Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0066] The existing unloading mechanism has a low degree of automation and requires many processes to be manually assisted, resulting in low unloading efficiency and high labor intensity for operators.

[0067] The following is a preferred embodiment of a clip-type automatic unloading device provided by the present invention that can solve the above technical problems.

[0068] Please refer to Figures 1-9 A preferred embodiment of the present invention provides a magazine-type automatic unloading device, comprising a frame 1, a work platform 2, a pre-discharge rail conveyor mechanism 3, a discharging gripper arm 4, a clamping and lifting mechanism 5 for the magazine to be tested, a conveyor mechanism 6 for empty magazines to be tested, and a receiving mechanism 7 for the magazine to be tested, all disposed on the frame 1. The work platform 2 and the pre-discharge rail conveyor mechanism 3 are arranged horizontally, while the pre-discharge rail conveyor mechanism 3 and the clamping and lifting mechanism 5 for the magazine to be tested are arranged longitudinally. The conveying direction of the empty magazine conveyor mechanism 6 for empty magazines to be tested and the receiving mechanism 7 for empty magazines to be tested are both horizontal, and both are arranged vertically and in parallel. The discharge end of the empty magazine conveyor mechanism 6 for empty magazines to be tested and the feed end of the receiving mechanism 7 for empty magazines to be tested are located on the same side. The work platform 2 is used to place processed circuit boards. The pre-discharge rail conveyor mechanism 3 is used to receive and transport the circuit boards on the work platform 2. The discharging gripper arm 4 is used to move the circuit boards from the work platform 2 to the pre-discharge rail conveyor mechanism 3.

[0069] The test clip holding and lifting mechanism 5 is positioned adjacent to the discharge end of the empty test clip conveying mechanism 6 and the infeed end of the test board receiving mechanism 7. The test clip holding and lifting mechanism 5 comprises a test board clamping assembly 51, a test board telescoping assembly 52, and a test board lifting assembly 53. The test board clamping assembly 51 is used to hold a clip 8, which has two longitudinal openings and is used to support the test circuit board conveyed by the pre-discharge track conveying mechanism 3. The test board telescoping assembly 52 is connected to the test board clamping assembly 51 and controls the lateral movement of the test board clamping assembly 51 to remove an empty clip 8 from the test board empty clip conveying mechanism 6 and place a loaded clip 8 onto the test board receiving mechanism 7. The test board lifting assembly 53 is connected to the test board telescoping assembly 52 and controls the vertical movement of the test board telescoping assembly 52 and the test board clamping assembly 51.

[0070] The test plate lifting assembly 53 is fixed to the frame 1. The test plate telescopic assembly 52 and the test plate clamping assembly 51 are located on the same side of the test plate lifting assembly 53, so that the test plate lifting assembly 53 drives the test plate telescopic assembly 52 and the test plate clamping assembly 51 to move upward together. The test plate clamping assembly 51 is located above the test plate telescopic assembly 52, so that the test plate telescopic assembly 52 can provide a certain amount of support for the test plate clamping assembly 51, ensuring the stability of the test plate clamping assembly 51 after clamping the magazine 8. The clamping opening of the test plate clamping assembly 51 is horizontally oriented toward the test plate receiving mechanism 7 and the test plate empty magazine conveying mechanism 6. When the test plate telescopic assembly 52 drives the test plate clamping assembly 51 to move horizontally, the clamping opening of the test plate clamping assembly 51 can penetrate into the test plate empty magazine conveying mechanism 6 or the test plate receiving mechanism 7 to facilitate clamping or releasing the magazine 8. The clamping opening of the test plate clamping assembly 51 is arranged to open and close vertically so as to clamp the clip 8 from both ends.

[0071] The test plate lifting assembly 53 includes a lifting drive 531 and a lifting drive block 532. The lifting drive 531 is vertically mounted and fixed to the frame 1, driving the lifting drive block 532 to move vertically. The lifting drive 531 is a vertically mounted servo motor module that facilitates control and improves vertical movement stability.

