Description

Technical Field

[0001] The invention relates to the technical field of rubber strip installation, in particular to a vehicle door rubber strip installation device. Background Art

[0002] During the installation of the rubber strips of the door panels, the traditional installation method is manual assembly, but due to the low assembly efficiency, the production efficiency of the entire production line is affected, and the installation accuracy is not high enough.

[0003] For this reason, some mechanical installation processes have emerged to achieve automated operation of the rubber strips. This installation method is to press the rubber strips into the grooves by squeezing them when they are delivered to the grooves of the door panels. However, this method can only be used to install rubber strips for grooves that are small inside and large outside, and cannot be used for grooves that are large inside and small outside or of different shapes; and after the installation is completed and the squeezing force is removed, some of the rubber strips will retreat outward.

[0004] Based on this, our company has designed a new process that is very different from ordinary installation, allowing the rubber strip to be installed by insertion, which can effectively solve the above problems.

[0005] In order to realize insertion and ensure the accuracy of position and the smoothness of operation, the platform, feeding mechanism and traction mechanism are designed. Summary of the invention

[0034] The present invention has the following advantages:

[0035] (1) This solution realizes a new way of inserting and installing the rubber strip in the groove of the door panel by designing a platform, a feeding mechanism, and a traction mechanism, and has a high degree of automation; the design of the platform enables the door panel to automatically adjust its position, and even if it is placed randomly, it can automatically adjust to the appropriate position, thereby improving work efficiency; the feeding mechanism ensures the fullness of the rubber strip, and the rubber strip is deformed during installation; the traction mechanism has high positioning accuracy, stable operation, and high installation accuracy, which ensures smooth insertion;

[0036] (2) The positioning reference block, positioning cylinder, rear adjustment cylinder and right adjustment cylinder are set. The left and front sides of the door panel are positioned by the positioning reference block and positioning cylinder. When the rear adjustment cylinder and right adjustment cylinder extend, they respectively abut against the rear and right sides of the door panel, thereby gradually correcting the position of the door panel and achieving positioning.

[0037] (3) The calibration cylinder is used to calibrate the positioning reference block; the front roller support is provided to support the door handle and to calibrate the positioning cylinder; the design of the reference table and the long table ensures the accurate position of the track and the accurate position between the track and the door panel, which is conducive to accurate installation;

[0038] (4) By setting up a height adjustment mechanism and an angle adjustment mechanism, the rubber strip can be adaptively adjusted according to the model of the rubber strip; and when adjusting the height, only the strip plate needs to be adjusted to adjust the upper guide wheel and the driven traction wheel together, and the two can act together, which is convenient; by setting up an external support structure and an internal support structure, the fullness of the rubber strip during installation is ensured, and deformation will not occur, resulting in a situation where the rubber strip cannot be installed, and smooth installation can be achieved;

[0039] (5) The setting of the tightening mechanism and the pressing mechanism is not only to make the rubber strip stick to the rigid core, but also to clamp the left end of the rubber strip to form a front-to-back limit when the left end of the rubber strip is separated from the bracket slot. This prevents the rubber strip from deforming in the front-to-back direction, so that the tail end of the rubber strip can be smoothly inserted into the door panel slot. The setting of the pressing cam, the rotating shaft and the self-locking steering motor can adjust the pressing force by rotating the pressing cam according to the actual situation, which is convenient for adjustment.

[0040] (6) Through the groove rail, spur rail, meshing position of the gear and spur rail, and the inverted "J" part of the bent plate are located in the same horizontal plane, so that the slide can produce a good force effect in the horizontal direction; and this setting reduces the slide's tipping tendency, which is conducive to the smooth sliding of the slide;

[0041] (7) The structure of the displacement block, displacement base plate, and the structure between the rectangular table and the I-shaped piece ensure the position accuracy and stability of the finger clamping cylinder. During insertion, there will be no interference between the finger head and the door panel, thus achieving precise insertion;

[0042] (8) The structure of the spacing formed by the rectangular table and the I-shaped member, as well as the setting of the guide light axis, make it possible to accurately adjust the height of the finger clamping cylinder, so that the fingers on the upper and lower sides can clamp the rubber strip with the same force from the upper and lower sides to avoid deformation of the rubber strip; and the setting of the I-shaped member and the guide light axis can realize automatic adaptation and adjustment of the height when the I-shaped member clamps the rubber strip.

