Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, specifically relating to a transfer suction cup for rearview mirror glass. Background Technology

[0002] In the production and assembly of automotive rearview mirror glass, vacuum suction cup robotic arms are commonly used for gripping and transferring.

[0003] For example, CN220055492U discloses a suction cup for transferring tempered glass, including a base and a suction cup assembly. The suction cup assembly includes a cylinder, a rotating plate, and several suction cup components. One end of the rotating plate is rotatably connected to the base via a rotating shaft. One end of the cylinder is hinged to the top of the base, and the other end of the cylinder is hinged to the rotating plate. Several suction cup components are mounted on the rotating plate and evenly distributed on it. This invention can prevent the tempered glass from falling during transfer and is highly practical.

[0004] However, in actual use, the rearview mirror glass surface is prone to fine dust, fibers and other contaminants during production, storage and transportation. If it is directly adsorbed, these particles will be pressed between the suction cup and the glass, which will not only easily cause the adsorption to be weak and the glass to fall off.

[0005] Existing solutions involve either manual cleaning, which is inefficient, or the use of electric or pneumatic cleaning devices. However, electric and pneumatic devices have problems such as complex structure, high cost, need for additional energy and control circuits, and inconvenient maintenance. Utility Model Content

[0006] The purpose of this invention is to provide a transfer suction cup for rearview mirror glass to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a transfer suction cup for rearview mirror glass, comprising a fixed frame, a connecting arm fixedly connected to the center of the top of the fixed frame, and vacuum suction cups fixedly connected to the four corners inside the fixed frame, the vacuum suction cups being used to adsorb and fix the rearview mirror glass blank, and a cleaning component for assisting in cleaning the rearview mirror glass blank at the bottom of the fixed frame, the cleaning component comprising two swing arms symmetrically rotatably connected to the bottom of the fixed frame.

[0008] In a preferred embodiment, the two swing arms are arranged in a V-shape, and a cleaning roller is rotatably connected to the bottom of each swing arm.

[0009] In a preferred embodiment, guide grooves are provided inside the four corners of the fixing frame, and each guide groove is located on one side of a vacuum suction cup.

[0010] In a preferred embodiment, a guide post is fixedly connected inside the guide groove, and a sliding block is slidably connected outside the guide post. A spring sleeved on the outside of the guide post is fixedly connected between one end of the sliding block and one side of the inner cavity of the guide groove.

[0011] In a preferred embodiment, a connecting plate is rotatably connected to the opposite surface of the middle part of each swing arm, and the other end of each connecting plate is rotatably connected to the bottom of the sliding block above it.

[0012] In a preferred embodiment, one end of the two swing arms that contacts the fixed frame is rotatably connected to a second gear, and a first gear is rotatably connected to the center of the bottom of the fixed frame.

[0013] In a preferred embodiment, the bottom of the fixing frame is slidably connected to two synchronous racks on opposite sides of the first gear. Each of the two synchronous racks has a first transmission tooth that meshes with the first gear on the side facing the first gear, and a second transmission tooth that meshes with the second gear on the side facing the second gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This transfer suction cup for rearview mirror glass uses the downward pressing motion of the mechanical arm on the glass as a power source. The entire cleaning system is driven by the retraction of the swing arm. It eliminates the need for additional power components such as motors, cylinders, or solenoid valves, as well as their associated circuits and air lines, significantly reducing manufacturing costs and equipment complexity. It also eliminates the risk of electrical failures and improves the applicability and overall reliability of the system in special environments such as humid and explosion-proof environments. The cleaning roller completes the rolling cleaning action before the suction cup contacts the glass, eliminating the need to interrupt the transfer cycle for separate cleaning. This greatly improves the operating efficiency of the production line and avoids the time loss caused by manual intervention or independent cleaning stations.

[0016] The transfer suction cup for rearview mirror glass, through the setting of a synchronization mechanism consisting of a first gear, a second gear and a synchronous rack, forces the left and right swing arms and cleaning rollers to maintain symmetrical and synchronous movement during the retraction and opening process. This design effectively avoids the problem of jamming or uneven cleaning caused by unilateral resistance, ensuring that the pollutants in the adsorption area are removed smoothly and evenly to both sides, and the cleaning effect is thorough and consistent.