[0072] The test plate telescopic assembly 52 includes a telescopic drive member 521, a telescopic drive block 522, a linear guide 523, two connecting plates 524, and an upper plate 525. The telescopic drive member 521 is a horizontally arranged cylinder used to drive the telescopic drive block 522 to move laterally. The linear guide 523 connects the telescopic drive member 521 and the telescopic drive block 522, ensuring stable sliding of the telescopic drive block 522. The two connecting plates 524 are parallel and arranged opposite each other in the longitudinal direction and are both connected to the telescopic drive member 521. One of the connecting plates 524 is also connected to the lifting drive block 532, allowing the lifting drive block 532 to drive the telescopic drive member 521 to move vertically. The upper plate 525 is fixedly connected to the top of the two connecting plates 524 and forms a movable space for the test plate clamping assembly 51 to prevent the movement of the test plate clamping assembly 51 from being interfered with by other objects.

[0073] The test plate clamping assembly 51 is positioned between two connecting plates 524 and comprises a cylinder 511, two sets of piston rods 512, and two sets of clamping wheels 513. The cylinder 511 is connected to a telescopic drive block 522, enabling the telescopic drive block 522 to drive the cylinder 511 in lateral motion. One set of piston rods 512 protrudes vertically from the upper end of the cylinder 511, while the other set of piston rods 512 protrudes vertically from the lower end of the cylinder 511. The two sets of clamping wheels 513 are connected to the two sets of piston rods 512, respectively, and extend laterally toward the test plate empty magazine conveying mechanism 6 and the test plate receiving mechanism 7. The test plate telescopic assembly 52 drives the test plate clamping assembly 51 to move laterally, allowing the two sets of clamping wheels 513 to extend into the upper and lower sides of the clip 8, respectively. The two sets of piston rods 512 simultaneously retract inward, driving the two sets of clamping wheels 513 toward each other to clamp the clip 8. The two sets of piston rods 512 simultaneously extend outward, driving the two sets of clamping wheels 513 away from each other to release the clip 8. This structure ensures that the clamping wheels 513 can hold the clip 8 stably.

[0074] The empty magazine conveying mechanism 6 for the test board is used to convey empty magazines 8. The test board receiving mechanism 7 is used to convey magazines filled with test circuit boards 8. In each figure, x is the horizontal direction, y is the longitudinal direction, and z is the vertical direction, and the three directions are perpendicular to each other.

[0075] The magazine-type automatic unloading device of the present invention, during operation, moves the circuit board on the working platform 2 to the pre-discharging track conveying mechanism 3 through the discharging grab plate arm 4, and conveys the empty magazine 8 in the horizontal direction toward the direction close to the magazine holding lifting mechanism 5 of the magazine to be tested by the empty magazine conveying mechanism 6 of the magazine to be tested. The magazine telescopic assembly 52 of the magazine to be tested drives the clamping assembly 51 of the magazine to be tested to extend in the horizontal direction to the discharging end of the empty magazine conveying mechanism 6 of the magazine to be tested and clamps the empty magazine 8. Then, the telescopic assembly 52 of the magazine to be tested drives the clamping assembly 51 of the magazine to be tested to retract in the horizontal direction, and the pre-discharging track conveying mechanism 3 conveys the circuit board to the magazine 8 clamped by the clamping assembly 51 of the magazine to be tested. The lifting assembly 53 of the magazine to be tested drives the magazine 8 to move vertically to fill the magazine 8 with the circuit board. The telescopic assembly 52 of the magazine to be tested drives the clamping assembly 51 of the magazine to be tested to extend in the horizontal direction and places the magazine 8 filled with the circuit board on the feeding end of the magazine receiving mechanism 7 of the magazine to be tested, and the magazine receiving mechanism 7 of the magazine to be tested outputs the magazine 8 in the horizontal direction. The magazine-type automatic unloading device of the present invention can automatically input an empty magazine 8, and automatically load the circuit board on the working platform 2 into the magazine 8 and then output it without manual assistance, and has high unloading efficiency.

