Description

Technical Field

[0001] The invention relates to the field of automobile electronic instrument panel pointer assembly, and in particular to an automobile electronic instrument panel pointer assembly device and method. Background Art

[0002] The automotive electronic instrument panel is a combined interface of all the instruments in the car. It is a device used to display the working status of the car and is an interactive interface between people and cars. Pointers are set on the instrument panel. The assembly steps of the automotive electronic instrument panel include assembling the pointers on the instrument panel.

The driving mechanism drives the pointer pressure head to move above the pointer guide plate by driving the pointer pressure cylinder and presses the pointer placed on the instrument into the instrument motor shaft in sequence. Before assembly, use a clamp to fix the instrument on the pointer guide plate.

[0004] However, the prior art still has certain defects.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The invention discloses an automobile electronic instrument panel pointer assembly device. The automobile electronic instrument panel belongs to the field of automobile parts. The automobile electronic instrument panel pointer assembly device belongs to a type of industrial robot and a special operation robot. It is a device used to assemble a pointer on the automobile electronic instrument panel and has the functions of correcting the deviation and positioning of the automobile instrument panel and assembling the pointer.

[0043] like Figure 2-Figure 8 As shown, it mainly includes a base 1, a positioning frame 2 and an assembly component. The upper end of the base 1 is fixedly connected to the positioning frame 2, and the positioning frame 2 is provided with a device for aligning the instrument panel (shaped as Figure 1 As shown, a positioning component for positioning the side ears of the instrument panel is provided on the side, which is used to position and correct the instrument panel. An assembly component for installing a pointer is fixedly connected to the position of the base 1 on one side of the positioning frame 2. The assembly component can drive the pointer to move along the x-axis, y-axis, and z-axis, so that the designated assembly component drives the pointer to assemble at different positions of the instrument panel. The assembly component and the positioning component drive and cooperate;

[0044] The positioning assembly includes an inner clamp assembly and an outer support assembly, both of which are rotatably connected to the positioning frame 2, and the inner clamp assembly and the outer support assembly are respectively positioned on both sides of the instrument panel (because the instrument panel has a set of side ears on one side and two sets of side ears on the other side, such as Figure 1The inner clamping assembly clamps a group of side ears inward, and the outer supporting assembly supports from between the two groups of side ears to both sides, and is positioned through the side ears on both sides of the instrument panel) The positioning frame 2 is rotatably connected with a driving assembly, and the two ends of the driving assembly respectively drive the inner clamping assembly and the outer supporting assembly to rotate. A vertical gear 18 is fixedly connected to the middle of the side wall of the driving assembly, and a connecting plate 8 is fixedly connected to one side of the assembly assembly. The shape of the connecting plate 8 is set to be "L" type to prevent affecting the assembly of the pointer. A single-sided rack 9 is fixedly connected to the end of the connecting plate 8. The single-sided rack 9 is perpendicular to the upper end face of the machine base 1, and the single-sided rack 9 is plugged into the positioning frame 2, and the vertical gear 18 and the single-sided rack 9 are meshed for transmission.

[0045] The assembly position of the assembly component is adjusted according to the instrument panel model. After adjustment, the assembly component assembles the pointer to the position of the fixed three-dimensional coordinate, so the instrument panel positioning needs to be accurate.

[0046] When assembling the pointer of the instrument panel, the driving assembly component is lowered with the pointer close to the instrument panel. During this process, the single-sided rack 9 descends along with it. Since the single-sided rack 9 is meshed with the vertical gear 18, the single-sided rack 9 drives the driving assembly to rotate. The two ends of the driving assembly respectively drive the inner clamping assembly and the outer support assembly to operate simultaneously to correct the deviation and position the two sides of the instrument panel. When the instrument panel is corrected and positioned, the assembly component just drops to the specified height, and the assembly component clamps the pointer to be assembled on the motor shaft on the instrument panel. The assembly component can have an automatic loading function, which is the prior art and will not be repeated here. After a group of pointers are assembled, the automatic loading is used to assemble the pointers of other instruments on the instrument panel, and the pointers of all instruments on the instrument panel are assembled at one time. After assembly, the assembly component rises, driving the single-sided rack 9 to reversely drive the inner clamping assembly and the outer support assembly to operate, cancel the positioning, and facilitate the removal of the assembled instrument panel. In the process of the assembly component of this device descending to assemble the pointer of the instrument panel, the inner clamping assembly and the outer support assembly install, correct the deviation and position the instrument panel. The positioning and assembly are operated simultaneously to improve the assembly efficiency of the instrument panel pointer.

