Description

Technical Field

[0001] The present invention belongs to the technical field of thin sheet thickness detection, and particularly relates to a thin sheet thickness measuring device for feeding belt transmission. Background Art

[0002] During the production process of thin sheet materials, the qualification of final thickness detection is one of the key links in controlling product quality. Especially for some specific application scenarios, the thickness of the material directly affects the performance of the product, so strict requirements are imposed on the thickness of the thin sheet. The thickness measuring devices available on the market can be roughly divided into two types: mechanical contact thickness measurement and optical non-contact thickness measurement. However, in practical applications, both of these methods have certain limitations and challenges:

[0003] Firstly, neither mechanical contact thickness measurement nor optical non-contact thickness measurement usually uses a feeding belt (belt) to transport thin sheets. This is because the vibration or jitter generated during the operation of the feeding belt may affect the measurement stability, and the elasticity of the feeding belt cannot provide a consistent support surface, which may cause shape changes in softer or easily deformable thin sheets, thereby affecting the measurement accuracy. For this reason, mechanical contact thickness measurement turns to use a conveying measurement platform, while optical non-contact measurement relies on other transmission mechanisms to ensure accuracy. This makes the transmission system of thin sheets much more complex than traditional ones during thickness detection, increasing the cost and technical difficulty.

[0004] Secondly, although popular optical measurement methods can provide high-precision results, when faced with uneven or transparent materials on the surface, the recognition difficulty increases significantly. The complex surface structure and the problems of light refraction and reflection make it difficult for traditional optical measurement techniques to accurately capture the true edge of the thin sheet, resulting in errors. This situation not only limits the application range of optical measurement methods, but also poses higher requirements for their accuracy.

[0005] Finally, optical measurement methods have strict requirements for the working environment. Dust, oil, etc. will interfere with the light propagation and affect the measurement accuracy. Extra cleaning and maintenance are required in a harsh environment, increasing the operation complexity and cost, and may reduce the efficiency. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a thin sheet thickness measuring device for feeding belt transmission to solve the problems existing in the above background art.

[0007] To solve the above technical problems, the first technical solution of the present invention is a thin sheet thickness measuring device for feeding belt transmission. The thin sheet thickness measuring device includes a feeding belt, and the feeding belts are arranged adjacent to each other in parallel along the width direction of the feeding belt itself, and there is a gap between adjacent feeding belts; a thickness measuring platform, which is arranged on the traveling route of the feeding belt. The thickness measuring platform is composed of a thickness measuring table surface, a contact type thickness measuring probe and a lifting component. The thickness measuring platform is arranged at the gap, and the contact type thickness measuring probe is arranged at the output end of the lifting component. The contact type thickness measuring probe is located in the vertical direction of the thickness measuring platform; when the feeding belt transports the thin sheet to the thickness measuring platform, the lifting component controls the contact type thickness measuring probe to move towards the thin sheet to complete the thickness measuring operation of the thin sheet.

[0008] Preferably, a feeding table and a material taking component are added to realize automatic loading and unloading: the thin sheet thickness measuring device includes: a feeding table, on which a lifting table for stacking and placing thin sheets is arranged; a material taking component, which is used for the movement of the thin sheet between the feeding table and the feeding belt; the material taking component is composed of a material taking suction cup, a first linear transmission component and a second linear transmission component. The material taking suction cup is arranged on the moving end of the first linear transmission component, and the first linear transmission component is arranged on the moving end of the second linear transmission component.

[0009] Furthermore, the layout of the feeding table and the material taking suction cup is optimized to improve the loading rate: the feeding belts are arranged with the feeding tables on both sides in the width direction of the feeding belt itself. The feeding tables are respectively a first feeding table and a second feeding table; the material taking suction cups on the moving end of the first linear transmission component are respectively a first material taking suction cup and a second material taking suction cup. The first material taking suction cup and the second material taking suction cup are arranged in a row along the width direction of the feeding belt, and the distance between the first material taking suction cup and the second material taking suction cup is equal to the distance from the to-be-tested feeding table or the qualified feeding table to the feeding belt, so as to facilitate the material taking component to take materials back and forth between the first feeding table and the second feeding table.

