Description

Technical Field

[0001] The present invention relates to the technical field of packaging detection, and in particular to a high-precision automatic detection device and method for UV curing adhesive packaging quality. Background Art

[0002] The prior art discloses a high-precision UV curing glue packaging quality automatic detection device and method with application number CN202111427230.2, which includes a frame, one side of the frame is provided with a loading area, and the other side is provided with a receiving area, one side of the loading area is connected to a glue dripping device, and the frame between the loading area and the receiving area is respectively provided with a camera detection area, a glue height measurement area and a material pulling mechanism. This invention has the function of online automatic detection of glue height, and has fast speed and high precision. The equipment is used to replace manpower, saving labor costs; However, in the actual detection process, the object to be detected is directly placed on the conveyor belt, so that the object to be detected passes through the camera detection area. The overall operation is simple, but the object to be detected is in a fixed state relative to the conveyor belt. When the camera is used for detection, the camera cannot completely cover the area of ​​the UV curing glue, and there are certain blind spots for shooting, which leads to the inability to complete the detection operation of the object to be detected well. In addition, since the object to be detected is always in a moving state, when the camera is used to detect the moving object, if the object moves faster, the detection effect of the camera will be greatly reduced. If the object moves slower, the overall detection speed will be slower, thereby reducing the overall work efficiency. In addition, in the actual detection process, only using the camera for detection cannot detect the connection status of the object after UV curing glue encapsulation. Therefore, a high-precision UV curing glue encapsulation quality automatic detection device and method are provided. Summary of the invention

DETAILED DESCRIPTION

[0015] See also Figure 1-Figure 11 A high-precision UV curing glue packaging quality automatic detection equipment includes a workbench 1, a bracket 2 is installed on the upper side of the workbench 1, a plurality of baffles 4 are symmetrically fixedly installed in the bracket 2, a plurality of cameras 3 are evenly fixedly installed on the lower side of the bracket 2, a double-axis motor 5 is fixedly installed on the outer side of the workbench 1, and a rotating shaft 6 is fixedly installed at both output ends of the double-axis motor 5, a plurality of transmission rods 7 are rotatably installed in the bracket 2, and a conveyor belt 8 is commonly sleeved on the outer sides of the plurality of transmission rods 7, one of the rotating shafts 6 is fixedly passed through one of the transmission rods 7, First, when it is necessary to perform quality inspection on objects packaged with UV curing adhesive, the objects to be inspected are placed on the conveyor belt 8, and the dual-axis motor 5 is started. The dual-axis motor 5 drives the transmission rod 7 to rotate through the rotating shaft 6, and the transmission rod 7 drives the conveyor belt 8 and the objects placed on the conveyor belt 8 to move. During this process, the objects will pass through the area photographed by the camera 3, and the camera 3 will be used to photograph the objects, and the data obtained by the photography will be transmitted to the control center (such as a computer) for comparison and analysis, and then the packaging quality of the objects will be obtained. Then, in the process of the objects following the movement of the conveyor belt 8, under the limiting effect of the baffle 4, the objects can be effectively prevented from falling from the conveyor belt 8. The above are all existing technologies and no unnecessary elaboration will be made. A moving assembly is installed in the bracket 2, and the moving assembly includes a plurality of trapezoidal plates 9. The plurality of trapezoidal plates 9 are divided into two groups, and each group of trapezoidal plates 9 is symmetrically distributed on both sides of the conveyor belt 8. The plurality of trapezoidal plates 9 and the baffles 4 are staggered. A square groove 10 is opened on the side wall of each trapezoidal plate 9, and a second connecting rod 14 is slidably connected in the square groove 10. A first spring 11 is fixedly connected between the second connecting rod 14 and the square groove 10. A control assembly for controlling the movement of the second connecting rod 14 is installed in the bracket 2, and the control assembly includes a plurality of first connecting plates 12 fixedly installed in the bracket 2. The number and position of the plurality of first connecting plates 12 are opposite to the trapezoidal plate 9, the side wall of