Description

Technical Field

[0001] This utility model relates to the field of semiconductor manufacturing equipment technology, and specifically discloses a product automatic counting and pouring box device. Background Technology

[0002] In the quality inspection process of the semiconductor industry, it is often necessary to transfer products from the test cassette to the target cassette to complete the process changeover. Current technology mainly relies on manual operation, where products are manually poured from the test cassette into the empty cassette. However, this method has significant drawbacks:

[0003] During manual material handling, product residue is easily left unremoved due to operational negligence, resulting in material loss or quality inspection errors. Manual counting is inefficient and prone to errors, and cannot provide accurate real-time feedback on product quantity. Furthermore, manual operation relies on human input and has a low degree of automation, making it difficult to meet the semiconductor industry's demand for high-precision and high-reliability production processes.

[0004] While some automatic material feeding devices exist in the existing technology, they generally lack accurate counting functions and have not been optimized for the material box conversion scenario in the quality inspection process, thus failing to effectively solve the core problems of leakage detection and quantity control.

[0005] Therefore, there is an urgent need for a device that can automatically unload materials and accurately count them in order to improve the efficiency and reliability of semiconductor quality inspection. Utility Model Content

[0006] This invention proposes an automatic product counting and dispensing device for material boxes. The device coordinates the operation of each component through a PLC controller. Once the sensor unit detects and confirms the position of the empty and full material boxes, the pushing cylinder is activated, pushing the product from the full box to the empty box. Simultaneously, the counting module counts the quantity in real time and displays it on the control screen. The entire process requires no manual intervention, ensuring efficient and accurate material box switching.

[0007] This utility model is implemented as follows: an automatic product counting and pouring box device, comprising:

[0008] The base has an empty material box and a full material box that are connected to each other on its top. The empty material box and the full material box are adjacent to each other and connected by a flow channel.

[0009] The material pushing mechanism includes a material pushing cylinder fixed to the base and a material pushing plate connected to the end of the piston rod of the material pushing cylinder. The cross-sectional shape of the material pushing plate matches the cross-sectional shape of the cavity of the full material box.

[0010] The detection control module includes:

[0011] The mounting bracket is vertically fixed to the top of the base, and the mounting bracket is located on the side of the empty material box away from the full material box, and faces the direction of the flow channel;

[0012] A photoelectric sensor, located in the middle of the mounting bracket, is used to detect the position status of the empty material box;

[0013] A counting sensor, located at the upper end of the mounting bracket, is used to collect the number of products passing through the guide channel in real time.

[0014] The PLC controller is electrically connected to the pusher cylinder, photoelectric sensor and counting sensor, and is configured to control the pusher cylinder to move according to the position signal of the photoelectric sensor and the numerical threshold of the counting sensor.

[0015] The human-machine interface unit includes a touch control screen that communicates with the PLC controller for setting parameters and displaying counting data.

[0016] As a preferred embodiment of the automatic product counting and pouring box device of this utility model, the pusher plate is provided with a buffer elastic pad, which is made of silicone material to prevent product collision damage.

[0017] As a preferred embodiment of the automatic product counting and material handling device of this utility model, the touch control screen is equipped with a USB interface, which supports exporting counting records in CSV format, including timestamps, batch numbers and transfer quantities, for quality traceability.

[0018] As a preferred embodiment of the automatic product counting and dispensing box device of this utility model, the top of the base is provided with a positioning groove, and the bottom of the empty box and the full box are respectively provided with positioning protrusions that match the positioning groove; the positioning groove is embedded with a magnetic suction component for adsorbing and fixing the positioning protrusions of the empty box and the full box.

[0019] The beneficial effects of this utility model are:

[0020] 1. By linking the PLC controller with the sensors, the feeding and counting processes can be completed without manual intervention, reducing manpower input and improving production efficiency.

[0021] 2. The counting sensor monitors the product quantity in real time. Combined with the matching design of the pusher plate and the full material box cavity, it ensures that there is no residue discharge and solves the problem of material leakage when manually pouring.

[0037] The human-machine interface unit includes a touch control screen 11 that is communicatively connected to the PLC controller 10, used for setting parameters and displaying counting data.

[0038] In this embodiment: photoelectric sensor 8 detects whether the empty material box 2 is in place, and counting sensor 9 collects the number of products in the guide channel 4 in real time and transmits the signal to PLC controller 10; after receiving the position signal, PLC controller 10 controls pusher cylinder 5 to drive pusher plate 6 to push the products in full material box 3; when the number of products detected by counting sensor 9 reaches a preset threshold, PLC controller 10 controls pusher cylinder 5 to stop moving; touch control screen 11 displays counting data in real time, and operators can set parameters through the interface and export historical records through USB interface for traceability; the whole process is automated, solving the problems of material leakage, counting error and low efficiency caused by manual material pouring.

[0040] In this embodiment, the silicone cushioning elastic pad 12 buffers the impact force on the product during the material pushing process, avoiding damage to the product due to rigid collision. It is especially suitable for the transfer of precision devices such as semiconductors, and improves the material protection performance.

[0046] The operator places the empty material box 2 into the empty material box 2 station of the base 1, and the full material box 3 into the full material box 3 station. The photoelectric sensor 8 detects whether the empty material box 2 is correctly positioned. If it is, it sends a signal to the PLC controller. The PLC controller 10 controls the pusher cylinder 5 to start, and the pusher plate 6 pushes the product along the cavity of the full material box 3, and enters the empty material box 2 through the guide channel 4. The counting sensor 9 collects the number of products passing through the guide channel 4 in real time and displays it synchronously on the touch control screen 11. When the count reaches the preset threshold (such as the rated capacity of the full material box 3), the PLC controller 10 instructs the pusher cylinder 5 to stop, completing one material unloading and counting process. The operator can view the current batch count data through the control screen, or export CSV format records (including timestamp, batch number, and transfer quantity) through the USB interface for quality traceability.