[0047] like Figure 5 , Figure 7 , Figure 8 As shown, a slide groove 42 and a slide groove 43 are provided at the lower end of the positioning frame 2, and the slide groove 42 and the slide groove 43 are arranged in parallel on both sides of the positioning frame 2. The inner clamping assembly includes a screw rod 12, and the screw rod 12 is rotatably connected in the positioning frame 2. One end of the screw rod 12 is rotatably connected to the inner wall of the positioning frame 2, and the other end is rotatably connected via a structural hoisting type. The side wall of the screw rod 12 is threadedly connected with two groups of clamping rods 13 for clamping one side of the instrument panel inwardly. The two groups of clamping rods 13 are both slidably connected in the slide groove 42, and a bevel gear 15 is fixedly connected to one end of the screw rod 12 close to the driving assembly.

[0048] Two sets of threads are arranged on the surface of the screw rod 12, and two sets of clamping rods 13 are respectively connected with the two sets of threads. When the screw rod 12 rotates, since the two sets of clamping rods 13 are slidably connected with the slide groove 42 and cannot rotate, the two sets of clamping rods 13 will move in opposite directions along the two sets of threads, so that the two sets of clamping rods 13 open and close, clamp a set of side ears of the instrument panel, so that one side of the instrument panel is corrected and positioned, and the bevel gear 15 facilitates the drive assembly to drive the screw rod 12 to rotate.

[0049] like Figure 5 , Figure 7 , Figure 8 As shown, the positioning frame 2 has two sets of moving components slidably connected inside, and the outer support component includes a screw rod 19, which is rotatably connected to the two sets of moving components. When the moving components slide to a certain position, one end of the screw rod 19 on the two sets of moving components just cooperates with one end of the driving component. The moving components not only do not hinder the rotation of the screw rod 19, but also can change the position of the screw rod 19. There is a certain damping between the inner wall of the moving component and the side wall of the screw rod 19, and a certain force needs to be applied to the screw rod 19 to The screw rod 19 can be rotated, and two groups of threads are arranged on the surface of the screw rod 19. The side wall of the screw rod 19 is threadedly connected with two groups of support rods 20 for supporting the instrument panel outwardly away from the side of the screw rod 12. The two groups of support rods 20 are respectively connected with the two groups of threads. The two groups of support rods 20 are both slidably connected with the slide groove 43. A bevel gear 3 21 is fixedly connected to one end of the screw rod 19 close to the driving assembly. A notch 11 is opened on one side of the positioning frame 2, and the notch 11 is connected with the slide groove 43. The two groups of support rods 20 are both matched with the notch 11.

[0050] When placing the instrument panel, first pull the support rod 20 by hand to rotate it into the notch 11, so that it is in a position parallel to the upper end of the machine base 1, and place the instrument panel on the machine base 1. At this time, the position of the instrument panel is offset, and the side of the instrument panel close to the clamping rod 13 is not guaranteed to fit with the clamping rod 13. Then push the support rod 20 to a position perpendicular to the upper end of the machine base 1. At this time, the support rod 20 is located in the notch 11, and the moving assembly drives the screw rod 19 to move, so that the screw rod 19 drives the two groups of support rods 20 to approach and squeeze the instrument panel, and squeeze and push the instrument panel to one side to fit with the clamping rod 13. The two sets of support rods 20 are supported from the middle of the two sets of side ears to the sides, and the instrument panel is corrected and positioned. At this time, one end of the screw rod 219 cooperates with the driving assembly, and the screw rod 219 rotates. Since the support rod 20 is in contact with one end of the notch 11 at this time, the support rod 20 cannot rotate toward the inside of the positioning frame 2. Therefore, the support rod 20 will slide along the side wall of the notch 11 into the inside of the slide groove 243, driving the two sets of support rods 20 to support from the middle of the two sets of side ears to the sides, correcting the deviation of one side of the instrument panel, and cooperating with the inner clamping assembly to realize the correction and positioning of both sides of the instrument panel, so as to prevent the position deviation of the instrument panel from affecting the assembly of the pointer.

