Description

Technical Field

[0001] This utility model relates to the field of gearbox assembly equipment, and specifically to a gasket assembly mechanism. Background Technology

[0002] In the production and assembly of gearboxes, gaskets are key components that ensure the sealing performance of the gearbox and adjust the clearance between parts. Their assembly quality directly affects the overall performance of the gearbox. Currently, the assembly of gaskets in gearbox assembly relies heavily on manual operation. However, during the production and storage process, rust-preventive oil is applied to the gaskets, which can easily cause multiple gaskets to stick together, making it difficult for manual workers to accurately separate individual gaskets.

[0003] This manual assembly method has the following drawbacks: Low assembly accuracy: Due to the adhesion of gaskets, multiple pieces are easily stacked during manual separation, which leads to abnormal gearbox clearance, seal failure, and increased product rework rate. Low assembly efficiency: Manually separating the adhered gaskets requires repeated confirmation and adjustment, which is time-consuming and difficult to keep up with the pace of mass production of gearboxes; High labor costs: Specialized operators are required to monitor the gasket assembly process, and the operators' skill level is high, which increases labor costs in the production process.

[0004] Therefore, there is an urgent need for a mechanism that can automatically separate, transfer, and position gaskets for assembly, in order to overcome the shortcomings of existing manual assembly methods and improve the accuracy and efficiency of gearbox assembly. Utility Model Content

[0005] In view of the above, the purpose of this utility model is to overcome the defects of the existing technology in gearbox gasket assembly, which relies on manual labor and is prone to multiple pieces being assembled due to gasket adhesion. It provides a gasket assembly mechanism that realizes automated single-piece separation, transfer, positioning and assembly of gaskets, improves assembly accuracy and efficiency, and reduces manual intervention.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: A gasket assembly mechanism mainly includes a gasket feeding and distributing unit, a gasket transfer unit, and a gasket positioning and secondary transfer unit.

[0007] The gasket feeding and dispensing unit is used to store stacked gaskets and separate them into individual pieces. Its core component is a gasket dispensing cylinder. Preferably, the unit also includes a hopper formed by four guide rods arranged in a matrix for storing gaskets. A support plate is provided at the bottom of the hopper, and the gasket dispensing cylinder is located below the hopper, with its output end connected to a material plate. The material plate is attached to the bottom of the support plate, and a material groove adapted to the inner cavity of the hopper is formed on the material plate. Driven horizontally by the gasket dispensing cylinder, the material plate can receive and remove the bottommost gasket, achieving precise single-piece separation.

[0008] The gasket transfer unit is used to transfer the separated single gaskets from the material sorting station to the positioning station. It includes a first lifting drive component, a first vacuum suction cup, and a horizontal movement module. The first lifting drive component drives the first vacuum suction cup to lift and lower to pick up or release the gasket, while the horizontal movement module drives the entire first lifting drive component and the first vacuum suction cup to move horizontally between the material sorting unit and the positioning secondary transfer unit.

[0009] The gasket positioning and secondary transfer unit is located at the intermediate positioning station and includes a positioning cylinder, a second lifting drive component, a second vacuum suction cup, and a lateral movement drive component. The positioning cylinder is used to precisely position the gasket placed by the first vacuum suction cup. The second lifting drive component drives the second vacuum suction cup to rise and fall to pick up the positioned gasket, while the lateral movement drive component moves the second vacuum suction cup between the intermediate positioning station and the final product assembly station to complete the final assembly of the gasket.

[0010] Further, the first lifting drive component may specifically include a first lifting cylinder and a first fixed plate, with a first vacuum suction cup evenly mounted on the first fixed plate. The horizontal movement module is preferably a servo electric slide. The positioning cylinder is preferably a bidirectional clamping cylinder, with a clamping rod fixed to its clamping head for clamping and positioning. The second lifting drive component may include a fixed base, a lifting slide, and a second cylinder, with a second vacuum suction cup mounted on the bottom of the lifting slide. The transverse movement drive component includes a guide rail and a third cylinder for driving the fixed base to move.

[0011] The beneficial effects of this utility model are as follows: High degree of automation: It realizes full-process automation from gasket material distribution, transfer, positioning to final assembly, which significantly reduces labor costs and labor intensity.

[0012] High reliability of the slab separation: Through the precise cooperation of the hopper, material plate and gasket dispensing cylinder, the bottom gasket is mechanically separated, which effectively overcomes the problem of multiple gaskets being picked up at the same time due to oil stains and ensures the accuracy of the number of assembled gaskets.

[0013] Precise positioning: The gasket is pre-positioned by a positioning cylinder, and combined with high-precision transmission components such as a servo module, the positional accuracy of the gasket during assembly is guaranteed, thus improving product quality.

