Description

Technical Field

[0001] This utility model relates to the technical field of automotive switch marking production equipment, specifically to a disc hot stamping machine. Background Technology

[0002] Emergency stop indicator signs in automobiles are typically made with prominent colors and patterns so that drivers can quickly identify and operate them in emergency situations. During production, the patterned signs, made of plastic or rubber sheets, need to be heat-pressed onto the surface of a felt board. This process is currently mainly done manually, but manually heat-pressed signs have the following problems: inaccurate heat-pressing time and poor uniformity of operation among different workers may cause the patterned signs to not adhere firmly to the felt board, resulting in them falling off; excessively high heat-pressing temperatures can cause the felt to scorch or the plastic or rubber sheets to deform, affecting their appearance and performance; most importantly, manual heat-pressing may cause the patterned signs to shift in position, and production efficiency is low. Summary of the Invention

[0003] The purpose of this invention is to overcome the technical problems of poor temperature and time control and low efficiency when manually heating car switch markings.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A rotary hot stamping machine, comprising:

[0006] A rotating disc is provided, with a housing below it. A servo motor is installed inside the housing, and the output end of the servo motor is connected to the center of the rotating disc. Multiple hot stamping stations are arranged in a circular array on the upper surface of the rotating disc, and each hot stamping station is equipped with a mounting base.

[0007] The hot stamping mechanism is equipped with a fixed frame, and the fixed frame is connected to a hot stamping template through a first servo electric cylinder. The hot stamping template faces at least one hot stamping station.

[0008] The servo motor and the first servo cylinder are electrically connected to the industrial control board. The industrial control board controls the servo motor to drive the rotating disk to rotate sequentially to different workstations to perform different processes.

[0009] Furthermore, the mounting brackets are set in pairs, with each pair of mounting brackets adapted to the left and right indicator symbols respectively.

[0010] Furthermore, a spring-loaded feeding mechanism is provided on one side of the rotating disc. This mechanism includes a material box containing a spring-loaded rod. A pattern identifier is vertically stacked on the top surface of the spring-loaded rod. An opening allowing the pattern identifier to enter and exit is provided on the top surface of the material box. A first lateral movement device is mounted opposite the opening via a fixed frame. This first lateral movement device is connected to a second servo cylinder, which in turn is connected to a vacuum suction cup for transferring the pattern identifier. The vacuum suction cup is connected to a first air pump, which is electrically connected to the industrial control board. The industrial control board controls the lateral movement device to first move the vacuum suction cup above the material box. After the second servo cylinder lowers its height, the air pump sucks up the material. Once sucking up the material, the second servo cylinder raises its height, and the lateral movement device moves to the hot stamping station for material feeding. The second servo cylinder then lowers its height again and releases the vacuum suction cup, completing the placement of the pattern identifier onto the felt board.

[0011] Furthermore, the first lateral movement device is also connected to a positioning mechanism, which includes a third servo electric cylinder positioned directly opposite the mounting base via a fixed frame. The third servo electric cylinder has a positioning ring floating on a pneumatic rod. The positioning ring has a bevel angle adapted to the outer circumference of the felt plate. Similar to a vacuum suction cup, the positioning ring matches the shape of the felt plate. The positioning ring is positioned by moving up and down through the third servo electric cylinder to fit the outer circumference of the felt plate. The elasticity of the pneumatic rod prevents excessive pressure from being applied to the felt plate.

[0012] Furthermore, a discharging mechanism is also provided on the side of the rotating disc opposite to the feeding mechanism, and the hot stamping mechanism is located between the spring-loaded feeding mechanism and the discharging mechanism; the discharging mechanism includes a second transverse movement device, the end of which is connected to a cylinder gripper, which is connected to a second air pump, and the second transverse movement device and the second air pump are electrically connected to the industrial control board, and a discharge port is provided below the discharging mechanism. The second transverse movement device moves the cylinder gripper to clamp the indicator sign indicating that the processing is complete and then discharges the material through the discharge port.

[0013] Furthermore, the first lateral movement device and / or the second lateral movement device includes a servo slide rail arranged laterally and a slide block slidably arranged on the servo slide rail. The slide block is fixedly equipped with a vacuum suction cup and / or a cylinder gripper. The first lateral movement device and / or the second lateral movement device are electrically connected to the industrial control board.

