Description

Technical Field

[0001] This invention relates to the field of surface mount resistor packaging technology, and specifically to a surface mount resistor packaging device and packaging method. Background Technology

[0002] Surface mount resistors (SMRs) are surface-mount components widely used in modern electronic circuits. They are characterized by their small size, light weight, high mounting density, and high efficiency in automated production, making them a key component for miniaturization, weight reduction, and high performance in electronic devices. The packaging process for SMRs requires various devices and equipment, covering the entire process from material preparation to finished product packaging. Specifically, this includes: substrate preparation, printing, sintering, laser trimming, end-face treatment, testing and sorting, and tape and reel packaging. Through these devices and processes, SMRs can achieve high precision, miniaturization, and mass production, meeting the electronics industry's demand for miniaturized, high-performance components.

[0003] In existing technologies, the packaging process of surface mount resistors typically requires the use of laser cutting equipment to perform laser resistance adjustment on the sintered resistors, especially in the resistance value adjustment and fine-tuning stages. However, when using laser cutting equipment to cut resistors, no mechanism is set up to correct the position of the resistors. The resistors to be processed are simply transported to the bottom of the laser cutting equipment by a conveyor belt. Because the conveyor belt vibrates during operation, the position of the resistors will deviate after being vibrated, which is not conducive to the subsequent accurate laser cutting process. This results in a lot of waste material generated during the packaging process, increasing the production cost for enterprises. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a packaging device and method for surface mount resistors.

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

[0006] A surface mount resistor packaging device includes a device body. A conveyor belt is rotatably mounted inside the device body. Two placement boxes are mounted on the outer wall of the conveyor belt. The interior of each placement box is divided into multiple placement slots by multiple movable plates. Two drive plates for moving and adjusting the multiple movable plates are slidably mounted in the center of each placement box. The top of each placement box is provided with a correction mechanism for correcting the position of the two ends of the resistors placed in the multiple placement slots. The top of the device body is provided with a detection mechanism for automatically detecting the resistors and a processing mechanism for automatically processing the resistors.

[0007] Optionally, the detection mechanism includes two first slide grooves opened on the top of the device body, each of the two first slide grooves having a first slider installed inside, and the top of the two first sliders having a common movable frame installed.

[0008] Optionally, the bottom of the mobile frame is provided with a second sliding groove, and a second slider is installed inside the second sliding groove. The bottom end of the second slider is connected to a mounting plate through an electric telescopic rod. Multiple industrial cameras and vacuum suction cups are respectively installed on the bottom of the mounting plate.

[0009] Optionally, the processing mechanism includes two telescopic cylinders installed on the top of the device body. The telescopic ends of the two telescopic cylinders are jointly equipped with a top plate. A third sliding groove is opened at the bottom of the top plate. A third slider is installed inside the third sliding groove. A horizontal plate is installed at the bottom of the third slider. A fourth sliding groove is opened at the bottom of the horizontal plate. A fourth slider is installed inside the fourth sliding groove. A laser head is installed at the bottom of the fourth slider.

[0010] Optionally, a first double-ended screw is rotatably installed on both outer walls of the placement box, and both ends of the two drive plates are threadedly connected to the first double-ended screws that are close to them. A first electromagnet is installed on the outer wall of the two drive plates that are far apart from each other, and the two first electromagnets are magnetically fixed to the movable plates that are close to them.

[0011] Optionally, two mounting seats are provided between the multiple movable plates, and two connecting rods are rotatably installed on the outer wall of the two movable plates on the side where they are close to each other. The ends of the two connecting rods away from the movable plates are rotatably connected to the mounting seats that are close to them.

[0012] Optionally, the correction mechanism includes two grooves opened on the top of the placement box, with a second double-ended screw rotatably installed inside each of the two grooves, and a moving block threaded onto the outer wall of each of the two second double-ended screws. A rotating plate is rotatably installed between the two cooperating moving blocks.

