Description

Technical Field

[0001] This invention relates to the field of automotive front carpet processing technology, and more specifically, to an automatic pressing machine for automotive front carpet footrest spring cards. Background Technology

[0002] Car carpets are essential interior trim components for automobiles, primarily used to cover the metal parts at the bottom of the car's interior cavity and some important components. The front end of the car carpet serves as a footrest, and several connecting posts are located on the side of the footrest closest to the car body. Corresponding spring clips need to be pressed into the outer wall of these connecting posts.

[0003] In existing technologies, the assembly of the aforementioned spring clips typically employs a manual pressing method. This involves workers manually grasping the spring clips and pressing them one by one into the outside of the connecting column, ensuring they abut against the outer surface of the footplate. This assembly method is not only time-consuming and labor-intensive, resulting in high labor intensity and low work efficiency, but manual pressing is also prone to defects such as omissions or incomplete pressing, leading to a low product quality pass rate. Summary of the Invention

[0004] The problem solved by this invention is to overcome at least one defect in the prior art and provide an automatic pressing machine for spring cards of automotive front carpet footrests, which realizes automatic material picking and pressing of spring cards without manual intervention, reduces the labor intensity of workers, improves work efficiency, and reduces the likelihood of missing cards.

[0005] To solve the above problems, the present invention provides an automatic pressing machine for automotive front carpet footrest spring clips, comprising:

[0006] The frame is a rectangular and hollow frame structure;

[0007] A positioning mechanism, mounted on the base plate of the frame, is used to place and position the front carpet of the vehicle;

[0008] The pressing mechanism includes a fixed plate and a pressing drive cylinder for driving its lifting and connecting to the top plate of the frame. The lower end of the fixed plate is connected to multiple pressing rods. Each pressing rod corresponds to the position of the spring card to be pressed on the front carpet of the car and forms a pressing station. The lower end of each pressing rod is provided with a positioning groove for accommodating and positioning the spring card.

[0009] The feeding mechanism includes multiple storage sleeves set on the rear side plate of the inner cavity of the frame. A mounting plate is set below the storage sleeves, and a pushing component is set on the mounting plate for pushing the spring card at the bottom of each storage sleeve to move horizontally.

[0010] The material transfer mechanism includes a material transfer plate, a material transfer drive assembly, and a material ejector assembly. The material transfer drive assembly is connected to the frame, the material transfer plate is connected to the drive end of the material transfer drive assembly, and the material ejector assembly is connected to the lower end of the material transfer plate. When the material transfer drive assembly drives the material transfer plate to the loading station near the storage sleeve, the material pusher assembly is used to push the lowest spring card in each storage sleeve onto the material transfer plate. When the material transfer plate carrying the spring cards is transferred to the pressing station, the material ejector assembly is used to push each spring card upward into its corresponding positioning slot.

[0011] The automatic pressing machine for automotive front carpet footrest spring clips of the present invention has the following advantages compared with the prior art:

[0012] The automatic pressing machine for spring cards on automotive front carpet footrests of the present invention is a dedicated assembly fixture, including a dedicated operating frame with corresponding working chambers. A positioning mechanism for clamping and positioning the automotive front carpet is provided on the bottom plate of the working chamber, and an automatic pressing mechanism is provided above it. Additionally, a storage sleeve is provided on the rear side wall of the working chamber for temporarily storing the spring cards to be pressed. During assembly, each storage sleeve is ensured to be full of spring cards, and the automotive front carpet is positioned on the corresponding positioning mechanism, ensuring the spring card pressing position is horizontally upward. A material transfer drive assembly drives a material transfer plate to reciprocate. When it moves to the loading position near the mounting plate, a pushing assembly pushes the lowest spring card from each storage sleeve onto the material transfer plate. On the material plate, the transfer drive assembly moves the transfer plate carrying the spring cards to the pressing station. Then, the ejector assembly pushes each spring card upward into its corresponding positioning slot. The transfer plate then reverses and moves back to the loading station. Finally, the pressing drive cylinder operates to drive the fixing plate and multiple pressure rods downward. When the pressure rods reach the set position, the spring cards in each positioning slot are pressed into the footrest position of the car front carpet. The car front carpet is then removed and replaced with a new one. The transfer mechanism operates again, achieving continuous automated assembly. During the assembly process, the picking of spring cards and the final pressing do not require manual intervention, reducing labor intensity and improving work efficiency. Furthermore, the use of dedicated pressure rods for pressing ensures that the spring cards are pressed flat and accurately positioned.

