Description

Technical Field

[0001] This utility model belongs to the field of screen testing technology, and in particular relates to testing equipment and vehicle display production line. Background Technology

[0002] With the continuous improvement of automotive intelligence, in-vehicle displays, as a core component of human-machine interaction, directly impact driving experience and safety. During the production process, in-vehicle displays require calibration of multiple optical and electrical parameters, among which Vcom (Common Voltage) and white balance calibration are particularly critical. Vcom calibration eliminates flicker and ensures voltage stability; white balance calibration ensures accurate color reproduction and avoids color cast. These two calibration operations must be performed at specific testing stations using precision instruments, placing strict requirements on the display's positioning accuracy, testing environment stability, and work cycle time.

[0003] In the current production and testing of automotive displays, testing typically relies on manual or semi-automated methods. Operators need to manually place the display on a specific position on the test bench and align and connect it with the test structure. Frequent manual loading, unloading, and alignment operations severely restrict the efficiency of the entire testing process, making it difficult to meet the high-speed requirements of large-scale automotive display production. Furthermore, traditional test benches lack effective positioning structures, making them prone to displacement, shaking, or even tipping during transport or testing due to inertia or vibration. This instability in position can lead to poor contact between the test structure and the display interface, causing test interruptions or inaccurate test results. Utility Model Content

[0004] The purpose of this application is to provide a testing device and an in-vehicle display production line, aiming to solve the problem of how to improve testing efficiency and reliability.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, a testing device is provided, comprising a material transfer station and a testing station along a first direction. The testing device includes: a first carrier slidably disposed along the first direction, the first carrier including a base, an adsorption structure disposed on the base, and limiting blocks disposed on the base; the adsorption structure supporting and adsorbing material; and a plurality of limiting blocks arranged at intervals around the adsorption structure, the plurality of limiting blocks forming a limiting area for limiting the material; a driving structure for driving the first carrier to reciprocate between the material transfer station and the testing station; and a testing mechanism disposed at the testing station; wherein the first carrier receives the material to be tested at the material transfer station and transfers the material to the testing station; the testing mechanism tests the material; and the first carrier transfers the tested material to the material transfer station for unloading.

[0007] In some embodiments, the adsorption structure includes suction cups for adsorbing the material, wherein a plurality of suction cups are arranged at intervals and the plurality of suction cups together support the material.

[0008] In some embodiments, the first carrier further includes a sensing structure disposed on the base, the sensing structure being located within the limiting area, the sensing structure being used to detect whether the material is located within the limiting area.

[0009] In some embodiments, the testing apparatus further includes a second carrier for carrying the material and sliding along the first direction. The driving structure is used to drive the second carrier to reciprocate between the transfer station and the testing station. The first carrier or the second carrier receives the material to be tested at the transfer station and transfers the material to the testing mechanism. The driving structure is also used to drive the second carrier to rise and fall, so that the second carrier has a first position and a second position, the height of the second position being greater than the height of the first position. When the second carrier is in the first position, the second carrier slides below the first carrier. When the second carrier is in the second position, the second carrier receives the material at the transfer station.

[0010] In some embodiments, the driving structure includes a sliding drive member and a lifting assembly connected to the sliding drive member. The sliding drive member is used to drive the first carrier and the lifting assembly to slide back and forth between the material transfer station and the testing station. The second carrier is connected to the lifting assembly, and the lifting assembly is used to drive the second carrier to lift.

[0011] In some embodiments, the sliding drive includes a first driver and a second driver located below the first driver, the first vehicle and the lifting assembly are respectively connected to the first driver and the second driver, and the first driver and the second driver are respectively used to drive the first vehicle and the lifting assembly to slide.

[0012] In some embodiments, the material is a display screen, and the first carrier further includes a test box and a backlight control box disposed on the base. The test box and the backlight control box are communicatively connected to the display screen. The test box is used to drive the display screen to display images, and the backlight control box is used to adjust the backlight of the display screen.

