Description

Technical Field

[0001] This invention relates to a general apparatus for applying fluids to surfaces, and more particularly to an automatic feeding device and an automatic adhesive applicator for bolts. Background Technology

[0002] Existing bolt gluing machines require manual placement of the product to be glued onto the machine fixture and activation. The machine then automatically applies the glue according to preset requirements, and finally, the glued product is removed manually. On average, it takes 3-5 seconds to complete one product, resulting in low production efficiency.

[0003] Utility model patent CN215878572U discloses a multi-functional screw machine, including an industrial control computer. The industrial control computer is equipped with a cooperating conveying mechanism and a feeding mechanism. A linear conveyor line is located on one side of the feeding mechanism and supported by a support frame on the top of the industrial control computer. A limiting baffle is provided at the end of the linear conveyor line away from the feeding mechanism. A double support rod is located on the top of the industrial control computer in the direction of the limiting baffle and corresponding to the conveying mechanism. A drag chain type moving mechanism is provided on the top of the double support rod. A lifting mechanism is provided on the drag chain type moving mechanism. An inlet guide plate is located on the opposite side of the conveying mechanism and on one side of the double support rod. A dispensing mechanism is located on one side of the inlet guide plate and supported by a support block on the top of the industrial control computer. A displacement mechanism is located on the top of the industrial control computer near the same side of the inlet guide plate and the dispensing mechanism. An inclined support plate is provided on the top of the displacement mechanism, and a bracket for placing bolts is inclined on the top of the support plate. This utility model only requires manual replenishment of bolts in batches on time, while the feeding mechanism automatically transports the bolts; the equipment automatically applies glue to the bolts, and after the glue is applied, it automatically slides to the unloading bracket; the manual person can remove the entire full bracket and replace it with a bracket with holes, which improves the overall production efficiency of the device. However, its feeding mechanism has a very complex structure and a high failure rate during use.

[0004] To address the issue of complex feeding mechanisms, utility model patent CN217750579U discloses a feeding device for CNC milling machines with cutting quantity control function, which can be used for feeding screw machines. The feeding device includes a base, a bracket installed at the upper end of one side of the base, a holding box installed at the upper end of the bracket, a discharge port at the bottom end of the holding box, a rotating wheel installed on one side of the discharge port at the bottom end of the holding box, grooves provided around the outer perimeter of the rotating wheel, both ends of the rotating wheel being rotatably mounted on the upper end of a bearing seat, the bottom end of the bearing seat being mounted on the upper end of the base, one end of the rotating wheel extending out of the bearing seat and mounted at the front end of a motor, the motor being fixedly mounted on the upper end of a mounting platform by bolts, the mounting platform being fixedly mounted on the upper end of the base by bolts, a telescopic rod installed at the upper end of the mounting platform, and a top plate installed at the front end of the telescopic rod. Although the structure is simple, the container used to transport bolts only releases the bolts through the discharge port. There is no device at the discharge port to ensure that the bolts are accurately released into the groove position. Therefore, it may cause the bolts to be released incompletely, or even release multiple bolts at once. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic feeding device that solves the problem in the prior art where the feeding mechanism fails to release the bolts properly or even releases multiple bolts at once when applying adhesive to bolts.

[0006] The automatic feeding device of the present invention adopts the following technical solution:

[0007] An automatic feeding device includes a parts slide rail and a rotary feeding mechanism. The rotary feeding mechanism is located at the outlet of the parts slide rail and is rotatably mounted about a horizontal axis. A movable gate is rotatably mounted at the outlet of the parts slide rail about a horizontal axis. The movable gate has a blocking part for blocking the outlet. The movable gate is equipped with a retaining spring to keep the blocking part in the blocked outlet position. The rotary feeding mechanism is equipped with an unlocking lever that cooperates with the movable gate and, when the rotary feeding mechanism rotates, actuates the movable gate to overcome the elastic force of the retaining spring and cause it to rotate in the forward direction about its axis to open the outlet. The unlocking lever is located in front of the material trough of the rotary feeding mechanism in the rotation direction so that parts can enter the material trough when the movable gate opens the outlet. The movable gate also includes a blocking part that blocks subsequent parts when it rotates about its axis to open the outlet by the blocking part. After the unlocking lever slides past the movable gate as the rotary feeding mechanism rotates, the retaining spring causes it to rotate in the opposite direction to block the blocking part and seal the outlet.

