Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile seat production process, and particularly relates to a sound-absorbing cloth laying device and laying method for an automobile seat foaming mold. BACKGROUND

[0002] In the process of manufacturing automobiles, the foaming mold of a seat is an important tool for manufacturing the seat. The mold moves along with the production line on the production line. Before the seat is foamed, a layer of sound-absorbing cloth needs to be laid on the mold to improve the sound insulation effect and the comfort of the seat. In actual production, an isolation baffle is fixedly arranged between the workstations of the automobile seat production line to avoid the danger of workers intruding into the flowing production line. A tray for placing the sound-absorbing cloth is arranged on the isolation baffle. However, the types of molds flowing on the production line are different (because even for the same batch of vehicles, the front seats and the rear seats in the vehicles are not the same, and therefore the foaming molds for manufacturing the seats are also different, and the sizes of the sound-absorbing cloths used for different foaming molds are also different), and therefore, the isolation baffle beside the production line is not enough to place multiple trays to meet the actual production needs, and therefore, a table needs to be arranged beside the isolation baffle to place the trays for placing different sound-absorbing cloths.

[0003] However, the conventional sound-absorbing cloth laying method often relies on manual operation, that is, the sound-absorbing cloth is manually taken and hung on the hooks of the foaming mold (so that the sound-absorbing cloth is pierced by four hooks to be hung on the hooks). This method is very inefficient, and the molds on the production line are continuously moving, which requires multiple workers to lay the sound-absorbing cloth, greatly increasing the labor cost. Moreover, the manual laying of the sound-absorbing cloth is easily affected by human factors, resulting in uneven laying or inaccurate position of the sound-absorbing cloth, thereby affecting the quality and performance of the seat.

[0017] The application further provides a sound-absorbing cloth laying method for a car seat foaming mold.

[0018] First, the stacked sound-absorbing cloths are placed in the respective trays arranged beside the production line, the car seat foaming mold on the production line moves to the production line, and an industrial camera monitors the shape of the car seat foaming mold and the positions of the four hanging nails on the mold.

[0019] The controller automatically controls the start of the speed reducer motor in the direction adjusting mechanism, drives the second rotating shaft to rotate, thereby driving the rectangular block to rotate, and thereby driving the four suction cups to move towards the sound-absorbing cloths in the trays beside the production line through the distance adjusting mechanism.

[0020] Then, the two first push rod motors are automatically started synchronously, the output rods are elongated, the four suction cups are lowered, and the sound-absorbing cloths on the uppermost layer in the trays are pressed, the output rods of the first push rod motors are continuously elongated, the mounting blocks are continuously lowered, the first springs are compressed, the sliding ring blocks press the first sheet type pressure sensor, when the pressure reaches a set pressure value, the negative pressure pump is automatically started through the controller, so that the four mounting cylinders are in a negative pressure state, thereby the suction cups adsorb the sound-absorbing cloths on the uppermost layer.

[0021] Then, the first push rod motor output rod is shortened, the sound-absorbing cloth is adsorbed by the suction cup, and as the suction cup rises, then the deceleration motor is automatically started and reversed, the rectangular block is driven to rotate through the second rotating shaft, so that the four suction cups are turned over to the direction of the mold, and the two second push rod motor output rods are shortened, the four fourth push rod motor output rods are shortened, and the distance of the four suction cups is adjusted so that the positions correspond to the positions of the four hooks on the mold;

[0022] Then, the two rodless cylinders are started to drive the two supporting side plates to move vertically, and the two sliders slide along the two stabilizing rods to adjust the height of the laying mechanism, so that the height positions of the four suction cups correspond to the positions of the four hooks on the mold;

[0023] At the same time, the controller automatically starts the dual-shaft motor to drive the two connecting shafts to rotate, and through the four first bevel gears, the two first rotating shafts are driven to rotate, so that the two spur gears are driven to rotate. Since the two spur gears are engaged with the two racks, the two spur gears move along the racks while rotating, so that the mounting box moves, and the walking wheels on both sides of the mounting box roll on the inner wall of the channel steel track. The movement of the mounting box makes the laying mechanism move synchronously and at the same speed as the mold on the production line;

