Description

Technical Field

[0001] This invention relates to the field of metal product processing technology, and in particular to an automatic feeding device for metal product processing. Background Technology

[0002] In intelligent welding systems for metal products, automated clamping and feeding systems are typically used to automate the loading of metal products, reducing manual labor. However, current automated clamping and feeding devices generally have a limitation: they can often only clamp a single metal product at a time. When dealing with large volumes of metal products, this means frequent clamping and feeding operations are required, significantly impacting the convenience of the workflow. While adding multiple feeding devices for parallel processing could theoretically improve efficiency, this inevitably requires a corresponding number of drive units, leading to a sharp increase in feeding costs. Even more problematic is the potential for mechanical vibration during metal product transfer. It could cause slight loosening of the clamping components, increasing the risk of metal products falling off. Such falls not only disrupt production but can also damage the metal products, severely impacting product quality and production safety.

[0003] To address the aforementioned problems, this invention proposes an automatic feeding device for metal product processing. Summary of the Invention

[0004] The purpose of this invention is to address the problem that current automatic clamping and feeding devices in the technical field can only clamp a single metal product at a time, which greatly affects the convenience of the operation process when dealing with the need to process a large number of metal products. If multiple feeding devices are added for parallel processing, the cost of feeding operations will increase dramatically. More problematic is the drawback that mechanical vibration during the transfer of metal products may increase the risk of metal products falling off. Therefore, this invention proposes an automatic feeding device for metal product processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic feeding device for metal product processing includes a robotic arm device, wherein the robotic arm device is equipped with a material gripping mechanism;

[0007] The material gripping mechanism includes a mounting shell and an adjustable clamping drive assembly. The mounting shell is fixedly mounted on the robotic arm device. An arc-shaped block and an inner cylinder are fixedly connected inside the mounting shell. The inner cylinder is located in the middle of the mounting shell, and an arc-shaped notch is opened on one side of the inner cylinder. The mounting shell also has a transmission assembly inside, and multiple pushing components are mounted on the transmission assembly.

[0008] The bottom of the pushing component is connected to a material gripping component. The tops of multiple pushing components rotate and move onto the arc-shaped block, thereby squeezing the pushing component to move downward, causing one of the material gripping components to move downward, so that the adjustable clamping drive component can smoothly drive downward with the material gripping component. The other end of the material gripping component is connected to a second toothed disc, which is locked with a locking component. One end of the locking component is rotated to be located at the notch, so that the locking component is reset and disengaged from the second toothed disc.

[0009] The adjustable clamping drive assembly includes a first gear and a three-lobe shaft. Three positioning plates are fixedly connected inside the first gear, and second springs are fixedly connected to the positioning plates. One end of each of the three second springs is fixedly connected to one of the three fins of the three-lobe shaft. A switch corresponding to the adjustable trigger structure is installed on the three-lobe shaft, and the adjustable trigger structure is connected to the positioning plates.

[0010] Preferably, the adjustable clamping drive assembly further includes a mounting bracket, which is fixedly connected to one side of the mounting housing. An electric push rod is fixedly mounted on the mounting bracket, and a motor is fixedly mounted at the bottom end of the electric push rod. The output shaft of the motor is fixedly connected to a three-lobe shaft, which is located in the first gear.

[0011] Preferably, the first gear has three grooves inside, and a slider is slidably connected in the groove. The slider is fixedly connected to the fin of the three-lobe shaft.

[0012] Preferably, the adjustable trigger structure includes an outer cylinder, which is fixedly connected to one of the positioning plates, and an adjusting rod is slidably provided inside the outer cylinder, which is fixed in the outer cylinder by bolts.

[0013] Preferably, the transmission assembly includes a turntable, a transmission gear ring is fixedly connected to the lower part of the turntable, and an upper ring plate is fixedly connected to the upper part of the turntable. The upper ring plate is rotatably mounted in the mounting housing via bearings.

[0014] Preferably, the pushing assembly includes a sliding sleeve, which is fixedly mounted on a turntable. A sliding rod is slidably connected inside the sliding sleeve. A first pulley is fixedly connected to the top end of the sliding rod. A first spring is fixedly connected to the bottom of the first pulley. The bottom end of the first spring is fixedly connected to the top of the sliding sleeve.

