Description

Technical Field

[0001] The utility model belongs to the technical field of plastic product processing, and particularly relates to a plastic buckle sub-packaging device for electronic components. Background Technique

[0002] A circuit breaker is an important and indispensable device in the power system. It is a device that can automatically disconnect the circuit when abnormal conditions occur in the circuit, such as overload or short circuit, so as to protect the wires and electrical equipment from damage. As a fixing part of the circuit breaker housing, the plastic buckle plays a role in connecting various components and ensuring the integrity of the circuit breaker. If the plastic buckle has defects or falls off, it will directly affect the structural integrity of the circuit breaker, and then reduce the insulation performance of the circuit breaker, leading to potential safety hazards.

[0003] The plastic buckle of the circuit breaker is made by injection molding process. Injection molding is a production process widely used in the manufacturing of plastic products. The basic principle of injection molding is to heat and melt the thermoplastic plastic by an injection molding machine, and then inject the molten plastic into a cooled metal mold under high pressure. After the plastic cools and solidifies in the mold, a product with a specific shape can be formed.

[0004] At present, plastic buckle products are usually produced by an injection molding method of "one mold with multiple cavities". During the production process, when the product is demolded from the mold, the sprue is cut and separated from the plastic buckle, and then the plastic buckle and the sprue freely fall into the buckle receiving box below the mold. Then, the plastic buckle and the sprue are classified and processed by means of timed collection and manual separation.

[0005] However, this production and classification method has the following technical problems:

[0006] First, low efficiency: The slow speed of manual operation has become a bottleneck process in the production process, seriously restricting the production capacity and unable to meet the high daily production capacity requirements.

[0007] Second, classification error: Plastic buckle products are left-right mirror image products, and it is easy to make judgment mistakes during the manual classification process, resulting in the problem of mixed loading of the two products, directly affecting the normal progress of the subsequent processes.

[0008] Third, impurity mixing: During the demolding process of the product, a sprue will be generated and fall into the buckle receiving box together. These sprues need to be manually separated, but due to their small size and the same color as the product, they are likely to be mixed into the product due to operational negligence and flow to the subsequent use links, which may cause the assembly equipment to jam.

The snap receiving box is suitable for mass production and intermittent operation, and can store a certain number of snaps, facilitating flexible handling; the conveyor belt is suitable for continuous production and a production line with a high degree of automation, and can directly convey the snaps to the next process, facilitating docking with other automated equipment. Among them:

[0038] The sub-packaging assembly 2 includes a rectangular back plate. On both sides of one surface of the rectangular back plate, two parallel side plates are provided. At one end of the side plate, a bottom plate inclined towards the suction cup 6 is provided. The included angle between the bottom plate and the rectangular back plate is 45 to 60 degrees; it is used to guide the plastic snaps to slide into the interior of the sub-packaging box 3. The other surface of the rectangular back plate is hinged to the lower end of the robotic arm 1, and the hinge point is arranged at the lower half of the back plate close to the bottom plate, which can make the center of gravity of the sub-packaging assembly 2 closer to the hinge point, helping to reduce the torque during rotation and making the rotation more stable and labor-saving. Between the side plates of the sub-packaging assembly 2, 2n spacer plates parallel to the side plates and with a spacing of 15 to 20 mm are provided; they are used to assist in the precise positioning of the sub-packaging assembly 2 and the snap classification and collection station 4; the sub-packaging assembly 2 includes n + 1 sub-packaging boxes 3, where n is a natural number greater than 0.

[0039] In this embodiment, it further includes a control cabinet for controlling the robotic arm 1 and the flipping cylinder; the sub-packaging assembly 2 includes two sub-packaging boxes 3; in each sub-packaging box 3, two suction cups 6 are provided; the snap classification and collection stations 4 are two.

[0040] In this embodiment Figure 1 and Figure 3 The shown robotic arm 1 is a partial schematic diagram of the lower end of the robotic arm 1; the robotic arm 1 is a horizontal three-axis servo robotic arm or a horizontal five-axis servo robotic arm, and the movement of the robotic arm is controlled by an independent servo motor. Compared with a stepper motor, the servo motor can provide higher precision and faster response.

[0041] Working principle:

[0042] S1, before the injection mold is opened, the operator operates the control cabinet to control the robotic arm 1 to move above the mold cavity. At this time, the sub-packaging assembly 2 is in a vertical state, and the snap receiving plate of the sub-packaging box 3 is below the sub-packaging box 3.

[0043] S2, the operator operates the control cabinet to control the packaging box 3 to enter the mold room to collect the plastic buckle and the material handle; when the injection mold is opened, the suction cup 6 is adsorbed on the material handle, and the plastic buckle connected to the material handle is ejected from the cavity. At the moment of being ejected, the injection mold shears and separates the plastic buckle from the material handle, and under the action of gravity, plastic buckles of different shapes fall from the mold outlet into the corresponding packaging box 3, and the suction cup 6 is still adsorbed on the material handle; in this process, the suction cup 6 utilizes the principle of air pressure difference and creates negative pressure through the vacuum pump, so that the suction cup 6 can firmly adsorb the material handle.

[0044] S3, the operator operates the control cabinet to control the robotic arm 1 to drive the packaging component 2, the plastic buckle and the material handle to move out of the mold room, and move them to the top of the buckle classification and collection station 4. At this time, the intervals between adjacent packaging boxes 3 are aligned with the isolation baffle 8; the packaging component 2 is rotated 90 degrees through the flip cylinder, so that the plastic buckle slides down along the buckle receiving plate of the packaging box 3, and different types of plastic buckles fall into different buckle classification and collection stations 4 respectively, completing the classification and delivery of the plastic buckles.

[0045] During the rotation of the sub-assembly component 2, the center of gravity of the sub-assembly component 2 will make a circular motion around the hinge point between the robot arm 1 and the sub-assembly component 2, that is, the center of rotation. Since the hinge point is set at the lower half of the back plate of the sub-assembly component 2 close to the bottom plate, the center of gravity of the sub-assembly component 2 is closer to the hinge point; when the center of gravity of the sub-assembly component 2 is closer to the hinge point (the center of rotation), the torque required for rotation will be reduced; the energy required to flip the cylinder will also be reduced accordingly; and the center of gravity of the sub-assembly component 2 is close to the center of rotation, which will make the system more stable during rotation, reduce vibration and shaking, and make the control more precise.

[0046] S4, the operator controls the control cabinet to control the robot arm 1 to continue to move to the top of the material box 5, the suction cup 6 is exhausted, and the material is put into the material box 5. One subpackaging operation task is completed. Repeat the above steps until all subpackaging operation tasks are completed.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
