[0047] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it is to be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally disposed component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally disposed component.

[0049] In addition, terms such as "long", "short", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific direction or operate with a specific direction structure, and should not be understood as a limitation of the present invention.

[0050] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0051] This embodiment provides an automatic hanging device, including a tension hanger 1 for hanging a workpiece 2 and a hanging mechanism for removing the workpiece 2 from the tension hanger 1 .

[0052] See also Figure 1-2 The tension hanger 1 is used to hang a workpiece 2 with a hanging space, and includes a cross bar 101 and a plurality of hanging branch assemblies; each group of the hanging branch assemblies includes two hanging branch rods 102, the upper ends of the two hanging branch rods 102 are fixedly connected to the cross bar 101, and a spacing distance 103 is provided between the lower ends of the two hanging branch rods 102; the lower ends of the two hanging branch rods 102 extend into the hanging space to hang the workpiece 2, and when the spacing distance 103 is reduced, the workpiece 2 slides down to detach from the hanging branch assembly.

[0053] It should be noted that the hanging space can be in various forms, which are not limited in this embodiment. Figure 3 The hanging space can be a straight groove 201 with an open top. The lower ends of the two hanging rods 102 press against the groove wall of the straight groove 201 in a direction away from each other to achieve the hanging of the workpiece 2. When the spacing distance 103 is reduced, the maximum static friction between the hanging rods 102 and the groove wall of the straight groove 201 decreases or even disappears, so the workpiece 2 automatically slides down. Or, see Figure 4 The hanging space is two hanging holes 202, each hanging branch rod 102 extends into a hanging hole 202, so as to realize the hanging of the workpiece 2. When the spacing distance 103 is reduced, the hanging branch rod 102 is separated from the hanging hole 202, and the workpiece 2 automatically slides down. Or, see Figure 5 The hanging space is a cavity 203 with an opening at the upper end. When the spacing distance 103 is larger than the size of the upper opening, the workpiece 2 is mounted on the hanging branch assembly. When the spacing distance 103 is reduced to be smaller than the size of the upper opening, the workpiece 2 automatically slides from the lower end of the hanging branch rod 102 to complete the hanging.

[0054] See also Figure 6 The lower hanging mechanism is fixed to the top of the frame 3, and includes a fixing component for fixing the cross bar 101 and a squeezing component 5 for squeezing the hanging branch component to reduce the spacing distance 103 thereof.

[0055] See also Figure 7 The fixing assembly is fixed on the top of the frame 3, and includes a first fixing seat 401, a second fixing seat 402, a stop plate 403, a first elastic pressing member 404 and a second elastic pressing member 405. Figure 8 The first fixing seat 401 is provided with a plug hole 4011 with an opening facing the horizontal direction, and the plug hole 4011 can be inserted into one end of the cross bar 101. Fig. 9The second fixing seat 402 is provided with a U-shaped groove 4021 with an opening facing upward, and the U-shaped groove 4021 can be inserted into the other end of the cross bar 101. The stop plate 403 is fixed to the side of the second fixing seat 402 away from the first fixing seat 401. The first elastic pressing component 404 is located at the bottom of the hole 4011, and is used to push the cross bar 101 toward the stop plate 403 along the length direction of the cross bar 101. The second elastic pressing component 405 is located on both sides of the U-shaped groove 4021, and is used to push the cross bar 101 toward the groove wall of the U-shaped groove 4021 along the radial direction of the cross bar 101.

[0056] Specifically, when the workpiece 2 is mounted on the tension hanger 1, one end of the cross bar 101 is first inserted into the socket 4011, and then the first elastic top mechanism is squeezed, and then the other end of the cross bar 101 is placed at the notch of the U-shaped groove 4021, and it is pressed down hard to make the cross bar 101 fit into the U-shaped groove 4021. After releasing the hand, the first elastic tightening component 404 extends out, and then pushes the cross bar 101 against the stop plate 403 and cooperates with the stop plate 403 to limit the longitudinal direction of the cross bar 101, and the second elastic tightening component 405 extends out and tightens the cross bar 101 from the radial direction to achieve the lateral direction limitation of the cross bar 101, thereby avoiding the swing of the cross bar 101 during the sliding and hanging process of the lower hanging mechanism.

