Description

Technical Field

[0001] This utility model relates to the technical field of chip manufacturing and processing equipment, specifically a chip processing line rapid switching device. Background Technology

[0002] Fixtures are essential components in chip manufacturing. After chip processing, the fixtures need to be automatically unloaded, collected, and inspected before being reloaded manually or by mechanical grippers. The unloading and reloading of fixtures consumes a significant amount of production time, reducing chip manufacturing efficiency. Therefore, there is an urgent need for a rapid changeover device for chip manufacturing lines that allows for the recycling of fixtures and improves production efficiency. Utility Model Content

[0003] The present invention aims to provide a rapid switching device for chip processing lines that enables the cyclical use of jigs and improves production efficiency.

[0004] This utility model provides the following basic solution: A rapid switching device for a chip processing line includes a main production line, a return line, a lateral moving component, a longitudinal moving component, and a switching fixture. The return line is located on one side of the main production line. The lateral moving component, the longitudinal moving component, and the switching fixture are located above the main production line and the return line. The longitudinal moving component is slidably connected to the lateral moving component and moves horizontally along the lateral moving component. The switching fixture is slidably connected to the longitudinal moving component and moves vertically along the longitudinal moving component.

[0005] Furthermore, the switching fixture includes pneumatic fingers for holding the fixture, the pneumatic fingers including two pneumatic grippers capable of relative movement; the switching fixture also includes a pressure block and a telescopic drive assembly for driving the pressure block to move vertically, the telescopic drive assembly being fixedly connected to the pressure block, the pressure block being located between the two pneumatic grippers, and the movement direction of the two pneumatic grippers being perpendicular to the movement direction of the pressure block.

[0006] Furthermore, there are multiple pneumatic fingers distributed horizontally, and multiple pressure blocks, with each pressure block corresponding to one of the pneumatic fingers.

[0007] Furthermore, the switching fixture also includes a connecting crossbar, with multiple pressure blocks fixedly connected to the bottom of the connecting crossbar, and the telescopic drive assembly includes two telescopic cylinders, which are fixedly connected to both ends of the connecting crossbar respectively.

[0008] Furthermore, the switching fixture also includes a mounting plate and a guide rod, with the guide rod slidably connected to the mounting plate, and the two telescopic cylinders respectively fixedly connected to the connecting crossbar via the guide rod.

[0009] Furthermore, each of the pressing blocks has a guide section at its bottom.

[0010] Furthermore, the bottom of the opposite side of the pneumatic gripper matches the shape of both ends of the fixture.

[0011] Furthermore, the bottom surface of the pneumatic gripper is inclined towards the fixture from top to bottom along the direction away from the fixture.

[0012] Beneficial effects: 1. The main production line is the main conveying route in the chip processing process, while the return line is the route for conveying the separated fixtures. The main production line and the return line convey in opposite directions. Lateral and longitudinal moving parts are set up to control the movement of the switching fixtures, thereby realizing the clamping and position change of the fixtures. At the end of the return line, a processing mechanism can be set up, such as the image detection and cleaning mechanism. After processing, the fixtures can be reused, thereby realizing the recycling of the fixtures and improving production efficiency.

[0013] 2. During the production process, to control the chip position and achieve precise chip processing, the chip needs to be placed in a fixture for transport. Pneumatic fingers are used to clamp the fixture. During clamping, due to prolonged chip processing, the chip may stick to the fixture. When separating the fixture, the chip may be displaced due to the force of the fixture's movement, interfering with the chip production process. In this solution, a pressure block is used to press against the chip when separating it from the fixture. The pneumatic fingers clamp and move the fixture, thus achieving separation of the fixture without causing chip displacement. This avoids interfering with the chip production process and ensures chip production efficiency.

[0014] 3. The configuration of multiple pneumatic fingers and multiple clamping blocks enables batch separation of chips and fixtures, thereby improving production efficiency. The guide section facilitates the clamping blocks to pass through the fixture and abut against the chip, while the bottom of the pneumatic grippers allows for easy engagement and clamping of the fixture when it is closed.

[0020] The horizontal frame 301 provides an installation position for the horizontal moving part 3. The horizontal motor 303 provides a power source for the movement of the horizontal connecting seat 305. The horizontal lead screw 304, in conjunction with the limiting of the horizontal guide rail 302, causes the horizontal connecting seat 305 to move along the axial direction of the horizontal lead screw 304, i.e., move in the horizontal direction, under the drive of the horizontal motor 303.

