Description

Technical Field

[0001] This utility model relates to a transfer mechanism, and more particularly to a bumper transfer mechanism that integrates flipping, lifting, and weighing. Background Technology

[0002] Car bumpers are typically manufactured using injection molding technology. During this process, some manufacturing plants choose to install the injection molding equipment at a higher position to make more efficient use of limited space. This means that after the bumper is injection molded, a specialized transfer mechanism is needed to safely and smoothly move it from a higher position to a lower position for subsequent processing and handling. However, currently, there are no dedicated transfer devices on the market specifically designed for moving injection-molded bumpers from higher to lower positions. Furthermore, most existing transfer devices only have basic transportation functions, are relatively simple, and cannot meet diverse production needs, thus limiting production efficiency and flexibility to some extent. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a bumper transfer mechanism that integrates flipping, lifting, and weighing. This mechanism is specifically designed to transfer the injection-molded bumper from a high place to a low place, and integrates the flipping component, lifting component, and weighing component into one unit. It can sequentially perform flipping, lifting, conveying, and weighing operations on the bumper, and can meet diverse production needs.

[0004] The technical solution to the above technical problem is: a bumper transfer mechanism that integrates flipping, lifting and weighing, including a main frame, a flipping component, a lifting component and a weighing component, wherein the main frame includes a longitudinal support frame and a transverse support frame connected to the lower end of the longitudinal support frame.

[0005] The flipping assembly includes a flipping motor, a flipping shaft, a flipping plate, and a clamp for gripping the bumper. The flipping motor is mounted on the top of the longitudinal support frame, the flipping shaft is mounted on the top of the longitudinal support frame via a bearing and a bearing seat, one end of the flipping plate is connected to the flipping shaft, the flipping shaft is connected to the rotating shaft of the flipping motor, and the clamp is mounted on the other end of the flipping plate.

[0006] The lifting assembly includes a lifting motor, a lifting frame, a lead screw, and a lifting block. The lead screw is movably mounted on a longitudinal support frame, and a lifting nut is installed on the lead screw. The lifting nut is connected to the lifting block, and the lifting block is connected to the lifting frame.

[0007] The weighing component is a floating scale, which includes a weighing frame. When the lifting frame of the lifting component is at its lowest point, the upper surface of the lifting frame is lower than the upper surface of the weighing frame.

[0008] Furthermore, the floating scale also includes four pressure sensors arranged in a rectangle on a horizontal support frame. Each pressure sensor is equipped with an elastic support, and the weighing frame is placed on the elastic support.

[0009] Furthermore, the floating scale also includes four limit seats to prevent damage to the pressure sensor, which are mounted on the transverse support frame and located above the pressure sensor.

[0010] Furthermore, the lifting frame includes a mounting plate and two support frames. The mounting plate is provided with two transverse slides, and the two support frames are respectively mounted on the transverse slides via transverse sliders.

[0011] Furthermore, guide rails are provided on both sides of the longitudinal support frame on both sides of the lifting block, and lifting sliders are movably installed on the guide rails. The lifting sliders are connected to the mounting plate of the lifting frame through I-shaped connecting blocks.

[0012] Furthermore, the elastic support includes a lower fixed block and an upper floating block, with a spring between the lower fixed block and the upper floating block. The lower floating block is mounted on a pressure sensor, and the top of the upper floating block has an installation groove in which a ball bearing is movably installed. The lower end face of the weighing frame has an elongated groove, and the ball bearing at the top of the upper floating block is located in the elongated groove of the weighing frame.

[0013] Furthermore, it also includes a PLC control system for controlling the start and stop of the tilting motor and the lifting motor.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This invention is a transfer mechanism specifically designed for transporting injection-molded bumpers from a high position to a low position. It integrates a flipping component, a lifting component, and a weighing component into one unit, enabling sequential flipping, lifting, conveying, and weighing of the bumper. The flipping component allows the bumper to be directly removed from the rear mold after injection molding and placed onto it, achieving the flipping of the bumper without the more complex method of removing it from the front mold. The weighing component measures the weight of the molded bumper to determine its injection molding quality, providing a reference for subsequent processing. This invention integrates flipping, weighing, and bumper conveying functions into one unit, meeting diverse production needs.

[0016] 2. This utility model uses a floating scale as the weighing component. The floating scale employs four pressure sensors arranged in a rectangle on a horizontal support frame. This rectangular arrangement of the four pressure sensors provides more stable support for the weighing frame. Furthermore, the top of the elastic support component uses ball bearings that engage with the elongated groove of the weighing frame, further ensuring the stability of the weighing frame. Compared to ordinary scales, this floating scale reduces the requirements for the placement of the product. As long as the product is placed on the weighing frame, regardless of whether it is balanced, the floating scale can accurately read the value. It has the advantages of being convenient to use, easy to operate, accurate in reading, and automatically calibrated.

[0017] 3. The lifting frame of the lifting assembly of this utility model is installed on the guide rail with an I-shaped connecting block. Compared with the traditional square connecting plate, this structure can save some materials and reduce the weight of the overall structure. During the sliding process, the lifting mechanism is not easy to slip.

[0018] 4. The lifting frame of this utility model consists of a mounting plate and two support frames that slide on the mounting plate. The two support frames can slide relative to each other on the mounting plate to adjust their support positions. They can be adjusted according to the shape and size of the bumper to be supported, making them more convenient and flexible to use.

