Description

Technical Field

[0001] The utility model belongs to the technical field of polyimide plate processing, and particularly relates to a positioning device for slitting polyimide plates. Background Art

[0002] Polyimide sheet is a specialty engineering plastic with excellent comprehensive properties, offering superior thermal stability, mechanical properties, dimensional stability, self-lubricating resistance, and radiation resistance. It boasts sufficient rigidity and a low specific gravity, approximately one-fifth that of steel. It exhibits high strength, low friction coefficient, and low expansion coefficient at high temperatures, with a long-term operating temperature range of ≥280°C and short-term use temperatures exceeding ≥400°C.

[0003] As a high-performance material, polyimide has a wide range of applications in various fields. Different fields and specific applications have different requirements for the size, shape, and specifications of polyimide sheets. For example, in the electronics industry, polyimide sheets may need to be cut into sizes suitable for circuit boards or electronic components; in the aerospace field, sheets may need to be cut into specific shapes and structures to meet requirements such as lightweight and high strength.

[0004] When splitting a sheet, the sides must first be fixed to allow it to be cut into different sizes. The center of each sheet must then be fixed to adjust the perimeter to create different shapes (such as rectangles or circles). However, existing positioning equipment can only fix the sides or the center of the sheet, making the processing of specific sheet shapes cumbersome and inefficient. Utility Model Content

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Please also refer to Figures 1 to 4 The present invention describes a positioning device for slitting polyimide sheets in an embodiment. A positioning device for slitting polyimide sheets comprises a frame 10 having a cavity, an X-axis guide seat 101 disposed in the cavity, two Y-axis guide seats 102, and two movable seats 20. The X-axis guide seat 101 is connected to the inner wall of the cavity in a sliding manner along the Y-axis direction, and the Y-axis guide seat 102 is connected to the inner wall of the cavity in a sliding manner along the X-axis direction. The movable seat 20 comprises a slide 201, a central adsorption portion 202 fixed on the slide 201, and a side adsorption portion 203 fixed on the outer wall of the central adsorption portion 202. The X-axis guide seat 101 passes through the two slides 201 and is slidably adapted to the two slides 201. The Y-axis guide seat 102 corresponds to the slide 201 one by one, passes through the slide 201, and the two are slidably adapted. The X-axis guide seat 101 and the Y-axis guide seat 102 are both detachably connected and fixed to the slide 201.

[0033] Specifically, the movable seat 20 also includes an air extraction part 205, which is an air extraction pump. The air extraction pump has two air paths, one of which connects the air extraction pump with the central adsorption part 202, which is a circular suction cup. The outer wall of the central adsorption part 202 is a hard material, and the part where the central adsorption part 202 contacts the plate is a flexible material. The other air path connects the air extraction pump with the side adsorption part 203, which is a long strip of suction cup. The outer wall of the side adsorption part 203 is a hard material, and the part where the side adsorption part 203 contacts the plate is a flexible material.

[0034] It should be noted that the X-axis guide seat 101 and the Y-axis guide seat 102 are both arranged in a horizontal plane; the X-axis guide seat 101 and the Y-axis guide seat 102 are both fixed to the slide seat 201 by bolts.

[0035] Compared with the prior art, the positioning device for slitting polyimide sheets provided in this embodiment has the following advantages:

[0036] When the center of the plate needs to be fixed, the air extraction unit 205 is activated to completely evacuate the air in the area enclosed by the center adsorption unit 202 and the plate surface, thereby allowing the center adsorption unit 202 to be adsorbed and fixed to the plate surface. When the side of the plate needs to be fixed, the air extraction unit 205 is activated to completely evacuate the air in the area enclosed by the side adsorption unit 203 and the side of the plate, thereby allowing the side adsorption unit 203 to be adsorbed and fixed to the side of the plate. In this way, the positioning device can freely choose to fix the center of the plate or the side of the plate, thereby expanding the scope of application of the positioning device.

[0037] When the position of the slide 201 needs to be moved, the staff needs to remove the bolts first, and then push the slide 201 so that the slide 201 can move along the X-axis guide seat 101 or along the Y-axis guide seat 102; after moving the slide 201 to the desired position, the staff fixes the slide 201 to the X-axis guide seat 101 and the Y-axis guide seat 102 with bolts. At this time, the X-axis guide seat 101 and the Y-axis guide seat 102 will be stuck, so that the slide 201 is in a fixed state.

[0038] When the slide 201 moves along the X-axis guide seat 101 , the slide 201 drives the Y-axis guide seat 102 to move at the same time; when the slide 201 moves along the Y-axis guide seat 102 , the slide 201 drives the X-axis guide seat 101 to move at the same time.

[0039] In some embodiments, see Figure 2 The movable seat 20 also includes a base 204 arranged above the slide 201 and fixedly connected to the central adsorption portion 202. A rotating table 30 is rotatably connected between the base 204 and the slide 201, and the axis of the rotating table 30 is parallel to the vertical direction; a driving motor 2011 is fixed on the slide 201, and the driving motor 2011 is transmission-connected to the rotating table 30, and the driving motor 2011 drives the rotating table 30 to rotate.

