Description

Technical Field

[0001] The present invention relates to the field of LED bulk chip mounter feeding, and more particularly, to an automatic feeding device for an LED bulk chip mounter. Background Art

[0002] LED bulk chip mounting refers to the process of automatically or semi-automatically mounting bulk (i.e., not pre-tape or sorted) LED components onto a printed circuit board (PCB) during production. This chip mounting method typically involves using a specially designed LED bulk chip mounter to improve production efficiency and mounting accuracy.

[0003] An automatic feeding device for LED bulk chip mounter, also known as an automatic feeding machine for LED bulk chip mounter, is a device specially designed to handle bulk LED components, automatically arrange them, and supply them to the chip mounter for mounting. This device is commonly used in the manufacturing processes of LED lighting, displays, and backlight modules, especially when dealing with a large number of bulk LEDs.

[0004] In the current feeding mechanism of LED bulk chip mounters, the mainstream design tends to use a single, fixed-position feeding die, which usually directly corresponds to the mechanical suction arm of the chip mounter to achieve a single-column suction mode. Although this design simplifies the equipment structure, it has significant shortcomings in terms of efficiency, flexibility, and production capacity. After the mechanical arm completes the single-column LED component suction in the single-die feeding mechanism, it must wait for the vibratory bowl to complete a new round of component arrangement before the next round of suction can be carried out, which limits the production rate. Moreover, when the single-die system encounters mechanical failures or maintenance requirements, the entire feeding process will be forced to pause until the problem is solved, resulting in an impact on the production schedule. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an automatic feeding device for an LED bulk chip mounter that can improve the production rate.

[0006] The technical solution is: an automatic feeding device for an LED bulk chip mounter, comprising a vibratory bowl, a connecting frame, a feeding rail, a blowing valve, and a feeding mechanism. The vibratory bowl is the main device for arranging LED chip bulk materials. A connecting frame is arranged on the right side of the vibratory bowl. A feeding rail is arranged at the discharging end of the vibratory bowl. A blowing valve is arranged above the connection between the feeding rail and the vibratory bowl. A feeding mechanism is arranged on the front side of the vibratory bowl, and there is a connection between the bottom of the connecting frame and a component included in the feeding mechanism.

[0007] Furthermore, the feeding mechanism includes: a connecting plate, a chassis, a bearing plate, a feeding die, a motor and a screw rod. A connecting plate is provided at the front end of the connecting frame and the feeding rail. The top of the connecting plate is at the same height as the top of the feeding rail. A chassis is provided at the bottom of the connecting plate. A chute is opened in the upper part of the bottom. A bearing plate is slidably arranged in the chute in the upper part of the chassis. The whole bearing plate is wider than the upper end face of the chassis. A number of symmetrically and closely attached feeding dies are arranged on the bearing plate. And the feeding end of one of the feeding dies faces the discharging end of the feeding rail, and there is a small distance interval between their feeding ends and discharging ends. A motor is arranged in the middle of the chassis. The output end of the motor faces right. A screw rod is arranged on the output end of the motor.

[0008] Furthermore, the die slots in the upper parts of a number of feeding dies are all of the same size as the track of the feeding rail, and the front end of the die slot in the upper part of the feeding die is closed.

[0009] Furthermore, a material blocking mechanism is also included. A material blocking mechanism is arranged between the feeding rail and the connecting plate, and one of the components included in the material blocking mechanism is in sliding contact with the feeding rail and the connecting plate; the material blocking mechanism includes: a slider, a connecting plate, a blocking block, a contact rod, a spring I, a mounting frame and a wedge block. A slider is slidably arranged in the left front side of the connecting plate. The upper end of the slider is in a protruding inclined shape. A connecting plate is arranged on the right front side of the slider. A blocking block is arranged on the rear side of the connecting plate. A contact rod is slidably arranged on the left side of the blocking block. A spring I is arranged between the rear part of the contact rod and the blocking block. The spring I is in a compressed state of force deformation. A number of symmetrically and closely attached mounting frames are arranged at the upper position of the rear side in the feeding dies. A number of symmetric wedge blocks are arranged on the rear side in the mounting frame. And the contact rod is in sliding contact with the inclined surface end of the wedge block.

