Description

Technical Field

[0001] The utility model relates to the technical field of lamp shade injection molding devices, and specifically relates to a weighing tooling. Background Art

[0002] Injection molding is a manufacturing process widely used in plastic processing. It injects plastic heated to a molten state into a pre-designed mold, and then through a cooling and solidification process, finally forms parts or products of the required shape. With its high efficiency, precision and suitability for mass production, this process occupies an important position in many industries such as automotive, electronics, and packaging.

[0003] When injection molding a lamp shade with a large size and a thick thickness, due to the increase in the amount of plastic material required and the extension of the cooling cycle, the complexity of process control significantly increases, which often leads to the occurrence of the "insufficient filling" (i.e., short shot) phenomenon, resulting in quality defects of some products. In traditional practices, usually, manual weighing means are used to screen the injection-molded lamp shades, aiming to eliminate those unqualified products due to insufficient filling. However, this working method is not only time-consuming and laborious, increasing labor costs, but also has low work efficiency in manual operation, and it is difficult to meet the requirements of continuous and automated production pursued by modern manufacturing.

[0023] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0024] As Figures 1 to 3 shown, a weighing tool of the present utility model is used to weigh the injection-molded finished lamp cover. The weighing tool includes: a frame 1, which is arranged on the moving path of the lamp cover; a conveyor belt 2, which is arranged on the frame 1 and is used to receive the lamp cover and transport it; a weighing component 3, which is arranged on the frame 1, the conveyor belt 2 is connected to the weighing component 3, and the weighing component 3 has a plurality of detection pieces 4, and the detection pieces 4 are used to detect the weight of the lamp cover on the conveyor belt 2; a rejection component 5, which is arranged on the side of the conveyor belt 2 and has a movably arranged rejection piece 6, and the rejection piece 6 is in movable abutment with the lamp cover on the conveyor belt 2 and is used to reject the lamp cover with unqualified weight detection.

[0025] The finished lamp cover is taken out from the injection molding machine by a manipulator, and then after cooling and necessary subsequent processing, it finally moves to the position where the frame 1 is located and is smoothly transported to the conveyor belt 2 by the conveying system. At this time, the detection piece 4 performs precise weight detection on the lamp cover on the conveyor belt 2. The lamp covers with qualified weight will be transported by the conveyor belt 2 to the preset position, while the unqualified products with insufficient filling and unqualified weight will be accurately rejected from the conveyor belt 2 by the rejection piece 6. This method of automatically screening injection-molded finished lamp covers not only greatly saves time and labor costs, improves production efficiency, but also ensures the stability of product quality, and can better meet the requirements of modern production lines for continuous and efficient operation.

[0026] Specifically, the weighing component 3 further includes: a support frame 7, the conveyor belt 2 is connected to the support frame 7, the detection components 4 are evenly connected to the support frame 7 and are located below the conveyor belt 2. When the lamp cover is transported onto the conveyor belt 2 on the support frame 7, the detection components 4 arranged below the conveyor belt 2 can accurately calculate the actual weight of the lamp cover according to the pressure change transmitted by the lamp cover; the detection component 4 is preferably a pressure-type MTB sensor. The MTB sensor is a bellows-type weighing sensor, which adopts a stainless steel welded and sealed process, has high precision and high stability, and is suitable for various weighing and force measuring occasions. The MTB sensor can be applied in both pressure and tension modes to meet the needs of different industries. In the pressure application, the sensor generates corresponding electrical signals according to the pressure change to achieve the weighing and force measuring functions.

[0027] Specifically, the rejection component 5 includes: a support platform 8, which is arranged on the frame 1 and is located on the side of the conveyor belt 2; a moving seat 9, which is arranged on the support platform 8, and a plurality of groups of first slide rails 10 are arranged on the moving seat 9, and a rejection component 6 is connected to each group of first slide rails 10; a first driving component 11, a first driving component 11 is arranged on the side of each group of first slide rails 10, the first driving component 11 is electrically connected to the detection component 4, and the output end of each first driving component 11 is respectively connected to a rejection component 6. The first driving component 11 is used to drive the rejection component 6 to move on the first slide rail 10, so that the rejection component 6 can be accurately positioned at the position corresponding to the unqualified lamp cover. The first driving component 11 can be a motor, an oil cylinder or a cylinder.

[0028] In order to allow the moving seat 9 to move, second slide rails 12 are arranged on both sides of the support platform 8, and sliders 13 are arranged on both sides of the moving seat 9. The moving seat 9 is movably arranged on the second slide rails 12 through the sliders 13.

[0029] In order to drive the moving seat 9 to move, the rejection component 5 further includes a second driving component 14, which is arranged on the support platform 8 and the output shaft direction is perpendicular to the output shaft direction of the first driving component 11. The output end of the second driving component 14 is connected to the moving seat 9. The second driving component 14 is used to drive the moving seat 9 to move on the second slide rails 12 through the sliders 13, so as to drive the rejection component 6 on the moving seat 9 to approach or move away from the lamp cover on the conveyor belt 2. The second driving component 14 is preferably a linear guide rail.

[0030] The specific steps for the rejection component 5 to reject the lamp shades with unqualified weight detection on the conveyor belt 2 are as follows: First, when the detection piece 4 identifies that the weight of the lamp shade on the conveyor belt 2 is unqualified, it will transmit this detection information to the first driving piece 11. The first driving piece 11 will then start and drive the rejection piece 6 to move along the first slide rail 10, so that the rejection piece 6 is accurately positioned at the position corresponding to the unqualified lamp shade. Subsequently, the second driving piece 14 starts and drives the moving seat 9 to move along the second slide rail 12 through the slider 13, and further makes the rejection piece 6 on the moving seat 9 approach the lamp shade until the unqualified lamp shade is accurately rejected from the conveyor belt 2.

[0031] In order to receive the lamp shades with unqualified weight detection, a collection piece is also provided on the frame 1. It is arranged below the conveyor belt 2 on the side away from the rejection component 5. When the unqualified lamp shade is pushed off the conveyor belt 2 by the rejection piece 6, due to the action of its own gravity, the lamp shade will naturally fall into the collection piece, so as to effectively collect and isolate the unqualified products.

[0032] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If this specific posture changes, then the directional indication will also change accordingly.
