Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0124] like Figure 1 As shown, the automatic parts loading machine of the present invention includes a material tray conveying device 10, a material tray 20 is conveyed on the upper surface of the material tray conveying device 10, an automatic material sorting device 30 is connected above the material tray conveying device 10, and an automatic loading device 40 is connected to the automatic material sorting device 30.

[0125] As an example, such as Figures 2 to 4As shown, the tray conveying device 10 includes a tray conveying structure 11 for conveying trays 20. The tray conveying structure 11 includes a conveying support base 111, on which a belt conveying unit 112 is mounted. The belt conveying unit 112 conveys the trays 20 to the tray pushing structure 12. The belt conveying unit 112 includes a gear transmission assembly 1121, located on the upper surface of the conveying support base 111. A tray motor 113 is driven and connected to a gear located at the outlet of the tray conveying structure 11 in the gear transmission assembly 1121. The tray motor 113 provides power to the operation of the gear transmission assembly 1121, thereby driving the transmission belt 1122 mounted on the gear transmission assembly 1121 to convey the trays 20 to the tray pushing structure 12. The upstream inlet of the tray pushing structure 12 is connected to the outlet of the tray conveying structure 11. The tray pushing structure 12 is used to slowly push the trays 20 to the bottom of the automatic loading device 40 for parts packaging. The material tray pushing structure 12 includes a pushing support base 121, which includes a support frame 1211. One end of the support frame 1211 is connected to the lower surface of the support plate 1212, and the other end of the support frame 1211 is connected to a foot assembly 1213. The foot assembly 1213 is used to adjust the height of the support frame 1211 so that the support plate 1212 is in a horizontal state for better use. The upper surface of the support plate 1212 has two parallel elongated slots 1214 on both sides. The lower surface of the support plate 1212 is fixed with an X-axis slide assembly 122. The X-axis slide assembly 122 has an X-axis motor 1221. The X-axis motor 1221 has an X-axis slide 1222. An X-axis slider 1223 is slidably connected to the X-axis slide 1222. The base plate 1231 of the push rod assembly 123 is fixed on the X-axis slider 1223. Push rods 1232 are fixed on both sides of the upper surface of the base plate 1231. The two push rods 1232 are respectively inserted into the elongated slots 1214 on both sides of the support plate 1212 of the push support base 121. The push rods 1232 can move back and forth along the elongated slots 1214. It should be noted that the push rods 1232 are mainly used to slowly push the material tray 20 toward the automatic loading device 30. A Z-axis lifting assembly 124 is fixed to the lower part of the push rod assembly 123. The Z-axis lifting assembly 124 includes two Z-axis servo cylinders 1241, which are respectively fixed to both ends of the lower surface of the base plate 1231. Each Z-axis servo cylinder 1241 has a Z-axis slide rod 1242, and the push rod 1232 is connected to the slide rod 1242. The Z-axis servo cylinder 1241 provides power for the lifting and lowering of the slide rod 1242, thereby driving the push rod 1232 to perform the lifting and lowering process.

[0126] A tray detection unit 125 is also provided on the upper surface of the support plate 1212 of the propulsion support base 121. The tray detection unit 125 includes a tray shortage detection sensor 1251 disposed on the upstream side wall of the upper surface of the support plate 1212. The tray shortage detection sensor 1251 is used to detect whether there is a tray 20 in place on the tray propulsion structure 12 within a set time. A tray arrival detection sensor 1252 is installed on the middle side wall of the upper surface of the support plate 1212, near the automatic loading device 40. The tray arrival detection sensor 1252 is used to detect whether a tray 20 has arrived below the automatic loading device 40 for parts packaging. It should be noted that the tray arrival detection sensor 1252 is signal-connected to the tray motor 113 of the tray conveying structure 11. When the tray arrival detection sensor 1252 detects that the tray 20 has arrived below the automatic loading device 40, the tray motor 113 stops operating, and the X-axis slide assembly 122 of the tray pushing structure 12 starts operating. When the push rod assembly 123 fixed on the X-axis slide assembly 122 is moved to a fixed position at a set speed, the Z-axis lifting assembly 124 operates to raise the two push rods 1232 and proceed to the next operation. When the tray arrival detection sensor 1252 detects that the tray 20 has completed the part loading, the tray motor 113 continues to operate, pushing the next tray 20 to its position. The tray propulsion structure 12 then repeats the above operation to assist the tray 20 in completing the part loading. This process is repeated to achieve automatic part loading, greatly improving work efficiency. A full tray detection sensor 1253 is provided at the downstream outlet of the support plate 1212 of the propulsion support base 121. The full tray detection sensor 1253 is used to detect the arrival status of the tray after the part loading operation is completed.

