Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to product sorting field, concretely relates to a product counting feeding tray and a product sorting line. BACKGROUND
[0002] Product sorting refers to the process of classifying and selecting articles according to certain standards, with the purpose of facilitating further processing, use or handling. For example, in the manufacturing industry, many parts need to be sorted in order to facilitate their installation in the corresponding parts.
[0003] In the product sorting process, the product is sucked by the tool head suction nozzle on the mechanical hand, and then the mechanical hand is rotated to the feeding tray by the servo motor. When the position of the product is consistent with the groove on the feeding tray for placing the product, the tool head moves down, and the product is unloaded into the groove of the feeding tray. The operation is repeated until the feeding tray is fully loaded. Then the linear motor moves the feeding tray away, and the next work station picks up the fully loaded feeding tray to the rack by the pick-and-place machine. Then the linear motor picks up a new empty feeding tray within the range of the mechanical hand, and starts a new picking.
[0004] However, if the tool head suction nozzle on the mechanical hand fails to suck the product during this process, there will be a missing product on the feeding tray, resulting in insufficient number of products for subsequent work. Therefore, there is a need for a feeding tray to solve the problem of empty grooves on the final feeding tray caused by the mechanical hand picking or other reasons. SUMMARY
[0005] The purpose of the utility model is to solve at least one of the above problems by providing a product counting feeding tray and a product sorting line, to solve the problem of empty grooves on the feeding tray for placing products in the product sorting process in the prior art, and to prevent the appearance of blank grooves without products on the feeding tray and ensure that the feeding tray is fully loaded with products.
[0006] The purpose of the utility model is achieved through the following technical solutions:
[0007] One of the technical solutions of the utility model is to provide a product counting feeding tray, which is arranged on a product sorting line. A through groove and a groove are arranged on the feeding tray, and the groove is in communication with the through groove.
[0008] A distance sensor is arranged at the edge of the feeding tray, and the distance sensor is located at the end of the through groove.
[0009] A weight sensor is arranged inside the feeding tray.
[0010] Further, the through groove penetrates the feeding tray, and the distance sensor is arranged towards the through groove. The distance sensor is arranged at the end of the feeding tray,
[0011] Further, when the through grooves are arranged in multiple, the through grooves are parallel to each other, so as to prevent the through grooves, the grooves and the distance sensors from affecting the product quantity determination.
[0012] Further, when the through grooves are arranged in multiple, the number of the distance sensors is equal to the number of the through grooves, and the distance sensors correspond to the through grooves one by one.
[0013] Further, when the product is located in the groove, the rays of the distance sensor are shot on the product, the product blocks the rays of the distance sensor from being shot out of the groove, so that the distance sensor can determine the position of the product according to the measurement data, and further determine whether the position of the product placed by the mechanical hand is correct.
[0014] Further, the distance sensor comprises any one of an infrared distance sensor, a laser distance sensor and an ultrasonic distance sensor.
[0015] Further, one groove is communicated with one through groove only, and one distance sensor is arranged at the end of each through groove, so as to be used for determining the quantity of the product in the corresponding through groove.
[0016] Further, the weight sensors are arranged in multiple, one of which is arranged at the center of the feeding tray, and the rest of the weight sensors are symmetrically arranged in the feeding tray.
[0017] Further, the feeding tray is divided into two layers, and the weight sensors are arranged between the upper layer and the lower layer.
[0018] Further, the weight sensor comprises any one of a bending beam sensor, a piezoresistive sensor and a capacitive sensor.
[0019] The second technical scheme of the utility model provides a product sorting line, which comprises the feeding tray, a mechanical hand arranged on the product sorting line and used for grabbing the product and placing the product in the groove of the feeding tray, and a control system electrically connected with the mechanical hand.
[0020] The distance sensor and the weight sensor on the feeding tray are electrically connected with the control system on the product sorting line.
[0021] Further, when the product is placed on the feeding tray by the mechanical hand, the product is preferentially placed in the groove farthest from the ray port of the distance sensor.
[0022] Further, the control system comprises a controller and an alarm, and the alarm, the mechanical hand, the distance sensor and the weight sensor are electrically connected with the controller.
[0023] Further, when the product sorting line, the mechanical hand and the feeding tray are used, the mechanical hand grabs the product and places it in the groove of the feeding tray, at this time the controller detects that the distance sensor and the weight sensor on the feeding tray all appear data changes; if the mechanical hand abnormally grabs the product, causes no product to be placed on the feeding tray, the controller detects that the distance sensor and the weight sensor on the feeding tray all do not appear numerical changes, the controller controls the alarm to alarm, reminds manual processing exception.
[0024] Compared with the prior art, the product has the following advantages:
[0025] 1. The utility model discloses a through slot is arranged between the groove for placing product on the feeding tray, and the distance sensor is arranged at the end of the through slot and the edge of the feeding tray, so that the distance sensor can pass through the through slot when there is no product on the feeding tray, and different distance data can be returned when the product is placed at different positions, thereby counting the product on the feeding tray, so that the feeding tray can be accurately counted in terms of product quantity, and the situation that the product quantity on the feeding tray is insufficient due to abnormal product grabbing, thereby affecting subsequent production, is prevented.
[0026] 2. The utility model discloses that the weight sensor is also arranged below the through slot in the feeding tray, and the distance sensor and the weight sensor jointly determine the product quantity on the feeding tray in terms of quality and distance scale, so that the counting of the product quantity on the feeding tray is more accurate, and whether the product quantity on the feeding tray is normal can be judged.
[0027] 3. The utility model discloses that the sensor on the feeding tray is electrically connected with the control system on the product sorting line, so that the sensor data change on the feeding tray is monitored during the process that the product is grabbed and placed on the feeding tray, thereby monitoring the grabbing condition of the product by the mechanical hand, and the abnormal grabbing of the mechanical hand on the sorting line can be found in time.