[0076] Please refer to Figure 1 and Figure 2 The clip-type automatic unloading device also includes a post-discharge track conveying mechanism 9, a good board clip clamping and lifting mechanism 10, a good board empty clip conveying mechanism 20, and a good board receiving mechanism 30. The post-discharge track conveying mechanism 9 is connected to the top of the test board telescopic assembly 52 and is used to receive and convey the good boards delivered by the pre-discharge track conveying mechanism 3. The good plate clip clamping and lifting mechanism 10 is arranged adjacent to the discharge end of the post-discharge track conveying mechanism 9. The good plate clip clamping and lifting mechanism 10 includes a good plate clamping assembly, a good plate telescopic assembly and a good plate lifting assembly. The good plate clamping assembly is used to clamp the clip 8, and the clip 8 is used to carry the good plates conveyed by the post-discharge track conveying mechanism 9. The good plate telescopic assembly is connected to the good plate clamping assembly and is used to control the good plate clamping assembly to move horizontally to remove the empty clip 8 from the good plate empty clip conveying mechanism 20 and place the clip 8 filled with good plates on the good plate receiving mechanism 30; the good plate lifting assembly is connected to the good plate telescopic assembly and is used to control the good plate telescopic assembly and the good plate clamping assembly to move vertically. The specific structure of the good plate clip clamping and lifting mechanism 10 can refer to the clip clamping and lifting mechanism 5 to be tested, and the structures of the two are the same.

[0077] The conveying directions of the good plate empty magazine conveying mechanism 20 and the good plate receiving mechanism 30 are both horizontal, and the two are arranged in parallel vertically. The discharge end of the good plate empty magazine conveying mechanism 20 and the feeding end of the good plate receiving mechanism 30 are located on the same side, and are both adjacent to the good plate magazine clamping lifting mechanism 10.

[0078] In the above structure, when the circuit board is a good board, the discharge board grabbing arm 4 moves the good board on the working platform 2 to the front discharge track conveying mechanism 3, and the board to be tested lifting assembly 53 drives the rear discharge track conveying mechanism 9 to move vertically, so that the rear discharge track conveying mechanism 9 is flush with the front discharge track conveying mechanism 3, and the good board is conveyed from the front discharge track conveying mechanism 3 to the rear discharge track conveying mechanism 9, and the good board empty magazine conveying mechanism 20 moves the empty magazine 8 horizontally and close to the good board magazine clamping lifting mechanism 10 The good plate is transported in the direction of , the good plate telescopic assembly drives the good plate clamping assembly to move horizontally, the good plate clamping assembly clamps the empty magazine 8 from the good plate empty magazine conveying mechanism 20 and retreats, and after the material is discharged, the track conveying mechanism 9 conveys the good plate to the magazine 8 clamped by the good plate clamping assembly, the good plate lifting assembly drives the magazine 8 to move vertically, and fills the magazine 8 with good plates, the good plate telescopic assembly drives the good plate clamping assembly to move horizontally, and places the magazine 8 filled with good plates on the good plate receiving mechanism 30, and outputs it horizontally. With the above structure, the empty magazine 8 can be automatically input, and the good plates on the working platform 2 can be automatically loaded into the magazine 8 and then output, without manual assistance, with high unloading efficiency, so that the good plates and the plates to be tested can be output separately.

[0079] Please refer to Figure 3 The pre-discharge track conveying mechanism 3 includes two side rails 31, two transmission assemblies 32, and a track push plate assembly 33. The two side rails 31 are arranged parallel to and opposite each other. The two transmission assemblies 32 are respectively mounted on the two side rails 31 for conveying circuit boards. The track push plate assembly 33 includes a limiting post 331, a sliding block 332, a rotating block 333, a tension spring 334, and a push plate driver 335. The sliding block 332 is longitudinally slidable on the inner side of the side rail 31. The sliding block 332 has a first position and a second position along its sliding path. The rotating block 333 is rotatably connected to the sliding block 332. The tension spring 334 connects the sliding block 332 and the rotating block 333, and the tension spring 334 is used to provide an elastic force to rotate the rotating block 333 upward. The limiting post 331 is fixed to the inner side of the side rail 31. The limiting post 331 forces the rotating block 333 to rotate downward, so that the rotating block 333 is lower than the circuit board. The push plate driver 335 is connected to the sliding block 332 and is configured to drive the sliding block 332 to slide longitudinally between a first position and a second position. When the sliding block 332 is in the first position, the rotating block 333 is positioned below the retaining post 331. When the sliding block 332 is in the second position, the rotating block 333 is disengaged from the retaining post 331. When the sliding block 332 slides from the first position to the second position, the rotating block 333 contacts the end surface of the circuit board, thereby pushing the circuit board away from the two transmission assemblies 32. The push plate driver 335 may be a pneumatic cylinder. Figure 3 In the embodiment, the two transmission assemblies 32 transport the circuit board to the right, and the rotating block 333 pushes the circuit board to the right.

