DETAILED DESCRIPTION

[0063] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0064] like Figure 1-Figure 26As shown, the present invention provides an automatic palletizing device including a material receiving belt line 1, a tooling vehicle 2, a robot 3, a guiding mechanism 4, and a material receiving mechanism 5; wherein:

[0065] The material receiving belt line 1 is arranged between the material unloading position of the processing equipment and the stacking product stacking area, and is mainly used to connect the punch press 100 mold, receive the products dropped from the mold, and can transport the products to the stacking area through the material unloading position;

[0066] There is at least one guiding mechanism 4, which is arranged along the conveying direction of the material receiving belt line 1 to perform at least one direction correction on the product that falls on the material receiving belt line 1; it is used to guide the motor bracket 300 with a disordered direction and position to the angle and position we need, which is convenient for subsequent guidance and stacking; when in use, the product flows to the guiding mechanism 4, the width is limited by the guiding plate, and the angle is limited by the baffle. After blocking, the cylinder with the baffle retreats, and the product then flows down the belt line. After this process, the position and angle of the motor bracket 300 on the belt line are basically consistent.

[0067] The material receiving mechanism 5 is arranged at the end of the material receiving belt line 1, and is used to stack the products delivered to the place;

[0068] The robot 3 is arranged at the end of the receiving belt line 1 and is used to grab the stacked products;

[0069] The tooling vehicles 2 are arranged on both sides of the receiving belt line 1 to receive the products grabbed by the robot 3 for stacking.

[0070] The automatic stacking device provided by the present invention can realize the angle adjustment of the products dropped onto the receiving belt line 1, make the angles of all products consistent, automatically complete the angle guidance, and then complete the automatic material collection and stacking, thereby realizing the automation of the workstation, reducing the number of staff and reducing the labor intensity. It can be seen from actual application that the number of staff is reduced by 2.

[0071] It should be noted that the automatic stacking device of the present invention is applicable to a variety of products, as long as the product direction is inconsistent when it automatically falls onto the belt line, and the product needs to be collected and stacked at the end, it is not limited to the air conditioner outdoor motor bracket 300 product introduced below in the present invention. Of course, when changing to other products, such as other types of brackets, it is necessary to adjust the structure of the material receiving mechanism 5 in the present invention according to the product structure details. For example, if it is not a right angle, modify the shape of the positioning frame 51 in the end material receiving mechanism 5. For non-metallic products, it is necessary to change the way the robot 3 sucks at the end. At present, the gripping method used for the air conditioner outdoor motor bracket 300 of the present invention is magnetic suction, which can only suck materials that the magnet 32 ​​can stick to. If it is a non-metallic product, it is necessary to modify the clamping method.

[0072] Furthermore, the present invention also includes an electric control cabinet 200, which is arranged beside the material receiving belt line 1 and is used to control and supply power to the electric control products in the entire automatic palletizing device.

[0073] As an optional embodiment of the present invention, the material receiving belt line 1 is not a straight conveying mode, but a conveying mode with an inclined angle. Specifically, the material receiving belt line 1 includes a straight conveying section 11 and an inclined conveying section 12. The straight conveying section 11 is located at the unloading position of the processing equipment, and is used to receive the products that automatically fall after processing; in order to make the products take up less space when stacking, it is necessary to stack the motor brackets 300 together, and the inclined conveying section 12 is located in the stacking area to achieve product alignment when stacking; the guide mechanism 4 is arranged in the straight conveying section 11. When the guide mechanism 4 is arranged only in the straight conveying section 11, it is required to complete the angle correction processing of the product in the straight conveying section 11. At this time, one or more guide mechanisms 4 can be arranged in the straight conveying section 11 for one or more correction processing of the product; but considering that the material receiving belt line 1 of the present invention includes the inclined conveying section 12, in order to avoid After the product is aligned in the straight conveying section 11, when it enters the inclined conveying section, due to some reasons, it deflects slightly when entering the material receiving mechanism 5, which affects the stacking of the product. Therefore, as the optimal embodiment of the present invention, the guiding mechanism 4 is respectively arranged in the straight conveying section 11 and the inclined conveying section 12, that is, the angle of the product is aligned by the guiding mechanism 4 in the straight conveying section 11, and the angle of the product is aligned again before entering the material receiving mechanism 5, thereby ensuring the angle consistency of the product when entering the material receiving mechanism 5, and facilitating the automatic stacking process of the product; of course, it should be noted that although the guiding mechanism 4 is respectively arranged in the two conveying sections, the guiding mechanism 4 located in each conveying section can also be arranged into one or more, which can be optionally arranged according to the length of the conveying section and the complexity of the product appearance, and the present invention does not make specific limitations on this; the material receiving mechanism 5 is arranged in the inclined conveying section 12.

