Description

Technical Field

[0001] The utility model relates to the technical field of sorting and feeding, and particularly relates to an automatic plastic nail inserting mechanism for a test sorter. Background Art

[0002] A test sorter is an important testing device for material tubes such as triodes. It can perform insulation testing, electrical property testing, and classification of good and bad of triodes. Currently, one end of the material tube is provided with a jack for inserting a plastic nail. Before the material tube is fed, it is necessary to manually insert a plastic nail into one end of the material tube. The plastic nail can be used as a mechanical positioning reference for the material tube in the testing equipment. After the plastic nail is inserted into the material tube, through the cooperation of the plastic nail and the corresponding card slot on the equipment, it is ensured that the material tube maintains an accurate spatial position and direction during transmission and testing, avoiding problems such as poor contact between the test electrode and deviation of the test result caused by the shaking or offset of the material tube.

[0003] However, this manual method of inserting plastic nails requires workers to operate on each material tube one by one. Each material tube has to go through multiple steps such as taking, positioning, and inserting plastic nails. The operation is cumbersome and time-consuming. Especially when facing the feeding task of a large number of material tubes, this method seriously limits the overall work efficiency, resulting in a slow production progress and unable to meet the needs of large-scale production. During the process of inserting plastic nails, workers need to press the plastic nails hard to insert them firmly into the material tubes. Repeating such actions with fingers for a long time will cause workers' fingers to bear great pressure and easily lead to finger pain or even injury. Summary of the Utility Model

[0004] The problem to be solved by the utility model is to provide an automatic plastic nail inserting mechanism for a test sorter. This automatic plastic nail inserting mechanism for a test sorter can automatically insert plastic nails into the material tubes, improve the nail inserting speed and work efficiency, and reduce the labor intensity and work injury risk.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0006] An automatic plastic nail inserting mechanism for a testing and sorting machine, characterized in that: it includes a frame, a nail separating mechanism, a nail inserting mechanism, a material blocking and limiting mechanism, an auxiliary material pushing mechanism and an auxiliary unloading mechanism. The nail separating mechanism, the nail inserting mechanism, the material blocking and limiting mechanism, the auxiliary material pushing mechanism and the auxiliary unloading mechanism are all arranged on the frame. There is a storage channel on the frame that can place a material tube, and the storage channel has a first end and a second end; the nail inserting mechanism includes a nail inserting cylinder, a inserting rod and a positioning pipe through which plastic nails can pass. The nail inserting cylinder is installed on the frame, and the extending direction of the piston rod of the nail inserting cylinder is downward. The upper end of the inserting rod is connected to the end of the piston rod of the nail inserting cylinder. The positioning pipe is vertically installed on the frame, and the inserting rod is located in the positioning pipe. The lower end opening of the positioning pipe is above the storage channel and corresponds to the first end of the storage channel. The material blocking and limiting mechanism corresponds to the first end of the storage channel and is located outside the positioning pipe. The power output end of the auxiliary material pushing mechanism faces the second end of the storage channel; there is a nail storage tube at the upper end of the nail separating mechanism, and a tubular nail outlet communicating with the nail storage tube is provided at the lower end of the nail separating mechanism. The lower end outlet of the tubular nail outlet communicates with the inner cavity of the positioning pipe; the power output end of the auxiliary unloading mechanism faces the first end of the storage channel.

[0007] When inserting plastic nails, first place the material tube to be inserted with plastic nails in the storage channel of the frame so that the jack on the end of the material tube is below the lower end opening of the positioning pipe; then, put each plastic nail (with the head of the plastic nail facing up and the end of the rod facing down) into the nail storage tube; next, push the material tube towards the first end of the storage channel through the auxiliary material pushing mechanism, and use the material blocking and limiting mechanism to block one end of the material tube to ensure that the jack on the end of the material tube is precisely aligned with the lower end opening of the positioning pipe; then, convey the plastic nails to the tubular nail outlet through the nail separating mechanism, and the plastic nails enter the inner cavity of the positioning pipe along the tubular nail outlet and maintain a vertical posture; finally, drive the piston rod to move downward through the nail inserting cylinder, drive the inserting rod to press downward along the axis of the positioning pipe, and vertically insert the nail in the positioning pipe into the jack on the end of the material tube, thus completing the automatic plastic nail inserting operation. After a material tube is inserted with plastic nails, the auxiliary material pushing mechanism withdraws the push on the material tube, separates the end of the material tube from the material blocking and limiting mechanism through the power output end of the auxiliary unloading mechanism, and uses another material tube handling mechanism provided on the frame to move the material tube with plastic nails inserted away from the storage channel, and then perform the automatic plastic nail inserting operation on another material tube according to the above steps.