DETAILED DESCRIPTION

[0060] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0061] like Figure 1 to Figure 14 As shown, the vehicle door rubber strip installation device includes a platform 1000, a feeding mechanism 2000, and a traction mechanism 3000; a door panel 2 is fixed on the platform 1000, a groove to be installed is opened on the front side of the door panel 2, a traction mechanism 3000 is arranged on the front side of the door panel 2, and a feeding mechanism 2000 is arranged at the left end of the front side of the door panel 2.

[0062] The feeding mechanism 2000 and the traction mechanism 3000 are both electrically connected to the control panel to realize automatic control; the traction mechanism 3000 is also provided with a safety alarm system.

[0063] The feeding mechanism 2000 includes a placement structure for placing the rubber strip 22, as well as a guide wheel group and a traction wheel group. The rubber strip 22 passes through the rigid core 23 and is placed outside the bracket groove 21. The rubber strip 22 is fed and delivered via the guide wheel and the traction wheel.

[0064] The traction mechanism 3000 includes a slide 600 and a track structure 800 which are slidably matched. A finger clamping cylinder 63 is provided on the slide 600. The finger heads of the finger clamping cylinder 63 are clamped by the rubber strip 22 and drive the rubber strip 22 to be inserted into the groove of the door panel 2 for insertion.

[0065] The platform 1000 includes a bracket 10, a rectangular reference surface platform 1, and a long surface platform 11; the rectangular reference surface platform 1 is fixed on the bracket 10, and is used to install and fix the door panel 2; a long surface platform is also placed on the bracket 10, and the long surface platform 11 is fixed on the bracket 10 after taking the front side of the reference surface platform 1 as the reference and resting against the front side, and the long surface platform 11 has a protrusion for installing the track. That is, the long surface platform 11 is aligned with the reference surface platform 1, and the protrusion on the long surface platform 11 ensures the accurate position of the installation track, thereby ensuring the position accuracy between the track and the door panel 2, and a machine for installing the rubber strip is set on the installation track.

[0066] In this scheme, if Figure 3 and Figure 4 As shown, in order to realize automatic positioning and fixing: on a rectangular reference surface table 1, a plurality of roller supports 3 for supporting the door panel 2 are arranged on its upper surface, and a positioning reference block 4, a positioning cylinder 5, a rear adjusting cylinder 6, and a right adjusting cylinder 7 are respectively arranged on the left side, front side, rear side, and right side of its upper surface, and force blocks are arranged at the output ends of the three cylinders; among them, the positioning cylinder 5 can move in the up and down direction; the rear adjusting cylinder 6 moves in the front and rear direction, and the right adjusting cylinder 7 moves in the left and right direction.

[0067] The principle of automatic adjustment and positioning is: put the door panel 2 roughly on the reference surface table 1, and the roller support 3 supports the door panel 2; then the rear adjustment cylinder 6 pushes the door panel 2 from the back to the front, and at the same time the right adjustment cylinder 7 pushes the door panel 2 from the right to the left, so that the left side of the door panel 2 is pushed to the positioning reference block 4 and is supported, and the front side of the door panel 2 is pushed to the positioning cylinder 5 and is supported. Thus, the automatic adjustment of the position is realized.

[0068] The positioning cylinder 5 can move in the up and down direction. When positioning is achieved, it retracts downward to avoid blocking the groove on the front side of the door panel 2 where the rubber strip 22 is to be installed, which is beneficial for the machine for installing the rubber strip 22 to install the rubber strip 22.