[0013] In some embodiments, the base includes a housing with a cavity and a support plate rotatably connected to the housing. The cavity has an opening at the top of the housing. The support plate is used to open or close the opening. The adsorption structure and the limiting block are disposed on the support plate. The test box and the backlight control box are disposed in the cavity. The support plate has a through hole communicating with the cavity. The test box and the backlight control box are communicatively connected to the display screen through the through hole.

[0014] In some embodiments, the testing mechanism includes a linear motion structure and a test piece connected to the linear motion structure. The linear motion structure is used to drive the test piece to move in three-dimensional space, and the test piece is used to detect the material.

[0015] Secondly, a production line for an in-vehicle display screen is provided, including the aforementioned testing device.

[0016] The testing device provided in this application automatically drives the first carrier to slide back and forth between the material transfer station and the testing station through a drive structure, realizing the automatic transfer and testing of the vehicle-mounted display screen. Operators or robotic arms only need to perform loading and unloading operations at a fixed material transfer station, which greatly improves the degree of automation, thereby significantly increasing the overall production cycle and improving testing efficiency. Furthermore, the first carrier limits the material through multiple limit blocks, effectively restricting the movement of the material in all directions in the horizontal plane. Combined with the adsorption structure's adsorption effect on the material, it ensures that the material's posture remains stable throughout the entire transfer and testing process, thereby improving the reliability of the test.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0031] Please see Figure 1 and Figure 2This application provides a testing device with a material transfer station 200 and a testing station 300 along a first direction. The testing device includes a first carrier 10, which is slidably disposed along the first direction. The first carrier 10 includes a base 11, an adsorption structure 12 disposed on the base 11, and limiting blocks 13 disposed on the base 11. The adsorption structure 12 is used to support and adsorb material 400. Multiple limiting blocks 13 are arranged at intervals around the adsorption structure 12, and the multiple limiting blocks 13 surround to limit the material. The system includes a limiting area of ​​400; a driving structure 30 for driving the first carrier 10 to slide back and forth between the transfer station 200 and the testing station 300; and a testing mechanism 40 disposed at the testing station 300. The first carrier 10 receives the material 400 to be tested at the transfer station 200 and transfers the material 400 to the testing station 300. The testing mechanism 40 tests the material 400. The first carrier 10 transfers the tested material 400 to the transfer station 200 for unloading.

[0032] It should be noted that the material 400 provided in this embodiment is an in-vehicle display screen. As a core component of human-computer interaction, the display performance of the in-vehicle display screen directly affects the driving experience and driving safety. The test station 300 is equipped with a test mechanism 40, which can perform multiple optical and electrical parameter calibrations on the in-vehicle display screen, such as Vcom and white balance calibration. Of course, in other possible embodiments, the material 400 can also be other structures, and this application does not limit the specific structure of the material 400.

[0033] Understandably, the material transfer station 200 can be connected to a transfer trolley or robotic arm, or it can be manually loaded. When the first carrier 10 moves to the material transfer station 200, the robotic arm loads material 400 onto the first carrier 10. After the material 400 on the first carrier 10 has been tested, the first carrier 10 slides to the material transfer station 200, where the robotic arm can unload the tested material 400. In other words, the material transfer station 200 can both load and unload material 400, thus allowing operators to simultaneously monitor both loading and unloading statuses.

[0034] The testing device provided in this application automatically drives the first carrier 10 to slide back and forth between the material transfer station 200 and the testing station 300 by setting a drive structure 30, realizing the automatic transfer and testing of the vehicle display screen. Operators or robots only need to perform loading and unloading operations at the fixed material transfer station 200, which greatly improves the degree of automation, thereby significantly increasing the overall production cycle and improving testing efficiency. In addition, the first carrier 10 limits the material 400 by multiple limit blocks 13, effectively restricting the movement of the material 400 in all directions in the horizontal plane. Combined with the adsorption effect of the adsorption structure 12 on the material 400, it ensures that the posture of the material 400 remains stable throughout the entire transfer and testing process, thereby improving the reliability of the test.