[0010] Furthermore, the upper end of the blocking block is inclined. The blocking block is located below the interval between the feeding end of the feeding die and the discharging end of the feeding rail, and both ends of the blocking block are in sliding contact with their end faces.

[0011] Furthermore, a limiting slot is opened at the upper position of the rear part in the mounting frame. The front end of the limiting slot is located in the lower part of the mounting frame, and the front end of the limiting slot is inclined near the bottom position of the mounting frame. The front end of the contact rod is in sliding fit with the limiting slot. The end of the limiting slot is located in front of the leftmost wedge block.

[0012] Furthermore, a pushing mechanism is also included. A pushing mechanism is slidably arranged in the upper right part of the connecting plate; the pushing mechanism includes: a pushing member and a spring II. A pushing member is slidably arranged in the upper right part of the connecting plate. The front part of the pushing member is in an arc shape. The rear part of the pushing member extends downward, and the extended part of the rear part of the pushing member abuts against the inclined surface end of the upper part of the slider. A spring II is arranged between the pushing member and the upper right part of the connecting plate. The spring II is initially in a compressed state of force deformation.

[0013] Further, it further includes a limiting cover plate and a perspective plate. The limiting cover plate is snap-connected to the top of the feeding rail. The front part of the limiting cover plate is located above the loading die, and the front side of the bottom of the limiting cover plate covers the top of the loading die. A perspective plate is arranged in the middle of the limiting cover plate.

[0014] Further, it further includes a material pressing mechanism. The material pressing mechanism is arranged on the top of the limiting cover plate. The material pressing mechanism includes: an L-shaped support rod, a limiting member, a rotating member, a matching rod and a pressing rod. An L-shaped support rod is arranged on the right side of the stop block. A limiting member is arranged at one end of the L-shaped support rod. A rotating member is rotatably arranged inside the limiting member. Matching rods are rotatably arranged on both sides of the top of the limiting cover plate. The bottom of the matching rod at the rear is rotatably connected to the front end of the rotating member. A pressing rod is arranged between the two matching rods on both sides.

[0015] On the basis of overcoming the shortcomings of the prior art, the beneficial effects that the present invention can achieve are as follows:

[0016] 1. By driving the screw to rotate through the motor, the present invention realizes the cyclic positioning of the loading die, ensures the continuity of the production process, reduces the downtime, improves the throughput of the production line, and realizes the efficient loading of LED loose parts for chip mounter.

[0017] 2. Through this series of precise mechanical linkages and controls, the system of the present invention realizes the accurate control of picking up LED loose parts for chip mounter, avoids the problems of multi-material or material jamming, ensures that the mechanical suction arm can pick up a predetermined number of chips each time, and improves the production efficiency and product quality.

[0018] 3. By the contact between the arc part of the pushing member and the LED loose parts for chip mounter, the present invention ensures the stability of the chips during the movement of the die, and prevents the problems of dropping or excessive spacing of the loose parts for chip mounter due to the movement of the die.

[0019] 4. Through the limiting and adjustment of the LED loose parts by the limiting cover plate, the present invention ensures that the loose parts for chip mounter in each loading die are correctly arranged, improves the quality of chip arrangement, and provides material preparation for the subsequent chip mounting process.

[0020] 5. By the pressing of the pressing rod, the arranged LED loose parts for chip mounter are smoothed, reducing the possible chip mounting problems caused by unevenness. The measures for flat arrangement and stacking prevention of the chips improve the quality of the subsequent chip mounting process and reduce the chip mounting errors caused by uneven or stacked chips.

Detailed Implementation Modes

[0036] The following are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly.

