Description

Technical Field

[0001] This utility model belongs to the field of laminator technology, and particularly relates to a laminator housing and a laminator. Background Technology

[0002] To determine the contact closure between the top hot plate and the laminated material or the hot plate, a position detection mechanism needs to be installed on the laminator housing. The transmitter and receiver of the existing position detection mechanism need to be installed on opposite sides of the laminator housing to avoid the high temperature environment inside the housing affecting the position detection mechanism. However, for a dual-cavity laminator, both sides of the middle plate are in a high-temperature environment. Therefore, the existing position detection mechanism is only suitable for single-cavity laminators and not for dual-cavity laminators. Utility Model Content

[0003] The technical problem to be solved by this utility model is: to provide a laminator housing and a laminator, addressing the issue that existing position detection mechanisms are only applicable to single-cavity laminators.

[0004] To address the aforementioned problems, this utility model provides a laminator housing, including a main frame and a position detection mechanism. The main frame has at least one lamination cavity. A light-transmitting plate is provided on one side wall of the lamination cavity along the horizontal direction. The position detection mechanism includes a detection component and a reflection component. The detection component is installed outside the side wall of the lamination cavity along the horizontal direction, and the reflection component is installed inside the other side wall of the lamination cavity along the horizontal direction. The emitting end of the detection component is used to emit detection light, the light-transmitting plate is used to transmit the detection light, the reflection component can reflect the detection light and allow the detection light to pass through the light-transmitting plate, and the receiving end of the detection component is used to receive the detection light.

[0005] As a further improvement to the above technical solution:

[0006] Optionally, the reflective assembly includes a first mounting bracket and a planar reflector. The planar reflector is mounted on the first mounting bracket, which is mounted on the inner wall of the lamination cavity. The planar reflector is capable of reflecting the detection light to the receiving end of the detection assembly.

[0007] Optionally, the reflective assembly includes a second mounting bracket and a corner reflector, the corner reflector being mounted on the second mounting bracket, the second mounting bracket being mounted on the inner sidewall of the lamination cavity, and the corner reflector being able to reflect the detection light to the receiving end of the detection assembly.

[0008] Optionally, the reflective assembly includes a third mounting bracket and a reflective bowl, the reflective bowl being mounted on the third mounting bracket, the third mounting bracket being mounted on the inner wall of the lamination cavity, and the reflective bowl being able to reflect the detection light to the receiving end of the detection assembly.

[0009] Optionally, the reflective assembly further includes a lens mounted at the rim of the reflective bowl, through which the detection light can pass.

[0010] Optionally, the third mounting bracket is provided with a connecting part, which is fixedly connected to the inner wall of the lamination cavity.

[0011] Optionally, the detection component is a photoelectric detection switch.

[0012] Optionally, the main frame includes an upper crossbeam, a lower crossbeam, a left side plate, and a right side plate. The upper crossbeam and the lower crossbeam are opposite each other in the vertical direction. The upper crossbeam is fixed to the top of the left side plate and the right side plate, and the lower crossbeam is fixed to the bottom of the left side plate and the right side plate. The detection component and the reflection component are respectively installed on the left side plate and the other is installed on the right side plate.

[0013] Optionally, the main frame includes an upper crossbeam, a lower crossbeam, a left side plate, a right side plate, and a middle plate. The upper crossbeam and the lower crossbeam are opposite each other in the vertical direction. The upper crossbeam is fixed to the top of the left side plate and the right side plate, and the lower crossbeam is fixed to the bottom of the left side plate and the right side plate. The middle plate is located in the middle of the left side plate and the right side plate, and the top of the middle plate is fixed to the upper crossbeam, and the bottom of the middle plate is fixed to the lower crossbeam. The detection component is installed on the outside of the side wall of the left side plate or the right side plate, and the reflection component is installed on the side wall of the middle plate. A lamination cavity is formed between the left side plate and the middle plate, and a lamination cavity is formed between the right side plate and the middle plate.

[0014] On the other hand, this utility model embodiment provides a laminator, including a lamination mechanism and a laminator housing as described above. The lamination mechanism is installed inside the lamination housing and is used to press the sheet material. When the lamination mechanism presses the sheet material, the detection light is blocked.

