Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a part picking device and a material unloading structure. Background Technology

[0002] After a workpiece has been processed in a machining equipment, such as for welding, it needs to be removed from the equipment. This removal requires first lifting the workpiece away from the fixture before unloading it. Currently, the common method for removing workpieces is to use a clamping mechanism to grip or suck up the workpiece from above. This requires a large space on the upper side of the fixture to accommodate the movement of both the clamping mechanism and the workpiece. This necessitates either increasing the height difference between the machining device and the fixture, or adding an unloading station to move the fixture there for easier removal, resulting in a larger equipment size. Those skilled in the art desire a workpiece removal device and unloading structure that can reduce the space required for workpiece removal and unloading, thus reducing the overall size of the equipment. Utility Model Content

[0003] The main purpose of this utility model is to propose a part-picking device and a material-unloading structure, which aims to solve the technical problem of large space required for part picking and unloading in the prior art.

[0004] To achieve the above objectives, this utility model proposes a part-retrieving device, comprising:

[0005] Board picking frame;

[0006] A front-to-back motion device includes a front-to-back drive unit and a front-to-back slide block. The front-to-back drive unit is mounted on the plate-retrieving frame. The front-to-back slide block is connected to the front-to-back drive unit in a transmission manner. The front-to-back drive unit can drive the front-to-back slide block to move in the front-to-back direction.

[0007] A lifting motion device includes a lifting drive unit and a lifting seat. The lifting drive unit is mounted on the front and rear slides. The lifting seat is connected to the lifting drive unit. The lifting drive unit can drive the lifting seat to move in the up and down direction. An extension support is provided on the front side of the lifting seat. The extension support is used to lift the workpiece from below. The extension support can move forward to extend to the lower side of the workpiece and lift the workpiece.

[0008] During material handling, the extended support first moves to a height below the workpiece; then, the front and rear drive units drive the front and rear slides, lifting drive unit, and lifting seat forward, extending the extended support forward to the underside of the workpiece; next, the lifting drive unit drives the lifting seat upward, raising the extended support and lifting the workpiece; then, the front and rear drive units drive the lifting seat backward, with the extended support supporting the workpiece as it moves backward, thus removing the workpiece. In this material handling device, the extended support lifts the workpiece from below before removal. Compared to existing technologies, this technology eliminates the need for a separate clamping mechanism on the upper side of the workpiece, reducing the space required for material handling and thus reducing equipment size.

[0009] Preferably, the plate-retrieving frame is provided with a placement rack, which is used to receive the retrieved workpiece. The extended support can move forward to the front side of the placement rack to lift the workpiece and move backward to place the workpiece downward on the placement rack.

[0010] After the extended support removes the workpiece, it supports the workpiece and moves it to the upper side of the placement rack. Then, the extended support moves downwards, and the workpiece is supported by the placement rack when it touches it. The extended support moves away from the workpiece, and the workpiece is placed on the placement rack. The workpiece can then be further handled and transported. This facilitates the separation of the workpiece and the extended support, making subsequent workpiece processing more flexible.

[0011] Preferably, the placement rack includes at least two placement members, which are spaced apart horizontally. The number of extendable supports is at least two, which are also spaced apart horizontally, and the placement members and extendable supports are staggered horizontally. This ensures that the placement rack and extendable supports do not interfere with each other; the placement rack can support the tray without affecting the movement of the extendable supports.

[0012] Preferably, the protruding support is equipped with a suction cup, which is used to hold the lower side of the workpiece. When the protruding support lifts the workpiece and moves it, the suction cup can hold the workpiece in place to prevent it from shifting during the movement.

[0013] Preferably, the lifting drive unit includes two lifting cylinders, which are respectively located on the left and right sides of the front and rear slide blocks. These lifting cylinders can drive the lifting blocks to move up and down. The two lifting cylinders driving the lifting blocks on both sides improve the stability of the lifting blocks during movement.

[0014] Preferably, two lifting racks are fixedly connected to the front and rear slide blocks, and the two lifting racks are respectively located beside the two lifting cylinders. Two lifting gears are rotatably connected to the lifting base, and the two lifting gears are respectively meshed with the two lifting racks. A synchronous shaft is fixedly connected between the two lifting gears. The two lifting gears rotate synchronously through the synchronous shaft, and in conjunction with the lifting racks, the lifting speed of the two lifting cylinders can be limited to keep them the same, making the movement of the lifting base more stable.

