[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0032] like Figure 1-Figure 16As shown, the present invention provides a copper guide bar array machine, including an operating table 1, a conveying frame 30 is provided at the upper end of the operating table 1, a silk screen plate 13 is placed on the conveying frame 30, a vibrating screen plate 8 is also provided on the operating table 1, and a rotatable worm 5 is provided on both sides of the vibrating screen plate 8, and when the worm 5 rotates, a structure in which the vibrating screen plate 8 swings back and forth and oscillates back and forth; a loading and unloading device matched with the silk screen plate 13 is provided on the conveying frame 30, and the loading and unloading device includes a bracket 32, and a plurality of evenly distributed telescopic clamping rods 39 are provided on the bracket 32, and when the bracket 32 ​​moves upward, a structure in which the plurality of telescopic clamping rods 39 move inward and then outward can be formed.

[0033] like Figure 1-Figure 6 As shown, a plurality of supporting legs 2 are provided at the bottom of the operating table 1, and the supporting legs 2 and the operating table 1 can support, install and fix the entire device; a plurality of rotatable rollers are respectively provided at the inner ends of the conveying frame 30, and when the screen printing plate 13 is placed on the conveying frame 30, the screen printing plate 13 can be driven to reach the specified position when the rollers rotate; when the screen printing plate 13 reaches the position directly above the bracket 32, through the bracket 32 ​​that can move up and down, the screen printing plate 13 can be driven to move upward when the bracket 32 ​​moves upward, and the corresponding telescopic clamping rod 39 can move inward, and the screen printing plate 13 is clamped and fixed after the center calibration is performed, and a card slot 14 that matches the screen printing plate 13 is opened in the middle of the vibrating screen plate 8, and when the bracket 32 ​​continues to move upward, the corresponding telescopic clamping rod 39 can move outward and no longer clamp and fix the screen printing plate 13, and the screen printing plate 13 can be pushed and squeezed by the bracket 32. Push it into the vibrating sieve plate 8, that is, the card slot 14, and then set a rotatable worm 5. When the worm 5 rotates, it can drive the vibrating sieve plate 8 to swing back and forth and oscillate back and forth. A plurality of grains are placed in the vibrating sieve plate 8. When the vibrating sieve plate 8 swings back and forth, the grains can flow up and down. A plurality of silk screen grooves for loading grains are opened on the silk screen plate 13, so that the grains slide into the corresponding silk screen grooves. When the vibrating sieve plate 8 oscillates back and forth, the loading efficiency can be further improved, and more grains can be loaded into the silk screen grooves faster. When the vibrating sieve plate 8 oscillates back and forth, the silk screen plate 13 completes the grain loading, and the bracket 32 ​​that moves up and down can make the silk screen plate 13 be placed on the conveyor frame 30 again, and arrive at the next station under the transportation of the conveyor frame 30. It can be used in conjunction with the production line to lay grains on the silk screen plate 13, and it can automatically load and unload materials instead of manual operation, reduce costs, and improve productivity.

[0034] The first motor 3 is fixedly connected to the left and right sides of the upper end surface of the operating table 1, and the output ends of the first motor 3 are fixedly connected to the worm gear 4, and the worm 5 is meshed with the corresponding lower end of the worm gear 4. The inner end surfaces of the two worm gears 5 are fixedly connected to the driving shaft 6, and the outer surfaces of the driving shaft 6 are slidably connected to the pendulum seats 7, and the vibrating screen plate 8 is fixedly connected to the upper end surfaces of the two pendulum seats 7.

[0035] like Figure 3 As shown, the function of the first motor 3 is to provide rotational force for the worm wheel 4 and the worm 5. The motor is of prior art and will not be described in detail. The outer surfaces of the worm 5 and the driving shaft 6 are respectively rotatably connected with bearing seats, and the bottom ends of the bearing seats are respectively fixed to the upper end surface of the operating table 1, and the limiting worm 5 and the driving shaft 6 can only rotate. When the first motor 3 is started, it can drive the corresponding worm wheel 4 to rotate. When the worm wheel 4 rotates, it can also drive the worm 5 and the driving shaft 6 to rotate through the engagement with the worm 5. The driving shaft 6 and the pendulum seat 7 are splined, that is, the pendulum seat 7 can slide left and right on the outer surface of the driving shaft 6, and when the driving shaft 6 rotates, it can drive the pendulum seat 7 to swing back and forth. Therefore, when the driving shaft 6 rotates, it can drive the pendulum seat 7 to swing back and forth, that is, the corresponding vibrating sieve plate 8 swings back and forth, and the pendulum seat 7 can slide left and right on the outer surface of the driving shaft 6, that is, it does not affect the left and right movement of the pendulum seat 7 and the vibrating sieve plate 8.