[0008] This invention improves upon existing feeding devices. Specifically, the automatic feeding device of this invention includes a parts slide rail and a rotary feeding mechanism. When the unlocking lever of the rotary feeding mechanism rotates and contacts the movable gate, it drives the blocking part on the movable gate to rotate forward. During the forward rotation, the blocking part cannot restrict the parts from sliding out, and the parts will eventually roll out from the outlet and into the material trough. The movable gate also includes a blocking part that blocks subsequent parts when it rotates around its axis to open the outlet. After the unlocking lever slides past the movable gate as the rotary feeding mechanism rotates, a retaining spring causes it to rotate in the opposite direction to block the outlet. In this way, when the movable gate opens the outlet, subsequent parts will be continuously blocked by the blocking part and will not roll out of the parts slide rail with the previous part, ensuring that only one part can be released at a time.

[0009] Furthermore, the movable gate arm includes a rotating shaft and a plate-shaped gate arm assembly connected to the rotating shaft. The plate-shaped gate arm assembly includes a plate-shaped lever arranged perpendicular to the rotating shaft. One end of the plate-shaped lever cooperates with the unlocking lever to form a receiving end, and the other end is the blocking part. The plate-shaped gate arm assembly also includes a blocking piece extending at a certain angle to the plate-shaped lever, and the blocking piece constitutes the blocking part.

[0010] The movable gate arm includes a plate-shaped gate arm assembly. This design makes the movable gate arm lightweight, and the plate-shaped gate arm assembly can be obtained by stamping, resulting in low manufacturing cost and simple manufacturing.

[0011] Furthermore, there are two or more plate-shaped gate arm assemblies, which are arranged at intervals along the axis of rotation.

[0012] At least two plate-shaped gate arm assemblies are arranged at intervals along the axis of rotation, which can increase the contact area with the parts, reduce the pressure between the plate-shaped gate arm assembly and the parts, reduce wear, and the interval arrangement can better restrict the position of the parts on the parts slide rail.

[0013] Furthermore, the retaining spring is a tension spring disposed between the shield and the part slide rail.

[0014] Compared to setting the retaining spring as another type of spring, setting up a structure that works with the tension spring is simpler and easier to operate.

[0015] Furthermore, the component slide rail frame includes a bottom support rail, a top limiting plate, and side plates on both sides of the top limiting plate. A first spring connecting rod parallel to the rotation axis is connected between the two side plates. A second spring connecting rod is provided through the blocking part of the plate-shaped gate arm assembly, keeping the two ends of the spring connected to the first spring connecting rod and the second spring connecting rod respectively, and keeping the spring in the middle position of the two side plates.

[0016] The parts slide rail includes a bottom support rail and a top limiting plate, which restricts the position of the parts on the slide rail, preventing any movement other than sliding along the bottom support rail. Side plates are provided on both sides of the top limiting plate, and a first spring connecting rod parallel to the rotation axis connects the two side plates. A second spring connecting rod passes through the blocking part of the plate-shaped gate arm assembly, keeping the two ends of the spring connected to the first and second spring connecting rods respectively, and keeping the spring in the middle position of the two side plates. Thus, pulling the holding spring can drive the plate-shaped gate arm assembly to move synchronously, eliminating the need for a holding spring for each plate-shaped gate arm assembly. This results in a simple structure, low cost, and the holding spring, located in the middle position of the two side plates, provides a more even distribution of elastic force to each plate-shaped gate arm assembly.

[0017] Furthermore, the angle formed by the sealing plate and the plate lever is just enough to accommodate a component.

[0018] The angle formed by the blocking plate and the plate lever is just enough to accommodate a part, which ensures that the part can slide out at the fastest speed when the movable gate opens the outlet, ensuring a rapid response when the device is in use.

[0019] Furthermore, the automatic feeding device also includes a limiting structure for ensuring that the movable gate blocks the outlet after the unlocking lever slides past the movable gate as the rotating feeding mechanism rotates.

[0020] The automatic feeding device is equipped with a limiting structure to ensure that the movable gate blocks the outlet after the unlocking lever slides past the movable gate as the rotating feeding mechanism rotates. This ensures that the movable gate returns to the starting position to block the outlet after each time it opens, thus guaranteeing the reliability of the device during use.

