Description

Technical Field

[0001] The invention relates to the field of ABS board processing, in particular to a fixing device for ABS board processing. Background Art

[0003] After the ABS board is extruded and formed by an extruder, it needs to be cut into sections by a cutting device for subsequent use. The existing Chinese public patent document: CN114619274B discloses a plate fixing device for CNC machine tool processing, which moves the screw rod downward when the gear rotates, and pulls the bottom end of the airbag downward by the first spring.

[0032] The positioning mechanism includes four brackets 7 respectively fixedly mounted on the top of the device base 1, and the four brackets 7 are respectively located on the outside of the four electric telescopic rods 6. A U-shaped frame 8 is fixedly mounted on the top of the bracket 7, and a screw 9 is rotatably mounted on the inner side of the U-shaped frame 8. A gear 10 is fixedly mounted on one end of the screw 9.

A splint 12 is provided on the side of the U-shaped frame 8 away from the bracket 7. The splint 12 is located above the placement plate 2, and the splint 12 is close to the mounting seat 5. Two symmetrically distributed slide bars 13 are fixedly installed on one side of the U-shaped frame 8, a sleeve 14 is slidably installed on the outer side of the slide bar 13, a spring 15 is fixedly installed between the sleeve 14 and the clamping plate 12, and the clamping plate 12 flexibly clamps the ABS plate by utilizing the elasticity of the spring 15, a moving block 16 matched with the screw 9 is fixedly installed between the two sleeves 14, a sleeve plate 17 is fixedly installed on the top of the moving block 16, a positioning plate 18 is fixedly installed on the inner side of the U-shaped frame 8, and a guide rod 19 that slides through the sleeve plate 17 is fixedly installed between the positioning plate 18 and the inner side of the U-shaped frame 8 to provide guidance for the movement of the moving block 16;

[0033] When the electric telescopic rod 6 is started, it can pull the mounting seat 5 to move downward, driving the vacuum suction cup 4 under the mounting box 3 to move downward, and the mounting seat 5 drives the gear 10 to rotate through the rack plate 11, so that the gear 10 can drive the sleeve plate 17 on the moving block 16 to move along the guide rod 19 through the screw rod 9, and the moving block 16 can push the clamping plate 12 to move through the sleeve 14 and the spring 15, so that the four clamping plates 12 can synchronously clamp and position the outer side of the ABS board, and the clamping plate 12 can drive the sliding rod 13 to move along the inner side of the sleeve 14, and compress the spring 15, and use the elasticity of the spring 15 to flexibly clamp the ABS board. When the vacuum suction cup 4 contacts the ABS board, it is ensured that the ABS board is in a suitable processing position, and the vacuum suction cup 4 can accurately adsorb the ABS board, thereby achieving the effect of automatic alignment and improving the convenience of fixing the ABS board.

[0034] The feeding mechanism includes two support plates 20 symmetrically fixedly installed on the top of the device base 1, two symmetrically distributed guide rods 21 are fixedly installed between the two support plates 20, a sleeve seat 22 slidably installed on the outside of the guide rods 21 is fixedly installed at the bottom of the placement plate 2, so that the placement plate 2 can be installed above the two guide rods 21, a moving cylinder 23 located between the two sleeve seats 22 is fixedly installed at the bottom of the placement plate 2, a screw 24 matching the moving cylinder 23 is rotatably installed between the two support plates 20, a drive motor 25 is fixedly installed on the outside of the support plate 20 located on the left side of the device base 1, and the output end of the drive motor 25 passes through the support The plate 20 is fixedly connected to one end of the second screw rod 24. The driving motor 25 can drive the sleeve 22 on the placement plate 2 to move horizontally along the outer side of the second guide rod 21 through the second screw rod 24. A bidirectional screw rod 39 is rotatably installed on the inner side of the installation box 3. A slider 26 is fixedly installed on the top of the vacuum suction cup 4. The two adjacent sliders 26 are respectively matched with the threads at both ends of the bidirectional screw rod 39. The inner side of the slider 26 contacts the inner side of the installation box 3. Rotating the bidirectional screw rod 39 can drive the two sliders 26 to move closer to or away from each other, thereby adjusting the position of the vacuum suction cup 4. An identification component for identifying the moving distance of the slider 26 is also provided on the top of the installation box 3.

[0035] The driving motor 25 can drive the second screw rod 24 to rotate. The two sleeves 22 on the placement plate 2 can make the second screw rod 24 pull the placement plate 2 to move horizontally through the moving cylinder 23 under the limitation of the second guide rod 21, so that it is convenient to adjust the processing position of the ABS board on the placement plate 2, and can process longer ABS boards. In addition, the staff can rotate the bidirectional screw rod 39 so that the bidirectional screw rod 39 drives the two sliders 26 to approach each other along the inner side of the installation box 3, and can adsorb and fix the middle position of the ABS board, so that the staff can process the side of the ABS board, thereby facilitating the processing of ABS boards of more sizes.