[0037] Embodiment: An automatic feeding device for an LED bulk mounter, as Figures 1 - 9 and Figures 11 - 12 shown, includes a vibrating bowl 1, a connecting frame 11, a feeding rail 12, a blowing valve 13 and a feeding mechanism 2. The vibrating bowl 1 is the main device for arranging LED patch bulk materials. As the main device, the vibrating bowl 1 arranges the LED patch bulk materials neatly through vibration, preparing to enter the subsequent feeding and mounting processes. A connecting frame 11 is arranged on the right side of the vibrating bowl 1, a feeding rail 12 is arranged at the discharging end of the vibrating bowl 1, a blowing valve 13 is arranged above the connection between the feeding rail 12 and the vibrating bowl 1, and a feeding mechanism 2 is arranged on the front side of the vibrating bowl 1. And there is a connection between the bottom of the connecting frame 11 and a component included in the feeding mechanism 2. The connecting frame 11 and the feeding rail 12 ensure the smooth transition of the material from the vibrating bowl 1 to the feeding mechanism 2. The setting of the blowing valve 13 helps the precise guiding and acceleration of the material, ensuring that the LED patches can smoothly and quickly enter the feeding mechanism 2.

[0038] As Figures 1 - 9 and Figures 11 - 12As shown in the figure, the feeding mechanism 2 includes: an adapter plate 20, a chassis 21, a carrier plate 22, a feeding die 23, a motor 24 and a screw 241. An adapter plate 20 is provided at the front end of the connecting frame 11 and the feeding rail 12. The top of the adapter plate 20 is at the same height as the top of the feeding rail 12. The bottom of the adapter plate 20 is provided with a chassis 21. A chute is opened in the upper part of the bottom. A carrier plate 22 is slidably arranged in the chute in the upper part of the chassis 21. The overall width of the carrier plate 22 is wider than the upper end surface of the chassis 21. The design that the carrier plate 22 is wider than the upper end surface of the chassis 21 and the symmetrical and close arrangement of the feeding dies 23 make the space utilization of the entire feeding mechanism 2 more reasonable and the structure more compact, which is beneficial to saving production space and improving the layout efficiency of the production line. A number of symmetrically and closely arranged feeding dies 23 are provided on the carrier plate 22. The die slots in the upper parts of the several feeding dies 23 are all of the same size as the track of the feeding rail 12. The die slots in the upper parts of the feeding dies 23 being of the same size as the track of the feeding rail 12 ensures the precise alignment when the LED loose parts are pasted from the feeding rail 12 into the die slots, reducing the phenomenon of pasting misalignment or jamming caused by size mismatch. Moreover, the front ends of the die slots in the upper parts of the feeding dies 23 are closed, preventing the LED loose parts from slipping or moving during the loading process, ensuring the stable loading of the pasted parts in the die and avoiding material loss during the production process. Through the cooperation of the carrier plate 22 and the feeding die 23, the precise positioning of the LED loose parts during the feeding process is ensured. The feeding end of one feeding die 23 is directly opposite to the discharging end of the feeding rail 12, and there is a small distance interval between their feeding ends and discharging ends. A motor 24 is arranged in the middle of the chassis 21. The output end of the motor 24 faces right. A screw 241 is arranged on the output end of the motor 24. The rear end of the screw 241 is threadedly connected to the inner bottom of the carrier plate 22. The slidable arrangement of the carrier plate 22 in the chassis 21, combined with the rotation of the screw 241, realizes the cyclic movement of the feeding die 23. The start of the motor 24 and the rotation of the screw 241 can make the carrier plate 22 drive the feeding die 23 to move smoothly along the chute, thus realizing the continuous supply of materials and ensuring the continuity of the production process.