[0021] Furthermore, the limiting structure includes a stop bar disposed on a plate-shaped gate arm assembly near the end of the rotating shaft and a limiting groove disposed on the part slide rail frame that cooperates with the stop bar.

[0022] The stop bar on the plate-shaped gate arm assembly near the end of the rotating shaft and the limiting groove on the slide rail frame that mates with the stop bar utilize existing structures, saving manufacturing costs and making the structure simple and easy to install.

[0023] The automatic bolt adhesive application device of the present invention adopts the following technical solution:

[0024] An automatic bolt gluing device includes a feeding device and a gluing device. The feeding device is an automatic feeding device, comprising a parts slide rail and a rotary feeding mechanism. The rotary feeding mechanism is located at the outlet position of the parts slide rail and is rotatably mounted about a horizontal axis. A movable gate is rotatably mounted at the outlet of the parts slide rail about a horizontal axis. The movable gate has a blocking part for blocking the outlet, and the movable gate is equipped with a retaining spring to keep the blocking part in the blocking position. The rotary feeding mechanism is provided with a mechanism that cooperates with the movable gate and actuates when the rotary feeding mechanism rotates. The movable gate lever is an unlocking lever that overcomes the elastic force of the retaining spring to rotate in the positive direction around its axis to open the outlet. The unlocking lever is located in front of the material trough of the rotary feeding mechanism in the rotation direction so that parts can enter the material trough when the movable gate lever opens the outlet. The movable gate lever also includes a blocking part that blocks subsequent parts when it rotates around its axis to open the outlet. After the unlocking lever slides past the movable gate lever as the rotary feeding mechanism rotates, the retaining spring causes it to rotate in the opposite direction to block the outlet. The glue applicator is located on one side of the automatic feeding device.

[0025] The automatic bolt gluing device of the present invention improves upon the original bolt gluing device. Specifically, the automatic bolt gluing device of the present invention includes an automatic feeding device and a gluing device. The automatic feeding device includes a parts slide rail and a rotary feeding mechanism. When the unlocking lever of the rotary feeding mechanism rotates and contacts the movable gate, it drives the sealing part provided on the movable gate to rotate forward together. During the forward rotation, the sealing part cannot restrict the parts from sliding out, and the parts will eventually roll out from the outlet and into the material trough. The movable gate also includes a blocking part that blocks subsequent parts when it rotates around its axis to open the outlet. After the unlocking lever slides past the movable gate with the rotation of the rotary feeding mechanism, the retaining spring causes it to rotate in the opposite direction to block the sealing part and seal the outlet. In this way, when the movable gate opens the outlet, subsequent parts will be continuously blocked by the blocking part and will not roll out of the parts slide rail with the previous part, ensuring that only one part can be released at a time.

[0026] Furthermore, the movable gate arm includes a rotating shaft and a plate-shaped gate arm assembly connected to the rotating shaft. The plate-shaped gate arm assembly includes a plate-shaped lever arranged perpendicular to the rotating shaft. One end of the plate-shaped lever cooperates with the unlocking lever to form a receiving end, and the other end is the blocking part. The plate-shaped lever also includes a blocking piece extending at a certain angle to the plate-shaped lever, and the blocking piece constitutes the blocking part.

[0027] The movable gate arm includes a plate-shaped gate arm assembly. This design makes the movable gate arm lightweight, and the plate-shaped gate arm assembly can be obtained by stamping, resulting in low manufacturing cost and simple manufacturing.

[0028] Furthermore, there are two or more plate-shaped gate arm assemblies, which are arranged at intervals along the axis of rotation.

[0029] At least two plate-shaped gate arm assemblies are arranged at intervals along the axis of rotation. This increases the contact area with the bolts, reduces the pressure between the plate-shaped gate arm assembly and the contact surface of the parts, reduces wear, and the interval arrangement can better restrict the position of the parts on the parts slide rail.

[0030] Furthermore, the retaining spring is a tension spring disposed between the shield and the part slide rail.

[0031] Compared to setting the retaining spring as another type of spring, setting up a structure that works with the tension spring is simpler and easier to operate.

[0032] Furthermore, the component slide rail frame includes a bottom support rail, a top limiting plate, and side plates on both sides of the top limiting plate. A first spring connecting rod parallel to the rotation axis is connected between the two side plates. A second spring connecting rod is provided through the blocking part of the plate-shaped gate arm assembly, keeping the two ends of the spring connected to the first spring connecting rod and the second spring connecting rod respectively, and keeping the spring in the middle position of the two side plates.