[0024] At the same time, while the dual-shaft motor is running, the first push rod motor output rod is extended, so that the four suction cups and the sound-absorbing cloth adsorbed thereby move towards the hooks until the sound-absorbing cloth is pierced by the four hooks, and the hooks hinder the continuous movement of the pressure plate in the suction cup. The fixed block continues to move as the first push rod motor output rod continues to extend until the second sheet-type pressure sensor on the fixed block contacts and presses the pressure plate. When the second sheet-type pressure sensor is pressed by the pressure plate to a set value, the controller automatically controls the negative pressure pump to stop running, so that the suction cup loses the adsorption of the sound-absorbing cloth, and at the same time, the two first push rod motors are automatically controlled to start, so that the output rod is shortened, and the suction cup moves away from the hooks to restore the initial state;

[0025] Then, the dual-shaft motor is automatically reversed, so that the mounting box moves in the opposite direction, and the device returns to the initial state;

[0026] When the industrial camera monitors the type of automobile seat foaming mold, and the matched sound-absorbing cloth is placed in the tray on the table, the step motor is started to drive the main gear to rotate, thereby driving the inner tooth ring to rotate, and then driving the middle shaft to rotate through the mounting disc, and the middle shaft drives the vertical pipe to rotate through the circular block, thereby driving the two sleeve plates to rotate by half a turn, so that the suction cup is turned to above the tray on the table. Then, the sound-absorbing cloth can be adsorbed in the above-mentioned manner, and then the suction cup adsorbing the sound-absorbing cloth is directed towards the mold by reversing the step motor, and then the sound-absorbing cloth on the suction cup can be hung on the hooks in the above-mentioned manner, and the initial state is restored.

[0028] The automobile seat foaming mold sound-absorbing cloth laying device and method provided by the present application realizes an efficient, accurate and automated sound-absorbing cloth laying process as a whole, and through the introduction of an industrial camera and a precise control system, the present application can accurately identify the shape and pin position of the mold, thereby ensuring that the sound-absorbing cloth can be accurately laid to the specified position;

[0029] The present application utilizes the orientation adjusting mechanism and the distance adjusting mechanism to flexibly adjust the position and orientation of the suction cup to adapt to different specifications and types of molds, and at the same time, through precise pressure control and negative pressure adsorption technology, the present application can reliably adsorb and fix the sound-absorbing cloth to prevent deviation or falling during the laying process;

[0030] In addition, the present application also adopts an automated driving and control system, which not only improves the production efficiency and reduces the labor cost, but also significantly reduces the errors and defective rates caused by human factors, realizes the efficient, accurate and automated laying of the sound-absorbing cloth for automobile seat foaming molds, and brings significant technical progress and benefit improvement to the automobile seat manufacturing industry.

[0049] In the embodiment, the device aims to solve the problems of low laying efficiency, high labor cost, uneven laying or inaccurate position and the like in the prior art. The bottom plate 1 provided by the device is a fixed base of the whole laying device and provides stable support for other components. The two channel steel tracks 2 are arranged in parallel on the bottom plate 1 and are used for guiding the movement of the mounting box 3. The mounting box 3 is arranged between the two channel steel tracks 2 and serves as a carrier of the walking mechanism. The walking mechanism is arranged on the mounting box 3 and matched with the channel steel tracks 2, and is used for driving the mounting box 3 to move on the tracks. The supporting plate 4 is fixedly mounted on the top of the mounting box 3 and serves as a support platform of the lifting mechanism. The lifting mechanism is assembled on the supporting plate 4 and is used for accurately adjusting the height of the laying assembly according to the height of the sound-absorbing cloth peg of the car seat foaming mold, so as to ensure the accuracy and efficiency of the laying process. The laying assembly is arranged above the supporting plate 4 and is used for performing the laying task of the sound-absorbing cloth to realize automatic grabbing and laying of the sound-absorbing cloth. The laying device improves the laying efficiency and quality of the sound-absorbing cloth of the car seat foaming mold through the characteristics of automation and accurate adjustment. In actual application, the device is expected to significantly improve the overall efficiency of the car seat manufacturing process, reduce the labor cost and improve the product quality.

