Description

Technical Field

[0001] The present invention relates to the technical field of pasting a heating plate and an HOD plate, and in particular to a pasting device for a steering wheel heating plate and an HOD plate. Background Art

[0002] The steering wheel system is a passive safety protection system. During the processing of the steering wheel leather ring, it is necessary to stick a heating plate and a HOD plate on the steering wheel leather ring. Generally, three people are required to stick the heating plate and the HOD plate on the steering wheel leather ring: two people pull open the ring, and one person sticks the heating plate and the HOD plate.

[0003] When the existing steering wheel leather ring is used to stick heating plates and HOD plates, three people are required to operate, which means that each worker needs to perform heavy and repetitive work, which can easily lead to fatigue and reduced efficiency, and reduce production speed. In addition, the manual sticking process relies on the worker's operating accuracy, which can easily lead to position deviation of the heating plate or HOD plate, uneven or loose sticking, affecting the heating effect and product quality. Therefore, a sticking device for steering wheel heating plates and HOD plates is provided. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a bonding device for a steering wheel heater sheet and an HOD sheet, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for pasting steering wheel heating sheets and HOD sheets, comprising a processing table, both sides of the top of the processing table are provided with spreading components for spreading the steering wheel leather ring, the spreading components comprising a side frame 1, a table, and an electric push rod, the side frame 1 is fixed to the top of the processing table, the side of the side frame 1 away from the center of the processing table is rotatably installed with a roller 1, the fixed end of the electric push rod is fixed to the top of the processing table, the telescopic end of the electric push rod is fixed with a side frame 2, the side of the side frame 2 away from the center of the processing table is rotatably installed with a roller 2, the table is fixed to the top of the processing table by a bracket, and the table is located between roller 1 and roller 2, and the top of the processing table is fixed with a useful The driving button is used to control the opening and closing of the electric push rod, and the driving button and the electric push rod are electrically connected to put the steering wheel leather ring on the outside of roller one and roller two, and the electric push rod is started by the driving button. The telescopic end of the electric push rod pushes the side frame two to move along the top of the processing table in the direction away from the side frame one, and the side frame two drives the roller two to move accordingly, so that roller one and roller two stretch and flatten the steering wheel leather ring. A pasting device is provided in the middle of the top of the processing table, and the pasting device includes a T-shaped frame fixed to the top of the processing table, a spraying assembly provided on the top of the processing table, and four Z-shaped groove plates respectively fixed on the front and rear sides of both sides of the T-shaped frame, and the outside of the Z-shaped groove plate is provided with symmetrically arranged Z-shaped grooves, and the outer walls of the four Z-shaped groove plates are The cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench, and the cam is fixed on the top of the workbench A material loading plate is fixed between the two ends of the material loading plate, and pads are fixed on both sides of the bottom of the material loading plate, and the height of the pads is three centimeters. Several material loading openings are opened on the side of the material loading plate, and spring plates are fixed at the four corners of the inner wall below the material loading openings. A branch rod is fixed between the outer walls of the fixed ends of the two elastic telescopic rods away from the center of the processing table, and the branch rod is composed of a cross bar and several vertical rods. The cross bar is fixed between the outer walls of the fixed ends of the two elastic telescopic rods, and several vertical rods are evenly and equidistantly fixed at the bottom of the cross bar. Several push blocks are fixed at the bottom of the vertical rod of the branch rod, and the push blocks are slidably installed inside the material loading opening of the material loading plate. A connecting plate 1 is fixed between the two spray plates corresponding to the two slide plates, and a connecting plate 2 is fixed between the two material loading plates corresponding to the two slide plates.When the cam is released, the two slides corresponding to the two glue spraying plates are pushed downward, and the slides push the elastic telescopic rods and the sliding column to move downward. Since the movement trajectory of the sliding column is restricted by the Z-shaped groove of the Z-shaped groove plate, the Z-shaped groove of the Z-shaped groove plate pushes the sliding column to drive the fixed end of the elastic telescopic rod to move along the bottom of the slide plate toward the center of the Z-shaped groove plate, so that the slide corresponding to the glue spraying plate is driven by the elastic telescopic rod to move downward and also move toward the center of the Z-shaped groove plate until the glue spraying plate moves to the top position of the steering wheel leather ring. Then, the pump is started, and the glue liquid in the glue tank is extracted by the pump and transmitted to the glue spraying plate through the hose for spraying. The glue spraying plate will spray the glue on the surface of the steering wheel leather ring. After that, the staff manually releases the connecting plate, and the connecting plate is reset under the elastic force of the corresponding supporting spring. , so that the connecting plate 1 drives the glue spraying plate to reset and move upward through the slide plate and the elastic telescopic rod. Then, the staff manually pulls the connecting plate 2 downward, and the connecting plate 2 drives the two slide plates corresponding to the two material feeding plates to move downward. The slide plates corresponding to the material feeding plates drive the material feeding plates to move downward through the elastic telescopic rod, and at the same time, they move toward the center of the Z-shaped groove plate until the material feeding plates move to the top position of the steering wheel leather ring. At this time, the material feeding plate and the steering wheel leather ring are stationary. As the staff continues to pull the connecting plate 2 downward, the connecting plate 2 pushes the fixed end of the elastic telescopic rod to continue to move downward. The fixed end of the elastic telescopic rod pushes the branch rod to drive the push block downward. The push block pushes the heating plate or HOD plate in the material feeding port of the material feeding plate to move downward. The heating plate or HOD plate passes over the spring plate and is pressed against the position of the glue sprayed by the glue spraying plate, so that the heating plate or HOD plate is adhered to the outside of the steering wheel leather ring.