[0015] Preferably, the material gripping assembly includes a support frame and a bidirectional screw. The upper part of the support frame is fixedly connected to a slide rod, and the bidirectional screw is rotatably mounted on the support frame through two bearings. The two ends of the bidirectional screw are respectively fixedly connected to a second gear and a second chuck disc.

[0016] Preferably, the threads on both sides of the bidirectional screw are arranged in opposite directions, and two transmission nuts are threadedly connected to the bidirectional screw. A clamping plate is fixedly installed on the transmission nut, and a guide block is fixedly connected above the clamping plate. The guide block slides in the guide opening, which is opened on the support frame.

[0017] Preferably, the locking assembly includes a first toothed disc, which is adapted to a second toothed disc. A connecting rod is fixedly connected to one side of the first toothed disc, and a second pulley is fixedly connected to one end of the connecting rod. The second pulley overlaps with the inner cylinder.

[0018] Preferably, a telescopic rod and a third spring are fixedly connected to the other side of the first toothed disc, and an installation component is fixedly connected to one end of the telescopic rod and the third spring, and the installation component is fixedly connected to the support frame.

[0019] Compared with the prior art, the present invention provides an automatic feeding device for metal product processing, which has the following beneficial effects:

[0020] 1. This automatic feeding device for metal product processing utilizes an adjustable clamping drive assembly and a transmission assembly. The transmission assembly drives the gripping assembly in a circular motion. When the pushing assembly moves onto the arc-shaped block, it pushes down the gripping assembly. The adjustable clamping drive assembly allows for adjustment of the clamping force of the clamping plates to meet different clamping requirements. The downward movement of the adjustable clamping drive assembly and the transmission of the gripping assembly enable the gripping assembly to complete the clamping of metal products. After clamping, the gripping assembly rotates again to change its position, thus clamping and positioning multiple metal products. This method can complete the automatic gripping of multiple metal products in a single operation, reducing the movement cycle of the robotic arm and improving feeding efficiency. It also provides convenience for intelligent welding systems for metal products.

[0021] 2. This automatic feeding device for metal product processing drives the transmission component to rotate through an adjustable clamping drive component, which in turn drives the gripping component to rotate. When the second pulley moves out of the arc surface of the arc notch, the arc surface of the arc notch presses the second pulley to move. The second pulley drives the first toothed disc to lock with the second toothed disc, thereby locking the gripping component and ensuring the gripping component firmly holds the metal product, thus preventing the metal product from falling off.

[0022] 3. This automatic feeding device for metal product processing uses an adjustable clamping drive assembly to drive a transmission assembly to rotate. The transmission assembly drives the pushing assembly and the gripping assembly to rotate. Simultaneously, the locking assembly moves to the arc-shaped notch position, allowing it to reset and disengage from the second toothed disc. When the pushing assembly moves to the arc surface of the arc block, it is pressed down on the gripping assembly. At this point, the adjustable clamping drive assembly moves downward, engaging with the gripping assembly to achieve automatic gripping. After gripping, the gripping assembly rotates to switch positions, allowing for further rotation. The device performs reciprocating material gripping operations. After gripping, the material disengages from the arc-shaped notch via a locking component. The locking component then engages with the second toothed disc to automatically position the gripping component, ensuring secure clamping. This method utilizes an adjustable clamping drive component that switches between the transmission and gripping components, enabling the clamping of metal products, locking of the gripping component, switching of gripping component locking, and multiple clamping operations at once. This effectively optimizes the entire feeding process, improves operational convenience, and features a simple structure and low cost. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0036] Example 1: Refer to Figures 1-8 and Figure 10 An automatic feeding device for metal product processing includes a robotic arm 100, on which a gripping mechanism 200 is provided;

