Description

Technical Field

[0001] This utility model relates to the field of punching technology for display plastic parts, specifically to a punching device for display plastic parts. Background Technology

[0002] Plastic components in a display play an important role in structural support, insulation protection, and optical adjustment. Among them, plastic components that require punching mainly include bezels, brackets, light guide plate frames, circuit board insulating covers, interface protective sleeves, touch screen bonding frames, cooling fan brackets, backlight module brackets, and screen back covers.

[0003] A search revealed a Chinese patent (CN221561627U) that discloses a corner punching device for a display control board. This device, equipped with an inclined air outlet pipe, heating wire, miniature fan, insulation sleeve, deflector, and combination bracket, utilizes hot air directed from the deflector and inclined air outlet pipe to heat the corners of the display control board. This allows for rapid hole drilling after slight softening. Pre-heating before corner punching prevents the control board from cracking due to excessive punching pressure, thus avoiding waste of board resources. However, the punching process generates plastic dust, which tends to adhere to the softened area after heat treatment, reducing product performance. Therefore, we propose a punching device for display plastic parts. Utility Model Content

[0004] The technical problem to be solved by this application is that plastic dust is generated during the punching process, and after heat treatment, the dust will easily adhere to the softened area, resulting in a decrease in product performance.

[0005] To address the aforementioned technical problems, this application provides a punching device for display plastic parts, including a base, an adjustment mechanism, a punching head, and a hot air blower. The hot air blower is detachably mounted on the adjustment mechanism via an installation component. An air intake component is provided at the air inlet of the hot air blower, and a filter screen is provided between the air intake component and the hot air blower. The hot air blower heats the punched area of ​​the display plastic parts, and in conjunction with the air intake component and the filter screen, the air blown out by the hot air blower, carrying dust from the display plastic parts, is filtered and then sucked in, thereby cleaning the dust from the display plastic parts.

[0006] In some embodiments, a grid plate is embedded at the center of the top of the base, and a collection box located at the bottom of the grid plate is inserted into one side of the base.

[0007] In some embodiments, the adjustment mechanism comprises a slide rail, a motor, a lead screw, and a slider. A motor is mounted on one end of the slide rail, and a slider is slidably connected to the outer side of the slide rail.

[0010] In some embodiments, the mounting assembly includes a mounting plate that is semi-circularly attached to both ends of the blower. Side plates are mounted on both sides of the blower, and the side plates are fixed together by threaded fasteners.

[0011] In some embodiments, the mounting assembly further includes a fixing block, a top plate is mounted on one side of the slider in the last adjustment mechanism, the fixing block is mounted at both ends of the top of the top plate, the punch head is mounted at the center of the bottom of the top plate, a plug rod is inserted into the outside of the fixing block, a vertical rod is mounted on the outside of one end of the mounting plate, the vertical rod is located at the lower end of the top plate, penetrates the top plate and is slidably connected to the inside of the fixing block, and a plurality of positioning holes adapted to the size of the plug rod are equidistantly opened on the outside of the vertical rod.

[0012] This utility model has at least the following beneficial effects:

[0013] When the hot air blower heat-treats the perforated area, the air inlet of the blower draws in air, causing the blown-out gas to carry dust into the suction component. After being filtered by the filter, the dust is circulated back into the hot air blower, thus preventing dust from adhering to the softened area and improving product performance. The hot air blower, suction component, and filter are detachably connected, making it easy to replace the filter later.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5This utility model provides a technical solution: a punching device for display plastic parts, including a base 1, an adjustment mechanism 2, a punching head 3, and a hot air blower 5. The hot air blower 5 is detachably mounted on the adjustment mechanism 2 via an installation component 4. A filter screen 7 is provided between the suction component 6 and the hot air blower 5. The hot air blower 5 heats the punched area of ​​the display plastic parts. With the help of the suction component 6 and the filter screen 7, the gas blown out by the hot air blower 5, which contains dust on the display plastic parts, is filtered and then sucked in, thereby cleaning the dust on the display plastic parts.

[0025] A grid plate 101 is embedded in the center of the top of the base 1, and a collection box 102 located at the bottom of the grid plate 101 is inserted into one side of the base 1. The mesh of the grid plate 101 is larger than the waste material after punching, so that the waste material after punching falls through the mesh of the grid plate 101 into the collection box 102 for collection and processing.

[0026] The adjustment mechanism 2 consists of a slide rail 201, a motor 202, a lead screw 203, and a slider 204. The motor 202 is installed at one end of the slide rail 201, and the slider 204 is slidably connected to the outside of the slide rail 201.

The slide rail 201 in the last adjustment mechanism 2 is installed between the sliders 204 in the other two adjustment mechanisms 2. By driving the motor 202 to drive the lead screw 203 to rotate, the slider 204 slides on the outside of the slide rail 201.

