Description

Technical Field

[0001] This utility model relates to a coating and feeding device for automotive windshield wiper blades. Background Technology

[0002] The steel blades of automotive windshield wipers need to undergo electroplating to improve their corrosion resistance. To ensure that each blade is evenly electroplated and to avoid overlapping, current technology generally uses manual loading. The specific operation is as follows: First, a steel blade support frame is taken. This support frame has slots on both inner sides corresponding to the ends of the steel blades, and a long-handled hook is fixed to one end. Then, multiple curved steel blades are inserted into the support frame. After insertion, the steel blades are manually arranged to maintain a suitable spacing between each pair of blades.

[0003] This feeding method has the following drawbacks: low feeding efficiency; although it requires less physical effort, the long-term repetitive operation will still make the workers tired; although the spacing between the steel sheets is adjusted afterward, it is still difficult to keep the spacing between the steel sheets uniform. If the spacing is too large, it will reduce the number of steel sheets on the steel sheet support frame, which will further reduce the efficiency; if the spacing is too small and the two steel sheets are too close, the vibration when moving the steel sheet support frame may cause the steel sheets to shift, causing the two steel sheets to overlap and requiring readjustment. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a steel sheet coating and feeding device for automotive wipers, which can replace manual labor to realize the automated processing of placing steel sheets into steel sheet support frames. It also has the advantages of high feeding efficiency and uniform distribution of steel sheets placed on steel sheet support frames.

[0005] The technical solution of this utility model is: a coating and feeding device for automotive windshield wiper steel blades, including a frame, a guiding mechanism disposed at one end of the frame, an output mechanism disposed at the other end of the frame, and a feeding mechanism disposed between the guiding mechanism and the output mechanism;

[0006] The guiding mechanism is an inclined plate fixed on the frame. Multiple steel sheets are densely arranged on the inclined plate. Above the lower end of the inclined plate, there is a first pushing mechanism for pushing the steel sheets down along the inclined plate and a second pushing mechanism for pressing the steel sheets down one by one.

[0007] The feeding mechanism includes an arrangement mechanism, a transfer mechanism, and a locking mechanism;

[0008] The arrangement mechanism includes a first frame telescopically connected to the underside of the inclined plate. The top of the first frame is provided with multiple first slots corresponding to the steel sheets at equal intervals. The first frame extends synchronously in coordination with the second pushing mechanism.

[0009] The transfer mechanism includes a main body that moves back and forth between the arrangement mechanism and the locking mechanism. The main body includes a movable seat and a second frame that is lifted and connected to the movable seat. The movable seat is movably connected to the frame. The top of the second frame is connected to two trays that open and close. The top of the two trays is respectively provided with a second slot corresponding to the first slot.

[0010] When the two pallets are closed, a gap is maintained between the two pallets, and the gap is greater than the width of the first frame.

[0011] The locking mechanism includes a first pressure plate and a second pressure plate that are telescopically connected to both sides inside the frame;

[0012] The second frame of the transfer mechanism rises and receives the steel sheets arranged on the first frame, and then transports the steel sheets between the first pressure plate and the second pressure plate. The first pressure plate and the second pressure plate extend simultaneously to bend the steel sheets into a large arc shape. Before the first pressure plate and the second pressure plate bend the steel sheets, the two support plates of the second frame open.

[0013] The first pressure plate has a clearance groove corresponding to the handle of the long-handled hook, and a limit rod is telescopically connected to the frame above the second pressure plate. The upper end of the steel sheet support frame facing the second pressure plate has a waist hole corresponding to the limit rod. The steel sheet support frame is limited above the first pressure plate and the second pressure plate.

[0014] After the first and second pressure plates extend, their inner sides are flush with the lower inner edge of the steel sheet support frame. The second frame rises for the second time to push the bent steel sheet into the two slots of the steel sheet support frame.

[0015] The output mechanism is located at the end of the frame near the insertion mechanism. A flat bracket is telescopically and vertically connected to the output mechanism. The bracket extends between the second frame and the steel plate support frame. Then, the bracket rises to lift the steel plate support frame away from the limit and transport it to the top of the output mechanism.

[0016] Furthermore, both the first and second pushing mechanisms are cylinders. The piston rod of the cylinder extends and retracts to push the steel sheet to move or move downward. The extension or lifting of the telescopic rod, the first pressure plate, the second pressure plate, the second frame, and the bracket are all driven by the cylinder.

[0017] Furthermore, a limiting plate is provided on one side of the inclined plate, and a guide plate is also provided on the lower end of the inclined plate.