[0051] After the assembly is completed, the driving assembly drives the inner clamping assembly and the outer support assembly to run in the opposite direction, so that the two groups of clamping rods 13 are separated and the two groups of support rods 20 are merged. When the support rods 20 move into the notch 11, the direction in which the support rods 20 are driven to merge is opposite to the direction in which the support rods 20 are driven to open. The support rods 20 rotate in the notch 11 until the support rods 20 in the notch 11 are parallel to the upper end surface of the base 1, so that the instrument panel can be easily pulled out from the upper end of the base 1.

[0052] like Figure 5 , Figure 8 As shown, the driving assembly includes a driving rod 16, which is perpendicular to screw rod 12 and screw rod 2 19, and is located between screw rod 12 and screw rod 2 19. The driving rod 16 is rotatably connected to the positioning frame 2, and both ends of the driving rod 16 are fixedly connected to bevel gear 2 17, bevel gear 1 15 and bevel gear 3 21 are respectively engaged with two groups of bevel gear 2 17 for transmission, and a vertical gear 18 is fixedly connected to the middle part of the side wall of the driving rod 16, and the single-sided rack 9 is engaged with the vertical gear 18 for transmission.

[0053] When the assembly pointer is lowered, the single-sided rack 9 drives the vertical gear 18 to drive the driving rod 16 to rotate, so that the bevel gear 2 17 at both ends of the driving rod 16 respectively drives the bevel gear 1 15 and the bevel gear 2 17 to rotate, thereby driving the inner clamping assembly and the outer support assembly to operate.

[0054] like Figure 5 , Figure 8 As shown, the moving assembly includes a sliding frame 22, and the screw rod 19 is rotatably connected to the two sets of sliding frames 22. There is damping between the inner wall of the sliding frame 22 and the side wall of the screw rod 19, which is similar to adding a sealing pad, an anti-skid pad or an elastic tooth structure between the contact surfaces of the two. It will not affect the driving assembly to drive the screw rod 19 to rotate, the deadweight of the support rod 20 will not drive the screw rod 19 to rotate, and the support rod 20 will not drive the screw rod 19 to rotate when it is squeezed by the instrument panel. Only when the support rod 20 is manually pulled to drive the screw rod 19 to rotate, or the driving assembly drives the screw rod 19 to rotate. 9 rotates, the upper end of the sliding frame 22 is slidably connected to the upper end of the inner wall of the positioning frame 2, and will not be separated from the upper end of the positioning frame 2. The side wall of the sliding frame 2 is fixedly connected with a double-sided rack 23. A through hole 28 is opened on one side of the positioning frame 2. One end of the double-sided rack 23 is plugged into the through hole 28. When the moving component moves, one end of the double-sided rack 23 passes through the through hole 28. Two sets of transmission components are arranged inside the positioning frame 2. The two sets of transmission components are respectively meshed with the two sets of double-sided racks 23 for transmission. The two sets of transmission components drive the two sets of moving components to move, so that both ends of the screw are subjected to force, so that the screw moves smoothly without tilting.

[0055] like Figure 5 , Figure 6 , Figure 8As shown, the transmission assembly includes a servo motor 24 (model TF-N20FN20), the servo motor 24 is fixedly connected to the inside of the positioning frame 2, and a driving gear 25 is fixedly connected to the output end of the servo motor 24. The servo motor 24 drives the driving gear 25 to rotate, and the driving gear 25 is parallel to the bottom wall of the positioning frame 2. The driving gear 25 is located below the double-sided rack 23, and the positions on both sides of the driving gear 25 inside the positioning frame 2 are rotatably connected with flat gears 26. The two groups of flat gears 26 are meshed with the driving gear 25 for transmission. The upper ends of the two groups of flat gears 26 are fixedly connected with arc-shaped toothed discs 27, and the two groups of arc-shaped toothed discs 27 are respectively matched with the two sides of the double-sided rack 23 for transmission.

