Description

Technical Field

[0001] This invention relates to the field of coating technology, specifically to an electronic product coating device and an electronic product coating method. Background Technology

[0002] Currently, most electronic products on the market are wrapped in film after the production and packaging processes are completed, to provide more comprehensive protection for the products. This measure is of great significance, as it effectively prevents the packaging box from being worn down by friction and collision during transportation, storage, and sales display, and also prevents dust and stains from adhering, keeping the packaging box clean and beautiful.

[0003] A search revealed a utility model patent with Chinese patent publication number CN211443030U, which discloses a cutting device for a film wrapping machine. The device includes a support frame, an electric telescopic rod fixedly connected to the inner side of the top surface of the support frame, a support plate fixedly connected to the bottom surface of the electric telescopic rod, a sleeve plate fixedly connected to the bottom surface of the support plate, an inner plate slidably connected to the bottom inner side of the sleeve plate, and the inner plate penetrating the sleeve plate, a fixing frame fixedly connected to the center position of the bottom surface of the support plate, and a resistance wire fixedly connected to the bottom inner side of the fixing frame.

[0004] The aforementioned device uses a thermal cutting method to separate the membrane material used for wrapping from the main membrane material. However, during the actual pressing wrapping operation, the membrane is pressed onto the outside of the product in an expanded state. As a result, air will be trapped between the membrane and the product. Moreover, since it is an overall covering type of pressing, this air cannot be expelled smoothly. If too much air accumulates inside the membrane during the wrapping process, the membrane will rupture due to expansion, ultimately causing the wrapping to fail. There is still room for improvement. Summary of the Invention

[0005] The purpose of this invention is to provide an electronic product coating apparatus and an electronic product coating method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electronic product coating device and an electronic product coating method, comprising a base plate, a receiving frame fixedly connected to one side of the top outer wall of the base plate, a laser control component fixedly connected to the receiving frame, a first roller conveyor and a second roller conveyor fixedly connected to the other side of the top outer wall of the base plate, the receiving frame facing the inlet of the second roller conveyor, a dividing component fixedly connected to the top outer wall of the receiving frame, the dividing component including a mounting frame fixedly connected to the top outer wall of the receiving frame, and a vertical [unclear - possibly a component or element] fixedly connected to the top outer wall of the mounting frame. A telescopic electric cylinder is provided, with a mounting plate fixedly connected to its output end. A movable plate is fixedly connected to the bottom outer wall of the mounting plate, and four telescopic rods are fixedly connected to the bottom outer wall of the movable plate. A common abutment block is fixedly connected to one end of each of the four telescopic rods. Four extrusion structures are fixedly connected to the top of the abutment block to expel air around the electronic product. A dividing cutter is fixedly connected to the top of the abutment block to divide the film around the electronic product. A reversing assembly is fixedly connected to the top of the base plate to push the electronic product toward the second roller conveyor.

[0007] As a further preferred embodiment of this technical solution, the extrusion structure includes an extension frame fixedly connected to the top of the abutment block. Two symmetrically arranged mounting arms are slidably connected inside the extension frame. A horizontally arranged first bidirectional lead screw is rotatably connected inside the extension frame. The two mounting arms are threaded to the outside of the threaded grooves at both ends of the first bidirectional lead screw. An airbag is fixedly connected to the middle position of the outer wall of one end of the extension frame at the ends of the two mounting arms that are far apart from each other. An air tank is fixedly connected to the top outer wall of each of the three airbag mounting ends. A piston rod is slidably connected inside each of the three air tanks. A spring is fixedly connected to the bottom outer wall of each of the three piston rods.

[0008] As a further preferred embodiment of this technical solution, the dividing cutter includes four guide rods fixedly connected to the outer wall of the top of the abutment block. The four guide rods are slidably connected to the same fixing frame. The bottom outer wall of the fixing frame is fixedly connected to an annular hot cutting blade. The annular hot cutting blade surrounds the outside of the abutment block. The same spring is sleeved on the outside of each of the four guide rods.