[0010] Furthermore, fully automatic loading and unloading is realized: the feeding table is divided into a to-be-tested feeding table and a qualified feeding table. The to-be-tested feeding table is used for placing thin sheets to be thickness detected, and the qualified feeding table is used for placing thin sheets that are qualified after being detected by the thickness measuring platform; the material taking component is divided into a first material taking component and a second material taking component. The first material taking component is used for moving the thin sheets on the to-be-tested feeding table to the feeding belt, and the second material taking component is used for moving the thin sheets that are qualified after being detected by the thickness measuring platform to the qualified feeding table.

[0011] Further, the automation degree of the induction probe moving device is increased in the corresponding area: a first induction probe is provided on the thickness measurement platform, and the first induction probe is used to sense whether there is a thin sheet moving to the thickness measurement platform on the feeding belt; a second induction probe is provided on the suction cup of the second material taking component, and the second induction probe is used to sense whether there is a thin sheet moving to the qualified material table on the feeding belt; a third induction probe is provided at the top of the material table, and the third induction probe is used to sense whether the lifting table raises the height where the thin sheet is located, so as to facilitate the material taking component to take the material from the material table.

[0012] Preferably, a defective product processing component is added to improve the defective product processing efficiency: the thin sheet thickness measurement device includes: a defective product processing component, and the defective product processing component is used to process the abnormal thin sheets after being detected by the thickness measurement platform; the defective product processing component is composed of a conveyor belt, a material taking component and a discharging container, the conveyor belt is docked with the feeding belt, and the material taking component is used to move the abnormal thin sheets after being detected by the thickness measurement platform from the conveyor belt to the discharging container.

[0013] Further, the defective products are classified and the processing method is optimized: the abnormal thin sheets after being detected by the thickness measurement platform are divided into thin sheets with insufficient thickness, thin sheets with excessive thickness and composite thick thin sheets; the discharging container is sequentially provided with a first discharging container, a second discharging container and a third discharging container for placing thin sheets with insufficient thickness, thin sheets with excessive thickness and composite thick thin sheets; the first discharging container and the second discharging container are respectively arranged on both sides of the conveying direction of the conveyor belt, and the third discharging container is used at the end of the conveying direction of the conveyor belt.

[0014] Further, the structure of the material taking component is disclosed: the material taking component is composed of a third suction cup, a third linear transmission component and a fourth linear transmission component, the third suction cup is arranged on the moving end of the third linear transmission component, and the third linear transmission component is arranged on the moving end of the fourth linear transmission component; the transmission direction of the fourth linear transmission component is located on the first discharging container and the second discharging container.

[0015] In order to solve the above technical problems, the second technical solution of the present invention is a method for using a thin sheet thickness measurement device with a feeding belt transmission, which applies the thin sheet thickness measurement device in the first technical solution, and the method is as follows:

[0016] S1. Stack the thin sheets to be measured on the material table to be measured, and ensure that the lifting table adjusts the uppermost thin sheet to a height suitable for the material taking component to grasp;

[0017] S2. The first material picking component moves above the material platform to be measured through the first linear transmission component and the second linear transmission component, and uses the first material picking suction cup to pick up the topmost thin sheet; the first material picking component transports and places the picked thin sheet on the feeding belt, and the feeding belt starts to run to transport the thin sheet towards the thickness measurement platform;

[0018] S3. When the thin sheet is transported to the thickness measurement platform, the first induction probe senses the presence of the thin sheet; the lifting component lowers the contact thickness measurement probe to contact the surface of the thin sheet for thickness measurement; after the measurement is completed, the contact thickness measurement probe rises back to its original position;

[0019] S4. If the thin sheet is qualified, the second material picking component picks up the thin sheet from the feeding belt and transports it to the qualified material platform for stacking; if the thin sheet is unqualified, the feeding belt transports the thin sheet to the defective product processing component.

