Description

Technical Field

[0001] The invention relates to the field of conveyor-related object or material handling devices, and in particular to an automatic feeding device for wiring strip processing. Background Art

[0002] A terminal block (also called a terminal block, terminal disk, terminal box, terminal board, terminal block or terminal block, etc.) is a device used to connect the circuits of the equipment inside the screen and the equipment outside the screen to transmit signals (current and voltage). The use of terminal blocks can make the wiring beautiful and facilitate construction and maintenance, so terminal blocks have been widely used.

[0003] like Figure 1 As shown, the terminal block generally includes a plastic shell 101 and two wire pressing frames 102, a conductive sheet 103, and two nickel-plated steel screws installed in the plastic shell 101. The plastic shell 101 is generally made of materials such as PA66, and the wire pressing frame 102 and the conductive sheet 103 are generally made of metal materials such as brass. The production process of the terminal block mainly includes stamping production (for producing the wire pressing frame 102 and the conductive sheet 103) - injection molding production (for producing the plastic shell 101) - assembly and packaging.

[0004] The main process of assembly and packaging is: collect the above materials - loading - assemble materials - tighten screws - finished inspection - product packaging - shipment / warehousing inspection, among which loading is to move the materials to the conveyor. When loading, the two smaller materials, the wire frame 102 and the conductive sheet 103, are placed on the vibration plate, and the larger material, the plastic shell 101, is placed manually. When loading manually, the speed of human movement is limited. Compared with automated equipment, the frequency of manual placement of the plastic shell 101 is relatively low. For example, on a high-speed industrial production line, dozens or even hundreds of small plastic shells 101 may need to be placed on the conveyor belt every minute, and it is difficult for humans to reach such a speed. Moreover, as the working hours increase, people's fatigue will increase, and the placement speed will further decrease. At the same time, during personnel rotation or rest, the work of placing the plastic shell 101 will be suspended, which will affect the continuity of the entire production process. For example, in a workshop with 24-hour uninterrupted production, if the plastic shell 101 is placed manually, multiple shifts of personnel will need to be arranged, and there may be a lack of smooth work connection during the shift change process. The speed is limited and the production continuity cannot be guaranteed, resulting in low production efficiency.

A semicircular piece 1108 is also fixedly installed on the side of the special-shaped cross bar 1103 away from the bent push rod 1102, and a U-shaped groove 1109 is provided in the bottom of the support groove 2 for the semicircular piece 1108 to slide.

[0062] like Figure 2 , Figure 3 , Figure 4 , Fig.12 , Fig.13 , Fig.14 As shown, the second driving member 10 is equipped with a trigger linkage assembly 14 that can drive the pushing assembly 11 to horizontally push the plastic shell 101 located at the bottom layer on the transfer plate 8 to the picking plate 9 when the picking plate 9 rises. The trigger linkage assembly 14 includes a trigger pin 1401 vertically fixedly installed on the left and right ends of the special-shaped cross bar 1103, and the second flat plate 1001 of the second driving member 10 is equipped with a second inclined wedge 1402 that can rise with the picking plate 9 and can drive the trigger pin 1401 to gradually move backward when gradually rising. The second inclined wedge 1402 is a rod-shaped structure, and the side used to contact the trigger pin 1401 is a horizontal section, an inclined section, and a vertical section from front to back and from top to bottom, which can achieve that the second flat plate 1001 temporarily does not contact the trigger pin 1401 at the initial stage of rising, starts to drive the trigger pin 1401 to move backward after rising to a certain height, and maintains the position of the trigger pin 1401 when it continues to rise.

[0063] like Figure 2 , Figure 3 , Figure 4 , Fig.19 , Fig. 20 As shown, a pressing assembly 16 is fixedly installed on the transfer plate 8, which can press the plastic shell 101 in the barrel 4 downward when the center point of the bottom of the barrel 4 and the center point of the through hole 201 are located on the same vertical line; the pressing assembly 16 includes a vertical pressing rod 1601 that can slide up and down and a bending bracket 1602 fixedly installed on the left and right sides of the transfer plate 8 respectively, and a third plate 1603 is jointly installed on the top of the two bending brackets 1601. The third plate 1603 is provided with a pressing rod through hole for the vertical pressing rod 1601 to pass through. A circular ring block 1604 is fixedly sleeved on the part of the vertical pressing rod 1601 located below the third plate 1603. The vertical pressing rod 1601 is located at the third plate 1603. A third reset spring 1605 is provided on part of the outer sleeve between the three flat plates 1603 and the circular ring block 1604, the top of the third reset spring 1605 is fixedly connected to the bottom of the third flat plate 1603, and the bottom of the third reset spring 1605 is fixedly connected to the top of the circular ring block 1604; rollers 1606 are respectively installed on the left and right sides of the circular ring block 1604, and the central axis direction of the roller 1606 is perpendicular to the conveying direction of the conveyor 3, and the left and right walls of the barrel plug-in frame 5 are provided with V-shaped grooves 1607 with arc-shaped structures at the bottom, which match the number and position of the barrel 4 for the rollers 1606 to slide and can drive the rollers 1606 to rise when the rollers 1606 slide. When the center point of the bottom of the barrel 4 and the center point of the through hole 201 are on the same vertical line, the vertical pressure rod 1601 will press the plastic shell 101 in the barrel 4 downward, making the plastic shell 101 fall more smoothly. As the plastic shell 101 in the barrel 4 continues to decrease, the third return spring 1605 will gradually return from the compressed state to the natural extension state in this process, and the two rollers 1606 will also gradually descend until the plastic shell 101 in the barrel 4 is empty. At this time, the two rollers 1606 are respectively aligned with the V-shaped grooves 1607 on the left and right sides. The arc-shaped bottom is in contact with each other. After the valve is closed, when the barrel plug-in frame 5 slides in the sliding frame 6, the roller 1606 will slide upward along the side wall of the V-shaped groove 1607 to drive the vertical pressure rod 1601 to move upward until the roller 1606 moves to the top of the side wall of the barrel plug-in frame 5. The roller 1606 slides along the top of the side wall of the barrel plug-in frame 5 until it reaches the next V-shaped groove 1607. At this time, the bottom of the vertical pressure rod 1601 has abutted against the top of the uppermost plastic shell 101 in the next barrel 4, and the above process is repeated.