[0013] Optionally, the bottom of each of the two rotating plates is slidably mounted with the same number of sliding plates as the placement slots, and a housing is installed on the outer wall of the two rotating plates on the side away from each other. A winding roller is rotatably mounted inside each of the two housings.

[0014] Optionally, both of the outer walls of the two take-up rollers are wound with shielding cloth, and a connecting plate is installed at the end of each shielding cloth away from the take-up roller. A second electromagnet is preset inside each of the two connecting plates.

[0015] Optionally, a method for packaging a surface mount resistor includes the packaging device described above, and the packaging method further includes the following steps:

[0016] Step 1: Place the resistors to be processed inside the placement box, and use the detection mechanism to automatically identify and detect multiple resistors;

[0017] Step 2: After the multiple resistors inside the placement box are tested, control the two first double-headed screws to drive the two drive plates to move in opposite directions. Push the three moving plates on the opposite side of the two drive plates so that the multiple moving plates move and adjust together inside the placement box. In turn, push the resistors placed inside the placement box synchronously to ensure that the multiple resistors are all in a horizontal position inside the multiple placement slots.

[0018] Step 3: After multiple moving plates push and correct both sides of multiple resistors inside the placement box, control the two second double-headed screws to drive the two moving blocks and rotating plates to move and adjust in the same direction, and drive multiple sliding plates together to push and correct the other sides of the resistors inside the corresponding placement slots, ensuring that the multiple resistors are in the center position inside the multiple placement slots.

[0019] Step 4: After correcting the positions of multiple resistors inside the placement box through Steps 2 and 3 above, control the conveyor belt to rotate counterclockwise to move the placement box directly below the processing mechanism. The processing mechanism then performs laser cutting on the multiple resistors placed inside the placement box to make the resistors meet the design requirements.

[0020] Step 5: After the resistors inside the placement box are laser-cut by the processing mechanism, the conveyor belt continues to rotate counterclockwise until the placement box moves to the left end near the main body of the device. The unloading robot at the left end of the main body of the device automatically removes the cut resistors. As the conveyor belt continues to rotate counterclockwise, the placement box at the top of the conveyor belt rotates to the bottom, and the placement box at the bottom of the conveyor belt rotates to the top, so that the loading robot can place the resistors to be processed later inside for related testing and processing.

[0021] The beneficial effects of this invention are:

[0022] 1. In this invention, through the cooperation between the correction mechanism set on the top of the placement box and multiple moving plates, the positions of multiple resistors placed inside the placement box can be automatically pushed and corrected, ensuring that multiple resistors are located in the center position inside multiple placement slots, improving the accuracy of subsequent processing mechanisms in resistor processing, reducing waste generated during resistor packaging processing, and thus reducing the production cost of enterprises.

[0023] 2. In this invention, during the rotation of the bottom of the placement box at the top of the conveyor belt, the resistor waste material remaining inside the placement box can be automatically discharged downwards from the inside of the placement box, achieving the effect of automatically cleaning and removing the resistor waste material, and avoiding the problem of resistor waste material remaining inside the placement box and hindering the subsequent processing of resistors.

[0024] 3. In this invention, two drive plates push multiple moving plates, so that the resistor waste located inside the placement box can be squeezed and crushed. After the resistor waste is squeezed and crushed, it is easier to recycle the relevant materials in the future.

[0025] 4. In this invention, since the two shielding cloths are located at the top of the placement box during the crushing and squeezing of the resistor waste inside the placement box, and block the opening at the top of the placement box, the phenomenon of resistor waste splashing outwards during the crushing and squeezing process by multiple moving plates can be avoided. This can improve the safety of crushing and squeezing resistor waste, and also avoid the problem of the crushed resistor waste splashing outwards and needing to be collected again by staff later.

