Description

Technical Field

[0001] This utility model belongs to the field of notebook computer shell processing technology, specifically relating to a jig for hot pressing of notebook computer shells. Background Technology

[0002] The closed lid of a laptop is typically referred to as part A of the laptop casing. Part A consists of a casing surface and sidewalls perpendicularly connected to it. During laptop manufacturing, the connection between the casing surface and the sidewalls requires thermoforming. This thermoforming process usually involves bonding metal parts (such as aluminum alloy or aluminum-magnesium alloy) to plastic parts (such as ABS or PC+ABS) using adhesive (usually acrylic AB structural adhesive).

[0003] In traditional hot press fixtures, the lower mold has a horizontal support platform for holding the laptop casing. After the workpiece is fixed on the lower mold, the upper mold cooperates with the lower mold to clamp the laptop casing workpiece between them for hot pressing. However, traditional hot press fixtures can only hot press the surface of the metal casing, while the sidewalls are perpendicular to the casing surface. Therefore, traditional molds cannot hot press the connection between the casing surface and the sidewalls. Utility Model Content

[0004] In view of the technical problems existing in the prior art, this utility model provides a jig for hot pressing of a notebook shell.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot pressing fixture for a laptop shell is used to fix a laptop shell for hot pressing. The laptop shell includes a metal part and a plastic part. The metal part includes a shell surface and a side wall perpendicularly connected to the shell surface. The fixture includes a lower mold and an upper mold connected above the lower mold by a guide mechanism.

[0007] The lower mold includes a base, an inclined boss disposed on the base and adapted to the metal part for supporting the metal part, a plurality of positioning mechanisms disposed on the inclined boss for fixing the plastic part, a positioning component for positioning the metal part, and a fastening component for locking the position of the metal part.

[0008] The upper mold includes a first template connected to the upper end of the guide mechanism, a drive mechanism disposed on the first template, a second template located below the first template, a pressing block disposed at the lower end of the second template, and a heating rod disposed within the pressing block. The upper end of the first template is connected to the drive mechanism, and the drive mechanism can drive the second template to move towards the lower mold, so that the pressing block can press against the connection position of the outer shell surface and the side wall and the plastic part located below the connection position.

[0009] Furthermore, the base includes a base plate, two support plates vertically connected to the upper end of the base plate and arranged at intervals, and an inclined plate detachably connected to the two support plates. The inclined boss protrudes from the surface of the inclined plate in a direction away from the surface of the inclined plate. One end sidewall of the inclined boss is coplanar with the sidewall of the corresponding end of the inclined plate. The sidewall of the inclined boss coplanar with the inclined plate is defined as a load-bearing sidewall, which is used to support the sidewall.

[0010] Furthermore, the positioning mechanism includes a plurality of positioning grooves disposed on the inclined boss and whose shape is adapted to the plastic part, and at least two positioning pins distributed in each of the positioning grooves. The positioning grooves are distributed at the connection position between the surface of the inclined boss and the bearing sidewall.

[0011] Furthermore, the positioning component includes a plurality of first positioning blocks disposed on the inclined plate and distributed on both sides of the inclined boss, and a plurality of second positioning blocks embedded in the edge of the inclined boss. When the inclined boss carries the metal part, the plurality of first positioning blocks contact the outer sidewall of the sidewall of the metal part, while the second positioning blocks can contact the inner sidewall of the sidewall.

[0012] Furthermore, the fastening assembly includes a plurality of suction cup mounting slots disposed on the surface of the inclined protrusion and arranged at intervals, a plurality of vacuum suction cups installed in the suction cup mounting slots in a corresponding manner, and two rotary fastening mechanisms correspondingly distributed on both sides of the inclined protrusion. Each rotary fastening mechanism includes a fastener capable of reciprocating movement. When the fastener rotates toward the inclined protrusion, it can press against the surface of the housing. When the fastener rotates away from the inclined protrusion, it can release the pressure on the surface of the housing.