[0008] In a preferred embodiment, the nail separating mechanism includes a lower nail seat, a nail delivery hose, a blowing pipe, a blowing pump, a nail clamping sensor, a nail clamping driving mechanism, a clamping strip, a lower nail driving mechanism, a clamping plate, a lower nail sensor, the nail storage tube and the tubular nail outlet nozzle. The lower nail seat is installed on the frame. A sealing cavity is provided inside the lower nail seat. The nail storage tube is vertically installed on the lower nail seat and longitudinally passes through the sealing cavity. The middle part of the nail storage tube is successively provided with an upper nail clamping channel and a lower nail clamping channel from top to bottom. Both the upper nail clamping channel and the lower nail clamping channel are horizontally oriented and are both communicated with the inner cavity of the nail storage tube. The height between the upper nail clamping channel and the lower nail clamping channel is the height capable of accommodating one plastic glue nail. The nail clamping driving mechanism is installed on the lower nail seat. The clamping strip is installed on the power output end of the nail clamping driving mechanism. The clamping strip is located in the upper nail clamping channel and can move horizontally in the upper nail clamping channel. The nail clamping sensor is installed on the lower nail seat and is electrically connected to the signal input end of the nail clamping driving mechanism. The lower nail driving mechanism is installed on the lower nail seat. The clamping plate is installed on the power output end of the lower nail driving mechanism. The clamping plate is located in the lower nail clamping channel and can move horizontally in the lower nail clamping channel. The lower nail sensor is installed on the lower nail seat and is electrically connected to the signal input ends of the nail clamping sensor and the lower nail driving mechanism. The upper end of the nail delivery hose is connected to the lower end of the nail storage tube, and the lower end of the nail delivery hose is connected to the upper end of the tubular nail outlet nozzle. An air inlet communicated with the sealing cavity is provided on the lower nail seat. The upper end of the blowing pipe is connected to the air inlet, and the lower end of the blowing pipe is connected to the blowing pump. First, the clamping plate is driven by the lower nail driving mechanism to move horizontally so that the clamping plate extends into the lower nail clamping channel to seal the inner cavity of the nail storage tube. The clamping strip is driven by the nail clamping driving mechanism to move horizontally so that the clamping strip withdraws from the inner cavity of the nail storage tube. Then, each plastic glue nail is sequentially placed into the nail storage tube, and the plastic glue nails slide downward by their own gravity. When a plastic glue nail slides above the clamping plate (between the upper nail clamping channel and the lower nail clamping channel), the clamping strip is driven by the nail clamping driving mechanism to extend into the upper nail clamping channel and clamp the plastic glue nail so that the plastic glue nail stays at the upper nail clamping channel. At this time, the nail clamping sensor detects the presence of the plastic glue nail and transmits the signal to the lower nail sensor. After receiving the signal, the lower nail sensor transmits the signal to the lower nail driving mechanism. The lower nail driving mechanism drives the clamping plate to withdraw from the lower nail clamping channel, so that the plastic glue nail located on the clamping plate automatically falls into the nail delivery hose by gravity. At this time, the blowing pump is started to blow air. The air flow is sequentially blown into the sealing cavity of the lower nail seat and the nail delivery hose through the blowing pipe, and the plastic glue nail in the nail delivery hose is blown into the tubular nail outlet nozzle. The plastic glue nail enters the inner cavity of the positioning pipe along the tubular nail outlet nozzle under the action of the air flow and maintains a vertical posture by gravity or air flow. By providing the upper nail clamping channel and the lower nail clamping channel, as well as the corresponding nail clamping driving mechanism, nail clamping sensor, lower nail driving mechanism and lower nail sensor, the falling and supply rhythm of the plastic glue nails can be accurately controlled. The plastic glue nails are quickly transported from the lower nail clamping channel to the positioning pipe by blowing air, realizing the quick supply of the glue nails.Only one plastic nail is allowed to enter the positioning pipe at a time to avoid chaos caused by multiple nails entering simultaneously, and improve the accuracy and stability of nail insertion.