[0074] The following is a specific description of the second embodiment, that is, both the straight conveying section 11 and the inclined conveying section 12 are provided with the guide mechanism 4. Specifically, there are two guide mechanisms 4, including a first guide mechanism 4 and a second guide mechanism 4.

[0075] Specifically, the first guiding mechanism 4 includes a rodless cylinder 411, a first baffle 412, and a first guiding plate 413; wherein:

[0076] The first guide plate 413 is arranged in a trumpet shape on both sides of the material receiving belt line 1 to perform angle correction on the passing products; the width of the small end of the first guide plate 413 is equal to the length of the product.

[0077] Furthermore, the first guide plate 413 includes two arc-shaped plates, which are fixed at both ends of the material receiving belt line 1 through a base plate; the arc-shaped plate includes a first straight section and an arc section; the first straight section is shorter, while the arc section is longer, and the angle between the arc section and the first straight section is an obtuse angle. The width of the large opening end of the first guide plate 413 is greater than the length of the product, so as to facilitate the smooth entry of the product. When the product enters the first guide plate 413, due to the smaller and smaller width of the first guide plate 413, it will first contact one side of the product to play a certain blocking role, and the other side will move faster than the contacting side under the drive of the material receiving belt line 1, thereby forming an angle correction process of the product, and finally the two ends of the product are respectively in contact with the first guide plate 413 to achieve angle adjustment; in order to ensure that the angle adjustment of the product can be completed here, a first baffle 412 is provided on the outlet side of the first guide mechanism 41; that is, the first baffle 412 is arranged at the small opening end of the first guide plate 413 to form a first conveying port of the first guide mechanism 41; in the process of product angle correction, the first baffle 412 can be controlled to close the first conveying port. At this time, even if the product reaches the small opening end of the first guide plate 413, if the angle still has deviation, it can pass through the first baffle. The blocking of plate 412 realizes the angle adjustment process again; because the product cannot continue to move forward due to the obstruction of the first baffle plate 412, but the material receiving belt line 1 is still running, the product still has the power to be brought forward, and the width of the small mouth end of the first guide plate 413 is consistent with the product width. If there is a small deviation, the contact positions of the two ends of the surface product and the first guide plate 413 are different, and the angle adjustment control can be continued through the first baffle plate 412. Once the adjustment is completed, the first baffle plate 412 can be opened to allow the product to pass smoothly; and there are many ways to control the opening and closing of the first baffle plate 412, such as lifting, rotating, and telescopic; in this embodiment, the telescopic control method is listed; specifically, there are two rodless cylinders 411, which are respectively arranged on both sides of the material receiving belt line 1, and each rodless cylinder 411 is transmission-connected to a first baffle plate 412 to drive the first baffle plate 412 to move in a close or distant manner, thereby closing the conveying port or opening the first conveying port.

[0078] It should be noted that in order to save materials, reduce costs, and increase the speed of switching, when the first baffle 412 is close, there is no need for contact between the two, and there can be an opening, and the opening specification can be equal to 1 / 4-1 / 2 of the product length.

