Description

Technical Field

[0001] This utility model relates to the field of material handling technology for injection molding robots, specifically to an automatic loading and unloading robot gripping device. Background Technology

[0002] The main function of an injection molding machine is to inject molten plastic into the cavity of a mold through a nozzle to manufacture various plastic products. After the molten plastic is injected into the mold and the mold cools, the injection molded product solidifies. The mold is then manually opened to remove the injection molded product for further processing.

[0003] After the product is formed, the existing injection molding equipment requires the mold to be opened and the molded product to be removed manually. During the manual material removal process, the worker's limbs and arms are likely to come into contact with the equipment. Since the equipment is made of metal, the worker's arms are easily scratched by the equipment. In addition, the efficiency of manual material removal is low, which affects the efficiency of the work. Utility Model Content

[0004] The purpose of this invention is to provide an automatic loading and unloading robot gripping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic loading and unloading robot gripping device includes: a fixed frame, a lower mold fixedly mounted on the top surface of the fixed frame, an upper mold disposed on one side of the lower mold, and an injection molding assembly fixedly mounted on the top surface of the fixed frame; and further includes:

[0007] The suction mechanism is located on one side of the lower mold. The suction mechanism includes a robotic arm fixedly installed on the top surface of the upper mold. A suction head is provided below the robotic arm, and a fixing plate is provided on one side of the suction head. The suction mechanism is used to suction and fix the injection molded parts.

[0008] The clamping mechanism is located on one side of the upper mold. The clamping mechanism includes a connecting strip fixedly installed on the side of the fixed plate. Two limiting grooves are opened on the side of the connecting strip. Clamping rods are slidably installed on the inner walls of the two limiting grooves respectively. The clamping mechanism is used to clamp and fix the injection molded part.

[0009] Preferably, a support frame is fixedly installed at the other end of the robotic arm, and a fixing strip is fixedly installed on the side of the support frame, with a T-shaped groove on the side of the fixing strip.

[0010] Preferably, there are two fixing plates, each with two through slots on its side, and multiple suction heads, each with a nut at one end that is movably connected to the inner wall of one of the through slots.

[0011] Preferably, the two fixing plates are provided with sliding grooves on their sides, the inner walls of the two sliding grooves are slidably connected to the outer wall of the fixing strip, two sliding sleeves are slidably installed on the inner wall of the T-shaped groove, and the two fixing plates are fixedly connected to the inner walls of the two sliding sleeves by bolts.

[0012] Preferably, there are two connecting bars, and two limiting rods are slidably installed on one side of each of the multiple clamping rods, with the multiple limiting rods being fixedly connected to the inner walls of the multiple limiting grooves respectively.

[0013] Preferably, a fixing block is fixedly installed on the side of each of the multiple clamping rods, and a cylinder is fixedly installed on the other side of each of the multiple fixing blocks.

[0014] Preferably, motors are fixedly installed on the sides of the two fixed plates, and rotating shafts are fixedly installed on the output ends of the two motors. The other ends of the two rotating shafts rotate through the sides of the two fixed plates and the sides of the two connecting strips and extend to the other side of the connecting strips.

[0015] Preferably, a rotating plate is fixedly installed at one end of each of the two rotating shafts, and two arc-shaped grooves are respectively opened through the side of each of the two rotating plates, with the inner walls of the multiple arc-shaped grooves slidingly connected to the outer wall of the cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention uses a motor to drive a rotating shaft and a rotating plate to rotate. When the rotating plate rotates, it limits the gripping rods in the limiting groove. When the arc groove on the rotating plate drives the cylinder to move, it drives the two cylinders and two fixed blocks to move closer to each other, and drives the two gripping rods to move closer to each other to clamp the injection-molded product. The product is then removed by a robotic arm, eliminating the need for manual material handling, effectively preventing scratches from manual arms, and improving work efficiency.

[0018] The T-slot limits the sliding sleeve, and the position of the fixing plate can be adjusted by the bolts, sliding sleeve, and fixing plate. This allows for easy adjustment of the suction head position according to the product's location. The suction head then picks up and fixes the product, ensuring that the product is not easily shifted or shaken, thus improving the stability of picking up and placing materials.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] like Figures 1-5 As shown, this application provides an automatic loading and unloading robot gripping device, including: a fixed frame 1, a lower mold 101 fixedly mounted on the top surface of the fixed frame 1, an upper mold 102 provided on one side of the lower mold 101, and an injection molding assembly 103 fixedly mounted on the top surface of the fixed frame 1, and further including:

[0031] The suction mechanism 2 is located on one side of the lower mold 101. The suction mechanism 2 includes a robotic arm 201 fixedly installed on the top surface of the upper mold 102. A suction head 207 is provided below the robotic arm 201. A fixing plate 205 is provided on one side of the suction head 207. The suction mechanism 2 is used to suction and fix the injection molded part.

