Description

Technical Field

[0001] This invention relates to the field of sandblasting cleaning technology, and in particular to an automatic feeding device. Background Technology

[0002] Workpieces often have coatings on their surfaces after auxiliary product processing. To improve the quality of subsequent processes, sandblasting is typically used to clean the workpiece surface. Currently, common sandblasting equipment is usually used in conjunction with a conveyor line. Several workpieces enter the sandblasting area along the conveyor line to complete the cleaning process. After cleaning, the workpieces are exited from the sandblasting area by the conveyor line, and then removed from the conveyor line by a robotic arm and placed in a tray.

[0003] In pursuit of increased production capacity, workpieces are often transported in a continuous, close-knit line on conveyor lines. This arrangement forces robotic arms to employ a lateral gripping strategy, applying clamping force to the workpieces from both sides of the conveyor line's width. However, because baffles are typically installed on both sides of the conveyor line to limit workpiece movement, the reach of the robotic arm's grippers is severely restricted. This prevents the grippers from enclosing the lower and middle parts of the workpieces, limiting their action to the top area and resulting in poor gripping stability. Consequently, workpieces are prone to detaching during transport. Furthermore, to improve the unloading cycle time, robotic arms are usually programmed to grip a single row (preset number) of workpieces at a time. This further increases the gripper failure rate, and due to spacing errors between workpieces, the robotic arm may fail to reliably grip the preset number of workpieces.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic unloading device that can reliably and efficiently unload workpieces.

[0006] The objective of this invention is achieved through the following technical solution: an automatic feeding device, comprising: The tray dispensing device stores a number of trays and can dispense the trays one by one to the first position; The material collection device is used to receive cleaned workpieces and is suitable for dividing and collecting continuously flowing workpieces into several groups of workpiece units according to a preset number. A conveying device is used to move workpiece units one by one to the tray at the first position; The receiving device is used to receive a full tray of workpieces and transport it to a second position.

[0007] Furthermore, the material collection device includes a first workpiece conveyor line, an interception mechanism, and a second workpiece conveyor line. Both the first and second workpiece conveyor lines are arranged along the X-axis direction. The input end of the first workpiece conveyor line is connected to the conveyor line of the cleaning equipment, and the input end of the second workpiece conveyor line is connected to the output end of the first workpiece conveyor line. The interception mechanism is located at the output end of the first workpiece conveyor line and is adapted to intercept or allow the workpiece to flow out of the first workpiece conveyor line, so that the second workpiece conveyor line receives a workpiece unit. The conveying device includes a side-pushing mechanism, a transfer platform, and a conveying mechanism. The transfer platform is located on one side of the second workpiece conveying line in the Y-axis direction. The side-pushing mechanism is adapted to push the workpiece unit to the transfer platform along the Y-axis direction. The conveying mechanism is adapted to grab the workpiece unit and convey it to the tray at the first position.

[0008] Furthermore, the interception mechanism includes: First support; The first clamping drive is disposed on the first bracket and has two output ends that can move toward or away from each other along the Y-axis direction; There are two first clamping members, which are respectively connected to different output terminals of the first clamping drive member; The two first clamping members are respectively disposed on both sides of the first workpiece conveyor line in the Y-axis direction. When the workpiece flows to the output end of the first workpiece conveyor line, the two first clamping members can cooperate to clamp the workpiece on both sides in the Y-axis direction to block the workpiece.

[0009] Furthermore, the first workpiece conveyor line is provided with baffles on both sides in the Y-axis direction. The baffles on both sides can be adjusted to face each other or back to back along the Y-axis direction, and the workpiece is limited between the baffles on both sides.

[0010] Furthermore, the side-pushing mechanism includes: The second support is located at the output end of the second workpiece conveyor line; A side-push module is mounted on the second bracket; The lifting drive component is connected to the side push module via a transmission. The second clamping drive is connected to the lifting drive and has two output ends that can move towards or away from each other along the Y-axis. There are two side pushers, each connected to a different output end of the second clamping drive; The lifting drive is adapted to drive the two side pushers to descend to the second workpiece conveyor line to receive the workpiece unit flowing out from the first workpiece conveyor line. The second clamping drive is adapted to drive the two side pushers to clamp the workpiece unit. The side push module is adapted to drive the two side pushers to move along the Y-axis direction to move the workpiece unit to the transfer table.

