DETAILED DESCRIPTION

[0036] See also Figures 1-13 In an embodiment of the present invention, a bioluminescence instrument screen panel thermoforming device includes a hot pressing device 1, which is specifically a workbench for placing a workpiece to be processed, a telescopic arm that can be raised and lowered during hot pressing, and a hot pressing part fixed at its end. It can also be a hot pressing device commonly used for hot pressing work in the prior art. A mounting frame 101 is provided on the hot pressing device 1, and a placing plate 2 is slidably connected to the mounting frame 101 through a first slide groove 102. Preferably, the placing plate 2 is driven by a telescopic cylinder provided on the hot pressing device 1 to slide in the first slide groove 102, and the placing plate 2 can slide horizontally in the mounting frame 101. An adsorption mechanism is provided at the center of the placing plate 2, and multiple groups of positioning blocks 3 are slidably provided on the placing plate 2. The positioning blocks 3 are symmetrically arranged along the diagonal line of the placing plate 2, and a trigger mechanism is provided on the positioning block 3. The trigger mechanism and the adsorption mechanism are connected through a transmission mechanism. When the trigger mechanism is relatively far away from the adsorption mechanism, the adsorption mechanism is moved downward by the transmission mechanism.

[0037] Furthermore, the bottom surface of the positioning block 3 is fixedly connected to a square tube 18, and sliders 21 are fixedly connected to both sides of the square tube 18. A guide groove 6 is provided along the diagonal of the placement plate 2, so that the positioning block 3 moves along the diagonal of the placement plate 2 under the action of the guide groove 6, thereby adaptively moving the workpiece to be processed to the center of the placement plate 2, facilitating subsequent hot pressing processing. The square tube 18 is slidably connected to the guide groove 6 through the slider 21, and the square tube 18 and the guide groove 6 are elastically connected by a spring. The bottom end of the square tube 18 away from the positioning block 3 is fixedly connected to a fixed block 8, and the fixed block 8 and the transmission mechanism are connected by a pull rope 13. The positioning block 3 is slidably connected to the placement plate 2 through the cooperation among the square tube 18, the slider 21 and the guide groove 6.

[0038] During specific use, when the workpiece is not subjected to hot pressing, under the action of the spring, four groups of positioning blocks 3 are preferably provided, and in the initial state, they correspond to the corners of the placement plate 2 respectively, and the trigger mechanism extends out of the side wall of the positioning block 3, and the placement plate 2 is at the end away from the hot pressing part in the installation frame 101; when the substrate, circuit board, etc. that need to be hot pressed or other components that need to be hot pressed are placed on the placement plate 2 in turn, the substrate and circuit board are taken as an example below, and then the placement plate 2 is pushed to move relative to the hot pressing part in the installation frame 101. In this process, the multiple groups of fixed blocks 8 are synchronously moved relatively close to each other through the transmission mechanism, and the multiple groups of positioning blocks 3 are moved relatively close to each other along the guide groove 6 through the square tube 18, and the process is completed. The trigger mechanism moves synchronously and approaches, thereby contacting the workpiece to be processed placed on the placement plate 2, and moving the workpiece to be processed to the center of the placement plate 2, so as to facilitate the hot pressing work on it by the hot pressing part, and avoid the occurrence of defective products due to the offset between the initially placed substrate and the circuit board to be hot pressed on the substrate. For example, when the substrate is moved to the center, as the positioning block 3 continues to move, the trigger mechanism moves relatively and shrinks in the positioning block 3, and the trigger mechanism drives the transmission mechanism to move downward, so that the adsorption mechanism moves downward to adsorb and fix the substrate, and then the positioning block 3 will move and reset in the guide groove 6 under the action of the square tube 18 and the spring, so that the positioning block 3 does not affect the hot pressing work.

