Description

Technical field

Background technique

At present, domestic refrigerators are all horizontally foamed and transmitted. Therefore, in the refrigerator assembly line, it is inevitable to convert the foamed box from horizontal to upright, and place a foam base under the box. Most of the existing production lines require manual work to straighten the box and manually select the appropriate type of base to place under the box. The process is cumbersome, and turning the box over can easily cause bumps and scratches, which consumes manpower and time, resulting in low production efficiency and poor product quality. There are many problems such as uncontrollable quality. Moreover, the bases of different models of refrigerators are often not universal, and the bases need to be placed separately, which increases the process.

In order to solve the above problems, an automatic base-mounting device has been designed in the prior art. It first lifts the box through a box positioning mechanism, then flips the box 90 degrees through a vertical box transfer machine, and finally turns the box over 90 degrees. Place the box on the positioned base. However, the vertical box transfer machine of this equipment needs to be equipped with a lifting trolley and a horizontal moving trolley, and corresponding motion tracks must be set up for the lifting trolley and horizontal moving trolley. As a result, the vertical box transfer machine is larger in size, takes up more space, and The structure is very complex. Moreover, the box completes the transformation from horizontal to upright inside the vertical box transfer machine. During the flipping process, the box body can easily interfere or collide with the internal structure of the vertical box transfer machine, and the box body can easily be damaged. Finally, the vertical box transfer machine can only translate the box in a fixed direction, so the base needs to be moved from the base moving device to the base positioning device to place the box on the base. The base positioning device has a complex structure and unreliable positioning.

Detailed ways

The invention provides an automatic base assembly device for a refrigerator, which is used for assembling the base to a box body of the refrigerator. Figures 1 and 2 are schematic structural diagrams of the base automatic assembly equipment in different directions according to an embodiment of the present invention. For ease of understanding, Figures 1 and 2 also show the refrigerator box 2 and multiple bases 3 . Referring to Figures 1 and 2, the automatic base assembly equipment 1 of the present invention includes a box conveying mechanism 10, a base conveying mechanism 20, an identification device 30, an automatic upper base structure 40 and a robotic arm structure 50.

The box conveying mechanism 10 is used to carry the box 2 and drive the box 2 to move. The base transmission mechanism 20 is used to carry the base 3 and drive the base 3 to move. The identification device 30 is used to obtain the parameter information of the box 2 on the box conveying mechanism 10 to identify the model of the box 2 . The automatic base loading structure 40 is configured to automatically select a matching base 3 according to the model of the box 2 recognized by the identification device 30 and output it to the base transfer mechanism 20 . The robotic arm structure 50 is used to adjust the box 2 on the box conveying mechanism 10 to an upright position, and place the box 2 in the upright position on the base 3 .

The automatic base assembly equipment 1 of the present invention transports the foamed box 2 and the base 3 matching the box 2 through the box conveying mechanism 10 and the base conveying mechanism 20 respectively, and automatically identifies the model of the box 2 through the identification device 30 , the automatic upper base structure 40 automatically selects the base 3 that matches the model of the box 2 and outputs it to the base transfer mechanism 20, and the robotic arm structure 50 adjusts the box 2 on the box transfer mechanism 10 to an upright posture. , and places the box 2 in an upright position on the base 3, realizing automatic assembly between the box 2 and the base 3. It is highly intelligent and does not require manual flipping of the box or manual screening of the base and base. Installing the base saves manpower and improves assembly efficiency.

Moreover, the robotic arm structure 50 of the present invention is very similar to an artificial arm, and has a relatively high degree of mechanization, integration, and intelligence. Therefore, its structure is relatively simple and takes up less space. In terms of location and space, the robotic arm structure 50 only needs to be placed beside the box conveying mechanism 10 and will not occupy the space above the box conveying mechanism 10; in terms of functional realization, the robotic arm structure 50 only needs to clamp The box 2 is placed on the box conveying mechanism 10, and its own structure can be used to realize the flipping and movement of the box 2 in multiple directions. The turning space and moving space of the box 2 will not interfere with the machinery located next to it. The arm structure 50 interferes or collides, which reduces the possibility of damage to the box 2 during the base assembly process.