[0013] As an improvement, a liftable positioning plate is provided below the mounting plate. Multiple vertically positioned rods are connected to the positioning plate, and the upper ends of each positioning rod can extend into a corresponding storage sleeve to guide and limit the placement of spring cards into the storage sleeve. In this improved structure, when the spring cards in each storage sleeve are used up and new materials need to be prepared, the guiding action of the positioning rods ensures that the spring cards fall smoothly and stack into the storage sleeve without tilting or jamming.

[0014] In a further improvement, the lower end of the mounting plate is connected to a vertically positioned rodless cylinder, and the positioning plate is horizontally connected to the slider of the rodless cylinder. The lower end face of the mounting plate is provided with multiple guide tubes corresponding to each storage sleeve, and each guide tube has a connecting hole at its center for the positioning rod to pass through. The upper ends of each positioning rod are slidably fitted into their respective guide tubes. In this improved structure, the positioning rods are driven up and down by the rodless cylinder, resulting in a simple structure and stable drive. Furthermore, the guide tubes ensure that the guide rods can smoothly enter the storage sleeves without easily deviating.

[0015] In a further improvement, a fixing block is provided on the mounting plate, and each of the storage sleeves is vertically mounted on the fixing block. A feeding channel, large enough for only a single spring card to pass through, is provided between the lower end face of each storage sleeve and the upper end face of the mounting plate. In this improved structure, the feeding channel of appropriate height ensures that one spring card is pushed out at a time, improving work efficiency.

[0016] Furthermore, the pushing assembly includes a pushing plate and a pushing drive cylinder that drives the pushing plate to move horizontally, with one end of the pushing plate away from the pushing drive cylinder able to pass through the feeding channel. In the above improved structure, the pushing plate enables multiple bottom-level spring cards to be smoothly pushed simultaneously in the horizontal direction, improving work efficiency.

[0017] In a further improvement, each of the storage sleeves has a monitoring through-hole on its lower sidewall, and the outer wall of the fixing block is equipped with multiple sensors, each sensor corresponding to a monitoring through-hole. In this improved structure, the sensors and monitoring through-holes facilitate monitoring of whether there are still spring clips inside the storage sleeve, preventing situations where spring clips are used up but assembly continues, leading to missed installations.

[0018] Furthermore, the material transfer drive assembly includes a vertically arranged connecting shaft. The lower end of the connecting shaft is connected to one end of the material transfer plate, and the upper end of the connecting shaft extends through the top plate of the frame. A gear is connected to the end of the connecting shaft extending through the top plate. A rack and a material transfer drive cylinder for driving the rack to move horizontally are provided on the upper end of the top plate, and the rack meshes with the gear. In the above improved structure, the rotation of the connecting shaft is achieved by driving the rack and gear, which in turn drives the horizontal rotation of the material transfer plate, realizing the position transfer of the spring card, resulting in smooth and convenient driving.

[0019] In a further improvement, a first guide rail is provided on the top plate of the frame, and a second guide rail extending along its length is provided on the outer wall of the other end of the transfer plate. A linkage rod parallel to the connecting shaft is provided between the first and second guide rails, and the upper and lower ends of the linkage rod are slidably engaged with the first and second guide rails via a first slider and a second slider, respectively. In the above improved structure, the two sets of linear guide rail structures effectively ensure the stability of the transfer plate during rotation.

[0020] In a further improvement, a bearing seat is provided on the inner side wall of the frame, and a bearing is installed in the bearing seat. The lower end of the connecting shaft passes through the inner hole of the bearing. In the above improved structure, the lower end of the connecting shaft is connected to the frame through a bearing, ensuring the flexibility and stability of the connecting shaft's rotation.

[0021] Furthermore, the ejector assembly includes multiple ejector cylinders disposed on the lower end face of the transfer plate. Each ejector cylinder has an ejector block connected to its piston rod. The transfer plate has clearance holes corresponding to each ejector cylinder, and each ejector block slides within its corresponding clearance hole. In this improved structure, the ejector cylinders and ejector blocks work together to transfer the spring clips from the transfer plate to the positioning groove at the lower end of the pressure rod, achieving rapid and efficient transfer while ensuring that each spring clip maintains an accurate angle within the positioning groove.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] In the description of this invention, it should be noted that the terms "above," "upper surface," "lower end," and "rear side," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, in the description of this invention, the terms "first," "second," and "third" are used only for the convenience of description and distinction, and do not have any specific meaning.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] like Figures 1-6As shown, this invention provides an automatic pressing machine for spring clips on automotive front carpet footrests, including a frame 1. The frame 1 is a rectangular and hollow frame structure, comprising a top plate, a bottom plate, left and right side plates, and a rear side plate, with an opening on its front side forming an operating window. A positioning mechanism 2 for placing and positioning the automotive front carpet is provided on the bottom plate of the frame 1. This mechanism includes a support frame spaced at different heights, and positioning blocks are provided on the top of both support frames. When positioning the automotive front carpet, one end of the footrest is placed on the higher positioning block, and the other end is placed on the lower positioning block, facilitating the horizontal positioning of the footrest where the spring clips need to be installed.

