Description

[0001] This application is a divisional application of Chinese application No. 202110334901.4, filed on March 29, 2021, entitled "Pressure Pressing Device". Technical Field

[0002] This application relates to the field of display technology, specifically to the field of display device assembly, and in particular to a pressing device. Background Technology

[0003] When a relatively soft bezel is installed on a protected component, such as a display device, the bezel is prone to detaching during the positioning and installation process, leading to installation failure. Summary of the Invention

[0004] In view of this, this application provides a pressing device for installing a frame without causing the frame to fall off.

[0005] This application provides a pressing device, the pressing device comprising:

[0006] Material feeding components;

[0007] A first floating member is disposed on the feeding member, and the first floating member floats relative to the feeding member between a first position and a second position along a predetermined direction.

[0008] The first floating member and the feeding member together define the receiving portion of the receiving frame. As the first floating member floats from the first position to the second position, the volume of the receiving portion gradually decreases.

[0009] In existing technologies, the installation of the frame onto the protected component is typically carried out manually with the aid of fixtures, meaning that manual operation is usually involved throughout the entire process. Specifically, the process involves manual installation of the protected component, manual installation of the frame, manual rolling, and manual transfer of the product.

[0010] Although such a process flow is relatively standardized and the proportion of defective products is relatively stable, reducing the proportion of defective products is particularly difficult. This is because the proportion of human factors in the process flow is too large. In other words, it is difficult or inaccurate to analyze the causes of defects based on the actual defects of the products. This leads to a situation where process improvements can only focus too much on the final steps of the process flow, especially the manual rolling process, and secondly on the transfer process.

[0011] However, because the existing technology focuses too much on the manual rolling process, it focuses more on optimizing the frame installation based on the manual rolling process, thus making it difficult to pay attention to the frame installation process itself.

[0012] In fact, the inventors of this application have noticed that the frame falling off during the frame installation process and the need for manual reinstallation of the frame not only objectively reduces production efficiency, but also has an adverse effect on the subsequent rolling process. Therefore, this falling off situation needs to be addressed.

[0013] According to the pressing device provided in this application, a receiving portion defined by a first floating member and a feeding member accommodates a frame, such as a soft frame, which provides sufficient support for the frame, for example, allowing the frame to be slightly over-supported within the receiving portion; and as the volume of the receiving portion decreases with the floating of the first floating member, a portion of the frame is gradually squeezed out of the receiving portion, thereby achieving the installation of the frame.

[0014] As some options, both the feeding member and the first floating member can be formed as plates or generally floor-shaped. For example, the feeding member can be formed as a feeding carrier plate, and the first floating member can be formed as a floating pressure plate, for example.

[0015] The term "floating" as used here should be understood as follows: as the first floating member moves from the first position to the second position, its movement is constantly subject to resistance. This resistance can come from, for example, the restoring force exerted by a flexible element (such as a flexible pad) or an elastic element (such as a spring) due to deformation. Thus, when the first floating member is not in the first position, if it is forced to overcome the aforementioned restoring force and continue moving towards the second position, or if the force maintaining its current position decreases or disappears, the first floating member will return to the first position under the action of the aforementioned restoring force. Such floating, especially floating towards the second position, is particularly beneficial in preventing damage to the protected component from impacts during installation within the frame.

[0016] Preferably, the feeding member includes a main body and a limiting portion formed on the main body, and the first floating member is at least partially disposed on the outer side of the limiting portion;

[0017] The first floating member has a stepped portion formed on the surface away from the main body. The stepped portion is formed on the edge of the surface near the defining portion. The outer side of the defining portion at least partially defines the receiving portion together with the stepped portion.

[0018] Based on the above characteristics, the limiting part, as an example, can be formed as a protrusion protruding relative to the main body. When the shape of the first floating member is frame-shaped, it can be understood as being fitted onto the outer side of the limiting part. Therefore, in this example, the aforementioned first position can be the position where the first floating member contacts the main body, and the second position can be the position of the first floating member after the frame is installed.

