Since the pushing block resists the back plate and the back plate is already in a fixed state, the strong elastic column is squeezed and contracted, and the moving block continues to move and squeezes the positioning block, causing the positioning block to move toward the outside of the slide rail, the positioning block drives the connecting plate to move toward the outside of the slide rail, and the connecting plate drives the fixed block to move toward the outside of the slide rail, so that the back plate is unlocked, and the strong elastic column pops out at this time, and the strong elastic column pushes the pushing block, and the pushing block can continue to push the back plate to move backward, thereby discharging the material, which is the second moving state of the feeding device. Using this feeding device, the purpose of automatic feeding positioning and automatic unlocking can be achieved, so that the feeding and discharging automation of the bonding device is higher, and will not affect the positioning and fixation during bonding.

When the pressure cover moves upward, the pressure cover pulls the support rod, the support rod pulls the sliding base, and the sliding base pulls the glue spray box, so that the glue spray box reaches the operation point. When the pressure cover moves downward, the pressure cover pushes the support rod, the support rod pushes the sliding base, and the sliding base drives the glue spray box to leave the bottom surface of the pressure cover, and the glue spray box reaches the stop point. In this way, the glue spray box can coat the back plate with glue without affecting the pressing device, making the use of the glue coating device more flexible and convenient; making the glue collecting box, the guide plate, and the uniform The glue plate, thin elastic rod and elastic cylinder cooperate with each other, and the glue spray box drives the glue collecting box to move. The glue collecting box is used to scrape glue on both sides of the back plate to avoid glue overflow. At the same time, the guide plate can guide the scraped glue to avoid glue accumulation at the glue inlet of the glue collecting box. The elastic cylinder pushes the glue spreading plate, and the thin elastic rod is extended to push the glue spreading plate toward the inside of the glue collecting box. When the connecting plate rebounds and resets, the thin elastic rod will also rebound and reset, and the thin elastic rod will pull back the glue spreading plate. The movement of the glue spreading plate is used to push and stir the glue, so that the glue can be evenly stored inside the glue collecting box to avoid glue clogging at the glue inlet of the glue collecting box.

[0038] The glue coating device 4 includes a support rod 41, a sliding base 42 and a glue spray box 43. The top end of the support rod 41 is hinged on the side of the pressure cover 22. When the pressure cover 22 moves upward, the pressure cover 22 pulls the support rod 41, and the sliding base 42 is hinged on the other end of the support rod 41. The support rod 41 pulls the sliding base 42, and the sliding base 42 is slidably installed on the top surface of the workbench 1. The glue spray box 43 is fixed to the inner wall of the sliding base 42 through a round rod. The sliding base 42 pulls the glue spray box 43 so that the glue spray box 43 reaches the operating point. When the pressure cover 22 moves downward, the pressure cover 22 pushes the support rod 41, the support rod 41 pushes the sliding base 42, and the sliding base 42 drives the glue spray box 43 to leave the bottom surface of the pressure cover 22, and the glue spray box 43 reaches the stop point. In this way, the glue spray box 43 can perform glue coating on the back plate without affecting the pressing device 2, making the use of the glue coating device 4 more flexible and convenient.

