[0002] SMT (Surface Mount Technology) is a core technology in modern electronics manufacturing and is widely used in consumer electronics, communication equipment, automotive electronics and other fields. The core equipment of SMT technology is the SMT placement machine, which can automatically pick up components and place them accurately on the PCB through an electronic eye recognition device.

[0003] In actual production, when the tape in the pick-and-place machine is about to run out, it is necessary to connect the head of the new tape in the storage cartridge with the tail of the old tape in the pick-and-place machine through the tape receiving machine. This requires the new tape in the storage cartridge to be transported to the receiving platform of the tape receiving machine. In order to improve production efficiency, multiple storage cartridges with new tapes are usually arranged on a pallet, and then the pallet is manually moved to the tape receiving machine for the tape receiving machine to pick up the material. Obviously, the manual feeding method has the problems of low work efficiency and high labor intensity. Utility Model Content

[0004] The purpose of this utility model is to provide a material tray feeding mechanism and a material belt receiving machine to solve the problem of low work efficiency in conventional manual feeding in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

The conveying assembly is provided with a notch for avoiding the bearing member. The drive end of the second drive assembly is connected to the bearing member. The second drive assembly is configured to drive the bearing member to lift and lower.

[0010] The second drive component drives the carrier to rise to a preset height so that the carrier is in a high position, thereby pushing the pallet of the loading station away from the conveying surface of the conveying component. The first drive component drives the carrier in the high position to move forward one step at a time along the first direction so as to move the first material strip clips on the pallet to the picking station in sequence. The step is the thickness of a single first material strip clip.

[0011] Furthermore, the conveying assembly has a material unloading station on its conveying path, and the conveying assembly is also configured to convey the pallet to the material unloading station along the first direction.

When the track wheel abuts against the low position, the carrier is in a low position, so as to cooperate with the carrier to place the pallet on the conveying surface of the conveying assembly.

[0015] Furthermore, each of the track plates has two track slots, which are spaced apart along a first direction. There are two sets of track wheels, with the two track slots on the two track plates at the same position corresponding to one set of track wheels.

[0033] Please see Figures 1 to 4 As shown, in this embodiment, a tray loading mechanism includes a conveying component 10, a first driving component 20, and a carrying component 30, wherein: a loading station is provided on the conveying path of the conveying component 10, and the conveying component 10 is at least configured to receive a tray 40 and load the received tray 40 along a first direction ( Figure 1 The conveyor assembly 10 is conveyed to the loading station in the X direction. The pallet 40 is configured to carry at least a plurality of first material strip clips 41 arranged along the first direction. Each first material strip clip 41 is configured to carry a full material tray 42. The drive end of the first drive assembly 20 is connected to the carrying assembly 30, and the first drive assembly 20 is configured to drive the carrying assembly 30 to move along the first direction. The carrying assembly 30 is located below the loading station and includes a second drive assembly 31 and a carrying member 32. The conveyor assembly 10 has a notch for avoiding the carrying member 32. The drive end of the second drive assembly 31 is connected to the carrier 32. The second drive assembly 31 is configured to drive the carrier 32 to rise and fall. The second drive assembly 31 drives the carrier 32 to rise to a preset height so that the carrier 32 is in a high position, thereby pushing the pallet 40 of the loading station away from the conveying surface of the conveying assembly 10. The first drive assembly 20 drives the carrier 32 in the high position to move forward one step at a time along the first direction so as to move the first material strip clip 41 on the pallet 40 to the picking station in sequence. The step distance is the thickness of a single first material strip clip 41.

[0034] Specifically, the first drive component 20 may be a cylinder, a motor, or a drive module with linear stroke.

[0035] As can be seen, through the cooperation of the conveying component 10, the first driving component 20 and the carrying component 30, the conveying component 10 receives the pallet 40 and conveys the received pallet 40 to the loading station along the first direction. The pallet 40 carries a number of first material strip clips 41. The second driving component 31 drives the carrying component 32 to rise to a preset height, so that the carrying component 32 is in a high position, pushing the pallet 40 at the loading station away from the conveying surface of the conveying component 10. The first driving component 20 drives the carrying component 32, which is in a high position, to move forward one step at a time along the first direction, moving the first material strip clips 41 on the pallet 40 to the picking station in sequence. No manual loading is required, which greatly improves work efficiency.

[0036] It should be noted that: the external handling mechanism takes away the first material strip clip 41 of the full material tray 42 located at the material picking station and places it at the receiving platform before proceeding with subsequent operations. After the material strip on the full material tray 42 is used up, the external handling mechanism then moves the first material strip clip 41 of the empty material tray 42 to the material picking station.

