Description

Technical Field

[0001] This utility model relates to the technical field of automotive logo product manufacturing equipment, specifically to a mistake-proof forming device for automotive combination characters. Background Technology

[0002] In the automotive lettering decal industry, composite characters are widely used identification elements, and their demand in the automotive market continues to grow. These characters are typically made of metal and undergo surface treatments such as electroplating to make them conductive. Furthermore, a specific paint film pattern is formed on the character areas of the composite character surface through a dotting process. This paint film has good insulating (non-conductive) properties, thus creating a physical structure on the composite character where conductive and non-conductive areas coexist.

[0003] However, with current technology, the layout of letter car stickers largely relies on manual placement of individual letters in a preset order. For composite characters, although the composite characters themselves have shape characteristics, the device cavity does not have a dedicated constraint structure designed for the direction of the composite characters. It only relies on the basic outline to complete the formation of the composite characters, which makes it very easy for the composite characters to be placed in reverse during the production process. This type of design cannot limit the correct orientation of the composite characters from the production source. Therefore, after production, the character orientation must be manually verified one by one. This not only increases labor costs, but may also cause reversed products to flow into the downstream process due to human fatigue or operational negligence, which will lead to the labeling error during subsequent pasting and ultimately reduce the reliability of the product. Utility Model Content

[0004] In view of the defects in the existing technology, the purpose of this utility model is to provide a mistake-proof forming device for automotive combination characters, so as to solve the problems of low production efficiency and high product orientation error rate caused by human negligence due to reliance on manual verification.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A mistake-proofing molding device for automotive composite characters, comprising: The base has a mounting cavity for accommodating the combined characters, and at least two through holes at the bottom that communicate with the mounting cavity; A battery assembly, located on one side of the substrate, has a positive electrode unit and a negative electrode unit; The conductive element includes a first conductive element and a second conductive element, which are respectively disposed in the two through holes; one end of the first conductive element is electrically connected to the positive electrode unit of the battery assembly, and the other end extends to the bottom of the mounting cavity; one end of the second conductive element is electrically connected to the negative electrode unit of the battery assembly, and the other end extends to the bottom of the mounting cavity. A display device is electrically connected to the battery assembly; The first and second conductive elements are positioned at the bottom of the mounting cavity to match the conductive area of ​​the combined character to be inspected. When the combined character is correctly positioned in the mounting cavity, the conductive area of ​​the combined character can simultaneously contact the first and second conductive elements, thereby forming a closed loop with the battery assembly, the display device, and the conductive elements connected via the conductive area of ​​the combined character, triggering the display device to operate.

[0006] By adopting the above technical solution, an electrical detection circuit consisting of a battery module, conductive components, and a display device is integrated into the device, and the position of the detection contact is matched with the conductive area of ​​the combined character. This allows the device to automatically determine the direction of the combined character. The circuit will only be turned on and the display device will be triggered when the combined character is placed in the only correct direction. The operator does not need to carefully identify the direction of the combined character when placing it. The operator can complete the operation simply by following the real-time feedback from the display device (such as light on / off). This greatly shortens the operation time, improves the overall efficiency of the typesetting operation, and fundamentally replaces the subjective verification method that relies on human eye recognition. It also eliminates the reverse product outflow caused by human fatigue or negligence.

[0007] Furthermore, the conductive element is provided with a fixing part and an abutting part for abutting the combined characters; the fixing part is inserted into the through hole, and its lower end is used for electrically connecting the positive or negative electrode unit of the battery assembly; the abutting part is connected to the upper end of the fixing part and exposed at the bottom of the mounting cavity.

[0008] By adopting the above technical solution: the cooperation between the fixing part and the perforation ensures the stable installation and reliable electrical connection of the conductive component on the substrate, preventing detection failure due to loosening or displacement; the abutting part, as a dedicated functional end that contacts the combined characters, is exposed at the bottom of the mounting cavity and directly forms electrical contact with the conductive area of ​​the combined characters. This structure ensures the stability and reliability of the electrical contact.

[0009] Furthermore, the end of the abutment portion is hemispherical.

[0010] By adopting the above technical solution: by designing the contact part in a hemispherical shape, the hemispherical contact can better adapt to the slight unevenness or assembly tolerance that may exist in the combined characters, avoiding poor contact or circuit interruption caused by unevenness of the combined character plane. The hemispherical surface wears more evenly, which helps to extend the service life of key contact parts of conductive components, thereby improving the overall reliability and durability of the device.