[0018] Furthermore, the top of the first frame has a pair of protrusions, and the first slots are respectively disposed on the top of the two protrusions.

[0019] Furthermore, a first guide rail is provided on the frame below the inclined plate, and a first lead screw mechanism driven by a stepper motor is provided at the end of the first guide rail. The first frame is movably connected to the first guide rail and connected to the lead screw of the first lead screw mechanism.

[0020] Furthermore, the frame is also provided with a second guide rail and a second lead screw mechanism driven by a servo motor in the middle, and the movable seat is movably connected to the second guide rail and connected to the lead screw of the second lead screw mechanism.

[0021] Furthermore, an auxiliary support rod is provided on the second frame on the outer side of the two pallets. When the transfer mechanism takes the arranged steel sheets from the arrangement mechanism, the two pallets are in a closed state, and the two ends of each steel sheet rest on the auxiliary support rod.

[0022] Furthermore, a reversible motor is fixed to the top of the second frame, and a slide rail is connected between the two ends of the two auxiliary support rods. The two support plates are slidably connected to the two slide rails by sliders. A rack is fixed to the middle of the two support plates. A gear is set and fixed to the output axis of the reversible motor, and the two racks are respectively meshed on both sides of the gear.

[0023] Furthermore, the edge width of the upper end of the slot in the steel sheet support frame is greater than the edge width of the lower end of the slot to prevent the steel sheet from being directly ejected from the steel sheet support frame during the process of being pushed in.

[0024] Furthermore, the bracket is composed of two plates with hooks at the front ends.

[0025] The beneficial effects of this utility model are:

[0026] 1. It can replace manual labor to automate the process of placing steel sheets into steel sheet support frames. It also has the advantages of high feeding efficiency and uniform and reasonable distribution of steel sheets placed on steel sheet support frames.

[0027] 2. The layout is reasonable and compact. When the transfer mechanism works with the clamping mechanism to clamp and feed the steel sheets, the arrangement mechanism works with the first and second pushing mechanisms to organize the steel sheets, which helps to improve the processing cycle.

[0028] 3. The first pushing mechanism (cylinder) and the second pushing mechanism (cylinder) set above the lower end of the inclined plate work together. The first pushing mechanism first pushes the steel sheet down the inclined plate one by one, and the second pushing mechanism then presses down the steel sheet located at the lower edge of the inclined plate one by one, so that it descends vertically evenly, which can ensure that the steel sheet on the arrangement mechanism is evenly and consistently distributed.

[0029] 4. The first frame of the arranging mechanism and the second frame of the transfer mechanism are respectively equipped with slots for corresponding steel sheets to ensure the stability of the steel sheets during the arranging and transfer process and prevent displacement.

[0030] 5. The upper frame is designed to rise twice, corresponding to the steps of receiving steel sheets from the first frame and pushing the neatly arranged steel sheets into the steel sheet support frame;

[0031] 6. During the process of inserting the steel sheet into the steel sheet support frame, the structural design of the transfer mechanism and the insertion mechanism allows the first and second pressure plates to extend simultaneously and bend the steel sheet into a large arc shape. Before bending, the two support plates of the second frame are opened to prevent the steel sheet from popping out during the bending process. After the first and second pressure plates extend, their inner sides are flush with the lower inner edge of the steel sheet support frame, ensuring that the steel sheet can be smoothly pushed into the steel sheet support frame.

[0032] 7. The long-handled hook on one side of the steel sheet support frame is inserted into the clearance groove of the first pressure plate, and the other side is limited by the limiting rod. It is suspended above the insertion mechanism. With the width difference design of the top and bottom edges of the slot, the steel sheet is not easy to pop out during the insertion process, and it is easy for the output mechanism to lift it out of the limit and then transport it.

[0040] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0041] Combination Figure 1-6 As shown, the automotive wiper blade steel sheet coating and feeding equipment includes a frame 1, a guiding mechanism disposed at one end of the frame 1, an output mechanism 2 disposed at the other end of the frame 1, and a feeding mechanism disposed between the guiding mechanism and the output mechanism 2.

[0042] The guiding mechanism is an inclined plate 3 fixed on the frame 1. Multiple steel sheets 4 are densely arranged on the inclined plate 3. A first pushing mechanism 5 for pushing the steel sheets 4 down along the inclined plate 3 and a second pushing mechanism 6 for pressing the steel sheets 4 down one by one are provided above the lower end of the inclined plate 3. The first pushing mechanism 5 and the second pushing mechanism 6 cooperate to make the steel sheets 4 leave the lower end of the slope at a uniform speed and descend vertically one by one.

