Description

Technical Field

[0001] This invention relates to the field of needle indentation testing technology, specifically a needle indentation testing method and device for automotive dashboards. Background Technology

[0002] The car dashboard is a device that reflects the operating status of various vehicle systems. Common indicators include fuel gauge, washer fluid gauge, electronic throttle indicator, front and rear fog light indicators, and warning lights. The gauges on a car dashboard typically consist of a mounting cap and a pointer. To accommodate automated production, and because car gauges are precision instruments with high requirements for machining accuracy and quality, the mounting cap is prone to issues such as pointer tilting and unevenness exceeding tolerances. These problems can lead to inaccurate pointer readings, affecting the driver's judgment.

[0003] Chinese patent (application number CN202211512302.8) discloses a car dashboard needle detection device. The device uses a pressure head to press the pointer on the car dashboard, and a spring also acts as a buffer to protect the pointer. At the end of the pressing process, a fluorescent liquid is applied to the top of the pointer's cap. Subsequent laser irradiation makes it easy for the human eye to observe. The deformation of the applied fluorescent liquid is observed by the human eye to determine whether the pointer is tilted.

[0004] However, the aforementioned instrument panel needle pressure test has some problems in use:

[0005] The aforementioned needle pressure test addresses the unevenness and tilting issues that easily arise after instrument panel needle installation by pressing the needle with a pressure head and applying fluorescent liquid to the needle cap. However, judging whether the needle is in the correct position by observing the fluorescent illumination with the human eye is not accurate enough and is prone to misjudgment. Therefore, it cannot accurately guarantee whether the needle is in the correct position. Furthermore, when installing pointers in the instrument panel, the aforementioned device cannot perform mass installation of pointers for instrument panels of different specifications, resulting in low work efficiency.

[0006] Based on the above, a needle pressure testing method and device for automotive dashboards are proposed. Summary of the Invention

[0014] Preferably, a sliding member is closely attached to one side of the extrusion wheel and slides through the side plate.

The rightmost rotating shaft is slidably connected to the rectangular plate by an electric slider. A telescopic plate is fixedly installed on the upper part of the inner cavity of the long box. A tensioning wheel is fixedly installed on the telescopic end of the telescopic plate. The belt is located in the middle of the tensioning wheel.

[0015] Preferably, the contact cylinder is fixedly connected to the front plate, the contact cylinder has a movable cylinder inside, the movable cylinder has an S-shaped reset groove on the outside, a crossbar is fixedly installed on one side inside the contact cylinder, the crossbar is located in the reset groove, and a reset spring is installed between the top of the movable cylinder and the contact cylinder.

[0018] Preferably, another object of the present invention is to provide a detection method for a needle pressure testing device for an automotive dashboard, comprising the following steps:

[0019] S1: Needle insertion:

[0020] Move the sliding columns on both sides to place multiple instrument panels on the T-shaped plate in sequence. Then, under the action of the tension spring, the two abutment plates will move closer to each other to complete the positioning of the instrument panels. Then, turn on the electric slider to drive the half gear to rotate. When the half gear rotates, it drives the steering wheel to rotate, thereby realizing the intermittent release of the pressure needles on the upper and lower plates. The pressure needles fall to the middle of the instrument panel that has been fixed below.

[0021] S2: Continuous installation of pressure needles:

[0022] The electric slider is activated, causing the sprocket to rotate. The rotation of the sprocket drives the moving wheel to rotate, which in turn drives the synchronous wheel to rotate.

[0023] S3: Test after pressure pin installation:

[0024] When multiple installed pressure needles move to the bottom of the contact cylinder, the electric push rod opens and pushes forward to move the long box down. When the long box moves down, it simultaneously drives the moving cylinder down. When the moving cylinder moves down, it first contacts the pressure needle and then moves up due to the reaction force. It slides in the reset groove through the crossbar. The moving cylinder moves up and rotates at the same time, thereby pressing and rotating the pressure needle, thus aligning the pressure needle.