[0050] The walking mechanism comprises: a double-shaft motor 11 fixedly installed in the mounting box 3 for providing walking power, a connecting shaft 12 fixedly installed on each output shaft of the double-shaft motor 11 through a shaft coupling, a mounting plate 13 fixedly installed on each side of the mounting box 3, a first rotating shaft 14 rotatably installed on each of the mounting plates 13, a first bevel gear 15 fixedly installed at the top end of each of the first rotating shafts 14 and at the end of each of the connecting shafts 12 away from each other, and four first bevel gears 15 meshing with each other, a straight gear 16 fixedly sleeved at the bottom end of each of the first rotating shafts 14, and a rack 18 fixedly installed on the inner side wall of each of the channel steel tracks 2 and meshing with the straight gears 16.

[0051] In this embodiment, the walking mechanism is significantly optimized, which improves the transmission efficiency and stability of the walking mechanism, enables the mounting box 3 to move along the track more quickly and accurately, and improves the working efficiency of the sound-absorbing cloth laying device, reduces the manufacturing cost, and improves the product quality. The core components of the mechanism include the double-shaft motor 11 fixedly installed in the mounting box 3, the connecting shaft 12 connected to each output shaft of the double-shaft motor 11 through a shaft coupling, the mounting plates 13 fixedly installed on each side of the mounting box 3, and the first rotating shafts 14 rotatably installed on the mounting plates 13. The distal ends of the rotating shafts and the connecting shaft 12 are provided with the first bevel gears 15, which mesh with each other to transmit power. Meanwhile, the straight gears 16 are fixedly sleeved at the bottom end of the first rotating shafts 14 and tightly mesh with the racks 18 on the inner side of the channel steel tracks 2 to drive the mounting box 3 to move linearly along the track. In addition, the mounting box 3 is provided with a plurality of walking wheels 17 on each side, which are in rolling connection with the channel steel tracks 2 to ensure smooth walking.

[0052] In this embodiment, the bottom plate 1 is fixedly provided with the vertical plate 5, and the vertical plate 5 is fixedly provided with the industrial camera 6 for monitoring the moving position and type of the automobile foam seat mold on the assembly line.

[0053] In this embodiment, the base plate 1 is firmly installed with the vertical plate 5, and one side of the vertical plate 5 is equipped with an advanced industrial camera 6. The main responsibility of this industrial camera 6 is to monitor the moving position and type of the automobile foaming seat mold on the production line in real time. By accurately capturing the position information and type data of the mold, the industrial camera 6 provides crucial information support for the entire laying device. The introduction of the industrial camera 6 greatly improves the intelligent level of the laying device. Through real-time monitoring and data analysis, the device can more accurately locate the mold position and adjust the laying strategy according to the mold type, so as to realize accurate and efficient laying of the sound-absorbing cloth. This not only improves production efficiency and reduces labor costs, but also ensures the consistency of product quality.

[0054] In further preferred embodiments of the present application, the lifting mechanism includes: two fixed grooves 21 symmetrically fixed on the top of the support plate 4, the grooves of the two fixed grooves 21 are opposite; two rodless cylinders 22 fixedly installed in the two fixed grooves 21 respectively, for providing lifting driving force; four stabilizing rods 23 fixedly installed in the two fixed grooves 21 respectively, the four stabilizing rods 23 are all vertically arranged; two support side plates 24 fixedly installed on the sliding seats of the two rodless cylinders 22 respectively, two sliding blocks 25 are fixedly installed on the side of each support side plate 24 away from each other, and the four sliding blocks 25 are respectively slidably sleeved on the four stabilizing rods 23.

[0055] In this embodiment, the design of the lifting mechanism fully demonstrates its innovation and practicality, achieving stable and precise lifting function. The lifting mechanism mainly includes two fixed grooves 21 symmetrically fixed on the top of the support plate 4, and the grooves of the two fixed grooves 21 are opposite, which provides a stable basis for subsequent lifting action. Each fixed groove 21 is provided with a rodless cylinder 22, which serves as the core power source of the lifting mechanism and can stably and accurately provide lifting driving force. In order to ensure the stability and smoothness of the lifting process, the mechanism also introduces four vertically arranged stabilizing rods 23.

