Technical Field

[0001] The utility model relates to the technical field of fully automatic loading and unloading machines, in particular to a lifting device of a fully automatic loading and unloading machine. Background Technique

[0002] A fully automatic loading and unloading machine is an important device in modern automated production lines. It can achieve precise handling and efficient transmission of materials, and is widely used in multiple industries such as electronics, electrical appliances, automobiles, medical treatment, and food. A fully automatic loading and unloading machine is also called an automatic board feeder or board collector. It is an automated device integrating machinery, electronics, and control. It is mainly used for material loading and unloading operations on production lines and can automatically transfer materials (such as circuit boards, components, etc.) from one device to another, or from one end of the production line to the other end.

[0003] Currently, during the use of a fully automatic loading and unloading machine, since the heights for taking materials from the loading frame and placing them into the unloading frame are different, only special loading and unloading frames can be used. If ordinary loading and unloading frames are replaced, the device cannot ensure stable material taking and unloading operations, and the applicability is poor.

[0004] Therefore, a lifting device of a fully automatic loading and unloading machine is proposed to solve the above problems. Content of the Utility Model

If ordinary loading and unloading frames are replaced, the device cannot ensure stable material taking and unloading operations, and the applicability is poor.

[0007] 2. Technical Solution

[0008] To achieve the above purpose, the utility model provides the following technical solution:

[0009] A lifting device for a fully automatic upper and lower plate machine, comprising a base. At the center of the top of the base, a stepping motor capable of rotating at a fixed angle is installed. At the top of the stepping motor, a column is fixedly installed. On one side surface of the column, a support mechanism is slidably installed. On the support mechanism, a support rod is installed. At one end of the support rod, a feeding mechanism is installed. On the feeding mechanism, a feeding rack is installed. At the bottom of both side surfaces of the feeding rack, side plates are symmetrically installed. At both ends of the bottom of each side plate, distance sensors with the bottom flush with the bottom of the feeding rack are symmetrically embedded. At the four corners of the bottom of the feeding rack, electric suction cups are installed. The distance between the bottom of the distance sensor and an object is the same as the distance from the bottom of the distance sensor to the bottom of the electric suction cup.

[0010] As a preferred solution of the present utility model, at the four corners of the bottom of the base, a pulley and a connecting cylinder are installed. The pulley is farther from the corner of the base. Four card slots are equidistantly arranged on the outer ring surface of the connecting cylinder. At the bottom of the connecting cylinder, a support angle is installed. On the round rod at the top of the support angle, four pressable and telescopic buckles are installed up and down. After the round rod at the top of the support angle is inserted into the inside of the connecting cylinder, the buckles can be snapped into the inside of the card slots. The bottom of the connecting cylinder is higher than the bottom of the pulley.

[0011] As a preferred solution of the present utility model, the rotation angle of the stepping motor is 180°, and the next rotation will be in the reverse direction by 180°. The column is driven by the stepping motor to rotate back and forth at a fixed angle.

[0012] As a preferred solution of the present utility model, a chute is arranged on the outer side surface of the column. At the top of the column, a forward and reverse motor is installed. One end of the rotating shaft of the forward and reverse motor is connected to a lead screw. The lead screw extends into the inside of the column and is rotatably connected to the bottom of the inner side surface of the column.

[0013] As a preferred solution of the present utility model, one end of the support rod is fixedly connected to a sliding seat. At the top and bottom of one side surface of the sliding seat, connecting plates are symmetrically installed. At one end of each connecting plate, a threaded hole is opened.

The support mechanism slides on the column to enable the loading mechanism to move up and down. The loading mechanism adsorbs the top of the material plate through the electric suction cup at the bottom of the loading rack to complete the material taking. When the loading rack moves to the unloading frame, the suction force of the electric suction cup is turned off and the material plate can be unloaded. During this process, the distance between the bottom of the loading rack and the top of the material plate is monitored by the distance sensor, so that it can be controlled to stop moving downward just when the electric suction cup is exactly located on the top of the material plate each time. Therefore, the loading mechanism can be applied to various loading and unloading frames, not limited to the use of special frames, thus improving the applicability of the device.

Specific implementation manners

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment:

[0026] Please refer to Figures 1-4 , this embodiment provides a lifting device for a full-automatic upper and lower plate machine, including a base 1. A stepping motor 15 capable of rotating at a fixed angle is installed at the center of the top of the base 1. A column 2 is fixedly installed at the top of the stepping motor 15. A support mechanism 4 is slidably installed on one side surface of the column 2. A support rod 44 is installed on the support mechanism 4. One end of the support rod 44 is installed with a feeding mechanism 5. A feeding frame 51 is installed on the feeding mechanism 5. Side plates 53 are symmetrically installed at the bottoms of both side surfaces of the feeding frame 51. Distance sensors 54 with the bottoms flush with the bottom of the feeding frame 51 are symmetrically and embeddedly installed at both ends of the bottom of the side plate 53. Electric suction cups 52 are installed at the four corners of the bottom of the feeding frame 51. The distance between the bottom of the distance sensor 54 and the object is the same as the distance from the bottom of the distance sensor 54 to the bottom of the electric suction cup 52. When this automatic upper and lower plate machine lifting device is in use, the column is driven to rotate by the stepping motor 15 to realize the rotation of the feeding mechanism 5 at a fixed angle. The support mechanism 4 slides on the column 2 to enable the feeding mechanism 5 to move up and down. The feeding mechanism 5 adsorbs the top of the material plate through the electric suction cups 52 at the bottom of the feeding frame 51 to complete material taking. When the feeding frame 51 moves to the blanking frame, the material plate can be completed by turning off the suction force of the electric suction cup 52. During this process, the distance between the bottom of the feeding frame 51 and the top of the material plate is monitored by the distance sensor 54, so that it can be controlled to stop moving downward just when the electric suction cup 52 is exactly located at the top of the material plate each time. Therefore, the feeding mechanism 5 can be applicable to a variety of upper and lower blanking frames, not limited to the use of special blanking frames, thereby improving the applicability of the device.