[0039] In use, first, place an appropriate amount of LED discrete patches in the designated area of the vibrating bowl 1, connect the blowing valve 13 to the compressed air source, and preheat the motor 24 in the feeding mechanism 2. Start the motor 24, and through the rotation of the screw 241, the carrier plate 22 moves within the chassis 21, driving the feeding die 23 to move synchronously until the first die aligns with the feeding rail 12, completing the preparatory step. Start the vibrating bowl 1, and the discrete patches move along the spiral track under the vibration, gradually aligning the direction, and finally feeding into the groove of the feeding rail 12. The blowing valve 13 receives a signal to open, and the compressed air blows the LED components to help them overcome the friction and accelerate the movement to the feeding die 23. When the first die completes the loading of a single row of LED discrete patches, the system controls the vibrating bowl 1 and the blowing valve 13 to pause. The motor 24 drives the screw 241 to rotate, positioning the next feeding die 23 at the outlet of the feeding rail 12, and repeating the feeding process until all the dies are loaded; after the final assembly, the mechanical suction arm sucks the LED discrete patches from the first feeding die 23. After all the discrete patches in the die are sucked, the motor 24 drives the screw 241 to rotate again, positioning the next die, and repeating the suction process until all the patch feeding is completed.

[0040] As Figures 6 - 7 and Figures 9 - 13As shown in the figure, there is also a material blocking mechanism 3. A material blocking mechanism 3 is arranged between the feeding rail 12 and the connecting plate 20, and a component included in the material blocking mechanism 3 is in sliding contact with the feeding rail 12 and the connecting plate 20; the material blocking mechanism 3 includes: a slider 30, a connecting plate 31, a blocking block 32, a contact rod 33, a spring I 34, a mounting frame 35 and a wedge block 36. A slider 30 is slidably arranged at the left front side inside the connecting plate 20. The upper end of the slider 30 is convex and inclined. A connecting plate 31 is arranged at the right front side of the slider 30. A blocking block 32 is arranged at the rear side of the connecting plate 31. The upper end of the blocking block 32 is inclined. The blocking block 32 is located below the interval between the feeding end of the loading die 23 and the discharging end of the feeding rail 12, ensuring that the LED loose parts can be accurately controlled and positioned when entering the loading die 23. Both ends of the blocking block 32 are in sliding contact with the end faces of the two, and can stably control the flow of materials, prevent overfeeding or material misalignment, and improve the accuracy of material supply. A contact rod 33 is slidably arranged on the left side of the blocking block 32. Through the cooperation of the blocking block 32 and the contact rod 33, the flow of the LED loose parts can be accurately controlled between the feeding rail 12 and the connecting plate 20, avoiding overfeeding or blockage of the materials, and improving the accuracy and controllability of the material flow. A spring I 34 is arranged between the rear part of the contact rod 33 and the blocking block 32. The spring I 34 is in a compressed state of being deformed by force. A mounting frame 35 is arranged at the upper position near the rear side inside several symmetric loading dies 23. A limiting groove 351 is opened at the upper position near the rear part inside the mounting frame 35, enabling the contact rod 33 to automatically adjust its position according to the guidance of the limiting groove 351 when the die moves. The front end of the limiting groove 351 is located at the lower part of the mounting frame 35, and the front end of the limiting groove 351 is inclined near the bottom position of the mounting frame 35. The front end of the contact rod 33 is slidably matched with the limiting groove 351. When the front end of the contact rod 33 slides into the limiting groove 351, it can move downward along the inclined front end. The end of the limiting groove 351 is located in front of the leftmost wedge block 36. Several symmetric wedge blocks 36 are arranged at the rear side inside the mounting frame 35, and the contact rod 33 is in sliding contact with the inclined surface end of the wedge block 36. Through the sliding contact between the contact rod 33 and the inclined surface end of the wedge block 36, and the compressed state of the spring I 34, when the loading die 23 moves, the contact rod 33 can release or block the blocking block 32 in a timely manner under the guidance of the wedge block 36, stabilizing the position of the materials in the die and preventing the LED loose parts from shaking or misaligning during the movement of the die.