[0035] In some embodiments, such as Figure 2 As shown, the adsorption structure 12 includes suction cups 121 for adsorbing material 400. Multiple suction cups 121 are arranged at intervals, and the multiple suction cups 121 together support the material 400. By using multiple suction cups 121 arranged at intervals, the vacuum adsorption force can be evenly distributed to multiple key support points of the material 400. This arrangement avoids the problems that may be caused by uneven adsorption force between the center and the edge when using a single large suction cup 121, and also avoids local stress concentration caused by too few support points.

[0036] In some embodiments, the first carrier 10 further includes a sensing structure 14 disposed on the base 11. The sensing structure 14 is located within the limiting area and is used to detect whether the material 400 is within the limiting area. The sensing structure 14 can detect in real time whether the material 400 is present within the limiting area. Only when the sensing structure 14 confirms that the material 400 has been correctly placed in the limiting area will the control system allow subsequent actions, such as initiating vacuum adsorption and allowing the drive structure 30 to drive sliding or activating the test mechanism 40. This effectively avoids the equipment executing an invalid test process when the material 400 is not in place or is improperly placed, thus avoiding wasting energy and occupying production cycle time. Optionally, the sensing structure 14 is a photoelectric sensor or a proximity switch.

[0037] Optionally, the shape of the limiting block 13 is adapted to the outer contour shape of the material 400, that is, the limiting block 13 is a contour-following limiting block 13, so that it can better fit the surface of the material 400 and further improve the limiting effect on the material 400.

[0038] In some embodiments, such as Figure 3 and Figure 4As shown, the testing device also includes a second carrier 20 for carrying material 400 and sliding along a first direction. A drive structure 30 is used to drive the second carrier 20 to slide back and forth between the transfer station 200 and the testing station 300. The first carrier 10 or the second carrier 20 receives the material 400 to be tested at the transfer station 200 and transfers the material 400 to the testing mechanism 40. The drive structure 30 is also used to drive the second carrier 20 to rise and fall, so that the second carrier 20 has a first position and a second position. The height of the second position is greater than the height of the first position. When the second carrier 20 is in the first position, the second carrier 20 slides below the first carrier 10. When the second carrier 20 is in the second position, the second carrier 20 receives the material 400 at the transfer station 200.

[0039] In this embodiment, the drive structure 30 is used to drive the second carrier 20 to rise and fall, so the second carrier 20 can switch between a first position and a second position, with the height of the second position being greater than the height of the first position. Optionally, if the height of the first position is less than the height of the first carrier 10, then when the second carrier 20 is in the first position, the second carrier 20 is located below the first carrier 10, so that the running path of the second carrier 20 can be offset from the running path of the first carrier 10 in the vertical direction. Therefore, the sliding of the second carrier 20 will not affect the sliding of the first carrier 10. The height of the second position can be flush with the height of the first carrier 10. Therefore, when the first carrier 10 and the second carrier 20 are in the material transfer station 200, the receiving positions of the first carrier 10 and the second carrier 20 are the same, which facilitates material loading. By accurately raising the second carrier 20 to a fixed second position that matches the preset working height of the loading equipment (such as a robot), a stable working plane is created for material loading. This avoids the need for the loading equipment to change the loading height, simplifies the loading procedure, and significantly reduces the risk of collisions, falls, or positioning deviations during the loading process.

[0040] Furthermore, the second carrier 20 is raised and lowered via the drive structure 30, cleverly utilizing vertical space to allow it to switch between the first and second positions. In the sliding state, the second carrier 20 slides hidden beneath the first carrier 10, significantly saving horizontal installation space and avoiding the increased footprint caused by using dual parallel tracks. The entire device has a compact and rational structural layout, achieving dual-station functionality within a limited space and reducing equipment manufacturing costs.