[0040] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Reference Figures 1-12 A surface mount resistor packaging device includes a device body 1. A conveyor belt 2 is rotatably mounted inside the device body 1. Two placement boxes 11 are mounted on the outer wall of the conveyor belt 2. The interior of each placement box 11 is divided into multiple placement slots by multiple movable plates 12. Two drive plates 21 for driving the multiple movable plates 12 to move and adjust are slidably mounted in the center of each placement box 11. The top of each placement box 11 is provided with a correction mechanism for correcting the position of the two ends of the resistors placed in the multiple placement slots. The top of the device body 1 is provided with a detection mechanism for automatically detecting the resistors and a processing mechanism for automatically processing the resistors.

[0042] As a technical optimization of the present invention, the detection mechanism includes two first slide grooves 6 opened on the top of the device body 1. A first slider 13 is installed inside each of the two first slide grooves 6, and a movable frame 3 is installed at the top of both first sliders 13. A first linear motor is pre-installed inside each of the two first slide grooves 6. The two first linear motors drive the two first sliders 13 to move back and forth inside the corresponding first slide grooves 6, thereby causing the movable frame 3 to move and adjust on the top of the device body 1.

[0043] As a technical optimization of the present invention, the bottom of the movable frame 3 is provided with a second sliding groove 14, and a second slider 15 is installed inside the second sliding groove 14. The bottom end of the second slider 15 is connected to a mounting plate 5 through an electric telescopic rod 4. Multiple industrial cameras 16 and vacuum suction cups 17 are respectively installed on the bottom of the mounting plate 5. A second linear motor is preset inside the second sliding groove 14. The second linear motor can drive the second slider 15 to move back and forth inside the second sliding groove 14, thereby driving the electric telescopic rod 4 and the mounting plate 5 to move and adjust synchronously. During the extension and retraction process, the telescopic end of the electric telescopic rod 4 can drive the mounting plate 5 and the multiple industrial cameras 16 and vacuum suction cups 17 installed at its bottom to move and adjust synchronously. The multiple industrial cameras 16 are all industrial cameras of the prior art model BIP2-1300c-dn. The multiple vacuum suction cups 17 are all connected to externally preset vacuum equipment through flexible hoses, so that the multiple vacuum suction cups 17 have suction force when in use.

[0044] As a technical optimization of the present invention, the processing mechanism includes two telescopic cylinders 7 installed on the top of the device body 1. A top plate 8 is installed on the telescopic ends of the two telescopic cylinders 7. A third slide groove 18 is formed at the bottom of the top plate 8. A third slider is installed inside the third slide groove 18. A horizontal plate 9 is installed at the bottom of the third slider. A fourth slide groove 19 is formed at the bottom of the horizontal plate 9. A fourth slider is installed inside the fourth slide groove 19. A laser head 10 is installed at the bottom of the fourth slider. A third linear motor is preset inside the third slide groove 18. The third linear motor can drive the third slider to move back and forth inside the third slide groove 18, thereby driving the horizontal plate 9 to move and adjust at the bottom of the top plate 8. A fourth linear motor is preset inside the fourth slide groove 19. The fourth linear motor can drive the fourth slider to move back and forth inside the fourth slide groove 19, thereby driving the laser head 10 to move and adjust at the bottom of the horizontal plate 9.

[0045] As a technical optimization of the present invention, first double-ended screws 20 are rotatably installed on both outer walls of the placement box 11. Both ends of the two drive plates 21 are threadedly connected to the adjacent first double-ended screws 20. First electromagnets 28 are installed on the outer walls of the two drive plates 21 on the opposite side. The two first electromagnets 28 are magnetically fixed to the adjacent movable plates 12. Two first drive motors are pre-installed on one outer wall of the placement box 11. The output ends of the two first drive motors are connected to one end of the adjacent first double-ended screws 20, thereby driving the two first double-ended screws 20 to rotate on both sides of the placement box 11, which in turn drives the two drive plates 21 to move and adjust within the placement box 11 in a direction closer or further apart. When the two first electromagnets 28 are energized and generate magnetism, they can be magnetically fixed to the adjacent movable plates 12.

