Description

Technical Field

[0001] This utility model relates to the field of printing technology, and in particular to a control panel printing device based on thermoelectric devices. Background Technology

[0002] The control panel of a thermoelectric device is the core of human-machine interaction and the central hub of device operation, undertaking three core functions: "command input, status feedback, and safety control." It directly determines the ease of use, temperature control accuracy, and operational safety of the thermoelectric device. Different buttons or knobs have different operating instructions, which are easily identified by operators through printed text and labels.

[0003] However, existing printing equipment based on screen printing technology mostly adopts a single-station design for printing. It requires a full set of operations such as workpiece positioning, screen alignment, squeegee printing, and screen detachment before unloading and loading new workpieces. Among these, non-printing operations are time-consuming and lack flexibility for small-batch production. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a control panel printing device based on thermoelectric devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a control panel printing device based on thermoelectric devices, comprising an operating table, a controller, a screen frame, and a mounting bracket. The screen frame is fixedly installed between two sets of mounting brackets. A printing mechanism is arranged directly above the screen frame, and a dual-station mechanism is arranged directly below the screen frame. The dual-station mechanism includes a base, a first support seat, a carrier frame, and a second support seat. The two sets of bases are fixedly installed on the upper side of the operating table. The first support seat and the second support seat are arranged vertically and slidably connected to the middle of the two sets of bases via guide rails. A positioning groove for placing the control panel is opened in the middle of the carrier frame. The two sets of carrier frames are fixedly installed on the upper sides of the first support seat and the second support seat respectively by bolts.

[0006] Preferably, the printing mechanism includes a connecting frame, a pressing assembly, a front scraper, and a rubber scraper, wherein the front scraper and the rubber scraper are in a parallel position and are respectively installed at the lower ends of two sets of pressing assemblies.

[0007] Preferably, the pressing assembly includes a cylinder, a sliding plate, and a mounting base. The cylinder is fixedly mounted through the end of the connecting frame, and the sliding plate is fixedly mounted on the lower part of the cylinder's movable rod.

[0008] Preferably, the slide plate is slidably connected to the inside of the end of the connecting frame via a guide rail, and the front scraper and the rubber scraper are respectively fixedly installed on the lower side of the two sets of mounting seats.

[0009] Preferably, a lifting mechanism is fixedly installed on the upper side of the operating platform, and a transverse mechanism is fixedly connected to the other side of the lifting mechanism. The lifting mechanism and the transverse mechanism operate in the same way. The transverse mechanism includes a servo motor, a belt drive assembly, a long frame, and a moving seat. The connecting frame is fixedly connected to one side of the moving seat, and the moving seat is slidably connected to the inner wall of the long frame via a guide rail.

[0010] Preferably, the two sets of synchronous pulleys of the belt drive assembly are rotatably installed inside the long frame, one side of the synchronous belt of the belt drive assembly is fixedly connected to the back side of the moving seat, and the servo motor is fixedly installed at the end of the long frame and is drivenly connected to one of the synchronous pulleys in the belt drive assembly.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the dual-station mechanism features an upper and lower arranged first and second carrier seats, coupled with a base guide rail, enabling alternating sliding of the carrier seats. This saves on intermediate non-printing operations, improves printing efficiency, and allows the detachable carrier frame to accommodate different sizes via positioning grooves and bolts. This significantly enhances the device's adaptability to control panels of different thermoelectric components, reducing changeover costs. The printing mechanism's pressing assembly, through the linkage of a cylinder, slide plate, and mounting base, ensures that the front scraper and rubber scraper press down precisely and in parallel. The former combs out the dye, while the latter evenly squeezes out the ink, effectively improving printing clarity and uniformity.

