[0006] To achieve the above objectives, the present invention provides the following technical solution: an OCA bonding device, comprising a device body, and further comprising:

[0007] The transfer mechanism, symmetrically installed on the device body, is used to transfer OCA colloid.

[0008] A support mechanism, mounted on the device body, is used to support the substrate; and a rolling mechanism, mounted on the device body, is used to bond the OCA colloid to the substrate.

[0009] The supporting mechanism includes automatic suction cups and second rotating shafts. Two second rotating shafts are symmetrically rotatably connected to the device body. Two automatic suction cups are correspondingly sleeved on and fixedly connected to the second rotating shafts. The mechanism also includes:

[0010] A limiting component, mounted on an automatic suction cup, is used to limit the substrate on the automatic suction cup; and a driving component, mounted on the device body, is used to drive the automatic suction cup to rotate.

[0011] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0012] Further technical solution: The limiting component includes a pressure plate and a first linear motion component. The two pressure plates are symmetrically arranged on the automatic suction cup. The pressure plate is fixedly connected to the end of the first linear motion component, and the first linear motion component is embedded and fixedly connected to the automatic suction cup.

[0013] Further technical solution: The drive assembly includes a second motor and a third rotating shaft. The second motor is fixedly connected to the device body. The second motor is connected to the third rotating shaft, which is rotatably connected to the device body, through a first coupling. The third rotating shaft is connected to the second rotating shaft through a transmission pair.

[0014] Further technical solution: The roller pressing mechanism includes a support plate and a mounting plate. The support plate is slidably fitted with the device body and threadedly connected to a rod rotatably connected to the device body. The mounting plate is detachably connected to the inner wall of the top of the support plate via a first magnetic attraction assembly. It also includes:

[0015] The pressing assembly, mounted on the device body, is used for roller pressing;

[0016] A pushing component, mounted on the device body, is used to push the mounting plate to move linearly in the vertical direction along the support plate; and a power component, mounted on the device body, is used to provide kinetic energy to the pressing component.

[0017] Further technical solution: The pressing assembly includes a fourth rotating shaft, a support frame, a first half-roller, a second half-roller, and a third linear motion component. The two fourth rotating shafts are symmetrically fixedly connected to the mounting plate. The support frame is sleeved on the fourth rotating shaft and rotatably connected to the fourth rotating shaft. The first half-roller and the second half-roller are symmetrically arranged on both sides of the support frame. The first half-roller and the second half-roller are both fixedly connected to the third linear motion component fixedly connected to the support frame.

[0018] Further technical solution: The pushing component includes a second linear motion component, a pressure sensor, and a first connecting plate. The second linear motion component is embedded and fixedly connected to the support plate. The pressure sensor is fixedly connected to the end of the second linear motion component. The first connecting plate is detachably connected to the mounting plate via a second magnetic suction component.

[0019] Further technical solution: The power assembly includes an elastic element and a second connecting plate. One end of the elastic element is fixedly connected to the support plate, and the other end of the elastic element is fixedly connected to the second connecting plate. The second connecting plate is detachably connected to the mounting plate through a third magnetic suction assembly.

[0020] A further technical solution: The OCA adhesive used in the OCA bonding device includes adhesive edges and adhesive body, and several adhesive edges are loosely connected to the adhesive body.

[0021] A further technical solution: Several adhesive edges are divided into several groups, and each group contains an adhesive edge with a different length from the other adhesive edges. This adhesive edge is used for peel strength testing. The thickness of the adhesive edge is greater than the thickness of the adhesive body. The adhesive edge and the adhesive body can be in the form of a roll.

[0022] The bonding method of the above-mentioned OCA bonding device includes the following steps:

[0023] S1. The first motor drives the first rotating shaft to rotate horizontally through the second coupling, and the first rotating shaft drives the drum to rotate synchronously, thereby realizing the transfer of OCA colloid wound into a cylinder.

[0024] S2. The second linear motion component drives the mounting plate to make linear motion in the vertical direction through the first connecting plate, causing the first half roller and the second half roller to press the OCA colloid onto the substrate with a certain pressure. At this time, the rotating rod pushes the support plate to make linear motion in the horizontal direction, that is, pushes the first half roller and the second half roller to roll along the substrate to press the OCA colloid onto the substrate.

