Description

Technical Field

[0001] The invention relates to an automatic turning over and glue spraying system and method for a metal workpiece, belonging to the technical field of rubber-metal composite workpiece preparation. Background Art

[0002] Rubber-metal composite products are widely used in rail vehicles, engineering machinery, ships, aviation and other fields due to their combination of the advantages of high elasticity of rubber and high strength of metal. The adhesion between the two is the key to product quality. Metal parts are cleaned to remove oil stains, sandblasted to increase the specific surface area, and then glue is applied to achieve good infiltration of the adhesive on the metal surface. Currently, double-coating adhesives are used, which are completed through loading → applying primer → drying → applying top glue → drying → unloading. For workpieces that need to be glued on both sides, the process is to load → apply primer on side A → drying → flip to side B → apply primer on side B → drying → apply top glue on side B → drying → flip to side A → apply top glue on side A → drying → unloading. It requires 2 primer spray booths, 2 top glue spray booths, and 4 drying booths. The problems are:

[0003] 1. Spraying on both sides of the bottom requires four spray booths and four drying booths, which takes up a large area and has high costs for wastewater and waste gas treatment.

[0036] The following combination Figures 1 to 9 The embodiments of the present invention are described in detail.

[0037] 3. The automatic turning over and gluing system for metal workpieces is characterized in that: it includes two groups of spraying and drying mechanisms, one group of spraying and drying mechanisms is set as a base glue spraying and drying mechanism, and the other group of spraying and drying mechanisms is set as a surface glue spraying and drying mechanism, and the spraying and drying mechanisms each include a drying warehouse 1 and a spray room 2 opposite to the drying warehouse 1, the spray room 2 in the base glue spraying and drying mechanism is connected to the drying warehouse 1 in the surface glue spraying and drying mechanism through an intermediate conveyor belt 3, the spray room 2 in the surface glue spraying and drying mechanism is connected to a discharge drying channel 4, the drying warehouse 1 is equipped with a circulating motion machine 5 that can drive a tool 1001 with a hollow structure and a workpiece 101 placed on the tool to move to each station, a telescopic table 6 that can move back and forth between the drying warehouse 1 and the spray room 2, and a turning machine 7 that can drive the workpiece to turn over, and the spray room 2 is equipped with a sprayer 8 for spraying glue on the workpiece and a tool that can lift, rotate and translate the tooling and workpiece The rotating jacking and translation table 9, the circulating motion machine 5 has a loading station 51, a flow drying station 52, a telescopic docking station 53, a flipping station 54 and a flip receiving station 55 distributed in a closed path in the vertical direction. The tooling workpiece is placed on the loading station 51 and moves to each station with the circulating motion machine 5. The telescopic table 6 is arranged on the side of the telescopic docking station 53, driving the tooling workpiece on the telescopic docking station 53 to move back and forth between the relatively arranged drying warehouse 1 and the spray room 2. The flipping machine 7 is arranged on the side of the flipping station 54, driving the workpiece on the flipping station 54 to flip over and place the workpiece on the tooling moved to the flip receiving station. The rotating jacking and translation table 9 corresponds to the telescopic docking station 53 one by one. The tooling workpiece enters the spray room 2 with the telescopic table 6 and is vertically aligned with the rotating jacking and translation table 9. The sprayer 8 is located above the rotating jacking and translation table 9.

[0038] The automatic flipping and gluing system for metal workpieces described above comprises two groups of spraying and drying mechanisms. The circulating motion machine 5 in the spraying room 2 of the spraying and drying mechanism drives the tooling workpiece to move to each station. The telescopic table 6 drives the tooling workpiece on the telescopic docking station 53 to move back and forth between the drying room 1 and the spraying room 2. The flipping machine 7 drives the workpiece to flip over. The flipping receiving station 55 receives the flipped workpiece. By moving the workpiece back and forth between the spraying room 2 and the drying room 1 and flipping it in the drying room 1, the spraying of primer or surface glue on both sides is realized. The primer spraying on both sides shares one spraying room, and the surface glue spraying on both sides shares one spraying room. Only two spraying rooms are needed to complete the spraying of double-sided primer and surface glue, which is much simpler than the existing ones. The number of four spray booths in the existing technology is reduced by half; the two spray drying mechanisms are connected by an intermediate conveyor belt 3 to realize the transmission of the workpiece sprayed with the primer to the surface glue spray drying mechanism, and the spray booth 1 in the surface glue spray drying mechanism is connected to the discharging drying channel 4, and the surface glue is dried while discharging. The setting of the two drying warehouses and the discharging drying channel realizes the drying after four spraying, reduces the number of drying warehouses and realizes the discharging and drying simultaneously, and simplifies the production process; the reduction in the number of drying warehouses 1 and spray booths 2 effectively reduces the floor space, reduces the treatment cost of waste gas and wastewater, improves production efficiency, improves the automation level of metal workpiece spraying, reduces manual labor intensity and cost, and ensures the stability of spraying quality.