each first connecting plate 12 is rotatably connected to a first connecting rod 13, two adjacent first connecting rods 13 are connected by a first pulley assembly 15, and one of the first connecting rods 13 and the rotating shaft 6 are connected by a second pulley assembly 16, the outer side of each first connecting rod 13 is fixedly connected to a reciprocating screw rod 17, the outer side of the reciprocating screw rod 17 is threadedly connected to a reciprocating block 18, the bracket 2 of the reciprocating block 18 is slidably connected, and the reciprocating block 18 is fixedly connected to the second connecting rod 14; First, a plurality of slide grooves are opened on the outer side of the bracket 2, and the reciprocating block 18 is located between two adjacent slide grooves, and a slide rod is slidably connected in each slide groove, and the slide rod and the reciprocating block 18 are fixedly connected. Secondly, in the process of the object following the movement of the conveyor belt 8, under the transmission action of the first pulley assembly 15 and the second pulley assembly 16, the rotating shaft 6 will drive all the first connecting rods 13 to rotate, and the first connecting rod 13 will drive the reciprocating screw rod 17 to rotate. Since the reciprocating screw rod 17 and the reciprocating block 18 are threadedly connected, and the reciprocating block 18 is slidably connected to the bracket 2 through the slide groove and the slide rod, the rotating reciprocating screw rod 17 will drive the reciprocating block 18 to move back and forth, and the reciprocating block 18 drives the trapezoidal plate 9 to move back and forth through the second connecting rod 14 and the first spring 11. In the process of the trapezoidal plate 9 moving back and forth, if the object to be detected at this time When the object is located between the two trapezoidal plates 9, the object will abut against the side walls of the two trapezoidal plates 9 and then move to the upper side of the two trapezoidal plates 9, so that the object to be detected and the conveyor belt 8 are disconnected, thereby causing the object to be detected to move upward relative to the workbench 1. When the two trapezoidal plates 9 abut against each other, the two second connecting rods 14 will continue to move a distance toward each other under the action of the reciprocating block 18. At this time, the object to be detected stays on the upper side of the two trapezoidal plates 9, forming a brief relative stillness, thereby improving the shooting effect of the camera 3 on the object to be detected. And unlike when the object to be detected is placed on the conveyor belt 8, after the object to be detected and the trapezoidal plates 9 abut against each other, the load-bearing surface of the object to be detected may change, which may cause the object to be detected to move, thereby further improving the shooting effect of the object to be detected; In the above process, if the appearance of the object to be detected is a regular polygon or an approximate regular polygon, and the bottom of the object to be detected is a plane, after the trapezoidal plate 9 and the object to be detected are abutted, the load-bearing surface of the object to be detected will not change. If the appearance of the object to be detected is strange, after the trapezoidal plate 9 and the object to be detected are abutted, the trapezoidal plate will abut against other surfaces of the object to be detected, thereby causing the object to be detected to move relative to the trapezoidal plate 9, thereby causing the object to be detected to move.

[0016] A shaking assembly is installed on the outer side of the trapezoidal plate 9, and the shaking assembly includes a plurality of rotating cylinders 19. A plurality of rotating grooves 20 are evenly opened on the side wall of each trapezoidal plate 9, and a rotating rod 21 is rotatably installed in each rotating groove 20. The number and position of the plurality of rotating rods 21 are opposite to the rotating cylinder 19. A control groove 22 is also opened on the side wall of each trapezoidal plate 9. The square groove 10 is connected to the rotating groove 20 through the control groove 22. A plurality of third connecting rods 23 are rotatably installed in the control groove 22. The plurality of third connecting rods 23 and the rotating rod 21 are staggered. The outer side of each third connecting rod 23 is fixedly connected to a first gear 24. A first torsion spring 34 is fixedly connected between the first gear 24 and the control slot 22, a second gear 25 is fixedly connected to the outer side of each rotating rod 21, and the second gear 25 is meshed with the first gear 24, a fourth connecting rod 26 is fixedly connected to the outer side of one rotating rod 21, a swing cylinder 27 is fixedly connected to the outer side of the fourth connecting rod 26, and a third connecting plate 28 is fixedly connected to the outer side of the second