[0006] According to the above technical solution, a feeding device is provided at the material placement plate, and the feeding device includes a multi-port plate, which is fixed on the side of the T-shaped frame away from the center of the processing table, and a plurality of cover plates are evenly and equidistantly fixed on the side of the multi-port plate away from the center of the processing table. A limiting rod is fixed on the bottom of the multi-port plate, and a T-shaped plate is slidably installed on the outside of the limiting rod, and a spring is provided between the T-shaped plate and the limiting rod. A plurality of push plates are evenly and equidistantly fixed on the side of the T-shaped plate close to the multi-port plate, and the push plate passes through the outer wall of the multi-port plate, and the bottom of the push plate It is on the same horizontal plane as the top of the spring piece. Every time the heating piece or HOD piece in the feeding plate is pushed out of the feeding port of the feeding plate by the push block, when the heating piece or HOD piece in the feeding port of the feeding plate needs to be replenished, the staff manually pushes the T-shaped plate, and the T-shaped plate moves along the outside of the limit rod toward the cover plate. The T-shaped plate pushes the push plate to move along, and the push plate pushes the heating piece or HOD piece in the multi-port plate to move to the inside of the feeding port of the feeding plate, and the heating piece or HOD piece is located on the top of the spring piece, thereby completing the replenishment of the heating piece or HOD piece.

[0007] The two cams are connected by a hinged joint, and the hinged joints are connected multiple times by a hinged joint, and the hinged joints are connected multiple times by a hinged joint. The column protrudes one centimeter from the Z-shaped groove of the Z-shaped groove plate, and the middle fixed end of the two-way telescopic rod is located on the movement trajectory of the sliding column. Each time the sliding column moves downward and moves to the top position of the fixed end of the two-way telescopic rod, the sliding column pushes the top of the two-way telescopic rod to drive the two-way telescopic rod to move downward along the outside of the I-shaped rod. First, the two-way telescopic rod pushes the center plate downward through the hinged rod, and the center plate drives the connecting column to move downward along the inside of the transverse plate. After the center plate contacts the top of the table, the center plate and the table are stationary relative to each other. As the two-way telescopic rod continues to move downward, the two-way telescopic rod pushes the center plate toward the center of the table through the hinged rod, and the center plate pushes the steering wheel leather ring sleeve on the outside of roller one and roller two to be centered on the table.

[0008] According to the above technical solution, a pressing device is provided at one of the rollers, and the pressing device includes an elastic telescopic plate, the fixed end of the elastic telescopic plate is fixed at the outer wall of the side frame, and the telescopic end of the elastic telescopic plate is rotatably installed with a pressing roller, and the pressing roller contacts the outer wall of the roller, and the pressing roller is arranged in a semicircular shape on the side away from the center of the processing table. When one side of the heating plate or the HOD plate is pasted, the staff manually rotates the roller, and the roller drives the steering wheel leather ring to rotate, so that the side of the steering wheel leather ring that is not pasted with the heating plate or the HOD plate is rotated to the table position, and the side of the steering wheel leather ring that is pasted with the heating plate or the HOD plate will pass through the pressing roller during the movement, and the pressing roller will always be against the outer wall of the roller under the elastic force of the elastic telescopic plate, so that the pressing roller will press the heating plate or the HOD plate during the movement.