[0019] Furthermore, the term "stepped section" as used here should be understood to refer to a portion comprising two intersecting surfaces at an angle. This angle is preferably 90 degrees, and the resulting receiving section also provides better guidance for the frame.

[0020] Preferably, the pressing device further includes:

[0021] A connecting member is disposed on the other side of the feeding member relative to the first floating member and is connected to the first floating member;

[0022] A second floating member is disposed on the side of the first floating member, and the second floating member floats within a predetermined range along the predetermined direction.

[0023] Based on the above features, the adapter member facilitates the application of pressure from the other side of the feeding member, thereby forcing the first floating member to move. Furthermore, the second floating member provides cushioning when the feeding member is mounted on a plane or platform. The adapter member can be, for example, formed in the shape of a plate, i.e., an adapter plate, and the second floating member can be, for example, formed in the shape of a strip-shaped floating block.

[0024] Preferably, the pressing equipment further includes a product positioning table, which is used to position the protected component.

[0025] As an example, when the frame is accommodated in the receiving portion and the feeding member is positioned on the product positioning stage, the frame is positioned in a pre-installation state relative to the protected member. Based on the above characteristics, the protected member refers to a member protected by using a mounting frame. For example, the protected member may be a display device, such as a reflector or monitor, while the frame may be a soft bezel. The product positioning stage provides positioning for the protected member, thus preventing improper frame installation or even installation failure due to deviations in the protected member's position during installation.

[0026] Therefore, the "ready-to-install state" referred to here means that the frame and the protected component are spaced apart from each other in a predetermined direction, and when viewed along the predetermined direction, the outer edge of the frame extends beyond the outer edge of the protected component. Thus, the frame is first pressed against the protected component, and then the portion extending beyond the outer edge of the protected component is further pressed against the side of the protected component by the first floating component along the predetermined direction.

[0027] Preferably, the product positioning platform includes:

[0028] The workbench has a hollowed-out section;

[0029] A placement platform is disposed on the first side of the workbench in the predetermined direction and covers the hollowed-out portion. The placement platform is used to place the protected component on the first side in the predetermined direction.

[0030] A positioning mechanism is disposed on the second side of the worktable in the predetermined direction, corresponding to the hollowed-out portion, and the positioning mechanism is used to position the protected component. Preferably, the positioning mechanism includes:

[0031] The mounting components move along the predetermined direction;

[0032] A first buffer member buffers the movement of the mounting assembly along the predetermined direction;

[0033] Multiple pairs of paired limiting members are disposed on the mounting assembly, with portions of the limiting members exposed on the side of the placement platform closer to the feeding member in the predetermined direction;

[0034] Two of the limiting members in any pair simultaneously abut against the two opposing sides of the protected member and simultaneously release the two opposing sides of the protected member.

[0035] Based on the above characteristics, the positioning mechanism can support the placement platform through the hollowed-out portion of the workbench via the movement of the installation components, and can also effectively position the protected component using paired limiting members. Therefore, the positioning mechanism has a dual function of ensuring stable installation and positioning. In particular, the two limiting members belonging to a pair of limiting members, which abut against the two opposite sides of the protected component, simultaneously position and release, preventing the protected component from shifting during the positioning process and affecting the frame installation.

[0036] Preferably, the installation assembly includes multiple pairs of paired connectors, and two of the limiting members in any pair of limiting members are respectively disposed on the two connectors included in a pair of connectors;

[0037] The connector includes a driving end, and the positioning mechanism further includes a driving component, wherein the two connectors included in any pair of connectors are driven by the driving component.

[0038] Based on the above characteristics, the design of the connectors ensures that the limiting components have different installable positions, which helps to increase the types of protected components that the positioning mechanism can adapt to.