[0009] Before the membrane material is separated from the main material, it can automatically expel the air around the product and adapt to the shape of the product box, effectively preventing the membrane material from cracking during subsequent shrinkage. The telescopic electric cylinder drives the moving plate downward through the mounting plate. Then, the abutment block contacts the top wall of the electronic product and can no longer move downward. The moving plate will continue to move downward, and the extension frame fixed outside the abutment block can no longer move downward. Then, the moving plate applies pressure to the piston rod, and the air inside the air tank is injected into the airbag. The airbag begins to expand. Under the combined compression of the twelve airbags located at the edge of the product, the membrane will be squeezed to fit the product surface. The air overflows out through the gap between two adjacent airbags. Finally, the moving plate moves down and contacts the fixing frame. The fixing frame is pushed down along the four guide rods. The heated annular hot cutter installed on the fixing frame, together with the blade pad on the top of the receiving frame, can complete the membrane material separation.

[0010] As a further preferred embodiment of this technical solution, a guide assembly is fixedly connected to the side of the top outer wall of the base plate away from the receiving frame, and a wrapping assembly is provided on the side of the top outer wall of the base plate close to the receiving frame. The wrapping assembly includes a take-up roller and an unwind roller rotatably connected inside the first roller conveyor. The take-up roller and the unwind roller are respectively located at the upper and lower positions on one side of the first roller conveyor. Two guide posts are rotatably connected inside the first roller conveyor, and the two guide posts are located in the middle of the take-up roller and the unwind roller. A guide post is rotatably connected inside the receiving frame, and the guide post is located on the side away from the first roller conveyor. The heat-shrinkable film on the unwind roller passes around the two guide posts and the guide post and is fixedly connected to the take-up roller. Two motors are fixedly connected to the outer wall on one side of the first roller conveyor, and the two motors are respectively coaxially fixed with the rotating shafts of the take-up roller and the unwind roller.

[0011] The electronic product is then moved towards the receiving frame by the first roller conveyor, and then enters the film chamber formed by two guide pillars. The electronic product first blocks the laser emitted by the first laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller and unwind roller run simultaneously, and the film is driven to start transmission. The electronic product on it continues to move. Then it blocks the laser emitted by the second laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller and unwind roller stop running, and at the same time, the telescopic electric cylinder also starts to operate, thus completing the film segmentation. The electronic product will be completely wrapped in the film, enabling continuous processing.

[0012] As a further preferred embodiment of this technical solution, the guide assembly includes a limiting frame fixedly connected to the top outer wall of the base plate. A cross groove is provided inside the limiting frame, and two moving blocks are slidably connected inside the cross groove. A guide plate is fixedly connected to the bottom outer wall of each of the two moving blocks. The two guide plates are symmetrically arranged about the limiting frame. A second bidirectional lead screw is rotatably connected inside the cross groove, and the two moving blocks are respectively threaded to the outside of the threaded grooves at both ends of the second bidirectional lead screw.

[0013] As a further preferred embodiment of this technical solution, the reversing assembly includes a guide frame fixedly connected to the top outer wall of the base plate, a slider slidably connected to the outside of the guide frame, a connecting rod rotatably connected to the outside of the slider, a push plate rotatably connected to the top end of the connecting rod, a limit groove is formed on the top outer wall of the receiving frame, the push plate is slidably connected inside the limit groove, and a drive structure is fixedly connected to the outside of the mounting plate.

[0014] As a further preferred embodiment of this technical solution, the driving structure includes an extension rod fixedly connected to the outside of the mounting plate. A horizontally arranged sliding groove is provided at one bottom end of the extension rod. A hook plate is slidably connected inside the sliding groove and contacts the slider. A guide groove is fixedly connected to the bottom of one side of the outer wall of the guide frame. One top end of the guide groove is inclined towards the extension rod, and the rotating end of the hook plate extends into the guide groove.

[0015] As a further preferred embodiment of this technical solution, a guide bucket is fixedly connected to the outer wall of the receiving frame near one end of the second roller conveyor, and an installation cover is fixedly connected to the top outer wall of the second roller conveyor. An inlet is opened on the outer wall of the installation cover near the guide bucket, and resistance wires are fixedly connected inside the installation cover and inside the first roller conveyor.

