Abstract
Description
Technical fields:
[0001] This utility model relates to the field of industrial automation equipment manufacturing technology, specifically a multi-production line continuous automatic counting and sampling inspection device with reasonable structure and reliable operation, capable of automatically sampling and inspecting products from multiple production lines with different production efficiencies. Background technology:
[0002] In existing technologies, to ensure product manufacturing quality and monitor equipment production status, tensile tests are conducted on a per-unit quantity during product manufacturing, and the test results are recorded.
[0003] Taking tensile strength testing of products on a production line as an example, tensile strength tests are prone to failure when the production line equipment changes products or materials. This necessitates sampling the first product for judgment. However, untimely or forgotten manual sampling can easily lead to a large number of defective products. When multiple production lines and multiple groups of equipment are operating simultaneously, the different product types produced by each group and the varying processing times for each product make it impossible to conduct timely sampling according to the required unit quantity. This results in substandard sampling and an inability to promptly identify production quality problems. Furthermore, in actual production, it is easy to fail to operate according to the required unit sampling quantity. Since multiple devices on the production line are producing the same product simultaneously, errors can easily occur in the matching of sampling results with the equipment. For example, samples to be sampled may be placed together, making it unclear which device produced the defective product. This hinders the timely detection of production equipment abnormalities and increases the probability of a large number of defective products. Summary of the Invention:
[0004] This invention addresses the shortcomings and deficiencies of existing technologies by proposing a multi-production line continuous automatic counting and sampling inspection device that is structurally sound, reliable in operation, and capable of automatically sampling and inspecting products from multiple production lines with different production efficiencies.
[0005] This utility model achieves its purpose through the following measures:
[0006] A multi-production-line continuous automatic counting and sampling inspection device is characterized by comprising a sampling and handling mechanism for picking up and sampling products from the production line feed end, and a sampling controller connected to the sampling and handling mechanism. The sampling controller is connected to a counting / handling controller, which is also connected to a multi-production-line counting controller for collecting product quantity information from multiple production lines. The signal input terminal of the multi-production-line counting controller is connected to the signal output terminals of two or more single-production-line counting controllers, and the two or more single-production-line counting controllers are respectively configured to correspond one-to-one with two or more single production lines. Each single production line is equipped with a photoelectric counting sensor or a contact sensor connected to the corresponding single-production-line counting controller.
[0007] Both the multi-line counting controller and the single-line counting controller described in this utility model can be implemented using a PLC controller. The PLC controller mentioned in this utility model can be a Mitsubishi FX5U-32MT model controller.
[0008] The sampling and handling mechanism of this utility model is implemented by a handling robot. The motor control signal input terminal of the handling robot is connected to the output terminal of the sampling controller. The handling robot is also equipped with a sampling product information reading component. The sampling product information reading component is equipped with an RFID tag reader or a camera. The signal output terminal of the sampling product information reading component is connected to the counting / handling controller, which is used to upload the information of the sampling product, such as image data or barcode tag data, to the counting / handling controller or the host computer.
[0009] Furthermore, this utility model also includes a host computer connected to the counting / transporting controller. The data received by the counting / transporting controller can be uploaded to the host computer, and the host computer can issue sampling control commands to the counting / sampling controller. The counting / sampling controller is implemented using a PLC controller.
[0010] This utility model also includes a test controller connected to the test equipment. The test controller is implemented using a microcontroller or PLC controller and is used to receive the test data output by the test equipment. The test equipment is a conductive wire tensile testing device. The host computer is connected to the conductive wire tensile testing device to directly receive and store the product tensile testing parameters.
[0011] The feeding end of the single production line of this utility model is also equipped with a product feeding information collection component. The product feeding information collection component adopts an RFID tag reader or a camera. The data output end of the product feeding information collection component is connected to the counting / transporting controller to complete the preliminary collection of product data of the single production line.