[0039] Preferably, the driving member has a side portion that is inclined relative to the predetermined direction and engages with the driving end, and the end face of the driving end is inclined relative to the predetermined direction in the same way as the side portion of the driving member that engages with the driving end;

[0040] The limiting member is configured to extend or retract relative to the mounting assembly.

[0041] Based on the above features, the driving component and the driving end are engaged in a beveled engagement manner, which helps to ensure the synchronicity of the movement of the aforementioned limiting component; in addition, the limiting component can extend and retract relative to the mounting assembly, so that when the frame is installed on the protected component, the limiting component will not interfere with the installation of the frame.

[0042] Preferably, the product positioning platform includes:

[0043] When the frame is accommodated in the receiving part and the material feeding member is positioned and installed on the product positioning table, a portion of the installation mechanism moves along the predetermined direction to drive the first floating member to float from its current position to the second position.

[0044] The second buffer member buffers the movement of a portion of the mounting mechanism along the predetermined direction before and during the process of the portion of the mounting mechanism driving the first floating member.

[0045] Based on the above characteristics, the movement of the mounting mechanism is buffered, thereby enabling smooth pressure application to the first floating member. This buffering is particularly advantageous in balancing the quality of the frame installation with the cost of the pressing equipment. For example, the power source for the mounting mechanism can be relatively low-cost pneumatics. However, pneumatic drives suffer from drawbacks such as sudden changes in motion and susceptibility to impacts, which pose a threat to the protected components, such as relatively fragile display devices. Here, the use of a second buffer member, such as a hydraulic buffer, effectively overcomes the disadvantages of pneumatic drives, ensuring the quality of the frame installation while also reducing the overall cost of the pressing equipment. Furthermore, the current position here includes the aforementioned first position, as well as positions between the first and second positions.

[0046] Preferably, the product positioning platform includes a pressure-holding mechanism, the pressure holding including a plurality of pressure-holding components disposed on the worktable, the pressure-holding components being used to abut against the side of the protected component on which the frame is mounted;

[0047] The predetermined direction is vertical, and the protected component is formed into a display device.

[0048] Based on the above characteristics, the pressure-holding mechanism ensures that the frame will not detach from the protected component due to springback after pressing, thus improving installation quality. Furthermore, when the predetermined direction is vertical, the difficulty of positioning the protected component is greatly reduced because the protected component can be laid flat, eliminating the need to consider gravity during positioning, which also improves installation quality.

[0073] The pressing equipment provided in this embodiment includes a housing (not labeled in the figure), a product positioning platform 1, a carrier 2, a mounting mechanism 3, a pressure holding mechanism 4, and a control mechanism (not shown in the figure). The following will describe the process in conjunction with... Figures 1 to 11 The connection relationship and working principle of the aforementioned components are described in detail.

[0074] like Figure 1 As shown, Figure 1 A schematic isometric view of the pressing equipment is shown. The aforementioned carrier 2, product positioning platform 1, carrier 2, mounting mechanism 3, pressure holding mechanism 4, and control mechanism can all be housed within the housing. One side of the housing has an opening for installing and removing the aforementioned carrier 2 and for installing and removing the reflector; these processes will be described later. The functions of the safety light curtain 51, start button 52, emergency stop button 53, and handle 54, all located on the housing, will also be described later.

[0075] See Figure 2 , Figure 2 This is a schematic diagram of the front view of the pressing equipment with the housing omitted. (Example) Figure 2 As shown, in this embodiment, the carrier 2 is used to install the flexible frame 6. With the flexible frame 6 installed on the carrier 2, the flexible frame 6 is installed on the product positioning platform 1. A reflector is pre-placed above the product positioning platform 1, and then, with the cooperation of the installation mechanism 3 and the product positioning platform 1, the flexible frame 6 is installed on the reflector. Furthermore, the flexible frame 6 installed on the reflector is pressed down by the pressure-holding mechanism 4 to ensure installation quality.