[0033] P-Bumper. Detailed Implementation

[0034] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0035] Example 1: A bumper transfer mechanism that integrates flipping, lifting, and weighing, such as... Figures 1-4 As shown, it includes a main frame 1, a flipping assembly 2, a lifting assembly 3, and a weighing assembly 4. The main frame 1 includes a longitudinal support frame 11 and a transverse support frame 12 connected to the lower end of the longitudinal support frame. An outer baffle 13 is also installed on the outside of the main frame 1, and a weight display 401 is provided on the outer baffle.

[0036] The flipping assembly 2 includes a flipping motor 21, a flipping shaft 22, a flipping plate 23, and a clamp 25 for gripping the bumper. The clamp is selected based on the bumper to be clamped and includes a suction cup. The clamp is existing technology, and its specific structure will not be described in detail. The flipping motor 21 is mounted on the top of the longitudinal support frame 11. The flipping shaft 22 is mounted on the top of the longitudinal support frame 11 via a bearing and a bearing seat 24. One end of the flipping plate 23 is connected to the flipping shaft 22, and the flipping shaft 22 is connected to the rotating shaft of the flipping motor 21. The clamp 25 is mounted on the other end of the flipping plate 23 via a quick-connect coupling or other detachable means.

[0037] The lifting assembly 3 includes a lifting motor 31, a lifting frame 32, a lead screw (not shown in the figure), and a lifting block 33. The lead screw is movably mounted on a longitudinal support frame, and a lifting nut (not shown in the figure) is installed on the lead screw. The lifting block 33 is U-shaped, with the open end defined as the front end and the other end defined as the rear end. The lifting nut is connected to the rear end of the lifting block, and the front end of the lifting block 33 is connected to the lifting frame 32. A longitudinal baffle 35 is also provided on the longitudinal support frame 11. The longitudinal baffle 35 is located inside the U-shaped lifting block 33, which is equivalent to the U-shaped lifting block 33 being fitted onto the longitudinal baffle 35.

[0038] The weighing component is a floating scale, which includes a weighing frame 41. When the lifting frame 32 of the lifting component is at its lowest point, the upper surface of the lifting frame is lower than the upper surface of the weighing frame 41. At this time, the bumper on the lifting frame is supported by the weighing frame 41 for weighing.

[0039] In this embodiment, the floating scale further includes four pressure sensors 42, which are rectangularly arranged on the transverse support frame 12. Each pressure sensor is equipped with an elastic support member 43, which includes a lower fixed block 431 and an upper floating block 432. The lower floating block has an upper protruding rod, and the lower end of the upper fixed block has an inner slide rail. The upper protruding rod of the lower floating block is located within the inner slide rail of the lower fixed block, and a spring 434 is provided between the upper protruding rod and the inner slide rail. The position between the lower fixed block and the upper floating block can change. The lower floating block 431 is mounted on the pressure sensor 42, and the top of the upper floating block 432 has a mounting groove in which a ball bearing 433 is movably mounted. The lower end face of the weighing frame has an elongated groove, and the ball bearing at the top of the upper floating block is located within the elongated groove of the weighing frame 41. The floating scale also includes four limiting seats 44 to prevent damage to the pressure sensors. The limiting seats 44 are mounted on the transverse support frame and located above the pressure sensors 42. During normal weighing, the weighing frame 41 does not contact the limit seat 44. When the weight of the bumper is too great, the weighing frame is pressed down to the limit seat, and the weighing frame is supported by the limit seat 44, which can prevent the pressure sensor 42 from being damaged due to the weight of the bumper.

[0040] In this embodiment, the lifting frame 32 includes a mounting plate 321 and two support frames 322. The mounting plate 321 is provided with two transverse slide rails 323, and the two support frames are respectively mounted on the transverse slide rails 323 via transverse sliders 324. Guide rails 34 are also provided on both sides of the longitudinal support frames on both sides of the lifting block. Lifting sliders 37 are movably mounted on the guide rails, and the lifting sliders are connected to the mounting plate 321 of the lifting frame via I-shaped connecting blocks 36.

[0041] In this embodiment, a PLC control system 7 is also included to control the start and stop of the tilting motor and the lifting motor. A position sensor 6 is installed on the transverse support frame via a support plate to detect whether the bumper has been lowered onto the weighing frame. When the position sensor 6 detects the bumper, it transmits a signal to the PLC control system to stop the lifting motor. A magnetic switch 5 is installed at the top of the longitudinal support frame to detect whether the tilting plate 23 has tilted to the correct position and transmits the information to the PLC control system to control the tilting motor.

[0042] Working Process: This utility model is used in conjunction with a picking robot. Initially, the lifting frame 32 is at its highest point. The picking robot picks up the injection-molded bumper from the mold and places it onto the clamp 25. The clamp holds the bumper, and the flip motor 21 rotates the clamp 180°, placing the bumper onto the lifting frame. The lifting motor then drives the lifting frame to descend at a constant speed. When the lifting frame reaches its lowest point, the bumper is positioned on the weighing frame 41. The weighing frame presses down on the pressure sensor 42 to weigh the product, and the weight display 401 accurately shows the weight of the product. When the worker removes the bumper and the pressure on the floating scale disappears, a signal is sent to the PLC control system. The PLC control system then controls the lifting frame to return to its original position, awaiting the next action.