[0012] The single production line of this utility model is equipped with a conveying mechanism, which is implemented by a conveyor belt or a conveyor roller. The single production line is arranged sequentially along the product conveying direction with a loading position, a pressing position, and a unloading position. Conveying mechanisms are respectively provided between the loading position and the pressing position, and between the pressing position and the unloading position, to realize the transfer of the products to be processed between different workstations. The photoelectric counting sensor or contact sensor is set on the side of the conveying mechanism to collect the position information of the products being transported on the conveying mechanism and send it to the corresponding single production line counting controller.
[0013] In operation, this invention uses proximity photoelectric counting sensors or photoelectric counting sensors on each production line to collect the product position data for each individual production line. The collected data is then sent to the corresponding single-line counting controller to collect the number of products processed on each production line. Data collected by each single-line counting controller is sent to a multi-line counting controller, which then sends the aggregated data via RS485 to a counting / transfer controller. Based on a preset sampling number, the controller drives a sampling and transfer mechanism to grab the sampled products from the material bin at the unloading end. During the grabbing process, the sampled products must be counted. The product label is read and recorded, and the read and recorded information is fed back to the counting / transporting controller or the host computer. The sampling and transporting mechanism sends the product to be tested to the testing equipment. The data of the product to be tested in the testing equipment (including model data and test result data) is collected by the testing controller and fed back to the host computer. If the testing equipment malfunctions, the host computer sends a stop command to the counting / transporting controller. The counting / transporting controller sends the sampling stop command to the sampling controller via the RS485 communication circuit. The sampling controller drives the sampling and transporting mechanism to stop transporting until the malfunction is resolved.
[0014] Compared with existing technologies, this invention can quickly and efficiently realize the grouping and statistical analysis of different categories of work products of different grouping work devices and the automatic handling of work sampling products. It avoids the situation where the number of different categories of work products of different grouping work devices cannot be automatically summarized and counted due to manual inspection, resulting in inaccurate control and missed inspections of product tensile strength sampling. It can realize the marking and handling of sampling products of different grouping work devices according to the unit quantity required for sampling of their work products, and prepare for accurate recording of sampling inspection of products corresponding to different grouping equipment. In addition, by connecting to the testing equipment through the host computer, the working status and inspection quantity of the testing equipment can be read, compared with the sampling records and stored to avoid the omission of sampling product records.

[0019] As attached Figure 1 As shown, this utility model proposes a multi-production line continuous automatic counting and sampling inspection device, which includes a sampling and handling mechanism 1 for picking up and sampling products from the production line feed end, and a sampling controller 2 connected to the sampling and handling mechanism 1. The sampling controller 2 is connected to a counting / handling controller 3, and the counting / handling controller 3 is also connected to a multi-production line counting controller 4 for collecting product quantity information from multiple production lines. The signal input terminal of the multi-production line counting controller 4 is connected to the signal output terminals of two or more single production line counting controllers 5 respectively. The two or more single production line counting controllers 5 are respectively set to correspond one-to-one with two or more single production lines 6. Each single production line 6 is equipped with a photoelectric counting sensor or contact sensor 7 connected to the corresponding single production line counting controller 5.
[0020] The sampling and handling mechanism 1 of this utility model is implemented by a handling robot. The motor control signal input terminal of the handling robot is connected to the output terminal of the sampling controller 2. The handling robot is also equipped with a sampling product information reading component 8. The sampling product information reading component 8 is equipped with an RFID tag reader or a camera. The signal output terminal of the sampling product information reading component 8 is connected to the counting / handling controller, which is used to upload the information of the sampling product, such as image data or barcode tag data, to the counting / handling controller 3 or the host computer 9.
[0021] The counting / transporting controller 3 of this utility model is connected to the host computer 9. The data received by the counting / transporting controller 3 can be uploaded to the host computer 9. The host computer 9 can send sampling control commands to the counting / sampling controller 3. The counting / sampling controller 3 is implemented using a PLC controller.
