Description

Technical Field

[0001] This invention relates to the field of 3C product manufacturing technology, and in particular to a pressure holding device and a pressure holding method. Background Technology

[0002] In the product assembly process of the integrated information appliance industry, which combines computers, communications, and consumer electronics, two components need to be glued together before encapsulation. Adhesive is applied to one component, and the two components are then connected using this adhesive. Generally, after the two components are pre-bonded, continuous pressure is applied to maintain the seal and ensure waterproofing between them.

[0003] Generally, adhesive needs to be applied manually to one part, then the other part is attached to the adhesive-coated part, and finally the two parts requiring pressure are placed in a pressure-holding device for pressure treatment. Manual adhesive application cannot guarantee consistent adhesive application, leading to excess adhesive between parts affecting product quality, or insufficient adhesive resulting in weak bonding. To address this, a film was applied between the two workpieces. However, this requires preheating the film to activate it before moving the parts to the pressure-holding area. This preheating process takes extra time, thus prolonging the entire pressure-holding process and reducing its efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure holding device to solve the problem of long pressure holding time and low pressure holding efficiency caused by the preheating of film.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Then, the pressure holding component performs pressure holding on the preheated product with activated film. No separate preheating is required, thereby reducing the pressure holding time of the entire pressure holding process and improving the pressure holding efficiency. Attached Figure Description

[0049] Embodiments of the present invention are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0050] Example 1

[0051] like Figures 1 to 11As shown, this embodiment provides a pressure-holding device, which includes a frame 100; a feeding assembly 200, a preheating assembly 300, a robotic arm 400, and a pressure-holding assembly 500. The feeding assembly 200 is located on the frame 100 and is used to provide a product 1000 to be pressed. The product 1000 includes a first workpiece and a second workpiece located above the first workpiece, with an adhesive film attached between the first and second workpieces. The preheating assembly 300 is located on the frame 100 and can move between a receiving position and a pressure-holding position. During the process of moving from the receiving position to the pressure-holding position, the preheating assembly 300 generates heat to heat and activate the adhesive film. The robotic arm 400 is located on the frame 100 and is used to transfer the product 1000 to be pressed from the feeding assembly 200 to the preheating assembly 300 located at the receiving position. The pressure-holding assembly 500 is located on the frame 100 and is used to press the second workpiece located at the pressure-holding position onto the first workpiece. Activation involves melting the adhesive on the film.

[0052] This pressure-holding device features a movable preheating component 300, allowing it to move between the receiving position and the pressure-holding position. Preheating begins the instant the product 1000 is placed on the preheating component 300 at the receiving position. By the time the preheating component 300 moves to the pressure-holding position, preheating is complete. Then, the pressure-holding component 500 performs pressure-holding on the preheated and activated film product 1000, eliminating the need for separate preheating. This reduces the overall pressure-holding time and improves pressure-holding efficiency.

[0053] The preheating component 300 can move along the Y direction between the receiving position and the pressure holding position.

[0054] Regarding the structure of the feeding assembly 200, in this embodiment, the feeding assembly 200 includes a feeding flow line 210, a discharging flow line 220, a lifting component 230, a picking component 240, and a support platform 250. The feeding flow line 210 is located on the frame 100 and is used to transfer the material rack 260 from the feeding position to the lifting component 230 along the X direction. Each material rack 260 is provided with at least two products 1000 to be pressed at intervals along the Z direction. The lifting component 230 is located on the frame 100 and moves along the Z direction between the feeding end and the discharging beginning. The lifting component 230 is located at the feeding end. When the material rack 260 is at the feeding end, it can receive the material rack 260 from the feeding flow line 210. When the lifting component 230 is at the unloading start end, it can move the material rack 260 to the unloading flow line 220. The unloading flow line 220 is located on the frame 100 and is used to move the material rack 260 to the unloading position along the X direction. The picking component 240 and the support platform 250 are both located on the frame 100, and the support platform 250 and the lifting component 230 are spaced apart along the Y direction. During the process of the material rack 260 moving to the unloading start end, the output end of the picking component 240 is used to move the products to be pressed 1000 one by one to the support platform 250 along the Y direction. With the above configuration, the material rack 260 completes the action of moving all the products to be pressed 1000 one by one to the support platform 250 during the process of moving from the feeding flow line 210 to the unloading flow line 220. The overall structure is simple, and the whole set of actions is smooth without any unnecessary actions, which greatly improves the smoothness and energy efficiency of the feeding process.

[0055] In this embodiment, the robot arm 400 is used to move the product 1000 to be pressed on the support platform 250 to the preheating component 300 located at the receiving position.