[0020] Preferably, the material picking component in the defective product processing component moves the thin sheet to the corresponding discharging container according to the specific abnormal type of the thin sheet; the thin sheet with insufficient thickness refers to the thin sheet with a thickness lower than the normal standard, the thin sheet with excessive thickness refers to the thin sheet with a thickness higher than the normal standard, and the composite thick thin sheet refers to the thin sheet with a thickness greater than several times the normal standard.

[0021] The technical effects of the present invention are mainly reflected in the following aspects:

[0022] By optimizing the layout of the feeding belt and increasing the gap, it not only ensures the stability during transportation but also makes precise measurement possible; the thickness measurement platform is set at the gap of the feeding belt, avoiding direct contact with the feeding belt, thereby reducing the measurement error caused by the elasticity or unevenness of the feeding belt. This method can adapt to thin sheets of different thicknesses and improve the versatility of the equipment. The contact thickness measurement probe is adopted to directly physically contact the thin sheet to be measured, effectively avoiding the error problem caused by light refraction and reflection in the optical measurement method; at the same time, compared with the high dependence on a clean environment in the optical measurement method, the contact thickness measurement method provided in this embodiment reduces the requirements for the environment, reduces the interference of external factors such as dust and oil stains, simplifies the maintenance process, and improves the work efficiency.

[0023] The first material platform and the second material platform are respectively arranged on both sides in the width direction of the feeding belt, allowing the equipment to process more thin sheets simultaneously and improving the work efficiency; it realizes more efficient material management and processing capabilities, and improves the space utilization rate and production efficiency. Then, the material picking suction cups are respectively the first material picking suction cup and the second material picking suction cup to ensure that the positions of the two sides of the material platform can be covered; it ensures that the material picking component can move back and forth between the first material platform and the second material platform efficiently, realizing an automated material handling process. The design of the first material picking suction cup and the second material picking suction cup enables the material picking component to quickly switch between the two material platforms, reducing the waiting time and improving the automation level.

Therefore, it will not be elaborated in this embodiment.

[0034] Embodiment 1

[0035] See Figure 1 、 Figure 2 As shown in and , this embodiment discloses a thin sheet thickness measuring device for the transmission of a feeding belt 1. The thin sheet thickness measuring device includes a feeding belt 1, and the feeding belts 1 are arranged adjacent to each other in parallel along the width direction of the feeding belt 1 itself. There is a gap 11 between adjacent feeding belts 1. By optimizing the layout of the feeding belt 1 and increasing the gap, the stability during transportation is ensured, and the possibility of accurate measurement is provided. A thickness measuring platform 2 is provided on the traveling route of the feeding belt 1. The thickness measuring platform 2 is composed of a thickness measuring tabletop 21, a contact type thickness measuring probe 22, and a lifting component 23. The thickness measuring platform 2 is arranged at the gap 11, avoiding direct contact with the feeding belt 1, thereby reducing the measurement error caused by the elasticity or unevenness of the feeding belt 1. The contact type thickness measuring probe 22 is arranged at the output end of the lifting component 23, and the contact type thickness measuring probe 22 is located in the vertical direction of the thickness measuring platform 2. The contact type thickness measuring probe 22 can be controlled by the lifting component 23 to accurately move to the surface of the thin sheet when measurement is required to complete the thickness measurement operation. This method can adapt to thin sheets of different thicknesses and improves the versatility of the device. When the feeding belt 1 transports the thin sheet to the thickness measuring platform 2, the lifting component 23 controls the contact type thickness measuring probe 22 to move towards the thin sheet to complete the thickness measurement operation of the thin sheet. By using the contact type thickness measuring probe 22, direct physical contact with the thin sheet to be measured is achieved, effectively avoiding the error problem caused by light refraction and reflection in the optical measurement method. At the same time, compared with the high dependence on a clean environment in the optical measurement method, the contact type thickness measuring method provided in this embodiment reduces the requirements for the environment, reduces the interference of external factors such as dust and oil stains, simplifies the maintenance process, and improves the work efficiency.