[0009] The present invention provides a device for attaching steering wheel heaters and HOD sheets. It has the following beneficial effects:

[0010] (1) The present invention sets up a pasting device, so that the stretching assembly, connecting plate 1, glue spraying plate, slide plate, elastic telescopic rod, sliding column, Z-shaped groove plate, glue spraying plate, glue spraying assembly, connecting plate 2 and material placement plate cooperate, and the push block pushes the heating plate or HOD plate in the material placement port to move downward, the heating plate or HOD plate passes over the elastic plate, and the heating plate or HOD plate is pressed at the position of the glue sprayed by the glue spraying plate, so that the heating plate or HOD plate is pasted on the outside of the steering wheel leather ring. By spraying glue on the glue spraying plate and pasting the heating plate or HOD plate on the material placement plate, the staff only needs to perform simple manual operations to realize the pasting operation of the heating plate and the HOD plate. It is no longer necessary to perform long-term and repeated heavy manual operations, which significantly reduces the labor intensity and avoids the errors that may occur in manual operations, ensuring that the pasting effect of the heating plate or HOD plate of each steering wheel leather ring is consistent, and improving product quality.

[0011] (2) The present invention sets up a feeding device so that the T-shaped plate, the limiting rod, the cover plate and the push plate cooperate to push the heating plate or HOD plate in the multi-port plate to move to the inside of the feeding port of the feeding plate, and the heating plate or HOD plate is located on the top of the spring plate, thereby completing the replenishment of the heating plate or HOD plate. This replenishment method can greatly reduce the time of manual operation, so that the heating plate or HOD plate can be replenished to the feeding port of the feeding plate more quickly, while avoiding the delay of manual operation and improving the overall work efficiency.

[0012] (3) The present invention sets a positioning device so that the sliding column, the two-way telescopic rod, the I-shaped rod, the hinged rod, the connecting column and the transverse plate cooperate to push the centering plate to move toward the center of the table. The centering plate pushes the steering wheel leather ring sleeve on the outside of the roller one and the roller two to be centered on the table, thereby ensuring that the steering wheel leather ring sleeve is located at the lower landing point of the spray plate and the material placement plate, thereby avoiding the steering wheel leather ring from being partially glued and not properly pasted to the heating plate or HOD plate due to inaccurate positioning, thereby reducing the generation rate of defective products and reducing the rework rate.

[0013] (4) The present invention sets a pressing device. The pressing roller is always pressed against the outer wall of roller one under the elastic force of the elastic telescopic plate, so that the pressing roller presses the heating plate or HOD plate during the movement. Appropriate pressing can promote a more even distribution of the glue of the heating plate or HOD plate, enhance the adhesion between the glue and the surface of the leather ring, ensure that the heating plate or HOD plate is firmly adhered to the steering wheel leather ring, and improve its durability and service life. At the same time, the semicircular setting of the pressing roller makes it easy for the staff to put the steering wheel leather ring on the outside of roller one and roller two. The steering wheel leather ring can easily pass through the pressing roller and enter between the pressing roller and roller one, thereby avoiding the problem that the existence of the pressing roller easily hinders the steering wheel leather ring from being put on the outside of roller one and roller two.

[0029] When in use, the steering wheel leather ring is put on the outside of roller 1 22 and roller 2 24, and the electric push rod 26 is started by the drive button 27. The telescopic end of the electric push rod 26 pushes the side frame 23 to move along the top of the processing table 1 in the direction away from the side frame 1 21, and the side frame 23 drives the roller 2 24 to move accordingly, so that the roller 1 22 and the roller 2 24 stretch and flatten the steering wheel leather ring. The staff manually pulls down the connecting plate 1 310 to move downward, and the connecting plate 1 310 drives the two slides 34 corresponding to the two spray plates 36 to move downward, and the slide 34 pushes the elastic telescopic rod 35 and the sliding column 33 to move downward. Since the movement trajectory of the sliding column 33 is restricted by the Z-shaped groove of the Z-shaped groove plate 32, the Z-shaped groove of the Z-shaped groove plate 32 pushes The sliding column 33 drives the fixed end of the elastic telescopic rod 35 to move along the bottom of the slide plate 34 toward the center of the Z-shaped groove plate 32, so that the slide plate 34 corresponding to the glue spraying plate 36 is driven by the elastic telescopic rod 35 to move downward and also move toward the center of the Z-shaped groove plate 32 until the glue spraying plate 36 moves to the top position of the steering wheel leather ring.