[0011] Furthermore, the line connecting the contact portions of the first conductive element and the second conductive element at the bottom of the mounting cavity is parallel to or forms a preset angle α with the central axis of the mounting cavity, wherein 0 degrees < α ≤ 35 degrees.

[0012] By adopting the above technical solution, the geometric positional relationship between the line connecting the two abutting parts and the central axis of the mounting cavity is clearly defined. The included angle α is preset to 0° or within a small angle range of 0° to 35°, so that the arrangement of the two abutting parts is highly consistent with the conductive area of ​​most asymmetrical combined characters. This angle range design ensures that the conductive area of ​​the combined characters can accurately cover the two detection points only when the combined characters are placed in the preset direction. It also avoids deviation from the effective conductive area due to excessive angle, significantly improving the accuracy and reliability of direction judgment.

[0013] Furthermore, the distance between the two abutting portions matches the boundary distance between the conductive and non-conductive areas on the combined character.

[0014] By employing the above technical solution, and precisely matching the distance between the two contact points to the critical boundary dimension between the conductive and non-conductive areas of the combined character, this device can accurately identify subtle positional differences caused by incorrect orientation of the combined character. Specifically, when the combined character is placed in the correct orientation, this distance ensures that both contact points fall completely and reliably within the conductive area, thereby achieving stable circuit conduction. Conversely, if the combined character is reversed or rotated, at least one contact point will inevitably fall into the non-conductive area, resulting in a reliable circuit disconnection.

[0015] Furthermore, the display device is an LED indicator light, and the substrate has a lamp hole corresponding to the position of the LED indicator light, and the LED indicator light is installed in the lamp hole.

[0016] By adopting the above technical solution, the indicator device is specifically designed as an LED indicator light, and a dedicated lamp hole is opened on the substrate for installation. The lamp hole provides a stable installation position for the LED indicator light, preventing it from loosening or shifting during use. The LED indicator light has the characteristics of low power consumption, fast response, high brightness and long life. Its light signal can be quickly and clearly captured by the operator, realizing instant, intuitive and low-energy status feedback.

[0017] Furthermore, the center of the mounting position of the display device, the geometric center of the mounting cavity, and the center of the battery assembly are located on the same vertical axis, and the display device is disposed between the mounting cavity and the battery assembly.

[0018] By adopting the above technical solution, the display device is positioned between the mounting cavity and the battery assembly, with the centers of all three located on the same vertical line. This layout allows the operator's line of sight to naturally shift downwards to the centrally located display device when performing character assembly and placement operations while looking directly at the mounting cavity, resulting in an extremely intuitive and efficient observation path. Simultaneously, the linear arrangement in the vertical direction provides the shortest and most regular path for wire connections, improving the reliability of electrical connections.

[0019] Furthermore, the substrate has multiple sub-cavities for accommodating a single character on the side near the mounting cavity, and the multiple sub-cavities are arranged sequentially along the length of the mounting cavity.

[0020] By adopting the above technical solution, multiple sub-cavities for accommodating individual characters are integrated on the substrate and arranged sequentially along the length of the mounting cavity, a multi-functional integrated device is formed. The two key processes of combining characters and orderly arranging individual characters are integrated into the same workstation. The operator can complete the task without moving between multiple tools or areas, which greatly improves the continuity and overall efficiency of the typesetting operation. The arrangement of multiple sub-cavities along the length of the mounting cavity provides the operator with a clear and intuitive guide to the order of picking and placing, effectively avoiding the omission or incorrect order of individual characters, and further ensuring the splicing accuracy of the final product.

[0021] Furthermore, the battery assembly is electrically connected to the first conductive element and the second conductive element via wires; a wiring groove for accommodating the wires is provided at the bottom of the substrate, and the wiring groove corresponds to the position of the through hole.

[0022] By adopting the above technical solution, a wiring groove corresponding to the perforation position is opened at the bottom of the substrate to accommodate the connecting wire. The wiring groove provides a dedicated channel for the wire, avoiding the wire from hanging messily outside the substrate or being loosened or damaged due to external pulling, thereby improving the reliability of the electrical connection and effectively avoiding the safety hazards that may be caused by messy wires.

[0023] Furthermore, the mounting cavity is in the shape of a long rectangular strip, and its four inner corners are provided with rounded chamfers or beveled chamfers.