[0013] Furthermore, each of the aforementioned rotary fastening mechanisms also includes a rotary cylinder mounted on the inclined plate. The rotary cylinder is detachably connected to a spring-loaded fastener, and the end face of the fastener near the inclined plate is provided with a pressing protrusion extending toward the inclined plate. The rotary cylinder can drive the pressing protrusion to rotate toward or away from the inclined protrusion, so that the pressing protrusion can press and fix the metal part.

[0014] Furthermore, the guiding mechanism includes two guiding components respectively disposed on both sides of the inclined boss. Each guiding component includes a guide rod with one end detachably connected to the base and the other end detachably connected to the first template, and a guide sleeve that fits the guide rod into the guide sleeve, the guide sleeve being detachably connected to the second template.

[0015] Furthermore, the driving mechanism includes a driving cylinder vertically connected to the first template by bolts and two buffers detachably connected to the first template and distributed on both sides of the driving cylinder. The second template is provided with a connecting part connected to the piston rod of the driving cylinder. The anti-collision buffer head of the buffer passes through the first template and approaches the second template.

[0016] Furthermore, the end face of the pressing block near the inclined boss is provided with a pressing groove, which can press against the connection position between the outer shell surface of the metal part and the side wall, and the shape of the pressing groove is adapted to the shape of the corresponding position of the metal part.

[0017] Furthermore, the pressing groove is covered with a soft adhesive layer, and an avoidance groove is provided on the pressing surface of the soft adhesive layer.

[0018] In summary, the beneficial effects of this utility model are as follows: 1. The lower and upper molds cooperate with each other, enabling hot pressing of more parts of the laptop shell, including the shell surface and the side wall connection points, ensuring the integrity of the hot pressing process, making the connection between the metal and plastic parts stronger, and improving the overall quality and performance of the laptop shell. The shape of the pressing groove of the pressing block matches the corresponding position of the metal part, ensuring precise pressing and allowing the plastic part below the connection point to fit more tightly with the connection point. 2. The positioning groove can fit and fix the plastic part, and the inclined design of the inclined boss matches the structure of the laptop shell metal parts, better supporting the metal parts and placing the metal and plastic parts in a more reasonable hot pressing position. 3. The rotary cylinder of the rotating fastening mechanism achieves automated operation, saving manpower and time, reducing labor intensity, and making the hot pressing process more efficient and smooth. 4. The drive mechanism uses a drive cylinder located in the middle of the second template, ensuring uniform pressure transmission, avoiding uneven pressure distribution and skewed pressing blocks, and eliminating the need to consider cylinder synchronization issues, thus improving the quality and efficiency of hot pressing.

Detailed Implementation

[0028] The present invention will be further explained below with reference to specific illustrations.

[0029] like Figure 1 and Figure 2 As shown, the notebook casing 100 (product A) includes a metal part 110 and a plastic part 120. The metal part 110 is preferably made of aluminum. The metal part 110 includes a casing surface 111 and a sidewall 112 that is perpendicularly connected to the casing surface 111.

[0030] like Figure 3 and Figure 4As shown, this utility model provides a hot-pressing fixture for a laptop casing, used to fix a laptop casing 100 for hot-pressing processing. It includes a lower mold 200 and an upper mold 400 connected above the lower mold 200 via a guide mechanism 300. The lower mold 200 includes a base 210, an inclined boss 220 disposed on the base 210 and adapted to support a metal part 110, several positioning mechanisms 230 disposed on the inclined bosses 220 for fixing plastic parts 120, a positioning assembly 240 for positioning the metal part 110, and a fastening assembly 250 for locking the position of the metal part 110. The upper mold 400 includes a first template 410 connected to the upper end of the guide mechanism 300, a drive mechanism 420 disposed on the first template 410, a second template 430 located below the first template 410, a pressing block 440 disposed at the lower end of the second template 430, and a heating rod (not shown in the figure) disposed in the pressing block 440. The upper end of the first template 410 is connected to the drive mechanism 420. The drive mechanism 420 can drive the second template 430 to move up and down along the guide mechanism 300. When the second template 430 moves towards the lower mold 200, the pressing block 440 can press against the connection position of the outer shell surface 111 and the side wall 112 and the plastic part 120 located below the connection position. The lower mold 200 first fixes the plastic part 120. After the metal part 110 is supported on the inclined boss 220, the metal part 110 is essentially tilted on the inclined boss 220, which facilitates the exposure of the connection position between the outer shell surface 111 and the side wall 112. The upper mold 400, guided by the guide component 300, can press down on the outer shell surface 111, the side wall 112, and the plastic part 120 located at the connection position between the two. This allows the fixture to perform hot pressing on more parts of the notebook shell 100, including the connection position between the outer shell surface 111 and the side wall 112, ensuring the integrity of the hot pressing process. This improves the overall quality and performance of the notebook shell 100 and makes the connection between the metal part 110 and the plastic part 120 more secure.