[0035] Additionally, a pressing mechanism is provided on the top plate of the frame 1, which includes a horizontally arranged fixed plate 3 and a pressing drive cylinder 4 for driving its lifting and lowering. The pressing drive cylinder 4 is connected to the top plate of the frame 1. The lower end of the fixed plate 3 is connected to multiple pressing rods 5. Each pressing rod 5 corresponds to the position of the spring card to be pressed on the front carpet of the car and forms a pressing station. The lower end of each pressing rod 5 is provided with a positioning groove for accommodating and positioning the spring card. When the spring card is installed in the accommodating groove of each pressing rod 5, the pressing drive cylinder 4 drives the fixed plate 3 to move downward, and simultaneously drives the multiple pressing rods 5 to move downward. When it moves to the set position, the spring card in each positioning groove is pressed into the footrest position of the front carpet of the car.

[0036] In this embodiment, as Figure 4 As shown, a vertically arranged third guide rail 33 is installed on the side column of the frame 1. A third slider 34, which slides and engages with the third guide rail 33, is connected to the outer wall of the fixed plate 3. This ensures that the fixed plate 3 can move vertically and smoothly downwards when pressing the spring clips, thereby ensuring that the spring clips positioned at the lower end of each pressure rod 5 can be pressed accurately into the footrest position of the car's front carpet. Furthermore, to ensure that the piston rod of the pressing drive cylinder 4 does not easily deviate during extension and retraction, two guide rods 39 are connected to the upper end face of the fixed plate 3. Two guide sleeves 40 are correspondingly connected to the top plate of the frame 1, and the upper ends of the two guide rods 39 slide and engage within the two guide sleeves 40 respectively.

[0037] More specifically, such as Figure 3As shown, in this embodiment, in order to ensure that the fixing plate 3 will not fall due to the loss of control of the pressing drive cylinder 4 when it is not in the pressing state, a positioning insert plate 35 is connected to the upper end face of the fixing plate 3, and a positioning insertion hole 36 is provided at the upper end of the positioning insert plate 35. A through hole for the positioning insert plate 35 to pass through is provided on the top plate of the frame 1, and a horizontally placed locking pin drive cylinder 37 is provided on the upper end face of the top plate. A positioning locking pin 38 is connected to the piston rod of the locking pin drive cylinder 37. When the fixing plate 3 is in the initial position, the upper end of the positioning insert plate 35 protrudes from the top plate. The locking pin drive cylinder 37 is used to drive the positioning locking pin 38 to be inserted and limited in the positioning insertion hole 36, so as to prevent the fixing plate 3 from falling accidentally and ensure safety.

[0038] like Figure 1 , 3 As shown, multiple storage sleeves 6 are provided on the rear side wall of the inner cavity of the frame 1, and an installation plate 7 is provided on the side wall below the storage sleeves 6. The installation plate 7 is provided with a pusher assembly for pushing the bottommost spring card of each storage sleeve 6 to move horizontally. In this embodiment, a crossbeam 41 is connected to the rear side wall of the inner cavity of the frame 1, and the installation plate 7 is fixed on the crossbeam 41.

[0039] like Figure 3 , 4 As shown in Figure 6, the automatic pressing equipment in this embodiment also includes a material transfer mechanism, specifically including a material transfer plate 8, a material transfer drive assembly, and a material ejector assembly. The material transfer drive assembly is connected to the frame 1, the material transfer plate 8 is connected to the drive end of the material transfer drive assembly, and the material ejector assembly is connected to the lower end of the material transfer plate 8. When the material transfer drive assembly drives the material transfer plate 8 to the loading station near the mounting plate 7, the material pusher assembly is used to push the lowest spring card in each storage sleeve 6 onto the material transfer plate 8. Then, the material transfer drive assembly transfers the material transfer plate 8 carrying the spring cards to the pressing station. At this time, the material transfer plate 8 is located directly below each pressure rod 5, and the multiple spring cards on the material transfer plate 8 are respectively connected to the lower end of each pressure rod 5. The positioning slots at each end correspond one-to-one. Then, the top material assembly pushes each spring card upward until each spring card is engaged in its corresponding positioning slot. Then, the transfer plate 8 reverses and moves to the loading station. Finally, the pressing drive cylinder 4 operates to drive the fixing plate 3 to move multiple pressure rods 5 downward. When the pressure rods 5 move to the set position, the spring cards in each positioning slot are pressed onto the connecting post at the footrest position of the car front carpet. Then, the car front carpet is removed and replaced with a new car front carpet. The transfer mechanism operates again to achieve continuous automated assembly. During the assembly process, the picking of spring cards and the final pressing do not require manual intervention, reducing labor intensity and improving work efficiency.

