Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and more specifically, to positioning devices and production lines. Background Technology

[0002] In some known production workshops, products are typically transported using lifting devices. However, these devices operate at relatively high speeds, and significant swaying can occur after they stop moving, especially at the free end. This makes it difficult to accurately position the devices during loading and unloading, resulting in a significant decrease in loading and unloading efficiency. Utility Model Content

[0003] This application provides a positioning device and a production line to solve the technical problem of low loading and unloading efficiency of hanging parts in some known technologies.

[0004] The embodiments of this application are implemented as follows: In a first aspect, this application provides a positioning device for a hanging component moving device. The hanging component moving device includes a mounting frame and a hanging component. The hanging component includes a moving end and a holding end. The moving end is movably disposed on the mounting frame, and the holding end extends in a direction away from the mounting frame. The holding end is used to hold a product. The positioning device includes a guiding component and a fixing component. The guiding component has a guiding groove that extends in a first direction and is used to guide the moving end to move in the first direction. The fixing component is correspondingly disposed to the guiding component along the extension direction of the hanging component. The fixing component includes a stop portion and a clamping portion. The stop portion and the clamping portion are spaced apart in a second direction. The stop portion is used to stop the holding end, and the clamping portion is used to clamp the holding end stopped by the stop portion.

[0005] According to the positioning device of this application, the guiding component can guide the movement of the hanging component, improve the movement accuracy of the hanging component, significantly reduce the swaying generated during the movement of the hanging component, and improve the holding stability of the product held at the holding end. The stop part first blocks the holding end to keep it relatively stationary, and then the clamping part quickly clamps the holding end, limiting its position. In this way, both the moving end and the holding end of the hanging component are reliably limited, thereby improving the overall stability of the hanging component during subsequent movement, significantly reducing the swaying amplitude of the product, improving the loading and unloading efficiency, and increasing the yield of the product loading and unloading.

[0006] In one possible implementation: The guide channel has an inlet and an outlet. Along the direction from the inlet to the outlet, the guide channel includes a guide section, the width of which gradually decreases in the direction approaching the outlet.

[0007] In one possible implementation: The guide groove has arc surfaces that are arranged opposite each other along a second direction, the arc surfaces protruding toward the inside of the guide groove, and the two arc surfaces are configured to contact the moving end line.

[0008] In one possible implementation: The guiding component includes two guide members, which are spaced apart along a first direction and form a guiding groove between them. The outer peripheral surface of each guide member is an arc surface.

[0009] In one possible implementation: The stop portion has a stop surface on one side along the first direction; the clamping portion is located on one side of the stop portion along the second direction, and the clamping portion includes two clamping blocks, which have an open position and a clamping position. In the open position, the clamping blocks are located on the side of the hanging end away from the moving end. In the clamping position, the two clamping blocks are spaced apart along the first direction and form a clamping groove; along the first direction, the stop surface is located between the two clamping blocks.

[0010] In one possible implementation: The fixing component also includes a magnetic suction part, which is disposed on the stop part and is used to attract the hanging end.

[0011] In one possible implementation: The positioning device further includes a moving component, which is connected to the fixed component and is used to drive the fixed component to reciprocate along a first direction.

[0012] Secondly, this application provides a production line including a hanging component moving device and the positioning device described above. The hanging component moving device includes a mounting frame and a hanging component. The hanging component includes a moving end and a holding end. The moving end is movably disposed on the mounting frame, and the holding end extends in a direction away from the mounting frame. The holding end is used to carry products.

[0013] In one possible implementation: The production line also includes a material handling device and a transport device. The material handling device is used to grab the product and transfer the product between the hanging device and the transport device.

[0014] In one possible implementation: The material handling device includes a drive assembly, a material handling section, and an adsorption section. The material handling section is driven by the drive assembly and is configured to reciprocate between the hanging component and the transport device under the drive of the drive assembly.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

When a component is said to be "set on" another component, it can be directly set on the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] For ease of description, this embodiment defines a first direction X, a second direction Y, and a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular or oblique to each other.

[0029] See Figure 1 This embodiment provides a production line 100, including a hanging component moving device 10 and a positioning device 20. The hanging component moving device 10 includes a mounting frame 11 and a hanging component 12. See also Figure 2 The hanging member 12 includes a movable end 121 and a holding end 122 spaced apart along its length. The movable end 121 is movably mounted on the mounting frame 11, and the holding end 122 extends in a direction away from the mounting frame 11 (third direction Z), and is used to carry the product 200. The movable end 121 can be moved along the mounting frame 11 by a hanging drive component (not shown). The extension direction of the mounting frame 11 can be curved, straight, or irregular. Multiple hanging members 12 can be provided, spaced apart from each other along the extension direction of the mounting frame 11. This increases the number of products 200 transported by the hanging member moving device 10.