[0017] This transfer suction cup for rearview mirror glass features a swing arm connected to a spring-loaded sliding block via a connecting plate, forming a flexible buffer mechanism. This allows the cleaning roller to adaptively adjust pressure and closely conform to the curved surface when contacting rearview mirror glass with different curvatures. This ensures effective cleaning contact while preventing scratches or damage to the precision glass surface due to excessive rigid pressure. It is particularly suitable for high-quality lenses with coatings. The mechanism's built-in spring energy storage and reset system automatically and quickly pulls the cleaning component back to its initial "V"-shaped open state when the robotic arm is lifted after adsorption, without the need for additional drive. This ensures that every transfer operation starts with the same initial conditions, resulting in stable and reliable operation. Attached Figure Description

[0023] The present invention will be further described below with reference to the embodiments.

[0024] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the concept of the present invention all fall within the scope of protection claimed by the present invention.

[0025] Please see Figures 1-4This utility model provides a transfer suction cup for rearview mirror glass, including a fixed frame 1. A connecting arm 2 is fixedly connected to the center of the top of the fixed frame 1. Vacuum suction cups 3 are fixedly connected to the four corners inside the fixed frame 1. A cleaning assembly for auxiliary cleaning is provided at the bottom of the fixed frame 1. The cleaning assembly includes two swing arms 4 symmetrically rotatably connected to the bottom of the fixed frame 1. The two swing arms 4 are distributed in a V-shape, and a cleaning roller 5 is rotatably connected to the outside of the bottom end of each swing arm 4. Guide grooves 101 are opened inside the four corners of the fixed frame 1. Each guide groove 101 is located on one side of a vacuum suction cup 3. A guide post 403 is fixedly connected inside the guide groove 101. A sliding block 402 is slidably connected to the outside of the guide post 403. A spring 404 sleeved on the outside of the guide post 403 is fixedly connected between one end of the sliding block 402 and one side of the inner cavity of the guide groove 101. A connecting plate 401 is rotatably connected to the opposite surface in the middle of each swing arm 4. The other end of each connecting plate 401 is rotatably connected to the bottom of the sliding block 402 above it.

[0026] The transfer suction cup is in an idle state. At this time, the two swing arms 4 are opened in a figure-eight shape under the action of the spring 404. The cleaning roller 5 is located on the outside, the synchronous rack 6 is in a suitable position, the first gear 102 and the second gear 405 are in a relatively static initial meshing state, and the vacuum suction cup 3 does not adsorb the rearview mirror glass blank.

[0027] When in use, the robotic arm drives the entire transfer suction cup to move downward through the connecting arm 2, gradually approaching the rearview mirror glass blank. As it presses down, the cleaning roller 5 first contacts the surface of the rearview mirror glass blank. Due to the continuous pressing down of the robotic arm, the cleaning roller 5 is subjected to the reaction force of the rearview mirror glass. This force is transmitted to the swing arm 4, causing the swing arm 4 to start rotating around its rotation connection point with the fixed frame 1. The two swing arms 4 gradually expand to both sides.

[0028] While the cleaning roller 5 cleans the surface of the rearview mirror glass, as the robotic arm continues to press down, the vacuum suction cup 3 gradually contacts the surface of the rearview mirror glass. When it reaches the appropriate position, the vacuum adsorption device is activated, so that a negative pressure is formed inside the vacuum suction cup 3, thereby tightly adsorbing the rearview mirror glass.

[0029] The robotic arm drives the transfer suction cup holding the rearview mirror glass to rise and move through the connecting arm 2, transferring the rearview mirror glass to the designated position. During this process, the cleaning component remains relatively stationary and moves together with the suction cup.

[0030] Once the designated position is reached, the vacuum suction device is turned off, allowing the vacuum suction cup 3 to return to normal pressure. The rearview mirror glass separates from the suction cup, and then the robotic arm drives the transfer suction cup to rise via the connecting arm 2. At this time, the swing arm 4 is no longer subject to the reaction force of the rearview mirror glass. Under the action of the spring 404, the spring 404 pushes the sliding block 402 to slide on the guide post 403. The sliding block 402 drives the swing arm 4 to open outward through the connecting plate 401, returning to the initial figure-eight shape. At the same time, the rotation of the swing arm 4 drives the second gear 405 to rotate in the opposite direction. Then, through the transmission of the synchronous rack 6 and the first gear 102, it ensures that the two swing arms 4 and the cleaning roller 5 are synchronously and symmetrically reset, preparing for the next transfer operation.

[0031] Please see Figure 2 , Figure 3 and Figure 4 Two swing arms 4 are rotatably connected to one end of the contact end with the fixed frame 1 via a second gear 405. A first gear 102 is rotatably connected to the center of the bottom of the fixed frame 1. Two synchronous racks 6 are slidably connected to the bottom of the fixed frame 1 on both sides of the first gear 102 via a misalignment. The two synchronous racks 6 are provided with a first transmission tooth 601 that meshes with the first gear 102 on the side facing the first gear 102. The two synchronous racks 6 are provided with a second transmission tooth 602 that meshes with the second gear 405 on the side facing the second gear 405.