The side strips 22 are connected to the sides of the flat bottom 21 via connecting blocks 24. Limiting blocks 25 are provided at the two corners of the same side of the flat bottom 21, ensuring that the two corners of the flat bottom 21 are precisely contained within the two limiting blocks 25. Simultaneously, when the blister tray 26 is placed on the flat bottom 21 of the material tray 20, the limiting blocks 25 provide a limiting and fixing function for the placement of the blister tray 26. When the material tray 20 is slowly advanced from the material tray conveying structure 11 to the material tray pushing structure 12, the two limiting blocks 25 are respectively located on the elongated slots 1214 on both sides of the support plate 1212 of the pushing support base 121, and are pushed and moved by the pushing rod 1232 of the pushing rod assembly 123. Figure 1 As shown, the blister tray 26 has uniformly arranged rectangular grooves 261 for loading parts. In this embodiment, the blister tray 26 is provided with 10 columns and 10 rows of 100 rectangular grooves.

[0128] As an example, such as Figure 1 , Figure 6 and Figure 7 As shown, the automatic material handling device 30 includes a tilting frame 31, which includes a tilting plate 311. Several support columns 312 are respectively installed on the upper ends of both sides of the tilting plate 311. The support columns 312 have different heights, thus adjusting the tilt angle of the tilting plate 311 and supporting the tilting plate 311. The lower ends of the support columns 312 are connected and fixed to the upper surface of the support plate 1212 of the push support base 121 of the tray conveying device 10. Therefore, the automatic material handling device 30 is placed above the tray conveying device 10 at a certain tilt angle. A square hopper 32 for holding parts is fixed on the upper surface of the inclined plate 311. A guide structure 33 is provided at the bottom of the square hopper 32. The guide structure 33 is used to guide parts from the upstream of the square hopper 32 to the downstream of the square hopper 32. The guide structure 33 includes a parts bin 331 located at the upper bottom of the square hopper 32. Upstream of the parts bin 331, there are several material dispersing blocks 3311 for dispersing parts. Downstream of the parts bin 331, there are several separating cone blocks 3312 for separating parts from each other individually. Downstream of the parts bin 331, there is a guide unit 332 connected. The guide unit 332 is used to slide the individual parts separated by the separating cone blocks 3312 from the upstream of the square hopper 32 to the downstream of the square hopper 32. The guiding unit 332 is located at the lower half of the square hopper 32. The guiding unit 332 has N parallel part slides 3321, where N ≥ 2 and N is a natural number. In this embodiment, the guiding unit 332 has 10 parallel part slides 3321, and each part slide 3321 allows only a single row of parts to slide down. A pushing structure 34 is provided above the guiding unit 332 in the middle and lower reaches of the square hopper 32. The pushing structure 34 is used to push the parts in the part slides 3321 flat.