[0041] To ensure that when the mechanical suction arm sucks the LED loose parts for patchwork, problems caused by excessive materials or extrusion in the feeding die 23 can be avoided. When the feeding die 23 moves with the carrier plate 22, the mounting frame 35 and the contact rod 33 and the stop block 32 inside it also move synchronously. The contact rod 33 is in inclined-plane contact with the wedge block 36 on the mounting frame 35. As the mounting frame 35 moves, the contact rod 33 pushes the stop block 32 upward until the contact rod 33 slides over the flat surface of the wedge block 36. At this time, the stop block 32 just blocks the small gap between the feeding rail 12 and the feeding die 23, preventing additional LED loose parts for patchwork from entering and ensuring the accurate number of patchwork in the die during suction. When the stop block 32 is in place, the motor 24 slows down and stops. Then the mechanical suction arm can accurately suck the LED loose parts for patchwork from the feeding die 23. After completing the material taking of one die, the motor 24 starts again, driving the screw rod 241 to rotate, positioning the next feeding die 23 at the material taking position, and the contact rod 33 contacts the next wedge block 36, repeating the above process. When the contact rod 33 contacts the last wedge block 36 and slides to the rightmost side, the front end of the contact rod 33 will enter the limit groove 351. At this time, the feeding die 23 has completed the material taking and needs to be refilled. The motor 24 drives the screw rod 241 to rotate, resetting the feeding die 23. The contact rod 33 returns along the limit groove 351 until the mounting frame 35 returns to the initial position. Under the guidance of the stop block 32 and the slider 30, the contact rod 33 automatically slides down and resets, preparing for the next round of material taking process.

[0042] As Figures 11 - 12 shown, it further includes a pushing mechanism 4. The pushing mechanism 4 is slidably arranged at the upper right part of the connecting plate 20. The pushing mechanism 4 includes: a pushing member 40 and a spring II 41. The pushing member 40 is slidably arranged at the upper right part of the connecting plate 20. The front part of the pushing member 40 is arc-shaped. After the front end of the contact rod 33 slides into the limit groove 351, it can move downward along the inclined front end. The rear part of the pushing member 40 extends downward, and the extended part of the rear part of the pushing member 40 abuts against the inclined-plane end of the upper part of the slider 30. A spring II 41 is arranged between the pushing member 40 and the upper right part of the connecting plate 20. The spring II 41 is initially in a compressed state of forced deformation. The forced deformation and recovery mechanism of the spring II 41 are linked with the slider 30, enabling the pushing member 40 to automatically reset and be ready for pushing again at the appropriate time. The forced deformation and recovery mechanism of the spring II 41 ensure the automatic reset of the pushing member 40 after pushing, avoiding potential safety hazards that may be caused by manual operation and improving the safety of the operation.

[0043] When loading LED loose parts onto the loading die 23 one by one, the loaded die 23 with single-row arrangement will be driven to move rightward by the carrier plate 22. At this time, the loading die 23 that first enters the moving sequence will be right in front of the rear of the pushing mechanism 4. At this moment, the LED loose parts in the die will contact the front arc part of the pushing member 40 of the pushing mechanism 4. Before this, the stop block 32 is in the state of sliding upward, and the connected slider 30 also slides synchronously. When the inclined surface at the upper end of the slider 30 disengages from the rear part of the pushing member 40, the originally compressed spring II 41 is no longer stressed. Then, the spring II 41 resets by its own elastic force, driving the pushing member 40 to slide forward. At this time, the arc part of the pushing member 40 will contact and apply force to the LED loose parts in the loading die 23, pushing them forward. This action ensures that when the loading die 23 moves, the LED loose parts in the die will not fall or have too wide a gap due to the movement. Especially for the LED loose parts near the edge at the front end of the loading die 23, they can be steadily pushed into the die, avoiding the instability of the loose parts during the movement, ensuring the accurate arrangement of the patches and the continuity of the loading.

[0044] As Figure 3 and Figures 8 - 9 shown, it also includes a limit cover plate 42 and a perspective plate 43. The limit cover plate 42 is clamped on the top of the feeding rail 12. The front part of the limit cover plate 42 is located above the loading die 23, and the front side of the bottom of the limit cover plate 42 covers the top of the loading die 23, which can prevent the LED loose parts from shifting or jumping during the loading process, ensuring that the materials enter the loading die 23 stably. A perspective plate 43 is arranged in the middle of the limit cover plate 42, enabling the operator or quality inspector to directly observe the material state in the feeding rail 12 and the loading die 23 through the limit cover plate 42, facilitating the real-time monitoring of the material arrangement.