[0080] In the above structure, when the circuit board is normally conveyed through the two transmission assemblies 32, the push plate driver 335 drives the rotating block 333 to move below the limiting post 331. The limiting post 331 causes the rotating block 333 to rotate downward, lowering it below the circuit board and preventing it from being conveyed. When the circuit board is about to completely leave the two transmission assemblies 32, the push plate driver 335 drives the rotating block 333 to move, disengaging the limiting post 331. The tension spring 334 causes the rotating block 333 to rotate upward, bringing it into contact with the end surface of the circuit board, thereby pushing the circuit board. During the process of conveying the circuit board, the two transmission assemblies 32 cannot fully push the circuit board into the clip 8 because the end of the circuit board does not fully enter the clip 8 when it leaves the two transmission assemblies 32. The track push plate assembly 33 can completely push the circuit board into the clip 8.

[0081] The pre-discharge track conveyor mechanism 3 also includes a sensor, located at the discharge end of the pre-discharge track conveyor mechanism 3. The sensor senses the circuit board. When the sensor fails to sense the circuit board, the rotating block 333 extends from the bottom of the limiting post 331 to push the circuit board. In this structure, the sensor sends a signal to control the rotating block 333 to extend at the appropriate time, fully pushing the circuit board into the magazine 8.

[0082] Please refer to Figure 3 、 Figure 4 and Figure 5 Each transmission assembly 32 includes a conveyor belt 321, and the pre-discharging track conveying mechanism 3 also includes a track pressurizing assembly 34, which includes a fixed block 341, a movable block 342, a guide shaft 343, a pressure wheel 344 and a compression spring 345. The fixed block 341 is fixed on the side rail 31, and the fixed block 341 is provided with a movable groove 3411. The guide shaft 343 is vertically arranged in the movable groove 3411. The movable block 342 is vertically movably arranged in the movable groove 3411 and is sleeved on the guide shaft 343. A step hole is vertically provided in the movable block 342. The pressure wheel 344 is rotatably connected to the movable block 342 and is arranged adjacent to the conveyor belt 321. The compression spring 345 is sleeved on the guide shaft 343. One end of the compression spring 345 is located in the step hole, and the other end abuts against the side wall of the movable groove 3411. The elastic force of the compression spring 345 causes the movable block 342 to move downward, and presses the circuit board toward the conveyor belt 321 through the pressure wheel 344 to increase the friction between the circuit board and the conveyor belt 321. In the above structure, the resilience of the compression spring 345 drives the movable block 342 downward along the guide shaft 343, thereby driving the pressure wheel 344 downward, pressing the circuit board toward the conveyor belt 321. This increases the friction between the circuit board and the conveyor belt 321 and prevents the circuit board from slipping on the conveyor belt 321. The pressure wheel 344 is rotatable to prevent the circuit board from getting stuck.

[0083] Please refer to Figure 3 Each transmission assembly 32 further includes a driving wheel 322 and a driven wheel 323. The driving wheel 322 is located at the loading end of the transmission assembly 32, and the driven wheel 323 is located at the unloading end of the transmission assembly 32. The driving wheel 322 and the driven wheel 323 are rotatably mounted at the two ends of the side rail 31, and the conveyor belt 321 is sleeved over the driving wheel 322 and the driven wheel 323. There are four rail pressure assemblies 34, two of which are arranged opposite each other and located between the driving wheel 322 and the driven wheel 323, and the other two are arranged opposite each other and opposite the driven wheel 323. In the above structure, the two pressure wheels 344 between the driving wheel 322 and the driven wheel 323 first press against the circuit board, applying a small amount of pressure to the circuit board. Then, the pressure wheels 344 above the two driven wheels 323 press against the circuit board. The cooperation between the driven wheels 323 and the pressure wheels 344 applies a larger amount of pressure to the circuit board, so that the circuit board is pressed more tightly and conveyed smoothly.