[0129] The pushing structure 34 includes a push plate unit 341 located in the middle of the square hopper 32 and a push rod unit 342 connected to the push plate unit 341 and located downstream of the square hopper 32. The push plate unit 341 has two push plate limiting rods 3411 parallel to the two side plates of the square hopper 32. The two push plate limiting rods 3411 are fixed between the two side plates of the square hopper 32 by an upper limiting plate 3412 and a lower limiting plate 3413. Push plates 3414 are sleeved on the two push plate limiting rods 3411, and the lower surface of the push plates 3414 is parallel to the plane formed by the part slide 3321. It should be noted that the push plate limiting rod 3411 has an inner shaft rod 3411a, the two ends of which are fixed to the upper limiting plate 3412 and the lower limiting plate 3413, respectively. An outer sleeve rod 3411b is slidably fitted on the inner shaft rod 3411a, and the two ends of the outer sleeve rod 3411b are fixed to the vertical plate 3414a and the inclined plate 3414b of the push plate 3414. The push plate 3414 has a vertical plate 3414a that is vertically arranged above the part slide rail 3321. The bottom edge of the vertical plate 3414a is connected to one side of a horizontal plate 3414c that is parallel to the part slide rail 3321. The other side of the horizontal plate 3414c is connected to the bottom edge of the inclined plate 3414b. The top edge of the inclined plate 3414b is connected to the upper part of the vertical plate 3414a. In this embodiment, the push plate 3414 has a right-angled triangle cross-section. It should be noted that the push plate can also be any other shape that can achieve the purpose of this invention. The push rod unit 342 includes two eccentric turntables 3421, which are respectively connected to the two side plates of the square bucket 32 ​​at the downstream outlet. A feeding motor 3422 is connected to one of the eccentric turntables 3421, and the feeding motor 3422 is used to provide power for the rotation of the eccentric turntable 3421. A connecting rod 3423 perpendicular to the side plate direction is connected to the two eccentric turntables 3421 at the offset point from the center. One end of the push rod 3424 is passed through the connecting rod 3423, and the other end of the push rod 3424 is connected to the side of the vertical plate 3414a of the push plate 3414. In this way, when the eccentric turntable 3421 rotates under the action of the feeding motor 3422, the push rod 3424 connected to the connecting rod 3423 can drive the push plate 3414 to move back and forth repeatedly within the limited range of the two push plate limiting rods 3411, thereby pushing out the excess parts on the single part slide 3321.

[0130] As an example, such as Figures 8 to 10As shown, the automatic loading device 40 includes a guide plate 41 for introducing parts. The guide plate 41 is fixed to the lower part of the inclined plate 311 of the inclined frame 31 of the automatic feeding device 30 and is connected to the guiding unit 332 of the automatic feeding device 30. The guide plate 41 has N guide grooves 411 for introducing parts into the rotating chamber 42, where N≥2 and N is a natural number. In this embodiment, the number of guide grooves 411 on the guide plate 41 corresponds to the number of part slides 3321 in the guiding unit 332. That is, the guide plate 41 is provided with 10 guide grooves 411. The inlet of the guide groove 411 corresponds one-to-one with the outlet of the part slide 3321. It should be noted that in order to make the outlet of the guide groove 411 correspond to the storage position 422 of the rotating chamber 42 designed in this invention, the guide plate 41 of this invention is generally outwardly expanded. Above the guide plate 41, an auxiliary plate 412 is provided to prevent parts from jumping up during the sliding process. The auxiliary plate 412 covers the guide groove 411 and can press down the parts that slide down in the guide groove 411. Downstream of the guide plate 41, a rotating chamber 42 is connected at an angle above it, and a material discharge auxiliary device 43 is connected at an angle below it. The rotating chamber 42, which is used to load parts from the guide plate 41, has N rows and M rows of storage positions 422 evenly arranged in the circumferential direction. The storage positions 422 correspond one-to-one with the outlets of the guide grooves 411 of the guide plate 41, where M and N ≥ 2 and M and N are natural numbers. It should be noted that the rotating chamber 42 consists of N parallel storage trays 421, and the storage trays 421 have M rows of storage positions 422 evenly distributed in the circumferential direction. In this embodiment, the rotating chamber 42 consists of 10 cylindrical storage trays 421. The thickness of the storage tray 421 is 2.5 times the diameter of the part. Ten cylindrical storage positions 422 are evenly distributed along the circumference on the cylindrical surface of the storage tray 421. In other words, the rotating chamber 42 in this embodiment has 100 storage positions 422 arranged in 10 columns and 10 rows in the circumferential direction. It should be noted that the volume of the storage position 422 is slightly larger than the volume of the part so that the part from the guide groove 411 of the guide plate 41 can smoothly slide into the storage position 422. The material dropping auxiliary device 43 for assisting the parts in the rotating chamber 42 to fall into the material tray 20 conveyed by the material tray conveying device 10 includes a rotating chamber wall 431. The rotating chamber wall 431 is used to prevent the parts in the storage positions 422 from sliding outward in an unsuitable position. A material discharge auxiliary unit 432 is fixedly connected to the rotating chamber wall 431. The material discharge auxiliary unit 432 is provided with N material discharge ports 4321, where N≥2 and N is a natural number. The inlets of the material discharge ports 4321 correspond one-to-one with the material storage positions 422 of the rotating chamber 42, and the outlets of the material discharge ports 4321 correspond one-to-one with the rectangular grooves of the blister trays 26 placed on the material tray 20. In this embodiment, the material discharge auxiliary unit 432 is provided with 10 material discharge ports 4321.Meanwhile, a large gear 44 is connected to each side of the rotating chamber 42, and a damper 45 is connected to each of the two large gears 44 on the side away from the rotating chamber 42. The damper 45 is used to prevent the two large gears 44 from rotating on their own due to the weight of the parts inside the rotating chamber 42. The automatic loading device 40 also has two connecting plates 46. The middle part of the connecting plate 46 passes through the rotating shaft of the rotating chamber 42. The upper end of the connecting plate 46 is connected to the side wall of the guide plate 41 and fixed to the inclined plate 311 of the inclined frame 31 of the automatic material handling device 30. The lower end of the connecting plate 46 is connected to the rotating chamber wall 431 of the unloading auxiliary device 43.