[0057] Of course, a third elastic pressing component may also be provided on the stop plate 403 to cooperate with the first elastic pressing component 404 to press the cross bar 101 along the length direction of the cross bar 101 .

[0058] Optionally, the first elastic pressing component 404, the second elastic pressing component 405 and the third elastic pressing component may be compression springs or spring ejectors, etc.

[0059] In this embodiment, see Figure 8 and Fig.10 The squeezing assembly 5 comprises a sliding plate 501 and two squeezing rollers 502. The sliding plate 501 can slide along the arrangement direction of each hanging branch assembly. The squeezing rollers 502 are mounted on the sliding plate 501 and can rotate around a vertical axis. The two squeezing rollers 502 are arranged at intervals, and the hanging branch assembly is located between the two squeezing rollers 502; the two squeezing rollers 502 are used to squeeze the hanging branch assembly to reduce the interval 103 thereof.

[0060] Specifically, when the sliding plate 501 slides along the length direction parallel to the crossbar 101, the two squeezing rollers 502 will squeeze each group of hanging branch components in turn. When the two hanging branch rods 102 of the hanging branch components are squeezed by the two squeezing rollers 502, the spacing 103 between the two hanging branch rods 102 will be reduced, so that the workpiece 2 slides off the hanging branch components, and finally the workpiece 2 is automatically hung down.

[0061] Optionally, the lower end of the branch hanging rod 102 is an inclined rod 1021, and the two inclined rods 1021 are arranged in a V shape. A positioning semi-ring 1022 is provided in the middle of the branch hanging rod 102, and the two positioning semi-rings 1022 are arranged in a circular ring shape. Correspondingly, an extrusion boss 5021 is provided at the position corresponding to the extrusion roller 502 and the inclined rod 1021; the two extrusion bosses 5021 are used to squeeze inward from the outside of the two inclined rods 1021 to reduce the spacing distance 103. A positioning arc groove 5022 is provided at the position corresponding to the extrusion roller 502 and the positioning semi-ring 1022; the two positioning semi-rings 1022 are located between the two positioning arc grooves 5022.

[0062] When the squeezing roller slides with the sliding plate 501, the positioning half ring 1022 falls into the corresponding positioning arc groove 5022 to ensure the relative positioning of the hanging branch rod 102 and the squeezing roller 502, and the squeezing boss 5021 squeezes the tilting rod 1021 to reduce the spacing distance 103 between the two tilting rods 1021.

[0063] It is understandable that the hanging space sizes of different workpieces 2 are different, and therefore, the required reduction amount of the spacing distance 103 between the two hanging branch rods 102 is also different. To this end, the extrusion assembly 5 provided in this embodiment also includes two adjustment plates 503. An adjustment plate 503 is provided between each of the extrusion rollers 502 and the sliding plate 501, and the adjustment plate 503 is provided with a strip through hole 5031 for fixing to the sliding plate 501, and the length direction of the strip through hole 5031 is parallel to the arrangement direction of the two extrusion rollers 502. Use a fixing bolt to pass through the strip through hole 5031 and then be threadedly connected to the sliding plate 501 to achieve relative fixation of the sliding plate 501 and the adjustment plate 503. If the required reduction amount of the spacing distance 103 between the two hanging branch rods 102 is large, the fixing bolts can be loosened first, the two adjustment plates 503 are brought closer to each other, and then the fixing bolts are tightened, at which time the distance between the two squeezing rollers 502 is reduced, so that the reduction amount of the spacing distance 103 between the two hanging branch rods 102 when squeezed is increased. Similarly, if the required reduction amount of the spacing distance 103 between the two hanging branch rods 102 is small, the fixing bolts can be loosened first, the two adjustment plates 503 are moved away from each other, and then the fixing bolts are tightened, at which time the distance between the two squeezing rollers 502 is increased, so that the reduction amount of the spacing distance 103 between the two hanging branch rods 102 when squeezed is reduced.

