Abstract
Description
Technical Field
[0001] This utility model relates to a workpiece picking and placing device with a nail frame, which can both fix polyurethane-coated sheets on the nail frame and remove parts obtained after the sheets have been thermoformed. Background Technology
[0002] For the preparation of ordinary polyurethane flat sheets, polyurethane foam material is generally sprayed onto a sponge board to form a sheet (substrate), which is then heated and hot-pressed in a hot press, followed by cooling and demolding. For the preparation of polyurethane curved sheets (such as car wheel covers), rivets are inserted around the perimeter of a rivet frame. The rivet frame is heated and hot-pressed together with the substrate. Because the perimeter of the sheet is pulled by the rivets, the edges of the substrate cannot shrink inward during hot pressing, thus forming a curved polyurethane sheet (such as a wheel cover). In existing technology, the steps of fixing the perimeter of the sheet to the rivet frame (inserting rivets around the rivet frame) and removing the formed part from the rivet frame are completed in different equipment, resulting in a complex structure. Furthermore, other auxiliary equipment is required to move the rivet frame. Summary of the Invention
[0003] The purpose of this invention is to provide a workpiece pick-and-place device with a nail frame that can both remove the shaped parts from the nail frame and press the sheet into the nail frame, and can push and pull the nail frame to move.
[0004] A workpiece pick-and-place device with a nail frame, wherein the nail frame 100 is a nail pick-and-place frame 2 located on the worktable 11.
[0005] The pick-and-place frame 2 has upwardly extending pins 101 arranged in a quadrilateral shape; the pins 101 are used to pierce the lower periphery of the sheet to be formed, or the lower periphery of the part obtained after the sheet is formed.
[0006] The workpiece pick-and-place device 1 has a worktable 11 for supporting the pick-and-place nail frame 2, a lower pressure plate 12 that can move up and down relative to the worktable 11 above the worktable 11, and an upper top plate 14 that can move up and down relative to the worktable 11 below the worktable 11. The workpiece pick-and-place device 1 is used to push the formed parts on the pick-and-place nail frame 2 upward, so that the parts are separated from the nails 101, and after the parts are removed and the sheet to be formed is placed on the pick-and-place nail frame 2, the sheet to be formed is pressed down, so that the nails 101 on the pick-and-place nail frame 2 are inserted into the lower periphery of the sheet.
[0007] The nail frame 100 has a recess 672 extending vertically at one end; the worktable 11 includes a pick-and-place track 16 for supporting the nail frame 100; the pick-and-place track 16 includes a left track 161 and a right track 162 extending parallel to each other in the front-back direction; the inner side of the left track 161 (right side) or the inner side of the right track 162 (left side) has a pick-and-place slide rail 17 fixed on the worktable 11, the pick-and-place slide rail 17 has a pick-and-place slider 18, the pick-and-place slider 18 is connected to a pick-and-place linear drive device 200 that drives it to move along the pick-and-place slide rail 17, the pick-and-place slider 18 is connected to a pick-and-place push-pull block 19, the pick-and-place push-pull block 19 has a locking plate 191 extending laterally into the recess 672 on the nail frame 100; the pick-and-place linear drive device 200 drives the pick-and-place slider 18 to move, and drives the nail frame 100 to move back and forth on the pick-and-place track 16 through the pick-and-place push-pull block 19.
[0008] The aforementioned workpiece pick-and-place device with nail frame includes a pick-and-place bracket 10, a worktable 11 mounted on the pick-and-place bracket 10, a lower pressure plate 12 connected to the piston rod of a lower pressure cylinder 13 mounted on the pick-and-place bracket 10 and located above the worktable 11, and an upper top plate 14 connected to the piston rod of an upper top cylinder 15 mounted on the pick-and-place bracket 10 and located below the worktable 11.
[0009] The aforementioned workpiece pick-and-place device with nail frame includes a pick-and-place linear drive device 200 comprising a pick-and-place chain 21, an active pick-and-place sprocket 28, and multiple driven pick-and-place sprockets 29. The pick-and-place chain 21 surrounds the active pick-and-place sprocket 28 and the driven pick-and-place sprockets 29. The active pick-and-place sprocket 28 is connected to the output shaft of a motor that drives its rotation. A pick-and-place slider 18 is fixed on the pick-and-place chain 21.
[0010] The above-mentioned workpiece pick-and-place device with nail frame has a clamping device 300. The clamping device 300 is used to clamp the pick-and-place nail frame 2 onto the pick-and-place track 16 when the upper top plate 14 pushes the formed part on the pick-and-place nail frame 2 upward.