[0033] The parts slide rail includes a bottom support rail and a top limiting plate, which restricts the position of the parts on the slide rail, preventing any movement other than sliding along the bottom support rail. Side plates are provided on both sides of the top limiting plate, and a first spring connecting rod parallel to the rotation axis connects the two side plates. A second spring connecting rod passes through the blocking part of the plate-shaped gate arm assembly, keeping the two ends of the spring connected to the first and second spring connecting rods respectively, and keeping the spring in the middle position of the two side plates. Thus, pulling the holding spring can drive the plate-shaped gate arm assembly to move synchronously, eliminating the need for a holding spring for each plate-shaped gate arm assembly. This results in a simple structure, low cost, and the holding spring, located in the middle position of the two side plates, provides a more even distribution of elastic force to each plate-shaped gate arm assembly.

[0034] Furthermore, the angle formed by the sealing plate and the plate lever is just enough to accommodate a component.

[0035] The angle formed by the blocking plate and the plate lever is just enough to accommodate a part, which ensures that the part can slide out at the fastest speed when the movable gate opens the outlet, ensuring a rapid response when the device is in use.

[0036] Furthermore, the automatic feeding device also includes a limiting structure for ensuring that the movable gate blocks the outlet after the unlocking lever slides past the movable gate as the rotating feeding mechanism rotates.

[0037] The automatic feeding device is equipped with a limiting structure to ensure that the movable gate blocks the outlet after the unlocking lever slides past the movable gate as the rotating feeding mechanism rotates. This ensures that the movable gate returns to the starting position to block the outlet after each time it opens, thus guaranteeing the reliability of the device during use.

[0038] Furthermore, the limiting structure includes a stop bar disposed on a plate-shaped gate arm assembly near the end of the rotating shaft and a limiting groove disposed on the part slide rail frame that cooperates with the stop bar.

[0039] The stop bar on the plate-shaped gate arm assembly near the end of the rotating shaft and the limiting groove on the slide rail frame that mates with the stop bar utilize existing structures, saving manufacturing costs and making the structure simple and easy to install.

Detailed Implementation

[0044] The features and performance of the automatic bolt gluing device of the present invention will be further described in detail below with reference to embodiments.

[0045] Embodiment 1 of the automatic bolt gluing device of the present invention:

[0046] like Figure 1 and Figure 2 As shown, the automatic bolt gluing device of this embodiment includes an automatic feeding device and a gluing device. The automatic feeding device includes a parts slide rail 1 and a rotary feeding device. The rotary feeding device is rotatably installed around a horizontal axis at the outlet position of the parts slide rail 1. The rotary feeding device is provided with a material groove 9 for accommodating bolts.

[0047] The rotating shaft 21 is arranged at the outlet of the part slide rail frame 1. A movable brake rod 2 is connected to the rotating shaft 21. The movable brake rod 2 is in a "卜" shape, and a blocking part for blocking the outlet is arranged thereon. In order to ensure that the blocking part can always block the outlet, a holding spring 4 for keeping the blocking part in the blocking position is also arranged on the movable brake rod 2.

[0048] An unlocking lever 3 that cooperates with the movable brake rod 2 to complete the release of parts is arranged on the rotary feeding device. The unlocking lever 3 is located on the front side of the chute 9 of the rotary feeding mechanism in the rotating direction. This can ensure that after the unlocking lever 3 and the movable brake rod 2 cooperate to complete the release of the bolt, the bolt can enter the chute 9 behind the unlocking lever 3 in the rotating direction. When the unlocking lever 3 rotates and slides past the movable brake rod 2, the movable brake rod 2 will rotate forward around the rotating shaft 21 against the elastic force of the holding spring 4, and the blocking part of the movable brake rod 2 will open to release the bolt. After the unlocking lever 3 slides past the movable brake rod 2 and the two are separated from contact, the holding spring 4 will bring the movable brake rod 2 to rotate backward, and the blocking part will continue to block the outlet. A blocking part 24 for blocking the subsequent bolts from sliding out when the movable brake rod 2 rotates forward to open the blocking part and release the bolt is also arranged on the movable brake rod 2. In this way, when the bolt is released, the subsequent bolts will not pass through the movable brake rod 2, ensuring that each opening and closing of the blocking part on the movable brake rod 2 can only release one bolt. After the bolt enters the chute 9, it will be driven to rotate by the rotary feeding device. The gluing device on one side of the rotary feeding device will perform gluing operations on the bolts passing through it. After gluing is completed, the rotary feeding device continues to drive the bolt to rotate through a certain angle, and finally the bolt rolls out of the chute 9 and can be collected manually.