[0064] A main controller is installed on the front frame or the rear frame of the device, an infrared sensor is installed on the rear side of the top of the pick-up support plate 9, and the main controller is connected to the first motor 303, the second motor 702, the second telescopic member 1003, the first telescopic member 1301 and the infrared sensor. The first telescopic member 1301 and the second telescopic member 1003 are cylinders or hydraulic cylinders.

[0065] The working principle of the present invention is as follows: a plurality of plastic shells 101 are stacked from top to bottom in five barrels 4. At this time, the left valve and the right valve are both in a closed state, the front and rear ends of the horizontal rotating shaft 1207 are both located at the bottom of the strip hole 1202, the first return spring 1206 is in a naturally extended state, the special-shaped gear 1209 and the non-standard rack 12010 are in a meshing state, and the door panels 1208 are all in a horizontal state.

[0066] Insert five filled barrels 4 into the barrel insertion frame 5 in sequence, and turn on the first motor 303, the first motor 303 drives the active roller 302 to rotate, the active roller 302 drives the driven roller 304 to rotate through two narrow belts 305, and the conveyor 3 starts to run.

[0067] The second motor 702 is started, and the second motor 702 drives the gear 703 to rotate. The gear 703 rotates and moves along the rack 704, and drives the slide groove 501 of the barrel plug-in frame 5 to slide on the slide rail 601 of the sliding frame 6 through the first flat plate 701, until the barrel plug-in frame 5 is located at the frontmost side of the sliding frame 6, and the center point of the bottom of the barrel 4 located at the rearmost side of the barrel plug-in frame 5 is located on the same straight line as the center point of the through hole 201, and the telescopic end of the first telescopic part 1301 of the left control 13A and the right control 13B begins to extend, driving the connecting plate 1302 to move toward the direction where the center point of the through hole 201 is located, and the first inclined wedges 1303 at the front and rear ends of the connecting plate 1302 both move toward the direction where the center point of the through hole 201 is located, and the bottom of the inclined surface of the first inclined wedge 1303 contacts the horizontal rotating shaft 1207, and the horizontal rotating shaft 1207 begins to move upward along the inclined surface in the strip hole 1202. When sliding, the toothed edge of the special-shaped gear 1209 meshes with the toothed portion of the non-standard rack 12010, so the special-shaped gear 1209 gradually starts to rotate, driving the horizontal shaft 1207 to rotate in the horizontal sleeve 1205, and the horizontal shaft 1207 drives the door panel 1208 to rotate from a horizontal state to a vertical state. When the steering pin 12091 returns to the top of the toggle block 120101, the vertical edge of the special-shaped gear 1209 meshes with the toothed portion of the non-standard rack 12010. When the toothless parts of the standard rack 12010 are in contact with each other, the door panel 1208 is in a vertical state. At this time, the special-shaped gear 1209 no longer rotates, and the horizontal shaft 1207 continues to slide upward along the inclined surface in the strip hole 1202. The first return spring 1206 is compressed, and the door panel 1208 moves upward with the horizontal shaft 1207 until the horizontal shaft 1207 reaches the inner top of the strip hole 1202. At this time, the left valve and the right valve are both in an open state.

[0068] After losing the support of the valve, the plastic shell 101 in the barrel 4 located at the rear side of the barrel insertion frame 5 falls under the action of gravity, and the plastic shell 101 located at the bottom layer of the barrel 4 passes through the through hole 201 at the center of the bottom surface of the support groove 2 and falls vertically to the top of the transfer plate 8.