[0039] See also Figure 4 、 Figure 9 The adsorption mechanism includes a driving disc 16; the central array of the placing plate 2 is provided with an adsorption hole 5, and the inner wall of the placing plate 2 is provided with a cavity 15 below the adsorption hole 5, and the cavity 15 is connected to the adsorption hole 5, and the driving disc 16 is slidably embedded in the cavity 15. When the driving disc 16 slides downward in the cavity 15, the workpiece placed on the placing plate 2 can be adsorbed and fixed through the adsorption hole 5, and the driving disc 16 and the cavity 15 are sealed and slidably adapted, and the driving disc 16 and the cavity 15 away from the adsorption hole 5 are elastically connected by a spring, and a movable groove 22 is provided in the center of the driving disc 16. The specific structure of the driving disc 16 is composed of three layers of circular rings, and the bottom end of the placing plate 2 away from the adsorption hole 5 is provided with a through hole that is slidably adapted to the bottom section of the driving disc 16, and the through hole is connected to the cavity 15, and the transmission mechanism is slidably connected to the movable groove 22. When the transmission mechanism is relatively away from the driving disc 16, the driving disc 16 is driven to move downward.

[0040] During specific use, when the workpiece to be hot-pressed is placed on the placement plate 2 and is in the initial state without being adsorbed and fixed, the driving disc 16 approaches the adsorption hole 5 under the action of the spring; when the trigger component moves relative to the positioning block 3 and shrinks in the positioning block 3, the driving disc 16 is relatively away from the adsorption hole 5 through the transmission mechanism, thereby increasing the space between the driving disc 16 and the adsorption hole 5, generating negative pressure, and the substrate placed on the placement plate 2 is adsorbed and fixed through the adsorption hole 5, thereby achieving the problem of no offset when the substrate or circuit board is hot-pressed.

[0041] See also Figure 4-Figure 7 、 Figure 13 The trigger mechanism includes a trigger block 4; a fixed plate 20 is fixedly connected to one side of the trigger block 4, and a square piston 19 is fixedly connected to the end of the fixed plate 20 away from the trigger block 4. The positioning block 3 is hollow, and the trigger block 4, the fixed plate 20, and the square piston 19 are all slidably embedded in the positioning block 3, and are sealed and slidingly connected to the positioning block 3. The side of the square piston 19 close to the trigger block 4 is elastically connected to the inner wall of the positioning block 3 through a spring. A first through-groove communicating with the positioning block 3 is opened in the center of the square tube 18, and a second through-groove communicating with the through hole is opened in the center of the fixed block 8. A push rod 14 is slidably connected in the second through-groove, and a connecting assembly is provided at the bottom end of the push rod 14 away from the fixed block 8. When the trigger block 4 moves relative to the positioning block 3, the push rod 14 is driven to move downward in the second through-groove through the first through-groove, and then the transmission mechanism moves downward through the connecting assembly. The trigger block 4 is provided with an inclined surface, and the movement trajectory of the trigger block 4 on the positioning block 3 is relatively away from or close to the movement direction of the first slide groove 102, and the inclined surfaces on the two groups of trigger blocks 4 close to the first slide groove 102 are arranged opposite to each other. In this way, when the substrate contacts, the corner of the substrate contacts and slides with the inclined surface of the trigger block 4, thereby avoiding damage to the corner of the substrate.

[0042] When in use, when hot pressing is not performed, the positioning block 3 is at the corner of the placement plate 2, the trigger block 4 extends out of the positioning block 3, and the side of the square piston 19 away from the trigger block 4 fits the inner wall of the positioning block 3; when the trigger block 4 moves relative to the positioning block 3 and shrinks in the positioning block 3, the trigger block 4 causes the square piston 19 to slide in the positioning block 3 relative to the trigger block 4 through the fixing plate 20, thereby compressing the gas in the positioning block 3, and the push rod 14 moves downward through the cooperation of the first through groove and the second through groove. The downward movement of the push rod 14 causes the connecting assembly to move downward, and then causes the transmission mechanism to move downward. The downward movement of the transmission mechanism first causes the adsorption mechanism to complete the adsorption and fixation of the substrate moved to the center position, and then causes the positioning block 3 to move and reset.