[0037] The material gripping mechanism 200 includes a mounting shell 203 and an adjustable clamping drive assembly 207. The adjustable trigger structure 2076 includes an outer cylinder 20761, which is fixedly connected to one of the positioning plates 2077. An adjusting rod 20762 is slidably provided inside the outer cylinder 20761 and is fixed in the outer cylinder 20761 by bolts. The adjusting rod 20762 can slide and adjust its position in the outer cylinder 20761, thereby adjusting the distance between the switch 2075 and the adjusting rod 20762. This allows the adjusting rod 20762 to press the switch 2075 at different positions to control the motor 2074, thereby adjusting the clamping force of the clamping plate 2055. The size is adjusted to meet the clamping requirements in different situations. The position of the adjusting rod 20762 can be fixed with bolts to prevent it from loosening. The mounting shell 203 is fixedly installed on the robotic arm device 100. The flexibility of the robotic arm device 100 facilitates the loading of metal products. An arc-shaped block 209 and an inner cylinder 202 are fixedly connected inside the mounting shell 203. The inner cylinder 202 is located in the middle of the mounting shell 203, and an arc-shaped notch 204 is opened on one side of the inner cylinder 202. A transmission assembly 201 is also provided inside the mounting shell 203. The transmission assembly 201 includes a turntable 2011, and a transmission gear ring is fixedly connected below the turntable 2011. 2012, an upper ring plate 2013 is fixedly connected above the turntable 2011. The upper ring plate 2013 is rotatably mounted in the mounting housing 203 via bearings. The upper ring plate 2013 can maintain stable rotation through the bearings, thereby ensuring stable rotation of the turntable 2011 and the transmission gear ring 2012. Multiple pushing components 206 are mounted on the transmission assembly 201. Each pushing component 206 includes a sliding sleeve 2061, which is fixedly mounted on the turntable 2011. A sliding rod 2063 is slidably connected inside the sliding sleeve 2061. The sliding sleeve 2061 guides the sliding rod 2063, allowing it to slide smoothly within the sliding sleeve 2061. The top end of the sliding rod 2063 is fixedly connected to... A first pulley 2064 is provided. The pulley 2064 moves to the arc surface of the arc block 209. As the arc curvature of the arc block 209 increases, the second pulley 2086 is squeezed by the arc surface of the arc block 209, which drives the slide rod 2063 to move downward. The slide rod 2063 can drive the material gripping assembly 205 to move downward. A first spring 2062 is fixedly connected to the lower part of the first pulley 2064. When the first pulley 2064 separates from the arc block 209, the first spring 2062 drives the first pulley 2064 to reset. The slide rod 2063 drives the material gripping assembly 205 to reset smoothly upward. The bottom end of the first spring 2062 is fixedly connected to the upper part of the sliding sleeve 2061.

[0038] The bottom of the pushing assembly 206 is connected to a gripping assembly 205, which includes a support frame 2051 and a bidirectional screw 2052. The upper part of the support frame 2051 is fixedly connected to the slide rod 2063. The bidirectional screw 2052 is rotatably mounted on the support frame 2051 via two bearings. The bidirectional screw 2052 can rotate smoothly through the bearings, enabling threaded transmission between the bidirectional screw 2052 and the transmission nuts 2053. The relative movement of the two transmission nuts 2053 can drive the two clamping plates 2055 to clamp and fix the metal product. The two ends of the bidirectional screw 2052 are fixedly connected to the second gear 2057 and the second gear disc 210, respectively. The threads on both sides of the bidirectional screw 2052 are arranged in opposite directions. By having two opposite threads on the bidirectional screw 2052, the rotation of the bidirectional screw 2052 can drive the two transmission nuts 2053 to move away from and towards each other, thereby facilitating the clamping and removal of the metal product. The threads on the bidirectional screw 2052 are connected to... Two transmission nuts 2053 are connected, and a clamping plate 2055 is fixedly installed on the transmission nuts 2053. A guide block 2056 is fixedly connected above the clamping plate 2055. The guide block 2056 slides in the guide opening 2054. The guide opening 2054 guides the guide block 2056, allowing it to slide smoothly along the guide opening 2054, thereby keeping the clamping plate 2055 moving smoothly. The guide opening 2054 is opened on the support frame 2051, and the top of the multiple pushing components 206 The part rotates and moves onto the arc block 209, thereby realizing the downward movement of the extrusion and pushing component 206, causing one of the gripping components 205 to move downward, so that the adjustable clamping drive component 207 can smoothly drive downward with the gripping component 205. The other end of the gripping component 205 is connected to the second toothed disc 210, which is locked with the locking component 208. One end of the locking component 208 is rotated to be located at the notch, so that the locking component 208 is reset and disengaged from the second toothed disc 210.