[0025] S3. After the OCA bonding is completed, the relevant technicians can selectively activate the second linear motion component to push the pressure sensor and drive the mounting plate to perform linear motion in the vertical direction until the mounting plate is fixed on the inner wall of the top of the support plate by the first magnetic suction component. At this time, the second magnetic suction component is released from the limit of the mounting plate, and the second linear motion component is reset. At this time, the first magnetic suction component is released from the limit of the mounting plate, and the elastic component pulls the mounting plate to perform linear motion in the vertical direction, that is, the first half roller or the second half roller impacts the substrate mounted on the automatic suction cup with a certain kinetic energy, and the impact performance test is performed on the substrate that has completed OCA bonding.

[0026] S4. Relevant technicians can drive the third rotating shaft to rotate horizontally via the second motor. The third rotating shaft drives the second rotating shaft to rotate via a transmission pair. The second rotating shaft pushes the automatic suction cup to rotate 90 degrees, which in turn drives the substrate with the OCA colloid to rotate 90 degrees, thus bringing it into a vertical position. At this time, the third linear motion component pushes the first half-roller and the second half-roller to move linearly in opposite directions. The OCA colloid is now located between the first half-roller and the second half-roller. The third linear motion component is activated again to make the first half-roller and the second half-roller clamp the OCA colloid. At this time, the second linear motion component drives the pressure sensor to drive the mounting plate to move linearly vertically. The mounting plate drives the first half-roller and the second half-roller to move linearly synchronously, which pulls the OCA colloid attached to the substrate to gradually detach from the substrate. The pressure sensor is used to monitor the peel force in real time and to test the peel force strength of the OCA colloid. Beneficial effects

[0027] This invention provides an OCA bonding device, which has the following advantages compared with the prior art:

[0028] The second linear motion component drives the mounting plate to move vertically through the first connecting plate, causing the first half-roller and the second half-roller to press the OCA colloid onto the substrate with a certain pressure. At this time, the rotating rod pushes the support plate to move horizontally, that is, pushes the first half-roller and the second half-roller to roll at a constant speed along the substrate, so as to achieve the technical effect of pressing the OCA colloid onto the substrate and reducing the occurrence of air bubbles due to uneven pressure.

[0029] After OCA bonding is completed, relevant technicians can selectively activate the second linear motion component to push the pressure sensor and drive the mounting plate to move linearly in the vertical direction until the mounting plate is fixed to the inner wall of the top of the support plate by the first magnetic suction component. At this time, the second magnetic suction component is released from the limit of the mounting plate, and the second linear motion component is reset. Then, the first magnetic suction component is released from the limit of the mounting plate, and the elastic component pulls the mounting plate to move linearly in the vertical direction. This causes the first half-roller or the second half-roller to impact the substrate mounted on the automatic suction cup with a certain kinetic energy, thereby achieving the technical effect of impact performance testing on the substrate that has completed OCA bonding.

[0030] The technicians can also use a second motor to drive a third rotating shaft to rotate horizontally. The third rotating shaft drives a second rotating shaft to rotate via a transmission pair. The second rotating shaft pushes an automatic suction cup to rotate 90 degrees, which in turn rotates the substrate with the OCA colloid to a vertical position. At this time, the third linear motion component pushes the first and second half-rollers to move linearly in opposite directions. The OCA colloid is now located between the first and second half-rollers. The third linear motion component is then activated again to clamp the OCA colloid between the first and second half-rollers. The second linear motion component then uses a pressure sensor to drive a mounting plate to move linearly vertically. The mounting plate drives the first and second half-rollers to move linearly synchronously, pulling the OCA colloid adhered to the substrate to gradually detach from the substrate. The pressure sensor is used to monitor the peel force in real time, thus achieving the technical effect of detecting the peel force strength of the OCA colloid. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0042] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0043] Please see Figures 1-3 According to one embodiment of the present invention, an OCA bonding device includes a device body 1, and further includes:

[0044] The transfer mechanism 2 is symmetrically installed on the device body 1 and is used to transfer the OCA colloid 5.