[0056] For example, each material rack 260 is provided with a plurality of bearing grooves 261 extending in the Y direction along the Z direction, and a product 1000 to be pressed is placed in each bearing groove 261; when the lifting member 230 is at the end of the feeding position, the bottom of the bottom bearing groove 261 is on the same side as the bearing surface of the bearing platform 250; when the lifting member 230 is at the beginning of the unloading position, the bottom of the top bearing groove 261 is on the same side as the bearing surface of the bearing platform 250. The above arrangement ensures that each rack 260 has several products 1000 to be pressed spaced along the Z direction. When the rack 260 moves from the loading flow line 210 to the lifting component 230 at the end of the loading process, the bottom surface of the lowest product 1000 to be pressed is flush with the bearing surface of the support platform 250. The picking component 240 can then pull out the lowest product 1000 to be pressed and move it onto the support platform 250. Then, the lifting component 230 descends a certain displacement, so that the bottom surface of the second product 1000 to be pressed from the bottom is flush with the bearing surface of the support platform 250. During the descent of the lifting component 230, the robotic arm 40... 0. Transfer the product 1000 to be pressed on the support platform 250 to the preheating component 300. After the lifting component 230 descends, the support platform 250 is empty. The picking component 240 pulls out the second product 1000 to be pressed and moves it to the support platform 250. This process continues until the lifting component 230 moves to the beginning of the unloading position. At this time, the bottom surface of the uppermost product 1000 to be pressed is flush with the support surface of the support platform 250. The picking component 240 moves the uppermost product 1000 to the support platform 250. Then, the lifting component 230 moves the empty material rack 260 to the unloading flow line 220.

[0057] Each rack 260 has ten or twenty support grooves 261 spaced apart. In other embodiments, the number of support grooves 261 may be greater. Optionally, the lower sidewall of the support groove 261 is provided with a roller, on which the product to be pressed 1000 is placed. The above arrangement results in rolling friction between the product to be pressed 1000 and the roller.

[0058] The feeding flow line 210 is located above the unloading flow line 220, and the feeding port is directly opposite the feeding flow line 210. The staff can place a fully loaded material rack 260 on the feeding flow line 210 from the feeding port. The feeding port is located slightly above the frame 100, which facilitates feeding and makes the feeding process safer.

[0059] An intercepting drive component 211 is disposed on the streamline support of the feeding flow line 210, and an intercepting component 212 is disposed at the output end of the intercepting drive component 211. The intercepting drive component 211 is used to drive the intercepting component 212 to move between a stop position and a yield position. When the intercepting component 212 is in the stop position, it can stop the material rack 260 on the feeding flow line 210 from moving forward. With the above configuration, the movement of the material rack 260 is hard-limited, preventing the subsequent material rack 260 from continuing to move forward under the action of inertia when the feeding flow line 210 stops.

[0060] The lifting drive component 231 is mounted on the frame 100. The output end of the lifting drive component 231 is connected to the lifting component 230 and is used to drive the lifting component 230 to move between the loading end and the unloading start end. The lifting drive component 231 is located on the side of the lifting component 230 away from the loading flow line 210.

[0061] The lifting component 230 is equipped with a transmission belt 232, which can rotate in both directions. When the lifting component 230 is at the end of the feeding process, the transmission belt 232 rotates forward, thereby receiving the material rack 260 from the feeding flow line 210. When the lifting component 230 is at the beginning of the unloading process, the transmission belt 232 rotates in reverse, thereby transferring the material rack 260 to the unloading flow line 220. The lifting component 230 is also equipped with a driving wheel, a driven wheel, and a transmission drive component. The driving wheel and the driven wheel are rotatably mounted on the lifting component 230. The transmission belt 232 is wound around the outer circumference of the driving wheel and the driven wheel. The transmission drive component is located on the lifting component 230 and is connected to the driving wheel.

[0062] In some embodiments, to ensure the stability of the material rack 260 during descent, the lifting member 230 is further provided with a fixed stop 235, a movable stop 233, and a stop drive 234. The fixed stop 235 is disposed on the lifting member 230 and located on one side of the material rack 260. The stop drive 234 is disposed on the lifting member 230 and located on the other side of the material rack 260. The movable stop 233 is disposed at the output end of the stop drive 234, and the stop drive 234 is used to drive the movable stop 233 closer to or away from the fixed stop 235. This arrangement allows the material rack 260 to be clamped between the movable stop 233 and the fixed stop 235, preventing swaying during descent and improving descent stability. A rubber pad is provided on the side of the movable stop 233 closest to the material rack 260. A rubber pad is also provided on the side of the fixed stop 235 closest to the material rack 260. In this embodiment, the hardness of the rubber pad on the fixed stop 235 is greater than the hardness of the rubber pad on the movable stop 233. This arrangement allows for effective control of the distance between the material rack 260 and the fixed stop 235, thereby improving the positional accuracy of the clamped material rack 260.