[0009] When the nail feeding sensor detects that the plastic nail on the clamping plate has fallen off, the nail feeding sensor transmits signals to the nail feeding driving mechanism and the nail clamping sensor successively: after receiving the signal, the nail feeding driving mechanism drives the clamping plate to extend into the lower nail clamping channel through the nail feeding driving mechanism, closing the inner cavity of the nail storage tube; then, the nail clamping sensor receives the signal and drives the clamping strip to withdraw from the upper nail clamping channel through the nail clamping driving mechanism, releasing the plastic nail in the upper nail clamping channel, so that the plastic nail falls above the clamping plate. After that, when the nail clamping sensor detects that the plastic nail in the upper nail clamping channel is not clamped, the nail clamping sensor transmits signals to the nail clamping driving mechanism and the nail feeding sensor successively: after receiving the signal, the nail clamping driving mechanism drives the clamping strip to extend into the upper nail clamping channel through the nail clamping driving mechanism, clamping the plastic nail in the upper nail clamping channel; then, the nail feeding driving mechanism receives the signal and drives the clamping plate to withdraw from the lower nail clamping channel through the nail feeding driving mechanism, so that the plastic nail on the clamping plate automatically falls into the nail feeding hose. Repeat the above steps to achieve continuous supply of plastic nails. At the same time, new plastic nails will be continuously replenished at the upper nail clamping channel to ensure the continuity of nail supply.

[0010] In a further preferred solution, the nail clamping driving mechanism includes a first moving seat, a first cylinder, a first guide rod and a first compression spring. The first moving seat is located outside the lower nail seat. The cylinder body of the first cylinder is installed on the first moving seat. The piston rod of the first cylinder extends in the horizontal direction, and the end of the piston rod of the first cylinder is connected to the outer wall of the lower nail seat. The nail clamping sensor is electrically connected to the signal input end of the first cylinder; the outer end of the first guide rod is installed on the first moving seat. The side wall of the lower nail seat is provided with a first guide hole extending horizontally. The first guide rod is located in the first guide hole. The clamping strip is installed at the inner end of the first guide rod; the first compression spring is sleeved on the first guide rod and is located between the first moving seat and the outer wall of the lower nail seat. The outer end of the first compression spring is in contact and cooperation with the inner surface of the first moving seat, and the inner end of the first compression spring is in contact and cooperation with the outer wall of the lower nail seat. Under normal conditions, the piston rod of the first cylinder is in the extended state, driving the clamping strip to withdraw from the upper nail clamping channel. When the nail feeding sensor detects that the plastic nail on the clamping plate has fallen off, the nail feeding sensor transmits the signal to the nail clamping sensor, and the nail clamping sensor then transmits the signal to the first cylinder. After receiving the signal, the first cylinder drives its piston rod to contract, thereby pulling the first moving seat to move towards the lower nail seat. At this time, the first guide rod slides in the first guide hole as the first moving seat moves. The first compression spring is compressed, and the clamping strip extends into the upper nail clamping channel as the first guide rod moves, thereby clamping the plastic nail in the upper nail clamping channel and keeping it at the upper nail clamping channel.

[0011] In a further preferred embodiment, an arc-shaped fork opening with an inward opening is provided at the inner end of the card strip. The arc-shaped fork opening is located in the inner cavity of the nail storage tube and can move horizontally in the upper nail clamping channel. The above-mentioned arc-shaped fork opening just faces the rod portion of the plastic adhesive nail. When the plastic adhesive nail is in the upper nail clamping channel, the piston rod of the first cylinder can drive the above-mentioned arc-shaped fork opening to fork the rod portion of the plastic adhesive nail, so as to better position the plastic adhesive nail in the upper nail clamping channel.