[0012] 2. In this utility model, the transverse mechanism adopts a servo motor, belt drive assembly and moving seat in combination. The servo motor has precise speed control and the belt drive assembly has zero slippage transmission, which drives the printing mechanism to move precisely along the long frame guide rail, avoiding printing position deviation and adapting to the high precision requirements of thermoelectric device control panel. The lifting mechanism has the same operating principle as the transverse mechanism and can synchronously adjust the height of the screen frame and the printing mechanism, which can not only ensure the fit between the screen frame and the panel, but also leave operating space when switching between two workstations, thus improving safety.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a control panel printing device based on thermoelectric devices, including an operating table 1, a controller 2, a screen printing frame 4, and a mounting bracket 5. The screen printing frame 4 is fixedly installed between two sets of mounting brackets 5. A printing mechanism 8 is arranged directly above the screen printing frame 4, and a dual-station mechanism 3 is arranged directly below the screen printing frame 4. The dual-station mechanism 3 includes a base 31, a first support 32, a carrier frame 33, and a second support 34. The two sets of bases 31 are fixedly installed on the upper side of the operating table 1. The first support 32 and the second support 34 are arranged vertically and slidably connected to the middle of the two sets of bases 31 via guide rails. A positioning groove for placing the control panel is opened in the middle of the carrier frame 33. The frame 33 is fixedly installed on the upper side of the first support seat 32 and the second support seat 34 by bolts. The printing mechanism 8 includes a connecting frame 81, a pressing assembly 82, a front scraper 83 and a rubber scraper 84. The front scraper 83 and the rubber scraper 84 are in a parallel state and are respectively installed at the lower end of the two sets of pressing assemblies 82. The pressing assembly 82 includes a cylinder 821, a slide plate 822 and a mounting seat 823. The cylinder 821 is fixedly installed through the end of the connecting frame 81. The slide plate 822 is fixedly installed at the lower part of the movable rod of the cylinder 821. The slide plate 822 is slidably connected to the inside of the end of the connecting frame 81 through a guide rail. The front scraper 83 and the rubber scraper 84 are respectively fixedly installed on the lower side of the two sets of mounting seats 823.

[0018] The specific settings and functions of this embodiment are described below: The operating table 1 serves as the supporting foundation for the entire device. Its flat surface provides a stable mounting reference for components such as the dual-station mechanism 3 and the mounting bracket 5, preventing printing offset caused by base wobbling and ensuring the overall stability of the printing process. The controller 2 is connected to all electrical components in the device. Two sets of mounting brackets 5 are symmetrically fixed and support the screen frame 4, keeping the screen frame 4 horizontal and positioned precisely between the printing mechanism 8 and the dual-station mechanism 3. This setup ensures that the screen frame 4 can accurately cover the control panel on the support base below, while also providing a stable framework for dye carrying and extrusion, making it the core carrier for printing pattern transfer.

[0019] Two sets of bases 31 are fixed parallel to each other on the upper side of the operating table 1. The guide rails pre-set on their tops provide sliding tracks for the first support base 32 and the second support base 34. This setting not only restricts the movement direction of the support bases, ensuring that they only move towards / away from the screen frame 4 in the horizontal direction, but also reduces sliding friction, making the switching of the support bases smoother. The first support base 32 and the second support base 34 adopt a "vertical arrangement + guide rail sliding" setting. On the one hand, it avoids spatial conflict between the two support bases in the horizontal direction and maximizes the use of the vertical space of the operating table 1. On the other hand, the two can move independently along the guide rails of the base 31, and can realize the alternating action of entering and exiting the printing station, providing structural support for continuous operation of dual stations. A positioning slot adapted to the control panel is provided in the middle and fixed to the upper side of the two carrier seats by bolts. The core functions of this setting are twofold: first, the positioning slot can accurately limit the position of the control panel to prevent the panel from shifting during the printing process and causing the pattern to be misaligned; second, the detachable structure fixed by bolts allows for flexible replacement of carrier frames 33 with different positioning slot specifications according to the size of the control panel corresponding to the thermoelectric device, thereby improving the adaptability of the device to different models of products and reducing equipment replacement costs.

[0020] The pressing assembly 82 consists of a cylinder 821, a sliding plate 822, and a mounting base 823, which together form a "power-transmission-execution" linkage structure: the cylinder 821 is fixed through and fixed to the end of the connecting frame 81, and its movable rod can provide a stable up and down driving force; the sliding plate 822 is fixed to the lower part of the movable rod of the cylinder 821 and is slidably connected to the inside of the connecting frame 81 through a guide rail. This setting can limit the movement direction of the sliding plate 822 and prevent the cylinder driving force from deviating, causing the scraper to tilt; the mounting base 823 serves as the connection medium between the scraper and the sliding plate 822, and the front scraper 83 and the rubber scraper 84 are fixed by bolts, which facilitates the replacement and maintenance of the scraper. The front squeegee 83 and the rubber squeegee 84 are arranged in parallel and installed at the lower ends of the two sets of pressing components 82 respectively. The two work together: the front squeegee 83 can first sort and flatten the dye on the screen frame 4 to avoid dye accumulation; the rubber squeegee 84, with its elasticity, will evenly squeeze the dye through the mesh of the screen frame 4 and transfer it to the control panel surface during the subsequent pressing process, ensuring the clarity and uniformity of the printed pattern. The parallel arrangement structure ensures that the two can cover the same printing area when moving horizontally, avoiding the pattern from being broken.