[0011] Furthermore, the second workpiece conveyor line is unobstructed on both sides in the Y-axis direction, and the bearing surface of the second workpiece conveyor line is flush with the platform surface of the transfer table.

[0012] Furthermore, the second support is provided with a first alignment component, and the transfer platform is provided with a second alignment component. A clamping area is formed between the two side pushers. When the side pusher is at the second workpiece conveyor line, the first alignment component is adapted to extend into the clamping area to push the workpiece unit so that the workpieces of the workpiece unit are close together. When the side pusher is at the transfer platform, the second alignment component is adapted to extend into the clamping area to push the workpiece unit so that the workpieces of the workpiece unit are close together.

[0013] Furthermore, the conveying mechanism includes: Transport module; The third clamping drive is connected to the conveying module in a transmission manner, and the third clamping drive has two output ends that can move towards or away from each other along the Y-axis direction; There are two second clamping components, which are respectively connected to different output ends of the third clamping drive component; The transport module is adapted to drive the second clamping member to move to the transfer table to clamp the workpiece unit, and move it to the first position to place the workpiece unit into the tray.

[0014] Furthermore, the issuing device includes: A material frame, which houses several stacked material trays; The lowering mechanism consists of two sets, which are located on both sides of the material frame in the Y-axis direction. The lowering mechanism is used to support the flange of the bottom material tray. A transfer platform, located below the material frame, includes a platform body and a transfer module that is pulsatorically connected to the platform body. The transfer module can drive the platform body to move directly below the material frame or to the first position. A fixing mechanism is located at the first position; When the platform moves to directly below the material frame, the lowering mechanism is adapted to place the bottommost material tray onto the platform, and the platform is adapted to move the material tray to the first position so that the fixing mechanism clamps the material tray.

[0015] Furthermore, the closing device includes: The material tray unloading line is arranged along the X-axis and located below the transfer platform. The input end of the material tray unloading line is located directly below the first position. The first lifting platform is located at the input end of the material tray unloading line. It can rise to receive the material tray released by the fixing mechanism and place it down on the material tray unloading line. The second lifting platform is located at the output end of the material tray unloading line. It can lift the material tray flowing to the output end of the material tray unloading line and raise it to the second position.

[0016] Compared with the prior art, the present invention has the following beneficial effects: Using the above-described structure, the material collection device can actively separate and collect continuously flowing workpieces according to a preset quantity before the handling device intervenes, thereby forming independent workpiece units. This reduces gap errors between workpieces caused by the conveyor line and avoids clamping and handling workpiece units at the conveyor line, significantly improving the reliability and success rate of the handling device's gripping process. Simultaneously, in conjunction with the coordinated operation of the tray issuing device, handling device, and tray receiving device, a fully automated closed-loop process is achieved, including automatic empty tray supply, orderly handling of workpiece units, and automatic full tray recycling. This effectively ensures the material feeding cycle time and production capacity requirements while avoiding the risk of workpiece slippage during transport. Attached Figure Description

Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0028] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] Please see Figure 1 and Figure 2 As shown, an automatic unloading device corresponding to a preferred embodiment of the present invention includes: a tray issuing device 100, which stores a plurality of trays 500 and is capable of issuing trays 500 one by one to a first position; a collection device 200, which is used to receive cleaned workpieces 600 and is adapted to divide and collect continuously flowing workpieces 600 according to a preset number to form a plurality of workpiece units; a conveying device 300, which is used to convey workpiece units one by one to the trays 500 at the first position; and a tray receiving device 400, which is used to receive the trays 500 after they are fully loaded with workpieces 600 and convey them to a second position.

[0031] The present invention employs the above-described structure, enabling the collecting device 200 to actively separate and collect the continuously flowing workpieces 600 according to a preset quantity before the handling device 300 intervenes, thereby forming independent workpiece units. This reduces gap errors between workpieces caused by the conveyor line and avoids clamping and handling workpiece units at the conveyor line, significantly improving the reliability and success rate of the handling device 300's gripping process. Simultaneously, in conjunction with the coordinated operation of the issuing device 100, the handling device 300, and the receiving device 400, a fully automated closed-loop process is achieved, including automatic empty tray supply, orderly handling of workpiece units, and automatic recycling of full trays. This effectively ensures the material feeding cycle and production capacity requirements while avoiding the risk of workpieces 600 falling off during transfer.

