Label pressing tool

Abstract

This application discloses a nameplate pressing fixture, relating to the field of automotive parts processing technology. It includes an upper pressure plate and a lower pressure plate arranged opposite each other, and a telescopic guide connecting the two. The upper pressure plate is configured to press relative to the lower pressure plate.

When the force applied by the upper pressure plate exceeds the elastic force of the spring head, the upper and lower pressure plates adhere together, applying pressure to the nameplate and triggering an elastic touch control to activate a timing feedback unit. The timing feedback unit emits an audible sound and starts timing. After pressing for five seconds, the timing feedback unit emits a prompt sound to indicate that pressing is complete. This achieves the pressing of the nameplate, thereby improving the pressing quality and avoiding insufficient pressing force that could lead to an unstable nameplate. Simultaneously, it reminds workers of the pressing time, significantly improving the installation efficiency of automotive nameplates.

Description

Technical Field

[0001] This application relates to the field of automotive parts processing technology, and in particular to nameplate pressing fixtures. Background Technology

[0002] A car badge is an identification component used to identify a car's brand, model, configuration, or function. It is typically installed in a prominent location on the vehicle, such as the front grille, rear trunk, side profile, or steering wheel. It not only serves as a core symbol of the vehicle's identity, allowing others to quickly recognize the brand and specific model, but some badges also indicate key vehicle information, such as engine displacement, drive type, or new energy vehicle attributes. Furthermore, it also serves a decorative purpose, enhancing the visual integrity of the vehicle.

[0003] To install a car emblem, you need to prepare the tools according to the emblem type (adhesive or screw-fixed). For adhesive emblems, you will need an adhesion promoter and a cleaning cloth; for screw-fixed emblems, you will also need a screwdriver or wrench. First, clean the surface of the car body at the installation location, wiping away dust and oil with a cloth. If necessary, wipe with alcohol to ensure there are no impurities to avoid affecting adhesion. Next, determine the installation position of the emblem. You can use tape for temporary positioning, ensuring it is aligned with the car body lines and not misaligned. If it is an adhesive emblem, peel off the protective film on the back of the emblem, apply a small amount of adhesion promoter evenly, and press the emblem firmly, keeping it for 3-5 minutes to ensure it is firmly attached. If it is a screw-fixed emblem, align it with the pre-drilled holes on the car body and tighten the screws with a tool to secure it. Finally, check whether the emblem is secure and the position is correct, avoiding any looseness or tilting.

[0004] In most existing adhesive nameplate installations, the protective film is first removed, then an adhesive agent is applied to the nameplate, and then a pressing tool is used to press it onto the vehicle panel to fix it. However, when pressing the nameplate, because the pressing tool is operated manually, the pressing force is often insufficient, resulting in unstable adhesion of the nameplate, which is detrimental to the production and processing of automotive parts. Summary of the Invention

[0005] The purpose of this application is to solve the problem in the above-mentioned background technology that when pressing the nameplate, the pressing tool is operated manually, which can easily lead to insufficient pressing force, resulting in unstable adhesion of the nameplate and thus being detrimental to the production and processing of automotive parts. This application provides a nameplate pressing tool.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] Signage pressing fixture, including:

[0008] The tooling body includes an upper pressure plate and a lower pressure plate arranged opposite to each other, and a telescopic guide connecting the two; the upper pressure plate is configured to perform a pressing movement relative to the lower pressure plate; the lower pressure plate is provided with a timing feedback unit for sensing the pressing action and timing; and the upper pressure plate is equipped with an elastic touch control.

[0009] A linkage mechanism is provided on the side of the upper pressure plate; the linkage mechanism includes a support frame and a guide member fixedly provided on the side of the upper pressure plate, the guide member is vertically arranged, and the support frame is sleeved on and slides on the outside of the guide member;

[0010] An auxiliary stabilizing component is installed at the bottom of the support frame and is used to adhere to the surface to be installed when pressed; the guide is configured to trigger the auxiliary stabilizing component to start adsorption during the sliding process of the upper pressure plate.

[0011] A limiting component is disposed on the support frame; the limiting component is configured to have a released state and a locked state; when the guide slides relative to the support frame to a predetermined pressing position, the limiting component switches to the locked state and forms a mechanical stop with the guide to limit the springback reset of the upper pressure plate.