[0084] Please continue to refer to Figure 3 The front track conveying mechanism 3 also includes a width adjustment screw 35, which connects the two side tracks 31. The width adjustment screw 35 is used to adjust the distance between the two transmission assemblies 32. In the above structure, the distance between the two transmission assemblies 32 can be adjusted by the width adjustment screw 35 to adapt to different plate widths.

[0085] The structure of the post-discharge track conveying mechanism 9 is the same as that of the pre-discharge track conveying mechanism 3 , and will not be described in detail here.

[0086] Please refer to Figure 7 The test clip holding and lifting mechanism 5 also includes a limit block 54 connected to the test board telescopic assembly 52, which is used to limit the position of the clip 8 and ensure that the clip 8 moves to the same position. With this structure, there is no need to repeatedly adjust the position of the clip 8 when it retracts. The position of the clip 8 can be matched with the pre-discharge track conveying mechanism 3 each time it retracts, facilitating the transportation of circuit boards.

[0087] Please refer to Figure 2 The clip-type automatic unloading device also includes an NG board placement mechanism 40, which is installed on the frame 1 and located between the work platform 2 and the pre-discharge track conveyor mechanism 3. With this structure, if the circuit board is an NG board, the discharge gripper arm 4 can move the circuit board from the work platform 2 to the NG board placement mechanism 40.

[0088] Please continue to refer to Figure 2 The clip-type automatic unloading device also includes a stacking and receiving placement mechanism 50, which is installed on the frame 1 and adjacent to the side of the pre-discharge track conveyor mechanism 3 facing away from the work platform 2. With this structure, if the circuit boards can be stacked, the discharge gripper arm 4 moves the circuit boards from the work platform 2 to the stacking and receiving placement mechanism 50.

[0089] Please refer to Figure 8 and Figure 9 The clip 8 includes two side panels 81 and two top panels 82. The two side panels 81 are parallel to each other and arranged opposite to each other. The two top panels 82 are parallel to each other and arranged opposite to each other. The two side panels 81 and the two top panels 82 are connected to form a frame structure with two open ends. A plurality of slots 811 are provided on the inner side of the side panels 81. The plurality of slots 811 are arranged vertically and spaced apart. The length direction of each slot 811 is longitudinal and is used to support the edge of the circuit board. With the above structure, when the pre-discharge track conveying mechanism 3 conveys the test boards one by one into the clip 8, the test board lifting assembly 53 controls the clip 8 to move to the same height each time. When the post-discharge track conveying mechanism 9 conveys the good boards one by one into the clip 8, the good board lifting assembly controls the clip 8 to move to the same height each time, which is convenient for control.

[0090] The top plate 82 comprises a first sub-plate 821 and a second sub-plate 822, which slide longitudinally. The first sub-plate 821 is provided with a threaded hole, and the second sub-plate 822 is provided with a U-shaped groove. The second sub-plate 822 is positioned outside the first sub-plate 821, with the threaded hole communicating with the U-shaped groove. In this structure, the first and second sub-plates 821 and 822 can be secured together using screws threaded through the U-shaped groove and threaded hole. The distance between the two side plates 81 can be adjusted by adjusting the position of the threaded hole within the U-shaped groove to accommodate circuit boards of varying widths.

[0091] Please refer to Figure 8 Both ends of the slot 811 are provided with chamfers for facilitating the introduction of the circuit board. With this structure, the circuit board can be placed into the clip 8 more quickly and accurately.

[0092] Please refer to Figure 8 The side plate 81 is provided with a plurality of strip-shaped holes 812, which are parallel to the slots 811 and staggered with each other. In the above structure, the strip-shaped holes 812 can reduce the weight of the magazine 8 without interfering with the slots 811 and preventing the circuit board from being placed in the magazine 8.

[0097] 3. The test plate telescopic assembly 52 drives the test plate clamping assembly 51 to extend horizontally to the discharge end of the test plate empty magazine conveying mechanism 6 and clamp the empty magazine 8. Then, the test plate telescopic assembly 52 drives the test plate clamping assembly 51 to retract horizontally, and the limit block 54 allows the magazine 8 to retract to the same position each time.