[0016] When the telescopic electric cylinder begins to retract, the extension rod is driven to move upward synchronously. The hook plate, which slides inside the chute at one end, is supported by the extension rod and cannot be flipped downward. The extension rod then hooks the slider upward through the hook plate. The slider drives the bottom end of the connecting rod to move synchronously. The connecting rod can then push the push plate to slide inside the limiting groove inside the receiving frame. The push plate can then push the wrapped electronic product to one side, and then into the discharge chute on one side of the receiving frame, and then into the second roller conveyor. The resistance wire of the cover mounted on the top of the second roller conveyor is energized and heated. When the electronic product is conveyed outward, the film will shrink and tightly wrap around the outside of the electronic product. Finally, it is conveyed to the operator's side, which can realize continuous processing at a single station, which helps to save labor costs.

[0017] As a further preferred embodiment of this technical solution, the laser control assembly includes two laser emitters and two laser receivers. The two laser emitters are both located on the top of the receiving frame and are arranged sequentially along the moving direction of the electronic products conveyed by the first roller conveyor. The two laser receivers are respectively arranged corresponding to the two laser emitters, and both laser receivers are electrically connected to the motors of the drive take-up roller and the unwind roller.

[0018] As a further preferred embodiment of this technical solution, the annular hot cutting blade is arranged in the shape of a rectangular ring, and the corners of the rectangular ring are all rounded.

[0019] This invention provides an electronic product coating device and an electronic product coating method, which have the following beneficial effects: (1) By setting up a segmentation component, the present invention can squeeze out the air around the product before the film material is separated from the main material, and can adapt to the shape of the product box, effectively avoiding the film material from cracking when it shrinks later. The telescopic electric cylinder drives the moving plate to move downward through the mounting plate. Then the abutting block contacts the top wall of the electronic product and can no longer move downward. The moving plate will continue to move downward. The extension frame fixed outside the abutting block can no longer move downward. Then the moving plate applies pressure to the piston rod. The air inside the air tank is injected into the airbag. The airbag volume begins to expand. Under the combined squeezing of the twelve airbags located at the edge of the product, the film will be squeezed to fit the product surface. The air overflows out through the gap between two adjacent airbags. Finally, the moving plate moves down and contacts the fixing frame. The fixing frame is pushed down along the four guide rods. The annular hot cutting knife installed on the fixing frame and the top knife pad of the receiving frame can complete the segmentation of the film material.

[0020] (2) By setting up a film-coating assembly, the electronic product is then driven by the first roller conveyor to move towards the receiving frame, and then enters the film cavity formed by the two guide pillars 1 and 2. The electronic product first blocks the laser emitted by the first laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller and the unwind roller run simultaneously, and the film is driven to start transmission. The electronic product on it is driven to continue moving. Then it blocks the laser emitted by the second laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller and the unwind roller stop running, and at the same time, the telescopic electric cylinder also starts to run, thereby completing the film segmentation. The electronic product will be completely wrapped by the film, which can realize continuous processing.