[0032] Furthermore, referring to Figures 2 to 4As shown, the palletizing device 100 includes a pallet frame 110, a lowering mechanism 120, a transfer platform 130, and a fixing mechanism 140. The top and bottom of the pallet frame 110 are open structures, allowing empty pallets 500 to be stacked into the pallet frame 110 from the top. The pallet 500 has a frame structure with a flange 510 around its top perimeter. Two sets of lowering mechanisms 120 are located on either side of the pallet frame 110 along the Y-axis. The lowering mechanisms 120 support the flange 510 of the bottom pallet 500 to support the entire stack of pallets 500. The lowering mechanism 120 includes a support member 121, a first lowering drive member 122, and a second lowering drive member 123. The first lowering drive 122 is a linear cylinder arranged along the Z-axis direction. The second lowering drive 123 is connected to the first lowering drive 122 in a transmission manner. The second lowering drive 123 is a linear cylinder arranged along the Y-axis direction and is connected to the support member 121 in a transmission manner. The support member 121 can move along the Z-axis direction and the Y-axis direction under the drive of the first lowering drive 122 and the second lowering drive 123.

[0033] The transfer platform 130 is located below the material frame 110 and is arranged along the X-axis. The transfer platform 130 includes a platform body 131 and a transfer module 132 that is pulsatorically connected to the platform body 131. The transfer module 132 is a linear module arranged along the X-axis and is capable of driving the platform body 131 to move directly below the material frame 110 or to a first position.

[0034] When the platform 131 is directly below the material frame 110, the lowering mechanism 120 can lower the bottom tray 500 onto the platform 131. Specifically, the first lowering drive 122 can drive the support 121 to descend so that the entire stack of trays 500 is supported on the platform 131. Then, the second lowering drive 123 drives the support 121 to move away from the bottom tray 500 and, with the driving cooperation of the first lowering drive 122, moves it to the flange 510 of the tray 500 above the bottom tray 500, so as to lift and support the other trays 500 except the bottom tray 500, so that the bottom tray 500 is separated and placed on the platform 131.

[0035] The platform 131, driven by the transfer module 132, can move the lowest tray 500 to the first position. The fixing mechanism 140 is located at the first position. After the tray 500 is moved to the first position, the fixing mechanism 140 can clamp the tray 500, thereby completing the tray dispensing. There are two sets of fixing mechanisms 140, arranged opposite each other along the Y-axis. A space for accommodating the tray 500 is formed between the two sets of fixing mechanisms 140. When the tray 500 is placed in this space, the two sets of fixing mechanisms 140 cooperate to clamp the tray 500. Specifically, the fixing mechanism 140 is a cylinder-driven clamping structure, which is a known structure and will not be described in detail here.

[0036] Furthermore, referring to Figure 1 , Figures 5 to 7 As shown, the material collection device 200 includes a first workpiece conveyor line 210, an interception mechanism 220, and a second workpiece conveyor line 230. Both the first and second workpiece conveyor lines 210 and 230 are belt conveyors arranged along the X-axis. The input end of the first workpiece conveyor line 210 is connected to the conveyor line of the sandblasting equipment to receive the workpieces 600 output from it. The input end of the second workpiece conveyor line 230 is connected to the output end of the first workpiece conveyor line 210. The interception mechanism 220 is located at the output end of the first workpiece conveyor line 210 and is adapted to intercept or allow the workpieces 600 to flow out of the first workpiece conveyor line 210, so that after the second workpiece conveyor line 230 receives a preset number of workpieces 600 to form a workpiece unit, it intercepts the workpieces 600 at the first workpiece conveyor line 210.

[0037] The conveying device 300 includes a side-pushing mechanism 310, a transfer table 320, and a conveying mechanism 330. The transfer table 320 is located on one side of the second workpiece conveying line 230 in the Y-axis direction. The side-pushing mechanism 310 is adapted to push the workpiece unit to the transfer table 320 along the Y-axis direction. The conveying mechanism 330 is adapted to grab the workpiece unit and convey it to the material tray 500 at the first position.