[0012] By adopting the above technical solution, when installing a car emblem, the lower pressure plate can be aligned with the emblem. Then, the handle is pressed down, and pressure is applied to the upper pressure plate. When the force applied by the upper pressure plate is greater than the elastic force of the spring head, the upper and lower pressure plates adhere to each other and apply pressure to the emblem. This triggers the elastic touch control to activate the timing feedback unit, which then emits an sound and starts timing. After pressing for five seconds, the timing feedback unit emits a prompt sound to indicate that the pressing is complete. This achieves the pressing of the emblem, thereby improving the pressing quality and avoiding insufficient pressing force that could lead to the emblem not being securely fixed. At the same time, it can remind workers of the pressing time, significantly improving the installation efficiency of car emblems.

[0013] When the lower pressure plate is in contact with the sign, the auxiliary stabilizing component can be in contact with the vehicle panel. When the upper pressure plate is pressed down, the linkage mechanism can be driven simultaneously, causing the internal components of the linkage mechanism to operate and move synchronously towards the auxiliary stabilizing component. When the upper and lower pressure plates are in contact, the linkage mechanism can be triggered simultaneously, causing the auxiliary stabilizing component to quickly adhere to the vehicle panel, thereby achieving auxiliary fixation of the lower pressure plate and reducing the phenomenon of displacement when pressing the sign, further improving the stability of the sign during installation and maximizing the installation quality of the car sign.

[0014] Furthermore, a nameplate groove is provided at the bottom of the lower pressure plate, multiple spring heads are installed on the side of the lower pressure plate near the upper pressure plate, and a handle is fixedly connected to the top of the upper pressure plate.

[0015] By adopting the above technical solution, the structure of the sign slot is not unique and can be adjusted according to the shape of the pressed sign.

[0016] Furthermore, the elastic touch control includes a sleeve fixedly connected to the upper pressure plate, an inner rod slidably connected inside the sleeve, a lever fixedly connected to one end of the inner rod, and an abutment fixedly connected to the other side of the inner rod, and a spring is sleeved on the outer side of the inner rod, the spring being located between the sleeve and the lever.

[0017] By adopting the above technical solution, the pressing block causes the inner rod to move downward, thereby causing the contact head to re-contact the trigger point of the timing feedback unit, thus resetting the timing feedback unit.

[0018] Furthermore, a plurality of springs are fixedly connected to the inner bottom of the support frame, and one end of each spring is in contact with the guide member.

[0019] By adopting the above technical solution, when the upper pressure plate is pressed down, the guide can be driven to move downward in the support frame. When the upper pressure plate and the lower pressure plate are in contact, the bottom of the guide triggers the auxiliary stabilizing component. When the upper pressure plate loses its force, the guide can be pushed up by the elastic action of the second spring, so that the guide is reset and the contact with the auxiliary stabilizing component is released.

[0020] Furthermore, the auxiliary stabilizing component includes a control button fixedly connected to the bottom inner side of the support frame, a suction cup fixedly connected to the bottom of the support frame, an exhaust pipe fixedly connected to the top center of the suction cup, and suction pipes fixedly connected to both sides of the top of the suction cup.

[0021] By adopting the above technical solution, the operation of the auxiliary stabilizing component can be realized by triggering the control button.

[0022] Furthermore, a miniature negative pressure device is provided on one side of the exhaust pipe, and a vent valve is fixedly connected inside the intake pipe. Both the vent valve and the miniature negative pressure device are electrically connected to the control button.

[0023] By adopting the above technical solution, the miniature negative pressure device is turned on to extract the air inside the suction cup, while the vent valve is closed, so that a negative pressure is formed inside the suction cup, thereby assisting in fixing the lower pressure plate. When the contact with the control button is released, the miniature negative pressure device is turned off again, and the vent valve is reopened, allowing air to enter the suction cup through the suction pipe, thus releasing the negative pressure adsorption of the suction cup.

[0024] Furthermore, the limiting component includes a connecting box fixedly connected to one side of the support frame, a slider slidably installed inside the connecting box, a limiting block fixedly connected to one side of the slider, and an elastic lever installed on the other side of the slider.

[0025] By adopting the above technical solution, the slider can be positioned under the elastic action of spring three, so that the slider can drive the limiting block to slide out of the connecting box, thereby limiting and blocking the guide component.

[0026] Furthermore, the elastic lever includes a handle fixedly connected to one side of the slider, and a spring three is sleeved on the handle, the spring three being located between the slider and the connecting box.

[0027] By adopting the above technical solution, the slider can be pushed up by the elastic action of spring three, so that the slider drives the limit block to slide out of the connecting box, thereby limiting and blocking the guide. After the sign is pressed and fixed, the limit block can be pulled back into the connecting box by manually pulling the handle, thereby releasing the obstruction of the guide and realizing the automatic reset of the guide.