[0031] Please see Figure 5The base 210 includes a base plate 211, two support plates 212 vertically connected to the upper end of the base plate 211 and arranged at intervals, and an inclined plate 213 detachably connected to the two support plates 212. Mounting notches 2110 are provided on both sides of the base plate 211, and the base plate 211 can be fixed to the worktable of the hot press using connecting bolts within the mounting notches 2110. An inclined boss 220 protrudes from the surface of the inclined plate 213 in a direction away from the surface of the inclined plate 213. One end sidewall of the inclined boss 220 is coplanar with the corresponding end sidewall of the inclined plate 213. The coplanar sidewall of the inclined boss 220 and the inclined plate 213 is defined as a load-bearing sidewall 221, which supports the sidewall 112. The tilting plate 213 allows the tilting boss 220 to tilt at a certain angle. This tilting design is compatible with the structure of the metal part 110 of the notebook casing 100, providing better support for the metal part 110 and facilitating the exposure of the correct hot-pressing position for cooperation with the upper mold 400. Because the metal part 110 includes the vertically connected casing surface 111 and sidewall 112, the tilting boss 220 allows the metal part 110 to be positioned more effectively during hot pressing, facilitating the pressure block 440 of the upper mold 400 to press the connection between the casing surface 111 and sidewall 112 of the metal part 110 and the underlying plastic part 120, thus improving the effect and quality of the hot-pressing process. Please refer to [link / reference]. Figure 6 One end of the inclined boss 220 is coplanar with the corresponding end of the inclined plate 213, and this coplanar sidewall is defined as the bearing sidewall 221 for bearing the sidewall 112. This design provides a precise positioning reference for the sidewall 112 of the metal part 110. When the metal part 110 is placed, the sidewall 112 can accurately fit against the bearing sidewall 221, ensuring the positional accuracy of the metal part 110 on the base 210, thereby improving the consistency and accuracy of hot pressing and helping to reduce processing defects caused by positional deviations of the metal part 110.

[0032] The positioning mechanism 230 includes a plurality of positioning grooves 231 disposed on the inclined boss 220 and whose shapes are adapted to the plastic parts 120, and at least two positioning pins 232 distributed in each positioning groove 231. The positioning grooves 231 are located at the connection positions between the surface of the inclined boss 220 and the bearing side wall 221, and the positioning pins 232 are bolted to the inclined plate 213. Before the metal parts 110 are supported, the plastic parts 120 to be hot-pressed are loaded one by one into the positioning grooves 231 with similar shapes, and the positioning pins 232 pass through the plastic parts 120 to stably and firmly position the plastic parts 120 in the positioning grooves 231. After the plastic parts 120 are placed, they can fit tightly against the positioning grooves 231, thereby providing a precise positioning reference for the plastic parts 120, ensuring the positional accuracy of the plastic parts 120 during hot pressing, and helping to improve the quality and consistency of hot pressing. The presence of the locating pin 232 can effectively prevent the plastic part 120 from shifting or shaking, ensuring that the plastic part 120 always maintains the correct position during the hot pressing process, thus improving the stability and reliability of the processing.