[0012] In a further preferred embodiment, the lower nail driving mechanism includes a second moving seat, a second cylinder, a second guide rod and a second compression spring. The second moving seat is located outside the lower nail seat. The cylinder block of the second cylinder is installed on the second moving seat. The extending direction of the piston rod of the second cylinder is horizontal, and the end of the piston rod of the second cylinder is connected to the outer wall of the lower nail seat. The lower nail sensor is electrically connected to the signal input end of the second cylinder; the outer end of the second guide rod is installed on the second moving seat. The side wall of the lower nail seat is provided with a second guide hole extending left and right. The second guide rod is located in the second guide hole. The card plate is installed at the inner end of the second guide rod; the second compression spring is sleeved on the second guide rod and is located between the second moving seat and the outer wall of the lower nail seat. The outer end of the second compression spring is in contact and cooperation with the inner surface of the second moving seat, and the inner end of the second compression spring is in contact and cooperation with the outer wall of the lower nail seat. Under normal conditions, the piston rod of the above-mentioned second cylinder is in the extended state, driving the card plate to withdraw from the lower nail clamping channel. When the nail clamping sensor detects that the plastic adhesive nail in the upper nail clamping channel is not clamped, the nail clamping sensor transmits the signal to the lower nail sensor, and the lower nail sensor then transmits the signal to the second cylinder. After receiving the signal, the second cylinder drives its piston rod to perform a contraction action, thereby pulling the second moving seat to move towards the direction close to the lower nail seat. At this time, the second guide rod slides in the second guide hole as the second moving seat moves. The second compression spring is compressed, and the card plate extends into the lower nail clamping channel as the second guide rod moves, so as to close the lower nail clamping channel.

[0013] In a further preferred embodiment, the card plate is provided with a nail dropping through hole for the plastic adhesive nail to drop and a cover surface capable of covering the inner cavity of the nail storage tube. The cover surface is located inside the nail dropping through hole. When the second cylinder drives its piston rod to perform a contraction action, driving the card plate to extend into the lower nail clamping channel, the nail dropping through hole communicates with the inner cavity of the nail storage tube, so that the plastic adhesive nail drops from the nail dropping through hole into the nail conveying hose. When the second cylinder drives its piston rod to perform an extension action, driving the card plate to withdraw from the lower nail clamping channel, the cover surface just covers the inner cavity of the nail storage tube, so that the plastic adhesive nail is temporarily stored on the card plate.

[0014] In a preferred embodiment, the material blocking and limiting mechanism includes an upper block and two lower blocks. The two lower blocks are arranged side by side on the frame. The lower block is provided with a lower V-shaped notch facing the first end of the material storage channel. The upper block is installed on the frame and above the two lower blocks. The upper block is provided with an upper V-shaped notch facing the first end of the material storage channel. When the auxiliary material pushing mechanism pushes the material tube towards the first end of the material storage channel, the upper edge of one end of the material tube is inserted into the upper V-shaped notch, and at the same time, the lower edge of this end of the material tube is inserted into the two lower V-shaped notches, so that the material tube can be better positioned when inserting the plastic nails, and avoid the position of the material tube shifting and the plastic nails not being inserted.

[0015] In a further preferred embodiment, the auxiliary unloading mechanism includes an unloading cylinder and an unloading block. A guide rail parallel to the material storage channel is provided on the frame, and one end of the guide rail corresponds to the first end of the material storage channel. The material blocking and limiting mechanism is located between the guide rail and the first end of the material storage channel. The unloading cylinder is installed on the frame, and the extending direction of the piston rod of the unloading cylinder faces the first end of the material storage channel. The unloading block is slidably installed on the guide rail and connected to the end of the piston rod of the unloading cylinder. A guide through hole through which the unloading block can pass is provided between the two lower blocks, and the upper block is located above the guide through hole. The above-mentioned unloading cylinder drives the unloading block to slide on the guide rail. When a material tube is inserted with plastic nails, the unloading cylinder drives the unloading block to slide along the guide rail and pass through the guide through hole, so that the unloading block pushes out towards the end of the material tube, making the end of the material tube disengage from the upper V-shaped notch and the two lower V-shaped notches, facilitating the unloading of the material tube.