[0028] In summary, this application includes at least one of the following beneficial effects;

[0029] 1. In this application, when installing a car emblem, the lower pressure plate can be aligned with the emblem. Then, the handle is pressed down, and pressure is applied to the upper pressure plate. When the force applied by the upper pressure plate is greater than the elastic force of the spring head, the upper and lower pressure plates adhere to each other and apply pressure to the emblem. This triggers the elastic touch control to activate the timing feedback unit, which then emits an audible sound and starts timing. After pressing for five seconds, the timing feedback unit emits a prompt sound to indicate that the pressing is complete. This achieves proper pressing of the emblem, thereby improving the pressing quality and preventing insufficient pressing force from causing the emblem to be loosely fixed. At the same time, it can remind workers of the pressing time, significantly improving the installation efficiency of car emblems.

[0030] 2. In this application, when the lower pressure plate is attached to the sign, the auxiliary stabilizing component can be attached to the vehicle panel. When the upper pressure plate is pressed down, the linkage mechanism can be driven simultaneously, causing the internal components of the linkage mechanism to operate and move synchronously towards the auxiliary stabilizing component. When the upper and lower pressure plates are attached, the linkage mechanism can be triggered simultaneously, causing the auxiliary stabilizing component to quickly adhere to the vehicle panel, thereby achieving auxiliary fixation of the lower pressure plate, reducing the phenomenon of displacement when pressing the sign, further improving the stability of the sign during installation, and maximizing the installation quality of the car sign.

[0031] 3. In this application, when the linkage mechanism triggers the auxiliary stabilizing component, the internal components of the linkage mechanism release the restriction on the limiting component, allowing the internal components of the limiting component to extend, thereby restricting and locking the linkage mechanism after it is pressed down, and thus fixing the upper pressure plate. This makes the upper pressure plate, linkage mechanism and auxiliary stabilizing component form a stable force application point, improving the stability of the pressing force, reducing the phenomenon of insufficient force during pressing that leads to the sign not being securely fixed, further improving the quality of sign fixing, and at the same time saving the physical strength of the workers, making it easier for workers to install signs more efficiently and quickly, and improving fixing efficiency.

[0043] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0044] This application discloses a sign pressing tool.

[0045] Reference Figures 1 to 5 The sign pressing fixture includes: a fixture body, including an upper pressing plate 1 and a lower pressing plate 2 arranged opposite to each other, and a telescopic guide 9 connecting the two; the upper pressing plate 1 is configured to perform a pressing motion relative to the lower pressing plate 2; the lower pressing plate 2 is provided with a timing feedback unit 8 for sensing the pressing action and timing; and the upper pressing plate 1 is equipped with an elastic touch control 4.

[0046] Linkage mechanism 5 is located on the side of upper pressure plate 1; linkage mechanism 5 includes support frame 51 and guide member 52 fixedly installed on the side of upper pressure plate 1. Guide member 52 is vertically installed, and support frame 51 is sleeved and slides on the outside of guide member 52.

[0047] The auxiliary stabilizing component 6 is installed at the bottom of the support frame 51 and is used to adhere to the surface to be installed when pressed; the guide 52 is configured to trigger the auxiliary stabilizing component 6 to start the adsorption operation during the sliding process of the upper pressure plate 1.

[0048] Limiting component 7 is disposed on support frame 51; limiting component 7 is configured to have a released state and a locked state; when guide member 52 slides relative to support frame 51 to a predetermined pressing position, limiting component 7 switches to the locked state and forms a mechanical stop with guide member 52 to limit the springback reset of upper pressure plate 1;

[0049] The bottom of the lower pressure plate 2 is provided with a label groove 10, and multiple spring heads 21 are installed on the side of the lower pressure plate 2 near the upper pressure plate 1. A handle 3 is fixedly connected to the top of the upper pressure plate 1.

[0050] The elastic touch control 4 includes a sleeve 41 fixedly connected to the upper pressure plate 1. An inner rod 42 is slidably connected inside the sleeve 41. A lever 43 is fixedly connected to one end of the inner rod 42, and an abutment head 44 is fixedly connected to the other side of the inner rod 42. A spring 45 is sleeved on the outside of the inner rod 42. The spring 45 is located between the sleeve 41 and the lever 43. Here, the structure of the nameplate groove 10 is not unique and can be made and adjusted according to the shape of the nameplate being pressed. The timing feedback unit 8 consists of a timing unit and a trigger button. The trigger button is triggered by the elastic touch control 4, and the trigger button abuts the timing unit, causing the timing unit to start timing.