[0024] By adopting the above technical solution, rounded or beveled chamfers are provided at the four inner corners of the mounting cavity. The rectangular cavity shape is highly compatible with the outline of most composite characters, providing a stable and accurate accommodating space. The rounded or beveled chamfers at the four inner corners firstly serve a guiding function, facilitating the smooth insertion of composite characters and reducing placement difficulties or jamming caused by misalignment. Secondly, the rounded or beveled chamfer structure effectively eliminates sharp inner corners, preventing damage to the edges of the composite characters during insertion and removal, protecting the product and extending the service life of the mold itself. Furthermore, the rounded or beveled chamfers are easier to clean and maintain, preventing dust accumulation.

[0025] The beneficial effects of this utility model are as follows: 1. By integrating an electrical contact detection circuit onto the substrate, the orientation of the combined characters is converted into a clear electrical signal for judgment. When the character is placed in the correct orientation, the circuit automatically conducts and triggers an intuitive light prompt, completely replacing the traditional verification method that relies on human eye recognition and subjective judgment. This not only eliminates the possibility of reversed products flowing out due to human fatigue or negligence, ensuring product accuracy, but also shortens the verification time per transaction, significantly improving typesetting production efficiency and reliability. 2. By precisely centering the display device, mounting cavity, and battery assembly on the same vertical axis, the battery assembly, display device, and mounting cavity are logically distributed from top to bottom. During operation, the user's movements and line of sight naturally move vertically along this axis: the hand places the combined characters from below, and the eyes look upward to see the LED indicator status, eliminating the need for any lateral searching or posture adjustments. Combined with the sequential arrangement of sub-cavities on the sides, the entire typesetting operation forms a clear linear workflow, significantly improving the accuracy, speed, and comfort of operation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 , Figure 2 As shown, this embodiment provides an error-proof forming device for automotive combination characters. This device is mainly used in the production or layout process of automotive letter stickers to automatically verify whether the placement direction of the combination characters 500 is correct, thereby preventing product errors caused by the reverse placement of the combination characters 500 from the source. The device mainly includes: a base 10 as the mounting and supporting foundation; a battery assembly 20 that provides working power; a conductive component 40 for electrical detection; and a display device 30 that provides status feedback.

[0032] Reference Figure 2 As shown, the base 10, serving as the mounting foundation for the entire device, is made of metal or engineering plastic. The base 10 has a mounting cavity 101 for accommodating the combined character 500. This mounting cavity 101 is a long rectangle, and the four inner corners of the mounting cavity 101 are all machined with rounded or beveled chamfers to facilitate the guidance when the combined character 500 is placed in and to prevent damage. On the side of the base 10 near the mounting cavity 101, there are also multiple sub-cavities 102 for accommodating individual characters. The multiple sub-cavities 102 are arranged sequentially along the length of the mounting cavity 101. The shape of each sub-cavity 102 matches the outline of an independent single character (such as an English letter) for orderly placement of individual characters during typesetting.

[0033] The battery assembly 20 is a power module fixed on the outer wall of the base 10, and the upper surface of the battery assembly 20 is flush with the top plane of the base 10. The battery assembly 20 has a positive electrode unit 201 and a negative electrode unit 202 for powering the entire detection circuit.

[0034] Reference Figure 3 As shown, the conductive element 40 includes a first conductive element 401 and a second conductive element 402; the substrate 10 has two through holes 103 that communicate with the mounting cavity 101. The first conductive element 401 and the second conductive element 402 are respectively disposed in the two through holes 103. One end of the first conductive element 401 is electrically connected to the positive electrode unit 201 of the battery assembly 20, and the other end extends to the bottom of the mounting cavity 101; one end of the second conductive element 402 is electrically connected to the negative electrode unit 202 of the battery assembly 20, and the other end extends to the bottom of the mounting cavity 101.

[0035] Reference Figure 4 As shown, the specific battery assembly 20 is electrically connected to the first conductive element 401 and the second conductive element 402 via wires; a wiring groove 105 for accommodating wires is provided at the bottom of the base 10, and the wiring groove 105 corresponds to the position of the through hole 103. The wiring groove 105 prevents the wires from hanging messily outside the base 10 or from being loosened or damaged due to external pulling.