[0063] The material handling component 240 includes a clamping drive component 241, a gripper cylinder 242, and two clamping plates 243. The clamping drive component 241 is mounted on the frame 100, the gripper is located at the output end of the clamping drive component 241, and the two clamping plates 243 are respectively located at the two output ends of the gripper cylinder 242. The clamping drive component 241 drives the gripper cylinder 242 to move between a clamping position and a release position. When in the clamping position, the gripper cylinder 242 can clamp the product 1000 to be pressed located in the material rack 260 through the clamping plates 243. When in the release position, the gripper cylinder 242 can place the product 1000 to be pressed onto the support platform 250. In other embodiments, the gripper cylinder 242 and the clamping plates 243 can be replaced with suction cups. Specifically, the suction cup structure and the clamping plate 243 structure can be adapted to the structure of the first workpiece.

[0064] The support platform 250 is equipped with two rows of rollers 251. One side of the product 1000 to be pressed is placed on one row of rollers 251, and the other side is placed on the other row of rollers 251. This arrangement allows the product 1000 to be pressed to roll on the rollers 251, and the rolling friction is less than the sliding friction, effectively preventing the product 1000 to be pressed from being scratched.

[0065] The pressure-holding assembly 500 includes a first pressure-holding moving module 510, a second pressure-holding moving module 520, a pressure-holding seat 530, and a pressure-holding head 540. The first pressure-holding moving module 510 is mounted on the frame 100, the second pressure-holding moving module 520 is located at the output end of the first pressure-holding moving module 510, the pressure-holding seat 530 is located at the output end of the second pressure-holding moving module 520, and the pressure-holding head 540 is floatingly mounted on the pressure-holding seat 530. The output end of the first pressure-holding moving module 510 can move along the X direction, and the output end of the second pressure-holding moving module 520 can move along the Z direction. This arrangement allows the pressure-holding head 540 and the product 1000 to be pressed to move relative to each other in three-dimensional space, thereby enabling the pressure-holding head 540 to accurately press down on the product 1000.

[0066] In some embodiments, at least two second workpieces are provided, each located above the first workpiece, and a film is provided between each second workpiece and the first workpiece. The pressure-holding assembly 500 has at least two pressure-holding heads 540, which are independently and spaced apart from each other, and correspond one-to-one with the at least two second workpieces. The independent pressure-holding heads 540 ensure that each second workpiece is subjected to pressure, preventing overpressure or underpressure in any one second workpiece and improving the success rate of pressure holding.

[0067] Regarding the mechanism of the pressure-holding seat 530, in this embodiment, the pressure-holding seat 530 includes a connecting seat 531, a fixed seat 532, and a mounting seat 533. The fixed seat 532 is provided with a receiving groove 5321, and the mounting seat 533 is provided with a mounting groove 5331 and a sliding channel 5332 communicating with the mounting groove 5331. The sliding channel 5332 and the receiving groove 5321 are arranged in a one-to-one correspondence. The fixed seat 532 is connected to the connecting seat 531, and the mounting seat 533 is connected to the fixed seat 532, forming a mounting cavity between the fixed seat 532 and the mounting seat 533. The pressure-holding head 540 is slidably disposed in the sliding channel 5332. One end of the first elastic member 542 is connected to the pressure-holding head 540, and the other end is located in the receiving groove 5321. The pressure-holding head 540 moves between an extended position and a retracted position, and the first elastic member 542 is used to drive the pressure-holding head 540 to stop at the extended position. The pressure-holding head 540, located in the pressure-holding position, can press the product 1000 to be pressed, which is located in the pressure-holding position. The pressure-holding position is between the extended position and the retracted position. This arrangement ensures that the pressure of the pressure-holding head 540 is provided by the first elastic element 542, avoiding overpressure that could damage the second or even the first workpiece. In this embodiment, the first elastic element 542 is a spring. One end of the pressure-holding head 540, located in the mounting cavity, is connected to a fixing block 541. The outer diameter of the fixing block 541 is larger than the outer diameter of the sliding channel 5332 and larger than the inner diameter of the spring. The end of the fixing block 541 away from the pressure-holding head 540 has a connecting protrusion. One end of the spring is fitted onto the connecting protrusion, and the other end passes through the receiving groove 5321. The above arrangement prevents the pressure-holding head 540 from being pulled out of the sliding channel 5332.

