Description

Technical Field

[0001] This utility model relates to the technical field of electronic price tag testing equipment, and in particular to a device for testing the pressure exerted during the installation of electronic price tags. Background Technology

[0002] As the digital transformation of the retail industry continues to deepen, electronic shelf labels have been widely used in various retail scenarios such as shopping malls, supermarkets, and convenience stores. Electronic shelf labels use wireless communication technology to achieve real-time, synchronized price updates, effectively improving operational efficiency, reducing the probability of human error, and laying the foundation for dynamic pricing and precision marketing.

[0003] Electronic shelf labels are typically secured to slots or holes in shelves using specific mounting bases. During installation, the operator aligns the clips on the back of the label with the mounting position on the side of the shelf and applies downward pressure perpendicular to the shelf plane until a "click" is heard, indicating the clips are fully locked in place. This installation method ensures that the label will not easily detach from daily bumps, vibrations, or customer touches, guaranteeing the stability and reliability of the information display.

[0004] Currently, the installation of electronic shelf labels mainly relies on manual operation. However, insufficient downward pressure during installation can lead to insecure installation, causing the labels to loosen and fall off during subsequent use, affecting normal operation and increasing maintenance costs. Excessive downward pressure, on the other hand, can damage internal components, crack the outer casing, or permanently damage the clip structure, directly resulting in product scrap. It also requires a certain level of strength from the installer. In the production and quality control stages, while manufacturers have a theoretical design value for the installation downward pressure, they lack efficient and reliable testing equipment to quantitatively test and verify each batch of products or newly designed installation structures. Traditional sampling inspection methods rely on the worker's feel, failing to provide objective and repeatable data support, making it difficult to effectively control product quality.

[0005] During the research and development phase, engineers need to repeatedly test and optimize the clip structure design of price tags. Without dedicated testing equipment, relying solely on manual testing and subjective judgment leads to long development cycles, unclear optimization directions, and increased time and manpower costs.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-4 As shown, this embodiment provides a basic electronic price tag installation pressure testing device, which includes a test platform 1, a position adjustment mechanism 4, and a pressure testing mechanism 5.

[0026] The test bench 1 is framed by aluminum profiles, with a base plate on top serving as the working surface, providing a stable mounting foundation for the entire device. Positioning pads 7 are provided on the top surface of the test bench 1 for quick and accurate placement of the test object and positioning of the transverse components. Function buttons 6 are installed on the side of the test bench 1 for controlling the start / stop of the device and setting parameters.

[0027] The position adjustment mechanism 4 is mounted on the test bench 1. In this embodiment, the mechanism is mainly a transverse movement component. The transverse movement component includes a high-precision servo-electric linear slide 3. A long slot 31 is formed on the top surface of the test bench 1, and the main body of the servo-electric linear slide 3 is fixedly mounted on the bottom surface of the test bench 1. A guide rail 32 is fixedly mounted on the top surface of the test bench 1, parallel to the long slot 31, and a slider 33 is slidably mounted on the guide rail 32. The bottom of the slider 33 passes downward through the long slot 31 via a connecting plate and is fixedly connected to the movable end of the servo-electric linear slide 3. Therefore, when the linear slide is working, it can drive the slider 33 to move precisely along the guide rail 32.

[0028] The downward pressure testing mechanism 5 is directly and fixedly mounted on the top surface of the slider 33. This mechanism includes a Z-axis lifting platform 51, a force gauge 52, a mounting strip 53, and a contact head 54. The force gauge 52 is fixed to the slider 33 via a mounting base. The mounting strip 53 is connected to the force-measuring end of the force gauge 52, and the contact head 54 is fixed to the bottom end of the mounting strip 53. The contact head 54 is preferably made of an elastic material such as silicone to avoid scratching the price tag surface.

[0029] The equipment also includes an electrical box 2, which is fixed below the test bench 1. The electrical box 2 integrates electrical components such as PLC, motor driver, and power module, forming the control system of the equipment.

[0030] Work process:

[0031] Preparation: Place the electronic price tag to be tested on the test table 1 according to the markings on the positioning sticker 7.

[0032] Positioning: By controlling the transverse component 3, the slider 33 and the entire downward pressure testing mechanism 5 are driven to move along the guide rail 32 until the contact head 54 is aligned with the predetermined pressing point of the price tag being tested.

[0033] Test execution: By rotating the turntable on top of the Z-axis lifting platform 51, the force gauge 52 is moved downwards, causing the contact head 54 to contact and press the price tag until it is installed in place with a "click". During this process, the force gauge 52 monitors and records the peak pressure in real time.

[0034] Reset: After the test is completed, the Z-axis lifting platform 51 is raised, and the transverse component 3 drives it back to the initial position.

[0035] This embodiment has a simple structure and low cost, and can achieve accurate measurement of downward pressure and automatic positioning in one direction, thus meeting the most basic testing requirements.

[0036] Example 2

[0037] like Figure 3 As shown, based on Embodiment 1, this embodiment enhances the functionality of the position adjustment mechanism 4 by adding lifting and angle adjustment capabilities, enabling it to adapt to electronic price tags of different specifications and installation angles, making it particularly suitable for research and development and precision quality inspection processes.

[0038] like Figure 2 and Figure 3 As shown, this embodiment has undergone the following important structural upgrades:

[0039] The position adjustment mechanism 4 retains the lateral movement component 3 while integrating a lifting component and an angle adjustment component at its movable end.

[0040] The lifting assembly includes a horizontal sliding base plate 41 fixed to the top surface of the slider 33. Two mounting plates 42 are symmetrically fixed to the horizontal sliding base plate 41, and each mounting plate 42 is equipped with a motor-driven lead screw slide 43. The slide plates 44 of the two lead screw slides 43 are connected by a rigid mounting bracket 45 to achieve synchronous movement. By driving the lead screw slides 43, the vertical position of the mounting bracket 45 and all its components can be precisely adjusted.

[0041] The angle adjustment assembly includes a support plate 46 hinged to the mounting bracket 45. At least one electrically operated telescopic rod 47 (such as an electric push rod or servo cylinder) has its cylinder end hinged to the mounting bracket 45, and its push rod end hinged to the center of the support plate 46. By precisely controlling the extension and retraction of the telescopic rod 47, the support plate 46 can be driven to rotate around the hinge axis, thereby enabling continuous and precise fine-tuning of the pressing angle of the pressure testing mechanism 5 to simulate the installation conditions of a tilted shelf.

[0042] The downward pressure testing mechanism 5 is fixedly installed on the top surface of the support plate 46 by bolts. In addition, a limiting block 48 is fixedly installed on the top surface of the support plate 46, and its side is in close contact with the base of the Z-axis lifting platform 51, which effectively prevents the Z-axis lifting platform 51 from moving horizontally during the test, ensuring the stability and repeatability of the test.

[0043] Work process:

[0044] Preparation and rough positioning: After placing the price tag, the contact head 54 is initially positioned above the pressing point by the horizontal movement component 3 and the lifting component.

[0045] Angle and height fine-tuning: If the price tag mounting surface is tilted, adjust the angle of the support plate 46 using the angle adjustment component to ensure that the movement trajectory of the contact head 54 is strictly perpendicular to the mounting surface. Simultaneously, set a suitable pressing start point using the Z-axis lifting platform 51.

[0046] Test execution: The Z-axis lifting platform 51 drives the force gauge 52 to move downward to complete the pressing test.

[0047] This embodiment, by introducing lifting and angle adjustment components, greatly improves the adaptability and testing accuracy of the equipment, and can provide highly reliable data support for product design and quality control.