Specifically, the identification device 30 can be located next to the transmission path of the box conveying mechanism 10, and in the conveying direction of the box conveying mechanism 10, the identification device 30 is located on the upstream side of the robotic arm structure 50, so as to facilitate the identification of the boxes. 2. Identify the type of box 2 before reaching the robotic arm structure 50, thereby facilitating the automatic upper base structure 40 to select a matching base 3 in advance, thereby reducing the time consumed in base assembly.

In some embodiments, the base automatic assembly equipment 1 also includes a first limiting structure 60 , which is configured to adjust when the box 2 is driven by the box conveying mechanism 10 to move to a preset box state. The first indication signal is generated at the station, and the first indication signal is used to prompt the box conveying mechanism 10 to stop running, so that the box 2 can rest at the box state adjustment station.

Further, the robotic arm structure 50 is configured to controllably adjust the box 2 to an upright posture after the box 2 rests at the box state adjustment station. That is to say, when the box 2 is still at the preset box state adjustment station, the robotic arm structure 50 starts to adjust the state of the box 2, so that the robotic arm structure 50 can accurately find the position of the box 2, and then Clamp and turn box 2 securely.

Specifically, the first limiting structure 60 can be a limit sensor, which can detect whether the box 2 is in the box state adjustment station by emitting and receiving light signals, and can also detect whether the box 2 is in the box state adjustment station by triggering.

Further, the robotic arm structure 50 is configured to controllably place the box 2 in an upright state on the base 3 after the base 3 rests at the base assembly station. That is to say, when the base 3 is driven by the base transmission mechanism 20 to move to the preset base assembly station, the second limiting structure 70 generates a second indication signal to prompt the base transmission mechanism 20 to stop running, thereby making the base 3 Let it stand and position it at the base assembly station. Then, the robotic arm structure 50 clamps the box 2 and places the box 2 above the base 3, completing the automatic assembly between the base 3 and the box 2.

It can be seen that the base 3 of the present invention only needs to be positioned once on the base transmission mechanism 20 through the second limiting structure 70, and does not need to be moved from the base transmission mechanism 20 to other positions and then positioned again. This is because the mechanical arm structure 50 can clamp the box 2 and drive the box 2 to move in any direction in the horizontal plane. It only needs to adjust the positional relationship between the work station and the base assembly station according to the preset box state. The robot arm structure 50 By setting the motion trajectory in advance, the box 2 can be accurately assembled above the base 3. That is to say, the present invention replaces the existing box flipping structure with the robotic arm structure 50, which not only simplifies the structure for flipping the box 2, but also simplifies the positioning structure of the base 3, improving the connection between the base 3 and the box 2 assembly accuracy.

Specifically, the second limiting structure 70 can be a limit sensor, which can detect whether the base 3 is in the base assembly station by emitting and receiving light signals, or can detect whether the base 3 is in the base assembly station by triggering. .

Preferably, the second limiting structure 70 can be provided at the transmission end of the base transmission mechanism 20 . The base conveying mechanism 20 and the box conveying mechanism 10 are arranged so that their conveying directions are perpendicular to each other, which can shorten the total length of the automatic base assembly equipment and facilitate assembly between the box 2 and the base 3 .

Further, one end of the robot arm rotating shaft link 52 is configured to be rotatably connected to the robot arm base 51 around a vertical axis, so as to rotate in a horizontal plane relative to the robot arm base 51 to adjust the position of the box 2 in the horizontal direction. . Specifically, the actual required rotation angle range of the mechanical arm rotating shaft link 52 can be set in advance according to the flipping process of the box 2 and the translation process of the box 2 . Theoretically, the robot arm shaft link 52 can rotate 360 degrees in the horizontal plane.

Further, one end of the robot arm lifting link 53 is configured to be rotatably connected to the other end of the robot arm rotating shaft link 52 around the horizontal axis, so as to rotate in a vertical plane relative to the robot arm rotating shaft link 52 to adjust the box. The height of body 2 in the vertical direction. Specifically, the maximum lifting amplitude of the box 2 can be estimated based on the flipping process of the box 2 and the translation process of the box 2, thereby setting the rotation angle range of the robotic arm lifting link 53 in advance. Theoretically, the robot arm lifting link 53 can rotate 360 degrees in a vertical plane relative to the robot arm rotating shaft link 52 .