[0056] When the servo motor 24 drives the driving gear 25 to rotate, the driving gear 25 drives the two sets of flat gears 26 to rotate in opposite directions, so that the two sets of arc-shaped toothed discs 27 rotate in opposite directions. When one set of arc-shaped toothed discs 27 drives the double-sided rack 23 to engage and transmit, the other set of arc-shaped toothed discs 27 is in a disengaged state from the double-sided rack 23. The two sets of arc-shaped toothed discs 27 respectively drive the double-sided rack 23 to move in opposite directions, thereby driving the moving component to slide.

[0057] like Figure 1 As shown, the assembly component includes a z-axis electric slide 5 (model TOYO-GTH8), which is fixed to the upper end of the machine base 1 at a position on one side of the positioning frame 2. The side wall of the z-axis electric slide 5 is slidably connected to a cross electric slide 3 (model CRS22-2022). The z-axis electric slide 5 drives the cross electric slide 3 and the connecting plate 8 to rise and fall. The cross electric slide 3 is located above the positioning frame 2. The moving end of the cross electric slide 3 is fixedly connected to a driving component 6 (the driving component 6 can be a device such as a press-fit cylinder), and the output end of the driving component 6 is fixedly connected to a mounting claw 7 for clamping and installing the pointer. The connecting plate 8 is fixedly connected to the side wall of one end of the cross electric slide 3.

[0058] During assembly, the z-axis electric slide 5 first drives the connecting plate 8 and the cross electric slide 3 down to a certain height to correct the deviation and position the instrument panel. The cross electric slide 3 is close to the upper end of the positioning frame 2. The cross electric slide 3 drives the driving part 6 to move to the specified position during the descending process. After the z-axis electric slide 5 stops running, the driving part 6 then drives the mounting claw 7 to descend, so that the clamping pointer of the mounting claw 7 is aligned with the motor shaft assembly pointer of the instrument panel.

[0059] like Figure 4As shown, a groove 29 is provided inside the base 1, and a supporting plate 30 is slidably connected in the groove 29. A reset component is fixedly connected between the bottom wall of the groove 29 and the lower end of the supporting plate 30. The supporting plate 30 is placed on the supporting plate 30 in the middle of the base 1. When the assembly component presses down the instrument panel to assemble the pointer, the supporting plate 30 is squeezed down by the instrument panel, and the reset component is compressed. The instrument panel is located in the groove 29 to prevent the instrument panel from being damaged due to excessive assembly force. The groove 29 is adapted to the shape of the instrument panel, which is convenient for positioning the instrument panel.

[0060] The reset assembly includes a fixing seat 1 44 and a fixing seat 2 45, which are respectively fixed to the lower end of the supporting plate 30 and the bottom of the groove 29, and the fixing seat 1 44 is symmetrically rotatably connected with two groups of connecting arms 1 31, and the ends of the two groups of connecting arms 1 31 are rotatably connected with connecting blocks 33, and the fixing seat 2 45 is symmetrically rotatably connected with two groups of connecting arms 2 32, and the ends of the two groups of connecting arms 2 32 are respectively rotatably connected with the two groups of connecting blocks 33, and a spring 1 34 is fixed between the two groups of connecting blocks 33.

[0061] The supporting plate 30 is pressed down, the two groups of connecting arms 1 31 and connecting arms 2 32 are opened, the spring 1 34 is stretched again, the elastic potential energy is increased, and a certain buffering effect is exerted on the assembly force. After assembly, the spring 1 34 pulls the two groups of connecting blocks 33 closer, the opening degree of connecting arms 1 31 and connecting arms 2 32 becomes smaller, the supporting plate 30 rises, and the instrument panel is supported above the base 1, so as to facilitate the removal of the assembled instrument panel.

[0062] like Figure 4 As shown, the side walls of the two groups of connecting arms 32 are rotatably connected with auxiliary rods 35, the ends of the auxiliary rods 35 are spherical, the ends of the two groups of auxiliary rods 35 are slidably connected to the bottom wall of the groove 29, and springs 36 are fixed between the ends of the two groups of auxiliary rods 35 and the fixed seat 45, and the springs 1 34 and 36 are both in a stretched state.

[0063] When the reset assembly is squeezed, the distance between the end of the auxiliary rod 35 and the second fixing seat 45 increases, and the second spring 36 is in a stretched state. When the reset assembly is reset, the second spring 36 pulls the end of the auxiliary rod 35 close to the second fixing seat 45, promoting the reduction of the opening degree of the second connecting arm 32, further facilitating the reset of the reset assembly.