[0045] The support mechanism 3 is mounted on the device body 1 and is used to support the substrate; and the rolling mechanism 4 is mounted on the device body 1 and is used to attach the OCA colloid 5 to the substrate.

[0046] The supporting mechanism 3 includes an automatic suction cup 301 and a second rotating shaft 302. The two second rotating shafts 302 are symmetrically rotatably connected to the device body 1. The two automatic suction cups 301 are correspondingly sleeved on the second rotating shafts 302 and correspondingly fixedly connected to the second rotating shafts 302. It also includes:

[0047] A limiting component 306 is mounted on an automatic suction cup 301 to limit the substrate on the automatic suction cup 301; and a driving component is mounted on the device body 1 to drive the automatic suction cup 301 to rotate.

[0048] Preferably, the limiting component 306 includes a pressure plate 3061 and a first linear motion member 3062. Two pressure plates 3061 are symmetrically arranged on the automatic suction cup 301. The pressure plates 3061 are fixedly connected to the ends of the first linear motion member 3062, which is embedded and fixedly connected to the automatic suction cup 301. The purpose of this arrangement is to use the first linear motion member 3062 to push the pressure plates 3061 in linear motion, and the two pressure plates 3061 achieve the technical effect of limiting the substrate by performing linear movements in opposite directions.

[0049] Preferably, the driving assembly includes a second motor 303 and a third rotating shaft 304. The second motor 303 is fixedly connected to the device body 1. The second motor 303 is connected to the third rotating shaft 304, which is rotatably connected to the device body 1, via a first coupling. The third rotating shaft 304 is connected to the second rotating shaft 302 via a transmission pair 305. The second motor 303 drives the third rotating shaft 304 to rotate horizontally via the first coupling. The third rotating shaft 304 drives the second rotating shaft 302 to rotate via 205. The second rotating shaft 302 drives the automatic suction cup 301 to rotate, thereby rotating the automatic suction cup 301 and causing it to be in a vertical position. That is, the substrate limited to the automatic suction cup 301 by the limiting component 306 is in a vertical position.

[0050] In this embodiment of the invention, a person skilled in the art can place the substrate on the automatic suction cup 301 and initially limit it under the negative pressure adsorption of the automatic suction cup 301. At this time, the driving limiting component 306 limits the substrate, causing the substrate to be limited on the automatic suction cup 301. At this time, the transfer component transfers the OCA colloid 5 to directly above the substrate. At this time, the roller pressing mechanism 4 is activated to roll the OCA colloid 5 onto the substrate, thereby completing the OCA bonding of the substrate and reducing the technical effect of bubbles caused by uneven pressure application.

[0051] Please see Figures 1-6 As an embodiment of the present invention, the roller pressing mechanism 4 includes a support plate 401 and a mounting plate 402. The support plate 401 is slidably engaged with the device body 1, and the support plate 401 is threadedly connected to a rod 406 rotatably connected to the device body 1. The mounting plate 402 is detachably connected to the inner top wall of the support plate 401 via a first magnetic attraction assembly. The mechanism also includes:

[0052] A pressing assembly 405 is installed on the device body 1 for roller pressing. The pressing assembly 405 includes a fourth rotating shaft 4051, a support frame 4052, a first half-roller 4053, a second half-roller 4054, and a third linear motion component 4055. The two fourth rotating shafts 4051 are symmetrically fixedly connected to the mounting plate 402. The support frame 4052 is sleeved on the fourth rotating shafts 4051 and rotatably connected to the fourth rotating shafts 4051. The first half-roller 4053 and the second half-roller 4054 are symmetrically arranged on both sides of the support frame 4052. The first half-roller 4053 and the second half-roller 4054 are both fixedly connected to the third linear motion component 4055 fixedly connected to the support frame 4052.

[0053] A pushing component 403, mounted on the device body 1, is used to push the mounting plate 402 to move linearly in the vertical direction along the support plate 401; and a power component 404, mounted on the device body 1, is used to provide kinetic energy to the pressing component 405.