[0014] Furthermore, there are two adjacent discharge ports, corresponding to the left and right indicator signs respectively. The two discharge ports are separated by a partition, and each port passes through the box and extends out a downwardly inclined lip plate.

[0015] Furthermore, an industrial camera is installed at the top of the feed inlet. The industrial camera is electrically connected to a monitor, which is mounted on the top surface inside the frame. The industrial camera and monitor are electrically connected to the industrial control board. The industrial camera is used to detect whether the product meets standards, and simultaneously takes photos or videos, feeding the results back to the monitor. Preferably, the industrial camera can also be connected to an alarm to alert the operator of any defective products.

[0016] Furthermore, a waste outlet is provided, which is located near the feed inlet along the second transverse movement device. The waste outlet passes through the box body and extends out to form a downwardly inclined lip plate. The second transverse movement device controls product output while also screening waste.

[0017] Furthermore, a frame is installed above the rotating disc, and the frame is encased in a protective shell. The protective shell has an operating window, and safety light curtains are installed on both sides of the operating window. These safety light curtains are electrically connected to the industrial control board. When the operator's hand or other objects enter the hazardous area, they will be detected by the safety light curtains, and the equipment will immediately stop operating, thus preventing accidents.

[0018] Furthermore, a touch screen is also provided, with the industrial control board electrically connected to the touch screen, and casters are also provided at the bottom of the enclosure.

[0019] The advantages and beneficial effects of this utility model are as follows:

[0020] 1. By integrating advanced servo motors, servo cylinders, and industrial control boards, a fully automated process is achieved from material loading to hot stamping and unloading. This automation not only significantly improves production efficiency but also reduces manual intervention and the possibility of human error.

[0021] 2. Utilizing a servo system and precision mechanical structure, the equipment achieves high-precision hot stamping and pattern / marking placement. In particular, the design of the third servo electric cylinder and positioning ring ensures accurate positioning of the felt board during the hot stamping process, further improving product quality and consistency.

[0022] 3. With the addition of a touch screen and monitor, the equipment can be easily operated and the production process can be monitored. Attached Figure Description

[0038] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model. Example

[0039] A rotary hot stamping machine, equipped with:

[0040] A rotating disc 10 is provided, with a housing 11 located below it. A servo motor is installed inside the housing 11, and the output of the servo motor is connected to the center of the rotating disc 10. Four hot stamping stations 12 are arranged in a circular array on the upper surface of the rotating disc 10. The rotating disc rotates counterclockwise, and is used for installation, feeding, hot stamping, and unloading in sequence. The hot stamping stations 12 are arranged in pairs and are equipped with mounting bases 13 for left and right sides respectively.

[0041] The magazine-type feeding mechanism includes a material box 21, inside which a spring push rod 22 is installed. A pattern mark is vertically stacked on the top surface of the spring push rod 22. An opening 22 is provided on the top surface of the material box 21 to allow the pattern mark to enter and exit. A first transverse movement device 23 is also provided opposite the opening via a fixed frame. The first transverse movement device 23 is connected to a second servo cylinder. The second servo cylinder is connected to a vacuum suction cup 24 for transferring the pattern mark. The vacuum suction cup 24 is connected to a first air pump. The industrial control board controls the first transverse movement device 12 to first move the vacuum suction cup 24 above the material box 21. After the second servo cylinder lowers the height, it adjusts the first air pump to suck up the material. After completion, the second servo cylinder raises the height, and the first transverse movement device 23 moves to the hot stamping station 12 for feeding. The second servo cylinder lowers the height again and releases the vacuum suction cup 24 to complete the placement of the pattern mark onto the felt board.

[0042] The positioning mechanism 30 is connected to the first transverse movement device 23. It includes a third servo electric cylinder positioned directly opposite the mounting base via a fixed frame. The third servo electric cylinder has a positioning ring 32 floatingly mounted via a pneumatic rod 31. The positioning ring 32 has a bevel angle adapted to the outer circumference shape of the felt plate. Similar to the movement process of the vacuum suction cup 24, the positioning ring 32 matches the shape of the felt plate. The up-and-down movement of the third servo electric cylinder causes the positioning ring 32 to fit against the outer circumference of the felt plate to complete the positioning. The elasticity of the pneumatic rod 31 prevents excessive pressure from being applied to the felt plate.