[0039] The adjustable clamping drive assembly 207 includes a first gear 2072 and a three-lobe shaft 2078. The three-lobe shaft 2078 has three fins that correspond to the positioning plates 2077, allowing the fins to smoothly connect to the positioning plates 2077 via a second spring 20711. Three positioning plates 2077 are fixedly connected inside the first gear 2072, and the second spring 20711 is fixedly connected to each positioning plate 2077. The second spring 20711 maintains the position of the three-lobe shaft 2078 and prevents it from clamping. 8. Rotation directly drives switch 2075 to contact adjusting rod 20762. Furthermore, when clamping metal products with clamping plate 2055, continuous force is applied, causing the second spring 20711 to deform, thereby increasing the applied force and maintaining the clamping stability of clamping plate 2055 until adjusting rod 20762 contacts switch 2075, stopping motor 2074. One end of each of the three second springs 20711 is fixedly connected to one of the three fins of the three-lobe shaft 2078. The three-lobe shaft 2078 is equipped with... Adjusting the switch 2075 corresponding to the adjustable trigger structure 2076 allows the adjustable trigger structure 2076 to connect with the positioning plate 2077. The adjustable clamping drive assembly 207 also includes a mounting bracket 2071, which is fixedly connected to one side of the mounting housing 203. An electric push rod 2073 is fixedly mounted on the mounting bracket 2071. The electric push rod 2073 drives the motor 2074 to move up and down, allowing the first gear 2072 to switch between transmission gear ring 2012 and the second gear 2057 for transmission. A motor 2074 is fixedly installed at the bottom of the push rod 2073. The output shaft of the motor 2074 is fixedly connected to the three-lobe shaft 2078. The three-lobe shaft 2078 is located in the first gear 2072. The first gear 2072 has three sliding grooves 20710 inside. A slider 2079 is slidably connected in the sliding grooves 20710. The slider 2079 can slide in the sliding grooves 20710, so that the three-lobe shaft 2078 can rotate smoothly. The slider 2079 is fixedly connected to the fins of the three-lobe shaft 2078.

[0040] In this embodiment: the motor 2074 drives the three-lobe shaft 2078 to rotate. The three-lobe shaft 2078 drives the first gear 2072 to rotate via the second spring 20711 and the positioning plate 2077. The first gear 2072 drives the transmission gear ring 2012, which in turn drives the turntable 2011 to rotate. The turntable 2011 drives the material gripping assembly 205 to move in a circular motion via the pushing assembly 206. When the first pulley 2064 moves onto the arc block 209, the arc block 209 moves by pressing the first pulley 2064. The first pulley 2064 drives the sliding rod 2063 to move downward. The sliding rod 2063 pushes down the material gripping assembly 205, and then the electric push rod 2073 pushes down the electric... Machine 2074 causes the first gear 2072 to mesh downwards with the second gear 2057, which in turn drives the bidirectional screw 2052 to rotate. The bidirectional screw 2052 drives the two transmission nuts 2053 to move closer together, which in turn brings the two clamping plates 2055 closer together, thus achieving the purpose of clamping the metal products. After clamping, the adjustable clamping drive assembly 207 moves upwards again to drive the transmission gear ring 2012, which in turn causes the gripping assembly 205 to rotate and change position again, thereby clamping and positioning multiple metal products. This method can complete the automatic gripping operation of multiple metal products in a single operation, reducing the movement cycle of the robot 100, thereby improving the feeding efficiency.