[0016] In a preferred embodiment, the lower outlet edge of the tubular nail outlet nozzle is provided with an installation inclined surface. An inlet for the nail is provided on the lower side wall of the positioning pipe. The installation inclined surface is in close contact with the outer lower side wall of the positioning pipe. The tubular nail outlet nozzle is inclined and arranged on the lower side wall of the positioning pipe. The lower outlet of the tubular nail outlet nozzle communicates with the inner cavity of the positioning pipe through the inlet for the nail.

[0017] In a preferred embodiment, the auxiliary material pushing mechanism includes a pushing cylinder, a push rod and a push block. A third guide hole corresponding to one end of the material storage channel is provided on the frame. The pushing cylinder is installed on the frame, and the extending direction of the piston rod of the pushing cylinder faces the end of the material storage channel. The push rod is located in the third guide hole. One end of the push rod is connected to the end of the piston rod of the pushing cylinder, and the push block is installed on the other end of the push rod. The push block is located in the material storage channel. By the extension of the piston rod of the pushing cylinder, the push rod and the push block thereon are driven to push the material tube towards the other end of the material storage channel, ensuring that the insertion hole at the end of the material tube is accurately aligned with the lower opening of the positioning pipe.

[0019] The utility model adopts a combination of pneumatic conveying and mechanical insertion, which can not only improve the nail insertion speed and working efficiency to meet the requirements of large-scale production, but also completely replace the action of manually pressing the glue nails, eliminate the mechanical pressure endured by workers' fingers for a long time, and reduce the labor intensity and work injury risk.

[0028] The following specifically describes the utility model in conjunction with the drawings and specific embodiments.

[0029] As Figure 1-8As shown in the figure, the automatic plastic nail inserting mechanism of the test sorting machine in this embodiment includes a frame 1, a nail separating mechanism 2, a nail inserting mechanism 3, a material blocking and limiting mechanism 7, an auxiliary material pushing mechanism 4, and an auxiliary discharging mechanism 8. The nail separating mechanism 2, the nail inserting mechanism 3, the material blocking and limiting mechanism 7, the auxiliary material pushing mechanism 4, and the auxiliary discharging mechanism 8 are all arranged on the frame 1. A storage channel 11 capable of placing a material pipe 5 is provided on the frame 1. The storage channel 11 has a first end 111 and a second end 112; the nail inserting mechanism 3 includes a nail inserting cylinder 31, an inserting rod 32, and a positioning pipe 33 through which a plastic nail 6 can pass. The nail inserting cylinder 31 is installed on the frame 1, and the extending direction of the piston rod of the nail inserting cylinder 31 is downward. The upper end of the inserting rod 32 is connected to the end of the piston rod of the nail inserting cylinder 31. The positioning pipe 33 is vertically installed on the frame 1. The inserting rod 32 is located in the positioning pipe 33. The lower opening of the positioning pipe 33 is above the storage channel 11 and corresponds to the first end 111 of the storage channel 11. The material blocking and limiting mechanism 7 corresponds to the first end 111 of the storage channel 11 and is located outside the positioning pipe 33. The power output end of the auxiliary material pushing mechanism 4 faces the second end 112 of the storage channel 11; a nail storage pipe 23 is provided at the upper end of the nail separating mechanism 2, and a tubular nail outlet 21 communicating with the nail storage pipe 23 is provided at the lower end of the nail separating mechanism 2. The lower outlet of the tubular nail outlet 21 communicates with the inner cavity of the positioning pipe 33; the power output end of the auxiliary discharging mechanism 8 faces the first end 111 of the storage channel 11.