[0037] In one embodiment, a material unloading station is provided on the conveying path of the conveying component 10. The conveying component 10 is also configured to convey the pallet 40 to the material unloading station along the first direction. The pallet 40 is also configured to carry a plurality of first material strip clips 41 arranged along the first direction. The first material strip clips 41 are configured to carry empty material trays 42.

[0038] As can be seen, by setting up a feeding station, the conveying component 10 conveys the empty material tray 42 to the feeding station along the first direction, thereby realizing the automatic feeding of the empty material tray 42.

[0039] In one embodiment, the second drive assembly 31 includes a support 310, a drive unit 311, a lateral movement member 312, a track plate assembly, and at least one set of track wheels, wherein: the support 310 is connected to the drive end of the first drive assembly 20; the lateral movement member 312 is reciprocally mounted on the support 310 along a first direction; the track plate assembly includes two track plates 313, which are mounted on the lateral movement member 312 along a second direction (…). Figure 1At both ends of the Y-direction, at least one track groove 314 is provided at the corresponding position of each track plate 313. At least one set of track wheels is installed at the bottom of the support member 32. Each set of track grooves 314 corresponds to one set of track wheels. Each set of track wheels includes two track wheels 315, and each track wheel 315 is inserted into the corresponding track groove 314. The track groove 314 includes a high part 3141, a low part 3142, and an inclined slide section 3143. The height of the high part 3141 is higher than that of the low part 3142. At the height of 142, the first end of the inclined slide section 3143 is connected to the high position 3141, and the second end of the inclined slide section 3143 is connected to the low position 3142. The inclined slide section 3143 is configured to obliquely connect the high position 3141 and the low position 3142. When the track wheel 315 abuts against the high position 3141, the carrier 32 is in a high position. When the track wheel 315 abuts against the low position 3142, the carrier 32 is in a low position, so as to cooperate with the carrier 32 to place the pallet 40 on the conveying surface of the conveying assembly 10.

[0040] Specifically, the drive unit 311 may be a cylinder, a motor, or a drive module with linear stroke.

[0041] As can be seen, through the cooperation of the drive unit 311, the transverse component 312, the track plate assembly and the track wheel assembly, the track wheel 315 is made to slide obliquely in the track groove 314, thereby driving the bearing component 32 to rise and fall, providing a second drive component 31 with precise guidance control and stable and reliable operation.

[0042] In one implementation, each track plate 313 has two track grooves 314, which are spaced apart along a first direction. Two sets of track wheels are provided, with the two track grooves 314 at the same position on the two track plates 313 corresponding to one set of track wheels.

[0043] In one embodiment, guide components are vertically arranged at the four corners of the support base 310. The guide components include guide rods 33 and guide sleeves 34. The bottom of the guide sleeve 34 is fixedly arranged on the support base 310, and the bottom of the guide rod 33 is movably arranged inside the guide sleeve 34. The top of the guide rod 33 is fixedly connected to the support member 32.

[0044] As can be seen, the guide components are set at the four corners of the support 310 to guide the support member 32. On the one hand, this ensures that the support member 32 moves in the predetermined vertical direction, and on the other hand, it avoids the phenomenon of the support member 32 shaking or deviating, thus providing a guide component with good stability.

[0045] In one embodiment, at least one set of positioning components is provided on the end face of the carrier 32. Each set of positioning components includes two upwardly extending positioning protrusions 35. The two positioning protrusions 35 are spaced apart along a first direction. A positioning hole is provided at the bottom of the tray 40 corresponding to the positioning protrusion 35. When the carrier 32 abuts against the bottom of the tray 40, the positioning protrusion 35 is inserted into the corresponding positioning hole, thereby positioning the tray 40.

[0046] As can be seen, by cooperating with the positioning protrusion 35 and the positioning hole at the bottom of the pallet 40, the position of the pallet 40 can be accurately defined when the bearing member 32 abuts against the bottom of the pallet 40, ensuring that the pallet 40 is in a precise set position, effectively avoiding positional deviation of the pallet 40, and providing a positioning component with high positioning accuracy and small space occupation.

[0047] In one embodiment, a sliding guide pair 36 is provided between the transverse member 312 and the support seat 310. The sliding guide pair 36 includes a linear guide rail 360 and a slider 361. The linear guide rail 360 is fixedly fixed to the bottom of the support seat 310 along a first direction, and the slider 361 is fixedly disposed on the transverse member 312 and slidably sleeved on the linear guide rail 360.