[0015] As a further improvement to the above technical solution:

[0016] Optionally, the lamination mechanism includes a hot press plate, a lamination cylinder, and a movable platform. Multiple layers of the hot press plate are stacked at intervals inside the lamination housing, and the movable platform is located at the drive end of the lamination cylinder.

[0017] This utility model provides a laminator housing and laminator, which, compared with the prior art, have at least the following advantages: When laminated sheets are needed, the sheets are first placed in the lamination mechanism, which then lifts the sheets at a first speed to press them together. When the lamination mechanism presses the sheets tightly, the detection light is blocked, and the receiving end of the detection component cannot receive the detection light. At this time, the lamination mechanism is controlled to slowly press the sheets at a second speed, which reduces the impact force on the main frame and thus avoids damage to the sheet material. Since the transmitting and receiving ends of the detection component are both installed on the outer wall of the lamination cavity along the horizontal direction, they are not affected by the high-temperature environment inside the housing, making it suitable not only for single-cavity laminators but also for double-cavity laminators.

[0027] 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.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Please see Figures 1 to 2This utility model provides a housing for a laminator 100, which includes a main frame 110 and a position detection mechanism 120. The main frame 110 has at least one lamination cavity 111. A light-transmitting plate 112 is provided on one side wall of the lamination cavity 111 along the horizontal direction. The position detection mechanism 120 includes a detection component 121 and a reflection component 122. The detection component 121 is installed outside the side wall of the lamination cavity 111 along the horizontal direction, and the reflection component 122 is installed inside the other side wall of the lamination cavity 111 along the horizontal direction. The emitting end of the detection component 121 is used to emit detection light, the light-transmitting plate 112 is used to transmit the detection light, the reflection component 122 can reflect the detection light and pass it through the light-transmitting plate 112, and the receiving end of the detection component 121 is used to receive the detection light.

[0031] When laminated sheets are required, please refer to Figure 1 , Figure 2 as well as Figure 3 First, the board is placed in the laminating mechanism 130. The laminating mechanism 130 lifts the board at a first speed to press it together. When the laminating mechanism 130 presses the board tightly, please refer to... Figure 1 , Figure 2 as well as Figure 4 When the detection light is blocked, the receiving end of the detection component 121 cannot receive the detection light. At this time, the lamination mechanism 130 slowly presses the plate at a second speed, which reduces the impact force on the main frame 110 and avoids damage to the plate. Since both the transmitting and receiving ends of the detection component 121 are installed on the outer wall of the lamination cavity 111 along the horizontal direction, they are not affected by the high temperature environment inside the housing. This makes it suitable not only for single-cavity laminators 100 but also for dual-cavity laminators 100. The reflective component 122 does not contain electronic components and can withstand the high temperature environment inside the housing.

[0032] The controller can be configured to receive signals from the detection component 121 and control the lamination mechanism 130.

[0033] In this embodiment, the substrate is a PCB. The PCB laminator 100 is an important lamination device in the electronic circuit board industry. During operation, to improve production efficiency, the bottom cylinder of the laminator 100 first pushes the laminating plate upward rapidly. When the top hot plate contacts the material or the hot plate, it then pushes slowly until the required pressure is reached. During production, due to the compact structure and limited space of the upper layer of the laminator 100, it is impossible to install a mechanical position detection device, and the starting delay of the mechanical detection device is relatively high. Therefore, it is difficult to determine the contact and closure status between the top hot plate and the laminating material or the hot plate. If the thrust cylinder continues to move upward rapidly at the moment the top hot plate contacts the laminating material, the PCB laminating material will not meet the process requirements, resulting in defects or even waste. Secondly, if the detection device is located inside the press, the press will need to be stopped and cooled down before inspection and maintenance due to the high operating temperature. This will seriously affect the production line efficiency. More importantly, customers have increasingly stringent requirements for the capacity of PCB presses.

[0034] When PCB lamination is required, the PCB is first placed in the lamination mechanism 130. The lamination mechanism 130 lifts the board at a first speed to press the board together. When the lamination mechanism 130 presses the PCB tightly, the detection light is blocked and the receiving end of the detection component 121 cannot receive the detection light. At this time, the lamination mechanism 130 is controlled to press the PCB slowly at a second speed. This can reduce the impact force on the main frame 110 and thus avoid damage to the board.