[0036] An extension pin 9 is fixedly connected to the lower end of the outer surface of the swing seat 7, and arc-shaped track plates 10 are fixedly connected to the left and right sides of the upper end surface of the operating table 1. The arc-shaped horizontal groove 11 and the arc-shaped wave groove 12 that match the extension pin 9 are respectively opened on the arc-shaped track plate 10.

[0037] like Figure 4 As shown, when the swing seat 7 swings back and forth, the extension pin 9 can be driven to move in a circle. When the extension pin 9 moves in a circle, through the engagement with the arc-shaped transverse groove 11, the extension pin 9 can move in a circle in the middle position, that is, the corresponding swing seat 7 and the vibrating sieve plate 8 will not move left or right when they swing back and forth. When the extension pin 9 moves into the corresponding arc-shaped wave groove 12, the extension pin 9 can oscillate back and forth left and right under the engagement of the arc-shaped wave groove 12, that is, the corresponding swing seat 7 and the vibrating sieve plate 8 can oscillate back and forth left and right when they swing back and forth. Through the cooperation of the extension pin 9, the arc-shaped wave groove 12 and the arc-shaped transverse groove 11, the vibrating sieve plate 8 can not oscillate back and forth left and right when it swings in the middle position. When the vibrating sieve plate 8 swings forward or backward to the specified position and continues to swing, that is, when the extension pin 9 is engaged with the arc-shaped wave groove 12, the vibrating sieve plate 8 can oscillate back and forth left and right while swinging forward or backward.

[0038] Four evenly distributed telescopic rods 31 are fixedly connected to the middle of the upper end surface of the operating table 1, and a bracket 32 ​​is fixedly connected to the telescopic ends of the four telescopic rods 31. A rotatable first disc 34 is provided at the lower end of the bracket 32, and four evenly distributed first connecting rods 36 are hinged at the non-center of the lower end surface of the first disc 34. The telescopic clamping rods 39 are respectively slidably connected to the inner walls of the bracket 32, and the telescopic clamping rods 39 are respectively hinged to the corresponding first connecting rods 36.

[0039] like Figure 10-13 As shown, the telescopic rod 31 can be extended and retracted up and down, thereby driving the bracket 32 ​​to move up and down. The telescopic rod 31 is a prior art and will not be described in detail. The installation and shape of the telescopic clamping rod 39 are as shown in FIG. Fig.12 or Fig.13 As shown, the telescopic clamp rod 39 can be slidably connected to the bracket 32 ​​forward and backward or left and right, and a connecting rod 37 is fixed to the lower end of the left and right telescopic clamp rods 39. The connecting rod 37 is hinged to the corresponding first connecting rod 36, which is equivalent to the telescopic clamp rod 39 being hinged to the first connecting rod 36. That is, when the first disk 34 rotates, it can drive the inner end of the first connecting rod 36 to move in a circle, and the outer end of the first connecting rod 36 will drive the corresponding telescopic clamp rod 39 to move inward or outward, that is, the telescopic clamp rod 39 can clamp or loosen the silk screen plate 13.

[0040] The telescopic clamp rod 39 includes an outer tube 40 and an inner rod 42. The outer tube 40 is slidably connected to the bracket 32, and the inner rod 42 is slidably connected to the inner wall of the outer tube 40. The inner wall at the bottom end of the outer tube 40 is fixedly connected with a third spring 41 that matches the inner rod 42.

[0041] like Fig.14 As shown, the inner rod 42 can slide up and down on the inner wall of the outer cylinder 40, and the third spring 41 always has an upward driving force on the inner rod 42, so that the inner rod 42 is in the topmost state under normal conditions. When the bracket 32 ​​pushes the screen printing plate 13 upward, that is, when the bracket 32 ​​moves upward until it is about to contact the vibrating sieve plate 8, the inner rod 42 can contact the lower end surface of the vibrating sieve plate 8. When the bracket 32 ​​continues to move upward, the inner rod 42 can contact the lower end surface of the vibrating sieve plate 8. Under the obstruction of the vibrating sieve plate 8, it can move downward into the inner wall of the outer cylinder 40 and compress the third spring 41. Through the telescopic clamping rod 39, the screen printing plate 13 can be calibrated, clamped and fixed without affecting the bracket 32 ​​pushing the screen printing plate 13 upward.