[0014] Efficiency Improvement: The smooth and short cycle time of each unit greatly improves the assembly efficiency of the gaskets, making it suitable for large-scale production lines. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1 to 6 The gasket assembly mechanism shown consists of three functional units: a gasket feeding and distributing unit 1, a gasket transfer unit 2, and a gasket positioning and secondary transfer unit 3, which work together to automatically assemble the gaskets.

[0018] Regarding gasket feeding and distribution unit 1: This unit is the starting point of the mechanism. The hopper is formed by four vertically arranged guide rods 102, creating an open-top space for storing stacked gaskets. A support plate 103 is fixed to the bottom of the hopper to secure the guide rods 102. Below the support plate 103, a gasket dispensing cylinder 101 is installed. The gasket dispensing cylinder 101 is a sliding cylinder with a material plate 101a mounted on its slide. The upper surface of the material plate 101a is in close contact with the bottom surface of the support plate 103, allowing it to slide horizontally. A material groove 101b matching the shape of a single gasket is provided on the material plate 101a.

[0019] The working process is as follows: Initially, the material trough 101b is located outside the hopper area. The gasket dispensing cylinder 101 actuates, driving the material plate 101a to move backward, causing the material trough 101b to move directly below the hopper. At this time, the bottommost gasket in the hopper will fall into the material trough 101b due to gravity. Subsequently, the gasket dispensing cylinder 101 moves, driving the material plate 101a and the material trough 101b carrying the single gasket out of the hopper area and to the designated picking position. This process uses a mechanical structure to force separation, and only one gasket can be transported out at a time, ensuring high reliability.

[0020] Regarding gasket transfer unit 2: This unit is responsible for transporting the separated gaskets from the sorting station to the positioning station. The horizontal movement module 203 uses a servo electric slide 203a, and a first lifting drive component 201 is fixed to its slide via a first mounting base 203b. The first lifting drive component 201 includes a first lifting cylinder 201a, whose piston rod points downwards and has a first fixing plate 201b mounted at its end. Four first vacuum suction cups 202 are evenly distributed on the first fixing plate 201b, which suck up the gaskets through vacuum negative pressure.

[0021] The working process is as follows: After the pad is transported to the picking position by the material plate 101a, the servo electric slide 203a drives the first lifting drive component 201 to move above that position. The first lifting cylinder 201a drives the first fixed plate 201b to descend, so that the four first vacuum suction cups 202 simultaneously contact and pick up the pad. Subsequently, the first lifting cylinder 201a rises, and the servo electric slide 203a drives the entire component to move above the pad positioning secondary transfer unit 3. The first lifting cylinder 201a descends again, the first vacuum suction cups 202 break the vacuum, and release the pad onto the platform of the positioning cylinder 301.

[0022] Regarding the secondary transfer unit 3 for gasket positioning: This unit is responsible for precisely positioning the gasket and finally assembling it onto the product. The positioning cylinder 301 is a bidirectional clamping cylinder, with two clamping rods 301a fixed to each of its two clamps for clamping and correcting the gasket's position from both sides. The unit also includes a second lifting drive component 302 and a lateral movement drive component 304. The second lifting drive component 302 includes a fixed base 302a, on which a lifting slide 302b is mounted via a guide rail slider pair. The lifting slide 302b is driven to rise and fall by a second cylinder 302c. Four second vacuum suction cups 303 are mounted on the bottom of the lifting slide 302b. The lateral movement drive component 304 includes a horizontal guide rail and a third cylinder 304a, which drives the entire second lifting drive component 302 to move laterally along the guide rail.

[0023] The working process is as follows: After the gasket is placed on the platform of the positioning cylinder 301 by the first vacuum suction cup 202, the positioning cylinder 301 actuates, driving the clamping rod 301a to clamp the gasket, centering it, and then releases it. Next, the lateral drive component 304 drives the second lifting drive component 302 to move above the positioning platform. The second cylinder 302c drives the lifting slide 302b to descend, causing the second vacuum suction cup 303 to contact and pick up the positioned gasket. Subsequently, the lifting slide 302b rises, and the lateral drive component 304 again drives the second lifting drive component 302 to move above the final product, such as the gearbox assembly station. Finally, the second cylinder 302c drives the lifting slide 302b to descend, the second vacuum suction cup 303 breaks the vacuum, and precisely places the gasket in the designated installation position of the product, completing the assembly.

[0024] In addition, the mechanism is equipped with a detection switch to monitor the amount of gaskets remaining in the hopper. When the amount is insufficient, an alarm is triggered to prompt manual addition of gaskets.

[0025] 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 and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