[0027] In this embodiment, as Figure 1 and Figure 4As shown, a pulley 11 and a connecting cylinder 12 are installed at each of the four bottom corners of the base 1. The pulley 11 is farther from the corner of the base 1. Four card slots are equidistantly arranged on the outer ring surface of the connecting cylinder 12. A support angle 13 is installed at the bottom of the connecting cylinder 12. Four pressable and telescopic buckles 14 are installed vertically on the round rod at the top of the support angle 13. After the round rod at the top of the support angle 13 is inserted into the inside of the connecting cylinder 12, the buckle 14 can be snapped into the inside of the card slot. The bottom of the connecting cylinder 12 is higher than the bottom of the pulley 11. Therefore, when moving is needed, the support angle 13 is removed and the sliding is carried out through the pulley 11. When stable support is needed, the support angle 13 is installed.

[0028] In this embodiment, as Figure 2 and Figure 4 shown, one end of the support rod 44 is fixedly connected with a sliding seat 41. Connecting plates 42 are symmetrically installed at the top and bottom of one side surface of the sliding seat 41. Threaded holes 43 are opened at one ends of the two connecting plates 42. One ends of the two connecting plates 42 pass through the inside of the sliding groove 21 and enter the inside of the column 2, and the threaded holes 43 are threadedly connected with the lead screw 31. Therefore, when the positive and negative motor 3 rotates, the sliding seat 41 can be driven by the lead screw 31 to slide up and down on the outer side surface of the column 2.

[0029] In this embodiment, as Figure 1 and Figure 2 shown, a sleeve 45 is sleeved and installed on the outer ring surface of the support rod 44. An electric push rod 46 is connected to the bottom of the sleeve 45. One end of the electric push rod 46 is connected with a push plate 47. The bottom of the push plate 47 is lower than the bottom of the electric suction cup 52. The push plate 47 is in a parallel state with one end of the loading rack 51. Therefore, after the electric suction cup 52 puts down the material plate, the push plate 47 can be pushed by the electric push rod 46 to push the material plate to the inside of the material frame to be aligned.

[0030] In this embodiment, as Figure 1 and Figure 3 shown, one end of the side plate 53 extends to the outside of the loading rack 51. When the electric suction cup 52 sucks the material plate, the extended end of the side plate 53 is located outside the material plate and the other end of the side plate 53 is located on the top of the material plate. The distance sensor 54 at the extended end of the side plate 53 monitors during unloading, and another distance sensor 54 monitors during loading. When the distance sensor 54 monitors that the distance to the object reaches the set distance value, the positive and negative motor 3 immediately stops. Therefore, during loading and unloading, the distance sensor 54 will not be blocked by the material plate, and at the same time, the up and down lifting distance of the loading rack 51 can be controlled.

[0031] Working principle: When the lifting device of this automatic loading and unloading machine is in use, first, when the device needs to move, the support angle 13 is removed and it slides through the pulley 11. When stable support is required, the support angle 13 is installed. At the same time, the column is driven to rotate by the stepping motor 15 to realize the rotation of the feeding mechanism 5 at a fixed angle. The positive and negative motor 3 drives the lead screw 31 to rotate, so that the lead screw 31 drives the sliding seat 41 to move up and down through the threaded hole 43, realizing the up and down lifting of the feeding mechanism 5. When taking materials, the feeding frame 51 moves downward. When the distance sensor 54 monitors that the distance between it and the top of the material plate is the same as the set value, the positive and negative motor 3 stops. At this time, the electric suction cup 52 sucks the material plate. When discharging, the distance sensor 54 at the longer end of the side plate 53 monitors the distance between its bottom and the discharging frame. Therefore, during loading and unloading, the distance sensor 54 will not be blocked by the material plate, and at the same time, the up and down lifting distance of the feeding frame 51 can be controlled. When the feeding frame 51 moves to the discharging frame, the suction of the electric suction cup 52 is turned off and the material plate can be discharged. During this process, the distance between the bottom of the feeding frame 51 and the top of the material plate is monitored by the distance sensor 54, so that it can be controlled that the electric suction cup 52 just stops moving downward when it is exactly at the top of the material plate each time. Therefore, the feeding mechanism 5 can be applicable to a variety of loading and unloading frames, not limited to the use of special frames, thereby improving the applicability of the device.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
