Description

Technical Field

[0001] The present invention relates to the technical field of manipulators, and in particular to a feeding manipulator of a secondary manipulator. Background Art

[0002] Some existing metal parts require a set of dies for multiple continuous stampings, and there are many stamping processes. Therefore, a feeding robot is needed to grab and feed the materials quickly and step by step. However, the existing feeding robot is a single robot with slow grabbing and feeding speeds, which cannot meet the requirements of high-speed stamping of existing stamping dies, thereby reducing the production efficiency of stamping dies. Summary of the invention

[0003] The purpose of the present invention is to provide a synchronous, high-speed, linked, and highly efficient feeding robot for a secondary robot.

[0004] The object of the present invention is achieved in that:

[0005] A feeding robot of a two-dimensional robot comprises a base body, a jaw opening drive device, a jaw opening drive plate and a plurality of jaws, wherein the plurality of jaws are arranged on the base body along the left and right directions of the base body, the jaw opening drive plate is slidably arranged on the base body along the front and rear directions of the base body and is located at the top of the jaws, the jaws comprise a left clamp arm and a right clamp arm, the left clamp arm and the right clamp arm are slidably opened and closed along the left and right directions of the base body, a closing spring is arranged between the left clamp arm and the right clamp arm, a plurality of jaw opening drive blocks are arranged side by side on the jaw opening drive plate, the jaw opening drive block is located between the left clamp arm and the right clamp arm, two driving inclined surfaces are arranged at the front end of the jaw opening drive block, the left clamp arm and the right clamp arm are provided with a first driven inclined surface at the front end of the jaw opening drive block corresponding to the left clamp arm, and the jaw opening drive device is arranged on the base body and drives the jaw opening drive plate to slide. When the left and right clamping arms of the clamping jaws are opened to the maximum, the left and right clamping arms of two adjacent clamping jaws will abut against each other, thereby preventing the left and right clamping arms from further opening and preventing the clamping jaw opening driving block from further moving forward.

[0006] The present invention can also be further improved as follows.

[0007] A synchronous linkage component is provided between the left clamp arm and the right clamp arm, and the synchronous linkage component includes a synchronous push plate, a first synchronous linkage plate and a second synchronous linkage plate, the synchronous push plate is provided on the clamp jaw opening drive block, the first synchronous linkage plate and the second synchronous linkage plate are symmetrically provided on the left and right sides of the synchronous push plate, respectively, the outer end of the first synchronous linkage plate is rotatably connected to the left clamp arm, the outer end of the second synchronous linkage plate is rotatably connected to the right clamp arm, the inner end of the first synchronous linkage plate and the inner end of the second synchronous linkage plate are rotatably connected to the synchronous push plate, when the clamp jaw opens the drive block When sliding forward, the jaw opening drive block drives the synchronous push plate, the inner end of the first synchronous linkage plate and the inner end of the second synchronous linkage plate to move forward together, and the outer ends of the first and second synchronous linkage plates push the left clamp arm and the right clamp arm to the left and right sides respectively. On the contrary, when the jaw opening drive device no longer drives the jaw opening drive block to slide forward, the left clamp arm and the right clamp arm close under the elastic force of the closing spring, and the left clamp arm and the right clamp arm simultaneously push the inner ends of the first synchronous linkage plate and the second synchronous linkage plate inward respectively, and the inner ends of the first and second synchronous linkage plates slide backward synchronously with the jaw opening drive block. Therefore, the synchronous linkage assembly of the present invention enables the left clamp arm and the right clamp arm to close or open synchronously.

[0008] The front and rear ends of the left clamp arm and the right clamp arm are both provided with closing springs, which enable the left clamp arm and the right clamp arm to close quickly to clamp the workpiece firmly and stably. At the same time, the first driven inclined surfaces of the left clamp arm and the right clamp arm drive the clamping jaws to open and move the driving block backwards.

[0009] The inner end of the first synchronous linkage plate and the inner end of the second synchronous linkage plate are coaxially rotatably arranged on the synchronous push plate.