[0021] (3) By setting up a reversing component and a second roller conveyor, when the telescopic electric cylinder begins to retract, the extension rod is driven to move upward synchronously. The hook plate, which slides inside the chute at one end, is supported by the extension rod and cannot be flipped downward. The extension rod will hook the slider upward through the hook plate. The slider drives the bottom end of the connecting rod to move synchronously. The connecting rod can push the push plate to slide inside the limiting groove inside the receiving frame. The push plate can push the wrapped electronic product to one side, and then enter the discharge chute on one side of the receiving frame, and then enter the second roller conveyor. The resistance wire of the cover installed on the top of the second roller conveyor is energized and heated. When the electronic product is conveyed outward, the film will shrink and tightly wrap around the outside of the electronic product. Finally, it is conveyed to the operator's side, which can realize continuous processing at a single station and is conducive to saving labor costs. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] This invention provides a technical solution: such as Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, the electronic product coating device and electronic product coating method include a base plate 1. A receiving frame 4 is fixedly connected to one side of the top outer wall of the base plate 1. A laser control component is fixedly connected to the receiving frame 4. A first roller conveyor 2 and a second roller conveyor 3 are fixedly connected to the other side of the top outer wall of the base plate 1. The receiving frame 4 faces the inlet of the second roller conveyor 3. A dividing component 5 is fixedly connected to the top outer wall of the receiving frame 4. The dividing component 5 includes a mounting frame 501 fixedly connected to the top outer wall of the receiving frame 4. A vertically arranged telescopic electric cylinder 502 is fixedly connected to the top outer wall of the mounting frame 501. A mounting plate 503 is fixedly connected to the output end of cylinder 502. A movable plate 504 is fixedly connected to the bottom outer wall of the mounting plate 503. Four telescopic rods 505 are fixedly connected to the bottom outer wall of the movable plate 504. The same abutment block 506 is fixedly connected to one end of the bottom of the four telescopic rods 505. Four extrusion structures are fixedly connected to the top of the abutment block 506 to expel air around the electronic product. A dividing cutter is fixedly connected to the top of the abutment block 506 to divide the film around the electronic product. A reversing assembly 8 is fixedly connected to the top of the base plate 1 to push the electronic product toward the direction of the second roller conveyor 3.

[0025] The extrusion structure includes an extension frame 507 fixedly connected to the top of the abutment block 506. Two symmetrically arranged mounting arms 509 are slidably connected inside the extension frame 507. A horizontally arranged first bidirectional lead screw 508 is rotatably connected inside the extension frame 507. The two mounting arms 509 are threaded to the outside of the threaded grooves at both ends of the first bidirectional lead screw 508. (If other products need to be replaced, the positions of the two mounting arms 509 inside the extension frame 507 can be adjusted to adapt to the exhaust work of products of different sizes. The extension frame 507 can be individually removed from the abutment block 506 for reuse.) An airbag 510 is fixedly connected to the ends of the two mounting arms 509 that are far apart from each other and to the middle of the outer wall of one end of the extension frame 507. An air tank 511 is fixedly connected to the top outer wall of each of the three airbags 510. A piston rod 512 is slidably connected inside each of the three air tanks 511. A spring 513 is fixedly connected to the bottom outer wall of each of the three piston rods 512.

[0026] The dividing tool includes four guide rods 514 fixedly connected to the top outer wall of the abutment block 506. The four guide rods 514 are slidably connected to the same fixing frame 516. The bottom outer wall of the fixing frame 516 is fixedly connected to an annular hot cutting blade 517. The annular hot cutting blade 517 surrounds the outside of the abutment block 506. The same spring 515 is sleeved on the outside of each of the four guide rods 514.

[0027] The telescopic electric cylinder 502 drives the moving plate 504 downward via the mounting plate 503. Subsequently, the abutment block 506 contacts the top wall of the electronic product and can no longer move downward. The moving plate 504 continues to move downward, and the extension frame 507 fixed outside the abutment block 506 also cannot move downward. Then, the moving plate 504 applies pressure to the piston rod 512, and air from the air tank 511 is injected into the airbag 510. The airbag 510 begins to expand. Under the combined compression of the twelve airbags 510 located at the edge of the product, the film is squeezed and adheres to the product surface. The air overflows outward through the gap between two adjacent airbags 510. Finally, the moving plate 504 moves down and contacts the fixed frame 516. The fixed frame 516 is pushed down along the four guide rods 514. The annular hot cutting blade 517, which is heated and installed on the fixed frame 516, works with the top blade pad of the receiving frame 4 to complete the cutting of the membrane material. After the action is completed, the telescopic electric cylinder 502 begins to retract, driving the mounting plate 503 to move up. The compressed spring 1 513 and spring 2 515 return to their length. The piston rod 512 and the fixed frame 516 are pushed upward respectively to prepare for the next operation.