The support side plates 24 are connected with the rodless cylinders 22 through the sliding seats of the cylinders, so as to realize synchronous lifting with the cylinders. At the same time, the cooperation of the sliding blocks 25 and the stabilizing rods 23 ensures the stability and perpendicularity of the support side plates 24 during lifting.

[0056] In a further preferred embodiment of the present application, the laying mechanism comprises a rotating mechanism, a direction adjusting mechanism, a distance adjusting mechanism and a negative pressure suction mechanism. The rotating mechanism comprises: a circular seat 31 fixedly installed on the top of the two support side plates 24, a circular groove being formed on the top of the circular seat 31; a circular block 32 arranged in the circular groove, a vertical pipe 33 fixedly installed on the top of the circular block 32; two sleeve plates 34 fixedly sleeved on the vertical pipe 33 for installing the direction adjusting mechanism; a middle shaft 35 fixedly installed on the bottom of the circular block 32, the middle shaft 35 and the vertical pipe 33 being arranged at the bottom center and the top center of the circular block 32, respectively; a mounting disc 36 fixedly installed on the bottom end of the middle shaft 35, an inner gear ring 37 fixedly installed on the bottom of the mounting disc 36; a machine base 38 fixedly installed between the two support side plates 24; a stepping motor 39 fixedly installed on the top of the machine base 38, a main gear 30 fixedly installed on the output shaft of the stepping motor 39, the main gear 30 being engaged with the inner gear ring 37.

[0057] In the present embodiment, the design of the laying mechanism fully considers the diversity and flexibility requirements in actual application. By integrating the rotating mechanism, the direction adjusting mechanism, the distance adjusting mechanism and the negative pressure suction mechanism, efficient and accurate laying of the sound-absorbing cloth is realized.

[0058] The rotating mechanism, as the core component of the laying mechanism, aims to realize switching and taking the sound-absorbing cloth in the tray at different positions. The circular seat 31 fixedly installed on the top of the two support side plates 24 provides stable support for the rotating mechanism. The circular block 32 in the circular groove cooperates with the circular seat 31, and through the connection of the middle shaft 35 and the vertical pipe 33, the smooth rotation is realized. The two sleeve plates 34 fixedly sleeved on the vertical pipe 33 provide convenience for the installation of the direction adjusting mechanism. The stepping motor 39, as the power source of the rotating mechanism, is engaged with the inner gear ring 37 on the bottom of the mounting disc 36 through the main gear 30 on the output shaft, realizing accurate control of the rotating mechanism. This design not only guarantees the stability and precision of rotation, but also enables the laying mechanism to be flexibly adjusted as needed. Through the rotating movement of the rotating mechanism, the negative pressure mechanism is used to suction the sound-absorbing cloth in the tray at different positions. The negative pressure suction mechanism is responsible for firmly suctioning the sound-absorbing cloth during the laying process to prevent it from falling off during movement.

[0059] In summary, the present application realizes accurate laying of the automobile foaming seat mold through the synergistic effect of the rotating mechanism, the direction adjusting mechanism, the distance adjusting mechanism and the negative pressure suction mechanism. This laying mechanism not only improves production efficiency and reduces labor cost, but also guarantees the consistency and stability of product quality. Therefore, the present application has wide application prospect and market value in the automobile seat manufacturing industry.

[0060] In the further preferred embodiment of the present application, the inner side wall of the circular groove on the circular seat 31 and the outer wall of the circular block 32 are both provided with a first annular groove, and a plurality of first rolling balls are arranged in the first annular groove. The bottom inner wall of the circular groove on the circular seat 31 and the bottom of the circular block 32 are both provided with a second annular groove, and a plurality of second rolling balls are arranged in the second annular groove.

[0061] In the present embodiment, the structural design between the circular seat 31 and the circular block 32 further enhances the performance of the rotating mechanism. In particular, the inner side wall of the circular groove on the circular seat 31 and the outer wall of the circular block 32 are both ingeniously provided with a first annular groove, and a plurality of first rolling balls are arranged in these grooves. Such design enables the first rolling balls to play a good lubricating and friction-reducing role when the circular block 32 rotates in the circular groove, thereby ensuring smoother and more stable rotation, reducing friction loss and noise. In addition, the bottom inner wall of the circular groove of the circular seat 31 and the bottom of the circular block 32 are also provided with a second annular groove, and a plurality of second rolling balls are arranged therein. These second rolling balls also provide effective lubrication and support when the circular block 32 rotates, further enhancing the stability and durability of the rotating mechanism.