[0131] In one embodiment, the power supply of the automatic parts loading machine is turned on, and the parts are manually placed into the parts bin 331 of the automatic material handling device 30. Since the automatic material handling device 30 is inclined and set above the material tray conveying device 10, the parts will automatically move along the inclined direction of the square bucket 32 ​​towards the automatic loading device 40 downstream of the square bucket 32 ​​under the action of their own gravity. During the sliding process of the parts, several unloading blocks 3311 upstream of the parts bin 331 disperse the parts to several separating cones 3312 downstream of the parts bin 331. The separating cones 3312 separate the parts individually into the corresponding parts slides 3321, and the parts further slide down the parts slides 3321 towards the automatic loading device 40 downstream of the square bucket 32. It should be noted that, in order to facilitate the operation of the automatic loading device 40, a single part slide 3321 only allows a single row of parts to slide down the automatic loading device 40 one after the other. However, in actual operation, multiple parts stacked together may slide down the same way or the parts may be tilted up on a single part slide 3321, which may affect the operation of the subsequent automatic loading device 40. In order to avoid this situation, a pusher structure 34 is provided above the part slide 3321 to push the stacked or tilted parts flat into the part slide 3321. The feeding motor 3422 in the feeding structure 34 operates and drives the two eccentric turntables 3421 connected to it to rotate. The connecting rod 3423 between the two eccentric turntables 3421 also rotates, thereby driving the push rod 3424 fixed on the connecting rod 3423 to move back and forth reciprocally. The push plate 3414 connected to the push rod 3424 also moves back and forth repeatedly within the range limited by the two push plate limiting rods 3411. During the forward movement of the push plate 3414, the horizontal plate 3414c parallel to the part slide 3321 pushes the excess or raised parts in a single part slide 3321 to other part slides 3321 or the same part slide 3321. The parts that are pushed into the part slide 3321 continue to slide down towards the automatic loading device 40 under the action of their own gravity. The parts in the parts slide 3321 eventually slide down into the corresponding guide groove 411 on the guide plate 41 of the automatic loading device 40 under their own gravity, and then slide down into the storage position 422 corresponding to the rotating chamber 42.