[0028] like Figure 1 and Figure 3 As shown, a guide assembly 7 is fixedly connected to the side of the top outer wall of the base plate 1 away from the receiving frame 4. A wrapping assembly 6 is provided on the side of the top outer wall of the base plate 1 near the receiving frame 4. The wrapping assembly 6 includes a take-up roller 601 and an unwind roller 602 rotatably connected inside the first roller conveyor 2. The take-up roller 601 and the unwind roller 602 are located at the upper and lower positions on one side of the first roller conveyor 2, respectively. Two guide posts 603 are rotatably connected inside the first roller conveyor 2. The two guide posts 603 are located in the middle position between the take-up roller 601 and the unwind roller 602. A guide post 604 is rotatably connected inside the receiving frame 4. The guide post 604 is located on the side away from the first roller conveyor 2. The heat-shrinkable film on the unwind roller 602 passes around the two guide posts 603 and the guide post 604 in sequence and is fixedly connected to the take-up roller 601. Two motors are fixedly connected to the outer wall on one side of the first roller conveyor 2. The two motors are coaxially fixed with the rotating shafts of the take-up roller 601 and the unwind roller 602, respectively.

[0029] The electronic product is moved towards the receiving frame 4 by the first roller conveyor 2, and then enters the film chamber formed by the two guide pillars 603 and 604. The electronic product first blocks the laser emitted by the first laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller 601 and the unwind roller 602 run simultaneously, and the film is driven to start transmission. The electronic product on it is driven to continue moving. Then it blocks the laser emitted by the second laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller 601 and the unwind roller 602 stop running. At the same time, the telescopic electric cylinder 502 also starts to run, thereby completing the film segmentation. The electronic product will be completely wrapped by the film, which can realize continuous processing, with simple structure and high processing efficiency. The remaining scraps will be rolled up in the next processing.

[0030] The laser control assembly includes two laser emitters and two laser receivers. The two laser emitters are both located on the top of the receiving frame 4 (not shown in the figure) and are arranged sequentially along the moving direction of the electronic products conveyed by the first roller conveyor 2. The two laser receivers are respectively set to correspond to the two laser emitters. Both laser receivers are electrically connected to the motors that drive the take-up roller 601 and the unwind roller 602.

[0031] like Figure 1 As shown in Figure 2, the guide assembly 7 includes a limiting frame 701 fixedly connected to the top outer wall of the base plate 1. A cross groove is provided inside the limiting frame 701. Two moving blocks 702 are slidably connected inside the cross groove. A guide plate 704 is fixedly connected to the bottom outer wall of each of the two moving blocks 702. The two guide plates 704 are symmetrically arranged about the limiting frame 701. A second bidirectional lead screw 703 is rotatably connected inside the cross groove. The two moving blocks 702 are respectively threaded to the outside of the threaded grooves at both ends of the second bidirectional lead screw 703.

[0032] According to the size adjustment guide assembly 7 after the electronic product is packaged, the second bidirectional lead screw 703 is driven to rotate inside the limiting frame 701. The moving block 702, which is slidably connected inside the limiting frame 701, cannot rotate. The second bidirectional lead screw 703 can then drive the two moving blocks 702 to move towards each other inside the limiting frame 701. The guide plate 704 fixed to the bottom of the moving block 702 will also move synchronously. Since the extended part of the guide plate 704 is set in a direction away from the first roller conveyor 2, when the electronic product is placed between the two guide plates 704, it will be guided by the two guide plates 704 to move towards the middle position of the first roller conveyor 2. This helps to ensure the accuracy of the position of subsequent products, thereby ensuring the quality of the wrapping.

[0033] like Figure 2 , Figure 7 and Figure 8As shown, the reversing assembly 8 includes a guide frame 803 fixedly connected to the top outer wall of the base plate 1, a slider 804 slidably connected to the outside of the guide frame 803, a connecting rod 802 rotatably connected to the outside of the slider 804, a push plate 801 rotatably connected to the top end of the connecting rod 802, a limit groove is opened on the top outer wall of the receiving frame 4, the push plate 801 is slidably connected inside the limit groove, and a drive structure is fixedly connected to the outside of the mounting plate 503.

