[0035] To make the purpose, technical solution, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The present invention provides a transfer mechanism for workpiece production. A conveying component is arranged at the top of the machine frame. The front end of the top of the conveying component has a buffer component. Two first guide plates and a second guide plate are sequentially arranged behind the buffer component. Both the first guide plate and the second guide plate are connected to an adjusting component. When in use, the machine frame is moved to the position below the tail of the previous conveyor belt.

The position of the guide plate is adjusted by the adjusting component according to the size of different workpieces, and the conveying component conveys the workpiece to the next process, reducing labor costs and preventing workers from being injured during transfer.

[0037] Embodiment 1

[0038] Regarding the above-mentioned problem 1 to be solved: Most of the existing transfer methods are to manually transfer the workpieces conveyed by the previous conveyor belt, which is a waste of human resources, and some workpieces are heavy and easily cause injuries to workers.

[0039] The solution is as follows: A transfer mechanism for workpiece production in this embodiment includes a machine frame 100, a conveying component 200, a buffer component 300, a first guide plate 400, a second guide plate 500, and an adjusting component 600.

[0040] The conveying assembly 200 includes two mounting brackets 210 symmetrically installed on the top of the frame 100 and a conveyor belt 220 connected between the two mounting brackets 210. A rotating shaft 211 is rotatably connected between the two mounting brackets 210. There are two rotating shafts 211 which are symmetrically connected to the front end and the rear end of the mounting bracket 210. The conveyor belt 220 is connected to the outer walls of the two rotating shafts 211. A third motor 230 is installed at the bottom of the mounting bracket 210. A third pulley 231 is installed at the output end of the third motor 230. The other end of the rotating shaft 211 is installed with a second pulley 221. The second pulley 221 and the third pulley 231 are connected by a belt. By starting the third motor 230 to drive the third pulley 231 to rotate, when the third pulley 231 rotates, it drives the second pulley 221 and the rotating shaft 211 to rotate by means of the belt. When the rotating shaft 211 rotates, it drives the conveyor belt 220 to rotate, pushing the workpiece on its top to move from the front of the conveyor belt 220 to the rear.

[0041] The buffer assembly 300 is installed at the front end position on the top of the mounting bracket 210 and is used to receive the workpiece conveyed from the previous conveyor belt to the top of the conveyor belt 220 and buffer it. The buffer assembly 300 includes a second mounting plate 310 installed on the side wall of the mounting bracket 210, a cylinder 320 installed on the top of the second mounting plate 310, and a moving block 330 located on the top of the conveyor belt 220. A connecting shaft 321 is installed at the movable end of the cylinder 320. The other end of the connecting shaft 321 is connected to the moving block 330. The top of the moving block 330 has a first inclined surface 331 inclined towards the front end of the conveyor belt 220. The opposite surfaces of the two moving blocks 330 have a second inclined surface 332. When the workpiece is conveyed from the previous conveyor belt to the top of the conveyor belt 220, the workpiece naturally inclines and leans on the surface of the first inclined surface 331. At this time, the cylinder 320 is started to drive the connecting shaft 321 to contract. The connecting shaft 321 drives the moving block 330 to move towards the cylinder 320. The two moving blocks 330 move away from each other. The workpiece slowly slides down along the second inclined surface 332 to the surface of the conveyor belt 220. At this time, the workpiece lies flat on the surface of the conveyor belt 220 and is conveyed backward along with the conveyor belt 220.

[0042] There are two first guide plates 400, which are symmetrically located at the top of the conveyor belt 220 and behind the buffer assembly 300. There are two second guide plates 500, which are symmetrically located at the top of the conveyor belt 220 and behind the first guide plates 400. There are four adjusting assemblies 600, which are respectively connected to the two first guide plates 400 and the two second guide plates 500 for adjusting the positions of the first guide plates 400 and the second guide plates 500. The adjusting assembly 600 includes a fixed block 610 installed on the side wall of the mounting frame 210, a first adjusting nut 620 arranged on the side wall of the fixed block 610, a first adjusting bolt 630 passing through the fixed block 610 and connected to the first adjusting nut 620, a floating block 640 installed on the top of the first adjusting bolt 630, a second adjusting nut 650 arranged on the top of the floating block 640, and a second adjusting bolt 660 passing through the floating block 640 and connected to the second adjusting nut 650. The other ends of the second adjusting bolts 660 are respectively connected to the two first guide plates 400 and the two second guide plates 500. By rotating the first adjusting nut 620, the first adjusting bolt 630 moves up and down. The first adjusting bolt 630 drives the floating block 640 to move up and down, and the floating block 640 drives the corresponding first guide plates 400 and second guide plates 500 to move up and down. By rotating the second adjusting nut 650, the second adjusting bolt 660 moves left and right, and the second adjusting bolt 660 drives the corresponding first guide plates 400 and second guide plates 500 to move left and right, so as to adjust the positions of the first guide plates 400 and the second guide plates 500 to facilitate the guiding and conveying of workpieces of different sizes.