[0042] An extension shaft 33 rotatably connected to the bracket 32 ​​is fixedly connected to the inner wall at the center of the first disc 34, a first sliding pin 35 is fixedly connected to the inner wall at the lower end of the extension shaft 33, a long cylinder 43 is fixedly connected to the inner wall in the middle of the operating table 1, and a lower vertical groove 44, a lower inclined groove 45, a middle vertical groove 46, an upper inclined groove 47 and an upper vertical groove 48 matching with the first sliding pin 35 are respectively formed on the inner walls at the front and rear ends of the long cylinder 43.

[0043] like Figure 13-Figure 15 As shown, the extension shaft 33 and the first disc 34 are fixedly connected, and when the extension shaft 33 rotates, the first disc 34 can be driven to rotate; the installation and shape of the first sliding pin 35 and the long cylinder 43 are as shown in FIG. Fig.15As shown, when the bracket 32, the extension shaft 33, the first sliding pin 35, etc. move upward, the first sliding pin 35 can move vertically upward by engaging with the lower vertical slot 44. When the first sliding pin 35 continues to move upward and enters the inner wall of the lower inclined slot 45, the first sliding pin 35 will move upward while rotating in the positive direction, that is, the corresponding extension shaft 33 and the first disc 34 will rotate in the positive direction, and the telescopic clamping rod 39 can move synchronously inward to clamp and fix the screen printing plate 13. When the first sliding pin 35 continues to move upward and enters the inner wall of the middle vertical slot 46, the first sliding pin 35 will move vertically upward again. When the first sliding pin 35 moves upward to enter the inner wall of the upper inclined slot 47, the first sliding pin 35 will rotate in the opposite direction while moving upward. When the first slide pin 35 is moved upward, the corresponding first disc 34 will reverse and reset, and the telescopic clamping rod 39 can move outward and no longer clamp the screen printing plate 13. When the first sliding pin 35 continues to move upward and enters the inner wall of the upper vertical groove 48, the first sliding pin 35 can rotate to the initial state, that is, the first disc 34 is reversed and reset to the initial state, and can move vertically upward under the limit of the upper vertical groove 48; through the cooperation of the first sliding pin 35 and the long cylinder 43, when the bracket 32 ​​moves upward from the lower end to load the material, the first sliding pin 35 is engaged with the lower vertical groove 44, and the telescopic clamping rod 39 will not move. When the bracket 32 ​​moves upward to hold up the screen printing plate 13, the first sliding pin 35 enters the inner wall of the lower inclined groove 45, that is, the bracket 32 ​​moves upward When it moves to the specified position, the telescopic clamping rod 39 starts to work and can calibrate the center of the screen printing plate 13. When the bracket 32 ​​continues to move upward to make the first sliding pin 35 enter the inner wall of the middle vertical groove 46, the telescopic clamping rod 39 can move inward to the topmost position, that is, clamp and fix the screen printing plate 13, and the screen printing plate 13 will be directly below the slot 14. When the bracket 32 ​​continues to move upward to make the first sliding pin 35 enter the inner wall of the upper inclined groove 47, the telescopic clamping rod 39 can move outward, that is, no longer clamp and fix the screen printing plate 13. At this time, the bracket 32 ​​continues to move upward to enable the screen printing plate 13 to be inserted into the inner wall of the slot 14, and the first sliding pin 35 will enter the inner wall of the upper vertical groove 48 again. The corresponding telescopic clamp The rod 39 can move to the outermost end; when the bracket 32 ​​moves downward from the upper end to pick up materials, the screen printing plate 13 will fall onto the bracket 32 ​​under the action of gravity after the baffle 15 moves outward, and the first sliding pin 35 can be driven to move downward when the bracket 32 ​​moves downward, and under the engagement of the first sliding pin 35 with the upper vertical groove 48, the upper inclined groove 47, the middle vertical groove 46, the lower inclined groove 45, and the lower vertical groove 44, the telescopic clamping rod 39 can calibrate the screen printing plate 13 again and clamp it to fix it. When the bracket 32, the first sliding pin 35, etc. move downward to the bottom, the telescopic clamping rod 39 can move outward and reset, that is, it no longer clamps the screen printing plate 13, and the screen printing plate 13 can be calibrated and fixed again and then accurately placed on the conveying rack 30.