[0043] The feeding mechanism includes an arrangement mechanism, a transfer mechanism, and a locking mechanism;

[0044] The arrangement mechanism includes a first frame 7 telescopically connected below the inclined plate 3. The top of the first frame 7 is provided with multiple first slots 8 corresponding to the steel sheets 4 at equal intervals. The first frame 7 extends synchronously with the action of the second pushing mechanism 6, so that each vertically descending steel sheet 4 is placed into the corresponding first slot 8 and arranged at equal intervals.

[0045] The transfer mechanism includes a main body that moves back and forth between the arrangement mechanism and the locking mechanism. The main body includes a movable seat 9 and a second frame 10 that is lifted and connected to the movable seat 9. The movable seat 9 is movably connected to the frame 1. The top of the second frame 10 is connected to two trays 11 that open and close. The tops of the two trays 11 are respectively provided with second slots 12 corresponding to the first slot 8.

[0046] When the two pallets 11 are closed, a gap is maintained between the two pallets 11, and the gap is greater than the width of the first frame 7;

[0047] The locking mechanism includes a first pressure plate 13 and a second pressure plate 14 that are telescopically connected to both sides inside the frame 1.

[0048] The second frame 10 of the transfer mechanism rises and receives the steel sheet 4 arranged on the first frame 7, and then transports the steel sheet 4 between the first pressure plate 13 and the second pressure plate 14. The first pressure plate 13 and the second pressure plate 14 extend simultaneously to bend the steel sheet 4 into a large arc shape. Before the first pressure plate 13 and the second pressure plate 14 bend the steel sheet 4, the two support plates 11 of the second frame 10 are opened to prevent the steel sheet 4 from popping out during the bending process.

[0049] It also includes a steel sheet support frame 15, with two inner sides of the steel sheet support frame 15 having corresponding insertion grooves for the ends of the steel sheet 4. One end of the steel sheet support frame 15 is fixed with a long-handled hook 16. The first pressure plate 13 has a clearance groove 17 corresponding to the handle of the long-handled hook 16. A limiting rod 18 is telescopically connected to the frame 1 above the second pressure plate 14. The upper end of the side of the steel sheet support frame 15 facing the second pressure plate 14 has a waist hole corresponding to the limiting rod 18. The steel sheet support frame 15 is limited above the first pressure plate 13 and the second pressure plate 14.

[0050] After the first pressure plate 13 and the second pressure plate 14 extend out, their inner sides are flush with the lower inner edge of the steel sheet support frame 15. The second frame 10 rises for the second time and pushes the bent steel sheet 4 into the two slots of the steel sheet support frame 15.

[0051] The output mechanism 2 is located at the end of the frame 1 near the insertion mechanism. A flat bracket is connected to the output mechanism 2 for telescopic and lifting. When the steel sheet 4 is inserted into the steel sheet support frame 15 and the second frame 10, the first pressure plate 13 and the second pressure plate 14 are all reset, the bracket extends between the second frame 10 and the steel sheet support frame 15. The limiting rod 18 retracts, the bracket rises, lifts the steel sheet support frame 15 to remove it from the limit, and then transports it above the output mechanism 2.

[0052] The working principle of the above structure is as follows: The arc-shaped steel sheets 4 are neatly arranged on the inclined plate 3 using manual labor or a robotic arm. The steel sheet support frame 15 is placed and positioned above the first pressure plate 13 and the second pressure plate 14, and the equipment is started. Under its own weight and with the cooperation of the first pushing mechanism 5 and the second pushing mechanism 6, the steel sheets 4 descend vertically from the lower end of the inclined plate 3 one by one. At this time, the first frame 7 extends synchronously with the second pushing mechanism 6, so that each vertically descending steel sheet 4 is placed into the corresponding first slot 8 and arranged at equal intervals. When a sufficient number of steel sheets 4 are arranged on the first frame 7, the steel sheets... 4. The output is paused, and the transfer mechanism moves towards the first frame 7. At this time, the two pallets 11 are in the closed state until they are located on the outer sides of the first frame 7, and the first slot 8 of the first frame 7 and the second slot 12 on the two pallets 11 are aligned. The second frame 10 of the transfer mechanism rises, driving the two pallets 11 to rise and lifting the steel sheet 4 above the first frame 7, completing the first transfer. Then, the transfer mechanism moves towards the locking mechanism, the first frame 7 retracts, and the steel sheet 4 is arranged again. The transfer mechanism moves to the first pressure plate 13 and the second pressure plate 1 of the locking mechanism. After four intervals, the two support plates 11 open to support the steel sheet 4 near both ends. The first pressure plate 13 and the second pressure plate 14 extend simultaneously to press down on both ends of the steel sheet 4, causing the steel sheet 4 to bend into a large arc shape. At this time, the distance between the two ends of the steel sheet 4 is less than or equal to the distance between the two inner sides of the lower end of the steel sheet support frame 15. After the first pressure plate 13 and the second pressure plate 14 extend, their inner sides are flush with the inner edge of the lower end of the steel sheet support frame 15. The second frame 10 rises again and pushes the steel sheet 4 upward, so that both ends of the steel sheet 4 are respectively inserted into the insertion slots on both sides of the steel sheet support frame 15, completing the second transfer. Because the steel sheet 4 is inserted... The steel sheet support frame 15 is always limited by the second slot 12, and the steel sheets 4 inserted into the steel sheet support frame 15 are still set at equal distances. After the steel sheets 4 are inserted and the second frame 10, the first pressure plate 13 and the second pressure plate 14 are all reset, the bracket of the output mechanism 2 extends between the second frame 10 and the steel sheet support frame 15, the limiting rod 18 retracts, the bracket rises and lifts the steel sheet support frame 15 to remove it from the limit and then transport it to the top of the output mechanism 2 to complete one loading. The transfer mechanism that has completed the transfer moves to the arrangement mechanism again to transfer the steel sheets 4 that continue to be arranged on the first frame 7 again.