[0068] To prevent heat from being transferred to the second movable pressure holding module during the pressure holding process, in some embodiments, the pressure holding base 530 further includes a heat insulation plate 534, which is disposed between the connecting base 531 and the fixed base 532.

[0069] An adapter plate is positioned between the heat insulation plate 534 and the mounting base 532 to facilitate the connection between them. The mounting cavity reduces the heat dissipation rate, thereby decreasing the heat transferred to the heat insulation plate 534, lowering the size or weight requirements for the heat insulation plate 534, and reducing costs. Furthermore, the adapter plate allows the receiving groove 5321 on the mounting base 532 to be replaced with a through-hole structure, enabling the first elastic element 542 to directly press against the adapter plate. This simplifies the machining of the receiving hole and improves the machining efficiency of the mounting base 532.

[0070] In this embodiment, the first workpiece is the first PCB, the second workpiece is the second PCB, and the shape of the pressure head of the pressure head 540 is the same as the shape of the second PCB.

[0071] The preheating assembly 300 includes a preheating moving module 310, a preheating rotating module 320, a preheating platform 330, and a pressing assembly 340. The preheating rotating module 320 is located at the output end of the preheating moving module 310, and the preheating platform 330 is located at the output end of the preheating rotating module 320. The preheating platform 330 has an internal thermocouple for generating heat. The pressing assembly 340 is located on the preheating platform 330 and is used to press the product 1000 to be pressed against the preheating platform 330. The output end of the preheating moving module 310 can move along the Y direction, and the output end of the preheating rotating module 320 can rotate around the Z direction. With the above configuration, the angle of position transfer of the product 1000 to be pressed can be adjusted, thereby making the pressure of the pressure holding head 540 and the second workpiece more precise.

[0072] In this embodiment, a heat insulation platform 350 is provided between the preheating platform 330 and the preheating rotary module 320 to prevent heat from the preheating platform 330 from being transferred to the preheating rotary module 320, thereby improving heat utilization and avoiding heat waste. Furthermore, heat insulation components 360 are provided around the preheating platform 330 to reduce heat dissipation from the preheating platform 330 to the surroundings, further preventing heat waste and improving heat utilization. The heat insulation components 360 are disposed on the heat insulation platform 350, and the heat insulation platform 350 and the heat insulation components 360 form a heat insulation groove, within which the preheating platform 330 is located.

[0073] In some embodiments, the preheating platform 330 has a square structure, with at least two temperature sensors on each side to monitor and adjust the temperature of each part in real time, so that the temperature of the preheating platform 330 is always maintained within a preset heating temperature range, ensuring that each film can be heated and activated. Multiple thermocouples are provided, distributed throughout the preheating platform 330.

[0074] The preheating platform 330 is equipped with suction holes for adsorbing the product 1000 to be pressed. There are at least three sets of suction holes, and the preheating platform 330 has at least three independent air paths, each corresponding to a set of suction holes. This arrangement effectively ensures the adsorption of the product 1000 to be pressed. For example, the three sets of suction holes are defined as a first set, a second set, and a third set. The first set has at least four suction holes, located on the four sides of the preheating platform 330; the second set has at least four suction holes, located on the four sides of the preheating platform 330; and the third set has at least four suction holes, located on the four sides of the preheating platform 330. Even if only one set of suction holes functions properly, a secure connection of the product 1000 to be pressed on the preheating platform 330 can be guaranteed.

[0075] The clamping assembly 340 includes a clamping drive 341, a clamping rotating rod 342, a lever 343, a second elastic element 344, and a clamping element 345. The clamping drive 341 is disposed on the preheating platform 330. The clamping rotating rod 342 is rotatably disposed on the preheating platform 330 and is connected to the output end of the clamping drive 341. The lever 343 is fixedly disposed on the clamping rotating rod 342. One end of the clamping element 345 is hinged to the lever 343, and the other end is used to press the product 1000 to be pressed. The second elastic element 344 is disposed between the lever 343 and the clamping element 345 and is used to drive the clamping element 345 to press against the product 1000 to be pressed. The pressing drive 341 drives the pressing rotating rod 342 to rotate, thereby driving the lever 343 to rotate. When the lever 343 rotates above the product to be pressed 1000, under the action of the second elastic member 344, the other end of the pressing member 345 presses the product to be pressed 1000.

[0076] To prevent foreign matter from being present on the second workpiece during ballast loading, which could cause indentations or damage during pressure holding, this embodiment of the pressure holding device also includes a blower 370. The blower 370 is mounted on the frame 100 and is used to blow ion air onto the product 1000 to be pressured in the pressure holding position.