[0044] The lower end surface of the vibrating sieve plate 8 is provided with a plurality of blocking devices, which respectively include two side plates 17, and the inner sides of the two side plates 17 are respectively provided with square sliders 18 that can move up and down, and the inner walls of the square sliders 18 are respectively provided with locking mechanisms. When the square sliders 18 move upward or downward to the top end, the locking mechanisms can lock the position of the square sliders 18, and short connecting rods 16 are respectively hinged on the square sliders 18. The lower end surface of the vibrating sieve plate 8 is slidably connected with a plurality of baffles 15 that cooperate with the silk-screen plate 13, and the baffles 15 are respectively hinged on the corresponding short connecting rods 16.

[0045] like Figure 6-Figure 8 As shown, the blocking device can block and fix the screen printing plate 13, so that the screen printing plate 13 is fixed to the inner wall of the slot 14, the square slider 18 can be slid up and down and connected to the inner walls of the two side plates 17, and the baffle 15 can move forward and backward on the lower end surface of the vibrating screen plate 8. Through the hinge connection between the short connecting rod 16, the square slider 18 and the baffle 15, when the square slider 18 moves downward, the baffle 15 can be driven to move inward. When the baffle 15 moves inward to the top position, the screen printing plate 13 can be blocked to prevent the screen printing plate 13 from moving downward and disengaging from the slot 14. When the square slider 18 moves upward, the baffle 15 can be driven to move inward. When the baffle 15 is moved outward and out of contact with the screen printing plate 13, the baffle 15 no longer blocks the screen printing plate 13, and the screen printing plate 13 can move downward under the action of gravity to disengage from the inner wall of the slot 14; through the provided locking mechanism, when the square slider 18 moves upward to the top or downward to the top position, the locking mechanism can fix the position of the square slider 18, that is, the position of the baffle 15 can be fixed, even if the baffle 15 is at the innermost end, it can stably support the screen printing plate 13, and when the baffle 15 is at the outermost end, it can disengage from the screen printing plate 13, and will not hinder the loading and unloading of the bracket 32.

[0046] The locking mechanism includes a locking plate 27 fixed to the side plate 17, a cylindrical cam 19 fixed to the inner walls of the upper and lower ends of the square slider 18, an inner core 20 is provided on the upper end of the square slider 18, a movable pin 21 matched with the cylindrical cam 19 is fixed to the outer surface of the inner core 20, an extension rod 26 is fixed to the upper end surface of the inner core 20, a trapezoidal locking block 28 is fixed to the upper end surface of the extension rod 26, a rectangular hole 29 matched with the trapezoidal locking block 28 is opened on the locking plate 27, a connecting pad 22 is rotatably connected to the lower end surface of the inner core 20, a first spring 23 matched with the connecting pad 22 is fixed to the inner wall of the bottom end of the square slider 18, a second spring 25 is sleeved on the outer surface of the extension rod 26, one end of the second spring 25 is fixed to the corresponding locking plate 27, and the other end of the second spring 25 is fixed to the corresponding square slider 18.