connecting rod 14, and the outer surfaces of the swing cylinder 27 and the third connecting plate 28 are both smooth, so as to reduce the friction between the swing cylinder 27 and the third connecting plate 28 after the swing cylinder 27 and the third connecting plate 28 abut against each other; First, in the process of the second connecting rod 14 driving the trapezoidal plate 9 to move, when the two trapezoidal plates 9 have not yet abutted against each other, although the two trapezoidal plates 9 will move relative to the second connecting rod 14 under the action of the object to be detected, that is, the first spring 11 will be compressed, but the third connecting plate 28 will not abut against the swing tube 27. After the two trapezoidal plates 9 abut against each other, the second connecting rod 14 will further move relative to the trapezoidal plate 9, thereby causing the third connecting plate 28 and the swing tube 27 to abut against each other (the structure and principle of the above phenomenon are described below). When the third connecting plate 28 and the swing tube 27 abut against each other, due to the special shape of the third connecting plate 28 (the shape of the third connecting plate 28 is as shown in FIG. 1 ), the third connecting plate 28 and the swing tube 27 abut against each other. Figure 8 As shown in the figure, when the third connecting plate 28 and the swing tube 27 abut against each other, due to the abutment between the side walls of the swing tube 27 and the third connecting plate 28, the swing tube 27 and the rotating rod 21 fixedly connected thereto will rotate under the obstruction of the third connecting plate 28, and the rotating rod 21 drives all other rotating rods 21 to rotate through the first gear 24 and the second gear 25, and the first gear 24 applies a force to the first torsion spring 34, causing the first torsion spring 34 to deform, and the rotating rod 21 drives the rotating tube 19 to rotate, and the rotating tube 19 drives the object to be detected to move, thereby causing the object to be detected to move relative to the trapezoidal plate 9, and then causing the object to be detected to move relative to the camera 3, and finally enabling the camera 3 to detect different angles of the object to be detected, thereby expanding the detection range of the camera 3 for the object to be detected, and combining with the attached Figure 8 Due to the special shape of the third connecting plate 28, when the third connecting plate 28 continues to move rightward, the movement direction of the pendulum tube 27 is rotation-reset-rotation-reset.

[0017] A limiting assembly is installed in the trapezoidal plate 9, and the limiting assembly includes a limiting groove 29 opened on the side wall of the square groove 10, and the side wall of the limiting groove 29 slides through the limiting plate 30, and a second spring 31 is fixedly connected between the limiting plate 30 and the limiting groove 29, and a limiting ball 32 is fixedly connected to the outer side of the limiting plate 30, and a stopper 33 is slidably connected in the limiting groove 29; First, the lower surface of the stopper 33 is inclined, and the inclined surface and the limiting ball 32 are against each other. Secondly, when the two trapezoidal plates 9 have not yet against each other, under the obstruction of the limiting ball 32, a part of the stopper 33 extends into the square groove 10. When the second connecting rod 14 drives the trapezoidal plate 9 to move through the first spring 11, when the trapezoidal plate 9 and the object to be detected are against each other, under the obstruction of the object to be detected, the trapezoidal plate 9 will move relative to the second connecting rod 14, thereby compressing the first spring 11 until the second connecting rod 14 and the stopper 33 are against each other. In this process, since the third connecting plate 28 and the second connecting rod 14 are in a fixed state, the third connecting plate 28 will also move relative to the trapezoidal plate 9, but Under the obstruction of the block 33, the third connecting plate 28 will not abut against the swing tube 27. Then, before the two trapezoidal plates 9 abut against each other, the two limit plates 30 have already abutted against each other. As the trapezoidal plate 9 continues to move, the limit plate 30 will move relative to the trapezoidal plate 9. While the limit plate 30 compresses the second spring 31, it drives the limit ball 32 to move. Since the inclined surface of the block 33 has been abutting against the limit ball 32, the block 33 will move downward under the action of its own gravity, thereby causing the second connecting rod 14 to lose the obstruction of the block 33. At this time, when the two trapezoidal plates 9 are completely abutted against each other, the second connecting rod 14 will move relative to the trapezoidal plate 9, and only then will the third connecting plate 28 abut against the swing tube 27.