[0021] The switching fixture 5 is slidably connected to the longitudinal moving member 4, and the switching fixture 5 moves vertically along the longitudinal moving member 4. Specifically: The longitudinal moving component 4 includes a longitudinal frame 401, a longitudinal guide rail 402, a longitudinal motor 403, a longitudinal lead screw 404, and a longitudinal connecting seat 405. The longitudinal frame 401 is fixedly connected to the transverse connecting seat 305 and is vertically arranged. The longitudinal guide rail 402 is fixedly connected to the longitudinal frame 401, and its length direction is parallel to the length direction of the longitudinal frame 401. The longitudinal motor 403 is mounted on the longitudinal frame 401, and the axial direction of its output shaft is parallel to the length direction of the longitudinal guide rail 402. The longitudinal lead screw 404 is mounted on the longitudinal frame 401, and its output shaft is fixedly connected to the vertical lead screw. The axial direction of the longitudinal lead screw 404 is parallel to the length direction of the longitudinal guide rail 402 and is coaxial with the output shaft of the longitudinal motor 403. The longitudinal lead screw 404 passes through the longitudinal connecting seat 405. The longitudinal connecting seat 405 is slidably connected to the longitudinal guide rail 402 on the side facing the longitudinal frame 401. That is, the longitudinal connecting seat 405 and the longitudinal lead screw 404 are threadedly connected. A longitudinal guide rail groove matching the shape of the longitudinal guide rail 402 is provided on one side of the longitudinal connecting seat 405. The longitudinal guide rail groove and the longitudinal guide rail 402 are used together.

[0022] In this embodiment, the longitudinal frame 401 and the transverse connecting seat 305 are fixedly connected by screws. The longitudinal guide rail 402 is fixedly connected to the longitudinal frame 401 by screws. The longitudinal lead screw 404 and the output shaft of the longitudinal motor 403 are connected by a coupling. The longitudinal motor 403 is a stepper motor. The structure, installation, and connection with other components of the longitudinal motor 403 are very mature existing technologies and will not be described in detail. The longitudinal lead screw 404 and the longitudinal connecting seat 405 adopt existing lead screw structures, that is, the longitudinal connecting seat 405 is a nut, and the longitudinal lead screw 404 is fixedly connected to the longitudinal frame 401 through a support seat. The structure, use, and installation of the lead screw are very mature existing technologies and will not be described in detail.

[0023] The longitudinal frame 401 provides an installation position for the longitudinal moving part 4. The longitudinal motor 403 provides a power source for the movement of the longitudinal connecting seat 405. The longitudinal lead screw 404, in conjunction with the limiting of the longitudinal guide rail 402, causes the longitudinal connecting seat 405 to move along the axial direction of the longitudinal lead screw 404, i.e., move in the vertical direction, under the drive of the longitudinal motor 403.

[0024] As attached Figure 5 , 6 As shown, the switching fixture 5 includes a mounting plate 501, a guide vertical rod 502, a connecting horizontal rod 503, a pressure block 504, and a telescopic drive assembly 505 for driving the pressure block 504 to move vertically, as well as a pneumatic finger 506 for holding the fixture 6. The switching fixture 5 is located above one end of the return line 2.

[0025] Mounting plate 501 is fixedly connected to longitudinal connecting seat 405. Pneumatic fingers 506 are fixedly connected to mounting plate 501. Multiple pneumatic fingers 506 are distributed horizontally and are all fixedly connected to mounting plate 501. The distribution direction of the pneumatic fingers 506 is parallel to the length direction of return line 2 and main production line 1. Specifically: The pneumatic finger 506 includes two pneumatic grippers that can move relative to each other. The bottom of the opposite side of the pneumatic grippers matches the shape of both ends of the fixture 6. The bottom surface of the pneumatic grippers is inclined towards the fixture 6 from top to bottom along the direction away from the fixture 6.

[0026] In this embodiment, the mounting plate 501 and the longitudinal connecting seat 405 are fixedly connected by screws, and the pneumatic fingers 506 and the mounting plate 501 are fixedly connected by bolts. There are five pneumatic fingers 506, and the distribution direction of the five pneumatic fingers 506 is perpendicular to the sliding direction of the longitudinal moving part 4 and perpendicular to the sliding direction of the switching fixture 5.

[0027] The pneumatic fingers 506 are configured to grip and move the fixture 6, thereby separating the chip from the fixture 6. The pneumatic grippers at the bottom are designed to easily engage the fixture 6 when it is closed, thus gripping the fixture 6.