[0076] Based on the working principle described above, the following will first combine... Figure 3 and Figure 4 Describe the specific structure of vehicle 2, where Figure 3 A schematic diagram of the isometric view of vehicle 2 is shown. Figure 4A schematic bottom view of the carrier 2 is shown. The carrier 2 includes a feeding plate 21 and a floating pressure plate 22. The main body of the feeding plate 21 can be formed into a rectangular plate shape, with four ears formed at its four corners. Four guide pins 26 can be installed on each of these four ears (the guide pins 26 are particularly important for...). Figure 5 and Figure 6 (As shown in the figure), these four guide pins 26 are used to mate with the positioning holes on the placement platform 11 included in the product positioning stage 1 described below.

[0077] In this embodiment, the floating pressure plate 22 can be formed in the shape of a rectangular frame and is mounted on the feeding carrier plate 21. Specifically, as shown... Figure 4 As shown, the lower surface of the feeding carrier plate 21 can be formed with a protrusion having a rectangular outer contour. The floating pressure plate 22 can be sleeved on the outer side of the protrusion, so that when the upper surface of the floating pressure plate 22 contacts the lower surface of the main body of the feeding carrier plate 21, the lower surface of the floating pressure plate 22 can be approximately flush with the lower surface of the protrusion of the feeding carrier plate 21. Figures 5 to 7 ,in Figure 5 This is a top view of vehicle 2. Figure 6 This is a partial view of the sectional view along the AA direction. Figure 7 for Figure 6 See the enlarged view at point B, especially the schematic diagram. Figure 7 For example, the lower surface of the floating pressure plate 22 may slightly extend beyond the lower surface of the protrusion of the feeding plate 21.

[0078] The floating pressure plate 22 can be fitted onto the outer side of the aforementioned protrusion in the following manner. See [reference needed]. Figure 6 A transition plate 25 is provided above the main body of the feeding carrier plate 21. The transition plate 25 is connected to the aforementioned floating pressure plate 22 via floating shafts 24 (e.g., four floating shafts 24) that penetrate the main body of the feeding carrier plate 21. It is understood that when the upper surface of the floating pressure plate 22 contacts the lower surface of the main body of the feeding carrier plate 21, the transition plate 25 has a certain gap from the upper surface of the main body of the feeding carrier plate 21 because the upper ends of the floating shafts 24 protrude relative to the upper surface of the main body of the feeding carrier plate 21. This is precisely... Figure 6 The state of the adapter plate 25 is shown.

[0079] Based on the relative positional relationships of the floating shaft 24, the adapter plate 25, and the floating pressure plate 22 described above, the floating mechanism of the floating shaft 24 will be described in detail below. (See also...) Figure 6 The floating shaft 24 includes Figure 6The shaft member and the reset member (not shown in the figure) disposed on the outer side of the shaft member are shown. This reset member can be located between the lower surface of the adapter plate 25 and the upper surface of the feeding carrier plate 21, for example, the reset member abuts against both of the aforementioned surfaces. Here, the reset member is pressed when the adapter plate 25 is driven to move downward, thereby absorbing the impact on the adapter plate 25 and slowing down the movement speed of the adapter plate 25, thus ensuring that the shaft member and the floating pressure plate 22 connected to the shaft member move smoothly downward relative to the feeding carrier plate 21 at a reduced speed.

[0080] The reset component can be, for example, formed as a helical spring, which can be sleeved on the outer side of the shaft component, with its two ends abutting against the lower surface of the adapter plate 25 and the upper surface of the unloading carrier plate 21, thereby allowing the carrier 2 to... Figure 6 When placed in the orientation shown (i.e., with the adapter plate 25 on top and the feeding carrier plate 21 on the bottom), the adapter plate 25 and the feeding carrier plate 21 can always maintain the same position. Figure 6 The relative positions are shown in the diagram. Furthermore, once the adapter plate 25 is no longer driven during its downward movement, it will eventually return to its original position under the action of the coil spring. Figure 6 The position shown in the figure.