[0048] As can be seen, the cooperation between the linear guide rail 360 and the slider 361 can provide precise guidance for the movement of the transverse component 312, avoid deviation, and ensure the accuracy and stability of the transverse component 312 during movement.

[0049] In one embodiment, the conveying assembly 10 includes a third drive assembly, a first conveyor belt 11, and two conveyor frames 12 extending along a first direction. The two conveyor frames 12 are spaced apart along a second direction. The third drive assembly includes a drive motor 13, a drive wheel 14, a first transmission belt 15, two first driven wheels 16, and two second driven wheels 17. Each first driven wheel 16 is rotatably mounted at a first end of a conveyor frame 12 along the first direction, and each second driven wheel 17 is rotatably mounted at a second end of a conveyor frame 12 along the first direction. The two first driven wheels 16 are concentrically connected via a coupling. The first conveyor belt 11 is sleeved on the first driven wheel 16 and the second driven wheel 17. The first conveyor belt 11 is configured to convey the pallet 40 along the first direction. The fixed end of the drive motor 13 is mounted on the conveyor frame 12. The drive end of the drive motor 13 is connected to the drive wheel 14. The drive motor 13 is configured to drive the drive wheel 14 to rotate. The first transmission belt 15 is sleeved on the drive wheel 14 and the first driven wheel 16. The drive motor 13 drives the drive wheel 14 to rotate, so as to drive the first driven wheel 16 to rotate through the first transmission belt 15, and then cooperate with the second driven wheel 17 to drive the first conveyor belt 11 to rotate.

[0050] Specifically, a displacement sensor 18 is installed on the conveyor frame 12 at the loading station. After the displacement sensor 18 senses that the pallet 40 has moved to the loading station, it transmits a signal to the conveyor assembly 10. The conveyor assembly 10 stops at the loading station, at which point the pallet 40 is located at the loading station.

[0051] In one embodiment, the tray 40 includes a plurality of spaced-apart bases 43, each base 43 corresponding to a first strip clip 41, and a magnetic attraction component 44 is provided between the base 43 and the first strip clip 41. The magnetic attraction component 44 is configured to attract and fix the first strip clip 41 onto the base 43 so as to position the first strip clip 41 in the vertical direction.

[0052] As can be seen, by setting a magnetic suction component 44 between the base 43 and the first material strip clip 41, the magnetic suction component 44 attracts and fixes the first material strip clip 41 to the base 43 and positions the clip body in the vertical direction, making disassembly and assembly simple and saving time and effort when changing the clip.

[0053] Based on the above-mentioned material tray feeding mechanism, a material strip receiving machine is provided, including the material tray feeding mechanism.

[0054] The above-mentioned material tray feeding mechanism performs the following steps during operation:

[0055] S1, a manual or robotic arm places a tray 40 containing several first material belt clips 41 on the conveying assembly 10, and each first material belt clip 41 contains a tray 42 full of material.

[0056] S2, the conveying assembly 10 receives the pallet 40 and conveys the received pallet 40 to the loading station along the first direction;

[0057] S3, the drive unit 311 drives the transverse member 312 to move along the first direction, so that the track wheel 315 abutting against the low position 3142 moves obliquely to the high position 3141, driving the bearing member 32 to a high position, thereby pushing the pallet 40 of the loading station away from the conveying surface of the conveying assembly 10.

[0058] S4, the first drive assembly 20 drives the carrier 32, which is in a high position, to move forward one step at a time along the first direction, so as to move the first material strip clip 41 on the pallet 40 to the material picking station in sequence, thus completing the loading.

[0059] S5, the external handling mechanism takes away the first material strip clip 41 of the full material tray 42 located at the material picking station and places it at the receiving platform, and then performs subsequent operations. After the material strip on the full material tray 42 is used up, the external handling mechanism transports the first material strip clip 41 of the empty material tray 42 to the material picking station.

[0060] S6, after all the trays 42 are used up, the drive unit 311 drives the transverse member 312 to move along the other end of the first direction, so that the track wheel 315 abutting against the high position 3141 moves obliquely to the low position 3142, driving the carrier member 32 to a low position, and then cooperating with the carrier member 32 to place the tray 40 on the conveying surface of the conveying assembly 10.

[0061] S7, the conveying assembly 10 conveys the pallet 40 along the first direction to the unloading station, and the manual or robotic arm takes out the first material clip 41 carrying the empty material tray 42 to complete the unloading.
