Description

Technical Field

[0001] This invention relates to the field of material handling fixtures, specifically a material handling fixture for automotive parts. Background Technology

[0002] The manufacturing of electric vehicles and other motor vehicles refers to the entire process of integrating and assembling core components such as power systems, chassis, body, and electrical equipment into a complete vehicle. With the advancement of the new energy and intelligent wave, this field is undergoing profound changes in terms of processes, layout, and technological collaboration. In the field of auto parts, various models of auto parts are produced by injection molding or stamping. After production, the auto parts need to be removed from the mold. However, thin-shell parts are not easy to grip. If a clamp is used to make hard contact with the part, it will also cause scratches on the shell surface and affect the quality.

[0003] Publication No. CN218560360U discloses a material handling fixture for automotive parts. It uses a suction cup to adhere to the inside of the automotive parts, thus removing them from the mold. A mounting base is connected to an external movable mechanism, which drives the material handling fixture to move closer to or further away from the automotive parts. The suction cup is connected to an external negative pressure system, which draws gas to create negative pressure at the suction port, generating suction to pick up the automotive parts. This replaces the existing method of manually removing automotive parts. The external movable mechanism drives the material handling fixture to pick up the parts, improving operational efficiency and reducing the occurrence of parts falling off. However, this patent still has the following problems in practical use: Although the material handling fixture for automotive parts can use a suction cup to pick up automotive parts from the mold, after the injection molding or stamping process, there will be some flash or debris inside the parts. This can cause air leakage when the suction cup is used for picking up the parts, and there is a risk that the parts will fall off during the picking process. At the same time, the debris may scratch the inner wall of the parts, thus affecting the molding quality of the parts.