[0047] like Figure 8-Figure 9As shown, the lock plate 27 is fixedly connected to the inner end surfaces of the two side plates 17, and the inner core 20 can move up and down and rotate on the inner wall of the square slider 18. The first spring 23 always has an upward driving force on the connecting pad 22 and the inner core 20, so that the inner core 20 and the first sliding pin 35 are at the topmost position of the square slider 18 under normal conditions. The inner core 20 does not affect the connection with the first spring 23 when rotating through the connecting pad 22 and the inner core 20. The first spring 23 always pushes the inner core 20 with an upward driving force, and the two do not affect each other; the second spring 25 always has a downward driving force on the square slider 18, so that the square slider 18 is at the bottommost position under normal conditions; the installation and shape of the trapezoidal lock block 28, the rectangular hole 29, and the lock plate 27 are as shown in FIG. Fig. 9As shown, the cylindrical cam 19 includes a first cam and a second cam. The installation and shape of the first cam, the second cam and the movable pin 21 are as shown in the figure. When the trapezoidal locking block 28 is parallel to the rectangular hole 29, the trapezoidal locking block 28 can move up and down through the rectangular hole 29. When the trapezoidal locking block 28 is perpendicular to the rectangular hole 29, the rectangular hole 29 can block the trapezoidal locking block 28 from moving downward. When the square slider 18 is in the locked state at the uppermost position, that is, the corresponding baffle 15 is at the innermost end, that is, the corresponding trapezoidal locking block 28 is at the uppermost position. When the trapezoidal locking block 28 is in contact with the lower end surface of the vibrating sieve plate 8, that is, the trapezoidal locking block 28 is in the upper end position of the locking plate 27 and is in a vertical state with the rectangular hole 29, when the square slider 18 is driven to move upward, the corresponding first cam, second cam and first spring 23 will be driven to move upward. Since the trapezoidal locking block 28 has moved to the top position and is in contact with the vibrating sieve plate 8, the trapezoidal locking block 28, the extension rod 26, the inner circular core 20, the live pin 21 and the like will not move upward under the obstruction of the vibrating sieve plate 8. When the square slider 18 moves upward When the first cam contacts the live pin 21, the live pin 21 can be rotated under the meshing of the first cam and the live pin 21, that is, the corresponding inner core 20, the extension rod 26, and the trapezoidal locking block 28 rotate. When the square slider 18 moves upward to the top, the inner core 20, the extension rod 26, and the trapezoidal locking block 28 can rotate 45 degrees under the meshing of the live pin 21 and the first cam. When the square slider 18 moves downward to reset under the elastic force of the second spring 25, the second cam can contact and mesh with the live pin 21. When the square slider 18 continues to move downward, the inner core 20, the extension rod 26, and the trapezoidal locking block 28 can rotate 45 degrees. When the movable pin 21 is reset, the movable pin 21, the trapezoidal locking block 28, etc. can be rotated 45 degrees again under the meshing of the second cam and the movable pin 21. After rotating two 45 degrees, the trapezoidal locking block 28 can be in a parallel state with the rectangular hole 29, that is, the trapezoidal locking block 28 can pass through the rectangular hole 29 and move downward, that is, the square slider 18 can move downward to the bottom position, and when the slider 18 is at the bottom position under the elastic force of the second spring 25, the square slider 18 can be in a stable state, that is, the corresponding baffle 15 is in a stable state at the outermost end;When the square slider 18 moves upward again, the trapezoidal locking block 28 and the rectangular hole 29 are in a normal state, that is, the trapezoidal locking block 28 can pass through the rectangular hole 29. When the square slider 18 moves upward so that the trapezoidal locking block 28 passes through the rectangular hole 29 and contacts the lower end surface of the vibrating screen plate 8, the square slider 18 continues to move upward and the corresponding trapezoidal locking block 28, the inner circular core 20, the live pin 21, etc. no longer move upward, that is, the first spring 23 will be compressed, and the live pin 21 will engage with the first cam again. Under the engagement of the first cam, the live pin 21 can be rotated 45 degrees, that is, the trapezoidal locking block 28 rotates 45 degrees. At this time, the trapezoidal locking block 28 is misaligned with the rectangular hole 29 and cannot pass through the rectangular hole 29. When the square slider 18 is in the second When the block 21 is reset by moving downward under the elastic force of the spring 25, the second cam is engaged with the live pin 21 again under the elastic force of the first spring 23. The live pin 21 and the trapezoidal locking block 28 can be rotated 45 degrees again under the engagement of the second cam and the live pin 21, that is, the trapezoidal locking block 28 and the rectangular hole 29 are vertical again, that is, the square slider 18 is in the topmost position locked state, that is, the corresponding baffle 15 is in the innermost stable state, that is, through the provided locking mechanism, each time the square slider 18 is pushed upward, the corresponding square slider 18 can be in the bottommost position locked state or in the topmost position locked state, that is, the corresponding baffle 15 is in the outermost stable state or the innermost stable state. ;

[0048] The inner wall of the bracket 32 ​​is slidably connected with four evenly distributed first guide rods 50, the upper end surfaces of the four first guide rods 50 are fixedly connected with an I-shaped plate 49, and the outer surfaces of the first guide rods 50 are respectively sleeved with fourth springs 51 that match the I-shaped plate 49; the lower end surfaces of the square slider 18 are respectively fixedly connected with short guide rods 24, and the front and rear sides of the lower end surface of the bracket 32 ​​are respectively fixedly connected with top plates 52 that match the short guide rods 24.