[0081] Further integration Figure 4 , Figure 6 and Figure 7 And see especially Figure 7 In one embodiment, the inner edge of the lower surface of the floating pressure plate 22 may be recessed upward to form a stepped portion 221. Figure 7 The cross-section of the stepped portion 221 is shown in particular, whereby the portion of the aforementioned protrusion of the feeding plate 21 facing the inner surface of the floating pressure plate 22, together with the stepped portion 221, defines a storage slot for the flexible frame 6. Clearly, in this embodiment, the storage slot for the flexible frame 6 is adapted to the shape of the rectangular flexible frame. However, in other embodiments not shown, the shapes of the feeding plate 21, the floating pressure plate 22, and the stepped portion 221 can be adjusted according to the specific shape of the flexible frame 6 to be installed.

[0082] Thus, see further. Figure 7When the floating pressure plate 22 moves downward under the drive of the floating shaft 24, the volume of the storage slot, defined by the stepped portion 221 and the protrusion of the feeding carrier plate 21, gradually decreases. During this process, the soft frame 6 is gradually pushed downward, thereby being further pressed onto the reflector. In the embodiment, when the soft frame 6 is accommodated in the storage slot, it acts as a frame, with the size of the protrusion slightly larger than the inner size of the soft frame 6. This effectively expands and positions the soft frame 6 within the storage slot, and further limits its position via the stepped portion 221 of the floating pressure plate 22, thus preventing the soft frame 6 from falling off and causing installation failure, thereby improving production efficiency. At the same time, as mentioned above, since part of the soft frame 6 is exposed outside the storage slot during the process of the storage slot volume decreasing, the carrier 2 can thus ensure the rapid installation of the soft frame 6, which further contributes to improving production efficiency.

[0083] In addition, see Figure 6 Based on a similar principle, the carrier 2 also includes floating blocks 23 disposed on the main body of the unloading plate 21. For example, two floating blocks 23 can be respectively disposed on the two wide sides of the main body of the unloading plate 21. The floating blocks 23 can be formed in the shape of strips and disposed below the unloading plate 21 via another floating axis. The other floating axis mentioned here is not marked in the figure, but... Figure 6 The diagram shows a shaft member, the upper end of which is embedded in the feeding plate 21, and the lower end connected to the floating block 23. Similarly, a reset member, such as a helical spring sleeved on the outer side of the shaft member, can also be provided on the outer side of the shaft member. This allows the floating block 23 to be located furthest below the main body of the feeding plate 21 via another floating shaft.

[0084] Therefore, the floating block 23 can make initial contact with the placement platform 11 when the vehicle 2 is installed on the placement platform 11. This is particularly helpful in ensuring that the vehicle is installed smoothly, thereby further preventing the soft frame 6 from falling off. It also helps to prevent the vehicle 2 from impacting the reflector already placed on the placement platform 11.

[0085] See further Figure 8 Compared to what was shown previously Figure 2 , Figure 8 Vehicle 2 was further omitted, therefore, Figure 8 The diagram shows an isometric view of the mounting mechanism 3 and the product positioning platform 1. In the following description, [the following will be combined with...] Figures 8 to 11 The structure and working principle of the product positioning platform 1 are explained.

[0086] like Figure 8As shown, in this embodiment, the product positioning platform 1 is used to position and place the reflector. It may include a workbench 10, a placement platform 11, and a positioning mechanism 12. The placement platform 11 is positioned above the workbench 10 and has positioning holes. The number of these positioning holes can be the same as the number of guide pins 26, for example, four in each case. Each guide pin 26 can be inserted into a positioning hole, thus positioning the carrier 2 on the placement platform 11.

