pin 81 is telescopically disposed in the slot 41. The spring 82 is fitted around the outer periphery of the pin 81. The limiting block 83 is installed at the open end of the slot 41. The inner end of the slot 41 is provided with an abutment portion. The spring 82 abuts against the abutment portion and the limiting block 83. The fixing block A65 is provided with a positioning hole 651. The pin 81 is inserted into the positioning hole 651 under the elastic force of the spring 82 and is positioned and engaged with the positioning hole 651. By pulling the pin 81 outward, the positioning engagement between the pin 81 and the positioning hole 651 is released, thereby removing the fixing block A65 from the receiving seat 40. Under normal conditions, the pin 81 tends to remain inserted into the positioning hole 651 under the elastic force of the spring 82.

[0027] In some embodiments, a fixing block B66 is fixedly connected to the first end of the transmission belt 63. The fixing block B66 is fixedly connected to the receiving seat 40. For example, the fixing block B66 is fixedly connected to the receiving seat 40 by screws. That is to say, whether the material conveying mechanism is working normally or in the mold folding state, the fixing block B66 and the receiving seat 40 remain fixedly connected.

[0028] In some embodiments, the receiving seat 40 is provided with at least one placement platform, and each placement platform is equipped with a weighing sensor at its lower end. The weighing sensor is used to weigh the workpiece on the placement platform. During the process of the workpiece being gripped by the robot after being pressed and placed on the placement platform, there may be a problem of it being crushed. The weighing sensor can weigh the workpiece placed on the placement platform to determine whether the quality of the workpiece meets the requirements, thereby indirectly verifying whether the workpiece has been crushed at this time.

[0029] In some embodiments, the receiving seat 40 is provided with guide wheels 42 that cooperate with the linear track. Specifically, multiple sets of guide wheels 42 are provided on both sides of the receiving seat 40, and guide strips that cooperate with the guide wheels 42 are provided on the side end of the linear track. This arrangement can improve the stability and smoothness of the receiving seat 40 when it moves.

[0030] In some embodiments, the connector 50 is a fastener, and the first track 20 and the second track 30 are fitted together to form mounting holes that match the fastener. The first track 20 and the second track 30 are fixedly connected by the fastener and the mounting holes. Specifically, in order to make the connection between the first track 20 and the second track 30 more secure, two sets of mounting holes are provided and staggered, and each mounting hole is equipped with a connector 50.

[0031] In some embodiments, the first track 20 and the second track 30 are further provided with drag chains 90, which are used to place pipelines.

[0032] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