[0062] In the further preferred embodiment of the present application, the negative pressure suction mechanism comprises a negative pressure pump 65 fixedly installed on the top of the machine base 38, and a multi-way pipe 66 fixedly connected to the air inlet end of the negative pressure pump 65. Four hoses 64 are respectively connected to the four ports of the multi-way pipe 66, and one end of each of the four hoses 64 is fixedly connected to an installation pipe 61. Four installation cylinders 62 are respectively fixedly installed on one end of the four installation pipes 61, and one end of each of the four installation cylinders 62 is open and fixedly installed with a suction disc 63 made of silica gel. The suction disc 63 is used to adsorb the sound-absorbing cloth when the installation cylinder 62 is in a negative pressure state due to the operation of the negative pressure pump 65.

[0063] In the present embodiment, the design of the negative pressure suction mechanism ingeniously combines the negative pressure pump 65, the multi-way pipe 66, the hose 64, the mounting pipe 61, the mounting cylinder 62, and the suction disc 63 made of silica gel, which work together to achieve efficient and stable adsorption of the sound-absorbing cloth. Specifically, the negative pressure pump 65 serves as the source of suction force, and the multi-way pipe 66 connected to its air inlet end evenly distributes negative pressure to the four hoses 64. This design not only ensures the uniformity of negative pressure but also improves the stability and reliability of adsorption. One end of the four hoses 64 is connected to the mounting pipe 61, allowing negative pressure to be smoothly conducted to the inside of the mounting cylinder 62. The suction disc 63 made of silica gel is fixedly installed at the open end of the mounting cylinder 62, has excellent sealing and flexibility, and can tightly adhere to the surface of the sound-absorbing cloth, thereby achieving firm adsorption of the sound-absorbing cloth. In actual application, when the negative pressure pump 65 is working, a negative pressure state is formed inside the mounting cylinder 62, and at this time the suction disc 63 will tightly adsorb the sound-absorbing cloth. This adsorption method is not only simple to operate but also has strong adsorption force, which can ensure that the sound-absorbing cloth does not easily fall off or shift during the laying process.

[0065] In the embodiment, the design of the orientation adjusting mechanism is ingenious and practical, which mainly comprises a U-shaped block 41, a second rotating shaft 43, a speed reducer motor 42 and a second bevel gear 44, etc., the U-shaped block 41 is fixedly installed at the same end of the two sleeve plates 34, so as to ensure the stability and reliability of the structure; the second rotating shaft 43 is arranged on the U-shaped block 41 in a rotating manner, so that the second rotating shaft 43 can be flexibly rotated when needed; the speed reducer motor 42 is fixedly installed on one side of the U-shaped block 41, and the output shaft thereof is fixedly sleeved with the second bevel gear 44 on the second rotating shaft 43, so that the speed reducer motor 42 can drive the second rotating shaft 43 to rotate, and the meshing of the two second bevel gears 44 ensures the smooth transmission of power and the accuracy of rotation, the introduction of the speed reducer motor 42 not only provides sufficient driving force, but also ensures the stability and accuracy of rotation through the speed reduction effect, so as to improve the performance of the entire orientation adjusting mechanism. In addition, the second rotating shaft 43 is also fixedly sleeved with a rectangular block 45, which is used to install the distance adjusting mechanism. Through the arrangement of the rectangular block 45, the installation and fixation of the distance adjusting mechanism are facilitated, and the close linkage between the orientation adjusting mechanism and the distance adjusting mechanism is formed.

[0066] In summary, the orientation adjusting mechanism of the present application drives the second rotating shaft 43 to rotate through the speed reducer motor 42, realizes the orientation adjustment of the distance adjusting mechanism installed thereon, and can meet the needs of different scenes for the laying position and direction of the soundproof cloth.

[0067] In further preferred embodiments of the present application, the laying device is also equipped with a controller to automatically control the operation of each electrical equipment, and the control circuit of the controller can be realized through simple programming by those skilled in the art. The power connection mode of each electrical equipment is a mature existing technology and is known to those skilled in the art, and therefore will not be described in detail.