[0040] In the above structure, to improve the level of automation, when the spring cards in each storage sleeve 6 are used up and materials are refilled, it is ensured that the spring cards fall smoothly into the storage sleeve 6 without jamming. In this embodiment, for example... Figure 4 As shown, a liftable positioning plate 9 is provided below the mounting plate 7. Multiple vertically positioned positioning rods 10 are connected to the positioning plate 9. The upper end of each positioning rod 10 can extend into its corresponding storage sleeve 6 to guide and limit the placement of spring clips into the storage sleeve 6. More specifically, a vertically positioned rodless cylinder 11 is connected to the lower end of the mounting plate 7, and the positioning plate 9 is horizontally connected to the slider of the rodless cylinder 11. Furthermore, multiple guide tubes 12, corresponding one-to-one with each storage sleeve 6, are provided on the lower end face of the mounting plate 7. A connecting hole for the positioning rod 10 to pass through is provided at the center of each guide tube 12. The upper end of each positioning rod 10 slides within its corresponding guide tube 12. When the spring cards in each storage sleeve 6 are used up and need to be refilled, the rodless cylinder 11 operates, driving the positioning plate 9 and multiple positioning rods 10 to move upward until the upper end of each positioning rod 10 passes through the corresponding connecting hole and extends into the storage sleeve 6. The upper end surface of each positioning rod 10 after moving upward is almost flush with the upper end surface of each storage sleeve 6, and each positioning rod 10 is located in the center position in each storage sleeve 6. This allows the spring card to pass through the middle hole of the positioning rod 10 when it is put into the storage sleeve 6, and slide down along the positioning rod 10. The guiding action of the positioning rod 10 ensures that the spring card falls smoothly and stacks into the storage sleeve 6. After the material preparation is completed, the rodless cylinder 11 moves downward to reset, waiting for the next material preparation.

[0041] In this embodiment, in order to ensure that all storage sleeves 6 are connected and fixed at the same height, a fixing block 13 is provided on the mounting plate 7, such as... Figure 3 , 7 As shown; specifically, the two ends of the fixing block 13 are respectively mounted on the mounting plate 7 through the support block, and there is a gap between the fixing block 13 and the mounting plate 7. Each storage sleeve 6 is vertically mounted on the fixing block 13. Specifically, the lower end of each storage sleeve 6 passes through the fixing block 13, and there is a feeding channel 14 between the lower end face of each storage sleeve 6 and the upper end face of the mounting plate 7, which can only allow a single spring card to pass through.

[0042] Other, such as Figure 3 , 7As shown, the pushing assembly includes a pushing plate 15 and a pushing drive cylinder 16 that drives the pushing plate 15 to move horizontally. One end of the pushing plate 15 away from the pushing drive cylinder 16 can pass through the feeding channel 14 to horizontally push the lowest spring card in each storage sleeve 6. Specifically, one end of the ejector plate is connected to the piston rod of the pushing drive cylinder 16, and the other end of the ejector plate is slidably fitted in the feeding channel 14. Furthermore, the portion of the pushing plate 15 located in the feeding channel 14 has multiple discharge holes 32 corresponding to the inner holes of each storage sleeve 6. The bottommost spring card in the storage sleeve 6 is located inside the drop hole 32. This ensures that when the pusher plate 15 moves forward, the bottommost spring card in each storage sleeve 6 is pushed out horizontally at the same time. After the pusher plate 15 is reversed and reset, the spring cards in each storage sleeve 6 continue to move downward. The spring card that was originally located in the second to last layer at the bottom falls into the drop hole 32 and becomes the bottommost spring card. By the reciprocating movement of the pusher plate 15, the spring cards in the storage sleeve 6 can be pushed out one by one, ensuring that only one card can be pushed out at a time.