[0043] The hot stamping mechanism 40 includes a fixed frame, and the fixed frame is connected to a hot stamping template 41 via a first servo electric cylinder. The hot stamping template 41 is facing a hot stamping station.

[0044] The unloading mechanism 50 includes a second transverse moving device 51, the end of which is connected to a cylinder gripper 52. The cylinder gripper 52 is connected to a second air pump. A unloading port 53 is provided below the unloading mechanism 50. The second transverse moving device 51 moves the cylinder gripper 52 to clamp the completed indicator and discharge it into the unloading port 53. The unloading port 53 is divided into two adjacent ports by a partition, corresponding to the left and right indicators respectively. It passes through the housing 11 and extends out a downwardly inclined lip plate 54.

[0045] The inspection unit 60 includes an industrial camera 61 mounted on top of the discharge port 53. The industrial camera 61 is electrically connected to a display 62. The industrial camera 61 is used to inspect whether the product meets the standards, and simultaneously takes photos or records videos, feeding the results back to the display 62 for display. Preferably, the industrial camera can also be connected to an alarm to alert the operator of the presence of defective products.

[0046] The screening mechanism includes a waste outlet 71, which is located near the discharge outlet 53 along the second transverse movement device 51. The waste outlet 71 passes through the housing 11 and extends out to a downwardly inclined lip plate 54. The second transverse movement device controls the product discharge while also transferring the waste material.

[0047] The safety mechanism includes a frame 81 surrounding the rotating disk 10 above the housing 11. A display 62 is mounted on the top surface inside the frame 81. The frame 81 is enclosed by a protective shell 82, which has an operating window 83. Safety light curtains 84 are installed on both sides of the operating window 83 and are electrically connected to the industrial control board. When the operator's hand or other objects enter the hazardous area, they will be detected by the safety light curtains, and the equipment will immediately stop operating, thereby preventing accidents.

[0048] The top surface of the housing 11 is also equipped with a touch screen 90, and casters 91 are also provided at the bottom of the housing. Specifically, the first and second transverse movement devices include a horizontally arranged servo slide rail 92 and a slide block 93 slidably arranged on the servo slide rail 92. The vacuum suction cup 24 and the cylinder gripper 52 are respectively fixed on the slide blocks 93 of the first and second transverse movement devices. The servo slide rail 92 can be composed of a servo motor and a lead screw guide rail.

[0049] The following components are connected to the industrial control board via circuitry: first and second air pumps; servo slide rails 92 for the first transverse movement device 23 and the second transverse movement device 51; servo motors, first, second, and third servo electric cylinders; industrial camera 61; display 62; safety light curtain 84; and touch screen 90.

[0050] Working principle:

[0051] First, the felt board is placed from the operating window to the installation station. Then, the drive motor rotates 90° counterclockwise to transfer the felt board to the feeding mechanism. The positioning mechanism moves towards the hot stamping station via the first lateral movement device. Simultaneously, the vacuum suction cup of the spring-loaded feeding mechanism picks up the pattern mark from the material box, and then moves it to the feeding position on the rotating disc via the first lateral movement device and the second servo cylinder. The pattern mark is pre-pressed onto the felt board to form a preliminary product, and then reset. The servo motor rotates 90° counterclockwise again to transfer the preliminary product to the hot stamping station. The first servo cylinder of the hot stamping mechanism drives the hot stamping template to hot stamp the pattern mark on the felt board to form the product, and then resets. The servo motor rotates 90° counterclockwise again to feed the product into the unloading position. First, an industrial camera takes a picture to determine the hot stamping position error. If it is within 1mm, it is considered a finished product. The picture result is displayed on the monitor. The cylinder grippers of the unloading mechanism clamp the finished product, and then the second lateral movement device moves it to the unloading port, releasing the grippers for discharge. If the error is too large or the pattern markings do not correspond to the felt board, the second transverse movement device will move a greater distance to send the defective product into the waste inlet. The discharge port and waste inlet can be connected to a separate container to collect finished and defective products.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