[0068] In order to further improve the use effect of the device, in addition to the above-mentioned scheme, the present scheme also has the following embodiments:

[0069] In another embodiment of the present application, the distance adjusting mechanism comprises: two first push rod motors 51 fixedly installed on one side of the rectangular block 45, a connecting block 52 fixedly installed on the output rods of the two first push rod motors 51; two second push rod motors 53 fixedly installed on both sides of the connecting block 52, the two second push rod motors 53 being perpendicular to the two first push rod motors 51; first connecting plates 54 fixedly installed on the output rods of the two second push rod motors 53, two second connecting plates 55 fixedly installed on the first connecting plates 54; four third push rod motors 56 fixedly installed on one side of the four second connecting plates 55, the four third push rod motors 56 being symmetrically arranged in pairs and perpendicular to the two first push rod motors 51 and the two second push rod motors 53; mounting blocks 57 fixedly installed on the output rods of the four third push rod motors 56, and four mounting tubes 61 assembled on the mounting blocks 57.

[0070] In the present embodiment, the distance adjusting mechanism mainly comprises two first push rod motors 51, a connecting block 52, two second push rod motors 53, first connecting plates 54, second connecting plates 55, four third push rod motors 56, and mounting blocks 57. First, the two first push rod motors 51 are fixedly connected to the connecting block 52 through their output rods, so as to drive the connecting block 52 to move in the horizontal direction. This design enables the entire distance adjusting mechanism to accurately adjust the position of the sound-absorbing cloth in the horizontal direction. Second, two second push rod motors 53 are fixedly installed on both sides of the connecting block 52 and are perpendicular to the first push rod motors 51. Through the first connecting plates 54 and the second connecting plates 55 on the output rods of the two second push rod motors 53, the position adjustment in the direction perpendicular to the first push rod motors 51 is realized. This design further increases the flexibility of the distance adjusting mechanism, so that it can adapt to different laying requirements in different directions. In addition, the four third push rod motors 56 are symmetrically arranged in pairs and fixedly installed on one side of the second connecting plates 55. The output rods of the third push rod motors 56 are provided with mounting blocks 57, and four mounting tubes 61 are assembled on the four mounting blocks 57. This design enables the negative pressure adsorption mechanism not only to adjust the position in the horizontal plane, but also to adjust the height in the vertical direction, so as to realize the accurate laying of the sound-absorbing cloth in the three-dimensional space.

[0071] In summary, the distance adjusting mechanism of the present application realizes the accurate position adjustment of the four suction cups 63 through the cooperative work of multiple push rod motors, so that they correspond to the positions of the four hanging nails on the mold. This design not only improves the laying accuracy and efficiency, but also makes the entire laying mechanism more flexible and easy to use.

[0072] In still another embodiment of the present application, sliding holes are formed in the four mounting blocks 57, four mounting pipes 61 respectively pass through the four sliding holes and are respectively in sliding connection with the four mounting blocks 57, and first triggering mechanisms are arranged on the four mounting blocks 57, the first triggering mechanism comprises: a limiting ring block 71 fixedly sleeved on the mounting pipe 61, the limiting ring block 71 is located on the side of the mounting block 57 away from the mounting cylinder 62; a sliding ring block 72 slidably sleeved on the mounting pipe 61, the sliding ring block 72 is located between the mounting block 57 and the mounting cylinder 62; a first spring 73 slidably sleeved on the mounting pipe 61, the first spring 73 is located between the sliding ring block 72 and the mounting cylinder 62; and a first sheet type pressure sensor 74 fixedly installed on the side of the mounting block 57, the first sheet type pressure sensor 74 is located between the mounting block 57 and the sliding ring block 72.

[0073] In the embodiment, in order to further improve the stability and automation degree of adsorption, the first triggering mechanism is arranged on the mounting block 57. The first triggering mechanism comprises the limiting ring block 71 fixedly sleeved on the mounting pipe 61, the sliding ring block 72 slidably sleeved on the mounting pipe 61 and the first spring 73. When the suction cup 63 adsorbs the sound-absorbing cloth, the sliding ring block 72 moves to the mounting block 57 under the pressure, thereby triggering the first sheet type pressure sensor 74. The triggering signal makes the controller automatically start the negative pressure pump 65, so that the sound-absorbing cloth is adsorbed by the suction cup 63. Therefore, the automation degree of adsorbing the sound-absorbing cloth of the device is greatly improved, and the production efficiency is greatly improved.