[0010] The front end of the clamp opening drive block is in the shape of a triangular prism. When the front end of the clamp opening drive block slides forward, the two driving inclined surfaces of the triangular prism press the first driven inclined surfaces of the left and right clamp arms, pressing the left and right clamp arms to both sides and separating them, thereby opening the clamp.

[0011] The seat body is provided with a clamping jaw opening and closing guide rail along the left and right directions thereof, and the left clamping arm and the right clamping arm are slidably arranged on the clamping jaw opening and closing guide rail, so that the left clamping arm and the right clamping arm can slide and open and close stably.

[0012] The opposite side walls of the left clamp arm and the right clamp arm are provided with clearance grooves, the clamp jaw opening drive block is located in the clearance groove, and the first driven inclined surface is located on the opposite side walls of the left clamp arm and the right clamp arm.

[0013] The plurality of clamping jaws are located at the front side of the seat body, and the clamping jaw opening driving device is located at the rear side of the seat body.

[0014] The seat body is provided with a first guide rail along the front-rear direction thereof, and the clamping jaw opening driving plate is slidably arranged on the first guide rail, so that the clamping jaw opening driving plate and the clamping jaw opening driving block can slide stably.

[0015] The clamping jaw opening drive device includes a clamping jaw opening servo motor and a slider. The slider is arranged on the base body and slides along the left and right directions of the base body. The clamping jaw opening servo motor is arranged on the base body and is connected to the slider screw. The slider is provided with a driving roller for rotation. The clamping jaw opening driving plate is provided with a second driven inclined surface corresponding to the driving roller. The driving roller abuts against the second driven inclined surface. The clamping jaw opening servo motor drives the slider and the driving roller to slide back and forth. The driving roller presses against the second driven inclined surface. The clamping jaw opening driving plate and the clamping jaw opening driving slider move back and forth, thereby causing the clamping jaw to repeatedly open and close. More specifically, due to the elastic force of the closing spring, the clamping jaw opening driving plate and the clamping jaw opening driving block always maintain a tendency to move backward. When the jaw opening servo motor drives the slider to slide to the left, and the driving roller slides toward the highest point of the second driven inclined surface of the jaw opening driving plate, the driving roller pushes the jaw opening driving plate and the jaw opening driving block to slide forward, and the jaw opening driving plate cannot move backward. When the jaw opening servo motor drives the slider to slide to the right, and the driving roller slides toward the lowest point of the second driven inclined surface of the jaw opening driving plate, the driving roller no longer presses the second driven inclined surface, and the opening driving plate and the jaw opening driving block can move backward.

[0016] The left clamp arm or the right clamp arm is provided with a material grabbing sensor to detect whether there is a workpiece on the clamping jaw.

[0017] The beneficial effects of the present invention are as follows:

[0018] (i) The feeding manipulator of the present invention is provided with multiple clamps side by side, and the multiple clamps are opened or closed synchronously. The multiple clamps can simultaneously convey the workpieces stamped in the previous stamping process of the punch press to the next stamping process for stamping. Therefore, the multiple clamps of the present invention can synchronously convey multiple workpieces, so that the punch press can simultaneously perform continuous and synchronous stamping on multiple workpieces. Therefore, the workpiece transfer efficiency of the present invention is high, the production efficiency is high, and fully automatic continuous high-speed production can be realized. Therefore, the present invention can meet the high requirements of high-speed continuous stamping of existing stamping dies.

[0019] (ii) In addition, a synchronous linkage component is provided between the left and right clamping arms of the clamping jaws, and the synchronous linkage component enables the left and right clamping arms to be synchronously opened or closed at a faster speed, so that the clamping jaws can quickly clamp or release the workpiece.

[0034] As a more specific technical solution of the present invention.