[0038] Specifically, the cleaned workpiece 600 sequentially flows through the sandblasting equipment's conveyor line and the first workpiece conveyor line 210 into the second workpiece conveyor line 230. When the second workpiece conveyor line 230 receives a preset number of workpieces 600 (i.e., one workpiece unit), the intercepting mechanism 220 intercepts the workpieces 600 on the first workpiece conveyor line 210 to prevent them from continuing to flow into the second workpiece conveyor line 230. Then, the pushing mechanism 310 pushes the workpieces 600 on the second workpiece conveyor line 230 into the transfer table 320. The conveying speed of the first workpiece conveyor line 210 can be set relatively slow, while the conveying speed of the second workpiece conveyor line 230 can be set relatively fast to prevent congestion caused by prolonged interception of workpieces 600 on the first workpiece conveyor line 210. Furthermore, the first workpiece conveyor line 210 can also be composed of multiple independently operating lines connected together. By adjusting the flow speed between each line, blockage of workpieces 600 on the first workpiece conveyor line 210 can be avoided after interception.

[0039] Furthermore, the first workpiece conveyor line 210 is provided with baffles 240 on both sides of the Y-axis to block the workpieces 600. The baffles 240 are adjustable in the Y-axis direction, and the two baffles 240 can be adjusted towards or away from each other along the Y-axis to accommodate workpieces 600 of different sizes. This will not be described in detail here. The second workpiece conveyor line 230 is unobstructed on both sides of the Y-axis direction, and its bearing surface is flush with the platform of the transfer table 320, so that the side-pushing mechanism 310 can push the workpieces 600 from the second workpiece conveyor line 230 to the transfer table 320.

[0040] The interception mechanism 220 includes a first support 221, a first clamping drive 222, and first clamping members 223. The first clamping drive 222 is disposed on the first support 221 and is a gripper cylinder with two output ends capable of moving in opposite directions or in opposite directions along the Y-axis. There are two first clamping members 223, each connected to a different output end of the first clamping drive 222. The first clamping members 223 are located on both sides of the first workpiece conveyor line 210 in the Y-axis direction. When the workpiece 600 flows to the output end of the first workpiece conveyor line 210, the two first clamping members 223 cooperate to clamp the workpiece 600 on both sides of the Y-axis direction, thereby blocking the workpiece 600.

[0041] Preferably, the interception mechanism 220 further includes an adjustment drive 224 disposed on the first bracket 221, which is an electric cylinder or a pneumatic cylinder arranged along the X-axis direction, and the first clamping drive 222 is pultrusively connected to the adjustment drive 224. The adjustment drive 224 can adjust the position of the first clamping member 223 in the X-axis direction so that the first clamping member 223 is in the optimal clamping position.

[0042] In addition, the material collection device 200 includes an air blowing mechanism 250 located on the conveying path of the first workpiece conveying line 210. The air blowing mechanism 250 can blow air onto the surface of the workpiece 600 to remove sand and dust from the surface of the workpiece 600 and improve the subsequent cleanliness.

[0043] Further, the side-pushing mechanism 310 includes a second support 311, a side-pushing module 312, a lifting drive 313, a second clamping drive 314, and side-pushing members 315. The second support 311 is located at the output end of the second workpiece conveyor line 230, and the side-pushing module 312 is mounted on the second support 311. The side-pushing module 312 is a linear module arranged along the Y-axis. The lifting drive 313 is a linear cylinder arranged along the Z-axis and is drive-connected to the side-pushing module 312. The second clamping drive 314 is a gripper cylinder and is drive-connected to the lifting drive 313. The second clamping drive 314 has two output ends that can move in opposite directions or in opposite directions along the Y-axis. There are two side-pushing members 315, each connected to a different output end of the second clamping drive 314. The side-pushing member 315 is a long strip-shaped structure with its length direction parallel to the X-axis. A space for accommodating workpiece units is formed between the two side-pushing members 315.

[0044] Initially, the two side pushers 315 descend to the second workpiece conveyor line 230 under the drive of the lifting drive 313. The workpieces 600 on the first workpiece conveyor line 210 can move one by one into the space between the two side pushers 315 along the X-axis direction. When a preset number of workpieces 600 enter the clamping area of ​​the side pushers 315, the side pushers 315 move towards each other under the drive of the second clamping drive 314 to clamp the workpieces 600. Then, the side pushers 315 move the workpieces 600 to the transfer table 320 under the drive of the side push module 312. Finally, the side pushers 315 release the workpieces 600 and rise to return to the second workpiece conveyor line 230, and then descend to continue receiving workpieces 600.