[0032] When the swing arm 4 rotates, it drives the second gear 405, which is rotated in a staggered manner with it, to rotate. Because the two synchronous racks 6 have second transmission teeth 602 that mesh with the second gear 405 on the side facing the second gear 405, the rotation of the second gear 405 will drive the synchronous racks 6 to move. At the same time, the two synchronous racks 6 have first transmission teeth 601 that mesh with the first gear 102 on the side facing the first gear 102. The movement of the synchronous racks 6 will drive the first gear 102 to rotate. The rotation of the first gear 102 further ensures the synchronous movement of the two synchronous racks 6. The meshing of the synchronous racks 6 with the second gear 405 forces the two swing arms 4 to always maintain symmetrical and synchronous retraction movements, so that the two cleaning rollers 5 can move smoothly and evenly to both sides to perform rolling sweeping cleaning on the rearview mirror glass surface and remove the pollutants in the adsorption area to both sides.

[0033] Using the action of the robotic arm pressing down on the rearview mirror glass as a power source, the swing arm 4 is driven to retract and drive the cleaning component to work. There is no need to equip it with additional power components such as motors, cylinders or solenoid valves, nor is there a need to set up matching circuits and air lines. This not only reduces the number of parts used and lowers material costs, but also simplifies the overall structure of the equipment, making the equipment easier to manufacture, thereby reducing manufacturing costs.

[0034] Since there are no electrical components, the risk of electrical faults, such as short circuits and leakage, is eliminated, which improves the stability of the equipment during operation. At the same time, this purely mechanical structure allows the transfer suction cup to work normally in special environments such as humid and explosion-proof environments, expanding the scope of application of the equipment and improving the overall reliability of the system.

[0035] The cleaning roller 5 can complete the rolling cleaning action before the suction cup contacts the rearview mirror glass. The entire cleaning process is seamlessly connected with the transfer process of the rearview mirror glass. There is no need to interrupt the transfer cycle for separate cleaning operations. This avoids the time loss caused by manual intervention or setting up independent cleaning stations, enabling the production line to operate continuously and efficiently, and greatly improving production efficiency.

[0036] The synchronization mechanism, consisting of the first gear 102, the second gear 405, and the synchronizing rack 6, ensures that the left and right swing arms 4 and the cleaning roller 5 maintain symmetrical and synchronized movement during the closing and opening process. This design effectively avoids jamming caused by different resistance on one side and uneven cleaning, ensuring that the pollutants in the adsorption area are removed smoothly and evenly to both sides, so that the glass surface is thoroughly and consistently cleaned, thus improving the quality of the product.

[0037] The working principle and usage process of this utility model are as follows: First, the robotic arm moves down via the connecting arm 2 with the suction cup. The cleaning roller 5 touches the rearview mirror glass blank first and continues to press down so that the reaction force is transmitted to the swing arm 4. The two swing arms 4 expand to both sides.

[0038] The rotation of the swing arm 4 drives the second gear 405 to rotate, the second gear 405 drives the synchronous rack 6 to move, and the synchronous rack 6 drives the first gear 102 to rotate, so that the two synchronous racks 6 move synchronously, thereby making the two swing arms 4 and the cleaning roller 5 move smoothly and evenly, and sweeping away the pollutants in the adsorption area.

[0039] While cleaning, the robotic arm continues to press down, and the vacuum suction cup 3 contacts the rearview mirror glass, activating the vacuum adsorption device, and the suction cup adsorbs the glass.

[0040] The robotic arm moves to the designated position via the connecting arm 2 and the vacuum suction cup 3 that adsorbs the rearview mirror glass, while the cleaning component moves stationary with the suction cup.

[0041] Upon reaching the designated position, the vacuum suction device is turned off, the rearview mirror glass separates from the vacuum suction cup 3, and the robotic arm rises with the vacuum suction cup 3. Spring 404 pushes sliding block 402, etc., to open and reset the swing arm 4. Simultaneously, gear and rack transmission ensures that both swing arms 4 and the cleaning roller 5 reset synchronously and symmetrically, preparing for the next operation.

[0042] It should be noted that the rearview mirror glass adsorbed in this application is an uncut large glass plate blank. In addition, the vacuum suction cup 3 and the connecting drive device (i.e., the mechanical arm or truss connected to the connecting arm 2, etc.) mentioned in this application are all mature components in the prior art. Their specific structure, vacuum generating device and control system are not the focus of improvement in this application. The core innovation of this application lies in the purely mechanical cleaning component integrated on the fixed frame 1.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