[0041] In some embodiments, the drive structure 30 includes a sliding drive member 31 and a lifting assembly 32 connected to the sliding drive member 31. The sliding drive member 31 drives the first carrier 10 and the lifting assembly 32 to reciprocate between the material transfer station 200 and the testing station 300. The second carrier 20 is connected to the lifting assembly 32, and the lifting assembly 32 drives the second carrier 20 to move up and down. Understandably, the sliding drive member 31 can serve as a unified power source, driving the first carrier 10 and the entire lifting assembly 32 and the second carrier 20 to perform high-precision linear reciprocating sliding, ensuring the synchronicity and path consistency of the two carriers' horizontal movement. The lifting assembly 32 specifically controls the vertical movement of the second carrier 20, enabling it to precisely switch between a first position and a second position.

[0042] In some embodiments, the sliding drive 31 includes a first drive 311 and a second drive 312 located below the first drive 311. The first carrier 10 and the lifting assembly 32 are respectively connected to the first drive 311 and the second drive 312. The first drive 311 and the second drive 312 are used to drive the first carrier 10 and the lifting assembly 32 to slide. By setting the first drive 311 and the second drive 312 arranged at intervals in the vertical direction, that is, by using the drive in a layered arrangement, the vertical space can be efficiently utilized in the vertical direction, avoiding the waste of space in the width direction caused by setting two sets of sliding tracks side by side for the first carrier 10 and the second carrier 20, making the equipment layout more compact. At the same time, the first drive 311 and the second drive 312 directly drive their target objects, with the shortest transmission path, low energy loss, and high driving efficiency.

[0043] In some embodiments, the first driver 311 includes a first electric guide rail 3111 extending along a first direction, with two first electric guide rails 3111 spaced apart. The second driver 312 includes a second electric guide rail 3121 extending along the first direction, with two second electric guide rails 3121 spaced apart. The two ends of the first carrier 10 are slidably connected to the two first electric guide rails 3111, and the two ends of the lifting assembly 32 are slidably connected to the two second electric guide rails 3121. Since the vehicle-mounted display screen has a certain width, its weight and installation position may generate a large overturning moment. The dual-guide rail structure can effectively resist these moments, completely preventing the first carrier 10 and the second carrier 20 from experiencing jamming, shaking, or swaying during high-speed start-up, stopping, or lifting. This ensures that the first carrier 10 and the second carrier 20 are subjected to uniform force and maintain a stable posture throughout the sliding process. This is crucial for testing and calibration, as any slight vibration or deformation will cause a change in the relative position between the test structure and the display screen, directly guaranteeing the accuracy and repeatability of the test data.

[0044] In some embodiments, such as Figure 4 and Figure 5 As shown, the lifting assembly 32 includes a connecting plate 321 slidably connected to the sliding drive member 31, a lifting driver 322 connected to the connecting plate 321, and a support plate 323 connected to the lifting driver 322. The support plate 323 supports the second carrier 20, and the lifting driver 322 drives the support plate 323 to rise or fall. Optionally, the lifting driver 322 can be a cylinder, which can use the compression and expansion of gas to achieve linear motion, thereby driving the support plate 323 to rise or fall.

[0045] In some embodiments, the lifting assembly 32 further includes a guide structure 324 connected between the connecting plate 321 and the support plate 323. The guide structure 324 guides the support plate 323 to move vertically, and multiple guide structures 324 are arranged at intervals along the periphery of the connecting plate 321. The guide structure 324 includes a guide sleeve 3241 connected to the connecting plate 321 and a guide post 3242 that slides through the guide sleeve 3241 vertically. The top end of the guide post 3242 is connected to the support plate 323. By setting the guide structure 324, it is ensured that the movement of the support plate 323 is strictly vertical, ensuring high movement accuracy. Furthermore, the multiple guide structures 324 arranged at intervals along the periphery of the connecting plate 321 can effectively prevent the support plate 323 from tilting, twisting, or swaying during the lifting process, greatly improving the stability and reliability of the lifting movement.