[0045] Preferably, the second support 311 is provided with a first alignment component 340, which includes an alignment drive 341 and an alignment component 342. The alignment drive 341 is a linear cylinder arranged along the X-axis direction, and the alignment component 342 is pulsatorically connected to the alignment drive 341. The alignment component 342 corresponds to the open side of the clamping area away from the first workpiece conveying line 210, and is adapted to extend into the clamping area under the drive of the alignment drive 341 to push the workpiece unit so that the workpieces 600 of the workpiece unit are close together.

[0046] Preferably, the transfer table 320 is provided with a second alignment component 350, the structure of which is similar to that of the first alignment component 340, and it is also arranged along the X-axis direction. When the side pusher 315 pushes the workpiece unit to the transfer table 320, the second alignment component 350 corresponds to the open side of the clamping area near the first workpiece conveyor line 210, so as to push the workpiece unit along the X-axis direction, so that each workpiece 600 is close together, which facilitates the subsequent handling by the handling mechanism 330.

[0047] Furthermore, the transfer platform 320 and the fixed mechanism 140 are aligned on the same straight line parallel to the Y-axis to simplify the transport path of the transport mechanism 330. (Refer to...) Figure 8 As shown, the conveying mechanism 330 includes a conveying module 331, a third clamping drive 332, and second clamping members 333. The conveying module 331 consists of two linear modules, one arranged along the Y-axis and the other along the Z-axis. The third clamping drive 332 is connected to the conveying module 331 to move along the Y-axis and Z-axis. The third clamping drive 332 is a gripper cylinder with two output ends capable of moving in opposite directions or in opposite directions along the Y-axis. There are two second clamping members 333, which are respectively connected to different output ends of the third clamping drive 332. The two second clamping members 333 can cooperate to clamp a workpiece unit under the drive of the third clamping drive 332 and move it to the material tray 500 at the first position under the drive of the conveying module 331.

[0048] Furthermore, referring to Figure 2 and Figure 9 As shown, the receiving device 400 includes a tray unloading line 410, a first lifting platform 420, and a second lifting platform 430. The tray unloading line 410 is a roller conveyor arranged along the X-axis direction, located below the transfer platform 130, with its input end positioned directly below the first position. The first lifting platform 420 is located at the input end of the tray unloading line 410 and can rise to receive the tray 500 released by the fixing mechanism 140, and lower it onto the tray unloading line 410. The second lifting platform 430 is located at the output end of the tray unloading line 410 and can lift the tray 500 flowing to the output end of the tray unloading line 410, raising it to the second position for removal by operators or a robotic arm. Both the first lifting platform 420 and the second lifting platform 430 are conventional lifting structures, which will not be described in detail here.

[0049] The working process of the automatic feeding device of the present invention is as follows: the workpiece 600 flowing out of the sandblasting equipment conveyor line flows into the first workpiece conveyor line 210. The workpiece 600 on the first workpiece conveyor line 210 passes through the air blowing mechanism 250 and the intercepting mechanism 220 in sequence before flowing into the second workpiece conveyor line 230. When the second workpiece conveyor line 230 receives a preset number of workpieces 600 to form a workpiece unit, the intercepting mechanism 220 intercepts the workpieces 600 on the first workpiece conveyor line 210. The first straightening component 340 extends into the clamping area to push the workpiece unit so that the workpieces 600 of the workpiece unit are close to each other. The side pusher 315 clamps the workpiece 600 on the second workpiece conveyor line 230 and pushes it to the transfer table 320. Release the workpiece unit, the second aligning component 34 on the transfer table 320 pushes the workpiece unit so that the workpieces 600 in the workpiece unit are close to each other, and then the pusher 315 returns to the second workpiece conveyor line 230; the conveying mechanism 330 transports the workpieces 600 on the transfer table 320 to the tray 500 at the first position; repeat the above actions until the tray 500 is full, the first lifting platform 420 lowers the full tray 500 to the tray unloading line 410, the tray unloading line 410 moves the tray 500 to the output end, the second lifting platform 430 lifts the tray 500 to the second position for the operator or robot to remove, at the same time, the tray dispensing device 100 continues to dispense empty trays 500 to the first position.

[0050] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