[0036] Reference Figures 1 to 5 As shown, each conductive element 40 is provided with a fixing part 411 and an abutting part 412 for contacting the combined character 500; the fixing part 411 is rod-shaped and passes through the through hole 103, its lower end is used for electrical connection to the positive electrode unit 201 or negative electrode unit 202 of the battery assembly 20, and its upper end is connected to the abutting part 412; the abutting part 412 is connected to the upper end of the fixing part 411 and exposed at the bottom of the mounting cavity 101, and the end of the abutting part 412 is preferably processed into a hemispherical shape to provide stable point contact; the line direction connecting the abutting parts 412 of the first conductive element 401 and the second conductive element 402 at the bottom of the mounting cavity 101 is parallel to the center of the mounting cavity 101. The axes are parallel or at a preset angle α, where 0 degrees < α ≤ 35 degrees. The central axis X of the mounting cavity 101 and the line L connecting the abutment portions 412 of the first conductive member 401 and the second conductive member 402 at the bottom of the mounting cavity 101 are preset to 0 degrees or within a small angle range of 0 to 35 degrees. This ensures that the arrangement of the two abutment portions 412 closely matches the conductive area 501 of most asymmetrical combined characters 500. This angle range design ensures that the conductive area 501 of the combined characters 500 can accurately cover the two abutment portions 412 only when the combined characters 500 are placed in the preset direction; it also avoids deviation from the effective conductive area 501 due to excessive angle.

[0037] The distance between the two abutment portions 412 matches the boundary distance between the conductive area 501 and the non-conductive area 502 on the combined character 500. By precisely corresponding the spacing of the two abutment portions 412 to the critical boundary dimension between the conductive area 501 and the non-conductive area 502 of the combined character 500, this device can accurately identify subtle positional differences caused by incorrect orientation of the combined character 500. Specifically, when the combined character 500 is placed in the correct orientation, this spacing ensures that the two abutment portions 412 can fall completely and reliably within the conductive area 501, thereby achieving stable circuit conduction. Conversely, if the combined character 500 is reversed or rotated, at least one abutment portion 412 will inevitably fall into the non-conductive area 502, resulting in a reliable circuit disconnection.

[0038] Refer to 2. Figure 4 As shown, the display device 30, in this embodiment, is an LED indicator light. The LED indicator light features low power consumption, fast response, high brightness, and long lifespan, and its light signal can be quickly and clearly captured by the operator. A lamp hole 104 is provided on the substrate 10 corresponding to the position of the LED indicator light. The LED indicator light is installed in the lamp hole 104, which provides a stable mounting position for the LED indicator light, preventing loosening or displacement during use. Its pins are connected to the circuit of the battery assembly 20 via wires.

[0039] Reference Figure 2 As shown, the center of the installation position of the display device 30, the geometric center of the mounting cavity 101, and the center of the battery assembly 20 are located on the same vertical axis, and the centers of the three are located on the same vertical axis Y. This layout allows the operator's line of sight to naturally move down to the display device 30 located in the middle when performing the operation of picking up and placing the combined characters 500 while looking directly at the mounting cavity 101, making the feedback observation path extremely intuitive; and the display device 30 is located between the mounting cavity 101 and the battery assembly 20.

[0040] Reference Figure 1 As shown, the composite character 500 is made of a metal substrate and undergoes electroplating to form a conductive area 501. Then, through a precision coating process, an insulating varnish film is applied to the character on the conductive area 501, while the character itself constitutes a non-conductive area 502. Therefore, the composite character 500 exhibits a specific electrical structure with a conductive area 501 and a non-conductive area 502.

[0041] Reference Figures 1 to 5As shown, this device consists of a circuit formed by the battery assembly 20, the first conductive element 401, the second conductive element 402, and an LED indicator connected in series. The on / off state of this circuit is directly controlled by the combined character 500 placed in the mounting cavity 101. When the operator places the combined character 500 into the mounting cavity 101 in the correct orientation, the conductive area 501 of the combined character 500 simultaneously covers and reliably contacts the two hemispherical abutment portions 412. At this time, the current forms a complete path: flowing out from the positive terminal unit 201 of the battery assembly 20, through the first conductive element 401, the conductive area 501 of the combined character 500, and the second conductive element 402, and finally flowing through the display device 30 and returning to the negative terminal unit 202 of the battery assembly 20. When the circuit is on, the display device 30 lights up or flashes, sending a clear and immediate "correct" visual signal to the operator.

[0042] If the composite character 500 is placed in reverse or rotated, due to the asymmetry of the conductive area 501 of the composite character 500, at least one contact portion 412 will be opposite to the non-conductive area 502 of the composite character 500. This causes the circuit to be broken at any point, preventing the formation of a closed circuit. With the circuit broken, the indicator light on the display device 30 remains off, clearly indicating to the operator that the current orientation is incorrect and the orientation of the composite character 500 needs to be adjusted. By converting the conductive area 501 and non-conductive area 502 of the product into detectable electrical signals and comparing them using preset precise geometric relationships, automated and highly reliable error prevention of the orientation of the composite character 500 during the production process is achieved.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