[0039] Among them, the circulating motion machine 5 includes a workstation frame 10 installed in the drying warehouse along the vertical direction, two vertically aligned and rotatable sprockets 11 installed on the workstation frame 10, a chain 12 assembled on the two sprockets 11, a motor 13 driving one of the sprockets 111 to rotate counterclockwise, and a support frame 14 installed on the chain 12. The tooling 100 is placed on the support frame 14. There are two telescopic docking stations 53 and they are horizontally aligned. The tooling workpiece enters from the loading station 51 and passes through each station with the movement of the sprocket. The motor 13 in the circulating motion machine 5 drives the sprocket 11 to rotate counterclockwise, driving the chain 12 to move, and the chain 12 drives the other sprocket 11 to rotate synchronously. The support frame 14 moves synchronously with the chain 12. The tooling 100 is placed on the support frame 14 to form a work station. The tooling workpiece moves to each work station with the support frame 14 and completes the corresponding operation at each work station. The tooling workpiece is loaded from the loading station 51 in turn and moves to each work station with the circulating motion machine 5, so that each work station has a tooling workpiece. Multiple tooling workpieces perform the corresponding operations at their respective work stations synchronously, realizing synchronous processing of multiple workpieces and high production efficiency.

[0040] The telescopic platform 6 comprises a platen 61 positioned in front of the two telescopic docking stations and a motorized telescopic rod 62 mounted on the station frame 10 and capable of moving the platen 61 back and forth between the spray booth 2 and the drying chamber 1. The platen 61 has upwardly protruding rectangularly arranged protrusions 63, and the tooling 100 has two circular holes 102 for engaging the protrusions. As shown in the figure, the tooling 100 has two circular holes 102 at its bottom, and the platen 61 has four rectangularly arranged protrusions 63. Two of these protrusions 63 correspond to the circular holes 102 at the bottom of the tooling on one telescopic docking station 53, while the other two protrusions 63 correspond to the circular holes 102 at the bottom of the tooling on the other telescopic docking station 100. The movement of the motorized telescopic rod 62 drives the workpieces of the two tools into the spray booth 2 synchronously, with the workpiece on one tooling being sprayed on the front side and the workpiece on the other tooling being sprayed on the back side, thereby improving production efficiency.

[0041] The flipping machine 7 includes a vertical linear module 71 mounted on the top of the work station frame 10 and above the flipping station, a horizontal linear module 72 mounted on the vertical linear module 71, and a flipping suction cup 73 mounted on the horizontal linear module 72. The vertical linear module 71 drives the horizontal linear module 72 and the flipping suction cup 73 to move vertically, and the horizontal linear module 72 drives the flipping suction cup 73 to move horizontally. The flipping suction cup 73 can adsorb the workpiece and perform a 180-degree flip. When the workpiece moves to the flipping station 54, the flipping suction cup 73 is driven by the horizontal linear module 72 and the vertical linear module 71 to the bottom of the tooling and extends into the tooling to adsorb the bottom surface of the workpiece. Then, the flipping suction cup 73 is driven by the vertical linear module 71 to lift the workpiece upward, so that the workpiece is lifted above the tooling, and then The workpiece and the flip suction cup 73 are driven to move horizontally by the horizontal linear module 72 so that the flip suction cup 73 is moved horizontally out of the tooling, and then the flip suction cup 72 is flipped 180 degrees to turn the workpiece over. At the same time, the tooling of the flipping station 54 is moved to the flipping receiving station 55. After the workpiece is flipped over, it is located above the tooling of the flipping receiving station 55. The flip suction cup 72 is released to adsorb the workpiece so that the turned workpiece is placed back on the tooling. The flipping machine 7 flips the workpiece, thereby realizing spraying on both sides of the workpiece in one spray room.