[0046] In some embodiments, the lifting assembly 32 further includes a limiting plate 325 located at the lower end of the connecting plate 321 and a lifting buffer 326 connected to the limiting plate 325 on the side facing the connecting plate 321. The limiting plate 325 is connected to the end of the guide post 3242 away from the support plate 323. The lifting buffer 326 is used to abut against the connecting plate 321 when the limiting plate 325 moves to a preset height, so as to limit the movement stroke of the support plate 323.

[0047] By incorporating a lifting buffer 326, excessive movement of the limit plate 325, guide post 3242, and support plate 323 is effectively prevented, thus avoiding the risk of the limit plate 325 or support plate 323 colliding with other mechanisms and protecting the expensive drive and precision mechanical structure from damage. Furthermore, at the last moment before the limit plate 325 contacts the connecting plate 321, the lifting buffer 326 contacts and activates first. Through hydraulic damping or elastic deformation, it efficiently absorbs the upward kinetic energy of the limit plate 325, thereby converting the violent rigid impact and improving the overall operational stability, reliability, and service life of the equipment. Optionally, the lifting buffer 326 is a hydraulic buffer.

[0048] In some embodiments, the connecting plate 321 is provided with a buffer 327 on the side facing the support plate 323. The buffer 327 is located on the moving path of the support plate 323 and is used to buffer the impact of the support plate 323. The buffer 327 can effectively absorb the inertial kinetic energy of the descending support plate 323, transforming the violent rigid collision into a soft and controllable stop, preventing the support plate 323, the connecting plate 321, and the precision components mounted thereon from deforming, loosening, or being damaged due to the impact, significantly improving the durability and reliability of the equipment. At the same time, it also avoids the transmission of impact vibration to the vehicle display screen, providing a more stable environment for precision testing. Optionally, the buffer 327 is a buffer pad made of flexible materials such as rubber, silicone, or sponge.

[0049] In some embodiments, such as Figure 2 As shown, material 400 is a display screen. The first carrier 10 also includes a test box 15 and a backlight control box 16 disposed on the base 11. The test box 15 and the backlight control box 16 are communicatively connected to the display screen. The test box 15 is used to drive the display screen to display images, and the backlight control box 16 is used to adjust the backlight of the display screen. Optionally, the test box 15 is a PG test box 15. The function of the PG test box 15 is to provide various standard or specific test image signals for the vehicle display screen. When the display screen is disconnected from the vehicle system, the PG test box 15 simulates a standard video signal source, allowing the display screen to work independently and display images. The backlight control box 16 can precisely control the backlight brightness level for measuring the performance of the display screen under different brightness levels.

[0050] In some embodiments, the base 11 includes a housing 111 having a accommodating cavity 112 and a support plate 113 rotatably connected to the housing 111. The accommodating cavity 112 forms an opening at the top of the housing 111. The support plate 113 is used to open or close the opening. An adsorption structure 12 and a limiting block 13 are disposed on the support plate 113. A test box 15 and a backlight control box 16 are disposed in the accommodating cavity 112. The support plate 113 has a through hole 1131 communicating with the accommodating cavity 112. The test box 15 and the backlight control box 16 are communicatively connected to the display screen through the through hole 1131.

[0051] By integrating the test box 15 and backlight control box 16 into the accommodating cavity 112 of the housing 111, the testing device is integrated into a compact unit, resulting in a cleaner and more compact equipment layout. This is particularly suitable for use in space-constrained automated production lines or high-density testing stations. Furthermore, the cables connecting the test box 15, backlight control box 16, and the display screen can be directly and shortly routed through the through-holes 1131 on the carrier plate 113, avoiding lengthy external wiring. The housing 111 protects the test box 15 and backlight control box 16, offering multiple advantages, such as preventing dust and debris from the production environment from falling into the interfaces and causing poor contact. The carrier plate 113, as an independent mounting platform, can be customized with a dedicated adsorption structure 12 and limiting block 13 for different models of automotive displays, while the test box 15 and backlight control box 16 within the accommodating cavity 112 remain unchanged.

