Description

Technical Field

[0001] This utility model belongs to the field of PCB manufacturing technology, and in particular relates to a box structure and lamination equipment. Background Technology

[0002] With the rapid development of electronics and technology, the manufacturing process requirements for PCBs (Printed Circuit Boards) are becoming increasingly stringent. Existing multilayer circuit boards generally require vacuuming of the internal cavity of the hot press during the lamination process to protect the materials and prevent defects such as air bubbles from forming during production. Therefore, existing hot presses typically have a front door for sealing. This front door can be opened and closed in a controlled manner in conjunction with an automatic material handling mechanism during production, and when closed, it also provides a certain degree of sealing to the internal cavity of the hot press, facilitating vacuum pump operation.

[0003] To ensure smooth operation of the front door, existing hot presses typically have two rows of machined precision guide rails on both sides for sliding cooperation with the front door. However, while this guide rail configuration enables smooth operation of the front door, it increases the processing and material costs of components, resulting in a higher cost for the hot press. Furthermore, maintenance requires the removal of the front door and guide rails, making the maintenance process cumbersome and time-consuming. Utility Model Content

[0079] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0080] like Figures 1 to 8 As shown, the housing structure for vacuum lamination equipment provided in this embodiment of the present invention includes a main body 1, a first side plate 2, a second side plate 3, a door panel 4, a first guide structure 5, and a second guide structure 6. The first side plate 2 and the second side plate 3 are respectively disposed on opposite sides of the main body 1. The main body 1 is provided with a cavity 11 and an opening communicating with the cavity 11.

[0081] The first side plate 2 is provided with a first guide groove 21, and the second side plate 3 is provided with a second guide groove 31.

[0082] The first guide structure 5 and the second guide structure 6 are installed on the door panel 4. The first guide structure 5 is slidably connected to the first guide groove 21, and the second guide structure 6 is slidably connected to the second guide groove 31, so that the door panel 4 can slide between the closed position and the open position.

[0083] In the closed position, the door panel 4 can seal the opening to close the cavity 11, forming a sealed cavity for subsequent vacuuming operations.

[0084] In the open position, the door panel 4 releases the blockage of the opening and fully opens the cavity 11, making it easy to put in and take out materials (such as hot-pressed materials for circuit boards).

[0085] The housing structure provided in this embodiment of the utility model directly processes the guide grooves onto the first side plate 2 and the second side plate 3, directly utilizing the first side plate 2 and the second side plate 3 as the movement guide for the door panel 4. This eliminates the need for guide rails in the prior art, reducing the material and processing costs of the housing structure. Furthermore, during equipment maintenance, the step of removing the guide rails is unnecessary, making the maintenance process simpler.

[0086] In one embodiment, the first side plate 2 and the second side plate 3 may be made of high-strength metal plates.

[0087] Door panel 4 can be made of lightweight alloy material, and door panel 4 is the only opening for materials to enter and exit the box structure.

[0088] In one embodiment, such as Figures 1 to 3 As shown, the first side plate 2 and the second side plate 3 are respectively disposed on opposite sides of the main body 1 along the first direction x, and the opening is disposed on one side of the cavity 11 along the second direction y.

[0089] Door panel 4 can slide along the third direction z.

[0090] The first direction x, the second direction y, and the third direction z are all perpendicular to each other.

[0091] The door panel 4 is designed to effectively seal the opening by adjusting the positions of the first side panel 2 and the second side panel 3, the orientation of the opening, and the direction of movement of the door panel 4.

[0092] In one embodiment, such as Figures 1 to 3 As shown, the first direction x is the left-right direction of the box structure, the second direction y is the front-back direction of the box structure, and the third direction z is the up-down direction of the box structure. At this time, the movement of the door panel is either rising or falling.

[0093] In one embodiment, the structure of the first guide groove 21 is the same as that of the second guide groove 31.

[0094] Specifically, refer to Figure 6 The first guide groove 21 includes a first vertical groove section and a first inclined groove section connected to the first vertical groove section. The first vertical groove section extends along the third direction z, and the first inclined groove section is inclined toward the cavity 11.