[0011] The aforementioned workpiece pick-and-place device with nail frame includes a clamping device 300 comprising a hook 31 and a pull hook 32. The hook 31 is fixed to the rear end of the worktable 11 and extends forward, with the bottom surface of the hook 31 flush with the upper surface of the nail frame 100. The lower end of the pull hook 32 is connected to a movable block 33 that is movable in the front-back direction, and the movable block 33 is connected to the piston rod of the clamping cylinder 34 that drives it to move up and down.
[0012] When the upper surface of the rear end of the nail frame 100 contacts the hook 31, and at the same time the upper surface of the front end of the nail frame 100 contacts the pull hook 32, the nail frame 100 is pressed firmly onto the pick-and-place track 16.
[0013] The beneficial effects of this utility model are:
[0014] The workpiece pick-and-place device 1 integrates the lower pressure plate 12 and the upper top plate 14. The nail frame does not need to be moved in one station, which realizes both the removal of the formed parts from the nail frame and the pressing of the sheet into the nail frame, saving operation time and simplifying the structure.
[0015] The pick-and-place slide rail 17 is located inside the pick-and-place track 16 (left track 161 or right track 162), and the pick-and-place push-pull block 19 fixed on the pick-and-place slider 18 that slides on the pick-and-place slide rail 17 has a laterally (left-right) extending locking plate 191 that extends into a recess 672 that extends vertically at one end of the nail frame. Therefore, after the pick-and-place push-pull block 19 moves the nail frame forward onto the track in another device, the pick-and-place push-pull block 19 does not need to move and will not obstruct the vertical movement of the track and the nail frame. This simple structure ensures the operation of subsequent steps.
[0016] The clamping device 300 can clamp the pick-and-place frame 2 onto the pick-and-place track 16 when the formed part on the pick-and-place frame 2 is pushed upward by the upper top plate 14. The clamping device 300 adopts a hook 31 with the bottom surface flush with the upper surface of the nail frame, a pull hook 32, a moving block 33, a clamping cylinder 34, etc., which can quickly clamp the front and rear ends of the nail frame onto the worktable 11, or quickly release it. Moreover, when releasing the clamping of the nail frame, the moving block 33 and the pull hook 32 can move away from the front end of the nail frame in the front-back direction, so as not to hinder the front-back movement of the nail frame.

[0028] Connecting block 67, locking block 671, recess 672. Detailed Implementation
[0029] See Figure 1 , 2 The workpiece pick-and-place device 1 shown has a nail frame 100, which is a pick-and-place nail frame 2 located on the worktable 11.
[0030] The pick-and-place frame 2 has upwardly extending pins 101, which are arranged in a quadrilateral shape. The pins 101 are used to pierce the lower periphery of the sheet to be formed, or the lower periphery of the part obtained after the sheet is formed; a connecting block 67 is fixed on the right side of the rear end of the pin frame. The connecting block includes an upwardly extending locking block 671 and a recess 672 that opens to the left (inner side) and extends in the vertical direction.
[0031] The workpiece pick-and-place device 1 is used to push the formed parts on the pick-and-place nail frame 2 upward, so that the parts are separated from the nails 101. After the parts are removed and the sheet to be formed is placed on the pick-and-place nail frame 2, the sheet to be formed is pressed down, so that the nails 101 on the pick-and-place nail frame 2 are inserted into the lower periphery of the sheet. The workpiece pick-and-place device 1 has a worktable 11 for supporting the pick-and-place nail frame 2. Above the worktable 11 is a lower pressure plate 12 that can move up and down relative to the worktable 11, and below the worktable 11 is an upper top plate 14 that can move up and down relative to the worktable 11.
[0032] The workpiece pick-and-place device 1 includes a pick-and-place bracket 10, a worktable 11 mounted on the pick-and-place bracket 10, a lower pressure plate 12 connected to the piston rod of a lower pressure cylinder 13 located above the worktable 11, and an upper top plate 14 connected to the piston rod of an upper top cylinder 15 located below the worktable 11. The cylinder bodies of both the lower pressure cylinder 13 and the upper top cylinder 15 are fixed to the pick-and-place bracket 10.
[0033] The workbench 11 includes a pick-and-place track 16 for supporting the nail frame; the pick-and-place track 16 includes a left track 161 and a right track 162 that extend parallel to each other in the front-back direction; the inner side of the right track 162, i.e. the left side, has a pick-and-place slide rail 17 fixed on the workbench 11, and the pick-and-place slide rail 17 has a pick-and-place slider 18, which is connected to a pick-and-place linear drive device 200 that drives it to move along the pick-and-place slide rail 17.