[0041] Example 2: Refer to Figures 5-6 and Figures 8-9An automatic feeding device for metal product processing includes a locking assembly 208, which includes a first toothed disc 2084 and a second toothed disc 210. A connecting rod 2085 is fixedly connected to one side of the first toothed disc 2084, and a second pulley 2086 is fixedly connected to one end of the connecting rod 2085. The second pulley 2086 rotates with the material gripping assembly 205, causing it to be positioned at an arc-shaped notch 204. This allows the elastic potential energy of the third spring 2082 to be released smoothly. Simultaneously, when the second pulley 2086 moves to the arc surface of the arc-shaped notch 204, the arc surface of the arc-shaped notch compresses the second pulley 2086, causing the first toothed disc 2084 to move, thus releasing the elastic potential energy of the third spring 2082. The first toothed disc 2084 and the second toothed disc 210 are locked together, thereby locking the material gripping component 205 and ensuring the firmness of the material gripping component 205. The second pulley 2086 overlaps with the inner cylinder 202. The other side of the first toothed disc 2084 is fixedly connected to the telescopic rod 2081 and the third spring 2082. The third spring 2082 drives the first toothed disc 2084 to reset, so that the first toothed disc 2084 and the second toothed disc 210 are separated. Thus, after the first gear 2072 and the second gear 2057 are driven, they can smoothly drive the bidirectional screw 2052 to rotate. One end of the telescopic rod 2081 and the third spring 2082 is fixedly connected to the mounting part 2083, and the mounting part 2083 is fixedly connected to the support frame 2051.

[0042] The transmission assembly 201 includes a turntable 2011, a transmission gear ring 2012 fixedly connected to the lower part of the turntable 2011, and an upper ring plate 2013 fixedly connected to the upper part of the turntable 2011. The upper ring plate 2013 is rotatably mounted in the mounting housing 203 via bearings.

[0043] The adjustable clamping drive assembly 207 includes a first gear 2072 and a three-lobe shaft 2078. Three positioning plates 2077 are fixedly connected inside the first gear 2072. Second springs 20711 are fixedly connected to the positioning plates 2077. One end of each of the three second springs 20711 is fixedly connected to one of the three fins of the three-lobe shaft 2078. A switch 2075 corresponding to the adjustable trigger structure 2076 is installed on the three-lobe shaft 2078. The adjustable trigger structure 2076 is connected to the positioning plates 2077. The adjustable clamping drive assembly 207 also includes a mounting bracket 2071. The mounting bracket 2071 is fixedly connected to one side of the mounting housing 203. An electric push rod 2073 is fixedly installed on the mounting bracket 2071. A motor 2074 is fixedly installed at the bottom end of the electric push rod 2073. The output shaft of the motor 2074 is fixedly connected to the three-lobe shaft 2078, which is located in the first gear 2072.

[0044] In this embodiment: the motor 2074 drives the three-lobe shaft 2078 to rotate. The three-lobe shaft 2078 can drive the first gear 2072 to rotate through the second spring 20711 and the positioning plate 2077. The first gear 2072 drives the transmission gear ring 2012, so that the transmission gear ring 2012 drives the pushing component 206 and the gripping component 205 to rotate through the turntable 2011. At the same time, the locking component 208 moves with the gripping component 205. When the second pulley 2086 moves out from the arc surface of the arc notch 204, the arc surface of the arc notch 204 squeezes the second pulley 2086 to move. The second pulley 2086 drives the first clamping plate 2084 to lock with the second clamping plate 210, so that the locking component 208 can lock the gripping component 205, ensuring the firmness of the gripping component 205 in clamping the metal product, thereby preventing the metal product from falling off.

[0045] Example 3: Reference Figures 3-5 and Figure 8 An automatic feeding device for metal product processing includes a gripping mechanism 200. The gripping mechanism 200 includes a mounting shell 203 and an adjustable clamping drive assembly 207. The mounting shell 203 is fixedly mounted on a robotic arm device 100. An arc-shaped block 209 and an inner cylinder 202 are fixedly connected inside the mounting shell 203. The inner cylinder 202 is located in the middle of the mounting shell 203, and an arc-shaped notch 204 is opened on one side of the inner cylinder 202. A transmission assembly 201 is also provided inside the mounting shell 203. Multiple pushing assemblies 206 are passed through the transmission assembly 201.

