Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of machining, specifically relates to a swing arm type material taking and placing mechanism. BACKGROUND

[0002] At present, for the transfer of some materials, it needs to meet the motion requirements of multiple degrees of freedom, for example: rotation, lifting, however, in the conventional operation, the motion between two degrees of freedom cannot be synchronized, therefore, in the process of taking and placing materials, the following technical defects exist:

[0003] 1) the degrees of freedom cannot cooperate, therefore, only single and sequential motion mode can be used to take and place materials, resulting in low efficiency and high cost of taking and placing materials;

[0004] 2) the required structure is more complex, and enough installation space is needed, resulting in large volume, which cannot be applied to various limited spaces. UTILITY MODEL CONTENT

[0005] The utility model aims at overcoming the defects of the prior art, and provides an improved swing arm type material taking and placing mechanism.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following scheme:

[0007] A swing arm type material taking and placing mechanism, which comprises a base, a material taking swing arm, a rotating power unit for driving the material taking swing arm to rotate horizontally around the connecting end portion, and a lifting power unit for driving the material taking swing arm to lift up and down, in particular,

[0008] The rotating power unit comprises a power device mounted on the base and arranged on the power shaft in the up-down direction, and a power seat capable of moving in the up-down direction and synchronously rotating with the power shaft, and the material taking swing arm is fixed to the power seat at one end portion;

[0009] The lifting power unit comprises a displacement seat sliding on the base in the up-down direction, and a driver for driving the displacement seat to reciprocate up and down, wherein the power seat is mounted on the displacement seat and can rotate freely at the lower end portion, the power seat can reciprocate up and down synchronously with the displacement seat, and the power seat can also rotate synchronously with the power shaft.

[0010] Preferably, one of the power shaft and the power seat is provided with a matching mold strip extending in the up-down direction, and the other is provided with a matching groove matched with the matching mold strip, wherein the lifting reciprocating motion is based on the movement of the matching mold strip in the matching groove. Here, the matching connection not only forms the required linear motion guide, but also increases the synchronization degree of the rotation of the power shaft and the power seat.

[0011] Further, matching die strips extending upward and downward are arranged on the opposite sides of the power shaft, and matching grooves are correspondingly arranged on the power seat.

[0012] According to one specific implementation and preferred aspect of the present application, the power seat comprises a seat body in the shape of a rectangular body, a die seat having a matching groove and being mounted inside the seat body, wherein the seat body is pivotally mounted on the displacement seat from the bottom, the power shaft is inserted into the matching groove of the die seat from the matching die strip, and the length of the matching die strip is greater than the length of the die seat. Based on the arrangement of the die seat, upward and downward movement guidance is facilitated between the two, and the corresponding length setting reduces the relative displacement rate. In addition, the design of the rectangular body is mainly convenient for disassembling the material taking swing arm.

[0013] In some specific implementations, the displacement seat is in the shape of L, wherein the displacement seat is mounted on the stand from the vertical part of the L-shaped part in upward and downward movement, and the power seat is pivotally mounted on the horizontal part of the L-shaped part.

[0014] Preferably, a slide rail extending upward and downward is arranged on the stand, and the displacement seat is matched with the slide rail. Based on the slide rail forming movement guidance, the movement stability control is more beneficial.

[0015] According to another specific implementation and preferred aspect of the present application, the driver comprises a driving motor horizontally arranged on the driving shaft, and a transmission member for drivingly connecting the driving shaft and the displacement seat, wherein the transmission member is an eccentric connecting rod member. The upward and downward reciprocating movement is realized by using the eccentric connecting rod member, and the installation space is small, and the driver and the power device are vertically arranged.

[0016] Preferably, the eccentric connecting rod member comprises an eccentric wheel mounted on the end of the driving shaft, a connecting column fixedly arranged on the displacement seat, and an eccentric connecting rod for connecting the eccentric wheel and the connecting column.

[0017] Further, a tension spring for keeping the displacement seat upward is arranged between the stand and the displacement seat. Based on the tension spring keeping the upward positioning, the eccentric connecting rod is kept in the stressed state when not working.

[0018] Specifically, the tension spring has a plurality of tension springs, and each tension spring is located on the opposite sides of the top of the displacement seat.

[0019] Due to the use of the above technical and equipment scheme, the present application has the following advantages compared with the prior art:

[0020] In the existing material transfer, the degrees of freedom cannot cooperate with each other, so that the material taking and placing can only be completed in a single and sequential manner, resulting in low efficiency and high cost of material taking and placing; meanwhile, the required structure is more complex and requires sufficient installation space, resulting in large size and inability to be applied to various limited spaces and the like. The present application designs the swing arm type material taking and placing mechanism as a whole, ingeniously solves the deficiencies and defects of the prior art, and after the swing arm type material taking and placing mechanism is adopted, the material taking swing arm is fixed at one end of the power seat, then the power seat can move synchronously up and down with the displacement seat, and the power seat can also rotate synchronously with the power shaft, so that the rotation and reciprocating lifting can be synchronously implemented, or can be implemented alone to complete the material taking and placing operation of the material taking swing arm. Therefore, the present application can effectively combine the rotation and reciprocating lifting of the material taking swing arm, not only can be implemented synchronously, but also can be implemented alone to meet different material taking requirements, and the efficiency of material taking and placing is high and the cost is low; on the other hand, the overall structure is optimized, not only the overall size is reduced, but also the performance accumulation can improve the stability and practicability of operation.