[0051] When bonding and fixing the sign to the vehicle panel, first apply adhesive to the sign. Then, place the adhesive-coated sign on the mounting point on the vehicle panel, and align the sign slot 10 with the sign. At this point, the auxiliary stabilizing component 6 is in contact with the vehicle panel. By manually pressing the handle 3, a force can be applied to the upper pressure plate 1. When the force applied by the upper pressure plate 1 is greater than the elastic force of the spring head 21, the upper pressure plate 1 and the lower pressure plate 2 are pressed together, applying pressure to the sign and triggering the contact head 44 to activate the timing feedback unit 8, which then emits a sound. The timing begins, and after pressing for five seconds, the timing feedback unit 8 emits a beep to indicate that the pressing is complete. After pressing, the toggle block 43 is pressed down, causing the inner rod 42 to move downwards, which in turn causes the contact head 44 to re-engage with the trigger point of the timing feedback unit 8, thereby resetting the timing feedback unit 8 for reuse. At this time, the operator needs to manually pull the limit component 7 to release the lock. Under the elastic action of the spring 45, the toggle block 43 and the contact head 44 can be reset, and the internal components of the linkage mechanism 5 can then spring back to their original positions.

[0052] When the lower pressure plate 2 is attached to the sign, the auxiliary stabilizing component 6 can be attached to the vehicle panel. When the upper pressure plate 1 is pressed down, the linkage mechanism 5 can be driven simultaneously, causing the internal components of the linkage mechanism 5 to operate and move synchronously towards the auxiliary stabilizing component 6. When the upper pressure plate 1 and the lower pressure plate 2 are attached, the linkage mechanism 5 can trigger the auxiliary stabilizing component 6, causing the auxiliary stabilizing component 6 to quickly adhere to the vehicle panel, thereby achieving auxiliary fixation of the lower pressure plate 2, reducing the phenomenon of displacement when pressing the sign, and further improving the stability of the sign during installation. After the sign is glued and fixed, the upper pressure plate 1 loses its force, and the internal components of the linkage mechanism 5 can spring back and reset, thereby canceling the touch of the auxiliary stabilizing component 6, releasing the adsorption of the auxiliary stabilizing component 6, and thus releasing the auxiliary fixation of the lower pressure plate 2.

[0053] When the linkage mechanism 5 triggers the auxiliary stabilizing component 6, the internal components of the linkage mechanism 5 release the restriction on the limiting component 7, allowing the internal components of the limiting component 7 to extend and thus restrict and lock the linkage mechanism 5 after it is pressed down, thereby fixing the upper pressure plate 1. This makes the upper pressure plate 1, the linkage mechanism 5, and the auxiliary stabilizing component 6 form a stable force application point, improving the stability of the pressing force and reducing the phenomenon of insufficient force during pressing that leads to the sign not being securely fixed, further improving the quality of sign fixing. After the sign is glued and fixed, the limiting component 7 can be manually pulled to cause the internal components of the limiting component 7 to retract, thereby releasing the restriction on the linkage mechanism 5 and causing the internal components of the linkage mechanism 5 to spring back and reset.

[0054] Reference Figures 6 to 8Multiple springs 53 are fixedly connected to the bottom inner side of the support frame 51. One end of the springs 53 contacts the guide 52. The auxiliary stabilizing component 6 includes a control button 62 fixedly connected to the bottom inner side of the support frame 51. A suction cup 61 is fixedly connected to the bottom of the support frame 51. An exhaust pipe 63 is fixedly connected to the top center of the suction cup 61. Suction pipes 64 are fixedly connected to both sides of the top of the suction cup 61. A miniature negative pressure device 66 is provided on one side of the exhaust pipe 63. A ventilation valve 65 is fixedly connected inside the ventilation pipe 64. Both the ventilation valve 65 and the miniature negative pressure device 66 are electrically connected to the control button 62.

[0055] When the upper pressure plate 1 is pressed down, the guide 52 moves downward within the support frame 51. When the upper pressure plate 1 and the lower pressure plate 2 are in contact, the bottom of the guide 52 triggers the control button 62. At this time, the miniature negative pressure device 66 is turned on to extract the air inside the suction cup 61, while the vent valve 65 is closed, creating a negative pressure inside the suction cup 61 to assist in fixing the lower pressure plate 2. When the upper pressure plate 1 loses its force, the guide 52 is pushed up by the elastic action of the second spring 53, causing the guide 52 to reset. At the same time, the contact with the control button 62 is released. Then, the miniature negative pressure device 66 closes again, and the vent valve 65 reopens, allowing air to enter the suction cup 61 through the suction pipe 64, thus releasing the negative pressure adsorption of the suction cup 61.