[0035] The horizontal sliding drive device 3 includes a base 1, a left-right moving servo motor 31, two left-right moving seats 32, two front-and-back moving servo motors 33 and a front-and-back moving seat 34. The front-and-back moving seat 34 in this embodiment is the seat body mentioned above. The two left-and-right moving seats 32 are respectively arranged on both sides of the base 1 for horizontal sliding sliding along the left-and-right directions of the horizontal sliding drive device 3. The left-and-right moving servo motor 31 is arranged on the base 1 and located between the two left-and-right moving seats. The motor shaft of the left-and-right moving servo motor is screw-driven with one of the left-and-right moving seats 32. The front-and-back moving seat 34 is horizontally slidably arranged on the base 1 along the front-and-back direction of the horizontal sliding drive device 3 (the front-and-back and left-and-right directions of the horizontal sliding drive device 3 are consistent with the front-and-back and left-and-right directions of the front-and-back moving seat).

More specifically, due to the elastic force of the closing spring 57, the jaw opening driving plate 52 and the jaw opening driving block 56 always maintain a tendency to move backwards. When the jaw opening servo motor 511 drives the slider 512 to slide to the left and the driving roller 514 slides toward the highest point of the second driven inclined surface 513 of the jaw opening driving plate 52, the driving roller 514 begins to push the jaw opening driving plate 52 and the jaw opening driving block 56 to slide forward, and the jaw opening driving plate 52 cannot move backward. When the jaw opening servo motor 511 drives the slider 512 to slide to the right and the driving roller 514 slides toward the lowest point of the second driven inclined surface 513 of the jaw opening driving plate 52, the driving roller 514 no longer presses on the second driven inclined surface 513, and the opening driving plate and the jaw opening driving block 56 can move backward.

[0038] The front end of the clamping jaw opening driving block 56 is in the shape of a triangular prism. When the front end of the clamping jaw opening driving block 56 slides forward, the two driving inclined surfaces 58 of the triangular prism press against the first driven inclined surfaces 59 of the left and right clamping arms 54 and 55, pushing the left and right clamping arms 54 and 55 to both sides, thereby opening the clamping jaws 53.

The synchronous pushing plate 516 is provided on the clamping jaw opening driving block 56, and the first synchronous linkage plate 517 and the second synchronous linkage plate 518 are symmetrically provided on the left and right sides of the synchronous pushing plate 516, respectively. The outer end of the first synchronous linkage plate 517 is rotatably connected to the left clamping arm 54, and the outer end of the second synchronous linkage plate 518 is rotatably connected to the right clamping arm 55. The inner end of the first synchronous linkage plate 517 and the inner end of the second synchronous linkage plate 518 are rotatably connected to the synchronous pushing plate 516. When the jaw opening drive block 56 slides forward, the jaw opening drive block 56 drives the synchronous push plate 516, the inner end of the first synchronous linkage plate 517 and the inner end of the second synchronous linkage plate 518 to move forward together, and the outer ends of the first and second synchronous linkage plates 517 and 518 push the left clamp arm 54 and the right clamp arm 55 to the left and right sides respectively. On the contrary, when the jaw opening drive device 51 no longer drives the jaw opening drive block 56 to slide forward, the left clamp arm 54 and the right clamp arm 55 are closed under the elastic force of the closing spring 57, and the left clamp arm 54 and the right clamp arm 55 simultaneously push the inner ends of the first synchronous linkage plate 517 and the second synchronous linkage plate 518 inward respectively, and the inner ends of the first and second synchronous linkage plates 517 and 518 slide backward synchronously with the jaw opening drive block 56.

[0041] The front and rear ends of the left clamp arm 54 and the right clamp arm 55 are provided with the closing spring 57. The closing spring 57 enables the left clamp arm 54 and the right clamp arm 55 to close quickly to clamp the workpiece 7, and the workpiece 7 is clamped firmly and stably. At the same time, the first driven inclined surface 59 of the left clamp arm 54 and the right clamp arm 55 drives the clamping jaw to open and the driving block 56 to move backward.

[0042] The front-rear movable seat 34 is provided with a clamping jaw opening and closing guide rail 36 along the left and right directions of the horizontal sliding drive device 3, and the left clamping arm 54 and the right clamping arm 55 are slidably arranged on the clamping jaw opening and closing guide rail 36, so that the left clamping arm 54 and the right clamping arm 55 can slide and open and close stably.