[0049] The part slide rail frame 1 includes a bottom drag rail 11 for placing bolts. The bottom drag rail 11 is at a certain angle with the horizontal plane. In this way, when the bolts are placed on the bottom drag rail 11, they will slide down to the outlet due to their own gravity, and there is no need to set other mechanisms to push the bolts to move, saving costs. A top limit plate 12 is arranged above the bottom drag rail 11. The top limit plate 12 is arranged parallel to the bottom drag rail 11, and the distance between the two is slightly larger than the diameter of the bolt to ensure that the bolt can pass through easily. Side plates 13 are arranged on both sides of the top limit plate 12.

[0050] A rotating shaft 21 is provided between the two side plates 13. The axis of the rotating shaft 21 is the same as that of the rotary feeding device and is horizontal. The movable brake rod 2 is rotatably mounted on the rotating shaft 21. The movable brake rod 2 includes two sheet brake rod assemblies 22. Of course, in other embodiments, the number of sheet brake rod assemblies 22 can also be three or more. The sheet brake rod assemblies 22 can be formed by stamping during manufacturing, which is simple in production and low in cost. And the two sheet brake rod assemblies 22 are arranged at intervals along the axis of the rotating shaft 21. Such an arrangement can increase the contact area with the bolt, reduce the pressure on the contact surface between the sheet brake rod assembly 22 and the bolt, reduce wear, and the spaced arrangement can better limit the position of the bolt on the bottom rail 11.

[0051] The sheet brake rod assembly 22 is in a "卜" shape. The vertical segment of the "卜" shape is perpendicular to the rotating shaft 21 and forms a sheet lever. One end of the sheet lever that cooperates with the unlocking lever 3 is the receiving end 23, and the other end is the blocking portion 24. The blocking portion 24 is responsible for continuously blocking the subsequent bolts from sliding out when the unlocking lever 3 rotates and slides past the receiving end 23 and the receiving end 23 rotates forward to release the bolt. The sheet lever further includes a blocking piece 25 extending at an angle to the sheet lever. The blocking piece 25 constitutes the blocking portion. The angle formed by the blocking piece 25 and the sheet lever just satisfies the accommodation of one bolt. In this way, when the blocking piece 25 rotates forward to open the outlet, the bolt can slide out at the fastest speed.

[0052] The holding spring 4 is a tension spring. A first spring connecting rod 7 is provided between the two side plates 13 parallel to the rotating shaft 21. A second spring connecting rod 8 is passed through the blocking portion 24 of the sheet brake rod assembly 22. The two ends of the holding spring 4 are respectively connected to the first spring connecting rod 7 and the second spring connecting rod 8, and the holding spring 4 is located in the middle position between the two side plates 13. In this way, by pulling the holding spring 4, the sheet brake rod assembly 22 can be driven to move synchronously. There is no need to provide a holding spring for each sheet brake rod assembly 22. The structure is simple and the cost is low. And the holding spring 4 is located in the middle position between the two side plates 13, and the elastic force provided can be more evenly distributed to each sheet brake rod assembly 22.

[0053] As Figure 3 shown, a stop rod 5 is provided on the sheet brake rod assembly 22 near the end of the rotating shaft 21, and an arc-shaped limiting groove 6 is opened on the corresponding side plate 13. The stop rod 5 is located in the limiting groove 6 and cooperates with each other to enable the movable brake rod 2 to block the outlet on the part slide rail rack 1 after the unlocking lever 3 rotates with the rotary feeding mechanism and slides past the movable brake rod 2.