[0036] See Figure 3, the thin sheet thickness measuring device includes a material table 3, and a lifting table for stacking and placing thin sheets is arranged on the material table 3; this lifting table can move up and down to ensure that the uppermost thin sheet is in the best position for each material taking operation, facilitating the operation of the material taking component 4. The material taking component 4 is a key component for realizing the automatic transfer of thin sheets between the material table 3 and the feeding belt 1, and the material taking component 4 is used for the movement of thin sheets between the material table 3 and the feeding belt 1; the material taking component 4 is composed of a material taking suction cup, a first linear transmission component 42, and a second linear transmission component 43. The material taking suction cup is arranged on the moving end of the first linear transmission component 42 and is responsible for directly sucking the thin sheet and completing the handling task. The first linear transmission component 42 is arranged on the moving end of the second linear transmission component 43.,

[0037] See Figure 3 , Figure 4 , the feeding belt 1 is provided with the material table 3 on both sides in its own width direction, and the material table 3 is respectively a first material table 31 and a second material table 32. The above setting allows the device to process more thin sheets at the same time, improving the work efficiency; by arranging the material table 3 on both sides of the feeding belt 1, more efficient material management and processing capabilities are achieved, improving the space utilization rate and production efficiency. The material taking suction cups on the moving end of the first linear transmission component 42 are respectively a first material taking suction cup 411 and a second material taking suction cup 412, and the first material taking suction cup 411 and the second material taking suction cup 412 are arranged along the width direction of the feeding belt 1 to ensure that the positions of the material tables 3 on both sides can be covered. The distance between the first material taking suction cup 411 and the second material taking suction cup 412 is equal to the distance from the material table 51 to be measured or the qualified material table 52 to the feeding belt 1, so as to facilitate the material taking component 4 to take materials back and forth between the first material table 31 and the second material table 32; ensure that the material taking component 4 can move back and forth between the first material table 31 and the second material table 32 efficiently, realizing an automated material handling process. The design of the first material taking suction cup 411 and the second material taking suction cup 412 enables the material taking component 4 to quickly switch between the two material tables 3, reducing the waiting time and improving the automation level.

[0038] See Figure 4, the material platform 3 is divided into a to-be-tested material platform 51 and a qualified material platform 52. The to-be-tested material platform 51 is used to place the thin sheets to be thickness-tested, and the qualified material platform 52 is used to place the thin sheets that are qualified after being detected by the thickness measurement platform 2. Dividing the material platform 3 into the to-be-tested material platform 51 and the qualified material platform 52 not only improves the clarity of material management but also facilitates the automated processing of subsequent processes; it reduces quality problems caused by human errors and improves production efficiency. The material taking component 4 is divided into a first material taking component 534 and a second material taking component 544. The first material taking component 534 is used to move the thin sheet on the to-be-tested material platform 51 onto the feeding belt 1 to prepare for entering the thickness measurement link. The second material taking component 544 is used to move the thin sheets that are qualified after being detected by the thickness measurement platform 2 onto the qualified material platform 52.