[0021] Example 2: Figure 1 - Figure 2 As shown, a lifting mechanism 7 is fixedly installed on the upper side of the operating platform 1, and a transverse mechanism 6 is fixedly connected to the other side of the lifting mechanism 7. The lifting mechanism 7 and the transverse mechanism 6 operate in the same way. The transverse mechanism 6 includes a servo motor 61, a belt drive assembly 62, a long frame 63, and a moving seat 64. A connecting frame 81 is fixedly connected to one side of the moving seat 64. The moving seat 64 is slidably connected to the inner wall of the long frame 63 via a guide rail. Two sets of synchronous pulleys of the belt drive assembly 62 are rotatably installed inside the long frame 63. One side of the synchronous belt of the belt drive assembly 62 is fixedly connected to the back side of the moving seat 64. The servo motor 61 is fixedly installed at the end of the long frame 63 and is connected to one of the synchronous pulleys of the belt drive assembly 62.

[0022] The overall effect of this embodiment is that the transverse mechanism 6 adopts a transmission structure of "servo motor 61 - belt drive assembly 62 - moving seat 64": the servo motor 61 has high-precision speed control capability, and its output power can be accurately transmitted to the belt drive assembly 62; the two sets of synchronous pulleys of the belt drive assembly 62 are rotatably installed inside the long frame 63, and the synchronous belt is fixedly connected to the back of the moving seat 64. This transmission method can convert the rotational motion of the servo motor 61 into the horizontal linear motion of the moving seat 64, and the synchronous belt drive has the characteristics of smooth transmission and no slippage, which can ensure that when the moving seat 64 drives the printing mechanism 8 to move along the guide rail of the long frame 63, it accurately reaches the initial printing position or the designated printing area, avoiding misalignment of the printed pattern due to movement deviation, and significantly improving the accuracy of the printing position.

[0023] The lifting mechanism 7 operates in the same way as the transverse mechanism 6. The lifting mechanism 7 is fixed on one side of the operating table 1 and the transverse mechanism 6 is fixedly connected on the other side. This structure can adjust the height of the transverse mechanism 6, the printing mechanism 8 and the screen frame 4 simultaneously by moving the lifting mechanism 7 up and down. Before printing, the lifting mechanism 7 can be adjusted according to the thickness of the control panel so that the screen frame 4 accurately covers the upper side of the control panel. This ensures the fit between the screen and the panel to ensure the printing effect, while avoiding excessive pressure that could damage the panel or screen. When switching between two workstations, if the second support seat 34 needs to be pulled out after printing and the first support seat 32 needs to be pushed in, the lifting mechanism 7 can raise the screen frame 4 and the printing mechanism 8 a certain distance to leave enough space for the horizontal sliding of the support seat, avoid collisions between components, and improve the safety and smoothness of operation.

[0024] The usage and working principle of this device are as follows: During use, different positioning slots are opened in the middle of the carrier frame 33 according to the type of thermoelectric device and the size of the control panel. The carrier frame 33 is bolted to the first support seat 32 and the second support seat 34. Multiple control panels are first embedded in the positioning slots of the carrier frame 33 where the second support seat 34 is located. By pushing the second support seat 34, it slides along the guide rail between the two sets of bases 31 to the very end of the base 31. At this time, the second support seat 34 and its control panel are located below the screen frame 4. The servo motor 61 is started, injecting power into the belt drive assembly 62 to make it run in the long frame 63. The synchronous belt of the belt drive assembly 62 applies a horizontal force to the fixed moving seat 64, causing it to move inside the long frame 63 via the guide rail, thereby driving the printing mechanism 8 to move to the initial printing position. The lifting mechanism 7 and the transverse mechanism 6 operate on the same principle. The transverse mechanism 6 and the screen frame 4 are controlled... The lifting and lowering of the printing mechanism 8 causes the screen frame 4 to cover the upper side of the control panel. Then, the two sets of cylinders 821 are activated in sequence. The movable rod of the cylinder 821 extends downward, pushing the slide plate 822 down at the end of the connecting frame 81, thereby pushing the mounting seat 823 downward. The front scraper 83 and the rubber scraper 84 are pressed down in sequence. With the cooperation of the horizontal movement of the transverse mechanism 6, the front scraper 83 and the rubber scraper 84 press down in sequence, squeezing the dye in the screen frame 4 onto the control panel. After the control panel on the second carrier 34 is printed, the lifting mechanism 7 rises a certain distance and places the next batch of control panels in the positioning groove of the carrier frame 33 where the first carrier 32 is located. The first carrier 32 is pushed directly under the second carrier 34, and the second carrier 34 is pulled out. The same method is used to print again. During the printing process, the previous batch of printed control panels is operated on. This cycle is repeated to save intermediate non-printing operations and improve printing efficiency.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