[0033] Please continue reading. Figure 5 The positioning component 240 includes a plurality of first positioning blocks 241 disposed on the inclined plate 213 and distributed on both sides of the inclined boss 220, and a plurality of second positioning blocks 242 embedded in the edge of the inclined boss 220. When the inclined boss 220 carries the metal part 110, the plurality of first positioning blocks contact the outer sidewall of the sidewall 112 of the metal part 110, while the second positioning blocks 242 can contact the inner sidewall of the sidewall 112. By having the first positioning blocks 241 distributed on both sides of the inclined boss 220 contact the outer sidewall of the sidewall 112 of the metal part 110, and the second positioning blocks 242 embedded in the edge of the inclined boss 220 contact the inner sidewall of the sidewall 112, the metal part 110 can be accurately positioned from both the inner and outer directions of the sidewall 112. The inner and outer positioning method constrains the metal part 110 on both the inner and outer sides of the sidewall 112, greatly enhancing the positioning stability of the metal part 110 on the inclined boss 220. Even when high pressure is applied during hot pressing, the metal part 110 can maintain a relatively fixed position, ensuring the smooth progress of hot pressing and reducing processing defects caused by displacement of the metal part 110.

[0034] The fastening assembly 250 includes a plurality of suction cup mounting slots 251 spaced apart on the surface of the inclined boss 220, a plurality of vacuum suction cups correspondingly installed in the suction cup mounting slots 251, and two rotary fastening mechanisms 252 correspondingly distributed on both sides of the inclined boss. Each rotary fastening mechanism 252 includes a fastener 2521 capable of reciprocating movement. When the fastener 2521 rotates toward the inclined boss 220, it can press against the outer shell surface 111. When the fastener 2521 rotates away from the inclined boss 220, it can release the pressure on the outer shell surface 111. The installed vacuum suction cups are distributed adjacent to the positioning slots 231 and can adsorb and fix the metal part 110 by negative pressure adsorption. The adsorption force of the vacuum suction cups can help the metal part 110 fit more accurately in the position determined by the positioning slots 231 and the positioning assembly 240. The rotary fastening mechanism 252 can further press against the outer shell surface 111, which, together with the vacuum adsorption method, forms a double guarantee. Even when subjected to large external forces or vibrations during hot pressing, the metal part 110 can be ensured not to shift, thus improving the stability of the metal part 110 during hot pressing.

[0035] Please see Figure 7Each rotary fastening mechanism 252 further includes a rotary cylinder 2522 mounted on the inclined plate 213. The rotary cylinder 2522 can be bolted to a spring-loaded fastener 2521. The end face of the fastener 2521 near the inclined plate 213 has a pressing protrusion 2521A protruding towards the inclined plate 213. The rotary cylinder 2522 can drive the pressing protrusion 2521A to rotate towards or away from the inclined boss 220, so that the pressing protrusion 2521A can press and fix the metal part 110. The rotary cylinder 2522 mounted on the inclined plate 213 can automatically drive the pressing protrusion 2521A to rotate towards or away from the inclined boss 220, realizing the pressing and releasing operation of the metal part 110. Compared with the manual fastening method, the automated operation can greatly save manpower and time and improve production efficiency. Operators no longer need to manually operate each fastener 2521, reducing labor intensity and making the entire hot pressing process more efficient and smooth. The rotary cylinder 2522 can precisely control the pressure applied to the metal part 110 by the holding protrusion 2521A by controlling parameters such as air pressure. This ensures that the metal part 110 experiences moderate pressure during hot pressing, securing it firmly without damaging it or affecting the quality of the hot pressing process due to excessive pressure. Precise pressure control improves the consistency and stability of the hot pressing process, guaranteeing product reliability. Furthermore, the rotary cylinder 2522 is bolted to the side of the inclined plate 213 away from the inclined protrusion 220, and this side is not enclosed, allowing for quick and convenient replacement and repair in case of cylinder 2522 malfunction. Fastener 2521 and retaining protrusion 2521A are preferably made of urethane material, which can effectively buffer pressure and avoid direct hard damage to the surface of metal part 110.

[0036] The guiding mechanism 300 includes two guiding components 300 respectively located on both sides of the inclined boss 220. Each guiding component 300 includes a guide rod 310 with one end screwed to the base 210 and the other end screwed to the first template 410, and a guide sleeve 320 that fits the guide rod 310 into the guide sleeve. The guide sleeve 320 is bolted to the second template 430. The cooperation between the guide rod 310 and the guide sleeve 320 provides precise guidance for the movement of the upper mold 400. During the hot pressing process, the upper mold 400 needs to move up and down in a specific direction to accurately press against the notebook casing 100 workpiece.