[0035] In one specific embodiment, the reflective assembly 122 includes a first mounting bracket and a plane reflector. The plane reflector is mounted on the first mounting bracket, which is mounted on the inner sidewall of the lamination cavity 111. The plane reflector is capable of reflecting detection light to the receiving end of the detection assembly 121.

[0036] Since a single plane mirror cannot reflect the detection light in reverse, the transmitting end and receiving end of the detection component 121 need to be installed at different positions along the horizontal direction on the outer wall of one side of the lamination cavity 111. In this embodiment, the plane mirror is parallel to the side wall where the reflection component 122 is installed. The detection light emitted by the transmitting end of the detection component 121 is incident at an angle of 20 to 40 degrees with the normal of the plane mirror. Correspondingly, the detection light reflected by the plane mirror is reflected to the receiving end of the detection component 121 at the same angle as the normal of the plane mirror.

[0037] In another specific embodiment, the reflective assembly 122 includes a second mounting bracket and a corner reflector. The corner reflector is mounted on the second mounting bracket, which is mounted on the inner sidewall of the lamination cavity 111. The corner reflector is capable of reflecting detection light to the receiving end of the detection assembly 121.

[0038] The corner reflector consists of three mutually perpendicular plane mirrors (or metal reflective surfaces), resembling a corner of a cube, with the lines of intersection of the three reflective surfaces perpendicular to each other. Regardless of the direction from which light enters, after being reflected sequentially by the three reflective surfaces, the outgoing light rays are in the exact opposite direction to the incoming light rays. Therefore, the transmitting and receiving ends of the detection assembly 121 can be installed at the same position on one side of the outer wall of the laminating cavity 111.

[0039] In another specific embodiment, please refer to Figure 5 as well as Figure 6 The reflective assembly 122 includes a third mounting bracket 123 and a reflective bowl 124. The reflective bowl 124 is mounted on the third mounting bracket 123, which is mounted on the inner wall of the lamination cavity 111. The reflective bowl 124 can reflect the detection light to the receiving end of the detection assembly 121.

[0040] The reflector bowl 124 is generally concave, and its surface is usually polished or coated to improve reflectivity. Reflector bowls 124 can include ellipsoidal reflector bowls, double parabolic reflector bowls, double ellipsoidal reflector bowls, and biaxial double parabolic reflector bowls. Utilizing the law of reflection, the detection light emitted from the emitting end of the detection component 121 enters through the side wall of the reflector bowl 124, is reflected by the side wall of the reflector bowl 124, and then reflects to the receiving end of the detection component 121.

[0041] In this embodiment, please refer to Figure 5 as well as Figure 6 The reflective assembly 122 also includes a lens 125, which is installed at the rim of the reflective bowl 124, allowing detection light to pass through. The lens 125's installation at the rim of the reflective bowl 124 prevents oil from entering the interior of the bowl, facilitating cleaning and maintenance. The third mounting bracket 123 has a connecting part 126, which can be fixedly connected to the inner wall of the lamination chamber 111. The connecting part 126 can be a screw; when the reflective assembly 122 needs to be installed on the other side of the lamination chamber 111 along the horizontal direction, the screw engages with the screw hole on the inner wall. Of course, it is understood that the connecting part 126 can also use other structures, such as clips or slots, which are not limited here. The detection assembly 121 is a photoelectric detection switch.

[0042] The reflector bowl 124 is a 90-degree concave reflector bowl 124, and the surface of the reflector bowl 124 is coated with a highly reflective metal material such as a separator.

[0043] In a specific embodiment, please refer to Figure 1When the laminator 100 is a single-cavity laminator 100, the main frame 110 includes an upper crossbeam 113, a lower crossbeam 114, a left side plate 115, and a right side plate 116. The upper crossbeam 113 and the lower crossbeam 114 are opposite each other in the vertical direction. The upper crossbeam 113 is fixed to the top of the left side plate 115 and the right side plate 116, and the lower crossbeam 114 is fixed to the bottom of the left side plate 115 and the right side plate 116. The detection component 121 and the reflection component 122 are installed, one of which is installed on the left side plate 115 and the other is installed on the right side plate 116.