[0046] The bottom of the pushing component 206 is connected to the gripping component 205. The tops of multiple pushing components 206 rotate and move onto the arc block 209, thereby squeezing the pushing component 206 downward, causing one of the gripping components 205 to move downward, so that the adjustable clamping drive component 207 can smoothly drive downward with the gripping component 205. The other end of the gripping component 205 is connected to the second toothed disc 210. The second toothed disc 210 is locked with the locking component 208. One end of the locking component 208 is rotated to be located at the notch, so that the locking component 208 is reset and disengaged from the second toothed disc 210.

[0047] In this embodiment: the adjustable clamping drive assembly 207 drives the transmission assembly 201 to rotate, which in turn drives the pushing assembly 206 and the gripping assembly 205 to rotate. Simultaneously, the locking assembly 208 moves to the arc-shaped notch 204, allowing it to reset and disengage from the second toothed disc 210. When the pushing assembly 206 moves to the arc surface of the arc block 209, it is compressed and pushes down on the gripping assembly 205. At this time, the adjustable clamping drive assembly 207 moves downwards to engage with the gripping assembly 205, achieving automatic gripping. After gripping, the gripping assembly 205 rotates to continue switching positions. It can then be switched to perform reciprocating material gripping operations. After gripping, it disengages from the arc-shaped notch 204 through the locking component 208. The locking component 208 can then lock with the second toothed disc 210 to automatically position the gripping component 205 and maintain the reliability of the clamping. This method uses the adjustable clamping drive component 207 to switch the transmission between the transmission component 201 and the gripping component 205, thereby achieving the purpose of clamping metal products, locking the gripping component 205, switching the gripping component 205 to lock, and achieving multiple clamping at once. This can effectively optimize the entire feeding process, improve the convenience of the operation process, and has a simple structure and low cost.

[0048] Working principle: When feeding metal products, the motor 2074 drives the three-lobe shaft 2078 to rotate. The three-lobe shaft 2078 drives the first gear 2072 to rotate through the second spring 20711 and the positioning plate 2077. The first gear 2072 drives the transmission gear ring 2012, which in turn drives the turntable 2011 to rotate. The turntable 2011 drives the pushing component 206 and the gripping component 205 to rotate, causing the gripping component 205 to drive the locking component 208 to rotate. When the second pulley 2071... 86 moves to the position of the arc-shaped notch 204. At this time, the third spring 2082 drives the first toothed disc 2084 to reset, so that the first toothed disc 2084 separates from the second toothed disc 210. When the first pulley 2064 moves to the arc surface block 209, the arc surface of the arc surface block 209 presses the first pulley 2064 to move. The first pulley 2064 drives the first spring 2062 to deform. The first pulley 2064 drives the slide rod 2063 to move downward, so that the slide rod 2063 drives the material gripping assembly 205 to move downward.

[0049] Then, the electric push rod 2073 is extended, causing it to drive the motor 2074 downwards. This causes the first gear 2072 to follow the motor 2074 downwards, simultaneously meshing with the second gear 2057. The motor 2074 then drives the first gear 2072 to rotate, causing the second gear 2057 to drive the double-acting screw 2052 to rotate. The double-acting screw 2052 drives the two transmission nuts 2053 to move closer together, causing the transmission nuts 2053 to move the clamping plates 2055. The two clamping plates 2055 then clamp the metal product. After clamping, the electric push rod 2073 drives the motor 2074 to return to its original position, causing the first gear 2072 to mesh upwards with the transmission gear ring 2012. When the first gear 2072 engages with the transmission gear ring 2012 again, it causes the gripping assembly 205 and the pushing assembly 206 to move. This causes the second pulley 2086 to be squeezed by the arc notch 204, which can drive the first clamping disc 2084 to move. The first clamping disc 2084 locks with the second clamping disc 210. At the same time, the first spring 2062 drives the slide rod 2063 to reset upward, so that the gripping assembly 205 completes the reset. The gripping assembly 205 rotates to change its position, thus performing reciprocating clamping operations. After clamping, the metal product is transferred to the processing area by the robot arm device 100. Then, the adjustable clamping drive assembly 207 drives the gripping assembly 205 in the opposite direction, so that the gripping assembly 205 can smoothly perform the unloading operation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