[0033] The roller one 22 is provided with a pressing device 6, the pressing device 6 comprises an elastic expansion plate 61, the fixed end of the elastic expansion plate 61 is fixed at the outer wall of the side frame one 21 (as shown in Figure 11 The elastic expansion plate 61 is rotatably installed with a pressing roller 62 at the expansion end, the pressing roller 62 is in contact with the outer wall of the roller one 22, through the setting of the above structure, the pressing roller 62 is always in contact with the outer wall of the roller one 22 under the action of the elastic force of the elastic expansion plate 61, so that the pressing roller 62 can press the heating sheet or the HOD sheet in the moving process, appropriate pressing can make the glue of the heating sheet or the HOD sheet more evenly distributed, enhance the adhesion of the glue and the surface of the leather cord, ensure that the heating sheet or the HOD sheet is firmly adhered to the leather cord of the steering wheel, improve its durability and service life, the side of the pressing roller 62 away from the center of the processing table 1 is semi-circular, and the semi-circular setting of the pressing roller 62 makes the leather cord of the steering wheel easy to pass through the pressing roller 62 and enter between the pressing roller 62 and the roller one 22 when the leather cord of the steering wheel is sleeved outside the roller one 22 and the roller two 24, thereby avoiding the problem that the existence of the pressing roller 62 easily hinders the leather cord of the steering wheel from being sleeved outside the roller one 22 and the roller two 24.

[0034] In use, each time the slide column 33 moves downward, when the slide column 33 moves to the top position of the fixed end of the bidirectional expansion rod 52, the slide column 33 pushes the top of the bidirectional expansion rod 52 to drive the bidirectional expansion rod 52 to move downward along the outside of the I-shaped rod 51, first, the bidirectional expansion rod 52 pushes the centering plate 56 downward through the hinged rod 55, the centering plate 56 drives the connecting column 54 to move downward along the inside of the transverse plate 53, after the centering plate 56 contacts the top of the table 25, the centering plate 56 and the table 25 are stationary relative to each other, as the bidirectional expansion rod 52 continues to move downward, the bidirectional expansion rod 52 pushes the centering plate 56 to move towards the center of the table 25 through the hinged rod 55, the centering plate 56 pushes the leather cord set of the steering wheel sleeved outside the roller one 22 and the roller two 24 to be centered at the table 25, thereby ensuring that the leather cord set of the steering wheel is located at the downward landing point of the glue spraying plate 36 and the material placing plate 37, thereby avoiding the problem that the partial glue of the leather cord of the steering wheel is not glued and the heating sheet or the HOD sheet is not pasted in place due to inaccurate position, thereby reducing the generation rate of defective products and reducing the rework rate.

[0035] When the heating sheet or the HOD sheet is pasted on one side, the staff manually rotates the roller 22, and the roller 22 drives the steering wheel leather cover to rotate, so that the side of the steering wheel leather cover which is not pasted with the heating sheet or the HOD sheet is rotated to the table 25 position, and the side of the steering wheel leather cover which is pasted with the heating sheet or the HOD sheet moves through the pressing roller 62. The pressing roller 62 is always in contact with the outer wall of the roller 22 under the elastic force of the elastic expansion plate 61, so that the pressing roller 62 can press the heating sheet or the HOD sheet during movement. Proper pressing can make the glue of the heating sheet or the HOD sheet more evenly distributed, enhance the adhesion of the glue and the surface of the cover, ensure that the heating sheet or the HOD sheet is firmly adhered to the steering wheel leather cover, improve its durability and service life, and at the same time, the semi-circular arrangement of the pressing roller 62 makes it easy for the staff to put the steering wheel leather cover on the outside of the roller 22 and the roller 24, and the steering wheel leather cover is easily put through the pressing roller 62 into the space between the pressing roller 62 and the roller 22, so that the existence of the pressing roller 62 does not easily hinder the steering wheel leather cover from being put on the outside of the roller 22 and the roller 24.