Further, the robot arm rotating device 54 is configured to be rotatably connected to the other end of the robot arm lifting link 53 around a connecting shaft 57 parallel to the length direction of the robot arm lifting link 53 to rotate relative to the robot arm lifting link 53 Rotate in a plane perpendicular to the connecting axis 57 to adjust the orientation and attitude of the box 2 . Specifically, the rotation angle range of the robotic arm rotation device 54 can be preset according to the turning process of the box 2 . Theoretically, the robot arm rotation device 54 can rotate 360 degrees relative to the robot arm lifting link 53 in a plane perpendicular to the above-mentioned connection axis.

Further, the robotic arm clamping device 55 is fixedly connected to the robotic arm rotating device 54 so as to rotate synchronously with the robotic arm rotating device 54 . The robot arm clamping device 55 is used to clamp the box 2 , and a suction cup device 56 is provided on the inside of the robot arm clamping device 55 for contacting the box 2 . On the one hand, the suction cup device 56 can be used to increase the holding force of the robot arm clamping device 55 on the box 2 to avoid relative displacement between the box 2 and the robot arm clamping device 55; on the other hand, the material of the suction cup device 56 It is soft and not easy to scratch the outer surface of the box 2.

In some embodiments, the automatic base loading structure 40 includes a plurality of automatic base loading units 41 for transporting different types of bases 3 to the base transfer mechanism 20. FIG. 4 is an automatic base loading unit according to an embodiment of the present invention. Schematic structural diagram. Figure 5 is a schematic structural exploded view of an automatic base unit according to an embodiment of the present invention. Referring to FIGS. 4 and 5 , each automatic base unit 41 includes a base tool 411 , a base lifting and lowering shovel mechanism 412 , a base limiting mechanism 413 and a base clamping mechanism 414 .

Further, the base lift and shovel mechanism 412 is used to push the plurality of bases 3 resting thereon to the inside of the base tool 411 . The base limiting mechanism 413 is used to selectively support the base 3 pushed to the inside of the base tool 411 by the base lifting and lowering shovel mechanism 412 . The base clamping mechanism 414 is used to clamp other bases 3 supported on the base limiting mechanism 413 except the lowest base 3, so as to release the lowest base 3 when the base limiting mechanism 413 is in a state of not supporting the base 3. The released base 3 is transported to the base assembly station through the base transfer mechanism 20 to wait for assembly with the box 2.

In order to improve assembly efficiency, assemblers usually stack multiple bases 3 in the base lifting and shoveling mechanism 412 at one time. The base lifting and pushing shovel mechanism 412 pushes the multiple bases 3 to the inside of the base tooling 411 at the same time. It is not necessary to assemble them each time. Each base 3 requires the base lifting and shoveling mechanism 412 to perform one process, which saves assembly time and improves assembly efficiency.

In some embodiments, the number of the base limiting mechanisms 413 is two. The two base limiting mechanisms 413 are arranged oppositely in the horizontal direction to respectively support the opposite sides of the base 3, thereby improving the support stability of the base 3. sex. Figure 6 is a schematic structural diagram of a base limiting mechanism according to an embodiment of the present invention. Each base limiting mechanism 413 includes a limiting support plate 4131 and a limiting cylinder 4132 for driving the limiting support plate 4131 to reciprocate in the arrangement direction of the two base limiting mechanisms 413 .

Specifically, the limit cylinder 4132 can be configured to controllably drive the limit support plate 4131 to extend in a direction close to the other base limit mechanism 413 after the base lift shovel mechanism 412 pushes the base 3 into the interior of the base tool 411. The base 3 is supported by the limiting support plate 4131. After the base clamping mechanism 414 clamps the other bases 3 except the bottom base 3, the limiting supporting plate 4131 is controlled to drive away from the other base limiting mechanism. The direction of 413 is retracted to release the base 3 at the bottom. When the bottom base 3 is released, the limit cylinder 4132 drives the limit support plate 4131 again to extend into the internal space of the base tool 411 so that the base limit mechanism 413 can support the remaining bases 3 again.