[0042] Among them, the spray booth 2 is provided with a spraying station 21 corresponding to the telescopic docking station 53, the sprayer 8 is arranged above the painting station 21, and the rotating lifting and translation platform 9 is arranged directly below the painting station 21. The rotating lifting and translation platform 9 includes a frame 91, an electric lifting platform 93 mounted on the frame, an electric turntable 92 mounted on the electric lifting platform 93, and a translation conveyor belt 94 mounted on the frame and horizontally arranged. When the table 61 and the tooling workpiece enter the spray room 2 together, the electric lifting platform 93 extends into the tooling 100 to lift the tooling workpiece and separate it from the table 61. The electric turntable 92 drives the tooling workpiece to rotate one circle, and the sprayer 8 sprays glue on the tooling. After spraying, the tooling workpiece on the spraying station where the glue is sprayed on the front of the workpiece is placed back on the table 61 by the electric lifting platform 93 and moved back to the drying warehouse as the telescopic table 6 returns to its original position. After spraying, the tooling workpiece on the spraying station where the glue is sprayed on the back of the workpiece is lowered by the electric lifting platform 93 and placed on the translation conveyor belt 94. It is transmitted to the intermediate conveyor belt or the discharging drying channel by the translation conveyor belt 94 to form the discharging material after spraying.

[0043] The sprayer 8 includes an X-axis linear module 81 arranged horizontally, a Y-axis linear module 82 mounted on the X-axis linear module 81 and arranged horizontally, a Z-axis linear module 83 mounted on the Y-axis linear module 82 and arranged vertically, a spray gun holder 84 mounted on the Z-axis linear module 83, and a spray gun 85 mounted on the nozzle holder 84. The sprayer 8 is mounted above the spray station 21. The X-axis linear module 81 and the Y-axis linear module 82 are both arranged horizontally, and the Z-axis linear module 83 is arranged vertically, so that the spray gun 85 can move forward and backward, left and right, and up and down to ensure effective spraying of the workpiece surface.

[0044] The two rotating lifting and translating platforms 9 in the spray booth 2 are of different heights: one rotating lifting and translating platform 9 is horizontally aligned with the intermediate conveyor belt 3, and the other rotating lifting and translating platform 9 is horizontally aligned with the discharge drying tunnel 4. In the spray booth of the primer spraying and drying mechanism, one rotating lifting and translating platform 9 is aligned with the intermediate conveyor belt 3. After the reverse side primer spraying is completed, the tooling workpiece is transferred to the intermediate conveyor belt 3 via the rotating lifting and translating platform 9. The intermediate conveyor belt 3 transfers the tooling workpiece to the drying storage loading station of the top glue spraying and drying mechanism. In the spray booth of the top glue spraying and drying mechanism, one rotating lifting and translating platform 9 is aligned with the discharge drying tunnel 4. After the reverse side primer spraying is completed, the tooling workpiece is transferred to the discharge drying tunnel 4 via the rotating lifting and translating platform 9 for discharge and drying.

[0045] The present invention also protects a method for automatically turning over and spraying glue on a rubber-metal composite workpiece, which uses the above-mentioned automatic turning over and spraying glue system for metal workpieces, and is characterized in that the spraying step includes:

[0046] S1: placing the tooling workpiece into the loading station 51 of the drying warehouse 1 in the primer spraying and drying mechanism and moving with the circulating motion machine 5;

[0047] S2: The workpiece moves to the telescopic docking station 53 and enters the spray booth 2 driven by the telescopic platform 6. The base glue is formed on the front of the workpiece by the lifting and rotation of the rotating lifting and translation platform 9 and the spraying of the sprayer 8;

[0048] S3: The workpiece moves back to the drying room 1 as the telescopic table 6 returns to its original position to dry the front glue, and then moves to the flipping station 54. The flipping machine 7 adsorbs, lifts, removes, and flips the workpiece on the tooling, and then places the workpiece on the tooling that moves to the flipping receiving station 55.