[0034] The driving structure includes an extension rod 805 fixedly connected to the outside of the mounting plate 503. A horizontally positioned groove 806 is formed at one bottom end of the extension rod 805. A hook plate 807 is slidably connected inside the groove 806, contacting the slider 804. A guide groove 808 is fixedly connected to the bottom of one side of the guide frame 803. The top end of the guide groove 808 is inclined towards the extension rod 805, and the rotating end of the hook plate 807 extends into the guide groove 808. When the hook plate 807 is moved upward by the extension rod 805, the sliding part of the hook plate 807 enters the inclined groove at the top of the guide groove 808, guiding it to slide into the groove 806. Subsequently, the slider 804 is no longer supported and resets under gravity. Furthermore, when the hook plate 807 is moved downward and contacts the slider 804, it can flip upward without obstruction, allowing it to move normally below the slider 804.

[0035] A guide bucket is fixedly connected to the outer wall of the receiving frame 4 near the second roller conveyor 3. An installation cover is fixedly connected to the top outer wall of the second roller conveyor 3. An inlet is opened on the outer wall of the installation cover near the guide bucket. Resistance wires are fixedly connected inside the installation cover and inside the first roller conveyor 2.

[0036] When the telescopic cylinder 502 begins to retract, the extension rod 805 is driven to move upward synchronously. The hook plate 807, which slides inside the slide groove 806 at one end, is supported by the extension rod 805 and cannot be flipped downward. The extension rod 805 will hook the slider 804 upward through the hook plate 807. The slider 804 drives the bottom end of the connecting rod 802 to move synchronously. The connecting rod 802 can then push the push plate 801 to slide inside the limiting groove inside the receiving frame 4. The push plate 801 can push the wrapped electronic product to one side, and then enter the discharge groove on one side of the receiving frame 4, and then enter the second roller conveyor 3. The resistance wire of the cover installed on the top of the second roller conveyor 3 is energized and heated. When the electronic product is conveyed outward, the film will shrink and tightly wrap the outside of the electronic product. Finally, it is conveyed to the operator's side, which can realize continuous processing at a single station, which is conducive to saving labor costs.

[0037] like Figure 4 and Figure 5As shown, the annular hot cutting blade 517 is arranged in a rectangular ring, and the corners of the rectangular ring are all rounded, so that the corners of the cut film are arc-shaped. When it is subsequently heated and shrunk, there will be no sharp points that affect the appearance.

[0038] According to another aspect of this disclosure, a method for coating electronic products is also provided, which involves coating an electronic product using the electronic product coating apparatus described above, comprising: Step 1: Adjust the guide assembly 7 according to the size of the electronic product so that the two guide plates 704 can make perfect contact with the outer walls on both sides of the electronic product; Step 2: Select the corresponding size movable plate 504 according to the size of the electronic product, and connect and fix it to the mounting plate 503 using bolts; Step 3: Pull the film on the unwinding roller 602 upwards, first from top to bottom around the bottom guide post 603, then from bottom to top around the guide post 604, then from bottom to top around the top guide post 603, and finally fix the film to the outside of the take-up roller 601. Step 4: Place the electronic product on top of the first roller conveyor 2 and transfer the electronic product into the cavity formed by the coating assembly. Trigger two laser limit switches in sequence. The two limit switches first control the film transmission and then control the operation of the dividing assembly 5. Step 5: The segmentation component 5 first fixes the position of the electronic product, then squeezes out the air around the product, and finally completes the segmentation of the main film, so that the electronic product will be completely wrapped up. Step 6: During the resetting process of the dividing component 5, the reversing component 8 is driven to run, pushing the wrapped product into the second roller conveyor 3; Step 7: The product is conveyed towards the operator by the second roller conveyor 3. During this process, the resistance wire inside the second roller conveyor 3 heats up, causing the heat-shrink film wrapped around the product to shrink and adhere tightly to the outer surface of the product. Finally, the product is conveyed to the operator's side.