[0054] Specifically, the pushing assembly 403 includes a second linear motion component 4031, a pressure sensor 4032, and a first connecting plate 4033. The second linear motion component 4031 is embedded and fixedly connected to the support plate 401. The pressure sensor 4032 is fixedly connected to the end of the second linear motion component 4031. The first connecting plate 4033 is detachably connected to the mounting plate 402 via a second magnetic attachment assembly. The second linear motion component 4031 pushes the pressure sensor 4032, causing the first connecting plate 4033 to move linearly in the vertical direction. The first connecting plate 4033 simultaneously pushes the mounting plate 402 to move linearly in the vertical direction. The purpose of this arrangement is to change the position of the pressing assembly 405 in the vertical direction.

[0055] Specifically, the power assembly 404 includes an elastic element 4041 and a second connecting plate 4042. One end of the elastic element 4041 is fixedly connected to the support plate 401, and the other end of the elastic element 4041 is fixedly connected to the second connecting plate 4042. The second connecting plate 4042 is detachably connected to the mounting plate 402 via a third magnetic traction assembly. The purpose of this arrangement is to use the elasticity of the elastic element 4041 to pull the mounting plate 402, thereby driving the pressing assembly 405 to perform linear vertical movement, so as to achieve impact testing on the substrate after the OCA colloid 5 has been bonded, thus achieving the technical effect of testing its impact performance.

[0056] Specifically, the third linear motion component 4055 is an electric telescopic rod. Those skilled in the art should know that the purpose of this arrangement is to drive the first half-roller 4053 or the second half-roller 4054 to perform linear motion. Therefore, in some embodiments, the third linear motion component 4055 can also be set as any one of a cylinder, a hydraulic cylinder, and a linear motor.

[0057] Specifically, the second linear motion member 4031 is an electric telescopic rod. Those skilled in the art should know that the purpose of this arrangement is to drive the mounting plate 402 to perform linear motion. Therefore, in some embodiments, the second linear motion member 4031 can also be set as any one of a cylinder, a hydraulic cylinder, and a linear motor.

[0058] Specifically, the elastic element 4041 is a spring. Those skilled in the art should know that the purpose of this arrangement is to provide elastic power to the mounting plate 402. Therefore, in some embodiments, the elastic element 4041 can also be a compression spring, an elastic steel plate, or other components that can provide elastic force.

[0059] In this embodiment of the invention, firstly, the second linear motion component 4031 drives the mounting plate 402 to perform linear motion in the vertical direction via the first connecting plate 4033, causing the first half-roller 4053 and the second half-roller 4054 to press the OCA colloid 5 against the substrate with a certain pressure. At this time, the rotating rod 406 pushes the support plate 401 to perform linear motion in the horizontal direction, that is, pushes the first half-roller 4053 and the second half-roller 4054 to roll along the substrate, so as to achieve the technical effect of rolling the OCA colloid 5 onto the substrate. Secondly, after the OCA bonding is completed, the relevant technicians can selectively activate the second linear motion component. 4031 pushes the pressure sensor 4032 to drive the mounting plate 402 in a vertical linear motion until the mounting plate 402 is fixed to the inner top wall of the support plate 401 by the first magnetic suction assembly. At this time, the second magnetic suction assembly releases the restriction on the mounting plate 402 and causes the second linear motion component 4031 to reset. Then, the first magnetic suction assembly releases the restriction on the mounting plate 402, and the elastic component 4041 pulls the mounting plate 402 in a vertical linear motion. This causes the first half-roller 4053 or the second half-roller 4054 to impact the substrate mounted on the automatic suction cup 301 with a certain kinetic energy, thereby achieving the bonding of the substrate after OCA bonding. The technical effect of impact performance testing on the board is demonstrated. Finally, relevant technicians can also drive the third rotating shaft 304 to rotate horizontally via the second motor 303. The third rotating shaft 304 drives the second rotating shaft 302 to rotate via the transmission pair 305. The second rotating shaft 302 pushes the automatic suction cup 301 to rotate 90 degrees, that is, it drives the substrate with OCA colloid 5 to rotate 90 degrees, thus making it vertical. At this time, the third linear motion component 4055 correspondingly pushes the first half-roller 4053 and the second half-roller 4054 to perform linear motion in opposite directions. At this time, the OCA colloid 5 is located between the first half-roller 4053 and the second half-roller 4054. Between the two half-rollers 4054, the third linear motion component 4055 is activated again to cause the first half-roller 4053 and the second half-roller 4054 to clamp the OCA colloid 5. At this time, the second linear motion component 4031 pushes the pressure sensor 4032 to drive the mounting plate 402 to perform linear motion in the vertical direction. The mounting plate 402 drives the first half-roller 4053 and the second half-roller 4054 to perform synchronous linear motion, that is, to pull the OCA colloid 5 attached to the substrate to gradually detach from the substrate. The pressure sensor 4032 is used to monitor the peel force in real time, so as to achieve the technical effect of detecting the peel force strength of the OCA colloid 5.

