[0037] The embodiment of the present invention provides a plastic parts automatic assembly device and system, which can solve the technical problems in the related art that the existing technology assembles plastic parts and display screens by manually pressing plastic parts, resulting in low assembly efficiency, poor assembly quality and high labor intensity.

[0038] Figure 1 An automatic plastic parts assembly device provided by an embodiment of the present invention comprises: a machine platform 1, a transmission component 2, a mounting platform 3 and a mounting component 4.

[0039] The conveying component 2 is arranged on the machine 1, and is used to transfer the plastic parts to a preset position. The mounting platform 3 is arranged in front of the conveying component 2, and is used to place the products to be assembled. The mounting component 4 is arranged on one side of the machine 1 and is located above the conveying component 2. The mounting component 4 is used to pick up the plastic parts transferred by the conveying component 2 and move them to above the mounting platform 3, so as to assemble the plastic parts on the products to be assembled.

[0040] The automatic assembly device for plastic parts of the embodiment of the present invention is provided with a machine, a conveying component, an installation platform and an installation component. The conveying component is arranged on the machine and is used to transfer the plastic parts to a preset position. The installation platform is arranged in front of the conveying component and is used to place the product to be assembled. The installation component is arranged on one side of the machine and is located above the conveying component. The installation component is used to pick up the plastic parts transferred by the conveying component and move them above the installation platform to assemble the plastic parts on the product to be assembled. After the product to be assembled is placed on the installation platform, the conveying component automatically transfers the plastic parts to the preset position, and the installation component automatically picks up and moves the plastic parts to assemble with the display screen. There is no need to manually press the plastic parts, thereby improving the assembly efficiency and assembly quality and reducing the labor intensity.

[0041] As an optional implementation, in an embodiment of the invention, see Figure 1As shown, the conveying assembly 2 includes: a straight vibration funnel 21, a circular vibration plate 22 and a straight vibration guide rail 23. The straight vibration funnel 21 is arranged on the machine 1 and is used to store the plastic parts. The circular vibration plate 22 is arranged on the machine 1 and is located below the straight vibration funnel 21, and is used to arrange the plastic parts transmitted by the straight vibration funnel 21. One end of the straight vibration guide rail 23 extends in the horizontal direction to the front of the circular vibration plate 22, and is used to transport the plastic parts arranged by the straight vibration funnel 21 to a preset position. When the straight vibration funnel 21 After vibration, the plastic parts stored inside fall into the circular vibration plate 22. The circular vibration plate 22 vibrates at different frequencies to make the plastic parts line up one by one and move in one direction until the plastic parts move onto the straight vibration guide rail 23. The straight vibration guide rail 23 vibrates to make the plastic parts move forward one by one along its length direction until the plastic parts move to the other end of the straight vibration guide rail 23. The track size of the straight vibration guide rail 23 matches the size of the plastic parts, which is convenient for carrying and transporting the plastic parts.

[0042] As an optional implementation, in an embodiment of the invention, see Figure 1 As shown, the circular vibration plate 22 is provided with an annular spiral track along the circumferential direction for arranging the plastic parts. The plastic parts falling into the circular vibration plate 22 are moved on their paths by vibration and the guidance of the annular spiral track. The vibrating conveying allows the plastic parts to be expanded and discharged evenly at the outlet, so that the plastic parts are evenly expanded and conveyed to the other end of the straight vibration guide rail 23.

[0043] As an optional implementation, in an embodiment of the invention, see Figure 1 As shown, the conveying component 2 also includes: a support table 24 and a rotator 25, the support table 24 is arranged on the machine table 1, the rotator 25 is arranged at the top of the support table 24 and is located at the other end of the straight vibration guide rail 23, the rotator 25 can slide and rotate along the vertical direction of the support table 24, and is used to fix the plastic parts transmitted by the straight vibration guide rail 23. When the plastic parts move to the other end of the straight vibration guide rail 23, that is, the top of the support table 24, the rotator 25 moves upward in the vertical direction of the support table 24 and lifts up the plastic parts, and then the rotator 25 rotates the plastic parts in the set direction, so that the plastic parts face the position to be installed and are fixed.