[0015] In another aspect, this utility model also proposes a feeding structure having the above-mentioned picking device. The feeding structure further includes a processing device. The processing device is provided with a processing fixture for positioning the workpiece. The processing device is located on the front side of the picking device. The processing fixture is arranged corresponding to the position of the extended support. The extended support can extend into the processing fixture and lift the workpiece.

[0016] By using the above-mentioned pick-up device, the extended support can extend into the machining fixture and lift the workpiece, which can reduce the space required for picking up and unloading on the upper side of the machining fixture, and help reduce the size of the machining equipment.

[0017] Preferably, the processing equipment further includes a processing device, which is located directly above the processing fixture. The part-removing device employing this technology can reduce the height between the processing device and the processing fixture, thereby reducing the overall height of the processing equipment.

[0018] Preferably, the machining fixture includes a fixture base, a positioning seat is provided on the upper side of the fixture base, the positioning seat is provided with a supporting surface for supporting the workpiece, a height space is provided between the supporting surface and the fixture base to allow the insertion of the protruding support, and the positioning seat and the protruding support are offset to the left and right.

[0019] The workpiece is placed on the support surface of the positioning seat, and the extended support can be inserted into the side of the positioning seat, that is, into the height space between the fixture base and the support surface, so that the extended support can extend to the underside of the workpiece.

[0020] Preferably, the fixture base is provided with a positioning assembly, the positioning assembly including two positioning seats, the two positioning seats are arranged at a distance from each other, the two positioning seats respectively support the front and rear sides of the workpiece, the positioning seats are provided with a clamping slide, the clamping slide can move relative to the positioning seats in the front-back direction, the clamping slide is provided with a clamping mechanism for clamping the workpiece, and an elastic element is connected between the positioning seats and the clamping slide, the elastic element can apply an inward elastic force to the clamping slide;

[0021] The machining fixture also includes two levers that extend in the left-right direction and are arranged at intervals. The levers are located on the lower side of the positioning seat, and the distance between the upper side of the lever and the supporting surface is greater than the height of the protruding support. The clamping slide in the positioning assembly located on the front side is fixedly connected to the lever located on the front side, and the clamping slide in the positioning assembly located on the rear side is fixedly connected to the lever located on the rear side.

[0022] The processing equipment is equipped with a disengaging device, which includes a disengaging front and rear driving device and two actuating members. The two actuating members are arranged at a distance from each other and are located between the two levers. The disengaging front and rear driving device is connected to the two actuating members in a transmission manner. The disengaging front and rear driving device can drive the two actuating members to move closer to each other or further away from each other. When the two actuating members move further away from each other, they can move the two levers to move further away from each other.

[0023] The positioning assembly includes two positioning seats supporting the workpiece on the front and rear sides. Each positioning seat has a clamping mechanism for clamping and positioning the workpiece, providing stable support and positioning. The clamping mechanism, under the action of an elastic element, clamps the workpiece close to it. When it is necessary to remove the workpiece, the disengaging device opens, and the front and rear drive mechanisms drive two actuating elements to disengage the two levers, moving the clamping slides and clamping mechanisms away from the workpiece, allowing it to be lifted and removed. The cooperation of the levers and the disengaging device simplifies the structure of the machining fixture and allows for adaptation to structures requiring movement. Attached Figure Description

[0041] like Figures 1 to 5 As shown, a picking device includes a picking frame 1, a front and rear movement device, and a lifting movement device.

[0042] The front and rear motion device includes a front and rear drive unit 21 and a front and rear slide 22. The front and rear drive unit 21 is mounted on the plate taking frame 1. The front and rear slide 22 is connected to the front and rear drive unit 21 in a transmission manner. The front and rear drive unit 21 can drive the front and rear slide 22 to move in the front and rear direction.

[0043] The lifting motion device includes a lifting drive unit 31 and a lifting seat 32. The lifting drive unit 31 is mounted on the front and rear slide seats 22. The lifting seat 32 is connected to the lifting drive unit 31 in a transmission manner. The lifting drive unit 31 can drive the lifting seat 32 to move in the up and down direction. An extension support 321 is provided on the front side of the lifting seat 32. The extension support 321 is used to lift the workpiece 8 from below. The extension support 321 can move forward to extend to the lower side of the workpiece 8 and lift the workpiece 8.