[0074] In still another embodiment of the present application, second triggering mechanisms are further arranged in the four mounting cylinders 62, the second triggering mechanism comprises: two fixed sliding rods 75 fixedly installed on the inner wall of the mounting cylinder 62, the ends of the two fixed sliding rods 75 away from the mounting pipe 61 are fixedly installed with limiting blocks; a fixed block 76 fixedly sleeved on the two fixed sliding rods 75; a pressing plate 77 slidably sleeved on the two fixed sliding rods 75, the pressing plate 77 is located between the fixed block 76 and the limiting block; two second springs 78 respectively slidably sleeved on the two fixed sliding rods 75, the two second springs 78 are located between the fixed block 76 and the pressing plate 77; and a second sheet type pressure sensor 79 fixedly installed on the side of the fixed block 76 close to the pressing plate 77.

[0075] In the embodiment, the negative pressure adsorption mechanism is further improved and optimized, especially the second triggering mechanism is additionally arranged in the mounting cylinder 62. The innovative design not only enhances the stability and safety of the mechanism, but also improves the real-time monitoring capability of the adsorption state.

[0076] Specifically, the second trigger mechanism mainly consists of two fixed slide rods 75, a fixed block 76, a pressing plate 77, two second springs 78 and a second sheet pressure sensor 79. The cooperative work of these components enables the installation cylinder 62 to sense the pressure change in real time when the sound-absorbing cloth is attached, thereby realizing accurate monitoring of the attachment state.

[0077] The fixed slide rod 75 is firmly installed on the inner wall of the installation cylinder 62 as a support structure of the entire trigger mechanism. The fixed block 76 is sleeved on the fixed slide rod 75, providing a stable mounting position for the second spring 78 and the pressing plate 77. The pressing plate 77 can slide on the fixed slide rod 75 and move towards the fixed block 76 when subjected to pressure. The second spring 78 is located between the fixed block 76 and the pressing plate 77, serving as a buffer and reset.

[0078] When the sound-absorbing cloth attached by the suction cup 63 is hung on the nails of the mold, the nails pierce the sound-absorbing cloth and block the pressing plate 77, and the fixed block 76 continues to move as the output rod of the first push rod motor 51 continues to lengthen, until the second sheet pressure sensor 79 on the fixed block 76 contacts and presses the pressing plate 77, and the second sheet pressure sensor 79 is pressed by the pressing plate 77 to reach the set pressure value, thereby automatically controlling the negative pressure pump 65 to stop running through the controller, so that the suction cup 63 loses the attachment to the sound-absorbing cloth, and at the same time, the two first push rod motors 51 are automatically controlled to start, so that the output rod is shortened, and the suction cup 63 moves away from the nails to restore the initial state. The setting of the second trigger mechanism realizes the automatic stop of the negative pressure pump 65, greatly improving the automation degree of the device.

[0079] It is worth noting that the circuits, electronic components and modules involved in the present application are all prior art and can be implemented by those skilled in the art without further description. The content protected by the present application does not involve improvement of software and methods.

[0080] The present application also proposes a sound-absorbing cloth laying method for a car seat foaming mold, which comprises:

[0081] First, stack the sound-absorbing cloth in each tray beside the production line. The car seat foaming mold on the production line moves over, and the industrial camera 6 monitors the shape of the car seat foaming mold and the position of the four nails on the mold;

[0082] The controller automatically controls the reduction motor 42 in the adjustment mechanism to start, drives the second shaft 43 to rotate, thereby driving the rectangular block 45 to rotate, and thereby driving the four suction cups 63 towards the sound-absorbing cloth in the tray beside the production line through the distance adjustment mechanism;

[0083] Then, the two first push rod motors 51 are automatically started synchronously, the output rods are elongated, the four suction cups 63 are lowered, and the uppermost layer of the sound-absorbing cloth in the tray is pressed. The output rods of the first push rod motors 51 continue to be elongated, the mounting blocks 57 continue to be lowered, the first springs 73 are compressed, the sliding ring blocks 72 press the first sheet type pressure sensors 74, and when the pressure reaches the set pressure value, the negative pressure pump 65 is automatically started through the controller, so that the four mounting barrels 62 are in a negative pressure state, so that the suction cups 63 adsorb the uppermost layer of the sound-absorbing cloth;