[0032] Specifically, such as Figures 1-4As shown, a support frame 202 is fixedly installed at the other end of the robotic arm 201, and a fixing strip 203 is fixedly installed on the side of the support frame 202. A T-shaped groove 204 is opened on the side of the fixing strip 203.

[0033] In this embodiment: the robotic arm 201 drives the support frame 202 to move, and the support frame 202 drives the fixing bar 203 to move.

[0034] Specifically, such as Figures 1-4 As shown, there are two fixing plates 205, and two through slots are opened on the side of each fixing plate 205. There are multiple suction heads 207, and one end of each suction head 207 is movably connected to the inner wall of the multiple through slots with a nut.

[0035] In this embodiment, the suction head 207 can be moved in the direction of the suction head 207 by the provided through groove, thereby adjusting the distance between the two suction heads 207 and improving the flexibility of the device.

[0036] Specifically, such as Figures 1-4 As shown, the two fixed plates 205 are respectively provided with sliding grooves 206 on their sides. The inner walls of the two sliding grooves 206 are slidably connected to the outer wall of the fixed strip 203. Two sliding sleeves 208 are slidably installed on the inner wall of the T-shaped groove 204. The sides of the two fixed plates 205 are respectively fixedly connected to the inner walls of the two sliding sleeves 208 by bolts 209.

[0037] In this embodiment: the fixed plate 205 is limited by the sliding groove 206, so that the fixed plate 205 can move on the fixed strip 203. The bolt 209 and the sliding sleeve 208 are used to fix the fixed plate 205.

[0038] The clamping mechanism 3 is located on one side of the upper mold 102. The clamping mechanism 3 includes a connecting strip 301 fixedly installed on the side of the fixing plate 205. Two limiting grooves 302 are opened on the side of the connecting strip 301. Clamping rods 303 are slidably installed on the inner walls of the two limiting grooves 302 respectively. The clamping mechanism 3 is used to clamp and fix the injection molded part.

[0039] Specifically, such as Figures 1-5 As shown, there are two connecting bars 301, and two limiting rods 304 are slidably installed on one side of each of the multiple clamping rods 303. The multiple limiting rods 304 are fixedly connected to the inner wall of the multiple limiting grooves 302 respectively.

[0040] In this embodiment: the clamping rod 303 is limited by the limiting rod 304, and the clamping groove 302 is limited by one end of the clamping rod 303, so that the clamping rod 303 moves more stably.

[0041] Specifically, such as Figures 1-5As shown, a fixing block 305 is fixedly installed on the side of a plurality of clamping rods 303, and a cylinder 306 is fixedly installed on the other side of the plurality of fixing blocks 305.

[0042] In this embodiment: the cylinder 306 moves, which in turn moves the fixing block 305 and the clamping rod 303.

[0043] Specifically, such as Figures 1-5 As shown, motors 307 are fixedly installed on the sides of the two fixed plates 205 respectively, and rotating shafts 308 are fixedly installed on the output ends of the two motors 307 respectively. The other ends of the two rotating shafts 308 rotate through the sides of the two fixed plates 205 and the sides of the two connecting strips 301 respectively and extend to the other side of the connecting strips 301.

[0044] In this embodiment: the motor 307 drives the rotating shaft 308 to rotate, providing power to the device.

[0045] Specifically, such as Figures 1-5 As shown, rotating plates 309 are fixedly installed at one end of the two rotating shafts 308 respectively. Two arc-shaped grooves 310 are respectively opened through the side of the two rotating plates 309. The inner walls of the multiple arc-shaped grooves 310 are slidably connected to the outer wall of the cylinder 306.

[0046] In this embodiment: when the rotating shaft 308 rotates at a certain angle, the rotating shaft 308 drives the rotating plate 309 to rotate. When the rotating plate 309 rotates, the arc groove 310 rotates, thereby driving the two cylinders 306 to move closer to each other.

[0047] Specifically, this solution involves: a T-shaped groove 204 limiting the sliding sleeve 208; and by using bolts 209, the sliding sleeve 208, and the fixing plate 205, the position of the fixing plate 205 can be adjusted, thereby adjusting the position of the suction head 207. This allows for convenient adjustment of the suction head 207's position according to the product's location. Adjusting the robotic arm 201 moves the suction head 207 to the side of the product, where it grips and secures the product, preventing displacement and shaking, thus improving the stability of material handling. Motor 307 drives rotating shaft 308 and rotating plate 309 to rotate. When rotating plate 309 rotates, it limits the clamping rod 303 in limiting groove 302. When the arc groove 310 on rotating plate 309 drives cylinder 306 to move, it drives two cylinders 306 and two fixed blocks 305 to move closer to each other, and drives two clamping rods 303 to move closer to each other to clamp the injection molded product. The product is then taken out by robotic arm 201. There is no need for manual material handling, which effectively prevents scratches from manual arms and improves work efficiency.