[0087] As mentioned above, the carrier 2 enters the housing through the opening and is positioned using the guide pin 26 and the aforementioned positioning hole. This process can be performed manually. Similarly, after the soft frame 6 is installed on the reflector, the carrier 2 is removed from the opening of the housing. In this process, especially during the installation of the carrier 2, as described above, the floating block 23 first contacts the placement platform 11. Thus, when the guide pin 26 is partially inserted into the mounting hole, the floating block 23, by its own floating action, ensures that the carrier 2, especially when manually installed, is cushioned and installed smoothly.

[0088] Furthermore, although not shown in the figure, the center of the workbench 10 is hollowed out. The placement platform 11 is supported by the workbench 10 and covers this hollowed-out portion. Below the workbench 10, corresponding to the position of the hollowed-out portion, the aforementioned positioning mechanism 12 is provided. The positioning mechanism 12 is used to position the reflector placed on the placement platform 11, which will be described in detail below.

[0089] Specifically, see Figure 9 , Figure 9 A schematic diagram of the front view of the positioning mechanism 12 is shown. The positioning mechanism 12 may include four plates, which, from bottom to top, are a base plate (not labeled), a lifting plate 128, a support plate 123, and a mounting plate 127. The support plate 123 may be mounted on the upper surface of the base plate via columns, for example, four columns.

[0090] See further Figure 9 and combined Figure 10 and Figure 11 The lifting plate 128 is located below the support plate 123 and can be connected to the movable ends of two first slide cylinders 129, which can be mounted on the aforementioned base plate. The upper end face of the lifting plate 128 can be provided with guide posts, such as four guide posts, which can pass through linear bearings 126 corresponding to those mounted on the support plate 123 and connect to the mounting plate 127 located above the support plate 123.

[0091] Thus, when the two first slide cylinders 129 drive the lifting plate 128 to move up and down, the mounting plate 127 moves up and down synchronously via four guide columns. During this process, the support plate 123 and the base plate are stationary relative to the ground; therefore, the up and down movement of the mounting plate 127 is actually a vertical movement relative to the support plate 123. Furthermore, a hydraulic buffer 124, such as four hydraulic buffers 124, can be provided between the mounting plate 127 and the support plate 123 to ensure that even when using cylinders for lifting, the mounting plate 127 can move up and down smoothly relative to the support plate 123.

[0092] See still Figure 9 The second slide cylinder 130 is mounted on the support plate 123, with its piston rod positioned above the cylinder body. A beveled block 122 is connected to the end of the piston rod. A hole is opened in the center of the mounting plate 127, allowing the beveled block 122 and the piston rod to pass through the hole and be positioned above the mounting plate 127. Further details are provided below. Figure 10 and Figure 11 As an example, the beveled block 122 can be formed as a frustum structure, where every two opposite sides can be identical. "Identical" here refers both to similarity in shape and similarity in the angle of inclination relative to the horizontal plane. As an example, in this embodiment, all four sides of the beveled block 122 can be identical, which further facilitates accurate positioning of the reflector; the specific positioning process will be described later.

[0093] Based on this, two sets of four connectors 125 are also provided above the mounting plate 127. Combined with... Figure 10 and Figure 11 And see especially Figure 10 , among which, along Figure 10 Two connectors 125 arranged horizontally in the middle are defined as the first set of connectors, along... Figure 10 The two vertically arranged connectors 125 are designated as the second set of connectors. Regarding the first set of connectors, the connectors 125 can be formed in a "T" shape, comprising two perpendicular beams. Specifically, one end face of one beam has the same inclination angle as the first side face of the four sides of the aforementioned beveled block 122, and the other end of this beam is perpendicular to and connected to the other beam. Further, both ends of the other beam are respectively provided with [features along...]. Figure 10 The horizontal extension has two limiting posts 121 on each of the two extensions.

[0094] See further Figure 10The limiting post 121 includes an upper large-diameter portion and a lower, relatively longer small-diameter portion, wherein a spring is fitted onto the small-diameter portion. Although not shown in the figures, alternatively, the lower end of the small-diameter portion may also have another large-diameter portion, which may be located below the extension. Thus, when the spring is provided, the spring is forced between the extension and the upper large-diameter portion, ensuring that the limiting post 121 will protrude relative to the upper end face of the extension when not subjected to sufficient vertical force.