[0045] The material distribution mechanism 4 includes a material distribution base, a material distribution cylinder 42 and a material distribution push seat 43. The material distribution push seat 43 is horizontally slidably arranged on the material distribution base 41. The material distribution cylinder 42 is arranged on the material distribution base 41 and is drivingly connected to the material distribution base 41. The material distribution base 41 is provided with a second positioning groove 44 and a positioning plate 45. When the discharge trough 21 of the vibrating feeder 2 conveys the workpiece 7 to the material distribution mechanism 4, the second positioning groove 44 on the material distribution push seat 43 is aligned with the line groove 22 on the discharge trough 21, and the positioning piece on the workpiece 7 smoothly moves from the line groove to the second positioning groove 44. When the material distribution cylinder 42 drives the material distribution push seat 43 to push the workpiece 7 out, the second positioning groove 44 of the material distribution push seat 43 is aligned with the first positioning groove 61 of the workbench, so that the clamping jaw 53 can push the workpiece 7 onto the workbench 6 along the second positioning groove 44, and the positioning piece on the workpiece 7 moves to the first positioning groove 61.

[0047] Working principle of the present invention:

[0048] When the present invention is working, the vibrating feeding plate 2 starts to vibrate and output the workpiece 7 to the feeding mechanism 4, the workpiece 7 moves to the feeding pushing seat 43, the positioning piece on the workpiece 7 smoothly moves from the line groove 22 to the second positioning groove 44 of the feeding pushing seat 43, then the feeding mechanism 4 is started, the feeding cylinder 42 drives the feeding pushing seat 43 to push the workpiece 7 out, the second positioning groove 44 of the feeding pushing seat 43 is aligned with the first positioning groove 61 of the workbench, followed by the left and right movement servo motor 31 drives the entire feeding robot 5 to move left, so that the leftmost clamping jaw 53 of the feeding robot 5 is aligned with the workpiece 7, and then the clamping jaw is opened and the servo motor 511 is started, and the clamping jaw is opened. The jaw opening servo motor 511 drives the slider 512 to slide to the left. When the driving roller 514 slides toward the highest point of the second driven inclined surface 513 of the jaw opening driving plate 52, the driving roller 514 pushes the jaw opening driving plate 52 and the jaw opening driving block 56 to slide forward. The two driving inclined surfaces 58 at the front end of the jaw opening driving block 56 press the first driven inclined surfaces 59 of the left and right clamping arms 54 and 55, thereby pushing the left and right clamping arms 54 and 55 to both sides, thereby opening all the clamping jaws 53, and then the forward and backward moving servo motor 33 drives the entire feeding robot 5 to move forward. The workpiece 7 is located at the first leftmost position of the feeding robot 5. The left and right clamping arms 54 and 55 of the clamping jaws 53 are connected, and then the clamping jaw opening servo motor 511 drives the driving roller 514 to slide toward the lowest point of the second driven inclined surface 513 of the clamping jaw opening driving plate 52. Due to the elastic force of the closing spring 57, the left and right clamping arms 54 and 55 close and clamp the workpiece 7. The left and right clamping arms 54 and 55 push the clamping jaw opening driving plate 52 and the clamping jaw opening driving block 56 to move backward. Then, the left and right moving servo motor 31 drives the entire feeding robot 5 to move to the right. The first clamping jaw 53 conveys the workpiece 7 to the right to the first stamping station on the workbench 6. At the same time, the second clamping jaw 53 will The workpiece 7 punched on the first stamping station is grabbed to the second stamping station on the workbench 6, and the rear clamp 53 will also feed synchronously in the above manner. Finally, the last clamp 53 on the feeding machine will clamp the workpiece 7 on the last stamping station on the workbench 6. After all the clamps 53 complete a feeding, they will reset, and then repeat the above steps to grab the workpiece 7 of the previous stamping station to the next stamping station. Therefore, the multiple clamps of the present invention can continuously and synchronously transport multiple workpieces forward at the same time, so that the punching machine can continuously stamp multiple workpieces at the same time. Therefore, the workpiece transfer efficiency of the present invention is high, the production efficiency is high, and fully automatic continuous high-speed production can be achieved.