[0052] Optionally, a cooling fan 17 is installed inside the accommodating cavity 112. Since the test box 15 and the backlight control box 16 will continuously generate heat during long-term, high-load operation, the cooling fan 17 continuously exhausts the hot air inside the accommodating cavity 112 through forced convection, while introducing cooler air, forming an effective active heat dissipation cycle. This ensures that the core components of the test box 15 and the backlight control box 16 always operate within a safe temperature range, preventing signal drift, calculation errors, performance degradation, or even sudden shutdown caused by overheating, thereby ensuring the stability and reliability of long-term continuous testing.

[0053] In addition, in this embodiment, the base 11 can be detachably connected to the drive structure 30 via a quick-release knob 18, thereby facilitating the assembly and disassembly of the first carrier 10. In this embodiment, the specific structure of the second carrier 20 is similar to that of the first carrier 10, and the specific structure of the second carrier 20 will not be described in detail here.

[0054] In some embodiments, such as Figure 7 As shown, the testing mechanism 40 includes a linear motion structure 41 and a test piece 42 connected to the linear motion structure 41. The linear motion structure 41 drives the test piece 42 to move in three-dimensional space, and the test piece 42 is used to detect the material 400. Through the linear motion structure 41, the color analyzer can be precisely driven to any preset detection point on the display screen, thereby improving the comprehensiveness of the test. Optionally, the test piece 42 is a color analyzer. A color analyzer is a professional optical measurement device that can accurately measure key parameters of the display screen such as color coordinates, color temperature, brightness, and color gamut coverage, and present them as objective data. This changes the traditional judgment method that relies on subjective comparison by the human eye under specific lighting conditions, eliminates the risk of misjudgment caused by individual visual differences, changes in ambient light, or fatigue, and makes the test results objective, accurate, and quantifiable.

[0055] In some embodiments, such as Figure 6 As shown, multiple drive structures 30 are arranged at intervals along the second direction, and multiple test stations 300 are arranged at intervals along the second direction. Each drive structure 30 and each test station 300 corresponds one-to-one. Multiple first carriers 10 and multiple second carriers 20 are provided. Each drive structure 30 is used to drive each first carrier 10 and each second carrier 20 to slide back and forth between the transfer station 200 and the test station 300. By arranging multiple independent drive structures 30 and test stations 300 in parallel along the second direction, and equipping them with corresponding multiple first carriers 10 and multiple second carriers 20, a leap from single-line production to parallel production is achieved. Different vehicle displays can be calibrated and tested simultaneously and independently, resulting in a doubling of production efficiency and a significant increase in production capacity. Optionally, one of the test stations 300 can be reserved as a backup station. Optionally, the first direction and the second direction are perpendicular to each other.

[0056] This utility model also proposes a vehicle display production line, which includes a testing device. The specific structure of the testing device is as described in the above embodiments. Since this vehicle display production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0057] In summary, the testing device provided in this application automatically drives the first carrier 10 to slide back and forth between the material transfer station 200 and the testing station 300 by setting the drive structure 30, thereby realizing the automatic transfer and testing of the vehicle display screen. Operators or robotic arms only need to perform loading and unloading operations at the fixed material transfer station 200, which greatly improves the degree of automation, thereby significantly increasing the overall production cycle and improving testing efficiency. Furthermore, the first carrier 10 limits the material 400 by multiple limit blocks 13, effectively restricting the movement of the material 400 in all directions in the horizontal plane. Combined with the adsorption effect of the adsorption structure 12 on the material 400, it ensures that the posture of the material 400 remains stable throughout the entire transfer and testing process, thereby improving the reliability of the test.

[0058] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
