Abstract
Description
Technical Field
[0001] This utility model relates to the field of insert processing technology, and more specifically, to an automatic positioning device for an insert feeding table. Background Technology
[0002] Injection molded parts are formed by adding raw materials into an injection molding machine. During the molding process, burrs often occur. Burrs not only affect the appearance of the injection molded parts, but also easily injure workers' arms. Therefore, the burrs of injection molded parts must be trimmed. However, the injection molded inserts need to be positioned before trimming, which is the primary problem to be solved.
[0003] For example, patent announcement number CN210456529U discloses a transfer device for automatic feeding of micro-inserts, including a frame, a suction nozzle device, a suction nozzle device drive mechanism, a vision positioning device, an insert carrier, a carrier drive mechanism, and a controller. The insert carrier has an insert positioning area; the carrier drive mechanism drives the insert carrier to move into the insert placement position or out to the insert gripping position; the controller controls the suction nozzle device drive mechanism so that the suction nozzle structure picks up the insert located at the insert picking position, stops at the vision positioning position for positioning by the vision positioning device, and then places the insert in the insert positioning area of the insert carrier located at the insert placement position; then the controller controls the carrier drive mechanism to drive the insert carrier out to the insert gripping position. However, this device uses multiple suction nozzles to pick up the corresponding inserts separately, resulting in high overall cost, significant limitations, and is not conducive to mass production.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] like Figures 1 to 2 As shown, this utility model discloses an automatic positioning device for an insert feeding platform, including a frame 1. The frame 1 is equipped with a feeding platform 2, which can slide along the central axis of the frame 1 under the drive of a drive assembly 3. The drive assembly 3 includes at least a guide rail 31 fixed to the frame 1, and a guide block 32 adapted to the guide rail 31. The feeding platform 2 is fixed on the guide block 32. The cooperation between the guide block 32 and the guide rail 31 improves the stability of the feeding platform 2's movement, avoids displacement or shifting, and greatly improves accuracy.
[0024] In this preferred embodiment, a bearing seat 33 is also fixedly mounted on the frame 1. A transmission screw 34 is pivotally mounted on the bearing seat 33, and a transmission nut that matches the transmission screw 34 is mounted on the transmission screw 34. The feeding table 2 is fixedly mounted on the transmission nut. The feeding table is moved by the cooperation of the transmission screw 34 and the transmission nut, which utilizes the high precision and stable and reliable characteristics of screw transmission to greatly improve accuracy.
[0025] The feeding platform 2 is provided with limiting components 4 at both ends for buffering and limiting its position. The limiting components 4 include at least a limiting block 41 fixed on the frame 1. A buffer 42 is fixed on the limiting block 41. The buffer 42 can limit and buffer the feeding platform 2 and accurately limit its position.
[0026] The feeding platform 2 is also provided with a carrier plate 5, which can be locked onto the feeding platform 2 by a locking component 6. The carrier plate 5 is also provided with a set of carrier grooves 51 that are adapted to the outer contour of the insert 100.
[0027] Specifically, the locking assembly 6 includes a locking opening 61 on the feeding table 2. A locking member 62 is slidably disposed within the locking opening 61. The locking member 62 has a vertical end 621 and a horizontal end 622. The lower surface of the horizontal end 622 can press against the upper surface of the carrier plate 5. A rectangular groove 63 is also provided on the vertical end 621. A first isosceles triangular block 64 is slidably disposed within the rectangular groove 63. A second isosceles triangular block 65 is fixed on the feeding table 2. The first isosceles triangular block 64 can move towards the second isosceles triangular block 65 and is in close contact with the waist surface of the second isosceles triangular block 65. The above design is ingenious and the layout is reasonable. By having the upper waist surface of the first isosceles triangular block 64 in close contact with the lower waist surface of the second isosceles triangular block, the carrier plate 5 can be accurately pressed onto the feeding table, thereby achieving rapid and stable positioning, improving the yield rate. In addition, the structure is compact, easy to disassemble, replace and maintain, which greatly improves work efficiency and has a wide range of applications.
[0028] In this preferred embodiment, a support block 66 is fixedly mounted on the vertical end 621. The support block 66 has a receiving cavity 67, and a force-applying spring 68 is built into the receiving cavity 67. The other end of the force-applying spring 68 is fixedly connected to a sliding block 69 disposed in the receiving cavity 67. The first isosceles triangular block 64 is fixedly mounted on the sliding block 69. The above-mentioned use of a force-applying spring 68 for reset is simple in structure, convenient in operation, stable and reliable, and greatly improves work efficiency. Two start buttons 11 connected in series are also fixedly mounted on the frame 1.
[0029] The working process of this utility model is briefly described below:
[0030] The robotic arm picks up the carrier plate 5 and places it on the feeding table 2. It presses down on the horizontal end 622, causing the vertical end 621 to move vertically downwards along the locking opening 61. During this movement, the contact area between the lower waist surface of the first isosceles triangle 64 and the upper waist surface of the second isosceles triangle 64 decreases until they no longer contact each other. At this point, the force spring 68 is compressed. Continuing to push the vertical end 621 downwards, the contact area between the upper waist surface of the first isosceles triangle 64 and the lower waist surface of the second isosceles triangle 64 increases until they are in complete contact. At this point, the force spring 68 is in its natural state, and the lower surface of the horizontal end 622 presses against the upper surface of the carrier plate 5.
[0031] After the above positioning is completed, the transmission screw 34 rotates, which can drive the feeding table to move forward to the corresponding position by touching the nut 35.
[0032] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0033] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