[0095] The second guide groove 31 includes a second vertical groove section 311 and a second inclined groove section 312. The second vertical groove section 311 extends along the third direction z, and the second inclined groove section 312 is inclined toward the cavity 11.

[0096] The first vertical groove segment and the second vertical groove segment 311 are arranged opposite each other along the first direction x, and the first inclined groove segment and the second inclined groove segment 312 are arranged opposite each other along the first direction x.

[0097] At this time, the door panel 4 can be slidably connected between the first vertical groove section and the second vertical groove section 311 via the guide structure, that is, the first guide structure 5 slides in the first vertical groove section and the second guide structure 6 slides in the second vertical groove section 311; or, the door panel 4 can be slidably connected between the first inclined groove section and the second inclined groove section 312 via the guide structure, that is, the first guide structure 5 slides in the second inclined groove section and the second guide structure 6 slides in the second inclined groove section 312; or, the door panel 4 can also move between the vertical groove section and the inclined groove section. When the door panel 4 is slidably connected between the first inclined groove section and the second inclined groove section 312 via the guide structure, that is, when the first guide structure 5 slides in the first inclined groove section and the second guide structure 6 slides in the second inclined groove section 312, the door panel 4 can move closer to or further away from the cavity 11. When the door panel 4 is close to the cavity 11, it can seal the opening, making the cavity 11 sealed; when the door panel 4 is away from the cavity 11, it can release the seal on the opening, making it easier to pick up and put down materials.

[0098] In one embodiment, such as Figure 4 As shown, the first guide structure 5 includes a first base and a first guide member 53. The first base is installed on the door panel 4 to realize the installation of the first guide structure 5 on the door panel 4, and the first guide member 53 is installed on the first base.

[0099] like Figure 5 As shown, the second guide structure 6 includes a second base and a second guide member 63, which enables the second guide structure 6 to be installed on the door panel 4. The second base is installed on the door panel 4, and the second guide member 63 is installed on the second base.

[0100] The first guide member 53 is slidably connected to the first guide groove 21, and the second guide member 63 is slidably connected to the second guide groove 31.

[0101] The sliding connection between the first guide structure 5 and the first guide groove 21 is achieved through the sliding engagement of the first guide member 53 and the first guide groove 21. The sliding connection between the second guide structure 6 and the second guide groove 31 is achieved through the sliding engagement of the second guide member 63 and the second guide groove 31.

[0102] In one embodiment, such as Figure 4 As shown, the first base includes a first fixed seat 51 and a first mounting seat 52. The first fixed seat 51 is mounted on the door panel 4, enabling the first base to be installed on the door panel 4. The first mounting seat 52 is mounted on the side of the first fixed seat 51 near the first side panel 2, forming the first base. The first guide member 53 is mounted on the first mounting seat 52, enabling the first guide member 53 to be installed on the first base.

[0103] The second base includes a second fixed base 61 and a second mounting base 62. The second fixed base 61 is mounted on the door panel 4 to realize the installation of the second base on the door panel 4. The second mounting base 62 is mounted on the side of the second fixed base 61 near the second side panel 3, forming the second base. The second guide member 63 is mounted on the second mounting base 62 to realize the installation of the second guide member 63 on the second base.

[0104] In one embodiment, the first fixing seat 51 and the second fixing seat 61 are made of metal. The first fixing seat 51 and the second fixing seat 61 can be fixed to the door panel 4 by bolts, the first mounting seat 52 can be fixed to the first fixing seat 51 by bolts, and the second mounting seat 52 can be fixed to the second fixing seat 61 by bolts.

[0105] In one embodiment, such as Figure 4 As shown, the first guide member 53 includes a first guide wheel, which is rotatably connected to the first mounting base 52, and the rotation axis of the first guide wheel is parallel to the first direction x.