[0049] like Figure 8 , Fig.11 , Fig.16As shown, the first guide rod 50 can slide up and down on the inner wall of the bracket 32, that is, the limit I-plate 49 can only move up and down on the upper end of the bracket 32, and the lower end surface of the first guide rod 50 is respectively fixed with an anti-slip pad, the function of the anti-slip pad is to prevent the first guide rod 50 from being separated from the bracket 32, and the fourth spring 51 always has an upward driving force on the I-plate 49, so that the I-plate 49 is in the topmost position under normal conditions. Through the cooperation of the short guide rod 24 and the top plate 52, when the bracket 32 ​​moves upward to the top position, the top plate 52 can push the short guide rod 24 and the square slider 18 to move upward once. When the top plate 52 moves downward and disengages from the short guide rod 24, the square slide block 18 can move downward and reset under the elastic force of the second spring 25, that is, when the bracket 32 ​​pushes the square slide block 18 to move upward once, the square slide block 18 can be in the lowest position or the highest position locked state, that is, the corresponding baffle 15 is in the innermost or outermost stable state; when the bracket 32 ​​moves upward for loading, it can drive the I-shaped plate 49 to move upward, and the I-shaped plate 49 can lift the screen printing plate 13 to move upward. When the bracket 32 ​​moves upward to make the screen printing plate 13 enter the inner wall of the slot 14, the bracket 32 ​​continues to move upward. When the bracket 32 ​​moves downward, the fourth spring 51 can be compressed, and the top plate 52 can contact the short guide rod 24. When the bracket 32, the top plate 52, etc. continue to move upward, the square slider 18 can move upward. When the square slider 18 moves upward to the locked state, the baffle 15 is at the innermost end and is stable, that is, the baffle 15 can prevent the screen printing plate 13 from disengaging from the slot 14; at this time, after the bracket 32 ​​moves downward and resets, the corresponding vibrating screen plate 8 can work normally to lay grains on the screen printing plate 13. When the screen printing plate 13 needs to unload after laying the grains, the top plate 52 can be squeezed again by driving the bracket 32 ​​upward again. The short guide rod 24 moves upward, that is, the square slider 18 moves upward once. After the square slider 18 moves upward once, it moves downward to reset, that is, the bracket 32 ​​moves downward to reset. At this time, the square slider 18 can be in the locked state at the lowermost position, that is, the corresponding baffle 15 can move outward to the top end and be in a stable state, that is, the baffle 15 no longer blocks the screen printing plate 13. At this time, the screen printing plate 13 will fall onto the I-plate 49 and the bracket 32 ​​under the action of gravity, that is, when the bracket 32 ​​moves downward to the top end, the screen printing plate 13 can be placed on the conveying rack 30, and the screen printing plate 13 can flow to the next station under the transportation of the conveying rack 30.

[0050] When the present invention is in use, when the screen printing plate 13 is placed on the conveying rack 30, the screen printing plate 13 can be driven to the specified position when the roller rotates; when the screen printing plate 13 reaches the position directly above the bracket 32, the bracket 32 ​​can be moved up and down, and the bracket 32 ​​can drive the screen printing plate 13 to move upward when it moves upward, and the corresponding telescopic clamping rod 39 can move inward, and the screen printing plate 13 is clamped and fixed after the center calibration is performed. When the bracket 32 ​​continues to move upward, the corresponding telescopic clamping rod 39 can move outward and no longer clamp and fix the screen printing plate 13. Under the pushing and squeezing of the bracket 32, the screen printing plate 13 can be pushed into the vibrating screen plate 8, that is, the card slot 14, and then by setting a rotatable worm 5 When the worm 5 rotates, it can drive the vibrating screen plate 8 to swing back and forth and oscillate back and forth. A plurality of crystal grains are placed in the vibrating screen plate 8. When the vibrating screen plate 8 swings back and forth, the crystal grains can flow up and down, and the crystal grains can slide into the corresponding screen printing grooves. When the vibrating screen plate 8 oscillates back and forth, the loading efficiency can be further improved, and more crystal grains can be loaded into the screen printing grooves faster. After the screen printing plate 13 completes the crystal grain loading, the screen printing plate 13 can be placed on the conveying rack 30 again through the up and down moving bracket 32, and arrive at the next workstation under the transportation of the conveying rack 30. It can be used in conjunction with the production line to lay crystal grains on the screen printing plate 13, and can automatically load and unload materials instead of manual operation, reduce costs, and improve productivity.