[0025] The beneficial effects of this invention are:

[0026] 1. This invention enables multiple upper side plates to synchronously drive multiple T-shaped plates to adjust at equal distances by adjusting the distance between the two E-shaped plates, so as to perform batch continuous needle press tests on instrument panels of different specifications. Furthermore, the adjustment of the distance between the T-shaped plates is also used to control the speed at which multiple instrument panels move during needle press.

[0027] 2. This invention uses an electric slider to drive the sprocket to rotate. When the sprocket rotates, it drives the moving wheel to rotate via a chain. When the moving wheel rotates, it drives the synchronous wheel to rotate synchronously. When the synchronous wheel rotates, it meshes with the toothed plate, thereby causing the long plate to move intermittently to the left. When the long plate moves intermittently to the left, it causes multiple instrument panels that are fixed on the long plate to move to the left in sequence, thereby realizing the continuous needle insertion of a batch of instrument panels.

[0028] 3. In this invention, when the moving cylinder moves downward, it first contacts the pressure needle and then moves upward due to the reaction force. The moving cylinder slides in the reset groove through the crossbar and rotates while moving upward, thereby pressing and rotating the pressure needle, and thus aligning the pressure needle.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1 , Figure 5 , Figure 8 As shown, a needle detection device for an automotive dashboard includes a base plate 10. Two symmetrically arranged mounting brackets 21 are fixedly installed on the upper surface of the base plate 10. Four sliding rods 22 are installed between the mounting brackets 21 on both sides. A support plate 29 is fixedly installed on each of the two sliding rods 22 on one side. A long plate 27 is placed on the upper surface of the two support plates 29. Guide grooves 271 are opened on both sides of the upper surface of the long plate 27. A sliding frame 272 is slidably installed between the guide grooves 271 on both sides. Multiple sets of sliding frames 272 are provided. A T-shaped plate 273 for placing the dashboard is fixedly installed on the upper surface of the sliding frame 272. A rectangular frame 31 is fixedly installed on one side of the long plate 27.

[0049] A middle frame 32 is installed on both sides of the inner side of the rectangular frame 31. An E-type plate 33 is slidably installed on the side of the middle frame 32 closest to each other. A lower side plate 34 is fixedly installed on the lower end face of one E-type plate 33, and an upper side plate 35 is fixedly installed on the upper end face of the other E-type plate 33. The sides of the upper side plate 35 and the lower side plate 34 away from the E-type plate 33 are respectively fixedly connected to corresponding T-type plates 273. By adjusting the distance between the two E-type plates 33, multiple upper side plates 35 can synchronously drive multiple T-type plates 273 to adjust the distance between them equally. This allows for batch continuous needle pressure testing of instrument panels of different specifications. Furthermore, the adjustment of the distance between the T-type plates 273 is also used to control the movement of multiple instrument panels. The speed of movement during needle placement is determined by the following: A fixing plate 41 is fixedly installed on the rear of the upper surface of the base plate 10. An electric push plate 42 is installed on the front side of the fixing plate 41. A hanging plate 43 is installed between the two electric push plates 42. A protruding plate 44 is fixedly installed in the middle of the hanging plate 43. An electric push rod 45 is fixedly installed on the lower side of the protruding plate 44. A long box 46 is fixedly installed at one end of the electric push rod 45. A contact cylinder 51 for detecting and resetting the needles on the instrument panel is provided on the front side of the long box 46. The electric push plate 42 is pushed forward to move the hanging plate 43 to the top of multiple instrument panels that have completed needle placement. Then, the electric push rod 45 is pushed down to drive the contact cylinder 51 to press down and fix the needles installed on the instrument panel and align them.