[0064] like Figure 4As shown, receiving grooves 37 are provided on both sides of the inner wall of the groove 29, and damping plates 38 are slidably connected in the two groups of receiving grooves 37. The surfaces of the damping plates 38 close to the supporting plate 30 are set as inclined surfaces. The two groups of damping plates 38 are respectively squeezed and matched with the two sides of the supporting plate 30, and a spring 41 is fixedly connected between the damping plate 38 and the inner wall of the receiving groove 37. A magnetic block 39 is fixedly connected to one side of the damping plate 38 close to the inner wall of the receiving groove 37, and an electromagnet 40 is fixedly connected to the position of the inner wall of the receiving groove 37 corresponding to the magnetic block 39, and the electromagnet 40 is magnetically matched with the magnetic block 39.

[0065] When the device is in the state of being assembled, the electromagnet 40 is connected to the electromagnetic magnetic block 39 to shrink the damping plate 38 into the storage groove 37, and the spring three 41 is heavily compressed to prevent the upper end of the damping plate 38 from affecting the descent of the supporting plate 30. When the assembly is completed, the electromagnet 40 is powered off, and the spring three 41 squeezes the damping plate 38 so that the inclined surface of the damping plate 38 squeezes the side of the supporting plate 30, exerting a certain resistance and stabilizing force on the lifting of the supporting plate 30. The damping plate 38 slows down the speed at which the supporting plate 30 lifts the instrument panel to prevent the supporting plate 30 from moving too fast and causing the pointer to shake and loosen.

[0066] A method for assembling a pointer of an automobile electronic instrument panel, the method comprising the following steps:

[0067] S1. Preparation process

[0068] Place the instrument panel on the support plate 30, and place the pointer on the assembly component;

[0069] S2. Start assembling

[0070] Start the assembly component to make the pointer go down, and assemble the pointer at the designated position of the instrument panel. When the pointer goes down, the single-sided rack 9 goes down, and the single-sided rack 9 drives the driving component to rotate. The driving component drives the inner clamping component and the outer support component to run simultaneously to correct the deviation of the instrument panel. After the instrument panel is positioned, the assembly component assembles the pointer on the instrument panel to press the instrument panel down into the groove 29.

[0071] S3, assembly completed

[0072] After the assembly component assembles the pointer on the instrument panel, the reset component pushes the support plate 30 to lift, and the damping plate 38 slows down the speed of the support plate 30 lifting the instrument panel to prevent the pointer from shaking and loosening. The instrument panel is lifted onto the base 1, and the assembly component drives the single-sided rack 9 to lift, reversely drives the inner clamping component and the outer support component, cancels the positioning of the instrument panel, and then the instrument panel can be removed from the support plate 30.

[0073] The working principle of the automobile electronic instrument panel pointer assembly device and method provided by the present invention is as follows:

[0074] When placing the instrument panel, first pull the support rod 20 by hand to rotate it into the notch 11, and place the instrument panel on the supporting plate 30 of the machine base 1. At this time, the position of the instrument panel is offset, and then the support rod 20 is pushed to a position perpendicular to the upper end of the machine base 1. The moving assembly drives the screw rod 19 to move, so that the screw rod 19 drives the two groups of support rods 20 to approach and squeeze the instrument panel. After squeezing and pushing the instrument panel to the specified position, at this time, one end of the screw rod 19 cooperates with the driving assembly, and the assembly assembly runs. The driving assembly is driven by the single-sided rack 9 to run, so that the screw rod 19 and the screw rod 1 are moved. 12 rotates, the clamping rod 13 and the support rod 20 move, the instrument panel is corrected and positioned, the assembling component assembles the pointer, the instrument panel and the supporting plate 30 are pressed down into the groove 29, and after the assembly is completed, the assembling component is lifted, and the resetting component pushes the supporting plate 30 to lift, so that the assembled instrument panel can be taken out of the device, and the damping plate 38 slows down the speed of the supporting plate 30 lifting the instrument panel to prevent the pointer from shaking and loosening. The positioning component cancels the positioning of the instrument panel, and the instrument panel can be taken out of the device. The correction, positioning and assembly are carried out simultaneously to improve the efficiency of the instrument panel pointer assembly.