[0060] Please see Figure 1 as well as Figure 7As an embodiment of the present invention, the transfer mechanism 2 includes a first motor 201, a first rotating shaft 202, a drum 203, and rubber rollers 204. The first motor 201 is detachably connected to the device body 1. The two first motors 201 symmetrically arranged on the device body 1 are connected to the first rotating shaft 202 rotatably connected to the device body 1 through a second coupling. The drum 203 is sleeved on the first rotating shaft 202 and fixedly connected to the first rotating shaft 202. The two rubber rollers 204 are symmetrically rotatably connected to the device body 1.

[0061] Specifically, the first motor 201 is detachably connected to the device body 1 via a bolt assembly. Those skilled in the art should know that the purpose of this arrangement is to confine the first motor 201 to the device body 1. Therefore, in some embodiments, the first motor 201 can also be detachably connected to the device body 1 by snap-fit ​​or fixedly connected to the device body 1 by welding.

[0062] In this embodiment of the invention, the first motor 201 drives the first rotating shaft 202 to rotate in the horizontal direction through the second coupling, and the first rotating shaft 202 drives the drum 203 to rotate synchronously, thereby achieving the technical effect of transferring the OCA colloid 5 wound into a cylinder.

[0063] Please see Figure 8 as well as Figure 9 The OCA adhesive 5 used in the above-mentioned OCA bonding device includes an adhesive edge 501 and an adhesive body 502. Several adhesive edges 501 are loosely connected to the adhesive body 502. The several adhesive edges 501 are divided into several groups, and each group contains an adhesive edge 501 with a different length from the other adhesive edges 501. The adhesive edge 501 is used for peel strength testing. The adhesive edge 501 and the adhesive body 502 can be in the form of a roll. The thickness of the adhesive edge 501 is greater than the thickness of the adhesive body 501.

[0064] Specifically, the aforementioned linear motion component is any one of an electric telescopic rod, a pneumatic cylinder, a hydraulic cylinder, and a linear motor.

[0065] The overall working principle of this invention:

[0066] First, the first motor 201 drives the first rotating shaft 202 to rotate horizontally through the second coupling. The first rotating shaft 202 drives the drum 203 to rotate synchronously, thereby realizing the transfer of the OCA colloid 5 wound into a cylinder.

[0067] Secondly, the second linear motion component 4031 drives the mounting plate 402 to perform linear motion in the vertical direction through the first connecting plate 4033, causing the first half roller 4053 and the second half roller 4054 to press the OCA colloid 5 against the substrate with a certain pressure. At this time, the rotating rod 406 pushes the support plate 401 to perform linear motion in the horizontal direction, that is, pushes the first half roller 4053 and the second half roller 4054 to roll along the substrate, so as to roll the OCA colloid 5 onto the substrate.

[0068] Secondly, after the OCA bonding is completed, the relevant technicians can selectively activate the second linear motion component 4031 to push the pressure sensor 4032 to drive the mounting plate 402 to perform linear motion in the vertical direction until the mounting plate 402 is fixed to the top inner wall of the support plate 401 by the first magnetic suction component. At this time, the second magnetic suction component is released from limiting the mounting plate 402, and the second linear motion component 4031 is reset. At this time, the first magnetic suction component is released from limiting the mounting plate 402, and the elastic component 4041 pulls the mounting plate 402 to perform linear motion in the vertical direction, that is, it causes the first half roller 4053 or the second half roller 4054 to impact the substrate mounted on the automatic suction cup 301 with a certain kinetic energy, and perform impact performance testing on the substrate that has completed OCA bonding.