[0034] The pick-and-place linear drive device 200 includes a pick-and-place chain 21, an active pick-and-place sprocket 28, and multiple driven pick-and-place sprockets 29. The active pick-and-place sprocket 28 is connected to the output shaft of a motor that drives its rotation. A pick-and-place slider 18 is fixed on the pick-and-place chain 21, and a pick-and-place push-pull block 19 is connected to the pick-and-place push-pull block 19. The pick-and-place push-pull block 19 has a retaining plate 191 that extends to the left into a recess 672 on the connecting block 67. The pick-and-place linear drive device 200 drives the pick-and-place slider 18 to move, and drives the nail frame to move back and forth on the pick-and-place track 16 through the pick-and-place push-pull block 19.
[0035] The workpiece pick-and-place device 1 includes a clamping device 300, which is used to clamp the pick-and-place nail frame 2 onto the pick-and-place track 16 when the upper top plate 14 pushes the formed part on the pick-and-place nail frame 2 upward.
[0036] The clamping device 300 includes a hook 31 and a pull hook 32 respectively; the hook 31 is fixed to the rear end of the workbench 11 and extends forward, and the bottom surface of the hook 31 is flush with the upper surface of the nail frame; the lower end of the pull hook 32 is connected to a movable block 33 that is movable in the front-back direction, and the movable block 33 is connected to the piston rod of the clamping cylinder 34 that drives it to move up and down; the cylinder body of the clamping cylinder 34 is fixed on the workbench 11 or the pick-and-place bracket 10.
[0037] When the upper surface of the rear end of the nail frame contacts the hook 31, and the upper surface of the front end of the nail frame contacts the pull hook 32, the nail frame is pressed firmly onto the pick-and-place track 16.
[0038] The working process of the workpiece pick-and-place device with a nail frame is as follows:
[0039] The pick-and-place linear drive device 200 operates, causing the pick-and-place slider 18 and pick-and-place push-pull block 19 to move forward along the pick-and-place chain. The clamping plate 191 pushes the connecting block 67 and the pick-and-place nail frame 2 (on which the sheet to be formed is already mounted) forward, pushing the nail frame 100 on the worktable 11 forward onto a vertically movable track located in another device. The track rises from its starting position, and the recess 672 of the connecting block 67 fixed to the nail frame 100 disengages from the clamping plate 191 of the pick-and-place push-pull block 19. The nail frame 100 then undergoes further processing in the other device, completing the hot-pressing of the sheet, resulting in a nail frame 100 with the formed part. Then, the nail frame 100 with the part descends back to its starting position along the track, and the clamping plate 191 of the pick-and-place push-pull block 19 re-enters the recess 672 of the connecting block 67.
[0040] When the pick-and-place linear drive device 200 is activated, the pick-and-place slider 18 and the pick-and-place push-pull block 19 move backward along with the pick-and-place chain. The clamping plate 191 pulls the connecting block 67 and the nail frame 100 backward, pulling the nail frame 100 with the cooled and formed part backward from the track to the worktable 11 until the nail frame contacts the hook 31.
[0041] The clamping cylinder 34 first drives the hook 32 and the moving block 33 to move upward, so that the hook 32 exceeds the upper surface of the nail pick-and-place frame 2. Then the moving block 33 and the hook 32 move backward to the position of the hook 32 above the upper surface of the nail pick-and-place frame 2. Then the clamping cylinder 34 drives the hook 32 and the moving block 33 to move downward, so that the hook 32 contacts the upper surface of the nail pick-and-place frame 2. The nail pick-and-place frame 2 on the worktable 11 is fixed on the worktable 11 to prevent the nail pick-and-place frame 2 from moving upward.
[0042] The upper cylinder 15 drives the upper plate 14 to rise, pushing the formed part upwards, and the periphery of the part is separated from the material nail 101 on the nail pick and place frame 2.
[0043] Remove the formed part; then the upper cylinder 15 drives the upper plate 14 to descend; place the next sheet to be formed on the pick-and-place frame 2 located on the worktable 11, the lower cylinder 13 drives the lower plate 12 to descend and press down the sheet, and the material nails 101 on the pick-and-place frame 2 pierce the lower periphery of the sheet; the lower cylinder 13 drives the lower plate 12 to rise; the clamping cylinder 34 first drives the hook 32 and the moving block 33 to move upward, so that the hook 32 exceeds the upper surface of the pick-and-place frame 2, then the moving block 33 and the hook 32 move forward, and the hook 32 leaves the upper surface of the pick-and-place frame 2, then the clamping cylinder 34 drives the hook 32 and the moving block 33 to move downward, so that the top of the hook 32 is lower than the lower surface of the pick-and-place frame 2, and the fixation of the pick-and-place frame 2 on the worktable 11 is released, without hindering the forward movement of the pick-and-place frame 2.