[0053] In another embodiment, combined Figure 1-3 As shown, the first pushing mechanism 5 and the second pushing mechanism 6 are both cylinders. The piston rod of the cylinder extends and retracts to push the steel sheet 4 to move or move downward. The extension or lifting of the telescopic rod, the first pressure plate 13, the second pressure plate 14, the second frame 10, and the bracket are all driven by cylinders.

[0054] In another embodiment, combined Figure 1 , 2As shown in Figure 4, a limiting plate 19 is provided on one side of the inclined plate 3 to facilitate the alignment of one end of the steel sheet 4; a guide plate 20 is also provided on the lower end of the inclined plate 3 to prevent the steel sheet 4 from tipping over or tilting when it moves downward along the inclined plate 3.

[0055] In another embodiment, combined Figure 2 and Figure 5 As shown, the top of the first frame 7 has a pair of protrusions, and the first slots 8 are respectively set on the top of the two protrusions to make it easier for the steel sheet 4 to be inserted and to prevent the steel sheet 4 from getting stuck in the first slots 8.

[0056] In another embodiment, such as Figure 3 As shown, a first guide rail 21 is provided on the frame 1 below the inclined plate 3. A first lead screw mechanism driven by a stepper motor 22 is provided at the end of the first guide rail 21. The first frame 7 is movably connected to the first guide rail 21 and connected to the lead screw of the first lead screw mechanism.

[0057] In another embodiment, combined Figure 1-3 As shown, the frame 1 is also provided with a second guide rail 23 and a second lead screw mechanism 25 driven by a servo motor 24 in the middle. The movable seat 9 is movably connected to the second guide rail 23 and connected to the lead screw of the second lead screw mechanism 25.

[0058] In another embodiment, combined Figure 1 and Figure 2 As shown, an auxiliary support rod 26 is also provided on the second frame 10 on the outer side of the two pallets 11. When the transfer mechanism takes the arranged steel sheet 4 from the arrangement mechanism, the two pallets 11 are in the closed state, and the two ends of each steel sheet 4 rest on the auxiliary support rod 26 to prevent the steel sheet 4 from being displaced or falling off due to vibration during the transfer process.

[0059] In another embodiment, combined Figure 2 and Figure 3 As shown, a forward and reverse motor is fixed to the top of the second frame 10. A slide rail 27 is connected between the two ends of the two auxiliary support rods 26. The two support plates 11 are slidably connected to the two slide rails 27 by sliders. A rack 28 is fixed to the middle of the two support plates 11. A gear 29 is set and fixed in the output axis of the forward and reverse motor. The two racks 28 are respectively meshed on both sides of the gear 29 to make the opening and closing of the two support plates 11 smoother and more stable.

[0060] In another embodiment, such as Figure 6 As shown, the edge width of the upper end of the slot in the steel sheet support frame 15 is greater than the edge width of the lower end of the slot, so as to prevent the steel sheet 4 from being directly ejected from the steel sheet support frame 15 during the process of being pushed and inserted.

[0061] In another embodiment, such as Figure 3 As shown, the bracket is composed of two plates with hooks at the front ends. On the one hand, this reduces the weight of the bracket, and on the other hand, the plates with hooks at the front ends can prevent the steel plate support frame 15 on top of it from falling off.