[0046] As a technical optimization of the present invention, two mounting seats 26 are provided between each of the multiple movable plates 12. Two connecting rods 27 are rotatably installed on the outer wall of the side of the multiple movable plates 12 that are close to each other. The ends of the two connecting rods 27 away from the movable plates 12 are rotatably connected to the mounting seats 26 that are close to each other. After the two first electromagnets 28 are magnetically attracted and fixed to the movable plates 12 that are close to each other, the multiple movable plates 12 can be moved and adjusted synchronously inside the placement box 11 as the two drive plates 21 move. That is, the two drive plates 21 can push and pull the three movable plates 12 on the side that are far from each other inside the placement box 11. During the movement of the three movable plates 12, the cooperation of the two mounting seats 26 and the connecting rods 27 on the side that are close to each other can realize that the three movable plates 12 move and adjust together in one direction inside the placement box 11.

[0047] As a technical optimization of the present invention, the correction mechanism includes two grooves 22 opened on the top of the placement box 11. A second double-ended screw 29 is rotatably installed inside each of the two grooves 22. Moving blocks 23 are threaded onto the outer walls of each of the two second double-ended screws 29. A rotating plate 24 is rotatably installed between the two cooperating moving blocks 23. Two second drive motors are preset on one side of the outer wall of the placement box 11. The output ends of the two second drive motors are respectively connected to one end of the two second double-ended screws 29, thereby driving the two second double-ended screws 29 to rotate inside the corresponding grooves 22, which in turn drives the two moving blocks 23 to move closer or further apart, thereby driving the two rotating plates 24 to move together on the top of the placement box 11 in a closer or further apart direction for adjustment. A third drive motor is preset inside one of the two moving blocks 23. The output ends of the two third drive motors are respectively connected to the rotating parts of one end of the two rotating plates 24, thereby driving the two rotating plates 24 to rotate and adjust between the corresponding moving blocks 23.

[0048] As a technical optimization of the present invention, the bottom of each of the two rotating plates 24 is slidably equipped with sliding plates 30, the same number as the placement slots. A housing 25 is installed on the outer wall of each of the two rotating plates 24 on opposite sides. A take-up roller 31 is rotatably installed inside each of the two housings 25. A fourth drive motor is pre-installed on one side of the outer wall of each of the two housings 25. The output ends of the two fourth drive motors are respectively connected to one end of the corresponding take-up roller 31, thereby enabling the two take-up rollers 31 to rotate and adjust within the corresponding housings 25.

[0049] As a technical optimization of the present invention, both take-up rollers 31 have a shielding cloth 32 wound around their outer walls. A connecting plate 33 is installed at the end of each shielding cloth 32 away from the take-up rollers 31, and a second electromagnet is preset inside each of the two connecting plates 33. During the rotation of the two take-up rollers 31, the shielding cloth 32 wound around their outer walls can be unfolded or wound up.

[0050] As a technical optimization of the present invention, a method for packaging a surface mount resistor includes the packaging device described above, and the packaging method further includes the following steps:

[0051] Step 1: Place the resistors to be processed inside the placement box 11, and use the detection mechanism to automatically identify and detect multiple resistors;

[0052] Step 2: After the multiple resistors inside the placement box 11 are tested, the two first double-headed screws 20 are controlled to drive the two drive plates 21 to move in opposite directions. The three moving plates 12 on the opposite side of the two drive plates 21 are pushed, so that the multiple moving plates 12 move and adjust together inside the placement box 11. The resistors placed inside the placement box 11 are pushed synchronously to ensure that the multiple resistors are all in a horizontal position inside the multiple placement slots.

[0053] Step 3: After multiple moving plates 12 push and correct both sides of multiple resistors inside the placement box 11, control the two second double-headed screws 29 to drive the two moving blocks 23 and rotating plates 24 to move and adjust in the same direction, and drive multiple sliding plates 30 together to push and correct the other sides of the resistors inside the corresponding placement slots, ensuring that the multiple resistors are in the center position inside the multiple placement slots.