[0039] The glue coating device 4 also includes a glue collecting box 44, a guide plate 45, a glue leveling plate 46, a thin elastic rod 47 and an elastic cylinder 48. The glue collecting box 44 is fixed to the side of the glue spraying box 43. When the back plate is coated with glue, glue may overflow on both sides of the back plate. The glue overflow may affect the quality of the finished product and may also cause the back plate to adhere to the subsequent assembly line. Therefore, when the glue spraying box 43 moves, the glue spraying box 43 drives the glue collecting box 44 to move, and the glue collecting box 44 is used to scrape glue on both sides of the back plate to avoid the occurrence of glue overflow. The guide plate 45 is fixed to the bottom surface of the inner wall of the glue collecting box 44. At the same time, the guide plate 45 can guide the scraped glue to avoid glue accumulation at the glue inlet of the glue collecting box 44. The glue leveling plate 46 is slidably installed on the inner wall of the glue collecting box 44. One end of the thin elastic rod 47 is fixed to the inner wall of the glue collecting box 44. The other end is fixed to the side of the glue plate 46, the elastic cylinder 48 is fixed to the top surface of the connecting plate 38, the top surface of the long box 39 is provided with a through groove for the movement of the elastic cylinder 48, and the guide plate 45 is located on the movement track of the elastic cylinder 48. When the glue spray box 43 is at the operation point, the feeding device 3 is in a working state, and the connecting plate 38 will move to the outside of the slide rail 32 during this period, and the connecting plate 38 drives the elastic cylinder 48 to move, and the elastic cylinder 48 pushes the glue plate 46, and the thin elastic rod 47 is extended, so that the glue plate 46 is pushed to the inside of the glue collection box 44. When the connecting plate 38 rebounds and resets, the thin elastic rod 47 will also rebound and reset, and the thin elastic rod 47 pulls back the glue plate 46, and the movement of the glue plate 46 is used to push and stir the glue, so that the glue can be evenly stored in the glue collection box 44, and the glue is prevented from being blocked at the glue inlet of the glue collection box 44.

[0040] The safety device 5 includes a reset spring rod 51, a telescopic stopper 52 and a handle 53. The reset spring rod 51 is fixed on both sides of the inner wall of the operation compartment on the top surface of the workbench 1. The telescopic stopper 52 is fixed on the telescopic end of the reset spring rod 51. The bottom of the telescopic end of the telescopic stopper 52 is a beveled surface. The telescopic stopper 52 is located on the movement trajectory of the gland 22. When the pressing device 2 is in operation, the telescopic stopper 52 is used to block and limit the movement path of the gland 22 in order to protect the safety of the operator. The telescopic stopper 52 is slidably installed on both sides of the inner wall of the operation compartment on the top surface of the workbench 1. The handle 53 is fixed on the front of the telescopic stopper 52. The operator needs to pull the handle 53. The handle 53 pulls the telescopic stopper 52 so that the telescopic stopper 52 leaves the movement track of the gland 22. At this time, the gland 22 can be pressed down normally to fit. The bottom of the telescopic end of the telescopic stopper 52 is provided with a beveled surface, so that the operator does not need to pull the handle 53 all the time. Even if the reset spring rod 51 drives the telescopic stopper 52 back to the movement path of the gland 22, the beveled surface of the telescopic end of the telescopic stopper 52 can be squeezed when the gland 22 rises, so that the telescopic end of the telescopic stopper 52 retracts, which will not affect the resetting of the gland 22. This device is used to protect the hands of the operator, avoid the gland 22 from crushing the operator, and reduce the occurrence of work-related injuries.

[0041] The safety device 5 also includes a horizontal block 54, a trapezoidal block 55, a squeeze plate 56 and a special-shaped connecting block 57. The horizontal block 54 is fixed on both sides of the inner wall of the operation chamber on the top surface of the workbench 1. The trapezoidal block 55 penetrates and is slidably installed on the bottom surface of the horizontal block 54. The trapezoidal block 55 is located on the movement track of the telescopic stopper 52. The squeeze plate 56 is slidably installed on the bottom surface of the inner wall of the handle 53. In actual operation, the operator may use one hand to pull the handle 53 for convenience. Therefore, the safety device 5 requires the operator to press the squeeze plate 56 with both hands. A special-shaped connecting block 57 is set between the squeeze plate 56 and the inner wall side of the handle 53. There is a spring, and the special-shaped connecting block 57 is slidably installed on the inner wall side of the handle 53. The special-shaped connecting block 57 is located on the movement trajectory of the extrusion plate 56. The extrusion plate 56 pushes and squeezes the special-shaped connecting block 57, so that the special-shaped connecting block 57 moves upward. The trapezoidal block 55 is located on the movement trajectory of the special-shaped connecting block 57. The special-shaped connecting block 57 pushes the trapezoidal block 55 upward, so that the trapezoidal block 55 is retracted into the inside of the cross block 54. The trapezoidal blocks 55 leave the movement trajectory of the telescopic stopper 52. At this time, the operator can pull the telescopic stopper 52 to achieve the purpose of forcing both hands to unlock, thereby further protecting the safety of the operator.