[0064] Generally, the linear reciprocating sliding of the sliding plate 501 can be realized by using a cylinder or a ball screw or other mechanism. In this embodiment, the extrusion assembly 5 includes a driving pulley 504, a driven pulley 505, a transmission belt, a motor 506, a guide rail 507 and a slider 508. The sliding plate 501 is located between the driving pulley 504 and the driven pulley 505. The two ends of the transmission belt are respectively connected to the driving pulley 504 and the driven pulley 505, and one end of the sliding plate 501 is fixedly connected to the transmission belt. The motor 506 is connected to the driving pulley 504 for driving the driving pulley 504 to rotate. The guide rail 507 is fixedly arranged relative to the fixed assembly, and its length direction is parallel to the length direction of the crossbar 101 fixed on the fixed assembly. One side of the slider 508 is connected to the guide rail 507 in a sliding manner, and the other side is fixedly connected to the other end of the sliding plate 501.

[0065] Specifically, when the motor 506 rotates forward, the transmission belt drives the sliding plate 501 to slide toward the first fixed seat 401. Conversely, when the motor 506 rotates reversely, the transmission belt drives the sliding plate 501 to slide toward the second fixed seat 402. The guide rail 507 and the slider 508 play a guiding role and can ensure the smoothness of the sliding plate 501 when sliding.

[0066] Optionally, the extrusion assembly 5 further includes two material baffles 509 , and the two extrusion rollers 502 are located between the two material baffles 509 , and are used to block the workpiece 2 sliding down from the hanging branch assembly, so as to prevent the workpiece 2 from splashing everywhere after being hung.

[0067] In this embodiment, a drawer-type receiving tray 6 is further provided below the frame 3. The drawer-type receiving tray 6 is located below the tension hanger 1 and is used to receive the workpiece 2 that slides off the hanging branch assembly. Fig.11 A pull-out handle 601 is fixedly connected to the side of the drawer-type material receiving tray 6 to facilitate the pull-out operation.

[0068] Optionally, the automatic hanging device further includes a photoelectric sensor, which is fixed to the side of the fixing component and is used to sense whether there are still workpieces 2 hanging on the tension hanger 1. It can be understood that the light emitted by the photoelectric sensor is parallel to the length direction of the crossbar 101 and is located below each hanging branch component. If there is a workpiece 2 that has not been hung, the light will be blocked. If the light is not blocked, it means that all workpieces 2 have been hung.

[0069] Optionally, a limit block may be provided on the sliding path of the sliding plate 501 to limit the sliding distance of the sliding plate 501 .

[0070] Optionally, this embodiment adopts a double hanging station structure to further improve the working efficiency of the hanging.

[0071] The working process of the automatic hanging device provided in this embodiment is as follows:

[0072] Place the tension hanger 1 with the workpiece 2 mounted thereon into the fixing assembly;

[0073] ① Click the start button, the motor 506 rotates, driving the sliding plate 501 to slide;

[0074] ② The squeezing roller 502 rolls each hanging branch assembly while sliding with the sliding plate 501, and reduces the interval 103 between the two hanging branch rods 102 of each hanging branch assembly one by one. After the interval 103 is reduced, the corresponding workpiece 2 will automatically fall into the drawer-type receiving tray 6 below; if any workpiece 2 splashes when hanging down, it will also be blocked by the blocking plate 509;

[0075] ③ The photoelectric sensor senses the workpiece 2. If there are any workpieces 2 that have not been hung, the motor 506 drives the sliding plate 501 to slide back and forth until all the workpieces 2 have been hung; the motor 506 drives the sliding plate 501 to reset;

[0076] ④ Pull out the drawer-type collecting tray 6 to complete the material collection.

[0077] The automatic hanging device provided in this embodiment uses the hanging branch assembly to hang the workpiece 2 through its own spacing distance 103 to prevent the workpiece 2 from sliding down. When hanging is required, the hanging mechanism is used to squeeze the two hanging branch rods 102 of the hanging branch assembly to reduce the spacing distance 103 between the two hanging branch rods 102. The entire process is completed automatically by mechanical equipment, the hanging speed is high, and the production efficiency is greatly improved.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