[0044] As an optional implementation, in an embodiment of the invention, see Figure 1As shown, the mounting assembly 4 includes: a support column 41 and a three-axis motion mechanism 42. The support column 41 is arranged on one side of the machine 1. The three-axis motion mechanism 42 is arranged on the top of the support column 41 and can be moved vertically or horizontally to the top of the rotator 25 and the mounting platform 3. The support column 41 is used to support the three-axis motion mechanism 42. When the rotator 25 rotates and fixes the plastic part, the three-axis motion mechanism 42 moves vertically, i.e. longitudinally, to the top of the rotator 25 to pick up the plastic part, and then moves horizontally, i.e. laterally, to the top of the mounting platform 3 to assemble the plastic part on the product to be assembled. The structure of the three-axis motion mechanism generally includes three axial motion mechanisms, namely, the lateral (X-axis), longitudinal (Y-axis) and height direction (Z-axis). Transmission structures such as linear guides or ball screws, drivers and motors, etc. are often used to achieve precise control of motion in three axial directions, which can ensure the accuracy and stability of motion. It also has the advantages of high precision and fast response.

[0045] As an optional implementation, in an embodiment of the invention, see Figure 1 As shown, the mounting assembly 4 also includes: a presser 43, which is arranged below the three-axis motion mechanism 42 and is used to pick up the plastic part. When the three-axis motion mechanism 42 moves to above the rotator 25, the presser 43 moves downward in the height direction and absorbs the plastic part. The presser 43 follows the three-axis motion mechanism 42 to move above the mounting platform 3, and then the presser 43 moves downward again in the height direction and presses the plastic part down to assemble it onto the product to be assembled.

The controller is a programmable logic controller, and can control the device through digital or analog input and output. When the product to be assembled is placed on the mounting platform 3, the controller controls the straight vibration funnel 21, the circular vibration plate 22 and the straight vibration guide rail 23 of the conveying component 2 to vibrate and transmit the plastic part, controls the rotator 25 to rotate the plastic part, and also controls the three-axis motion mechanism 42 of the mounting component 4 to move and absorb and press the plastic part through the presser 43 to assemble the plastic part to the product to be assembled.

[0047] As an optional implementation, in an embodiment of the invention, see Figure 1As shown, a sensor is provided in the installation platform 3, and the sensor is connected to the controller for transmitting a signal to the controller when a product to be assembled is placed on the installation platform 3. The sensor is a photoelectric sensor. When the photoelectric sensor senses that a product to be assembled is placed on the installation platform 3, the photoelectric sensor transmits a signal to the controller, so that the controller controls the conveying component 2 and the installation component 4 to transmit and assemble the plastic parts.

[0048] As an optional implementation, in an embodiment of the invention, see Figure 1 As shown, a vacuum suction cup 31 is provided at the bottom of the mounting platform 3 for fixing the product to be assembled. The product to be assembled can be firmly fixed on the mounting platform 3 by the suction force of the vacuum suction cup 31, and its movement can be restricted. In the process of the three-axis motion mechanism 42 pressing the plastic part down to assemble it to the product to be assembled, the product to be assembled can be prevented from moving, thereby improving the accuracy of installation and ensuring the quality of automatic assembly.

[0049] The working principle of the automatic plastic parts assembly device in the embodiment of the present invention is as follows:

[0050] The product to be assembled is placed on the installation platform 3. When the sensor senses that there is a product to be assembled on the installation platform 3, it transmits a signal to the controller. The controller controls the vibration of the direct vibration funnel 21, and the plastic parts fall into the circular vibration plate 22. The circular vibration plate 22 arranges and transmits the plastic parts by vibrating at different frequencies. The direct vibration guide rail 23 vibrates to move the plastic parts forward one by one along their length direction. The rotator 25 rotates and fixes the plastic parts so that the plastic parts face the position to be installed. Then the three-axis motion mechanism 42 moves to the top of the rotator 25, and the plastic parts are picked up by the presser 43. The three-axis motion mechanism 42 moves to the top of the installation platform 3 again, and the plastic parts are pressed down and assembled onto the product to be assembled by the presser 43.