[0028] The telescopic drive assembly 505 is fixedly connected to the pressure block 504, which is located between two pneumatic grippers. The movement direction of the two pneumatic grippers is perpendicular to the movement direction of the pressure block 504. Specifically: The telescopic drive assembly 505 includes two telescopic cylinders, each fixedly connected to the mounting plate 501. The two cylinders are also fixedly connected to both ends of the connecting crossbar 503. Specifically, the two cylinders are fixedly connected to the connecting crossbar 503 via guide vertical rods 502. The guide vertical rods 502 are slidably connected to the mounting plate 501. A pressure block guide rail is provided on the side of the guide vertical rod 502 facing the mounting plate 501. A guide rail seat is provided on the mounting plate 501, and a pressure block guide rail groove matching the shape of the pressure block guide rail is formed on the side of the guide rail seat facing the pressure block guide rail. The pressure block guide rail and the pressure block guide rail groove cooperate with each other. The length direction of the pressure block guide rail is vertically oriented, and the guide vertical rod 502 moves vertically.

[0029] The connecting crossbar 503 is located between the two pneumatic grippers of the same pneumatic finger 506. Multiple pressure blocks 504 are present, and each pressure block 504 corresponds one-to-one with a pneumatic finger 506. All pressure blocks 504 are fixedly connected to the bottom of the connecting crossbar 503. Each pressure block 504 is n-shaped, with its two free ends away from the connecting crossbar 503. Each pressure block 504 has a guide portion at its bottom, meaning both free ends of the pressure block 504 have guide portions. On opposite sides of the guide portions of the same pressure block 504, the guide portions are inclined from the side closest to the other along the direction from the connecting crossbar 503 towards the free ends. The free ends of the pressure blocks 504 also have notches that match the shape of the chip. These notches are designed by those skilled in the art based on the contact point between the pressure block 504 and the chip, requiring no inventive effort from those skilled in the art.

[0030] In this embodiment, the telescopic cylinder is fixedly connected to the mounting plate 501 by bolts. The telescopic rod of the telescopic cylinder is connected to the guide vertical rod 502 by a flange. The end of the guide vertical rod 502 away from the telescopic rod is fixedly connected to the connecting horizontal rod 503 by bolts. The structure, installation, and movement principle of the telescopic cylinder are very mature existing technologies, and therefore will not be described in detail. The guide vertical rod 502 is fixedly connected to the pressure block guide rail by screws, and the guide rail seat is fixedly connected to the mounting plate 501 by screws. There are five pressure blocks 504, and the ends of all five pressure blocks 504 away from the free end are fixedly connected to the connecting horizontal rod 503 by screws. The guide part and the pressure block 504 are integrally formed.

[0031] Due to prolonged chip processing, the chip may adhere to the fixture 6. During separation from the fixture 6, the chip may experience positional displacement due to the force exerted by the movement of the fixture 6, interfering with the chip production process. The clamping block 504, when separating the chip from the fixture 6, presses against the chip, while the pneumatic fingers 506 grip and move the fixture 6, thus achieving separation without causing chip positional displacement. This avoids interfering with the chip production process and ensures production efficiency. The clamping block guide rail and its groove limit the movement of the guide rod 502, thereby limiting the movement of the clamping block 504. The connecting crossbar 503 provides mounting positions for multiple clamping blocks 504, allowing a small number of telescopic cylinders to drive multiple clamping blocks 504, reducing waste of production resources. The combination of multiple pneumatic fingers 506 and multiple clamping blocks 504 enables batch separation of chips and fixture 6, improving production efficiency. The guide section facilitates the clamping block 504's passage through the fixture 6 and its contact with the chip.

[0032] In this scheme, the main production line 1 is the main conveying route in the chip processing process, and the return line 2 is the route for conveying the separated fixture 6. The conveying directions of the main production line 1 and the return line 2 are opposite. The lateral moving parts 3 and the longitudinal moving parts 4 are set to control the movement of the switching fixture 5, thereby realizing the clamping and position change of the fixture 6. A processing mechanism, such as an image detection and cleaning mechanism, can be set at the end of the return line 2. After processing, it can be reused, thereby realizing the recycling of the fixture 6 and improving production efficiency.

[0033] Meanwhile, during the production process, to control the chip position and achieve precise chip processing, the chip needs to be placed in fixture 6 for transport. The pneumatic fingers 506 clamp the fixture 6. During clamping, due to prolonged chip processing, the chip may stick to the fixture 6. When separating the fixture 6, the chip may be displaced due to the force of the fixture 6's movement, interfering with the chip production process. In this solution, the pressure block 504 presses against the chip when separating it from the fixture 6. The pneumatic fingers 506 clamp and move the fixture 6, thus achieving separation of the fixture 6 without causing chip displacement, thereby avoiding interference with the chip production process and ensuring chip production efficiency.