[0069] In this embodiment, the force bearing block of the positioning cylinder 5 is in a step shape. Figure 5 As shown, the step surface below is used to resist the front side of the door panel 2, and the step above it acts as a downward resistance force, so that when the door panel 2 automatically adjusts its position, it will not jump excessively.

[0070] Preferably, there are two positioning reference blocks 4, two positioning cylinders 5, two rear adjustment cylinders 6, and two right adjustment cylinders 7. Two points determine a line, ensuring that each side of the door panel 2 can be positioned.

[0071] After working for a period of time, due to the loosening of the screws, the positioning reference block 4 and the positioning cylinder 5 need to be calibrated. If there is a deviation, the groove on the front side of the door panel 2 where the rubber strip is to be installed and the mechanical position of the rubber strip installation may deviate, so that the rubber strip 22 cannot be installed.

[0072] In order to achieve the calibration of the positioning reference block 4: Figure 3 As described above, on the reference surface table 1, a calibration cylinder 8 is also provided on the left side of the positioning reference block 4, and a force block is also provided at the output end of the calibration cylinder 8; when the output end of the calibration cylinder 8 is extended, its force block is in the same plane as the positioning reference block 4. The calibration cylinder 8 is not extended to bear force at ordinary times, and when the rubber strip 22 is installed for a period of time, its output end is extended to allow the positioning reference block 4 to be calibrated to the same plane as the force block of the calibration cylinder 8.

[0073] In this embodiment, the roller support 3 includes two support plates 301 and a roller 302 , and the roller 302 is arranged between the two support plates 301 .

[0074] like Figure 3 and Figure 4 As shown, a roller support 3 is arranged at the front side of the upper surface of the reference surface table 1, and the surface of a support plate 301 of the roller support 3 is in the same plane as the surface of the force plate on the positioning cylinder 5. After the rubber strip 22 is installed for a period of time, the surface of the force block on the positioning cylinder 5 is calibrated with the surface of the support plate 301 as a reference.

[0075] In this embodiment, a notch is opened at the front side of the reference surface platform 1, and the positioning cylinder 5 is fixedly installed at the notch through the baffle seat 9.

[0076] For the feeding mechanism 2000, there are a guide wheel group and a traction wheel group; wherein the guide wheel group is arranged on the vertical substrate and limits the rubber strip 22 along the upper and lower sides, including an upper guide wheel 53 and a lower guide wheel 54; the traction wheel group is arranged on the vertical substrate, including a traction driving wheel 55 and a traction driven wheel 56.

[0077] In this solution, a strip plate 58 is installed at the upper end of the vertical base plate through an adjusting bolt A57, and the upper guide wheel 53 is installed on the strip plate 58; an ear seat plate 59 is fixed on the strip plate 58, and the traction driven wheel 56 is hinged on the ear seat plate 59; the strip plate 58, the adjusting bolt A57, and the upper guide wheel 53 form a height adjustment mechanism, and the traction driven wheel 56 and the ear seat plate 59 form an angle adjustment mechanism.

[0078] In this solution, the angle adjustment mechanism also includes a rotating block 50, and the traction driven wheel 56 is arranged on the rotating block 50; the rotating block 50 is hinged to the ear seat plate 59 through a rotating pin; a U-shaped notch is also opened on the rotating block 50, and an adjusting bolt B51 is passed through the U-shaped notch. The adjusting bolt B51 and the ear seat plate 59 can be screwed together to achieve angle locking.

[0079] It also includes placing structures, such as Fig.13 and Fig.14 As shown, the placement structure includes an outer support structure and an inner support structure, which install the rubber strip 22 from the inside and outside; and also includes a lateral clamping structure, which clamps and installs the rubber strip 22 from the front and back.

[0080] The outer support structure includes a bracket slot 21, the slot of which faces upwards, and the rubber strip 22 is inserted into the slot. The inner support structure includes a rigid core 23, which is inserted into the rubber strip 22 to keep the rubber strip 22 in a full state.