[0018] A pressing assembly is installed outside the trapezoidal plate 9, and the pressing assembly includes a fifth connecting rod 38 that slides through the square groove 10, a sixth connecting rod 35 is fixedly connected to the upper side of the fifth connecting rod 38, a plurality of fixed rings 36 are fixedly installed on the outer side of the sixth connecting rod 35, and a plurality of rotating rings 47 are also rotatably installed on the outer side of the sixth connecting rod 35, a torque sensor is installed between the sixth connecting rod 35 and the rotating ring 47, the fixed rings 36 and the rotating rings 47 are staggered, and a second torsion spring 46 is fixedly installed between the fixed rings 36 and the rotating rings 47, a seventh connecting rod 48 is fixedly installed on the outer side of the rotating ring 47, a pressing plate 37 is fixedly installed on the outer side of the seventh connecting rod 48, and the fifth connecting rod 35 is fixedly installed on the outer side of the seventh connecting rod 48. A threaded rod 39 is fixedly connected to the lower side of 8, a threaded ring 40 is threadedly connected to the outer side of the threaded rod 39, the threaded ring 40 is rotatably connected to the square groove 10, a third gear 41 is fixedly connected to the outer side of the threaded ring 40, a third rack 42 is also slidably connected in the square groove 10, the third gear 41 and the third rack 42 are meshed, both ends of the third rack 42 are fixedly connected to a second connecting plate 43, a third spring 44 is fixedly connected between the second connecting plate 43 and the square groove 10, an eighth connecting rod 45 is fixedly connected to the lower side of the third rack 42, and a rubber sleeve is fixedly connected to the outer side of the pressing plate 37, which can better form a pressing effect on the object to be detected and improve the friction of the pressing plate 37; First, the torque sensor is a detector for sensing torsional moments on various rotating or non-rotating mechanical parts. The torque sensor converts the physical change of torque into an accurate electrical signal. In the initial state, the pressing plate 37 and the workbench 1 are in a parallel state. Secondly, in the process of the object to be detected moving along the trapezoidal plate 9, the object to be detected is located at the lower side of the pressing plate 37 and gradually approaches the pressing plate 37. When the object to be detected and the pressing plate 37 are against each other, the pressing plate 37 will drive the rotating ring 47 to rotate through the seventh connecting rod 48. The rotating ring 47 will not only cause the torque sensor to send a corresponding electrical signal, but also cause the second torsion spring 46 to deform. Then, when the two trapezoidal plates 9 are completely against each other (that is, the second connecting rod 14 loses the block 33), the second torsion spring 46 will be deformed. After restriction), when the pendulum cylinder 27 performs a rotation-reset-rotation-reset movement process under the action of the third connecting plate 28, the fourth connecting rod 26 that moves with the pendulum cylinder 27 will resist the eighth connecting rod 45, causing the eighth connecting rod 45 and the second connecting plate 43 to move, and the second connecting plate 43 will cause the third spring 44 fixedly connected thereto to deform, and at the same time the eighth connecting rod 45 drives the third rack 42 to move, the third rack 42 drives the third gear 41 to rotate, and the third gear 41 drives the threaded ring 40 to rotate. Since the threaded ring 40 and the square groove 10 are in a rotationally connected state, and the fifth connecting rod 38 and the square groove 10 on the trapezoidal plate 9 are slidingly connected, the rotating threaded ring 40 will cause the fifth connecting rod 38 to move relative to the trapezoidal plate 9 The fifth connecting rod 38 drives the sixth connecting rod 35 to move, the sixth connecting rod 35 drives the rotating ring 47 and the fixed ring 36 to move, and the rotating ring 47 drives the pressing plate 37 to move through the seventh connecting rod 48. In this case, the pressing plate 37 can be controlled to move downward by controlling the threaded direction of the threaded rod 39 and the threaded ring 40. Therefore, when the swing cylinder 27 performs a rotation-reset-rotation-reset movement process under the action of the third connecting plate 28, the movement trajectory of the pressing plate 37 is downward pressing-reset-downward pressing-reset, so that the force of the pressing plate 37 on the object to be detected can be gradually increased, thereby simulating the pressing operation on the object to be detected after being packaged, and the pressing is intermittent, and will not cause great damage to the object to be detected. In the above working process When the pendulum 27 first abuts against the third connecting plate 28, the third connecting plate 28 causes the pendulum 27 and the rotating rod 21 to rotate around the rotating rod 21. During this process, when the corners of the pendulum 27 and the third connecting plate 28 abut against each other, the rotation angle of the pendulum 27 is the largest. At this time, the force exerted by the pressing plate 37 abutting against the object to be detected on the object to be detected is the largest, until the third connecting plate 28 and the pendulum 27 are disconnected, that is, a "press down-reset" process is completed. During the continuous movement of the third connecting plate 28, when the pendulum 27 abuts against the third connecting plate 28 again, the pendulum 27 will swing again, and finally the pressing plate 37 will continue to perform the "press down-reset-press down-reset" process. During the overall process,The force exerted by the pressing plate 37 on the object to be detected is within a certain range, forming a pressing operation, and the size of the electrical signal emitted by the torque sensor is also within a certain range. During this process, if the electrical signal emitted by the torque sensor suddenly becomes smaller, it means that after the pressing operation of the pressing plate 37, the connection effect of the object to be detected after being encapsulated by the UV curing glue is poor, and further testing of the encapsulation effect of the object to be detected is completed.