[0039] This invention provides an electronic product coating device and an electronic product coating method, the specific working principle of which is as follows: When the device is working, the guide assembly 7 is adjusted according to the size of the packaged electronic product, which drives the second bidirectional lead screw 703 to rotate inside the limiting frame 701. The moving block 702, which is slidably connected inside the limiting frame 701, cannot rotate. The second bidirectional lead screw 703 can then drive the two moving blocks 702 to move towards each other inside the limiting frame 701. The guide plate 704, which is fixed to the bottom of the moving block 702, will also move synchronously. Since the extended part of the guide plate 704 is set in a direction away from the first roller conveyor 2, when the electronic product is placed between the two guide plates 704, it will be guided by the two guide plates 704 to move towards the middle position of the first roller conveyor 2. This helps to ensure the accuracy of the position of subsequent products, thereby ensuring the quality of the wrapping.

[0040] Subsequently, the electronic product is moved towards the receiving frame 4 by the first roller conveyor 2, and then enters the film cavity formed by the two guide pillars 603 and 604. The electronic product first blocks the laser emitted by the first laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller 601 and the unwind roller 602 run simultaneously, and the film is driven to start transmission. The electronic product on it is driven to continue moving. Then, it blocks the laser emitted by the second laser emitter, and the corresponding receiver does not receive the laser signal. The motors driving the take-up roller 601 and the unwind roller 602 stop running. At the same time, the telescopic electric cylinder 502 also starts to run, thereby completing the film segmentation. The electronic product will be completely wrapped in the film, which can realize continuous processing, with simple structure and high processing efficiency. The remaining scraps will be rolled up in the next processing.

[0041] When the telescopic cylinder 502 begins to retract, the extension rod 805 is driven to move upward synchronously. The hook plate 807, which slides inside the slide groove 806 at one end, is supported by the extension rod 805 and cannot flip downward. The extension rod 805 then hooks the slider 804 upward through the hook plate 807. The slider 804 drives the bottom end of the connecting rod 802 to move synchronously. The connecting rod 802 can then push the push plate 801 to slide inside the limiting groove inside the receiving frame 4. The push plate 801 can push the wrapped electronic product to one side, and then into the discharge chute on one side of the receiving frame 4, and then into the second roller conveyor 3. The resistance wire of the cover mounted on the top of the second roller conveyor 3 is energized and heated. When the electronic product is pushed outward... During transport, the film shrinks and tightly wraps around the outside of the electronic product before being transported to the operator's side. This enables continuous processing at a single station, saving labor costs. When the hook plate 807 is moved upward by the extension rod 805, the sliding part of the hook plate 807 enters the inclined groove at the top of the guide groove 808. The hook plate 807 is guided to slide into the slide groove 806. Subsequently, the slider 804 is no longer supported and resets under gravity. In addition, when the hook plate 807 is moved downward and contacts the slider 804, it can flip upward normally without obstruction, allowing it to move normally below the slider 804.

[0042] The segmentation process is as follows: The telescopic electric cylinder 502 drives the moving plate 504 downward via the mounting plate 503. Subsequently, the abutment block 506 contacts the top wall of the electronic product and cannot move further downward. The moving plate 504 continues to move downward, and the extension frame 507 fixed outside the abutment block 506 also cannot move downward. Then, the moving plate 504 applies pressure to the piston rod 512, and the air inside the air tank 511 is injected into the airbag 510. The airbag 510 begins to expand. Under the combined compression of the twelve airbags 510 located at the edge of the product, the film will be squeezed to adhere to the product surface. Air overflows outward through the gap between two adjacent airbags 510. Finally, the moving plate 504 moves downward and connects with the fixing frame 516. Upon contact, the fixing frame 516 is pushed down along the four guide rods 514. The annular hot cutting blade 517, which is heated and mounted on the fixing frame 516, works with the top blade pad of the receiving frame 4 to complete the cutting of the film material. After the action is completed, the telescopic electric cylinder 502 begins to retract, driving the mounting plate 503 to move upward. The compressed springs 513 and 515 return to their length, and the piston rod 512 and the fixing frame 516 are pushed upward respectively to prepare for the next work. If it is necessary to change to other products, the position of the two mounting arms 509 inside the extension frame 507 can be adjusted to adapt to the exhaust work of products of different sizes. Furthermore, the extension frame 507 can be detached from the abutment block 506 and can be reused.