[0084] Then, the output rods of the first push rod motors 51 are shortened, the sound-absorbing cloth is adsorbed by the suction cups 63, and as the suction cups 63 rise, the reduction motor 42 is automatically started and reversed, the rectangular block 45 is driven to rotate through the second rotating shaft 43, so that the four suction cups 63 are turned to the direction of the mold, and the output rods of the two second push rod motors 53 and the four fourth push rod motors are shortened, the distance between the four suction cups 63 is adjusted, and the position corresponds to the position of the four hooks on the mold;

[0085] Then, the two rodless cylinders 22 are started, driving the two support side plates 24 to move vertically, and the two sliding blocks 25 slide along the two stabilizing rods 23 to adjust the height of the laying mechanism, so that the height position of the four suction cups 63 corresponds to the position of the four hooks on the mold;

[0086] At the same time, the controller automatically starts the double-shaft motor 11 to drive the two connecting shafts 12 to rotate, and the two first rotating shafts 14 are driven to rotate through the four first bevel gears 15, so that the two straight gears 16 are driven to rotate. Since the two straight gears 16 are engaged with the two racks 18, the two straight gears 16 move along the racks 18 while rotating, so that the mounting box 3 moves. At the same time, the walking wheels 17 on both sides of the mounting box 3 roll on the inner wall of the channel steel track 2. The movement of the mounting box 3 makes the laying mechanism move synchronously and at the same speed as the mold on the production line;

[0087] At the same time, the output rods of the first push rod motors 51 are elongated, so that the four suction cups 63 and the sound-absorbing cloth adsorbed thereby move towards the hooks until the sound-absorbing cloth is pierced by the four hooks, and the hooks hinder the continuous movement of the pressing plate 77 in the suction cup 63. The fixed block 76 continues to move as the output rod of the first push rod motor 51 continues to elongate, until the second sheet type pressure sensor 79 on the fixed block 76 contacts and presses the pressing plate 77, and the second sheet type pressure sensor 79 is pressed by the pressing plate 77. When the pressure reaches the set value, the negative pressure pump 65 is automatically controlled to stop running through the controller, so that the suction cup 63 loses the adsorption of the sound-absorbing cloth, and at the same time, the two first push rod motors 51 are automatically controlled to start, so that the output rods are shortened, the suction cups 63 move away from the hooks, and the initial state is restored;

[0088] Then, the double-shaft motor 11 is automatically started to reverse, so that the installation box 3 moves reversely, and the device returns to the initial state;

[0089] When the industrial camera 6 monitors the type of the automobile seat foaming mold, and the matched sound-absorbing cloth is placed in the tray on the table, the stepper motor 39 is started to drive the main gear 30 to rotate, so as to drive the inner tooth ring 37 to rotate, and then drive the middle shaft 35 to rotate through the installation disc 36, the middle shaft 35 drives the vertical pipe 33 to rotate through the circular block 32, so as to drive the two sleeve plates 34 to rotate half a circle, and the suction cup 63 is rotated to the upper side of the tray on the table, then the sound-absorbing cloth can be adsorbed according to the above-mentioned mode, and then the stepper motor 39 is reversed to drive the suction cup 63 adsorbing the sound-absorbing cloth to face the mold, then the sound-absorbing cloth on the suction cup 63 can be hung on the nails according to the above-mentioned mode, and the initial state is restored.

[0090] In summary, compared with the related art, the automobile seat foaming mold sound-absorbing cloth laying device and laying method proposed by the present application realizes efficient, accurate and automatic laying of sound-absorbing cloth as a whole. By accurately controlling each mechanism and device, the present application not only improves production efficiency and reduces labor cost, but also significantly reduces operation error and improves product quality. In addition, the design of the device is flexible and variable, and can adapt to different types and specifications of molds and sound-absorbing cloths, and has wide applicability and practicality. In general, the present application brings significant benefits and improvement to the automobile seat manufacturing industry.