[0030] In some embodiments, see Figure 2 and Figure 3The hanging component 12 includes a first rod 123, a second rod 124, a third rod 125, and a hanging part 126. One end of the first rod 123 is movably connected to the mounting frame 11. There are two second rods 124. One end of each of the two second rods 124 is connected to the end of the first rod 123 away from the mounting frame 11 via a third rod 125. The two second rods 124 extend in a third direction (Z) away from the mounting frame 11. There are multiple third rods 125, which are spaced apart between the two second rods 124 in the third direction (Z). One end of the hanging part 126 is connected to the third rod 125, and the other end of the hanging part 126 extends in a direction close to the mounting frame 11. The hanging part 126 and the second rods 124 are used to support and hang the product 200. The end of the first rod 123 away from the second rod 124 forms a movable end 121. The second rod 124 connects to one end of the hanging part 126 to form the hanging end 122.

[0031] In some embodiments, see Figure 1 and Figure 2 The positioning device 20 includes a guide assembly 21 and a fixing assembly 22. See also... Figure 3 The guide component 21 has a guide groove C1 that extends along the first direction X. The guide groove C1 is used to guide the mobile end 121 to move along the first direction X. See also Figure 4 and Figure 5 The fixing component 22 and the guiding component 21 are correspondingly arranged along the length direction of the hanging member 12. The fixing component 22 includes a stop part 221 and a clamping part 222. The stop part 221 and the clamping part 222 are spaced apart along the first direction X. The stop part 221 is used to stop the hanging end 122, and the clamping part 222 is used to clamp the hanging end 122 that is stopped by the stop part 221.

[0032] According to the positioning device 20 of this embodiment, the guiding component 21 can guide the movement of the hanging component 12, improve the movement accuracy of the hanging component 12, significantly reduce the swaying generated during the movement of the hanging component 12, and improve the holding stability of the product 200 held on the holding end 122. The stop part 221 first blocks the holding end 122 to keep the holding end 122 relatively stationary. Then, the clamping part 222 quickly clamps the holding end 122 and limits the holding end 122. In this way, both the moving end 121 and the holding end 122 of the hanging component 12 are reliably limited, thereby improving the overall stability of the hanging component 12 in the subsequent movement process, significantly reducing the swaying amplitude of the product 200, improving the loading and unloading efficiency of the product 200, and improving the loading and unloading yield of the product 200.

[0033] In some embodiments, see Figure 2The production line 100 also includes a picking device 30 and a transport device 40. The picking device 30 is used to pick up the product 200 and transfer the product 200 between the hanging member 12 and the transport device 40. Thus, after the current hanging end 122 of the hanging member 12 is clamped by the fixing component 22, as the moving end 121 of the hanging member 12 moves along the first direction X, the picking device 30 can transfer the product 200 between the hanging member 12 and the transport device 40.

[0034] The transport device 40 can be specifically configured as a belt conveyor line.

[0035] In some embodiments, see Figure 6 The material handling device 30 includes a drive assembly 31, a material handling section 32, and an adsorption section 33. The material handling section 32 is driven by the drive assembly 31 and is configured to reciprocate between the hanging member 12 and the transport device 40 under the drive of the drive assembly 31. The adsorption section 33 is connected to the material handling section 32 and is used to adsorb the product 200. Thus, the drive assembly 31 drives the material handling section 32 to approach the product 200 and adsorbs the product 200 through the adsorption section 33. The material handling section 32 first adsorbs the product 200 through the adsorption section 33, and then the drive assembly 31 places the product 200 on the hanging end 122 or the transport device 40. The adsorption section 33 can improve the connection stability between the product 200 and the material handling section 32 during the transfer process. The adsorption section 33 can be a vacuum suction cup or a magnetic suction component. Among them, the magnetic suction component can avoid the possibility that the surface of the product 200 is not parallel to the material handling section 32, thereby improving the transfer reliability of the product 200.

[0036] During the movement of the movable end 121 of the hanging component 12 along the first direction X, the driving component 31 drives the material picking part 32 to accelerate its movement to approach the hanging end 122.

[0037] Optionally, the drive component 31 can be configured as a multi-axis robot or a multi-slide moving mechanism.

[0038] Optionally, see Figure 2 The number of material handling devices 30 is two. The two material handling devices 30 are respectively located on both sides of the mounting frame 11 along the second direction Y. The hanging member 12 includes at least three third rods 125. The two lowest third rods 125 are respectively provided with hanging portions 126 on both sides along the first direction X. The two material handling devices 30 are used to transfer the product 200 located on the two third rods 125, or to place the product 200 on the two third rods 125. This improves the stability of the product 200 transfer cycle.

[0039] Optionally, the material handling section 32 can be configured as a cylinder. The material handling section 32 and the adsorption section 33 can be constructed as a single magnetic cylinder.