[0054] During use, the bolts to be glued are sequentially placed on the bottom track 11 of the part slide rail frame 1. Since the bottom track has an angle with the horizontal plane, the bolts will slide along the bottom track 11 towards the outlet of the part slide rail frame 1. At this time, the movable gate rod 2 located at the outlet position of the part slide rail frame 1 will block the sliding out of the bolts. Then, the rotary feeding mechanism is started. There is a chute 9 for accommodating bolts on the rotary feeding mechanism. On the front side of the chute 9 of the rotary feeding mechanism in the rotational direction, there is an unlocking lever 3 that cooperates with the movable gate rod 2. When the unlocking lever 3 passes by the movable gate rod 2, it contacts the receiving end 23, and the receiving end 23 is driven to start rotating forward. At this time, the blocking piece 25 located on the movable gate rod 2 also rotates forward accordingly. When the stop rod 5 provided on the movable gate rod 2 moves to the extreme position of the limit groove 6, the blocking piece 25 will no longer be able to block the sliding out of the bolts. At this time, the chute 9 is exactly aligned with the outlet of the part slide rail frame 1, and the bolts will slide into the chute. When the blocking piece 25 is driven to rotate forward, the shielding portion 24 on the movable gate rod 2 continuously shields the subsequent bolts, preventing the subsequent bolts from sliding out.

[0055] After the bolts slide into the chute 9, the unlocking lever 3 is disengaged from the receiving end 23. Because a second spring connecting rod 8 passed through the shielding portion 24 of the movable gate rod 2 is connected with a holding spring 4, and the other end of the holding spring 4 is connected to the first spring connecting rod 7, and the holding spring 4 is a tension spring, the holding spring 4 will then pull the movable gate rod 2 to rotate reversely. When the stop rod 5 moves to the other extreme position of the limit groove 6, the next bolt will slide behind the blocking piece 25, and the shielding portion 24 will block the sliding out of the subsequent bolts. When the next unlocking lever 3 rotates to the receiving end 23 of the movable gate rod 2, the above process is repeated.

[0056] In the second embodiment of the bolt automatic gluing device of the present invention, different from the first embodiment, only the holding spring itself is used for limiting, and no limiting structure is provided anymore.

[0057] In the third embodiment of the bolt automatic gluing device of the present invention, different from the first embodiment, the movable gate rod is a profile with a "卜" - shaped cross - section, and the width of the movable gate rod is slightly smaller than the length of the rotating shaft, ensuring that the movable gate rod can rotate normally, and no sheet - like gate rod assembly is provided anymore.

[0058] In the fourth embodiment of the bolt automatic gluing device of the present invention, different from the first embodiment, there are three sheet - like gate rod assemblies. Two of the sheet - like gate rod assemblies are arranged at both ends of the rotating shaft, and the other is arranged in the middle of the rotating shaft. The shielding portions of the three sheet - like gate rod assemblies are penetrated with second spring connecting rods. The second spring connecting rods between adjacent two sheet - like gate rod assemblies are respectively connected with a first holding spring and a second holding spring. The first holding spring and the second holding spring are exactly the same. The other ends of the first holding spring and the second holding spring are both connected to the first spring connecting rod that is parallel to the rotating shaft and arranged between the two side plates.

[0059] The fifth embodiment of the automatic bolt gluing device of the present invention differs from the first embodiment in that a torsion spring is provided at the rotating shaft, one end of the torsion spring is connected to the rotating shaft, and the other end is fixed to the side plate.

[0060] The sixth embodiment of the automatic bolt gluing device of the present invention differs from the first embodiment in that a stop bar is provided at the position of the movable gate arm at the reverse rotation limit position, and the stop bar is located in the middle of the two side plates.

[0061] The automatic feeding device of the present invention has the same structure as the automatic feeding device in the above embodiments, and its embodiments will not be described again here.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.

The material trough and the movable gate lever also include a blocking part that blocks subsequent parts when the blocking part opens the outlet by rotating in the forward direction around its axis. After the unlocking lever slides past the movable gate lever with the rotational feeding mechanism, the retaining spring causes it to rotate in the reverse direction to block the outlet. The movable gate lever includes a rotating shaft and a plate-shaped gate lever assembly connected to the rotating shaft. The plate-shaped gate lever assembly includes a plate-shaped lever arranged perpendicular to the rotating shaft. One end of the plate-shaped lever cooperates with the unlocking lever to form a receiving end, and the other end is the blocking part. The plate-shaped gate lever assembly also includes a blocking plate that extends at a certain angle to the plate-shaped lever. The blocking plate constitutes the blocking part. The glue applicator is located on one side of the automatic feeding device. The angle formed by the blocking plate and the plate-shaped lever is just enough to accommodate one part.