[0081] When installing the external and internal support structures, Figure 6 As shown: the right end of the rubber strip 22 extends out of the right end of the bracket groove 21, and the right end of the rigid core 23 extends out of the right end of the rubber strip 22. The bracket groove 21 only serves to support, and the rubber strip 22 extends out to facilitate installation in the groove of the door panel; the rigid core 23 extends out to facilitate subsequent extraction from the rubber strip 22.

[0082] In this solution, since the rigid core 23 only plays an internal supporting role and needs to be pulled out after installation, there is a clearance fit between the rigid core 23 and the rubber strip 22 .

[0083] As for the lateral clamping structure, it is arranged at the protruding end of the rubber strip 22, and includes a tightening mechanism and a pressing mechanism.

[0084] Specifically, the clamping mechanism includes a telescopic cylinder 24, which is connected to a base, and the base is slidably arranged on a support frame 31; an inverted T-shaped plate 33 is fixed on the upper surface of the base. The telescopic cylinder 24 is mounted on a long waist-shaped hole of the support frame 31 through a mounting frame, and the long waist-shaped hole is opened in the left-right direction.

[0085] The pressing mechanism includes a pressing cam 25 and a rotating shaft 26. The rotating shaft 26 is vertically arranged, and the pressing cam 25 is installed on the upper end of the rotating shaft 26. The pressing cam 25 is located in a horizontal plane and presses the rubber strip 22 from the front. When the rotating shaft 26 is rotated, the pressing cam 25 can adjust the pressing force on the rubber strip 22.

[0086] The clamping mechanism also includes a self-locking steering motor 29, the output end of which is meshed with a disc seat 28 through a gear, and a turntable 27 is provided at the lower end of the rotating shaft 26, and the turntable 27 is coaxially mounted on the disc seat 28 through bolts. The rotation adjustment of the clamping cam 25 is achieved by the self-locking steering motor 29.

[0087] When the clamping cam 25 rotates, the front and rear positions of the clamping point will change to a certain extent; in order to ensure that the end of the telescopic cylinder 24 is always opposite to the front and rear position of the clamping point of the clamping cam 25, the telescopic cylinder 24 is set in a position-adjustable manner.

[0088] In this embodiment, the cross section of the rubber strip 22 is C-shaped with its opening facing forward; the pressing cam 25 directly abuts against the rigid core 23 .

[0089] The traction mechanism 3000 includes a track structure 800 and a slide 600, which are slidably mounted.

[0090] In this solution, in order to realize the traction action, a spur rail 81 and two groove rails 82 parallel to each other are provided in the track structure 800; the bottom of the slide 600 is a slide base plate 61, which is slidably installed with the spur rail 81 through a slider 83, and the slide 600 outputs a short gear 7101 through the driving motor 71 to engage with the spur rail 81, thereby realizing the movement of the slide 600.

[0091] like Figure 7 As shown, the rubber strip 22 is located on one side of the insertion and traction mechanism, and a finger clamping cylinder 63 is provided on the slide 600 of the insertion and traction mechanism. The finger clamping cylinder 63 clamps the fake strip, and the slide 600 slides along the track structure 800, thereby realizing the insertion of the rubber strip 22.

[0092] During the insertion process, the smoothness of the operation of the slide 600, the position accuracy of the slide 600, and the position accuracy of the finger clamping cylinder 63 all affect the insertion of the rubber strip 22. For this reason, the structures of the track structure 800 and the slide 600 are designed.

[0093] A torque sensor is provided on the rotating shaft of the driving motor 71, and the torque sensor is electrically connected via an alarm to form a safety alarm system; when the torque exceeds or is less than the upper limit or lower limit set by the torque sensor, an alarm is sounded. When the torque formed on the rotating shaft of the driving motor 71 exceeds the set upper limit, it means that the rubber strip 22 does not correspond to the groove position of the door panel 2, and a certain part of the rubber strip 22 is excessively pressed against the groove of the door panel 2. When the torque is less than the lower limit, it means that the rubber strip 22 has fallen from the groove of the door panel 2. An alarm is sounded in both cases.

