Description

Technical Field

[0001] The invention relates to the technical field of injection molding processing, in particular to an automatic placing mechanism for feeding thin-sheet injection molding parts. Background Art

[0002] Thin sheet injection molded parts are a type of plastic product produced through the injection molding process, and their notable feature is their thin thickness. Generally speaking, the thickness is usually between 0.1mm-3mm. Compared with traditional injection molded parts, they are thinner in thickness. Thin sheet injection molded parts need to be positioned when they are being trimmed. The conventional positioning method is to use a rubber block to contact it so that it can be accurately positioned.

[0003] The rubber block frequently abuts against the thin sheet. Due to the low thickness of the thin sheet, the frequent contact will cause cutting due to the abutment, resulting in a dent in the rubber block. If the dent is too large, it will affect the placement and positioning of the thin sheet injection molded parts. The existing solution is to replace the block or rotate the block to rotate the area without the dent toward the thin sheet. This method requires regular shutdown inspection operations, which reduces the efficiency of the placement and positioning of the thin sheet injection molded parts. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic placement mechanism for feeding thin-film injection molded parts, so as to solve the problem in the above background technology that the positioning of the existing injection molded parts will cause cutting and wear of the stop block, causing the stop block to be concave and resulting in reduced positioning accuracy.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 4, an automatic placement mechanism for feeding thin-film injection molded parts shown in the figure includes a placement plate 1, a moving port 2 is opened on the placement plate 1, and a moving part 3 is also included, the moving part 3 is in contact with the bottom of the placement plate 1, a docking tube 4 is rotatably installed on the moving part 3, an abutting end 5 is installed in the docking tube 4, a one-way locking member 6 is installed at the bottom of the docking tube 4, an adjusting gear 7 is fixed to the outside of the docking tube 4, an adjusting component 8 is fixed to the bottom of the placement plate 1, and the adjusting gear 7 reciprocates and contacts with the adjusting component 8, so that the docking tube 4 and the abutting end 5 are rotated and adjusted; and a driving member 9 fixed to the bottom of the placement plate 1, and the driving member 9 drives the moving part 3 to move at the bottom of the placement plate 1;

[0029] In this solution, the designed driving member 9 drives the moving part 3 to move back and forth, so that the thin-film injection molded part can be positioned against each other, so that it can be placed accurately. At the same time, during each reciprocating movement, the adjusting gear 7 at the bottom of the docking cylinder 4 will contact the adjusting assembly 8, and the designed one-way locking member 6 can be used to achieve a small angle adjustment rotation of the docking cylinder 4, so that the abutting end 5 rotates accordingly, avoiding the same area from abutting against the thin-film injection molded part for a long time, causing depression;

[0030] It should be noted that: this solution adopts continuous rotation of the abutting end 5, so that the position of its abutment with the thin-film injection molded part is different each time, which can effectively alleviate the depression caused by the abutting end 5, while improving the positioning accuracy during placement and improving the efficiency of injection molded part processing.

[0031] See also Figure 3 and Figure 4 In order to make the movement of the moving part 3 more stable, a moving groove 10 connected to the moving opening 2 is opened at the bottom of the placement plate 1, and the moving part 3 is slidably fitted with the moving groove 10;

[0032] For further information, see Figure 2 - Figure 6 The driving member 9 includes a bidirectional screw rod 11 rotatably mounted on the bottom of the placing plate 1 through a bearing seat, and both ends of the bidirectional screw rod 11 are respectively threadedly connected with the two moving parts 3. A driving motor 12 is fixed to the bottom of the placing plate 1 through a motor frame, and the output end of the driving motor 12 is fixed to one end of the bidirectional screw rod 11 through a coupling;

[0033] The designed drive motor 12 generates power to rotate the bidirectional screw 11, so that the two moving parts 3 connected with the two ends of the bidirectional screw 11 move in the opposite direction synchronously, driving the docking tube 4 and the abutting end 5 to move in the opposite direction synchronously, thereby achieving the abutment of the outer side of the product injection molded part.

[0034] For further information, see Figure 3 - Figure 8The one-way locking member 6 includes a ratchet 13 fixed to the outside of the docking tube 4, a docking rod 14 is fixed to the moving part 3, a baffle 17 is fixed to the docking rod 14, a butt plate 15 abutting against the tooth groove on the ratchet 13 is rotatably mounted on the baffle 17, and an elastic member 16 abutting against the butt plate 15 is fixed to the baffle 17;

[0035] The elastic member 16 includes a spring sheet 18 , which is fixed on the baffle plate 17 and abuts against the abutment plate 15 .

[0036] By abutting the tooth groove of the ratchet 13 with the butt plate 15 in the one-way locking member 6 and cooperating with the spring sheet 18, the butt plate 15 can be stably engaged with the tooth groove, thereby locking the butt sleeve 4 in one direction of rotation. When the other direction rotates in the opposite direction, the butt plate 15 will retreat along the inclined plate of the ratchet 13, thereby achieving one-way locking.