[0004] Therefore, a material handling fixture for automotive parts is proposed to solve the problems mentioned above. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This material handling clamp for automotive parts utilizes the wave characteristics of a wave-shaped airbag to achieve the elongation of the wave-shaped airbag. Simultaneously, when gas enters the airbag clamp plate at the end of the wave-shaped airbag, it causes the airbag clamp plate to expand, allowing it to fit against the inner wall of the automotive part, increasing the contact area and thus improving the clamping support force. At the same time, gas enters the flipping airbags on both sides of the airbag clamp plate, causing the flipping airbags to expand and flip. Under the action of the flipping airbags, they can fit and connect against both sides of the suction cup bracket, sealing both sides of the suction cup bracket. Simultaneously, the annular airbag expands after being injected with gas, sealing the top and bottom of the suction cup bracket, creating a relatively closed space between the suction cup bracket and the inner wall of the automotive part. This, combined with the suction cup, enhances the suction force of the suction cup. The soft clamping of the automotive part through the airbag internal support avoids excessive clamping force, thus preventing deformation of the part. The specific details are as follows: 1. By setting up a material gripping mechanism, gas can be introduced into the air box using an air pump. Through the air channel and connecting pipe, the gas enters the wave-shaped airbag. Utilizing the wave-like characteristics of the airbag, it can extend. Simultaneously, when the gas enters the airbag clamp at the end of the wave-shaped airbag, it inflates the clamp, allowing it to fit against the inner wall of the automotive part, increasing the contact area and thus improving the gripping support force. At the same time, gas enters the flipping airbags on both sides of the clamp, causing them to inflate and flip. Under the action of these flipping airbags, they can fit against and connect with both sides of the suction cup bracket, sealing both sides of the bracket. Simultaneously, the annular airbag, after being injected with gas and inflating, seals the top and bottom of the suction cup bracket, creating a relatively closed space between the suction cup bracket and the inner wall of the automotive part. This, combined with the suction cup, enhances the suction cup's ability to adsorb the automotive part. The suction force, through the internal support of the airbag, provides soft clamping for the car parts, avoiding excessive clamping force that could cause deformation. Before clamping the car parts, the unfolding motor is started to drive the unfolding main gear to rotate. Utilizing the meshing connection between the unfolding main gear and the unfolding driven gear, the unfolding driven gear drives the unfolding bidirectional threaded rod to rotate. This causes the unfolding threaded sleeves on both sides to move relative to each other, while simultaneously driving the unfolding rotating rod to rotate. This allows the suction cup bracket to unfold relative to each other, thus accommodating car parts of different diameters. When the cleaning brush contacts the inner wall of the car parts, it cleans the inner wall of the car parts by rotating. A certain suction force is generated by the suction pump to absorb debris inside the car parts, preventing debris from adhering to the surface of the suction cup and affecting its suction force. At the same time, the airflow blown out by the suction cup cools the inside of the car parts, making it easier to remove the car parts from the mold. 2. By setting up a robotic arm mechanism, not only can the entire mounting chassis and mounting support be rotated using an electric turntable, but the controller can also control the start and stop of related motors and air pumps. The first bidirectional motor drives the first rotating arm to rotate, and the second bidirectional motor drives the second rotating arm to rotate. The first rotating motor drives the rotating connecting shaft and the fixed column to rotate. Through multi-angle adjustment, it is easy to remove the automotive parts from the mold. At the same time, the second rotating motor is started to drive the rotating main gear to rotate. Utilizing the meshing connection between the rotating main gear and the rotating driven gear, the rotating driven gear drives the fixed top plate to rotate, realizing the rotation of the entire material picking and clamping mechanism. With the cleaning brush on the outside of the suction cup bracket, the inner wall of the automotive parts can be cleaned, improving the stability of picking up the automotive parts.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 , Figure 10 This invention provides a technical solution: a material handling fixture for automotive parts, comprising a material handling clamping mechanism 1 and a fixed top plate 101 mounted on the top of the material handling clamping mechanism 1. A robotic arm mechanism 2 is provided on the top of the material handling clamping mechanism 1, and a gear guard 215 is provided at the end of the robotic arm mechanism 2. The material handling clamping mechanism 1 includes a clamping sleeve 104, with air blowing grooves 106 formed around the inside of the clamping sleeve 104. A connecting pipe 112 is fixedly installed inside the clamping sleeve 104 near the air blowing grooves 106, wherein a wave airbag 113 is fixedly installed at the end of the connecting pipe 112. An airbag clamp 114 is fixedly installed at the end of the airbag 113. A flip-up airbag 115 is fixedly connected to both sides of the airbag clamp 114. Annular airbags 116 are fixedly installed at the top and bottom of the airbag clamp 114. An unfolding groove 105 is formed around the perimeter of the gripping sleeve 104 near the air inlet 106. An air inlet box 107 is formed at the end of the gripping sleeve 104 near the air inlet 106. An air pump 108 is fixedly installed around the top perimeter of the gripping sleeve 104 and is fixedly connected to the air inlet box 107. The air pump 108 blows air into the air inlet box 107. Gas is introduced and, under the action of the air inlet 106 and connecting pipe 112, enters the wave-shaped airbag 113. Utilizing the wave-like characteristics of the wave-shaped airbag 113, it can extend. Simultaneously, when the gas enters the airbag clamp 114 at the end of the wave-shaped airbag 113, it inflates the airbag clamp 114, allowing it to fit against the inner wall of the automotive component, increasing the contact area between the airbag clamp 114 and the inner wall of the automotive component, thereby improving the clamping support force. At the same time, gas enters the flip-over airbags 115 on both sides of the airbag clamp 114, thereby achieving flip-over airbag operation. The airbag 115 inflates and flips, allowing it to fit snugly against both sides of the suction cup bracket 123, sealing both sides of the suction cup bracket 123. Simultaneously, the annular airbag 116 inflates after being injected with gas, sealing the top and bottom of the suction cup bracket 123. This creates a relatively enclosed space between the suction cup bracket 123 and the inner wall of the automotive part, working in conjunction with the suction cup 125 to adsorb the automotive part. This enhances the suction force of the suction cup 125 and provides soft clamping to the automotive part through the airbag's internal support, preventing excessive clamping force that could cause deformation of the part.