[0043] See also Figure 3-Figure 5 、 Figure 8 、 Figure 13When the cam 10 is in the forward direction, the cam 10 is in the forward direction, and the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, and the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, and the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, and the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, so that the cam 10 is in the forward direction, so that the cam 10 is in the forward direction,

[0044] See also Figures 1-4 、 Figure 9 The transmission mechanism includes a rotating shaft 17; the bottom end of the rotating shaft 17 is fixedly connected to a gear 11, and a rack 7 is meshed with the gear 11. The end of the gear 11 away from the rotating shaft 17 is rotatably connected to the connecting assembly. Specifically, the center of the end of the gear 11 away from the rotating shaft 17 is rotatably connected to the top center of the telescopic plate 10 via a rotating shaft. The end of the rotating shaft 17 away from the gear 11 is slidably connected to the inner wall of the movable groove 22, and the rotating shaft 17 can rotate within the movable groove 22. The end of the pull rope 13 away from the trigger mechanism is fixedly connected to the rotating shaft 17, and the two ends of the rack 7 are fixedly connected to the mounting frame 101. The end of the rotating shaft 17 away from the gear 11 is a disc structure, and in the initial state, there is a certain space between the disc at the end of the rotating shaft 17 and the bottom end of the inner wall of the driving disc 16. In this way, when the rotating shaft 17 moves downward, it first moves downward in the movable groove 22, thereby enhancing the adsorption effect after the driving disc 16 moves downward.

[0045] When in use, when hot pressing is not in progress, the positioning block 3 is at the corner of the placement plate 2, the trigger assembly extends out of the positioning block 3, and the rotating shaft 17 cooperates with the trigger mechanism and the connecting assembly. There is a certain space between the top of the rotating shaft 17 and the bottom end of the inner wall of the movable groove 22, and the gear 11 is meshed with the rack 7; when the placement plate 2 slides relative to the hot pressing part in the installation frame 101, since the gear 11 is meshed with the rack 7, and the rack 7 is fixed, the placement plate 2 slides to make the gear 11 rotate. The gear 11 rotates to rotate the shaft 17, and the rotation of the shaft 17 causes the pull rope 13 to be wound around the shaft 17. The pull rope 13 is wound so that the fixed block 8 moves relative to the gear 11 under the guidance of the square tube 18 and the guide groove 6. The fixed block 8 moves so that the push rod 14, the square tube 18, and the positioning block 3 move closer to each other, and the push rod 14 slides relatively on the connecting rod 9. The telescopic plate 10 gradually shrinks, and the positioning block 3 moves to align the substrate and the material thereon, and the substrate is placed At the center of plate 2, when the trigger block 4 moves relatively and shrinks in the positioning block 3, the push rod 14 moves downward through the cooperation of the trigger block 4, the fixed plate 20, the square piston 19, the first through groove and the second through groove. The push rod 14 moves downward, causing the connecting rod 9 to move downward, and the connecting rod 9 moves downward, causing the telescopic plate 10 to move downward. The telescopic plate 10 moves downward, driving the gear 11 to move downward and separate from the rack 7. The gear 11 moves downward, driving the rotating shaft 17 to move downward, and the rotating shaft 17 moves downward to fit the bottom of the inner wall of the movable groove 22 and drive the driving disc 16 to move. The driving disc 16 moves downward in the cavity 15 and completes the adsorption and fixation of the substrate through the adsorption hole 5, and the gear 11 is separated from the rack 7. Since the square tube 18 moves closer to the gear 11, the spring is compressed. Therefore, when the gear 11 is separated from the rack 7, the spring resets and pushes the square tube 18 to move and reset. The square tube 18 moves and resets, causing the fixed block 8 to move and reset, and the fixed block 8 moves and resets, thereby pulling out the pull rope 13 on the rotating shaft 17.