[0095] Furthermore, a slider can be provided below the aforementioned connector 125, and a corresponding slide rail can be provided above the mounting plate 127. The slider cooperates with the slide rail, so that when the oblique cutting block 122 is driven upward by the second slide cylinder 130, the connector 125 can move outward relative to the mounting plate 127. For the purpose of resetting the connector 125, a spring can be provided between the inner end of the slider and the slide rail, so that when the oblique cutting block 122 descends, the connector 125 can move inward to reset.

[0096] Similarly, another connector 125 in the first set of connectors is the same as the connector 125 mentioned above, and it cooperates with the second side of the oblique block 122 opposite to the first side. The connector 125 is also provided with two limiting posts 121 in the same manner.

[0097] Similarly, the structure of connector 125 in the second set of connectors can be the same as that of connector 125 described above. As an example, in the positioning mechanism 12... Figure 10 In the retracted and positioned state, the second set of connectors can be understood as being located between the two connectors 125 in the first set of connectors. Therefore, the second set of connectors has a longer extension relative to the first set of connectors to accommodate the clamping of the rectangular reflector, which will be explained in detail in the following description.

[0098] Based on the above description, see also Figure 8 In this embodiment, the placement platform 11 has multiple through slots corresponding to the positions of the aforementioned limiting posts 121, allowing the limiting posts 121 to pass through and move along the through slots. In this embodiment, four through slots corresponding to the limiting posts 121 located on the first set of connectors 125 are arranged along... Figure 8 Extending horizontally, as four through slots corresponding to the limiting posts 121 provided on the second set of connectors 125, along... Figure 8 The oblique block 122 extends vertically. Thus, when the first and second sets of connectors open and close, the limiting posts 121 will not be obstructed in the through slot as the connector 125 moves. If a reflector is placed on the platform 11, when the first and second sets of connectors close, the limiting posts 121 abut against the edge of the reflector, thereby positioning the reflector.

[0099] The two opposite sides of the beveled block 122 have the same tilt angle, and the ends of the beams of the two connectors 125 that mate with the two opposite sides also have the same tilt angle. This makes the two connectors 125 included in a set of connectors move away from and closer to each other synchronously. This further enables the limiting posts 121 respectively set on them to synchronously position and release the two opposite sides of the reflector, especially avoiding the reflector from moving around, and effectively ensuring the positioning effect.

[0100] based on Figure 8 The pressure-holding mechanism 4 will be further described below. The pressure-holding mechanism 4 may include four pressure-holding members, each corresponding to one of the four sides of the rectangular reflector. Each pressure-holding member can be driven by a cylinder disposed on the worktable 10 to approach or move away from the edge or side of the reflector. Therefore, after the soft frame 6 is installed on the reflector, a portion of the soft frame 6 covers the side of the reflector, and the contact of the pressure-holding members further ensures that the soft frame 6 is reliably installed.

[0101] See further Figure 8 Based on the features described above, the structure and working principle of the installation mechanism 3 will be further described below. In the embodiment, the installation mechanism 3 includes an installation platform mounted on the workbench 10 via a column, and a pressure plate module is provided below the installation platform. The pressure plate module includes a pressure plate that floats via a floating shaft (not labeled, but its principle is the same as the floating shaft mentioned above, and the same applies to the floating shaft mentioned below) and floating pressure blocks located on both sides of the pressure plate that float via floating shafts.