[0044] When picking up the material, the extended support 321 is first moved to a height below the workpiece 8, as shown in the reference. Figure 1 Then, the front and rear drive unit 21 drives the front and rear slide blocks 22, the lifting drive unit 31, and the lifting seat 32 to move forward, and the extendable support 321 extends forward to the underside of the workpiece 8, as shown in the reference. Figure 2 Then, the lifting drive unit 31 drives the lifting seat 32 to move upward, and the extended support 321 rises upward and lifts the workpiece 8, as shown in the reference. Figure 3 Next, the front and rear drive units 21 drive the lifting seat 32 to move backward, and the extended support 321 supports the workpiece 8 to move backward, as shown in the reference. Figure 4This allows the workpiece 8 to be removed. In this part removal device, the extended support 321 lifts the workpiece 8 from the underside and then removes it. Compared with the prior art, this technology does not require additional space for a clamping mechanism on the upper side of the workpiece 8, which can reduce the space required on the upper side of the workpiece 8 during part removal and unloading, and is beneficial to reducing the size of the equipment.

[0045] In some specific embodiments, the plate taking frame 1 is provided with a placement frame 11, which is used to receive the workpiece 8 after it is taken out. The extended support 321 can move forward to the front side of the placement frame 11 to lift the workpiece 8 and move backward to place the workpiece 8 downward on the placement frame 11.

[0046] After the extended support 321 removes the workpiece 8, it supports the workpiece 8 and moves it to the upper side of the placement rack 11. Then, the extended support 321 moves downward, and the workpiece 8 is supported by the placement rack 11 when it touches it. The extended support 321 moves away from the workpiece 8, and the workpiece 8 is placed on the placement rack 11. (Refer to...) Figure 4 Then, workpiece 8 can undergo other handling and conveying processes, such as being taken away by other handling mechanisms, or being conveyed away by a conveyor mechanism set on the placement rack 11. This facilitates the separation of workpiece 8 and the extended support 321, making subsequent workpiece 8 processing more flexible. When unloading and taking out the next workpiece 8, the previous workpiece 8 needs to be removed first to free up the placement rack 11.

[0047] Furthermore, the placement rack 11 includes at least two placement members 111, which are spaced apart from each other on the left and right. The number of protruding support members 321 is at least two, which are also spaced apart from each other on the left and right. The placement members 111 and the protruding support members 321 are arranged alternately on the left and right. In this way, the placement rack 11 and the protruding support members 321 do not interfere with each other; the placement rack 11 can support the tray without affecting the movement of the protruding support members 321.

[0048] In some specific embodiments, reference is made to Figure 5 The extended support 321 is equipped with a suction cup 4, which is used to hold the lower side of the workpiece 8. When the extended support 321 lifts the workpiece 8 and moves it, the suction cup 4 can hold the workpiece 8 in place to prevent it from shifting during the movement. The suction cup 4 can be connected to a vacuum generator through an air pipe to generate negative pressure.

[0049] In some specific embodiments, reference is made to Figure 5The lifting drive unit 31 includes two lifting cylinders, which are respectively located on the left and right sides of the front and rear slide blocks 22. These cylinders drive the lifting blocks 32 up and down. The two cylinders driving the lifting blocks 32 from both sides improve the stability of the lifting blocks 32 during movement. In other embodiments, the lifting drive unit 31 can also be a lead screw motion module or a rack and pinion motion module. The front and rear drive unit 21 can also be a cylinder, a lead screw motion module, or a rack and pinion motion module.

[0050] Furthermore, two lifting racks 33 are fixedly connected to the front and rear slide blocks 22, and the two lifting racks 33 are respectively located beside the two lifting cylinders. Two lifting gears 34 are rotatably connected to the lifting seat 32, and the two lifting gears 34 are respectively meshed with the two lifting racks 33. A synchronous shaft 35 is fixedly connected between the two lifting gears 34. The two lifting gears 34 rotate synchronously through the synchronous shaft 35. In conjunction with the lifting racks 33, the lifting speed of the two lifting cylinders can be limited to keep them the same, making the movement of the lifting seat 32 more stable.

[0051] On the other hand, refer to Figures 6 to 11 A feeding structure having the above-mentioned part-retrieving device further includes a processing device 5. The processing device 5 is equipped with a processing fixture 6 for positioning the workpiece 8. The processing device 5 is located in front of the part-retrieving device. The processing fixture 6 is positioned corresponding to the position of the extended support 321. The extended support 321 can extend into the processing fixture 6 and lift the workpiece 8. The processing device 5 can be a welding device, etc.

[0052] By using the above-mentioned pick-up device, the extended support 321 can extend into the processing fixture 6 and lift the workpiece 8, which can reduce the pick-up and unloading space required on the upper side of the processing fixture 6, and help reduce the volume of the processing equipment 5.