[0043] In this structure, to facilitate monitoring of whether there are still spring clips inside the storage sleeve 6, monitoring through holes 17 are provided on the side wall at the lower end of each storage sleeve 6. Multiple sensors 18 are installed on the outer wall of the fixing block 13, and each sensor 18 corresponds to a monitoring through hole 17. The sensors 18 are used to monitor the remaining spring clips in the storage sleeve 6 in real time. Figure 7 As shown; when sensor 18 does not detect any spring cards, it indicates that the remaining spring cards are less than the set value, reminding the operator to replenish the material in the storage kit in time.

[0044] In this embodiment, as Figure 4 , 6 As shown, the material transfer drive assembly includes a vertically arranged connecting shaft 19. The lower end of the connecting shaft 19 is connected to one end of the material transfer plate 8, and the upper end of the connecting shaft 19 extends through the top plate of the frame 1. A gear 20 is connected to the end of the connecting shaft 19 extending through the top plate. A rack 21 and a material transfer drive cylinder 22 for driving the rack 21 to move horizontally are provided at the upper end of the top plate. The rack 21 meshes with the gear 20. The extension and retraction of the material transfer drive cylinder 22 drives the rack 21 to move horizontally, thereby driving the connecting shaft 19 to rotate circumferentially, driving the material transfer plate 8 to rotate horizontally, thus moving the spring card from the loading station to the pressing station. The structure is simple and the drive is stable.

[0045] Other, such as Figure 2As shown, to ensure the stability of the transfer plate 8 during rotation, a first guide rail 23 is provided on the top plate of the frame 1, and a second guide rail 24 extending along its length is provided on the outer wall of the other end of the transfer plate 8. A linkage rod 25 parallel to the connecting shaft 19 is provided between the first guide rail 23 and the second guide rail 24, and the upper and lower ends of the linkage rod 25 are slidably engaged with the first guide rail 23 and the second guide rail 24 through a first slider 26 and a second slider 27, respectively. Figure 2 , 4 As shown in Figure 6, the first guide rail 23 is inclined to the front wall of the frame 1, and its two ends are directly connected to the positions on the top plate of the frame 1 corresponding to the loading station and the pressing station. During the process of the connecting shaft 19 rotating to drive the transfer plate 8 to move from the loading station to the pressing station, the first slider 26 at the upper end of the linkage rod 25 slides towards the pressing station, and the second slider 27 slides towards one end of the connecting shaft 19. Through the limiting of the two sets of linear guide rail structures, the stability of the transfer plate 8 during rotation is effectively guaranteed, thereby ensuring that the spring card will not fall off during the transfer process and avoiding the situation of missing installation. Furthermore, in the above structure, a bearing seat 28 is also provided on the inner wall of the frame 1. A bearing is installed in the bearing seat 28, and the lower end of the connecting shaft 19 passes through the inner hole of the bearing, ensuring the flexibility and stability of the rotation of the connecting shaft 19.

[0046] like Figure 5 , 6 As shown, the top material assembly includes multiple top material cylinders 29 disposed on the lower end face of the transfer plate 8. Each top material cylinder 29 has a top material block 30 connected to its piston rod. Each position on the transfer plate 8 corresponding to each top material cylinder 29 has a clearance through hole 31. Each top material block 30 is slidably fitted into the corresponding clearance through hole 31. When the transfer plate 8 with spring clips is moved to the pressing station by the transfer drive cylinder 22, each spring clip on the transfer plate 8 is located directly below each pressure rod 5 and aligned with the positioning groove at the bottom of each pressure rod 5. Then, each ejector cylinder 29 is activated, and each ejector block 30 pushes out the spring clips directly above the clearance through hole 31 into the corresponding positioning groove. After ejection, the transfer plate 8 is reversed and rotated. At this time, there is only the pressure rod 5 structure directly above the position where the spring clips need to be installed on the front carpet footrest of the car, without any other parts interfering. Finally, the pressing drive cylinder 4 is activated, driving the fixing plate 3 to move the multiple pressure rods 5 vertically downward until the spring clips at the lower end of each pressure rod 5 are pressed and fitted onto the front carpet footrest of the car, completing the entire pressing process.

[0047] More specifically, in this embodiment, a corresponding visual inspection component (not shown in the figure) can be set on the frame 1 to detect whether the spring card is missing. A corresponding display screen is installed on the outer wall of the frame 1. The visual inspection component can transmit the captured image to the display screen in real time and compare it with the preset qualified image in the display screen to determine whether there is a missing card.

[0048] Additionally, the drive cylinder described above can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0049] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