[0046] See also Figure 3 、 Figures 9-12The end of the rotating shaft 17 away from the gear 11 is slidably matched with two sets of second limit blocks 25. The second limit blocks 25 are slidably embedded in the side wall of the driving disc 16, and the second limit blocks 25 are symmetrically arranged along the center of the driving disc 16 and seal and slide with the inner wall of the driving disc 16. The second limit blocks 25 are elastically connected to the driving disc 16 through a spring. A limit groove 23 is provided on the end side wall of the driving disc 16 away from the adsorption hole 5. The limit groove 23 is symmetrically arranged along the center of the driving disc 16, and two sets of opposite first limit blocks 2 are arranged in the limit groove 23. 4. A spring is disposed between the two sets of first limit blocks 24. The end of the first limit block 24 facing away from the spring is inclined. The inclined surface of the first limit block 24 near the rotating shaft 17 is oriented toward the rotating shaft 17, while the inclined surface of the other first limit block 24 is oriented in the opposite direction. A reset rod 12 is fixedly connected to the inner wall of the mounting frame 101 and cooperates with the first limit block 24. The end of the reset rod 12 near the rotating shaft 17 is inclined toward the rotating shaft 17, and the inclined surface of the reset rod 12 faces the rotating shaft 17. This prevents the reset rod 12 from getting stuck when it cooperates with the first limit block 24. The second limit block 25 and the limiting groove 23 are interlaced. The second limit block 25 moves relative to the rotating shaft 17 to limit the relative position of the rotating shaft 17 and the drive disc 16. The first limit block 24 moves away from the rotating shaft 17 to limit the relative position of the drive disc 16 and the placement plate 2.

[0047] In specific use, when the workpiece is not being hot-pressed, the placement plate 2 is located in the mounting frame 101 at the end away from the hot-pressing portion, the second limit block 25 is retracted into the side wall of the driving disc 16, the first limit block 24 close to the rotating shaft 17 extends out of the limit groove 23, and the outer ring side wall of the end disc of the rotating shaft 17 is flush with the second limit block 25;When the gear 11 is moved downward by the trigger mechanism and the connecting assembly, the rotating shaft 17 moves downward so that the disc at its end fits against the bottom of the inner wall of the movable groove 22, thereby making the height of the rotating shaft 17 lower than the second limit block 25. At the same time, the rotating shaft 17 also slides with a first limit block 24, so that a first limit block 24 moves and shrinks in the limit groove 23. A first limit block 24 moves through a spring so that the other first limit block 24 is relatively away from the rotating shaft 17 and extends out of the limit groove 23. At this time, the rotating shaft 17 continues to move downward, driving the driving disc 16 to move downward in the cavity 15. Since a substrate is placed on the placing plate 2 and the substrate fits against the adsorption hole 5, the adsorption hole 5 is not It is connected to the outside, so that when the driving disc 16 slides downward in the cavity 15, negative pressure is generated to adsorb and fix the substrate. At the same time, due to the effect of the negative pressure, the second limit block 25 extends out of the side wall of the driving disc 16 to limit the relative position of the rotating shaft 17 and the driving disc 16. The spring corresponding to the second limit block 25 is stretched. Since the other first limit block 24 extends out of the outer wall of the driving disc 16, when the driving disc 16 moves downward, the other first limit block 24 slides with the inner wall of the placement plate 2 through the inclined surface, so that the other first limit block 24 is squeezed and contracted in the limit groove 23, and the spring between the two first limit blocks 24 is compressed. When the first limit block 24 provided at the bottom end of the driving disc 16 extends out of the bottom of the placement plate 2, the other first limit block 24 extends out of the limit groove 23 under the action of the spring, that is, the outer wall of the protruding driving disc 16 slides and fits with the bottom of the placement plate 2 to complete the limitation of the relative position of the driving disc 16 and the placement plate 2, so that the substrate and the material thereon are always adsorbed and fixed during hot pressing. Since the relative positions between the rotating shaft 17 and the driving disc 16 and between the driving disc 16 and the placement plate 2 are respectively limited, the position of the gear 11 is limited, so that the vertical direction of the connecting component is limited and cannot move, thereby making the trigger mechanism unable to move and reset. After the hot pressing is completed, the placement plate 2 moves and resets within the mounting frame 101, causing the first limit block 24 to slide with the reset rod 12, squeezing the first limit block 24 into the limit groove 23. This resets the trigger mechanism, the connecting assembly, and the drive disc 16. The drive disc 16 resets and reengages the substrate. At this point, due to the normal pressure difference between the cavity 15 and the drive disc 16, the second limit block 25 moves and resets under the action of the spring, thereby releasing the relative position limit between the rotating shaft 17 and the drive disc 16. With the complete reset of the trigger assembly, the rotating shaft 17 continues to move upward and reset within the drive disc 16, and the gear 11 resets and engages with the rack 7.