[0054] Step 4: After the positions of the multiple resistors inside the placement box 11 are corrected through Step 2 and Step 3 above, the conveyor belt 2 is controlled to rotate counterclockwise to move the placement box 11 directly below the processing mechanism. The processing mechanism is used to perform laser cutting processing on the multiple resistors placed inside the placement box 11 so that the resistors meet the design requirements.

[0055] Step 5: After the resistors inside the placement box 11 are laser-cut by the processing mechanism, the conveyor belt 2 continues to rotate counterclockwise until the placement box 11 moves to the left end near the device body 1. The unloading robot at the left end of the device body 1 automatically removes the cut resistors. As the conveyor belt 2 continues to rotate counterclockwise, the placement box 11 at the top of the conveyor belt 2 rotates to the bottom, and the placement box 11 at the bottom of the conveyor belt 2 rotates to the top, so that the loading robot continues to place the resistors to be processed inside for related testing and processing.

[0056] In this embodiment, the width of the strip resistor is smaller than the distance between two adjacent moving plates 12, that is, smaller than the width of the placement slot, but larger than the width of the sliding plate 30. This ensures that when multiple moving plates 12 push the sides of the resistor, after the sides of the resistor come into contact with the moving plates 12, the sliding plate 30 will not disengage from the moving plates 12. The sliding plate 30 will remain between two adjacent moving plates 12, but will not obstruct the movement of the moving plates 12.

[0057] In this invention, when the user uses the device, such as Figure 1 As shown, multiple strip-shaped resistors to be processed are sequentially placed inside the placement box 11 using a pre-set loading robot, ensuring that each resistor is placed in a different placement slot. At this time, the telescopic end of the electric telescopic rod 4 extends downwards, moving the mounting plate 5 and its multiple industrial cameras 16 downwards to a position close to the placement box 11. The second slider 15 moves back and forth inside the second slide groove 14, consequently causing the mounting plate 5 and the multiple industrial cameras 16 to move back and forth on the top of the placement box 11 for adjustment. This allows the multiple industrial cameras 16 to observe the resistors placed in the multiple placement slots. Automatic identification and detection: If a quality problem is detected in the resistor to be processed, the telescopic end of the electric telescopic rod 4 can be controlled to continue moving downward, causing multiple vacuum suction cups 17 to come into contact with the top of the resistor and adhere to it. As the telescopic end of the electric telescopic rod 4 retracts back to its original position, the resistor can be moved upward from the inside of the placement box 11. The resistor is then transferred from the bottom of the multiple vacuum suction cups 17 by a preset transfer robot. This achieves the effect of pre-detecting the resistor to be processed and automatically rejecting resistors with unqualified quality, thus preventing the processing mechanism from continuing to process resistors with unqualified quality.

[0058] After the multiple resistors inside the placement box 11 are tested, the two first double-headed screws 20 can be controlled to rotate together, driving the two drive plates 21 to move in opposite directions. This pushes the three moving plates 12 on the opposite side of the two drive plates 21, causing the three moving plates 12 to move together to both sides inside the placement box 11. During the process of the multiple moving plates 12 moving and adjusting inside the placement box 11, the resistors placed inside the placement box 11 can be pushed synchronously to ensure that the multiple resistors are all in a horizontal position inside the multiple placement slots, which facilitates the subsequent processing mechanism to accurately process the resistors.

[0059] Meanwhile, after multiple movable plates 12 push and correct both sides of multiple resistors inside the placement box 11, two second double-headed screws 29 can be controlled to rotate together inside the corresponding grooves 22. This will cause the two movable blocks 23 and rotating plates 24 to move and adjust towards each other. This will cause multiple sliding plates 30 at the bottom of the two rotating plates 24 to push and correct the other sides of the resistors inside the corresponding placement slots, ensuring that the multiple resistors are located in the center position inside the multiple placement slots, and further improving the accuracy of the subsequent processing mechanism in processing the resistors.