[0043] Embodiment 2

[0044] Regarding the above-mentioned problem 2 to be solved: In the existing method of using a transfer rack for transfer, the transfer rack generally needs to be located below the tail of the previous conveyor belt, and most of the existing transfer racks have a fixed height, which is not convenient to adjust the height according to different previous conveyor belts.

[0045] The solution is as follows: A workpiece production transfer mechanism in this embodiment further includes a limiting assembly 700.

[0046] The frame 100 includes a lower frame 110 and an upper frame 120 connected to the top of the lower frame 110. At the four corners of the top of the lower frame 110, first support columns 111 are installed. At the top of the first support columns 111, first guide rods 112 are installed. At the four corners of the bottom of the lower frame 110, universal wheels 113 are provided. At the four corners of the top of the upper frame 120, second support columns 121 are installed. At the bottom of the second support columns 121, first guide holes 122 are opened. The first guide rods 112 extend into the interior of the first guide holes 122. Inside the lower frame 110, two mounting plates 130 are symmetrically installed. At the bottom of the mounting plates 130, second guide rods 131 are installed. On the top of one of the mounting plates 130, a first motor 140 is installed. At the bottom of the mounting plate 130, a first threaded rod 150 is rotatably connected. At the top of the first threaded rod 150, a first pulley 151 is installed. Between the two first pulleys 151, a belt is connected. One of the first pulleys 151 is connected to the output end of the first motor 140. On the symmetric side walls of the lower frame 110, two first fixing plates 160 are installed. On the top of one of the first fixing plates 160, a first connecting column 161 is installed. At the top of the first connecting column 161, a second threaded hole 162 is opened. On the top of the other first fixing plate 160, a second connecting column 163 is installed. At the top end of the second connecting column 163, a second guide hole 164 is opened. On the symmetric side walls of the upper frame 120, second fixing plates 170 are installed. On the top of one of the second fixing plates 170, a second motor 171 is installed. At the output end of the second motor 171, a second threaded rod 172 is installed. The second threaded rod 172 rotates and extends into the interior of the second threaded hole 162. At the bottom of the other second fixing plate 170, a second guide rod 173 is installed. The second guide rod 173 extends into the interior of the second guide hole 164. By starting the second motor 171 to drive the second threaded rod 172 to rotate, when the second threaded rod 172 rotates, it uses the screw structure to push the first connecting column 161 and the first fixing plate 160 to move up and down. Since the frame 100 is fixed to the ground and cannot move downward, the upper frame 120 is then pushed upward to adjust the height of the upper frame 120 and the conveying assembly 200, so as to conveniently adjust the height of the conveying assembly 200 to a position below the previous conveyor belt.

[0047] The limit component 700 includes a lifting plate 710 located inside the lower frame 110, a footrest 720 located at the bottom of the lifting plate 710, and a fixing frame 730 installed at the top of the lifting plate 710. Side plates 711 are installed on the symmetrical side walls of the lifting plate 710. A first threaded hole 712 and a first guiding hole 713 are provided at the top of the side plate 711. The first threaded rod 150 rotates through the first threaded hole 712, and the second guiding rod 131 passes through the first guiding hole 713. A lifting block 721 is hinged to the top of the footrest 720. A third threaded hole 722 is provided at the top of the lifting block 721. Sliders 723 are installed on the symmetrical side walls of the lifting block 721. A knob 731 is rotatably connected to the top of the fixing frame 730. A third threaded rod 732 is installed at the bottom of the knob 731. Chute grooves 733 are provided on the symmetrical side walls of the fixing frame 730. The third threaded rod 732 rotates and extends into the third threaded hole 722. The slider 723 is located inside the chute groove 733. By pushing the lower frame 110 to drive the universal wheels 113 to rotate by rubbing against the ground, the lower frame 110 is moved. The lower frame 110 is moved to the tail end of the front conveyor belt. At the same time, the first motor 140 is started to drive one of the first belt pulleys 151 and the first threaded rod 150 to rotate. The first belt pulley 151 drives the other first belt pulley 151 and the first threaded rod 150 to rotate synchronously by using a belt. When the first threaded rod 150 rotates, it uses a screw structure to push the side plate 711 to drive the lifting plate 710 to move downward. The lifting plate 710 drives a plurality of lifting blocks 721 and footrests 720 to move downward until the bottom of the footrest 720 abuts against the ground and pushes the lower frame 110 to move upward, and the universal wheels 113 are separated from the ground, so as to fix the position of the frame 100. At the same time, the knob 731 can be rotated to drive the third threaded rod 732 to rotate, and the screw structure is used to push the lifting block 721 to drive the footrest 720 to move up and down, and the height of each footrest 720 is adjusted separately to adapt to the ground with different inclination angles and keep the conveying component 200 horizontal.