[0020] Please see Figures 3-8 A suction pump 109 is fixedly installed at the top center of the clamping sleeve 104. A support base 103 is fixedly installed on the outer side of the clamping sleeve 104 near the air pump 108. Several connecting posts 102 are fixedly installed on the top of the support base 103. The connecting posts 102 are fixedly installed on the bottom of the fixed top plate 101. A suction pipe 110 is fixedly connected to the output end of the suction pump 109. The suction pipe 110 is fixedly installed at the center of the air box 107. Several mounting holes 111 are opened inside the suction pipe 110. An unfolding motor 117 is fixedly installed on the bottom inner side of the clamping sleeve 104. The output end of the machine 117 is fixedly connected to a main unfolding gear 118. A follower unfolding gear 119 is meshed around the main unfolding gear 118. A bidirectional unfolding threaded rod 120 is fixedly mounted on the outer side of the follower unfolding gear 119. The bidirectional unfolding threaded rod 120 is rotatably connected to the clamping sleeve 104 via an unfolding slide groove 105. A threaded unfolding sleeve 121 is symmetrically threaded to the outer side of the bidirectional unfolding threaded rod 120. A rotating unfolding rod 122 is rotatably connected to the outer side of the threaded unfolding sleeve 121. A suction cup bracket 123 is rotatably connected to the end of the rotating unfolding rod 122. The outer center position of the suction cup bracket 123 is fixed. A cleaning brush 124 is installed, and several suction cups 125 are fixedly installed on both sides of the suction cup bracket 123 near the cleaning brush 124. Suction hoses 126 are fixedly connected to the ends of the suction cups 125. The suction hoses 126 are fixedly connected to the suction tubes 110 through the mounting holes 111. Before gripping the automotive parts, the unfolding motor 117 is started to drive the unfolding main gear 118 to rotate. Utilizing the meshing connection between the unfolding main gear 118 and the unfolding driven gear 119, the unfolding driven gear 119 drives the unfolding bidirectional threaded rod 120 to rotate, causing the unfolding threaded sleeves 121 on both sides to move relative to each other, thereby driving the unfolding bidirectional threaded rod 120 to rotate. The rotating rod 122 can be rotated to allow the suction cup bracket 123 to be relatively unfolded, thus accommodating automotive parts of different diameters. When the cleaning brush 124 comes into contact with the inner wall of the automotive part, it can clean the inner wall of the automotive part by rotating. The suction pump 109 generates a certain suction force to absorb the debris inside the automotive part, preventing the debris from adhering to the surface of the suction cup 125 and thus affecting the suction force of the suction cup 125. At the same time, the airflow blown out by the suction cup 125 blows air to cool the inside of the automotive part, making it easier to remove the automotive part from the mold.

[0021] Please see Figures 1-2 , Figures 9-11The robotic arm mechanism 2 includes an electric turntable 201. A mounting base 202 is fixedly connected to the output end of the electric turntable 201. A mounting support 203 is fixedly mounted on the top of the mounting base 202. A controller 204 is fixedly mounted on the outer side of the mounting support 203. A first fixed seat 205 is fixedly mounted at the center of the top of the mounting support 203. A first bidirectional motor 206 is fixedly mounted on the inner side of the top of the first fixed seat 205. A first rotating arm 207 is fixedly connected to each of the two output ends of the first bidirectional motor 206. A second fixed seat 208 is rotatably connected to the end of the first rotating arm 207. A second bidirectional motor 209 is fixedly installed inside. Both output ends of the second bidirectional motor 209 are fixedly connected to the first rotating arm 207. A second rotating arm 210 is fixedly installed on the outer side of the second fixed base 208. A third fixed base 211 is symmetrically installed at the end of the second rotating arm 210. A first rotating motor 212 is fixedly installed on the outer side of one of the third fixed bases 211. A rotating connecting shaft 213 is fixedly connected to the output end of the first rotating motor 212. The rotating connecting shaft 213 is rotatably connected to the third fixed base 211. A fixing post 214 is fixedly installed on the outer side of the rotating connecting shaft 213. A gear protective cover 215 is fixed. A second rotating motor 216 is fixedly installed on one side of the top of the gear protective cover 215, at the end of the fixed column 214. A rotating main gear 217 is fixedly connected to the output end of the second rotating motor 216. A rotating driven gear 218 is meshed with one side of the rotating main gear 217. The rotating driven gear 218 is fixedly connected to the fixed top plate 101. The entire mounting chassis 202 and mounting support 203 are rotated using an electric turntable 201. Simultaneously, the start and stop of related motors and air pumps are controlled by a controller 204. The first bidirectional motor 206 drives the first rotating arm 207 to rotate, and the second bidirectional motor 209... The rotation of the second rotating arm 210 is achieved by using the first rotating motor 212 to drive the rotating connecting shaft 213 and the fixed column 214 to rotate. Through multi-angle adjustment, it is easy to remove the car parts from the mold. At the same time, the second rotating motor 216 is started to drive the rotating main gear 217 to rotate. Utilizing the meshing connection between the rotating main gear 217 and the rotating driven gear 218, the rotating driven gear 218 drives the fixed top plate 101 to rotate, which can realize the rotation of the entire material picking and clamping mechanism 1. With the help of the cleaning brush 124 on the outside of the suction cup bracket 123, the inner wall of the car parts can be cleaned, improving the stability of picking up the car parts.