[0060] After the positions of multiple resistors inside the placement box 11 are corrected using multiple moving plates 12 and two rotating plates 24 of the correction mechanism, the two drive plates 21 maintain the adjusted state described above, so that they continue to push and limit the multiple moving plates 12. This allows the multiple moving plates 12 to maintain the pushing and limiting of the multiple resistors on both sides, and controls the correction mechanism to also maintain the pushing and limiting of the other two ends of the multiple resistors. This ensures that the multiple resistors to be cut remain stable inside the placement box 11. By controlling the conveyor belt 2 to rotate counterclockwise inside the device body 1, the placement box 11 can be moved to the bottom of the processing mechanism. With the downward retraction of the extension ends of the two telescopic cylinders 7, the laser head 10 is driven to perform related laser cutting processing on the multiple resistors placed and fixed inside the placement box 11. The excess parts at both ends or edges of the strip resistors are quickly cut and removed, or the strip resistors are laser-trimmed to directly cut the strip resistors into multiple block resistors of the same size, so as to achieve precise trimming of the resistance value and achieve the design requirements.

[0061] After the resistors inside the placement box 11 are laser-cut by the laser head 10 of the processing mechanism, the conveyor belt 2 continues to rotate counterclockwise until the placement box 11 moves to the left end near the device body 1. Then, the two drive plates 21 are moved and reset, causing multiple moving plates 12 to release the pushing limit on both sides of multiple resistors. At the same time, the correction mechanism can be moved and reset at the top of the placement box 11, causing multiple sliding plates 30 to also release the pushing limit on the other sides of multiple resistors. The cutting robot at the left end of the device body 1 automatically takes out the cut resistors. After the resistors inside the placement box 11 are taken out, as the conveyor belt 2 continues to rotate counterclockwise, the placement box 11 at the top of the conveyor belt 2 rotates to the bottom, and the placement box 11 at the bottom of the conveyor belt 2 rotates to the top. The other placement box 11 at the top of the conveyor belt 2 is now located at the right end of the device body 1, so that the loading robot can continue to place the resistors to be processed inside for related testing and processing, achieving the effect of continuous processing of a large number of resistors.

[0062] During the rotation of the bottom of the placement box 11 located at the top of the conveyor belt 2, the resistor waste material stored inside the placement box 11 can be automatically discharged downward from the inside of the placement box 11, achieving the effect of automatically cleaning and removing the resistor waste material, and avoiding the problem of resistor waste material remaining inside the placement box 11, which would hinder the subsequent processing of resistors.

[0063] Meanwhile, since surface mount resistors are typically composed of a ceramic substrate, metal electrodes, and resistive material, after laser cutting and fine-tuning, the waste still contains a certain proportion of metal materials and other recyclable components. These metal materials have high recycling value and can be extracted and reused through professional recycling processes. To facilitate the subsequent recycling of some resistor waste, after the processed resistors are removed from the placement box 11 using a robotic arm, the two rotating plates 24 are controlled to rotate and adjust between the corresponding two moving blocks 23, driving the two housings 25 to rotate to a close position. The two second double-headed screws 29 are then controlled to rotate, driving the two rotating plates 24 to move towards each other until the connecting plates 33 on one side of the outer walls of the two housings 25 move to abutting position. Then, the second electromagnets inside the two connecting plates 33 are energized to generate magnetism, causing them to magnetically attract and fix each other. After magnetic attraction, the two take-up rollers 31 are controlled to rotate inside the corresponding housing 25, so that the two shielding cloths 32 rotate and unfold together inside the housing 25. As the two rotating plates 24 move away from each other and reset, the two shielding cloths 32 are horizontally unfolded on the top of the placement box 11, thus covering the top of the placement box 11. As the two rotating plates 24 are rotated and adjusted as described above, the multiple sliding plates 30 at their bottoms rotate together to the top of the rotating plates 24, so that there is no obstruction between the multiple moving plates 12. As the two drive plates 21 continue to move away from each other, the multiple moving plates 12 are pushed further. As the multiple moving plates 12 move towards each other, they can automatically crush the resistor waste material left in the placement slot. After crushing the resistor waste material, it is easier to recycle the relevant materials in the future.