[0040] In some embodiments, see reference Figure 3The guide channel C1 has an inlet C11 and an outlet C12. Along the direction from the inlet C11 to the outlet C12, the guide channel C1 includes a guide section C13, the width of which gradually decreases towards the outlet C12. Thus, the guide section C13 guides the hanging component 12, ensuring that it enters the inlet C11 during movement.

[0041] Optionally, see Figure 3 The mounting bracket 11 includes a first mounting section 111 and a second mounting section 112. The first mounting section 111 and the second mounting section 112 are connected at an angle. The second mounting section 112 extends along a first direction X. A guide assembly 21 is disposed on the second mounting section 112. One end of the guide assembly 21 extends to one side of the first mounting section 111 along a second direction Y. Thus, during the movement of the hanging member 12 from the first mounting section 111 to the second mounting section 112, it can enter the guide section C13, which has a wider width, thereby changing the movement direction of the hanging member 12 and moving the hanging member 12 into the guide groove C1.

[0042] In some embodiments, see Figure 3 The guide groove C1 has two arc surfaces P1 arranged opposite each other along the second direction Y. The arc surfaces P1 protrude towards the inside of the guide groove C1, and the two arc surfaces P1 are configured to make line contact with the moving end 121. In this way, the friction between the guide groove C1 and the moving end 121 can be reduced, thereby ensuring both the reliability and accuracy of the movement of the moving end 121.

[0043] In some embodiments, see Figure 3 The guide component 21 includes two guide members 211. The two guide members 211 are spaced apart along the first direction X, and a guide groove C1 is formed between the two guide members 211. The outer peripheral surface of the guide member 211 is an arc surface P1.

[0044] Optionally, the guide 211 includes a guide tube. The outer circumferential surface of the guide tube can be formed as an arc surface. The shape of the guide groove C1 can also be easily formed by bending the guide tube. In this way, the processing cost of the guide 211 can be reduced.

[0045] In some embodiments, see Figure 3 The guide assembly 21 also includes a connector 212 and two mounting members 213. One end of the connector 212 is connected to the mounting bracket 11. The two mounting members 213 are connected to the other end of the connector 212 at intervals along the second direction Y. The two guide members 211 are respectively connected to the opposite sides of the two mounting members 213. In this way, the installation reliability of the guide members 211 can be improved.

[0046] Optionally, see Figure 3The connector 212 includes a first connecting plate 2121, a second connecting plate 2122, and a third connecting plate 2123. The first connecting plate 2121 connects to the mounting bracket 11. The second connecting plate 2122 and the third connecting plate 2123 are respectively connected to the two ends of the first connecting plate 2121 along the second direction Y. Both the second connecting plate 2122 and the third connecting plate 2123 extend towards the guide member 211 along the third direction Z. One mounting member 213 connects to the end of the second connecting plate 2122 opposite to the first connecting plate 2121, and the other mounting member 213 connects to the end of the third connecting plate 2123 opposite to the first connecting plate 2121.

[0047] Optionally, there are multiple connectors 212. The multiple connectors 212 are spaced apart along a first direction X. The mounting member 213 includes a mounting strip. The mounting strip extends along the first direction X.

[0048] In some embodiments, see Figure 4 and Figure 5 The positioning device 20 also includes a moving component 23. The moving component 23 is connected to the fixed component 22 and is used to drive the fixed component 22 to reciprocate along the first direction X.

[0049] Specifically, the fixing component 22 has a first position and a second position. In the first position, the fixing component 22 corresponds to the inlet C11 of the guide groove C1 along the first direction X along the third direction Z. In the second position, the fixing component 22 corresponds to the outlet C12 of the guide groove C1 along the first direction X along the third direction Z. When the hanging component 12 is about to reach the inlet C11 of the guide groove C1, the moving component 23 drives the fixing component 22 to move to the first position. Afterward, the fixing component 22 fixes the holding end 122. During the movement of the moving end 121 of the hanging component 12, the moving component 23 drives the fixing component 22 to move the holding end 122 along the first direction X, thereby further improving the movement stability of the hanging component 12. During the process of the moving component 23 driving the fixing component 22 from the first position to the second position, the material handling part 32 accelerates towards the holding end 122 under the drive of the driving component 31 to realize the transfer of the product 200.

[0050] In other embodiments, the positioning device 20 may be provided with a guide slide. The fixing component 22 is movably disposed on the guide slide. The guide slide can restrict the movement of the fixing component 22 along the first direction X, and can also improve the movement stability of the hanging component 12.

[0051] In some embodiments, see Figure 7The moving component 23 includes a moving slide 231 and a support plate 232. The moving slide 231 is drivenly connected to the support plate 232 to drive the support plate 232 to reciprocate along the first direction X. The fixed component 22 is disposed on the support plate 232. The moving slide 231 may be an electric slide or other types of drive mechanism.