[0037] For further information, see Figure 3 and Figure 8 The adjustment assembly 8 includes a support plate 19 fixed on the placement plate 1, a track plate 20 is fixed on the support plate 19, the track plate 20 is tilted, and a movable tooth portion 21 adapted to the adjustment gear 7 is installed in the track plate 20. When the movable tooth portion 21 is at the outermost end of the track plate 20, it is connected to the adjustment gear 7;

[0038] Among them, the movable tooth portion 21 includes a movable plate 22 that fits with the track plate 20, a tooth block 23 that matches the adjusting gear 7 is fixed to the outside of the movable plate 22, a sliding rod 24 that is fixed to the track plate 20 is slidably inserted in the movable plate 22, and a push spring 25 is sleeved on the outside of the sliding rod 24 for pushing the movable plate 22 to move outward.

[0039] The principle of realizing the rotation adjustment of the docking sleeve 4 by the movement of the moving part 3 is as follows: first, the moving part 3 is driven by the driving member 9 to move along the moving groove 10, thereby driving the abutting end 5 to move in the moving opening 2 accordingly. Each time it moves, the adjusting gear 7 on the outside of the docking sleeve 4 contacts the movable tooth portion 21 in the adjusting assembly 8. When the moving part 3 retreats, the adjusting gear 7 abuts against the movable tooth portion 21, and the one-way locking member 6 locks the docking sleeve 4, so that the adjusting gear 7 is not affected by the abutment of the movable tooth portion 21 and rotates;

[0040] When the moving part 3 abuts against the product thin-film injection molded part, the adjusting gear 7 will abut against the movable tooth part 21, and when it continues to move, it will drive the adjusting gear 7 to rotate, so that the docking tube 4 makes a corresponding turn. After turning, the one-way locking member 6 continues to lock the docking tube 4, thereby driving the abutting end 5 to rotate slightly. Each time the moving part 3 reciprocates, it will drive the abutting end 5 to rotate slightly, so that each time it abuts against the thin-film injection molded part, it is a different area from the last time, avoiding long-term abutment in the same area and the occurrence of depressions, thereby improving the accuracy of the abutment against the thin-film injection molded part.

[0041] It should be noted that each time the movable part 3 retreats, it will contact the tooth block 23. After the contact, it will drive the tooth block 23 and the movable plate 22 to move synchronously along the slide rod 24. The track plate 20 is in an inclined design, and the tooth block 23 will be out of contact with the adjusting gear 7 due to the movement with the track plate 20, thereby not driving the adjusting gear 7 to rotate. When the movable part 3 moves toward the product, it will not be able to move further because the tooth block 23 and the movable plate 22 will abut against the end of the track plate 20. At the same time, the one-way locking member 6 does not affect the rotation, so that the docking tube 4 and the abutting end 5 can rotate at a small angle accordingly.

[0042] In this solution, the operation of accurately placing and positioning the thin film injection molded parts includes the following steps:

[0043] The first step is to move the thin film injection molded part to the placement plate 1 through a conveying device;

[0044] In the second step, the moving part 3 is driven to move by the driving member 9 so that the abutting end 5 abuts against the product sheet injection molded part;

[0045] Step 3: Each time the moving part 3 reciprocates, the adjusting gear 7 on the docking sleeve 4 contacts the adjusting assembly 8, so that the docking sleeve 4 rotates, causing the abutting end 5 to rotate slightly accordingly;

[0046] In the fourth step, after the abutting end 5 contacts the thin film injection molded part for a certain number of times, the personnel can replace the abutting end 5 and replace the abutting end 5 that is concave due to the abutment.

[0047] In this solution, by rotating the abutting end 5, each time the outer side of the abutting end 5 abuts against the product, the area contacted will be different from the last time, thereby reducing the sinking speed of the abutting end 5, thereby reducing its replacement frequency, increasing the number of times the thin film injection molding is placed and positioned, and improving its processing efficiency.

[0048] Example 2: Please refer to Figure 2 This embodiment further explains the first embodiment, and the difference lies in that the installation method of the abutting end 5 is improved to facilitate the adjustment of the contact area between the abutting end 5 and the injection molded part.

[0049] Specifically, the abutting end 5 includes an abutting column 26, in which a docking column 27 threadedly plugged into the docking tube 4 is fixed. In order to avoid damage to the injection molded part caused by abutment with the injection molded part, the abutting column 26 is made of rubber material.

[0050] In the present solution, the abutting column 26 is threadedly connected to the docking tube 4 through the docking column 27, and the installation method is simple. After a certain number of abutments with the injection molded part, the personnel can increase the height of the abutting column 26 by rotating the abutting column 26 and change the contact area with the injection molded part, so that the injection molded part can continue to be abutted, thereby improving the utilization rate of the abutting column 26. There is no need to replace it, and the adjustment time of the abutting column 26 can be reduced by rotating the thread.

[0051] It should also be noted that, see Figure 1 In order to ensure that the rotation speeds of the multiple offset columns 26 are consistent, a marking protrusion 28 is fixed on the top of the offset column 26. The marking protrusion 28 can be used to effectively identify the rotation direction of the offset column 26.