[0050] A bracket 23 is mounted between multiple sliding rods 22. Sprockets 24 are rotatably mounted on both sides of the upper surface of the bracket 23 via electric sliders. The sprockets 24 are driven by a chain 25. A movable wheel 26 is rotatably mounted in the middle of the chain 25. A toothed plate 270 is fixedly mounted on one side of the lower surface of the long plate 27. A synchronous wheel 28, rotatably connected to the long plate 27, meshes with one side of the toothed plate 270. Four arc-shaped grooves 274 are formed in the middle of the T-shaped plate 273. Sliding columns 275 are slidably mounted in the middle of the arc-shaped grooves 274. A tension spring 276 is mounted between two sliding columns 275 on the same side. The upper surfaces of the two side sliding columns 275 and the two rear sliding columns 275 are all fixedly equipped with abutment plates 277. The electric slider opens and drives the sprocket 24 to rotate. When the sprocket 24 rotates, it drives the moving wheel 26 to rotate through the chain 25. When the moving wheel 26 rotates, it drives the synchronous wheel 28 to rotate synchronously. When the synchronous wheel 28 rotates, it meshes with the toothed plate 270, thereby driving the long plate 27 to move intermittently to the left. When the long plate 27 moves intermittently to the left, it drives the multiple instrument panels that are fixed on the long plate 27 to move to the left in sequence, thereby realizing the continuous needle insertion of a batch of instrument panels.

[0051] A center plate 36 is fixedly installed in the middle of the lower end face of the rectangular frame 31. A control rod 37 is threadedly installed in the middle of the center plate 36. A cam 38 is fixedly installed on the outside of the control rod 37. Pull plates 39 are rotatably installed on both sides of the cam 38. One side of the pull plate 39 is rotatably connected to the E-type plate 33. By moving the two abutment plates 277, the abutment plates 277 move synchronously, driving the two sliding columns 275 on the left and right sides to move in the arc groove 274, placing the instrument panel between the two abutment plates 277. Then, under the action of the tension spring 276, the two abutment plates 277 move closer to each other to complete the fixation of the instrument panel, so as to put the needle into the instrument panel later. Rotating the control rod 37 drives the cam 38 to rotate. When the cam 38 rotates, it pulls the E-type plates 33 on both sides through the pull plates 39 on both sides. When the distance between the two E-type plates 33 is adjusted, the distance between the multiple T-type plates 273 is adjusted through the lower side plate 34 and the upper side plate 35.

[0052] like Figure 10 , Figure 11 , Figure 13 As shown, a movable groove 461 is provided on the front side of the long box 46, and multiple sets of rectangular plates 462 are provided in the rear part of the inner cavity of the long box 46. The rightmost rectangular plate 462 is fixedly connected to the long box 46, and multiple rectangular plates 462 on the right side are slidably connected to the long box 46. A pressing wheel 463 is rotatably installed on the front side of the rectangular plate 462 through a rotating shaft, and a side plate 464 fixedly connected to the long box 46 is provided on one side of the pressing wheel 463.

[0053] A sliding piece 465 is attached to one side of the extrusion roller 463 and slides through the side plate 464. A pulley 466 is fixedly installed on the front side of the rotating shaft in the middle of the extrusion roller 463. A belt 467 is installed between the pulleys 466. The rightmost rotating shaft is slidably connected to the rectangular plate 462 by an electric slider. A telescopic plate 468 is fixedly installed on the upper part of the inner cavity of the long box 46. A tensioning wheel 469 is fixedly installed on the telescopic end of the telescopic plate 468. The belt 467 is located in the middle of the tensioning wheel 469. A front plate 5 is fixedly installed on the front of the rectangular plate 462.

[0054] The contact cylinder 51 is fixedly connected to the front plate 5. The contact cylinder 51 has a movable cylinder 52 inside. The movable cylinder 52 has an S-shaped reset groove 53 on the outside. A crossbar 54 is fixedly installed on one side inside the contact cylinder 51. The crossbar 54 is located in the reset groove 53. A reset spring 55 is installed between the top of the movable cylinder 52 and the contact cylinder 51. The electric slider is opened to drive the extrusion wheel 463 to rotate. When the extrusion wheel 463 rotates, it drives the adjacent rectangular plate 462 to slide through the sliding member 465. This allows the distance between the multiple front plates 5 and the multiple contact cylinders 51 to be adjusted so that the distance between them is consistent with the distance between the multiple instrument panels. This is so that the multiple instrument panels that have completed the needle insertion can be tested in the future.