[0056] Reference Figure 9 The limiting component 7 includes a connecting box 71 fixedly connected to one side of the support frame 51. A slider 72 is slidably installed inside the connecting box 71. A limiting block 73 is fixedly connected to one side of the slider 72, and an elastic lever is installed on the other side of the slider 72. The elastic lever includes a handle 74 fixedly connected to one side of the slider 72. A spring 75 is sleeved on the handle 74. The spring 75 is located between the slider 72 and the connecting box 71.

[0057] When the guide 52 moves downward, it releases the restriction on the limiting block 73. Under the elastic action of the spring 75, the slider 72 is pushed up, causing the slider 72 to drive the limiting block 73 to slide out of the connecting box 71, thus limiting and blocking the guide 52. This fixes the upper pressure plate 1, making the upper pressure plate 1, the linkage mechanism 5, and the auxiliary stabilizing component 6 form a stable force application point, improving the stability of the pressing force, and reducing the phenomenon of insufficient force during pressing, which may cause the sign to be not securely fixed. After the sign is pressed and fixed, the limiting block 73 can be pulled back into the connecting box 71 by manually pulling the handle 74, thereby releasing the obstruction of the guide 52 and realizing the automatic reset of the guide 52.

[0058] Working principle: When bonding and fixing the sign to the vehicle panel, glue can be applied to the sign first. Then, the glued sign is placed on the mounting position on the vehicle panel, and the sign slot 10 is aligned with the sign. At this time, the auxiliary stabilizing component 6 is attached to the vehicle panel. By manually pressing the handle 3, a force can be applied to the upper pressure plate 1. When the force applied by the upper pressure plate 1 is greater than the elastic force of the spring head 21, the upper pressure plate 1 and the lower pressure plate 2 are attached and apply pressure to the sign, which drives the contact head 44 to trigger the timing feedback unit 8. The timing feedback unit 8 can then... A sound is emitted and the timer begins. After pressing for five seconds, the timing feedback unit 8 emits a prompt sound to indicate that the pressing is complete. After pressing, the toggle block 43 can be pressed down, causing the toggle block 43 to move the inner rod 42 downward, thereby causing the contact head 44 to re-contact the trigger point of the timing feedback unit 8, thus resetting the timing feedback unit 8 for easy reuse. At this time, the operator needs to manually pull the limit component 7 to release the lock. Under the elastic action of the spring 45, the toggle block 43 and the contact head 44 can be reset, and the internal components of the linkage mechanism 5 can then spring back to their original position.

[0059] When the lower pressure plate 2 is attached to the sign, the auxiliary stabilizing component 6 can be attached to the vehicle panel. When the upper pressure plate 1 is pressed down, the linkage mechanism 5 can be driven simultaneously, causing the internal components of the linkage mechanism 5 to operate and move synchronously towards the auxiliary stabilizing component 6. When the upper pressure plate 1 and the lower pressure plate 2 are attached, the bottom of the guide 52 triggers the control button 62. At this time, the micro negative pressure device 66 is turned on to extract the air inside the suction cup 61, while the vent valve 65 is closed, so that a negative pressure is formed inside the suction cup 61, thereby assisting in fixing the lower pressure plate 2 and reducing the phenomenon of displacement when pressing the sign, further improving the stability of the sign during installation. After the sign is glued and fixed, the upper pressure plate 1 loses its force, and the internal components of the linkage mechanism 5 can spring back and reset, thereby canceling the touch of the auxiliary stabilizing component 6, releasing the adsorption of the auxiliary stabilizing component 6, and thus releasing the auxiliary fixation of the lower pressure plate 2.

[0060] When the linkage mechanism 5 triggers the auxiliary stabilizing component 6, the restriction on the limiting block 73 can be released. Under the elastic action of the spring 75, the slider 72 can be pushed up, causing the slider 72 to drive the limiting block 73 to slide out of the connecting box 71, thereby limiting and blocking the guide 52, and thus fixing the upper pressure plate 1. This makes the upper pressure plate 1, the linkage mechanism 5, and the auxiliary stabilizing component 6 form a stable force application point, improving the stability of the pressing force and reducing the phenomenon of insufficient force during pressing, which may lead to the unreliable fixing of the sign. This further improves the fixing quality of the sign. After the sign is glued and fixed, the limiting component 7 can be pulled manually to make the internal components of the limiting component 7 contract, thereby releasing the restriction on the linkage mechanism 5 and causing the internal components of the linkage mechanism 5 to spring back and reset.