[0022] Working principle: Before using this type of material handling fixture for automotive parts, it is necessary to check the overall condition of the device to ensure it can operate normally. Figures 1-11As shown, firstly, the entire mounting chassis 202 and mounting support 203 are rotated using an electric turntable 201. Simultaneously, the start and stop of related motors and air pumps are controlled by a controller 204. The first bidirectional motor 206 drives the first rotating arm 207 to rotate, and the second bidirectional motor 209 drives the second rotating arm 210 to rotate. The first rotating motor 212 drives the rotating connecting shaft 213 and the fixed column 214 to rotate. Through multi-angle adjustment, it is easy to remove the automotive parts from the mold. At the same time, the second rotating motor 216 is started to drive the rotating main gear 217 to rotate. Utilizing the meshing connection between the rotating main gear 217 and the rotating driven gear 218, the rotating driven gear 218 drives the fixed top plate 101 to rotate, which enables the rotation of the entire material picking and clamping mechanism 1. With the help of the cleaning brush 124 on the outside of the suction cup bracket 123, the inner wall of the automotive parts can be cleaned, improving the stability of picking up the automotive parts.

[0023] Secondly, gas is introduced into the air box 107 by the air pump 108. Under the action of the air inlet 106 and the connecting pipe 112, the gas enters the wave airbag 113. Utilizing the wave-like characteristics of the wave airbag 113, it can be extended. At the same time, when the gas enters the airbag clamp 114 at the end of the wave airbag 113, it can inflate the airbag clamp 114, allowing it to fit against the inner wall of the automotive parts, increasing the contact area between the airbag clamp 114 and the inner wall of the automotive parts, thereby improving the clamping support force. Simultaneously, gas enters the flip airbags 1 on both sides of the airbag clamp 114. In step 15, the flip airbag 115 expands and flips, allowing it to fit snugly against both sides of the suction cup bracket 123, sealing both sides of the suction cup bracket 123. Simultaneously, the annular airbag 116 expands after being injected with gas, sealing the top and bottom of the suction cup bracket 123. This creates a relatively enclosed space between the suction cup bracket 123 and the inner wall of the automotive part, working in conjunction with the suction cup 125 to adsorb the automotive part, increasing the suction force of the suction cup 125. The airbag provides soft support for the automotive part, preventing excessive clamping force that could cause deformation.

[0024] Finally, before clamping the automotive parts, the unfolding motor 117 is started to drive the unfolding main gear 118 to rotate. Utilizing the meshing connection between the unfolding main gear 118 and the unfolding driven gear 119, the unfolding driven gear 119 drives the unfolding bidirectional threaded rod 120 to rotate. This causes the unfolding threaded sleeves 121 on both sides to move relative to each other, while simultaneously driving the unfolding rotating rod 122 to rotate. This enables the suction cup bracket 123 to unfold relative to each other, thus accommodating automotive parts of different diameters. When the cleaning brush 124 contacts the inner wall of the automotive part, it can clean the inner wall of the automotive part by rotating. The suction pump 109 generates a certain suction force to absorb the debris inside the automotive part, preventing the debris from adhering to the surface of the suction cup 125 and thus affecting the suction force of the suction cup 125. At the same time, the airflow blown out by the suction cup 125 blows air to cool the interior of the automotive part, making it easier to remove the automotive part from the mold.