[0036] Working principle: First, the staff puts the ABS board to be processed on the placement plate 2 and starts the drive motor 25. The drive motor 25 drives the screw rod 24 to rotate. The two sleeve seats 22 on the placement plate 2 are limited by the guide rod 21, so that the screw rod 24 pulls the placement plate 2 to move horizontally through the moving cylinder 23, and moves the ABS board to the bottom of the four vacuum suction cups 4. Then, the staff starts the electric telescopic rod 6, and the electric telescopic rod 6 pulls the mounting seat 5 to move downward. The two adjacent mounting seats 5 pull the mounting box 3 to move downward, so that the mounting box 3 drives the vacuum suction cup 4 to move downward. At the same time, the mounting seat 5 drives the rack plate 11 to move, so that when the rack plate 11 contacts the gear 10, it drives the gear 10 to rotate, and the gear 10 drives the screw rod 19 to rotate. On the guide rod 11, the rack plate 11 is moved. Under the limitation of the 9 pairs of sleeve plates 17, the screw 9 can drive the moving block 16 to move in the direction of the placement plate 2. The moving block 16 pushes the clamping plate 12 to move synchronously through the sleeve 14 and the spring 15, so that the four clamping plates 12 are synchronously close to the ABS plate. When the clamping plate 12 contacts the ABS plate, the clamping plate 12 pushes the sliding rod 13 to move along the inner side of the sleeve 14, and utilizes the elasticity of the spring 15 to flexibly clamp the ABS plate. When the vacuum suction cup 4 contacts the ABS plate, it ensures that the ABS plate is in a suitable processing position. Finally, the vacuum suction cup 4 accurately adsorbs the ABS plate, thereby achieving the effect of automatic alignment, and can adjust the position of the placement plate 2 according to the length of the ABS plate, so as to facilitate the processing of longer ABS plates and improve the convenience of fixing the ABS plates.

[0037] Example 2: Please refer to Figure 7-Figure 9 , this embodiment further explains the first embodiment. The slag collecting mechanism shown in the figure includes a storage chamber 27 opened inside the placement plate 2. A storage frame 28 is slidably installed on the inner side of the storage chamber 27 to receive the residues generated during the processing of the ABS plate. An opening for limiting the sliding of the storage chamber 27 is opened on the left side of the placement plate 2 to facilitate taking the storage frame 28 out of the storage chamber 27. A magnetic plate 29 matching the left side of the placement plate 2 is fixedly installed on the left side of the storage frame 28 so that the magnetic plate 29 can be fixed on the left side of the placement plate 2. The size of the magnetic plate 29 is larger than the size of the left side of the storage frame 28. A mounting groove is opened on the top of the placement plate 2 to install A plurality of U-shaped support bars 30 are fixedly installed on the inner side of the mounting groove and are used to support the bottom of the ABS board. The gaps between adjacent U-shaped support bars 30 are used to facilitate the downward discharge of residues. A plurality of support bars 31 are fixedly installed on the top of the storage cavity 27 and are evenly distributed. An inner support bar 32 is fixedly installed between the bottom of the U-shaped support bar 30 and the top of the support bar 31 to increase the bearing capacity of the U-shaped support bar 30. A limit baffle 33 is fixedly installed on the top of the placement plate 2 and is located on the left side of the mounting groove. The ABS board contacts the limit baffle 33 to ensure that the four sides of the ABS board and the placement plate 2 remain correspondingly parallel.

[0038] In this embodiment: the staff can place the ABS board on the U-shaped stay 30 on the placement plate 2, and can use the gap between each U-shaped stay 30 to facilitate cutting and processing of the ABS board. In addition, when the staff is processing the ABS board, the residue generated can pass through the gap between each U-shaped stay 30 and enter the storage frame 28, which is convenient for collecting the residue. When cleaning at a later stage, the staff can pull the magnetic suction plate 29 to take the storage frame 28 out of the storage cavity 27 for easy cleaning, thereby achieving the effect of improving the convenience of ABS board processing.

[0039] Example 3: Please refer to Figure 2 and Figure 5 This embodiment further explains other embodiments. The identification component in the figure includes an identification rod 35 fixedly installed on the top of the slider 26. A long groove is provided on the top of the installation box 3 for the identification rod 35 to limit the sliding movement. A scale 36 is provided on the top of the installation box 3 to match the identification rod 35, so that the two vacuum suction cups 4 on the two installation boxes 3 can move the same distance. A turntable 37 located outside the installation box 3 is fixedly installed at both ends of the bidirectional screw 39.

[0040] In this embodiment: the staff can rotate the bidirectional screw 39 through the turntable 37 to improve the convenience of adjusting the bidirectional screw 39, and when the slider 26 moves, it can drive the identification rod 35 to move along the long groove on the installation box 3, and the indicator arrow on the identification rod 35 can move along the top of the scale 36, which is convenient for judging the moving position of the slider 26 and improving the convenience of adjusting the position of the vacuum suction cup 4.

[0041] Example 4: Please refer to Figure 1-Figure 6 This embodiment further illustrates other embodiments. A silicone pad 34 is fixedly installed on the side of the clamping plate 12 in the figure away from the sliding rod 13 to provide protection for the ABS board. A groove for loading ABS board is provided on the top of the support plate 20 located on the right side of the device base 1 to facilitate loading of ABS board. The horizontal height of the support plate 20 located on the left side of the device base 1 is less than the horizontal height of the placement plate 2. A pull plate 38 is fixedly installed on the side of the magnetic plate 29 away from the storage frame 28.

[0042] In this embodiment: the clamping plate 12 can contact the outer side of the ABS board through the silicone pad 34 to prevent excessive pressure from causing bending of the ABS board, and can increase the friction between the clamping plate 12 and the ABS board, so as to facilitate quick clamping of the ABS board. The staff can place the ABS board on the placement plate 2 through the groove on the top of the support plate 20 on the right side of the device base 1. When the ABS board is in the shape of a long strip, continuous loading can be carried out through the groove. When the placement plate 2 moves, it can move to the top of the support plate 20, so as to facilitate the removal of the processed ABS board. The staff can separate the magnetic plate 29 from the left side of the placement plate 2 through the pulling plate 38, so as to facilitate pulling out the storage frame 28.