[0044] In this embodiment, the detection component 121 is installed on the outer sidewall of the left side panel 115, and the reflection component 122 is installed on the inner sidewall of the right side panel 116. Alternatively, the detection component 121 can be installed on the outer sidewall of the right side panel 116, and the reflection component 122 can be installed on the inner sidewall of the left side panel 115.

[0045] In another specific embodiment, please refer to Figure 2 When the laminator 100 is a dual-cavity laminator 100, the main frame 110 includes an upper crossbeam 113, a lower crossbeam 114, a left side plate 115, a right side plate 116, and a middle plate 117. The upper crossbeam 113 and the lower crossbeam 114 are opposite each other in the vertical direction. The upper crossbeam 113 is fixed to the top of the left side plate 115 and the right side plate 116, and the lower crossbeam 114 is fixed to the bottom of the left side plate 115 and the right side plate 116. The middle plate 117 is located on the left side plate 115. The middle plate 117 is located in the middle of the right side plate 116, and the top of the middle plate 117 is fixed to the upper crossbeam 113, and the bottom of the middle plate 117 is fixed to the lower crossbeam 114. The detection component 121 is installed on the outside of the side wall of the left side plate 115 or the right side plate 116, and the reflection component 122 is installed on the side wall of the middle plate 117. A pressure cavity 111 is formed between the left side plate 115 and the middle plate 117, and a pressure cavity 111 is formed between the right side plate 116 and the middle plate 117.

[0046] In this embodiment, please refer to Figure 2 The detection component 121 and the reflection component 122 are provided in two sets. One set of detection component 121 is installed on the outside of the side wall of the left side plate 115, and the reflection component 122 is installed on the left side wall of the middle plate 117. The other set of detection component 121 is installed on the outside of the side wall of the right side plate 116, and the reflection component 122 is installed on the right side wall of the middle plate 117. The two sets of detection component 121 and reflection component 122 work independently without affecting each other.

[0047] In addition, such as Figures 1 to 2As shown, another embodiment of this utility model provides a laminator 100, which includes a lamination mechanism 130 and a laminator housing as provided in any of the above embodiments. The lamination mechanism 130 is installed inside the lamination housing and is used to press the sheet material. When the lamination mechanism 130 presses the sheet material, the detection light is blocked. The specific structure of the laminator housing is the same as described in the above embodiments. Since this laminator 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0048] In this embodiment, the lamination mechanism 130 includes a hot press plate 131, a lamination cylinder 132, and a movable platform 133. Multiple hot press plates 131 are stacked at intervals inside the lamination housing, and the movable platform 133 is located at the drive end of the lamination cylinder 132.

[0049] Initially, the laminating cylinder 132 has a stroke of 0. The transmitting end of the detection component 121 emits detection light, and the light reflected back by the reflecting component 122 can pass through the gap between the hot press plate 131 and the PCB bonding material. The receiving end of the detection component 121 can sense and receive the detection light reflected back by the reflecting component 122 and is in a conducting state. At this time, the PCB bonding material is not pressed, and the laminator 100 is in the preparation stage before formal operation.

[0050] When the laminator 100 is operating normally, the lamination cylinder 132 at the bottom of the laminator 100 extends. The hot press plate 131 of the laminator 100 and the PCB pressing material move upward with the movable platform 133 and the cylinder plunger until the PCB pressing material completely blocks the light transmission path between the detection component 121 and the reflective component 122. At this time, the reflective component 122 cannot reflect the detection light emitted by the detection component 121 and is in a disconnected state. When the detection component 121 is disconnected, the PCB pressing material is in a compressed state until the cylinder reaches the system set pressure, after which it switches to a pressure-holding state.

[0051] By installing a detection component 121 with light emission and reception functions on the outside of the dual-cavity laminator 100 or the single-cavity laminator 100, and installing a reflective component 122 with internal high temperature and low vacuum inside the laminator 100, the material pressing inside the laminator 100 and the opening and closing status of the laminator 100 can be accurately detected to provide key input signals to the control system. By controlling the lifting speed of the lamination cylinder 132, the impact force on the main frame 110 can be reduced, thereby avoiding damage to the sheet material.

[0052] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