[0045] When the vibrating bowl 1 feeds the LED loose parts into the feeding rail 12, the limit cover plate 42 at the top, in the event of possible abnormalities in the equipment, such as the stacking or inversion of LED loose parts, the inner edge of the limit cover plate 42 will restrict the positions of these abnormal loose parts, ensuring that they can only move along the predetermined direction and finally correctly enter the loading die 23. When the abnormal LED loose parts come into contact with the limit cover plate 42, their position deviations will be corrected, enabling them to smoothly enter the loading die 23 without causing chaos in the subsequent processes. To facilitate the quality inspector to monitor the arrangement of the LED loose parts, a perspective plate 43 is installed below the limit cover plate 42. Through the perspective plate 43, the quality inspector can clearly observe the arrangement state of the LED loose parts under the cover plate, ensuring that all loose parts are correctly arranged as required. During the loading process, each loading die 23 will pass under the limit cover plate 42 in sequence, thus ensuring that the loose part pasting in each die has been pre-limited and adjusted, guaranteeing the pasting arrangement quality. When it is necessary to adjust the position of the loading die 23, by controlling the motor 24 to drive the screw rod 241 to rotate, the position of the die can be precisely adjusted to ensure the smooth progress of the loading process.

[0046] As Figures 7 - 9 and Figures 11 - 14 shown, it further includes a pressing mechanism 5. A pressing mechanism 5 is arranged on the top of the limit cover plate 42. The pressing mechanism 5 includes: an L-shaped support rod 50, a limiting member 51, a rotating member 52, a mating rod 53 and a pressing rod 54. An L-shaped support rod 50 is arranged on the right side of the stop block 32. A limiting member 51 is arranged at one end of the L-shaped support rod 50. A rotating member 52 is rotatably arranged inside the limiting member 51. The cooperation between the limiting member 51 and the rotating member 52 can adjust the position of the pressing rod 54 according to the movement of the loading die 23, ensuring the precise matching of the pressing action and the material position, and improving the precision of material handling. Mating rods 53 are rotatably arranged on both sides of the top of the limit cover plate 42. The bottom of the mating rod 53 at the rear is rotatably connected to the front end of the rotating member 52. A pressing rod 54 is arranged between the two mating rods 53 on both sides. Through the linkage of the L-shaped support rod 50, the limiting member 51, the rotating member 52, the mating rod 53 and the pressing rod 54, a uniform pressure can be applied to the LED loose part pasting in the loading die 23, ensuring that the pasting is flat and closely arranged when entering the die, and avoiding subsequent processing problems caused by loose or stacked materials.

[0047] When the next loading die 23 passes under the limit cover plate 42, it will be driven by the carrier plate 22 through the threaded engagement with the screw rod 241 and move to the right until it aligns with the discharge end of the feeding plate. When the previous die moves to the right, the pushing mechanism 4 is activated. While pushing the material, the L-shaped support rod 50 is driven to move upward by the sliding abutting block. The upward movement of the L-shaped support rod 50 will drive the limiting member 51 at its top, thereby driving the rotating member 52 to rotate clockwise by 90 degrees. Since the two rotating members 52 are connected by the pressure rod 54, the rotation of one rotating member 52 will be linked to the other side, causing the pressure rod 54 to rotate synchronously to a position parallel to the LED loose parts patch. When the pressure rod 54 contacts the LED loose parts patch, through the applied pressure, the smoothing of the patch is achieved, ensuring its flat arrangement and avoiding stacking. Through this series of precise mechanical linkages, the LED loose parts patch is evenly smoothed in the loading die 23, ensuring that each patch can be arranged flatly, providing high-quality preparation for the subsequent mounting process, and at the same time avoiding mounting errors caused by stacking.