[0106] The first guide wheel is slidably connected within the first guide groove 21, and the outer wall of the first guide wheel makes rolling contact with the groove wall of the first guide groove 21. This reduces the noise generated by friction between the first guide member 53 and the first guide groove 21.

[0107] like Figure 5 As shown, the second guide member 63 includes a second guide wheel, which is rotatably connected to the second mounting base 62, and the rotation axis of the second guide wheel is parallel to the first direction x.

[0108] The second guide wheel is slidably connected within the second guide groove 31, and the outer wall of the second guide wheel makes rolling contact with the groove wall of the second guide groove 31. This reduces noise generated by friction between the second guide member 63 and the second guide groove 31.

[0109] In one embodiment, both the first guide wheel and the second guide wheel can be made of polyurethane engineering plastic with wear resistance and a low coefficient of friction. Compared with steel bearings, guide wheels made of polyurethane engineering plastic can avoid metal-on-metal collision noise caused by the inertia of the door panel 4 during movement, thereby reducing the decibel level of noise generated during equipment operation and improving the quality of equipment operation.

[0110] Furthermore, the first and second guide wheels have an open, exposed structure, which allows for easy disassembly and installation, and convenient replacement in case of damage.

[0111] In one embodiment, such as Figure 4 and Figure 5 As shown, the first guide structure 5 also includes a first slider (not shown in the figure, but can be referenced). Figure 5 (As shown in the structure of the second slider 64), the first slider is mounted on the first mounting base 52 and slides in cooperation with the first side plate 2.

[0112] The second guide structure 6 also includes a second slider 64, which is mounted on the second mounting base 62 and slides in cooperation with the second side plate 3.

[0113] The first slider and the second slider 64 are provided with lateral guidance for the operation of the door panel 4.

[0114] In one embodiment, the first slider and the second slider 64 may be made of a material with an extremely low coefficient of friction, such as polytetrafluoroethylene, oil-impregnated nylon, etc.

[0115] Furthermore, the first slider and the second slider 64 have an open and exposed structure, which can be easily disassembled and installed, and can be easily replaced when damaged.

[0116] In one embodiment, a first adjusting member (not shown in the figure, but can be referred to) may be provided between the first slider and the first mounting base 52. Figure 5 The structure of the second adjusting member 65 shown in the diagram is illustrated. This first adjusting member is used to adjust the gap between the first slider and the first mounting base 52, thereby adjusting the distance between the first slider and the first side plate 2. When the first slider wears down, causing the gap between the first slider and the first side plate 2 to increase, the gap can be adjusted using the first adjusting member. The first adjusting member can be selected as an adjusting bolt.

[0117] Furthermore, such as Figure 5 As shown, a second adjusting member 65 can be provided between the second slider 64 and the second mounting base 62. This second adjusting member 65 is used to adjust the gap between the second slider 64 and the second mounting base 62, thereby adjusting the distance between the second slider 64 and the second side plate 3. When the gap between the second slider 64 and the second side plate 3 increases due to wear, this gap can be adjusted using the second adjusting member 65. The second adjusting member 65 can be selected as an adjusting bolt.

[0118] In one embodiment, such as Figure 4 and Figure 5 As shown, a first mounting slot 521 is provided on the first mounting base 52, and the first slider is installed in the first mounting slot 521 to realize the installation of the first slider on the first mounting base 52.

[0119] The second mounting base 62 is provided with a second mounting groove 621, and the second slider 64 is mounted in the second mounting groove 621 to realize the installation of the second slider 64 on the second mounting base 62.

[0120] In one embodiment, such as Figure 2 and Figure 3 As shown, there are two first guide grooves 21, which are spaced apart along the third direction z.

[0121] There are two second guide grooves 31, which are spaced apart along the third direction z.

[0122] There are two first guide structures 5, and the two first guide structures 5 are set one-to-one with the two first guide grooves 21.

[0123] There are two second guide structures 6, and the two second guide structures 6 are set one-to-one with the two second guide grooves 31.