[0079] After passing through the first guiding mechanism 41 on the material receiving belt line 1, the position angle consistency of the product on the belt line is relatively good. In order to make the subsequent stacking more stable, we use a set of second guiding mechanism 4 to adjust the product position angle consistency to meet the use requirements of stacking. Further, the second guiding mechanism 422 includes a second guiding plate 421, a slide cylinder 422, and a second baffle 423; wherein:

[0080] There are two slide cylinders 422, which are arranged on both sides of the material receiving belt line 1;

[0081] The two second baffles 423 are both L-shaped structures, one free end of which is connected to the two slide cylinders 422 respectively, and the other free end is arranged opposite to form a second conveying port of the second guide mechanism 42;

[0082] There are two second guide plates 421, which are respectively fixed on two slide cylinders 422, and the two second guide plates are arranged in a bell-mouth shape. When the slide cylinder 422 is in the initial position, the width of the small end between the two second guide plates is equal to the length of the product.

[0083] It should be noted that the second guide plate 421 includes two bending plates, the straight section of the bending plate is fixed on the slide cylinder 422, and the angle between the bending section and the straight section of the bending plate is an obtuse angle; in this embodiment, the length of the straight section of the bending plate is short, and the length of the bending section is long, but the length difference between the bending section and the straight section is smaller than the length difference between the first straight section and the arc section of the arc plate of the first guide plate 413.

[0084] It should be noted that in order to save materials, reduce costs, and increase the speed of switching, when the two second baffles 423 are close to each other, there is no need for the ends to touch each other, and there can be an opening between the two; and due to the angle adjustment function of the first guiding mechanism 41, the angle of the product has basically met the requirements or has already met the requirements during the second guidance, so the opening specifications between the second baffles 423 can be larger than the opening specifications between the first baffles 412. In this embodiment, the opening specifications between the two second baffles 423 can be smaller than the product length.

[0085] When in use, the two slide cylinders 422 each carry an L-shaped second baffle 423. When the motor bracket 300 falls, the L-shaped second baffle 423 blocks the motor bracket 300. Driven by the belt, the motor bracket 300 will be adjusted to a consistent position and angle. Then the two slide cylinders 422 retract at the same time, and the motor bracket 300 slides along the belt to the end material receiving mechanism 5 and stacks up. After 8 pieces are stacked here, they form a group and wait for the robot 3 to absorb them. The main reason why the belt line is made into an inclined surface here is that the surface of the motor bracket 300 is uneven and the flat belt plus the blocking motor bracket 300 is easy to warp up. The inclined belt is mainly to solve the problem of the motor bracket 300 warping up after the blocking (the inclined surface is equivalent to a lower break, which is not easy to warp up).

[0086] As an optional embodiment of the present invention, the material receiving mechanism 5 includes a positioning frame 51 and a material guiding rod 52; wherein:

[0087] The guide rod 52 is arranged in a bell-mouth shape to assist in final positioning;

[0088] The positioning frame 51 is arranged at the downstream position of the guide rod 52, and the positioning frame 51 has a contour structure adapted to the shape of the product to be stacked, so as to perform contour stacking on the product introduced by the guide rod 52. In this embodiment, the receiving mechanism 5 is assembled with aluminum profiles, which is convenient for debugging and changing the position.

[0089] It should be noted that the product has undergone two angle corrections and meets the requirements of all angles being consistent, so the straight section of the trumpet-shaped guide rod 52 here is longer, while the curved section is very short, which is only used for prevention and is basically not used; the straight section of the guide rod 52 is used to ensure that the product can smoothly enter the positioning frame 51 for stacking and wait for the robot 3 to grab it.