[0039] There is a first induction probe on the thickness measurement platform 2. The first induction probe is used to sense whether there is a thin sheet moving to the thickness measurement platform 2 on the feeding belt 1; it can ensure that only when the thin sheet accurately reaches the thickness measurement position, the contact thickness measurement probe 22 will start to measure, avoiding measurement errors or equipment idling caused by improper timing. There is a second induction probe on the material taking suction cup of the second material taking component 544. The second induction probe is used to sense whether there is a thin sheet moving to the qualified material platform 52 on the feeding belt 1; the existence of the second induction probe enables the second material taking component 544 to identify and carry the qualified thin sheets in a timely and accurate manner, ensuring the correctness and efficiency of material classification. There is a third induction probe at the top of the material platform 3. The third induction probe is used to sense whether the lifting platform raises the height of the thin sheet, so as to facilitate the material taking component 4 to take the material from the material platform 3; it ensures that the topmost thin sheet is at the optimal height before each material taking, improving the success rate and accuracy of the material taking process and reducing the material taking failures caused by uneven stacking or inappropriate height of the thin sheets. By setting induction probes at key positions, real-time monitoring of the position of the thin sheets is achieved, enhancing the automation ability and response speed of the system and reducing the need for human intervention; the use of each induction probe not only improves the accuracy of the operation but also optimizes the coordination of the entire process. For example, it ensures that thickness measurement is only carried out when the thin sheet is correctly positioned, and the material taking action is only executed under appropriate conditions.

[0040] See Figure 5 , Figure 6, the thin sheet thickness measuring device includes a defective product processing component 6 for processing the abnormal thin sheets after being detected by the thickness measuring platform 2; the defective product processing component 6 is composed of a feeding belt 61, a material taking component 62 and a discharging container. The feeding belt 61 is docked with the feeding belt 1 and is specifically used for transporting the thin sheets that are determined to be abnormal or unqualified after being detected by the thickness measuring platform 2. The material taking component 62 is used to move the abnormal thin sheets after being detected by the thickness measuring platform 2 from the feeding belt 61 to the discharging container; the design of this component is similar to the aforementioned material taking component 4, including necessary linear transmission components and material taking suction cups, etc., to achieve precise picking and placing operations.

[0041] The abnormal thin sheets after being detected by the thickness measuring platform 2 are divided into thin sheets with insufficient thickness, thin sheets with excessive thickness and composite over-thick thin sheets. The composite over-thick thin sheets are mainly caused by multiple thin sheets being stacked together; by classifying and storing different types of unqualified thin sheets, it is not only convenient for subsequent quality analysis and process improvement, but also can effectively prevent the confusion between different types of defective products, improving the accuracy of quality management. The discharging container is sequentially provided with a first discharging container 631, a second discharging container 632 and a third discharging container 633 for placing thin sheets with insufficient thickness, thin sheets with excessive thickness and composite over-thick thin sheets; the first discharging container 631 and the second discharging container 632 are respectively arranged on both sides of the feeding direction of the feeding belt 61, and the third discharging container 633 is used at the end of the feeding direction of the feeding belt 61 to ensure that the composite over-thick thin sheets can directly enter the third discharging container 633 through the feeding belt 61, avoiding the use of a material taking suction cup for handling, thus reducing the impact on the main process. The material taking component 62 is composed of a third material taking suction cup 621, a third linear transmission component 622 and a fourth linear transmission component 623. The third material taking suction cup 621 is arranged on the moving end of the third linear transmission component 622, and the third linear transmission component 622 is arranged on the moving end of the fourth linear transmission component 623; the transmission direction of the fourth linear transmission component 623 is located on the first discharging container 631 and the second discharging container 632. The material taking component 62 designed with a double linear transmission component can achieve high-precision thin sheet handling operations, ensuring that each unqualified thin sheet can be accurately placed into the corresponding discharging container, improving the operation efficiency; and a special channel for the composite over-thick thin sheets to directly enter the third discharging container 633 is set, avoiding the interference of such relatively special defective products on the main process, simplifying the processing steps, and improving the overall production efficiency.

[0042] Embodiment 2

[0043] This embodiment discloses a method for using a thin sheet thickness measuring device transmitted by a feeding belt 1, applying the thin sheet thickness measuring device described in Embodiment 1. The method is as follows:

[0044] S1. Preparation

[0045] Stacking of wafers to be measured: First, stack the wafers to be measured neatly on the material platform 51 to be measured.