[0048] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.

A chute is formed in the upper part of the bottom. A bearing plate (22) is slidably arranged in the chute in the upper part of the chassis (21). The whole bearing plate (22) is wider than the upper end face of the chassis (21). A number of symmetrically and closely arranged feeding dies (23) are arranged on the bearing plate (22). The feeding end of one of the feeding dies (23) faces the discharging end of the feeding rail (12), and there is a small distance interval between their feeding ends and discharging ends. A motor (24) is arranged in the middle of the chassis (21). The output end of the motor (24) faces right. A screw rod (241) is arranged on the output end of the motor (24). The rear end of the screw rod (241) is in threaded connection with the inner bottom of the bearing plate (22). It further includes a material blocking mechanism (3). A material blocking mechanism (3) is arranged between the feeding rail (12) and the connecting plate (20), and a component included in the material blocking mechanism (3) is in sliding contact with the feeding rail (12) and the connecting plate (20). The material blocking mechanism (3) includes: a slider (30), a connecting plate (31), a blocking block (32), a contact rod (33), a spring I (34), a mounting frame (35) and a wedge block (36). A slider (30) is slidably arranged in the left front side of the connecting plate (20). The upper end of the slider (30) is convex and inclined. A connecting plate (31) is arranged on the right front side of the slider (30). A blocking block (32) is arranged on the rear side of the connecting plate (31). A contact rod (33) is slidably arranged on the left side of the blocking block (32). A spring I (34) is arranged between the rear part of the contact rod (33) and the blocking block (32). The spring I (34) is in a compressed state of force deformation. A mounting frame (35) is arranged at the upper position near the rear side in a number of symmetrically and closely arranged feeding dies (23). A number of symmetric wedge blocks (36) are arranged on the rear side in the mounting frame (35), and the contact rod (33) is in sliding contact with the inclined surface end of the wedge block (36). The die slots in the upper parts of a number of the feeding dies (23) are all of the same size as the track of the feeding rail (12), and the front ends of the die slots in the upper parts of the feeding dies (23) are closed. The upper end of the blocking block (32) is inclined. The blocking block (32) is located below the interval between the feeding end of the feeding die (23) and the discharging end of the feeding rail (12), and both ends of the blocking block (32) are in sliding contact with their end faces. A limiting groove (351) is formed at an upper position near the rear part inside the mounting frame (35). The front end of the limiting groove (351) is located at the lower part of the mounting frame (35), and the front end of the limiting groove (351) is inclined near the bottom position of the mounting frame (35). The front end of the contact rod (33) is in sliding fit with the limiting groove (351). The rear end of the limiting groove (351) is located in front of the leftmost wedge-shaped block (36). When the feeding die moves with the carrier plate, the mounting frame and the contact rod and the stop block inside it also move synchronously. The contact rod contacts the inclined surface of the wedge-shaped block on the mounting frame. As the mounting frame moves, the contact rod pushes the stop block upward until the contact rod slides over the flat surface of the wedge-shaped block. At this time, the stop block just blocks the small gap between the feeding rail and the feeding die, preventing additional loose material patches from entering and ensuring the accurate number of patches in the die during suction. When the stop block is in place, the motor slows down and stops. Then the mechanical suction arm can accurately suck the LED loose material patches from the feeding die. After completing the material taking of one die, the motor starts again, drives the screw to rotate, positions the next feeding die to the material taking position, and the contact rod contacts the next wedge-shaped block, repeating the above process. When the contact rod contacts the last wedge-shaped block and slides to the rightmost side, the front end of the contact rod will enter the limiting groove. At this time, the feeding die has completed the material taking and needs to be re-fed. The motor drives the screw to rotate to reset the feeding die, and the contact rod returns along the original path of the limiting groove until the mounting frame returns to the initial position. Under the guidance of the stop block and the slider, the contact rod automatically slides down and resets, preparing for the next round of material taking process.
