Description

Technical Field

[0001] The utility model relates to the technical field of electronic paper detection, in particular to a material taking arm with a buffer function. Background Art

[0002] Electronic paper, also known as digital paper, is an ultra-thin, ultra-light display screen, which can be understood as a "display as thin, soft, and erasable as paper." Electronic paper has the advantages of paper and can continuously convert and refresh the display content like our common LCD monitors. After production, electronic paper needs to be transported to the inspection station for inspection. In order to improve work efficiency, a robotic arm is usually used to transport electronic paper.

[0003] For example, the Chinese utility model patent with authorization announcement number CN219448439U discloses a pallet circulating feeding mechanism, which includes a conveyor frame, a material conveying line, a temporary storage and circulation mechanism for material trays, and a material transfer mechanism. The material transfer mechanism includes a loading robot and a unloading robot disposed on the conveyor frame. The loading robot places the material on the material loading line onto the topmost pallet at the first stacking station, and the unloading robot grabs the material from the topmost pallet at the second stacking station to the material unloading line. In the pallet circulating feeding mechanism disclosed above, when the loading robot stops suddenly, the suction cup assembly shakes left and right due to inertia. Over time, this may cause the various mechanisms to loosen or even be damaged. Summary of the Invention

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] like Figures 1 to 3 As shown, a material retrieving arm with a buffering function includes a first mounting bracket 1, a second mounting bracket 2, and a Z-axis linear motion module 101. The first mounting bracket 1 and the second mounting bracket 2 are slidably connected via the Z-axis linear motion module 101. The Z-axis linear motion module 101 is fixedly mounted on the first mounting bracket 1. The Z-axis linear motion module 101 is provided with a drive motor for driving the second mounting bracket 2 to move along the Z-axis. The bottom of the second mounting bracket 2 is connected to an electric rotary slide 201, and the bottom of the electric rotary slide 201 is connected to a vacuum suction head assembly 202. The vacuum suction head assembly 202 is detachably connected to the electric rotary slide 201. The electric rotary slide 201 can drive the vacuum suction head assembly 202 to move along the X-axis, the Y-axis, and to swing the vacuum suction head assembly 202 to correct the deviation of the vacuum suction head assembly 202.

[0021] Furthermore, a buffer assembly 208 is provided on the second mounting bracket 2 for cooperating with the vacuum head assembly 202. The buffer assembly 208 is used to prevent the vacuum head assembly 202 from shaking violently under the action of inertia when the material picking arm stops suddenly, thereby causing damage to the electric rotary slide 201. Among them, the vacuum head assembly 202 includes a truss 203, a suction cup arm 206 and a vacuum suction nozzle 207. The truss 203 is an integrally formed structure. The truss 203 includes a bending rod 204 and a straight rod 205. One end of the bending rod 204 is connected to the electric rotary slide 201, and the other end of the bending rod 204 is fixedly connected to the straight rod 205. The vacuum suction nozzle 207 is connected to the suction cup arm 206. The suction cup arms 206 are arranged side by side along both sides of the straight rod 205, and the distance between adjacent suction cup arms 206 is adjustable. The buffer assembly 208 includes a first connecting plate 209, a second connecting plate 210 and a slide cylinder 214. The second connecting plate 210 is arranged below the first connecting plate 209. The cylinder of the slide cylinder 214 is fixed to the first connecting plate 209. The piston rod of the slide cylinder 214 is fixed to the second connecting plate 210. The first connecting plate 209 is connected to the side wall of the second mounting bracket 2. The second connecting plate 210 cooperates with the vacuum head assembly 202 under the drive of the slide cylinder 214 to clamp or separate the vacuum head assembly 202. Specifically, a groove 211 is provided at one end of the second connecting plate 210. A buffer block 212 is provided on the groove 211. The buffer block 212 is made of silicone or rubber. The buffer block 212 is fixedly arranged on the groove 211. A card slot 213 is also provided on the buffer block 212. The card slot 214 on the buffer block 213 cooperates with the bending rod 204 to clamp the vacuum head assembly 202.

[0022] When in use, the material picking arm is installed on the X-axis linear module, and the driving motor on the X-axis linear module drives the material picking arm to move along the X-axis direction. At this time, the slide cylinder 214 drives the second connecting plate 210 to move upward so that the buffer block 212 on the second connecting plate 210 contacts the vacuum suction head assembly 202, and the slot 213 on the buffer block 212 clamps the vacuum suction head assembly 202. When the material picking arm moves above the material, the driving motor on the Z-axis linear motion module 101 drives the material picking arm to move along the Z-axis. When the material picking arm reaches the predetermined position, the slide cylinder 214 drives the second connecting plate 210 to move downward, so that the second connecting plate 210 is separated from the vacuum suction head assembly 202, and then the electric rotary slide 201 corrects the vacuum suction head assembly 202 and sucks the material. After the vacuum suction head assembly 202 sucks the material, the slide cylinder 214 drives the second connecting plate 210 to move upward to clamp the vacuum suction head assembly 202. The material picking arm moves through the Z-axis and X-axis to transport the material to the specified position. Among them, the electric rotary slide 201, the vacuum suction head assembly 202 and the buffer assembly 208 are all a pair, and the pair of electric rotary slides 201 are all arranged at the bottom of the second mounting bracket 2 and the pair of electric rotary slides 201 are mirror-set. By setting a pair of electric rotary slides 201 and the true suction head assembly, the working efficiency of the material picking arm is improved.

[0023] Furthermore, an extension plate 215 is provided on the second mounting bracket 2, and a positioning camera 216 is provided on the extension plate 215. A pair of positioning cameras 216 are arranged side by side on the extension plate 215. The positioning camera 216 is arranged above the vacuum head assembly 202 and cooperates with the vacuum head assembly 202. A manual displacement stage 217 is also provided between the extension plate 215 and the positioning camera 216. The manual displacement stage 217 is also provided with a pair of positioning cameras 216 for adjusting the positioning camera 216 up and down. The manual displacement stage 217 expands the range of movement of the camera. A light source assembly 218 is also provided on the extension plate 215. A pair of light source assemblies 218 are arranged below the positioning camera 216 and cooperate with the positioning camera 216. The light source assembly 218 includes a light source bracket 219 and a light source 220. The light source bracket 219 is connected to the extension plate 215, and the light source 220 is connected to the light source bracket 219.