[0064] Furthermore, since the two shielding cloths 32 are located on top of the placement box 11 and cover the opening at the top of the placement box 11, the phenomenon of resistor waste splashing outwards during the crushing process by multiple moving plates 12 can be avoided. This can improve the safety of crushing resistor waste and also prevent the crushed resistor waste from splashing outwards, which would require staff to collect it again later.

[0065] After the two shielding cloths 32 seal the top opening of the placement box 11, the resistance waste can be discharged downwards and piled up on top of the two shielding cloths 32 after the placement box 11 rotates downwards to the bottom of the device body 1. The conveyor belt 2 drives the placement box 11 to move to the designated position at the bottom of the device body 1, and then controls the second electromagnet inside the two connecting plates 33 to be de-energized, so that the resistance waste piled up on top of the two shielding cloths 32 can be accurately discharged downwards into the preset collection container, avoiding the problem of resistance waste not being accurately collected.

[0066] Meanwhile, if the resistors inside the placement box 11 are processed into multiple blocks of the same size and no related resistor waste is generated, the unloading robot pre-installed on the left side of the device body 1 is not convenient for automatically removing and unloading small block resistors. In this case, the above steps can be repeated to drive the two shielding cloths 32 to unfold at the top of the placement box 11. After the placement box 11 rotates to the bottom of the device body 1, the resistors processed into multiple blocks inside can be automatically discharged to the top of the two shielding cloths 32 for temporary storage. Then, the multiple block resistors can be collected in a concentrated manner, which can facilitate the unloading and collection of resistors processed into multiple blocks.

7. A method for packaging a surface mount resistor, characterized in that, It employs the packaging apparatus of claim 6 to perform the process, and the packaging method further includes the following steps: Step 1: Place the resistors to be processed inside the placement box (11), and use the detection mechanism to automatically identify and detect multiple resistors; Step 2: After the multiple resistors inside the placement box (11) are detected, the two first double-headed screws (20) are controlled to drive the two drive plates (21) to move in opposite directions. The three moving plates (12) on the opposite side of the two drive plates (21) are pushed so that the multiple moving plates (12) move and adjust together inside the placement box (11). The resistors placed inside the placement box (11) are pushed synchronously to ensure that the multiple resistors are all in a horizontal position inside the multiple placement slots. Step 3: After the multiple moving plates (12) push and correct the two sides of the multiple resistors inside the placement box (11), control the two second double-headed screws (29) to drive the two moving blocks (23) and the rotating plate (24) to move and adjust in the same direction, and drive the multiple sliding plates (30) together to push and correct the other two sides of the resistors inside the corresponding placement slots, so as to ensure that the multiple resistors are located in the center position inside the multiple placement slots. Step 4: After the positions of multiple resistors inside the placement box (11) are corrected through Step 2 and Step 3 above, the conveyor belt (2) is controlled to rotate counterclockwise to move the placement box (11) to the bottom of the processing mechanism. The processing mechanism is used to perform related laser cutting processing on the multiple resistors placed inside the placement box (11) so that the resistors meet the design requirements. Step 5: After the resistor inside the placement box (11) is laser-cut by the processing mechanism, the conveyor belt (2) continues to rotate counterclockwise until the placement box (11) moves to the left end near the device body (1). The unloading robot on the left end of the device body (1) automatically takes out the cut resistor. As the conveyor belt (2) continues to rotate counterclockwise, the placement box (11) at the top of the conveyor belt (2) rotates to the bottom. The placement box (11) at the bottom of the conveyor belt (2) rotates to the top, so that the loading robot continues to place the resistor to be processed inside for related testing and processing.