[0098] 4. Before unloading, the track conveying mechanism 3 conveys the circuit board to the clip 8 held by the clamping assembly through the transmission assembly 32, and presses the circuit board toward the conveyor belt 321 through the pressure wheel 344 to increase the friction between the circuit board and the conveyor belt 321, thereby preventing the circuit board from slipping on the conveyor belt 321;

[0099] 5. When the circuit board is about to leave the transmission assembly 32 and has not yet fully entered the clip 8, the track push plate assembly 33 pushes the circuit board away from the transmission assembly 32 by rotating the block 333 and allows the circuit board to fully enter the clip 8;

[0100] 6. The test board lifting assembly 53 drives the clip 8 to move vertically to fill the clip 8 with circuit boards;

[0101] 7. The test board telescopic assembly 52 drives the test board clamping assembly 51 to extend horizontally and place the clip 8 filled with circuit boards into the feeding end of the test board receiving mechanism 7. The test board receiving mechanism 7 then delivers the clip 8 horizontally.

[0102] 2. When the circuit board is good:

[0103] 1. Move the circuit board on the working platform 2 to the pre-discharge track conveying mechanism 3 through the discharging grabbing arm 4;

[0104] 2. The test board lifting assembly 53 drives the post-discharge track conveying mechanism 9 to move vertically, so that the post-discharge track conveying mechanism 9 is flush with the pre-discharge track conveying mechanism 3, and the good boards are conveyed from the pre-discharge track conveying mechanism 3 to the post-discharge track conveying mechanism 9;

[0105] 3. The good and empty magazine conveying mechanism 20 conveys the empty magazine 8 in the horizontal direction toward the good magazine clamping and lifting mechanism 10;

[0106] 4. The good plate telescopic assembly drives the good plate clamping assembly to move horizontally, and the good plate clamping assembly clamps the empty magazine 8 from the good plate empty magazine conveying mechanism 20 and then retreats;

[0107] 5. After discharging, the track conveying mechanism 9 conveys the good board to the clip 8 clamped by the good board clamping assembly;

[0108] 6. The good plate lifting assembly drives the magazine 8 to move vertically, filling the magazine 8 with good plates;

[0109] 7. The good plate telescopic assembly drives the good plate clamping assembly to move laterally, places the magazine 8 filled with good plates on the good plate receiving mechanism 30, and outputs it laterally.

[0110] 3. When the circuit board is an NG board: the circuit board is moved from the working platform 2 to the NG board placement mechanism 40 through the unloading and grabbing arm 4.

[0111] 4. When the circuit boards are allowed to be stacked and stored, the circuit boards are moved from the working platform 2 to the stacking and receiving placement mechanism 50 by the unloading and grabbing arm 4 .

[0112] This completes the working process of the clip-type automatic unloading device of the preferred embodiment.

[0113] The clip-type automatic unloading device of the present invention moves the circuit board on the working platform to the pre-discharge track conveying mechanism through the discharging grab plate arm, and conveys the empty clip in the horizontal direction and in the direction close to the clip clamping lifting mechanism of the test clip through the empty clip conveying mechanism of the test board. The telescopic assembly of the test board drives the clamping assembly of the test board to extend in the horizontal direction to the discharging end of the empty clip conveying mechanism of the test board and clamps the empty clip. Then the telescopic assembly of the test board drives the clamping assembly of the test board to retract in the horizontal direction, and the pre-discharge track conveying mechanism conveys the circuit board to the clip clamped by the clamping assembly of the test board. The lifting assembly of the test board drives the clip to move vertically to fill the clip with circuit boards. The telescopic assembly of the test board drives the clamping assembly of the test board to extend in the horizontal direction and places the clip filled with circuit boards on the feeding end of the material receiving mechanism of the test board, and the material receiving mechanism of the test board outputs the clip in the horizontal direction. The magazine-type automatic unloading device of the present invention can automatically input an empty magazine, and automatically load the circuit board on the working platform into the magazine and then output it without manual assistance, and has high unloading efficiency.