[0022] This utility model also includes a test controller 11 connected to the test equipment 10. The test controller 11 is implemented using a microcontroller or PLC controller and is used to receive the test data output by the test equipment 10. The test equipment 10 is a conductive wire tensile testing device. The host computer 9 is connected to the conductive wire tensile testing device and directly receives and stores the product tensile testing parameters.
[0023] The feeding end of the single production line 6 of this utility model is also provided with a product feeding information acquisition component 12. The product feeding information acquisition component 12 adopts an RFID tag reader or a camera. The data output end of the product feeding information acquisition component 12 is connected to the counting / transporting controller 3 to complete the preliminary acquisition of product data of the single production line 6.
[0024] The single production line 6 of this utility model is equipped with a conveying mechanism, which is implemented by a conveyor belt or a conveyor roller. The single production line 6 is arranged with a loading position, a pressing position and a unloading position in sequence along the product conveying direction. Conveying mechanisms are respectively provided between the loading position and the pressing position and between the pressing position and the unloading position to realize the transfer of the product to be processed between different work positions. The photoelectric counting sensor or contact sensor 7 is arranged on the side of the conveying mechanism to collect the position information of the product being transported on the conveying mechanism and send it to the corresponding single production line counting controller.
[0025] Example:
[0026] This example provides a multi-production-line continuous automatic counting and sampling inspection device, as shown in the attached document. Figure 2 As shown, there are four single production lines 6. The products processed by the four single production lines 6 have different models and specifications. Material boxes are arranged at the loading and unloading ends of each production line. The multi-production line continuous automatic counting and sampling device includes: a host computer 9, a test controller 11, a counting / transfer controller 3, a multi-production line counting controller 4, and four single production line counting controllers 5 corresponding to the four production lines. Each single production line counting controller 5 realizes grouped statistical counting of each production line.
[0027] Each production line is also equipped with a product loading information acquisition component 12 that is connected to the single production line counting controller 5 to read the loading product information;
[0028] In this example, the product models in the loading bins of each production line may not be the same. Each production line counting controller 5 needs to classify and summarize the product information of each production line. Each production line is equipped with sensors that are connected to the production line counting controller 5. Multiple photoelectric induction counting sensors are used to obtain the position status information of the products being processed, thereby understanding the number of products on the production line and the number of products being unloaded at the unloading end of the production line, providing a basis for sampling inspection. The data collected by each production line counting controller 5 is summarized to the multi-production line counting controller 4, and the multi-production line counting controller 4 transmits the product information and counting information stored in each production line to the counting / transfer controller 3. The counting / transfer controller 3 stores the products to be sampled for each group of equipment. The system receives product information and sends a sampling inspection command to the sampling controller 2. Once the product count at the feed end of the single production line reaches its sampling quantity, the sampling controller 2 communicates with the sampling and handling mechanism 1 to locate the storage position of the product to be inspected. The sampling and handling mechanism 1 reads the product information of the product to be inspected and sends it back to the host computer of the automatic sampling equipment. Then, it moves the product to be inspected to the testing equipment. The testing controller collects relevant data from the testing equipment during the testing process and sends it back to the host computer. If the testing equipment malfunctions during this process, the host computer can issue a command to the counting / handling controller 3, and then control the sampling controller 2 to stop driving the sampling and handling mechanism 1 to perform the sampling and handling operation until the malfunction is resolved.
[0029] In this example, all products under inspection are thermal printheads, and the testing equipment is a tensile testing device that records the tensile force value of the conductive wire. This example enables real-time feedback of tensile testing and recording of products, avoiding situations such as missed inspections in unit quantity sampling caused by manual sampling and the inability of the product sampling of the pressing device to correspond to the device. While improving work efficiency, this equipment can also ensure automatic control of the tensile sampling operation of products and accurate correspondence between tensile test records and product pressing devices.