[0124] By engaging the two first guide structures 5 with the two first guide grooves 21 and engaging the two second guide structures 6 with the two second guide grooves 31, the movement of the door panel 4 is made smoother.

[0125] In one embodiment, such as Figure 2 and Figure 4 As shown, the enclosure structure also includes a sensing component 7 and a triggering component 8. The sensing component 7 is mounted on the first side panel 2. The triggering component 8 is mounted on the first guide structure 5 and can contact the sensing component 7 when the door panel 4 slides relative to the first guide groove 21 and the second guide groove 31.

[0126] The sensing component 7 is used to obtain the status information of the door panel 4 when the triggering component 8 comes into contact with it.

[0127] The status information of the door panel 4 includes closed position information, open position information, and door panel speed adjustment information. From this, it can be determined whether the door panel 4 has moved to the closed or open position, or whether the movement speed of the door panel 4 needs to be adjusted.

[0128] In one embodiment, such as Figure 2 and Figure 4As shown, the triggering component 8 includes a first trigger 81 and a second trigger 82. The first trigger 81 is mounted on one of the first guide structures 5, and the second trigger 82 is mounted on the other first guide structure 5. Figure 2 In the indicated direction, the first trigger 81 is located above the second trigger 82.

[0129] The sensing component 7 includes a first sensing switch 71, a second sensing switch 72, and a third sensing switch 73, which are sequentially and spaced apart along a third direction z on the first side plate 2. Figure 2 In the indicated direction, the first sensor switch 71 is located above the second sensor switch 72, and the second sensor switch 72 is located above the third sensor switch 73.

[0130] In the closed position, the second trigger 82 can contact the second inductive switch 72, and the second inductive switch 72 can obtain the closed position information.

[0131] Between the closed and open positions, the first trigger 81 can contact the first inductive switch 71, and the first inductive switch 71 can obtain door panel speed adjustment information.

[0132] In the open position, the second trigger 82 can contact the third sensor switch 73, and the third sensor switch 73 can obtain the open position information.

[0133] Therefore, the corresponding status information of the door panel 4 can be obtained through the cooperation between each trigger and each sensor switch.

[0134] In one embodiment, such as Figure 2 and Figure 4 As shown, a fixing strip 22 extending along the third direction z can be provided on the first side plate 2. The fixing strip 22 can be made of aluminum profile and is used to provide a fixing place for each induction switch.

[0135] In one embodiment, such as Figure 2 As shown, the distance between the first sensor switch 71 and the second sensor switch 72 is less than the distance between the second sensor switch 72 and the third sensor switch 73, so as to ensure that when the door panel 4 is between the closed position and the open position, the first trigger 81 can contact the first sensor switch 71.

[0136] In one embodiment, such as Figure 2 and Figure 4As shown, the first trigger 81 and the second trigger 82 have the same structure. Specifically, the first trigger 81 includes a first mounting plate 811 and a first impact plate 812. The first mounting plate 811 is mounted on one of the first guide structures 5, and the first impact plate 812 is mounted on the first mounting plate 811. The first impact plate 812 can contact the first inductive switch 71 so that the first inductive switch 71 can obtain door speed adjustment information when contacted by the first impact plate 812.

[0137] The second trigger 82 includes a second mounting plate and a second impact plate. The second mounting plate is mounted on another first guide structure 5, and the second impact plate is mounted on the second mounting plate. The second impact plate can contact the second inductive switch 72 or the third inductive switch 73, so that the second inductive switch 72 can obtain closed position information when contacted by the second impact plate, and the third inductive switch 73 can obtain open position information when contacted by the second impact plate.

[0138] In one embodiment, such as Figure 2 and Figure 4 As shown, the first impact plate 812 is provided with a first chamfered surface 8121, which can slide in contact with the first sensor switch 71 or the second sensor switch 72 to trigger the first sensor switch 71 or the second sensor switch 72.

[0139] The second impact plate is provided with a second chamfered surface, which can slide into contact with the third sensor switch 73 to trigger the third sensor switch 73.