[0030] When inserting plastic nails, first place the material pipe 5 to be inserted with plastic nails in the storage channel 11 of the frame 1, so that the jack on the end of the material pipe 5 is below the lower opening of the positioning pipe 33; then, put each plastic nail 6 (with the head of the plastic nail 6 facing up and the end of the rod facing down) into the nail storage pipe 23; then, use the auxiliary material pushing mechanism 4 to push the material pipe 5 towards the first end 111 of the storage channel 11, and use the material blocking and limiting mechanism 7 to block one end of the material pipe 5 to ensure that the jack on the end of the material pipe 5 is accurately aligned with the lower opening of the positioning pipe 33; then, use the nail separating mechanism 2 to convey the plastic nail 6 to the tubular nail outlet 21, and the plastic nail 6 enters the inner cavity of the positioning pipe 33 along the tubular nail outlet 21 and maintains a vertical posture; finally, drive the piston rod of the nail inserting cylinder 31 to move downward, drive the inserting rod 32 to press downward along the axis of the positioning pipe 33, and vertically insert the nail in the positioning pipe 33 into the jack on the end of the material pipe 5, that is, complete the automatic plastic nail inserting operation. After a material pipe 5 is inserted with plastic nails, the auxiliary material pushing mechanism 4 withdraws the push on the material pipe 5, uses the power output end of the auxiliary discharging mechanism 8 to separate the end of the material pipe 5 from the material blocking and limiting mechanism 7, and uses another material pipe 5 handling mechanism on the frame 1 to move the material pipe 5 that has been inserted with plastic nails away from the storage channel 11, and then perform the automatic plastic nail inserting operation on another material pipe 5 according to the above steps.

[0031] The nail separating mechanism 2 includes a lower nail seat 22, a nail feeding hose 24, a blowing pipe 25, a blowing pump (not shown in the figure), a nail jamming sensor 27, a nail jamming driving mechanism 28, a clamping strip 29, a lower nail driving mechanism 201, a clamping plate 202, a lower nail sensor 203, a nail storage tube 23 and the tubular nail outlet nozzle 21. The lower nail seat 22 is installed on the frame 1. A sealing cavity 221 is provided inside the lower nail seat 22. The nail storage tube 23 is vertically installed on the lower nail seat 22 and longitudinally passes through the sealing cavity 221. An upper nail jamming channel 231 and a lower nail jamming channel 232 are sequentially provided from top to bottom in the middle of the nail storage tube 23. Both the upper nail jamming channel 231 and the lower nail jamming channel 232 are horizontally oriented and are both communicated with the inner cavity of the nail storage tube 23. The height between the upper nail jamming channel 231 and the lower nail jamming channel 232 is the height capable of accommodating one plastic glue nail 6. The nail jamming driving mechanism 28 is installed on the lower nail seat 22. The clamping strip 29 is installed on the power output end of the nail jamming driving mechanism 28. The clamping strip 29 is located in the upper nail jamming channel 231 and can move horizontally in the upper nail jamming channel 231. The nail jamming sensor 27 is installed on the lower nail seat 22 and is electrically connected to the signal input end of the nail jamming driving mechanism 28. The lower nail driving mechanism 201 is installed on the lower nail seat 22. The clamping plate 202 is installed on the power output end of the lower nail driving mechanism 201. The clamping plate 202 is located in the lower nail jamming channel 232 and can move horizontally in the lower nail jamming channel 232. The lower nail sensor 203 is installed on the lower nail seat 22 and is electrically connected to the signal input ends of the nail jamming sensor 27 and the lower nail driving mechanism 201. The upper end of the nail feeding hose 24 is connected to the lower end of the nail storage tube 23, and the lower end of the nail feeding hose 24 is connected to the upper end of the tubular nail outlet nozzle 21. An air inlet 222 communicated with the sealing cavity 221 is provided on the lower nail seat 22. The upper end of the blowing pipe 25 is connected to the air inlet 222, and the lower end of the blowing pipe 25 is connected to the blowing pump. First, the lower nail driving mechanism 201 drives the clamping plate 202 to move horizontally, so that the clamping plate 202 extends into the lower nail jamming channel 232 to seal the inner cavity of the nail storage tube 23. The nail jamming driving mechanism 28 drives the clamping strip 29 to move horizontally, so that the clamping strip 29 withdraws from the inner cavity of the nail storage tube 23. Then, the plastic glue nails 6 are sequentially placed into the nail storage tube 23, and the plastic glue nails 6 slide downward by their own gravity. When a plastic glue nail 6 slides above the clamping plate 202 (between the upper nail jamming channel 231 and the lower nail jamming channel 232), the nail jamming driving mechanism 28 drives the clamping strip 29 to extend into the upper nail jamming channel 231 and clamp the plastic glue nail 6, so that the plastic glue nail 6 stays at the upper nail jamming channel 231.At this time, the staple sensor 27 detects the presence of the plastic staple 6 and transmits a signal to the staple feeding sensor 203. After receiving the signal, the staple feeding sensor 203 transmits the signal to the staple feeding driving mechanism 201. The staple feeding driving mechanism 201 drives the clamping plate 202 to withdraw from the lower staple channel 232, so that the plastic staple 6 on the clamping plate 202 automatically drops into the staple feeding hose 24 by gravity. At this time, the air blowing pump is started to blow air, and the air flow is blown into the sealing cavity 221 of the lower staple base 22 and the staple feeding hose 24 in sequence through the air blowing pipe 25, and the plastic staple 6 in the staple feeding hose 24 is blown into the tubular staple outlet nozzle 21. The plastic staple 6 enters the inner cavity of the positioning pipe 33 along the tubular staple outlet nozzle 21 under the action of the air flow and maintains a vertical posture by gravity or air flow. By providing the upper staple channel 231 and the lower staple channel 232, as well as the corresponding staple driving mechanism 28, staple sensor 27, staple feeding driving mechanism 201 and staple feeding sensor 203, the falling and supply rhythm of the plastic staple 6 can be accurately controlled. The plastic staple 6 is quickly transported from the lower staple channel 232 to the positioning pipe 33 by blowing air, realizing the rapid supply of staples. Only one plastic staple 6 is allowed to enter the positioning pipe 33 each time, avoiding chaos caused by multiple staples entering at the same time, and improving the accuracy and stability of staple insertion.