[0069] The telescopic end of the second telescopic member 1003 begins to shorten, the second flat plate 1001 gradually rises, and the distance between the second flat plate 1001 and the bottom of the mounting frame shortens. The second flat plate 1001 drives the pickup pallet 9 to gradually rise, and the pickup pallet 9 continues to rise after passing through the pallet through hole 30111 on the mounting frame until it passes through the through hole 801 on the rear side of the transfer plate 8 for the pickup pallet 9 and the plastic shell 101 on the pickup pallet 9 to pass through. When the top of the pickup pallet 9 and the top of the transfer plate 8 are in the same plane, the telescopic end of the second telescopic member 1003 stays at this length. When the second plate 1001 rises, the second inclined wedge 1402 installed on the top of the second plate 1001 also rises accordingly. When the second plate 1001 rises to a certain height, the specific value of which is determined according to production needs in actual production, the inclined surface of the second inclined wedge 1402 begins to contact the trigger pin 1401, and the trigger pin 1401 moves backward along the inclined surface, thereby driving the special-shaped cross bar 1103 to move backward. The special-shaped cross bar 1103 drives the two horizontal slide bars 1104 and the bent push rod 1102 to move backward, and at the same time drives the semicircular piece 1108 to slide in the U-shaped groove 1109, which plays a role in stabilizing the formation. The second reset spring 1107 is in a stretched state, and the bent push rod 1102 drives the push block 1101 to move backward, pushing the lowest plastic shell 101 on the transfer plate 8 horizontally onto the pickup tray 9.

[0070] When the infrared sensor on the rear side of the top of the pickup pallet 9 can sense the plastic shell 101, the plastic shell 101 has completely reached the pickup pallet 9, the telescopic end of the second telescopic member 1003 begins to extend, the second flat plate 1001 gradually descends, and the distance between the second flat plate 1001 and the bottom of the mounting frame increases. The second flat plate 1001 drives the pickup pallet 9 to gradually descend, and the plastic shell 101 gradually descends with the pickup pallet 9. The pickup pallet 9 and the plastic shell 101 first pass through the through hole 801 on the rear side of the transfer plate 8 together, and then the left and right ends of the plastic shell 101 are respectively placed on two narrow belts 305, and the plastic shell 101 is transported backwards by the two narrow belts 305, while the pickup pallet 9 continues to descend, passes through the pallet through hole 30111 on the mounting frame alone, and stays under the mounting frame. The telescopic end of the second telescopic member 1003 stays at this length. When the second plate 1001 descends, the second inclined wedge 1402 also descends, and the second return spring 1107 gradually returns from the stretched state to the natural elongated state, thereby driving the special-shaped cross bar 1103 to move forward through the two horizontal slide bars 1104. The special-shaped cross bar 1103 drives the push block 1101 to move forward through the bent push rod 1102, leaving the transfer plate 8. After losing the shielding of the push block 1101, the plastic shell 101 in the barrel 4 at the rear side of the barrel plug-in frame 5 continues to fall onto the transfer plate 8. Then repeat the above-mentioned process of taking and unloading until all the plastic shells 101 in the barrel 4 are taken out.

[0071] After all the plastic shells 101 in the barrel 4 are taken out, the telescopic end of the first telescopic member 1301 begins to shorten, driving the connecting plate 1302 to move in the direction away from the center point of the through hole 201, and the connecting plate 1302 drives the two inclined wedges 1303 to move in the direction away from the center point of the through hole 201, and the first return spring 1206 gradually returns to the natural extension state from the compressed state, driving the horizontal rotating shaft 1207 to slide downward in the strip hole 1202, and when the steering pin 12091 contacts the toggle block 120101, the obstruction of the toggle block 120101 causes the special-shaped gear 1209 to rotate, and the toothed edge of the special-shaped gear 1209 meshes with the toothed part of the non-standard rack 12010, and the special-shaped gear 1209 gradually begins to rotate, driving the door panel 1208 to rotate from the vertical state to the horizontal state through the horizontal rotating shaft 1207. At this time, the left valve and the right valve are both in the closed state.

[0072] The second motor 702 is started, so that the first plate 701 drives the slide groove 501 of the barrel plug-in frame 5 to slide backward on the slide rail 601 of the sliding frame 6, so that the center point of the bottom of the second barrel 4 from the back to the front in the barrel plug-in frame 5 and the center point of the piece hole 201 are located on the same straight line, and the above process of opening the valve, taking out the pieces, and unloading the pieces is repeated until the barrel 4 is emptied, and then the above process of closing the valve and moving the barrel plug-in frame 5 is repeated until the second barrel 4 from the back to the front in the barrel plug-in frame 5 is emptied. The center point of the bottom of the fifth barrel 4 is on the same straight line as the center point of the through hole 201. At this time, all the empty barrels 4 are pulled out, and the filled barrels 4 are quickly inserted into the barrel insertion frame 5. After the fifth barrel 4 from the back to the front in the barrel insertion frame 5 is emptied, the first flat plate 701 is driven by the second motor 702 to drive the slide groove 501 of the barrel insertion frame 5 to slide forward on the slide rail 601 of the sliding frame 6, and the four newly filled barrels 4 can be used in turn.

[0073] Repeat the above process until all conveying work is completed, and then turn off the conveyor 3.

[0074] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