[0102] Furthermore, the mounting platform is equipped with linear bearings, such as four linear bearings. The pressure plate module and the uppermost limiting plate are connected via guide posts passing through the four linear bearings. A cylinder is further provided on the mounting platform, connected to the lower pressure plate module. Driven by the piston of the cylinder, the pressure plate module and the limiting plate can rise and fall synchronously. In this embodiment, the mounting platform is also equipped with hydraulic buffers, such as two hydraulic buffers. When the limiting plate descends to a certain height, it will abut against the hydraulic buffers, thus allowing the pressure plate module to descend smoothly even under the drive of the cylinder. In this embodiment, when the limiting plate abuts against the hydraulic buffers, the pressure plate module has not yet contacted the carrier 2, which ensures that the pressure is always applied stably when the pressure plate module begins to apply pressure to the carrier 2.

[0103] Based on the above description of technical features, the working process of the pressing equipment will be further described below.

[0104] See especially Figure 2The oblique cutting block 122 of the positioning mechanism 12 rises, and the opposing limiting posts 121 move away from each other under the action of the connecting parts 125. At this time, the reflector is placed on the placement platform 11. Then the oblique cutting block 122 descends, and the limiting posts 121 reset. A total of eight limiting posts 121 abut against the side of the reflector, thereby effectively positioning the reflector and avoiding the problem of misalignment and installation failure when installing the soft frame 6 later. Further, the soft frame 6 is accommodated in the carrier 2, and the guide pin 26 of the carrier 2 is installed in the positioning hole of the placement platform 11. When the carrier 2 is installed, the carrier 2 does not contact the reflector, which avoids possible undesirable damage to the reflector. When viewed in the vertical direction, the outer edge of the soft frame 6 extends beyond the outer edge of the reflector. For example, the distance between the protrusion below the main body of the feeding carrier 21 and the reflector can be 0.5mm, which ensures that the soft frame 6 is close enough to the reflector for installation.

[0105] Furthermore, the mounting mechanism 3 presses down in the manner described above, causing the pressure plate module to press down on the adapter plate 25 of the carrier 2. The adapter plate 25 then causes the floating pressure plate 22 to descend. At the same time, the lifting plate 128 in the positioning mechanism 12 rises, thereby causing the mounting plate 127 and the various components mounted on it to rise together and abut against the bottom of the placement platform 11 via the hollow portion of the worktable 10, thus making the placement platform 11 relatively stable. As the floating pressure plate 22 descends, the soft frame 6 is pushed downward, so that part of the soft frame 6 covers the edge of the upper surface of the reflector, and another part covers the side of the reflector. The position of the soft frame 6 relative to the reflector is particularly conducive to this covering process.

[0106] In this way, the installation mechanism 3 and the positioning mechanism 12 work together to install the soft frame 6 onto the reflector. During this process, the floating pressure plate 22 also presses down the limiting post 121 of the positioning mechanism 12, so that the limiting post 121 will not affect the installation of the soft frame 6.

[0107] During the installation process, the installation mechanism 3 and positioning mechanism 12 are reset, the carrier 2 is removed, and then the pressure-holding component of the pressure-holding mechanism 4 moves towards the side of the reflector, pressing down the limiting post 121 again and pressing the portion of the soft frame 6 located on the side of the reflector. After holding the pressure for a certain period of time, the pressure-holding mechanism 4 is reset, the positioning mechanism 12 releases the positioning of the reflector, and the reflector with the soft frame 6 installed is removed from the placement platform 11.

[0108] See Figure 1Based on the above working process, safety light curtains 51 are installed on both sides of the opening in the housing. These are electrically connected to the control mechanism. Since manual operation of the equipment is required, if the safety light curtains 51 are blocked while the equipment is in operation, the control mechanism will pause the equipment to prevent production accidents. Furthermore, an emergency stop button 53 is also electrically connected to the control mechanism, and its function is to urgently stop the current equipment. In addition, Figure 1 A start button 52, which is also electrically connected to the control mechanism, is schematically shown in the diagram. It is used to start the current equipment and automatically implement the operation processes of the mounting mechanism 3, the positioning mechanism 12, and the pressure holding mechanism 4. In addition, a handle 54 is provided on the housing for moving the equipment.