[0032] When the staple feeding sensor 203 detects that the plastic staple 6 on the clamping plate 202 has fallen, the staple feeding sensor 203 transmits the signal to the staple feeding driving mechanism 201 and the staple sensor 27 successively: after receiving the signal, the staple feeding driving mechanism 201 drives the clamping plate 202 to extend into the lower staple channel 232 through the staple feeding driving mechanism 201 to seal the inner cavity of the staple storage tube 23; then, the staple sensor 27 receives the signal and drives the clamping strip 29 to withdraw from the upper staple channel 231 through the staple driving mechanism 28, releasing the plastic staple 6 in the upper staple channel 231, so that the plastic staple 6 drops above the clamping plate 202. After that, when the staple sensor 27 detects that the plastic staple 6 in the upper staple channel 231 is not stuck, the staple sensor 27 transmits the signal to the staple driving mechanism 28 and the staple feeding sensor 203 successively: after receiving the signal, the staple driving mechanism 28 drives the clamping strip 29 to extend into the upper staple channel 231 through the staple driving mechanism 28 to clamp the plastic staple 6 in the upper staple channel 231; then, the staple feeding driving mechanism 201 receives the signal and drives the clamping plate 202 to withdraw from the lower staple channel 232 through the staple feeding driving mechanism 201, so that the plastic staple 6 on the clamping plate 202 automatically drops into the staple feeding hose 24. By repeating the above steps, the continuous supply of the plastic staple 6 is realized. At the same time, new plastic staples 6 will be continuously replenished to the upper staple channel 231 to ensure the continuity of staple supply.

[0033] The staple driving mechanism 28 includes a first moving seat 281, a first cylinder 282, a first guide rod 283, and a first compression spring 284. The first moving seat 281 is located outside the lower staple seat 22. The cylinder block of the first cylinder 282 is mounted on the first moving seat 281. The piston rod of the first cylinder 282 extends in the horizontal direction, and the end of the piston rod of the first cylinder 282 is connected to the outer wall of the lower staple seat 22. The staple sensor 27 is electrically connected to the signal input end of the first cylinder 282. The outer end of the first guide rod 283 is mounted on the first moving seat 281. The side wall of the lower staple seat 22 is provided with a first guide hole 223 extending in the left-right direction. The first guide rod 283 is located in the first guide hole 223. The strip 29 is mounted on the inner end of the first guide rod 283.