[0094] For the track structure 800, as Figure 7~Figure 9 As shown:

[0095] Place the straight-tooth rail 81 between two groove rails 82. Grooves are opened on both sides of the groove rail 82, and sliders 83 are adaptively installed thereon, that is, the positioning of the up-and-down position is realized. The slider base plate 61 of the slide table 600 is installed with a slider 83 through a bent plate 84. The bent plate 84 is L-shaped, and it is recessed downward at the right-angle position, and the recess is in the shape of an inverted "ji" character. The position where the "ji" character meshes with the gear 7101 and the straight-tooth rail 81 is at the same horizontal height.

[0096] The principle of the bent plate 84 in the shape of a "ji" character is as follows: When a force is generated between the gear 7101 and the straight-tooth rail 81, a force will be formed on the slide table 600 in the horizontal plane, so that the slide table 600 generates a force on the side of the slider 83 through the "ji" character part of the bent plate 84. Then, the height difference between this force and the force formed between the slider 83 and the groove rail 82 is very small, and the generated tipping force is very small, which is conducive to the stable operation of the slide table 600.

[0097] In this embodiment, the straight-tooth rail 81 includes a long strip 8101 and a rack 2101. The upper surface of the long strip 8101 is stepped. The rack 8102 is placed on this step and fixed by screws. This step is opposite to the bent part of the bent plate 84.

[0098] In this embodiment, a cover 85 is also provided outside the straight-tooth rail 81 and the groove rail 82 to prevent dust from having an adverse effect on the sliding.

[0099] For the slide table 600, as Figure 7~Figure 9 shown:

[0100] The slide table 600 includes a slide table base plate 61. A driving motor 71 is provided on the slide table base plate 61. The output end of the driving motor 71 passes through the slide table base plate 61, and the output end realizes the movement of the entire slide table through a gear.

[0101] A finger clamping cylinder 63 is also provided on the slide table base plate 61. The rubber strip 22 is clamped by the fingers of the finger clamping cylinder 63. When the slide table slides, the rubber strip 22 is driven to be inserted into the groove of the door panel 2 to achieve installation.

[0102] While realizing clamping and releasing, there is an action between the finger clamping cylinder 63 itself and the rubber strip 22. When inserting, its cylinder body first approaches the rubber strip 22, then clamps, and then the entire slide table slides; when the insertion is completed and the slide table needs to be reset, the clamping is released and the cylinder body moves away from the rubber strip 22. For this reason, this solution drives the finger clamping cylinder 63 to realize this action by setting a displacement cylinder 62.

[0103] During the insertion, the clamping accuracy must be met, which is achieved through the accuracy of the position and the stability and accuracy of the action. Otherwise, during the insertion, interference is likely to occur and the position of the rubber strip 22 is not installed well enough. Therefore, the structural design of the slide table in this scheme is as follows:

[0104] The overall design is as follows: on the slide base plate 61, two parallel sliding optical axes 68 are arranged through the support blocks, and the axial direction of the sliding optical axis 68 is perpendicular to the side of the rubber strip 22; on the sliding optical axis 68, a slidable displacement block 69 is adaptively shaped on the sliding optical axis 68, and a displacement base plate 67 is mounted on the displacement block 69, and the displacement base plate 67 is connected to the displacement cylinder 62 by driving; on the displacement base plate 67, a horizontally arranged I-shaped piece 64 is placed through a rectangular table 65, and a finger clamping cylinder 63 is respectively installed at both ends of the I-shaped piece 64, and the two finger clamping cylinders 63 clamp the rubber strip 22 together.