[0052] In some embodiments, see Figure 4 and Figure 5 The stop portion 221 has a stop surface P2 on one side along the first direction X; the clamping portion 222 is located on one side of the stop portion 221 along the second direction Y, and includes two clamping blocks 2221. The two clamping blocks 2221 have an open position and a clamping position. In the open position, the clamping blocks 2221 are located on the side of the hanging end 122 opposite to the moving end 121. In the clamping position, the two clamping blocks 2221 are spaced apart along the first direction X and form a clamping groove C2. Along the first direction X, the stop surface P2 is located between the two clamping blocks 2221.

[0053] Thus, before the stop portion 221 stops the holding end 122, the two clamping blocks 2221 are in the open position, which can prevent the clamping blocks 2221 from limiting the movement of the holding end 122, ensuring that the holding end 122 can move to abut the stop surface P2. After the stop surface P2 stops the holding end 122, the two clamping blocks 2221 switch to the clamping position and clamp the holding end 122 in the clamping groove C2, realizing reliable clamping of the holding end 122. In addition, the stop surface P2 is located between the two clamping blocks 2221 along the first direction X, which can also prevent the two clamping blocks 2221 from causing the holding end 122 to shake during the clamping process, thereby improving the fixed reliability of the holding end 122.

[0054] In some embodiments, see Figure 4 and Figure 5 The fixing component 22 also includes a magnetic suction part 223. The magnetic suction part 223 is provided on the stop part 221 and is used to attract the hanging end 122. Some known hanging components 12 are made of a metal that can be magnetically attracted. In this way, the magnetic suction part 223 can apply a magnetic force to the hanging end 122, so that the hanging end 122 is blocked quickly and efficiently.

[0055] Specifically, the magnetic attraction part 223 forms a stop surface P2 on the side opposite to the stop part 221. The magnetic attraction part 223 can be constructed as a permanent magnet or an electromagnet.

[0056] In some embodiments, see Figure 4 and Figure 5The fixing assembly 22 also includes a first driving member 224 and a second driving member 225. The first driving member 224 is drivenly connected to two clamping blocks 2221 to move the two clamping blocks 2221 between a clamping position and an open position. The second driving member 225 is drivenly connected to a stop part 221 to move the stop part 221 along the third direction Z.

[0057] In some embodiments, see Figure 5 The clamping part 222 also includes two connecting arms 2222. One end of each connecting arm 2222 is connected to a first driving member 224, and the other end is connected to two clamping blocks 2221 respectively. Thus, the first driving member 224 can drive the two connecting arms 2222 to rotate, thereby moving the two clamping blocks 2221 away from the hanging end 122 to release the hanging end 122 without affecting the movement of the hanging member 12. The first driving member 224 can also drive the two connecting arms 2222 to rotate, causing the two clamping blocks 2221 to move closer together to clamp the hanging end 122, thereby fixing the hanging end 122.

[0058] The working process of the fixing component 22 in this embodiment is as follows.

[0059] Before the hanging member 12 moves to the position corresponding to the opening, the first drive member 224 drives the two clamping blocks 2221 to remain in the open position. The second drive member 225 drives the stop part 221 to remain at a position spaced apart from the hanging end 122 along the third direction Z. When the hanging member 12 moves to the position corresponding to the opening, the second drive member 225 drives the stop part 221 to move closer to the mounting frame 11 along the third direction Z, so that the stop part 221 stops the hanging end 122. The first drive member 224 drives the two clamping blocks 2221 to switch to the clamping position and clamp the hanging end 122. After the hanging member 12 moves to the position corresponding to the outlet C12, the first drive member 224 drives the two clamping blocks 2221 to switch to the open position, and the second drive member 225 drives the stop part 221 to move away from the mounting frame 11 along the third direction Z, thereby releasing the hanging end 122 so that the hanging member 12 can continue to move along the mounting frame 11.

[0060] In some embodiments, see Figure 3 The positioning device 20 also includes a sensor 24. The sensor 24 is connected to the fixing frame. The sensor 24 is used to detect the positional relationship between the hanging part 12 and the inlet C11, and after the hanging part 12 reaches the position corresponding to the fixing component 22 along the third direction Z, it controls the first driving member 224 and the second driving member 225 to operate, so as to fix the hanging end 122.

[0061] Sensor 24 can be an infrared sensor or a camera, etc. An infrared sensor can determine whether the hanging part 12 is about to enter the guide groove C1 by measuring the distance between the hanging part 12 and the opening. A camera can determine whether the hanging part 12 is about to enter the guide groove C1 by measuring the image size of the hanging part 12. The specific detection method of sensor 24 will not be described in detail here.

[0062] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