Use the camera 3 to take pictures, compare and analyze the pictures taken, and then obtain the packaging quality of the object.

[0020] In the present invention, when it is necessary to perform quality inspection on objects packaged with UV curing adhesive, the objects to be inspected are placed on the conveyor belt 8, and the dual-axis motor 5 is started. The dual-axis motor 5 drives the transmission rod 7 to rotate through the rotating shaft 6, and the transmission rod 7 drives the conveyor belt 8 and the objects placed on the conveyor belt 8 to move. During this process, the objects will pass through the area photographed by the camera 3, and the camera 3 will be used to photograph the objects, and the data obtained by the photography will be transmitted to the control center (such as a computer) for comparison and analysis, and then the packaging quality of the objects will be obtained. Then, in the process of the objects following the movement of the conveyor belt 8, under the limiting effect of the baffle 4, the objects can be effectively prevented from falling from the conveyor belt 8. The above are all existing technologies and no unnecessary elaboration will be made. In the process of the object following the movement of the conveyor belt 8, under the transmission action of the first pulley assembly 15 and the second pulley assembly 16, the rotating shaft 6 will drive all the first connecting rods 13 to rotate, and the first connecting rod 13 will drive the reciprocating screw 17 to rotate. Since the reciprocating screw 17 and the reciprocating block 18 are threadedly connected, and the reciprocating block 18 is slidably connected to the bracket 2 through the slide groove and the slide rod, the rotating reciprocating screw 17 will drive the reciprocating block 18 to move back and forth, and the reciprocating block 18 drives the trapezoidal plate 9 to move back and forth through the second connecting rod 14 and the first spring 11. In the process of the trapezoidal plate 9 moving back and forth, if the object to be detected is located between the two trapezoidal plates 9 at this time, the object will resist the side walls of the two trapezoidal plates 9 and move To the upper side of the two trapezoidal plates 9, the object to be detected and the conveyor belt 8 are disconnected, thereby causing the object to be detected to move upward relative to the workbench 1. When the two trapezoidal plates 9 are against each other, the two second connecting rods 14 will continue to move a distance towards each other under the action of the reciprocating block 18. At this time, the object to be detected stays on the upper side of the two trapezoidal plates 9, forming a brief relative stillness, thereby improving the camera 3's shooting effect of the object to be detected. And unlike when the object to be detected is placed on the conveyor belt 8, after the object to be detected and the trapezoidal plates 9 are against each other, the load-bearing surface of the object to be detected may change, which may cause the object to be detected to move, thereby further improving the shooting effect of the object to be detected; When the two trapezoidal plates 9 have not yet abutted against each other, under the obstruction of the limiting ball 32, a part of the stopper 33 extends into the square groove 10. When the second connecting rod 14 drives the trapezoidal plate 9 to move through the first spring 11, when the trapezoidal plate 9 and the object to be detected abut against each other, under the obstruction of the object to be detected, the trapezoidal plate 9 will move relative to the second connecting rod 14, thereby compressing the first spring 11 until the second connecting rod 14 and the stopper 33 abut against each other. In this process, since the third connecting plate 28 and the second connecting rod 14 are in a fixed state, the third connecting plate 28 will also move relative to the trapezoidal plate 9. However, under the obstruction of the stopper 33, the third connecting plate 28 will not abut against the swing tube 27. Then, between the two trapezoidal plates Before the two limit plates 30 collide with each other, the two limit plates 30 have already collided with each other. As the trapezoidal plate 9 continues to move, the limit plate 30 will move relative to the trapezoidal plate 9. While the limit plate 30 compresses the second spring 31, it drives the limit ball 32 to move. Since the inclined surface of the stop block 33 has been in contact with the limit ball 32, the stop block 33 will move downward under the action of its own gravity, thereby causing the second connecting rod 14 to lose the obstruction of the stop block 33. At this time, when the two trapezoidal plates 9 are completely in contact with each other, the second connecting rod 14 will move relative to the trapezoidal plate 9, and the third connecting plate 28 will collide with the swing tube 27. When the third connecting plate 28 and the swing tube 27 collide, due to the special shape of the third connecting plate 28 (the shape of the third connecting plate 28 is as shown in FIG. 2 ), the third connecting plate 28 is in contact with the swing tube 27. Figure 8As shown in the figure, when the third connecting plate 28 and the swing tube 27 abut against each other, due to the abutment