[0027] The hot air blower 5 consists of a blower 501, a fan 502, and a heating wire 503. The fan 502 is installed at the upper end of the blower 501, and the heating wire 503 is installed at the lower end of the blower 501. By activating the fan 502 and the heating wire 503, gas enters from the top of the blower 501, is heated by the heating wire 503, and is blown out from the bottom of the blower 501.

[0028] Mounting assembly 4 includes mounting plates 9, which are semi-circular and attached to both ends of the blower 501. Anti-slip pads are attached to the inner side of the mounting plates 9 to increase the frictional resistance between them and the blower 501, thereby securing the blower 501. Side plates 10 are installed on both sides of the blower 501 at both ends, and the side plates 10 are fixed together by threaded fasteners 11, which consist of bolts and nuts. By removing the bolts and nuts, the mounting plates 9 at both ends can be released, allowing the hot air blower 5 to be disassembled separately, thus reducing replacement costs.

[0029] Mounting assembly 4 also includes a fixing block 13. A top plate 8 is mounted on one side of the slider 204 in the last adjustment mechanism 2. The fixing block 13 is mounted on both ends of the top of the top plate 8. The punch head 3 is mounted at the center of the bottom of the top plate 8. A rod 14 is inserted into the outside of the fixing block 13. A vertical rod 12 is mounted on the outside of the mounting plate 9 at one end. The vertical rod 12 is located at the lower end of the top plate 8, passes through the top plate 8, and is slidably connected to the inside of the fixing block 13. Multiple positioning holes 1201 that are adapted to the size of the rod 14 are equidistantly opened on the outside of the vertical rod 12. By inserting the rod 14 into the positioning holes 1201 at different positions, the height of the hot air blower 5 can be adjusted to make it suitable for display plastic parts of different thicknesses.

[0030] In use, by activating the motors 202 in two of the adjustment mechanisms 2, the other two adjustment mechanisms 2 and the last adjustment mechanism 2 can be moved longitudinally. By activating the motors 202 in the other two adjustment mechanisms 2, the last adjustment mechanism 2 can be moved vertically. By activating the motor 202 in the last adjustment mechanism 2, the top plate 8 can be moved laterally, thereby achieving the adjustment of the longitudinal, lateral or vertical position of the punch head 3.

[0031] A suction assembly 6 is installed at the air inlet of the hot air blower 5. The suction assembly 6 consists of a suction hood 601, a connecting pipe 602, and a connecting cover 603. The connecting cover 603 is threaded onto the upper end of the blower 501. The filter screen 7 is located inside the blower 501 and fits snugly against the top of the blower 501. The connecting cover 603 and the blower 501 are threaded together for easy disassembly and replacement of the filter screen 7 individually, reducing replacement costs. The connecting pipe 602 is installed on the top of the connecting cover 603. The bottom end of the connector 602 is connected to a suction hood 601. The suction hood 601 is semi-circular in shape and located outside the blower 501. By covering the outside of the blower 501 with the semi-circular suction hood 601, the gas blown out of the blower 501 can be better drawn in by the suction hood 601. The gas in the suction hood 601 mixed with dust enters the connecting cover 603 through the connecting pipe 602. After the dust is filtered by the filter screen 7, it is circulated back into the blower 501, thereby preventing dust from adhering to the softened area.

[0032] Example 2

[0033] Please see Figure 6 and Figure 7This utility model provides a technical solution: Based on embodiment 1, this utility model provides another technical solution: Cylinders 15 are symmetrically installed on the top of the base 1 and between the adjusting mechanism 2 and the grid plate 101. A slide plate 16 is installed at the output end of the cylinder 15. A clamping plate 17 is provided on the inner side of the slide plate 16. A sliding rod 18 is symmetrically hinged to the outer side of the clamping plate 17. A limiting plate 19 is installed at one end of the sliding rod 18 that passes through the slide plate 16. A limiting spring 20 is elastically connected between the limiting plate 19 and the slide plate 16. An arc-shaped groove is provided on the inner side of the clamping plate 17. By activating the cylinder 15, the slide plate 16, clamping plate 17, and sliding rod 18 are adjusted. 8. The movement of the limiting plate 19 and the limiting spring 20 causes the clamping plate 17 to clamp and fix the display plastic parts in the frame shape. When clamping the triangular display plastic parts (stands), the clamping plate 17 is tilted and fits against the inclined surface of the stand due to the influence of the inclined surface of the stand, thereby fixing the stand. When clamping the circular display plastic parts such as the interface protective sleeve and the cooling fan bracket, the arc-shaped groove on the inner side of the clamping plate 17 makes the clamping plate 17 fit tightly against the circular display plastic parts, preventing the circular display plastic parts from detaching from the clamping plate 17. This achieves clamping and fixing of display plastic parts of different shapes, prevents the display plastic parts from deviating during punching, and increases the stability of punching.