[0035] like Figures 1 to 4 As shown, the swing arm type material handling mechanism of this embodiment includes a base 1, a material handling swing arm 2, a rotation power unit 3 that drives the material handling swing arm 2 to rotate horizontally around the connecting end, and a lifting power unit 4 that drives the material handling swing arm 2 to move up and down.

[0036] Specifically, the rotational power unit 3 includes a power unit 30 mounted on the base 1 and vertically arranged on the power shaft 300, and a power seat 31 that moves relative to the power shaft 300 in the vertical direction and can rotate synchronously with the power shaft 300. The material handling arm 2 is fixed to the power seat 31 from one end. The lifting power unit 4 includes a shift seat 40 that slides along the vertical direction on the base 1, and a driver 41 that drives the shift seat 40 to reciprocate vertically. The power seat 31 is rotatably mounted on the shift seat 40 from its lower end. The power seat 31 can reciprocate vertically synchronously with the movement of the shift seat 40, and the power seat 31 can also rotate synchronously with the rotation of the power shaft 300.

Here, the matching connection not only forms the required linear motion guide, but also increases the synchronization of the rotation of the power shaft and the power base. In this example, the matching mold strips m extend upward and downward on opposite sides of the power shaft 300, and the matching grooves q are correspondingly provided on the power base 31. Not only is it convenient to operate, but it also increases the service life. The power base 31 includes a rectangular body-shaped base body 310 and a mold seat 311 mounted inside the base body 310 and having a matching groove q, wherein the base body 310 is pivotally mounted to the displacement seat 40 from the bottom, the power shaft 300 is inserted into the matching groove q of the mold seat 311 from the matching mold strip m, and the length of the matching mold strip m is greater than the length of the mold seat 311. Based on the arrangement of the mold seat, it is convenient to form the upward and downward motion guide between the two, and the corresponding length setting reduces the relative displacement rate. In addition, the rectangular body design is mainly convenient for disassembling and assembling the material taking swing arm.

[0038] In some embodiments, the displacement seat 40 is L-shaped, wherein the vertical part of the L-shaped part is movably installed on the instrument seat 1, and the power base 31 is rotatably installed on the horizontal part of the L-shaped part. The instrument seat 1 is provided with a slide rail 10 extending upward and downward, and the displacement seat 40 is matched with the slide rail 10. The slide rail forms a motion guide, which is more conducive to motion stability control. The driver 41 includes a drive shaft a horizontally arranged drive motor 410 and a transmission member 411 for drivingly connecting the drive shaft a and the displacement seat 40, wherein the transmission member 411 is an eccentric connecting rod member.

The eccentric connecting rod member includes an eccentric wheel b mounted on the end of the drive shaft, a connecting column c fixedly arranged on the displacement seat 40, and an eccentric connecting rod d for connecting the eccentric wheel b and the connecting column c.

[0039] In addition, a tension spring 5 is arranged between the instrument seat 1 and the displacement seat 40 for keeping the displacement seat 40 upwardly pulled. Based on the upward pulling positioning of the tension spring 5, the eccentric connecting rod is kept in a stressed state when not working. The tension spring 5 has a plurality of tension springs 5, and each tension spring 5 is located on opposite sides of the top of the displacement seat 40 (in this example, the tension spring 5 has two tension springs).

Therefore, the utility model can effectively combine the rotation and the reciprocating lifting of the material taking swing arm, not only can be synchronous, but also can be implemented independently to meet the different material taking requirements, and the efficiency of the material taking and placing is high and the cost is low. On the other hand, the overall structure is optimized, not only the overall volume is reduced, but also the running stability and practicability can be improved based on the performance accumulation. Thirdly, the matching mode strips extending upward and downward are arranged on the opposite sides of the power shaft, and the matching grooves are correspondingly arranged on the power seat, not only the operation is convenient, but also the service life is increased, the matching and docking not only form the required linear motion guide, but also increase the synchronous degree of the rotation of the power shaft and the power seat. Fourthly, based on the arrangement of the mode seat, the upward and downward motion guide between the two is formed, and the corresponding length is set to reduce the relative displacement rate. In addition, the rectangular body is adopted for the design, which is mainly convenient for the disassembly and assembly of the material taking swing arm.