between the side walls of the swing tube 27 and the third connecting plate 28, the swing tube 27 and the rotating rod 21 fixedly connected thereto will rotate under the obstruction of the third connecting plate 28, and the rotating rod 21 drives all other rotating rods 21 to rotate through the first gear 24 and the second gear 25, and the first gear 24 applies a force to the first torsion spring 34, causing the first torsion spring 34 to deform, and the rotating rod 21 drives the rotating tube 19 to rotate, and the rotating tube 19 drives the object to be detected to move, thereby causing the object to be detected to move relative to the trapezoidal plate 9, and then causing the object to be detected to move relative to the camera 3, and finally enabling the camera 3 to detect different angles of the object to be detected, thereby expanding the detection range of the camera 3 for the object to be detected, and combining with the attached Figure 8 The third connecting plate 28 has a special shape. When the third connecting plate 28 continues to move rightward, the movement direction of the swing tube 27 is rotation-reset-rotation-reset; In the process of the object to be detected moving along the trapezoidal plate 9, the object to be detected is located at the lower side of the pressing plate 37 and gradually approaches the pressing plate 37. When the object to be detected and the pressing plate 37 are against each other, the pressing plate 37 will drive the rotating ring 47 to rotate through the seventh connecting rod 48. The rotating ring 47 will not only make the torque sensor send out a corresponding electrical signal, but also cause the second torsion spring 46 to deform. Then, when the two trapezoidal plates 9 are completely against each other (that is, after the second connecting rod 14 loses the restriction of the block 33), when the pendulum cylinder 27 performs a rotation-reset-rotation-reset movement process under the action of the third connecting plate 28, the fourth connecting rod 26 that moves with the pendulum cylinder 27 will be against the eighth connecting rod 45, causing the eighth connecting rod 45 and the second connecting plate 28 to collide. 43 moves, the second connecting plate 43 causes the third spring 44 fixedly connected thereto to deform, and at the same time the eighth connecting rod 45 drives the third rack 42 to move, the third rack 42 drives the third gear 41 to rotate, and the third gear 41 drives the threaded ring 40 to rotate. Since the threaded ring 40 and the square groove 10 are in a rotating connection state, and the fifth connecting rod 38 and the square groove 10 on the trapezoidal plate 9 are slidably connected, the rotating threaded ring 40 causes the fifth connecting rod 38 to move relative to the trapezoidal plate 9, the fifth connecting rod 38 drives the sixth connecting rod 35 to move, the sixth connecting rod 35 drives the rotating ring 47 and the fixed ring 36 to move, and the rotating ring 47 drives the pressing plate 37 to move through the seventh connecting rod 48. In this case, the threaded rod 39 and the threaded ring 40 can be connected by 0's thread rotation direction controls the pressing plate 37 to move downward, so when the swing cylinder 27 performs a rotation-reset-rotation-reset motion process under the action of the third connecting plate 28, the motion trajectory of the pressing plate 37 is downward pressing-reset-downward pressing-reset, so that the force of the pressing plate 37 on the object to be detected can be gradually increased, thereby simulating the pressing operation on the object to be detected after being packaged, and the pressing is performed intermittently, and will not cause great damage to the object to be detected. In the above working process, when the swing cylinder 27 first abuts against the third connecting plate 28, under the action of the third connecting plate 28, the swing cylinder 27 and the rotating rod 21 will rotate around the rotating rod 21 as the center. In this process, when the corners of the swing cylinder 27 and the third connecting plate 28 abut against each other, The rotation angle of the pendulum 27 is the largest. At this time, the force exerted by the pressing plate 37 against the object to be detected on the object to be detected is the largest, until the third connecting plate 28 and the pendulum 27 are disconnected, that is, a "press down-reset" process is completed. During the continuous movement of the third connecting plate 28, when the pendulum 27 is against the third connecting plate 28 again, the pendulum 27 will swing again, and finally the pressing plate 37 will continue to perform the "press down-reset-press down-reset" process. In the whole process, the force exerted by the pressing plate 37 on the object to be detected is within a certain range, forming a pressing operation, and the size of the electrical signal emitted by the torque sensor is also within a certain range. During this process, if the electrical signal emitted by the torque sensor suddenly becomes smaller,This means that after the pressing operation of the pressing plate 37, the connection effect of the object to be detected after being encapsulated by the UV curing glue is poor, and further testing of the encapsulation effect of the object to be detected is completed.