[0037] Please continue reading. Figure 3 and Figure 4The drive mechanism 420 includes a drive cylinder 421 vertically connected to the first template 410 by bolts, and two buffers 422 detachably connected to the first template 410 and distributed on both sides of the drive cylinder 421. The second template 430 is provided with a connecting part 431 connected to the piston rod of the drive cylinder 421. The connecting part 431 is located in the middle of the second template 430. When the drive mechanism 420 drives the second template 430 to descend for pressing operation, the pressure can be transmitted from the drive cylinder 421 to the entire pressing block 440 in a relatively uniform manner. Because the point of force application is located in the middle of the second template 430, the problem of uneven pressure distribution caused by the offset of the point of force application can be effectively avoided. This makes the force on various parts of the metal part 110 at the connection position between the outer shell surface 111 and the side wall 112 and the plastic part 120 below it more consistent during the hot pressing process, which helps to improve the quality and effect of hot pressing. Furthermore, since one drive cylinder 421 completes the hot pressing, compared to a fixture that uses multiple cylinders working in tandem, there is no need to consider differences in cylinder synchronization or the influence of lever arm, thus preventing the holding block 440 from tilting during the pressing process. The anti-collision buffer head 4220 of the buffer 422 passes through the first template 410 and approaches the second template 430. The buffer 422 is preferably a hydraulic buffer 422. The protective function of the buffer 422 can reduce the failure and damage of fixture components due to frequent impacts, thereby reducing the maintenance cost and replacement frequency of the equipment.

[0038] Please see Figure 8 The pressing block 440 has a pressing groove on its end face near the inclined boss 220. The pressing groove can press against the connection position between the outer shell surface 111 and the side wall 112 of the metal part 110, and the shape of the pressing groove is adapted to the shape of the corresponding position of the metal part 110. The pressing groove is covered with a soft rubber layer 441, and a relief groove 442 is provided on the pressing surface of the soft rubber layer 441. The relief groove 442 is used to avoid the protruding part of the plastic part 120 at the corresponding position. The relief groove 442 can avoid the protruding part of the plastic part 120, and prevent excessive compression or interference during the pressing process. The shape of the pressing groove is adapted to the corresponding position of the metal part 110, ensuring that the pressing block 440 is precisely pressed onto the connection position between the outer surface 111 and the side wall 112 of the metal part 110. This ensures that the metal part 110 and the plastic part 120 are tightly bonded in this critical area, guaranteeing uniform glue distribution, improving the bonding effect, enhancing the structural strength and stability of the notebook shell 100, and improving the quality of hot pressing. The soft overlay layer 441 bears the main friction and pressure during the pressing process, reducing the wear of the hard material of the pressing block 440 itself.

[0039] This fixture has the following features: 1. The lower mold 200 and upper mold 400 work together to perform hot pressing on more parts of the laptop casing 100, including the connection points between the casing surface 111 and the side wall 112. This ensures the integrity of the hot pressing process, making the connection between the metal part 110 and the plastic part 120 more secure, and improving the overall quality and performance of the laptop casing 100. The shape of the pressing groove of the pressing block 440 is adapted to the corresponding position of the metal part 110, ensuring precise pressing and allowing the plastic part 120, located below the connection point, to fit more tightly with the connection point. 2. The positioning groove 231 can fit and fix the plastic part 120. The inclined design of the inclined boss 220 is adapted to the structure of the metal part 110 of the laptop casing 100, which can better support the metal part 110 and place the metal part 110 and the plastic part 120 in a more reasonable hot pressing position. 3. The rotary cylinder 2522 of the rotary fastening mechanism 252 realizes automated operation, saving manpower and time, reducing labor intensity, and making the hot pressing process more efficient and smooth. Fourth, the drive mechanism 420 uses a drive cylinder 421 located in the middle of the second template 430, which ensures uniform pressure transmission, avoids uneven pressure distribution and skewness of the holding block 440, and eliminates the need to consider cylinder synchronization issues, thereby improving the quality and efficiency of hot pressing.

[0040] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