[0040] It should be noted that the vertical direction is the Z-axis direction.

[0041] After the driving motor 2011 is started, it drives the rotating platform 30 to rotate, thereby adjusting the direction of the side adsorption portion 203, thereby further improving the application range of the positioning device.

[0042] In some embodiments, see Figure 2 and Figure 3The rotating platform 30 includes a lifting seat 302 and a rotating seat 301 distributed up and down, and also includes a variable pitch system 303 arranged between the rotating seat 301 and the lifting seat 302. The variable pitch system 303 has an extrusion part and an elastic member 3032. The extrusion part is used to squeeze the lifting seat 302 upward, and the elastic member 3032 has a pre-tightening force that causes the lifting seat 302 to move downward.

[0043] The height of the lifting seat 302 is adjusted by adjusting the distance between the rotating seat 301 and the lifting seat 302 , thereby changing the height of the side adsorption portion 203 and the central adsorption portion 202 , thereby changing the fixed height of the plate.

[0044] In some embodiments, see Figure 3 A groove 3011 is provided on the top of the rotating seat 301, and the two grooves 3011 are connected; the pitch changing system 303 includes two extrusion blocks 3031 forming an extrusion part, a bidirectional screw 3033 that rotates around its own central axis and is connected to the two grooves 3011, and a rotating motor 3034 for driving the bidirectional screw 3033 to rotate. The threads at both ends of the bidirectional screw 3033 have opposite rotation directions, and the two extrusion blocks 3031 are respectively screwed to the two ends of the bidirectional screw 3033. The extrusion blocks 3031 are provided with an inclined surface that abuts the lifting seat 302 and a protrusion 30311 that slides with the groove 3011. The axial direction of the bidirectional screw 3033 is parallel to the extension direction of the groove 3011.

[0045] The rotating motor 3034 is started to drive the bidirectional screw 3033 to rotate, and the bidirectional screw 3033 drives the two extrusion blocks 3031 to move closer to or away from each other, thereby changing the contact position between the lifting base 302 and the inclined surface, thereby making the lifting base 302 at different heights.

[0046] In some embodiments, see Figure 3 The lifting seat 302 is spherically hinged with a ball 3021 , and the ball 3021 abuts against the inclined surface.

[0047] There is rolling friction between the lifting seat 302 and the inclined surface, which improves the smoothness of the movement between the lifting seat 302 and the inclined surface.

[0048] In some embodiments, see Figure 1 and Figure 2 A telescopic cover 40 is fixed between the movable seat 20 and the base 204 . The telescopic cover 40 is sleeved on the outer periphery of the rotating table 30 and the driving motor 2011 and is telescopic in length along the vertical direction.

[0049] The telescopic cover 40 protects and isolates waste materials or dust generated during cutting, thereby protecting the rotary table 30 and the driving motor 2011.

[0050] In some embodiments, see Figure 2and Figure 4 A ratchet 50 is fixedly provided on the outer periphery of the rotating table 30, and a pawl 2012 is provided above the slide 201 to be engaged with the ratchet 50; a sliding cavity 2013 is provided on the top wall of the slide 201 in the vertical direction, and a one-way screw 2014 is slidably adapted in the sliding cavity 2013, and the top of the one-way screw 2014 is fixedly connected to the pawl 2012, and a threaded sleeve 2015 is screwed on the outer periphery of the one-way screw 2014, and the threaded sleeve 2015 is rotatably connected to the slide 201 around its own center axis.

[0051] Specifically, a limiting block 2016 is fixedly provided in the sliding cavity 2013 , and a limiting groove 20141 is provided on the outer wall of the one-way screw 2014 along the vertical direction to be slidably adapted to the limiting block 2016 .

[0052] The operator rotates the threaded sleeve 2015 to rotate the one-way screw 2014, thereby moving the pawl 2012 upward or downward. When the pawl 2012 moves upward, it engages with the ratchet 50, preventing the rotating platform 30 from rotating and reducing the load on the drive motor 2011. When the pawl 2012 moves downward, it disengages from the ratchet 50, allowing the rotating platform 30 to rotate.

[0053] In some embodiments, see Figure 2 A support bar 2031 is fixed to the bottom wall of the side adsorption portion 203 , and the support bar 2031 protrudes to the side of the side adsorption portion 203 away from the central adsorption portion 202 .

[0054] Place the edge of the plate on the support bar 2031 first, so that the support bar 2031 supports the plate, making it easier for the staff to fix the plate.

[0055] In some embodiments, see Figure 1 The bottom of the frame 10 is provided with a receiving tray 103 which is detachably connected and fixed to the frame 10. Specifically, the frame 10 and the receiving tray 103 are fixed by bolts.

[0056] The receiving tray 103 is used to receive waste materials generated during the cutting process. After the cutting is completed, the receiving tray 103 can be removed from the frame 10 by removing the bolts, and then the waste materials can be poured out from the receiving tray 103.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