Furthermore, the limiting cylinders 4132 of the two base limiting mechanisms 413 can act synchronously. That is to say, when the two limiting cylinders 4132 of the two base limiting mechanisms 413 drive the two limiting support plates 4131 to move toward each other at the same time, the two limiting supporting plates 4131 extend into the internal space of the base tool 411 and can support The base 3 is located in the base tool 411; when the two limit cylinders 4132 of the two base limit mechanisms 413 drive the two limit support plates 4131 to move away from each other at the same time, the two limit support plates 4131 are moved by the base tool 411. The internal space shrinks and resets outward, and cannot support the base 3 located in the base tool 411.

In some embodiments, the number of the base clamping mechanisms 414 is two, and the two base clamping mechanisms 414 are arranged oppositely in the horizontal direction for applying opposing clamping forces to opposite sides of the base 3 . Figure 7 is a schematic structural diagram of a base clamping mechanism according to an embodiment of the present invention. Each base clamping mechanism 414 includes a vertically extending positioning clamping plate 4141 and a clamping cylinder 4142 for driving the positioning clamping plate 4141 to reciprocate in the arrangement direction of the two base clamping mechanisms 414 . Since the bases 3 have a relatively high height when stacked, the vertically extending positioning clamping plates 4141 can clamp multiple bases 3 at the same time.

Specifically, the clamping cylinder 4142 may be configured to controllably drive the positioning clamping plate 4141 after the base 3 is supported on the base limiting mechanism 413 to apply clamping force to other bases 3 except the base 3 located at the bottom. After the support effect of the base limiting mechanism 413 on other bases 3 disappears, it can still hold other bases 3 . After the base limiting mechanism 413 releases the lowermost base 3 and is in a state that can support the remaining bases 3 again, the support for other bases 3 is released. The clamping function of the base 3 allows other bases 3 to drop to the base limiting mechanism 413. At this time, the base clamping mechanism 414 clamps the other bases 3 except the lowest base 3 again, and so on.

In some embodiments, the two base limiting mechanisms 413 and the two base clamping mechanisms 414 are respectively located on opposite sides of the base tool 411 in the conveying direction of the base conveying mechanism 20 .

Figure 8 is a schematic structural diagram of a base lifting and lowering shovel mechanism according to an embodiment of the present invention. In some embodiments, the base lifting and lowering blade mechanism 412 is located outside the base tool 411, and the base lifting and lowering blade mechanism 412 includes a base platform 4121, a lifting cylinder 4122, a third limiting structure 4123, a base blade 4124 and a blade cylinder. 4125.

Further, the base platform 4121 extends horizontally for the base 3 to rest on it. The lifting cylinder 4122 is used to drive the base platform 4121 to lift. The third limiting structure 4123 is used to generate a third indication signal after the base platform 4121 rises to the preset highest position. The third indication signal is used to prompt the lifting cylinder 4122 to stop running, so that the base platform 4121 remains at the preset highest position. . The base push shovel 4124 is arranged vertically on the side of the base platform 4121, and rises and falls synchronously with the base platform 4121, and is used to push the base 3 on the base platform 4121. The dozer cylinder 4125 is used to selectively drive the base dozer 4124 to move inside the base tool 411 or to drive the base dozer 4124 to move outside the base tool 411 .

Specifically, the lifting cylinder 4122 is configured to lift the base platform 4121 to a preset highest position after receiving the corresponding instruction. The dozer cylinder 4125 is used to controlly drive the base dozer 4124 to move toward the inside of the base tool 411 after the base platform 4121 remains at the preset highest position to push the base 3 on the base platform 4121 to the base tool 411 through the base dozer 4124. The base 3 inside and on the base platform 4121 is supported by the base limiting mechanism 413, and then the base shovel 4124 is controlled to move toward the outside of the base tool 411 and reset. Then, the lifting cylinder 4122 lowers and resets.