[0055] like Figure 2, Figure 3 , Figure 4 As shown, a support frame 11 is fixedly installed on one side of the upper surface of the substrate 10, and a feeding hopper 18 is fixedly installed on one side of the support frame 11. A fixing box 12 fixedly connected to the substrate 10 is provided below the feeding hopper 18. A half gear 121 is rotatably installed on one side of the inside of the fixing box 12 via an electric slider. A steering wheel 122 rotatably connected to the fixing box 12 is meshed on one side of the half gear 121. A hydraulic rod 13 is fixedly installed on the upper end face of the steering wheel 122.

[0056] A rotating cylinder 14 is sleeved around the hydraulic rod 13. An upper plate 15 is fixedly installed on the top of the hydraulic rod 13. A lower plate 16 connected to the rotating cylinder 14 is located below the upper plate 15. Inner cylinders 151 are fixedly installed on both sides of the upper plate 15, and outer cylinders 161 are fixedly installed on both sides of the lower plate 16. An electric slider is used to open and drive the half gear 121 to rotate. When the half gear 121 intermittently drives the steering wheel 122 to rotate, it synchronously drives the hydraulic rod 13 to rotate. When the hydraulic rod 13 rotates, it drives the upper plate 15 and the lower plate 16 to rotate synchronously. At this time, the two inner cylinders 151 on the upper plate 15 rotate sequentially into the hopper 18 to receive the pressure needles. A fixing block 141 fixedly connected to the base plate 10 is provided on one side of the hydraulic rod 13. A slide cylinder 142 is slidably installed in the middle of the fixed block 141. The top of the slide cylinder 142 is rotatably connected to the rotating cylinder 14. A rack 162 is fixedly installed in a groove on one side of the slide cylinder 142. A shaped frame 163 fixedly connected to the base plate 10 is provided on one side of the rack 162. A control wheel 164 is rotatably installed in the shaped frame 163 via an electric slider. A control ring 17 is fixedly installed on the top of the slide cylinder 142. Opening and closing plates 171 hinged to the outer cylinder 161 are rotatably installed on both sides of the lower end face of the control ring 17. When the electric slider is opened, it drives the control wheel 164 to rotate. When the control wheel 164 rotates, it engages with the rack 162 to realize the lifting and lowering of the slide cylinder 142. When the slide cylinder 142 is lifted and lowered, it drives the control ring 17 to lift and lower. At this time, in conjunction with the rotation of the steering wheel 122, the opening and closing plate 171 on one side can be flipped to open the outer cylinder 161 on one side. At this time, the pressure needle in the outer cylinder 161 falls to complete the installation between it and the instrument panel.

[0057] like Figures 1-15 As shown, another object of the present invention is to provide a detection method for a needle pressure testing device for an automotive dashboard, comprising the following steps:

[0058] S1: Needle insertion:

[0059] Move the sliding columns 275 on both sides to place multiple instrument panels on the T-shaped plate 273 in sequence. Then, under the action of the tension spring 276, the two abutment plates 277 are brought closer to each other to complete the positioning of the instrument panel. Then, the electric slider is turned on to drive the half gear 121 to rotate. When the half gear 121 rotates, it drives the steering wheel 122 to rotate, thereby realizing the intermittent release of the pressure needles on the upper plate 15 and the lower plate 16. The pressure needles fall to the middle of the instrument panel that has been fixed below.

[0060] S2: Continuous installation of pressure needles:

[0061] The electric slider is activated, causing the sprocket 24 to rotate. When the sprocket 24 rotates, it drives the movable wheel 26 to rotate. When the movable wheel 26 rotates, it synchronously drives the synchronous wheel 28 to rotate. When the synchronous wheel 28 rotates, it engages with the toothed plate 270, thereby making the long plate 27 cooperate. The pressure needle is intermittently moved forward.