[0140] In one embodiment, such as Figures 1 to 3 As shown, the housing structure also includes a drive assembly 9, which is installed on the main body 1. The output end of the drive assembly 9 is connected to the door panel 4. The drive assembly 9 is used to drive the door panel 4 to reciprocate between the closed position and the open position to block or release the blockage of the opening.

[0141] In one embodiment, such as Figures 1 to 3 As shown, the drive assembly 9 includes a drive body 91, a drive wheel 92, and a belt 93. The drive body 91 is mounted on the main body 1. The output end of the drive body 91 is connected to the drive wheel 92. The drive body 91 is used to drive the drive wheel 92 to rotate. One end of the belt 93 is wound around the drive wheel 92, and the other end of the belt 93 is connected to the door panel 4.

[0142] Therefore, when the drive body 91 drives the drive wheel 92 to rotate, one end of the belt 93 can continuously wind onto or disengage from the drive wheel 92. When the belt 93 continuously winds onto the drive wheel 92, it can pull the door panel 4 upward, allowing the door panel 4 to move to the closed position. When the belt 93 continuously disengages from the drive wheel 92, the door panel 4 can move downward under its own weight, allowing the door panel 4 to move to the open position.

[0143] In one embodiment, such as Figures 1 to 3 As shown, the drive body 91 includes a drive component 911 and a drive shaft 912. The drive component 911 is mounted on the body 1, and the output end of the drive component 911 is connected to the drive shaft 912. The drive component 911 is used to drive the drive shaft 912 to rotate.

[0144] The drive wheel 92 is mounted on the drive shaft 912 and can rotate synchronously with the drive shaft 912.

[0145] The drive shaft 912 is driven by the drive component 911, causing the drive shaft 912 to rotate. At the same time, the drive wheel 92 rotates synchronously with the drive shaft 912, causing one end of the belt 93 to continuously wind onto or disengage from the drive wheel 92.

[0146] In one embodiment, the drive element 911 is a geared motor.

[0147] The drive wheel 92 can be fixed to the drive shaft 912 by a shrink sleeve, thus realizing the installation of the drive wheel 92 on the drive shaft 912.

[0148] In one embodiment, such as Figures 1 to 3 As shown, the door panel 4 is provided with a connector 41, and the other end of the belt 93 is connected to the connector 41 to indirectly realize the connection between the other end of the belt 93 and the door panel 4.

[0149] Specifically, the connector 41 can be fixed to the door panel 4 with bolts. At the same time, the connector 41 can firmly press the other end of the belt 93 onto the door panel 4.

[0150] In one specific embodiment, such as Figures 1 to 3 As shown, there can be two drive wheels 92 and two belts 93. The two drive wheels 92 are installed at intervals on the drive shaft 912, and the two belts 93 are arranged one-to-one with the two drive wheels 92 to synchronously drive the door panel 4 from multiple positions, making the movement of the door panel 4 more stable.

[0151] At this time, there can be two connectors 41, and the two connectors 41 are set one-to-one with the two belts 93 to realize the connection between each belt 93 and the door panel 4.

[0152] Furthermore, the drive shaft 912 can be extended along the first direction x, and one drive wheel 92 can be installed at the end of the drive shaft 912 near the first side plate 2, and the other drive wheel 92 can be installed at the end of the drive shaft 912 near the second side plate 3, so as to pull the door panel 4 smoothly from both sides of the door panel 4, while avoiding the belt 93 from blocking the cavity 11.

[0153] In one embodiment, such as Figures 1 to 3As shown, the enclosure structure also includes an electronic control system 10, which is installed on the main body 1. The first induction switch 71, the second induction switch 72, the third induction switch 73 and the drive assembly 9 are electrically connected to the electronic control system 10.

[0154] When the door panel 4 is in the state of moving from the open position to the closed position (that is, the closing process of the door panel 4), the electronic control system 10 is used to control the drive assembly 9 to reduce the movement speed of the door panel 4 when the first sensor switch 71 obtains the door panel speed adjustment information, and is also used to control the drive assembly 9 to stop driving the door panel 4 when the second sensor switch 72 obtains the closed position information.