[0046] Height adjustment: Ensure that the lifting table automatically adjusts the height of the uppermost wafer according to the feedback of the third induction probe so that it is in a position suitable for the first material taking component 534 to grasp.

[0047] S2. Material taking and initial handling

[0048] Positioning and suction: The first material taking component 534 moves to directly above the material platform 51 to be measured through the first linear transmission component 42 and the second linear transmission component 43, and accurately adsorbs the uppermost wafer using the first material taking suction cup 411.

[0049] Handling to the feeding belt 1: Subsequently, the first material taking component 534 transports and places the adsorbed wafer on the feeding belt 1. At this time, the feeding belt 1 starts to run and transports the wafer smoothly towards the thickness measurement platform 2.

[0050] S3. Thickness measurement

[0051] Induction confirmation: When the wafer is transported to the thickness measurement platform 2, the first induction probe will sense the presence of the wafer and trigger the subsequent operation process.

[0052] Thickness detection: Then, the lifting component 23 controls the contact thickness measurement probe 22 to descend until it contacts the surface of the wafer to complete the thickness measurement. After the measurement is completed, the contact thickness measurement probe 22 rises back to the initial position.

[0053] S4. Treatment of qualified and unqualified products

[0054] Treatment of qualified products: If the thickness of the wafer meets the preset standard, the second material taking component 544 picks up the wafer from the feeding belt 1 and transports it to the qualified material platform 52 for stacking.

[0055] Treatment of unqualified products: If the wafer is unqualified (including insufficient thickness, excessive thickness or excessive compound thickness), the feeding belt 1 will continue to transport the wafer forward to the unqualified product treatment component 6. In the unqualified product treatment component 6, the material taking assembly 62 moves the wafer to the corresponding discharging container according to the specific abnormal type of the wafer (obtained through system analysis):

[0056] Wafers with insufficient thickness: Put into the first discharging container 631;

[0057] Wafers with excessive thickness: Put into the second discharging container 632;

[0058] Composite over-thick flakes: Since such flakes are usually caused by stacking multiple layers of flakes, they will be directly transported to the third discharging container 633 at the end of the feeding belt 61 without being carried by the picking suction cups.

[0059] In addition; as common knowledge in this industry; the first picking suction cup 411, the second picking suction cup 412, and the third picking suction cup 621 mentioned above; the first linear driving component 42, the second linear driving component 43, the third linear driving component 622, and the fourth linear driving component 623; the first induction probe, the second induction probe, and the third induction probe. The above are common knowledge; therefore, the principles and structures thereof will not be described in detail.

[0060] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.

Stack the sheets to be tested on the test platform and ensure that the lifting platform adjusts the top sheet to a height suitable for the material picking component to grab; S2, the first material picking component moves to the top of the material table to be measured through the first linear transmission component and the second linear transmission component, and uses the first material picking suction cup to pick up the topmost thin sheet; the first material picking component transports the sucked thin sheet and places it on the feeding belt, and the feeding belt starts to run and transmits the thin sheet to the thickness measuring platform; S3. When the sheet is transported to the thickness measuring platform, the first sensing probe senses the presence of the sheet; the lifting component causes the contact thickness measuring probe to descend and contact the sheet surface to measure the thickness; after the measurement is completed, the contact thickness measuring probe rises back to its original position; S4. If the slices are qualified, the second material picking component picks up the slices from the feeding belt and moves them to the qualified material table for stacking; if the slices are unqualified, the feeding belt transfers the slices to the defective product processing component.

10. The method for using the sheet thickness measuring device according to claim 9, characterized in that: The material taking component in the defective product handling part moves the thin slices to the corresponding material discharging container according to the specific abnormal type of the thin slices; A thin film with insufficient thickness refers to a thin film with a thickness lower than the normal standard, a thin film with excessive thickness refers to a thin film with a thickness higher than the normal standard, and a thin film with compound excessive thickness refers to a thin film with a thickness several times greater than the normal standard.