[0090] As an optional embodiment of the present invention, since this embodiment illustrates the automatic stacking of the motor bracket 300 of the air conditioner outdoor unit, in this embodiment, the shape and structure design of the positioning frame 51 meets the shape of the motor bracket 300. If it is replaced with other products, corresponding improvements can be made. Since the motor bracket 300 of the air conditioner outdoor unit is a U-shaped structure, including two right angles. Therefore, in order to facilitate the stacking of the motor bracket 300, two right-angled parts are also formed in the positioning frame 51 of the present invention to correspond to the two right-angle positions of the motor bracket 300 respectively. Specifically, the positioning frame 51 includes a first frame 511 and a second frame 512; the first frame 511 is an L-shaped structure, and its first corner is adapted to the angle shape of the product; the second frame 512 is connected to a straight edge of the first frame 511 to form a second corner, and the distance between the second corner and the first corner is equal to the distance from the corner of the product to the end, that is, another right-angle position corresponding to the motor bracket 300.

[0091] It should be noted that the tooling trolley 2 is used to load the motor bracket 300 product, and is generally equipped with casters 22 for easy pushing and moving. During the material grabbing and placing process of the robot 3, if the tooling trolley 2 cannot be fixed, there is a risk of displacement of the tooling trolley 2, which may easily cause the stacking position to be unstable and lead to the problem of failure in stacking products. Therefore, in this embodiment, a positioning mechanism 6 for limiting the placement position of the tooling trolley 2 is also included. The tooling trolley 2 is limited to the side of the material receiving belt line 1 by the positioning mechanism 6.

[0092] Specifically, the positioning mechanism 6 includes a U-shaped limit frame 61, a rotary tensioning cylinder 62, and a tensioning strip 63; wherein:

[0093] The opening width of the limiting frame 61 is equal to the width of the tooling vehicle 2;

[0094] A roller 64 is provided on the inner wall of the limiting frame 61 for guiding the vehicle to move in;

[0095] The rotating tensioning cylinder 62 is arranged on the cross beam of the limiting frame 61, and the end is connected to the tensioning strip 63. When in use, there is a matching mechanism on the tooling vehicle 2, and a cross beam is set. When the rotating tensioning cylinder 62 rotates upward, the tensioning strip 63 is used to hook the cross beam. When it is extended horizontally, the tensioning strip 63 of the rotating tensioning cylinder 62 is just under the cross beam.

[0096] After the tooling trolley 2 is pushed into place, the tooling trolley 2 is clamped by the rotating tensioning cylinder 62 to prevent it from loosening.

[0097] In this embodiment, the tooling vehicle 2 includes a vehicle body 21, casters 22, and a cross partition 23; the vehicle body 21 is a frame structure, and the cross partition 23 is placed inside the vehicle body 21, which is used to divide the inner cavity of the vehicle body 21 into multiple stacking areas, isolate products, and prevent the motor bracket 300 from sliding to the side and affecting loading at other locations; the casters 22 are located at the four corners of the bottom of the vehicle body 21, and two of the four casters 22 are universal wheels, and two are ordinary wheels, which are convenient for pushing.

[0098] A clamp 31 is provided at the end of the arm of the robot 3, and two magnets 32 are provided at the bottom of the clamp 31. Considering the shape characteristics of the product and the overall size of the stacked products, the lengths of the two magnets 32 should meet the overall size requirements of the stacked products, and one of the magnets 32 is an inclined setting structure.

[0099] When in use, after the eight motor brackets 300 are stacked into a fan-like shape, the robot 3 grabs them and puts them into the tooling vehicle 2. The robot 3 clamp 31 adopts a magnetic suction mode, using two rectangular electromagnets 32 to respectively absorb the long side and short side of the motor bracket 300. The magnetic suction clamp 31 has good adaptability, and even if the consistency of the motor bracket 300 is not very good when stacked into a fan shape, it does not affect the suction.

[0100] The automatic stacking device of the present invention realizes auxiliary automatic stacking through the guiding mechanism 4, and performs strong magnetic absorption through the magnet 32 ​​and the clamp 31 of the robot 3.

[0101] The present invention provides a production line, which includes the above-mentioned automatic palletizing device and a punching machine 100 for punching a motor bracket 300 of an air conditioner outdoor unit.