[0155] When the door panel 4 is in the state of moving from the closed position to the open position (that is, the door panel 4 is opening), the electronic control system 10 is used to control the drive assembly 9 to increase the speed of the door panel 4 when the first sensor switch 71 obtains the door panel speed adjustment information, and is also used to control the drive assembly 9 to stop driving the door panel 4 when the third sensor switch 73 obtains the opening position information.

[0156] Through the cooperation between the electronic control system 10 and each sensor switch and drive component 9, the door panel 4 moves in an upward stop, fast / slow speed combination, and downward stop manner during the opening and closing process, thereby improving the efficiency and accuracy of opening and closing the door.

[0157] The working principle of the box structure provided in this embodiment of the utility model (taking the door panel 4 rising when the drive wheel 92 rotates clockwise as an example) is as follows:

[0158] (1) Initial state.

[0159] like Figure 1 As shown, the door panel 4 is at the bottom (i.e., the open position). At this time, the first guide 53 is located in the first guide groove 21, the second guide 63 is located in the second guide groove 31, and the third sensor switch 73 is pressed by the second impact plate. The normally open contact of the third sensor switch 73 is closed, and the normally closed contact is open.

[0160] (2) Door panel closing process.

[0161] like Figure 7 As shown, after receiving the door closing signal from the electronic control system 10, the drive motor drives the drive wheel 92 to rotate clockwise, causing the door panel 4 to move upwards rapidly until the first impact plate triggers the first inductive switch 71, causing the normally open contact of the first inductive switch 71 to close and the normally closed contact to open. At this time, the first inductive switch 71 will obtain the door panel speed adjustment information, and the electronic control system 10 controls the drive motor of the drive assembly 9 to reduce its speed, thereby reducing the movement speed of the door panel 4, causing the door panel 4 to change from a fast state to a slow state.

[0162] Afterwards, door panel 4 moves slowly upwards until each guide component closes inward along its corresponding inclined groove. Once door panel 4 reaches the closed position, the second impact plate triggers the second inductive switch 72, causing its normally open contact to close and its normally closed contact to open. At this time, the second inductive switch 72 receives the information that the door is closed, and the electronic control system 10 controls the drive motor to stop driving the drive wheel 92, causing door panel 4 to stop moving, thus allowing for vacuuming operations.

[0163] (3) Door opening process.

[0164] like Figure 8 As shown, after receiving the door opening signal from the electronic control system 10, the drive motor reverses the drive wheel 92, causing the door panel 4 to move slowly downwards until the first impact plate triggers the first inductive switch 71, causing the normally open contact of the first inductive switch 71 to close and the normally closed contact to open. At this time, the first inductive switch 71 will obtain the door panel speed adjustment information, and the electronic control system 10 will control the drive motor of the drive assembly 9 to increase its speed, thereby increasing the movement speed of the door panel 4 and changing the door panel 4 from a slow state to a fast state.

[0165] Afterwards, door panel 4 moves downwards rapidly until it reaches the open position. The second impact plate triggers the third sensor switch 73, causing its normally open contact to close and its normally closed contact to open. At this time, the third sensor switch 73 will receive the information that the door is in the open position, and the electronic control system 10 will control the drive motor to stop driving the drive wheel 92, thus stopping door panel 4.

[0166] The laminating equipment provided in this embodiment of the present invention includes the box structure provided in the above embodiment.

[0167] According to the laminating equipment of this utility model embodiment, the guide grooves are directly machined onto the first side plate 2 and the second side plate 3 in the box structure. The first side plate 2 and the second side plate 3 are directly used as the movement guide for the door panel 4, eliminating the need for guide rails in the prior art and reducing the material and processing costs of the box structure. In addition, the guide rails do not need to be removed during equipment maintenance, making the maintenance process simpler.

[0168] In one embodiment, the laminating equipment is a hot press.

[0169] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