[0069] Finally, the relevant technicians can drive the third rotating shaft 304 to rotate horizontally via the second motor 303. The third rotating shaft 304 drives the second rotating shaft 302 to rotate via the transmission pair 305. The second rotating shaft 302 pushes the automatic suction cup 301 to rotate 90 degrees, which in turn drives the substrate with the OCA colloid 5 to rotate 90 degrees, thus bringing it into a vertical position. At this time, the third linear motion component 4055 correspondingly pushes the first half-roller 4053 and the second half-roller 4054 to perform linear motion in opposite directions. At this time, the OCA colloid 5 is located between the first half-roller 4053 and the second half-roller. Between 4054, the third linear motion component 4055 is activated again to cause the first half roller 4053 and the second half roller 4054 to clamp the OCA colloid 5. At this time, the second linear motion component 4031 pushes the pressure sensor 4032 to drive the mounting plate 402 to perform linear motion in the vertical direction. The mounting plate 402 drives the first half roller 4053 and the second half roller 4054 to perform synchronous linear motion, that is, to pull the OCA colloid 5 attached to the substrate to gradually detach from the substrate. The pressure sensor 4032 is used to monitor the peeling force in real time and to detect the peeling force strength of the OCA colloid 5.

9. The bonding method of the OCA bonding device according to claim 8, characterized in that, Includes the following steps: S1. The first motor (201) drives the first rotating shaft (202) to rotate horizontally through the second coupling. The first rotating shaft (202) drives the drum (203) to rotate synchronously, thereby realizing the transfer of OCA colloid (5) wound into a cylinder. S2. The second linear motion component (4031) drives the mounting plate (402) to perform linear motion in the vertical direction through the first connecting plate (4033), causing the first half roller (4053) and the second half roller (4054) to press the OCA colloid (5) against the substrate with a certain pressure. At this time, the rotating rod (406) pushes the support plate (401) to perform linear motion in the horizontal direction, that is, pushes the first half roller (4053) and the second half roller (4054) to roll along the substrate to roll the OCA colloid (5) onto the substrate. S3. After the OCA bonding is completed, the relevant technicians can selectively activate the second linear motion component (4031) to push the pressure sensor (4032) to drive the mounting plate (402) to perform linear motion in the vertical direction until the mounting plate (402) is limited to the top inner wall of the support plate (401) by the first magnetic suction component. At this time, the second magnetic suction component is released from the limit of the mounting plate (402), and the second linear motion component (4031) is reset. At this time, the first magnetic suction component is released from the limit of the mounting plate (402), and the elastic component (4041) pulls the mounting plate (402) to perform linear motion in the vertical direction, that is, the first half roller (4053) or the second half roller (4054) impacts the substrate mounted on the automatic suction cup (301) with a certain kinetic energy, and the impact performance test is performed on the substrate that has completed the OCA bonding.

The second rotating shaft (302) pushes the automatic suction cup (301) to rotate 90 degrees, that is, it drives the substrate on which the OCA colloid (5) is installed to rotate 90 degrees, that is, it causes it to be in a vertical state. At this time, the third linear motion component (4055) correspondingly pushes the first half roller (4053) and the second half roller (4054) to perform linear motion in opposite directions. At this time, the OCA colloid (5) is located between the first half roller (4053) and the second half roller (4054). Between 4054), the third linear motion component (4055) is activated again to cause the first half roller (4053) and the second half roller (4054) to clamp the OCA colloid (5). At this time, the second linear motion component (4031) pushes the pressure sensor (4032) to drive the mounting plate (402) to perform linear motion in the vertical direction. The mounting plate (402) drives the first half roller (4053) and the second half roller (4054) to perform synchronous linear motion, that is, to pull the OCA colloid (5) attached to the substrate to gradually detach from the substrate. The pressure sensor (4032) is used to monitor the peeling force in real time and to detect the peeling force strength of the OCA colloid (5).