[0077] To further improve the alignment accuracy of the pressure-holding head 540 and the second workpiece, in this embodiment, the pressure-holding device also includes a lower CCD camera 560 and an upper CCD camera 550. The lower CCD camera 560 is mounted on the frame 100 and is used to photograph the pressure-holding head 540 from above to obtain its position. The upper CCD camera 550 is mounted at the output end of the first pressure-holding moving module 510 and is used to photograph the second workpiece and the first workpiece from below to obtain the position of the second workpiece relative to the first workpiece. The working principle of the CCD camera is well known to those skilled in the art and will not be described in detail here.

[0078] To improve pressure holding efficiency, two pressure holding components 500 are provided. The pressure holding head 540 of the pressure holding component 500 can move between the pressure holding position and the avoidance position. Two preheating components 300 are provided, each corresponding to one of the two pressure holding components 500. The avoidance position is located between the two pressure holding positions, and the lower CCD camera 560 is located in the avoidance position to capture images of the pressure holding heads 540 of the two pressure holding components 500. The above setup can simultaneously pressure two products 1000 to be pressured. In addition, when the product 1000 to be pressured is removed after pressure holding is completed, the pressure holding head 540 needs to be removed. During this process, the pressure holding head 540 needs to be moved to the position of the lower CCD camera 560 to complete the position calibration.

[0079] The pressure holding equipment also includes a finished product flow line, a transfer moving part, a pushing part, and a finished product platform located on the frame 100. After the product to be pressed 1000 completes the pressure holding, it is moved to the receiving position by the preheating component 300. The robot arm 400 moves the product to be pressed 1000 that has completed the pressure holding to the finished product platform. The transfer moving part is raised and lowered along the Z direction on the frame 100 and can move between the finished product receiving position and the finished product transfer position. The pushing part can push the product to be pressed 1000 onto the transfer moving part located at the finished product receiving position. The transfer moving part descends to the finished product transfer position and moves the product to be pressed 1000 onto the finished product flow line. The finished product flow line moves the product to be pressed 1000 that has completed the pressure holding to the outside of the equipment.

[0080] The transfer moving component is equipped with a transfer flow line that can rotate in the X direction. When the transfer moving component moves to the finished product transfer position, the transfer flow line is activated, causing the product to be pressed 1000 to move onto the finished product flow line.

[0081] In this embodiment, the transfer moving component is driven by a transfer Z-axis linear module. Fixed clamping components and movable clamping components are respectively provided on both sides of the transfer streamline. The movable clamping components can move closer to or further away from the fixed clamping components, and the product 1000 to be pressed on the transfer streamline can be clamped between the fixed clamping components and the movable clamping components. The movable clamping components are connected to a driving component fixed on the transfer moving component.

[0082] In this embodiment, any two of the X, Y, and Z directions are perpendicular to each other.

[0083] Example 2

[0084] This embodiment also provides a pressure holding method, including a pressure holding device suitable for the above-described scheme, the pressure holding method comprising the following steps:

[0085] S1. The robot arm 400 moves the product to be pressed 1000 located in the feeding component 200 to the preheating component 300 located in the receiving position. The product to be pressed 1000 includes a first workpiece, a second workpiece, and a film sandwiched between the first workpiece and the second workpiece.

[0086] S2. During the process of the preheating component 300 moving to the pressure holding position, the film between the first workpiece and the second workpiece is heated and activated.

[0087] S3. The pressure-holding assembly 500 presses the second workpiece against the first workpiece and maintains pressure for a preset time. This method allows the film to be heated and activated during the transfer of the product to be pressed 1000 by the preheating assembly 300. When the product to be pressed 1000 moves to the pressure-holding position, pressure can be held directly, improving pressure-holding efficiency. The preset time can be 60 seconds.

[0088] Because the material rack 260 is provided with multiple bearing grooves 261 spaced along the Z direction, and each bearing groove 261 holds a product 1000 to be pressed, the feeding assembly 200 transfers the material rack 260 to the lifting component 230. During the descent of the lifting component 230, the picking component 240 sequentially removes the product 1000 to be pressed and moves it to the bearing platform 250. The entire process is simply the material rack 260 moving from the feeding assembly 200 to the unloading flow line 220, with no redundant structural settings, simplified process, and improved material picking efficiency.

[0089] The material rack 260 has multiple bearing grooves 261 on each side. The bearing grooves 261 on both sides correspond one to one, and the openings of the two bearing grooves 261 in each group are arranged opposite each other. The two sides of the product to be pressed 1000 are placed in the two bearing grooves 261 respectively.

[0090] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