[0062] S3: Test after pressure pin installation:

[0063] When multiple installed pressure needles move to below the contact cylinder 51, the electric push rod 45 opens and pushes forward to move the long box 46 down. When the long box 46 moves down, it simultaneously drives the moving cylinder 52 down. When the moving cylinder 52 moves down, it first contacts the pressure needle and then moves up due to the reaction force. It slides in the reset groove 53 through the crossbar 54. The moving cylinder 52 moves up and rotates at the same time, thereby pressing and rotating the pressure needle, and thus aligning the pressure needle.

[0064] In use, the invention first moves two abutment plates 277. As the abutment plates 277 move, they simultaneously drive two sliding pillars 275 on the left and right sides to move within the arc groove 274, placing the instrument panel between the two abutment plates 277. Then, under the action of the tension spring 276, the two abutment plates 277 move closer to each other, thus fixing the instrument panel. The above operation is repeated to fix a batch of instrument panels on the T-shaped plates 273. Then, the spacing between the T-shaped plates 273 is adjusted according to the specifications of the instrument panel. The control lever 37 is rotated, which drives the cam 38 to rotate. When the cam 38 rotates, it pulls the E-shaped plates 33 on both sides through the pull plates 39 on both sides. When the spacing between the two E-shaped plates 33 is adjusted, the spacing between multiple T-shaped plates 273 is adjusted through the lower side plate 34 and the upper side plate 35, so as to perform continuous needle-pressing tests on batches of instrument panels of different specifications. Furthermore, the spacing adjustment between the T-shaped plates 273 is also used to control the speed at which multiple instrument panels move during needle-pressing.

[0065] Subsequently, the electric slider opens, driving the half gear 121 to rotate. The half gear 121 intermittently drives the steering wheel 122 to rotate, simultaneously driving the hydraulic rod 13 to rotate. The rotation of the hydraulic rod 13 drives the upper plate 15 and lower plate 16 to rotate synchronously. At this time, the two inner cylinders 151 on the upper plate 15 rotate sequentially into the hopper 18 to receive the pressure needles. The electric slider opens, driving the control wheel 164 to rotate. When the control wheel 164 rotates, it meshes with the rack 162, thereby raising and lowering the slide cylinder 142. The raising and lowering of the slide cylinder 142 drives the control ring 17 to rise and fall. This, combined with the rotation of the steering wheel 122, allows the opening and closing plate 171 on one side to move. The outer cylinder 161 on one side is flipped open, and the pressure needle inside the outer cylinder 161 falls to complete the installation with the instrument panel. At this time, the instrument panel moves to the left in sequence, the electric slider opens and drives the sprocket 24 to rotate. When the sprocket 24 rotates, it drives the moving wheel 26 to rotate through the chain 25. When the moving wheel 26 rotates, it drives the synchronous wheel 28 to rotate. When the synchronous wheel 28 rotates, it meshes with the toothed plate 270, thereby driving the long plate 27 to move to the left intermittently. When the long plate 27 moves to the left intermittently, it drives the multiple instrument panels that are fixed on the long plate 27 to move to the left in sequence, thereby realizing the continuous injection of pressure needles for a batch of instrument panels.

[0066] After the pressure needles on the instrument panel are installed, the electric push plate 42 pushes forward, causing the hanging plate 43 to move above the multiple instrument panels where the pressure needles have been placed. The electric push rod 45 opens and pushes forward, causing the long box 46 to move down. When the long box 46 moves down, it simultaneously drives the moving cylinder 52 to move down. When the moving cylinder 52 moves down, it first contacts the pressure needle and then moves up due to the reaction force. It slides in the reset groove 53 through the crossbar 54. The moving cylinder 52 moves up and rotates at the same time, thereby pressing and rotating the pressure needle, and thus aligning the pressure needle.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