Further, the clamping force generated by the base clamping mechanism 414 on the base 3 is perpendicular to the direction in which the base lifting and lowering shovel mechanism 412 pushes the base into the base tool 411 to prevent the base lifting and lowering shovel mechanism 412 from colliding with the base clamping mechanism 414 produce structural interference.

In some embodiments, the automatic upper base structure 40 also includes a conveyor belt 42 that runs through each automatic upper base unit 41 and is located below the base limiting mechanism 413 of each automatic upper base unit 41 to receive each base limiting mechanism. 413 releases the base 3, and transfers the base 3 released by each base limiting mechanism 413 to the base transfer mechanism 20.

Specifically, the conveying direction of the conveyor belt 42 may be consistent with the conveying direction of the base conveying mechanism 20 so that the base 3 on the conveyor belt 42 falls on the base conveying mechanism 20 .

In some embodiments, each automatic base loading unit 41 further includes an emergency stop switch 415 , and the emergency stop switch 415 is configured to generate an emergency stop signal for prompting the automatic base loading structure 40 to stop operating when triggered. When the automatic base unit 41 is running, if an emergency occurs, the entire automatic base unit 41 can be forced to stop operating by manipulating the emergency stop switch 415 to avoid potential safety hazards.

Specifically, the emergency stop switch 415 can be provided on the outer surface of the base lifting and lowering shovel mechanism 412 away from the base tool 411 to facilitate access and manipulation by assembly personnel.

In some embodiments, each automatic base unit 41 further includes a base positioning plate 416 and a base positioning post 417 . The base tool 411 has a base push-in port that allows the base 3 to enter its interior. The base positioning plate 416 is provided on the side of the base tool 411 opposite to the base push-in port to abut the base 3 pushed into the base tool 411, thereby positioning the base 3 is positioned to ensure that multiple bases 3 are neatly stacked inside the base tooling 411, and to facilitate subsequent positioning of the bases 3. The base positioning posts 417 are distributed around the inside of the base tool 411 to position the surroundings of the base pushed into the base tool 411 to further ensure the cleanliness of the base 3 .

The work flow of the base automatic assembly equipment 1 described in the embodiment of the present invention is as follows:

After the box 2 is foamed, it is sent out through the box conveying mechanism 10. When the box 2 passes through the identification device 30, the identification device 30 identifies the type of the box 2. The PLC control system used to control the base automatic assembly equipment 1 is based on the box 2 The type matches the corresponding base 3, and sends corresponding instructions to the automatic upper base structure 40.

When the box 2 moves to the first limiting structure 60 driven by the box conveying mechanism 10, the box conveying mechanism 10 stops running, the box 2 rests at the box state adjustment station, and the robotic arm structure 50 moves. The robotic arm structure 50 clamps and flips the box 2, and adjusts the box 2 to an upright state and suspends it in the air.

After receiving the corresponding instruction, the automatic base uppering structure 40 triggers the corresponding automatic base uppering unit 41 to perform a series of actions: the base lifting and lowering shovel mechanism 412 pushes the base 3 to the inside of the base tooling 411, and the base limiting mechanism 413 supports the base 3 , the base clamping mechanism 414 clamps other bases 3 except the base 3 at the bottom, the base limiting mechanism 413 releases the supporting function to release the base 3 at the bottom to the conveyor belt 42, and then the base limiting mechanism 413 recovers In the state of supporting the base 3, the base clamping mechanism 414 releases the clamping function to release the remaining base 3. The remaining base 3 falls on the base limiting mechanism 413, and the base clamping mechanism 414 re-clamps the base 3 except for the bottom one. Other than base 3.

The released base 3 is driven by the base transmission mechanism 20 to move. When the base 3 moves to the second limiting structure 70 , the base transmission mechanism 20 stops running, and the base 3 rests at the base assembly station. At this time, the robot arm structure 50 moves the upright box 2 held by it to above the base 3 and lowers the box 2 so that the box 2 is assembled on the base 3 .

Preferably, the action of the robotic arm structure 50 clamping and flipping the box 2 can be performed simultaneously with the action of the automatic upper base structure 40 automatically screening and outputting the base 3, so as to save assembly time and improve assembly efficiency.