[0042] When in use, when the pressure cover 22 moves upward, the pressure cover 22 pulls the support rod 41, the support rod 41 pulls the sliding base 42, and the sliding base 42 pulls the glue spraying box 43, so that the glue spraying box 43 reaches the operating point; when the pressure cover 22 moves downward, the pressure cover 22 pushes the support rod 41, the support rod 41 pushes the sliding base 42, and the sliding base 42 drives the glue spraying box 43 to leave the bottom surface of the pressure cover 22, and the glue spraying box 43 reaches the stopping point. In this way, the glue spraying box 43 can apply glue to the back plate without affecting the pressing device 2, making the use of the glue coating device 4 more flexible and convenient; when applying glue to the back plate, glue overflow may occur on both sides of the back plate, which may affect the quality of the finished product and may also cause the back plate to adhere to the subsequent assembly line. Therefore, when the glue spraying box 43 moves, the glue spraying box 43 drives The glue collecting box 44 moves, and the glue collecting box 44 is used to scrape glue on both sides of the back plate to avoid glue overflow. At the same time, the guide plate 45 can guide the scraped glue to avoid glue accumulation at the glue inlet of the glue collecting box 44. When the glue spraying box 43 is at the operating point, the feeding device 3 is in a working state. The connecting plate 38 will move toward the outside of the slide rail 32 during this period, and the connecting plate 38 drives the elastic cylinder 48 to move. The elastic cylinder 48 pushes the glue leveling plate 46, and the thin elastic rod 47 extends, so that the glue leveling plate 46 is pushed toward the inside of the glue collecting box 44. When the connecting plate 38 rebounds and resets, the thin elastic rod 47 will also rebound and reset. The thin elastic rod 47 pulls back the glue leveling plate 46, and the movement of the glue leveling plate 46 is used to push and level the glue, so that the glue can be evenly stored in the glue collecting box 44 to avoid glue clogging at the glue inlet of the glue collecting box 44.

[0043] When the pressing device 2 is in operation, in order to protect the safety of the operator, the telescopic stopper 52 is used to block and limit the moving path of the pressing cover 22. The operator needs to pull the handle 53, and the handle 53 pulls the telescopic stopper 52, so that the telescopic stopper 52 leaves the moving track of the pressing cover 22. At this time, the pressing cover 22 can be pressed down normally for fitting. The bottom of the telescopic end of the telescopic stopper 52 is provided with a beveled surface, so that the operator does not need to keep pulling the handle 53. Even if the reset spring rod 51 drives the telescopic stopper 52 back to the moving path of the pressing cover 22, the beveled surface of the telescopic end of the telescopic stopper 52 can be squeezed when the pressing cover 22 rises, so that the telescopic end of the telescopic stopper 52 retracts without affecting the pressing cover. 22 is reset, and this device is used to protect the hands of the operator, so as to avoid the pressure cover 22 from crushing the operator and reducing the occurrence of work-related injuries. In actual operation, the operator may use one hand to pull the handle 53 for the sake of saving trouble. Therefore, the safety device 5 requires the operator to press the squeezing plate 56 with both hands. The squeezing plate 56 pushes the squeezing special-shaped connecting block 57 to make the special-shaped connecting block 57 move upward. The special-shaped connecting block 57 pushes the trapezoidal block 55 upward, so that the trapezoidal block 55 is retracted into the inside of the horizontal block 54. The trapezoidal blocks 55 leave the movement track of the telescopic stopper 52. At this time, the operator can pull the telescopic stopper 52 to achieve the purpose of forcing both hands to unlock, thereby further protecting the safety of the operator.