[0105] Since the precision cannot be achieved in one step during assembly, the finger clamping cylinder 63 clamps the rubber strip 22 from the upper and lower sides during the clamping process. Therefore, the distance between the upper and lower fingers and the rubber strip 22 is not necessarily equal, so they cannot be clamped with the same force, which easily causes the rubber strip 22 to deform. In order to be able to adjust, the rectangular table 65 is fixed on the displacement base plate 67, and the I-shaped piece 64 is placed horizontally and inverted on the rectangular table 65. The vertical plates at both ends of the I-shaped piece 64 form a gap with the rectangular table 65; and the I-shaped piece 64 is installed on the rectangular table 65 through the guide light axis 66. When adjustment is required, the height of the upper and lower fingers is measured, and then the height of the rubber strip 22 required to be installed at the door panel groove is measured. The height required to be adjusted is calculated, and the pad is placed at the gap between the vertical plate of the I-shaped piece 64 and the rectangular table 65. When selecting the pad, its thickness is required to be consistent with the height required to be adjusted. The accuracy of the adjustment is guaranteed.

[0106] When the finger clamping cylinder 63 on the I-shaped piece 64 clamps the rubber strip 22, the height position of the finger clamping cylinder 63 slides freely up and down along the guide optical axis 66 along the I-shaped piece 64, thereby achieving automatic adaptation and adjustment.

[0107] In order to fully utilize the efficiency of the displacement cylinder 62 and reduce friction, in this embodiment, the displacement block 69 is designed to be notched and H-shaped to reduce friction, and its notch position is adapted to be installed with the sliding optical axis 68. Reducing the friction between the displacement block 69 and the sliding optical axis 68 facilitates the displacement block 69 to move along the sliding optical axis 68.

[0108] In order to ensure sufficient action force and position accuracy of the displacement base plate 67 (the position accuracy of the displacement base plate 67 ensures the accuracy of the finger clamping cylinder 63), the displacement block 69 and the displacement base plate 67 adopt two design ideas. The first is to have a sufficiently large action force (needs to be debugged after installation), and the second is that the displacement base plate 67 has good position accuracy at the initial installation stage (basically no debugging is required after installation).

[0109] The first design, such as Fig.11 As shown in the figure, the displacement block 69 is in the shape of a horizontal plate, the displacement bottom plate 67 includes a horizontal part A6701 and a vertical part A702, between which a rib plate A6703 is arranged for strengthening the strength in the displacement direction, and the vertical part A702 is connected to the displacement cylinder 62. That is, the rib plate A6703 ensures the reliability between the horizontal part A6701 and the vertical part A702 on the one hand; on the other hand, when the displacement cylinder 62 is in motion, a large part of the pushing force generated by it is directly transmitted through the rib plate A6703, which has a very strong action force.

[0110] The second design, such as Fig.12 As shown: The second type, the displacement base plate 67 is in the shape of a horizontal plate; the displacement block 69 includes a horizontal portion B6901 and a vertical portion B6902, and a rib plate B903 is provided between the two for positioning the displacement base plate 67; the horizontal portion B6901 is in an H shape, and the vertical portion B6902 is connected to the displacement cylinder 62. The positioning principle of the rib plate B903 is that a notch matching the rib plate B903 is provided on the displacement base plate 67, and when the displacement base plate 67 is installed, the notch is clamped on the rib plate B903, and then fixed to the displacement block 69 by screws, without worrying about the error caused by tightening the screws.

[0111] In this embodiment, the displacement cylinder 62 is a three-axis cylinder, which is fixed on the slide base plate 61 through a support block. Its height is consistent with that of the I-shaped member 64 to ensure the stability and reliability of the action.

[0112] On the slide base plate 61, a guide groove 70 is provided through a support, and the guide groove 70 leads out the air pipe of the displacement cylinder 62, the air pipe of the finger clamping cylinder 63, and the wires through the wiring drag chain 86 to avoid the air pipe and the wires being clamped when the slide moves, which is conducive to the movement of the slide.

[0113] In this embodiment, the telescopic positioning cylinder 5, the rear adjustment cylinder 6, the right adjustment cylinder 7, and the calibration cylinder 8 in the platform 1000, the telescopic cylinder 24 and the self-locking steering motor 29 in the feeding mechanism 2000, and the displacement cylinder 62, the finger clamping cylinder 63, and the drive motor 71 in the traction mechanism 3000 are all electrically connected to the control panel, and the actions are automatically controlled by the control panel.

[0114] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