[0132] After the parts to be loaded onto the tray are placed, the rectangular blister tray 26 is manually fixed on the tray 20 according to the position of the limit block 25 on the tray 20. Then, 3 to 4 trays 20 with blister trays 26 are placed on the conveyor belt 1122 of the tray conveyor structure 11. The tray motor 113 is started, and the gear transmission assembly 1121 operates, thereby driving the conveyor belt 1122 on the gear transmission assembly 1121 to transport the trays 20 to the upstream inlet of the tray pusher structure 12. The previous tray 20 on the support plate 1212 of the pusher support base 121 of the tray pusher structure 12 moves slowly towards the automatic loading device 40 under the push of the next tray 20. When the previous tray 20 reaches the position below the rotating chamber 42, the tray arrival detection sensor 1252 of the tray detection unit 125 detects that the tray 20 has arrived. At this time, the tray motor 113 stops operating, and the tray pusher structure 12 starts working. The X-axis motor 1221 in the material tray propulsion structure 12 runs at a set speed. After the X-axis slider 1223 carrying the Z-axis servo cylinder 134 moves to the limit block 25 of the material tray 20 on the X-axis slide table 1222, the Z-axis slide rod 1242 on the Z-axis servo cylinder 1241 rises. The push rod 1232 connected to the Z-axis slide rod 1242 passes through the long slot 1214 on the support plate 1212 of the propulsion support base 121 and makes surface contact with the limit block 25 of the material tray 20. Subsequently, the X-axis slider 1223 moves towards the automatic loading device 40 under the action of the X-axis motor 1221. During this process, the push rod 1232 slowly pushes the material tray 20 towards the automatic loading device 40. The racks 23 on both sides of the slowly pushed material tray 20 mesh with the two large gears 44 of the automatic loading device 40. The large gears 44 rotate counterclockwise at a certain speed during the meshing process with the racks 23, thereby driving the rotating chamber 42 connected to the two large gears 44 to rotate. While the rotating chamber 42 is rotating, the parts in the guide groove 411 slide down into the storage position 422 of the rotating chamber 42 under their own gravity and rotate with the rotation of the rotating chamber 42. When the storage position 422 containing the parts rotates to the opposite side of the guide groove 411, the parts in the storage position 422 begin to slide outward under their own weight, but are restricted by the rotating chamber wall 431 of the unloading auxiliary device 43. The rotating chamber 42 continues to rotate. When the parts in the storage position 422 on the rotating chamber 42 align with the unloading port 4321 of the unloading auxiliary device 43, the parts in the storage position 422 begin to slide down and slide through the corresponding unloading port 4321 from the rotating chamber 42 into the corresponding rectangular groove 261 in the blister tray 26 on the material tray 20. Then the rotating chamber 42 continues to rotate, and the parts in the guide groove 411 continue to slide down to the corresponding storage position 422 on the rotating chamber 42 in sequence. As the rotating chamber 42 rotates, the parts in the storage position 422 slide down onto the material tray 20 until all parts are loaded onto the tray.

[0133] It should be noted that during the automatic pallet loading process, when the pallet position detection sensor 1252 detects that the pallet 20 has been loaded, the pallet motor 113 continues to operate, pushing the pallet 20 on the conveyor belt 1122 of the pallet conveying structure 11 further towards the pallet pushing structure 12. This pushes the pallet 20, which is still on the pushing support base 121 of the pallet pushing structure 12 and is the one after the pallet 20 that has completed the loading operation, to continue moving towards the automatic loading device 40. When the pallet position detection sensor 1252 detects that a pallet 20 has arrived again, the pallet motor 113 stops operating again, and the pallet pushing structure 12 restarts. When the tray 20 with completed parts loading moves to the downstream outlet of the tray propulsion structure 12 under the pushing action of the other trays 20 with completed parts loading, the full tray detection sensor 1253 will detect the completed tray 20. In other words, the support plate 1212 of the propulsion support base 121 is filled with completed trays 20 and trays 20 to be loaded from the upstream inlet to the downstream outlet. At this time, the tray propulsion structure 12 will stop working, and the full tray detection sensor 1253 will issue an audible and visual alarm to prompt manual removal of the completed trays 20. After the completed trays 20 are manually removed, the tray propulsion structure 12 will continue to work. The function of the material shortage tray detection sensor 1251 is to detect whether the material tray 20 has arrived within a set time. If the material shortage tray sensor 1251 does not detect the presence of the material tray 20 within the set time, the material shortage tray sensor 1251 will issue an audible and visual alarm to prompt manual placement of the material tray 20. Once the material tray 20 is placed in place, the audible and visual alarm issued by the material shortage tray sensor 1251 will automatically disappear.