[0049] S4: The workpiece moves to another telescopic docking station 53 and enters the spray booth 2 driven by the telescopic platform 6. With the rotation and lifting of the rotating jacking and translation platform 9 and the spraying of the sprayer 8, a primer is formed on the back of the workpiece.

[0050] S5: The tooling workpiece is moved to the loading station 51 of the drying warehouse 1 in the surface glue spraying and drying mechanism by rotating the jacking and translation platform 6 and the intermediate conveyor belt 3, and the back glue is dried with the movement of the circulating motion machine. The tooling workpiece moves to the telescopic docking station 53 and enters the spraying room 2 driven by the telescopic platform 6. With the rotation and jacking of the rotating jacking and translation platform 9 and the spraying of the sprayer 8, the back glue is formed on the workpiece.

[0051] S6: The workpiece moves back to the drying room 1 to dry the back surface adhesive as the telescopic table 6 returns to its original position, and then moves to the flipping station 54. The flipping machine 7 adsorbs, lifts, removes, and flips the workpiece on the tooling, and then places the workpiece on the tooling that moves to the flipping receiving station 55.

[0052] S7: The tooling workpiece moves to another telescopic docking station 53, and enters the spray room 2 driven by the telescopic table 6. With the rotation and lifting of the rotating jacking and translation table 9 and the spraying of the sprayer 8, the surface glue is formed on the front of the workpiece;

[0053] S8: Move the tooling workpiece to the discharge drying channel 4 by rotating the lifting and translation platform 9 to discharge and dry it.

[0054] The automatic flipping and spraying method of the rubber-metal composite workpiece described above realizes the spraying of primer or surface glue on both sides. The primer spraying on both sides shares one spray room, and the surface glue spraying on both sides shares one spray room. Only two spray rooms are needed to complete the spraying of double-sided primer and surface glue, which is half the number of four spray rooms in the prior art. The two spraying and drying mechanisms are connected by an intermediate conveyor belt 3 to realize the transmission of the workpiece sprayed with primer to the surface glue spraying and drying mechanism, and the spray room 1 in the surface glue spraying and drying mechanism is connected to the discharging drying channel 4 to dry the surface glue while discharging. The setting of the two drying warehouses and the discharging drying channel realizes drying after four sprayings, reduces the number of drying warehouses and realizes discharging and drying simultaneously, simplifying the production process. The reduction in the number of drying warehouses 1 and spray rooms 2 effectively reduces the floor space, reduces the cost of treating waste gas and wastewater, improves production efficiency, improves the automation level of metal workpiece spraying, reduces manual labor intensity and cost, and ensures the stability of spraying quality.

[0055] Among them, "moving the tooling workpiece to the loading station 51 of the drying warehouse 1 in the surface glue spraying and drying mechanism by rotating the jacking and translating platform 9 and the intermediate conveyor belt 3" in step S5 means that after the base glue is formed on the back of the workpiece, the jacking and translating platform 9 is rotated to adjust the tooling workpiece to the height of the intermediate conveyor belt 3, and the translation conveyor belt 94 of the jacking and translating platform 9 is rotated to move the tooling workpiece onto the intermediate conveyor belt 3, and the intermediate conveyor belt 3 conveys the tooling workpiece to the loading station 51 of the drying warehouse 1 in the surface glue spraying and drying mechanism. After the base glue spraying on both sides of the workpiece is completed, the intermediate conveyor belt 3 is used to convey the tooling workpiece to the surface glue spraying and drying mechanism for surface glue spraying, thereby realizing automatic unloading from the bottom spraying and drying mechanism to loading into the surface glue spraying and drying mechanism, and high production efficiency.

[0056] Specifically, step S8 involves rotating the lifting and translating platform to adjust the workpiece to the height of the discharge drying tunnel after the glue is applied to the front side of the workpiece. The lifting and translating platform 9 then rotates the translation conveyor belt 94 to move the workpiece to the discharge drying tunnel 3, drying the glue on the front side while discharging the workpiece. Once the glue is applied to both sides of the workpiece, the discharge drying tunnel 3 simultaneously dries the glue on the back side and discharges the workpiece, streamlining the production process and increasing production efficiency.

[0057] The above fully describes the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the embodiments described are only part of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