[0053] In some specific embodiments, the processing equipment 5 further includes a processing device 51, which may be a welding device or the like, and is located directly above the processing fixture 6. The part-removing device employing this technology can reduce the height between the processing device 51 and the processing fixture 6, thereby reducing the overall height of the processing equipment 5.

[0054] In some specific embodiments, the processing fixture 6 includes a fixture base 61, a positioning seat 63 is provided on the upper side of the fixture base 61, the positioning seat 63 is provided with a supporting surface for supporting the workpiece 8, and there is a height space between the supporting surface and the fixture base 61 that allows the protruding support 321 to be inserted. The positioning seat 63 and the protruding support 321 are offset to the left and right.

[0055] Workpiece 8 is placed on the support surface of positioning seat 63. The protruding support 321 can be inserted into the side of positioning seat 63, that is, into the height space between fixture base 61 and the support surface, allowing the protruding support 321 to extend to the underside of workpiece 8. (Refer to...) Figure 11 .

[0056] In some specific embodiments, reference is made to Figures 7 to 9 The fixture base 61 is equipped with a positioning assembly 62, which includes two positioning seats 63 arranged at a distance from each other. The two positioning seats 63 support the front and rear sides of the workpiece 8, respectively. A clamping slide 64 is provided on each positioning seat 63, and the clamping slide 64 can move relative to the positioning seats 63 in a front-to-back direction. A clamping mechanism 65 for clamping the workpiece 8 is provided on the clamping slide 64. An elastic element 66 connects the positioning seats 63 and the clamping slide 64, and the elastic element 66 can apply an inward elastic force to the clamping slide 64. The positioning assembly 62 can be one or more, and multiple positioning assemblies 62 can be arranged at intervals to support the workpiece 8 in multiple positions. The clamping mechanism 65 can adopt a pressing structure with elastic lifting, such as an elastic ball. When approaching the workpiece 8, the workpiece 8 pushes the elastic ball upward, and the elastic ball can press the workpiece 8.

[0057] The machining fixture 6 also includes two levers 67, which extend in the left-right direction and are arranged at intervals. The levers 67 are located on the lower side of the positioning seat 63, and the distance between the upper side of the lever 67 and the supporting surface is greater than the height of the protruding support 321. The clamping slide 64 located on the front side of the positioning assembly 62 is fixedly connected to the lever 67 located on the front side, and the clamping slide 64 located on the rear side of the positioning assembly 62 is fixedly connected to the lever 67 located on the rear side. When the lever 67 is moved outward, the clamping slide 64 compresses the elastic element 66. When the lever 67 is released from clamping the workpiece 8, the elastic element 66 rebounds, causing the clamping slide 64 to move closer to the workpiece 8.

[0058] The processing equipment 5 is equipped with a prying device 7, as shown in the reference. Figure 10 The disengaging device 7 includes a disengaging front-to-back drive mechanism 71 and two actuating elements 72. The two actuating elements 72 are spaced apart and positioned between two levers 67. The disengaging front-to-back drive mechanism 71 is connected to the two actuating elements 72. The disengaging front-to-back drive mechanism 71 can drive the two actuating elements 72 to move closer or further apart. When the two actuating elements 72 move further apart, they can move the two levers 67 further apart. The disengaging front-to-back drive mechanism 71 can be a cylinder, a lead screw motion module, or a gear and rack motion module, etc.

[0059] The two positioning seats 63 in the positioning assembly 62 support the workpiece 8 on the front and rear sides. A clamping mechanism 65 is provided on the positioning seat 63 to clamp and position the workpiece 8, providing stable support and positioning. The clamping mechanism 65, under the action of the elastic element 66, clamps the workpiece 8. When it is necessary to remove the workpiece 8, the disengaging drive 71 of the disengaging device 7 drives two actuating elements 72 to disengage the two levers 67, causing the clamping slides 64 and clamping mechanism 65 on the front and rear sides to move away from the workpiece 8, allowing the workpiece 8 to be lifted and removed. The lever 67 is located on the lower side of the positioning seat 63, and the extended support 321 lifts the workpiece 8 above the lever 67. The lever 67 does not affect the upward movement of the extended support 321 and the workpiece 8. Through the cooperation of the lever 67 and the disengaging device 7, the structure of the machining fixture 6 can be simplified, and the structure of the machining fixture 6 can be adapted to the need for movement. When removing the workpiece, the workpiece only needs to be lifted slightly above the upper side of the clamping mechanism 65 to be removed. The distance between the lower side of the processing device 51 and the upper side of the clamping mechanism 65 should be slightly greater than the thickness of the workpiece.

[0060] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
